Utility model content
The purpose of this utility model is to provide a kind of adjustable cross coupler, to adjust the gap between transmission conductor and coupling conductors, thereby adjusts the degree of coupling of described cavity coupler, and the adjustment operation of described cavity coupler is simple and convenient.
The utility model adopts following technical proposals:
A kind of adjustable cross coupler, it comprises cavity, be arranged on two coupling lines in cavity, be arranged on four ports on cavity wall outer surface, described cavity is circular cylindrical cavity, four ports are separately positioned on the side of circular cylindrical cavity, and the distance between four any two adjacent ports of port all equates; Cavity bottom surface is provided with fixed insulation bar, and two described coupling lines consist of conductor belt and comprise respectively two end portion and a mid portion, and two coupling lines are fixed on fixed insulation bar; Described two coupling lines are respectively about through they mid points on mid portion length direction and symmetrical perpendicular to the symmetry axis of this mid portion separately, mediate the same side of part and tilt and be not in contact with one another towards symmetry axis respectively of two end portion of each coupling line, the madial wall of described circular cylindrical cavity is provided with regulating part, cavity inner bottom surface is provided with insulated support, and described two coupling lines are fixed on insulated support.
Described regulating part comprises nut, screw and insulation head, and described screw is through cavity, and the two ends of described screw are attaching nut and insulation head respectively, and nut is positioned at outside cavity, and conflict wherein of two coupling lines of insulation head.
Two described coupling lines are the first coupling line and the second coupling line, and the two mid portion is mutually opposed and be parallel to each other.
Described four ports are with counterclockwise, according to coupling port, isolated port, straight-through port and input port, are arranged in order.

The utility model is simple in structure, uses column type cavity, easy to assembly, overall appearance; Four mutually perpendicular directions at cavity outer peripheral face arrange respectively four ports, thereby make required coupling line between four ports apart from the shortest, save cost; Further in the side of cavity, the regulating part being comprised of nut, screw and insulation head is set, thereby coupler can be regulated the degree of coupling as required, and need not dismantle, secondary welding is carried out in coupling line gap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of adjustable cross coupler, it comprises cavity 11, be arranged on the first coupling line 3, the second coupling line 2 in cavity 11, be arranged on four ports on cavity 11 sidewall outer surfaces, four ports are to be counterclockwise respectively input port 1, straight-through port 6, isolated port 10 and coupling port 4, thereby coupler volume is minimized, shorten the line distance between port.Four ports are separately positioned on four sides of circular cylindrical cavity 11, and the distance between any two adjacent ports all equates.Two coupling lines consist of conductor belt, and comprise respectively two end portion and a mid portion, mediate the same side of part of two end portion; Two ends of the second coupling line 2 are connected with input port 1 with straight-through port 6 respectively, and two ends of the first coupling line 3 are connected with isolation end 10 with coupled end 4 respectively.
Two coupling lines are respectively about through they mid points on mid portion length direction and symmetrical perpendicular to the symmetry axis of this mid portion separately, mediate the same side of part and tilt and be not in contact with one another towards symmetry axis respectively of two end portion of each coupling line.
Cavity 11 is cylindrical, and the upper cover of not only appearance looks elegant, and cavity 11 and cavity 11 can be realized the (not shown) that is threaded, and coupler sealing is improved greatly, and dismantle easily and fast, install.
Madial wall at circular cylindrical cavity 11 is provided with regulating part, described regulating part comprises nut 7, screw 8 and insulation 9, and screw 8 is through cavity 11, and the two ends of screw 8 are attaching nut 7 and insulation 9 respectively, nut 7 is positioned at outside cavity 11, and insulation 9 conflict are at the mid portion of the first coupling line 3.Column type cavity 11 inner bottom surfaces are provided with 5, two coupling lines of insulated support and are fixed on insulated support.
