Description

Relay with armature capable of stably resetting

Technical Field

The utility model relates to a relay especially relates to a relay that armature can stably reset.

Background

Relays, which are electronic control devices, are widely used in automatic control circuits. In essence, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like.

The conventional relay includes a housing, a base, a movable spring assembly, a stationary spring assembly, and a linkage assembly, wherein the movable spring assembly, the stationary spring assembly, and the linkage assembly are respectively installed between the housing and the base. The movable spring assembly forms a movable contact. The static spring assembly forms a static contact. The movable contact of the movable spring assembly is switched between a state of being conducted with the stationary contact and another state of being de-energized from the stationary contact by the linkage assembly.

The linkage assembly mainly comprises an armature, a yoke and an electrified coil, wherein the movable spring assembly is arranged on the armature, and one end of the armature is pivotally arranged on the base through the yoke and the electrified coil. Specifically, the armature has a magnetically attracted end and a bent end, wherein the magnetically attracted end is coupled to the electrical coil, and wherein the bent end is pivotally connected to the yoke. When the energizing coil is energized, the magnetic attraction end is coupled to the magnet of the energizing coil, so that the bending end swings, and accordingly the movable spring assembly mounted at the bending end swings and is conducted to the static spring assembly. When the electrified coil is powered off, the movable spring assembly is kept in a power-off state with the static spring assembly.

In order to prevent the magnetic attraction end of the armature from swinging left and right, a limiting bump is usually arranged on a mounting base of the energized coil, wherein the limiting bump is arranged on two sides of the magnetic attraction end to prevent the magnetic attraction end from swinging towards a direction close to the limiting bump. However, the height of the limiting bump is limited, when the relay resonates or falls from a high place to collide, the magnetic attraction end can do irregular movement up, down, left and right, and can be placed at the top of the limiting bump, once the magnetic attraction end of the relay cannot reset, and the movable spring assembly is kept in a power-off state with the static spring assembly.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 to 4, an armature stable reset relay 100 according to a preferred embodiment of the present invention includes a relay assembly 10 and a housing 20, wherein the housing 20 forms a mounting cavity 201, and the relay assembly 10 is mounted in the mounting cavity 201.

Specifically, the housing 20 includes a casing 21 and a substrate 22, and the substrate 22 is covered on the casing 21, wherein the casing 21 forms the mounting cavity 201. After the relay assembly 10 is mounted in the mounting cavity 201, the mounting cavity 201 is covered with the substrate 22.

The relay assembly 10 includes an armature 11, a yoke 12, a coil assembly 13, a movable spring assembly 14, a stationary spring assembly 15, and a mounting base 16.

The armature 11 has a force end 111 and a pivot end 112. The middle portion of the armature 11 is pivotally connected to the mounting base 16 via the yoke 12. The coil assembly 13 forms a magnetic attraction end 131 and is mounted to the mounting base 16. The force receiving end 111 of the armature 11 is coupled to the magnetic attraction end 131 of the coil assembly 13. The movable spring assembly 14 includes a movable spring 141, wherein the movable spring 141 is mounted to the pivot end 112 of the armature 11. The static spring assembly 15 is mounted to the mount 16. When the coil assembly 13 is energized, the magnetically attracting end 131 of the coil assembly 13 will generate magnetism to attract the force-receiving end 111 of the armature 11. Subsequently, the pivot end 112 of the armature 11 will rotate to rotate the movable spring 141 mounted on the pivot end 112 to abut against the static spring assembly 15, so that the movable spring assembly 14 and the static spring assembly 15 are electrically conducted.

In the present invention, the mounting base 16 is provided with a pair of lateral limiting protrusions 161. When the armature 11 is mounted on the mounting seat 16 and coupled to the coil assembly 13, the force-receiving end 111 of the armature 11 is held between the pair of lateral limit protrusions 161, so as to prevent the armature 11 from moving closer to the lateral limit protrusions 161.

In an embodiment of the present invention, the inner wall of the housing 21 is provided with a pair of longitudinal limiting protrusions 211. After the relay assembly 10 is mounted in the mounting cavity 201 formed by the housing 21, the armature 11 is held between the pair of longitudinal limit protrusions 211.

Preferably, in the present invention, after the relay assembly 10 is installed in the installation cavity 201 formed by the housing 21, a pair of the longitudinal limiting protrusions 211 is kept opposite to a pair of the transverse limiting protrusions 161, wherein the force-bearing end 111 of the armature 11 is always kept between a pair of the transverse limiting protrusions 161 and between a pair of the longitudinal limiting protrusions 211. In this way, the force-bearing end 111 of the armature 11 does not rest on the longitudinal limit protrusion 211 when the relay 100, in which the armature can be stably reset, resonates or falls down and vibrates.

It can be understood by those skilled in the art that by providing the longitudinal limiting protrusion 211 on the housing 21, a closed swing space can be formed between one of the lateral limiting protrusions 161, the longitudinal limiting protrusion 211 and the housing 21 after the housing 21, the base plate 22 and the relay assembly 10 are assembled. When the force-bearing end 111 of the armature is stressed to swing, the force-bearing end is limited in the swing space and does not rest on the transverse limiting projection 161 or the longitudinal limiting projection 211. Thus, the armature 11 can be stably reset.

In another embodiment of the present invention, as shown in fig. 4, the end of the lateral limiting protrusion 161 integrally extends to form a longitudinal limiting protrusion 211a, wherein the longitudinal limiting protrusion 211a is configured to limit the swing amplitude of the force-bearing end 111 of the armature 11, so as to always keep the force-bearing end 111 between the pair of lateral limiting protrusions 161 and the pair of longitudinal limiting protrusions 211 a.

In the present embodiment, a limiting opening 1001 is formed between the longitudinal limiting protrusion 211a and the lateral limiting protrusion 161, wherein the force-receiving end 111 of the armature 11 is limited in the limiting opening 1001.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
