Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection, in particular to a surge protector base and a surge protector. Background Art

[0002] SPD, or surge protector, is also called lightning arrester. It is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. In a low-voltage power distribution system, when a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, such as overvoltage caused by lightning, thereby avoiding damage to other equipment in the circuit caused by the surge. The SPD surge protector can discharge lightning current and protect electrical equipment from lightning strikes. A surge protector generally includes a surge protector base and a surge protector module box that can be plugged into the surge protector base. If multiple surge protector module boxes are plugged into the surge protector base at the same time, a corresponding number of micro switches need to be set in the base to realize the remote signal alarm function. This method occupies a large installation space and is not conducive to the miniaturization of the surge protector. Summary of the invention

The first end of the pressure plate is rotatably arranged in the lower shell, and the second end is overlapped on the at least two groups of remote signaling components. The pressure plate is pressed against the micro switch. The surge protector module box is in contact with the at least two groups of remote signaling components and applies compression force to the at least two groups of remote signaling components. When the surge protector module box is tripped, the at least two groups of remote signaling components release the compression force, so that the second end of the pressure plate moves and releases the micro switch.

[0005] Optionally, each of the at least two groups of remote signaling components includes a remote signaling rod, a spring and a clamping piece. The clamping piece fixing ring is arranged on the remote signaling rod. One end of the spring abuts against the inside of the lower shell, and the other end abuts against the clamping piece.

The first elastic torsion bar and the second elastic torsion bar are respectively two ends of the torsion spring body extending in different directions. The torsion spring body is sleeved on the first end of the pressure plate. The first elastic torsion bar is fixedly arranged in the lower shell. The second elastic torsion bar is pressed on the pressure plate.

[0007] Optionally, a limiting groove is provided on the pressure plate. The second elastic torsion bar of the torsion spring is arranged in the limiting groove. The first end of the pressure plate is a cylindrical shaft. The cylindrical shaft is rotatably mounted in the lower shell.

The at least two lap blocks are respectively lapped on the clamping parts of the at least two groups of remote signal assemblies.

[0008] Optionally, at least two remote signal component accommodating grooves are provided in the lower shell.

The four groups of remote signaling components are respectively arranged in the four remote signaling component accommodating grooves. The pressure plate includes four overlapping blocks. The four overlapping blocks are simultaneously overlapped on the four clamping parts of the four groups of remote signaling components.

[0010] Optionally, a limiting notch is provided on one side of each of the four remote signal component accommodating grooves. One side of each of the clamping parts in the four groups of remote signal components extends toward the pressure plate to form a convex arm. The four convex arms extend from the four limiting notches respectively. The four overlapping blocks of the pressure plate overlap the four convex arms respectively at the same time.

[0011] Optionally, the surge protector base further includes a cover body, and the cover body and the lower shell are buckled with each other.

[0012] The utility model also provides a surge protector. The surge protector comprises a surge protector module box and the surge protector base. The surge protector module box is plugged into the surge protector base.

[0013] Optionally, the surge protector module box includes a varistor and a tripping mechanism. The tripping mechanism includes an elastic recovery member. The tripping mechanism is electrically connected to the varistor through low-temperature soldering. The initial state of the elastic recovery member is a compressed state.

When the temperature of the varistor exceeds the low-temperature soldering melting temperature threshold, the tripping mechanism is disconnected from the varistor, the elastic recovery member stretches and resets, so that the tripping mechanism is removed from the remote signal component, and the remote signal component releases the compression force.

[0014] The utility model provides a surge protector base, which can realize the tripping of any one of the multiple surge protector module boxes by setting a pressure plate and a transmission cooperation with a remote signal component, and the remote signal component drives the pressure plate to release the micro switch, thereby realizing the remote signal alarm function.

[0023] See also Figure 1 and Figure 3 , a surge protector 999 is provided in one embodiment of the utility model. The surge protector 999 includes a surge protector module box 997 and a surge protector base 998 provided in one embodiment of the utility model. The surge protector module box 997 can be plugged into the surge protector base 998. The surge protector 999 discharges current to the ground when there is a lightning strike or system overvoltage to protect the electrical appliances in the circuit. In this embodiment, four surge protector module boxes 997 are connected together and plugged into the surge protector base 998. In other embodiments, two, three or other numbers of surge protector module boxes 997 can also be plugged into the surge protector base 998.

[0024] See also Figure 2 The surge protector module box 997 includes a varistor 910 and a tripping mechanism 920. The tripping mechanism 920 is electrically connected to the varistor 910 by low-temperature soldering. The tripping mechanism 920 includes an elastic recovery member 922. When the circuit is normally turned on, the elastic recovery member 922 is in a compressed state, that is, the initial state of the elastic recovery member 922 is a compressed state.

[0025] See also Figure 3 , an embodiment of the utility model provides a surge protector base 998. Figure 2 and Figure 4The surge protector base 998 includes a micro switch 100, a pressure plate 200, four groups of remote signal components 300, a torsion spring 400, a lower shell 500 and a cover 600. The micro switch 100, the pressure plate 200, the four groups of remote signal components 300 and the torsion spring 400 are arranged in the lower shell 500. The first end 210 of the pressure plate 200 is rotatably arranged in the lower shell 500, and the second end 220 is overlapped on the four groups of remote signal components 300. The pressure plate 200 presses against the micro switch 100. The torsion spring 400 is sleeved on the first end 210 of the pressure plate 200, and one end is fixedly arranged in the lower shell 500, and the other end is pressed on the pressure plate 200, which is used to limit the rotation range of the pressure plate 200 and facilitate the rotation and reset of the pressure plate 200. The cover 600 and the lower housing 500 are buckled with each other, and the micro switch 100, the pressure plate 200, the four groups of remote signal components 300 and the torsion spring 400 are stored therein. In this embodiment, the remote signal components 300 are arranged in four groups, which are arranged one by one with the four surge protector module boxes 997. The second end 220 of the pressure plate 200 is simultaneously overlapped on the four groups of remote signal components 300. In other embodiments, the number of remote signal components 300 can also be set to two, three or other numbers, and the specific number corresponds to the number of surge protector module boxes 997.

[0026] See also Figure 1 , Figure 2 and Figure 6 , four surge protector module boxes 997 are inserted into the surge protector base 998, and the tripping mechanism 920 of the surge protector module box 997 abuts against the remote signal component 300 and applies compression force to the remote signal component 300. At this time, the elastic return member 922 of the tripping mechanism 920 is also in a compressed state, and the pressure plate 200 presses against the micro switch 100, so that the circuit is normally turned on. When lightning strikes or the system is overvoltage, the temperature of the varistor 910 rises. When the temperature of the varistor 910 exceeds the low-temperature soldering melting temperature threshold, the tripping mechanism 920 is disconnected from the varistor 910, and the elastic recovery member 922 stretches to move the tripping mechanism 920 away from the remote signal component 300. The remote signal component 300 releases the compression force and moves, driving the second end 220 of the pressure plate 200 to rotate around the first end 210, releasing the microswitch 100, disconnecting the circuit, and sending a remote signal alarm signal. After receiving the alarm signal, the user can deal with the surge protector 999 in time.

[0027] See also Figure 4-5, the first end 210 of the pressing plate 200 is a cylindrical shaft. The cylindrical shaft is rotatably mounted in the lower shell 500. The second end 220 of the pressing plate 200 extends four overlapping blocks 222 in the direction of the remote signal assembly 300. The four overlapping blocks 222 are overlapped on the remote signal assembly 300 at the same time. A limiting groove 240 is provided on the pressing plate 200. The limiting groove 240 is arranged near the torsion spring 400, and is extended and recessed from the first end 210 of the pressing plate 200 to the second end 220. In the present embodiment, the number of overlapping blocks 222 is four, which are overlapped on four groups of remote signal assemblies 300 one by one. In other embodiments, the number of overlapping blocks 222 may also be two, three or other numbers, and the specific number corresponds to the number of remote signal assemblies 300.

[0028] See also Figure 4-5 , the structures of the four groups of remote signaling assemblies 300 are consistent. Each of the four groups of remote signaling assemblies 300 includes a remote signaling rod 320, a spring 340 and a clamping member 360. The clamping member 360 fixing ring is arranged on the remote signaling rod 320. One end of the spring 340 abuts against the lower shell 500, and the other end abuts against the clamping member 360. The remote signaling rod 320 and the clamping member 360 can move up and down under the action of the spring 340. One side of the clamping member 360 extends in the direction of the pressure plate 200 to form a protruding arm 362. In this embodiment, the number of the remote signaling rod 320, the spring 340, the clamping member 360 and the protruding arm 362 is four.

[0029] See also Figure 4-5 The torsion spring 400 includes a torsion spring body 420, a first elastic torsion bar 440 and a second elastic torsion bar 460. The first elastic torsion bar 440 and the second elastic torsion bar 460 are respectively two ends of the torsion spring body 420 extending in different directions. The first elastic torsion bar 440 and the second elastic torsion bar 460 can be elastically twisted around the torsion spring body 420. The torsion spring body 420 is sleeved on the cylindrical shaft of the first end 210 of the pressure plate 200. The first elastic torsion bar 440 is fixedly arranged in the lower shell 500. The second elastic torsion bar 460 is pressed on the pressure plate, specifically, the second elastic torsion bar 460 is arranged in the limiting groove 240 of the pressure plate 200. The limiting groove 240 limits the activity space of the second elastic torsion bar 460 to prevent the second elastic torsion bar 460 from slipping out of the pressure plate 200.

[0030] See also Figure 4-5The lower shell 500 is provided with a pressure plate mounting shaft hole 520 and four remote signal component accommodating grooves 540. The cylindrical shaft of the first end 210 of the pressure plate 200 is rotatably inserted and installed in the pressure plate mounting shaft hole 520. The remote signal component accommodating groove 540 is a cylindrical groove extending upward from the bottom surface of the lower shell 500. The four groups of remote signal components 300 are respectively arranged in the four remote signal component accommodating grooves 540. A limiting notch 542 is provided on one side of each of the four remote signal component accommodating grooves 540. The four protruding arms 362 on the four clamping members 360 extend from the four limiting notches 542 respectively. The four overlapping blocks 222 on the pressure plate 200 are overlapped on the four protruding arms 362 at the same time.

[0031] When the circuit is normally turned on, the four tripping mechanisms 920 in the four surge protector module boxes 997 are respectively abutted against the four groups of remote signaling components 300. Specifically, the tripping mechanisms 920 abut against the remote signaling rods 320 and compress the springs 340. The torsion springs 340 press the pressing plate 200, and the four overlapping blocks 222 of the pressing plate 200 are respectively and simultaneously overlapped on the four convex arms 362 of the four groups of remote signaling components 300, and the pressing plate 200 is pressed against the micro switch 100 at the same time. When lightning strikes or the system is over-voltage, any one or more of the four groups of surge protector module boxes 997 will trip, and the spring 340 in the corresponding group of remote signal components 300 will release the compression force and move the remote signal rod 320 and the clamping piece 360 ​​upward, and the protruding arm 362 of the clamping piece 360 ​​will move along the opening direction of the limiting notch 542, and the pressure plate 200 will rotate around the first end 210 through the overlapping block 222 of the pressure plate 200, releasing the micro switch 100, disconnecting the circuit, and sending a remote signal alarm signal. After receiving the alarm signal, the user can deal with the surge protector 999 in time.

[0032] In this embodiment, through the transmission cooperation of four groups of remote signaling components 300 and the pressure plate 200, only one micro switch 100 needs to be set in the surge protector base 998, so that any surge protector module box 997 of the surge protector 999 can be tripped. The micro switch 100 can be released by a pressure plate 200 to send a remote signaling alarm signal. There is no need to set four groups of micro switches and four groups of remote signaling components for transmission cooperation in the traditional way, which greatly saves the space in the surge protector base 998 and is conducive to the miniaturization of the surge protector base 998.

[0033] The utility model provides a surge protector base, which can realize the tripping of any one of the multiple surge protector module boxes by setting a pressure plate and a transmission cooperation with a remote signal component, and the remote signal component drives the pressure plate to release the micro switch, thereby realizing the remote signal alarm function. The surge protector base provided by the utility model optimizes the traditional multiple micro switches into one micro switch, and the remote signal alarm function can be realized by pressing or releasing the micro switch through the transmission cooperation of the pressure plate and multiple groups of remote signal components, which greatly saves the number of accessories and the occupied space, realizes the miniaturization of the surge protector base, and thus realizes the miniaturization and thinness of the surge protector.
