Abstract
An electrical connector (1') having a generally C-shaped member (2') for electrically connecting wires (30') with a wedge member (12'). The C-shaped member (2') comprises radially arranged recesses (7') and holding teeth (10') which are adapted to provide tensile strength to the wedge member (12') for retaining the wires (30').
Indicia marks (A,B) are provided for correct sizing of the connector relative to the wires (30'). Figure 6.
Indicia marks (A,B) are provided for correct sizing of the connector relative to the wires (30'). Figure 6.
Description
213~1~8 -, applied to new or used connectors, both in the C-shaped outer member and in the second wedge type inner member.
The problems of the known connectors are overcome by providing an electrical cable connector which has a first C-shaped element and a second wedge shaped element, each capable of retaining electric cables, the first and second elements being secured by folding flexible sheet metal.
The first C-shaped element has beaded flanges at its loose ends, and, on the bottom part, an orifice suitable for fitting a ridge provided on the rear part of the second wedge type element, characterized by the fact that at least two marks are foreseen in at least one of the components.
An additional purpose of the present invention is to provide teeth arranged in the C-Shaped member, in a place where it is permitted that the teeth be spaced apart along the length of the C-shaped member, thus permitting an increase of the tensile strength of the connecting cables.
The present invention will now be described with the reference to the accompanying drawings, in which:
Figure 1 is a perspective view of the top part of the connector assembly showing the first C-shaped element, the electric cable and the second wedge type element being wedged in to form the connector assembly.
Figure 2 is a perspective view of the bottom part of the connector assembly which also shows the wedge type element being inserted in the C shaped element.

Figure 4 is a perspective view showing a sectioned portion of the C-shaped member Figure 3 taken along line 4-4 of Figure 3.
Figure 5 is a frontal perspective view showing the present invention in an assembled state.
Figure 6 is a perspective view of the assembled connector, showing the cables arranged in the ocnnector assembly.
Referring to Figures 1-2, one can determine the connector assembly 1 comprised of a first C-shaped outer 21341~~
7 of C-shaped element 2 to clamp the cables 30 in the connector assembly.
With the wedge type connectors a great variety of combinations of conductor cable are made possible, being limited solely to the sum of the minimum and maximum conductor combinations, varying in accordance with a specific cable diameter for each type of conductor.
The present invention has the purpose of providing an alternative arrangement to the known connectors, which will permit the technician to determine which is the correct type of connector for an as yet unknown arrangement in conductor cables, without damaging the connectors (as it will not be necessary to assemble them beforehand) .
It is possible to determine the type of connector without previously assembling the connectors by the incorporation of marks, preferably two already pre-determined ones, in the C-shaped element 2, in the wedge type element 3, or in both of them.
The marks may be made in the first and second elements of the connectors during their manufacture or later, and they may be superficial marks such as obtained by painting, center punching, or any other means.
As is shown in Figures 1 and 2, the position of mark A indicates the limit of acceptance of the connector in accordance with the maximum sum of combinations of the cable diameters. The position of mark "B" indicates the l_ \
limit of acceptance of the minimum sum of the combination of cables.
With marks A and B it is possible for the technician to check, before applying the connector, whether the type of connector chosen is correct, without risk of utilizing an unsuitable connector.
As a practical example it may be cited that, as seen from Figure 1, the fact that the frontal part of the wedge is situated between marks A and B indicates that the sum of the diameters of the conductor cables is within the specific maximum and minimum limits for this type of connector. Marks A and B are foreseen on both free edges 4 of the first C-shaped element 2.
As mentioned previously, marks A and B may alternatively be made in the second wedge type element 3 (see Figure 2) for the purpose of aiding the installer to visualize the assembly of the connector when seen from the other side of same.
In a second embodiment, as shown in Figure 2, the rear part of the C-shaped element 2 is placed between ,....
marks A and B, which indicates that the sum of the diameters of the conductor cables is within a specific minimum and maximum limit for the chosen connector.
Another embodiment of the present invention is shown in Figures 3-6, Connector 1' comprises two pieces which fit together to secure conductor cables 30' between them.
2134~.~8 One of the pieces is a member 2' of generally C-form which is stamped and formed from a sheet, usually from sheet metal, which is bent in the shape of a "C'°. In the bottom portion 3' is provided a ramp 4' adjacent to an opening 5'.
Receptacle 2' has at least two radially arranged recesses 7' forming inwardly directed channels 8 and outwardly directed protuberances 9'.
The inner portion of receptacle 2' is provided with a plurality of holding teeth 10' which are longitudinally spaced apart along the length of the receptacle 2'.
The holding teeth 10' are preferably provided, in the inner side wall 11' of receptacle 2', in the concave portion of the same, are in the shape of notches, which shape is suitable to increase the tensile strength of the cables in the connector. In the embodiment of the present invention, the notches have a diamond shape. It should be noted that the diamond shape is an illustrative shape and not a restrictive one.
Teeth 10' can be arranged in a way to be inserted between the two recesses 7' in order to provide a greater tensile strength to the receptacle 2' to better distribute the tension of the connection along the cables and to permit an increase of the tensile value of the cables in the connector assembly.
The other piece of the connector assembly 1' is a wedgeshaped member 12' comprised of a sheet material, :.., 213~15~
preferably of sheet metal which is folded inwardly forming two cylindrical portions 13' and 14', having channels 15' and 16', respectively, which will secure and tense up cables 30' against the wall 11' of receptacle 2'.
