摘要:
A sensor system includes a plurality of sensor bodies arranged aligned and adjacent to each other, each of said sensor bodies being connected to an electric cord including at least a signal line via a connector. Each connector has a power feed terminal, and a detachable fitting for electrically connecting the power feed terminals of the connectors is provided between the connectors. The power supplied to the connector of any of the sensor body through the power feed line in the electric cord is distributed to the power feed terminal of another sensor body through a row of connectors. By this configuration, the number of power feed lines for the overall system can be significantly reduced, and common bodies not distinguished for the main and sub bodies can be used as the sensor bodies, whereby the cost can be reduced and inventory management can be facilitated. Further, when any of the sensor bodies fails, it is possible to simply exchange the failed sensor body only, while maintaining the use of the electric cord that has been used.

A protective conductor clamp having a mounting leg for mounting the clamp on a support rail and a contact rail that is connected electrically conducting to the mounting base and is provided with at least one conductor connection. The mounting base has shaped sections for holding a spring element for bracing the mounting base in the support rail. The shaped sections are formed by recesses in two parallel-arranged side walls of the mounting base, between which the spring element is inserted.

An assembly for mechanically mounting and providing electrical connections to overcurrent protection devices having first and second male power plugs includes a non-conductive main structural support member having a plurality of plug passageways formed therein and one or more load busbar modules mounted thereon and also including a plug passageway formed therein, to enable the male electrical plugs to mate with sockets disposed in a conductive line busbar member mounted on said support member and with a socket disposed in a load busbar member included in each load busbar module. Each load busbar module includes a non-conductive housing and a releasable cover within which is mounted the load busbar member. A printed circuit board substrate is preferably also mounted to said support member to provide a support surface for auxiliary signal clip connectors disposed on one side of the substrate. Additional passageways enable auxiliary contact terminals that are preferably also included on each overcurrent protection device to extend through the substrate. Clip connectors disposed on the substrate are used to make electrical contact to the auxiliary terminals. Each set of sockets and clips are shaped and dimensioned to mate with the power plugs and alarm contact terminals of a plug-in circuit breaker or fuse module.

A signal input unit transmits detection signals derived from sensors such as switches, limit switches, or pressure switches to a programmable controller by means of serial transmission. A signal output unit transmits control signals from the programmable controller to control apparatuses such as solenoid-operated valve manifolds, indicator lamps, and buzzers by means of parallel transmission. The signal input units and the signal output units are integrated with each other into one unit and a number thereof is changeable. Further, an intermediate section and an end block are integrally assembled to the signal input units and the signal output units to construct a signal input/output apparatus.

A connector for an electric apparatus has a case and a base which are engaged to each other or integrally formed. The base has an elastic hook and a latch formed integrally on its bottom surface for engaging both edge parts of a rail so as to mount the connector removably to the rail. The case has side surfaces extended from the lower edges to provide extended members for covering both side surfaces of the elastic hook for providing protection against damage when the connector is accidentally dropped. Protrusions may be provided on the bottom surface of the base between the extended members and the elastic hook for limiting twisting deformation of the elastic hook. The bottom surface of the elastic hook has a curved portion for relieving any impact force that may be damaging.

This device includes a fastening catch disposed in an insulating housing (2), the fastening catch including two relatively sliding pieces (6) and each piece (6) exhibiting a hook (12) intended to allow latching on the support rail (4). A central hole (38) substantially perpendicular to the direction of movement of the sliding pieces (6) of the fastening catch is made in the housing so as to allow access to the fastening catch from the top of the housing, and in the latched position of the hooks (12), an edge running transversely with respect to the direction of movement of the hooks of each piece (6) is located in line with the central hole (38).
摘要:
An internal bus connector device is provided for use in the terminal block of an electrical power and signal distribution system, wherein the connector device includes a thin support plate that extends parallel with the support rail of the system and that carries a plurality of rows of pins each of which includes a pair of orthogonally arranged portions that extend parallel with and normal to the support plate, respectively. The pin portions that extend normal to the support plate are adapted for connection with the circuits of an associated printed circuit board, and the pin portions that extend parallel with the support plate are connected with conductors on the terminal block or with corresponding terminals of an adjacent terminal block mounted on the same support rail.
