Each of the electrode plates is assembled by being inserted into the electrode plate support groove from the other end, and the height of the electrode plate support groove is greater than the thickness of the electrode plate. It is large, and the width of the groove is thicker (than the width of the electrode plate).
Further, the electrode plate has a protrusion in its middle portion that engages with the entrance of the electrode plate support groove, and a cut-out portion or an equivalent groove engagement means is provided in front of the protrusion, whereby the electrode plate is incorporated into the groove with a slight slack.

Hereinafter, to explain the contents of the present invention with reference to the drawings, the device according to the present invention includes a housing 2 that accommodates a pair of brushes 1 therein, a housing 2 that is integrally molded with the housing on one side of the housing, and a rotating machine such as a generator. A current collector main body 4 consisting of a flange portion 3 that can be attached to the main body, and a pair of conductive plates 5 that form external connection terminals that are attached to the current collector main body.
It consists of.

The housing 2 includes therein a vertical passage corresponding to the cross-sectional shape of the brush 1, and the brush is disposed within the passage, with one end thereof protruding toward the rotor, and the brush being pulled out from the other end. A wire 6 is connected to the plate via a loop-shaped slack through the lower part of the upper part of the housing.

A compression coil spring is disposed between the brush and the housing around the leader wire in the housing to adjust the amount of protrusion of the brush.

As shown in the figure, the electrode plate 5 has a flat plate shape;
゛At one end of the horizontal flat plate, there is a leader line 6 from the brush.
A hole 8 is formed therethrough, and the other end has a shape (indicated by A) corresponding to the shape of the terminal of the external socket so that an external socket can be directly connected thereto.

Further, a pair of protrusions 9 are formed on both sides of the middle part of the electrode plate, and a cut-out part 10 is formed in the central part in front of the protrusions.
are formed, and these form means for integration into the current collector body, as will be described below.

When the above-mentioned electrode plate is assembled into the current collector main body, the other end is moved away from the current collector main body so that the electrode plate has an S
``Extends at right angles to facilitate connection with external sockets.

Further, the flange portion 3 is connected to the housing 2 as shown in the figure.
It extends across the width direction, has attachment portions 11 to the rotating machine main body near both left and right ends thereof, and has a structure in which the electrode plate 5 is incorporated with some slack.

That is, a plate support part 12 is provided above each of the mounting parts 11 and is integrally molded with the flange part 3 and the housing 2, and each plate support part is attached to the housing 2 as shown in FIGS. a side support portion 13 spaced laterally outwardly from the side surface of the housing, and an upper support portion 14 and a lower support portion 15 vertically staggered between the side surface of the housing and the side support portion; The side support part, the upper support part, and the lower support part of the plate support part are provided with a lateral plate support groove 1 extending in a direction S perpendicular to the axis of the brush, between the side support part, the upper support part, and the lower support part of the plate support part and the side surface of the housing.
6 is formed.

The height of the groove 16 is larger than the thickness of the electrode plate, and the width of the groove is wider than the width of the electrode plate.

Therefore, when each electrode plate is aligned with the entrance of the groove 16 and pressed in the direction shown by P in FIG. comes into contact with the entrance of the groove, and its forward movement is stopped. At this time, the side raised portion expands within the intermediate space of the lower part 15 of the block, and its backward movement is also stopped, eventually causing the plate to Although it can be installed in a predetermined position relative to the current collector body, the installed plate can move within a predetermined range relative to the current collector body.

Now, in order to assemble the current collector, each electrode plate is assembled into the groove 16 from one flat end as described above, the brush 1 is positioned in the housing, and the lead wire 6 from the end of the brush is inserted.
is inserted into the hole 8 of the electrode plate through the hole 7, and the tip of the lead wire is fixed to the electrode plate by soldering or the like.

The current collector created in this way does not require conventional relay terminals, conducting wires, connectors, bolts, washers, embedded nuts, etc., and can significantly reduce the number of components required in conventional devices. The 28 parts listed above can be covered with just 7 parts.

Furthermore, since the terminals for external connection can be swung within a desired fixed range with respect to the current collector main body, even if the dimensions of the mating terminals change somewhat, these terminals can be easily connected without being damaged.

Furthermore, in the present invention, the plate support grooves 16 are arranged at the side support portion 13 spaced laterally outward from the housing side surface, and at the upper side, which are alternately arranged vertically between the housing side surface and the side support portion 13. Since it is formed by the support portion 14 and the lower support portion 15, the plate support groove 16 can be molded by die cutting in the same direction as the brush passage and opening lower portion of the housing 2, that is, in the vertical direction. Therefore, it is sufficient to use two cutting dies, upper and lower, for molding the current collector main body 4, and thereby the current collector main body can be manufactured easily and at low cost.

In addition, since the electrode plate support groove 16 is formed on the side of the brush storage housing 2, the electrode plate 5 can be easily assembled into the current collector body 4 by insertion, and at the same time, the current can be passed between the brush 1 and the electrode plate 5. Connection can be made using a leader line 6 with a large capacity.

Furthermore, since the plate 5 is inserted into the plate support groove 16 from the flat end, the other end of the plate 5 has either a male terminal or a female terminal, depending on the mating terminal. can also be formed.

Furthermore, since the insertion end of the electrode plate 5 incorporated into the electrode plate support groove 16 is made of a horizontal flat plate, the terminal 5 at the other end of the electrode plate is at right angles to the axis of the brush 1 or at right angles to the axis of the brush 1. It can be oriented so that it extends in parallel directions.

Although the above embodiment has been described as a current collector for a single-phase electrode, it is obvious to those skilled in the art that this can be modified and applied to a device for multi-phase electrodes.

As described above, according to the present invention, the number of component parts in the current collector of a rotating machine can be significantly reduced.
Therefore, the overall manufacturing cost can be reduced, and various practical effects can be obtained, such as being able to easily adapt to slight changes in the dimensions of the mating terminal.
