The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The invention is described in further detail below with reference to the attached drawing figures:

in order to make up the problem that the performance of the existing antenna does not affect the appearance, a universal clamp of the police terminal is just utilized, and a group of antennas are arranged on the universal clamp to make up the problem that the antennas on part of the police terminal are poor.

Therefore, as shown in fig. 1, the invention provides an optimizing device of an external antenna of a police terminal, which comprises a police terminal 10 and a universal clamp 20; which is an improvement over the existing police terminal 10 and universal clip 20.

Wherein:

the existing police terminal 10 comprises a slot 11 and a slot 12, wherein an internal antenna of 4-5 antennas (2/3/4G main antenna, 2/3/4G diversity antenna, wifi & BT antenna, GPS antenna and private network antenna) is arranged in the police terminal, an external antenna of 4-5 antennas is arranged outside the police terminal, and the external antenna is connected with the internal antenna to form a complete 4-5 antenna structure. The existing universal clamp 20 comprises a plug 21 and a clamping head 22, when the universal clamp 20 is installed, the plug 21 of the universal clamp 20 is inserted into the slot 11 of the police terminal 10, and after the plug is inserted in place, the clamping head 22 of the universal clamp 20 is just clamped in the clamping slot of the police terminal 10, so that the police terminal 10 and the universal clamp 20 are fixed and then hung in front of the chest of a police worker; in normal use, the police terminal 10 and the universal clamp 20 are fixed together without being detached.

On the basis of the existing police terminal and universal clamp, the improvement is as follows:

according to the practical use condition of 4-5 antennas, the invention sets the external antenna with poor use experience on the universal clamp 20, which is caused by the poor environment, poor parameters, no network search under weak signals or unstable network; fig. 1 shows that an external antenna 23 (which may be a GPS antenna or an external network antenna) is disposed on the gimbal clamp, and the internal antennas of all antennas and the remaining external antennas are designed in corresponding positions and maintain the connection of the existing internal and external antennas without modification. Meanwhile, besides the arrangement of one external antenna on the universal clamp 20 shown in fig. 1, one or more other external antennas can be arranged on the universal clamp; the principle is as follows.

The present invention takes the GPS external antenna 23 as an example, and the setting principle is explained as follows:

because the GPS external antenna 23 is arranged on the universal clamp, how to realize the connection between the GPS external antenna 23 and the existing GPS internal antenna in the police terminal needs to be considered; therefore, the external antenna and the contactor of the internal antenna need to be designed to realize the connection of the internal antenna and the external antenna; therefore, the universal clamp 20 is provided with a contact point 24 connected with a GPS external antenna 23, and the police terminal 10 is provided with a contact 13; because the police terminal 10 and the universal clip 20 are buckled at the slot 11 and the plug 21, the bottom of the slot 11 is further provided with the contact 13, and the plug 21 is provided with the contact point 24 corresponding to the contact 13; when the plug 21 of the universal clamp 20 is snapped into the slot 11 of the police terminal 10, the contact 13 is just in contact with the contact point 24, so that the GPS external antenna 23 on the universal clamp 20 can be connected with the GPS internal antenna in the police terminal 10.

Furthermore, the contactor capable of realizing the above functions can be an existing conventional pogo pin contactor or cable wire contactor, and the pogo pin contactor or the cable wire contactor are both of conventional contactor structures, so the structure and the principle thereof are not elaborated herein.

Further, the above-mentioned connection mode that shows an external antenna, if be equipped with two external antennas on the universal clamp, then correspond set up 2 contacts and contact point can, the position that specifically sets up centers on plug and slot, finally guarantees just after the plug inserts the slot that the contact is connected with the contact point.

Further, the external antenna is directly attached to the universal clip 20.

Further, the external antenna is an omnidirectional antenna, a PIFA antenna or an LVDS antenna.

The invention also provides an optimization method based on the optimization device, which comprises the following steps:

judging whether the contact is contacted with the contact point;

Wherein,

the invention is composed of an external antenna circuit (the existing antenna) on the police terminal and an antenna on the universal clamp, and the external antenna circuit and the antenna form an external antenna whole. When the universal clamp is buckled, the elastic needle (or cable line contact mode) on the terminal contacts the antenna on the universal clamp, and the switching circuit on the board can automatically switch the antenna from the internal antenna to the external antenna. Because there are a plurality of faces to do the antenna on the universal clamp, so antenna environment is superior, keeps away from the intelligent terminal body again, has reduced the interference, and the antenna performance can accomplish the optimum.

The invention has the advantages that:

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
