Abstract: An electrical connector includes a main housing, an inner housing assembled in the main housing, and a plurality of conductive terminals of which each has a fastening arm molded in the inner housing, a contact arm and a touching arm perpendicular to the contact arm. The contact arms are apart arranged along a transverse direction in front of the inner housing. The touching arms are apart arranged along a longitudinal direction at one side of the inner housing. In use, the touching arms of the conductive terminals are elastically against and further pressed downward by a circuit board to realize electrical connection with the circuit board. It is rather short-time and convenient for mounting the circuit board to the electrical connector. Moreover, the touching arms of the conductive terminals are easily removed from the circuit board for the convenience of replacing the electrical connector when it doesn't work.

Abstract: An opener and a buffer table for a test handler are disclosed. The opener includes an opening plate, a plurality of pin blocks forming pairs, and at least one or more interval retaining apparatus for retaining an interval between the pin blocks forming a pair. Each of the pin blocks is movably coupled to the opening plate, and includes opening pins for releasing a holding state of a holding apparatus that holds semiconductor devices in a carrier board. Although semiconductor devices to be tested are altered in size and a carrier board loading with the semiconductor devices is thus replaced, the opener does not need to be replaced, thereby reducing the replacement cost and the waste of resources.

Embodiments of the present invention may also accommodate the effective implementation of a low cost filter pin connector. An integrated shield ring may create an EMI doghouse with a metal ring that attaches onto a bulkhead board mounted connector that is bonded to a circular chassis ground plane on a printed wiring board (PWB) assembly.

Abstract: A module retention and electromagnetic interference (EMI) cage has a substantially flat, rectangular metal frame with retaining clip portions and EMI-shielding contact fingers. The frame has surface-mount legs to facilitate surface mounting the cage to the circuit board. An array connector is mounted on the circuit board within a central region of the cage. An electronic module can be inserted or plugged into the cage in conjunction with connecting the module to the array connector. As the module is inserted into the cage, the module resiliently deflects the EMI-shielding contact fingers. At approximately the same time as the connector of the electronic module mates with the array connector, the retaining clip portion mates with a portion of the housing to retain the module in this position.

Abstract: In a connector for connecting a connection object having a locked portion, a movable member is provided so as to be movable in a predetermined direction between a connecting position and an ejecting position together with the connection object. A cam mechanism is coupled to the movable member and selectively maintains the movable member at the connecting position or at the ejecting position. A first engaging member is held by the movable member and is rotatable in a rotating direction. The first engaging member has a locking portion to be engaged with the locked portion in the predetermined direction when the first engaging member is located at a predetermined angular position. A braking device is coupled with the first engaging member to brake the first engaging member in the rotating direction.
