[0029] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

[0030] In the description of the embodiments of the present disclosure, the term "including" and its similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". There may also be other explicit and implicit definitions hereinafter. The terms "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions hereinafter.

[0031] As briefly mentioned above, traditional drawer cabinets have problems such as complex structures, large space occupancy, high precision requirements for processing and assembly, and the integration of microswitches with other operating mechanisms. The microswitches used in traditional drawer cabinets have relatively complex structures and require multiple components to work together, thus increasing the overall complexity of the drawer cabinets. Secondly, traditional drawer cabinets occupy a large amount of space, causing layout difficulties in power distribution rooms with limited space. In addition, the function of the microswitch highly depends on the precision of processing and assembly. If the precision is insufficient, it will lead to the failure or malfunction of the switch function, affecting the reliability and safety of the drawer cabinet.

[0032] In addition, when it is necessary to combine the three-position indication function with other operating mechanisms, it is difficult for traditional microswitches to achieve integration. This limitation makes it difficult to expand and optimize the functions of the drawer cabinet, which is not conducive to meeting the increasingly complex industrial application requirements.

[0033] To solve or at least partially solve the above problems or other potential problems of the traditional drawer cabinet solutions, embodiments of the present disclosure provide a plug-in component for a drawer cabinet and a drawer cabinet solution. According to the embodiments of the present disclosure, the plug-in component includes a plug part and a socket part.

[0034] The plug part is installed at one end of the moving part of the drawer cabinet along the moving direction. The plug part includes a guiding column extending along the moving direction, and a conducting member is arranged at a preset position on the guiding column.

[0035] The socket part is fixed on the fixed part of the drawer cabinet and includes a guiding sleeve extending along the moving direction and multiple groups of contact pieces. The guiding sleeve matches the guiding column. The guiding sleeve is used to guide the sliding of the guiding column to ensure the accuracy and stability of its movement.

[0036] When the moving part of the drawer cabinet is moving, the guiding column of the plug part slides in the guiding sleeve of the socket part. According to the position of the moving part of the drawer cabinet, the conducting member on the guiding column will contact different groups of contact pieces, thereby closing the corresponding circuits to achieve position indication.

[0037] Compared with the traditional microswitch design, the plug-in component has a simple structure, reduces the use of complex components, occupies less space, is easy to integrate with other operating mechanisms, and also makes the maintenance and repair of the drawer cabinet more convenient. In addition, the reliability and stability of the drawer cabinet are improved through the sliding mechanism of the guiding column in the guiding sleeve, avoiding the requirements for processing and assembly precision. At the same time, through the contact between the conducting member and different contact pieces, the position of the moving part of the drawer cabinet can be accurately indicated, improving the operating safety of the drawer cabinet.

[0038] The following will be combined with Figures 1 to 18 to describe the exemplary structure of the drawer cabinet 100. As Figures 1 to 3As shown, in an embodiment of the present disclosure, a drawer cabinet 100 is provided. The drawer cabinet 100 is, for example, a low-voltage power distribution cabinet, and includes a fixed part 120, a moving part 110, and a plug-in component 101.

[0039] Specifically, the fixed part 120 is fixed in a power distribution room or an equipment room. The fixed part 120 provides a stable support and reference point for the entire system, and also bears various electrical components and connection devices.

[0040] Furthermore, the moving part 110 can move relative to the fixed part 120 along a predetermined moving direction A, enabling an operator to conveniently separate, test, or work on the moving part 110, thereby improving the maintainability and flexibility of the drawer cabinet 100. For example, the moving part 110 can carry switchgear or other electrical components.

[0041] Furthermore, the plug-in component 101 includes a plug part 111 fixed on the moving part 110 and a socket part 121 installed on the fixed part 120, which will be described in detail below. It can be understood that the plug-in component 101 can include the secondary plug of the drawer cabinet 100.

[0042] Thus, by combining the fixed part 120, the moving part 110, and the plug-in component 101, a low-voltage drawer cabinet 100 system with a simple structure can be formed. This can not only solve the problems existing in the traditional microswitch scheme but also improve the overall performance and reliability of the drawer cabinet 100, enabling the drawer cabinet 100 to better adapt to different application scenarios and changing industrial requirements.

[0043] In the following, the concept of the present disclosure will be described mainly based on the situation of the plug-in component 101. It should be understood that for cases with other application plug-in components 101, it is similar and will not be separately elaborated below. For the sake of convenience of description, the plug-in component 101 for the drawer cabinet 100 in the embodiment of the present disclosure will be further elaborated below.

[0044] As Figures 4 to 18 shown, the plug-in component 101 for the drawer cabinet 100 in an embodiment of the present disclosure generally includes a plug part 111 and a socket part 121. The plug-in component 101 is used to control and monitor the operating state of a circuit, transmit various control signals and data information, and enable effective communication and cooperation between different devices.

[0045] Specifically, the plug component 111 realizes the position indication function by utilizing the movement of the moving part 110 of the drawer cabinet 100. The plug component 111 is installed at one end of the moving part 110 of the drawer cabinet 100 along the moving direction A of the moving part 110. This arrangement can ensure that the plug component 111 can move together with the moving part 110, thereby accurately reflecting the position change of the moving part 110.

[0046] Furthermore, the plug component 111 includes a guide post 1111 extending along the moving direction A. The guide post 1111 is not only used to guide the moving direction A but also can be used as a carrier for the position indication function. The guide post 1111 can reflect the entire movement of the moving part 110, and its length and shape are accurately calculated to ensure that the position change of the moving part 110 is accurately reflected during the entire movement of the moving part 110. In the embodiments of the present disclosure, the length and shape of the guide post 1111 are not specifically limited.

[0047] Furthermore, a conducting member 112 is installed at a preset position on the guide post 1111. The conducting member 112 is used to form an electrical connection with the contact piece 122 on the socket component 121 when the moving part 110 moves to the preset position, which will be specifically described below.

[0048] Continue to describe the socket component 121. The socket component 121 is fixedly installed on the fixed part 120 of the drawer cabinet 100, and it cooperates with the plug component 111 to jointly complete the position indication function. The coordinated work of the socket component 121 and the plug component 111 ensures the stable and reliable operation of the drawer cabinet 100.

[0049] Furthermore, the socket component 121 includes a guide sleeve 1211 extending along the moving direction A and multiple groups of contact pieces 122. The guide sleeve 1211 can be understood as a hollow structure, and its internal dimensions and shape match those of the guide post 1111 of the plug component 111. The guide sleeve 1211 provides a stable and precise movement track for the guide post 1111 to ensure that the guide post 1111 can slide smoothly and accurately during the movement of the moving part 110 of the drawer cabinet 100. In some embodiments, in order to facilitate the guide post 1111 to enter the guide sleeve 1211, the end of the guide post 1111 can be chamfered.

[0050] Continue to describe the multiple sets of contact pieces 122. The multiple sets of contact pieces 122 are arranged in an orderly manner along the extension direction of the guide sleeve 1211, and each set of contact pieces 122 corresponds to a preset position of the moving part 110 of the drawer cabinet 100. The embodiments of the present disclosure do not specifically limit the material, shape, and elasticity of the contact pieces 122, as long as they can ensure a stable and reliable electrical connection when contacting the conducting member 112 of the plug component 111. It should be noted that the extension direction of the guide sleeve 1211 is the same as the moving direction A of the moving part 110.

[0051] When the moving part 110 of the drawer cabinet 100 is moving, the guide post 1111 of the plug component 111 will slide smoothly within the guide sleeve 1211 of the socket component 121. During this process, the conducting member 112 preset on the guide post 1111 will sequentially come into contact with different sets of contact pieces 122. Each contact corresponds to a preset position of the drawer cabinet 100.

[0052] When the conducting member 112 contacts a certain set of contact pieces 122, the circuit connected to this set of contact pieces 122 will be closed. This closed circuit will generate an electrical signal. This signal can be recognized and interpreted by the control system, so as to accurately indicate the current position of the moving part 110. For example, when the conducting member 112 contacts the innermost set of contact pieces 122, it can indicate that the drawer cabinet 100 is in the fully working position; when contacting the middle set of contact pieces 122, it can indicate the test position; and when contacting the outermost set of contact pieces 122, it can indicate that the drawer cabinet 100 is in the fully separated state.

[0053] In addition, since the socket component 121 is coupled with multiple sets of contact pieces 122, the drawer cabinet 100 has strong flexibility and expandability. By increasing or adjusting the number and position of the sets of contact pieces 122, more position indications or finer position divisions can be achieved.

[0054] In addition, since the position indication is achieved through direct physical contact, it is not easily affected by electromagnetic interference or environmental factors, thus ensuring the stability and reliability of the indication signal.

[0055] As Figures 8 to 11 shown, in some embodiments, the conducting member 112 includes a holding part 1121 and a pair of protruding parts 1122.

[0056] Specifically, the holding part 1121 is firmly embedded or fixed inside the body of the guide post 1111 to ensure that the conducting member 112 can remain stable during the frequent movement of the moving part 110 of the drawer cabinet 100 and will not be displaced or loosened.

[0057] Further, a pair of protrusions 1122 extend from the holding portion 1121. The pair of protrusions 1122 are arranged to protrude outward from the wall surface of the guide post 1111 to form contact with the external contact piece 122 (i.e., multiple groups of contact pieces 122 coupled on the guide sleeve 1211). The protrusions 1122 can be configured to protrude to a sufficient extent to ensure reliable contact with the contact piece 122. Secondly, in the embodiments of the present disclosure, the shape and material of the protrusions 1122 are not specifically limited, as long as they can ensure a stable and reliable electrical connection when contacting the contact piece 122 while minimizing wear and energy loss.

[0058] In addition, a pair of protrusions 1122 are configured as a symmetric structure relative to the holding portion 1121, so as to balance the contact force, reduce the uneven stress on the guide post 1111 during movement, and extend the service life of the entire drawer cabinet 100.

[0059] In some embodiments, a pair of protrusions 1122 are configured to be elastically coupled to the end of the holding portion 1121. Thereby, it is allowed that the protrusions 1122 have a slight deformation during the process of contacting the contact piece 122, and can adapt to different contact pressures and slight position deviations, thus ensuring a stable and reliable electrical connection.

[0060] Further, one end of the pair of protrusions 1122 away from the holding portion 1121 is configured as an open end. The open end can further increase the elasticity of the protrusions 1122, enabling them to better adapt to different contact situations. For example, the open end can allow for easier adjustment of the opening degree of the protrusions 1122 during the manufacturing process, thereby finely tuning the contact pressure.

[0061] In some embodiments, a pair of protrusions 1122 are configured as arc segments that are respectively bent outward to the outside of the conducting member 112 for contacting a group of contact pieces 122 among multiple groups of contact pieces 122. Specifically, the arc segments can increase the elasticity of the protrusions 1122, enabling them to better adapt to different contact pressures and slight position deviations. When the moving portion 110 of the drawer cabinet 100 moves, the arc segments can ensure stable and continuous contact with the contact piece 122.

[0062] In some embodiments, a non - zero angle is formed between the distal end of the protrusion 1122 and the arc segment. Specifically, the non - zero angle can form a structure similar to a barb. It can make the protrusion 1122 easier to insert or align with the corresponding group of contact pieces 122, thereby simplifying the installation process.

[0063] As Figure 11As shown, in some embodiments, the conducting member 112 is configured as an integrally formed bent member. Thereby, the number of parts can be reduced, the production process can be simplified, and the manufacturing cost can be lowered. Secondly, since there are no connection points or welding joints, integral forming can improve the structural strength and durability of the conducting member 112 and reduce the failure points.

[0064] In addition, the conducting member 112 is configured in a bent shape, which can achieve complex functional requirements while maintaining a simple structure to adapt to different application requirements. The bent shape includes a part for fixing (corresponding to the holding portion 1121 described above), and a part extending outward to form a contact surface (corresponding to the protruding portion 1122 described above). The conducting member 112 can not only ensure a stable installation but also provide sufficient elasticity to form a reliable electrical connection when contacting the contact piece 122. For example, by changing the bending angle or curvature, the contact pressure or contact area can be adjusted, thereby improving the electrical performance and mechanical reliability.

[0065] As Figures 12 to 14 shown, in some embodiments, the arrangement of multiple groups of contact pieces 122 directly corresponds to three positions of the moving part 110 of the drawer cabinet 100: the separated position, the test position, and the working position. These three positions are respectively indicated by the first group of contact pieces 1223, the second group of contact pieces 1224, and the third group of contact pieces 1225, forming a complete position indication system.

[0066] Specifically, the first group of contact pieces 1223 corresponds to the separated position, that is, the state where the moving part 110 of the drawer cabinet 100 is completely pulled out. In this position, the drawer cabinet 100 is completely disconnected from the main circuit, and maintenance or replacement operations can be safely carried out. When the conducting member 112 contacts this group of contact pieces 122, the system will identify and indicate that the drawer cabinet 100 is in the separated position, reminding the operator of the current device state.

[0067] The second group of contact pieces 1224 corresponds to the test position, that is, the intermediate state. In the test position, the main circuit of the drawer cabinet 100 is still disconnected, but the control circuit has been connected. This position allows the operator to perform functional tests or debugging without affecting the operation of the main circuit. When the conducting member 112 contacts the second group of contact pieces 1224, the system will indicate that the moving part 110 of the drawer cabinet 100 is in the transitional state.

[0068] The third group of contact pieces 1225 corresponds to the working position, that is, the state where the moving part 110 of the drawer cabinet 100 is completely inserted and put into operation. In this position, both the main circuit and the control circuit of the drawer cabinet 100 are completely connected, and the device is in a normal operating state. When the conducting member 112 contacts this group of contact pieces 122, the system will confirm that the drawer cabinet 100 is in place and ready to be put into use.

[0069] Thus, through the three sets of contact pieces 122, not only can accurate position indication be provided, but also misoperation can be effectively prevented. For example, it can ensure that the main circuit can only be closed when the drawer cabinet 100 is fully in place, or certain maintenance operations can only be carried out when it is fully separated, thereby improving the safety and reliability of the equipment.

[0070] In addition, the plug-in component 101 can also adapt to different models of drawer cabinets 100 or meet special application requirements, such as adding an indication for the intermediate transition position, by adjusting the position of the contact pieces 122 or adding additional contact piece groups.

[0071] As Figures 15 to 17 shown, in some embodiments, each set of contact pieces 122 is coupled on both sides of the guide sleeve 1211 and is connected to the corresponding circuit terminal. At the same time, by symmetrically arranging a set of contact pieces 122 on both sides, this helps to maintain the balance of the guide post 1111 during the sliding process and reduces the risk of tilting or jamming. In addition, each set of contact pieces 122 can also be connected to different circuits or control systems to achieve more complex functions or monitoring requirements.

[0072] As Figure 18 shown, in some embodiments, the contact piece 122 includes an L-shaped contact piece. The L-shaped contact piece includes: a contact section 1221 and a connection section 1222.

[0073] Specifically, the contact section 1221 is installed in the installation portion 1212 of the guide sleeve 1211 while ensuring that its surface is exposed inside the guide sleeve 1211, so that the contact section 1221 can directly contact the conducting member 112 on the moving portion 110, thereby ensuring a reliable electrical connection. Further, by embedding the contact section 1221 into the installation portion 1212, not only a firm support is provided, but also a protective effect can be achieved.

[0074] Furthermore, the connection section 1222 is a structure extending from the installation portion 1212 to the outside of the guide sleeve 1211 for connecting to the terminal of the external circuit. This can not only simplify the installation process but also facilitate subsequent maintenance and replacement.

[0075] In addition, the L-shaped contact piece has good mechanical strength and can better disperse stress to reduce the deformation or fatigue of the contact piece 122 during long-term use.

[0076] The various implementations of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed implementations. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described implementations. The choice of terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to technologies in the market, or to enable other ordinary skill in the art to understand the various implementation manners disclosed herein.
