Description

Technical Field

[0001] This utility model relates to the field of energy storage connector technology, specifically to a pin-type unlocking energy storage connector. Background Technology

[0002] Energy storage connectors are used for high-current connections between different battery modules or for power transmission connections between energy storage devices. The basic function of an energy storage connector is to achieve a stable connection between energy devices and energy storage systems, responsible for transferring energy from power generation equipment to energy storage devices, and releasing energy from the storage devices when needed to supply the load. Through energy storage connectors, efficient energy utilization and supply-demand balance can be achieved.

[0003] Existing energy storage connectors include plugs and sockets, which are connected by a locking structure, typically a side-press spring-loaded latch, enabling a detachable connection between the plug and socket. However, side-press unlocking requires more lateral unlocking space. When multiple connectors are installed close together, it is difficult to insert fingers for unlocking, which is not conducive to densely packed installations. In addition, the press-type spring-loaded latch is directly pressed to unlock without any anti-accidental touch function, which may cause the plug and socket to separate due to accidental contact.

[0004] The above-mentioned defects urgently need to be addressed. Utility Model Content

[0005] To address the issues of existing energy storage connectors being unsuitable for densely packed installations and lacking anti-accidental contact functionality, this invention provides a pin-type unlocking energy storage connector.

[0006] The technical solution of this utility model is as follows:

[0007] A plug-type unlocking energy storage connector includes a plug, a socket, a latch, and a key. The plug is inserted into the socket. The plug has a mounting groove. The latch is movably disposed in the mounting groove by an elastic element. The plug has a insertion hole that cooperates with the latch. The key can be movably inserted into the insertion hole so that the latch can switch between a locked state and an unlocked state.

[0008] When the latch is in the locked state, the latch engages with the socket;

[0009] When the latch is in the unlocked state, the key is inserted into the socket, and the latch moves away from the key to separate the plug from the socket.

[0010] According to the above-described solution of this utility model, the top of the socket is provided with a socket buckle, and the buckle is provided with a buckle rib. When the buckle is in the locked state, the socket buckle engages with the buckle rib.

[0011] According to the present utility model with the above-described solution, the latch is provided with an inner hole, the inner hole is provided with a mounting post, at least a portion of the elastic member is sleeved on the mounting post, and the end of the elastic member away from the latch abuts against the side wall of the mounting groove.

[0012] According to the present utility model with the above-described solution, a plug buckle is provided on the side wall of the mounting groove, and a locking hook is provided on the latch. The plug buckle engages with the locking hook to prevent the latch from dislodging from the plug.

[0013] According to the present utility model with the above-described solution, the end of the latch is provided with a first inclined surface, and the key is provided with a corresponding second inclined surface. The first inclined surface and the second inclined surface cooperate to slide the latch along the mounting groove.

[0014] According to the present utility model with the above solution, the mounting groove is arranged horizontally along the plug, the plug hole is arranged vertically along the plug, the mounting groove communicates with the plug hole, and the side wall of the plug hole is provided with an opening to facilitate the installation of the latch.

[0015] According to the above-described solution of this utility model, a protrusion is provided in the insertion hole, and a recess is provided at the end of the key. When the latch is in the unlocked state, the protrusion and the recess are engaged.

[0016] According to the above-described solution of this utility model, both sides of the key are provided with protrusions, and when the latch is in the unlocked state, the protrusions abut against the top of the insertion hole.

[0017] According to the above-described scheme of this utility model, the top of the key is provided with an anti-slip structure.

[0018] According to the above-described scheme of this utility model, the top of the key is provided with a hanging hole.

[0019] The advantages of this utility model based on the above solution are as follows:

[0020] In the aforementioned pin-type unlocking energy storage connector, when the latch is in the unlocked state, the key is inserted into the socket, and the latch moves away from the key to separate the plug and socket. This means that the plug and socket of this invention are unlocked via a key, eliminating the need for additional lateral unlocking space. This saves lateral space, resulting in a smaller required unlocking space, allowing multiple connectors to be compactly arranged in a limited space. This is particularly beneficial for energy storage connectors installed in densely packed installation scenarios, making unlocking more convenient. Furthermore, the key in this invention is a dedicated unlocking tool that prevents accidental contact, effectively preventing accidental separation of the plug and socket, thus ensuring the stability and security of energy transmission.

[0043] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0044] like Figures 1 to 6 , Figure 10As shown, this utility model provides a pin-type unlocking energy storage connector, including a plug 1, a socket 2, a latch 3, and a key 4. The plug 1 is inserted into the socket 2. The plug 1 has a mounting groove 11. The latch 3 is movably disposed in the mounting groove 11 via an elastic element 5. The plug 1 has a insertion hole 12 that cooperates with the latch 3. The key 4 can be movably inserted into the insertion hole 12, allowing the latch 3 to switch between a locked state and an unlocked state. When the latch 3 is in the locked state, the latch 3 engages with the socket 2, thereby installing the plug 1 and the socket 2 together. When the latch 3 is in the unlocked state, the key 4 is inserted into the insertion hole 12, and the latch 3 moves away from the key 4 to separate the plug 1 and the socket 2. That is, the plug 1 and socket 2 of this utility model achieve pin-type unlocking through the key 4, eliminating the need for additional lateral unlocking space, saving lateral space, and requiring less unlocking space. This allows multiple connectors to be compactly arranged in a limited space, which is more conducive to the installation of energy storage connectors in densely packed installation scenarios, and makes unlocking more convenient. Furthermore, the key 4 of this invention is a dedicated unlocking tool that prevents accidental contact, effectively preventing the plug 1 from accidentally separating from the socket 2, thus ensuring the stability and safety of energy transmission. In addition, compared to the existing push-button latch 3, the pin-type latch 3 of this invention has only three parts, saving the cost of one part and improving production efficiency.

[0045] like Figure 3 , Figure 4 , Figure 16 As shown, in this embodiment, the latch 3 has an inner latch hole 31, and a mounting post 32 is provided within the inner latch hole 31. At least a portion of the elastic element 5 is sleeved on the mounting post 32, and the end of the elastic element 5 away from the latch 3 abuts against the side wall of the mounting groove 11 of the plug 1. This allows the elastic element 5 to provide force during the unlocking process, helping the latch 3 smoothly transition from the locked state to the unlocked state. Similarly, during the locking process, the preload of the elastic element 5 ensures a tight engagement between the latch 3 and the socket 2, preventing accidental separation due to vibration or external interference. Furthermore, the elastic element 5 can be designed as a spring. A spring with elasticity, when installed in the plug 1 in conjunction with the latch 3, can realize the pressing and rebound of the latch 3. Of course, in actual design, the structure of the elastic element 5 can be designed according to actual needs.

[0046] like Figure 3 , Figure 4 As shown, in this embodiment, a plug buckle 13 is provided on the side wall of the mounting groove 11 of the plug 1, and a locking hook 33 is provided on the latch 3. The plug buckle 13 and the locking hook 33 are engaged, thereby limiting the stroke of the latch 3 and preventing the latch 3 and the elastic member 5 from coming out of the mounting groove 11 of the plug 1, thus ensuring the stability and reliability of the connection.

[0047] like Figure 9, Figure 15 As shown, in this embodiment, the mounting groove 11 is arranged horizontally along the plug 1, and the insertion hole 12 is arranged vertically along the plug 1. The mounting groove 11 communicates with the insertion hole 12, maximizing the use of space inside the plug 1. When the key 4 is inserted into the insertion hole 12, the vertical movement of the key 4 can be converted into the horizontal movement of the latch 3, simplifying the operation of the latch 3 and improving its reliability and stability. In addition, an opening 14 is provided on the side wall of the insertion hole 12 to facilitate the installation of the latch 3 and ensure that the latch 3 can be firmly installed on the plug 1. Furthermore, a foolproof notch 15 is provided on one side of the opening 14 to ensure that the latch 3 and the spring are installed into the mounting groove 11 of the plug 1 in a unique manner, improving installation efficiency.

[0048] like Figures 7 to 14 As shown, in this embodiment, the top of the socket 2 is provided with a socket buckle 21, and the lower side of the socket buckle 21 is provided with a snap-fit ​​groove 22. The latch 3 is provided with a latch rib 34. When the latch 3 is in the locked state, at least a portion of the latch rib 34 is disposed in the snap-fit ​​groove 22, and the socket buckle 21 is engaged with the latch rib 34, thereby completing the insertion of the plug 1 and the socket 2. This can prevent circuit interruption or signal loss caused by the plug 1 accidentally falling off, thereby improving the safety of the system. When the latch 3 is in the unlocked state, the latch rib 34 does not contact the socket buckle 21, thereby facilitating the separation of the plug 1 and the socket 2. The plug 1 can be easily pulled out without additional tools or complicated operating steps, improving the convenience of use.

[0049] like Figure 12 , Figure 13 As shown, in this embodiment, the end of the latch 3 is provided with a first inclined surface 35, and the key 4 is correspondingly provided with a second inclined surface 41. The first inclined surface 35 and the second inclined surface 41 cooperate to slide the latch 3 along the mounting groove 11, making the separation process between the plug 1 and the socket 2 smoother. When the key 4 is inserted into the insertion hole 12 of the plug 1, the second inclined surface 41 of the key 4 slides along the first inclined surface 35 of the latch 3, causing the latch 3 to move away from the key 4, thereby preventing the latch rib 34 of the latch 3 from contacting the socket buckle 21, thus unlocking the plug 1 and the socket 2. In addition, the cross-sectional shape of the insertion hole 12 is trapezoidal, that is, the length of one side wall of the insertion hole 12 is greater than the length of the other side wall, which can play a foolproof role, ensuring that the key 4 is inserted into the insertion hole 12 in a unique way, improving assembly efficiency.

[0050] like Figures 12 to 13As shown, in this embodiment, a protrusion 16 is provided in the insertion hole 12, and a recess 42 is provided at the end of the key 4. When the latch 3 is in the unlocked state, the protrusion 16 and the recess 42 are engaged, thereby limiting the key 4 and keeping the latch 3 in the unlocked state, ensuring that the plug 1 and the socket 2 are unlocked. At the same time, the protrusion 16 in the insertion hole 12 helps to fix the position of the key 4, preventing the key 4 from shaking or accidentally falling out in the insertion hole 12, improving the stability of the unlocked state, and ensuring that the plug 1 and the socket 2 can remain in the unlocked state.

[0051] like Figures 11 to 13 As shown, in this embodiment, protrusions 43 are provided on both sides of the key 4. When the latch 3 is in the unlocked state, the protrusions 43 abut against the top of the insertion hole 12, thereby further limiting the key 4 and effectively restricting the range of movement of the key 4 within the insertion hole 12, thus enhancing the stability of the key 4. Even under external force or vibration, the key 4 can maintain a relatively stable position and is not easily dislodged or shaken.

[0052] like Figure 17 As shown, in this embodiment, the top of the key 4 is provided with an anti-slip structure 44, which is an anti-slip raised strip. This structure is ergonomically designed to increase the surface roughness of the key 4, providing better friction for the fingers when gripping it, thus improving grip stability and ease of handling. Furthermore, the top of the key 4 is provided with a hanging hole 45, allowing the user to hang the key 4 on a keychain, key ring, or other carrying tool for convenient portability and to prevent loss or forgetting, thereby improving user convenience.

[0053] During assembly, the elastic element 5 is installed on the mounting post 32 of the inner hole 31 of the latch, and then the latch 3 and the elastic element 5 are installed together in the mounting groove 11 through the opening 14 of the plug 1, so that the plug buckle 13 of the plug 1 is engaged with the locking hook 33 of the latch 3 to prevent the latch 3 and the elastic element 5 from coming out of the mounting groove 11 of the plug 1.

[0054] When plug 1 is inserted into socket 2, the socket buckle 21 of socket 2 pushes open the locking rib 34 of locking buckle 3, causing the locking rib 34 of locking buckle 3 to be axially pushed into the mounting groove 11 of plug 1, compressing the elastic element 5 until the socket buckle 21 and locking rib 34 are engaged, that is, when the plug is installed in place, the locking buckle 3 rebounds under the elastic force of the elastic element 5, and the locking rib 34 interferes with the socket buckle 21, and plug 1 and socket 2 are fully inserted. At this time, the locking buckle 3 is in the locked state.

[0055] To unlock, insert key 4 into the socket 12 of plug 1. The operator presses key 4 downwards, causing it to move vertically downwards until the recess 42 of key 4 engages with the protrusion 16 of plug 1. Simultaneously, the protrusion 43 of key 4 clicks against the top of plug 1, indicating unlocking is complete. During key 4 insertion, latch 3 gradually moves axially into the mounting groove 11 of plug 1. The interference between latch rib 34 and socket buckle 21 gradually decreases until key 4 is fully inserted, at which point the interference disappears, and socket buckle 21 and latch rib 34 no longer contact each other. Plug 1 and socket 2 are then separated. At this point, latch 3 is in the unlocked state. Plug 1 can be removed first, followed by key 4.

[0056] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0057] The present utility model patent has been described above with reference to the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
