Description

Cable TV manual identified electric dual-line switches two groups of many families of signal gating switch enclosures

Affiliated technical field

The present invention relates to a kind of many families common switch box whether cable TV subscriber is paid dues and treat with a certain discrimination, especially allow those hand over the user of expense can enjoy many-sided multi-level service; Though and allow the user of those arrearages cancel many services, but still can guarantee that the cable TV manual identified electric dual-line of watching necessary TV programme switches two groups of many families of signal gating switch enclosures.

Technical background

The development of cable TV and universal, bring unprecedented prosperity to radio and television services, live in mountain area, forest zone and building stand in great numbers the area the resident be difficult to see that the difficult problem of satisfied TV programme has solved, even now also can see colourful TV programme in the subway station, TV has become governments at all levels to propagate the favourable instrument of policy and issue government decree to the people.But owing to many reasons, some subscriber arrearage is serious, makes cable TV network operator pressure very big.People have taked a lot of methods, but owing to reasons such as cable TV signal frequency height, bandwidth, long transmission distance and user's dispersions, not unreliable, destroyed original signal quality exactly, so have to adopt simple and reliable method---the cable of giving defaulting subscriber's input signal is removed.This has not only wasted material, also give and recover to cause difficulty in the future, the more important thing is that these defaulting subscribers have been deprived the policy of governments at all levels and the right to know of government decree, because many television transposer stations closed in succession in recent years, these users also are difficult to obtain better view reception effect by ground transposer station or direct broadcasting satellite, and this new rating blind spot just certainly will occur.In this case, as running into the misfortune dangerous situation, the very first time, who notified them? after the TV signal digitlization, partial programme is carried out the scrambling problem solve.But the first, because the indispensable cover of every television set of descrambling equipment, this is concerning there is the user of several television sets in a family, and license fee is multiplied; The second, in the newly-increased digital receiving equipment, many function general users are usefulness not, wastes, white power consumption; The 3rd, because decryption device is in user family, the network management personnel can't touch at any time, and this " lock " of asking someone to be used for whether allowing the user to watch in the decryption device just for the user privately provides the condition that makes things convenient for; The 4th, the user for basic charge is not also handed over steals signal in order to prevent it, and last solution is still the cable of the input signal of removing this user, has got back to so again on the digitlization old road in the past.

Summary of the invention

In order to move on to the place that the network management personnel touches at any time from user family being used for controlling " lock " whether the user allow to receive the paying signal, and allow the people who has paid each level of the user whole family that takes to enjoy colourful TV programme, and save meaningless expense and power consumption; Unpaid user also can watch free clearly TV programme simultaneously, if hand in retroactively after the expense, can also recover to comprise whole signals of paying signal easily; Cable TV manual identified of the present invention is electronic two

The technical solution adopted for the present invention to solve the technical problems is: switch in two groups of many families of signal gating switch enclosures at cable TV manual identified electric dual-line, divide upper, middle and lower three cabins; In upper-deck cabin (31), rotatablely move by DC motor (19) generation, after multistage spur gear slows down, pass to middle deck (Z) by main shaft; In middle deck (Z), the nut of movement arm is worn on the screw rod of main shaft, movement arm is moved under the drive of main shaft: when main shaft from the upper-deck cabin direction, looking to middle deck is when being rotated counterclockwise, movement arm also is rotated counterclockwise, and the spring leaf (35) that is fixed on the pivoted window bottom also rotates thereupon, when spring leaf forwards a certain position to and supresses action orientation switch (15), amber light (14) has been connected DC power supply (11) and has been lighted, thereby learns the top of movement arm at which soft rod (28); Because the in addition position-sensing switch (17) arranged side by side with orientation switch (15) position, position-sensing switch (17) not only is connected between DC motor (19) and the DC power supply (11), but also be in parallel with change status switch (18) circuit, just when changing status switch (18) when being in release condition, position-sensing switch (17) is by short circuit, spring leaf (35) is by not rotating not according to do not influence DC motor (19) to it, but when changing status switch (18) when pressing down, because position-sensing switch this moment (17) has been cancelled short-channel, at this moment when spring leaf (35) is pressed position-sensing switch (17) again, just cut off the power supply of DC motor (19) immediately, make it to stop operating immediately; This moment pivoted window window just facing to A to breach, that is to say that movement arm is just pressing down the top that changes the corresponding soft rod (28) of status switch (18); Because ratchet (36) is arranged at the bottom of pivoted window, under the effect of spring ratchet (40), pivoted window can only be rotated counterclockwise; When main shaft turns clockwise, pivoted window is as you were, force movement arm under the effect of main shaft spiral shell button, can only move downward along the window of pivoted window, oppressing soft rod (28) also moves downward, and compression big spring (29), be stressed and move up to limit switch (16), cut off till the DC power supply (11) of DC motor (19): the polarity of conversion DC power supply at this moment (11), make DC motor (19) counter-rotating, main shaft rotates counterclockwise again, thus the time movement arm still A to breach in, can not rotate counterclockwise, can only move upward up to breaking away from A fully till breach to breach along A; And the soft rod (28) that is depressed has broken away from the pole cap, under the effect of big spring (29) bounce that has been compressed, has also returned to original position fully; In following cabin (X), at first, aspect TV signal,, behind splitter (3), be divided into two-way the full signal of sending here from network that contains free signal and paying signal, this two paths of signals is taked to be fixed on down in the cabin (X) after the shielding separately; One the tunnel directly behind first distributor, delivers on the cable plug (6) with cable (9); Another road filters the signal that must pay behind band pass filter (5), with no damage free signal is delivered to another cable plug (6) through second distributor again; These two cable plugs are each corresponding cable socket (7) all, and these two cable sockets (7) are all direct and signal output bolt receptacles (8) links, these three sockets are formed three sockets of " Y " font structure, no matter two cable sockets (7) which have the signal input, signal output bolt receptacles (8) all has signal output; Secondly, in mechanical aspects, above-mentioned two cable plugs (6), all be fixed on the lower end of a teeth pole (24) separately, and being engaged in the both sides of a control gear (32) between these two teeth poles (24) simultaneously, this has just determined, when a teeth pole (24) descends, another teeth pole (24) rises certainly, forms the alternative structure; The 3rd, in order to ensure each soft rod (28) cable plug (6) of original discord cable socket (7) contact is inserted, simultaneously the cable plug of having inserted in cable socket (7) originally (6) is pulled out, all fix a pole cap in the upper end of two teeth poles (24), when the teeth pole is raised to the extreme higher position, at pole gap and bumping under the effect of pearl (34), tiltable slideway (26) will guarantee that each soft rod (28) is all accurately by to that the highest teeth pole (24), certainly just originally originally being that plugs and sockets separately is inserted into together, and a plugs and sockets that originally has been plugged together separately.

The invention has the beneficial effects as follows: switch in two groups of many families of signal gating switch enclosures at cable TV manual identified electric dual-line, at first owing to the cable plug (6) and the cable socket (7) that are used for the TV signal two-wire is switched, extensive use in the TV signal switching at present, they not only contact, and high frequency performance, can not cause any damage and interference to video quality; Though other switches in this box are many, portion does not directly contact with TV signal, only keeps operating state at ordinary times, and no power can not cause any interference to TV signal yet; The 3rd, the present invention just just plugs external switch (WK) temporarily in the needs inspection or when switching the user side accepting state, at ordinary times need not any power source; The 4th, the present invention is that many families are shared, and need not therefore can reduce expense significantly to the program scrambling descrambling; The 5th, the present invention is in outdoor mounted, and the network management personnel can be checked or change at any time, and weatherproof except that water proof and dust proof, is adapted at China various places and uses; The 6th, as long as paid expense, several TVs of the whole family can be watched simultaneously.

Embodiment

Cable TV manual identified electric dual-line of the present invention switches two groups of many families of signal gating switch enclosures, at ordinary times need not any power source, only when checking or switch certain family accepting state, just open the dustproof and waterproof lid (38) that connects male connector socket (20) temporarily, insert the external switch (WK) that has DC power supply (11).At this moment energized master switch (12) can see that all users' signal output bolt receptacles (8) side all has a lampet bright.Green light (1) is bright, illustrate that this user exports the cable plug of composite video signal (6) and inserted cable socket (7), this family contains free signal at interior pay TV signal in reception, because its cable extraction tube (23) compressing User Status switch (13) just makes green light (1) bright; If red light (4) is bright, illustrate that this user is just receiving free TV signal (reason is the same).Where bright amber light (14) is, just shows movement arm this moment in the box is with regard to where.If want to switch the accepting state at certain family, the first step is pressed the change status switch (18) at this family so; Second step, press step switch (22), DC motor (19) is rotated, after slowing down, the rotation of drive spindle axis counterclockwise, also drive simultaneously movement arm, pivoted window and spring leaf (35) also are rotated counterclockwise, spring leaf (35) is pressed action orientation switch (15) on the way, inform people's movement arm position by amber light (14), and position-sensing switch (17) is though also there is action, but because of there being change status switch (18) with it in parallel to be in on-state, so it is inoperative, but when spring leaf (35) by when pressing the position-sensing switch (17) of change status switch (18), no longer including the paralleling switch that is in on-state exists, along with the disconnection of position-sensing switch (17), DC motor (18) stops operating, certainly main shaft, movement arm and pivoted window also stop operating.At this moment the lamp that shows each family accepting state, always green or red should have one bright, and amber light has one only, the amber light (14) that is exactly corresponding change state user is bright.This shows that switching this user's accepting state work can begin.The 3rd step, press phase-change switch (21), still press step switch (22), at this moment DC motor (19) restarts, but turns to original opposite, cause main shaft to turn clockwise, but pivoted window has the effect of ratchet (36) and spring ratchet (40) in the bottom, can not turn clockwise, but main shaft is also turning clockwise, under the effect of spiral shell button, movement arm can only move downward along the window of pivoted window.Movement arm stretches out that part of of pivoted window window simultaneously, just A that needs switch the user to breach above, movement arm moves downward and forces soft rod (28) also to move downward, compress big spring (29) simultaneously, soft rod stretches out middle deck (Z) and continues motion in cabin (X) downwards, runs into tiltable slideway (26) change direction directly by in the nest of pole cap.Along with DC motor (19) is constantly rotated, main shaft is also constantly exerted pressure to movement arm, causes the pole cap pressing teeth pole (24) constantly moving downwards, forces control gear (32) to rotate, and the teeth pole (24) that has also driven opposite side moves upward; And gradually the cable plug that was inserted in cable socket (7) originally (6) is extracted; Along with DC motor (19) is constantly rotated, by soft rod (28) according to teeth pole (24) also constantly move downward, cable plug (6) fixing below it inserts in the cable socket (7) fully, at this moment just cable extraction tube (23) pressure has been led to User Status switch (13), has connected relevant lamp; Movement arm has just disconnected limit switch (16) again to pressing down subsequently, has cut off the power supply of DC motor (19), makes it to stop operating, and main shaft, movement arm be all stop motions also; The teeth pole (24) of opposite side, in said process, under the effect of control wheel (32), also constantly rise, not only cable plug (6) has been pulled out from cable socket (7), but also discharged the original User Status switch (13) that is led to by pressure, and its corresponding lamp has also been gone out, continue to rise and tiltable slideway (26) is pushed up in the gap of pole cap, accept the action of soft rod (28) when forming maximum inclination angle wait action next time up to bumping pearl (34); The 4th step, discharge phase-change switch (21), still press step switch (22), at this moment DC motor (19) restarts, and makes spindle axis counterclockwise rotation, but since movement arm stretch out that part of still A to breach in, can not rotate counterclockwise, under the effect of main shaft spiral shell button, can only along A to breach move upward, till the upper side frame that comes out completely and push up rotary window, just can be with pivoted window to go to have sought next user side; And soft rod (28) returns to the origin-location under the effect of the bounce of compressed big spring (29).At this moment discharge change status switch (18), powered-down master switch (12) is extracted external plug, and the dustproof and waterproof lid of tightening external plug (20) gets final product.

This operation of tool at ordinary times: if check that just as long as plug external plug, the opening power master switch is promptly known at a glance; If must switch certain family, the first step is pressed this family and is changed status switch (18); In second step, press step switch (22); The 3rd step, by the time to amber light (14) that should the family bright after, press phase-change switch (21); In the 4th step, after this family traffic lights exchange by the time is bright, discharge phase-change switch (21); In the 5th step, it is bright to wait until that other family amber lights (14) also begin, with regard to release movement switch (22).
