The TO-5 relay (Transistor Outline) has the characteristics of small volume, light weight, compatibility with ICs and the like by referring TO the appearance of the transistor, and is an indispensable key component for electrical equipment, remote control equipment and ground measurement and control equipment for a long time. In recent years, the requirements of the measurement and control devices on the severe environment resistance of the relay are higher and higher. In the equipment with high impact, strong collision, high frequency vibration and other use conditions in certain specific occasions, the environment adaptability, especially the impact resistance, of the relay has the use requirement of more than 150g and 6 ms.
However, at present, the impact indexes of the TO-5 relays at home and abroad are basically 100g and 6ms, and the use requirement of control equipment or a system on high impact indexes cannot be met. According TO the product structure, TO improve the impact resistance index of the TO-5 relay, the common method is TO increase the contact pressure of the relay and increase the counter force of the return reed, but after the return force is increased, TO ensure that each electrical parameter of the product is unchanged, the ampere turns of the product are required TO be increased by adopting a method for increasing the wire diameter of the coil enameled wire TO improve the electromagnetic magnetic attraction of the electromagnetic system, but due TO the limited internal space of the product, the impact index improving capability of the product is limited by adopting the method.

The invention aims TO solve the problem that the impact index of the traditional TO-5 relay is basically difficult TO meet the use requirement of control equipment or a system on a high impact index, and provides an impact-resistant TO-5 relay.
In order to solve the problems, the invention is realized by the following technical scheme:
an impact resistant TO-5 relay includes a sealed enclosure, and a contact system and an electromagnetic system disposed within the sealed enclosure; the electromagnetic system comprises an iron core, a rotating shaft and an armature; the armature is connected with the iron core through a rotating shaft; the armature is in a cross shape as a whole; the armature is vertically symmetrical about the transverse cross center line of the armature, the length of the upper wing of the armature is equal to that of the lower wing, and the width of the upper wing of the armature is equal to that of the lower wing; the armature is asymmetric left and right about the longitudinal cross center line, and the length of the left wing of the armature is smaller than that of the right wing; the width of the left wing of the armature is smaller than that of the right wing; the upper edge of the upper wing and the lower edge of the lower wing of the armature are symmetrically provided with shaft holes for the rotating shaft to pass through.
In the above solution, the centre of mass of the armature is located on the transverse cross-line of the armature and to the right of the longitudinal cross-line of the armature.
In the scheme, the ratio of the center connecting line of the 2 shaft holes of the armature to the center of mass distance of the armature to the total length of the armature is in the range of (0, 1/4).
In the above scheme, the ratio of the total width of the armature to the total length of the armature is [1/3,1/2].

The mode of reducing the overall dimension and the quality of the armature is achieved by changing the structure of the armature, and compared with the mode of increasing the wire diameter of the enameled wire of the relay coil to improve the ampere-turn number and promote the electromagnetic attraction force, the method is more beneficial to production and realization and is also more convenient to use in a microminiature sealed relay.

Detailed Description
The present invention will be further described in detail with reference to specific examples in order to make the objects, technical solutions and advantages of the present invention more apparent. In the examples, directional terms such as "upper", "lower", "middle", "left", "right", "front", "rear", and the like are merely directions with reference to the drawings. Accordingly, the directions of use are merely illustrative and not intended to limit the scope of the invention.
Referring TO fig. 1, an impact resistant TO-5 relay includes a sealed enclosure, and an electromagnetic system 1 and a contact system 2 disposed within the sealed enclosure. The electromagnetic system 1 consists of a coil group, an armature 1-1 group, an iron core, a magnetizer and a supporting disc. The electromagnetic system 1 is the control part of a relay, which functions to convert electromagnetic energy into mechanical energy and to bring about the closing or opening of the contacts of the contact system 2. The contact is composed of a base set, a movable contact spring, a static contact spring and a return spring. The contact system 2 is an actuator part of a relay, which functions to switch on or off an external electrical circuit. When the coil of the electromagnetic system 1 is excited, electromagnetic force generated by the magnetic field in the coil drives the armature 1-1 to rotate, and a pusher on the armature 1-1 pushes a movable reed of the contact system 2 to open the normally closed contact and close the normally open contact. When the coil of the electromagnetic system 1 is not excited, the magnetic field in the coil disappears, and the armature 1-1 is returned to the initial state by the reaction of the return springs and the contact springs of the contact system 2, so that the normally open contact is opened and the normally closed contact is closed.
The general structure and working principle of the electromagnetic system 1 and the contact system 2 of the present invention are the same as or similar to the prior art, and the main improvement point is the armature 1-1 structure of the electromagnetic system 1. In the electromagnetic system 1, an armature 1-1 is connected to a core through a rotating shaft.
The structure of the armature 1-1 of the electromagnetic system 1 of the conventional relay is shown in fig. 2, and because the mass center 1-1-6 of the armature 1-1 of the structure is far from the rotating shaft, the mass is large, and larger electromagnetic force is needed when the armature 1-1 rotates.
The structure of the armature 1-1 of the electromagnetic system 1 of the relay of the invention is shown in fig. 3, and the armature 1-1 is in a cross shape as a whole. The armature 1-1 is vertically symmetrical about its transverse cross center line; the length of the upper wing 1-1-1 of the armature 1-1 is equal to the length of the lower wing 1-1-2, and the width of the upper wing 1-1-1 of the armature 1-1 is equal to the width of the lower wing 1-1-2; the armature 1-1 is asymmetric left and right about its longitudinal cross center line; the length of the left wing 1-1-3 of the armature 1-1 is smaller than that of the right wing 1-1-4; the width of the left wing 1-1-3 of the armature 1-1 is smaller than the width of the right wing 1-1-4; the upper edge of the upper wing 1-1-1 of the armature 1-1 and the lower edge of the lower wing 1-1-2 are symmetrically provided with shaft holes 1-1-5 for the rotating shaft to pass through. Because the armature 1-1 of the invention is of a cross structure which is symmetrical up and down and asymmetrical left and right, the centroid 1-1-6 of the armature 1-1 is positioned on the transverse cross center line of the armature 1-1 and is positioned on the right side of the longitudinal cross center line of the armature 1-1.
The central connecting line of the 2 shaft holes 1-1-5, namely the rotation center, is parallel to the transverse cross center line of the armature 1-1, and the two can be misaligned, namely a certain distance exists between the two, or the two can be mutually overlapped. In the preferred embodiment of the invention, the center line of the 2 shaft bores 1-1-5 coincides with the transverse cross center line of the armature 1-1. The ratio of the total width of the armature 1-1 to the total length of the armature 1-1 is in the range of 1/3 to 1/2. The ratio of the distance L between the center line of the 2 shaft holes 1-1-5 of the armature 1-1, i.e. the center of rotation, and the center of mass 1-1-6 of the armature 1-1 to the total length L of the armature 1-1 is in the range of 0-1/4. According to the invention, the length-width ratio of the armature 1-1 and the mass ratio of the two sides of the rotation center are changed, so that the distance between the mass center 1-1-6 of the armature 1-1 and the rotation center can be reduced, and the mass of the armature 1-1 is reduced, thereby achieving the purpose of improving the shock resistance of a product.
It should be noted that, although the examples described above are illustrative, this is not a limitation of the present invention, and thus the present invention is not limited to the above-described specific embodiments. Other embodiments, which are apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein, are considered to be within the scope of the invention as claimed.
