Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a secondary locking structure for a high-voltage energy storage connector. Background Technology

[0002] Connectors, also known as plugs, sockets, and connectors, are devices that connect two active devices to transmit current or signals. They are components frequently encountered by electronic engineers, used to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Because connectors need to be used continuously for extended periods after connection, and may even need to be moved as a whole, their stability after connection is increasingly important. Most mainstream connectors currently use a single-locking mechanism, which increases the probability of accidental contact. Accidental contact can easily cause the plug and socket to fall apart, posing a safety hazard. Some connectors use a double-locking mechanism, but this requires two actions to achieve the double-locking effect, and improper operation cannot prevent only single-locking from being achieved.

[0003] For example, CN117791234A discloses a plug structure and a socket structure electrically connected thereto. The plug structure includes a housing, and the socket structure includes a rubber shell movably installed inside the housing. The housing contains an integrally molded terminal, and the integrally molded terminal contains a crown spring. The rubber shell contains an inner conductor, which is installed inside the crown spring and electrically connected to the integrally molded terminal via the crown spring. A button mechanism is movably connected inside the housing. The button mechanism includes a button body, and a locking button that can move up and down is movably connected to the button body. The button body has a first arc-shaped slot and a second arc-shaped slot on its front and rear sides, respectively. The locking button contains... The wall has an arc-shaped damping protrusion that mates with the first and second arc-shaped slots. A sliding groove is provided on the right side of the button body. A sliding rod is movably connected to the inner wall of the locking button within the sliding groove. A fixing head for limiting the position of the rubber shell is provided at the top of the button body. An elastic claw is provided on the front side of the button body. A spring is installed on the inner wall of the button body. A nut sleeve is threaded onto the bottom of the shell. A wire harness conductor is located inside the nut sleeve. A waterproof sleeve is fitted onto the surface of the wire harness conductor for sealing. Three corrugated grooves are provided inside the waterproof sleeve. A support sleeve for limiting the position of the waterproof sleeve is provided on the inner wall of the nut sleeve. A crimping ring is provided between the surface of the wire harness conductor and the inner wall of the integrally formed terminal to increase the connection's firmness. After the plug structure is inserted into the socket structure, a primary locking is achieved through the button body, followed by a secondary locking through the locking button. However, due to improper operation by some personnel, the locking button may fail to lock the plug and socket structures, leaving only the button body as the effective locking mechanism, which can easily lead to accidental activation. Although a secondary locking function can be achieved, it cannot prevent the possibility of only a single locking due to improper operation. Summary of the Invention

[0004] The purpose of this invention is to provide a secondary locking structure for a high-voltage energy storage connector, which aims to solve the technical problem that the existing technology requires two actions to achieve the effect of locking twice, and cannot avoid the problem that only one locking can be achieved due to improper operation by personnel.

[0005] To achieve the above objectives, embodiments of the present invention provide a secondary locking structure for a high-voltage energy storage connector, comprising a first connector and a second connector. The first connector includes a socket and several steps surrounding the end of the socket. The second connector includes a body, a slot, and a plug. A button groove is connected to the bottom of the slot and extends through the left and right sides of the body. A column is slidably connected within the button groove. A first button is provided on one side of the column. A sliding groove is provided through the middle of the column. A spring groove is provided at one end of the sliding groove near the first button, and the other end opens outward. A spring is provided in the spring groove. A first locking block is provided at the top of the column. A sliding rod is slidably connected within the sliding groove. One end of the sliding rod abuts against the spring, and the other end is provided with a second button. A second locking block is provided at the end of the sliding rod. Both the first and second locking blocks have chamfered front sides. The first button and the second button are respectively limited and engaged with the left and right sides of the button groove. The rear sides of the first and second locking blocks engage with the steps.

[0006] Preferably, the front side of the column is provided with a first guide portion for guiding the column to slide within the key slot. A limiting spring is provided in the middle of the guide portion. One end of the limiting spring is fixedly connected to the guide portion, and the other end extends obliquely towards the first key.

[0007] Preferably, the button slot is recessed with a guide groove, and the bottom of the slide bar extends downward with a second guide portion, which is slidably connected to the guide groove.

[0008] Preferably, the main body is provided with pressing grooves on both sides, and the two ends of the button groove are connected to the pressing grooves, wherein one of the pressing grooves is in contact with the first button.

[0009] Preferably, one of the pressing grooves is surrounded by a plurality of elastic buckles, each of the elastic buckles cooperating with the second button for limiting.

[0010] Preferably, a positioning post is coaxially provided at the end of the slide rod, one end of the spring is installed in the spring groove, and the other end is sleeved on the surface of the positioning post.

[0011] Preferably, the step is slidably connected to the slot, and the inner wall of the slot is provided with a plurality of positioning bosses, which are slidably positioned with respect to the gap between the positioning bosses and each step.

[0012] Preferably, the outer surface of the plug is provided with a waterproof rubber ring, which slides in conjunction with the socket.

[0013] The secondary locking structure of the high-voltage energy storage connector provided in this embodiment of the invention has at least one of the following technical effects:

[0014] In use, the second connector is inserted into the first connector; during this process, the plug is inserted into the socket, and simultaneously, the outer edge of the socket extends into the slot. As the outer edge of the socket continues to extend, the step on the outer edge of the socket presses against the first locking block on one side, pushing the column to slide into the button slot. This causes the step on the outer edge of the socket to pass the middle of the two first locking blocks, then contact and press against the second locking block, thereby driving the slide rod to slide towards the side closer to the first button in the slide groove, and elastically compressing the spring, causing the step on the outer edge of the socket to pass over the second locking block. As the second locking block loses the pressure of the step, the spring elastically extends, pushing the slide rod in... The slide bar moves away from the first button within the groove, simultaneously resetting the second locking block. This engages the outer edge of the socket with the first and second locking blocks, achieving a locking effect. To unlock, the user presses the first and second buttons on either side of the main body, causing the column to slide into the button groove and releasing the first locking block from the step. Simultaneously, the slide bar slides into the groove, engaging the second locking block with the step, allowing the second connector to be pulled out and separated from the first connector. Unlocking requires pressing both the first and second buttons simultaneously to ensure the safety of the connection between the first and second connectors. Attached Figure Description

Therefore, they should not be construed as limitations on the present invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0032] In one embodiment of the present invention, such as Figures 1-11 As shown, a secondary locking structure for a high-voltage energy storage connector is provided, including a first connector 1 and a second connector 2. The first connector 1 includes a socket 11 and several steps 12 surrounding the end of the socket 11. The second connector 2 includes a body 20, a slot 21, and a plug 22. A button groove 211 is connected to the bottom of the slot 21, and the button groove 211 extends through the left and right sides of the body 20. A column 3 is slidably connected in the button groove 211. A first button 4 is provided on one side of the column 3. A sliding groove is provided through the middle of the column 3, and a groove is provided at the end of the sliding groove near the first button 4. A spring groove 311 has one end open to the outside. A spring 312 is provided in the spring groove 311. A first locking block 321 is provided at the top of the column 3. A sliding rod 33 is slidably connected in the sliding groove. One end of the sliding rod 33 abuts against the spring 312, and the other end is provided with a second button 5. A second locking block 331 is provided at the end of the sliding rod 33. The front sides of the first locking block 321 and the second locking block 331 are both provided with chamfers 6. The first button 4 and the second button 5 are respectively limited and cooperated with the left and right sides of the button groove 211. The rear sides of the first locking block 321 and the second locking block 331 are engaged with the step 12.

[0033] Furthermore, a first guide portion 34 is provided on the front side of the column 3 to enable the column 3 to slide within the button slot 211. A limiting spring piece 341 is provided in the middle of the guide portion. One end of the limiting spring piece 341 is fixedly connected to the guide portion, and the other end extends obliquely towards the first button 4. Specifically, by setting the guide part 34, the linear effect of the column 3 sliding in the button slot 211 can be improved. When only the first button 4 is pressed, the column 3 slides into the button slot 211. At the same time, the column 3 pushes the slide bar 33 outward through the spring 312 until the side of the first button 4 abuts against the main body of the second connector 2. When only the first button 4 is pressed, the column 3 can only be pushed to slide in the pressing groove 201, and the unlocking effect cannot be achieved. When only the second button 5 is pressed, the slide bar 33 pushes the column 3 to slide in the button slot 211 through the spring 312 until the limiting spring 341 is engaged with the button slot 211. The second button 5 cannot push the second locking block 331 to move closer to the first button 4 to achieve the unlocking effect while compressing the spring 312. This avoids unlocking by pressing either the first button 4 or the second button 5, and achieves the effect of preventing accidental touch.

[0034] Furthermore, a guide groove 213 is recessed downward within the button slot 211, and a second guide portion 333 extends downward from the bottom of the slide rod 33, the second guide portion 333 being slidably connected to the guide groove 213. Specifically, when the first button 4 and the second button 5 are pressed simultaneously to achieve the unlocking effect, the second button 5 pushes the slide rod 33, and the second guide portion 333 at the bottom of the slide rod 33 slides within the guide groove 213, achieving a better linear sliding effect.

[0035] Furthermore, the main body 20 is provided with pressing grooves 201 on both sides, and the two ends of the button groove 211 are connected to the pressing grooves 201. One of the pressing grooves 201 is in limiting contact with the first button 4. A plurality of elastic buckles 202 are arranged around the outer side of one of the pressing grooves 201, and each elastic buckle 202 is in limiting contact with the second button 5. Specifically, when the first button 4 is not pressed and only the second button 5 is pressed, the second button 5 pushes the slide bar 33, which drives the spring 312 to push the column 3 to slide out of the button groove 211. Finally, the second button 5 is in limiting contact with the elastic buckles 202 in the pressing groove 201 on the same side and cannot be pushed further. When the second button 5 is not pressed and only the first button 4 is pressed, the first button 4 pushes the column 3, which drives the spring 312 to push the slide bar 33 to slide out of the button groove 211. Finally, the first button 4 is in limiting contact with the pressing groove 201 on the same side and cannot be pushed further.

[0036] Furthermore, a positioning post 332 is coaxially provided at the end of the slide rod 33. One end of the spring 312 is installed in the spring groove 311, and the other end is sleeved on the surface of the positioning post 332. Specifically, one end of the spring 312 is sleeved on the surface of the positioning post 332, and the other end is installed in the spring groove 311. At the same time, the positioning post 332 can also be provided in the spring groove 311. The spring 312 is installed in the spring groove 311 and also sleeved on the surface of the positioning post 332 in the spring groove 311, so as to achieve a good effect of fixing the spring 312.

[0037] Furthermore, the step 12 is slidably connected to the slot 21. The inner wall of the slot 21 is provided with several positioning protrusions 212, and the positioning protrusions 212 are slidably positioned with the gaps 121 between each step 12. Specifically, the gaps 121 between the steps 12 are aligned with the positioning protrusions 212 to restrict the rotation of the first connector 1 and the second connector 2. Then, the plug 22 is inserted into the socket 11, and the outer edge of the socket 11 simultaneously penetrates into the slot 21. As the outer edge of the socket 11 continues to penetrate, the step 12 of the outer edge of the socket 11 presses against the first locking block 321 on one side, pushing the column 3 to slide into the key slot 211, so that the step 12 of the outer edge of the socket 11 passes over the middle of the two first locking blocks 321, and then contacts and presses against the second locking block 331, so that the first... The second locking block 331 slides within the limiting groove, simultaneously driving the slide rod 33 to slide towards the side closer to the first button 4 within the slide groove, and elastically compressing the spring 312, causing the step 12 on the outer edge of the socket 11 to pass over the second locking block 331. As the second locking block 331 loses the compression of the step 12, the spring 312 elastically extends, pushing the slide rod 33 to slide away from the first button 4 within the slide groove, while simultaneously driving the second locking block 331 to reset, thus achieving the locking effect by engaging the step 12 on the outer edge of the socket 11 with the rear side of the first locking block 321 and the second locking block 331.

[0038] Furthermore, a waterproof rubber ring 221 is provided on the outer surface of the plug 22, and the waterproof rubber ring 221 slides in engagement with the socket 11. Specifically, the waterproof rubber ring 221 provides slight resistance when the plug 22 is inserted into or removed from the socket 11, further improving the connection strength between the first connector 1 and the second connector 2.

[0039] Working principle: In use, the second connector 2 is inserted into the first connector 1; during this process, the plug 22 is inserted into the socket 11, and simultaneously, the outer edge of the socket 11 extends into the slot 21. As the outer edge of the socket 11 continues to extend, the step 12 of the outer edge of the socket 11 presses against the first locking block 321 on one side, pushing the column 3 to slide into the button slot 211, so that the step 12 of the outer edge of the socket 11 passes over the middle of the two first locking blocks 321, and then contacts and presses against the second locking block 331, thereby driving the slide rod 33 to slide in the slide groove towards the side closer to the first button 4, and elastically compressing the spring 312, so that the step 12 of the outer edge of the socket 11 passes over the second locking block 331. Since the second locking block 331 loses the compression of the step 12, the spring 312 becomes elastic. Extending the slide bar 33 pushes it to slide away from the first button 4 within the slide groove, simultaneously driving the second locking block 331 to reset, thus locking the step 12 on the outer edge of the socket 11 with the rear of the first locking block 321 and the second locking block 331. To unlock, the user presses the first button 4 and the second button 5 on both sides of the main body 20, causing the column 3 to slide into the button groove 211 and releasing the first locking block 321 from the step 12. Simultaneously, the slide bar 33 slides into the slide groove, releasing the second locking block 331 from the step 12, allowing the second connector 2 to be pulled out and separated from the first connector 1. To ensure the safety of the connection between the first connector 1 and the second connector 2, the first button 4 and the second button 5 must be pressed simultaneously during unlocking.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
