Japanese Patent Application Publication No. 2013-120702

In the connector of Patent Document 1, in order to cause a large current to flow through the conductive member (terminal member), the cross-sectional area of the conductive member may be increased by increasing the thickness or width of the conductive member. However, when the thickness of the conductive member is increased, the flexibility of the conductive member in the thickness direction decreases. Furthermore, if the width of the conductive member is increased, the connector becomes larger in the width direction. In other words, there is room for improvement in allowing a large current to flow through the conductive member, suppressing a decrease in flexibility of the conductive member, and suppressing an increase in size of the connector in the width direction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector that can allow a large current to flow through a conductive member, suppress deterioration in flexibility of the conductive member, and suppress increase in size in the width direction. do.

The connector according to the first aspect includes a fixed housing fixed to a board, a movable housing into which a connection object having a conductor portion is inserted and removed in an insertion/extraction direction, and the fixed housing and the movable housing connected so as to be relatively movable. and a conductive member that is electrically connected to the conductor portion, the conductive member being formed in a plate shape and having a first elastic portion that is elastically deformable at least in the thickness direction. , another conductive member having a second elastic part that is formed in a plate shape, is elastically deformable at least in the thickness direction, and that at least partially overlaps the first elastic part when viewed from the thickness direction. and has.

In the connector according to the first aspect, since it has another conductive member in addition to the first conductive member, the cross-sectional area of the conductive path through which current flows increases compared to a configuration using one conductive member. , a large current can be passed through the conductive member. In addition, since one conductive member and the other conductive member are separate bodies, compared to a configuration in which one conductive member is made thicker to obtain the necessary cross-sectional area, the conductive member is Easy to deform. In other words, a decrease in flexibility of the conductive member can be suppressed. Furthermore, since at least a portion of the second elastic portion overlaps the first elastic portion when viewed from the plate thickness direction, it is necessary to shift one conductive member and the other conductive member in the width direction. Therefore, it is possible to suppress the increase in size of the connector in the width direction.

In the connector according to the second aspect, a first contact portion that comes into contact with the conductor portion is formed closer to the movable housing than the first elastic portion in the one conductive member, and a first contact portion that contacts the conductor portion is formed in the first conductive member. A second contact portion that contacts at least one of the conductor portion and the first contact portion is formed closer to the movable housing than the second elastic portion.

In the connector according to the second aspect, the second contact portion formed closer to the movable housing than the second elastic portion is configured to contact the conductor portion or the first contact portion. In other words, the first elastic part and the second elastic part are not configured to directly contact the conductor part, but are configured to contact the conductor part at a part remote from the part that is elastically deformed. Thereby, compared to a configuration in which the first elastic part and the second elastic part directly contact the conductor part, changes in the contact area between each conductive member and the conductor part can be suppressed.

The first contact portion of the connector according to the third aspect includes a plurality of first terminal portions that are arranged in a width direction perpendicular to the plate thickness direction and the insertion/extraction direction and are brought into contact with the conductor portion. , the second contact portion has a second terminal portion at least partially disposed between the plurality of first terminal portions and in contact with the conductor portion when viewed from the plate thickness direction.

In the connector according to the third aspect, at least a portion of the second terminal portion is arranged between the plurality of first terminal portions when viewed from the board thickness direction. Therefore, when the second terminal section is deformed in the thickness direction, the movement of the second terminal section is less likely to be restricted by the first terminal section. Furthermore, since the space between the first terminal parts is used as a movement space for the second terminal part, in order to secure the movement space, the entire conductive member is shifted in the width direction with respect to the other conductive member. There is no need to place it. In this way, it is possible to prevent the movement of the second terminal portion from being restricted and to prevent the connector from increasing in size.

The first contact portion and the second contact portion of the connector according to the fourth aspect are formed in a plate shape extending in the width direction and the insertion/extraction direction perpendicular to the plate thickness direction and the insertion/extraction direction.

In the connector according to the fourth aspect, since the first contact part and the second contact part are formed in a plate shape extending in the insertion/extraction direction and the width direction, the first contact part and the second contact part are spaced apart in the width direction. The gap in the width direction is reduced compared to a structure composed of a plurality of small pieces. Thereby, the area of the cross section perpendicular to the insertion/extraction direction of the first contact part and the second contact part is ensured, so that a large current can flow through each conductive member.

The one conductive member of the connector according to the fifth aspect is formed with a first fixed side attachment portion that is attached to the fixed housing, and the other conductive member is formed with a second fixed side attachment portion that is attached to the fixed housing. The first fixed-side mounting portion and the second fixed-side mounting portion are in contact with each other in the plate thickness direction.

In the connector according to the fifth aspect, the first fixed-side mounting portion and the second fixed-side mounting portion are attached to the fixed housing in a state in which they are in contact with each other. Therefore, compared to a configuration in which the first fixed-side mounting portion and the second fixed-side mounting portion are mounted apart from each other in the thickness direction, it is possible to suppress the connector from increasing in size.

The one conductive member of the connector according to the sixth aspect is formed with a first movable side attachment portion that is attached to the movable housing, and the other conductive member is formed with a second movable side attachment portion that is attached to the movable housing. The first movable side attachment portion and the second movable side attachment portion are in contact with each other in the plate thickness direction.

In the connector according to the sixth aspect, the first movable side attachment part and the second movable side attachment part are attached to the movable housing in a state in which they are in contact with each other. Therefore, compared to a configuration in which the first movable side attachment portion and the second movable side attachment portion are attached apart from each other in the plate thickness direction, it is possible to suppress the connector from increasing in size.

The first elastic part and the second elastic part of the connector according to the seventh aspect have the same width and thickness in a width direction perpendicular to the thickness direction and the insertion/extraction direction, respectively.

In the connector according to the seventh aspect, the first elastic part and the second elastic part have the same plate thickness and width in the width direction. In other words, since the difference in cross-sectional area between one conductive member and the other conductive member becomes small, it is possible to evenly flow current through the one conductive member and the other conductive member.

According to the present invention, a large current can be passed through the conductive member, a decrease in flexibility of the conductive member can be suppressed, and an increase in size in the width direction can be suppressed.

Further, the second movable side attachment portion 94 is brought into contact with the first movable side attachment portion 74 (see FIG. 6) in the Y direction. The second movable attachment portion 94 is configured to have a shorter length in the Z direction than the first movable attachment portion 74 . The −Z side end of the second movable attachment portion 94 is connected to the Z side end of the folded portion 88D. At both ends of the second movable side mounting portion 94 in the X direction, there are formed protrusions 97 that protrude in a trapezoidal shape toward the X side and the −X side. Note that illustration of the -X side protrusion 97 is omitted.

The second movable side attachment portion 94 is attached to the movable housing 24 (see FIG. 5) by inserting (press-fitting) the protrusion portion 97 into the previously described groove 58A (see FIG. 5) in the Z direction. ing. The length of the second movable side attachment part 94 in the Z direction is longer than the length of the second fixed side attachment part 84 in the Z direction.

The four second terminal portions 96 are arranged side by side at intervals in the X direction and are brought into contact with the plug terminal 14 (see FIG. 2). Further, the four second terminal portions 96 have the same configuration. Further, the four second terminal parts 96 extend from the Z-side end of the second movable-side attachment part 94 toward the Z-side. The second terminal portion 96 is bent into a mountain shape so as to protrude further toward the Y side than the second movable side attachment portion 94 when viewed from the X direction. Further, the second terminal portion 96 is formed into a substantially trapezoidal shape in which the width of the −Z side portion in the X direction is wider than the width of the Z side portion when viewed from the Y direction. There is. The second terminal portion 96 is elastically deformable in the Y direction.

The Z-side ends of the four second terminal portions 96 are arranged at intervals of length L3 in the X direction. The width of the Z-side end of one second terminal portion 96 in the X direction is equal to the length L4. Here, the second socket terminal 82 and the first socket terminal 62 (see FIG. 6) are, for example, the same size as the second movable side attachment part 94 and the first movable side attachment part 74 (see FIG. 6). They have the same configuration except for the differences.

Specifically, the first elastic part 68 and the second elastic part 88 have a thickness in the Y direction, an interval in the X direction (length L1), and a width in the X direction (length L2), respectively. ing. Further, the first terminal portion 76 and the second terminal portion 96 have the same plate thickness in the Y direction, the interval in the X direction (length L3), and the width in the X direction (length L4), respectively.

<Assembling the socket connector>
As shown in FIGS. 11 and 12, the first movable side attachment part 74 and the second movable side attachment part 94 are press-fitted into the groove part 58 of the movable housing 24 in a state where they are overlapped in the Y direction, so that the movable housing 24. Then, the movable housing 24 is inserted into the movable space 31 of the fixed housing 22. At this time, the first fixed side attachment part 64 and the second fixed side attachment part 84 are attached to the fixed housing 22 by being press-fitted into the groove part 38 of the fixed housing 22 while being overlapped in the Y direction. Other first socket terminals 62 and second socket terminals 82 are attached to fixed housing 22 and movable housing 24 in a similar manner. As a result, the socket connector 10 is completed.

The conductive portion 60 connects the fixed housing 22 and the movable housing 24 so as to be movable relative to each other in the X direction, the Y direction, and the Z direction, and is electrically connected to the plug terminal 14 . The first fixed side attachment part 64 and the second fixed side attachment part 84 are in contact with each other in the Y direction. The first movable side attachment part 74 and the second movable side attachment part 94 are in contact with each other in the Y direction.

As shown in FIG. 10A, when the first socket terminal 62 and the second socket terminal 82 are viewed from the −Y side in the Y direction in the assembled state, the four second elastic parts 88 are It overlaps with section 68. Specifically, since the first elastic part 68 and the second elastic part 88 have the same width and interval in the X direction and overlap with each other with the same width, when viewed from the Y direction, the first elastic part 68 is visible, and the second elastic portion 88 is not visible. In other words, the first elastic section 68 is arranged to cover the second elastic section 88.

Note that although the first elastic portion 68 and the second elastic portion 88 appear to overlap when viewed from the Y direction, they are not entirely in contact with each other. Specifically, between the base portions 68A and 88A, between the curved portions 68B and 88B, between the vertical plate portions 68C and 88C, and between the folded portions 68D and 88D, There are gaps between each. Therefore, when the plug connector 12 is connected to the socket connector 10, the elastic deformation of one of the first elastic part 68 and the second elastic part 88 is difficult to be restricted by the other. In other words, the first elastic section 68 and the second elastic section 88 are more likely to be elastically deformed than a configuration using one elastic section that is thick in the Y direction.

As shown in FIG. 10B, when the first socket terminal 62 and the second socket terminal 82 are viewed from the Y side in the Y direction in the assembled state, the Z side ends of the four second terminal parts 96 are It is arranged between four first terminal parts 76 adjacent to each other in the direction. In other words, the four first terminal sections 76 and the four second terminal sections 96 are arranged alternately in the X direction. Furthermore, the Z-side ends of the four second terminal parts 96 are arranged on the -Z side with respect to the Z-side ends of the four first terminal parts 76. That is, the four first terminal parts 76 and the four second terminal parts 96 are arranged in a zigzag shape in the X direction. The first terminal portion 76 and the second terminal portion 96 are then brought into contact with the plug terminal 14 (see FIG. 2).

<Amount of deflection of leaf spring>
Although not shown, the amount of deflection (amount equivalent to flexibility) δ [mm], the load P [N], the distance L [mm] from the fulcrum to the point where the load P acts, and the longitudinal elasticity of the leaf spring are omitted. The coefficient E [N/mm ² ] and the second moment of area I [mm ⁴ ]. In this case, the amount of deflection δ is expressed as δ=(P×L ³ )/(3×E×I). Further, the cross-sectional moment of inertia I is expressed as I=b×h ³ /12, where the width b [mm] and the plate thickness h [mm] of the leaf spring. From these relational expressions, it can be seen that the flexibility increases as the plate thickness h becomes thinner. In particular, the plate thickness h has a third power effect on flexibility.

[Action and effect]
Next, the functions and effects of the socket connector 10 of the first embodiment will be explained with reference to FIGS. 1 to 12.

When the plug terminal 14 is inserted into the insertion port 46A of the movable housing 24 and moved toward the −Z side, the plug terminal 14 comes into contact with the first terminal portion 76 and the second terminal portion 96. In other words, when the plug connector 12 and the socket connector 10 are connected, a circuit (not shown) on the first board 16 and a circuit (not shown) on the second board 18 are electrically connected. At this time, the plug terminal 14 is held in the socket connector 10 by the elastic force (restoring force) that causes the first terminal portion 76 and the second terminal portion 96 to return to their original positions.

Since the socket connector 10 includes the second socket terminal 82 in addition to the first socket terminal 62, the cross-sectional area of the conduction path through which current flows increases compared to a configuration using one conduction member. Therefore, a large current can flow through the first socket terminal 62 and the second socket terminal 82 (conducting portion 60).

Furthermore, since the first socket terminal 62 and the second socket terminal 82 exist as separate bodies, the first socket terminal 62 The plate thickness of the second socket terminal 82 and the plate thickness of the second socket terminal 82 are respectively thinner. Here, as described above, the thinner the plate thickness, the greater the amount of deflection (including the amount of deformation in the torsional direction) of the leaf spring. Therefore, it is easy to deform the first socket terminal 62 and the second socket terminal 82 in the Y direction and the X direction, respectively. That is, a decrease in flexibility of the first socket terminal 62 and the second socket terminal 82 can be suppressed.

In addition, since the second elastic portion 88 is arranged to overlap the first elastic portion 68 when viewed from the Y direction, it is not necessary to shift the first socket terminal 62 and the second socket terminal 82 in the X direction. Therefore, it is possible to suppress the socket connector 10 from increasing in size in the X direction. That is, in the socket connector 10, a large current can be passed through the first socket terminal 62 and the second socket terminal 82, and a decrease in flexibility of the first socket terminal 62 and the second socket terminal 82 can be suppressed. , and it is possible to suppress enlargement in the X direction.

Further, in the socket connector 10, the first contact portion 72 and the second contact portion 92 are configured to come into contact with the plug terminal 14. In other words, the first elastic portion 68 and the second elastic portion 88 are not configured to directly contact the plug terminal 14, but are configured such that a portion remote from the portion that is elastically deformed comes into contact with the plug terminal 14. ing. As a result, compared to a configuration in which the first elastic part 68 and the second elastic part 88 directly contact the plug terminal 14, changes in the contact area between the first socket terminal 62 and the second socket terminal 82 and the plug terminal 14 are suppressed. Can be suppressed.

Furthermore, in the socket connector 10, the second terminal portion 96 is arranged between the plurality of first terminal portions 76 when viewed from the Y direction. Therefore, when one of the first terminal section 76 and the second terminal section 96 is deformed in the Y direction, the movement is less likely to be restricted by the other. Furthermore, since the space between the first terminal parts 76 is used as a movement space for the second terminal part 96, in order to secure the movement space, the entire second socket terminal 82 is moved relative to the first socket terminal 62. There is no need to shift and arrange them in the X direction. In this manner, in the socket connector 10, the movement of the first terminal portion 76 and the second terminal portion 96 can be prevented from being restricted, and the socket connector 10 can be prevented from increasing in size.

In addition, the socket connector 10 is attached to the fixed housing 22 with the first fixed side attachment part 64 and the second fixed side attachment part 84 in contact with each other. Therefore, compared to a configuration in which the first fixed side mounting part 64 and the second fixed side mounting part 84 are mounted apart in the Y direction, the space required for mounting is smaller, so that the socket connector 10 in the Y direction is It is possible to suppress the increase in size. Furthermore, since the first fixed-side mounting part 64 and the second fixed-side mounting part 84 are mounted in a stacked state, the first socket terminal 62 and the second socket terminal 82 can be mounted to the fixed housing 22 with one press fit.

Further, the socket connector 10 is attached to the movable housing 24 with the first movable side attachment portion 74 and the second movable side attachment portion 94 in contact with each other. Therefore, compared to a configuration in which the first movable-side mounting portion 74 and the second movable-side mounting portion 94 are mounted apart in the Y direction, the space required for mounting is smaller, so that the socket connector 10 in the Y direction is It is possible to suppress the increase in size. Furthermore, since the first movable side attachment part 74 and the second movable side attachment part 94 are attached in a stacked state, the first socket terminal 62 and the second socket terminal 82 can be attached to the movable housing 24 by one press fit.

Additionally, in the socket connector 10, the first elastic part 68 and the second elastic part 88 have the same plate thickness in the Y direction and the same width in the X direction. In other words, since the difference in cross-sectional area between the first socket terminal 62 and the second socket terminal 82 becomes smaller, current can be passed through the first socket terminal 62 and the second socket terminal 82 equally.

The configuration other than the insertion port 108 is the same as that of the movable housing 24. The width of the insertion port 108 in the Y direction is larger than the width of the insertion port 46A in the Y direction. Thereby, the plug terminal 114 can be inserted into the inside of the movable housing 102 through the insertion port 108 in the Z direction. The width of the insertion port 108 in the X direction is equal to the width of the insertion port 46A in the X direction.

At both ends of the first contact portion 117 in the X direction and on the -Z side, protrusions (not shown) that protrude in a trapezoidal shape toward the X side and the -X side are formed. The first contact portion 117 is attached to the movable housing 102 by inserting this protrusion into the groove 58A in the Z direction. In other words, the first contact portion 117 is also configured as an example of the first movable side attachment portion.

<Second socket terminal>
The second socket terminal 106 is made of a plate-shaped conductive metal and is formed by press working. Further, the second socket terminal 106 has a second fixed side attachment part 84, a second board attachment part 86, a second elastic part 88, and a second contact part 118. The second fixed side attachment part 84, the second board attachment part 86, the second elastic part 88, and the second contact part 118 are integrated.

The second contact portion 118 is a portion of the second socket terminal 106 that is formed closer to the Y side (on the movable housing 102 side) than the second elastic portion 88 . Specifically, the second contact portion 118 is formed into a single plate shape extending in the Z direction and the X direction, for example. Furthermore, when viewed from the Y direction, the second contact portion 118 is formed into a substantially square shape having one set of two sides along the X direction and one set of two sides along the Z direction. .

At both ends of the second contact portion 118 in the X direction and on the -Z side, protrusions (not shown) that protrude in a trapezoidal shape toward the X side and the -X side are formed. The second contact portion 118 is attached to the movable housing 102 by inserting this protrusion into the groove 58A in the Z direction. In other words, the second contact portion 118 is also configured as an example of a second movable side attachment portion.

Further, the second contact portion 118 is sandwiched between the movable housing 102 and the first contact portion 117 in the Y direction. That is, the second contact portion 118 is in contact with the first contact portion 117. Furthermore, when viewed from the Y side, the second contact portion 118 is covered by the first contact portion 117 and is configured not to come into contact with the plug terminal 114.

The socket connector 100 is formed by attaching the first fixed side attachment part 64 and the second fixed side attachment part 84 to the fixed housing 22, and by attaching the first contact part 117 and the second contact part 118 to the movable housing 102. Ru. In the state in which the socket connector 100 is formed, the second elastic portion 88 is overlapped with the first elastic portion 68 when viewed from the Y direction.

[Action and effect]
Next, the functions and effects of the socket connector 100 of the second embodiment will be explained.

When the plug terminal 114 shown in FIG. 13 and the first contact portion 117 are brought into contact, the first substrate 16 (see FIG. 1) and the second substrate 18 (see FIG. 2) are electrically connected. Since the socket connector 100 includes the second socket terminal 106 in addition to the first socket terminal 104, the cross-sectional area of the conduction path through which current flows increases compared to a configuration using one conduction member. Therefore, a large current can flow through the first socket terminal 104 and the second socket terminal 106 (conducting portion 103).

Furthermore, since the first socket terminal 104 and the second socket terminal 106 exist as separate bodies, the first socket terminal 104 The plate thickness of the second socket terminal 106 and the plate thickness of the second socket terminal 106 become thinner. Here, as described above, the thinner the plate thickness, the greater the amount of deflection (including the amount of deformation in the torsional direction) of the leaf spring. Therefore, it is easy to deform the first socket terminal 104 and the second socket terminal 106 in the Y direction and the X direction, respectively. That is, a decrease in flexibility of the first socket terminal 104 and the second socket terminal 106 can be suppressed.

In addition, since the second elastic part 88 is arranged to overlap the first elastic part 68 when viewed from the Y direction, it is not necessary to shift the first socket terminal 104 and the second socket terminal 106 in the X direction. Therefore, it is possible to suppress the socket connector 100 from increasing in size in the X direction. In other words, in the socket connector 100, a large current can be passed through the first socket terminal 104 and the second socket terminal 106, and a decrease in flexibility of the first socket terminal 104 and the second socket terminal 106 can be suppressed. , and it is possible to suppress enlargement in the X direction.

Further, in the socket connector 100, the first contact portion 117 and the second contact portion 118 are formed in a flat plate shape extending in the Z direction and the X direction. The gap in the X direction is reduced compared to a structure composed of a plurality of spaced small pieces. As a result, the area of the cross section perpendicular to the Z direction of the first contact portion 117 and the second contact portion 118 is secured, so that a large current can flow through the first socket terminal 104 and the second socket terminal 106.

Note that the present invention is not limited to the above embodiments.

It is said that the configuration was made in contact with In other words, in the socket connector 120, only the first terminal portion 76 is brought into contact with the plug terminal 14. Further, the width of the first terminal portion 76 in the socket connector 120 in the X direction is, for example, twice the width of the first terminal portion 76 in the socket connector 10 in the X direction.

In the socket connector 120, only the first terminal portion 76 (first contact portion 72) is configured to come into contact with the plug terminal 14, and there is no need to bring the second socket terminal 82 into contact with the plug terminal 14. As a result, the plug connector 12 can be made smaller in the Z direction compared to a configuration in which both the first socket terminal 62 and the second socket terminal 82, which are arranged offset in the Z direction, come into contact with the plug terminal 14. becomes.
