Description

Electronic card coupler

[technical field]

The utility model is relevant a kind of electronic card coupler, refers to a kind of electronic card coupler with trip mechanism especially.

[background technology]

In recent years, various electronic cards are arranged all in the electronic equipments such as PDA and digital camera, these electronic cards equipment usually by the electronic card coupler that is provided with trip mechanism to realize release function to the electronic cards of having inserted.

Generally all include slide block in the existing trip mechanism with the common advance and retreat of electronic cards, insulating body, and part is contained in the spring in the slide block, borrow the elastic force of spring to push slide block during use and electronic cards is withdrawed from, along with electronic product is obvious day by day to the trend of compactization development, each assembly of trip mechanism also becomes thin short and small, the elastic force of spring will discharge when moving back card fully, this active force is to be carried in fully on the slide block, so card shows slightly thin slide block and is subjected to bigger impact again when withdrawing from, repeatedly use the as easy as rolling off a log damage of rear slider, in addition, for with the limit movement of slide block in certain scope, conduit or the slide rail that is used for limiting slide block also often is set on the insulating body bottom surface, bigger impulsive force also may be damaged these conduits or slide rail indirectly, and slide block accurately can not be located.Existing electronic card coupler majority is not provided with the mechanism of alleviating impulsive force, not can solve the bigger problem of the mutual impulsive force of each assembly of trip mechanism.Therefore, be necessary existing electronic card coupler is improved, to overcome

The defective of prior art.

[utility model content]

It is a kind of with low cost that the purpose of this utility model is to provide, and simple and convenient assembly can be alleviated the electronic card coupler of the greater impact power that slide block is subjected to.

For achieving the above object, the utility model adopts following technical scheme: a kind of electronic card coupler, comprise insulating body, be contained in conducting terminal in the insulating body, the shielding casing of coated insulation body and be installed in trip mechanism on the insulating body, this trip mechanism comprises sliding part and slide bar provided thereon, sliding part front top inboard has an inclined-plane, and the corresponding sliding part front end of insulating body place also has an inclined-plane.

Compared with prior art, the utlity model has following beneficial effect: the inclined-plane that sliding part front end inclined-plane is corresponding with insulating body can be in contact with one another and have certain frictional force, and decomposed the impulsive force of spring again to sliding part along the inclined-plane incline direction, thereby slowed down the impulsive force that sliding part is subjected to, and make slide block when the flex point by chute, be unlikely to damage chute, and with low cost, simple and convenient assembly.
