Abstract

The utility model provides a small high-power relay which comprises a base, a yoke, a framework wound with coils and an outer casing. The yoke and the framework are arranged on the base, and at least one limiting block for abutting against the framework or the yoke is arranged at the bottom inside the outer casing. According to the small high-power relay, the at least one limiting block is arranged at the bottom inside the outer casing, when the relay is assembled, the at least one limiting block can abut against the framework or the yoke to prevent the framework from moving and the coils from loosing, and the stability and the reliability are high.

Description

Small high-power relay
Technical field:
The utility model relates to the relay field, relates in particular to a kind of small high-power relay.
Background technology:
Relay is a kind of switching device with Current Control, usually is applied in the automatic control circuit, and it is actually a kind of a kind of " automatic switch " with the larger electric current of small electric diffluence control is requisite device in the automatic control circuit.(the small-sized size of longest edge that generally refers to is greater than 10mm for small high-power relay, and the relay less than 25mm, the high-power relay of rated current more than 10A that refer to) because its volume is little, high-power advantage is widely used in household electrical appliance, communication equipment and the automobile circuit etc.
Existing small high-power relay comprises shell, pedestal, two static contact spring pieces, movable contact spring, armature, yokes and is twining the skeleton of coil, skeleton and yoke are installed on the pedestal, one end and the yoke of movable contact spring are fixed, middle part and the armature of movable contact spring are fixed, the other end of movable contact spring is provided with moving contact, described the first static contact spring piece is provided with the first fixed contact, the second static contact spring piece is provided with the second fixed contact, moving contact and the first fixed contact or the second fixed contact are fitted, during assembling, described jacket and is connected with pedestal around coil.This small high-power relay, the inner bottom part of shell is not established guide vane end stop, then also leaves the space between the inner bottom part of coil and skeleton and shell, if after the collision, skeleton may be movable, even break away from from pedestal, stability and reliability are lower.
The utility model content:
The technical problem that the utility model solves is, overcomes existing technological deficiency, and the small high-power relay that a kind of stability is high, reliability is high is provided.
The technical scheme that the utility model provides is: the utility model provides a kind of small high-power relay, it comprises pedestal, yoke, is twining skeleton and the shell of coil, described yoke and skeleton are installed on the pedestal, and the inner bottom part of described shell is provided with the guide vane end stop that at least one is used for and skeleton or yoke offset.
In the utility model, at the inner bottom part of shell guide vane end stop is set, in the relay assembling time limit, guide vane end stop can offset with skeleton or yoke, prevents that skeleton is movable, and coil is loosening, and stability and reliability are higher.
Description of drawings:
Accompanying drawing 1 is the cross-sectional schematic of the utility model small high-power relay;
Accompanying drawing 2 is the part-structure schematic diagram that does not contain shell of the utility model small high-power relay;
Accompanying drawing 3 is the structural representation of the shell of the utility model small high-power relay;
As shown in the figure: 1, pedestal, 2, yoke, 3, coil, 4, skeleton, 5, shell, 5.1, guide vane end stop.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Such as Fig. 1, Fig. 2, shown in Figure 3: the utility model provides a kind of small high-power relay, it comprises pedestal 1, yoke 2, is twining skeleton 4 and the shell 5 of coil 3, described yoke 2 and skeleton 4 are installed on the pedestal 1, and the inner bottom part of described shell 5 is provided with the guide vane end stop 5.1 that at least one is used for and skeleton 4 or yoke 2 offset.
In the utility model, at the inner bottom part of shell 5 guide vane end stop 5.1 is set, in the relay assembling time limit, guide vane end stop 5.1 can offset with skeleton 4 or yoke 2, prevents that skeleton is movable, and coil is loosening, and stability and reliability are higher.
