Removable power supply transformer
Technical field
The utility model refers to a kind of removable power supply transformer especially about a kind of power transformer, and it can change the plug kenel according to user's needs, and it generally should be under the jurisdiction of the technical field category of power transformer.
Background technology
General existing power transformer, mainly be the voltage (60Hz that to be supplied with, 110~115V) change and adjust, use for circuit so as to exporting different voltage or the electric currents of many groups, it mainly is provided with a socket and a plug, in socket, be installed with a transformation module for changing voltage or electric current, and plug forms in a side of socket in order in the jack that inserts power supply;
Though the existing power supply transformer can provide the effect of a changing voltage or electric current, but this plug sets firmly a side that forms in socket, therefore, when the jack kenel of power supply (as 2 cellular types, when the jack of 3 cellular types or splayed etc.) changing, then must buy the power transformer that is consistent with this jack kenel uses, not only can increase the cost of use, and a plurality of power transformers also can increase the inconvenience of taking in, therefore, industry has a kind of removable power transformer in addition at present, it mainly is that a side in socket forms an engagement groove, and be formed with a board in the end that plug combines with socket, see through the mode that board combines with engagement groove, plug is removably combined with socket;
Yet, though the mode that existing removable power supply transformer can combine with the socket engagement groove by the plug board, the user can be changed according to the kenel of supply hub, but existing removable power supply transformer, because the mode that only matches with engagement groove by board between plug and socket is carried out combination, therefore easily when pulling out power transformer, plug and socket take place to be separated and to be inserted in situation on the supply hub, so, when pulling out plug, be easy to generate the phenomenon of electric shock, so can produce the doubt on the safety in use, in addition improvements are really arranged.
The utility model content
Therefore, the inventor is promptly at the disappearance and the deficiency of existing removable power supply transformer structure, and is special through continuous research and experiment, develops finally a kind of the utility model that can improve existing disappearance.
The utility model is a kind of removable power supply transformer, it is the structural arrangements mode by simplifying mainly, plug not only can be separated with socket, and in conjunction with the time also can firmly set firmly combination mutually with socket, and then constitute a kind of can be firmly in conjunction with, change the removable power supply transformer person of plug and safe handling.
For achieving the above object, the utility model provides a kind of removable power supply transformer, and it is provided with a socket and a plug, wherein:
This socket is concaved with an engagement groove inwardly in an end place of end face, and socket is provided with the drawing piece of going up warpage one day in the engagement groove bottom surface, and socket convexes with several cards in the internal face of engagement groove and establishes in addition; And
This plug is and removably combines with socket and be provided with a cover plate, a combined block and several power supply terminals, wherein this cover plate is covered on socket engagement groove top, and the combined block of plug is convexly equipped with a side that forms in cover plate, and be provided with one in the center and can block the hole clipping of establishing mutually with the socket drawing piece, in addition combined block is concaved with several and establishes the card that piece combines with the socket card respectively and establish groove on outer peripheral edges, and each power supply terminal combines with the side that lid differs from combined block, and plug runs through in the side that cover plate is provided with power supply terminal and is provided with a through hole that communicates with the combined block hole clipping.
Preferably, this engagement groove slightly is a square structure, and this cover plate is a shape that can be covered on the socket engagement groove.
Preferably, this socket is provided with a perforation in running through near the engagement groove bottom surface of drawing piece, and drawing piece is stretched in the perforation.
Preferably, this socket is a pedestal that slightly is rectangle.
Preferably, this perforation slightly is a square structure.
By above-mentioned technological means, the configuration mode that the removable power supply transformer of the utility model can fasten by plug hole clipping and socket drawing piece, plug can firmly be combined with socket, can effectively avoid when pulling out power transformer, plug and socket take place to be separated and to be inserted in situation on the supply hub, and then avoid the phenomenon that generation is got an electric shock when pulling out plug, and then provide a removable power supply transformer person that can use safely.

Embodiment
The utility model mainly provides a kind of removable power supply transformer, please cooperate referring to shown in Fig. 1,2, by finding out among the figure that the removable power supply transformer of the utility model mainly is provided with a socket 10 and a plug 20, wherein:
This socket 10 is a pedestal that slightly is rectangle, this socket 10 is concaved with an engagement groove that slightly is square 11 inwardly in an end place of end face, this socket 10 runs through in the center of engagement groove 11 bottom surfaces and is provided with a perforation that slightly is square 12, and socket 10 is provided with one and is stretched in the perforation 12 and the drawing piece 13 of warpage up, and socket 10 convexes with several cards in the internal face of engagement groove 11 and establishes piece 14 in addition; And
This plug 20 is and removably combines with socket 10 and be provided with a cover plate 21, one combined block 22 and several power supply terminals 23, wherein this cover plate 21 is a shape that can be covered on socket 10 engagement grooves 11 tops, and the combined block 22 of plug 20 is convexly equipped with a side that forms in cover plate 21, and be provided with one in the center and can block the hole clipping 221 of establishing mutually with socket 10 drawing pieces 13, in addition combined block 22 is concaved with several and establishes the card that piece 14 combines with socket 10 cards respectively and establish groove 222 on outer peripheral edges, and each power supply terminal 23 combines with the side that lid 21 differs from combined block 22, and plug 20 runs through in the side that cover plate 21 is provided with power supply terminal 23 and is provided with a through hole 24 that communicates with combined block 22 hole clippings 221.
