Abstract
The utility model discloses a kind of iron core on relay, it comprises body (1), be located at the location shaft shoulder (2) of body (1) one end and be located at the riveted joint block (3) of body (1) other end, it is characterized in that: the shape of cross section of described riveted joint block (3) is for circular, the shape of cross section of described body (1) is oval, and the major axis of the oval cross section of described body (1) is greater than the diameter of the circular cross section of riveted joint block (3), the axis of described riveted joint block (3) and the extended line conllinear of body (1) axis.The utility model provides one can make to install firmly between coil and iron core, and coil is not easy the iron core on relay that rotates around the axis of iron core.
Description
Technical field
The utility model relates to the technical field of relay, specifically a kind of iron core on relay.
Background technology
Relay has more and more been applied in automatic control circuit as a kind of electronic control device.And comparatively conventional in existing relay be electromagnetic relay, its operation principle is the coil electricity making to be wrapped on columnar iron core in simple terms, makes armature be attracted on iron core by galvanomagnetic effect, thus realizes the conversion of the on off operating mode of contact.And the two ends of described coil are connected with the power supply of control circuit, therefore, the relay of prior art in use accommodating coil and the iron core of causing skids, thus rotates the end of a thread of coil and power supply are disconnected.Especially for when having the relay plant equipment of vibrations using the prior art, described iron core and coil are under vibration environment, and useful life is shorter, and failure rate is higher.
Summary of the invention
Technical problem to be solved in the utility model is: provide one can make to install firmly between coil and iron core, and coil is not easy the iron core on relay that rotates around the axis of iron core.
Technical solution adopted in the utility model is: provide a kind of iron core on relay, it comprises body, be located at the location shaft shoulder of body one end and be located at the riveted joint block of the body other end, the shape of cross section of described riveted joint block is circular, the shape of cross section of described body is oval, and the major axis of the oval cross section of described body is greater than diameter, the axis of described riveted joint block and the extended line conllinear of body axis of the circular cross section of riveted joint block.
After adopting above structure, a kind of iron core on relay of the present utility model compared with prior art has the following advantages: by the shape of cross section of body is set to ellipse, therefore when coil winding is on body, circumference carried out to coil spacing, prevent coil from body, rotating skidding.
Improve as one, the described location shaft shoulder is provided with circumferential position-limit mechanism.Can effectively prevent iron core of the present utility model from rotating relative to casing of relay by arranging circumferential position-limit mechanism on the shaft shoulder of location; therefore compared with prior art only to rely on the tensile force of the riveted joint block of riveting process to carry out circumference spacing; the circumferential restraining ability of iron core of the present utility model is more firm; can better coil be protected, prevent the junction of coil and power supply from rupturing.
As preferably, described circumferential position-limit mechanism refers to, the described location shaft shoulder is provided with straight flange.
Further, described circumferential position-limit mechanism refers to, the shape of cross section of the described location shaft shoulder is oval.
Improve as one, the other end that described riveted joint block deviates from body is provided with hole slot, the equal conllinear of extended line of the respective axis of described riveted joint block, hole slot and body.By arranging a hole slot on riveted joint block, can greatly reduce in riveting process, to rivet the stamping press needed for block distortion by the design of hole slot, therefore can use very little stamping press that the annulus on riveted joint block can be made to be out of shape, reach riveted joint effect, simultaneously less stamping press and the axial impact force greatly reducing iron core body and bear, decrease the risk of distortion.
Improve as one, the diameter d 1 of described hole slot bottom land position is less than the diameter d 2 of hole slot openend position.Described hole slot is up big and down small structure, not only can prevent from punching course, riveting block towards crimp in hole slot, and can prevent from riveting rupturing along hole slot bottom land position of block.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model provides a kind of iron core on relay, it comprises body 1, be located at the location shaft shoulder 2 of body 1 one end and be located at the riveted joint block 3 of body 1 other end, it is characterized in that: the shape of cross section of described riveted joint block 3 is for circular, the shape of cross section of described body 1 is oval, and the major axis of the oval cross section of described body 1 is greater than diameter, the axis of described riveted joint block 3 and the extended line conllinear of body 1 axis of the circular cross section of riveted joint block 3.
The described location shaft shoulder 2 is provided with circumferential position-limit mechanism.
Described circumferential position-limit mechanism refers to, the described location shaft shoulder 2 is provided with straight flange 2.1.
Described circumferential position-limit mechanism refers to, the shape of cross section of the described location shaft shoulder 2 is oval.
The other end that described riveted joint block 3 deviates from body 1 is provided with hole slot 3.1, the equal conllinear of extended line of the respective axis of described riveted joint block 3, hole slot 3.1 and body 1.
The diameter of described hole slot 3.1 bottom land position is less than the diameter of hole slot 3.1 openend position.
Its operation principle is, iron core is inserted in the housing of relay, the location shaft shoulder 2 on iron core body 1 of the present utility model is leant with the side of housing, meanwhile, riveted joint block 3 on body 1 other end extend in the through hole of the opposite side of housing, then the iron core assembled is communicated with housing to be riveted by riveting machine, thus riveted joint block 3 distortion is fixed with housing.Namely described riveted joint block 3 flattens under the punching press effect of riveting machine, is fitted on the sidewall of housing, finally makes body 1 spacing in casing of relay.In the process, it is spacing that described coil carries out circumference by the ellipsoidal structure on body, and described body then carries out spacing by the straight flange 2.1 of locating the shaft shoulder 2 with the housing of relay.
