Description

Technical Field

[0001] This invention relates to the field of electrical equipment, and more particularly to a cam-type bidirectional signal conversion connector and its device. Background Technology

[0002] Bidirectional signal converters, also known as bidirectional signal transducers or bidirectional level converters, are key components in modern electronic systems that connect different signal domains. They can convert signal formats, voltage levels, or transmission media in two directions, combining signal conversion and connection functions. By bridging two conductors in a circuit, they enable bidirectional transmission of current and signals between different conductors. They are core foundational components in industrial control, communication networks, embedded development, and other fields. In practical applications, the plug-in / plug-out accuracy, mating stability, and operational efficiency of bidirectional signal converters directly determine the reliability of signal transmission. Therefore, high requirements are placed on the linkage, locking, and ease of use of their plug-in / plug-out structure.

[0003] The insertion and removal of plugs in existing bidirectional signal conversion connectors mostly rely on manual operation to switch signals. This is not only inefficient and unsuitable for frequent switching scenarios, but also makes it difficult to ensure precise alignment between the plug and the conductor connection during manual insertion and removal, which can easily lead to insertion deviations and affect the stability of signal transmission. At the same time, the existing plug and connector body mating structure lacks a reliable locking design. When the device is subjected to accidental collisions or vibrations, the plug is very likely to loosen and separate from the conductor connection, resulting in signal transmission interruption and failure to complete normal bidirectional signal conversion.

[0004] To address these issues, some bidirectional signal conversion connectors have attempted to add simple transmission structures to assist in insertion and removal. However, the linkage design between the operating components and the plug in such structures is not rational enough, and the matching accuracy between the transmission components and the drive components is low. This can easily lead to problems such as plug movement jamming and inaccurate control of extension and retraction stroke. Furthermore, the locking state of the operating components and the matching of the reset structure are not smooth. After unlocking, the reset drive force can easily cause the transmission components to lose control of their return position, resulting in a deviation in the reset of the operating components. This, in turn, affects the precise docking of the plug and the conductor connection. It still cannot solve the core requirements of low insertion and removal accuracy, unreliable locking, and adaptability to frequently switching scenarios.

[0005] Therefore, there is an urgent need to develop a plug-in / plug-out drive structure adapted to bidirectional signal conversion connectors. This structure uses a control handle to link the transmission components, achieving precise driving and stable locking of the plug while ensuring the orderly reset of each component after unlocking. This would solve the technical problems of existing bidirectional signal conversion connectors, such as low manual plug-in / plug-out efficiency, inaccurate mating, lack of reliable locking, and difficulty in adapting to frequent switching scenarios, thereby improving the plug-in / plug-out reliability and ease of use of bidirectional signal conversion connectors. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned problems, thereby providing a cam-type bidirectional signal conversion connector and its device. The present invention replaces the traditional manual plugging and unplugging operation, greatly simplifies the signal conversion steps, and significantly improves the efficiency of use in frequent switching scenarios; through multiple structural optimizations, the stability and reliability of the connection are guaranteed; and it provides an efficient, reliable and safe solution for bidirectional signal conversion.

[0007] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A cam-type bidirectional signal conversion connector includes a housing, with receiving portions provided on the left and right sides of the housing, the receiving portions being placed in the internal cavity of the housing, a portion of the motion shaft and an elastic component being placed in the receiving portion, and a plug being disposed on the first end face of the motion shaft; A transmission assembly is placed inside the internal cavity of the housing, and the transmission assembly is provided with a cam having a smooth curved surface; A control handle, connected to a slider, is used to control the slider to move horizontally, and the slider engages with the transmission assembly; When the operating handle moves to the left or right from its initial position, the transmission assembly rotates axially to offset the cam. The cam abuts against the target motion shaft partially placed in the target receiving portion, causing the target plug located at the first end face of the target motion shaft to move in a first direction. The target plug extends out of the target receiving portion, and the target elastic component placed in the target receiving portion deforms. When the control handle is moved to its limit position, the control handle is locked, and the target plug extends out of the housing to be plugged into or unplugged from external devices. When the control handle switches from the locked state to the active state, the target elastic component gradually returns to its initial state, so that the target plug moves in the second direction, the cam returns from the biased state to its initial state, and the transmission component moves axially, so that the control handle returns to its initial state.

[0008] As a preferred embodiment, a further technical solution of the present invention is as follows: Furthermore, the transmission assembly includes a central shaft placed in the internal cavity of the housing and a gear passing through the central shaft, and the direction of the central shaft is a third direction; The slider is placed inside the housing on a horizontally positioned guide rail. A rack is provided on the upper surface of the slider, and the rack meshes with the gear.

[0009] Furthermore, the first end of the control handle is hinged to the front and rear side surfaces of the slider, and a connecting rod is hinged to the side of the external device near the control handle. The other end of the connecting rod is hinged to the middle of the control handle. The control handle, the connecting rod and the slider together form a crank-slider mechanism, which is used to convert the reciprocating swing of the control handle into the horizontal movement of the slider.

[0010] Furthermore, the left and right side surfaces of the slider are hinged with a first locking component, and the left and right sides of the housing are provided with a second locking component, which is located inside the housing. When the operating handle moves to the left or right to its limit position, the first locking component and the second locking component engage with each other to lock the operating handle in the locked state.

[0011] Furthermore, it also includes: a knob, which is disposed on the front surface of the housing and connected to a rotating shaft disposed in a third direction inside the housing; A paddle, passing through the pivot, is located near the first locking component and above the side of the first locking component. The operating handle is locked in the locked state, and the paddle is arranged in a horizontal direction. When the control handle is locked in the locked state, rotating the knob causes the rotating shaft to move axially in a third direction, causing the paddle to rotate. The paddle contacts the first locking component, and the first locking component moves downward under the pressure of the paddle, causing the first locking component and the second locking component to disengage from their latching state. The control handle then returns to the moving state from the locked state.

[0012] Furthermore, a third elastic member is provided on the lower surface of the outer shell, the end of which is a free end, and the free end abuts against the first locking member.

[0013] Furthermore, the motion shaft is provided with protrusions surrounding the shaft body, and the elastic component includes: a first elastic component and a second elastic component; The first elastic member is positioned between the protrusion and the second end face of the receiving portion; The second elastic member is positioned between the protrusion and the inner wall of the outer casing.

[0014] Furthermore, a spring sheet is provided around the first end face of the plug, and the external device is provided with a slot corresponding to the spring sheet. When the operating handle is moved to the limit position, the spring sheet is placed in the slot to realize the plug-in and plug-out connection between the plug and the external device.

[0015] Furthermore, the third end face of the motion shaft is provided with an arc-shaped protrusion, and the arc-shaped surface of the cam abuts against the arc-shaped protrusion.

[0016] A cam-type bidirectional signal conversion connection device includes a cam-type bidirectional signal conversion connector and external devices disposed on the left and right sides of the cam-type bidirectional signal conversion connector.

[0017] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: 1. This invention addresses the pain points of existing technologies, which require manual plugging and unplugging and have low conversion efficiency. Through innovative mechanical structure design, it achieves automation and convenience in signal conversion. Simply turning the control handle moves the slider through the cooperation of the slider and guide rail. Then, through the external meshing of the rack and pinion, the cam rotates synchronously, ultimately pushing the plug to precisely extend and retract, completing the bidirectional device connection. This integrated transmission design replaces the traditional manual plugging and unplugging operation, greatly simplifying the signal conversion steps. At the same time, the connection and unlocking logic of the left and right ends are completely consistent, reducing the learning cost of operation and significantly improving the efficiency of use in scenarios with frequent switching. 2. This invention ensures the stability and reliability of the connection through multiple structural optimizations. The plug has four evenly distributed spring plates on its periphery, which fit tightly into the preset slots when inserted into the device. This strengthens the connection's firmness through elasticity and also acts as a guide to ensure precise alignment. The locking device between the slider and the outer shell provides secondary protection. After the slider moves into position, the first locking component automatically engages through the elastic force of the third elastic component, effectively preventing connection separation caused by accidental collisions or vibrations. Furthermore, the elastic component provides buffering through expansion and contraction during plug movement, reducing hard contact wear. Simultaneously, the elastic force drives the plug to precisely reset during unlocking, further enhancing the stability of the mechanism's operation. 3. The overall design of this invention combines practicality and safety, and is suitable for various electrical equipment scenarios. The outer shell encapsulates the core transmission components and electrical connection structure, effectively isolating external interference such as dust and moisture, and reducing the risk of component damage. The linkage design for unlocking and switching requires unlocking via the paddle before operating the control handle, avoiding accidental disconnection due to accidental touch and ensuring safe use. The modular structural layout makes the transmission path of each component clear and reduces losses. Combined with wear-resistant elastic components such as spring plates and third elastic components, it extends the service life of the equipment and provides an efficient, reliable, and safe solution for bidirectional signal conversion.

[0019] The following description of the embodiments will help the public better understand the present invention. However, the specific embodiments provided by the applicant should not and should not be regarded as a limitation on the technical solution of the present invention. Any changes to the definition of components or technical features and / or formal but not substantive changes to the overall structure should be regarded as the scope of protection defined by the technical solution of the present invention.

[0020] The technical solution of this invention is as follows: like Figures 1-5 As shown, a cam-type bidirectional signal conversion connector includes a housing 1, a transmission component, and an operating handle 7.

[0021] In this application, the outer casing 1 is made of an insulating and wear-resistant material, which improves the insulation performance and extends the service life.

[0022] Meanwhile, the outer shell 1 is a hollow structure, and receiving portions 2 are respectively provided on the left and right sides of the outer shell 1; In this application, for ease of description, when the operating handle 7 moves to the left or right, the receiving part 2, the motion shaft 5, the plug 3 and the elastic component on the side corresponding to the direction of movement are selected as the target receiving part, the target motion shaft, the target plug and the target elastic component, while the other side remains in its initial state.

[0023] Reference Figure 1As shown, the receiving part 2 is placed in the internal cavity 4 of the outer shell 1. In this application, the receiving part 2 is provided with a portion of the motion shaft 5 and an elastic component, and the plug 3 is provided on the first end face of the motion shaft 5.

[0024] Reference Figure 1 , Figure 5 As shown, one possible approach is to provide a guide hole that extends horizontally through the receiving part 2, with the motion shaft 5 installed in the guide hole and both ends of the motion shaft 5 protruding from the receiving part 2. The guide hole provides guidance for the motion shaft 5 and the plug 3, thereby improving the accuracy of the plug 3's connection with the external device 24. In this application, the transmission component is placed in the internal cavity 4 of the housing 1, and the transmission component is provided with a cam 6 with a smooth curved surface; the inner wall of the housing 1 and the contact surface of each transmission component are coated with a lubricating layer, which not only ensures electrical safety, but also reduces frictional loss during component movement and extends service life.

[0025] The operating handle 7 is connected to the slider 8 and is used to control the slider 8 to move in the horizontal direction. The slider 8 is engaged with the transmission component. The cooperation of the operating handle 7, the slider 8 and the transmission component improves the insertion and removal efficiency of the plug 3 to adapt to frequently switching usage scenarios. When the operating handle 7 moves to the left or right from the initial position, the transmission component rotates axially to offset the cam 6. The cam 6 abuts against the target motion shaft 5, which is partially placed in the target receiving part 2, so that the target plug 3 located at the first end face of the target motion shaft 5 moves in the first direction. The target plug 3 extends out of the target receiving part 2, and the target elastic component placed in the target receiving part 2 deforms. When the control handle 7 is moved to its limit position, the control handle 7 is locked, and the target plug 3 extends out of the housing 1 and is plugged into or unplugged from the external device 24. When the control handle 7 switches from the locked state to the active state, the target elastic component gradually returns to its initial state, so that the target plug 3 moves in the second direction, the cam 6 returns from the biased state to its initial state, and the transmission component moves axially, so that the control handle 7 returns to its initial state.

[0026] It should be noted that the first direction is the direction that extends horizontally from the receiving part 2 to the outer shell 1, while the second direction is the opposite direction of the first direction. The above arrangement enables the motion shaft 5 to reciprocate along the guide hole, thereby enabling the motion shaft 5 to drive the plug 3 to be plugged in and out of the external device 24.

[0027] like Figure 5 , Figure 6As shown, the transmission components in this application will be described in detail below: In this application, the transmission assembly includes a central shaft 9 placed in the internal cavity 4 of the housing 1 and a gear 10 passing through the central shaft 9. The gear 10 and the central shaft 9 are rigidly connected, and the direction of the central shaft 9 is a third direction. It should be noted that the third direction points from the front surface of the housing 1 to the rear surface of the housing 1, and the third direction is parallel to the setting direction of the external device 24; The slider 8 is placed inside the housing 1 and on the horizontally positioned guide rail 11. A rack 12 is provided on the upper surface of the slider 8, and the rack 12 meshes with the gear 10. A groove is provided at the bottom of the slider 8, and the slider 8 is slidably connected to the guide rail 11 through the groove, thereby driving the slider 8 to achieve reciprocating linear motion along the guide rail 11, thereby causing the gear 10 to drive the central shaft 9 and the cam 6 to rotate.

[0028] like Figure 1 As shown, the first end of the control handle 7 is hinged to the front and rear side surfaces of the slider 8. A connecting rod 13 is hinged to the side of the external device 24 near the control handle 7. The other end of the connecting rod 13 is hinged to the middle of the control handle 7. The control handle 7, the connecting rod 13 and the slider 8 together form a crank-slider mechanism, which is used to convert the reciprocating swing of the control handle 7 into the horizontal movement of the slider 8.

[0029] like Figure 1 As shown, the left and right side surfaces of the slider 8 are hinged with a first locking component 14, and the left and right sides of the housing 1 are provided with a second locking component 15, which is located inside the housing 1. When the operating handle 7 moves to the left or right to its limit position, the first locking component 14 and the second locking component 15 engage with each other to lock the operating handle 7 in the locked state. The engagement of the first locking component 14 and the second locking component 15 improves the stability of the connection between the plug 3 and the external device 24, thereby achieving reliable locking.

[0030] To switch the control handle 7 from the locked state to the active state, refer to... Figure 4 and Figure 7 As shown, in a preferred embodiment, the front surface of the outer casing 1 is provided with a knob 16 and connected to a rotating shaft 17, while a paddle 18 is provided through the rotating shaft 17.

[0031] It should be noted that the direction of the rotating shaft 17 is a third direction, and the rotating shaft 17 is located inside the outer casing 1.

[0032] The paddle 18 is close to the first locking component 14 and located above and to the side of the first locking component 14. The operating handle 7 is locked in the locked state, and the paddle 18 is arranged in the horizontal direction. When the operating handle 7 is locked in the locked state, rotating the knob 16 causes the rotating shaft 17 to move axially in a third direction, causing the paddle 18 to rotate. The paddle 18 contacts the first locking component 14, and the first locking component 14 moves downward under the pressure of the paddle 18, so that the latch between the first locking component 14 and the second locking component 15 is released, and the operating handle 7 returns to the moving state from the locked state.

[0033] like Figure 4 As shown, a third elastic member 19 is provided on the lower surface of the outer shell 1. The end of the third elastic member 19 is a free end, which abuts against the first locking member 14. In the initial state, the third elastic member 19 is not compressed, and the third elastic member 19 is a locking spring. The elastic force of the third elastic member 19 pushes the first locking member 14 upward to achieve engagement with the second locking member 15.

[0034] like Figure 1 , Figure 6 As shown, the motion shaft 5 is provided with a protrusion 21 surrounding the shaft body, and the elastic component includes: a first elastic component 20 and a second elastic component 22; The first elastic member 20 is placed between the protrusion 21 and the second end face of the receiving portion 2, while the second elastic member 22 is placed between the protrusion 21 and the inner wall of the outer shell 1; In the initial state, the compression of the first elastic component 20 and the second elastic component 22 is the same; the sum of the elastic forces of the elastic components is greater than the elastic force of the spring sheet 23. After unlocking, the gear 10 drives the cam 6 to rotate in the opposite direction to reset, and at the same time, the elastic components drive the target plug 3 to return to the initial position through elastic reset; the first elastic component 20 and the second elastic component 22 are both reset springs, thus the elastic components effectively ensure the orderly reset of the plug 3.

[0035] like Figure 8 As shown, a spring sheet 23 is provided around the plug 3 on the first end face, and the external device 24 is provided with a slot corresponding to the spring sheet 23. When the operating handle 7 moves to the limit position, the spring sheet 23 is placed in the slot to realize the plug-in connection between the plug 3 and the external device 24. The spring sheet 23 has elastic deformation capability. When the target plug 3 is inserted into the external device 24, the spring sheet 23 engages with the corresponding slot of the external device 24 to achieve a firm connection between the target plug 3 and the external device 24. The spring sheet 23 also has a guiding function.

[0036] like Figure 2 As shown, the third end face of the motion shaft 5 is provided with an arc-shaped protrusion 25, which is semi-circular. The arc-shaped surface of the cam 6 abuts against the arc-shaped protrusion 25. The cam 6 has a teardrop-shaped structure, and the arc-shaped surface of the cam 6 is adapted to the arc-shaped protrusion 25 of the motion shaft 5 to ensure that the cam 6 can smoothly drive the plug 3 to perform linear reciprocating motion when rotating, and there is no jamming during the transmission process.

[0037] like Figure 7 , 9 As shown, a cam-type bidirectional signal conversion connection device includes the aforementioned cam-type bidirectional signal conversion connector; and external devices 24 disposed on the left and right sides of the aforementioned cam-type bidirectional signal conversion connector.

[0038] The beneficial technical effects of this invention are: 1. This invention addresses the pain points of existing technologies, which require manual plugging and unplugging and have low conversion efficiency. Through innovative mechanical structure design, it achieves automation and convenience in signal conversion. Simply rotating the control handle 7 moves the slider 8 through the cooperation of the slider 8 and the guide rail 11. Then, through the external meshing transmission of the rack 12 and the gear 10, the cam 6 rotates synchronously, ultimately pushing the plug 3 to precisely extend and retract, completing the bidirectional device connection. This integrated transmission design replaces the traditional manual plugging and unplugging operation, greatly simplifying the signal conversion steps. At the same time, the connection and unlocking logic of the left and right ends are completely consistent, reducing the learning cost of operation and significantly improving the efficiency of use in frequently switching scenarios. 2. This invention ensures the stability and reliability of the connection through multiple structural optimizations; the plug 3 is provided with four evenly distributed spring plates 23 on its periphery, which can fit tightly with the preset slot when inserted into the device, which not only strengthens the connection with elastic force, but also plays a guiding role to ensure accurate positioning; the locking device between the slider 8 and the outer shell 1 forms a secondary protection. After the slider 8 moves into place, the first locking component 14 automatically hooks in through the elastic force of the third elastic component 19, effectively avoiding connection separation caused by accidental collision or vibration; in addition, the elastic component achieves buffering through expansion and contraction deformation during the movement of the plug 3, reducing hard contact wear, and at the same time, it drives the plug 3 to accurately reset with elastic force when unlocking, further improving the stability of the mechanism operation; 3. The overall design of this invention combines practicality and safety, and is suitable for various electrical equipment scenarios. The outer shell 1 encapsulates the core transmission components and electrical connection structure, effectively isolating external interference such as dust and moisture, and reducing the risk of component damage. The linkage design for unlocking and switching requires unlocking via the paddle 18 before operating the control handle 7, avoiding accidental disconnection due to accidental touch and ensuring safe use. The modular structural layout makes the transmission path of each component clear and reduces losses. Combined with wear-resistant elastic components such as the spring plate 23 and the third elastic component 19, it extends the service life of the equipment and provides an efficient, reliable, and safe solution for bidirectional signal conversion.
