Description

Technical Field

[0001] This utility model relates to the field of surge protector detection, specifically a surge protector detection device that is easy to install. Background Technology

[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a surge current or voltage spike suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in a very short time, thereby preventing damage to other equipment in the circuit. Surge protectors are suitable for AC 50 / 60Hz power supply systems with a rated voltage of 220V / 380V, protecting against surges caused by indirect and direct lightning strikes or other transient overvoltages. They are suitable for surge protection requirements in residential homes, the service industry, and industrial sectors.

[0003] In the installation and use of surge protectors, they are typically mounted on the DIN rail of the distribution cabinet. A lightning counter is then installed on one side of the surge protector to monitor its operation, detecting the number and duration of lightning strikes, as well as the switching status of the surge protector. The lightning counter uses a current sensor connected to the outer wall of the grounding wire at the bottom of the surge protector. Since the current sensor and the lightning counter are connected by a wire, and the wire is relatively weak, and the inner diameter of the current sensor is larger than the outer diameter of the grounding wire, in order to maintain the height of the current sensor, it is often necessary to shorten the connecting wire of the current sensor during actual installation. This creates compression between the current sensor and the grounding wire, thus keeping the current sensor at a fixed height. To optimize this operation, a surge protector detection device that is easy to install is provided. Utility Model Content

[0004] The purpose of this invention is to provide a surge protector detection device that is easy to install, so as to achieve the goal of conveniently fixing the current sensor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surge protector detection device that is easy to install, including a lightning counter, a fixing rod fixedly connected to the lower end of the lightning counter, a fixing pad fixedly connected to the bottom end of the fixing rod, a gear fixedly connected to the upper surface of the fixing pad, and the gear fixedly connected to the outer wall of the fixing rod, the gear being used to fix and connect the fixing mechanism;

[0006] The upper end of the gear is provided with a fixing mechanism, which includes a connecting block, a connecting groove, a C-shaped card seat, and a tooth groove;

[0007] The C-shaped bracket is inserted into the outer wall of the fixing rod. The connecting block is integrally formed on one side of the C-shaped bracket. The connecting block is used to connect the current sensor. The connecting groove is opened on one side of the C-shaped bracket. The toothed groove is opened on the inner wall of the C-shaped bracket. The current sensor can be installed and fixed by the engagement of the toothed groove and the gear.

[0008] As a further improvement of this utility model: the gear and the tooth groove mesh with each other, and the size of the gear matches the size of the inner cavity of the C-shaped card holder.

[0009] As a further improvement of this utility model: the thickness of the gear and the tooth groove is greater than the length of the connecting block, the connecting groove is set as a U-shaped structure, and the inner wall width of the connecting groove matches the diameter of the fixing rod.

[0010] As a further improvement of this utility model: the diameter of the fixing pad matches the diameter of the C-shaped card holder, and magnets with opposite magnetic properties are provided on the upper surface of the fixing pad and the lower surface of the C-shaped card holder.

[0011] As a further improvement of this utility model, the diameter of the central hole structure in the middle of the current sensor is larger than the diameter of the wire connected to the surge protector.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up a fixing mechanism, the sensor fixing component is fixed to one side of the connecting block. The C-shaped bracket is inserted into the outer wall of the fixing rod and then pressed down to fix the C-shaped bracket onto the gear. This avoids the problems of inconvenient installation and easy damage to the wires caused by the winding of wires in the traditional fixing method. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 In this embodiment of the utility model, a surge protector detection device that is easy to install includes a lightning counter 1. A fixing rod 2 is fixedly connected to the lower end of the lightning counter 1. A fixing pad 3 is fixedly connected to the bottom end of the fixing rod 2. A gear 4 is fixedly connected to the upper surface of the fixing pad 3. The gear 4 is fixedly connected to the outer wall of the fixing rod 2. The gear 4 is used to fix and connect the fixing mechanism 5.

[0020] The upper end of the gear 4 is provided with a fixing mechanism 5, which includes a connecting block 501, a connecting groove 502, a C-shaped card seat 503, and a tooth groove 504.

[0021] The C-type bracket 503 is inserted into the outer wall of the fixing rod 2. The connecting block 501 is integrally formed on one side of the C-type bracket 503. The connecting block 501 is used to connect the current sensor 6. The connecting groove 502 is opened on one side of the C-type bracket 503. The toothed groove 504 is opened on the inner wall of the C-type bracket 503. The current sensor 6 can be installed and fixed by the engagement of the toothed groove 504 with the gear 4.

[0022] In this embodiment: it should be noted that the lightning counter 1 is generally installed on a guide rail flush with the surge protector, while the sensor is separately fixed on the inner shelf of the distribution cabinet and located at the lower end of the surge protector. When the current sensor 6 needs to be installed, first install the lightning counter 1 on the guide rail inside the distribution cabinet, then hold the C-shaped bracket 503 and insert one side of the connecting groove 502 into the outer wall of the fixing rod 2, so that one end of the connecting groove 502 is in contact with the fixing rod 2. Lower the C-shaped bracket 503 so that the tooth groove 504 engages with the gear. On the outer wall of gear 4, the C-shaped bracket 503 is placed on the upper surface of the fixing pad 3. Through the cooperation of the above parts, the C-shaped bracket 503 is fixed on the outer wall of gear 4 and cannot be rotated left or right, thereby achieving the height fixation of current sensor 6. At the same time, simply lift the C-shaped bracket 503 and rotate it to another angle to better adapt to different situations. Compared with the traditional method of fixing current sensor 6 by winding wires, this method is more convenient and more secure, and will not damage the wires due to excessive winding.

[0023] Please refer to this carefully. Figures 1-2 Gear 4 and tooth groove 504 mesh with each other, and the size of gear 4 matches the size of the inner cavity of C-type card holder 503.

[0024] In this embodiment: through the above settings, the C-type card holder 503 can be engaged with the outer wall of the gear 4 when placed on the surface of the fixing pad 3.

[0025] Please refer to this carefully. Figure 1 The thickness of gear 4 and tooth groove 504 is greater than the length of connecting block 501. Connecting groove 502 is set as a U-shaped structure. The inner wall width of connecting groove 502 matches the diameter of fixing rod 2.

[0026] In this embodiment: With the above settings, when the C-type card holder 503 is inserted into the outer wall of the fixing rod 2 through the connecting groove 502, the tooth groove 504 and the gear 4 can be quickly aligned. And because the gear 4 and the tooth groove 504 are thick, the entire fixing mechanism 5 will not tilt due to the weight of the current sensor 6.

[0027] Please refer to this carefully. Figure 1 The diameter of the fixing pad 3 matches the diameter of the C-type card holder 503, and magnets with opposite magnetic properties are provided on the upper surface of the fixing pad 3 and the lower surface of the C-type card holder 503.

[0028] In this embodiment: the above settings ensure that the C-type card holder 503 will not easily separate or fall off when placed on the surface of the fixing pad 3 due to the attraction of the magnet.

[0029] Please refer to this carefully. Figure 1 The diameter of the central hole in the current sensor 6 is larger than the diameter of the wire connected to the surge protector.

[0030] In this embodiment: because the signal line of the surge protector is relatively thick, there is space for the surge protector to be connected when passing through the current sensor 6, and the signal line will not be unable to fit due to the small diameter of the current sensor 6.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
