The front terminal includes a front contact-point portion that wipes off foreign material adhered to a terminal surface of a plug terminal. The rear terminal includes a rear contact-point portion that contacts the terminal surface wiped by the front contact-point portion. The socket terminal also includes a movable portion between a circuit-board connection portion and circuit board. The movable portion cancels a reduction in impedance of at least the front terminal and rear terminal for a transmission signal flowing from the circuit-board connection portion connected to the circuit board. This can provide a socket terminal allowing the rear contact-point portion to contact the terminal surface from which foreign material has been wiped off, and allowing impedance mismatching at a terminal transmission path to be eliminated; and to provide an electric connector including the socket terminal. | 02-12-2015 |
20150044915 | Connector and Terminal - A terminal of a connector includes two contact points, that is, a front contact point and a rear contact point. An angle formed by a line extending from an upper end of a rear terminal portion to the rear contact point and a direction in which the connector is inserted and removed is smaller than an angle formed by a line extending from an upper end of a front terminal portion to the front contact point and the direction in which the connector is inserted and removed. Thus, the insertion force used to insert the rear contact point can be reduced. | 02-12-2015 |
20150031233 | Electric Connector - A connector terminal includes a front contact-point portion that wipes off foreign material by slidingly contacting a plug terminal and a rear contact-point portion that is conductively connected with the plug terminal. The front contact-point portion has a sliding edge that slidingly contacts the plug terminal. The rear contact-point portion includes a contact edge that is thinner than the sliding edge, has a sliding width that is less than that of the sliding edge, and is conductively connected with the plug terminal by passing a sliding path of the sliding edge. Therefore, it becomes less likely for the contact edge to contact foreign material adhered to a portion other than portions at the sliding path. Thus, conduction failure can be prevented. In addition, by providing the connector terminal, it is possible to provide a socket that can similarly prevent conduction failure caused by foreign material. | 01-29-2015 |
20150024620 | Electric Connector - A socket terminal includes a front connection portion that comes into contact with a plug terminal, in which a recess having an inner wall is formed in a contact surface that comes into contact with the front connection portion. The front connection portion is locked on the inner wall by coming into contact with the inner wall when moving in a direction in which the plug terminal is pulled out from the socket terminal. The front connection portion also includes a contact edge that wipes impurities off the contact surface. An electrical connection between the socket terminal and the plug terminal can be maintained by locking the socket terminal on the inner wall even with an application of vibrations in directions in which the plug terminal is inserted and pulled out. Since the contact edge can remove the impurities, the electrical connection between the terminals can be stabilized. | 01-22-2015 |
20140349526 | Connector - Provided is a connector in which a decrease in contact pressure due to the shape degradation of the pressing portions does not occur even if the operation of rotating the pressing member is repeated. Since the connector main body has, at the rear end, supporting portions that rotatably support the pressing portion, the pressing portion rotates while butting the rear ends of the movable pieces and the supporting portions so that the rear ends of the movable pieces are pushed up by the pressing portion, the butting of the pressing portion and the supporting portions is contact between synthetic-resin components, this eliminates the pressing portion being cut off due to contact with the supporting portions even if the rotation of the pressing member is repeated, and hence the shape degradation of the pressing portion can be prevented. | 11-27-2014 |
20140342614 | CONNECTOR - A connector is provided to sufficiently absorb the displacements of a plurality of connection objects with respect to a substrate even when the plurality of connection objects are connected. Two movable housings are formed by separate members that can move relative to each other, thereby absorbing the displacements of two mating connectors connected to the respective movable housings by each of the respective movable housings. This can sufficiently absorb the displacements of the mating connectors relative to a substrate. | 11-20-2014 |
20140187098 | Connector - A connector is configured such that elastic deformation of a movable section of each of terminals in the width direction is regulated by a recess within a specific range, thereby preventing the movable section from elastically deforming in the width direction to an excessive extent, even if the movable section of the terminal is subject to the effect of vibration, for example, due to being used in an engine room of a vehicle, and avoiding a short circuit between adjacent terminals or breakage of the terminal in an effective manner. | 07-03-2014 |
20140134883 | Electric Connection Terminal and Connector Including the Same - When a second junction portion of a terminal is pressed in the opposite direction of the direction of contact with a mating terminal, a first junction portion attempts to be displaced relatively in the direction of contact with the mating terminal as compared to the second junction portion while in a of state contact with the mating terminal, and accordingly, contact pressure of the first junction portion as to the mating terminal increases. Thus, after the mating terminal comes into contact with the first junction portion, contact pressure of the first junction portion as to the mating terminal is not reduced even when the mating terminal comes into contact with the second junction portion. | 05-15-2014 |
20140099828 | CONNECTOR - A connector which, when two contacts contact a connection object at positions different from each other in the insertion/extraction direction of the connection object, suppresses deflection of the connection object without increasing a pressing member size. The connector configured so, when the pressing member is rotated to a closed position, a pressing plate is brought into surface contact with the other thickness direction surface of a flexible circuit while pressed by a pressing member pressing portion, and a range including the contact positions between the flexible circuit and first and second contacts is pressed from the side of the other thickness direction surface of the flexible circuit via the pressing plate, so one thickness direction surface of the flexible circuit is brought into press-contact with the first and second contacts. Deflection of the flexible circuit is suppressed by the pressing plate, and the pressing member size need not be increased. | 04-10-2014 |
20140069716 | RESIN MOLDED PRODUCT AND METHOD FOR PRODUCING SAME - A resin molded product for reducing the external force applied to a first element from each electroconductive member due to a pressure of a resin at the time of molding, when each of the electroconductive members and the first element are insert-molded with the resin, and a method for producing the same.

20130157519 | CONNECTOR - A connector which can absorb thermal expansion and contraction of a substrate, or positional deviation of the substrate, and which enables the male and female connectors thereof to be fitted to each other where the male and female connectors are inclined to each other. A male terminal of a male connector, and a female terminal of a female connector are slidable relative to each other when in contact with each other. The male terminal and the female terminal are rotatable relative to each other about a contact point when in contact with each other, and hence the male terminal and the female terminal can be attached and detached to and from each other at an arbitrary rotating position. | 06-20-2013 |

20120164893 | ELECTRIC CONTACT AND CONNECTOR USING THE SAME - When a male side contact is inserted into a female side contact, female side contact portions in the female side contact press a plurality of male side contact portions in the male side contact, and each of the male side contact portions is displaced in a thickness direction of the male side contact while contacting the female side contact portions so that a contact area between the contacts can be sufficiently ensured. When the contacts are connected to each other, a feeling of the female side contact portions, together with each of the male side contact portions, being displaced in the thickness direction of the male side contact can be obtained. Further, the contacts engage with each other by the displacement of each of the contact portions so that movement of the male side contact in a direction opposite to its insertion direction can be regulated. | 06-28-2012 |
20120142226 | TERMINAL FOR ELECTRICAL CONNECTION AND CONNECTOR USING SAME - An electrical connection terminal arranged such that when the amount of displacement of one of a first contact portion and a second contact portion increases, a decrease in the contact pressure of the other contact portion is effectively suppressed, and a connector in which the electrical connection terminal is used. Between first and second elastic pieces and a fixed piece, a third elastic piece is provided such that when one of a first contact portion and a second contact portion is displaced in the direction of contact with a mating terminal, the amount of displacement of the other contact portion in the direction of contact with the mating terminal becomes smaller than the amount of displacement of the other contact portion in the insertion and removal direction of the mating terminal. Connection reliability by two-point contact may be improved. | 06-07-2012 |

When the press member is rotated in one direction, respective contacts are pressed toward the object to be connected by the press member and, when the press member is rotated in the other direction, the press of the respective contacts by the press member is cancelled. A rotation fulcrum of the press member is provided between one and the other ends so that when one end of the press member is pressed, the press member rotates in one direction and, when the other end of the press member is pressed, the press member rotates in the other direction. | 04-19-2012 |
20110194291 | STROBE DEVICE - Each of electrode terminals is provided with an electrode connection section connected to an electrode of an electric discharge tube. When an exterior member is mounted on a housing, a concave section of the exterior member abuts on the electrode connection section of the electrode terminal, to displace the electrode connection section in a direction in which the electrode of the electric discharge tube is held therein. Thus, the exterior member is mounted on the housing so that connection between the electrode of the electric discharge tube and the electrode connection section can be completed.

20100224601 | LASER WELDING METHOD - When a laser beam is incident on a thin film, carbide generated by the heat of the beam is not ejected between respective metallic thin plates. In each of second conductive sections of a metallic thin plate, a slit extends from a welding position to the end of the second conductive section. The second conductive sections are respectively welded to terminals by making the laser beam incident on the respective welding positions of a substrate for the thin film. Thereby, when the beam is incident on a resin, the resin is carbonized by the thermal energy of the laser beam and the resin carbide is ejected from the welded portion, and the carbide is discharged to the outside from the lower end of the second conductive section via the slit of the second conductive section. Thereby, the carbide is not ejected between the adjacent second conductive sections. Consequently, lowering of the insulation resistance between the respective second conductive sections due to the carbide is prevented. | 09-09-2010 |
20100159749 | CONNECTOR - A connector prevents a terminal from short circuiting when the terminal is elastically deformed with movement of a movable housing. The length in the width direction at one end of each terminal is larger than the length in the width direction at the other end, so the distance between the terminals at the other end is larger than the distance between the terminals at one end, thereby preventing adjacent terminals from contacting each other when movable terminal portions are elastically deformed. | 06-24-2010 |
