Abstract
The utility model provides a surge protector with a testing needle, wherein the technical problem which is to be solved is as follows: in order to test a voltage dependent resistor and a discharge tube in the surge protector, some of the surge protectors are provided with testing holes at the surfaces of lighting protection modules, when being used, a lead is inserted into a testing hole, the fish clamp of a test instrumentation clamps the other end of the lead; and some of the surge protectors are provided with testing contact points at the surfaces of the lighting protection modules, but the fish clamp of the test instrumentation can not clamp the testing contact point at the moment, and therefore, the test is inconvenient. The utility model has the main points that: a retractable type testing needle is arranged at the bottom of the lighting protection module in the surge protector, and the pedestal of the testing needle is connected to the connecting line between the voltage dependent resistor and the discharge tube in the lighting protection module. When being used, the retractable type testing needle protrudes the bottom of the lighting protection module, and therefore, the test is convenient; and after assembling the protector, the pinhead is retracted, and therefore, the normal use of the protector can not be influenced.
Description
Technical field
The utility model belongs to the special-purpose Surge Protector of lightning protection equipment one railway of railway signal, communication equipment; be installed in the signal box Machine Room; railway signals equipment power supply and signal transmssion line are carried out lightning protection; be the Surge Protector that has testing needle specifically, be applicable to on-the-spot independent test piezo-resistance in the surge protective device and discharge tube.
Background technology
The Surge Protector of railway use at present is a kind of thunderstorm electricity protective device, with the electronic product that uses on the protection train.It mainly is to be made of lightning-protection module and spill base etc., and copper strips electrode, piezo-resistance and discharge tube are arranged in the lightning-protection module.Be test piezo-resistance and discharge tube; the protector that has is provided with an instrument connection on the surface of its lightning-protection module; method of testing is to select suitable lead to insert in the instrument connection, and this lead is contacted with tested element, picks up the other end of this lead again with the fish of test instrumentation.The protector that also has is provided with a test contact on the surface of its lightning-protection module, but this moment, instrument fish folder can't be clamped test contact.Above-mentioned two kinds of methods are very inconvenient.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to provide a kind of Surge Protector that has testing needle, can greatly make things convenient for the independent test to piezo-resistance in the Surge Protector and discharge tube.
The purpose of this utility model has been achieved in that lightning-protection module and spill base, it is characterized in that: telescopic testing needle is installed in the bottom of lightning-protection module, and the base of testing needle is linked on the lightning-protection module interior piezo-resistance and the line between the discharge tube.Telescopic testing needle syringe needle protrudes in the bottom of lightning-protection module for stretching out state during no external force.When needs were tested separately piezo-resistance and discharge tube, the instrument fish is clamped telescopic testing needle and gets final product, and was very convenient; When lightning-protection module being inserted the spill base and be assembled into Surge Protector, the testing needle syringe needle is retracted in the needle stand by spill base top, does not influence the normal use of Surge Protector.
The utility model compared with prior art, its advantage is: when needing test, telescopic testing needle protrudes in the bottom of lightning-protection module, convenient test; After being assembled into protector, the syringe needle withdrawal does not influence the normal use of protector.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the side lead type surge protector schematic diagram.
Fig. 2 is the side lead type surge protector schematic diagram that has testing needle.
Embodiment
Referring to Fig. 1; side lead type surge protector is 22 li the side that 21, two copper strips electrodes 11 of a S shape socket are separately positioned on lightning-protection module 1 to be installed respectively at two lateral columns of spill base 2; in the time of in lightning-protection module inserts the spill base, 21 li of the sockets of copper strips electrode 11 insertion lateral columns.Incoming call enters socket 21 → copper strips electrode 11 → lightning-protection module 1 from the lateral column of spill base.The characteristics of side lead type surge protector are that its back panel wiring improves lightning protection effect greatly near zero.
Referring to Fig. 2, telescopic testing needle 5 is installed in the bottom of the lightning-protection module in the side lead type surge protector, and the base of testing needle is linked on the line of interior piezo-resistance of lightning-protection module and discharge tube.Telescopic testing needle syringe needle protrudes in the bottom of lightning-protection module for stretching out state during no external force.When needs were tested separately piezo-resistance and discharge tube, the instrument fish is clamped telescopic testing needle and gets final product, and was very convenient; When lightning-protection module being inserted base formation protector, the testing needle syringe needle is retracted in the needle stand by the base top, does not influence the normal use of side lead type surge protector.
Claims (2)
1, a kind of Surge Protector that has testing needle; lightning-protection module and spill base are arranged; the copper strips electrode is arranged in the lightning-protection module; it is characterized in that: telescopic testing needle is installed in the bottom of the lightning-protection module in the Surge Protector, and the base of testing needle is connected on the line of interior piezo-resistance of lightning-protection module and discharge tube.
2, according to the described Surge Protector that has testing needle of claim 1; it is characterized in that: a S shape socket respectively is installed in two lateral columns of spill base; two copper strips electrodes are separately positioned on the side of lightning-protection module; in the time of in lightning-protection module inserts the spill base, the copper strips electrode inserts in the socket of lateral column.
