Technical Field
[0001] This utility model relates to the field of terminal clamp technology, specifically a power terminal insertion and extraction force testing fixture. Background Technology
[0002] The main purpose of testing terminal insertion and extraction forces is to simulate actual usage conditions and ensure that the terminals can maintain a stable connection when subjected to normal or unexpected forces. Insertion force refers to the force required to move the male and female terminals of a connector from a completely separated state to being inserted together, while extraction force is the minimum force required to separate the male and female terminals of the connected terminals, i.e., to pull them out.
[0003] However, existing power terminal insertion and extraction force test fixtures have the following problems during use: traditional clamping methods cannot fix terminals of different widths. In addition, clamping and adjusting are required during fixing, which requires a certain amount of labor. Furthermore, clamping and fixing can easily lead to stripping of the wires during pulling, thus failing to meet the stability requirements. Utility Model Content

[0018] Example 1, such as Figure 1-2 As shown, this utility model provides a technical solution: a power terminal insertion and extraction force testing fixture, including a fixture frame 1, a slide rail 2, and a moving block 6. The top of the fixture frame 1 is provided with the slide rail 2, and the moving block 6 is provided inside the slide rail 2. The top of the moving block 6 is provided with a female terminal fixing frame 7, and the male terminal fixing frame 7 and the male terminal fixing frame 3 are respectively inserted into the male terminal to be tested. The inner walls of the female terminal fixing frame 7 and the male terminal fixing frame 3 are provided with fixing mechanisms for fixing the male terminal and the female terminal. The fixing mechanism includes a moving groove 8 and a T-shaped pull rod 9. The inner walls of the female terminal fixing frame 7 and the male terminal fixing frame 3 are provided with the moving groove 8, and the T-shaped pull rod 9 is provided inside the moving groove 8. The outer wall of the T-shaped pull rod 9 is equipped with male terminal and female terminal insertion blocks 10 for fixing the position. A spring 11 is fitted on the outer wall, and the outer wall of the spring 11 fits against the inner wall of the moving groove 8. A threaded limiting block 12 is provided inside the insert block 10. The insert block 10 and the threaded limiting block 12 form a threaded connection structure. By pulling the T-shaped pull rods 9 on both sides, the threaded limiting block 12 is driven to retract into the moving groove 8, thereby compressing the spring 11 and tightening it. Then, the terminal is moved from top to bottom from the female terminal fixing bracket 7 until the bottom of the female terminal fixing bracket 7 is reached. After the threaded limiting block 12 is aligned with the terminal groove, the T-shaped pull rod 9 can be released. Under the elastic force of the spring 11, the threaded limiting block 12 is driven to insert into the terminal, completing the installation and fixing of the terminal. This structure is simple to operate and easy to install and disassemble. In addition, by rotating the threaded limiting block 12 to fit against the insert block 10, it is easy to install and fix terminals of different widths.
[0019] Example 2, as Figure 1-3 As shown, this utility model provides a technical solution: a power terminal insertion and extraction force test fixture, including a fixture frame 1 with a displacement mechanism inside for adjusting the distance between the female terminal fixing frame 7 and the male terminal fixing frame 3. The displacement mechanism includes a motor 4 and a lead screw 5. The motor 4 is provided on the inner wall of the fixture frame 1, and the lead screw 5, which passes through the moving block 6, is installed at the output end of the motor 4. The outer wall of the lead screw 5 meshes with the inner wall of the moving block 6. By starting the motor 4, the lead screw 5 is driven to rotate, thereby the lead screw 5 drives the moving block 6 to slide in the slide rail 2, thereby driving the position of the female terminal fixing frame 7 to the position of the male terminal fixing frame 3, and the male and female terminals are inserted.
[0020] Working principle: First, connect the external power supply. The operator can install the male and female terminals in the female terminal holder 7 and male terminal holder 3 respectively. By pulling the T-shaped pull rods 9 on both sides, the threaded limit block 12 is moved back to the moving groove 8, thereby compressing the spring 11. Then, the terminal is moved from top to bottom in the female terminal holder 7 until the bottom of the female terminal holder 7 is reached, so that the threaded limit block 12 is aligned with the terminal groove. Then, the T-shaped pull rods 9 can be released. Under the elastic force of the spring 11, the threaded limit block 12 is inserted into the terminal, completing the terminal alignment. The structure is easy to operate and disassemble. In addition, by rotating the threaded limit block 12 to fit into the insert block 10, it is easy to install and fix terminals of different widths. At this time, the motor 4 can be started to drive the lead screw 5 to rotate, so that the lead screw 5 drives the moving block 6 to slide in the slide rail 2, thereby driving the position of the female terminal fixing frame 7 to the position of the male terminal fixing frame 3, and the male and female terminals are inserted to complete the clamp movement task. In addition, by installing a sensor on the inside of the female terminal fixing frame 7, the tension received by the male terminal can be detected, and the detection result can be transmitted to the display for real-time viewing through an external microcontroller.
