The present invention relates to a connection structure for a printed wiring board to be electrically connected to a FPC. The FPC has an elongated substrate, and plural conductors are laminated on a surface of the substrate for extending along an axial direction of the substrate. The printed wiring board has an insertion opening provided at an edge surface for being inserted by a top end portion of the FPC, and plural line connecting terminals formed on an internal wall surface of the insertion opening. The top end portion of the FPC has a slider including plural elastic deformable first contacts, and a first housing for holding the plurality of contacts. The FPC is inserted into the insertion opening of the printed wiring board such that one end of the first contact presses the conductor and the other end of the first contact presses the line connecting terminal. The FPC can be connected to the printed wiring board on an edge surface thereof, allowing circuit elements to be mounted in high density, and improving freedom in designing wiring patterns.

Connection structure for printed wiring board

A double-sided flexible printed circuit comprises: an electrically insulating base; a first copper layer having a first conductive pattern; a second copper layer having a second conductive pattern, the second conductive pattern disposed offset from the first conductive pattern; and electrically insulating coverlays. A first area opposing a first contact point of first contacts that press upon the first conductive patterns, is reinforced by copper foil extending from the second conductive patterns, and a second area opposing a second contact point of second contacts that press upon the second conductive patterns, is reinforced by copper foil extending from the first conductive patterns.

Double-sided flexible printed circuits

A connector of upper contact type for an FPC comprising a cover housing constituted of synthetic resin alone. The housing includes first contacts and second contacts alternately arranged in parallel on a line. Each of the first contacts has an elastic arm coming into contact with an upper contact point of FPC when the cover housing is closed. On the other hand, each of the second contacts has a tuning-fork-shaped contact constituted of a pair of a short arm and a long arm, the short arm coming into contact with the upper contact point of the FPC so that the tuning-fork-shaped contact may exert a coupled force on the FPC when the cover housing is closed. With such a configuration, this connector reduces deformation of the cover housing while eliminating use of any reinforcing metal member in the cover housing.

Connector

A connector comprises a housing and a cover housing. The housing has a recess formed for insertion of a FPC. The housing comprises a first contact, a second contact and a third contact. The first contact and the second contact includes a first arm, a second arm, and a horizontal leg. The third contact includes a fixing arm, an elastic arm opposing the fixing arm, and a connection leg connecting said fixing arm with said elastic arm. A cam is arranged between the elastic arm of the third contact and the bottom surface of the recess of the housing for locking at a tip of the elastic arm.

Flexible printed circuit board connector

An FPC connector comprises: a housing in which is formed a concave portion into which an FPC with a pair of engaging convex portions arranged on two flanks of a terminal portion of the FPC, is inserted; a cover-housing for covering, with opening and closing enabled, the concave portion of the housing, the housing having a pair of protrusions that protrude from a bottom face of the concave portion and are latched by the pair of engaging convex portions; and a pair of metal reinforcing plates, adjoining two flanks of the pair of protrusions, the metal reinforcing plates having convex portions that are latched by the protrusions and the engaging convex portions.

FPC connector

A connector ( ) for a flexible circuit board ( ) has a housing ( ), a pressing means ( ), and parallel contacts ( ) each having a conductive arm ( ) and arranged at a pitch to form a row in the recess ( ) of the housing. The pressing means ( ) can be swung to close the recess so that an inner end portion of the flexible board ( ) overlying the conductive arms ( ) will be pressed down onto these arms. Reinforcement metals ( ) face one another over the row of the contacts ( ) and are attached to opposite sides ( ) of the housing ( ), so as to be soldered to a rigid printed circuit board. Each reinforcement metal ( ) has a resilient support ( ) for urging upwards the flexible board ( ) in a direction away from the conductive arms ( ) so as to keep the board in place.

Connector for a flexible circuit board

Connector for flexible circuit boards

An electrical connector for flexible printed board ( ) has a housing ( ) with an opening, and a cover ( ) being rotatable about a predetermined pivotal axis for opening or closing the opening. A resilient piece ( ) of a fork-shaped contact ( ) has a first and a second branches ( ) branched from a free end ( ) thereof. The second branch ( ) includes a contact point coming into contact with a flexible printed board ( ) inserted in an insertion space ( ). One edge of the cover ( ) is provided with a regulating portion ( ) interposed between the first and second branches ( ). The regulating portion ( ) restricts bidirectional displacements of the free end ( ) of the resilient piece ( ) within a predetermined range.

Electrical connector for flexible printed board

A connector includes a cover adapted to openably close an opening of a housing, and a locking mechanism for locking the cover in a closed position. The cover is provided with first metallic reinforcement means which is partially embedded in the cover during the molding thereof. Second metallic reinforcement means is fixed to the housing. The cover is locked in the closed position by bringing an engagement portion of the first reinforcement means into engagement with an engagement portion of the second reinforcement means.

An electrical connector for flat cable which removably connects a flat cable at its end. A housing defines an insertion space for insertion of the end of the flat cable in a predetermined direction. A retainer is connected to the housing as allowed to slide substantially along the predetermined direction. A reinforcement member made of metal is fixed to the housing. The reinforcement member inhibits the removal of the retainer from the housing.

Electrical connector for flat cable

A retainer for an electrical connector presses an end of a flat cable into contact with a plurality of contacts in an insertion space, the flat cable inserted in the insertion space of a housing of the electrical connector. The retainer includes a main body formed of a synthetic resin, a pair of connection arms made of metal and fixed to the main body. The connection arms are connected to the housing as allowed to slide in a predetermined direction.

Retainer for electrical connector and electrical connector

An electrical connector for flexible printed board includes a housing with an opening, and a cover rotatable about a pivotal axis for closing or opening the opening. When the cover is closed, a pressure portion disposed along one edge of the cover is clamped between a flexible printed board on a resilient piece of a fork-shaped contact and a fixing piece of the contact while pressing the flexible printed board against the resilient piece. A wire fixed within the cover includes a pair of opposite ends projecting from lateral sides of the cover along the pivotal axis, and an intermediate portion circumventing the pressure portion as spaced a distance from the pivotal axis.
