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. The accompanying drawings are schematic, and the proportions of the dimensions and the like do not necessarily correspond to reality.

[0010] As shown in FIGS. 1 and 2, the socket 1 of the present disclosure includes an insulating housing 10 having a receiving portion 11 provided therein, and a terminal 20 and a leaf spring 30 positioned in the receiving portion 11.

[0011] In this embodiment, as shown in FIG. 1, the housing 10 has a thin plate shape, a connection surface 12 and a plurality of wiring connection portions 2 arranged side by side in a first direction (e.g., the X direction), and an attachment portion 13 located on the opposite side of the connection surface 12 in a second direction (e.g., the Z direction) intersecting the first direction X.

[0012] 1, the connection surface 12 is configured to allow connection of electronic devices including an electromagnetic relay. A plurality of wiring connection portions 2 are located on both sides of the connection surface 12 in the first direction X. The mounting portion 13 is configured to allow the housing 10 to be mounted to an external device (not shown) such as a control panel.

[0013] 2, each wiring connection portion 2 includes an accommodation portion 11, a first hole portion 14, a second hole portion 15, and a terminal 20 and a leaf spring 30 accommodated in the accommodation portion 11. The first hole portion 14 and the second hole portion 15 are positioned side by side in the first direction X, and connect the outside of the housing 10 to the accommodation portion 11, respectively.

[0014] The storage section 11 has, for example, a pair of side surfaces 111 and a bottom surface 112. The pair of side surfaces 111 each extend in the same direction as the first hole portion 14 and face each other in the first direction X. The bottom surface 112 faces the first hole portion 14 and the second hole portion 15 in the second direction Z.

[0015] 2, the housing 10 includes a protrusion 16 that is located in the accommodating portion 11 of each wiring connection portion 2 and that protrudes in a third direction (e.g., the Y direction) that intersects the first direction X and the second direction Z. The protrusion 16 has an inclined surface 17 that faces the second hole 15 in the second direction Z. The inclined surface 17 is inclined so as to approach the first hole 14 in the first direction X as it moves toward the inside of the housing 10 in the second direction Z.

[0016] For example, the first hole 14 and the second hole 15 each extend along the second direction Z. The first hole 14 is configured so that a conductor portion 100 of an electric wire can be inserted therein. The conductor portion 100 of the electric wire is housed in the housing portion 11 through the first hole 14. The second hole 15 is configured so that a rod-shaped jig 200 such as a flathead screwdriver can be inserted therein. The jig 200 is housed in the housing portion 11 through the second hole 15.

[0017] As an example, the terminal 20 has a generally C-shaped plate shape extending along a pair of side surfaces 111 and a bottom surface 112. A first portion 21 extending along the side surface 111 near the first hole portion 14 of the terminal 20 is configured to be able to come into contact with a conductor portion 100 of the electric wire accommodated in the accommodating portion 11.

[0018] As an example, the leaf spring 30 includes a first linear portion 31 having a substantially straight plate shape, a curved portion 32 having a curved plate shape, and a second linear portion 33 having a substantially straight plate shape, and has a substantially V-shape overall. The first linear portion 31 is attached to a second portion 22 extending along a side surface 111 close to the second hole 15 of the terminal 20. The curved portion 32 connects the ends of the first linear portion 31 and the second linear portion 33 far from the bottom surface 112 of the accommodating portion 11. The second linear portion 33 is configured to be movable relative to the first linear portion 31 between a return position P1 and an operating position P2. The return position P1 is a position where the tip of the second linear portion 33 contacts the first portion 21 of the terminal 20. The operating position P2 is a position where the second linear portion 33 contacts the inclined surface 17 of the housing 10. In the operating position P2, the second linear portion 33 is biased toward the return position P1.

[0019] When the conductor portion 100 of the electric wire is inserted into the accommodating portion 11 through the first hole portion 14, the second straight portion 33 is pressed by the conductor portion 100 of the electric wire and moves from the return position P1 toward the operating position P2. When the conductor portion 100 of the electric wire is accommodated in the accommodating portion 11, the conductor portion 100 of the electric wire is positioned between the first portion 21 of the terminal 20 and the second straight portion 33 of the leaf spring 30. In this state, the return force of the second straight portion 33 toward the return position P1 holds the conductor portion 100 of the electric wire in contact with the first portion 21 of the terminal 20. In other words, the leaf spring 30 is configured to be able to hold the conductor portion 100 in contact with the terminal 20.

[0020] When the jig 200 is inserted into the accommodating portion 11 through the second hole 15 while the conductor portion 100 of the electric wire is held in contact with the terminal 20, the second straight portion 33 is pressed by the jig 200 and moves to the operating position P2. This releases the state in which the conductor portion 100 of the electric wire is in contact with the terminal 20. In other words, the leaf spring 30 is configured so that the rod-shaped jig 200, which is housed in the accommodating portion 11 through the second hole 15, can release the state in which the conductor portion 100 of the electric wire is in contact with the terminal 20.

[0021] 3, the housing 10 has a dispersion portion 40 that distributes stress generated in the housing 10 due to contact with the jig 200. The dispersion portion 40 is located in a portion of the housing 10 where stress is likely to be generated due to contact with the jig 200, for example, when the jig 200 is used to release the contact state in which the conductor portion 100 of the electric wire is in contact with the terminal 20. In this embodiment, the dispersion portion 40 is provided in a first housing portion 51 of the housing 10. The first housing portion 51 is located between the first hole portion 14 and the second hole portion 15 in the first direction X and extends in the second direction Z.

[0022] The first housing portion 51 has a first portion 511 that is located at one of both ends in the second direction Z that is closer to the accommodation portion 11 and is configured to be able to come into contact with the jig 200 accommodated in the accommodation portion 11. The dispersion portion 40 is located in the first portion 511 and includes a recess 41 that extends from one end of the first housing portion 51 to the other end in the third direction Y. As an example, the recess 41 has an opening with a curved edge. The recess 41 may have a bottom, or may penetrate the first housing exterior 51 in the third direction Y.

[0023] In this embodiment, as shown in FIG. 3, the socket 1 is configured as follows. The housing 10 has an opening edge 54 that forms the end of the second hole 15 connected to the outside of the housing 10. The opening edge 54 is configured to be able to come into contact with the first intermediate portion 201 of the jig 200 housed in the housing portion 11. The leaf spring 30 is configured so as to be able to come into contact with the tip end 202 of the jig 200 housed in the housing portion 11 from the same direction as the opening edge portion 54 of the housing 10 . The first part 511 of the first housing part 51 is configured to be able to contact the second intermediate part 203 located between the first intermediate part 201 and the tip part 202 of the jig 200 accommodated in the accommodation part 11 from the opposite direction to the opening edge part 54 of the housing 10 and the leaf spring 30. The jig 200 accommodated in the accommodation portion 11 can be clamped between the opening edge portion 54 of the housing 10 and the leaf spring 30 and the first portion 511 of the first housing portion 51 .

[0024] For example, when the jig 200 is accommodated in the accommodation portion 11 through the second hole portion 15, if an external force is applied to the jig 200 in a direction (for example, direction A shown in FIG. 3) that intersects with the direction in which the jig 200 is inserted into the second hole portion 15, stress is generated in the housing 10 via the first housing portion 51. The generated stress is dispersed by the dispersion portion 40 located in the first portion 511 of the first housing portion 51, preventing deformation of the housing 10.

[0025] Socket 1 can provide the following benefits:

[0026] The socket 1 includes a housing 10, a terminal 20, and a leaf spring 30. The housing 10 has an accommodating section 11 provided therein, and a first hole 14 and a second hole 15 positioned side by side in a first direction and connecting the outside of the housing 10 to the accommodating section 11, respectively. The terminal 20 is located in the accommodating section 11 and configured to be able to contact a conductor portion 100 of an electric wire accommodated in the accommodating section 11 via the first hole 14. The leaf spring 30 is located in the accommodating section 11 and configured to be able to hold the conductor portion 100 of the electric wire in contact with the terminal 20, and to be able to release the contact state via the second hole 15 by a rod-shaped jig 200 accommodated in the accommodating section 11. The housing 10 has a dispersing section 40 located in a portion where stress is likely to be generated by contact with the jig 200, and disperses stress generated in the housing 10 due to contact with the jig 200. With this configuration, it is possible to realize a socket 1 that can prevent deformation of the housing 10 due to stress generated by contact with the jig 200.

[0027] The dispersion portion 40 is provided in the first housing portion 51 of the housing 10. With this configuration, the dispersion portion 40 can be positioned around the portion of the housing 10 that comes into contact with the jig 200. As a result, a socket 1 can be realized that can more reliably prevent deformation of the housing 10 due to stress generated by contact with the jig 200.

[0028] The first housing portion 51 has a first portion 511 located at one of both ends in the second direction that is closest to the accommodation portion 11 and configured to be able to come into contact with the jig 200 accommodated in the accommodation portion 11. The dispersion portion 40 is located in the first portion 511 of the first housing portion 51 and includes a recess 41 extending from one end of the first housing portion 51 to the other end in the third direction. With this configuration, the dispersion portion 40 can be positioned near the portion of the housing 10 that comes into contact with the jig 200. As a result, a socket 1 can be realized that can more reliably prevent deformation of the housing 10 due to stress generated by contact with the jig 200.

[0029] The housing has an opening edge portion 54 that forms an end portion of the second hole portion 15 connected to the outside of the housing 10. The opening edge portion 54 is configured to be able to come into contact with a first intermediate portion 201 of the jig 200 housed in the accommodating portion 11. The leaf spring 30 is configured to be able to come into contact with a tip portion 202 of the jig 200 housed in the accommodating portion 11 from the same direction as the opening edge portion 54. The first portion 511 of the first housing portion 51 is configured to be able to come into contact with a second intermediate portion 203 located between the first intermediate portion 201 and the tip portion 202 of the jig 200 housed in the accommodating portion 11 from the opposite direction to the opening edge portion 54 and the leaf spring 30. The opening edge portion 54, the leaf spring 30, and the first portion 511 of the first housing portion 51 can clamp the jig 200 housed in the accommodating portion 11. With this configuration, the jig 200 housed in the accommodating portion 11 can be held in a hands-free state without supporting it with a hand or the like.

[0030] Socket 1 can be configured as follows:

[0031] The dispersion portion 40 is not limited to being provided in the first portion 511 of the first housing portion 51, and can be configured, for example, as shown in Figures 4 to 6. With such a configuration, it is possible to realize a socket 1 that can more reliably prevent deformation of the housing 10 due to stress generated by contact with the jig 200.

[0032] In FIG. 4, the dispersion portion 40 is provided in the second portion 512 of the first housing portion 51 that constitutes part of the inner surface of the first hole portion 14. The dispersion portion 40 in FIG. 4 has two first notches 42 located at the ends of the second portion 512 in the second direction Z that are closer to the accommodating portion 11. The two first notches 42 are located spaced apart in the third direction Y. Each first notch 42 extends from the first hole portion 14 toward the second hole portion 15 along the first direction X. The dispersion portion 40 may have one first notch 42, or may have three or more first notches 42.

[0033] In FIG. 5 , the dispersion portion 40 is provided in the second housing portion 52. The second housing portion 52 extends in the first direction X from one of both ends of the first housing portion 51 in the second direction Z that is closest to the accommodating portion 11 (i.e., the first portion 511) in the first direction X and in a direction away from the second hole portion. The second housing portion 52 is provided with a first opening 141 connected to the accommodating portion 11 of the first hole portion 14. The dispersion portion 40 in FIG. 5 has two second notches 43 provided on the edge of the first opening 141 of the second housing portion 52. As an example, each second notch 43 extends from the accommodating portion 11 toward the outside of the housing 10 along the second direction Z. In FIG. 5 , one second notch 43 (the second notch 43 closest to the accommodating portion 11 in the third direction Y in FIG. 5 ) penetrates the second housing portion 52 in the third direction Y to connect the first hole portion 14 to the outside of the housing 10. The dispersion portion 40 may have one second notch 43 or may have three or more second notches 43.

[0034] In FIG. 6 , the dispersion portion 40 is provided in the third housing portion 53. The third housing portion 53 extends from the first housing portion 51 in the first direction X and in a direction away from the first hole portion 14. The third housing portion 53 is provided with a second opening 151 connected to the outside of the housing 10 at the second hole portion 15. The dispersion portion 40 in FIG. 6 has a third notch 44 provided on the edge of the second opening 151 of the third housing portion 53. The third notch 44 is configured to be able to come into contact with the jig 200 accommodated in the accommodation portion 11. As an example, the second opening 151 has a substantially rectangular shape when viewed along the second direction Z. The third notch 44 is located approximately in the center in the third direction Y of the edge of the second opening 151 facing the first direction X, far from the first hole portion 14, and constitutes an opening edge portion 54 of the housing 10. The third notch 44 has a curved concave shape recessed from the inner surface of the second hole portion 15 in the first direction X and in a direction away from the first hole portion 14. The bottom surface of the third notch 44 is inclined so as to approach the first hole portion 14 in the first direction X as it moves from the outside of the housing 10 toward the accommodating portion 11 in the second direction Z.

[0035] The dispersion portion 40 is not limited to any one of the recess 41, the first notch 42, the second notch 43 and the third notch 44, but may include any or all of the recess 41, the first notch 42, the second notch 43 and the third notch 44.

[0036] The housing 10 is not limited to having a plurality of wiring connection portions 2, but may have at least one wiring connection portion 2.

[0037] The socket 1 is not limited to the case where the jig 200 accommodated in the accommodating portion 11 can be clamped between the opening edge portion 54, the leaf spring 30, and the first portion 511 of the first housing portion 51. In other words, the socket 1 does not have to be able to hold the jig 200 accommodated in the accommodating portion 11 in a hands-free state without supporting it with a hand or the like.
