Abstract
Description
Technical Field
[0001] The present application relates to a power connector capable of combining multiple power cables to increase output current. Background Art
[0002] Due to the rapid development of technologies such as 5G, AI, edge computing, and IoT, data transmission speeds have increased several times, resulting in an increase in the power required, and in turn, a greater current supply is required.
[0003] In the prior art, when increasing current is needed, multiple power cables are often electrically connected to a single power terminal simultaneously to combine the currents of each power cable and increase the output current. A common design involves removing the insulation layer at one end of each power cable to expose the core wire. The exposed core wire is then riveted to a wire lug (also known as a terminal block or copper lug). A clamping plate is then used to clamp the lug between the power terminal and the clamping plate, and the three are then secured with bolts. However, this approach has the following disadvantages:
[0004] First, each power supply cable must be connected to a cable lug through riveting or other methods, and each cable lug must be locked to the power connector with a bolt. This results in numerous components, a complex structure, and a tedious assembly process. Second, the power supply cables are often arranged in a single horizontal spacing. Therefore, if a higher current is required and the number of power supply cables needs to be increased, the width of the power connector will increase significantly, which is not conducive to space utilization. Summary of the Invention
[0005] In view of the aforementioned shortcomings and deficiencies of the prior art, the present application provides a power connector assembly to simplify the overall structure and reduce the volume to make the overall structure more compact.
[0006] To achieve the above-mentioned application objectives, the technical means adopted in this application is to design a power connector assembly, which includes:
[0007] A housing having at least one wire entry port; and
[0008] a first power supply terminal including a first inner connecting portion and a first outer connecting portion, the first inner connecting portion being fixedly disposed inside the housing and having a first through-hole matrix facing the at least one wire inlet, the first through-hole matrix including a plurality of first through-holes, and the first outer connecting portion being located outside the housing;
[0009] a second power supply terminal including a second inner connecting portion and a second outer connecting portion, the second inner connecting portion being fixedly disposed inside the housing and having a second through-hole matrix facing the at least one wire inlet, the second through-hole matrix including a plurality of second through-holes, and the second outer connecting portion being located outside the housing;
[0010] a plurality of power supply cables, each power supply cable comprising at least one cable core, the cable core being welded into each of the first through hole or the second through hole of the power connector;
[0011] The first power supply terminal is located between the second power supply terminal and the at least one wire inlet and blocks a portion of the second power supply terminal, while allowing the second power supply terminal to expose the second through-hole matrix to the at least one wire inlet.
[0012] To achieve the above-mentioned application objectives, the present application further provides a power connector assembly, comprising:
[0013] A housing including a wire entry port;
[0014] a first power supply terminal including a first inner connecting portion and a first outer connecting portion, the first inner connecting portion being fixedly disposed inside the housing and including a first inner connecting plate having a plurality of first through holes, and the first outer connecting portion being located outside the housing;
[0015] a second power supply terminal including a second inner connecting portion and a second outer connecting portion, the second inner connecting portion being fixedly disposed inside the housing and including a second inner connecting plate having a plurality of second through holes, and the second outer connecting portion being located outside the housing;
[0016] The first inner connecting plate and the second inner connecting plate are spaced apart along the direction of the wire inlet, and the first inner connecting plate and the second inner connecting plate are staggered with each other so that the plurality of first through holes of the first power supply terminal and the plurality of second through holes of the second power supply terminal are respectively exposed toward the wire inlet;
[0017] A plurality of power supply cables are provided, wherein the cable cores of the plurality of power supply cables respectively pass through and are welded to the plurality of first through holes of the first power supply terminal and the plurality of second through holes of the second power supply terminal.
[0018] An advantage of a specific embodiment of the present application is that, by forming a through-hole in the power supply terminal, the core of the power supply cable can be directly passed through and welded into the through-hole to secure the power supply cable to the power supply terminal, thereby greatly simplifying the connection structure between the power supply cable and the power supply terminal. Furthermore, by providing two power supply terminals arranged front and back and staggered up and down, and each power supply terminal having multiple through-holes for connecting multiple power supply cables, and the first power supply terminal located in the middle being positioned so as not to block the power supply cable of the second power supply terminal, the power supply cables of the power supply terminals can be staggered to achieve an arrangement similar to that of overlapping power supply cables. This allows for more power supply cables to be more compactly accommodated within a limited space, thereby increasing the output current.
[0019] The present application effectively utilizes space, increases output current, and further achieves the application objectives of reducing the number of components, simplifying the structure and assembly process.
[0020] Furthermore, the power connector, wherein: the first inner connection portion includes a first inner connection plate, the first through-hole matrix is formed on a first plane of the first inner connection plate; and the second inner connection portion includes a second inner connection plate, the second through-hole matrix is formed on a second plane of the second inner connection plate; wherein the normal vector directions of the first plane and the second plane respectively pass through the at least one wire entry port.

[0023] Furthermore, the power connector described above, wherein the shell includes a rectangular structure, including a first end plane and a second end plane, the normal vector directions of the first end plane and the second end plane are perpendicular to each other, the first end plane is provided with at least one wire inlet; the second end plane is provided with at least one wire outlet for allowing the first external connection part and the second external connection part to pass through the shell.
[0024] Furthermore, in the power connector, two limiting grooves are provided on the inner wall surface of the shell, and the opposite sides of the first power supply terminal are respectively inserted and engaged in the two limiting grooves.
[0025] Furthermore, in the power connector, a support portion is respectively protruded from the two limiting grooves, and the first power terminal abuts against the two support portions in the two limiting grooves so that the first power terminal and the second power terminal are located at different heights.
[0026] Furthermore, the power connector further includes a cover, a surface of which is provided with a protruding structure. When the cover is covered on a port of the housing, the protruding structure separates the first power supply terminal and the second power supply terminal. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following, in conjunction with the accompanying drawings and the preferred embodiments of this application, further explains the technical means adopted by this application to achieve the predetermined application purpose.
[0035] See also Figure 1 and Figure 2 As shown, in one embodiment of the present application, a power connector assembly includes a power connector and a plurality of power cables 40, wherein the power connector includes a housing 10, a first power terminal 20, and a second power terminal 30. The power connector is a power supply connector, not a signal transmission connector. Therefore, the terminals included in the power connector are power terminals and do not include signal terminals, and the cables are power cables and do not include signal cables.
[0036] See also Figures 2 to 4 As shown, the housing 10 is provided with at least one cable inlet 13 and at least one cable outlet 14. In this embodiment, there is one cable inlet 13 for all power cables 40 to pass through, and two cable outlets 14 for the first power terminal 20 and the second power terminal 30 to pass through, respectively. However, the present invention is not limited to this. Multiple cable inlets 13 may be provided to allow multiple power cables 40 to pass through separately, and a single cable outlet 14 may be provided to allow the first power terminal 20 and the second power terminal 30 to pass through together.
[0037] In this embodiment, the housing 10 includes a rectangular structure, including a first end plane 11 and a second end plane 12. The first end plane 11 is a plane for setting the wire inlet 13, and the second end plane 12 is a plane for setting the wire outlet 14. The normal vector directions of the first end plane 11 and the second end plane 12 are perpendicular to each other, that is, the wire inlet 13 and the wire outlet 14 are respectively located on mutually perpendicular planes, but the positions of the wire inlet 13 and the wire outlet 14 are not limited to this.
[0038] In this embodiment, the housing 10 includes an open port 15 , and the port 15 is covered by a cover 50 . Preferably, the housing 10 and the cover 50 together form the wire inlet 13 , but the present invention is not limited thereto. The wire inlet 13 may also be formed separately on the housing 10 .
[0039] See also Figure 2 、 Figure 3 and Figure 5 As shown, the aforementioned first power supply terminal 20 includes a first inner connecting portion 21 and a first outer connecting portion 22. The first inner connecting portion 21 is fixedly arranged inside the housing 10 and is provided with a first through-hole matrix 24 facing the line inlet 13. The first through-hole matrix 24 includes a plurality of first through-holes 241. The first through-hole matrix 24 is MxN, where either M or N can be one and the other can be at least two. Each first through-hole 241 is used for passing one of the power supply cables 40. In this embodiment, in order to increase the total amount of current that each power supply cable 40 can support, a cable core 41 with a diameter greater than or equal to 2 mm is used. Correspondingly, as shown in FIG. Figure 5 As shown, in this embodiment, the minimum aperture of the first through hole 241 is greater than or equal to 2 mm. The minimum aperture can be understood as the minimum straight-line distance between any two points (not limited to the same surface) passing through the axis of the hole to allow the aforementioned cable core 41 to pass through. However, the diameter or minimum aperture of the aforementioned cable core 41 is not limited to the aforementioned values. The first external connection portion 22 is located outside the housing 10. Specifically, the first external connection portion 22 passes through the cable outlet 14 of the housing 10 and extends outside the housing 10 to serve as a male output.
[0040] In this embodiment, the first power supply terminal 20 further includes a first intermediate portion 23 connected between the first inner connecting portion 21 and the first outer connecting portion 22. Preferably, the first inner connecting portion 21 and the first outer connecting portion 22 are both bent vertically relative to the first intermediate portion 23, so that the first intermediate portion 23 can be attached to the inner wall surface of the housing 10 or the cover 50 (such as Figure 7 As shown in FIG, the first power supply terminal 20 can be further stably arranged. However, the specific structure and shape of the first power supply terminal 20 are not limited to the above.
[0041] See also Figure 2 、 Figure 3 and Figure 5As shown, the aforementioned second power supply terminal 30 includes a second inner connecting portion 31 and a second outer connecting portion 32. The second inner connecting portion 31 is fixedly mounted inside the shell 10 and is provided with a second through-hole matrix 34 facing the line inlet 13. In this embodiment, the design of the second through-hole matrix 34 and the second through-holes 341 therein are the same as the first hole matrix 24 and the first through-holes 241. The second through-hole matrix 34 includes a plurality of second through-holes 341. The second through-hole matrix 34 is MxN, where either M or N can be one, and the other is at least two. Each second through-hole 341 is used for one of the power supply cables 40 to pass through. In this embodiment, in order to increase the total amount of current that each power supply cable 40 can support, a cable core 41 with a diameter greater than or equal to 2 mm is used. Correspondingly, as shown in FIG. Figure 5 As shown, in this embodiment, the minimum aperture of the second through hole 341 is greater than or equal to 2 mm. The minimum aperture can be understood as the minimum straight-line distance between any two points (not limited to the same surface) passing through the axis of the hole to allow the aforementioned cable core 41 to pass through. However, the diameter or minimum aperture of the aforementioned cable core 41 is not limited to the aforementioned values. The second external connection portion 32 is located outside the housing 10. Specifically, the second external connection portion 32 extends outside the housing 10 through the cable outlet 14 of the housing 10 and serves as a male output.
[0042] In this embodiment, the second power supply terminal 30 further includes a second intermediate portion 33 connected between the second inner connecting portion 31 and the second outer connecting portion 32, and preferably, the second inner connecting portion 31 and the second outer connecting portion 32 are both bent vertically relative to the second intermediate portion 33, whereby the second intermediate portion 33 can be abutted against the inner wall surface of the housing 10 or the cover 50 (such as Figure 7 As shown in FIG, the second power supply terminal 30 can be further stably arranged. However, the specific structure and shape of the second power supply terminal 30 are not limited to the above.
[0043] See also Figure 5 and Figure 7 As shown, the first power supply terminal 20 is located between the second power supply terminal 30 and the wire inlet 13 of the housing 10 and blocks a portion of the second power supply terminal 30. At the same time, the first power supply terminal 20 allows the second power supply terminal 30 to expose the second through-hole matrix 34 of the second power supply terminal 30 to the wire inlet 13. In this way, the first power supply terminal 20 will not block the power supply cable 40 connected to the second through-hole matrix 34 of the second power supply terminal 30 through the wire inlet 13. In other words, when looking inward from the wire inlet 13 of the housing 10, both the first through-hole matrix 24 and the second through-hole matrix 34 can be seen (as shown in FIG. Figure 5 shown).
[0044] See also Figure 2 、 Figure 6 and Figure 7As shown, in this embodiment, the first inner connecting portion 21 of the first power supply terminal 20 includes a first inner connecting plate 211, with a first through-hole matrix 24 formed on a first plane of the first inner connecting plate 211. The second inner connecting portion 31 of the second power supply terminal 30 includes a second inner connecting plate 311, with a second through-hole matrix 33 formed on a second plane of the second inner connecting plate 311. The normal vectors of the first plane of the first inner connecting plate 211 and the second plane of the second inner connecting plate 311 respectively extend through the cable entry 13 of the housing 10. In other words, if the power cable 40 passes perpendicularly through the first inner connecting plate 211 and the second inner connecting plate 311, the extension direction of the power cable 40 will be perpendicular to the cable entry 13, thereby preventing the power cable 40 from being skewed relative to the cable entry 13. However, this is not limiting; if other requirements are met, the design can also allow the power cable 40 to pass through the cable entry 13 skewed relative to the cable entry 13.
[0045] The first inner connecting plate 211 of the first power supply terminal 20 and the second inner connecting plate 311 of the second power supply terminal 30 are spaced apart along the direction of the wire inlet 13 of the housing 10. The first inner connecting plate 211 and the second inner connecting plate 311 are staggered with each other so that the first through holes 241 of the first power supply terminal 20 and the second through holes 341 of the second power supply terminal 30 are exposed to the wire inlet 13 (as shown in FIG. Figure 5 shown).
[0046] See also Figure 2 and Figure 3 As shown, in addition, in this embodiment, the first power supply terminal 20 and the second power supply terminal 30 are both integrally formed. The integrally formed first power supply terminal 20 means that the first power supply terminal 20 exists in the form of a single material block, or it is connected together by multiple components to form a complete part or unit, and the component cannot be easily disassembled without destroying the integrity of the part or unit (for example, it can be welded by multiple components).
[0047] See also Figure 3 and Figure 7 As shown, in this embodiment, a protruding structure 51 is provided on the surface of the cover 50. When the cover 50 is covered on the port 15 of the housing 10, the protruding structure 51 separates the first power supply terminal 20 and the second power supply terminal 30 (as shown in FIG. Figure 7 As shown), the first power supply terminal 20 and the second power supply terminal 30 are prevented from accidentally contacting each other due to various reasons.
[0048] See also Figure 2 、 Figure 3 、 Figure 6 and Figure 8As shown, in this embodiment, two retaining groove sets 16 are provided on the inner wall surface of the housing 10, corresponding to the first power terminal 20 and the second power terminal 30, respectively. Each retaining groove set 16 includes two retaining grooves 161, which are respectively provided on opposite sides of the inner wall surface of the housing 10. The first power terminal 20 or the second power terminal 30 is respectively inserted and engaged with the two retaining grooves 161 on opposite sides, thereby firmly positioning the first power terminal 20 and the second power terminal 30. In this embodiment, each retaining groove 161 includes two ribs protruding from the inner wall surface of the housing 10 to form a groove, but this is not limited to this. The retaining grooves 161 can also be directly recessed into the inner wall surface of the housing 10.
[0049] In addition, further, each limiting groove 161 of the limiting groove group 16 corresponding to the first power supply terminal 20 (located between the second power supply terminal 30 and the wire inlet 13) is respectively provided with a support portion 162 protruding therein. The first power supply terminal 20 is supported by the two support portions 162 in the two limiting grooves 16, thereby enabling the first power supply terminal 20 and the second power supply terminal 30 to be located at different heights (e.g. Figure 8 As shown), the first power supply terminal 20 is prevented from blocking the power supply cable 40 to the second power supply terminal 30.
[0050] See also Figure 3 、 Figure 6 and Figure 7 As shown, the aforementioned multiple power supply cables 40 are respectively inserted through the first through-hole 241 and the second through-hole 341. Each power supply cable 40 includes at least one cable core 41. The cable core 41 of each power supply cable 40 is inserted through and welded to the first through-hole 241 of the corresponding first power supply terminal 20 or the second through-hole 341 of the second power supply terminal 30. In this way, each power supply terminal 20, 30 can accumulate the current of the multiple power supply cables 40 inserted through and welded thereto and output it through the external connection parts 22, 32. The output voltage is still the same as the voltage of each power supply cable 40. The two power supply terminals 20, 30 can be used as the live wire (usually represented by L) and the neutral wire (usually represented by N), respectively.
[0051] During assembly, it is preferred to first thread multiple power cables 40 through and solder them to the first power terminal 20 or the second power terminal 30. The two power terminals 20 and 30 are then placed into the housing 10 through the port 15, and finally, the cover 50 is closed. This allows the first and second external connectors 22 and 32 of the two power terminals 20 and 30, which pass through the cable outlet 14, to serve as output connectors, simultaneously integrating the current of multiple power cables to increase output current.
[0052] In the present application, through holes 241 and 341 are formed on the power supply terminals 20 and 30, so that the cable core 41 of the power supply cable 40 can be directly passed through the through holes 241 and 341 and welded to fix the power supply cable 40 on the power supply terminals 20 and 30, thereby greatly simplifying the connection structure between the power supply cable 40 and the power supply terminals 20 and 30.
[0053] Furthermore, by providing two power supply terminals 20 and 30, and each power supply terminal 20 and 30 is provided with multiple through holes 241 and 341 for connecting multiple power supply cables 40, and the first power supply terminal 20 located in the middle is arranged at a position that does not block the power supply cable 40 of the second power supply terminal 30, the power supply cables 40 of the two power supply terminals 20 and 30 can be staggered to achieve an arrangement similar to the power supply cables 40 overlapping each other, thereby more power supply cables can be more compactly accommodated within a limited space, thereby increasing the output current (increasing the number of power supply cables is the only way to increase the output current).
[0054] The present application effectively utilizes space, increases output current, and further achieves the application objectives of reducing the number of components, simplifying the structure and assembly process.
[0055] The above description is merely a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as a preferred embodiment, it is not intended to limit the present application. Any technician in the relevant technical field can make slight changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present application. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
