[0032] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0033] Please see Figures 1 to 3 The present invention provides a test pin card device for optical communication chips, comprising a positioning component 1, a pin plate component 2, a heat sink component 3, and a driving component 4.
[0034] The positioning component 1 includes a base 11 and a plurality of limiting blocks 12, with adjacent limiting blocks 12 spaced apart, and the limiting blocks 12 protruding from the upper surface of the base 11;
[0035] The needle plate assembly 2 includes a mounting sleeve 21 and a needle body fixing plate 22. The mounting sleeve 21 includes a body 211 and a plurality of protrusions 212. The plurality of protrusions 212 are disposed on the body 211 and extend in a direction away from the central axis of the body 211. The needle body fixing plate 22 is disposed on the body 211 and is used to support external needles 100.
[0036] One of the protrusions 212 is located between two adjacent limiting blocks 12;
[0037] The heat dissipation component 3 is disposed on the limiting block 12;
[0038] The driving component 4 is located on the base 11 and drives the needle body fixing plate 22 to move.
[0039] Specifically, in this embodiment, the positioning component 11 includes a base 11 and four limiting blocks 12. The limiting blocks 12 are arc-shaped and arranged in a ring array. The spacing between adjacent limiting blocks 12 is set, and each limiting block 12 is fixedly connected to the base 11. The needle plate component 2 includes a mounting sleeve 21 and a needle fixing plate 22. The mounting sleeve 21 includes a body 211 and four protrusions 212. The body 211 is hollow and ring-shaped. The four protrusions 212 are located on the outer surface of the body 211 and protrude from the outer surface of the body 211. Preferably, the body 211 and the four protrusions 212 are integrally formed. The needle fixing plate 22 is provided with a plurality of mounting holes. An external needle 100 is fixed to a mounting sleeve 211. Inside the hole, a needle fixing plate 22 containing a needle body 100 is fixed inside an mounting sleeve 21. Then, the mounting sleeve 21 is fixed to the base 11. One of the protrusions 212 is clamped by two adjacent limiting blocks 12 for fixing purposes. During operation, the driving component 4 drives the mounting sleeve 21 to move up and down, so that the needle body 100 comes into contact with the external chip to be tested. The setting of the needle fixing plate 22 allows several needle bodies 100 to rise and fall synchronously, applying the same external force to the surface of the external chip to be tested, thereby improving the detection accuracy. Preferably, a heat sink 3 is installed on the limiting block 12. The heat sink 3 is set close to the mounting sleeve 21 to dissipate the heat generated during operation in a timely manner, ensuring that the temperature during operation is within the preset range, thereby improving the detection accuracy.
[0040] By setting up a positioning component 1, a needle plate assembly 2, a heat sink 3, and a driving component 4, the positioning component 11 includes a base 11 and four limiting blocks 12. The needle plate assembly 2 includes a mounting sleeve 21 and a needle body fixing plate 22. The mounting sleeve 21 includes a body 211 and four protrusions 212. One protrusion 212 is located between two adjacent limiting blocks 12. The driving component 4 drives the needle plate assembly 2 to rise and fall, so that the external needles installed on the needle body fixing plate 22 rise and fall synchronously, thereby achieving the balance of detection pressure per unit area during the detection process. The heat sink 3 is set to dissipate the heat generated during the working process in a timely manner, ensuring the consistency of the detection environment and improving the detection accuracy.
[0041] The base 11 is provided with a central groove 110, a plurality of first grooves 111 and a plurality of second grooves 112. The central groove 110 is used to fix the body 211. The central groove 110 is connected to the second grooves 112. The first grooves 111 and the central groove 110 are spaced apart. One first groove 111 is located between two adjacent second grooves 112. The first groove 111 and the second groove 112 are connected. A limiting block 12 is embedded in a first groove 111 and a protrusion 212 is embedded in a second groove 112. The structure of the spacing between the first grooves 111 and the central groove 110 avoids assembly interference between the limiting block 12 and the body 211. At the same time, it avoids friction between the needle plate assembly 2 and the limiting block 12 during the lifting and lowering movement in the working state, which affects the firmness of the connection between the base 11 and the limiting block 12, and further improves the controllability of production quality.
[0042] The heat dissipation component 3 includes an outer plate 31, a top plate 32, and an inner plate 33 connected in sequence. The outer plate 31 and the inner plate 33 are located on the same side of the top plate 32. The outer plate 31 and the inner plate 33 are spaced apart. The limiting block 12 is engaged between the outer plate 31 and the inner plate 33. The heat dissipation component 3 is roughly U-shaped and distributed around the pin plate assembly 2 to achieve timely heat dissipation.
[0043] The distance between the inner panel 33 and the top panel 32 is greater than the distance between the outer panel 31 and the top panel 32, which facilitates higher identification during installation and improves the installation accuracy.
[0044] The body 211 is in the shape of a closed ring and has several through holes. The through holes penetrate the body 211 along its thickness direction. The needle plate assembly 2 also includes a clamping member 213. One end of the clamping member 213 abuts against the wall of the central groove 110, and the other end of the clamping member 213 abuts against the side surface of the needle fixing plate 22. Preferably, there are multiple through holes arranged in two rows. The through holes are close to the edge of the body 211. Each through hole is equipped with a clamping member 213. Both ends of the clamping member 213 protrude from the through hole. The axial direction of the clamping member 213 is parallel to the radial direction of the body 211. The clamping member 213 increases the connection between the body 211 and the central groove 110, and also increases the connection between the body 211 and the needle fixing plate 22.
[0045] The clamping member 213 includes a connecting member 2131 and a telescopic member 2132. The connecting member 2131 is disposed in the through hole. One end of the telescopic member 2132 is connected to the connecting member 2131. The telescopic member 2132 is slidably connected to the through hole and protrudes out of the through hole. There are two telescopic members 2132, which are located at the two ends of the connecting member 2131. The connecting member 2131 is located in the middle of the through hole. One telescopic member 213 abuts against the wall of the central groove 100, and the other telescopic member 213 abuts against the needle body fixing plate 22. The friction increases the connection between the body 211 and the needle body fixing plate 22 and increases the connection between the body 211 and the base 11.
[0046] The telescopic component 2132 includes a guide post 21321, a spring component 21322, and a movable head 21323. The connecting component 2131 is provided with a guide groove 21311, the axial direction of which intersects the central axis of the body 211. One end of the guide post 21321 extends into the guide groove 21311, and the other end is connected to the movable head 21323. Both ends of the spring component 21322 are connected to the movable head 21323 and the connecting component 2131, respectively. The spring component 21322 is sleeved on the guide post 21321. When the needle fixing plate 22 is inserted into the body... When the body 211 is in place, the movable head 21323 is pressed, the guide post 21321 slides into the guide groove 21311, and the spring 21322 is compressed, generating an elastic force that presses the movable head 21323 against the side surface of the needle body fixing plate 22, thereby improving the connection between the needle body fixing plate 22 and the body 211. When the body 211 is placed into the center groove 110, the movable head 21323 in contact with the center groove 110 is squeezed, the guide post 21321 slides into the guide groove 21311, and the spring 21322 is compressed, generating an elastic force that presses the movable head 21323 against the wall of the center groove 110, thereby improving the connection between the body 211 and the base 11.
[0047] The movable head 21323 is hemispherical, which facilitates the replacement of the needle fixing plate 22 and meets different production requirements.
[0048] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
