Example 1

The embodiment provides an auxiliary contact assembly 5, which is suitable for the technical field of relays. As shown in fig. 1 to 6, the auxiliary contact assembly 5 includes an auxiliary stationary contact terminal 51 and an auxiliary movable contact spring 52, the auxiliary movable contact spring 52 being adapted to contact with or separate from the auxiliary stationary contact terminal 51.

The shape of the auxiliary movable reed 52 provided in this embodiment is similar to a strip structure, and defines the direction of movement of the auxiliary movable reed 52 relative to the auxiliary stationary contact leading end 51 as a first direction, the first direction is denoted by D1, the length direction of the auxiliary movable reed 52 is a second direction, the second direction is denoted by D2, the width direction of the auxiliary movable reed 52 is a third direction, the third direction is denoted by D3, the first direction, the second direction and the third direction are perpendicular to each other, wherein the first direction, the second direction and the third direction only represent space directions, and are not significant.

The auxiliary stationary contact lead-out terminal 51 provided in this embodiment includes a lead-out terminal body 511, the lead-out terminal body 511 includes a first contact portion 5115, the auxiliary movable spring piece 52 includes a second contact portion 524, and the second contact portion 524 of the auxiliary movable spring piece 52 is in contact with or separated from the first contact portion 5115 of the auxiliary stationary contact lead-out terminal 51; the first contact portion 5115 and the second contact portion 524 have a contact force when in contact, and the direction of the contact force intersects with a first direction, which is a movement direction of the auxiliary movable contact spring 52 with respect to the auxiliary stationary contact terminal 51.

The contact force between the first contact portion 5115 and the second contact portion 524 can be decomposed into a component force F1 in the first direction and a component force F2 in the second direction, so that the stress of the auxiliary movable reed 52 is reduced, the situation that the second contact portion 524 of the auxiliary movable reed 52 is damaged or worn seriously to cause failure is avoided, and the service life and reliability of the auxiliary movable reed 52 are improved.

It should be noted that, the number of the first contact portion 5115 and the second contact portion 524 may be plural, or plural contacts may be provided on the first contact portion 5115 and the second contact portion 524, or plural contacts may be provided on one contact portion to cooperate with another contact portion, so as to form an auxiliary multi-contact structure, where plural means two or more.

In one embodiment, the first contact 5115 is disposed obliquely with respect to the first direction such that the direction of the contact force intersects the first direction.

Since the first fixing portion 5111 is extended in the first direction, if the first fixing portion 5111 and the first contact portion 5115 are collinear, the first contact portion 5115 and the second contact portion 524 of the auxiliary movable spring 52 are in point contact, and the contact force is vertically concentrated on the second contact portion 524, which is liable to cause contact damage. The first contact portion 5115 is disposed obliquely with respect to the first direction, and the first fixing portion 5111 and the first contact portion 5115 are not collinear, but have a certain inclination angle therebetween, so that an included angle exists between the first contact portion 5115 and the second contact portion 524, and the contact force can be decomposed into a component force F1 in the first direction and a component force F2 perpendicular to the first direction, thereby reducing the occurrence of breakage or abrasion of the second contact portion 524 of the auxiliary movable reed 52, and improving the service life and reliability of the auxiliary movable reed 52.

In one embodiment, the second contact 524 is disposed obliquely to the second direction such that the direction of the contact force intersects the first direction.

In other words, the second contact portion 524 does not extend in a standard horizontal direction, and the second contact portion 524 has a certain inclination angle with respect to the second direction, so that the first contact portion 5115 and the second contact portion 524 are in contact.

Wherein, the auxiliary movable contact spring 52 is bent along the two ends of the second direction towards the direction close to the auxiliary stationary contact leading end 51 to form an auxiliary movable contact. In this way, the contact reliability of the auxiliary movable reed 52 and the auxiliary stationary contact leading-out end 51 is improved, and meanwhile, the link of assembling the auxiliary movable reed 52 and the auxiliary movable contact is reduced, so that the production cost is saved.

In one embodiment, there is a point contact between the first contact 5115 and the second contact 524. In the point contact, the contact force intersects the first direction, and the contact force can be decomposed into a component force F1 in the first direction and a component force F2 in the direction perpendicular to the first direction, so that the damage or abrasion of the second contact portion 524 of the auxiliary movable reed 52 is reduced, and the service life and reliability of the auxiliary movable reed 52 are further improved.

Wherein, the auxiliary movable reed 52 and the auxiliary stationary contact leading-out end 51 are of a normally open structure.

In one embodiment, an auxiliary movable contact is provided on a side of the auxiliary movable reed 52 facing the auxiliary stationary contact leading end 51, and an auxiliary normally open stationary contact is provided on the auxiliary stationary contact leading end 51 corresponding to the auxiliary movable contact, and the auxiliary movable contact is in contact with or separated from the auxiliary normally open stationary contact.

In one embodiment, as shown in fig. 6-7, the auxiliary stationary contact terminal 51 is of a bent configuration.

In one embodiment, as shown in fig. 6 to 7, the auxiliary stationary contact terminal 51 includes a first fixing portion 5111, and the first contact portion 5115 is disposed at an end of the first fixing portion 5111 facing the second contact portion 524, and the first fixing portion 5111 and the second contact portion 524 are arranged along the first direction.

The first fixing portion 5111 is relatively fixed in position, and the first fixing portion 5111 and the second contact portion 524 are arranged in the first direction and in the up-down direction, but not the first fixing portion 5111 and the second contact portion 524 are contacted, but the auxiliary stationary contact leading-out terminal 51 is of a bent structure, so that the first contact portion 5115 and the second contact portion 524 can be contacted.

In one embodiment, the first fixing portion 5111 is disposed to extend in the first direction. That is, the first fixing portion 5111 is substantially a needle-shaped structure disposed in a vertical direction.

It should be noted that, the first fixing portion 5111 is not disposed directly under the auxiliary movable spring 52 in the first direction, but the first fixing portion 5111 is located at the outer side of the auxiliary movable spring 52 in the second direction, and the bent portion 5112 is a contact position with the auxiliary movable spring 52, so that the first fixing portion 5111 provides support for the bent portion 5112 and also avoids the contact position.

In one embodiment, the auxiliary stationary contact terminal 51 further includes a bent portion 5112, and the bent portion 5112 is disposed between the first fixing portion 5111 and the first contact portion 5115. Wherein, the bending portion 5112 and the first fixing portion 5111 form an included angle therebetween.

It should be noted that, an included angle is formed between the bending portion 5112 and the first fixing portion 5111, so that the auxiliary stationary contact lead-out terminal 51 is entirely of a bending structure, and it does not mean that the bending portion 5112 itself has a certain bending angle.

The included angle between the bending portion 5112 and the first fixing portion 5111 provided in this embodiment is specifically an acute angle, at this time, one end of the bending portion 5112 away from the first fixing portion 5111 is a free end, and a contact area between the auxiliary movable reed 52 and the auxiliary stationary contact leading end 51 is provided between the connection position between the bending portion 5112 and the first fixing portion 5111 and the free end.

If the auxiliary movable contact lead-out end 51 is in a needle-shaped structure, when the auxiliary movable reed 52 and the auxiliary movable contact lead-out end 51 just contact the over-travel process, the acting force applied by the auxiliary movable reed 52 by the auxiliary movable contact lead-out end 51 is a vertical acting force along the first direction, and the auxiliary movable reed 52 is stressed at a single point, namely, only the position of the auxiliary movable reed 52 corresponding to the auxiliary movable contact lead-out end 51 is stressed locally, and the position is easy to damage in the long-time use process of the relay, so that the service life is influenced.

To solve this problem, as shown in fig. 6 to 7, the first contact portion 5115 provided in the present embodiment is provided with a contact cambered surface 5110 on a side facing the auxiliary movable reed 52, and the contact cambered surface 5110 can be in contact with the auxiliary movable reed 52 and can slide with respect to the auxiliary movable reed 52.

Specifically, the contact cambered surface 5110 is of an arc structure, the contact cambered surface 5110 is a contact position with the auxiliary movable reed 52, the acting force applied by the contact cambered surface 5110 to the auxiliary movable reed 52 is not a vertical acting force along the first direction, but is an acting force perpendicular to the tangential direction between the contact cambered surface 5110 and the auxiliary movable reed 52, the acting force F can be divided into a first acting force F1 along the first direction and a second acting force F2 along the second direction, and the second acting force F2 is a component force along the horizontal direction, so that the component force first acting force F1 along the vertical direction is reduced, the pressure applied to the auxiliary movable reed 52 is effectively reduced, and the service life of the auxiliary movable reed 52 is prolonged.

In addition, the contact cambered surface 5110 can slide relative to the auxiliary movable spring plate 52, the bending part 5112 has a certain sliding track in the contact process, namely, along with the movement of the pushing assembly 4, the contact position between the auxiliary movable spring plate 52 and the bending part 5112 continuously slides to form a linear track, the contact position between the contact cambered surface 5110 and the auxiliary movable spring plate 52 is not the same position, the single-point stress and continuous stress conditions of the auxiliary movable spring plate 52 are reduced, the stress positions of the auxiliary movable spring plate 52 are dispersed, the damage failure of the auxiliary movable spring plate 52 is reduced, and the service life of the auxiliary movable spring plate 52 is prolonged.

In one embodiment, as shown in fig. 6 to 7, the first fixing portion 5111, the first contact portion 5115, and the bending portion 5112 are integrally formed.

Specifically, the end of the first fixing portion 5111 far away from the yoke plate 6 is bent relative to the first fixing portion 5111 to form a bending portion, so that the manufacturing process is simple, the links of part assembly are saved, and the production cost is relatively low.

Of course, the auxiliary movable reed 52 and the auxiliary movable contact may be separately provided, or may be an integrally formed structure; the auxiliary stationary contact leading-out terminal 51 and the auxiliary normally open stationary contact may be provided separately or may be an integrally formed structure. In addition, the specific contact form between the auxiliary movable reed 52 and the auxiliary stationary contact terminal 51 is not limited in this embodiment, and it is within the scope of this embodiment as long as contact or separation between the auxiliary movable reed 52 and the auxiliary stationary contact terminal 51 can be achieved.

In other words, the bent portion 5112 of the auxiliary normally open stationary contact lead-out end is provided above the auxiliary movable reed 52 in the first direction.

In one embodiment, the bending portion 5112 of the auxiliary stationary contact terminal 51 is bent in the second direction and toward the second fixing portion 523 to form an auxiliary normally open stationary contact terminal.

The connection member 513 is specifically a transition copper sheet, the connection member 513 is disposed between the insulation member 512 and the yoke plate 6, and the connection member 513 serves as an intermediate connection between the yoke plate 6 and the insulation member 512.

When the active reed 22 breaks down and has high current, the anti-short circuit component 3 can form a magnetic conduction loop and generate suction force, and the suction force is used for resisting electric repulsive force generated between the active reed 22 and the main static contact leading-out end 21 due to fault current, so that the condition that arc discharge explosion is caused by mutual separation between the active reed 22 and the main static contact leading-out end 21 is avoided, and the contact reliability and safety of the active reed 22 and the main static contact leading-out end 21 are ensured.
