Abstract
Description
- This invention relates to electrical supply systems and in particular to such systems of the type comprising a supply track in the form of an elongate channel housing a plurality of conductors extending longitudinally of the channel, a supply connector including terminals for connection of electricity supply leads and contacts connected electrically to the terminals and arranged to contact the track conductors on engagement of the connector in the track for supplying electrical power to the conductors, and one or more adaptors engageable in the track at any selected position along its length and including contacts engageable with the conductors for supplying electric power to an electrical appliance wired to the adaptor. The invention is especially concerned with a novel supply connector for such an electrical supply system.
- In electrical supply systems of the kind described above which are currently available on the market, the supply connectors are all fitted to an end of the track by pushing the connector through the open end of the track. Unlike the adaptors which must project to a greater or lesser extent through the open mouth of the track in order that they may be inserted into and removed from the track at will, once the supply connector is fitted to the track it is not necessary or usual for it to be removed or adjusted so fitting it into the track through the end of the channel has the advantage that the connector need not protrude through the channel mouth and in some cases can be accommodated entirely within the channel with clear benefits from an aesthetic point of view. Having to push the connector in through the end of the track also has some disadvantages, however. The normal installation procedure is to wire the connector to the electricity supply leads and insert it into the track after the. latter has been mounted in position, which means that sufficient space must be left at the end of the track to enable the connector to be fitted to the track. In addition, a certain amount of slack is inevitably left in the supply leads which are not then always easy to conceal and they can be unsightly if left exposed to view.
- The present invention aims at eliminating or reducing the above disadvantages by ;providing a supply connector for an electrical supply installation of the kind initially described, which is arranged to be inserted into the track through the open mouth of the channel and to be accommodated substantially entirely within the channel.
- By making the connector so that it can be inserted through the open mouth of the channel a space is no longer needed at the end of the track which may be mounted to abut against a wall, for example, should this be desirable in any installation. The slack in supply leads can be reduced and they may be more easily concealed in the track. Furthermore the connector may be positioned away from the track end should this prove convenient or desirable. At the same time the advantage of the connector being completely concealed within the track is not surrendered.
- Supply connectors for continuous outlet electrical distribution tracks should not be confused with the adaptors which are fitted to the track and serve as current take-off devices for supplying power to electrical appliances. The most fundamental requirement of an adaptor is that it should be insertable into the track through the channel mouth and at any selected position along the track length. This versatility of the adaptors is an important feature of track systems. In contrast supply connectors have in the past always been so made that they must be inserted into the end of the track. The additional advantages which accrue from the extra versatility obtained by making the supply connector so that it can be introduced into the track through the channel mouth have hitherto gone unrecognised, in spite of the fact that supply connectors are used side by side with adaptors. Although it might be thought surprising this confirms the point that supply connectors are as a practical matter looked upon in the art as quite different to adaptors.
- In British Patent Specification No.GB 1436707 there is proposed a supply connector which is illustrated in Figures 5-7 of said specification and comprises a generally rectangular body in which are mounted terminals for connection of the current supply leads and elongate contacts extending generally in parallel and longitudinally of the body, each contact having one end connected to a terminal and the other end protruding laterally through an opening in the body. Although the body is adapted to be inserted through the open end of the track member a modification is suggested to enable it to be introduced through the channel mouth. A second component of the connector consists of a mechanical wedge which is inserted into the track channel and moved longitudinally to engage with a wedging action between the body and a side wall of the track channel in order to clamp the body to the track and press the contacts into engagement with the track conductors. The wedge includes a portion which projects through the mouth of the track channel to enable it to be displaced and a locking screw must be tightened to hold the wedge and body assembled in the operative position. The supply connector disclosed in the prior specification has several drawbacks. It is suitable only for use with tracks having conductors supported at one side only of the track channel, whereas many supply tracks have conductors at both sides. With the connector being made in two separate parts there is a danger that the wedge may not be assembled properly with the body, or it could even be omitted completely. Since the wedge serves to clamp the body to the track and to press the contacts against the conductors it is difficult to ensure that the correct clamping and contact pressures are achieved. Furthermore, a part of the connector protrudes through the channel mouth and detracts from the visual appearance.
- According to the present invention there is provided a supply connector for connecting to a source of electric current the conductors of a current distribution track member having an elongate channel housing a plurality of conductors extending longitudinally of the channel, the connector comprising a generally rectangular housing dimensioned to be received in the channel, a plurality of terminals mounted in the housing for connection of electric current supply leads, a plurality of elongate electrical contacts mounted to extend generally in parallel and longitudinally of the housing, each contact having one end connected to one of the terminals and the other end arranged to protrude laterally through an opening in the housing for engaging a respective conductor of the track member, and a cam member movable longitudinally of the housing for adjusting said other ends of the contacts laterally for engaging the track conductors, characterised in that the contacts are resilient and mounted in cantilever manner adjacent said one ends to enable the other free ends thereof to move between retracted positions within the housing and operative positions projecting through the housing openings, the cam member is slidable in the housing and cooperates with the contacts for adjusting the free ends of the contacts between their retracted and operative positions, and drive means is coupled to the cam member for displacing the cam member longitudinally of the housing and contacts and includes an operating member movably mounted to the housing, the connector, with the contacts retracted, being insertable as a unit into the track channel through the mouth thereof after which the operating member is operable to adjust the contacts into their operative positions for engaging the track conductors with the connector supported by and accommodated substantially entirely within the track member.
- As the contacts can be selectively withdrawn into the housing contacts can be arranged to project from both sides of the housing for engaging conductors mounted on opposite sides of the track channel. The connector is insertable into the channel as a unit and once in position the mounting procedure is completed in a simple manner by manipulation of the operating member. The connector construction remains comparatively simple through the use of resilient cantilevered contacts.
- Most of the supply tracks currently available on the market have channels of such a small width that there is insufficient space available for a rotary cam for acting directly on resilient cantilevered contacts, but by employing a sliding cam member in the supply connector of the invention it has been found possible to use such contacts, which are preferred since they preclude the need for separate springs or more complex contact arrangements, thereby simplifying assembly procedures and costs.
- In a preferred embodiment of the invention the drive means comprises a rack and pinion drive including a rack connected to the cam member for displacement therewith and a pinion in mesh with the rack and having its axis normal to the housing side walls, the operating member being a lever fast with the pinion and actuable from outside of the housing for adjusting the contacts between their extended and retracted positions. The rack and pinion drive ensures an adequate mechanical advantage for displacing the cam member which assists to enable the operating parts to be received entirely within the track channel.
- The pinion may conveniently consist of a toothed quadrant fast with the lever, and the latter may be L-shaped and have one limb fixed to the pinion while the other limb is arranged to lie against the bottom wall of the housing when the contacts are extended.
- In order to easily control the contact pressures between the contacts and track conductors it is preferred that the contacts be urged to the operative positions by their inherent resilience and the cam member be arranged to act on the contacts to cam them inwardly to the retracted positions. To relieve the contacts of load bearing forces the connector is preferably provided with laterally projecting receiving elements for engaging the track to support the connector, and the cam member arranged to hold these elements in firm engagement with the track when the contacts are extended. Conveniently the elements are resilient tongues integral with the side walls of the housing.
- A more complete understanding of the invention will be had from the following detailed description, reference being made to the accompanying drawings in which:-
- Figure 1 is a side view of a connector in accordance with the invention;
- Figure 2 is a view showing the connector in end elevation and fitted within a track which is shown in cross-section;
- Figure 3 is a side view of the connector with the adjacent side of the housing removed;
- Figure 4 is a similar view to Figure 3 but showing the connector with the contacts in a retracted condition ready for insertion into or removal from a track;
- Figure 5 is a half section taken along the line A-A in Figure 3, the half not illustrated being a mirror image of that shown; and
- Figure 6 is a section taken along the line B-B in Figure 3.
- The supply connector illustrated in the drawing is intended for use with a track of the form shown in Figure 2 and comprising an elongate channel I of uniform profile carrying electrically insulating
inserts 2 adjacent the inner side walls of the channel, and an earth conductor 3 running along the inner end wall. Eachinsert 2 supports three longitudinally extending conductors 4 contact with which can be made from the inside of the channel throughcontinuous slots 5 defined by the inserts. The connector of the invention is inserted into the track for supplying electrical power to the track conductors 4, adaptors being engageable in the track at any position along its length for connecting the conductors to electrical apparatus or appliances, e.g. lighting equipment wired to the adaptors. - The connector comprises a body 6 moulded from electrically insulating material, and a housing formed by two
covers eyelets 9. With exception of an optional polarisingelement 10 described in more detail below, the connector is symmetrical with respect to its midplane. A bifurcated, resiliently bowedearth contact 11 is mounted on the body 6 for contact with the earth conductor 3 of the track, and is held by ascrew 12 which acts as a terminal for an earth lead of the supply cable (not shown). At one end (hereinafter referred to as the inner or forward end) the body carries a cable clamp for gripping the supply cable. On each side the body 6 carries threeterminal blocks 13, theclamping screws 14 of which are accessible through holes provided in the housing covers 7, 8. A respectiveunitary contact element 15 is connected at one end to each terminal block and extends rearwardly in cantilever fashion substantially longitudinally of the connector. Each contact includes aresilient stem portion 15a and a comparativelyrigid blade portion 15b bent to lie in plane normal to the stem portion. Theblade portions 15b are aligned with respectiveelongated slots 16 formed in the housing for thecontacts 15 to protrude from the housing to engage the track conductors 4 as seen in Figure 2. The stem portions of the contacts mounted on opposite sides of the body 6 are separated by aflange 17 havinglongitudinal notches 18 to assist in guiding a dide assembly arranged for longitudinal sliding movement. - The slide assembly consists of two
moulded members windows 22 through which pairs ofadjacent contacts 15 respectively pass, and the inwardly facing sides of which definecam surfaces 23 for acting on the respective c'ontacts. Thecam member 20 also includes on each side a pair of rearwardly projectinglatch fingers 24 with opposed hooks. Thesecond member 21 of the slide assembly includes acentral part 25 on each side of which is formed a pair ofwings 26 aligned with thefingers 24 and extended bytip projections 27 with which the hooks of thefingers 24 engage to hold the twomembers part 25 engaged in central slots provided in top andbottom extension tongues 28 ofmember 20. Themember 21 includes a rack comprising a pair of legs 29 extending rearwardly frompart 25 and toothed on their upper surfaces. In meshing engagement with the rack is atoothed quadrant 30 journalled on an axle provided by a pair of aligned spigots on the housing covers 7, 8 and through which one of the fixing screws oreyelets 9 is fitted. Integral with thequadrant 30 is an L-shapedactuating lever 31 which is movable between the two positions illustrated in Figures 3 and 4 to cause the slide assembly to be driven to and fro within the connector housing by the rack andpinion mechanism contact blades 15 b protrude through thehousing slots 16 due to the resilience of thestem portions 15a, thecam surfaces 23 are moved into engagement with the contacts and press them inwardly to cause the blades to be retracted into the housing through theslots 16. - Each
housing cover resilient tongue 32 defined by a U-shaped slot and provided with a laterally protrudingrib 33 adjacent the free end. These tongues serve to support the connector within the track 1 relieving thecontacts 15 of mechanical loads, by virtue of theribs 33 engaging in thelowermost slots 5 of the track inserts 2, as seen in Figure 2. Thetongues 32 are able to deflect inwardly on insertion of the connector into the track, but when thecam member 20 is moved to its forwardmost position to release the contacts to engage the track conductors, it is positioned behind thetongues 32 and locks them in engagement with the track so that the connector cannot be removed from the track without first retracting thecontacts 15. - The polarising element 10 (see Figures 2, 3 and 6) is optional and may be inserted either way round between the top flanges of the
covers element 10 abuts the earth conductor 3 and prevents complete insertion. If the connector is then turned around the correct way proper insertion is possible, as seen in Figure 2. - In use of the connector the supply leads are connected to the
contact terminals 13 andearth terminal 12, after which the connector may be inserted into the track at either end and either way round (assuming the polarising element is correctly inserted if used) through the open mouth of the track channel. For this purpose thelever 31 is moved to its Figure 4 position so that thecontact blades 15b are withdrawn into the housing by theslide assembly earth contact 11 into engagement with the conductor 3, and theribs 33 oftongues 32 snap into theslots 5 of track inserts 2. Thelever 31 is then rotated to the Figure 3 position in which its limbs lie closely against the end and bottom walls of the housing, respectively, causing the slide assembly to be driven forwardly releasing the contacts so that theblades 15b move out through theslots 16 and engage the respective conductors 4 of the track, and locking the mechanical securingtongues 32 against release. If desired means may be provided to retain the lever in the Figure 3 position and may be arranged to engage automatically with a snap action when the lever is adjusted to this position. - The use of the lever working in a plane normal to the mouth of the track to actuate a rack and pinion system ensures an adequate mechanical advantage to displace the cam assembly controlling the cantilevered contacts, with the result that the connector may be inserted into a track through the channel mouth and be contained wholly within the track.
