Moving part coaxial connectors

[0001] The invention link to manufactured products. In particular, the coaxial cable connector includes a movable nose. Discussing the Related Art [0002] In cable and satellite (CATV) systems, the signaling radio signals ("RFs") are exchanged at the coaxial connectors of cables. Other Among other Among signal Among Among Among Among Among Among Among Among Among Among Among.

[0003] Efforts have been described to far distortive RF signals in CATV systems, including the experimental inventor. The solutions has been extended to the traditional shielding of connectors, multi-pass coaxial cables, and high-pass filters limiting low frequency signals and interfaces with active home CATV systems.

[...] F connectors ("F"). connectors).

[0005] In the inventor's opinion, the poor signal transport through matched connectors, and the open source are potential problems.

[0006] Stray RF signals can cause problems in CATV systems, such as, for example, home CATV systems. For example, when the subscriber leaves a CATV connection, such as a cable connector in the disconnected / open state, an unprotected entry. Open RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF.

[0007] F-type connectors are widely used in the United States for connecting cable and satellite television equipment. Wall-mounted F-type female connectors and / or a coaxial "attachment" cable containing a male modem. In particular, female F-type female connectors are connected via a coaxial cable terminated with male connectors at opposite ends.

[0008] Regardless of whether a CATV signal is attached to a potential source of unwanted RF signals. Wall-mounted connectors left open or coaxial cables attached to a wall-mounted connector, but otherwise open. Connecting cables, for example ended with a male. F-type connector, when left open, become an RF signal.

[0009] Numerous CATV connections at the end of the process of generating RF unwanted signals. And when subscribers leave homes, CATV connectors are usually left. RF signal in a CATV distribution system.

[0010] A known method for eliminating the unwanted RF input in a CATV system is the use of a terminal unplugged on a power socket F in the home network box. But in the typical case, home CATV signal is in a CATV signal.

[0011] The inventor of the current generation of RFIDs. Therefore, to the extent that the CATV industry recognizes the need to further reduce RF interference to CATV systems, it is desirable to have connectors that reduce unwanted RF signals are left open.

[0012] The undesired RF signal transfer points are formed by loosely fitting connectors. In particular, loose connectors typically have gaps in the electromagnetic shield for the transmission of the signal. These gaps also interrupt the ground path circuits. In this case, the penetrating signals, the loose fit of the nut. In particular, in some recent female type F joints, problem F F F F F F F F F F F F F F. (Look, for example, patents US 6 712 631, 6 716 062 and 7 753 705). Some others use a spring located behind the male connector. One solution (ie 6 712 631) uses a spring washer as a spring to alleviate the problem. See also EP-A1-1 895 625.

[0013] In particular, although the signal penetration is a F-type female connector. Furthermore, known solutions do not solve the undesirable problem. RF signal transfer via loose nut threads.

[0014] The inventor of the type of connector F connector describing and releating on the female connector. In addition, although movable part activators have switch and bypass clamps, these devices are not dissimilar to the present invention.

[0015] A signal barrier interference in the RF barrier. In other words, CATV service providers.

[0016] Some references use movable insulators. However, these are the differences between the present invention and the central heating system. For example, patents US 4 660 921 and 5 598 132 use a movable central pin attached to a movable insulator. Central contact central contact with contact with contact with central central central. Central assistant. In particular, installers manually stretch sections of the central coaxial cable, and when they are too short, they do not come into contact with the moving central pin.

[0017] The patent US 6 270 367 requires a central conduit to form a spring coil. As is well-known, 20 ن ,رة ال will willرة, Gigahertz requirements.

[0018] The patent US 6 329 251 discloses a central joint conduit as a working component when transferring forces. This construction impairs the conductive central pin of the connector and impairs

[0019] The patent US 7 938 680 ("680" patent) includes a directed body in a tube protruding from the front. portion of the cap core. In the '680 patent, solving the problem of the internal connection is located. This would be a result of contact with the outer sleeve. However, this approach also has disadvantages. For example, there is a need for an inexpensive, very large outer nut with a new inner sleeve. also,

[0020] The boundary surface between the male and female concentric needs to communicate with the RF in the coherence and to prevent the transmission of undesired signals. These goals are supported in many different ways with concentric RF connectors. One method used on BNC connectors is the spring loaded earthing elements on the male and female connectors. Another method uses threaded male and female boundary surfaces and precise crimp specifications to ensure proper operation. Industrial experience shows that it is necessary for a high level of environmental protection, as well as high temperature changes. however, F-type coaxial connectors are difficult to install. Therefore, there is a need for the loose male connector.

[0021] The male F-type concentric connectors is an internally threaded connector. In various examples, tight-fitting connectors retain a good connection to the external earthing. However, if the male nut is not completely clamped to the female connector. Known methods for solving the problem of the loose union nut Solutions for this cable has an off-axis system,

In some embodiments, the movable nose includes a through hole 853 for a telescopic arrangement with a socket base. The movable nose protrudes from the opening 809 of the end face of the body. The channels in the socket base 842 and the movable nose 832, 882 serve to receive a central coaxial cable. As shown, the channels form access to the conductive pin 820, which is approximately centrally located in the body selected. The first end of the conductive pin 891 is the seat of the opposite, 893 897 of the nose 806, 856. In various embodiments, the other end of the conductive pin is not supported by the moveable nose. Furthermore, in various ways, the other end of the conductive pin is cantilever (as shown).

[0083] Fig. 8A shows a movable nose 806 with a magnetically non-shielding nose pad base 826 disposed in an electromagnetically shielding nose cap, eg a metal cap cap 816. When moving the vat with the nose, the nose cap shields the adjacent end 893 of the movable nip of terminal 809.

[0084] Fig. 8B shows a movable nose 856 with an electromagnetically shielding nose portion 836 in a portion of the nose. In different situations, the nose portion may be subjected to a magnetic shielding. The treatment may include the treatment of coatings, coatings and inserts. The treatment may also be made of magnetically shielding elements. For example, the particulate metal (e) may be suspended with a desired shielding properties.
