Abstract

An embodiment of the utility model relates to an electric connector, which comprises a plastic body, terminals and a shielding shell. The terminal is embedded in the plastic body, the shielding shell is fastened at the front of the plastic body, a first plastic part and a second plastic part are oppositely fastened together to form the plastic body, each of the first plastic part and the second plastic part consists of a front plastic portion and a rear plastic portion, the front plastic portions are formed by means of injection molding, and secondary injection molding is realized after the terminals are assembled on the front plastic portions so as to form the rear plastic portions. The first plastic part and the second plastic part which are arranged in the same cavity mold by means of secondary injection molding are oppositely fastened to form the plastic body provided with the terminal in an embedded manner, forming process is simple, only the shielding shell is required to be fastened at the front of the plastic body in a follow-up procedure so as to form the electric connector, accordingly the electric connector is simpler and faster in assembly, the terminals are aligned correctly, and the quality of the electric connector is excellent and reliable.

Description

Electric connector

Technical field

The utility model relates to technical field of electric connectors, relates in particular to a kind of electric connector.

Background technology

Existing electric connector especially has the electric connector of many row's terminals, and its terminal assembling mode generally has two kinds of versions: a kind of is to be the plug-in unit that core rod injection mo(u)lding one is enclosed with terminal with the terminal earlier, then this plug-in unit is inserted in the insulating body; Another kind is that terminal is directly inserted in the insulating body.

The inventor is in implementing the utility model process, find that there is following technical problem at least in prior art: because electric connector is had relatively high expectations to the assembling of terminal, it is leading portion springing neatly, back segment will be fixed well, and terminal is more thin and the insulating body corresponding groove is also more narrower, above-mentioned dual mode all is difficult to make terminal to be aimed at and assembling puts in place, causes efficiency of assembling lower, the fraction defective height.

Summary of the invention

The utility model embodiment technical problem to be solved is, a kind of production simple and fast, terminal contraposition electric connector accurately is provided.

For solving the problems of the technologies described above, a kind of electric connector is provided, the shield shell that comprises the plastic cement body, is embedded at the intrinsic terminal of described plastic cement and is snapped in described plastic cement body portion, described plastic cement body is formed by first plastic parts and the second plastic parts make-up, the quadric injection mould moulding formed after described first plastic parts and second plastic parts included the preceding plastic cement portion of injection mo(u)lding and assemble terminal in the plastic cement portion described before back plastic cement portion.

Further, plastic cement portion comprises first groove of accommodating described terminal leading portion and second groove in the described terminal of clip stage casing before described.

Further, the groove width of described first groove is more than or equal to the corresponding width of described terminal leading portion, and the groove width of described second groove is more than or equal to the corresponding width in described terminal stage casing.

Further, described shield shell is a metal shell.

Further, described shield shell is provided with block button hole, correspondingly is respectively equipped with correspondence and snaps in fixture block in the described block button hole on described first plastic parts and second plastic parts.

Technique scheme has following beneficial effect at least: first plastic parts of quadric injection mould moulding and the second plastic parts make-up form the plastic cement body that is embedded with terminal in the mould of same chamber by adopting respectively, moulding process is simple, and follow-up need shield shell on plastic cement body portion buckle promptly forms electric connector, make the assembling simple and fast more of electric connector, and the terminal contraposition is accurate, and quality is superior reliable.

Fig. 2 is the decomposing schematic representation of electric connector shown in Figure 1.

Fig. 3 is the schematic diagram of the preceding plastic cement portion of electric connector shown in Figure 1.

Fig. 4 is the schematic diagram of the preceding plastic cement portion that sets terminal of electric connector shown in Figure 1.

Embodiment

Please refer to Fig. 1～Fig. 4, the electric connector of the utility model embodiment comprises plastic cement body 1, be embedded at the terminal 60 in the plastic cement body 1 and be snapped in the shield shell 30 of plastic cement body 1 front portion.

Plastic cement body 1 is fastened by first plastic parts 10 and second plastic parts 20 and forms, and first plastic parts 10 and second plastic parts 20 are the quadric injection mould moulding, that is: first plastic parts 10 quadric injection mould moulding in same die cavity; Second plastic parts 20 is quadric injection mould moulding in a corresponding die cavity also.

First plastic parts 10 and second plastic parts 20 include preceding plastic cement portion 40, back plastic cement portion 50 and be placed in before terminal 60 in plastic cement portion 40 and the back plastic cement portion 50.

Preceding plastic cement portion 40 is for injection mo(u)lding forms, and the one side surface is provided with first groove 41 and second groove 43 that is used to assemble terminal 60.

Back plastic cement portion 50 on the basis of preceding plastic cement portion 40 in the rear end of preceding plastic cement portion once more injection mo(u)lding form.

Terminal 60 is provided with many, and preceding, the stage casing of terminal 60 is positioned in the preceding plastic cement portion 40 and back segment is embedded at back plastic cement portion 50.Wherein, first groove 41 in the preceding plastic cement portion 40 is used to accommodate terminal 60 leading portions, and second groove 43 is used for the stage casing of clip terminal 60.Further, the groove width of first groove 41 is more than or equal to the corresponding width of terminal 60 leading portions, and the groove width of second groove 43 is more than or equal to the corresponding width in terminal 60 stage casings, thus the flexible springing of assurance terminal 60 leading portions, terminal 60 stage casings well secured is convenient to follow-up injection moulding and assembling work.

Shield shell 30 is a metal shell.Shield shell 30 1 ends are provided with two block button holes 31 up and down, correspondingly are respectively equipped with the fixture block 11 that correspondence snaps in block button hole 31 on first plastic parts 10 and second plastic parts 20.When shield shell 30 and plastic cement body 1 buckle, fixture block 11 correspondences snap in the block button hole 31.

The making flow process of the electric connector of the utility model embodiment is: 1, produce first plastic parts 10 and second plastic parts 20, particularly, the first preceding plastic cement portion 40 of injection mo(u)lding first plastic parts 10 and second plastic parts 20 in corresponding die cavity respectively, as shown in Figure 3; Then, assembling terminal 60 promptly as shown in Figure 4, is put into first groove 41 of preceding plastic cement portion 40 with terminal 60 leading portion correspondences, and the stage casing of terminal 60 is fixed in second groove 43; At last, the preceding plastic cement portion 40 that is assembled with terminal 60 still is retained in the die cavity, carries out the quadric injection mould moulding and forms back plastic cement portion 50 at an end of preceding plastic cement portion 40 corresponding second grooves 43, and it is good fixing to guarantee to make the back segment of terminal 60 embed back plastic cement portion 50; 2, first plastic parts 10 and second plastic parts 20 are carried out make-up formation plastic cement body 1; 3, load onto shield shell 30 in the front portion of plastic cement body 1.

The above is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
