Abstract

The utility model relates to an electric connector, which comprises an inner insulator, a plurality of conductive terminals inlaid in the inner insulator, a metal shell body which covers outside the inner insulator, and an outer insulator wrapped on the circumferential side of the metal shell body. The utility model is characterized in that the outer insulator is integrally molded in a jet way, and a clamping device is arranged in the outer insulator. When the inner insulator, the conductive terminals and the metal shell body of the electric connector are well assembled, the outer insulator is sheathed on the assembled electric connector through automatic assembling tools and clamped and buckled with corresponding elements on the metal shell body through the clamping device arranged on the outer insulator, and thus, the outer insulator is quickly and firmly assembled on the electric connector.

Description

Electric connector

The utility model is a kind of electric connector, refers in particular to a kind of electric connector of being convenient to automated production.

The electric connector relevant with this case sees also Taiwan patent application the 82109498th, 83107038 and No. 83207804, wherein the electric connector that is disclosed for No. 82109498 sees also shown in Figure 1, it comprises interior insulator 6, be embedded at several conducting terminals (not label) in the insulator 6 in this, cable 7 that is connected with these conducting terminals and part are coated on the outer insulator of described interior insulator 6 and cable 7 all sides, wherein outer insulator comprises that but buckle is first housing 91 and second housing 92 of one, and the buckle of this two housing is by being reached by the metal clips 8 that is embedded in first housing 91.The extending end 81 of this metal clips 8 has inwardly protruded out buckling piece 811, and second housing 92 is provided with holding hole 921, after insulator 6, conducting terminal and cable 7 assemble in advance in described, by other instruments with these first, second housing 91,92 mutual buckles.At this moment, the buckling piece 811 of metal clips 8 is fastened in the holding hole 921 set on second housing 92 just, thereby two housings is firmly combined, and promptly finishes the assembling of whole electric connector.But the shortcoming of existing design is, the Hou number of assembling steps of this electric connector is that the assembling of first, second housing of outer insulator is to cross by other instrument to finish, so has increased production cost, is unfavorable for that automation produces fast.

It is a kind of easy to assembly that the purpose of this utility model is to provide, and can improve the electric connector of automated production efficient.

The purpose of this utility model is achieved in that this electric connector includes interior insulator, be embedded at several conducting terminals in the insulator in this, the cover cap metal shell outside the insulator and part in this are coated on the outer insulator of this metal shell week side, it is characterized in that: metal shell is provided with retaining component, and outer insulator is the one ejection formation, form the receiving space of a hollow, and its inside be provided with can with holding unit on the metal shell holding unit of buckle mutually, interior insulator when electric connector, after conducting terminal and metal shell assemble, rely on automatic assembly tool that outer insulator directly is nested with on the electric connector that this part assembles, by holding unit set on the outer insulator can with the counter element of electric connector mutually

Advantage of the present utility model is: easy to assembly, can improve automated production efficient.

Below in conjunction with drawings and Examples to the utility model further instruction.

Fig. 1 is the stereogram after the existing electric connector exploded.

Fig. 2 is the three-dimensional exploded view of the utility model electric connector.

Fig. 3 is the stereogram after the local combination of the utility model electric connector.

Fig. 4 is the partial sectional view after the utility model electric connector combination, and it shows outer insulator and the metal shell state of buckle mutually.

See also shown in Figure 2, the utility model electric connector includes interior insulator 1, be embedded at the outer insulator 4 that several conducting terminals 2 in insulator 1, cover cap in this metal shell insulator 1 outside 3 and part in this are coated on these insulation shell 3 all sides, after these elements are assembled can with the electric connector that docks

Please consult Fig. 2 and shown in Figure 3 simultaneously, interior insulator 1 includes several vertically and be arranged in parallel and be used for accommodating the terminal containing slot 11 of corresponding conducting terminal 2.Each conducting terminal 2 is a longitudinal bodies, comprise the junction surface 21 and the docking section 22 that are contained in described terminal containing slot 11 two ends respectively, connecting mutually with the terminal (not shown) of cable and butt connector respectively, thereby constitute electrically conducting between different electronic installations.In addition, metal shell 3 is a two-piece construction, include first housing 31 and second housing 32 of buckle mutually, this first housing 31 can be wherein ccontaining for interior insulator 1, then being provided with on second housing 32 can be for deduct retaining component on it of the projection 422 of outer insulator 4 (Fig. 4 with reference to), this retaining component is holding hole 321 in present embodiment, in order to being one with the firm winding of whole electric connector.And correspondence is provided with bayonet unit on the two

housings

31,32, in the present embodiment, this bayonet unit is to be separately positioned on the buckling body 310 of first housing 31 and to be arranged on block button hole 320 on second housing 32, in order to being one with these first,

second housing

31,32 firm windings.

Please cooperate and consult Fig. 3 and shown in Figure 4, the outer insulator 4 of the utility model electric connector comprises convergent shape cable plug termination end 41 and the host side 42 that is connected with its one, wherein cable plug termination end 41 can plug wherein for the cable (not label) that connects electronic installation, and host side 42 is a rectangle perisporium, the inboard of this perisporium surrounds a receiving space 421, and this receiving space 421 can partly be accommodated interior insulator 1, conducting terminal 2 and the metal shell 3 after the described combination.In addition, holding hole 321 positions of corresponding described second housing 32 are provided with projection 422 on the narrower relative inner face of this perisporium two, with the holding hole 321 corresponding buckles of described second housing 32.

Please consult Fig. 2 simultaneously to shown in Figure 4, during assembling, earlier several conducting terminals 2 are inserted in the terminal containing slot 11 of interior insulator 1 respectively, then first housing 31 is sheathed on interior insulator 1 outside of conducting terminal 2, again with second housing, 32 cover caps in this on insulator 1, wherein projection 422 extend in the holding hole 321 of second housing 32 and with its buckle mutually, thereby with this outer insulator 4 be coated with in the metal shell 3 fast firm windings of insulator 1 be one.

Because the outer insulator of the utility model electric connector can be by behind the injection molding equipment Unitary injection formed To electric connector, will be conducive to like this design production of mould and whole through the direct winding of assembly process The assembling work of body. And outer insulator is to make respectively upper and lower with slide block by mould in the existing design Two parts, again by by other instruments this upper and lower two parts sealed junction being combined, therefore, this reality Compare with novel and existing design, have the advantage of being convenient to assemble and be conducive to rapid automatized production.
