Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a relay service life testing device. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity reaches the specified requirement, it is a device that makes the controlled quantity have a predetermined step change in the electrical output circuit. It has an interaction relationship between the input circuit and the output circuit and is usually applied to an automatic control circuit. In fact, it is an automatic switch that controls the operation of a large current with a small current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit. The service life test of the relay is to evaluate the fatigue resistance of the reed, ensure that the reed is not easily broken, and ensure that no abnormal situation occurs during the use of the relay. However, each test operation can only be carried out for a single reed, resulting in low test efficiency and test accuracy and being difficult to meet the requirements of a large number of test work.

The service life tests of multiple relays are carried out simultaneously through multiple test bases of a test board, so as to improve the test efficiency and test accuracy and meet the requirements of a large number of test work.

[0004] To achieve the above purpose, a relay service life testing device of the utility model includes a machine base, a test board arranged on the machine base, test bases arranged on the test board, and indicator lights electrically connected to the test bases. The test bases are provided with test pin positions. There are multiple test bases, and the multiple test bases are arranged along the length direction of the test board. There are multiple indicator lights, and the multiple indicator lights are arranged along the length direction of the machine base. The indicator lights are used to display the test results of the test bases.

[0005] Preferably, the machine base is provided with a pressing frame which is located above the test board and arranged along the length direction of the machine base. The pressing frame is used to abut and hold the top of the relay so that the terminals of the relay are inserted into the test pin positions.

[0006] Preferably, the machine base is provided with a receiving cavity for receiving the test board.

[0007] Preferably, the machine base is provided with a display and control buttons used in cooperation with the display.

[0015] The present utility model will be described in detail below with reference to the accompanying drawings.

[0016] As Figures 1 to 2 shown, a relay service life testing device of the present utility model includes a machine base 1, a test board 2 provided on the machine base 1, a test base 3 provided on the test board 2, and a display lamp 4 electrically connected to the test base 3. The test base 3 is provided with a test pin position 5. A plurality of test bases 3 are arranged along the length direction of the test board 2. A plurality of display lamps 4 are arranged along the length direction of the machine base 1. The display lamp 4 is used to display the test results of the test base 3.

[0017] The machine base 1 is designed with a test board 2. The test board 2 is installed with a plurality of test bases 3. Each test base 3 is provided with a test pin position 5. Each test base 3 uses a parallel circuit. By using the relationship of equal voltage, the coil terminals of the relays are connected in parallel, and a power supply is connected to provide voltage, so that the service lives of multiple relays can be tested simultaneously, with high accuracy, meeting the requirements of mass relay testing work. Since a plurality of display lamps 4 are respectively electrically connected to a plurality of test bases 3, the test conditions of multiple relays can be directly monitored, and the test results of the test base 3 can be visually displayed. That is, when the display lamp 4 lights up red, it means unqualified; when the display lamp 4 lights up green, it means qualified. It can also quickly locate the specific position of the relay with abnormal conditions, with high positioning accuracy. The present utility model performs the service life testing work on multiple relays simultaneously through a plurality of test bases 3 of the test board 2, improving the test efficiency and test accuracy, and meeting the requirements of mass testing work.

[0018] The base 1 of this embodiment is provided with a pressing frame 6, which is located above the test board 2 and arranged along the length direction of the base 1, and is used to press and hold the top of the relay so that the terminal of the relay is inserted into the test pin 5. Specifically, the pressing frame 6 is located above the test board 2, and the pressing frame 6 is arranged along the length direction of the base 1, so that the pressing frame 6 can press and hold the tops of multiple relays at the same time, so that the terminals of the relays are stably inserted into the test pin 5, ensuring that the positions of the multiple relays are not easily skewed and offset during the service life test, and ensuring the stability of the test work.

[0019] The machine base 1 of this embodiment is provided with a receiving cavity 7 for receiving the test board 2. Specifically, the test board 2 is inserted and received in the receiving cavity 7, so that the test board 2 is horizontally placed on the machine base 1, and then the test board 2 is correspondingly installed and fixed in the receiving cavity 7 using external screws. The number of test boards 2 used can be adjusted and increased according to actual work needs, and the operation is simple and convenient.
