[0020] [Configuration of this Embodiment] Hereinafter, embodiments of the present invention will be described based on the drawings. In Figures 1 to 4, the connector 1 according to this embodiment comprises a main body 4 made of synthetic resin having a hook portion 2 on which a fastened object (not shown) such as a string or belt is fastened and a hook opening 20 through which the fastened object passes is formed, and an insertion hole 3 having an entrance 3A and an exit 3B that communicates with the entrance 3A and opens towards the hook opening 20, and an insert 5 that is inserted into the insertion hole 3. The main body 4 further has a connecting portion 6 at a position different from the position of the hook portion 2 to which a fastened object (not shown) such as a string or belt is connected, and the insertion hole 3 is formed across the hook portion 2 and the connecting portion 6. The main body 4 is integrally formed from a single member having the aforementioned hook portion 2 and connecting portion 6 and having the insertion hole 3, and the insert 5 has an insertion main body portion 50 that is inserted into the insertion hole 3 from the entrance 3A, and an opening / closing portion 7 that is connected to the insertion main body portion 50 and protrudes from the exit 3B so as to be able to open and close the hook opening 20. The insertion body portion 50 is made of a synthetic resin material, the same material as the main body 4, while the opening / closing portion 7 is made of a spring member 71 made of metal wire and is connected to the insertion body portion 50. Therefore, the insertion body 5 is made of two members: the insertion body portion 50 and the spring member 71. In the following description, for the sake of explanation, the left-right direction of the connector 1 is defined as the X-axis direction, the thickness direction of the connector 1 is defined as the Y-axis direction, and the up-down direction of the connector 1 is defined as the Z-axis direction. The X, Y, and Z axis directions are orthogonal to each other. One direction in the X-axis direction is defined as the +X-axis direction and the other direction in the X-axis direction is defined as the -X-axis direction, one direction in the Y-axis direction is defined as the +Y-axis direction and the other direction in the Y-axis direction is defined as the -Y-axis direction, and one direction in the Z-axis direction (up in this embodiment) is defined as the +Z-axis direction and the other direction in the Z-axis direction (down in this embodiment) is defined as the -Z-axis direction.

[0021] [Main body] As shown in Figures 1 and 2, the main body 4 has a hook portion 2 formed on the -Z axis side and a connecting portion 6 positioned on the +Z axis side. The connecting portion 6 is located on the +Z axis side of the hook portion 2 with respect to the base portion 21, which will be described later, and cooperates with the base portion 21 to form a connecting hole portion 6A along the X axis direction through which the connected object passes. The connecting portion 6 has a main body portion extending in the X axis direction and side bars 214 extending from both ends of the main body portion toward the base portion 21 and located around the connecting hole portion 6A.

[0022] The hook portion 2 includes a base portion 21, a first arm portion 22 extending in the -Z axis direction from the +X axis side end of the base portion 21, a second arm portion 23 extending in the -X axis direction from the lower end of the first arm portion 22, and a hook arm portion 25 having a fitted portion 24 formed at the -X axis side end of the second arm portion 23 into which the spring member 71 is releasably fitted. The fitted portion 24 constitutes the tip portion 2A of the hook portion 2, and the portion of the base portion 21 on the -X axis side constitutes the base end portion 2B. The tip portion 2A and the base end portion 2B form a hook opening 20.

[0023] The base end portion 2B protrudes toward the -Z axis direction (towards the tip portion 2A). An outlet 3B is formed at the protruding portion of the base end portion 2B, opening toward the hook opening 20. An inlet 3A is formed at the side end face 41 of the main body 4 toward the -X axis direction, extending from the connecting portion 6 or side bar 214 to the aforementioned protruding portion of the base portion 21. The main body 4 also has a pair of side plate portions 211 that face each other in the Y axis direction and form a pair of inner surfaces 31 in the insertion hole 3, and a receiving piece portion 212 that is continuous with the pair of side plate portions 211 on the outlet 3B side and receives the insertion main body portion 50. The inlet 3A and outlet 3B of the insertion hole 3 are separated by the receiving piece portion 212, respectively. The pair of side plate portions 211 have a pair of restricting pieces 213 that extend toward each other in the Y axis direction. A pair of inner surfaces 31 have a continuous inclined surface 32 that slopes toward the exit 3B side, and a recessed portion 33 that is recessed toward the +X axis direction on the -Z axis side of the inclined surface 32, serving as an engaging portion. The inclined surface 32 slopes diagonally downward from the -X axis side toward the +X axis side. An inclined recess 321 is formed in the inclined surface 32. The recess 33 is open toward the exit 3B side and is formed so that a claw portion 524A, described later, can be inserted and engaged into it.

[0024] [Insertion] As shown in Figure 3, the insertion body portion 50 of the insertion body 5 has a wide portion 51 which is formed to be wide in the Y-axis direction, and a narrow portion 52 which is formed to be narrower in the Y-axis direction than the wide portion 51 and is arranged to face a pair of restricting pieces 213 in the Y-axis direction.

[0025] The wide portion 51 has a substantially rectangular outer surface 511 (see Figure 1) that fills the entrance 3A of the insertion hole 3, a pair of side surfaces 512 that are continuous with the side edge of the outer surface 511, and an inclined surface 513 that is continuous with the pair of side surfaces 512 at a position on the +Z axis side of the narrow portion 52. Furthermore, in the portion of the wide portion 51 on the -X axis side, the upper part protrudes in the +Z axis direction, and the lower part extends in the -Z axis direction to a position opposite the narrow portion 52 and to a position where it is received by the receiving piece 212. The inclined surface 513 is inclined so as to be able to abut along the inclined surface 32 of the main body 4. An inclined projection 514 that fits into the inclined recess 321 is formed on the inclined surface 513.

[0026] The narrow portion 52 has a narrow main body portion 520 having a first connecting hole 521 into which one end 711 of the spring member 71 is inserted, and a second connecting hole 522 which is located on the +Z axis side of the first connecting hole 521 and into which the other end 712 of the spring member 71 is inserted. The narrow main body portion 520 also has an elastic piece 524 which is located on the +X axis side with a gap 523 between it and the narrow main body portion 520 and extends on the -Z axis side, and is elastically deformable and resilient. A claw portion 524A is formed at the tip of the elastic piece 524 on the -Z axis side, which engages with the recess 33. The elastic piece 524 with the claw portion 524A forms an engaging portion that engages with the recess 33. The lower part of the narrow portion 52 is located on the -Z axis side of the lower part of the wide portion 51, and for this reason, the insertion main body portion 50 has a stepped portion 50A that fits into the receiving piece portion 212.

[0027] The first connecting hole 521 and the second connecting hole 522 penetrate in the Y-axis direction. The narrow main body portion 520 has a groove-shaped first guide groove 525 which is open at least one end and extends to the first connecting hole 521 and guides one end 711 of the spring member 71 into the first connecting hole 521, and a groove-shaped second guide groove 526 which is open at least one end and extends to the second connecting hole 522 and guides the other end 712 of the spring member 71 into the second connecting hole 522. These first guide grooves 525 and second guide grooves 526 are formed so that when the spring member 71 is attached to the insertion body 50, both ends 711 and 712 of the spring member 71 can move through the gap 523 to the first connecting hole 521 and the second connecting hole 522 and be inserted into the first connecting hole 521 and the second connecting hole 522. As the spring member 71 is attached to the insertion body 50, the groove-shaped first guide grooves 525 and second guide grooves 526 are formed so that both ends 711 and 712 of the spring member 71 can be guided, and the spring member 71 can be easily attached to the insertion body 50.

[0028] In the aforementioned insertion body portion 50, a pair of contact surfaces 53 that abut against the aforementioned pair of restricting pieces 213 are formed along the X-axis direction between the wide portion 51 and the narrow portion 52.

[0029] The spring member 71 is configured as a separate component from the insertion body 50 and has a pair of spring arms 713 and 714 extending in the Z-axis direction, and a fitting portion 715 that is continuous with the lower ends of the spring arms 713 and 714 and releasably fitted into the fitting portion 24 of the hook portion 2. The spring arm 714 is formed to be longer than the spring arm 713. The end 711 of the spring arm 713 on the +Z-axis side is bent in the -Y-axis direction, and the end 712 of the spring arm 714 on the +Z-axis side is bent in the +Y-axis direction. Both ends 711 and 712 are inserted and connected to the insertion body 50 by the first connecting hole 521 and the second connecting hole 522, respectively, so as to sandwich the insertion body 50 in the Y-axis direction, and are arranged surrounded by the insertion hole 3, and in particular in the Y-axis direction they are arranged facing the inner surfaces 31 of the pair of side plate portions 211.

[0030] In the aforementioned connector 1, the insert 5 is inserted into the insertion hole 3 and attached to the main body 4 in the following manner.

[0031] First, the spring member 71 is inserted into the insertion hole 3 from the inlet 3A, and the insertion body 50 is inserted into the insertion hole 3 from the inlet 3A while the spring member 71 is protruding from the outlet 3B.

[0032] Next, the lower part of the insertion body 50, specifically the lower part of the wide portion 51 as shown in Figure 4, is brought into contact with the receiving piece 212, and the insertion body 50 is rotated into the insertion hole 3. At this time, the inclined surface 32 comes into contact with the inclined surface 513 and is guided in the insertion direction by the inclined surface 513.

[0033] Next, the claw portion 524A presses against the insertion hole 3, causing the elastic piece 524 to elastically deform in the -X axis direction. When the claw portion 524A is positioned opposite the recess 33 in the X axis direction, the elastic deformation of the elastic piece 524 is restored, and the claw portion 524A moves in the -X axis direction and is inserted into the recess 33, engaging with the recess 33. As a result, the insert 5 is mounted on the main body 4.

[0034] At this time, the stepped portion 50A of the insertion body portion 50 fits with the receiving piece portion 212, and the inclined convex portion 514 fits with the inclined recess portion 321. The outer surface 511 of the insertion body portion 50 is arranged flush with the side end surface 41 on the -X axis side of the main body 4. The connection portion between the insertion body portion 50 and the opening / closing portion 7, in this embodiment, the connection portion between the insertion body portion 50 and the spring member 71 is arranged surrounded by the insertion hole 3. Therefore, the operating range of the spring member 71 can be restricted in the direction of opening and closing the hook opening 20, and the opening and closing operation of the spring member 71 can be stabilized.

[0035] In the aforementioned mounting state, a gap 80 in the X-axis direction is formed within the insertion hole 3 between the claw portion 524A and the recess 33. Therefore, by inserting a finger or the like into this gap 80, the elastic piece 524 can be elastically deformed to release the engagement of the claw portion 524A with the recess 33, thereby allowing the insert 5 to be easily removed from the main body 4. Furthermore, since the aforementioned gap 80 is located within the insertion hole 3, the risk of the engagement of the claw portion 524A with the recess 33 being unexpectedly released during normal use of the connector 1 is reduced.

[0036] [Modified Version] In the above embodiment, the opening / closing part 7 is made of a spring member 71 which is a separate component from the insertion body part 50. However, it is not limited to this, and may be integrally and continuously constructed with the insertion body part 50, for example, as shown in Figure 5. In this case, the opening / closing part 7 is made of synthetic resin, just like the insertion body part 50. Also, in the mounted state in which the insert body 5 is attached to the main body 4, the continuous portion of the opening / closing part 7 and the insertion body part 50 is arranged surrounded by the insertion hole 3.

[0037] In the above embodiment, a first guide groove 525 and a second guide groove 526 are formed, but the embodiment is not limited to this, and the configuration of either or both of the first guide groove 525 and the second guide groove 526 may be omitted.

[0038] In the above embodiment, the claw portion 524A of the elastic piece 524 is inserted into and engaged with the recess 33, but the embodiment is not limited to this, and other forms of engaging and engaged portions may be configured on the insert 5 and the main body 4 as long as the insert 5 can be attached to the main body 4. For example, the insert 5 may be screwed to the main body 4.

[0039] In the above embodiment, a gap 80 is formed between the claw portion 524A and the concave portion 33. However, the present invention is not limited to this, and the gap 80 may be eliminated and the claw portion 524A may contact the bottom portion on the -X axis direction side of the concave portion 33. Further, the elastic piece 524 may be in a state where it is slightly press - contacted with the bottom portion of the concave portion 33, and a slight elastic force in the +X axis direction may be constantly applied to the elastic piece 524 so as to reduce the play between the insertion main body portion 50 and the main body 4 as much as possible.

[0040] In the above embodiment, the inclined convex portion 514 is formed on the insert 5. However, the present invention is not limited to this, and an inclined concave portion substantially similar to the inclined concave portion 321 may be formed. In this case, on the main body 4, an inclined convex portion substantially similar to the inclined convex portion 514 is formed so as to be fitted with the inclined concave portion instead of the inclined concave portion 321.

[0041] In the above embodiment, the inclined surfaces 32 and 513 are formed. However, the present invention is not limited to this, and if the insertion main body portion 50 can be appropriately arranged in the insertion hole 3, the configuration of the inclined surfaces 32 and 513 may be omitted.

[0042] In the above embodiment, the insertion hole 3 is formed across the base portion 21 and the connecting portion 6 of the hook portion 2. However, the present invention is not limited to this, and for example, it may be formed only in the base portion 21.

[0043] In the above embodiment, the base end portion 2B of the hook portion 2 is formed to protrude toward the tip end portion 2A side. However, the present invention is not limited to this, and the protrusion may not be formed.

[0044] In the above embodiment, the hook portion 2 and the connecting portion 6 are integrally and continuously formed on the main body 4. However, the present invention is not limited to this, and the hook portion 2 and the connecting portion 6 may be constituted by separate members, and the main body may be constituted by combining these with each other.

[0045] In the above embodiment, the connecting portion 6 forms the connecting hole portion 6A. However, the present invention is not limited to this, and for example, it may be formed by a slit (not shown) that opens on the +X axis direction side or the -X axis direction side.

[0046] In the above embodiment, the connecting portion 6 is configured on the main body 4. However, the present invention is not limited to this, and the configuration of the connecting portion 6 may be omitted. Even in this case, the hook portion 2 is connected by hanging a latching body thereon.

[0047] In the above embodiment, the inlet 3A of the insertion hole 3 is formed to open at the side end surface 41 of the main body 4. However, the present invention is not limited to this. As long as the insertion body 5 can be attached to the main body 4, for example, instead of or in addition to the inlet 3A that opens at the side end surface 41, an inlet that opens at at least one of the pair of side plate portions 211 may be configured.

[0048] In the above embodiment, the main body 4 is made of synthetic resin. However, the present invention is not limited to this, and for example, it may be made of metal.

[0049] [Summary of the Embodiment] (1) The connector 1 of the present embodiment includes a main body 4 having a hook portion 2 in which a hook opening 20 is formed, and an insertion hole 3 having an inlet 3A and an outlet 3B that communicates with the inlet 3A and opens toward the hook opening 20 side, and an insertion body 5 inserted into the insertion hole 3. The insertion body 5 has an insertion main body portion 50 inserted into the insertion hole 3 from the inlet 3A, and an opening / closing portion 7 that is continuous with the insertion main body portion 50 and protrudes from the outlet 3B and is disposed so as to be able to open and close the hook opening 20. The continuous portion between the insertion main body portion 50 and the opening / closing portion 7 is disposed surrounded by the insertion hole 3. According to the connector 1, by surrounding the connection portion between the insertion main body portion 50 and the opening / closing portion 7 with the insertion hole 3, it is possible to stabilize the opening and closing of the hook opening 20 by the opening / closing portion 7. In addition, since the connector 1 is configured by inserting the insertion body 5 into the insertion hole 3 of the main body 4, it is possible to eliminate the configuration of covering the main body 4, eliminate the possibility of the connector 1 becoming large, and reduce the constraints on the design freedom of the connector 1.

[0050] (2) In the connector 1 of the present embodiment, the opening / closing portion 7 is configured as a separate member with respect to the insertion main body portion 50 and is connected to the insertion main body portion 50. According to such a configuration, since the connection portion between the insertion main body portion 50 and the opening / closing portion 7, which is a separate member, is surrounded by the insertion hole 3, for example, even if a load is applied to the opening / closing portion 7, it is possible to suppress the opening / closing portion 7 from detaching from the insertion main body portion 50 by the insertion hole 3 of the main body 4.

[0051] (3) In the connector 1 of this embodiment, the opening and closing part 7 is made of a spring member 71 made of metal wire, and both ends 711 and 712 of the spring member 71 are connected to the insertion body 50 so as to sandwich the insertion body 50 and are arranged surrounded by the insertion hole 3. With this configuration, for example, even if a load is applied to the opening and closing part 7, the insertion hole 3 of the main body 4 can prevent both ends 711 and 712 of the opening and closing part 7, which are made of metal wire, from opening and deforming, and the opening and closing part 7 can be prevented from coming off the insertion body 50.

[0052] (4) In a modified example of the connector 1 of this embodiment, the opening and closing portion 7 is integrally and continuously configured with respect to the insertion body portion 50. With this configuration, the connector 1 can be constructed with only two members, the body 4 and the insertion body 5, thereby simplifying the configuration of the connector 1.

[0053] (5) In the connector 1 of this embodiment, the insertion body portion 50 has a first connecting hole 521 into which one end 711 of the spring member 71 is inserted, a second connecting hole 522 into which the other end 712 of the spring member 71 is inserted, and at least one of a groove-shaped first guide groove 525 that guides one end 711 of the spring member 71 into the first connecting hole 521 and a groove-shaped second guide groove 526 that guides the other end 712 of the spring member 71 into the second connecting hole 522. With this configuration, when connecting the spring member 71 to the insertion body portion 50, the end 711 (712) of the spring member 71 can be guided into the first connecting hole 521 or the second connecting hole 522 by the guide groove 525 (526), ​​thereby improving ease of assembly. Furthermore, by forming groove-shaped guide grooves 525 (526) in the insertion body portion 50, the insertion amount of the ends 711 (712) of the spring member 71 into the first connecting hole 521 and the second connecting hole 522 is reduced. Compared to a configuration where guide grooves 525 (526) are not formed, the ends 711 (712) of the spring member 71 are more likely to come out of the first connecting hole 521 and the second connecting hole 522. In this embodiment, the connection portion between the insertion body portion 50 and the opening / closing portion 7, in this case the connection portion between each end 711, 712 of the spring member 71 and the first connecting hole 521 and the second connecting hole 522, is surrounded by the insertion hole 3. For example, when a load is applied to the spring member 71, it is possible to suppress the spring member 71 from bending significantly and coming out of the insertion body portion 50.

[0054] (6) In the connector 1 of this embodiment, an engaging portion is formed on the insertion body portion 50, and an engaged portion is formed on the insertion hole 3 with which the engaging portion engages. The engaging portion engages with the engaged portion when the insertion body portion 50 is inserted into the insertion hole 3. With this configuration, since the engaging portion engages with the engaged portion in the aforementioned mounted state, the mounting state of the insert 5 to the body 4 can be made stronger.

[0055] (7) In the connector 1 of this embodiment, the engaging portion has an elastic piece 524 with a claw portion 524A formed at its tip, and the engaged portion has a recess 33 into which the claw portion 524A is inserted and engaged. The elastic piece 524 is configured to be elastically deformed when the claw portion 524A is pressed against the insertion hole 3, and to return to its original shape when the claw portion 524A is inserted into the recess 33. With this configuration, as described above, by utilizing the elastic force of the elastic piece 524 which is elastically deformable and can be restored, the insertability of the insertion body portion 50 into the insertion hole 3 can be improved, and the inserted engagement state of the claw portion 524A with respect to the recess 33 can be suitably maintained.

[0056] (8) In the connector 1 of this embodiment, the recess 33 is open to the exit 3B side, and when the claw portion 524A and the recess 33 are engaged, a gap 80 is formed between the claw portion 524A and the recess 33. With this configuration, for example, when replacing or repairing the insert 5, the claw portion 524A can be removed from the recess 33 by pressing the claw portion 524A while widening the gap 80 with the fingers, thereby elastically deforming the elastic piece 524. This allows the insert body portion 50 to be easily removed from the entrance 3A of the insertion hole 3, and the insert 5 can be easily removed from the body 4. Note that since the gap 80 is inside the insertion hole 3, the risk of the claw portion 524A unexpectedly coming out of the recess 33 is reduced.

[0057] (9) In the connector 1 of this embodiment, the main body 4 has a pair of side plate portions 211 that face each other in the Y-axis direction, which is the thickness direction, and form the inner surface 31 of the insertion hole 3, the pair of side plate portions 211 have restricting pieces 213 that extend toward each other in the Y-axis direction, which is the thickness direction, and the insertion main body portion 50 has a contact surface 53 that abuts against the restricting pieces 213. With this configuration, when the insertion body is attached, the contact surface 53 abuts against the restricting pieces 213, and the swinging of the insertion main body portion 50 is restricted by the restricting pieces 213, so that the attachment state of the insert 5 to the main body 4 can be made stronger, and the strength of the attachment portion of the insert 5 and its surroundings can also be improved.

[0058] (10) In the connector 1 of this embodiment, the main body 4 has an inclined surface 32 that is continuous with the inner surfaces 31 of the pair of side plate portions 211 and inclined toward the exit 3B side, the insertion main body portion 50 has an inclined surface 513 that is inclined to be able to abut along the inclined surface 32, an inclined protrusion 514 is formed on one of the inclined surfaces of the insertion main body portion 50 and the insertion hole 3, and an inclined recess 321 is formed on the other of the insertion main body portion 50 and the insertion hole 3 into which the inclined protrusion 514 is fitted. With this configuration, the insertion of the insertion main body portion 50 into the insertion hole 3 can be improved by forming the aforementioned inclined surfaces 32 and 513, and the mounting state of the insert 5 to the main body 4 can be more firmly reinforced by positioning the inclined protrusion 514 in the inclined recess 321.

[0059] (11) In the connector 1 of this embodiment, the hook portion 2 has a base portion 21 and a hook arm portion 25 extending from the base portion 21, the main body 4 further has a connecting portion 6 to which a connected object is connected at a position different from the position of the hook portion 2, the connecting portion 6 cooperates with the base portion 21 to form a connecting hole portion 6A through which the connected object is passed, the connecting portion 6 has a side bar 214 that extends toward the base portion 21 and is located around the connecting hole portion 6A, and the insertion hole 3 is formed across the base portion 21 and the side bar 214. With this configuration, since the insertion hole 3 is formed across the base portion 21 and the aforementioned side bar 214, the positions of the hook portion 2 and the connecting portion 6 can be brought closer together to construct the connector 1, and the connector 1 can be made smaller.

[0060] (12) In the connector 1 of this embodiment, the main body 4 is formed with a pair of side plate portions 211 that form a pair of inner surfaces 31 in the insertion hole 3, and a receiving piece portion 212 that is continuous with the pair of side plate portions 211 and receives the insertion main body portion 50, and the entrance 3A and the exit 3B are respectively demarcated by the receiving piece portion 212. With this configuration, the strength of the portion that forms the insertion hole 3 can be improved by using the receiving piece portion 212 that receives the insertion main body portion 50 as a configuration that demarcates the entrance 3A and the exit 3B of the insertion hole 3.

[0061] (13) In the connector 1 of this embodiment, the hook opening 20 is formed by the tip portion 2A and the base portion 2B of the hook portion 2, the base portion 2B is formed to protrude toward the tip portion 2A, and the outlet 3B is formed at the base portion 2B. With this configuration, the connector 1 can be configured with the positions of the hook portion 2 and the connector 6 closer together, thereby enabling further miniaturization of the connector 1.
