Abstract

A connector terminal suitable for a case where the operation height is relatively low and the strength is relatively large is provided. A connector terminal includes a strip-like solder plate, and one end of the solder plate is bent upward in an arc shape to form a bent portion, and the end of the bent portion is inclined with respect to the solder plate. The elastic arm 30 is formed by bending upward and extending, and the elastic arm has an arc shape protruding downward, and the end of the elastic arm is bent and extended to form the contact portion 40. In the operation process, the elastic arm and the solder plate gradually change from point contact to surface contact in the operation process, and the acting force is distributed to the arc-shaped bent portion 20 and the elastic arm 30, thereby increasing the pressure resistance. Suitable for low operating height and relatively high strength requirements. [Selection] Figure 3

Description

  The present invention relates to a kind of connector, and more particularly to a kind of connector terminal.

  FIG. 1 shows a known connector terminal 100 '. The connector terminal 100 ′ has a strip-shaped solder plate 10 ′. One end of the solder plate 10 ′ is bent upward in an arc shape to form a bent portion 20 ′, and the bent portion 20 ′ is a lateral U-shape. Presents. The end of the bent portion 20 ′ is extended obliquely upward with respect to the solder plate 10 ′ to form an elastic arm 30 ′, and the end of the elastic arm 30 ′ is subsequently extended to form a connecting portion 40 ′. The end of 40 'is bent upward to form a semicircular shape, and further bent and stretched in the direction of elastic arm 30' to form contact portion 50 '.

  The known design of the connector terminal 100 ′ described above is such that when the reaction force is repeatedly applied to the contact portion 50 ′, the connector terminal 100 ′ is deformed in the vicinity of the U-shaped bent portion 20 ′ as shown in FIG. It is not suitable when it is likely to occur, the operating height is relatively low, and the strength requirements are high.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a connector terminal suitable for an operation scene having a relatively low operation height and a relatively high strength, in response to the above-mentioned lack of the known technology.

  In order to achieve the above object, a connector terminal provided by the present invention includes a strip-shaped solder plate, and one end of the solder plate is bent upward in an arc shape to form a bent portion. The end is bent and extended obliquely upward with respect to the solder plate to form an elastic arm, the elastic arm has an arc shape protruding downward, and the end of the elastic arm is bent and extended to form a contact portion. Is done.

  As described above, in the connector terminal of the present invention, in the operation process, the elastic arm and the solder plate gradually change from point contact to surface contact, and the acting force is distributed to the arc-shaped bent portion and the elastic arm. This is suitable when the pressure resistance is large, the operation height is low, and the strength requirement is relatively large.

It is a three-dimensional view of a known connector terminal. FIG. 2 is a state display diagram in which deformation has occurred in the connector terminal of FIG. 1. It is a three-dimensional view of the connector terminal of the present invention. FIG. 4 is a state display diagram in which deformation has occurred in the connector terminal of FIG. 3.

  In order to describe in detail the technical contents, structural features, and objects to be achieved of the present invention, examples will be described below in combination with the drawings.

  Please refer to FIG. The connector terminal 100 of the present invention includes a strip-shaped solder plate 10, and one end of the solder plate 10 is bent upward in an arc shape and further bent downward in an arc shape to form a bent portion 20. The end of the portion 20 is bent and stretched in an arc shape obliquely upward with respect to the solder plate 10 to form an elastic arm 30, and the elastic arm 30 has an arc shape protruding toward the solder plate 10, The end of the elastic arm 30 is bent and stretched to form the contact portion 40.

  When the opening 11 is opened in the middle part near the other end of the above-described solder plate 10, the kerf 12 is opened on both sides of the substantially middle part of the solder plate 10, and the opening 11 and the kerf 12 are soldered to the solder plate 10. The purpose is to collect the solder liquid and prevent the solder from spreading on the connector terminal 100. The contact portion 40 is provided with a strip-shaped convex hull 41 and can contact the corresponding connection element.

  Please refer to FIG. When the solder plate 10 of the connector terminal 100 of the present invention is soldered to the circuit board and the convex hull 41 is subjected to the downward pressing force by other elements to which the convex hull 41 is correspondingly connected, the elastic arm 30 generates elastic deformation. The contact area between the elastic arm 30 and the solder plate 10 is increased.

  As described above, in the connector terminal 100 of the present invention, the elastic arm 30 and the solder plate 10 gradually change from point contact to surface contact in the operation process, and the acting force is changed to the arc-shaped bent portion 20 and the elastic arm. 30, which is suitable for cases where the compressive strength is high, the operating height is low and the strength requirements are relatively high.
