Definitions

the present invention relates to an AC power plug assembly adapted for various foreign countries, particularly to an AC power plug assembly for electric devices such as AC power adapter, AC/DC converter, battery charger, and so on which are integrally combined with an AC plug.
AC plugs currently used over the world have not yet been standardized to a single shape. Accordingly, it is required to use a specially made plug adapter or exchange plug shape when electric devices commonly used in Japan are used or sold in various foreign countries especially in Europe.
AC plug integrally formed electric devices such as battery chargers have been required to reconstruct their plug element so as to fit the plug shape with that of plug socket used in their destination.
a pair of pins or blades 2, 2 has been integrally disposed in a housing 1 of electric device by a molding process.
a pair of plug pins 2, 2 should be previously inserted in a metal mold for molding the housing 1.
the shape, dimension, and angle of the pair of plug pins 2, 2 may vary in accordance with the plug socket used in destination. This means the manufacturing process of such insert-molded plug will complicate. That is, the cost of the electric device having such insert-molded plug will rise.
Another object of the present invention is to provide an improved AC plug assembly which can be easily fit to any shapes of plug sockets used over the world.
Further object of the present invention is to provide an improved AC plug assembly which has a sufficient mechanical strength after assembled.
the present invention provides an improved AC plug assembly adapted for a housing of electric device made of insulating plastic material which is provided with two openings.
This plug assembly comprises a pin block including (a) a connecting member and (b) a pair of plug pins integrally formed in the connecting member to permit the plug pins to be protruded out of the housing through the openings formed in the housing.
the pin block of the plug assembly is preferably fixed to the housing by engaging between a first engaging means formed in the connecting member in the vicinity of the base portion of the plug pin and a second engaging means formed in the opening of the housing.
the first engaging means is preferably composed of a flange and an annular groove.
the second engaging means is preferably formed in an annular internal edge. These annular groove and annular internal edge can be fit with each other to prevent the plug pins from falling off.
the connecting member is fixed securely to the housing through another fixing means such as a screw bolt.
the plug assembly according to the present invention uses a previously assembled single member, the pin block, composed of the plug pins and the connecting member, this plug assembly can be used as a common part to the other type housings of different electric devices through a simple fitting manner without complicated molding steps.
various pin blocks having different pin configurations can be easily fabricated in accordance with desired destinations and thus fabricated pin blocks can be fit to the same housing of electric device.
the pin block of the plug assembly according to the present invention is fixed to the housing by engaging between the annular groove in the connecting member in the vicinity of the base portion of the plug pin and the annular internal edge formed in the opening surface of the housing. Since this engagement is firmly performed, the connecting member is prevented from subjecting to the bending force owing to the impact along the axis of the plug pin. In order to achieve this engagement, the pin block is forcibly inserted into the two openings from the inside of the housing. This engagement is assisted by any irreversible mechanism such as tapered edge formed in the flange of the first engaging means.
the screw member also assists the connecting member of the plug assembly in fixing with respect to the housing.
the plug assembly can be firmly fixed to the housing by the combination of these two fixing means.
a plug assembly which is adapted for a housing 10 of electric device such as a battery charger.
the housing 10 is made of any insulating plastics, synthetic resins or the like by molding.
the housing 10 is provided with two openings 11, 11 for plug pins 21, 21.
Fig. 2 shows a pin block 20 composed of these two plug pins 21, 21 formed in a rod shape made of conductive metal material, and a connecting member 22 made of insulating plastic, or synthetic resin material. These two plug pins 21, 21 are previously set in a metal mold for molding the connecting member 22 before injecting the melted synthetic resin into the mold.
the connecting member 22 is formed in a bridge shape whose both ends respectively contain the plug pins 21, 21 which are arranged at a predetermined angle. In the vicinity of each base portion of the plug pins 21, 21, 21, the connecting member 22 further includes a first engaging means composed of a flange 23 and an annular groove 24. The flange 23 is further provided with a tapered front edge. In this shown embodiment, the connecting member 22 is additionally formed with a center bore for receiving a fixing means 12 such as a screw bolt.
each of the openings 11, 11 formed in the housing 11 is also provided with a second engaging means whose shape corresponds to that of the first engaging means.
the second engaging means is formed in an annular internal edge 13.
the plug pins 21, 21 are respectively inserted into the openings 11, 11 from the inside of the housing 10 and then the flanges 23, 23 of the connecting member 22 are pressed into the annular internal edges 13, 13.
the tapered front edge facilitates the flange 23 to be passed through the annular internal edge 13 formed in the opening 11 and allows the annular groove 24 of the connecting member 22 and the annular internal edge 13 to be easily engaged.
the pin block 20 is kept in its predetermined position as shown in Fig. 1. Further, the screw bolt 12 is screwed in the housing 10 so that the connecting member 22 can be firmly fixed to the housing 10.
the above described embodiment shows two fixing means of the engagement defined between the first engaging means 23, 24 formed in the base portion of the plug pin 21 and the second engaging means 13 formed in the opening surface of the housing 10, and the fixing means 12 such as the screw bolt, one of these fixing means may be omitted or the fixing means 12 may be selected from more simple fixing means such as snap ring,resilient locking mechanism, chemical bonding, thermal bonding and so on.
the plug assembly according to the present invention uses a previously assembled single member, that is the pin block, composed of the plug pins and the connecting member, and therefore this pin block can be used as a common part to the other type housings of different electric devices through a simple fitting manner without complicated molding steps.
various pin blocks having different configurations can be easily fabricated in accordance with desired destinations and thus fabricated plug assembly can be fit to the same housing of electric device.
This assembly can realize various types of electric device having fine modified plug shapes depending on desired plug socket shape at a low cost.
the pin block of the plug assembly according to the present invention is fixed to the housing by engaging between the annular groove in the external surface of the base portion of the plug pin and the annular internal edge formed in the opening surface of the housing. Since this engagement is firmly performed, the connecting member is prevented from subjecting to bending force owing to the external impact along the axis of the plug pin.
the pin block of this plug assembly is forcibly inserted into the two openings from the inside of the housing to perform this engagement. Further, this engagement can be kept by the screw bolt which assists the connecting member of the plug assembly in fixing with respect to the housing. As a result, the pin block of the plug assembly can be firmly fixed to the housing by the combination of these two fixing means.
