A terminal block includes an insulative body, a conductive member, an elastic sheet and a pressing member. The insulative body has a receiving room therein and is formed with a pressing hole and a wire hole, which separately communicate with the receiving room. The conductive member is received in the receiving room and has a seat and a contact portion tilted up from the seat. The elastic sheet is received in the receiving room. An end of the elastic sheet is in contact with the conductive member. The pressing member is disposed in the pressing hole and capable of moving toward the receiving room to push another end of the elastic member. The pressing member has a placement slot. Each of two sides of the placement slot has a blocking wall.

An adapter for a housing opening in a housing of a splice block can include an adapter body that is movably coupled to the housing and includes a conductor passage. The adapter body can be selectively movable between a closed configuration and an open configuration, in which the conductor passage is, respectively, in and out of alignment with the housing opening.

A modular electrical bus system for a valve manifold has a communication module, a valve driver module, and a plurality of I/O modules each having a plurality of I/O fittings being both electrically and mechanically connectable together via a bridge member connecting adjacent modules. The bridge member has a housing with an interior for housing electronic components for memory storage or Wi-fi reception and transmission that is operably connected to a complementary electrical fitting constructed to be connected to an electrical fitting of a module of said electrical fieldbus system without adding extra length to said bank of modules of said electrical fieldbus system.

A light-emitting terminal block structure is provided. A lighting module includes a circuit board and a lighting component. An insulation body is combined on the circuit board and has an accommodating space, an insertion hole and an indication hole. The insulation body is formed with a notch at a side facing the circuit board, and the lighting component is located in the notch. A light pipe is disposed in the accommodating space and has a light-guiding end and a light-emitting end. The light-guiding end is oriented toward the light emitting element and spaced apart from the light emitting element by a distance. The indicator hole is exposed from the light-emitting end, and the conductive seat is combined in the accommodating space and has a resilient plate and a soldering leg soldered on the circuit board.

A vice-type terminal block for electrically connecting a pair of lugs by clamping them together. Each lug includes a barrel extending along an axis and a radially extending flange connected to the barrel. The flange has, on the opposite side to where the barrel is located, an electrical contact surface normal to the axis. The vice-type terminal block includes two opposing plates and a clamping system. Each plate includes a slot for receiving one of the lugs such that the flange of the lug is on one side of the plate, whereas the barrel is on the other side. The pair of lugs are supported such that their electrical contact surfaces face one another and are aligned.

An electrical terminal block with simplified switching operations, which can be produced in a cost-effective and time-saving manner.

The invention relates to a device for holding in position and placing in electrical contact (5) for a connection terminal of an electrical apparatus (1), arranged to hold in position and place in electrical contact at least two electrical conductors (7a, 7b), the device (5) comprising: a first retaining element (9a) having a first engagement portion (19a) arranged to engage, in a retailing position, with a first electrical conductor (7a); a second retaining element (9b) having a second engagement portion (19b) arranged to engage, in a retaining position, with a second electrical conductor (7b); and a clamping point (23) defined at least partially in the retaining position by the first engagement portion (19a) and the second engagement portion (19b).

A composite elastic wiring device includes a shell, an operating assembly and a connecting terminal disposed in the shell. The shell is formed with a wire hole. The operating assembly includes an operating member, a first elastic sheet and at least one second elastic sheet. One end of the operating member has a first abutting portion and a second abutting portion, another end of the operating member is disposed with a triggering portion outside the shell. The first elastic sheet and the second elastic sheet are stacked. The first elastic sheet and the second elastic sheet have a first pressing end and a second pressing end, respectively. The first and second pressing ends blocking the wire hole in order. A wire in the wire hole is pressed by the first elastic sheet and the second elastic sheet.
