A compact and electrically grounded enclosure facilitates locating a board stack assembly camera inside and can be rated IP67 or higher. The enclosure has connectors integrated ended in the back bezel of the enclosure and a front lens mount that allows for the direct assembly of interchangeable lens covers. The purpose of the enclosure is to take an existing board stack and locate it within the enclosure thereby forming a camera assembly. The enclosure and its packaging have improved interchangeability of the lens covers and back pieces, as well as heat transfer. Methods for assembling and mounting the board stack within the enclosure and securing the enclosure are also disclosed.

A dual sealing ring connector comprising: a first resilient sealing ring; a second resilient sealing ring partially embedded in the first resilient sealing ring; characterized in that the dual sealing ring connector comprises a holding portion and an inserting portion; the inserting portion is shaped to correspond to the holding portion and embedded into the holding portion; the inserting portion comprises a joint head, a joint rod, and locking tabs; the joint rod extends in a radial direction, an axial direction or a circumferential direction; the joint head is arranged at the end of the joint rod and is mirror image symmetrical with regard to its axis of symmetry; the locking tabs are arranged on both sides of the joint rod and are spaced apart from the joint rod by a distance; the locking tabs extend in the same direction as the extension direction of the joint rod, and its length in the extension direction is less than of the sum of the lengths of the joint head and the joint rod in the extension direction of the joint rod.

A split oil seal composed of double springs and double rings comprises an elastic outer ring intended to be statically mounted in a cavity outside a bearing box or gear box, and an elastic inner ring intended to be sleeved on a shaft of the device and held by the outer ring. The outer ring has an outer ring cut and the inner ring has an inner ring cut. The split oil seal further comprises a radial forcing element and a circumferential forcing element, wherein the radial forcing element exerts tension in both directions directed to outer circumferences and inner centers of both the outer ring and the inner ring in radial directions thereof, and the circumferential forcing element exerts a circumferential closing force to the inner ring. By using the split oil seal composed of double springs and double rings of the present invention, the advantages of convenient mounting and removal as well as strong anti-disengaging ability are achieved.
