Reversible power supply

The present invention relates to a power supply, and more particularly to a reversible power supply.

Referring to FIG. 1 and FIG. 2, a plug-detachable multi-directional power supply 1 disclosed in Taiwan Patent No. 1444818 is mainly used to include a main body 11 and a plug 12. The body 11 includes two guiding terminals 111 formed on one side, a convex ring 112 surrounding the guiding terminal 111, and two latching blocks 113 formed on the protruding ring 112. The plug 12 includes a base 121 formed with an accommodating space 120, two insertion pieces 122 extending through the base 121, and is disposed in the accommodating space 120 and can be guided with the guiding terminal 111. Two guiding pieces 123, a brake ring piece 124 and a positioning cover 125 are connected.

Thereby, the body 11 can be rotated in the positive and negative directions, and the blocking relationship between the clamping block 113 and the positioning cover 125, the limiting relationship between the guiding terminal 111 and the braking ring piece 124, and The guiding relationship of the guiding strips 123 reaches the limit of the plug 12 and the purpose of changing the angle of the plugs 122 relative to the body 11.

However, since the seat body 121 of the plug 12 must accommodate the components such as the plug piece 122, the guide piece 123, the brake ring piece 124, the positioning cover 125, etc., the volume is limited not only by the aforementioned components but also by the components. Can not be reduced, and the structure is complicated, the installation is not easy.

Moreover, the positioning body 111 is only blocked by the guiding terminal 111 to block the positioning groove of the arcuate portion of the brake ring piece 123. Therefore, the seat body 121 is easily rotated by the external force inadvertently touching. There are disadvantages of poor positioning.

Accordingly, it is an object of the present invention to provide a reversible power supply that is compact in construction, easy to install, and stable in positioning.

Thus, the novel reversible power supply comprises a housing, a carrier, two guiding terminals, a connector, and a fastener.

The carrier is disposed on the housing and includes a receptacle.

The conductive terminals are disposed on the carrier, and each of the conductive terminals includes two guiding portions disposed between the insertion holes and spaced 90 degrees apart from the axis.

The connector includes a socket rotatably threaded through an insertion hole of the carrier, and two plug terminals extending through the socket in a direction parallel to the axis, the socket having an inner side formed At least two engaging portions spaced 90 degrees apart from the axis.

The fastener is supported by the carrier and includes a buckle that moves relative to the carrier between a latching position and an unlocked position, the latch being engaged with one of the latches of the connector when the latching position is Leading each of the plug terminals to any one of the guiding portions of the respective guiding terminals. When the unlocking position is performed, the buckle is disengaged from the locking portion of the relative position, so that the joint can be forward and reverse. The direction is swivel.

The utility model has the advantages of: utilizing the guiding portions which are placed on the carrier and spaced 90 degrees apart, and the fastener supported by the carrier, so that the connector can be connected with the plug terminal every 90 degrees of rotation The guiding portion is guided and engaged with the fastener to obtain positioning, thereby not only simplifying the assembly of the joint, but also improving the stability during positioning.

The driving portion 62 is forced by an external force to drive the buckle 61 to be displaced to the unlocked position.

When the joint 5 is assembled, the flap 513 of the joint 5 can be passed through the notch 313 of the panel 31, and the ring wall 511 of the joint 5 can be inserted into the panel 31 along the axis X direction. In the hole 310, at this time, as shown in FIG. 5, the joint 5 is rotated about 45 degrees in the forward direction, or the joint 5 is reversely rotated about 45 degrees as shown in FIG. 8, so that during the rotation, The fins 513 and the ring ribs 312 of the panel 31 are mutually blocked, so that the joint 5 cannot be displaced along the axis X direction, and when one of the fins 513 is blocked by one of the limiting portions 314, each of them can be The contact portion 522 of the plug terminal 52 is in contact with one of the guiding portions 41 of the respective guiding terminals 4 and located at an opposite position, and the buckle 61 of the fastening member 6 is just capable of being in one of the opposite positions. The 512 is engaged and located at the latch position so that the joint 5 cannot be rotated about the axis X.

Referring to FIG. 6, FIG. 7, and FIG. 8, when the insertion angle of the joint 5 with respect to the outer casing 2 is to be changed, only the driving portion 62 of the fastener 6 is forced to be pressed, so that the driving portion 62 is forced by the foregoing. The external force drives the buckle 61 to be displaced to the unlocked position, and the joint 5 can be rotated without departing from the panel 31, until the flap 513 is blocked by the other limiting portion 314, The contact portion 522 of the plug terminal 52 is in contact with the other guiding portion 41 of the respective guiding terminal 4 and located at the opposite position, and the buckle 61 of the fastener 6 is just capable of the other locking portion at the opposite position. The 512 is engaged, and the position of the lock is such that the joint 5 cannot be rotated about the axis X, and the purpose of changing the insertion angle of the plug terminals 52 with respect to the outer casing 2 is achieved.

It should be noted that the connector 5 shown in FIG. 3 can be replaced with the plug terminal 52 of other specifications by using the plug terminal 52 conforming to the US standard. Since the general knowledge in the art can infer the details of the expansion based on the above description, it will not be explained.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows: the present invention can form four guiding portions 41 separated by 90 degrees by using only two guiding terminals 4 piercing the carrier 3, and The fastener 6 supported by the carrier 3 can be used to guide the connector 5 to the guide portions 41 every 90 degrees of rotation, and can be engaged with the fastener 6 to obtain positioning. Therefore, the connector 5 is simply provided with a socket 51 and two plug terminals 52, which not only simplifies the assembly, reduces the size, and improves the installation convenience, and the fastener 6 can lift the connector 5 in the positioning. The stability of time.
