DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a distribution board having a cutout mechanism installed at a connection point between an external line and premises equipment, for example.

[Conventional technology]

For example, a local telephone line and an external telephone line are connected via a distribution board. In this type of distribution board, the cables that are external lines and the cables from the premises equipment are connected in advance to the terminal board, which is one component of the distribution board, and the terminal board to which the external cable is connected is connected to the premises equipment. It has a configuration in which it is connected to the Jeanno busbar in accordance with the terminal board, and a protector is installed between the external cable and the internal cable to protect against accidents caused by overvoltage or overcurrent. is used. In addition, the wiring board consisting of these terminal boards and protectors,
It consists of many pieces depending on the telephone line.

[Problem that the invention seeks to solve]

As mentioned above, conventional wiring boards are made up of a variety of components, and each of these components requires terminals of various shapes for connection to other components. S-)

The present invention was proposed to solve the above-mentioned conventional problems, and aims to standardize and unify the components of a distribution board, thereby reducing the number of parts and simplifying construction, handling, and maintenance and inspection. The purpose of the present invention is to provide a wiring board that can realize high-density wiring boards with the standardization of component parts and make effective use of space.

[Failure to solve the problem]

The distribution board according to the present invention includes a plurality of electrical connector blocks that are insulated from each other and are arranged in parallel and each has quick connect terminals and terminals at both ends, and a bridge section that bridges the electrical connector blocks to each other. The present invention is characterized in that it is equipped with a jack device having a mechanism for attaching an insertion plug and a protector to each bridge portion in a removable manner.

[Effect]

In accordance with the present invention, at least two electrical connector blocks are provided having a plurality of electrical connectors disposed along two opposite ends, the electrical connector blocks are arranged in parallel, and the electrical connector blocks are arranged in parallel. The bridge parts that bridge each other are equipped with a disconnection mechanism that allows for removable installation of push-in bladders such as disconnection bladders, various test plugs, and protectors that respond to overvoltages and overcurrents. As a result, the basic configuration of the electrical connector block can be made with one type of the same shape, and everything is the same as before by simply attaching the protector to the electrical connector block via the jack device and jack device. It can have a security function.

Further, since the two opposite ends of the electrical connector block have the same shape, the wiring connection can be arbitrarily selected, and the connection direction of the jacking device to the electrical connector block can also be arbitrarily selected accordingly.

Furthermore, the contact section of the jack device, which is installed bridging the electrical connector block, allows the mechanism to be operated or installed from two directions, so for example, one side can be used with a
It is also possible to insert a cutting plug from the other side when cutting.

Furthermore, since a grounding plate can be attached to the jack device, if the safety device is to be grounded, the safety device can be grounded by attaching this grounding plate, and the safety device can be easily grounded (earthed). It is designed to solve the above-mentioned problems of the conventional method.
