摘要： PURPOSE:To improve the productivity of a card edge type surface mounted connector by surely and completely connecting even a circuit substrate provided with any number of connecting terminals spaced with an equal pitch between the respective two adjacent terminals to the connector via a single insulator. CONSTITUTION:In a connector composed of an insulator 41 having terminal fixation holes 41a arranged in two lines at equi-space pitches and plural number of jack terminals each having a tongue-piece-like contact 11a at one end thereof, the insulator 41 for retentively fixing the jack terminals in parallel with one another while the tongue-piece-like contacts 11a are kept at specified spaces is formed by providing the insulator with the number of the terminal fixation holes 41a corresponding to a number exceeding a required number of the terminals by not less than four terminals. Moreover, the connector is composed by providing it with at least two circuit-substrate guides 42, each having leg-like projections 42-1, 42-2 being able to be fixed to the insulator 41 via the two terminal fixation holes 41a mutually adjacent between the two lines thereof and also each formed with a groove 42a for guiding a circuit substrate 2 to a block portion joined to the leg-like projections along a side-face on one side of the groove so that the circuit-substrate may be positioned between lines of the contacts 11a.

摘要： PURPOSE: To realize easy positioning of a printed circuit board for connection thereof and provide a proper grounding short circuit concurrently by forming a positioning terminal having a tongue piece as integral part thereof on the edge of a connector at the side of a contact lead in the vicinity of both lengthwise ends. CONSTITUTION: A positioning earth terminal 22 is formed to have a U-shaped structure of the first two tongue pieces 22a-1 and 22a-2, and the second one positioning piece 22b. A projection to be inserted ire and fixed to a hole 21a for providing and fixing the terminal 22 is formed on a connecting piece 22. The end area of the piece 22b is bent externally for allowing a circuit board to be easily capped. In this case, two projections 22d of the terminal 22 are inserted in and fixed to each grounding terminal fixing hole 21a of an insulator 21 as shown by arrows G1 and G2. As a result, the connector 2 with the tongue pieces 22a-1 and 22a-2, and the tongue piece 22b can be constituted as shown in Figs (1-2) and (1-3). Consequently, the two opposite terminals 22b of the terminal 22 restrict the breadthwise position of the circuit board, while the tongue pieces 22a-1 and 22a-2 restrict the thicknesswise direction thereof.
