Description

The street lamp block terminal

Technical field

The utility model relates to a kind of street lamp block terminal, is meant the termination of this street lamp block terminal especially.

Background technology

In the past, traditional street lamp wire connection plate manufacturing process was simple, punched on an insulation board, installed fishbolt and nut, fixedly mounted two fuse holders more onboard, the terminal block of this kind structure, and in the practice of construction out of doors, it is complicated that installation procedure just seems.This technology makes the contacting section of terminal block and lead very little, and the structure of the unlimited exposed conveying appliance of terminal block, exposes to the sun and rain, in the course of time, the oxidation of the power supply connecting terminal of terminal block tends to cause the resistance value of contact to increase, electric conductivity variation, contact current become big, and voltage reduces serious.If ponding is stained with on the terminal block, accident such as also can cause line short, open circuit causes the street lamp can't operate as normal.In addition, the structure of opening wide exposed conveying appliance to operating street lamp rush to repair, maintenance work brought certain danger.

For this reason, people improve it, include box body, lid and be arranged on the interior termination of box body, described termination includes pedestal and is arranged on the interior binding clip of pedestal, wherein binding clip is made up of the binding post of fishbolt and an end face and fishbolt threaded engagement, lead is installed in the cavity volume of binding post, by the fishbolt screw tip it is clamped.Though this kind structure can solve the aforesaid drawbacks, but used termination generally with fishbolt directly to the mode of connection of lead cramping, this termination is in the process of installing, debug, calibrate, safeguarding, since fishbolt frequently to lead directly extruding can cause the damage of conductive line surfaces, heating is serious when big electric current passes through wiring point, cause the interface loose contact, and break down, and the simple threaded engagement of fishbolt and binding post, fishbolt is very easily because factor affecting such as vibrations, from getting loose, and cause the wiring collapse.

Summary of the invention

The utility model is in order to solve the weak point that above-mentioned prior art exists, the street lamp block terminal that provides a kind of fishbolt frequent operation also can not damage to lead, and it is reasonable in design, and is simple in structure, is electrically connected reliability, tightness height.

For achieving the above object, the utility model adopts following scheme: a kind of street lamp block terminal, include box body, lid and be arranged on termination in the box body, described termination includes pedestal and is arranged on binding clip on the pedestal, wherein binding clip is made up of with the binding post of a cavity volume and the fishbolt that is housed in the binding post threaded one end hole the inboard, also be equiped with the clamp body that is bent into U-shaped in the described binding clip, its U-shaped clamp body is in the cavity volume of binding post on one side, and inner surface is corresponding with the top of fishbolt screw rod, another side is in outside the cavity volume of binding post, and be connected on the fishbolt fishbolt and its formation compression fit.

The utility model further is set to: described U-shaped clamp body is on the outer one side of the cavity volume of binding post and offers draw-in groove, it is connected to the tail end of fishbolt screw rod, and the diameter of screw rod tail end and draw-in groove cooperation place is slightly less than the diameter of screw flight, constitutes the compression fit of fishbolt and clamp body thus.

Be provided with two binding clips in the described pedestal, binding clip and binding clip are sought leading to and are connect.

Described pedestal internal wiring folder connects by the fuse body conducting that is connected on the binding post.

The beneficial effects of the utility model are: the utility model is compared with original technology, by in the binding clip of street lamp block terminal, adding the clamp body, contact with lead by the clamp body, strengthened the lifting surface area of lead, weaken and be subjected to force intensity, avoided fishbolt directly to contact with lead, reduced the extent of damage of lead, can adapt to product frequently installs, debugging, calibration, the occasion of safeguarding, and good contact the between clamp body and the lead, reduced fault because of striking sparks appears in loose contact and lead is oxidized, and strain takes place along with the continuous increase of fishbolt moment of torsion in U-shaped clamp body, make fishbolt generate a constant clamping force, prevent clamp stud loose or dislocation voluntarily.It is reasonable in design, and is simple in structure, is electrically connected reliability, tightness height, thereby has ensured the useful life of street lamp block terminal.

Below in conjunction with embodiment and accompanying drawing the utility model is further specified.

Embodiment

As shown in Figures 1 to 4, the utility model embodiment adopts a kind of street lamp block terminal, include box body 1, lid 2 and be arranged on the termination 3 of four same model in the box body 1, termination 3 numbers of installing in the box body 1 can be according to the different demands of user by factory settings, described termination 3 includes pedestal 4 and is arranged on binding clip 5 on the pedestal 4, wherein binding clip 5 is made up of binding post 51 and fishbolt 52, binding post 51 shows as a monomer members, framework with obvious quadrangular section, the binding post 51 inboard cavity volumes 511 that form, fishbolt 52 is installed in the screwed hole that connects on binding post 51 1 end faces, and pedestal 4 and binding post 51 are fixedly connected in the box body 1 by screw 9.Also be equiped with the clamp body 53 that is bent into U-shaped in the described binding clip 5, its U-shaped clamp body 53 is in the cavity volume interior 511 of binding post 51 on one side, and inner surface is corresponding with the top of fishbolt 52 screw rods 521, another side is in the cavity volume outer 511 of binding post 51, and be connected on the fishbolt 52, fishbolt 52 constitutes compression fit with one side that clamp body 53 is in binding post 51 cavity volumes interior 511.

The utility model embodiment further is set to, described U-shaped clamp body 53 is on the outer one side of the cavity volume 511 of binding post 51 and offers draw-in groove 531, it is connected to the tail end of fishbolt 521 screw rods 521, can follow fishbolt 52 moves axially, and the diameter of screw rod 52 tail ends and draw-in groove 531 cooperation places is slightly less than the diameter of screw rod 521 screw threads, it is inconsistent that U-shaped clamp body 53 is in the cavity volume 511 of binding post 51 outer there lateral surface and fishbolt 52 terminations 522 end faces, screw thread on medial surface and the screw rod 521 is inconsistent, constitutes the compression fit of fishbolt 52 and clamp body 53 thus.Be provided with two essentially

identical binding clips

5,6 of structure in the described pedestal 4, binding clip 5 is connected by fuse body 71 conductings that are connected in the fuse holder 7 on the

binding post

51,61 with binding clip 6, and binding

clip

5,6 also can be for being wholely set certainly.

The utility model is when installing wiring, open the lid 2 earlier, fishbolt 52 on each binding

clip

5,6 is unscrewed, thereby the mobile clamp body 53 that is connected on the fishbolt 52 that drives of fishbolt 52 moves, make clamp body 53 and binding post 51 cavity volumes 511 bottom spacings become big, the insulating barrier of lead 8 is peelled off, fill between cavity volume 511 interior clamp bodies 53 and cavity volume 511 bottoms, screw fishbolt 52, drive moving of clamp body 53, to clamp body 53 exerting pressure on one side, lead 8 is clamped in the cavity volume of binding post 51 by screw rod 521 tops.Because U-shaped clamp body 53 is inconsistent with screw rod 521 tops of fishbolt 52 on one side, termination 522 end faces of another side and fishbolt 52 are inconsistent, moment of torsion increase along with fishbolt 52, strain takes place in U-shaped clamp body 53, screw thread in fishbolt 52 screw threads and binding post 51 screwed holes is closely cooperated, can prevent from that fishbolt 52 from relaxing voluntarily to come off.
