Description

Connector for antennas {A connector for antenna}

The present invention relates to an antenna connector for enhanced coupling force, and more particularly, to a base station antenna installed to be exposed to an external environment. The coupling force is changed so that moisture does not penetrate into the connector by changing the coupling structure between the connectors. The present invention relates to a reinforced antenna connector.

In general, a connector for a base station antenna is largely coupled to a first connector mounted on an antenna and a second connector mounted on a power feeding cable by a circular coupling protrusion and a corresponding coupling groove. When the connector is not in close contact with the antenna and the coupling force between the first connector and the second connector is dropped and exposed to the external environment, moisture may penetrate into the connector due to rain, which may adversely affect the system. It became.

1 is a cross-sectional view showing a fastening state of a connector according to the prior art, wherein the connector has a first connector outer conductor 10 having one end coupled to the antenna 3 and a coupling groove formed at the other end. Connector 1 and a cable is connected to one end and the other end having a second connector outer conductor 20 formed with a coupling protrusion for coupling with the first connector outer conductor 10 of the first connector (1) It consists of a second connector (2), the shrinking tube (40) surrounding the first connector (1) and the second connector (2).

This structure has a problem in that the moisture flows down the surface of the antenna (3) seeps into the gap between the shrinkage tube 40, the moisture generated inside the connector affects the electrical properties, thereby reducing the system performance. In addition, the shrinkage tube 40, if used for a long period of time, the aging according to the climate and the tube is increased and loosened.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a connector for an antenna configured to change the structure of the first connector so that moisture does not penetrate into the connector.

Another object is to improve the productivity by simplifying the assembly of the connector to simplify the assembly of the parts.

The present invention has a general cylindrical shape, one end portion is provided with a coupling portion coupled to the antenna and the other end portion is made of a shape corresponding to the first connector and the first connector having a coupling groove, the one end portion is In the antenna connector having a coupling protrusion for coupling to the coupling groove of the first connector and the other side is composed of a second connector having a terminal portion to be coupled to the cable, the first connector is to maintain a normal cylindrical shape Cross section A first connector outer conductor having a first coupling groove and a second coupling groove in a shape; A first connector insulator fitted into the cylindrical hollow body inside the first connector outer conductor; A first connector guide fitted into an outer side of the first connector insulator by a cylindrical hollow body; And a first connector pin inserted into an inner center of the first connector insulator.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. 2 is a cross-sectional view showing a fastening state of the antenna connector according to the present invention, as shown in Figure 1, the connector is fastened to the first connector 1 and the first connector 1 are largely fastened to the antenna 3, The other side consists of a second connector 2 which is connected to the cable.

The present invention relates to a connector used for an antenna for a base station that is installed exposed to the external environment, to prevent moisture from rain or snow penetrating between the coupling portion of the first connector (1) and the second connector (2). Cross section of the first connector outer conductor 101 of the first connector 1 The second connector outer conductor 201 of the second connector 2 is fastened to the first coupling groove 101-1, and the cover 401 is connected to the second coupling groove 101-2. It is configured to be fastened.

Here, a screw groove is formed at a predetermined position on one side of the first connector outer conductor 101 of the first connector 1 to be fastened with the screw 301 inside the antenna 3 so that the antenna 3 and the first connector are fastened. 1 Strengthen the bonding force between the connectors (1) and was configured not to seep moisture inside.
