The connector adapter is one of the essential items when traveling abroad. It provides the basic connector switching function of electrical appliances, so that the connectors and sockets of different specifications can be electrically connected to power the electrical appliances. Reference patents and their products are commercially available. Some of them belong to the applicant, as described below.

Taiwan Patent No. 430166 discloses a universal socket having a structure that can be quickly assembled by specification. According to this, a socket having different insertion ports of various countries can be coupled onto a socket anchor seat having at least one connection port formed thereon. This allows a socket suitable for a particular country to be quickly assembled and connected to a power source. The main component of the socket is a base bottom with a metal pin connecting member on the top and a screw hole or jack. Each metal pin connecting member is coupled to two conductive brackets and one grounding bracket in the socket. The screw hole can be quickly engaged with the conductive member having the threaded portion so that it can be energized into the socket. Moreover, the socket can be fastened in the socket anchor seat consisting of a base and an upper case having at least one coupling port. The upper case corresponding to the base and the coupling port has one or more clipping terminals that can be integrally fastened to the conductive member provided on the bottom of the socket. The clipping terminal is fixed in a plurality of anchor frame edges formed on the base. A safety spacer is interposed between the base and the upper case. The safety spacer and the clipping terminal each have openings corresponding to each other such that the conductive member extends through the opening to the bottom of the socket. With this structure, sockets having different ports of various countries are fixed to each coupling port of the socket anchor sheet, so that the conductive member on the socket bottom extends through the opening of the safety spacer and is fastened to the clipping terminal provided in the base. Integrated, power is applied to the socket to support various types of power connectors. The socket also has resilient clips on both sides so that the socket can be quickly engaged to each engagement port of the socket anchor seat. The safety spacer is configured to provide safety protection by preventing voltage applied clipping terminals from contacting when the socket is not yet connected.

Taiwan Patent No. 445671 discloses a universal adapter having a rapidly replaceable insertion port face panel. The insertion port face panel is located in the socket or adapter having a universal insertion port. The insertion port face panel can be configured to have different insertion ports according to various countries, and can be quickly replaced to form a socket or an adapter having the required insertion port. The face panel of the socket or adapter has preset insertion ports of different specifications in different countries to accept the connector. The socket or adapter has a frame having a flange of a predetermined height around the insertion port. Grooves are formed in the frame to be coupled to face panels of different insertion ports. The face panel has one or more elastic supports formed on its bottom and inserted into one insertion port for fixation when installed in the groove. As a result, an insertion port conforming to one specification is formed. The insertion port face panel can be removed and replaced with another insertion port face panel with another insertion port, allowing for quick replacement as required. Thus, the socket or adapter can be quickly changed to have an insertion port in accordance with the required specifications.

Taiwan Patent No. 456634 discloses a universal adapter with a simple structure based on the German connector specification. The adapter includes a face panel and a body integrally formed by injection molding. The adapter includes a housing portion having a conventional conductive rack on each side thereof. In the centrally located housing portion there is a grounding rack formed by a single clipping board. The body is formed with at least one engaging flange around the end. There is provided a terminal board having a locking notch formed therein. To install the terminal board, first insert the locking flange of the body into the locking notch of the terminal board and pivot the terminal board so that the flange catches the locking notch so that the terminal board and the body are quickly joined together or removed for replacement. It becomes possible. The body has two symmetrical sides forming a German ground groove, each side having a ground blade. One side of the ground blade is connected to the ground rack. After the body is inserted into the insertion groove of the German socket, the ground blade is connected to the ground lead. The adapter can also be inserted into a socket of French specification. The terminal board has a fixed position formed at a selected diagonal angle after pivoting with respect to the insertion port of the face panel. The conductive rack has an extension. After the terminal board has been pivoted at a selected diagonal angle on the fixed position, the tip of the terminal and the extension of the conductive rack remain in contact. Moreover, the terminal board has a ground port corresponding to the ground post of the French socket located on one side of the ground port formed in the adapter face panel at an oblique angle. Thus, when the adapter is inserted into the French socket, the ground struts pass through the ground port of the terminal board and make contact with an arcuate contact located on one side of the corresponding ground blade of the body to achieve a grounding effect. The adapter of the above configuration can be manufactured and assembled quickly and at a lower cost with a simpler structure. It can also be used as a normal adapter and can be applied to sockets according to French and German specifications. The universal adapter thus formed has a simpler structure and enhanced functionality.

The above-mentioned reference patent is to enable the user to supply power to the electrical appliance by changing the connector to meet the socket specifications of each region during the overseas travel. However, even if the adapter provides a suitable function and is configured to be immediately changeable for the socket, there is a disadvantage that the size of the adapter must be increased to perform a complex function. This can be a big burden on the user when traveling. It is a technique recognized by applicants to confer complex functionality to smaller adapters. In addition, the German and French sockets have a safety design formed in the recess, so that the current universal connector adapters correspond to the recess, which cannot be shared with other insertion terminals (because the length of the terminal is too short). You must provide a connector that can be matched. All of these are issues that still need to be addressed in the industry.

The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide an adapter for a connector having two or more sets of insertion terminals that can be selectively inserted into sockets of different specifications. The two sets of insertion terminals are pivotally coupled to the adapter in opposite open ways, reducing the space taken up by the plurality of sets of insertion terminals and allowing the set of insertion terminals to be erected upright so that they can be inserted into the corresponding sockets. do. The insertion terminal can also be folded into the adapter's housing groove when not in use, reducing the space taken up by the entire adapter, making it easy to carry around when traveling.

Another object of the present invention is to provide an adapter for a connector which can prevent the insertion terminal from hurting a person or an article. Since the two insertion terminals are located in the housing groove formed in the adapter and do not extend outward, there is no damage.

It is a further object of the present invention to provide an adapter for a connector which can be increased in availability. The insertion terminal is coupled to the adjustable length member. Thus, the adapter can be connected to the German and French sockets having grooves without lack of length, thereby being able to be powered.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 to 6 show embodiments of the present invention. The adapter 1 for a connector according to the present invention is for coupling electrical connectors and connectors of different specifications so that an electrical connection can be made therebetween. The adapter 1 is formed of an insertion portion 50 having a plurality of connection ports 51 (see Fig. 8) into which the conductive terminals of the connector are inserted, and a position corresponding to the corresponding socket (not shown). And a connecting portion 10 having a first terminal set 20 and a second terminal set 30. The connecting portion 10 further includes a housing groove portion 11 for accommodating two terminal sets 20, 30, the two terminal sets 20, 30 pivoting at two opposite ends of the housing groove portion 11. It is possibly coupled to be extended outwardly or inwardly of the housing groove 11 in a manner opposite to each other. In the use of the adapter 1, a set of terminals corresponding to the socket specifications are selectively pivoted to stand up on the connection 10 (FIGS. 1 and 5 show that different types of terminal sets are selected), so that the socket Facilitates insertion into the interior. When the adapter 1 is detached from the socket, the two terminal sets 20 and 30 can be accommodated inside the housing groove 11 without extending out of the connecting portion 10 (see Fig. 12). As such, the adapter 1 may be used in various ways to hold a plurality of sets of terminals having different specifications that correspond to the corresponding sockets.

The above-mentioned first and second terminal sets 20 and 30 each include, for example, an American flat terminal 21 and a European circular terminal 31. In this embodiment, the two types of terminals 21 and 31 are spaced at different intervals, that is, the second spacing B between the American flat terminals 21 is the first spacing between the European terminals 31. It is set smaller than A). Therefore, the American flat terminal 21 can be installed without mutual interference in the first gap A between the European circular terminals 31. In the state separated from the socket, the two terminal sets 20 and 30 are pivoted to be received inside the housing groove 11 so as not to extend out of the connecting portion 10. Therefore, the space occupied by the adapter 1 becomes smaller, and there is no fear of damaging or damaging a person or an article (see Fig. 12). 1 and 2, during use, the first terminal set 20 or the second terminal set 30 can be selectively inserted into a corresponding socket, thereby receiving power from sockets of various specifications. It becomes possible. The present invention is not limited to adopting the European terminal 31. As shown in FIG. 6, the second terminal set 30 ′ may also include English rectangular terminals 31 ′ spaced at a third spacing C greater than the second spacing B of the American terminal. . Alternatively, the European terminal 31 may be replaced with an English rectangular terminal 31 '.

Moreover, according to the safety factor and different connector regulations in different countries, sockets used in many countries, such as the United Kingdom, have a grounding port to have a grounding terminal. Thus, the adapter 1 may include a ground terminal 32 as shown in FIG. The ground terminal 32 is hinged to an appropriate position in the housing groove 11 so that it does not extend out of the connection portion 10 when not in use, and is swiveled upright on the connection portion 10 when in use, and inserted into a corresponding ground port of the socket. It becomes possible.

Referring to Figure 2, the English socket has a ground port as a means of safety. Until the ground terminal 32 is inserted, the terminal 31 can not receive power from the socket. Through the ground terminal 32 according to the invention, even if the European round terminal 31 is formed in the adapter 1, once the ground terminal 32 is erected upright, the European round terminal 31 is English Power may be applied from the socket. The ground terminal 32 may be formed of an insulating material or a conductive material, but is not necessarily conductive and grounded. As long as the safety means of the British socket are opened, the terminal 31 can be inserted into the socket to receive power.

7 and 8, the adapter 1 has two sets of terminals 21 and 31 and a conductive member 40 which makes electrical connection with the conductive terminals of the connector. The conductive member 40 has two contact ends 41 extending to two terminal sets 20 and 30 side. In use where the terminals 21 and 31 are in an upright position, one terminal set is in contact with the contact end 41 to make an electrical connection with the connector.

Referring to FIG. 8, the first terminal set 20 is fixed on the insulating terminal sheet 22 by the fixing member 23. The terminal sheet 22 has a pair of first protruding shafts 221 on both sides thereof. The connecting portion 10 has a guide track 14 formed at an inner end corresponding to the first protruding shaft 221 so that the first protruding shaft 221 can pivot about the guide track 14. Therefore, when the first terminal set 20 is upright and in use, the first protruding shaft 221 is fixed after turning in the guide track 14. The flat terminal 21 makes an electrical connection with the conductive terminal of the connector via the conductive member 40.

The second terminal set 30 is provided in the insulated connecting bar 301 located at one end of the adapter 1, and a connecting end 303 is formed in contact with the contact end 41. The connecting bar 301 has two second protruding shafts 302 on both sides thereof. The connecting portion 10 has a rotary groove 13 formed at an inner end corresponding to the second protruding shaft 302. Accordingly, the second terminal set 30 may be pivoted upright by the second protruding shaft 302 and the rotary groove 13 to be in use, or may be pivoted to be accommodated in the connecting portion 10.

9 and 10, when the second terminal set 30 has a European circular terminal 31, each circular terminal 31 has an extension member 314 having a hollow end with a boss 315 formed therein. ) Is combined. The circular terminal 31 is covered with an insulating layer 316, and a sliding slot 311 is formed in the insulating layer 316 to allow the boss 315 to slide. In the sliding slot 311, a first locking groove 312 is formed at the front end portion, and a second locking groove 313 is formed at the lower end thereof so that the boss 315 is caught by the first and second locking grooves 312 and 313. The extension member 314 is fixed to the front end and the bottom end to form the first fixed position and the second fixed position, and also makes electrical connection with the circular terminal 31. This structure is for adjusting the length of the circular terminal 31. For example, when the present invention is adopted for use in a German or French socket (not shown), the adapter (1) is coupled to the socket as the socket has a safety groove and an insertion port is formed on the bottom side of the safety groove. The circular terminal 31 of) may be adjusted to a longer length to offset the gap formed between the coupling side and the insertion port. In summary, the structure of the circular terminal 31 as described above has the following main features. The second fixing position of the boss 315 corresponds to the insertion port located in the normal plane of the socket. The boss 315 is caught in the second locking groove 313 so that the extension member 314 is in the second fixing position. To be fixed. Therefore, the circular terminal 31 can be reliably inserted without any looseness in the insertion port provided in the normal plane of the socket. In response to the insertion requirement of the German or French socket, the boss 315 is displaced from the second locking groove 313 to avoid the circular terminal 31 becoming too short, and the circular terminal along the sliding slot 311. The extension member 314 can be fixed to the first fixing position by slidingly moving to the front end of the 31 and engaging the first locking groove 312. In addition, the circular terminal 31 is inserted into the German or French socket through the extension member 314 to receive power. 13 and 14 show another embodiment of the circular terminal 31 and the extension member 34. Threads 341 and 342 are formed at both ends of the extension member 34, respectively. The circular terminal 31 has a hollow shape, and the conductive member 33 of the extension member 34 is coupled therein. The extension member 34 has a terminal head portion 36 at one end and a sealing member 35 for sealing the hollow circular terminal 31 at the other end. The conductive member 33 has another threaded portion 331 on the inner wall so as to correspond to the extended member 34, thereby transferring the threaded portions 341 or 342 of the extended member 34 to the threaded portions 331 of the conductive member 33. The extension member 34 is slidably moved to the first fixed position and the second fixed position to engage. 5, 11A and 11B, the adapter corresponding to the Australian socket is formed so that the insertion port has a predetermined diagonal angle D and has a size corresponding to the American flat terminal 21. Let's do it. In order to increase the availability of the adapter 1, when the first terminal set 20 is in use, the fixing member 23 of the first terminal set 20 is fixed to the terminal sheet 22 and the first Being pivotable about the protruding shaft 221 allows the first terminal set 20 to move so that the flat terminal 21 is inclined to conform to the Australian socket. The connecting portion 10 and the terminal sheet 22 include notches 12 and 222, respectively, inclined at a diagonal angle D in order to support the inclined flat terminal 21.

12 and 15 show another embodiment of the adapter 1 according to the invention with the terminals folded. Since the first and second terminal sets 20 and 30 are folded into the housing groove 11 and do not extend out of the connecting portion 10, the overall size of the adapter 1 can be reduced, and a person or an article is damaged. I will not damage.
