Coaxial cable connector

BACKGROUND OF THE INVENTION
Field of the Invention

Example embodiments relate generally to the field of communications and data transmission and, more particularly, to coaxial cable connectors.

DESCRIPTION OF THE RELATED ART

TV service types are dominated by cord connected services. These cord connected services utilize coaxial cables for connection, employing connectors such as twistable F-type connectors. Twistable F-type connectors are used for connection with cable TV decoders, digital video recorders and DVD recorders, satellite receivers, video game systems, distribution amplifiers or signal splitters, and switching boxes etc., having a mounting means built therein.

Conventional coaxial cable connectors generally comprise a connector body having a post which is able to house a coaxial cable therethrough, a nut, rotatably coupled to the post, mounting the coaxial cable connector to a rack, casing, apparatus or device having a mounting means built therein, and an annular flange, between the post and nut.

An o-ring may also be placed between the post and nut at a rotatable portion therebetween, for waterproof sealing.

The post of the coaxial cable connectors, generally comprise a coaxial cable receiving end, receiving a coaxial cable therethrough and a coaxial cable connecting end, opposite thereto. The nut of the coaxial cable connectors, generally further comprise internal threads, at the coaxial cable connecting end, having a width compatible for mounting the coaxial cable connectors to an interface port of the rack, casing, apparatus or device having a mounting means built therein.

Conventional coaxial cable connectors may further comprise a sleeve, for securing the coaxial cable positioned within the connector body of the coaxial cable connector to the interface port. The sleeve is basically formed of an elastic plastic material and is slidably engaged to the connector body of the coaxial cable connector. However, often the coaxial cable connectors are not properly mounted to the interface port.

Over time, the coaxial cable connectors may not fully engage with and be tightened to the interface port. Thus, proper electrical mating of connector components with the interface port would not occur. After tightening, the coaxial cable connector may undergo complete or partial pretension loss caused by dynamic stresses resulting in the loosening or relative movements resulting in the unscrewing from the interface port, causing loss of component abutment and proper electrical mating.

The coaxial cable connectors may be over-tightened to the interface port. Thus, proper electrical mating of connector components with the interface port would also not occur. After being over-tightened, electrical mating may be faulty because the connector components are caused to yield and/or move out of proper physical connection with the interface port. This is generally more common for coaxial cable connectors not having o-rings placed between the post and nut at rotatable portions therebetween, where waterproof sealing may not be required for coaxial cable connectors being used indoors.

The center conductor 1 extends flush with the proximal nut interior opening surrounded by the threaded portion 746 of the nut 74.

FIG. 14 is a schematic perspective first view of yet another alternative coaxial cable connector without a sleeve, according to an example embodiment. Referring to FIG. 14, and referring to FIGS. 10 to 13C and FIGS. 8A, 8B, 9C and 9D, in the yet another alternative embodiment, the coaxial cable connector comprises the sleeve 18 and the alternative post 50 of FIGS. 10 to 13C, and the another alternative nut 74 of FIGS. 8A, 8B, 9C and 9D.

The another alternative nut 74 further comprises a threaded portion 746 surrounding the proximal nut interior opening.

In the yet another alternative embodiment of the coaxial cable connector, the alternative post 50 is assembled to the nut 74 via the distal nut interior opening 742. A diameter of the distal nut interior opening 742 is greater than a diameter of the proximal post engagement portion 547, but smaller than an outer surface diameter of the outer proximal annular outward protrusion 526. The proximal outward protrusion shoulder 527 is flush with the distal nut base and the proximal post engagement portion 547 extends further than a reference plane normal to the proximal inner protrusion shoulder 741, wherein the proximal post engagement portion 547 is annularly outwardly bent forming a proximal post rolled rim 504. The distal annular inward protrusion 744 of the nut 74 is between the proximal post rolled rim 504 and proximal annular outward protrusion 526 of the post 50. The nut 74 is assembled to the proximal sleeve interior portion 186a of the sleeve 18 via the distal sleeve interior opening 186. In some embodiments, the shape of the distal sleeve interior opening 186 is polygonal-shaped. Following assembly, a plurality of deformed indentations is formed on an inner surface of the sleeve 18 via the plurality of engagement protrusions of the nut 74.

The depth, pitch (P), and amount of plurality of peaks, are configured such that the nut 74 may be conveniently slip-on assembled to the sleeve 18 and following deformation of the inner surface of the sleeve 18 via the plurality of peaks 751 of the nut 74, the nut 74 is fixedly gripped and mounted to the sleeve 18, such that unmounting and/or rotational slippage due to, as an example, dynamic stresses or screwing and unscrewing of the coaxial cable connector is hindered. The depth, pitch (P), and amount of plurality of peaks, may be configured such that a greater amount of inner surface deformation is achieved, increasing ploughing friction, resulting in a higher friction value.

In the yet another alternative embodiment of the coaxial cable connector, each of the first and second plurality of grooves 753, 754 of the nut 74 comprise a first groove surface, a second groove surface, and a groove line formed at each respective juncture of the first and second groove surfaces. In an alternative embodiment, the intersections of the first and second plurality of grooves 753, 754 form a plurality of pyramids 752 on each of the plurality of crests 750 of the nut 74, whereby each of the pyramids 752 include first opposed lateral surfaces 753a (proximal facing), 753b (distal facing) formed by the first groove surfaces and second opposed lateral surfaces 754a (proximal facing), 754b (distal facing) formed by the second groove surfaces.

In the yet another alternative embodiment of the coaxial cable connector, the sum of the magnitudes of the first and second helix angles of the nut 74 are 90° degrees or less. In some embodiments, the magnitudes of the first and second helix angles of the nut 74 are the same. In some embodiments, the magnitudes of the first and second helix angles of the nut 74 are different. The magnitudes of the first and second helix angles determine the amount of the plurality of peaks 751 of the nut 74 and formation of the plurality of deformed indentations on the inner surface of the sleeve 18. The magnitudes are configured such that a greater amount of inner surface deformation is achieved, increasing ploughing friction, resulting in a higher friction value.

In some embodiments, the slopes forming included angles (8) of the first and second opposed lateral surfaces 753a, 753b, 754a, and 754b are different, respectively. As an example, and not to be limiting, angles of lateral surfaces relative to nearest surfaces of each of the plurality of crests 750 of the proximal facing first and second opposed lateral surfaces (753a, 754a) may be greater than those of the distal facing first and second opposed lateral surfaces (753b, 754b) for greater slip-on convenience assembly of the nut 74 to the sleeve 18 and following deformation of the inner surface of the sleeve 18 via the plurality of peaks 751 of the nut 74, greater fixing and grip mounting to the sleeve 18, whereby unmounting and/or rotational slippage due to, as an example, dynamic stresses or screwing and unscrewing of the coaxial cable connector is hindered.

In the embodiments, the material of the nut 14, 24, 34, 74, post 10, 50, fixing washer 30, and annular flange 12 may comprise electrically conductive material such as copper, bismuth, silver, nickel, tin, gold, copper gold-alloy, copper tin-alloy, copper nickel-alloy, or good electrically conductive polymer, or non-metal conductor etc. The surface of the nut 14, 24, 34, 74, post 10, 50, fixing washer 30, and annular flange 12, may be covered with an antirust layer or have an electroless plating process performed thereto. The material of the sleeve 18 may comprise rubber material, or soft polymaterial, or other elastic and waterproof sealing polymaterial etc.

In the embodiments, the shape of each of the plurality of crests is quadrilateral shaped and the dimensions thereof are between 0.51 to 0.57 millimetres (width), inclusive, and 4.88 to 5.48 millimetres (longitudinal length), inclusive. In some embodiments, the width and longitudinal length are 0.54 and 5.18 mm, respectively. Those of ordinary skill in the relevant art may readily appreciate that the dimensions of the plurality of crests may vary dependent upon requirements, so long as the shape and dimensions of the outside of the nut correspond to the shape and dimensions of proximal sleeve interior portion 186a of the sleeve 18 and the nut is configured to be fixedly gripped and mounted thereto, whereby a plurality of deformed indentations is formed on an inner surface of the sleeve 18, such that unmounting and/or rotational slippage due to, as an example, dynamic stresses or screwing and unscrewing of the coaxial cable connector is hindered.

Conventional coaxial cable connectors generally comprise a connector body having a post which is able to house a coaxial cable therethrough, a nut, rotatably coupled to the post, mounting the conventional coaxial cable connector to a rack, casing, apparatus or device having a mounting means built therein, and an annular flange, between the post and nut.

The coaxial cable connectors may further comprise a sleeve, for securing the coaxial cable positioned within the connector body of the conventional coaxial cable connector to the interface port. The sleeve is basically formed of an elastic plastic material and is slidably engaged to the connector body of the coaxial cable connector. However, often the coaxial cable connectors are not properly mounted to the interface port.

The coaxial cable connectors may be over-tightened to the interface port. Thus, proper electrical mating of connector components with the interface port would also not occur. After being over-tightened, electrical mating may be faulty because the connector components are caused to yield and/or move out of proper physical connection with the interface port. This is generally more common for the coaxial cable connectors not having o-rings placed between the post and nut at rotatable portions therebetween, where waterproof sealing may not be required for the coaxial cable connectors being used indoors.

In the embodiments, a coaxial cable connector comprising a sleeve, nut, post, and annular flange is provided. The post is assembled to the nut, the annular flange to the post, and post, annular flange and nut to the sleeve. The nut has a plurality of nut sides, and a plurality of crests between the plurality of nut sides, each having a raised ridged pattern thereon. Each raised ridged pattern comprises a first plurality of grooves having a first groove helix angle and a second plurality of grooves having a second groove helix angle, intersecting the first plurality of grooves, forming a plurality of peaks. Following assembly, a plurality of deformed indentations is formed on an inner surface of the sleeve via the plurality of peaks of the nut.

The embodiments provide a coaxial cable connector, comprising a sleeve, a post, an annular flange, and a nut. The post is assembled to the nut, the annular flange is assembled to the post and nut, and the nut, annular flange and post is assembled to the sleeve. The sleeve is made of elastic material and configured for easy and convenient gripping, whereby the shape and dimensions of the outside of the nut correspond to the shape and dimensions of the inside of the sleeve. Thus, the nut of the coaxial cable connector is easily rotated by the sleeve, by, as an example, a persons' fingers. Also, the elasticity of the sleeve increases torque tightening efficiency, thus, allowing the coaxial cable connector to be fully engaged with and be tightened to interface ports of racks, casings, apparatuses or devices, while mitigating over-tightening thereto. Furthermore, the nut comprises a plurality of crests, and each has a raised ridged pattern thereon, forming pyramids, whereby each pyramid has a peak. A depth, pitch (P), and amount of the peaks, are configured such that the nut is conveniently slip-on assembled to the sleeve, forming a plurality of deformed indentations on an inner surface thereof via the nut. The depth, pitch (P), and amount of plurality of peaks, are configured such that a greater amount of inner surface deformation is achieved, increasing ploughing friction, resulting in a higher friction value. Thus, the nut is fixedly gripped and mounted to the sleeve, such that unmounting and/or rotational slippage due to, as an example, dynamic stresses or screwing and unscrewing of the coaxial cable connector is hindered. Accordingly, proper electrical mating of connector components with interface ports of racks, casings, apparatuses or devices is ensured.
