Technical Field

[0001] This application relates to the technical field of rubber rod antennas, and particularly to a 4G full-frequency rubber rod antenna for electricity meter terminals. Background Art

[0002] The equipment of the wireless remote meter reading system transmits the data of on-site metering instruments and transmitters to the meter reading center through wireless communication, and the data is uniformly summarized and analyzed at the meter reading center to provide a basis for management and charging.

[0003] The data of the wireless remote meter reading system equipment needs to be centrally read and monitored through a rubber rod antenna. At present, the communication between systems mainly adopts 2G and TCP / TP network solutions. Therefore, the frequency of the rubber rod antenna of the wireless remote meter reading system equipment can only meet the 2G / 3G frequency band range. However, with the continuous popularization of the 4G communication network, the existing 2G / 3G frequency band range of the rubber rod antenna can no longer meet the customer's needs. Summary of the Invention

[0004] The embodiments of this application provide a 4G full-frequency rubber rod antenna for electricity meter terminals to solve the problem that 4G frequency band signals cannot be received in the related art.

[0005] In a first aspect, a 4G full-frequency rubber rod antenna for electricity meter terminals is provided, which includes:

[0006] A conductive core wire;

[0007] A copper tube, the copper tube is arranged around the conductive core wire and extends from one end of the conductive core wire to the other end;

[0008] A spring, the spring is conductively connected to the other end of the conductive core wire.

[0009] In some embodiments, the length of the spring is one-quarter wavelength of 700 - 960 MHz.

[0010] In some embodiments, the length of the copper tube is one-quarter wavelength of 1710 - 2700 MHz, and the length of the conductive core wire extending beyond the spring is one-quarter wavelength of 1710 - 2700 MHz.

[0011] In some embodiments, one end of the spring is provided with an extension portion that extends towards the direction of the copper tube.

[0012] In some embodiments, it further includes a heat shrinkable tube;

[0013] The heat shrinkable tube is wrapped on the extension portion.

[0016] In some embodiments, the connector is provided with a glue stick sleeve.

[0017] The conductive core wire, the copper tube, and the spring are arranged inside the glue stick sleeve, and the copper tube is closely arranged against the glue stick sleeve.

[0018] The embodiment of the present application provides a 4G full-frequency glue stick antenna for an electric meter terminal. Since the present application reasonably sets the lengths and positional relationships of the conductive core wire and the spring, the high-frequency signals corresponding to the 4G communication network are received and transmitted through the conductive core wire, and the low-frequency signals corresponding to the 2G / 3G communication network are received and transmitted through the spring.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0023] The embodiment of the present application provides a 4G full-frequency glue stick antenna for an electric meter terminal, which can solve the problem of not being able to receive 4G frequency band signals in the related art.

[0024] Please refer to Figure 1 , a 4G full-frequency glue stick antenna for an electric meter terminal, which includes:

[0025] Conductive core wire 1;

[0026] A copper tube 2 is arranged to surround the conductive core wire 1 and extends from one end of the conductive core wire 1 to the other end.

[0027] A spring 3 is conductively connected to the other end of the conductive core wire 1.

[0028] The conductive core wire 1 and the spring 3 with different lengths are designed according to different frequency band signals. In this application, the length of the conductive core wire 1 can be designed according to the requirements of the high frequency band, and the length of the spring 3 can be designed according to the requirements of the low frequency band, so as to enable this application to receive signals in the 2G / 3G / 4G frequency bands simultaneously.

[0029] It should be noted that the outside of the conductive core wire is wrapped with an insulating layer to ensure the safety and stability of signal transmission. The conductive connection between the conductive core wire 1 and the spring 3 is achieved by soldering, and the connection method is both firm and reliable.

[0030] The length of the spring 3 is one - quarter of the wavelength of 700 - 960 MHZ.

[0031] The length of the copper tube 2 is one - quarter of the wavelength of 1710 - 2700 MHZ, and the length that the conductive core wire 1 extends beyond the spring 3 is also one - quarter of the wavelength of 1710 - 2700 MHZ.

[0032] The length of the spring 3 is precisely calculated and set to be one - quarter of the wavelength of the low frequency 700 - 960 MHZ, so as to make the best use of the physical properties of the spring to achieve optimized reception in the low frequency band.

[0033] According to the electromagnetic wave transmission theory, when the length of a conductor is one - quarter of the wavelength of an electromagnetic wave propagating in the conductor, a relatively large voltage can be formed at the end of the conductor. Therefore, the copper tube 2 plays a role in improving the radiation efficiency and signal reception ability of the conductive core wire 1.

[0034] The length of the spring 3 is one - quarter of the wavelength of the low frequency 700 - 960 MHZ, and the length that the conductive core wire 4 extends beyond the spring 3 is also one - quarter of the wavelength of the high frequency 1710 - 2700 MHZ. The part of the conductive core wire 4 that extends beyond the spring 3 is responsible for the high frequency band range, that is, 1710 - 2700 MHZ, and the spring 3 and the part of the conductive core wire 4 surrounded by the spring 3 are responsible for the low frequency range, that is, 700 - 960 MHZ, forming a multi - segment frequency. By means of the spring 3 and the conductive core wire 4, the frequency coverage range of this application is broadened, so that the frequency range of the rubber rod antenna is within 700 - 960 / 1710 - 2700 MHz, and the voltage standing wave ratio VSWR is good, and the gain is relatively high, fully meeting the requirements of the wireless meter reading terminal for distance transmission.

[0035] One end of the spring 3 is provided with an extension part and a transmitting part, and the extension part extends towards the direction of the copper tube 2.

[0036] It also includes a heat - shrinkable tube 4.

[0037] The heat shrinkable tube 4 is wrapped around the extension part;

[0038] Since the extension part is close to the copper tube 2 and the heat shrinkable tube 4 wraps around the extension part, the extension part achieves an insulating effect.

[0039] It further includes a connector 5;

[0040] An inner conductor 6 is provided inside the connector 5. The inner conductor 6 is conductively connected to the end of the conductive core wire 1 away from the spring 3, and the copper tube 2 is connected to the connector 5;

[0041] Since the SMA (SubMiniature version A) interface is relatively common in practical applications, the connector 5 adopts an SMA interface. The connector 5 is installed on the wireless remote meter reading system device through the SMA interface, and signals are transmitted from the inner conductor 6 to the conductive core wire 1.

[0042] A rubber stick sleeve 7 is provided on the connector 5;

[0043] The conductive core wire 1, the copper tube 2, and the spring 3 are arranged inside the rubber stick sleeve 7, and the copper tube 2 is arranged close to the rubber stick sleeve 7;

[0044] The rubber stick sleeve 7 is detachably connected to the connector 5. The rubber stick sleeve 7 and the connector 5 can be connected by a threaded method. When the rubber stick sleeve 7 is installed on the connector 5, the rubber stick sleeve 7 functions to protect the components installed on the connector 5 and prevent the shortening of the service life due to the direct exposure of the components to the outside.
