Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of the middle antenna part of the present invention;

fig. 3 is a sectional view of the storage case of the present invention.

In the figure: the antenna comprises a ceramic antenna base body 1, a storage box 2, an extension tube 3, a cable 4, a joint 5, a contact 6, a locking part 7, a bolt 71, a nut 72, a connecting sleeve 73, a circular block 74 and a clamping sleeve 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, an adjustable ceramic antenna for a GPS includes a ceramic antenna substrate 1, a contact 6, a cable 4 and a connector 5, where the cable 4 is electrically connected to the ceramic antenna substrate 1 through the contact 6, and the cable 4 is electrically connected to the connector 5, which is the prior art and is not described herein again.

Fixedly connected with is used for accomodating the receiver 2 of cable 4 on the ceramic antenna base member 1, can accomodate cable 4 in the receiver 2, and the length of accomodating cable 4 can be confirmed according to actual need and the length of flexible pipe 3, should not the overlength.

Receiver 2 keeps away from the fixed and intercommunication of one end of ceramic antenna base member 1 has flexible pipe 3, and cable 4 passes receiver 2 and flexible pipe 3 in proper order and extends to the external world, and in this embodiment, flexible pipe 3 adopts the polymer bellows, for example macromolecular material such as polyethylene, polypropylene can protect the cable and avoid its damage on the one hand, and on the other hand possesses flexible function.

Be provided with retaining member 7 and the cutting ferrule 8 that is used for fixed cable in the receiver 2, in this embodiment, cutting ferrule 8 adopts concave structure (not drawn in the picture), and concave structure indicates that the one side of 4 contacts with the cable is concave type, be convenient for with the surface laminating of cable 4 to increase locking performance, worth mentioning, cutting ferrule 8 can only fix a cable 4 also can fix the reciprocal multistage cable 4 of accomodating.

Referring to fig. 3, the locking member 7 is composed of a bolt 71 and a nut 72, the bolt 71 is screwed with the nut 72, the nut 72 is fixedly connected to the inner wall of the housing case 2, and the bolt 71 is rotatably connected to the ferrule 8. Can rotate bolt 71 through tools such as manpower or vice, bolt 71 realizes driving cutting ferrule 8 axial motion through the threaded connection with nut 72 to realize the locking and the separation of cutting ferrule 8 and cable 4.

The bolt 71 is rotatably connected with the ferrule 8 in the following manner: a connecting sleeve 73 is fixedly connected to one end of the clamping sleeve 8 close to the bolt 71, a circular groove is formed in the connecting sleeve 73, a circular block 74 is arranged in the circular groove, and the bolt 71 extends into the circular groove and is fixedly connected with the circular block 74. The rotational connection is achieved by the circular block 74 sliding in the circular groove, it being worth mentioning that the opening inner diameter of the circular groove should be smaller than the circular block 74, so as to avoid the circular block 74 to come out of the circular groove, whereby the circular groove is T-shaped in cross-section.

When the cable needs to be adjusted, the bolt 71 is rotated by manpower or tools such as a vice, the bolt 71 is connected with the nut 72 through threads to realize axis rotation movement, the clamping sleeve 8 is driven to be separated from the cable 4 at the same time, the cable 4 is in a loose state at the moment, then the cable 4 is pulled outwards by manpower, the telescopic pipe 3 is stressed and extended until the cable 4 is pulled to a proper length, then the bolt 71 is rotated reversely, and finally the clamping sleeve 8 is attached and fixed with the cable 4.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
