Description

Coaxial connector of corrugated cable and method of coupling coaxial cable

The present invention generally relates to coaxial cable connectors, and more particularly to coaxial cable connectors having helical grooved outer conductors.

A coaxial cable is characterized by having an inner conductor, an outer conductor, and an insulator between the inner and outer conductors. The inner conductor can be hollow or solid. A connector is attached to the end of the coaxial cable to electrically and mechanically couple the coaxial cable.

Coaxial cable connectors have been used throughout the coaxial cable industry for many years, including coaxial cable connectors with helical grooved outer conductors. Accordingly, we have an ongoing need for improved high performance coaxial cable connectors.

One aspect of the invention relates to a coaxial cable connector designed to be electrically coupled to a coaxial cable. The coaxial cable includes a center conductor, a cable jacket, and an outer conductor. The coaxial cable connector includes a body including a front end, a rear end, and an internal opening. The coaxial cable connector also includes a coupling nut rotatably secured to the front end of the body. In addition, the coaxial cable connector includes a rear side nut that is rotatably secured to the rear end of the body. The rear side nut includes an internal opening. The coaxial cable connector further includes an internal fluted member at least partially within the internal opening of the body. The inner fluted member includes a front end, a rear end, and an inner fluted area. In addition, the coaxial cable connector includes an inner clamping member at least partially within the inner opening of the rear side nut. The axial advancement of the rear side nut in the direction of the front end of the body results in at least a portion of the inner clamping member being radially compressed inwardly.

In another aspect, the invention includes a coaxial cable connector in which the body and internal corrugated members are combined into one individual as described above. Specifically, the coaxial cable connector includes a body including a front end, a rear end, and an internal grooved area. The coaxial cable connector also includes a coupling nut that is rotatably secured to the front end of the body. In addition, the coaxial cable connector includes a rear side nut that is rotatably secured to the rear end of the body. The rear side nut includes an internal opening. The coaxial cable connector further includes an internal fluted member at least partially within the internal opening of the rear side nut. The rear side nut advances axially in the direction of the front end of the body, causing at least a portion of the inner clamping member to compress radially inwardly.

In yet another aspect, the present invention provides a method of coupling a coaxial cable and a coaxial cable connector. The method includes inserting one end of the coaxial cable into one of the two types of coaxial cable connectors described above. In addition to this, the method includes the rear side nut axially advancing in the direction of the front end of the body, causing at least a portion of the inner clamping member to compress radially inwardly.

The preferred embodiment of the present invention can provide at least one benefit including, but not limited to, simplified connector mounting, simplified connector component geometry, positive mechanical attraction of cables along multiple points of contact, reduced installation time , without the use of special tools for installation or removal, and/or improved electrical performance (common path distortion) due to stable connector/cable connections.

Other features and advantages of the invention will be apparent from the description and appended claims.

The prior general description and the following detailed description are to be considered as illustrative and illustrative, and The accompanying drawings will further provide an understanding of the invention, as well as a

Reference will now be made in detail to the preferred embodiments embodiments

A coaxial cable connector designed to be electrically coupled to a coaxial cable, the coaxial cable including a center conductor, a cable jacket, and an outer conductor, the connector including: a body including a front end, a rear end, and an inner portion a coupling nut rotatably fixed to the front end of the body; a rear side nut rotatably fixed to the rear end of the body, the rear side nut including an internal opening; and an internal groove member at least partially located inside the body Within the opening, the inner fluted member includes a front end, a rear end, and an inner fluted region; and the inner clamping member is at least partially located within the inner opening of the rear side nut; wherein the rear side nut is oriented at the front end of the body Advancing toward the ground results in at least a portion of the inner clamping members being radially compressed inwardly. A coaxial cable connector according to the first aspect of the invention, wherein the inner groove region comprises an inner opening between the rear end of the inner groove member and the inner groove region. A coaxial cable connector according to claim 2, wherein the inner clamping member is at least partially located within the inner opening of the inner member during the first phase of assembling the coaxial cable. A coaxial cable connector according to claim 1, wherein in the first stage of assembling the coaxial cable, the inner clamping member includes a rear end that abuts the inner groove member toward the front annular shoulder. According to the coaxial cable connector of claim 1, wherein the inner clamping member contacts the inner groove member in the first stage of assembling the coaxial cable, Cable jacket and rear nut. A coaxial cable connector according to claim 1, wherein the rear side nut does not contact the inner groove member in the final stage of assembling the coaxial cable. A coaxial cable connector according to claim 1 wherein the connector includes a contact point comprising a plurality of contact tines to establish mechanical and electrical communication with the central conductor of the coaxial cable. A coaxial cable connector according to claim 1, wherein the connector comprises an insulator between the contact point and the body. A coaxial cable connector according to the first aspect of the invention, wherein the connector comprises a ring between the inner groove member and the front end of the body. A coaxial cable connector according to claim 9 wherein the ring includes a tapered protrusion and the outer conductor of the coaxial cable is sandwiched between the inner groove member and the tapered protrusion at the final stage of assembling the coaxial cable in. A method of coupling a coaxial cable, the coaxial cable comprising a central conductor, a cable jacket, and a conductor external to the coaxial cable connector, the method comprising: inserting the prepared end of the coaxial cable into the coaxial cable connector, The coaxial cable connector comprises: a main body including a front end, a rear end, and an inner opening; a coupling nut rotatably fixed to the front end of the main body; a rear side nut rotatably fixed to the rear end of the main body, the rear side screw The cap includes an inner opening; the inner groove member is at least partially located within the inner opening of the body, the inner groove member includes a front end, a rear end, and an inner groove region; and the inner clamping member is at least partially located at the rear side nut Inside the internal opening; And the rear side nut advances axially in the direction of the front end of the body, thereby causing at least a portion of the inner clamping member to compress radially inwardly. The method of claim 11, wherein the inner corrugated member comprises an inner opening between the rear end of the inner corrugated member and the inner corrugated region, and the inner clamping member is at least partially located within the inner corrugated member The internal opening of the area is in the final stage of assembling the coaxial cable. The method of claim 11, wherein the inner clamping member contacts the body, the cable jacket, and the rear side nut in the final stage of assembling the coaxial cable. The method of claim 11, wherein the rear side nut does not contact the inner fluted member during the final stage of assembling the coaxial cable.
