[0119] One in the Fig.The third embodiment of the electrical device shown in Figures 10 to 14 comprises a housing with at least one housing part (111, 125) and a cover part 104. The cover part 104 is pivotally mounted on the housing and is releasably connected to the housing by means of a locking means 101, preferably by clip connection.

[0120] The locking means 101 can be inserted into a slot-shaped recess in the housing part 125. For this purpose, the locking means 101 has two opposing grooves, in particular guide grooves (108, 110). The guide grooves (108, 110) span a common plane. Preferably, the housing part 125 extends at least partially in this plane.

[0121] The locking means 101 has a connecting portion 115 and a fastening portion 112, each extending transversely to an extension direction of the guide grooves (108, 110). Preferably, the connecting portion 115 and the fastening portion 112 are arranged perpendicular to each other. Preferably, the fastening portion 112 extends parallel to the housing part 125.

[0122] The connecting section 115 and the fastening section 112 are designed to be elastically deflectable relative to one another. For this purpose, the locking means 101 has a slot-shaped

[0123] Recess 116 extending parallel to the direction of extension of the guide grooves (108, 110). Preferably, the recess 116 is arranged between the guide grooves (108, 110). Preferably, the recess 116 extends through the common plane of the guide grooves (108, 110). Thus, the distance between the guide grooves (108, 110) is elastically variable.

[0124] The fastening section 112 has a projection 114 facing the housing part 125. The housing part 125 has a recess 103, which is preferably designed as a bore. The projection 114 can be inserted, in particular clipped, into the recess 103. The connection of the projection 114 to the recess 103 limits the mobility of the locking means 101, at least in the direction of extension of the guide grooves (108, 110).

[0125] The fastening section 112 is designed to be elastically deformable in a direction transverse to the direction of extension of the guide grooves (108, 110).

The housing part 125 projects into the guide grooves (108, 110) and delimits the locking means 101 at the guide grooves (108, 110) in the transverse direction to the direction of extension of the guide grooves (108, 110), in particular in all transverse directions to the direction of extension of the guide grooves (108, 110). The end region of the fastening section 112 facing away from the guide grooves (108, 110) is thus elastically deflectable relative to the end region of the fastening section 112 facing the guide grooves (108, 110).

[0127] To connect the locking means 101 to the housing part 125, the locking means 101 is inserted into the slot-shaped recess in the housing part 125. In doing so, the fastening section 112 deforms elastically, so that the fastening section 112 only touches the housing part 125 with the projection 114. As soon as the projection 114 reaches the recess 103 during insertion, the fastening section 112 springs back to its original shape. The projection 114 is connected to the recess 109 in a form-fitting and force-fitting manner. The fastening section 112 touches the housing part 125 along its entire length, in particular the length transverse to the direction of extension of the guide grooves (108, 110). Advantageously, the projection 114 is designed as a rounded cylinder that can be inserted with a precise fit into the recess 103 designed as a bore.

[0128] The locking means 108 has a first nose portion 113, which has a bevel 105, in particular a threading bevel for the cover part 104. The cover part has a second nose portion 106, which has a bevel 117, in particular a threading bevel for the locking means 101. Preferably, the first and second nose portions (113, 106) are arranged facing each other.

[0129] When the cover part 104 is closed, the first and second nose sections (113, 106) touch each other. For this purpose, the first and second nose sections (113, 106) each have a contact area. Preferably, the respective contact area forms an angle with a clipping direction of the cover part 104 that is less than 90° but greater than the angle between the respective threading groove (105, 117) and the clipping direction.

[0130] Preferably, the locking means 101 has a third nose portion 107 arranged between the first nose portion 113 and the guide groove 108. When the cover part 104 is closed, the second nose portion 106 contacts the locking means 101 between the first and third nose portions (113, 107).

[0131] Preferably, the electrical device has two similar locking means (108, 110), into each of which a wall section of the cover part 104 can be clipped.

[0132] In a further embodiment not shown, the third embodiment has features of the first and / or second embodiment, such as the joint receptacle 32 with the bearing section 31 and the joint section 3 with the pin 30, the cover part 52, the insertion guide part 12 and the groove 15 for the rating plate 6, the operating part 62 and / or the recess 53 for a mating connector part 56.
