No. 284812, "Title of Invention: Protector for Communication Equipment"
There is a structure disclosed in US Pat. This structure makes it easy to replace the protector by making it possible to insert and remove the protector in each element, greatly improving workability. This structure is designed to improve the current withstand capability and the transmission characteristics (capacitance to ground, etc.) of the circuit. As a specific structure, a line or a jumper wire connected to the line is accommodated in a line-side terminal, and an in-house terminal accommodates an in-house line to an in-house facility such as an exchange. A U-slit terminal is used as the terminal, and no soldering is required for the housing or removing operation.

[0003]

However, in this conventional apparatus, when connecting or disconnecting a connection line to or from a terminal board structure attached to a mounting rack, the line side terminal is placed on the front side and the station inside terminal is placed on the front side. Are disadvantageous in that, since they are arranged on the back side, it is necessary to arrange a relatively long connection conductor between the line side terminal and the station inside terminal, so that the structural size becomes large. It is necessary to perform the connection work from both the front and back sides of the board structure, and there is a disadvantage that the work efficiency is reduced. Further, since a U-slit terminal having a single U-slit on the OUT side is used as the U-slit terminal, in a state where the connection between the line-side connection line and the IN-side U-slit is secured. When the connection at the connection point between the connection line inside the office and the U-slit on the OUT side is changed, the interconnection path between the line side terminal and the office inside terminal is always "cut". Under such a condition that instantaneous interruption is not permitted, the connection cannot be changed while the line is in use.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and to carry out the operation of connecting and receiving or removing connection wires only from one side such as the front side of a terminal board structure. A U-slit terminal capable of executing the work of connecting and receiving or removing the connection line inside the station under conditions that do not allow instantaneous interruption of the line even during use of the line connected to the line side terminal. An object of the present invention is to provide a terminal board structure using a pair. Another object of the present invention is to provide a cascade connection circuit using a plurality of terminal board structures using the U-slit terminal pairs.

[0005]

In order to achieve this object, a terminal board structure using a U-slit terminal pair according to the present invention comprises a plurality of U-slit terminal pairs installed in a synthetic resin forming body having a quasi-cuboid shape. Terminal board having a structure described above, and configured to interconnect a plurality of input-side signal lines and a plurality of output-side signal lines using the corresponding U-slit terminal pairs in the plurality of U-slit terminal pairs, respectively.
