Embodiment Construction

[0019] With reference to the accompanying drawings, the electrical switchgear comprises a housing 10 substantially in the shape of a parallelepiped. The rear wall 12 of the housing 10 has a notch 13 into which the mounting bracket 5 will be inserted. The mounting bracket 5 itself is contained in, for example, a box, box or frame. In the embodiment shown, the mounting bracket 5 is a substantially horizontal DIN rail, the cross section of which is the well known hat shape with two opposing edges. The recess 13 is topped with a chute or jaw 11 into which the upper edge of the rail 5 can fit so that the device can be placed on the mounting rail 5 . Once the device has been placed there, the operator can still move it along the guide rail 5 and in particular position it precisely. Then, in order to fix the device, all that is required is to clip with the locking device according to the invention the bottom edge of the guide rail 5 which is in contact with the device.

Abstract

The device has a pawl (30) with a retaining unit (35) that cooperates with a complementary unit (45) arranged on a bolt (40) to maintain device in unlocked position. A helical compression spring (20)placed in a space formed between median part (44) and two lateral parts of the bolt maintains the device in locked position. Respective ends of the spring are supported against the bolt and pawl. An Independent claim is also included for an electrical switch appliance.

Description

technical field [0001] The invention relates to a bistable locking device for quickly locking low-voltage electrical switching devices such as contactors, circuit breakers, and contact circuit breakers on a mounting bracket. The invention also relates to a switch comprising such a locking device. Background technique [0002] As is known, electrical switching devices usually contain a locking system on their back so that they can be secured to mounting brackets, especially in panels or enclosures. Such a system is usually used to lock the device to a connecting rail comprising a part like a horizontal DIN rail, which is a hat-shaped part with two opposing edges and which is a standard size. This system has the advantage of being faster and more flexible than conventional locking systems using attachment screws on the plate, allowing the user to easily install the unit. Once the device is locked, electrical connections can easily be made. [0003] Typically, locking system...
