ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention relates to a flat F-port coaxial electrical connector, and more particularly, to a flat F-port coaxial electrical connector when the terminal structure is engaged to the connector body, a second insulator adapter of the terminal structure is conjoined to an annular stopper protrusion of the conductor body so that the terminal of the conductor body is formed into a flat surface. With this structure, when the electrical connector of the present invention is engaged with a F-type male connector, the mating surfaces can be maintained in smooth and finished state thereby preventing electromagnetic signal leakage.
(2) Description of the Prior Art
Recently, the inventor of the present invention acquired a US patent regarding a coaxial cable connector titled “Flat F-port coaxial electrical connector”. This patent is published in U.S. Pat. No. 6,113,431 dated Sep. 5, 2000. In aforesaid patent, an improvement was made to eliminate shortcomings arose from the conventional technique wherein a plastic terminal was directly riveted to the connector body after fitted with an annular collar, and in stead, in the aforesaid patented invention, flat sections at the two extremities of the cable connector body were formed in order to maintain flatness and smoothness when it was engaged with a F-type male connector thereby preventing electromagnetic signal leakage.
After being carried out further study and experimentation, the present inventor discovered there is still an improvement can be made for engagement technique of the aforesaid invention between the containment hole and the second insulating adapter so that production cost can be further reduced and manufacturing efficiency more improved, and similarly, there will be formed flat surfaces at both side of the connector body terminal.
SUMMARY OF THE INVENTION
Accordingly, it is a main object of the present invention to provide a flat F-port coaxial electrical connector having an annular stopper protrusion to be inlaid into and fixedly engaged with a second insulating adapter of the terminal structure.
It is another object of the present invention to provide a flat F-port coaxial electrical connector having an annular sleeve provided at a port formed in the connector body so as to form planar surfaces at the connector body terminal, and by engaging the annular sleeve fixedly with the terminal structure, when the connector body is engaged with a F-port male connector, the mating surfaces can be maintained in smooth and finished state thereby preventing electromagnetic signal leakage.
For fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings below. Meanwhile, the accompanying drawings are provided for purposes of reference and explanation, and by no means are construed as limitations applicable to the invention herein.
