Description

Technical Field

[0001] The utility model relates to the technical field of relays, and particularly relates to a relay. Background Art

[0002] A relay is an electrical device used to control a larger power circuit through a smaller control signal. It usually consists of an electromagnetic system (including a coil, an iron core, a reed, etc.) and one or more groups of contacts. Relays play an important role in various applications, such as in the fields of home automation, industrial control systems, automotive electronics, communication equipment, etc. When the existing relay works, the reed swings and contacts the contact to transmit an electrical signal. During the swinging process of the reed, vibration will occur. Frequent vibration may cause the offset of the contact end of the reed, so that it cannot be accurately aligned with the contact, resulting in the abnormal operation of the relay. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a relay aiming at the current situation of the prior art.

[0004] The technical solution adopted by the utility model to solve the above technical problem is to propose a relay, comprising:

[0005] A base frame;

[0006] A limiting member, which is arranged on the base frame;

[0007] A swinging member, which is swingably arranged on the base frame. The swinging member is provided with an opening part, and the opening part is in movable abutment with the limiting member;

[0008] When the limiting member abuts against the opening part, the limiting member is used to limit the movement of the swinging member.

[0009] In the above-mentioned relay, the limiting member is set as a convex platform, and the upper end surface of the convex platform is not lower than the lower end surface of the upper end of the swinging member.

[0010] In the above-mentioned relay, the swinging member comprises: a reed, which is swingably arranged on the base frame; a fixing part, which is connected with the reed and is fixedly arranged on the base frame.

[0011] In the above-mentioned relay, it comprises: a swinging block, which is fixedly arranged on the reed and is used to provide buffering for the swinging of the reed.

[0012] In the above-mentioned relay, it comprises: a housing, which is sleeved on the base frame. The housing is provided with a limiting block, and the limiting block plays a role in limiting the base frame.

[0013] In the above-mentioned relay, it includes: a contact, the contact is arranged on the base frame, and the contact is in movable abutment with the contact end of the reed.

[0014] In the above-mentioned relay, it includes: an electromagnet, the electromagnet is arranged on the base frame, and the electromagnet is in movable abutment with the swing block.

[0015] In the above-mentioned relay, it includes: a plug, the plug is arranged on the lower end face of the base frame.

[0016] Compared with the prior art, the advantage of the present utility model is that when the swing member swings, the limiting member abuts against the opening portion arranged on the swing member, thereby restricting the movement of the swing member in the direction perpendicular to the swing direction, reducing the vibration of the swing member, ensuring that the contact end of the swing member will not shift, and enabling the relay to work stably.

[0022] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0023] As Figures 1 to 4 shown, a relay of the present utility model includes:

[0024] Base frame 1; limiting member 2, the limiting member 2 is arranged on the base frame 1; swing member 3, the swing member 3 is swingably arranged on the base frame 1, the swing member 3 is provided with an opening portion 310, and the opening portion 310 is in movable abutment with the limiting member 2.

[0025] When the swing member 3 swings, the limiting member 2 abuts against the opening 310 provided on the swing member 3, thereby restricting the movement of the swing member 3 in the direction perpendicular to the swing direction, reducing the vibration of the swing member 3, and ensuring that the contact end of the swing member 3 does not shift.

[0026] In this solution, the limiting member 2 is provided as a boss 210, and the upper end surface of the boss 210 is not lower than the lower end surface of the upper end of the swing member 3. When the swing member 3 swings, it will vibrate, thereby generating movement in the direction perpendicular to the swing direction, causing the boss 210 to abut against the opening 310. The boss 210 exerts a thrust perpendicular to the swing direction on the swing member 3, thereby restricting the movement of the swing member 3.

[0027] In this solution, the swing member 3 includes: a reed 320, the reed 320 is swingably arranged on the base frame 1; a fixing portion 330, the fixing portion 330 is connected to the reed 320, and the fixing portion 330 is fixedly arranged on the base frame 1. The upper end of the swing member 3 is fixed on the base frame 1 through the fixing portion 330. The reed 320 is made of metal, can swing on the base frame 1, and can reset under the action of its own elasticity.

[0028] This solution further includes: a swing block 4, the swing block 4 is fixedly arranged on the reed 320, and the swing block 4 is used to provide buffering for the swing of the reed 320. And the swing block 4 can also separate the reed 320 from the electromagnet 7, preventing the reed 320 from contacting the electromagnet 7 when the relay is energized, thereby avoiding arc discharge and causing damage to the reed 320 and the electromagnet 7.

[0029] This solution further includes: a housing 5, the housing 5 is sleeved on the base frame 1, and the housing 5 is provided with a limiting block 510, and the limiting block 510 plays a role in limiting the base frame 1. The housing 5 can protect the internal components of the relay, making the internal components not easily damaged. The limiting block 510 restricts the position of the base frame 1, leaving a gap between the housing 5 and the frame, providing space for the movement of the swing member 3.

[0030] This solution further includes: a contact 6, the contact 6 is arranged on the base frame 1, and the contact 6 is in movable abutment with the contact end of the reed 320. When the relay is energized, the reed 320 swings, causing the contact end of the reed 320 to separate from the contact 6, thereby disconnecting the circuit.

[0031] This solution further includes: an electromagnet 7, the electromagnet 7 is arranged on the base frame 1, and the electromagnet 7 is in movable abutment with the swing block 4. After the relay is energized, the electromagnet 7 pulls the reed 320 to swing, causing the reed 320 to separate from the contact 6, thereby disconnecting the circuit.

[0032] This solution further includes: a plug 8, the plug 8 is arranged on the lower end surface of the base frame 1, and the plug 8 is inserted into the socket to energize the relay, and the plug 8 is pulled out of the socket to de-energize the relay.

[0033] When the swing member 3 swings, the limiting member 2 abuts against the opening 310 provided on the swing member 3, thereby restricting the movement of the swing member 3 in the direction perpendicular to the swing direction, reducing the vibration of the swing member 3, ensuring that the contact end of the swing member 3 does not shift, and enabling the relay to work stably.
