Abstract

The micro coaxial connector includes a signal terminal, a main body, and two grounding elements. The signal terminal has a pair of tag-like contact arms and bending arms at a front and rear end thereof, and a strip plane at a middle section thereof. The contact arms are for contacting with a base of a printed circuit board (PCB). The main body is for receiving the signal terminal and serving as an insulation. The two grounding elements are separated designs. The cylindrical-shaped first grounding element is for receiving and fastening the main body, and has a pair of extension arms for providing the coaxial cable with suitable clamping forces. The second grounding element is a cover-like body, and has a strip-like projection for increasing strength against bending of the second grounding element and preventing loosening of components.

Claims5

Dependent claims

A micro coaxial connector for elevating quality yielding rate, enhancing electrical characteristics and increasing economical values, comprising:

a signal terminal being long and thin in shape;
and having a pair of downwardly extended contact arms and bending arms at front and rear ends thereof, respectively, and a strip portion at a middle section thereof;
wherein:
the contact arm for contacting with a base of a printed circuit board (PCB), and the two bending arms formed with a clamping aperture in between;
a main body having a cylindrical protruding portion at a front portion thereof, a pressing tag at a front end thereof, a dented carrier portion at an appropriate position thereof for correspondingly holding the strip portion of the signal terminal, a hollow portion vertically penetrated at a front portion thereof for placing the contact arms of the signal terminal, and a dented receiving portion at a rear end thereof for receiving the bending arms;
two grounding elements as separated designs;
wherein:
a first grounding element is cylindrical in shape;
and has a recess at an appropriate position thereof for placing the protruding portion of the main body as well as receiving and fastening the main body, and a pair of extending arms at two sides thereof for providing the coaxial cable with suitable clamping forces;
and
a second grounding element is a cover-shaped body;
and has a strip-like projection at an appropriate position thereof for increasing strength against bending of the grounding element and avoiding disassembly thereof;
wherein the second grounding element has bending arms at a front end and two sides thereof, thereby preventing electromagnetic interference (EM) and serving as planes for applying force when the connector are pulled out by tools.
