Abstract:
1. An electronic device comprising: a substrate having a plurality of terminal lands disposed on a first surface of the substrate and a plurality of through holes in the substrate; an electric element including a plurality of terminals and a body, wherein each terminal is made of conductive material and is electrically coupled with a corresponding terminal land, and wherein the plurality of terminals are disposed on the body, and the body is arranged on the first surface of the substrate; and an auxiliary member configured to assist fixation between the electric element and the substrate, wherein a part of the auxiliary member is fixed to the body of the electric element, wherein the auxiliary member includes a base and a plurality of leg portions, wherein the base is fixed to the body of the electric element, wherein each leg portion extends from the base, and is inserted into a corresponding through hole, wherein the plurality of leg portions includes a pair of locking parts, each of which includes a latch and a spring, wherein the latch of each locking part is disposed on an insertion end of the leg portion, and is latched around the through hole on a second surface of the substrate, which is opposite to the first surface, wherein the spring is deformable when the latch is inserted into the through hole, wherein only one locking part is inserted into one through hole so that the pair of locking parts are inserted into two different through holes, respectively, wherein the substrate further includes a plurality of leg portion lands disposed on the first surface of the substrate, wherein at least a part of the plurality of leg portions is soldered on a corresponding leg portion land, wherein the leg portion land includes a surface land, wherein the at least a part of the plurality of leg portions includes a surface mounting structure and an insertion portion, wherein the surface mounting structure is soldered on a corresponding surface land, wherein the insertion portion is inserted into a corresponding through hole, wherein the surface mounting structure is disposed between the base and the insertion portion, wherein the surface mounting structure faces the corresponding surface land, wherein the leg portion land further includes an inner wall land, wherein the inner wall land is disposed on an inner wall of a corresponding through hole, wherein the inner wall land is soldered on the insertion portion of a corresponding leg portion, wherein the plurality of leg portions further include a bonding leg part, wherein the bonding leg part is different and separated from the pair of locking parts, and wherein the bonding leg part has an insertion end, which is disposed nearer the base in a thickness direction of the substrate than an insertion end of the locking part.
