Abstract: An optical connector comprises one or more optical cables disposed within a housing. Each optical cable includes an array of at least one optical waveguide and at least one optical ferrule attached to the array of optical waveguides. The housing includes a first housing portion and a second housing portion engaged with the first housing portion. The second housing portion comprises at least one carrier and one frame. The carrier and frame of the second housing portion are configured to support the one or more optical cables. The first housing portion and the second housing portion are configured such that mechanical engagement of the first housing portion with the second housing portion moves the carrier relative to the frame. Movement of the carrier relative to the frame causes a bend in each optical waveguide and rotation of each ferrule. The bend provides a predetermined spring force of the optical waveguides at a predetermined angle of the ferrule.

Abstract: A connector for establishing electrical connections with a PCB comprises first and second sets of contact pads arranged in first and second rows on a same surface of the PCB. The connector includes a first set of elongated contacts, a second set of elongated contacts, and a contact block. The first set of contacts have contact surfaces that form a first row of contact surfaces configured to make and break electrical connectivity with the first set of contact pads of the PCB. The second set of contacts have contact surfaces that form a second row of contact surfaces configured to make and break electrical connectivity with the second set of contact pads of the PCB. The contact block supports the first and second sets of contacts and causes the contact surfaces to wipe against the first and second sets of contact pads when making and breaking electrical connectivity therewith.

Abstract: An optical ferrule configured to move along a mating direction to mate with a mating optical ferrule. The optical ferrule includes an attachment portion for receiving and securing one or more optical waveguides. First and second engagement portions are formed integrally with the optical ferrule and spaced apart from each other along the mating direction. First and second engagement portions are formed integrally with the mating optical ferrule and spaced apart from each other along the mating direction. When the optical ferrule mates with the mating optical ferrule, the first and second engagement portions of the optical ferrule engage the respective second and first engagement portions of the mating optical ferrule. The engagement of the engagement portions of the optical ferrules prevents each of the optical ferules from moving relative to the other optical ferrule along at least mutually orthogonal first and second directions orthogonal to the mating direction.

Abstract: An optical connector (100) comprises one or more optical cables (110) disposed within a housing (120). Each optical In cable (110) includes an array of at least one optical waveguide (111) and at least one optical ferrule (112) attached to the array of optical waveguides (111). The housing (120) includes a first housing portion (121) and a second housing portion (122) engaged with the first housing portion (121). The second housing portion (122) comprises at least one carrier (130) and one frame (140). The carrier (130) and frame (140) of the second housing portion (122) are configured to support the one or more optical cables (110). The first housing portion (121) and the second housing portion (122) are configured such that mechanical engagement of the first housing portion (121) with the second housing portion (122) moves the carrier (130) relative to the frame (140). Movement of the carrier (130) relative to the frame (140) causes a bend in each optical waveguide (111) and rotation of each ferrule (112). The bend provides a predetermined spring force of the optical waveguides (111) at a predetermined angle of the ferrule (112).

Abstract: An optical connector includes a housing having a resilient member and an optical ferrule. The optical ferrule includes a plurality of attachment areas for receiving and securing a plurality of optical waveguides and a light redirecting side for changing a direction of light received from an optical waveguide. The optical connector is configured such that when an optical waveguide is received and secured in any of the attachment areas and light from the optical waveguide propagates along an optical path, the resilient member is not in the optical path. When the optical ferrule mates with a mating optical ferule, the resilient member is resiliently deformed to resiliently force the optical ferrule against the mating optical ferrule.

Abstract: An optical connector assembly includes first and second optical ferrules. Each of the first and second optical ferrules includes a front portion extending forwardly from a rear portion. The rear portion includes a top side and a bottom side. The bottom side of the rear portion defines a recessed portion. The first and second optical ferrules mate with each other such that the front portion of each of the first and second ferrules is disposed in the recessed portion of the other one of the first and second ferrules. Discrete retainers are assembled to opposite ends of the mated first and second ferrules. Each of the retainers defines a resilient portion resiliently forcing the front portion of one of the first and second mated ferrules against the other one of the first and second optical ferrules.
