Abstract
Abstract An electrical connector with upper contacts, for a flexible flat cable. The connector is an electrical connector for gripping a flexible flat cable by upper contacts, and the connector includes two kinds of contact members for gripping the flexible flat cable, a housing for receiving the contact members, and an opening/closing type actuator. The contacts of the two kinds of the contact members are spaced from each other in an insertion direction, and the contact members are alternately arranged in the housing so as to form staggered rows of the contacts. With a first kind of contact members, FPC can be inserted without insertion force, and with a second kind of contact members, the FPC can be inserted with low insertion force. The connector is characterized in that is has a zero insertion force (Z.I.F.) and low insertion force (L.I.F.) mechanism structure for insertion of the FPC, where the structure is constructed from the first contact members and second contact members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
377 words
An electrical connector characterized by being an electrical connector for gripping a flat flexible cable, said connector having two types of contacts for gripping the aforementioned flat flexible cable, a body for housing said contacts, and an actuator which opens and closes, having a structure wherein there is a space in the insertion direction between each of the contact points of the aforementioned two types of contacts, and a row of contact points in a staggered form is constituted by aligning said each contact alternately within the aforementioned body, in the contacts of the first type, one end of a first contact beam has a first contact point that comes into contact with a first surface of a flat flexible cable and one end of a fixed base beam supports a second surface of the aforementioned flat flexible cable being connected, and each of the opposing other ends of the first contact beam and the fixed base beam are free ends, said first contact beam has an actuator-driven portion in the vicinity of the aforementioned free end, said actuator-driven portion having a structure such that, when the actuator is open, the aforementioned free end of the aforementioned first contact beam is elastically deformed to open the aforementioned free end in the opposite direction from the aforementioned base beam, and when the actuator is closed, by releasing the elastic deformation of the aforementioned free end of the aforementioned first contact beam, the aforementioned first contact point is put into contact with the first surface of the aforementioned flat flexible cable, the second type of contact is integrally formed by an opposing second contact beam and fixed base beam through a joining portion, said second contact beam has one free end having an actuator-driven portion in the vicinity of said second contact beam, and another free end having a second contact point which comes into contact with the first surface of the aforementioned flat flexible cable, and when the actuator is closed, the driving portion of the actuator presses on the aforementioned one free end of a second contact beam to elastically deform the aforementioned second contact beam, whereby the second contact point of the aforementioned other free end presses on the first surface of the flat flexible cable.
