  In the following description, the direction in which the terminal connecting portion of the male terminal extends is described as “extending direction” or “insertion direction”. A direction perpendicular to the extending direction is referred to as a “thickness direction”. A direction orthogonal to the thickness direction and the extending direction is referred to as a “width direction”.

  As shown in FIG. 1, the connector 1 includes a first male terminal 10, a second male terminal 20, and a female terminal 30 as a joint terminal that electrically connects the male terminals 10 and 20. The first male terminal 10 is inserted into the female terminal 30 from one side in the extending direction, and the second male terminal 20 is inserted from the other side in the extending direction.

  As shown in FIG. 2, the first male terminal 10 includes a flat plate-like first terminal connection portion 11 inserted into the female terminal 30, a first conductor crimping portion to which a conductor (not shown) of the electric wire is crimped. Have The 1st terminal connection part 11 is formed in the substantially rectangular plate shape, and is extended below the insertion direction rather than the 1st conductor crimping | compression-bonding part. The first male terminal 10 is fitted into the female terminal 30 by inserting the first terminal connecting portion 11 into the female terminal 30 along the insertion direction in a state where the electric wire is connected to the first conductor crimping portion. .

  As shown in FIG. 2, the second male terminal 20 includes a flat plate-like second terminal connection portion 21 inserted into the female terminal 30, and a second conductor crimping portion to which a conductor (not shown) of the electric wire is crimped. Have The second terminal connection portion 21 is formed in a substantially rectangular plate shape, and extends above the second conductor crimping portion in the insertion direction. The second male terminal 20 is fitted into the female terminal 30 with the second terminal connecting portion 21 inserted into the female terminal 30 along the insertion direction in a state where the electric wire is connected to the second conductor crimping portion. .

  As shown in FIGS. 1 to 3, the female terminal 30 is formed in a substantially square cylindrical shape extending along the insertion direction, and the first terminal into which the first male terminal 10 is inserted on both sides in the insertion direction. The insertion port 31 and the second terminal insertion port 32 into which the second male terminal 20 is inserted are opened.

  The first terminal insertion port 31 opens at one end (upper side) in the insertion direction, and the first terminal connection portion 11 of the first male terminal 10 is inserted from the upper side in the insertion direction. The second terminal insertion port 32 opens at the other end (lower side) in the insertion direction, and the second terminal connection portion 21 of the second male terminal 20 is inserted from the lower side in the insertion direction. And if each male terminal 10 and 20 is inserted in the female terminal 30, the 1st terminal connection part 11 and the 2nd terminal connection part 21 will fit the female terminal 30 in the position which overlaps with an insertion direction. That is, in the connector 1, the male terminals 10 and 20 inserted from the opposite sides of the insertion direction are fitted in positions offset in the thickness direction (direction orthogonal to the insertion direction).

  As shown in FIGS. 3 to 5, in the female terminal 30, there are a first storage chamber 33 that communicates with the first terminal insertion port 31 and a second storage chamber 34 that communicates with the second terminal insertion port 32. Is formed. Further, a leaf spring 40 that partitions the first storage chamber 33 and the second storage chamber 34 is provided inside the female terminal 30.

  The first storage chamber 33 is a part that stores the first terminal connection portion 11. As shown in FIG. 3, the first storage chamber 33 is a space extending downward from the first terminal insertion port 31 along the insertion direction, and the inner wall surface (hereinafter “ One side (left side) in the thickness direction is partitioned by a first inner wall surface 35). The first inner wall surface 35 is a flat surface along the insertion direction, and has a substantially rectangular surface in which the insertion direction is the longitudinal direction and the width direction is the short direction. The first storage chamber 33 is partitioned by the leaf spring 40 on the other side (right side) in the thickness direction.

  The second storage chamber 34 is a part that stores the second terminal connection portion 21. The second storage chamber 34 is provided at a position that is offset in the thickness direction from the first storage chamber 33 and overlaps the first storage chamber 33 in the insertion direction. As shown in FIG. 3, the second storage chamber 34 is a space extending upward along the insertion direction from the second terminal insertion port 32, and the inner wall surface (hereinafter referred to as “second” in the thickness direction of the female terminal 30. The other side (right side) in the thickness direction is partitioned by 36). The second inner wall surface 36 is a flat surface along the insertion direction, and is opposed to the first inner wall surface 35 in the thickness direction so that the insertion direction is the longitudinal direction and the width direction is the short direction. The surface is shaped. The second storage chamber 34 is partitioned by a leaf spring 40 on one side (left side) in the thickness direction.

  The leaf spring 40 is an elastic body that generates a contact load between the male terminals 10 and 20 and the female terminal 30. As shown in FIG. 3, the leaf spring 40 is provided at the center portion of the female terminal 30 in the thickness direction, and is attached to a holding portion 37 formed inside the female terminal 30. The leaf spring 40 has a convex and concave peak and valley in the thickness direction, and has a predetermined length in the insertion direction. As shown in FIGS. 3 and 4, the holding portion 37 is provided at the center portion in the thickness direction of the female terminal 30 and extends in a beam shape so as to connect the wall portions on both sides in the width direction of the female terminal 30. It is. The leaf spring 40 is held inside the female terminal 30 with the end on the upper side in the insertion direction being hooked on the holding portion 37. Moreover, both surfaces of the leaf | plate spring 40 are press surfaces which push each male terminal 10 and 20 to the other side in the thickness direction.

  In the connector 1 in the detached state, the first male terminal 10 and the second male terminal 20 do not contact the leaf spring 40, so that the leaf spring 40 is not elastically deformed. On the other hand, in the connector 1 in the fitted state, the leaf spring 40 is sandwiched between the first terminal connection portion 11 and the second terminal connection portion 21 in the thickness direction (direction orthogonal to the insertion direction) and elastically deformed. When the connector 1 changes from the detached state to the fitted state, the first male terminal 10 and the second male terminal 20 are inserted into the female terminal 30 to elastically deform the leaf spring 40, and this elastically deformed leaf spring. 40 generates urging force on both sides in the thickness direction. That is, the leaf spring 40 generates a force (biasing force) that pushes the first male terminal 10 leftward in the thickness direction, and a force (biasing force) that pushes the second male terminal 20 rightward in the thickness direction. That is, the leaf spring 40 pushes the first terminal connection portion 11 and the second terminal connection portion 21 toward the side away from each other in the direction orthogonal to the insertion direction. Further, the biasing force generates a force that presses one surface of the first terminal connection portion 11 against the first inner wall surface 35 and a force that presses one surface of the second terminal connection portion 21 against the second inner wall surface 36. That is, a contact load is generated at a location where the first terminal connection portion 11 and the first inner wall surface 35 are in surface contact, and a contact load is generated at a location where the second terminal connection portion 21 and the second inner wall surface 36 are in surface contact. . This contact load is a force (holding force) in a direction orthogonal to the insertion direction. As a result, a holding force is generated to prevent the first terminal connection portion 11 from separating from the first terminal insertion port 31 upward in the insertion direction, and the second terminal connection portion 21 is inserted from the second terminal insertion port 32. A holding force is generated to prevent the detachment in the lower direction.

  According to the connector 1 described above, the first male terminal 10 and the second male terminal 20 can be inserted while being shifted in the thickness direction by providing the leaf spring 40 at the central portion in the thickness direction of the female terminal 30. It becomes possible. And in the connector 1 of a fitting state, it fits in the position where the 1st terminal connection part 11 and the 2nd terminal connection part 21 overlapped in the insertion direction. Thereby, in the connector 1 of a fitting state, the magnitude | size in the insertion direction of a male terminal can be reduced in size.

  Furthermore, by providing a leaf spring 40 at the center in the thickness direction of the female terminal 30, the first male terminal 10 and the second male terminal 20 are not aligned in the vertical direction in the insertion direction, but are orthogonal to the insertion direction. It can be inserted by shifting in the (thickness direction). In addition, the force (holding force) for holding the male terminals 10 and 20 inserted from the opposite side in the insertion direction inside the female terminal 30 can be secured by the biasing force of the leaf spring 40. As described above, in the connector 1, contact load is generated on both sides in the thickness direction via the leaf spring 40, so that contact stability in the fitted state can be ensured.

  In addition, the location where the 1st terminal connection part 11 and the 1st inner wall surface 35 surface-contact becomes a contact which connects the 1st male terminal 10 and the female terminal 30 electrically. Similarly, the place where the second terminal connection portion 21 and the second inner wall surface 36 are in surface contact is a contact point for electrically connecting the second male terminal 20 and the female terminal 30. In the fitted connector 1, the first male terminal 10 and the second male terminal 20 are electrically connected via the female terminal 30.

  Further, in the above-described embodiment, the first terminal insertion port 31 opens to the entire end on the upper side in the insertion direction of the female terminal 30, and the second terminal insertion port 32 ends on the lower side in the insertion direction of the female terminal 30. The whole part is open. In this case, the portion of the first terminal insertion port 31 where the first terminal connection portion 11 is inserted and the portion of the second terminal insertion port 32 where the second terminal connection portion 21 is inserted are in the thickness direction. It only needs to be offset. Furthermore, the tip (lower end in the insertion direction) of the first terminal connection portion 11 may penetrate the female terminal 30 and protrude downward in the insertion direction. The tip (the upper end in the insertion direction) of the second terminal connection portion 21 may also penetrate the female terminal 30 and protrude upward in the insertion direction.
