More specifically, according to the present invention, the connector body and the connection pin can be easily engaged and disengaged by the engagement mechanism, and components such as an elastic member are used in the manufacture of the connection pin of the connection tool for jewelry. The present invention relates to a connecting tool for jewelry that can be easily assembled without caulking with a caulking pin or the like.

  Annular jewelry, for example, a necklace, is used by being connected in an annular shape by a so-called clasp or a connecting tool called a pull ring or hook. Among such connectors, for example, a hook using a leaf spring as disclosed in JP-A No. 2002-219011 (Patent Document 1) is known.

  However, the conventional connector disclosed in Patent Document 1 and the like has a drawback that, for example, when used in a necklace such as a thin chain, the connector main body tends to be larger than the chain thickness and is not preferable as a part of an accessory. It was.

  Needless to say, in general, it is desirable to reduce the number of parts necessary for manufacturing a connector as much as possible and to reduce the cost of the connector without impairing the design of the entire accessory.

  Therefore, in order to solve the above-mentioned problem, the applicant of the present invention is for an accessory that can easily realize engagement / disengagement between a connector main body and a connection pin as disclosed in Japanese Patent Application Laid-Open No. 2009-95637 (Patent Document 2). A coupling tool was proposed. The connecting tool for jewelry disclosed in Patent Document 2 realizes the connection between the connecting tool body and the connecting pin by a connecting mechanism as shown in FIGS. 3A and 3B.

  However, as a result of further studies by the inventor, it has been found that the accessory connecting component of the conventional technique (Patent Document 2) proposed in FIGS. 3A and 3B has the following problems. .

  In the prior art disclosed in Patent Document 2, the connecting pin 5 has to be fixed by caulking the locking push button 4 protruding to the outside from an opening provided in a part thereof (FIG. 3A and FIG. 3). FIG. 3B). In the field of jewelry such as necklaces, it is difficult to adjust the subtle force in the work of assembling each part and caulking with caulking pins, etc. There is a problem that skill is required, and furthermore, in order to provide this “caulking”, problems in manufacturing remain in terms of miniaturization and weight reduction. On the other hand, in order to eliminate such “caulking”, it has been considered that the connecting pin 5 itself is formed of one elastic member such as a spring.

  However, the connecting pin formed in this way has a problem in terms of its strength in that it does not have the above-mentioned locking push button 4 and is used as a connecting tool used for jewelry such as a necklace. There was another problem that it was not practical in terms of functionality and design.

  Therefore, in recent years, it has been desired to improve the prior art disclosed in Patent Document 2 to assemble the components and form the connecting pin 5 without providing “caulking”.

  In order to solve the above-described problem, the jewelry accessory according to the present invention is an improvement over the jewelry accessory disclosed in FIGS. 3A and 3B related to Patent Document 2 described above. By using a V-shaped elastic part, the necessity of providing “caulking” is eliminated.

  That is, the accessory connector according to an embodiment of the present invention inserts the connecting pin 50 from the opening provided in the hollow connector body 20 and utilizes the elastic force of the connecting pin 50 to Provided is a jewelry connector 10 that is connected by being locked in a locking groove 26 of a connector body. More specifically, a hollow case 51 in which the connecting pin 50 abuts on the connector main body 20 and a V-shaped elastic part 57 are provided, and the bent portion 71 of the V-shaped elastic part is attached to the case 51. While pressing against the hollow bottom 515 of the case through the provided opening 53, the end 721 of one side surface 72 of the V-shaped elastic part is connected to the inner surface 511 of the opening 53 of the case 51 (for example, the inner portion of the opening). The connecting pin 50 is formed so that the other side surface portion 74 of the V-shaped elastic part can be swung by being fixed by a fixing portion 55 provided on the V-shaped elastic part.

In particular, one side surface 72 of the V-shaped elastic component 57 is brought into contact with the inner surface portion 511 of the case, and the length from the bent portion 71 to the end 721 of the one side surface 72 of the V-shaped elastic component 57 is increased. The V-shaped elastic part 57 is formed so as to be equal to the length from the hollow bottom 515 of the case to the fixing part 55 , and one side part 72 of the V-shaped elastic part 57 is fixed. .

  Further, a locking portion 58 is provided on the other side surface portion 74 of the V-shaped elastic part 57, and the locking portion 58 is provided inside the opening 24 of the connector main body 20. The connecting pin 50 is fixed at the time of connection to the connector main body 20 by being fitted to the connector body 20.

  Thus, it is possible to remove the necessity of providing a “caulking” and reduce the number of parts, that is, the connector for jewelry according to the present invention, that is, a connector that can be attached and detached with one touch by inserting a connecting pin into a hollow connector body. As a result, it is possible not only to manufacture a connecting device for jewelry that is smaller and lighter than the connecting device for accessories of the prior art, but also the connecting device for accessories manufactured in this way is low cost. It will be a thing.

  And the coupling tool for jewelry of such this invention improves the applicability to using as a fastener.
