Abstract
An integrated carbon brush holder structure belongs to the technical field of manufacturing of motor matching parts, and mainly comprises a carbon brush insulator (3), a positive metal insert (1) and a negative metal insert (2) which are embedded in the carbon brush insulator (3), and the like, wherein the positive metal insert (1) is used for connecting and conducting a carbon brush under the positive polarity of a motor, and the negative metal insert (2) is used for connecting and conducting a carbon brush under the negative polarity of the motor; the positive metal insert and the negative metal insert are integrally injection-molded with the insulator. The utility model discloses an overcome the not high not enough of a great deal of potential safety hazard and the system reliability of current carbon brush frame structure, make the sheetmetal of connecting the same polarity by whole injection moulding integrative, the sheetmetal of different polarities is kept apart by engineering plastic insulation, has guaranteed firm and the electric unobstructed on the machinery. Not only can improve the production efficiency and greatly reduce the reject ratio, but also fundamentally improve the reliability of the system.
Description
Technical field
The utility model relates to a kind of integrated carbon brush holder structure, belongs to the manufacturing technology field of electric drilling match parts.
Background technology
At present, the carbon brush holder structure in known four utmost points and the above number of poles motor is single.In order to realize that power delivery is arrived armature winding, generally carbon brush is contained in the carbon brush holder carbon brush chamber, carbon brush is pressed on commutator face by spring, and the carbon brush under the identical polar is communicated with (general by welding) by lead.Therefore, the welding of lead need be wasted man-hour, there are potential hidden danger of quality such as rosin joint, dry joint, assembling are damaged, off-line simultaneously, at motor continuously or after intermittent operation a period of time in cycle, because major defects such as situations such as the motor feels hot, vibration, the accumulation of carbon brush powder also might cause loose contact of motor electrical connections even short circuit, open circuit have reduced the reliability of using.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, guarantees carbon brush holder and reliable, the unseparated integrated carbon brush holder structure of electrical connections in the whole service process of motor.
The integrated carbon brush holder structure of the utility model, comprise the carbon brush insulator, it is characterized in that being embedded with in the carbon brush insulator cathode metal inserts and negative pole metal insert, the cathode metal inserts connects conducting with the carbon brush under the anodal polarity of motor, and the negative pole metal insert connects conducting with the carbon brush under the motor negative pole polarity; Cathode metal inserts and negative pole metal insert and insulator are overall injected into a whole.
The utility model is in order to overcome existing many potential safety hazards of carbon brush holder structure and the not high deficiency of system reliability, the union body of the carbon brush under the identical polar is made into the sheet metal (mostly being copper sheet) of definite shape, be overall injected into a whole with engineering plastics, the sheet metal that connects identical polar is overall injected into a whole, the sheet metal of opposed polarity is isolated by the engineering plastics insulation, like this, carbon brush holder and electrical connections are inseparable, guaranteed mechanically firm and electric on unobstructed.Both can enhance productivity, and greatly reduce fraction defective, and fundamentally improve the reliability of system again, this more has significant effect in the extra high motor of reliability requirement (the ABS motor that uses in as anti-locking system for car).
Description of drawings
Accompanying drawing is an overall structure schematic diagram of the present utility model.
Embodiment
The utility model is mainly by carbon brush insulator 3, be embedded at formations such as cathode metal inserts 1 in the carbon brush insulator 3 and negative pole metal insert 2, cathode metal inserts 1 connects conducting with the carbon brush under the anodal polarity of motor, and negative pole metal insert 2 connects conducting with the carbon brush under the motor negative pole polarity; Cathode metal inserts 1 and negative pole metal insert 2 are overall injected into a whole with insulator 3.
Claims (1)
1, a kind of integrated carbon brush holder structure, comprise carbon brush insulator (3), it is characterized in that being embedded with in the carbon brush insulator (3) cathode metal inserts (1) and negative pole metal insert (2), cathode metal inserts (1) connects conducting with the carbon brush under the anodal polarity of motor, and negative pole metal insert (2) connects conducting with the carbon brush under the motor negative pole polarity; Cathode metal inserts (1) and negative pole metal insert (2) are overall injected into a whole with insulator (3).
