Description

Technical Field

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

[0002] A relay is an electrical control device, mainly used for functions such as remote control, signal conversion, and circuit protection in an automatic control system; as a type of relay, a dual-path on-off relay can control the on-off of two circuits simultaneously and is suitable for application scenarios that require dual control; traditional dual-path on-off relays usually adopt an electromagnetic design, and the closing and opening of contacts are driven by electromagnetic force.

[0003] Deficiencies of the prior art:

[0004] 1. Reliability problem: Traditional electromagnetic relays may have problems such as weakened magnetism or burned-out coils due to long-term use, affecting the service life and reliability of the relays.

[0005] 2. Noise problem: Electromagnetic relays may generate relatively large noise during operation, especially in the case of high-frequency switching.

[0006] 3. Precision and stability: Traditional relays may experience jitter during the switching process, affecting the stability and precision of the circuit.

[0007] Therefore, there are deficiencies in the prior art and further improvement is needed. Summary of the Utility Model

[0008] In view of the problems existing in the prior art, the utility model provides a dual-path on-off relay.

[0009] To achieve the above object, the specific scheme of the utility model is as follows:

[0010] The utility model provides a dual-path on-off relay, including: a stationary component, a moving component, and a driving component;

[0011] The stationary component includes two static terminals, and each static terminal is provided with a static contact;

[0012] The moving component includes two moving terminals, and each moving terminal is connected with a moving contact;

[0013] The driving component is used to drive the two moving contacts to contact or move away from the two static contacts, thereby realizing the connection and disconnection of the dual-path circuit;

[0014] The driving component includes a motor, a turbine, a worm, and two sector gears;

[0015] The turbine is installed on the rotor of the motor, and the worm is installed on the first rotating shaft. The turbine and the worm are meshed and connected. Two sector gears are arranged at both ends of the worm and simultaneously rotate through the second rotating shaft. The gear end of the sector gear is meshed and connected with the worm, and the other end of the sector gear is connected with a moving contact through a connecting member.

[0016] The motor is used to drive the turbine and the worm to rotate forward and backward, thereby driving the gear end of the sector gear to move up and down. Since the sector gear rotates through the second rotating shaft, the other end of the sector gear drives the connecting member and the moving contact to move up and down, realizing the contact or separation of the moving contact from the static contact, and realizing the connection and disconnection of the circuit.

[0017] Further, a strip-shaped through groove penetrating left and right is arranged at one end of the sector gear connected with the connecting member, and an arc-shaped groove is arranged at the end of the strip-shaped through groove.

[0018] Further, a sliding rod is arranged at one end of the connecting member connected with the sector gear, and the sliding rod is located in the strip-shaped through groove.

[0019] When the gear end of the sector gear is at the highest and lowest positions during the movement driven by the worm, the sliding rod is located in the arc-shaped groove of the strip-shaped through groove, realizing self-locking.

[0020] Further, a three-stack double-fold elastic sheet assembly is also arranged between the moving terminal and the moving contact;

[0021] The three-stack double-fold elastic sheet assembly is composed of three mutually stacked elastic sheets.

[0022] Further, each elastic sheet is provided with an S-shaped bend to improve the elasticity of the elastic sheet.

[0023] Further, the static terminal is L-shaped.

[0024] Further, the static component, the moving component, and the driving component are arranged in a housing. Among them, one end of both the static terminal and the moving terminal is located outside the housing.

[0025] Adopting the technical solution of the present utility model has the following beneficial effects:

[0026] 1. Improve reliability and durability: The motor drive is adopted to replace the traditional electromagnetic drive method, reducing the failure rate caused by the change of electromagnetic force, and improving the reliability and durability of the relay.

[0027] 2. Enhance control accuracy: The turbine and worm mechanism is precisely controlled by the motor, and then the contact and separation of the moving contact and the static contact are precisely controlled, enhancing the control accuracy of the relay.

[0028] 3. Realize the self-locking function: The bar-shaped through groove and arc-shaped groove on the sector gear cooperate with the design of the slide rod to realize the self-locking function at a specific position, ensuring the stability and safety of the contact position.

[0029] 4. Reduce noise level: Motor drive is smoother than electromagnetic drive. Combined with self-locking mechanism and high elastic spring assembly, it can effectively reduce the noise generated when the relay is working. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Combined Figures 1-9 As shown, the present utility model provides a two-way on-off relay, including:

[0048] A stationary component, a moving component, and a driving component;

[0049] The stationary component includes two static terminals 1, and each static terminal 1 is provided with a static contact 2; the static terminal 1 is L-shaped;

[0050] The moving component includes two moving terminals 3, and each moving terminal 3 is connected with a moving contact 4;

[0051] The driving component is used to drive the two moving contacts 4 to contact or move away from the two static contacts 2, so as to realize the connection and disconnection of the dual-circuit;

[0052] The driving component includes a motor 5, a turbine 6, a worm 7, and two sector gears 8;

[0053] The turbine 6 is installed on the rotor of the motor 5, the worm 7 is installed on the first rotating shaft 9, the turbine 6 and the worm 7 are meshed and connected, the two sector gears 8 are arranged at both ends of the worm 7 and rotatably penetrate through the second rotating shaft 10 at the same time, the gear end of the sector gear 8 is meshed and connected with the worm 7, and the other end of the sector gear 8 is connected with the moving contact 4 through a connecting piece 11;

[0054] The motor 5 is used to drive the turbine 6 and the worm 7 to rotate forward and backward, and then drive the gear end of the sector gear 8 to move up and down. Since the sector gear 8 rotatably penetrates through the second rotating shaft 10, the other end of the sector gear 8 drives the connecting piece 11 and the moving contact 4 to move up and down, realizing the contact or separation of the moving contact 4 from the static contact 2, and realizing the connection and disconnection of the circuit.

[0055] One end of the sector gear 8 connected to the connecting piece 11 is provided with a strip-shaped through groove 12 penetrating left and right, and an arc-shaped groove 13 is arranged at the end of the strip-shaped through groove 12.

[0056] One end of the connecting piece 11 connected to the sector gear 8 is provided with a sliding rod 14, and the sliding rod 14 is located in the strip-shaped through groove 12;

[0057] When the gear end of the sector gear 8 is at the highest and lowest positions during the movement driven by the worm 7, the sliding rod 14 is located in the arc-shaped groove 13 of the strip-shaped through groove 12 to realize self-locking.

[0058] A triple-folded double-folded elastic sheet assembly 15 is further arranged between the moving terminal 3 and the moving contact 4;

[0059] The triple-folded double-folded elastic sheet assembly 15 is composed of three mutually stacked elastic sheets, and each elastic sheet is provided with an S-shaped bend to improve the elasticity of the elastic sheet.

[0060] The stationary component, the moving component, and the driving component are arranged in a housing 16. Among them, one end of both the static terminal 1 and the moving terminal 3 is located outside the housing 16.

[0061] The principle of the present utility model is as follows:

[0062] Working process of the driving component:

[0063] After the motor 5 is started, the turbine 6 starts to rotate. The turbine 6 meshes with the worm 7 and drives the worm 7 to rotate along the first rotating shaft 9. The rotation of the worm 7 causes the two sector gears 8 at both ends to rotate synchronously.

[0064] The gear end of the sector gear 8 meshes with the worm 7, and the other end is connected to the moving contact 4 through the connecting piece 11.

[0065] When the motor 5 drives the turbine 6 and the worm 7 to rotate forward and backward, the sector gear 8 moves up and down along the second rotating shaft 10.

[0066] As the sector gear 8 moves, the connecting piece 11 drives the moving contact 4 to move up and down, realizing the contact or separation between the moving contact 4 and the static contact 2, and further controlling the connection or disconnection of the circuit.

[0067] Self-locking mechanism:

[0068] One end of the sector gear 8 connected to the connecting piece 11 is provided with a strip-shaped through groove 12, and the end of the strip-shaped through groove 12 has an arc-shaped groove 13. The sliding rod 14 of the connecting piece 11 is located in the strip-shaped through groove 12. When the sector gear 8 reaches the highest or lowest position driven by the worm 7, the sliding rod 14 will enter the arc-shaped groove 13 of the strip-shaped through groove 12 to realize self-locking and prevent the moving contact 4 from accidentally changing its position when there is no power input.

[0069] Function of the shrapnel assembly:

[0070] A triple-folded and double-folded shrapnel assembly 15 is arranged between the moving terminal 3 and the moving contact 4. Each shrapnel has an S-shaped bend. This design improves the elasticity of the shrapnel. The shrapnel assembly can provide additional elastic support when the moving contact 4 moves, ensuring the tightness and stability when the moving contact 4 contacts the static contact 2.

[0071] Overall structural design:

[0072] All components of the relay (static components, moving components, driving components) are encapsulated in a housing 16. Part of the static terminal 1 and the moving terminal 3 extends out of the housing 16 for easy connection to the external circuit.

[0073] The static terminal 1 is designed in an L shape. Such a design may be to optimize the space layout or facilitate installation and connection.

[0074] In summary, this double-circuit on-off relay realizes the precise control of the moving contact 4 and the static contact 2 through the mechanical transmission system driven by the motor 5, and ensures the stability and reliability of the contacts through the self-locking mechanism and the high-elasticity shrapnel assembly. This design not only improves the service life and working accuracy of the relay, but also reduces mechanical wear and noise level.

[0075] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the protection scope of the present utility model.
