BACKGROUND

With rapid development of a smartphone, functions of the smartphone change quickly. Some detachable function modules, such as a detachable battery module, a detachable photographing module, and other auxiliary function modules, are increasingly widely applied to the smartphone. However, a communication function is still one of the most significant functions of the smartphone. Generally, these auxiliary function modules installed on the smartphone not only bring more functions, but also interfere with communication of the phone, decreasing communication quality of the phone.

In the prior art, the detachable module is usually located at the top of the phone and is mostly made of metallic materials. When the detachable module is added, a top antenna near the detachable module is blocked by the detachable module. Consequently, sensitivity of the top antenna decreases by 6 to 7 decibels, and the phone on which the detachable module is installed has poor communication quality in communication with the outside or even cannot communicate with the outside normally.

With reference to the first aspect and the first implementation manner of the first aspect, in a fourth implementation manner of the first aspect of the present invention, a communications slot and stopper grooves are disposed in the connection position; a communications plug matching the communications slot and stopper protrusions matching the stopper grooves are disposed in the another connection position; the body is fixedly connected to the movable connector when the stopper grooves are engaged with the stopper protrusions; and the first conductive strip is connected to the second conductive strip when the communications slot is electrically connected to the communications plug.

With reference to the first aspect and the fourth implementation manner of the first aspect, in a fifth implementation manner of the first aspect of the present invention, the stopper protrusions are symmetrically disposed on two sides of the communications plug; and the stopper grooves are symmetrically disposed on two sides of the communications slot.

It can be seen from the foregoing technical solution that, in the embodiments of the present invention, an antenna on a body near a connection position is electrically connected to a first conductive strip, so that the first conductive strip serves as a part of the antenna and signal strength of the antenna is enhanced. In addition, when the body is connected to a movable connector, a second conductive strip on the movable connector is electrically connected to the first conductive strip, so that the second conductive strip further serves as an extended part of the antenna.

It should be noted that, a movable connector2in this specification is a detachable function module, which can specifically be another extended function module such as a camera or a secondary battery. This is not limited in this specification. In addition, materials and shapes of a first conductive strip12and a second conductive strip12in this specification are not limitedly described. The material may be any one of a conductor material, a semi-conductor material, or a superconductor material, or may be a conductor material obtained by combining at least any two of the three. A specific combination ratio or density or the like is not limitedly described, provided that a conductive function works. For example, the first conductive strip11may be a closed or half closed metal frame, and the second conductive body12may be a closed or half closed metal frame. This is not limited in this specification.

Referring toFIG. 1andFIG. 5, an embodiment of a separated communications device according to an embodiment of the present invention includes:

a body1and a movable connector2;

the body includes an antenna11and a first conductive strip12, and the antenna11is electrically connected to the first conductive strip12;

the movable connector2includes a second conductive strip21;

the second conductive strip21is connected to the first conductive strip12when the body1is connected to the movable connector2; and

a connection position17is set on the body1, where when the movable connector2is connected to the body1, the connection position17refers to a part, covered by the movable connector2due to the connection, on a surface of the body1, and the antenna11is disposed on the body1near the connection position17.

In this embodiment of the present invention, an antenna11on a body1near a connection position17is electrically connected to a first conductive strip12, so that the first conductive strip12serves as a part of the antenna11and signal strength of the antenna is enhanced. In addition, when the body1is connected to a movable connector2, a second conductive strip21on the movable connector2is electrically connected to the first conductive strip12, so that the second conductive strip21further serves as an extended part of the antenna11. Therefore, signal strength of the extended antenna11is further significantly enhanced, communication quality in communication between a communications terminal and the outside is effectively improved, and a problem in the prior art that, when a detachable module is installed on a phone, a communication function of the phone deteriorates and the phone cannot communication with the outside is resolved.

Referring toFIG. 1toFIG. 8, another embodiment of a separated communications device according to an embodiment of the present invention includes:

a body1and a movable connector2;

the body includes an antenna11and a first conductive strip12, and the antenna11is electrically connected to the first conductive strip12;

the movable connector2includes a second conductive strip21;

the second conductive strip21is connected to the first conductive strip12when the body1is connected to the movable connector2; and

a connection position17is set on the body1, where when the movable connector2is connected to the body1, the connection position17refers to a part, covered by the movable connector2due to the connection, on a surface of the body1, and the antenna11is disposed on the body1near the connection position17. Another connection position26corresponding to the connection position17is set on the movable connector2.

Correspondingly, when the movable connector2is connected to the body1, the another connection position26refers to a part, covered by the body1due to the connection, on a surface of the movable connector2. It may be understood that the connection position17and the another connection position26are two opposite parts. Optionally, the connection position17or the another connection position26includes an insulation part and/or a conductive part.

For example, a shape of the body1is similar to a cuboid that includes two opposite long sides and two opposite short sides and has a particular thickness. One of the short sides is the connection position17, and the antenna11is near the short side. Optionally, the first conductive strip12is also near the short side, or the first conductive strip12is disposed on the short side, or the short side is the first conductive strip12.

It should be noted that, that the antenna11is electrically connected to the first conductive strip12means that the antenna11and the first conductive strip12may affect each other in a direct connection manner or an indirect coupling manner. In the indirect coupling manner, a gap may exist between the antenna11and the first conductive strip12, and the antenna11may be coupled to the first conductive strip12by using the gap.
