Definitions

• Circuit breakers are used for these purposes, which can be installed coupled to differential current detectors, establishing the necessary connections by means of external interconnection cables between the respective devices.
• connection cables requires the use of cables covered with an insulating cover, which, however, does not ensure the insulation with due guarantee, since the cables are left without more protection than their coating, which can be damaged, with the consequent risk of discharges or short circuits.
• the differential current detecting devices are constituted by a structural assembly in which the assembly of the corresponding mechanisms is complicated, as well as the coupling of the joint between the parts that determine the respective outer casing.
• a housing intended for electrical appliances and in particular for said differential current detection devices is proposed, with which characteristics are obtained that satisfactorily solve those problems indicated above, providing essentially important advantages of a constructive and functional nature.
• This housing object of the invention consists of a socket and a cover, which determine the housing of the mechanisms of the apparatus, establishing the coupling between said elements by simple ion fitting and retention by engagement between respective crimping conformations, while in relation to the aforementioned assembly, a piece that is protruding towards one side is engaged frontally, which determines a prominent conformation that fits by the open front of the socket, being seized by a complementary piece that is included above in clamped fastening with respect to the walls of the socket and that determines the housings of the connecting bums, leaving the front piece with the possibility of a limited play of movement in the directions of insertion and removal, as that said part determines on the outside some flutes that extend partially along it, being prologized by the conformation of lace to the end of it, in which flutes are located open the external connection cables of the apparatus with the respective circuit breaker .
• the arrangement of the front piece allows its positioning to position the laterally attached circuit breaker, while with the subsequent movement of said part into the socket, the inclusion of the connecting cables in relation to the terminals of the circuit breaker is determined.
• a clamping cover is incorporated on the outside, which covers the cable housing grooves; while on the upper edge of the part that protrudes laterally, accessory inserts are incorporated to guide and fixation by means of a crimp button, from which projections come out of tabs that are placed on the terminals of the circuit breaker, sealing the access to them.
• the switch mechanism of said differential current sensing apparatus is arranged in a support that includes a tongue, by means of which the mounting of said support is established by insertion into a groove of defined groove in a side wall of the socket.
• a housing is thus obtained whose assembly is very easy to attach for the assembly, since all the connections are established by a simple fit between the component elements.
• connection with respect to the corresponding circuit breaker is in turn easily achievable, due to the mobility of the housing part of the connection cables; while for the mentioned connection, bare wires can be used, these being perfectly isolated in their housings, without any possibility that they could accidentally contact each other, or that an external contact with risk of electric shock could be established with them.
• this recommended housing is certainly of very advantageous characteristics, acquiring its own life of its own and preferential character of application in the devices for which it is intended.
• Figure 1 shows an exploded perspective of the partial assembly of the recommended housing formed by the socket, the cover, the housing part of the external connection cables and the complementary part determining the terminal housings.
• Figure 2 is a perspective view of the socket and the housing part of the external connection cables, in an opposite arrangement of said elements according to the correlative mounting position.
• Figure 3 is a perspective like that of the previous figure, with the elements coupled, with a partial cut in the socket having been made to appreciate the insertion therein of the housing part of the external cables.
• Figure 4 is a perspective of the part that can be incorporated to cover the access to the terminals of the application circuit breaker.
• Figure 5 is a perspective of the lock button of the previous piece.
• Figure 6 is a perspective in observation on the inside of an outer covering cover of the housing part of the outer cables.
• Figure 7 is a perspective of the cover of access cover to the terminals of the differential current detector in the recommended housing.
• Figure 8 is a perspective of the support of the switch mechanism incorporated in the housing.
• the object of the invention relates to a housing for a differential current detector that can be coupled to circuit breakers, such as the circuit breakers that are arranged in the power supply installations in control and safety functions.
• Said housing is constituted by a socket (1) that determines the housing for the mechanisms of the corresponding apparatus, a cover (2) that closes the entire housing being attachable from the top.
• the socket (1) determines at one end an open front, with respect to which a complementary piece (5) that determines the housings for the terminals is coupled, said piece (5) being incorporated into the assembly by means of coupling by coupling with respect to the socket ( 1), while the cover (2) establishes in relation to it a fastening by means of corresponding conformations (6) and (7) of elastic coupling.
• Said complementary piece (5) establishes the closing of the open end of the socket (1), leaving at the bottom an opening (8) uncovered.
• a piece (9) is coupled, which determines a prominent conformation (10), by which it fits into the opening (8) in the socket (1).
• That piece (9) is in the assembly arrangement frontally arranged in front of the housing, leaving laterally to the side, while in the insertion with respect to the socket (1) it is possible with a certain set of movement in and out in the opening (8).
• Said piece (9) has along the outer part ribs (11), which end in correspondence of respective through holes to the inner part, while at the other end they correspondingly extend along the prominent conformation ( 10), as seen in Figures 2 and 3.
• the arrangement of the mentioned part (9) in the assembly is such that it is in a position in front of the socket (1) and with the projecting part towards the side in front of a lateral area, where the application circuit breaker of the differential current detector housed in the recommended housing, so that the electrical connection between both devices It is achievable by bridging cables that are housed in the grooves (11), whereby said cables are perfectly insulated from each other, and can even be bare cables, since the separation of the grooves (11) effectively ensures the necessary insulation.
• the differential current detector and the application circuit breaker are incorporated in the installation on the same clamping rule, by means of the corresponding mounting conformations (12), such as those that the socket (1) has on the back, so that the cables for the connection that leave the differential current detector are arranged in the grooves (11) of the piece (9), moving it outwards to allow the circuit breaker to be placed in front of it and once the circuit breaker is placed in that position said part (9) is moved inwards, whereby the ends of the connection cables are to be correspondingly housed in the circuit breaker terminals, being only necessary to tighten the pressure screws of said terminals to ensure the connection.
• a cover (13) of outer covering is incorporated, which has rods divided into two flexible halves with the widened tip , as can be seen in figure 7, by means of which the fastening is established in the assembly by insertion in corresponding holes (10) of the piece (9).
• accessory parts (15) are also incorporated, as shown in Figure 7, which are arranged in the assembly on conformations (16), being secured in the installation by anchoring by means of a actionable button (17), as shown in figure 5, which is included by a hole (18) of the respective piece (15), said button (17) having toothed pins (19), by means of which by pressure it is engaged in a corresponding conformation (20) of the piece (9), thus being established an assurance that prevents disassembly.
• the pieces (15) have tabs (21) protruding from them from the rear, so that said tabs (21) are located in the assembly arrangement correspondingly above the handling accesses of the terminals of the coupled circuit breaker, establishing a protection seal with respect to the mentioned terminals.
