Abstract

The utility model relates to a connector, which comprises a first plastic half shell, terminals, elastic hooks, a second plastic half shell and a metal shell, wherein the first plastic half shell is formed by means of injection molding, the terminals and the elastic hooks are embedded onto the first plastic half shell, the second plastic half shell is integrally connected with the first plastic half shell by taking the first plastic half shell embedded with the terminals and the elastic hooks as a mould core by means of secondary injection molding, the first plastic half shell and the second plastic half shell jointly form an integrated plastic shell wrapping the terminals and the elastic hooks, and the metal shell is sleeved outside the plastic shell. By means of a two-time injection molding structure, the terminals can be well positioned when secondary injection molding is performed, deviation can be avoided, and the terminals can be protected from being damaged, so that qualified rate of finished products is effectively guaranteed.

Description

Connector

Technical field

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

Background technology

Connector generally includes glue core that independent respectively moulding makes, is embedded in terminal, plastic cement shell and metal-back on the glue core.Its traditional packaging technology is: terminal is embedded on the glue core, in the plastic cement shell of packing into then, externally puts metal-back at last again.This traditional connector construction has caused its assembling loaded down with trivial details, and especially terminal is all more tiny, and it is unstable to occur the location when it is embedded on the glue core easily, and the finished product after causing assembling can not be realized good conducting, and defect rate is high.

Industry also has a kind of connector, and its glue core and terminal fuse through injection molding, and then the assembly of glue core and terminal is inserted in the plastic cement shell.Because the glue core just wraps the stage casing of terminal, is manual operation being inserted into the plastic cement shell, still exist contraposition to be forbidden and the situation of damage terminal.

The utility model content

The utility model embodiment technical problem to be solved is, a kind of connector is provided, and it makes simple, and can avoid the inaccurate defective of terminal position.

For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of connector comprises:

First plastic cement, half shell of injection mo(u)lding;

The terminal and the bullet that are embedded on said first plastic cement, half shell collude;

To be embedded with first plastic cement, half shell that terminal and bullet collude is second plastic cement, half shell that core rod fuses through quadric injection mould moulding and first plastic cement, half shell, and said first plastic cement, half shell and second plastic cement, half shell constitute integral type jointly and be enclosed with the plastic cement shell that terminal and bullet collude; And

Be sheathed on the outside metal-back of plastic cement shell.

Further, there are a plurality of confession terminals that laterally arrange and bullet to collude on said first plastic cement, half shell and are embedded in the caulking groove in it.

Further, said terminal has a plurality of, and said a plurality of terminals are embedded in the caulking groove at first plastic cement, half shell middle part, and bullet to collude be two, be embedded at first plastic cement, half shell and lean in the caulking groove of both sides.

Further, said bullet collude have pass plastic cement shell and metal-back and stretch out collude the portion of button.

Further, all expose from the rear end of plastic cement shell said terminal and the bullet rear end of colluding.

Said plastic cement shell is provided with the fixture block that is clasped with metal-back, correspondingly on metal-back, is provided with block button hole.

Through adopting technique scheme; The utility model has following beneficial effect at least: the utility model is through adopting quadric injection mould formula structure, and terminal can be located when quadric injection mould preferably, the phenomenon that can not occur squinting; And can not damage terminal, thereby effectively guaranteed product qualified rate.

Embodiment

Please refer to an embodiment of the utility model of Fig. 1 ~ shown in Figure 4, the utility model provides a kind of connector, comprising:

First plastic cement, half shell 10 of injection mo(u)lding;

The terminal 2 and the bullet that are embedded on said first plastic cement, half shell 10 collude 3;

To collude 3 first plastic cement, half shell 10 be second plastic cement, half shell 12 that core rod fuses through quadric injection mould moulding and first plastic cement, half shell 10 to be embedded with terminal 2 and bullet, and said first plastic cement, half shell 10 and second plastic cement, half shell 12 be common to be constituted integral types and be enclosed with the plastic cement shell 1 that terminal and bullet collude; And

Be sheathed on the metal-back 4 of plastic cement shell 1 outside.

In the specific implementation; Collude 3 for ease of being embedded said terminal 2 and bullet; Usually on said first plastic cement, half shell 10, have a plurality of confession terminals 2 that laterally arrange and bullet to collude 3 caulking grooves 11 that are embedded in it, the bullet that said caulking groove 11 comprises the terminal groove 110 that is positioned at first plastic cement, half shell, 10 middle parts and is positioned at first plastic cement, half shell, 10 both sides colludes groove 112.Correspondingly, connector all has a plurality of terminals 2 usually, and said a plurality of terminals 2 are embedded at and are positioned at terminal groove 110, and bullet colludes 3 and is typically provided with two, is embedded at first plastic cement, half shell 10 respectively and leans on the bullet of both sides to collude in the groove 112.Said bullet colludes 3 and has the portion of button 30 of colluding of passing plastic cement shell 1 and metal-back 4 and stretching out, and cooperates so that when pegging graft with corresponding connector, collude button.And for ease of connector is realized being electrically connected with corresponding lead or circuit board, said terminal 2 and bullet collude 3 rear end and all expose from the rear end of plastic cement shell 1.

For stably metal-back 4 being assembled on the plastic cement shell 1, and on said plastic cement shell 1, be provided with fixture block 13, and metal-back 4 is provided with fixture block 13 and realizes the block button hole 40 that is clasped.

When making the utility model connector, first injection mo(u)lding first plastic cement half shell 10 need not first plastic cement, half shell 10 is taken out the injection moulding die cavity this moment; Then terminal 2 and bullet being colluded 3 all embeds in the caulking groove 100 of first plastic cement, half shell 10; To collude 3 first plastic cement, half shell 10 be that core rod molds second plastic cement, half shell 12 through quadric injection mould to be embedded with terminal 2 and bullet then, and at this moment, first plastic cement, half shell 10 and second plastic cement, half shell 12 be common to constitute that integral types are enclosed with terminal 2 and bullet colludes 3 plastic cement shell 1; At last, plastic cement shell 1 is taken out in die cavity, put metal-back 4 again and get final product.
