Pressing plates and sliding assemblies are arranged on the two faces of the protective sleeve. The sliding assemblies are used for connecting the plates and the fastening assemblies. Wherein the guide wheels on the two sides of the pressing plate achieve accurate displacement control through rolling fit, and the sliding frame and the pressing plate achieve bidirectional synchronous movement through a parallelogram connecting rod mechanism. The bridging plate penetrating through the protective sleeve is connected with the sliding frame, so that the fastening bolt drives the sliding frame to move downwards along the embedding groove when rotating, the guide wheel is driven to translate from the sliding groove to the guide groove, and finally the two pressing plates are driven to synchronously clamp the side wall of the memory slot by a specified stroke. According to the structure, on the premise that stable contact of the golden fingers is ensured, the transverse clamping force after the memory bank is installed is improved, and low-delay and high-reliability operation under high-speed data transmission is achieved.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of memory bank structure, especially in a kind of high-speed low latency memory bank. BACKGROUND

[0002] In existing computer hardware architecture, the installation and fixation of memory bank generally depend on the mechanical hook structure arranged at both ends of slot. Specifically, refer to the attached drawings Figure 1 When memory bank is inserted into slot 1, the gold finger on both sides thereof is in contact with slot contact and is conducted, and the elastic hook 11 at both sides of slot is locked in slot by inward buckling action. This fixing mode is simple and adapts to existing standardized slot design, so it has application advantages in mass production.

[0003] However, the core problem of the technical scheme is that the contact stability of memory bank and slot is only realized by one-way mechanical constraint of hook, and the transverse clamping force is completely limited by the mechanical strength and deformation and rebound characteristics of hook. Since there is lack of multidirectional synchronous clamping mechanism between memory bank and slot, when the device is subjected to external vibration, temperature change or long-term plugging loss, the elastic deformation capacity of hook can gradually attenuate, resulting in micro-displacement between memory bank and slot contact. This displacement will destroy the close contact state of gold finger and contact, and then cause problems such as impedance rise of signal transmission path, fluctuation of electrical contact resistance, etc., eventually showing data transmission delay increase or instantaneous interruption. Especially in high-speed data transmission scene, the transverse constraint deficiency of traditional hook structure will directly threaten the reliability of system operation. SUMMARY
