Abstract

A coaxial cable connector includes a barrel having a longitudinal axis and an inner compression band formed on the outer barrel. A coaxial fitting is mounted to the front end of the outer cylinder for connection to an electrical device, and a coaxial compression collar is attached to the outer cylinder. An outer compression band is formed on the compression collar to reflect axial compression of the coaxial cable connector and to move between an uncompressed state and a compressed state. The outer compression band moves from an uncompressed state to a compressed state, deforming the inner compression band into a pawl that allows the coaxial cable to be introduced into the coaxial cable connector and later prevent the coaxial cable from coming out of the coaxial cable connector .

Description

Coaxial cable connector with alignment and compression features

Broadly speaking, the present invention is an electrical device, and in particular, a coaxial cable connector.

Coaxial cables transmit radio frequency ("RF") signals between the transmitter and the receiver and are used to interconnect televisions, cable boxes, DVD players, satellite receivers, data machines, and other electrical devices. A typical coaxial cable includes an inner conductor surrounded by a flexible dielectric insulator, a foil layer, a conductive metal tubular sheath or shroud, and a polyvinyl chloride shield. A radio frequency signal is transmitted via the inner conductor. The conductive tubular shield provides grounding and inhibits electrical and magnetic interference with the RF signal of the inner conductor.

The coaxial cable needs to be equipped with a cable connector to interface with the electrical device. The coaxial cable connector generally has a connector body, a threaded fitting mounted on one end of the connector body for rotation, a hole extending from an opposite end to the connector body to receive the coaxial cable, and a hole An inner cylinder within the bore and in electrical communication with the fitting. Typically, the coaxial cable connector is crimped onto one of the prepared ends of the coaxial cable to secure the connector to the coaxial cable. However, the crimping sometimes crushes the coaxial cable to cause leakage, interference, or poor grounding, resulting in deterioration of signal transmission. In addition, due to some When the connectors are mounted on the connector body, they are too tightly packed, so that it is very difficult to lock the connector to the electrical device; and some connector fittings are too loose on the connector body, resulting in loose connectors. The electrical connection between the fitting and the inner cylinder is interrupted by the fitting being detached from the inner cylinder.

In accordance with the principles of the present invention, an embodiment of a coaxial cable connector includes an outer cylinder, a compression collar applied to the rear end of the outer cylinder, and a threaded fitting mounted for rotation on the front end of the outer cylinder. The outer cylinder has an inner compression band and the compression collar has an outer compression band surrounding the inner compression band formed on the outer cylinder. The inner compression band and the outer compression band react axially with compression of the coaxial cable connector to move between uncompressed and compressed positions. In the compressed state, the outer compression band abuts the inner compression band to deform the inner compression band radially inward.

In accordance with the principles of the present invention, a specific embodiment of the coaxial cable connector includes a cylindrical body, a fitting mounted to the body for rotation, and an alignment mechanism disposed between the body and the fitting. The alignment mechanism is compressed between the body and the fitting to apply an axial force to the fitting to maintain contact between the fitting and the body. The alignment mechanism includes a quasi-annular spring formed integrally with the body.

In accordance with the principles of the present invention, a specific embodiment of the coaxial cable connector includes an outer barrel having a longitudinal axis, the outer barrel being formed with a compression band. A coaxial fitting is attached to the front end of the outer cylinder for attachment to the electrical device. A coaxial compression collar is mounted on the outer cylinder. An outer compression band formed in the compression collar reflects the axis of the coaxial cable connector Moving to compression and between uncompressed and compressed states. Movement of the outer compression band from the uncompressed state to the compressed state forms the inner compression band into a pawl for directing the coaxial cable into the coaxial cable connector and preventing the cable from coming out of the coaxial cable connector.

Returning to Figure 2B, the nut portion 34 of the threaded fitting 25 is mounted to the forward end 23 of the body 22 for rotation about the axis A. The threaded fitting 25 is made of strong, hard, rigid and durable A material or combination of materials, such as a metallic material, that is characteristic of a highly conductive material.

Still referring to FIG. 2B, the compression collar 26 has opposite front and rear ends 42 and 43, an annular side wall 44 extending between the front and rear ends 42 and 43, and one on the annular side wall 44. An annular outer compression band 45 is formed along the axis A about the middle of the front and rear ends 42 and 43 of the compression collar 26. Referring now to Figure 3A, the compression collar 26 has a smooth annular outer surface 50 and a smooth annular inner surface 51 opposite thereto. The inner space 52 bounded by the annular inner surface 51 extends into the compression collar 26 from the mouth 53 formed at the rear end 43 of the compression collar 26 to the opening 54 formed at the front end 42. The annular inner space 52 is in the shape of a hole and is sized to receive the coaxial cable 21. The compression collar 26 is frictionally fitted to the rear end 24 of the body 22 closest to the opening 54 to respectively restrict the body 22 and the compression collar 26 from being radially or radially along the axis A, Relative movement and rotation of the axial direction. The compression collar 26 is constructed of materials that are strong, hard, rigid, and durable, such as materials such as metal or plastic, or a combination of materials.

With continued reference to FIG. 3A, the body 22 of the coaxial cable connector 20 is an assembly including a cylindrical outer barrel 60 and a cylindrical, coaxial inner post 61 disposed within the cylindrical outer barrel 60. The coaxial inner column 61 is an elongated sleeve that extends along the axis A and is rotationally symmetric about the axis A. The coaxial inner column 61 has front and rear ends 62 and 63 that face each other, and inner and outer surfaces 64 and 65 that face each other. The outer surface 65 at the rear end 63 of the coaxial inner column 61 forms two annular ridges 70a and 70b that project toward the front end 62 and project radially outward from the axis A. The term "radial" is used here to mean The radii extending from the axis A are aligned, and the "axial" means extending or aligning parallel to the axis A. The annular ridges 70a and 70b are spaced apart from each other along the rear end 63 of the coaxial inner column 61. The annular ridges 70a and 70b grasp the cable when the coaxial cable is attached to the coaxial cable connector 20.

Referring now to the enlarged view of FIG. 3C, the outer surface 65 of the coaxial inner column 61 has a series of outwardly facing flanges 66a, flanges 66b, flanges 66c, flanges 66d and flanges 66e at the coaxial inner column 61. A space is formed near the front end 62. Each flange has a similar structure and projects radially away from the axis A; the flange 66a and the flange 66d each include a front surface facing the front end 62 of the coaxial inner column 61, and toward the coaxial inner column 61 The rear end of the rear end 63; the flange 66b and the flange 66c each include a rear surface facing the rear end 63 of the coaxial inner column 61; and the flange 66e includes a front end 62 facing the coaxial inner column 61. Positive. Each of the flanges 66a to 66e extends outwardly from the axis A by a different radial distance. The flange 66a and the flange 66b define an annular groove or passage 71 around the coaxial inner column 61 defined between the front face of the flange 66a and the rear face of the flange 66b. The cylindrical outer cylinder 60 engages the coaxial inner column 61 at the annular groove or passage 71.

Still referring to FIG. 3C, the rear end 32 of the threaded fitting 25 engages the grooved inner surface 41 of the nut portion 34 at the annular groove or channel 74 at which the coaxial inner column 61 is The outer surface 65 and the rear surface of the flange 66d form a first annular volume 72 between the coaxial inner column 61 and the nut portion 34 for receiving an annular gasket 73. In addition, the groove-shaped inner surface 41 of the nut portion 34 at the annular groove or passage 75 is coupled to the front surface of the flange 66d and the coaxial inner column 61. The outer surface 65 at the flange 66e forms a second annular volume 80 between the coaxial inner column 61 and the nut portion 34 for receiving an annular gasket 81. The threaded fitting 25 is supported by the annular gaskets 73 and 81 and carried on the coaxial inner column 61, and the annular gaskets 73 and 81 prevent moisture from entering the connector 20. The coaxial inner column 61 is composed of a material or a combination of materials having a hard, rigid, durable, highly conductive material property, such as a metal material, and the annular gaskets 73 and 81 are deformable, elastic, and have shape memory characteristics. Made up of materials or combinations of materials.

Returning to Fig. 3A, the cylindrical outer cylinder 60 is an elongated cylindrical sleeve extending along the axis A and rotationally symmetric about the axis A. The cylindrical outer cylinder 60 has a side wall 150 having opposite front and rear ends 82 and 83, and opposite inner and outer surfaces 84 and 85. The inner surface 84 defines and defines an inner cable receiving space 90 that is shaped and sized to receive the coaxial cable 21 and to place the rear end 63 of the coaxial inner post 61 therein. An opening 91 at the rear end 83 of the cylindrical outer cylinder 60 communicates with the inner space 52 of the compression collar 26 and opens into the inner cable receiving space 90. The front end 82 of the cylindrical outer barrel 60 defines an inwardly projecting annular end edge 92. The annular end 92 abuts the annular groove or channel 71 and is received in frictional engagement to secure the cylindrical outer barrel 60 to the coaxial inner column 61. The annular end edge 92 plus the body front end 23 and the threaded fitting 25 rear end 32 define a circumferential groove 87 extending from the outer surface 85 of the cylindrical outer cylinder 60 into the connector 20.

The front end 82 of the cylindrical outer cylinder 60 integrally defines an alignment mechanism 93 disposed in the circumferential groove 87 between the cylindrical outer cylinder 60 and the threaded fitting 25 so as to be An axial force is applied between the cylindrical outer cylinder 60 and the threaded fitting 25 to maintain contact between the threaded fitting 25 and the coaxial inner column 61 of the body 22. 2C shows the cylindrical outer cylinder 60 alone, in which the alignment mechanism 93 includes two reeds 94 and 95 between the annular end edge 92 and the periphery 85a of the cylindrical outer cylinder 60 along the inner surface 84. . The reed 94 is a quasi-annular piece having opposite ends 94a, ends 94b and a central portion 94c. The reed 95 is a quasi-annular piece having opposite ends 95a, ends 95b and a central portion 95c. As used herein, "quasi-annular" means the shape that extends across an arcuate segment of a portion of the full circumference. The reeds 94 and 95 are formed from a flat, thin and elongated spring material. The reeds 94 and 95 are quasi-annular with respect to the axis A. The ends 94a and 94b of the reed 94 are fixed to the front end 82 of the cylindrical outer cylinder 60, and the middle portion 94c is disengaged from the front end 82 and protrudes from the cylindrical outer cylinder 60 toward the threaded fitting 25 in the axial direction. Therefore, the reed 94 has an arcuate curved shape across the radial direction and a convex shape in the axial direction. The reed 94 is bent along the axis A in response to axial compression, and the reed 94 maintains a compressed state, the central portion 94c being closest to the front end 82. When the reed 94 is in the compressed state, the central portion 94c is disposed along the periphery 85a between the side of the annular end 92 and the inner surface 84 of the cylindrical outer cylinder 60, and the reed 94 is forward An axial force is applied to the threaded fitting 25.

Similarly, the ends 95a and 95b of the reed 95 are fixed to the front end 82 of the cylindrical outer cylinder 60, and the central portion 95c is separated from the front end 82 and axially from the cylindrical outer cylinder 60 toward the threaded fitting. The protrusions 25 have the reed 95 having an arcuate curved shape in the radial direction and a convex shape in the axial direction. The reed 95 is bent along the axis A in response to axial compression, and the reed 95 maintains a compressed state, the central portion 95c Close to the front end 82. When the reed 95 is in a compressed state, the central portion 95c is disposed between the side of the annular end 92 and the inner surface 84 of the cylindrical outer cylinder 60, and the reed 95 exerts an axial force forward. To the threaded fitting 25 above. In other embodiments, the alignment mechanism 93 includes a plurality of reeds, or a circular disk or an annulus mounted on the post at the front end 23 of the cylindrical outer cylinder 60. These additional embodiments of the alignment machine 93 have an annular sinusoidal or helical surface shape about the axis A and four circumferentially spaced apart forwardly projecting contact points to bear against the threaded fitting 25 .

Referring now to Figure 3C, the threaded fitting 25 is mounted on the coaxial inner column 61 but is free to rotate about the axis A. In order to allow free rotation, the ring seals 73 and 81 radially separate the threaded fitting 25 from the coaxial inner column 61, creating a gap 86 that allows slight movement in the radial direction to allow the threaded fitting 25 to The rotation on the ring seals 73 and 81 has a lower rolling friction. When the threaded fitting 25 is loaded on the body 22 and locked or engaged to an electrical device, the alignment mechanism 93 maintains a compressed state, and the force applied by the alignment mechanism 93 advances in the direction of the line B of FIG. 3C. The threaded fitting 25 is pressed such that the alignment mechanism 93 abuts the threaded fitting 25 such that the contact surface 101 on the rear end 32 of the threaded fitting 25 contacts the rear surface of the flange 66c, that is, the contact surface 102. The alignment mechanism 93 applies a force forward to overcome the force in the rearward direction caused by the compression of the ring seal 73 in the first annular volume 72. Establishing a permanent low friction connection in this manner allows the threaded fitting 25 to freely rotate on the coaxial inner column 61 and maintain a permanent electrical connection of the threaded fitting 25 with the coaxial inner column 61.

The cylindrical outer cylinder 60 is constructed of a material or combination of materials having strong, rigid, size and shape memory, electrical insulation, and low coefficient of friction materials such as plastic. The alignment mechanism 93 integrally formed with the cylindrical outer cylinder 60 also has a strong, rigid, size and shape memory, and an electrically insulating material characteristic. Therefore, the compression of the alignment mechanism 93 causes the alignment mechanism 93 to generate and Compressing the reaction in the opposite direction causes the alignment mechanism 93 to have an original configuration that tends to return to alignment and coaxial with the axis, while maintaining the threaded fitting 25 coaxial with the axis A.

With continued reference to FIG. 3C, the reeds 94 and 95 are circumferentially and radially offset from each other within the circumferential groove 87. The central portions 94c and 95c are offset in the radial direction to provide a uniform applied force from both sides of the body 22 toward the threaded fitting 25. The arcuate convex shape of the reeds 94 and 95 can react to the backward movement of the threaded fitting 25 to generate a reaction force when the threaded fitting 25 is locked or connected to an electrical device, thereby maintaining the threaded fitting 25 at the axis A concentrically aligned state maintains continuity of the connection between the contact faces 101 and 102 completely about the coaxial inner column 61. The alignment and connection maintenance ensures that signals transmitted through the connector 20 do not leak out of the connector 20, and that external interfering RF signals do not leak into the connector 20, which maintains electrical ground. Moreover, the interaction of the two central portions 94c and 95c with the rear end 32 of the threaded fitting 25 is also lower due to the material construction of the structural features and the limited point of interference between the threaded fitting 25 and the alignment mechanism 93. The coefficient of friction. In other embodiments of the alignment mechanism 93, the four contact points of the alignment mechanism 93 are evenly distributed such that the force distribution applied to the threaded fitting 25 at the four contact points is averaged.

Returning to Figure 3A, the rear end 83 of the cylindrical outer barrel 60 carries the compression collar 26. The side wall 150 of the cylindrical outer cylinder 60 is reduced in thickness near the rear end 83 to form an inner compression band 152. Referring now to the enlarged view of FIG. 3D, the inner compression band 152 includes a main ridge portion 103, a sub ridge portion 104, and a curved portion 105 formed therebetween. The main ridge portion 103 and the sub ridge portion 104 have vertical ridges that protrude radially outward from the axis A. The main ridge portion 103 is formed near the rear end 83, and the sub ridge portion 104 is formed before the main ridge portion 103, the curved portion 105 being the side wall 150 between the main ridge portion 103 and the sub ridge portion 104. Flexible thin section. The inclined first face 110 of the main ridge portion 103 is a disturbing face toward the rear end 83 of the cylindrical outer cylinder 60, and the inclined second face 111 faces the front end 82 of the cylindrical outer cylinder 60. The inclined first face 112 of the secondary ridge portion 104 is an interference face toward the rear end 83 of the cylindrical outer cylinder 60, and the inclined second face 113 faces the front end 82 of the cylindrical outer cylinder 60. A V-shaped passage 114 is formed between the inclined first surface 111 and the inclined second surface 112. The main ridge portion 103 and the sub ridge portion 104 are carried by a thin-walled ring 115 on the rear end 83 of the cylindrical outer cylinder 60 with respect to the inner cable receiving space 90, and the annular ridge 70a on the coaxial inner column 61. Separated from 70b. The thin-walled ring 115 is flexible and deflects inwardly in the radial direction in response to the application of a radially directed force toward the axis A. As for the annular shoulder 116 inside the thin walled ring 115, there is a vertical abutment surface 120 adjacent the outer surface 85 of the cylindrical outer cylinder 60.

Referring again to FIG. 3D, the annular sidewall 44 of the compression collar 26 is narrowed at the front end 42 to form the annular outer compression band 45. The compression collar 26 includes a forward from itself An extended ring 122, an inclined surface 133 disposed adjacent to the annular outer compression band 45 and disposed between the annular outer compression band 45 and the annular inner surface 51, and a rear end 43 of the compression collar 26 and the annular portion An annular vertical shoulder 134 formed adjacent the surface 51. The annular outer compression band 45 is a narrowed, recessed portion of the annular side wall 44 that extends into the inner space 52 and has an inner surface 123 and an opposite outer surface 124, a first wall portion 125, and an opposite The second wall portion 126 and the flexible bending portion 130 are formed by joining the first and second wall portions 125 and 126. The first and second wall portions 125 and 126 are rigid, and the curved portion 130 is a living hinge that provides resiliency between the first and second wall portions 125 and 126. The first and second wall portions 125 and 126 of the annular outer compression band 45 constitute a compression space 131. The ring 122 extends forwardly from the second wall portion 126 and terminates at the terminal edge 132, juxtaposed with the abutment surface 120 of the annular shoulder 116.

Still referring to FIG. 3D, the compression collar 26 fits over the cylindrical outer barrel 60, tightly surrounding the cylindrical outer barrel 60, and the annular inner surface 51 of the compression collar 26 frictionally engages the cylindrical shape The annular outer surface 85 of the outer cylinder 60 limits relative movement in radial, axial and rotational directions of each other. The inner compression band 152 of the cylindrical outer cylinder 60 receives and engages the annular outer compression band 45 of the compression collar 26 to limit relative radial, axial and rotational relative movement of the compression collar 26, the annular vertical The shoulder 134 is spaced from the rear end 82 of the cylindrical outer cylinder 60. The inclined surface 133 of the compression collar 26 is juxtaposed with the inclined first face 110 of the main ridge portion 103. The inner surface of the annular outer compression band 45 The first wall portion 125 is juxtaposed with the inclined second surface 111 of the main ridge portion 103, and the curved portion 130 is received in the V-shaped passage 114. Inwardly against the curved portion 105, the inner surface 123 of the annular outer compression band 45 is juxtaposed along the second wall portion 126 with the inclined first surface 112 of the secondary ridge portion 104, and the compression collar 26 The terminal edge 132 is juxtaposed with the abutment surface 120 of the cylindrical outer cylinder 60, and such an arrangement constitutes a state in which the compression collar 26 is fitted on the cylindrical outer cylinder 60.

The cable connector 20 is used to connect the coaxial cable 21 to an electrical device for electrical communication during operation. To achieve this, the cable connector is attached to the coaxial cable 21 as shown in Fig. 4A. When the coaxial cable 21 is ready to receive the coaxial cable connector 20, a portion of the protective cover 140 of one end 141 of the coaxial cable 21 is first stripped to expose the inner conductor 30, the dielectric insulator 143, the foil layer 144, and the flexible Sleeve 145. The dielectric insulator 143 is stripped rearward to expose the inner conductor 30 of a predetermined length, and the end of the flexible sheath 145 is folded back to expose a portion of the shield 140. The end 141 of the coaxial cable 21 is then inserted into the connector 20 to arrange the connector 20 in an uncompressed state as shown in Figure 4A. In this state, the coaxial inner column 61 is disposed between the flexible sheath 145 and the foil layer 144 and is in electrical communication with the flexible sheath 145.

Still referring to FIG. 4A, in order to dispose the coaxial cable connector 20 on the coaxial cable 21 in an uncompressed state, the coaxial cable 21 is aligned with the axis A and penetrates the compression collar 26 in the direction indicated by the arrow C. Inner space 52. The coaxial cable 21 then passes through the opening 91 into the inner cable receiving space 90 surrounded by the coaxial inner column 61, thereby ensuring that the inner conductor is aligned with the axis A. The coaxial cable 21 continues to move forward along the line C in FIG. 4A until the coaxial cable 21 hits the coaxial inner column 61. End 63, the flexible sheath 145 is advanced on the rear end 63, the annular ridges 70a and 70b are placed in contact with the flexible sheath 145, and the flexible sheath 145 is folded back. Portions of the seal 140 are in contact with the inner surface 84 of the cylindrical outer cylinder 60. The foil layer 144 and the dielectric insulator 143 also advance within the coaxial inner column 61 against the inner surface 64 of the coaxial inner column 61. The coaxial cable 21 is further advanced along line C to the position shown in FIG. 4A, wherein the free end of the dielectric insulator 143 is disposed within the nut portion 34 of the threaded fitting 25 and the inner conductor 30 passes through the ring portion 33. The inner space 37 protrudes beyond the mouth 38 of the threaded fitting 25. In this configuration, the flexible sheath 145 is in electrical communication with the outer surface 65 of the coaxial inner column 61. In addition, since the alignment mechanism 93 biases the threaded fitting 25 into permanent electrical communication with the coaxial inner column 61, the flexible sheath 145 is also in electrical communication with the threaded fitting 25 via the coaxial inner column 61. Therefore, the coaxial cable connector 20 and the coaxial cable 21 establish a shield and ground continuity. Referring to Figures 3D and 4A, in the uncompressed state of the connector 20, the inner diameter of the cylindrical outer cylinder 60 is D, and the inner surface 84 of the cylindrical outer cylinder 60 is spaced from the annular ridge 70a and the annular ridge 70b. The opening distance is G, and the length of the connector 20 from the front end 23 to the rear end 43 is L. In the embodiment in which the connector 20 is used in an RG6 type coaxial cable, the inner diameter is about 8.4 mm, the distance G is about 1.4 mm, and the length L is about 19.5 mm. Other embodiments, such as for other types of coaxial cables, will come in different sizes. The coaxial cable connector 20 is moved from an uncompressed state to a compressed state as shown in FIG. 4B, and the thin cylindrical inner and outer compression bands 152 and 45 of the cylindrical outer cylinder 60 and the compression collar 26 are used for crimping downward. To the coaxial cable 21 for connection on the coaxial cable The device 20 provides a secure, damage-free connection between the coaxial cable 21. To compress the connector 20, the connector 20 is placed in a compression tool that grasps the connector 20 and along the axis A of the axis A from the arrow lines E and F. The front and rear ends 23 and 43 compress the connector 20.

Figure 5 is an enlarged view of the rear end 24 of the body 22 and the compression collar 26, wherein the coaxial cable 21 has been installed. When the compression tool is operated, the rear end 43 of the compression collar 26 reacts with the axially applied compressive force toward the cylindrical outer cylinder 60, causing the compression collar 26 and the circular outer cylinder 60 to compress the ring, respectively. Outer and inner compression bands 45 and 152. When the abutment surface 120 is advanced toward the compression collar 26, the inclined surface 133 of the annular outer compression band 45 strikes the inclined first face 110 of the main ridge portion 103 of the inner compression band 152. The inclined surface 133 and the inclined first surface 110 are biased to face each other and are parallel to each other, and the inclined surface 133 and the inclined first surface 110 slide each other in a direction oblique to the axis A. The rear end 83 of the cylindrical outer cylinder 60 contacts and abuts against the annular vertical shoulder 134 of the compression collar 26, the rear end 83 being in the ring when the inclined first face 110 slides beyond the inclined surface 133 The vertical shoulder 134 is twisted inwardly and the thin walled ring 115 is deformed inwardly such that the inner compression band 152 snaps radially inwardly and the V-shaped channel 114 deforms inwardly. When the V-shaped channel 114 is deformed inwardly, the annular outer compression band 45 snaps into the V-shaped channel 114 under a sustained compressive force. The first and second wall portions 125 and 126 are angled inwardly toward the axis A such that the axial compressive force causes the first and second wall portions 125 and 126 to deform inwardly toward the axis A in the radial direction. The curved portion 130 is forced to enter the V-shaped passage 114 radially inwardly and against the curved portion 105 to radially inward the inner compression band 152 Internal deformation. The V-shaped channel 114 grasps the outer compression band 45 of the buckle, ensuring that the outer compression band 45 is snapped in the radial direction, and when the primary and secondary ridge portions 103 and 104 react to twist and react with the outer compression band 45 When buckled by contact, the outer compression band 45 is further directed radially inwardly by the deformed V-shaped channel 114 to the annular ridges 70a and 70b.

The compression continues until the outer compression band 45 is closed and the compression space 131 is eliminated, and the connector 20 is placed in a compressed state as shown in Figs. 3B, 4B and 5. Although the process of moving the coaxial cable connector 20 from the uncompressed state to the compressed state is presented and illustrated in a series of steps, it should be understood that the connector 20 is compressed onto the coaxial cable 21, preferably in a smooth manner. Completed in a continuous operation that takes less than one second. In the compressed state of the coaxial cable connector 20, the inner diameter D of the connector 20 becomes the inner diameter D', and the inner surface of the cylindrical outer cylinder 60 is separated from the barb 70 by G', and the connection is now The length of the body 22 of the device 20 is now L', as shown in Figures 4B and 5. The distance G' is less than half of the distance G, and the inner diameter D' is about the inner diameter D minus the distance G', and the length L' is less than the length L. In the embodiment in which the connector 20 is used in an RG6 type coaxial cable, the inner diameter D' is about 6.7 mm, the distance G' is about 0.5 mm, and the length L' is about 18.0 mm. In other embodiments for other types of cables, there will be different sizes. As shown in FIG. 4B, the diameter reduction is such that the shield 140 of the coaxial cable 21 and the flexible sheath 145 are joined and crimped between the curved portion 105 and the annular ridges 70a and 70b. Furthermore, the curved portion 105 facing away from the annular ridges 70a and 70b is placed between the annular ridges 70a and 70b, so that the shield 140 and the flexible sheath 145 are at the annular ridges 70a and 70b. The axial position therebetween is crimped between the curved portion 105 and the annular ridges 70a and 70b to prevent the coaxial cable 21 from coming off the connector 20. The first and second wall portions 125 and 126 are oriented transversely and tangential to the axis A, thereby supporting the inner compression band 152 of the buckle in the snap-fit position and preventing the inner compression band 152 from moving outwardly to prevent the coaxial cable 21 was taken out.

Referring again to FIG. 5, the hard material properties of the coaxial inner post 61 prevent the coaxial inner post 61 from being damaged by crimping. In addition, since the dielectric insulator 143 and the inner conductor 30 are protected in the coaxial inner column 61, and the flexible sheath 145 is in contact with the outer surface 65 outside the coaxial inner column 61, the The continuous connection between the flexible sheath 145 and the coaxial inner column 61 is such that the signal transmitted in the coaxial cable connector 20 does not leak outside the connector 20, and the external RF signal does not leak into the connector. Within the connector 20, the connector 20 can also maintain electrical grounding. The interaction between the flexible sheath 145 and the annular ridges 70a and 70b (both forward and radially toward the axis A) further prevents the coaxial cable 21 from facing away from the line F direction, and is detached rearward from the coaxial Cable connector 20.

Referring to Figures 7A and 8A, in the uncompressed state of the coaxial cable connector 20, the inner diameter of the cylindrical outer cylinder 60 is J, and the inner surface 284 of the cylindrical outer cylinder 260 is separated from the annular ridges 270a and 270b. The distance is K, and the length of the coaxial cable connector 220 at the front end 223 of the cylindrical outer cylinder 260 to the rear end 243 of the compression collar 226 is M. In a specific embodiment of the coaxial cable connector 220 for an RG6 type cable, the inner diameter J is about 8.4 millimeters, the distance K is about 1.4 millimeters, and the length M is about 19.5 millimeters. Other specific embodiments, such as for other types When the cable is in, there are different sizes.

The coaxial cable connector 220 is axially compressed to move from an uncompressed state to a compressed state as shown in Figure 8C. The thin outer and inner compression bands 245 and 246 of the cylindrical outer barrel 260 and the compression collar 226 are used to be crimped down onto the coaxial cable 21 for providing between the connector 220 and the coaxial cable 21. The joint that is safe without causing damage prevents the coaxial cable 21 from coming out of the connector 220. When the coaxial connector 220 is compressed, the connector 220 is placed in a compression tool that grasps the connector 220 and axially compresses the connector from the front and rear ends 223 and 243 along the axis H. 220.

The axial compression force along axis H causes the compression collar 226 to advance along the cylindrical outer barrel 260 in the direction indicated by line I of Figure 8B. The inclined first face 310 of the inner compression band 246 hits the inclined surface 333 of the outer compression band 245 and rotates radially inward, causing the rear end 283 of the cylindrical outer cylinder 260 to collapse radially inwardly. Deformation. The inclined first face 310 slides against the inner surface 251 of the compression collar 226, and the curved portion 305 deforms to enter the shield 340 radially inwardly, causing the circular raised portion 304 to also deform inwardly. When the compression collar 226 is advanced along the cylindrical outer cylinder 260, the curved portion 330 of the outer compression band 245 is in sliding contact with the circular raised portion 304.

When the front end 242 reaches the annular shoulder 313 and abuts the engagement surface 320, the compression collar 226 stops advancing. The engagement surface 320 prevents the compression collar 226 from moving further along the outer sleeve 260, but as the axial compression continues, the compression collar 226 compresses. The axial compressive force along the axis H causes the thin sidewall 276 of the cylindrical outer cylinder 260, the annular sidewall 244, and the compression collar 226 to be squeezed, respectively. The pressure is deformed and bent. The rear end 243 of the compression collar 226 is advanced toward the cylindrical outer barrel 260 such that the compression collar 226 and the outer sleeve 260 are squeezed at the outer and inner compression bands 245 and 246, respectively.

The annular outer compression band 245 is snapped into the V-shaped channel 314 under a sustained axial compression force. The first and second wall portions 325 and 326 are angled inwardly toward the axis H and are joined together. The curved portion 330 is forced radially inwardly into the circular raised portion 304 such that the inner compression band 246 and the annular vertical shoulder 334 are along the radial direction at the rear end 243 of the compression collar 226. It is deformed inward and is fastened and fixed here. The continuous compression cooperates with the inward buckle of the outer compression band 245 to cause the inner compression band 246 to also buckle, as shown in Figure 3B. The rear end 283 of the cylindrical outer barrel 260 contacts and abuts the annular vertical shoulder 334 of the compression collar 226, the rear end 283 being twisted inwardly at the annular vertical shoulder 334 to cause the inner compression band This buckle of 246 is against the circular raised portion 304.

As compression continues, the inner compression band 246 moves into the compressed state to deform the inner compression band 246 into the pawl 360 shown in FIG. 3C. The pawl 360 is a continuous loop and is formed inside the coaxial cable connector 220. The pawl 360 includes an annular lip 361 that faces the front end of the cylindrical outer barrel and a V-shaped passage 362 that faces radially inward toward the axis H. The annular lip 361 rides over the V-shaped channel 362. The outer compression band 245 is closed to eliminate the compression space 331, and the connector 220 is placed in the compressed state. Although the foregoing is a series of steps to demonstrate and illustrate how to move the connector 220 from an uncompressed state to a compressed state, it should be understood that the compression of the connector 220 on the coaxial cable 21 is preferably in a smooth, continuous step. Within, it takes less than 1 second to complete.

In the compressed state of the coaxial cable connector 220, the inner diameter J of the coaxial cable connector 220 becomes the inner diameter J', and the separation distance between the cylindrical outer cylinder 260 and the annular ridges 270a and 270b is now K'. The length of the connector 220 from the front end 223 of the cylindrical outer cylinder 260 to the rear end 243 of the compression collar 220 is M'. The distance K' is smaller than half of the original distance K, and the inner diameter J' is about the original inner diameter J minus the distance K', and the length M' is smaller than the original length M. In a specific embodiment of the connector 220 for the RG6 type coaxial cable, the inner diameter J' is about 6.7 mm, the distance K' is about 0.5 mm, and the length M' is about 18.0 mm. In other embodiments that are used with other types of cables, the dimensions will vary. As shown in FIG. 8C, the diameter of the shield 340 is small, such that the shield 340 of the coaxial cable 21 and the flexible sheath 344 are crimped to the ring of the pawl 360 and the coaxial inner column 261. Between ridges 270a and 270b.

Further, the pawl 360 faces away from the annular ridges 270a and 270b, the V-shaped channel 362 is disposed between the annular ridges 270a and 270b, and the annular lip 361 is behind the annular ridge 270b toward the cylindrical shape. The rear end 243 of the outer cylinder 260, and thus the shield 340 and the flexible sheath 344 are crimped to the pawl 360 and the annular ridge 270a at an axial position between the annular ridges 270a and 270b. The coaxial cable 21 is prevented from coming out of the connector 220 between 270b. The pawl 360 allows the coaxial cable 21 to enter the connector 220 along line 1 in Figure 8C, but prevents the coaxial cable 21 from being pulled away from the wire I. To withdraw the coaxial cable 21, the pawl 360 is deformed radially inwardly and further affixed to the shield 340, the shield 340 and the flexibility The sheath 344 is squeezed and grasped between the pawl 360 and the annular ridges 270a and 270b. Referring again to FIG. 8C, the rigid material properties of the coaxial inner post 261 prevent the coaxial inner post 261 from being damaged by crimping when the connector 220 is attached to the cable 21. In addition, since the dielectric insulator 343 and the inner conductor 230 are protected in the coaxial inner column 261, the flexible sheath 344 is outside the coaxial inner column 261 and the outer surface 265 of the coaxial inner column 261. The contact maintains the continuous connection between the flexible sheath 344 and the coaxial inner column 261, so that the signal transmitted in the connector 220 does not leak out of the connector 220, and the external radio frequency interference The signal also does not leak into the connector 220, which also maintains electrical grounding. The interaction between the flexible sheath 344 and the annular ridges 270a and 270b projecting radially forward and outward from the axis H further prevents the coaxial cable 21 from moving backwards in the direction of the line I. The connector 220 ensures that the connector 220 is securely mounted on the coaxial cable 21.

When the coaxial cable connector 20 is in a compressed state, the connector 20 can be locked to the stud of the optional electrical device in a conventional manner to connect the connector 20 to the electrical device.
