Abstract
The utility model relates to an electricity leaking switch tripper which is composed of a casing, a bottom board and tripping components. The utility model is characterized in that the bottom board is provided with screws, the screws and the bottom board form a flexible connection, the screws are connected with the springs of the tripping components by joints, the joints and the screws form a flexible connection, and the other end of each spring is connected with the armature iron of each tripping component. The utility model overcomes the defects that the ordinary electricity leaking switch tripper has multiple misoperations, and the performance is not stable. The utility model has the advantages of adjustable elastic pulling force, simple structure and serviceable range enlargement.
Description
The utility model relates to a kind of leakage switch release.
Existing leakage switch release generally all is made of housing, base plate, yoke, coil, armature, magnet steel and spring etc., and the resetting of armature is that the pulling force of spring is a fixed value by finishing with base plate affixed spring.Because the influence of various factors, as influence the cleannes of the factor of soft magnetic material, the factor that influences hard magnetic material, working surface and assembling condition or the like, the I value is fluctuateed (according to stipulating 1/2I among the GB6829-86
ΔN＜I
ΔN＜I
ΔN is considered as qualified products), therefore also different to the requirement of spring, the misoperation of I value hour, product is serious, and when I was big, the qualification rate that jeopardizes people's security of the lives and property, product was low.
The purpose of this utility model is to overcome the above-mentioned deficiency of common leakage switch release and provide a kind of simple in structure, the leakage switch release of adjustable springs pulling force.
The utility model is made of shell, base plate and release member, push rod below in the release member is provided with armature, armature contacts with two contacts of yoke, one side suit coil of yoke, opposite side is fixed by magnetic yoke, be provided with between magnetic yoke and the armature every the magnetic liner, the below of yoke is a magnet steel, on the coil by the rivet stationary spring, one end of spring leaf and an end of armature offset, this subtracting point is connected with an end of spring, and base plate is provided with the screw with its loose joint, and screw is again by being connected with the other end of spring with the joint of its loose joint.When electric leakage takes place when, induction coil work, armature overcomes the pulling force of spring, ejects push rod, and deenergization guarantees personal safety, and by regulating the screw on the base plate, with regard to the pulling force of may command spring, it is satisfied the demand.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model is by shell (6), base plate (9) and release member constitute, the below of the push rod in the release member (1) is provided with armature (12), the other end stretches out outside the housing (6), armature (12) contacts with two contacts of yoke (3), one side suit coil (2) of yoke (3), opposite side is fixing by magnetic yoke (10), be provided with every magnetic liner (4) between magnetic yoke (10) and the yoke (3), in case leak-stopping magnetic, the below of yoke (3) is provided with magnet steel (11), and coil (2) is gone up by rivet (14) stationary spring (13), and an end of an end of spring leaf (3) and armature (12) offsets, this subtracting point is connected with an end of spring (5), thereby makes armature (12) be in the equilbrium position.On base plate (9), also be provided with screw (8) with its loose joint, this loose joint mode can adopt and be spirally connected, and screw (8) is again by being connected with the other end of spring (5) with the joint (7) of its loose joint, like this, when threading off use, can come the pulling force of control spring by adjustment screw (8).
The utility model so the pulling force of back-moving spring is regulated, has enlarged the scope of application of release by above-mentioned concrete structure greatly.Simultaneously, simple in structure, reliable in action height of the present utility model is a kind of leakage switch release that is worthy of popularization.
Claims (1)
1, a kind of leakage switch release, by shell, base plate and release member constitute, push rod below in the release member is provided with armature, armature contacts with two contacts of yoke, one side suit coil of yoke, opposite side is fixed by magnetic yoke, be provided with between magnetic yoke and the armature every the magnetic liner, the below of yoke is a magnet steel, by the rivet stationary spring, an end of spring leaf and an end of armature offset on the coil, and this subtracting point is connected with an end of spring, it is characterized in that: also be provided with the screw (8) with its loose joint on the base plate (9), screw (8) is again by being connected with the other end of spring (5) with the joint (7) of its loose joint.
