[0031] like Figure 1-3 As shown, in one embodiment of a test jammer, the test jammer includes a base 1, a power supply 3, and multiple WiFi modules 2. The multiple WiFi modules 2 are all mounted on the base 1. Each WiFi module 2 has an access port 211 so that it can be connected to the control terminal. The WiFi modules 2 are used to output signals respectively. The power supply 3 is mounted on the base 1 and is used to supply power to each WiFi module 2.

[0032] In this embodiment, there are multiple WiFi modules 2, so that different signals can be output to simulate different environments. The diversified simulation of the environment can meet the needs of interfering with Bluetooth signals, thereby facilitating the detection of the stability and anti-interference ability of the Bluetooth signal, and solving the existing technical problem of inconvenient Bluetooth signal testing.

[0033] It should be noted that the WiFi module 2 itself can send out a WiFi signal after being powered by the power supply 3, so that interference can be carried out. The connection control end is a functional module thereof, which is a function of the WiFi module 2 itself. The means of regulation are also existing methods and will not be repeated here.

[0034] Specifically, the WiFi module 2 includes a circuit board 21, a WiFi chip, and an antenna 22. The circuit board 21 is mounted on the base 1, and the WiFi chip and antenna 22 are both connected to the circuit board 21. The circuit board 21 is provided with an access port 211 and a button 212. The button 212 is used to turn the WiFi module 2 on and off. The button 212 can also turn the corresponding WiFi module 2 on and off, further diversifying the analog signal and allowing only one or two WiFi modules 2 to be activated.

[0035] The control end can be a computer, and the output signal type of the WiFi module 2 can be adjusted and changed through the software on the computer.

[0036] In an embodiment of the test jammer, the test jammer further includes a support frame 4 , which is connected to the base 1 through legs, and each WiFi module 2 is installed on a side of the support frame 4 away from the base 1 .

[0037] In this embodiment, the support frame 4 may include a plate-like structure and a plurality of legs. Each leg has one end fixedly connected to the plate-like structure and the other end fixedly connected to the base 1. This allows for a space between the plate-like structure and the base 1, which can be used for wiring and provide thermal insulation. The fixing method may be welding, bolts, or any other method, without limitation, as long as the fixing method is sufficient.

[0038] In an embodiment of the test jammer, grooves 41 are formed at positions of the support frame 4 corresponding to the positions of the WiFi modules 2 .

[0039] In this embodiment, by providing the groove 41 , the contact area between the WiFi module 2 and the support frame 4 can be reduced, thereby facilitating the formation of a hollow area for heat dissipation.

[0040] In an embodiment of the test jammer, the bottom of the groove 41 extends along the arrangement direction of the WiFi modules 2 .

[0041] In the previous embodiment, there can be multiple grooves 41, corresponding to each WiFi module 2 respectively. In this embodiment, the groove 41 is an elongated strip extension, which is convenient for processing. Only one extended groove structure can be opened to achieve heat dissipation of all WiFi modules 2.

[0042] In one embodiment of the test jammer, the test jammer further includes a housing 5, which is mounted on the base 1 to form a housing space with the base 1. The power supply 3 is housed in the housing space. The circuit board 21 and the WiFi chip are both housed in the housing space. Each antenna 22 is disposed through the housing 5 and extends out of the housing space. The housing 5 has through holes 511 corresponding to each access port 211 and each button 212, thereby exposing each access port 211 and each button 212.

[0043] In this embodiment, by providing the cover 5, the WiFi module 2 can be prevented from being completely exposed to the outside world, leaving only the antenna 22 exposed to the outside world, which can provide better protection. In addition, it can be understood that by providing the through hole 511, it is convenient for staff to access the control terminal and touch the button 212.

[0044] In an embodiment of the test jammer, the antenna 22 includes a first section 221 and a second section 222 . The first section 221 is rotatably connected to the circuit board 21 , and the second section 222 is detachably connected to the first section 221 .

[0045] In this embodiment, by setting the antenna 22 in two sections, the antenna 22 can be detachably connected to the circuit board 21, and the antenna 22 can be rotated relative to the circuit board 21, thereby bringing better signal output, and can also be easily stored by changing the direction.

[0046] In an embodiment of the test jammer, the cover 5 includes a first cover 51 and a second cover 52 . The second cover 52 is detachably connected to the first cover 51 , and the position of the second cover 52 corresponds to the power supply 3 .

[0047] In this embodiment, by providing a second cover 52 that is detachably connected to the first cover 51, only the cover corresponding to the power supply 3 can be opened, thereby conveniently replacing the power supply 3 without having to disassemble the entire cover structure. The detachable connection between the first cover 51 and the second cover 52 can be a snap-fit ​​connection, similar to a remote control, or a boss can be provided on the first cover 51 to support the second cover 52 and then removably fixed with screws.

[0048] In an embodiment of the test jammer, the test jammer further includes a first fixing member 6, which extends along the arrangement direction of the WiFi modules 2 and abuts against each WiFi module 2. Both ends of the first fixing member 6 are fixed to the base 1 so as to fix each WiFi module 2.

[0049] In this embodiment, by setting a first fixing member 6, multiple WiFi can be fixed on the base 1. Combined with the previous embodiment, when a support frame 4 is provided, it is fixed on the support frame 4.
