Abstract

The utility model discloses a kind of spring-piece type binding post that is easy to wiring, comprise insulating part (1), drive block (2), one or more groups conducting strip (3), one or more groups shell fragment (4) and one or more groups support chip (5).It is mobile that this binding post promotes drive block (2) by external force, drive block (2) drives one end of shell fragment (4) to produce strain, support chip (5) supports the other end of shell fragment (4), for preventing that shell fragment (4) from movement in addition occurring to set; Shell fragment (4) can form gap with conducting strip (3) after producing deformation, and wire inserts this gap through insulating part (1); After external force is removed, shell fragment (4) resilience clamping wire, thus arrive the object being electrically connected.

Description

A kind of spring-piece type binding post that is easy to wiring

Technical field

The utility model relates to a kind of low voltage switchgear and control appliance ancillary apparatus, especially a kind of electrical connection arrangement of using for secondary equipment in power system wiring.

Background technology

Existing spring-piece type binding post, generally arranges wiring window in one end of shell fragment, and other end bending and molding is fastened in wiring window, because shell fragment head and the tail snap together each other, will greatly increase die cost; During assembling, the head and the tail that need to use frock clamp that shell fragment is snapped together are opened, then conducting strip is inserted into shell fragment is opened from beginning to end and in the gap that forms, has so greatly increased cost and the assembling time cost of equipment investment; During wiring, drive shell fragment distortion to need larger strength just can complete, cause operating difficulties.

Summary of the invention

For deficiency of the prior art, the utility model proposes a kind of spring-piece type binding post that is easy to wiring.The spring-piece type binding post that this is easy to wiring, comprises insulating part, drive block, one or more groups conducting strip, one or more groups shell fragment and one or more groups support chip; Its shell fragment comprises turning arm, registration arm and support arm; Registration arm one end is connected with turning arm by bending part one, and one end is connected with support arm by bending part two, and turning arm and support arm are provided with angle.So can adopt common bending molding process, die cost is low; During assembling, auxiliary without frock clamp, reduce equipment investment and assembling time cost; During wiring, screwdriver promotes drive block, and drive block drives shell fragment distortion, greatly reduces shell fragment and is out of shape required strength, has so reduced operation easier.

Embodiment

In order more clearly to understand the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection range of the present utility model is not limited in following examples.

As shown in Figure 1, embodiment of the present utility model is: a kind of spring-piece type binding post that is easy to wiring, comprises insulating part 1, drive block 2, one or more groups conducting strip 3, one or more groups shell fragment 4 and one or more groups support chip 5; It is characterized in that: described shell fragment 4 comprises turning arm 41, registration arm 42 and support arm 43; Registration arm 42 one end are connected with turning arm 41 by bending part 1, and one end is connected with support arm 43 by bending part 2 45, and turning arm 41 and support arm 43 are provided with angle.

As shown in Figure 2; in execution mode of the present utility model; the support arm 43 of shell fragment 4 is supported on support chip 5; screwdriver A applies external force F1 on drive block 2; drive block 2 is subjected to displacement and makes the turning arm 41 of shell fragment 4 around registration arm 42 rotations of shell fragment 4; thereby whole shell fragment 4 deforms, after shell fragment 4 distortion, the cutting edge 46 on shell fragment 4 can form gap with conducting strip 3; Now under the effect of F2, wire B inserts this gap by the window C of insulating part 1, then cancels external force F1, and shell fragment 4 resilience clamping wire B so can make wire B and conducting strip 3 fitting together tightly, thereby realizes the function of electrical connection.

As shown in Figure 3, be provided with boss 21 on drive block 2, boss 21 reduces from top to bottom gradually.

As shown in Figure 4, on insulating part 1, be provided with muscle E.

As Fig. 5, shown in Fig. 6, it is upper that the upper end D face of the boss 21 arranging on drive block 2 is fastened on the muscle E of insulating part 1, so can prevent that drive block 2 from freely deviating from insulating part 1.
