A contact configured to be retained and arranged in an insulating object includes a contact portion that is configured to come into contact with a counterpart object, a connecting portion connectable to an object to be connected, a main body portion having two side walls and a joining wall that joins the side walls, the main body portion having a substantially U-shaped cross section, first and second contact pieces protruding from the two side walls and extending along a direction of mating with a counterpart object, and first and second contact portions disposed at free end parts of the first and second contact pieces, respectively. The first and second contact portions each has a curved shape and configured to come into contact with the same surface of the counterpart object. The first and second contact portions are spaced apart along the direction of mating, the first and second contact portions being configured to come into roll-face contact with the counterpart object.

Contact having two contact portions with their central lines in one plane

A connector to be detachably fitted with a connecting object such as a flexible printed circuit board or flexible flat cable, includes a plurality of contacts each having a contact portion adapted to contact the connecting object, a housing arranging and holding therein the contacts and having a fitting opening into which the connecting object is inserted, and a pivoting member rotatably or pivotally mounted on the housing. According to the invention, an auxiliary member having an engaging unit for engaging the pivoting member is mounted on the pivoting member at its predetermined position. With the aid of the auxiliary member, the pivoting member can be easily rotated or pivotally moved.

Connector

A fixture for a floating connector is to be mounted on a substrate and has at one end a connection portion to be connected to the substrate. The two fixtures are used in the floating connector including a plurality of contacts, an insulator fixing the contacts therein and having flanges, and a housing covering the insulator and fixing the contacts therein. The fixtures each include at the other end an anchoring bent piece adapted to engage the flange of the insulator to prevent the insulator from floating upwardly to an excessive extent. The floating connector using the fixtures is able to completely prevent the contacts from being buckled or deformed to an excessive extent when the floating connector is being fitted with or removed from a mating connector.

Floating connector with a fixture to limit vertical movement of the connector

An electrical connector consists of a plug connector and a receptacle connector to be fitted. An insulator is supported only by plug contacts each provided between second and third fixed portions with an elastic portion having at least one snaked portion so as to be floating in a housing. The shape of the second contact portion of each of the plug contacts is substantially in the form of a plate-shaped piece so that the second contact portion of the plug contact and the first contact portion of a receptacle contact are caused to contact each other in line contact at one location, and the elastic portion is arranged within a range from a position below the second contact portion to a position below the insulator. The electrical connector thus constructed is superior in resistance to vibration, and achieves space-saving and floating of the insulator.

Electrical connector

Portion of an electric connector

An electrical connector consists of a plug connector and a receptacle connector to be fitted. An insulator is supported only by plug contacts each having an elastic portion between second and third fixed portions so as to be floating in a housing. The elastic portion is so positioned that its upper curved portion is at the same height as a second contact portion and its lower curved portion is at the same height as the lower end of the insulator. The distal end of a first contact portion of a receptacle contact is folded back toward a first connection portion to provide a third contact to contact the elastic portion so that the first contact portion and the third contact portion of the receptacle contact and the second contact portion and the elastic portion of the plug contact are caused to contact each other in line contacts at two locations. The electrical connector thus constructed is superior in resistance to vibration, and achieves space-saving and a reduced overall height less than 5 mm and further the floating of the insulator.

Electric connector

A connector includes a required number of contacts, a housing, and a pivoting member. The contacts are substantially H-shaped and each includes at least a contact portion, a connection portion, a fulcrum portion, a connecting portion and a pressure receiving portion. The urging portions of the pivoting member are pivotally moved between the connection portions and the pressure receiving portions to bring the contact portions of the contacts into contact with a connecting object. The housing has a ceiling portion covering the contact portions of the contacts, and an upper wall covering the pressure receiving portions. The pivoting member includes an actuating portion, the urging portions, anchoring holes, and a cover portion for covering tail portions of the contacts upon pivotal movement of the pivoting member. The connecting object can be inserted into the connector with a slight force and dust proofing property can be improved.

A connector for memory cards includes a connector body having side walls on both sides and a rear wall. The side walls are formed over their length with card receiving portions to meet shapes of side edges and the number of the memory cards to be used. The connector further includes card identification terminals made of a springy metal strip arranged in a plurality of steps in inner surface of one of the side walls, identification tabs arranged spaced from the card identification terminal prior to insertion of a card, for identifying an existence of an inserted card with the aid of the contact between the inserted card and the card identification terminal, and terminals suitably arranged on the rear wall for writing electronic information into cards and reading stored information from cards. Each of the card identification terminals includes a contact portion to contact the card, a fixing portion to be fixed to the connector body, and a connection portion to be connected to a board and further includes an engaging portion on an extension of the contact portion, which engaging portion engages an anchoring portion of each of insertion grooves formed in the connector body.
