Protection device for a plug-in connection

A protection device for at least one component of a releasable plug-in connection between a plug and a socket, which socket is disposed, at least partially, on or in the housing of the electronics unit, the protection device comprising:

• a first half shell and a second half shell, wherein the second half shell is at least partially complementary to the first half shell, and wherein the first half shell and the second half shell are configured as to define an internal volume when assembled together and to at least partially surround at least the plug;
• a first passageway and a second passageway, each defined in a wall formed by the first and second half shells in assembly and configured to enable passage of the plug, or the plug and at least a portion of a cable attached to the plug, into the internal volume;
• a securement member configured to releasably secure the protection device to the housing by form and force interlocking with a portion of the housing such that the plug-in connection meets the impact and mechanical shock requirements of an ATEX, IEC or NEC explosion protection standard, and wherein the securement member is included in at least one of the first and second half shells;
• and
• an assembling member configured to releasably assemble the first and second half shells together,
• wherein the first passageway is defined in a region of a wall on a side opposite the securement member, and wherein the second passageway is defined in another region of the wall and extends at an angle perpendicular to a plane parallel with the securement member.
