Embodiment Construction

[0020] Figure 1 to Figure 4 The screw locks for the terminal blocks are shown respectively. Therein, the device comprises a body or shell-like part 1 made of an insulating deformable material, for example of plastic material. Formed in the body or shell-like part 1 is a vertically extending well 2, into which a screw 3 can be sunkly inserted, comprising a screw head 4, as in particular figure 2 with Figure 4 shown in . In order to ensure the automatic locking of the screw 3 or make the screw 3 inseparable, according to figure 1 with figure 2 In a first embodiment of the present invention, a striped structure 6 may be provided in the area of ​​the well wall 5 . Wherein, the stripe structure 6 is designed in such a way that the stripe structure 6 can be elastically deformed when the screw head 4 passes through, that is, during the screw-in process. That is to say, when the screw head 4 sinks into the shaft structure 2 , the stripe structure 6 is pressed back, wherein t...

Abstract

The invention relates to an arrangement for screw locking electric connecting terminals, comprising a body or a housing-like element (1) made of insulating, deformable material, preferably a plastic material, in which a perpendicularly extending duct (2) is integrally formed, into which a screw (3) including the head (4) thereof can be screwed in a sunken way. A profile (6) is provided in the region of the duct wall (5) for securing the sunken screw (3), said profile being elastically deformable when screwing in the screw (3) and while passing over the head (4), wherein the profile (6) is deformed back toward the inside of the duct for securing the screw (3) after passing over the head (4). According to the invention, the duct wall (5) is provided with a groove (8) integrally formed in the material, wherein the screw (3) or the duct (2) has a noncircular shape.

Description

technical field [0001] The invention relates to a screw locking device for an electrical terminal, said screw locking device comprising a body or shell-like part made of an insulating deformable material, preferably a plastic material In this way, a substantially vertically extending well-like structure is formed in the body or the shell-like part, and a screw can be sunkly screwed into the well-like structure, and the screw includes a screw head, wherein, in order to ensure that the sinking In order to lock the head screw, a striped structure is provided on the area of ​​the well wall, and the striped structure is elastically deformed during the screwing-in process of the screw and when the screw head passes through, wherein, for locking The striated structure of the screw returns to the shape inside the original well-like structure again after the screw head has passed through. Background technique [0002] Such screw locks for preventing the screws from locking themselve...
