Other features of the present disclosure will become readily understandable through the following description.BRIEF DESCRIPTION OF DRAWINGS

[0016] The above and other features, advantages and aspects of embodiments of the present disclosure will become more apparent with reference to the accompanying drawings and the following detailed description. In the drawings, the same or similar reference numbers represent the same or similar elements, wherein: FIG. 1 illustrates an exploded view of a power distribution device according to some embodiments of the present disclosure; FIG. 2 illustrates a schematic structural diagram of a conductive terminal and a wiring module according to some embodiments of the present disclosure; FIG. 3 illustrates a schematic structural diagram of a wiring module according to some embodiments of the present disclosure; and FIG. 4 illustrates a schematic structural diagram of a pressing member according to some embodiments of the present disclosure. DETAILED DESCRIPTION

[0017] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure may be implemented in various forms, and should not be construed as limited to embodiments set forth herein, but rather, these embodiments are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only used for illustrated purposes, and are not intended to limit the protection scope of the present disclosure.

[0018] In the description of embodiments of the present disclosure, the term "include" and the like should be understood as open-ended inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on." The term "one embodiment" or "embodiment" should be understood as "at least one embodiment." The term "some embodiments" should be understood as "at least some embodiments." Other explicit and implicit definitions may also be included below. The terms "first", "second", etc. may refer to different or identical objects. Other explicit and implicit definitions may also be included below.

[0019] As mentioned briefly above, the existing wiring method of the power distribution device is not only time-consuming, but also has problems such as installation and disassembly difficulty. Specifically, the existing power distribution device may adopt a threaded wiring method and a non-threaded wiring method. The wiring process of the threaded wiring method is cumbersome and requires tools such as screwdrivers, which not only increases the time cost of installation and disassembly. In addition, the non-threaded wiring method includes a spring connection and a push-in connection.

[0020] In order to improve the wiring efficiency, existing push-in wiring modules are gradually applied to power distribution device. This wiring method does not require the use of tools, as long as the wire is directly inserted into the wiring module. However, the push-in wiring module still faces the problem that the insertion is not smooth or the wiring is not firm when dealing with a flexible wire. Due to the relatively soft structure of the flexible wire, it is often difficult to obtain sufficient compression in the push-in wiring module, resulting in poor contact, thereby affecting a normal operation of the power distribution device.

[0021] Secondly, the spring wiring is a wiring method where a spring is used to press a cable into contact with a wiring terminal, and it is necessary to use a screwdriver to press the spring, put the wire in and then release the spring to ensure that the contact is stable. However, this wiring method needs tools to be repeatedly used during wiring, the operation steps are cumbersome, and the compression operation also needs to be performed by the screwdriver during removing the wires, thereby reducing the convenience and working efficiency of the operation.

[0022] In addition, the existing wiring modules are usually designed for a single wiring demand, and cannot realize modular design. The installation and disassembly process of the wiring module is complicated and cumbersome, requiring the use of tools or manual operation to perform connection. Therefore, such a fixed and single-purpose wiring method not only limits the flexibility of the power distribution device, but also increases the difficulty of maintaining and replacing the wiring module, and it is difficult to meet the increasingly diversified demands of the power distribution system.

[0023] In order to solve or at least partially solve the above problems or other potential problems of the power distribution device of the existing solutions, embodiments of the present disclosure provide a solution of a wiring module for a power distribution device and a power distribution device. The power distribution device includes a body and a housing, the housing being detachably mounted on the body, and the body being provided with a conductive terminal coupled to a main circuit. Further, a bracket of the wiring module is detachably coupled to the housing. The bracket includes at least a wiring opening for an insertion of a wire into an opening in the bracket. Further, a pressing member of the wiring module is arranged within the bracket, and the pressing member is pressed by the wire inserted into the bracket to switch from a to-be-locked state to a locked state. In the to-be-locked state, the pressing member is not in contact with the conductive terminal, and in the locked state, the pressing member presses the wire to conduct the wire and the main circuit via the conductive terminal.

[0024] In this way, the installation and disassembly process of the wiring module can be simplified by detachably coupling the bracket to the housing of the power distribution device. By inserting the bracket into a corresponding position in the housing, assembly of the wiring module can be completed without using complicated tools or tedious steps. This not only improves the efficiency of on-site construction, but also reduces the labor intensity during maintenance and replacement of the power distribution device.

[0025] Secondly, through the pressing member of the wiring module, it is ensured that either a solid wire or a flexible wire can achieve a reliable connection through a simple insertion operation. After the wire is inserted, the pressing member fixes the wire to the conductive terminal through its own elastic force, thereby solving the problem that the flexible wire cannot be inserted during the conventional push-in wiring. In addition, the pressing member tightly presses the wire in the locked state, ensuring the stability of the electrical connection. Even in an environment with a vibration or temperature changes, the connection will not loosen, thereby improving the operation safety of the power distribution device and ensuring the continuity and reliability of the electrical connection. In the to-be-locked state, the pressing member is not in contact with the conductive terminal, thereby preventing a risk of accidental electric shock.

[0026] In addition, the modular design of the wiring module helps to quickly replace or maintain when needed, reducing a potential risk of electrical accidents. The wiring module is combined or expanded according to actual requirements to meet wiring requirements of different power distribution device. The modular design of the wiring module improves the universality and adaptability of the power distribution device, and can select a suitable wiring module according to different application scenarios. Since the wiring module simplifies the wiring process, the installation and maintenance time is reduced, the labor cost is reduced, and meanwhile the production efficiency and reliability of the power distribution device are improved.

[0027] FIG. 1 illustrates an exploded view of a power distribution device 100 according to some embodiments of the present disclosure. FIG. 2 shows a schematic structural diagram of a conductive terminal 1101 and a wiring module 101 according to some embodiments of the present disclosure. FIG. 3 shows a schematic structural diagram of a wiring module 101 according to some embodiments of the present disclosure. FIG. 4 shows a schematic structural diagram of a pressing member 1202 according to some embodiments of the present disclosure. An example structure and a working process of the wiring module 101 in the power distribution device 100 will be described below with reference to FIG. 1 to FIG. 4. A power distribution device 100 according to embodiments of the present disclosure includes a body 110, a housing 120, and at least one wiring module 101. Through a detachable connection manner of the housing 120 and the wiring module 101, the conductive terminal 1101 is matched with the wiring module 101 to realize the efficient connection between a main circuit and the wiring module 101. The power distribution device 100 aims to improve the convenience of installation, wiring, and maintenance of the wiring module 101, while ensuring the safety and reliability of the power distribution device 100.

[0028] Further, the body 110 of the power distribution device 100 is internally provided with the conductive terminal 1101 coupled to the main circuit. The conductive terminal 1101 is electrically connected to the main circuit through an electrical connection manner. The conductive terminal 1101 may be made of a high-temperature resistant and corrosion-resistant metal material to ensure that no oxidation or degradation occurs during long-term use.

[0029] Further, the housing 120 is configured to provide protection for the body 110 and is mated with the body 110 in a detachable connection manner. The housing 120 is detachable, making installation and maintenance easier. The housing 120 includes a mounting portion 121, and the mounting portion 121 is an installation position of the wiring module 101. The mounting portion 121 enables the wiring module 101 to be connected or detached from the housing 120 to adapt to different wiring requirements and installation environments. The mounting portion 121 may be mated with the wiring module 101 through a buckle, thread or a slot structure to ensure that the wiring module 101 is stable and reliable during use.

[0030] Further, the wiring module 101 is connected to the main circuit through a wire 102. The wiring module 101 may use a detachable connection manner, and may be connected to or separated from the mounting portion 121 on the housing 120. The detachable connection manner between the wiring module 101 and the mounting portion 121 enables the wiring module 101 to be quickly replaced or maintained when needed without disassembling the entire power distribution device 100, thereby improving the maintainability and flexibility of the power distribution device 100. In other words, since the detachable connection manner is used between the wiring module 101 and the mounting portion 121, different types or specifications of wiring modules 101 may be selected for replacement or upgrade according to specific needs.

[0031] In some embodiments, the mounting portion 121 includes a through hole. The through hole is aligned with a wiring opening on the bracket 1201 of the wiring module 101 described below in an insertion direction of the wire 102, so that the wire 102 can pass through the wiring opening on the bracket 1201 through the through hole and be introduced into the bracket 1201. After passing through the through hole, the wire 102 may abut against the conductive terminal 1101 in the bracket 1201 through the wire opening, to implement electrical connection between the wire 102 and the main circuit of the power distribution device 100. The size and shape of the through hole may be arranged according to the wire 102 with different diameters, so as to avoid friction or damage of the wire 102 during an insertion process and ensure a smooth wiring process.

[0032] Further, the mounting portion 121 further includes an unlocking hole. The position of the unlocking hole is aligned with an unlocking opening on the bracket 1201 of the wiring module 101 in the insertion direction of the wire 102. The unlocking hole is used to be mated with the insertion operation of an unlocking member 1203 of the wiring module 101. The unlocking member 1203 may be partially inserted into the bracket 1201 through the unlocking hole and the unlocking opening, so that a pressing member 1202 of the wiring module is pressed, and the pressing member 1202 is switched from a locked state to a to-be-locked state. It should be noted that this switching may be understood as recovering. In other words, when the unlocking member 1203 is inserted into the unlocking hole, the state of the pressing member 1202 is changed (from the locked state to the to-be-locked state) through a certain mechanical action, so that the wire 102 is taken out between the conductive terminal 1101 and the pressing member 1202. In addition, the unlocking hole may enable the wiring module 101 to be unlocked when needed, and the wire 102 to be disassembled, maintained or replaced.

[0033] During the installation process, the wiring module 101 is first inserted into the through hole of the mounting portion 121, and the housing 120 is fixed to the body 110. Then, the wire 102 is passed through the through hole and the wiring opening to complete the connection between the wire 102 and the wiring module 101. After the wiring is completed, the pressing member 1202 can be pressed by the unlocking member 1203 to enter the to-be-locked state, so as to ensure that the wire 102 can be disengaged from between the conductive terminal 1101 and the pressing member 1202.

[0034] In some embodiments, the conductive terminal 1101 includes a fixing portion 1102. The fixing portion 1102 is configured to stably couple the conductive terminal 1101 to the body 110 of the power distribution device 100. The fixing portion 1102 may be connected to the body 110 by welding, plugging or other mechanical connection, to ensure that the conductive terminal 1101 remains stable during use of the power distribution device 100 and avoids loosening or falling off due to vibration or external force. The position and the structure of the fixing portion 1102 may be mated with the electrical wiring and the structural layout of the body 110, so that the conductive terminal 1101 can accurately dock with the electrical assembly in the main circuit to ensure a conduction of a current.

[0035] Further, the conductive terminal 1101 includes a conducting portion 1103. The conducting portion 1103 is bent and extends from the fixing portion 1102 to one side of the wiring module 101. The conducting portion 1103 can make contact with the wire 102 via the wiring module 101 during the wiring operation, and realize the electrical connection between the wire 102 and the main circuit. The conducting portion 1103 can provide a good contact angle when the wire 102 is inserted, thereby ensuring the contact stability and electrical conductivity between the wire 102 and the conductive terminal 1101. The conducting portion 1103 may be made of a metal material with good conductivity, such as copper or copper alloy, to ensure that the current load can be withstood without overheating or degradation during long-term use, which is not specifically limited in embodiments of the present disclosure.

[0036] If the pressing member 1202 is in the locked state, the wire 102 is pressed to the conducting portion 1103 and the electrical connection is achieved through the conducting portion 1103. Specifically, after the wire 102 is inserted, if the pressing member 1202 is in the locked state, the wire 102 will be pushed to the conducting portion 1103, so that the wire 102 is in close contact with the conducting portion 1103, thereby achieving a current conduction between the wire 102 and the conductive terminal 1101. In this state, contact pressure and electrical contact between the wire 102 and the conductive terminal 1101 are ensured, thereby avoiding loosening or poor contact of the wire 102 and ensuring stable transmission of the current.

[0037] In some embodiments, at least one wiring module 101 includes a plurality of wiring modules 101. Each wiring module 101 corresponds to one conductive terminal 1101, ensuring that each wiring module 101 can provide a reliable electrical connection. For example, the plurality of wiring modules 101 may respectively correspond to the plurality of conductive terminals 1101, so as to realize distribution of a plurality of electrical connection points in one power distribution device 100. This enables the power distribution device 100 to flexibly select and install the wiring module 101 according to specific needs, thereby further improving adaptability and flexibility of the power distribution device 100.

[0038] In this way, using the plurality of wiring modules 101 can effectively improve the modularity of the power distribution device 100. According to specific requirements, different numbers of wiring modules 101 are selected and installed, and replaced, repaired or upgraded as required. When a certain wiring module 101 is faulty, only the wiring module 101 needs to be replaced without replacing the entire power distribution device 100 or performing complex reparation, thereby improving maintainability and flexibility of the power distribution device 100. In addition, the plurality of wiring modules 101 further make the electrical connection of the power distribution device 100 more flexible, and the wiring module 101 can be added or removed according to the actual situation to adapt to different electrical requirements.

[0039] A specific structure of a wiring module 101 will be described below with reference to FIGS. 3 and 4. In embodiments of the present disclosure, the wiring module 101 generally includes a bracket 1201 and a pressing member 1202. Further, the bracket 1201 is detachably connected to the housing 120 to facilitate installation and replacement. The shape and material of the bracket 1201 may be selected according to actual application requirements, may be made of plastic or metal, and have good insulation performance. At least one wiring opening is provided on the bracket 1201, and a wire 102 can be inserted into the bracket 1201 from the wiring opening. The size and shape of the wiring opening are selected according to the diameter of the wire 102 to ensure stable insertion of the wire 102, while preventing excessive clearance between the wire 102 and the bracket 1201, thereby avoiding poor contact.

[0040] Further, the pressing member 1202 is arranged within the bracket 1201 and mated with the wiring opening. The pressing member 1202 may be made of an elastic material. When the wire 102 is inserted into the wire opening, the wire 102 presses the pressing member 1202 to change its structure, thereby pressing the wire 102 against the conductive terminal 1101 to ensure that the wire is firmly abutted against the conductive terminal 1101. Specifically, the pressing member 1202 is not in contact with the conductive terminal 1101 in the to-be-locked state, allowing the wire 102 to be inserted. When the wire 102 is fully inserted and reaches a predetermined position, the pressing member 1202 is pressed by the wire 102, so that the pressing member 1202 is switched from a to-be-locked state to a locked state. It should be noted that this switching may be understood as a trigger. In this case, the pressing member 1202 presses the wire 102 by using an elastic force, so that the wire 102 is fully in contact with the conductive terminal 1101, thereby implementing conductive connection, and connecting a main circuit to the wire 102 through the conductive terminal 1101.

[0041] In actual operation, the wire 102 is inserted into the wiring opening in the bracket 1201, and the pressing member 1202 is pressed through the wire 102, so that the pressing member 1202 is switched from the to-be-locked state to the locked state, thereby pressing the wire 102 against the conductive terminal 1101 to ensure the electrical connection between the wire 102 and the main circuit. This process does not require any additional tools or screws to be fixed, simplifying the wiring operation. In the locked state, the pressing member 1202 firmly presses the wire 102, preventing loosening of the contact caused by vibration or other external force factors, and ensuring the safety and stability of the connection.

[0042] Further, the bracket 1201 and the housing 120 are detachably connected, so that when the wiring module 101 needs to be maintained or replaced, the operation is simpler, and the entire power distribution device 100 does not need to be disassembled. The bracket 1201 and the pressing member 1202 can be replaced only by disassembling the housing 120, ensuring a long-term stable operation of the power distribution device 100.

[0043] As shown in FIG. 4, in some embodiments, the pressing member 1202 includes a coupling portion 1301, a pressing portion 1302, an abutting portion 1303, and a clamping portion 1304. Further, the coupling portion 1301 is a portion of the pressing member 1202 connected to the bracket 1201, which is used to ensure that the pressing member 1202 can be firmly fixed within the bracket 1201 and withstand an insertion pressure of the wire 102 during a wiring process. The coupling portion 1301 may be connected to the bracket 1201 by using a snap, a slot, or other mechanical connection manner, to ensure that the pressing member 1202 does not fall off or offset during the wiring process, thereby ensuring structural stability of the entire wiring module 101.

[0044] Further, the pressing portion 1302 extends from a first end of the coupling portion 1301 and is aligned with the wiring opening in an insertion direction of the wire 102. The pressing portion 1302 enables the wire 102 to be in contact with the pressing portion 1302 and to be pressed when the wire 102 is inserted into the bracket 1201, thereby ensuring that the wire 102 is fixed within the bracket 1201.

[0045] Further, the abutting portion 1303 extends from a second end of the coupling portion 1301 in a direction towards the conductive terminal 1101, and is located at an extreme end of the pressing member 1202. When the pressing member 1202 is in the locked state, the abutting portion 1303 is configured to press the wire 102 in the direction toward the conductive terminal 1101, so as to ensure that the wire 102 is in close contact with the conductive terminal 1101, thereby achieving an effective electrical connection between the conductive terminal 1101 and the main circuit. If the pressing member 1202 is in the locked state, the abutting portion 1303 may provide continuous pressing force, ensure the wiring stability, and prevent poor contact caused by vibration or external force.

[0046] Further, the clamping portion 1304 is located between a first end of the pressing portion 1302 and the abutting portion 1303, and the clamping portion 1304 can be coupled to the abutting portion 1303 when the pressing member 1202 is in the to-be-locked state. In other words, the clamping portion 1304 is configured to lock the clamping portion 1304 and the abutting portion 1303 together when the pressing member 1202 is in the to-be-locked state, to prevent the abutting portion 1303 from acting on the wire 102 prematurely. When the wire 102 is inserted into the wire opening and touches the pressing portion 1302, the clamping portion 1304 releases the coupling with the abutting portion 1303, allowing the abutting portion 1303 and the wire 102 to move together in the direction towards the conductive terminal 1101 and finally enter the locked state. In other words, after a coupling of the clamping portion 1304 is released, the pressing member 1202 immediately firmly presses the wire 102 to ensure the stability of the electrical connection.

[0047] In this way, through the cooperation of the coupling portion 1301, the pressing portion 1302, the abutting portion 1303 and the clamping portion 1304, during the wiring process, the pressing member 1202 can not only ensure the convenience when the wire 102 is inserted, but also provide sufficient pressure after the wire 102 is fully inserted, so as to ensure a firm connection between the wire 102 and the conductive terminal 1101. At the same time, the clamping portion 1304 ensures a smooth switching between an unlocked state and the locked state, and improves the operation flexibility and reliability of the wiring module 101. The pressing member 1202 can adapt to different types of wires 102, thereby improving the safety of wiring and the stability of long-term use.

[0048] In some embodiments, the bracket 1201 includes an unlocking opening, and the wiring module 101 includes an unlocking member 1203. The position and size of the unlocking opening may be selected according to the unlocking member 1203, so that the unlocking member 1203 can be partially inserted into the bracket 1201 from the unlocking opening and form a corresponding matting relationship with the pressing member 1202 in the bracket 1201. During the wiring process, the abutting portion 1303 of the pressing member 1202 is in contact with the conductive terminal 1101 via the wire 102 and enters the locked state, thereby ensuring the stability and reliability of the wiring module 101. When the unlocking member 1203 unlocks the wiring module 101, the unlocking opening enables the unlocking member 1203 to be easily inserted, and the abutting portion 1303 is pressed to couple with the clamping portion 1304, thereby releasing the locked state of the wiring module 101.

[0049] In actual operation, an insertion of the unlocking member 1203 triggers a pressing action, and presses the abutting portion 1303 in the bracket 1201 to couple with the clamping portion 1304, thereby unlocking the wiring module 101 and then taking out the wire 102.

[0050] In this way, the insertion and pressing action of the unlocking member 1203 is mated with the pressing member 1202 in the bracket 1201 through the unlocking opening to unlock the wiring module 101, thereby improving the operability and maintenance convenience of the wiring module 101.

[0051] In some embodiments, the bracket 1201 further includes a mounting block 1204. The mounting block 1204 on the bracket 1201 may allow the pressing member 1202 to at least partially surround, to provide a stable mounting position for the pressing member 1202. The mounting block 1204 may be located on an inner wall or near a wiring opening of the bracket 1201, and can firmly fix the pressing member 1202 in the bracket 1201. The mounting block 1204 not only ensures correct positioning of the pressing member 1202, but also improves structural stability and shock resistance of the wiring module 101, and prevents displacement or loosening in long-term use.

[0052] In some embodiments, the pressing member 1202 may be integrally formed, for example, by a process such as bending and cutting, to integrally manufacture the pressing member 1202, thereby avoiding a multicomponent assembly process. Such an integral forming not only reduces the production cost, but also improves the overall structural strength and elastic performance of the pressing member 1202. The material of the pressing member 1202 may be an engineering plastic or metal alloy with high elasticity and wear resistance, so that it can withstand a certain pressure during the wiring process without deformation or fatigue. Due to the integrally formed characteristics, the pressing member 1202 can maintain a long service life during use, and ensure the stability and reliability of the wiring through a good elastic pressing effect.

[0016] The above and other features, advantages and aspects of embodiments of the present disclosure will become more apparent with reference to the accompanying drawings and the following detailed description. In the drawings, the same or similar reference numbers represent the same or similar elements, wherein: FIG. 1 illustrates an exploded view of a power distribution device according to some embodiments of the present disclosure; FIG. 2 illustrates a schematic structural diagram of a conductive terminal and a wiring module according to some embodiments of the present disclosure; FIG. 3 illustrates a schematic structural diagram of a wiring module according to some embodiments of the present disclosure; and FIG. 4 illustrates a schematic structural diagram of a pressing member according to some embodiments of the present disclosure. DETAILED DESCRIPTION

[0017] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure may be implemented in various forms, and should not be construed as limited to embodiments set forth herein, but rather, these embodiments are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only used for illustrated purposes, and are not intended to limit the protection scope of the present disclosure.

[0018] In the description of embodiments of the present disclosure, the term "include" and the like should be understood as open-ended inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on." The term "one embodiment" or "embodiment" should be understood as "at least one embodiment." The term "some embodiments" should be understood as "at least some embodiments." Other explicit and implicit definitions may also be included below. The terms "first", "second", etc. may refer to different or identical objects. Other explicit and implicit definitions may also be included below.

[0019] As mentioned briefly above, the existing wiring method of the power distribution device is not only time-consuming, but also has problems such as installation and disassembly difficulty. Specifically, the existing power distribution device may adopt a threaded wiring method and a non-threaded wiring method. The wiring process of the threaded wiring method is cumbersome and requires tools such as screwdrivers, which not only increases the time cost of installation and disassembly. In addition, the non-threaded wiring method includes a spring connection and a push-in connection.

[0020] In order to improve the wiring efficiency, existing push-in wiring modules are gradually applied to power distribution device. This wiring method does not require the use of tools, as long as the wire is directly inserted into the wiring module. However, the push-in wiring module still faces the problem that the insertion is not smooth or the wiring is not firm when dealing with a flexible wire. Due to the relatively soft structure of the flexible wire, it is often difficult to obtain sufficient compression in the push-in wiring module, resulting in poor contact, thereby affecting a normal operation of the power distribution device.

[0021] Secondly, the spring wiring is a wiring method where a spring is used to press a cable into contact with a wiring terminal, and it is necessary to use a screwdriver to press the spring, put the wire in and then release the spring to ensure that the contact is stable. However, this wiring method needs tools to be repeatedly used during wiring, the operation steps are cumbersome, and the compression operation also needs to be performed by the screwdriver during removing the wires, thereby reducing the convenience and working efficiency of the operation.

[0022] In addition, the existing wiring modules are usually designed for a single wiring demand, and cannot realize modular design. The installation and disassembly process of the wiring module is complicated and cumbersome, requiring the use of tools or manual operation to perform connection. Therefore, such a fixed and single-purpose wiring method not only limits the flexibility of the power distribution device, but also increases the difficulty of maintaining and replacing the wiring module, and it is difficult to meet the increasingly diversified demands of the power distribution system.

[0023] In order to solve or at least partially solve the above problems or other potential problems of the power distribution device of the existing solutions, embodiments of the present disclosure provide a solution of a wiring module for a power distribution device and a power distribution device. The power distribution device includes a body and a housing, the housing being detachably mounted on the body, and the body being provided with a conductive terminal coupled to a main circuit. Further, a bracket of the wiring module is detachably coupled to the housing. The bracket includes at least a wiring opening for an insertion of a wire into an opening in the bracket. Further, a pressing member of the wiring module is arranged within the bracket, and the pressing member is pressed by the wire inserted into the bracket to switch from a to-be-locked state to a locked state. In the to-be-locked state, the pressing member is not in contact with the conductive terminal, and in the locked state, the pressing member presses the wire to conduct the wire and the main circuit via the conductive terminal.

[0024] In this way, the installation and disassembly process of the wiring module can be simplified by detachably coupling the bracket to the housing of the power distribution device. By inserting the bracket into a corresponding position in the housing, assembly of the wiring module can be completed without using complicated tools or tedious steps. This not only improves the efficiency of on-site construction, but also reduces the labor intensity during maintenance and replacement of the power distribution device.

[0025] Secondly, through the pressing member of the wiring module, it is ensured that either a solid wire or a flexible wire can achieve a reliable connection through a simple insertion operation. After the wire is inserted, the pressing member fixes the wire to the conductive terminal through its own elastic force, thereby solving the problem that the flexible wire cannot be inserted during the conventional push-in wiring. In addition, the pressing member tightly presses the wire in the locked state, ensuring the stability of the electrical connection. Even in an environment with a vibration or temperature changes, the connection will not loosen, thereby improving the operation safety of the power distribution device and ensuring the continuity and reliability of the electrical connection. In the to-be-locked state, the pressing member is not in contact with the conductive terminal, thereby preventing a risk of accidental electric shock.

[0026] In addition, the modular design of the wiring module helps to quickly replace or maintain when needed, reducing a potential risk of electrical accidents. The wiring module is combined or expanded according to actual requirements to meet wiring requirements of different power distribution device. The modular design of the wiring module improves the universality and adaptability of the power distribution device, and can select a suitable wiring module according to different application scenarios. Since the wiring module simplifies the wiring process, the installation and maintenance time is reduced, the labor cost is reduced, and meanwhile the production efficiency and reliability of the power distribution device are improved.

[0027] FIG. 1 illustrates an exploded view of a power distribution device 100 according to some embodiments of the present disclosure. FIG. 2 shows a schematic structural diagram of a conductive terminal 1101 and a wiring module 101 according to some embodiments of the present disclosure. FIG. 3 shows a schematic structural diagram of a wiring module 101 according to some embodiments of the present disclosure. FIG. 4 shows a schematic structural diagram of a pressing member 1202 according to some embodiments of the present disclosure. An example structure and a working process of the wiring module 101 in the power distribution device 100 will be described below with reference to FIG. 1 to FIG. 4. A power distribution device 100 according to embodiments of the present disclosure includes a body 110, a housing 120, and at least one wiring module 101. Through a detachable connection manner of the housing 120 and the wiring module 101, the conductive terminal 1101 is matched with the wiring module 101 to realize the efficient connection between a main circuit and the wiring module 101. The power distribution device 100 aims to improve the convenience of installation, wiring, and maintenance of the wiring module 101, while ensuring the safety and reliability of the power distribution device 100.

[0028] Further, the body 110 of the power distribution device 100 is internally provided with the conductive terminal 1101 coupled to the main circuit. The conductive terminal 1101 is electrically connected to the main circuit through an electrical connection manner. The conductive terminal 1101 may be made of a high-temperature resistant and corrosion-resistant metal material to ensure that no oxidation or degradation occurs during long-term use.

[0029] Further, the housing 120 is configured to provide protection for the body 110 and is mated with the body 110 in a detachable connection manner. The housing 120 is detachable, making installation and maintenance easier. The housing 120 includes a mounting portion 121, and the mounting portion 121 is an installation position of the wiring module 101. The mounting portion 121 enables the wiring module 101 to be connected or detached from the housing 120 to adapt to different wiring requirements and installation environments. The mounting portion 121 may be mated with the wiring module 101 through a buckle, thread or a slot structure to ensure that the wiring module 101 is stable and reliable during use.

[0030] Further, the wiring module 101 is connected to the main circuit through a wire 102. The wiring module 101 may use a detachable connection manner, and may be connected to or separated from the mounting portion 121 on the housing 120. The detachable connection manner between the wiring module 101 and the mounting portion 121 enables the wiring module 101 to be quickly replaced or maintained when needed without disassembling the entire power distribution device 100, thereby improving the maintainability and flexibility of the power distribution device 100. In other words, since the detachable connection manner is used between the wiring module 101 and the mounting portion 121, different types or specifications of wiring modules 101 may be selected for replacement or upgrade according to specific needs.

[0031] In some embodiments, the mounting portion 121 includes a through hole. The through hole is aligned with a wiring opening on the bracket 1201 of the wiring module 101 described below in an insertion direction of the wire 102, so that the wire 102 can pass through the wiring opening on the bracket 1201 through the through hole and be introduced into the bracket 1201. After passing through the through hole, the wire 102 may abut against the conductive terminal 1101 in the bracket 1201 through the wire opening, to implement electrical connection between the wire 102 and the main circuit of the power distribution device 100. The size and shape of the through hole may be arranged according to the wire 102 with different diameters, so as to avoid friction or damage of the wire 102 during an insertion process and ensure a smooth wiring process.

[0032] Further, the mounting portion 121 further includes an unlocking hole. The position of the unlocking hole is aligned with an unlocking opening on the bracket 1201 of the wiring module 101 in the insertion direction of the wire 102. The unlocking hole is used to be mated with the insertion operation of an unlocking member 1203 of the wiring module 101. The unlocking member 1203 may be partially inserted into the bracket 1201 through the unlocking hole and the unlocking opening, so that a pressing member 1202 of the wiring module is pressed, and the pressing member 1202 is switched from a locked state to a to-be-locked state. It should be noted that this switching may be understood as recovering. In other words, when the unlocking member 1203 is inserted into the unlocking hole, the state of the pressing member 1202 is changed (from the locked state to the to-be-locked state) through a certain mechanical action, so that the wire 102 is taken out between the conductive terminal 1101 and the pressing member 1202. In addition, the unlocking hole may enable the wiring module 101 to be unlocked when needed, and the wire 102 to be disassembled, maintained or replaced.

[0033] During the installation process, the wiring module 101 is first inserted into the through hole of the mounting portion 121, and the housing 120 is fixed to the body 110. Then, the wire 102 is passed through the through hole and the wiring opening to complete the connection between the wire 102 and the wiring module 101. After the wiring is completed, the pressing member 1202 can be pressed by the unlocking member 1203 to enter the to-be-locked state, so as to ensure that the wire 102 can be disengaged from between the conductive terminal 1101 and the pressing member 1202.

[0034] In some embodiments, the conductive terminal 1101 includes a fixing portion 1102. The fixing portion 1102 is configured to stably couple the conductive terminal 1101 to the body 110 of the power distribution device 100. The fixing portion 1102 may be connected to the body 110 by welding, plugging or other mechanical connection, to ensure that the conductive terminal 1101 remains stable during use of the power distribution device 100 and avoids loosening or falling off due to vibration or external force. The position and the structure of the fixing portion 1102 may be mated with the electrical wiring and the structural layout of the body 110, so that the conductive terminal 1101 can accurately dock with the electrical assembly in the main circuit to ensure a conduction of a current.

[0035] Further, the conductive terminal 1101 includes a conducting portion 1103. The conducting portion 1103 is bent and extends from the fixing portion 1102 to one side of the wiring module 101. The conducting portion 1103 can make contact with the wire 102 via the wiring module 101 during the wiring operation, and realize the electrical connection between the wire 102 and the main circuit. The conducting portion 1103 can provide a good contact angle when the wire 102 is inserted, thereby ensuring the contact stability and electrical conductivity between the wire 102 and the conductive terminal 1101. The conducting portion 1103 may be made of a metal material with good conductivity, such as copper or copper alloy, to ensure that the current load can be withstood without overheating or degradation during long-term use, which is not specifically limited in embodiments of the present disclosure.

[0036] If the pressing member 1202 is in the locked state, the wire 102 is pressed to the conducting portion 1103 and the electrical connection is achieved through the conducting portion 1103. Specifically, after the wire 102 is inserted, if the pressing member 1202 is in the locked state, the wire 102 will be pushed to the conducting portion 1103, so that the wire 102 is in close contact with the conducting portion 1103, thereby achieving a current conduction between the wire 102 and the conductive terminal 1101. In this state, contact pressure and electrical contact between the wire 102 and the conductive terminal 1101 are ensured, thereby avoiding loosening or poor contact of the wire 102 and ensuring stable transmission of the current.

[0037] In some embodiments, at least one wiring module 101 includes a plurality of wiring modules 101. Each wiring module 101 corresponds to one conductive terminal 1101, ensuring that each wiring module 101 can provide a reliable electrical connection. For example, the plurality of wiring modules 101 may respectively correspond to the plurality of conductive terminals 1101, so as to realize distribution of a plurality of electrical connection points in one power distribution device 100. This enables the power distribution device 100 to flexibly select and install the wiring module 101 according to specific needs, thereby further improving adaptability and flexibility of the power distribution device 100.

[0038] In this way, using the plurality of wiring modules 101 can effectively improve the modularity of the power distribution device 100. According to specific requirements, different numbers of wiring modules 101 are selected and installed, and replaced, repaired or upgraded as required. When a certain wiring module 101 is faulty, only the wiring module 101 needs to be replaced without replacing the entire power distribution device 100 or performing complex reparation, thereby improving maintainability and flexibility of the power distribution device 100. In addition, the plurality of wiring modules 101 further make the electrical connection of the power distribution device 100 more flexible, and the wiring module 101 can be added or removed according to the actual situation to adapt to different electrical requirements.

[0039] A specific structure of a wiring module 101 will be described below with reference to FIGS. 3 and 4. In embodiments of the present disclosure, the wiring module 101 generally includes a bracket 1201 and a pressing member 1202. Further, the bracket 1201 is detachably connected to the housing 120 to facilitate installation and replacement. The shape and material of the bracket 1201 may be selected according to actual application requirements, may be made of plastic or metal, and have good insulation performance. At least one wiring opening is provided on the bracket 1201, and a wire 102 can be inserted into the bracket 1201 from the wiring opening. The size and shape of the wiring opening are selected according to the diameter of the wire 102 to ensure stable insertion of the wire 102, while preventing excessive clearance between the wire 102 and the bracket 1201, thereby avoiding poor contact.

[0040] Further, the pressing member 1202 is arranged within the bracket 1201 and mated with the wiring opening. The pressing member 1202 may be made of an elastic material. When the wire 102 is inserted into the wire opening, the wire 102 presses the pressing member 1202 to change its structure, thereby pressing the wire 102 against the conductive terminal 1101 to ensure that the wire is firmly abutted against the conductive terminal 1101. Specifically, the pressing member 1202 is not in contact with the conductive terminal 1101 in the to-be-locked state, allowing the wire 102 to be inserted. When the wire 102 is fully inserted and reaches a predetermined position, the pressing member 1202 is pressed by the wire 102, so that the pressing member 1202 is switched from a to-be-locked state to a locked state. It should be noted that this switching may be understood as a trigger. In this case, the pressing member 1202 presses the wire 102 by using an elastic force, so that the wire 102 is fully in contact with the conductive terminal 1101, thereby implementing conductive connection, and connecting a main circuit to the wire 102 through the conductive terminal 1101.

[0041] In actual operation, the wire 102 is inserted into the wiring opening in the bracket 1201, and the pressing member 1202 is pressed through the wire 102, so that the pressing member 1202 is switched from the to-be-locked state to the locked state, thereby pressing the wire 102 against the conductive terminal 1101 to ensure the electrical connection between the wire 102 and the main circuit. This process does not require any additional tools or screws to be fixed, simplifying the wiring operation. In the locked state, the pressing member 1202 firmly presses the wire 102, preventing loosening of the contact caused by vibration or other external force factors, and ensuring the safety and stability of the connection.

[0042] Further, the bracket 1201 and the housing 120 are detachably connected, so that when the wiring module 101 needs to be maintained or replaced, the operation is simpler, and the entire power distribution device 100 does not need to be disassembled. The bracket 1201 and the pressing member 1202 can be replaced only by disassembling the housing 120, ensuring a long-term stable operation of the power distribution device 100.

[0043] As shown in FIG. 4, in some embodiments, the pressing member 1202 includes a coupling portion 1301, a pressing portion 1302, an abutting portion 1303, and a clamping portion 1304. Further, the coupling portion 1301 is a portion of the pressing member 1202 connected to the bracket 1201, which is used to ensure that the pressing member 1202 can be firmly fixed within the bracket 1201 and withstand an insertion pressure of the wire 102 during a wiring process. The coupling portion 1301 may be connected to the bracket 1201 by using a snap, a slot, or other mechanical connection manner, to ensure that the pressing member 1202 does not fall off or offset during the wiring process, thereby ensuring structural stability of the entire wiring module 101.

[0044] Further, the pressing portion 1302 extends from a first end of the coupling portion 1301 and is aligned with the wiring opening in an insertion direction of the wire 102. The pressing portion 1302 enables the wire 102 to be in contact with the pressing portion 1302 and to be pressed when the wire 102 is inserted into the bracket 1201, thereby ensuring that the wire 102 is fixed within the bracket 1201.

[0045] Further, the abutting portion 1303 extends from a second end of the coupling portion 1301 in a direction towards the conductive terminal 1101, and is located at an extreme end of the pressing member 1202. When the pressing member 1202 is in the locked state, the abutting portion 1303 is configured to press the wire 102 in the direction toward the conductive terminal 1101, so as to ensure that the wire 102 is in close contact with the conductive terminal 1101, thereby achieving an effective electrical connection between the conductive terminal 1101 and the main circuit. If the pressing member 1202 is in the locked state, the abutting portion 1303 may provide continuous pressing force, ensure the wiring stability, and prevent poor contact caused by vibration or external force.

[0046] Further, the clamping portion 1304 is located between a first end of the pressing portion 1302 and the abutting portion 1303, and the clamping portion 1304 can be coupled to the abutting portion 1303 when the pressing member 1202 is in the to-be-locked state. In other words, the clamping portion 1304 is configured to lock the clamping portion 1304 and the abutting portion 1303 together when the pressing member 1202 is in the to-be-locked state, to prevent the abutting portion 1303 from acting on the wire 102 prematurely. When the wire 102 is inserted into the wire opening and touches the pressing portion 1302, the clamping portion 1304 releases the coupling with the abutting portion 1303, allowing the abutting portion 1303 and the wire 102 to move together in the direction towards the conductive terminal 1101 and finally enter the locked state. In other words, after a coupling of the clamping portion 1304 is released, the pressing member 1202 immediately firmly presses the wire 102 to ensure the stability of the electrical connection.

[0047] In this way, through the cooperation of the coupling portion 1301, the pressing portion 1302, the abutting portion 1303 and the clamping portion 1304, during the wiring process, the pressing member 1202 can not only ensure the convenience when the wire 102 is inserted, but also provide sufficient pressure after the wire 102 is fully inserted, so as to ensure a firm connection between the wire 102 and the conductive terminal 1101. At the same time, the clamping portion 1304 ensures a smooth switching between an unlocked state and the locked state, and improves the operation flexibility and reliability of the wiring module 101. The pressing member 1202 can adapt to different types of wires 102, thereby improving the safety of wiring and the stability of long-term use.

[0048] In some embodiments, the bracket 1201 includes an unlocking opening, and the wiring module 101 includes an unlocking member 1203. The position and size of the unlocking opening may be selected according to the unlocking member 1203, so that the unlocking member 1203 can be partially inserted into the bracket 1201 from the unlocking opening and form a corresponding matting relationship with the pressing member 1202 in the bracket 1201. During the wiring process, the abutting portion 1303 of the pressing member 1202 is in contact with the conductive terminal 1101 via the wire 102 and enters the locked state, thereby ensuring the stability and reliability of the wiring module 101. When the unlocking member 1203 unlocks the wiring module 101, the unlocking opening enables the unlocking member 1203 to be easily inserted, and the abutting portion 1303 is pressed to couple with the clamping portion 1304, thereby releasing the locked state of the wiring module 101.

[0049] In actual operation, an insertion of the unlocking member 1203 triggers a pressing action, and presses the abutting portion 1303 in the bracket 1201 to couple with the clamping portion 1304, thereby unlocking the wiring module 101 and then taking out the wire 102.

[0050] In this way, the insertion and pressing action of the unlocking member 1203 is mated with the pressing member 1202 in the bracket 1201 through the unlocking opening to unlock the wiring module 101, thereby improving the operability and maintenance convenience of the wiring module 101.

[0051] In some embodiments, the bracket 1201 further includes a mounting block 1204. The mounting block 1204 on the bracket 1201 may allow the pressing member 1202 to at least partially surround, to provide a stable mounting position for the pressing member 1202. The mounting block 1204 may be located on an inner wall or near a wiring opening of the bracket 1201, and can firmly fix the pressing member 1202 in the bracket 1201. The mounting block 1204 not only ensures correct positioning of the pressing member 1202, but also improves structural stability and shock resistance of the wiring module 101, and prevents displacement or loosening in long-term use.

[0052] In some embodiments, the pressing member 1202 may be integrally formed, for example, by a process such as bending and cutting, to integrally manufacture the pressing member 1202, thereby avoiding a multicomponent assembly process. Such an integral forming not only reduces the production cost, but also improves the overall structural strength and elastic performance of the pressing member 1202. The material of the pressing member 1202 may be an engineering plastic or metal alloy with high elasticity and wear resistance, so that it can withstand a certain pressure during the wiring process without deformation or fatigue.
