Abstract

The utility model relates to a motor conduction structure, which belongs to the electromechanical class. A carbon brush mount is connected with a metal conductor of the wires; the metal conductor of the wires is welded to the carbon brush mount in the method of high-temperature spot welding; the welding point is high temperature-resistant and vibration-resistant, the tightly-welded solder joint will not be affected by the high temperature and vibration produced by the friction of the carbon brush and the rotor, the vibration produced by the own rotor of the motor and the high temperature produced inside the motor during the operation of the motor. The carbon brush mount can be further designed into the carbon brush mount with a changeable carbon brush, the carbon brush mount with a fixed carbon brush or the carbon brush mount for mechanical motors of relevant machines. The utility model has the advantages that: the connectors of extra devices is not required for the carbon brush mount; the wires and the carbon brush mount are fixed in the method of spot jointing; the jointing temperature of spot jointing being high, the welded solder joint is not affected by the high temperature of motor operation; the wires are hard to shed and the fabrication cost of the motor is reduced.

Description

The motor conducting structure

Technical field

The utility model relates to electrical category, particularly a kind of motor conducting structure.

Background technology

As shown in Figure 1, carbon brush formula motor commonly used, on motor lid A, must be provided with the carbon brush holder B of corresponding motor number of poles, for making external power can be transferred to carbon brush holder B smoothly, generally on carbon brush holder B, be equiped with connector C, after the metallic conductor D1 of lead D penetrated connector C, metallic conductor D1 and connector C are given solid welding with scolding tin E; But general motor is when running, and carbon brush holder B inside contacts with rotor with carbon brush, and in running up friction down, it easily produces high heat, during motor itself running simultaneously, produces high heat relatively; And about 150 degree of general scolding tin E fusing point when running into motor temperature when too high, will make scolding tin E fusing, be again high vibrating state in the motor running, easily cause metallic conductor D1 and the connector C generation obscission of lead D, need be improved.

The utility model content

The purpose of this utility model is to provide a kind of motor conducting structure, has solved existing motor running temperature and has easily caused melts soldering tin, lead easily to separate with connector when higher causing producing between lead and motor shell problems such as short circuit.

The technical solution of the utility model is: carbon brush holder is connected with the metallic conductor of lead, spot welding mode with high temperature, the metallic conductor of lead is welded on the carbon brush holder, solid welding point after the solid welding is high temperature resistant, anti-vibration, so when motor running, high temperature that the friction of carbon brush and rotor is produced and vibrations, vibrations that self rotor of motor produced and the high temperature of motor inside etc., solid welding is named a person for a particular job and not influenced by above-mentioned situation; Carbon brush holder further is made as the carbon brush holder of replaceable carbon brush, the fixing carbon brush holder of the carbon brush holder of carbon brush or associated motor machinery motor.

Advantage of the present utility model is: carbon brush holder does not need the extra means connector, with the mode fixing cord and the carbon brush holder of spot welding; The welding temperature height of spot welding, the solder joint of welding is not subjected to the temperatures involved of motor running; Lead does not have the misgivings that come off, and has reduced the motor cost of manufacture.

Fig. 2 is carbon brush holder of the present utility model and lead connection diagram;

Fig. 3 to Fig. 5 is a connection procedure schematic diagram of the present utility model;

Fig. 6 is an embodiment schematic diagram of the present utility model.

Embodiment:

As shown in Figure 2, carbon brush holder B is connected with the metallic conductor D1 of lead D, spot welding mode with high temperature, the metallic conductor D1 of lead D is welded on the carbon brush holder B, high temperature resistant, the anti-vibration of solid welding point F after the solid welding, so when motor running, high temperature that the friction of carbon brush and rotor is produced and vibrations, vibrations that self rotor of motor produced and the high temperature of motor inside etc., solid welding point F will not be influenced by above-mentioned situation will; Carbon brush holder B further is made as the carbon brush holder of replaceable carbon brush, the fixing carbon brush holder of the carbon brush holder of carbon brush or associated motor machinery motor.

As shown in Figures 3 to 5, carbon brush holder B is provided with solder side B1, and the metallic conductor D1 of lead D is placed on the solder side, and G presses to metallic conductor D1 with the spot welding device, make on its solder side B1 that is welded in carbon brush holder B, so do not need tradition to connect lead D and carbon brush holder B in modes such as connectors.

As shown in Figure 6, connected mode between number carbon brush holder B and lead D, the metallic conductor D1 of lead D is welded on the carbon brush holder B in the mode of spot welding, its solid welding point F is the spot welding mode of high temperature, solid welding point F after the solid welding is high temperature resistant and anti-vibration, so during motor running, the high temperature that the friction of carbon brush and rotor is produced and vibrations, vibrations that self rotor of motor produced, and the high temperature of motor inside etc., solid welding point F will not be influenced by above-mentioned situation will.

Claims

1, a kind of motor conducting structure, carbon brush holder is provided with solder side, and the metallic conductor of lead places on the solder side, it is characterized in that: the metallic conductor of lead is welded on the carbon brush holder.

2, a kind of motor conducting structure according to claim 1 is characterized in that: said carbon brush holder is made as the carbon brush holder of replacing carbon brush, the fixedly carbon brush holder of carbon brush or the carbon brush holder of electromechanics motor.
