Embodiment Construction
[0033] The plug-in module 14 according to the drawing comprises a housing, wherein the housing is accommodated within an overvoltage protection element, for example a varistor. Plug contacts and guide pins or coding pins known per se are formed in the lower region.
[0034] The end side 3 of the plug module 14 has an actuating surface 5 which is inserted into the joint 1 . Corresponding joints are located in the region of the top side 2 of the plug module 14 .
[0035] A hook-shaped locking lug 6 is provided at the lower end of the actuating surface, which forms an extended section of the joint 1 .
[0036] The stop surface 7 of the stop lug 6 forms an angle with the surface of the actuating surface, preferably less than 90°.
[0037] To improve handling, the operating surface 5 has a surface structure 9 .
[0038] In order to reduce the pressure exerted on the actuating surface 5 to release the locking connection, in the region of the joint 1 a groove inside a joint is for...

The invention relates to a pluggable device combination for protection against surges, comprising a socket-like U-shaped lower part for accommodating at least one plug-type module (14) accommodating a surge protection element, wherein latching means acting between the plug-type module and the socket-like lower part are provided which comprise, on opposite end sides (3) of the plug-type module (14), latching tabs which are formed on a hinge joint (1) under pre-stress and each engage in an associated latching cutout on the plug-type module, wherein the latching connection can be released by pressure being applied to the hinge joint on the end sides of the plug-type module. According to the invention, the respective hinge joint (1) is located in the transition region between the upper side and the respective end side of the plug-type module, wherein the hinge joint merges with an actuating face (5) pointing towards the socket-like lower part. Formed on the lower end of the actuating face is a hook-shaped latching tab, whose latching face (7) encloses an angle of less than 90 degrees with the actuating face. Finally, the U limbs of the lower part each have a hook-shaped, recessed latching cutout (8), which is designed to be substantially complementary to the latching tab.
Description
technical field [0001] The invention relates to a pluggable device assembly for overvoltage protection. Background technique [0002] Surge protectors of the prior art are in many cases designed as a pluggable assembly comprising a lower part and a plug-in module. [0003] Connecting clips for contacting the electrical conductors and corresponding recesses for the plug-in modules to be inserted are provided in the lower part. In addition, the lower part receives elements which surround one or more plug contacts of the plug-in module in order to obtain the desired mechanical and electrical contacting and the plug-in module is held accordingly in the lower part. [0004] There are real overvoltage protection elements such as spark gaps, varistors, gas arresters, etc. inside the plug-in modules. In many cases, the lower part is formed as a U-shaped body, wherein the open legs of the U-shaped body surround the plug modules laterally and the plug modules rest on the connecting ...
