[0033] Example 1

[0034] like Figure 1 , Figure 2 As shown, the terminal assembly provided in this embodiment includes an insulator 1 and a first terminal unit and a second terminal unit disposed on the insulator 1.

[0035] Based on the above structure, the terminal assembly uses a first terminal unit and a second terminal unit on the insulator 1 to transmit power and transmit signals, eliminating the need for additional independent wiring, making power and signal transmission more convenient and providing good sealing.

[0036] In some embodiments of this application, the first terminal unit includes a plurality of first terminal bodies 2 passing through the insulator 1.

[0037] like Figure 3 As shown, the first terminal body 2 is cylindrical and includes a pin and a plug. In use, the pin and plug are respectively placed in the male connector mechanism and the female connector mechanism, and the two are plugged together to achieve power transmission.

[0038] Specifically, the first terminal body 2 is provided with 7 terminals.

[0039] In some embodiments of this application, the second terminal unit includes a plurality of second terminal bodies 3 passing through the insulator 1.

[0040] like Figure 4 As shown, the second terminal body 3 is a multi-PIN signal connector, specifically configured with four sets, and has Ethernet functionality to enable signal transmission.

[0041] In some embodiments of this application, the distance between the first terminal body 2, the second terminal body 3 and the outer edge of the insulator 1 is greater than or equal to 1.0 mm.

[0042] When the distance between the first terminal body 2, the second terminal body 3, and the outer edge of the insulator 1 is small, the first terminal body 2 and the second terminal body 3 are prone to breakdown when the male and female connectors are plugged in to transmit power and signals, resulting in crosstalk between the transmitted signals and power.

[0043] In some embodiments of this application, a limiting member 21 is provided on the outer side of the first terminal body 2 and the second terminal body 3, and a limiting groove adapted to the limiting member 21 is provided inside the insulator 1.

[0044] The limiting member 21 on the outside of the first terminal body 2 is specifically a number of annular protrusions arranged on the outside of the cylindrical structure. The limiting member 21 on the outside of the second terminal body 3 is an elastic spring sheet. When the first terminal body 2 and the second terminal body 3 are assembled in the insulator 1, the limiting member 21 is engaged in the limiting groove to prevent the first terminal body 2 and the second terminal body 3 from axially sliding relative to the insulator 1 during use.

[0045] Furthermore, the positions of the limiting member 21 and the limiting groove can be interchanged, that is, the limiting member 21 is disposed inside the insulator 1, and the limiting groove is disposed on the first terminal body 2 and the second terminal body 3.

[0046] In some embodiments of this application, a locking bolt 4 is provided at the cable connection point on the first terminal body 2.

[0047] The locking bolt 4 is located on the cylindrical sidewall of the first terminal body 2 and can move radially therein. In use, first loosen the locking bolt 4, insert the cable into the first terminal body 2 and connect it, and then tighten the locking bolt 4 so that it moves radially along the first terminal body 2 to lock the cable therein and prevent the cable from detaching from the first terminal body 2 during use.

[0048] Example 2

[0049] like Figure 5 As shown, the female connector mechanism provided in this embodiment includes an outer shell 5, an inner shell 6, and the terminal assembly described in Embodiment 1. The inner shell 6 is disposed inside the outer shell 4, and the terminal assembly is disposed inside the inner shell 6.

[0050] This embodiment uses an outer shell 5 and an inner shell 6 to enclose the terminal assembly, thereby protecting the terminal assembly and improving the appearance of the female connector mechanism, making it more aesthetically pleasing and simple.

[0051] In some embodiments of this application, the insulator 1 in the terminal assembly is provided with a rear cover 7, and the locking bolt 4 is covered inside the rear cover 7.

[0052] The back cover 7 is a hollow cylindrical structure with one end folded towards the center to form a flange. When in use, the back cover 7 is fastened onto the insulator 1, with the flange abutting against the end of the insulator 1. The cylindrical sidewall of the back cover 7 contacts the outer side of the insulator 1. The back cover 7 is fitted onto the outside of the locking bolt 4. If the locking bolt 4 is not installed in place, the back cover 7 cannot be installed smoothly. Therefore, the back cover 7 can position the locking bolt 4 to ensure that the locking bolt 4 is installed in place.

[0053] In addition, the rear cover 7 is made of insulating material, which can isolate the locking bolt 4 from the inner housing 6 and ensure the safety of the female seat mechanism.

[0054] In some embodiments of this application, the inner wall of the inner housing 6 is provided with a positioning boss 61, and when the terminal assembly is installed in the inner housing 6, one end of the insulator 1 in the terminal assembly abuts against the positioning boss 61.

[0055] This embodiment can limit the installation position of the terminal assembly by setting the positioning boss 61, ensuring that the terminal assembly is installed in place and preventing the terminal assembly from slipping during use.

[0056] In some embodiments of this application, the cable positioning assembly 8 includes a tail cap 81 and a wire clamp 82 disposed within the tail cap 81. One end of the wire clamp 82 is connected to the inner wall of the inner housing 6, and the other end extends to the outside of the inner housing 6. When the tail cap 81 is threadedly connected to the inner housing 6, it causes the wire clamp 82 to tighten the cable therein in the direction of its axis.

[0057] This embodiment further clamps the cable connected to the terminal assembly by setting the cable positioning component 8, ensuring the stability of the connection between the cable and the first terminal body 2 and the second terminal body 3, and preventing the first terminal body 2 and the second terminal body 3 from detaching from the cable during use.

[0058] Example 3

[0059] like Figure 6 As shown, the male connector mechanism provided in this embodiment includes a male connector housing 9 and a terminal assembly as described in Embodiment 1. A limiting boss 91 is provided inside the male connector housing 9, and one end of the insulator 1 in the terminal assembly abuts against the limiting boss 91.

[0060] This embodiment uses a male connector housing 9 to enclose the terminal assembly, thereby protecting the terminal assembly and improving the appearance of the male connector mechanism, making it more aesthetically pleasing and simple.

[0061] By setting the limiting boss 91, the installation position of the terminal assembly can be limited, ensuring that the terminal assembly is installed in place and preventing the terminal assembly from slipping during use, thus ensuring reliable contact between the terminal assembly and the terminal assembly in the female seat mechanism.

[0062] In some embodiments of this application, an ear plate 92 is provided on the outer side of the male head housing 9, and a mounting hole 921 is provided on the ear plate 92.

[0063] In this embodiment, the mounting holes 921 on the ear plate 92 are aligned with the mounting holes on the equipment, and bolts and other connecting parts are inserted into the mounting holes to connect the male connector mechanism to the equipment. The disassembly and assembly process is convenient and facilitates the inspection and replacement of the male connector mechanism.

[0064] In some embodiments of this application, a dust cover 10 is also included, which is connected to the male head housing 9.

[0065] When the male and female connectors are used together, remove the dust cover 10 from the male connector. When they are not used together, fasten the dust cover 10 onto the male connector to prevent moisture and dust from damaging the male connector.

[0066] In addition, to prevent the dust cover 10 from being lost, the dust cover 10 is connected to one end of the connecting rope, and the other end of the connecting rope is connected to the male housing 9.

[0067] Example 4

[0068] like Figure 7 , Figure 8 As shown, the hybrid connector provided in this embodiment includes the female connector mechanism described in embodiment 2 and the male connector mechanism described in embodiment 3, wherein the female connector mechanism is adapted to the male connector mechanism.

[0069] In some embodiments of this application, the male housing 9 is provided with a guide groove, and the inner housing 6 is provided with a guide boss 62 that cooperates with the guide groove.

[0070] During assembly, the guide boss 62 is aligned with the guide groove, and then the inner housing 6 is inserted into the male housing 9. In use, this facilitates the alignment of the male and female connector mechanisms and prevents the terminal assembly from rotating relative to the male housing 9.

[0071] The specific method for using the hybrid connector provided in this embodiment is as follows:

[0072] Connect the ear plate 92 in the male connector mechanism to the equipment, remove the dust cover 10 on the male connector mechanism, insert the male connector mechanism into the female connector mechanism, wherein the inner shell 6 extends into the male connector shell 9, the outer shell 5 contacts the end of the male connector shell 9, the first terminal body 2 and the second terminal body 3 in the male connector mechanism respectively contact the first terminal body 2 and the second terminal body 3 in the female connector mechanism, and respectively use the first terminal body and the second terminal body 3 to realize power and signal transmission.

[0073] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
