Description

  The present invention relates to a terminal adapter used when connecting a compression terminal connected to an electric wire and a device-side terminal.

  The compression terminal is used for connection between the electric wire and the device. When connecting an electric wire and an apparatus using a compression terminal, connect the compression terminal to the electric wire side, and connect this compression terminal to the apparatus side terminal. At this time, the compression terminal and the device-side terminal may be connected via a terminal adapter.

And the terminal adapter 221 are overlapped, and a bolt is inserted into the mounting hole and fixed with a nut. The connection between the device side terminal 211 and the terminal adapter 221 is performed in the same manner. By interposing the terminal adapter 221, even if the pitch (dimension) and the number of the mounting holes 204 of the compression terminal 201 and the mounting holes 214 of the device side terminal 211 are different, the compression terminal 201 and the device side terminal 211 can be easily connected. Can be connected.

  If the pitch and the number of the mounting holes 204 of the compression terminal 201 and the mounting holes 214 of the device side terminal 211 are the same, the compression terminal 201 and the device side terminal 211 can be overlapped and directly connected, Even in such a case, the connection may be made via the terminal adapter 221.

  Many terminal adapters connect the compression terminal and the device side terminal linearly as shown in Fig. 9, but also developed a terminal adapter (connection adapter) to change the mounting angle between the compression terminal and the device side terminal. (For example, refer to Patent Document 1).

  Further, in the terminal adapter of the present invention, when the two types of compression terminals and device side terminals having different mounting hole pitches and hole diameters have a total of six mounting holes of 3 × 2 rows, The mounting holes are arranged so that the mounting angles of the compression terminals with respect to the device-side terminals can be connected at three angles on the same plane, and the number of the terminal mounting holes required when the terminal mounting holes are not shared. The number of the terminal mounting holes is reduced to 17 by providing the common circular hole and the common deformed elongated hole.

  In the terminal adapter according to the present invention, the terminal adapter is bent at an arbitrary angle at a boundary between an attachment surface of the compression terminal and an attachment surface of the device-side terminal.

  Moreover, the terminal adapter of this invention WHEREIN: The display which shows the connection location according to the kind of the said compression terminal and the said apparatus side terminal corresponding to the said terminal adapter is given.

  The terminal adapter 80 of the fourth embodiment and the terminal adapter 50 of the third embodiment have the same technical idea and method of use. However, the terminal adapter 80 of the fourth embodiment is similar to the terminal adapter 50 of the third embodiment. The shape is bent by 90 °. In the terminal adapter 50 of the third embodiment, the compression terminal 205 (201) and the device side terminal 215 (211) are connected on the same plane, but the terminal adapter 80 of the fourth embodiment has a compression terminal. The compression terminal 205 (201) and the device side terminal 215 (211) are connected in a state in which the mounting surface 91 is at an angle of 90 ° with respect to the device side terminal mounting surface 92.

  The terminal adapter 80 is bent at 90 ° in the vicinity of the boundary between the compressed terminal mounting surface 91 provided with the compressed terminal mounting hole 52 and the device side terminal mounting surface 92 provided with the device side terminal mounting hole 13. It has an inverted L shape in side view.

  The method of connecting the compression terminal 205 (201) and the device side terminal 215 (211) to the terminal adapter 80 is the same as that of the terminal adapter 50 of the third embodiment.

  In the terminal adapter 80 of the fourth embodiment, the bending angle is 90 °, but the bending angle is not limited to 90 °, and may be an arbitrary angle. If the terminal adapter 80 of 4th Embodiment is used, the compression terminal 205 (201) and the apparatus side terminal 215 (211) can be connected in the state in which the compression terminal attachment surface 91 and the apparatus side terminal attachment surface 92 had an angle. is there.

  As shown in the first to fourth embodiments, in the terminal adapter of the present invention, the terminal mounting hole includes two or more types of compression terminals and device side terminals having different mounting hole pitches and / or hole diameters. Alternatively, since at least one of the terminal mounting holes is a common circular hole or a common deformed elongated hole that can be shared between different types of compression terminals or device side terminals, With a terminal adapter, multiple types of compression terminals and equipment-side terminals can be connected without rattling and can be made compact.

  Further, even when the compression terminal and the device side terminal are connected at an angle as in the terminal adapter 40 of the second embodiment, the compression terminal and the device side terminal having different dimensions can be connected. Moreover, since the angle which connects a compression terminal and an apparatus side terminal can be set to arbitrary angles, it is convenient.

  Even when the terminal is connected with an angle between the mounting surface of the compression terminal and the mounting surface of the device side terminal as in the terminal adapter 80 of the fourth embodiment, the different types of compression terminal and device side terminal are connected. Connection with is possible. In addition, the angle between the mounting surface of the compression terminal and the mounting surface of the device side terminal can be set to an arbitrary angle, which is convenient.

  In the terminal adapter of the present invention, it is possible to easily connect the compression terminal and the device-side terminal by providing a display corresponding to the connection location of the compression terminal and the device-side terminal on the terminal adapter. The display for indicating the connection location is not limited to the marking, and a seal, ink, or the like may be used. It is preferable to provide a display indicating the direction of connection.

  In addition, the terminal adapter of this invention is not limited to the said embodiment, It can change and use in the range which does not change a summary. For example, the terminal adapter 10 of the first embodiment may be bent and used like the terminal adapter 80 of the fourth embodiment. Further, the terminal connection angle of the terminal adapter 50 of the third embodiment is not limited to 0 °, 45 °, and 90 °, and the arrangement of the attachment holes 52 may be changed so as to be any three kinds of angles. Moreover, the attachment direction with respect to the ground (illustration omitted) of an apparatus side terminal is not limited to a specific direction in this invention.
