DETAILED DESCRIPTION

[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] Example

[0025] A parallel connection structure of a lightning protection device includes a lap joint 10 and a base 1, wherein a connecting circuit component 5 is provided in the base 1, a first connecting portion 8 is provided on the connecting circuit component 5, a fixing component 6 is provided in the base 1, a cable of a target circuit can be inserted into the base 1 corresponding to a position between the first connecting portion 8 and the fixing component 6, the lap joint 10 can be inserted into the base 1 corresponding to a position between the first connecting portion 8 and the fixing component 6, the fixing component 6 is slidably matched with the base 1, and the fixing component 6 can be moved so that the cable and the lap joint 10 are both against the first connecting portion 8.

[0026] The lightning protection element in the existing lightning protection device is connected to the external target circuit through the connecting circuit component 5. The specific connecting circuit component 5 is respectively provided with an input line installation port and an output line installation port at both ends of the lightning protection element. During installation, the cable of the target circuit is overlapped with the connecting circuit component 5 from the input line installation port and the output line installation port through bolts 7 or structures such as snaps, so that the lightning protection element is connected to the target circuit. When two lightning protection devices need to be used in parallel, two overlap parts 10 extend into a base 1 through corresponding parallel plug interfaces, one is connected to the connecting circuit component 5 located between the lightning protection element and the input line installation port, and the other is connected to the connecting circuit component 5 located between the lightning protection element and the output line installation port. Then, the above-mentioned two overlap parts 10 are matched with another base 1 in the above-mentioned manner, and the two lightning protection devices that need to be connected in parallel are connected through the overlap parts 10 in the above-mentioned manner to realize the parallel connection between the two lightning protection devices.

[0027] The fixation between the cable of the target circuit and the connecting circuit component 5 needs to be achieved by bolts 7 or snaps, and the fixation between the connector 10 and the connecting circuit component 5 also needs to be achieved by bolts 7 or snaps. In order to reduce the above-mentioned two-step wiring and fixing process to one step, thereby improving the wiring operation efficiency, the connecting circuit component 5 of this scheme is provided with a first connecting part 8, and a fixing component 6 is also provided at the corresponding position. The fixing component 6 can be controlled by the operator. When performing the wiring operation, the cable of the target circuit is extended between the first connecting part 8 and the fixing component 6, and the connector 10 is extended between the first connecting part 8 and the fixing component 6. At this time, the relative position between the cable and the connector 10 and the lightning protection device is determined, and then the fixing component 6 is operated to make the fixing component 6 move to cooperate with the first connecting part 8, clamp the cable and the connector 10, so that the cable and the connector 10 are fixed to the connecting circuit component 5. Compared with the traditional solution that requires fixing the cables and the connecting piece 10 of the target circuit separately, which requires at least four wiring operations, the clamping structure formed between the fixing component 6 and the first connecting part 8 in this solution can cooperate with the cables and the connecting piece 10 of the target circuit at the same time, and after the fixing component 6 is moved, the cables and the connecting piece 10 of the target circuit are fixed to the connecting circuit component 5. Therefore, the parallel connection between the two lightning protection devices in this solution only requires four wiring operations.

[0028] In an optional embodiment, the fixing assembly 6 includes a bolt 7 and a frame structure 9, the frame structure 9 is slidably matched with the base 1, the head end 12 of the bolt 7 is located on the side of the copper sheet where the first connecting part 8 is located, and the foot end 13 of the bolt 7 passes through a through hole opened on the copper sheet and engages with the frame structure 9.

[0029] The connecting circuit component 5 has a copper sheet for forming a first connecting portion 8 at a corresponding position in the base 1. The copper sheet is fixedly arranged in the base 1. The bolt 7 passes through the copper sheet and engages with the frame structure 9. The frame structure 9 is constrained by the base 1. When the bolt 7 rotates, it can only move along the axial direction of the bolt 7. During the movement, it approaches the copper sheet and finally cooperates with the copper sheet for clamping.

[0030] In this solution, the frame structure 9 and the head end 12 of the bolt 7 are respectively located on both sides of the copper sheet, and a clamping structure is formed between the frame structure 9 and the copper sheet, and a clamping structure is formed between the head end 12 of the bolt 7 and the copper sheet.

[0031] In an optional embodiment, the copper sheet has a first plate segment 14 and a second plate segment 16 relative to each other, a first connecting segment 15 is provided between the first plate segment 14 and the second plate segment 16, the frame structure 9 has a third plate segment 20 and a fourth plate segment 18 relative to each other, a second connecting segment 19 is provided between the third plate segment 20 and the fourth plate segment 18, a through hole is provided on the first plate segment 14, and in the direction from the head end 12 to the foot end 13 of the bolt 7, the first plate segment 14, the third plate segment 20, the second plate segment 16 and the fourth plate segment 18 are arranged in sequence, a first gap 21 for matching the lap joint 10 is formed between the head end 12 of the bolt 7 and the first plate segment 14, the foot end 13 of the bolt 7 is engaged with the third plate segment 20, the third plate segment 20 is abutted against the second plate segment 16, and a second gap 17 for matching the cable is formed between the second plate segment 16 and the fourth plate segment 18.

[0032] The copper sheet is bent to form a first plate segment 14, a second plate segment 16 and two first connecting segments 15, the first plate segment 14 and the second plate segment 16 are arranged opposite to each other, the frame structure 9 is also bent by a conductive member to form a third plate segment 20, a fourth plate segment 18 and two second connecting segments 19, the third plate segment 20 and the fourth plate segment 18 are arranged opposite to each other, the second plate segment 16 passes through the frame structure 9, the bolt 7 is located on the side close to the first plate segment 14, and the frame structure is located on the side close to the second plate segment 16;

[0033] When the copper sheet and the frame structure 9 are not clamped, the frame structure 9 is located away from the bolt 7. At this time, the third plate segment 20 is located between the first plate segment 14 and the second plate segment 16, and abuts against the second plate segment 16. At this time, the second gap 17 between the fourth plate segment 18 and the second plate segment 16 is the largest in width, and the first gap 21 between the head end 12 of the bolt 7 and the first plate segment 14 is the largest in width;

[0034] When the bolt 7 is rotated, the bolt 7 drives the frame structure 9 to move toward the side close to the bolt 7. At this time, the third plate segment 20 is separated from the second plate segment 16 and moves toward the first plate segment 14. The fourth plate segment 18 gradually approaches the second plate segment 16 and finally abuts against the second plate segment 16, thereby clamping the cable between the second plate segment 16 and the fourth plate segment 18.

[0035] When the third plate segment 20 abuts against the second plate segment 16, the second plate segment 16 limits the displacement of the frame structure 9 in the direction from the head end 12 to the foot end 13 of the bolt 7. Since the relative position between the head end 12 of the bolt 7 and the frame structure 9 remains unchanged when the bolt 7 is not rotating, the frame structure 9 supports the bolt 7, thereby ensuring that there is a first gap 21 between the head end 12 of the bolt 7 and the first plate segment 14. When the bolt 7 is rotated, the distance between the head end 12 of the bolt 7 and the frame structure 9 is reduced. When the frame moves, the abutment between the second plate segment 16 and the frame structure 9 disappears. Therefore, the head end 12 of the bolt 7 gradually approaches the first plate segment 14, and the first gap 21 gradually decreases. Finally, the head end 12 of the bolt 7 abuts against the first plate segment 14, thereby clamping the lap joint 10 between the head end 12 of the bolt 7 and the first plate segment 14.

[0036] In an optional embodiment, a first mounting opening 2 and a second mounting opening 4 are provided on the base 1, and the cable of the target circuit can extend into the first gap 21 through the first mounting opening 2, and the lap joint 10 can extend into the second gap 17 through the second mounting opening 4. The two side end surfaces are relatively arranged on both sides of the base 1, and each side end surface can be fitted with the adjacent base 1. The second mounting opening 4 is provided on the side end surface, and a second connecting portion 11 is respectively provided at both ends of the lap joint 10, and the bolt 7 and the second connecting portion 11 can cooperate in a direction perpendicular to the side end surface.

[0037] The second installation opening 4 for inserting the lap joint 10 in this solution is provided on the side surface of the base 1. In the case of multiple connections, the side surfaces of two adjacent bases 1 are arranged opposite to each other, and the lap joint 10 is located between the two bases 1. The two ends of the lap joint 10 extend into the bases 1 on both sides through the corresponding second installation openings 4, and are connected to the corresponding connection circuits. The two bases 1 respectively constrain the lap joint 10 along the insertion direction of the lap joint 10 and the second installation openings 4. The constraining directions of the two ends of the lap joint 10 are opposite, that is, the two bases 1 clamp the lap joint 10. When one end is fixed, the lap joint 10 may swing, and the other end of the lap joint 10 is displaced. Since the other end extends into the base 1 through the second installation opening 4, the second installation opening 4 is provided on the side surface. The side end panel section at the inner wall of the second installation opening 4 restricts the further swing of the lap joint 10, thereby preventing the other end of the lap joint 10 from escaping from the second installation opening 4.

[0038] In an optional embodiment, the side end surfaces of two adjacent bases 1 are fitted together, the lap joint 10 is located between the first connection portions 8 of the two adjacent bases 1, and the two second connection portions 11 at both ends of the lap joint 10 are respectively matched with their respective corresponding first connection portions 8.

[0039] The spacing between the second connection parts 11 at both ends of the lap joint 10 is equal to the spacing between the two first connection parts 8 when the side end surfaces of the two bases 1 are fitted together. During actual installation, firstly, one end of the lap joint 10 is inserted into the second installation opening 4 of the corresponding base 1, so that the second connection part 11 at one end is matched with the first connection part 8 in the base 1, and then the other end is inserted into the second installation opening 4 of another base 1, and there is a spacing between the second connection part 11 at the other end and the corresponding first connection part 8, and finally the two bases 1 are brought closer to each other in a direction perpendicular to the side end surfaces until they fit together, and the second connection part 11 is moved inside the base 1 to match with the corresponding first connection part 8.

[0040] In an optional embodiment, the base 1 has an upper end surface, the upper end surface is located between the two side end surfaces, and an operation hole 3 is opened on the upper end surface, and the operation hole 3 corresponds to the head end 12 of the bolt 7.

[0041] The diameter of the operation hole 3 is smaller than the diameter of the head end 12 of the bolt 7 to prevent the bolt 7 from falling off through the operation hole 3. The operator can insert a tool such as a screwdriver into the base 1 through the operation hole 3 to rotate the bolt 7.

[0042] In an optional embodiment, a connecting hole is provided on the second connecting portion 11 , and a hole wall of the connecting hole is provided with a notch structure at a position corresponding to the bolt 7 , so that the bolt 7 can enter the connecting hole through the notch structure.

[0043] When the base 1 is installed on the mounting base, the lower end surface of the base 1 contacts the end surface of the mounting base, the upper end surface is arranged opposite to the lower end surface, and the side end surface, top end surface and bottom end surface of the base 1 are located between the upper end surface and the lower end surface.

[0044] The function of the bolt 7 is to position and fix the lap joint 10. The screw section of the bolt 7 extends to the through hole on the first plate section 14, corresponding to the second mounting opening 4. When the lap joint 10 extends into the base 1 from the second mounting opening 4, the second connecting portion 11 at the end of the lap joint 10 cooperates with the bolt 7. Specifically, a connecting hole is provided on the second connecting portion 11, and a notch structure is provided on the hole wall of the connecting hole at the position corresponding to the bolt 7, thereby forming a C-shaped structure. When the second connecting portion 11 approaches the bolt 7, the notch structure faces the bolt 7. As the second connecting portion 11 approaches, the bolt 7 enters the connecting hole through the notch structure and contacts the hole wall of the connecting hole, thereby determining the relative position between the lap joint 10 and the base 1. The abutment between the first plate section 14 and the second connecting portion 11 is then achieved through the abutment of the head end 12 of the bolt 7, thereby achieving electrical connection between the two.

[0045] In an optional embodiment, the two second installation openings 4 are arranged to overlap in a direction parallel to the side end surface.

[0046] In an optional embodiment, a baffle structure is provided in the second installation opening 4 , and the baffle structure is detachably matched with the base 1 .

[0047] The baffle structure is used to close the second installation opening 4 . When it is necessary to connect two power distribution devices, the baffle structure is taken out from the second installation opening 4 so that the bridging member 10 can cooperate with the second installation opening 4 .

[0048] Preferably, a knock-out hole structure is formed in the second mounting opening 4, so as to achieve closure in the base 1 and form a through-hole structure when necessary.

[0049] In an optional embodiment, the lightning protection device parallel connection structure further includes a lightning protection element, and the lightning protection element is detachably matched with the base 1.
