Abstract
The utility model relates to a power switch arc extinguishing shield. A main body of the power switch arc extinguishing shield consists of a switch shell and a button mounted on the upper portion of the switch shell, a fixed contact and a movable contact are disposed at the bottom of the switch shell, and the movable contact corresponds to the fixed contact and is combined with the same,. The power switch arc extinguishing shield is characterized in that an arc extinguishing shield is additionally arranged above the movable contact and comprises arc extinguishing partition boards and an arc extinguishing bent plate, the arc extinguishing partition boards are vertically disposed on two sides of the fixed contact, and the arc extinguishing bent plate is arranged above the movable contact. Alternatively, the arc extinguishing shield consists of an arc extinguishing straight plate and shell lateral wings, the arc extinguishing straight plate is horizontally mounted above the movable contact, and the shell lateral wings are arranged inside the switch shell. When the switch is started in a dark environment, the movable contact and the fixed contact in the switch contact with each other, so that electric arc is generated. Electric arc spark generated inside the switch can be sealed by the aid of the arc extinguishing shield, and accordingly, safety in use of an electric appliance is improved.
Description
Technical field
The utility model relates to a kind of locking device, especially relates to a kind of mains switch arc-extinguish chamber that is applied to switch enclose inside electric arc flame.
Background technology
At present, be applied to control apparatus and start the switch that stops, the sound contact and the middle gap that can have to a certain degree of button of playing electric action are installed in the switch housing inside to be existed, when starting and stopping, the motion of shift knob drives the sound contact and is in contact with one another generation electric arc flower, and mains switch inside does not have setting up of some retention devices, arclight can occur in the switch use, especially in dark surrounds, can occur causing the visual sense of insecurity of user than the forceful electric power arc light.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of arclight that stops and leaks, and plays the mains switch arc-extinguish chamber of vision safe effect.
The technical scheme in the invention for solving the technical problem is: a kind of mains switch arc-extinguish chamber, main body is switch housing and the button that is installed in switch housing top, bottom in switch housing is provided with fixed contact, and the moving contact that exists corresponding to fixed contact combination, the top of described moving contact adds an arc-extinguish chamber.
For the arclight that will produce is enclosed in the certain space, described arc-extinguish chamber is made up of arc extinguishing dividing plate that vertically is built up in the fixed contact both sides and the arc extinguishing bent plate that is installed in the moving contact top.
For simplified structure, the switch housing of utilization own, described arc-extinguish chamber is installed in the straight plate of arc extinguishing of moving contact top by level and the shell flank of switch housing inside is formed.
The beneficial effects of the utility model are: the utility model installs arc-extinguish chamber additional between switch contact and button space, and the arclight that produces in the switch use is isolated, even also can not see arc light in dark surrounds, strengthens electrical equipment sense safe in utilization.
Description of drawings
Fig. 1 is the schematic diagram that the utility model is cut the shell flank open;
Fig. 2 cuts arc extinguishing dividing plate schematic diagram open in the utility model;
Fig. 3 is the schematic diagram that the utility model another kind is cut the shell flank open.
Among the figure: 1, button 2, switch housing 2-1, shell flank 3, moving contact 4, fixed contact 5, arc-extinguish chamber 6, arc extinguishing dividing plate 7, arc extinguishing bent plate 8, the straight plate of arc extinguishing.
Embodiment
A kind of mains switch arc-extinguish chamber shown in Figure 1, main body is switch housing 2 and the button 1 that is installed in switch housing 2 tops, bottom in switch housing 2 is provided with fixed contact 4, and makes up the moving contact 3 that exists corresponding to fixed contact 4, and the top of described moving contact 3 adds an arc-extinguish chamber 5.Between moving contact 3 and button 1 space, install arc-extinguish chamber 5 additional, the arclight that produces in the switch use is isolated,, strengthen electrical equipment sense safe in utilization even in dark surrounds, also can not see arc light.
Arc-extinguish chamber 5 shown in Figure 2 is made up of arc extinguishing dividing plate 6 that vertically is built up in fixed contact 4 both sides and the arc extinguishing bent plate 7 that is installed in moving contact 3 tops, and the arclight that produces is enclosed in the certain space.
Arc-extinguish chamber 5 shown in Figure 3 is installed in the straight plate 8 of arc extinguishing of moving contact 3 tops by level and the shell flank 2-1 of switch housing 2 inside forms the switch housing of utilization own, simplified structure.
