[embodiment]
Below preferred embodiment is described in detail to the utility model, see also Fig. 1 and Fig. 2, the utility model device for fastening 1 and a pair ofly be positioned at that electric connector 4 mutual group of both sides are loaded on the circuit board 5 before and after it, the both sides, front and back of device for fastening 1 are promptly and form the space that power supply subcard 6 holds between the electric connector 4 respectively.Two electronic cards 6 back-to-back placements, its front end is inserted into respectively in the electric connector 4, and tail end is fixed by device for fastening 1.
Emphasis is with reference to Fig. 3, and device for fastening 1 comprises the pedestal 2 that insulating material is made and is fixed in a pair of retainer 3 of both sides, pedestal 2 front and back.The both sides, front and back of pedestal 2 form the space that the power supply subcard holds respectively.Pedestal 2 comprise lengthwise base portion 20 and in base portion 20 two ends the sidepiece 21 that extends to form of both sides forwards, backwards respectively, and make pedestal 2 be " worker " font.The both sides, front and back of base portion 20 are extended upward by the bottom respectively and form a pair of clamping part 200, form clip slot 201 between itself and the base portion 20.On base portion 20, offer a pair of pre-and post perforative through hole 202 between two clamping parts 200 of homonymy.The both sides, front and back of sidepiece 21 respectively are provided with by upwardly extending reference column 210 in surface and block 211.Respectively insert a bonding pad 22 in the rear and front end of sidepiece 21, be used for pedestal 2 is fixed to circuit board.
When two retainers 3 were mounted to pedestal 2, roughly between two clamping parts 200 of pedestal 2 homonymies, elastic arm was arranged in clip slot 201 to the connecting portion 30 of retainer 3.Block 211 on the pedestal sidepiece 21 is positioned at the front side of pulling part 33 of retainer 3 to limit its over-deflection.Perforation 300 on two retainers 33 and the 202 corresponding perforations of the through hole on the pedestal, and pass the back riveted successively by a pair of rivet 7, thus the three is linked to each other.Rivet 7 shown in Fig. 3 is the structure behind riveted.After two retainers 3 assembling was finished, it was individually fixed in the opposite both sides, front and back of pedestal 2, and is back-to-back setting.Have two on each retainer 3 and be positioned at its terminal holding part 32, the holding part 32 of different retainers is positioned at the opposite both sides, front and back of pedestal, and bending extension in the opposite direction respectively.On the fore-and-aft direction of pedestal, the line that is positioned at two holding parts 32 of pedestal front side parallels with the line of two holding parts 32 that are positioned at rear side.On the perpendicular left and right directions of pedestal and aforementioned fore-and-aft direction, the line that is positioned at the holding part 32 in pedestal left side parallels with the line of the holding part 32 that is positioned at the right side.According to the setting of above holding part, 6 of a pair of electronic cards can be symmetrically and the back-to-back opposite both sides, front and back of device for fastening 1 that are held in.The holding part 32 of retainer 3 is stuck in the surface of electronic cards rear end, and the reference column 210 of pedestal 2 is arranged in the respective aperture (not label) of electronic cards 6 rear ends.When need discharge electronic cards 6, pull the pulling part 33 of retainer 3 backward, holding part 32 is removed from the electronic cards surface, thereby makes electronic cards to take off.
More than be the description of the utility model most preferred embodiment, can also derive other a lot of execution modes, be made of one formula, hold function as long as have corresponding button as pedestal and retainer according to this thought.And for example, in most preferred embodiment, each retainer is along the parallel placement of electronic cards end edge, and two holding parts on it are held in same electronic cards, and if the direction that retainer edge and electronic cards end edge is perpendicular is placed, the holding part at its two ends is detained respectively and held different electronic cards also is feasible.Certainly, holding part and nonessential being formed in twos on the same retainer, each independently is provided with still can realize creative ideas of the present utility model.
