Definitions
- the present invention relates to an electrical switch of the push button type. latching, intended for emergency stops and comprising a body and a control button mounted on a cylindrical body and biased by a spring reminder.
- a push-button type switch for hooking allows actuation electrical contacts when an operator presses the push button at when to cause an emergency stop.
- the operating push button is mounted on a body in which a mobile piston and a mobile pusher are housed, this the latter used to actuate electrical contacts.
- This piston and this pusher are capable of sliding and pivoting in the body, along an axis, while being relatively fixed relative to each other.
- the piston is retained in position ⁇ on ⁇ by a lock.
- the piston moves, under the effect of an arming spring, to a tripping or stopping position, position in which it is maintained by this same lock, after actuating the electrical contacts.
- the object of the invention is to provide a snap-on push-button, the security is improved.
- the switch according to the invention is essentially characterized by the fact that the piston is provided with a susceptible control member, when the button is pushed, to actuate the first so-called stop lock immobilizing the pusher in position ⁇ rest ⁇ and then release the pusher which can come in the hanging position where it is immobilized by the second lock used for hanging.
- control pusher has means guide which are guided on helical ramps formed in the body.
- the body has a ramp used for recoil of the bolt when the pusher pivots about its axis of rotation and a boss allowing indexing of the pusher and the piston in position hanging.
- the push button head which is illustrated in FIGS. 1 to 5 is associated with electrical contact blocks which are not shown. It includes, at front, a manual control push button 1 on which the operator can press when triggering the emergency stop. This push button 1 mounts sliding on a body 2 in which are housed the different components and which is used for fixing to a not shown fixing panel.
- the body 2 which has a tubular and cylindrical shape around an axis XX ′, is consists of a front part 21 and a rear part 22, the latter being moreover small diameter and separated from the front part by a shoulder.
- This body 2 is committed by its rear part 22 in an opening of a fixing panel to which it can be tightly fixed by an external seal, by an anti-rotation plate 91 and by a fixing nut 92.
- the manual control push-button 1 has a cylindrical shape in mushroom, the upper part 11 serving as a pusher and the lower part 12, shaped skirt, covering the body 2.
- Immobilization means provided on the body 2 and on button 1 oppose their relative rotation. These means can be formed by internal grooves of the skirt which slide on grooves external of the body or by a sliding keying.
- Button 1 is also stopped in the high position, relative to the body 2, by tenons 61A, 61B which come in abutment, upwards, against helical ramps 28A, 28B formed in the body 2.
- a coil spring 3 is mounted so as to be compressed between the body 2 and button 1 and to communicate to it a restoring force.
- One of his ends is housed in an annular housing of the body 2 while the other end is housed in an annular housing of button 1.
- the push button 1 receives, in an axial housing, a lock barrel 93 which can turn and be actuated by a key not shown. Barrel 93 can turn in its housing when the key is present.
- the barrel 93 is linked in rotation and in translation to a piston 4 which is housed and guided so as to slide and pivot along the axis XX 'in a bore 24 of the body 2.
- a seal is mounted around the piston 4 so as to ensure sealing with the body.
- the piston 4 cooperates with an internal control pusher 6 used to activate the electrical contacts.
- This pusher 6 is also housed and guided in translation along the axis XX 'in a bore 23 of the body 2 while remaining free to pivot around this axis.
- the piston 4 and the internal pusher 6 can slide one by relative to each other but they have means 42 linking them in rotation around the axis XX '.
- These means can be constituted by a keying or by grooves and grooves which are conjugated and formed respectively on the piston and on the pusher.
- a coil arming spring 5 is mounted so as to be compressed between the piston 4 and the internal control pusher 6. Its ends are housed on one side in a housing of the piston 4 and on the other side in a housing of the interior pusher 6.
- the interior pusher 6 carries a first sliding lock 7 serving as a stop in on position and a second lock 8 used for latching in the stop position, after triggering.
- the latch 8 can slide along an axis perpendicular to X-X 'and it is subjected to a return spring tending to push it back out of the pusher.
- the stop latch 7 can slide along an axis perpendicular to XX ' and is also subjected to a return spring tending to push it out of the pusher.
- the stop latch 7 In the rest position, the stop latch 7 can abut against the shoulder 25 so as to immobilize the pusher 6 (at the end of the front stroke).
- This latch 7 is provided with a support ramp 71 which can cooperate with a finger unlocking 41 of the piston 4. When this unlocking finger 41 comes to rest on ramp 71, he pushes the lock 7 into its housing, counteracting the action of the associated spring, which releases the pusher 6 from the on position.
- the internal pusher 6 has, projecting, reset pins 61A and 61B which are guided upwards against helical rearming ramps 28A and 28B formed in the body 2.
- the rearming takes place after triggering and stop, by rotation of the 4-pusher piston assembly 6 which has the effect of making reassemble the pusher 6 to the ⁇ rest ⁇ position (front limit switch).
- the pusher 6 sinks into the bore of the body 2 along the axis XX 'in response to a pressure exerted on its front part of the push button 1, at against the effort of a return spring 3. During this emergency stop phase, it is immobilized in rotation around X-X 'and moves from the rest position (end limit switch) in the latching and release position (limit switch back).
- the body 2 has, in its bore 27, a ramp 27A serving to depress the latching lock 8 when the operator pivots the pusher 6 around of the axis XX '.
- This unlocking of the lock 8 has the effect of releasing the pusher 6 from its hooking and stopping position and allows it to go back to the running position.
- a boss 27B is formed before the recoil ramp 27A so as to allow the plunger 6 and the piston 4 to be indexed in the stop position and hanging.
- the push button head which has just been described above operates from the next way.
