Problems solved by technology

[0008] In the crimp connector described in Patent Document 1, the first spring part and the second spring part are bent independently of each other from the lower flat plate part, so it is difficult to ensure high precision due to springback after deformation of each spring part. The relative position of the upper side flat part and the auxiliary upper side flat part
Therefore, variations in the size of the helical structure are likely to occur, and it is difficult to minimize the variation in elastic resilience during compression for each crimp connector.
In addition, since the first spring part and the second spring part do not constrain each other, there is a possibility that the crimp connector may be inappropriately acted accidentally during the process of storing the crimp connector or in the process of mounting the crimp connector to an electronic device or the like. When an external force is applied, there is a possibility of deformation such as opening of each spring part

Abstract

The present invention provides a crimp connector capable of stabilizing the dimensional accuracy of a spiral structure portion composed of two spiral portions and also improving the strength of the spiral structure portion, and a method of manufacturing the same. The spiral structure portion is formed by a conductive plate material. The spiral structure portion has a first spiral portion (10) anda second spiral portion (20). A contact portion (18) is formed at a front portion of the first spiral portion (10), and a support portion (28) opposed to the contact portion (18) from the base portionside is formed at a front portion of the second spiral portion (20). By welding and fixing the contact portion (18) and the support portion (28), the first spiral portion (10) and the second spiral portion (20) can be connected to each other with a high relative position.

Description

Technical field [0001] The present invention relates to a crimp connector with a spiral structure formed of a conductive plate material, and more particularly to a crimp connector with a structure capable of exerting stable elastic resilience and easily preventing deformation of the spiral structure, and a manufacturing method thereof. Background technique [0002] Patent Document 1 describes a crimp connector formed of a conductive plate material. [0003] The crimp connector has a lower flat plate part, an upper flat plate part, and an auxiliary upper flat plate part located on the lower side of the upper flat plate part. A first spring part is provided between the lower flat plate part and the upper flat plate part, and a second spring part is provided between the lower flat plate part and the auxiliary upper flat plate part. Both the first spring portion and the second spring portion are bent so as to stand up from the lower flat portion to form a spiral shape, and the plate s...
