Abstract
The utility model relates to an electric appliance switch, in particular to a high-voltage switch with an anti-release device on a contact, which belongs to the field of electric appliances. The high-voltage switch with the anti-release device on the contact comprises a static contact and a movable contact and is characterized in that a latch hook is arranged on the static contact, a pull nose is arranged on the movable contact, an S-shaped locking component with a spring is also hinged on the movable contact, the upper part of the S-shaped locking component coincides with the latch hook, and the lower part is provided with an exposed part inside the pull nose. The high-voltage switch in such a structure has the advantages that the contact of the static contact and the movable contact of the switch is tight, and the movable contact release phenomenon caused by poor contact because of long-time use is avoided.
Description
Technical field
The utility model relates to appliance field, relates to appliance switch, and particularly a kind of contact has the high-voltage switch gear of anti-disengaging device.
Background technology
In the prior art, high-voltage appliance switch has static contact and movable contact spring, static contact relies on identical gap extruding to contact with movable contact spring, the such switch of long-time use, the phenomenon that loose contact will occur, electric discharge phenomena also can be aggravated influence contact effect, thereby influence the normal use of switch.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, provide a kind of static contact of switch that can make to contact with movable contact spring closely, can not make it the long-time loose contact of using occur, make the movable contact spring obscission high-voltage switch gear---contact has the high-voltage switch gear of anti-disengaging device.
The technical solution of the utility model is achieved in that contact has the high-voltage switch gear of anti-disengaging device, comprises static contact and movable contact spring, it is characterized in that: have hook on the static contact; Have the nose of drawing on the movable contact spring, also be hinged with the locking member of the serpentine of a band spring on it, the locking member top of serpentine and hook coincide, and the bottom is drawing the nose the inside that naked leakage part is arranged.
The beneficial effects of the utility model are: such high-voltage switch gear has the static contact that can make switch and contacts with movable contact spring closely, can not make it the long-time loose contact of using occur, and makes the advantage of movable contact spring obscission.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, static contact 2, movable contact spring 3, hook 4, draw nose 5, locking member
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, contact has the high-voltage switch gear of anti-disengaging device, comprises static contact 1 and movable contact spring 2, it is characterized in that: have hook 3 on the static contact 1; Have the nose of drawing 4 on the movable contact spring 2, also be hinged with the locking member 5 of the serpentine of a band spring on it, locking member 5 tops of serpentine and hook 3 coincide, and the bottom is drawing nose 4 the insides that naked leakage part is arranged.
Because spring is arranged, when static contact contacts with movable contact spring, the top of the locking member 5 of serpentine is on hook, play the locking effect, disconnection is to draw nose 4, and simultaneously the also naked leakage part of the locking member 5 of serpentine like this makes it and link up with 3 to come off, reach the effect that falls, such device can prevent that switch from coming off.
