The present disclosure discloses an optical imaging lens assembly including a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens, each of which has refractive power. The first lens has a negative refractive power; the the third lens and the sixth lens each has a positive refractive power; an object-side surface of the fourth lens is convex, and an image-side surface thereof is concave; an object-side surface of the fifth lens is convex,and an image-side surface thereof is concave. A distance TTL along the optical axis from an object-side surface of the first lens to an imaging plane of the optical imaging lens assembly and half of a diagonal length ImgH of an effective pixel area on the imaging plane of the optical imaging lens assembly satisfy TTL/ImgH&#x2264;1.25.

Optical imaging lens assembly

An electrical socket includes a magnet connected to a shield. The shield blocks access to receptacles of the socket when the magnet is at a rest position but moves away and allows access to the receptacles when the magnet is moved away from its rest position. The magnet is attached to a spring so that the spring pulls the magnet toward the rest position. A plug includes a plug magnet to attract the socket's magnet. When the plug is brought close to the socket, the socket magnet is pulled away from the rest position, moving the shield away and allowing the plug to be inserted.
