Description

Card Edge Connector Positioning Device

technical field

A card edge connector positioning device is arranged beside the memory slot to clamp and fix the memory for positioning.

Background technique

The operation of computer equipment must have random access memory (RAM) to help the data access and movement of computer calculations, and most computer equipment has memory slots for pluggable random access memory (also known as memory) Insert, and the random access memory (hereinafter collectively referred to as memory) must be firmly fixed in the memory slot in order to avoid the problem of poor contact, access error or memory damage caused by displacement, so a pair of positioning devices are arranged beside the known memory slot to Clamp the memory so that it will not shake, and a plurality of connection terminals (Pin) will be set in the memory slot and extend to the outside of the memory slot to connect with a circuit board. The lower edge of the positioning device must be connected to the plurality of connection terminals (Pin). ) must be located on the same horizontal plane to be correctly assembled, and the manufacturing error of the positioning device and the multiple connecting terminals (Pins) must be controlled within a very small range, which leads to difficulties in production; the previously applied Chinese Taiwan Patent Publication No. 555107 In the "Structure Improvement of Memory and Network Card Connectors (1)" of No. 1, the memory slot in this utility model has a positioning device on both sides of the memory slot to clamp the two sides of the memory, but since the positioning device is mostly plastic injection, and then Connected to both sides of the memory slot, there are errors in the processing process, and the accuracy of the two positioning devices is different, and the positioning device is a flexible component. After the memory is inserted and pulled out many times, the positioning device is pushed out and displaced. It will cause permanent deformation of the positioning device due to external force, thus generating errors and affecting the positioning ability of the memory; and a previous utility model such as the "card edge connector" of Taiwan Patent Publication No. The production difficulty of the same horizontal plane of the device and the plurality of connecting terminals (Pin) makes a space reserved between the memory slot and the positioning device, so that the positioning device has a space to move up and down before being fixed on the circuit board, so Even if the positioning device can tolerate manufacturing errors and make the lower edge of the positioning device on the same level as the plurality of connecting terminals (Pins), the reserved space also makes the positioning device shake left and right in addition to moving up and down. The left and right positions of the device will make it difficult to insert the memory and directly increase the defect rate; therefore, the structure of the fixed memory still needs to be improved.

Utility model content

In view of the deficiencies of the above-mentioned known utility models, the main purpose of the utility model is to provide a structure for positioning after the memory is inserted, so as to enhance the positioning capability and reduce the force deformation of the positioning device.

It can be seen from the above that in order to achieve the above purpose, the utility model provides a card edge connector positioning device, which is located on both sides of the memory slot, and the positioning device at least includes a first limiting groove, a second limiting groove and The support member, wherein the first limiting groove is closer to the end of the positioning device relative to the second limiting groove, the supporting member has a first end edge and a second end edge on opposite sides, and the first end edge is embedded In the first limiting groove, the gap between the first end edge of the support member and the first limiting groove is extremely small to form a displacement fulcrum, and the second end edge on the other side of the support member is at the second In the limiting groove, and the gap between the second end edge and the second limiting groove is greater than the gap between the first end edge and the first limiting groove, so that the second end edge is in the second limiting groove The displacement stroke is much larger than the displacement stroke of the first end edge in the first limiting groove, so that the supporting member has a displacement space allowing assembly errors.
