Press-fit fixing terminal, and electronic component having the same terminal

Abstract

A press-fit fixing terminal is mountable to a wiring board by being inserted into a through-hole of the wiring board, and includes a flat plate section and a resilient contacting section. The flat plate section is made of metal thin plate and double-backed such that an end of the flat plate section is placed on a root side and a bent point works as an insertion tip when the terminal is inserted into the through-hole. The resilient contacting sections sandwich the double-backed portion of the flat plate section such that they are placed symmetrically with respect to the double-backed portion and both of the ridges of the resilient contacting section face outward viewed from the double-backed portion, so that each one of the resilient contacting sections forms a V-shape including an obtuse angle.

Description

technical field [0001] The present invention relates to a press-fit fixing terminal inserted into a through hole of a wiring board for mechanical and electrical connection in order to mount various electronic components on the wiring board, and an electronic component having the press-fit fixing terminal. Background technique [0002] As a method of rationalizing the work of mounting various electronic components on wiring boards and as a method of replacing solder connection as part of the lead-free reduction of environmental loads, there is known a press-fit fixed terminal called press-fit. Methods. [0003] Such a conventional press-fit fixed terminal will be described with reference to FIGS. 6 to 8 . [0004] 6 is a front view of a conventional press-fit terminal, FIG. 7 is a side view of the press-fit terminal shown in FIG. 6, and FIG. 8 is a state where the press-fit terminal shown in FIG. 6 is mounted on a wiring board. Below is a schematic diagram of the section al...

Problems solved by technology

[0010] However, in the above-mentioned conventional press-fit fixed terminal 301, as shown in FIG. Billets of raw material will be contacted

Therefore, in order to ensure the stability of the electrical connection, it is necessary to perform plating treatment after the pressing process, and there is a problem that deformation or cost increase due to the operation of the plating treatment is likely to occur.
