Abstract

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.

First claim

What is claimed is:

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.

2 . The electronic component protecting cover according to claim 1 , wherein the locking protrusions are outwardly protruded from the outside faces of the locking tabs bilaterally symmetrically with respect to the center line between the locking tabs, and
wherein at two points on the pair of locking tabs where the pair of locking tabs becomes closest to each other during the deflection, a distance between the pair of locking tabs in a state in which the pair of locking tabs are deflected is larger than a sum of protrusion heights of the locking protrusions of the locking tabs.

3 . The electronic component protecting cover according to claim 2 , wherein at the two points where the pair of locking tabs becomes closest to each other during the deflection, the distance between the pair of locking tabs in the state in which the pair of locking tabs are not deflected is slightly larger than the sum of the protrusion heights of the respective locking protrusions of the locking tabs.

4 . The electronic component protecting cover according to claim 2 , wherein the locking edges of the locking frames configured to be engaged with the locking protrusions are formed inwardly on the sides on which the locking protrusions of the corresponding locking tabs are provided, and the locking frames have recesses opposed to each other in the axial direction of the hinge portion such that each of each of the locking frames has a bottomed cylindrical shape, and the locking edges are configured as edges of peripheral walls of the recesses.

5 . The electronic component protecting cover according to claim 2 , wherein each of the locking frames is configured as a locking hole, and the hole edge sections of the locking hole provided on the sides on which the locking protrusions of the corresponding locking tabs are provided are configured as the locking edges.

6 . The electronic component protecting cover according to claim 1 , wherein the engaging portions and the catching portions are disposed on outer sides of respective ends of the hinge portion in the axial direction.

7 . 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 an engaging portion, and the other of the fixed cover portion and the rotatable cover portion has a catching portion, the engaging portion and the catching portion being configured such that, when the rotatable cover portion is moved to an open position, the engaging portion and the catching portion are engaged with each other to hold the rotatable cover portion at the open position, wherein the engaging portion has a locking tab formed so as to be perpendicular to an axial direction of the hinge portion, the locking tab is configured to deflect in the axial direction of the hinge portion during the engagement between the engaging portion and the catching portion, and the locking tab has a locking protrusion protruding outwardly from an outside face of the locking tab or inwardly from an inside face of the locking tab, wherein the catching portion has a locking frame configured to be engaged with the locking protrusion of the locking tab through the deflection of the locking tab, and the locking frame has a locking edge configured to be engaged with the locking protrusion, the locking edge being provided inwardly or outwardly on a side on which the locking protrusion of the locking tab is provided, and wherein the locking protrusion has a front side face configured as an upward sloping face that makes slide contact with the locking edge to gradually deflect the locking tab when the rotatable cover portion is first moved toward the open position, a rear side face configured as a downward sloping face that makes slide contact with the locking edge after locking tab slides over the upward sloping face through the deflection of the locking tab and allows the locking tab to gradually return from the deflected state to generate an engagement force between the locking tab and the locking edge, the downward sloping face being steeper than the upward sloping face, and a intermediate section extending from the upward sloping face to the downward sloping face and having a curved or flat surface, the intermediate section located inside an outer peripheral face of the locking protrusion if the locking protrusion is formed to have a hemispherical shape.

8 . The electronic component protecting cover according to claim 7 , wherein the downward sloping face coincides with a portion of the outer peripheral face of the locking protrusion if the locking protrusion is formed to have the hemispherical shape.

9 . The electronic component protecting cover according to claim 7 , wherein a diameter of the hemispherical shape is a distance between a lower end of the upward sloping face and a lower end of the downward sloping face.

10 . The electronic component protecting cover according to claim 7
