For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Figure 1 is an exploded schematic diagram of a local area network adapter in the present invention; Figure 2 is a cross-sectional view of a local area network adapter in the present invention; Figure 3 It is a three-dimensional local area network adapter in the present invention. Figure 1 ; Figure 4 It is a three-dimensional local area network adapter in the present invention. Figure 2 ; Figure 5 This is a diagram showing the use status of the LAN adapter in the present invention. Figures 1 to 5 As shown, a preferred embodiment is shown, which shows a local area network adapter, including a housing 1, an outer conductor 2, a fastener 3, an insulator 4 and a center conductor 5. The outer conductor 2 is arranged inside the housing 1 and is limited by the inner wall of the housing 1. The insulator 4 is arranged inside the outer conductor 2 and is limited by the outer conductor 2 through the fastener 3. The center conductor 5 is installed in the insulator 4. In this embodiment, see Figure 2As shown, the center conductor 5 is installed inside the insulator 4, and then the insulator 4 is matched with the second limiting surface 11 in the outer conductor 2 through the fastener 3 to achieve the installation and limiting of the insulator 4. The insulator 4 can be stably installed in the outer conductor 2, and the outer conductor 2 is installed inside the shell 1 to limit the first limiting surface 6 on the inner wall of the shell 1, so that the center conductor 5 can be stably installed inside the shell 1, and the outer conductor 2 is made of lead brass and is covered with a nickel-gold plating layer on its surface, which can meet the neutral salt spray test for 96 hours. In addition, the use of lead brass material can increase a certain degree of hardness support. When violent dismantling occurs between the adapter and the external connector 15, a certain degree of hardness support can be provided to prevent deformation of the center conductor 5. The center conductor 5 and the insulator 4 have an interference fit, and the insulator 4 and the outer conductor 2 have a limited fit, and the outer conductor 2 and the shell 1 also have a limited fit. This facilitates rapid installation or disassembly of the various structures, and the structure is stable. When encountering violent disassembly between the adapter and the connector 15, the position of the center conductor 5 will not be offset.

[0026] Further, as a preferred embodiment, the inner wall of the housing 1 is provided with a first limiting surface 6, and the outer wall of the outer conductor 2 is provided with a first protrusion 7, and one side of the first protrusion 7 abuts against the first limiting surface 6. Figure 1 As shown, the first protrusion 7 is arranged in an annular shape as a whole, and can be connected to the outer conductor 2 in an integral manner, and the first limiting surface 6 of the inner wall of the housing 1 forms a first step portion, which abuts against the first protrusion 7 on the outer conductor 2 to limit the installation position of the outer conductor 2. At the same time, in conjunction with the setting of the limiting protrusion 8 on the inner wall of the housing 1 and the limiting groove 9 on the side wall of the first protrusion 7, after the outer conductor 2 is installed in place, the limiting protrusion 8 just enters the limiting groove 9 to lock the position of the outer conductor 2, so that the outer conductor 2 is installed more stably inside the housing 1, and see Figure 1 It can be seen that the cross section of the first protrusion 7 is elliptical, and this shape can prevent the outer conductor 2 from rotating inside the housing 1. In other embodiments, the cross section of the first protrusion 7 can be rectangular or other shapes, as long as the outer conductor 2 can be prevented from rotating inside the housing 1. And the outer wall of the first protrusion 7 is in contact with the inner wall of the housing 1, which can prevent the outer conductor 2 from shaking. The setting position of the limiting protrusion 8 on the inner wall of the housing 1 can be seen in Figure 2 As shown, the position of the limiting groove 9 on the first protrusion 7 can be seen in Figure 2 shown.

[0027] Further, as a preferred embodiment, a second protrusion 10 is provided on the outer wall of one end of the insulator 4, a second limiting surface 11 is provided on the inner wall of the outer conductor 2, and one side of the second protrusion 10 abuts against the second limiting surface 11. Figure 1 and Figure 2 As shown, the second limiting surface 11 on the inner wall of the outer conductor 2 is raised to form a second step portion, which is used to abut against the second protrusion 10 to limit the position of the insulator 4, wherein the second protrusion 10 and the insulator 4 can be connected in one piece, and the cross-section of the second protrusion 10 can be elliptical or rectangular, which can prevent the insulator 4 from rotating inside the outer conductor 2, and the outer wall of the second protrusion 10 is in contact with the inner wall of the outer conductor 2, which can prevent the insulator 4 from shaking inside the outer conductor 2. Such cooperation can make the structure more stable after installation.

[0028] Further, as a preferred embodiment, a slot 12 is provided on the inner wall of the outer conductor 2, and the fastener 3 is disposed in the slot 12 and abuts against the other side of the second protrusion 10. Figure 1 and Figure 2 As shown, the fastener 3 is an elliptical ring structure with one side open. Of course, the specific shape of the fastener 3 can be selected according to the shape of the slot 12. The slot 12 is an annular groove. When the insulator 4 is installed inside the outer conductor 2, the second protrusion 10 abuts against the second limiting surface 11, and then the fastener 3 is installed so that the fastener 3 enters the slot 12. At this time, the fastener 3 abuts against the second protrusion 10 to fix the position of the insulator 4.

[0029] Further, as a preferred embodiment, a through hole 13 is provided inside the insulator 4, the center conductor 5 is arranged in the through hole 13 and has an interference fit with the through hole 13, and one end of the center conductor 5 extends out of the insulator 4. In this embodiment, the center conductor 5 is made of phosphor bronze and nickel-plated on the outer layer, and the outer wall of the part where the center conductor 5 and the external connector 15 are matched can be gold-plated to enhance the high-frequency performance of the center conductor 5. In addition, the center conductor 5 and the insulator 4 have an interference fit, and one end of the center conductor 5 extends out of the insulator 4 to ensure that the insulator 4 is not damaged during the assembly process.

[0030] Further, as a preferred embodiment, a guide surface is provided at the outer edge of one end of the through hole 13. The guide surface can be an inclined surface or a flat surface, mainly to facilitate the central conductor 5 to enter the through hole 13 and guide the central conductor 5 to enter the through hole 13.

[0031] Furthermore, as a preferred embodiment, the outer edge of the opening at one end of the outer conductor 2 is provided with a chamfer, and the chamfer is provided to facilitate the insulator 4 to enter the outer conductor 2.

[0032] Further, as a preferred embodiment, a plurality of guide limit blocks are disposed on the outer wall of one end of the housing 1, and two clamping parts 14 are disposed at both ends of the housing 1. The structure of the clamping part 14 can be seen in Figure 3 and Figure 4 As shown, and see Figure 5 As shown, the clamping portion 14 is provided to cooperate with the clamping block on the connector 15 to facilitate connecting the connector 15 and the adapter together.

[0033] The adapter in this embodiment can cooperate with the advanced driver assistance system, the on-board diagnostic system and the on-board entertainment system which need to use the Gigabit Ethernet connector 15 to realize the switching function and realize the transmission of signals.

[0034] During assembly, first install the center conductor 5 at the specified position in the through hole 13, then press the insulator 4 into the outer conductor 2, so that the second protrusion 10 on the insulator 4 abuts against the second limiting surface 11 on the inner wall of the outer conductor 2, then assemble the fastener 3, push the fastener 3 into the slot 12, so that the fastener 3 abuts against the second protrusion 10, and the insulator 4 is installed, and then the outer conductor 2 is pressed into the shell 1, so that the first protrusion 7 on the outer conductor 2 abuts against the first limiting surface 6 on the inner wall of the shell 1, ensuring that the limiting protrusion 8 enters the limiting groove 9 at this time, thereby achieving the assembly between the outer conductor 2 and the shell 1, and then plug the two clamping parts 14 on the shell 1 into the two connectors 15 that need to be connected. Among them, the shapes and structures of the two clamping parts 14 are somewhat different, and their specific structures and shapes can be seen in Figure 3 and Figure 4 As shown, connection between two different types of connectors 15 can be achieved. Of course, in other embodiments, the structures and shapes of the two clamping parts 14 can also be completely the same.

For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
