Description

TECHNICAL FIELD

[0001] The utility model relates to communication equipment field, specifically, it relates to a signal source module based on frequency division. BACKGROUND

[0002] The frequency division signal source module is a signal source module integrated with frequency division function. It can not only generate specific types of signals (such as sine wave, square wave, pulse signal, etc.) according to requirements, but also divide these signals into multiple output signals with different frequency ranges and output them through output ports.

[0003] Since the existing signal source module needs to be installed inside the shell of the device during installation, and both the device shell and the signal source module have multiple models, when the signal source module is installed in the shell of a device with a different model, the input port and the output port may not match, which hinders the installation and connection of the signal source module. In the prior art, the connection between the ports is usually achieved by externally connecting wires, but there may be cases where no or few connection wires are provided, and additionally purchasing and carrying enough connection wires will increase the cost and installation burden of the device, which is not conducive to the installation of the signal source module. SUMMARY

[0004] The utility model provides a signal source module based on frequency division to solve the problem of limited installation caused by the mismatch between the signal source module and the device shell in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following scheme:

[0006] A signal source module based on frequency division, comprising a mounting plate and a signal generation module, a frequency division module and a plurality of signal output modules mounted on the mounting plate in sequence and connected by signals, further comprising a connection wire connecting the frequency division module and the signal output module, the mounting plate is provided with a mounting groove for mounting the signal output module, one side of the mounting groove is provided with a receiving cavity for receiving the connection wire, the receiving cavity is open toward the side of the mounting groove, and the frequency division module is mounted on the side of the receiving cavity away from the mounting groove.

[0007] The utility model sets a connection wire between the frequency division module and the signal output module, lengthens the connection range of the signal output module, so that the mounting plate can be installed at will within the connection range of the signal output module, avoiding the problem of limited installation caused by the mismatch between the signal source module and the device shell. At the same time, the receiving cavity is set to receive the excess connection wire, preventing the connection wire from affecting the installation of other device elements. The signal output module is fixed by the mounting groove, preventing the connection wire from being taken out of the receiving cavity due to the weight of the signal output module, facilitating the storage, transportation, use and installation of the signal source module.

[0008] Further, a slide rail is arranged on the inner wall of the storage cavity, one end of the slide rail is towards the frequency division module, the other end is towards the mounting slot, a sliding block is arranged on the slide rail, and the sliding block is mounted on the connecting wire.

[0009] The connecting wire is conveyed by the slide rail and the sliding block, the connecting wire is conveniently stored and pulled, and the probability of the connecting wire being stuck in the storage cavity is reduced.

[0010] Further, the sliding block is fixedly mounted between the two ends of the connecting wire. The length of the connecting wire between the sliding block and the signal output module is adjusted to adjust the length of the pulled-out connecting wire.

[0011] Further, a first tension spring is mounted in the storage cavity, one end of the first tension spring is connected with the sliding block, and the other end is mounted on the inner side wall of the storage cavity close to the frequency division module. The first tension spring is used for automatically storing the connecting wire, and the operation is facilitated.

[0012] Further, the connecting wire is stored in the storage cavity in an S shape. The storage and pulling of the connecting wire are more smooth, and the probability of being stuck is reduced.

[0013] Further, the length of the connecting wire is greater than the length of the storage cavity.

[0014] Further, two groups of mounting assemblies are symmetrically arranged on the mounting plate, the mounting assembly comprises two mounting columns, and a plurality of bolt holes are formed in the mounting columns. The mounting plate is mounted on the equipment shell through the mounting columns.

[0015] Further, a sliding groove is formed in the mounting plate, and the sliding groove is matched with the mounting column.

[0016] When the width of the equipment shell is greater than the longest length of the mounting plate, the mounting plate cannot be stably mounted in the equipment shell, and the mounting plate may be suspended, and the connection is not firm. Therefore, the length of the mounting column is lengthened by matching the sliding groove with the mounting column, the longest length of the mounting plate is extended, the mounting plate is conveniently erected and mounted in the equipment shell, and the mounting is more firm.

[0017] Further, a second tension spring is mounted in the sliding groove, and the second tension spring is connected with one end of the mounting column.

[0018] The mounting column has a rebound force through the second tension spring. When the mounting column is removed, the mounting column can be automatically stored. When the mounting column is mounted, the second tension spring can also provide a buffer force along the direction of the mounting column, and the vibration can be reduced.

[0019] Further, the signal output module is located between the two mounting columns on the same side. By two mounting columns to prop up a gap, facilitate signal output module stretch, traction and connection.

[0022] (2) the connecting wire is conveyed through the slide rail and the sliding block, facilitating the storage and pulling of the connecting wire, reducing the probability of the connecting wire being jammed in the storage cavity, and the connecting wire is automatically accommodated through the first tension elastic member, facilitating operation.

[0023] (3) the mounting column has a rebound force through the second tension elastic member, the mounting column can be automatically accommodated when the mounting column is removed, and the second tension elastic member can also provide a buffer force along the direction of the mounting column for the mounting plate when the mounting column is installed, so that the mounting plate can be damped.
