Abstract
The utility model discloses an electrical-appliance switch has the self-cleaning function. The switch comprises a casing and a switch mechanism. The switch mechanism mainly comprises a corrugated movable rod, a guiding block, a contact fixing frame, a slow-moving contact frame and a slow spring; two compressed springs are arranged between two contact fixing frames; a dynamic contact is fixed at the outer side of the contact fixing frame; the corrugated movable rod is threaded through the slow-moving contact frame and the guiding block so as to be movably arranged between the guiding blocks; fluctuating up-and-down corrugations are arranged on two outer side walls of the corrugated movable rod which enter the contact fixing frames. As the movable rod used for driving the dynamic contact frame appears as the corrugated movable rod with the fluctuating up-and-down corrugations on the surface; when the corrugated movable rod is threaded into the contact fixing frame, the contact fixing frame and the slow contact fixed on the frame can be driven to sway horizontally so as to generate friction between the dynamic contact arranged on the slow-moving contact frame and the static contact fixed inside the casing, thus removing the oxide layer on the dynamic contact surface and static contact surface and guaranteeing the better contact of the switch.
Description
Technical field
The utility model relates to a kind of electrical switchgear, particularly relates to a kind of appliance switch with self-cleaning function.
Background technology
Existing appliance switch is to drive moving contact on the frame of contact with the fixed contact contact or separate by motion bar, thereby realizes the break-make of switch.This appliance switch of commonly using in use for some time, the easily oxidation and turning black of moving contact and fixed contact surface, it is big that contact resistance becomes, and makes switch contact easily generate heat, ablate, switch life is shorter.
The utility model content
The purpose of this utility model is to provide a kind of appliance switch with self-cleaning function that can grind off oxide layer automatically when work, fall end contact resistance, thereby guarantees that the switch contact is good, and the life-span prolongs.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of appliance switch with self-cleaning function, and it comprises housing and switching mechanism, and switching mechanism is installed in the housing, and fixed contact is installed in the housing inner chamber, and moving contact is installed on the switching mechanism; Described switching mechanism mainly is made up of ripple motion bar, guiding link stopper, contact fixed frame, slow motion contact frame, slow motion spring; Described contact fixed frame is made of left and right contact fixed frame, and this left and right contact fixed frame is provided with in opposite directions, and its middle part hollow out so that the ripple motion bar passes from the middle part, is provided with two compression springs between the fixed frame of left and right contact; The described slow motion contact frame that moving contact is installed is made of left and right slow motion contact frame, is separately fixed at the outside of left and right contact fixed frame; Activity was set between the guiding link stopper after described ripple motion bar passed slow motion contact frame, guiding link stopper, stretched into the ripple that is provided with dipping and heaving on the part lateral wall of contact fixed frame at the ripple motion bar.
The part that described ripple motion bar stretches into the contact fixed frame is the square-section, offers the ripple of dipping and heaving on two relative lateral walls, and the ripple on two lateral walls shifts to install, so that the teeter of contact-actuating fixed frame.
On contact fixed frame and inner wall edge that ripple motion bar two lateral walls cooperate, offer circular arc chamfering.
After adopting such scheme, because the utility model is used to drive the motion bar of moving contact frame has upper and lower fluctuating ripple for the surface ripple motion bar, after this ripple motion bar inserts the contact fixed frame, meeting contact-actuating fixed frame and the slow motion contact frame of fixing on it are done teeter, make to be contained in the moving contact on the frame of slow motion contact and to be fixed between the interior fixed contact of housing and can produce friction, thereby grind off the oxide layer on moving contact and fixed contact surface, contact resistance has fallen at the end, guarantee the good contact of switch, prolonged switch life.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of appliance switch with self-cleaning function, and it comprises housing 1 and switching mechanism 2, and switching mechanism 2 is installed in the housing 1.Fixed contact 3 is installed in the housing inner chamber, and moving contact 4 is installed on the slow motion contact frame 24 of switching mechanism 2.
As Fig. 3, Fig. 4, shown in Figure 5, described switching mechanism 2 mainly is made up of ripple motion bar 21, guiding link stopper 22, contact fixed frame 23, slow motion contact frame 24, slow motion spring 25.Described contact fixed frame 23 is made of left and right contact fixed frame 231,232, this left and right contact fixed frame 231,232 is provided with in opposite directions, its middle part hollow out so that ripple motion bar 21 passes from the middle part, is provided with two compression springs 25 between left and right contact fixed frame 231,232; The described slow motion contact frame 24 that moving contact 4 is installed is made of left and right slow motion contact frame 241,242, is separately fixed at the outside of left and right contact fixed frame 231,232; The left and right slow motion contact frame 241,242 that described ripple motion bar 21 right-to-lefts pass right contact fixed frame 232, left contact fixed frame 231 and are installed on it, last activity penetrates guiding link stopper 22, and the external stability of guiding link stopper 22 is on the inner chamber of housing 1.
The part that described ripple motion bar 21 stretches into contact fixed frame 23 is the square-section, on two relative lateral walls, offer the ripple 211 of dipping and heaving, 212, ripple 211 on the last lateral wall is to shift to install with the ripple 212 on the following lateral wall, promptly, if the crest of the ripple on the last lateral wall 211 for raising up, then descending the ripple 212 on the lateral wall is the trough of indent, so that when ripple motion bar 21 inserts contact fixed frame 23, utilize the ripple 211 of the dipping and heaving on 21 liang of lateral walls of ripple motion bar, 212, along horizontal direction contact-actuating fixed frame 23 and fix slow motion contact frame 24 swing on it, then realize swinging up and down of moving contact 4, (with reference to Fig. 1), when contacting with fixed contact 3, owing to have relative displacement between moving contact 4 and the fixed contact 3, produce friction, thereby remove the oxide layer on surface between the contact, prolong the useful life of switch.
Slick and sly more for contact fixed frame 23 is cooperated with ripple motion bar 21, offer circular arc chamfering 231 at the inner wall edge that 21 liang of lateral walls of contact fixed frame 23 and ripple motion bar cooperate.
Emphasis of the present invention just is: two lateral walls of motion bar are provided with the ripple of dipping and heaving.
