Referring to fig. 1 and 2, the present invention discloses an electronic device 10. In some embodiments, the electronic device 10 is a cell phone. The electronic device 10 includes a circuit board (not shown), an antenna radiator (not shown), and an antenna dome 11. The circuit board may be a printed circuit board that may integrate a processor, memory unit, power management unit, baseband chip, etc. of the electronic device 10. The antenna dome 11 is used to realize the conduction between the radio frequency circuit and the antenna radiator, so that the electronic device 10 can receive and transmit antenna signals through the antenna radiator. For example, in some embodiments, the rear cover 12 of the electronic device 10 is provided with an antenna radiator made of a metal material, the antenna elastic sheet 11 is disposed on a side of the circuit board facing the rear cover 12, and the antenna elastic sheet 11 abuts against the antenna radiator and maintains a proper pre-tightening force with respect to the antenna radiator, so that the antenna elastic sheet 11 and the antenna radiator maintain a reliable contact, and further the radio frequency circuit on the circuit board and the antenna radiator form a reliable electrical connection, so as to ensure reliability of the antenna radiator in receiving and transmitting antenna signals. In other embodiments, the electronic device 10 may be a tablet computer, a handheld game console, or a notebook computer, among others.

Referring to fig. 2 and 3, the antenna dome 11 includes a support portion 111, a guard arm 113 and an elastic arm 115, where the support portion 111 is used for connecting to a circuit board, and the elastic arm 115 is used for abutting against an antenna radiator. The two guard arms 113 are respectively connected to two opposite sides of the support portion 111, and form a substantially U-shaped limiting groove 11a together with the support portion 111. The elastic arm 115 is connected to the supporting portion 111 and bent relative to the supporting portion 111, and the elastic arm 115 is configured to swing relative to the supporting portion 111 in the limiting groove 11a when being pressed to approach the supporting portion 111, so as to generate an elastic force directed from the supporting portion 111 to the elastic arm 115. For example, in the embodiment where the rear cover 12 is provided with the antenna radiator, the antenna radiator presses the elastic arm 115, so that the elastic arm 115 swings toward the supporting portion 111 with respect to the supporting portion 111, and thus an elastic restoring force directed from the elastic arm 115 to the antenna radiator is generated, and the elastic restoring force is used to maintain the elastic arm 115 in reliable contact with the antenna radiator, thereby ensuring the reliability of the electrical connection.

In some embodiments, the guard arms 113 of opposite sides of the supporting portion 111 have the same shape, and the two guard arms 113 are symmetrically disposed about the supporting portion 111. The protective arm 113 can not only limit the lateral swing range of the elastic arm 115 to prevent the elastic arm 115 from moving in a larger space or interfering with other devices inside the electronic device 10 due to the lateral swing of the elastic arm 115, but also prevent the elastic arm 115 from swinging in a lateral direction to reduce the contact area between the elastic arm 115 and the metal radiator, thereby reducing the contact reliability between the elastic arm 115 and the metal radiator. Here, the lateral swing of the elastic arm 115 may be simply understood as a swing of the elastic arm 115 in a width direction of the support portion 111 (or a width direction of the stopper groove 11 a).

Further, at least one of a surface of the elastic arm 115 facing the guard arm 113 and a surface of the guard arm 113 facing the elastic arm 115 is provided with an insulating layer 117. For example, in the present embodiment, the support portion 111 has a substantially plate shape, the guard arms 113 are connected to both ends of the support portion 111 in the width direction, and the guard arms 113 are disposed substantially perpendicular to the support portion 111 and have a relatively large surface area on the side facing the elastic arms 115. The side of each arm guard 113 facing the spring arm 115 is provided with an insulating layer 117 to maintain reliable electrical insulation between the side of the spring arm 115 and the arm guard 113.

Further, in the present embodiment, the insulating layer 117 is a resin layer, and the thickness of the resin layer can be set to 0.01mm to 0.02mm, and the insulating layer 117 with such a thickness has relatively reliable insulating performance and low processing cost, and can reduce the gap between the elastic arm 115 and the guard arm 113. In other embodiments, the insulating layer 117 may be a ceramic layer, which may also ensure the insulating property between the elastic arm 115 and the guard arm 113, and the ceramic layer has relatively good wear resistance, so as to improve the reliability of the insulation and prevent the insulating layer 117 from being scratched to cause the accidental conduction between the guard arm 113 and the elastic arm 115. In other embodiments, the insulating layer 117 may be disposed on a surface of the elastic arm 115 facing the guard arm 113, or both the elastic arm 115 and the guard arm 113 may be disposed with the insulating layer 117 to ensure insulation reliability between the elastic arm 115 and the guard arm 113.

In the related art, in order to prevent the antenna performance from being reduced due to conduction between the elastic arm 115 and the guard arm 113 caused by the lateral swing of the elastic arm 115 in the process that the elastic arm 115 is pressed by the antenna radiator, the gap between the elastic arm 115 and the guard arm 113 needs to be set to be more than 0.5 mm. This structure causes the antenna dome 11 to occupy a relatively large installation space inside the electronic device 10. In the present embodiment, by providing the insulating layer 117 on at least one of the surface of the elastic arm 115 facing the guard arm 113 and the surface of the guard arm 113 facing the elastic arm 115, the gap between the elastic arm 115 and the guard arm 113 can be reduced while the insulating performance between the elastic arm 115 and the guard arm 113 is ensured. For example, in the present embodiment, the gap between the elastic arm 115 and the guard arm 113 may be reduced to 0.2mm or less. For example, in some embodiments, the gap between the elastic arm 115 and the guard arm 113 may be set to about 0.1mm, so that the occupied size of the antenna dome 11 is reduced, the installation space occupied inside the electronic device 10 is reduced, and the compactness of the layout of the devices inside the electronic device 10 is improved.

In the antenna spring 11 and the electronic device 10, the supporting portion 111 of the antenna spring 11 may be connected to a circuit board of the electronic device 10, and the elastic arm 115 may be abutted against an antenna radiator of the electronic device 10 so that the elastic arm 115 and the antenna radiator are reliably contacted. Since at least one of the surface of the elastic arm 115 facing the guard arm 113 and the surface of the guard arm 113 facing the elastic arm 115 is provided with the insulating layer 117, the elastic arm 115 can be reliably insulated from the guard arm 113 by the insulating layer 117, so as to reduce the gap between the elastic arm 115 and the guard arm 113, reduce the size of the antenna dome 11, and further reduce the installation space occupied by the antenna dome 11 inside the electronic device 10.

With continued reference to fig. 2 and 3, in the present embodiment, the support portion 111, the guard arms 113, and the elastic arms 115 are formed by press bending. For example, the whole copper foil material may be subjected to a press bending process to form the support portion 111, the guard arm 113, and the elastic arm 115 of the antenna dome 11. In other words, the supporting portion 111, the guard arm 113, and the elastic arm 115 are integrally formed, and the processing process of the antenna dome 11 is simple.

The elastic arm 115 further includes a connecting portion 1151 and an abutting portion 1153, the connecting portion 1151 is substantially U-shaped, and the opening of the U-shape faces the side of the guard arm 113. One end of the connecting portion 1151 is connected to the supporting portion 111, and the other end of the connecting portion 1151 is connected to the abutting portion 1153. The abutting portion 1153 is used for bearing the abutting force so as to swing relative to the supporting portion 111 in the limiting groove 11 a. Specifically, when the abutting portion 1153 is pressed, the width of the opening of the connecting portion 1151 is reduced, thereby generating elastic restoring force so that the abutting portion 1153 generates a force directed from the supporting portion 111 to the abutting portion 1153. The insulating layer 117 may be disposed on a surface of the abutting portion 1153 facing the guard arm 113.

Further, the holding portion 1153 is substantially V-shaped and includes a first arm 1153a and a second arm 1153 b. The V-shaped opening is directed to the side of the support 111. The first arm 1153a is connected between the connecting portion 1151 and the second arm 1153b, the first arm 1153a is bent relative to the connecting portion 1151 and protrudes from a side of the connecting portion 1151 away from the supporting portion 111, the second arm 1153b is bent relative to the first arm 1153a toward a side of the supporting portion 111, and at least a portion of the second arm 1153b extends into the limiting groove 11 a. The insulating layer 117 may be disposed on a surface of the second arm 1153b facing the guard arm 113. Of course, in the embodiment where the guard arm 113 has a wider width, at least a portion of the second arm 1153b may extend into the limiting groove 11a formed by two opposite guard arms 113, and the surface of the second arm 1153b facing the guard arm 113 may also be provided with an insulating layer 117 to ensure the insulating property between the second arm 1153b and the guard arm 113.

Further, in some embodiments, the antenna dome 11 further includes a stop portion 1155 disposed in the limiting groove 11a, and the stop portion 1155 is connected to an end of the second arm 1153b away from the first arm 1153 a. The guard arm 113 has a limiting hole 11b communicating with the limiting groove 11a, and the stopper 1155 is disposed through the limiting hole 11b to limit the swing range of the elastic arm 115 by the limiting hole 11 b. Specifically, when the abutting portion 1153 is not pressed, the blocking portion 1155 may abut against the hole wall of the limiting hole 11 b. The abutting force of the stopper portion 1155 against the hole wall of the stopper hole 11b can be obtained by elastic deformation of the connecting portion 1151 and the second arm 1153b with respect to the support portion 111. In other words, when the abutting portion 1153 is not abutted against the antenna radiator, the elastic arm 115 may slightly deform relative to the supporting portion 111 to generate an elastic restoring force, so that the abutting portion 1153 abuts against the hole wall of the limiting hole 11 b; after the abutting portion 1153 is pressed by the antenna radiator and swings to a side close to the supporting portion 111, the abutting portion 1153 may be separated from the hole wall of the limiting hole 11b, and at this time, the elastic restoring force generated by the elastic arm 115 is increased, so that the abutting portion 1153 may maintain reliable contact with the antenna radiator. Even when the stopper 1155 is separated from the hole wall of the stopper hole 11b, the stopper 1155 is prevented from being in communication with the guard arm 113, thereby ensuring the performance of the antenna.

Further, in the present embodiment, the stopper 1155 is bent toward the side of the connecting portion 1151 with respect to the second arm 1153b, and when the abutting portion 1153 is not pressed by the antenna radiator, the stopper 1155 is disposed parallel to the support portion 111, and the second arm 1153b is disposed perpendicular to the support portion 111. The structural arrangement can enable the elastic arm 115 to obtain a relatively large deformation space in the limiting groove 11a, and reduce the size of the antenna dome 11 in the length and width directions, so as to reduce the installation space occupied by the antenna dome 11.
