By connecting the male connector 510 to the inside of the female connector 520, the line-shaped accessory becomes a ring shape, and is hung, for example, around the user's neck. By removing the male connector 510 from the female connector 520, the line-shaped accessory becomes a single line.

  As shown in FIG. 15, the male connector 510 includes a rod-shaped body 511 and a coupling ring 512 attached to one end of the rod-shaped body 511.

  A ring-shaped groove 511 </ b> C is formed near one end of the rod-shaped body 511. The rod-shaped body 511 includes a first portion 511A having a constant outer diameter and a second portion 511B having a gradually decreasing outer diameter as it approaches the tip.

  One end 531 of the line accessory is connected to the connecting ring 512.

  For example, the locking device 3 described in FIG. 1 of Japanese Patent Laid-Open No. 9-182609 has the same structure as the male connector 510.

  The female connector 520 includes a first cover member 521, a second cover member 522, and a coil spring 523.

  The first cover member 521 opens downward, a notch 521A is formed at the upper end of the side wall 522C, and a connecting ring 524 is attached to the other end. The other end 532 of the line accessory is connected to the connecting ring 524.

  The second cover member 522 opens upward, and a notch 522A is formed at one end. The notch 521A of the first cover member 521 and the notch 522A of the second cover member 522 are aligned in the vertical direction to form an opening when the male connector 510 is inserted into the female connector 520. Yes.

  The first cover member 521 and the second cover member 522 are connected to each other via a central shaft 525 so as to be rotatable.

  The second cover member 522 is formed smaller than the first cover member 521, and one end 522 </ b> B of the second cover member 522 is in a position where it can be rotated without interfering with the first cover member 521.

  The coil spring 523 is housed in a first cover member 521 and a second cover member 522 that are rotatably connected to each other, and the first cover member 521 and the second cover member 522 are closed together. That is, the first cover member 521 biases the first cover member 521 and the second cover member 522 in the clockwise direction around the central axis 525, and the second cover member 522 biases the first cover member 521 and the second cover member 522 in the counterclockwise direction around the central axis 525, respectively. ing. For this reason, in the normal state, as shown in FIG. 15, the first cover member 521 and the second cover member 522 are in a closed state.

  The conventional jewelry connecting tool 500 is used as follows.

  FIG. 16 is a longitudinal sectional view of the male connector 510 inserted into the female connector 520.

  When the male connector 510 is inserted into the opening formed by the notch 521A of the first cover member 521 and the notch 522A of the second cover member 522, the outer diameter of the second portion 511B of the male connector 510 gradually increases. The opening is gradually widened in the vertical direction in response to the increase. That is, the first cover member 521 rotates counterclockwise about the central axis 525, and the second cover member 522 rotates clockwise about the central axis 525.

  When the male connector 510 is further pushed into the female connector 520, the groove 511C of the male connector 510 reaches a position where it is aligned with the side wall 522C of the second cover member 522. When the male connector 510 reaches this position, the second cover member 522 that has been rotated clockwise by the first portion 511A of the rod-like body 511 does not have the pressing force by the first portion 511A of the rod-like body 511. In response to the elastic force of the coil spring 523, the coil spring 523 rotates clockwise. That is, the side wall 522C of the second cover member 522 moves upward in FIG. 15, and is fitted into the groove 511C from below.

  FIG. 16 shows a state in which the side wall 522C of the second cover member 522 is fitted in the groove 511A of the male connector 510. In this state, since the side wall 522C of the second cover member 522 is fitted in the groove 511A of the male connector 510, the male connector 510 is locked inside the female connector 520. Further, as shown in FIG. 16, the inner wall 521B of the first cover member 521 supports the rod-shaped body 511 from above, and the inner wall 522D of the second cover member 522 supports the rod-shaped body 511 from below.

  In order to extract the male connector 510 from the female connector 520, the region of the second cover member 522 opposite to the notches 521A and 522A with respect to the central shaft 525 (the region on the left side of the central shaft 525 in FIG. 16). Is pushed upward as indicated by arrow Y. That is, the second cover member 522 is rotated clockwise about the central axis 525.

  Note that a concave portion 522E is formed in the second cover member 522 in order to show a place where the second cover member 522 is pushed up.

  When the second cover member 522 is pushed upward as indicated by the arrow Y, the second cover member 522 rotates clockwise about the central axis 525, and as a result, the side wall 522C of the second cover member 522 Rotating downward, the engagement between the side wall 522C of the second cover member 522 and the groove 511C of the male connector 510 is released.

  Accordingly, the lock between the male connector 510 and the female connector 520 is released, and the male connector 510 can be extracted from the female connector 520.

  After the male connector 510 is removed from the female connector 520, if the second cover member 522 is stopped from being pushed upward (that is, if the finger is released from the second cover member 522), the elastic force of the coil spring 523 The second cover member 522 returns to the original position. That is, the first cover member 521 and the second cover member 522 return to the state shown in FIG.

  FIG. 17 is an exploded view of a second example of a conventional accessory connector.

  17 includes a male connector 610 and a female connector 520. Compared to the conventional accessory connector 500 shown in FIGS. 15 and 16, the male connector 610 is a male connector. Only the shape of the tool 610 is different.

  FIG. 18 is a longitudinal sectional view of the male connector 610 inserted into the female connector 520.

  As shown in FIG. 17, the male connector 610 in the jewelry accessory 600 includes a rod-shaped body 611 and a connection ring 612 attached to one end of the rod-shaped body 611.

  A ring-shaped groove 611D is formed near one end of the rod-shaped body 611. The rod-shaped body 611 has a first portion 611A having a constant outer diameter, a second portion 511B having a gradually decreasing outer diameter as it approaches the tip, and a constant outer diameter that is smaller than the outer diameter of the first portion 611A. And a third portion 611C having a hemispherical tip.

  The method of using the jewelry accessory 600 is the same as the method of using the jewelry connector 500.

JP-A-9-182609

  As described above, the rod-like bodies 511 and 611 constituting the male couplers 510 and 610 in the conventional jewelry couplers 500 and 600 are provided at the portions ahead of the grooves 511C and 611D with which the female coupler 520 is engaged. It is comprised from the part 511A, 611A where an outer diameter is constant, and the part 511B, 611C where the front-end | tip is thin.

  When the male couplers 510 and 610 are inserted into the female coupler 520, it is required that the male couplers 510 and 610 can be smoothly inserted. Alternatively, it is essential to make the tip thin.

  If the outer diameters of the rod-like bodies 511 and 611 are made constant or the tip is made thin, the male couplers 510 and 610 can be smoothly inserted into the female coupler 520, but on the other hand, Such disadvantages occur.

  When the male couplers 510 and 610 are inserted into the female coupler 520, a line-shaped accessory is hung around the neck, and the male couplers 510 and 610 are inserted into the female coupler 520 using both hands on the back side of the neck. Often it will fit into. In such a case, since the user cannot visually confirm, the male couplers 510 and 610 are inserted into the female coupler 520 depending only on the feeling of both hands.

  However, if the male couplers 510 and 610 can be smoothly inserted into the female coupler 520, the feeling when the male couplers 510 and 610 are inserted into the female coupler 520 and the male couplers 510 and 610 On the contrary, for the user, the male couplers 510 and 610 are connected to the female coupler 520 because the feel when the male couplers 510 and 610 are pushed without being inserted into the female coupler 520 is the same. It becomes difficult to determine whether or not it is securely inserted. Therefore, even if the user himself / herself determines that the male couplers 510 and 610 have been inserted into the female coupler 520, the male couplers 510 and 610 are not actually inserted into the female coupler 520. If the user removes his / her hands from the male couplers 510 and 610 and the female coupler 520, the accessory may fall.

  The present invention has been made in view of the problems in such a conventional accessory connector, and the male connector is connected to the female connector at a location where the user cannot confirm with his / her eyes (for example, the back side of the neck). It is an object of the present invention to provide a male connector or a connector for jewelry that can confirm that the male connector is securely connected to the female connector even if the connector is connected to the connector.

  In order to achieve the above object, the present invention is a jewelry connector comprising: a male connector capable of connecting one end of a line-shaped accessory; and a female connector capable of connecting the other end of the jewelry. The female connector can be locked in a state where the male connector is inserted therein, and the lock on the male connector is released according to a predetermined operation by the user with respect to the female connector. The male connector in the jewelry connector that enables the male connector to be extracted, wherein the male connector is a rod-shaped body, and the rod-shaped body is engaged with the female connector. The portion of the rod-like body in front of the groove has a first portion having a first outer diameter as a maximum outer diameter and a maximum outer diameter smaller than the first outer diameter from the tip thereof. A second part having, in this order, The first outer diameter is a size that causes contact resistance between the male connector and the opening of the female connector when the male connector passes through the opening of the female connector. A male connector is provided.

  The first outer diameter is preferably the maximum outer diameter within a range that can be inserted into the opening of the female connector.

  It is preferable that the first portion has an outwardly convex curved shape and the second portion has an inwardly convex curved shape.

  The male connector according to the present invention preferably further includes a third portion that is continuous with the second portion and has a maximum outer diameter that is larger than the maximum outer diameter of the second portion.

  It is preferable that a step is formed at the boundary between the first part and the second part.

  The present invention further relates to a jewelry connector comprising the above-described male connector and a female connector capable of connecting the other end of the jewelry, wherein the female connector includes the male connector inside. An accessory that can be locked in the inserted state and that can unlock the male connector and remove the male connector in accordance with a predetermined operation by the user with respect to the female connector. A connecting tool is provided.

  Whereas the distal end portions of the male couplers 510 and 610 in the conventional accessory couplers 500 and 600 are set to have a constant outer diameter or gradually decrease in outer diameter, In the connector, the tip portion is set to be thick, contrary to the conventional accessories couplers 500 and 600. For this reason, when the first part of the male connector is passed through the opening of the female connector, a large contact resistance is generated. Thus, for the user of the coupling tool for jewelry, a large contact resistance is felt when the first part of the male coupling tool is passed through the opening of the female coupling tool, and the male coupling tool is securely connected to the female coupling tool. It is possible to realize that it is being inserted inside.

  Further, when the male connector is pulled out of the female connector, contact resistance is generated when the first portion of the male connector passes through the opening of the female connector. It is possible to surely feel that the connector is being pulled out.

  As described above, when the male connector is inserted into the female connector by using the male connector according to the present invention, the first portion of the male connector passes through the opening of the female connector. The resulting contact resistance allows the user to realize that the male connector is being inserted into the female connector, so that the male connector can be reliably locked to the female connector. . Unlike the conventional accessories couplers 500 and 600, it is no longer possible to determine whether or not the male connector 100 can be reliably inserted into the female connector 520.

  In the conventional accessories couplers 500 and 600, it was important to smoothly insert the male couplers 510 and 610 into the female coupler 520, so that the distal ends of the male couplers 510 and 610 are closer to the base end side. The idea of making it thicker could not arise. On the other hand, the male connector according to the present invention has a beneficial effect on the user as described above by overturning such an idea.

(First embodiment)
FIG. 1 is an exploded view of a jewelry connector 150 using a male connector 100 according to a first embodiment of the present invention.

  The male connector 100 according to the present embodiment constitutes a jewelry connector 150 together with the female connector 520.

  FIG. 2 is a plan view of the male connector 100 according to this embodiment, and FIG. 3 is a perspective view of the male connector 100 according to this embodiment.

  As shown in FIGS. 1 to 3, the male connector 100 includes a rod-shaped body 110 and a coupling ring 120 attached to one end of the rod-shaped body 110.

  One end 531 of the line accessory is connected to the connecting ring 120.

  A ring-shaped groove 111 is formed near one end of the rod-shaped body 110.

  The portion of the rod-shaped body 110 in front of the groove 111 is continuous from the tip thereof with the first portion 110A having the first outer diameter D1 as the maximum outer diameter and the first portion 110A, and the first outer diameter D1 as the maximum outer diameter. A second portion 110B having a second outer diameter D2 smaller than the second outer diameter D2A and a second outer diameter D2A smaller than the second outer diameter D2 as a minimum outer diameter, and the second portion 110B. A third portion 110C having a third outer diameter D3 larger than the outer diameter D2 is provided in this order.

  The third outer diameter D3 of the third portion 110C is set slightly larger than the first outer diameter D1 of the first portion 110A.

  Further, as shown in FIGS. 1 to 3, the first portion 110A has an outwardly convex curved shape with the first outer diameter D1 as a vertex, and the second portion 110B has a second outer diameter D2 as a vertex. A convex curve is formed on the inner side with the outer diameter D2A as the bottom, and the first portion 110A and the second portion 110B are smoothly continuous in a curved shape. Similarly, the third portion 110C and the second portion 110B are smoothly and continuously curved.

  As described above, schematically, the male connector 100 according to the present embodiment has a structure in which the vicinity of the tip is thick, and becomes thinner as the groove 111 is approached, and then becomes thicker again.

  The outer diameter of the flange 112, which is the portion between the groove 111 and the connecting ring 120, is set to be larger than the first outer diameter D1 and the third outer diameter D3. This is to prevent the male connector 100 from being pushed into the female connector 520 more than necessary.

  Although the usage method of the jewelry connector 150 having the male connector 100 according to the present embodiment is the same as that of the conventional jewelry connector 500 shown in FIGS. 15 and 16, the male connector 100 according to the present embodiment. By using, the jewelry connector 150 exhibits the following effects.

  4 and 5 are vertical cross-sectional views in a state where the male connector 100 is being inserted into the female connector 520, and FIG. 6 is a state in which the male connector 100 has been inserted into the female connector 520. FIG.

  In the conventional accessory fitting 500, the first portion 511A on the proximal end side near the groove 511C of the male connector 510 has a large outer diameter, and the second portion 511B has a gradually decreasing outer diameter. When this is compared with the male connector 100 according to the present embodiment, the outer diameter of the first portion 511A of the male connector 510 is equal to the third outer diameter D3 of the third portion 110C of the male connector 100, and the male connector 510. The outer diameter of the second portion 511B is equal to or smaller than the third outer diameter D3 of the third portion 110C of the male connector 100 (the diameter of any of the second portions 511B of the male connector 510 is the first diameter of the male connector 100). Equal to the second outer diameter D2 of the two portions 110B).

  Further, in the conventional accessory fitting 600, the outer diameter of the first portion 611A on the proximal end side close to the groove 611D of the male connector 610 is large, and the outer diameter of the third portion 611C is small. When this is compared with the male connector 100 according to the present embodiment, the outer diameter of the first portion 611A of the male connector 610 is equal to the third outer diameter D3 of the third portion 110C of the male connector 100, and the male connector 610. The third portion 611C has an outer diameter equal to the second outer diameter D2 of the second portion 110B of the male connector 100.

  In other words, the distal end portions of the male couplers 510 and 610 in the conventional jewelry couplers 500 and 600 are set such that the outer diameter is constant or the outer diameter is gradually reduced. On the contrary, in the male connector 100 according to the above, the tip portion is set to be thick.

  Therefore, as shown in FIG. 4, when the first portion 110 </ b> A of the male connector 100 is passed through the opening of the female connector 520, large contact is made between the first portion 110 </ b> A of the male connector 100 and the female connector 520. Resistance is born. The male connector 100 is further pushed into the female connector 520, the first portion 110A passes completely through the opening of the female connector 520, and the second portion 110B is opened to the female connector 520 as shown in FIG. When reaching the part, there is no contact resistance when passing the first part 110A.

  In this way, for the user of the jewelry accessory 150, when the first portion 110A of the male connector 100 is passed through the opening of the female connector 520, a large contact resistance is felt, and the male connector 100 is securely attached. It is possible to realize that the female connector 520 is being inserted.

  When the male connector 100 is further pushed forward, the third portion 110C hits the opening of the female connector 520. Since the outer diameter D3 of the third portion 110C is set to be slightly larger than the outer diameter D1 of the first portion 110A, when passing the third portion 110C through the opening of the female connector 520, the first portion 110A is inserted into the female connector. A larger contact resistance is produced than when passing through the opening of 520.

  For this reason, for the user of the jewelry accessory 150, the second contact resistance is felt after the contact resistance felt when the first portion 110A is passed through the opening of the female connector 520, and the male connection It can be felt that the tool 100 is being reliably inserted into the female connector 520.

  When the male connector 100 is further pushed forward, the side wall 522C of the second cover member 522 is engaged with the groove 111, so that the male connector 100 is securely locked inside the female connector 520, as shown in FIG. It is possible to confirm that.

  Further, when the side wall 522C of the second cover member 522 is engaged with the groove 111, a small contact sound is generated. For this reason, for the user of the jewelry accessory 150, the male connector 100 causes the female connector 100 to become a female connector. It can be confirmed that it is securely locked inside 520.

  Further, when the male connector 100 is removed from the female connector 520, when the third portion 110C of the male connector 100 passes through the opening of the female connector 520, and when the first portion 110A of the male connector 100 is female. Since the contact resistance is generated twice when passing through the opening of the connector 520, the user can surely realize that the male connector 100 is being removed from the female connector 520. Is possible.

  As described above, when the male connector 100 according to this embodiment is used, when the male connector 100 is inserted into the female connector 520, the first portion 110A and the third portion 110C of the male connector 100 are The contact resistance generated when passing through the opening of the female connector 520 allows the user to feel that the male connector 100 is being inserted into the female connector 520, so that the user can be sure. The male connector 100 can be locked relative to the female connector 520. Unlike the conventional accessory couplers 500 and 600, it can be prevented that it is impossible to determine whether or not the male coupler 100 can be reliably inserted into the female coupler 520.

  In the conventional accessories couplers 500 and 600, since it was important to smoothly insert the male couplers 510 and 610 into the female coupler 520, the idea of making the tips of the male couplers 510 and 610 thicker. Could not occur. On the other hand, the male connector 100 according to the present embodiment has a beneficial effect on the user as described above by changing the conventional idea.

  The male connector 100 according to the present embodiment is not limited to the above structure, and various modifications can be made.

  For example, in the male connector 100 according to the present embodiment, the first outer diameter D1 of the first portion 110A has an outer diameter larger than the second outer diameter D2 that is the maximum outer diameter of the second portion 110B, As long as the outer diameter is such that contact resistance is generated between the first portion 110A of the male connector 100 and the female connector 520 when passing through the opening of the female connector 520, an arbitrary outer diameter is set. It is possible to set. That is, the first outer diameter D1 of the first portion 110A has a maximum outer diameter within a range in which the first portion 110A can be inserted into the opening of the female connector 520, and passes through the opening of the female connector 520. It is possible to set an arbitrary outer diameter between the first portion 110A and the female connector 520 up to a minimum outer diameter within a range in which contact resistance is generated.

  Moreover, although the male connector 100 which concerns on this embodiment is formed as what has the ring-shaped connection ring 120, the shape of the connection ring 120 is arbitrary.

  In the male connector 100 according to the present embodiment, the first outer diameter D1 of the first portion 110A and the third outer diameter D3 of the third portion 110C are set to be equal to each other. It is also possible to set the outer diameter D3 to be smaller or larger than the first outer diameter D1. However, when the third outer diameter D3 is set to be smaller than the first outer diameter D1, contact resistance may not occur when the third portion 110C passes through the opening of the female connector 520.

(Second embodiment)
FIG. 7 is a plan view of the male connector 200 according to the second embodiment of the present invention.

  The male connector 200 according to the present embodiment is different from the male connector 100 according to the first embodiment in that the third portion 110C is not provided.

  As shown in FIG. 7, a portion in front of the groove 111 of the rod-like body 115 of the male connector 200 according to the present embodiment is a first portion 110A having a first outer diameter D1 as a maximum outer diameter from the tip thereof. A second portion 110B that is continuous with the first portion 110A and has a second outer diameter D2 that is smaller than the first outer diameter D1 as the maximum outer diameter is provided in this order.

  That is, in the male connector 200 according to the present embodiment, a portion corresponding to the third portion 110C of the male connector 100 according to the first embodiment is a part of the second portion 110B.

  The same effects as the male connector 100 according to the first embodiment can be obtained by the male connector 200 according to this embodiment.

  Note that, as shown in FIG. 7, the tip of the rod-like body 115 can be tapered as shown by a broken line 113.

(Third embodiment)
FIG. 8 is a plan view of a male connector 300 according to the third embodiment of the present invention.

  In the male connector 100 according to the first embodiment, the first portion 110A, the second portion 110B, and the third portion 110C of the rod-shaped body 110 are formed in an outer or inner convex curved shape, The first portion 110A, the second portion 110B, and the third portion 110C of the rod-like body 116 of the male connector 300 according to the present embodiment are formed as a simple cylindrical shape.
