ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to electrical connectors, and more particularly to a coaxial cable termination connector for mounting directly on a printed circuit board (PCB).
2. Description of the Prior Art
Coaxial connectors are often used to transmit signals in high-frequency applications. See U.S. Pat. Nos. 5,921,793 and 6,030,231, for example.
U.S. Pat. No. 5,921,793 discloses a coaxial connector which has a conductive housing, a dielectric sleeve, a center contact, and a central insulator. The dielectric sleeve is received in the conductive housing, the center contact is received in the central insulator and a pin contact section of the center contact is received in a cavity of the dielectric sleeve for electrically mating with a complementary plug connector.
U.S. Pat. No. 6,030,231 discloses another coaxial connector for mounting on a printed circuit board (PCB). The coaxial connector has a pipe like connector, a projection, and a center connector received in the pipe like connector. The projection forms a plurality of grounding pins for electrically connecting with grounding tabs on the PCB. The center connector forms an attachment pin on a free end thereof for electrically connecting with a conductor tab on the PCB. The pipe like connector and the center connector received therein are adapted to electrically mate with a complementary plug connector.
However, these conventional coaxial connectors need to cooperate with complementary plug connectors to achieve signal transmitting performance, and thus the quality of transmitted signals. Furthermore, the reliable engagement between the coaxial connectors and the complementary plug connectors is not ensured.
Hence, an improved connector is needed to eliminate the above mentioned defects of conventional connector assemblies.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a coaxial cable termination connector which directly connects a coaxial cable to a printed circuit board (PCB) while eliminating a mating connector thereby ensuring a more reliable electrical connection between the coaxial cable and the PCB on which the connector is mounted.
A coaxial cable termination connector of a preferred embodiment of the present invention has a metal shell, a metal retainer and an insulative insert module respectively received in the metal shell, and a center pin received in the insert module. The shell has a cylindrical portion defining a cavity, and the insert module and the retainer are received in the cavity. The shell further has a base portion and the base portion has a plurality of grounding pins symmetrically extending downwardly therefrom. The center pin has a connecting portion connecting with an inner core conductor of a coaxial cable. A metal braided shielding layer of the coaxial cable electrically connects to the retainer, and thus to the shell and the grounding pins.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of a preferred embodiment when taken in conjunction with the accompanying drawings.
