Summary of the Invention
Problems to be Solved by the Invention
[0004] In the relay socket, when the release lever swings from the holding position to the retracted position by the action of an operating force on the operation portion, the relay is displaced in a direction of being removed from the relay mounting portion by the contact of the contact portion. Therefore, when removing the lever mounted on the relay mounting portion, depending on the operating force applied to the operation portion, the displacement of the relay in the removal direction may become too large, and the relay may fall out of the relay socket.
[0005] An object of the present disclosure is to provide a socket capable of preventing an electronic device from falling when the electronic device is removed.

Advantages of the Invention
[0007] The socket of the above aspect includes a housing having a connection surface to which an electronic device is attached, and a lever rotatably attached to the housing about a rotation axis extending along the connection surface. The lever has an operation portion extending in a first direction with one end in the first direction exposed outside the housing, and a contact portion extending from the operation portion in a second direction and in a direction approaching the connection surface and rotating about the rotation axis together with the operation portion. The housing has a regulating projection. The operation portion is configured to be rotatable about the rotation axis between a first position adjacent to a side portion of the electronic device extending in the first direction and a second position farther from the side portion than the first position. When the operation portion is in the first position, the tip portion of the contact portion faces the connection surface in the circumferential direction with respect to the rotation axis inside the housing. When the operation portion is in the second position, the tip portion faces the connection surface in the circumferential direction with respect to the rotation axis outside the housing. When the operation portion is rotated from the first position to the second position with the electronic device connected to the connection surface, the regulating projection contacts a protruding portion protruding from the side portion of the electronic device toward the operation portion at the second position, and restricts the movement of the electronic device in the first direction and away from the connection surface. With such a configuration, it is possible to realize a socket capable of preventing the electronic device from falling when removing the electronic device.

Mode for Carrying Out the Invention
[0009] Hereinafter, an example of the present disclosure will be described with reference to the accompanying drawings. In the following description, terms indicating a specific direction or position (for example, terms including "up", "down", "right", and "left") are used as necessary. However, the use of these terms is for facilitating the understanding of the present disclosure with reference to the drawings, and the technical scope of the present disclosure is not limited by the meanings of these terms. Further, the following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or its uses. Furthermore, the drawings are schematic, and the ratios of each dimension etc. do not necessarily match the actual ones.
[0010] As shown in FIG. 1, the socket 1 according to an embodiment of the present disclosure includes a housing 10 and a lever 20 rotatably attached to the housing 10.
[0011] The housing 10 has a connection surface 11 to which an electronic device (for example, an electromagnetic relay) 100 is attached. In the present embodiment, as an example, the housing 10 has a thin plate shape and has a mounting portion 12 disposed on the side opposite to the connection surface 11 in a first direction (for example, the Z direction) intersecting the connection surface 11. The connection surface 11 is disposed substantially at the center of the housing 10 in the width direction (for example, the X direction) of the housing 10, which is a second direction intersecting the first direction Z. The housing 10 is attached to an external device (not shown) such as a control panel via the mounting portion 12. A plurality of wiring connection portions 13 are provided on both sides of the connection surface 11 of the housing 10 in the second direction X. External wiring (not shown) is connected to each wiring connection portion 13.
[0012] As shown in FIGS. 2 and 3, the housing has a regulating projection 14. When the operating portion 21 of the lever 20 described later is rotated from a first position P1 (see FIG. 2) to a second position P2 (see FIG. 3) in a state where the electronic device 100 is connected to the connection surface 11, the regulating projection 14 contacts the protruding portion 110 of the electronic device 100 at the second position P2 and restricts the movement of the electronic device 100 in the first direction Z and in a direction away from the connection surface 11.
[0013] In this embodiment, the restricting projection 14 is provided on a pair of support wall portions 15 of the housing 10. As shown in FIGS. 2 and 3, the pair of support wall portions 15 are arranged adjacent to the connection surface 11 in the second direction X. Each support wall portion 15 is plate-shaped and extends in the first direction Z along a plane including the first direction Z and the second direction X. As shown in FIG. 4, a gap 16 in which the lever 20 is arranged is provided between the pair of support wall portions 15 in the housing thickness direction (for example, the Y direction), which is the third direction intersecting the first direction Z and the second direction X. The restricting projection 14 is arranged at the end far from the connection surface 11 in the first direction Z on one inner surface 151 of the pair of support wall portions 15 (in other words, the surface facing the other of the pair of support wall portions 15).
[0014] As shown in FIGS. 3 and 4, the restricting projection 14 is arranged to face the connection surface 11 and has an inclined surface 141 that inclines so as to approach the operation portion 21 as it moves away from the connection surface 11 in the first direction Z. In this embodiment, the restricting projection 14 is arranged farther from the connection surface 11 than the inclined surface 141 in the first direction Z and has an inclined surface 142 connected to the inclined surface 141 in the first direction Z. The inclined surface 142 inclines so as to move away from the operation portion 21 as it moves away from the connection surface 11 in the first direction Z, opposite to the inclined surface 141.
[0015] As an example, the electronic device 100 has a substantially rectangular parallelepiped shape and includes a bottom portion 101 and side portions 102. The bottom portion 101 faces the connection surface 11 when the electronic device 100 is connected to the connection surface 11. The side portions 102 extend in the first direction Z and face the operation portion 21 of the lever 20 in the second direction X when the electronic device 100 is connected to the connection surface 11. The protruding portion 110 is provided in the middle of the side portion 102 of the electronic device 100 in the first direction Z. The protruding portion 110 has an opposing surface 111 and a locking portion 112. The opposing surface is arranged to face the restricting projection 14 in the first direction Z and be capable of contacting the restricting projection 14 when the electronic device 100 is connected to the connection surface 11. The locking portion 112 is arranged to be farther from the side portion 102 than the opposing surface 111 in the second direction X and farther from the connection surface 11 than the opposing surface 111 in the first direction Z when the electronic device 100 is connected to the connection surface 11. A terminal 120 extending from the bottom portion 101 of the electronic device 100 in the first direction Z and housed inside the housing 10 is provided on the bottom portion 101 of the electronic device 100. The terminal 120 is connected to a terminal connection portion 17 provided inside the housing 10. The terminal connection portion 17 is constituted by a pair of leaf springs capable of sandwiching the terminal 120 from the second direction X, for example.
[0016] In the present embodiment, the restricting projection 14 is arranged to be farther from the connection surface 11 than the protruding portion 110 of the electronic device 100 in the first direction Z and farther from the protruding portion 110 by a length equal to or greater than the length of the terminal 120 of the electronic device 100 (in other words, the distance W1 (shown in FIG. 2) between the restricting projection 14 and the protruding portion 110 is made larger than the length W2 (shown in FIG. 3) of the terminal 120 in the first direction Z) when the electronic device 100 is connected to the connection surface 11. The distance W1 is, for example, the linear distance between the end of the restricting projection 14 closer to the connection surface 11 in the first direction Z and the opposing surface 111 of the protruding portion 110.
[0017] For example, the inclination angles θ of the respective inclined surfaces 141 and 142 are set in the range of approximately 30 degrees to approximately 60 degrees with respect to a plane perpendicular to the inner surface 151 of the support wall portion 15. Further, the height H1 (shown in FIG. 4) of the regulating projection 14 from the inner surface 151 is set in the range of approximately 0.2 mm to approximately 1.2 mm. By configuring in this way, when removing the electronic device 100 connected to the connection surface 11, after the protruding portion 110 of the electronic device 100 contacts the regulating projection 14, it can overcome the regulating projection 14, so it is easier to remove the electronic device 100 from the socket. If the height H1 of the regulating projection 14 is too high compared to the height H2 (shown in FIG. 2) of the protruding portion 110 of the electronic device 100 (for example, H1 > 1.2 mm), it may be difficult to remove the electronic device 100 from the socket 1. Also, if the height H1 of the regulating projection 14 is too low compared to the height H2 (shown in FIG. 2) of the protruding portion 110 of the electronic device 100 (for example, H1 < 0.2 mm), when removing the electronic device 100 from the socket, it may not be possible to restrict the movement of the electronic device 100.
[0018] The lever 20 is attached to the housing 10 so as to be rotatable about a rotation axis L extending along the connection surface 11. Specifically, as shown in FIG. 2, the lever 20 has an operation portion 21 and a contact portion 22.
[0019] The operation portion 21 is, for example, rod-shaped and extends in the first direction Z, and one end in the first direction Z is exposed outside the housing 10. The operation portion 21 is configured to be rotatable about the rotation axis L between a first position P1 and a second position P2. In the present embodiment, the rotation axis L is provided at the end of the operation portion 21 in the first direction Z located inside the housing 10 (in other words, the end of the operation portion 21 closer to the connection surface 11 in the first direction Z). As shown in FIG. 2, the first position P1 is a position where the operation portion 21 is adjacent to the side portion 102 extending in the first direction Z of the electronic device 100. As shown in FIG. 3, the second position P2 is a position farther from the side portion 102 in the circumferential direction (hereinafter referred to as the circumferential direction) with respect to the rotation axis L than the first position P1.
[0020] The operation unit 21 has a recess 211 that opens to a surface facing the electronic device 100 in the circumferential direction. The recess 211 is configured to accommodate the protruding portion 110 of the electronic device 100 when the operation unit 21 is located at the first position P1, and to be able to restrict the movement of the electronic device 100 in the first direction Z and away from the connection surface 11. Specifically, as shown in FIG. 5, the recess 211 has a curved portion 212 that protrudes in a direction approaching the rotation axis L in the radial direction with respect to the rotation axis L (hereinafter referred to as the radial direction) on the side surface farthest from the rotation axis L in the radial direction. In a state where the operation unit 21 is located at the first position P1, the locking portion 112 of the protruding portion 110 is located in a region formed by the curved portion 212 in the recess 211 and the bottom surface 213 of the recess 211. Thereby, when the electronic device 100 is connected to the connection surface 11, it becomes difficult for the protruding portion 110 to come out of the recess 211, so that the movement of the electronic device 100 in the first direction Z and away from the connection surface 11 can be more reliably restricted.
[0021] The contact portion 22 extends from the operation unit 21 in the second direction X and toward the connection surface 11 and rotates around the rotation axis L together with the operation unit 21. In the present embodiment, the contact portion 22 extends radially from the end portion of the operation unit 21 located in the first direction Z inside the housing 10. As shown in FIG. 2, when the operation unit 21 is located at the first position P1, the distal end portion 221 of the connection portion 22 that is far from the operation unit 21 in the second direction X faces the connection surface 11 in the circumferential direction inside the housing 10. As shown in FIG. 3, when the operation unit 21 is located at the second position P2, the distal end portion 221 of the contact portion 22 faces the connection surface 11 in the circumferential direction outside the housing 10. That is, when the operation unit 21 is rotated from the first position P1 to the second position P2 in a state where the electronic device 100 is connected to the connection surface 11, the bottom portion 101 of the electronic device 100 is pressed by the contact portion 22, and the electronic device 100 moves in the first direction Z and away from the connection surface 11.
[0022] The socket 1 can exhibit the following effects.
[0023] For example, when rotating the operation unit 21 from the first position P1 to the second position P2 to remove the electronic device 100 connected to the connection surface 11, if an excessive force is applied to the operation unit 21, the pressing force of the contact unit 22 on the electronic device 100 may become too strong, and the electronic device 100 may pop out of the socket 1. Further, when the terminal connection portion 17 of the electronic device 100 is composed of a pair of leaf springs, when removing the electronic device 100 connected to the connection surface 11, at the moment when the clamping of the terminal 120 of the electronic device 100 by the terminal connection portion 17 is released, the terminal 120 is biased by the terminal connection portion 17 in the first direction Z and in a direction away from the connection surface 11. Also in this case, there is a risk that the electronic device 100 may pop out of the socket 1.
[0024] Socket 1 includes a housing 10 having a connection surface 11 to which the electronic device 100 is attached, and a lever 20 rotatably attached to the housing 10 about a rotation axis L extending along the connection surface 11. The lever 20 has an operation portion 21 extending in a first direction with one end in the first direction exposed outside the housing, and a contact portion 22 extending from the operation portion 21 in a second direction and in a direction approaching the connection surface 11 and rotating about the rotation axis L together with the operation portion 21. The housing 10 has a regulating projection 14. The operation portion 21 is configured to be rotatable about the rotation axis L between a first position P1 adjacent to a side portion 102 of the electronic device 100 extending in the first direction and a second position P2 farther from the side portion 102 than the first position P1. When the operation portion 21 is located at the first position P1, the tip portion 221 in the second direction faces the connection surface 11 in the circumferential direction with respect to the rotation axis L inside the housing 10. When the operation portion 21 is located at the second position P2, the tip portion 221 faces the connection surface 11 in the circumferential direction with respect to the rotation axis L outside the housing 10. When the electronic device 100 is connected to the connection surface 11 and the operation portion 21 is rotated from the first position P1 to the second position P2, the regulating projection 14 contacts a protruding portion 110 protruding from the side portion 102 of the electronic device 100 toward the operation portion 21 at the second position P2, and restricts the movement of the electronic device 100 in the first direction and away from the connection surface 11. With such a configuration, for example, when removing the electronic device 100 connected to the connection surface 11, even if the terminal 120 of the electronic device 100 is biased in the first direction Z and away from the connection surface 11, a socket 1 capable of preventing the electronic device 100 from falling can be realized.
[0025] In the socket 1, the regulating projection 14 is disposed opposite to the connection surface 11 and has an inclined surface 141 that inclines so as to approach the operation portion 21 as it moves away from the connection surface 11 in the first direction. With such a configuration, when removing the electronic device 100 connected to the connection surface 11, after the protruding portion 110 of the electronic device 100 contacts the regulating projection 14, it becomes easier to overcome the regulating projection 14. As a result, a socket 1 that can prevent the electronic device 100 from falling and is easy to remove the electronic device 100 can be realized.
[0026] In socket 1, when the electronic device 100 is connected to the connection surface 11, the regulating protrusion 14 is arranged farther from the connection surface 11 than the protruding portion 110 in the first direction and is arranged at a distance greater than or equal to the length of the terminal 120 from the protruding portion 110. With such a configuration, a socket 1 that can more reliably prevent the electronic device 100 from falling can be realized.
[0027] Socket 1 can also be configured as follows.
[0028] The regulating protrusion 14 is not limited to the case where it is arranged farther from the connection surface 11 than the protruding portion 110 in the first direction and is arranged at a distance greater than or equal to the length of the terminal 120 from the protruding portion 110 when the electronic device 100 is connected to the connection surface 11. For example, as shown in FIG. 6, the regulating protrusion 14 can be arranged at an arbitrary position farther from the connection surface 11 than the curved portion 212 of the concave portion 211 of the operation portion 21 in the first direction Z.
[0029] The regulating protrusion 14 can adopt any configuration that can contact the protruding portion 110 of the electronic device 100 at the second position P2 and regulate the movement of the electronic device 100 in the first direction and away from the connection surface 11. For example, the regulating protrusion 14 may be configured in a shape without inclined surfaces 141 and 142 (for example, a substantially rectangular parallelepiped shape), or may be configured to have only the inclined surface 141 that can contact the protruding portion 110. As shown in FIG. 7, the regulating protrusion 14 may be configured to have inclined surfaces 141 and 142 that protrude and curve in a direction away from the support wall portion 15. By configuring in this way, a socket 1 that can prevent the electronic device 100 from falling and is easier to remove the electronic device 100 can be realized.
[0030] The present disclosure is applicable not only to the electronic device 100 but also to a socket to which an electronic device 100 having a protruding portion configured to be accommodatable in the concave portion 211 when the operation portion 21 is located at the first position P1 and to be contactable with the regulating protrusion 14 when the operation portion 21 is located at the second position P2 is connected.
[0031] Although various embodiments in the present disclosure have been described in detail with reference to the drawings, finally, various aspects of the present disclosure will be described. In the following description, as an example, reference numerals will also be provided.
[0032] The socket 1 according to the first aspect of the present disclosure includes a housing 10 having a connection surface 11 to which an electronic device is connected, and a lever 20 rotatably attached to the housing 10 about a rotation axis extending along the connection surface 11.

The housing 10 has a regulating projection 14 that, when the operation portion 21 is rotated from the first position P1 to the second position P2 with the electronic device connected to the connection surface 11, contacts a protruding portion protruding from the side portion of the electronic device toward the operation portion 21 at the second position P2, and restricts the movement of the electronic device in the first direction and away from the connection surface 11.
