[0002] Connectors are also called connectors. Also known as joints and sockets in China, they generally refer to electrical connectors. They are devices that connect two active components, transmitting current or signals. The male and female ends of a connector are able to transmit information or current through contact, and are also called connectors. When testing the airtightness of a connector, a certain pressure is applied inside the connector and the pressure drop is observed to determine the connector's airtightness.

While increasing the detection cost, it also reduces the detection efficiency of large quantities of connectors. Based on the existing technical deficiencies, the present invention designs a connector air tightness detection device. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This connector air tightness detection device uses a sealing structure and a clamping structure. When performing an air tightness test, by pulling apart the pull rods on both sides, the spring contracts and the movable plate is driven to move inside the U-shaped vertical plate, thereby widening the distance between the two clamping plates. At this time, the connector is placed between the U-shaped vertical plates, and then the pull rods on both sides are loosened to quickly release the force of the springs on both sides. At this time, the two clamping plates are supported by the springs to clamp and fix the connector. Then, by driving the push cylinder, the telescopic rod drives the mounting plate forward. Since the soft silicone is soft in texture, it is squeezed and deformed when in contact with the connector port, thereby filling and blocking the connector port to prevent air leakage. This structure can adapt to connectors of different sizes through the deformation of the soft silicone, and can fix connectors of different sizes in combination with the clamping structure, thereby achieving the purpose of adapting the plugging to different connector ports and improving the detection efficiency; 1. This connector air tightness testing device uses a testing structure. When testing the air tightness of a connector, the connector is placed inside a U-shaped vertical plate, and its leads are passed through the through slots and through slots to connect to the testing tooling. Due to the design of the magnetic sheet and two slides, the testing tooling can be easily adsorbed and fixed on the magnetic sheet. At the same time, different types of testing tooling can be placed on the two slides to cope with different connectors, thereby improving the flexibility of the device. 2. This connector air tightness testing device uses a turntable and a clamping structure. When performing air tightness testing on connectors, four connectors are placed inside four U-shaped vertical plates respectively. After the test of one connector is completed, the lead can be unplugged, and then the turntable is rotated to align the next connector with the centering groove. In this way, serial testing of multiple connectors can be completed, reducing the idle time of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Wire grooves 52 are formed inside the four U-shaped vertical plates 51, and a top plate 57 is fixedly mounted on one end of the four limiting rods 56.

[0021] The soft silicone 35 can be deformed to adapt to connectors of different sizes, and can be fixed by cooperating with the clamping structure 5.

[0022] See also Figure 7-8 The detection structure 6 includes a base plate 61, with four columns 62 fixedly mounted on the top of the base plate 61, and a support plate 63 fixedly mounted on the top of the four columns 62. Slide rails 64 are fixedly mounted on both sides of the top of the support plate 63, and two slide platforms 65 are slidably mounted between the two slide rails 64. Magnetic plates 69 are fixedly mounted on the top of the two slide platforms 65, and detection tooling 68 is attracted to the top of the two magnetic plates 69.

[0023] Place the connector inside the U-shaped vertical plate 51, pass its leads through the through slot 66 and the through slot 67 to connect it to the detection tooling 68. Due to the design of the magnetic sheet 69 and the two slides 65, the detection tooling 68 can be easily adsorbed and fixed on the magnetic sheet 69. At the same time, different models of detection tooling 68 can be placed on the two slides 65 to cope with different connectors.

[0024] See also Figure 1-3 An L-shaped plate 2 is fixedly mounted on the top of the base 1. The L-shaped plate 2 is fixedly connected to the fixed plate 31. A centering groove 21 is formed on the top of the L-shaped plate 2. A rotating groove plate 22 is fixedly mounted on one side of the L-shaped plate 2. A turntable 4 is rotatably mounted inside the rotating groove plate 22. The turntable 4 is fixedly connected to the four U-shaped vertical plates 51 and the bottom plate 61.

[0025] After the inspection of one connector is completed, the lead can be unplugged, and then the turntable 4 is rotated to align the next connector with the centering groove 21, thereby completing the serial inspection of multiple connectors.

[0026] Working principle: When a connector air tightness detection device is used, first pull the two side rods 55 apart to make the spring 58 contract and drive the movable plate 53 to move inside the U-shaped vertical plate 51, thereby widening the distance between the two clamping plates 54. At this time, put the connector between the U-shaped vertical plates 51, and then loosen the two side rods 55 to quickly release the force of the two side springs 58. At this time, the two clamping plates 54 are supported by the springs 58 to clamp the connector. Then, by driving the push cylinder 32, the telescopic rod drives the mounting plate 33 to move forward. Since the soft silicone 35 is soft in texture, it is squeezed and deformed when it comes into contact with the connector port, thereby plugging the connector port. To prevent air leakage, the lead wires are passed through the through slot 66 and the through slot 67 and connected to the detection tooling 68. Due to the design of the magnetic sheet 69 and the two slides 65, the detection tooling 68 can be easily adsorbed on the magnetic sheet 69 and fixed. At the same time, different types of detection tooling 68 can be placed on the two slides 65 to cope with different connectors. At the same time, when the air tightness test of the connector is performed, the four connectors are placed inside the four U-shaped vertical plates 51 respectively. After the test of one connector is completed, the lead wires can be unplugged, and then the turntable 4 is rotated to align the next connector with the centering slot 21. In this way, the serialized test of multiple connectors can be completed, reducing the idle time of the equipment.
