Electrical connector

To well prevent a conductive contact from being peeled off with a simple structure, a rear end portion of the conductive contact to which a cable-shaped signal transmission medium is coupled is directly held by a contact engaging part. Even when an external force due to so-called flapping or the like is added from the cable-shaped signal transmission medium to the conductive contact, the conductive contact is well prevented from being peeled off. Also, a guide inclined surface for positioning the cable-shaped signal transmission medium is provided at the contact engaging part, and the cable-shaped signal transmission medium can be stably mounted along the guide inclined surface of the contact engaging part, thereby easily and accurately performing operations at the time of mounting, such as positioning.

Electric connector and manufacturing method thereof

An electrical connector including a housing having an opening through which a flat circuit device is inserted into the housing, conductive contacts arranged on the housing, a conductive shell provided with a holding member for engaging with the flat circuit device to hold the same, and a releasing member provided on the housing with a manipulatable portion and a pressing portion for engaging with the holding member, wherein the manipulatable portion is formed to be movable in a direction along which the conductive contacts are arranged and the pressing portion is operative to move for pressing the holding member so as to cause the same to disengage from the flat circuit device when the manipulatable portion is moved in the direction along which the conductive contacts are arranged under a condition wherein the holding member is put in engagement with the flat circuit device to hold the same.

Electrical connector with releasing member

To allow electromagnetic shielding regarding a connecting portion between conductive contacts and a main wiring board to be excellently achieved with a simple structure without impairing productivity, a fit-in holding member being rotated from a fit-in releasing position to a fit-in acting position to maintain a state where connectors fit in together by rotation is provided with a conductive cover part covering a connecting portion between a counterpart connector and the main wiring board when the fit-in holding member is rotated to the fit-in acting position, and the connecting portion is covered with the conductive cover part. Electromagnetic shielding of that portion is performed simultaneously with the time when both of the connectors fit in together, thereby eliminating an increase in the number of manufacturing processes. Also, the connection state at the connecting portion between a conductive contact and and the main wiring board can be clearly confirmed until the fit-in holding member is rotated to the fit-in acting position.

Electric connector and electric connector assembly

An electrical connector which comprises an insulated housing on which a first engaging portion is provided for engaging with a second engaging portion provided in a mating electrical connector, first contacts arranged in a predetermined direction on the insulated housing and operative to come into contact with second contacts provided in the mating electrical connector, a conductive shell for covering partially the insulated housing, and an aligning cover attached to the conductive shell and operative to cause end portions thereof in the predetermined direction to engage respectively with end portions in the predetermined direction of the mating electrical connector for aligning the insulated housing with the mating electrical connector when the first engaging portion is engaged with the second engaging portion, and with which the first engaging portion can be appropriately and smoothly put in engagement with the second engaging portion.

An electrical connector comprising an end portion of a flat circuit device which forms a connectively engaging protrusion on which a plurality of contacting terminals are arranged and a supporting board portion for supporting the connectively engaging protrusion, and first and second conductive shells having respectively first and second plate portions opposite to each other with the supporting board portion between, wherein the first conductive shell is attached to the supporting board portion with the first plate portion thereof covering directly a first surface of the supporting board portion and the second conductive shell is attached also to the supporting board portion with the second plate portion thereof covering directly a second surface opposite to the first surface of the supporting board portion, so as to hold the connectively engaging protrusion supported with the supporting board portion for causing the same to engage with a mating electrical connector.

An electrical connector comprising a manipulative lever operative to engage with a mating electrical connector, which has a body portion and a pair of end portions connected respectively with both ends of the body portion and supported respectively by a pair of supporting structures provided in a conductive shell covering partially an insulated housing, wherein each of the end portions of the manipulative lever comprises an elongated portion stretching to be bent from the body portion and a top end portion stretching further from the elongated portion so as to extend as a whole in a first direction from an end portion to a central portion of the insulated housing, the top end portion protrudes from the elongated portion in a direction perpendicular to an imaginary central axis of the elongated portion to form a stepped portion between the elongated portion and the top end portion, and a stopper member provided in the supporting structure engages with the stepped portion so as to prevent the end portion of the manipulative lever from getting out of the supporting structure when the end portion is shifted in a second direction opposite to the first direction.

An electric connector makes it possible to achieve downsizing excellently to improve electric connection reliability by preventing deformation when fitting to a mating connector. An engaging projection projecting is provided on an opening end edge of either an insulating housing or a conductive shell. An engaging hole into which the engaging projection is inserted is provided on the other opening end edge. The insulating housing and the conductive shell are fixed to each other in a direction orthogonal to the fitting direction by inserting the engaging projection into the engaging hole so that rigidity is largely increased. The fixation mechanism of the insulating housing and the conductive shell do not project inside the insulating housing so that it is possible to reduce the height and make pitches narrow.
