Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, refers to a kind of firm electronic card coupler of assembling especially.

[background technology]

The PC card is a kind of in order to the electronic cards to computer and other communication and electronic equipment interpolation such as expanding units such as internal memory, network and wireless telecommunications, and nearly all mobile computer side is equipped with pc card slot to be used for peripheral functions such as Extended RAM or network.PCMCIA (Personal Computer MemoryCard International Association-PCMCIA (personal computer memory card international association)) has announced a kind of new standard of PC card, i.e. Express Card again in 2003 ends.The PC card of this Express Card standard has two kinds of external forms, and a kind of is the L type, and another kind is a rectangle, and the width of rectangle PC card is identical with the minimum widith of L type PC card.And the electric connector that is used for Express Card standard also has two kinds in L type and rectangle.The electric connector of L type can with two kinds of cards in any one connects, and rectangular electric connector can only connect with the PC card of rectangle.

This electric connector is installed on the circuit board usually, mainly comprises insulating body, conducting terminal and metal shell.The welding manner that passes through that metal shell and insulating body have is connected to circuit board, also has the cooperation by screw bolt and nut to be fixed on the circuit board.For the fit system that adopts screw bolt and nut, bolt is to pass circuit board and insulating body or metal shell from the circuit board below usually, and screws in the nut that is positioned at electric connector top, realizes electric connector is fixed on the circuit board with this.The employing column structure that nut also has, it passes metal shell and directly interferes with metal shell and combines, and realizes fixing in the screw of bolt screw-in nut.No matter yet nut adopts above-mentioned which kind of form, in the bolt rotation process, nut might rotate together along with bolt, so often need nut is made additional fixing, could realize installing smoothly.In addition, directly interfere the mode that combines with metal shell for adopting cylindrical nuts to pass metal shell, it is in conjunction with poor effect, and the stressed excessive nut that may cause comes off from housing.The electric connector that the TaiWan, China patent is disclosed for No. 257552 (referring to this patent specification first figure, the 3rd figure and the 9th figure) has adopted a kind of nut 18 of special shape, and the positioner 15 of accommodating this nut, and pass circuit board 200 and insulator 2 from the below, screw in the nut 18 by a bolt 19.Though this mounting means is by the constraint of 15 pairs of nuts 18 of positioner, prevented that to a certain extent nut from coming off, and nut is followed the situation generation that bolt rotates together in bolt 19 rotary courses, but it adopts member more, element structure is comparatively complicated, installs also comparatively complicated.

For fear of the problems referred to above, the utility model proposes a kind of new electronic card coupler to compensate its defect.

[utility model content]

The purpose of this utility model is to provide a kind of easy to assembly, firm electronic card coupler.

The purpose of this utility model is achieved through the following technical solutions: a kind of electronic card coupler, and it comprises: insulating body; Be contained in the plurality of conductive terminals in the insulating body; Be shielded in the shielding casing on the insulating body; Wherein, this electronic card coupler also comprises nut, and it is installed on the shielding casing, and this nut is provided with several cylinders and is contained on the shielding casing.

Compared with prior art, electronic card coupler of the present utility model is connected on the shielding casing by cylinder is set on the nut, can prevent lock during screw the nut phenomenon of spinning take place, simultaneously, can increase the bond strength between nut and the metal shell effectively, make this electric connector assembling firmly, conveniently.
