| 20100022104 | ELECTRICAL CONNECTING APPARATUS - An electrical connecting apparatus comprises a housing having a first recess extending in a first direction in a plane parallel to a board having a conductive portion to be connected to an electrode of a device under test and opened downward and a plurality of slits spaced in the first direction and extending in a second direction intersecting the first direction in the plane, wherein each slit communicates at one end portion in its longitudinal direction with the first recess and is opened at least upward, a plurality of plate-shaped contacts each electrically connecting the conductive portion to the electrode, having on the tip end side of the contact a tip end thrust to the electrode and a curved external surface, and arranged in the housing in a state of extending inside the slit from within the first recess with the external surface being on the lower side, and a probe holder arranged in the first recess and abutting on a part opposite the external surface of the contact so as to contact the external surface of the contact with the conductive portion. Accordingly, scraps scraped away by the tip end of the contact are prevented from reaching the board via the slit. | 01-28-2010 |
| 20100190361 | ELECTRICAL CONNECTING APPARATUS - An electrical connecting apparatus comprises a housing having a first recess extending in a first direction in a horizontal plane, opened downward, and having at least a backside inward surface and a plurality of slits spaced in the first direction and extending in a second direction intersecting the first direction in the horizontal plane, a plurality of contacts each arranged in the housing in a state of extending inside the slit from within the first recess and electrically connecting a conductive portion provided on a board to an electrode of a device under test, and a probe holder arranged in the first recess. The backside inward surface of the first recess includes an inclined portion inclined to both the horizontal plane and a vertical plane vertical to it in a state of being further to the front side towards the upper side, and each contact abuts on the inclined portion at least at part of the back end. Thus, slip of the contact against the conductive portion is reduced. | 07-29-2010 |

| 20080315893 | Contact and connecting apparatus - A contact and a connecting apparatus are provided to enable miniaturization and shortening and cost reduction in response to further miniaturization and finer pitch of inspection objects. The contact is one electrically for contacting a terminal of a wire and includes a one-side plunger portion, an other-side plunger portion, and an elastic deformation portion provided between the plunger portions. The elastic deformation portion is made of an annular and conductive elastic member integrally connected to the one-side plunger portion and the other-side plunger portion. The plurally arranged elastic deformation portions are disposed in a zigzag shape in the up-down direction with their adjacent heights different from each other. The connecting apparatus includes the plurality of contacts electrically contacting terminals disposed on an inspection object and a contact plate for integrally supporting the respective contacts to make the contacts contact with the respective terminals of the inspection object. | 12-25-2008 |
| 20090035960 | ELECTRICAL CONNECTING APPARATUS - The electrical connecting apparatus disclosed herein includes a frame member having a recess for receiving a device under test provided with a plurality of electrodes, a plurality of contacts provided in correspondence to the electrodes, a plurality of slots formed in the bottom portion of the recess of the frame member and arranged parallel to each other so as to receive the contacts such that the tip of each contact can abut the corresponding electrode, an elastic member disposed across the slots over the bottom portion within the recess to elastically hold the contacts, and a cap member mounted on the frame member and sandwiching the elastic body together with the frame member. | 02-05-2009 |
| 20090104795 | CONTACTS AND ELECTRICAL CONNECTING APPARATUS USING THE SAME - An electrical connecting apparatus uses a plurality of contacts each of which includes: a principal portion having an outer face curved and directed to a conductive portion of a base plate and received in a recess and a slit of a housing; a front end portion continuous to the front end side of the principal portion and projected upward from the slit so as to be relatively pressed against an electrode of a device under test; and a rear end portion continuous to the rear end side of the principal portion and located in the recess. The front end portion of each contact is projected upward from the slit by the dimension of the thickness of the front end portion or more than that and has an arc-shaped front end face extend in the longitudinal direction of the slit. | 04-23-2009 |
| 20100062662 | ELECTRICAL CONNECTING APPARATUS - An electrically connecting apparatus comprises a base member provided with slots penetrating in the plate thickness direction, contacts disposed within the slots so as to be able to contact electrodes of a device under test on the base member and for connecting the electrodes to an electric circuit of a tester, and an elastic member. The contacts has a fixed piece to be fixedly held on the base member within the slots for connection with the electric circuit, and a movable piece disposed within the slots for electrical connection with the fixed piece. In the fixed piece, a guide face for guiding the movable piece toward a contact position permitting the movable piece and the electrodes to contact is formed, and the movable piece is supported slidably on the guide face so as to receive elastic biasing force toward the contact position by the elastic member. | 03-11-2010 |
| 20100099277 | ELECTRICAL CONNECTING APPARATUS - An embodiment of an electrical connecting apparatus comprises an electrical insulating plate, an elastic plate made of an electrical insulating material arranged on the electrical insulating plate, a sheet-like conductive plate arranged on the elastic plate, and first and second contacts. The conductive plate comprises a hole area having at least one first hole portion allowing the probe tip portion of the first contact to abut to the conductive plate and a plurality of second hole portions not allowing the probe tip portions of the second contacts to abut thereon regardless of whether or not overdriving acts on the contacts. | 04-22-2010 |
| 20100120299 | CONTACT AND ELECTRICAL CONNECTING APPARATUS - A contact type electrical connector includes a first plunger in contact with one member; a second plunger in contact with another member and electrically connected to the first plunger, whereby the two members are electrically connected through the first plunger; a cylindrical support member for slidably and elastically supporting the first and second plungers with a connection portion of the first plunger and a connection portion of the second plunger overlapping and electrically connected; and a compression coil spring surrounding the outer peripheries of the first and second plungers with the connection portions thereof supported by the cylindrical support member and brought into contact with a spring receiving portion of each of the plungers so as to urge the plungers apart. | 05-13-2010 |
