Description

Technical Field

[0001] This utility model relates to wireless network communication equipment technology, specifically an antenna structure and an LTE module. Background Technology

[0002] The LTECat1 wireless communication module is designed specifically for M2M and IoT applications. It features comprehensive coverage of multiple network standards, rich functional interfaces, built-in GNSS (optional), support for Wi-FiScan positioning, and support for DFOTA.

[0003] For example, the publication (announcement) number: CN214256628U, publication (announcement) date: 2021-09-21, discloses an LTE CAT1 module, including a power module, a communication processing chip, an interface expansion module, a 2G signal circuit, a 4G signal circuit, and an antenna. The power supply terminal of the communication processing chip is electrically connected to the power module. The communication processing chip is also electrically connected to the interface expansion module, the 2G signal circuit, and the 4G signal circuit respectively. The 2G signal circuit is also electrically connected to the 4G signal circuit and the antenna respectively. The interface expansion module includes multiple GPIO interfaces and a hybrid interface, and each GPIO interface and the hybrid interface is electrically connected to the communication processing chip.

[0004] The shortcoming of existing technology is that, during the installation of traditional LTE module antennas, patch-shaped metal antennas are usually directly attached to the circuit board and soldered. However, the attached antenna will cause some functional surfaces to be lost due to the attachment, which will affect the signal transmission of the LTE module antenna. If a vertical patch-shaped antenna with stable installation and connection is provided, the functional surfaces of the antenna can be maximized. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 This utility model provides a technical solution, including the following embodiments:

[0027] Example 1

[0028] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment improves upon the original patch antenna by modifying the shape of the antenna itself and the connection point with the circuit board 1, allowing the antenna to be mounted vertically on the circuit board 1, i.e., the antenna body 2 with the end 3. The end 3 extends from the antenna body 2, and the connecting piece 31 abuts against the surface of the circuit board 1. The end 3 and the circuit board 1 are stably positioned by inserting the insert 32 and the socket 12. The end piece 34 abuts against the back of the circuit board 1, securing the end 3 firmly onto the circuit board 1, ensuring the stability of the antenna body 2 and the circuit board 1 after installation. Finally, soldering is used to strengthen the connection between the end 3 and the circuit board 1, allowing the antenna body 2 to stand firmly on the circuit board 1 and operate, thereby maximizing the signal transmission function of the antenna body 2.

[0029] Specifically, the end cap 3 is integrally formed on the antenna body 2, and the sheet-like structures on the end cap 3 are all integrally cut, which can ensure the structural strength of the end cap 3 and make the end cap 3 stably responsible for the installation of the antenna body 2.

[0030] Furthermore, a communicator 11 is fixedly mounted on the surface of circuit board 1. Its mounting method and communication method are existing technologies and will not be described in detail here.

[0031] Furthermore, the connecting piece 31 is obtained by vertically bending a strip extending from the antenna body 2 so that the insert 32 can be vertically inserted into the socket 12.

[0032] Example 2

[0033] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment details the locking function of the end piece 3. Before inserting the insert 32, the end piece 34 is inserted through the two oblique holes 13. The spacing between the two diagonally distributed oblique holes 13 is such that the width of the end piece 34 is greater than the width of the insert 32. Therefore, when the end piece 34 is inserted into the back of the circuit board 1 through the two oblique holes 13, the end piece 3 is rotated so that the end of the end piece 34 abuts against the back of the circuit board 1, thereby securing the circuit board 1 with the connecting piece 31 and the end piece 34.

[0034] Secondly, after rotating the end 3, the insert 32 moves from the diagonal position of the socket 12 to the position where it abuts against the side wall of the socket 12. The friction generated by the sliding contact between the arc-shaped side opening 33 and the inner wall of the socket 12 makes the insert 32 firmly fixed in the socket 12, thereby strengthening the connection between the end 3 and the circuit board 1.

[0035] Specifically, the antenna body 2 can be fitted with one or more end caps 3 depending on its size. If there is more than one end cap 3, it needs to be twisted individually using a tool, and the end cap 3 insert 32 will deform and twist to meet the locking function required by the end cap 3. When using a single end cap 3, the antenna body 2 can be rotated around the end cap 3, and the rotated antenna body 2 will stop at the designated position on the circuit board 1.

[0036] Example 3

[0037] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment details the sealing of the channels required for the locking of end 3 and the enhanced connection function. By bending two sheet-like bodies 36 away from each other around the fork 35 as the center line, they open in a V-shape on the side, causing the two sheet-like bodies 36 to respectively seal the two diagonally distributed oblique holes 13. This results in two additional abutting components on the back of the circuit board 1, improving the connection function of end 3 (e.g., Figure 4 As shown, the dashed box represents the predetermined shape of the sheet-like body 36 after it has been bent and opened.

[0038] Secondly, soldering is performed on the sheet 36 and the oblique hole 13 to further strengthen the support position of the sheet 36 and repair the oblique hole 13, thereby enhancing the stability of the circuit board 1.

[0039] Specifically, the two sheet-like bodies 36 are obtained from the end piece 34, which enables the two sheet-like bodies 36 to have a stable structural use capability, and the fork 35 makes the sheet-like bodies 36 easier to bend.

[0040] Furthermore, the two sheet-like bodies 36 can also be bent in the same direction, which can enable a single end 3 to have a larger end piece 34 for securing contact when multiple ends 3 are installed.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
