Abstract
A kind of electric melting pipe fittings binding post, including binding post body, connection end and fastening end are provided with binding post body, the fastening end outer surface is enclosed with raw material, the bottom of fastening end is provided with a Y type opening, the end of Y type openings is provided with cylindrical cavity, the diameter of the cylindrical cavity is more than the external diameter of corresponding resistance wire, the resistance wire is interference fit with cylindrical cavity, the design of Y type openings improves contact and degree of being completely embedded of the resistance wire with binding post in electric melting pipe fittings, it is effective avoid resistance wire and binding post because connection loosens and caused by product power off the problem of, improve the quality of electric melting pipe fittings.
Description
Technical field
A kind of binding post is the utility model is related to, more particularly, to a kind of electric melting pipe fittings binding post.
Background technology
Mainly include a hollow main pipe body for a complete electric melting pipe fittings, be partly embedded in pipe fitting master
Binding post, some resistance wires on body.Electric melting pipe fittings in use are to be abutted against terminal with the joint of electro-fusion welding machine to be connected, and are realized
It is powered, but the stability that binding post is connected with resistance wire, fastness, is that to determine whether a product can use important
Factor, not perfect enough for the technology of this respect in the prior art, the utility model proposes a kind of new for problem above
Solution.
Utility model content
The purpose of this utility model is to provide a kind of simple to operate, and fault rate is low, and fastness is high, the high one kind of stability
Electric melting pipe fittings binding post.
In order to solve the above technical problems, the utility model provides a kind of electric melting pipe fittings binding post, including binding post body,
Connection end and fastening end are provided with binding post body, the fastening end outer surface is enclosed with raw material, and the bottom of fastening end is provided with
One Y type opening, the end of Y type openings are provided with cylindrical cavity, and the diameter of the cylindrical cavity is more than corresponding electricity
The external diameter of silk is hindered, the resistance wire is interference fit with cylindrical cavity.
In order to preferably use binding post body, the utility model, which improves, to be had, and the external diameter in the fastening end centre position is small
External diameter in fastening end both ends.
In order to preferably use cylindrical cavity, the utility model, which improves, to be had, and the diameter ratio of the cylindrical cavity is relative
The big 0.1mm of external diameter for the resistance wire answered.
The beneficial effects of the utility model are：The utility model is novel in design, simple in construction, and the design of Y type openings improves
Contact and degree of being completely embedded of the resistance wire with binding post in electric melting pipe fittings, resistance wire and binding post are effectively avoided because of connection
Loosen and caused by product the problem of powering off, improve the quality of electric melting pipe fittings, the external diameter in fastening end centre position is less than fastening
Hold the design of the external diameter at both ends effectively to serve the effect of anti-pull-off, ensure that positioning of the whole binding post inside product is steady
It is fixed.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of electric melting pipe fittings binding post of the present utility model；
Label declaration：1- binding post bodies；2- connection ends；3- fastening ends；4-Y type openings；5- cylindrical cavities.
Embodiment
To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Referring to the drawings 1, the utility model provides a kind of electric melting pipe fittings binding post, including binding post body 1, binding post sheet
Connection end 2 and fastening end 3 are provided with body, the outer surface of fastening end 3 is enclosed with raw material, and the bottom of fastening end is provided with a Y
Type opening 4, the end of Y types opening 4 are provided with cylindrical cavity 5, and the diameter of the cylindrical cavity 5 is more than corresponding resistance
The external diameter of silk, the resistance wire are interference fit with cylindrical cavity 5.
In order to preferably use binding post body, the external diameter in the centre position of fastening end 3 is less than the outer of the both ends of fastening end 3
Footpath.In order to preferably use cylindrical cavity, the diameter of the cylindrical cavity 5 is bigger than the external diameter of corresponding resistance wire
0.1mm。
The connection end 2 is not wrapped up by raw material, and fastening end 3 is wrapped in the raw material in product, the upper shed of Y types opening 4
Starting outer diameter is 4mm, depth 1.2mm, why is designed to Y types opening 4 primarily to ensureing that resistance wire can be smoothly past
The inside is inserted, and the end of Y types opening 4 is the cylindrical cavity 5 that a depth is 3.5mm, in the utility model among fastening end 3
The external diameter of position is 3.6mm, and the external diameter at the both ends of fastening end 3 is 6mm.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
