Description

Electronic card coupler

[technical field]

The utility model is about a kind of electronic card coupler, refers to a kind of notebook computer that is applicable to especially, but the connector of holding electronic card.

[background technology]

Along with the further miniaturization of the overall dimension of notebook computer, lighting, current notebook computer needs to store card by more external hanging type usually and reaches more, stronger function with cooperation, so the electronic card coupler that is exclusively used in the various electronic cards of winding is widely used in the notebook computer.Because notebook computer may use in dirty environment, dust or foreign matter can enter main frame inside by the socket of electronic card coupler like this, cause main frame inside unclean, thereby can influence the normal operation of notebook computer, even have a strong impact on the life-span of its use.And also the problems referred to above can appear in the process of carrying.So, on the basis of existing electronic card coupler, occurred again having cover members such as door or dust cap electronic card coupler to avoid occurring the problems referred to above.

United States Patent (USP) the 5th, 483 has disclosed a kind of electronic card coupler that covers door that has for No. 419.This patent disclosed covers the end that door is installed on the electronics card insert opening, and can be that the rotating shaft rotation is to reach the effect of opening and closing of fault electronics card insert opening with this end.In use, when needs inserted electronic cards, this covered to inner rotary, and socket is opened.After finishing using, this cover door more inwardly rotation cover this opening and do not enter into host computer inside by socket during plug-in card at electronic card coupler to prevent dust or foreign matter.But, because of covering, this has the excessive and unhandy defective of the radius of gyration, so it is another kind of as United States Patent (USP) the 6th that industry adopts at present usually, 120, that is disclosed for No. 322 covers door, it is by the socket both sides of the set rotating shaft crossbearer in two ends at electronic card coupler, and keep its not closed condition during plug-in card by spring, and when plug-in card owing to promoted by electronic cards, cover Men Huichao socket inner rotation and open, electronic cards is inserted smoothly, simultaneously spring strain under the thrust of electronic cards.When electronic cards withdraws from, cover door and under the effect of spring restoring force, return to its initial position with the sealing socket.But, because the existence of spring has at first increased the quantity of electronic card coupler building block, thereby has increased the manufacturing cost of this kind electronic card coupler; Next makes this kind electronic card coupler need add the step of one assembling spring when assembling, thereby has increased the complexity of this kind electric connector in assembling.

Therefore, necessary the aforementioned electronic card connector is improved to overcome the aforementioned disadvantages of prior art.

[utility model content]

Main purpose of the present utility model provides a kind of electronic card coupler, its simple in structure, simple and convenient assembly.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electronic card coupler include insulating body and some be contained in it and along front and back to the conducting terminal that extends.A pair of guid arm extends from the body two ends of insulating and therebetween is formed with the receiving space that is used to hold electronic cards.Shielding casing is mounted on the insulating body and extends back and is formed with the socket that the power supply subcard inserts, and wherein the opposite end in socket is respectively equipped with through hole, and also is provided with cantilever on shielding casing.Cover door frame and be located on the shielding casing and be shielded in described spigot, its two ends are provided with axostylus axostyle and are used for cooperating with above-mentioned through hole, also are provided with cam on the door in covering.When covering door frame and be located on the shielding casing, thereby this cam cooperates with cantilever and can make this cover Men Buhui to keep its closed condition when the plug-in card not with respect to shielding casing along the direction swing of extending perpendicular to its axostylus axostyle.

Compared with prior art, the utlity model has following beneficial effect: the closed state when cooperating between the cantilever by shielding casing and the cam that covers door replacing spring to reach keeping covering the Men Zaiwei plug-in card, both can reduce the building block of electronic card coupler, can reduce the number of assembling steps of electronic card coupler again.
