Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an impact-resistant sealed connector and a sealing capability detection method thereof. Background Art

[0002] A connector, also known as a plug-in connector, is an electronic component used to connect two active devices to transmit current or signals. It typically consists of a male end (plug) and a female end (socket), connecting and disconnecting the circuit. Basic connector performance includes mechanical, electrical, and environmental performance. Mechanical performance includes factors such as insertion and removal force and mechanical life. Electrical performance includes contact resistance, insulation resistance, and dielectric strength. Environmental performance includes resistance to temperature, humidity, salt spray, vibration, and shock.

[0003] In existing sealed connectors, after long-term use, their sealing performance will decrease as the number of plugging and unplugging increases. In addition, during the multiple plugging and unplugging process, the connector will also be impacted, causing damage to the plug or socket, thereby reducing the sealing performance and service life.

The waterproof switch 109 is electrically connected to the circuit board block 105, and the electromagnet 106 is electrically connected to the waterproof switch 109. The on and off of the waterproof switch 109 is used to control the on and off of the electromagnet 106, thereby realizing the extension and retraction of the iron block 108.

[0019] The connector assembly 2 includes a plug 201, a wedge groove 202, a card hole 203, an insert 204, an air groove 205, an air hole 206 and a connecting wire head 207. The side walls of the plug 201 are provided with wedge grooves 202. There are multiple wedge grooves 202 and they are symmetrically distributed on the plug 201. The wedge block 104 is engaged with the wedge groove 202 to improve the impact resistance during plugging and unplugging. The inside of the wedge groove 202 is provided with a card hole 203. There are multiple card holes 203 and they are all located on the plug 201. The iron block 10 8 is connected to the plug 201 through the card hole 203. When the iron block 108 is extended, it can be inserted into the card hole 203, thereby fixing the plug 201 to the socket body 101.

[0021] A method for testing the sealing ability of an impact-resistant sealed connector comprises the following specific steps: S1. First, take a connector and perform a self-test. Plug the connector assembly 1 and the connector assembly 2 together. The inflatable seal ring 301 is clamped between the air groove 205 and the inner and outer limit rings 102 and 103. Inflate the air through the air nozzle 302. The wedge block 104 is clamped in the wedge groove 202. The insert 204 is inserted into the socket. S2. Press the waterproof switch 109 to cut off the power to the electromagnet 106. The iron block 108 pops out of the wedge 104 under the action of the spring 107 and engages with the clamping hole 203 on the plug 201. S3. Then observe whether there are obvious gaps on the outer surface of the connector. If there are obvious gaps, the airtightness is largely problematic and there may be leakage. Otherwise, there is no gap. S4. Take another connector and place a wireless air pressure sensor inside the inner limit ring 102 of the socket body 101. The wireless air pressure sensor is connected to the external detection instrument signal; S5. Then, the connector assembly 2 and the connector base assembly 1 are plugged together. The inflatable sealing ring 301 is clamped between the air groove 205 and the inner and outer limiting rings 102 and 103. Air is then inflated through the air nozzle 302. The wedge block 104 is clamped in the wedge groove 202, and the insert 204 is inserted into the socket. S6. Press the waterproof switch 109 again to cut off the power to the electromagnet 106. The iron block 108 pops out of the wedge 104 under the action of the spring 107 and engages with the clamping hole 203 on the plug 201. S7. Place the connected connector in a test box and seal the test box, wherein one side of the test box is connected to an air pump; S8. Start the air pump, and then use an external detection instrument to observe the internal air pressure value of the connector detected by the wireless air pressure sensor. If the external detection instrument shows a change in the internal air pressure value, it means that there is air leakage inside the connector, indicating poor air tightness. On the contrary, if the detected air pressure value does not change, it means that there is no air leakage inside the connector and the air tightness is good. S9. After plugging and unplugging the connector several times, insert the wireless air pressure sensor again for a second test. Observe the air pressure value detected by the internal wireless air pressure sensor in the same way to determine its sealing performance.

[0022] Working principle: The connector assembly 2 and the connector assembly 1 are plugged in, the inflatable sealing ring 301 is clamped in the air groove 205 and between the inner limit ring 102 and the outer limit ring 103, and is inflated through the air nozzle 302 to expand the inflatable sealing ring 301, the wedge block 104 is clamped in the wedge groove 202, the plug 204 is inserted into the socket, and then the waterproof switch 109 is pressed to cut off the power to the electromagnet 106. The iron block 108 pops out of the wedge block 104 under the action of the spring 107 and is clamped with the clamping hole 203 on the plug 201, thereby fixing the plug 201 to the socket body 101. When the plug 201 needs to be unplugged, press the waterproof switch 109 to energize the electromagnet 106, thereby generating a magnetic field, attracting the iron block 108 into the inside of the wedge block 104, and compressing the spring 107 at the same time, so that the plug 201 can be unplugged.
