Examples

Referring to fig. 1, the present embodiment provides a lightning protection device, specifically a 1U lightning protection device, which includes a base 100, a pressure sensitive mechanism 200, a remote signaling mechanism 300 (referring to fig. 4), a first wire 400 and a second wire 500. Wherein, the pressure sensitive mechanism 200 is detachably connected with the base 100, the remote signaling mechanism 300 is disposed on the base 100, and the first wire 400 and the second wire 500 are connected with the base 100.

Referring to fig. 2, specifically, a first conductive element 110 and a second conductive element 120 are disposed on the base 100. The first conductive member 110 is electrically connected to the first conductive wire 400, and the second conductive member 120 is electrically connected to the second conductive wire 500.

Further, when the pressure sensitive mechanism 200 is mounted on the base 100, the pressure sensitive mechanism 200 is in contact with and conducted with the first conductive member 110 and the second conductive member 120, respectively.

In some embodiments, the first conductive element 110 is in the form of a sheet, and the first conductive wire 400 has a flat first connection portion 410. The first connection portion 410 is attached to one end of the first conductive member 110 and is connected thereto by a bolt.

Similarly, the second conductive member 120 has a sheet shape, and the second conductive wire 500 has a flat second connection portion 510. The second connection portion 510 is attached to one end of the second conductive member 120 and is connected thereto by a bolt.

Referring to fig. 3 and 4, in particular, the pressure sensitive mechanism 200 includes a housing 210 and a pressure sensitive assembly 220.

Wherein, the housing 210 is detachably connected with the base 100, and the pressure sensitive component 220 is disposed on the housing 210. When the housing 210 is mounted on the base 100, the pressure sensitive component 220 is in contact with and conductive with the first conductive member 110 and the second conductive member 120, respectively.

In some embodiments, the housing 210 is clamped to the base 100 along a connecting line between itself and the base 100, which is schematically indicated by an X direction.

Specifically, the pressure sensitive assembly 220 includes a mounting base 221, a high Wen Yinjiao spring 222, a pressure sensitive resistor (not shown), a low pressure sensitive Wen Yinjiao, a split spring 224, a moveable member 225, and a tension spring 226.

Wherein, the mounting base 221 is clamped with the housing 210, and the high Wen Yinjiao spring 222, the piezoresistor, the pressure sensitive low Wen Yinjiao, the separating spring 224, the movable member 225 and the tension spring 226 are all disposed on the mounting base 221.

One end of the high-temperature pin elastic sheet 222 is convexly arranged on the surface of the mounting seat 221 and is in a U-shaped arrangement, and the other end of the high Wen Yinjiao elastic sheet 222 is electrically connected with the piezoresistor.

The pressure sensitive low Wen Yinjiao 223 is provided on the piezo-resistor.

One end of the separation spring 224 is convexly arranged on the surface of the mounting seat 221, and is also in a U-shaped arrangement, and the other end of the separation spring 224 is welded with the pressure-sensitive low-temperature pin 223 in a low-temperature tin manner.

In addition, when the housing 210 is mounted on the base 100, the high temperature pin dome 222 and the separation dome 224 penetrate into the base 100. The high temperature pin elastic piece 222 is in contact conduction with one end of the first conductive piece 110 far away from the first conductive wire 400, and the separation elastic piece 224 is in contact conduction with one end of the second conductive piece 120 far away from the second conductive wire 500.

The movable member 225 is slidably disposed on the mounting base 221, and the tension spring 226 is parallel to the sliding direction of the movable member 225. One end of the tension spring 226 is connected to the mounting base 221, and the other end is connected to the movable member 225.

During normal operation, the separation spring 224 is welded with the pressure sensitive low Wen Yinjiao, and is electrically connected with the high temperature pin spring 222 through the piezoresistor, so that the internal elements of the pressure sensitive mechanism 200 are in a conducting state. At this time, the separating spring 224 is bent and deformed toward the low pressure sensitive portion Wen Yinjiao, and abuts against a side of the movable member 225, which is close to the tension spring 226, so as to prevent the movable member 225 from sliding, and the movable member 225 is in the first position.

When the electric circuit and the communication circuit are damaged by lightning attack or other transient overvoltage, the piezoresistor fails to generate heat, and the generated heat is conducted to the welding point of the separation elastic sheet 224 and the pressure-sensitive low Wen Yinjiao, so that tin at the welding point is melted. Under the action of the self stress of the separation spring 224 and the tensile force of the tension spring 226, the separation spring 224 is separated from the pressure-sensitive low-temperature pin 223, and the internal elements of the pressure-sensitive mechanism 200 are disconnected. At this time, the movable member 225 is no longer limited by the separating spring 224, and slides under the traction of the tension spring 226, leaving the first position.

Referring to fig. 4 and 5, further, the housing 210 is disposed towards one end of the base 100 and exposes an end surface of the mounting base 221. The end surface of the mounting base 221 is provided with a positioning portion 221a, and the base 100 is correspondingly provided with a positioning groove 130.

When the housing 210 is engaged with the base 100 in a correct posture, the positioning portion 221a of the mounting base 221 is aligned with the positioning slot 130 and is embedded in the positioning slot 130. After the casing 210 rotates 180 ° around the X direction, the casing 210 still can be clamped with the base 100, but the positioning portion 221a is dislocated from the positioning slot 130, so that the casing 210 cannot be completely clamped with the base 100, thereby prompting the staff that the casing 210 is in a wrong posture and playing a role in preventing reverse installation.

Referring to fig. 6, further, an end surface of the housing 210 facing away from the end of the base 100 is provided with a warning window 211. Correspondingly, the movable member 225 is provided with a first indicating portion 225a, the mounting base 221 is provided with a second indicating portion 221b, and the second indicating portion 221b is opposite to the warning window 211.

When the movable member 225 is in the first position, the first indication portion 225a shields the second indication portion 221 b. When the movable member 225 leaves the first position, the first indicator portion 225a moves away, so that the second indicator portion 221b is exposed.

The operator observes through the warning window 211, and if the first indicator 225a is observed, it indicates that the pressure-sensitive mechanism 200 is in a normal operation state, and if the second indicator 221b is observed, it indicates that the pressure-sensitive mechanism 200 is failed and needs to be repaired or replaced.

In some embodiments, the first indicator 225a and the second indicator 221b are different colors.

Alternatively, the first indicator 225a is green in color and the second indicator 221b is red in color.

Referring again to fig. 4 and 5, in particular, the remote signaling mechanism 300 includes a remote signaling circuit board 310, a remote signaling conductor 320, a remote signaling transmission 330, and a remote signaling terminal 340.

The remote signaling circuit board 310 and the remote signaling terminal 340 are fixedly disposed on the base 100, and the remote signaling circuit board 310 is electrically connected to the remote signaling terminal 340.

The remote signaling transmission member 330 is slidably disposed on the base 100 along the X direction, one end of the remote signaling transmission member 330 is connected to the remote signaling conducting member 320, and the remote signaling transmission member 330 is located on a side of the remote signaling conducting member 320 facing away from the remote signaling circuit board 310. In addition, the mounting base 221 is provided with a through hole 221c for allowing the remote signaling transmission member 330 to penetrate.

When the housing 210 is engaged with the base 100, the movable member 225 in the first position aligns with the remote signaling transmission member 330 and abuts against an end of the remote signaling transmission member 330 away from the remote signaling conducting member 320, so as to drive the remote signaling transmission member 330 to slide towards the remote signaling circuit board 310. At this time, the remote signaling transmission member 330 presses the remote signaling conducting member 320 against the remote signaling circuit board 310, so that the remote signaling conducting member 320 contacts and conducts with the remote signaling circuit board 310 in series, and the entire remote signaling mechanism 300 is a path.

In some embodiments, both the remote signaling conductors 320 and the remote signaling circuit board 310 are gold plated or highly reliable plated to reduce contact resistance therebetween and prevent oxidation-induced contact failure.

When the electrical circuit, communication line, or other transient overvoltage causes damage, the moveable member 225 moves away from the first position and no longer abuts the remote signaling transmission member 330. At this time, the remote signaling transmission member 330 slides back to the remote signaling circuit board 310, and penetrates into the mounting base 221 through the through hole 221c. The remote signaling conducting piece 320 is disconnected from the remote signaling circuit board 310, the whole remote signaling mechanism 300 is open, and an electrical signal is output through the remote signaling terminal 340 to prompt the staff to repair and replace.

The existing remote signaling structure generally adopts a pressing rod or a pushing rod to control the micro switch, so as to control the on-off of a remote signaling passage. However, interference may occur during the operation, which may cause abnormal output of the micro switch signal. In addition, the micro-switch is easily damaged by high temperature in the welding and mounting process, so that the action mechanism is damaged and cannot work normally, and the working voltage, current and insulation withstand voltage of the micro-switch are low, so that the application range is limited.

Compared with the existing remote signaling structure, the remote signaling mechanism 300 adopts the remote signaling transmission part 330 to drive the remote signaling conducting part 320 to move, so that the remote signaling conducting part 320 is in contact with or separated from the remote signaling circuit board 310, and the remote signaling mechanism is not affected by high temperature caused by conventional installation operation in the manufacturing process. In addition, the distance between the remote signaling conducting element 320 and the remote signaling circuit board 310 can be designed to be 3mm or more, which is far greater than the contact distance of the micro switch, the working voltage and current are large, and the insulation withstand voltage is high.

In one embodiment, one end of the remote signaling transmission member 330 abuts against the movable member 225, and the other end of the remote signaling transmission member 330 is fixedly connected to the remote signaling conducting member 320.

In addition, the remote signaling mechanism 300 also includes a reset 350. The reset element 350 is disposed on the base 100, and is used to slide the remote signaling transmission element 330 back toward the remote signaling circuit board 310 after the movable element 225 leaves the first position.

Optionally, the restoring member 350 is a compression spring. One end of the compression spring is abutted with the base 100, and the other end of the compression spring is in detail with the remote signaling transmission piece 330.

When the remote signaling transmission member 330 presses the remote signaling conducting member 320 against the remote signaling circuit board 310, so that the remote signaling conducting member 320 contacts and conducts with the remote signaling circuit board 310, the compression spring is in a compressed state.

Further, the middle part of the remote signaling conducting member 320 is fixedly connected with one end of the remote signaling transmission member 330, and two ends of the remote signaling conducting member 320 are arranged in an arch shape and can be elastically deformed when contacting with the remote signaling circuit board 310.

At this time, the remote signaling mechanism 300 adopts dual-elasticity control in the action structure, so that the reliability is greatly increased, and the remote signaling conducting member 320 can be ensured to be separated from the remote signaling circuit board 310 after the movable member 225 leaves the first position.

Referring to fig. 7 and fig. 8 together, in another embodiment, the remote signaling conducting element 320 is an elastic element, and one end of the remote signaling conducting element 320 is fixedly connected to the remote signaling circuit board 310, and the other end of the remote signaling conducting element 320 is separated from the remote signaling circuit board 310 in a natural state. In addition, the remote signaling transmission member 330 abuts against the remote signaling conducting member 320.

When the remote signaling transmission member 330 slides toward the remote signaling circuit board 310 under the supporting of the movable member 225, the remote signaling transmission member 320 is deformed. When the movable member 225 moves away from the first position, the remote signaling conducting member 320 drives the remote signaling transmission member 330 to slide back toward the remote signaling circuit board 310 until the natural state is restored.

When the lightning protection device is used, a worker clamps the housing 210 to the base 100, so that the high Wen Yinjiao elastic sheet 222 contacts and conducts with the first conductive member 110, and the separation elastic sheet 224 contacts and conducts with the second conductive member 120, so that the internal elements of the pressure-sensitive mechanism 200 are also in a conducting state.

At this time, the movable member 225 is at the first position, and contacts the remote signaling conducting member 320 via the remote signaling transmission member 330 to make the remote signaling conducting member 320 contact and conduct with the remote signaling circuit board 310. The entire remote signaling mechanism 300 is a passage, and a worker can observe the green first indication portion 225a through the warning window 211.

When the electrical circuit and the communication line are damaged by lightning strike or other transient overvoltage, the separation spring 224 is separated from the pressure-sensitive low-temperature pin 223, the internal elements of the pressure-sensitive mechanism 200 are disconnected, and the power supply is timely cut off, so that the back-end equipment is protected. At the same time, the movable member 225 is pulled by the tension spring 226 to leave the first position and no longer abuts against the remote signaling transmission member 330. The remote signaling conducting piece 320 is disconnected from the remote signaling circuit board 310, the whole remote signaling mechanism 300 is open, and an electrical signal is output through the remote signaling terminal 340 to prompt the staff to repair and replace. In addition, the worker can observe the red second indication portion 221b through the warning window 211, thereby recognizing and confirming the failure of the pressure-sensitive mechanism 200.

In the maintenance and replacement process, a worker can directly take down the housing 210 from the base 100 and replace the pressure sensitive mechanism 200 with a new one, and compared with the existing PCB-mounted lightning protection device, the operation is simpler and more convenient.

In addition, the height of the lightning protection device is 40mm, the assembly requirement of small space of the 1U chassis is met, and the problem that the existing guide rail type lightning protection device cannot be installed in the 1U chassis is solved.

In a word, the lightning protection device has compact structure, miniaturization and high safety performance, can be inserted and pulled in the space of the panel of the 1U chassis, and has functions of reverse installation prevention, falling prevention, failure window warning and the like.

In some embodiments, the lightning protection device described above includes only one set of base 100, pressure sensitive mechanism 200, telemetry signaling mechanism 300, first conductor 400, and second conductor 500.

Referring to fig. 9, in other embodiments, the lightning protection device may also be composed of two sets of bases 100, pressure sensitive mechanisms 200, remote signaling mechanisms 300, a first wire 400, and a second wire 500 connected in parallel. Wherein, two bases 100 are fixedly connected by rivets 600.

Referring to fig. 10, further, two remote signaling mechanisms 300 share a remote signaling circuit board 310 and a remote signaling terminal 340, and the remote signaling circuit board 310 cooperates with two remote signaling conductors 320.

Referring to fig. 11, when two remote signaling conductors 320 are simultaneously in contact with the remote signaling circuit board 310, the two remote signaling conductors 320 are connected in series. If any one of the remote signaling conductors 320 is separated from the remote signaling circuit board 310 or both of the remote signaling conductors 320 are separated from the remote signaling circuit board 310 at the same time, the remote signaling mechanism 300 becomes an open circuit and outputs an electrical signal through the remote signaling terminal 340.

Referring to fig. 12, in still other embodiments, the lightning protection device may further comprise three sets of bases 100, pressure sensitive mechanisms 200, remote signaling mechanisms 300, a first wire 400, and a second wire 500 connected in parallel. Similarly, three bases 100 are fixedly connected by rivets 600.

Referring to fig. 13 and 14, in addition, three remote signaling mechanisms 300 share a remote signaling circuit board 310 and a remote signaling terminal 340, and the remote signaling circuit board 310 cooperates with three remote signaling conductors 320. When three remote signaling conductors 320 are simultaneously in contact with the remote signaling circuit board 310, the three remote signaling conductors 320 are connected in series.
