Currently used Wiring terminal of electric melting pipe, particular with the Wiring terminal of electric melting pipe of liner, being substantially to connect Terminal is as insert injection moulding in interior lining, and the heating wire for then completing coiling is perforated, and is compressed with red copper bar, this not only process it is numerous It is trivial, while because injection pressure is excessive, easily generation binding post is crooked, broken string so is also easy to produce when carrying out protective layer injection, from And cause waste product.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of simple in construction, operation and easily, beneficial to raising produced The Wiring terminal of electric melting pipe of efficiency and yield rate.

In order to solve the above technical problems, the technical solution of the utility model is：Wiring terminal of electric melting pipe, for liner Electric melting pipe fittings；It is provided with the lateral wall of the liner on binding post slot, the cell wall of the binding post slot from notch end Leaded breach is opened up to trench bottom extension；The Wiring terminal of electric melting pipe includes the conductive pole of upper end and the matrix of lower end, institute Stating matrix includes being used to insert in the binding post slot realizing indent on the locating dowel of positioning, the periphery wall of the locating dowel It is provided with winding slot.

As preferred technical scheme, the 0.5~1mm of bottom of the slotting position of the winding slot apart from the locating dowel.

As preferred technical scheme, the section of the locating dowel is rounded, square or rhombus, naturally it is also possible to use it His arbitrary shape, to realize positioning function.

As preferred technical scheme, the rugosity of the conductive pole is less than the rugosity of described matrix, so that the electricity Fusion tube part binding post constitutes up-thin-low-thick structure.

As preferred technical scheme, the conductive pole and described matrix are integrally formed using brass material.

By adopting the above-described technical solution, the utility model has the advantages that：Twined by using by heating wire It is wound in winding slot, is then pressed into rotation in electric melting pipe fittings liner binding post slot and tenses, it is to avoid conventional open threading is clamped The troublesome operation such as sub-folder is tight, has simplified heating wire winding process, has not only reduced labor strength, improved production efficiency, Avoid the decrease in yield problem for bringing binding post directly as insert injection moulding simultaneously；The binding post is easy to operate, positioning Firmly, the raising of yield rate is conducive to.

Embodiment

With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only by saying Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim Scope.

As shown in Figures 1 to 4, Wiring terminal of electric melting pipe, for the electric melting pipe fittings with liner 1；The outside of the liner 1 The extension from notch end to trench bottom is provided with binding post slot 2, the cell wall of the binding post slot 2 on wall and opens up leaded lack Mouth 3；The Wiring terminal of electric melting pipe is integrally formed using brass material, including the conductive pole 4 of upper end and lower end it is integrally formed Matrix 5, the rugosity of the conductive pole 4 is less than the rugosity of described matrix 5, so that Wiring terminal of electric melting pipe composition is upper thin Lower coarse-texture, not only firm position, and manually rotate and tighten when facilitating wiring.

Wherein, described matrix 5 includes being used to insert to realize the locating dowel 51 of positioning in the binding post slot 2, described Indent is provided with winding slot 52 on the periphery wall of locating dowel 51.The slotting position of the winding slot 52 is preferably apart from the locating dowel 0.5~1mm of bottom, compression heating wire is securely wound during wiring to facilitate.

In addition, the section of the locating dowel 51 can use circular, square or rhombus, naturally it is also possible to any using other Shape, to realize positioning function.

Referring to figs. 2 and 3 heating wire mode of connection is as follows：After the production of liner 1 is finished, by the one ends wound of heating wire 6 in base On the winding slot 52 of body 5, heating wire 6 is introduced in binding post slot 2 by the lead breach 3 on binding post slot 2, will be wound The insertion binding post of matrix 5 slot 2 of upper heating wire is positioned, and then heating wire 6 is wrapped on liner 1, and being repeated to the other end will Heating wire 6 is introduced binding post on winding slot 52, by the lead breach 3 on binding post slot 2 and inserted by the one ends wound of heating wire 6 In groove 2, the matrix 5 for winding upper heating wire is inserted into binding post slot 2 and positioned, and conductive pole 4 is turned with hand, heating wire 6 is drawn Tightly.So by method for implantation after binding post, heating wire winding process is simplified, labor intensity is reduced, improved production effect Rate, simultaneously because binding post and the non-immovable fitting of liner, therefore finished product rate when improving injection.

The schematical embodiment of the utility model is the foregoing is only, model of the present utility model is not limited to Enclose.Any those skilled in the art, the made equivalent change on the premise of design of the present utility model and principle is not departed from Change and change, the scope of the utility model protection all should be belonged to.
