Abstract

A feedthrough coaxial cable connector includes a tubular mandrel body dimensioned to be pressed between a foil-bonded dielectric core and other elements of an outer conductor of the prepared end of the cable. The body has cable engagement surface which defines a knife edge projection therearound for engaging an outer conductor of the cable by creating shear stresses therein without actually shearing the outer conductor. A tubular shank portion extends from the cable engagement surface portion to a radial wall portion, and a jack engagement portion is coaxial about the exposed central conductor. The jack engagement portion achieves a tight friction fit upon a jack and may be formed as an inside compression collet. A radial compression providing structure causes an inside surface region of the outer conductor to bear directly against and bend over the knife edge portion. Preferably, a slideable shell is slideably positionable generally away from a connector end facing the outer surface of the jack to enable the jack engagement portion of the connector to slide over the outer surface of the jack, and slideably positionable toward the connector end so as to radially compress the radially diverging jack engagement portion against the outer surface of the jack to secure the connector thereto. A kit of parts including an expandable installation tool enables proper assembly of the cable connector without special skills or tools.

Description

[Detailed description of the invention] Feedthrough Coaxial Cable Connector Field of Invention The present invention relates to connectors for coaxial cables. In particular, the invention provides for example , a type of coaxial cable typically used indoors for broadband radio frequency signal transmission. Very inexpensive, easy-to-install feedthrough connector for - related.

Background of the invention Coaxial cable transmits broadband radio frequency ffRF, such as television and radio signals. J) Widely used for the transmission of information. Coaxial cable typically consists of two conductor, i.e. the center axis conductor and the outer conductor substantially coaxial with respect to the inner center conductor. and provide. The center conductor is typically completely surrounded by the outer conductor and is A low-loss, high-dielectric insulating material, such as foam plastic, separates the two conductors.

Although not required, an outer insulating jacket is usually placed over the outer conductor. , electrical insulation and physical protection of the cable is provided. The outer conductor is a single piece Alternatively, it may be a composite of a plurality of layered members such as conductive foil or wire braid.

One element of the composite outer conductor structure is applied to the outer surface of a low loss high dielectric constant insulating material It may be a conductive film or coating film.

Relatively large diameter semi-rigid coaxial cables service cable network signals. power is transmitted to a drop box location close to the subscriber's premises. outdoors in cable television transmission networks as power transmission conductors for Widely used. Service drop at subscriber's premises A small, relatively flexible Coaxial cable is used.

A connector is provided for connecting the cable in an outdoor environment. Like that Connectors must provide a reliable signal-tight electrical connection. as well as a secure leak-proof seal to prevent moisture ingress into the cable. A physical connection must also be provided. Fitting such a connector is standard. Typically, cable ends such as core rings or stripping of a dielectric insulator core at a predetermined distance Requires preparation and then using special tools depending on the conductor/cable design. Conductor assemblies may be installed and tightened by skilled personnel with or without hands. . Typically, connectors in outdoor environments will run coaxially on the exposed end of the center conductor. providing a central connector member that is secured to the central connector; In this way, one part of the center connector , greatly contributes to fixing the connector structure of the prepared cable end.

Typically, power transmission network operators are responsible for Subscribers do not want to attach connectors to cables due to tools that allow unauthorized persons to touch the system power transmission box, service drop, etc. It is often used by trained wearers to eliminate

The opposite situation often exists at the subscriber's premises. Typically, subscribers Or typically mounted on a wall plate in another indoor location and outside Extending service cables must be interconnected and connected to the outlet jack. Not owning many appliances.

For example, television sets, video cassette recorders (rVCRJ) and A connection is required between the stereo FM receiver jack and the service jack. Ru.

To achieve this necessary connection, typically small diameter (approximately 1/4 inch or less) (or less) flexible coaxial cable is used.

These coaxial cables typically have a solid wire center conductor, a foam core, or a foam core. an outer composite conductor formed from an inner aluminum coating on top, - or more a layer of mesh aluminum wire plaid, and - or more Contains an aluminum foil layer.

The outer composite conductor is typically made of insulating material to complete the coaxial cable structure. - covered by a plastic outer insulation jacket consisting of or more layers; There is. The dimensions of such coaxial cables can vary depending on the type and its material . Also, cable characteristics vary depending on the type and material, as well as factors such as environmental temperature. can also change. When the environmental temperature is low, polymer cable materials become very stiff ( Difficult to handle during connector installation procedure. We also have foil coated inner insulation core may vary in diameter from about 0.140 inch to about 0.200 inch.

Consumers can obtain standard length small diameter cables with factory-installed connectors. Now I can do it. Also, connectors can now be used for attachment. However, fitting these connectors onto prepared cable ends typically requires Crimp tool to crimp the retaining cap or to extend the retaining slip ring. For tightening pressure nuts that hold connectors or connectors at cable ends, etc. Requires tools. Some connectors for indoor service are screwed Provides and requires a pressurizing action between the face of the jack and the body of the connector, which It actually involves tightening the threaded nut of the connector onto the outer thread of the jack. more achieved.

Connectors for indoor services are independent of the connectors provided for connection If the center conductor of the cable is not present and the center conductor of the cable presents a member of the connection mechanism. It is also known as a "feed-through" connector.

The center conductor is typically fitted with a jack glue septacle member. Center fastening mechanism Such members, sometimes referred to as connector assemblies, if present, and the center conductor of the coaxial cable.

If it's a feedthrough connector, place the feedthrough connector there The exposed end of the solid wire center conductor of the coaxial cable is the center fastening mechanism of the jack. directly fitted. The center conductor of a coaxial cable is a feed-through connector. Because they are not mechanically maintained mated and their connectors are to feed or connect to the jack and thereby engage the central fastening mechanism of the jack. It only serves to place the exposed center conductor in the Conventional technologies that provide a Extended and reliable use in the field has been found to be unsatisfactory.

This also applies to individual trials made with the prior art; until now, users have not been able to Easy to assemble and connect to cables with simple operation without any tools or techniques Can be installed securely and conveniently for long periods of time on jacks that are combined for use. Very inexpensive feed-through coaxial cable connectors exist that provide a I didn't.

Coax cable for attaching a feedthrough connector to a prepared cable end. Various techniques can be found in the field of bull connectors. one representative An example is the Quackenbush U.S. Patent No. 3,781. , No. 762. In this patent, a tubular connector body has an annular shape. Including flare.

This body is large enough to fit just between the insulated core and the outer conductor at the end of the prepared cable. The exposed end of the center conductor is aligned with the center conductor. Annular flare of tubular body The outer conductor expands when the main body is pushed between the core and the outer conductor during installation. Ru. A cylindrical ferrule, such as a split ring or talin ring, then an annular Attach the flare to the inner body. The Quackenpush device The connector appears to provide a good electrical and mechanical connection to the body.

However, the Quackenpush connector requires special features to attach the clamping cap. It cannot be easily attached to the prepared cable end without another tool.

As mentioned above, another feedthrough connector connects a threaded nut to the jack. It relies on the compression fit achieved by tightening.

To tighten the connector, press the nut against the outer conductor against the connector body. This secures the connector to the cable. One disadvantage of this method is that nuts If the connector does not tighten into the threaded jack, or if one end of the connector Undesirably, slight pulling or twisting may cause the This is when the connector separates from the cable.

Other more common means of coaxial cables include means of mating the exposed end of the center conductor Can be found in the connector field. For example, British patent 621,45 9 is a tubular connector to be inserted between the insulated core and the outer conductor of the coaxial cable One body is listed.

An annular flare or expansion region expands the outer conductor of the cable and extends longitudinally. The split cap tube is pushed over the coaxial cable end in the expansion area. Enclose the body and press the cable against the expansion area to make electrical and mechanical connections. Improve bonding. After the cap is in place, it can be fixed to the connector body. Includes fingers that allow the

Provides a directional band, but does not allow the long ferrule or other structure of the connector to No fit is provided between the cable on the rear side of the raised portion on the outside of the body.

Obviously, Pagner's The patent claims that by the method of crimping or ponding on the exposed end of the center conductor of the cable A fixed center connector structure is taught.

Additional retention with a central connector structure as described in the Bugner patent If unaided, tensile or compressive stresses on the coaxial cable can cause If the motor is screwed onto the jack, the tends to separate from the connector. Also, any sagging in the cables, especially In an indoor environment such as a home, there is a tendency to stretch the outer conductor; loss of effective electrical contact with the ridge on the part and/or failure at the connector. May provide the necessary signal leakage path.
