The present invention relates to a coaxial cable connector, and more particularly, to a reliable connection without adding unnecessary cost and complexity between the braided coaxial cable and the trunk equipment ports or without adversely affecting the performance of the network. It provides a coaxial cable connector provided.

Coaxial cable is a typical transmission medium used in modern communication networks such as CATV networks. Most of these networks are generally formed from standard "hard-line" coaxial cables, which include hard or semi-rigid outer connectors and are typically covered with weather protection jackets. This design effectively prevents radiation leakage and signal loss, while providing excellent physical protection (eg shielding) for the inner conductors and dielectrics of sensitive cables. Therefore, standard hard line coaxial cables are commonly used, extending to a minimum straight line along the transmission portion of the network, which is more difficult to diagnose leaks and signal losses and this negative impact can have a greater impact on the entire communication network.

However, standard hard coaxial cables are significantly more expensive and more difficult to install than braided coaxial cables with large gauges such as RG11 type cables. Such cables typically include a center conductor surrounded by a dielectric core wrapped in one or more layers of metal foil surrounded by metal braided wire or wire mesh outer conductor and wrapped by an outer protective jacket. Such braided coaxial cable does not provide the level of physical protection that standard coaxial coaxial cable can provide, but is structurally relatively flexible. Therefore, in spite of the problem of physical protection, which is relatively weak compared to the standard hard wire coaxial cable, when the braided coaxial cable is used in the communication network, the advantage due to the relatively low cost and flexibility can be obtained.

Because of this advantage, many telecommunications and cable companies have already deployed flexible and inexpensive braided coaxial cable extensively, or at least in the actual areas (such as residential or business areas) where communication network signals are carried. It is used or is intended to be used around a physical obstacle.

In order to maintain the electrical integrity of communication network signals, it is essential that when a braided coaxial cable is used it is firmly interconnected with the ports of the trunk apparatus which distributes or regulates the signals without breaking the cable's ground connection. However, the ports of most trunk devices have mostly "KS" type connections / interfaces, while "KS" type connections / interfaces are designed to be compatible with standard hardwired cables and devices, but flexible coaxial cables are generally It may be difficult to make such an interconnect because it has a braided external connector that uses a "F" type of connection / interface that is incompatible with "KS" type ports.

One solution to this problem is to use an adapter that connects the incompatible "KS" and "F". However, in this case, the nominal assembly costs increase, the skill of the skilled technician is required, and even the adapter is installed correctly, which degrades the performance of the entire communication network. Another method is to use coaxial cable connectors that are specially designed, such as screwed, crimped, or compressed rigid coaxial cable connectors. However, using these connectors with braided coaxial cables is not ideal for a number of reasons, including incompatibilities, installation difficulties, and negative effects on performance.

Thus, it is possible to provide an effective connection between the braided coaxial cable and the trunk line port without using an adapter, without incurring unnecessary costs, without adversely affecting system performance or unnecessarily complicating the installation process. A device is needed.

These and still other needs are met by a device (eg, such as a connector) that interconnects the coaxial cable of the communication network provided by the present invention to a trunk device port. In a non-limiting manner, for example, the coaxial cable can be a RG11 or larger gauge braided coaxial cable. In another example, but not limited to, the communication network may be a computer, cable, or CATV network or similar telecommunication network. And in other ways, but not limited to this, for example, the trunk device to which the cable is connected is a tap, an amplifier, a filter, a trap or the like, and the device port has a particular port interface, such as a port interface of type "KS". .

According to one or more exemplary embodiments of the present invention, the device is configured such that segments of braided coaxial cable are interconnected to the device port. At its end, the connector includes a connector body forming an inner hole and having a first end and a second end, the first end of the connector body having a port interface (such as a port interface of type “KS”) and the connector The second end of the body includes one or more outer ridges to engage the compression mechanism and the inner grooves. Optionally, the inner hole of the body may have a variable diameter between the first and second ends of the connector body in a stepped or tapered manner.

According to one or more exemplary embodiments of the present invention, the apparatus further comprises a post having a first end and a second end. The first end of the post is sized to be able to engage in a portion of the inner hole of the connector body. The second end of the post includes a sleeve configured to engage at least the braided outer conductor of the coaxial cable. Typically, the sleeve is inserted between the dielectric core and the braided outer conductor. However, other configurations are also known in the art where the second end of the post abuts the metal foil layers, or the braided outer conductor that is folded over the outer protective jacket of the coaxial cable. The sleeve may include one or more toothed, barb or tapered portions to assist in the engagement of the braided outer conductor.

According to one or more exemplary embodiments of the present invention, the apparatus further comprises a compression member having a first end, a second end, an inner surface, and an outer surface. The first end of the compression member may include a protruding rib sized to engage over an inner groove of the second end of the connector body such that the compression member is held in the first position, the second end of the compression member and the connector body Can accept the end of the coaxial cable. Alternatively, the first end of the compression member may be sized to press fit into the second end of the connector body. Typically the second end of the compression member comprises a flange configured to engage a compression mechanism (not shown) that slides the compression member into the connector body and further advances in the axial direction. The force of the compression mechanism is sufficient to shear or deform the protruding ribs to allow the compression member to proceed further axially from the groove into the connector body. The flange may also have a diameter that is larger than the diameter of the inner hole of the second end of the connector body to adjust or limit the degree of axial progression into the connector body.

The inner surface of the compression member includes a portion tapering inwardly from the first end to the second end. As the compression member runs in the axial direction, the outer layers of the coaxial cable are compressed and held between the sleeve of the post and the inner surface of the compression member.

The outer surface of the compression member may comprise an annular groove in the middle between the flange of the second end of the compression member and the outer rib of the first end. The outer surface may also include a shoulder between the annular groove and the flange, wherein the shoulder is press-fitted such that the inner diameter of the second end of the connector body is sufficient to hold the connector body in the second position where the compression member is fully axially advanced. It is made to size. The annular groove may have sidewalls that are inclined, at right angles, or have a radius. The annular groove causes the compression member to bend or bend slightly to relieve the compressive stress caused as the compression member progresses in the axial direction, and the foil layers of the coaxial cable supplied by the various manufacturers, braided lines It allows adaptation to variations in the thickness of the outer conductor, outer protective jacket.

Still according to one or more preferred embodiments of the present invention, the device may further comprise or comprise one or more elements. Such elements may include (a) sealing elements such as O-rings disposed about the connector body adjacent the port interface; (b) a lid element associated with the second end of the compression member; (c) a contact pin having a first end adapted to engage a port of a portion of the trunk apparatus, a second end electrically engaged with the center conductor of the coaxial cable, and an intermediate portion; (d) if desired, a collet at the second end of the contact pin, which may include a plurality of tines for receiving and retaining the center conductor of the braided coaxial cable, and (e) disposed in the hollow of the connector body And one or more insulators that electrically insulate the center contact pin and / or collet from the connector body.

A continuous hollow 88 is formed between the first end and the second end of the compression member 80. In an exemplary embodiment of the invention, the compression member is generally a trademark Delrin

It is formed of a deformable plastic material such as acetyl resin. The first end 82 of the compression member may include a protruding rib 100. Rib 100 is provided with an internal groove 102 inside the second end 14 of connector body 12 to hold compression subhead 80 in an assembled but uncompressed first position as shown in FIG. 1. It is shaped to mate or slide. In the first position, the end of the suitably provided coaxial cable (see FIG. 3) passes through the opening 19 of the second end 14 of the connector body 12 through the opening 104 of the second end 84 of the compression member. Can be inserted in Rib 100 is a geometry having a front inclined sidewall that assists the compression member 80 to propagate axially into the connector body 12 and a right angled rear sidewall that prevents the compression member from being inadvertently removed from the connector body. It has a shape. As can be seen in US Pat. No. 5,470,257 (see columns 4, 11. 22-31 and columns 5, 11. 44-55) referenced herein, the height and geometry of the ribs (e.g., front and The inclination of the rear sidewall can be changed so that the compression member is easily assembled and detached from the connector body.

The second end 82 of the compression member is shaped to be engaged by a compression tool (not shown) that slides the first end of the compression member further axially into the inner hole of the connector body 12. The second end of the compression member further includes a flange 94 having a diameter larger than the inner diameter of the second end of the connector body 12. The front side wall 95 of the flange functions as a stopper that restricts the compression member from axially traveling into the connector body during mounting of the cable segment.

The outer surface of the compression member 85 includes an annular groove 86 formed between the first end 82 and the flange 94. According to an exemplary embodiment of the present invention, the annular groove has side walls 92 and 98, which may be perpendicular to the outer surface, the side wall 92 may be perpendicular to the outer surface, and the side wall 98 may be slanted or otherwise Can be surrounded. The first annular shoulder 96 is formed between the first end 84 and the annular groove 86. The diameter of the first annular shoulder 96 is only slightly smaller than the inner diameter of the second end 14 of the connector body to maintain the compression member being inserted axially straight into the connector body. The second annular shoulder 90 is formed on the outer surface between the annular groove 86 and the flange 94. The outer diameter of the second shoulder 90 is sized and shaped to press fit with the inner diameter of the second end 14 of the connector body 12. This press fit keeps the compression member in the connector body sufficient to withstand the tension on the cable segment without being separated from the connector.

The inner surface 83 of the compression member 80 has an arcuate form / shape. According to an exemplary embodiment of the present invention, at least a portion of the inner surface 83 of the compression member 80 tapers inwardly from the first end 82 to the second end 84 of the compression member 80.

Referring to FIG. 3, a segment of braided coaxial cable 200 is initially inserted into an adjacent opening 104 of the connector 10 of FIGS. 1 and 2. Cable 200 includes a center conductor 204 surrounded by dielectric core 202. Braided outer conductor 208 surrounds dielectric core 202 and is folded over a portion of outer protective jacket 206 of cable 200. In order to ensure that the cable 200 is shown in FIG. 3 and properly inserted into the connector 10, the various layers are selectively removed to gradually expose the ends of the center conductor 204 and the ends of the dielectric core 202, The end of braided conductor 208 is then folded over the outer jacket 206. Although not shown in FIG. 3, the cable 200 may have wire sheaths that form one or more foil layer (s) and / or a braided outer conductor to further block the signal transmitted to the center conductor. .

Referring to FIG. 4, the cable 200 is such that the dielectric core 202 is positioned within the hollow 19 of the connector body 12 and one portion of the central conductor 204 of the cable is sleeve 66 of the post 60. It is further inserted into the connector 10 so as to be located within. With this further insertion, the folded end portion 208 of the braided conductor is inserted between the dielectric core 202 and the braided outer conductor 208 over the tapered end of the barb 74 of the post 60. Slide as much as possible.

With the cable 200 further inserted, and as shown in FIG. 5, the sleeve 66 of the post 60 is fully inserted between the dielectric core 202 and the braided conductor 208. Moreover, the center conductor 204 is provided through the guide insulator 50 into the collet of the second end of the conductive pin 40. In this insertion step, the compression member 80 is generally in contact with the outer protective jacket 206 but still does not compress it.

6A and 6B, the connector 10 shows the connector of FIG. 5 with the compression member fully advanced in the axial direction with the cable fully inserted by the compression tool (not shown) in a compressed state. As an example, but not limited to, the compression tool may be held or otherwise engage the second end 84 of the compression member as well as engage the connector body such that the compression member slides in the axial direction and proceeds into the body 12. And the projections 20A, 20B, and 20C of 12 can also be engaged.

When the compression member 80 moves forward in the axial direction, the protruding rib 100 is moved out of the groove 102 of the second end 14 of the connector body 12. Further proceeding, the first annular shoulder 96 cooperates with the inner surface of the second end of the connector body to maintain a straight axial progression of the compression member into the connector body.

As the axial progression continues, the diameter portion that diminishes inwardly of the inner surface 83 of the compression member 80 exerts a radial force inwardly on the inserted portion of the cable 200. Increasing diameter portion of the inner surface 83, the braided outer conductor 208 and the outer protective jacket 206 of the cable 200, the inner surface 83 of the compression member 80 and the sleeve of the post 60 ( Compress and fix between 66). The compression member may be compressed when the annular shoulder 90 is firmly compressed in the second end 14 of the connector body 12 or the side wall 95 of the flange 94 contacts the second end 14 of the connector body. Continue in axial direction until

When the compression member 80 exerts a radial force on the outer jacket 206 of the cable 200, a firm connection is maintained between the cable 200 and the connector 10. As can be seen above, the presence of the grooves 86 relieves significant radial flexibility and stresses during the compression process, and the thickness of the foil of the cable, the braided outer conductor, and the outer connector 10 provided from various manufacturers. This is advantageous because it allows you to adapt to changes such as a protective jacket.

7 and 8 show two different embodiments of the present invention. In FIG. 7, the connector 10a includes a cover element 300 surrounding or enclosing a second end of the compression member 80 made of a durable material such as metal, the second end of the compression member being generally relatively Made of less durable plastic-like material. Therefore, the cover element 300 protects the compression member 80 during and after installation and shields the compression member from the effects of light and the environment.

According to another exemplary embodiment of the invention, the lid element 300 has a cylindrical body 310 and a flanged tip 320 formed to fit around the flange 94 of the compression member 80. The distal end 330 of the cover element fits on top of the connector body 12. The cover element 300 may be disposed in communication with the connector 10 by various techniques, but according to an exemplary embodiment of the present invention, the cover element is mounted on the connector body 12 and the flange 94 of the compression member. Press fit around.

Referring to Fig. 8, another embodiment of the connector 10b of the present invention is shown. In this embodiment, the connector 10b does not include conductive pins and the insulator 30 of the connector 10b is "through" without collets. Thus, when the cable segment 200 is inserted into the connector, the protrusion of the center conductor 202 of the cable is at the same height as the insulator, and the exposed cable segment 204 is the first end 16 of the connector body 12. Escape from). This embodiment provides a number of comparable advantages over the embodiment of FIGS. 1-7, including, but not limited to, cost savings, increased corrosion resistance, and ease of installation.

In summary, in the use of the connectors 10, 10a, 10b of the present invention, the connector may be connected to a port interface (eg, using a tool to tighten the hexagonal plane 26 of the nut portion 24 of the connector body 12). Through 22 to the trunk apparatus port, and then insert a segment of the braided coaxial cable 200 (as shown and described in FIGS. 3-5 and 6A) into the port through the connector, The tool is then used to firmly grip the connector body 12 (eg, by engaging and pressing onto the protrusions 20) to advance the compression member 80 in the axial direction to the second compressed forward position. Thus, using the connectors 10, 10a, 10b according to the present invention simplifies the process and, as described above, generally requires an adapter required to connect the braided coaxial cable with the trunk device ports. I never do that. In addition, proper installation of the connectors 10, 10a, 10b does not require the use of a swivel joint. In turn, this allows the connector 10 to function permanently, and permanent bonding provides a more rigid bond and increased tamper resistance compared to a connector that can be easily returned to its original state using swivel joints and the like.
