In a specific embodiment, a fourth through hole or an elongated slot is formed in the conductive stud 310 along the length direction of the conductive stud 310; the vehicle-mounted antenna assembly further comprises a connecting cable; the connecting cable is located in the fourth through hole or the long groove, and is used for connecting the circuit board 20 and the automobile communication unit.

In the embodiment of the present application, the connection cable includes a harness connector cable (i.e., a square connector cable in fig. 1) and an FM antenna connection cable (i.e., a round-head cable in fig. 1).

For example, referring to fig. 2, the conductive stud 310 is provided with an elongated slot extending along the length direction of the conductive stud 310, through which the connection cable of the vehicle antenna assembly can extend, so as to effectively protect the connection cable from being damaged.

Through also can set up in conductive double-screw bolt 310 along conductive double-screw bolt 310 length direction's fourth through-hole for the connecting cable in the vehicle-mounted antenna subassembly can be worn out from the fourth through-hole, avoids connecting cable to take place the damage.

The utility model also provides a vehicle, wherein the vehicle is provided with the vehicle-mounted antenna assembly.

While embodiments of the present utility model have been shown and described, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that changes, modifications, substitutions and alterations may be made therein by those of ordinary skill in the art without departing from the spirit and scope of the utility model, all such changes being within the scope of the appended claims.
