Abstract: A joint structure of electronic element for linking circuit board and electronic element is provided. The joint structure of an electronic element for being electrically connected to a circuit board has at least one slot positioned thereon. And, the joint structure of the electronic element includes: at least one terminal which has a curved portion including a deflected angle with a normal line of a plane of the circuit board, wherein when the joint structure of the electronic element is connected with the slot, the terminal produces an elastic stress through suffering a jostle from the slot so as to urge against the slot for forming an electrical connection therebetween.

Abstract: A connector having a relatively high terminal density is provide for reducing the requirement of the electric currents in one signal terminal and increase the conducting efficiency. The connector includes plural first conducting components each having a first terminal and extended laterally, plural second conducting components each having at least two second terminals and extended laterally, and an insulating housing having plural slots for mounting the plural first conducting components and the plural second conducting components, wherein each first conducting component and each corresponding second conducting component are mounted in the respective slot, so as to contain a contact pad having plural pins.

Abstract: The present invention provides a dust-proof electrical connector. This connector includes an outer sleeve and an inner sleeve as a receiving end for connecting a corresponding connector. The inner sleeve contacts a first contact terminal disposed on the corresponding connector. A second contact terminal is pierced through the outer sleeve and inner sleeve, for forcing and contacting the first contact terminal when the inner sleeve is moved to a specific position relative to the outer sleeve.
