Abstract

A built-in type antenna, with which the electrical connection to a wiring pattern on wiring board can be managed with ease, and the electrical connection can be implemented within a small area. The antenna comprises a base body, on which an antenna element portion is fixed, and a conductive pin having electrical connection with the antenna element portion is disposed in the base body so that the pin can move ups and downs. The bottom end of conductive pin makes an elastic contact to a wiring pattern on wiring board.

Claims

1. An antenna comprising:

a base body;

an antenna element portion attached and fixed on said base body; and

a conductive pin electrically connected with said antenna element portion, which conductive pin being disposed in said base body so that it can move ups and downs.

2. The antenna of claim 1, wherein said base body has a conductive pin holder which holds said conductive pin by having it penetrating through.

3. The antenna of claim 1, wherein said antenna element portion comprises:

a conductive metal sheet; and

an elastic arm, which elastic arm pressing said conductive pin downward.

4. The antenna of claim 3,

wherein said antenna element portion further comprising a side plate, said side plate has said elastic arm, and said side plate is provided with engagement means for engagement with said base body.

5. The antenna of claim 2, wherein

said conductive pin is provided at the top end with a brim, diameter of which brim being greater than hole diameter of said conductive pin holder.

6. The antenna of claim 1, wherein said conductive pin has an elastic section.

7. The antenna of claim 1, wherein

said base body is provided at the upper part with a contacting protrusion, which contacting protrusion being pushed down from the above by the inner surface of equipment case for position restriction in the up-down direction.

8. The antenna of claim 1, wherein

said base body is provided with means to hold a wiring board, which holding means having a holding force that is greater than resilient force of said conductive pin making contact with wiring pattern of said wiring board.

9. A communication equipment having an antenna mounted on the wiring board, which antenna comprising:

a base body;

an antenna element portion attached and fixed on said base body; and

a conductive pin electrically connected with said antenna element portion, which conductive pin being disposed in said base body so that it can move ups and downs,

wherein said antenna is electrically connected with wiring pattern of said wiring board by means of conductive pin disposed in said base body.
