Abstract

The present invention provides a remote radio device, a duplexer, a filter and a tap fixing member. The tap fixing member is used for fixing a tap having an insertion part, the tap fixing member comprises a columnar body, one end of the columnar body is provided with a groove running through the columnar body in the radial direction, the bottom of the groove is provided with a hole, and a flange is arranged on the outer side wall of the end of the columnar body provided with the groove; the insertion part of the tap is inserted in the hole, and the insertion part of the tap is tightly fitted into the hole, and the flange of the columnar body is pressed and deformed to cause the inner wall of the groove to clamp the tap. The tap fixing member is simple in processing, and the tap or the tap fixing member is easy and convenient to assemble and is steady, thereby ensuring stable signal index of the filter.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a radio frequency remote device, a duplexer, a filter and a tap fixing part. Background technique [0002] The tap piece is connected between the resonator of the filter and the connector for signal transmission. The prior art device for fixing the tap piece is such as figure 1 As shown, the fixing device includes a cylindrical clamping seat 1 and a square fixing seat 2. The middle part of the cylindrical clamping seat 1 has a square groove 4 for accommodating the tapping piece 3. The square groove 4 has a clear corner feature 5, and the clamping seat 1 The end has a thin groove 6 communicating with the square groove. The square fixing seat 2 has a square groove and a round hole 8 for accommodating the clamping seat 1. When the tap piece 3 is installed, the tap piece 3 passes through the thin groove 6 and abuts to the square groove 4. Then assemble the cylindrical clamp...
