Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a terminal device in which the number of poles can be changed by connecting a plurality of one-pole terminal units as necessary.

[Prior Art] Conventionally, in the case of a terminal device that is mounted on a printed circuit board to connect external lines, a terminal device has been known in which a one-pole terminal unit having a single wiring connection portion and one or more lead pins to be attached to the printed circuit board is prepared, and this terminal unit is connected to the terminal device in the number of poles required.

In the case of a terminal device such as this, in which terminal units are made into blocks in units of one pole and used by connecting the required number of terminal units, there is no unused pole unlike in a normal terminal device, and the required minimum number of terminals can be installed on the printed circuit board. Since it is only necessary to secure the space, it can greatly contribute to saving the installation space.

[Problem to be solved by the invention] However, in the case of a terminal device in which conventional terminal units are connected for the required number of poles, the length of the terminal device also changes as the number of poles changes.
Therefore, in order to affix the terminal card, the length of the terminal card affixing stand provided in the terminal device must also be changed.

Therefore, prepare multiple types of terminal card adhesion stands for each length of the terminal device according to the number of pins expected to be used, and select a terminal card adhesion stand with a length commensurate with the number of units to be used. Therefore, there was a problem in that the terminal card attachment stand could not take full advantage of the advantages of a terminal device in which the number of poles can be changed.

The present invention was developed in view of these conventional problems, and provides a terminal device in which the length of the terminal card affixing stand can be easily changed according to the change in length due to the number of terminal units. The purpose is to

[Means for Solving the Problems] First, the present invention allows the number of poles to be changed by connecting a plurality of one-pole terminal units each having a connection portion for at least one pair of input/output lines as necessary. In addition, the target is a terminal device equipped with a terminal card pasting stand.

Regarding such a terminal device, in the present invention,
When a plurality of the terminal units are connected, a bearing part is formed on both sides of the connected terminal units so that the terminal card pasting stand is rotatably mounted between a horizontal position and a vertical position with respect to the terminal device. Further, the terminal card pasting stand has a plate part for pasting the terminal card and a hinge part for supporting the plate part, and the plate part and the hinge part have a length per terminal unit of one pole. A terminal card pasting stand is provided which is adapted to the number of connected terminal units by forming a separation groove that can be separated at a pitch, and which is located at a length position corresponding to the number of poles determined by the number of connected terminal units. The hinge portions on both sides of the terminal card sticking stand are mounted on bearing portions of support members provided on both sides of the terminal unit.

[Function] With the terminal device of the present invention having such a configuration, even if the length of the terminal device changes due to the connection of a plurality of terminal units according to the number of poles, the terminal card attachment base does not contain any terminals. Since the separation grooves are pre-formed at the length pitch of the unit, the required length can be obtained by separating the terminal card pasting base by hand or with a cutter at the separation groove part corresponding to the number of connected terminals, and the terminal unit can be cut to the desired length. The advantage of a terminal device in which the number of poles can be changed depending on the number of connections can be effectively utilized.

Furthermore, since the terminal card attachment stand is attached to the bearing part of the support member so that it can rotate freely between horizontal and vertical positions with respect to the terminal device, it The terminal card attachment base can be rotated to the required position in any horizontal position.
