Description

Technical Field

[0001] This utility model relates to the field of timer technology, and specifically to a timer connector. Background Technology

[0002] In modern family life, the use of various electrical appliances is becoming more and more frequent. Traditional electrical control methods mostly rely on manual operation by users to control the devices to turn on or off when needed.

[0003] However, for some devices that have long-term needs and are used and turned off at fixed times, such as pool pumps and pool lights in the summer, users need to turn them on and off at fixed times, which undoubtedly increases the repetitive work of users.

[0004] Furthermore, if users forget to turn off the power to their devices when they are not in use, it not only wastes electricity but may also shorten the lifespan of the equipment due to prolonged operation. Therefore, the market urgently needs a system that can automatically control the operating time of electrical equipment, reducing repetitive tasks for users, extending equipment lifespan, and minimizing energy waste. Utility Model Content

[0005] This utility model provides a timer connector to solve the problem that the operating time of electrical equipment cannot be automatically controlled in the prior art.

[0006] To achieve the above objectives, the present utility model adopts the following technical solution: a timing connector, including a carrier plate and a timing module, a connection module, a first transmission module and a second transmission module disposed on the carrier plate. The timing module includes a dial and a motor that drives the dial to rotate counterclockwise. At least one set of levers is disposed on the dial.

[0007] The connection module is located on the side of the carrier plate away from the dial. The connection module includes a first spring, a first stationary contact, and a first connecting shaft rotatably mounted on the carrier plate. A push plate is provided at the end of the first connecting shaft away from the carrier plate. The first spring is located on the rotation path of the push plate. A first moving contact is provided on the first spring at a position corresponding to the first stationary contact. The first moving contact and the first stationary contact are electrically connected to different terminals, which are electrically connected to an external circuit. In the normal state, the first stationary contact and the first moving contact are in contact. When the first connecting shaft drives the push plate to rotate counterclockwise and abut against the first spring, causing the first spring to bend, the first moving contact moves away from the surface of the first stationary contact. When the first connecting shaft drives the push plate to rotate clockwise and moves away from the surface of the first spring, the first spring returns to its normal state, and the first stationary contact and the first moving contact abut against each other.

[0008] When the dial rotates counterclockwise, the paddle group triggers the first transmission module, causing the first connecting shaft to rotate clockwise; when the paddle group moves close to the second transmission module, the paddle group triggers the second transmission module, causing the first connecting shaft to rotate counterclockwise.

[0009] Furthermore, the dial assembly includes a power-off dial and a power-on dial, which are detachably mounted on the dial according to the desired power-on time. The power-off dial has a power-off lever at its bottom, and the power-on dial has a power-on lever at its bottom.

[0010] Furthermore, the first transmission module includes a second connecting plate and a first connecting plate disposed on a support plate. The end of the first connecting shaft away from the push plate passes through the support plate and is fixedly connected to the center of the first connecting plate. A first snap-fit ​​hole is formed at the end of the first connecting plate near the second connecting plate. A snap-fit ​​block protruding into the first snap-fit ​​hole is formed on the first connecting plate, so that a first snap-fit ​​position and a second snap-fit ​​position are formed in the first snap-fit ​​hole. The center of the second connecting plate is disposed on the support plate through the second connecting shaft, and the second connecting shaft drives the second connecting plate to rotate on the support plate. A first abutment end is formed on the second connecting plate that can abut against the energized lever and drive the second connecting plate to rotate clockwise. A first contact end that moves in the first snap-fit ​​hole is disposed at the end of the second connecting plate near the first connecting plate. The first transmission module also includes a double torsion spring. One straight arm of the double torsion spring is disposed at the end of the second connecting plate away from the first connecting plate. The spring coil of the double torsion spring near the first connecting plate is sleeved on the first connecting shaft. The other straight arm of the double torsion spring is disposed at the end of the first connecting plate away from the second connecting plate. The other spring coil of the double torsion spring is sleeved on the second connecting shaft.

[0011] Furthermore, the second transmission module includes a third connecting plate, a fourth connecting plate, and a first fixed post mounted on the support plate. The third and fourth connecting plates are rotatably connected via a movable shaft. The third connecting plate is sleeved on the first connecting shaft. A first spring connects the first fixed post to the movable shaft. A second fixed post is mounted on the support plate and positioned along the rotation path of the third connecting plate. When the third connecting plate abuts against the second fixed post, the third connecting plate stops rotating counterclockwise. One end of the fourth connecting plate forms a baffle that allows the fourth connecting plate to hook onto the third connecting plate and rotate the third connecting plate clockwise. The baffle is also positioned along the rotation path of the power-off lever. The second fixed post and the first fixed post... A second spring connects the four connecting plates. When the power-off lever abuts against the baffle, the power-off lever causes the baffle and the fourth connecting plate to rotate clockwise, and the second spring is in a stretched state. The power-off lever continues to rotate until it leaves the surface of the baffle. At this point, the second spring causes the fourth connecting plate to rotate counterclockwise. The end of the fourth connecting plate away from the third abutment end has a movable end. The end of the third connecting plate near the third abutment end has a second abutment end that can abut against the power-off lever and cause the third connecting plate to rotate clockwise. The other end of the third connecting plate has a second locking hole that allows the movable end to move. The end of the first connecting plate away from the first locking hole has a slot for the movable end to be inserted.

[0012] Furthermore, the connection module also includes a second spring, one end of which is fixedly connected to the support plate. A second moving contact is provided at the end of the second spring away from the support plate. An insulating linkage plate is placed between the second spring and the first spring. The second spring is linked with the first spring according to the linkage plate. A second stationary contact is provided on the support plate at the position corresponding to the second moving contact. Both the second moving contact and the second stationary contact are electrically connected to different terminals, which are electrically connected to an external circuit. In the normal state, the second stationary contact and the second moving contact are in contact. When the first spring bends, it drives the linkage plate to move, causing the second spring to bend, thereby causing the second moving contact to leave the surface of the second stationary contact. When the first spring returns to its normal state, the second spring also returns to its normal state, and the second stationary contact and the second moving contact abut.

[0013] Furthermore, the timer connector is encased in a housing.

[0014] Furthermore, the housing includes an upper housing and a lower housing, with the upper housing rotatably connected to the lower housing via a connector.

[0015] Furthermore, handles are provided on the side of the first connecting plate and the second connecting plate away from the bearing plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] The timer connector provided by this utility model can be set with fixed switching times. By connecting to external electrical equipment, it can control the running time of the external electrical equipment, and can also control the operation of the external electrical equipment periodically, such as 24-hour cycle, 8-hour cycle or 12-hour cycle, thereby meeting the diverse needs of users.

[0028] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0029] like Figure 1-8 As shown, this utility model embodiment provides a timing connector, including a carrier plate 3 and a timing module 2, a connection module 6, a first transmission module 4, and a second transmission module 5 disposed on the carrier plate 3, as follows: Figure 6 As shown, with the side facing the support plate 3 where the transmission module 4 is provided as a view reference (the rotation mentioned below refers to counterclockwise rotation or counterclockwise rotation under this view reference), the timing module 2 includes a dial 21 and a motor 22 that drives the dial 21 to rotate counterclockwise. At least one set of paddles is provided on the dial 21.

[0030] The dial assembly includes a power-off dial 23 and a power-on dial 24. The power-off dial 23 and the power-on dial 24 are detachably mounted on the dial 21 according to the desired power-on time. (In one specific embodiment, the dial 21 rotates counterclockwise one full circle every 24 hours, the connector is set to power on for 12 hours, and the power-off dial 23 reaches the initial position of the power-on dial 24 after rotating counterclockwise half a circle (12 hours); in another specific embodiment, the dial 21 rotates counterclockwise one full circle every 24 hours, the connector is set to power on for 6 hours, and the power-off dial 23 reaches the initial position of the power-on dial 24 after rotating counterclockwise a quarter circle (6 hours). A power-off lever 231 is formed at the bottom of the power-off dial 23, and a power-on lever 241 is formed at the bottom of the power-on dial 24.)

[0031] The connecting module 6 is located on the side of the support plate 3 away from the dial 21. The connecting module 6 includes a first spring 61, a first stationary contact 62, and a first connecting shaft 63 rotatably mounted on the support plate 3. A push plate 64 is provided at the end of the first connecting shaft 63 away from the support plate 3. The first spring 61 is located on the rotation path of the push plate 64. A first moving contact 65 is provided on the first spring 61 at a position corresponding to the first stationary contact 62. The first moving contact 65 and the first stationary contact 62 are electrically connected to different terminals, which are electrically connected to an external circuit. In the normal state, the first stationary contact 62 and the first moving contact 65 abut against each other. The first connecting shaft 63 drives the push plate 64 to rotate clockwise and engage with the first spring 61. When the first contact 62 abuts and bends the first spring 61, the first moving contact 65 moves away from the surface of the first stationary contact 62; when the first connecting shaft 63 drives the push plate 64 to rotate counterclockwise and move away from the surface of the first spring 61, the first spring 61 returns to its normal state, and the first stationary contact 62 and the first moving contact 65 abut (in a specific embodiment, the two terminals are electrically connected to the input and output terminals of the neutral and live wires respectively through wires, and the neutral and live wires are electrically connected to the external electrical equipment, so that the neutral and live wires, the connector and the electrical equipment form a circuit loop. When the first stationary contact 62 and the first moving contact 65 abut, the circuit is closed and the electrical equipment is turned on; when the first moving contact 65 moves away from the surface of the first stationary contact 62, the circuit is broken and the electrical equipment is turned off).

[0032] The abutting end of the first transmission module 4 is located on the rotation path of the energizing lever 241. The dial 21 rotates counterclockwise. When the energizing lever 241 approaches the first transmission module, the energizing lever 241 drives the first connecting shaft 63 to rotate clockwise through the first transmission module 4, causing the push plate 64 to leave the surface of the first spring 61. The first spring 61 is in a straight line state, and the first stationary contact 62 abuts against the first moving contact 65. The abutting end of the second transmission module 5 is located on the rotation path of the de-energizing lever 231. When the de-energizing lever 231 approaches the second transmission module 5, the de-energizing lever 231 triggers the second transmission module 5. The second transmission module 5 cooperates with the first transmission module 4, causing the first transmission module 4 to drive the first connecting shaft 63 to rotate counterclockwise, causing the push plate 64 to abut against the first spring 61 and causing the first spring 61 to bend, separating the first stationary contact 62 from the first moving contact 65.

[0033] The first transmission module 4 includes a second connecting plate 41 and a first connecting plate 42 disposed on a support plate 3. The end of a first connecting shaft 63 away from the push plate 64 passes through the support plate 3 and is fixedly connected to the center of the first connecting plate 42. A first locking hole 43 is formed at the end of the first connecting plate 42 near the second connecting plate 41. A locking block 44 protruding into the first locking hole 43 is formed on the first connecting plate 42, creating a first locking position 431 and a second locking position 432 within the first locking hole 43. The center of the second connecting plate 41 is disposed on the support plate 3 via a second connecting shaft 45, and the second connecting shaft 45 drives the second connecting plate 41 to rotate on the support plate 3. The upper part has a first abutting end 411 that can abut against the energized lever 241 and drive the second connecting plate 41 to rotate clockwise. The second connecting plate 41 is provided with a first contact end 46 that moves in the first snap-fit ​​hole 43 at one end near the first connecting plate 42. The first transmission module 4 also includes a double torsion spring 47. One straight arm of the double torsion spring 47 is provided at the end of the second connecting plate 41 away from the first connecting plate 42. The spring coil of the double torsion spring 47 near the first connecting plate 42 is sleeved on the first connecting shaft 63. The other straight arm of the double torsion spring 47 is provided at the end of the first connecting plate 42 away from the second connecting plate 41. The other spring coil of the double torsion spring 47 is sleeved on the second connecting shaft 45.

[0034] When the energized lever 241 abuts against the first abutment end 411, thereby causing the second connecting plate 41 to rotate clockwise, the second connecting plate 41 exerts a clockwise rotation force on the straight arm of the double torsion spring 47 mounted on the second connecting plate 41, causing the spring coil of the double torsion spring 47 sleeved on the second connecting shaft 45 to rotate clockwise, causing the connecting section of the double torsion spring 47 to exert a counterclockwise rotation force on the spring coil sleeved on the first connecting shaft 63, causing the straight arm of the double torsion spring 47 mounted on the first connecting plate 42 to exert a counterclockwise rotation force on the first connecting plate 42, causing the first contact end 46 to move from the first locking position 431 to the second locking position 432 and be blocked by the locking block 44, preventing the first contact end 46 from returning to the second locking position 432, so that the push plate 64 no longer abuts against the first spring piece 61, the first spring piece 61 returns to its original state, and the first stationary contact 62 abuts against the first moving contact 65.

[0035] The second transmission module 5 includes a third connecting plate 51, a fourth connecting plate 52, and a first fixed post 53 disposed on the support plate 3. The third connecting plate 51 and the fourth connecting plate 52 are rotatably connected by a movable shaft 54. The third connecting plate 51 is sleeved on the first connecting shaft 63. A first spring 55 is connected between the first fixed post 53 and the movable shaft 54. When the third connecting plate 51 rotates clockwise around the first connecting shaft 63, the first spring 55 provides a spring force for the third connecting plate 51 to rotate counterclockwise around the movable shaft 54. A second fixed post 56 is disposed on the support plate 3 along the rotation path of the third connecting plate 51. When the third connecting plate 51 abuts against the second fixed post 56, the third connecting plate 51 stops rotating counterclockwise. One end of the fourth connecting plate 52 forms a baffle 58 for the fourth connecting plate 52 to hook the third connecting plate 51 and drive the third connecting plate 51 to rotate clockwise. The baffle 58 is also disposed on the power-off lever 2. On the rotation path of 31, a second spring 57 is connected between the second fixed post 56 and the fourth connecting plate 52. When the power-off lever 231 abuts against the baffle 58, the power-off lever 231 drives the baffle 58 and the fourth connecting plate 52 to rotate clockwise, and the second spring 57 is in a stretched state. The power-off lever 231 continues to rotate until it leaves the surface of the baffle 58, at which point the second spring 57 drives the fourth connecting plate 52 to rotate counterclockwise. The end of the fourth connecting plate 52 away from the third abutment end 521 forms a movable end 522. The end of the third connecting plate 51 close to the third abutment end 521 forms a second abutment end 511 that can abut against the power-off lever 231 and drive the third connecting plate 51 to rotate clockwise. The other end of the third connecting plate 51 forms a second locking hole 512 that allows the movable end 522 to move. The end of the first connecting plate 42 away from the first locking hole 43 forms a slot 48 for the movable end 522 to be inserted.

[0036] When the power-off lever 231 rotates to first contact the baffle 58 on the fourth connecting plate 52, the power-off lever 231 drives the fourth connecting plate 52 to rotate clockwise. At the same time, the baffle 58 hooks the third connecting plate 51, causing the fourth connecting plate 52 and the third connecting plate 51 to rotate clockwise simultaneously. The first spring 55 and the second spring 57 extend. After rotating a certain angle, the baffle 58 will first disengage from the power-off lever 231. At this time, the power-off lever 231 only abuts against the second abutting end 511 of the third connecting plate 51. The baffle 58 leaves the surface of the third connecting plate 51 and continues to drive the third connecting plate 51 to rotate. Meanwhile, after the fourth connecting plate 52 disengages from the power-off lever 231, the fourth connecting plate 52 is subjected to the contraction force of the second spring 57 and rotates counterclockwise around the movable shaft 54, causing the moving end 522 on the fourth connecting plate 52 to embed into the slot 48 on the first connecting plate 42.

[0037] The dial 21 continues to rotate. Before the second abutting end 511 of the third connecting plate 51 disengages from the power-off lever 231, the moving end 522 can move within the second locking hole 512, so the third connecting plate 51 will not drive the fourth connecting plate 52 to move, keeping the moving end 522 embedded in the slot 48 on the first connecting plate 42. After the second abutting end 511 disengages from the power-off lever 231, the first spring 55 contracts and drives the movable shaft 54 ​​to move, causing the third connecting plate 51 and the fourth connecting plate 52 to rotate counterclockwise around the first connecting shaft 63 simultaneously for reset. During the rotation, the moving end 522 on the fourth connecting plate 52 exerts a counterclockwise rotational force on the first connecting plate 42 through the slot 48. The connecting plate 42 rotates counterclockwise, causing the spring coil of the double torsion spring 47 sleeved on the first connecting plate 42 to rotate counterclockwise. The straight arm of the double torsion spring 47 on the first connecting plate 42 gives the first connecting plate 42 a force for clockwise rotation. The connecting section of the double torsion spring 47 and the straight arm on the second connecting plate 41 give the second connecting shaft 45 a force for clockwise rotation, causing the first contact end 46 to move from the second locking position 432 to the first locking position 431. During this process, the first connecting plate 42 drives the first connecting shaft 63 to rotate clockwise, causing the push plate 64 to rotate and abut against the first spring piece 61. The first spring piece 61 is squeezed and bends away from the push plate 64, causing the first moving contact 65 to leave the surface of the first stationary contact 62, thereby de-energizing the connector.

[0038] The third connecting plate 51 and the fourth connecting plate 52 drive the first connecting plate 42 to continue rotating counterclockwise. When the third connecting plate 51 abuts against the second fixed post 56, the third connecting plate 51 stops rotating, causing the fourth connecting plate 52 to continue rotating counterclockwise around the movable axis 54 and drive the first connecting plate 42. The moving end 522 of the fourth connecting plate 52 falls out of the slot 48 of the first connecting plate 42.

[0039] To enable the timing junction box to simultaneously connect to two external electrical devices, thereby controlling the simultaneous opening and closing of the two devices, in a preferred embodiment of this invention, the connection module 6 further includes a second spring 66. One end of the second spring 66 is fixedly connected to the support plate 3, and a second moving contact 67 is provided at the end of the second spring 66 away from the support plate 3. An insulating linkage plate 68 is provided between the second spring 66 and the first spring 61. The second spring 66 is linked with the first spring 61 according to the linkage plate 68. The second moving contact 67 is connected to the support plate 3. A second stationary contact 69 is provided at the position corresponding to contact 67. The second moving contact 67 and the second stationary contact 69 are electrically connected to different terminals. The terminals are electrically connected to an external circuit. In the normal state, the second stationary contact 69 and the second moving contact 67 are in contact with the second spring 66. When the first spring 61 bends, it drives the linkage plate 68 to move, causing the second spring 66 to bend, thereby causing the second moving contact 67 to leave the surface of the second stationary contact 69. When the first spring 61 returns to the normal state, the second spring 66 also returns to the normal state, and the second stationary contact 69 and the second moving contact 67 are in contact.

[0040] To prevent the second connecting plate 41, the first connecting plate 42, the third connecting plate 51, and the fourth connecting plate 52 from colliding with each other during rotation, in a preferred embodiment of this utility model, the second connecting plate 41, the first connecting plate 42, the third connecting plate 51, and the fourth connecting plate 52 are arranged in order from farthest to closest to the support plate 3, and the distance between the power-off lever 231 and the support plate 3 is greater than the distance between the power-on lever 241 and the support plate 3.

[0041] To prevent the connector from being corroded by rainwater and to increase the safety of the connector, in a preferred embodiment of this utility model, the timer connector is covered by a housing 1. In order to facilitate the maintenance of the connector, in a preferred embodiment of this utility model, the housing 1 includes an upper housing 11 and a lower housing 12, and the upper housing 11 is rotatably connected to the lower housing 12 through a connector 13.

[0042] To enhance the functionality of the connector and enable manual reset, in a preferred embodiment of this invention, a handle is provided on the side of the first connecting plate 42 and the second connecting plate 41 away from the support plate 3. The handle is used to manually rotate the first connecting plate 42 and the second connecting plate 41.

[0043] This timer connector can be set with fixed switching times. By connecting to external electrical equipment, it can control the operating time of the external electrical equipment. It can also control the operation of the external electrical equipment periodically, such as in 24-hour, 8-hour, or 12-hour cycles, thereby meeting the diverse needs of users.

[0044] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
