Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific example, to the present invention
It is further described.It should be noted that the direction term mentioned in example, for example, "upper", "lower", " in ", " left side " " right side ",
"front", "rear" etc. is only the direction with reference to attached drawing.Therefore, the direction used is intended merely to explanation and is not intended to limit the invention
Protection scope.
Referring to Fig. 1, a kind of shock proof TO-5 relay, including sealing shell, and the electricity being arranged in sealing shell
Magnetic system 1 and contact system 2.Electromagnetic system 1 is by coil group, armature 1-1, armature 1-1 group, iron core, magnetizer, support plate group
At.Electromagnetic system 1 is the control section of relay, and effect is to convert electromagnetic energy into mechanical energy, and drive contact system 2
The closing or opening of contact.Contact provides by pedestal group, front contact spring, dynamic circuit connector back contact spring, quiet conjunction back contact spring, returns spring and form.Contact
System 2 is the execution part of relay, and effect is to turn on or disjunction outside electrical circuit.Swash when the coil of electromagnetic system 1 applies
When encouraging, the electromagnetism power drive armature 1-1 that coil inside magnetic field generates rotates, and the pushers on armature 1-1 contact system
The movable contact spring of system 2 disconnects normally-closed contact, normally opened contact is closed.When the coil of electromagnetic system 1 does not apply excitation, coil inside
Magnetic field disappears, and is acted on by the counter-force returned spring and touch each touching spring of contact system 2, so that armature 1-1 is returned to original state, make normally opened touching
Point disconnects, normally-closed contact is closed.

Degree is less than the width of right flank 1-1-4；It is symmetrically opened at the top edge of the upper limb 1-1-1 of armature 1-1 and the lower edge of bottom wing 1-1-2
Equipped with the axis hole 1-1-5 worn for rotation axis.Since armature 1-1 of the invention is the asymmetrical cross in symmetrical above and below and left and right
The mass center 1-1-6 of structure, armature 1-1 is located on the lateral cross centre line of armature 1-1, and is located at longitudinal cross of armature 1-1
The right side of center line.
The line of centres, that is, center of rotation of 2 axis hole 1-1-5 is parallel to each other with the lateral cross centre line of armature 1-1, and two
Person can not be overlapped has a certain distance between the two, can also overlap.In a preferred embodiment of the invention, 2
The line of centres of axis hole 1-1-5 is overlapped with the lateral cross centre line of armature 1-1.The overall width of armature 1-1 is total with armature 1-1's
The ratio of length is in the range of 1/3~1/2.The line of centres, that is, the center of rotation and rank of 2 axis hole 1-1-5 of armature 1-1
The mass center 1-1-6 distance l of iron 1-1 accounts for the ratio of the total length L of armature 1-1 in the range of 0~1/4.The present invention is by changing
The mass ratio for becoming the length-width ratio of armature 1-1, center of rotation two sides, can reduce armature 1-1 mass center 1-1-6 and center of rotation away from
From, while reducing the quality of armature 1-1, to achieve the purpose that the shock resistance for promoting product.
It should be noted that although the above embodiment of the present invention be it is illustrative, this be not be to the present invention
Limitation, therefore the invention is not limited in above-mentioned specific embodiment.Without departing from the principles of the present invention, all
The other embodiment that those skilled in the art obtain under the inspiration of the present invention is accordingly to be regarded as within protection of the invention.
