An apparatus and a method for optically linking at least two AC and DC low voltage cascading power grids connecting at least two intelligent support boxes (ISB) each powered by two distinct AC standard power grid and separately powered by DC low voltage power grid with each grid is further linked by a cascading segments of optical cable grid, enabling two way control, operate and report electrical activity through plug in wiring devices (PWD) for supporting DC and AC plurality of connected/attached loads.

A socket body (1) comprises a socket space (3) which is delimited by a socket wall (2), extends along a center axis (M), wherein the socket space (3) has a socket opening (22), which is surrounded by an end surface (6). A notch (4) extends through the socket wall (2) at an angle (α) to the center axis (M) such that a spring lug (5) is formed, which spring lug (5) is bent into the socket opening (3). The notch (4) has a right-hand portion (7) and a left-hand portion (8), wherein a center plane (ME) extends through the center axis (M) centrally between the two portions (7, 8). As seen from the outer side of the socket body (1), an upper surface (16) of the notch (4) intersects exclusively the lateral surface (11) of the socket wall (2), but not the end surface (6).

A physiological signal monitoring device includes a sensing member and a transmitter connected to the sensing member and including a circuit board that has electrical contacts, and a connecting port, which includes a socket communicated to the circuit board and a plurality of conducting springs. The sensing member is removably inserted into the socket. The conducting springs are electrically connected to the electrical contacts and the sensing member for enabling electric connection therebetween. Each of the conducting springs is frictionally moved by the sensing member during insertion of the sensing member into the socket and removal of the sensing member from the socket.

A power connector includes a housing having a mating slot at a front having terminal channels holding power terminals between the slot and the corresponding side of the housing. Each power terminal includes a plate extending from the slot through a rear of the housing to an exterior of the housing for termination to a corresponding power element. The power terminal has a contact array of contacts discrete from and coupled to the plate. Each contact has a plate interface electrically coupled to the plate and a bus bar interface configured to be electrically coupled to a corresponding rail of the bus bar. The contacts are arranged along a corresponding side of the slot for interfacing with the bus bar.

A floating connector and an insulating base thereof are provided. The insulating base includes a ring-shaped frame, a floating carrier spaced apart from the frame, and a plurality of buffer arms that connect the floating carrier to the frame. The frame includes two elongated strips arranged on two opposite sides thereof, and has a buffer opening defined by an inner edge thereof and corresponding in position to the floating carrier. Each of the buffer arms has a first buffer segment connected to the frame and a second buffer segment that curvedly extends from the first buffer segment to the floating carrier. When the floating carrier receives an external force, the first buffer segment and the second buffer segment of any one of the buffer arms absorb the external force respectively along different directions, so that the floating carrier is moved relative to the frame along the different directions.
