Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing tooling technology, specifically a testing tooling for the production and testing of rectifier diodes. Background Technology
[0002] A rectifier diode is a semiconductor device that converts alternating current (AC) into direct current (DC). It typically contains a PN junction and has two terminals: a positive terminal and a negative terminal. The most important characteristic of a diode is its unidirectional conductivity. In a circuit, current can only flow into the diode from the positive terminal and out from the negative terminal. During the manufacturing process of rectifier diodes, they need to be tested before leaving the factory, which involves the use of testing fixtures.
[0003] Existing testing fixtures for rectifier diode production lack a structure for storing and organizing the black and red test leads, making them prone to tangling and knotting when not in use. This results in low neatness of the fixture and inconvenience for future use. Furthermore, the height cannot be adjusted to accommodate different user heights, leading to low comfort during testing. Therefore, there is an urgent need for a new testing fixture for rectifier diode production to solve these technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a testing fixture for rectifier diode production and testing, in order to solve the problem mentioned in the background art that the existing testing fixture for rectifier diode production and testing lacks a structure for storing and organizing the black test probe and the red test line probe, which makes them prone to tangling and knotting when not in use. This results in low neatness of the testing fixture and inconvenience for future use. In addition, the height cannot be adjusted according to the different heights of different users, resulting in low comfort during testing.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A testing fixture for rectifier diode production includes a testing platform and a base. The testing platform is connected to the top of the base, and casters are connected to both sides of the bottom of the base. Brakes are installed on the casters. A lifting platform is embedded in the center of the top of the testing platform, and a central support is connected to the center of the top of the lifting platform. Left and right support seats are connected to the top of the lifting platform on the left and right sides of the central support seat, respectively. A testing upright plate is connected to the upper left end of the testing platform, and a caster is mounted on the front surface of the testing upright plate. The multimeter has a red probe connected to one terminal and a black probe connected to the other terminal. A support platform is connected to the bottom of the base, and an electric push rod is mounted on the top of the support platform. The top of the electric push rod passes through the bottom of the testing platform and connects to the bottom of the lifting platform. An upper storage rack is connected to the right side wall of the testing platform, and a lower storage rack is located below the upper storage rack.

[0023] Please see Figure 1-5A testing fixture for rectifier diode production testing includes a testing platform 15 and a base 1. The testing platform 15 is connected to the top of the base 1, and casters 2 are connected to both sides of the bottom of the base 1. Brakes are installed on the casters 2. A lifting platform 12 is embedded in the middle of the top of the testing platform 15, and a middle support 3 is connected to the middle of the top of the lifting platform 12. A left support 5 and a right support 4 are connected to the top of the lifting platform 12 and to the left and right sides of the middle support 3, respectively. A testing upright plate 6 is connected to the upper left end of the testing platform 15, and a multimeter is installed on the front surface of the testing upright plate 6. 7. One terminal of the multimeter 7 is connected to a red probe 8, and the other terminal of the multimeter 7 is connected to a black probe 11. The bottom of the base 1 is connected to a support platform 14. An electric push rod 13 is installed on the top of the support platform 14. The top of the electric push rod 13 passes through the bottom of the testing platform 15 and is connected to the bottom of the lifting platform 12. An upper storage rack 10 is connected to the right side wall of the testing stand 6. A lower storage rack 9 is set below the upper storage rack 10. The red probe 8 is wound back and forth on the upper storage rack 10, and the black probe 11 is wound back and forth on the lower storage rack 9.
[0024] The number of casters 2 is set to four, and the four casters 2 are arranged in pairs facing each other about the bottom of the base 1.
[0025] The lifting platform 12 and the testing platform 15 are in contact, but they are not connected.
[0026] The top of the base 1 is open.
[0027] The left support seat 5 and the right support seat 4 are arranged symmetrically about the middle support seat 3.
[0028] The upper storage rack 10 and the lower storage rack 9 have the same shape and structure.
[0029] The working principle and usage process of this utility model are as follows: First, during testing, place the two leads of the rectifier diode in the grooves on the left support 5 and the right support 4 respectively, and place the middle part of the rectifier diode in the groove of the middle support 3. Then, set the multimeter 7 to the high resistance range, connect the red probe 8 to the negative terminal of the diode, and connect the black probe 11 to the positive terminal to measure its reverse resistance. Under normal circumstances, the reverse resistance of the rectifier diode should be very high, close to infinity. If the reverse resistance is very low, it indicates that the diode has a large reverse leakage current, which may be faulty. By setting up the upper storage rack 10 and the lower storage rack 9, the red probe 8 can be wound back and forth on the upper storage rack 10 for neat storage, and the black probe 11 can be wound back and forth on the lower storage rack 9 for neat storage. This can prevent the black probe 11 and the red probe 8 from getting tangled when not in use, making the testing fixture neat and easy to use next time.
[0030] The electric push rod 13 drives the lifting platform 12 to move upward, thereby adjusting the height according to the different heights of different users, which improves the comfort during the test.
