Description

(54) IMPROVEMENTS IN OR RELATING TO ELECTRICAL CONNECTORS (71) We, KRONE GMBH, a German Company, of Goerzallee 311, 1000 Berlin 37, West Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: - The invention relates to an electrical connector for insulated wire, comprising a terminal element made of planer, resilient, contact material and formed with a slot having a relatively narrow main portion and a relatively wide opening, the walls defining said slot having sharp edges so that when a wire is pressed into the slot its insulation is cut and contact established between the terminal element and wire, and a clamping element which is associated with the terminal element and is intended for gripping the insulated wire.
The invention relates to an improvement in such a connector whereby the construction of the individual connector is such that a substantially larger number of such connectors can be accommodated in a smaller space.
According to the present invention there is provided an electrical connector for insulated wire, comprising a terminal element made of planar, resilient, contact material and formed with a slot having a relatively narrow main portion and a relatively wide opening, the walls defining said slot having sharp edges so that when a wire is pressed into the slot its insulation is cut and contact established between the terminal element and wire, and a clamping element which is associated with the terminal element, said clamping element being formed of insulating material and being intended for gripping the insulated wire, the clamping element having a longitudinally extending slot for receiving the insulated wire, the terminal element being mounted on a carrier plate and disposed in said slot such that the plane of the terminal element is at an angle of substantially 45" to the axis of the slot.
One embodiment of the present invention will be described now by way of example only with particular reference to the accompanying drawings in which: Figure 1 is a perspective view of part of a terminal strip, with three double terminal elements Figure 2 is the plan view of part of the terminal strip according to Figure 1, Figure 3 is a section along the line I-I of Figure 2; Figure 4 is a side view of a complete terminal strip according to Figures 1 to 3; Figure 5 is a plan view of the terminal strip according to Figure 4, and Figure 6 is a view of the endface of the terminal strip according to Figures 4 and 5.
An electrical connector for one or more insulated wires or cable cores 3 comprises a terminal element 10 which is constructed of metal and a clamping element which is constructed of plastics as part of an insulating member 20a (Figure 1). The clamping element 20 has a vertical slot 22 which extends longitudinally of the clamping element, ie. longitudinally with respect to the rectangular cross-sectional surface area 21 of the insulating member 20a, and into which slot the wire 3 is inserted. The terminal element 10 is arranged at an angle of 45" to the slot 22 and is surrounded by the clamping element 20.
The clamping element 20 is attached to a carrier plate 23a thus constituting a structural unit 24 in which the terminal element 10 is also fixedly disposed (Figures 1 and 2).
The wire 3 is connected by being inserted manually into the slot 22. The wire then engages behind a retaining device 20d and is situated in an enlarged opening 10e of the terminal element 10. The wire 3 is moved into its clamping and connecting position by means of a setting tool. In this operation the wire 3 is pressed into a contact slot 10d. Due to the terminal element 10 being set at an angle the edges of the walls of the slot 10d penetrate through the insulation of the wire 3 and contact the wire at its core. The wire 3 is simultane ously cut off by the setting tool.
To secure the connecting wire the clamping element 20 is provided with four clamping studs 20e which penetrate into the insulation of the wire and provide an effective cord grip.
To additionally secure the wire 3 it is guided through wire ducts 25, 25' upstream of the connecting place and is again guided over a ratchet device 20b (Figures 2 and 3).
As indicated in Figure 3 every two terminal elements 10 and 10' together with a transverse web 10a are combined into one unit. Every two or all clamping elements 20, 20', 20" . . . are likewise connected to each other. This double terminal element 10 and 10' is retained centrally in a guide strip 23b of the carrier plate 23a.
Between the two terminal elements 10 and 10' the cross web 10a supports a contact spring 10b for accommodating an overvoltage arrester (Figure 3).
The complete structural unit of the electrical connector 24 is obtained by joining together a plurality of portions 23 in which one half of the clamping element 20 is combined into one unit with the adjacent half 20' (Figure 1).
To combine several wires 3, for example in the form of a cable harness, each of the two ends as well as the middle bottom of the carrier plate 23a of the complete electrical connector 24 is provided with a wire guide loop 28 and 28' as indicated in Figures 1, 4 and 6.
Each of the endfaces of the structural unit 24 is provided with a mounting screw 27 for mounting on a rack not shown (Figures 1 and 5).
Each of the ends of the carrier plate 23a supports an earthing contact 29, as indicated in Figures 1 and 2, for receiving an overvoltage arrester.
As can be seen more particularly by reference to Figures 4 to 6 the complete terminal strip, based on the previously described details of the invention, can be manufactured in a very compact construction, thus permitting substantially improved utilisation of the available space.
