Abstract
The utility model discloses a special terminal installation device of direct current motor, including motor housing and terminal screw, the terminal screw passes motor housing and the seam welding of motor inner weld, and the casing is equipped with the casing square hole, and the terminal screw is equipped with the core connecting portion with casing square hole assorted side, on the terminal screw and also threaded connection have and be used for the gland nut on motor housing with terminal screw fixed connection. The utility model discloses an insulating cover of special terminal screw and special square hole is connected, can stop the screw swivelling movement when making the screw wiring fixed, and security, reliability are stronger.
Description
Technical field
This utility model is related to technical field of motors, particularly to a kind of direct current generator Special wiring post erecting device.
Background technology
Existing motor binding post is fixedly connected with casing circular hole using standard screws, and screw wiring connects easy when screwing
Cause screw in rotary moving, thus motor internal connecting line sealing-off can be caused, cause motor internal short-circuit or breaking.
Content of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of direct current generator Special wiring post to install
Device, this device adopts Special wiring post screw and special square hole insulation sleeve to connect, and makes screw wiring can prevent screw when fixing
In rotary moving, safety, reliability are higher.
For solving the above problems, this utility model provides technical scheme below：
A kind of direct current generator Special wiring post erecting device, including motor housing and binding post screw, binding post screw is worn
Cross motor housing and weld wire bonding with motor internal, casing is provided with casing square hole, and binding post screw is provided with and casing square hole phase
The square core connecting portion joined, binding post screw is also threaded with for being fixedly connected on binding post screw on motor housing
Clamp nut.
Wherein, binding post screw is arranged with the insulating washer with the cooperation of motor housing inwall.Further, binding post spiral shell
Nail on the square hole insulation sleeve being arranged with the casing square hole cooperation of motor housing.
Compared with prior art the beneficial effects of the utility model：
Binding post screw is first welded by direct current generator Special wiring post erecting device described in the utility model with motor internal
Wiring is welded, then insulating washer is inserted on binding post screw, and then binding post screw passes through the casing square hole of motor housing,
And so that the square core connecting portion of binding post screw and casing square hole is coordinated, then the Fang Xin that square hole insulation sleeve is inserted in binding post screw connects
Clamp nut is finally screwed in binding post screw so that binding post screw by socket part, and make square hole insulation sleeve put in casing square hole
It is fixedly connected with motor housing.This utility model by the casing square hole of motor housing, the square core connecting portion of binding post screw and
The square opening of square hole insulation sleeve coordinates so that binding post screw is when screwing clamp nut, and binding post screw will not concomitant rotation
Mobile, thus avoiding motor internal and binding post mode connects for screw the phenomenon such as distort, twist off, eliminate motor hidden danger, its structure is more
Firm, using safer.

Specific embodiment
With reference to Figure of description and embodiment, this utility model is described in detail：
Reference picture 1-3, a kind of direct current generator Special wiring post erecting device, including motor housing and binding post screw 4, connect
Terminal screw 4 is welded through motor housing with motor internal sealing wire 6, and casing is provided with casing square hole 5, and binding post screw 4 is provided with
The square core connecting portion 7 being matched with casing square hole 5, binding post screw 4 is also threaded with for binding post screw 4 is fixing
It is connected to the clamp nut 1 on motor housing.Insulating washer 3 with the cooperation of motor housing inwall is arranged with binding post screw 4.
Square hole insulation sleeve 2 with casing square hole 5 cooperation of motor housing is arranged with binding post screw 4.
During assembling, first binding post screw 4 is welded with motor internal sealing wire 6, then insulating washer 3 is inserted in binding post spiral shell
On nail 4, then binding post screw 4 is passed through the casing square hole 5 of motor housing, and make the square core connecting portion 7 of binding post screw 4 with
Casing square hole 5 coordinates, then square hole insulation sleeve 2 is inserted in the square core connecting portion 7 of binding post screw 4, and so that square hole insulation sleeve 2 is put into
In casing square hole 5, finally clamp nut 1 is screwed in binding post screw 4 so that binding post screw 4 is fixedly connected with motor housing.
This direct current generator Special wiring post erecting device passes through the casing square hole 5 of motor housing, the Fang Xin of binding post screw 4
The square opening of connecting portion 7 and square hole insulation sleeve 2 coordinates so that binding post screw 4 is when screwing clamp nut 1, binding post screw 4
Will not moving concomitant rotation, thus avoiding motor internal the phenomenon such as be connected distortion with binding post screw 4, twist off, eliminating motor
Hidden danger, its structure is more firm, using safer.
The above, be only preferred embodiment of the present utility model, not technical scope of the present utility model is made
Go out any restriction, thus every any trickle amendment above example made according to technical spirit of the present utility model, equivalent
Change and modification, all still fall within the range of the technical solution of the utility model.
