Abstract
The utility model relates to a vacuum on-off tube with a novel contact structure, which comprises a guide sleeve, an insulating outer shell, a moving-end component, a static-end component and a shielding barrel, wherein one end of the insulating outer shell is connected with a corrugated tube though a moving cover plate, and the other end is connected with the static-end component through a static cover plate; contacts of the moving-end component and the static-end component are opposite; a moving conducting rod and the moving cover plate are located by the guide sleeve; and the shielding barrel is directly connected with the insulating outer shell. The utility model is characterized in that a contact is made of integrated copper-chromium alloy, and is provided with six inclined slots. The utility model is provided with an improved novel contact structure, and three parts of a contact cup seat, a reinforcing rib and a contact support which are usually used in a complicated cup contact structure are eliminated, so three silver-copper solder sheets originally for welding the three parts are saved. The novel contact structure is mainly an integrated copper-chromium alloy contact with six inclined slots capable of generating cross magnetic field.
Description
Technical field:
This use is novel to relate to a kind of vacuum switch tube, especially relates to a kind of vacuum switch tube of novel contact configurations.
Background technology
Vacuum switch tube belongs to the passive electrical vacuum device, and it is supporting with all kinds of different switching mechanisms and form the high, medium and low voltage vaccum electric apparatus.As vacuum circuit-breaker, vacuum load switch, vacuum contactor etc.It is widely used in each industrial circle such as metallurgy, oil, electric railway.
Owing to vacuum switch tube has that volume is little, function admirable, pollution-free, series of advantages such as the life-span long, safe and reliable, suitable frequent operation are developed rapidly.
In the research and development manufacture process of vacuum switch tube, at how enhancing product performance, reduce manufacturing cost again simultaneously as far as possible, experienced test of many times, improvement, especially the structure of contact terminal of switching tube core designer's research and development emphasis especially.In recent years, the product prices of raw and semifnished materials go up significantly, and the production marketing price sharply descends again, and profit margin is very little.Therefore, how optimizing, improve structure of contact terminal is the task of top priority, in the structure of contact terminal of various complexity, its selection be will be different according to vacuum switch tube purposes, the size of drop-out current and deciding will be accomplished thing its value to the greatest extent as far as possible, has given play to its due function to greatest extent.For this reason, we have developed the vacuum switch tube of the novel contact configurations in this case.
As shown in Figure 2, existing structure of contact terminal comprises contact base 15, reinforcement 14, contact tray 10 and contact 6.Locate mutually between them, and weld together with silver-copper brazing alloy 11,12,13.
The utility model content
In order to solve the conspicuous contradiction of vacuum switch tube performance and cost, the purpose of this utility model provides a kind of vacuum switch tube of novel structure of contact terminal.
To achieve these goals, the utility model adopts following technical scheme: a kind of vacuum switch tube of novel contact configurations comprises fairlead, insulation crust, moved end assembly, quiet end assembly, shielding cylinder.An end that it is characterized in that insulation crust is connected with bellows by moving cover plate, and the other end of insulation crust is connected with quiet end assembly by quiet cover plate, and the contact of moved end assembly is corresponding with the contact of quiet end assembly; By the fairlead location, shielding cylinder directly is connected with insulation crust between moving conductive rod and the moving cover plate, and contact is set to integrated chromiumcopper and is provided with six skewed slots.
The utlity model has the novel contact configurations after the improvement, three parts of contact cup, reinforcement, contact tray in the cup-shaped structure of contact terminal of the complexity that cancellation is habitual usually, and saved three silver-copper brazing alloy sheets that were used to weld these three parts originally, novel contact configurations mainly is to have integrated cu cr contact material six skewed slots, that can produce transverse magnetic field.
Description of drawings
Fig. 1 is the vacuum switch tube structural representation;
Fig. 2 is existing structure of contact terminal schematic diagram;
Fig. 3 is the structure of contact terminal schematic diagram after improving.
Embodiment
Further specify below in conjunction with accompanying drawing:
As Fig. 1, shown in Figure 3, a kind of vacuum switch tube of novel contact configurations, it comprises insulation crust 2, moved end assembly 4, quiet end assembly 5, shielding cylinder 3, fairlead 1, an end of insulation crust 2 is connected with bellows 8 by moved end cover plate 7; The other end of insulation crust 2 is connected with quiet end assembly 5 by quiet cover plate 9, and the contact 6 of moved end assembly 4 is corresponding with the contact of quiet end assembly 5, and by fairlead 1 location, shielding cylinder 3 directly is connected with the inwall of insulation crust 2 between moving conductive rod and the moving cover plate 7; It is characterized in that: contact 6 is provided with six skewed slots 16.
Should be pointed out that at last above example only is the representational example of the utility model, obviously, the technical solution of the utility model is not limited to above-mentioned case study on implementation, and many distortion can also be arranged, and all should think protection range of the present utility model.
