Abstract
Provided is a GPS reception apparatus capable of combining an antenna unit and a host unit together, without affecting the positioning function of the GPS. The GPS reception apparatus comprises an antenna unit, a host unit, and a cable connecting the two units. Further included is a housing, which is internally provided with an antenna cavity, a host cavity, and a cable cavity adjacent to the antenna cavity and the host cavity, wherein the antenna unit is fixed inside the antenna cavity; the host unit is fixed inside the host cavity; and a cable aperture is arranged between the cable cavity and the antenna cavity as well as between the cable cavity and the host cavity respectively for arranging the cables connecting the antenna unit and the host unit.
Description
Technical field
The utility model relates to a kind of GPS equipment, especially a kind of GPS receiving trap.
Background technology
The GPS receiving trap is divided into antenna element and main computer unit two large divisions, with cable these two unit are linked together, these two unit be generally two independently parts be placed on the scaffold tower, and, antenna element and main computer unit need be made an integral body along with the volume-diminishedization of GPS receiving trap and the development trend of weight savingization.
But, cause inefficacy of GPS positioning function or effect undesirable owing to after gps antenna and other electronic circuit be attached to certain tightness degree, can produce electromagnetic compatibility problem.
The utility model content
The purpose of this utility model provides a kind of antenna element and main computer unit can being combined, and does not influence the GPS receiving trap of GPS positioning function.
Realize the GPS receiving trap of the utility model purpose, comprise antenna element, main computer unit and the cable that connects antenna element and main computer unit; Also comprise a housing, be provided with antenna chamber, main frame cavity, the cable cavity adjacent with the main frame cavity in the described housing with described antenna chamber; Described antenna element is fixed in the antenna chamber, and described main computer unit is fixed in the main frame cavity, is provided with cable aperture between described cable cavity and described antenna chamber and the main frame cavity, is used to place the cable that connects antenna element and main computer unit.
Described antenna chamber and cable cavity are positioned at the top of described main frame cavity.
Described cable cavity is positioned at the centre of described antenna chamber and main frame cavity.
Described antenna chamber, cable cavity and main frame cavity all are provided with opening and gland bonnet.
GPS receiving trap of the present utility model, by the housing that is provided with a plurality of cavitys in antenna element and main computer unit are kept apart, by the cable in the cable cavity antenna element and main computer unit are coupled together then, eliminated the interference between antenna element and the main computer unit, guarantee the receptivity of GPS receiving trap, solved the integrated electromagnetic compatibility problem that produces; And shell structure of the present utility model is simple, low cost of manufacture, and installation and maintenance is easy.
Description of drawings
Fig. 1 is the structural representation of the utility model GPS receiving trap.
