Description

Device for quick coupling between lid and electrical mechanism box.

This utility model refers to a device designed to perform quick coupling between cover and box of electrical mechanisms, specifically those mechanisms for command, connections and control in low and medium voltage electrical installations, coupling that is achieved by a clipping by means of a sliding element conveniently arranged.

One of the most outstanding features in current electrical installations, whether or not built-in, intended for low and medium voltage supply for homes, small businesses or industries, is the use of self-balancing and interchangeable electrical mechanisms, which allow, in the first place , change the use and purpose of the internal mechanism, such as that of a switch by a switch or by a socket or socket of data transmission line, for example, and secondly, carry out these operations of change of function, as well as other maintenance or repair work, quickly and simply by having easily attachable and detachable elements that facilitate the work, while ensuring perfect union and stability between its components, and especially between the lid and the box where these mechanisms will be housed and protected
electrical

The device object of the present invention offers a practical and simple solution, of economic execution and easy to use for quick coupling and guarantee the fixing and connection between cover and electrical mechanism box, as well as to allow easy opening and comfortable closing later.

It consists essentially of the device quick coupling cited in a clamp, by way of "clip", made from a suitable material flexibility and resistance, able to allow, once received your permanent way of opening what is necessary to hug around and below the screw head or the screws of fixing the box on the metal support frame or similar, remaining so that the lid is perfectly immobilized and fixed on the box, only the reverse displacement of the clamp or "clip" to separate of the corresponding screw and stop hugging it, so that the lid is loose and can separate and allow access to the interior of box.

This sliding clamp or clip will remain conveniently located inside an elongated housing, at one of whose ends is the through hole of the cover where the fixing screw to be attached will be accessible, conveniently threaded, the box with the frame. Once placed the screw will move the clamp or "clip", which will be placed around the body of the screw, by under its head, thus keeping the lid attached and held to the box. The "clip" offset in the reverse direction It will release the screw head and the cover can be separated.

Finally, Figure 21 explodes an explosion. practical application of the device, for quick coupling, In an electrical mechanism.

According to the drawings above reviewed, the device for quick coupling between the lid (1) and the box (2) of electrical mechanisms, consists of the special provision of a clamp or "clip" (3), slidable by the inside of some lateral grooves (4a) made in the surface housing (4) that has the cover (1) on its face superior, accommodation where the opportune one is also found hole (5) where the screw (6) will be properly arranged Fixing.

The clamp or "clip" (3) is made to from a material of adequate flexibility and strength, capable for this reason to carry out a permanent clipping action, without deform, and consequently, ensure the element's grip around which it has been placed to effect said clipping.

The mentioned "clip" (3) in general in "U" has two elongated and parallel legs (7) and a relatively circular widening (8), arranged in the area half of the legs (7), said widening being identical in both, so that the "clip" presents the proper widening so that, when displaced by the user with the help of a auxiliary tool (9) slide inside the slots (4a) and that it is essential when the cover (1) is loose.

When the legs (7) are located below the head (6 ') of the screw (6), at that time, the user can definitely screw the screw (6) tightly to the "clip" (3) and thus guaranteeing the ease of the lid (1) on the box (2) to which it will be strongly united.

It is presented as a variant of practical realization the "clip" (10), also provided with two parallel legs and equal (11), provided in the same central area of a widening (12), distributed between both legs, in diameter slightly higher than the head (6 ') of the screw (6).

Once the cover (1) is placed, the "clip" (10) until the parallel legs (11) are located below the underside of the head (6 ') of the mentioned screw (6), when the user will proceed to screw definitely the screw (6) guaranteeing the fixing of the "clip" (10) and the movableness of the cover (1).

Both in the embodiment described first, as in the embodiment variant described below, the "clip" in its two variants (3) and (10), will be perfectly located inside your accommodation (4), thanks to the area widening of the "clip" is inserted inside of the lateral grooves (4a) of said housing.

In figure 21 a exploding perspective of the electrical mechanism corresponding to a switch, with its actuation key (13), among others components, observing the position of the clips (3) located next to the box fixing screws (6) (1), indicating the movement of said "clips" with an arrow (3) to embrace and clip the corresponding screw (6).

Described sufficiently the object of the present invention, it should be noted that any variation in dimensions, shapes and finish, as well as materials used in the realization of the device that has been described, they will not alter the essentiality thereof, which is summarized in the claims following.
