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 such as catalyst, chopper etc., coil is typically wound around on coil rack, coil
One end forms the first binding post with the first conductive metal sheet electrical connection, the first screw lock on the first conductive metal sheet,
And the other end of coil and the second conductive metal sheet are electrically connected, the second screw lock forms second on the second conductive metal sheet
Binding post.
First screw, in assembling, is first screwed in the first conducting metal by described winding wiring terminal containing cavity structure respectively
Plate, the second screw is screwed in the second metallic plate；Then by the first screw and the first conductive metal sheet, and the second screw and second
Metallic plate, in overall insertion coil rack；Unclamp the first screw and the second screw more respectively, carry out coil-winding, otherwise easily
Kinking；During detection, again the first screw and the second screw need to be screwed off, contact with probe and detected.Therefore, prior art coil
During binding post containing cavity Standard, need stubborn first screw repeatedly and the second screw, assembly technology is complex, and cannot
Realize Automated assembly.
For preventing dust from entering winding wiring terminal containing cavity structure, improve degree of protection, generally in coil rack simultaneously
After loading the body, on the body, so that unitary plastic part is excessive, structure is more multiple for special setting winding wiring terminal protective cover
Miscellaneous, and increase cost.
Content of the invention
It is an object of the invention to provide a kind of winding wiring terminal containing cavity structure, it is applied to Automated assembly, fall
Low production cost；Simple for structure, reliable it is not necessary to special winding wiring terminal protective cover.
For reaching above-mentioned purpose, the 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；Conducting metal
Plate is arranged in containing cavity, is connected with coil electric, forms position limiting structure, so that screw can be opened from containing cavity sidepiece in containing cavity
Mouth loads without coming off, and accommodating top of chamber forms the through hole with IP2X degree of protection, and the aperture of through hole is slightly larger than head of screw
Portion's 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 the wall of containing cavity side, flexure strip and side wall
Between formed aperture efficiency screw head little, flexure strip resilient clamp is in screw head.
Further, described flexure strip one end and containing cavity side wall are integrally formed, and flexure strip is by containing cavity lateral in containing cavity
Side mouth is obliquely installed, and the flexure strip other end forms resilient clamp mouth with containing cavity, and forms guide face in the flexure strip other end,
Screw enters, by resilient clamp mouth, the grasping part that flexure strip is surrounded with containing cavity side wall by guide face.
Further, described position limiting structure is boss, and boss is shaped on the wall of containing cavity side, shape between boss and side wall
The aperture efficiency screw head becoming is little, and boss resilient clamp is in screw head.
Further, described boss is set to symmetrical two, and the distance between two boss are less than screw head.
Further, two ribs are formed in containing cavity bottom, the distance between two ribs are less than the external diameter of screw, screw embeds
In two ribs.
Further, described containing cavity upper end is integrally formed protective cover.
Further, the containing cavity of multiple side mouth is formed on coil rack；Conducting metal is installed in each containing cavity
Plate, conductive metal sheet is connected with coil electric, and screw is placed in containing cavity by side mouth, forms restriction nail de- in containing cavity
The position limiting structure falling, accommodating top of chamber forms the through hole with IP2X degree of protection, and the aperture of through hole is slightly larger than outside screw head
Footpath；Containing cavity front side wall forms fluting, and conductive metal sheet is exposed；Air insulation area is set between multiple containing cavities.
After such scheme, the present invention, in assembling, first will load in coil rack, then after conductive metal sheet kinking
By mechanical hand, screw is loaded containing cavity from containing cavity side mouth, now, the position limiting structure in containing cavity limits screw
Come off；Finally by screw lock on conductive metal sheet, complete to assemble.
The present invention can first coil be wrapped on conductive metal sheet, be then fitted in coil rack, now need not pacify
Cartridge screw, arranges position limiting structure in containing cavity so that screw can load without coming off from containing cavity side mouth, and existing
Technology must first screw be arranged on conductive metal sheet, just can be assembled in coil rack, otherwise, toner screw；Conductive gold
After genus plate is assembled to coil rack, screw need to be unclamped and carry out kinking, otherwise, screw can be wound around line；After the completion of kinking, spiral shell need to be tightened
Nail to detect, need to repeatedly tighten or unclamp screw, and connection terminal structure of the present invention assembling when, need not repeatedly tighten or
Unclamp screw, therefore, the present invention can realize Automated assembly completely, and assembly technology is relatively simple, save production cost.
Meanwhile, conductive metal sheet end exposed so that detection when, probe directly can be contacted with electric metal plate and be examined
Survey, detection is more convenient.
In screw and embedded two ribs, lax such that it is able to prevent screw from occurring.Meanwhile, described accommodating top of chamber one becomes
Type and form protective cover so that protective cover need not be separately provided, structure is more simply compact, and degree of protection can reach
IP20.
