An electronic component protecting cover includes a fixed cover portion, a hinge portion, and a rotatable cover portion. One of the fixed cover portion and the rotatable cover portion has engaging portions at two locations, and the other of the fixed cover portion and the rotatable cover portion has catching portions at two locations, the engaging portions and the catching portions being configured to be engaged with each other. Each of the engaging portions has a pair of locking tabs, and each of the catching portions has a pair of locking frames. Because each of the engaging portions and each of the catching portions has double-locking structure, sufficient locking force can be provided. |

1. An electronic component protecting cover comprising a fixed cover portion configured to be mounted on an electronic component in a fixed manner, a hinge portion, and a rotatable cover portion connected to the fixed cover portion via the hinge portion such that the rotatable cover portion is operable to be opened and closed around an axis of the hinge portion as a rotation center,
wherein one of the fixed cover portion and the rotatable cover portion has engaging portions at two locations along an axial direction of the hinge portion, and the other of the fixed cover portion and the rotatable cover portion has catching portions at two locations along the axial direction of the hinge portion, the engaging portions and the catching portions being configured such that, when the rotatable cover portion is moved to an open position, the engaging portions and the catching portions are engaged with each other to hold the rotatable cover portion at the open position, wherein each of the engaging portions has a pair of rib-shaped locking tabs disposed so as to be separated from each other in the axial direction of the hinge portion and parallel to each other, the locking tabs are configured to deflect in the axial direction of the hinge portion during the engagement of the engaging portions and the catching portions, and the locking tabs has locking protrusions protruding outwardly from outside faces of the locking tabs or inwardly from inside faces of the locking tabs bilaterally symmetrically with respect to a center line between the locking tabs, wherein each of the catching portions has a pair of locking frames disposed so as to be separated from each other in the axial direction of the hinge portion and parallel to each other, the locking frames are configured to be engaged with the locking protrusions of the pair of locking tabs through the deflection of the locking tabs, and the locking frames has locking edges configured to be engaged with the locking protrusions, the locking edges being provided inwardly or outwardly on sides on which the locking protrusions of the corresponding locking tabs are provided, and wherein a distance between the pair of locking tabs is smaller than a distance between one of the locking tabs of one of the engaging portions and located on a side of the other of the engaging portions and one of the locking tabs of the other of the engaging portions located on a side of the one of the engaging portions. |
