Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology for electrical equipment, and in particular to a connecting device for a lightning protection mechanism for electrical equipment on a building roof. Background Technology

[0002] Lightning protection for electrical equipment refers to a protective mechanism designed to prevent damage to rooftop electrical equipment from lightning strikes. Lightning is a natural phenomenon, and its powerful current and voltage can easily damage buildings and electrical equipment, especially rooftop electrical equipment such as communication antennas, solar panels, and air conditioners, which are usually exposed and easily become targets of lightning strikes. Therefore, the design and installation of lightning protection mechanisms for rooftop electrical equipment are important measures to ensure the safe operation of equipment and prevent lightning-induced fires or equipment damage. The connection device refers to the component that connects the lightning conductor to the grounding device. Common lightning conductors include lightning rods, while grounding devices include lightning protection strips installed at the edge of the roof.

[0003] In actual installation, existing lightning rods and lightning arresters are generally connected and installed by bolt assemblies, which are used to tighten the terminal plates at both ends of the conductor to the lightning rod base and the side of the lightning arrester to achieve the effect of conductive transmission. However, the bolt assemblies may loosen over time. Once the bolt assemblies loosen, the terminal plates will not be able to make tight contact with the conductive surface of the equipment, thus affecting the conductivity during actual use. At the same time, the bolt assemblies are generally exposed, and long-term use will cause rusting, further affecting the overall conductivity of the device, resulting in poor overall practical safety performance.

[0004] Therefore, in view of the problem that the existing lightning rods and lightning arresters have poor practical safety performance during actual connection and installation, this utility model achieves automatic elastic limiting of the terminal block by setting two sets of "[" shaped contact frames in opposite directions and cooperating with contact spring assemblies. Compared with the existing bolt crimping method, it avoids the problem of poor contact between the terminal block and the conductive surface of the equipment due to loose bolts, and effectively improves the connection stability and conductivity of the lightning rod and lightning arrester. Utility Model Content

[0005] To overcome the common problem that lightning rods and lightning protection strips have poor practical safety performance when actually connected and installed.

[0006] The technical solution of this utility model is as follows: a connecting device for a lightning protection mechanism for electrical equipment on a building roof, comprising a ground base, a base body, a lightning rod body, and a lightning interceptor strip body.

The sides of the snap-fit ​​positioning mechanism are provided with a distance adjustment mechanism. The outside of the distance adjustment mechanism is provided with a protective cover mechanism. Positioning boxes are slidably installed on the outer side walls of the base body and the outer side walls of the single lightning interceptor strip body.

[0007] Preferably, the snap-fit ​​positioning mechanism includes a placement slot, a contact frame, a contact spring, a terminal block, and a wire. The bottom outer wall of the positioning box is set as an open structure, and the placement slot is opened inside the positioning box. Rectangular slots are symmetrically opened through the inner walls of the positioning box on both sides of the placement slot. Two sets of cylindrical slots are symmetrically installed through the inner walls of the positioning box on both sides of the rectangular slot. A contact frame is slidably installed inside the rectangular slot. A contact spring is symmetrically arranged on the outer side of the contact frame, and the end of the contact spring is connected to the inner wall of the bottom of the placement slot. Limiting blocks are symmetrically arranged on the outer sides of the contact frame. A limiting groove is correspondingly opened on the inner side of the positioning box for the sliding installation of the limiting block. The limiting groove is connected to the internal space of the rectangular slot. The terminal block is installed in the middle position of the two sets of contact frames, and a wire is crimped to the lower end of the terminal block.

[0008] Preferably, the contact surfaces of the positioning box with the base body and the lightning protection strip body are configured as open structures, and the outer side wall of the terminal block is in contact with the outer side wall of the base body.

[0009] Preferably, the contact bracket is configured in the shape of "[", and the outer walls of the top and bottom of the protruding foot at the bottom of the contact bracket are both configured as arc-shaped structures, and the four sides of the terminal block are all configured as arc-shaped structures.

[0010] Preferably, the distance adjustment mechanism includes a positioning mounting strip, an abutment strip, and an abutment slot. The positioning mounting strip is fixedly installed on the outer side wall of the base body, and the abutment strip is fixedly installed on the outer side wall of the positioning box. The top outer wall of the positioning mounting strip is provided with an abutment slot for the abutment strip to be inserted and installed.

[0011] Preferably, the positioning mounting strip has a positioning threaded groove that is evenly spaced through the outer wall of its side at the position of the contact slot, and the outer wall of the contact strip has a mating threaded groove that is through the side, and fastening bolts are installed inside the positioning threaded groove and the mating threaded groove.

[0012] Preferably, the sealing and protective mechanism includes a reinforcing support base, a protective cover, a positioning strip, and a positioning slot.

Furthermore, by installing a protective cover on the outside of the device, the overall rain resistance and long-term safety of the device are enhanced through the protective effect of the cover. The overall structural design is safe and has good practical effect. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-7 This utility model provides a technical solution: a connection device for a lightning protection mechanism for electrical equipment on a building roof, including a ground base 1, a base body 2, a lightning rod body 3, and a lightning interceptor strip body 4. The base body 2 and the lightning interceptor strip body 4 are fixedly installed on the top outer wall of the ground base 1. The lightning rod body 3 is supported and installed on the upper end of the base body 2. The sides of the base body 2 and the lightning interceptor strip body 4 are provided with a snap-fit ​​positioning mechanism 5. The sides of the snap-fit ​​positioning mechanism 5 are provided with a distance adjustment mechanism 6. The outside of the distance adjustment mechanism 6 is provided with a sealing protection mechanism 7. The side outer wall of the base body 2 and the side outer wall of the single lightning interceptor strip body 4 are slidably installed with positioning boxes 501. It should be noted that the installation method of the base body 2 and the lightning rod body 3 can refer to the existing installation structure, which is a conventional operation technique and will not be described in detail here.

[0026] The snap-fit ​​positioning mechanism 5 includes a placement groove 502, a contact frame 505, a contact spring 506, a terminal block 509, and a wire 5010. The bottom outer wall of the positioning box 501 is open, and the placement groove 502 is provided inside the positioning box 501. Rectangular grooves 503 are symmetrically provided through the inner walls of the positioning box 501 at the placement groove 502. Two sets of cylindrical grooves 504 are symmetrically installed through the inner walls of the positioning box 501 at the rectangular grooves 503. The contact frame 505 is slidably installed inside the rectangular grooves 503. The contact springs 506 are symmetrically provided on the outer walls of the sides of the contact frame 505, and the ends of the contact springs 506 are connected to the inner wall of the bottom of the placement groove 502. Limiting blocks 507 are symmetrically arranged on both outer walls of 505. The inner side wall of positioning box 501 is correspondingly provided with limiting grooves 508 for sliding installation of limiting blocks 507. The limiting grooves 508 are connected to the internal space of rectangular groove 503. The terminal block 509 is installed in the middle of the two sets of contact frames 505, and the lower end of the terminal block 509 is crimped with wires 5010. The setting of limiting blocks 507 and limiting grooves 508 here has the effect of limiting installation of contact frames 505, so that no matter how it moves during actual movement, part of the frame will be located inside the rectangular groove 503. This avoids the phenomenon that the contact frame 505 moves too much and completely leaves the rectangular groove 503 and is difficult to reset.

[0027] The contact surfaces of the positioning box 501, the base body 2, and the lightning strip body 4 are set as open structures. The outer side wall of the terminal block 509 is in contact with the outer side wall of the base body 2. This design ensures that when the terminal block 509 is installed inside the positioning box 501, its outer side wall can be tightly in contact with the outer side wall of the base body 2 while ensuring stable positioning, thereby ensuring the normal conductivity of the terminal block 509.

[0028] The contact bracket 505 is set in the shape of "[", and the outer wall of the top and bottom of the protruding foot at the bottom of the contact bracket 505 is set in an arc structure. The terminal block 509 is set in an arc structure all around. This design allows the terminal block 509 to be stably abutted and limited in the middle position of the two sets of contact brackets 505 during the upward movement. When the terminal block 509 is removed later, it can also be removed by pulling it directly.

[0029] The distance adjustment mechanism 6 includes a positioning mounting strip 601, an abutment strip 602, and an abutment groove 603. The positioning mounting strip 601 is fixedly installed on the outer side wall of the base body 2, and the abutment strip 602 is fixedly installed on the outer side wall of the positioning box 501. The top outer wall of the positioning mounting strip 601 is provided with an abutment groove 603 for the abutment strip 602 to be inserted and installed. The outer side wall of the positioning mounting strip 601 at the position of the abutment groove 603 is provided with a positioning threaded groove 604 at equal intervals. The outer side wall of the abutment strip 602 is provided with a mating threaded groove 605. Fastening bolts 606 are installed inside the positioning threaded groove 604 and the mating threaded groove 605. The setting of the abutment strip 602 and the abutment groove 603 here plays a preliminary limiting and supporting role for the installation of the positioning box 501.

[0030] The protective cover 7 includes a reinforcing support 701, a protective cover 702, a positioning strip 703, and a positioning slot 704. The reinforcing support 701 is fixedly installed on the bottom outer wall of the positioning mounting strip 601, and the side outer wall of the reinforcing support 701 is fixedly installed on the side outer wall of the base body 2. The protective cover 702 is installed over the outside of the positioning mounting strip 601 and the positioning box 501. The positioning strip 703 is fixedly installed on the bottom outer wall of the protective cover 702. The top outer wall of the reinforcing support 701 is correspondingly provided with a positioning slot 704 for the positioning strip 703 to engage. The protective cover 702 is provided here to protect the entire device from rain.

[0031] Working principle: Refer to the instruction manual. Figure 1 As shown in the attached diagram, the lightning strip body 4 in this device is a generalized concept. In actual application environments, many lightning strip bodies 4 need to be used side by side to ensure that the power can be transmitted to the ground normally.

[0032] See the attached instruction manual. Figure 5 -Appendix Figure 6 As shown, when installing the wire 5010, the two sets of positioning boxes 501 need to be adjusted to the appropriate support height according to the length of the wire 5010. During adjustment, the fastening bolt 606 needs to be completely unscrewed from the inside of the positioning thread groove 604, so that the contact strip 602 changes from the locked state to the movable state. Then, the positioning box 501 is pulled to adjust it to the appropriate support height. When the positioning box 501 moves, it will automatically drive the contact strip 602 to slide inside the contact groove 603. After moving to the designated position, the fastening bolt 606 is passed through the corresponding positioning thread groove 604 and screwed to the bottom of the mating thread groove 605. This completes the height adjustment process of the positioning box 501.

[0033] See the attached instruction manual. Figure 1 -Appendix Figure 4As shown, when it is necessary to install the terminal block 509 at the end of the wire 5010 into the positioning box 501, simply adjust the terminal block 509 to a suitable position and push it vertically upward into the placement slot 502. When the terminal block 509 abuts against the contact bracket 505 during movement, the contact bracket 505 automatically moves to the side under the squeezing action of the terminal block 509, providing a certain space for the contact bracket 505 to pass through. The movement of the contact bracket 505 will then automatically drive the limiting block 507 to slide inside the limiting groove 508. Simultaneously, the contact spring 506 is squeezed by the contact bracket 505 and... In the retracted state, when the terminal block 509 is fully moved upward and inserted into the middle position of the "["-shaped contact bracket 505, the reaction force generated by the compression of the contact spring 506 will push the contact bracket 505 to move in the opposite direction and limit the terminal block 509 to the middle position of the two sets of contact brackets 505. This completes the installation process of the terminal block 509. The subsequent disassembly process can be carried out by manually pulling the terminal block 509 downward. After the terminal block 509 is installed, the installation process of the wire 5010 is completed, and the connection and installation of the base body 2, the lightning rod body 3 and the lightning protection strip body 4 are completed.

[0034] See the attached instruction manual. Figure 7 As shown, after the terminal block 509 and wire 5010 are installed, the positioning clip 703 at the bottom of the protective cover 702 can be directly inserted into the positioning slot 704 at the corresponding position along the vertical downward direction. Thus, the protective cover 702 can achieve the effect of protecting the entire device through its sealing and protective function.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
