Description

Technical Field

[0001] This utility model discloses a plug-in distribution box, which belongs to the field of distribution box technology. Background Technology

[0002] In practical applications, existing plug-in distribution boxes often suffer from structural design flaws in their lifting components, which are crucial for height adjustment. For example, many use a single cylinder drive or have cylinders arranged without asymmetrical planning, leading to unbalanced forces during lifting and lowering, making them prone to tilting and swaying. This, in turn, affects the precise alignment of plugs and sockets and the plugging and unplugging operation. At the same time, some lifting components lack dedicated insulation structure design, which may cause electric shock risks due to insufficient insulation in live plugging and unplugging scenarios. This makes it difficult to meet the needs of scenarios with high requirements for lifting stability and electrical safety, such as industrial sites and shipbuilding. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of uneven force on the distribution box during the lifting process due to unreasonable structural design of the lifting component of the existing plug-in distribution box, easy tilting and shaking that affects the precise matching of plug and socket, and electric shock safety hazards caused by lack of insulation protection.

Detailed Implementation

[0016] The following is based on the appendix Figure 1-3 Further explanation of this utility model: The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 and Figure 2 As shown, the first embodiment of this utility model provides a pluggable distribution box based on the prior art, including: a distribution box unit 10, the distribution box unit 10 having a socket; and a lifting assembly 20, the lifting assembly 20 including: an insulating chassis assembly, a first lifting cylinder 206 and a second lifting cylinder 209, the insulating chassis assembly being spaced apart from the distribution box unit 10, the first lifting cylinder 206 being located above the insulating chassis assembly, the fixing seat of the first lifting cylinder 206 being connected to the insulating chassis assembly, the actuating end of the first lifting cylinder 206 being connected to the bottom of the distribution box unit 10, the second lifting cylinder 209 being located above the insulating chassis assembly, the fixing seat of the second lifting cylinder 209 being connected to the insulating chassis assembly, the actuating end of the second lifting cylinder 209 being connected to the bottom of the distribution box unit 10, and the second lifting cylinder 209 and the first lifting cylinder 206 being symmetrically arranged about the geometric center of the distribution box unit 10.

[0020] In this embodiment, the insulating chassis assembly and the distribution box unit 10 are spaced apart, which can effectively achieve insulation protection and improve electrical safety. The first lifting cylinder 206 and the second lifting cylinder 209 are symmetrically arranged about the geometric center of the distribution box unit 10, which can make the force on the distribution box unit 10 uniform during the lifting process, ensuring its smooth lifting and lowering, thereby ensuring the accurate insertion and removal of the socket. At the same time, the dual-cylinder symmetrical drive structure also enhances the stability and reliability of the lifting assembly 20.

[0021] like Figure 3 As shown, the socket mates with the first contactor. The first terminal of the first contactor is electrically connected to the controller, and the second terminal of the first contactor is electrically connected to the indicator light. The controller is electrically connected to the second contactor, the first terminal of the second contactor is electrically connected to the first terminal of the circuit breaker, the second terminal of the second contactor is electrically connected to the first terminal of the shunt trip unit, and the second terminal of the circuit breaker is electrically connected to the second terminal of the shunt trip unit. When the socket and plug are in the mated position, the controller is connected to the indicator light through the first contactor. When the socket and plug are in the disengaged position, the controller is disconnected from the indicator light through the first contactor. When the first contactor is disconnected, the controller sends a connection signal to the second contactor, and the second contactor is in the connected state. The circuit breaker and shunt trip unit are in the connected state, so that the shunt trip unit drives the circuit breaker to perform the tripping state. The socket has a built-in mechanical trigger plate. When the plug is inserted into the socket (matted position), the trigger plate pushes the first contactor to close. When the plug is pulled out of the socket (disengaged position), the trigger plate resets, causing the first contactor to open.

[0022] In this embodiment, the socket cooperates with the first contactor, and the electrical connection between the first contactor, controller, indicator light, second contactor, circuit breaker, and shunt trip unit allows the controller to connect the indicator light via the first contactor when the socket and plug are in the mated position, providing a clear indication of the connection status. When the socket and plug are in the disengaged position, the first contactor disconnects, causing the controller to send a connection signal to the second contactor. After the second contactor connects, the circuit breaker and shunt trip unit are in the connected state, thereby causing the shunt trip unit to drive the circuit breaker to perform the tripping state. This effectively avoids electric arc injuries and damage to the plug and socket during live plugging and unplugging, significantly improving electrical safety and equipment reliability.

[0023] In this embodiment, the insulating chassis assembly includes: an insulating bracket 203, a fixing seat for the second lifting cylinder 209 and a fixing seat for the first lifting cylinder 206 respectively connected to the insulating bracket 203; a first elastic support 201, the first end of the first elastic support 201 connected to the insulating bracket 203, and the second end of the first elastic support 201 connected to the bottom of the distribution box unit 10; a second elastic support 204, the second elastic support 204 being spaced apart from the first elastic support 201, the first end of the second elastic support 204 being connected to the insulating bracket 203, and the second end of the second elastic support 204 being connected to the bottom of the distribution box unit 10; and a third elastic support 205, the third elastic support 205 being respectively connected to the first... Two elastic support bases 204 and the first elastic support base 201 are spaced apart. The first end of the third elastic support base 205 is connected to the insulating bracket 203, and the second end of the third elastic support base 205 is connected to the bottom of the distribution box unit 10. A fourth elastic support base 208 is spaced apart from the third elastic support base 205, the second elastic support base 204 and the first elastic support base 201. The first end of the fourth elastic support base 208 is connected to the insulating bracket 203, and the second end of the fourth elastic support base 208 is connected to the bottom of the distribution box unit 10. The first elastic support base 201, the second elastic support base 204, the third elastic support base 205 and the fourth elastic support base 208 are spaced apart.

[0024] In this embodiment, the insulating bracket 203 not only securely connects the fixing bases of the second lifting cylinder 209 and the first lifting cylinder 206, providing a reliable installation foundation, but also enhances the overall insulation protection due to its own insulation properties. The first elastic support base 201, the second elastic support base 204, the third elastic support base 205, and the fourth elastic support base 208 are arranged at intervals, with one end connected to the insulating bracket 203 and the other end connected to the bottom of the distribution box unit 10, forming a multi-point elastic support structure. This structure can not only work with the first lifting cylinder 206 and the second lifting cylinder 209 to improve the stability of the distribution box unit 10 during lifting, but also effectively buffer external vibrations through its elastic properties, preventing the internal components of the distribution box unit 10 from loosening or being damaged due to vibration. Furthermore, the spaced distribution makes the force more even, further enhancing the stability and impact resistance of the overall structure.

[0025] In one exemplary embodiment, the second elastic support 204 and the third elastic support 205 are respectively disposed adjacent to the first lifting cylinder 206, and the first elastic support 201 and the fourth elastic support 208 are respectively disposed adjacent to the second lifting cylinder 209.

[0026] In this embodiment, the second elastic support 204 and the third elastic support 205 are respectively arranged adjacent to the first lifting cylinder 206, and the first elastic support 201 and the fourth elastic support 208 are respectively arranged adjacent to the second lifting cylinder 209. This structure allows each lifting cylinder to form a close and coordinated support with the adjacent elastic support. When the first lifting cylinder 206 drives the distribution box unit 10 to lift, the adjacent second elastic support 204 and the third elastic support 205 can simultaneously provide elastic support and buffer the impact force of its movement. When the second lifting cylinder 209 moves, the adjacent first elastic support 201 and the fourth elastic support 208 can also play the same auxiliary support and buffering role. This effectively avoids local stress concentration caused by the lifting cylinder being subjected to force alone, making the force transmission of the distribution box unit 10 more uniform, further improving the stability of the lifting process, and also reducing the wear of the lifting cylinder. This enhances the structural stability and service life of the insulating chassis assembly and even the entire plug-in distribution box.

[0027] In one exemplary embodiment, the insulated chassis assembly further includes: a first connecting rod 202, a first elastic support 201 and a second elastic support 204 connected by the first connecting rod 202, the first connecting rod 202 being spaced apart from the first lifting cylinder 206 and the second lifting cylinder 209 respectively; a second connecting rod 207, a third elastic support 205 and a fourth elastic support 208 connected by the second connecting rod 207, the second connecting rod 207 being spaced apart from the first lifting cylinder 206 and the second lifting cylinder 209 respectively, and the second connecting rod 207 being parallel to the first connecting rod 202.

[0028] In this embodiment, the first connecting rod 202 connects the first elastic support seat 201 and the second elastic support seat 204, and the second connecting rod 207 connects the third elastic support seat 205 and the fourth elastic support seat 208. This allows the dispersed elastic support seats to form two sets of cooperative support units, enhancing the overall force continuity and structural stability of each elastic support seat. Simultaneously, the first connecting rod 202 and the second connecting rod 207 are spaced apart from the first lifting cylinder 206 and the second lifting cylinder 209, respectively, avoiding motion interference with the lifting cylinders and ensuring smooth lifting operations. Furthermore, the second connecting rod 207 is parallel to the first connecting rod 202, enabling a more uniform force distribution between the two sets of support units. This further enhances the support balance of the distribution box unit 10 in conjunction with the elastic support seats and lifting cylinders, reducing structural losses caused by uneven local force distribution and improving the overall reliability of the insulating chassis assembly.

[0029] In this embodiment, the insulating chassis assembly further includes: a third connecting rod 211, the second elastic support 204 and the third elastic support 205 are connected by the third connecting rod 211, and the third connecting rod 211 is arranged at an angle to the first connecting rod 202 and the second connecting rod 207 respectively; a fourth connecting rod 210, the first elastic support 201 and the fourth elastic support 208 are connected by the fourth connecting rod 210, the fourth connecting rod 210 is arranged at an angle to the first connecting rod 202 and the second connecting rod 207 respectively, and the fourth connecting rod 210 is arranged parallel to the third connecting rod 211.

[0030] In this embodiment, the third connecting rod 211 connects the second elastic support 204 and the third elastic support 205, and the fourth connecting rod 210 connects the first elastic support 201 and the fourth elastic support 208. This further connects the four elastic supports into an overall frame, significantly enhancing the synergistic force-bearing capacity and structural integrity of each elastic support. Simultaneously, the third connecting rod 211 and the fourth connecting rod 210 form angles with the first connecting rod 202 and the second connecting rod 207, respectively, and the fourth connecting rod 210 is parallel to the third connecting rod 211. This creates a stable, multi-directional support structure that effectively resists external force impacts and deformations from different directions. Combined with the elastic supports and the lifting cylinder, this further improves the support balance and structural rigidity of the distribution box unit 10, reduces component wear caused by localized stress concentration, and enhances the overall stability and service life of the insulating chassis assembly.

[0031] In this embodiment, the insulating chassis assembly further includes: foot 212, which includes a plurality of foot 212s, which are spaced apart along the insulating support 203, and each foot 212 is connected to the insulating support 203.

It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art.
