Abstract
The utility model relates to a direct-current load controlling switch for a communication base station, which comprises a case, an external terminal , a controlling circuit binding post and a mounting frame at the bottom of the case. The lower portion of the terminal is inset into a case body of the case by injection molding, the controlling circuit binding post is pressed into a bottom plate of the case in an interference manner, a cylindrical cavity of a controlling current waterproof plug is further arranged on the case and matched with the outline of the waterproof plug, the lower end of the cavity is fixedly connected with the bottom plate of the case, and the controlling circuit binding post is positioned inside the cavity. The direct-current load controlling switch is simple and reasonable in structure, convenient in mounting, long in service life and fine in sealing and waterproof performance, and is an ideal direct-current load controlling switch for communication base stations.
Description
Technical field
The utility model relates to a kind of control switch, particularly a kind of communication base station DC load control switch.
Background technology
Communication base station is general to be built in the open air, is subjected to natural environment influence bigger.The communication base station DC load control switch water resistance of using is relatively poor at present, as being in for a long time in the wet environment, very easily produces fault, influences the operate as normal of communication base station.
The utility model content
Content of the present utility model provides a kind ofly has the communication base station DC load control switch of waterproof, moisture-proof function to overcome the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: communication base station DC load control switch, comprise casing, external binding post, Control current binding post and the installing rack of being located at bottom of shell, the injection moulding of described binding post bottom embeds in the housing of casing, the interference of Control current binding post is pressed into chassis backplane, on casing, also be provided with Control current waterproof plug chamber groove, this chamber groove is a tubular structure, the outline of its tubular inner chamber and waterproof plug is suitable, this groove lower end, chamber and chassis backplane are fixedly connected, and the Control current binding post places in the groove of chamber.
Intracavity bottom at described chamber groove also is provided with ring washer.
Between described chassis backplane and installing rack, also be provided with the insulative water-proof pad.
The cross section of described installing rack is a portal structures, and the frame bottom of portal structures is extended with the installation leg respectively laterally.
The obtained technique effect of the utility model is:
Owing to adopt the injection moulding of binding post bottom is embedded in the housing of casing, the interference of Control current binding post is pressed into chassis backplane, is provided with the insulative water-proof pad between chassis backplane and installing rack, has guaranteed the water-tight of the utility model internal electronic component; On casing, be provided with Control current waterproof plug chamber groove, realized the water-tight behind the external waterproof plug; Installing rack is at the structural design of base station installation situation, ensured of the present utility modelly rationally to install and use.In addition, it is simple and reasonable, simple installation, long service life.
