[0002] A connector is a device that indirectly connects one object to another. Switch connectors are devices used to connect switch-related equipment. Rotary switches are very common in household appliances such as water heaters, fans, and microwave ovens. The knob of a rotary switch is connected to the rotating post of the switch body to realize the function of operating the switch by rotating the knob.
[0003] Problems with existing technology:
[0004] Existing switch connectors with holes are mostly integrally molded structures, which results in poor stability of the connection between the knob and the rotary switch and makes it inconvenient to disassemble and maintain them. Utility Model Content
[0005] The purpose of this utility model is to provide a connector with holes for switches, which can solve the problem that most existing connectors with holes for switches are integrally formed structures, resulting in poor stability when connecting knobs and rotary switches, and making it inconvenient to disassemble and maintain them.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A connector with a hole for a switch includes a PCB board body. A rotary switch body is installed on the left end of the PCB board body. A connecting sleeve is installed on the left end of the rotary switch body. The connecting sleeve is engaged with a transmission connection mechanism through a limiting hole on its upper side and two guide grooves. A knob mechanism is provided on the left end of the transmission connection mechanism.
[0008] The transmission connection mechanism includes a transmission rod body, which is connected to a connecting sleeve with two guide blocks on its upper right end and two guide grooves inside.
[0009] The transmission rod body has a storage groove inside on the right side. The bottom surface of the storage groove is fixedly connected to the lower end of the first spring. The upper end of the first spring is fixedly connected to a limiting block. The upper end of the limiting block is engaged with a connecting sleeve with a limiting hole on the upper side inside. The limiting block is slidably connected to the storage groove.
[0010] The transmission rod body is inserted into the knob mechanism through a slot opened inside its left end. Limiting blocks are connected to both the upper and lower sides of the slot. Both limiting blocks are engaged with the knob mechanism through slots opened inside their relatively close ends.
[0011] The knob mechanism includes a plug-in block, which is plugged into the transmission rod body with a plug-in groove on the left end. The plug-in block is engaged with two limit blocks through limit grooves on both its upper and lower ends. The plug-in block has a square groove inside.
[0012] A push plate is slidably connected inside the square groove. The right end of the push plate is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly connected to the right side of the inside of the square groove. Two trapezoidal push blocks are fixedly connected to the right end of the push plate.
[0013] The upper sides of the two trapezoidal push blocks 1 overlap with the lower sides of the two trapezoidal push blocks 2 respectively. The relatively far ends of the two trapezoidal push blocks 2 are fixedly connected with locking blocks. The relatively far ends of the two locking blocks pass through the upper and lower ends of the square groove and are respectively locked with two limiting blocks, each with a locking groove inside.
[0014] Both ends of the two trapezoidal push blocks are fixedly connected to connecting plates. The four connecting plates are paired up and slidably connected to the four vertical rods through two circular through holes in their interiors.
[0015] The upper and lower ends of the four vertical rods are respectively fixedly connected to the upper and lower sides of the inside of the square groove. Springs are sleeved on the upper and lower sides of the four vertical rods. The relatively close ends of the eight springs are respectively fixedly connected to the four connecting plates. The relatively far ends of the eight springs are respectively fixedly connected to the upper and lower sides of the inside of the square groove. The left and right ends of the push plate are fitted with adjusting bolts of the push block.
[0016] The adjusting bolt is threadedly connected to the plug block with a threaded hole inside on the left end. The left end of the plug block is fixedly connected to the knob body, and the knob body has a circular through hole for the adjusting bolt to pass through. The right end of the knob body overlaps with the left end of the transmission rod body.
[0017] The technical effects achieved by this utility model are as follows:
[0018] This invention utilizes a set of limiting blocks, limiting grooves, insertion grooves, and the mutual cooperation between the insertion blocks to quickly connect the knob body and the transmission rod body. Then, with the mutual cooperation of the setting of adjusting bolts, push plates, trapezoidal push blocks one and two, vertical rods, springs two and three, and connecting plates, two locking blocks can be driven to pass through the upper and lower ends of the square groove until they engage with the two limiting blocks. This increases the stability of the connection between the knob body and the transmission rod body. Then, by rotating the knob body, with the cooperation of the transmission rod body and the connecting sleeve, the rotary switch body can be opened and closed. The mutual cooperation of the setting of guide blocks and guide grooves restricts the connection position between the rotating rod body and the connecting sleeve. Finally, the mutual cooperation of spring one, limiting top block, and limiting hole increases the stability of the connection between the rotating rod body and the connecting sleeve.

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0029] like Figure 1-7 As shown, a connector with a hole in a switch includes a PCB board body 5. A rotary switch body 4 is installed on the left end of the PCB board body 5. A connecting sleeve 3 is installed on the left end of the rotary switch body 4. The connecting sleeve 3 is connected to two guide grooves 6 through a limiting hole 7 on its upper side and is engaged with a transmission connection mechanism 2. A knob mechanism 1 is provided on the left end of the transmission connection mechanism 2. Through the mutual cooperation between the knob mechanism 1, the transmission connection mechanism 2 and the connecting sleeve 3, a stable rotation effect can be achieved to drive the rotary switch body 4 during use. The knob mechanism 1 and the transmission connection mechanism 2 can be easily disassembled, so that when one of the components is damaged, it can be easily disassembled and maintained. It also increases the convenience of the assembly process of the device.
[0030] Furthermore, the transmission connection mechanism 2 includes a transmission rod body 21. The transmission rod body 21 is connected to a connecting sleeve 3 with two guide blocks 23 on its upper right side and two guide grooves 6 inside. A storage groove 27 is provided inside the right side of the transmission rod body 21. The bottom surface of the storage groove 27 is fixedly connected to the lower end of the spring 26. A limit block 24 is fixedly connected to the upper end of the spring 26. The upper end of the limit block 24 is connected to the connecting sleeve 3 with a limit hole 7 on its upper inner side. The limit block 24 is slidably connected to the storage groove 27. The mutual cooperation between the guide blocks 23 and the guide grooves 6 can limit the connection position between the transmission rod body 21 and the connecting sleeve 3. Then, the spring 26, The mutual cooperation between the limiting top block 24 and the limiting hole 7 can increase the stability of the connection between the transmission rod body 21 and the connecting sleeve 3. The transmission rod body 21 is inserted into the knob mechanism 1 through the insertion groove 25 opened inside its left end. The upper and lower sides of the insertion groove 25 are connected to the limiting blocks 22. The two limiting blocks 22 are engaged with the knob mechanism 1 through the slots opened inside their relatively close ends. The mutual cooperation between the limiting blocks 22 and the insertion groove 25 can quickly achieve the connection process between the transmission rod body 21 and the knob mechanism 1, and can ensure the stability of the connection process between the transmission rod body 21 and the knob mechanism 1. Furthermore, it can quickly achieve the disassembly process when the device needs to be repaired or replaced.
[0031] Furthermore, the knob mechanism 1 includes a plug-in block 13, which plugs into the transmission rod body 21, which has a plug-in groove 25 inside its left end. The plug-in block 13 is engaged with two limit blocks 22 through limit grooves 112 opened inside its upper and lower ends. A square groove 14 is opened inside the plug-in block 13, and a push plate 15 is slidably connected inside the square groove 14. The right end of the push plate 15 is fixedly connected to one end of a second spring 17, and the other end of the second spring 17 is fixedly connected to the right side inside the square groove 14. Through the mutual cooperation between the plug-in block 13, the plug-in groove 25, the limit blocks 22, and the limit groove 112, the knob body 11 and the transmission rod body 21 can be connected. The connection position serves as a limitation. Then, with the cooperation of the set locking block 111 and the limiting block 22, the connection and fixation process between the knob body 11 and the transmission rod body 21 can be achieved. At this time, by rotating the knob body 11, the rotation opening and closing process of the rotary switch body 4 can be achieved under the action of the set transmission rod body 21 and the connecting sleeve 3. The right end of the push plate 15 is fixedly connected to two trapezoidal push blocks 110. The upper side of the two trapezoidal push blocks 110 overlaps with the lower side of the two trapezoidal push blocks 19 respectively. The relatively far ends of the two trapezoidal push blocks 19 are fixedly connected to locking blocks 111. The relatively far ends of the two locking blocks 111 pass through the upper and lower ends of the square groove 14 respectively. Each of the four vertical rods 18 is connected to a limit block 22, which has a slot inside. The front and rear ends of the two trapezoidal push blocks 19 are fixedly connected to connecting plates 16. The four connecting plates 16 are paired and slidably connected to the four vertical rods 18 through two circular through holes inside each plate. The upper and lower ends of the four vertical rods 18 are fixedly connected to the upper and lower sides of the square groove 14. Springs 113 are sleeved on the upper and lower sides of the four vertical rods 18. The left and right ends of the push plate 15 are connected to adjusting bolts 12 for the push block. The adjusting bolts 12 are threadedly connected to a plug-in block 13 with a threaded hole inside on the left end. A knob body 11 is fixedly connected to the left end of the plug-in block 13. The interior has a circular through hole for the adjusting bolt 12 to pass through. By using a cross-shaped screwdriver to rotate the adjusting bolt 12, the right end of the adjusting bolt 12 can be moved to the left. At this time, under the action of the second spring 17, the push plate 15 can be pushed to slide to the left inside the square groove 14. Then, with the cooperation of the third spring 113, the vertical rod 18 and the connecting plate 16, the two locking blocks 111 can be moved closer to each other, so that the two locking blocks 111 are no longer locked with the two limiting blocks 22. At this time, the plug block 13 can be easily removed from the inside of the plug groove 25, thereby achieving the separation effect between the knob body 11 and the transmission rod body 21.
[0032] The working principle of this utility model is as follows:
[0033] During the assembly of this device, firstly, the limiting top block 24 is pressed into the receiving groove 27. Then, through the cooperation of the guide block 23 and the guide groove 6, the right end of the transmission rod body 21 is inserted into the connecting sleeve 3. When the receiving groove 27 corresponds to the limiting hole 7, the limiting top block 24 can be automatically pushed into the limiting hole 7 under the action of the spring 26, thereby achieving the connection and installation process between the transmission rod body 21 and the connecting sleeve 3. Next, through the cooperation of the limiting block 22 and the limiting groove 112, the insertion block 13 is inserted into the insertion groove 25. Then, the adjusting screw is driven by a cross screwdriver. The bolt 12 rotates, and under the action of the push block at its right end, it can push the push plate 15 to slide to the right inside the square groove 14. During this process, with the cooperation of the trapezoidal push block 110, trapezoidal push block 29, vertical rod 18, spring 3 113 and connecting plate 16, the two locking blocks 111 can be driven to pass through the upper and lower ends of the square groove 14 until they are engaged with the two limiting blocks 22. At this time, the assembly process of the device can be completed. Afterwards, by rotating the knob body 11, with the cooperation of the transmission rod body 21 and the connecting sleeve 3, the rotary switch body 4 can be rotated to open and close.
[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
