- the contact surface 82b and the female contact 52 form an intersection line 124b.
- the intersecting lines 121a and 121b formed by the contact surfaces 81a and 81b, the first surface 53 of the male contact 51, and the first surface 54 of the female contact 52 are located on the vertical surface 91, and the contact surface 82a. , 82 b and the first surface 53 of the male contact 51 and the first surface 54 of the female contact 52 are located on the vertical surface 42.
- the intersecting lines 123a and 123b formed by the contact surfaces 81a and 81b, the second surface 55 of the male contact 51, and the second surface 56 of the female contact 52 are not located on the vertical surface 91.
- the intersecting lines 124 a and 124 b formed by the contact surfaces 82 a and 82 b, the second surface 55 of the male contact 51 and the second surface 56 of the female contact 52 are not located on the vertical surface 92.
- the contact surface 81a of the male contact 51 and the contact surface 81b of the female contact 52, and the contact surface 82a of the male contact 51 and the contact surface 82b of the female contact 52 have the same inclination angle with respect to the vertical surfaces 91 and 92, respectively. Therefore, when the male contact 51 and the female contact 52 are electrically connected, they come into surface contact.
- connection terminal 50 configured as described above has the contact surfaces 81a, 81b, 82a, and 82b in which the male contact 51 and the female contact 52 form a certain angle with respect to the vertical surfaces 91 and 92. Therefore, when the male contact 51 and the female contact 52 are compared with a connection terminal having a contact surface parallel to the vertical surfaces 91 and 92, the contact area between the male contact 51 and the female contact 52 is increased. Accordingly, since the contact resistance can be reduced, the amount of heat generated on the contact surfaces 81a, 81b, 82a, 82b can be reduced and the current carrying capacity can be increased. Moreover, since the pressure with respect to contact surface 81a, 81b, 82a, 82b when inserting the male contact 51 in the female contact 52 can be reduced, the life of the connection terminal 50 can be extended.
- the retaining claws 72 and 72 provided at the opening edge of the base 71 of the female contact 52 are locked to the contact portion 62 of the male contact 51 to prevent the retaining contact 62, so that high contact reliability can be ensured. .
- connection terminal 50 in which the contact surfaces 81a and 81b and the contact surfaces 82a and 82b are opposed to each other has been described.
- the contact surfaces 81a and 81b and the contact surfaces 82a and 82b that are opposed may be parallel.
- the contact surfaces 81a and 81b and the contact surfaces 82a and 82b do not need to be inclined with respect to the vertical surfaces 91 and 92, respectively.
- at least one of the contact surfaces 81a and 81b or the contact surfaces 82a and 82b may be inclined with respect to the corresponding vertical surfaces 91 and 92.
- the first surface 53 and the second surface 55 of the male contact 51 and the first surface 54 and the second surface 56 of the female contact 52 are configured as flat surfaces.
- the present invention is not limited to this.
- only the vicinity of the first surfaces 53 and 54 of the male contact 51 and the female contact 52 including the intersection lines 121a, 121b, 122a, and 122b may be flat. .
- first surface 53 and the second surface 55 of the male contact 51 and the first surface 54 and the second surface 56 of the female contact 52 do not necessarily have to be parallel.
- the conductive flat plate 201 as an example of a conductive member
- the insulating flat plate 202 as an example of an insulating member that is laminated on the conductive flat plate 201 and has an inclined side surface 204.
- a cavity 203 is formed in the mother die 200 to be formed. The cavity 203 passes through the insulating flat plate 202 and reaches the conductive flat plate 201.
- An exposed surface 205 which is a part of the conductive flat plate 201 is exposed at the bottom of the cavity 203, and the entire exposed surface 205 is a flat surface.
- the mother die 200 is immersed in an electrolytic solution in an electrolytic bath and disposed so as to face a counter electrode (not shown) that faces the conductive flat plate 201.
- a voltage is applied during By applying a voltage between the conductive flat plate 201 and the counter electrode, the metal in the electrolytic solution is electrodeposited on the exposed surface 205 of the conductive flat plate 201 in the cavity 203.
- a voltage is applied between the mother die 200 and the counter electrode to continue the current flow, and a metal is laminated in the voltage application direction Z.
- the surface facing the exposed surface 205 becomes the side surface 53 of the male contact 51
- the surface facing the opening of the cavity 203 becomes the side surface 55 facing the side surface 53.
- the surfaces facing the inclined side surface 204 become the contact surfaces 81 a and 82 a of the male contact 51. Therefore, the side surfaces 53 and 55 of the male contact 51 are formed in a direction perpendicular to the voltage application direction Z, and the contact surfaces 81a and 82a are formed to be inclined with respect to the voltage application direction Z.
- the entire exposed surface 205 of the conductive flat plate 201 in the cavity 203 is flattened, but the entire surface is not necessarily flat.
- the exposed surface 205 may be formed so that only a partial region including the boundary portion between the conductive flat plate 201 and the insulating flat plate 202 in the cavity 203 is flat. As described above, by flattening a part of the region including the boundary portion, the inclination angle of the contact surfaces 81a and 82a of the male contact 51 can be easily controlled.
- the entire exposed surface 205 may be inclined, or may have a curved surface shape or a step.
- the inclination angle of the contact surfaces 81a and 82a of the male contact 51 is controlled with reference to the voltage application direction Z by controlling the inclination angle of the inclined side surface 204 of the insulating flat plate 202 with respect to the voltage application direction Z. It becomes possible to do. That is, by using the electroforming method, it is possible to form a contact having an arbitrary shape with a contact surface having a highly accurate inclination angle, and a connection terminal having a high degree of design freedom can be obtained.
- the angle of inclination of the contact surfaces 81a and 82a of the male contact 51 is changed by replacing the insulating flat plate 202 and changing the angle of inclination of the inclined side surface 204 instead of replacing the entire mother die 200.
- the female contact 52 can be formed by electroforming using the above manufacturing method. At this time, the contact surfaces 81b and 82b of the female contact 52 are formed to have the same inclination as the contact surfaces 81a and 81 of the male contact 51, so that when the male contact 51 and the female contact 52 are electrically connected to each other, It is possible to make surface contact with the surface.
- the male contact 1 and the female contact 2 according to the first embodiment of the present invention can also be formed by electroforming using the above manufacturing method.
- the contact surfaces 31a, 31b, 32a, and 32b are with respect to the vertical surfaces 41 and 42, and the contact surfaces 81a, 81b, 82a, and 82b are with respect to the vertical surfaces 91 and 92.
- An inclination of 0 to 45 degrees, particularly an inclination of 8 degrees or less is preferable.
- the contact surfaces 31a, 31b, 32a, 32b with respect to the vertical surfaces 41, 42 is smaller than 8 degrees, when the male contact 1 and the female contact 2 are electrically connected, the contact surfaces 31a, 31b, 32a, More than 99% of the force transmitted through 32b acts as a force pressing the contact surface of the corresponding contact. For this reason, it is possible to increase the contact area without substantially impairing the contact force between the contacting contact surfaces.
- connection terminals 10 and 50 of the first and second embodiments the male contacts 1 and 51 and the female contacts 2 and 52 are electrically connected in a fitted state, but the connection terminal according to the present invention is the male contact 1.
- the connection terminal according to the present invention is the male contact 1.
- 51 and the female contacts 2, 52 are not limited to the configuration.
- the male contact 101 may be pressed against the female contact 102 in the width direction X so that the male contact 101 and the female contact 102 come into contact at one place (third embodiment). ).
