Two joint surfaces having different surface areas are formed within the joint part of the grounding terminal, and the grounding terminal is soldered to the conductive pattern on the printed circuit board corresponding to the joint surfaces by using the solder having an amount corresponding to the surface area of each joint surface. Also, the bending area as the center of elastic deformation of the contact part of the grounding terminal is formed at a predetermined distance away from the relatively small joint surface of the joint part.
a joint part having a plurality of joint surfaces for soldering the grounding terminal to a conductive pattern on a printed circuit board; a contact part extending from and being connected to the joint part via a bending part, the contact part bending back over the joint surfaces and being configured to facilitate engagement with a grounding conductor, and the contact part being elastically deformable toward a rear surface of the joint surfaces upon engaging with a grounding conductor; and at least one of the joint surfaces of the joint part having a surface area which is smaller than a surface area of all remaining joint surfaces; wherein there is difference in hardening periods of solder applied to the joint surfaces between the smaller joint surface and the remaining joint surfaces of the joint part. 2. The grounding terminal according to claim 1, wherein the grounding terminal further comprises at least one intermediate part between the smaller surface and the remaining surfaces, the intermediate part is trapezoidal so that the intermediate part, once the contact part is deformed to a predetermined extent, contacts with the contact part to restrict further elastic deformation of the contact part.
The grounding terminal 10 in the embodiment is formed by bending a strip-like thin sheet metal member. The longitudinal center part of the metal member is a joint part 11, within which the metal member is bent such that the longitudinal section of the metal member forms a trapezoid, in other words, a groove 11 d is formed on one side of the joint part 11. Two surfaces oppositely positioned across the groove 11 d are joint surfaces 11 a and 11 b. In this case, the groove 11 d is formed at a predetermined distance away from the longitudinal center of the joint part 11, and thus one joint surface 11 a is smaller than the other joint surface 11 b. The metal member is bent in the upper direction at both ends of the joint part 11. At one end, the metal member is bent approximately perpendicularly to the joint part 11, and the bent part is further bent approximately perpendicularly so as to form a U-shaped longitudinal section with the joint part 11. Rectangular plate-like parts 14, which are bent perpendicularly in the direction of the joint part 11, are formed on both sides of the edge of the metal member. Also, projection parts 15 projecting from both sides of the metal member are formed at a predetermined distance away from the edge. The projection parts 15 are made by being separated from the neighboring member of the same shape when the strip-like thin sheet metal member is stamped out from a sheet metal
Also, in the mounting structure of the embodiment, the creamed solder 22 a and 22 b is applied to both of the two joint surfaces 11 a and 11 b formed within the joint part 11 of the grounding terminal 10. However, in order to prevent tombstone phenomenon, only the solder applied on the larger joint surface 11 b needs to be creamed solder 22 b. In other words, to prevent tombstone phenomenon, the adhesion on the larger joint surface 11 b is necessary to resist against the surface tension of the solder which is melted first on the smaller joint surface 11 a.
