Abstract

A leading-out method for a brushless direct current motor outgoing lines for an electric compressor is characterized in that three-phase winding enameled wires of a brushless direct current motor extend out of a motor and directly serve as the outgoing lines, insulating sleeves are sleeved on the outgoing lines, the suspension end of every phase enameled wire is welded to a wire connecting piece after a paint layer at the suspension end of every phase enameled wire is removed, and simultaneously an opening of the edge of a wire connecting piece base wraps pipe openings of the insulating sleeves to enable the outgoing lines to be located. According to the method, end dimensions of the ends of the motor outgoing lines can be reduced, resistance of an outgoing line cable welding link is eliminated, outgoing line cable faults are avoided, reliability of the brushless direct current motor stator outgoing lines is improved, and material cost and labor cost are reduced.

Description

DC brushless motor lead-out wire outbound course for motor compressor

Technical field

The present invention relates to a kind of motor technology, especially a kind of mode of connection of motor winding leading-out wire, specifically DC brushless motor lead-out wire outbound course for a kind of motor compressor.

Background technology

As everyone knows, the motor winding must be received in socket by corresponding lead cable, and an end of lead cable must be connected with motor winding welding, the other end inserts in the plug that connects control box by lug plate, and because there is enamelled coating on the motor winding enamelled wire surface, if deal with improperly, can cause contact resistance to increase, produce rosin joint etc.And the solder joint place easily fractures or sealing-off, simultaneously, because the size of solder joint is greater than the size of lead cable, also want additional insulating sleeve, can cause the motor lead-out wire end thick, occupy the problem that space increases, these have not only increased the workload of motor lead-out wire, increase manufacturing cost, and stayed potential safety hazard.

Summary of the invention

The objective of the invention is to connect workload for existing motor winding leading-out wire large, easily produce the problems such as rosin joint, invent DC brushless motor lead-out wire outbound course for a kind of motor compressor.

Technical scheme of the present invention is:

DC brushless motor lead-out wire outbound course for a kind of motor compressor, it is characterized in that three phase winding enamelled wires of DC brushless motor are extended and stretch out outside motor, and using it directly as lead-out wire, put insulating sleeve on lead-out wire, then the removing of the enamelled coating on the free end of each phase enamelled wire is rear and lug plate is weldingly connected, and the opening at wiring bar edge is encased to the insulating sleeve mouth of pipe simultaneously and makes its location.

Described insulating sleeve is the Teflon pipe.

Described insulating sleeve is by color or stick on sign and distinguish the three-phase outlet.

Described enamelled wire extends the length of stretching out motor and should match with its distance to connector socket.

Beneficial effect of the present invention:

Because motor compressor uses thicker, the every circle radical of the single wire diameter of DC brushless motor winding also more, after removing the motor lead-out wire cable, the enamelled wire of winding coil goes out line strength and enough bears its weight, and the motor sealing immediately after motor compressor of packing into, can often not be disassembled; The Furtulon sleeve pipe has excellent dielectric property and resistance to chemical attack, high temperature resistant, high pressure resistant, do not absorb water, non-conductive, coefficient of friction is low and the performance such as not aging.So, cancel motor three-phase lead cable, not only can not affect the reliability of motor lead-out wire, can improve its functional reliability on the contrary, reduce the generation of rosin joint phenomenon, greatly reduce contact resistance.

The present invention is due to after removing motor three-phase lead cable, each three of insulating sleeves that also saved the solder joint of each phase cable and solder joint place, thereby can reduce the end size of motor lead-out wire end, the resistance of elimination lead cable welding link, and avoid occurring this factor of lead cable fault, thereby more improved the reliability of DC. brushless electric machine stator lead-out wire, reduced material cost and labour cost.

Embodiment

Below in conjunction with drawings and Examples, the present invention is further illustrated.

As Figure 1-3.

DC brushless motor lead-out wire outbound course for a kind of motor compressor, at first, cancel motor three-phase lead cable, three phase windings (2) enamelled wire of DC brushless motor is directly extended and stretches out outside the motor winding, and using it directly as lead-out wire, putting three kinds on lead-out wire or not the teflon insulating sleeve of color or puts the teflon insulating sleeve of same color but distinguished by sign, then the removing of the enamelled coating on the free end of each phase enamelled wire (identical with existing sweep-out method) is rear and lug plate is weldingly connected, the opening at wiring bar edge is encased to the insulating sleeve mouth of pipe simultaneously and make its location, the opening at wiring bar edge will encase the Furtulon sleeve mouth of pipe, to guarantee that it covers enamelled wire fully, as Fig. 3.During concrete enforcement, enamelled wire extends the length of stretching out motor and should match with its distance to connector socket, as shown in Figure 1, 2.

The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
