Abstract
A kind of flexible out line device, it is characterized in that steel bushing connects insulating cylinder and sealing gasket, the neighboring attaching nut of steel bushing, binding nut and nut clamp connect the external compression nut on the nut clamp, pinout connector connects external the end of a thread, and external the end of a thread connects external compression nut and spring washer.Its advantage is: 1, wiring is fastening reliable; 2, good sealing effect; 3, positive and negative two kinds of screw threads are arranged on the steel bushing respectively, nut can not produce loosening, thereby has guaranteed sealing effectiveness; 4, compact conformation, required built-in function space is very little; 5, easy to install; 6, electrical insulation capability is good; 7, device is the total solids structure, and the no gas of self inner nothing oil does not have pressure; 8, critical piece is high-strength material and makes, and is not fragile.
Description
Technical field
The present invention relates to a kind of flexible out line device, particularly a kind of High-Voltage Electrical Appliances flexible out line device.
Background technology
Its high voltage pinout connector of the High-Voltage Electrical Appliances of some special construction not only requires electrical insulation capability good, and need flexible out line, its joint requires the tight of card, contact resistance is little, arcing and discharge can not appear, the structure of this electric appliances is very compact in addition, the lead-in wire space that can provide very little (generally having only 10～50 millimeters).It will adopt is overcoat porcelain bushing (or silica gel sleeve pipe etc.) and sealing device and existing flexible out line is main.This type of Outgoing Line Unit all needs bigger rising seat or inner bigger operating space and the insulating space (according to the space of different electric pressure needs more than at least 100 millimeters) of needing.Because the size of these structures is all very big, therefore need extraordinary Sealing Technology and installing space, this needs the occasion of cramped construction just can't use at some.
Summary of the invention
The purpose of this invention is to provide a kind of flexible out line device, its compact conformation, good seal performance can not exploded, and is not fragile.
The present invention is achieved like this, it comprises flexible out line, pinout connector, insulating cylinder, steel bushing, briquetting, nut, binding nut, nut clamp, external compression nut, external the end of a thread, it is characterized in that steel bushing is fixed on the High-Voltage Electrical Appliances insulating cylinder with briquetting, nut, binding nut successively, as required respectively in High-Voltage Electrical Appliances insulating cylinder inboard, the outside places sealing ring.The pinout connector that connects flexible out line is connected on external the end of a thread with engage thread, and external the end of a thread is fixed on the steel bushing by external compression nut and spring washer, sealing ring and seals.Between binding nut and external compression nut, carry out interlocking with the nut clamp,
Advantage of the present invention is: 1, adopt between inner flexible lead-out wire and pinout connector to be threaded.Therefore the joint resistance of getting an electric shock indirectly is little, and wiring is fastening reliable, can not produce loosening; 2, positive and negative two kinds of screw threads are arranged on the steel bushing respectively, this structure makes binding nut and external compression nut reach interlocking by the nut clamp, thus nut can not produce loosening, thereby guaranteed sealing effectiveness; 3,, and adopted hermetically-sealed construction efficiently because device self size is little, so good sealing effect, the higher external and internal pressure that can bear between the electrical equipment and the external world is poor. 4, this apparatus structure compactness, inside adopt the copper braid over braid to do flexible out line, and therefore required built-in function space is very little, and general need spacing get final product more than 15 millimeters; The mounting means that 5, many clocks can be arranged according to the concrete inner needs of electrical equipment, it is comparatively convenient to install and use, and applicability is wider; 6, according to actual conditions, steel bushing not only can adopt insulating material such as external application epoxy resin also can directly adopt glass-reinforced plastic material to make steel bushing, and the electrical insulation capability of this sampling device is better; 7, device is the total solids structure, and the no gas of self inner nothing oil does not have pressure, therefore installs and self does not have blast, leaks; 8, critical piece is metal material and high-strength insulating material is made, and is therefore not fragile, also is not easy to ftracture, phenomenon such as fragmentation.
