The connection terminal used has at least a plurality of connection terminals, and a configuration in which the connection terminal holders (4) and (4) of the connection terminals are held. Here, the above-mentioned connection terminal has two contact members which are electrically conductive at both ends. The two contact members are connected by a coupling portion having a concave shape and a convex shape on the other side, and are connected by a coil spring. The longitudinal direction of the contact member is biased.

An arm portion, and the first base end portion enters between the two arm portions and at least a second base end portion that is in contact with one of the arm portions; and the coil spring is mounted to be press-fitted into the first contact member at one end The other end portion presses the second contact member, and the first and first contact members are respectively biased in the direction of the first and second front end portions. Further, in the connection terminal of the present invention, in the above invention, the coil spring is characterized in that at least the surface thereof is insulative. Further, in the connection terminal of the present invention, in the above invention, the coil spring has a higher electrical resistivity than the fifth and fourth contact members.

Furthermore, the maps referred to in the following paragraphs are only for the general shape in which the display can be =, large, j, w β y, the inner valley of the praise month - and the positional relationship. That is, the present invention is not limited by the shape, size and position of each figure. Fig. 2 is a cross-sectional view showing the connection terminal of the embodiment of the present invention. Fig. 2 is an exploded perspective view showing the configuration of the main two of the connection terminals shown in the figure. The connection terminal i shown in Fig. 2 is an electrical conduction target between the objects to be connected by contact with each connection object = = Yes: Conductive and one end is in contact with the connection object The second connecting member is substantially in the shape of a flat plate; the conductive member is electrically conductive, and the end portion is electrically connected to the connecting object, and the second contact member is in contact with the first contact member 1 () 2G; and a retractable coil spring 3〇 that is biased in the longitudinal direction of the first contact member Μ and the second contact member 20. The first contact member 10 has, on the coaxial side, a front end portion u (first front end portion) having a plurality of convex portions 11a forming a front end tapered shape; and extending from a base end portion of the front end portion 11 than the front end portion a flange portion 宽度2 of a width; a hub portion 13 extending from an end portion which is different from the flange portion 12 and the front end portion and having a smaller width than the width of the flange portion 12; and a self-and valley portion 13 The end portion 323671 7 201251216 of the flange portion 12 has a base end portion i4 (first base end portion) which is wider than the width of the hub portion 13. The second contact member 20 has, on the coaxial side, an end portion 21 (second front end portion) which is formed before the end portion is tapered, and has a width larger than the width of the front end portion 21 from the base end side of the front end portion 21. Method _ 22; extending from a different end portion from the side of the front end portion of the flange portion 22 to have a width smaller than the width of the flange portion (4) 23; and from the side connected to the hub portion 23 and the flange portion 22 The end portion 24 (the second end portion) having a width in which the width of the comparative portion 23 is small is extended. The base end portion 24 has two arm portions 24a, 24b which are formed in a substantially columnar shape and extend in parallel with each other in the longitudinal direction. The distance between the arms 24a, 24b is more than the width of the base end portion 14. The base end portion 14 enters between the two arm portions 24a, 24b' and is in contact with the wall surfaces of the arm portions 24a, 24b. Further, when the base end portion 14 enters between the arm portions 24a and 24b, an appropriate contact pressure with the arm portion is obtained from a load applied in a direction perpendicular to the fishing axis of the connection terminal 1, and only one of the arm portions is provided. The contact is sufficient, and the arm portions 24a and 24b are provided corresponding to each other. The distance between the arm portions 24a and 24b may be larger than the width of the base end portion 14. The first contact member 1'' and the second contact member 20 are made of a noble metal or a noble metal alloy' and formed by cutting. The noble metal is, for example, a metal such as gold (Au), silver (Ag), platinum (Pt), palladium (Pd) or rhodium (Rh). Further, the noble metal alloy is an alloy containing any of the above noble metals. Further, the noble metal may be coated on the first contact member 10 and the second contact member 20 which are formed of copper, a copper alloy or iron. 323671 201251216 The coil spring 30 is formed by forming a spiral wound wire as shown in Fig. 2 . The diameter of the inner circumference side of the circle is larger than the width of the base end portion 24, and the width of the hub portions 13, 23 is not reached. The coil spring 30 is press-fitted into the plurality of portions 13 at one end as shown in Fig. 1 and the other end is pressed into the hub portion 23 and fixed, and is engaged with the first contact member 10 and the second contact member. The state surrounds the base end portions 14, 24. Further, one end side of the coil spring 30 abuts against the flange portion 12, and an elastic force is applied to the front end portion 11 side of the first contact member 10. Similarly, the other end side of the coil spring 30 abuts against the flange portion 22, and an elastic force is applied to the front end portion 21 side of the second contact member 2''. Further, the step coil spring 30 is not subjected to plane grinding processing at the end portion. Therefore, the axis of the coil spring 3 is offset from the axis of the connection terminal 1 by the expansion and contraction, and the load in the vertical direction is applied to the axis of the connection terminal 1. Further, the coil spring 30 is insulating at least on the surface. The insulation can be ensured by coating the surface of the coil spring 30 with an insulating resin such as enamel, or with an insulating resin or ceramics, or with a first or second The wire of the higher resistance of the contact member is formed into a coil shape. By covering the entire surface of the coil spring 30, it is possible to prevent the allowable current from being lowered due to the heat generated by the coil inductance caused by the coil spring current flowing. Here, referring to Fig. 3, a case will be described in which a force is applied to both ends of the self-connecting terminal. Fig. 3 is a partial cross-sectional view showing the configuration of a connection terminal according to an embodiment of the present invention. As shown in Fig. 3, when the front end portions 11 and 21 of the connection terminal are applied with a force F1 (arrow direction in Fig. 3) toward the respective end portions 14, 24 in the longitudinal direction of the connection terminal, the base end portion 14 is along 9 323671 201251216 of the arms 24a, 24b The wall slides in the longitudinal direction. At this time, the coil spring 3 is compressed, and a contact member ίο and the second contact member 20 exert an elastic force opposite to the weight of the force F1. In this way, the coil spring 3 收缩 contracts and relieves the impact from the outside, and the force in the opposite direction to the force is applied to make the contact state with the object to be connected more reliable. When the front worms 11 and 12 of the connection terminal 实施 according to the embodiment of the present invention are in contact with the object to be connected, the coil spring 3 吸收 absorbs the load due to the contact, and the coil spring 3G In other words, the laws 12 and 22 are applied with a force in a direction opposite to the force applied from the object to be connected to the object to be connected, thereby making the contact with the object of the connection more reliable, thereby facilitating the connection with the both ends of the connection terminal. Further, the electrical conduction between the objects, when the base end portion 14 enters between the arm portions 24a, the distance between the arm ends 24a, 24b is not expanded by the base end portion 14 due to the application of H to the connection terminal 1 (four) In the straight direction, the load of the base end portion Μ /, U 24a 24b is slidably connected, and the conduction-type cancer between the first contact member 1G and the second contact member 2 () can be maintained in a simple configuration. Further, by applying a bottom ring grinding (plane grinding process) to a portion of the coil spring 3 that abuts against the flange portion 12 and the crucible, it is possible to suppress the deviation of the axis of the coil from the connection terminal. The load from the direction perpendicular to the axis of the connection terminal 1 can be made smaller. In this case, the electrical connection between the first contact member 10 and the second contact member 20 is caused by the coil spring 3〇 being contacted with the contact portion of the first contact member 1〇 and the second contact member, and the current is not conducted. The coil spring 30 can be the shortest; f: the electrical conduction between the contact members is reliably achieved. 323671

The angle of the apex of the blade edge shape is determined. Further, the angle of formation of the convex portion 41a can be adjusted by changing the apex angle of the rotary cutter. The second contact member 50 has a front end portion 51 on the same axis (second The front end portion is electrically connected to the object to be connected to form a front end shape which is tapered at the front end; the flange portion 52 extends from the proximal end side of the front end portion 51 and has a larger diameter than the diameter of the front end portion 51; The end portion 53 of the hub portion 53 is different from the side connected to the flange portion 52 and the front end portion 51. And having a diameter smaller than the diameter of the flange portion 52; and the base end portion 54 (second base end portion) extending from the end portion of the side of the hub portion 53 and the flange portion 52, and having a specific hub The diameter of the portion 53 is small. The base end portion 54 has two arm portions 54a and 54b extending in parallel with each other in the longitudinal direction. The distance between the arm portions 54a and 54b is equal to the diameter of the base end portion 44. The base end portion 44 enters between the two arm portions 54a, 54b and is in contact with the wall surfaces of the arm portions 54a, 54b. Moreover, the base end portion 44 only needs to be at least one arm when entering between the arm portions 54a, 54b. The portion may be in contact with each other, and if the arm portions 54a, 54b are provided corresponding to the base end portion, the distance between the arm portions 54a, 54b is not equal to the diameter of the base end portion 44. In the above-described modification, when the base end portion 44 enters between the arm portions 54a, 54b, 'the distance between the arm portions 54a, 54b is not expanded by the base end portion 44', and the base end portion 44 and the arm portion can be maintained. 54a, 54b sliding state, and 12 323671
