Abstract

A connector adapted for a cavity filter of the present invention includes a contact pin, a first insulator, a housing and a transmission line, the first insulator is provided with a first locating hole, the housing shaped as a cylinder is provided with a second locating hole. During the assembly, no additional mounting slot is required. Less space is taken up by the cylindrical housing, which provides more space for the transmission line and makes the line connections easier therefore. Moreover, the assembly of the connector is simple and efficient, and the connector is in an integrated structure, and the components of the connector are connected by inserting or plugging, which reduces the welding points, thus the vibrations among the components are reduced and the accumulated assembly tolerances are reduced accordingly, thereby the communication quality is improved and the cost is decreased.

First claim

What is claimed is:

1. A connector adapted for a cavity filter, comprising a contact pin, a first insulator, a housing and a transmission line, wherein the first insulator is provided with a first locating hole, the housing shaped as a cylinder is provided with a second locating hole, the contact pin is inserted into the first and the second locating hole in turn, the first insulator is received in the second locating hole, an upper end of the contact pin is located outside the housing, and the transmission line has a first end inserted into the second locating hole and connected with a lower end of the contact pin and a second end connected with a resonance tube of the cavity filter;
the housing comprises a first housing portion, a second housing portion and a cover, both of the first and the second housing portions are cylindrical, the second housing portion is sleeved on the first housing portion, and second housing portion is sealed by the cover; the first housing portion comprises a first cylindrical body and a second cylindrical body that are vertical and communicated with one another, the second housing portion comprises a third cylindrical body that is vertical and a fourth cylindrical body that is horizontal and communicated with the third cylindrical body, an inner diameter of the first cylindrical body is larger than that of the third cylindrical body, and the third cylindrical body is sleeved on the second cylindrical body.

2. The connector adapted for a cavity filter according to claim 1 , further comprising a gasket ring, wherein the first housing portion comprises an annular groove in which the gasket ring is received.
