Description
Technical field
The present invention relates to the electrical instrument technical field, especially relate to a kind of portable phase identification device.
Background technology
The phase identification device comprises core members, and core members is connected with display device such as 2 banana plugs and pilot lamp.Wherein, core members comprises computing and comparing element and necessary circuit.During use, 2 banana plugs are inserted respectively in the jack of a jack and power supply undetermined of operation power supply.If the phase place of the circuit in two jacks is identical, then pilot lamp does not work.Otherwise pilot lamp is bright.Like this, can judge the phase place of circuit very easily.But such phase identification device carries inconvenience, and has potential safety hazard.Therefore be necessary to improve.
Summary of the invention
Deficiency to above-mentioned prior art exists the purpose of this invention is to provide a kind of portable phase identification device, and it has convenient carrying.Further, it has characteristics safe in utilization.
To achieve these goals, the technical scheme that the present invention adopted is: portable phase identification device comprises core members; Core members is connected with 2 banana plugs; Said portable phase identification device comprises housing, and core members is fixed in the housing top, and lower housing portion is provided with the appearance wire casing.
Said housing is provided with buckle.
Said banana plug root is with elastic insulated cover.
The end of said banana plug is provided with the insulation head.
After adopting said structure, the present invention compares the advantage that is had with prior art and is: 1, easy to carry.The core members and the housing of portable phase identification device of the present invention are fixed as one, and housing is provided with the appearance wire casing.Like this, banana plug and connecting line thereof can be accommodated in and hold in the wire casing, are easy to carry.After the optimization, housing is provided with buckle, then can the phase identification device be fixed in positions such as waistband through this buckle.2, safe in utilization.The outside that is used for inserting the banana plug of jack is provided with elastic insulated cover, the end is provided with the insulation head, has avoided the too much exposed of banana plug metal, thereby safer.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the main TV structure synoptic diagram (broken section) of embodiments of the invention;
Fig. 2 is the left TV structure synoptic diagram of Fig. 1;
Fig. 3 is the A portion enlarged diagram of Fig. 1.
Among the figure: 10, housing, 11, buckle, 12, hold wire casing; 20, core members; 30, banana plug, 31, elastic insulated cover, 32, the insulation head; 40, pilot lamp.
Embodiment
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see that Fig. 1 is to shown in Figure 3: portable phase identification device comprises housing 10 and core members 20.Wherein, core members 20 comprises computing and comparing element and necessary circuit.Core members 20 is connected with display device such as 2 banana plugs 30 and pilot lamp 40.This core members 20 is fixed in housing 10 tops through modes such as foundings, and housing 10 bottoms are provided with appearance wire casing 12.Like this, when carrying the phase identification device, only need banana plug 30 and connecting line thereof be accommodated in to hold in the wire casing 12 to get final product.Further, housing 10 outsides are provided with buckle 11.Like this, can this phase identification device be fixed in waistband etc. through buckle 11 locates.
For fear of too much exposing of banana plug 30, increase the security of phase identification device, be with elastic insulated cover 31 on the metal of banana plug 30.The root that this elastic insulated cover 31 can be a rubber sleeve is connected with elastic device, and this elastic device is arranged in the root of banana plug 30.That is, in identification during phase place, elastic insulated cover 31 can be local as required or be all shunk in the root of banana plug 30.Like this; When banana plug 30 inserted in the jack, elastic insulated cover 31 shrank, and insert in the jack at the part metals position of banana plug 30; And the part that metal section and part exposes outside jack is wrapped by elastic insulated cover 31, has avoided the too much exposed of banana plug 30 metal.Further optimize, the end of banana plug 30 is provided with insulation 32.
The phase identification device is widely-used at present, and other structure is identical with prior art with principle, repeats no more here.
