Abstract

A coaxial cable connector system, comprising a coaxial connector, a coaxial cable, and a universal coaxial cable fixing sleeve is provided. The universal coaxial cable fixing sleeve comprises a first gripping component, a second gripping component, and a third gripping component. When the coaxial cable is assembled to the universal coaxial cable fixing sleeve, the first gripping component grips a conductive shield of the cable, and the second and third gripping components grip a protective outer jacket of the cable, respectively. When the universal coaxial cable fixing sleeve is engaged to a first connector, a first housing outer surface thereof corresponds to and fixedly engages with a sleeve receiving inner surface of the first connector, and when disengaged and engaged to a second connector different in type from the first connector, no re-preparation of the cable is required for corresponding fixed engagement.

First claim

What is claimed is:

1. A coaxial cable connector system, comprising:
a coaxial connector comprising a nut, defining an interior channel therethrough, comprising a mating end portion configured to couple with a mating connector and a fixing sleeve receiving portion including a distal fixing sleeve receiving end and a fixing sleeve receiving inner surface having a fixing sleeve receiving stop wall;
a coaxial cable having a center conductor, surrounded by a dielectric core, which is covered by at least a conductive shield and a protective outer jacket; and
a universal coaxial cable fixing sleeve comprising:
a housing, defining an interior channel therethrough, comprising a first housing portion including a first housing inner surface, a second housing portion having a second housing outer surface and a second housing stop wall between the first housing portion and second housing outer surface, and a housing distal end;
a receiving sleeve, defining an interior channel therethrough, including a proximal sleeve end, a first sleeve portion having a first sleeve inner surface, a central sleeve inner surface, and a central sleeve stop wall, and a second sleeve portion having a second sleeve inner surface and a second sleeve ledge at a distal end thereof, wherein the central sleeve stop wall is between the proximal sleeve end and second sleeve ledge, whereby when assembled, the proximal sleeve end and first sleeve inner surface rests flush against the second housing stop wall and the second housing outer surface, respectively;
a first gripping component fixedly attached to the first housing inner surface;
a second gripping component having one end fixedly attached to the housing distal end;
a deflecting ring having a ring inner ramp positioned flush against the second gripping component, a ring outer surface fixedly attached to the central sleeve inner surface, and a ring distal inner groove opposite the ring inner ramp; and
a third gripping component fixedly attached within the ring distal inner groove, second sleeve inner surface, and second sleeve ledge,

whereby when the coaxial cable is assembled to the universal coaxial cable fixing sleeve, the first gripping component grips a conductive shield of the cable, and the second and third gripping components grip the protective outer jacket of the cable, respectively, whereby the individual gripping of the conductive shield and protective outer jacket are each, positioned in at least three concentric and evenly separated positions, and whereby when the universal coaxial cable fixing sleeve is assembled to the coaxial connector, the first housing portion is fixedly engaged to the fixing sleeve receiving portion.

2. The universal coaxial cable fixing sleeve of claim 1 , wherein the first housing portion further comprises a first housing outer surface, opposite to and encompassing the first housing inner surface, whereby when the universal coaxial cable fixing sleeve is engaged to a first connector of the coaxial cable connector system, a fixing sleeve receiving inner surface of a fixing sleeve receiving portion of the first connector correspond to and engage with the first housing outer surface, and no re-preparation of the cable is required, and whereby when the universal coaxial cable fixing sleeve is engaged to a second connector of an alternative coaxial cable connector system, a fixing sleeve receiving inner surface of a fixing sleeve receiving portion of the second connector correspond to and engage with the first housing outer surface, and no re-preparation of the cable is required.

3. The universal coaxial cable fixing sleeve of claim 1 , wherein the first gripping component comprises a first proximal base, a first distal base, and a plurality of elastic arches, each having crowns, whereby an end of each of the plurality of elastic arches is integrally formed with the first proximal base and an opposite end of each of the plurality of elastic arches is integrally formed with the first distal base, whereby each of the crowns of the plurality of elastic arches is positioned toward a center of the interior channel, and whereby when a cable of the coaxial cable connector system is assembled therethrough, each of the crowns of the plurality of elastic arches is deformed to grip the conductive shield of the cable.

4. The universal coaxial cable fixing sleeve of claim 1 , wherein the second gripping component comprises a second distal base and a plurality of elastic fingers, each plurality of elastic fingers having a finger gripping end and a finger base end, wherein a diameter of the finger gripping end is less than a diameter of the finger base end, whereby the finger base end is integrally formed with the second distal base and the second distal base is fixedly attached to the housing distal end, whereby the ring inner ramp of the deflecting ring is positioned flush against the plurality of elastic fingers, facilitating radially inward positioning at an angle of inward incline, and whereby when a cable of the coaxial cable connector system is assembled therethrough, each of the finger gripping ends of the plurality of elastic fingers are moved radially inward to grip the protective outer jacket of the cable, hindering removal of the cable.

5. The universal coaxial cable fixing sleeve of claim 1 , wherein the third gripping component comprises a third gripping proximal end, a third gripping distal end opposite the third griping proximal end, an inner flat compression portion, an inner flat portion, an inner elastic slope between the inner flat compression and inner flat portions, and a third gripping outer surface opposite to and encompassing the inner flat compression portion, inner flat portion and inner elastic slope, whereby a portion of the third gripping proximal end and third gripping outer surface is fixedly attached within the ring distal inner groove and a portion of the third gripping distal end and third gripping outer surface is fixedly attached to the second sleeve inner surface, and second sleeve ledge, whereby when a cable of the coaxial cable connector system is assembled therethrough, the inner flat compression portion is deformed and compressed to grip the protective outer jacket of the cable, hindering removal of the cable and creating a weatherproof seal around the cable.

6. The universal coaxial cable fixing sleeve of claim 2 , wherein the first and second connectors comprise BNC, TNC, SMA, N-Type, F-Type, and MCX and RCA connector types and are not the same, whereby the first housing outer surface is configured to engage within the fixing sleeve receiving inner surface of the BNC, TNC, SMA, N-Type, F-Type, and MCX and RCA connector types.

7. The universal coaxial cable fixing sleeve of claim 5 , wherein an angle of inward incline of the inner elastic slope is between 20° degrees to 35° degrees, facilitating deformation and compression of the inner flat compression portion to grip the protective outer jacket of the cable.

8. A coaxial cable connector system, comprising:
a coaxial cable connector comprising:
a nut, defining an interior channel therethrough, comprising a mating end portion configured to couple with a mating connector, a slidable distal end, and a rotating portion including a first nut inner surface having a nut sliding wall between the slidable distal end and first nut inner surface and a second nut inner surface;
a coaxial cable fixing sleeve comprising:
a main housing, defining an interior channel therethrough, comprising, a main housing proximal portion having a main housing proximal end and a main housing proximal inner surface, and a main housing distal portion having a main housing distal end opposite the main housing proximal end and a main housing outer surface having a main housi
