Description

Electric connector

Technical field

The utility model is a kind of electric connector, but refers to a kind of electric connector of transmission of electric signals especially.

Background technology

Along with all types of electronic products are more and more universal, the demand of the necessary connecting elements-electric connector between the electronic product (electrical connector) is also increasing.More and more frivolous along with the external form of electronic product in addition, can take, the volume of electric connector is also accordingly more and more littler, so the manufacture difficulty of electric connector also improves accordingly.In order to produce the less and enough electric connectors of bond strength each element of volume, electric connector has adopted the mode of a kind of mould internal shaping (insertmolding) to make, and is described in detail as follows:

Electric connector generally has main three elements: glue core body, conducting terminal and metal shell.Conducting terminal and metal shell complete earlier respectively, then both are positioned in the mould of an injection molding, at last the material injection (injecting) of glue core body are gone in this mould.Glue core body can form in the mould, and partial volume conducting terminal and metal shell is embedded in the glue core body.

This kind mode can allow the bond strength of each element enough really, but still have a little disappearances, this disappearance is: the part end face of conducting terminal front end need be exposed to the glue core, and this is external, conducting terminal contact for the butt joint electric connector, but because the factors such as scale error of mould, during the part end face of conducting terminal front end and can be covered, cause it can't reach its function by glue core body.When the material of glue core body was injected in the mould in addition, it had certain pressures (injectingpressure) of penetrating, if it is improper to penetrate pressure-controlled, when material impact arrives metal shell, easily metal shell was hit to distortion.

Above-mentioned disappearance all can cause the fine ratio of product of electric connector significantly to reduce, the real genus unfortunately.

Therefore so the above-mentioned disappearance of the present utility model people's thoughts can be improved, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance.

The utility model content

Main purpose of the present utility model is to provide a kind of electric connector, and it is when the mould internal shaping, and conducting terminal can not covered by the material of unexpected glue core body.

For reaching above-mentioned purpose, the utility model proposes a kind of electric connector, comprise: a glue core body, it has a main body, a hyoplastron, most embedded grooves and most protruding walls, this hyoplastron is convexly set in the front side of this main body, those embedded grooves are arranged with the end face in this hyoplastron, and those protruding walls are convexly set in the end face of this hyoplastron; A most conducting terminal, it respectively has a contact chip, and embeds a sheet and a bonding pad, this embedding sheet is arranged at the front side of this contact chip, this bonding pad is arranged at the rear side of this contact chip, this contact chip is fixed in the end face of this hyoplastron, this bonding pad is fixed in the end face of this main body, and this embedding sheet stretches in this embedded groove, has one between this contact chip and this protruding wall at interval; And a metal shell, it is fixed on this glue core body.

The utlity model has following beneficial effect: owing to respectively have one between the contact chip of those conducting terminals and those the protruding walls at interval, in order to reach such design, therefore during the mould internal shaping employed mould will have one corresponding those at interval shape and the convex structure of position, when making the material of this glue core body in injecting mould, it is mobile toward the end face of contact chip that this convex structure is blocked material, so the end face of contact chip can not covered by the material of unexpected glue core body.

For enabling further to understand feature of the present utility model and technology contents, see also following relevant detailed description of the present utility model and accompanying drawing, yet appended accompanying drawing is only for reference and explanation usefulness, is not to be used for the utility model is limited.

Above-mentioned is the introduction of structural relation between each element of electric connector, and the mode of the manufacturing of each element of electric connector and assembling is described below: those conducting terminals 20, lower house 31 and upper shell 32 are produced by the punching press processing procedure respectively earlier, those conducting terminals 20 and lower house 31 are put into to an ejection shaping mould (figure does not show) then, just take the manufacture method of mould internal shaping.Material (for example plastics) with glue core body 10 injects in the ejection shaping mould afterwards, and this material can form this glue core body 10.Again glue core body 10, conducting terminal 20 and lower house 31 mould from injection molding is taken out at last, again upper shell 32 is buckled into to lower house 31, both formed the electric connector of present embodiment.

Because respectively have between the contact chip 21 of those conducting terminals 20 and those the protruding walls 14 one at interval, two the colluding and respectively have another interval between sheet 314 and this two projection 18 of this lower house 31, and glue core body 10 has groove 16 and runs through groove 17, in order to reach such design, thus the mould of this injection molding have one corresponding those at interval, two grooves 16 and two run through the shape of groove 17 and the convex structure of position (scheming not formula).

So, when the material of glue core body 10 injects in the ejection shaping mould, corresponding those convex structures are at interval blocked material and are flowed toward the end face of contact chip 21, and flow toward the end face that colludes sheet 314, so contact chip 21 and collude sheet 314 and can not covered by unexpected material; The convex structure of this two groove 16 is kept out before first vertical piece 312 relatively, reduces the strength of these 2 first vertical pieces 312 of material impact, and the vertical piece 312 of winning can be out of shape; This two convex structure that runs through groove 17 is then pushed down this lower casing main body 311 relatively, makes lower casing main body 311 can not be out of shape because of the material impact of glue core body 10.

Comprehensively above-mentioned, the electric connector of embodiment of the present utility model has following effect:

1, have one between the protruding wall 14 of the contact chip 21 of those conducting terminals 20 and glue core body 10 at interval, so during the mould internal shaping, the material of glue core body 10 can not cover to the end face of contact chip 21.

2, two of this lower house 31 collude and have another between the projection 18 of sheet 314 and glue core body 10 at interval, so during the mould internal shaping, the material of glue core body 10 can not cover to the end face that colludes sheet 314.

3, this glue core body 10 has two grooves 16, so during the mould internal shaping, and the material of glue core body 10 clashes into to the strength of first vertical piece 312 of lower house 31 and is lowered, and first vertical piece 312 can be out of shape.

4, this glue core body 10 has two and runs through groove 17, so during the mould internal shaping, lower casing main body 311 can be out of shape because of the material impact of glue core body 10.

But the above only is preferred embodiment of the present utility model; non-ly be intended to limit to protection range of the present utility model; so the equivalence that all utilization the utility model specifications and accompanying drawing content are done changes, and all in like manner all is contained in the protection range of the present utility model explanation hereby.
