Description

TECHNICAL FIELD OF THE INVENTION The present invention generally relates to a German / French type electrical power outlet having multiple possible pin arrangements adapted to the different types of female sockets of various countries and / or areas. geographical. (b) Description of the Prior Art Electrical appliances used in different countries of the world are often supplied with direct current (DC) which is converted from AC (alternating current). This technique has been widely used. Since an AC voltage of 110V or 220V, after having been converted to direct current, generally meets the safety standards for its use, such a characteristic of the electric current can protect electrical devices and is widely adopted in the world whole. However, the electrical outlet configurations used around the world are different from one country or geographical area to another, which causes difficulties for manufacturers and consumers. Various adapters available on the market can be structured to perform a single adaptation or can be convertible into multiple pin configurations, allowing for a selective connection to an appropriate conventional outlet, or to change their configuration for arrangement. chosen from different conductive pins compatible with outlets of unusual types. These known devices, however, do not provide a structure that actually meets the standards adopted in various countries and / or geographical areas and can sometimes be cumbersome due to the number of adaptable connection accessories that accompany them.

In addition, the multi-pin adapters that are currently available on the market do not incorporate a grounding function. They do not meet the grounding requirements specified by some manufacturers.

SUMMARY OF THE INVENTION The main objective of the present invention is to provide an all-in-one portable power supply that allows for different pin arrangements adapted to different types of female power outlets adopted in different countries and regions. 1 To achieve the above objective, the following technical solution is adopted. The present invention relates to a German / French type electrical power outlet having multiple possible pin arrangements, which includes an outer shell, an inner housing, a thrust plate, a strain plate, and a plurality of branch units. The plurality of branch units includes a first branch unit, a second branch unit, and a third branch unit. The branching units are arranged in the outer casing and / or the inner casing and are each provided with an actuating latch. The actuation catches are movable along a plurality of rails formed in a side wall of the outer casing. To move the actuating tabs, the stress plate is first moved in the direction of its removal from a rest position, being free sliding. Maneuvering the actuating cleats causes protruding pins that include the branching units through holes in the outer casing or through openings in the inner casing for insertion into corresponding female electrical outlets . The second branch unit includes a bias section, which is received with the possibility of movement in a constraint slot in the inner case. This structural arrangement allows the inner housing to protrude outwardly to form a stepped configuration, which causes the second branch unit to protrude further to form a different pattern for the connection to the electrical network. A second object of the present invention is to make it possible to mount a conductive grounding member according to the environment of use to meet the needs of users. Another object of the present invention is to provide a plug which is compact in size and easy to carry.

DETAILED DESCRIPTION OF THE INVENTION In FIGS. 1 and 2, which are respectively a perspective view and an exploded view of a preferred embodiment of the invention, there is shown a German / French type power plug having multiple possible pin arrangements according to the present invention. The German / French type electrical power socket 1 mainly comprises an outer casing 10, an inner casing 11, a stop plate 12, a stress plate 13, and a first branch unit 14, a second branch unit 15. and a third branch unit 16. The outer shell 10 comprises a side wall in which a plurality of slides 102 is provided and an upper wall adjacent to the side wall, including a plurality of through holes 104. The outer shell 10 forms internally a constraint rail 106, and this outer casing 10 receives the inner casing 11 within it. The inner housing 11 comprises a constraining member wall 110, which is engageable by coupling with the constraint rail 106, and also forms a stress slot 112 at a location close to the biasing member 110. inner housing 11 includes an upper portion forming a plurality of through openings 114. In addition, the inner housing 11 forms a retention projection 116 extending from one of its outer surfaces, and the retention projection 116 is adapted to come into engagement with a retention chute 120 which is arranged in a portion protruding from a predetermined location of the abutment plate 12. The abutment plate 12, which is received in the outer casing 10, blocks part of the passage constraint 130 along which the second branch unit 15 is movable. The second branch unit 15 is limited in its movement because it is constrained by the inner case 11 in a vertical direction. In addition, the stress plate 13 which is received in the outer casing 10 forms a plurality of stress passages 130 respectively corresponding to the slides 102, and each stress passage 130 comprises a plurality of locking portions 132. The constraint plate 13 comprises a switching protruding member 134 extending through one of the slideways 102 to allow to act on the switching position of the switching member. The stop plate 12 and the stress plate 13 are each equipped with elastic members 122, 136 which are supported on inner walls of the outer casing 10. The first branch unit 14, the second branching unit 15, and the third branching unit 16 are each provided with at least one conductive pin 140, 150, 160 (a plurality of pins is shown in the figures) and an actuating latch 142, 152, 162 movably mounted in one of the respective slides 102 and constrained by a respective constraint passage 130. The conductive pins 140 of the first branch unit 14 are able to be received through the through holes 104 of the outer casing 10 and the conductive pins 140 can be made of various materials according to the desired applications (for example of plastic materials or metal). The conductive pins 150 of the second branching unit 15 are able to be received through the through openings 114, and a constraining portion 154 is arranged at a predetermined location of the second branching unit 15, the constraining portion 154 constraining the second branching unit 15 in the constraint slot 112. In addition, the conductive pins 160 of the third branching unit 16 are able to be received through the through openings 114, and the third branching unit 16 is equipped with rotating pin 164 for rotating the conductive pins 160 to change the directions of the conductive pins 160.

The outer casing 10 is mounted on a base 17. The base 17 comprises a plurality of connection holes 170 whose function is to receive an external electrical outlet (not shown), these holes being electrically connected to the connection units 14, 15, 16 (see also FIG. 19). A conductive spring plate 118 is disposed within the outer casing 10, and the conductive spring plate 118 provides an electrical connection with a conductive grounding member 2. Reference is now made to FIGS. 3, 4, 5, 6, and 7, which are respectively a perspective view showing a first phase of use of the first branch unit (layout of the British type pins), a perspective view. illustrating the movement of the internal components associated with the use according to FIG. 3, a perspective view showing a second phase of use of the first branching unit (layout of the British type pins), a perspective view illustrating the movement of the internal components associated with the use according to Fig. 5, and a perspective view showing the arrangement of the conductive grounding member. In these figures, it is clearly shown the use of the British-type pin arrangement whose operation and structure are described below. Firstly, the switching member 134 of the stress plate 13 is pushed so that the switching member 134 is moved along the slide 102. Under this condition, the elastic member 136 of the plate stress 13 is compressed. Since the stress plate 13 is displaced, for example to the right, the actuating latch 142 of the first branching unit 14 is moved from one of the locking portions 132, in which the actuating catch is initially located, to the associated constraint passage 130. This allows a user to push the actuator latch 142 upward, so that the conductive pins 140 of the first branch unit 14 protrude outwardly. Once the actuating latch 142 is moved to the uppermost position, the stress plate 13 is driven by the elastic force resulting from the release of the elastic member 136 to return to its initial position, so that the cleat actuator 142 engages with another locking portion 132, which effectively locks the first branch unit 14 in the locking portion. On the other hand, to retract the conductive pins 140 of the first branch unit 14, a reverse operation is performed. The method described above makes it possible to configure the first branch unit 14 as a British type electrical outlet. FIG. 7 shows that the conductive grounding member is directly engaged on one of the conductive pins 140 of the first branching unit 14. This conducting pin 140 is provided with a retention member 1402, and the retention member 1402 is arranged to allow a selective engagement with a barbule 20 arranged on the conductive member 2 of grounding, and thus to retain this barbule. Since this conductive pin 140 is connected to the conductive spring plate 118, the grounding can be performed. Reference is now made to Figures 8, 9 and 10, which are respectively a perspective view showing a use of the second branch unit (German / French type pin arrangement), a perspective view illustrating the movement of the associated internal components in use according to Figure 8, and a perspective view showing the installation of the conductive grounding member for the arrangement of German / French type pins. The operation and structure of the German / French pin arrangement are described below. Firstly, the switching member 134 of the stress plate 13 is pushed so that the switching member 134 is moved along the slide 102. Under this condition, the elastic member 136 of the plate stress 13 is compressed. Since the constraint plate 13 is moved, for example to the right, the actuating latch 152 of the second branch unit 15 is moved from one of the latch portions 132, in which the actuating latch is located at the origin, towards the associated constraint passage 130. This allows a user to push the actuating latch 152 upwardly, causing the conductive pins 150 of the second branch unit 15 to protrude outwardly. Since the constraining portion 154 is arranged at a predetermined location of the second branch unit 15, the constraining portion 154 causes the second branch unit 15 to move along the constricting slot 112.

When the actuating catch 152 is pushed upwards to reach a middle portion, the stress plate 13 is driven by the force of the spring released by the elastic member 136 to return to the initial position, so as to bring the cleat actuator 152 to enter one of the locking portions 132 formed in the middle portion and coming into engagement therewith, thereby ensuring the locking the second branch unit 15 in the locking portion. This process configures the second branch unit 15 as a German / French type power socket. FIGS. 10 and 10a illustrate that the conductive member 2 for grounding a French-type power supply plug can be inserted directly into the through-hole 104 formed in the upper wall of the outer casing 10 Thus, a user can insert the conductive grounding member 2 into the through hole 104 according to the required local voltage and make the connection of the conductive grounding member 2 to the conductive plate-spring 118. In this way, a current leak from an electrical device can be grounded and the user can be protected against the risk of electric shock. FIG. 10b shows that, for adaptation to different required voltages, conductive sleeves 151 (used for currents such as 16A and 250V, and having a diameter of 4.8 mm) can be provided to be fixed, by a threaded mounting, at the second branch unit 15 (used for currents such as going from 10A to 250V, and having a diameter of 4.0mm). Thus, a user can choose to install or not the conductive sleeves 151 according to the required local voltage. Figure 10c is a perspective view illustrating the installation of different conductive sleeves for different countries or regions. To meet the different voltages required in different countries or regions, a suitable conducting sleeve 151a, which comprises a conductive grounding member 2, can be directly inserted on the second branching unit 15. This drawing also shows various conductive members 2 for grounding used in different countries or regions, such as a grounding conductor 2a for use in India, a conductive grounding member 2b for use in Italy (taking a type former), a conductive grounding member 2c for use in Switzerland (socket of an old type), a grounding conductive member 2d for use in Denmark, and a conductive member 2e of setting to the ground land for use in the Middle East. Thus, a user can choose to install these conductive sleeves 2 according to the required local voltage and to carry out the grounding.

Reference is now made to Figures 11, 12, 13, 14 and 15, which are respectively a perspective view showing a first phase of a combined use of the extension of the inner case according to the invention and the use of the second branching unit (arrangement of the European type pins), a perspective view illustrating the movement of the internal components in a second phase of the combined use, a perspective view illustrating the associated movement of the inner case and the stop plate, a perspective view illustrating the extension of the inner envelope, and a perspective view showing the installation of the conductive grounding member for a European-type pin arrangement. If it is to use this European-type pin arrangement, in order to cause the inner case 11 to protrude upwardly, the switch member 134 is pushed to allow the strain plate 13 to move again. Under this condition, the actuating catch 152 is moved upwardly further. During this upward upward movement, the portion of the stress passage 130 along which the second branching unit 15 is movable, which is originally blocked by the stop plate 12, is released due to a laterally forced displacement of the stop plate 12; at the same time, when the stop plate 12 is moved laterally, the retention chute 120 of the stop plate 12 is disengaged from the retention projection 116 which extends from a predetermined location of the outer surface of the inner housing 11 so as to place the inner housing 11 in a state of free mobility. Then, due to the displacement of the actuating tab 152 upwards, and since the constraining portion 154 of the second branching unit 15 engages with an upper end of the constraint slot 112 of the inner case 11 and it is therefore retained by this end, the upward movement of the opening cleat causes the inner housing 11 to move with it and thus to project outside the outer casing to adopt a stepped configuration. This process configures a European-style power outlet. FIG. 15 illustrates that the conductive grounding member can be fixed directly, by means of a screw connection, to a hole 119 formed in the upper part of the inner casing 11, forming part of a number of such holes. Thus, a user can choose to install the conductive member 2 of grounding by a screw engagement in the through hole 119 corresponding to the required local voltage and to make the connection of the conductive member 2 of grounding to the conductive spring plate 118. In this way, current leakage from an electrical device can be grounded and the user can be protected against the risk of electric shock.

Reference is now made to Figures 16, 17, 18, 19 and 20, which are respectively a perspective view showing a first phase of use of the third branch unit (pin arrangement adapted for Taiwan / America / Japan), a perspective view illustrating the movement of internal components associated with operation according to Fig. 16, a perspective view showing a second phase of using the third branch unit (pin arrangement adapted for Taiwan / America / Japan), a perspective view illustrating the movement of the internal components related to the use according to Fig. 18, and a perspective view showing the installation of the conductive grounding member for the pin arrangement Suitable for Taiwan / America / Japan. To use the American-style pin arrangement, the operation and structure are as follows. Firstly, the switching member 134 of the stress plate 13 is pushed to cause the switching member 134 to move along the slide 102. Under this condition, the elastic member 136 of the plate stress 13 is compressed. Since the stress plate 13 is displaced, for example, to the right, the actuating catch 162 of the third branching unit 16 is displaced from one of the locking portions 132, in which the actuating catch is originally located, in the associated constraint passage 130. This allows a user to push the actuating tab 162 upwardly, causing the conductive pins 160 of the third branch unit 16 to protrude outwardly. Once the actuating catch 162 is moved to the uppermost position, the stress plate 13 is driven by the elastic force released by the elastic member 136 so as to return to the initial position, so that the cleat Actuation 162 enters another locking portion 132 and engages therewith, thereby effecting effective locking of the third branch unit 16 in the locking portion. On the other hand, to retract the conductive pins 160 of the third branch unit 16, a reverse operation is performed. FIG. 20 illustrates that the conductive grounding member 2 can be directly inserted into the through hole 104 provided in the upper wall of the outer casing 10, so that a user can directly insert the conductive member 2 of grounding in the through holes 104 according to the required local voltages. To take a South African type conductive grounding member 2 as an example, the conductive grounding member 2 is connected to the conductive spring plate 118 and the through hole 104 is provided, being similar to the through hole 104 shown in Figure 10, for the installation of the conductive member 2 grounding. The hole 104 in FIG. 10 allows the grounding conductive member 2 to be inserted or embedded therein, but the through hole 104 of the drawing being described can only allow the embedding. Reference is now made to Figs. 21 and 22, which are a perspective view showing a use of the third branch unit (inclined Austro-Asian type plug) according to the present invention and a perspective view illustrating an internal use of the third branching unit (inclined Austro-Asian type plug). In order to utilize the inclined Australian-Asian power supply, the conductive pins 160 of the third branch unit 16 are pivoted to correspond to the location of the through openings 114 provided in the upper portion of the inner case. 11. To rotate the conductive pins 160 of the third branch unit 16, the third branch unit 16 is provided with rotation members 164. When the conductive pins 160 are manipulated, the rotation members 164 allow the conductive rods to rotate. 160 to change direction in order to allow adaptation to the specifications of the Austro-Asian type plugs. Reference is now made to Fig. 23, which is a perspective view showing the installation of the conductive grounding member for an inclined Austro-Asian type plug. To allow a German / French 1 power supply 1 to have protection functions against damaging factors, such as current leaks and surges, which could damage the electronic product, the through holes 104 are arranged in the upper wall of the outer casing 10, so that a user can insert the conductive member 2 of grounding in the through holes 104 according to the required local voltages and make the connection of the Conductor member 2 for grounding conductive leaf spring 118. Reference is now made to Figure 24, which is a perspective view illustrating a combination of the present invention with a power cord.

A power cord 3 can be connected to one end of the power plug 1 of the German / French type, this power cord 3 allowing the power plug 1 of the German / French type to lie down to be connected to other electrical devices.

The branching unit 14, 15, 16 mentioned above may be provided with a conductive spring plate 118 disposed at any desired location according to the local standards of the countries and / or geographical areas in order to be connected to the conductive member 2 of grounding.
