Problems solved by technology

[0004] However, if Figure 10 In the illustrated engagement structure 800, when the engagement portion 830 is moved to achieve engagement, as Figure 11 As shown, in the cross-sectional view, it can be observed that the engaging protrusion 820 is locked on the linear portion L1 of the engaged portion 840 due to frictional resistance, resulting in a problem that the engagement is not achieved.

Deformed example 1

[0083] Next, use Figure 7 Modification 1 of the engaging structure 1 of the embodiment of the present invention will be described. Figure 7 It is an enlarged cross-sectional view of the periphery of the engagement structure 1 according to Modification 1 of the embodiment of the present invention.

[0084] The difference between the engagement structure 2 of Modification 1 and the engagement structure 1 of the embodiment is that it has an engagement protrusion 200 instead of the engagement protrusion 53 , and has an engaged portion 300 instead of the engaged portion 93 .

[0085] In addition, other structures are the same as those in the embodiment, and the same symbols are attached to the same structure as the embodiment.

[0086] When the engaging protrusion 200 and the engaged portion 300 are engaged with each other, the opposing surfaces 210, 310 that are engaged with each other are divided into two parts from the engaging protrusion in the direction perpendicular to the...

Deformed example 2）

[0089] Next, use Figure 8 Modification 2 of the engaging structure 1 of the embodiment of the present invention will be described. Figure 8 It is an enlarged cross-sectional view of the periphery of the engagement structure 3 according to Modification 2 of the embodiment of the present invention.

[0090] The engaging structure 3 of the modification 2 differs from the engaging structure 1 of the embodiment in that it has an engaging protrusion 400 instead of the engaging protrusion 53 , and has an engaged portion 500 instead of the engaged portion 93 .

[0091] In addition, other structures are the same as those in the embodiment, and the same symbols are attached to the same structure as the embodiment.

[0092] In the engaging protruding portion 400 and the engaged portion 500, each step surface 410, 510 forming a step difference between the two step surfaces 54a, 54b, 94a, 94b is from the lower step surface 54a, 94a toward the upper step surface. The stepped surfaces 54...

Deformed example 3）

[0095] Next, use Figure 9 Modification 3 of the engagement structure 1 of the embodiment of the present invention will be described. Figure 9 It is an enlarged cross-sectional view of the periphery of the engagement structure 4 according to Modification 3 of the embodiment of the present invention.

[0096] The difference between the engagement structure 4 of the modification 3 and the engagement structure 1 of the embodiment is that it has an engagement protrusion 600 instead of the engagement protrusion 53 , and has an engaged portion 700 instead of the engaged portion 93 .

[0097] In addition, other structures are the same as those in the embodiment, and the same symbols are attached to the same structure as the embodiment.

[0098] Of the engaging protrusion 600 and the engaged portion 700 , the swing front end 610 and the relative movement front end 710 are each formed in a tapering shape with a rounded tip.

[0099] The engaging structure 4 of the modified example 3...

Abstract

The invention relates to a clamping structure (1) which is not each to appear an unclamped phenomenon and can reduce the load needed by clamping. The clamping structure comprises: a clamping part (50) configured by a clamping protrusion part (53) formed on a side part (51a) a cantilever elastic sheet component (51); a paired clamping part (90) of a clamped part (93) clamped to the clamping protrusion part (53), wherein when the clamping part (50) is moved to clamp the clamping protrusion part (53) with the clamped part (93), the clamped part (93) is slidingly contacted with the clamping protrusion part (53) on a sliding contact surface, so as to make the cantilever elastic sheet component (51) swing from a neutral position by using a fixed end (51b) as a center, so as to make the clamping protrusion part be not contacted with the clamped part during elastic restoration of the cantilever elastic sheet component (51) to the neutral position, and so as to clamp the clamping protrusion part (53) with the clamped part (93) after the cantilever elastic sheet component (51) is elastically restored to the neutral position.

Description

technical field [0001] The present invention relates to an engaging structure, which has: an engaging portion formed by forming an engaging protrusion on one side of a cantilever elastic piece; The engaged portion that engages with each other. Background technique [0002] Conventionally, for example, as an engaging structure for connecting and fixing connectors respectively provided in an electronic control unit and an electrical junction box, there is an engaging structure in which an engaging protrusion is formed on one side of a cantilever elastic piece. part, and a mating engaging part having an engaged part that engages with the engaging protruding part (for example, refer to Patent Document 1). [0003] Such as Figure 10 As shown, such an engaging structure having an engaging portion formed by forming an engaging protrusion on one side of the cantilever elastic piece and a mating engaging portion having an engaged portion engaged with the engaging protrusion has : ...
