[0035] The above-mentioned antenna flexible circuit board 1 can be selected to be attached to the outer side of the housing 3 by means of adhesion. Of course, it can also be selected that the antenna flexible circuit board 1 is attached to the outer side of the housing 3 by means of screw or bolt connection; the conductive circuit board 2 can be selected to be attached to the inner side of the housing 3 by means of adhesion.

The conductive abutting point and the mounting hole projection are spaced apart on the conductive circuit board 2, that is, the abutting point of the conductive circuit board 2 and the elastic piece 41 is staggered relative to the mounting hole 31, so that the acting force of the elastic piece 41 is transmitted to the housing 3, avoiding the acting force from the elastic piece 41 being transmitted to the antenna flexible circuit board 1 through the mounting hole 31. The conductive abutting point and the mounting hole projection can be selected to be spaced apart in the length direction of the conductive circuit board 2. Of course, it can also be selected that the conductive abutting point and the mounting hole projection are spaced apart in the width direction of the conductive circuit board 2.

With such a setting, the first conductive portion 21 is disposed opposite to the mounting hole 31 to facilitate electrical connection with the antenna flexible circuit board 1, and the second conductive portion 22 is spaced from the first conductive portion 21 to prevent the acting force of the elastic piece 41 from being transmitted to the antenna flexible circuit board 1 through the mounting hole 31, or the acting force of the elastic piece 41 acts on the position of the conductive circuit board 2 opposite to the mounting hole 31, causing deformation and damage to the position of the conductive circuit board 2 opposite to the mounting hole 31.

[0043] Specifically, a circuit is provided on the conductive circuit board 2.

The elastic piece 41 abuts against the circuit in the rectangular area of the second conductive portion 22, so that the conductive circuit board 2 is electrically connected to the main board 4 through the elastic piece 41. Of course, the second conductive portion 22 can also be selected as a metal block or metal sheet, and the metal block or metal sheet is electrically connected to the first conductive portion 21.

[0045] The above-mentioned second conductive portion 22 can be selected to be spaced from the first conductive portion 21 in the length direction of the conductive circuit board 2. Of course, the second conductive portion 22 can also be selected to be spaced from the first conductive portion 21 in the width direction of the conductive circuit board 2, as long as the first conductive portion 21 and the second conductive portion 22 are spaced in a direction parallel to the conductive circuit board 2 on the conductive circuit board 2, so that the projection of the second conductive portion 22 on the inner side surface of the housing 3 in the direction of the conductive circuit board 2 towards the housing 3 is spaced from the mounting hole 31, preventing the acting force of the elastic piece 41 from being applied to the position of the conductive circuit board 2 opposite to the mounting hole 31, so that the housing 3 can bear the acting force of the elastic piece 41.

[0046] Refer to Figure 1 、 Figure 2 and Figure 4As shown, in some embodiments, the number of mounting holes 31 is two. The first conductive part 21 includes a first conductive end 211 and a second conductive end 212, and the second conductive part 22 includes a first abutting end 221 and a second abutting end 222. The two mounting holes 31 are arranged at intervals along the length direction of the conductive circuit board 2. The first conductive end 211 and the second conductive end 212 are arranged at intervals along the length direction of the conductive circuit board 2. The first abutting end 221 and the second abutting end 222 are arranged at intervals along the length direction of the conductive circuit board 2. The first conductive end 211 is electrically connected to the first abutting end 221, and the second conductive end 212 is electrically connected to the second abutting end 222. The first conductive end 211 and the first abutting end 221 are arranged at intervals along the width direction of the conductive circuit board 2. The second conductive end 212 and the second abutting end 222 are arranged at intervals along the width direction of the conductive circuit board 2. The first conductive end 211 and the second conductive end 212 are respectively arranged opposite to the two mounting holes 31. The first abutting end 221 and the second abutting end 222 are respectively used for abutting against the elastic piece 41.

[0047] With such an arrangement, the first conductive end 211 and the second conductive end 212 can respectively adapt to the two mounting holes 31. The antenna flexible circuit board 1 can be electrically connected to the positive electrode of the main board 4 through the first abutting end 221, the first conductive end 211 and the elastic piece 41, and the antenna flexible circuit board 1 can be electrically connected to the negative electrode of the main board 4 through the second abutting end 222, the second conductive end 212 and the elastic piece 41, which is convenient for forming a closed loop between the antenna flexible circuit board 1 and the main board 4.

[0048] Specifically, the two mounting holes 31 are arranged at intervals along the length direction of the conductive circuit board 2, and the distance between the two mounting holes 31 is equal to the distance between the first conductive end 211 and the second conductive end 212.

The copper pillar 11 passes through the mounting hole 31 to be connected to the conductive circuit board 2. With such a setting, the copper pillar 11 on the antenna flexible circuit board 1 has a certain structural strength. After the copper pillar 11 is inserted into the mounting hole 31, the copper pillar 11 can limit the antenna flexible circuit board 1, facilitating the determination of the position of the antenna flexible circuit board 1 outside the housing 3, and thus facilitating the adhesive connection between the antenna flexible circuit board 1 and the housing 3.

The length direction of the copper pillar 11 is consistent with the axial direction of the mounting hole 31, and the axial direction of the mounting hole 31 is the depth direction of the mounting hole 31. The length of the copper pillar 11 can be selected to be greater than the depth of the mounting hole 31, so that the copper pillar 11 can pass through the mounting hole 31, and one end of the copper pillar 11 is connected to the antenna flexible circuit board 1 and the other end is connected to the conductive circuit board 2. Or the length of the copper pillar 11 is equal to the depth of the mounting hole 31.

The conductive circuit board 2 is disposed in the second groove 33. The mounting hole 31 is provided at the bottom of the second groove 33. The conductive circuit board 2 is attached to the bottom of the second groove 33. With this arrangement, the second groove 33 has a positioning effect on the setting position of the conductive circuit board 2.
