Abstract
A wall switch with protection function comprises a lock catch, a jump pin and a contact support piece, wherein the lock catch and the jump pin are mounted on the corresponding positions of the contact support piece; a gap is arranged on the lock catch, the surface on the upper end of the gas is an arc surface, the shaft of the arc surface of the lock catch is coaxial with a transmission shaft of the lock catch, during the working process, the lock catch is locked or tripped with the jump pin by the arc surface; after the lock catch is locked with the jump pin, the direction of the contact pressure of the lock catch and the jump pin is perpendicular with the movement direction of the lock catch when the lock catch is tripped from the jump pin. Thus the stress of the lock catch is simple, the tripping force is easy to control, and the stability and reliability of the products are conveniently improved.
Description
Technical field
The utility model relates to a kind of switch on wall with defencive function, particularly with the switch on wall of creepage protection function.
Background technology
Protect with electric leakage, overload, short circuit etc. that the switch on wall of defencive function is mainly used in household electrical appliance; its version has multiple; but substantially all has a kind of free handle that is formed by contact supporter, snap close, tripping etc.; when switch closes a floodgate; fasten between snap close and the tripping; when snap close and tripping were triped, switch is disjunction just.Because there are some defectives in existing switch on wall with defencive function in the design of free handle, the bad phenomenon such as tripping force is unstable can appear often, cause the potential safety hazards such as the insensitive or action inefficacy of action.Had a strong impact on product quality.
Summary of the invention
The problems referred to above in view of having now with the switch on wall of defencive function the utility model proposes a solution, stability and the reliability of the switch on wall of its energy Effective Raise band defencive function.
The solution that the utility model is taked is: a kind of switch on wall with defencive function comprises: snap close 1, tripping 2, contact supporter 3; It is characterized in that: a breach is arranged on the snap close 1, in indentation, there arc surface 102 is arranged, snap close 1 fastens by arc surface 102 and tripping 2 or trips in the course of work.During fastening, the direction of tripping 2 and the contact of snap close 1 direction of motion of snap close when triping is orthogonal; Arc surface 102 is coaxial with snap close axle 101, makes mechanism all can make tripping working face 202 keep tangent with the arc surface 102 of snap close 1 in the whole rotation process of triping.The frictional force that normal pressure when the factor of decision tripping force size just only has self-fastening button 1 and tripping 2 to fasten like this produces, snap close 1 is stressed simple, is easy to control its size and stable.The tripping force of switch can remain stable like this, is conducive to improve stability and the reliability of product.

Contact supporter figure among Fig. 3 the utility model embodiment
The title of parts shown in the mark is as follows among the figure:
1 snap close; 101 snap close axles; 102 arc surfaces; 2 trippings; 201 tripping installation axle hole; 202 tripping working faces; 203 transmission axis holes; 3 contact supporters; 301 snap close installing holes; 302 tripping installing holes; 303 center of rotation;
Embodiment
Referring to Fig. 1, a kind of switch on wall with defencive function comprises: snap close 1, tripping 2, contact supporter 3, it is characterized in that: a breach is arranged on the described snap close 1, in indentation, there arc surface 102 is arranged, there is snap close axle 101 lower end of snap close 1, and the arc surface 102 of snap close 1 is coaxial with snap close axle 101; Snap close 1 is installed in snap close installing hole 301 places of contact supporter 3 by snap close axle 101, and snap close 1 can be around the center rotating of snap close installing hole 301 in the course of work.Described tripping 2 is installed in the position of the tripping installing hole 302 of contact supporter 3 by tripping installing hole 201; Tripping 2 can be rotated around tripping installing hole 302; Arc surface 102 and the tripping working face 202 of snap close 1 can fasten or trip.Snap close 1, tripping 2 and contact supporter 3 are combined into one under the buckling state, and can rotate around the center of rotation 303 of contact supporter 3.Can realize closing a floodgate and separating brake to switch by the operating physical force that transmission axis hole 203 places is applied different directions.Under buckling state, if snap close 1 apply one with the tripping force that fastens opposite direction, just snap close 1 and tripping 2 are triped, thereby can allow switch realize trip free.
