(associated methods of electric supply installation 2100)

Below, use Figure 29 and Figure 30, the method that electric supply installation 2100 is combined with connector 2010 is described.Figure 29 and Figure 30 illustrates the section of connector 2010 and housing 2060.Figure 29 illustrates that connector 2010 is embedded in connector fitting portion 2061, and the state of the electrode 2044a not conducting of spring-like terminal 2070 and connector 2010.Figure 30 illustrates and forwards to be pushed by electric supply installation 2100 further from the state of Figure 29, the state of electrode 2044a and spring-like terminal 2070 conducting.

First, the inside of connector fitting portion 2061 put into by the light cable 2 rearward extended from connector 2010 by operator from the side peristome 2061b of housing 2060, and then make light cable 2 along the recess 2093 of fixture 2090.

Below, a part for connector 2010 is inserted into connector fitting portion 2061 from side peristome 2061b or front opening part 2061a by operator.In this condition, operator catches the handle part 2091 of fixture 2090, and electric supply installation 2100 is advanced towards connector 2010.Like this, connector 2010 relatively rearward moves in the inside of connector fitting portion 2061.After electric supply installation 2100 is advanced, as shown in figure 29, the protective cover 2050 of connector 2010 is accommodated in the connector resettlement section 2081 in gate portion 2080, and the rear end face of back casing 2030 abuts with the front end face in gate portion 2080.

Figure 29 electric supply installation 2100 is combined with connector 2010 before state under, gate portion 2080 is positioned at the front of connector fitting portion 2061.Under the state shown in Figure 29, the conducting blocking portion 2082 in gate portion 2080 blocks terminal and protrudes hole 2062a.Conducting blocking portion 2082 is the positions of the plate-like portion extended vertically.Conducting blocking portion 2082 is the positions can protruding movement between hole 2062a and installation portion 2066 along the longitudinal direction at terminal.Protrude hole 2062a because conducting blocking portion 2082 blocks terminal, so the conducting portion 2072 of spring-like terminal 2070 abuts with conducting blocking portion 2082, do not protrude hole 2062a from terminal and protrude.Therefore, under the state shown in Figure 29, the electrode 2044a of connector 2010 and spring-like terminal 2070 not conducting.Light-emitting component 2041 not lighting.In addition, the position making spring-like terminal 2070 with the gate portion 2080 of electrode 2044a not conducting is called " second place ".

If from the state shown in Figure 29, electric supply installation 2100 is advanced further, then as shown in figure 30, gate portion 2080 is connected device 2010 and promotes, and relatively rearward moves relative to housing 2060 in the inside of connector fitting portion 2061.Conducting blocking portion 2082 rearward moves compared with protruding hole 2062a with terminal, and terminal protrudes hole 2062a to connector fitting portion 2061 opening.Like this, the conducting portion 2072 of spring-like terminal 2070 protrudes to connector fitting portion 2061 from terminal protrusion hole 2062a due to its elastic force.The conducting portion 2072 protruded contacts with electrode 2044a with opening 2033a through the power supply of connector 2010.Thus, spring-like terminal 2070 and electrode 2044a conducting, supply electric power from electric supply installation 2100 pairs of light-emitting components 2041, light-emitting component 2041 lighting.As noted above, the position making spring-like terminal 2070 with the gate portion 2080 of electrode 2044a conducting is called " primary importance ".

In addition; if from the state shown in Figure 30, operator catches handle part 2091, is rearward pulled by electric supply installation 2100; then protective cover 2050 and connector resettlement section 2081 are with the state be close to, and connector 2010 and gate portion 2080 forwards move integratedly in connector fitting portion 2061.Now, the front end in gate portion 2080 abuts with the rake 2071a of spring-like terminal 2070.Gate portion 2080 is made forwards to move relative to housing 2060 further.So rake 2071a is promoted by the front end in gate portion 2080, conducting portion 2072 moves to radial outside.If the conducting blocking portion 2082 in gate portion 2080 moves to the position that blocking terminal protrudes hole 2062a, then conducting blocking portion 2082 abuts with the conducting portion 2072 of spring-like terminal 2070.Thus, spring-like terminal 2070 is disconnected with the conducting of electrode 2044a, and light-emitting component 2041 is turned off the light.If rearward pulled by electric supply installation 2100 further, then protective cover 2050 departs from from connector resettlement section 2081, and connector 2010 is deviate from from housing 2060.

(effect)

As mentioned above, electric supply installation 2100 involved according to the present embodiment, housing 2060 has for the chimeric connector fitting portion 2061 in the rear portion of connector 2010, under the state that the rear portion of connector 2010 is chimeric with connector fitting portion 2061, spring-like terminal 2070 can with electrode 2044a conducting.

Therefore, by electric supply installation 2100 is close from rear relative to connector 2010, electric supply installation 2100 is forwards moved, thus electrode 2044a and spring-like terminal 2070 conducting can be made.As noted above, use the space at the rear of the connector 2010 can guaranteeing larger by working space, can power to light-emitting component 2041.Therefore, make the light-emitting component 2041 of connector 2010 luminous and determine that the identification operation of specific light cable 2 becomes easy.

In addition, if use above-mentioned electric supply installation 2100, even if then hand leaves from handle part 2091 by operator, connector 2010 is also not easily deviate from from connector fitting portion 2061, therefore, it is possible to continue the conducting state of maintenance electrode 2044a and spring-like terminal 2070.Therefore, operator easily makes electric supply installation 2100 and connector 2010 conducting arranged in an end of light cable 2, hand is left from electric supply installation 2100, confirms the lighting state of the light-emitting component 2041 of the connector 2010 arranged in another end of light cable 2.

In addition, electric supply installation 2100 involved according to the present embodiment, gate portion 2080 possesses the connector resettlement section 2081 of being accommodated at the rear portion of connector 2010, in the inside of connector fitting portion 2061 along the axially movably setting of light cable 2.In addition, this gate portion 2080 is set to and can moves to primary importance and the second place, primary importance is the position conducting portion 2072 of spring-like terminal 2070 being protruded to connector fitting portion 2061 side and makes spring-like terminal 2070 and electrode 2044a conducting, the second place be conducting blocking portion 2082 abut with conducting portion 2072 and conducting portion 2072 not to the position that connector fitting portion 2061 side is protruded.

Namely, move vertically by making gate portion 2080, switched conductive state and nonconducting state, therefore the space of the side of the connector 2010 that working space is little without using connector 2010 intensive configuration, the rear of the connector 2010 can guaranteeing large working space can be used to carry out operation, and thus workability is good.

In addition, when not arranging gate portion 2080, if make electric supply installation 2100 move along the longitudinal direction, then conducting portion 2072 moves with under the state contacted around power supply opening 2033a in maintenance.When being made up of back casing 2030 resin, the possibility that back casing 2030 damages due to metal conducting portion 2072 can also be expected.Therefore, as noted above, gate portion 2080 is preferably set, only when electrode 2044a to be positioned at position (primary importance) of regulation relative to housing 2060, conducting portion 2072 is protruded from terminal accommodating portion 2062.

In addition, electric supply installation 2100 involved according to the present embodiment, is provided with the latching portion 2065 gate portion 2080 being held in primary importance and the second place at housing 2060.Therefore, easily the conducting state of electrode 2044a and spring-like terminal 2070 or nonconducting state are maintained its state with former state.In addition, also latching portion 2065 can be set to gate portion 2080 is only held in any one in primary importance and the second place.Also can replace latching portion 2065, as shown in figure 31, in the inside of housing 2060, arrange gate portion 2080 all the time towards spring members 2067 spring members 2067 of second place pressing.

Figure 31 is the figure corresponding with Figure 29 of the electric supply installation involved by variation of the 3rd embodiment.In the example shown in Figure 31, be provided with by the spring members 2067 of the state compressed at the rear in gate portion 2080.Due to this spring members 2067, gate portion 2080 is forwards pressed all the time, and conducting blocking portion 2082 blocks terminal and protrudes hole 2062a.

In addition, electric supply installation 2100 involved according to the present embodiment, when gate portion 2080 is positioned at rear relative to housing 2060, be set to the primary importance of conducting portion 2072 and electrode 2044a conducting, when gate portion 2080 moves to front than primary importance, be set to the second place of conducting portion 2072 and electrode 2044a not conducting.That is, primary importance is compared with the second place, and gate portion 2080 is positioned at the rear of housing 2060.If operator makes housing 2060 forwards move towards connector 2010, then gate portion 2080 retreats relative to housing 2060, can make light-emitting component 2041 lighting.Therefore, powered operation intuitively easy understand.

In addition, electric supply installation 2100 involved according to the present embodiment, at the rear of housing 2060, is provided with the fixture 2090 at the rear portion being detachably installed on housing 2060.Connector 2010 is smaller parts.The housing 2060 of this little connector 2010 chimeric also becomes smaller parts.Therefore, operator is not easy directly to catch housing 2060.Therefore, the large fixture easily caught is set by using the large working space at the rear of connector 2010, thus the operability of electric supply installation 2100 can be improved.

In addition, electric supply installation 2100 involved according to the present embodiment, by the recess 2064 making the claw 2095 of fixture 2090 be inserted into housing 2060, thus holds housing 2060 by pincers portion 2092.Thereby, it is possible to using the axle by a pair claw 2095 as rotation center, fixture 2090 rotates relatively relative to housing 2060.

Therefore, though operator identification operation in mistakenly to fixture 2090 to the direction acting force that the axis with light cable 2 is intersected, fixture 2090 rotates, and this power also can not act on housing 2060 and connector 2010.Therefore, suppress mistakenly connector 2010 to be damaged in identification operation.

In addition, even if when the limited space at the rear of connector 2010, also can, from the oblique rear of connector 2010, fixture 2090 be used to make connector 2010 be embedded in housing 2060.

The angle being preferably limited to one-sided 15 degree ~ 45 degree (30 degree ~ 90 degree, both sides) left and right centered by the axial direction of light cable 2 relative to the rotation of housing 2060 of fixture 2090.If too freely rotated, be then difficult to contraposition when housing 2060 being moved holding handle part 2091.On the other hand, if rotation amount is very few, then the power on the direction intersected with the axis of light cable 2 putting on fixture 2090 is difficult to avoid.

In addition, electric supply installation 2100 involved according to the present embodiment, is provided with the recess 2093 along the axially open of light cable 2 at fixture 2090.In identification operation, recess 2093 can be used naturally rearward to be extended by the light cable 2 that the rear from connector 2010 extends, not easily excessive bending force is acted on to light cable 2.

(associated methods of electric supply installation)

Below, use Figure 34 and Figure 35 that the method be combined with connector 2010 by electric supply installation 2100A is described.

First, before being combined with connector 2010 by electric supply installation 2100A, conducting blocking portion 2082 is inserted into through hole 2068, makes fixture 2090A advance to the conducting blocking portion 2082 pairs of terminals relative to housing 2060A and protrude the position that hole 2062a cover.In this condition, conducting blocking portion 2082 abuts with the conducting portion 2072 of spring-like terminal 2070A, and conducting portion 2072 does not protrude to connector fitting portion 2061.

, keep this state below, connector 2010 is fitted together to connector fitting portion 2061, electric supply installation 2100A is advanced.In this condition, as shown in figure 35, because conducting blocking portion 2082 is between spring-like terminal 2070A and electrode 2044a, so spring-like terminal 2070A and electrode 2044a is nonconducting state.In this condition, light-emitting component 2041 is turned off the light.Position spring-like terminal 2070A and electrode 2044a being become the gate portion 2080A of nonconducting state is also called the second place.

From this state, operator's push portion 2098, makes protruding 2099 to depart from from opening 2069.Make fixture 2090A retreat further, fixture 2090A is extracted out from housing 2060A.Thus, conducting blocking portion 2082 is protruded hole 2062a from terminal and is rearward moved, and the conducting portion 2072A of spring-like terminal 2070A protrudes to connector fitting portion 2061 side due to elastic force, conducting portion 2072 and electrode 2044a conducting.Thus, light-emitting component 2041 lighting.Conducting portion 2072 this is made also to be called primary importance with the position of the gate portion 2080A of electrode 2044a conducting.

When being unloaded from connector 2010 by electric supply installation 2100A, conducting blocking portion 2082 is inserted into through hole 2068, fixture 2090A is assemblied in housing 2060A again.Fixture 2090A is advanced, till the projection 2099 of fixture 2090A is embedded in the opening 2069 of housing 2060A relative to housing 2060.Under protruding 2099 states being embedded in opening 2069, the terminal of conducting portion 2072A and terminal accommodating portion 2062 that conducting blocking portion 2082 enters spring-like terminal 2070A protrudes between the 2062a of hole, and spring-like terminal 2070A and electrode 2044a becomes nonconducting state.Thus, light-emitting component 2041 is turned off the light again.

Further, if operator not push portion 2098 and make fixture 2090A retreat, then because protruding 2099 are embedded in opening 2069, so housing 2060A also retreats together with fixture 2090A.Thus, connector 2010 forwards departs from from the connector fitting portion 2061 of housing 2060A, and the combination of electric supply installation 2100A and connector 2010 is removed.
