Description
Technical field
The present invention relates to a kind of winding wiring terminal containing cavity structure.
Background technology
In prior art, some electrical appliances are as contactor, circuit breaker etc., coil is conventionally on coil rack, one end of coil and the electrical connection of the first conductive metal sheet, the first screw lock forms the first binding post on the first conductive metal sheet, and the other end of coil and the electrical connection of the second conductive metal sheet, the second screw lock forms the second binding post on the second conductive metal sheet.
Described winding wiring terminal containing cavity structure, in the time of assembling, first screws in the first conductive metal sheet by the first screw respectively, and the second screw is screwed in to the second metallic plate; Then by the first screw and the first conductive metal sheet, and the second screw and the second metallic plate, entirety is inserted in coil rack; Unclamp respectively again the first screw and the second screw, carry out coil-winding, otherwise easy kinking; When detection, need again the first screw and the second screw be screwed off, contact and detect with probe.Therefore, when prior art winding wiring terminal containing cavity Standard, need stubborn the first screw and the second screw repeatedly, assembly technology is comparatively complicated, and cannot realize automation assembling.
For preventing that dust from entering winding wiring terminal containing cavity structure, improve degree of protection simultaneously, conventionally pack into after the body at coil rack, winding wiring terminal protective cover is set specially on the body, make unitary plastic part too much, structure is comparatively complicated, and increases cost.
Summary of the invention
The object of the present invention is to provide a kind of winding wiring terminal containing cavity structure, it is applicable to automation assembling, reduces production costs; Simple for structure, reliable, do not need special winding wiring terminal protective cover.
For reaching above-mentioned purpose, solution of the present invention is:
A kind of winding wiring terminal containing cavity structure forms the containing cavity of side mouth on coil rack; Conductive metal sheet is arranged in containing cavity, be connected with coil electric, in containing cavity, form position limiting structure, make screw pack into and can not come off from containing cavity side mouth, the through hole with IP2X degree of protection is formed on containing cavity top, and the aperture of through hole is slightly larger than screw head external diameter; Containing cavity front side wall forms fluting, and conductive metal sheet is exposed.
Further, described position limiting structure is flexure strip, and flexure strip is shaped on containing cavity sidewall, and the aperture efficiency screw head forming between flexure strip and sidewall is little, and flexure strip resilient clamp is at screw head.
Further, described flexure strip one end and containing cavity sidewall are one-body molded, flexure strip is obliquely installed by side direction containing cavity side mouth in containing cavity, the flexure strip other end and containing cavity form resilient clamp mouth, and form guide face at the flexure strip other end, screw enters by resilient clamp mouth the grasping part that flexure strip and containing cavity sidewall surround by guide face.
Further, described position limiting structure is boss, and boss is shaped on containing cavity sidewall, and the aperture efficiency screw head forming between boss and sidewall is little, and boss resilient clamp is at screw head.
Further, described boss is set to two of symmetry, and the distance between two boss is less than screw head.
Further, form two ribs in containing cavity bottom, the distance between two ribs is less than the external diameter of screw, and screw embeds in two ribs.
Further, the one-body molded protective cover in described containing cavity upper end.
Further, on coil rack, form the containing cavity of multiple side mouth; In each containing cavity, conductive metal sheet is installed, conductive metal sheet is connected with coil electric, screw is placed in containing cavity by side mouth, in containing cavity, form the position limiting structure that restriction nail comes off, the through hole with IP2X degree of protection is formed on containing cavity top, and the aperture of through hole is slightly larger than screw head external diameter; Containing cavity front side wall forms fluting, and conductive metal sheet is exposed; Air insulation district is set between multiple containing cavities.
Adopt after such scheme, the present invention, in the time of assembling, first will pack in coil rack after conductive metal sheet kinking, then by manipulator, screw is packed into containing cavity from containing cavity side mouth, now, the position limiting structure restriction toner screw in containing cavity; Finally by screw lock on conductive metal sheet, complete assembling.
The present invention can be first by coil winding on conductive metal sheet, then be assembled in coil rack, now without mounting screw, position limiting structure is set in containing cavity, make screw to pack into and can not come off from containing cavity side mouth, and prior art must first be arranged on screw on conductive metal sheet, just can be assembled in coil rack, otherwise, toner screw; Conductive metal sheet is assembled to after coil rack, and need unclamp screw and carry out kinking, otherwise, screw meeting wrap wire; After kinking completes, screw need be tightened to detect, screw need be repeatedly tightened or unclamp, and when connection terminal structure of the present invention assembling, without repeatedly tightening or unclamping screw, therefore, the present invention can realize automation assembling completely, and assembly technology is comparatively simple, saves production cost.
Meanwhile, conductive metal sheet end is exposed, and while making to detect, probe can directly contact and detect with electric metal plate, detects more convenient.
In screw and embedding two ribs, thereby it is lax to prevent that screw from occurring.Meanwhile, described containing cavity top is one-body molded and form protective cover, make without protective cover is set separately, and the more simple compactness of structure, and degree of protection can reach IP20.
