The application scenarios of single input and multiple output may be scenarios such as base station power distribution, active antenna processing unit, radio frequency remote processing unit, or indoor baseband processing unit, and the like, which is not limited herein. For example, the power distribution device 20 is used to power a communication device. In this embodiment, the communication device is a base station. A base station, also called a public mobile station, is a form of radio station, which refers to a radio transceiver station for information transfer between a mobile telephone terminal and a mobile communication switching center through a certain radio coverage area. Of course, in other embodiments, the communication device may also be other types of communication equipment, such as a wireless lightning arrester, a server, and the like, which is not limited herein.

Each of the power distribution devices in the related art needs to correspond to one power connection terminal, in other words, a plurality of power distribution devices are electrically connected to a plurality of power connection terminals of the power source, respectively, so that the power source supplies power to a plurality of loads. However, in a single-input and multi-output application scenario, the power supply has only one power connection, which results in that the power distribution apparatus in the related art cannot meet the usage requirement of the power supply for supplying power to multiple loads.

In view of the above, the present embodiment provides a power distribution system 10, and the power distribution system 10 at least includes at least one electrically conductive connecting element 30 and at least two power distribution devices 20.

It is understood that the number of the power distribution devices 20 may be determined according to the usage requirement, and is not particularly limited herein, for example, the number of the power distribution devices 20 may be 1, 2, 3, 4, 5, etc.

The following describes an implementation of the power distribution system 10 provided in the embodiment of the present application.

Referring to fig. 1 and 2, a power distribution system 10 according to an embodiment of the present disclosure may include: a conductive connector 30 and two power distribution devices 20. The power distribution device 20 is used to deliver power from an external power source to a load. In the embodiment of the present application, the load may be a component of the communication device that needs to be powered. Two power distribution devices 20 are stacked in a first direction (e.g., X direction in fig. 1). Referring to fig. 4 and 5, the connector 30 is located between two power distribution devices 20. Portions of the connector 30 are positioned within one of the power distribution devices 20 and electrically connected to that power distribution device 20, and portions of the connector 30 are positioned within the other power distribution device 20 and electrically connected to that power distribution device 20. The connecting member 30 electrically connects the two power distribution devices 20, so that the two power distribution devices 20 are arranged in parallel with respect to an external power source, and one of the power distribution devices 20 is electrically connected with the external power source, so that both the two power distribution devices 20 can receive power supplied by the external power source, thereby satisfying an application scenario of single-channel input and multi-channel output.

It should be noted that the number of the power distribution devices 20 is not limited to two, and may be determined according to the number of the loads, for example, the number of the loads is 5, and then the number of the power distribution devices 20 is also five.

Referring to fig. 1 and 2, power distribution system 10 further includes: a plurality of fastening plates 40. The two power distribution devices 20 may be fastened to each other by four fastening plates 40. Both ends of each fastening plate 40 are respectively screw-connected to two power distribution devices 20.

With continued reference to fig. 2, 3, and 5, the power distribution device 20 may include: a housing assembly 21, a single board module 22 and two first conductive members 23. The inner wall of the housing assembly 21 defines a receiving cavity 211 for receiving the single board module 22 and the first conductive member 23, and two connecting ports 212 are opened on the housing assembly 21, and each connecting port 212 is communicated with the receiving cavity 211. The two first conductive members 23 are insulated from each other and electrically connected to the single board module 22, and each connection port 212 is provided with one first conductive member 23. Each first conductive member 23 is adapted to electrically contact the connecting member 30 passing through the corresponding connecting port 212 of the first conductive member 23, so that the single board modules 22 of the two power distribution devices 20 are connected in parallel, and the two power distribution devices 20 are connected in parallel.

Referring to fig. 5, since the first conductive member 23 is disposed opposite to the connection port 212 corresponding to the first conductive member 23 along the first direction, when the two power distribution devices 20 are stacked along the first direction, the connection member 30 respectively passes through two adjacent connection ports 212 and is electrically contacted with the two first conductive members 23, so that the two single board modules 22 are electrically connected to the connection member 30 through the first conductive member 23, and thus the two power distribution devices 20 are connected in parallel, and therefore, any one power distribution device 20 of the two power distribution devices 20 is electrically connected to a power source, and both the two power distribution devices 20 can supply power to a load, which can be used in a single-input and multi-output application scenario. In addition, since the connecting member 30 is detachably connected to the first conductive member 23, the power distribution device 20 provided in the embodiment of the present application can also be used alone to meet different use requirements.

The single board module 22 is used to implement functions such as current conversion, current regulation, or current distribution. For example, the on-board module 22 may include at least one of a rectifier module, a high voltage direct current output module, a battery module, a DC/DC module, an AC/DC module, and a power distribution module, which are not limited herein. Specifically, the rectifier module is used for converting alternating current into direct current. The high-voltage direct current output module is used for outputting high-voltage (such as 380V) direct current. The battery module is used for storing energy and providing corresponding direct current electric energy. The AC/DC module is used for converting alternating current into direct current. The DC/DC module is used for converting the first direct-current voltage into a second direct-current voltage. The second dc voltage may be greater than the first dc voltage or less than the first dc voltage, which is determined according to actual requirements. The power distribution module is used for dividing the existing voltage into a plurality of paths and then outputting the paths. The voltages of the paths may be the same or different according to specific load requirements.

The on-board module 22 may further include: a circuit board. The circuit board is used for bearing modules such as a rectifying module, a high-voltage direct current output module, a battery module, a DC/DC module, an AC/DC module and a power distribution module. In addition, the first conductive member 23 may be mounted on a circuit board and electrically connected to the single board module 22 through the circuit board.

The number of the connection ports 212 is not limited to 2, and the larger the number of the connection ports 212 is, the more the power distribution devices 20 can be connected in parallel per power distribution device 20. In addition, when there are 2 or more connection ports 212, all the connection ports 212 may be provided on at least one surface of the housing member 21, which is not limited herein.

The shape of the connection port 212 may be a regular or irregular shape such as a circle, an ellipse, or a polygon, and is not particularly limited. For example, referring to fig. 2, the connection port 212 may be a rectangular port.

With continued reference to fig. 5, two connection ports 212 are provided on two opposite surfaces of the housing assembly 21, respectively. Wherein, two relative surfaces of this casing subassembly 21 set up along first direction is relative, so set up, can realize that a plurality of distribution device 20 stack the setting on the one hand, and on the other hand can reduce the volume size after a plurality of distribution device 20 stack.

With continued reference to fig. 5, the two connectors 212 are disposed opposite each other along the first direction, such that the two power distribution devices 20 are disposed opposite each other along the first direction, which can reduce the complexity of the connector 30 on the one hand, and the volume of the power distribution system 10 on the other hand.

The number of the first conductive members 23 is the same as that of the connection ports 212, and each first conductive member 23 is disposed corresponding to one connection port 212. Therefore, the number of the first conductive members 23 is not limited to two, and for example, the number of the first conductive members 23 may also be 3, 4, 5, etc.

With reference to fig. 5, each first conductive member 23 is exposed in the corresponding connecting port 212 of the first conductive member 23, so that the connecting member 30 can automatically and electrically contact with the first conductive member 23, thereby achieving the blind connection between the first conductive member 23 and the connecting member 30, and reducing the difficulty in electrically contacting the first conductive member 23 with the connecting member 30.

Certainly, the first conductive component 23 may also be partially exposed to the connection port 212, and thus, on the premise that the first conductive component 23 is electrically contacted with the connection component 30, the size of the opening of the connection port 212 may be reduced, which is beneficial to reducing the difficulty in sealing the connection port 212.

Fig. 6 is a schematic view illustrating a first conductive member electrically contacting a connecting member according to an embodiment of the present disclosure.

In order to achieve electrical contact of the first electrically conductive member 23 with the connection member 30, in some possible implementations, with reference to fig. 6, the first electrically conductive member 23 comprises two first electrically conductive portions 231 arranged in an insulating manner. One of the two first conductive portions 231 serves as a positive electrode, and the other serves as a negative electrode. Each first conductive part 231 is mounted on the on-board module 22 and electrically connected to the on-board module 22. The two first conductive portions 231 are electrically contacted to the connecting members 30, respectively, so that the two single board modules 22 can be connected in parallel, and the two power distribution devices 20 can be connected in parallel.

Referring to fig. 6, since the first conductive member 23 includes two first conductive portions 231, the connection member 30 also includes two second conductive portions 31 provided in an insulating manner. The two second conductive parts 31 are electrically contacted with the two first conductive parts 231, respectively, thereby achieving parallel connection of the two single board modules 22. One of the two second conductive parts 31 serves as a positive electrode, and the other serves as a negative electrode, so that the two single board modules 22 can be connected in parallel.

In some examples, the spacing between the two first conductive portions 231 may be greater than a safety threshold to achieve an insulated arrangement of the two first conductive portions 231. The safety threshold may be determined according to actual requirements, and is not particularly limited herein. In addition, the pitch between the first conductive portions 231 is a pitch in the length direction of the single board module 22 in fig. 6.

In the embodiment of the present application, the first conductive member 23 and the connecting member 30 may be inserted or abutted, so that the first conductive member 23 may automatically make electrical contact with the connecting member 30, and the first conductive member 23 may make blind contact with the connecting member 30, which may reduce the difficulty of making electrical contact between the first conductive member 23 and the connecting member 30, and may increase the speed of making electrical contact between the first conductive member 23 and the connecting member 30.

Fig. 7 is a schematic view of another first conductive member electrically contacting with a connecting member according to an embodiment of the present application.

In some possible implementations, referring to fig. 7, the first conductive member 23 may include two elastic metal clips 232 arranged in an insulating manner. Each spring metal clip 232 is mounted on a single board module 22 and electrically connected to the single board module 22. The inner wall of each of the elastic metal clips 232 defines a first notch 233, and each of the elastic metal clips 232 serves as the first conductive portion 231 in the above description. When the connecting member 30 is used with the first conductive member 23, the second conductive portion 31 is inserted into the first notch 233, and the elastic metal clip 232 abuts against the second conductive portion 31, so that the difficulty of connecting the first conductive member 23 and the connecting member 30 can be reduced, and the connection firmness of the first conductive member 23 and the connecting member 30 can be improved.

Since the elastic metal clip 232 can be elastically deformed, after the second conductive portion 31 is inserted into the first notch 233, the elastic metal clip 232 always abuts against the second conductive portion 31, which is helpful for improving the connection firmness between the first conductive portion 231 and the second conductive portion 31. In addition, the automatic insertion of the connecting member 30 into the first conductive member 23 can be realized.

Fig. 8 is a schematic view illustrating a first conductive member electrically contacting with a connecting member according to an embodiment of the present disclosure.

In some possible implementations, referring to fig. 8, the first conductive member 23 may include two elastic metal sheets 234 that are insulatively disposed. Two elastic metal sheets 234 are respectively installed on the single board module 22 and electrically connected with the single board module 22. Each of the elastic metal pieces 234 is the first conductive part 231 in the above description. When the connecting member 30 is connected to the first conductive member 23, the end surface of each second conductive portion 31 abuts against the surface of the elastic metal piece 234, helping to ensure that the first conductive member 23 is in electrical contact with the connecting member 30.

In addition, the surface area of the elastic metal sheet 234 may be larger than the end surface area of the second conductive part 31, so that the second conductive part 31 may always contact the elastic metal sheet 234 to realize the blind contact of the first conductive member 23 and the connection member 30.

Besides the elastic metal clip 232 and the elastic metal sheet 234, the first conductive part 231 may be made of a metal with magnetism, so that the first conductive part 231 is electrically contacted with the connecting part 30 and is magnetically connected with the connecting part 30, which is beneficial to improving the connection effect between the connecting part 30 and the first conductive part 23. Alternatively, fig. 9 is a cross-sectional view of another first conductive component electrically contacting with a connecting component according to an embodiment of the present application. Referring to fig. 9, the upper portion of the first conductive portion 231 is an annular structure, the lower portion is a plate-shaped structure, and the inner wall of the first conductive portion 231 defines a groove into which the second conductive portion 31 is inserted. Alternatively, fig. 10 is a schematic view illustrating that a first conductive member is electrically contacted with a connecting member according to an embodiment of the present application. The top of the first conductive part 231 is provided with a second notch 235 having a V-shaped (see fig. 10) or U-shaped longitudinal cross section, and the second conductive part 31 can be inserted into the second notch 235 and abut against the first conductive part 231.

Fig. 11 is a perspective view of a connection member engaged with a second seal ring according to an embodiment of the present disclosure.

In some possible implementations, with continued reference to fig. 5 and 11, the connecting member 30 may include a fixing plate 32 and a second conductive member 33. A portion of the fixing plate 32 is positioned within one of the connection ports 212 and another portion of the fixing plate 32 is positioned within the other connection port 212 so that the fixing plate 32 can seal the two connection ports 212 through which the connection member 30 passes. The fixing plate 32 is provided with a mounting hole penetrating through the fixing plate 32, the second conductive member 33 penetrates through the mounting hole and is fastened to the fixing plate 32, and the second conductive member 33 is insulated from the fixing plate 32. The second electrically conductive member 33 is adapted to be in electrical contact with the first electrically conductive member 23. With the connecting member 30 having such a structure, it is possible to electrically connect the two power distribution devices 20, and to seal the connection port 212 through which the second conductive member 33 passes, so as to prevent foreign substances such as water and dust from entering the accommodation cavity 211 and damaging the power distribution devices 20.

The shape of the fixing plate 32 may be the same as or different from the shape of the connection port 212, and is not particularly limited thereto. For example, referring to fig. 11, the fixing plate 32 has a rectangular shape.

With continued reference to fig. 5, the fixing plates 32 are respectively located in the two connecting ports 212, so that, in addition to simultaneously sealing the two connecting ports 212, the two housing assemblies 21 can abut against each other, and a gap between the two housing assemblies 21 in the first direction is avoided, so as to reduce the length of the power distribution system 10 in the first direction, thereby helping to reduce the volume of the power distribution system 10. With continued reference to fig. 5, to avoid entry of the fixed plate 32 into the receiving cavity 211, the inner wall of the connecting port 212 defines a stepped surface that abuts the fixed plate 32. Of course, in some examples, the fixing plate 32 may also be located between the two housing components 21 and interfere with the surfaces of the two housing components 21, respectively, while covering the two connection ports 212 to seal the two connection ports 212.

With continued reference to fig. 11, the fixing plate 32 may also be provided with first protruding portions 321 extending toward the middle of the surfaces of the two connection ports 212, and each first protruding portion 321 and the surface of the fixing plate 32 define a step surface abutting against the inner wall of the connection port 212, so that the fitting area of the fixing plate 32 and the inner wall of the connection port 212 may be increased, which may help to improve the sealing effect. It should be noted that the first protruding portion 321, and the inner wall of the connection port 212 defining the step surface abutting against the fixing plate 32 may exist at the same time, for example, as shown in fig. 5, so that the sealing effect can be further improved.

Here, the structure of the first protrusion 321 is not particularly limited. For example, the first projecting portion 321 may have a ring-like structure having the same shape as the connection port 212, or the first projecting portion 321 may have a block-like structure or a columnar structure having the same shape as the connection port 212.

The fixing plate 32 may be made of a plastic material, so that the second conductive member 33 is insulated from the fixing plate 32. In addition, the fixing plate 32 and the second conductive member 33 may be an integral structure, which helps to reduce the difficulty of manufacturing the connecting member 30. For example, in an injection molding process for forming the fixing plate 32, the second conductive member 33 is put into an injection molding liquid to form the fixing plate 32 integrally structured with the second conductive member 33.

Since the first conductive member 23 includes two first conductive portions 231 provided in an insulating manner, the second conductive member 33 is electrically contacted to the first conductive member 23. Referring to fig. 11, the second conductive member 33 includes two second conductive portions 31 disposed in an insulating manner, and the two second conductive portions 31 are respectively used for electrically contacting the two first conductive portions 231, so that the two single board modules 22 are electrically connected.

The second conductive portion 31 is made of a conductive material, for example, the material of the second conductive portion 31 is copper.

The shape of the second conductive portion 31 may be a plate-like structure, a columnar structure, or the like. For example, referring to fig. 11, the second conductive part 31 has a rectangular plate-like structure.

With continued reference to fig. 5 and 11, the power distribution device 20 may further include: a second seal ring 26. The fixing plate 32 is sleeved with two second sealing rings 26, the two second sealing rings 26 are respectively positioned in the two connecting ports 212, and each second sealing ring 26 is respectively abutted against the inner walls of the fixing plate 32 and the connecting port 212, so that the sealing effect between the fixing plate 32 and the connecting port 212 can be improved.

The second sealing ring 26 can be sleeved on the first protrusion 321, and the second sealing ring 26 can be prevented from being separated from the connection port 212 in the process of inserting the connection member 30 into the connection port 212.

Fig. 12 is a perspective view of a sealing cap engaged with a first sealing ring according to an embodiment of the present disclosure.

With continued reference to fig. 2 and 5, the power distribution device 20 further includes: and a sealing cover 24. The sealing cover 24 is used for sealing the connection port 212 when the connection member 30 is not in electrical contact with the first conductive member 23, so as to prevent foreign materials such as water, dust or steam from entering the accommodating cavity 211 to damage the power distribution device 20. Especially when the power distribution device 20 is used in an outdoor setting, it is possible to ensure that the power distribution device 20 is used properly. In addition, the sealing property can be ensured when the power distribution device 20 is used alone.

The seal cap 24 is removably connected to the housing assembly 21, and the seal cap 24 may be removed when a parallel connection of two power distribution devices 20 is desired. For example, the sealing cap 24 may be removably coupled to the housing assembly 21 by a threaded connection, snap fit, or the like.

The specific structure of the sealing cover 24 is not particularly limited herein. For example, sealing cover 24 is a plate-like structure, and sealing cover 24 may cover a surface of housing assembly 21 to seal attachment port 212. Alternatively, the sealing cover 24 covers the surface of the housing member 21, and a second protruding portion 241 (shown in fig. 12, for example) extends from the middle of the inner side surface of the sealing cover 24 contacting the surface of the housing member 21, and the second protruding portion 241 and the inner side surface of the sealing cover 24 define a step surface abutting against the inner wall of the connection port 212.

To avoid an increase in the volume of the power distribution device 20, with continued reference to fig. 5, the sealing cover 24 may also be positioned within the connecting port 212 and abut an inner wall of the connecting port 212. For example, the inner wall of the connection port 212 defines a stepped surface that abuts the seal gland 24. In addition, the second projection 241, as well as the inner wall of the interface 212, defines a stepped surface that abuts the seal cap 24, which may be present at the same time, such as shown in fig. 5.

With continued reference to fig. 5 and 12, the power distribution device 20 further includes: a first seal ring 25. The first seal ring 25 is sleeved on the seal cover 24 and is abutted against the inner wall of the connecting port 212, so that the sealing effect between the seal cover 24 and the connecting port 212 can be improved.

For example, as shown in fig. 12, the first sealing ring 25 may be sleeved on the second protrusion 241, which helps to further improve the sealing effect. The shape of the first sealing ring 25 may be determined according to the shape of the second protrusion 241, and is not particularly limited herein. For example, the second protrusion 241 has a rectangular ring shape, and correspondingly, the first seal ring 25 has a rectangular ring shape.

With continued reference to fig. 1 and 2, the housing assembly 21 is generally in the shape of a flat rectangular parallelepiped. In addition, the height direction of the housing assembly 21 is parallel to the first direction, so that two power distribution devices 20 are stacked in the height direction of the housing assembly 21, and the volume size of the power distribution system 10 can be reduced.

With continued reference to fig. 2, the housing assembly 21 may include a cover 213 and a chassis 214. Wherein, the cover 213 covers the housing 214 and is tightly connected with the housing 214, and the inner wall of the housing 214 and the inner wall of the cover 213 jointly define the accommodating cavity 211. The cover 213 and the housing 214 are respectively provided with a connection port 212, and the connection port 212 of the housing 214 and the connection port 212 of the cover 213 are oppositely arranged along the height direction of the housing assembly 21, so that the volume of the two power distribution devices 20 after being stacked can be reduced.

The cover 213 can be tightly connected with the housing 214 by a screw connection, so that the single board module 22 can be maintained or replaced.

When the number of the connection ports 212 on the housing unit 21 is two or more, the connection ports 212 are provided on at least one of the housing 214 and the cover 213. For example, in the present embodiment, the cover 213 and the cover 213 are provided with one connection port 212, respectively.

In order to improve the heat dissipation performance of the board module 22, with reference to fig. 5, the inner side surface of the cover 213 and the inner side surface of the bottom wall of the case 214 may be respectively in contact with two opposite surfaces of the board module 22, so that the size of the power distribution device 20 in the height direction may be reduced, and the heat generated by the board module 22 may be transferred to the outside of the housing assembly 21 through the case 214 or the cover 213, so as to improve the heat dissipation performance of the board module 22.

Fig. 13 is a perspective view of a cover according to an embodiment of the present disclosure.

Referring to fig. 13, the first grille part 2131 is extended from the outer surface of the cover 213, so as to increase the contact area between the cover 213 and the air in the external environment of the power distribution apparatus 20, which helps to improve the heat dissipation performance of the single board module 22. Wherein, first grid piece portion 2131 can include the first fin that the width direction interval of multi-disc edge cover 213 set up, and in addition, the first fin of polylith and cover 213 structure as an organic whole can reduce the manufacturing degree of difficulty of cover 213. Alternatively, the first grid plate may also include a plurality of first cooling fins and a plurality of second cooling fins, the plurality of first cooling fins are disposed at intervals along the width direction of the cover 213, the plurality of second cooling fins are disposed at intervals along the length direction of the cover 213, and the plurality of first cooling fins intersect with the plurality of second cooling fins. It is to be understood that the structure of the first grill sheet portion 2131 is not limited to the above two.

Fig. 14 is a perspective view of a housing according to an embodiment of the present disclosure at a first viewing angle, and fig. 15 is a perspective view of a housing according to an embodiment of the present disclosure at a second viewing angle.

Referring to fig. 14 and 15, the second grid sheet portion 2141 is extended from the outer surface of the bottom wall of the chassis 214, so as to increase the contact area between the chassis 214 and the air in the external environment of the power distribution apparatus 20, and to help increase the heat dissipation performance of the single-board module 22. The structure of the second grille plate portion 2141 may be the same as the structure of the first grille plate portion 2131, and therefore, the detailed description thereof is omitted.

With continued reference to fig. 5 and 14, the housing assembly 21 further includes: a third seal ring 215. A third gasket 215 is disposed at a junction between the cover 213 and the housing 214 to improve the sealing between the cover 213 and the housing 214. The third seal ring 215 is in contact with the lid 213 and the housing 214, respectively.

In some examples, an annular groove for partially inserting the third sealing ring 215 is formed on the surface of the casing 214 contacting with the cover 213, so as to position the third sealing ring 215 and reduce the difficulty of installing the third sealing ring 215.

With continued reference to fig. 14 and 15, to facilitate handling, mounting, and dismounting of the power distribution apparatus 20, the power distribution apparatus 20 further includes an operating member 27 provided at an end portion of one end face of the housing 214. In the embodiment of the present application, the operating member 27 is substantially rectangular frame-shaped and disposed at an angle to the housing assembly 21.

The number of the connection ports 212 in the above description is two, and the two connection ports 212 are located on two surfaces of the housing component 21 which are oppositely disposed along the first direction, however, the two connection ports 212 may not be located on two surfaces of the housing component 21 which are oppositely disposed along the first direction, as will be described below.

Fig. 16 is a cross-sectional view of another power distribution system provided in an embodiment of the present application. The power distribution system 10 shown in fig. 16 differs from the power distribution system 10 shown in fig. 5 in that: the connector 30 is not disposed between two of the power distribution devices 20, and the connector 30 is spaced from the power distribution devices 20 in a second direction (e.g., Y-direction in 16). Wherein the second direction is perpendicular to the first direction. In addition, all of the connectors 212 on each of the power distribution devices 20 are located on the same side wall of the housing assembly 21. A portion of the connection member 30 is located within one of the power distribution devices 20 and electrically connected to one of the first conductive members 23 of that power distribution device 20, a portion of the connection member 30 is located within the other power distribution device 20 and electrically connected to one of the first conductive members 23 of that power distribution device 20, and a portion of the connection member 30 is located outside of both power distribution devices 20.

Since a portion of the connection member 30 is exposed to the air, in order to ensure a normal use of the connection member 30, the connection member 30 includes a conductive body and an insulating layer, which are electrically conductive. An insulating layer covers the middle of a portion of the conductor so that both ends of the conductor are exposed, so that the connecting member 30 can be electrically contacted with the first conductive member 23. In addition, both end portions of the insulating layer are also located in the two connection ports 212, respectively.

When the first conductive member 23 includes two first conductive portions 231, in some possible implementations, the connection member 30 may include a first conductor, a second conductor, a first insulating layer, and a second insulating layer. The first insulating layer wraps the middle of the first conductor. The second insulating layer wraps the middle of the second conductor. One of the first conductor and the second conductor serves as a positive electrode conductor, and the other serves as a negative electrode conductor. The first conductor and the second conductor are in electrical contact with the two first conductive portions 231, respectively.

Of course, in some examples, the first conductor and the second conductor may be both wrapped by the third insulating layer, and the first conductor and the second conductor are disposed at an interval, so that the first conductor and the second conductor may be in electrical contact with the two first conductive portions 231 at the same time, and the difficulty of connecting the connecting member 30 to the first conductive member 23 may be reduced.

The first conductor and the second conductor may have a plate-like structure, a core wire, or the like, and are not particularly limited thereto. For example, in some examples, the first conductor and the second conductor are both copper bars, and the first conductor and the second conductor are formed in a U-shape.

The third conductive member 37 includes two body portions 371 and four connection portions 372. Both main body portions 371 are located within the seal plate 36. Opposite ends of each body portion 371 are fixedly connected to a connection end of one connection portion 372, respectively, and a free end of the connection portion 372 is adapted to pass through the connection port 212 and electrically contact the first conductive member 23. The sealing plate 36 serves to seal the connection port 212 through which the two connection portions 372 pass.

The sealing plate 36 may be detachably connected to at least one housing assembly 21 of the two power distribution devices 20 to prevent the connecting member 30 from being accidentally detached.

Similar to the fixing plate 32 in the above description, referring to fig. 17, two third protruding portions 361 inserted into the connecting port 212 may also be extended from the surface of the sealing plate 36 facing the housing component 21, and the third protruding portions 361 are inserted into the connecting port 212 and abut against the inner wall of the connecting port 212, so that the sealing effect of the sealing plate 36 may be improved, and the third conductive member 37 may be quickly electrically contacted with the first conductive member 23 by positioning the third conductive member 37 by the third protruding portions 361.

Similar to the fixing plate 32 described above, a fourth sealing ring may be provided between the sealing plate 36 and the housing assembly 21 to improve the sealing effect. For example, in the present embodiment, the fourth seal ring is fitted on the third projection 361, is positioned in the connection port 212, and abuts against the inner wall of the connection port 212.

Similar to the second conductive member 33 in the above, in the present embodiment, the third conductive member 37 may also be inserted into or abutted against the first conductive member 23. In addition, the first conductive member 23 may adopt the structure of the first conductive member 23 described above. For example, the first conductive member 23 may also include two elastic metal clips 232.

Both ends of the cable 60 are provided with first contacts 71, respectively. The bottom plate 80 is provided with a second connector 72, and the second connector 72 is electrically connected to the first conductive member 23.

Similarly, the bottom plate 80 may be located within the connection port 212, and a sealing ring may be disposed between the bottom plate 80 and the connection port 212 to improve the sealing effect. In addition, a fourth protrusion may also be extended from the surface of the bottom plate 80, and the function of the fourth protrusion is similar to that of the third protrusion 361 described above.
