Description

Technical Field

[0001] A switch for an electrical device, in particular for an electric tool, the switch having a regulator for setting the rotational speed of the electrical device, wherein a circuit board is arranged in a contact space of a switch housing, wherein the regulator works together with electrical components of the circuit board, preferably with regulating contacts resting on conductor tracks of the circuit board in the contact space, and wherein the regulator can be actuated by means of a slide. Background Art

[0002] Such a switch is known from DE102015113949A1. Such a switch is used, for example, as a multi-way switch in electrical equipment, in particular in drills, electric screwdrivers and other electrical hand tools, or in household appliances. For this, the regulator is adjusted via an operating element that can overcome the reset force and move linearly. A known slide regulator is directly arranged in the power circuit of the electrical equipment or in a control circuit that works at low voltage and low current. The slide regulator that works in the low voltage and low current range provides an output signal that is proportional to the position of the slide regulator, which is delivered to the power electronics. The power electronics enhances the output signal, and the output signal is delivered to the drive unit of the electrical equipment. Thus, the speed of the electric tool can be adjusted, for example, via the slide regulator. In addition to the known slide regulator, the multi-way switch known in the prior art has another switch element for switching the rotation direction of the drive unit or for connecting / disconnecting the electrical equipment. For this, the switch element is usually engaged in the power circuit of the electrical equipment. Alternatively, it can be arranged that the switch element is arranged in the control circuit and its switch signal is transmitted to the power electronics accordingly. The known slide regulator is in the form of a potentiometer, ie, is designed as a variable ohmic resistor with a sliding contact. The sliding contact is connected to an operating element by means of a mechanical transmission.

[0003] It is also known that the slide regulator can be implemented as a capacitive travel sensor, as described in document DE102011002009A1. The document discloses a capacitive travel sensor having a housing that can be mounted on a circuit board. The housing has a receptacle in which a slider is movably supported. The slider is permanently arranged between a first measuring electrode and an opposite ground electrode in a reference region. The sliding movement causes the slider to be introduced more or less into the measuring region between the second measuring electrode and the second ground electrode, wherein the ground electrodes of the reference and measuring regions can be implemented as one-piece electrodes. When the slider moves, the change in the capacitance between the electrodes arranged in the measuring region relative to the capacitance between the electrodes arranged in the reference region is evaluated. For this purpose, the measuring electrode can be arranged on the circuit board, and the ground electrode is integrated in the cover of the housing.

[0004] The capacitive travel sensor and the ohmic travel sensor both operate at low current and voltage in the control loop. In this case, even slight contamination of the contacts and electrodes leads to interference with the controlled electrical device and thus to functional failures of the controlled electrical device. Advantageously, the other required switching elements are also integrated into the control loop. For this purpose, the switch is implemented according to a known arrangement via two exposed contact surfaces arranged on a circuit board, which can be bridged by conductive bridges. However, the disadvantage of this cost-effective construction method is that dust or contaminants entering the area of ​​the contact surface can severely change the transition resistance between the contact surface and the bridge, so that the function of the switch is impaired. In particular, when low voltages and currents are used in the control loop, interference occurs in the case of relatively small contamination.

[0005] When the sliding adjuster is operated, the operating element is pressed into the switch housing against the reset force, and when unloading, it is pressed from the switch housing to the stop. The space in the switch housing is squeezed by the operating element pulled in and out and released again. This forms a pump effect, in which the air pressure in the switch housing changes. The air is thus squeezed out of the housing and then sucked in again. The sucked air also brings pollutants and dust into the switch housing through the smallest openings and cracks. The amount of dust or pollutants introduced into the switch housing is many times greater than the amount when the operating element is not operated and the sucked air is not invaded into the switch housing. Pollutants and dust are particularly deposited on the exposed contacts of the control circuit and cause malfunctions. Summary of the invention

[0006] The object of the invention is to provide a switch, in particular a multi-way switch, which operates in the low voltage range and at low currents, provides a control signal which is proportional to the displacement and which is not susceptible to failures caused by contamination in a simple and small construction.

[0007] This object is achieved in that the adjuster is rotatably mounted and the displacement movement of the slide is converted into a rotational movement of the adjuster by means of a transmission mechanism and the slide is held and guided outside the contact space.

[0008] By holding the slide outside the contact space and guiding it outside the contact space, a change in the air volume in the contact space due to the adjustment movement of the slide is prevented. The rotatable arrangement of the adjuster in the contact space also does not lead to a change in volume. This prevents a pump effect by which dust is sucked into the contact space. In this way, a highly dust-proof switch can be realized, which is characterized by a high degree of operational reliability in a minimal installation space.

[0009] According to a preferred variant design of the present invention, the housing part of the switch housing can rotatably accommodate the converter in the bearing receptacle, and the converter has a driver, by means of which the converter can be connected to the adjuster indirectly or directly in a rotationally fixed manner. In this way, the linear movement of the slide can be converted into the rotational movement of the converter in a minimal structural space.

[0010] It is also conceivable that the converter has one or more fixing elements in the region of the contact space, via which the adjuster is coupled, and the fixing elements preferably have latching projections, by means of which the adjuster is locked in the latching receptacle. This measure can also make automated production simple.

[0011] The mechanical coupling in the transmission between the slide and the converter can be realized simply in that the converter has one or more actuating elements on its side facing away from the contact space, and the actuating elements cooperate with the actuating element receptacle to convert the linear movement of the slide into a rotary movement of the converter. The actuating elements or actuating element receptacles can also be formed in particular by a gear transmission, wherein a gear or a gear part meshes with a toothed rod.

[0012] In order to reduce the consumption of parts and the installation effort, according to a variant of the invention, the converter can have a stop which, in the extended rest position of the slide, abuts against a counter surface of the slide, thereby limiting the adjustment movement of the slide.

[0013] The rotatable mounting of the converter can be realized in a simple manner in that the converter has a base part with a circumferential side wall, by means of which the converter is rotatably inserted into a bearing receptacle of the housing part.

[0014] When the housing component has a sliding surface for the slider outside the contact space and one or more guide parts are connected to the sliding surface indirectly or directly, wherein the slider is guided linearly in the guide part via a guide element, the slider can be guided precisely in the housing component and tolerances between the slider and the converter caused by manufacturing can be minimized, which contributes to reliable function.

[0015] When, according to a variant of the invention, the housing part has a bottom wall, which is arranged spaced apart from a wall element of the housing part and a sliding guide for the slide is formed between the bottom wall and the wall element, the slide is firmly held and guided and is in particular also insensitive to lateral loads acting transversely to the adjustment direction.

[0016] The slide is mounted and fixed to the housing part in a simple manner, i.e. the housing part has a recess in the area of ​​the bottom wall, through which the converter can be inserted into a bearing receptacle in the wall element, and in the installed position of the converter at least one actuating element engages in the fixing element receptacle.

[0017] A further structural simplification is that the housing part has a molded-on spring support in which a return spring is accommodated, which preloads a switching element connected to the slide.

[0018] The switch according to the invention can be characterized in that the regulator has a contact support having at least one receptacle for fastening the regulating contact, thereby achieving a reliable and simple to install correspondence between the regulating contact and the regulator, the regulating contact can especially be configured as a sliding contact.

[0019] A preferred development of the invention provides that the adjuster has a sliding surface in the region of the rear side facing away from the printed circuit board, the sliding surface resting against a wall surface of the housing part to form a sliding guide.

[0020] A rotationally fixed correspondence of the regulator and the converter is achieved in a simple manner if the regulator has a driver receptacle with an asymmetrical cross section and the converter engages in the driver receptacle with a driver having a likewise asymmetrical cross section.

[0021] The multi-way switch can be designed to hold a rotatable positioning element in the contact space, the positioning element having a receiving portion in the area of ​​one of the front sides, so that the contact elements of the left and right switches are held in the receiving portion, and the contact elements are preferably in contact with the matching contacts of the circuit board. The rotatable positioning element also does not cause a volume change in the contact space, thereby ensuring a high degree of sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figures 1 to 3 As shown, the switch has a housing part 200. The housing part 200 is designed as a plastic casting. The housing part has a bottom wall 201, from which opposite side walls 210, a front wall 211 and a rear wall opposite the front wall 211 rise. A notch 202 is introduced into the bottom wall 201. The notch 202 has recesses 203, 204, which are matched to the contour of the converter 100, which will be explained in detail later. The housing part 201 has a wall element 205 spaced parallel to the bottom wall 201. The wall element 205 has two bearing receptacles 206, 207, which are processed into the wall element 205 in the form of notches. As in particular Figure 1 and Figure 2 As shown, a sliding guide with a sliding surface 208 is formed between the bottom wall 201 and the wall element 205. A guide 209 is connected to the sliding surface 208 on the opposite side. The guide 209 is designed as a recessed portion and is processed into the wall element 205. In the area of ​​the front wall 211, a spring support 214 is molded on the housing part 200. The spring support 214 has a spring support for accommodating the spring. Figure 1 The hollow cylindrical inner contour of the return spring 50 is shown in FIG.

[0036] like Figure 2It can be seen that there are molded snap-in elements 215 on the side walls 210 of the housing part 200. Two snap-in elements 215 spaced apart from each other are used for each side wall 210. Figure 3 As shown, a circuit board bracket 216 is molded on the housing component 200. The circuit board bracket is used to accommodate Figure 1 The rear wall of the housing component 200 has a recessed seal receiving portion 217. Figure 3 It can be seen that the front wall 211 , the side walls 210 and 212 and the rear wall enclose the contact space 218 .

[0037] exist Figure 4 and Figure 5 1 shows a converter 100 having a base part 101 with a front side and a rear side. The base part 101 has a cylindrical geometry with a surrounding cylindrical side wall 102. Actuating elements 106, 107 and 109 are arranged on the rear side of the base part 101. The actuating elements 106, 107 and 109 are designed as stable cams and can be moved as shown in FIG. Figure 5 1. The molded part has a stop 110. The driving member 103 is molded on the front side of the base member 101. The driving member 103 has a flattened portion on the opposite side, such as Figure 4 Furthermore, two fixing elements 104 are integrally formed on the base part 101 , which fixing elements have latching projections 105 at their free ends.

[0038] Figure 6 The switch element 300 is shown. The switch element has a base body 301, which has an operating surface 302. The operating surface 302 can be manually operated. A slide 303 is molded on the base body 301. The slide 303 has a recess 304. The converter 100 can be inserted into the recess 304, as will be explained in detail later. The recess 304 has an operating element receptacle 305, 306. The side surfaces of the recess 304 form a mating surface 307. Figure 1 It can be seen that the slide 303 has a guide 308 on the opposite side. A spring receiving portion 309 is also formed in the base body 301. Figure 6 It can be seen that the converter 100 can be inserted into the recess 304 with its molded part carrying the actuating elements 106, 107 and 109. Figure 6 In the position shown, the first actuating element 106 engages in the actuating element receptacle 306 . The stop 110 of the converter 100 bears against the counter surface 307 . The third actuating element 109 bears against the main body region of the receptacle 304 opposite the actuating element receptacle 306 .

[0039] The switch element 300 can be connected to the housing part 200 by means of the converter 100 and the spring 50. To this end, the spring 50 is first inserted into the spring receiving portion 309 of the switch element 300, as shown in FIG. Figure 1 As can be seen. Then, the operating element 300 is pushed into the sliding guide formed between the bottom wall 201 and the wall element 205 with its slider 303. Here, the guide 308 is inserted into the guide 209 of the housing part 200. The slider 303 starts the insertion movement from the side with the front wall 211 of the housing part 200. During the insertion, the spring 50 is pushed into the spring support 214. Therefore, the insertion movement of the switching element 300 is performed against the prestress of the spring 50. As a result, the slider 303 is pushed into the housing part 200 until the recess 304 of the switching element 300 is flush with the notch 202 of the housing part 200. At this time, the converter 100 can be pushed through the bottom wall 201 from the outside of the housing through the notch 202. This is achieved by making the notch 202 substantially imitate the cross-sectional shape of the converter 100. When the converter 100 is installed in the housing part 200, the converter 100 rests with its circumferential side wall 102 against the cylindrical bearing receptacle 206, and the base part 101 with its front side strikes the shoulder gap between the two bearing receptacles 206 and 207. The driver 103 engages through the bearing receptacle 206. When the switching element is relieved when the converter 100 is installed, the converter 100 rotates in the rotary bearing formed by the bearing receptacles 206, 207 and the cylindrical side wall 212, and the converter 100 occupies a position relative to the switching element 300. Figure 6 In order to securely fasten the converter 100, an adjuster 400 is used. Figure 7 and Figure 8 4 and 5. The regulator 400 is shown in the figures. As can be seen in these figures, the regulator 400 is configured as a rotating body. The regulator has a contact support 401, from which a cylindrical protrusion 402 protrudes centrally. A receiving portion 403 is machined in the contact support 401. There is also a positioning component 404 in the form of a hole in the contact support. The regulator 400 is surrounded by a cylindrical peripheral wall 405. A driver receiving portion 407 is machined into the regulator 400 in the area of ​​its rear side 406. Here, the driver receiving portion 407 is implemented as having two lateral opposite flattened portions. A penetration portion 408 is also provided in the regulator, which forms a snap-on receiving portion 409. The rear side 406 of the regulator 400 forms a sliding surface 410.

[0040] In order to secure the converter 100 installed in the housing part 200, the adjuster 400 is inserted with its rear side 406 into the contact space 218 of the housing part 200 from the front. In this process, the cylindrical projection 411 molded onto the rear side 406 engages through the bearing receptacle 207. During this installation process, the fixing element 104 reaches into the penetration 408 in the region of its latching projection 105. At the end of the installation movement, the latching projection 105 engages from behind the opposite latching receptacle 409 of the adjuster 400. This results in a rotationally fixed correspondence between the adjuster 400 and the converter 100, so that the opposite flattened portion of the entrainment member 103 rests on the flattened portion in the entrainment receptacle 107. The sliding surface 410 of the adjuster 400 rests on the inner side of the wall element 205 of the housing part 200.

[0041] Finally, the regulating contact 30 can be installed on the contact support 401 of the regulator. Fig. 9 . The regulating contact has a contact element 31, which transitions into a support part 33 via a connecting section 32. In the area of ​​the support part 33, a bent protrusion 34 protrudes on the lower side. The regulating contact 30 is made of a spring plate. The regulating contact 30 can be inserted into the receptacle 403 with its connecting section 32. Here, the protrusion 34 engages in the positioning part 404 of the regulator 401. In this way, an exact matching of the regulating contact 30 and the regulator 400 is achieved. Fig. 9 The dotted line schematic diagram in FIG. 3 shows the basic position of the spring-opening of the adjusting contact 30. In the state of complete installation, the adjusting contact 30 occupies Fig. 9 The position is shown by the solid line. This generates a contact spring force. Fig.10 2 shows a structural unit consisting of a housing part 200 , a converter 100 , a regulator 400 , a switching element 300 and a regulating contact 30 .

[0042] The circuit board 10 can now be installed in the housing part thus preassembled. The circuit board 10 has a conductor track on its side equipped for the adjustment contact 30, which together with the adjustment contact 30 configured as a sliding contact forms an ohmic potentiometer. The circuit board 11 has other contact elements on its side facing away from the contacts, which will be explained in detail later. The connecting wire 13 is soldered to the circuit board 10. The connecting wire 13 is guided through the seal 12. The circuit board 10 has a recess 11 on the opposite side. The circuit board 10 can be pushed onto the circuit board holder 216 of the housing part 200 by means of the recess 11. The seal 12 is installed in the seal receiving portion 217 of the rear wall of the housing (see Figure 3 ) In the circuit board 10, the adjustment contact 30 can be brought into Fig. 9 In the clamped position shown (solid line diagram), at the same time, the contact elements 31 on the underside of the printed circuit board 10 exert a force on the corresponding conductor tracks.

[0043] exist Fig.11 and Fig.12 The housing upper part 600 is shown in FIG. The housing upper part 600 has a bottom 601. Two opposite side walls 602, a front wall 603 and a rear wall 604 are molded on the bottom 601. The bottom 601, the side walls 602, the front wall 603 and the rear wall 604 limit the contact space, which completes the contact space 218 of the housing part 200. A spring support 605 for the spring 50 is molded onto the housing upper part 600 in the area of ​​the front wall 603. The spring support 605 has a partially hollow cylindrical support surface 606, which is placed against the outer contour of the spring 50 in order to complete the spring support 214 of the housing part 200. As shown in FIG. Fig.11 As shown, a depression 607 is formed in the bottom 601, which is closed by a surface 608. A notch 609 is machined in the surface 608. The depression 607 forms a hollow cylindrical receiving portion. A matching latching element 610 is molded on the side wall 602. A groove-shaped seal receiving portion 611 is machined in the area of ​​the rear wall 604. Fig.12 It can be seen that ribs 612 are arranged in the interior of the housing upper part. The ribs 612 are spaced apart from the rear wall 604. Thus, a spring receptacle for the spring 20 is formed between the ribs 612 and the rear wall 604. The spring 20 has two spring sections 22, which are connected to the connecting section 21. The retaining element 23 is bent at the end of the spring section 22. The spring element 20 is made of spring steel. Thus, the spring 20 can be installed in the housing upper part 600 so that the connecting section 21 is reliably accommodated in the area formed between the ribs 612 and the rear wall 604.

[0044] exist Fig.11 60 is shown in FIG. 6 , which can be connected to the housing upper part 600. The operating member 60 has a support member 61 in the shape of a circular flat plate. The flat plate forms a guide surface 62 on the side facing the housing upper part 600 (see FIG. 6 ). Fig.12 ). A driving member 63 is molded onto the support member 61. The driving member 63 has flattened portions on opposite sides. In addition, the support member 61 carries two locking elements 64 with locking protrusions 65. The operating member 60 has a protrusion 66 on its front side, by means of which the operating member 60 can be operated. The operating member 60 can be inserted into the recess 607 with its support member 61, wherein the guide surface 62 rests on the surface 608 to form a sliding guide. The cylindrical outer wall of the support member 61 forms a rotating support together with the cylindrical inner wall of the recess 607. The operating element 60 engages with its driving member 63 and the locking element 64 through the notch 609 in the upper part 600 of the housing. This situation is Fig.12 Shown in.

[0045] exist Fig.13 and Fig.14The positioning element 500 can be seen in the figure. As shown in the schematic diagram, the positioning element 500 has a front side 501. A receptacle 502 and a positioning component 503 are machined into the front side. In addition, a protruding cylindrical projection 504 is molded in the area of ​​the front side 501. The positioning element 500 has a cylindrical supporting projection 507 on its rear side. The supporting projection 507 is penetrated by a penetration 506, wherein a snap-in receptacle 505 is located in the penetration 506. Fig.14 As shown, the positioning element 500 has a positioning receptacle 509 in the region of its circumference. In the positioning receptacle, the retaining element 23 of the spring 20 can engage on opposite sides in different adjustment positions. In particular, three adjustment positions that are rotated relative to each other can be realized.

[0046] The positioning element 500 can be Fig.12 . To this end, the spring 20 is first installed in the upper part of the housing as described above. The positioning element 500 can then be installed in the upper part of the housing, wherein the supporting protrusion 507 is engaged in the notch 609. Here, the flattened portion in the area of ​​the through-portion 506 is opposite to the flattened portion of the drive member 63 of the operating member 60, so that a torsion-proof correspondence between the positioning element 500 and the operating member 60 is achieved. When the positioning element 500 is installed, the locking element 64 slides into the through-portion 506 until the locking element 64 engages the locking receptacle 505 from the rear. The installation step is thus completed. In the installed position, the sliding surface 508 rests on the inner side on the bottom 601 to form a sliding guide. As shown Fig.15 As shown, two contact elements 40 can be connected to the positioning element 500. The contact element 40 has the same basic structure as the contact element 30, so reference can be made to the previous embodiment. The contact element 40 has a contact element 41 connected to the support part 43 via a connecting section 42. The protrusion 34 extends from the support part 43. The contact element 40 can be connected to the positioning element 500 in the same way as the contact element 30 and the adjuster 400. Therefore, in order to avoid repetition, reference is made to the previous embodiment.

[0047] To complete the installation, you can now Fig.10 and Fig.15 The two pre-assembled components are connected to each other. For this purpose, the housing upper part 600 is placed on the housing part 200. Here, the mating latching element 610 is locked with the latching element 215. During the joining movement, the popped-open contact elements 30 and 40 are compressed, so that the contact element 31 abuts against the conductor path on the rear side of the circuit board 10 as described above, and the contact element 40 abuts with its contact element 41 pre-stressed by a spring against the contact mounted on the front side of the circuit board. In the installed state, the connecting line 13 is introduced into the switch housing in a sealed manner via the seal 12. Here, the seal 12 is accommodated in the seal receiving portion 611 of the housing upper part and in the seal receiving portion 217 of the housing part 200. Fig.16 The fully installed switch is shown in FIG.

[0048] When the switch element 300 is actuated, the slide 303 is thereby linearly displaced in the housing part 200. Due to the transmission mechanism, which is formed between the slide 300 and the adjuster 400 and includes the actuating elements 106, 107, 109 and the actuating element receptacles 305, 306, the linear movement of the slide 303 outside the contact space 208 can be converted into a rotational movement of the adjuster 400. When the adjuster 400 is rotated, the adjusting contact 30 on the circuit board 10 is also rotated with the adjuster 400, whereby the ohmic resistance can be set.

[0049] Three switching stages can be achieved with the aid of the operating member 60. In the middle switching stage, the two contact elements 40 are not electrically connected to each other. This achieves the cut-off position. Starting from this middle switching stage, the operating member 60 can be rotated in two directions. When the operating member 60 is rotated, the rotationally connected positioning element 500 rotates in the contact space 218. This rotation is locked with the aid of a spring 20, which is placed in the positioning receptacle 509 with its retaining element 23 in a single switching stage. The contact element 40 is also rotated with the rotation of the positioning element 500. In the switching stage shown, the contact elements 40 are electrically connected to each other via the circuit board 10, thereby enabling adjustment to the left or right.
