Detailed Description

The present invention is further illustrated by way of example and not by way of limitation in the scope of the following examples in connection with the accompanying drawings.

As shown in fig. 1 to 5, the fixing device 100 of the BTB connector includes: a bracket 110 and a cover 120.

The bracket 110 is provided with a connecting opening 113 and a grounding abutting part 112, the cover 120 detachably covers the bracket 110, and a grounding contact 121 is arranged on the cover 120 corresponding to the grounding abutting part 112.

The fixing device 100 fixes the BTB connector and simultaneously grounds the BTB connector by providing the ground contact 121 on the cover 120, thereby avoiding cost increase caused by additional adhesion of a conductive material. The mobile terminal can reduce the manufacturing cost by adopting the fixing device 100.

The bracket 110 is used to house the female end 132 of the BTB connector. The bracket 110 is provided with a recess 111, and the grounding abutting portion 112 is a bottom surface of the recess 111.

The recess 111 may provide a limit for an FPC (flexible Printed circuit) flexible board of the BTB connector, and the FPC flexible board 133 may be easily placed in the recess 111.

As shown in fig. 5, the ground abutting part 112 protrudes toward the cover 120 to be closer to the ground contact 121 of the cover 120 to better contact with the ground contact 121. However, the present invention is not limited to this, and the ground abutting portion 112 may be a simple plane.

The connection opening 113 is adjacent to the ground abutting portion 112.

As shown in fig. 6 to 8, the connection opening 113 of the bracket 110 is used to expose the female end 132 of the BTB connector, the male end 131 of the BTB connector is connected with the female end 132, and the FPC flexible board 133 connected with the male end 131 is placed on the ground abutting portion 112. When the cover 120 covers the holder 110, the ground contact 121 abuts against the FPC flexible board 133, thereby grounding the FPC flexible board 133 to ground the BTB connector.

In fig. 6, the male end 131 is not connected to the female end 132, and the cover 120 is suspended above the bracket 110. In fig. 7, the male end 131 is connected to the female end 132, and the cover 120 is suspended above the bracket 110. In fig. 8, the cover 120 is shown covering the bracket 110.

Fig. 6-8 sequentially show the connection process of the BTB connector to the PCB board 140.

As shown in fig. 4, the ground contact 121 is an elastic contact. The elastic contact may automatically adjust the pressure applied to the ground abutting portion 112, thereby ensuring that the ground contact 121 is in contact with the FPC flexible board 133.

In the present embodiment, the ground contact 121 is a point on the spring 122.

The invention is not limited in this regard and the ground contact 121 may be a point disposed directly on the cover 120 or other electrically conductive structure.

One end of the elastic sheet 122 is integrally connected to the bracket 110, and the other end of the elastic sheet 122 is a free end. The other end of the spring 122 forms an arc or a curved surface recessed toward the opposite side of the cover 120, and the bottom end of the arc or the curved surface is the ground contact 121. The ground contact 121 need not be a single and discrete point, but may be a line of continuous points, or a surface of continuous points. When the ground contact 121 is a line, the elastic piece 122 is in line contact with the FPC flexible printed circuit 133, and when the ground contact 121 is a surface, the elastic piece 122 is in surface contact with the FPC flexible printed circuit 133.

The ground contact 121 is a projecting portion that projects toward the ground abutting portion.

Alternatively, the ground contact 121 may not be an elastic contact but may be only a projection that performs press-contact with the FPC flexible board 133 when contacting the FPC flexible board 133. The protrusion can also achieve the same point contact, line contact, and surface contact as the spring 122.

The cover 120 is a shield. In this way, the cover 120 may provide electromagnetic shielding for the BTB connector, placing electromagnetic interference of the BTB connector with components on other boards.

The present embodiment further provides a mobile terminal, which includes: such as the above BTB connector securing device 100.

The mobile terminal further includes: the flexible printed circuit board (FPC) 133, the Printed Circuit Board (PCB) 140 and the BTB connector, wherein the FPC 133 is connected to the male end 131 of the BTB connector, the female end 132 of the BTB connector is arranged on the PCB 140, the bracket 110 is fixed on the PCB 140 and covers the female end 132, the female end 132 is exposed out of the connecting opening 113, the male end 131 is connected to the female end 132, and the grounding contact 121 enables the FPC 133 to be abutted to the grounding abutting portion.

The cover 120 is a shield can on the PCB board 140. The BTB connector is fixed and grounded by the shielding case of the PCB, so that the cost is saved and the arrangement is more convenient.

In the present embodiment, a BTB connector is used to connect the camera 150 to the PCB board 140. However, the invention is not limited thereto, and the BTB connector can also be connected with other various modules in the mobile terminal to realize the connection of the modules and the PCB board.
