COMPLETE SPECIFICATION STANDARD PATENT Invention Title: ELECTRICAL WEDGE CONNECTOR The following statement is a full description of this invention including the best method of performing it known to us:- J 4I -lA- ELECTRICAL WEDGE CONNECTOR This invention relates to electrical connectors comprising a wedge receivable in a wedge shaped receptacle of generally C-shaped cross section and adapted to secure conductor wires between the sides of the wedge and channels of the receptacle.
It is known from Brazilian patent PI 8202511 to provide a wedge connector having a wedge formed from sheet metal and a wedge shaped receptacle for receiving the wedge and thereby compressing conductor wires between the sides of the wedge and the channels of the receptacle.
In the electrical wedge connector according to the present invention, the channels are provided with teeth 15 formed by skiving which penetrate the wires to increase the tensile value of the connector.
fexample with reference to the accompanying drawing in which: FIGURE 1 is a perspective view of the w ge shaped :receptacle according to the invention; FIGURE 2 is an end sectioned view the assembled connector showing the wires contacti the teeth in the channels; and FIGURE 3 is a sectioned s' e view of a tooth.
The wedge 10 shown in Fgure 2 is substantially the same as shown in the abov mentioned Brazilian patent PI 8202511. It is sta ed and formed from sheet metal and has a central w 12. The sides 14 are turned back in towards web 1 to provide outwardly facing surfaces 16 which are eferably concave as shown.
A loc J g nub 18 projects outwardly from end 20 of central b 12.
Sdge shaped receptacle 26, shown in Figure 1, is al substantially the same as shown in the lb In one embodiment, the invention consists in an electrical wedge connector comprising: a wedge received in a wedge shaped receptacle to compress conductive wires in channels in the receptacle; wherein the channels include wire penetrating teeth at four locations, fixedly formed in said channels by skiving at ends of the channels; and wherein said teeth include sharpened edges for digging into said conductive wires; whereby said teeth frictionally retain said wires in said channels when an axial force is applied to said wires which tends i- separate said wires from said channels.
The invert ion will now be described by way of example with reference to the accompanying drawings, in which: Sege e: 15 Fig 1 is a perspective view of the wedge shaped C* CS receptacle according to the invention; Fig 2 is an end sectioned view of the assembled connector showing the wires contacting the teeth in the channels; and Fig 3 is a sectioned side view of a tooth.
S" The wedge 10 shown in Fig 2 is substantially the same as shown in the above mentioned Brazilian patent PI 8202511. It is stamped and formed from sheet metal and has a central web 12. The sides 14 are turned back in @555 25 towards web 12 to provide outwardly facing surfaces 16 which are preferably concave as shown.
9:04 A locking nub 18 projects outwardly from end 20 of Sooo central web 12.
Wedge shaped receptacle 26, shown in Fig 1, is also 30 substantially the same as shown in the aforementioned Brazilian patent. Receptacle 26 is C-shaped in cross section and tapers from one end towards another to conformably receive wedge Receptacle 26 is stamped and formed from sheet metal and has inwardly facing channels 28 formed by rolling side edges 30 up and around as shown. Channels 28 are joined by web 32. Ramp 34 at end 36 of web 32 leads to opening 38. Stop member 40 is provided at the opposite end 42 of web 32.
The present invention relates to teeth or wire penetrating projections 50 formed from the material of the receptacle 26 in channels 28 at one end 52 )r at both ends 52,54 as shown. Teeth 50 are formed by skiving the metal at the edges as shown in Figure 3.
The teeth 50 are formed to be parallel to the conductor oeo i S 15 wires 56,58 as shown in Figure 2. Teeth 50 penetrate respective wires 56,58 as the wires are compressed into channels 28 by wedge 10 being driven into the receptacle 26.
Figure 2 shows an assembled wedge connector 62 with conductor wires 56,58 secured in between concave osurfaces 16 on wedge 10 and channels 28. Teeth 50 have penetrated the wires 56,58 to improve the tensile value of the connector 62.
The wedge 10 is locked in receptacle 26 by locking nub 18 being received in opening 38.
In the embodiment shown, one concave surface 16 is smaller than the opposite surface to receive smaller diameter wire 56.
Changes in construction will occur to those skilled in the art and various apparently different modifications and embodiments may be made without departing from the scope of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only. It is therefore intended that the foregoing description be regarded as illustrative rather than limiting.
