Protected plug

An arrangement comprising a pin-side plug and a socket-side plug for electrical connection to the pin-side plug said pin-side plug comprising:

• a pin-side plug housing with a plug base and a plug wall,
• an electrically conducting contact pin with a free pin end and a base-side pin end for fastening the contact pin to the pin-side plug housing, and
• a protective element, which is designed to be electrically insulating,
• wherein the protective element is arranged on the pin-side plug housing at a distance from the contact pin,
• and
• said socket-side plug comprising:
• a socket-side plug housing with a plug base and a plug wall, and
• a socket, which is arranged in the socket-side plug housing and is designed for receiving the contact pin in the connected state,
• wherein the socket-side plug housing has a receptacle for receiving the protective element in the connected state
• wherein the protective element has a first portion, which is oriented along a first direction, and a second portion, which is oriented along a second direction and is intended for providing reinforcement with respect to a deformation of the first portion,
• wherein the plug wall has at least one or two parallel wall surface(s) on its inner surface, facing the contact pin, or on its outer surface, facing away from the contact pin, which parallel wall surfaces are arranged lying opposite one another with respect to a center axis extending along the contact pin, from the base-side pin end in the direction of the free pin end, and/or are arranged in each case at an equal distance from the center axis, and
• wherein the plug wall has an arcuate portion, which connects the two parallel wall surfaces to one another in an arcuate manner and wherein the protective element is arranged with respect to the plug wall in a plane that is defined by the center axis and by an arc center point of the arcuate portion, and wherein the protective element is arranged in this plane midway between the parallel wall surfaces.

A socket-side plug and a pin-side plug for an electrical connection with each other, said pin-side plug comprising:

• a pin-side plug housing with a plug base and a plug wall,
• an electrically conducting contact pin with a free pin end and a base-side pin end for fastening the contact pin to the pin-side plug housing, and
• a protective element, which is designed to be electrically insulating,
• wherein the protective element is arranged on the pin-side plug housing at a distance from the contact pin, and
• wherein said socket-side plug comprises:
• a socket-side plug housing with a plug base and a plug wall, and
• a socket, which is arranged in the socket-side plug housing and is designed for receiving the contact pin in the connected state,
• wherein the socket-side plug housing has a receptacle for receiving the protective element in the connected state, and
• wherein the socket is arranged in a conductor element, and wherein the receptacle for receiving the protective element extends into the conductor element, and wherein the receptacle is arranged in the conductor element in such a way that the protective element is surrounded by the conductor element exclusively on its circumferential side, but not at its end face.
