Description

Technical Field

[0001] This utility model relates to the field of terminal thrust testing technology, and in particular to a connector terminal thrust testing device. Background Technology

[0002] As a crucial component connecting connectors to external circuits, the reliability of connector terminals directly impacts the stable operation of the entire circuit system. In practical use, connector terminals are subjected to various external forces, with thrust being a common and significant one. If the terminals cannot withstand a certain thrust, it can lead to loose connections, poor contact, and ultimately circuit failures, affecting the normal operation of the equipment. With the rapid advancement of electronic equipment, the types and specifications of connectors are increasingly diverse, and different electronic devices have varying requirements for connectors. Existing testing equipment struggles to quickly adapt to the testing needs of various connector terminal specifications, lacking versatility and flexibility. Testing new connector terminal specifications often requires large-scale modifications or even replacement of the testing equipment, undoubtedly increasing R&D and production costs for enterprises. Furthermore, traditional testing equipment presents challenges in maintenance and upkeep; its complex structure and difficulty in disassembly result in high maintenance costs and long cycles, affecting the continuity and efficiency of testing work. Therefore, we have introduced a new connector terminal thrust testing device. Utility Model Content

[0003] The main objective of this invention is to provide a connector terminal thrust testing device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A connector terminal thrust testing device includes a base, with support legs fixedly installed at the four corners of the upper end of the base. A mounting base is fixedly installed at the upper ends of the four support legs. A controller is located on the left front end of the mounting base. A slot is provided at the front upper end of the mounting base. Movable grooves are provided on the inner front and inner rear walls of the slot. A limit mechanism is movably installed inside the two movable grooves. A placement device is movably engaged inside the slot. A support plate is provided at the rear upper end of the mounting base. A telescopic cylinder is fixedly installed at the upper rear end of the support plate. A push block is provided at the output end of the telescopic cylinder.

[0006] Preferably, the limiting mechanism includes a motor, a bidirectional lead screw is fixedly installed at the output end of the motor, a bearing is provided at the rear of the bidirectional lead screw, a driving plate is movably installed at both the front and rear of the outer surface of the bidirectional lead screw, a guide block is fixedly installed at the middle of the lower end of each of the two driving plates, and a limiting post is provided on the facing surfaces of the two driving plates.

[0007] Preferably, the rear part of the outer surface of the bidirectional lead screw is rotatably connected to the rear part of the mounting base via a bearing.

[0008] By adopting the above technical solution, the bidirectional lead screw is rotatably connected to the mounting base through a bearing, allowing the bidirectional lead screw to rotate flexibly within the mounting base.

[0009] Preferably, the placement device is located between two drive plates.

[0010] By adopting the above technical solution, the placement device is set between two driving plates, so that the driving plates can limit and function the placement device.

[0011] Preferably, the placement device includes a placement seat, the upper end of which is provided with a placement groove, the left and right ends of which are provided with handles, the lower end of which is provided with a positioning block, and the front and rear ends of which are provided with limit holes.

[0012] By adopting the above technical solution: the placement slot is used to place the connector terminal to be tested. Its shape and size can be designed according to the specific shape and size of the connector terminal, so as to position and fix the connector terminal, so that the connector terminal will not move at will during the test, ensuring the accuracy of the test. The handle makes it convenient for the operator to take out and install the placement seat.

[0013] Preferably, the placement seat is movably engaged inside the slot by a positioning block, and the position of the limiting hole corresponds to the position of the limiting post.

[0014] By adopting the above technical solution, the placement seat is movably engaged in the slot by the positioning block, making the installation and disassembly of the placement seat convenient and quick.

[0015] Preferably, the placement slot and the push block are positioned in a front-to-back correspondence.

[0016] By adopting the above technical solution, the placement slot and the push block are positioned in a corresponding manner, which ensures that the push block accurately acts on the connector terminal placed in the placement slot when the push force test is performed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Operators can easily grasp the handles at both ends of the placement base and engage it in the slot. Simultaneously, the controller allows for initial setup of the device and control of subsequent testing processes. For positioning, a bidirectional lead screw drives the moving plates to move in opposite directions, ensuring the limit pin accurately inserts into the limit hole, achieving precise positioning and fixation of the placement base. The placement slot corresponds to the push block position, ensuring the push block accurately acts on the connector terminal.

[0019] 2. When thrust testing is required for different types of connector terminals, simply restart the motor to reverse the bidirectional lead screw, causing the plate to move in opposite directions. The limit pin will then retract from the limit hole, allowing the operator to easily remove the mounting base for replacement. This adapts to the testing needs of various connector terminals, enhancing the device's versatility. Furthermore, the detachable design of the mounting base facilitates cleaning, maintenance, and replacement of damaged parts, reducing operating costs and maintenance difficulty, and extending the device's lifespan.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A connector terminal thrust testing device includes a base 1, with support legs 2 fixedly installed at the four corners of the upper end of the base 1. A mounting base 3 is fixedly installed at the upper end of the four support legs 2. A controller 4 is provided at the left front end of the mounting base 3. A slot 5 is provided at the front upper end of the mounting base 3. Movable grooves 6 are provided on the inner front wall and inner rear wall of the slot 5. A limit mechanism 7 is movably installed inside the two movable grooves 6. A placement device 8 is movably engaged inside the slot 5. A support plate 9 is provided at the rear upper end of the mounting base 3. A telescopic cylinder 10 is inserted and fixedly installed at the upper rear end of the support plate 9. A push block 11 is provided at the output end of the telescopic cylinder 10.

[0030] In this embodiment, the limiting mechanism 7 includes a motor 71, a bidirectional lead screw 72 is fixedly installed at the output end of the motor 71, a bearing 73 is provided at the rear of the bidirectional lead screw 72, a driving plate 74 is movably installed at both the front and rear of the outer surface of the bidirectional lead screw 72, a guide block 75 is fixedly installed at the middle of the lower end of each of the two driving plates 74, and a limiting post 76 is provided on the facing surfaces of the two driving plates 74; the rear of the outer surface of the bidirectional lead screw 72 is rotatably connected to the rear of the mounting base 3 through the bearing 73; the placement device 8 is located between the two driving plates 74.

[0031] With the above scheme: when the motor 71 starts, the output end of the motor 71 drives the bidirectional lead screw 72 to rotate. Since the front and rear of the bidirectional lead screw 72 have threads with opposite directions of rotation, the two drive plates 74 movably mounted on the bidirectional lead screw 72 will move towards or away from each other along the lead screw. The rear of the bidirectional lead screw 72 is rotatably connected to the rear of the mounting base 3 through the bearing 73, which ensures the stability of the rotation of the bidirectional lead screw 72. The guide block 75 in the middle of the lower end of the drive plate 74 plays a guiding role, so that the drive plate 74 moves smoothly. The limiting post 76 set on the facing surface of the drive plate 74 can be used to limit the operation of the docking plug terminal placement device 8. And because the placement device 8 is located between the two drive plates 74, the drive plate 74 can fix the position of the placement device 8 through the limiting post 76.

[0032] In this embodiment, the placement device 8 includes a placement seat 81, a placement groove 83 is provided at the upper end of the placement seat 81, handles 82 are provided at the left and right ends of the placement seat 81, and a positioning block 84 is provided at the lower end of the placement seat 81. Limiting holes 85 are provided at the front and rear ends of the positioning block 84. The placement seat 81 is movably engaged in the slot 5 through the positioning block 84, and the limiting holes 85 correspond to the positions of the limiting posts 76. The placement groove 83 corresponds to the front and rear positions of the push block 11.

[0033] Through the above scheme: the placement seat 81 is movably engaged in the slot 5 by the positioning block 84 at the lower end, which facilitates the installation and removal of the placement seat 81. The limiting holes 85 at the front and rear ends of the positioning block 84 correspond to the positions of the limiting posts 76. When the two driving plates 74 drive the limiting posts 76 to the appropriate position, the limiting posts 76 can be inserted into the limiting holes 85 to achieve the limiting and fixing of the placement seat 81. The handles 82 at the left and right ends of the placement seat 81 facilitate the operator to move and adjust the placement seat 81. The placement slot 83 is used to place the connector terminals and corresponds to the position of the push block 11. When the push force test is performed, the push block 11 can accurately act on the connector terminals placed in the placement slot 83 to ensure the accuracy of the test.

[0034] It should be noted that this utility model is a connector terminal thrust testing device. During use, by connecting the power supply and initializing the device via the controller 4, the operator holds the handles 82 at both ends of the placement seat 81, and the placement seat 81 is movably engaged in the slot 5 at the front of the upper end of the mounting seat 3 via the positioning block 84 at the lower end. The motor 71 in the limiting mechanism 7 is then activated. The output end of the motor 71 drives the bidirectional lead screw 72 to rotate. Because the threads on the front and rear surfaces of the bidirectional lead screw 72 rotate in opposite directions, the two driving plates 74 movably mounted on it move towards each other along the lead screw. The guide block 75 at the lower middle of the driving plate 74 slides within the movable groove 6, providing guidance and ensuring the smooth movement of the driving plate 74. As the driving plates 74 move towards each other, the limiting posts 76 on their facing surfaces gradually approach the placement seat 81 and insert into the limiting holes 85 at the front and rear ends of the positioning block 84, thus limiting and fixing the placement seat 81. The device is then used to test the thrust of the connector terminal. The connector terminal is placed in the placement slot 83 at the upper end of the placement base 81. The telescopic cylinder 10 at the upper rear end of the support plate 9 is activated by the controller 4. The output end of the telescopic cylinder 10 extends forward, pushing the push block 11 forward. Since the placement slot 83 and the push block 11 are positioned in a front-to-back correspondence, the push block 11 accurately acts on the connector terminal placed in the placement slot 83, applying a thrust to the connector terminal. Relevant data such as the magnitude of the thrust and the displacement of the connector terminal are observed and recorded during the test to evaluate the thrust performance of the connector terminal. After the test is completed, the telescopic cylinder 10 is controlled to retract, so that the push block 11 returns to the initial position. When it is necessary to perform thrust tests on different terminals, the motor 71 is restarted to reverse the bidirectional lead screw 72, causing the two drive plates 74 to move in opposite directions. The limit post 76 exits from the limit hole 85. The operator holds the handle 82 and removes the placement base 81 from the slot 5 to replace the placement base 81.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
