Problems solved by technology

[0007] The conventional press-fit type connector terminals proposed in the above-mentioned Japanese Patent Application Publication Nos. 2004-134275 and 2007-157469 are difficult to allow a large amount of current to flow therethrough.
In addition, because the above-mentioned conventional press-fit type connector terminal is designed to have an outer diameter larger than the inner diameter of the through-hole of the printed circuit board, and is connected with the through-hole by inserting a press-fit portion having low elasticity into the through-hole. Electrical contact, resulting in the following problems: the printed circuit board is whitened due to the contact pressure exerted by the press-fit part on the through-hole, and the metal plated on the inner surface of the through-hole is peeled off
However, since each sub-terminal to be inserted into a through-hole of a printed circuit board is in the shape of an eye of a needle, the press-fit type connector terminal cannot absorb dimensional tolerances caused between the through-hole and each sub-terminal, resulting in deterioration of contact reliability. deterioration

[0079] The following reference figure 1 To 8 illustrate the press-fit type connector terminal 100 according to the first embodiment of the present invention.

[0080] Such as Figure 1 to 5 As shown, by bending a single metal plate 110 with elasticity (see Figure 8A with 8B ) To form a press-fit connector terminal 100.

[0081] The press-fit type connector terminal 100 includes a pin portion 111 having a flat plate shape, a plurality of contact portions 113 continuous with the front end of the pin portion 111, and a flat shoulder 112 between the front end of the pin portion 111 and the contact portion 113 .

[0082] Each of the contact portions 113 includes a plurality of " The contact piece 13 in the shape of "<" extends along the imaginary centerline 113c and protrudes outward to surround the imaginary centerline 113c.

[0083] The inner shaft portion 114 continuous with the contact piece 13 is erected coaxially with the imaginary center line 113 c in each of the contact portions 1...

[0105] Figure 13 to 1 The press-fit type connector terminal 300 according to the third embodiment shown in 7 is designed to include a shoulder 312 having a double-wall structure. Specifically, such as Figure 17A with 17B As shown, the metal plate 310 forming the press-fit type connector terminal 300 is designed to include the width direction of the pin portion 111 (see Figure 13 ) A strip-shaped fourth area 321 extending in parallel, the fourth area 321 is located between the first area 120 for forming the pin portion 111 and the sixth area 122 for forming the connecting portion 119 each. The shoulder 312 is formed by folding the fourth region 321 along two folding lines 329 extending parallel to the folding line 128. The two regions that extend outwardly beyond the fold line 329 define opposite ends 312 a of the shoulder 312. The opposite ends 312 a of the shoulder 312 protrude from the contact portions 113 at the left and right ends among the contact portions 113 arranged ...

Abstract

The press-fit type connector terminal includes a pin section in the form of a flat plate, and a plurality of contact sections situated continuous to a front end of the pin section, each of the contact sections including a contact piece being in the form of a barrel or a spindle surrounding an imaginary center line, the contact piece being formed with a slit extending substantially parallel to the imaginary center line, the connector terminal being comprised of a single bent metal plate having elasticity.

Description

Technical field [0001] The present invention relates to a press-fit type connector terminal to be inserted into a conductive through hole formed through a printed circuit board. Background technique [0002] Various press-fit type connector terminals have been proposed. For example, they have a terminal contact portion with a pin eye, C-shaped, N-shaped or Σ-shaped cross section. [0003] Japanese Patent Application Publication No. 2004-134275 has proposed a press-fit type connection terminal that includes a head to which a cable is connected and a body to be inserted into a through hole formed through a substrate. The main body is formed with a hole extending in its length direction at the center, and the main body is formed with a plurality of slits extending from an inner wall of the main body to an outer wall. The hole is filled with conductive adhesive. [0004] Japanese Patent Application Publication No. 2007-157469 has proposed a press-fit type terminal including a press-fi...
