The present application claims priority to Taiwan application no. 106214271, filed on Sep. 26, 2017, of which is hereby incorporated by reference in its entirety.


Field of the Invention

The invention relates to compression tools, and more particularly, to adjustable coaxial cable compression tools.


DESCRIPTION OF THE RELATED ART

Coaxial cables connectors, for example, F-type connectors for RG-6 and RG-6 Quad cables and BNC connectors, are used for CATV, satellite and video applications etc. Generally, twist-on coaxial cable connectors are convenient, but, can be dislodged easily, while compressed coaxial cable connectors are durable. A compression tool can be used to install a coaxial cable connector onto the end of a coaxial cable. However, depending upon the compression tool used, versatility may be non-existent or limited, when compressing coaxial cable connectors of different types, sizes, diameters and lengths. For compression tools with limited versatility and/or a larger size and/or multiple parts and/or multi-step adjustments, operation thereof can be a hindrance. Additionally, versatility, functionability, easability and durability of use are challenges.


There is demand for adjustable coaxial cable compression tools to solve the aforementioned problem.

As shown in FIG. 3a and FIG. 3b, in an embodiment, a coaxial cable 40 and coaxial cable connector 38 is coaxially aligned within the main body guideway 1124, fixed guideway 28a, first guideway 302, second guideway 322, and first and second die cavities 2649, 2628. The coaxial cable 40, as an example, and not to be limiting, comprises an external jacket 9, thin conductive shield 5, braided textile wrap 7, dielectric insulator 3, and a center conductor 1. The coaxial cable connector 38, as an example, and not to be limiting, comprises a drive head nut 386, an outer sleeve 384 and an inner sleeve 382, wherein the drive head nut 386 is sleeved on the inner sleeve 382 and the outer sleeve 384 is coaxially disposed on the inner sleeve 382, and the outer sleeve 384 and inner sleeve 382 form an outer-inner sleeve gap 387 at a cable connecting end thereof. The outer sleeve 384 has a diameter d1.


In an embodiment, an appropriate sized, shaped and type plunger head end 244, corresponding to the coaxial cable connector 38, is assembled to the plunger 16, wherein the plunger head end 244 is coaxially aligned with the fixed coaxial cable 40 and coaxial cable connector 38, between the plunger 16 and the coaxial cable connector 38. Additionally, an appropriate sized, shaped and type guideway plate is rotatably fit flush with the die support recess 110 and a die fixing screw 119, fixes the body 10 to the second die half 262 of the die block 26 via the die fixing through hole 110a and die fixing screw hole 2629a.


To begin, an end portion of the braided textile wrap 7 is wrapped back over the external jacket 9, to allow the thin conductive shield 5, dielectric insulator 3, and a center conductor 1 to enter the coaxial cable connector 38, wherein the center conductor 1 coaxially protrudes through to the drive head nut 386. Next, the assembled coaxial cable 40 and coaxial cable connector 38 is coaxially aligned and positioned within the main body guideway 1124, appropriate guideway, and second die cavity 2628. Following, the plunger head connector 22 of the plunger 16 is axially advanced to the drive head nut 386 of the coaxial cable connector 38, wherein the center conductor 1 coaxially protrudes through to the center of the plunger head end 244 as the top surface of the plunger head end 244 abuts an end of the thin conductive shield 5 and dielectric insulator 3. After, the first die half 264 is rotated toward the second die half 262, and the die lever 266 attached to the first die half 264 is snap hooked onto the second die pin 268 of the second die half 262 to secure the assembled coaxial cable 40 in the die block 26. The diameter of a compression end of the first and second die cavities 2649, 2628 is smaller than the diameter of a non-compression end of the first and second die cavities 2649, 2628. The compression end is the end closest to the main body guideway support 112. The first and second die cavities 2649, 2628 comprise a tapered slope 261. Next, the lever arm 12 is rotated toward the body 10, whereby the floating link 14 rotatably attached to the arm offset 122 and plunger 16 is advanced forward toward the main body guideway support 112 via the spring 165, plunger 16, plunger head connector 22 and plunger head 24. The plunger 61 is axially advanced to force the coaxial cable connector 38 onto the coaxial cable end, radially contracting the coaxial cable connector 38 into compression engagement with the coaxial cable end. Specifically, the plunger head 24 pushes the coaxial cable connector 38 against the inner wall of the tapered siding 261 of the first and second die cavities 2649, 2628. During advancement, the cavity grip grooves 2623 hinder the outer sleeve 384 of the coaxial cable 40 to move further into the compressed areas. The compressed spring 165 exerts spring force between the sleeve end flange 1672 of the plunger sleeve end 167 and front sidewall of the bifurcated plunger end 162 of the plunger 16. Accordingly, the outer-inner sleeve gap 387 compresses along with the outer sleeve 384 and the braided textile wrap 7 and the external jacket 9 of the coaxial cable 40 are pressed together. The outer sleeve 384 is compressed from diameter d1 to diameter d2, adjacent to the outer sleeve 384 near the drive head nut 386. The coaxial cable 40 is tightly coupled with the coaxial cable connector 38 and is durable. Next, the lever arm 12 is retracted, allowing the spring force of the spring 165 to move the plunger head 244 and plunger 16 back toward the level arm 12. Lastly, the die lever 266 attached to the first die half 264 is unhooked from the second die pin 268 of the second die half 262, and the first die half 264 is rotated away from the second die half 262 to remove the compressed coaxial cable connector.


In the embodiments, as an example, and not to be limiting, the body 10, lever arm 12, floating link 14, plunger 16, spring 165, plunger pin 167, plunger head connector 22, plunger head 24, die block 26, fixed guideway plate 28, first moveable guideway plate 30, second moveable guideway plate 32, and alternative moveable guideway plates 34, can be made of copper, bismuth, silver, nickel, tin, gold-copper alloy, copper-tin alloy, copper-nickel alloy brass, brass alloy, phosphorous bronze, beryllium-copper, aluminum, aluminum alloy, zinc alloy, steel-bismuth alloy or any combination thereof or combination of other high strength polymer plastics.


Coaxial cables connectors, for example, F-type connectors for RG-6 and RG-6 Quad cables and BNC connectors, are used for CATV, satellite and video applications etc. Generally, twist-on coaxial cable connectors are convenient, but, can be dislodged easily, while compressed coaxial cable connectors are durable. A compression tool can be used to install a coaxial cable connector onto the end of a coaxial cable. However, depending upon the compression tool used, versatility may be non-existent or limited, when compressing coaxial cable connectors of different types, sizes, diameters and lengths. For compression tools with limited versatility and/or a larger size and/or multiple parts and/or multi-step adjustments, operation thereof can be a hindrance. Additionally, versatility, functionability, easability and durability of use is a challenge.


The adjustable coaxial cable compression tool of the embodiments, terminating a coaxial cable connector onto a coaxial cable end, comprising a plunger, a body, a fixed guideway plate, a first moveable guideway plate, a second moveable guideway plate, and a die block, is versatile, functional, easy to use and durable. The plunger comprises a first plunger head and a second plunger head, both having different shapes conforming to different types of coaxial cable connectors and are interchangeable. The body has a body receiving end, wherein the plunger is slidable therein. The fixed, first moveable and second moveable guideway plates have fixed, first and second guideways, each having different diameters, respectively. The die block comprises first and second die halves. The plunger is axially advanced to force the coaxial cable connector onto the coaxial cable end, radially contracting the coaxial cable connector into compression engagement with the coaxial cable end. The adjustable coaxial cable compression tool of the embodiments, via the interchangeable plunger heads, die block, and different sized guideway plates, can be used with coaxial cable connectors of different types, sizes, diameters and lengths, such as F-type BNC, RCA, XLR, DFP, DVI, SCART and RF cable connectors etc. for versatility, functionability, easability and durability.
