[embodiment]

Consult Fig. 1 to Fig. 7, be depicted as and embody a kind of electric connector 100 of the present invention.Consult Fig. 1 and Fig. 2, this electric connector 100 is in order to be installed on a kind of circuit board 120 of electronic equipment, and it has the RJ45 socket 20 of stacking setting and the general serial socket 50 of double nip.

As shown in Fig. 3 and Fig. 5, this electric connector 100 comprises insulating body 200, is installed in terminal module 400, display unit 700 and shield shell 600 in insulating body 200.Described insulating body 200 is provided with and can inserts the receiving space 20 coordinating for butt connector RJ45 connector.Described terminal module 400 comprises the docking terminal 42 that inserts in income-space 20 to coordinate with RJ45 connector conduction, carry and be electrically connected dock terminal 42 internal circuit board 40, be arranged at the switching module 44 that internal circuit board 40 can be filtered some electronic components 46 of noise and is arranged at internal circuit board 40.Switching module 44 can will be passed to docking terminal 42 by RJ45 connector, and is forwarded to described circuit board 120 by internal circuit board 40 and the signal of described electronic component 46.Described shield shell 600 comprises that from front and back two directions are covered respectively and establishes and the procapsid 620 and back casing 640 of insulating body 200 and terminal module 400.

Consult described in Fig. 3 to Fig. 7 internal circuit board 40 and be provided with and have conductive through hole 401, conductive through hole 401 has relative two side (not label).Described back casing 600 is provided with the insertion section 647 of inserting aforementioned conductive through hole 401, thereby described insertion section 647 compresses and coordinates formation conduction to be connected ground connection with the two opposite side walls of conductive through hole 401.Because insertion section 647 compresses effect with the two opposite side walls of conductive through hole 401, thereby very little to other position effect of stress of back casing 640 simultaneously, avoid back casing 640 distortion.Certainly, conductive through hole 401 can be set to have any groove shape of two opposite side walls, as long as it is subject to two active forces of insertion section 647 at contrary both direction.

Described insertion section 647 ends are arranged with two lug extending in parallel 648, two lugs 648 and compress and coordinate with the two lateral walls of conductive through hole 401 respectively.In the present embodiment, the extending end of two lugs 648 in a certain distance apart from one another so that two lugs 648 coordinate and have suitable elastic force with compressing of described two side.Its actual can be according to active force needs, be arranged to fish eyelet form by press-fitting structure; Can be by the small distance distance of being arranged to be separated by between two lugs 648, insertion section 647 is inserted after conductive through holes 401, the extending end of two lugs 648 mutually against, to increase, compress active force; Can also between two lugs 648, be arranged to be separated by larger distance distance and development length is larger, thus the active force of 648 pairs of conductive through hole 401 two sides of lug reduced.

Described internal circuit board 40 is that vertical aforementioned circuit plate 120 arranges, and described conductive through hole 401 is arranged in internal circuit board 40 tip position away from described circuit board 120.Insulating body 200 has front end face 22 and end face 26.Described procapsid 620 comprises the antetheca 622 and the roof 626 that is covered in insulating body 200 end faces 26 that is covered in insulating body 200 front end faces 22.Back casing 640 comprises the back casing 640 that is in the rear wall 644 of electric connector 100 back-end locations and is covered in insulating body 200 two sides 24.Rear wall 644 apical positions of described back casing 640 are provided with the connecting portion 646 that insertion section 647 is extended and connected in bending, and insertion section 647 is to form from kink 646 horizontal-extendings.

In addition, internal circuit board 40 has the two sides 403 of vertical described circuit board 120 and internal circuit board 40, and in two sides 403 conductive regions 405 that are respectively equipped with circular arc, the shell fragment 643 that described back casing 640 extends internally in the conductive region 405 die-cut formation in position, described shell fragment 643 has the arc contact end that elasticity is connected to described conductive region 405, to reach good grounding connection by back casing 640.
