Definitions

  • the present invention relates to an electromechanical contactor comprising a housing which houses a mobile contact support, the housing having a front portion provided of connection terminals accessible by a front face, as well as a pusher mobile that is linked to the contact support and is visible and accessible by the face before.
  • a contactor is described for example in DE-A-2 950 438.
  • Contactors of this type are commonly used to control loads low voltage electric. It is often planned to fix at the front of the case a such contactor an electromechanical additive block having an auxiliary function of signaling or other usable in an automation scheme.
  • the additive block has auxiliary contacts and a movable element arranged to cooperate with the pushbutton of the contactor housing to control the auxiliary contacts.
  • the block additive can be removably attached to the contactor housing, usually using shackles provided on the front of the housing. It turns out that one can visualize the state of the contactor depending on whether the pusher is pulled out or retracted on the front side; on the other hand, the pusher is also used to manually test the correct operation of the carrier of the contactor's movable contacts. But it can be dangerous to perform this test, which in fact switches the load when the contactor is under pressure.
  • the object of the invention is to prohibit the manual actuation of the pusher without altering the ability to view the state of the contactor and benefiting from the arrangements made the front of the contactor housing to ensure the attachment of a frontal additive block or in benefiting from similar provisions.
  • the housing of the contactor offers on its front face and near the pusher mobile coupling elements interlocking or snap adapted to receive an additive block that can be coupled to the pusher or adapted to a fitting in the direction the height of the housing; a cover is removably assembled to the part front housing to hide the mobile pusher, being mounted on the front housing using assembly forms cooperating with the fastening elements.
  • the mounting of the cache uses existing fastening elements for assemble an additive block and / or facilitate an intuitive assembly in the manner of a block additive.
  • the cover may advantageously be a wafer which has a portion transparent in front of the pusher and a recessed portion lined with grooves guide to fit and slide, in the direction of the height of the contactor, on the fastening elements; stop shoulders provided at the ends of the grooves preferably cooperate with abutment parts provided in particular on the fastening elements.
  • the cover preferably has a width substantially identical to that of the housing and a height such that the terminals remain accessible when assembled to the housing, while that it offers on a large side a transversal surface adjacent to the terminals and facilitating the wiring.
  • the contactor shown comprises a housing 10 having a front portion 10a and a rear part 10b.
  • the rear portion 10b is arranged to allow the attachment of the contactor on a support, while the front portion 10a provides a front face 11 provided with openings 12 for access to terminals 13.
  • the terminals have a control or command function, while other terminals 14 of contactor, namely power terminals, are located at the rear of terminals 13. It is of course any other arrangement of the terminals may be provided, the terminals 13 in particular being able to be power terminals.
  • the front face 11 has an opening 15 through which the end protrudes free 16a of a movable pusher 16 secured to or connected to a movable contact holder not represented, which is housed in the housing 10 and which is able to move perpendicularly to the front face 11 in response to the solicitation of an electromagnet.
  • the end 16a of the pusher is output when the contactor is at rest (illustrated state figure 1) and retracted when the contactor is activated.
  • the pusher acts as a drive member for a contact carrier member specific to the additive.
  • the pusher has a test function to allow a operator to check, by pressing the pusher, if the switch operates normally.
  • the grooves 18 and 19a allow the sliding of the additive block 30 or a cache 20 parallel to the front face 11 of the contactor and in the direction of the height switch (as indicated by the arrow in Figure 3).
  • the sliding of the additive block or cache allows the attachment, here by interlocking, on the fixed pins 17 and the 19.
  • the tenons 17 further have a stop function for the additive block or for Cache.
  • the cover 20 is a plate of opaque insulating plastic of general contour rectangular provided with a central transparent portion 21 such as a window located, in the mounted position (FIG. 2), in front of the driving end 16a of the pusher 16 and to see the state of it and thus to note the state on or off of the contactor. It is understood that the cache simultaneously prohibits any test operation to the operator.
  • the cover 20 comprises towards the front face 11 of the contactor a rear face 20a which comes to apply when nesting against the face 11 and remains in contact against this face by draft effects including grooves 23.
  • the cache 20 provides a recessed portion 22 lined with guide grooves 23 to slide on the elements 17,19 with at the end of the grooves abutment shoulders 24 which cooperate with the tenons 17.
  • the grooves 23 have a first portion 23a cooperating with the grooves 19a and a second portion 23b, narrower than the portion 23a, cooperating with the grooves 18 (themselves less spaced than the grooves 19a).
  • the cover can thus be engaged and maintained very easily, in the manner a passive additive.
  • in the lower part of the recessed portion 22 opens a passage 25 for a sealing member 26 which blocks the pusher.
  • the cover 20 provides a flat transverse surface 27 which facilitates the wiring in the access openings 12 to the terminals 13.
  • the additive block 30 has a rear face 31 with a movable plug 32 perpendicularly to the front face 11 of the housing 10 and attachable to the end 16a of the 16.
  • the block 30 can be applied to the front face 11 (see Figure 3).
  • the block additive 30 has guide grooves 33 adapted to cooperate with the grooves 18 of the 17 and with the grooves 19a of the projection 19. Shoulders 34 are provided at edge of the grooves 33 to apply at the end of the nesting race according to the arrow of Figure 3 against the tenons. It goes without saying that if other means are insert or snap the additive block on the contactor housing, the cover can be removably attached to the front portion of the housing 10 using these means.
