Abstract
The utility model relates to an oil arc-eliminating switch which is used for the alternating current of various occasions such as industrial production, agricultural production, etc., which is particularly suitable for AC motors. A bottom board is provided with a static contact point; a pressure board is provided with a movable contact point; the lower end of an upright post is arranged on the bottom board, the pressure board is arranged on the upright post, and the upright post is sheathed with a spring to divide the pressure board and the bottom board; the lower end of a pressure lever is arranged on pressure board; the bottom board, the pressure board, the upright post and the lower half part of the pressure lever are dipped in the oil of an oil tank, and the upper end of the pressure lever passes through an oil tank cover to be connected with a handle. The utility model does not generate the arc, can not harm bodies and can not burn the contact point, and the utility model has the advantages of safe and convenient use, simple structure, low cost and easy production.
Description
The utility model is a kind of alternating current oil formula arc-suppressing switch that is used for various occasions such as industrial and agricultural production, is specially adapted to alternating current machine.
At present, in the occasion of various use alternating currents, particularly in the occasion of alternating current machine, what use often is disconnecting link formula switch and air switch.In use there is following deficiency in these two a little switches: 1. be easy to generate electric arc, the electric arc of Chan Shenging directly produces injury to human body sometimes, uses dangerous; 2. burn out the contact easily.
The purpose of this utility model is to design a kind of arc-suppressing switch of oily formula, can not produce electric arc, also can not burn out the contact, and is safe and convenient to use.
The utility model is equipped with fixed contact on base plate, moving contact is housed on the pressing plate, the lower end of column is contained on the base plate, pressing plate is contained on the column, being with spring on the column separates pressing plate and base plate, the lower end of depression bar is contained on the pressing plate, base plate, pressing plate, column, and the latter half of depression bar be immersed in the oil in the fuel tank, the upper end of depression bar is passed fuel tank cap and is linked to each other with handle.
To contact more firmly in order making between moving contact and fixed contact, moving contact to be contained on the moving contact bar, the moving contact bar is contained on the pressing plate, on the moving contact bar spring is housed.
When electric conducting materials such as using metal is made fuel tank, can base plate be fitted on the insulation board, on fuel tank, make the hole of reaching the standard grade, and load onto the sealed insulation sleeve pipe in the online hole.
In use, with handle by depression bar with pressing plate to pressing down, make the moving contact energized that contacts with fixed contact; When release handle, because the effect of column upper spring, pressing plate is upwards boosted, and moving contact and fixed contact are separated to cut off the electricity supply.Because moving contact and fixed contact all are soaked in the oil in the fuel tank, thereby can produce electric arc, can not burn out the contact yet.
Can on fuel tank cap, mounting and positioning device be located by handle, make moving contact and fixed contact can keep in touch state.
The utlity model has following advantage:
1. because moving contact and fixed contact all are operated in the oil, can produce electric arc, thereby can not damage the person;
2. do not have electric arc to produce, can not burn out the contact of switch yet;
3. simple in structure, cost is low, be easy to manufacture.
Accompanying drawing is embodiment of the present utility model.
The utility model will be further described below in conjunction with the embodiment of accompanying drawing.
1. on the base plate (15) fixed contact (14) is housed, the lower end of column (13) is contained on the base plate (15), pressing plate (4) is contained on the column (13), being with spring (12) on the principal post (13) separates pressing plate (4) and base plate (15), the lower end of depression bar (9) is contained on the pressing plate (4), base plate (15), pressing plate (4), column (13), and the latter half of depression bar (9) be immersed in the oil in the fuel tank (3), the lid (2) that fuel tank (3) are passed in the upper end of depression bar (9) links to each other with handle (1).
2. moving contact (7) is contained on the moving contact bar (6), and moving contact bar (6) is contained on the pressing plate (4), and spring (5) is housed on the moving contact bar (6).
3. base plate (15) is pressed on the insulation board (16), is shaped on line hole (11) on the fuel tank (3), and sealed insulation sleeve pipe (10) is housed in line hole (11).
Among this embodiment, on the lid (2) of fuel tank (3), a hook (8) is housed, keeps its state when being used to depress handle (1).
The moving contact of this embodiment (7) can directly be contained on the pressing plate (4), does not use the spring (5) on moving contact bar (6) and the moving contact bar (6).
Claims (3)
1, oily formula arc-suppressing switch, it is characterized in that: fixed contact (14) is housed on the base plate (15), moving contact (7) is housed on the pressing plate (4), the lower end of column (13) is contained on the base plate (15), pressing plate (4) is contained on the column (13), being with spring (12) on the column (13) separates pressing plate (4) and base plate (15), the lower end of depression bar (9) is contained on the pressing plate (4), base plate (15), pressing plate (4), column (13), and the latter half of depression bar (9) be immersed in the oil in the fuel tank (3), the lid (2) that fuel tank (3) are passed in the upper end of depression bar (9) links to each other with handle (1).
2, oily formula arc-suppressing switch as claimed in claim 1 is characterized in that: moving contact (7) is contained on the moving contact bar (6), and moving contact bar (6) is contained on the pressing plate (4), and spring (5) is housed on the moving contact bar (6).
