Abstract

A carbon brush is installed in a carbon brush installation hole of a carbon brush frame, more than two wires are die-cast at the connecting end of the carbon brush, 3-4 wires can be used, a connecting hole of each wire is welded or riveted on the connecting frame of the carbon brush frame, and an end cap clamps the end part of the carbon brush installation hole. The carbon brush has the advantages that the number of the connecting wires behind each carbon brush is increased to two or more than two from the original one, the connecting strength between the carbon brush and the connecting wires and between the connecting frames of the connecting wires and the carbon brush frame is greatly enhanced compared with the original connecting strength, and when one of the connecting wires is short due to fatigue, the other connecting wire can also play a role in conducting electricity, so that the service life of the carbon brush is prolonged. The carbon brush wire has low cost, so that the cost of the whole generator is hardly influenced after the carbon brush wire is added, but the service life of the generator can be greatly prolonged.

Description

Carbon brush connecting structure of alternating current generator for vehicle

Technical Field

The utility model relates to an automobile-used alternator carbon brush connection structure is suitable for various automobile-used generators that brush.

Background

In the existing carbon brush structure of the vehicle alternating current generator, the rear part of the carbon brush is connected with a wire, then the wire of the carbon brush is welded on a carbon brush frame, and the carbon brush is propped against a collector ring of a generator rotor by the elasticity of a spring. Because the generator works between 3000-6000 rmp for a long time, the rotor collecting ring rotates synchronously with the generator, the carbon brush is in contact with the collecting ring, and the carbon brush vibrates due to long-time rotation or excessive jumping of the rotor shaft and the collecting ring, so that the carbon brush and the lead are broken off due to fatigue. In addition, the vibration amplitude of the carbon brush in the carbon brush frame can be increased due to the vibration of the engine, and the carbon brush connecting wire can be broken due to fatigue after long-time operation, so that the generator cannot generate electricity.

Disclosure of Invention

An object of the utility model is to solve the above-mentioned current problem that exists, provide an increase of service life's automobile-used alternator carbon brush connection structure.

The utility model discloses a realize like this: the carbon brush is installed in the carbon brush installation hole of the carbon brush frame, the connecting end of the carbon brush is die-cast with more than two wires, the connecting hole of each wire is welded or riveted on the connecting frame of the carbon brush frame, and the end cap clamps the end part of the carbon brush installation hole.

The utility model discloses the advantage is, the connecting wire behind every carbon brush is increased to two or more than two by original one, and the joint strength between the link of carbon brush and wire and carbon brush holder is great reinforcing before, and one of them is because tired book is short, and another one also can play the electrically conductive effect to increase the life of carbon brush. The carbon brush wire has low cost, so that the cost of the whole generator is hardly influenced after the carbon brush wire is added, but the service life of the generator can be greatly prolonged.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of the connection between the carbon brush and the conductive wire;

fig. 3 is a right side view of fig. 2.

Detailed Description

The following detailed description is made with reference to the accompanying drawing 1: as shown in the figure, the carbon brush 1 is installed in a carbon brush installation hole of the carbon brush frame 4, more than two wires 2 or 3-4 wires are die-cast at the connecting end of the carbon brush 1, a connecting hole 3 of each wire 2 is welded or riveted on a connecting frame 5 of the carbon brush frame 4, and an end cap 6 clamps the end part of the carbon brush installation hole.

When the carbon brush is used, when one of the wires 2 is broken due to fatigue, the other wire can also play a role in conducting electricity, so that the service life of the carbon brush is prolonged.

Claims
