Description

Technical Field

[0001] This utility model belongs to the field of igniter technology, and in particular relates to a quick connection device for testing the electrical performance of an igniter. Background Technology

[0002] Although igniters vary greatly in their ignition methods and functions, each igniter generally contains an electrode plug. During igniter assembly, tests such as DC withstand voltage and insulation tests are required between the electrode plug pins and the housing to eliminate igniters with substandard electrical performance. Testing typically involves connecting a special plug to the igniter, with the other end of the plug connected to the testing equipment to bring out the electrode plug pins. Before testing, the plug pins (slots) must be manually aligned with the igniter's slots (pins), then pressed or screwed in completely. After testing, this process must be repeated, resulting in low production efficiency and the time-consuming and labor-intensive manual connection of the plug.

[0003] Due to the unique structure of igniters, there is limited research on their electrical performance testing. Most patents and literature focus on igniter testing equipment technology, with less emphasis on rapid connection between the igniter and testing equipment. For example, patent number 201410408798.8, "An Ignitioner Performance Testing System and Method," by patent applicant Hu Huihua, proposes a testing device capable of testing igniter operating voltage, operating current, and other performance characteristics, offering comprehensive testing functions, but lacks a method for rapid connection between the igniter and testing equipment. Similarly, Chinese patent number 202111005116.0, "A Universal Multi-Probe Connector for Vibration Insulation Testing of Detonators," by patent applicant Gong Du, designs a universal multi-probe connector that allows for rapid lead-out of electrode plug pins; however, it does not address how the outer casing connects to the testing equipment or the positioning of the igniter during testing, making it unsuitable for direct application in production.

[0034] The number of igniters, the number of flexible copper blocks, and the number of sets of flexible probes are all equal. Each igniter corresponds to one flexible copper block and one set of flexible probes, and there are 5-10 igniters. Each set of flexible probes includes four flexible probes.

[0035] In this embodiment, the positioning plate 3 is designed to hold 8 igniters 17 at a time, the pressure plate 2 is provided with 8 elastic copper blocks 12, and the probe holder 15 is provided with 8 sets of elastic probes 16.

[0037] In this embodiment, the probe holder 15 and the positioning plate 3 are designed as a universal structure. One specification can adapt to igniters 17 with a needle pitch of ±0.5mm. Only two specifications of probe holder 15 and positioning plate 3 are needed to meet the testing needs of conventional igniters 17.

[0040] The control box 5 has a built-in control module for the solenoid valve and power supply. The entire device is driven by the start button I7, start button II9, and emergency stop button 8 located on the surface of the machine base 4. The start button I7 and start button II9 are located on the left and right sides of the machine base 4, and the emergency stop button 8 is located in the middle. The upper cylinder 1 and lower cylinder 13 will only start to move after the tester presses the start button I7 and start button II9 with both hands at the same time, which effectively avoids the risk of mechanical injury. Therefore, there is no need to install a protective cover that would interfere with the handling of the igniter 17.

[0041] This embodiment uses two cylinders, one above the other, to replace the traditional screwing or pressing process of the test plug, significantly reducing the manual labor intensity of the testing process and improving the production efficiency. The elastic probe and elastic copper block designed in this embodiment are both elastic structures with a certain amount of expansion and contraction, which can ensure reliable contact between the shell and the negative electrode of the tester, and between the four electrode needles and the negative electrode of the tester. The device designed in this embodiment can hold multiple igniters for simultaneous testing at one time, which greatly improves the production efficiency. The probe holder and positioning plate designed in this embodiment are both universal structures, and only two specifications of probe holders and positioning plates are needed to meet the needs of conventional igniter testing.
