Technical field

The utility model relates to a kind of new type of plug.

Background technique

Medium of the plug as a kind of connecting circuit equipment and alternating current, structure is as depicted in figs. 1 and 2, two core power-line There are firewire L, zero curve N, three core power supply lines have firewire L, zero curve N, ground wire G；Above-mentioned firewire L, zero curve N or the one end ground wire G are used for Alternating current is connected, the other end is used for connecting circuit equipment.

However, these power supply lines only serve the effect of conduction electric current, i.e. alternating current is alternating current, is transmitted to going back for electrical equipment It is alternating current, in some occasions, electrical equipment uses direct current, at this point, often setting will hand over inside electrical equipment Galvanic electricity is converted into the current transfer device of direct current, and when work, the exchange on power supply line is electrically communicated to after electrical equipment again Direct current is converted by current transfer device for using；In this way, setting current transfer device will lead to inside electrical equipment The circuit of electrical equipment is excessively complicated, and occupies electrical equipment board design space, and even, work when increases circuit board Heat.

Utility model content

The utility model in order to overcome at least one of the drawbacks of the prior art described above (deficiency), provides a kind of insertion Head.

In order to solve the above technical problems, the technical solution of the utility model is as follows: a kind of new type of plug, comprising: firewire, zero Line, the first conducting wire, the second conducting wire and protection board；The protection board is provided with rectification circuit, wherein the firewire and zero curve connect Connect the alternating current arrival end of rectification circuit, the direct current outlet end of the first conducting wire and the second conducting wire connection rectification circuit.

When in use, firewire connects the alternating current of alternating current with zero curve to the plug, and alternating current becomes after rectification circuit It at direct current, is directly used in and is powered to electrical equipment, converted alternating current to directly in this way, can be saved inside electrical equipment The current transfer device of galvanic electricity, circuit greatly simplify, and reduce design space, decrease heat dissipation capacity.

In some embodiments, the rectification circuit is full-wave rectifying circuit or half-wave rectifying circuit.

It in some embodiments, further include varistor RV1, the both ends the varistor RV1 are connected to firewire And zero curve.It is excessive and damage the circuit in plug for preventing power grid from stirring voltage.

It in some embodiments, further include the first ground wire, for connecting the ground terminal of alternating current ground wire and electrical equipment.This Plug becomes three-prong plug, places electrical equipment shell electric leakage.

It in some embodiments, further include first capacitor YC1, the first capacitor YC1 is connected to zero curve and the first ground Between line.The electromagnetic interference of part electrical equipment can be filtered out.

It in some embodiments, further include that the second capacitor YC2, the second capacitor YC2 is connected to firewire and the first ground Between line.The electromagnetic interference of part electrical equipment can be filtered out.

It in some embodiments, further include fuse F1, the fuse F1 is connected in series in firewire.Fuse can be with Play the role of protecting plug circuit, when electric current is excessive, fuse is disconnected, to protect circuit from burning out.
