Description

Waterproof Connector

technical field

The utility model relates to a connector, in particular to a waterproof connector with inner and outer waterproof rings integrally formed.

Background technique

Various electronic products can transmit and receive each other through connectors, so connectors have been widely used in the computer industry and home video and audio equipment. Users can use the settings of the connectors to transmit the required data or Signal.

Generally, when electrical products are placed outdoors or in an environment with a lot of moisture, their connectors are prone to moisture and affect electrical conduction, which in turn leads to damage to electrical products. In particular, there are often gaps in the assembly structure of the plug or socket, and water vapor easily penetrates into the interior of the connector through the gaps. Therefore, the waterproof structure of the connector is particularly important.

The waterproof structure of the existing connector is to set an outer waterproof gasket on the outside of the metal shell, or to set an inner waterproof gasket between the inside of the socket and the metal shell, by setting the inner waterproof gasket and the outer waterproof gasket. Make sure that water or moisture from the external environment cannot seep into the connector. However, the aforementioned inner waterproof gasket and outer waterproof gasket are separately installed, and the assembly steps are cumbersome; in addition, gaps are likely to occur between the inner waterproof gasket and the outer waterproof gasket, causing water or moisture to easily leak from the inner waterproof gasket and the outer waterproof gasket. The gap between the connectors seeps into the connector, resulting in loss of waterproof function.

In view of this, the present inventor intends to improve and solve the above-mentioned shortcomings. Naite has devoted himself to research and combined with theoretical application, and finally proposes a utility model with reasonable design and effective improvement of the above-mentioned shortcomings.

Detailed ways

The detailed description and technical content of the present utility model are described below with drawings, but the attached drawings are only for reference and illustration, and are not intended to limit the present utility model.

Please refer to FIG. 1 to FIG. 3 , which are respectively a three-dimensional appearance schematic diagram of the waterproof connector of the present invention and a combined cross-sectional view of two sides. The waterproof connector 1 of the present invention includes a connector body 10 , a plurality of conductive terminals 20 and a waterproof cover 40 . The conductive terminals 20 are disposed on the connector body 10 to be plugged with another connector to provide electrical connection. The waterproof cover 40 is combined with the connector body 10 to provide a waterproof function.

The connector body 10 includes an insulating seat 11 and a metal shell 30 with a through hole 31 . A tongue 12 extends outward from the insulating base 11 . The plurality of conductive terminals 20 are disposed on the tongue plate 12 at intervals. The metal shell 30 covers the insulating base 11 , and the metal shell 30 and the insulating base 11 form an insertion space 100 .

The waterproof case 40 includes an outer waterproof ring 41 surrounding the metal casing 30 and an inner waterproof ring 42 connected to the outer waterproof ring 41 . The inner waterproof ring 42 is extended from the outer waterproof ring 41 through the through hole 31 , one side of the inner waterproof ring 42 touches the insulating seat 11 , and the other side faces the insertion space 100 .
