Abstract
The utility model discloses a novel carbon brush for an electric pick. The novel carbon brush comprises a carbon body, a lead wire, a connecting spring, a contact pin and a copper bushing, wherein two symmetrical bulges are arranged on the side surface of the upper part of the carbon body; the copper bushing is sleeved at the upper part of the carbon body and clamped on the carbon body by the two symmetrical bulges; a raised cylindrical lug boss is arranged on the copper bushing; one end of the connecting spring is fixed on the contact pin, and the other end of the connecting spring wraps the cylindrical lug boss on the copper sleeve and is in contact with the copper sleeve; one end of the lead wire is welded on the contact pin, and the other end of the lead wire passes through the connecting spring and is connected with the copper sleeve; and the contact pin is made of phosphor copper. According to the novel carbon brush disclosed by the utility model, because the copper sleeve is sleeved on the carbon body and the lead wire is led out of the copper sleeve, when the carbon brush is abraded to a certain degree and needs to the replaced, only is the carbon body required to be replaced, and the copper sleeve as well as the lead wire, the spring and the contact pin arranged on the copper sleeve can be recycled, therefore the cost and the environmental pollution are reduced. The carbon brush using the contact pin made of the phosphor copper is in better contact with a motor, is not easy to deform after being used for a long time and can ensure operating stability of the motor.
Description
Technical field
The utility model relates to a kind of carbon brush, in particular for the carbon brush of electric hammer.
Background technology
Carbon brush is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, when motor rotates, electric energy is flowed to coil through phase changer.Carbon brush is widely used in many electric equipments as a kind of sliding contact part.Traditional carbon brush generally is that pure carbon adds coagulating agent and processes, and external form generally is a square, and volume varies, and has lead to draw on the top, and wire bonds is on joint, and the joint another side then is fixed on the brush nest through connecting spring.After the wearing and tearing of carbon body, carbon brush all must all be changed together with the lead on the carbon brush, spring and joint, and lead, spring and joint all are to be processed by heavy metal, can cause environmental pollution after abandoning, and are unfavorable for environmental protection and saving.And contact pin is processed with latten(-tin) often, and latten(-tin) has good ductility and conductivity, and is easy to process, but hardness is lower, and the long-term back easy deformation of using influences motor performance.
The utility model content
The technical problem that the utility model will solve provides a kind of electric pick that needs to change the carbon body and uses novel carbon brush.
For addressing the above problem, the technical scheme that the utility model adopts is: a kind of electric pick is used novel carbon brush, comprises carbon body, lead, connection spring and contact pin; Also comprise copper sheathing, carbon body upper side has the protrusion of two symmetries, and copper sheathing is enclosed within carbon body top; Be stuck on the carbon body by the protrusion of two symmetries, the cylindrical boss of a protrusion is arranged on the copper sheathing, an end that connects spring is fixed in the contact pin; Cylindrical boss on the other end parcel copper sheathing also contacts with copper sheathing; One end of lead is welded in the contact pin, and the other end passes the connection spring and is connected with copper sheathing, and said contact pin material therefor is a phosphor-copper.
As a kind of improvement of the utility model, said lead is a copper core flexible cord.
As a kind of improvement of the utility model, said contact pin is latten(-tin).
The utility model puts a copper sheathing on the carbon body; Lead is drawn from copper sheathing, does not influence the function of carbon brush like this, when carbon brush may wear to a certain degree need change the time; Only needing to change the carbon body gets final product; Copper sheathing is all reusable together with top lead, spring and contact pin, not only reduces cost, and reduces environmental pollution; The protrusion of two symmetries that design on the carbon body can tightly be stuck in copper sheathing on the carbon body, and copper sheathing is unlikely during use comes off.Use the carbon brush of phosphor-copper contact pin better with contacting of motor, long-term use is not yielding, can guarantee that motor is stable.
Description of drawings
Accompanying drawing 1 is the generalized section of the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
This electric pick is used novel carbon brush, comprises carbon body 1, lead 2, connects spring 3 and contact pin 4, also comprises copper sheathing 5; Carbon body 1 upper side has the protrusion 6 of two symmetries, and copper sheathing 5 is enclosed within carbon body 1 top, is stuck on the carbon body 1 by the protrusion 6 of two symmetries; The cylindrical boss 7 that one protrusion is arranged on the copper sheathing 5, the high 5mm of cylindrical boss, an end that connects spring 3 is fixed in the contact pin 4; Cylindrical boss 7 on the other end parcel copper sheathing 5 also contact with copper sheathing 5, and an end of lead 2 is welded in the contact pin 4, and the other end passes connection spring 3 and is connected with copper sheathing 5; Lead is a copper core flexible cord, and contact pin is phosphorus bronze sheet.This electric pick puts a copper sheathing with novel carbon brush on the carbon body; Lead is drawn from copper sheathing, does not influence the function of carbon brush like this, when carbon brush may wear to a certain degree need change the time; Only needing to change the carbon body gets final product; Copper sheathing is all reusable together with top lead, spring and contact pin, not only reduces cost, and reduces environmental pollution.
