[embodiment]

The ginseng Figure 1 and Figure 2, the utility model electric connector 100 is in order to accommodate a kind of electronic cards and to be welded on a kind of motherboard of electronic equipment, thereby realize the signal transmission between electronic cards and the motherboard, this electronic equipment can be slimming notebook computer or panel computer or other similar slimming electronic products.Electric connector 100 comprises insulating body 1 and is contained in one in the insulating body 1 arranges conducting terminal 2.

Ginseng Fig. 3 is to shown in Figure 5, insulating body 1 is the rectangular shape of lengthwise, and comprise the first side wall 11 that is oppositely arranged with the second sidewall 12, be connected the rear wall 13 of the first side wall 11 and the second sidewall 12 and be positioned at the first side wall 11 and the end walls 14 at the second sidewall 12 lengthwise two ends.Also be provided with long and narrow central slot 10 between the first side wall 11 and the second sidewall 12 to accommodate electronic cards, central slot 10 is provided with knob of key 15 in a close wherein side of an end wall 14 and inserts in the central slot 10 with the direction of mistake to prevent electronic cards.The bottom surface of the first side wall 11 forms installed surface 111, the second sidewalls 12 and arranges away from this installed surface 111, and the first side wall 11 and the second sidewall 12 lay respectively at the relative both sides of central slot 10.

The second sidewall 12 is towards the laterally inclined approaching face 121 that extends to form of central slot 10, and described approaching face 121 inserts in this central authorities' slot 10 along this approaching face 121 in order to guide electronic cards to tilt with certain angle.The second sidewall 12 is being interval with some terminal containing slots 122 along longitudinally, this terminal containing slot 122 runs through approaching face 121 downwards being connected with central slot 10, and runs through backward rear wall 13 to form holddown groove 131 on rear wall 13.On the first side wall 11 in the utility model electric connector 100 terminal containing slot is not set, be that conducting terminal is not set on the first side wall 11, therefore, the thickness of this first side wall 11 can reduce greatly, can make the thickness of the first side wall 11 less than the thickness of the second sidewall 12, thereby reduce the height of whole electric connector 100, make this electric connector 100 adapt to the trend of miniaturization development.

Conducting terminal 2 is for metal material is bent to form, and is set to a row and is contained in the terminal containing slot 122 on the second sidewall 12.Each conducting terminal 2 comprises holding parts 21, bends forward the contact arm 22 that extends and the weld part 23 that extends back from holding parts 21 from holding parts 21, holding parts 21 is the tabular setting and both sides are provided with protruding thorn, and contact arm 22 has elasticity and front end is provided with the contact site 221 that is bent to form.Conducting terminal 2 is in the rear wall 13 of the body 1 that insulate is assembled in forward terminal containing slot 122 on the second sidewall 12, wherein holding parts 21 is fixed in and can makes conducting terminal 2 stable being fixed in the insulating body 1 in the holddown groove 131, contact arm 22 only is a row and arranges and be contained in the second sidewall 12, the approaching face 121 that the contact site 221 that arranges on the contact arm 22 runs through described the second sidewall 12 is to protrude in the central slot 10, and 23 of weld parts extend back insulating body 1.On fore-and-aft direction, the first side wall 11 protrudes out forward the second sidewall 12, be that the first side wall 11 is different with the length of the second sidewall 12 on fore-and-aft direction, thereby form an insert port that is tilted to (not label) to make things convenient for electronic cards to tilt to insert at the front end of central slot 10.

Generally, this type of existing electric connector has the two row's conducting terminals that are oppositely arranged, and need to arrange two row's terminal containing slots on the two lateral walls of insulating body to accommodate respectively two corresponding row's conducting terminals, yet the insulating body that two row's terminal containing slots are set also needs to possess enough intensity simultaneously, therefore insulating body arranges two two lateral walls of arranging terminal containing slots larger thickness need to be set, the height that this will increase this type electric connector undoubtedly, the development trend that is unfavorable for hanging down structure.In the utility model electric connector, conducting terminal 2 design is in a row and be arranged on second sidewall 12 away from installed surface 111 of insulating body 1, only need at the second sidewall 12 of insulating body 1 row's terminal containing slot 122 to be set, and need not fixing conducting terminal on the first side wall 11 relative with the second sidewall 12, thereby the thickness of the first side wall 11 can be reduced, reduce the height of whole electric connector 100, make this electric connector 100 adapt to the trend of miniaturization development.Contact arm 22 only is a row and arranges and be contained in the second sidewall 12, can make contact site 221 away from the first side wall 11, so that enough resilient clamp power to be provided.

In sum, it below only is preferred embodiment of the present utility model, should not limit scope of the present utility model with this, i.e. every simple equivalence of doing according to the utility model claims and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
