Fig. 4 is a diagram of an application scenario in which an electronic device transmits and receives wireless signals by using an antenna. In this figure, the overall application scenario is a network environment 100 consisting of an electronic device 102A, an electronic device 102b, a wifi access point 104, a cellular base station 105, and a network 106 of core networks. The electronic device 102A and the electronic device 102B stop the WIFI connection when receiving the instruction to perform wireless transmission using the cellular circuit, and resume the WIFI connection when receiving the instruction to stop performing wireless transmission using the cellular circuit.

In this process, if the antenna signal is shielded by the metalwork that sets up on the electronic equipment casing, just unable quick receiving and dispatching radio signal to be unfavorable for carrying out fast switch over between the radio signal that honeycomb circuit sent and WIFI radio signal fast, be unfavorable for user experience's promotion.

In the embodiment of the present disclosure, the structure of the connection of the multiple layers of metal parts is utilized to ground the multiple layers of metal parts, so that the shielding can be reduced, and the poor transmission and reception of the wireless signals can be reduced.

Here, it should be noted that the rear cover may be a conductive member (e.g., a metal member) or an insulating member (e.g., a plastic member), and is not limited herein.

Different electric connection modes can be provided for the rear covers made of different materials, so that all metal pieces arranged on the rear covers are grounded, and the shielding is reduced.

For example, in the case that the rear cover is a metal member, the first conductive member 14 may be electrically connected to the rear cover, and the second metal member 13 may be electrically connected to the rear cover by means of an electrically conductive adhesive, a contact and/or an electrically conductive screw connection.

sixth apertures

151 and 161.

In these embodiments, the third metal member 15, the first adhesive layer 16, and the second conductive member 17 are provided, and the third metal member 15 and the second metal member 12 are electrically connected by the second conductive member 17. On the one hand, the second metal piece 13 and the third metal piece 15 can form a multilayer camera decoration piece, so that the aesthetic degree of the camera decoration piece can be improved, and the camera assembly can be better protected. On the other hand, the third metal part 15 can be electrically connected to the grounding point through the second conductive member 17, which also reduces the shielding of the antenna signal by the third metal part 15.

In some embodiments, the first conductive member 14 and the second conductive member 17 may be both conductive foam.

Thus, the multilayer metal piece can be electrically connected. And the conductive foam can form buffering between the first metal piece 12 and the second metal piece 13, and between the second metal piece 13 and the third metal piece 15, so as to solve the problems of mechanical connection and electrical connection between the multiple layers of metal pieces in the related art. By utilizing the high elasticity of the conductive foam, the first metal part 12 and the second metal part 13 can be well electrically connected.

The number of the first conductive member 14 and the second conductive member 17 is not particularly limited. In practical application, the areas and the numbers of the first conductive members 14 and the second conductive members 17 can be set reasonably according to the areas of the metal members, so as to realize the electrical connection between the multiple layers of metal members.

In this example, the first conductive member 14 is disposed in the second opening 112 of the insulating member 11, and the second conductive member 17 is disposed in the sixth opening 161 of the first adhesive layer 16.

In some embodiments, the second aperture 112 and the sixth aperture 161 are staggered in a direction gradually away from the image capturing module. Thus, the first metal part 12 and the second metal part 13, and the second metal part 13 and the third metal part 15 can be electrically connected at different positions, and under the condition that the first conductive part 14 and the second conductive part 17 are both conductive foam, the first metal part 12, the second metal part 13 and the third metal part 15 can be stably connected at different positions and have flatness at different positions.

Some embodiments of the present disclosure provide a rear cover applied to an electronic device. The rear cover may include: a back cover body and the protection module. The second metal piece in the protection module is arranged on the outer side of the rear cover body, and the insulating piece and the first metal piece are arranged on the inner side of the rear cover body. The part of the image acquisition module and the first conductive piece also penetrate through the rear cover body, and the first conductive piece is also electrically connected with the second metal piece.

The electronic equipment can be any electronic equipment with an image acquisition module. Such as a personal computer, a mobile phone, a computer, a digital video camera, a digital broadcasting terminal, a medical device or a fitness device, etc.

In the above description, only an example that the rear cover body is an insulating member is shown, and it can be understood by those skilled in the art that, in the case that the rear cover body is a metal member, the rear cover body may also be electrically connected to the grounding point through electrical connection, so as to reduce shielding of the rear cover body on an antenna signal.

In the present invention, when the rear cover is assembled, the insulating member 11, the first metal member 12, the rear cover body, the second metal member 13, and the third metal member 15 are sequentially arranged according to the sequence of the first metal member 12, the insulating member 11, the rear cover body, the second metal member 13, and the third metal member 15 along the direction gradually away from the image capturing module, so that the portion of the image capturing module sequentially penetrates through the third opening, the first opening, the fourth opening, the fifth opening, and the sixth opening along the direction gradually away from the image capturing module. Thus, the first metal part 12 and the insulating part 11 can be fixed by buckling the rear cover body and the front shell.

Of course, in some embodiments, in order to improve the fixing firmness of the first metal part 12 and the insulating part 11, since the first metal part 12 is mounted on the insulating part 11, before assembling, the insulating part 11 may be connected to the rear cover body by means of double-sided tape adhesion and/or screw fixation, so that the first metal part 12 can also be fixed.

In some embodiments, as shown in fig. 1, the rear cover further comprises: and a second adhesive layer 18 disposed between the insulating member 11 and the rear cover body. The second adhesive layer 18 is provided with a seventh opening 181 and an eighth opening 182, the seventh opening 181 is aligned with the first opening 111, and the eighth opening 182 is used for the first conductive member 14 to pass through.

In these embodiments, by providing the second adhesive layer 18, the insulating member 11 and the rear cover body can be adhered and fixed to each other, the insulating member 11 and the first metal member are prevented from being displaced inside the electronic device, and the assembly efficiency can be improved. Meanwhile, the seventh opening 181 is formed in the second adhesive layer 18, so that the image acquisition module can pass through the second adhesive layer, and the image acquisition module is communicated with the inside and the outside of the rear cover body. By providing the eighth opening 182 on the second adhesive layer 18, it is ensured that the first conductive member passes through the second adhesive layer 18 and the rear cover body to be electrically connected with the second metal member 13.

Here, it should be noted that, since the arrangement of the metal member easily shields the antenna signal, the shielding is reduced by arranging the first metal member inside the electronic device to ground the second metal member and/or the third metal member. In this process, if the area of the first metal part is too large, the shielding effect is not favorable. If the area of the first metal part is too small, the first metal part is not favorable for fixing inside the electronic device.

In the embodiment of the present disclosure, in view of the above, the insulating member 11 is adopted to fix the first metal member 12, so that the first metal member 12 can be set to be smaller as long as it can be electrically connected with the second metal member 13 and/or the third metal member 15, and the first metal member 12 can be firmly fixed by connecting the insulating member 11 with a larger area to the inside of the electronic device.

For the problem that the first metal part 12 is electrically connected with the second metal part 13 and/or the third metal part 15, because the first metal part 12 is disposed inside the electronic device, and the second metal part 13 and/or the third metal part 15 is disposed outside the electronic device, the first metal part 12 can be electrically connected to the second metal part 13 and/or the third metal part 15 by using the conductive foam in a manner of drilling holes on the rear cover body. The problem of mechanical connection and electric connection between the multilayer metalwork is solved ingeniously, can prevent to produce the influence to antenna signal under the pleasing to the eye condition of realization metal decoration, promote user experience.
