  However, the conductive terminal disclosed in Patent Document 1 has a complicated structure, which is disadvantageous for miniaturization of the electrical connector. Moreover, since the base part for hold | maintaining a conductive terminal increases, there existed a problem that manufacturing cost became high. Therefore, it is necessary to develop a new conductive terminal and an electrical connector using the same.

  An object of the present invention is to provide a conductive terminal having a simple structure and an excellent elastic deformation capability, and an electrical connector using the same.

  The conductive terminal of the present invention includes a base, an elastic arm extending upward from one side of the base, a solder tail extending from the other side of the base, and outward from the end of the elastic arm. In the conductive terminal including a contact arm extending in a tapered manner, the elastic arm and the base are flush with each other, and the elastic arm extends in a wavy manner.

  The electrical connector of the present invention is an electrical connector including an insulating housing in which a plurality of terminal accommodating passages are formed, and a plurality of conductive terminals accommodated corresponding to the terminal accommodating passages, wherein the conductive terminals are: A base, an elastic arm extending upward from one side of the base, a solder tail extending from the other side of the base, and a contact tapering outward from the end of the elastic arm And an elastic arm and a base of the conductive terminal are flush with each other, and the elastic arm extends in a wavy manner.

  Compared with the prior art, the electrical connector of the present invention has the advantage that the elastic arm of the conductive terminal extends in a wavy manner, so that the length of the elastic arm is increased and has an excellent elastic deformation capability. Yes.

It is an assembly perspective view of each terminal accommodation passage and a conductive terminal of an electric connector concerning the present invention. It is a perspective view of a conductive terminal of an electrical connector according to the present invention.

  Hereinafter, an embodiment of the electrical connector 1 of the present invention will be described with reference to FIGS.

  The electrical connector 1 is mounted on a printed circuit board (not shown) and connected to an IC package (not shown), and includes an insulating housing 10 and conductive terminals 20 held by the insulating housing.

  The insulating housing 10 has a rectangular shape, and a plurality of terminal accommodating passages 11 in a matrix shape are formed.

  Referring to FIG. 2, each terminal accommodating passage 11 has a frame shape, a first side wall 111 is partitioned by a concave portion 112 at an intermediate portion thereof, and contact portions 113 are formed at both ends thereof. The second side wall 121 facing the first side wall 111 is partitioned by a recess 122 in the middle part, and columnar bodies 123 are formed at both ends thereof. The corners of the columnar body 123 located on the terminal accommodating passage 11 side are cut off to form inclined surfaces 124 respectively. In the direction from the two side walls toward the first side wall, the slope portions 124 extend to the terminal accommodating passage 11 so as to form a letter H shape, whereby the space of the terminal accommodating passage 11 is increased. . A stepped first cut 132 and a second cut 133 positioned lower than the first cut 132 are formed on both third side walls 131 connecting the first side wall 111 and the second side wall 121, respectively. ing.

  Referring to FIG. 3, the conductive terminal 20 is manufactured by processing with a metal plate. Each conductive terminal 20 includes a base portion 21, holding portions 22 at both ends of the base portion 21, and a pair of elastic arms 23 that extend upward from the top surface of the base portion 21 and are flush with the base portion 21. . The elastic arms 23 extend in a wave-like manner, and at the end of each elastic arm 23, the contact arms 24 are bent and extended, and the pair of contact arms 24 has a letter C shape in a direction away from the elastic arms 23. Tapering outwards to form a shape. On the bottom surface of the base portion 21 opposite to the elastic arm 23, a solder tail portion 25 disposed in parallel with the contact arm 24 is formed by bending.

  Referring to FIG. 2, each conductive terminal 20 is accommodated corresponding to the terminal accommodating passage 11. The holding portion 22 is held by interference inside the terminal accommodating passage 11. The elastic arm 23 of the conductive terminal 20 is disposed so as to extend along the first side wall 111. The contact arm 24 extends in the direction of the second side wall 121.

  When using the IC package, the conductive pins of the IC package are inserted into the space between the contact arm 24 and the columnar body 123. Next, by moving the conductive pin in the direction of the contact arm 24, electrical connection can be achieved between the conductive pin of the IC package and the conductive terminal 20, and at the same time, the contact portion 113 of the first side wall 111. The elastic arm 23 of the conductive terminal 20 can be prevented from being excessively deformed. Since the step-shaped first cut 132 and second cut 133 are formed, when the conductive pin contacts the contact arm 24 of the conductive terminal 20, the contact arm 24 is elastically deformed outward of the columnar body 123. It becomes possible to do.

  Since the elastic arm 23 of the conductive terminal 20 according to the present invention extends in a wavy manner, the length of the elastic arm 23 increases and has an excellent elastic deformation capability.

  Although the present invention has been described in detail with reference to the best embodiment, the present embodiment is merely illustrative and is not limited thereto. Further, the above description is intended to be within the scope of the claims of the present invention, such as modification of details or changes that can be made based on the present invention.
