Description

Electronic card coupler

The utility model is a kind of electronic card coupler, refers to have between a kind of shielding casing and insulating body the electronic card coupler of fixing locating effect especially.

In order to overcome the interference of electronics noise, usually one of mounted on surface at electronic card coupler has the quality of shielding casing to guarantee that telecommunication is transmitted of covering electronics noise function, as No. the 86210606th, TaiWan, China patent and United States Patent (USP) the 5th, 662, combining between the disclosed a kind of existing electronic card couplers of case such as No. 482, its shielding casing and insulating body locks mutually by bolts and nuts and to realize.As Fig. 5 and shown in Figure 6, shielding casing 80 front end both side edges respectively are provided with a locking plate 81, this locking plate 81 comprises the sidepiece 811 that forms from the vertical bending of shielding casing 80 lateral margins, and certainly these sidepiece 811 lower end marginal lappets directly bend form and with the parallel bottom 812 of shielding casing 80 plate faces, this bottom 812 is provided with through hole 813.When shielding casing 80 cooperates with insulating body 82 assemblings, described locking plate 81 can be placed in the nut containing hole 83 of relative set on the insulating body 82, and nut 84 is positioned on locking plate 81 bottoms 812,85 on bolt can pass its through hole 813 and cooperate with nut 84, thereby shielding casing 80 is locked on the insulating body 82.But, because described locking plate 81 is contained in the nut containing hole of insulating body in the mode of putting, there is no suitable fixing effect between it and this accepting hole, so, in the assembling process of shielding casing and insulating body, bolt is descended when group is gone into through hole up certainly, must can keep the position of shielding casing not to be moved by means of specific instrument, shielding casing be moved outward otherwise can cause locking plate to be ejected the nut containing hole.In addition; owing to there is no the fixing relation between locking plate and nut containing hole; thereby when electronic card coupler is assembled into host computer; cause in case the fixing between nut and bolt is unstable and to come off; shielding casing will inevitably break away from insulating body, causes the default defencive function that covers of electronic card coupler to lose.

The purpose of this utility model is, provide between a kind of shielding casing and insulating body and need not also can have preferable fixing locating effect, and can simplify assembling process, shorten and assemble man-hour by instrument, and can guarantee the ELECTROMAGNETIC OBSCURANT effect, improve the electronic card coupler of telecommunication transmission quality.

The purpose of this utility model is achieved in that electronic card coupler comprises main members such as insulating body, plurality of conductive terminals, shielding casing, trip mechanism and locking component, wherein the lateral margin place of shielding casing both sides respectively is provided with at least one locking plate, this locking plate can correspondingly be contained in the containing hole that is oppositely arranged on the insulating body, be primarily characterized in that: this locking plate is provided with interference device, and the side-walls of set containing hole then is provided with groove with respect to these interference devices on the insulating body.When the locking plate group is inserted containing hole, can borrow the groove of these interference devices and containing hole sidewall to reach fixing effect in the interference engagement mode.

According to above-mentioned feature, wherein locking plate comprises and vertically bends first sidepiece that extends and form from housing lateral margin place, and the bottom that forms and which is provided with through hole from this first sidepiece ora terminalis place towards horizontal direction bending extension, described interference device promptly is arranged on first sidepiece, and it comprises at least one the protruding thorn that is convex on the both side edges of being located at this first sidepiece.

Advantage of the present utility model is; when shielding casing is assembled on the electronic card coupler; need not can keep shielding casing to be stabilized on its former location by means of particular tool; make things convenient for the cooperation interlocking of bolts and nuts; even and bolts and nuts break away from; shielding casing also can keep the fixing relation with insulating body, can therefore not cause the forfeiture of covering defencive function.

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
