Abstract
The invention relates to a polyimide coiled sleeve and a processing method thereof. The sleeve is formed by coiling multiple layers of polyimide films of which the single surfaces are coated with polytetrafluoroethylene, and shaping the coiled polyimide films at a high temperature. The processing method of the polyimide coiled sleeve comprises the following steps: coiling the multiple layers of polyimide films of which the single surfaces are coated with the polytetrafluoroethylene on a rod core with a certain diameter, adhering the polyimide films together through high-temperature processing and shaping, and taking out the rod core to form the coiled sleeve. The polyimide coiled sleeve and the processing method thereof are a protecting sleeve and a processing method thereof; the protecting sleeve is simple in structure and low in cost, is easy to manufacture, and is suitable to be used by a motor of a refrigeration compressor; the protecting sleeve is flexible and high-temperature-resistant; further, the wall of the sleeve is quite thin; the working environment of the motor of the refrigeration compressor can be borne; the use requirement is met; and the role of protecting a varnished wire and a wiring harness is achieved.
Description
Technical field
The present invention relates to motor enamelled wire outer tube field, especially polyimides coiling sleeve pipe and processing method thereof.
Background technology
Be to guarantee the fail safe of motor, a part of refrigeration compressor motor overlaps tubing on the enamelled wire between winding and the binding post, improving the insulation property of enamelled wire, and prevents that enamelled coating because of enamelled wire from damaging and causes winding to be scrapped even motor is scrapped.Simultaneously high-power refrigeration compressor motor requires the cover tubing in lead wire bundle outside, plays the protection wire harness and in processing and use, is not produced mechanical damages such as scraped finish damage.
At present the sleeve pipe of suit enamelled wire is glass braid sleeve pipe and two kinds of teflon sleeves, and wherein the glass braid sleeve pipe is that glass braid and dip-coating organosilicon coating form, and this sleeve pipe can not be in the use of the workplace of refrigeration compressor motor.The cost of teflon sleeve is high, and hardness is also high, and owing to the reason of material property can't be with the wall thickness reduction of sleeve pipe, so, though use its workplace that can be used in refrigeration compressor motor, consider all inconvenient from cost, serviceability aspect.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of reasonable in design, manufacture easy, easy to use, tube wall thin and soft durable polyimides coiling sleeve pipe and processing method thereof.
The objective of the invention is to realize through following technological means:
A kind of polyimides coiling sleeve pipe is characterized in that: this sleeve pipe is to apply the multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe that high-temperature shaping forms with single face.
A kind of processing method of polyimides coiling sleeve pipe; It is characterized in that: the multilayer polyimide winding film that applies polytetrafluoroethylene with single face is on the excellent core of certain diameter; Adhesive property after utilizing polytetrafluoroethylene at high temperature happy and harmonious behind the coiling and polyimides at high temperature still can keep the characteristic of dimensionally stable; Typing bonds together polyimide film through high temperature process, takes out excellent core and promptly forms the coiling sleeve pipe.
Advantage of the present invention and good effect are:
1, this protective casing is to apply the multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe that high-temperature shaping forms with single face; Because polyimides has good physical and mechanical properties; Therefore this sleeve pipe has good physical and mechanical properties equally; Can tolerate mechanical damages such as scraped finish, play the effect of protective paint envelope curve and wire harness.
2, owing to the employed polytetrafluoroethylene of this protective casing, polyimide film all are the materials that is applicable to that refrigerant compressor uses, so this sleeve pipe can bear the operational environment of refrigeration compressor motor.In addition, owing to polyimides can steady in a long-term be worked under 200 ℃ condition, so this sleeve pipe can reach the instructions for use of 180 ℃ (H) level motor.
3, this protective casing can be controlled at wall thickness below the 0.25mm, so whole sleeve pipe is very soft, is highly suitable in the narrow and small motor of installing space and uses.
4, this protective casing processing method simple and flexible can be adjusted the internal diameter of this sleeve pipe according to the difference of product applicable situation, thereby make this sleeve pipe both can be used for the winding protection of refrigeration compressor motor, also can be used for wire harness protection.
5, the present invention be a kind of simple in structure, easy to manufacture, cost is low, be fit to protective casing and processing method thereof that refrigeration compressor motor uses; This protective casing is soft, high temperature resistant and tube wall is very thin; Can bear the operational environment of refrigeration compressor motor; Satisfy instructions for use, play the effect of protective paint envelope curve and wire harness.

Embodiment
Be described in detail embodiments of the invention below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of polyimides coiling sleeve pipe, this sleeve pipe are to apply the multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe 1 that high-temperature shaping forms with single face.
The processing method of this polyimides coiling sleeve pipe is: the multilayer polyimide winding film that applies polytetrafluoroethylene with single face is on the excellent core of certain diameter; Adhesive property after utilizing polytetrafluoroethylene at high temperature happy and harmonious behind the coiling and polyimides at high temperature still can keep the characteristic of dimensionally stable; Typing bonds together polyimide film through high temperature process, takes out excellent core and promptly forms the coiling sleeve pipe.
Claims (2)
1. polyimides coiling sleeve pipe is characterized in that: this sleeve pipe is to apply the multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe that high-temperature shaping forms with single face.
