  • Publication number: 20080085629
    Abstract: The present invention provides an improved connector structure in which a connector is structured from a conducting body, electric conducting terminals and fastening members, wherein terminals, which electrically connect with a circuit and connecting terminals, are disposed interior of the conducting body. The fastening members extend from the conducting body, and the fastening members enable the conducting body to embed into a circuit board, thereby enabling the connector to fasten into corresponding holes of the circuit board by means of the fastening members, and thus achieve the objective of increasing positioning strength.

  • Patent number: 7311527
    Abstract: A connector structure includes a connector structured from a cover casing, an insulating body, signal terminals and staggered terminals. The insulating body is disposed within the cover casing, and connecting portions and soldering portions extend from the cover casing. Moreover, a containing space is defined within the insulating body. Ribs having a guide positioning function are disposed within the containing space, and clasp grooves that fixedly hold staggered terminals, second passages and first passages having signal terminals penetrate therethrough are located within the insulating body. Each of the staggered terminals includes a pressure terminal and an earth terminal, which are in an up/down and right/left juxtaposed configuration. Electric conduction portions of the signal terminals enable electrical connection with a circuit board, thereby enabling the connector to achieve the objective of electrical conduction, and increase electrical conduction efficiency and reduce manufacturing cost.

  • Patent number: 6843673
    Abstract: A coaxial connector structure including an insulating member, a fixed metal terminal, a movable metal terminal and a conductive shade. The insulating member includes a bendable connecting section, an insulating seat and an insulating cover connected with the insulating seat via the connecting section. The insulating seat is formed with multiple insertion sockets. The fixed and movable metal terminals are formed with insertion plates which can be inserted and located in the insertion sockets. When assembled, the respective parts and internal elements of the insulating seat and insulating cover are easily accurately located so that the assembling procedure is simplified and the quality of the product is enhanced. The conductive shade is firmly located around the insulating member to cover the same so as to shield the product from electromagnetic wave and enhance the connecting strength.
