Abstract
The utility model relates to an electronic card connector. The utility model mainly comprises a connector body, a card withdrawal mechanism arranged on one side of the connector body, an earthing strip covered on the connector body, a fastening device provided with a fastening member and a press plate strip, etc., wherein, at least one fastening hole is arranged on one surface of an insulation body, and through holes are respectively arranged on the earthing strip and the press plate strip, corresponding to the fastening hole; the press plate strip is fixedly connected with the fastening hole on the insulation body through the fastening member, so as to cause the press plate strip to tightly press and fix on the earthing strip; further more, during the processes that the earthing strip is inserted or is withdrawn from an electronic card, an arching and deformation phenomenon or a looseness phenomenon are prevented.
Description
The utility model is a kind of electronic card coupler, relates in particular to a kind of electronic card coupler with ground strip firm joint device.
Because the electromagnetic interference that the external world and electronic installation internal electronic element are produced is at all times, especially in electronic component deploying on the motherboard more and more closely under the situation, electromagnetic interference between the electronic component is especially serious, and this will seriously influence the quality of telecommunication transmission.In order to improve above-mentioned condition, in current many designs, be equipped with earthing mechanism, as shown in Figure 1 and Figure 2, in this electronic card coupler 7, ground strip 71 cover caps are in a side of insulating body 73,72 of set cards snap in the draw-in groove set on the insulating body 73 731 on it, so that ground strip 71 is fixed on the insulating body 73.In addition, stretching out at the one lateral margin is provided with several earth terminals 74, is connected by the grounded circuit of these earth terminals 74 with circuit board (not shown), and then reaches the function that prevents electromagnetic interference.But each member on this electronic card coupler 7 is because the restriction of manufacturing technology and relevant tool, in manufacture process and produce scale error and mismatch error.Thereby, after card 72 and draw-in groove 731 fix, can not guarantee between these two members very close to each other, so that insulating body 73 can't provide firmly locatees ground strip 71, and after this product is repeatedly inserted, moved back card motion, can make the ground strip 71 generations distortion (as shown in Figure 3) of arching upward inadequately because of the confining force of 731 of card 72 and draw-in grooves, like this, to cause the grounded circuit loose contact of this electronic card coupler 7, and make it can not prevent electromagnetic interference effectively.
Main purpose of the present utility model is to provide a kind of ground strip can not produce to arch upward distortion and then guarantees the grounded circuit contact stabilization, to reach the electronic card coupler that prevents that effectively noise from disturbing.
The purpose of this utility model is to realize like this, on insulating body one surface of this electronic card coupler, be provided with coupling hole, and be provided with through hole with respect to this coupling hole place at ground strip, borrow firm joint device and above-mentioned coupling hole Joint, this ground strip tightly can be pressed solidly on the insulating body of electronic card coupler, and then guarantee its do not arch upward distortion or loosening phenomenon.
According to above-mentioned technical characterictic, wherein set coupling hole is a screwed hole on the insulating body, and be arranged on the two ends of insulating body, firm joint device then includes pressing article and fastener, wherein pressing article with respect to insulating body on set coupling hole place also be provided with through hole, fastener then is a fastener, in order to lock with screwed hole.
Another feature of the present utility model is: convexing with a projection on the insulating body with on the surface that pressing article matches, and be provided with a hole clipping at ground strip with respect to this projection place, borrowing this hole clipping and protuberance to fasten, ground strip is fitted on the insulating body.
Compared with prior art, advantage of the present utility model mainly is: can guarantee that ground strip can not produce arch upward distortion or loosening phenomenon, forming stable grounded circuit, and then can effectively prevent the interference of noise.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the three-dimensional exploded view of existing electronic card coupler.
Fig. 2 is the three-dimensional combination figure of existing electronic card coupler.
Fig. 3 is the cutaway view of Fig. 2 along the A-A line.
Fig. 4 is a three-dimensional exploded view of the present utility model.
Fig. 5 is a three-dimensional combination figure of the present utility model.
With reference to Fig. 4, shown in Figure 5, the utility model electronic card coupler mainly includes connector body 1, trip mechanism 2, ground strip 3 and firm joint device 4, wherein connector body 1 is made up of insulating body 11 and affixed thereon conducting terminal 12, and insulating body 11 convexes with a certain size projection 111 at its middle part, a surface that is parallel to conducting terminal 12 trends, and respectively is provided with a certain size coupling hole 112 (being screwed hole in the present embodiment) in the both sides of this projection 111.In addition, the two sides adjacent on this surface respectively are extended with two bearing rods 113 to same direction, to be used for affixed trip mechanism 2.
Trip mechanism 2, mainly by fixed frame 21, move back clamp 22, trace 23, saddle 24 and push rod 25 and formed, wherein saddle 24 is fixed on the fixed frame 21, and itself and fixed frame 21 common formation are accepted passage 26, and bearing rod 113 Joints of borrowing itself and connector body 1 both sides are so that whole trip mechanism 2 is thereon affixed.In addition, respectively be concaved with an electronic cards accepting groove 241, to be used to accommodate electronic cards (not shown) in the inboard of saddle 24.Move back clamp 22 and then be clipped between two saddles 24, and be provided with a draw-in groove 221 in the middle.23 of traces borrow a fulcrum 231 to be fixed on the fixed frame 21, and it can rotate around this fulcrum 231.And the one end is connected with push rod 25 formations, the other end is then borrowed a card 232 draw-in groove 221 mutually clamping set with moving back clamp 22 middle parts, like this, when external force acts on push rod 25, it will promote trace 23 and rotate and then drive around fulcrum 231 and move back clamp 22 motions and move back card motion to finish.
When assembling, borrow earlier on the trip mechanism 2 set set bearing rod 113 Joints in passage 26 and connector body 1 two ends of accepting so that trip mechanism 2 is fixed on the connector body 1, relend projection 111 set on hole clipping set on the ground strip 3 31 and the insulating body 11 and fasten and then ground strip 3 is fitted on the connector body 1.Then, on ground strip 3, be equipped with a pressing article 41, and make through hole set on through hole 411 on it and the ground strip 3 31 aim at set coupling hole 112 on the insulating bodies 11, and by fastener 42 and these coupling hole 112 Joints so that pressing article 41 is tightly pressed solidly on ground strip 3, firm to guarantee grounded circuit.
