[background technology]

Notebook computer is mostly organized on motherboard and is provided with electronic card coupler, makes it carry out the telecommunication transmission with the outside data access arrangement, and the connector volume reduces and the telecommunication conveying capacity increases the trend that has become the notebook computer development.Yet the increase of transmission speed and conducting terminal density causes telecommunication more seen seriously by the interference of electronic noise in the environment, and the static that electronics is stuck in its surface aggregation when pegging graft also can influence the quality of telecommunication transmission, so the stability of grounding construction to guarantee that telecommunication is transmitted that electrically connects with the motherboard ground path is set on electronic card coupler usually.And, for making electronic card coupler not take too much board area, industry mostly is provided with bracing or strutting arrangement in the electronic card coupler lower end, so that can arrange on the circuit board of electronic card coupler downside and establish other electron component, and this bracing or strutting arrangement has grounding function simultaneously, and relevant prior art can be consulted United States Patent (USP) the 5th, 033, No. 972 and the 6th, 231, cases such as No. 382.

Industry adopts screw or welding method that bracing or strutting arrangement is assembled on the circuit board usually.See also Fig. 5 and shown in Figure 6, should existing electronic card coupler 4 be to be installed on the circuit board 2 by screw 3, bracing or strutting arrangement 44 comprises holding part 440 and base portion 441, and it is roughly L-shaped, and this holding part 440 is provided with first button hole and second button hole (not indicating).On shielding casing 42, be respectively equipped with first trip 422 and second trip 424 corresponding to first button hole and second button hole, so that this bracing or strutting arrangement 44 is immobilizated on the shielding casing 42, this base portion 440 is provided with locating piece 442, have internal thread hole on this locating piece 442, be provided with location hole 20 corresponding to this internal thread hole place on the circuit board 2.For making screw 3 can adapt to needs on the circuit board that is installed to different-thickness, the length of screw 3 is bigger usually, thereby it is also bigger to make that screw tail end 31 exposes the height of circuit board.When screw 3 when bracing or strutting arrangement 44 is locked in circuit board 2 belows, the tail end 31 of screw 3 stretches out locating piece 442 and is exposed to the top of circuit board 2.Screw 3 may touch other electronic installation in the process of circuit board assembling, make between bracing or strutting arrangement 44 and the circuit board 2 be connected loosening, influence the reliability that electrically connects between electronic card coupler and the circuit board, screw 3 also can damage or scratch other electronic installation, not only influence the outward appearance of these electronic installations, also may cause the disabler of these electronic installations, thereby influence the circuit board group process of assembling and cause production cost to increase.

Therefore, the needs design is a kind of has the electronic card coupler of improved bracing or strutting arrangement to overcome above-mentioned shortcoming.

[summary of the invention]

The purpose of this utility model is to provide a kind of electronic card coupler with bracing or strutting arrangement, when electronic card coupler is assembled on the circuit board, can prevent that bracing or strutting arrangement is assembled used screw to be touched mutually with other electronic installation, to guarantee the normal operation of electronic card coupler and other electronic installation.

For achieving the above object, the utility model adopts following technical scheme: electronic card coupler comprises the insulating body that contains plurality of conductive terminals, shielding casing and the bracing or strutting arrangement that is covered in the insulating body top.Bracing or strutting arrangement is located at described shielding casing both sides, this bracing or strutting arrangement includes holding part that is fastened on shielding casing and the base portion that is extended and engaged with circuit board by the end bending of this holding part, the perforate that matches with screw on the base portion, the edge bending of holding part is extended with masking device to cover screw.

Compared to prior art, the utility model holding part is provided with masking device, this masking device forms the shed space to cover screw in the screwed hole top, and the position that screw may skid off covered, can prevent effectively that screw from touching mutually with other electronic installation, thereby assurance electronic card coupler and other electronic installation are put normal operation.
