The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: illustrated in Fig. 3 and Fig. 4, being combined with has most installing holes 40 on the substrate 2 of installed part 1.Installing hole 40 is the back parts to flange 52 that are used for inserting installed part 1.
And, on the installing hole 40 of substrate 2, forming the flange 42 that is connecting with the one side, flange 42 is to form from inboard prolongation the in the lateral of installing hole 40, is positioned at same plane with substrate 2.
Existing flange 14 rearward prolongs and forms, relatively under, flange 42 of the present invention is to prolong formation to the inside in order to be positioned at same plane with substrate 2.
And, on the anterior locations of flange 42, form the mounting boss 44 of projection.Form crank slot 46 at the back of flange 42 mid portion.Mounting boss 44 is the lug bosses that form in order to fixedly mount part.Free end 43 bending rearward in order to make flange 42 of the present invention along the whole width of flange, forms crank slot 46 in the back of flange 42.Therefore, in the time of the free end 43 that rearward pushes away flange 42, the free end 43 of crank slot 46 inboards can be rearward crooked.
And the installed part 1 that will install on substrate 2 and substrate recited above 2 are made by injection mo(u)lding.Installed part 1 is exactly the various parts that representative constitutes the injection mo(u)lding in the middle of the parts of micro-wave oven.Such installed part 1 will be installed in most installing holes 40 on the substrate 2, therefore, can be maintained fixed state.
