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.

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.

This is not limited in this specification.
Referring to FIG. 1 and FIG. 5, an embodiment of a separated communications device according to an embodiment of the present invention includes:
a body 1 and a movable connector 2;
the body includes an antenna 11 and a first conductive strip 12, and the antenna 11 is electrically connected to the first conductive strip 12;
the movable connector 2 includes a second conductive strip 21;
the second conductive strip 21 is connected to the first conductive strip 12 when the body 1 is connected to the movable connector 2; and
a connection position 17 is set on the body 1, where when the movable connector 2 is connected to the body 1, the connection position 17 refers to a part, covered by the movable connector 2 due to the connection, on a surface of the body 1, and the antenna 11 is disposed on the body 1 near the connection position 17.
In this embodiment of the present invention, an antenna 11 on a body 1 near a connection position 17 is electrically connected to a first conductive strip 12, so that the first conductive strip 12 serves as a part of the antenna 11 and signal strength of the antenna is enhanced. In addition, when the body 1 is connected to a movable connector 2, a second conductive strip 21 on the movable connector 2 is electrically connected to the first conductive strip 12, so that the second conductive strip 21 further serves as an extended part of the antenna 11. Therefore, signal strength of the extended antenna 11 is 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 to FIG. 1 to FIG. 8, another embodiment of a separated communications device according to an embodiment of the present invention includes:
a body 1 and a movable connector 2;

the movable connector 2 includes a second conductive strip 21;
the second conductive strip 21 is connected to the first conductive strip 12 when the body 1 is connected to the movable connector 2; and
a connection position 17 is set on the body 1, where when the movable connector 2 is connected to the body 1, the connection position 17 refers to a part, covered by the movable connector 2 due to the connection, on a surface of the body 1, and the antenna 11 is disposed on the body 1 near the connection position 17. Another connection position 26 corresponding to the connection position 17 is set on the movable connector 2.
Correspondingly, when the movable connector 2 is connected to the body 1, the another connection position 26 refers to a part, covered by the body 1 due to the connection, on a surface of the movable connector 2. It may be understood that the connection position 17 and the another connection position 26 are two opposite parts. Optionally, the connection position 17 or the another connection position 26 includes an insulation part and/or a conductive part.

It should be noted that, that the second conductive strip 21 is electrically connected to the first conductive strip 12 means that, when the body 1 is connected to the movable connector 2, the second conductive strip 21 and the first conductive strip 12 are directly connected; because both the first conductive strip 12 and the second conductive strip 21 are conductive materials, when the second conductive strip 21 and the first conductive strip 12 are directly connected, a carrier can flow freely between the second conductive strip 21 and the first conductive strip 12 to produce a current.
It should be noted that, that the antenna 11 is electrically connected to the first conductive strip 12 means that the antenna 11 and the first conductive strip 12 may affect each other in a direct connection manner or an indirect coupling manner. In the indirect coupling manner, a gap may exist between the antenna 11 and the first conductive strip 12, and the antenna 11 may be coupled to the first conductive strip 12 by using the gap.

Alternatively,
