Definitions

  • the present invention relates to a motion or proximity detection switch apparatus, comprising a sensitive member for performing this detection, and a body defining a housing for a switch assembly controlled by the sensitive member and connected to the outside by a electrical connection cable, the housing being closed by a removable cover.
  • Position or safety switches for industrial use are well known (eg XCK-J products, see Telemecanique catalog "position switches", April 1999).
  • the wiring of the contact block of such devices is difficult and different devices in a range require different housings when it is desired to connect to these boxes of different diameter cables or add to these housings cable entries with different threads.
  • the document WO-99 / 27,551 shows a position switch in which the body and the cover each have a threaded half-flange for receiving a tightening nut of a sealing sleeve.
  • the tightening of the nut has the effect of deforming or repositioning the lid, which alters the sealing qualities of the device.
  • the invention aims to facilitate the assembly and wiring, in the body of such devices, a switch block with connection elements, respecting a good seal of the assembly, while allowing to use cables of different diameters or fittings of different characteristics without changing the body.
  • the removable cable gland is introduced by means of interlocking elements, by a sliding movement in a direction substantially perpendicular to the main wall of the cover, in guiding and holding forms provided in the body. It is thus possible to add to the same device body fittings differentiated by their internal diameter or by their type of thread.
  • the guiding and holding forms of the body are preferably rectilinear and the interlocking elements of the connector form a frame provided on its sides with complementary insertion shapes of the guiding and holding forms, the switch block and the coupling being introduced. in the body of the device in the same direction.
  • the frame is advantageously symmetrical, located at the end of the connector and housed partly in the housing of the switch unit and partly in guiding and holding forms provided in the cover.
  • the fitting carries an outer seal and the lid is mounted on the body by means of pivoting members, preferably hooks, provided near one end and having at the other end a screw for fixing to the body, the pivoting elements being offset relative to the plane of the main wall of the lid so as to increase the tightening torque of the joint.
  • the switch apparatus shown in the figures is a position switch, which includes a body 10 and, as a member responsive to the movement of an object, a pivoting lever assembly 11 attached to the body near a first end 10a. of it.
  • the body is of parallelepipedal general shape and defines near this end 10a a housing 11a to receive a portion of the assembly 11; the body also defines in its intermediate portion 10c a housing 12a for receiving, by introduction in a direction Y, a removable switch unit 12 which is actuated by the assembly 11, the housing 12a being normally closed by a cover 20.
  • the switch block 12 has mechanical switching elements or electronics and is connected to a device or circuit external to the device by means of connection elements 12b to which conductors connected in a cable C are connected (see figure 2 ) which is held by a connector 30 itself attached to the body 10 to a second end 10b thereof.
  • Block 12 shows up ( Figures 1 and 2 ) a snap-on plate 12c which hides the connection pads after wiring.
  • the body 10, the cover 20 and the connector 30 are made of insulating or metallic material.
  • the body 10 of the apparatus has substantially flat side walls 13 and a flat bottom wall 14 of plane P delimiting the housing 12a.
  • the body 10 has a passage wall 15 for the cable C.
  • the wall 15 has a semicircular recess which forms a half-flange 16 to form a passage for the cable C.
  • To the interior of the the body relative to the collar are provided rectilinear forms of guiding and holding 17 of the connector, for example grooves and / or ribs directed perpendicular to the plane P of the bottom wall 14 (vertical in the figures).
  • a cover 20 is fixed to the body to close the opening through which the switch block 12 is introduced. It comprises a main closing wall 21 which is flat or left, extending substantially parallel to the plane P of the rear face 14. to cover the housing 12a.
  • the lid 20 has transverse walls 22 which tapers from its foot end 22b which is close to 10b towards its head end 22a which is close to 10a.
  • the walls 22 have for example a generally trapezoidal or triangular shape and each end with a hook 23 intended to bear on the body cooperating with a socket 18 formed in a side wall 13 of the body at a substantial distance from the wall 21, for example midway between the walls 21 and 14. Instead of hooks 23, it can realize snap pins.
  • the sockets 18 are located closer to the wall 15 than the shapes 17 and below the X axis ( figure 2 ).
  • the cover 20 In the middle of its head end 22a, the cover 20 has a hole for a screw 24, this screw cooperating with a threaded hole in the body to secure the cover.
  • the cover 20 has a wall provided with a semi-circular recess which forms a half-flange 26 completing the half-flange 16 of the body 10.
  • Straight shapes 27 for guiding and holding the connection 30 (vertical in the figures), for example symmetrical shapes 17 relative to the assembly plane, are provided inside the cover.
  • the cover 20 carries around its periphery a bi-injected sealing bead 28 intended to cooperate with the upper edge of the body which borders the housing 12.
  • the connector 30 has a generally rotational body 31 having a threaded portion 32 of X axis for receiving the cable C and a not shown liner providing local sealing around the cable.
  • the lining is pressurized by an unspecified member which is screwed into the threaded portion of the passage 32.
  • the connector has a cylindrical portion adapted to the half-collars 16,26, with an outer groove 33 in which is housed an O-ring seal 34, which seal therefore cooperates with the half-collars; in its part intended to be housed inside the body 10, the fitting 30 has a substantially square or rectangular mounting frame 36.
  • the cheek 36 forms a symmetrical frame provided on its sides with complementary rectilinear insertion shapes 37 (for example ribs and / or grooves) of the shapes 17 of the body so as to allow the coupling to be removably mounted.
  • the shapes 37 cooperate with the shapes 17,27 by interlocking; the shapes in question may have a detent effect or hard point associated with the interlocking effect.
  • the connectors 30 may thus differ by their part enclosing the cable and / or their gland thread while maintaining a part integrated into the body, including a mounting flange 36, which remains unchanged.
  • the symmetrical H-shape of the frame allows it to be mounted in the body in two 180 ° staggered positions and to obtain a similar fit in the body and in the lid.
  • the wiring of the switch unit 12 is carried out conveniently while the block has been introduced in the direction Y perpendicular to the bottom wall 14 inside its housing 12a of the body 10.
  • the fitting 30 of the type suitable for the cable, and engaged on the cable, is then slid into the shapes 17 in the same direction Y, with contact of the seal on the half-flange 16.
  • the cover 20 is engaged by its hooks 23 on the sockets 18 and by its forms 27 on the shapes 37 of the connector, then is pivoted around these sockets, while the O-ring 34 bears on the half-flange 26.
  • the tightening of the single fastening screw 24 makes it possible to press the seal 34, and this with increased effort by the shift of the hooks 18 relative to the plane P of the wall 21 of the lid.
  • the invention described with regard to a position or safety switch, also applies to all proximity sensors comprising connection blocks or removable switch blocks.
