Description

Technical Field

[0001] The present application relates to the technical field of power supply devices, and in particular to a connector and a network device. Background Art

[0002] At present, the high-power modular power supply system of network equipment adopts a single power supply mode, which can support the power demand of the entire equipment through a single power input. The cable for drawing power from the customer's room is connected to the network equipment from one side.

[0003] With the evolution of equipment, higher power distribution is needed. Single power supply can no longer support the power supply needs of the product, and dual power supplies are needed. Considering the wiring space and layout cost, dual power supplies can be two single power supplies placed on both sides of the network equipment.

[0004] The single-channel power supply includes: a power interface module and a connector connected to each other, the power interface module is connected to the network device, and the connector is used to connect the cable and the power interface module.

[0005] However, the connector outlet direction of the single-channel power supply is fixed. When a single-channel power supply device is used on both sides of the network equipment, the positive and negative poles of the power supplies on both sides are opposite, which may lead to the risk of wrong connection and safety hazards. In addition, adapters need to be designed inside the network equipment for connection, which is costly. Multiple connection will reduce the reliability of power supply and increase the cost. Summary of the invention

[0006] The embodiments of the present application provide a connector and a network device, which solve the problem of confusion that may easily arise when two single-channel power supplies are used on opposite sides of a network device.

[0007] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0008] In the first aspect of the embodiment of the present application, a connector is provided, comprising: a housing, a plurality of wiring terminals and a plurality of connectors; the housing is provided with a plurality of positioning holes, the wiring terminals are installed in the positioning holes; the housing is also provided with mounting holes connected to the plurality of positioning holes, the plurality of mounting holes are used to install cables; the wiring terminal is provided with a first connection hole corresponding to the positioning hole, the cable comprises: a cable terminal, the cable terminal is provided with a second connection hole corresponding to the positioning hole; the connector is inserted through the first connection hole, the second connection hole and the positioning hole, so that the cable terminal is electrically connected to the wiring terminal; each of the mounting holes comprises: at least two interconnected sub-mounting holes. Thus, the plurality of sub-mounting holes can be used to install cables, and when a plurality of connectors are arranged on a network device, a connector with a corresponding outlet direction (mounting hole opening direction) can be selected according to the installation position, so that the connector with a plurality of sub-mounting holes can be used in a plurality of different positions, and compared with the mounting hole with only one direction in the related art, when the connector is installed at different positions, there is no need to rotate the connector, which reduces the risk of wrong connection and reduces the safety hazard, and there is no need to design an adapter for transfer inside the network device, which reduces the cost and improves the power supply reliability.

[0009] In an optional implementation, each mounting hole includes two sub-mounting holes, and the angle between the two sub-mounting holes is 180°. Thus, two connectors of this structure can be set on opposite sides of the network device. After installation, the positive and negative power supplies of the two connectors correspond to each other, and there is no risk of wrong connection, which reduces safety hazards. In addition, there is no need to design adapters for switching inside the network device, which reduces costs and improves power supply reliability.

[0010] In an optional implementation, the mounting hole and the positioning hole are perpendicular. Thus, the mounting hole and the positioning hole can be arranged in a T-shape, avoiding interference between the cable arranged in the mounting hole and the terminal arranged in the positioning hole at a non-connected position, and making full use of the space of the connector.

[0011] In an optional implementation, the housing includes: a cover plate and a base connected to each other, the plurality of positioning holes are arranged on the base, a plurality of retaining walls are arranged on the surface of the base close to the cover plate, and the base, the plurality of retaining walls and the cover plate are arranged to form the plurality of mounting holes. Thus, by adjusting the angle of the retaining wall, the direction of the mounting hole can be adjusted, and the process is simple and easy to produce.

[0012] In an optional implementation, the connector further includes: a first rotating shaft and a second rotating shaft arranged coaxially, the base is connected to the first rotating shaft, the cover is connected to the second rotating shaft, the first rotating shaft is sleeved on the second rotating shaft, and the first rotating shaft and the second rotating shaft are rotatably connected. Thus, when the first rotating shaft and the second rotating shaft rotate relative to each other, the cover can be opened and closed relative to the base, which is convenient for installing cables and terminal blocks.

[0013] In an alternative implementation, a plurality of convex portions are provided on the first rotating shaft, and concave portions matching the convex portions are provided on the second rotating shaft. Thus, when the first rotating shaft and the second rotating shaft rotate relative to each other until the convex portions and the concave portions are matched, the contact area between the first rotating shaft and the second rotating shaft is the largest, so the friction force between the first rotating shaft and the second rotating shaft is the largest, and the cover plate and the base are in a hovering state. When the first rotating shaft and the second rotating shaft rotate relative to each other until the convex portions are not matched with the concave portions (in an intermediate state), the contact area between the first rotating shaft and the second rotating shaft is smaller, so the friction force between the first rotating shaft and the second rotating shaft is smaller. Since the friction force between the convex portions and the concave portions is increased, the hovering effect of the housing at any angle can be improved.

[0014] In an alternative implementation, the connector further includes: a fixing member, the cover plate includes: a first assembling portion, the base includes: a second assembling portion, the fixing portion includes: a first part, a second part and a third part, the third part is disposed between the first part and the second part, the second part is provided with a thread, and in the non-locked state, the third part can move axially relative to the first assembling portion within the first assembling portion; in the locked state, the second part can extend out of the first assembling portion for engaging with the second assembling portion. Thus, the fixing member can detachably connect the upper cover and the base together.

[0015] In an alternative implementation, a groove is provided on the surface of the upper cover, and the first part is disposed in the groove. Thus, it is possible to prevent the fixing portion from protruding on the surface of the upper cover, improving the flatness of the upper cover.

[0016] In an alternative implementation, a through hole is provided at the bottom of the groove, the third part passes through the through hole, the diameter of the through hole is smaller than the outer diameter of the second part, and the diameter of the through hole is smaller than the outer diameter of the first part. Thus, the fixing portion uses a non-loosening screw. In the non-locked state, the fixing member can move within the first assembling portion but will not come out of the through hole, improving the connection reliability of the fixing member.

[0017] In an alternative implementation, the groove is elongated, and the length direction of the groove is parallel to the axis of the mounting hole. Thus, by designing the groove to be elongated, for example, a waist-shaped groove (also known as a runway-shaped groove) can be used, which means that the middle is designed with an elongated shape and both ends are arc-shaped. The groove of this structure can save space in the direction perpendicular to the mounting hole, realizing a high-density design of the overall structure.

[0018] In an alternative implementation, each adjacent two of the grooves are connected by a reinforcing rib. Thus, by providing a reinforcing rib between adjacent grooves, the strength of the upper cover can be improved.

[0019] In an alternative implementation, the connector further includes: a nut, which is embedded in the positioning hole, and the connecting member is threadedly connected to the nut. Thus, the connecting member can be a bolt, with an external thread provided on the connecting member, and the connecting member can be threadedly connected to the nut. In this way, by arranging the nut in the positioning hole, the nut is snap-fitted in the positioning hole, eliminating the need to provide threads on the inner side of the positioning hole and reducing the process difficulty.

[0020] In an alternative implementation, the outer shape of the nut matches the shape of the positioning hole, and the cross-sectional shape of the positioning hole is polygonal or irregular. Thus, relative rotation of the nut with respect to the positioning hole can be avoided, ensuring stable contact between the cable terminal and the connection part, preventing shaking between the two, and enabling stable current conduction between the cable terminal and the connection terminal, that is, enabling stable electrical connection between the cable terminal and the connection terminal.

[0021] In an alternative implementation, the connection terminal includes: a fixed part and a connection part connected to each other. The first connection hole is provided on the connection part, and the fixed part is inserted into the gap between the positioning hole and the nut. Thus, the connection part is connected to the cable, and the fixed part is used to be inserted into the installation hole of the base to install the connection terminal on the base, realizing the connection between the cable and the connection terminal.

[0022] In an alternative implementation, the fixed part includes: a first fixed part and a second fixed part, and the first fixed part and the second fixed part are arranged on opposite sides of the connection part. Thus, the cross-sectional shape of the connection terminal is generally C-shaped, and the connection with the base is more stable.

[0023] In an alternative implementation, a buckle is provided on the fixed part, and the buckle is used to be snap-fitted with the outer side wall of the nut. Thus, the connection between the fixed part and the nut is more stable, preventing relative shaking between the nut and the fixed part and improving the stability of the electrical connection.

[0024] In an alternative implementation, a slot is provided on the fixed part, and the slots of every two adjacent connection terminals are snap-fitted through a snap pin. Thus, two adjacent connection terminals can be relatively fixed, preventing relative movement between adjacent positive and negative connection terminals and improving the stability of the electrical connection. At the same time, by connecting two adjacent connection terminals through the snap pin, it is possible to prevent two adjacent connection terminals from being disengaged from the positioning hole of the base.

[0025] In an alternative implementation, the end face of the end of the fixed part away from the connection part is an arc-shaped surface. Thus, compared with the end of a square shape, the arc-shaped surface has better guiding performance, enabling the connection terminal to be more conveniently inserted into the positioning hole of the base.

[0026] In an alternative implementation, the plurality of mounting holes include: a first mounting hole and a second mounting hole, and the height of the first mounting hole in the housing is different from the height of the second positioning hole in the housing. Thus, interference between the cables in the first mounting hole and the second mounting hole can be avoided.

[0027] In a second aspect of the embodiments of the present application, a network device is provided, including: a cable, a device body, and the above-mentioned connector, and the cable is connected to the main device through the connector. Thus, when the above-mentioned connector is adopted by the network device and a plurality of connectors are arranged on one network device, the corresponding connector can be selected according to the installation position. When the connectors are installed at different positions, the connector with the corresponding cable outlet direction (the opening direction of the mounting hole) can be selected. The connector with a plurality of sub-mounting holes can be used at a plurality of different positions. Compared with the mounting hole with only one direction in the related art, when the connector is installed at different positions, there is no need to rotate the connector, reducing the risk of incorrect connection, reducing potential safety hazards, and there is no need to design a transfer part inside the network device for transfer, reducing costs and improving power supply reliability.

[0028] In an alternative implementation, the main device further includes: a power interface module, the power interface module is connected to the main device, and the wiring terminal of the connector is connected to the power interface module. Thus, the power interface module can be a rectifier, which can convert the input alternating current into direct current for output.

[0029] In an alternative implementation, two connectors are provided on the device body, one of the connectors is connected to the cable through the first sub-mounting hole, and the other connector is connected to the cable through the second sub-mounting hole. Thus, at least two groups of mounting holes are arranged on the surface of the connector of the present application. When a plurality of connectors are symmetrically installed on the device body, bilateral cable outlet can be achieved without adjusting the orientation of the connector.

[0054] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0055] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "plurality" is two or more.

[0056] In addition, in the present application, orientation terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, and they may change accordingly with the change of the orientation of the components placed in the accompanying drawings.

[0057] The present application provides a network device, and the network device may be a core network, an industrial router, a transport network, an access network, a data computer room, etc.

[0058] Figure 1 Schematic diagram of a network device provided by the present application. As Figure 1 shown, the network device 10 includes: a device body 101, and a power interface module (Power Interface Unit, PIU) 102 provided on the device body 101. The power interface module 102 is used to provide a power interface to connect an external power supply to the network device 10.

[0059] In some embodiments, the power interface module 102 may be a rectifier, which can convert the input alternating current into direct current for output. For example, the power interface module 102 can convert the 220V alternating current output by the external power supply into 48V direct current and output it to the device body 101 for the device body 101 to work. The present application does not impose any restrictions on the external power supply and the device body 101. The external power supply may be any device or component that can output alternating current, and the device body 101 may be any device or component that uses direct current.

[0060] Among them, an external power supply supplies power to the network device 10 through the cable 103, and it is difficult to directly connect the cable 103 to the network device 10. In some embodiments, the network device 10 may further include: a connector 1020 for connecting the cable 103 and the internal circuit.

[0061] Figure 3 It is a schematic structural diagram of a connector. As Figure 3 shown, the connector 1020 includes: a housing 1021 and a plurality of terminal blocks 1022, and the housing 1021 is used to fix the plurality of terminal blocks 1022.

[0062] The terminal block 1022 is used to connect the cable 103 and the power interface module 102, and the plurality of terminal blocks 1022 are arranged along the X direction.

[0063] The embodiment of the present application does not limit the material of the housing 1021. In some embodiments, the housing 1021 may be made of insulating materials such as plastic and ceramic.

[0064] The embodiment of the present application does not limit the material of the terminal block 1022. In some embodiments, the terminal block 1022 may be made of conductive materials such as metal.

[0065] The embodiment of the present application does not limit the number of terminal blocks 1022 in the connector. In some embodiments, as Figure 3 shown, there are 4 terminal blocks 1022, 4 mounting holes 1024 and 4 positioning holes 1023. The terminal block 1022 includes: a first power terminal (R1﹢), a first ground terminal (R1﹣), a second power terminal (R2﹢), and a second ground terminal (R2﹣) arranged in sequence along the X direction. When connecting the cable 103 to the terminal block 1022, the cable 103 and the terminal block 1022 can be made to correspond one by one.

[0066] In some embodiments, the housing 1021 is provided with a plurality of positioning holes 1023 (through holes for installing the terminal block), and the plurality of terminal blocks 1022 are all arranged in the plurality of positioning holes 1023. The axial direction of the positioning hole 1023 is parallel to the Z direction.

[0067] The housing 1021 is also provided with a plurality of mounting holes 1024 communicating with the plurality of positioning holes 1023. The plurality of mounting holes 1024 are used to install the cable 103, and the axial direction of the mounting hole 1024 is parallel to the Y direction.

[0068] In the embodiments of the present application, the Z direction can be the thickness direction of the connector 1020, the X direction can be the length direction of the connector 1020, and the Y direction can be the width direction of the connector 1020. Among them, the Z direction, the X direction, and the Y direction are all different. For example, they can be perpendicular to each other in pairs. The length, width, and thickness in the embodiments of the present application are only for the convenience of description and do not mean any limitation on the size. For example, the length can be greater than, equal to, or less than the width. The width direction, length direction, and thickness direction of the connector 1020 can also be the width direction, length direction, and thickness direction of the connector 1020.

[0069] In some embodiments, as Figure 4 shown, the mounting hole 1024 and the positioning hole 1023 form an inverted "L" - shaped hole. The positioning hole 1023 is the "|" hole in the inverted "L" - shaped hole, and the mounting hole 1024 is the "-" hole in the inverted "L" - shaped hole. The mounting hole 1024 and the positioning hole 1023 each form an opening on the surface of the housing 1021. Among them, the opening of the positioning hole 1023 is formed, for example, on the bottom surface of the housing 1021, and the opening of the mounting hole 1024 is formed on the side surface of the housing 1021.

[0070] The embodiments of the present application do not limit the number of connectors 1020. In some embodiments, referring to Figure 1 , the number of external power supplies is one, the number of cables 103 is four, and the external power supply feeds alternating current to the power interface module 102 through the four cables 103. The number of connectors 1020 is one, and the connector 1020 feeds the output direct current to the device body 101 through four terminal blocks 1022. It should be noted that since direct current has a direction, the four cables 103 need to be connected to the positive and negative poles of the power interface module 102 respectively. Thus, only one connector 1020 needs to be set to connect the cable 103 and the power interface module 102 to supply power to the network device 10.

[0071] In other embodiments, as Figure 2 shown, the number of cables 103 is eight, and there are two or more power interface modules 102 on the network device 10 to supply power to the network device 10. The number of connectors 1020 is two, and each connector 1020 feeds the output direct current to the device body 101 through four terminal blocks 1022, which can provide higher - power power distribution. For example, there are two power interface modules 102 on the network device 10. Considering the wiring space and layout cost, the power interface modules 102 can be placed on both sides of the device body. Correspondingly, the connectors 1020 are arranged on both sides of the device body. For example, they are arranged on the left and right sides or the top and bottom sides of the device.

[0072] When two connectors 1020 are provided on the device body, wire outlets are required on both sides. In this way, when the same two connectors 1020 are used for the device body, the two connectors 1020 are arranged in central symmetry.

[0073] See Figure 2 , there are two connectors 1020 provided on the device body: a first connector 1020a and a second connector 1020b. The first connector 1020a includes: a first power terminal (R1+), a first ground terminal (R1−), a second power terminal (R2+), and a second ground terminal (R2−) arranged in sequence along the +x direction. The second connector 1020b includes: a second ground terminal (R2−), a second power terminal (R2+), a first ground terminal (R1−), and a first power terminal (R1+) arranged in sequence along the +x direction. The positive and negative of the power supply of the first connector 1020a and the second connector 1020b are opposite, there is a risk of incorrect connection, there are safety hazards, and a transfer piece needs to be designed inside the network device 10 for transfer, which is costly, and multiple transfers will result in reduced power supply reliability and high cost.

[0074] Therefore, the present application provides an improved connector 1020. At least two groups of symmetrically arranged mounting holes 1024 are provided on the surface of the connector 1020. When multiple connectors 1020 are symmetrically mounted to the device body, wire outlets on both sides can be realized without adjusting the orientation of the connectors 1020.

[0075] Figure 5 It is a schematic structural diagram of a connector provided by an embodiment of the present application. Figure 6 It is a schematic disassembled structural diagram of a connector provided by an embodiment of the present application. As Figure 5 , Figure 6 shown, the connector 1020 includes: a housing 1021 and a plurality of terminal blocks 1022.

[0076] A plurality of positioning holes 1023 for fixing the plurality of terminal blocks 1022 are provided on the housing 1021, and the axes of the plurality of positioning holes 1023 are parallel to the z direction.

[0077] Mounting holes 1024 communicating with the plurality of positioning holes 1023 are further provided on the housing 1021, and the plurality of mounting holes 1024 are used for mounting the cable 103.

[0078] In some embodiments, each mounting hole 1024 includes at least two communicating sub-mounting holes. Thus, the plurality of sub-mounting holes can all be used for mounting cables. When multiple connectors are provided on a network device, a connector with a corresponding cable outlet direction (the opening direction of the mounting hole) can be selected according to the mounting position. Therefore, a connector having multiple sub-mounting holes can be used in multiple different positions. Compared with the mounting hole having only one direction in the related art, it is not necessary to rotate the connector when mounting the connector at different positions, reducing the risk of incorrect connection, reducing potential safety hazards, and eliminating the need to design an adapter inside the network device for connection, reducing costs and improving power supply reliability.

[0079] This application does not limit the number of sub-mounting holes. Each mounting hole 1024 includes two sub-mounting holes. For example, as Figure 7 shown, each mounting hole 1024 includes a first sub-mounting hole 10241 and a second sub-mounting hole 10242 that communicate with each other. The first sub-mounting hole 10241 and the second sub-mounting hole 10242 both communicate with the positioning hole 1023. Among them, the included angle between the first sub-mounting hole 10241 and the second sub-mounting hole 10242 is greater than 0°. By way of example, the included angle between the axis of the first sub-mounting hole 10241 and the axis of the second sub-mounting hole 10242 can be 30°, 60°, 90°, 120°, etc. That is to say, the extending directions of the first sub-mounting hole 10241 and the second sub-mounting hole 10242 are different, providing more choices for the cable outlet direction.

[0080] In some embodiments, as Figure 7 shown, the included angle between the first sub-mounting hole 10241 and the second sub-mounting hole 10242 is 180°. Among them, the axes M of the first sub-mounting hole 10241 and the second sub-mounting hole 10242 are parallel to the X direction, and the axis N of the positioning hole 1023 is parallel to the Z direction. The first sub-mounting hole 10241, the second sub-mounting hole 10242, and the positioning hole 1023 form a through hole with a "T" shape. Among them, the positioning hole 1023 is the "|" hole in the "T" through hole, and the first sub-mounting hole 10241 and the second sub-mounting hole 10242 are the "-" holes in the "T" hole. Thus, it is possible to avoid interference between the cable disposed in the mounting hole and the terminal disposed in the positioning hole at non-connection positions, and make full use of the space of the connector.

[0081] Among them, as Figure 5As shown, the mounting hole 1024 is formed with two openings on the surface of the housing 1021, and the positioning hole 1023 is formed with one opening on the surface of the housing 1021. The opening of the positioning hole 1023 is formed, for example, on the bottom surface of the housing 1021, and the openings of the first sub-mounting hole 10241 and the second sub-mounting hole 10242 are formed on two opposite side surfaces of the housing 1021. The opening of the first sub-mounting hole 10241 is formed on the side surface of the housing 1021 along the positive Y-axis direction, and the opening of the second sub-mounting hole 10242 is formed on the side surface of the housing 1021 along the negative Y-axis direction.

[0082] Therefore, two connectors adopting the above structure can be arranged on opposite sides of the network device. After installation, the two connectors are arranged axially symmetrically. One of the connectors can be connected to the cable through the first sub-mounting hole, and the other can be connected to the cable through the second sub-mounting hole. There is no need to rotate the connector to achieve line output on both sides of the network device, which reduces the risk of wrong connection and reduces safety hazards. In addition, there is no need to design adapters for connection inside the network device, which reduces costs and improves power supply reliability.

[0083] In other embodiments, the structure of the positioning hole 1023 can refer to the above description, and the mounting hole 1024 may include: a first sub-mounting hole 10241, a second sub-mounting hole 10242 and a third sub-mounting hole (not shown in the figure), the first sub-mounting hole 10241, the second sub-mounting hole 10242 and the third sub-mounting hole are all connected, and the angle between the axis of the first sub-mounting hole 10241, the axis of the second sub-mounting hole 10242 and the axis of the third sub-mounting hole is greater than 0°. For example, the angle between the axis of the first sub-mounting hole 10241 and the axis of the second sub-mounting hole 10242 can be 30°, 60°, 90°, 120°, etc., and the angle between the axis of the third sub-mounting hole and the axis of the second sub-mounting hole 10242 can be 30°, 60°, 90°, 120°, etc., that is, the first sub-mounting hole 10241, the second sub-mounting hole 10242 and the third sub-mounting hole have different extension directions, providing more options for the outlet direction.

[0084] The present application does not impose any restrictions on the number and angle of the mounting holes 1024 . The number of mounting holes 1024 and the angles between adjacent mounting holes 1024 may be selected according to the shape of the shell 1021 , all of which fall within the protection scope of the present application.

[0085] For example, see Figure 8, the connector 1020 can be used for a network device 10 powered on both the left and right sides. There are two connectors 1020 on the device body 101: a first connector 1020a and a second connector 1020b. The first connector 1020a includes: a first power terminal (R1﹢), a first ground terminal (R1﹣), a second power terminal (R2﹢), and a second ground terminal (R2﹣) arranged in sequence along the positive X-axis direction, and are respectively connected to the cable 103 through second sub-mounting holes with openings on the side surface of the housing along the negative Y-axis direction. The second connector 1020b includes: a first power terminal (R1﹢), a first ground terminal (R1﹣), a second power terminal (R2﹢), and a second ground terminal (R2﹣) arranged in sequence along the positive X-axis direction, and are respectively connected to the cable 103 through first sub-mounting holes with openings on the side surface of the housing along the negative Y-axis direction. The positive and negative electrode arrangement sequences of the second connector 1020b and the first connector 1020a are the same, and the two are arranged in axial symmetry. During installation, the positive and negative power supplies of the left and right connectors 1020 can be made to face each other one by one, without the risk of incorrect connection, reducing potential safety hazards. Moreover, there is no need to design an adapter inside the network device 10 for connection, reducing costs and improving power supply reliability.

[0086] In some other embodiments, such as Figure 9 shown, the connector 1020 can also be used for a network device 10 powered on both the upper and lower sides. There are two connectors 1020 on the device body 101: a first connector 1020a and a second connector 1020b. The first connector 1020a includes: a first power terminal (R1﹢), a first ground terminal (R1﹣), a second power terminal (R2﹢), and a second ground terminal (R2﹣) arranged in sequence along the positive Y-axis direction. The second connector 1020b includes: a first power terminal (R1

[0087] ﹢), a first ground terminal (R1﹣), a second power terminal (R2﹢), and a second ground terminal (R2﹣) arranged in sequence along the positive Y-axis direction. The positive and negative electrode arrangement sequences of the second connector 1020b and the first connector 1020a are the same. During installation, the positive and negative power supplies of the upper and lower connectors 1020 can be made to face each other one by one, without the risk of incorrect connection, reducing potential safety hazards. Moreover, there is no need to design an adapter inside the network device 10 for connection, reducing costs and improving power supply reliability.

[0088] In this embodiment, the mounting hole 1024 of the first connector 1020a includes: a first sub-mounting hole 10241 and a second sub-mounting hole 10242, and the angle between the axis of the first sub-mounting hole 10241 and the axis of the second sub-mounting hole 10242 is 180°. The first connector and the second connector can be installed on opposite sides of the network device 10. After installation, the positive and negative power sources of the second connector 1020b and the first connector 1020a correspond to each other, and there is no risk of wrong connection, which reduces safety hazards, and there is no need to design an adapter for switching inside the network device 10, which reduces costs and improves power supply reliability.

[0089] Of course, in other embodiments, such as Figure 10 , Figure 11 As shown, the connector 1020 can also be used for a single-side powered network device 10. This application does not limit this.

[0090] The present embodiment of the application does not limit the structure of the housing 1021 of the connector 1020. In some embodiments, Figure 6 As shown, the housing 1021 includes two parts: a cover plate 1025 and a base 1026 connected to each other. Figure 6 The structure of the housing 1021 is described by taking FIG. 1021 as an example.

[0091] See also Figure 6 The base 1026 includes a main body 10261, a first positioning portion 10262, a second positioning portion 10263, a first assembly portion 10264 and a retaining wall 10265. The first positioning portion 10262 and the second positioning portion 10263 are fixedly connected to one side of the main body 10261, and the retaining wall 10265 and the first assembly portion 10264 are fixedly connected to the other side of the main body 10261.

[0092] The cover plate 1025 includes a first surface facing away from the base 1026 and a second surface close to the base 1026. When the cover plate 1025 is covered on the base 1026, the first surface of the base 1026, the first surface of the cover plate 1025 and the retaining wall 10265 are arranged to form a plurality of mounting holes 1024.

[0093] In this embodiment, the cover plate 1025 includes: a second assembly portion 10251 , and the second assembly portion 10251 corresponds to the first assembly portion 10264 .

[0095] The main body part 10261 includes a first surface facing the cover plate 1025 and a second surface disposed opposite to the first surface. The retaining wall 10265 and the first assembly part 10264 are fixedly connected to the first surface of the main body part 10261. In this embodiment, there are multiple retaining walls 10265, and the multiple retaining walls 10265 are arranged at intervals in the X direction and protrude from the first surface of the main body part 10261 in the Z direction.

[0096] Wherein, the Z direction is different from the X direction. In this embodiment, the Z direction is perpendicular to the X direction.

[0097] The first positioning part 10262 is fixedly connected to the second surface of the main body part 10261. The first positioning part 10262 protrudes from the second surface of the main body part 10261 in the negative Z-axis direction.

[0098] The second positioning part 10263 is fixedly connected to the second surface of the main body part 10261. In this embodiment, the second positioning part 10263 is located on the side of the first positioning part 10262 facing the positive X-axis direction and is spaced from the first positioning part 10262. The second positioning part 10263 protrudes from the second surface of the main body part 10261 in the negative Z-axis direction.

[0099] The first assembly part 10264 is fixedly connected to the first surface of the main body part 10261. In this embodiment, the number of the first assembly parts 10264 is two, and the two first assembly parts are spaced from each other. In the Y-axis direction, the above-mentioned retaining wall 10265 is provided between the two first assembly parts 10264. The assembly part protrudes from the first surface of the main body part 10261 in the Z-axis direction. The first assembly part 10264 is provided with a second fixing hole, and the opening of the first fixing hole is located at the end surface of the assembly part facing away from the main body part 10261. The first fixing hole extends in the Z-axis direction. Among them, the inner wall of the first fixing hole is provided with threads.

[0100] The second assembly part 10251 is fixedly connected to the second surface of the cover plate 1025. In this embodiment, the number of the second assembly parts 10251 is two, and the two second assembly parts 10251 are spaced from each other. The second assembly part 10251 protrudes from the second surface of the cover plate 1025 in the Z-axis direction. The second assembly part 10251 is provided with a second fixing hole, and the opening of the second fixing hole is located at the end surface of the assembly part facing away from the cover plate 1025. The second fixing hole extends in the Z-axis direction.

[0101] In order to increase the connection stability between the cover plate 1025 and the base 1026, in some embodiments, the connector 1020 further includes: a fixing member 1027. Figure 12 It is a top view of the cover plate 1025. As Figure 12 shown, the fixing member 1027 is arranged on the cover plate 1025, and the fixing member 1027 can be used to connect the cover plate 1025 and the base 1026.

[0102] In this embodiment, see Figure 12 The number of the fixing members 1027 is two, and the two fixing members 1027 are arranged along the Y-axis direction.

[0103] In order to avoid interference between the multiple fixing members 1027 and the cable 103 , the projection of the mounting hole 1024 for mounting the cable 103 on the cover plate 1025 and the projection of the first assembly portion 10264 for mounting the fixing member 1027 on the cover plate 1025 may be staggered.

[0104] For example, the cable 103 is inserted into the mounting hole 1024 along the Y direction, and the fixing members 1027 are arranged in sequence along the Y direction, that is, a plurality of fixing members 1027 can be arranged between two adjacent mounting holes 1024. Thus, interference between the cable 103 and the fixing members 1027 can be avoided, and the space of the connecting member 1029 can be fully utilized.

[0105] The material of the fixing member 1027 may be plastic. In other embodiments, the material of the fixing member 1027 may also be other insulating dielectrics, which is not specifically limited in the present application.

[0106] During assembly, the fixing member 1027 is inserted through the second assembly portion 10251 and the first assembly portion 10264 to connect the cover plate 1025 and the base 1026. Next, the structure of the fixing member 1027 is described by taking the fixing member 1027 being installed on the first assembly portion 10264 and the second assembly portion 10251 as an example.

[0107] Figure 13 This is a schematic diagram of the structure of a fixing member provided in an embodiment of the present application. Figure 13 As shown, the fixing member 1027 includes a first portion 1027a and a second portion 1027b, wherein the second portion 1027b is located on the side of the first portion 1027a facing the negative direction of the Z axis and is fixedly connected to the first portion 1027a. Along the Y axis, the width of the first portion 1027a is greater than the width of the second portion 1027b.

[0108] Figure 14 for Figure 12 The AA section view in Figure 14As shown, the second part 1027b is used to connect with the base 1026. Specifically, the outer surface of the second part 1027b is provided with threads. Through the threaded connection between the threads of the second part 1027b and the first assembly part 10264, the threaded connection between the second part 1027b and the first assembly part 10264 is realized. Rotate the first part 1027a along the threaded direction of the second part 1027b, and the first part 1027a can move along the Z-axis direction towards the base 1026 with the second part 1027b and abut against the first assembly part 10264, so that the fixing part 1027 is stably installed on the first assembly part 10264, that is, the fixing part 1027 is stably installed on the base 1026.

[0109] Since in the Y-axis direction, the width dimension of the first part 1027a is greater than the width dimension of the second part 1027b, the first part 1027a can play a role in limiting, which is convenient for the assembly between the fixing part 1027 and the housing 1021 and improves the assembly effect. In other embodiments, in the Y-axis direction, the width dimension of the first part 1027a may also be equal to or less than the width dimension of the second part 1027b, and the present application does not make any limitations in this regard.

[0110] In some embodiments, the fixing part 1027 can adopt a non-loosening screw.

[0111] In this embodiment, the fixing part 1027 further includes: a third part 1027c, the third part 1027c is arranged between the first part 1027a and the second part 1027b, the third part 1027c is a non-threaded part, and the non-threaded part refers to the part where no external thread is formed. The outer diameter of the third part 1027c is smaller than the outer diameter of the second part 1027b, and the outer diameter of the third part 1027c is smaller than the outer diameter of the first assembly part 10264, so that in the non-locked state, the third part 1027c can move axially relative to the first assembly part 10264, and in the locked state, the second part 1027b of the screw can extend out of the first assembly part 10264 for engaging with the second assembly part 10251.

[0112] Exemplarily, the fixing member 1027 is a screw, and the fixing member 1027 includes: a first portion 1027a (nut), a second portion 1027b, and a third portion 1027c (screw rod). Among them, the third portion 1027c is disposed between the first portion 1027a and the second portion 1027b. The second portion 1027b is a threaded portion, and the third portion 1027c is a non-threaded portion. The second fitting portion 10251 is sleeved on the third portion 1027c. The outer diameter of the non-threaded portion is smaller than the outer diameter of the threaded portion, and the outer diameter of the threaded portion is smaller than the outer diameter of the first fitting portion 10264, so that the non-threaded portion can move axially relative to the first fitting portion 10264 in the non-locked state, and the threaded portion of the screw rod can protrude out of the second fitting portion 10251 in the locked state for engaging with the first fitting portion 10264, so that the cover plate 1025 and the base 1026 are connected together.

[0113] In some embodiments, for installing the fixing member 1027. As Figure 6 shown, a plurality of grooves 10252 can be provided on the cover plate 1025, and the Figure 13 first portion 1027a (nut) in the [] can be disposed in the groove 10252.

[0114] In this way, it is possible to prevent the nut from protruding on the surface of the cover plate 1025, improving the flatness of the surface of the cover plate 1025.

[0115] In some embodiments, as Figure 15 shown, a through hole is provided at the bottom of the groove 10252, and the third portion 1027c (non-threaded portion) passes through the through hole. The aperture of the through hole is smaller than the outer diameter of the second portion 1027b (threaded portion), and the aperture of the through hole is smaller than the outer diameter of the first portion 1027a (nut). In this way, the non-threaded portion cannot pass through the through hole, so that when the fixing member 1027 moves axially relative to the first fitting portion 10264 in the non-locked state, the fixing member 1027 cannot escape from the through hole.

[0116] To reduce the occupation of the space in the X direction by the groove 10252, the groove 10252 can be designed to be elongated. For example, a kidney-shaped groove (also called a runway-shaped groove) as Figure 15 shown can be adopted, which means that the middle is designed to be elongated and both ends are arc-shaped.

[0117] Exemplarily, the length direction of the groove 10252 can be parallel to the Y direction. The groove 10252 with such a structure can save space and realize a high-density design of the overall structure.

[0118] In some embodiments, to increase the strength of the cover plate 1025, a reinforcing rib 10253 can also be provided between two adjacent grooves 10252, so that every two adjacent grooves 10252 are connected by the reinforcing rib 10253.

[0119] The reinforcing rib 10253 is fixedly connected to the first surface of the cover plate 1025. In this embodiment, there may be one reinforcing rib 10253, which extends in the X direction and protrudes from the first surface of the cover plate 1025 in the z direction. In this way, the strength of the cover plate 1025 can be increased. The reinforcing rib 10253 and the cover plate 1025 can be integrally formed to simplify the manufacturing process of the cover plate 1025 and ensure the overall strength of the cover plate 1025.

[0120] The embodiment of the present application does not limit the connection manner between the cover plate 1025 and the base 1026. In the above embodiment, the cover plate 1025 can be connected to the base 1026 through the fixing member 1027. To improve the connection stability between the cover plate 1025 and the base 1026, a rotating shaft can also be provided at one end of the cover plate 1025 and the base 1026, so that the cover plate 1025 and the base 1026 can be rotatably connected.

[0121] Figure 16 For Figure 6 the schematic structural diagram when the rotating shaft in Figure 17 is in the hovering state. Figure 6 For Figure 6 、 Figure 16 As shown in

[0122] The connector 1020 further includes: a first rotating shaft 10266 and a second rotating shaft 10254 arranged coaxially. The housing 1021 may include a cover plate 1025, a base 1026, and the first rotating shaft 10266 and the second rotating shaft 10254 connecting the cover plate 1025 and the base 1026. The base 1026 is connected to the first rotating shaft 10266, the cover plate 1025 is connected to the second rotating shaft 10254, the first rotating shaft 10266 is sleeved on the second rotating shaft 10254, and the first rotating shaft 10266 and the second rotating shaft 10254 are rotatably connected. In this way, the cover plate 1025 and the base 1026 achieve rotational cooperation through the first rotating shaft 10266 and the second rotating shaft 10254, so that the cover plate 1025 and the base 1026 can rotate relative to each other, and further the cover plate 1025 and the base 1026 can be overlapped or unfolded with each other. By providing the first rotating shaft 10266 and the second rotating shaft 10254, the cover plate 1025 and the base 1026 can be rotatably connected, which is convenient for opening and closing.

[0123] In some embodiments, such as Figure 16 、 Figure 17As shown, a convex portion 10266a is provided on the first rotating shaft 10266, and a concave portion 10254a matching the convex portion 10266a is provided on the second rotating shaft 10254. When the first rotating shaft 10266 and the second rotating shaft 10254 rotate relative to each other until the convex portion 10266a and the concave portion 10254a are matched, the contact area between the first rotating shaft 10266 and the second rotating shaft 10254 is the largest, so the frictional force between the first rotating shaft 10266 and the second rotating shaft 10254 is the largest, and the cover plate 1025 and the base 1026 are in a hovering state.

[0124] This application does not limit the number of the convex portion 10266a on the first rotating shaft 10266 and the concave portion 10254a on the second rotating shaft 10254, and can make the convex portion 10266a on the first rotating shaft 10266 and the concave portion 10254a on the second rotating shaft 10254 be evenly arranged, and each convex portion 10266a can be matched with any concave portion 10254a. In this way, the cover plate 1025 and the base 1026 can hover at multiple positions.

[0125] In some embodiments, a plurality of convex portions 10266a are provided on the first rotating shaft 10266. In this embodiment, as Figure 16 shown, 6 convex portions 10266a are provided on the first rotating shaft 10266, and the 6 convex portions 10266a are arranged at intervals. The second rotating shaft 10254 is provided with through holes matching the first rotating shaft 10266. The through holes of the second rotating shaft 10254 include: 6 concave portions 10254a, and each convex portion 10266a and the concave portion 10254a are matched. In other embodiments, 1 convex portion 10266a can be provided on the first rotating shaft 10266, and a plurality of concave portions 10254a matching the convex portion 10266a can be provided on the second rotating shaft 10254. This application does not limit the number of the convex portion 10266a and the concave portion 10254a, and these all belong to the protection scope of this application.

[0126] As Figure 16 shown, when the first rotating shaft 10266 and the second rotating shaft 10254 rotate relative to each other until the 6 convex portions 10266a and the 6 concave portions 10254a are matched, the contact area between the first rotating shaft 10266 and the second rotating shaft 10254 is the largest, so the frictional force between the first rotating shaft 10266 and the second rotating shaft 10254 is the largest, and the cover plate 1025 and the base 1026 are in a hovering state. As Figure 17As shown, when the first rotating shaft 10266 and the second rotating shaft 10254 rotate relative to each other until the six convex portions 10266a do not match the six concave portions 10254a (in the intermediate state), the contact area between the first rotating shaft 10266 and the second rotating shaft 10254 is small, so the frictional force between the first rotating shaft 10266 and the second rotating shaft 10254 is small. Since the frictional force between the convex portion 10266a and the concave portion 10254a is increased, the hovering effect of the housing 1021 at any angle can be improved.

[0127] Next, referring to Figure 6 , the connector 1020 further includes: a wiring terminal 1022, and the wiring terminal 1022 is installed on the first positioning portion 10262 and the second positioning portion 10263 of the base 1026 through the positioning holes 1023. The wiring terminal 1022 is used for electrically connecting with the cable terminal 1031 of the cable 103. Among them, the number of the wiring terminals 1022 is multiple.

[0128] Taking the installation of the wiring terminal 1022 on the first positioning portion 10262 and the second positioning portion 10263 as an example, the structures of the wiring terminal 1022, the first positioning portion 10262 and the second positioning portion 10263 will be described.

The openings of the first positioning hole 1023a and the second positioning hole 1023b are located on the end surface of the first positioning portion 10262 facing away from the main body portion 10261. The first positioning hole 1023a and the second positioning hole 1023b extend along the Z-axis direction.

[0134] The second positioning portion 10263 is provided with a third positioning hole 1023c for installing the third terminal 1022c (the second power terminal (R2+)) and a fourth positioning hole 1023d for installing the fourth terminal 1022d (the second grounding terminal (R2-)). The openings of the third positioning hole 1023c and the fourth positioning hole 1023d are located on the end surface of the second positioning portion 10263 facing away from the main body portion 10261. The third positioning hole 1023c and the fourth positioning hole 1023d extend along the Z-axis direction.

[0135] Thus, the first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d can be sequentially installed in the base 1026 along the X direction to form two sets of positive and negative electrode circuits.

[0136] The structure of the terminal 1022 is not limited in the embodiment of the present application. In some embodiments, as Figure 18 shown, the terminal 1022 includes a connected fixing portion (the first fixing portion 10222, the second fixing portion 10223) and a connecting portion 10221. The connecting portion 10221 is connected to the cable 103, and the fixing portion (the first fixing portion 10222, the second fixing portion 10223) is used to insert into the mounting hole 1024 of the base 1026 so that the terminal 1022 is installed on the base 1026.

[0137] In this embodiment, each terminal 1022 includes a connecting portion 10221 and fixing portions (a first fixing portion 10222 and a second fixing portion 10223) connected to the connecting portion 10221.

Among them, the material of each terminal 1022 is a conductive material. Exemplarily, the material of each terminal 1022 is copper. In other embodiments, the material of each terminal 1022 may also be other conductive materials such as aluminum, and the present application does not make any limitation thereto.

[0138] The following takes the structure of the first terminal 1022a as an example for illustration. Other terminals 1022 may adopt the same or similar structures as the first terminal 1022a, and reference may be made to the description of the first terminal 1022a. Please refer to Figure 18 , Figure 18 is Figure 6 a schematic perspective view of the first terminal 1022a in the connector shown.

[0139] The first terminal 1022a includes a connecting portion 10221 and fixing portions. Specifically, the number of fixing portions is two, namely: a first fixing portion 10222 and a second fixing portion 10223. The first fixing portion 10222 and the second fixing portion 10223 are respectively connected to opposite sides of the connecting portion 10221. The connecting portion 10221 is in the shape of a square block. The connecting portion 10221 is provided with a first connection hole A, and the first connection hole A penetrates the connecting portion 10221 along the Z-axis direction. The first fixing portion 10222 is disposed on the side of the connecting portion 10221 facing the positive Y-axis direction, and the second fixing portion 10223 is disposed on the side of the connecting portion 10221 facing the negative Y-axis direction. The first fixing portion 10222 and the second fixing portion 10223 are spaced apart from each other. Among them, one end of each fixing portion (the first fixing portion 10222 and the second fixing portion 10223) is connected to the connecting portion 10221, and the other end extends along the Z-axis direction.

[0140] In this embodiment, the connecting portion 10221 is a square block, and the two fixing portions (the first fixing portion 10222 and the second fixing portion 10223) are respectively connected to opposite side portions of the connecting portion 10221. The cross-sectional shape of the first terminal 1022a along the YZ plane is generally in the shape of a C.

[0141] In other embodiments, the number of the fixing parts (the first fixing part 10222, the second fixing part 10223) may also be one, three, four, etc. For example, the connecting part 10221 may be connected to one or more fixing parts (the first fixing part 10222, the second fixing part 10223).

[0142] The embodiments of the present application do not limit the sizes of the first fixing part 10222 and the second fixing part 10223. In some embodiments, the length of the first fixing part 10222 may be made smaller than the length of the second fixing part 10223.

[0143] In addition, to make it easier for the fixing parts (the first fixing part 10222, the second fixing part 10223) to extend into the positioning holes, in some embodiments, the end faces of the first fixing part 10222 and / or the second fixing part 10223 away from the connecting part 10221 are arc-shaped surfaces. In this way, compared with the square end, the guiding performance of the arc-shaped surface is better, and it can make it more convenient for the terminal 1022 to be inserted into the positioning hole of the base 1026.

[0144] In some embodiments, a clamping groove is further provided on the fixing part, so that the clamping grooves of every two adjacent terminals 1022 can be clamped by a clamping pin. Thereby, two adjacent terminals can be relatively fixed, avoiding relative movement between adjacent positive and negative terminals, and improving the stability of electrical connection. At the same time, by connecting two adjacent terminals with a clamping pin, it can be avoided that two adjacent terminals are disengaged from the positioning holes of the base.

[0145] For example, as Figure 19 shown, the first fixing part 10222 of the first terminal 1022a and the first fixing part 10222 of the second terminal 1022b are adjacent. To improve the connection stability between the first terminal 1022a and the second terminal 1022b and the base 1026, the connector 1020 further includes: a first clamping pin 1028. A first clamping groove 10224a can be provided on the first fixing part 10222 of the first terminal 1022a, and a second clamping groove 10224b can be provided on the first fixing part 10222 of the second terminal 1022b, so that the first clamping pin 1028 can be clamped with the first clamping groove 10224a and the second clamping groove 10224b.

[0146] In this way, the first fixing part 10222 of the first terminal 1022a and the first fixing part 10222 of the second terminal 1022b can be relatively fixed, avoiding relative movement between adjacent positive and negative terminals 1022, and improving the stability of electrical connection. At the same time, by connecting two adjacent terminals 1022 with a clamping pin, it can be avoided that the first terminal 1022a and the second terminal 1022b are disengaged from the positioning holes of the base 1026.

[0147] Correspondingly, the first fixing portions 10222 of the third terminal 1022c and the fourth terminal 1022d are adjacent. To improve the connection stability between the third terminal 1022c and the fourth terminal 1022d and the base 1026, the connector 1020 further includes: a second clamping pin (having the same or similar structure as the first clamping pin, not shown in the figure). A third slot can be provided on the first fixing portion 10222 of the third terminal 1022c, and a fourth slot can be provided on the first fixing portion 10222 of the fourth terminal 1022d, so that the second clamping pin can be clamped with the third slot and the fourth slot.

[0148] In this way, the first fixing portions 10222 of the third terminal 1022c and the fourth terminal 1022d can be relatively fixed, avoiding relative movement between adjacent positive and negative terminals 1022, and improving the stability of electrical connection. At the same time, by connecting adjacent two terminals 1022 with the second clamping pin, it can be avoided that the third terminal 1022c and the fourth terminal 1022d are disengaged from the mounting holes 1024 of the base 1026.

[0149] The number of slots on the fixing portion in the embodiments of the present application is not limited. In some embodiments, for the terminals arranged at the edge positions, slots can be provided only on one side of the fixing portion close to the adjacent terminal. For the terminals arranged at the middle positions, slots can be provided on both sides of the fixing portion, so that the fixing portion forms a hammer shape. These all belong to the protection scope of the present application.

[0150] Next, in conjunction with Figure 6 、 Figure 8 the connection manner between the terminal 1022 and the cable terminal 1031 will be described. Please refer to Figure 8 , the cable 103 is electrically connected to the power interface module 102 through the connection between the cable terminal 1031 and the terminal 1022.

[0151] In this embodiment, as Figure 8 shown, the cable 103 includes: a first cable 103a, a second cable 103b, a third cable 103c, and a fourth cable 103d. Among them, the first cable 103a is connected to the first cable terminal 1031a as Figure 6 shown, the second cable 103b is connected to the second cable terminal 1031b as Figure 6 shown, the third cable 103c is connected to the third cable terminal 1031c as Figure 6 shown, and the fourth cable 103d is connected to the fourth cable terminal 1031d as Figure 6 shown.

[0152] That is, the first cable terminal 1031a is used for electrically connecting to the first terminal 1022a (the first power terminal (R1+)). The second cable terminal 1031b is used for electrically connecting to the second terminal 1022b. The third cable terminal 1031c is used for electrically connecting to the third terminal 1022c (the second power terminal (R2+)) and the third terminal 1022c. The fourth cable terminal 1031d is used for electrically connecting to the fourth terminal 1022d (the second ground terminal (R2−)).

[0153] Among them, the material of the cable terminal 1031 of each cable 103 is a conductive material. Exemplarily, the material of the cable terminal 1031 of each cable 103 is copper. When the cable terminal 1031 of the cable 103 contacts the terminal 1022, current can flow between them, that is, current can be transmitted between them. In other embodiments, the material of the cable terminal 1031 of each cable 103 can also be other conductive materials such as aluminum, and the present application does not make any limitation in this regard.

[0154] During operation, the alternating current output by the external power supply can be fed to the power interface module 102 through the first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d along the first cable 103a, the second cable 103b, the third cable 103c, and the fourth cable 103d respectively. After being rectified by the power interface module 102, it is converted into direct current and fed to the device body 101 to realize the rectification function of the connector 1020.

[0155] To connect the cable terminal 1031 and the terminal 1022, in some embodiments, the connector 1020 further includes a connecting member 1029. The connecting member 1029 is used to realize the connection between the terminal 1022 and the cable terminal 1031 to ensure stable contact between the terminal 1022 and the cable terminal 1031. Among them, the number of the connecting members 1029 is multiple, and each terminal 1022 is connected to the cable terminal 1031 of a cable 103 through a connecting member 1029. In this embodiment, the material of each connecting member 1029 can be a conductive material or an insulating material, and the present application does not make any limitation in this regard.

[0156] In this embodiment, there are four connecting members 1029, namely a first connecting member 1029a, a second connecting member 1029b, a third connecting member 1029c, and a fourth connecting member 1029d. The first connecting member 1029a is used to connect the first cable terminal 1031a of the first cable 103a and the first terminal 1022a. The second connecting member 1029b is used to connect the second cable terminal 1031b of the second cable 103b and the second terminal 1022b. The third connecting member 1029c is used to connect the third cable terminal 1031c of the third cable 103c and the third terminal 1022c. The fourth connecting member 1029d is used to connect the fourth cable terminal 1031d of the fourth cable 103d and the fourth terminal 1022d.

[0157] It should be noted that in this embodiment, the first connecting member 1029a, the second connecting member 1029b, the third connecting member 1029c, and the fourth connecting member 1029d have similar structures. The third cable 103c, the fourth cable 103d, the first cable 103a, and the second cable 103b have similar structures. The first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d have similar structures. To avoid repetition, only the connection between the first terminal 1022a and the first cable terminal 1031a of the first cable 103a through the first connecting member 1029a will be described in detail herein.

[0158] The following takes the connection between the first terminal 1022a and the first cable terminal 1031a of the first cable 103a through the first connecting member 1029a, and further realizes its connection with the first cable 103a as an example for description.

[0159] In this embodiment, the connecting portion 10221 of the first terminal 1022a is provided with a first connection hole A. Along the Z-axis direction, the first connection hole A penetrates through the connecting portion 10221 of the first terminal 1022a. In this embodiment, the connecting portion 10221 of the first terminal 1022a is located between the base 1026 and the cover plate 1025. Among them, the first connection hole A corresponds to the positioning hole 1023.

[0160] The first cable terminal 1031a is provided with a second connection hole B which penetrates the first cable terminal 1031a in the Z-axis direction. In this embodiment, the first cable terminal 1031a is located between the base 1026 and the first terminal 1022a. Among them, the second connection hole B corresponds to the first connection hole A and the positioning hole 1023. The first connector 1029a passes through the first connection hole A of the connection part 10221 of the terminal 1022 and the second connection hole B of the first cable terminal 1031a, so that the first cable terminal 1031a is electrically connected to the connection part 10221 of the terminal 1022.

[0161] For example, the first connector 1029a sequentially passes through the first connection hole A of the connection part 10221 of the terminal 1022 and the second connection hole B of the first cable terminal 1031a in the Z-axis direction, extends into the positioning hole 1023 of the first positioning part 10262, and is screwed with the positioning hole 1023, so that the first cable terminal 1031a is clamped between the connection part 10221 and the connector 1029 installed on the first positioning part 10262.

[0162] Thus, the first cable terminal 1031a is connected to the connection part 10221 of the terminal 1022 through the first connector 1029a, so that the first cable terminal 1031a and the connection part 10221 of the terminal 1022 are stably in contact, and then stable current flow is realized, that is, the first cable terminal 1031a is stably electrically connected to the connection part 10221 through the first connector 1029a.

[0163] The embodiment of the present application does not limit the connection method between the connector 1029 and the base 1026. In some embodiments, the connector 1029 and the base 1026 can be detachably connected together by a threaded connection method.

[0164] For example, the connector 1029 includes a first limiting part and a first screwing part. The first screwing part is located on the side of the first limiting part facing the negative Z-axis direction and is fixedly connected to the first limiting part. In the Y-axis direction, the width dimension of the first limiting part is greater than the width dimension of the first screwing part. Among them, the outer peripheral surface of the first screwing part is provided with threads.

[0165] In some embodiments, as Figure 20 shown, the connector 1020 further includes: a nut 10260 which is embedded in the positioning hole 1023. The connector 1029 can be a bolt. The connector 1029 is provided with an external thread, and the connector 1029 can be threadedly connected to the nut 10260.

[0166] In this way, by arranging the nut 10260 in the positioning hole 1023, the nut 10260 is clamped in the positioning hole 1023, eliminating the need to provide threads on the inner side of the positioning hole 1023 and reducing the process difficulty.

[0167] The embodiments of the present application do not limit the connection manner between the nut 10260 and the positioning hole 1023. In some embodiments, as Figure 20 shown, the nut 10260 is clamped with the positioning hole 1023. For example, the outer shape of the nut 10260 matches the shape of the positioning hole 1023, and the cross-sectional shape of the positioning hole 1023 is polygonal or irregular. For example, the cross-section of the positioning hole 1023 can be cruciform, quadrilateral, pentagonal, hexagonal, etc. In this way, the nut 10260 can be prevented from rotating relative to the positioning hole 1023, ensuring stable contact between the first cable terminal 1031a and the connecting portion 10221, avoiding shaking between the two, and enabling stable current flow between the first cable terminal 1031a and the first wiring terminal 1022a, that is, realizing stable electrical connection between the first cable terminal 1031a and the first wiring terminal 1022a.

[0168] The first cable terminal 1031a is inserted and installed in the connecting portion 10221 of the connector 1029 and the wiring terminal 1022. The first screwing portion sequentially passes through the second connection hole B, the first connection hole A along the Z-axis direction, and extends into the positioning hole 1023, and is screwed with the nut 10260 through the cooperation of the threads provided on the outer surface of the first screwing portion and the threads provided on the inner wall of the hole of the nut 10260. Rotate the first limiting portion along the thread direction of the first screwing portion, and the first limiting portion moves along the Z-axis direction towards the direction close to the base 1026 along with the first screwing portion, and abuts against the first cable terminal 1031a.

[0169] At this time, the first cable terminal 1031a is clamped between the connecting portion 10221 of the connector 1029 and the wiring terminal 1022, ensuring stable contact between the first cable terminal 1031a and the connecting portion 10221, avoiding shaking between the two, and enabling stable current flow between the first cable terminal 1031a and the first wiring terminal 1022a, that is, realizing stable electrical connection between the first cable terminal 1031a and the first wiring terminal 1022a. Moreover, since the width dimension of the first limiting portion is greater than the width dimension of the first screwing portion in the Y-axis direction, the first limiting portion can play a limiting role, facilitating the assembly between the first connector 1029a and the connector 1029. By the abutment of the first limiting portion and the connecting portion 10221, it is beneficial to ensure stable contact between the first cable terminal 1031a and the connecting portion 10221, with low processing precision requirements and low processing costs.

[0170] In the connector provided by the embodiment of the present application, the first connecting member 1029a sequentially passes through the first cable terminal 1031a and the connecting portion 10221 of the wiring terminal 1022 along the Z-axis direction, and is screwed with the nut 10260 in the positioning hole. The first limiting portion of the first connecting member 1029a abuts against the first cable terminal 1031a, ensuring stable contact between the first cable terminal 1031a and the connecting portion 10221 of the wiring terminal 1022, thereby realizing stable current conduction. The first wiring terminal 1022a and the first cable terminal 1031a can be quickly connected through the first connecting member 1029a, reducing the assembly difficulty, shortening the assembly time, having a simple structure, being easy to process, and saving costs.

[0171] In the above embodiment, the fixing portions (the first fixing portion 10222 and the second fixing portion 10223) of the wiring terminal 1022 are installed in the base 1026. Specifically, the fixing portions (the first fixing portion 10222 and the second fixing portion 10223) of the wiring terminal 1022 can be passed through the gap 10230 between the positioning hole 1023 and the nut 10260.

[0172] For example, Figure 20 As shown, the cross-section of the positioning hole 1023 is in a "cross" shape, and the nut 10260 is square, including: a first side, a second side, a third side, and a fourth side. The first side and the second side are arranged opposite to each other along the X direction, and the third side and the fourth side are arranged opposite to each other along the Y direction. When the nut 10260 is arranged in the positioning hole 1023, the first side and the second side are closely attached to the inner wall of the positioning hole 1023, and a gap 10230 is provided between the third side and the fourth side and the inner side wall of the positioning hole 1023. The fixing portions (the first fixing portion 10222 and the second fixing portion 10223) of the wiring terminal 1022 are passed through the gap 10230 between the third side and the fourth side and the inner side wall of the positioning hole 1023.

[0173] In order to improve the electrical connection stability of the wiring terminal 1022, in some embodiments, such as Figure 21 As shown, the fixing portions (the first fixing portion 10222 and the second fixing portion 10223) of the wiring terminal 1022 are provided with buckles 10220 for clamping with the outer side wall of the nut 10260.

[0174] The embodiments of the present application do not limit the structure of the buckle 10220. For example, the buckle 10220 protrudes from the fixing part (the first fixing part 10222 and the second fixing part 10223), and the buckle 10220 can adopt an elastic structure. The shape of the buckle 10220 in this embodiment is not limited and can be circular, square, etc. The buckle 10220 is arranged on the inner wall of the fixing part (the first fixing part 10222 and the second fixing part 10223) of the terminal 1022. When the terminal 1022 is installed on the base 1026, the inner wall of the fixing part (the first fixing part 10222 and the second fixing part 10223) faces the outer wall of the nut 10260.

[0175] In some embodiments, a recess 10254 matching the buckle 10220 can also be arranged on the outer wall of the nut 10260, so that the buckle 10220 is snap-fitted with the recess 10254, improving the stability of the electrical connection.

[0176] The above embodiments are described by taking the connector including 4 terminals as an example. In other embodiments, as Figure 22 shown, the connector can include 2 terminals, and its structure can refer to the above embodiments and will not be elaborated here.

[0177] In other embodiments, as Figure 23 shown, the connector includes 6 terminals: the first terminal 1022a, the second terminal 1022b, the third terminal 1022c, the fourth terminal 1022d, the fifth terminal 1022e, and the sixth terminal 1022f. The difference from the above embodiments is that the terminals 1022 are divided into two rows along the Y direction. The first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d are arranged in the first row along the X direction, and the fifth terminal 1022e and the sixth terminal 1022f are arranged in the second row along the X direction.

[0178] Among them, the first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d can adopt the same structure as Figure 18 shown. The fixing parts ((10222 and 10223)) of the first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d can be arranged at intervals on the opposite sides of the connecting part 10221 along the Y direction, and the fixing parts (10222 and 10223) of the fifth terminal 1022e and the sixth terminal 1022f can be arranged at intervals on the opposite sides of the connecting part 10221 along the X direction. All of these belong to the protection scope of the present application.

[0179] In some embodiments, a corner may also be formed at the end of the terminal block 1022 (the end of the fixing portion away from the connecting portion). The direction of the corner is not limited in the embodiments of the present application and can be adjusted according to the wiring inside the device body, which will not be elaborated herein. These all fall within the protection scope of the present application.

[0180] Correspondingly, the connector further includes: a first positioning hole 1023a for installing the first terminal block 1022a, a second positioning hole 1023b for installing the second terminal block 1022b, a third positioning hole 1023c for installing the third terminal block 1022c, a fourth positioning hole 1023d for installing the fourth terminal block 1022d, a fifth positioning hole 1023e for installing the fifth terminal block 1022e, and a sixth positioning hole 1023f for installing the sixth terminal block 1022f.

[0181] Correspondingly, as Figure 24 shown, the connector further includes: a first mounting hole 1024a communicating with the first positioning hole 1023a, a second mounting hole 1024b communicating with the second positioning hole 1023b, a third mounting hole 1024c communicating with the third positioning hole 1023c, a fourth mounting hole 1024d communicating with the fourth positioning hole 1023d, a fifth mounting hole 1024e communicating with the fifth positioning hole 1023e, and a sixth mounting hole 1024f communicating with the sixth positioning hole 1023f.

[0182] The first mounting hole 1024a, the second mounting hole 1024b, the third mounting hole 1024c, the fourth mounting hole 1024d, the fifth mounting hole 1024e, and the sixth mounting hole 1024f are all used for installing cables. The first mounting hole 1024a, the second mounting hole 1024b, the third mounting hole 1024c, and the fourth mounting hole 1024d are located in the first row, and the fifth mounting hole 1024e and the sixth mounting hole 1024f are located in the second row.

[0183] Among them, in order to avoid interference between the cables connected to the terminal blocks in the first row and the cables connected to the terminal blocks in the second row, the height of the mounting holes can be adjusted so that the mounting hole heights of the cables in the first row and the mounting hole heights of the cables in the second row are different. In this way, the cable terminals can be staggered in the Z direction to avoid interference.

[0184] Exemplarily, as Figure 24 shown, the base 1026 can be divided into two parts: a first base and a second base. The bottom surfaces of the first base and the second base are flush, and the height of the first base is greater than the height of the second base. Among them, the first positioning hole 1023a, the second positioning hole 1023b, the third positioning hole 1023c, and the fourth positioning hole 1023d are formed on the first base, and the fifth positioning hole 1023e and the sixth positioning hole 1023f are formed on the second base.

[0185] The first row of terminals 1022: the first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d are installed in the positioning holes 1023 of the first base, and the second row of terminals: the fifth terminal 1022e and the sixth terminal 1022f are installed in the positioning holes 1023 of the second base.

[0186] In this way, the first row of mounting holes 1024: the first mounting hole 1024a, the second mounting hole 1024b, the third mounting hole 1024c, and the fourth mounting hole 1024d are formed on the first base, and the second row of mounting holes 1024: the fifth mounting hole 1024e and the sixth mounting hole 1024f are formed on the second base, so that a height difference is formed between the mounting holes in the second row and the mounting holes in the first row, thereby avoiding interference between the cables installed in the mounting holes in the first row and the cables installed in the mounting holes in the second row.

[0187] The embodiment of the present application provides a connector, including: a housing, a plurality of wiring terminals and a plurality of connectors, the housing is provided with a plurality of positioning holes, the wiring terminals are installed in the positioning holes. The housing is also provided with a mounting hole connected to the plurality of positioning holes, the plurality of mounting holes are used to install cables, the wiring terminals are provided with a first connection hole corresponding to the positioning holes, the cable includes: a cable terminal, the cable terminal is provided with a second connection hole corresponding to the positioning hole. The connector is inserted through the first connection hole, the second connection hole and the positioning hole, so that the cable terminal is electrically connected to the wiring terminal. Wherein, each of the mounting holes includes: at least two interconnected sub-mounting holes. Thus, the plurality of sub-mounting holes can be used to install cables. When a plurality of connectors are arranged on a network device, a connector with a corresponding outlet direction (mounting hole opening direction) can be selected according to the installation position. Therefore, the connector with a plurality of sub-mounting holes can be used in a plurality of different positions. Compared with the mounting hole with only one direction in the related art, there is no need to rotate the connector when installing the connector at different positions, which reduces the risk of wrong connection and reduces the potential safety hazard. In addition, there is no need to design an adapter for transfer inside the network device, which reduces the cost and improves the power supply reliability.

[0188] In some embodiments of the present application, each mounting hole includes two sub-mounting holes, and the angle between the two sub-mounting holes is 180°. Thus, two connectors of this structure can be set on opposite sides of the network device. After installation, the positive and negative power sources of the two connectors correspond to each other, and there is no risk of wrong connection, which reduces safety hazards. In addition, there is no need to design adapters for switching inside the network device, which reduces costs and improves power supply reliability.

[0189] As described above, it is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claimed rights.
