ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and particularly to an electrical connector for use in a portable wireless telecommunication device to enable the device to exchangably connect with different external antennae.
2. The Prior Art
Following the development of communication technology, portable wireless telecommunication devices are becoming increasingly popular. To meet different operating circumstances, the device needs to be exchangably connected with different antennae. To achieve this, a connector which can exchangably connect with coaxial connectors in electrical connection with different antennae is mounted in the device. U.S. Pat. No. 5,278,570 discloses such a connector. However, this prior art connector has a relatively complicated structure resulting in a high cost.
Hence, an improved connector is needed to eliminate the above mentioned defects of current connectors.
SUMMARY OF THE INVENTION
Accordingly, an objective of the present invention is to provide an electrical connector for a portable telecommunication device which enables the device to connect with an external antenna, wherein the connector has a simple structure and a low cost.
To fulfill the above mentioned objective, according to the preferred embodiment of the present invention an electrical connector for use in a portable wireless telecommunication device having a built-in antenna to enable the device to connect with an external antenna, includes a dielectric housing, a metallic shielding, and first and second conductive contacts. The housing has a rectangular base portion defining a first chamber exposed to a first lateral side thereof and a second chamber exposed to a second lateral side thereof and communicating with the first chamber via a passage, and a cylindrical upper portion projecting from a middle of the base portion and defining a hole in communication with the first chamber. The first contact is fixedly received in the first chamber with a contact portion located just below the hole and a tail portion extending along a bottom of the base portion of the housing toward the first lateral side thereof for being soldered to a PCB to electrically connect with receiver/speaker circuitry of the telecommunication device. The second contact is fixedly received in the second chamber with a contact portion extending through the passage to electrically engage with the contact portion of the first contact by a spring force of the first contact when the connector is not engaged with a mating connector, and a tail portion extending along the bottom of the base portion of the housing for being soldered to the PCB to electrically connect with the built-in antenna. When a mating connector connecting with an external antenna connects with the connector, a conductive pin thereof extends through the hole of the upper portion of the housing into the first chamber to engage with the contact portion of the first contact thereby preventing engagement with the second contact. A metallic shielding encloses the upper portion and front and rear sides of the base portion of the housing. The shielding has two grounding tabs extending beyond the bottom of the base portion of the housing.
