Problems solved by technology

[0003] At present, due to structural problems, the traditional signal overvoltage protection device is difficult to meet the current use requirements. For example, when the signal overvoltage protection device is replaced, the communication signal transmission will be interrupted, and it is difficult to ensure the normal operation and operation of the communication equipment, which increases the signal overvoltage. The maintenance cost of the voltage protection device increases the professional technical requirements of the maintenance personnel and reduces the work efficiency of replacing the signal overvoltage protection device
The signal overvoltage protection device is installed in a vibration environment. Due to the long-term vibration state, it is easy to cause the module to fall off
Cannot detect the on-off situation of the signal line signal in time

Embodiment 1

[0030] refer to figure 1 and figure 2 , for the first embodiment of the present invention, a signal overvoltage protection device is provided, which includes a communication signal transmission mechanism 100 for normal communication signal transmission and an overvoltage protection for overvoltage protection of the communication signal transmission mechanism 100 Institution 200.

[0031] Wherein, the communication signal transmission mechanism 100 includes a housing 101, a mounting slot 102 arranged inside the housing 101, a shock absorbing slot 103 arranged below the mounting slot 102, and a communication interface 104 arranged on the side wall of the housing 100; overvoltage The protection mechanism 200 is detachably connected to the installation slot 102, and includes an installation flange 201, a contact 202 and a top rod 203. The installation flange 201 is arranged on the side wall of the overvoltage protection mechanism 200. The installation flange 201 is used to The ...

Embodiment 2

[0034] refer to image 3 and Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the installation groove 102 is divided into a first installation groove 102a and a second installation groove 102b from the outside to the inside; the first installation groove 102a includes The mounting guide rod 102a-1 corresponding to the mounting flange 201 is provided with a mounting spring 102a-2 on the mounting guide rod 102a-1; a mounting seat is provided at the bottom of the second mounting groove 102b, and the mounting seat includes a The connecting contact 102b-1 and the through hole 102b-2 that can perform electrical communication, after being installed, the connecting contact 102b-1 and the contact 202 of the overvoltage protection mechanism 200 are in electrical contact to detect the magnitude of the voltage In order to transmit the communication signal, the ejector rod 203 can fit through the through h...

Embodiment 3

[0039] refer to Figure 5 and Image 6 , which is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the communication signal transmission mechanism 100 further includes a line monitor interface 105 disposed on the side wall of the casing 101, and the line monitor interface 105 It is connected to the wire of the first conductive sheet 103a-1, and the line monitor interface 105 is connected to the line monitor. When the signal is connected, the line monitor has no response. When the line is disconnected, the line monitor cannot be obtained through the line monitor interface 105. signal, at this time, the line monitor will issue an alarm, so that the present invention can monitor the on-off condition of the signal line signal, give an early warning in time, and identify the cause of the failure.

[0040] Further, when replacing the overvoltage protection mechanism 200, pull out the limit pull rod 101b through the pull buck...

Abstract

The invention discloses a signal overvoltage protection device which comprises a communication signal transmission mechanism and an overvoltage protection mechanism. The communication signal transmission mechanism comprises a shell, a mounting groove formed in the shell, a damping groove formed below the mounting groove and a communication interface formed in the side wall of the shell; the overvoltage protection mechanism is detachably connected with the mounting groove and comprises a mounting flange, a contact and an ejector rod, the mounting flange is arranged on the side wall of the whole body of the overvoltage protection mechanism, one end of the contact is arranged at the bottom of the overvoltage protection mechanism, and the other end of the contact is connected with the ejector rod; communication signal transmission cannot be interrupted when the signal overvoltage protection device is replaced, and meanwhile the problem that the module falls off due to the fact that the signal overvoltage protection device is in a vibration state for a long time when installed in a vibration environment is solved; and the on-off condition of the signal of the signal line can be monitored, early warning can be performed in time, and fault reasons can be distinguished.

Description

technical field [0001] The present invention relates to the technical field of overvoltage protection, in particular to a signal overvoltage protection device. Background technique [0002] Overvoltage refers to the long-term voltage fluctuation phenomenon in which the rms value of the AC voltage increases at power frequency, exceeds 10% of the rated value, and lasts for more than 1 minute; the occurrence of overvoltage is usually the result of the moment when the load is switched on and off. Occurs when inductive or capacitive loads are switched on or off during normal use. Overvoltage refers to the long-term voltage fluctuation phenomenon in which the rms value of AC voltage increases at power frequency, exceeds 10% of the rated value, and lasts for more than 1 minute; the occurrence of overvoltage is usually the result of load switching, such as: Cut off a large-capacity load or add energy to the capacitor bank (overvoltage caused by excess reactive power compensation). ...
