Abstract

Embodiments of the present application provide a connector and a network device. The connector comprises a housing, a plurality of wiring terminals, and a plurality of connecting members; a plurality of positioning holes are formed in the housing; the wiring terminals are mounted on the positioning holes; mounting holes communicated with the plurality of positioning holes are further formed in the housing; the plurality of mounting holes are used for mounting cables; and each mounting hole comprises a first sub-mounting hole and a second sub-mounting hole which are communicated with each other. Therefore, when connectors are mounted at different positions of one network device, the connectors with the corresponding cable outlet directions (the opening directions of mounting holes) can be selected, and the connectors provided with a plurality of sub-mounting holes can be used at a plurality of different positions. Compared with the mounting holes in only one direction in the prior art, the connectors do not need to be rotated when being mounted at different positions, so that the risk of incorrect connection is reduced, and the potential safety hazard is reduced; moreover, an adapter does not need to be designed in the network device for adapting, so that the cost is reduced.

Description

Connectors and network equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 29, 2023, with application number 202311866371.3 and application name “Connectors and Network Devices,” the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of power supply devices, and in particular to a connector and a network device. Background Art

[0003] Currently, 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 power cable from the customer's room is connected to the network equipment from one side.

[0004] As equipment evolves, higher power distribution is required. Single-circuit 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 achieved by placing two single-circuit power supplies on both sides of the network equipment.

[0005] 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.

[0006] However, the connector outlet direction of a 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 power supplies on both sides are opposite, which poses a risk of incorrect connection and a safety hazard. In addition, adapters need to be designed inside the network equipment for connection, which is costly. Multiple connection attempts will reduce power supply reliability and increase costs.

[0007] Summary of the Invention

[0008] 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.

[0009] To achieve the above objectives, the present invention adopts the following technical solutions:

[0010] In a first aspect of an 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 being mounted in the positioning holes; the housing is further provided with mounting holes communicating with the plurality of positioning holes, the plurality of mounting holes being used to mount cables; the wiring terminal is provided with a first connection hole corresponding to the positioning hole, the cable comprising: a cable terminal, the cable terminal being provided with a second connection hole corresponding to the positioning hole; the connector is passed through the first connection hole, the second connection hole, and the positioning hole to electrically connect the cable terminal to the wiring terminal; each mounting hole comprises: at least two interconnected sub-mounting holes. Thus, the plurality of sub-mounting holes can be used to mount cables. When multiple connectors are provided on a network device, a connector with a corresponding outlet direction (mounting hole opening direction) can be selected according to the installation position. Therefore, a connector with multiple sub-mounting holes can be used in multiple different positions. Compared with the related art having a mounting hole with only one direction, there is no need to rotate the connector when installing the connector in different positions, thereby reducing the risk of misconnection and reducing safety hazards. In addition, no adapter is required to be designed for connection within the network device, thereby reducing costs and improving power supply reliability.

[0011] In one optional implementation, each mounting hole includes two sub-mounting holes, with the angle between the two sub-mounting holes being 180°. This allows two connectors of this structure to be placed on opposite sides of a network device. Once installed, the positive and negative power lines of the two connectors align, eliminating the risk of misconnection and reducing safety hazards. Furthermore, no adapters are required within the network device for connection, reducing costs and improving power supply reliability.

[0012] In an optional implementation, the mounting hole and the positioning hole are perpendicular to each other. Thus, the mounting hole and the positioning hole can be arranged in a T-shape, avoiding interference between the cable disposed in the mounting hole and the terminal disposed in the positioning hole in a non-connected position, and making full use of the space of the connector.

[0013] In one optional implementation, the housing includes: a connected cover plate and a base, the plurality of positioning holes being provided on the base, and a plurality of retaining walls being provided on a surface of the base adjacent to the cover plate. The base, the plurality of retaining walls, and the cover plate enclose the plurality of mounting holes. Thus, the orientation of the mounting holes can be adjusted by adjusting the angle of the retaining walls, resulting in a simple process and ease of production.

[0014] In one optional implementation, the connector further includes: a first rotating shaft and a second rotating shaft arranged coaxially, the base being connected to the first rotating shaft, the cover being connected to the second rotating shaft, the first rotating shaft being sleeved on the second rotating shaft, and the first and second rotating shafts being rotatably connected. Thus, when the first and second rotating shafts rotate relative to each other, the cover can open and close relative to the base, facilitating installation of cables and terminal blocks.

[0015] In an optional implementation, the first rotating shaft is provided with a plurality of protrusions, and the second rotating shaft is provided with concave portions that match the protrusions. Thus, when the first rotating shaft and the second rotating shaft rotate relative to each other until the protrusions and the concave portions match, the contact area between the first rotating shaft and the second rotating shaft is maximized, the friction between the first rotating shaft and the second rotating shaft is maximized, and the cover 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 protrusions do not match the concave portions (in an intermediate state), the contact area between the first rotating shaft and the second rotating shaft is smaller, and the friction between the first rotating shaft and the second rotating shaft is smaller. Since the friction between the protrusions and the concave portions is increased, the hovering effect of the shell at any angle can be improved.

[0016] In an optional implementation, the connector further includes a fixing member, the cover includes a first assembly portion, the base includes a second assembly portion, the fixing member includes a first portion, a second portion, and a third portion, the third portion being disposed between the first and second portions, the second portion being threaded, and in an unlocked state, the third portion being movable relative to the first assembly portion in an axial direction of the first assembly portion; in a locked state, the second portion being able to extend beyond the first assembly portion for engagement with the second assembly portion. Thus, the fixing member can detachably connect the upper cover and the base.

[0017] In an optional implementation, a groove is provided on the surface of the upper cover, and the first portion is disposed in the groove, thereby preventing the fixing portion from protruding from the surface of the upper cover and improving the flatness of the upper cover.

[0018] In one optional implementation, a through-hole is provided at the bottom of the groove, through which the third portion is inserted. The diameter of the through-hole is smaller than the outer diameter of the second portion, and the diameter of the through-hole is smaller than the outer diameter of the first portion. Thus, the fixing portion utilizes a captive screw. When unlocked, the fixing member can move within the first assembly portion but will not fall out of the through-hole, thereby improving the connection reliability of the fixing member.

[0019] In one optional implementation, the groove is elongated, with its length parallel to the axis of the mounting hole. Thus, the elongated groove design, for example, can adopt a waist-shaped groove (also known as a runway-shaped groove), which is elongated in the middle and curved at both ends. This groove structure saves space perpendicular to the mounting hole, achieving a high-density design for the overall structure.

[0020] In an optional implementation, each two adjacent grooves are connected by a reinforcing rib. Thus, by providing reinforcing ribs between adjacent grooves, the strength of the upper cover can be improved.

[0021] In one optional implementation, the connector further includes a nut embedded in the positioning hole, and the connector is threadedly connected to the nut. Thus, the connector can be a bolt having external threads, which can be threadedly connected to the nut. Thus, by placing the nut in the positioning hole, the nut is locked into the positioning hole, eliminating the need for threads inside the positioning hole, thereby reducing the process difficulty.

[0022] In one optional implementation, the nut's shape matches the positioning hole's, and the positioning hole's cross-section is polygonal or irregular. This prevents the nut from rotating relative to the positioning hole, ensuring stable contact between the cable terminal and the connecting portion, preventing any shaking between the two, and achieving stable current flow between the cable terminal and the wiring terminal, i.e., a stable electrical connection between the cable terminal and the wiring terminal.

[0023] In one optional implementation, the terminal block includes a fixed portion and a connecting portion, the connecting portion being provided with the first connecting hole, and the fixed portion being inserted into the gap between the positioning hole and the nut. Thus, the connecting portion is connected to the cable, and the fixed portion is inserted into the mounting hole of the base, so that the terminal block is mounted on the base, thereby connecting the cable to the terminal block.

[0024] In an optional implementation, the fixing portion includes: a first fixing portion and a second fixing portion, the first fixing portion and the second fixing portion being disposed on opposite sides of the connecting portion. Thus, the cross-section of the terminal block is substantially C-shaped, and the connection to the base is more stable.

[0025] In an optional implementation, the fixing portion is provided with a buckle for engaging with the outer wall of the nut, thereby making the connection between the fixing portion and the nut more stable, preventing the nut and the fixing portion from shaking relative to each other, and improving the stability of the electrical connection.

[0026] In one optional implementation, the fixing portion is provided with a slot, and the slots of each pair of adjacent terminals are connected by a snap-in pin. This allows the adjacent terminals to be relatively fixed, preventing relative movement of the adjacent positive and negative terminals, and improving the stability of the electrical connection. Furthermore, connecting the two adjacent terminals via the snap-in pin prevents them from falling out of the positioning holes of the base.

[0027] In an optional implementation, the end surface of the fixing portion away from the connecting portion is an arc-shaped surface. As a result, the arc-shaped end has better guiding performance than the square end, making it easier to insert the terminal into the positioning hole of the base.

[0028] In an optional 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. This can prevent the cables in the first mounting hole and the second mounting hole from interfering with each other.

[0029] The second aspect of the embodiment of the present application provides a network device, comprising: a cable, a device body, and a connector as described above, wherein the cable is connected to the main device via the connector. Thus, the network device adopts the above connector. When multiple connectors are set on a network device, the corresponding connector can be selected according to the installation position. When the connector is installed at different positions, a connector with a corresponding cable outlet direction (mounting hole opening direction) can be selected. The connector with multiple sub-mounting holes can be used in multiple 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 safety hazards. In addition, there is no need to design an adapter for connection inside the network device, which reduces costs and improves power supply reliability.

[0030] In an optional implementation, the main device further includes: a power interface module, the power interface module being connected to the main device, and the connection terminals of the connector being connected to the power interface module. Thus, the source interface module can be a rectifier that can convert input AC power into output DC power.

[0031] In one optional implementation, the device body is provided with two connectors, one of which connects to the cable via a first sub-mounting hole, and the other connects to the cable via a second sub-mounting hole. Thus, the surface of the connector of the present application is provided with at least two groups of mounting holes. When multiple connectors are symmetrically mounted to the device body, dual-side cable outlets can be achieved without adjusting the connector orientation. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0057] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0058] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0059] The present application provides a network device, which can be a core network, an industrial router, a transmission network, an access network, a data center, etc.

[0060] Figure 1 is a schematic diagram of the structure of a network device provided in this application. As shown in Figure 1, the network device 10 includes: a device body 101, and a power interface unit (PIU) 102 disposed on the device body 101. The power interface unit 102 is used to provide a power interface to connect an external power source to the network device 10.

[0061] In some embodiments, the power interface module 102 may be a rectifier that converts input AC power into output DC power. For example, the power interface module 102 may convert 220V AC power from an external power source into 48V DC power, and output it to the device body 101 for operation of the device body 101. This application does not impose any limitations on the external power source and the device body 101. The external power source may be any device or component capable of outputting AC power, and the device body 101 may be any device or component utilizing DC power.

[0062] The external power supply supplies power to the network device 10 through the cable 103, and the cable 103 is difficult to be directly connected to the network device 10. In some embodiments, the network device 10 may further include: a connector 1020, which is used to connect the cable 103 and the internal circuit.

[0063] FIG3 is a schematic diagram of the structure of a connector. As shown in FIG3 , the connector 1020 includes a housing 1021 and a plurality of connection terminals 1022 . The housing 1021 is used to fix the plurality of connection terminals 1022 .

[0064] The connection terminal 1022 is used to connect the cable 103 and the power interface module 102 , and a plurality of connection terminals 1022 are arranged along the X direction.

[0065] The embodiments of the present application do not limit the material of the housing 1021. In some embodiments, the housing 1021 may be made of insulating materials such as plastics and ceramics.

[0066] The embodiments of the present application do not limit the material of the wiring terminal 1022. In some embodiments, the wiring terminal 1022 may be made of conductive materials such as metals.

[0067] The embodiments of the present application do not limit the number of the wiring terminals 1022 in the connector. In some embodiments, as shown in FIG. 3, there are 4 wiring terminals 1022, 4 mounting holes 1024 and 4 positioning holes 1023. The wiring terminals 1022 include: 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 wiring terminal 1022, the cable 103 and the wiring terminal 1022 can be made to correspond one by one.

[0068] In some embodiments, there are multiple positioning holes 1023 (through holes for mounting the wiring terminals) on the housing 1021, and multiple wiring terminals 1022 are all arranged in the multiple positioning holes 1023. The axial direction of the positioning holes 1023 is parallel to the Z direction.

[0069] The housing 1021 also has multiple mounting holes 1024 communicating with the multiple positioning holes 1023. The multiple mounting holes 1024 are used for mounting the cable 103, and the axial direction of the mounting holes 1024 is parallel to the Y direction.

[0070] In the embodiments of the present application, the Z direction may be the thickness direction of the connector 1020, the X direction may be the length direction of the connector 1020, and the Y direction may 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 may 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 may be greater than, equal to or less than the width. The width direction, length direction and thickness direction of the connector 1020 may also be the width direction, length direction and thickness direction of the connector 1020.

[0071] In some embodiments, as shown in FIG. 4, 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.

[0072] The embodiments of the present application do not limit the number of connectors 1020. In some embodiments, referring to FIG1 , there is one external power supply and four cables 103. The external power supply feeds AC power to the power interface module 102 through the four cables 103. There is one connector 1020, and the connector 1020 feeds the output DC power to the device body 101 through four terminal blocks 1022. It should be noted that since DC power has a direction, the four cables 103 need to be connected to the positive and negative poles of the power interface module 102, respectively. Therefore, only one connector 1020 is required to connect the cables 103 and the power interface module 102 to power the network device 10.

[0073] In other embodiments, as shown in FIG2 , there are eight cables 103 , two or more power interface modules 102 are provided on the network device 10 to power the network device 10 , and two connectors 1020 are provided. Each connector 1020 feeds the output DC power to the device body 101 via four wiring terminals 1022 , thereby providing higher power distribution. For example, the network device 10 is provided with two power interface modules 102 . Considering the wiring space and layout cost, the power interface modules 102 can be placed on both sides of the device body. Accordingly, the connectors 1020 are provided on both sides of the device body, for example, on the left and right sides or on the top and bottom sides of the device.

[0074] When two connectors 1020 are provided on the device body, the wires need to be led out from both sides. Thus, when the same two connectors 1020 are used on the device body, the two connectors 1020 are arranged in a centrally symmetrical manner.

[0075] As shown in Figure 2, the device body is equipped with two connectors 1020: 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 power terminals of the first and second connectors 1020a and 1020b are opposite, posing a risk of misconnection and a safety hazard. Furthermore, the network device 10 requires an adapter for connection, which is costly. Multiple connections also reduce power supply reliability and increase costs.

[0076] To this end, the present application provides an improved connector 1020, the surface of which is provided with at least two groups of symmetrically arranged mounting holes 1024. When multiple connectors 1020 are symmetrically installed to the device body, double-sided wiring can be achieved without adjusting the orientation of the connector 1020.

[0077] Figure 5 is a schematic diagram of the structure of a connector provided in an embodiment of the present application. Figure 6 is a schematic diagram of the disassembled structure of a connector provided in an embodiment of the present application. As shown in Figures 5 and 6, the connector 1020 includes: a housing 1021 and a plurality of connection terminals 1022.

[0078] The housing 1021 is provided with a plurality of positioning holes 1023 for fixing the plurality of connection terminals 1022 , and the axes of the plurality of positioning holes 1023 are parallel to the z direction.

[0079] The housing 1021 is further provided with mounting holes 1024 communicating with the plurality of positioning holes 1023 . The plurality of mounting holes 1024 are used for mounting the cables 103 .

[0080] In some embodiments, each mounting hole 1024 includes at least two interconnected sub-mounting holes. Thus, each of the multiple sub-mounting holes can be used to install cables. When multiple connectors are installed on a network device, a connector with a corresponding cable outlet direction (mounting hole opening direction) can be selected based on the installation location. Therefore, a connector with multiple sub-mounting holes can be used in multiple different locations. Compared to the related art, which only has mounting holes in one direction, there is no need to rotate the connector when installing it in different locations, reducing the risk of misconnection and minimizing safety hazards. Furthermore, there is no need to design adapters for connection within the network device, which reduces costs and improves power supply reliability.

[0081] The present application does not limit the number of sub-mounting holes. Each mounting hole 1024 includes two sub-mounting holes. For example, as shown in FIG7 , each mounting hole 1024 includes: a first sub-mounting hole 10241 and a second sub-mounting hole 10242 that are connected to each other. The first sub-mounting hole 10241 and the second sub-mounting hole 10242 are both connected to the positioning hole 1023. The angle between the first sub-mounting hole 10241 and the second sub-mounting hole 10242 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. In other words, the first sub-mounting hole 10241 and the second sub-mounting hole 10242 extend in different directions, providing more options for cable outlet directions.

[0082] In some embodiments, as shown in FIG7 , the angle between the first sub-mounting hole 10241 and the second sub-mounting hole 10242 is 180°. The axis M of the first sub-mounting hole 10241 and the second sub-mounting hole 10242 is 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 in a "T"-shaped structure, wherein the positioning hole 1023 is the "|" hole in the "T"-shaped through-hole, and the first sub-mounting hole 10241 and the second sub-mounting hole 10242 are the "-" holes in the "T"-shaped hole. This prevents interference between the cables disposed in the mounting holes and the terminal blocks disposed in the positioning holes when not connected, thereby fully utilizing the space in the connector.

[0083] As shown in FIG5 , the mounting hole 1024 has two openings formed on the surface of the housing 1021, and the positioning hole 1023 has one opening formed 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.

[0084] Therefore, two connectors adopting the above structure can be set 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.

[0085] 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 extension directions of the first sub-mounting hole 10241, the second sub-mounting hole 10242 and the third sub-mounting hole are different, providing more options for wire outlet directions.

[0086] This application does not limit the number and angle of the mounting holes 1024. The number of mounting holes 1024 and the angle between adjacent mounting holes 1024 can be selected according to the shape of the shell 1021, which all fall within the scope of protection of this application.

[0087] For example, referring to FIG8 , the connector 1020 can be used in a network device 10 with left and right power supply. The device body 101 is provided with two connectors 1020: 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 direction of the X-axis. Each of these terminals is connected to the cable 103 via a second sub-mounting hole on the side of the housing along the negative direction of the Y-axis. 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 direction of the X-axis. Each of these terminals is connected to the cable 103 via a first sub-mounting hole on the side of the housing along the negative direction of the Y-axis. The positive and negative poles of the second connector 1020b and the first connector 1020a are arranged in the same order, and the two are arranged axially symmetrically. During installation, the positive and negative power supplies of the left and right connectors 1020 can be aligned one by one, eliminating the risk of incorrect connection and reducing safety hazards. In addition, there is no need to design adapters for connection inside the network device 10, which reduces costs and improves power supply reliability.

[0088] In other embodiments, as shown in FIG9 , the connector 1020 can also be used in a network device 10 with dual-side power supply. The device body 101 is provided with two connectors 1020: 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 direction of the Y axis. The second connector 1020b also 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 direction of the Y axis. The positive and negative poles of the second connector 1020b are arranged in the same order as the first connector 1020a. During installation, the positive and negative poles of the upper and lower connectors 1020 are aligned, eliminating the risk of incorrect connection and reducing safety hazards. Furthermore, no adapter is required within the network device 10 for connection, reducing costs and improving power supply reliability.

[0089] 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. The included 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 and second connectors can be installed on opposite sides of the network device 10. After installation, the positive and negative power supply terminals of the second connector 1020b and the first connector 1020a correspond, eliminating the risk of incorrect connection and reducing safety hazards. Furthermore, no adapter is required within the network device 10 for connection, reducing costs and improving power supply reliability.

[0090] Of course, in other embodiments, as shown in FIG10 and FIG11 , the connector 1020 can also be used for a single-side powered network device 10. This application does not impose any limitation on this.

[0091] The embodiment of the present application does not limit the structure of the housing 1021 of the connector 1020. In some embodiments, as shown in Figure 6, the housing 1021 includes two parts: a connected cover 1025 and a base 1026. The structure of the housing 1021 is described below using Figure 6 as an example.

[0092] 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, while the retaining wall 10265 and the first assembly portion 10264 are fixedly connected to the other side of the main body 10261.

[0093] The cover 1025 includes a first surface facing away from the base 1026 and a second surface close to the base 1026. When the cover 1025 is covered on the base 1026, the first surface of the base 1026, the first surface of the cover 1025 and the retaining wall 10265 are arranged to form a plurality of mounting holes 1024.

[0094] 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] In some embodiments, the main body 10261 , the first positioning portion 10262 , the second positioning portion 10263 , the first assembly portion 10264 and the retaining wall 10265 may be integrally formed to simplify the preparation process of the base 1026 and ensure the overall strength of the base 1026 .

[0096] The main body 10261 includes a first surface facing the cover plate 1025 and a second surface opposite the first surface. The retaining wall 10265 and the first assembly portion 10264 are fixedly connected to the first surface of the main body 10261. In this embodiment, the retaining walls 10265 are multiple, spaced apart along the X-direction and protruding from the first surface of the main body 10261 along the Z-direction.

[0097] The Z direction is different from the X direction. In this embodiment, the Z direction and the X direction are perpendicular to each other.

[0098] The first positioning portion 10262 is fixedly connected to the second surface of the main body 10261. The first positioning portion 10262 is protruded from the second surface of the main body 10261 along the negative direction of the Z axis.

[0099] The second positioning portion 10263 is fixedly connected to the second surface of the main body 10261. In this embodiment, the second positioning portion 10263 is located on the side of the first positioning portion 10262 facing the positive direction of the X-axis and is spaced apart from the first positioning portion 10262. The second positioning portion 10263 is protruded from the second surface of the main body 10261 along the negative direction of the Z-axis.

[0100] The first assembly portion 10264 is fixedly connected to the first surface of the main body 10261. In this embodiment, there are two first assembly portions 10264, and the two first assembly portions are spaced apart from each other. Along the Y-axis direction, the above-mentioned retaining wall 10265 is provided between the two first assembly portions 10264. The assembly portion is protruded from the first surface of the main body 10261 along the Z-axis direction. The first assembly portion 10264 is provided with a second fixing hole, and the opening of the first fixing hole is located at the end face of the assembly portion facing away from the main body 10261. The first fixing hole extends along the Z-axis direction. The hole wall of the first fixing hole is provided with a thread.

[0101] The second mounting portion 10251 is fixedly connected to the second surface of the cover plate 1025. In this embodiment, there are two second mounting portions 10251, and the two second mounting portions 10251 are spaced apart from each other. The second mounting portion 10251 is protruded from the second surface of the cover plate 1025 along the Z-axis. The second mounting portion 10251 is provided with a second fixing hole, the opening of which is located on the end surface of the mounting portion facing away from the cover plate 1025. The second fixing hole extends along the Z-axis.

[0102] To enhance the stability of the connection between cover 1025 and base 1026, in some embodiments, connector 1020 further includes a fixing member 1027. FIG12 is a top view of cover 1025. As shown in FIG12, fixing member 1027 is disposed on cover 1025 and can be used to connect cover 1025 to base 1026.

[0103] In this embodiment, referring to FIG. 12 , there are two fixing members 1027 , and the two fixing members 1027 are arranged along the Y-axis direction.

[0104] 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 can be staggered.

[0105] For example, the cable 103 is passed through the mounting hole 1024 along the Y direction, and the fixing members 1027 are arranged in sequence along the Y direction. In other words, multiple fixing members 1027 can be arranged between two adjacent mounting holes 1024. In this way, 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.

[0106] 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 this application.

[0107] During assembly, the fixing member 1027 is passed through the second assembly portion 10251 and the first assembly portion 10264 to connect the cover 1025 and the base 1026. Next, the structure of the fixing member 1027 is described by taking the fixing member 1027 installed on the first assembly portion 10264 and the second assembly portion 10251 as an example.

[0108] Figure 13 is a schematic diagram of the structure of a fixing member provided in an embodiment of the present application. As shown in Figure 13, fixing member 1027 includes a first portion 1027a and a second portion 1027b. Second portion 1027b is located on the side of first portion 1027a facing the negative Z-axis direction and is fixedly connected to first portion 1027a. Along the Y-axis, the width of first portion 1027a is greater than the width of second portion 1027b.

[0109] FIG14 is a cross-sectional view taken along the axis AA in FIG12 . As shown in FIG14 , the second portion 1027 b is configured to connect to the base 1026 . Specifically, the outer surface of the second portion 1027 b is provided with threads. The threads of the second portion 1027 b cooperate with the threads of the first assembly portion 10264 to achieve a threaded connection between the second portion 1027 b and the first assembly portion 10264 . By rotating the first portion 1027 a along the threaded direction of the second portion 1027 b , the first portion 1027 a can move along the Z-axis toward the base 1026 with the second portion 1027 b and abut against the first assembly portion 10264 , thereby stably mounting the fixing member 1027 on the first assembly portion 10264 . In other words, the fixing member 1027 is stably mounted on the base 1026 .

[0110] Because the width of the first portion 1027a is greater than the width of the second portion 1027b along the Y-axis, the first portion 1027a can function as a position limiter, facilitating assembly between the fixing member 1027 and the housing 1021 and improving assembly efficiency. In other embodiments, the width of the first portion 1027a along the Y-axis may be equal to or less than the width of the second portion 1027b, and this is not limited in this application.

[0111] In some embodiments, the fixing member 1027 can be a captive screw.

[0112] In this embodiment, the fixing member 1027 also includes: a third part 1027c, which is arranged between the first part 1027a and the second part 1027b, and the third part 1027c is a non-threaded part, which refers to a 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 unlocked state, the third part 1027c can move relative to the first assembly part 10264 in the axial direction of 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 engagement with the second assembly part 10251.

[0113] For example, 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), wherein 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, and the second assembly 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 assembly portion 10264, so that in the unlocked state, the non-threaded portion can move relative to the first assembly portion 10264 in the axial direction of the first assembly portion 10264. In the locked state, the threaded portion of the screw can extend out of the second assembly portion 10251 for engagement with the first assembly portion 10264, thereby connecting the cover 1025 and the base 1026 together.

[0114] In some embodiments, in order to install the fixing member 1027 , as shown in FIG6 , a plurality of grooves 10252 may be provided on the cover plate 1025 , and the first portion 1027 a (nut) in FIG13 may be provided in the groove 10252 .

[0115] In this way, the nut can be prevented from protruding from the surface of the cover plate 1025, thereby improving the flatness of the surface of the cover plate 1025.

[0116] In some embodiments, as shown in FIG15 , a through hole is provided at the bottom of the groove 10252, and the third portion 1027c (non-threaded portion) is inserted into the through hole. The diameter of the through hole is smaller than the outer diameter of the second portion 1027b (threaded portion), and the diameter of the through hole is smaller than the outer diameter of the first portion 1027a (nut). This prevents the non-threaded portion from passing through the through hole, preventing the fixing member 1027 from dislodging from the through hole when the fixing member 1027 moves axially relative to the first assembly portion 10264 in the unlocked state.

[0117] In order to reduce the space occupied by the groove 10252 in the X direction, the groove 10252 can be designed as a long strip. For example, a waist-shaped groove (also called a runway-shaped groove) as shown in FIG. 15 can be used, which means that the middle is long and the two ends are curved.

[0118] For example, the length direction of the groove 10252 can be parallel to the Y direction. The groove 10252 of this structure can save space and realize a high-density design of the overall structure.

[0119] In some embodiments, in order to increase the strength of the cover plate 1025 , a reinforcing rib 10253 may be provided between two adjacent grooves 10252 , so that every two adjacent grooves 10252 are connected by the reinforcing rib 10253 .

[0120] The reinforcing rib 10253 is fixedly connected to the first surface of the cover plate 1025. In this embodiment, the reinforcing rib 10253 can be a single piece, extending along the X-direction and protruding from the first surface of the cover plate 1025 along the Z-direction. This increases the strength of the cover plate 1025. 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.

[0121] The embodiment of the present application does not limit the connection method between the cover plate 1025 and the base 1026. In the above embodiment, the cover plate 1025 can be connected to the base 1026 via the fixing member 1027. To improve the connection stability between the cover plate 1025 and the base 1026, a rotating shaft can be provided at one end of the cover plate 1025 and the base 1026 to enable the cover plate 1025 and the base 1026 to be rotatably connected.

[0122] Figure 16 is a schematic diagram of the structure of the rotating shaft in Figure 6 when it is in a suspended state. Figure 17 is a schematic diagram of the structure of the rotating shaft in Figure 6 when it is in an intermediate state. As shown in Figures 6 and 16, connector 1020 further includes: a first rotating shaft 10266 and a second rotating shaft 10254 arranged coaxially. Housing 1021 may include a cover 1025, a base 1026, and the first rotating shaft 10266 and the second rotating shaft 10254 connecting the cover 1025 and the base 1026. The base 1026 is connected to the first rotating shaft 10266, and the cover 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. Thus, the cover 1025 and the base 1026 are rotatably coupled via the first rotating shaft 10266 and the second rotating shaft 10254, allowing the cover 1025 and the base 1026 to rotate relative to each other, thereby allowing the cover 1025 and the base 1026 to be folded or unfolded. The provision of the first rotating shaft 10266 and the second rotating shaft 10254 allows the cover 1025 to be rotatably coupled to the base 1026, facilitating opening and closing.

[0123] The housing 1021 may include an open state, a closed state, and an intermediate state between the open state and the closed state. When assembling or repairing the connector 1020, it is necessary to maintain a stable hover in the open state, the closed state, or the intermediate state to facilitate user use of the connector 1020.

[0124] In some embodiments, as shown in Figures 16 and 17 , a convex portion 10266a is provided on the first rotating shaft 10266, and a concave portion 10254a that matches 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 match, the contact area between the first rotating shaft 10266 and the second rotating shaft 10254 is maximized, and the friction force between the first rotating shaft 10266 and the second rotating shaft 10254 is maximized, and the cover 1025 and the base 1026 are in a hovering state.

[0125] The present application does not limit the number of protrusions 10266a on the first rotating shaft 10266 and the recesses 10254a on the second rotating shaft 10254. The protrusions 10266a on the first rotating shaft 10266 and the recesses 10254a on the second rotating shaft 10254 can be evenly arranged, and each protrusion 10266a can match any recess 10254a. In this way, the cover 1025 and the base 1026 can hover in multiple positions.

[0126] In some embodiments, the first rotating shaft 10266 is provided with multiple protrusions 10266a. In this embodiment, as shown in FIG16 , the first rotating shaft 10266 is provided with six protrusions 10266a, which are spaced apart. The second rotating shaft 10254 is provided with a through hole that matches the first rotating shaft 10266. The through hole of the second rotating shaft 10254 includes six recesses 10254a, each of which matches a corresponding protrusion 10266a. In other embodiments, the first rotating shaft 10266 may be provided with one protrusion 10266a, and the second rotating shaft 10254 may be provided with multiple recesses 10254a that match the protrusions 10266a. This application does not limit the number of protrusions 10266a and recesses 10254a, and all such numbers fall within the scope of protection of this application.

[0127] As shown in Figure 16 , when the first rotating shaft 10266 and the second rotating shaft 10254 rotate relative to each other until the six protrusions 10266a mate with the six recesses 10254a, the contact area between the first rotating shaft 10266 and the second rotating shaft 10254 is maximized, and the friction between the first rotating shaft 10266 and the second rotating shaft 10254 is maximized, causing the cover 1025 and the base 1026 to be in a suspended state. As shown in Figure 17 , when the first rotating shaft 10266 and the second rotating shaft 10254 rotate relative to each other until the six protrusions 10266a no longer mate with the six recesses 10254a (in an intermediate state), the contact area between the first rotating shaft 10266 and the second rotating shaft 10254 is reduced, and the friction between the first rotating shaft 10266 and the second rotating shaft 10254 is reduced. Since the friction between the convex portion 10266a and the concave portion 10254a is increased, the hovering effect of the shell 1021 at any angle can be improved.

[0128] 6 , connector 1020 further includes a connection terminal 1022 , which is mounted on first and second positioning portions 10262 and 10263 of base 1026 via positioning holes 1023 . Connection terminal 1022 is configured to electrically connect to cable terminal 1031 of cable 103 . There are multiple connection terminals 1022 .

[0129] The structures of the connecting terminal 1022 , the first positioning portion 10262 , and the second positioning portion 10263 are described below by taking the example of the connecting terminal 1022 being installed on the first positioning portion 10262 and the second positioning portion 10263 .

[0130] 6 , the first positioning portion 10262 includes a first positioning hole 1023a and a second positioning hole 1023b , and the second positioning portion 10263 includes a third positioning hole 1023c and a fourth positioning hole 1023d . The first positioning hole 1023a , the second positioning hole 1023b , the third positioning hole 1023c and the fourth positioning hole 1023d can all be used to install the terminal block 1022 .

[0131] This application does not limit the number of terminals in the connector. It can be 2, 4, 6, etc. The following description takes the connector including 4 terminals as an example. For example, the four terminals 1022 are: a first terminal 1022a (first power terminal (R1+)), a second terminal 1022b (first ground terminal (R1-)), a third terminal 1022c (second power terminal (R2+)) and a fourth terminal 1022d (second ground terminal (R2-)). The first terminal 1022a, the second terminal 1022b, the third terminal 1022c and the fourth terminal 1022d are installed in the base 1026 in sequence along the X direction.

[0132] In this embodiment, the first terminal 1022a is electrically connected to a positive pole of the network device 10, the second terminal 1022b is electrically connected to a negative pole of the network device 10, the third terminal 1022c is electrically connected to the other positive pole of the network device 10, and the fourth terminal 1022d is electrically connected to the other negative pole of the network device 10.

[0133] Among them, the first terminal 1022a is adjacent to the second terminal 1022b, and the third terminal 1022c is adjacent to the fourth terminal 1022d. The first terminal 1022a and the second terminal 1022b can serve as a set of positive and negative circuits, and the third terminal 1022c and the fourth terminal 1022d can serve as another set of positive and negative circuits.

[0134] The first positioning portion 10262 defines a first positioning hole 1023a for mounting the first terminal 1022a (first power terminal (R1+)), and a second positioning hole 1023b for mounting the second terminal 1022b (first ground terminal (R1-)). The openings of the first and second positioning holes 1023a, 1023b are located on the end surface of the first positioning portion 10262 facing away from the main body 10261. The first and second positioning holes 1023a, 1023b extend along the Z-axis direction.

[0135] The second positioning portion 10263 defines a third positioning hole 1023c for mounting the third terminal 1022c (second power terminal (R2+)) and a fourth positioning hole 1023d for mounting the fourth terminal 1022d (second ground terminal (R2-)). The openings of the third and fourth positioning holes 1023c and 1023d are located on the end surface of the second positioning portion 10263 facing away from the main body 10261. The third and fourth positioning holes 1023c and 1023d extend along the Z-axis direction.

[0136] Thus, the first wiring terminal 1022a, the second wiring terminal 1022b, the third wiring terminal 1022c and the fourth wiring terminal 1022d can be installed in sequence in the base 1026 along the X direction to form two sets of positive and negative circuits.

[0137] The present embodiment does not limit the structure of the terminal block 1022. In some embodiments, as shown in FIG18 , the terminal block 1022 includes: a fixed portion (a first fixed portion 10222 and a second fixed portion 10223) connected to each other and a connecting portion 10221. The connecting portion 10221 is connected to the cable 103. The fixed portion (the first fixed portion 10222 and the second fixed portion 10223) is configured to be inserted into the mounting hole 1024 of the base 1026 to mount the terminal block 1022 on the base 1026.

[0138] In this embodiment, each terminal block 1022 includes a connecting portion 10221 and a fixing portion (a first fixing portion 10222 and a second fixing portion 10223) connected to the connecting portion 10221. The connecting portion 10221 of the terminal block 1022 is used to contact the cable terminal 1031 of a cable 103, and the fixing portion (the first fixing portion 10222 and the second fixing portion 10223) of the terminal block 1022 is used to be installed on the base 1026. The material of each terminal block 1022 is a conductive material. Exemplarily, the material of each terminal block 1022 is copper. In other embodiments, the material of each terminal block 1022 can also be other conductive materials such as aluminum, and this application does not impose any limitation on this.

[0139] The following description uses the structure of the first terminal 1022a as an example. Other terminal blocks 1022 may have the same or similar structure as the first terminal 1022a, and reference may be made to the description of the first terminal 1022a. Please refer to FIG18 , which is a schematic diagram of the three-dimensional structure of the first terminal 1022a in the connector shown in FIG6 .

[0140] The first terminal block 1022a includes a connecting portion 10221 and a fixing portion. Specifically, there are two fixing portions: 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 square-shaped. The connecting portion 10221 is provided with a first connecting hole A, which extends through the connecting portion 10221 along the Z-axis. The first fixing portion 10222 is disposed on the side of the connecting portion 10221 facing the positive direction of the Y-axis, and the second fixing portion 10223 is disposed on the side of the connecting portion 10221 facing the negative direction of the Y-axis. The first fixing portion 10222 and the second fixing portion 10223 are spaced apart from each other. Each fixing portion (the first fixing portion 10222 and the second fixing portion 10223) has one end connected to the connecting portion 10221 and the other end extending along the Z-axis.

[0141] 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 the opposite two sides of the connecting portion 10221. The cross-sectional shape of the first terminal 1022a along the YZ plane is roughly C-shaped.

[0142] In other embodiments, the number of fixing parts (first fixing part 10222, second fixing part 10223) can also be one, three or four, etc. For example, the connecting part 10221 can connect one or more fixing parts (first fixing part 10222, second fixing part 10223).

[0143] The embodiment of the present application does not limit the sizes of the first fixing portion 10222 and the second fixing portion 10223. In some embodiments, the length of the first fixing portion 10222 can be smaller than the length of the second fixing portion 10223.

[0144] Furthermore, to facilitate insertion of the fixing portions (first fixing portion 10222 and second fixing portion 10223) into the positioning holes, in some embodiments, the end surfaces of the first fixing portion 10222 and / or the second fixing portion 10223, which are distal to the connecting portion 10221, are arc-shaped. Compared to square ends, arc-shaped ends provide better guidance, making it easier to insert the terminal block 1022 into the positioning hole of the base 1026.

[0145] In some embodiments, the fixing portion is further provided with a latching slot, which allows the latching slots of two adjacent terminals 1022 to be connected via a latching pin. This allows the adjacent terminals to be relatively fixed, preventing relative movement of the adjacent positive and negative terminals, and improving the stability of the electrical connection. Furthermore, connecting the two adjacent terminals via the latching pin prevents them from falling out of the positioning holes of the base.

[0146] For example, as shown in Figure 19, the first fixing portion 10222 of the first terminal 1022a and the first fixing portion 10222 of the second terminal 1022b are adjacent to each other. In order to improve the connection stability between the first terminal 1022a and the second terminal 1022b and the base 1026, the connector 1020 also includes: a first snap-in pin 1028, a first snap-in groove 10224a can be set on the first fixing portion 10222 of the first terminal 1022a, and a second snap-in groove 10224b can be set on the first fixing portion 10222 of the second terminal 1022b, so that the first snap-in pin 1028 can be snap-fitted with the first snap-in groove 10224a and the second snap-in groove 10224b.

[0147] This allows the first fixing portion 10222 of the first terminal 1022a and the first fixing portion 10222 of the second terminal 1022b to be relatively fixed, preventing relative movement of the adjacent positive and negative terminals 1022, thereby improving the stability of the electrical connection. Furthermore, the use of the snap-fit ​​pin to connect the two adjacent terminals 1022 prevents the first terminal 1022a and the second terminal 1022b from being dislodged from the positioning holes of the base 1026.

[0148] Correspondingly, the first fixing portion 10222 of the third terminal 1022c and the first fixing portion 10222 of the fourth terminal 1022d are adjacent to each other. In order to improve the connection stability between the third terminal 1022c and the fourth terminal 1022d and the base 1026, the connector 1020 also includes: a second snap-in pin (with the same or similar structure as the first snap-in pin, not shown in the figure). A third snap-in slot can be set on the first fixing portion 10222 of the third terminal 1022c, and a fourth snap-in slot can be set on the first fixing portion 10222 of the fourth terminal 1022d, so that the second snap-in pin can be snap-fitted with the third snap-in slot and the fourth snap-in slot.

[0149] This allows the first fixing portion 10222 of the third terminal 1022c and the first fixing portion 10222 of the fourth terminal 1022d to be relatively fixed, preventing relative movement of the adjacent positive and negative terminals 1022 and improving the stability of the electrical connection. Furthermore, connecting the two adjacent terminals 1022 via the second latching pin prevents the third terminal 1022c and the fourth terminal 1022d from being dislodged from the mounting hole 1024 of the base 1026.

[0150] The embodiments of this application do not limit the number of slots on the fixing portion. In some embodiments, for terminals located at the edge, a slot may be provided only on one side of the fixing portion closest to the adjacent terminal. For terminals located in the middle, slots may be provided on both sides of the fixing portion, forming a hammer shape. All of these fall within the scope of protection of this application.

[0151] The connection between the wiring terminal 1022 and the cable terminal 1031 is described below with reference to Figures 6 and 8. Referring 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 wiring terminal 1022.

[0152] In this embodiment, as shown in FIG8 , the cable 103 includes a first cable 103a, a second cable 103b, a third cable 103c, and a fourth cable 103d. The first cable 103a is connected to the first cable terminal 1031a shown in FIG6 , the second cable 103b is connected to the second cable terminal 1031b shown in FIG6 , the third cable 103c is connected to the third cable terminal 1031c shown in FIG6 , and the fourth cable 103d is connected to the fourth cable terminal 1031d shown in FIG6 .

[0153] Specifically, first cable terminal 1031a is electrically connected to first terminal 1022a (first power terminal (R1+)). Second cable terminal 1031b is electrically connected to second terminal 1022b. Third cable terminal 1031c is electrically connected to third terminal 1022c (second power terminal (R2+)) and third terminal 1022c. Fourth cable terminal 1031d is electrically connected to fourth terminal 1022d (second ground terminal (R2-)).

[0154] The cable terminals 1031 of each cable 103 are made of a conductive material. Exemplarily, each cable terminal 1031 is made of copper. When the cable terminals 1031 of the cable 103 come into contact with the wiring terminal 1022, current can flow between them, i.e., current can be transmitted between them. In other embodiments, the cable terminals 1031 of each cable 103 can also be made of other conductive materials such as aluminum, and this application does not impose any limitation on this.

[0155] During operation, the AC power 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 rectification by the power interface module 102, it is converted into DC power and fed to the device body 101, realizing the rectification function of the connector 1020.

[0156] To connect the cable terminal 1031 and the wiring terminal 1022, in some embodiments, the connector 1020 further includes a connector 1029. The connector 1029 is used to connect the wiring terminal 1022 to the cable terminal 1031, ensuring stable contact between the wiring terminal 1022 and the cable terminal 1031. There are multiple connectors 1029, and each wiring terminal 1022 is connected to the cable terminal 1031 of the cable 103 via a connector 1029. In this embodiment, the material of each connector 1029 can be conductive or insulating, and this application does not limit this.

[0157] In this embodiment, there are four connectors 1029, namely a first connector 1029a, a second connector 1029b, a third connector 1029c, and a fourth connector 1029d. The first connector 1029a is used to connect the first cable terminal 1031a of the first cable 103a to the first wiring terminal 1022a, the second connector 1029b is used to connect the second cable terminal 1031b and the second wiring terminal 1022b of the second cable 103b, the third connector 1029c is used to connect the third cable terminal 1031c of the third cable 103c to the third wiring terminal 1022c, and the fourth connector 1029d is used to connect the fourth cable terminal 1031d of the fourth cable 103d to the fourth wiring terminal 1022d.

[0158] 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, and the first wiring terminal 1022a, the second wiring terminal 1022b, the third wiring terminal 1022c, and the fourth wiring terminal 1022d have similar structures. To avoid redundancy, this document only describes in detail the connection between the first wiring terminal 1022a and the first cable terminal 1031a of the first cable 103a through the first connecting member 1029a.

[0159] The following description will take the connection of the first wiring terminal 1022a to the first cable terminal 1031a of the first cable 103a through the first connector 1029a as an example to achieve the connection with the first cable 103a.

[0160] In this embodiment, the connecting portion 10221 of the first terminal 1022a is provided with a first connecting hole A. The first connecting hole A extends through the connecting portion 10221 of the first terminal 1022a along the Z-axis. In this embodiment, the connecting portion 10221 of the first terminal 1022a is located between the base 1026 and the cover 1025. The first connecting hole A corresponds to the positioning hole 1023.

[0161] The first cable terminal 1031a is provided with a second connection hole B extending through the first cable terminal 1031a along the Z-axis. In this embodiment, the first cable terminal 1031a is located between the base 1026 and the first wiring terminal 1022a. The second connection hole B corresponds to the first connection hole A and the positioning hole 1023. The first connector 1029a is provided through the first connection hole A of the connecting portion 10221 and the second connection hole B of the first cable terminal 1031a, thereby electrically connecting the first cable terminal 1031a to the connecting portion 10221 of the wiring terminal 1022.

[0162] For example, the first connecting member 1029a passes through the first connecting hole A of the connecting portion 10221 of the wiring terminal 1022 and the second connecting hole B of the first cable terminal 1031a in sequence along the Z-axis direction, extends into the positioning hole 1023 of the first positioning portion 10262, and is screwed into the positioning hole 1023, so that the first cable terminal 1031a is clamped between the connecting portion 10221 and the connecting member 1029 installed on the first positioning portion 10262.

[0163] Thus, the first cable terminal 1031a is connected to the connecting portion 10221 of the wiring terminal 1022 via the first connector 1029a, so that the first cable terminal 1031a and the connecting portion 10221 of the wiring terminal 1022 are in stable contact with each other, thereby achieving stable current flow, that is, the first cable terminal 1031a is stably electrically connected to the connecting portion 10221 via the first connector 1029a.

[0164] 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.

[0165] For example, the connector 1029 includes a first stopper and a first threaded portion. The first threaded portion is located on the side of the first stopper facing the negative Z-axis direction and is fixedly connected to the first stopper. Along the Y-axis, the width of the first stopper is greater than the width of the first threaded portion. The outer circumference of the first threaded portion is threaded.

[0166] In some embodiments, as shown in Figure 20, the connector 1020 also includes: a nut 10260, the nut 10260 is embedded in the positioning hole 1023, the connecting member 1029 can be a bolt, the connecting member 1029 is provided with an external thread, and the connecting member 1029 can be threadedly connected to the nut 10260.

[0167] In this way, by setting the nut 10260 in the positioning hole 1023, the nut 10260 is clamped in the positioning hole 1023, and there is no need to set threads on the inner side of the positioning hole 1023, which reduces the process difficulty.

[0168] The embodiment of the present application does not limit the connection method between the nut 10260 and the positioning hole 1023. In some embodiments, as shown in Figure 20, the nut 10260 is snap-fitted to the positioning hole 1023. For example, the 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-sectional shape of the positioning hole 1023 can be a cross, a quadrilateral, a pentagon, a hexagon, 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 achieving stable flow of current between the first cable terminal 1031a and the first wiring terminal 1022a, that is, the first cable terminal 1031a and the first wiring terminal 1022a are stably electrically connected.

[0169] The first cable terminal 1031a is inserted into and mounted on the connecting portion 10221 between the connector 1029 and the wiring terminal 1022. The first threaded portion passes through the second connection hole B and the first connection hole A, sequentially along the Z-axis, and extends into the positioning hole 1023. The threads on the outer surface of the first threaded portion mate with the threads on the inner wall of the hole of the nut 10260, thereby achieving threaded engagement with the nut 10260. By rotating the first stopper along the thread direction of the first threaded portion, the first stopper moves along the Z-axis toward the base 1026, where it abuts against the first cable terminal 1031a.

[0170] At this point, the first cable terminal 1031a is clamped between the connector 1029 and the connecting portion 10221 of the terminal block 1022, ensuring stable contact between the first cable terminal 1031a and the connecting portion 10221 and preventing any shaking between the two. This allows for stable current flow between the first cable terminal 1031a and the first terminal block 1022a, i.e., a stable electrical connection between the first cable terminal 1031a and the first terminal block 1022a. Furthermore, because the width of the first stopper along the Y-axis is greater than the width of the first threaded portion, the first stopper acts as a stopper, facilitating assembly between the first connector 1029a and the connector 1029. The abutment between the first stopper and the connecting portion 10221 helps ensure stable contact between the first cable terminal 1031a and the connecting portion 10221, while also requiring low processing precision and resulting in low processing costs.

[0171] In the connector provided in this embodiment of the present application, the first connector 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 threadedly engaged with the nut 10260 in the positioning hole. The first retaining portion of the first connector 1029a abuts 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 achieving stable current flow. The first connector 1029a allows for quick connection between the first wiring terminal 1022a and the first cable terminal 1031a, reducing assembly difficulty and time. The simple structure makes it easy to manufacture and saves costs.

[0172] In the above embodiment, the fixing portions (first fixing portion 10222 and second fixing portion 10223) of the terminal block 1022 are installed in the base 1026. Specifically, the fixing portions (first fixing portion 10222 and second fixing portion 10223) of the terminal block 1022 can be inserted into the gap 10230 between the positioning hole 1023 and the nut 10260.

[0173] For example, as shown in Figure 20, the cross-section of the positioning hole 1023 is a "cross" shape, and the nut 10260 is square, including: a first side surface, a second side surface, a third side surface and a fourth side surface. The first side surface and the second side surface are arranged opposite to each other along the X direction, and the third side surface and the fourth side surface are arranged opposite to each other along the Y direction. When the nut 10260 is set in the positioning hole 1023, the first side surface and the second side surface are tightly attached to the inner wall of the positioning hole 1023, and a gap 10230 is set between the third side surface and the fourth side surface and the inner wall of the positioning hole 1023. The fixing part (first fixing part 10222, second fixing part 10223) of the terminal block 1022 is passed through the gap 10230 between the third side surface and the fourth side surface and the inner wall of the positioning hole 1023.

[0174] In order to improve the electrical connection stability of the terminal block 1022 , in some embodiments, as shown in FIG. 21 , a clip 10220 is provided on the fixing portion (first fixing portion 10222 , second fixing portion 10223 ) of the terminal block 1022 , and the clip 10220 is used to clip into the outer wall of the nut 10260 .

[0175] The embodiment of the present application does not limit the structure of the buckle 10220. For example, the buckle 10220 is protruding from the fixing portion (the first fixing portion 10222 and the second fixing portion 10223). The buckle 10220 can adopt an elastic structure. The embodiment of the present application does not limit the shape of the buckle 10220, and it can be circular, square, etc. The buckle 10220 is set on the inner wall of the fixing portion (the first fixing portion 10222 and the second fixing portion 10223) of the terminal block 1022. When the terminal block 1022 is installed on the base 1026, the inner wall of the fixing portion (the first fixing portion 10222 and the second fixing portion 10223) faces the outer wall of the nut 10260.

[0176] In some embodiments, a recess 10254 matching the buckle 10220 can be provided on the outer wall of the nut 10260 so that the buckle 10220 is engaged with the recess 10254 to improve the stability of the electrical connection.

[0177] The above embodiment is described by taking the connector including four connection terminals as an example. In other embodiments, as shown in FIG22 , the connector may include two connection terminals, and their structures may refer to the above embodiment and will not be described in detail here.

[0178] In another embodiment, as shown in FIG23 , the connector includes six terminals: a first terminal 1022a, a second terminal 1022b, a third terminal 1022c, a fourth terminal 1022d, a fifth terminal 1022e, and a sixth terminal 1022f. This differs from the above embodiment in that the terminals 1022 are arranged in two rows along the Y direction: the first terminal 1022a, the second terminal 1022b, the third terminal 1022c, and the fourth terminal 1022d form a first row along the X direction, and the fifth terminal 1022e and the sixth terminal 1022f form a second row along the X direction.

[0179] The first, second, third, and fourth wiring terminals 1022a, 1022b, 1022c, and 1022d may have the same structure as that shown in FIG18 . The fixing portions (10222 and 10223) of the first, second, third, and fourth wiring terminals 1022a, 1022b, 1022c, and 1022d may be spaced apart on opposite sides of the connecting portion 10221 along the Y direction, and the fixing portions (10222 and 10223) of the fifth and sixth wiring terminals 1022e, 1022f may be spaced apart on opposite sides of the connecting portion 10221 along the X direction. All of these fall within the scope of protection of this application.

[0180] In some embodiments, the end of the terminal block 1022 (the end of the fixed portion away from the connection portion) can also form a corner. The embodiment of the present application does not limit the direction of the corner and can be adjusted according to the circuit inside the device body. This application will not go into details. All of these fall within the scope of protection of this application.

[0181] Correspondingly, the connector also includes: a first positioning hole 1023a for installing the first terminal 1022a, a second positioning hole 1023b for installing the second terminal 1022b, a third positioning hole 1023c for installing the third terminal 1022c, a fourth positioning hole 1023d for installing the fourth terminal 1022d, a fifth positioning hole 1023e for installing the fifth terminal 1022e, and a sixth positioning hole 1023f for installing the sixth terminal 1022f.

[0182] Correspondingly, as shown in Figure 24, the connector also includes: a first mounting hole 1024a connected to the above-mentioned first positioning hole 1023a, a second mounting hole 1024b connected to the second positioning hole 1023b, a third mounting hole 1024c connected to the third positioning hole 1023c, a fourth mounting hole 1024d connected to the fourth positioning hole 1023d, a fifth mounting hole 1024e connected to the fifth positioning hole 1023e, and a sixth mounting hole 1024f connected to the sixth positioning hole 1023f.

[0183] 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 to install 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.

[0184] In order to avoid interference between the cables connected to the first row of terminals and the cables connected to the second row of terminals, the height of the mounting holes can be adjusted so that the height of the mounting holes of the first row of cables is different from the height of the mounting holes of the second row of cables. In this way, the cable terminals can be staggered in the Z direction to avoid interference.

[0185] For example, as shown in FIG24 , 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. 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.

[0186] 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.

[0187] 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.

[0188] The present invention provides a connector comprising: a housing, a plurality of wiring terminals, and a plurality of connectors. The housing is provided with a plurality of positioning holes, and the wiring terminals are mounted in the positioning holes. The housing is further provided with mounting holes communicating with the plurality of positioning holes, and the plurality of mounting holes are used to mount a cable. The wiring terminal is provided with a first connection hole corresponding to the positioning holes. The cable includes a cable terminal, and 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 to electrically connect the cable terminal to the wiring terminal. Each of the mounting holes includes at least two interconnected sub-mounting holes. Thus, the plurality of sub-mounting holes can be used to mount cables. When multiple connectors are installed on a network device, a connector with a corresponding cable outlet direction (mounting hole opening direction) can be selected based on the installation location. Therefore, a connector with multiple sub-mounting holes can be used in multiple different locations. Compared with the related art with a mounting hole having only one orientation, the connector does not need to be rotated when installed in different locations, reducing the risk of incorrect connection and minimizing safety hazards. Furthermore, no adapter is required for connection within the network device, which reduces costs and improves power supply reliability.

[0189] In some embodiments of the present application, each mounting hole includes two sub-mounting holes, with the angle between the two sub-mounting holes being 180°. This allows two connectors of this structure to be placed on opposite sides of a network device. After installation, the positive and negative power lines of the two connectors correspond, eliminating the risk of misconnection and reducing safety hazards. Furthermore, no adapters are required within the network device for connection, reducing costs and improving power supply reliability.

[0190] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
