Abstract
Official abstract text for this publication.
A dissimilar material joint including a joined portion between a resin rib and a metal base, in which the metal base forms a protrusion protruding inside of the resin rib on at least a part of the joined portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dissimilar material joint comprising a resin rib and a metal base, the metal base includes (a) a first portion, (b) a second portion and a protruded portion between the first portion and the second portion, the protruded portion is formed by bending a portion of the metal base with respect to the first portion and the second portion, the protruded portion protrudes into the resin rib disposed on the protruded portion, wherein at least part of the first portion and at least part of the second portion is not covered by the resin rib, a surface of the protruded portion of the metal base comprises protrusions and a resin of the resin rib intrudes into the protrusions on the surface of the protruded portion of the metal base, and, wherein the protruded portion comprises a groove that extends continuously in a longitudinal direction of the resin rib. 2. The dissimilar material joint according to claim 1 , wherein the metal base has a first surface and a second surface opposite to the first surface, the resin rib is disposed on one of the first surface and the second surface of the metal base of the metal base, and the protruded portion includes a single groove having an inverted V-shaped cross section. 3. The dissimilar material joint according to claim 1 , wherein the metal base has a first surface and a second surface opposite to the first surface, and a first resin rib is disposed on the first surface of the metal base in the protruded portion and a second resin rib disposed on the second surface of the metal base in the protruded section. 4. The dissimilar material joint according to claim 1 , wherein the protruded portion includes two grooves parallel to each other and having an inverted V-shaped cross section and a V-shaped cross section, respectively. 5. The dissimilar material joint according to claim 1 , wherein a metal constituting the metal base is one or two or more selected from iron, stainless steel, an aluminum alloy, a magnesium alloy, and a copper alloy. 6. The dissimilar material joint according to claim 1 , wherein the resin rib is formed of a thermoplastic resin composition containing a thermoplastic resin and a filler. 7. The dissimilar material joint according to claim 6 , wherein the resin rib is formed by injection molding of the thermoplastic resin composition onto the metal base. 8. The dissimilar material joint according to claim 1 , in which the dissimilar material joint has a developed planar structure in which a housing for accommodating electronic components is developed. 9. A housing for accommodating electronic components comprising the dissimilar material joint according to claim 1 . 10. The dissimilar material joint according to claim 1 , wherein the first portion and the second portion are edge portions of the metal base. 11. The dissimilar material joint according to claim 1 , wherein the metal base consists of the first portion, the second portion and the protruded portion. 12. The dissimilar material joint according to claim 1 , wherein the protrusions have an interval period from 5 nm to 500 μm.
