  • Patent number: 11415748
    Abstract: A fibre optic cable stripper, comprising an alignment and fixing element, a rotational adjuster, and a lateral stripping and removing element is provided. The alignment and fixing element, aligning and fixing the fibre optic cable, comprises an alignment and threaded sleeve portion and a fixing portion. The rotational adjuster, sleeved on the alignment and threaded sleeve portion, rotatably moves back and forth thereon. The lateral stripping and removing element, cutting and stripping and rotating the rotational adjuster, comprises an enabling gap portion and a lateral sleeve portion. The lateral sleeve portion is mounted to the rotational adjuster and the enabling gap portion strips at least two gaps through to an end of the fibre optic cable having a preset depth via rotatable movement of the rotational adjuster. The preset depth is different depths defining different diameter sizes of the fibre optic cable.

  • Publication number: 20210364723
    Abstract: A fibre optic pulling grip assembly, comprising a sleeve, connection sleeve, swivel pulling eye unit, fitting, clamp, and a securing unit is provided. The sleeve has a sleeve coupling portion and sleeve body. The connection sleeve has a connection sleeve head and connection sleeve body. The swivel pulling eye unit has a pulling eye swivel portion and pulling eye body. The connection sleeve body is configured for fixed assembly of the pulling eye body therewithin, the sleeve coupling portion is configured for fixed assembly of the connection sleeve body therewithin, and the fitting is configured for fixed assembly of the sleeve coupling portion therewithin. The clamp has a clamp securing portion and clamping portion. The securing unit moves longitudinally toward the clamping portion, such that the fitting is moved to assemble to the sleeve coupling portion, applying pressure to the sleeve coupling portion supported by the connection sleeve body.

  • Patent number: 8262409
    Abstract: A coaxial cable connector includes: a connection terminal having a base section, a first extension section upward extending from a first edge of the base section, a second extension section upward extending from a second edge of the base section and spaced from the first extension section; an insulating member having an insulating main body for supporting the base section of the connection terminal; and a case for supporting the insulating main body of the insulating member. The first and second extension sections are bendable by means of a bending force applied to the insulating member and the case, whereby the first and second extension sections are urged to securely clamp an internal conductor of a coaxial cable at multiple points so as to electrically connect the connection terminal with the internal conductor of the coaxial cable.

  • Patent number: 8137134
    Abstract: A coaxial cable connector includes: a connection terminal having a base section and a pair of resilient clamping plates upward extending from two sides of the base section; an insulating member having an insulating main body for supporting the base section of the connection terminal, an insulating bendable section upward extending from one side of the insulating main body, and a pair of projections formed on two sides of the insulating bendable section corresponding to the resilient clamping plates; and a metal case for supporting the insulating main body of the insulating member. When the insulating bendable section is bent downward, the projections compress the resilient clamping plates to move inward so as to securely clamp an internal conductor of the coaxial cable. Accordingly, the resilient clamping plates of the connection terminal are electrically connected with the internal conductor of the coaxial cable.
