A front rubber core structure for usb connector

Abstract

The invention discloses a front rubber core structure used for a USB (universal serial bus) connector. The front rubber core structure comprises front rubber core main bodies and grounding elastic piece plates fixedly arranged on the front rubber core main bodies, wherein a plurality of ribs are uniformly arranged on an inner side of each front rubber core main body, accommodating grooves are formed between adjacent ribs, multiple elastic piece through grooves are formed in one side of the accommodating groove of each front rubber core main body, limiting grooves are formed on the other side of the accommodating grooves of each front rubber core main body and are located in an outer surface of the corresponding front rubber core main body, clamping grooves are symmetrically formed in two side walls of an end, where the limiting grooves are formed, of each front rubber core main body, and a positioning groove and a positioning column are arranged on two side walls of an end, where the elastic piece through grooves are formed, of each front rubber core main body respectively; each grounding elastic piece plate comprises a grounding elastic piece plate body and grounding elastic pieces fixed to the grounding elastic piece plate body, and the grounding elastic pieces are accommodated in the elastic piece through grooves. The front rubber core structure can effectively improve work efficiency and installation quality, male-female insertion is stable, and the front rubber core structure is convenient and practical.

Description

[0001] Technical field: [0002] The invention relates to the technical field of USB connectors, in particular to a front rubber core structure of the 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] There are multiple grounding shrapnels fixed in the front rubber core structure of the existing USB connector. When installing, one end of the grounding shrapnel needs to be fixedly arranged in the shrapnel through groove of the front rubber core body. Since there are multiple grounding shrapnels, it is necessary to It is necessary to repeat many times to install all the grounding shrapnels...

AI Technical Summary

Problems solved by technology

[0005] There are multiple grounding shrapnels fixed in the front rubber core structure of the existing USB connector. When installing, one end of the grounding shrapnel needs to be fixedly arranged in the shrapnel through groove of the front rubber core body. Since there are multiple grounding shrapnels, it is necessary to It is necessary to repeat many times to install all the grounding shrapnel. The installation process is complicated, time-consuming and labor-intensive, and after repeated installations, the workers are prone to fatigue, the installation quality cannot be guaranteed, and the grounding shrapnel is easy to loosen.
