[0021] Embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While certain embodiments of the present disclosure will be shown and described, it will be clear to those having ordinary skill in the art that many changes, modifications, and variations can be made therein without departing from the spirit and scope of the present disclosure. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and explanations made are to further clarify the disclosure. It should be understood that the drawings and detailed description are not intended to limit the scope of the present disclosure to the particular embodiments described, but rather, the scope of the present disclosure includes all modifications, equivalents and alternatives falling within the scope of the present disclosure.

Recitation of ranges of values herein are not intended to be a limitation, except as can be specifically claimed. There can be many

[0023] As briefly mentioned above, the existing wiring mode of the power distribution device is not only time-consuming, but also has problems such as difficult installation and disassembly. Specifically, the existing power distribution device can adopt a threaded wiring mode and a non-threaded wiring mode. The threaded wiring mode is complicated, and tools such as screwdrivers are needed, which increases the time cost of installation and disassembly. In addition, the non-threaded wiring mode includes spring connection and push-in connection.

[0024] In order to improve the wiring efficiency, the existing push-in connection module is gradually applied to the power distribution device. This wiring mode does not require the use of tools, and only needs to insert the wire directly into the wiring module. However, the push-in connection module still faces the problem of not being able to be inserted smoothly or the wiring being not firm when dealing with soft wires. Soft wires are often difficult to obtain sufficient compression in the push-in connection module due to their relatively soft structure, resulting in poor contact and affecting the normal operation of the power distribution device.

[0025] Secondly, the spring connection is a wiring mode that compresses the cable with the spring to contact the wiring terminal. The spring needs to be pressed down using a screwdriver, and the wire is inserted after which the spring is loosened to ensure stable contact. However, this wiring mode requires repeated use of tools when wiring, and the operation steps are complicated. Moreover, when disassembling the wire, it also needs to be compressed by a screwdriver, which reduces the convenience and efficiency of operation.

[0026] In addition, the existing wiring module is usually designed for a single wiring requirement and cannot achieve modular design. The installation and disassembly process of the wiring module is complex and tedious, and tools or manual operation are needed for connection. Therefore, this fixed and single wiring mode not only limits the flexibility of the power distribution device, but also increases the difficulty of maintaining and replacing the wiring module, which is difficult to meet the increasingly diversified needs of the power distribution system.

[0027] In order to solve or at least partially solve the above-mentioned problems of the existing power distribution device or other potential problems, embodiments of the present disclosure provide 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 is detachably assembled on the body, and the body is provided with a conductive terminal coupled to a main circuit. Further, the bracket of the wiring module is detachably coupled to the housing. The bracket includes at least a wiring opening for inserting a wire into the opening inside the bracket. Further, the pressing piece of the wiring module is arranged in the bracket, and the pressing piece is arranged to be 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 piece does not contact the conductive terminal, and in the locked state, the pressing piece presses the wire to conduct the wire and the main circuit through the conductive terminal.

[0028] In this way, by detachably coupling the bracket to the housing of the power distribution device, the installation and disassembly process of the wiring module can be simplified. By inserting the bracket into the corresponding position in the housing, the assembly of the wiring module can be completed without the use of complex 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.

[0029] Secondly, through the pressing piece of the wiring module, it is ensured that both hard wires and soft wires can be reliably connected through simple insertion operation. The pressing piece fixes the wire on the conductive terminal through its own elastic force after the wire is inserted, thereby solving the problem that soft wires cannot be inserted during the existing push-in wiring. In addition, the pressing piece tightly presses the wire in the locked state, ensuring the stability of the electrical connection. Even in a vibrating or temperature changing environment, 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 locked state, the pressing piece does not contact the conductive terminal, preventing the risk of electric shock.

[0030] In addition, the modular design of the wiring module facilitates quick replacement or maintenance when needed, reducing the potential risk of electrical accidents. The wiring module can be combined or expanded according to actual needs to meet the wiring needs of different power distribution devices. The modular design of the wiring module improves the versatility and adaptability of the power distribution device, allowing the selection of appropriate wiring modules for different application scenarios. Since the wiring module simplifies the wiring process, reduces the installation and maintenance time, and reduces labor costs, it improves the production efficiency and reliability of the power distribution device.

[0031] Figure 1 An exploded view of the power distribution device 100 according to some embodiments of the present disclosure is shown. Figure 2 A structural diagram of the conductive terminal 1101 and the wiring module 101 according to some embodiments of the present disclosure is shown. Figure 3 A structural diagram of the wiring module 101 according to some embodiments of the present disclosure is shown. Figure 4 A structural diagram of the pressing piece 1202 according to some embodiments of the present disclosure is shown. The example structure and working process of the wiring module 101 in the power distribution device 100 will be described below. Figures 1 to 4 The power distribution device 100 according to the embodiments of the present disclosure includes a body 110, a housing 120, and at least one wiring module 101. Through the detachable connection mode of the housing 120 and the wiring module 101, the conductive terminal 1101 is matched to realize efficient connection of the 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.

[0032] Further, the body 110 of the power distribution device 100 is built-in with a conductive terminal 1101 coupled to the main circuit. The conductive terminal 1101 is electrically conductive with the main circuit through an electrical connection. The conductive terminal 1101 can be made of a high-temperature-resistant and corrosion-resistant metal material to ensure that it does not oxidize or wear out during long-term use.

[0033] Further, the shell 120 is used to provide protection for the body 110 and is connected to the body 110 through a detachable connection. The shell 120 is detachable for easy installation and maintenance. The shell 120 includes a mounting portion 121, which is the installation position of the wiring module 101. The mounting portion 121 allows the wiring module 101 to be connected or detached from the shell 120 to adapt to different wiring needs and installation environments. The mounting portion 121 can be connected to the wiring module 101 through a buckle, a thread, or a slot structure to ensure that the wiring module 101 is stable and reliable during use.

[0034] Further, the wiring module 101 is connected to the main circuit through the wire 102. The wiring module 101 can be connected or separated from the mounting portion 121 on the shell 120 through a detachable connection. The detachable connection between the wiring module 101 and the mounting portion 121 allows the wiring module 101 to be quickly replaced or maintained when needed without the need to disassemble the entire power distribution device 100, thereby improving the maintainability and flexibility of the power distribution device 100. In other words, because the wiring module 101 and the mounting portion 121 are connected through a detachable connection, different types or specifications of wiring modules 101 can be selected for replacement or upgrading according to specific needs.

[0035] 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 the direction of insertion of the wire 102, so that the wire 102 can pass through the through hole and the wiring opening on the bracket 1201 and be introduced into the bracket 1201. After passing through the through hole, the wire 102 can abut against the conductive terminal 1101 inside the bracket 1201 through the wiring opening to achieve electrical connection between the wire 102 and the main circuit of the power distribution device 100. The size and shape of the through hole can be arranged according to different diameters of the wire 102 to avoid friction or damage to the wire 102 during insertion and ensure smooth wiring.

[0036] Further, the mounting portion 121 further comprises an unlocking hole. The unlocking hole is located in the direction of the wire 102 insertion and is aligned with the unlocking opening on the bracket 1201 of the wiring module 101. The unlocking hole is used to cooperate with the insertion operation of the unlocking piece 1203 of the wiring module 101. The unlocking piece 1203 can be partially inserted into the bracket 1201 through the unlocking hole and the unlocking opening, thereby pressing the pressing piece 1202 of the module assembly and switching the pressing piece 1202 from the locking state to the locking standby state. It should be noted that the switching can be understood as recovery. In other words, when the unlocking piece 1203 is inserted into the unlocking hole, the state of the pressing piece 1202 is changed (switched from the locking state to the locking standby state) through certain mechanical action, so that the wire 102 is taken out from between the conductive terminal 1101 and the pressing piece 1202. In addition, the unlocking hole can enable the wiring module 101 to be unlocked when needed, and the wire 102 can be disassembled, maintained or replaced.

[0037] During the installation process, first, the wiring module 101 is inserted into the through hole of the mounting portion 121, and the shell 120 is fixed to the body 110. Then, the wire 102 is inserted through the through hole and the wiring opening, and the connection between the wire 102 and the wiring module 101 is completed. After the wiring is completed, the pressing piece 1202 can be pressed by the unlocking piece 1203 to enter the locking standby state, so that the wire 102 can be separated from between the conductive terminal 1101 and the pressing piece 1202.

[0038] In some embodiments, the conductive terminal 1101 comprises a fixing portion 1102. The fixing portion 1102 is used to stably couple the conductive terminal 1101 to the body 110 of the power distribution device 100. The fixing portion 1102 can be connected to the body 110 by welding, insertion or other mechanical connection, so as 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 structure of the fixing portion 1102 can be matched with the electrical wiring and structural layout of the body 110, so that the conductive terminal 1101 can be accurately connected with the electrical components in the main circuit, and the conduction of current is ensured.

[0039] Further, the conductive terminal 1101 comprises a conducting portion 1103. The conducting portion 1103 extends from the fixing portion 1102 to the side of the wiring module 101. The conducting portion 1103 can form contact with the wire 102 via the wiring module 101 in the wiring operation, and realize 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, and ensure the contact stability and conductive performance between the wire 102 and the conductive terminal 1101. The material of the conducting portion 1103 can be a metal material with good conductivity, such as copper or copper alloy, which can withstand current load without overheating or loss during long-term use, and the embodiments of the present disclosure do not make specific limitations on this.

[0040] If the pressing piece 1202 is in the locked state, the wire 102 is pressed to the conducting portion 1103 and electrical connection is realized through the conducting portion 1103. Specifically, after the wire 102 is inserted, if the pressing piece 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 realizing current conduction between the wire 102 and the conductive terminal 1101. In this state, the contact pressure and electrical contact between the wire 102 and the conductive terminal 1101 are ensured, thereby avoiding the wire 102 from loosening or poor contact, and ensuring stable transmission of current.

[0041] In some embodiments, at least one wiring module 101 comprises a plurality of wiring modules 101. Each wiring module 101 corresponds to one conductive terminal 1101, ensuring that each wiring module 101 can provide reliable electrical connection. For example, a plurality of wiring modules 101 can correspond to a plurality of conductive terminals 1101 respectively, thereby realizing 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, further improving the adaptability and flexibility of the power distribution device 100.

[0042] In this way, the use of a plurality of wiring modules 101 can effectively improve the modularization degree of the power distribution device 100. According to specific needs, different numbers of wiring modules 101 are selected and installed, and are replaced, repaired or upgraded as needed. When a wiring module 101 fails, only the wiring module 101 needs to be replaced, without the need to replace the entire power distribution device 100 or perform complex maintenance, improving the maintainability and flexibility of the power distribution device 100. In addition, the plurality of wiring modules 101 also makes the electrical connection of the power distribution device 100 more flexible, and the number of wiring modules 101 can be increased or decreased according to actual conditions to adapt to different electrical requirements.

[0043] The following will be combined with Figure 3 and Figure 4The specific structure of the wiring module 101 will be described. In the embodiments of the present disclosure, the wiring module 101 generally comprises a bracket 1201 and a pressing piece 1202. Further, the bracket 1201 is detachably connected to the shell 120 to facilitate installation and replacement. The shape and material of the bracket 1201 can be selected according to actual application requirements, and can be made of plastic or metal and have good insulation performance. The bracket 1201 is provided with at least one wiring opening, and the 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 the gap between the wire 102 and the bracket 1201 from being too large, thereby avoiding the phenomenon of poor contact.

[0044] Further, the pressing piece 1202 is arranged in the bracket 1201 and cooperates with the wiring opening. The pressing piece 1202 can be made of elastic material. When the wire 102 is inserted into the wiring opening, the wire 102 presses the pressing piece 1202, so that the structure of the pressing piece 1202 changes, thereby pressing the wire 102 against the conductive terminal 1101 to ensure that the wire 102 is firmly abutted against the conductive terminal 1101. Specifically, the pressing piece 1202 is in a to-be-locked state and does not contact the conductive terminal 1101, allowing the wire 102 to be inserted. When the wire 102 is completely inserted and reaches a predetermined position, the wire 102 presses the pressing piece 1202, so that the pressing piece 1202 is switched from the to-be-locked state to the locked state. It should be noted that the switching can be understood as triggering. At this time, the pressing piece 1202 presses the wire 102 by elastic force, so that the wire 102 is in full contact with the conductive terminal 1101, thereby realizing conductive connection and connecting the main circuit to the wire 102 through the conductive terminal 1101.

[0045] In actual operation, the wire 102 is inserted into the wiring opening in the bracket 1201, the wire 102 presses the pressing piece 1202, so that the pressing piece 1202 is switched from the to-be-locked state to the locked state, thereby pressing the wire 102 against the conductive terminal 1101 and ensuring electrical connection between the wire 102 and the main circuit. This process does not require any additional tools or screw fixing, thereby simplifying the wiring operation. In the locked state, the pressing piece 1202 stably presses the wire 102, preventing loose contact caused by vibration or other external factors, and ensuring the safety and stability of the connection.

[0046] Further, the bracket 1201 and the shell 120 are detachably connected, so that when the wiring module 101 needs to be maintained or replaced, the operation is more convenient, and the entire power distribution equipment 100 does not need to be disassembled. Only the shell 120 needs to be disassembled, and the bracket 1201 and the pressing piece 1202 can be replaced, thereby ensuring long-term stable operation of the power distribution equipment 100.

[0047] like Figure 4 As shown, in some embodiments, the pressing member 1202 includes a coupling portion 1301, a pressing portion 1302, an abutment portion 1303, and a snap-fit ​​portion 1304. Further, the coupling portion 1301 is the part connecting the pressing member 1202 to the bracket 1201, which ensures that the pressing member 1202 can be securely fixed within the bracket 1201 and withstands the insertion pressure of the wire 102 during wiring. The coupling portion 1301 can be connected to the bracket 1201 through a snap-fit, slot, or other mechanical connection method, ensuring that the pressing member 1202 will not fall off or shift during wiring, thereby ensuring the structural stability of the entire wiring module 101.

[0048] Furthermore, the pressing part 1302 extends from the first end of the coupling part 1301 and is aligned with the direction of insertion of the wire 102 in the direction of the wiring opening. The pressing part 1302 allows the wire 102 to come into contact with and be pressed when it is inserted into the bracket 1201, thereby ensuring that the wire 102 is fixed in the bracket 1201.

[0049] Furthermore, the abutment portion 1303 extends from the second end of the coupling portion 1301 toward the conductive terminal 1101 and is located at the very end of the pressing member 1202. When the pressing member 1202 is in the locked state, the abutment portion 1303 is used to press the wire 102 toward the conductive terminal 1101, ensuring that the wire 102 and the conductive terminal 1101 are in close contact, 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 abutment portion 1303 can provide continuous pressing force to ensure wiring stability and prevent poor contact due to vibration or external force.

[0050] Furthermore, the latching portion 1304 is located between the first end of the pressing portion 1302 and the abutment portion 1303. When the pressing member 1202 is in the locked state, the latching portion 1304 can couple with the abutment portion 1303. In other words, the latching portion 1304 is used to lock the latching portion 1304 and the abutment portion 1303 together when the pressing member 1202 is in the locked state, to prevent the abutment portion 1303 from prematurely acting on the wire 102. When the wire 102 is inserted into the wiring opening and touches the pressing portion 1302, the latching portion 1304 will release the coupling with the abutment portion 1303, allowing the abutment portion 1303 and the wire 102 to move together toward the conductive terminal 1101 and eventually enter the locked state. In other words, after the coupling of the latching portion 1304 is released, the pressing member 1202 will immediately and firmly press the wire 102, ensuring the stability of the electrical connection.

[0051] In this way, the pressing piece 1202, through the cooperation of the coupling part 1301, the pressing part 1302, the abutting part 1303 and the clamping part 1304, can ensure the convenience of the wire 102 insertion during the wiring process, and provide sufficient pressure after the wire 102 is fully inserted, to ensure the firm connection between the wire 102 and the conductive terminal 1101. At the same time, the clamping part 1304 ensures smooth switching between the unlocked and locked states, improving the operation flexibility and reliability of the wiring module 101. The pressing piece 1202 can adapt to different types of wires 102, improving the safety of wiring and the stability of long-term use.

[0052] In some embodiments, the bracket 1201 includes an unlocking opening, and the wiring module 101 includes an unlocking piece 1203. The position and size of the unlocking opening can be selected according to the unlocking piece 1203, so that the unlocking piece 1203 can be partially inserted into the inside of the bracket 1201 and form a corresponding matching relationship with the pressing piece 1202 inside the bracket 1201. During wiring, the abutting part 1303 of the pressing piece 1202 contacts the conductive terminal 1101 via the wire 102, enters the locked state, thereby ensuring the stability and reliability of the wiring module 101. When the unlocking piece 1203 unlocks the wiring module 101, the unlocking opening allows the unlocking piece 1203 to be easily inserted, and the abutting part 1303 is pressed to be coupled with the clamping part 1304, thereby unlocking the wiring module 101.

[0053] In actual operation, the insertion of the unlocking piece 1203 triggers the pressing action, which presses the abutting part 1303 inside the bracket 1201 to be coupled with the clamping part 1304, thereby unlocking the wiring module 101 and removing the wire 102.

[0054] In this way, the insertion and pressing action of the unlocking piece 1203 cooperate with the pressing piece 1202 inside the bracket 1201 through the unlocking opening, which can achieve the unlocking of the wiring module 101, thereby improving the operability and maintenance convenience of the wiring module 101.

[0055] In some embodiments, the bracket 1201 further includes a mounting block 1204. The mounting block 1204 on the bracket 1201 can be a structure that at least partially surrounds the pressing piece 1202, and is designed to provide a stable mounting position for the pressing piece 1202. The mounting block 1204 can be located near the inner wall or the wiring opening of the bracket 1201, and can firmly fix the pressing piece 1202 inside the bracket 1201. The mounting block 1204 not only ensures the correct positioning of the pressing piece 1202, but also improves the structural stability and shock resistance of the wiring module 101, preventing displacement or loosening during long-term use.

[0056] In some embodiments, the presser 1202 can be integrally formed, for example, by bending, cutting, or other processes, to form the presser 1202 as a whole, avoiding the assembly process of multiple components. Such integral formation not only reduces production costs, but also improves the overall structural strength and elastic performance of the presser 1202. The material of the presser 1202 can be an engineering plastic or a metal alloy with high elasticity and wear resistance, so that it can withstand a certain pressure during wiring without deformation or fatigue. Due to its integral formation, the presser 1202 can maintain a longer service life during use and ensure the stability and reliability of the wiring through good elastic compression effect.
