Description

Technical Field

[0001] This utility model relates to the field of sealing test technology, specifically a sealing test fixture for chip connectors. Background Technology

[0002] A chip connector is a key component used to connect integrated circuit chips to printed circuit boards. It mainly provides electrical connection and mechanical fixation functions. It consists of an insertion component and a support component. The insertion component is connected to the support component by threads, which allows for quick installation, testing or replacement of chips without soldering, reducing maintenance costs.

[0003] In the chip connector manufacturing process, a sealing test is generally performed to ensure the chip connector is sealed. In the existing technology, when performing a sealing test on a chip connector, the chip connector is usually placed in an airtightness testing fixture for introducing gas, and then the sealing cover is sealed to the airtightness testing fixture. The sealing performance of the chip connector is detected by monitoring the change in gas pressure. However, the existing airtightness testing fixtures generally only hold one chip connector. Although a single chip connector can be carefully tested, the testing efficiency is low when testing a large number of chip connectors. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5As shown, in this embodiment, a chip connector sealing test fixture includes a sealing cover 1, with a moving end of a cylinder connected to the sealing cover 1. The cylinder controls the descent of the sealing cover 1, achieving spatial sealing inside the sealing test fixture 2 through contact with the sealing cover 1. The fixture also includes a sealing test fixture 2, with an air chamber 3 formed in the middle. An air inlet is provided on the air chamber 3, connected to an air pump via an air inlet pipe. A pressure sensor is installed on the air inlet pipe and electrically connected to a controller. The connection, function, and operating principle of the air inlet, air pump, air inlet pipe, pressure sensor, and controller are mature technologies in the prior art and will not be described in detail here. Partitions 4 are equidistantly installed inside the sealing test fixture 2, dividing the air chamber 3 into several compartments 5. The distance between two partitions 4 is adjustable. A rotating rod 6 is rotatably installed at the bottom of the sealing test fixture 2, with its middle fixed. The sealing test fixture 2 is equipped with a squeezing block 7. The inner wall of the fixture 2 has equally spaced slots 8 on both sides. A partition 4 is slidably installed between the two slots 8 on both sides. The distance between the two partitions 4 is adjusted according to different chip connector sizes. The partitions 4 divide the air chamber 3 into several compartments 5 that can accommodate chip connectors of corresponding sizes. The chip connector is placed inside the compartment 5. Then, the sealing cover 1 is lowered to control the sealing of the space inside the sealing test fixture 2. The controller then drives the air pump to operate and fill the air chamber 3 with gas. The air pressure sensor monitors the air pressure inside the air chamber 3 in real time to achieve sealing test of the chip connector. Several chip connectors of different sizes can be tested simultaneously, improving testing efficiency. After testing, the rotating rod 6 is rotated, and the squeezing block 7 on the rotating rod 6 squeezes and lifts the chip connector inside the compartment 5, allowing it to be removed for convenient use.

[0023] like Figures 1 to 5 As shown, the partition 4 includes a middle plate 41 and an end plate 42. Both ends of the middle plate 41 are symmetrically provided with limiting holes 9. A limiting rod 10 is symmetrically fixedly installed on one side of the end plate 42. The limiting hole 9 is slidably connected to the limiting rod 10. A first spring 11 is sleeved on the outside of the limiting rod 10. One end of the first spring 11 is fixedly connected to the end plate 42, and the other end of the first spring 11 is fixedly connected to one end of the middle plate 41. The bottom center of the middle plate 41 is recessed. A protrusion 12 is integrally provided on the top of the end plate 42. The end plate 42 is slidably inserted into the inside of the slot 8.

[0024] Press the protrusion 12 at the top of the end plate 42 towards the middle to control the end plate 42 to move closer to the middle plate 41. At this time, the first spring 11 is in a compressed state. Then, the partition 4 moves inside the air chamber 3. Then, the pressing protrusion 12 is released. The end plate 42 will be driven into the slot 8 by the push of the first spring 11, which is used to adjust the position of the partition 4.

[0025] like Figures 1 to 5 As shown, guide rods 13 are symmetrically welded inside the bottom end of the sealing test fixture 2, and the middle plate 41 is slidably installed between the two guide rods 13.

[0026] By moving the middle plate 41 along the trajectory of the guide rod 13, the movement of the partition 4 can be positioned.

[0027] like Figures 1 to 5 As shown, a positioning hole 14 is provided inside one end of the sealing test fixture 2 corresponding to the position of the rotating rod 6. One end of the rotating rod 6 can rotate and slide inside the positioning hole 14. A second spring 15 is sleeved on the outer side of one end of the rotating rod 6. One end of the second spring 15 is fixedly connected to the outer side of the rotating rod 6. The other end of the second spring 15 is fixedly connected to a connecting ring 16. The connecting ring 16 is slidably installed on the outer side of the rotating rod 6 and is in contact with the inner wall of the sealing test fixture 2. A vertical groove 17 and an inclined groove 18 are respectively provided on the inner wall of the end of the sealing test fixture 2 away from the positioning hole 14. The end of the rotating rod 6 can be stuck inside the vertical groove 17 and the inclined groove 18.

[0028] Push the rotating rod 6 to slide one end of the rotating rod 6 out of the inclined groove 18. At this time, the second spring 15 is in a compressed state. Then rotate the rotating rod 6. The pressing block 7 on the rotating rod 6 will press and lift the chip connector inside the dividing chamber 5. The chip connector can be lifted from inside the dividing chamber 5. When one end of the rotating rod 6 is rotated to a vertical state, the second spring 15 pushes the rotating rod 6 to drive one end of the rotating rod 6 to slide into the vertical groove 17, which can fix the rotation position of the rotating rod 6.

[0029] like Figures 1 to 5 As shown, the end of the rotating rod 6 near the vertical groove 17 and the inclined groove 18 is U-shaped.

[0030] This is used to make one end of the rotating rod 6 protrude from the inner wall of the sealing test fixture 2, so as to facilitate the operation of the rotating rod 6.

[0031] This utility model provides a chip connector sealing performance testing fixture, the specific working principle of which is as follows:

[0032] When using the device, adjust the distance between the two partitions 4 according to different chip connector sizes. Press the protrusion 12 at the top of the end plate 42 towards the middle, controlling the end plate 42 to move closer to the middle plate 41. At this time, the first spring 11 is in a compressed state. Then, move the middle plate 41 along the trajectory of the guide rod 13, which will drive the entire partition 4 to move along the guide rod 13. Then, release the pressing of the protrusion 12. The push of the end plate 42 by the first spring 11 will drive the end plate 42 to be inserted into the slot 8. The partitions 4 divide the air chamber 3 into several partition chambers 5 that can accommodate chip connectors of corresponding sizes. The chip connector will be placed inside the partition chamber 5. Then, control the sealing cover 1 to descend, which is used to control the sealing of the space inside the sealing test fixture 2. Finally, the controller drives the air pump to operate and push the air... Gas is filled into the cavity 3, and the gas pressure inside the cavity 3 is monitored in real time by a gas pressure sensor to achieve the sealing test of the chip connector. The sealing test can be performed on several chip connectors at the same time, improving the testing efficiency. After the test is completed, the sealing cover 1 is controlled to rise, and then the rotating rod 6 is pushed to slide one end of the rotating rod 6 out of the inclined groove 18. At this time, the second spring 15 is in a compressed state. Then the rotating rod 6 is rotated, and the pressing block 7 on the rotating rod 6 will press and lift the chip connector inside the dividing chamber 5, which can lift the chip connector from the dividing chamber 5. When one end of the rotating rod 6 is rotated to a vertical state, the second spring 15 pushes the rotating rod 6 to drive one end of the rotating rod 6 to slide into the vertical groove 17. People can then take out the chip connector inside the dividing chamber 5 for convenient use.
