A multipole electrical plug-in connector includes a plug-in connector housing and a mounting block. The plug-in connector housing has a housing base that extends perpendicular to a longitudinal axis of the plug-in connector housing. The housing base has insertion openings. Contact elements are respectively inserted through the housing base insertion openings. Each contact element has a contact portion that is connectable to a mating plug-in connector, a press-in portion, with a fir tree profile, that is pressed into the housing base insertion opening in which the contact element is inserted through, and a connection portion for connecting an electrical connection line. Each contact element further has a retaining portion between the press-in portion and the connection portion. The retaining portions of the contact elements are inter-lockingly fastened in the mounting block. A method for producing a multipole electrical plug-in connector of this type is provided.

An electrical contact a mating portion for mating with a mating contact. The mating portion has a contact portion and a retention portion. The mating portion has a mating portion bottom wall, a mating portion top wall and mating portion side walls. A respective mating portion side wall has an upper portion which extends beyond the top wall. The retention portion has a retention portion top wall, a retention portion side wall and a retention portion back wall. The retention portion back wall is configured to approximate the space provided between the mating portion top wall, the upper portion of the respective mating portion side wall, the retention portion top wall and a retention portion side wall. The retention portion back wall prevents damage or deformation of the retention portion as a force applied to the retention portion.

Electrical term finals and electrical connector assemblies for electrically conductive structures are described. An example electrical terminal has a terminal head and an electrical contact. The electrical contact extends from the terminal head and has a lengthwise axis and a spring finger contact. The spring finger contact is movable relative to the terminal head and has a cantilever portion and a contact portion. The cantilever portion extends away from the terminal head and away from the lengthwise axis of the electrical contact. The contact portion extends from the cantilever portion.

The present invention provides for an electronic isolator device for application in intrinsically safe environments having isolation and safety functionality and comprising: an isolator module (101), a safety module (100), and wherein the isolator module is arranged for removable physical/electrical connection to the safety module in at least two orientations/configurations (DO, Dl, Al, AO) relative to the safety module, wherein the electrical connection to the safety module in each of the at least two orientations/configurations serves to configure the electrical functionality of the safety module (100).

A locking connector system for releasably locking a first connector in mechanical engagement with a second connector. The locking connector system generally includes a first connector including a female coupler and a second connector including a male coupler, with the first and second connectors being adapted to mechanically connect to each other. The first connector includes an adjustable latch which selectively engages with a catch portion on the male coupler to lock the connectors together. The latch may be pressed downwardly, such as by use of a connected button, to release the latch from the catch portion and disconnect the connectors. The first connector is adapted to provide audible, visual, and tactile feedback to confirm when the latch engages with the catch portion.
