Description

Technical Field

[0001] This utility model relates to the field of memory testing technology, specifically a high-frequency test spring. Background Technology

[0002] Memory testing refers to the multiple tests that memory undergoes during the manufacturing process. These tests include soldering inspection, PCB appearance inspection, functional testing, and overall appearance inspection. It also refers to software memory testing. This involves testing the software's maximum memory and other resource usage to prevent the software from exceeding system limits. Furthermore, it requires testing the software's behavior under extreme conditions, such as the behavior of a program running for an extended period when system memory resources are being consumed by other applications.

[0003] The Chinese patent website discloses a DDR5 high-frequency test spring, publication number CN220773976U. Although the memory module is inserted between the high-frequency springs, the metal contact points on both sides of the memory module contact the contact points on the high-frequency springs. The contact points on the high-frequency springs deform and compress backward, and the high-frequency springs simultaneously exert stable pressure on the PCB board and the memory module, ensuring stable contact and achieving stable conduction. After the test is completed, once the memory module is removed, the pressure on the elastic swing arm will be released, returning to its original state. The high-frequency spring adopts an integrated design with uniform wall thickness, no branching points in the signal transmission section, and a signal frequency that can reach 9.2GHz (@-3dB). It has a relatively large cross-section, low test impedance, and a short distance between the upper and lower contact points, which is beneficial for high-frequency signal transmission and reduces loss. However, the connecting plate and PCB board in this patent are connected using fixing bolts, requiring tools for disassembly, which is relatively cumbersome.

[0004] To address this, a high-frequency test spring is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-frequency test spring.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-frequency test spring, comprising:

[0008] PCB board;

[0009] A connecting plate is provided on the top of the PCB board, and a slot is provided on the top of the connecting plate;

[0010] A high-frequency spring is provided inside the slot;

[0011] The left and right outer walls of the connecting plate are provided with mounting grooves, and elastic swing arms are installed in the mounting grooves.

[0012] The PCB board and the connecting board are provided with fixing components at the front and rear ends, and the fixing components are used to connect and fix the PCB board and the connecting board.

[0013] The PCB board has a limiting hole at the top, and the connecting plate has a limiting post fixed at the bottom inside the limiting hole.

[0014] Preferably, the fixing component includes connecting ears that are respectively fixed to the front and rear ends of the PCB board, a locking strip is fixed to the top of the connecting ear, and connecting blocks are fixed to the front and rear ends of the connecting board. A slot is opened on the top of the connecting block, and the locking strip is engaged in the slot.

[0015] Preferably, the outer wall of the connecting block has a circular groove, the inner wall of the circular groove has a first locking hole that communicates with the locking groove, the outer wall of the locking strip has a second locking hole, a locking rod is locked in the first locking hole and the second locking hole, a receiving plate is fixed to one end of the locking rod, and a pull strip is fixed to one end of the receiving plate.

[0016] Preferably, a spring is provided on the outer wall of the clamp rod, one end of the spring is fixed to the receiving plate, and the other end of the spring is fixed to the inner wall of the circular groove.

[0017] Preferably, a limiting frame is fixed to the top of the connecting plate, and movable grooves are provided on the left and right inner walls of the limiting frame, in which limiting rollers are movably installed.

[0018] Preferably, the distance between the two limiting rollers is adapted to the length of the memory module.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] When disassembling the PCB board and connecting board, the operator only needs to manually pull the pull bar, which will move the locking rod. At this time, the spring will stretch accordingly. After one end of the locking rod disengages from the second locking hole, the operator can then manually drive the PCB board and connecting board to be disassembled. After the locking bar disengages from the locking slot and the limiting post disengages from the limiting hole, the PCB board and connecting board can be disassembled. Compared with the existing ones, the present invention is simpler and more convenient to disassemble the PCB board and connecting board without the need for any tools.

[0021] This invention features a limiting frame on the top of the connecting plate, with two limiting rollers inside the frame. Before the memory module is inserted into the slot, it enters the limiting frame in advance. The two limiting rollers limit the memory module, preventing it from being inserted into the slot due to height deviation at both ends. This also prevents the memory module from damaging the high-frequency contacts inside the slot. Furthermore, the limiting rollers can roll, allowing the memory module to be inserted into the slot more quickly, thus improving testing efficiency. Attached Figure Description

A retaining strip 9 is fixed to the top of the connecting ear 8. Connecting blocks 10 are fixed to the front and rear ends of connecting plate 2. A retaining groove 11 is provided on the top of the connecting block 10. The retaining strip 9 is engaged in the groove 11. A circular groove 12 is provided on the outer wall of the connecting block 10.

A second retaining hole 14 is provided on the outer wall of the retaining strip 9. A retaining rod 15 is engaged in the first retaining hole 13 and the second retaining hole 14.

One end of the spring 18 is fixed to the receiving plate 16, and the other end of the spring 18 is fixed to the inner wall of the circular groove 12.

[0031] Specifically, when disassembling the PCB board 1 and the connecting plate 2, the operator only needs to manually pull the pull bar 17. The pull bar 17 will drive the locking rod 15 to move. At this time, the spring 18 will perform a corresponding stretching movement. After one end of the locking rod 15 is disengaged from the second locking hole 14, the operator can then manually drive the PCB board 1 and the connecting plate 2 to be disassembled. After the locking bar 9 is disengaged from the locking groove 11 and the limiting post 7 is disengaged from the limiting hole 6, the PCB board 1 and the connecting plate 2 can be disassembled. Compared with the existing technology, the present invention is simpler and more convenient to disassemble the PCB board 1 and the connecting plate 2, and does not require any tools.

[0032] Example 2:

[0033] Please see Figure 1 This utility model provides a technical solution: a high-frequency test spring, with a limiting frame 19 fixed on the top of the connecting plate 2. The left and right inner walls of the limiting frame 19 are provided with movable grooves 20, and limiting rollers 21 are movably installed in the movable grooves 20. The distance between the two limiting rollers 21 is adapted to the length of the memory stick.

[0034] Specifically, this utility model provides a limiting frame 19 on the top of the connecting plate 2, and two limiting rollers 21 inside the limiting frame 19. Before the memory module is inserted into the slot 5, the memory module will enter the limiting frame 19 in advance. Under the action of the two limiting rollers 21, the memory module will be limited, preventing the memory module from being inserted into the slot 5 due to height deviation at both ends. This also prevents the memory module from damaging the high-frequency spring contacts inside the slot 5. Furthermore, the limiting rollers 21 can also roll, allowing the memory module to be inserted into the slot 5 more quickly, thus improving testing efficiency.

[0035] Working principle:

[0036] When disassembling PCB board 1 and connecting plate 2, the operator only needs to manually pull the pull bar 17, which will drive the locking rod 15 to move. At this time, the spring 18 will perform a corresponding stretching movement. After one end of the locking rod 15 is disengaged from the second locking hole 14, the operator can then manually drive PCB board 1 and connecting plate 2 to be disassembled. After the locking bar 9 is disengaged from the locking groove 11 and the limiting post 7 is disengaged from the limiting hole 6, PCB board 1 and connecting plate 2 can be disassembled. Compared with the existing ones, this utility model is simpler and more convenient to disassemble PCB board 1 and connecting plate 2 without the need for any tools.

[0037] By setting a limiting frame 19 on the top of the connecting plate 2, and setting two limiting rollers 21 inside the limiting frame 19, the memory module will enter the limiting frame 19 in advance before being inserted into the slot 5. Under the action of the two limiting rollers 21, the memory module will be limited, preventing the memory module from being inserted into the slot 5 due to height deviation at both ends, and preventing the memory module from damaging the high-frequency spring inside the slot 5. In addition, the limiting rollers 21 can also roll, so that the memory module can be inserted into the slot 5 more quickly, improving the testing efficiency.
