Abstract
The utility model discloses a kind of magnetic path of relay, comprise coil (1), yoke (2) and skeleton (3), the two ends of described skeleton (3) are respectively equipped with an installing hole, and the two ends of described coil (1) are separately fixed in the installing hole of the correspondence of skeleton (3); Described yoke (2) is in L-type, minor face is fixed on one side of skeleton (3), the axis direction at long edge coil (1) and the side of skeleton (3) are affixed, the two ends of described skeleton (3) are connected to coil lead pin, and the both sides of described skeleton (3) are installed coil terminal pin (4) position and are equipped with one group of position limiting structure.The magnetic path of this relay reduces number of spare parts, reduces assembling and congratulates, prevents framework collapse.
Description
Technical field
The utility model relates to relay technical field, specifically a kind of magnetic path of relay.
Background technology
During relay work, as long as add certain voltage at coil two ends, will flow through certain electric current in coil, thus produce galvanomagnetic effect, armature promotes dynamic spring by push rod, until dynamic spring and quiet spring adhesive.When after coil blackout, the suction of electromagnetism also disappears thereupon, and armature returns to original position, and dynamic spring is separated with quiet spring.
There is a kind of magnetic path of relay at present, comprise coil, yoke and skeleton, the two ends of described skeleton are provided with two installing holes, the two ends of described coil are separately fixed in the installing hole of the correspondence of skeleton, described yoke is L-type, minor face is fixed on one side of skeleton, and the axis direction of long edge coil and the side of skeleton are affixed, and the two ends of described skeleton are connected to coil lead pin.There is following shortcoming in the magnetic path of the relay of this structure above:
1, coil lead pin is first welded and fixed with the installing rack on skeleton, then with coil coiling outlet be connected, cause complex structure like this, number of spare parts is many, and too increases assembly process simultaneously, adds cost.
2, the sidewall thickness due to skeleton is thinner, after installing rack embeds, very easily causes framework collapse, thus coil lead pin is come off.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of and reduces number of spare parts, reduces the magnetic path that the relay of framework collapse was congratulated, prevented in assembling.
The technical solution of the utility model is, a kind of magnetic path with the relay of following structure is provided, comprise coil, yoke and skeleton, the two ends of described skeleton are respectively equipped with an installing hole, the two ends of described coil are separately fixed in the installing hole of the correspondence of skeleton, described yoke is L-type, minor face is fixed on one side of skeleton, the axis direction of long edge coil and the side of skeleton are affixed, the two ends of described skeleton are connected to coil lead pin, and the both sides of described skeleton are installed coil terminal pin position and are equipped with one group of position limiting structure.
Often organize position limiting structure and comprise the first groove and the second groove, described first groove is positioned at the base of skeleton, and described second groove is positioned at the edge of the madial wall of skeleton, described first groove and the second texturearunaperpendicular.
The end, outer end of described second groove is provided with the projection extended laterally, is provided with spacing between described first groove and the second groove.
After adopting above structure, the utility model compared with prior art, has the following advantages:
1, because the installation coil terminal pin position, both sides of described skeleton is equipped with one group of position limiting structure, can coil lead pin be directly embedded in skeleton, eliminate original installing rack, again with coil coiling outlet be connected, this spline structure is simple, number of spare parts is few, and decreases assembly process simultaneously, reduces cost.
2, due in the unaltered situation of the sidewall thickness of skeleton, additionally do not embed other parts, avoid softened, avoid framework collapse, thus prevent coil lead pin from coming off.
As improvement, often organize position limiting structure and comprise the first groove and the second groove, described first groove is positioned at the base of skeleton, described second groove is positioned at the edge of the madial wall of skeleton, described first groove and the second texturearunaperpendicular, good limit effect, comprises axially and radial spacing, thus better fixed coil terminal pin.
As improvement, the end, outer end of described second groove is provided with the projection extended laterally, is provided with spacing between described first groove and the second groove, increases isolation effect.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the magnetic path of relay of the present utility model.
As shown in the figure: 1, coil, 2, yoke, 3, skeleton, the 3.1, first groove, the 3.2, second groove, 3.3, protruding.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the magnetic path of relay of the present utility model, comprise coil 1, yoke 2 and skeleton 3, the two ends of described skeleton 3 are respectively equipped with an installing hole, the two ends of described coil 1 are separately fixed in the installing hole of the correspondence of skeleton 3, described yoke 2 is in L-type, minor face is fixed on one side of skeleton 3, the axis direction of long edge coil 1 and the side of skeleton 3 are affixed, the two ends of described skeleton 3 are connected to coil lead pin 4, the both sides of described skeleton 3 are installed coil terminal pin position and are equipped with one group of position limiting structure, can coil lead pin be directly embedded in skeleton like this, eliminate original installing rack, again with coil coiling outlet be connected, cause structure simple like this, number of spare parts is few, and decrease assembly process simultaneously, reduce cost.Again due in the unaltered situation of the sidewall thickness of skeleton, additionally do not embed other parts, avoid softened, avoid framework collapse, thus prevent coil lead pin from coming off.
Often organize position limiting structure and comprise the first groove 3.1 and the second groove 3.2, described first groove 3.1 is positioned at the base of skeleton 3, and described second groove 3.2 is positioned at the edge of the madial wall of skeleton 3, and described first groove 3.1 is vertical with the second groove 3.2.Good limit effect, comprises axially and radial spacing, thus better fixed coil terminal pin.
The end, outer end of described second groove 3.2 is provided with the projection 3.3 extended laterally, is provided with spacing between described first groove 3.1 and the second groove 3.2, increases isolation effect.
