Description

"ADAPTER WITH INTERCHANGEABLE PLUG BOARD" This invention relates to adapters for electrical outlets, and more particularly, to an adapter with an interchangeable plug board that can be easily interchanged for various typcs of receptacles.

Specifications of electrical plugs and receptacles are different in different countries.

Therefore, when one person travels to another country, the electrical plugs on his/her personal electrical appliances may not be able to fit into the receptacles OIL the electrical outlets in that country.

To solve the foregoing problem, an adapter as shown in FIG. 1 is provided. This adapter includes a covcr 1', a casing ', and a plug board 3', and conductive pieces (not shown). The cover 1' is formed with a plurality of insertion hloes 10' which allow various types of plugs to insert thereinto. The casing 2' has a lateral wall formed a slot 20' and insetting slit 21' and a bottom side formcd with a paji of cngaging slots 22'. When assem- bling the plug hoard 3 with the casing 2', the tongue-like picce 30', thc two insetting pieces 31', and the two engaging pieces 32' are fitted respectively in the slot 20', the insetting slits 21', and the engaging slots 22' in the casing 2'. The conductive frames arc mounted in the casing 2 for electrically connecting plug pin of a plug inserted into thc adapter through the insertion holes 10' with pins erected on the plug board 3'. This adapter allows the user to interchange the plug board 3 with another onc mounted with other type of plug pins. However, one drawback to this adapter is that detaching the plug board 3' is quite a laborious work to do, in that the disengaging of the engaging pieces 32' from the engaging slots 22' should be done by using, for example, a driver tool as sn assistant. This is quite incovenient for the user since the driver tool may not be always on hand with the user. Moreover, after frequent interchanging of the plug board 3', the engaging pieces 32' could break, which will cause the adapter unusable.

Further, the adapter is provided with three elastic pieces 4'. When the plug board 3' is attached to tle casing 2', the conductive pieces (not shown) arc electrically connected by way of these elastic pieces 4' to the fixed end 34' of the pins 33' on the plug board 3'. These elastic pieces 4', however, usually fall off position when the plug board 3' is detached from the casing 2' for replacement since they are floatingly mounted on the casing 2' without fastening means.

It is therefore a primary objecirve of the present invention to provide an adapter with an interchangeable plug board mounted with a plurality of plug pins that can be easily inter- changed with another on mounted with different plug pins for various types of receptacles.

It is another objective of the present invention to provide an adapter with an interchangeable plug board that are durable for frequent interchanging for vuious types of rtccp- tackles.

It is still another objective of the present invention to provide an adapter with an interchangeable plug board which is provided with secured elastic conductive pieces that will fall off from position when detaching the plug board from the casing.

In accordance with the foregoing and other objectives of the present invention, a new and improved adapter with an interchangeable plug board jq provided.

The adapter includes a casing, a plurality of conductive frames, a covcr, and a plug board. The casing has a bottom wall and four sidewalls formed on the bottom wall. Further, the casing is formed with fist insetting means including a plurality of slots or tongues on the bottom wail. In addition, an upright slide slot having an opening connected to the bottom wall is formed on one of the sidewalls. A rotaining means is slidably inset in the slide slot. The retaining means is a sliding piece having a top end formed with a stop tongue or a stop slot and which is lockablc at least at an uppcr position and a low position by mcans of the engagement of at least a protruded portion protruded from at least one side of the sliding piece with at leat two recesses formed on at least one sidewall of the slide slot, or alternatively of at least a recess formed on at least one side of the sliding piece with at least two protruded portions protruded from at least one side wall of the slide slot. The plug board has a base board and a plurality of plug pins erected on flic basc board. Further. the base board is formed with second insetting mcans including a plurality nf tongues or sloLs for forming a tongue-and-slot joint with the first insetting means on the casing, and, a stop slot or a stop longuc for receiving the stop tongue or stop slot of leo sliding piccc is formed near tlic rear edge of the base board. In addition, the conductive frames are mounted in the casing for electrically connecting plug prins of a plug inserted into the casing through insertion slots formed on the cover with die plug pins on the plug board.

The plug board is mounted in position on the casing by engaging the second insetting means on the plug board with the first insetting mcans on the casing and by shifting the sliding piece to the top position in which the stop tonguc is inserted in the stop slot on the plug board.

When the user wishes to replace the plug board with another one with a different type of plug pins, he/she needs just to push the sliding piece downwards, allowing the protruded portion on the sliding piece to be shifted from the engagement with upper recess to the engagement with the lower recess formed on the slidc slot, or allowing tbe recess on the sliding piece to be shifted. This withdraws the stop tongue from the stop slot on the back of the plug board. The plug board thus can be freely removed by the uscr for exchange.

The adaptcr can also be used as a plug. In such case, the casing is consisted of a top wall, a bottom wall and four sidewalls, arid a couple of conduct pieces arc mounted in die casing Further, an electrical cord is connected with the adapter through an insertion hole formed on Lhe top wail of the casing of the adapter.

The invention can be more fully understood by rending the following detailcd description of the preferred embodiments, with reference made to the accompanying drawings, wherein: FIG. 1 is an exploded perspective view of a conventional adapter for electrical outlets; FIG. 2 is an exploded perspective view of the adapteraccording to the present invention; FIG. 3 is a top view of the plug board of the adapter of FIG. 2; FIG. 4 is a perspective view of the adapter of FIG. 2 when assembled; FTC. 5 is a cross sectional 'vicw of the adapter of FIG. 4 cutting through the line A-A; and FIC. 6 is a cross sectional view of the adapter of P10. 4 cueing through the line @ B-@.
