Electric connector

Abstract

An electric connector is used for being electrically connected with a circuit board and comprises: a terminal module, wherein the terminal module comprises an insulating body and a plurality of conductive terminals fixed on the insulating body, wherein the insulating body comprises a base and a tongue plate extending forwards from the base; a metal shell which is arranged on the periphery of the terminal module in a surrounding mode, wherein the metal shell and the base jointly form a containing cavity with a forward opening, the tongue plate is in a cantilever shape forwards and is at least partially located in the containing cavity, and a clamping groove with a forward opening is formed in the position, located on the periphery of the opening of the containing cavity, of the metal shell;and a waterproof ring which is arranged on the periphery of the opening position, located in the containing cavity, of the metal shell in a sleeving mode, wherein at least part of the waterproof ringis clamped in the clamping groove. Good waterproof performance is realized.

Description

【Technical field】 [0001] This application relates to an electrical connector. 【Background technique】 [0002] The Universal Serial Bus (USB) widely exists in people's daily life, and most electronic equipment data transmission adopts this common standard; the emergence of the USB3.0 standard has greatly improved the data transmission speed, in the standard A Type In terms of USB interface design, USB3.0 can perfectly implement design changes without affecting backward compatibility and structural appearance. However, in the Micro USB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The Micro USB 3.0 standard eventually complicates the appearance and structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. , but takes up more space, limited to the development trend of ultra-thin smartphones, the application of M...

Problems solved by technology

The usual waterproof solutions include silicone rings, integrated silicone molding, and glue dispensing. However, with silicone rings, the silicone rings tend to slip and deviate, resulting in a decline in waterproof performance; while the cost of silicone integrated molding is too high and the yield rate is too low; The dispensing scheme is more and more beginning to be applied; as the patent application of the People's Republic of China Publication No. CN109217012A discloses a kind of dispensing scheme, adopts the powder metallurgy process to manufacture the shielding shell, and the glue tank is set at the front edge of the shielding shell, but this kind Powder metallurgy or CNC processing schemes to manufacture shielding shells still have high manufacturing costs and low customer acceptance; while the People's Republic of China Publication No. CN109449634A patent discloses a USB socket, the front edge of the inner metal shielding shell Integral molding has an upward flanging, and the flanging can be enclosed with the front edge of the outer metal shielding shell to form a groove. The existing glue dispensing method is to dispense glue in the groove, but the groove is relatively small. Shallow, the glue is easy to overflow after dispensing, causing bad
