Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a connector for transmitting power and signals. Background Technology

[0002] Connectors, also known as plugs and sockets, are a type of connector that integrates power and signal transmission into a single module. Traditional connectors consist of two separate modules for power and signal transmission, requiring simultaneous transmission of both. This results in a large footprint and high material consumption, making them difficult to meet market demands.

[0003] Connectors typically consist of a female and a male terminal. The female terminal connects to the device, while the male terminal connects to the external transmission line. During use, the pins on the male terminal are inserted into the sockets on the female terminal to achieve connection. Existing connector female terminal housings lack effective positioning or restraint for internal metal components. In particular, the sockets are prone to rotation during assembly, reducing assembly efficiency and hindering subsequent device connection operations. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0029] like Figures 1-9 As shown, a connector for transmitting power and signals includes a male terminal 1 and a female terminal 2. The male terminal 1 includes a male terminal housing and a first mounting base fixed inside the male terminal housing. A power pin 5 is positioned and mounted on the first mounting base by a first positioning component, and a signal pin 6 is fixedly mounted on the first mounting base by a first limiting component. The female terminal 2 includes a female terminal housing and a second mounting base fixed inside the female terminal housing. A power jack 3 is positioned and mounted on the second mounting base by a second positioning component, and a signal jack 4 is fixedly mounted on the second mounting base by a second limiting component.

[0030] like Figure 2 , Figure 3 As shown, the first mounting base includes a first mounting plate 7 and a first insulating plate 8. The male end housing includes a first upper shell 23 and a first lower shell 24. A first positioning component is disposed on the first mounting base, and a first limiting component is disposed between the first mounting plate 7 and the first insulating plate 8. When assembling the male end 1, one end of the signal pin 6 and one end of the power pin 5 are passed through the first mounting plate 7. At the same time, the power pin 5 is positioned on the first mounting base by the first positioning component. Then, the first mounting plate 7 is placed and supported on the top of the first lower shell 24. The first insulating plate 8 is placed on the top of the first mounting plate 7, so that the other end of the signal pin 6 and the other end of the power pin 5 pass through the first insulating plate 8. Finally, the first upper shell 23 is covered by the first mounting plate 7 and the first insulating plate 8 and fixedly connected to the first lower shell 24 by bolts, so that the bottom of the first insulating plate 8 abuts against the top of the first mounting plate 7. This completes the assembly and fixation of the first mounting base, and at the same time, the signal pin 6 is fixed by the first limiting component.

[0031] like Figure 6 , Figure 7As shown, the second mounting base includes a second mounting plate 9 and a second insulating plate 10. The female end housing includes a second upper shell 25 and a second lower shell 26. A second positioning component is disposed on the second mounting base, and a second limiting component is disposed between the second mounting plate 9 and the second insulating plate 10. When assembling the female end 2, one end of the signal jack 4 and one end of the power jack 3 are passed through the second mounting plate 9. Then, the second mounting plate 9 is placed inside the second lower shell 26, so that the second lower shell 26 covers the second mounting plate 9. Next, the second insulating plate 10 is placed on top of the second mounting plate 9, so that the other end of the signal jack 4 and the other end of the power jack 3 are passed through the second insulating plate 10, while the second lower shell 26 covers the second insulating plate 10. Finally, the second upper shell 25 covers the second insulating plate 10 and is fixedly connected to the second lower shell 26 with bolts, so that the bottom of the second insulating plate 10 abuts against the top of the second mounting plate 9. This completes the assembly and fixation of the second mounting base, and at the same time, the signal jack 4 is fixed by the second limiting component.

[0032] like Figure 5 As shown, the first positioning component includes a first countersunk hole and a first shaped block 11. The first mounting plate 7 has a first countersunk hole on its top surface, and the first shaped block 11 is integrally formed on the signal pin 6. During the assembly of the male terminal 1, the signal pin 6 is passed through the first countersunk hole through the first mounting plate 7, and the first shaped block 11 is embedded in the first countersunk hole. After the male terminal 1 is assembled, the bottom of the first insulating plate 8 simultaneously abuts against the top of the first mounting plate 7 and the shaped block, thereby completing the positioning and installation of the signal pin 6.

[0033] like Figure 9 As shown, the second positioning component includes a second countersunk hole and a second irregularly shaped block 12. The bottom surface of the second insulating plate 10 is provided with a second countersunk hole, and the signal socket 4 is integrally formed with the second irregularly shaped block 12. During the assembly of the female end 2, the signal socket 4 is passed through the second mounting plate 9. When the second insulating plate 10 is placed, the signal socket 4 passes through the second insulating plate 10 through the second countersunk hole, and at the same time, the second irregularly shaped block 12 is embedded in the second countersunk hole. After the assembly of the female end 2 is completed, the top of the second mounting plate 9 abuts against the bottom of the second insulating plate 10 and the irregularly shaped block, thereby completing the positioning and installation of the signal socket 4.

[0034] like Figure 3 , 4As shown, the first limiting component includes a first groove 13, a cone 14, a recess 15, an annular platform 16, a first annular groove 17, and a limiting ring 18. The first mounting plate 7 has a first groove 13 on its top, and a cone 14 is integrally formed at the bottom of the first groove 13. The bottom of the first insulating plate 8 has a recess 15 integrally formed. The outer wall of the power pin 5 has an annular platform 16 integrally formed. A first annular groove 17 is formed on the annular platform 16, and a limiting ring 18 is engaged in the first annular groove 17. During the assembly of male terminal 1, one end of power pin 5 passes through the first groove 13 and the cone 14 through the first mounting plate 7, and the ring 16 is inserted into the first groove 13. The other end of power pin 5 passes through the concave 15 through the first insulating plate 8. After the assembly of male terminal 1 is completed, the ring 16 abuts against the cone 14, and the end of the limiting ring 18 away from the cone 14 abuts against the concave 15, thereby achieving axial limiting of power pin 5. The first mounting plate 7 and the first insulating plate 8 simultaneously squeeze the limiting ring 18, thereby clamping the power pin 5 through the limiting ring 18 to prevent the power pin 5 from rotating at will, thereby achieving the fixation of the power pin 5.

[0035] like Figure 8 As shown, the second limiting component includes a second groove 19, a through hole 20, a cone 14, a second annular groove 21, and a C-shaped rubber ring 22. The second mounting plate 9 has a second groove 19 at its top and a through hole 20 at its bottom. The outer wall of the power pin 5 is integrally formed with the second annular groove 21, and a C-shaped rubber ring 22 is engaged within the second annular groove 21. One end of the C-shaped rubber ring 22 has a tapered outer wall. During the assembly of the female end 2, the C-shaped rubber ring 22 is engaged within the second annular groove 21, and the tapered outer wall of the C-shaped rubber ring 22 is positioned away from the through hole 20. Then, the power pin 3 passes through the through hole 20, the groove, the second mounting plate 9, and then the second insulating plate 10. The C-shaped rubber ring 22 is elastic and can be compressed and contracted into the second annular groove 21 by the wall of the through hole 20, thus facilitating the passage of the power pin 3 through the through hole 20. After the female end 2 is assembled, one end of the C-shaped rubber ring 22 near the through hole 20 abuts against the bottom of the second groove 19, and the bottom of the second insulating plate 10 abuts against the conical outer wall of the C-shaped rubber ring 22. The C-shaped rubber ring 22 can be squeezed to clamp the power socket 3. In this way, the power socket 3 is axially limited and prevented from rotating at will, thereby fixing the power socket 3.

[0036] The connector of this utility model has a compact and stable overall structure after assembly. By using the first and second mounting bases in conjunction with the first and second positioning components, the signal pins and signal sockets can be installed and positioned. By using the first and second mounting bases in conjunction with the first and second limiting components, the power pins and power sockets can be axially limited. At the same time, after the pins and sockets are installed, the power pins and power sockets can be prevented from rotating at will, which facilitates structural assembly, improves assembly efficiency, and makes subsequent operations such as connecting components more convenient and faster.

[0037] like Figure 1 As shown, the male terminal 1 is also equipped with a cover 27 on top. After the external transmission line is passed through the cover 27 and connected to the signal pin 6 and the power pin 5, the cover 27 is placed on the male terminal 1 and fixed to the first upper shell 23 with bolts, thereby protecting the wiring point. After the female terminal 2 is assembled, it is plugged into the working equipment. When power supply and signal transmission are required, the bottom of the second upper shell 25 is plugged into the top of the first lower shell 24, so that the power pin 5 is plugged into the power socket 3 and the signal pin 6 is plugged into the signal socket 4, thereby completing the docking of the male terminal 1 and the female terminal 2.

[0038] Finally, although embodiments of the present invention have been shown and described above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
