Description

Delay compensated jack

The present invention relates to socket assembly.More precisely, the present invention relates to the socket assembly that video signal transmission is used, on this occasion, this socket assembly comprises delay compensation component.

In relevant " most preferred embodiment specification " part of the application's book, in conjunction with the accompanying drawings more detailed description is proposed prior art.But, for the purpose of explanation, will brief description be proposed to prior art and applicable environment of the present invention below.

The present invention's expection is used for the transmission of colour-video signal.In the color video transmission, the timing relationship of different colour signals limits the ability that chooses at random any given circuit, promptly uses by video route indicator cock and selects those circuit.If the timing relationship between those circuit is incorrect, the tone of different video signal just need be recalibrated it when this signal is selected each other also with incorrect.This recalibration is not only unrealistic but also inconvenient.

When television stadio begins to set up broadcasting, but needn't recalibrate in order to ensure any signal in selected these signals of mat route indicator cock, must calibrate used various video transmission equipment, so that between whole circuit that all are equipped with the route indicator cock is connected, keep a correct timing relationship.One of greatest factor that influences this timing relationship be every device with routing switch between the length of coaxial vision cable.In given circuit, any variation of coaxial vision cable length aspect will influence the relevant timing relationship of other circuit in these Circuits and Systems.

And in broadcasting is carried out, tend to require TV signal between the different units of broadcasting equipment, to change route.For example, when initial foundation, broadcasting equipment may use the route indicator cock that the signal from TV camera is connected to certain television recording equipment.During broadcasting,, just need decide route to signal again and link another video equipment if when this television recording equipment has problems.

Route for facility change vision signal has connected video jackfield at different equipment rooms.Yet, during broadcasting as when the change of any signal route takes place, must keep the timing relationship of described equipment.

The change of two equipment room TV signal routes means that signal becomes absonant and causes a kind of possibility of tonal distortion during broadcasting.This possibility is attributable to the stube cable that is used in combination with video jackfield.A stube cable only is a cable of two ends band plug.For deciding route again for signal, a plug of stube cable is inserted with the socket of input signal, and its second plug insertion is connected in the socket of second equipment, described signal is prepared to decide route again and is pointed to this second equipment.Therefore, during changing route, the given length (that is the length of stube cable) of cable added effectively receive in the good broadcasting equipment system of predetermined calibration.If do not give consideration, then this cable length that adds can cause infringement calibration and tonal distortion.

The video jackfield sub-assembly that can buy on the current market uses the cable with the stube cable equal in length to be added on the video jackfield sub-assembly self.An example of this product by the U.S., the Minnesota State, Minneapolis, ADC Telecommunication (assignee of the present invention) with " Video Pro Patch MKII ^TM" trade mark sells.The example of this product was shown on the 24th and 25 page in the brochure that is entitled as " special-purpose audio frequency and video product " that in April, 1988, Adc Inc. published.

At " Video Pro Patch MKII ^TM" in, jack circuit or socket assembly are made up of two sockets.The first socket received signal, and second socket connects signal to desired video transmission equipment.Be connected two sockets with a cable (being referred to as to compensate loop line) with the stube cable equal in length of preparing to be used for this female receptacle.For example, described " Video Pro Patch MKII ^TM" currently comprising three feet long compensation loop lines, this loop line requires female receptacle with three feet long stube cables.If need four feet long stube cables, then compensating loop line will need four feet length.The ADC publication is pointed as described above, illustrates that the inefficacy of three feet length stube cables can cause six degree phase shifts.

Although resemble " Video Pro Patch MKII ^TM" such prior art phase place or delay compensation female receptacle is acceptable aspect functional, but also there is some shortcoming in they.For example, each socket assembly that connects with three feet long coaxial cables needs two sockets, causes female receptacle heavy and expensive.Therefore, though the delay compensation female receptacle of this prior art has the acceptability on the function, but still the lasting video jackfield that needs a kind of improvement.

Provide a kind of compensation socket according to most preferred embodiment of the present invention, this kind compensation socket comprises first, second and the 3rd port, is respectively applied for to connect first, second and triaxial cable.First signalling channel is provided within socket, when being connected respectively to first and second ports, is used to be electrically connected first and second cables.The secondary signal passage is provided within socket, when cable being connected respectively to the first and the 3rd port, is used for first cable is connected to the 3rd cable.This first signalling channel comprises selected circuit element of deriving a predetermined backoff signal, and this compensating signal becomes the signal by first passage.One switching mechanism is provided, when the 3rd cable is connected to the 3rd port, is used to disconnect first passage.

Before point out that delay circuit 62 comprises the combination of

spring conductor

64,66 and circuit element 68.This circuit element is commonly referred to as delay line, for example can be to be arranged in the series of products of the ESC electronics corporation of New Jersey, GAP PARK (Palisades Park) in their brochure " delay line and transformer " listed being masked as " ST ".

Circuit element 68 is chosen to be and will produces a delay to the signal by this circuit element.The retardation of selecting circuit element 68 is used for simulating the length of a coaxial cable, makes it to equal the length that predetermined preparation is used for the stube cable of this socket.For example, with three feet long stube cable logotypes, the delay that preferably selected circuit element 68 gives equals signal by three feet a period of times that long stube cable is required concerning expection.This approximately is 5.5 nanoseconds.For four feet long stube cables, current expection preferably postpones to be about 7.3 nanoseconds, and circuit element just should so come to select.To point out that below the circuit element that picture dot spare 68 is such can be buied on the market.For example the small-sized signal delay line products of the ST of ESC electronics corporation series does not form part of the present invention in essence.

Have under the structure situation of the present invention as mentioned above, available socket 40 replaces the socket assembly of prior art to be used for the cross-over connection video equipment, and this socket can three kinds of pattern work.In first kind of mode of operation, socket does not insert cable as shown in Figure 5.When not inserting cable, no signal changes route, and at this moment the dotted line E with Fig. 5 shows the signal route.TV signal enters rear port 52 and passes through first signal path (port 52 leads to contact D to contact C by circuit element 68, leads to port 53 again).

(single stube cable mode of operation) inserted plug in

port

46 or 48 in second kind of mode of operation.Insert port 46 as example with a plug, delay circuit 62 gives ground connection via switching mechanism 156 and resistance 84.Signal directly leads to the socket plug 61 of inserting port 46 from connector by conductor 150.F illustrates this route as Figure 10 center line.

Except that above-mentioned, socket also can be used for dual link cable mode of operation, at this moment two plugs is inserted in the two-port 46 and 48.In this embodiment, signal directly leads to port 46 from plug 52.Similarly, an input signal entry port 48 backs directly lead to port 53.

Under structure of the present invention and mode of operation situation as mentioned above, the advantage that the present invention surpasses prior art is very clear and definite.The socket assembly of prior art needs two sockets, and this two socket is linked to each other by one section middle loop line that is generally three feet long.Structure of the present invention is improved, thereby whole socket assembly now can not formed with the socket of middle loop line by one.Simple observation by Fig. 3 and Fig. 5 just can be seen these benefits.With total length (that is, from front port 50,50 ' to rear port 26,26 ' size) shorten greatly.Equally, Zhong Jian compensation loop line (being generally three feet long) has given omission.In addition, two sockets replace with the unitary socket body.Design advantage of the present invention is saving of labor, reduction material cost and the part dimension that dwindles each circuit greatly.Owing in each jack, comprise numerous socket assembly, therefore greatly reduce needed total cost of whole female receptacle and actual size.

According to the front detailed description of the present invention, various purpose of the present invention has been shown how has been achieved by best mode.But, will comprise within the scope of the invention all that in modification aspect the disclosed notion and coordinate this is to being easy to expect such as those skilled in the art.Therefore, scope of the present invention is only limited by the scope of following subsidiary claims.
