Abstract
The utility model discloses a power supply transmission device with a protective circuit, which comprises a power cord and a protective unit, wherein the power cord is provided with a ground wire and a live wire; the liver wire is provided with a preset position; and a first connecting point and a second connecting point are arranged at the preset position. The protective unit is provided with a first end point and a second end point; the first end point is electrically connected to the first connecting point; and the second end point is electrically connected to the second connecting point. Therefore, electric surging and all sporadic electromagnetic waves can be prevented.
Description
Technical field
The utility model refers to a kind of power delivery device with protective circuit especially relevant for a kind of power delivery device.
Background technology
Usually need to use power line in the daily life; Power line is the important media that connects between power supply and the electrical equipment; Electrical equipment is connected to power supply by power line, with the required electric energy of the work of obtaining.
General power line comprises live wire and ground wire; Power supply is returned from ground wire after entering electrical equipment from live wire again, has so just finished electric loop.Because power line is except supplying the transmission power supply; when the plug of power line one end is inserted on the socket of AC power; easily produce spark between the contact metal film of plug and socket inside; can produce various surge noises or burst electromagnetic wave; so general more valuable electrical equipment or precision instrument; the capital installs protection component (as fuse) additional on the path that power line connects, avoiding because of the surge noise or the electromagnetic input that happens suddenly, and cause the damage of electrical equipment or precision instrument.
But the cheap or easy electrical equipment of circuit for price general charged does not just have the so-called protection element on the path that power line connects, and therefore easily causes the easy electrical equipment of low price or circuit to damage.

For solving the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of power delivery device with protective circuit, can prevent the electromagnetic wave of surge and all bursts.
For reaching above-mentioned purpose of the present utility model, the power delivery device with protective circuit of the present utility model comprises: power line, have ground wire and live wire, and this live wire has the precalculated position, has first contact and second contact on this precalculated position; And protected location, having first end points and second end points, this first end points is electrically connected to this first contact, and this second end points is electrically connected to this second contact.
Described protected location can be transient voltage suppresser (transient voltage suppressor), gas discharge tube (gas discharge tube), high-voltage capacitance (high pressure electric capacity), transformer (transformer) or fuse (fuse).
Described power delivery device also comprises outer cladding, and this outer cladding coats this power line and this protected location.
Described power delivery device also comprises outer cladding and housing, and this outer cladding coats this power line, and this housing coats this protected location, and this housing is a cylinder.
Than prior art, the utlity model has following effect:
Because power delivery device of the present utility model has protected location, therefore can prevent the electromagnetic wave of surge and all bursts, to protect the electrical equipment of pegging graft with it.
