Description

Electric connector

[technical field]

The invention relates to a kind of electric connector, especially refer to a kind of electric connector with ground connection effect.

[background technology]

During electronic device works, the capital has intermittently or the continuity electric current and voltage changes, produce electromagnetic interference (Electromagnetic Disturbance, EMI), electromagnetic interference is produced by radiation and traditional approach usually, therefore all suitably ground connection (Grounding), shielding (Shielding) or filtering (Filtering) designs of any electronic equipment reduce electromagnetic interference as far as possible, with the requirement of the electromagnetic compatibility (EMC) that meets electronic equipment.

Low-voltage differential signal (Low Voltage Differential Signal, be called for short LVDS) be a kind of circuit signal of high-speed transfer mass data, be applicable to that usually resolution is higher than on the interface of TFT LCD display unit, optical-fibre communications and electronic switching system of SVGA.The low-voltage differential signal connector of traditional low-voltage differential signal interface standard; the metal shell that comprises insulating body, is contained in the some earth terminals in the described insulating body and coats described insulating body; described metal shell is provided with a ground strip; earth terminal is welded to ground strip; again ground strip is welded on the metal shell; such connected mode influences the ground connection effect through the phenomenon that rosin joint appears in regular meeting.In addition, Chinese patent has disclosed a kind of like this electric connector No. 201766241, it comprises an insulating body, some conducting terminals, some earth terminals and a grounding plate, earth terminal and grounding plate are one-body molded, though such connector ground connection effect stability, but manufacturing process complexity, production cost are too high.

Therefore, be necessary to provide a kind of new electric connector, to address the above problem.

[summary of the invention]

The object of the present invention is to provide a kind of raising ground connection stability, the simple electric connector of manufacturing process.

To achieve these goals, electric connector of the present invention can adopt following technical scheme: a kind of electric connector, comprise insulating body with accepting groove, be contained in some earth terminals, the signal terminal of described accepting groove and the metal shell that coats described insulating body, described earth terminal, signal terminal comprise connecting portion and docking section respectively, described metal shell comprises upper shell and lower house, described lower house comprises some grounding parts, the described earth terminal of described grounding parts butt.

Compared with prior art, the present invention has following beneficial effect: terminal directly with the lower house conducting of ground connection, in raising ground connection effect, it is simpler that the electric connector production technology also becomes, thereby can effectively enhance productivity, and can effectively reduce the production cost of electric connector.

[embodiment]

Please refer to Fig. 1 to Fig. 5, electric connector 100 of the present invention comprises insulating body 10, is contained in the metal shell 30 of some earth terminals 20, signal terminal 22 and coated insulation body 10 on the insulating body 10.

Insulating body 10 comprises main part 12 and is positioned at a pair of alar part 16 of main part 12 both sides, main part 12 comprises the fixed part 121 that is 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, from its upper surface to lower recess and run through some accepting grooves 124 of flange 123, from accepting groove 124 upper surfaces to lower recess and the jube 18 that runs through some through holes 14 of insulating body and be positioned at accepting groove 124 both sides, the apparent height of jube 18 is higher than accepting groove 124, reserve location earth terminal 20 in the mold cavity of profiled insulation body 10, the projection of signal terminal 22 (not shown), after insulating body 10 moulding are finished, form through hole 14 on the correspondence position of projection, alar part 16 is from the formation that extends back of the side of flange 123.

Jube 18 ends that are positioned at fixed part 121 are provided with the boss 181 that upwards protrudes out and be used for clamping cable (not shown) from its surface, be positioned at the slit 182 that the jube 18 of contact site 122 is recessed to form from its upper surface downwards, jube 18 avoids insulating body 10 to cover earth terminal 20, signal terminal 22, guarantees that electric connector 100 contacts with effectively stablizing of butt connector (not shown).

Earth terminal 20 comprises the connecting portion 201 and docking section 202 that is contained in accepting groove 124, signal terminal 22 comprises the connecting portion 221 and docking section 222 that is contained in accepting groove 124, wherein docking section 202,222 and butt connector (not shown) electrically connect, docking section 202,222 upper surface expose to accepting groove 124, and connecting portion 201,221 is connected with cable (not shown).

Metal shell 30 comprises upper shell 31 and lower house 32, and upper shell 31 has some openings 316, has the shell fragment of bending to insulating body 10 directions 318 in each opening 31.Lower house 32 comprises some flutings 328, described fluting 328 intermeshes and is arranged in two rows, lower house 32 also comprises some grounding parts 33 that extend forward from its front end, and some grounding parts 33 are arranged in row and form laciniation, and grounding parts 33 has the salient point 3301 that upwards protrudes out from its upper surface.These grounding parts 33 butt earth terminals 20 do not need by ground strip, have saved the structure of ground strip, and electric connector 100 structures are simplified, thereby reach the purpose that material, manufacturing and assembly cost reduce.Simultaneously, docking section 202 and the salient point 3301 of earth terminal 20 directly connect, and lower house 32, earth terminal 20 and insulating body 10 are one-body molded, make

lower house

32 and 20 stable connections of earth terminal, do not need welding, can avoid because the imperfect earth that failure welding causes.
