USB (Universal Serial Bus) data line mobile telephone terminal interface protective sleeve

Abstract

The invention discloses a USB (Universal Serial Bus) data line mobile telephone terminal interface protective sleeve. A mobile telephone terminal interface of a USB data line (4) comprises an inserting part (4a) and a fixed holding part (4b); the protective sleeve comprises a cant column-shaped rubber sleeve body; the rubber sleeve body (1) is axially provided with a through hole (2) matched with the fixed holding part (4b); one rhombic face of the rubber sleeve body (1) is provided with an arc-shaped groove (3) matched with the side part of a mobile telephone (5); The rubber sleeve body is provided with the through hole which is used for sleeving the fixed holding part of the mobile telephone terminal interface of the USB data line; by virtue of the arc-shaped groove, the rubber sleeve body is matched with the side part of a mobile telephone, so that the USB data line mobile telephone terminal interface can be tightly connected and matched with the mobile telephone; on one hand, the rubber sleeve body is capable of preventing the relative movement between the USB data line mobile telephone terminal interface and the mobile telephone; on the other hand, the rubber sleeve body is capable of releasing and decomposing external collision by use of the self flexibility characteristic, so that the USB data line mobile telephone terminal interface is prevented from being damaged.

Description

technical field [0001] The invention relates to the field of mobile phone accessories, in particular to a USB data line mobile phone terminal interface protective case. Background technique [0002] As is well known, for current smartphones, tablet computers and other products, USB data lines are generally used for charging and data transmission, but when the mobile phone interface of the USB data line is plugged and unplugged with the mobile phone, it is often caused by improper plugging angle and force. Unequal reasons cause damage and loosening of the interface, and in the process of use, the interface is often loose and damaged due to vibration, which affects normal charging and data transmission; at this stage, only through the user when plugging and unplugging Note that the position of the USB data cable interface is level with the mobile phone, and be careful not to touch the interface when using it. This method depends entirely on the degree of caution of the user. T...
