Abstract

The utility model concerns an electronic card connector, comprises an insulation body, a conductive terminal, a grounding component, a card withdrawing component and a covering shell body. The covering shell body, the card withdrawing component and the insulation body on which the conductive terminal is arranged are assembled and electrically connected with the grounding component. The covering shell body is provided with a main body part and two lateral wall parts which respectively extend vertically out from both lateral edges of the main body part. Each lateral wall part is provided with an opening and a beam type elastic plate which is connected with the two opposite lateral edges of the opening and extends therein. The central part of the elastic plate bends inward to insert into the electronic card shell in the electronic card connector and electrically connects with the shell, thus the static charges which accumulate on the outer surface of the electronic card can be released.

Description

Electronic card coupler

The utility model is relevant a kind of electronic card coupler, relates in particular to a kind of shielding casing of electronic card coupler.

Electronic card coupler electrically connects circuit board, and the power supply subcard is planted wherein to realize the telecommunication transmission between electronic cards and circuit board.But electronic card coupler is typically provided with the shielding casing of the earthing device of butt electronic cards outer surface, particularly, the shielding casing of electronic card coupler is to borrow the ground path on earthing device and the circuit board to electrically conduct, thereby the electrostatic charge that will insert on the interior electronic cards outer surface of electronic card coupler is eliminated.

See also shown in Figure 1ly, existing electronic card coupler 1 comprises insulating body 2, some conducting terminal 3, earthing components 4 that is installed up to insulating body, moves back clamping member 5 and shielding casing 6.This shielding casing 6 comprises the side wall portion 60 that main part 66 and a pair of autonomous body 66 two opposite sides marginal lappets directly extend.Each side wall portion 60 front end is provided with an opening 62.In one beam type shell fragment 64 extends back into opening 62 from each opening 62 leading edge, so that after electronic cards inserts this electronic card coupler 1, the free terminal 68 of shell fragment 64 slightly bends inwards and can contact with this electronic cards, thereby the electrostatic charge on the electronic cards outer surface is imported ground path.Yet, being formed with free terminal 68 that breach makes shell fragment 64 between the trailing edge owing to the end 68 of shell fragment 64 and this opening 62 is very easily stretched into foreign object in this breach accidentally and colludes and be out of shape, so its function that contacts with electronic cards of forfeiture, thereby can't lead away the electrostatic charge that is gathered on the electronic cards, influence the stability of signal transmission.Therefore, be necessary this electronic card coupler is improved in fact, to overcome the shortcoming of aforementioned prior art.

The purpose of this utility model is to provide a kind of can be guaranteed that grounding path is continuous, unimpeded and can effectively discharge the electrostatic charge that is gathered on the electronic cards, to guarantee the electronic card coupler of signal transmission quality.

The purpose of this utility model is achieved through the following technical solutions: this electronic card coupler comprises insulating body, is mounted to the conducting terminal of insulating body, earthing component, move back clamping member and shielding casing.This shielding casing with move back clamping member and insulating body and assemble mutually and electrically contact with earthing component.Shielding casing is provided with main part and the anterior vertical extent of autonomous respectively body two opposite sides edge and the side wall portion that goes out.The cross beam type shell fragment that each side wall portion front portion is provided with opening and joins and therebetween extend with opening two opposite sides edge.Shell fragment and this shielding casing one punch forming and two ends are fixed, and in the position, intermediate portion curve inwardly with insert electronic card coupler in electronic cards contact, discharge thereby reach static.

Compared with prior art, advantage of the present utility model is: shell fragment and the punching out of shielding casing one form, two ends all are connected to a fixed with the side wall portion of shielding casing, the free terminal that does not have prior art is because of jagged defective of easily being colluded by foreign object, thereby the static release performance of electronic card coupler has reliable assurance, improves the quality of signal transmission.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the three-dimensional exploded view of existing electronic card coupler.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a three-dimensional combination figure of the present utility model.

Fig. 4 is a partial enlarged drawing of the present utility model.

Please consult shown in Figure 2ly earlier, the utility model electronic card coupler 100 includes insulating body 200, plurality of conductive terminals 300, earthing component 400, moves back clamping member 500 and shielding casing 600.

Insulating body 200 is provided with a base portion 201 and a pair of arm 203 that extends setting at base portion 201 both ends along fore-and-aft direction, and arm 203 is parallel to each other.Conducting terminal 300 is retained on the base portion 201 of insulating body 200, the docking section 301 and the installation portion 303 of terminal 300 protrudes in the front and back end of base portion 201 respectively, wherein docking section 301 can be docked with electronic cards (not shown), and installation portion 303 then can be in order to be electrically connected to terminal 300 on the circuit board (not shown).

Earthing component 400 comprises a contact site 401 and some contact feets 402 that extends vertically downward along contact site 401 back edge.

Move back clamping member 500 and be prior art, so its structure is not described herein.

Shielding casing 600 comprises the side wall portion 603 that a main part 601 and directly extends for main part 601 anterior two opposite sides marginal lappets.Each side wall portion 603 front end is provided with an opening 605.Please consult Fig. 4 simultaneously, both side edges were joined and are therebetween extended before and after a cross beam type shell fragment 606 and this opening 605 were relative, and its middle part concaves and into protrudes into portion 607 to form one.One side wall portion, 603 middle parts are provided with the U type support portion 608 that stretches out.

Please consult Fig. 3 simultaneously, during assembling, thereby earthing component 400, move back clamping member 500 and shielding casing 600 is installed to the assembling of finishing this electronic card coupler 100 on the insulating body 200 that is equiped with conducting terminal 300 in the prior art mode.The contact site 401 of earthing component 400 is placed between the upper surface of base portion 201 of the rear portion lower surface of main part 601 of shielding casing 600 and insulating body 200, and electrically contact with this main part 601, its contact feet 402 then with the mode identical with the installation portion 303 of conducting terminal 300 be mounted to circuit board (not shown) with circuit board on ground path electrically connect, think that the conducting terminal 300 that electrically connects with electronic cards (not shown) provides electrical shielding.This moves back clamping member 500 is installed on the arm 203 of insulating body 200, and by support portion 608 local support of this shielding casing 600, and can move up in front and back to realize moving back the function of card.The lateral displacement that moves back clamping member 500 is stoped by this support portion 608.

When electronic cards was inserted this electronic card coupler 1, shell fragment 606 can borrow its inside recessed portion that protrudes into 607 to contact with the shell of electronic cards, leads away by the earthing component 400 that is connected with circuit board with the electrostatic charge that will accumulate on the electronic cards shell.
