Abstract: An electric connector enclosed with an insulating housing (2) and having a plurality of contacts (10) arranged in parallel rows and along internal surfaces (3a) of the insulating housing. Each contact (10) has a contacting portion (11) exposed in the internal surface and a solderable lead end (12) extending outwardly through a bottom (4) of the housing. A bent anchoring portion (13) is formed as a part of each contact and continuing from an upper end of the contacting portion (11) and bent outwardly to reach an external surface (3b) of the insulating housing, so that the bent anchoring portion (13) is embedded in the housing (2) so as to hold the contacts at regular intervals and protect the contact from deviating from the insulating housing.

Abstract: Either of male and female connectors (1,2) fitting in or on each other has a housing (3) whose side face has a locking lug (5). The other connector has on a top of its housing (6) a lockable cantilever arm (13) corresponding to the lug, and a free end of the arm elastically deforming itself has a pawl (16) engageable with and disengageable from the lug (5). A tapered ridge (17) extends along and beside the arm (13) and is shaped such that its height gradually increases inwardly from the arm's portion near its basal end towards the free end of said arm. Any operator may insert a tool (30) having a flat and narrow bit in between the top (6a) of the other connector's housing (6) and the ridge (17), from this housing's side where the basal end is located so that the tool's bit will force outwards the free end of the arm (13) until its pawl (16) is disengaged and unlocked from the lug (5).

Abstract: A connector for printed circuit boards, particularly for flexible ones such as FPC or FFC, has an insulating housing (2) with a recess (7) opened up and base contacts (3) held in the housing at regular intervals and each having a resilient beam (14) and an arm (5) integral with the beam. Each beam has a conductive protrusion (17) in the recess, and each arm extending along the housing's top into the recess has a pivotal end (18) facing the protrusion. An insulated pressing cover (4) engaging with the pivotal ends is rotatable between its pressing position adjacent to and its releasing position remote from the protrusions. The pivotal ends (18) lock the cover then pushing the circuit board (30) against the resilient beams (14). The cover has cover contacts (20) rotatably engaging with the pivotal ends and corresponding to the base contacts (3), so that the pivotal ends, the cover contacts (20) and the printed circuit board (30) are electrically connected to each other at the pressing position.

Abstract: A connector holder (1) has an elongate front wall (2), an elongate and partitioning center wall (3) formed integral with, perpendicular to and along the inner edge of the front wall, and end walls (4, 4') extending perpendicular to the center wall and located at opposite ends of same. The end walls have latch means (6, 7 and 8) for engagement with the connectors of the pressure contacting type. A pair of spaces (5) for receiving the connectors are provided such that a side of each space facing the front wall is opened, with another side confronting the center wall also opened. The connector holder (1) further has lugs (11) that are capable of engaging with the entrances (26) of compartments formed in each connector (20), so that the electric wires received in the compartments are surely held in place.

Abstract: A connector housing (15) having compartments (16) for receiving socket-shaped bodies (12) of contacts (11) are prepared. The housing has slots (17) extending in parallel with the compartments. Further prepared are the socket contacts (11) each having an unfinished lead (13) that continues from the body (12) and has a bent portion (31) adjacent to it and continuing to a straight lead (13') in parallel with the body. Then, the socket-shaped body (12) of each contact (11) will be inserted in compartment (16), with the straight lead (13') being simultaneously inserted in the slot (17), so that the lead's end portion is exposed out of the housing (15) and subsequently bent to form a connectable leg (14) protruding downward from the housing (15), such that the leads are strongly held in the housing and reliably connected to a printed circuit board, besides the housing is protected from distortion when molded.
