Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a multi-functional relay test bench. Background Technology

[0002] Relays need to undergo aging tests and comprehensive tests before leaving the factory after production.

[0003] The main purposes of relay aging tests are as follows:

[0004] 1. Eliminate early failure products: During the relay production process, due to defects in raw materials, manufacturing process flaws, etc., some relays are prone to failure in the initial use. Through aging tests, the relays can be subjected to high stress in a short period of time, which accelerates the exposure of potential defects, thereby screening out problematic products in advance and improving the reliability of product use.

[0005] 2. Stable contact performance: The contact surface of a new relay may have slight unevenness or oxide layer, which will affect its contact resistance and switching performance. The repeated switching operations in the aging test can make the contacts rub and collide with each other, remove the surface oxide layer and impurities, and make the contact surface smoother and flatter, thereby reducing contact resistance, stabilizing contact performance, and ensuring stable transmission of signals and current.

[0006] 3. Optimize electromagnetic performance: The electromagnetic system of a relay may have problems such as unstable magnetic flux in the initial stage. During aging tests, repeatedly energizing and de-energizing the electromagnetic coil can fully magnetize the iron core, adjust the magnetic circuit characteristics, and allow the electromagnetic system to reach a stable working state, ensuring the accuracy and consistency of the relay's operation.

[0007] 4. Verify Design and Manufacturing Process: The rationality of the relay's design and manufacturing process directly affects its performance and reliability. Through rigorous testing, the rationality of the design and process can be verified to a certain extent, providing a basis for product improvement and optimization, and helping to improve the overall quality and competitiveness of the product.

[0008] Comprehensive testing measures the relay's parameters, including pull-in voltage, release voltage, coil resistance, overtravel, pull-in time, release time, and whether there is secondary pull-in.

[0009] Existing aging tests and comprehensive tests use different testing equipment with different fixtures, and the fixture can only test one relay at a time. After testing one relay, another relay is replaced. This type of testing device is inefficient. Summary of the Invention

[0010] The technical problem to be solved by this utility model is to provide a multi-functional relay test bench that can improve testing efficiency.

[0011] To solve the above-mentioned technical problems, the technical solution of this utility model is: a multi-functional relay test bench, including an upper clamping plate, a lower clamping plate, and a circuit board disposed between the upper and lower clamping plates. The upper clamping plate is provided with several sockets for inserting and fixing relays. The circuit board is provided with inserts corresponding to the sockets for electrical connection with the relays. The multi-functional test bench is provided with a test interface. The principle of this utility model is as follows: the multi-functional test bench can hold multiple relays for simultaneous testing, improving testing efficiency; the multi-functional test bench is composed of an upper clamping plate, a lower clamping plate, and a circuit board in the middle, with a simple structure and convenient assembly; the sockets on the upper clamping plate can mechanically fix the relays, and the sockets not only achieve electrical connection, simulating the actual tooling environment of the relays, but also provide a certain fixing force; the multi-functional test bench connects to aging testing equipment and integrated testing equipment through the test interface, and by switching tests, one test bench can correspond to two testing devices, improving testing efficiency.

[0012] As an improvement, the sockets are arranged in an array on the upper clamping plate, and the upper clamping plate is numbered according to the position of the sockets.

[0013] As an improvement, the upper clamping plate and the lower clamping plate are locked together by bolts and nuts.

[0014] As an improvement, the circuit board is provided with circuitry, a aging test component for aging tests, a comprehensive test component for integrated tests, and a switch for switching the usage status of the aging test component and the comprehensive test component. The aging test component is connected to the aging test interface, and the comprehensive test component is connected to the comprehensive test interface.

[0015] As an improvement, the aging test interface is connected to the aging test equipment, and the comprehensive test interface is connected to the comprehensive test equipment.

[0016] As an improvement, the lower clamping plate is provided with clearance grooves corresponding to the aging test component and the comprehensive test component.

[0017] The beneficial effects of this utility model compared with the prior art are:

[0018] The multi-functional test bench can hold multiple relays for simultaneous testing, improving testing efficiency. It consists of an upper clamp, a lower clamp, and a central circuit board, featuring a simple structure and easy assembly. The sockets on the upper clamp mechanically secure the relays, providing not only electrical connection and simulating the actual tooling environment of the relays, but also a certain level of fixing force. The multi-functional test bench connects to established testing equipment and integrated testing equipment via a test interface, allowing for one test bench to correspond to two testing devices through test switching, further enhancing testing efficiency.
