Description

Cord stopper

[0001] The present invention relates to a cord stopper that holds a cord by inserting a plug into a socket through which the cord is inserted.

[0002] A cord stopper is known in the art that, when a plug is inserted into a socket with a string inserted therethrough, presses the string against the inner surface of the socket to hold the string (see Patent Document 1). The socket has a pair of surface portions that form an insertion opening, and one of the pair of surface portions has a tape attachment portion that stands upright relative to the other surface portion. The tape attachment portion is spaced apart from the socket insertion opening in the thickness direction of the surface portion, and a tape member fixed near a string hole or the like in the opening of a bag or the like is wound around the tape attachment portion. The plug also has a pair of operating portions that are located outward and parallel to the pair of surface portions of the socket. With this cord stopper, the operating portions can be held with one hand and pulled to widen the gap between the plug and socket, thereby changing the string from a held state to a slidable state.

[0003] International Publication No. 2023 / 017566

[0004] Incidentally, in the cord stopper described in Patent Document 1, the tape attachment portion is positioned away from the socket insertion opening in the thickness direction of the surface portion, but since the pair of operating portions of the plug mentioned above are held and pulled with one hand, the orientation of the cord stopper can be stabilized even if a rotational moment is generated in the cord stopper when the plug is pulled away from the socket, and the cord stopper can be operated smoothly.

[0005] However, for example, if a tape attachment portion is provided on the plug instead of the pair of operating portions described above, when the plug is pulled away from the socket by pulling the tape wrapped around the tape attachment portion of the plug, a rotational moment will be generated in the cord stopper depending on the relative positions of the tape attachment portion of the socket and the tape attachment portion of the plug.Furthermore, since the cord stopper itself cannot be held with the fingers or the like at this time, the orientation of the cord stopper will become unstable, and it may become difficult to operate the cord stopper smoothly.

[0006] An object of the present invention is to provide a cord stopper that can improve the operability of separating a plug and a socket.

[0007] [1] A cord stopper according to one aspect of the present invention comprises a socket having a socket main body portion with a front surface portion and a back surface portion and having an insertion opening formed therethrough, and a socket side connecting rod continuous with the socket main body portion; a plug having a plug main body portion that is inserted into the insertion opening movably in the insertion direction into the socket and that holds a string between itself and the socket main body portion, and a plug side connecting rod continuous with the plug main body portion, wherein the socket side connecting rod and the plug side connecting rod are positioned on the back side of the insertion opening in the front-back direction perpendicular to the insertion direction.

[0008] [2] In this aspect, the plug-side connecting rod may be located on the front side of the socket-side connecting rod and below the cord.

[0009] [3] In this aspect, two of the strings are inserted into the socket, the plug is disposed between the two strings in a width direction perpendicular to the insertion direction, and the plug-side connecting rod is formed to extend in the width direction from the plug main body and may have an inclined surface that slopes backward relative to the width direction as it extends outward in the width direction.

[0010] [4] In this aspect, a front guide groove extending along the insertion direction is formed on the inner surface of the front portion, a back guide groove extending along the insertion direction is formed on the inner surface of the back portion, the plug body has guided portions of corresponding shapes so as to be guided by the front guide groove and the back guide groove, respectively, and the width dimensions of the front guide groove and the back guide groove may be different from each other in a width direction perpendicular to the insertion direction.

[0011] [5] In this aspect, the length dimension of the front surface portion in the insertion direction may be greater than the length dimension of the back surface portion in the insertion direction.

[0012] [6] In this aspect, the surface portion may be formed so that the width dimension in a width direction perpendicular to the insertion direction increases toward the insertion side of the plug in the insertion direction.

[0013] [7] In this aspect, the surface portion may be formed with a protrusion that protrudes toward the front side at a position opposite to the insertion side of the plug in the insertion direction.

[0014] [8] In this aspect, the socket has a side portion continuous with the front and back portions, and the end of the side portion on the insertion side of the plug may constitute the bottom surface of a recess formed in cooperation with the front and back portions.

[0015] According to the present invention, it is possible to provide a cord stopper that can improve the operability of separating a plug and a socket.

[0017] [Configuration of the Present Embodiment] An embodiment of the present invention will now be described with reference to the drawings. Referring to Figs. 1 to 5, a cord stopper 1 according to this embodiment can be fastened to a cord 2 along the opening of an article such as a backpack at any desired position. By adjusting the fastening position relative to the cord 2, the opening of the article can be tightened to close or loosened to open. The cord stopper 1 includes a socket 11 and a plug 12 inserted into the socket 11. The socket 11 has a socket body 20 formed with an insertion opening 10 therethrough and a socket-side connecting rod 30 continuous with the socket body 20. A strip-shaped tape 3 serving as a connectable member, the end of which is fixed to an article such as a backpack, is wound around and attached to the socket-side connecting rod 30. The plug 12 has a plug body 40 that sandwiches the cord 2 between itself and the socket body 20, and a plug-side connecting rod 50 that is continuous with the plug body 40. A strip-shaped tape 4 is wound around the plug-side connecting rod 50 as a connected object. The end of the tape 4 may also be fixed to an article. In the following description, for convenience, the front-to-rear direction of the cord stopper 1 (the direction in which the plug 12 is inserted into the socket 11) is defined as the X-axis direction, the width direction (left-to-right direction) of the cord stopper 1 is defined as the Y-axis direction, and the front-to-back direction (thickness direction) of the cord stopper 1 is defined as the Z-axis direction. The X-, Y-, and Z-axes are perpendicular to one another. Note that FIGS. 3 and 5 show an inserted state in which the plug 12 is deeply inserted into the socket 11 and a removed state in which the plug 12 is pulled away from the socket 11 in the X-axis direction. Figure 4 shows a perspective view of the cord stopper 1 seen from the front side and a perspective view of the cord stopper 1 seen from the back side, with the plug 12 in the unplugged state shown in solid lines and the plug 12 in the plugged state shown in dashed double-dashed lines.

[0018] [Socket] The socket 11 is shown as a single unit in FIGS. 6 and 7, and is made of synthetic resin and is integrally molded.

[0019] The socket main body 20 has a front surface portion 21 and a back surface portion 22 that face each other in the Z-axis direction, and a pair of side surface portions 23 that are continuous with both side edges of the front surface portion 21 and the back surface portion 22 and face each other in the Y-axis direction.

[0020] The front surface portion 21 is formed flat along the X and Y axes. The length of the front surface portion 21 in the X axis direction is greater than the length of the back surface portion 22 in the X axis direction, and extends rearward (toward the insertion side of the plug 12) from the back surface portion 22 in the X axis direction. The front surface portion 21 is also formed so that its width in the Y axis direction gradually increases from the front side (opposite the insertion side of the plug 12) to the rear side in the X axis direction.

[0021] A trapezoidal protrusion 211 is formed on the surface portion 21 at a position on the front side in the X-axis direction from the outer surface 21A of the surface portion 21 to the front side in the Z-axis direction. The protrusion 211 is formed along the front end of the surface portion 21.

[0022] 5 and 7, a front guide groove 212 in the form of a stripe extending along the X-axis direction is formed on the inner surface 21B of the surface portion 21. A front abutment portion 213 is formed in the front guide groove 212 and abuts against a front guided portion 411 (described later) of the plug 12 in the X-axis direction. The front abutment portion 213 is abutted by the front guided portion 411, thereby restricting rearward movement of the plug 12 beyond a predetermined position.

[0023] The back surface portion 22 is formed flat along the X and Y axes. The back surface portion 22 is formed so that its width in the Y axis direction gradually increases from the front side to the rear side in the X axis direction. The back surface portion 22 is formed so that left and right portions 224 in the Y axis direction at its rear end are positioned forward of a central portion 225 of the end, and an inclined surface 226 is formed between the left and right portions 224 and the central portion 225, connecting them. The socket-side connecting rod 30 is continuous with the front end of the back surface portion 22.

[0024] Furthermore, a back-side guide groove 222 having a groove shape extending along the X-axis direction is formed on the inner surface 22B of the back surface portion 22. A back-side abutment portion 223 that engages with the back-side guided portion 421 of the plug 12 in the X-axis direction is formed in the back-side guide groove 222, and the back-side guided portion 421 abuts against this back-side abutment portion 223, thereby restricting movement of the plug 12 rearward beyond a predetermined position. Here, the width dimension W1 in the Y-axis direction of the front-side guide groove 212 and the width dimension W2 in the Y-axis direction of the back-side guide groove 222 are different dimensions, and in this embodiment, the relationship W1<W2 is satisfied. Furthermore, the front guided portion 411 of the plug 12 has a width dimension corresponding to the width dimension W1 of the front guide groove 212, and the back guided portion 421 has a width dimension corresponding to the width dimension W2 of the back guide groove 222. Therefore, even if an attempt is made to insert the plug 12 upside down into the socket 11, the back guided portion 421 of the plug 12 will hit the socket 11, and the plug 12 cannot be inserted into the socket 11 upside down.

[0025] Each of the side surface portions 23 is formed in a plate shape along the X- and Z-axis directions. The length of the side surface portion 23 in the X-axis direction is smaller than the length of the back surface portion 22. The rear end of the side surface portion 23 cooperates with the inner surfaces 21B, 22B of the front surface portion 21 and the back surface portion 22 to form a recess 24 that is recessed toward the front side of the socket 11. The rear end of the side surface portion 23 forms the bottom surface of the recess 24, and the inner surfaces 21B, 22B form a pair of side surfaces of the recess 24.

[0026] The socket 11 described above is formed into a substantially rectangular tube shape by a front surface portion 21, a back surface portion 22, and a pair of side surface portions 23, and defines an insertion opening 10 penetrating in the X-axis direction. Two strings 2 are inserted through the insertion opening 10. When the front contact portion 213 and the back contact portion 223 described above are present, applying a large force in the X-axis direction to the plug 12 and inserting it into the socket 11 causes elastic deformation of the socket 11 itself, causing the front guided portion 411 of the plug 12 to overcome the front contact portion 213 and the back guided portion 421 to overcome the back contact portion 223, thereby assembling the socket 11 and the plug 12. The plug 12 can move a predetermined amount in the X-axis direction relative to the socket 11. Note that a state in which the plug 12 is deeply inserted into the socket 11 in the X-axis direction is referred to as an inserted state, and a state in which the plug 12 is pulled away from the socket 11 in the X-axis direction is referred to as a pulled state.

[0027] The socket-side connecting rod 30 is U-shaped and has a pair of side portions 31 facing each other in the Y-axis direction and a rectangular rod-like connecting portion 32 that is continuous with the pair of side portions 31 and extends in the Y-axis direction, and the tape 3 is wound around and connected to the connecting portion 32. The socket-side connecting rod 30 has the pair of side portions 31 that protrude rearward in the Z-axis direction from the front end of the back surface 22 in the X-axis direction (the end opposite the plug 12), and the connecting portion 32 is disposed spaced apart in the Z-axis direction from the outer surface 22A of the back surface 22. The socket-side connecting rod 30 cooperates with the back surface 22 to form a connecting hole 35 through which the tape 3 is passed.

[0028] [Plug] The plug 12 is shown as a single unit in Figs. 8 and 9, and is made of synthetic resin and is integrally molded.

[0029] The plug body 40 is formed to extend in the X-axis direction and has a front surface 41, a back surface 42, a pair of side surfaces 43, a front surface 44, and a rear surface 45. The pair of side surfaces 43 are continuous with both side edges of the front surface 41 and the back surface 42 and are inclined with respect to the X-axis direction so as to move away from each other in the Y-axis direction from the front side to the rear side in the X-axis direction. The front surface 44 is continuous with the front edges of the front surface 41, the back surface 42, and the pair of side surfaces 43 located on the front side in the X-axis direction, and the rear surface 45 is continuous with the rear edges of the front surface 41, the back surface 42, and the pair of side surfaces 43 located on the rear side in the X-axis direction.

[0030] At the front end of the surface 41, a front guided portion 411 (guided portion) is formed which protrudes toward the front side in the Z-axis direction, and at the front end of the back surface 42, a back guided portion 421 (guided portion) is formed which protrudes toward the back side in the Z-axis direction.

[0031] The front-side guided portion 411 is formed in a shape corresponding to the front-side guide groove 212 described above, has a width dimension corresponding to the width dimension W1 of the front-side guide groove 212, and is guided in the X-axis direction by the front-side guide groove 212. The front-side guided portion 411 also has an inclined surface 412 that inclines toward the back surface 42 as it moves forward, so that when the plug 12 separated from the socket 11 is assembled into the socket 11, the inclined surface 412 slides against the front-side abutment portion 213, allowing the front-side guided portion 411 to easily ride over the front-side abutment portion 213 of the socket 11 compared to a case in which the inclined surface 412 is not formed.

[0032] The back-side guided portion 421 is formed in a shape corresponding to the back-side guide groove 222 described above, has a width corresponding to the width dimension W2 of the back-side guide groove 222, and is guided in the X-axis direction by the back-side guide groove 222. The back-side guided portion 421 also has an inclined surface 422 that is inclined toward the front surface 41 as it moves forward, and therefore, by sliding against the inclined surface 422 in a state separated from the socket 11, the front-side guided portion 411 can more easily get over the back-side abutment portion 223 of the socket 11 than if the inclined surface 422 were not formed.

[0033] The pair of side surfaces 43 each constitute a cord holding portion 43A formed with an uneven shape in the X-axis direction, and are disposed opposite the inner surface 23B of the side surface portion 23 of the socket 11 in the Y-axis direction. The cord holding portion 43A holds the cord 2 by clamping it between itself and the inner surface 23B when the plug 12 is inserted into the socket 11. When the plug 12 is pulled out of the socket 11, the cord holding portion 43A releases the clamping, allowing the cord 2 to move in the X-axis direction relative to the cord stopper 1. 23A is the outer surface of the side surface portion 23.

[0034] The plug-side connecting rod 50 has a pair of side portions 51 facing each other in the Y-axis direction, a rectangular rod-shaped connecting portion 52 that is continuous with the pair of side portions 51 and extends in the Y-axis direction, and a connecting portion 53 that connects the front ends of the pair of side portions 51 in the X-axis direction to the rear portions of the pair of side surface portions 23 of the socket body 20, respectively, and has a width dimension equivalent to the width dimension of the socket 11 in the Y-axis direction. The pair of side portions 51 and the connecting portion 52 form a U-shaped portion. The side portions 51 are aligned along the X-axis direction, and the connecting portion 52 is spaced rearward from the plug body 40 and is connected by wrapping tape 4 around it. The pair of side portions 51 and the connecting portion 52 that form the U-shaped portion are located closer to the front of the socket-side connecting rod 30 in the Z-axis direction and lower than the string 2. In the plug-side connecting rod 50, one of the pair of side portions 51 is disposed on the outside of one of the pair of side portions 51 in the Y-axis direction, and the other of the pair of side portions 51 is disposed on the outside of the other of the pair of side portions 51 in the Y-axis direction. Each of the pair of side portions 51 is disposed at a position more outward in the Y-axis direction than the plug body 40, and the connecting hole 46 is formed wider in the Y-axis direction than the plug body 40. The pair of connecting portions 53 are formed to expand in the Y-axis direction from the rear portion of the side surface portion 23 of the plug body 40, and have inclined surfaces 531 that are inclined backward with respect to the Y-axis direction as they extend outward in the Y-axis direction. One of the inclined surfaces 531 in the pair of connecting portions 53 guides one of the two cords 2 inserted through the insertion opening 10 formed in the socket 11 outward in the Y-axis direction, and the other of the inclined surfaces 531 in the pair of connecting portions 53 guides the other of the two cords 2 inserted through the insertion opening formed in the socket 11 outward in the Y-axis direction, so that the two cords 2 are guided by the inclined surfaces 531 and are spaced apart from each other in the Y-axis direction and positioned on the pair of side portions 51. The plug-side connecting rod 50 cooperates with the rear surface 45 of the plug body 40 to form a connecting hole 46 through which the tape 4 is passed.

[0035] When assembling the plug 12 described above to the socket 11, first, the two strings 2 are inserted through the insertion opening 10 of the socket 11, and the plug main body 40 is inserted into the insertion opening 10 of the socket 11 from the front surface 44 while being positioned between the two strings 2. Next, the plug 12 is pressed in the X-axis direction, causing the front-side guided portions 411 and the back-side guided portions 421 to move forward past the front-side abutment portions 213 and the back-side abutment portions 223. This completes the assembly of the plug 12 to the socket 11. At this time, the two strings 2 are positioned in the clamping spaces formed between the inner surfaces 23B of the pair of side surface portions 23 of the socket 11 and the string holding portions 43A on the pair of side surfaces 43 of the plug 12. The plug 12 is able to move a predetermined amount in the X-axis direction within a range in which the front-side guided portion 411 and the back-side guided portion 421 do not move rearward past the front-side abutment portion 213 and the back-side abutment portion 223. When the plug 12 is inserted deeply into the socket 11 in the X-axis direction, the clamping space narrows in the Y-axis direction, so that the two cords 2 are tightly clamped between the inner surface 23B of the socket 11 and the cord holding portion 43A of the plug 12. This fixes the cord stopper 1 to any position on the cords 2, making it possible to tighten and close the opening of an item such as a backpack, or to loosen and open it. Furthermore, in the pulled-out state where the plug 12 is pulled away from the socket 11 in the X-axis direction, the clamping space expands in the Y-axis direction, loosening the clamping of the string 2, which allows the string 2 to slide in the X-axis direction relative to the cord stopper 1. By adjusting the position of the cord stopper 1 relative to the string 2, it is possible to tighten and close the opening of an item such as a backpack, or loosen and open it.

[0036] In the above-described cord stopper 1, both the socket-side connecting rod 30 and the plug-side connecting rod 50 (particularly the U-shaped portion) are positioned on the back side of the insertion opening 10 in the Z-axis direction. Therefore, when, for example, one of the tapes 3, 4 connected to the socket-side connecting rod 30 and the plug-side connecting rod 50, tape 4 in this case, is pulled in the X-axis direction to separate the plug 12 from the socket 11 in the X-axis direction, the rotational moment that may occur in the cord stopper 1 is suppressed, and the orientation of the cord stopper 1 is stabilized. This allows for smooth operation of the cord stopper 1.

[0037] [Modifications] In the above embodiment, the plug-side connecting rod 50 is positioned closer to the front than the socket-side connecting rod 30 and lower relative to the cord 2, but this is not limiting. As long as the rotational moment that may occur in the cord stopper 1 can be suppressed, the plug-side connecting rod 50 may be positioned at the same position in the Z-axis direction as the socket-side connecting rod 30, or may be positioned lower than the socket-side connecting rod 30.

[0038] In the above embodiment, the plug side connecting rod 50 is formed to extend in the Y-axis direction from the plug main body 40 and has an inclined surface 531 that is inclined backward with respect to the Y-axis direction as it moves outward in the Y-axis direction. However, this is not limited to this, and the configuration of the inclined surface 531 described above may be omitted as long as the string body 2 can be wrapped around so that the cord stopper 1 through which the string body 2 is inserted can be operated even without the inclined surface 531.

[0039] In the above embodiment, the front-side guide groove 212 and the back-side guide groove 222 of the socket 11 have a width dimension relationship of W1 < W2, but this is not limited thereto and may be, for example, a relationship of W1 > W2. Furthermore, the front-side guide groove 212 and the back-side guide groove 222 have width dimensions W1, W2 different from each other, but this is not limited thereto and the shapes of the front-side guide groove 212 and the back-side guide groove 222 themselves may be different from each other. In this case, the front-side guided portion 411 and the back-side guided portion 421 of the plug 12 are formed to have width dimensions and shapes corresponding to the front-side guide groove 212 and the back-side guide groove 222.

[0040] In the above embodiment, the length dimension in the X-axis direction of the front surface portion 21 of the socket 11 is formed to be larger than the length dimension in the X-axis direction of the back surface portion 22. However, this is not limited to this. For example, if it is desired to expose the plug 12 on the front side, the length dimension of the front surface portion 21 may be equal to or smaller than the length dimension of the back surface portion 22.

[0041] In the above embodiment, the surface portion 21 of the socket 11 is formed so that the dimension in the Y-axis direction increases as it moves from the front side to the rear side (the side where the plug 12 is inserted) in the X-axis direction, but this is not limited to this, and the width dimension may be the same from the front side to the rear side, or the dimension may decrease as it moves from the front side to the rear side.

[0042] In the above embodiment, the surface portion 21 is formed with a protrusion 211 that protrudes outward from the front side in the X-axis direction (opposite the insertion side of the plug 12), but this is not limited to this. If the socket 11 can be held sufficiently stably when the cord stopper is operated even without the protrusion 211, the configuration of the protrusion 211 may be omitted.

[0043] In the above embodiment, the surface portion 21, the back portion 22 and the side portion 23 form a recess 24 on the rear side of the socket 11, and the end of the side portion 23 forms the bottom surface of the recess 24, but if the string body 2 can be wrapped around the cord stopper 1 in an operable manner without forming the recess 24, the configuration of the recess 24 may be omitted.

[0044] In the above embodiment, the string holding portion 43A is formed on the side surface 43 of the plug 12, but this is not limited thereto. For example, instead of the string holding portion 43A formed on the side surface 43, or in addition to the string holding portion 43A formed on the side surface 43, a string holding portion having an uneven shape may be formed on the inner surface 23B of the side surface portion 23 of the socket 11.

[0045] In the above embodiment, the cord stopper 1 is used as a piece through which a string 2 is inserted along the opening of an item such as a backpack, but it may also be used as a piece through which a string 2 is inserted on other items such as bags, clothing, and cold weather gear.

[0046] [Action and effect] (1) The cord stopper 1 of this embodiment comprises a socket 11 having a socket main body 20 with a front surface 21 and a back surface 22 and through which an insertion opening 10 is formed, and a socket side connecting rod 30 continuous with the socket main body 20, and a plug 12 having a plug main body 40 that is inserted into the insertion opening 10 movably in the insertion direction into the socket 11 (X-axis direction) and holds the cord 2 between itself and the socket main body 20, and a plug side connecting rod 50 continuous with the plug main body 40, and the socket side connecting rod 30 and the plug side connecting rod 50 are positioned on the back side of the insertion opening 10 in the front-to-back direction (Z-axis direction) perpendicular to the insertion direction. According to the cord stopper 1 of this embodiment, the socket side connecting rod 30 and the plug side connecting rod 50 are positioned on the back side of the insertion opening 10 of the socket 11, as described above, and therefore can be positioned so as not to interfere with the string 2 being inserted into the insertion opening 10.Furthermore, compared to, for example, a case where the socket side connecting rod 30 is positioned on the back side and the plug side connecting rod 50 is positioned along the insertion opening 10 in the X-axis direction or on the front side, a rotational moment is less likely to be generated in the cord stopper 1 when either one of the connected objects, such as the strip-shaped tapes 3 and 4 connected to the socket side connecting rod 30 and the plug side connecting rod 50, is pulled to separate the socket 11 and the plug 12 in the X-axis direction, thereby improving operability when separating the plug 12 and the socket 11. Furthermore, since the plug-side connecting rod 50 is positioned on the back side of the insertion port 10 of the socket 11, there is no need to provide an operating part or the like that is positioned on the outside of the surface portion 21 of the socket 11. As a result, the area of ​​the outer surface 21A of the surface portion 21 of the socket main body 20 can be increased, making it easier to apply various logos and the like to the surface portion 21.

[0047] (2) In the cord stopper 1 of this embodiment, the plug-side connecting rod 50 is positioned closer to the front than the socket-side connecting rod 30 and lower relative to the cord 2. With this configuration, the plug-side connecting rod 50 is positioned closer to the plug body 40, which allows the plug 12 itself to be made smaller. Furthermore, by positioning the plug-side connecting rod 50 below the cord 2, the plug-side connecting rod 50 can guide the cord 2 in the X-axis direction.

[0048] (3) In the cord stopper 1 of this embodiment, two of the cords 2 are inserted into the socket 11, the plug 12 is disposed between the two cords 2 in the width direction (Y-axis direction) perpendicular to the insertion direction, and the plug-side connecting rod 50 is formed to extend in the Y-axis direction from the plug main body 40 and has an inclined surface 531 that inclines backward relative to the Y-axis direction as it extends outward in the Y-axis direction. With this configuration, the portion of the cord 2 emerging from the insertion opening 10 of the socket 11 toward the plug 12 can be guided outward in the Y-axis direction so that the two cords 2 are spaced apart from each other.

[0049] (4) In the cord stopper 1 of this embodiment, a front guide groove 212 extending along the X-axis direction is formed on the inner surface 21B of the front portion 21, a back guide groove 222 extending along the X-axis direction is formed on the inner surface 22B of the back portion 22, and the plug main body 40 has guided portions (front guided portion 411, back guided portion 421) of corresponding shapes so as to be guided by the front guide groove 212 and the back guide groove 222, respectively, and in the Y-axis direction, the width dimensions W1, W2 of the front guide groove 212 and the back guide groove 222 are different from each other. According to this configuration, the width dimensions of the front guide groove 212 and the back guide groove 222 are different from each other, so that, for example, when an attempt is made to insert the plug 12 into the socket 11 upside down, the width dimensions of either the front guide groove 212 or the back guide groove 222 do not match with either the back guided portion 421 or the front guided portion 411, and therefore the plug 12 cannot be inserted by mistake upside down into the socket 11, thereby preventing the plug 12 from being mistakenly inserted into the socket 11 upside down.

[0050] (5) In the cord stopper 1 of this embodiment, the length of the front surface 21 in the X-axis direction is greater than the length of the back surface 22 in the X-axis direction. This configuration increases the area of ​​the plug 12 covered by the front surface 21 of the socket 11, making the plug 12 less noticeable from the front. It also increases the area of ​​the outer surface 21A of the front surface 21 of the socket 11, allowing various logos and the like to be displayed on the front surface, improving the design.

[0051] (6) In the cord stopper 1 of this embodiment, the width dimension of the surface portion 21 in the Y-axis direction increases in the X-axis direction toward the insertion side of the plug 12. This configuration allows the area of ​​the outer surface 21A of the surface portion 21 of the socket 11 to be further increased, and various logos and the like can be displayed enlarged on the surface portion 21, thereby improving the design.

[0052] (7) In the cord stopper 1 of this embodiment, the surface portion 21 is formed with a protrusion 211 that protrudes outward from a position opposite the insertion side of the plug 12 in the X-axis direction. With this configuration, when operating the cord stopper 1, particularly when pulling the plug 12 away from the socket 11 in the X-axis direction, the socket 11 can be stably held by hooking a finger on the protrusion 211, thereby enabling smoother operation of the cord stopper 1.

[0053] (8) In the cord stopper 1 of this embodiment, the socket 11 has a side surface 23 that is continuous with the front surface 21 and the back surface 22, and the end of the side surface 23 on the insertion side of the plug 12 constitutes the bottom surface of a recess 24 that is formed in cooperation with the front surface 21 and the back surface 22. With this configuration, by forming the recess 24, it is possible to increase the area in the Y-axis direction for the cord 2 that comes out from the insertion opening 10 of the socket 11 toward the plug 12.
