An electrical connector comprising a housing provided on one of opposite end portions thereof with an opening through which a flat circuit device is inserted into the housing, a plurality of conductive contacts arranged on the housing for contacting with connecting terminals on the flat circuit device in the housing, and a shell member mounted on the housing and provided therein with a holding portion operative to hold the flat circuit device in the housing. A releasing portion extends from the shell member toward the outside thereof, and a connecting portion extends from the releasing portion in a direction perpendicular to a conductive contact arrangement and the holding portion extends from the connecting portion, so that a folded-back protrusion is constituted in a body in the shell member with the releasing, connecting and holding portions.
摘要:
An electrical connector including a housing provided thereon with an opening through which a flexible printed circuit board (an FPC) is inserted into the housing, a plurality of conductive contacts arranged on the housing, a conductive shell mounted on the housing for covering partially the same and provided with a holding member, and a movable lever, wherein the holding member comprises an arm portion extending from the conductive shell to the inside thereof, an engaging projection provided at an end of the arm portion for engaging with an engaging edged portion provided on the FPC inserted in the housing so as to hold the FPC, a pressure receiving portion extending from the engaging projection for receiving pressure from the movable lever and an indicating portion extending from the pressure receiving portion to take up selectively first and second positions for indicating a state of the holding member, and the indication portion taking up at least one of the first and second positions is able to be visually checked from the outside of the conductive shell.

An electrical connector including a housing provided with an opening through which a flat circuit device is inserted into the housing, a plurality of conductive contacts arranged on the housing, a conductive shell mounted on the housing for covering partially the same and provided with a holding member for engaging with the flat circuit device inserted in the housing to hold the same, and a releasing member formed in the housing with a first end portion thereof operative to be in contact with the holding member and a second end portion thereof operative to project from the inside to the outside of the conductive shell, wherein the releasing member is moved so that the first end portion thereof causes the holding member to be released from engagement with the flat circuit device inserted in the housing when the second end portion thereof is pushed toward the inside of the conductive shell under a condition wherein the holding member is put in the engagement with the flat circuit device inserted in the housing.
摘要:
An electrical connector including a housing having an opening through which an FPC is inserted into the housing, conductive contacts arranged on the housing for contacting with signal connecting terminals on the FPC, and a conductive shell member mounted on the housing and provided therein with a holding portion for holding the FPC inserted in the housing and a releasing portion for releasing the FPC from holding by the holding portion, wherein the holding portion extends into the housing from an end wall portion of the conductive shell member covering a side end portion of the housing to engage with the FPC and the releasing portion is movable in an operating direction intersecting a direction of arrangement of the conductive contacts and provided thereon with an engaging projection for engaging with the holding portion to release the same from the engagement with the FPC.
摘要:
A digital convergence correcting device effecting convergence correction by using convergence correcting data stored in a memory which includes an address fixing device which, in the case where convergence correcting data are insufficient, reads out in succession the correcting data corresponding to the last horizontal scanning line for the portion lacking in the data so that the correcting data are used repeatedly, and which, in the case where convergence correcting data are excessive, only necessary convergence correcting data are used.
摘要:
A convergence correcting apparatus is used in a projection television receiver including a CRT having an aspherical fluorescent screen and a projection lens apparatus which is attached to the display screen of the CRT and has aspherical plastic lenses. In the digital convergence correcting apparatus, a digital memory stores digital correction data corresponding to correction values of convergence adjustments points indicative of a plurality of points on the display screens divided in the horizontal and vertical directions. A multiplexer reads out predetermined digital correction data from the digital memory and time sharingly multiplexes. At least one digital/analog converter receives the time sharingly multiplexed data from the multiplexer and generates an analog signal. Sample and hold circuits extract a predetermined correction signal from the analog output of the digital/analog converter and sample and hold them. The convergence correcting apparatus is driven in accordance with the respective correction signals held by the sample and hold circuits.
