Abstract: A housing assembly includes a main body, a button, a base, and a fixing member. The main body has an inner space and a through hole communicated with each other. The button includes a pressing portion. The pressing portion protrudes out of the main body from the through hole and is configured to be pressed to sink into the through hole. The base has a recess and an engaging hole communicated with each other. The recess is configured to accommodate the main body. The engaging hole is configured to be engaged with the pressing portion. The fixing member is coupled to the main body in the inner space and configured to block the pressing portion from sinking into the through hole and disengaging from the engaging hole.

Abstract: The present application discloses monitoring system, which includes a mounting base and a monitoring device. The mounting base includes a base, a first cover, a second cover and a fastening member. The base includes a ball shaft and a first wire accommodating portion located in the ball shaft. The first cover and the second cover are sleeved on the outside of the ball shaft. The second cover includes a second wire accommodating portion, an outer screw thread and a connecting portion, and the outer screw thread is adjacent to the connecting portion. One end of the fastening member is connected to the first cover, and the fastening member is screwed to the second cover. The monitoring device includes a housing connected to the connecting portion of the second cover, and a wire accommodated in the first wire accommodating portion and the second wire accommodating portion.

Abstract: A camera module includes a first holder, a second holder, a waterproof O-ring, and a camera. The second holder is disposed on the first holder, in which the first and second holders collectively form an accommodating space. The waterproof O-ring is disposed between the first and second holders and is at least in contact with the second holder. The camera is disposed within the accommodating space, in which a vertical projection of the waterproof O-ring onto the first holder is separated from the camera.

Abstract: An electrical connector includes an insulating housing and a plurality of terminals coupled to the insulating housing. The insulating housing includes a positioning body, a head portion extending from a first face of the positioning body, and a tail portion extending from a second face of the positioning body. Each terminal includes a first contact portion, a second contact portion, and a retaining portion between the first contact portion and the second contact portion. The retaining portion includes a first coupling portion coupled to the first contact portion and a second coupling portion between the first coupling portion and the second contact portion. The first coupling portion and the second coupling portion are noncoplanar. The first contact portion is coupled to the head portion, the second contact portion is coupled to the tail portion. The retaining portion extends from the head portion to the tail portion.
