Abstract

The utility model relates to a low-voltage DC motor, in particular to a leading-out line connection structure of low-voltage DC motor. A plurality of brushes is arranged on the brush plate along the circumferential direction, and each brush is provided with a brush pigtail. The brush plate is fixed in the end cover. With the position of anyone of the brushes as the starting position, the brush pigtails of brushes at the position of odd number are in serial connection with each other and led to the outside of terminal cover through the leading-outline clockwise or counterclockwise. The leading-out line is connected with the terminal cover in the way of insulation. Pigtails of brushes at the position of plural number are connected with the terminal cover. The leading-out line and terminal cover are connected with the anode and cathode of the DC power source respectively. With simple structure of leading-out line and low producing cost, the utility model solves the problems of the current DC motors such as complicated structure of leading-out line and high producing cost.

Description

Low voltage DC motor lead-out wire syndeton
Technical field
The utility model relates to a kind of low voltage DC motor, particularly a kind of low voltage DC motor lead-out wire syndeton.
Technical background
Brush direct current motor is provided with several brushes, and several brushes are divided into two groups, and the brush pigtail of every group of brush links together and is provided with a lead-out wire, and the lead-out wire of two groups of brushes leads to end cap and is connected with the both positive and negative polarity of DC power supply respectively more outward.The direct current machine of said structure exists the lead-out wire structure comparatively complicated, and manufacturing cost is relatively than problems such as height.
Summary of the invention
The utility model purpose is to provide a kind of lead-out wire structure comparatively simple, makes lower-cost low voltage DC motor lead-out wire syndeton, and the lead-out wire structure that has solved existing direct current machine existence is comparatively complicated, and manufacturing cost is relatively than problems such as height.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the even number brush along the circumferential direction is evenly arranged on the brush holder plate, each brush is provided with the brush pigtail, the brush holder plate is fixed in the end cap, with the position at any one brush place wherein is original position, the brush pigtail that is in the brush of odd positions clockwise or counterclockwise is cascaded mutually and leads to outside the end cap by lead-out wire, insulate between lead-out wire and the end cap and be connected, the brush brush pigtail that is in the even number position is connected electrically on the end cap, and lead-out wire and end cap are electrically connected with the both positive and negative polarity of DC power supply respectively.When the operating voltage of direct current machine is in human safety voltage's scope, the brush brush pigtail that wherein is positioned at the even number position directly is connected on the end cap as a utmost point, the brush brush pigtail of even number position also can directly be connected on the motor case, and the brush brush pigtail that is in odd positions links together and is connected with lead-out wire, whole motor only needs a lead-out wire, simplify the lead-out wire structure of low voltage DC motor, and reduced the manufacturing cost of low voltage DC motor.
As preferably, described end cap is provided with the bolt that insulation with it connects, and the head end of bolt is positioned at end cap and is electrically connected with the brush brush pigtail that is in odd positions, and the end of thread of described bolt is positioned at end cap and is electrically connected with lead-out wire one end outward.
As preferably, the number of described brush is 2,4 or 6.
Therefore, it is comparatively simple to the utlity model has the lead-out wire structure, makes characteristics such as cost is lower.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, four brush 1-1,1-2,1-3 and 1-4 along the circumferential direction are evenly arranged on the brush holder plate 2, each brush is provided with brush pigtail 3, brush holder plate 2 is fixed in the end cap 4, position with brush 1-1 place is initial primary importance, the brush pigtail 3 that is in the brush 1-1 of odd positions and brush 1-3 along clockwise direction is cascaded mutually to be connected and is connected electrically in the head that bolt 5 is positioned at end cap 4, end cap is provided with the bolt that insulation with it connects, and the end of thread of bolt 5 is positioned at the end cap 4 outer lead-out wires 6 that pass through and is electrically connected with dc power anode; 3 of brush pigtails that are in the brush 1-2 of even number position and brush 1-4 are welded in and are connected electrically on the end cap 4, and end cap 4 is connected with the negative electricity of DC power supply.
