Description

Electronic card coupler

[technical field]

The utility model is about a kind of electronic card coupler, especially refers to a kind of intensity that increases its trip mechanism, prevents the electronic card coupler that its trip mechanism lost efficacy.

[background technology]

Along with various card-type electronic assemblies such as memory card, electronic cards in different electronic installations, use increasingly extensive, can accommodate the card-type electronic assembly that is loaded with the data with different content at any time and realize that the electronic card coupler that telecommunication between these card-type electronic assemblies and electronic installation is transmitted also just becomes more important.As in " the Technology Analysis of Card Connector Performance " that published on June 19th, 2002 the 48th page to the 52nd page promptly disclosed this trend.Common electronic cards or memory card are because number of contacts is quite a lot of, so it is with after electronic card coupler docks, and need trip mechanism cooperation set on the electronic card coupler usually, could withdraw from outside the electronic card coupler easily and expediently.The trip mechanism of early stage electronic card coupler is the one-part form structure, that is move back card motion and can reach through promoting a push rod, and after electronic cards is inserted again, promptly can make push rod get back to preparation to move back the initial position of card, relevant prior art such as TaiWan, China patent announcement No. 325154, No. 314665 announcement.Yet, when electronic cards is inserted, because this type of one-part form trip mechanism must make its push rod end extend the outer quite length of computer casing, be easy to be subjected to the touching of improper external force and the damage that fractures, therefore, for improving this phenomenon, with the one-part form trip mechanism is that the basis has produced what is called " two-part " design of trip mechanism, relevant patent please refer to the TaiWan, China patent announcement No. 275121, United States Patent (USP) the 5th, 655, No. 918 and Chinese patent ZL99227777.9 case disclose, and the card motion that moves back of this trip mechanism mainly comprises two stages, promptly moves back card stage and reseting stage, so, moving back between card stage and the reseting stage, the push rod major part of trip mechanism is to be housed in the computer casing, and can exempt the risk that fractureed by touching.But also there is certain disappearance part in this kind two-part trip mechanism, owing to generally be provided with the guide channel of a heart on the combination section of this trip mechanism, when trip mechanism is in when moving back card or reseting stage, when the slide block of trip mechanism slides in this heart guide channel, can produce frictional force between the two, because of slide block is generally metal material, and this combination section is a plastic material, so through after the repetitive operation more repeatedly, can cause this guide channel to damage, thereby cause the two-period form trip mechanism to lose efficacy because of excessive abrasion.

[summary of the invention]

The object of the present invention is to provide a kind of electronic card coupler that increases trip mechanism intensity and prevent the trip mechanism inefficacy.

The object of the present invention is achieved like this: this electronic card coupler comprises insulating body, is contained in plurality of conductive terminals and trip mechanism in this insulating body.Wherein, the main part that this insulating body is provided with lengthwise reaches from extended two guid arms in these main part two ends, this trip mechanism is mounted on the insulating body, include the thrust unit that is mounted on guid arm and eject sheet, and thrust unit includes combination section, push rod and the connecting rod that can be mounted on the guid arm, wherein the combination section is provided with heart-shaped guide channel, this guide channel is the terrace structure of different depth, it is made up of stroke that plurality of sections connect to be provided with, and is equiped with the sheet metal that can be immobilizated in the combination section on the inwall of at least one section guide channel wherein.

Compared with prior art, the present invention has the following advantages: can increase the intensity of guide channel inwall by this sheet metal structure, thereby avoid the excessive abrasion of guide channel inwall and this trip mechanism was lost efficacy.
