1 EVENT ORGANIZED TO ENCLOSE A CIRCUIT INCLUDING ELECTRONIC COMPONENTS AND A TOOL INCLUDING ARRANGEMENT.
TECHNICAL FIELD The present invention relates to hand-held power tools, wherein the tools are controlled by electronic components mounted on a circuit board. More particularly, the invention relates to an arrangement arranged to enclose a circuit board comprising electronic components and to a tool comprising the arrangement.
TECHNICAL BACKGROUND A hand-held tool, such as a deburring hammer, includes oscillating elements to strike a chisel tool when the deburring hammer is used to break concrete or the like. During blows, shock waves are created which are transported by the chisel tool into the material to be broken. The blows also cause strong vibrations inside the bilge hammer. The vibrations can cause damage to the parts of the hammer. Therefore, the parts are usually mounted with a vibration protection in the form of, for example, rubber bushings.
An electric tool uses electronic components mounted on a circuit board to disrupt the tool's functions. The circuit board and the components mounted on the board are exposed to strong vibrations and must therefore be protected. Today, the standard wiper circuit board with the electronic components is mounted in an enclosure that is molded with stabilizing and electrically insulating materials such as epoxy. A disadvantage of this solution is that the epoxy must be removed and then recast when repairing the circuit board and the electronic components. This is both time consuming and difficult.
In view of the above, there is a need for an arrangement for a circuit board comprising electronic components, for example the above-mentioned enclosure, which facilitates repairs of the circuit board and the electronic components.
SUMMARY OF THE INVENTION An object of the present invention is to provide an arrangement for a circuit board comprising electronic components which facilitates repairs of the circuit board and of the electronic components. This object is achieved according to an aspect of the present invention by means of an arrangement arranged to enclose a circuit board comprising electronic components, comprising: a structure designed to receive the circuit board and the electronic components, a housing designed to receive the structure, a cover designed to connect to the housing, an electrical contact adapted to supply the circuit board with electricity, the electrical contact being included in at least one of the housing or cover. The arrangement is arranged to enclose the circuit board by means of the housing and the lid, the structure being designed to releasably abut at least partially against the circuit board and the electronic components.
Since the arrangement comprises the structure designed to receive the circuit board and the dielectric components, the housing designed to receive the structure and the cover designed to connect to the housing, the circuit board comprising the electronic components can be enclosed in a simple manner by means of the housing and the cover. Thereby an arrangement is obtained which can protect the circuit board comprising the electronic components against external stresses in an environment in which the arrangement is located.
The structure is designed to receive the circuit board and the electronic components, whereby the circuit board and the electronic components can be placed in the structure. In this way, the circuit board and the electronic components are protected from, for example, vibrations. Furthermore, since the structure is designed to releasably abut at least partially the counter-circuit board and the electronic components, the circuit board and the electronic components can at least partially be in contact with the structure. This contact between the circuit board and the electronic components with the structure allows self-oscillations of the circuit board and / or the electronic components to be attenuated by the structure. This provides a structure that protects the circuit board and the electronic components from natural oscillations of the circuit board and the electronic components.
In addition, the circuit board and the electronic components can be released from the structure, since the structure is designed to releasably abut at least partially against the circuit board and against the electronic components. Thus, the circuit board and the electronic components can be separated from the structure in a simple and efficient manner during, for example, repairs or recycling.
Accordingly, an arrangement for a circuit board comprising electronic components is provided which facilitates repairs of the circuit board and of the electronic components mounted on the circuit board 3 and thus the above-mentioned object is achieved.
The structure can be elastic, ie. elastically deformable. Thereby a flexible structure is obtained which can adapt to different geometric shapes of the circuit board and the electronic components.
According to certain embodiments, the structure comprises cavities, designed to receive the dielectric components and releasably abut the electronic components. Thus, the electronic components can be releasably placed in the cavities of the hose structure, which facilitates detachment of the electronic components from the structure. Consequently, the electronic components can be removed in a simple and efficient way which facilitates repairs. Furthermore, since the electronic components can be placed in the cavities, a structure is obtained which further improves the protection against, for example, vibrations and which has better damping properties with regard to natural frequencies of the electronic components.
According to certain embodiments, the cavities are arranged to close tightly against the electronic components by means of elastic deformation of the cavities upon receipt of the dielectric components. Since the cavities are arranged to close tightly against the dielectric components, a stabilization of the electronic components is achieved when the electronic components have been placed in the cavities. This reduces the risk that the electronic components end up in natural oscillations further. By means of the elastic deformation of the cavities upon receipt of the electronic components, a flexible structure is obtained which adapts to different geometric shapes of the dielectric components. Thereby an arrangement is obtained which further improves the protection against, for example, vibrations and with further improved damping properties with regard to natural frequencies of the electronic components. At least one of the cavities may be provided with elastic ribs arranged to close tightly against at least one of the electronic components upon receipt of the dielectric components. Thus, the elastic ribs may be in contact with at least one of the electronic components upon receipt of the electronic components of the cavities. This contact between the electronic components and the elastic ribs allows natural oscillations of the electronic components 4 to be damped in an effective manner. Thereby a structure is obtained with improved protection against, for example, vibrations and with improved damping properties with regard to natural frequencies of the electronic components.
According to certain embodiments, at least one of the electronic components has a first surface facing away from the circuit board and a second surface facing the circuit board, the structure being arranged to abut at least the first surface of said at least one of the electronic components. Thereby, the electronic components can be placed in the structure so that the structure abuts at least the front surface of at least one of the electronic components facing away from the circuit board. In this way, a structure is provided with a larger component abutment surface against the electronic components, which further improves damping properties of the structure with respect to natural oscillations of the electronic components.
According to certain embodiments, the structure is releasably arranged in the housing. Thus, the structure can be separated from the housing in a simple and efficient manner when, for example, a change of the structure is required. Furthermore, this allows different structures, arranged to receive different circuit boards, to be used together with the housing.
According to certain embodiments, the structure is arranged to allow a tight connection between the casing and the lid, the structure comprising a peripheral part, the lid and the casing being arranged to provide the tight connection by compression of that peripheral part of the structure. Advantageously, an arrangement is thus obtained with a tight connection between the housing and the lid, whereby a risk of unwanted substances ending up in the interior arrangement is reduced. An additional advantage of this is that the risks of damage to the circuit board and the electronic components are reduced.
The peripheral part may comprise a radial portion, the lid and the casing may be arranged to provide the tight connection by compression of the radial portion. In this way, the tight connection between the housing and the lid is improved, since the abutment surface of the structure against the housing and / or the lid is increased. An increased contact surface makes it more difficult for unwanted substances to end up inside the arrangement and thus potentially also come into contact with the circuit board and cause damage or short circuits on the circuit board.
According to certain embodiments, the peripheral part comprises an axial portion, the lid and the casing being arranged to provide the tight connection by means of compression of the detaxial portion. In the same way as with the radial portion, the tight connection between the housing and the lid is further improved, ie. by an increase in the abutment surface of the structure against the housing and / or the lid. As a result, again as well as the radial portion, the risk of unwanted substances ending up inside the arrangement and thus potentially also coming into contact with the circuit board and causing damage or short circuits on the circuit board is reduced.
According to certain embodiments, the arrangement comprises the circuit board.
According to certain embodiments, the cover comprises at least one support element arranged to support the circuit board when the cover is mounted against the housing. The support element thus has contact with the circuit board when the cover is mounted against the housing. As a result, the risk of the circuit board becoming self-oscillating is reduced. Consequently, an arrangement is obtained which in a simple and effective manner counteracts natural oscillations in the circuit board.
In a further aspect, the object is achieved by means of a tool comprising an arrangement as described herein.
BRIEF DESCRIPTION OF THE DRAWINGS Additional objects and advantages and features of the invention will become apparent from the following description of one or more embodiments given with reference to the accompanying drawings.
Fig. 1 shows an arrangement arranged to enclose a circuit board comprising electronic components, the arrangement comprising: a structure, a housing and a lid with an electrical connection separated from each other.
Fig. 2 shows the arrangement illustrated in Fig. 1, the arrangement being assembled. Fig. 3 shows the structure of Fig. 1.
Fig. 4 shows a peripheral part of the structure shown in Fig. 1 and Fig. 3.
Fig. 5 shows a tool comprising the arrangement shown in Fig. 1 and Fig. 2. 6 DESCRIPTION OF PREFERRED EMBODIMENTS The present invention is described in more detail below with reference to the accompanying drawings, in which examples of embodiments are shown. The invention should not be construed as being limited to the described examples of embodiments. In the figures, the same reference numeral is used to refer to the same or similar features throughout the application.
Fig. 1 shows an arrangement 1 arranged to enclose a circuit board 3 comprising electronic components 5. For the sake of simplicity, only a few electronic components 5 have been provided with reference numerals. The arrangement 1 comprises a single structure 7, a housing 9, a cover 11 and an electrical contact 13 adapted to supply the circuit board 3 with electricity. According to Fig. 1, the structure 7, the housing 9 and the lid 11 are shown when separated from each other. The arrangement 1 can be considered to comprise the circuit board 3 including the electronic components 5, but preferably the arrangement 1 is not considered to comprise the circuit board 3.
As illustrated in Fig. 1, the structure 7 has a shape corresponding to the shape of the dielectric components 5 arranged on the circuit board 3. The structure 7 includes cavities 15 designed to receive the electronic components 5. For the same reason as for the electronic components 5, only a few cavities 15 have provided with reference numeral. The cavities 15 can be in number as many as the dielectric components 5 mounted on the circuit board 3. Each cavity 15 has a shape corresponding to the shape of a corresponding electronic component 5. Thus the cancer circuit board 3 and the electronic components 5 are placed in the structure 7 in a simple and efficient manner. .
The structure 7 comprises a plastic material, such as polymer, thermoplastic elastomer (TPE) or the like, with non-adhesive properties. This means that the structure 7 can releasably abut at least partially against the circuit board 3 and the electronic components 5 when the circuit board 3 and the electronic components 5 have been placed in the structure 7. This allows the circuit board 3 and the electronic components 5 to be removed from the structure 7. The structure 7 is thus formed to repeatedly close tightly against the circuit board 3 and the electronic components 5, the structure being reusable. Thus, the structure 7 can be separated from the circuit board 3 in a simple and efficient manner, which advantageously takes place in, for example, repair, scrapping or recycling of the circuit board 3 and of the electronic components 5. Furthermore, an arrangement 1 is obtained arranged to enclose a circuit board 3, which arrangement 1 is lighter than the known solution with epoxy casting.
The plastic material from which the structure 7 is made is electrically insulating and has good damping properties with regard to vibrations and natural oscillations. Since the plastic material is electrically insulating, the electronic components 5 can be placed closer to the housing 9 than in a solution without a structure and which must meet the safety standard EN 60745-1. According to such a solution, an air gap of 6 mm between electronic components and the housing is required to comply with the electrical safety standard EN60745-1. Thus, with the arrangement according to the embodiments herein, less space is required with the solution without a structure. The structure 7 thus allows a shorter distance between the dielectric components 5 and the housing 9. The thickness of the structure 7 can be in the range 2 - 4 mm, depending on the material used in the structure 7.
Furthermore, the plastic material structure 7 is made of being elastically deformable, which means that the structure 7 can be elastic and thus be able to adapt to the shape of the dielectric components 5 and of the circuit board 3 through an elastic deformation of the structure 7. Furthermore, different thermal expansions of the electronic components can be handled better. of the structure 7 compared to the known solution with epoxy casting.
Since the structure 7 is designed to releasably abut at least partially against the circuit board 3 and the electronic components 5, the circuit board 3 and the electronic components 5 can be at least partially in contact with the structure 7 when the circuit board 3 and the electronic components 5 are placed in the structure 7.
When the circuit board 3 and the electronic components 5 are placed in the structure 7, inelastic deformation of the structure and in particular of the cavities 15 takes place, which causes the cavities 15 to close tightly against the electronic components 5. This contact between the circuit board 3 and the electronic components 5 with the structure 7 allows attenuation oscillations of the circuit board 3 and / or the electronic components 5 are attenuated by means of the structure 7.
As illustrated in Fig. 1, at least one of the electronic components 5 has a front surface 19 facing away from the circuit board 3 and a second surface 21 facing the circuit board 3, the structure 7 being arranged to abut at least the first surface 19 of 8. at least one of the electronic components 5. Thereby, the electronic components 5 can be placed in the structure 7 so that the structure 7 abuts at least the first surface 19 of at least one of the electronic components 5 facing away from the circuit board 3. In this way a structure 7 is provided with a larger component abutment surface against the electronic components 5, which improves damping properties of the structure 3 with respect to natural oscillations of the electronic components 5.
Fig. 1 shows that the housing 9 has a shape which substantially corresponds to the shape of the structure 7 so that the structure can fit into the housing 9 when the structure 7 is placed in the housing 9. The structure 7 is releasably arranged in the housing 9. Thus the structure 7 can be placed in the housing 9 and separated from the housing 9 in a simple and efficient manner in case of need for repairs or if necessary replacement of the structure 7 if the structure 7 has, for example, broken. Furthermore, this allows attic structures, the main shape of which corresponds to the shape of the structure 7 but which differ from the structure 7 at the level of detail, can be placed in the housing 9. This also allows the circuit board 3 to comprise various electronic components 5 which can be placed in the structure 7. The housing 9 can be made of aluminum, magnesium, plastic, polyamide or similar.
According to the embodiment illustrated in Fig. 1, the electrical contact 13 is included in the cover 11. In other embodiments, the electrical contact 13 may be included in the housing 9.
The arrangement 1 is arranged to enclose the circuit board 3 by means of the housing 9 and the cover 11. The shape of the cover 11 substantially corresponds to the shape of the circuit board 3. When the circuit board 3 including the electronic components 5 is mounted in the arrangement 1, the cancer circuit board 3 and the electronic components 5 are first placed in the structure 7 and then the circuit board 3 and the structure 7 in the housing 9 together. Mounting can also be done in a different order. For example, the structure 7 can first be placed in the housing 9 and after that the circuit board 3 and the electronic components 5 are placed in the structure 7.
The circuit board 3 can be screwed into the housing 9 by means of screws (not shown) which are passed through card openings 2 in the circuit board 3, further through structure openings 4 in the structure 7 to finally be screwed into fasteners 6 of the housing 9. For simplicity, only one card opening2 has respectively a structural opening 4 and attachment 6 are provided with reference numerals in Figs. 1. 9 After the circuit board 3 has been screwed into the housing 9, the cover 11 is mounted against the housing 9 with, for example, additional screws (shown in Fig. 2) which are passed through cover openings 8 in the cover 11 and which are screwed into further fasteners 10 of the housing 9. For this reason, only a lid opening 8 and an additional attachment 10, respectively, have been provided with reference numerals. The lid 11 can be fastened to the housing 9 by means of, for example, clamps (not shown) in combination with the additional screws or instead of these.
The lid 11 may preferably be made of plastic, such as polyamide, or of the same type of material as the casing 9.
Furthermore, as illustrated in Fig. 1, the housing 9 comprises mounting elements 12 for mounting the housing 9 to a frame (not shown) such as a frame in a tool.
Fig. 2 shows the arrangement 1 illustrated in Fig. 1. According to Fig. 2, the arrangement 1 has been assembled together by screwing together the cover 11 and the housing 9 by means of the aforementioned additional screws 14 (only the heads of these additional screws 14 are shown in the figure). For the sake of simplicity, only a few of the additional screws 14 have been provided with reference numerals.
As illustrated in Fig. 2, the cover 11 has been screwed into the housing 9 and thereby the rake circuit board 3 including the electronic components is enclosed in the arrangement 1 by means of the housing 9 and the cover 11. In this way the arrangement 1 protects the circuit board including the electronic components from the external stresses of the arrangement 1. environment, such as vibrations, high temperatures, dust, liquids or the like.
Fig. 3 shows the structure 7 according to Fig. 1. The structure 7 comprises cavities 15 which in number canvas as many as the electronic components 5 mounted on the circuit board 3 shown in Fig. 1, but the number can also be more or less than the number of electronic components. Sometimes the circuit board comprises one or more flat electronic components, ie. these electronic components do not protrude significantly from the surface of the circuit board. The circuit board includes such flat electronic components, the number of cavities may be less than the number of electronic components. If the number of cavities is more than the number of electronic components, the structure can optionally be used together with different circuit boards. For simplicity, only a few of the cavities 15 have been provided with reference numerals in Fig. 3. Each cavity 15 has a shape corresponding to the shape of a corresponding electronic component. Thus, the circuit board and the electronic components can be placed in the structure 7 in a simple and efficient manner.
As illustrated in Fig. 3, at least one of the cavities 15 is provided with elastic ribs 17. For the sake of simplicity, only a few ribs 17 have been provided with reference numerals. The elastic ribs 17 can be made of the same plastic material as the structure 7. The ribs 17 are thus elastically deformable and are arranged to close tightly against at least one of the electronic components when the circuit board is placed in the structure. 7. This occurs through said elastic deformation of the ribs 17 when the electronic components 15 are placed in the cavity or cavities 15 provided with the ribs 17. Thus, the elastic ribs 17 can come into contact with at least one of the dielectric components when said cavity or cavities 15 receives the dielectric components. This contact between the electronic components and the elastic ribs 17 allows natural oscillations of the electronic components to be damped in an effective manner. Thereby a structure 7 is obtained with improved protection against, for example, vibrations and with improved damping properties with regard to natural frequencies of the electronic components.
Fig. 4 shows a peripheral part 23 of the structure 7. The peripheral part 23 may preferably be of the same material as the rest of the structure 7. The peripheral part 23 comprises a radial portion 25. The radial portion 25 projects radially relative to an axis A through the structure. 7. The axis A is substantially perpendicular to a major plane of extension (not shown) of the structure 7. As illustrated in Fig. 4, the peripheral portion 23 also includes an axial portion 27. The axial portion 27 projects axially from the radial portion 25, i.e. substantially parallel to the axis A. According to the embodiment shown in Fig. 4, the axial portion 27 is arranged in connection with an outer end of the radial portion 25 seen in relation to the axis A.
As illustrated in Fig. 4, the housing 9 and the lid 11 are adapted to receive the radial portion 25 and the axial portion 27 in that the housing 9 and the lid 11 are designed so that when the lid 11 is screwed to the housing 9, a channel is formed between the housing 9 and the lid 11, the channel in the embodiment illustrated in Fig. 4 being in the form of a mirror image. Thus, the radial portion 25 and the axial portion 27 can be placed between the housing 9 and the lid 11 without risk of the radial portion 25 and / or the axial portion 27 slipping off. The cover 9 and the cover 11 are designed so that the distance between the cover 9 and the cover 11 along said channel 11 is less than the thickness of the radial portion 25 and the axial portion 27. In this way the cover 11 and the cover 9 are arranged to provide a tight connection between the lid 11 and the housing 9 by compression of the radial portion 25 and / or of the axial portion 27 when the lid 11 is mounted against the housing 9.
The radial portion 25 and the axial portion 27 of the peripheral part 23 of the structure 7 entail an increased abutment surface of the structure 7 against the housing 9 and / or the lid 11, which improves the tight connection between the housing 9 and the lid 11. Thereby providing a tight connection between the housing 9 and the cover 11, which makes it difficult for unwanted substances to end up inside the arrangement and thus potentially also come into contact with the circuit board 3 and the electronic components and cause damage or short circuits to the circuit board 3 and the electronic components.
As illustrated in Fig. 4, the cover 11 comprises a support element 29 arranged to support the support circuit board 3 when the cover 11 is mounted against the housing 9. According to the embodiment illustrated in Fig. 4, the support element 29 is formed as part of the cover 11, the support element 29 being made of the same material such as the lid 11. According to other embodiments, the support element 29 can be arranged as a separate part which may be of a different material than the lid 11. In such an embodiment the support element 29 is mounted at the lid 11 by means of, for example, a screw. The support element 29 thus has contact with the circuit board 3 when the cover 11 is mounted against the housing 9. As a result, risks of the circuit board 3 ending up in self-oscillation are reduced. Consequently, an arrangement is obtained which counteracts self-oscillation in the circuit board 3 in a simple and effective manner.
Fig. 5 shows a tool 31 comprising an arrangement 1 according to the embodiments described above. The tool 31 can be, for example, a deburring hammer, a single-stroke drill, a chain saw, a wall saw, etc. The tool 31 is illustrated in a stripped-down form without protective caps which can be mounted on the frame 31 of the tool.
