PROBLEM TO BE SOLVED: To suppress a conduction defect at the contact point of a conductive pattern to electrically contact to another member, in a structure having the conductive pattern formed on a first resin layer and a second resin layer molded thereon.SOLUTION: A first resin layer (1) includes a covered area covered with a second resin layer (2) and an exposed area (1a). A contact point part (1b) is disposed on the exposed area (1a). Further, a bent part (1c) is disposed between the boundary of the covered area and the exposed area (1a) and the contact point part (1b).

PROBLEM TO BE SOLVED: To prevent exfoliation between the boundary surfaces of a conductive pattern and a second resin layer in a structure having the second resin layer molded on a first resin layer having the formed conductive pattern.SOLUTION: A step difference part (5) is provided on a first resin layer (3) along the shape of at least a part of a conduction pattern (2). The first resin layer (3) closely adheres to a second resin layer (4) at the step difference part (5).
Abstract:
PROBLEM TO BE SOLVED: To provide a strain tolerance electrical connection structure, and to provide a forming method of the same.SOLUTION: Wire and other conductive lead wires 30 are connected to an electric circuit 40 in a manner as forming a connection superior in tolerance for mechanical stresses, such as movement or rotation of the lead wire 30 with respect to the electric circuit 40. A material for generating an area which reduces the deflection property or improves the rigidity near a connecting point is formed around the lead wire 30 and near the connecting point to the electric circuit 40. The lead wire can be formed into a coil shape or into a shape which gives the capability of enduring the mechanical stresses.
Abstract:
PROBLEM TO BE SOLVED: To provide a connecting element capable of automatic mounting by using a suction nozzle without changing product characteristics and suitably securing a stroke. SOLUTION: An elastic contact section 3 pressed against a grounding conductor by deforming elastically is connected with one end 2B of a solder-connecting section 2 of the connecting element 1 where a lower surface 2A is to be a solder joint surface. A rectangular hole 3C is formed between a folded section 3A and a tip 3B of the elastic contact section 3. A suction section 4 is connected to the other end 2C of the solder-connecting section 2, and the tip 4B of the suction section 4 is bent in a direction parallel to the solder-connecting section 2, and exposed at an upper surface side of the elastic contact section 3 by penetrating the hole 3C of the elastic contact section 3. The elastic contact section 3 can be restrained from generating distortion even if the suction nozzle is pushed to an upper surface of the suction section 4 since the tip 4B of the suction section 4 is sucked with the suction nozzle of an automatic mounting machine, and product characteristics of the connecting element 1 can be stably maintained.
