Problems solved by technology

[0006] However, in the terminal block unit of Patent Document 1, the three connection terminals corresponding to the respective phases of the 3-phase inverter and motor and the terminal portion of the bus bar are respectively fastened by bolt members. Therefore, when manufacturing the terminal block unit, It is necessary to repeat three times the work of fastening the terminal part connecting the terminal and the bus bar with a bolt member, resulting in a problem of poor productivity
In addition, it is necessary to arrange the fixed square nuts on the terminal board, so there is a problem that the manufacture of the terminal board is complicated.

[0077] First, refer to Figure 1 to Figure 2B The terminal board unit of the first embodiment of the present invention will be described.

[0078]

[0079] Such as figure 1 As shown, the terminal board unit 10 of this embodiment includes: a terminal board 20 having a substantially rectangular parallelepiped shape, which has an upper surface, a lower surface, a front surface, a rear surface, a left surface, and a right surface; and a pressing member 30 that is provided to cover The upper surface of the terminal board 20. On the upper surface of the terminal board 20, three mounting portions 21U, 21V, and 21W are formed side by side in the left-right direction. In this embodiment, the placement part is formed in the order of 21U, 21V, and 21W from left to right.

[0080] It should be noted that in this specification and the like, in order to make the description simple and clear, and for the sake of convenience, the surface of the terminal board 20 on which the mounting portions 21U...

[0103] Next, refer to Figure 3A to Figure 3E The terminal board unit 10A of the second embodiment of the present invention will be described. It should be noted that in the following description, the same components as those of the terminal board unit 10 of the first embodiment are assigned the same reference numerals to omit or simplify the description. The terminal board unit 10 of the first embodiment and the second The different points of the terminal board unit 10A of the embodiment will be described in detail.

[0104] Such as Figure 3A As shown, in the terminal board unit 10A, the left end of the upper surface of the terminal board 20 and the left end of the pressing member 30 are connected by the rotating portion 70. The pressing member 30 can rotate in the vertical direction with respect to the terminal board 20 with the rotating portion 70 as a fulcrum.

[0105] On the other hand, in the terminal board unit 10A, the claw portion 31L is not provided on the left end of t...

[0116] Next, refer to Figure 4A to Figure 4C The terminal board unit 10B of the third embodiment of the present invention will be described. It should be noted that in the following description, the same components as those of the terminal board unit 10 of the first embodiment are assigned the same reference numerals to omit or simplify the description. The terminal board unit 10A of the second embodiment and the third The different points of the terminal board unit 10B of the embodiment will be described in detail.

[0117] Such as Figure 4A As shown, the terminal board unit 10B includes a first pressing member 30L and a second pressing member 30R. The first pressing member 30L extends in the left-right direction so as to cover the upper side of the mounting portions 21U, 21V, and 21W of the terminal board 20. In addition, the left end of the upper surface of the terminal board 20 and the left end of the first pressing member 30L are connected by the first rotating portion 7...

Abstract

The invention provides a terminal plate unit which is easy to manufacture a terminal plate and has excellent productivity. A terminal plate unit (10) is provided with: a first conductive member (40U,40V, 40W) each of which is provided with a first connection terminal (41U, 41V, 41W) at one end; a second conductive member (50U, 50V, 50W) provided with a second connection terminal (51U, 51V, 51W) at one end; a terminal plate (20) having a mounting section (21U, 21V, 21W) on which the first connection terminal (41U, 41V, 41W) and the second connection terminal (51U, 51V, 51W) are mounted; and apressing member (30) that is disposed so as to face the mounting section (21U, 21V, 21W) with the first connection terminal (41U, 41V, 41W) and the second connection terminal (51U, 51V, 51W) interposed therebetween. The first connection terminal (41U, 41V, 41W) and the second connection terminal (51U, 51V, 51W) are electrically connected by the connection parts (60U, 60V, 60W) by the pressing force of the pressing member (30) and are fixed to the terminal plate (20).

Description

Technical field [0001] The present invention relates to a terminal board unit used in a rotating electric machine and the like. Background technique [0002] Conventionally, electric vehicles and the like have been equipped with a rotating electric machine as a drive source. In addition, as a component for electrically connecting the rotating electric machine and a power conversion device for supplying electric power to the rotating electric machine, it is known to use a terminal board unit having a bus bar. [0003] For example, Patent Literature 1 discloses a terminal board unit suitable for connecting components and the like of a motor power supply of an electric vehicle. The terminal board unit of Patent Document 1 includes: a bus bar provided with at least two terminal portions electrically connected to a connection terminal arranged in an energizing circuit; a terminal board that holds and fastens the connection terminal to the terminal portion of the bus bar A square nut f...
