The first arc wall 31 further has an inner side 312 with a concave arc surface and an outer side 313 opposite to the inner side 312. The first side walls 32 are connected to two sides of the first arc wall 31 opposite to each other. The wing portions 33 extend from the first side edges 311 in opposite directions, respectively, for being fixed to an apparatus housing 7 of the photographing apparatus 100.
The conductive elastic pieces 4 are arranged in parallel with each other at intervals on the first arc wall 31. Each conductive spring 4 has a spring arm 41 located on the inner side 312 and extending in the circular arc shape along the circumferential direction C in cooperation with the first arc wall 31. In this embodiment, each conductive spring 4 further has a fixing portion 42 located on the outer side 313 and fixed to the first insulating housing 3, and a connecting portion 43 connecting the fixing portion 42 and the spring arm 41. The fixing portion 42 is used for connecting a wire (not shown) to be electrically connected with a control circuit (not shown). The first arc wall 31 further has a plurality of mounting through slots 314 corresponding to the conductive elastic pieces 4, so that when the conductive elastic pieces 4 are assembled to the first arc wall 31, the elastic arm 41 and the connecting portion 43 of each conductive elastic piece 4 can pass through the corresponding mounting through slots 314 from the outer side 313, and the elastic arm 41 is located on the inner side 312.
Referring to fig. 1, 2 and 5, the rotary base 2 includes a second insulating housing 5 and a conductive terminal set 6. The second insulating housing 5 has a second arc wall 51 matching with the first arc wall 31, and two second side walls 52 opposite to each other and respectively connected to two sides of the second arc wall 51, and the second side walls 52 respectively correspond to the first side walls 32 and are located on opposite inner sides of the first side walls 32 (see fig. 3), so that a portion of the second insulating housing 5 is accommodated in the first insulating housing 3 in a shape and size matching with the first insulating housing 3 and can slide along the circumferential direction C relative to the first insulating housing 3. In the present embodiment, the arc length of the second arc wall 51 is greater than the arc length of the first arc wall 31, and the arc length of the second arc wall 51 is greater than the semicircle circumference, so that the second arc wall 51 and the whole area of the first arc wall 31 can overlap in the rotation range of the second insulating housing 5. The second arc wall 51 has an outer arc surface 511 that can slide along the circumferential direction C relative to the inner side surface 312, and a plurality of through holes 512 respectively corresponding to the conductive elastic pieces 4. In the present embodiment, the through holes 512 are located at the middle position of the second arc wall 51. In addition, in the present embodiment, the second insulating housing 5 further has two shaft portions 53 extending from the second side walls 52 respectively in opposite directions, and the shaft portions 53 are located at the center of the second arc wall 51 to form the rotation axis of the second insulating housing 5 together, so as to pivotally connect with the equipment housing 7, so that the second insulating housing 5 is pivotally connected with the equipment housing 7 and can rotate about the rotation axis formed by the shaft portions 53.
The conductive terminal set 6 is located in the second insulating housing 5, and has a circuit board 61 and a plurality of conductive terminals 62 disposed on the circuit board 61 and electrically connected to the circuit board 61, wherein the conductive terminals 62 respectively correspond to the through holes 512. Each conductive terminal 62 has a resilient contact portion 621 penetrating the corresponding through hole 512 and elastically extending out of the outer arc surface 511, and the resilient contact portion 621 is configured to contact the corresponding spring arm 41 and slide relative to the spring arm 41. In this embodiment, each conductive terminal 62 is a spring probe (pogo pin). In the present embodiment, the conductive terminal set 6 further has an insulating base 63 for holding the conductive terminals 62. The second insulating case 5 further has a pair of abutting portions 54 formed inside the second arc wall 51 for the circuit board 61 to abut.

In the present embodiment, the photographing apparatus 100 further includes a lens housing 8 for surrounding and fixing the lens module 20, and the lens housing 8 is assembled with the second insulating housing 5.
Referring to fig. 6 to 8, when the photographing angle of the lens module 20 is to be adjusted, the lens module 20 can be rotated together with the rotating base 2. When the rotating base 2 rotates, the elastic contact portions 621 of the conductive terminals 62 can stretch and contract along the spring arm portions 41 of the corresponding conductive spring plates 4, as shown in fig. 8, when the elastic contact portions 621 are pressed, they can contract inwards, and when the lens module 20 rotates to a desired position for positioning, as shown in fig. 6 and 7, the elastic contact portions 621 are pressed against the spring arm portions 41 by elastic force to maintain stable contact, i.e. maintain the stability of electrical connection. Moreover, when the rotating base 2 is located at a different angle, the contact stress of the elastic contact portion 621 and the corresponding spring arm 41 is the same, that is, the contact stress of the elastic contact portion 621 at different contact points on the spring arm 41 is the same, so that it is ensured that the elastic contact portion 621 maintains good contact with the corresponding spring arm 41 under frequent rotation of the lens module 20.
By means of the conductive terminal 62 of the rotating base 2 can slide relative to the conductive spring plate 4 of the fixed base 1 and can maintain stable contact, stable electrical connection can be maintained. Compared with the existing electrical connection mode using a soft flat cable, the method can not only increase the reliability of the product to reduce the maintenance cost, but also avoid the trouble of wire arrangement.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
