Abstract

The utility model discloses a power supply adaptor, which is mainly composed of a power supply adaptor main body and a transforming plug. The power supply adaptor main body comprises a shell, a circuit board and a socket; wherein, the circuit board and the socket are positioned in the shell; the shell comprises an upper surface cover and a lower surface cover; the lower surface cover is provided with a square shaped groove with a slot provided on one end; the slot is internally provided with concave surfaces; the transforming plug comprises a pin, a bolt and plug; the pin is arranged with a convex surface on surface; the convex surface on the pin matches with the concave surface in the slot. When the pin inserts into the slot, the convex surface on the pin is clamped by the concave surface in the slot and will sound, which indicates that the transforming plug has been assembled well; in addition, when in matching, the plug is connected with the power supply adaptor main body; the metal connecting piece connects the pin with the plug, thus making the power supply adaptor work normally. The product, after finished through matching, ensures the plug work normally without loosing.

Description

Power supply adaptor

Technical field

The utility model relates to a kind of power supply adaptor, refers in particular to a kind of power supply adaptor of Changeover plug.

Background technology

Power supply adaptor is the power supply conversion equipment of small portable electronic device and electronic apparatus, generally form, extensively be matched in the equipment such as mobile phone, walkman, switch, game machine, language playback device, notebook, cell phone by shell, circuit board and socket.

It is several that power adapter plug mainly contains city's plug of city's plug of city's plug, Australian Standard of city's plug, the European standard of city's plug, the British Standard of Unite States Standard and Chinese Industrial Standards (CIS).In order to be applicable to above-mentioned several standard, the practitioner with adapter that can changeover plug as its R﹠D direction.

The utility model content

The purpose of this utility model mainly is to provide a kind of power supply adaptor of Changeover plug, and it adopts IEC320 standard input interface, and plug and power supply adaptor that can each is national perfectly link together.

In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of power supply adaptor, and it is made up of power supply adaptor main body and changeover plug; Its changeover plug is provided with convex surface, and the power supply adaptor main body comprises shell, circuit board and socket; Circuit board and socket are located in the shell; Shell comprises capping and following capping; Following capping is provided with square groove, is provided with slot at an end of square groove, slot inside be provided with latch on the concave surface that cooperates with it of convex surface.

Described power supply adaptor, its described changeover plug comprises pin, latch, plug; Latch surface is provided with convex surface; Concave surface in convex surface on the latch and the slot matches.

After adopting said structure, when the latch on the plug is inserted slot, when the convex surface above the latch is blocked by the concave surface of slot the inside, can send a sound, show that the plug assembling puts in place; In addition, after working good, plug is connected with the power supply adaptor main body, and metal connecting piece is connected various countries' pin with plug, can make the power supply adaptor operate as normal; This product, after it is finished by square groove, slot, latch, concave surface and convex surface cooperation, the assurance plug during normal use can not cause and pitch, and this product is easy to use, is easy to carry, the profile fineness, with low cost, the plug that this power supply adaptor not only can be used U.S.'s city's electric standard also can use city's plug of standards such as China, Britain, European Union, Australia as the power supply adaptor main body as the power supply adaptor main body, the real global general-use of realizing, the needs of suitable consumption market.

Embodiment

Please refer to shown in Fig. 1 to 5, it discloses a kind of power supply adaptor, and it is made up of power supply adaptor main body 1 and changeover plug 2; Wherein:

Power supply adaptor main body 1 comprises shell 11, socket 12 and circuit board 13, and socket 12 and circuit board 13 are located in the shell 11;

Shell 11 comprises capping 112 and following capping 111;

Following capping 111 is provided with square groove 113 and slot 116, the concave surface 115 in the slot 116;

Changeover plug 2 comprises convex surface 211, latch 212, pin 213, the plug 214 on the latch;

After adopting said structure, when the latch on the changeover plug 2 212 is inserted slot 116, when the convex surface 211 above the latch 212 is blocked by the concave surface 115 of slot 116 the insides, can send a sound, show that changeover plug 2 assemblings put in place; In addition, plug 214 cooperates with socket 12, can make the power supply adaptor operate as normal; This product, after it was finished by square groove 113, slot 116, latch 212, concave surface 115 and convex surface 211 cooperations, assurance plug 2 during normal use can not cause and pitch; This product is easy to use, be easy to carry, the profile fineness, with low cost, this power supply adaptor not only can use the plug of U.S.'s city's electric standard as the power supply adaptor main body, also the city's plug that can use standards such as China, Britain, European Union, Australia is really realized global general-use as the power supply adaptor main body, the needs of suitable consumption market.
