Preferably, the spring clip comprises a fixing portion, the fixing portion is -shaped, the fixing portion is matched with the shell and the socket, a clamping portion arched inwards is arranged at an opening of the fixing portion, and the clamping portion has elasticity.
Preferably, the distance between the clamping part and the top end of the fixing part is the same as the length of the optical lens.
Preferably, the fixing part is provided with a fixing piece protruding outwards, and the fixing piece is fixed with the shell.
Preferably, a part of the inner side of the socket is further provided with a fixing table protruding inwards, and the fixing table and the fixing piece are mutually clamped and fixed.
Preferably, the clamping part is formed by bending an inward arched spring piece, one end of the clamping part is connected with the fixing part, the middle part is in an inward arched bending shape, and the other end of the clamping part is in contact with the socket.
Preferably, the free end of the cover body is provided with a rotating shaft protruding outwards, and the rotating shaft is detachably buckled with the shell.
Preferably, the fastener is disposed opposite to the clamping portion, and when the cover is closed, the fastener extends into the curved middle portion of the clamping portion, and the fastener is used for limiting deformation of the clamping portion.
Preferably, the cover body is arranged above the shell in a reversible manner, and the socket and the light plug are visible when the cover body is turned and opened.
Compared with the prior art, the invention has the beneficial effects that: 1) The optical fiber plug does not need to be matched with the lens in a blind way, so that the optical fiber plug can be easily inserted and can be observed whether the optical fiber plug is inserted in place or not under the visible condition. 2) The optical fiber plug can be locked by the reversible cover body and cannot be retracted. 3) The spring force exerted on the fiber optic plug acts on the lens and since the spring clip can twist around the lens, all of the force can be balanced around the lens, no directional imbalance force will be exerted at the junction of the lens and the circuit board.
