Abstract
A card edge connector comprises a lengthwise insulation body, a plurality of conductive terminals fixedly held in the insulation body and card-locking mechanisms for locking an electronic card. The insulation body is provided with a central slot which extends along the lengthwise direction and tower-shaped portions which are arranged at the ends of the insulation body and are used for accommodating the card-locking mechanisms. The central slot is provided with a fool-proofing portion for preventing the electronic card from inserting backward. Each card-locking mechanism is provided with a locking portion for locking the electronic card at the upper end and a pushing-back portion which protrudes into the central slot to push the electronic card back at the lower end. The central slot is provided with a slot bottom surface for the electronic card to insert and lean on. The pushing-back portion is provided with a lower surface which is lower than the slot bottom surface and a supporting contact surface which is higher than the slot bottom surface and is opposite to the lower surface and is used for preventing the wobbling of the electronic card after the electronic card is inserted in the right place of the central slot, so that the electronic card is guaranteed to be reliably fixed and held.
Description
[technical field]
The relevant a kind of bayonet connector of the utility model, the stable grafting of its subcard that is used for powering.
[background technology]
Bayonet connector mainly is installed on computer main frame panel with an internal memory electronic cards, to connect, thereby provides computer required memory body.Progress along with the epoch, people uprise the demand of bayonet connector thereupon, developed into the 4th present generation bayonet connector (DDR4 connector) from first generation bayonet connector originally, the bayonet connector of a new generation with respect to the bayonet connector in last generation in order to meet higher demand, usually numbers of terminals can increase, and then the electronic cards that connects with it also can correspondingly set up its golden finger number, and the contact engaging and separating force that so causes electronic cards to insert the bayonet connector connector increases.
Increase the problem of plug effort with golden finger in order to overcome electronic cards, the United States Patent (USP) US7 of Micron Technology Inc, 547, disclosed a kind of solution that reduces the plug effort problem of electronic cards and bayonet connector for No. 213B2, the two side portions that its design is compared the electronic cards lower edge by the mid portion setting the electronic cards lower edge is high, insert in the process of bayonet connector in electronic cards, the higher part in the centre of electronic cards is inserted in advance, then be the lower parts in both sides, so can effectively reduce electronic cards and insert the insertion force of bayonet connector.Yet when reducing the electronic cards contact engaging and separating force, new problem is following, i.e. easy double swerve after electronic cards insertion bayonet connector, may damage the golden finger of electronic cards and the conducting terminal of bayonet connector.
Therefore, be necessary to provide a kind of structure improved bayonet connector that has, to overcome above-mentioned defect.
