The invention is, furthermore, a crimping device for securing an optical conduit into a connector part, a push-out device for removing an optical conduit from a connector part, and a light blocking element for a connector part.

A field-assembly optical connector includes an inner sleeve module, a connector frame housing the inner sleeve module, and a cable boot coupled to the inner sleeve module to protect a sheath of an optical fiber. The inner sleeve module includes a sleeve body having a sleeve, an intermediate connector fitted on the sleeve body and having protrusions, a spring fitted on a threaded portion of the sleeve body, a fixing ring screwed to the threaded portion of the sleeve body, and a ferrule stub inserted into the sleeve body through the fixing ring. A cable boot is fixed to the sleeve body and is coupled to the intermediate connector to be moveable within a predetermined range.

An optical fiber connector according to the present disclosure includes an inner housing, a first outer housing and a second outer housing. The inner housing has a first wall, a second wall, a third wall and a fourth wall, wherein the first wall faces the third wall and connects with the second and fourth walls. The first outer housing is positioned to surround the inner housing. The second outer housing is positioned to surround the inner housing and engage the first outer housing. A key arm extends from the second outer housing and is configured to position on the first wall or the third wall of the inner housing. When the inner housing is inserted into an optical fiber adapter, the key arm is inserted into the key recess of the optical fiber adapter.

A connector-equipped plug which has a built-in connector to be inserted into and connected to an adaptor inside a receptacle and is to be connected to the receptacle includes an inner housing that is located on a rear end side in an insertion direction of the connector to hold the connector and has a plurality of protrusions formed on an outer peripheral surface, a spring that pushes the inner housing in the insertion direction, and a tubular outer shell member that has a plurality of recesses formed in an inner peripheral surface. The connector has a tapered shape on a distal end side in the insertion direction, and the recesses are each formed such that the recess decreases gradually in width in the insertion direction and such that a bottom surface gradually approaches a central axis of the outer shell member.

It is an object of the present invention to accurately maintain a positional relationship between a lens held in a holding member and an optical fiber without requiring any complicated operation. The invention includes a holder (11), at one end of which a housing section (11c) that houses a ball lens (12) is formed and at the other end of which an insertion hole (11a) for inserting an optical fiber (13) is formed, and a magnet (14) provided outside in a direction crossing a housing direction of the ball lens at the one end of the holder, in which the magnet generates an attracting force for aligning a center of the ball lens with a center of an optical element provided in a coupling target.

An optical fiber connector, including a flat drop cable, a connector sub-assembly comprising one end fastened to the flat drop cable, a coupling shaft, which is step-shaped and includes a flange and a plastic body, where one end of the plastic body is provided with an internal thread configured to be connected to an external thread of the connector sub-assembly, and the flange is provided with at least one hook groove, an inner sleeving element configured to accommodate the connector sub-assembly, where one end of the inner sleeving element is higher than an end surface of a ceramic ferrule of the connector sub-assembly, and the inner sleeving element is provided with an open slot, and an outer sleeving element, where the outer sleeving element is configured to sleeve the inner sleeving element, and capable of sliding forwards and backwards relative to the inner sleeving element.

Aspects of the present disclosure relate to a multi-fiber fiber optic connector having a connector body, a multi-fiber ferrule supported at a distal end of the connector body, a spring for biasing the multi-fiber ferrule in a distal direction and a spring push retaining the spring and the ferrule within the connector body. The spring push including oppositely positioned spring support shelves that provide spring seating and provide spring stability during side loading.

A multiple fiber push-on (MPO) optical connector is provided having a ferrule configured to house multiple optical fibers and including a stepped portion extending from at least one pair of opposing exterior surfaces of the ferrule. A one-piece housing-backpost is provided having a distal end in a connection direction and a proximal end in a cable direction. The one-piece housing-backpost is configured to receive a ferrule spring and the ferrule from the distal end. The housing-backpost includes at least one resiliently-deformable ferrule-retaining protrusion extending from a sidewall to engage the corresponding stepped portion of the ferrule. The resiliently-deformable ferrule-retaining protrusion is configured to deform towards the housing-backpost interior sidewall as the ferrule is inserted from the distal end and to extend outward against the stepped portion of the ferrule when the ferrule is seated in the housing-backpost to maintain the ferrule in the housing-backpost.
