Description
Technical field
The utility model is about a kind of electronic card coupler, especially about a kind of electronic card coupler with dustproof door.
Background technology
For preventing that dust from entering the electronic card coupler internal influence and being electrically connected stability, the spigot that existing electronic card coupler can insert at the power supply subcard as required is provided with a dustproof door.When electronic cards was not inserted, this dustproof door can be blocked in the socket front side made electronic card coupler inside be in the state of relative closure, thereby reaches the dustproof purpose.After electronic cards is inserted, can will prevent dust an ejection to its top, and can not influence the normal plant of electronic cards.
For guaranteeing the dustproof effect, dustproof gate open often contacts with shielding casing (or switching element) both sides (or a side) of electronic card coupler, thereby can there be bigger friction with the sidewall of shielding casing by its side in the electronic cards ejection uphill process when it, even dustproof door can't automatically reset after causing electronic cards to be extracted, the dustproof effect of influence.Even if maintain a certain distance, contact with the shielding casing sidewall and produce being subjected to still can to occur under the non-positive thrust of electronic cards or other the unexpected power effects dustproof door one side than friction situation greatly on dustproof reveal limit and shielding casing sidewall.
In view of the foregoing, existing electronic card coupler need be further improved, to guarantee the dustproof effect.
The utility model content
The purpose of this utility model just is to provide a kind of electronic card coupler, and the dustproof door of this electronic card coupler is that point contacts with the mode of face with transferring between the bridge, to reduce frictional force therebetween; Both guaranteed the dustproof effect, can guarantee again that electronic cards removed automatically reseting of the dustproof door in back.
For achieving the above object, the utility model provides following technical proposals: a kind of electronic card coupler, comprise a shielding casing, insulating body, some conducting terminal, dustproof doors that is contained in the insulating body, and the door that will prevent dust is fixed to the switching bridge on this shielding casing.Should comprise a pivot, at least one elastic component and at least one baffle plate by dustproof door.At least one side of this baffle plate has protruded out protuberance, and this protuberance contacts with switching bridge medial surface.
This elastic component is one to be sheathed on the torsion spring on the pivot.This switching bridge is provided with the pivoted hole of accommodating dustproof hingen axle.This switching bridge comprises shielding portion on, should go up the connecting portion that shielding portion extends certainly, reaches the fastener that extends from this connecting portion.This connecting portion is to extend vertically downward from last shielding portion both sides, and this fastener is to extending with the opposite end of electronic card coupler power supply subcard insertion from this connecting portion.At least one connecting portion is provided with the stopper section, and baffle plate is provided with first depressed part; This stopper section can be resisted against first depressed part.At least one connecting portion is provided with hole clipping, can pass for elastic component one end of dustproof door and with its fixing.Each connecting portion is provided with and the corresponding pivoted hole of dustproof door head lamp brush guard pivot.Each fastener comprises a base portion, reaches at least one support portion of extending from base portion.Base portion is provided with a spacing hole, is provided with first shell fragment that extends with respect to the electronic cards direction of insertion on the shielding casing sidewall, and second shell fragment that extends to the electronic cards direction of insertion, and this first shell fragment and second shell fragment are that this spacing hole is spacing.Shielding casing is provided with at least one last tabs that its sidewall extends downwards that is parallel to, and with at least one upwardly extending tabs down of its sidewall that is parallel to, it is spacing that the edge up and down of base portion is respectively on this tabs and following tabs.
Electronic card coupler of the present utility model is different with existing electronic card coupler, and its dustproof door is gone up the protuberance that contacts with switching bridge point is set.Thereby having good dustproof effect, frictional force is little between dustproof door and switching bridge, can automatically reset advantage.The utility model is from electronic card coupler is inner the fixture that is used for fixing to the circuit board to be installed in addition, thereby saves the space, helps the product miniaturization.
