Abstract
A housing (30) has a terminal accommodation part (32) for accommodating a terminal (20) and a circular arc wall (34) constituting an insertion opening (36) into which a socket (10) can be inserted. Slits (41) are formed on an upper end of the circular arc wall (34) to form elastic pieces (42). A protrusion (44) projects inwardly on each elastic piece (42) and is disposed to cover an upper portion of each contact piece (25) of the terminal (20). A guide surface (46) inclines inward on each protrusion (44). The lower end of the socket (10) slides on the guide surface (46) so that the socket (10) becomes almost coaxial with the insertion opening (36).
Claims10
A connector comprising:
- a housing having an insertion opening with an opening end into which a socket can be inserted;
- and
- a terminal accommodated in said housing by disposing said terminal in said insertion opening,
- wherein said terminal has a plurality of contact pieces that are annularly disposed receiving said socket inserted into said insertion opening, the contact pieces being capable of contacting a peripheral surface of said socket, and
- a plurality of protrusions formed on an inner peripheral surface of said insertion opening, said protrusions projecting radially inwardly from portions of said contact pieces closest to the opening end of the insertion opening such that said contact pieces are locked in said insertion opening of said housing by said protrusions;
- and
- a guide surface for guiding said socket to a predetermined position at which said socket matches said insertion opening is formed on an outer edge of said protrusion, whereby said terminal is inserted into the housing in an insertion direction corresponding to an insertion direction of the socket and is unremovably held by the protrusions after the insertion to a predetermined depth.
A connector, comprising:
- a terminal having an axially extending inner conductor and substantially cylindrical outer conductor substantially concentric around the inner conductor, said outer conductor defining a selected outside diameter and a selected height, said outer conductor being defined by plurality of circumferentially spaced contact pieces;
- and
- a housing having a bottom wall and a circular arc wall extending up from the bottom wall to a top end defining an insertion opening, said circular arc wall defining an inside diameter at least equal to the outside diameter of the outer conductor and being defined by a plurality of circumferentially spaced elastic pieces, each said elastic piece having an inwardly projecting protrusion spaced from the bottom wall by a distance at least equal to the height of the outer conductor, said protrusions defining an inside diameter less than the outside diameter of the outer conductor, each said protrusion having an inwardly and downwardly sloped guide surface, said outer conductor being engaged in said circular arc wall and held by the protrusions.
