In the figure, 1-cavity, 2-joint, 3-strip line, 4-I-shaped insulator, 5-resistor, 6-inner cover plate, 7-outer cover plate, 8-screw, 9-sealing ring and 10-positioning hole.
Detailed Description
The present invention will be described in detail with reference to the following embodiments and drawings.
Example (b): the small broadband air strip line Wilkinson power divider is mainly characterized in that the insulator is an I-shaped insulator 4, a positioning hole 10 is arranged in the cavity 1, the strip line 3 provided with the I-shaped insulator 4 is placed in the positioning hole 10, the strip line 3 and the cavity 1 are fixed through the I-shaped insulator 4, the resistor 5 is welded on the strip line 3 in a hanging mode, and the connector 2 is connected with the cavity 1 in a pressing mode.
In the embodiment, an air bag step is arranged inside the cavity 1; the apron adopts interior outer apron mode, and interior apron 6 and cavity 1 fastening contact, and outer apron 7 passes through sealing washer 9 and cavity 1 fastening, and interior outer apron passes through screw 8 and cavity 1 fastening.
In the embodiment, a strip line 3 is placed in the cavity 1 and is placed in a positioning hole of the cavity 1 in a welding mode. The connectors 2 are tightly pressed with the cavity 1 through screws 8, and the number of the connectors 2 is three in the embodiment.
The present embodiment is assembled as follows: the connector 2 is tightly pressed into the cavity 1, the connector 2 is fastened through a screw 8, the I-shaped insulator 4 is clamped on the strip line 3 and is correspondingly placed in a positioning hole 10 in the cavity 1, the strip line 3 and the I-shaped insulator 4 are sequentially placed into the cavity 1 through tools and welded, the resistor 5 is welded on the strip line 3 in a suspended mode, an inner cavity is cleaned, the inner cover plate 6 is fastened with the cavity 1 through the screw 8, the sealing ring 9 is placed, and finally the outer cover plate 7 is fastened with the cavity 1.
The utility model is used in an indoor distribution system, because the realization mode is a strip line 3 structure, the strip line 3 is made of metal plates, the joint 2 is tightly pressed into the cavity 1, and the inner cover plate 6 is used to be contacted and fastened with the cavity 1 independently, the conventional performance and the three-order intermodulation (which can reach-150 dBc generally and can reach-160 dBc when the requirement is higher) are improved; the strip line 3 is fixed by the I-shaped insulator 4 and is correspondingly placed in the positioning hole in the cavity 1, so that the mechanical stability (drop resistance, vibration resistance, collision resistance and the like) of the strip line Wilkinson power divider is improved; the sealing ring 9 and the outer cover plate 7 are fastened with the cavity 1, so that the sealing performance and the attractiveness are ensured.
The upper left corner in fig. 1 shows the mutual assembly and connection state of the cavity 1, the strip line 3, the i-shaped insulator 4, the resistor 5 and the connector 2 after the inner cover plate 6 and the outer cover plate 7 are taken away, and the lower right corner is the situation of covering the inner cover plate and the outer cover plate.
