Hardening type high-stability case USB interface

Abstract

The invention discloses a hardening type high-stability case USB interface, and belongs to the field of USB interfaces. The hardening type high-stability case USB interface can form a buffer gradient between the USB interface and the inner wall of a case shell through the arrangement of a plurality of self-hardening glue overflow hemispheres, so that the USB interface is not liable to fall off from the case shell in multiple plugging operations of a plug, meanwhile, when the self-hardening glue overflow hemispheres are subjected to large pulling force, the self-hardening glue overflow hemispheres are instantly stressed and greatly deforms, so that a jacking ball pushes a self-hardening bag to quickly approach the conical angle, the self-hardening bag expands outwards in the longitudinal direction, quick-drying glue is extruded from the inside, the self-hardening glue-overflow hemispheres are broken, the quick-drying glue overflows, a bonding effect is formed, and it is effectively guaranteed that the interface can still keep high stability after accidental pulling force; moreover, the conical angle punctures a top point ball, the self-hardening bag is hardened to form a supporting effect in the self-hardening glue overflow hemispheres, the situation that the self-hardening glue overflow hemispheres are extremely prone to deformation due to low elasticity and stress after the quick-drying glue overflows is effectively relieved, and the stability is further improved.

Description

technical field [0001] The invention relates to the field of USB interfaces, and more specifically relates to a hardened USB interface of a chassis with high stability. Background technique [0002] USB is an external bus standard that regulates the connection and communication between computers and external devices. The USB interface has a hot-swap function. The USB interface can connect a variety of peripherals, such as mouse and keyboard. USB was jointly launched by Intel and other companies in 1996 at the end of 1994. It has successfully replaced serial ports and parallel ports, and has become a must-have interface for computers and a large number of smart devices today. The USB version has undergone years of development and has now grown to version 3.1. For most engineers, the main obstacles in the development of USB2.0 interface products are: to face the complicated USB2.0 protocol, write the driver program of USB device by themselves, and be familiar with the progr...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a hardened high-stability chassis USB interface, which can be formed between the USB interface and the inner wall of the chassis shell through the setting of a plurality of self-hardening hemispheres. The buffer gradient makes it difficult for the plug to fall off from the chassis during multiple plugging and unplugging operations. At the same time, when it is subjected to a large pulling force, the self-hardening overflow rubber hemisphere is instantly deformed by a large force, so that the apex ball pushes the self-hardening capsule and quickly Close to the taper angle, on the one hand, the self-hardening capsule expands longitudinally outward, and the quick-drying glue is squeezed from the inside, so that the hemisphere of the self-hardening overflowing glue is broken, and the quick-drying glue overflows, forming a bonding effect, which effectively guarantees the interface after accidental pulling force It can still maintain high stability. On the other hand, the cone angle pierces the apex ball, and the self-setting capsule hardens to form a supporting effect in the self-setting overflow hemisphere, which effectively relieves the elasticity of the self-setting overflow hemisphere due to the overflow of the quick-drying adhesive. The case of low force and easy deformation further improves stability
