    [0001] TECHNICAL FIELD OF RECYCLABLE ELECTRICAL EQUIPMENT DESCRIPTION The present invention relates to a recyclable electrical equipment pole. The electric poles referred to herein, which can be used in particular at low, medium or high voltage, comprise an active part, electrical connections connected to the active part, and an external body in which the active part and the electrical connections are retained, the connections opening out of the body.
    [0002] In most cases, the body is constructed of a thermosetting material, such as epoxy, polyurethane, vinylester or unsaturated polyester, or even an elastomer such as polyester, EPDM or silicone. Since transformation into a solid state is irreversible, these materials are not recyclable. The increasing demands for making recyclable industrial products lead to the search for new designs of these electrical poles. Thus, it has been proposed to construct external bodies made of thermoplastic materials (for example, in document WO 2011/0095980 or WO 2012/006172), which, being constituted by a reversible network, are capable of softening or to melt when heated, allowing reuse.
    [0003] But even these improved designs are not sufficient to allow easy recycling, since it is still necessary to separate the different components of the poles, constructed of different materials, and ensure that during the usual grinding before recasting and recycling, impurities will not remain in the recycled product. However, since a good mechanical behavior of the poles is sought during their service, the assembly of the various constituents is made with great cohesion, and the active part and the connections are in practice inseparably embedded in the outer body, which is overmolded. on them. The connecting means consist of a strong adhesion of the body to certain surfaces, for example those of the ceramic vacuum bulbs, or to an encapsulation of pieces of complex shape in the body, that is to say a imprisonment of these parts in the body, by cohesion of form, with or without adhesion of their matter. With the invention it is sought to obviate these recycling difficulties, by proposing a pole of electrical equipment whose components are easy to separate in an impeccable manner, that is to say without leaving impurities in neighboring rooms. In a general form, the invention relates to a pole of electrical equipment, comprising an outer body, an active part retained in a housing of the body, and connections through openings of a wall of the body and opening out of the body and in the housing, characterized in that the connections are composed of portions having constant sections or tapering towards the housing, and are fixed in the openings by detachable stop means. The electrical connections can thus be extracted by simple movements, translation, once the stop means has been removed. No destruction, for example by machining, cutting or grinding, is necessary to effect the separation of the constituents, so that the separation of the different materials is perfect, without leaving impurities in the components (body, active parts, metal connections ), to recycle or more generally to reuse; once they are separated. The extraction of the stop means is the same by simple disassembly that involve no damage to the body.
    [0004] The body is advantageously made of a thermoplastic material, so that it can be recycled in case of damage, contrary to the usual designs, where the components of the pole are in any case indémontables. The stop means may advantageously be screws engaged in the connections, and the bores are perpendicular or oblique to the connections.
    [0005] The screws are an example of stopping means perfectly removable. In a particular design, a screw can also be used to attach the active part, and its rod then passes through one of the electrical connections to stop it. This design is particularly simple. Some of the stop means can occupy holes through the wall of the body, and thus retain the corresponding connections, blocking them relative to the body. The stop means are then normally accessible from outside the body to disassemble. They can also be used to hold the active part, immobilizing it in the housing. The stop means may also be internal to the body and arranged in the housing, and be removable through an opening of the latter.
    [0006] These different possibilities are compatible with good cohesion of the active part and connections with the body, using only a small number of stopping means. Another improvement, allowing at the same time a simple manufacture of the body of a good cohesion with the connections, without however compromising the facility of later extraction of the connections, appears if the body is overmolded on the connections. Another aspect of the invention relates to the ease of disassembly of the active part. The housing of the body can thus advantageously comprise a passage opening of the active part, with a regular section or flaring towards the opening, which will extract the active part of the body simply by pulling it, once the stop means will have been dismantled. The sliding of the active part out of the housing will be facilitated if for example it is provided with sliding collars protruding at its periphery, which make it adhere to the housing by a small area. According to certain other improvements, the connections comprise a cylindrical outer portion, preferably of revolution, and an inner portion provided with at least one hole in which one of the stop means is respectively engaged, the inner portion having a smaller section than the outer portion for each of the connections. The outer portion of regular shape allows junctions easy to other equipment and avoids the irregularities of electric field, and the inner portion assigned to the connections with the other components of the apparatus, may have an irregular shape, in particular to obtain a nesting with the surrounding material of the outer body, which promotes the cohesion of the pole by counteracting the pivoting movements of the connections, but only allowing those in the direction of extraction or insertion, that is to say the axial direction of the openings .
    [0007] In particular, the inner portions may include grooves extending in an axial direction of the openings, the grooves being filled with body material. The material of the body can easily fill these grooves if for example the body is overmolded on the connections: the nestings obtained are rigid with respect to pivoting movements of the connections, without hindering the extraction of the connections when the pole will be disassembled. One of the connections may still have its inner portion in the form of a tongue. The invention will now be described more fully in its various aspects, characteristics and advantages in connection with the following figures, which illustrate a non-exclusive embodiment of others: FIG. 1 is a general view of the sectional pole; Figure 2 illustrates in section the separated outer body, and Figures 3 and 4 illustrate the separate electrical connections. Figure 1 shows an exploded pole of electrical equipment according to the invention. An external body 1 houses an active part 2, here belonging to a vacuum interrupter, an upper electrical connection 3 and a lower electrical connection 4 connected to the active part 2 and giving on the outside. The body 1 (FIG. 2) has a generally cylindrical shape (of square, polygonal or preferably round section), with a central recess 5 opening downwards to receive the active part 2, an upper lateral opening 6 for containing the upper connection 3, and likewise a lower opening 7 to contain the lower connection 4. The housing 5 is also cylindrical, preferably of revolution even if the section can take any other form. The upper connection 3 comprises (FIG. 3) an outer cylindrical portion 8, advantageously of revolution, and an inner portion 9, in the form of a flat tongue and whose thickness face carries a groove 10; the inner portion 9 is preferably of the same section as the outer portion 8 or of smaller section than the outer portion to further facilitate the extraction. The end of the tongue is traversed by a fixing hole 11.
    [0008] The lower connection 4 also comprises an outer cylindrical portion 12, advantageously of revolution, and an inner portion 9, in the form of a flat tongue and whose thickness face carries a groove 10; the inner portion 9 is preferably of the same section as the outer portion 8 or of smaller section than the outer portion to facilitate the extraction. The end of the tongue is traversed by a fixing hole 11 and an inner portion 13 of smaller section, and which is provided with a longitudinal groove 14 and a tapped hole 15 in the radial direction. The inner portion 13 is preferably of the same section as the outer portion 12 or smaller section to facilitate extraction. The equipment also comprises an upper screw 16, intended for fixing the upper connection 3 and the active part 2, whose head is established in a seat 17 dug at the top of the body 1, and whose rod passes through the upper part of the body 1, the fixing hole 11, and is screwed into a tapping established at the top of the active part 2. When the upper screw 16 is in place, it therefore prevents the active part 2 from falling to the bottom of the housing 5 and out of the body 1, and it also prevents the extraction of the upper connection 3 out of the upper opening 6. A lower screw 18 is engaged in the tapped hole 15. The screws 16 and 18 are preferably perpendicular to the openings 6 and 7 , and therefore to connections 3 and 4, without it being necessary. The active part 2 comprises in particular a cylindrical casing 19, provided with two flanges 20 in projecting strips, which bear slidingly on the internal face of the body 1. The active part 2 represented here being a vacuum interrupter, there is still a mechanism internal control 21, housed at the bottom of the body 1, which will be actuated by a separate element not shown outside the pole. A lower cover 22 is screwed to the bottom of the body 1 on an opening 26 of the housing to close the housing 5; alternatively, the closure can be performed by a membrane. Another element of the active part 2 is a movable contact 27. The lower screw 18 passes through a bore of the movable contact 27 and thus connects it to the lower connection 4. It is internal to the housing 5, but accessible from the outside, its head, by which it can be disassembled, being directed towards the opening 26, and located in an enlargement 28 of the housing 5, which allows to insert a tool through the opening 26.
    [0009] The characteristics of the invention relate above all to the possibility of easily separating its constituents so as to be able to recycle them. It is easy to proceed by dismounting the screws 16 and 18. The connections 3 and 4, being composed of portions whose section is constant or tapers towards the inside of the openings 6 and 7, can then be extracted without effort or with a minimum force of the body 1, and the active part 2 can on its side be easily extracted through the opening 26 once the lower cover 22 disassembled, pulling it down, thanks to the reduced friction it exerts against the body 1 by the collars 20 of small area. No tearing or destruction of material is to be feared, which guarantees the perfect separation of the different materials once the components have been dismantled. This design is compatible with a good dielectric strength, important reliefs being avoided, since the electrical connections 3 and 4 and the screw 16 are contained in the openings and holes of the body 1 barely flush with its surface. The screw 18 is internal to the body 1. Good mechanical cohesion is also guaranteed despite the ease of separating the various elements, since the active part 2 remains firmly in the body 1 and the nesting (clearly represented in the Figure 2) of the material of the body 1 in the grooves 10 and 14 prohibits most of the movements of the connections 3 and 4 and in particular the pivoting, only displacements in the direction of extraction remain possible, and they alone are therefore arrested by the screws 16 and 18. The cohesion of the electrical pole is therefore about as good as that of existing equipment, despite the lack of embedding, encapsulation or strong adhesion between the different parts. The manufacture can be accomplished by overmolding the body 1 on the connections 3 and 4: the thermoplastic material of the body 1 then enters the grooves 10 and 14, forming tabs 23 and 24, shown in Figure 2. Alternatively, it would be possible to build the body 1 by molding separately, then to assemble the electrical connections 3 and 4. The active part 2 is then installed and the screws 16 and 18 tightened. The electrical equipment may in particular be a low, medium or high voltage switchgear, such as a circuit breaker, a switch, a recloser, contactor, disconnector, or other. Some suitable thermoplastic materials for constructing the body 1 are polyethylene, high density polyethylene, polyethylene terephthalate, polypropylene, polystyrene, aliphatic or semi-aromatic polyamide, polyphthalamide, polyarilamide, or any other thermoplastic or TPE (thermoplastic elastomers) injectable. Many other embodiments are obviously possible. This is how the stopping means can be more numerous. Several screws 16 or 18 can be proposed to hold the connections 3 and 4 and the active part 2 with more force. The stop means, such as the screws 16 and 18, can pass through the wall of the body 1, perpendicularly or obliquely, or, if internal, such as the screw 18, be oblique or perpendicular to the connections 3 and 4. There is obviously a large choice of section shapes for the inner portions 9 and 13, to oppose the pivoting of the connections 3 and 4, such as flats, dovetails, etc., and in general all sections irregular shapes.
    [0010] Once the active part 2 and the connections 3 and 4 extracted from the body 1, the constituents become unusable can be recycled directly, and the others reused without precaution, since no damage was done during disassembly, including no part of components has been removed and remains on a neighboring component, which may require additional sorting. The guarantee of not damaging still usable components and therefore of being able to use them is an important advantage of the invention.
