Abstract
The invention discloses a safety carbon brush of a starting motor of an automobile. The safety carbon brush of the starting motor of the automobile is composed of a left carbon body, a right carbon body, a left carbon brush wire, a right carbon brush wire and an angle plug, wherein a groove is formed in the top of the left carbon body, one end of the right carbon brush wire is connected with the right carbon body, one end of the left carbon brush wire is connected with the left carbon body, the other end of the left carbon brush wire and the other end of the right carbon brush wire are enwound together to be fixed in one end of the angle plug, and safety devices are further arranged inside the left carbon body and inside the right carbon body respectively. According to the safety carbon brush of the starting motor of the automobile, a power supply is cut off automatically when the carbon brush is abraded to the ultimate limit, and then safety of the motor is guaranteed.
Description
Technical field
The present invention relates to a kind of carbon brush, in particular for the insurance carbon brush of automobile start motor.
?
Background technology
Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and rotating part, in the time of electric machine rotation, electric energy is flowed to coil by phase changer.Carbon brush, as a kind of sliding contact part, is widely used in many electric equipments.Traditional carbon brush is generally that pure carbon adds coagulating agent and makes, and external form is generally square, and volume varies, and on top, has wire to draw.The automobile starter carbon brush is the sliding contact part of conduction current on the starter motor commutator, very easily wearing and tearing.In addition, prolongation in time of brush and constantly wearing and tearing, still can maintain energising when may wear to while imbedding terminal, make motor rotation, now, the commutator of motor directly and the wire termination friction, because commutator and wire are all metals, frictional resistance strengthens, and very easily produces heat and spark, cause burning commutator or make power supply short circuit, the dangerous accident such as breaking out of fire.
?
Summary of the invention
The objective of the invention is for solving existing issue above-mentioned.
For addressing the above problem, technical scheme of the present invention is: insurance carbon brush for a kind of automobile start motor, by left carbon body, right carbon body, left brush lead, right brush lead, the angle insert group becomes, a groove is arranged at the top of left carbon body, a groove is arranged at the top of right carbon body, one end of right brush lead is connected with right carbon body, one end of left brush lead is connected with left carbon body, it is characterized in that: the other end of left brush lead and the other end of right brush lead are intertwined, jointly be fixed in an end of inserting at angle, left carbon body and right carbon body inside also are provided with safeties, safeties are by insurance, relief spring forms, insuring sub bottom contacts with the bottom of carbon body internal holes, the bottom of relief spring wraps the sub-top of insurance, the top of relief spring contacts with the top of carbon body internal holes.
As a further improvement on the present invention, the groove at left carbon body and right carbon body top is " U " type groove.
As a further improvement on the present invention, insurance adopts high-strength insulating material.
As a further improvement on the present invention, brush lead is the copper braided wire, transferring energy that not only can be good and signal but also can reduce manufacturing cost.
To sum up, the present invention can guarantee the commutation stability of motor, extends the useful life of carbon brush, increases economic efficiency.When carbon brush abrasion arrives the limit, automatic cut-off power, guarantee the safety of motor, thereby extend the useful life of motor, has social benefit preferably.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, this automobile start motor is with insuring carbon brush by left carbon body 1, right carbon body 2, left brush lead 4, right brush lead 3, angle is inserted 5 and is formed, a groove 7 is arranged at the top of left carbon body 1, a groove 6 is arranged at the top of right carbon body 2, one end of right brush lead 3 is connected with right carbon body 2, one end of left brush lead 4 is connected with left carbon body 1, it is characterized in that: the other end of the other end of left brush lead 4 and right brush lead 3 is intertwined, jointly be fixed in an end at angle slotting 5, left carbon body 1 and right carbon body 2 inside also are provided with safeties, safeties 8 are by insurance 82, relief spring 81 forms, the bottom of insurance 82 contacts with the bottom of carbon body internal holes, the bottom of relief spring 81 wraps sub 82 tops of insurance, the top of relief spring 81 contacts with the top of carbon body internal holes, the top groove of left carbon body 1 and right carbon body 2 is " U " type groove, right brush lead 3 and left brush lead 4 are the copper braided wire, have good electric conductivity.
