[0002] Connectors are important carriers for data and power exchange, and their waterproof performance directly affects the function and service life of products. With the rapid development of modern society and the continuous advancement of science and technology, people are paying more and more attention to the safety of various electronic products, and the quality and functional requirements of electronic products are getting higher and higher. As a carrier for data and power exchange between equipment and equipment, equipment and machines, and machines and machines, the importance of connectors is self-evident. The waterproof requirement of electronic products has become one of the basic elements of the quality of more and more electronic products, especially the connectors that carry wired data and power. The waterproof quality of it directly affects the function and life of the product. At the same time, with the diversification and complexity of the application environment of various electronic products, connectors with strong waterproof function will be applied to various fields around the world, such as security, communications, industry, aerospace and navigation, and military industry. Therefore, the improvement of waterproof technology will bring more reliable guarantees to equipment and machinery, and people will use electronic equipment and machinery more safely.

[0003] Existing connectors need to be used in a variety of environments, and some connectors need to work at higher temperatures, which accelerates the aging of the waterproof ring in the connector after being heated, and makes the waterproof ring easily deformed. At the same time, the insulating parts of the existing connectors do not have high temperature resistance, resulting in the connector being unable to work continuously at high temperatures for a long time, shortening the service life of the connector. Therefore, it is necessary to improve the existing connectors. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-temperature resistant waterproof connector includes an insulating body, a waterproof ring, an insulating plug and a plurality of terminals; the insulating body has an installation cavity, and the insulating body is made of a high-temperature resistant material; the waterproof ring is arranged in the installation cavity; the insulating plug is inserted into the installation cavity and is located above the waterproof ring, the insulating plug has an insertion cavity, the insertion cavity is connected to the installation cavity, and the insulating plug is made of a high-temperature resistant material; the plurality of terminals each include a contact portion, a fixing portion and a welding portion which are integrally formed in sequence, the contact portion extends into the insertion cavity, the fixing portion is buried in the insulating body, and the welding portion extends out of the insulating body.

[0007] As a preferred solution, the insulating body and the insulating plug are both made of high-temperature resistant plastic material, so that the terminals can be welded by reflow soldering.

[0008] As a preferred solution, the waterproof ring is made of high temperature resistant silicone material, which can withstand a high temperature of 260°C, while the commonly used waterproof ring can only withstand a temperature of 120°C.

[0009] As a preferred solution, both sides of the insulating body are provided with snap holes, and both sides of the insulating plug are provided with snap buckles, which are snap-fitted and fixed with the corresponding snap holes, so that the assembly of the insulating body and the insulating plug is more firm and reliable.

[0010] As a preferred solution, a vent hole is provided on one side of the insulating body, and the vent hole is communicated with the insertion cavity. When the connector and the plug-in are plugged in, air can be discharged through the vent hole, which is beneficial to the plug-in between the two.

[0011] As a preferred solution, a limiting groove is formed on the outside of the installation cavity, and a limiting rib is convexly provided on one side of the insulating plug. The limiting rib cooperates with the limiting groove to limit the position, effectively preventing the insulating plug from loosening after assembly.

[0012] As a preferred solution, a positioning column extends from the bottom of the insulating body, so that the installation position of the connector is more accurate.

[0013] As a preferred solution, a plurality of waterproof ribs are provided on the inner and outer sides of the waterproof ring to complicate the path for external moisture to enter the connector, thereby further enhancing the waterproof function.

The connector can continue to work at high temperatures for a long time, thereby extending the service life of the connector. A waterproof ring is arranged in the installation cavity to make the connector waterproof. In addition, the temperature is transferred to the waterproof ring through the insulating body and the insulating plug, thereby reducing the heat received by the waterproof ring, slowing down the aging of the waterproof ring, and making the waterproof ring less likely to deform. In addition, the fixing part is buried in the insulating body, thereby further enhancing the waterproof ability of the connector.
