Abstract
The utility model discloses a power source lightning protection device. The power source lightning protection device comprises a PCB (2) mounting in a casing (1), a discharging tube (3) mounted on the PCB (2)and a stud (4) connected with the casing (1) and further comprises a grounding wire (5), wherein one end of the grounding wire is welded on a grounding hole (8) arranged on the PCB (2), the other end of the grounding wire is provided with a copper ear (7), and the copper ear (7) is connected with the stud (4) through a screw. The power source lightning protection device can avoid repeatedly dismounting a grounding device during a production overpressure resistance test and improves production efficiency.
Description
Technical field
Utility model relates to a kind of lightning protection device for electric power.
Background technology
Existing lightning Protection Design generally adopts discharge tube direct ground connection to realize.A kind of existing lightning protection device for electric power as shown in Figure 1, comprise the pcb board 2 that is installed in the shell 1, one discharge tube 3 is installed on this pcb board 2, and is provided with an earthing screw hole 9 that is connected with discharge tube 3, use screw that pcb board is connected with double-screw bolt 4 on being installed in shell 1.Because screw 10 contacts with shell double-screw bolt 4, is equivalent to discharge tube 3 ground connection.Owing to before carrying out withstand voltage Insulation test, need artificially to disconnect discharge tube, and withstand voltage Insulation test needs so repeatedly, to influence production efficiency with in the welding of discharge tube breaking part after finishing.And when welding the tin sweat(ing) that produces cause easily between the components and parts that short circuit or welding damage the pcb board material, exist hidden danger of quality.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the above-mentioned prior art, and a kind of lightning protection device for electric power is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of lightning protection device for electric power, comprise in the enclosure pcb board of installation, be installed in the discharge tube on this pcb board, the double-screw bolt that is connected with shell, wherein, also comprise an earth connection, this earth connection one end is welded on the ground hole that arranges on this pcb board, and another end is provided with the copper ear, and the copper ear is connected with this double-screw bolt by screw.
Compared with prior art, the utlity model has following advantage: can avoid repeated disassembled and assembled discharge tube when producing voltage-withstand test, enhance productivity, solve the hidden danger of quality that human factor causes product to the full extent.
Description of drawings
Fig. 1 is the schematic diagram of lightning protection device for electric power in the prior art.
Fig. 2 is the front view of the utility model lightning protection device for electric power.
Fig. 3 is the side sectional view of utility model lightning protection device for electric power.
Fig. 4 is the schematic diagram of utility model lightning protection device for electric power.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Shown in Fig. 2 to 4, the lightning protection device for electric power that the utility model proposes comprises: be installed in pcb board 2 in the shell 1, be installed in the discharge tube 3 on this pcb board 2, the double-screw bolt 4 that is connected with this shell 1, wherein, also comprise an earth connection 5, this earth connection one end naked copper partly is welded on this pcb board (2) and goes up on the ground hole (8) that arranges, and another end is provided with copper ear (7), and copper ear (7) is connected with this double-screw bolt (4) by screw.
When lightning protection device for electric power was carried out withstand voltage Insulation test, copper ear 7 was not connected with double-screw bolt 4, and both discharge tube 3 did not directly link to each other with ground hole 8, and it is unearthed also just to be equivalent to discharge tube 3, can directly carry out withstand voltage Insulation test.Behind the withstand voltage Insulation test, again copper ear 7 and double-screw bolt 4 are linked together, earth connection 5 ground connection that links to each other with double-screw bolt 4 on this moment ground hole, and discharge tube 3 links to each other with ground hole, also just has been equivalent to discharge tube 3 ground connection.
The lightning protection device for electric power of the utility model design is by the transition of wire rod, and the repeated disassembled and assembled discharge tube is enhanced productivity in the time of can avoiding producing voltage-withstand test, can solve the hidden danger of quality that human factor causes product to the full extent.
Claims (1)
1. lightning protection device for electric power, comprise the pcb board (2) that is installed in the shell (1), be installed in the discharge tube (3) on this pcb board (2), the double-screw bolt (4) that is connected with this shell (1), it is characterized in that: also comprise an earth connection (5), described earth connection one end is welded on described pcb board (2) and goes up on the ground hole (8) that arranges, another end is provided with copper ear (7), and described copper ear (7) is connected with described double-screw bolt (4) by screw.
