Abstract
The utility model discloses a tail triangular jack alternating-current power wire with a current indicating function, which comprises a three-phase plug, a connecting lead, a tail triangular jack and an indicating circuit, wherein the indicating circuit is mounted in the tail triangular jack and connected between a live wire end and a zero wire end of the tail triangular jack. The tail triangular jack alternating-current power wire is simple in structure and easy in realization, and whether current passes through the tail triangular jack alternating-current power wire or not and whether the tail triangular jack alternating-current power wire can be normally used or not can be judged visually and conveniently.
Description
Technical field
The utility model relates to a kind of afterbody product word jack AC power cord, relates in particular to a kind of afterbody product word jack AC power cord with electric current deixis.
Background technology
At present, a lot of electric equipment products all need to use afterbody product word jack AC power cord on the market, after opening circuit appears in power line inside, can cause the electric equipment products of connection to use, and existing afterbody product word jack AC power cord does not possess the electric current deixis on the market, under the condition that does not have test and maintenance equipment, whether have electric current pass through, can afterbody product word jack AC power cord normally be used if can't directly judge afterbody product word jack AC power cord.
The utility model content
The purpose of this utility model provides a kind of afterbody product word jack AC power cord with electric current deixis, whether have electric current pass through, can afterbody product word jack AC power cord normally be used by the electric current indicating device if can directly judge afterbody product word jack AC power cord.
The utility model adopts following technical proposals:
A kind of afterbody product word jack AC power cord with electric current deixis, comprise 3-phase plug, connect lead and afterbody product word jack, also comprise indicating circuit, indicating circuit is installed in the afterbody product word jack, and indicating circuit is connected between the live wire end and zero line side of afterbody product word jack.
Described indicating circuit comprises resistance and light-emitting diode, resistance and light-emitting diode series connection, and the luminous site of light-emitting diode protrudes in afterbody product word jack.
The utility model is simple in structure, is easy to realize whether can directly judge afterbody product word jack AC power cord by the electric current indicating device has electric current to pass through, and can afterbody product word jack AC power cord normally be used.
Description of drawings
Fig. 1 is an indicating circuit schematic diagram of the present utility model.
Embodiment
The utility model comprises 3-phase plug, connects lead, afterbody product word jack and indicating circuit.As shown in Figure 1, indicating circuit of the present utility model comprises light-emitting diode and resistance, the positive pole of light-emitting diode is connected to the live wire end (L) of afterbody product word jack by resistance, the negative pole of light-emitting diode connects the zero line side (N) of afterbody product word jack, and the luminous site of light-emitting diode protrudes in afterbody product word jack.When afterbody product word jack AC power cord has electric current to pass through, lumination of light emitting diode, prompting user afterbody product word jack AC power cord is in path, can normally use; When fracture appearred in the middle part of afterbody product word jack AC power cord, light-emitting diode did not work, and prompting user afterbody product word jack AC power cord is in off state, can't normally use.The utility model is simple in structure, is easy to realize, whether the afterbody product of judging word jack AC power cord that can intuitive and convenient has electric current to pass through, and can afterbody product word jack AC power cord normally be used.
