Title: Floating electric connector and manufacture thereof
Inventor: KOBAYASHI FUMIO
IPC: H01R13/73
Filed: 1994-06-10
Abstract: PURPOSE:To allow floating by integrally constituting a spring fitting and a connector. CONSTITUTION:A connector is inserted into an aperture P1 of a panel from the upper part. When the connector is inserted, a fixing part of a spring fitting comes in contact with the periphery of the aperture P1 and elastically deformed in the inside direction of the radius, and the periphery of the aperture P1 is snapped within a fixing groove 3A to complete fixing. The groove 3A comes in contact with the upper surface of the panel P and is electrically connected with an earthing pattern formed on the surface. A mating connector S is connected from the upper part and supported with a supporting part 4. When the connector S is a shield connector, a shield body is connected with the earthing pattern of the panel through the supporting part 4 and the fixing part 3 of a main body 1 for earthing. When the connector performs relative movement in the horizontal direction to the panel P, large floating is allowed by elastic deformation of the fixing part 3. More or less floating even in the supporting part 4 is allowable.

IPC: H03K3/353
Filed: 1986-06-27
Abstract: PURPOSE:To improve the control performance of a logic threshold voltage and a hysteresis voltage of the titled circuit and to attain the steep hysteresis characteristic by adding the 2nd control circuit controlling the potential of a signal internal output terminal using an external output terminal as an input source to a conventional Schmitt trigger circuit. CONSTITUTION:P-channel MOS transistors (TRs) 1,2 are turned on in the process that a signal input voltage VIN reaches a level V4a+Vt3, an H level is obtained at the signal internal output terminal 2a and an L level is obtained at a signal external output terminal 5a. Since P-channel MOS TRs 8, 18 are turned on even when the signal input voltage VIN exceeds the threshold voltage of an N-channel MOS TR 4 and reaches a value being a difference between a threshold voltage Vt1 of the TR 1 and a power voltage VDD, the signal internal output terminal 3a keeps the H level. When the signal input voltage VIN is higher than the voltage V4a of a connecting point 4a by the threshold voltage Vt3 of the N-channel MOS TR 3, the said TR 3 starts turning on.
