  The connection terminal and the contact member may be complicated in shape, which is one factor in increasing the cost.

  An object of the present invention is to reduce the cost of an actuator provided with a connection terminal that is electrically connected to a drive source or an external device and a contact member that is elastically deformed by a cam.

In order to solve the above problems, an actuator according to the present invention is electrically connected to at least one of a drive source, a cam member having a cam portion that operates by power of the drive source, and the drive source and an external device. A plurality of connecting terminals, an operating contact member having one end in contact with the cam portion, and an elastic deformation amount of the operating contact member in contact with the cam portion, the one end being disposed at a position facing one end of the operating contact member Is changed by the operation of the cam portion, so that the fixed contact member is brought into contact or non-contact with the operating contact member, and the first connection terminal and the fixed contact which are one of the plurality of connection terminals A first relay member that electrically connects the member, and a second connection terminal that is one of the plurality of connection terminals different from the first connection terminal, and the operation contact member are electrically connected A secondary relay member includes a case formed by combining a plurality of members made of resin, and the first case member to which the case has the first relay member, and at least one width direction of the second relay member And a wall portion sandwiched from both sides .

In the actuator according to the present invention, each of the fixed contact member and the operating contact member is connected to the first connection terminal or the second connection terminal via the first relay member or the second relay member. The degree of freedom in designing contact members and connection terminals is improved. That is, it leads to the cost reduction by making a contact member and a connection terminal into a simple shape. Also, by providing such a wall portion, it is possible to prevent the occurrence of problems such as poor insulation even when the distance between the first relay member and the second relay member is short.

  The working contact member, the fixed contact member, and the plurality of front connection terminals may have a linear shape.

  By using the relay member, the developed shape of the contact member and the connection terminal can be linear. That is, when the contact member and the connection terminal are obtained by press working, the layout can be performed so that the loss of the material is reduced. Therefore, the number of parts obtained per material can be increased, leading to cost reduction.

  The first connection terminal and the second connection terminal are terminals to which a connector is connected, and may be formed of a material different from that of the operating contact member and the fixed contact member.

  By using the relay member, the contact member and the connection terminal can be formed of different materials. That is, the contact member that requires elasticity and the connection terminal from which the connector is inserted / removed can be made of a material corresponding to characteristics such as durability that require each member.

  The first relay member and the second relay member are linear members, and the first relay member has one end connected to a connection hole formed in the fixed contact member and the other end connected to the first connection. One end of the second relay member is connected to the connection hole formed in the operating contact member, and the other end is connected to the second connection terminal. It is good to be connected to each in the state passed through the formed connection hole.

  By thus forming the relay member in a linear shape, the contact member and the connection terminal can be easily connected by the relay member regardless of the shape of the contact member and the connection terminal (the processing of the relay member is easy). is there). In addition, if it is such a linear shape, a connection hole can be formed in the contact member and the connection terminal, and the connection work such as soldering can be performed in a state where the relay member is passed through the connection hole. Easy. Thus, various benefits can be expected by making the relay member linear.

  Further, the case has a second case member arranged so as to face the first case member, and the second case member is formed with a pressing portion that enters between the wall portions. Good.

  By providing such a pressing portion, wobbling of the relay member inserted between the wall portions can be prevented. For example, even if the relay member is detached from the other member, it is possible to prevent the relay member from being detached from between the wall portions, so that it is possible to reduce the risk of a short circuit due to contact with another part.

  Also, one of the first connection terminal and the second connection terminal is connected to one of the input terminals of the drive source, and one of the first connection terminal and the second connection terminal and the drive source The third connection terminal, which is another connection terminal connected to the other input terminal, may have the same shape.

  By using the relay member, the connection terminal connected via the contact member and the relay member can have the same shape as another connection terminal (third connection terminal). Therefore, parts management costs and mold costs can be reduced.

  Further, two through holes of the same size are formed in one of the first connection terminal and the second connection terminal connected to one of the input terminals of the drive source and the third connection terminal, which have the same shape. It is only necessary that the input terminal of the drive source is passed through one of the two through holes, and the positioning projection provided on the case is passed through the other.

  In this way, if two through holes having the same size are formed in the first or second connection terminal and the third connection terminal having the same shape, the input terminal is passed through the outer (inner) through hole. The connection terminals can be arranged (symmetric) so that the positioning protrusions are passed through the inner (outer) terminals, and the input terminals are passed through the left (right) through-holes and the right (left) terminals. The connection terminals can also be arranged such that the positioning protrusions are passed through. That is, the degree of freedom of arrangement of the connection terminals can be increased.

  According to the actuator of the present invention, the contact member and the connection terminal can be made simple by using the relay member.

It is the figure which showed the shape of the member assumed when a fixed contact member and a 1st connection terminal are comprised integrally, and its unfolded shape.

  Hereinafter, embodiments of the present invention will be described in detail. Unless otherwise specified, the vertical direction in the following description refers to the Y-axis direction shown in FIG. 1 along the rotational axis direction of the motor 10 that is a drive source, and the side where the main body portion of the motor 10 is located. Below, let the direction which the output shaft (motor gear 120) of the motor 10 protrudes be upper. Moreover, the left-right direction (width direction) shall mean the X-axis direction shown in FIG.

  The actuator 1 according to this embodiment includes a drive source, an output member 20 having a cam portion 22 (corresponding to a cam member in the present invention), an operating contact member 30, a fixed contact member 40, and a plurality of connection terminals 51. , 52, 53, a first relay member 61, a second relay member 62, and a case 70 in which these are housed. Hereinafter, each configuration will be described with reference to the drawings.

  The drive source is the motor 10. The type of the motor does not matter. The power of the motor 10 is transmitted to the output member 20 through the gear train. The configuration of the gear train in this embodiment is as follows. The motor 10 has a motor gear 120 that rotates integrally with the rotor. The motor gear 120 meshes with the large-diameter tooth portion of the first wheel 121 that is a compound gear. The small-diameter tooth portion of the first wheel 121 meshes with the second wheel 122. In the center wheel & pinion 122, a circular space is formed on the center side of the tooth portion, and a known ratchet mechanism 1221 is constructed in this space. A third wheel & pinion 123 is fixed to a claw member constituting the ratchet mechanism 1221. That is, the rotation of one side of the center wheel & pinion 122 is transmitted to the third wheel & pinion 123, but the rotation of the other side is not transmitted to the third wheel & pinion 123. The third wheel 123 is engaged with the large-diameter tooth portion of the fourth wheel 124 which is a compound gear. The small-diameter tooth portion of the fourth wheel & pinion 124 meshes with the large-diameter tooth portion of the fifth wheel & pinion 125 that is a compound gear. The tooth portion of the sixth wheel & pinion 126 is engaged with the small diameter tooth portion of the fifth wheel & pinion 125. The output member 20 is engaged with the sixth wheel & pinion 126. This gear train is merely an example, and can be changed as appropriate as long as the power of the motor 10 can be transmitted to the output member 20.

  The motor 10 has two (plus side and minus side) input terminals 111 and 112 (feed terminals). Each of the input terminals 111 and 112 has a bifurcated projection, and is connected to a first connection terminal 51 and a third connection terminal 53 described later.

  The output member 20 is a member that is rotated by the power of the motor 10 transmitted through the gear train, and includes an output shaft portion 21 and a cam portion 22. The output shaft portion 21 is a shaft-shaped portion that protrudes upward from the upper surface of the output member 20. A drive object (not shown) is connected to the output shaft portion 21. That is, the power of the output shaft that makes a circular motion around the rotation center axis of the output member 20 is transmitted to the driven object via various transmission members or directly. The cam portion 22 is a portion including a relatively large diameter large diameter portion 221 and a relatively small diameter small diameter portion 222 formed in the circumferential direction of the output member 20. The boundary portion between the large diameter portion 221 and the small diameter portion 222 is a gentle inclined surface that connects the two.

  The working contact member 30 is a member formed of an elastic conductive material. On the other hand, the fixed contact member 40 is a member disposed on the outer side in the thickness direction of the working contact member 30. In the present embodiment, both contact members 30, 40 are made of phosphor bronze. A bent portion (portion 32 formed in a substantially “V” shape) formed on one end side of the operating contact member 30 is in contact with the cam portion 22. When the bent portion of the operating contact member 30 is in contact with the large-diameter portion 221 of the cam portion 22, the operating contact member 30 is greatly elastically deformed toward the fixed contact member 40 side and contacts one end side of the fixed contact member 40. To do. On the other hand, when the bent portion of the operating contact member 30 is in contact with the small diameter portion 222 of the cam portion 22, the amount of elastic deformation is small, and the operating contact member 30 does not contact the fixed contact member 40. That is, the small-diameter portion 222 of the cam portion 22 brings the operating contact member 30 and the fixed contact member 40 into a non-contact state, and interrupts energization through the contact members 30 and 40.

  The connection terminal is a terminal that is electrically connected to at least one of the motor 10 that is a drive source and an external device. In the present embodiment, three connection terminals, a first connection terminal 51, a second connection terminal 52, and a third connection terminal 53 are provided. These connection terminals are formed of a conductive material different from that of the working contact member 30 and the fixed contact member 40. In this embodiment, these three connection members are all made of brass.

  The first connection terminal 51 and the third connection terminal 53 sandwiching the second connection terminal 52 are connected to the plus side input terminal 111 (feeding terminal) and the minus side input terminal 112 (feeding terminal) of the motor 10, respectively. The first connection terminal 51 and the third connection terminal 53 have the same shape. Both connection terminals 51, 53 are substantially the same as the plate 73 along the plate 73 (placed on the plate 73) (hereinafter referred to as the placement portions 511, 531) that constitutes a part of the case 70. It is a substantially “L” -shaped member having a portion (hereinafter, referred to as an upright portion 512, 532) that is erected on the upper side orthogonal to each other. The mounting portions 511 and 531 are formed with two through holes 5111 and 5311 arranged in the width direction (left and right direction). Among the two through-holes 5111 and 5311, a part of the input terminals 111 and 112 of the motor 10 (one of the bifurcated parts) is passed through the one located on the inner side in the width direction. That is, the first connection terminal 51 is connected to the left through-hole 5111 with the input terminal 111, and the third connection terminal 53 is connected to the right through-hole 5311 with the input terminal 112 of the motor 10 by soldering or the like. ing. On the other hand, a positioning projection 731 formed on the plate 73 is passed through the one located outside in the width direction. That is, the first connecting terminal 51 is passed through the right through-hole 5111 and the third connecting terminal 53 is passed through the left through-hole 5311 so that the positioning projection 731 is passed through the positioning of the connecting terminal with respect to the plate 73. Thus, in this embodiment, the 1st connection terminal 51 and the 3rd connection terminal 53 are formed in the same shape, and are arrange | positioned symmetrically (being symmetrical about the plane containing the central axis of the motor 10 as a symmetry plane). Has been.

  The second connection terminal 52 is installed between the first connection terminal 51 and the third connection terminal 53. Similar to the first connection terminal 51 and the third connection terminal 53, it has an upright portion 521 that stands on the upper side substantially orthogonal to the plate 73. The upright portions 512, 521, and 532 of the first connection terminal 51, the second connection terminal 52, and the third connection terminal 53 are arranged in the width direction. The three upright portions 512, 521, and 532 arranged in the width direction are positioned inside the connector housing portion 722 formed on the upper cover 72 constituting the case 70 (see FIG. 1). That is, a connector portion into which an external connector (not shown) can be fitted is formed by the three upright portions 512, 521, 532 and the connector housing portion 722. When the external connector is fitted, the first connection terminal 51 and the third connection terminal 53 are connected to a power source (not shown), and the second connection terminal 52 is connected to an external device (control means) not shown.

  The first relay member 61 is a member that connects the fixed contact member 40 and the first connection terminal 51. The second relay member 62 is a member that connects the operating contact member 30 and the second connection terminal 52. Both relay members 61 and 62 are linear (wire-like) members formed of a conductive material. One end of the first relay member 61 is passed through a connection hole 41 that is a through hole formed on the other end side of the fixed contact member 40 (the side opposite to the side that contacts the operating contact member 30), and the other end is the first. It is passed through a connection hole 5121 which is a through hole formed on the base side of the upright portion 512 of the connection terminal 51, and is soldered in this state. That is, the fixed contact member 40 and the first connection terminal 51 are in an electrically connected state via the first relay member 61. In the present embodiment, one end of the first relay member 61 is bent, the other end that is not bent is passed through the connection hole 41 formed in the fixed contact member 40, and the other end is directly used as the first connection terminal 51. The soldering operation can be performed in a state where the bent portion is caught by the fixed contact member 40.

  In addition, since the 3rd connection terminal 53 is the same shape as the 1st connection terminal 51, although the through-hole 5321 is formed in the root side of the standing part 532 also in the 3rd connection terminal 53, the said hole is not used.

  On the other hand, one end of the second relay member 62 is passed through the connection hole 31 which is a through hole formed on the other end side of the working contact member 30 (the side opposite to the side in contact with the cam portion 22 or the fixed contact member 40). The other end is passed through a connection hole 5222 which is a through hole formed in a portion along the plate 73 of the second connection terminal 52, and is soldered in this state. That is, the operation contact member 30 and the second connection terminal 52 are in an electrically connected state via the second relay member 62. In the present embodiment, the second relay member 62 is formed in a substantially “U” (substantially “U”) shape whose both ends are bent downward, and the connection hole 31 formed in the operating contact member 30 and Both ends can be inserted into the connection hole 5222 formed in the second connection terminal 52 from above.

  As described above, the input terminal 111 of the motor 10 and the first connection terminal 51 connected to the power source are electrically connected to the fixed contact member 40 via the first relay member 61 and connected to the external device. Since the connection terminal 52 is electrically connected to the operation contact member 30 via the second relay member 62, the second connection terminal is brought into contact with the operation contact member 30 and the fixed contact member 40 by the rotation of the output member 20. The control means of the external device connected to 52 obtains an ON signal based on it. That is, when the motor 10 is driven and its power is transmitted to the output member 20 through the gear train and the cam portion 22 rotates, the contact state (ON) / non-contact state of the working contact member 30 and the fixed contact member 40. (OFF state) changes. Therefore, by appropriately setting the shape of the rotating cam portion 22 and adjusting the timing for obtaining the ON signal or OFF signal, whether the output shaft is located at a specific position or whether the motor 10 has rotated more than a predetermined amount. It is possible to detect whether or not.

  In this embodiment, since the contact member and the connection terminal are connected via the relay member in this way, the degree of freedom in setting the shapes of the contact member and the connection terminal is improved. Using this, the contact member and the connection terminal may be set so that the developed shape is a straight line. The “development shape” refers to the shape (planar shape) of the terminal when it is assumed that the bending process is not performed. “Linear” means that the developed shape is close to a straight line. Specifically, a virtual shape that connects the outermost portions in the width direction (short direction) and the length direction (longitudinal direction) in the expanded shape is assumed, and the outer shape of the expanded shape is surrounded by the rectangle. The area of the portion (R) obtained by subtracting the portion to be removed is a shape that is smaller than the area of the portion (U) surrounded by the outer shape of the developed shape.

  The working contact member 30, the fixed contact member 40, the first connection terminal 51 (the third connection terminal 53 has the same shape), and the developed shape (U) of the second connection terminal 52 are as shown in FIG. The area of all the developed shapes is larger than the area of the portion (R) obtained by subtracting the portion (U) surrounded by the outer shape of the developed shape from the quadrangle (Q) hypothesized in the above procedure. That is, the developed shape of all the members is “linear”.

  FIG. 9 shows an example of a member assumed when the fixed contact member 40 and the first connection terminal 51 are integrally formed without using the relay member. In addition, the part shown by 90 in FIG. 9 is a part which exhibits the function similar to the fixed contact member 40, and the part shown by 91 in FIG. 9 is a part which exhibits the function similar to the 1st connection terminal 51. . The area of the developed shape of this member is smaller than the area of the portion (R ′) obtained by subtracting the portion (U ′) surrounded by the outer shape of the developed shape from the virtual quadrangle (Q ′) obtained in the above procedure. That is, the developed shape of such a member is not “linear”.

  Thus, in this embodiment, since the contact member and the connection terminal are connected via the relay member, the developed shape of the contact member and the connection terminal can be “linear”. If “linear” is used, the layout can be made so as to reduce the loss of material when forming a terminal by pressing, so the number of parts obtained per material can be increased, leading to cost reduction.

  The case 70 is a resin member that houses the above-described members that constitute the actuator 1 according to the present embodiment. The case 70 in this embodiment includes a lower cover 71 having a space formed inside, an upper cover 72 (corresponding to a second case member in the present invention) having a space formed inside, and the lower cover 71 and the upper cover. It has a plate 73 (corresponding to the first case member in the present invention) that partitions the space formed by the cover 72 (partitions into a lower space and an upper space). The motor 10 and the gear train are accommodated in the lower space. A part of the sixth wheel & pinion 126 protrudes into the upper space through a through hole formed in the plate 73, and the output member 20 is engaged with a part thereof. That is, the output member 20 is disposed in the upper space. In accordance with this, the operating contact member 30, the fixed contact member 40, the first relay member 61, the second relay member 62, the first connection terminal 51, the second connection terminal 52, and the third connection terminal 53 are also in the upper space. Is arranged. A part of the input terminals 111 and 112 of the motor 10 protrudes into the upper space through a through hole formed in the plate 73, and the protruding part is a through hole 5111 of the first connection terminal 51 and a third connection terminal. 53 is passed through 53 through-holes 5311.

  The plate 73 is formed with a wall portion 732 in addition to the positioning hole described above. The wall portion 732 is a portion in which two linear protrusions protruding upward from the upper surface of the plate 73 are arranged in parallel at a predetermined interval. Part of the second relay member 62 at a portion connecting the end portions connected to the operating contact member 30 and the second connection terminal 52 is inserted into the space between the wall portions 732. That is, the wall portion 732 sandwiches the second relay member 62 from both sides in the width direction (the width direction of the second relay member 62).

  An upper cover 72 that is disposed so as to face the plate 73 and covers the contact members 30, 40, the connection terminals 51, 52, 53, and the relay members 61, 62 together with the plate 73 can be attached to the lower cover 71. It is configured. On the inner bottom surface of the upper cover 72, a pressing portion 721 that is a linear protrusion protruding downward is formed (see FIG. 7). When the upper cover 72 is attached to the lower cover 71, the pressing portion 721 enters between the wall portions 732 formed on the plate 73. That is, the second relay member 62 inserted between the wall portions 732 is positioned so as to be pressed from above. Therefore, a part of the second relay member 62 inserted between the wall portions 732 is surrounded by the main body portion of the plate 73, the wall portion 732, and the pressing portion 721.

  In addition, not only the second relay member 62 but also a wall portion 732 sandwiching the first relay member 61 may be formed on the plate 73. In this case, a pressing portion 721 that enters between the wall portions 732 sandwiching the first relay member 61 may be separately formed on the upper cover 72.

  According to the actuator 1 according to the present embodiment described above, the following operational effects are achieved.

  The actuator 1 is configured such that each of the operating contact member 30 and the fixed contact member 40 is connected to the first connection terminal 51 or the second connection terminal 52 via the first relay member 61 or the second relay member 62. Therefore, the degree of freedom in designing the contact members 30, 40 and the connection terminals 51, 52, 53 is improved. That is, the contact members 30, 40 and the connection terminals 51, 52, 53 have a simple shape, which leads to cost reduction.

  Specifically, like the contact members 30 and 40 and the connection terminals 51, 52, and 53 in this embodiment, the developed shape of these members can be linear. Thereby, when the contact members 30, 40 and the connection terminals 51, 52, 53 are obtained by press working, the layout can be made so that the loss of the material is reduced, so that the number of parts obtained per material can be increased. This leads to cost reduction.

  Moreover, if the said relay member is used, the contact members 30 and 40 and the connection terminals 51 and 52 (53) can be formed with a different material. That is, the contact members 30 and 40 that require elasticity and the connection terminals 51 and 52 (53) from which the connectors are inserted and removed can be made of a material corresponding to characteristics such as durability that each member is required. . In the present embodiment, the contact members 30 and 40 that require elasticity are made of phosphor bronze, and the connection terminals 51 and 52 (53) that are durable enough to withstand insertion and removal of the connector are made of brass.

  Further, since the relay members 61 and 62 are linear, the contact members 30 and 40 and the connection terminals 51 and 52 connected via the relay members 61 and 62 are formed by the relay members 61 and 62 regardless of the shape. The contact members 30 and 40 and the connection terminals 51 and 52 can be easily connected (processing of the relay members 61 and 62 is easy). In addition, such linear relay members 61 and 62 are connected by soldering or the like in a state where the linear relay members 61 and 62 are passed through the connection holes 31, 42, 5121, 5222 formed in the contact members 30, 40 and the connection terminals 51, 52. Since the work can be performed, the work is easy.

  Further, the plate 73 constituting the case 70 is formed with wall portions 732 sandwiching the second relay member 62 from both sides in the width direction, and therefore, insulation failure between the first relay member 61 and the second relay member 62 is formed. The occurrence of problems such as these can be prevented.

  Further, since the upper cover 72 constituting the case 70 is formed with a pressing portion that enters between the wall portions 732, the wobbling of the second relay member 62 inserted between the wall portions 732 is prevented. be able to. For example, even if the second relay member 62 is detached from the second connection terminal 52 or the operating contact member 30, the second relay member 62 does not come out of the wall portion 732. It is possible to reduce the risk of short circuit due to the above.

  The first connection terminal 51 connected to the input terminal 111 of the motor 10 has the same shape as the third connection terminal 53 connected to the input terminal 112 of the motor 10. That is, in this embodiment, since the first connection terminal 51 and the fixed contact member 40 are connected via the first relay member 61, the shape of the first connection terminal 51 is not connected to the contact members 30 and 40. This can be the same as the third connection terminal 53, and the part management cost and the mold cost can be reduced.

  The first connection terminal 51 and the third connection terminal 53 having the same shape are formed with two through holes 5111 and 5311 having the same size, and one of the two through holes 5111 and 5311 has a motor 10. The input terminals 111 and 112 are passed through, and a positioning projection 731 provided on the plate 73 is passed through the other. That is, if two through holes 5111 and 5311 having the same size are formed in the first connection terminal 51 and the third connection terminal 53 having the same shape, the outer (inner) through hole 5111 is formed as in this embodiment. , 5311, and the input terminals 111 and 112 are passed through, and the positioning projections 731 are passed through the inner (outer) terminals. The connection terminals 51 and 53 can be arranged such that the input terminals 111 and 112 are passed through the through holes 5111 and 5311 and the positioning protrusion 731 is passed through the right (left) terminal. That is, the degree of freedom of arrangement of the connection terminals 51 and 53 can be increased.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

  In the above embodiment, the first connection terminal 51 is connected to the fixed contact member 40 via the first relay member 61, and the second connection terminal 52 is connected to the operating contact member 30 via the second relay member 62. However, the correspondence can be changed as appropriate. For example, the positional relationship between the operating contact member 30 and the fixed contact member 40 may be reversed (the type of the contact member to which the connection terminal is connected via the relay member is reversed). Therefore, in the said embodiment, although the 1st connection terminal 51 connected to the fixed contact member 40 via the 1st relay member 61 demonstrated that it was the same shape as the 3rd connection terminal 53, via a relay member The connection terminal connected to the working contact member side may have the same shape as the third connection terminal 53. That is, one of the connection terminals whose design flexibility is improved by being connected to the contact member via the relay member is a connection terminal that is not connected to the relay member (contact member) (the third connection terminal 53 in the above embodiment). As long as the shape is the same.
