Patent number: 5971777Abstract: A physical/electrical media jack is configured for electrically coupling with a physical/electrical media plug. The jack includes a housing having an interior chamber communicating with the exterior through an opening. Positioned on opposing sides of the opening are a pair of blocking ridges each having an inside sloping edge. In one embodiment, dovetailed splines are positioned on the exterior surface of the housing for receipt in complementary keyways formed in the border frame of a PC Card or the casing of an electrical apparatus. The jack further includes a retractable access portion having an aperture formed therein for receiving a media plug. The second end of the retractable access portion is slidably received within the opening in the housing. Outwardly projecting from opposing sides of the retractable access portion at the second end are a pair of retention lips. The retention lips bias against the blocking ridges to prevent unwanted removal of the retractable access portion from the housing.Type: GrantFiled: November 21, 1997Date of Patent: October 26, 1999Assignee: 3Com CorporationInventor: R.

Patent number: 5967807Abstract: This invention is an "improved AC/DC electric adapter with the large and small plugs". The main body of the device consists of upper and lower casings; inside the box, there is an electronic converting circuit. In its upper casing, there is an indentation design to hold the large plug; in the large plug, there is a small plug with the rotary pins. The small plug pins can be rotated into the ordinary formation (with the shape of "11") or the two angled formations because there are the following internal designs: two insulating pieces with three guiding holes and push-up pieces (the latter can make the pins mesh with the three guiding holes). Therefore, the small plug pins can be used to draw current from the regular socket or angled pin socket. In addition, its electronic converting circuit can convert the AC into low voltage DC. So, the invention can be used indoors.Type: GrantFiled: August 20, 1997Date of Patent: October 19, 1999Assignee: Formosa Electronic Industries Inc.Inventor: Michael Wu

Patent number: 5964619Abstract: The electrical connector may include a housing, a contact, a secondary lock, a grommet, a backplate, a bolt, a contact removal tool, and a splash guard. The housing includes openings which receive the contacts. The grommets are positioned in cavities at the rear of the housing. The housing and backplate are designed so that the grommets are subjected to compressive forces in order to enhance the sealing characteristic of the grommets. As the contact is inserted, a locking tab engages an opening in the contact and prevents the contact from being removed from the housing. The secondary locks will increase the retention of the contact in the electrical connector. In addition, the secondary lock may include a feature which permits the partial insertion and retention of the secondary lock prior to insertion of the contact. The secondary lock also assures that the contacts have been properly inserted.Type: GrantFiled: August 10, 1998Date of Patent: October 12, 1999Assignee: Labinal Components and Systems, Inc.Inventors: Louis S. Pacini, Arun J. Shah
