Definitions
- the invention relates to an electrical switch according to the preamble of patent claim 1, 2 or 3 and a method for adjusting the switching point of such an electrical switch according to the preamble of patent claim 12 or 13.
- a snap switch with a contact system consisting of fixed contacts and movable contact tongues is known.
- One end of the snap springs is operatively connected to the contact tongues.
- the other end of the snap springs is mounted on a body, which in turn is arranged in a movable actuator.
- the actuating element acts on the snap springs for switching the contact system when it moves.
- the body is longitudinally displaceable in the actuator by means of a screw, so that the bearing for the snap springs is adjustable in the direction of movement of the actuator.
- the invention has for its object to design an electrical switch such that the switching point of the contact system can be easily adjusted subsequently.
- the adjustment process should also be suitable for largely automated mass production of the switch.
- the bearing for the contact tongue of the contact system and / or the contact tongue itself and / or the fixed contact of the contact system and / or part of the actuating member is adjustable in the direction of movement of the actuating member.
- This setting of the bearing and / or the fixed contact and / or the contact tongue and / or a part of the actuating member is preferably carried out by a mechanical or thermal deformation, in particular a permanent deformation, which occurs during or after the assembly of the contact system on the bearing or the fixed contact receiving carrier or the contact tongue or a part of the actuator is introduced.
- This deformation can be a plastic deformation.
- connection designed as a carrier between an electrical connection of the switch and the bearing can have a first section which extends approximately transversely to the direction of movement of the actuating member. This can be followed by a second section running approximately in the direction of movement of the actuating member.
- the first and second sections then form a bulge on the support for the bearing, which bulge is formed substantially perpendicular to the direction of movement of the actuating member. This bulge has an approximately U-shaped, semi-S-shaped, question mark-shaped or S-shaped shape.
- the bearing can be adjusted to adjust the switchover point by means of a tool which acts on the support for the bearing and in the direction of the bearing. It makes sense to design the tool in a wedge shape. To adjust the bearing, this tool is then displaced approximately transversely to the direction of movement of the actuating member, as a result of which the tool acts on the first section of the carrier extending transversely to the direction of movement of the actuating member, which results in an expansion of the bulge on the carrier. If necessary, a further tool with a support surface can be used, the support surface being in contact with the second section running in the direction of movement of the actuating member during adjustment.
- the tool can also be an embossing tool.
- At least one embossing can be introduced into the carrier for the bearing by means of the embossing tool. This deformation introduced into the carrier by the embossing causes the bearing to move in the direction of movement of the actuating member.
- the carrier receiving the bearing, the contact carrier receiving the fixed contact, the switching lever or another functionally relevant component of the switch is at least partially made of a thermally deformable material.
- a thermal action of this type takes place for adjustment, so that the carrier, the contact carrier, the shift lever or the other component undergoes a deformation, the deformation having a component in the direction of movement of the actuating member. It is further preferred to carry out the thermal action by means of individual pulses of laser beams, as a result of which the size of the deformation can be controlled in a targeted manner. If the action on the inside of the housing for the bearing or the contact carrier for the fixed contact or the contact tongue is to take place, it is expedient to provide a window for the laser beams on the housing of the switch.
- the contact system is dimensioned taking into account the maximum tolerances that occur so that after assembly the contact system does not yet reach the switching point in the assigned actuation path of the actuating member.
- the actuating member is then adjusted by the associated actuating path and the adjusting tool then acts on the carrier for the bearing, the contact carrier, the contact tongue or the shift lever by advancing the wedge-shaped tool in the direction transverse to the direction of movement of the actuating member , the embossing tool introduces corresponding embossments or thermal heating by laser beams or the like takes place. Due to these effects, a deformation takes place, the causes an adjustment in the direction of movement of the actuator.
- the action then continues until the contact tongue snaps.
- the snap can be easily determined by opening, closing or switching the contact system when the switch with its electrical connections is connected to an electrical circuit during adjustment.
- the adjustment process can be ended by means of the adjustment tool when the bearing, the fixed contact, the switching lever or another functionally relevant component of the switch has reached a predetermined position. The attainment of this position can be determined by optical monitoring, for example by means of a light barrier.
- the advantages achieved by the invention are, in particular, that the adjustment of the switching point and the differential path for the switch as well as the contact length or the contact distance for the contact system is made possible by a simple, error-prone and inexpensive arrangement.
- the adjustment is carried out in a simple manner, avoids adjustment problems and can be automated.
- Such a switch is therefore particularly suitable for mass production.
- the invention can be used particularly advantageously in small switches, such as snap-action switches or microswitches, and in SMD switches. These can be produced with much tighter tolerances with regard to the switching point of the contact system or the differential path for the actuating member than before, without the dimensional tolerances for the individual parts of the contact system being excessively restricted. Rather, the influence of the tolerances is the Individual parts largely eliminated. This, in turn, allows the switch's overtravel to be increased, which is desirable for the switch in many applications. Even switches that do not meet the specifications can still be adjusted subsequently, so that the rejects in the manufacture of the switch are reduced.

- FIG. 7 shows a section as in FIG. 3 according to a further embodiment
- Fig. 9 shows an electrical switch as in Fig. 1 according to another embodiment and Fig. 10 shows a section as in Fig. 3 in yet another embodiment.
- an electrical switch 1 in the form of a microswitch with a housing 2 can be seen.
- an actuating element 5 designed as a tappet protrudes which can be moved essentially in a direction 20, 20 ′ running perpendicular to the upper side 3.
- a switching lever 7 acts on the actuating member 5 to move it, so that the actual actuation of the switch 1 takes place via the switching lever 7.
- the actuator 5 is provided with an elastic sealing hood 6 to protect the interior of the housing 2.
- a contact system 9 is arranged in the interior of the housing 2 and can be designed as an opener, closer or switch.
- the contact system 9 consists of at least one fixed contact 10, a movable contact tongue 12 as a switching contact and a spring 13 which is in operative connection with the contact tongue 12.
- the contact system 9 has yet another fixed contact 11, so that the contact system 9 acts as a changeover switch.
- the fixed contacts 10, 11 are arranged on carrier parts 14, 15. With its longitudinal direction, the contact tongue 12 is arranged to be movable approximately transversely to the direction of movement 20, 20 'on a bearing 18 which is designed in the manner of a cutting edge bearing.
- the bearing 18 is located on a part designed in the manner of a carrier, which thus represents a carrier part 16. In the region of the bearing 18, the support part 16 runs roughly parallel to the direction of movement 20, 20 '.
- the spring 13 designed as a tension spring is suspended at one end in the contact tongue 12 and at the other end in a further carrier part 17.
- the carrier parts 14, 15, 16, 17 are attached to the base 24 of the housing 2.
- connection 8a, 8b, 8c, 8d protrude, how to 4 in particular.
- the connections 8a, 8b, 8c, 8d are designed in the manner of contact surfaces.
- the contact surfaces in turn run essentially parallel to the underside 4 of the housing 2 and are flat or even on the base 24 of the housing 2.
- the switch 1 can be mounted on a printed circuit board using SMD technology (SMD - Surface Mounted Device) and can therefore be used by means of a Pick and place machine can be processed further.
- the contact system 9 is in electrical connection with the connections 8a, 8b, 8c, 8d via the carrier parts 14, 15, 16, 17.
- the connections 8a, 8b are assigned the carrier parts 14, 15 for the fixed contacts 11, 10, the connection 8c the carrier part 16 for the bearing 18 and the connection 8d the carrier part 17.
- the contact tongue 12 bears against the fixed contact 11.
- an electrical connection is thus established between the connections 8a and 8c.
- the actuating member 5 is moved in the direction 20, the actuating member 5 acting on the spring 13.
- the switching point of the contact system 9, at which the contact tongue 12 snaps, is reached when the line of action 19 of the spring 13 approximately coincides with the longitudinal direction of the contact tongue 12.
- the switching point is thus assigned a specific actuation path in the direction 20, which the actuating element 5 covers by moving from the rest position until the switching point is reached.
- the contact tongue 12 rests on the fixed contact 10, an electrical connection being made between the connections 8b and 8c in this second switching position of the contact system 9.
- the actuating member 5 is moved back into the rest position, the actuating member 5 likewise being assigned an actuating path in the direction 20 ′ until the switching point is reached.
- the difference path is the difference between the size of the actuation path in the direction 20 and one towards 20 '.
- the desired size for the actuation path and thus the tolerances for the switching point and the differential path are generally determined by the use of switch 1.
- the switch point which in turn is assigned to the actuation path, is designed to be adjustable by adjusting part of the contact system 9 in the direction of movement 20, 20 'of the actuating member 5.
- the bearing 18 according to the invention is designed to be adjustable in the direction of movement 20, 20 'of the actuating member 5.
- the carrier part 16 for the bearing 18 has a first section 21 which extends approximately transversely to the direction of movement 20, 20 'of the actuating member 5. It is particularly advisable to arrange the first section 21 approximately perpendicular to the direction of movement 20, 20 '.
- the first section 21 is followed by a second section 22, which extends approximately in the direction of movement 20, 20 'of the actuating member 5.
- the second section 22 is followed by a third section 23. which runs approximately parallel to the first section 21 and is fastened in the base 24 of the housing 2.
- the third section 23 contacts the terminal 8c.
- the first and second sections 21, 22 form a type of bulge on the carrier part 16 for the bearing 18, which bulge is formed approximately perpendicular to the direction of movement 20, 20 'of the actuating member 5.
- This bulge could also be approximately half-S -shaped, question mark-shaped or also U-shaped, the "U" being arranged horizontally.
- the bearing 18 is adjusted during the assembly of the contact system 9 or subsequently on its assembly before the housing 2 is closed.
- an opening (not shown further) can also be provided in the housing 2 in order to permit subsequent adjustment.
- a tool 25 acts on part of the bearing 18 in such a way that a component of the direction of action of the tool 25 in the direction of movement 20, 20 ′ of the actuating member 5 and thus towards the bearing 18 is aligned.
- the deformation expediently consists of a plastic deformation of the carrier part 16.
- the tool 25 can be approximately wedge-shaped on the side facing the bearing 18. With this wedge-shaped side, the tool 25 then acts on the first section 21 of the carrier part 16 which runs approximately transversely to the direction of movement 20, 20 'of the actuating member 5. For this purpose, the tool 25 can be displaced approximately transversely to the direction of movement 20, 20 'of the actuating member 5, that is to say in the direction of the arrow 26, during the setting process. During this displacement, the wedge-shaped side of the tool 25 comes into contact with the section 21 and presses it further and further upwards with continued feed in the direction 26, so that a processing is carried out the bulge takes place and the bearing 18 is adjusted in the direction of movement 20 'of the actuator 5.
- a support on the second section 22 can be carried out by a tool 29 with a support surface 30 during the setting process, which is shown in FIG. 5 is indicated with dashed lines. If necessary, a tool can of course also act on the first section 21 in such a way that the bulge is compressed, as a result of which the bearing 18 is adjusted in the direction of movement 20 of the actuating member 5.
- the snapping of the contact system 9 is used to end the adjustment process.
- the contact system 9 is dimensioned, taking into account the tolerances that occur during the manufacture of the individual parts, such that the switching point of the contact system 9 is not yet reached after assembly during the defined actuation path for the actuating member 5.
- the actuating member 5 is adjusted by the defined actuating path and the bearing 18 is adjusted as described above until the contact tongue 12 snaps.
- the snap-in of the contact tongue 12 can be determined optically by means of a light barrier or the like or, preferably, by the electrical opening, closing or switching over of the contact system 9, depending on its design. For this purpose, only the switch 1 with its connections 8a, 8b, 8c and possibly 8d to one to connect electrical circuit. When the contact tongue 12 snaps, the switching signal of the switch 1 then changes, which in turn can be used as a trigger for stopping the tool 25.
- the switch 1 for adjustment is introduced into an adjustment device 40, which is only indicated schematically in FIG. 6, and the electrical connections 8a, 8b, 8c of the switch 1 are connected to a display device 36.
- the display device 36 contains a voltage source 37 which is connected to the terminal 8c.
- Illuminants are also present in the display device 36, for example a green light-emitting diode 38 contacting the connection 8b and a red light-emitting diode 39 contacting the connection 8a. Since the switch 1 is in the first switch position in which the contact tongue 12 is in contact with the fixed contact 11, it lights up the red LED 39.
- a stamp 41 of the adjusting device 40 acts on the actuating member 5 in such a way that the actuating member 5 covers the defined actuating path in the direction of the arrow 20 and is held in this position. Due to the dimensioning of the contact system 9, however, the switching point has not yet been reached, with the result that the contact system 9 remains in the first switching position and the red light-emitting diode 39 continues to light up.
- the adjusting tool 25 of the adjusting device 40 then acts on a part of the bearing 18, namely, as already described, by advancing the wedge-shaped tool 25 in the direction 26, the bearing 18 being adjusted in the direction of the arrow 20 '.
- This advance of the tool 25 is now continued until the contact tongue 12 in the snaps second switching position, whereby the contact tongue 12 comes to rest on the fixed contact 10.
- the red light-emitting diode 39 goes out and the green light-emitting diode 38 lights up.
- the switching point of the contact system 9 is correlated with the defined actuation path of the actuating member 5 and the adjustment process is ended. If necessary, the advancement of the wedge-shaped tool 25 is to be continued somewhat beyond this switching point in order to take account of the springback of the first section 21 on the carrier part 16.
- a switch 1 'in a second embodiment, which can be seen in more detail in FIG. 7, has a somewhat modified contact system 9', parts comparable to switch 1 being provided with the same reference numerals.
- the actuating member 5 which is movable in the direction of movement 20, 20', acts on a first lever arm of a two-armed inner lever 28.
- a spring 13 On the second lever arm of the inner lever 28, one end of a spring 13 is hooked, which in turn is hooked with its other end to a contact tongue 12.
- the contact tongue 12 is movably mounted in a bearing 18, which is shown in FIG. 7 in a partial section by the spring 13.
- the bearing 18 is located on a support part 16 'which makes an electrical connection to a connection 27a.
- the two fixed contacts 10, 11 are arranged on contact carriers 34, 35, which in turn cause a connection to the electrical connections 27c, 27b of the switch 1 'which are designed as plug connections. So that the movable actuator 5 is operatively connected to the contact tongue 12 via the inner lever 28 and the spring 13 for switching the contact system 9 '.
- the contact carrier 34, 35 is plastically stretched by the embossing 32, 33 and the fixed contact 10, 11 is thereby displaced in the direction of movement 20, 20 'of the actuating member 5. If the shift that can be achieved by means of an embossing 32, 33 is not sufficient, it is of course also possible to introduce several embossings 32, 33 or to vary the depth of penetration of the embossing 32, 33. 7 and 8, however, only an embossing 32, 33 is shown in the contact carrier 34, 35. The action of the adjusting tool and thus the stamping in the contact carrier 34,
- the contact distance of the fixed contacts 10, 11 has the desired size.
- the attainment of this position can be determined by optical monitoring of the position assumed by the fixed contact 10, 11.
- a light barrier can be used which, when the predetermined position is reached, emits a signal which in turn is used to end the embossing.
- the bearing 18 for the contact tongue 12, the carrier part 14, 15 or the contact carrier 34, 35 for the fixed contact 10, 11, the switching lever 7 or other components relevant to the function of the contact system 9 can be set mechanically. Also particularly preferred is an essentially contactless adjustment process, which is to be explained in more detail using the following exemplary embodiment.
- the actuation path for the switch 1 is set by a thermal deformation on the shift lever 7.
- the shift lever 7 consists at least partially of a material that is permanently thermally deformable.
- the material may be Trade copper alloys, steel or the like.
- Pulses of laser beams 31 act on one side of the shift lever 7 by means of a laser.
- the point on the shift lever 7 at which the laser beams 31 strike is heated on one side and the material of the shift lever 7 expands at this point. Due to the one-sided heating, the switching lever 7 with one component warps in the direction 20, 20 ", so that the switching lever finally assumes the position designated by reference numeral 7 '.
- the heating can also be carried out in some other way, for example by induction or the like.
- a window 42 that is transparent to the laser beams 31 is attached to the housing 2.
- the laser beams 31 reach the interior of the housing 2 with almost no loss.
- the laser beams are directed onto the contact tongue 12, so that a deformation 43 shown in broken lines is generated on the contact tongue 12.
- the size of the deformation 43 can in turn be used to set the switching point at which the contact tongue 12 switches, and thus the switching point of the contact system 9.
- the switch 1 can be completely assembled and the setting can then be carried out, since a contactless setting can also take place inside the housing 2 via the window 42.
- mirroring and other aids can also be arranged on or in the housing 2 to align the laser beams 31 with the component of the switch 1 to be set.
- the invention is not restricted to the exemplary embodiments described and illustrated. Rather, it also includes all professional training within the framework of the
