Now, the reverse side (elasticity snap-latch piece 24 side) of elasticity snap-latch piece 24 side of the close connector 2 of abutting part 55 becomes the part of the abutting part 53A abutted for elasticity snap-latch piece 24.Therefore, abutting part 53A, 55 is because abutting for connector 2, key 4 and require larger intensity.Thus, in the present embodiment, it is asymmetrical irregularly shaped by the outer shape on elasticity snap-latch piece 24 top is set to the left and right being provided with sloping edge 24C, thickness between abutting part 53A, 55 is set to corresponding enough size irregularly shaped with this, thus guarantees the intensity between abutting part 53A, 55.
Along with key 4 rotates clockwise, the square hole portion 36B of keyhole 36 and being communicated with through space in the rotary motion trace of 45 processes in press section, key side.The press surface 28A being located at press section, snap-latch piece side 28 of connector 2 is positioned at one of them through space, key 4 rotates at the beginning, the inclined plane 45A of press section, a key side 45 contacts with the top edge of press section, snap-latch piece side 28, rides over afterwards press surface 28A presses elasticity snap-latch piece 24 to make it be out of shape.The part of the inwall in another space becomes the abutting part 56 that another press section 45, key side for key 4 abuts, and the rotational angle of key 4 is defined as 90 °.
In keyhole 36, the center O2 of keyhole 36 becomes corresponding with the center of rotation O1 of key 4 coaxial, the right side that center O2 is partial in Fig. 3 for benchmark with the center line C1 of connector 2 and the common width of socket 3.Utilize this structure, establishing in the present embodiment in left side in figure 3 with the press section, key side 45 that contacts, engaging press section, side 28 for each center O1, O2, when making key 4 rotate, press section, key side 45 can be made to start to contact with press section, snap-latch piece side 28 in the position close to center line C1.Therefore, when utilizing press section, key side 45 to press elasticity snap-latch piece 24, transmitting the pressing force come from press section 45, key side acts near the center line C1 of the width of elasticity snap-latch piece 24, elasticity snap-latch piece 24 can be prevented to be pressed under departing from larger state relative to center line C1, can reliably to carry out the releasing of fastening state and the projecting motion of connector.
But the contact position in fact, between press section, key side 45 and elasticity snap-latch piece 24 is partial to the left side in Fig. 3 to a certain extent relative to center line C1.Thus, key 4 start rotate and by press section, key side 45 in the present embodiment pressing elasticity snap-latch piece 24, the deformation state of elasticity snap-latch piece 24 likely produces deflection.That is, can think, across center line C1 and O1, O2 opposite sides, each center, elastic deformation is larger.
Therefore, in the present embodiment, the mode that the engaging recessed part 27 of connector 2 and the engaging protuberance 37 of socket 3 are partial to left side with the center C2 of the two width relative to the center line C1 of entirety is arranged, even if when elasticity snap-latch piece 24 elastic deformation on the bias, also can the fastening state of engagement release recess 287 and engaging teat 37 more reliably.
Below, the action of bracelet 1 is described according to Fig. 4 ~ Fig. 7.
First, as shown in Figure 4, when inserting connector 2 in socket 3, along with the carrying out inserted, the elasticity snap-latch piece 24 of connector 2 contacts with the engaging protuberance 37 of socket 3, and elasticity snap-latch piece 24 passes through engaging protuberance 37 while being pressed to Figure below.When the holding section 27B of the engaging recessed part 27 being located at elasticity snap-latch piece 24 passes through the holding section 37B of engaging protuberance 37, the elastic deformation of elasticity snap-latch piece 24 recovers, and holding section 27B, 37B engage mutually.This state is the state that connector 2 and socket 3 have engaged.
Under this fastening state, owing to cannot utilize the pressing elasticity snap-latch pieces 24 such as manual operation from outside, therefore, the engaging between connector 2 and socket 3 cannot be removed, connector 2 cannot be extracted from socket 3.That is, when connector 2 and socket 3 become fastening state, connector 2 is locked in socket 3 by key, does not need the key lock operation carrying out using key 4 after engaging.
Then, when remove locking, engagement release and connector 2 is extracted from socket 3, as shown in Figure 4, key 4 is inserted in keyhole 36, as shown in Figure 5, rotates clockwise key 4.So when starting to rotate, the inclined plane 45A being located at press section, key side 45 contacts with the top edge of press section, snap-latch piece side 28, rides on press surface 28A and is pressed downwards by elasticity snap-latch piece 24.Elasticity snap-latch piece 24 elastic deformation be pressed, in the starting stage of the rotating operation of key 4, engaging recessed part 27 departs from from engaging protuberance 37, and engaging is each other removed.
And then as shown in Figure 6, when the rotating operation of key 4 proceeds to predetermined angular, in during till this predetermined angular of arrival, elasticity snap-latch piece 24 is connected to the reverse side wall 32 of socket 3, and its elastic deformation is prevented from (Fig. 7).On the other hand, along with the rotation of key 4, the press surface 28A of the inclination of press section, key side 45 and connector 2 still rubs mutually, and therefore, as shown in figure hollow core arrow, press surface 28A is subject to the pressing force towards the direction released by connector 2.
Its result, as shown in Figure 7, connector 2 is pushed out into the precalculated position being easy to hold.Connector 2 can be extracted afterwards.As mentioned above, by inserting key 4 and making it rotate, the lockup state between connector 2 and socket 3 can not only be removed, the state that the two engages mutually can also be removed, and action connector 2 being released scheduled volume can be carried out.
Adopt above present embodiment, following effect can be obtained.
That is, bracelet 1 is formed by these 3 parts of connector 2, socket 3 and key 4, therefore, it is possible to save in the past such rotor, lock cover or the such parts of pivoted arm, can slimming be promoted.
In buckle in 1, the snap-action carried out due to connector 2 is inserted into socket 3 directly becomes locking operation, therefore, it is possible to key operated when saving locking.In addition, the locking carried out owing to using key 4 removes the operation directly becoming engaging and remove, and therefore, again need not carry out the operation for engagement release after locking is removed.Thereby, it is possible to significantly improve the operability of bracelet 1.
In buckle in 1, owing to being not only, key 4 is inserted into keyhole 36, or makes the rotation of this key 4 can carry out locking releasing and engaging releasing, therefore, also be difficult to remove even if the parts of non-dedicated key are inserted into keyhole to carry out to remove, security can be made good.
And, although need the press section, key side 45 making key 4 to climb up press section, snap-latch piece side 28 when utilizing key operated releasing, but because press section, key side 45 is provided with inclined plane 45A, this inclined plane 45A contacts with the ora terminalis of press section, snap-latch piece side 28, therefore, press section, key side 45 successfully can be made to climb up press surface 28A along with the rotation of key 4, the operability of key 4 can be improved.
In buckle in 1, tilt by making the press surface 28A of press section, snap-latch piece side 28, thus press section, key side 45 is out of shape to make elasticity snap-latch piece 24 along with the rotation of key 4 does not only press press surface 28A, also towards the extracting direction pressing of connector 2, elasticity snap-latch piece 24 is out of shape press surface 28A, therefore, connector 2 locking remove and engaging remove basis on, connector 2 can also be released scheduled volume relative to socket 3, the connector 2 after can making it extract processing ease.
In buckle in 1, because the center line C1 of the width of both the center of rotation O1 of key 4 and connector 2 and socket 3 staggers, press section, key side 45 contacts with elasticity snap-latch piece 24 in the position near center line C1, therefore, the distortion of the deflection of elasticity snap-latch piece 24 can be prevented, the engaging between the engaging recessed part 27 of connector 2 side and the engaging protuberance 37 of socket 3 side can be removed more reliably.
