[0030] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0031] An embodiment of the utility model provides a wireless network module, including a network card and antenna integrated module and a connection module; the network card unit and the antenna unit in the network card and antenna integrated module are integrated on the same circuit board, which effectively reduces the distance of analog signal transmission between the two, and the network card and antenna integrated module is connected to the mainboard of the electronic product through a connector. Compared with the original design in which the network card unit is set on the mainboard, the volume of the connector is smaller than the volume of the network card unit, thereby reducing the space required for the mainboard and the components on the mainboard.

[0032] The following is a detailed description of the various modules of the wireless network module provided by the embodiment of the present utility model, as well as the connection relationship and position relationship of each module in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, the network card and antenna integrated module 10 includes a circuit board 11, a network card unit 12 and an antenna unit 13, and the network card unit 12 and the antenna unit 13 are arranged on the circuit board 11; wherein, a metal line is provided on the circuit board 11, and the network card unit 12 and the antenna unit 13 are connected through the metal line of the circuit board. Compared with the existing design, the distance between the network card unit 12 and the antenna unit 13 is closer, and there is no need for a long wire harness to transmit the analog signal, thereby effectively reducing the loss of the analog signal.

[0034] For example, the network card unit 12 and the antenna unit 13 are integrated, which can reduce the loss of the network card unit 12 and the antenna unit 13 by about 2dB and reduce the partial loss of the internal switch insertion loss of the network card unit 12 by about 1dB, that is, the high-frequency signal can improve the RF link performance by about 3dB in total, which can improve the high-frequency signal transmission rate and increase the transmission distance.

[0035] In the embodiment of the utility model, the antenna unit 13 includes a main antenna module 131 and an auxiliary antenna module 132. The main antenna module 131 and the auxiliary antenna module 132 are arranged on the circuit board 11 and are respectively connected to the chip of the network card unit 12. For example, the chip of the network card unit 12 is an SCM2625A chip. For example, the cross-sectional shape of the circuit board 11 is rectangular, and the main antenna module 131, the network card unit 12 and the auxiliary antenna module 132 are arranged on the circuit board 11 in sequence along the length direction of the circuit board 11.

[0036] In the embodiment of the utility model, in the network card and antenna integrated module 10, the network card unit 12 and the antenna unit 13 are structurally integrated on the same circuit board 11, and the network card unit 12 and the antenna unit 13 themselves are not changed.

[0037] In an embodiment of the utility model, the network card and antenna integrated module 10 is connected to the motherboard 30 of the electronic product through a connection module 20, wherein the connection module 20 includes a first connector 21, a second connector 22 and a wiring harness 23, the first connector 21 and the second connector 22 are connected through the wiring harness 23, the first connector 21 is arranged on the circuit board 11, and the second connector 22 is used to be arranged on the motherboard 30 of the electronic product, and the volume of the second connector 22 is smaller than the volume of the network card unit 12.

[0038] First, between the first connector 21 and the second connector 22, the wire harness 23 transmits a digital signal. If a loss of the digital signal occurs, signal compensation can be performed. The signal compensation method is to correct and compensate the signal by means of preprocessing, feedback adjustment, adaptive adjustment, digital signal processing or error correction, so as to improve the transmission quality and reliability of the signal. In the embodiment of the utility model, the signal compensation scheme is not limited.

[0039] Secondly, the first connector 21 is arranged on the circuit board 11, and the second connector 22 is arranged on the main board 30. Compared with the prior art, the electronic product realizes the wireless network function, and the second connector 22 in the wireless network module is arranged on the main board 30 of the electronic product; and the volume of the second connector 22 is smaller than the volume of the original network card unit 12, thereby reducing the space occupied by the wireless network module on the circuit board 11; that is, the main board 30 structure occupies a smaller space in the electronic product, which is conducive to the miniaturization design of the electronic product. For example, the size of the original network card unit 12 is 30 mm × 22 mm, while the size of the second connector 22 is 10 mm × 3 mm.

[0040] For example, in the embodiment of the utility model, the length range of the circuit board 11 is 50 mm to 60 mm, and the width range of the circuit board 11 is 5 mm to 15 mm. Taking the example of the length of the circuit board 11 being 55 mm and the width being 10 mm, the length of the main antenna module 131 is 20 mm, the length of the network card unit 12 is 15 mm, and the length of the auxiliary antenna module 132 is 20 mm.

[0041] In the embodiment of the utility model, the shapes and size ranges of the circuit board 11, the network card unit 12 and the antenna unit 13 are not limited thereto, and their shapes and sizes can be adaptively designed according to the size and shape of the electronic product.

[0042] like Figure 2As shown in FIG5 , the embodiment of the utility model further provides an electronic product, comprising the wireless network module and a mainboard 30, wherein the second connector 22 of the wireless network module is disposed on the mainboard 30. The mainboard 30 and the electronic components on the mainboard 30 in the electronic product occupy a certain space, and by optimizing the structure of the mainboard 30 and the space occupied by the electronic components on the mainboard 30, the space occupied by the mainboard 30 on the electronic product can be reduced.

[0043] In the embodiment of the utility model, a second connector 22 is used on the mainboard 30 to connect with the network card and antenna integrated module 10. The second connector 22 occupies a smaller space than the original network card unit 12, thereby reducing the space occupied by the mainboard 30, which is beneficial to the miniaturization design of electronic products.

[0044] Among them, regarding the setting position of the network card and antenna integrated module 10, it can be set at the position of the original antenna unit 13, or at other possible positions; the position or interface orientation of the first connector 21 and the second connector 22 can be designed according to the position of the network card and antenna integrated module 10 and / or the main board 30. For example, the interface of the first connector 21 on the circuit board 11 is set toward the main board 30 of the system end 2; the wire harness 23 between the first connector 21 and the second connector 22 is in a straight line state. The wire harness 23 is in a straight line state, and the wire harness 23 used is short. For example, the length of the wire harness 23 ranges from 200 mm to 300 mm, which can meet the signal transmission requirements and reduce signal loss.

[0045] For example, the electronic product includes a display terminal 1 and a system terminal 2; the wireless network module is disposed on the display terminal 1 or the system terminal 2, and the second connector 22 is disposed on a mainboard 30 of the system terminal 2. For example, the electronic product is a laptop computer.

[0046] like Figure 4a and Figure 4b As shown, for example, the network card and antenna integrated module 10 is disposed in the housing of the display terminal 1 and is located on a side away from the system terminal 2. Alternatively, Figure 5a and Figure 5b As shown, for example, the network card and antenna integrated module 10 is disposed in the housing of the system end 2 and is located on a side away from the display end 1. Wherein, whether the network card and antenna integrated module 10 is disposed at the display end 1 or at the system end 2, the network card and antenna integrated module 10 is disposed at a corner position of the housing of the display end 1 or the housing of the system end 2.

[0047] The link loss on the signal path includes: the internal wiring at the mainboard 30 end, the internal wiring at the network card end, and the coaxial wiring between the mainboard 30 and the network card end. The signal integrity simulation is used to smooth out the loss. The location of the network card and antenna integrated module 10 meets the design requirements, and the length of the wiring harness 23 does not exceed 400 mm, preferably, between 200 mm and 300 mm.

[0048] The utility model provides a wireless network module and an electronic product, in which a network card unit 12 and an antenna unit 13 are integrated on the same circuit board 11 to form an integrated module. When the module is connected to a mainboard 30, it only needs to be connected to a connector on the mainboard 30.

[0049] In the technical solution of the utility model, the network card and the antenna are integrated, the distance between the two is closer, the loss of analog signal transmission is low, and the digital signal is transmitted between the first connector 21 and the second connector 22 through the wiring harness 23, and the signal loss can be compensated, so that the signal transmission distance can be increased and the transmission rate can be improved, thereby achieving the purpose of increasing the signal strength; among which, the transmission distance can be increased by about 25%, which can basically solve the problems of poor signal and poor wall penetration performance that affect the customer experience; the average data transmission is increased by 34%, and the average data reception is increased by 27%;

[0050] In addition, the network card is not arranged on the motherboard 30 of the electronic product, and does not occupy the space of the motherboard 30. Only the second connector 22 with a smaller volume is installed on the motherboard 30, thereby reducing the space required for the motherboard 30, thereby reducing the factors affecting the miniaturization of the product; the internal design space of the electronic product can be reduced, and the user's demand for miniaturization and lightness of the electronic product can be met;

[0051] The installation of the wireless network module is simple and quick, which can save production and assembly costs, labor costs, etc.
