Description
Technical field
The utility model belongs to cable detection technical field, more particularly to a kind of miniature examination electricity of detection circuit break-make
Device.
Background technology
In circuit detection process, examination electric appliance is more common tool, and whether detectable circuit has electricity, so that it is guaranteed that behaviour
Make the safety of personnel.Examination electric appliance at present on the market is similar, can determine the break-make situation of circuit well, but all deposit
In a drawback, can not carry.Sometimes it because leaving behind, and can not further work, cause unnecessary trouble.
Therefore, how above-mentioned technical problem to be overcome to become the technical issues of those skilled in the art are urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is just to provide a kind of miniature examination electric appliance of detection circuit break-make, can be fully solved above-mentioned existing
There is the shortcoming of technology.
The purpose of this utility model is realized by following technical proposals：
A kind of miniature examination electric appliance of detection circuit break-make, including housing, the housing include inner casing and shell, shell it is interior
Side wall is flexibly connected with the lateral wall formula of inner casing, and the shell is in tubbiness, and inner casing is integrally placed in shell, and inner casing is using saturating
Bright plastics are made, and described inner casing one end is provided with probe, other end connecting spring, and the spring is connected to the inner top surface of shell
On, shell is made of metal material, and is connected with neon tube and resistance, the neon tube and spring in the inner casing in turn from top to bottom
It is connected, the resistance is connected with probe.
Further, the outer casing top surface is provided with a ring buckle.Examination electric appliance can be hung over key by this design as key
It buckles, convenient for carrying.
Further, the tensile elongation of the spring is at least the length of inner casing.Be conducive to according to different use demands into
Row length adjustment.
Further, the shell is provided with end cap, and after inner casing retraction shell is interior, end cap is used to cover probe.Be conducive to
To good protective effect, either hang over and still carry in pocket with it, will not both damage clothing, examination electric appliance will not be damaged.
Further, the transparent plastic is PVC plastic.PVC plastic is widely used, of low cost.
Compared with prior art, the beneficial effects of the utility model are：Simple in structure, reasonable design is effective to reduce
The specification of examination electric appliance, convenient for carrying.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Reference numeral：Inner casing (1), shell (2), probe (3), spring (4), neon tube (5), resistance (6), ring buckle (7).
Specific embodiment
The utility model is further described with reference to specific embodiments and the drawings.
As shown in Figure 1, a kind of miniature examination electric appliance of detection circuit break-make, including housing, the housing includes shell 2 and interior
Shell 1.The shell 2 is in barrel-like structure, is made of metal material, the top surface of the shell 2 is provided with ring buckle 2, ring buckle 2
It can hang on key chain, convenient for carrying.The inner top surface of the shell 2 is connected with spring 4, and the other end of spring 4 is connected to
On the end face of inner casing 1, the other end of inner casing 1 is provided with probe 3, and the lateral wall of the inner casing 1 coordinates with the madial wall of shell 2
Formula is flexibly connected, such as is threadingly connected, and the mode that cooperation is slided can also be used, purpose is exactly can be by inner casing 1
It is fully retracted in shell 2, probe 3 is covered with the end cap of shell 2, so as to effectively reduce examination electric appliance size, convenient for putting in pocket
Or hang key chain, be worn at any time with, without as previous the problem of worrying to leave behind examination electric appliance during work.In the inner casing 1 successively
Neon tube 5 and resistance 6 are connected with, inner casing 1 is provided at both ends with metal connecting piece, and neon tube 5 is connected by metal connecting piece with spring 4,
Resistance 6 is connected by metal connecting piece with probe 3, and the inner casing 1 is made of PVC (polyvinyl chloride) transparent plastic, is being used
When, convenient for watching the light that neon tube 5 is sent out.
During detection, because spring 4 has certain tensile elongation, and the tensile elongation of this examination electric appliance spring 4
At least length of inner casing 1, so operating personnel can be adjusted according to actual conditions.Because shell 2 is made of metal material,
So holding shell 2 with hand, by probe 3 and cable contact, whether observation neon tube 5 shines.After use, probe is pinched
3, by 1 retraction shell 2 of inner casing, end cap is covered, is positioned in pocket or hangs on key chain, the next used time is further taken out come i.e.
It can.
The utility model is simple in structure, reasonable design, in a manner that inner casing 1 and shell 2 are connected, both effective contractings
The specification of small examination electric appliance, convenient for carrying, and does not influence to use, compact volume and convenience, suitable for promoting.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
