Abstract
The utility model discloses a carbon brush sleeve for a DC motor. The carbon brush sleeve is installed on an end face on which the motor carbon brush is disposed; the carbon brush sleeve is a thin plate-shaped sleeve body made of an insulating material and includes a thin bottom plate, a plurality of isolated convex sleeves for fastening pieces and isolated convex sleeves for front and back carbon brush bodies; the isolated convex sleeves for front and back carbon brush bodies are disposed on front and back ends of the thin bottom plate; the plurality of isolated convex sleeves for fastening pieces are respectively arranged on two sides of the isolated convex sleeves for front and back carbon brush bodies; a round installing through hole is disposed on the thin bottom plate between the isolated convex sleeves for front and back carbon brushes; and through holes are respectively disposed on front and back end faces of the isolated convex sleeves for front and back carbon brush bodies. The carbon brush sleeve for the DC motor uses the isolated convex sleeves for front and back carbon brush bodies and plural isolated convex sleeves for fastening pieces to isolate front and back carbon brushes and the metal fastening pieces, thus avoiding short circuit between the carbon brush lead-out wire and other parts (such as metal fastening pieces and etc.), and preventing the short circuit accident generated by accumulation of the carbon powders owing to intensive wearing on the carbon brush. The utility model has simple and reasonable structure, easy and convenient installation.
Description
Technical field
The utility model relates to the dc motor technology field, especially a kind of direct current machine carbon brush cover.
Background technology
In the existing direct current carbon brush electric machine structure, because carbon brush is outer dewiness, barrier assembly is not set between them, therefore, in carbon brush lead-out wire and process that the copper brace is connected, the carbon brush lead-out wire very easily is short-circuited with other parts (as: metal fastenings etc.), especially carbon brush in use for some time, carbon brush wearing and tearing aggravation, carbon dust gathers increase, also can cause short circuit easily.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of simple and reasonable for structure, can effectively prevent to gather the direct current machine that causes short circuit carbon brush cover because of carbon dust.
The purpose of this utility model is achieved in that
A kind of direct current machine carbon brush cover, the carbon brush cover is installed in the end face at carbon brush for electric machine place, it is characterized in that, described carbon brush cover is the tabular body of being made by insulating material of book, it comprises the book base plate, a plurality of securing members are isolated protruding cover and preceding, back carbon brush body is isolated protruding cover, before, back carbon brush body isolate protruding be set on the book base plate before, back two ends, a plurality of securing members are isolated before protruding cover branch is located at, back carbon brush body is isolated the both sides of protruding cover, preceding, back carbon brush is isolated on the book base plate between the protruding cover and is also had the circular mounting through hole, and before described, back carbon brush body is isolated on the front/rear end of protruding cover and is had through hole, so that it is when the carbon brush cover is installed in carbon brush for electric machine place end face, preceding, back carbon brush body isolate protruding cover and each securing member isolate protruding cover can be with carbon brush for electric machine and securing member isolation; This kind of direct current machine carbon brush cover, by the carbon brush cover is installed on the end face of carbon brush for electric machine place, utilize forward and backward carbon brush body to isolate protruding cover and a plurality of securing member is isolated protruding cover, forward and backward carbon brush and metal fastenings are kept apart, both can avoid carbon brush lead-out wire and other parts (as: metal fastenings etc.) to be short-circuited, also can overcome because of carbon brush wearing and tearing aggravation, carbon dust gathers increase, and causes the accident of short circuit; Total is simple, reasonable, installs simple and easy, convenient.
The purpose of this utility model can also adopt following technical measures to solve:
The quadripolar corners position of described book base plate is provided with securing member and isolates protruding cover, with the metal fastenings at place, four jiaos of positions of supporting carbon brush place end face.
Described forward and backward carbon brush body is isolated the top of protruding cover for the sealing shape, to improve its isolating seal.
As the scheme of more optimizing, also be provided with thermostat mounting groove position on the book base plate of described carbon brush cover, thermostat can directly be fixed on this mounting groove position by this mounting groove position, has both made things convenient for the installation of thermostat, makes the syndeton between them compacter, reasonable again.
As scheme more specifically, it is cylindrical trepanning on the carbon brush cover book base plate that described securing member is isolated protruding cover.
The beneficial effects of the utility model are:
(1) direct current machine of the present utility model carbon brush cover, by the carbon brush cover is installed on the end face of carbon brush for electric machine place, utilize forward and backward carbon brush body to isolate protruding cover and a plurality of securing member is isolated protruding cover, forward and backward carbon brush and metal fastenings are kept apart, both can avoid carbon brush lead-out wire and other parts (as: metal fastenings etc.) to be short-circuited, also can overcome because of carbon brush wearing and tearing aggravation, carbon dust gathers increase, and causes the accident of short circuit; Total is simple, reasonable, installs simple and easy, convenient;
(2) this kind of direct current machine carbon brush cover, also by on the book base plate of carbon brush cover, setting up thermostat mounting groove position, thermostat can directly be fixed on this mounting groove position by this mounting groove position, has both made things convenient for the installation of thermostat, makes the syndeton between them compacter, reasonable again.
