By using said program, binding post is put into after being molded as inserts in cavity, snap ring can also play anti-
The effect that only binding post is extracted so that binding post preferably links together with electric melting pipe fittings.
As an improvement of the present invention, described matrix end face is axially sequentially communicated towards threading hole offers threaded hole and circle
The major diameter in platform hole, the round platform hole is connected to threaded hole, and the path of the round platform hole is connected to threading hole, is set in the threaded hole
There is positioning bolt, detent ball is equipped in the round platform hole, the detent ball outer diameter is more than round platform hole path, the threaded hole
Interior that flexible part is abutted between positioning bolt and detent ball, the elastic component makes detent ball have towards threading hole direction
Mobile trend, the detent ball part are located in threading hole.
By using said program, resistance wire is compressed after passing through threading hole by detent ball under the action of the elastic member, is risen
To the effect of positioning so that resistance wire is connect more secured with binding post.
As an improvement of the present invention, the outer diameter of the conductive column is more than the outer diameter of matrix, the outer diameter of the conductive column
More than the outer diameter of snap ring, cascaded surface is formed between the conductive column and matrix, the threading axially bored line is located at the cascaded surface.
By using said program, cascaded surface can play the role of limit, and binding post is avoided excessively to be absorbed in electric melting pipe fittings
It is interior；After binding post is connect by injection molding with electric melting pipe fittings, threading hole will not be caused to be blocked completely by plastics, can mainly threaded
Plastics are formed below the median plane in hole, so that resistance wire is preferably contacted in threading hole upper side, it is ensured that resistance value can
By property, to ensure that conductive qualities of the binding post when being powered.
As an improvement of the present invention, the connection corner of the wrapping wire slot and threading hole is set as fillet.
By using said program, resistance wire can be attached on fillet in bending, reduced resistance wire and fractureed, improve dress
With efficiency.
In conclusion the invention has the advantages that：
Quickly resistance wire fixation can be wrapped on Wiring terminal of electric melting pipe by by hand, without other tools, and
It is connected firmly；Resistance wire can fully improve the contact area with matrix by wrapping wire slot, and to improve electric conductivity, snap ring is right
While resistance wire in wrapping wire slot is limited, also have the effect of anti-pull out after injection molding so that binding post and electric melting pipe fittings
What is connected is more secured.
