Description

Terminal block separating structure {an terminal block separating structure}

The present invention relates to a terminal block detachable structure that allows the terminal block to be easily detached from the slide rail, and more specifically, a pair of locking protrusions provided on the terminal block through the push button to both sides to improve the separation of the terminal block easily. It is about.

In general, a terminal block for electrically connecting a plurality of wires may be fixedly installed on a fixed panel, but there are many examples in which the conveyance is freely installed in the longitudinal direction on the slide rail. It is related to the removable structure.

Conventionally, the terminal block detachable structure is mainly used in which the elastic latching protrusions are integrally provided on both sides of the lower part of the terminal block case. However, in the conventional structure, it is difficult to separate the terminal block from the slide rail once the terminal block is coupled to the slide rail. There was a problem that became very difficult.

In other words, when replacing a damaged terminal block with a new one during use or changing the position of the terminal block in the slide rail, it is necessary to separate the terminal block from the slide rail once. In this case, a separate tool such as a screwdriver must be used to forcibly separate the elastic catching protrusion of the slide rail in a narrow space, so that the separating work becomes very cumbersome and the elastic catching protrusion may be damaged during the separating process. there was.

Accordingly, the elastic catching protrusions are integrally provided on both lower sides of the terminal block case, and the handles for expanding the elastic catching protrusions on both sides of the terminal block case are integrally formed, or the catching members provided with the catching protrusions on both lower sides of the terminal block case are provided with springs. A terminal block attaching and detaching structure, such as a form in which elastic support is installed and a rotation cam is installed between both engaging members, has been proposed.

In the former terminal block detachable structures, in the former case, when the elastic catching protrusion is expanded through the handle, the terminal block can be easily separated from the slide rail. In the latter case, when the rotating cam is rotated using a tool such as a screwdriver, the spring is elastic. It is possible to separate the terminal block from the slide rail by moving both the supporting members and the locking projections to the outside, but in the former case, since the handle protrudes to the outside of the terminal block case, the overall volume of the terminal block is increased and the handle and the elastic locking protrusion There was a problem that the connection part is likely to be broken, and in the latter case, there are a lot of necessary parts, which is cumbersome to manufacture, and it is inconvenient to use a separate separation tool such as a driver to separate the terminal block.

The present invention has been devised in view of the deficiencies of the conventional terminal block attaching and detaching structures, and its purpose is to easily separate the terminal block from the slide rail without a separate separating tool, as well as easily and inexpensively with a small number of parts. It is to provide the detachable structure of the terminal block which can be manufactured.
