Problems solved by technology
[0004] The installation and locking structure of the existing waterproof electrical connector not only affects the assembly efficiency of the product, but also brings great hidden dangers to the reliability of the product. For example, when the thread is locked tightly, it may be caused by eccentricity during processing of the embedded nut. It is not strong enough and the insert nut breaks when the mounting screw is tightened
When the press fit is fixed, the inner nut may come out due to insufficient interference between the inner nut and the support sleeve
In addition, since these fixing methods all adopt the form of back-end fixing, it cannot cooperate with the late glue filling in the process, resulting in difficulty in forming waterproof glue, low production efficiency, and poor waterproof performance

The invention discloses a water-proof electric connector with an embedded nut fixed by an overturned riveting structure. The electric connector comprises a connector, the embedded nut and a sealing plate, and is characterized in that the embedded nut is provided with a speaker hole-shaped riveting mouth at one end; a water-proof sealing ring is arranged on the sealing plate; the embedded nut is sleeved in the sealing plate and the through hole of the connector so as to fixedly connect the connector and the sealing plate in a way of pressing and riveting the overturned edges of the riveting mouth; and water-proof glue is adopted to seal the embedded nut and the tail end of the connector. Compared with the prior art, the electric connector has the advantages of simple structure, good water-proof performance, high reliability, convenience in the realization of automatic installation and automatic glue filling. The water-proof glue can be formed once depending on its flowability. Due to the adoption of the connector, the assembly efficiency is improved, and the part manufacturing cost is further reduced.
Description
Technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a waterproof electrical connector for fixing an embedded nut with a flip riveting structure. Background technique [0002] In today's electronic communication field, the application of electrical connectors is more and more extensive, and there are many types. In the process of using electrical connectors, in order to meet the use of special environments, it is often necessary for electrical connectors to have good waterproof performance to ensure the equipment For internal electrical performance and connection reliability, waterproof electrical connectors are one of them. [0003] At present, the installation and locking structure of waterproof electrical connectors adopts the inlay nut fixed on the connector to be locked and fixed on the mounting plate through the installation screw, and the fixing method of the inlay nut and the connector is usually screwed and fixed. ...
