Description
[technical field]
The invention belongs to a kind of slip ring, be specifically related to a kind of can satisfy transmit the slip ring of the digital high-definition signal of 1080P at least.
[background technology]
We then are referred to as high definition to the form that physical resolution reaches more than the 720p usually, and English statement High Definition is called for short HD.So-called full HD (Full HD) is meant that physical resolution lines by line scan up to 1920 * 1080, i.e. 1080p high definition is a top high definition specification at present.Digital high-definition is different with the traditional tv system of current employing analog signal transmission.Owing to the collection of its signal, be fabricated into transmission; And all realize digitlization to the reception of user terminal, so the digital signal receiving terminal can bring high definition to us, resolution reaches as high as 1920 * 1080; Frame per second is enough to let present DVD blushing with shame up to 60fps.In addition, the reception signal terminal screen width high ratio has also become 16: 9 by original 4: 3, if use large scale display that the sensation of coming to movie theatre personally is then arranged.Owing to used digital technology, the signal anti-noise ability is also strengthened greatly simultaneously, and on audio system, it supports Doby 5.1 sound channels to transmit, and brings people Hi-Fi level other hearing enjoying.Compare with simulated television; DTV has high definition picture, clear stereo sound accompaniment, TV signal can be stored, can accomplish multiple advantages such as multimedia system, frequency resource utilization be abundant with computer, and many particularly full HD digital technologies of advantage digital high-definition technology will become the main flow in this field.
The digital high-definition signal is in transmission course, and particularly signals collecting end such as traffic security protection probe is because its operating characteristic needs rotation, so in the signal transmission, adopt slip ring to connect signal transmission line and probe.The signal of generally gathering of prior art is lower than the analog signal of 720P, and the digital signal of 720P is perhaps only arranged, and the slip ring of prior art can satisfy basically between its probe and the signal transmission line and is connected.But along with the development 1080P of high definition technology and even be higher than full HD signals collecting and the reception technique maturation of the digital signal of 1080P; And existing slip ring can't satisfy 1080P or above high-definition digital signal transmission; Signal can postpone in signals transmission, voice are asynchronous, data-signal is lost, and the high definition data signal terminals that causes collecting can't obtain.Be applied in optical fiber technology on the connection line of slip ring and in fact also can satisfy 1080P or above digital data transmission, but, increase the production cost of digital high-definition slip ring greatly, be unfavorable for it and apply because it costs an arm and a leg.
[summary of the invention]
For solving above deficiency; The present invention provides a kind of digital high-definition slip ring through 1080P; This slip ring can satisfy the digital high-definition signal transmission that is not less than 1080P, and its production cost is lower simultaneously, reduces more than 80% than the digital high-definition slip ring cost that adopts optical fiber technology.
The technical problem that the present invention will solve is: the digital high-definition signal that needs the 1080P more than the 720P along with technical development and some special dimension; And existing slip ring can only connect digital signal or analog signal that transmission is not higher than 720P; In slip ring, can satisfy above requirement through fiber optic applications; But because it costs an arm and a leg, directly cause high-definition digital slip ring production cost to improve greatly, be unfavorable for that the high-definition digital slip ring is in the civil area promotion and application.
The technical scheme that the present invention adopted is: a kind of digital high-definition slip ring through 1080P; It is characterized in that comprising in the shell stator and rotor; Rotor surface has several conducting rings; One end of the fixing some precious metal electric brush silks of the corresponding conducting ring of stator, other end of precious metal electric brush silk and conducting ring slip, and rotor limits its Device for elimination of axial-and radial-play through some bearings; One sleeve pipe is arranged in the rotor, and cable inserts the sleeve pipe cable through the coaxial cable cover and connects jack, and reed is inserted in shell, and MMCX-K joint (coaxial radio-frequency joint) is socketed in the reed, and the MMCX-K joint connects a contact pin.
Described a kind of digital high-definition slip ring through 1080P, it is characterized in that described contact pin insert jack and with the sliding contact of jack inwall.
The present invention can be connected in such as be used for the probe of traffic; Because its operating characteristic needs to rotate up and down; Slip ring is applied in probe and is connected with circuit; Control circuit is because it not as the requirement of digital high-definition signal to circuit, connects stator through an end, and the common line that an other end connects rotor can satisfy the supply of power supply and the transmission of control signal.And because in order to realize the purpose of digital high-definition; Take acquisition high-definition digital signal through probe and comprise that sound and picture signal form synchronously; The high-definition digital signal is through the contact pin and the jack that is connected the cable that satisfies the high-definition digital signal of MMCX-K joint then, contact transmission digital high-definition signal through rotating between jack and contact pin.The slip ring that the present invention has overcome prior art can't satisfy the high-definition digital signal obstacle that is higher than 720P, loss of data, voice can not occur in the signal transmission and picture signal is asynchronous or image card frame phenomenon, and contact pin adopts precious metal material can satisfy 500,000 commentaries on classics.
Beneficial effect of the present invention: the present invention realizes that the 1080P of slip ring or above high-definition digital signal rotation connect, simultaneously the very big production cost that reduced simple in structure.
Further understand characteristic of the present invention and technology contents for making, see accompanying drawing of the present invention and execution mode for details, yet appended graphic only for reference and explanation usefulness is not to be that the present invention is limited.
