Abstract
The utility model relates to a flexible extraction line device with an equalizing ball, which is characterize in that a steel sleeve is connected with an insulation cylinder and a gasket; the external periphery of the steel sleeve is connected with a nut, a fastening nut and a nut clip; the fastening nut is connected with an equalizing ball; an external wiring joint is connected with an extraction line joint which is connected with an extraction line; the external wiring joint is connected with the hold-down nut and a spring washer. The flexible extraction line device has the advantages that 1. The wiring is tight and reliable and is hard to loosen; 2. The device is good in sealing effect and can bear higher pressure; 3. The structure is compact and needs very little inner operational space; 4. The device is convenient in installation and operation; 5. The electric insulation property is good; 6. The amount of partial discharging is small; 7. The device is a whole solid structure and no oil or gas or pressure is produced in the device; 8. Main parts are all made of high strength materials and are not easily damaged.
Description
Technical field
The utility model relates to a kind of band flexible out line device, particularly a kind of flexible out line device with voltage equalizing ball.
Background technology
Its high voltage pinout connector of the High-Voltage Electrical Appliances of some special construction not only requires electrical insulation capability good, partial discharge quantity is little, and need flexible out line, its joint requires the tight of card, contact resistance is little, arcing and discharge can not occur, 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 Outgoing Line Unit 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 200 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 utility model provides a kind of flexible out line device with voltage equalizing ball, its compact conformation, and good seal performance, office puts little, can not explode, and is not fragile.
The utility model is achieved like this, it comprises pinout connector, insulating cylinder, steel bushing, voltage equalizing ball, nut, binding nut, external compression nut, external the end of a thread, it is characterized in that steel bushing connects insulating cylinder and sealing gasket, the neighboring attaching nut of steel bushing, binding nut and clamp nut, connect voltage equalizing ball on binding nut, pinout connector connects external the end of a thread, and external the end of a thread connects clamp nut and spring washer.
The utility model has the advantages that: 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,, 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. 3, 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 4, 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; 5, 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; 6, because the device outside has voltage equalizing ball, so partial discharge quantity is little; 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.
