Description

A USB interface magnetic transfer device

technical field

The invention relates to a USB interface magnetic transfer device, which is used to enhance the safety and usability of the existing USB interface. The device adopts the principle of magnetic adsorption to improve various defects of the traditional USB interface, and is suitable for all existing machines and peripherals using the USB interface.

Background technique

The existing USB interface adopts the plug-in connection principle, although it has the advantages of firm connection and low cost. However, there are also defects such as the interface is easily deformed and damaged, and it is easy to cause the device to fall off the ground when the USB peripheral cable is pulled and cause collateral damage. And the existing USB interface can only be inserted in a fixed direction when accessing, so that the user often inserts it repeatedly several times before successfully connecting, which is not convenient enough.

The design of the present invention aims to improve the above-mentioned various problems existing in the existing USB interface.

Contents of the invention

A USB interface magnetic transfer device, characterized in that: the magnetic transfer device includes: USB interface female seat (1), mobile terminal shell (2), mobile terminal magnet (3), mobile terminal contact (4) , USB interface male head (5), fixed-end housing (6), fixed-end magnet (7), fixed-end contact (8); wherein, the moving-end magnet (3), the fixed-end magnet (7) At work, they are attracted to each other to fix the mobile terminal housing (2) and the fixed terminal housing (6), and the mobile terminal contact (4) is connected to the fixed terminal contact (8) for transmission data.

This device achieves the following improvements by adding a set of magnetic transfer device between the male and female sockets of the traditional USB interface device.

First of all, the ease of use of the interface is increased. When in use, the mobile end of the adapter device and the fixed end of the adapter device only need to approach as required to realize automatic adsorption, and both positive and negative directions are available. It saves the user from looking for the socket, adjusting the pros and cons, etc. steps. Especially in a dark environment or in a small space, it increases the probability of a successful connection of the user to the device.

The device also increases the safety when the USB interface is connected. Once the device connected to the traditional USB interface is pulled by external force, the connection line of the device is easily damaged, and it may also pull the host device down or drop it to the ground. After the conversion device is added, the USB peripherals can be automatically separated when pulled by external force, which protects the connecting wires and prevents collateral damage.

Due to the design of magnetic adsorption and contacts, the life of the interface is longer than that of traditional USB interfaces that are mechanically plugged and unplugged during normal use. And once there is a problem with the connection part of the conversion device, it only needs to replace the conversion device, which greatly protects the built-in interface of the host and USB peripherals.

The mobile end of the device can be manufactured into USB direct plug-in type, side plug-in type, wire lead-out type and other structures to meet various needs of users. It prevents the situation that the USB device cannot be inserted and used due to the incompatibility of the insertion angle and the space.

detailed description

The magnetic conversion device is shown in Figure 1. The device includes: USB interface socket (1), mobile terminal housing (2), mobile terminal magnet (3), mobile terminal contact (4), USB interface male head (5), fixed terminal housing (6) , fixed end magnet (7), fixed end contact (8). The internal connection of the adapter device is physical, and the eight contacts at the fixed end and the four contacts at the mobile end are respectively connected to the traditional USB male and female heads according to the interface definition diagram shown in Figure 2. Now when the two parts are approached in the manner shown in Figure 3, the two parts will automatically combine to form the working state shown in Figure 4 because of the magnetic attraction. When turned horizontally by 180 degrees, the two parts of the contacts can still be normally connected in the order required for work. Promptly realized the dual-purpose function. When the mobile terminal is subjected to external force from the connected USB peripherals, if the external force is greater than the force of the magnetic attraction, the two parts can be separated automatically to prevent greater losses.
