Description

Wire termination

Technical field

The present invention relates to a kind of wire termination.

Background technology

Existing electric wire joins, and is to come for it with the mode of hinge joint, and then twines the coated insulation adhesive plaster in the place of hinge joint; But this kind connects the mode of electric wire with hinge joint, and not only construction is inconvenient, and insulating tape also is easy to rottenly lose stickiness and come off, and causes the danger in the use.

For improving above-mentioned shortcoming, by there being the dealer to design a kind of binding post, it is fixing to provide electric wire to connect with the mode of pegging graft, for example: No. 200710109779.0 patent application case of China; And look into; To shown in Figure 3, this kind binding post consists predominantly of a terminal board 10, is provided with a spring steel plate 16 and a current bus 17 in the terminal board 10 like Fig. 1; The open end of terminal board 10 is provided with a panel 11; Panel 11 is provided with a plurality of electric wires and penetrates hole 12,13,14, cuts and forms a spring tongue piece 21 and penetrate on the spring steel plate 16 in hole 12,13,14 each punching press in corresponding electric wire, and make this position form a window 211.

By above-mentioned structure, like Fig. 2, shown in Figure 3, during use; Earlier the line end of electric wire 15 is peelled off the insulation epidermis; Make the conducting end 18 of its exposed suitable length, then this conducting end 18 is penetrated hole 12 by the lead on the panel 11 and insert terminal board 10 interior extremely location, the conducting end 18 of electric wire 15 can be passed window 211; And receive free end 20 roof pressures of spring tongue piece 21; Make the conducting end 18 of electric wire 15 be tight and contact, and then by the conduction of

current bus

17,15 formation of electric wire 15 and electric wire that order is plugged in the terminal board 10 equally are connected conduction with the free end 171 of current bus 17; Utilize the free end 20 of spring tongue piece 21 to form a unidirectional clip effect simultaneously, avoid being reversed of electric wire 15 to detach terminal board 10; Whereby, reaching electric wire 15 fixed with being connected of electric wire 15.

Yet, above-mentioned binding post, though can provide construction more convenient, and use safer advantage, connect the existing shortcoming of electric wire and improve existing mode with hinge joint; But because the relation of its structural design, the conducting end 18 of electric wire 15 only can be done with the free end 171 of the free end 20 of spring tongue piece 21 and current bus 17 and contact conduction (like Fig. 2, shown in Figure 3); So that the area of its contact conduction is very little, almost only be contact a little, therefore except electrical efficiency is not good; And easy thereby generation high temperature; The elasticity of spring tongue piece 21 is degenerated, and influence the active force that the free end 20 roof pressure electric wires 15 of spring tongue piece 21 contact with current bus 17, and then will reduce the conductive capability that is connected of

electric wire

15 and 15 in electric wire; Even will cause the loosening disengaging terminal board 10 of electric wire 15, and cause the danger in the use.

In addition; Above-mentioned binding post because the relation of its structural design, penetrates hole 12,13,14 but only be provided with the electric wire that supply lines 15 pegs graft in the panel 11 of one of which end; The electric wire 15 that therefore same direction only can be provided and come is forward pegged graft; The electric wire 15 that different directions comes then must with line body folding around after begin to peg graft so that will cause the inconvenience in the construction, and cause the crowded confusion of electric wire 15 in terminal box.
