[0025] Reference Figure 1 、 Figure 2 , a traceless slot connector for U-DIMM burning, comprising a plastic core 1, a positioning member 2, a PIN foot spring 3 and a wedge-shaped component 4, wherein a cavity 11 is provided in the middle of the plastic core 1, and a mounting hole 12 is provided below the cavity 11, so as to facilitate the installation of the PIN foot spring 3 in the plastic core 1, and a plurality of the PIN foot springs 3 are symmetrically arranged in double rows in the cavity 11, so that the two sides of the gold finger on the memory module 6 are connected to the PIN foot spring 3 to ensure normal electrical connection to complete the burning of the U-DIMM; the upper end of the PIN foot spring 11 is in contact with the plastic core 1, the lower end of the PIN foot spring 1 is in contact with the side end of the mounting hole 12, and the positioning member 2 is clamped on the two opposite said The PIN foot spring pieces 3 are installed and limited between them; at the same time, the wedge-shaped component 4 is set above the positioning piece 2, and the wedge-shaped component 4 can move up and down to adjust the distance between the two PIN foot spring pieces 3. When the memory module 6 is inserted into the connector, the wedge-shaped component 4 moves up to expand the distance between the two PIN foot spring pieces 3, so that the distance between the PIN foot spring pieces 3 on both sides is greater than the width of the memory module 6. The PIN foot spring piece 3 loses the friction on the memory module 6, and the memory module 6 can be quickly inserted or pulled out to achieve seamless plugging and unplugging. Then, the wedge-shaped component 4 is controlled to move down so that the PIN foot spring pieces 3 on both sides release the elastic force and return to their original position. The two PIN foot spring pieces 3 clamp the gold fingers of the memory module 6 to ensure circuit connectivity.

[0026] Reference Figure 3In an embodiment of the present invention, a plug-in hole 13 is provided above the cavity 11, so that the memory module 6 can be inserted into the connector from the plug-in hole 13; limit blocks 14 are provided on both sides of the plug-in hole 13, and the upper end of the PIN foot spring 3 abuts against the limit blocks 14 to ensure that the upper end of the PIN foot spring 3 remains active. When there is no external force on the wedge assembly 4, the wedge 41 is lifted by the micro spring 42 and presses against the oblique edge of the PIN foot spring 3, so that the upper end of the PIN foot spring 3 can be fully opened, ensuring that the connection between the PIN foot spring 3 and the memory module 6 is deformed and the gap is opened so that the gold fingers of the memory module can be plugged in and out without scratches.

[0027] Reference Figure 3 、 Figure 4 In the embodiment of the present utility model, the PIN foot spring piece 3 is provided with a bent structure, and the PIN foot spring piece 3 includes a first abutting portion 31, a connecting portion 32, a second abutting portion 33 and a mounting portion 34 from top to bottom, wherein the first abutting portion 31 is provided with a vertical bent structure, so that the first abutting portion 31 abuts against the limiting block 14 to limit the PIN foot spring piece 3, thereby preventing the PIN foot spring piece 3 from being retracted inwardly due to its own elastic force and affecting the insertion of the memory module 6; the connecting portion 32 is provided with a vertical structure, and the distance between the connecting portions 32 of the corresponding two PIN foot spring pieces 3 is less than the hole pitch of the plug hole 13, which ensures that the PIN foot spring piece 3 does not When subjected to external force from the wedge-shaped component 4, it can clamp the gold fingers of the memory module 6, and increase the contact area between the PIN foot spring piece 3 and the gold fingers of the memory module 6, thereby ensuring normal electrical connection; the wedge-shaped component 4 abuts against the second abutting portion 33, and by lifting or pressing down the wedge-shaped component 4 to change the deformation of the PIN foot spring piece 3, the spacing between the connecting portions 32 of the two PIN foot spring pieces 3 is controlled, thereby realizing seamless insertion and removal of the gold fingers of the memory module 6; the mounting portion 34 is arranged in a horizontally bent structure, the mounting portion 34 is arranged in the mounting hole 12, and the mounting portion 34 is arranged between the positioning member 2 and the plastic core body 1, to fix the lower part of the PIN foot spring piece 3.

[0028] Specifically, the second abutting portion 33 includes a first inclined section 331, a vertical section 332 and a second inclined section 333. The first inclined section 331 is connected to the connecting portion 32, and the second inclined section 333 is connected to the mounting portion 34. The first inclined section 331 and the second inclined section 333 are all directed from the inside of the rubber core body 1 to the outside of the rubber core body 1, so that the distance between the corresponding two PIN pin spring pieces 3 gradually increases from the connecting portion 32 to the second abutting portion 33. At the same time, the distance between the vertical sections 332 of the two PIN pin spring pieces 3 is less than the width of the wedge-shaped member 41. When the wedge-shaped assembly 4 moves upward, the wedge-shaped member 41 can spread the two PIN pin spring pieces 3 apart so that the memory module 6 can be plugged in and out without leaving any mark, thereby avoiding problems such as wear and scratches on the gold fingers of the memory module 6.

[0029] Reference Figure 3 、 Figure 4 In an embodiment of the present invention, the wedge assembly 4 includes a wedge block 41 and a micro spring 42. The lower end of the wedge block 41 is inserted into the positioning block 2, and the micro spring 42 is arranged between the wedge block 41 and the positioning block 2. The two sides of the wedge block 41 abut against the two PIN foot springs 3.

[0030] Specifically, the wedge assembly 4 also includes a lock 5, and locks 5 are provided on both sides of the wedge block 41. By controlling the lock 5 to be pressed down or lifted, the wedge member 41 is actively controlled to be lowered or lifted, so that the connector has a fool-proof design to prevent the memory module 6 from being inserted before the PIN foot spring 3 spacing is opened, causing problems such as wear and scratches on the gold fingers of the memory module.

[0031] Specifically, the wedge block 41 is arranged in a T-shaped structure, and the wedge block 41 includes a contact block 411 and a plurality of plug-in blocks 412. The plurality of plug-in blocks 412 are arranged at intervals at the lower end of the contact block 411, and the micro spring 42 is sleeved on the plug-in block 412. When the lock buckle 5 is pressed down, the wedge piece 41 compresses the micro spring 42 to move downward. When the lock buckle 5 is lifted, the wedge piece 41 can be bounced up by the micro spring 42, so that the wedge piece 41 abuts against the PIN foot spring piece 3, thereby realizing the deformation of the PIN foot spring piece and changing the spacing of the PIN foot spring piece.

[0032] Specifically, a mounting through hole 21 is provided in the middle of the positioning member 2 , and the plug-in block 412 is plugged into the mounting through hole 21 to ensure the stability of the wedge-shaped component 4 during the upward or downward movement.

[0033] Specifically, chamfers are provided on both sides of the abutting block 411 to prevent the abutting block 41 from scratching the PIN pin spring 3 .

[0034] The working principle of the present invention is as follows: when in use, the connector is lifted by the elastic force of the micro spring 42 without the action of external force, and presses against the vertical end 332 of the second abutting portion 33 of the PIN foot spring piece 3, causing the PIN foot spring piece 3 to deform and increase the distance between the PIN foot spring pieces 3 on both sides. In this state, the memory module 6 is aligned with the plug hole 13 and inserted into the connector, and the lock buckles 5 at both ends are pressed down. The pressing action of the lock buckles 5 causes the wedge to descend and press against the second inclined section 333 of the second abutting portion 33 of the PIN foot spring piece 3, thereby releasing the elastic force of the PIN foot spring piece 3, causing the PIN foot spring piece 3 to return to its original position and closely contact the gold finger of the memory module 6, so that the memory module 6 is firmly locked in the connector, the circuit is connected, and relevant electrical tests can be carried out. After the test is complete, the latches 5 at both ends are lifted again. This lift causes the wedge 41, driven by the microspring 42, to rise again against the second inclined section 333 of the second abutment portion 33 of the PIN pin spring 3, causing the PIN pin spring 3 to deform and increase the spacing. This allows for easy removal of the memory module 6 without causing wear or scratches to the gold fingers. After removing the memory module 6, a new memory module 6 can be immediately inserted, and the above steps are repeated for the next round of testing, achieving efficient and lossless insertion and removal.

[0035] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
