Reference numeral 00 denotes a configuration in which a plurality of terminal blocks 106 in which a plurality of terminals 104 are fixed vertically on a terminal base 102 are stacked. In a terminal plate in which an extremely large number of terminals are arranged in this way, when connecting to an arbitrary part of the terminal group, the conventional crocodile clip has to correspond one-to-one to each terminal, so that labor is large. Also, workability such as incorrect wiring was poor.

[0004] Further, since the terminals are close to each other at a short distance, the operation space for the connection operation by the alligator lip is extremely narrow, the connection is troublesome, and the operation efficiency is extremely low.

[0005] Further, since the connection strength relies only on the holding pressure of the spring, the worker may be hooked and disconnected after connection, or easily disconnected due to external factors such as vibration, resulting in electrical disconnection. , The reliability in connection work was low.

Accordingly, the applicant has filed a separate application (named the same as the present application) on the same date, while holding a connector main body mounted on a terminal plate and a connection terminal facing a part of a terminal group of the terminal plate. The connector body is provided so as to be movable in the facing direction of the terminal and the connection terminal, and A connector provided with a connection terminal base capable of displacing the connection terminal in a direction substantially perpendicular to the facing direction has been proposed. According to this, the terminal to be connected and the corresponding connection terminal can be mechanically connected collectively by moving the connection terminal base to a predetermined connection position after mounting the connector body on the terminal plate. It is possible to improve the work efficiency and the reliability of the connection. When changing the connection target site, the connection terminal can be displaced to a target terminal position by moving the connection terminal in a non-connection position in a direction substantially perpendicular to the connection direction.

However, according to the above connector,
Due to the connection to a part of the terminal group, there is a concern that it is difficult to obtain a sufficient connection strength between the terminal and the connection terminal due to a weak attachment strength of the connector main body to the terminal plate due to only the attachment.

Accordingly, an object of the present invention is to provide a terminal plate connector which can obtain a sufficient connection strength by a simple operation even when a part of the terminal group is connected.

[0009]

In order to achieve the above object, the present invention provides a connector main body mounted on a terminal board provided with a plurality of terminals and a part of the terminal of the terminal board. The connection terminal is held to face the terminal and is movably provided on the connector body along the direction in which the terminal and the connection terminal face each other, and the terminal is connected to the connection terminal by moving to the terminal side. Connection terminal base to be
And a pressing and holding member that presses and holds the terminal plate to the connector body in conjunction with the movement of the connection terminal base toward the terminal.

[0010]

According to the present invention, after the connector main body is mounted on the terminal plate, the connection terminal base is moved toward the terminal to be connected, and is positioned at a predetermined connection position. As a result, the connection target terminals in the terminal group and the corresponding connection terminals are collectively connected. Further, the terminal plate and the connector body are pressed and held by the pressing and holding member in conjunction with the movement of the connection terminal base, whereby the mounting strength of the connector body to the terminal plate is obtained, and the connection strength of the connection terminal to the terminal is reinforced. You. When changing the connection target portion, the connection terminal is moved substantially perpendicular to the connection direction in the non-connection position and is displaced to the target terminal position.
