[0002] An attenuator is an electronic component whose main purpose is to adjust the size of the signal in the circuit, directly read the attenuation value of the network under test in the comparison measurement circuit, and improve impedance matching. The attenuator can introduce a predetermined attenuation within a specified frequency range, usually indicated in decibels and the ohm value of the characteristic impedance.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing attenuator is installed and used by the staff, the connection between the plug and the attenuator is only achieved by ordinary plugging. After long-term use, the plug and the connection are prone to fall off and loosen, thereby affecting the use of the attenuator. Utility Model Content

After long-term use, the plug and the connection are prone to fall off and loosen, thereby affecting the use of the attenuator.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a limiting amplifier attenuator, comprising a transmission rod, one end of which is provided with an input port, the other end of which is provided with an output port, both ends of which are provided with plug pins, an attenuation sheet is provided inside the transmission rod, and a plug-in mechanism: the plug-in mechanism comprises a swivel arranged inside the output port, the outer surface of the swivel is fixedly connected with a connecting rod, the inside of the output port is rotatably connected with a spring clamp, and the outer surface of the output port is provided with a guide assembly; a heat dissipation mechanism: the heat dissipation mechanism is arranged inside the transmission rod.

[0008] Furthermore, the heat dissipation mechanism comprises a groove arranged inside the transmission rod, heat dissipation holes are evenly opened inside the groove, and a heat insulation component is installed on the outer surface of the transmission rod.

[0013] Furthermore, a rotation groove is formed on the outer surface of the output port, and the rotating ring passes through the rotation groove.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] The utility model is provided with a plug-in mechanism. A worker flips the output port so that the output port rotates to drive a swivel ring fixedly connected at one end to rotate, so that the slider slides inside the slide groove, so that a spring clamping block fixedly connected to the slider at one end is guided and flipped inside the guide frame, so that the guide frame is retracted to the inside of the output port through the extension opening.
