Abstract
The utility model relates to a double alloy-piece structure designed for a security switch. The double alloy pieces are set as a quadrangle demi-body with two short sides and two long sides. The two short sides of the double alloy pieces are set as a fixed side of a base pin in the security switch and a moving side combined with a moving contact respectively; the other two long sides are set as a connection side; a saddle groove is prepared on the fixed side, and the double alloy-piece plate is bent to form a concave arch naturally; the other side of the arch, when being heated, rises and breaks off from the fixed contact of the switch; however, different depths of saddle grooves influence the sensitivity of the double alloy-pieces, therefore, double alloy-pieces meeting the characteristics of electrical products can be produced if the depth of the saddle groove is adjusted during molding.
Description
[technical field]
The utility model is a kind of pairing gold plaque structure of safety switch, is the parts design that belongs to appliance switch.
[background technology]
In order to prevent electric appliance load excessive and damage; therefore; generally on appliance switch, can be provided with overload protection arrangement; on the whole it utilize the shell fragment of pairing gold plaque as movable contact; when electric current (load) is excessive; the pairing gold plaque is temperature distortion and make movable contact break away from fixed contact to form and open circuit, damage to avoid electrical equipment.And the pairing gold plaque will have its escape characteristic, just must do a kind of processing and forming on the pairing gold plaque makes it produce a suitable binding force, when current overload, produce heat and cause the distortion of pairing gold, when producing a pin during greater than the binding force on the pairing gold plaque, deflection takes off action, and the form of pairing gold plaque and specification have several, respectively has different characteristics, demand (magnitude of current of for example different electrical equipment and load limit difference) in response to different electrical equipment, when machine-shaping, need be controlled, for example a kind of form of pairing gold plaque being arranged is directly to make concave arc shape in the lamellar body upper punch, when it is used in the demand of different electrical equipment, essential careful actuarial metallic character, the concave arc degree, the degree of depth and quite difficult control, another kind is as shown in Figure 6, make the lateral plate (41) that is positioned at both sides and has a free end in pairing gold plaque (40) plate body upper punch, and the position is in the middle of the plate body and have a free-ended tongue piece (42), this tongue piece (42) free end is fixed with a movable contact (43) as shown in Figure 7, the then displacement in opposite directions of two free ends of lateral plate (41), be fixed on pin (50) top of switch with more close kenel, make two lateral plates (41) because free end mutually near and fettered, promptly make the plate body stage casing be arcs of recesses, when tongue piece (42) free end is suppressed downwards and is conducting state, pairing gold plaque (40) is to be the downward invaginated type in stage casing, when making pairing gold plaque (40) heating and distortion when overload again, promptly make pairing gold plaque (40) be the stage casing shape that upwards arches upward, make tongue piece (42) and movable contact (43) escape and open circuit.Yet, it only is fixed on the pin toward intrinsic displacement by lateral plate (41) free end of pairing gold plaque (40), so pairing gold plaque binding force is fixed, can't adjust the size of control pairing gold plaque binding force, and can not meet different electrical equipment demands fully, insufficient sensitivity and still have anxiety safe in utilization.
From the above, two kinds of common pairing gold plaque kenels all have to be difficult for manufacturing the required specification of the opering characteristic of electric apparatus, and the necessity that is improved are arranged.
[summary of the invention]
In order to improve above-mentioned disappearance, the main purpose of the utility model is to provide a kind of pairing gold shell fragment that can conveniently make the safety switch of adjustment.
Based on above-mentioned purpose, the major technique means system of the utility model is the quadrangle lamellar body with two minor faces and two long limits with the pairing gold plaque, two minor faces are defined as the wherein fixed edge of a pin that is fixed in switch respectively, and the active edges that is combined with a movable contact, be provided with a recessed saddle groove in fixed edge, and the width of fixed edge system is narrower than active edges.
By above-mentioned technological means, the degree of depth of saddle groove can influence the sensitivity of pairing gold plaque, so as long as change the demand that the degree of depth of saddle groove can meet the different opering characteristics of electric apparatus during moulding, not only make things convenient for machining control, more can suit the security needs of electric equipment products.

[embodiment]
See also shown in Figure 1, the pairing gold elastic piece structure of the safety switch that the utility model provided, it mainly is made as pairing gold plaque (10) the quadrangle lamellar body with two minor faces and two long limits, wherein two minor faces of pairing gold plaque (10) are defined as fixed edge (11) respectively, active edges (12), other two long limits then are defined as fillet (13), go up punch forming one saddle groove (14) in active edges (12), width with reduction fixed edge (11), make pairing gold plaque (10) plate body be concave arc shape naturally, the bottom land of this saddle groove (14) is provided with a perforation (110), use on the wherein pin that is fixed in safety switch, in addition in this end rivet clasp one movable contact (20) of active edges (12), because pairing gold plaque (10) is concave arc shape, past opposite side arches upward and makes movable contact (20) escape when it is heated, in addition, the degree of depth of this saddle groove (14) will influence the sensitivity of pairing gold plaque (10), when saddle groove (14) is dark more, its sensitivity is poor more, that is temperature distortion temperature required high more (electrical equipment that is fit to high ampere), otherwise, when saddle groove (14) is shallow more, its sensitivity high more (electrical equipment that is fit to low-amperage), so can be required during its moulding in response to the different opering characteristics of electric apparatus, saddle groove (14) degree of depth when adjusting moulding gets final product.
Fig. 2 and for example, shown in Figure 3 is the another kind of embodiment of the utility model, it is fixed edge (11 ') at pairing gold plaque (10 '), active edges (12 ') goes up the saddle groove (15 ') (14 ') (the saddle groove of being located on the fixed edge is darker) of moulding different depth respectively, the sensitivity of pairing gold plaque (10 ') temperature distortion is the depth difference that is decided by two saddle grooves (15 ') (14 '), when the depth difference of two saddle grooves (15 ') (14 ') is got over for a long time, the electrical equipment of the poor and suitable more high ampere of sensitivity, it also is that the degree of depth of setting saddle groove (15 ') (14 ') when seeing through moulding can be in response to required electrical equipment.
As Fig. 4, shown in Figure 5 be that the third of the utility model implemented kenel, it is to be provided with saddle groove (15 ") in the fixed edge of pairing gold plaque (10 ") (11 "); and the width of fixed edge (11 ") is made as is narrower than active edges (12 "); and be provided with a tongue piece towards fixed edge (11 ") extension (16 ") in the middle of the active edges (12 "), fixing movable contact (20) on tongue piece (16 ") free end; this embodiment is located at saddle groove (15 ") on the fixed edge (11 ") of pairing gold plaque (10 "), uses on the pin that is positioned safety switch.
In addition, be provided with the embodiment of tongue piece based on above-mentioned centre, the utility model can also be equipped with the saddle groove at two ends, and the degree of depth of two saddle grooves is differed.
