The direct-insertion-type small flat cable head for the submersible motor comprises a small flat cable, and is characterized by consisting of a shell, sealing adhesive, a thin Teflon adhesive tape, a thick Teflon adhesive tape, a cushion block, a sealing gasket, a sheath-type flange pressing block and a plug, wherein the small flat cable is inserted into the input end of the shell and is sealed by the sealing adhesive; parallel subbodies in the small flat cable penetrate through the cushion block and the sealing gasket, are connected with the plug, and are enwrapped with the thin Teflon adhesive tape and the thick Teflon adhesive tape; the plug is put into the sheath-type flange pressing block; the parallel subbodies in the small flat cable are circumferentially positioned according to the cushion block; and the cushion block, the sealing gasket and the sheath-type flange pressing block are fixed in the shell. The direct-insertion-type small flat cable head for the submersible motor is strict in structure and high in insulating performance and leakage-resistant performance; products which can run reliably are provided for users at home and abroad, and particularly the products having the installation way are required in overground work in a cold winter; and the installation of the direct-insertion-type small flat cable head for the submersible motor is very convenient, time-saving and labor-saving.
Description
(1) technical field:
The invention belongs to petroleum machinery field, especially a kind of direct-insertion-type small flat cable head for submersible motor.
(2) background technology:
The important component part that the special direct insertion cable end of submersible electric machine with oil is oil extraction in oil field Electric Submersible Pump System is unique parts that electrical source of power is provided to down-hole submersible electric pump.It is arranged on submersible electric machine with oil head, and the fine or not direct relation of its various performances the useful life of Electric Submersible Pump Unit.The little flat cable of conventional submersible electric machine with oil was that wound form is installed in the past, on-the-spot installation is cumbersome, to from the little flat installing hole of motor head, pull out lead-in wire, with the plug in little flat cable to after connecting, carry out again insulation processing, seal each plug with insulating tape, again plug is sent back in the little flat hole of motor head after will carrying out insulation processing between three plugs, then by fastening connecting bolt good.This connected mode is very difficult in cold field work, and the material of sealing as insulation can become very hard, and poor flexibility, wastes time and energy, and increases again on-the-spot operating cost.And the little flat cable head of plug-in type of electrical machinery plant's getting up early exploitation, it is unreliable that user thinks that plug place connects, and often goes wrong.And versatility is poor, cannot dock with external motor, in oil field is complete, be used hardly.Therefore, the little flat cable head of straight plug-in type of development high reliability is important topic.
(3) summary of the invention:
The object of the present invention is to provide a kind of direct-insertion-type small flat cable head for submersible motor, it can solve the deficiencies in the prior art, it is a kind of special direct-insertion-type small flat cable head matching with plug-in type motor head, reliable connection when it can guarantee that cable docks with motor, reduce field operation time, connecting material and operating cost, increase work efficiency.
Technical scheme of the present invention: a kind of direct-insertion-type small flat cable head for submersible motor, comprise little flat cable, it is characterized in that it is made up of housing, fluid sealant, thin teflon adhesive tape, thick teflon adhesive tape, cushion block, sealing gasket, protective-cover type flange briquetting and plug; In the input of described little flat cable insertion housing and according to sealant sealing; Split side by side in described little flat cable is connected with plug through cushion block and sealing gasket respectively; Split side by side in described little flat cable is wrapped with thin teflon adhesive tape and thick teflon adhesive tape; Described plug is placed in protective-cover type flange briquetting; Split side by side in described little flat cable is circumferential registration according to cushion block; Described cushion block, sealing gasket and protective-cover type flange briquetting are fixed in housing; Described sealing gasket tightly depends on the split that is the little flat cable after circumferential registration and is sealing state.
Described cushion block, sealing gasket and protective-cover type flange briquetting are fixed in housing according to compressing locknut.
Between described protective-cover type flange briquetting and compression locknut, be provided with alignment pin and lead pad.
The output of described housing is fixedly connected with transportation cap.
The output of described housing is provided with transportation cap pad with the junction of transportation cap, and seals according to O RunddichtringO.
The output of described housing is fixedly connected with according to connecting bolt, bullet pad and nut with transportation cap.
What described plug was selected high reliability beryllium-bronze is electric-conductor.
Described protective-cover type flange briquetting is the briquetting that polyetheretherketonematerials materials is made.
Operation principle of the present invention: the design, from the inner structural members of small flat cable head of submersible motor, considers user's demand, first will guarantee the overcurrent area of conductive component in cable end; Carry out design of Sealing Structure, improve the temperature resistant grade of little flat cable head, what select high reliability beryllium-bronze is electric-conductor, the material insulation property of former little flat cable head internal flange briquetting meets the demands, but mechanical strength is poor, in assembling process, embrittlement phenomenon occurs often, as after going wrong, change also cumbersome, in new construction, the material of insulating part is exchanged as senior plastic material, the continuous serviceability temperature of this material is high, also there is high rigidity and hardness, and exclusive high-tensile and fatigue resistance; Its heat-resisting indeformable performance and chemical stability are all good in addition, and before temperature reaches 260 degree, this material all has fabulous dielectric property, and can resist energy-ray irradiation; For the rotation of peventing member in assembling, increase positioned internal pin; Consider the relative gap of conductive component, improve inner insulating part structure, adopt protective-cover type flange briquetting to be used for plug to carry out insulation protection, it has been that insulating effect has increased again the creepage distance between conductive component simultaneously, improve anti-electric creepage performance, made overall structure in use sturdy and durable safe and reliable; Housing is the supporter of structure as a whole; Cushion block is the supporter that converts circumferential registration for the side by side little flat cable of split to; Sealing gasket is for cable is sealed; O RunddichtringO and transportation cap pad seal in the middle of transportation.
Superiority of the present invention: 1, of a tightly knit structure, the insulating properties of the present invention and anti-electric creepage performance are high, for vast users at home and abroad provides reliable product, particularly in aboveground operation in cold winter, need especially the product of this mounting means; 2, the on-the-spot installation of the present invention is very convenient, time saving and energy saving, only little flat cable head directly need be inserted in the socket in the little flat hole of motor head and can complete mating operation, save the process of sealing insulating material loaded down with trivial details when the little flat cable head of wound form docks completely, connect fast, greatly reduce labour intensity, go into the well to install and won the more time for completing a whole set of Site for Unit of submersible electric pump, can be enterprise and client and bring better benefit.
