Abstract
The utility model discloses an electric brush assembly, which comprises a motor end cover. The motor end cover is circumferentially provided with an electric brush chamber and a lateral support. An electric brush body is arranged in the electric brush chamber. The lateral support is provided with an electric brush conducting strip. The electric brush body and the electric brush conducting strip are connected through a lead. The electric brush assembly is characterized in that the top of the electric brush conducting strip is provided with a pressing hook compaction lead. The pressing hook fuses to fix the lead. In this way, the problem that a conventional electric brush conducting strip and a lead are high in welding cost and poor in accuracy when to be connected together can be solved.
Description
Technical field
The utility model relates to a kind of brush assembly of electric.
Background technology
Motor is more extensive in routine use, and be all much brush motor in present motor, on the end cap of motor, be provided with brush, brush is the parts that brush motor the inside withstands on phase changer surface, in the time of electric machine rotation, electric energy is flowed to rotor coil by phase changer, and general brush is all comprised of brush body and brush conducting strip, by wire, connect between the two, in present enterprise, between wire and brush conducting strip, conventionally utilize the mode of soldering, it is certain not enough that but this class welding exists, first, soldering need to be melted with kamash alloy, infiltrate and gap, added metal part junction, this is a kind of welding of filled type, need raw material kamash alloy, secondly, soldering is generally artificial welding, artificial welding sequence is more, and precision is wayward.
Utility model content
The utility model technical issues that need to address are, a kind of brush assembly of electric is provided, and have solved while being connected between conventional brush conducting strip and wire welding cost higher, the problem that precision is bad.
The technical solution of the utility model is: a kind of brush assembly of electric, comprise electric motor end cap, described electric motor end cap is along being circumferentially with brush room and side supports, brush is provided with brush body within doors, side supports is provided with brush conducting strip, between described brush body and brush conducting strip, by wire, be connected, it is characterized in that: described brush conducting strip top is provided with pressure hook and compresses wire, wire is fixed in pressure hook fusion.
Preferably, described brush conducting strip medial side face place is provided with guiding fixed groove, described side supports is provided with 2 the fixed guide fixed columns corresponding with the fixed groove that leads, and the fixed groove that leads in the time of in brush conducting strip insertion side supports can be stuck on fixed guide fixed column.
Preferably, described brush conducting strip tail end is provided with the terminal plug hole of perforation, facilitates some terminals to insert, such as 250 female terminals.
Adopt after the technical program, L-type pressure hook on brush conducting strip is and struts shape when wire is not placed into L-type inner space, when wire is put into L-type inner space, utilize manipulator that pressure hook is pressed with wire and compressed, now instantaneous high electric current in addition on pressure hook, high electric current is by the pressure hook melting of L-type, the pressure hook of melting is connected with the wire in L-type space automatically, so just saved this welding raw material of kamash alloy, manipulator is pressed simultaneously, instantaneous these operations of high electric current can be completed with the automatic equipment of streamline, replace artificial welding, time and labour saving order, precision is also high.
Accompanying drawing explanation
Schematic three dimensional views when accompanying drawing 3 does not connect wire for brush conducting strip;
Accompanying drawing 4 is the schematic diagram of brush conducting strip connection wire.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 4, brush assembly of electric mainly comprises brush body 4 and brush conducting strip 1, by wire 2, connect between the two, all be arranged on separately on electric motor end cap, its center brush body 4 is arranged in the brush room 52 of electric motor end cap, and can be active in the internal cavities in brush room 52, 1 of brush conducting strip is fixed in the side supports 51 of electric motor end cap, brush room 52 and side supports 51 are circumferentially distributed on electric motor end cap, this routine center brush room and side supports have respectively 2, on electric motor end cap, be fixed with torsion spring 3, the spring arm end of torsion spring 3 props up the tail end of brush body 4, make it not depart from brush room 52, the tail end of its center brush body 4 has end difference 41, the spring arm end of torsion spring 3 just can drop in stage portion 41, stage portion plays good supporting role to the spring arm end of torsion spring, the side of stage portion connects a wire 2, the other end of wire 2 is connected with brush conducting strip 1, brush conducting strip 1 is being provided with the pressure hook 11 of L-type with connecting position of wires, this pressure hook 11 is and struts shape when wire does not connect, L-type pressure hook is integrated compared with minor face and brush conducting strip 11, longer sides is and struts shape above brush conducting strip, in the time of in wire is positioned over the space between longer sides and brush conducting strip, longer sides in top is depressed, until wire is pressed tight, now instantaneous high electric current in addition up, pressure hook 11 itself is heated melting, together with melting with wire subsequently, form and connect, the mode advantage of the artificial soldering with respect to routine of such design is, first, the welding raw material of kamash alloy while having saved soldering, reduce costs, secondly artificial soldering operation is many, and precision is not high, easily cause rosin joint, and by the structure of L-type pressure hook, instantaneous high electric current in addition, because its welding position is fixed, can automatically clamp with manipulator, then pass to high electric current of moment, can realize automation mechanized operation, save artificial soldering, and precision is higher, brush conducting strip 1 is provided with guiding fixed groove 12 at place, middle two sides, in side supports 51 on the electric motor end cap of answering in contrast, there are two fixed guide fixed columns, when brush conducting strip inserts downwards, two fixed guide fixed columns are stuck in guiding fixed groove, and with riveted joint mode fixed guide fixed column is rivetted, brush conducting strip is fixed in side supports 51, the positive bottom of brush conducting strip is provided with a terminal plug hole 13, be used for facilitating some terminals to insert, such as 250 female terminals of standard.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure allows to change, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
