Abstract
The utility model relates to an end portion phase-to-phase insulation part, which comprises a phase insulator (A) and a phase insulator (B) which are independently moulded, and at least two intermediate linking rods, wherein the phase insulator (A) and the phase insulator (B) are respectively fixed to two ends of the intermediate linking rods in an ultrasonic welding method. As a result, used raw material amount can be substantially reduced, and at the same time manufacturing cost of punch dies is reduced, the structure is relatively simple and is easy to process, service life of the punch dies is effectively prolonged, toughness of the intermediate linking rods is improved, so that the end portion phase-to-phase insulation part is easy to operate and use, and work efficiency on a motor production line is improved.
Description
[technical field]
The utility model belongs to end phase insulation technical field, relates in particular to a kind of end interphase insulating member that is applied on the motor.
[background technology]
Because air-conditioning and refrigerator compressor motor are to work in the refrigerant and refrigerator oil mixture operating mode of airtight, high pressure, high temperature, insulation property to motor require very high, and between the out of phase enamelled wire in motor end, exist higher voltage poor, for guaranteeing the not insulation property of lead between the homophase, requirement is injected insulation and is used polyester film between the alternate enamelled wire of motor both side ends, be referred to as the end phase insulation.Be the manufacturability of guaranteeing that the alternate enamelled wire in motor both ends effectively separates and produces, the end phase insulation is designed to: the A of insulation mutually at both ends, the B that insulate mutually, and in the middle of connect bar three partly.For guaranteeing the alternate enamelled wire of effective spaced end, the distance between A, B of should guaranteeing to insulate mutually, this distance are generally the folded thick 10mm of adding of electric machine iron core.
But there is the shortcoming of three aspects in present existing traditional phase insulation:
(1) part is formed by the disposable blanking of unitary piece of material, and wherein most material is wasted;
(2) it is thinner to connect bar in the middle of, and poor rigidity causes on the motor production line operating efficiency low;
(3) the part area is big, and form die also must be bigger, and the middle bar that connects is narrow and grow, and the punch die manufacture difficulty is big, cost is high.
[utility model content]
In order to solve the above-mentioned technical problem that exists in the prior art, the utility model provides a kind of raw material consumption few, punch die structure is simple relatively, be easy to processing, and punch die low cost of manufacture, life-span are long, the end interphase insulating member of easy operating use simultaneously.
The technical scheme that the prior art problem that solves the utility model adopts is:
A kind of end interphase insulating member includes the A of insulation mutually of independent moulding respectively, the coupling bars in the middle of B and at least two that insulate mutually, and described insulate mutually A and the B that insulate mutually are separately fixed at the two ends of described centre coupling bar by the ultrasonic bonding mode.
Further, the described A that insulate mutually forms by independent blanking on insulating material with the B that insulate mutually, and described middle coupling bar is to adopt high-strength PET ultimate fibre coiled material, and plants to cut and form by heating alignment, fixed length.
Further, described middle coupling bar has 2 to 8.
Further, the diameter of described middle coupling bar is for to be defined as 0.7mm～1.0mm according to arts demand.
The beneficial effects of the utility model:
The utility model technique scheme, can save the raw material consumption significantly, reduce the manufacturing cost of punch die simultaneously, structure is simple relatively, be easy to processing, effectively prolong Life of Punch Die, and improved the rigidity of middle coupling bar, and make the end interphase insulating member be easier to operation and use, improve operating efficiency on the motor production line.
[description of drawings]
Fig. 1 is the structural representation of a kind of end interphase insulating member embodiment described in the utility model.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in fig. 1:
The utility model provides a kind of end interphase insulating member, includes the A1 of insulation mutually of independent moulding respectively, insulate B2 and middle coupling bar 3 mutually; Wherein, the described A1 that insulate mutually forms by independent blanking on insulating material with the B2 that insulate mutually, coupling bar 3 has two in the middle of described, diameter is about 0.9mm, all adopt the high-strength PET ultimate fibre, and plant to cut and form by heating alignment, fixed length, and described insulate mutually A1 and the B2 that insulate mutually are separately fixed at the two ends of centre coupling bar 3 by the ultrasonic bonding mode.
Certainly, described in the middle of coupling bar 3 also can 2～8, its diameter can be defined as 0.7mm～1.0mm according to arts demand.
Like this, can save the raw material consumption significantly, reduce the manufacturing cost of punch die simultaneously, structure is simple relatively, be easy to processing, effectively prolong Life of Punch Die, and improved the rigidity of middle coupling bar 3, and make the end interphase insulating member be easier to operation and use, improve operating efficiency on the motor production line.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
