COAXIAL CONNECTOR WITH INSULATOR MEMBER INCLUDING ELONGATE HOLLOW CAVITIES AND ASSOCIATED METHODS}
TECHNICAL FIELD The present invention relates to the field of cables and connectors, and more particularly to a connector of a coaxial cable and a method of manufacturing the same.
Coaxial cables are widely used to transmit high frequency electrical signals. Coaxial cable has a relatively high bandwidth, low signal reduction, is mechanically robust and relatively low cost. One particularly advantageous use of coaxial cables is to connect the electronics of a cellular or wireless base station to an antenna mounted on top of a nearby antenna tower. For example, a transmitter located in an equipment shelter may be connected to a transmit antenna supported by the antenna tower. Likewise, the receiver is also connected to its associated receiver antenna by a coaxial cable path.
Typical installations have a relatively large diameter cable extending between the device shelter and the top of the antenna tower to reduce signal loss. For example, Hickory, N.C., ComScope, Inc., and the assignee of the present invention, have described their CellReach? Provide coaxial cable. The cable includes a smooth wall outer conductor that provides better performance than other cable types. The flat outer wall structure makes it easier to attach the connection portion to the cable end as compared to other coaxial cable types, such as, for example, including corrugated outer conductors.
A typical coaxial cable connector for the coaxial cable includes a tubular housing or body for making an electrical connection to the cable outer conductor and a center contact for making electrical contact to the inner conductor of the coaxial cable. The central contact may include a tubular rear end to receive the inner conductor of the coaxial cable. The insulator assembly supports the center contact concentrically in the housing. The insulator assembly typically includes a number of cooperating parts.
A typical connector is disposed on the end of the outer conductor and may include a gripping member or ferrule adjacent to the outer insulating jacket portion of the coaxial cable. The ferrule is axially advanced in the housing as a back nut is tightened on the rear end of the housing. For example, one or more O-rings are installed in the connector to seal the connector around to prevent water from entering.
Representative patents relating to coaxial cable connectors are described, for example, in US Pat. No. 6,396,367 B1 to Rosenberger; US Patent Application No. 6,024,609 to Kooiman et al .; US Patent Application No. 6,607,398 B2 to Henningsen; And US Patent Application No. 6,217,380 B1 to Nelson et al. The entire contents of each of these patents are incorporated herein by reference.
US Patent Application No. 7,011,546 to Vaccaro, assigned to the assignee of the present invention and incorporated herein by reference, discloses a connector having significant advantages over the prior art. The connector includes a housing, a bag nut threadingly engaging a rear end of the connector housing, a ferrule that grips the end of the coaxial cable forward into the connector as the bag nut is tightened, and an inner portion of the connector housing. It includes an insulator member disposed. The insulator member also has a bore extending therethrough, the rear portion from the rear portion to support the front portion, the rear portion, the ring portion connecting the front portion and the rear portion together, and the outer conductor inner surface of the coaxial cable end. And extending tubular outer conductor support. The ring portion may have a reduced strength portion bounded by a crush zone to facilitate movement of the rear portion towards the front portion as the bag nut is tightened on the connector housing.
ComScope has made another connector similar to Vaccaro's patent in which the insulator member 5 is adjusted to match the impedance between the connector and the cable end. More particularly, as will be understood with respect to FIG. 1, the prior art insulator member 5 includes a front portion 7 comprising a pair of longitudinal passages 8a, 8b through it for impedance matching. ). The insulator member 5 also includes a tubular outer conductor support comprising sidewalls 6 initially formed to have an inner diameter d1. In the subsequent matching steps, two further enlarged diameters d2 and d3 are formed in the side wall 6 to adjust the impedance. In other words, after initial molding to form the insulator member 5, the two enlarged diameters d2 and d3 are produced by a further machining step. These additional manufacturing steps can increase manufacturing cost and / or complexity.
In view of the foregoing background, it is therefore an object of the present invention to provide a coaxial connector having an insulator member which can be easily manufactured and which effectively matches the impedance between the coaxial cable and the connector.
These and other objects, features, and advantages according to the present invention are provided by a coaxial cable connector comprising an insulator member having a front portion and a rear portion extending rearward from the front portion. The rear portion may comprise a tubular outer conductor support for supporting an outer conductor inner surface of the coaxial cable end. The tubular outer conductor support may also include sidewalls having a plurality of hollow cavities disposed at intervals extending therein. These cavities can advantageously provide impedance matching and can be readily formed during the manufacture of insulator members such as, for example, moldings.
The connector may further comprise front and rear ends and an inner portion therebetween, and a bag nut screwed to the rear end of the connector housing. The insulator member may be disposed in an inner portion of the connector housing. Contacts may be involved in the bore of the insulator member to connect to the inner conductor of the coaxial cable end.
The rear portion of the insulator member may further comprise a rear disk portion, the rear disk portion coupling a tubular outer conductor support to the front portion, a plurality extending through it in direct communication with the respective hollow cavities of the tubular outer conductor support. Has openings. In some embodiments, each of the plurality of elongate hollow cavities can only extend partly to the sidewall of the tubular outer conductor support. Each hollow cavity may have a cylindrical shape, for example, to facilitate molding.
The insulator member may have a longitudinal axis, and the hollow cavity may be a long hollow cavity extending generally parallel to the longitudinal axis of the insulator member. The elongate hollow cavity may be spaced at the same angle with respect to the longitudinal axis of the insulator member. In addition, the sidewalls of the tubular outer conductor support may have a consistent uniform inner diameter and / or a consistent uniform outer diameter.
The connector may further include a ferrule that grips the coaxial cable end to advance the coaxial cable end to the connector housing as a bag nut is tightened on the rear end of the connector housing. The front part and the rear part of the insulator member together with the plurality of hollow cavities can be integrally molded as a monolithic unit. The front portion of the insulator member may include a front disk portion and a ring portion coupling the front disk portion to the rear portion.
The method aspect is for manufacturing a coaxial cable connector. The method may include installing a connector housing, and forming an insulator member for placement within the connector housing. The insulator may comprise a front portion and a rear portion extending rearward from the front portion and including a tubular outer conductor support portion for supporting an inner surface of the outer conductor of the coaxial cable end.
