20090163065 | CONNECTOR - The invention provides a connector enabling a dead space of a substrate to be reduced while maintaining connection strength. For this purpose, H-shaped contacts comprise holding means permitting pushing portions of a pivoting member to be pivoted between pressure receiving portions and connection portions of the contacts. When an actuating portion of the pivoting member is moved toward a fitting opening of a housing, the pushing portions are pivotally moved and their axes of rotation are moved to achieve their compact rotation, thereby bringing contact portions of the contacts into contact with a connecting object. The substrate is formed with a notch into which the connector is fitted to be connected to the substrate. Fixtures are provided at both longitudinal ands of the connector and both or either of the fixtures is provided with an extending piece integral therewith or separate therefrom, extending substantially perpendicularly to the substrate, thereby limiting a rotated angle of the pivoting member upon it being opened. | 06-25-2009 |
20090149088 | MICROCONTACT, METHOD FOR PRODUCING THE SAME AND ELECTRONIC COMPONENT - A microcontact according to the invention is less than 10 mm in length and composed of a conductive basis material, a base surface treatment layer formed thereon, and an upper surface treatment layer, and includes a contact portion, a terminal portion, and an intermediate portion formed over its entire circumference with exposed oxide surfaces of the base surface treatment layer. The exposed oxide surfaces are formed by irradiating the front and rear surfaces of the contact with laser beams at respective predetermined inclined angles to remove the upper surface treatment layer and simultaneously to oxidize the narrow base surface treatment layer exposed by the removal of the upper surface treatment layer. In this manner, the exposed oxide surfaces can be formed with a high accuracy in a simple manner for stopping solder rise at a predetermined position when the terminal portion of the microcontact is jointed to a substrate by soldering. | 06-11-2009 |
20090130881 | CONNECTOR - A connector to be detachably fitted with a connecting object, includes a required number of contacts, a housing, and a pivoting member acting upon the contacts to bring them into contact with a connecting object. In case of having many contacts, at least one contact is provided with an extended portion at a tip of its pressure receiving portion to extend toward its connection portion, and instead of a pushing portion of the pivoting member acting upon the contact, the pivoting member is provided with an engaging rod to engage the extending portion of the contact. The contact is arranged at an optional position so as to prevent the pivoting member from being warped. The contacts are arranged in a single row, or alternately arranged to be staggered. With the connector thus constructed, the pivoting member is not damaged when pivotally moving after the connecting object has been inserted to achieve a stable electrical connection even with very small pitches of contacts and very thin walls of the housing. | 05-21-2009 |
20090068860 | CONNECTOR DEVICE - A connector device to be used with a flexible printed circuit board including a connector. The flexible printed circuit board has on its front and rear surfaces ground patterns, signal patterns and phase inversion signal patterns arranged such that the signal pattern and the phase inversion signal pattern are arranged between the two ground patterns, and has a ground layer between the front and rear surfaces and exposed portions located at predetermined positions and reaching the ground layer. The connector has first and second contacts of two kinds. The first and second contacts are arranged in one and the same inserting hole of the housing such that their contact portions are opposite to each other. When a pivoting member has been pivotally moved, the first and second contacts come into contact with the corresponding ground, signal and phase inversion signal patterns on the flexible printed circuit board and the members at the predetermined positions enter the exposed portions so as to contact the ground layer, thereby achieving a miniaturization of the connector and high speed transmission of signals. | 03-12-2009 |
20090047836 | CONNECTOR - The invention has an object to provide a connector | 02-19-2009 |
20090017645 | CONNECTOR - A first contact and a second contact are inserted into one and the same inserting hole of a housing so that contact portions of the first and second contacts are facing to each other. The first contacts each include the contact portion at one end and a connection portion at the other end. The second contacts each includes a first piece having the contact portion at one end and a pressure receiving portion at the other end, a second piece having connection portion at an outer end, and an elastic jointing-portion for jointing the first piece and the remaining end of the second piece. A pivoting member includes an actuating portion, pushing portions, and anchoring holes. The pushing portions are pivotally moved between the pressure receiving portions and the connection portions of the second contacts, during which pivotal movement, the axis of rotation of the pushing portions is moved with their pivotal movement to achieve their compact rotation. The second contacts are each provided on the second piece with a fixing portion in the proximity of the elastic jointing-portion. The connector constructed as above described prevents the contacts from being warped or deformed when the pivoting member is being pivotally moved, and achieves a stable electrical connection, a reduced overall height of the connector and a high density of the conductors. | 01-15-2009 |
20080299840 | CONTACT AND CONNECTOR USING THE CONTACT - An L-shaped contact includes a contact portion adapted to contact a mating object, a fixed portion to be fixed to a housing, and a connection portion to be connected to a connecting object, and a hole formed in a bent portion between the fixed portion and the connection portion. When the contact is fixed to the housing, the contact is inserted into the housing by pushing an end face of the hole. The L-shaped contact ensures a stable contacting surface area for being pushed by a jig and enables to bear a heavy-electric current to pass therethrough without adversely affecting miniaturization of a connector and extremely narrow pitches of the conductors. | 12-04-2008 |
20080214050 | ELECTRICAL CONNECTOR - An electrical connector to be detachably fitted with a mating connector, including a plurality of contacts, a housing for arranging and holding the contacts, and a shell covering the housing and forming with the housing a fitting opening for the mating connector. The shell has at least one engaging piece, and the housing has an anchoring portion at a location corresponding to the engaging piece to cause the anchoring portion to engage the engaging piece, thereby restraining the housing from being displaced in the direction opposite to the fitting direction upon fitting with the mating connector. Even being miniaturized, the electrical connector is securely positioned relative to the mating connector when fitting with it, and the housing is securely prevented from being displaced upon the mating connector abutting against the housing, thereby completely preventing any defective connection. | 09-04-2008 |
20080214031 | ELECTRICAL CONNECTOR - An electrical connector includes a plurality of contacts to be connected to a cable, a housing for arranging and holding the contacts, a shell dividable into two shells covering the housing and having a holding device for holding the cable, and an insulating member covering the shell. One of the shells is provided with anchoring portions and the other shell is provided with engaging portions so that when both the shells are fitted with each other, the anchoring portions and the engaging portions are engaged with each other to bring both the shells into electrical continuity with each other. Therefore, the shells can be securely held together to achieve reliable electrical continuity between the shells, and at the same time grounding between the cable and the shell and between the shells themselves can be achieved. | 09-04-2008 |
