Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.

As shown in Fig. 1～Fig. 8, the present embodiment relates to a kind of shell fragment binding post for LED, this binding post Include insulation shell 1, carrying object 2 and wire-clamping device 3, housing 1 bottom-open the cuboid in inner hollow, Housing 1 offers and is available for the wire slot 11 that wire inserts, and carrying object 2 and wire-clamping device 3 are placed in housing 1.

Wherein, carrying object 2 includes integrated electrically-conductive backing plate 21, leg 22 and clamp 23, electrically-conductive backing plate 21 are rectangle strip, and the two ends of this electrically-conductive backing plate 21 each extend over and form a leg 22, and clamp 23 vertically becomes Type on a wherein side of electrically-conductive backing plate 21, another side of electrically-conductive backing plate 21 also forms can with in housing 1 The postive stop baffle 24 coordinated is installed in chamber, in order to increase frictional force, prevents wire from slipping, clamp 23 is additionally provided with many Individual groove 231.

Wire-clamping device 3 includes base 31 and the elastic jig arm 32 with this V-shaped setting of base 31, connects to alleviate The overall weight of line terminals, elastic jig arm 32 is the part that hollow out is turned up from base 31, base 31 and clamp 23 Relatively setting and be disposed in parallel relation to one another, elastic jig arm 32 outwards ejects and has and makes its end draw close to clamp 23 all the time Trend；

It is additionally provided with in elastic jig arm 32 and under external force is ordered about, (as shown by the arrows in Figure 5) this elasticity jig arm 32 can be made End leave the pressing piece 321 of clamp 23, this pressing piece 321 is formed in one in elastic jig arm 32 centre position Recess, recess is the bucket shape shape that top is big, bottom is little, and, recess own elasticity jig arm 32 is to base 31 direction Depression.

Correspondingly, housing 1 offers in the position of corresponding above-mentioned pressing piece 321 (i.e. recess) and is available for outside force application means The through hole 12 that (such as the cutter head of screwdriver, rod-shaped objects etc.) stretch into, wire slot 11 is then opened in the corresponding folder of housing 1 On one side end face of the V-arrangement tip of line apparatus 3, i.e. the direction of insertion of wire and the clamp direction that relaxes is arranged in a mutually vertical manner.

In order to easy to assembly, the inner chamber of housing 1 offers and is available for clamp 23, base 31 and postive stop baffle 24 and plugs Mounting groove 14, the bottom of housing 1 is further opened with being available for leg 22 and blocks the draw-in groove 13 set, when assembling, all parts Can be plugged in corresponding mounting groove 14, it is achieved Fast Installation；The base 31 of wire-clamping device 3 and postive stop baffle 24 Offset so that overall structure is the compactest, the height of binding post is greatly reduced, it is possible to be preferably applied to LED The wiring occasion of light fixture.

The connection terminal structure of the present embodiment is small and exquisite, it is compact to coordinate, it is possible to what it is such that binding post overall volume does is less, More conform to the application in LED lamp field；Secondly, have employed carrying object 2 and wire-clamping device 3 is separated from each other setting Structure so that carrying object 2 can use electric conductivity more copper material manufacture, and wire-clamping device 3 then can use bullet Property the material such as more preferable stainless steel make, both ensure that the electric property of binding post, improve again clamp effect and can By property；It addition, the clamp of the wire-clamping device 3 of the present embodiment relaxes, the direction of insertion of direction and wire is to be arranged in a mutually vertical manner , it is possible to avoid traditional clamp relax direction and guide direction of insertion when be arrangeding in parallel wire be easily pulled out or slip Problem, is effectively improved clamp reliability, prevents wire in the case of unexpected pullling from binding post from the problem extracted, Improve dependability and the security of product.
