Description

Technical Field

[0001] This utility model relates to the technical field of automotive connection terminal equipment, specifically to a waterproof automotive connection terminal. Background Technology

[0002] Automotive connectors are components frequently encountered by electronic engineers. Their function is quite simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Automotive connectors come in a wide variety of forms and structures, but they are primarily composed of four basic structural components: contacts, housing (depending on the type), insulator, and accessories. In the industry, they are commonly referred to as sheaths, connectors, or plastic shells.

[0003] Automobile manufacturing uses a large number of connection terminals. Due to their different locations, some terminals are exposed to the outside. When the car is in motion, it will encounter rainwater. If the waterproof sealing of the terminals is poor, rainwater will seep in and cause short circuits. Moreover, the connection structure of most terminals is inconvenient to use. Utility Model Content

[0011] Preferably, the waterproof pad has a hollow groove inside, and a hollow rubber strip is fixedly installed inside the hollow groove.

[0012] Compared with the prior art, this utility model provides a waterproof automotive connector terminal with the following features:

[0013] Beneficial effects:

[0014] 1. This type of automotive waterproof connector terminal features a waterproof connector with enhanced waterproof performance. A sealing waterproof gasket is adhered to the inner side of the insert via waterproof adhesive. Multiple inserts are installed at one end of the waterproof gasket. During installation, the inserts are snapped into grooves inside the connector. The tightening action ensures the inserts are securely embedded within the grooves. Multiple springs are installed inside the waterproof gasket, using elasticity to compress and further seal the gasket. Hollow rubber strips are fixedly installed at the rear ends of the springs, providing flexible support and enhancing the waterproof effect of the connector during connection.

[0015] 2. This type of automotive waterproof connector terminal features a more convenient connection structure. The connector cylinder has fixed mounting blocks on both sides and fixed mounting blocks at the top and bottom. During installation, the insert is inserted into the connector cylinder, and the connecting plates on both sides are snapped into the outside of the mounting blocks. Rubber strips are movably installed at the top and bottom, with connecting holes inside the rubber strips. Pulling the rubber strips connects them to the mounting blocks, ensuring a tight connection between the insert and the connector cylinder, facilitating use and installation.
