A combinable wiring board

Abstract

The invention relates to the field of combinable wiring board products, in particular to a combinable wiring board, which has a hollow structure of the wiring board body, and is provided with live wire and neutral wire electrical connectors in the hollow structure of the wiring board body, and the wiring board body There are also connection plugs and connection sockets; the connection sockets and the sockets to be connected are all provided with the connection plugs or the locking parts of the connection plugs corresponding to the other wiring board body for locking respectively. The locking part of the combined terminal board is a sliding lock. The sliding lock of the combined terminal board is provided with a chute. column; the present invention can be freely expanded according to the needs of users, and the connection structure is reliable.

Description

technical field [0001] The invention relates to the field of power supply device products, in particular to a power conversion device that can be freely combined as required. Background technique [0002] In order to make the power terminal board freely expandable according to the user's needs and meet the user's expansion needs, at the same time, when the user's demand for power sockets decreases, it can freely reduce the number of combinable terminal boards to reduce storage space. There are many power terminal boards that can be disassembled and combined according to user needs on the market. [0003] For example, the authorized announcement number is CN201508951U, and the title of the invention is: a Chinese utility model of a connection type socket, which discloses a connection type socket, including a female socket and a sub-socket connected with the female socket, the female socket and the sub-socket Each includes one or more parallel electrode units, and at least on...

[0004]However, the reliability of the connection mechanism between the female socket and the sub-socket in the connection type socket of this structure is poor. When the connection between the female socket and the sub-socket When the mechanism is subjected to a force in the normal direction, it is easy to make the female socket and the sub-socket loose

[0005]In addition, because the socket of the above-mentioned structure adopts the plug-in piece inside the socket is only a sheet, which is dug and folded on the sheet, so the plug-in piece and the plug The contact surface of the socket is not as big as the contact surface of the electrical connector and the plug of the ordinary plug-in strip (they are all in the form of linear contact with the pin surface), and the digging and folding method on the chip is a closed space, which cannot be released when the plug is pulled out. The internal stress tension that needs to be released, so the pull-out force of the plug on the socket is still not good. Long-term pull-out will cause metal fatigue, resulting in loose pull-out, resulting in unstable contact between the plug and the electrical connector
