Description

Technical Field

[0001] The utility model relates to the field of semiconductor testing, in particular to a connector with high-reliability contact. Background Art

[0002] Semiconductor testing is an indispensable link in the semiconductor industry chain. It runs through the entire product production and manufacturing process and plays a key role in improving production line yield and enhancing product competitiveness. The burn-in board is a specially designed test board used for long-term testing of electronic components and circuits to verify their performance and reliability. The connector is an important interface between the tester and the chip under test. It can realize the mutual transmission between the test signal and the chip under test. During the aging test process, the burn-in board needs to provide a stable electrical connection to ensure that the test signal can be accurately transmitted to the semiconductor device under test and receive its feedback signal. The connector is a key link in this transmission process, and its quality and performance directly affect the accuracy and reliability of the test.

[0003] During the use of existing connectors, when the connector is inserted into the aging board, there is a V-shaped docking slot inside. In this way, after the aging board is inserted, the top of the gold finger contacts the point, the contact surface is small, and poor contact is easy to occur. At the same time, due to plugging and unplugging, the slot spring is stretched open, and the force point is at the root, so the slot becomes looser and looser. In this way, the connector lacks the ability to make high-reliability contacts after long-term use. Poor contact of the connector will affect the accuracy of the test data. In addition, the connector cannot provide stable contact and will generate excessive current or voltage fluctuations, thereby damaging the semiconductor device to be tested.

[0004] Therefore, it is necessary to invent a connector with high-reliability contact to solve the above problems. Utility Model Content

It can ensure close contact between the gold finger and the spring, and reduce the risk of inaccurate test data or test failure due to poor contact. Since the spring is limited by the internal contact frame, it can ensure that the spring will not fail due to excessive deformation during long-term use. This design extends the service life of the connector, reduces the need for test interruption and reconnection due to damage to the connector, and improves the contact surface between the connector and the gold finger under long-term use. The design also has the advantages and benefits of enhancing the durability of the connector, improving test efficiency and enhancing safety, so as to solve the problem in the prior art that when the connector is used, when the connector is inserted into the aging board, there is a V-shaped docking slot inside.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides Figure 1-5 A connector with high-reliability contact shown includes a connector body 1, which is a connection body for burn-in board testing;

[0027] The front clamping cavity 2 is provided above the connector body 1 and is used to strengthen the connection with the aging board. The interior of the front clamping cavity 2 is provided with an aging board body 6, and the exterior of the aging board body 6 is fixedly mounted with a gold finger 7.

[0028] The top contact plate 8 is arranged inside the connector body 1 and is used to contact the aging plate body 6. The upper contact frame 9 of the slot is fixedly installed inside the connector body 1. The upper contact frame 9 of the slot is provided with a movable shaft 10 inside. The upper corrugated slot spring 11 is fixedly installed outside the movable shaft 10. The upper contact frame 9 of the slot is fixedly installed outside the extension plate 12. A telescopic spring 13 is provided on one side of the extension plate 12.

[0029] The lower contact frame 14 of the slot is arranged below the upper contact frame 9 of the slot to improve the contact with the gold finger 7, and a connecting shaft 15 is provided inside the lower contact frame 14 of the slot, and a lower corrugated slot spring piece 16 is fixedly installed on the outside of the connecting shaft 15. A fixing bolt 17 passes through the bottom of the connector body 1, and one end of the fixing bolt 17 is movably connected to a tail contact plate 18. A trapezoidal plug-in block 19 is fixedly installed above the tail contact plate 18. The trapezoidal plug-in block 19 is inserted from the bottom of the connector body 1. Due to the squeezing of the trapezoidal plug-in block 19, the lower corrugated slot spring pieces 16 that were originally loosely distributed at the lower ends of the aging board body 6 and the gold finger 7 on both sides are clamped in the middle, thereby completing the fixation of the aging board body 6 and the lower end of the gold finger 7. In this way, the connector has the ability of high-reliability contact, which can ensure close contact between the gold finger 7 and the spring piece, and reduce the risk of inaccurate test data or test failure due to poor contact.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, a clamping screw 3 is passed through the outside of the front clamping cavity 2, and a fixing knob 4 is fixedly installed at one end of the clamping screw 3, and a corrugated clamping plate 5 is provided at the other end of the clamping screw 3. After the aging plate 6 is inserted into the connector, the clamping screw 3 of the front clamping cavity 2 can be twisted to allow the two corrugated clamping plates 5 to clamp and fix the upper end of the aging plate 6. This can reduce the influence of the external aging plate 6 on the clamping contact inside the connector during the test. The number of contact racks 9 on the slots is set to multiple, and multiple contact racks 9 on the slots are arranged on the connector. The upper contact frame 9 of the slot is connected to the gold finger 7 of the aging plate body 6 through the upper corrugated slot spring piece 11, which strengthens the contact area of ​​the gold finger 7. The upper corrugated slot spring piece 11 is movably connected to the upper contact frame 9 of the slot, and the upper corrugated slot spring piece 11 is fixedly connected to the telescopic spring 13. Due to the continuous extension of the aging plate body 6, the upper corrugated slot spring piece 11, which was originally distributed in an inverted V shape due to the expansion and contraction of the telescopic spring 13, is compressed and contacts the upper end of the gold finger 7 of the aging plate body 6, thereby completing the fixation.

[0031] like Figure 1 、 Figure 4 and Figure 5As shown, the lower corrugated slot spring piece 16 is movably connected to the lower contact frame 14 of the slot, the tail contact plate 18 is fixedly connected to the connector body 1, and the trapezoidal plug block 19 is inserted from the bottom of the connector body 1. Due to the squeezing of the trapezoidal plug block 19, the lower corrugated slot spring pieces 16 that were originally loosely distributed at the lower ends of both sides of the aging plate body 6 and the gold finger 7 are clamped toward the middle, thereby completing the fixation of the lower ends of the aging plate body 6 and the gold finger 7. The number of trapezoidal plug blocks 19 is set to multiple, and the multiple trapezoidal plug blocks 19 are distributed at equal intervals on the tail contact plate 18. The structure of the trapezoidal plug block 19 is simple and the operation is simple. If a fault occurs, it is also convenient for maintenance personnel to replace it in time, thereby not delaying the normal use of the device.

[0032] The working principle of this utility model is: first take out the connector, align the aging plate body 6 with the opening of the connector body 1 and the front clamping cavity 2 for insertion. Due to the continuous extension of the aging plate body 6, the upper corrugated slot shrapnel 11, which was originally stretched and pressed together by the telescopic spring 13 and distributed in an inverted V shape, is compressed and presses against the upper end of the gold finger 7 of the aging plate body 6. Then, after the aging plate body 6 and the gold finger 7 press against the top contact plate 8, the trapezoidal plug block 19 is inserted from the bottom of the connector body 1. Due to the squeezing of the trapezoidal plug block 19, the lower corrugated slot shrapnel 16 that was originally loose at the lower ends of the aging plate body 6 and the gold finger 7 on both sides are clamped in the middle. Then, the fixing bolts 17 are tightened to strengthen the stability of the connection between the tail contact plate 18 and the connector body 1, thereby completing the fixation of the aging plate body 6 and the lower end of the gold finger 7, which gives the connector the ability of high-reliability contact. The force can ensure close contact between the gold finger 7 and the spring piece, reducing the risk of inaccurate test data or test failure due to poor contact. At the same time, since the spring piece is limited by the internal contact frame, it can ensure that the spring piece will not fail due to excessive deformation during long-term use. Then, before the connector is connected to the aging board 6 for testing, the clamping screw 3 of the front clamping cavity 2 can be twisted to adjust the spacing of the corrugated clamping plates 5, so that the two sets of corrugated clamping plates 5 can clamp and fix the upper end of the aging board 6. This can reduce the impact of the outside of the aging board 6 on the internal clamping contact of the connector during the test, thereby ensuring the stability of the test. Finally, after completing the installation and use of all connectors according to the above operations, the device can be maintained daily, and the use process of the connector with high-reliability contact is completed.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
