[Problems to be solved by the device]

 In order to cover the upper opening of the case 1 with the cover 2, it is necessary to tilt the locking portion 3 b of the stopper 3 to the outside of the case 1. However, the attachment structure of the stopper 3 and the case 1 does not include a biasing means for holding the stopper 3 in the outwardly tilted state. Therefore, as shown in FIG. 6, the stopper 3 may rotate before the cover 2 is placed on the case 1 so that the locking portion 3b is located above the opening of the case. Even if the cover 2 is covered in this state, the stopper 3 is sandwiched between the case 1 and the cover 2, and the cover 2 cannot be covered. Therefore, in order to cover the cover 2, an extra work of temporarily tilting the locking portion 3b of the stopper 3 to the outside of the case 1 must be performed, which causes a problem of poor workability.

The present invention has been made in view of the above problems, and provides an attachment structure for a buckle type fastener that improves workability by improving the attachment structure for a buckle type fastener and a case. It is a thing.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. As shown in FIGS. 1 to 3, in the present invention, a buckle type stopper 10 formed by bending a leaf spring shown in FIG. 2 is used, and a case 11 such as an electric junction box requiring waterproofness is provided. The cover 12 and the cover 12 are engaged in a sealed state.

The stopper 10 is formed by bending a rectangular substrate 10a in the lengthwise direction so as to have a spring property, and has a substantially J-shaped attachment in which one end of the substrate 10a is bent inward in the bending direction. A portion 10b is provided. In the mounting portion 10b, the board 10a side serves as a connecting portion 10c, and the tip of the mounting portion 10b protruding in a direction substantially orthogonal to the board 10a serves as a locking plate portion 10d. It is press-fitted into the mounting hole 11a, and the tip of the locking plate portion 10d is locked to the stepped portion 11b projecting radially inside the mounting hole 11a. It can be rocked. In addition, the mounting portion 10b is provided with a cutout portion 10e extending in the lengthwise direction from the vicinity of the base point of the base plate 10a to the tip of the locking plate portion 10d and extending in the central portion in the longitudinal direction.

The other end of the substrate 10 a is bent in the same direction as the mounting portion 10 b and has a substantially L-shaped engagement with which the engagement recess 12 a formed on the cover 12 is fitted and locked. A stop portion 10f is provided, and the side continuous with the substrate 10a is the engagement plate portion 10g, and the other side is the operation portion 10h. In addition, the tip portion of the operating portion 10h is folded back to provide a curved portion 10i to protect an operator who holds the operating portion 10h.

At a position near the mounting portion 10b side between the mounting portions 10b and the locking portions 10f at the both ends, the center in the width direction is cut and raised in the lengthwise direction, and protrudes in the same direction as the mounting portion 10b. A projecting portion 10j having a continuous end 10j-1 on the locking portion 10f side is provided.

The case 11 is provided with a protrusion 11c that abuts the protrusion 10j of the stopper 10 so as to protrude outward. More specifically, the protrusion 11c is a horizontal surface 11c-1 protruding outward in the horizontal direction from a fitting surface 11d of the case 11 with the cover 12, and an outer wall 11f of a mounting portion 11e having the mounting hole 11a. Further, it has a triangular cross-section with a tapered surface 11c-2 that is inclined upward toward the tip of the horizontal surface 11c-1.

The projection 11c has a tapered surface 11c-2 in an open state in which the stopper 10 is tilted to the outside of the case 11 to bring the connecting portion 10c into contact with the inner peripheral wall of the mounting hole 11a facing the stepped portion 11b. The free end 10j-2 of the protruding portion 10j is set to abut on the lower end portion of the. Further, in the closed state in which the locking portion 10f of the stopper 10 is engaged with the locking recess 12a of the cover 12 that is placed on the upper surface of the case 11, the protruding portion of the stopper 10 is attached to the tip of the horizontal surface 11c-1 of the protrusion 11c. It is set so that the vicinity of the free end 10j-2 of 10j abuts.

As described above, the stopper 10 attached to the case 11 has the free end of the projecting portion 10j in contact with the lower end portion of the tapered surface 11c-2 of the case 11, so that the stopper portion on the tip side is engaged. The 10f side is urged in a direction to open to the outside, and the stopper 10 is held in an open position that is not located above the case 11. Therefore, as shown in FIG. 3, the stopper 10 does not hinder the covering work of the cover 12 from above the case 11, and the covering work of the cover 12 can be easily performed with good workability.

As described above, after covering the upper surface of the case 11 with the cover 12, the operating portion 10h of the stopper 10 is gripped and rotated in the closing direction. By this rotation of the stopper 10, the free end of the protruding portion 10j moves while sliding along the tapered surface 11c-2. In addition, since the stopper 10 is formed of the leaf spring, this rotation work can be easily performed because the protrusion 10j is curved.

The stopper 10 is further rotated around the mounting portion 10b as a fulcrum, and the locking portion 10f is fitted and locked in the locking recess 12a of the cover 12, so that the case 11 and the cover 12 are sealed. State. In this engaged state, the engaging plate portion 10g of the stopper 10 is in surface contact with the engaging recess 12a of the cover 12, so that a reliable engaged state can be maintained.

FIG. 4 shows a modified example of the buckle type stopper, in which the stopper 10 ′ is cut and raised on both sides in the width direction of the substrate 10 a, and two projecting portions 10 j ′ and j ′ are arranged side by side. ing.
