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 with adequate guarantee the insulation, 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 and of the connection terminals, establishing the coupling between said elements by means of a simple fit and the retention by hook between respective shaping conformations, while in relation to the mentioned set an "L" shaped piece is coupled, which is left with one of its branches coming out laterally and with the other housed branch in a lateral recess of the socket, with the possibility of a limited play of movement in the directions of insertion and extraction, determining said piece by both sides some ribs that extend along the entire inner branch and partially by the outer branch, in which are connected to the external connection cables of the device with the respective circuit breaker.
  • the mobile arrangement of the piece in "L" 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 is determined in relation to the terminals of the circuit breaker
  • clamping caps are incorporated by clipping, which cover the grooves of cable accommodation on the outside; while on the upper edge, accessory inserts are incorporated to guide and fixation by blocking by means of a crimping button, from which projection tabs are placed 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, whereby the support assembly of said support is established by insertion into a groove defined in a side wall of the socket.
  • a housing is thus obtained whose assembly is very easy to attach for the assembly, since all joints 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 in itself and preferential character of application in the devices for which it is intended.
  • Figure 1 shows a perspective of the recommended housing, without the support of the switch mechanism and with the housing of the external connection cables partially covered only by the corresponding covers.
  • Figure 2 is an exploded perspective view of the partial housing assembly formed by the socket, the cover and the housing part of the external connection cables.
  • Figure 3 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 4 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.
  • Figures 5 and 6 are two perspectives of the housing part of the external cables, in observation of said piece respectively by the outer part and by the inner part.
  • Figure 7 is a perspective of the part that can be incorporated to cover the access to the terminals of the application circuit breaker.
  • Figure 8 is a perspective of the locking button of the previous piece.
  • Figure 9 e3 a perspective in observation on the inside of an outer covering cover of the housing part of the outer cables.
  • Figure 10 is a perspective of the cover of access cover to the terminals of the differential current detector in the recommended housing.
  • Figure 11 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, as well as the gaps for the connection terminals, a cover (2) that closes the whole assembly being attachable at the top.
  • a piece (5) in the form of an "L” is attached, which is inserted with one of its branches in a housing (6) defined on one side of the socket (1) with opening at the front.
  • the mentioned piece (5) is in the assembly arrangement with the outer branch coming out laterally with respect to the socket (1), while in the insertion of the coupling it is possible with a certain set of movement in and out in the hollow of accommodation (6).
  • Said piece (5) partially has along its outer branch ribs (7), alternatively defined by one and the other face, those of the outer part corresponding at the end with holes (8) through to the inner face; which grooves (7) in turn extend correspondingly along the entire length of the insertion branch, as seen in Figures 5 and 6.
  • the arrangement of the mentioned part (5) in the assembly results in such a way that the outer branch thereof is in a position in front of a lateral zone, where the application circuit breaker of the differential current detector accommodable in the housing is recommended. , so that the electrical connection between both devices is feasible by means of bridging cables that are housed in the grooves (7), whereby said cables are perfectly isolated from each other, and can even be bare cables, since the separation of the grooves (7) 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 (8), such as those that the socket (1) has on the back, so that the connection cables that leave the differential current detector are arranged housed in the grooves (7) of the piece (5), moving it outward to allow the circuit breaker to be placed in front of it and once the circuit breaker is placed in that position, said part (5) is moved inward, whereby The ends of the connecting cables are to be accommodated correspondingly in the circuit breaker terminals, being only necessary to tighten the pressure screws of said terminals to ensure the connection.
  • accessory parts (11) are also incorporated, such as the one shown in Figure 7, which are arranged in the assembly on conformations (12), ensuring installation by anchoring by means of an actionable button (13), as shown in figure 8, which is included by a recess (14) of the respective piece (11), said button (13) having toothed pins (15), by those that by pressure are engatilla in a corresponding conformation (16) of the branch of the piece (5), thus establishing an assurance that prevents disassembly.
  • the pieces (11) have tabs (17) that they protrude from them at the rear, so that said tabs (17) are located in the assembly arrangement correspondingly above the manipulation accesses of the terminals of the coupled circuit breaker, thus establishing a protection seal with respect to said terminals.
  • the application apparatus can be of two, three or four connections, in which case the socket (1), the cover (2) and the part (5) will be dimensionally suitable for each case, so that the part ( 5) does not vary with respect to the insertion branch in the socket (1), but on the contrary the outer branch is half the length in the embodiment for two connections.
