Abstract
The utility model discloses a composite carbon brush for an electric pick. The composite carbon brush comprises a carbon body, a lead, a connecting spring, a connection piece and a copper bush, wherein the carbon body includes a left carbon block and a right carbon block which are symmetrical, an adhering layer is arranged between the left carbon block and the right carbon block, the left carbon block and the right carbon are adhered into a whole through the adhering layer, a protrusion is respectively disposed on the upper portions of the left carbon block and the right carbon block, the copper bush is sleeved on the upper portion of the carbon body and fastened on the carbon body through the two protrusions, a left lead and a right lead are welded on the copper bush, the left lead and the right lead are intertwined to form the lead to penetrate the connecting spring to be connected with the connection piece, one end of the connecting spring contacts with the connection piece, and the other end of the connecting spring contacts with the copper bush. The copper bush is sleeved on the carbon body, the lead the spring and the connection piece on the copper bush and the copper bush are recyclable, accordingly the cost is reduced, and environmental pollution is decreased. Besides, the insulation cement layer is arranged between the left carbon body and the right carbon body, so that the reversing performance of the carbon brush is improved.
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.When motor runs up, because the thermal coefficient of expansion of carbon brush is less, cause the card brush easily, cause motor commutation unstable; And 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.
The utility model content
The technical problem that the utility model will solve provides a kind of electric pick that commutates stable and economical with materials and uses compound carbon brush.
For addressing the above problem; The technical scheme that the utility model adopts is: a kind of electric pick is used compound carbon brush; Comprise carbon body, lead, connection spring and contact pin; Said carbon body comprises the carbon piece left side carbon piece and the right carbon piece of two symmetries, is provided with adhesive layer between two carbon pieces, and two carbon pieces are bonded into an integral body through adhesive layer; Also comprise copper sheathing, the position of left carbon piece and right carbon piece top symmetry has a protrusion respectively, and copper sheathing is enclosed within carbon body top; Be stuck on the carbon body by two protrusions; Be welded with left lead and right lead on the copper sheathing respectively, left lead and right lead are wound in lead each other, pass the connection spring and are connected with contact pin; An end that connects spring contacts with contact pin, and the other end contacts with copper sheathing.
As a kind of improvement of the utility model, said adhesive layer is the insulation glue-line.
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; In the middle of the carbon body, add the insulation glue-line, can improve the commutation ability of carbon brush.
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 compound carbon brush; Comprise carbon body 1, lead 2, connect spring 3 and contact pin 4; Said carbon body 1 comprises the carbon piece left side carbon piece 11 and right carbon piece 12 of two symmetries; Be provided with 13, two carbon pieces of adhesive layer between two carbon pieces and be bonded into an integral body through adhesive layer 13, the adhesive layer material therefor is an insulating cement; Also comprise copper sheathing 5, the position of left carbon piece 11 and right carbon piece 12 tops symmetry has a protrusion 14 respectively, and copper sheathing 5 is enclosed within carbon body 1 top; Be stuck on the carbon body 1 by two protrusions 14; Be welded with left lead 6 and right lead 7 on the copper sheathing 5 respectively, left lead 6 is wound in lead 2 each other with right lead 7, passes connection spring 3 and is connected with contact pin 4; An end that connects spring 3 contacts with contact pin 4, and the other end contacts with copper sheathing 5.Lead 2 is a copper core flexible cord, and contact pin 4 is latten(-tin).This electric pick puts a copper sheathing with compound 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; In the middle of the carbon body, add the insulation glue-line, can improve the commutation ability of carbon brush.
