DETAILED DESCRIPTION OF THE INVENTION

[0009] An example of the present disclosure will be described below with reference to the accompanying drawings. The following description is merely exemplary 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 the dimensions and the like do not necessarily correspond to reality.

[0010] As shown in FIG. 1, a socket 1 of the present disclosure includes a housing 10, a lever 20 rotatably attached to the housing 10, and a restricting member 30.

[0011] As shown in Fig. 2, the housing 10 has a first wall 11 having a connection surface 111 to which an electronic device 50 including an electromagnetic relay is connected, and a second wall 12. In this embodiment, the housing 10 has a thin plate shape and includes a housing body 101 having an opening 103 at one end in the thickness direction (for example, the Y direction), and a lid 102 that closes the opening 103 of the housing body 101. Figs. 2 to 4 show the socket 1 with the lid 102 removed.

[0012] 1, the first wall 11 is located approximately at the center of the width direction (e.g., X direction, hereinafter referred to as the first direction) of the housing main body 101. The first wall 11 extends in the first direction X and has a thickness along the height direction (e.g., Z direction) of the housing 10. The connection surface 111, for example, constitutes a part of the outer surface of the housing main body 101 and extends in the XY directions. The connection surface 111 is provided with an opening (not shown) capable of accommodating a contact portion 22 of the lever 20 (described later) and a plurality of openings (not shown) capable of accommodating terminals 120 protruding from the electronic device 50.

[0013] 2, the second wall portion 12 is positioned with a gap 16 between it and the first wall portion 11 in a first direction X along the connection surface 111. A lever 20 is positioned in the gap 16. The second wall portion 12 extends in a second direction (e.g., the Z direction) that intersects with the connection surface 111 and in a direction from the connection surface 111 toward the outside of the housing 10.

[0014] 1, the housing 10 is configured to be attachable to an external device (not shown) such as a control panel via an attachment portion 13 disposed on the opposite side of the connection surface 111 in the second direction Z. A plurality of wiring connection portions 14 are provided on both sides of the first wall portion 11 of the housing 10 in the first direction X. External wiring (not shown) is connected to each wiring connection portion 14.

[0015] As an example, the electronic device 50 has a substantially rectangular parallelepiped shape and has a bottom 51 and a side 52. The bottom 51 faces the connection surface 111 when the electronic device 50 is connected to the connection surface 111. The side 52 extends in the second direction Z and faces the operating portion 21 of the lever 20 in the first direction X when the electronic device 50 is connected to the connection surface 111. The protrusion 53 is provided at the middle of the side 52 of the electronic device 50 in the second direction Z. The bottom 51 of the electronic device 50 is provided with a terminal 54 that extends from the bottom 51 in the second direction Z and is housed inside the housing 10. The terminal 54 is connected to a terminal connection portion 17 provided inside the housing 10. As an example, the terminal connection portion 17 is formed of a pair of leaf springs that can clamp the terminal 54 from the first direction X.

[0016] The lever 20 is attached to the housing 10 in a state where it can rotate about a rotation axis L1 that extends along the connection surface 111. In this embodiment, as shown in Fig. 5, the lever 20 has a generally L-shape as a whole, and includes an operating portion 21 and a contact portion 22. The rotation axis L1 is located at an end 212 of the operating portion 21 that is located inside the housing 10 (in other words, of both ends of the operating portion 21 in the direction in which the operating portion 21 extends, the end 212 that is closer to the connection surface 111).

[0017] 5, for example, the operating unit 21 has a rod shape extending from the rotation axis L1 in a radial direction relative to the rotation axis L1 (hereinafter referred to as the radial direction). As shown in FIG. 1, of both ends of the operating unit 21 in the direction in which the operating unit 21 extends, an end 211 farther from the rotation axis L1 is located outside the housing 10.

[0018] In the present embodiment, the operation unit 21 has a first recess 213 (see FIG. 6) and a second recess 214 (see FIG. 6) that open in a width direction (e.g., the Y direction) that intersects the circumferential direction and the radial direction, a third recess 215 (see FIG. 6) that opens facing the restricting member 30 in the circumferential direction, and a fourth recess 216 (see FIG. 5) that opens facing the electronic device 50 in the circumferential direction. As an example, the operation unit 21 has a pair of first recesses 213 and a pair of second recesses 214. The pair of first recesses 213 and the pair of second recesses 214 open in opposite directions to each other in the width direction Y.

[0019] Each of the first recesses 213 and each of the second recesses 214 is configured to be able to accommodate and hold a first protrusion 33 of the regulating member 30 (described later) (see FIG. 7). Each of the first recesses 213 is located closer to the rotation axis L1 in the radial direction than each of the second recesses 214. Each of the first recesses 213 is provided at a position corresponding to a regulating position P3 of the regulating member 30 (described later). Each of the second recesses 214 is provided at a position corresponding to a release position P4 of the regulating member 30 (described later). As an example, as shown in FIG. 7, the operating unit 21 has a support wall portion 23 that protrudes in the circumferential direction from a surface facing the regulating member 30 and in a direction approaching the regulating member 30, and extends radially. The support wall portion 23 has groove portions 231 that extend radially on both sides of the support wall portion 23 in the width direction Y. One first recess 213 and one second recess 214 are provided in a bottom surface 232 of each groove portion 231.

[0020] The third recess 215 extends in the radial direction and is configured to be able to accommodate a second protrusion 34 of the restricting member 30, which will be described later (see FIG. 2). As shown in FIG. 7, of both radial ends of the third recess 215, an inclined surface 217 is provided on the end closer to the rotation axis L1 (in other words, the end farther from the support wall 23). The inclined surface 217 inclines in the circumferential direction from the opening of the third recess 215 toward the bottom surface as it moves away from the rotation axis L1 in the radial direction.

[0021] The fourth recess 216 is configured to be able to accommodate the protrusion 53 of the electronic device 50 when the operation unit 21 is located at the first position P1 (see FIG. 2). By accommodating the protrusion 53 of the electronic device 50 in the fourth recess 216, movement of the electronic device 50 in the second direction Z and in a direction away from the connection surface 111 is restricted.

[0022] 5, the contact portion 22 extends radially from an end 212 of the operating unit 21 that is closer to the rotation axis L1, in a direction intersecting the extension direction of the operating unit 21. The contact portion 22 is configured to be rotatable around the rotation axis L1 together with the operating unit 21.

[0023] The lever 20 is configured to be rotatable around a rotation axis L1 between a first position P1 and a second position P2. As shown in FIG. 2, the first position P1 is a position where the operating unit 21 is adjacent to the electronic device 50 connected to the connection surface 111 in a circumferential direction about the rotation axis L1 (hereinafter referred to as the circumferential direction). At the first position P1, movement of the lever 20 in the circumferential direction and toward the electronic device 50 is restricted by a protrusion 15 provided on the housing 10. The protrusion 15 is disposed farther away from the connection surface 111 in the circumferential direction than the contact portion 22. The contact portion 22 is configured to be able to come into contact with the protrusion 15 at the first position P1. As shown in FIG. 4, the second position P2 is a position where the operating unit 21 is farther away from the side portion 52 of the electronic device 50 connected to the connection surface 111 in the circumferential direction than the first position P1 and is adjacent to the second wall portion 12 of the housing 10. The operating portion 21 is configured so that the bottom surface of the third recess 215 can come into contact with the second wall portion 12 of the housing 10 when the lever 20 is in the second position P2. That is, the rotation range of the lever 20 is restricted by the housing 10.

[0024] As shown in FIG. 2, when the lever 20 is located at the first position P1, the contact portion 22 is located inside the housing 10 with a tip portion 221, which is the end portion farthest from the operation portion 21 in the first direction X, facing the connection surface 111 in the circumferential direction. As shown in FIG. 4, when the lever 20 is located at the second position P2, the contact portion 22 is located outside the housing 10 with the tip portion 221 facing the connection surface 111 in the circumferential direction. In other words, when the lever 20 is rotated from the first position P1 to the second position P2 with the electronic device 50 connected to the connection surface 111, the contact portion 22 presses the bottom portion 51 of the electronic device 50, moving the electronic device 50 in the second direction Z and in a direction away from the connection surface 111. As a result, the electronic device 50 is disconnected from the socket 1.

[0025] The restricting member 30 is attached to the operating unit 21, for example, in a state in which it is movable in the radial direction between a restricting position P3 and a release position P4. As shown in Fig. 2, the restricting position P3 is a position that is located between the operating unit 21 and the second wall portion 12 in the circumferential direction when the lever 20 is located at the first position P1, and restricts the rotation of the lever 20. As shown in Figs. 3 and 4, the release position P4 is a position that is farther from the rotation axis L1 in the radial direction than the restricting position P3, and where the restriction on the rotation of the lever 20 is released.

[0026] 7, the restricting member 30 has a main body 31, a knob 32, a first protrusion 33, and a second protrusion 34, which are provided on the main body 31. As an example, the restricting member 30 has a pair of the first protrusions 33 and a pair of the second protrusions 34.

[0027] 7, the main body 31 has a generally rectangular plate shape with the radial direction as the longitudinal direction, and has a pair of wall portions 311 extending from the end closer to the rotation axis L1 to approximately the center. The wall portions 311 are positioned with a gap 312 between them in the width direction Y.

[0028] 2, the knob 32 is located at one of the radial ends of the main body 31 that is farther from the rotation axis L1. As an example, the knob 32 has a generally rectangular thin plate shape (see FIG. 7), and when viewed along the width direction Y, it extends in the circumferential direction away from the main body 31 and in the radial direction away from the rotation axis L1.

[0029] As shown in Fig. 7, the pair of first protrusions 33 are located approximately in the radial center of the main body 31. Specifically, the pair of first protrusions 33 are located at the ends of each wall 311 in the radial direction that are farther from the rotation axis L1, and protrude toward each other in the width direction Y. Each first protrusion 33 has a curved tip. In this embodiment, the pair of first protrusions 33, together with the first recess 213 and the second recess 214 of the operation unit 21, constitute a holding mechanism 40 that holds the restricting member 30 at the restricting position P3 and the release position P4.

[0030] 2, the pair of second protrusions 34 are located at the ends closer to the rotation axis L1 of both radial ends of the main body 31. Each second protrusion 34 protrudes from the main body 31 in the circumferential direction toward the operating unit 21.

[0031] Socket 1 can provide the following benefits:

[0032] The socket 1 includes a housing 10, a lever 20, and a restricting member 30. The housing 10 has a first wall 11 having a connection surface 111 to which an electronic device 50 is connected, and a second wall 12 positioned with a gap 16 from the first wall 11 in a first direction along the connection surface 111 and extending in a second direction intersecting the connection surface 111. The lever 20 is positioned in the gap 16 and attached to the housing 10 in a rotatable state about a rotation axis L1 extending along the connection surface 111, and is configured to be able to disconnect the electronic device 50 by rotating the lever 20 about the rotation axis L1. The restricting member 30 is configured to be able to restrict the rotation of the lever 20. The lever 20 has an operating portion 21 extending radially from the rotation axis L1. The lever 20 is configured to be rotatable about the rotation axis L1 between a first position P1 where the operating unit 21 is adjacent to the electronic device 50 connected to the connection surface 111 in the circumferential direction about the rotation axis L1, and a second position P2 where the operating unit 21 is located further away from the electronic device 50 connected to the connection surface 111 in the circumferential direction than the first position P1 and adjacent to the second wall portion 12. The restricting member 30 is attached to the operating unit 21 in a state movable radially between a restricting position P3 where the restricting member 30 is located between the operating unit 21 and the second wall portion 12 in the circumferential direction and restricts the rotation of the lever 20 when the lever 20 is located at the first position P1, and a releasing position P4 where the restricting member 30 is located further away from the rotation axis L1 than the restricting position P3 and releases the restriction on the rotation of the lever 20. With this configuration, when the lever 20 is located at the first position P1, the rotation of the lever 20 can be restricted by positioning the restricting member 30 at the restricting position P3. As a result, it is possible to realize a socket 1 that can prevent the connected electronic device 50 from falling off due to rotation of the lever 20.

[0033] Socket 1 includes a holding mechanism 40 that holds restricting member 30 at restricting position P3 and release position P4. This configuration makes it possible to realize socket 1 that can more reliably prevent connected electronic device 50 from falling off.

[0034] The holding mechanism 40 includes a first protrusion 33 that is provided on the restricting member 30 and protrudes in the width direction from the restricting member 30, a first recess 213 that is provided on the lever 20 and can hold the first protrusion 33 at the restricting position P3, and a second recess 214 that is provided on the lever 20 and can hold the first protrusion 33 at the release position P4. With this configuration, it is possible to realize a socket 1 that can prevent the connected electronic device 50 from falling off with a simple configuration.

[0035] The restricting member 30 is provided at one of its radial ends farther from the rotation axis L1 and has a pinchable knob 32. With this configuration, the restricting position P3 can be easily moved from the restricting position P3 to the release position P4, or from the release position P4 to the restricting position P3.

[0036] The restricting member 30 has a main body 31 and a second protruding portion 34 that protrudes from the main body 31 in the circumferential direction toward the operating portion 21. The operating portion 21 has a third recess 215 that extends radially and opens facing the restricting member 30 in the circumferential direction, and that houses the second protruding portion 34. The operating portion 21 is configured so that the bottom surface of the third recess 215 can come into contact with the second wall portion 12 at the second position P2. With this configuration, the movement range of the restricting member 30 can be restricted while the rotation range of the lever 20 can be widened.

[0037] Socket 1 can also be configured as follows:

[0038] The restricting member 30 may be attached to the housing 10. For example, as shown in FIG. 8, the restricting member 30 may be attached to the second wall portion 12 of the housing 10. In FIG. 8, the restricting member 30 has, as an example, a substantially triangular shape when viewed in the width direction Y (i.e., the direction penetrating the paper surface of FIG. 8). The restricting member 30 is configured to be rotatable between a restricting position P3 and a release position P4 around a rotation axis L2 that passes through one of the vertices of the substantially triangular shape and extends in the width direction Y. The rotation axis L2 is located at a tip 121 of the second wall portion 12 that faces the operating portion 21. The shape of the restricting member 30 can be changed depending on the configuration and shape of the lever 20, etc.

[0039] The restricting member 30 may have any configuration that allows it to be attached to the operating portion 21 in a state in which it can move radially between the restricting position P3 and the release position P4 when the lever 20 is located at the first position P1. For example, the number of each of the first protrusion 33 and the second protrusion 34 is not limited to two, and it may be one, or three or more. Also, at least one of the knob portion 32 and the second protrusion 34 may be omitted.

[0040] The retention mechanism 40 may be omitted.

[0041] The holding mechanism 40 may be configured to hold the restricting member 30 at least in either the restricting position P3 or the release position P4. For example, the holding mechanism 40 may include other components that can hold the restricting member 30 at least in either the restricting position P3 or the release position P4, in addition to or instead of the first protrusion 33, the second protrusion 34, the first recess 213, and the second recess 214. The operating unit 21 may be configured to have only one of the first recess 213 and the second recess 214, or may be configured to have one or three or more first recesses 213 and second recesses 214.

[0042] The number of each of the first recess 213 and the second recess 214 is not limited to two, but may be one, or three or more.

[0043] The present disclosure is not limited to the socket 1, but can be applied to sockets having the following configuration. The socket includes a housing having a connection surface to which an electronic device is connected and a wall portion spaced apart from the connection surface in a first direction along the connection surface and extending in a second direction intersecting the connection surface. The socket is attached to the housing in a state in which it can rotate around a rotation axis that extends along the connection surface between the connection surface and the wall portion, and is provided with a lever that can be rotated around the rotation axis to disconnect the electronic device. The lever has an operating portion extending from the rotation axis in a radial direction relative to the rotation axis. The lever is configured to be rotatable around the rotation axis between a first position where the operating unit is adjacent to the electronic device in the circumferential direction relative to the rotation axis, and a second position where the operating unit is located farther away from the electronic device in the circumferential direction than the first position and adjacent to the wall portion.
