Description

[Detailed description of the invention] [Field of application of the invention] The invention is a vehicle generator (hereinafter referred to as a generator).
In particular, the present invention relates to the structure and manufacturing method of a brush holder for a generator.

[Background of the idea]

Regarding the configuration and manufacturing method of the generator's brush holder, application 59 was filed with the content that the molding resin for the brush storage box and other parts is thermosetting resin and thermoplastic resin, respectively.
-86732.

This application did not specifically cover the arrangement of the fixed brush connection terminals of the brush storage box.

[Purpose of invention]

The object of the present invention is to provide a brush holder that enables a highly reliable fixing method when a brush storage box molded from a thermosetting resin is integrally molded with a thermoplastic resin.

[Summary of the idea]

The storage box that stores the brushes is made of thermosetting resin, with an eave on the top of the storage box, a protruding band on the middle side, and a flange at the rear end of each eave and protruding band, each made of thermoplastic resin. A brush holder is constructed by fixing the brush storage box vertically, longitudinally, and horizontally.

[Example of idea]

Embodiments of the present invention will be described with reference to FIGS. 1 to 7.
FIG. 1 shows the overall structure of the brush holder. A connector 1 for connecting to the outside of the generator, a semiconductor voltage regulator 2, a brush storage box 4 that stores the brushes 3,
Connector 1 (not shown), semiconductor voltage regulator 2,
It is integrated with a terminal to which the brush 3 is connected. A brush storage box 4 for storing the brush 3 is molded in advance from thermosetting resin and covers the storage box 4, and the connector 4 and the voltage regulator 2 are integrated with thermoplastic resin. As shown in FIGS. 2 and 3, the brush storage box 4 has an eave shape 5 on both sides in the axial direction of the upper part of the storage box 4, and is provided with a flange 6a at the rear end of the eaves. Furthermore, a protruding band 7 having an inverted trapezoidal cross section is provided in the axial direction on the middle side of the storage box 4, and a flange 6b is provided at the rear end of the protruding band 7 as described above. Incidentally, the protruding band may have a substantially T-shaped cross section as shown in FIG. The brush storage box 4 is arranged so that the flanges 6a to 6b are on the side of the voltage regulator 4 shown in FIG. 1, and as shown in FIG. It is integrally molded so as to be covered with a plastic resin 8 (the part shown surrounded by a broken line). As a result, it is fixed in each of the front and rear, left and right, and up and down directions shown by the arrows.

Further, when arranging the terminal 9 that controls the connection between the brush 3 and the voltage regulator 2 on the upper part of the brush storage box 4 as shown in FIGS. An L-shaped convex band 10 is installed so as to serve as a barrier in the axial direction and in the direction perpendicular to the axis, thereby ensuring the insulation distance and positioning of the terminal 9 between different poles. As shown in FIG. 6, the illustrated part surrounded by the broken line is covered with thermoplastic resin to fix the terminal 9. Incidentally, the same effect can be obtained by using a brush storage box 4 provided with a groove 11 matching the shape of the terminal 9 as shown in FIG. 7 in place of the L-shaped convex band 10.

[Effect of idea]

According to the present invention, by providing the eaves, flange, and protruding band on the brush storage box made of thermosetting resin as shown in the above embodiment, the storage box can be securely fixed when integrally molded with thermoplastic resin. . Furthermore, by providing a partition between the terminals at the top of the storage box, the insulation distance between different poles can be secured and positioned, and the terminals can be fixed by covering them with thermoplastic resin.
