Description

A kind of connecting line construction of motor rectification module and pole coil

Technical field

The utility model is related to motor accessories field, the line knot of especially a kind of motor rectification module and pole coil Structure.

Background technology

In recent years, with the rise of international market diesel rail motor car, the auxiliary generator as one of diesel rail motor car core component Good opportunity to develop is welcome.Wherein, brushless auxiliary generator has the advantages that brush motor, while eliminating brush, cunning again Ring structure so that maintenance is simpler, and application prospect is more preferable.The rectification module of existing brushless motor and the line master of pole coil To use the copper strap wire of L-type after insulation processing be made, concrete structure can refer to Fig. 1,1 both ends ' of copper strap wire respectively with rectification mould The lead of block and pole coil is connected together（It is weldingly connected with pole coil, is connected by bolt presses with rectification module）, 1 ' of copper strap wire is fixed on steel dog with 2 ' of band in the bending part of 1 ' of copper strap wire.Since rectification module is unable to dipping lacquer processing, It needs to fix 3 ' blocks instead of rectification module using technique before dipping lacquer, backs out 4 ' of fixing bolt later, it is removed into reality from side Now dismantle.Existing general rectification module can draw an independent connection copper sheet outward, and be furnished with 5 ' of fastening bolt, 5 ' of fastening bolt Detachably, 1 ' of copper strap wire is pressed in the surface of connection copper sheet by 5 ' of fastening bolt, to realize 1 ' of copper strap wire and rectification mould The connection of block.When dismantling module in existing structure, since copper strap wire blocks rectification module fixing screws, need copper strap wire It tilts and bending could realize dismounting, this process causes to damage to the copper strap wire and band that have been cured, when reinstalling, and needs Copper strap wire is turned back reset condition, the damage again of copper strap wire is caused, fracture, the burn of bending part is easily led to, influences motor Normal operation；Oscillation phenomenon is easy tod produce when rotor high speed rotation, band is easy failure, loses to copper strap wire under vibrating conditions Fixed constraint；L-type insulated copper flat wire is in axial direction without fixation so that copper strap wire cannot be resisted during rotor runs at high speed , there is the hidden danger being easily broken off in impact caused by generated vibration and frequent start-stop.

Specific implementation mode

Referring to figs. 1 to Figure 10, the connecting line construction of a kind of the motor rectification module and pole coil of the utility model, including L The copper strap wire 1 of type, the copper strap wire 1 are made of axial direction part 11 and radial section 12, the end of the axial direction part 11 and radial section 12 It is connected respectively with rectification module and pole coil, the surface of the radial section 12 is provided with axial restraint pressing plate 2, the axial direction part 11 surface is provided with radially fixed pressing plate 3, and the position that the axial direction part 11 corresponds to rectification module fixing screws is provided with via 13.When installation, axial restraint pressing plate 2 can realize that the axial restraint of copper strap wire 1, radially fixed pressing plate 3 can realize the diameter of copper strap wire 1 To fixation, copper strap wire 1 can be made more to be firmly fixed on motor in this way；So-called via 13 is exactly that diameter is more than installation rectification The diameter of module fixing bolt used tool when dismounting rectification module, allen wrench can be used to pass through via 13 to fixed spiral shell Bolt is dismantled.

As a kind of preferred structure of axial restraint pressing plate 2, the axial restraint pressing plate 2 is by being located at both ends and being fixed on electricity Fixed part 21 on machine and the composition of holding section 22 positioned at centre, the holding section 22 is axially projecting to house copper strap wire 1 to be formed Space.Specifically, being provided with unthreaded hole on the fixed part 21, axial restraint pressing plate 2 is bolted on motor.

As a kind of preferred structure of radially fixed pressing plate 3, pedestal of the radially fixed pressing plate 3 by being fixed on motor 31 and cover board 32 form, the cover board 32 and pedestal 31 are detachably connected and mating surface is formed with the through-hole of accommodating copper strap wire 1.It is logical Cover board 32 and the cooperation of pedestal 31 are crossed to realize the radially fixed of copper strap wire 1.Preferably, the upper surface of the pedestal 31 is provided with appearance The groove 311 of copper strap wire 1 is set, the middle part of the cover board 32 is axially disposed symmetrical two inner fovea parts 321, the copper strap wire 1 in the inner fovea part 321.Because the space in rectification module and pole coil junction is few, it is arranged two Symmetrical inner fovea part 321, copper strap wire 1 is inlaid in inner fovea part 321, can be effectively reduced occupied by 3 axial direction of radially fixed pressing plate Space.

Preferably, the axial direction part 11 corresponds to the part of radially fixed pressing plate 3 and is set as radially inward recess portion 111.Cause The installation space for leaving copper strap wire 1 between rectification module and pole coil is less, if copper strap wire 1 is set as most conventional L-type, the case where causing to interfere with each other in the radial pressing plate of installation and axial restraint pressing plate 2, so in the axial direction part of copper strap wire 1 There are one recess portion 111, the installation of pressing plate 3 radially fixed in this way and axial restraint pressing plate 2 can be avoided mutually, avoid installing for 11 settings Interference.

Further, the axial direction part 11 is provided with the part of via 13 protrusion is set from inside to outside in 11 place plane of axial direction part It is equipped with the arc panel wing 14.The setting of the arc panel wing 14 is intended to make the width at 13 position of via, and other positions are all identical with copper strap wire 1, Even if the current-carrying cross section at via 13 is consistent at non-via 13, on the one hand ensure that current density is constant, has on the other hand also increased The intensity at 1 via 13 of copper strap wire is added.

The above concrete structure and dimension data are illustrated to the preferred embodiment of the utility model, but this reality It is not limited to the embodiment with novel creation, those skilled in the art are in the premise without prejudice to the spirit of the present invention Various equivalent variations or replacement can be also made down, these equivalent deformations or replacement are all contained in the application claim and are limited In fixed range.
