Abstract

The utility model discloses a flexible connection cable for a traction motor, which adopts a silicon rubber flexible cable used as a main body. The bare copper cores of both ends of the main body are pressed with terminals, and a soft flexible cable is formed. The utility model has the advantages that the flexible connection cable for a traction motor adopts the flexible cable used as the main body. The flexible cable has a favorable insulation outer layer and electrical conductivity, and the flexibility and the elasticity of the flexible connection cable for a traction motor are added. The utility model can absorb the impact of the self jounce of a rail and a vehicle and the electromagnetic force of a motor winding to the flexible connection cable for a traction motor, and can reduce the destruction of various impacts to the flexible connection cable for a traction motor. The flexible connection cable for a traction motor has super strong shock resistance, and can reduce the proper resistance of the flexible connection cable for a traction motor. The flexible connection cable for a traction motor stops the burned phenomena caused by the heating of the flexible connection cable for a traction motor, and simplifies production processes.

Description

The soft on line of traction motor

The utility model belongs to a kind of connecting conducting wire, the soft on line of particularly a kind of traction motor that uses on combustion engine.

At present, the fault rate of the east wind 4ABC type locomotive traction motor ZQDR-410ABC that moves on the railway is 17%, wherein, draw the on line fault and account for 37% of whole motor fault, individual other up to 74%, therefore, draw the on line fault become the restriction safe train operation a major issue.At present, all to adopt thickness be that the copper strips of 5 millimeters or 5.6 millimeters is made to the on line of drawing of diesel locomotive traction motor, and the whole on line of drawing is a rigid construction, because its flexibility is too poor, thereby its shock proof poor performance.Field data shows that the vertical power acceleration of the driving wheel of locomotive at the gap place is about 15 times of acceleration due to gravity, and the power acceleration that passes to armature surface can reach 25 times of acceleration due to gravity.In addition, the electromagnetic force that motor winding produces also can cause certain shock and vibration to drawing on line, these two kinds of power act on the on line of drawing of traction motor coil simultaneously, have caused very big impact and vibration to drawing on line, and what this impact and vibration can make rigid construction draws on line generation brisement.In addition, because the space is narrow and small, complex-shaped in the electrical motor, thereby also more complicated of the shape of drawing on line, so the on line of drawing of electrical motor adopts the welding structure of abandoning usually, to realize required shape.But welding will inevitably cause contact resistance to increase, and the poor quality of the increase of contact resistance or welding, can make the weld heating again, the phenomenon of drawing on line appears blowing, and draw on line in case fracture, the vanishing suddenly of the main flux of series excitation traction motor causes the parking accident of electrical motor driving.Also have, the processing technology of drawing on line with the copper strips welding is more complicated also, the cost height, consumes greatly, and assembling is inconvenient, inefficiency.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, solves the rigidity copper strips and draws the problem that on line exists, provide a kind of good springiness, shock-resistant, cost is low, the soft on line of traction motor being convenient to assemble.

The utility model adopts the silaatic flexible cable as main body, is suppressed with connection terminal on the naked copper core at its two ends, constitutes flexible soft on line.

Advantage of the present utility model is:

1, adopt import silaatic flexible cable as the main body of drawing on line, not only has the outer and good electric conductivity of good insulation performance, and, the elasticity and the elasticity of drawing on line have been increased, this elasticity can absorb from track and locomotive self jolts and the electromagnetic force of motor winding to drawing the impact of on line, reduce various impacts greatly and drawn the destruction that on line is brought, had extremely strong shock resistance.

2, all be flexible cable between two connection terminals, and apply the coercive method connection terminal is fixed on the two ends of drawing on line, eliminated the big problem of welded structure contact resistance, and reduced to draw the resistance of on line itself, stopped because of drawing the phenomenon that the on line heating is burnt, production technology is further simplified, saved work time cost and corresponding apparatus, reduced productive costs.

3, the main body of drawing on line adopts flexible cable, has brought convenience to assembling, has improved work efficiency.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Embodiment 1:

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model adopts the silaatic flexible cable as main body, and described silaatic flexible cable is one, and it is made up of multiply multicore copper conductor 2 and silicon rubber insulation outer 3; Be suppressed with connection terminal 1 on the naked copper core at silaatic flexible cable two ends, on the connection terminal 1 mounting hole arranged, described connection terminal 1 is a copper pipe, after being installed on the naked copper core, be pressed into one again, and on naked copper core and connection terminal 1, ward off tin, to reduce its contact resistance, improve electric conductivity; Also have insulating barrier 4 on the naked copper core between connection terminal 1 and the silaatic flexible cable main body, insulating barrier 4 adopts single-coated foam to twine and makes, to improve the insulating power of flexible cable.

Embodiment 2:

As shown in Figure 5 and Figure 6, its structure such as embodiment 1, difference is that the silaatic flexible cable is two, is installed together side by side, to improve its elasticity, adapts to the needs of different structure.

Embodiment 3:

As shown in Figure 7 and Figure 8, its structure such as embodiment 2, difference is, long, weak point of two silaatic flexible cables, and the one end lumps together and is compressed on the connection terminal 5, and connection terminal 5 is a bending, so that install; The other end of silaatic flexible cable is compressed on respectively on two connection terminals 1, to adapt to the needs of different structure.

Embodiment 4:

As Fig. 9 and shown in Figure 10, its structure such as embodiment 1, difference is that the silaatic flexible cable is a quad, four multiply multicore conductors 2 that are arranged side by side is promptly arranged, to improve its capacity in insulating outer layer 3.
