[0026] In the existing terminal equipment, a grounding clip 1 is provided on the patch on the mainboard. The material of the grounding clip 1 is metal and is grounded with the mainboard. The grounding metal ring on the antenna cable contacts the grounding clip 1 to achieve the grounding of the antenna cable. The connector 2 in the terminal equipment includes a metal shell 3, which is screwed to the middle frame and grounded through the middle frame. Although the grounding effect of the metal shell 3 is very good, the antenna cable and the metal shell 3 are grounded separately.

[0027] Please refer to Figure 3 and Figure 4 , Figure 3 It is a schematic diagram of a partial structure of an electronic device 100 according to an exemplary embodiment of the present application. Figure 4 for Figure 3 FIG. 1 is a top view of a partial structure of an electronic device 100 shown in FIG.

[0028] The present application provides an electronic device 100, including an antenna coaxial cable 10 and a connector 20. The antenna coaxial cable 10 is used for antenna signal transmission. One end of the antenna coaxial cable 10 can be connected to the radio frequency circuit of the mainboard, and the other end is connected to the antenna radiator for feeding the antenna radiator. The antenna coaxial cable 10 also includes a metal grounding portion, which is used to achieve grounding of the antenna coaxial cable 10.

[0029] The antenna coaxial cable 10 is provided with a metal grounding portion 11. The specific implementation of the metal grounding portion 11 is not limited. For example, the metal grounding portion 11 may be a metal ring sleeved outside the antenna coaxial cable 10. For another example, the metal grounding portion 11 may be a copper leakage area. The connector 20 includes a connection terminal 21 and a metal shell 22 wrapped around the outer periphery of the connection terminal 21. The metal shell 22 is provided with an antenna grounding structure 23. The metal grounding portion 11 is in electrical contact with the antenna grounding structure 23, thereby achieving grounding of the antenna coaxial cable 10.

[0030] According to the above description, the metal grounding portion 11 of the antenna coaxial cable 10 is grounded by electrically contacting the antenna grounding structure 23 on the metal shell 22, which avoids interference with the antenna signal on the one hand, and saves the grounding wire clamp on the other hand, thereby reducing the pressure of laying out the grounding wire clamp on the mainboard and meeting the cost reduction requirements. The antenna grounding structure 23 is made of metal material, and the antenna grounding structure 23 is in electrical contact with the metal shell 22, and can be grounded through the metal shell 22.

[0031] In one embodiment, the antenna grounding structure 23 includes an electrical contact portion 231 and a limiting portion 232 connected to the electrical contact portion 231, the metal grounding portion 11 is in electrical contact with the electrical contact portion 231, and is grounded through the electrical contact portion 231, and the limiting portion 232 is used to limit the metal grounding portion 11 at the electrical contact portion 231. With this arrangement, the metal grounding portion 11 can better maintain contact with the electrical contact portion 231, and reliable grounding can be achieved.

[0032] In a specific embodiment, the limiting portion 232 includes a first limiting claw 2321 and a second limiting claw 2322, and the first limiting claw 2321 and the second limiting claw 2322 are arranged on both sides of the length direction of the electrical contact portion 231, and are used to jointly limit the metal grounding portion 11. In addition, the length direction of the metal grounding portion 11 is arranged to be consistent with the extension direction of the antenna coaxial cable 10. In this way, the first limiting claw 2321 and the second limiting claw 2322 can jointly limit the metal grounding portion 11 from both sides of the electrical contact portion 231, and the limiting is more reliable, and the grounding is also more reliable.

[0033] exist Figure 3In the embodiment shown, the first limiting claw 2321 and the second limiting claw 2322 are staggered along the length direction of the metal grounding portion 11, so that the metal grounding portion 11 is limited at two locations far apart, and the limiting effect is better. Of course, in some other embodiments, more limiting claws can be set.

[0034] In a specific embodiment, the middle portion of the electrical contact portion 231 protrudes from the metal shell 22, and a gap 233 is reserved between the electrical contact portion 231 and the metal shell 22, and both ends of the electrical contact portion 231 are connected to the metal shell 22. The gap can prevent the metal shell 22 from contacting the middle portion of the electrical contact portion 231, avoid interference between the two, and can also facilitate heat dissipation of the metal shell 22.

[0035] In one embodiment, the antenna grounding structure 23 and the metal shell 22 can be set as an integrated structure. For example, the antenna grounding structure 23 and the metal shell 22 are integrally processed and formed by machining, stamping, etc., simplifying the assembly process. In another embodiment, the antenna grounding structure 23 and the metal shell 22 can also be set separately, and the antenna grounding structure 23 is assembled to the metal shell 22 by assembly, which can simplify the processing technology and can also flexibly set the antenna grounding structure 23 according to actual needs.

That is, the metal shell 22 is fixed by the first metal sheet 221 and the second metal sheet 222 and grounded at the same time, and the grounding structure is stable and reliable. Figure 3 and Figure 4 In the illustrated embodiment, the first metal sheet 221 and the second metal sheet 222 are both provided with connection holes, through which screws can be inserted, so that the first metal sheet 221 and the second metal sheet 222 are fixed.

[0037] In one embodiment, the metal shell 22 includes a first arc portion 223 and a second arc portion 224 which are arranged opposite to each other in a first direction and are in an arc-shaped structure, and a first flat plate portion 225 and a second flat plate portion 226 which are arranged opposite to each other in a second direction and are in a flat plate-shaped structure, wherein the first direction is perpendicular to the second direction. The first metal sheet 221 is formed on the first arc portion 223, the second metal sheet 222 is formed on the second arc portion 224, and the antenna grounding structure 23 can be provided on the first flat plate portion 225 or the second flat plate portion 226.
