Description

Transformer protective capsule conventional, toroidal transformers, inductive components, power supplies and electronic circuits.

The present invention relates to a capsule Hard plastic housing, prior to mounting it until constitute a single body, conventional transformers, toroidal transformers, inductive components, sources of power and electronic circuits, being the degree of protection provided by the IP20 enclosure, so it protects according to norm against access to dangerous parts, against penetration of foreign solid bodies and against the penetration of Water. The assembled product forms the terminals of a single body connection to the transformer terminals and the user's network, a voltage indicator led, the product label and a mounting bracket for DIN rail mounting, the width being occupied in the DIN rail of only 54 millimeters, so achieves a reduction of space with respect to the capsules of conventional equipment and transformers, greater ease of installation and operation control through the led tension indicator

The present invention has its field of application in general for the electrical and electronic sector. In In particular, the capsule is intended to be used as a housing for mounting equipment, transformers inside conventional, toroidal transformers, inductive components in general, power supplies and electronic circuits in general.

Different types of capsules are known for  conventional transformers, inductive components, sources of power and electronic circuits, which are characterized for forming the housing by means of the encapsulation technique in resin by casting in molds that once polymerized the material withdraw The plastic housing is usually manufactured in one or several pieces that make up the entire body of the team. For the toroidal transformers known brackets and clamps for vertical or horizontal mounting. Some of these capsules They incorporate terminals. There are also presentations in capsules of cylindrical plastic

The disadvantages of these capsules against the proposed invention they consist in that the housing does not make up the connection terminals, the indicator led in one body voltage, product label and accessory support for DIN rail mounting, nor does it all occupy a DIN rail width of only 54 millimeters, so its oversize affects the loss of space on the one hand, which sometimes makes the installation itself is impossible and on the other it makes assembly difficult have to resort to supplementing additional supports for their anchor in the rail. In addition to the transformers for control, maneuvers and circuit breakers are used in the state of the technique conventional transformers, while in the invention  proposed toroidal transformers are used, with which get better performance, decrease in dimensions and pesos. Another difficulty with known capsules is  in the impossibility of accessing the terminals, because of the covers that cover them for safety reasons, having You must proceed to remove the cover to access the terminal. On the other hand, in the proposed invention the terminal cover presents perforations that, without compromising security, offer the possibility of accessing the terminals with a screwdriver, without Need to remove the cover.

Therefore, the present invention incorporates State of the art the following advantages:

-

Creating a capsule perfectly adapted to the space it requires for installation.

-

Significant space reduction, occupying only a width of 54 millimeters.

-

Ease of mounting on the DIN rail, to which it is attached only by means of clips.

-

Possibility of housing transformers toroidal inside, thus achieving better performance, decrease in dimensions and weights.

-

Possibility of operation control by the user and maintenance staff, thanks to the led voltage indicator that has built-in.

-

Possibility of accessing with a screwdriver to each of the terminals without removing the terminal covers, thereby improving control operations in maintenance works.

-

To the combine the product mounted in a single body all the elements that make up its constitution, is a final product of greater consistency and security than those who know each other.

Experience has shown that in this sector of the technique prevail the simple and effective solutions that They can be versatile and do not lead the final product, being Easy maintenance possible, parts supply deteriorated and serial production.

The transformer protective capsule conventional, toroidal transformers, inductive components, power supplies and electronic circuits is constituted to from a hard plastic box, which is the main body that It serves as accommodation. At the base of it is the DIN rail mounting bracket accessory, consisting of four legs with their corresponding holes for anchoring to DIN rail through screws. The box is equipped with grilles of ventilation to evacuate the heat generated inside by the active elements housed. Inside it has four perforations for securing equipment by means of flanges plastic. Two internal side rails meet conveniently located to house them, conveniently subjects, power supplies and electronic circuits. In the upper perimeter zone the box has at least four clips for fastening the lid that closes it. On the lid are the housings of the connection terminals. It has 8 terminals, each with its corresponding accommodation for the terminal connection and its respective nut. On these the screw is mounted and cable washer. The terminals are arranged in two rows of four one on each side of the lid, which allows differentiating the equipment entry and exit. The terminal cover is the cover that covers the terminals to prevent access for security reasons. Advantageously it consists of conveniently suitable perforations to allow access to the terminals with a screwdriver, without Need to remove the cover. It has numbering in relief (1, 2, 3, 4, 5, 6, 7, and 8) to indicate individually each terminal

It also advantageously has a hole upper for the accommodation of a voltage indicator led, in addition of a housing for the product label.

The degree of protection provided by the envelope is IP20, thus being protected against access to dangerous parts, against penetration of foreign solid bodies and against water penetration.

The assembled product conforms in one body the following elements: 8 terminal connection terminals, nut, screw and washer press wires, a led indicator of tension, a product label and a support accessory for DIN rail mounting occupying the assembly a width of only 54 mm, which achieves a reduction of space with respect to equipment capsules and conventional transformers.

The capsule is manufactured by plastic injection in mold and being composed of three main parts: Box, lid and terminal covers.

A thermal protector incorporated into the capsule protects transformers against overloads and heating excessive, providing maximum security to the user and avoiding possible fires in case of short circuits or heating Excessive transformer overload. This thermal protector acts in case of exceeding the temperature by opening the circuit breaker thermal composed of a bimetal the primary circuit of the transformer and leaving it to work, thus avoiding possible risks of the transformer burning out, and causing damage to things or to the users themselves.

The thickness of the protective elements used will depend on the need for protection and resistance, but in any case it will have to be adaptable to Different needs according to the uses.

Therefore, the versatility of the hard plastic with the lightness of it, the material being used with great shock resistance and extraordinary effectiveness for protection.

When the capsule of a design adapted to the different equipment that lodges, being able to be of the high and long determined in each case, although its width is that of the mentioned DIN rail, the adaptation to the different sizes and shapes of the mentioned equipment.

Alternatively, the capsule can be constructed with materials other than those described, provided they comply with its protection and safety function and with the regulations to respect.

Externally you can get different Aesthetics, colors and decoration.

For the best understanding of how much is left described herein are accompanying drawings in the that as a non-limiting example a case is represented practical implementation of the proposed capsule and its functioning.
