Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a high-temperature and high-voltage resistant electrical connector. Background Technology

[0002] Electrical connectors are key components in electronic devices that enable circuit connections, and their connection reliability directly affects the normal operation of the equipment.

[0003] In related technologies, electrical connectors, as core electrical connection components, are used in fields such as new energy, aerospace, and industrial high-temperature equipment. They need to withstand high temperature and high pressure conditions for a long time. If the internal conductive components of the electrical connector experience abnormal temperature rise due to poor contact or overload, it can easily lead to faults such as insulation layer aging and breakdown, and metal component melting. It can even induce safety accidents such as fire and equipment shutdown. Therefore, it is necessary to use electrical connectors that can withstand high temperature and high pressure for electrical connection.

[0004] However, the design focus of existing high-temperature and high-voltage electrical connectors is mainly on thermal insulation (such as using thermal insulation materials such as ceramic fiber and aerogel) and high-voltage insulation (such as using alumina ceramic insulating sleeves), but they lack the ability to monitor the temperature of the core heat-generating components inside the connector (such as the cable core crimping point). As a result, when high-temperature anomalies occur in the cable core, routine inspections cannot detect them. To solve the above problems, a high-temperature and high-voltage electrical connector is proposed to address these issues. Utility Model Content

[0005] In view of this, the present invention provides a high-temperature and high-voltage electrical connector. The present invention transfers the heat of the cable core to the conductor by having the surface of the cable core in contact with the conductive ring. By having the other end of the conductor in contact with the probe of the temperature sensor, the temperature change can be quickly received by the temperature sensor, thereby monitoring the temperature change of the high-temperature and high-voltage electrical connector and enabling rapid repair when an abnormality occurs.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-temperature and high-voltage electrical connector, including a plug terminal at the front end of an insulated plug, a lead connector at the rear end of the insulated plug, a cable core connected to the rear end of the lead connector, a sleeve on the surface of the cable core, a waterproof cap detachably provided at the rear end of the sleeve, the sleeve including a front cylinder close to the insulated plug and a rear cylinder away from the insulated plug, a heat insulation pad provided inside the wall of the front cylinder, and a temperature detection device provided on the side wall of the rear cylinder.
