Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Unless otherwise specified, use of the terms of orientation such as "upper, lower, left, right" are defined according to the directions indicated in the respective drawings, and "inner" and "outer" refer to the inner and outer of the contours of the respective parts themselves. Furthermore, the terms "first," "second," and the like, as used herein, are intended to distinguish one element from another, and not necessarily to distinguish between order and importance.

As shown in fig. 1 and 2, the present disclosure provides a terminal device antenna for being provided in a terminal device to transmit a signal. The terminal device includes, but is not limited to, electronic devices such as a mobile phone, a notebook computer, a tablet computer, and the like. The terminal device antenna comprises a first antenna support 1, a first flexible circuit board 3 and a metal shell 4. The first flexible circuit board 3 is connected with the metal shell 4, and the first antenna support 1 is connected with the flexible circuit board 3 through the metal elastic sheet 2 so as to form a grounding circuit which is sequentially the first antenna support 1, the metal elastic sheet 2, the first flexible circuit board 3 and the metal shell 4. That is, it can be considered that the first antenna holder 1 is indirectly connected to the metal case 4 through the metal dome 2 and the first flexible circuit board 3 to achieve grounding. It should be noted that, the Z direction in the drawing, i.e. the thickness direction of the terminal device, saves the space occupied by the antenna in the Z direction, and is beneficial to the limit design of the thickness of the terminal device.

The first flexible circuit board 3 is used for mounting the connector 6, and the connector 6 has the characteristic of miniaturization, and has gradually replaced the traditional mode that coaxial lines are used for radio frequency signal transmission. In addition, the metal elastic sheet 2 can be always abutted against the first antenna support 1 and the first flexible circuit board 3, and the effective connection between the first antenna support 1 and the first flexible circuit board 3 can be still ensured even when the first antenna support 1 or the first flexible circuit board 3 deforms.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: this disclosure makes first antenna support 1 be connected with metal casing 4 through first flexible circuit board 3, and then realizes ground connection. Compared with a printed circuit board with the thickness generally larger than 0.65 mm, the flexible printed circuit board (FPC) is thinner, and the total thickness of the flexible printed circuit board and the reinforcing plate is about 0.3 mm, so that the influence of the antenna on the thickness limit design of the terminal equipment can be reduced, and the thinner and thinner terminal equipment becomes possible.

In the related art, the flexible circuit is usually grounded by means of conductive adhesive bonding after copper leakage, however, the connection stability of the flexible circuit is poor due to the conductive adhesive bonding, and poor grounding is easily caused in the scheme of the first antenna bracket 1 grounded through the first flexible circuit board 3. In order to solve the technical problem, as shown in fig. 1 and 2, the terminal device antenna may further include a first fastening member 5 sequentially penetrating the first antenna support 1, the metal spring 2, the first flexible circuit board 3, and the metal housing 4. That is, the first antenna holder 1 is firmly locked to the first flexible circuit board 3 by the first fastening member 5, and the stability of the grounding of the first antenna holder 1 is improved.

Further, the metal dome 2 may be configured in a ring shape for circumferentially surrounding the first fastening member 5. Namely, the annular metal elastic sheet 2 can avoid the first fastening piece 5 which is arranged in a penetrating way. It should be understood that the annular shape here does not necessarily mean a closed circular ring, but may be a semi-closed ring configured in a C shape as long as it can avoid the first fastening member 5 passing therethrough.

To further save the Z-space of the antenna, as shown in fig. 1 and 2, the first antenna support 1 may be configured to be step-shaped, and includes a first connection section 11 and a second connection section 13 bent over the first connection section 11 by a bending section 12. Wherein, a space for accommodating the connector 6 is formed between the second connection section 13 and the first flexible circuit board 3, and the second connection section 13 is pressed above the connector 6 so as to maintain the stability of signal transmission of the connector 6.

The first antenna mount 1 is connected to the first flexible circuit board 3 by a first connection section 11. Alternatively, the first connecting section 11 may be provided with a hole through which the first fastening member 5 passes. In addition, in the embodiment in which the first antenna holder 1 is connected to the first flexible circuit board 3 by the first fastening member 5, the first connection section 11 is bent below the second connection section 13, and it is also possible to make the position of the first fastening member 5 after installation sunken with respect to the height of the second connection section 13, that is, to avoid adverse effects on the Z-direction space of the antenna due to the use of the first fastening member 5.

With continued reference to fig. 1 and 2, the terminal device antenna of the present disclosure may further include a second flexible circuit board 7 disposed at a distance from the first flexible circuit board 3, wherein the second flexible circuit board 7 is used for mounting the connector sub-base 61, the first flexible circuit board 3 is used for mounting the connector female base 62, and the connector sub-base 61 and the connector female base 62 are plugged and mated to transmit signals. The second connecting section 13 is pressed on the upper surface of the second flexible circuit board 3, so that the reliability of the inserting and matching of the connector 6 is ensured, and the stability of signal transmission is further ensured.

In some embodiments of the present disclosure, as shown in fig. 1 and 2, the terminal device antenna may further include a second antenna mount 8 disposed between the first flexible circuit board 3 and the metal case 4. The second antenna holder 8 may be configured in a zigzag shape including a first support section 81 and second support sections 82 extending from ends of the first support section 81 to both sides, respectively. Wherein the second supporting section 82 is used for abutting against the lower surface of the first flexible circuit board 3, and the first supporting section 81 is mounted on the metal shell 4 through the second fastener 10. Specifically, the flexible circuit board and the connector 6 are "clamped" on both sides in the Z direction by the first antenna mount 1 and the second antenna mount 8 to ensure efficient transmission of signals. In addition, the zigzag configuration of the second antenna mount 8 is more stable in structural strength, can provide a sufficient supporting effect, and has at least two supporting sections 82, further improving the strength of support.

The terminal device antenna may further comprise a printed circuit board 9, the printed circuit board 9 being arranged between the first flexible circuit board 3 and the metal housing 4. In order to further save the Z-direction space of the antenna, the printed circuit board 9 is provided with an avoidance groove 91 for avoiding the first support section 81. That is, the installed first support section 81 is received in the escape groove 91, so that the second fastening member 10 can also be sunk into the escape groove 91. Alternatively, referring to fig. 1 and 2, the metal case 4 is provided with a projection 41 upward in the Z direction so as to be in contact with the first flexible circuit board 3, and correspondingly, the printed circuit board 9 escapes from the projection 41 to be seated on the upper surface of the metal case 4.

In order to improve the antenna assembly efficiency and save the number of parts to be mounted, according to an embodiment of the present disclosure, the metal spring 2 may be welded on one side of the first flexible circuit board 3 facing the first antenna bracket 1. In addition, make metal shrapnel 2 and the integrative setting of first flexible circuit board 3 can also avoid metal shrapnel 2 unexpected drop or the drunkenness and influence signal transmission.
