Please referring also to Fig. 2 and Fig. 3, Fig. 2 are a kind of electrical verification of electrical verification formula listening rod provided by the embodiment of the utility model
The structural schematic diagram of device, Fig. 3 are the left view of Fig. 2.The electroscopic device includes: current-limiting resistance 40 and neon tube 50；
The current-limiting resistance 40 listens needle main body 10 to connect by the first elongated end 60 with described；
The neon tube 50 is connect by the second elongated end 70 with the shell 20；
The current-limiting resistance 40 is connect with the neon tube 40.
First elongated end 60 and second elongated end 70 are that metal material is made, in a specific embodiment
In, first elongated end 60 and second elongated end 70 can be identical metal material, for example, first elongated end
60 and second elongated end 70 can be the metals such as stainless steel, copper.First elongated end 60 of metal material and described
Two elongated ends 70 can make electroscopic device preferably play a role, and not needing additional conducting wire makes the current-limiting resistance 40 and institute
Neon tube 50 is stated to play a role.
Further, it is connected between the current-limiting resistance 40 and the neon tube 50 by connecting rod 80, the connecting rod 80
It is made of metal material, in a specific embodiment, which can be with first elongated end 60 and described second

Stream is specifically arranged, and the utility model embodiment is not specifically limited herein.
Further, the neon tube 50 is identical as the neon tube effect of traditional electroscope, is provided to judge object under test
Whether leak electricity, when the neon tube 50 shines, it was demonstrated that object under test leakproof illustrates to be measured when the neon tube 50 does not shine
Object does not leak electricity.
In a specific embodiment, in order to make when electrical verification works, the hand of operator can easily hold the shell
20, then set column for the shell 20, thereon bottom opening, face closure of going to the bottom, and the bottom surface be located remotely from it is described
30 side of earpiece, in a specific embodiment, bottom surface is made of insulating materials, and specifically, which can be
Any insulating materials, the utility model are not specifically limited herein.
It should be noted that the "up" and "down" in above-mentioned " upper bottom surface " and " bottom surface " is at the electrical verification formula listening rod
Positional relationship when electrical verification working condition.
Further, the side of the shell 20 is made of metal material, when operator holds the metal shell, is tested
Voltage on object can listen needle main body 10, the current-limiting resistance 40, the neon tube 50, the shell 20 by described, then through people
Body access the earth, the neon tube 50 shines according to the difference of voltage or does not shine, thus indicate whether testee has electricity, from
And reach the function of electrical verification.
It should be noted that the reasons why bottom surface of the shell 20 is insulating materials are as follows: if under the shell 20
Bottom surface is metal material, then described to listen needle main body 10,20 bottom of the shell, human body and the earth to will form one complete to return
Road, and since the circuit does not have the current-limiting resistance 40, electric current can directly pass through the circuit, and without the current limliting
The circuit that resistance 40, the neon tube 50 form, at this moment, by the electric current of human body due to the effect meeting of no current-limiting resistance 40
Become larger, thus can cause damages to the life of human body, therefore, the most handy insulating materials of the bottom surface of the shell 20.
Further, since the light of the neon tube 50 sending is fainter, human eye is possible to not observe directly, therefore,
In the bottom of the shell 20, that is, guiding device is provided on insulating materials, the faint light for issuing the neon tube 50
Enhancing, so that human eye be enable to observe directly.
In a specific embodiment, which can be concave mirror, when the light that the neon tube 50 issues is radiated at
On the concave mirror, then through the concave mirror, the light that the neon tube 50 issues is gathered a bit, to reach enhancing light
Effect.
In a specific embodiment, which may be other devices that can be realized enhancing light, this reality
It is not specifically limited herein with novel.
In a specific embodiment, the earpiece 30 is made of insulating materials.The earpiece 30 is arranged to insulation to listen
Cylinder, can effectively completely cut off the influence of ambient noise, cause adverse effect to the normal detection of listening rod to prevent extraneous noise.
In a specific embodiment, the length for listening needle main body 10 is 110~150cm.The length can protect substantially
Electrical body can be touched in complicated narrow environment by demonstrate,proving the electrical verification formula listening rod, to complete electrical verification detection.
In a specific embodiment, the length of the electroscopic device is 8~10cm, which can enable the palm of people
It is enough to hold completely, facilitate and carries out electrical verification and audition operation.
The course of work of the audition of the electrical verification formula listening rod of the utility model embodiment are as follows:
When needing to carry out audition detection, insulation earpiece is tightly attached on object under test, so that sound can be by described
It listens needle main body 10 and the insulation earpiece to be transferred directly in human ear, completes audition detection.
The course of work of the electrical verification of the electrical verification formula listening rod of the utility model embodiment are as follows:
When needing to carry out electrical verification detection, needle main body 10 will be listened to be close to determinand described in one end opposite with insulation earpiece
Body, the voltage on object under test can listen needle main body 10, the current-limiting resistance 40, the neon tube 60, the shell 20 by described,
The earth is accessed through human body again, when the voltage of testee is more than 60 volts, then the neon tube 60 can shine, and instruction testee has
