Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coaxial cable coupling assembly and a method of connecting a coupling to a coaxial cable. In particular, the present invention relates to a mechanical coupling assembly that, when assembled, provides an environmental and EMI seal between the assembled coupling and the cable.

BACKGROUND OF THE INVENTION Mechanical couplings are used in a variety of applications. In particular, such couplings can be connected (i.e., joined,
connected or combined). Such couplings are used, for example, in connection with CATV cables. There are various types of CATV cables. It is particularly advantageous in the present invention to use two specific types of cables. A first type of cable has a central conductor surrounded by insulation, a rigid electrically conductive outer wall defining a shielding means surrounding the insulation, and a protective jacket surrounding the outer wall. In some newer, more flexible cables of this type, the protective jacket is polyethylene and is bonded to the thin outer wall so that removing or peeling the jacket from the outer wall will damage the thin outer wall.

A second, more flexible type of cable (type)
has a center conductor, an insulating layer surrounding it, an EMI foil shielding surrounding it, a conductive braid (also for EMI shielding) surrounding it, and then a protective jacket surrounding it. Multiple layers of foils and braids are quite often present.

A typical coupling currently used in type cables is a threaded coupling having two external members that are sealed together by O-rings and threaded together. The coupling ring also has two internal members, each internal member having a tapered internal surface. The inner members grip and further deform the wall to a smaller diameter such that the tear ring between the inner members grips the wall at the deformed portion. O
The ring is used to seal the inner and outer members.

Typical couplings currently used on cables have a connector body with one end inserted into the cable between the EMI foil shield and the EMI braid. A narrow ring is placed around the protective jacket adjacent to the area of the cable that is to be connected to the coupling ring. A separate crimping tool is placed around the ring and crimped by applying pressure to the tool. The ring is distorted by pressure and clamps the cable and connector body.

Certain disadvantages are known when using typical couplings in type cables. The use of typical types of couplings for such cables depends on the skill of the operator. When a cable is fitted with a coupling, the coupling must be able to maintain a specified torque for good electrical properties between the coupled cable and the joint, such as the termination to a tap box or connection to another cable. It needs to be tightened to a standard. Stress cracks can occur if the connection between the coupling and the cable is over-tightened and corrosive substances are present. Less tightening will cause EMI
Poor shielding allows cables to be pulled under wind, ice or heat load conditions.

Furthermore, typical mold and mold couplings are dependent on the skill of the operator, as they require stripping off a portion of the protective jacket before connecting the cables. If the stripping operation is performed incorrectly, a portion of the electrical conductor, aluminum foil shielding or braided shielding will be lost and the electrical properties of the cable will suffer.

The stripping operation of both type and type cables is essential for the environmental protection of certain cables, i.e. at particularly important locations (i.e. at cable connections or terminations).
destroy the protective jacket. The stripping operation also slows down the process. The operator must not only work, but must do so with a certain degree of care so as not to unnecessarily destroy the electrical properties or environmental protection of the cable.

Additionally, type cables are often crimped incorrectly. Foils and braids are bundled or broken to reduce the EMI shielding properties of the cable.

Such cables are commonly exposed to the harshest outdoor environments at the point of connection or termination. Such situations include temperature changes of 100°F or more within 24 hours. Additionally, the connection or termination is
Rain, ice, snow, extreme heating and cooling, without damage
Must be able to withstand UV radiation, oxidation, contamination and salt spray.

Additionally, the connections between couplings, cables, and terminations or connections must be sufficiently secure to prevent wind from loosening them. Wind causes sway along the cable line and typically loosens connections between joints and couplings, such as terminations or connections, and between couplings and cables.

Terminated or connected cables must not be susceptible to electromagnetic interference (EMI.electromagnetic interference) or radio frequency interference (RFI.radio frequency interference).
They must be sealed against electromagnetic radiation, also known as interference. Such EMI causes disruptions to aircraft instruments and radar, and is of deep concern to several national and state government agencies.

Typical type and type couplings fail to provide adequate environmental and EMI sealing.
As a result, couplings and/or terminations and connections must be replaced frequently. In addition, poor EMI shielding interferes with the electrical performance of aircraft instruments and radar.

The tolerance limits for typical CATV cables are quite wide. For example, typical 1/2 inch cable diameters vary from 0.493 to 0.507 inches. Typical cable diameter is
It varies from 0.234 to 0.250 inches for RG59U cable. Typical couplings cannot currently handle such wide tolerances.

A specific example of a typical type coupling is disclosed in US Pat. No. 3,551,882 which describes a crimp type coupling for a multiconductor coaxial cable. A malleable ferrule is crimped to the inner braid to terminate the malleable ferrule to the connector, and an outer ferrule is then crimped to the outer braid directly over the inner ferrule to join the outer ferrule to the coupling ring. . An example of a type coupling is disclosed in US Pat. No. 4,346,958 which uses an O-ring to provide an environmental seal.
As mentioned above, it is difficult to achieve a satisfactory seal with O-rings due to the wide tolerance range of cable diameters. Other examples of coaxial cable connectors are disclosed in US Pat. No. 3,336,563 and US Pat. No. 4,400,050.

In addition, a heat recoverable coaxial coupling assembly is disclosed in 1983 relating to a type cable having a connector body having a drive member made of heat recoverable material surrounding a mating area and a mating area.
No. 531,961, filed September 14, 2006. A cable jacket is located between the mating region and the drive member. The drive member is then heated and recovered. The drive member recovers and deforms the cable jacket in the mating area to prevent cable pullout and create an environmental and EMI seal. Although such coupling assemblies are quite effective in overcoming many of the above problems, they require the use of heat. There are situations when heat, especially the heat of a flame, is undesirable.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a central conductor, a surrounding insulating layer thereon, a further surrounding electrically conductive shielding layer, and then a protective outer jacket for environmentally sealing the connection between the coupling and the cable. An object of the present invention is to provide a mechanical coupling assembly for a coaxial cable. Another object of the invention is to provide a method of connecting a coupling to a cable for connecting and terminating such cables such that the connection or termination is environmentally and electrically sealed. It is in.

In order to achieve the above objects and the following objects and advantages, the present invention includes a hollow connector body having a mating region for coupling to a cable, a compression member surrounding the mating region. The compression member is deformable and has sufficient compressive strength to deform the shielding layer of the cable to be connected to the coupling. The coupling further includes mechanical drive means for compressing the compression member. Furthermore, it has further means for forcing the drive means and the connector body towards each other. In addition, it also has further means for concentrating the deformation of the compression member and for sealing the cable and coupling. inserting one or more shielding layers of coaxial cable between the connector body and the compression member, positioning the cable in the mating region, and interconnecting the drive means to the connector body, the compression member in the mating region The cable deforms and deforms itself to fill the void between the substrate, the connector body and the drive means to provide an environmentally and electrically sealed connection.

Generally preferred embodiments of the device are particularly well suited to hollow long substrates and type cables with non-flexible outer walls. Preferred embodiments have sizing means at the forward end of the connector body to provide intimate contact between the rigid outer wall and the connector body over a wide tolerance range for such cables.

Another preferred feature of the coupling according to the invention, which is particularly well adapted to type cables, is anti-rotation means. Anti-rotation means are installed in the mating area. After the drive member and the connector body are interconnected, the rigid wall of the cable is deformed on the anti-rotation means to prevent rotation of the cable relative to the coupling.

A preferred method of connecting the molded cable to the coupling includes removing or hollowing out the insulation between the outer wall and the center conductor in the mating region. This ensures a good electrical connection between the outer wall and the coupling.

Preferred embodiments of couplings for type or type cables include couplings with stop means to prevent over-interengagement, over-tightening or under-tightening of the drive means to the connector body. The stop means for the mold comprises a drive means with a rear face and a connector body with a front face.
When the drive means is sufficiently interconnected with the connector body, each face is coplanar and the coupling is sufficiently sealed to prevent further tightening.

The type cable coupling has a stop means in which the drive means has a rear surface that mates flush with the front surface of the tap box or other termination device when the drive means is fully engaged.

One object of the present invention is to provide a mechanical coupling assembly that environmentally and electrically seals connected cables without requiring stripping of cable protection jackets.

Other objects and advantages of the invention will be better understood from the following detailed description taken in conjunction with the drawings.

It is particularly well suited for connecting two different types of electrical cables. Preferred embodiments are particularly well suited for connection with hollow cables that are surrounded by rigid walls, as detailed below. An example of such a cable, described below, is a type cable. In particular, it is strongly noted that although this cable is illustrated in FIGS. 1 and 2, it is for illustrative purposes only. Although such preferred embodiments are used in practice with a variety of cables, including type cables, they are particularly well suited to type cables. The second preferred embodiment will be explained in detail with reference to FIGS. 3 and 4. This second preferred embodiment is well suited for flexible cables, especially type cables. Such preferred couplings that are particularly well suited to type cables may be used on type cables and other cables as well. The types of cables used in the following detailed description are intended for illustrative purposes only. Both preferred embodiments of the invention have the same basic elements, with certain special features detailed below; namely: (1) having a mating region for engaging the outer layer of the coaxial cable; connector body,
(2) driving means; (3) means for pressing the driving means and the connector body toward each other; and (4) the connector body and the driving means, which are deformed when the driving means and the connector body are pressed toward each other. a deformable compression member disposed therebetween; and (5) means for concentrating the deformation of the compression member deformed by the drive means and the connector body. As used herein, the term "outer layer" of a cable includes any layer outside the insulating area surrounding the central conductor. The mating area may be arranged on the surface of the outer layer of the cable. Typically, the mating region engages an outer layer that is an EMI shielding layer of the cable. In addition, type and type cables include a central conductor surrounded by insulation, a conductive shield layer surrounding the insulation, and other elements of the cable that are surrounded and environmentally protected. It should be understood that this is just an example of, or part of, a larger set with a non-protective jacket. Referring to FIGS. 1 and 2, a coupling 10 of the present invention is shown. The coupling ring has a connector body 12. Connector body 12 is generally cylindrical and hollow. The connector body 12 is a type coaxial cable 1
mating region 14 for engaging outer wall 26 of 6;
has. Connector body 12 has a front threaded outer surface 18 that defines one element of the means for forcing connector body 12 and drive means 32 toward each other. The connector body 12 also has means 20 for preventing rotation of the cable relative to the coupling. The means 20 comprise a hexagonal ring 22 with six edges 24 penetrating only the surface of the outer wall or shielding layer 26 of the cable 16 . Coupling 10 thus resists rotation relative to the cable caused by wind and other forces. The connector body 12 further includes cable sizing means 28 . Typically, shield layer 26 is made from aluminum, which is rigid but malleable. The sizing means 28 comprises an enlarged head 30 having an outer diameter approximately the same as the expected maximum inner diameter of the shielding layer 26 of the cable 16. Connector body 12 with sizing means 28 is adaptable to a wide range of cables and ensures good electrical and physical contact between coupling 10 and cable 16. Preferably, the connector body 12 is made from the same material as the outer wall or shielding layer 26 of the cable 16. Therefore, in this example the connector body 12 is made from aluminum. This prevents corrosion and promotes the environmental and electrical sealing properties of the coupling 10. of course,
Even if shielding layer 26 is made from stainless steel, copper or other materials, connector body 12 can be made to match. Coupling 10 circumferentially surrounds body 12 and is coupled to body 12 by threads 18 and 34.
It has drive means 32 interconnected with. The drive means 32 is hollow, generally cylindrical, and made of the same material as the body 12 for the same reasons stated above. Threads 18 and 34 constitute means for pressing body 12 and drive means 32 towards each other. During initial interconnection, as shown in FIG.
It is between 2. As shown in FIG.
2 and the body 12 is achieved,
The volume of space 36 decreases. Space 36 defines a means for concentrating the deformation of compression member 42. As mentioned above, the coupling has visual means for determining sufficient engagement of the drive means 32 and the body 12. The visual means includes a main body 12 having a front surface 38;
and a drive means 32 having a rear surface 40. Body 12 and drive means 32 are shaped and dimensioned such that when body 12 and drive means 32 are fully interconnected, surfaces 38 and 40 are coplanar with each other. The field operator installing coupling 10 on cable 16 simply tightens drive means 32 to body 12 until surfaces 38 and 40 are coplanar. Even if the operator tightens the coupling ring 10 too much, the force will not be applied to the main body 1.
2 and the cable 16 absorbed by the drive means 32
Do not cause any damage to the product. Coupling 10 further includes a compression member 42 surrounding body 12 in mating region 14 . After the drive means 32 and the body 12 are fully interconnected, the compression member contacts the cable 16 at least in the anti-rotation means. This secures the cable 16 at the edge 24 as described above,
Rotational movement of cable 16 relative to body 12 is prevented. Although the compression member 42 is deformable, as shown in FIG.
4 and has sufficient compressive strength to deform the outer wall 26. ASTM (American Society for
The compression member 42 has a pressure of at least 2000 psi, as measured in accordance with Testing and Materials method) D695;
Preferably 2000-40000psi, most preferably
It has a compressive strength of 7100psi. A currently used material that satisfies these conditions is polytetrafluoroethylene. Furthermore, polyvinyl chloride, polyethylene, fluorine-containing ethylene/propylene copolymers, and aluminum 1100-0 are also known to have the above properties. Compression member 42 has many advantages. An example is given below. In connector assembly, the compression member 42 can grip the cable jacket and pull the cable into the connector during the final stages of assembly to ensure a good electrical connection.
Compression member 42, when used in the form of a ring, can be split to facilitate fitting the ring onto cables of various sizes. The crack is then closed during assembly of the connector and a good seal is obtained. By using a suitable material as the compression member, it is possible to force a small portion of material out from between the cable jacket and the drive means 32 under pressure during the final stage of assembly, and the environmental seal is achieved. enhanced and provides visual indication of proper assembly. As mentioned above, a space 36 is defined when drive means 32 and body 12 are first interconnected. Compression member 42 surrounds mating region 14 and is located in space 36 . Volume of compression member 42
V ₁ is such that upon sufficient interconnection of drive means 32 and body 12 the spatial volume V ₂ is equal to V ₁ . In this example, the means for concentrating the deformation of the compression member 42 is a curved surface 37 that concentrates the force from the deformation of the compression member 42 towards the mating region 14, deforming the cable outer wall 26 and the protective jacket 44. and form the desired environmental and electrical seal. In use, cable 16 is removed from coupling 1 by removing insulation 46 from the cable.
Provided for connection with 0. The outer wall 26 is arranged to surround the mating region 14 and tightly engages the anti-rotation means 20 . cable 16

has. After the cable has been installed as described above, the compression member 42 is located on the cable 16 and surrounds the jacket 44 in the mating region 14 and in particular in the anti-rotation means 20. The drive means 32 is slid onto the cable 16 and then moves the connector body 12 by engaging the threads 34 with the threads 18.
interconnect with. The drive means 32 is clamped to the body 12. When the twisting operation is performed, the compression member 42 is deformed and compressed. The deformation and resulting compression causes the body 12
and the driving means 32. As the volume of space 36 decreases, it becomes more compressed and more compressive force is concentrated on cable 16. As clearly shown in FIG. 2, the compressive force of compression member 42 deforms the cable, effectively securing it in place in connector body 12. The combination of the shape of compression member 42 and the surface penetration of edge 24 into outer wall 26 prevents cable withdrawal. When an axial withdrawal force is applied to the cable, for example in the direction of arrow 52, a normal force is generated on the drive means 32 and compression member 42 combination. Since the wall 26 is deformed, a component of the axial force is applied to the normal force of the drive means and compression member 42.
Distortion of the cable 16 is reduced and cable pull-out is effectively prevented. Since no stripping operation is necessary, the protective jacket 44 of the cable 16 sufficiently covers the cable 16 even after connection with the coupling 10. Cable 16 maintains all environmental protection. After sufficient interconnection, the volume V ₁ of the compression member 42 is reduced to the space 36
will be equal to the volume of V ₂ . Since there is no air gap to trap corrosive substances, the connected cable 1
6 as well as the coupling 10 are environmentally sealed. It is especially important to have intimate contact between the connector body 12 and the outer wall shielding layer 26 because it prevents EMI leakage and effectively electrically seals the connected cable 16. The connector body 12 has threads 50 for connecting to a compatible terminal board, junction box, female connector for connecting to other cables, or other elements.
is supplied. With particular reference to FIGS. 3 and 4, there is shown another preferred coupling 110 having the following elements which function similarly as described above with the following exceptions; connector body 1 having mating area 114;
12, a drive means 132 having a thread 134 and a rear surface 140, and a compression member 142. Coupling assembly 110 is connected via threads 154 to a wall mount unit 152 of FIG. 3, such as a tap box, and is typical of type cable 116 of FIG. There is. In this type of cable, weak foil shielding 15
6 and the braided layer 158 need to be separated. Connector body 112 includes weak foil 156 and braided layer 15
The sharp end 11 intersects between 8
5 and mating area 1 for contacting the braided layer.
It has 14. This long, sharp portion 115 of the connector body 112 actually separates the braided layer from the foil shielding when the connector body 112 is placed over the cable 116, and the outside of the portion 115 of the connector body 112, i.e., the mating A visual means is provided for the operator to ensure proper positioning in area 114. In this aspect of the invention, extending the insulation and foil beyond the distal end of the connector body 112 provides another visual inspection opportunity for the operator to ensure proper separation of the foil shielding 156 and the braided layer 158. is supplied. After visually inspecting the foil shield to ensure that it is not damaged, the insulation and foil are trimmed flush with the end of the connector body, leaving the center conductor stretched to the extent required. It will be done. Some types of cables have a foil shield that is bonded to the insulation to ensure that the foil remains intact during connector installation. In use, the cable 116 is connected by first connecting the cable 116 to the mating region 114.
is connected to coupling assembly 110. This operation is performed without damage to the cable by applying appropriate pressure and the cable is electrically sealed. The drive means 132 and compression member 142 are slid onto the cable before engaging the distal end 115 with the cable. The drive means 132 then connects the wall mount unit 1 by screw threads 134 and 154.
52 , thus providing means for pressing the connector body 112 and the drive means 132 towards each other and deforming the compression member 142 . A space 136 is defined between the drive means 132 and the body 112 in a manner similar to that described with reference to FIGS. 1 and 2. The drive means 132 is tightened until its face 140 abuts the face 160 of the wall-mounted unit 152. In this position, the volume of space 136 is slightly smaller than the volume of compression member 142;
A protrusion 124 is formed on the cable protection jacket 144 that serves to secure the cable 116 to the body 112. Since stripping of the protective jacket on the outside of coupling ring 110 is not required, cable 116 remains environmentally sealed. Coupling 110 is environmentally sealed by the use of compression member 142 and by having surfaces 140 and 160 coplanar. In addition, coupling 110 is provided with a washer 162 that environmentally seals the connection between coupling assembly 110 and wall 152 when compressed. In addition, the coupling 110 includes an arrow 152.
Means are provided for preventing cable pullout in response to a force in the direction of the cable. This means acts substantially in the same way as the anti-rotation means 24 and consists of a protrusion 124 formed upon connection by the volume difference between the space 136 and the compression member 142 as described above. The connector body 112 is provided with a shoulder 148 to ensure good electrical contact with the wall unit 152 and to provide foil shielding, a braided layer and maximum electrical continuity from the connector body 112 to the wall unit 152. has been done. In some cases, the portion 115 of the connector body is deformed radially inward to maximize electrical contact with the foil shield 156 as well as to deform the cable protection jacket 144 and braided layer 158 radially inward. Also, EMI shielding may be improved in the mating region 114 between the portion 115 of the connector body 112 and the foil shield 156 by providing a well-concentrated force from the deformation of the compression member 142. desirable. This may be due to the volume of compression member 142 relative to space 136 and/or connector body 1
This is achieved by adjusting the external shape of 12 and the internal formation of drive means 132. Such optimizations of the invention will be apparent to those skilled in the art implementing the various advantages provided by the invention. The coupling assembly of the present invention forms a secure connection with the cable. This provides a pressure seal that further helps protect the cable and coupling from environmental damage. The invention is particularly useful because it involves connecting mechanical coupling assemblies of the type described above without stripping the outer protective jacket of the cable. The method of the invention comprises providing a coupling assembly of the above type and inserting the cable into the connector body such that the outer conductor contacts the connector body in the mating area without peeling off the protective outer jacket;
A compression member is arranged to surround the cable in the mating region, a driving means is arranged to surround the compression member, and the driving means is pressed against the connector body so that the compression member deforms the cable toward the connector body. concentrating the deformation of the compression member so as to secure the compression member in position and filling the gap between the connector body and the drive means;
It thus includes making connections that are electrically and environmentally sealed. Although the present invention has been described with reference to the embodiment considered to be the most practical, it goes without saying that other shapes that do not depart from the technical idea of the present invention are also embodiments of the present invention.
