Description

Polarized relay The invention relates to a polarized relay comprising a

  coil body arranged in a case of a case, a permanent magnet as a frame which can move between stops, and a second case edge in which are arranged the contacts to be put in -cuit, which can be actuated by a push rod passing through F; a wall of the second housing chamber and

actuated by the armature.

  necessary to adjust the stops of the frame separately, because the pole plates covering the ends of the cylinder head constitute stops for the movement of the pivoting frame Before placing the case cover, the recesses in the bottom of the case provide the adjustment After fitting the cover, the recesses also ensure the adjustment of the cylinder head and the axle

pivot.

  In a preferred embodiment of the invention, the cylinder head extensions are arranged in the region of the ends of the cylinder head covered by the pole plates and the recesses provided for the extensions and the recesses for the pivot axis located on the bottom of the case and on the cover of the

  case are aligned respectively.

  Other advantageous embodiments of the invention will appear

  in the following description of an exemplary embodiment On the

  drawing, fig 1 is an elevational view of a relay, the housing cover being open, fig 2 is a sectional view along line II It the housing cover being closed; and fig 3 is a partial view along line III III of

fig 1.

  A relay box has a lower part 1 of a box with a bottom 2, and a cover 3 On the four sides of the lower part, snap-on spouts 4 are formed on

  which the cover 3 snaps in through the holes 5.

  In the housing is formed a first chamber 6 for a coil body 7 and a second chamber 8 for contacts 9 and 10 to be connected; in this case, the contact 9 is rigid and the contact 10 is made of elastic material. Between the two chamber chambers 6 and 8 is a third chamber chamber 11 for a pivoting frame 12 The first chamber 6 is separated from the third chamber 11 by a wall 13 which spares the sides of the passages 14 for the yoke calipers 15 and 16 The second housing chamber 8 is separated from the third chamber 11 by a continuous wall 17 which includes a slot 18 to guide a rod

control button 19.

  The coil body 7 is introduced into the chamber 6 with the yoke calipers 15 and 16 plugged in. End plates of the coil body 7 bear on the one hand on the lower part of the housing 1 and on the other hand on the wall 13 The connections 21 of the coil 7 exit outside through the lower part

housing 1.

  The yoke calipers 15 and 16 penetrate through their ends into the third housing chamber 11 At their ends 15 ',

  16 'are formed from the lower 22 and upper 23 extensions.

  To receive the lower extensions 22, recesses 24 and

  are formed in the bottom of the housing 2 To receive the extensions

  upper gements 23, there is provided in the housing cover 3

recesses 26 and 27.

  Between the cylinder head ends 15 'and 16' is placed the arma-

  pivoting structure 12 It consists of a permanent magnet 28

  on which are fixed on each side of the pole plates 29 and 30.

  The pole plates 29 and 30 protrude beyond the permanent magnet

  nent 28 and cover the cylinder head ends 15 'and 16' o The pivoting frame 12 is fitted on a pivot pin 31 pressed on the one hand into a recess 32 in the bottom of the housing 2 and on the other hand into a recess 33 of the housing cover 3 The recesses 24, 32, 25 of the bottom 2 as well as the recesses 26, 33, 27 of the cover 3 are respectively aligned The recesses 32 and 33 are located in the middle between the recesses 24 and 25, and 26

and 27.

  Against one of the free ends of the pole plate 30 supports the control push rod 19 It extends up to a

  free spring arm 10 'from contact 10.

  The lower part of case 1 has a support arm

  overhang 34 on each side of which connectors and 36 are snapped onto contacts 9 and 10 on pins 37 (see fig 3) Contact 9 is made in one piece with connection 35 and it is introduced into the housing chamber 8 through the bottom across

  an opening 38 The contact 10 is for example welded to the connection-

  36 and it is introduced through the cover side into the chamber 8 A separation column 39 is produced in the housing chamber 8 between the contacts 9 and 10 o The connections 35 and 36 correspond to A

  on the one hand, the connecting fingers 40 for connecting the connectors

  cords 35 and 36 to a printed circuit board On the other hand, they are provided with connection tabs 41 for plugs. It is thus possible to pass high currents through the connection tabs; they don't need to go through

  the connecting fingers 40 and the printed circuit board.

  The relay described is a bistable polarized relay. During a positive pulse, it goes to a connection state and during a negative pulse, it goes to the other connection state. The restoring force of the elastic arm 10 ′ and 1 the permanent magnet 28 are dimensioned so that the restoring force of the elastic arm 10 'does not move the permanent magnet 28 In the position of the pivoting armature 12 shown in fig 1, the contact 10 is closed The pole plate 30 presses on the breech end 15 'and the pole plate 29 presses on the breech end 16' In response to an appropriate impulse, the pivoting armature 12 switches from where it results that the pole plate 29 come

  abut against the cylinder head end 15 'and the pole plate 30.

  against the cylinder head end 16 'By means of the control push rod 19, the contact 10 lifts from on the

contact 9.

  The assembly of the parts in the lower part of the housing 1 is simple and ensures without problems the correct alignment of the parts. During the fitting, 11 coil bodies 7 with the yoke calipers 15 and A 16 are first introduced into the chamber. 6 to

  what the extensions 22 penetrate into the recesses 24, 25.

  Then, the pivoting armature 12 is introduced into the chamber 11;

  in so doing, the pivot axis 31 enters the recess 32.

  Then, the contacts 9 and 10 are introduced into the chamber 8 so that the connections 35 and 36 snap onto the nipples 37 Finally, the coanand push rod 19 is inserted into the slot 18 Then, the housing cover is snapped on 3 on the lower part of case 1, from which it follows that the extensions 23 and the pivot axis 31 penetrate into the

  recesses 26, 27 and 33 of the housing cover 3.
