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.

Claims

1. 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.

2. A micro coaxial connector for a coaxial cable comprising:

a) a signal terminal having;

i) a strip portion;

ii) two contact arms located on a first end of the strip portion and selectively engaging a base of a printed circuit board; and

iii) two bending arms located on a second end of the strip portion and having a clamping aperture, a central conductor of the coaxial cable is inserted into the clamping aperture and connected to the signal terminal by the two bending arms;

b) a main body having;

i) a pressing tag located on a first end thereof;

ii) a cylindrical protruding portion on the first end thereof adjacent to the pressing tag, and having the contact arms inserted therein;

iii) a dented receiving portion located on a second end thereof and having the two bending arms inserted therein; and

iv) a dented carrier portion located between the cylindrical protruding portion and the dented receiving portion, and having the strip portion inserted therein, the pressing tag covering a top of each of the strip portion, the two contact arms, and the two bending arms;

c) a first grounding element being a cylindrical shape and having;

i) a recess having the cylindrical protruding portion inserted therein; and

ii) two extending arms extending around the second end of the main body and engaging the coaxial cable; and

d) a second grounding element connected to the first grounding element with the main body located there between and having a grounding element strip portion located above the pressing tag.

3. The micro coaxial connector according to claim 2, wherein the second grounding element includes three first bending arms located on a first end and two opposing sides thereof, each of the three first bending arms overlapping a side of the first grounding element.

4. The micro coaxial connector according to claim 2, wherein the second grounding element includes two second bending arms extending around a bottom of the first grounding element.

5. The micro coaxial connector according to claim 2, wherein the second grounding element includes two pairs of third bending arms connecting the second grounding element to the coaxial cable.
