【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The members having the same basic functions as those of the conventional example are designated by the same reference numerals.

That is, the terminal device includes a terminal block 1 fixed to a substrate 19 (see FIG. 7), a terminal plate 2 to which a connection conductor (not shown) is connected, and a connection conductor pressed to the terminal plate 2. It consists of terminal screws 3 for fixing.

As shown in FIGS. 2 and 3, the terminal block 1 includes a terminal block body 4 to which the terminal plate 2 is fixed, and other terminal blocks formed on both sides of the terminal block body 4 (see FIG. 7). The upper surface is formed in a generally E-shape from the isolation wall 5 that isolates the. The terminal block body 4 has a through hole 6 extending in the vertical direction in FIG. 1 and an inner housing portion 7 in the vicinity of the through hole 6. The through hole 6 is formed in a rectangular shape in FIG. 3 when the terminal block 1 is viewed from above, and a conductor piece of the terminal board 2 described later penetrates through the through hole 6 to electrically connect the external board 19 and the connection conductor. Connect to. The inner housing portion 7 has a circular opening 7a substantially in the center of the terminal block body 4 in FIG. 3 and a rectangular opening 7b in the substantially center of the terminal block body 4 in FIG. 7b are formed so as to communicate with each other inside the terminal block 1 as shown in FIG. Further, in FIG. 3, reference numeral 8 is a press-fitting hole for press-fitting a fixed piece of the terminal board 2 described later.

The terminal plate 2 is made of a conductive metal, and has a screw hole 13 into which the terminal screw 3 is screwed, as shown in FIG. , A conductive piece 10 connected downward from the right end of the connection piece 9 and penetrating the through hole 6 to be connected to the substrate 19, a fixed piece 11 connected downward from the center of the connection piece 9, and a connection piece. The second connecting piece 12 is formed continuously from the left end of 9 and faces the conducting piece 10. The connecting piece 9 is provided with a screw hole 13 projecting downward in FIG. The fixed piece 11 has a saw-toothed concave-convex portion 14 for press-fitting into the press-fitting hole 8. The second connecting piece 12 is continuously provided below the connecting piece 9 in a substantially vertical direction, and has a screw hole 15 projecting toward the conducting piece 10 side. The screw hole 15 is fitted into the opening 7b of the terminal block 1. They meet.

The terminal screw 3 is formed of a screw portion 16 that is screwed into the screw holes 13 and 15 and a head portion 17 that press-connects and fixes the connecting conductor between the connecting piece 9. The screw part 16 is housed in the inner housing part 7 so that the tip of the screw part 16 does not contact the terminal block 1 when the terminal screw 3 is screwed on. The head 17 has a driver groove 18 for tightening with a driver. In addition, 20 in FIG. 7 is an inverter device.

To connect the connection conductor to this terminal device, when the connection conductor is inserted in a direction parallel to the substrate 19, the terminal screw 3 is removed from the screw hole 13 with a jig such as a screwdriver, and the connection conductor is connected. Insert the terminal block 1 from the direction A so as to connect to the connection piece 4, screw the terminal screw 3 into the screw hole 13, and tighten it with a jig such as a screwdriver to connect the connection conductor. When the connecting conductor is inserted into the substrate 19 in the vertical direction, the terminal screw 3 is removed from the screw hole 15 with a jig such as a driver, and the connecting conductor is transferred from the direction B of the terminal block 1 to the second connecting piece 12. It is inserted so as to be connected, the terminal screw 3 is screwed into the screw hole 15, and the connecting conductor is connected by tightening with a jig such as a driver.

According to this embodiment, since the terminal plate is fixed to the terminal block, the terminal plate is provided with the fixing piece, the terminal block is provided with the press-fitting hole, and the fixing piece is press-fitted into the press-fitting hole. Although the terminal plate is fixed to the terminal block by means of the above, any structure may be used as long as the terminal plate can be fixed to the terminal block such that the connecting piece is fitted and fixed to the terminal block. Further, the second connecting piece need not be opposed to the conducting piece as long as it is provided in a direction substantially perpendicular to the connecting piece.
