Description
Patent Application Of Gilbert Langlois and Pierre Langlois, For a TOOL FOR MOUNTING COAXIAL CABLE CONNECTORS ON COAXIAL CABLES
FIELD OF THE INVENTION:
10 The present invention relates to the general field of tools and is particularly concerned with a tool for in~lling coaxial cable connectors on conventional coaxial cables.
BACKGROUND OF THE INVENTION:
15 Coaxial cables are used extensively for carrying signals to a variety of common devices such as televisions, VCRs. cable converters, radio systems and the like. Typical coaxial cables include a centrally located inner electrical conductor surrounded by an outer electrical conductor that is inwardly spaced relative to the inner conductor. A dielectric insulator is positioned between the inner and outer conductors. The outer conductor is protectively surrounded by a dielectric jacket. Conventionally, the 20 inner conductor is made of a conductive wire while the outer conductor fomls a sleeve made of a sheet of fine braided metallic strands, a metallic foil or multiple layer combinations of either or both.
Coaxial cables are typically provided with coaxial cable connectors mounted at each longitudinal end thereof. The connectors are adapted to be threaded into a complimentary interface port so as to 25 electrically integrate the coaxial cables to the various electronic devices. Most conventional coaxial cable connectors have a generally tubular configuration defining a connector front end carrying an appropriate fastener designed to mate with the equipnlent ports or terminals. The conventional cable connectors typically also define a rear end having either a single inner sleeve or inner and outer radially spaced open-ended concentric sleeves. When two concentric sleeves are used, the inner sleeve is configured so as to be insertable into the specific section of the coaxial cable in electrical contact with the outer conductor and electrically insulated from the inner conductor by means of a dielectric insulator. The S outer sleeve is gripped to securely couple the connector to the cable and to achieve an electrical ground connection and weather seal.
Although conventional coaxial cables and conventional coaxial cable connectors adequately perform their respective functions, they collectively suffer from at least one major drawback. Indeed, although well 10 designed for their individual intended purpose, they are relative difficult to assemble.
Mounting a conventional cable connector to a conventional coaxial cable involves a set of unergonomic steps. In order to integrate a coaxial cable connector with a coaxial cable, an individual must first strip away a pre~letermined length of outer conductor and dielectric insulators to leave only a pre~letermined 15 length of inner conductor protruding from the end section of the coaxial cable. The individual must then secure with one hand the end section of the coaxial cable and use the other hand to force the inner sleeve of the connector into the cable end with the sleeve mechanically engaging the outer conductor.
When an outer sleeve is used, a crimp tool is used to crimp the outer sleeve on the outer surface of the protective jacket. This operation not only requires manual dexterity but is also tedious and time 20 ~;O~ IIIillg Furthermore, the relatively small cablc connector is difficult and awkward to manipulate thus potentially leading to illlplUpel engagement of the connector with the conductive components of the cûaxial cable. Furthennûre, the relatively sharp edges of the connector and/or pointed tip of the conductors may puncture the skin of the installer thus potentially causing injury.
25 Grasping of both the connector and the cable reduces the accuracy of the mounting operation, which requires a certain degree of precision for providing optimal contact between the connector and the coaxial cable. Also, the length of the stripped portion of the inner conductor must be gauged accurately so that a predetermined length of inner conductor protrudes from the connector once the latter is mounted on the cable.
Accordingly, there exists a need for a tool facilitating the mounting of coaxial cable connectors on 5 conventional coaxial cables. Advantages of the present invention include the fact that the proposed tool allows for easy and ergonomic mounting of a conventional coaxial cable connector on the end section of a conventional coaxial cable. The proposed tool reduces the risk of (l~m~gine both the connector and the cable. Also, the proposed tool increases the accuracy of the connection and thus improved the electrical properties of the assembled cable-connector combination.
Furthermore, the proposed tool reduces the amount of time required for mounting the connector to the cable and the amount of manual dexterity required for pe-roll..hlg the operation. Also, the proposed tool reduces the risk of injury related to the assembly operation and ensures relatively constant achievement of a proper contact that will withstand frequent use and connect-disconnect cycles.
Still further, the proposed tool is specifically designed so as to be m~nllf:~ctllrable using conventional methods of manufacturing so as to provide a tool that will be economically feasible, long lasting and relatively trouble free in operation.

15 DETAILED DESCRIPTION OF THE DRAWINGS:
Referring to Figure 2, there is shown in a partial elevational view with sections taken out, a tool 10 in accordance with an embodiment of the present invention, a conventional cable connector 12 and an end section part of a conventional coaxial cable 14.
In the example herein selected for illustrative purposes, the cable 14 includes an inner conductor 16 surrounded by and spaced inwardly from an outer conductor 18. Typically, the inner conductor 16 takes the form of an electrically conductive wire while the outer conductor 18 takes the form of a cylindrical sleeve made of a sheet of fine braided metallic strands, metallic foil or multiple layer coll-l)inalions of 25 either or both.
The inner and outer conductors 16 and 18 are electrically isolated one from the other by an inner in~nl~ting sleeves 20 interposed the~ ween. The inner incnl~ting sleeves 20 is made out of a conventional dielectric in~ul~ting material. The outer conductor 20 is protectively surrounded by an outer incnl~ting sleeve 22 typically made out of an ~ tomrric material.
In the example herein selected for illustrative purposes, the cable connector 12 has a generally elong;lted connector stem 24 defining a stem distal end 26 and a longitudinally opposed stem proximal end 28. A
stem flange 30 extends from the stem 24 adjacent the stem proximal end 28. The stem 24 has a stem channel 32 ~.xten-ling longitll-lin~lly therethrough. The stem channel 32 is preferably configured and 10 sized for fittingly receiving the inner conductor 16. The stem 24 is preferably provided with serrations 34 formed on its outer surface adjacent the stem distal end 26 for frictionally ~.n~ging inner components part of the coaxial cable 14.
A connector fastening sleeve 36 is rotatably mounted on the stem flange 30. Typically, the stem flange 30 15 defines a sleeve retaining groove 38 for receiving an inwardly bent distal segment of the connector f~ctening sleeve 36. The inwardly bent segment is arranged to coact in mechanical inter engagement with the groove 38. The connector fastening sleeve defines a connector sleeve proximal peripheral edge 40. The connector fastening sleeve has an internal thread 42. Preferably the connector fastening sleeve is further provided with a radially outwardly extending segmented prohlberance 44 for facilitating grasping 20 with conventional tools such as pliers or the like.
Other conventional connector construction (not shown) typically include an outer radially spaced conce.lllic sleeve provided with internal serrations for mounting over the outer in~ul~ting sleeve 22 of the cable 14.
It should be understood that both the cable connector 12 and the coaxial cable 14 are only shown as examples of cables and connectors that can be assembled together using the tool 10 in accordance with the present invention and that other cable and connector configurations could be used without departing from the scope of the present invelltion.
The tool 10 includes a handle 46 and a tool f,lctening sleeve 48 attached to the handle 46. The tool s f~ctPning sleeve 48 has a tool f~ctening sleeve external thread 50 formed thereon. The tool fastening sleeve is configured and sized so that its external thread 50 may threadaly engage the internal sleeve thread 42 of the cable connector 12. The tool f~c~e~ lg sleeve 48 also has a tool fastening sleeve channel 52 for receiving a segment of the inner conductor 16 extending through the connector sleeve 36 and protruding from the connector sleeve proximal peripheral edge 40.
Preferably, the handle 46 has a sllhst~nti~lly "T" shaped general configuration defining a spacing segment 54 generally coaxial with the tool fastening sleeve channel 52 and a substantially perpendicular grasping segment 56. The grasping segment 56 preferably defines a contoured section 58 provided with grooves 60 configured and sized for receiving the fingers of an intended use so as to facilitate grasping of the 15 grasping section 56. The section 58 thus adapted to act as a finger Pngaging section while an opposed rectilin~.~r section 62 is adapted to act as a palm contacting section 62 when the grasping section 56 is grasped by the hand of an intended user.
The spacing segment 54 defines a spacing segment proximal end 64 and a longitll-lin~lly opposed spacing 20 segment distal end 66. The tool fastening sleeve 48 is preferably attached to the spacing segment distal end 66. A sleeve receiving recess 68 is formed in the spacing segment distal end 66. The sleeve receiving recess 68 is provided with an internal thread configured and sized for receiving a proximal segment of the tool f~ctening sleeve 48. A conventional washer type component 70 is used for limiting insertion of the proximal segment of the tool f~ctening sleeve 48 within the sleeve receiving recess 68.
Preferably, the tool 10 is provided with a stripping means moullted thereon for stripping away a section of the outer conductor 18, the inner incllla~ing sleeve 20 and the outer in.c~ ting sleeve 22 so as to define an inner conductor lln~cce-nhled protruding segment 72. Typically, the stripping means includes a stripping aperture 74 formed in the handle 46 and preferably in the grasping section 56 thereof. At least one stripping blade 76 is mounted so as to extend at least partially through the stripping aperture 74.
Preferably, the stripping aperture 74 has a blade mounting edge 78 and an opposed cable abutment edge section 80. A cable abutment edge section 80 is provided with grooves formed thereon.
The tool 10 preferably further including a gauging means for gauging the length of the inner conductor lln~cc~."hled protruding segment 72. The gauging means preferably includes a gauging aperture extending through the handle 46 typically through the spacing segment 54 thereof. As illustrated more 10 specifically in Figure 5, the gauging aperture define a complete cable receiving section configured and sized for receiving a distal section of the cable 14 with its inner and outer conductor 16. 18 and both its inner and outer inc~ ing sleeves 20? 22. The gauging aperture also defines an inner conductor receiving section configured and sized for receiving the inner conductor unassellll)led protruding section 72. The complete cable receiving section 84 and the inner conductor receiving section 86 part of the 15 gauging aperture 82 define an abu~lllell~ shoulder 88.
The tool 10 preferably further includes a hooking aperture 86 extending through the handle 46 preferably adjacent a longitudinal end of the grasping section 46. A hooking aperture 86 is configured and sized for receiving a conventional hooking component extending from a supporting wall (not shown).
In use, in order to mount the connector 12 to an end section of the cable 14, a distal segment of the outer conductor 18 and both the inner and outer insulating sleeves 20, 22 are first stripped away from a distal segment of the inner connector 16 so as to form the inner connector nn~c5enlhled protruding segment 72.
In order to perform the stripping operation, an intended use merely needs lo insert a predetermined length 25 of the cable 14 in the stripping apenure 74 abuttingly contacting the cable abuhnent segment 80 and the blade 76 so as to strip the proper segment using a pulling and rotating movement as is well known in the art. The angled configuration of the blade 76 and the serrations fomled in the cable abuhnent section 80 allow for stripping of cables h<lvillg various diameters.
The length of the inner conductor lin~ d protruding segment 72 must be substantially accurately obtained according to predetermined requirements so that the inner conductor assembled protruding segment 88 presents a suitable length. The length of segment 88 must be m~int~inPd within a predl~te-min~d range in order to ensure proper electrical contact with the terminals of the components to which the cable 14 is to be attached.
10 In order to ensure precise stripping so as to obtain relatively precise length of the segment 72 tlle built in gauging means may be used. The strip portion of the cable 14 is inserted within the gauging aperture 82 until an abutment edge 92 of the stripped cable abuttingly contacts the shoulder 90. The length of the inner conductor receiving section 86 is customized typically at values cl1kct~nti:l11y in the range of 1/2" so as to provide section 72 having a predetermined length.
In order to install the connector 12 on the distal end of the cable 14, the connector 12 is first releasably mounted on the tool 10 by threadaly en~ging the internal sleeve thread 42 of the connector f~.ctPning sleeve 36 over the tool f~ctening sleeve external thread 50. With the connector 12 mounted on the tool f~c1ening sleeve 48 the inner conductor nn~ccrlllhled protruding segment 72 is aligned with the stem 20 chalmel 32 and the tool 10 is used to push the stem 24 into the distal end of the cable 14 using a pushing and rotating motion as shown by arrows 94 and 96 of Figure 3.
As the stem 24 penetrates in the cable 14 the tool fa.ctening sleeve channel 52 receives the segment of the inner conductor 16 protruding in the connector fastening sleeves 36 and protruding from the connector 25 f~ctening sleeves proximal peripheral edge 40. Once the stem is properly inserted within the cable 14 the serration 34 frictionally prevents retraction therefrom wllile the tool 10 is rotated so as to disengage the tool f~c~ning sleeve external threads 50 from the connector f~ctening sleeve internal sleeve threads 42.
When not in use, the tool 10 may be stored itl a convelliellt manner by hooking the prehension section 52 5 to a supporting wall using a conventional hooking structure sucll as a hook or a nail inserted through the hooking aperture 86.

The tool 10 includes a handle 46 and a tool f,lctening sleeve 48 attached to the handle 46. The tool s f~ctPning sleeve 48 has a tool f~ctening sleeve external thread 50 formed thereon. The tool fastening sleeve is configured and sized so that its external thread 50 may threadaly engage the internal sleeve thread 42 of the cable connector 12. The tool f~c~e~ lg sleeve 48 also has a tool fastening sleeve channel 52 for receiving a segment of the inner conductor 16 extending through the connector sleeve 36 and protruding from the connector sleeve proximal peripheral edge 40.
Preferably, the handle 46 has a sllhst~nti~lly "T" shaped general configuration defining a spacing segment 54 generally coaxial with the tool fastening sleeve channel 52 and a substantially perpendicular grasping segment 56. The grasping segment 56 preferably defines a contoured section 58 provided with grooves 60 configured and sized for receiving the fingers of an intended use so as to facilitate grasping of the 15 grasping section 56. The section 58 thus adapted to act as a finger Pngaging section while an opposed rectilin~.~r section 62 is adapted to act as a palm contacting section 62 when the grasping section 56 is grasped by the hand of an intended user.
The spacing segment 54 defines a spacing segment proximal end 64 and a longitll-lin~lly opposed spacing 20 segment distal end 66. The tool fastening sleeve 48 is preferably attached to the spacing segment distal end 66. A sleeve receiving recess 68 is formed in the spacing segment distal end 66. The sleeve receiving recess 68 is provided with an internal thread configured and sized for receiving a proximal segment of the tool f~ctening sleeve 48. A conventional washer type component 70 is used for limiting insertion of the proximal segment of the tool f~ctening sleeve 48 within the sleeve receiving recess 68.
Preferably, the tool 10 is provided with a stripping means moullted thereon for stripping away a section of the outer conductor 18, the inner incllla~ing sleeve 20 and the outer in.c~ ting sleeve 22 so as to define an inner conductor lln~cce-nhled protruding segment 72. Typically, the stripping means includes a stripping aperture 74 formed in the handle 46 and preferably in the grasping section 56 thereof. At least one stripping blade 76 is mounted so as to extend at least partially through the stripping aperture 74.
Preferably, the stripping aperture 74 has a blade mounting edge 78 and an opposed cable abutment edge section 80. A cable abutment edge section 80 is provided with grooves formed thereon.
The tool 10 preferably further including a gauging means for gauging the length of the inner conductor lln~cc~."hled protruding segment 72. The gauging means preferably includes a gauging aperture extending through the handle 46 typically through the spacing segment 54 thereof. As illustrated more 10 specifically in Figure 5, the gauging aperture define a complete cable receiving section configured and sized for receiving a distal section of the cable 14 with its inner and outer conductor 16. 18 and both its inner and outer inc~ ing sleeves 20? 22. The gauging aperture also defines an inner conductor receiving section configured and sized for receiving the inner conductor unassellll)led protruding section 72. The complete cable receiving section 84 and the inner conductor receiving section 86 part of the 15 gauging aperture 82 define an abu~lllell~ shoulder 88.
The tool 10 preferably further includes a hooking aperture 86 extending through the handle 46 preferably adjacent a longitudinal end of the grasping section 46. A hooking aperture 86 is configured and sized for receiving a conventional hooking component extending from a supporting wall (not shown).
In use, in order to mount the connector 12 to an end section of the cable 14, a distal segment of the outer conductor 18 and both the inner and outer insulating sleeves 20, 22 are first stripped away from a distal segment of the inner connector 16 so as to form the inner connector nn~c5enlhled protruding segment 72.
In order to perform the stripping operation, an intended use merely needs lo insert a predetermined length 25 of the cable 14 in the stripping apenure 74 abuttingly contacting the cable abuhnent segment 80 and the blade 76 so as to strip the proper segment using a pulling and rotating movement as is well known in the art. The angled configuration of the blade 76 and the serrations fomled in the cable abuhnent section 80 allow for stripping of cables h<lvillg various diameters.
The length of the inner conductor lin~ d protruding segment 72 must be substantially accurately obtained according to predetermined requirements so that the inner conductor assembled protruding segment 88 presents a suitable length. The length of segment 88 must be m~int~inPd within a predl~te-min~d range in order to ensure proper electrical contact with the terminals of the components to which the cable 14 is to be attached.
10 In order to ensure precise stripping so as to obtain relatively precise length of the segment 72 tlle built in gauging means may be used. The strip portion of the cable 14 is inserted within the gauging aperture 82 until an abutment edge 92 of the stripped cable abuttingly contacts the shoulder 90. The length of the inner conductor receiving section 86 is customized typically at values cl1kct~nti:l11y in the range of 1/2" so as to provide section 72 having a predetermined length.
In order to install the connector 12 on the distal end of the cable 14, the connector 12 is first releasably mounted on the tool 10 by threadaly en~ging the internal sleeve thread 42 of the connector f~.ctPning sleeve 36 over the tool f~ctening sleeve external thread 50. With the connector 12 mounted on the tool f~c1ening sleeve 48 the inner conductor nn~ccrlllhled protruding segment 72 is aligned with the stem 20 chalmel 32 and the tool 10 is used to push the stem 24 into the distal end of the cable 14 using a pushing and rotating motion as shown by arrows 94 and 96 of Figure 3.
As the stem 24 penetrates in the cable 14 the tool fa.ctening sleeve channel 52 receives the segment of the inner conductor 16 protruding in the connector fastening sleeves 36 and protruding from the connector 25 f~ctening sleeves proximal peripheral edge 40. Once the stem is properly inserted within the cable 14 the serration 34 frictionally prevents retraction therefrom wllile the tool 10 is rotated so as to disengage the tool f~c~ning sleeve external threads 50 from the connector f~ctening sleeve internal sleeve threads 42.
When not in use, the tool 10 may be stored itl a convelliellt manner by hooking the prehension section 52 5 to a supporting wall using a conventional hooking structure sucll as a hook or a nail inserted through the hooking aperture 86.
