Description

[Technical Field]

[0001] The present invention relates to a motor. [Background technology]

[0002] BACKGROUND ART Conventionally, there has been known a motor that includes a connection terminal having a contact surface that comes into contact with an external terminal connected to an external device, and a bracket that houses the connection terminal, and that is driven when the external terminal is connected to the connection terminal.

[0003] In such motors, a technique is known in which a choke coil is provided to prevent malfunctions caused by electrical noise generated when the motor is driven being transmitted to other electrical or electronic devices (see Patent Document 1).

[0004] The choke coil is fixed to the bracket, but there is a concern that the core of the choke coil may crack when the choke coil is pressed in. For this reason, the choke coil is fixed to the bracket by applying adhesive to the choke coil.

[0005] Therefore, there was a concern that if the adhesive strength weakened due to poor adhesion or deterioration over time, the choke coil would rattle or fall off. Furthermore, when manufacturing the motor, a process was required in which adhesive was applied to the choke coil, attached to the bracket, and then dried and hardened by irradiating it with ultraviolet light or over time. This increased work process and the increased material costs due to the additional adhesive resulted in increased manufacturing costs. Furthermore, the increased work process also led to a decrease in productivity. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a motor according to an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a vertical cross-sectional view of the vicinity of a bracket 5 of a motor 1 according to an embodiment that is one example of the present invention, Fig. 2 is a horizontal cross-sectional view at the position of the bracket 5 of the motor 1, and Fig. 3 is a horizontal cross-sectional view at a position of the bracket 5 of the motor 1 that is different from that in Fig. 2. Fig. 1 corresponds to the BB cross-sectional view in Fig. 2, Fig. 2 corresponds to the AA cross-sectional view in Fig. 1, and Fig. 3 corresponds to the CC cross-sectional view in Fig. 1.

[0011] In FIG. 1, some members such as support members 11 and 12, which will be described later, are not shown. 4 is a cross-sectional view of the vicinity of the bracket 5 of the motor 1 taken along the line DD in FIG. 2. In FIG. 4, the upper side a faces downward, and the lower side b faces upward.

[0012] As shown in Figures 1 to 4, the motor 1 of this embodiment includes a choke coil 2, connection terminals 3 and 4 (hereinafter, the connection terminals 3 and 4 will be referred to as the "first connection terminal 3" and the "second connection terminal 4") having contact surfaces 3a and 4a that come into contact with external terminals connected to an external device, a substrate 9 having wiring that electrically connects the choke coil 2 and the connection terminals 3 and 4, a bracket 5 on which the choke coil 2, the connection terminals 3 and 4, and the substrate 9 are mounted, and a frame 6 that fits into the bracket 5.

[0013] In the description of this embodiment, the direction of arrow a in the direction of the axis x of the motor 1 is defined as the upper side a, and the direction of arrow b is defined as the lower side b. Furthermore, in the longitudinal direction of the choke coil 2 (the directions of arrows c and d; hereinafter also referred to as the "longitudinal direction cd"), which is a direction perpendicular to the axis x, the direction of arrow c is defined as one side c of the longitudinal direction, and the direction of arrow d is defined as the other side d of the longitudinal direction. Furthermore, in the direction perpendicular to both the axis x and the longitudinal direction cd (the directions of arrows e and f; hereinafter also referred to as the "vertical direction ef"), the direction of arrow e is defined as one side e of the vertical direction, and the direction of arrow f is defined as the other side f of the vertical direction. The longitudinal direction of the choke coil 2 is also the axial direction of the choke coil, and the vertical direction of the choke coil 2 is also the radial direction of the choke coil 2.

[0014] The motor 1 includes a shaft 8 extending in the direction of the axis x. An upper side a of the shaft 8 is rotatably attached to the bracket 5 via a bearing 13 in the direction of the axis x, and the end of the upper side a protrudes beyond the upper side a of the bracket 5. Although not shown, an end of the shaft 8 on a lower side b in the direction of the axis x is rotatably attached to the frame 6 via a bearing.

[0015] A commutator 10 is attached to the shaft 8 coaxially with the shaft 8 on the lower side b of the bearing 13 in the direction of the axis x. A rotor 14 is attached to the shaft 8 coaxially with the shaft 8 on the lower side b of the commutator 10 in the direction of the axis x. The rotor 14 has a plurality of rotor cores 14b extending radially outward from the shaft 8, and coils 14a wound around the rotor cores 14b.

[0016] The bracket 5 is located on the upper side a of the motor 1 and has a tray-like shape that covers the opening of the upper side a of the frame 6. That is, the bracket 5 has a cover portion 51 on the upper side a and a side portion 52 that rises from the outer periphery of the cover portion 51 toward the lower side b. As shown in FIGS. 1 to 3, the bracket 5 is fitted into and fixed to the opening at the end of the upper side a of the frame 6.

[0017] The commutator 10 is made up of multiple metal plates (also called "segments") arranged in a circumferential direction, and when the surfaces of these metal plates come into contact with the contact portions 11b and 12b of the support members 11 and 12 described below, a direct current that generates a rotational force in the rotor 14 is supplied to the coil 14a with the direction of the current being switched appropriately.

[0018] A pair of conductive members (hereinafter referred to as "support members") 11, 12 functioning as so-called brushes each have a pair of support portions 11a, 12a and a pair of contact portions 11b, 12b. The pair of support portions 11a, 12b support the pair of contact portions 11b, 12b relative to the bracket 5. The pair of contact portions 11b, 12b are in contact with multiple metal plates of the commutator 10, and the commutator 10 is disposed between the pair of contact portions 11b, 12b.

[0019] The motor 1 includes a PTC (Positive Temperature Coefficient) thermistor 7 having a positive temperature coefficient, connecting terminals 18 and 19 (hereinafter, connecting terminal 18 and connecting terminal 19 will be referred to as the "first connecting terminal 18" and the "second connecting terminal 19") connected to the PTC thermistor 7, terminal members 15 and 16 (hereinafter, terminal member 15 and terminal member 16 will be referred to as the "first terminal member 15" and the "second terminal member 16") connected to the choke coil 2, and a commutator 10 electrically connected to the second terminal member 16 and the second connecting terminal 19.

[0020] The choke coil 2 is arranged on the side of arrow f within the bracket 5, and has one end on the connection terminal (first connection terminal 3 and second connection terminal 4) side (one side c) and the other end on the opposite side of the connection terminal (other side d). The choke coil 2 includes a coil 22 and a yoke (iron core) 21 surrounded by the coil 22. The coil 22 is wound around the outer circumferential surface of the yoke 21.

[0021] From the choke coil 2, a lead wire (hereinafter referred to as the "first lead wire") 23a is drawn out from the coil 22 toward one longitudinal side c and electrically connected to an external device not shown, and a lead wire (hereinafter referred to as the "second lead wire") 23b is drawn out from the coil 22 toward the other longitudinal side d and electrically connected to the commutator 10.

[0022] The first terminal member 15 and the second terminal member 16 are produced by forming a member (intermediate member) punched out from a single metal plate and then cutting it into pieces. Fig. 5 shows a front view of intermediate member 20 including portions 15a and 16a that will become first terminal member 15 and second terminal member 16. In Fig. 5, the upper side a faces downward and the lower side b faces upward.

[0023] The intermediate member 20 includes a portion 15a that will become the first terminal member 15, a portion 16a that will become the second terminal member 16, and a connecting portion 17 that connects the portions 15a and 16a. A portion 41b and a portion 41a that will become the second connection terminal 4 are connected to the portion 15a on the opposite side of the connecting portion 17 in this order.

[0024] Between the connecting portion 17 and the portion 15a, recesses 15b and 15c are provided on both sides in the width direction. Furthermore, between the connecting portion 17 and the portion 16a, recesses 16b and 16c are provided on both sides in the width direction.

[0025] The connecting portion 17 and the portion 15a can be separated at the recesses 15b and 15c, with the line connecting the two serving as a dividing line 151. Similarly, the connecting portion 17 and the portion 16a can be separated at the recesses 16b and 16c, with the line connecting the two serving as a dividing line 161.

[0026] Intermediate member 20 is bent at folding lines F and G so as to form a mountain fold relative to the plane of the drawing in Fig. 5 and so as to be approximately perpendicular to the plane of connecting portion 17. Also, intermediate member 20 is bent at folding line H so as to form a mountain fold relative to the plane of the drawing in Fig. 5 and so as to be approximately parallel to the plane of connecting portion 17. In this way, portion 15a and portion 16a are formed into the shapes of first terminal member 15 and second terminal member 16, respectively.

[0027] Furthermore, intermediate member 20 is bent at folding line I in a mountain fold relative to the plane of the drawing in FIG. 5 so that the angle between the plane of portion 15a and the plane of portion 41b is a narrow angle (see FIG. 6, described later; approximately 45° in FIG. 6). Then, starting from the boundary line between portions 41a and 41b, the region of portion 41a is rounded with a predetermined curvature toward the same side as the folding direction at folding line I (a mountain fold relative to the plane of the drawing in FIG. 5). In this way, portions 41a and 41b are shaped into the shape of second connection terminal 4.

[0028] The intermediate member 20 has the shapes of the first terminal member 15 and the second terminal member 16, and the support portion 12a of the support member 12 is attached to the portion 16a. Fig. 6 shows a top view (viewed from the upper side a) of the part 24 in a state where the support member 12 is attached to the intermediate member 20, and Fig. 7 shows a front view (viewed from the other side f). Fig. 6 shows the positions of the folding lines F to I along which the intermediate member 20 is folded by the folding process.

[0029] As described above, intermediate member 20 after bending includes portion 15a that will become first terminal member 15, portion 16a that will become second terminal member 16, and portions 41a and 41b that will become second connection terminal 4. By cutting along delimiting lines 151 and 161 and removing connecting portion 17, first terminal member 15, second terminal member 16, and second connection terminal 4 can be obtained as is. In the following description, regardless of whether connecting portion 17 is present or not, each portion will be referred to by the name of the respective finished part (first terminal member 15, second terminal member 16, and second connection terminal 4).

[0030] If a motor having the same configuration as motor 1 of this embodiment but not incorporating choke coil 2 is to be obtained, intermediate member 20 may be used in its original shape after bending without removing connecting portion 17. By doing so, the portion where choke coil 2 was previously incorporated becomes directly connected, completing an electrical circuit and allowing the motor to function as one not incorporating a choke coil.

[0031] The second terminal member 16 includes a foot portion 162, an attachment portion 163, and an overhang portion 164. The foot portion 162 is an engagement portion that engages with the bracket 5 on an upper side a. The support portion 12a is attached to the attachment portion 163 on a lower side b. The overhang portion 164 continues from the attachment portion 163 to the other side f on the lower side b, and is bent to one side c to overhang from the attachment portion 163. The foot portion 162 has a hook shape, and is inserted into and engaged with (fixed to) a slit-shaped insertion hole 512 provided in a surface of the cover portion 51 of the bracket 5 facing the lower side b (hereinafter referred to as the "top surface 511").

[0032] In the direction of axis x, the mounting portion 163 is continuous with a lower side b of the foot portion 162, and two holes 163b for mounting the support portion 12a are provided in the direction of axis x near the center (intermediate portion) between an end portion 163a of the lower side b of the mounting portion 163 and the foot portion 162. The support member 12 is mounted to the second terminal member 16 with a mounting fixture 163c such as a screw so that a surface 163d facing one side c of the mounting portion 163 comes into contact with a mounting surface 12a′ of the support portion 12a of the support member 12 (see FIGS. 6 and 7).

[0033] The second terminal member 16 has a protrusion 164a that protrudes toward the lower side b near the end of one side c of the protrusion 164, and an engagement portion 164b having a slit that opens toward the lower side b is formed at the end of the lower side b of the protrusion 164a.

[0034] On the other hand, the first terminal member 15 has a foot 152 on an upper side a and a protrusion 153 on a lower side b. A portion 41b and a portion 41a that become the second connection terminal 4 are connected to the upper side a of the protrusion 153 (at a position closer to the attachment portion 163) on the side opposite to the side connected to the coupling portion 17. The foot 152 has a hook shape, and is inserted into and engaged with (fixed to) an insertion hole 513 provided in the top surface 511 of the bracket 5.

[0035] The first terminal member 15 has a recess 153b near an end 153a on the lower side b of the protrusion 153. The recesses 153 are provided on both sides of the first terminal member 15 in the width direction. In this manner, a part 24 is obtained in which the support member 12 is attached to the intermediate member 20, as shown in FIGS.

[0036] The component 24 is attached to the bracket 5 either as it is, or as two components, a component including the first terminal member 15 and the second connecting terminal 4 and a component including the second terminal member 16 and the support member 12, after cutting along the dividing lines 151 and 161 to remove the connecting portion 17. If the component 24 is attached to the bracket 5 as it is, it can be simply cut along the dividing lines 151 and 161 after attachment to remove the connecting portion 17.

[0037] A plurality of (two in this embodiment) holding portions 53a, 53b are provided on the top surface 511 of the bracket 5, and the choke coil 2 is held by the holding portions 53a, 53b (see FIGS. 2 and 4). The holding portions 53a, 53b are arranged as a pair in the longitudinal direction cd of the choke coil 2, and the yoke 21 protruding from both ends of the coil 22 in the choke coil 2 is held by these holding portions 53a, 53b.

[0038] In this embodiment, there are two holding portions 53a and 53b, but other holding portions for holding the outer peripheral surface of coil 22 may be provided, or holding portions for holding the outer peripheral surface of coil 22 may be provided instead of the holding portions that hold yoke 21 at both ends, or these may be combined. Also, any number of holding portions may be provided, but a plurality is preferable for stable holding of choke coil 2. To hold the choke coil, it is preferable that a holding portion is provided on top surface 511 of bracket 5, but some of the holding portions, or all of the holding portions, may be provided on a location other than top surface 511, such as side portion 52, as long as stable holding is possible.

[0039] The support member 11 has a shape that is line-symmetrical to the support member 12 with respect to a straight line parallel to the longitudinal direction cd of the choke coil 2. The support member 11 has a support portion 11a attached to the second connecting terminal 19 with a fixture 193c such as a screw. The attachment of the support member 11 to the second connecting terminal 19 is configured in the same way as the attachment of the support member 12 to the second terminal member 16.

[0040] 2, the first connecting terminal 18 is connected to the PTC thermistor 7 in addition to the second connecting terminal 19. As shown in FIG. 2, the first connecting terminal 18 includes a contact portion 181 that is in contact with the PTC thermistor 7, a conductive portion 182 that extends from the contact portion 181 to one side c, a protruding piece 183 that extends from the conductive portion 182 to the lower side b, a grounding portion 184 that branches from the conductive portion 182 to the one side c and contacts the frame 6, and a first connecting terminal 3 that branches from the conductive portion 182 to the other side d.

[0041] The grounding portion 184 is in contact with the inner surface of the frame 6 and is grounded to the frame. The first connection terminal 3 has a shape that is line-symmetrical to the second connection terminal 4 with respect to a straight line that is parallel to the longitudinal direction cd of the choke coil 2 as a reference.

[0042] A pair of the first connection terminal 3 and the second connection terminal 4 constitutes a connection terminal electrically connected to an external device. The first connection terminal 3 and the second connection terminal 4 have contact surfaces 3a and 4a that come into contact with external terminals connected to the external device.

[0043] 1 and 2, in the AA cross section, the bracket 5 and the frame 6 are fitted together, so that the frame 6 is present adjacent to the outer periphery of the bracket 5. However, in a region (for example, region J in FIG. 1) closer to the upper side a in the direction of the axis x, only the bracket 5 is present, and the frame 6 is not present. In FIG. 2, the regions indicated by dotted lines and labeled with reference numerals 54 and 55 indicate openings provided in the side portion 52 of the bracket 5 in region J closer to the upper side a than the AA cross section (hereinafter referred to as "opening 54" and "opening 55").

[0044] When viewed from the outside of the bracket 5 (viewed from the tip of one side c in FIG. 2), the opening 54 opens toward the contact surface 3a of the first connection terminal 3, and the opening 55 opens toward the contact surface 4a of the second connection terminal 4. Therefore, an external terminal (not shown) connected to an external device is inserted into the bracket 5 through the openings 54 and 55 and comes into contact with the contact surfaces 3a and 4a.

[0045] 3 and 4, the substrate 9 is attached to the bracket 5 at a position closer to one side c of the bracket 5. The substrate 9 is arranged so as to cover the yoke 21 of the choke coil 2 that protrudes from the coil 22 to the one side c, the first connection terminal 3, the second connection terminal 4, and the area near the protruding piece 183 of the conductive portion 182.

[0046] The substrate 9 faces the top surface 511 of the bracket 5. The top surface 511 and the side portion 52 of the bracket 5 intersect. The yoke 21 (one end of the choke coil 2) of the choke coil 2 protruding from the coil 22 to one side c is located between the opposing surfaces of the substrate 9 and the bracket 5 (between the surface of the upper side a of the substrate 9 and the top surface 511). In this embodiment, the yoke 21 (one end of the choke coil 2) is further sandwiched between the substrate 9 and the holding portion 53 a of the bracket 5.

[0047] Two through holes 9a, 9b are provided in the substrate 9. A protruding piece 183 of the first connecting terminal 18 is inserted into the through hole 9a. By soldering the inserted protruding piece 183 that is exposed to the lower side b from the through hole 9a to the printed wiring formed on the surface of the lower side b of the substrate 9, an electrical connection is established between the circuit of the substrate 9 and the first connecting terminal 18, and the substrate 9 is fixed to the bracket 5.

[0048] The portion of the protrusion 153 of the first terminal member 15 on the end 153a side is inserted into the through hole 9b. The protrusion 153 inserted into the through hole 9a has the end 153a and the recess 153b exposed from the through hole 9a from the underside b. As shown in FIG. 3, the first lead wire 23a drawn from one end of the choke coil 2 is connected to the protrusion 153 exposed from the through hole 9a. The first lead wire 23a and the protrusion 153 are electrically connected by winding the first lead wire 23a between the pair of recesses 153b and then soldering them.

[0049] The substrate 9 is fixed to the protrusion 153. The substrate 9 and the protrusion 153 are fixed together by soldering the protrusion 153 to wiring formed on the surface of the lower side b of the substrate 9. This soldering electrically connects the circuit of the substrate 9 to the first terminal member 15, and also fixes the substrate 9 to the bracket 5.

[0050] 3, the second lead wire 23b drawn out from the other end of the choke coil 2 is connected to the second terminal member 16. The second lead wire 23b and the second terminal member 16 can be fixed and electrically connected by fitting the first lead wire 23a into the gap of the engaging portion 164b and then crimping the protruding portion 164a with pliers or the like.

[0051] According to the present embodiment, one end of the choke coil 2 is sandwiched between the substrate 9 and the retaining portion 53a of the bracket 5, allowing the choke coil for eliminating electrical noise to be fixed with a simple configuration. This eliminates the need for adhesive to fix the choke coil, or requires only a small amount of adhesive, simplifies the work process, and reduces material costs by reducing or eliminating the use of adhesive, thereby reducing manufacturing costs. Furthermore, simplifying the work process also leads to improved productivity.

[0052] Generally, when connecting an external terminal connected to an external device to the connection terminals (first connection terminal 3 and second connection terminal 4), shock or vibration may be applied, causing the choke coil 2 to move and potentially causing it to become disconnected from the terminal members (first terminal member 15 and second terminal member 16). However, according to this embodiment, by pressing the end of the choke coil 2 on the connection terminal side with the substrate 9, the movement of the choke coil 2 can be prevented and the connection between the terminal members and the choke coil 2 can be maintained.

[0053] The substrate 9 is normally provided for driving the motor 1, and in this embodiment, it is also used to hold the choke coil 2, thereby effectively fixing the choke coil 2 without adding any new components.

[0054] While the motor of the present invention has been described above with reference to preferred embodiments, the motor of the present invention is not limited to the configuration of the above embodiments. For example, in the motor 1 of the above embodiment, one end of the choke coil 2 is sandwiched between the substrate 9 and the retaining portion 53a of the bracket 5. However, the present invention is not limited to this. For example, the substrate 9 may be fixed to the bracket 5 with a gap between the one end of the choke coil 2. By positioning the choke coil 2 between the opposing surfaces of the substrate 9 and the bracket 5, it is possible to prevent the choke coil 2 from falling off or moving, thereby suppressing movement of the choke coil 2 and maintaining the connection between the terminal member and the choke coil 2.

[0055] In addition, those skilled in the art can appropriately modify the motor of the present invention in accordance with conventionally known knowledge. As long as such modifications still comprise the configuration of the present invention, they are of course included in the scope of the present invention. [Explanation of symbols]
