Embodiment
In order to illustrate more clearly of the present invention, the present invention is done further with reference to preferred embodiments and drawings
It is bright.Similar component is indicated with identical reference numeral in attached drawing.It will be appreciated by those skilled in the art that had below
The content of body description is illustrative and be not restrictive, and should not be limited the scope of the invention with this.
A kind of structural section figure in disk rotary joint in the embodiment of the present invention as shown in Figure 1, Fig. 2 show the present invention
The structural section figure that a kind of disk rotary joint is rotated by 90 ° in embodiment.The present invention provides a kind of tool in disk rotary joint
Body embodiment, including boss 1；With reference to the cover board 2 for being fixed on 1 lower surface of boss, the cover board 2 and the boss 1
Form the first cavity；It is enclosed in the housing 3 that the second cavity is formed with the boss 1 of the top of boss 1；And it is arranged on described
The first power splitter in first cavity with line and is arranged on the second power splitter of second cavity with line, first work(point
Device band line and the second power splitter band line have two ports of export；The port of export of first power splitter with line is connected with two
One rod piece 41, the second power splitter band line port of export are connected with two the second rod pieces 42, each first rod piece, 41 He
Connectivity structure is provided between second rod piece 42, which is used for the first rod piece 41 and the electricity of corresponding second rod piece 42
Connection；At least one angle circumferentially of first power splitter with two ports of export of line and the second power splitter with line
Less than 180 degree, those skilled in the art understand, based on this, one of them of the first rod piece 41 and the second rod piece 42 in figure
It should be merely capable of showing a rod piece in the example shown (i.e. Fig. 1 and Fig. 2), i.e. two ports of export when the first power splitter
When at least one angle circumferentially is less than 180 degree, two the first rod pieces 42 are only able to display one, another is in profile
In can not show and (be blocked by boss), understand for convenience, at the same time draw all rod pieces in Fig. 2, it is expressed as corresponding
Rod piece can move to the position, can not represent that all rod pieces can be at the same time on same profile, the present invention is no longer superfluous
State.
Signal is exported to the first rod piece 41, the first rod piece 41 by the first power splitter band line port of export and transmits a signal to gold
Belong to ring 51, becket 51 has coupling regime 53 with metallic channel 52 so that signal can pass through the coupling regime 53 to metallic channel
52, metallic channel 52 is endless metal groove 52, and the lower surface of metallic channel 52 is connected fixation with the second rod piece 42 so that signal leads to
The lower surface for crossing metallic channel 52 is sent to the second rod piece 42, and most signal feeds back to the second power splitter band to the second rod piece 42 at last
Line, the second power splitter band line transmits a signal to the second power splitter, so as to fulfill the first power splitter and the signal of the second power splitter
Connection.
The present invention provides a kind of disk rotary joint, different by the way that feed power splitter is improved to two outlet subtended angles
One-to-two power splitter, greatly reduces the complexity that traditional rotary joint is fed with one point of four power splitter, while also solves rotation
Turn joint during rotation, microwave signal rises and falls the problem of very big.

And the endless metal groove 52 of the becket 51 is accommodated, 52 bottom outer surface of metallic channel and 42 head end of the second rod piece
Tail end top surface, which combines, to be fixed.
In said structure, between the bottom wall inner surface of the metallic channel 52 and the bottom wall surface of the becket 51 with
And it is collectively forming coupling regime 53 between the side wall inner surfaces of the metallic channel 52 and the sidewall surfaces of the becket 51.Should
The thickness of coupling regime 53 is 0.5-1mm, i.e., the bottom wall inner surface of described metallic channel 52 and the bottom wall surface of the becket 51
Distance is 0.5-1mm, and the side wall inner surfaces of the metallic channel 52 and the sidewall surfaces distance of the becket 51 are 0.5-1mm.
Signal can be oriented transmission in coupling regime 53, so that becket 51 is in not contacting metal groove 52
In the case of, signal is quickly transmitted, pass through the matching design of becket 51 and metallic channel 52 so that the first rod piece 41 and
Two rod pieces 42 still can form the connection of signal in the case where that cannot contact, so that this rotary joint can use one
Divide two power splitters, feed becomes simple.
Preferably, as shown in Figure 1, the rotary joint further includes the first supporting item 61 of fixed first rod piece 41,
And the second supporting item 62 of fixed second rod piece 42, first supporting item 61 is fixed with 1 upper surface of boss to be connected
Connect, second supporting item 62 is fixedly connected with 3 inner surface of housing.
Supporting rod is used to support the first rod piece 41 and the second rod piece 42, and the first rod piece 41 and the second rod piece 42 are in supporting rod
Fixation under can keep fixed angle so that in signals transmission, while rotary joint is in the process of rotation
In, the first rod piece 41 and the second rod piece 42 are relatively stable, and microwave signal rises and falls small.
Optionally, as shown in figure 4, two ports of export angle circumferentially of first power splitter with line is 180 degree, then
Two ports of export angle circumferentially of second power splitter with line is less than 180 degree, it is preferable that as shown in Figure 5 described the
Two ports of export angle circumferentially of two power splitters with line is 90 degree.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not pair
The restriction of embodiments of the present invention, for those of ordinary skill in the field, may be used also on the basis of the above description
To make other variations or changes in different ways, all embodiments can not be exhaustive here, it is every to belong to this hair
Row of the obvious changes or variations that bright technical solution is extended out still in protection scope of the present invention.
