Abstract

The utility model discloses a connecting structure for aluminium enamelled wires and copper wires in aluminum-core winding motors, which comprises aluminium enamelled wire winded on the motor stator and leading copper wire in joint portion of the motor, ends of the copper wire and the aluminium enamelled wire are synchronously pressed on a connector with tinning layer inside. The connecting structure of the utility model connects the leading copper wire and the aluminium enamelled wire in joint portion of the aluminum-core winding motor by employing the inner-tinned connector, electric corrosion can be reduced during utilizing process for metal activity of the tin is between the copper and the aluminium; which improves service life and quality of the aluminum-core winding motor; tinning technique is relatively simple in processing techniques. Fastening teeth are provided inside the connector, firstly, connection strength of the copper wire and the aluminium enamelled wire can be reinforced, secondly, a pincers clamping connector can be employed without stripping insulation paint on the aluminium enamelled wire, which reduces connection procedures and lowers production cost.

Description

The syndeton of aluminium enamel-covered wire and copper cash in the aluminium core winding motor
Technical field
The utility model relates to a kind of aluminium core winding motor, the syndeton of aluminium enamel-covered wire and copper cash in particularly a kind of aluminium core winding motor.
Background technology
For reducing the motor production cost, replace the motor of copper cash to begin gradually to promote with aluminum steel at present, stator winding commonly used is an aluminium enamel-covered wire, electric machine joint part lead-out wire is a copper cash.When directly connecting because of copper, aluminum conductor, the contact-making surface of these two kinds of metals very easily forms electrolyte with under the effect of airborne moisture, carbon dioxide and other impurity, thereby form with aluminium is that negative pole, copper are anodal primary cell, make aluminium produce couple corrosion, cause the contact resistance of copper, aluminium junction to increase.In addition,, be in operation after cold cycling (energising and outage) repeatedly, can make the contact point place produce bigger gap and influence contact, further increased contact resistance because the modulus of elasticity and the thermal coefficient of expansion of copper, aluminium differ greatly.The increase of contact resistance, motor are in operation connecting portion will the temperature rising.Corrosion oxidation will aggravate under the high temperature, produces vicious circle, and quality of connection is further worsened, and causes the contact point temperature too high even accident such as can smolder, burn at last, influences the quality and the useful life of aluminium core winding motor.
Summary of the invention
The technical problems to be solved in the utility model is: provide the syndeton of aluminium enamel-covered wire and copper cash in a kind of aluminium core winding motor that reduces aluminum steel and copper cash tie point generation galvano-cautery, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: the syndeton of aluminium enamel-covered wire and copper cash in a kind of aluminium core winding motor, what it comprised the aluminium enamel-covered wire 2 that is wrapped on the motor stator and motor blank area draws copper cash 3, is characterized in: have on the connector 5 of tin coating 4 in the end of drawing copper cash 3 and aluminium enamel-covered wire 2 is crimped on simultaneously.
The syndeton of aluminium enamel-covered wire and copper cash is to be provided with latch 6 in connector 5 in the above-mentioned aluminium core winding motor.
The syndeton of aluminium enamel-covered wire and copper cash is also to be with pyrocondensation pipe box 1 on connector 5 in the above-mentioned aluminium core winding motor.
Compared with prior art, the utility model is drawn copper cash and aluminium enamel-covered wire by what adopt that inner zinc-plated connector connects aluminium core winding motor blank area, because of the metal activity of tin between copper and aluminium, so in use just can reduce the generation of galvano-cautery phenomenon; Improve the useful life and the quality of aluminium core winding motor; And tin plating technique is simple relatively in processing technology.The inner latch first that is provided with of connector can be strengthened the bonding strength of copper cash and aluminium enamel-covered wire, and second need not divest the insulating varnish on the aluminium enamel-covered wire specially when adopting pliers to clamp connector, reduces to connect operation, lowers production cost.Be connected the pyrocondensation pipe box on the connector, first can prevent electric leakage, reduces potential safety hazard, and second can reduce contacting of water in air steam and carbon dioxide etc. and linkage section aluminum steel, can further reduce the generation of galvano-cautery phenomenon.Therefore this practicality has the excellent popularization value and use value.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: structure of the present utility model as shown in Figure 1, aluminium core winding motor is wrapped in that enamelled wire is an aluminium enamel-covered wire 2 on the motor stator, the lead of drawing of aluminium core winding motor blank area is a copper cash 3, be the galvano-cautery after reducing aluminum steel and copper cash being connected, now adopt copper to connect device 5, be provided with latch 6 in connector 5 inside, and crossed tin coating 4 in the inside of connector 5, at the aluminium enamel-covered wire 2 that connects aluminium core winding motor with when drawing copper cash 3, insert simultaneously in the connector 5 with the end of aluminium enamel-covered wire 2 drawing copper cash 3, pinch connector 5 flat by pliers then, the latch 6 of connection 5 inside will be abolished the insulating varnish on the aluminium enamel-covered wire 3 like this, and copper cash 3 and aluminium enamel-covered wire 2 are interconnected.Simultaneously for preventing electric leakage, water vapour in the air-isolation and carbon dioxide etc. contact with depainting section aluminum steel, exposed portion can carry out conventional insulation processing at aluminium enamel-covered wire 2 and the electric wire of drawing copper cash 3, and reasonable is to make it be subjected to the pyrocondensation pipe box 1 with insulation property of thermal contraction in aluminium enamel-covered wire 2 and the electric wire exposed part socket of drawing copper cash 3 by firing equipments such as hair dryer, baking oven, pyrocondensation machines.
