As shown in fig. 2 to 3, two conductive sheets 4 are disposed on the back plate 12 and are confined in the housing 2. As shown in fig. 4 to 5, after the two pins 51 are inserted into the sliding slot 6 from the opening 22 and the turntable 3 is driven to rotate 90 degrees to a conducting position, the two pins 51 are flush with the outer side 141 of the wall portion 14 and are straight, and are pressed by the two conductive sheets 4, so that the two pins 51 and the two conductive sheets 4 are electrically connected by surface contact.
In addition, the inner peripheries 142 of the wall portions 14 are recessed near the back plate 12 to form a pair of hook portions 143, the rotary plate 3 has a shaft portion 33 extending from the panel portion 31 beside the second groove portion 32, and a protruding stop portion 331 is provided at an end of the shaft portion 33, the stop portion 331 is stopped in the pair of hook portions 143 when the rotary plate 3 is assembled in the housing 2 to restrain the rotary plate 3 in the housing 2. In addition, when the panel portions 31 of the turntable 3 beside the second groove portion 32 are laterally moved, the blocking portions 331 are blocked by the pair of hooks 143, so that the panel portions 31 are not moved outward, thereby enhancing the structure of the turntable 3.
as shown in fig. 6, the periphery 141 of the pair of wall portions 14 has a plurality of positioning portions 144 at the top, and when the rotary plate 3 is assembled in the housing 2 and is limited in the housing 2, a corresponding buckling portion 34 is respectively disposed at the position of each of the plurality of positioning portions 144, so that when the rotary plate 3 is at the inserting position or rotated 90 degrees to the conducting position, the plurality of positioning portions 144 and the corresponding buckling portions 34 can be buckled with each other to perform temporary positioning. As shown in fig. 7, the plural positioning portions 144 and the corresponding engaging portions 34 are separated from each other.
It is obvious from the above description that the present invention has the advantages that the outer periphery 141 of the pair of wall portions 14 is a straight cylindrical surface without protrusion, and the width of the outer periphery 141 of the pair of wall portions 14 is equal to the distance between the two pins 51, when the two pins 51 of the lamp 5 are placed in the sliding slot 6 and the pins 51 of the lamp 5 are inclined (as shown in fig. 4, one pin 51 is inclined inward), the inclined pin 51 is supported by the outer periphery 141 of the wall portion 14 when the lamp 5 rotates, so that the two pins 51 can be centered, the two pins 51 are flatly attached to the outer periphery 141 of the wall portion 14, the two pins 51 are straight (as shown in fig. 5), and the two pins 51 are also pressed by the two conductive sheets 4, so that the two pins 51 and the two conductive sheets 4 can be electrically connected by surface contact, thereby solving the problem that the lamp socket has poor contact due to the inclined pins and the easy contact.
There are, of course, many examples of this invention and only variations in detail therebetween. Referring to fig. 8 to 10, which are a second embodiment of the present invention, it can be seen that there is a gap 7 between each conductive sheet 4 and the back plate 12 in the set position, in cooperation with the first embodiment (see fig. 2). The main difference between this embodiment and the first embodiment is that the back plate 12 has a blocking portion 16 in the gap 7 at the position where each conductive sheet 4 is disposed, two blocking portions 16 are disposed outside the pair of wall portions 14 corresponding to the tracks where the two pins 51 drive the turntable 3 to rotate 90 degrees, and the width between the inner sides of the two blocking portions 16 is equal to the distance between the outer sides of the two pins 51.
As shown in fig. 9, when one of the pins 51 is tilted outward, after the two pins 51 drive the turntable 3 to rotate 90 degrees, as shown in fig. 10, the pins 51 are not only pressed by the conductive sheet 4, but also the tilted pins 51 are blocked by the blocking portion 16 and are aligned toward the wall portion 14, so that the two pins 51 and the two conductive sheets 4 can be electrically connected by surface contact, which can achieve the same effect as the first embodiment, and can also enhance the alignment toward the wall portion 14 when the pins 51 are tilted outward.
The foregoing description of the embodiments is provided to illustrate and not to limit the invention, and changes in values or substitutions of equivalent elements are intended to fall within the scope of the invention.
