The purpose of the utility model is to provide a new data line connection terminal socket with a locking function when the data line plug is connected to the socket, so that the connection of the data line during transmission is very reliable and stable.

In order to achieve the above-mentioned technical purpose, the technical solution adopted by the utility model includes the following technical content: a USB socket with a locking function, which is composed of a combined terminal base provided with connecting terminals and a shell covering the outside of the combined terminal base, It is characterized in that: the combined terminal base is composed of a main terminal base and a secondary terminal base that are plugged together, a square ring terminal socket is arranged in the middle of the main terminal base, and the middle part of the socket is a columnar terminal connection. A connecting terminal is fixed on the outer wall of the connecting head, and at least one locking hole is provided on the outer wall of the terminal socket. Connecting terminals are fixed on the outer wall, and the main terminal base and the auxiliary terminal base are integrated into a whole through the mutually matched chucks and bayonet fixing buckles.

The outer side of the main terminal base is provided with a groove-shaped positioning block installation groove, in which a positioning block is arranged, and the positioning block is provided with terminal positioning holes having the same number as all connecting terminals on the main terminal base and the auxiliary terminal base.

The middle parts of all the connecting terminals arranged on the main terminal base and the auxiliary terminal base are bent in the same direction, and the bent tails of the terminals are inserted into the corresponding positioning holes in the positioning block.

In order to adopt the above-mentioned technical solution, the utility model has obtained the following technical advantages and effects: the utility model adopts the structure of setting a positioning hole on the inner side of the socket on the main terminal base, so that the plug with the locking hook can use the above-mentioned The positioning hole is used for locking, and this structure effectively improves the connection strength between the terminal plug and the socket, avoiding the problem of data transmission failure caused by poor contact; by adopting the combined structure of the terminal block, the mold is greatly reduced. Production cost, to achieve the purpose of reducing production cost and production difficulty; by setting the positioning block, the fixing strength of the connecting terminal is very effectively improved, and at the same time it is convenient for the welding between the next step and the data line, because the positioning hole can effectively define The position of the connection terminal tail is convenient for use with automatic soldering.

In a word, the utility model provides a new connection terminal socket with reliable connection, stable signal and low production cost through the above series of structural improvements.
