JP 2009-200017 A

  In order to connect the compression terminal and the device side terminal via the terminal adapter, it is necessary to use a terminal adapter suitable for the compression terminal and the device side terminal. For this reason, when the wire-side compression terminal or the device-side terminal is changed due to wire replacement or device replacement, the terminal adapter that has been used conventionally cannot be used, and a new terminal adapter needs to be prepared. For this reason, it is necessary to prepare in advance a plurality of types of terminal adapters corresponding to the shape and size of the electric wire side compression terminal or the equipment side terminal so that they can cope with an accident at a power station or the like.

  Further, in the conventional terminal adapter, when the electric wire side compression terminal and / or the device side terminal are changed, the terminal adapter used until then is wasted. Furthermore, in order to select a terminal adapter corresponding to a new wire side compression terminal and / or equipment side terminal, it is necessary to confirm the shape and dimensions of the wire side compression terminal and / or equipment side terminal, which takes time. In some cases, there was a problem that a power outage was required.

  The objective of this invention is providing the terminal adapter which can connect a some compression terminal and an apparatus side terminal.

  The present invention relates to a terminal adapter for connecting a compression terminal connected to an electric wire and a device side terminal, the compression terminal mounting hole corresponding to the compression terminal mounting hole and the device side terminal mounting hole, and the device side terminal It consists of a pair of elongated plate-like terminal adapter pieces with mounting holes, and the distance between the compression terminal mounting holes and the device side terminal mounting holes can be changed by changing the arrangement of the pair of terminal adapter pieces. This is a terminal adapter.

  Further, in the terminal adapter of the present invention, at least one of the compression terminal mounting hole and the device side terminal mounting hole drilled in the terminal adapter piece is a position shifted from the center when viewed from the short direction of the terminal adapter piece. It is characterized by being perforated.

  Further, in the terminal adapter of the present invention, the arrangement of the pair of terminal adapter pieces includes an arrangement in which the front surface of one terminal adapter piece and the back surface of the other terminal adapter piece are combined. It is characterized by enabling connection corresponding to a combination of species.

  Further, the terminal adapter of the present invention is a terminal adapter that connects the compression terminal connected to the electric wire and the device side terminal at an angle, and one terminal adapter piece A is a central portion as viewed from the longitudinal direction, Compression terminal mounting holes or equipment side terminal mounting holes are drilled at three locations on both sides, both sides are bent at a predetermined angle, and the other terminal adapter piece B starts from the longitudinal center. The half is bent at the same angle as the side portion of the terminal adapter piece A, and the terminal adapter piece A is longer than the terminal adapter piece B by one side portion.

  Since the terminal adapter of the present invention comprises a pair of terminal adapter pieces that can change the distance between the compression terminal mounting hole and the device side terminal mounting hole by changing the arrangement, the arrangement of the pair of terminal adapter pieces is changed. Only a plurality of compression terminals can be connected to the equipment side terminals. At this time, the compression terminal and the device-side terminal can be connected in a state having an attachment angle as well as a straight line.

  Since the terminal adapter 10 is used in a state where the longitudinal side surface 14 (15) of the terminal adapter piece 11 and the longitudinal side surface 24 (25) of the terminal adapter piece 21 are abutted, the width (short) of the terminal adapter piece 11 is reduced. The length in the hand direction is an important factor for determining the distance between the mounting holes 12 and 13 of the terminal adapter piece 11 and the mounting holes 22 and 23 of the terminal adapter piece 21. Here, when the side surface 14 (15) of the terminal adapter piece 11 and the side surface 24 (25) of the terminal adapter piece 21 are brought into contact with each other, the mounting holes 12 (13) and 22 (23) of the two terminal adapter pieces 11 and 21 are used.
