BACKGROUND OF THE INVENTION
The power socket has been a basic accessory for vehicles nowadays to meet the demand of drivers and passengers. There are increasing demands, apart from as a cigarette lighter, for other in-car electronic devices, CD or mobile charging kit, for example. Consequently, conventional power plugs have to be plugged into the cigarette lighter socket to acquire power.
The conventional power plug (cigar or cigarette lighter plug) extends a pole from its center and two stretching spring plates on the two sides of the external ring of the protruding pole as the other pole. The two poles are connected to the respective pole in the cigarette lighter socket to form a closed circuit. It is usually a direct current of 12V.
There is only one socket present in one vehicle at the moment. Therefore, the cigarette lighter is inserted into the socket for lighting a cigarette, and the further use of other electronic device, a handsfree mobile phone for example, can be only done by unplugging the cigarette lighter first and then the power plug of the electronic device may be inserted for power.

DETAILED DESCRIPTION OF THE INVENTION
With reference to FIGS. 1 to 3, the multi-accessory adaptor for vehicle comprises a power plug portion 1, and a socket portion 2.
The power plug portion 1 includes a cylindrical inserting rod 11, as shown in the figures, formed by connecting two semi-circular covers 11a and 11b face-to-face and a plastic cover 11c sealing the opening the connected covers. The size of the inserting rod 11 dimensionally corresponds to the socket of the cigarette lighter with a positive inserting pole 12 protruding from its front end cover 11c and two negative spring plates 13 disposed on its opposing sides and penetrating therethrough. The negative spring plates 13 can be retained within the aforementioned connector socket by their spring force, which is a conventional art and will not be discussed here further. The rear end of the inserting rod 11 is connected to an axial connection mechanism, as shown in the figures, comprising an axial connection plate 11d at the rear end of the inserting rod 11 with its external edge forming a plurality of engaging slots 11e on its side protruding laterally to form an axial tube 11f to be pivotally connected with the socket portion 2 and bended to a desired angle to suit the actual need.
The positive inserting pole 12 and a metal resilient body 14, a spring for example, are disposed with a fuse 5 therebetween to avoid overloading. Also, the metal resilient body 14 and one negative spring plate 13 are connected with a connection cord 16, respectively, penetrating through an axial tube 11f and in turn into the socket portion 2 to supply the power required.
The socket portion 2 is a hollow housing 21, as shown in the figures, comprising two housing cover 21a and 21b connected face-to-face, which is to axially connect the inserting rod 11 and to accommodate and retain at least two cylindrical sockets 24 described later.
The front end of the housing 21 is disposed with a pivoting mechanism to be axially connected to the front end of the inserting rod 11, wherein a slot 21d is disposed between the two axial walls 21c on the front center of the lower housing cover 21b for the insertion of the axial connection plate 11d and for the straddling of the lateral axial tube 11f onto the two axial slots 21e pre-formed on the two axial walls 21c, such that the whole the inserting rod 11 may move in an arcuate manner in front of the housing 21. Furthermore, to provide the inserting rod 11 with the functions of arresting and engaging when swinging, the rear of the two axial walls 21c are vertically disposed with a stop wall 21f and their front is protrudingly disposed with an engaging tenon 21g (shown in FIG. 3) to be engaged with one of the engaging slot 11e of the axial connection plate 11d so as to ensure the retainment and stability of the angle adjustment.
To provide the retainment of the positive plate 22 and the negative plate 23, the front and rear inner walls of the upper housing 21a and the lower housing 21b are formed to have a front inserting slot 21h and rear inserting slot 21i, respectively, to clampingly accommodate the positive plate 22 and the negative plate 23 so as to achieve retainment, wherein the positive plate 22 and the negative plate 23 are coupled with the positive and negative cords 16, respectively. Furthermore, the negative plate 23 on the rear end of the socket portion 2 are shaped to form a certain number of circular plate hole 231 corresponding to the required number of the cylindrical socket 24 for the insertion of the cylindrical socket 24.
As shown in the figures, for the embodiment of the cylindrical sockets 24, they may all be in the shape of short circular tube 241, or one of them is the existing cigarette lighter socket assembly 242 and the rest are short circular tube 241. Consequently, the design allows the insertion of different power plugs, or one is for the cigarette lighter and the rest are for other power plug. The flexible selection of the cylindrical socket 24 will not be discussed here further. In face, the rear opening of the short circular tube 241 protrudes to form a rim 241a, which can be clampingly accommodated within the rear opening 21j of the housing 21. On the other hand, the cigarette lighter socket assembly 242 may pass through the plate hole 231 and its connection portion 242 on its front end is connected to the through hole 221 pre-formed on the positive plate 22 so as to achieve a secured fastening.
Furthermore, the present invention further comprises a display device 25, wherein the upper housing 21a is shaped to form a through hole 21k for the insertion of a light channeling seat 251 in a bulb shape and then a light 252, a LED light or more specifically a multi-color LED light, is pressed to be retained in the light channeling seat 251 with its two legs 252a bended and straddled on the positive plate 22 and negative plate 23, respectively, such that the light 252 will be lit on when any one of the cylindrical sockets 24 is connected to a power plug for power, indicating that it is in a closed circuit state. Furthermore, the light display device 25 has a decorating effect as well.
With the aforementioned descriptions concerning the components and their relative configurations, the present invention is shown in FIG. 4 after assembly. When others articles in the vehicle may be hindered by the presence of the socket portion 2, the hindrance may be avoid by swinging the inserting rod 11, as show in FIGS. 5a to 5d, to render its engaging slot 11e selectively engaged with the engaging tenon 21g and thus to change the angle between the power plug portion 1 and the socket portion 2.
Consequently, with the implementation of the present invention, the power connection portion and the socket portion are integrated as one with their angular configuration may be adjusted, such that at least two cylindrical sockets may be securingly accommodated within the socket portion. Furthermore, the angle between the power plug portion and the socket portion may be adjusted so that the present invention can be placed at a desired angle to avoid hindering the driver or passengers and to conform to ergonomics. Furthermore, the present invention renders the cigarette lighter socket to supply power to both the cigarette lighter and other power plug so as to simplify the welding process and thus to reduce pollution, simply assembly process, and cut down manufacturing cost, which is indeed one of its kind.
While the invention has been described with reference to the a preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
