a usb connector

Abstract

The invention discloses a novel USB (universal serial bus) connector. The novel USB connector comprises a front rubber core module unit, a rear rubber core module unit, a casing and a shielding cover, wherein the front rubber core module unit comprises a pair of front rubber cores which are mutually buckled and grounding elastic piece plates fixedly arranged on the front rubber cores; one end of the rear rubber core module unit is inserted in the front rubber core module unit, the rear rubber core module unit comprises rear rubber cores, a connection part and terminals, the terminals are embedded in the rear rubber cores, the two ends of each terminal extend to the outside of the corresponding rear rubber core, the rear rubber cores are arranged on an upper end surface and a lower end surface of the connection part respectively, and the rear rubber cores are fixedly connected with the connection part into a whole; the front rubber core module unit is sleeved with the casing; the rear rubber cores of the rear rubber core module unit are sleeved with the shielding cover. The grounding elastic piece plates are firmly installed and easy and convenient to assemble, the work efficiency can be effectively improved, mutual male-female insertion is stable, and the novel USB connector has good plug-pull performance, long service life, convenience in assembly, convenience and practicability.

Description

[0001] Technical field: [0002] The invention relates to the technical field of USB connectors, in particular to a USB connector. [0003] Background technique: [0004] With the rapid development of computer hardware, peripheral devices are increasing day by day, and keyboards, mice, modems, and printers are generally connected to computers through USB connectors. The USB connector has the characteristics of fast transmission speed, support for hot plugging and connection of multiple devices, and has been widely used in various external devices. [0005] The existing USB connector has the following deficiencies: 1) There are multiple grounding shrapnels fixed in the front rubber core module unit. There are multiple grounding shrapnels, so it needs to be repeated many times to install all the grounding shrapnels. The installation process is complicated, time-consuming and labor-intensive, and after repeated installations, the workers are prone to fatigue, the installation qua...

Problems solved by technology

[0005] The existing USB connector has the following deficiencies: 1) There are multiple grounding shrapnels fixed in the front rubber core module unit. There are multiple grounding shrapnels, so it needs to be repeated many times to install all the grounding shrapnels. The installation process is complicated, time-consuming and laborious, and after repeated installations, the workers are prone to fatigue, the installation quality is not guaranteed, and the grounding shrapnels are easy to loosen. ;2) The structure of the connector has the disadvantage of short service life. After long-term use, the hook is easily deformed, resulting in poor contact, unreliable plugging and unplugging, which seriously affects the performance; 3) The rear rubber core module unit is separated and difficult to assemble. Large, low production efficiency, difficult to control quality and performance in the assembly process, low product qualification rate
