20100290861 | METAL PLATE MEMBER FIXATION DEVICE INSTALLATION METHOD - A metal plate member fixation device installation method includes the step of preparing a barrel and inserting the front mounting portion of the barrel into a mounting through hole of a metal plate member and then bonding the barrel to the first metal plate member by a reflow soldering process, the step of providing a locking device formed of a lock screw and a cap and then sleeving a spring member onto the lock screw to force one end of the spring member into engagement with a retaining portion at the shoulder of the lock screw, the step of axially slidably coupling the cap of the locking device to the barrel to let the spring member be stopped between a step in the barrel and the retaining portion of the lock screw, and the step of releasing the pressure from the cap to finish the installation. | 11-18-2010 |
20110023680 | PCB CUTTER MODULE WITH DETACHABLE CUTTERS - A PCB cutter module is disclosed to include a base having a magnetically attractive worktable, a plurality of cutters detachably attached to the worktable and secured thereto by magnetic attraction at selected locations in selected directions subject to the design of the PC board to be cut. By means of magnetic attraction, the cutters are adjustably replaceably secured to the magnetically attractive worktable to fit different cutting requirements for cutting different designs of PC boards or different sizes of PC boards. | 02-03-2011 |
20110045915 | METHOD FOR THE FABRICATION OF A SCREW MEMBER FOR PLATE MEMBER FASTENER - A method for making a screw member for plate member fastener is disclosed to include the step of preparing a metal element subject to a predetermined size and then processing the metal element through a cold extrusion forging operation to form a head at one end, a connection portion at an opposite end and a shank between the head and the connection portion, the step of processing the connection portion through a thread rolling operation to form threads around the periphery, the step of processing the threads to form a stop end edge at one side in proximity to the shank, and the step of finishing the final product. | 02-24-2011 |
20110067219 | METAL PLATE MEMBER FIXATION DEVICE INSTALLATION METHOD - A metal plate member fixation device installation method includes the step of preparing a barrel, the step of bonding the barrel to one of two metal plate members to be affixed by a reflow soldering process, the step of providing a screw member and a cap and coupling the screw member and the cap tightly together, the step of preparing a spring member and sleeving the spring member onto the shank of the screw member and then inserting the screw member and the spring member into the barrel at the metal plate member, the step of axially slidably coupling the cap to the barrel to let the spring member be stopped between a step in the barrel and a part of the shoulder of the screw member, and the step of releasing the pressure from the cap to finish the installation. | 03-24-2011 |
20110070046 | METAL PLATE MEMBER FIXATION DEVICE - A metal plate member fixation device includes a barrel for bonding to a mounting through hole of a first metal plate member, a lock screw bolt inserted through the barrel for threading into a screw hole of a second metal plate member to lock the first and second metal plate members together, a cap affixed to the head of the lock screw bolt for gripping, a spring member sleeved onto the shank of the lock screw bolt and stopped against the heat of the lock screw bolt, and a stop washer positioned in an annular inside locating groove in the barrel around the shank of the lock screw bolt and stopped against the other end of the spring member for allowing axial movement of the lock screw bolt relative to the barrel within a predetermined range and for stopping against one end of the thread of the lock screw bolt to prohibit escape of the lock screw bolt from the barrel. | 03-24-2011 |
20110070049 | FASTENER - A fastener includes a barrel for fastening to a mounting through hole of a first metal plate member, a screw member inserted through the barrel for threading into a screw hole of a second metal plate member to joint the first and second metal plate members together, a cap molded on the screw member for holding the barrel temporarily on the inside by means of friction engagement between the barrel and the cap, a spring member sleeved onto the screw member and stopped between the shoulder of the screw member and an inside annular flange of the barrel, and a C-shaped retainer ring fastened to the shank of the screw member to prohibit falling of the screw member out of the barrel. | 03-24-2011 |
20110081218 | METAL PLATE MEMBER FIXATION DEVICE - A metal plate member fixation device includes a barrel for bonding to a mounting through hole of a first metal plate member, a lock screw bolt inserted through the barrel for threading into a screw hole of a second metal plate member to lock the first and second metal plate members together, a cap molded on the head of the lock screw bolt, a spring member sleeved onto the shank of the lock screw bolt and stopped against the shoulder of the lock screw bolt and an annular inside step of the barrel, and a compressively deformable annular stop member positioned in an annular inside locating groove in the barrel around the shank of the lock screw bolt for stopping against one end of the thread of the lock screw bolt to prohibit escape of the lock screw bolt from the barrel. | 04-07-2011 |
20110308065 | CAPTIVE SCREW INSTALLATION METHOD - A captive screw installation method includes the step of riveting a barrel to a panel frame, the step of coating a coating on the surface the barrel and the surface of the panel frame, the step of fastening a lock screw to a plastic knob and a spring member to the locks crew, the step of inserting the lock screw and the spring member into the barrel and then coupling the knob to the barrel. The barrel of the captive screw is riveted to the panel frame prior to coating, avoiding damage to the coating during installation. | 12-22-2011 |
