A connector to be connected is used. In this connector, two terminals respectively connected to each connection object are brought into contact to electrically connect the connection objects.

  Here, in the connector, it is necessary to continuously connect the electronic devices in an electrically stable state. As a connector for realizing stable electrical conduction, a substantially rectangular hollow space is formed, an elastic piece is provided in the hollow space, and a female terminal (female terminal) coupled to one connection object; A connector having a flat plate shape and a male terminal (male terminal) coupled to the other connection object is disclosed (for example, see Patent Document 1). In this connector, when the male terminal is inserted into the hollow space of the female terminal, the elastic piece is connected by pressing the plate surface of the male terminal.

  Also disclosed is a socket terminal (female terminal) having a sleeve portion formed by forming a substantially cylindrical hollow space along the central axis of the cylinder as a socket terminal connected to a rod-shaped male terminal. (For example, refer to Patent Document 2).

It extends from the end on the side to the same side as the side on which the flat plate portion 32 and the belt-like portion 33 extend, and passes through the base end on the base portion 31 side and is external to the plane orthogonal to the plate surface of the base portion 31. And an arm portion 34 extending to the side. The arm portion 34 has a protruding portion 34a that protrudes in a convex shape in a direction opposite to the side on which the base portion 31 extends from the plate surface.

  The flat plate portion 32 and the belt-like portion 33 are perpendicular to the plate surface of the base portion 31 in a state where a load other than gravity is not applied, and this flat surface passes through the base end where the flat plate portion 32 and the belt-like portion 33 continue.

By electrically conducting the above, stable and reliable electrical conduction can be obtained.

  Further, the protrusion 34a that protrudes to the outside from the through hole 21c is locked to the through hole 11c, so that the load applied in the insertion / removal direction of the terminals 10 and 20, particularly the load in the direction in which the terminals 10 and 20 are separated from each other.

Moreover, according to this Embodiment 1, since the curved part 11b (vertical part 111a) and the side part 21b surface-contact, contact resistance can be made low.

  Moreover, since the maintenance of the connection state of the spring member 30 and the terminals 10 and 20 is maintained by the spring force and the locking of the spring member 30 and the terminals 10 and 20, the force for maintaining the connection state is only the spring force. It is not necessary to make up with, and the spring force to be designed can be reduced. Thereby, since the spring member 30 should just have only the spring force for ensuring conduction | electrical_connection, the reliability of spring member 30 itself can be made high.

  Here, the terminals 40 and 50 and the spring member 60 are formed using a conductive material, as in the first embodiment, and one or more metals selected from the group consisting of silver, tin, and nickel on the surface. Has been plated. Moreover, the terminals 40 and 50 and the spring member 60 are produced by, for example, forming a flat conductive material by pressing or forging so as to have a predetermined shape.

  FIG. 16 is a cross-sectional view schematically showing the configuration of the connector 2 according to the second embodiment. FIG. 16A is a view from above, and FIG. 16B is a view from the side. is there. As shown in FIG. 16, in the state where the terminals 40 and 50 and the spring member 60 are connected, the convex portion 62a is locked to the wall surface of the opening formed by the two concave portions 41c. In this state, the side surface portion 51b is in surface contact with the vertical portion 411a. Further, the first convex portion 62 biases the curved portion 41b (parallel portion 411b) and the bottom surface portion 51a away from the surface parallel to the bottom surface portion 41a of the curved portion 41b. Moreover, the 2nd convex-shaped part 63 urges | biases the direction which the bottom face part 41a and the bottom face part 51a move away with respect to the bottom face parts 41a and 51a.

  As described above, when the curved portion 41b and the side surface portion 51b are in surface contact with each other, it is possible to secure an area for electrical conduction, and between the bottom surface portion 41a and the bottom surface portion 51a via the spring member 60. By electrically conducting the above, stable and reliable electrical conduction can be obtained.

  Further, the protrusion 62a is locked to the wall surface of the opening formed by the two recesses 41c, so that the load applied in the insertion / removal direction of the terminals 40, 50, particularly the load in the direction in which the terminals 40, 50 are separated from each other. Thus, the connection state of the terminals 40 and 50 can be maintained. Further, since the first convex portion 62 and the second convex portion 63 apply a load in a direction orthogonal to the insertion / removal direction of the terminals 40, 50, rotation around an axis parallel to the direction in which the terminals 40, 50 extend is performed. The contact state of the terminals 40 and 50 can be stabilized.

  According to the second embodiment described above, the curved portion 41b and the side surface portion 51b are in surface contact, and the spring member 60 maintains the connection state with respect to the load in the insertion / removal direction of the terminals 40, 50, and the terminals 40, 50. Since the rotation of the terminals 40 and 50 due to the urging in the direction orthogonal to the insertion / removal direction is suppressed, the connection state between the terminals can be stabilized and reliable electrical conduction can be obtained. Further, according to the second embodiment, the curved portion 41b (vertical portion 411a) and the side surface portion 51b are in surface contact, so that the contact resistance can be lowered.

  Further, since the maintenance of the connection state between the spring member 60 and the terminals 40 and 50 is maintained by the spring force and the locking of the spring member 60 and the terminals 40 and 50, the force for maintaining the connection state is only the spring force. It is not necessary to make up with, and the spring force to be designed can be reduced. Thereby, since the spring member 60 should just have only the spring force for ensuring conduction | electrical_connection, the reliability of spring member 60 itself can be made high.

  Further, according to the second embodiment described above, the projecting portion 62a of the spring member 60 can be retained with respect to the terminals 40 and 50, so that the connected state can be maintained and the projecting portion 62a is pressed inside. By doing so, the connection state can be easily released.

  In the first and second embodiments described above, in order to increase the contact areas of the contact portions of the terminals 10 and 40 and the terminals 20 and 50, an uneven shape is formed on the surfaces of the contact portions of the terminals 10 and 40, and An uneven shape obtained by multiplying the uneven shape of the terminals 10 and 40 may be formed on the surface of the contact portion of the terminals 20 and 50.

  In the first and second embodiments described above, the contact portions 11 and 41 (storage portion) have been described as having a substantially rectangular shape in the circumferential direction, but the contact portions 21 and 51 (insertion portion) As long as contact can be ensured, it may be substantially circular.

  As described above, the connector according to the present invention is useful for stabilizing the connection state between terminals and obtaining reliable electrical conduction.
