Technical Field

The utility model belongs to the technical field of communication equipment, concretely relates to electronic equipment.

Background

At present, in order to make a mobile phone light and thin, a middle frame of the mobile phone is perforated at the position of a camera with larger thickness in the market. Thus, the camera support has to be used to position the camera.

At present, camera supports are mainly divided into two types: metal camera support and plastic camera support.

The metal camera support is mainly realized by an alloy die-casting mode at present. The alloy camera support mainly has two disadvantages: firstly, the cost is high; second, the weight is heavier for the plastic camera support.

The plastic camera bracket has more advantages in cost and has certain benefits for reducing the weight of the whole camera.

However, the existing plastic camera support does not have a completely reliable method for grounding the camera, and most of the existing plastic camera support depends on auxiliary materials and a metal middle frame for grounding, and conductive sponge, copper foil, conductive cloth and the like are common.

When adopting electrically conductive sponge ground connection mode, electrically conductive sponge often will pass through the bottom of camera, can directly exert certain pressure to the bottom of camera like this, and the reliability risk appears easily in this mode ground connection to the camera that the part is more sensitive to pressure, therefore electrically conductive sponge's use mode is limited easily.

When the grounding mode of the conductive cloth or the copper foil is adopted, the conductive cloth and the copper foil are adhered to the metal bottom surface of the camera through the conductive adhesive, and if the conductive adhesive is not adhered in place, the condition that the contact resistance is unstable can occur; in addition, the bottom of part of the camera is not in a metal completely exposed state but leaks copper, and the bottom of the camera is not completely flat, so that the condition that the resistance is higher due to the fact that the conductive cloth and the copper foil cannot be pasted to the ground easily occurs, and the grounding stability is not facilitated.

In addition, when the grounding mode of the conductive cloth or the conductive copper foil is adopted, the camera is often required to be adhered to the upper cover of the circuit board, the disassembly difficulty of the camera is increased, the FPC of the rear camera is easily broken when the camera is forcibly disassembled, and the disassembly and maintenance are not facilitated.

In addition, with the volume and the thickness of part of cameras becoming bigger and bigger, the situation that the camera is broken to avoid is often appeared, the difficulty that the auxiliary material is used for grounding the camera under the situation is bigger, and the grounding reliability is worse.

After the 5G era comes, the performance requirement of the antenna on grounding will be higher and higher, which requires that the grounding mode of the camera needs to be considered and optimized.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application aims to provide electronic equipment which can solve the problem that the existing camera module is poor in grounding stability.

In order to solve the technical problem, the present application is implemented as follows:

an embodiment of the present application provides an electronic device, including: a camera module; the circuit board is arranged on one side of the camera module; the elastic sheet is provided with a first elastic arm and a second elastic arm which are perpendicular to each other, the first elastic arm abuts against a copper leakage area of the circuit board, the second elastic arm abuts against the camera module, and the camera module is electrically connected with the circuit board through the elastic sheet.

In this application embodiment, through set up the shell fragment between camera module and circuit board, realize the direct ground connection between camera module and the circuit board, avoided among the prior art between camera module and circuit board because of adopt the resistance that electrically conductive cloth or copper foil lead to higher, because of scribbling the circumstances such as the conducting resin and be not convenient for dismantle.

As shown in fig. 2, a conductive adhesive is applied between the camera 1 and the circuit board upper cover 3, and then a conductive cloth or copper foil 4 is provided between the camera 1 and the circuit board upper cover 3. Under the conditions that the conductive adhesive is not adhered in place, copper leaks from the bottom of the camera and the like, the condition that the resistance is high due to the fact that the conductive cloth and the copper foil are not adhered in place easily occurs.
