Description

Technical Field

[0001] This invention relates to a pluggable connector, and more particularly to a high-voltage energy storage quick-connect connector. Background Technology

[0002] Plug-and-play connectors connect via a plug and a socket, allowing the metal clips inside the plug to elastically clamp and conduct electrical signals between the pins in the socket. To maintain a tight connection after plug and socket are inserted, a raised ring-shaped mounting bracket is typically installed on the outer wall of the socket. The plug has a cantilevered, elastic hook on its side wall. When the socket and its mounting bracket are inserted into the annular slot of the plug, the elastic hook on the plug's side wall engages with the mounting bracket on the outer wall of the socket, securing the connection and preventing the plug and socket from loosening due to vibration or accidental contact. When the plug and socket need to be separated, the elastic hook needs to be moved to disengage from the mounting bracket on the outer wall of the socket.

[0003] Existing elastic hooks are usually designed as a seesaw structure. By pressing the operating end of the elastic hook located at the fulcrum opposite the hook body, the elastic hook can swing at a certain angle, thereby separating the hook body from the hanging platform.

[0004] This type of elastic snap-on release structure has the following drawbacks:

[0005] 1. The operating end of the elastic hook is easily pressed by mistake (wires or other devices), which makes it impossible for the head to fit effectively and stably, and the plug and socket may come loose on their own, affecting the normal and stable transmission of electrical signals.

[0006] 2. When a sufficiently large pulling force is applied to the plug, it will cause the cantilever structure of the elastic hook to deform, which in turn will cause the hook body of the elastic hook to separate from the socket mounting plate, causing the plug and socket to separate, which in turn will cause the lock between the plug and socket to be released, resulting in poor locking stability after the plug and socket are plugged in. Summary of the Invention

[0007] To overcome the above-mentioned defects, the present invention provides a high-voltage energy storage quick-connect connector, which can prevent accidental pressing from causing the plug and socket to become loose, while enhancing the locking and retaining force between the plug and socket.

[0008] The technical solution adopted by this invention to solve its technical problem is as follows: a high-voltage energy storage quick-connect connector, including a socket and a plug. The outer circumference of the socket has a mounting platform with a convex ring structure or a groove structure. The inner side of the plug is provided with an annular slot. The socket and its mounting platform can be inserted into the annular slot of the plug. The side wall of the annular slot of the plug is provided with an elastic hook with a cantilever structure. The cantilever structure of the elastic hook extends along the axial direction of the plug in a free state. The hook body at the free end of the elastic hook can hook onto the stepped surface of the mounting platform facing away from the plug. An operating handle is provided on the elastic hook to stop along its elastic deformation direction. The operating handle can be connected to the plug to stop in the elastic deformation direction of the elastic hook.

[0009] As a further improvement of the present invention, the operating handle is installed on the cantilever structure of the elastic hook by sliding a set distance along the extension direction of the elastic hook cantilever structure. A radially protruding handle limiting block is provided on the outer circumferential wall of the plug. The handle limiting block is provided with a limiting slot extending along the axial direction of the plug. One end of the operating handle along its sliding direction can be inserted into the limiting slot.

[0010] As a further improvement of the present invention, the operating handle is provided with a first protrusion on one side wall along its sliding direction, and the limiting slot is provided with a second protrusion on its side wall. The second protrusion can generate interference force with the first protrusion in the relative sliding direction.

[0011] As a further improvement of the present invention, a sliding sleeve structure is formed on the operating handle, the sliding sleeve structure is slidably sleeved on the outside of the elastic buckle cantilever structure, a limiting protrusion is also provided on the side wall of the cantilever structure of the elastic buckle, and a long strip-shaped limiting groove is provided on the side wall of the operating handle along its sliding direction relative to the elastic buckle, the limiting protrusion is slidably inserted into the long strip-shaped limiting groove, and the limiting protrusion stops on the two side walls of the long strip-shaped limiting groove along its length direction.

[0012] As a further improvement of the present invention, the outer wall of the plug is provided with a first handle positioning groove and a second handle positioning groove arranged at intervals along the sliding direction of the operating handle, and the side wall of the sliding sleeve structure of the operating handle is provided with a handle positioning protrusion in the form of a raised part, and the handle positioning protrusion can be selectively inserted into the first handle positioning groove or the second handle positioning groove.

[0013] As a further improvement of the present invention, a fulcrum elastic arm with a cantilever structure is formed on the side wall of the sliding sleeve structure, and the handle positioning protrusion is provided on the free end side wall of the fulcrum elastic arm. The two side walls of the handle positioning protrusion along the sliding direction of the operating handle are in contact with the two side walls of the first handle positioning groove and the second handle positioning groove along the sliding direction of the operating handle through inclined surfaces.

[0014] As a further improvement of the present invention, the plug is provided with a handle slide extending along the sliding direction of the operating handle. The other end of the operating handle along its sliding direction is inserted into the handle slide. There is a set gap between the inner sidewall of the handle slide and the outer sidewall of the operating handle in the swing direction of the cantilever structure of the elastic hook. A radial limiting protrusion is provided on the inner sidewall of the handle slide. A radially concave clearance groove is provided on the outer sidewall of the other end of the operating handle, which can accommodate the radial limiting protrusion. When the handle positioning protrusion on the operating handle is located in the first handle positioning groove, the radial limiting protrusion is in close contact with the outer sidewall of the operating handle to prevent the operating handle from swinging. When the handle positioning protrusion on the operating handle is located in the second handle positioning groove, the radial limiting protrusion and the clearance groove on the outer sidewall of the operating handle are aligned, allowing the operating handle to swing at a set angle.

[0015] As a further improvement of the present invention, the handle slide is an inverted L-shaped channel with one end radial dimension smaller than the other end radial dimension. The operating handle is formed with an inverted L-shaped structure that matches the shape of the handle slide, with one end radial dimension smaller than the other end radial dimension. The stepped surfaces at both ends of the operating handle stop on the stepped surfaces at both ends of the handle slide. One end of the handle slide forms an inclined surface with the same swing angle as the operating handle along the swing direction of the operating handle, near the handle positioning protrusion on the side wall. The inner diameter of one end of the handle slide matches the outer diameter of one end of the operating handle. The inner diameter of the other end of the handle slide is larger than the outer diameter of the other end of the operating handle by a set size. The radial limiting protrusion is located inside the other end of the handle slide, and the clearance groove is located on the side wall of the other end of the operating handle.

[0016] As a further improvement of the present invention, the cantilever structure of the elastic hook is a bent structure with the free end inclined toward the annular slot. The side wall of the free end of the elastic hook cantilever structure facing away from the annular slot is provided with a reinforcing rib structure. The handle limiting block is also provided with an anti-detachment boss. There is a set gap between the end of the free end of the elastic hook and the reinforcing rib structure on the side wall of the free end of the elastic hook and the anti-detachment boss. The distance from the anti-detachment boss to the bend of the elastic hook cantilever mechanism is less than the length of the inclined bent structure of the free end of the elastic hook.

[0017] As a further improvement of the present invention, the side wall of the operating handle is provided with textures that rub against the fingers and unlocking and unlocking marks. The side wall of the other end of the operating handle along its sliding direction is also provided with an arc-shaped step surface for pushing it to swing. The arc-shaped step surface matches the curvature of the fingertip.

[0018] The beneficial effects of this invention are as follows: An operating handle is installed on the elastic hook of the plug. The operating handle drives the elastic hook to swing and disengage from the socket's mounting bracket, thus engaging and positioning the operating handle with the plug. Only after the operating handle is disengaged from the plug can the operating handle be rotated to rotate the elastic hook and disengage the plug from the socket. Disengagement of the elastic hook from the socket's mounting bracket is impossible when the operating handle is not disengaged from the plug. Furthermore, the disengagement direction of the operating handle from the plug is perpendicular to the direction of the elastic hook's swing during pressing, making the connection between the plug and socket more secure and stable after insertion and locking. This prevents the elastic hook and operating handle from disengaging from the mounting bracket due to external force when the plug and socket are locked, improving the stability of the connection after insertion and locking and ensuring the stability of electrical signal transmission. This invention also incorporates an anti-disengagement structure to prevent deformation of the elastic hook and detachment from the socket's mounting bracket when the plug is forcibly pulled, ensuring that the plug and socket cannot be separated under any circumstances unless the designed operation is followed, effectively enhancing the locking force between the plug and socket.

[0036] Example: A high-voltage energy storage quick-connect connector includes a socket 1 and a plug 2. The socket 1 has a ring-shaped or groove-shaped mounting platform 11 on its outer circumference. The plug 2 has an annular slot 21 on its inner side. The socket 1 and its mounting platform 11 can be inserted into the annular slot 21 of the plug 2. The annular slot 21 of the plug 2 has a cantilevered elastic hook 22 on its side wall. The cantilevered structure of the elastic hook 22 extends along the axial direction of the plug 2 in the free state. The hook body at the free end of the elastic hook 22 can hook onto the stepped surface of the mounting platform 11 facing away from the plug 2. An operating handle 3 is provided on the elastic hook 22 along its elastic deformation direction to stop it. The operating handle 3 can be connected to the plug 2 in the elastic deformation direction of the elastic hook 22.

[0037] After plug 2 and socket 1 are connected, the elastic hook 22 automatically hooks onto the mounting plate 11, locking plug 2 and socket 1. Then, the operating handle 3 is connected to plug 2 in a stop-locking manner. When the plug 2 and socket 1 connection structure is subjected to vibration or pulling, the elastic hook 22 cannot be disengaged from the mounting plate 11 because the handle and plug 2 remain in a stop-locking state. This ensures that plug 2 and socket 1 remain in a stable locked state, preventing the elastic hook 22 from swinging and unlocking plug 2 and socket 1 due to external forces caused by misoperation. This structure improves the stability of the connection between plug 2 and socket 1, facilitates stable transmission of electrical signals between them, and effectively avoids misoperation.

[0038] The operating handle 3 is mounted on the cantilever structure of the elastic hook 22, which can slide a set distance along the extension direction of the cantilever structure. A radially protruding handle limiting block 23 is provided on the outer circumference of the plug 2. The handle limiting block 23 has a limiting slot 231 extending axially along the plug 2. One end of the operating handle 3 along its sliding direction can be inserted into the limiting slot 231. The direction in which the operating handle 3 disengages from the limiting slot 231 is perpendicular to the swinging release direction of the elastic hook 22, preventing the operating handle 3 from disengaging from the plug 2 when the elastic hook 22 is pressed and swung, further improving the stability of the locking between the plug 2 and the socket 1.

[0039] The operating handle 3 has a first protrusion 31 on one side wall along its sliding direction, and a second protrusion 232 on the side wall of the limiting slot 231. The second protrusion 232 can generate interference force with the first protrusion 31 in the relative sliding direction. By inserting one end of the operating handle 3 into the limiting slot 231 of the handle limiting block 23, the first protrusion 31 on one side wall of the operating handle 3 and the second protrusion 232 on the inner side wall of the limiting slot 231 form a blocking structure, thereby making the two fastened together. Both sides of the first protrusion 31 along its sliding direction contact the second protrusion 232 through inclined surfaces, ensuring that the sliding operating handle 3 can disengage from the plug 2 and preventing the operating handle 3 from failing to disengage.

[0040] A sliding sleeve structure 32 is formed on the operating handle 3. The sliding sleeve structure 32 can be slidably fitted on the outside of the elastic buckle cantilever structure. A limiting protrusion 221 is also provided on the side wall of the cantilever structure of the elastic hook 22. A long strip-shaped limiting groove 33 is provided on the side wall of the operating handle 3 along its sliding direction relative to the elastic hook 22. The limiting protrusion 221 can be slidably inserted into the long strip-shaped limiting groove 33, and the limiting protrusion 221 stops on the two side walls of the long strip-shaped limiting groove 33 along its length direction.

[0041] The sidewall of the elastic hook 22 is preferably connected to the outer wall of the plug 2 by at least one connecting rib, so that a gap is formed between the sidewall of the elastic hook 22 and the outer wall of the plug 2 to accommodate the sliding sleeve structure 32. The sidewall of the sliding sleeve structure 32 can be opened to avoid the connecting rib of the elastic hook 22, or the root of the elastic hook 22 can extend a distance in the opposite direction from the position of the connecting rib to form a handle connecting section 224, and the sliding sleeve structure 32 is sleeved on the outside of the handle connecting section. Both of these structures can achieve the connection between the root of the elastic hook 22 and the outer wall of the plug 2 without affecting the sleeved structure 32 on the operating handle 3 and the relative sliding. In addition, a T-shaped opening slot can be formed on the operating handle 3, and a T-shaped protrusion can be provided on the sidewall of the cantilever structure of the elastic hook 22. The operating handle 3 and the elastic hook 22 can be connected together by sliding the T-shaped protrusion in the T-shaped opening slot, so that they can slide relative to each other along the extension direction of the cantilever structure of the elastic hook 22. These are equivalent replacement structures that can be easily conceived by those skilled in the art based on this application, and they all fall within the protection scope of this application.

[0042] The outer wall of the plug 2 is provided with a first handle positioning groove 24 and a second handle positioning groove 25 arranged at intervals along the sliding direction of the operating handle 3. The side wall of the sliding sleeve structure 32 of the operating handle 3 is provided with a raised handle positioning protrusion 34. The handle positioning protrusion 34 can be selectively inserted into either the first handle positioning groove 24 or the second handle positioning groove 25. The insertion of the handle positioning protrusion 34 into the first handle positioning groove 24 or the second handle positioning groove 25 realizes the positioning of the operating handle 3 at two positions along its sliding direction.

[0043] A cantilevered fulcrum elastic arm 35 is formed on the side wall of the sliding sleeve structure 32. The handle positioning protrusion 34 is located on the free end side wall of the fulcrum elastic arm 35. The two side walls of the handle positioning protrusion 34 along the sliding direction of the operating handle 3 are in contact with the two side walls of the first handle positioning groove 24 and the second handle positioning groove 25 along the sliding direction of the operating handle 3 through inclined surfaces. This ensures that the operating handle 3 slides smoothly and can automatically position itself when sliding to the locked and unlocked positions, preventing situations where the handle 3 is not locked properly or returns to the locked state after unlocking.

[0044] The plug 2 is provided with a handle slide 26 extending along the sliding direction of the operating handle 3. The other end of the operating handle 3 along its sliding direction is inserted into the handle slide 26. There is a set gap between the inner sidewall of the handle slide 26 and the outer sidewall of the operating handle 3 in the swing direction of the cantilever structure of the elastic hook 22. A radial limiting protrusion 261 is provided on the inner sidewall of the handle slide 26. A radially concave clearance groove 36 is provided on the outer sidewall of the other end of the operating handle 3, which can accommodate the radial limiting protrusion 261. When the handle positioning protrusion 34 on the operating handle 3 is located in the first handle positioning groove 24, the radial limiting protrusion 261 is in close contact with the outer sidewall of the operating handle 3 to prevent the operating handle 3 from swinging. When the handle positioning protrusion 34 on the operating handle 3 is located in the second handle positioning groove 25, the radial limiting protrusion 261 and the clearance groove 36 on the outer sidewall of the operating handle 3 are directly opposite each other, allowing the operating handle 3 to swing at a set angle.

[0045] When the operating handle 3 is slid into the state of being engaged with the plug 2, the radial limiting protrusion 261 on the side wall of the handle slide 26 presses against the other side wall of the operating handle 3, so that the operating handle 3 cannot swing within the handle slide 26, thereby preventing the elastic buckle from swinging on its own due to vibration when it is locked. When the operating handle 3 is slid to the clearance groove 36 on it and the radial limiting protrusion 261 on the side wall of the handle slide 26 are aligned, the operating handle 3 can swing at a certain angle to open the elastic hook 22.

[0046] The handle slide 26 is an inverted L-shaped channel with one end radial dimension smaller than the other end radial dimension. The operating handle 3 forms an inverted L-shaped structure with one end radial dimension smaller than the other end radial dimension, matching the shape of the handle slide 26. The stepped surfaces at both ends of the operating handle 3 stop on the stepped surfaces at both ends of the handle slide 26. One end of the handle slide 26 forms an inclined surface 262 on the side wall of the operating handle 3 close to the handle positioning protrusion 34 along the swing direction of the operating handle 3, which is consistent with the swing angle of the operating handle 3. The inner diameter of one end of the handle slide 26 matches the outer diameter of one end of the operating handle 3. The inner diameter of the other end of the handle slide 26 is larger than the outer diameter of the other end of the operating handle 3 by a set size. The radial limiting protrusion 261 is located on the inner side of the other end of the handle slide 26. The clearance groove 36 is located on the side wall of the other end of the operating handle 3. When the operating handle 3 swings, it uses the side wall of the operating handle 3 and one end of the handle slide 26 as the fulcrum. After the operating handle 3 swings to a certain angle, it is blocked by the inclined surface 262 and cannot continue to swing. This achieves the limitation of the swing angle of the operating handle 3. Such structures can be arbitrarily selected by those skilled in the art according to actual needs and are all within the protection scope of this application.

[0047] The cantilever structure of the elastic hook 22 is a bent structure 222 with its free end inclined towards the annular slot 21. A reinforcing rib structure 223 is provided on the side wall of the free end of the cantilever structure facing away from the annular slot 21. An anti-detachment protrusion 233 is also provided on the handle limiting block 23. A set gap exists between the free end of the elastic hook 22 and the reinforcing rib structure 223 on the side wall of the free end of the elastic hook 22, and between the anti-detachment protrusion 233 and the cantilever mechanism of the elastic hook 22. The distance from the anti-detachment protrusion 233 to the bend of the cantilever mechanism of the elastic hook 22 is less than the length of the inclined bent structure 222 at the free end of the elastic hook 22. This structure increases the strength of the inclined bent structure 222 of the elastic hook 22 and prevents breakage at the connection between the hook body and the cantilever structure of the elastic hook 22 when the plug 2 is pulled out, thus avoiding hook detachment.

[0048] The operating handle 3 has textured surfaces 37 that rub against the fingers and unlock / unlock markings 38 on its sidewall. The other end of the operating handle 3 along its sliding direction also has an arc-shaped stepped surface 39 for propelling its swing. This arc-shaped stepped surface 39 matches the curvature of a human fingertip, facilitating sliding and pressing of the operating handle 3.
