Abstract

The utility model discloses a wired remote controller for TV set. One root of special miniature cable whose section is about 3 mm is used by the wired remote controller for TV set to connected a channel preselection switch of the TV set and a power switch with a switch box. So a switch of the switch box corresponds to the switch of the TV set one-to-one, and the purpose of remote control is obtained. The advantages of the utility model are that the original wire connection of the TV set is not changed, only welding on the frequency channels switch printing plate. In addition, the wired remote controller for TV set has the advantages of without debugging, good remote control effect and low cost and is convenient to be popularized in society. In particularly, the utility model is suitable for TV set manufacturers to product and sell as matching components.

Description

Wired remote controller for TV set

The utility model belongs to electronic device, is a kind of wired remote control device of television set.

At present, television set in many families does not possess distant control function, reason is that the television set of production and marketing does not in the past originally have remote control, and the producer of domestic production band remote control television set is also very few until now, thereby a large amount of television sets all suddenly waits to add a remote control to realize distant control function.Two kinds of following remote controls have appearred on the market: as the LK-138 type remote control of import, about 80 yuan of sale prices are also not very too high, but when using with the television set assembling, need to change in the television set five not lead-in wires in the electric tuning loop of easy-to-search, debug difficulties, remote control poor effect; Another kind of device is actually an additional channel transponder, and the program of each channel is converted into a fixed channel, is received by TV set aerial and realizes remote control, and its price height is more than 230 yuan, and volume is big, and the ratio of performance to price is undesirable.So these two kinds of devices all fail to popularize at present.

The utility model proposes simple a, design reliably, and compared with prior art cost is low, remote control is effective, wired remote control device easy to use.

The utility model is that all channel preselection switches of television set and mains switch are guided on the switch enclosure by about 3 a millimeters mini cable of diameter, makes the switch on the switch enclosure corresponding one by one with the switch of television set.Thereby this device is a connector assembly that can be connected with television set, mini cable, switch enclosure composition.Wherein mini cable is a key problem in technology of the present utility model, it is characterized in that including in the plastic sheath layer enamelled wire heart yearn of all kinds and two fluorine 46 high-temperature insulation leads in many thin footpaths.(about 0.21mm) enamelled wire test voltage in thin footpath is more than 1000 volts, allow electric current more than 120 milliamperes, and according to electric tuning loop circuit principle, voltage is not higher than 30 volts on the TV channel preselection switch, the electric current that passes through is not more than 1.5 milliamperes, so the switch that adopts thin footpath enamelled wire to connect channel switch and switch enclosure is suitable fully, safe and reliable; 1500 volts of 0.65 millimeter (heart yearn is 7 * 0.12) test voltages of fluorine 46 high-temperature insulation wire diameters are suitable for 250 volts, 1 ampere of operating state, thereby as 220 volts power control line also be perfectly safe reliable.The heart yearn radical is determined by needs.During as if program that needs eight channels of remote control and mains switch, the heart yearn of mini cable then is made up of above-mentioned 18 enamelled wires and two fluorine 46 high temperature wires.This mini cable serviceability is good, and cross-sectional diameter is little, and is attractive in appearance as the line exquisiteness of wired remote control device.This of particular note this mini cable be applicable to that also other low-voltage, little current field are used.One end of connector assembly---socket connects TV channel switch leads, power control line, the other end---plug connects the mini cable switch enclosure, like this, can insert and to pull out, television set is moved be not subjected to wired the influence, this device gets final product if need only be set up a socket by the employing of television set producer on television set.Not quite household user's connector assembly of mobile television also can be cancelled.Switch enclosure is made up of the number gear switch, and by respectively organizing the enamel-cover core in the mini cable, high temperature wire is connected with each channel switch, mains switch, and the television set spectators can utilize that switch enclosure is opened, the closing television machine, and accent selects the each channel of TV set program.

Technical solution of the present utility model, can be further with following description of drawings it:

Embodiment:

14 cun color television sets of panda brand from February 16th, 89 assembling the utility model so far August surplus, use normal always, drive the switch of television set during use earlier, just can sit and lie in the distant place remote-controlled television set, press the mains switch of switch enclosure, if watch that 6 channel programs are then by corresponding 6 channel switch on the switch enclosure, see that 4 channel programs are promptly by corresponding 4 channel switch on the switch enclosure if change, need if only will sleep by the shutdown of can cutting off the electricity supply of mains switch on the switch enclosure, and the master switch on the television set can be after getting up in second day pass again.That the utility model is watched is effective, volume is little, and the outward appearance dexterity is succinct, easy to use, though be wired remote control, its line footpath is very thin, and the household family be there is no inconvenience.Because cheap (only 30 yuan) are susceptible to user acceptance with regard to present national conditions.

Claims

1, a kind of TV remote-control device is characterized in that comprising:

A, the porous plug seat (1) that is connected with mains switch with the TV channel preselection switch
