Detailed implementation mode

[0058] Hereinafter, with reference to the drawings, the implementation modes of the in-vehicle device and the solenoid device of the present utility model will be described in detail. However, in order to avoid making the following description unnecessarily long and to make it easy for those skilled in the art to understand, sometimes detailed descriptions that are more than necessary are omitted. For example, sometimes detailed descriptions of well-known matters and repeated descriptions of substantially the same structures are omitted. In addition, for the elements described in the previously described drawings, sometimes appropriate references are made in the description of the subsequent drawings.

[0059] In each of the drawings described below, for the convenience of explanation of directions, the XYZ coordinate axes are shown, and the same directions are represented in any of the drawings described below.

[0060] Figure 1 and Figure 2 It is a perspective view showing the appearance of the solenoid device. Figure 1 It shows the appearance of one side of the solenoid device, Figure 2 It shows the appearance of the other side of the solenoid device. Figure 3 It is a cross-sectional view showing the internal structure of the solenoid device.

[0061] The solenoid device 100 is used, for example, as an in-vehicle device, and includes a device main body 101 and a connector 102.

[0062] The device main body 101 has a generally cylindrical outer shape extending in the X-axis direction, and has an output shaft 140 on the front side in the X-axis direction. The device main body 101 is mounted on a vehicle and is electrically connected to a wire harness on the vehicle side. The device main body 101 includes a front face cover 110, a rear face cover 120, and a peripheral face cover 130. The front face cover 110 covers the front of the device main body 101, and the output shaft 140 penetrates through the central portion of the front face cover 110 and protrudes forward. The output shaft 140 is driven in the front-rear direction in the X-axis direction. The rear face cover 120 covers the rear of the device main body 101, and the peripheral face cover 130 covers the peripheral surface of the device main body 101. The front face cover 110, the rear face cover 120, and the peripheral face cover 130 are made of metal, for example.

[0063] The device main body 101 includes a coil 150, a bobbin 160, a core 170, and a plunger 180 inside.

[0064] The coil 150 is wound around the outer periphery of the hollow bobbin 160. The core 170 is made of a magnetic material and is fixed to the inner surface of the bobbin 160. By energizing the coil 150, a magnetic field is induced in the core 170.

[0065] The plunger 180 is integrated with the output shaft 140 and moves back and forth in the X-axis direction by the magnetic field generated by the core 170.

[0066] The bobbin 160 has a coil portion 161 around which the coil 150 is wound and a connector mounting portion 162 to which the connector 102 is mounted. The connector mounting portion 162 is provided at a portion in the Z-axis direction, for example, around the bobbin 160.

[0067] The connector 102 is mounted on the device main body 101 and electrically connects a wire harness (not shown in the figure) and the device main body 101. Specifically, the connector 102 is fixed to the connector mounting portion 162 of the bobbin 160 by a snap, and has an outer shape that protrudes from the peripheral surface of the device main body 101 in the Z-axis direction and extends in the X-axis direction, for example. The connector 102 has a wire harness mounting portion 201 on the rear side in the X-axis direction, for example, and a vehicle-side wire harness is mounted on the wire harness mounting portion 201. The connector 102 electrically connects the wire harness and the coil 150.

[0068] The looseness between the connector 102 and the bobbin 160 is required to be within the tolerances required in the design. If the looseness is large, for example, poor installation of the wire harness may sometimes occur. Therefore, in the solenoid device 100 of the present embodiment, a mounting structure for suppressing the looseness between the connector 102 and the bobbin 160 is used.

[0069] Figures 4 to 7 It is a diagram showing the mounting structure of the connector 102 and the bobbin 160. Figure 4 It is a perspective view showing the state after removing the front face cover 110, Figure 5Indicates an exploded three-dimensional view, Figure 6 Indicates a partially enlarged view, Figure 7 Indicates a sectional three-dimensional view.

[0070] The connector 102 is press-fitted from the + side to the - side in the Z-axis direction with respect to the connector mounting portion 162 of the bobbin 160 and is snap-fitted. In the following description, the - direction of the Z-axis may sometimes be referred to as the "mounting direction". In addition, different from the front-rear direction of the device main body 101, sometimes with the mounting direction as a reference, the - direction of the Z-axis is referred to as the front of the mounting direction, and the + direction of the Z-axis is referred to as the rear of the mounting direction.

[0071] After the connector 102 is mounted on the bobbin 160, the peripheral mask 130 is fixed as a part of the device main body 101. The peripheral mask 130 covers the coil portion 161 and the coil 150 of the bobbin 160, and presses the connector 102 as described later to prevent separation from the bobbin 160.

[0072] The connector 102 includes legs 202 extending in the mounting direction. In the present embodiment, as an example, two legs 202 are provided so as to sandwich the connector mounting portion 162 of the bobbin 160. The legs 202 are made of resin, for example, and have flexibility in the Y-axis direction orthogonal to the mounting direction. In the following description, the Y-axis direction may sometimes be referred to as the orthogonal direction with respect to the mounting direction.

[0073] The connector mounting portion 162 of the bobbin 160 has a guide wall 301 that guides the legs 202 in the mounting direction. The guide wall 301 extends along the XZ plane. In addition, "along" is not limited to the case of parallel, and means allowing inclination, unevenness, and bending within a range that is not problematic in practice.

[0074] The legs 202 have a fitting hole 203, an inclined surface portion 204, and a covered portion 205, and a fitting protrusion 302 projects from the guide wall 301.

[0075] The fitting hole 203 is a hole into which the fitting protrusion 302 is fitted.

[0076] The inclined surface portion 204 is located on the front side (the - direction side of the Z-axis) in the mounting direction with respect to the fitting hole 203 and faces the guide wall 301 side. That is, the inclined surface portion 204 is provided at the front portion of the leg 202 in the mounting direction, and is inclined in the direction of separating from the guide wall 301 as it faces the front in the mounting direction, and faces the guide wall 301 side.

[0077] The covered portion 205 is located on the rear side (the + direction side of the Z-axis) in the mounting direction with respect to the fitting hole 203 and projects to the side opposite to the guide wall 301 (the + direction side of the Y-axis).

[0078] The engaging protrusion 302 protrudes along the orthogonal direction with respect to the mounting direction, and the front side surface 303 located on the front side of the mounting direction and the rear side surface 304 located on the rear side of the mounting direction each extend along the orthogonal direction with respect to the mounting direction. In other words, the engaging protrusion 302 has side surfaces 303 and 304 that extend along the orthogonal direction before and after in the mounting direction.

[0079] On the connector 102, at a position on the rear side in the mounting direction relative to the plurality of legs 202 and between the plurality of legs 202 in the orthogonal direction (Y-axis direction) with respect to the mounting direction, a rib 206 that extends along the X-axis direction and protrudes in the mounting direction is provided. On the other hand, on the connector mounting portion 162 of the wire tube 160, a groove 305 that extends along the X-axis direction and is recessed in the mounting direction and into which the rib 206 is fitted is provided.

[0080] Figures 8 to 10 It is a diagram showing details of the mounting based on the snap fit.

[0081] Figure 8 It shows a cross-sectional view in the separated state, Figure 9 It shows a cross-sectional view in the combined state, Figure 10 It shows a partial enlarged view.

[0082] When the connector 102 advances in the mounting direction relative to the wire tube 160, the legs 202 are guided by the guide wall 301, and the inclined surface portion 204 comes into contact with the engaging protrusion 302. Then, as the connector 102 advances in the mounting direction, the legs 202 climb over the engaging protrusion 302, and the legs 202 are naturally deflected.

[0083] In addition, in the present embodiment, as Figure 10 shown, the inclined surface portion 204 extends to a position where the distance h2 from the separation from the guide wall 301 is greater than the protruding amount h1 of the engaging protrusion 302 from the guide wall 301. Therefore, when the legs 202 advance in the mounting direction, the legs 202 reliably climb over the engaging protrusion 302 through the inclined surface portion 204.

[0084] Then, when the legs 202 further advance in the mounting direction, as Figure 9 shown, the engaging protrusion 302 is fitted into the engaging hole 203 of the legs 202, and the deflection of the legs 202 is restored. As a result, the connector 102 is mounted on the wire tube 160. Both the front side surface 303 and the rear side surface 304 of the engaging protrusion 302 extend along the orthogonal direction with respect to the mounting direction. Therefore, even when an external force or the like is applied to the connector 102, the edge of the engaging hole 203 does not climb over the engaging protrusion 302, and loosening of the connector 102 is suppressed.

[0085] In addition, in the present embodiment, the engaging hole 203 is a through hole extending in the direction orthogonal to the mounting direction. Therefore, the front side surface 303 and the rear side surface 304 are in contact with the inner surface of the engaging hole 203, and loosening is further suppressed.

[0086] Furthermore, when the connector 102 is mounted on the wire winding tube 160, the protrusion 206 of the connector 102 is fitted into the groove 305 of the wire winding tube 160. Therefore, tilting of the connector 102 with respect to the wire winding tube 160 can be suppressed, and loosening of the connector 102 is further suppressed.

[0087] When the peripheral mask 130 is fixed after the connector 102 is mounted on the wire winding tube 160, as Figure 9 shown, the peripheral mask 130 covers the covered portion 205 from the rear side in the mounting direction. Therefore, the connector 102 is pressed by the peripheral mask 130, can withstand strong external forces, and separation of the connector 102 from the wire winding tube 160 can be prevented.

[0088] In addition, if the engaging hole 203 is a through hole, it is easy to manufacture, but it may also be a blind hole with a bottom. In addition, the shape of the front end of the engaging protrusion 302 protruding from the guide wall 301 may be a tapered shape with chamfers or the like as long as the front side surface 303 and the rear side surface 304 are retained. If the engaging protrusion 302 is a tapered shape, it is easy to be fitted into the engaging hole 203.

[0089] In the above description, an example is shown in which the leg portion 202 and the engaging hole 203 are provided on the connector 102 side, and the guide wall 301 and the engaging protrusion 302 are provided on the wire winding tube 160 side. However, the leg portion according to the present invention may be provided on the wire winding tube 160 side, and the guide wall according to the present invention may be provided on the connector 102 side.

[0090] In addition, in the above description, as an example of the vehicle-mounted device of the present invention, a solenoid device is shown. However, the vehicle-mounted device of the present invention is not limited to the above, and the present invention can be widely applied to various devices equipped with connectors.
