Abstract: A connector is mountable on a circuit board and connectable with a mating connector. The connector comprises a housing and a plurality of contacts which are held by the housing. The contacts form two or more contact rows. The contacts of each of the contact rows are arranged in a pitch direction. Each of the contacts has a fixed portion which is fixed to the circuit board when the connector is mounted on the circuit board. The housing has one or more openings each of which is positioned between neighboring two of the contact rows in a predetermined direction perpendicular to the pitch direction. Two or more of the fixed portions extend into one of the openings.

Abstract: A connector has contacts and a housing having holding grooves which accommodate the contacts. Each of the holding grooves has an inner wall extending in a first direction. Each of the contacts has a fixed portion, a contact arm portion and a support arm portion. The fixed portion is fixed to a corresponding one of the holding grooves. The contact arm portion and the support arm portion extend from the fixed portion in the first direction and are disposed apart from each other in a second direction. The contact arm portion has a contact point and is resiliently deformable to move the contact point in the second direction. The support arm portion comes into contact with the inner wall of the corresponding one of the holding grooves at least when the contact arm portion is resiliently deformed so that the contact point comes close to the support arm portion.

Abstract: A plurality of upper plug contacts are each brought into contact with a master elastic piece and a slave elastic piece of a corresponding lower receptacle contact in accordance with elastic deformation of the master elastic piece and the slave elastic piece. A plurality of lower plug contacts are each brought into contact with a master elastic piece and a slave elastic piece of a corresponding upper receptacle contact in accordance with elastic deformation of the master elastic piece and the slave elastic piece. For example, as shown in FIG. 7, in a state where an upper connector and a lower connector are mated, a direction of the elastic deformation of the master elastic piece and the slave elastic piece of each upper receptacle contact is different from a direction of the elastic deformation of the master elastic piece and the slave elastic piece of each lower receptacle contact.

Abstract: A thin connector includes a first connector portion having arrayed first contacts with first contact portions and a second connector portion having arrayed second contacts with second contact portions, each first contact including a first movable portion displaceable in the direction in which the first contacts are arrayed and a second movable portion connected to the first movable portion and displaceable in a direction orthogonal to the direction in which the first contacts are arrayed, the first contact portion being disposed in the second movable portion, the first connector portion and the second connector portion being fitted with each other by sliding relatively in the direction in which the first contacts and the second contacts are arrayed.

Abstract: A contact unit includes a first conduction path in the form of a thin film arranged along a peripheral surface of an insulating elastic body, a second conduction path arranged along the first conduction path, and a connecting conduction path electrically connecting the first and second conduction paths to each other. A frame has a through hole. The frame supports the contact unit so that the first conduction path exposed from both openings of the through hole is brought into contact with connection objects and that the second conduction path is entirely received in the through hole.

Abstract: A connector capable of improving the contact stability. Linear cores of contact members and wires of an insulating holder are weaved to thereby form a net. Conductive path portions of the contact members are disposed such that they extend through a mesh.

Abstract: In a cable connector for use in connecting a cable having a first and a second surface opposite to each other in twin thickness direction thereof, a conductive contact has twin contact portions to be opposed to the first surface and a pivot portion to be opposed to the second surface. A handle is used for pressing the cable between the twin contact portions. The handle has a cam portion positioned between the pivot portion and the cable and is made with a hole in which the pivot portion is inserted with a clearance. The pivot portion has a concavity corresponding to the cam portion. The cam portion engages with the pivot portion so that the handle is rotatable around the pivot portion.
