Abstract

The invention relates to a vehicle insert. The vehicle insert comprises a plurality of metal terminals, a plurality of insulation blocks which are spaced and a plastic shell. The insulation blocks are arranged on the metal terminals through injection moulding, thus forming a terminal module; the plastic shell is arranged on the terminal module through injection moulding; the plastic shell comprises a bottom wall, a side wall which stretches upwards from the bottom wall convexly, and a containing space formed between the bottom wall and the side wall; and at least one insulation block is equipped with a clamping hook which projects upwards into the containing space. The insulation blocks are simple in structure; the slide blocks of the die are arranged conveniently and easily; therefore, the structure of the die can be simplified; the production process is stable; and the reject ratio can be reduced.

Description

Automobile-used inserts

Technical field

The present invention relates to a kind of automobile-used inserts, particularly relate to a kind of automobile-used inserts adopting post forming。

Background technology

Automobile-used inserts generally comprises plastic casing and the metal terminal being insert molded in plastic casing, plastic casing complicated structure, the mould structure needed is also very complicated, in forming process, terminal easily misplaces, therefore, the each manufacturer of industry associates employing post forming, refer to shown in Fig. 1 and Fig. 2, first time some collets B of injection mo(u)lding on metal terminal A, form a Terminals Die group C, realize the Primary Location of each metal terminal A, second time injection mo(u)lding plastic casing D on this terminal module C, the position making each metal terminal A is accurately positioned, but, two snap fit D1 are had inside plastic casing D, mould needs to arrange the slide block of correspondence, but the moving displacement of slide block is very limited, the snap fit D1 structural strength of molding is low。

Summary of the invention

It is an object of the invention to provide a kind of automobile-used inserts manufacturing simplicity。

For realizing object defined above, the present invention adopts the following technical scheme that a kind of automobile-used inserts, it includes some metal terminals, spaced apart some collets and a plastic casing, described collets are injected and molded on metal terminal, form a Terminals Die group, described plastic casing is injected and molded on this terminal module, described plastic casing includes diapire, upwards protrude out from diapire sidewall and be formed between diapire and sidewall and hold space, at least one collets have and upwards protrude in the snap fit holding space。

The automobile-used inserts of the present invention by first time injection mo(u)lding fastening forming on collets, the simple in construction of collets, the slide block of mould arranges conveniently, easily, is conducive to simplifying mould structure, stable production process, reduces fraction defective。

Fig. 2 is the three-dimensional exploded view of automobile-used inserts in prior art。

Fig. 3 is the three-dimensional exploded view of the automobile-used inserts of the present invention。

Detailed description of the invention

Refer to shown in Fig. 3, the automobile-used inserts of the present invention comprises some metal terminals 10, spaced apart some collets 20 and a plastic casing 30, collets 20 are first injected and molded on metal terminal 10, form a Terminals Die group, and collets 20 have two snap fits 22 protruding upward。Then, plastic casing 30 is injected and molded on this terminal module, and automobile-used inserts manufacture completes。Plastic casing 30 includes diapire 31, upwards protrude out from diapire 31 sidewall 32 and be formed between diapire 31 and sidewall 32 and hold space 33, holds space 33 and is used for housing other components and parts。Terminal module is positioned at diapire 31, and snap fit 22 protrudes into accommodation space 33, for other components and parts of buckle。

The automobile-used inserts of the present invention by first time injection mo(u)lding fastening forming on collets 20, the simple in construction of collets 20, the slide block of mould arranges conveniently, easily, is conducive to simplifying mould structure, stable production process, reduces fraction defective。

Although being example purpose, have been disclosed for the preferred embodiment of the present invention, but those of ordinary skill in the art is it will be appreciated that when without departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible。

Claims

1. an automobile-used inserts, it includes some metal terminals, spaced apart some collets and a plastic casing, described collets are injected and molded on metal terminal, form a Terminals Die group, described plastic casing is injected and molded on this terminal module, described plastic casing includes diapire, upwards protrude out from diapire sidewall and be formed between diapire and sidewall and hold space, it is characterised in that: at least one collets have and upwards protrude in the snap fit holding space。
