Abstract
The utility model discloses an earthing mode signal arrester and relates to a surge protector. The earthing mode signal arrester includes a circuit board; an input end consisting of two pieces of signal lines and an output end connected with equipment are arranged on the circuit board; a first level discharge element and three second level discharge elements are also arranged between the input end and the output end; wherein one second level discharge element is connected with a main loop in parallel; an earthing wire is welded between the two pieces of signal lines of the input end connected with the first level discharge element; and the other two second level discharge elements are connected with the earthing wire. The earthing mode signal arrester adopts the three-bit connecting terminal mode of two pieces of signal lines and one piece of earthing wire; and the discharge elements are directly welded with the terminals; therefore, the resistance of a branch discharge is reduced and the limited voltage caused by lightning induction is effectively reduced. Moreover, the field installation is convenient, and product waste can not be caused, thus greatly improving the using rate of products.
Description
Technical field
The utility model relates to surge protective device, particularly a kind of ground connection mode signal lightning arrester.
Background technology
Ground connection is the most important link of lightning-protecting engineering, no matter be direct lightning strike, induction thunder or other forms of thunder, finally all is that lightning current is sent into the earth.Therefore, there is not reasonable and good earthing device not take shelter from the thunder reliably.Earth resistance is more little, and the stream that looses is just fast more, and the object high potential retention time of being struck by lightning is just short more, and is dangerous just more little.
Common product all is to increase an earth lead in the shell outer end at present, and earth lead one end is welded on the circuit board, and an other end is drawn by cable-through hole, is connected with the earth connection of earth mat.There are following problems in such earth connection: the earth connection of a. product bothered with being connected very of earth mat earth connection, need be now with electric iron with two wire bonds together or with screw with two conductor compression jointings together.Install very inconvenient at the scene; B. according to code requirement, the earth connection of lightning arrester is short more good more, and this earth connection has increased the length of earth connection virtually, and the length increase of earth connection can bring the rising of deboost, and the rising meeting of deboost brings serious destruction to subscriber equipment; C. because earth connection one end is welded on the circuit board, when external earth connection connects, in case be welded on the circuit board that ground connection comes off or loosening, this product will be scrapped so.The utility model content
The purpose of this utility model is: a kind of easy for installation, ground connection mode signal lightning arrester that can reduce deboost, increase the service life is provided.
The technical solution of the utility model is as follows:
A kind of ground connection mode signal lightning arrester, comprise wiring board, described wiring board is provided with input of being made up of two holding wires and the output that is connected with equipment, comprise a first order arresting element and three second level arresting elements between described input and the output, one of them second level arresting element is in parallel with major loop, it is characterized in that, weld earth connection between two holding wires of the input that described first order arresting element connects, described two second level arresting elements in addition connect earth connection.
Outstanding advantage of the present utility model is:
The utility model adopts 3 binding post patterns of two holding wires and an earth connection, direct and the terminal welding of arresting element, reduced the resistance of discharge paths, reduced the deboost that lightning induction causes effectively, can also make on-the-spot easy for installation like this, can not cause scrapping of product, improve the use qualification rate of product greatly.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of prior art lightning arrester.
Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model schematic diagram.
Embodiment
As shown in Figure 3, a kind of ground connection mode signal lightning arrester, comprise wiring board, wiring board is provided with input of being made up of two holding wires 1,2 and the output that is connected with equipment, comprise a first order arresting element 4 and three second level arresting elements 5 between described input and the output, one of them second level arresting element 5 is connected with two signals, 1,2 lines, welding earth connection 3 between described two holding wires 1,2 of putting the input that first order electric device 4 connects, described two second level arresting elements 5 in addition connect earth connections 3.
Arresting element 5 direct levels or be arranged vertically in the circuit board.
The utility model adopts 3 binding post patterns, can effectively solve this signal arrester ground problem.And the arresting element of inside modules can be directly and the terminal welding, can shorten the resistance of discharge paths like this, effectively reduces the deboost that lightning induction causes.Surge Protector is serially connected with the protected front equipment end of system, and when transmission line suffered lightning induction, lightning current was by the thunder and lightning branch road of the protector the earth of releasing, and lightning overvoltage is clamped in the voltage range that equipment allows, thereby has guaranteed the safety of equipment.
