Abstract
An electronic card connector comprises an insulation body, conductive terminals which are fixedly arranged in the insulation body, a switch terminal, a card-retreating mechanism, a shielding housing which is covered on the insulation body and a metal bottom shell which is internally moulded on the bottom surface of the insulation body, wherein the shielding housing and the insulation body define an accommodation space. The insulation body comprises a base portion, side portions which extend from the two sides of the base portion to the electronic card retreating direction, and a crossbeam which is connected with the two side portions and is close to the electronic card inserting direction. The metal bottom shell and the insulation body are integrated into to one body. A metal foot is integrated at the connection point of the side portions of the insulation body and the crossbeam on the metal bottom shell. The metal foot is capable of preventing the case of plastic flow confusion from happening due to large width difference of the junction point of the side portions and the crossbeam, so that the flatness of the molded insulation body is improved.
Description
[technical field]
The present invention relates to a kind of electronic card coupler.
[background technology]
Along with the fast development of the consumption electronic products such as mobile phone, digital camera, under the prerequisite of especially rapidly expanding in the function of various electronic products, the memory capacity of these equipment itself can not satisfy the demands of consumers.Therefore, electronics manufacturer adds electronic card coupler to connect outside storage card medium in electronic equipment, to expand the memory capacity of electronic equipment.So, be exclusively used in the electronic card coupler that group connects various electronic cards and be widely used in various electronic equipments.
Electronic card coupler of the prior art, please refer to Chinese patent and announce shown in No. CN201741850U, this electronic card coupler includes insulating body, some conducting terminals, switch terminal, is covered in the shielding casing on insulating body and is assembled in insulating body one side for pushing away the trip mechanism that moves back electronic cards; Wherein shielding casing and insulating body define and form in order to accommodate the receiving space of electronic cards.Described insulating body comprises two sidepieces that are positioned at the base portion of plug-in card end, extend to electronic cards exit axis respectively from base portion both sides and connects both sides and near the crossbeam of electronic cards insert port direction, this crossbeam and base portion are greatly to be arrangeding in parallel and being separated by specific range.Described trip mechanism is fixedly arranged on an above-mentioned wherein sidepiece place.
But due to the development trend of miniaturization of electronic products, in prior art, the general design of the sidepiece of insulating body is very narrow, thus simultaneously for the crossbeam of fixed terminal generally than the wide a lot of fixing dynamics that guarantee terminals of described sidepiece.During profiled insulation body, the plastic cement at sidepiece place flows slower, because crossbeam is wide more a lot of than sidepiece, when plastic cement flows to crossbeam place, width broadens suddenly, its sudden change can cause that plastic cement flows chaotic and then causes the not good warpage that even can produce in various degree of insulating body flatness after moulding bad, particularly near sidepiece and crossbeam intersection.
In view of above problem, be necessary to provide a kind of improved electronic card coupler in fact, to address the above problem.
[summary of the invention]
The object of the present invention is to provide a kind of electronic card coupler, espespecially a kind of electronic card coupler that prevents insulating body buckling deformation.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of electronic card coupler, comprises insulating body, is fixedly arranged on some conducting terminals, switch terminal in insulating body, is assembled in insulating body one side and for pushing away, moves back the trip mechanism of electronic cards, be covered in the shielding casing on insulating body and take shape in the metal drain pan in insulating body bottom surface; Wherein shielding casing and insulating body define and form in order to accommodate the receiving space of electronic cards; Described insulating body comprises the crossbeam that is positioned at the base portion of plug-in card end, the sidepiece extending from base portion two side direction electronic cards exit axis and connection both sides and close electronic cards insert port direction; Described metal drain pan and insulating body are one-body molded; On described metal drain pan, to receiving space one side, extended to form metal leg, described metal leg is shaped in crossbeam one end of insulating body near side locations place.
Further, described metal drain pan comprises the base plate being immobilizated in insulating body and the side plate being bent to form along base plate both side edges, described metal leg along side plate to receiving space one side, extend to form and with mutually vertical setting of side plate.
Further, the metal leg on described metal drain pan includes long metal leg and short metal leg.
Further, described short metal leg in the vertical direction is positioned at the top of long metal leg, and described short metal leg is than the more close plug-in card end of long metal leg.
Further, between described long metal leg and short metal leg, be arranged in parallel.
Further, the base portion end edge of described insulating body extends upward and is formed with rear wall, and described switch terminal includes and is fixedly arranged on the long end son at rear wall one side place, the base portion that is fixedly arranged on short end at rear wall opposite side place and is fixedly arranged on insulating body near rear wall place and the fixed terminal that matches with long end.
Further, described electronic card coupler is not when electronic cards is inserted receiving space, and the long end of described switch terminal is with fixed terminal in closure state, and the long end of described switch terminal and short end are in off-state simultaneously.
Further, when described electronic card coupler inserts receiving space completely in electronic cards, the long end of described switch terminal is with fixed terminal in off-state, and the long end of described switch terminal and short end are in closure state simultaneously.
Further, described Hou Qiang both sides offer respectively holddown groove and the holding slot for fixed length terminal and short end near side locations.
Further, the left and right side wall that described shielding casing includes crown wall and is bent to form downwards along crown wall both sides, on the side wall of described left and right, offer holding hole, be formed with the retaining sheet that hold corresponding to holding hole on the side plate of described metal drain pan, described retaining sheet is bent to form to receiving space opposition side.
Compared with prior art, electronic card coupler of the present invention at least has the following advantages: metal drain pan has extended to form metal leg to receiving space one side, and described metal leg is shaped in close sidepiece and the crossbeam intersection in crossbeam one side.During profiled insulation body, by described metal leg, prevent that sidepiece and crossbeam intersection from occurring because width difference produces greatly the mobile chaotic situation of plastic cement, thereby improve the flatness, particularly sidepiece of the insulating body after moulding and the flatness of crossbeam intersection.
