Waterproof two side-pluggable USB connector and manufacturing method thereof

Abstract

The invention discloses a waterproof two side-pluggable USB connector, which comprises a metal isolation middle plate, a first terminal group, a second terminal group, and a metal inner shell, wherein the first terminal group and the second terminal group are arranged at two sides of the metal isolation middle plate respectively; each of the first terminal group and the second terminal group comprises a touch part and a welding pin integrated with the contact part respectively; a first insulation body is integrated and formed on the first terminal group to form a first combination body; a second insulation body is integrated and formed on the second terminal group to form a second combination body; the metal isolation middle plate, the first combination body or the second combination body, and a third insulation body are integrated to form a third combination body; the third combination body, he first combination body or the second combination body and an insulated outer shell are integrated to form a fourth combination body; and the metal inner shell sleeves the fourth combination body and a waterproof adhesive is coated. The problem that the existing in-mold injection molding technology can not integrate complicated components as a whole and waterproof performance is poor can be effectively solved.

Description

technical field [0001] The present application relates to the field of electrical connectors, in particular to a waterproof USB connector and a manufacturing method thereof. Background technique [0002] The Universal Serial Bus (USB) widely exists in people's daily life, and most of the data transmission of electronic devices adopts this common standard; the emergence of the USB3.0 standard has greatly improved the data transmission speed. In terms of USB interface design, USB3.0 can perfectly implement design changes without affecting backward compatibility and structural appearance. However, in the MicroUSB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The MicroUSB3.0 standard eventually complicates the appearance structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. However, it takes up more space and...

Problems solved by technology

However, in the MicroUSB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The MicroUSB3.0 standard eventually complicates the appearance structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. However, it takes up more space and is limited to the development trend of ultra-thin smartphones, which greatly limits the application of MicroUSB3.0 on mobile phones. A new high-speed serial universal bus is urgently needed to solve this problem.

[0003] In this case, the USB Association has launched a new USB3.1 Type C interface connector, which takes into account both size and performance, and is suitable for applications on smart terminals, but it is not backward compatible

Due to the complexity of the product structure and the existence of the metal isolation mid...
