Connector

Claim 2

A connector comprising: a connector body formed by an insulating member of substantially rectangular parallelepiped configuration and having a plug hole made in its front face to extend in its lengthwise direction; a plurality of contacts arranged in said hole along at least one of two parallel inner side walls of the plug hole in its lengthwise direction; a plurality of contact terminals respectively connected to said contacts and led out on at least one of two parallel side surfaces of the connector body parallel to its lengthwise direction, said contact terminals extending along the side surface in the direction of insertion of a plug into the plug hole; and insertion depth setting means formed on the outer peripheral surface of the connector body for controlling the depth of insertion of the connector body in a plurality of stages when that portion of the connector body on which the contact terminals are formed is inserted into an insertion hole made in a printed-circuit board on which the connector is to be loaded; each of said contacts and each of the corresponding contact terminals being formed as a unitary structure comprising a substantially U-shaped resilient conductor strip an intermediate portion of which is fixedly buried in the connector body by molding, one end portion of each of said resilient conductor strips constituting the contact terminal portion of said strip, said one end portion being embedded in said connector body with the outer surface of said one end portion being exposed in substantially flush relation to the side surface of said connector body.

Claim 3

A connector for insertion into a printed circuit board comprising: a connector body formed of an insulating member, said body being of substantially rectangular parallelepiped configuration having a front face, a rear face, two elongated side walls which define side faces extending parallel to each other, and two end faces, said front face having an elongated substantially rectangular plug hole therein which extends between said two side faces in parallel thereto; insertion depth setting means formed on the outer peripheral surface of said connector body for controlling the depth of insertion of said connector body into an insertion hole in a printed circuit board in a plurality of stages, said insertion depth setting means comprising guide pieces respectively formed integrally with said end faces of said connector body to project outwardly therefrom and stepped portions formed on each of said side walls to define a thicker portion and a thinner portion of each said side wall adjacent said front face and said rear face, respectively, the distance between said rear face and either of said guide pieces being less than the distance between said rear face and said stepped portions; and an array of spaced, parallel conductor strips penetrating through said thicker portion of one of said side walls from said front face towards said rear face of said connector body, one end portion of each of said conductor strips being bent into said plug hole to form a contact and the other end portion of each of said conductor strips being led out as a contact terminal from said stepped portion to be substantially flush with the side face of said thinner portion.

Claim 4

A connector for insertion into a printed circuit board comprising: a connector body formed of an insulating member, said body being of substantially rectangular parallelepiped configuration having a front face, a rear face, two elongated side walls which define side faces extending parallel to each other, and two end faces, said front face having an elongated substantially rectangular plug hole therein which extends between said two side faces in parallel thereto; insertion depth setting means formed on the outer peripheral surface of said connector body for controlling the depth of insertion of said connector body into an insertion hole in a printed circuit board in a plurality of stages, said insertion depth setting means comprising guide pieces respectively formed integrally with said end faces of said connector body to project outwardly therefrom and stepped portions formed on each of said side walls to define a thicker portion and a thinner portion of each said side wall adjacent said front face and said rear face, respectively, the distance between said rear face and either of said guide pieces being less than the distance between said rear face and said stepped portions; and an array of spaced, parallel conductor strips penetrating through said thicker portion of one of said side walls from said front face towards said rear face of said connector body, one end portion of each of said conductor strips being bent into said plug hole to form a contact and the other end portion of each of said conductor strips being led out as a contact terminal from said stepped portion to be substantially flush with the side face of said thinner portion.

Claim 5

A connector according to claim 2 wherein said distance between said rear face and said guide pieces is substantially equal to the thickness of the printed-circuit board.

Claim 6

A connector according to claim 2 wherein said distance between said rear face and said guide pieces is greater than the thickness of the printed-circuit board.

Claim 7

A connector according to claim 2, 3 or 4 including a second array of spaced, parallel conductor strips penetrating through said thicker portion of the other of said side walls, the conductor strips in said second array being disposed in opposing relation to respective ones of the conductor strips in said first-mentioned array.

Claim 8

A connector according to claim 2, 3 or 4 wherein intermediate portions of said conductor strips extending through said thicker portion of said side wall are fixedly buried in said side wall by molding.
