New description: [New technical field] This creation is related to the motor back cover, especially the motor back cover which is easy to replace the carbon brush. [Prior Art] The motor rear cover of the shape generation has its carbon brush holder connected to the carbon brush at one end and the power supply line at the other end, and then the carbon brush holder is placed in the motor back cover. In the hole, this way, when the carbon brush wears out, it is impossible to directly replace the new carbon brush, and the carbon brush must be replaced together with the power cord, so that the cost will be increased; #, because of the carbon The brush retention system is directly connected to the power cord. Therefore, if the power cord is accidentally pulled when taken, the valley is likely to cause a break in the connection between the power cord and the carbon brush holder, and is not easy to detect, so often In the case of use, there is a motor failure. 15 [New content] The main purpose of this creation is to provide a motor back cover with a carbon brush holder that can be placed directly on the motor back cover, thus facilitating the replacement of carbon. brush. Another object of the present invention is to provide a motor back cover that can improve the lack of connection between the carbon brush holder and the power line due to the careful pulling of the power cord. In order to achieve the above objectives, the motor back cover of the present invention comprises: a set of rings, two guide pieces, a two-carbon brush, a two-carbon brush holder, two wires and a cover 'in which the ring The two corresponding places are respectively formed with a receiving portion of 4 M287017 ^ each of the holes is located on the same center line. The abdomen a is inserted through the inner and outer ring walls of the socket ring, and the two holes of the receiving hole are respectively connected to the hole. Slotting, in addition, one of the side walls of the hole is formed with an inner wall having a position of the upper two adjacent to the two accommodating holes, and a kiss that penetrates the ferrule and the accommodating hole The two guiding grooves are connected to each other; the two guiding pieces are respectively located on the inner wall of the connecting ring, and the two through holes are cut out for the second carbon brush, and the abutting contacts are abutted; And the guiding piece of each of the guiding pieces is exposed on the end of the inner wall of the socket ring; the current system 57 is not engaged with the opening edge of the receiving hole. [Embodiment] In order to explain the present invention more clearly, the preferred embodiment of the present invention is described in detail with reference to the following drawings, in which: Figure 1 is an exploded perspective view of a preferred embodiment of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a cross-sectional view of a preferred embodiment of the first embodiment coupled to a motor commutator. Please refer to the first to second figures of the present invention. The motor back cover (1) comprises a set of rings (10), two guide pieces (2 turns), and a two-carbon brush holder (30). Two carbon brushes (4 inches), two power cables (5 inches) and two covers (6 inches); wherein: the socket (10) is made of plastic, bakelite or other non-conductive material made of M287017, which Each of the two corresponding sleeves (10) is formed with a receiving hole (n), and the two receiving holes (11) are located on the same center line, and each of the receiving holes (u) runs through the sleeve ring. ( ίο) inner and outer ring walls, and two corresponding card slots (111) are formed on the opening edge side of the receiving hole (11) of the outer wall of the socket (1 〇), and each of the holes 5 (11) a receiving groove (12) is formed on one of the side walls; and a plurality of perforations (121) are respectively disposed on the upper side of the socket (10) adjacent to the two receiving holes (11), respectively The inner ring wall of the socket ring (10) and the inner wall of each of the accommodating holes (11) communicate with each of the accommodating grooves (121); one of the inner walls of the ferrule ring (1 〇) is attached to The socket ring (10) extends in the center direction to form a through hole (13) for the two power lines 10 (50) to pass through.One end of the two guiding tabs (2〇) is respectively located in the two receiving slots (12), and the other end is respectively passed through the two through holes (121) and exposed in the inner ring of the socket ring (1〇) wall. The two carbon brush holders (3〇) respectively have an abutting member (31), an impeller is (32) and a wire (33), and the two springs (32) and one of the two wires (33) The two abutting members (31) are respectively connected to the two abutting members (31); the two abutting members (31) are a metal plate piece, and one end thereof is formed with a flat and vertically bent plug portion (311): a two-carbon brush ( 40), one end of the two springs (32) and the two wires (33) are connected, when the two carbon brush holders (3) are placed in the two receiving holes (n), the two One end of the 20 piece (31) is resisted at the opening edge of the two receiving holes (11), and the two plugging portions (311) are respectively inserted into the two receiving grooves (12), and The two guiding pieces (20) are connected. One end of the two power lines (50) is respectively connected with a conductive terminal (5丨), and the two power lines (50) are passed through the through hole (13) of the sleeve ring (1〇), and the two 6 M287017 conductive terminals (51) are respectively inserted into the ends of the inner wall of the socket (1) exposed by the two guiding pieces (20); and the two power lines (5〇) are located in the through holes (Η) The inner part is sleeved by a wire buckle (52), and the two ends of the wire buckle (52) are placed at the two ends of the through hole (13), so that the two The power cable (5〇) is not easily pulled by 5; the second cover (60) is made of plastic or other non-conductive material, and is provided with corresponding latching bumps (61) for The card slot (11) of the socket (10) is fitted to close the opening of the outer wall of the receiving hole (11). Lu Weiyi, the above is the structure of each part of the motor back cover of a preferred embodiment, and then the usage mode and its characteristics are described as follows: 10 First, the two-carbon brush must be used first. And the two-carbon brush holder (30) is placed in the two receiving holes (n) by the outer wall of the sleeve ring (1), so that the abutting member of the two-carbon brush holder (30) (31) Resisting the opening of the two receiving holes (η), the plugs (311) are respectively inserted into the two receiving slots (12) to interfere with the two guiding tabs (20), and then The second cover (6 〇) closes the two accommodating holes (u), 15 so that the two carbon brushes (40) are in contact with the motor rotor (not shown), and can be used by the second elastic yellow (32) The elastic force and the resistance of the two abutting members (31) cause the two-carbon brush (40) to change its length due to continuous wear, and the two-carbon brush (4〇) still closely abuts the motor rotor; The power cord (5〇) of the present invention is passed through the through hole (13) of the socket (10) and then connected to each of the guiding pieces (2〇), because the two power lines (50) ) is not directly connected to the two-carbon brush holder (3〇) Therefore, it can be avoided that the wire between the two power wires (5〇) and the two-carbon brush holder (30) is broken due to improper pulling of the two power wires (50), so that a motor failure or the like occurs, and when the carbon brush (40) Wear to a certain length If you want to replace the carbon brush holder (30), you can easily replace the carbon brush (4〇), thus improving the shortcomings of the Xi 7 M287017 with the power cord. .
