Description

Technical Field

[0001] The utility model belongs to the technical field of wall sockets, and particularly relates to a modular surface-mounted single-gang audio socket with a built-in module insert structure that is compatible with installation and use on 86-type and 120-type back boxes. Background Art

[0002] At present, ordinary national standard 86-type back boxes are generally installed in domestic building walls. When installing a US standard socket on an 86-type back box, an external module that can be installed on the 86-type back box needs to be designed to solve the problem of installing a US standard socket. For high-power electrical appliances with special requirements, if conditions permit, a US standard socket can be installed on the 86-type back box for use, or a 120-type back box can be directly installed in the wall during interior decoration, and at the same time, a power cord with a larger square specification needs to be replaced to meet the connection and use of high-power electrical appliances with special requirements for power supply.

[0003] However, for high-power electrical appliances with special requirements for power sockets, there are many power cords with larger square specifications available in the market. However, special power sockets with very thick insert copper sheets that can meet certain power requirements on the wall are very rare.

[0004] To solve the power connection problem of high-power power amplifiers, ensuring stable voltage and current at the power connection terminal is the basis for ensuring the good operation of audio equipment. Since the power amplifier requires a larger current and more abundant power reserve, for high-power power amplifiers that pursue extreme effects, using a single-gang insert wall socket is particularly important; because the single-gang socket is not affected by the outside world and is more pure, and at the same time, it avoids electromagnetic interference between the double-gang inserts, and also highlights the role and advantages of the single-gang socket in preventing crosstalk.

[0005] Therefore, for the problem of wall socket adapter installation of a US standard socket on a national standard 86-type back box and the installation of a single-gang socket on a US standard 120-type back box, we urgently need to innovatively design a modular surface-mounted single-gang audio socket with a built-in module insert structure that is compatible with installation and use on 86-type and 120-type back boxes. Content of the Utility Model

[0006] To solve the problem of installing and using a US standard single-gang socket on an 86-type or 120-type back box in the wall, and in the case where there is no space for installing a US standard insert, this patent particularly innovatively designs a modular surface-mounted single-gang audio socket with a built-in module insert structure that is compatible with installation and use on 86-type and 120-type back boxes.

[0007] To achieve the above object, the concept of the utility model is:

The built-in space of the ferrule structure and the fixing holes for the wire-locking screws equipped on the ferrule are specially processed on the ferrule module; among them, a split ferrule made of independent copper is specially designed. The split ferrule is composed of an independent live wire connection block, a neutral wire connection block, and a ground wire connection block. The split ferrule is built into the ferrule module made according to the tolerance fit, and is restricted to be installed on the back of the ferrule module by a specially designed limit back plate, forming a ferrule module assembled with independent live wire, neutral wire, and ground wire connection blocks. A single-pole panel made of aluminum alloy material is installed on the front of the ferrule module; finally, a shielding outer box made of aluminum alloy material is designed, and the ferrule module assembled with the split ferrule is assembled together to form a complete modular surface-mounted single-pole audio socket.
