An industrial indicator light with straight plug-in wire entering technology may include a wiring module, a current bar, a wiring spring, a mounting shell and a push block, both the current bar and the wiring spring are clamped within the wiring module, the wiring module is to be inserted into the mounting shell, and the push block is to be located above the wiring spring and being capable of moving downward to press against the wire spring such that one end of the wire spring is spaced apart from the current bar. In the present example solution, straight plug-in wire entering is adopted to facilitate on-field wiring.

An electrical device arrangeable in a row with other electrical devices includes: a first bus section contactable with a further electrical device arranged on a first side of the electrical device; a second bus section contactable with a further electrical device arranged on a second side of the electrical device facing away from the first side; and a contact device, to which an electrical assembly is connectable, and which includes a contact element for establishing an electrical connection between the first bus section and the second bus section when the contact device is not connected to the electrical assembly, and, when the contact device is connected to the electrical assembly, is displaced in order to disconnect the first bus section and the second bus section from one another.

An electronic-component-equipped terminal block includes a terminal block including first and second through holes provided in a front wall; an electronic component including a component body first and second leads; and an electrically insulating attachment assistance tool. The attachment assistance tool includes a base portion arranged outside a housing such that a rear surface thereof abuts against the front wall; and first and second insertion portions protruding from the rear surface of the base portion to be thereby inserted into the first and second through hole, respectively. The attachment assistance tool is provided with a first passage portion through which the first lead is inserted, and a second passage portion through which the second lead is inserted, and a receiving portion that receives and accommodates a rear portion of the component body is provided at a front-side position.

Herein is described a n electrical earthing device formed from a sheet of material and comprising: an earthing device connector portion, for connection of the earthing device to a component to be earthed; and an earth cable connector portion, for connection to an earth cable. A first part of the earth cable connector portion is disposed in relation to a second part of the earth cable connector portion so as to define a clamping mechanism. In use, an earth cable positioned between the first and second parts is retained in position and maintained in electrical contact with the clamping mechanism by resilient biasing between the first and second parts of the clamping mechanism.

An electric connector comprises a male terminal and a female terminal. The male terminal comprises a first connecting member, a first elastic member, a first wire opening, and a first connecting opening. The first elastic member comprises a first elastic arm extending towards the first connecting member and being configured to be inserted through the first wire opening, and the first connecting member is configured to be inserted through the first connecting opening. The female terminal comprises a second connecting member, a second elastic member, a second wire opening, and a second connecting opening. The second elastic member comprises a second elastic arm extending towards the second connecting member and being configured to be inserted though the second wire opening, and the second connecting member is configured to extend through the second connecting opening. The first connecting member and the second connecting member are in electrical contact with each other.

A quick connect terminal assembly for attaching a conductor to an electrical circuit includes a terminal which can be attached to an electrical circuit. A retainer engages the terminal which defines a conductor space between the retainer and the terminal. The conductor space insertably receives an end of a conductor. The retainer is biased toward the terminal to compress the conductor between the terminal and the retainer. Each of the retainer and the terminal is comprised of an electrically conductive material to facilitate electrical communication between the conductor and the electrical circuit. A sheath is positioned around the terminal and the retainer to inhibit electrical communication between the conductor and external objects.

A “safe grounding apparatus” (SGA) for safely grounding or neutralizing the electrical conductors for permanent magnet motor (PMM) powered artificial lift systems and methods of practicing the same are disclosed. The SGA of the present invention ameliorates some of the dangers associated with PMM's. Methods of shorting, grounding, testing and monitoring the electrical conductors of a permanent magnet motor in order to safely manipulate the conductors are also disclosed.

A spring-loaded terminal connection having a busbar and a clamping spring, which has a clamping arm, wherein the clamping arm extends towards the busbar and has a spring clamping edge for clamping an electrical conductor and wherein the busbar has a busbar clamping edge for fixing the electrical conductor to be clamped, wherein the busbar clamping edge has a radius less than or equal to 0.2 mm.
