[technical field]
The invention relates to a kind of electric connector, especially a kind of terminal and the integrated electric connector of insulating body.
[background technology]
In electronic equipment miscellaneous, can signal transmission can be described as the soul place reaching feature operation, especially becomes more important when each functional circuit system decentralized design of electronic equipment when.Such as, in order to the image data that computer can be produced, transfer to Liquid Crystal Module (Liquid Crystal Module fast and correctly, be called for short LCM) upper display, a kind of low-voltage differential signal (Low Voltage Differential Signal, be called for short LVDS) interface standard, owing to having the property requirements of high anti-jamming capacity and high-speed transfer, become the important interface that liquid crystal display (Liquid Crystal Display is called for short LCD) transmits data.
Though have many low-voltage differential signal connectors meeting low-voltage differential signal interface standard on the market at present, during insulating body injection mo(u)lding, terminal can not be located effectively and accurately, and the performance of product and quality are had a greatly reduced quality.Therefore, be necessary to provide a kind of new electric connector, to solve the problem.
[summary of the invention]
The object of the present invention is to provide a kind of electric connector that terminal accurate and effective is located.
To achieve these goals, electric connector of the present invention can adopt following technical scheme: a kind of electric connector, comprise insulating body, be contained in the metal shell of some terminals in described insulating body and coated described insulating body, described insulating body has main part, described main part comprises the fixed part being positioned at its rear end, the contact site being positioned at its front end and the accepting groove be recessed to form downwards from its upper surface, described terminal is contained in described accepting groove respectively, the upper surface of described terminal exposes to described accepting groove, described insulating body also comprises the jube of accepting groove described in interval, described jube is provided with the groove be recessed to form from described contact site upper surface downwards.
Compared with prior art, the present invention has following beneficial effect: insulating body is provided with a groove, when insulating body injection mo(u)lding, the projection of reserved positioning terminal in the mold cavity of profiled insulation body, projection is held on terminal both sides, guarantees that terminal left and right displacement does not occur, and makes the position between insulating body and terminal keep stability, consistency, insulating body is shaping complete after, the correspondence position of projection forms groove.

[embodiment]
Please refer to Fig. 1 to Fig. 4, electric connector 100 of the present invention comprise insulating body 10, be contained in the metal shell 30 of some terminals 20 on insulating body 10 and coated insulation body 10.
Insulating body 10 comprises main part 12 and is positioned at a pair alar part 16 of main part 12 both sides, main part 12 comprises the fixed part 121 being positioned at its rear end, be positioned at the contact site 122 of its front end, flange 123 between fixed part 121 and contact site 122, run through some accepting grooves 124 of flange 123 from its upper surface to lower recess and be positioned at the jube 18 of accepting groove 124 both sides, the apparent height of jube 18 is higher than accepting groove 124, some alar parts 16 to extend back formation from the side of flange 123, accepting groove 124 is provided with the staggered some shrinkage pools 1240 running through accepting groove 124 upper and lower surface, when insulating body injection mo(u)lding, the boss (not shown) of reserved positioning terminal 20 in the mold cavity of profiled insulation body 10, insulating body 10 is shaping complete after, the correspondence position of boss is formed shrinkage pool 1240.
Jube 18 end being positioned at fixed part 121 is provided with and upwards protrudes out from its surface and boss 184 for clamping cable (not shown), a pair first step portion 181 that the jube 18 being positioned at contact site 122 is recessed to form downwards from its upper surface, the a pair second step portion 182 be recessed to form downwards from first step portion 181 and groove 183, the height in first step portion 181 is lower than second step portion 182, groove 183 is between second step portion 182 and be recessed to form downwards by the upper surface of contact site 122, when insulating body injection mo(u)lding, the projection (not shown) of reserved positioning terminal 20 in the mold cavity of profiled insulation body 10, insulating body 10 is shaping complete after, the correspondence position of projection is formed groove 183, for making positioning terminal 20 effect better, groove 183 also can run through contact site 122 upper and lower surface.
Terminal 20 comprises the docking section 201 and connecting portion 202 that are contained in accepting groove 124.Wherein docking section 201 and butt connector (not shown) are electrically connected, and the upper surface of docking section 201 exposes to accepting groove 124, and connecting portion 202 is connected with cable (not shown).
Metal shell 30 comprises upper shell 31 and lower house 32, and upper and lower casing 31,32 is mounted to insulating body 10 respectively above and below insulating body 10.Metal shell 30 makes well to coordinate between metal shell 30, between metal shell 30 with insulating body 10 by working in coordination between the groove 1102 on the shell fragment 312 coordinated insulation body 10 on it and upper-lower casing 31,32, and wherein metal shell 30 is exposed in the front end of the contact site 122 of insulating body 10.Upper shell 31 has some openings 316, has the shell fragment 318 curved to insulating body 10 direction in each opening.Lower house 32 comprises some flutings 328, and described fluting 328 intermeshes and is arranged in two rows.
The rear portion of metal shell 30 forms the fixing arm 34 that a pair is given prominence to outside, insulating body 10 both sides respectively.Fixing arm 34 comprises a pair shell body 314 of upper shell 31 both sides and a pair inner housing 324 of lower house 32 both sides.Each inner housing 324 has a pair elasticity bent sheet 326.Bent sheet 326 bends inwards and upper shell 31 and lower house 32 is more easily installed.
Some boss (not shown) of positioning terminal 20 and some projections (not shown) is provided with in mould due to profiled insulation body 10, this boss is conflicted at the lower surface of terminal 20, terminal is not moved forward and backward, projection is clamped in the both sides of terminal 20, terminal 20 is made left and right displacement not to occur, boss and projection cooperatively interact, and ensure that terminal 20 is positioned the design attitude of electric connector 100, make position between insulating body 10 and terminal 20 keep stability, consistency.
Because lower house 32 can put into mould, one-body molded with insulating body 10, this projection also can locate lower house 32, and lower house 32 is combined better with insulating body 10.
