Description

Technical Field

[0001] The present invention relates to a connector assembly including a first connector and a second connector that can be fitted to each other.

Background Art

[0002] A connector assembly including a first connector and a second connector that can be fitted to each other is disclosed, for example, in Patent Document 1.

[0003] Referring to FIG. 18, the connector assembly 90 of Patent Document 1 includes a first connector 92 and a second connector 94 that can be fitted along the vertical direction. The first connector 92 is a receptacle, and the second connector 94 is a plug.

[0004] As shown in FIG. 18, the first connector 92 has a first terminal 921, and the second connector 94 has a second terminal 941. The first terminal 921 has a C-shaped spring portion 923. The first terminal 921 also has a first contact portion 925 and a first additional contact portion 927. The first contact portion 925 is supported by the spring portion 923 and is located near the tip of the spring portion 923. On the other hand, the first additional contact portion 927 is located near the base end of the spring portion 923. The second terminal 941 has a U-shaped portion 943. The second terminal 941 also has a second contact portion 945 and a second additional contact portion 947.

[0005] As understood from FIG. 18, when the first connector 92 and the second connector 94 are fitted, the spring portion 923 of the first terminal 921 is elastically deformed to allow the entry of the U-shaped portion 943 of the second terminal 941. As a result, the first contact portion 925 and the second contact portion 945 come into contact with each other, and the first additional contact portion 927 and the second additional contact portion 947 come into contact with each other.

[0006] As shown in Figure 18, the first terminal 921 further has a first locking portion 929. The first locking portion 929 is located near the first additional contact portion 927 and away from the first contact portion 925. The second terminal 941 further has a second locking portion 949. The second locking portion 949 is located near the second additional contact portion 927 and away from the second contact portion 945.

[0007] As can be seen from Figure 18, when the first connector 92 and the second connector 94 are mated, moving the second connector 94 in the direction of separating it from the first connector 92 causes the second locking part 949 to abut against the first locking part 929. To separate the second connector 94 from the first connector 92, a force is required to elastically deform the spring part 923 until the second locking part 949 overcomes the first locking part 929, i.e., an extraction force (>holding force). The first locking part 929 and the second locking part 949 also affect the force (insertion force) required when mating the first connector 92 and the second connector 94. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2019-46670 [Overview of the project] [Problems that the invention aims to solve]

[0009] In the connector assembly 90 of Patent Document 1, the second terminal 941 does not undergo substantial elastic deformation. Therefore, the insertion force and extraction force (retention force) in the connector assembly depend on the elastic force of the first terminal 92. Here, in the first terminal 921, the first locking portion 929 is located on the base end side of the spring portion 923, not the tip side, and the first locking portion 929 is difficult to move. Therefore, if the locking force by the first locking portion 929 is strengthened to increase the retention force, the insertion force will also increase. However, there is a demand for increasing the retention force in a connector assembly without increasing the insertion force.

[0010] The present invention aims to provide a connector assembly that can increase the holding force without increasing the insertion force. [Means for solving the problem]

[0011] The present invention relates to a connector assembly comprising a first connector and a second connector as a first connector assembly, The first connector is located below the second connector in the vertical direction. The first connector and the second connector are matable along the vertical direction, The first connector comprises a first terminal and a first retaining member, The first retaining member holds the first terminal, The first retaining member has a restricting portion, The first terminal has an elastically deformable spring portion, a first contact portion, a first recess, a first locking portion, and a restricted portion. The first contact portion, the first recess, the first lock portion, and the restricted portion are supported by the spring portion. The first locking portion is adjacent to the first recess, The first locking portion has a first intersecting surface that intersects with the vertical direction, The restricted portion is located below the restricted portion in the vertical direction and faces the restricted portion. The aforementioned second connector comprises a second terminal and a second retaining member. The second retaining member holds the second terminal, The second terminal has an insertion end, a second contact portion, a second recess, and a second locking portion. The insertion end is located at the lower end of the second terminal, The second locking portion has a second intersecting surface that intersects with the vertical direction, The second recess is adjacent to the second locking portion, The second contact portion is located above the second recess, The second contact portion is in contact with the first contact portion in a fitted state where the first connector and the second connector are fitted. In the fitted state, the first locking portion and the second locking portion are located between the first recess and the second recess in a width direction orthogonal to the vertical direction. In the fitted state, the first locking portion and the second locking portion face each other in the vertical direction. Provided is a connector assembly.

[0012] Further, the present invention provides a first connector assembly as a second connector assembly, The first terminal has an arc-shaped portion. The first contact portion and the restricted portion are provided on the arc-shaped portion. The restricted portion is located above the first contact portion. Provided is a connector assembly.

[0013] Further, the present invention provides a second connector assembly as a third connector assembly, The restricting portion has an inclined surface that obliquely intersects both the vertical direction and the width direction, In the width direction, the position of the inclined surface of the restricting portion partially overlaps the arc-shaped portion.​​​​​​​​​​​​​​​​​​​​

[0016] In addition, the present invention provides, as a sixth connector assembly, any one of the first to fifth connector assemblies, where the first terminal further has a held portion held by the first holding member and a first additional contact portion located between the held portion and the spring portion, the second terminal has an additional linear portion extending upward from the insertion end portion, a second additional contact portion is provided on the additional linear portion, and the second additional contact portion is in contact with the first additional contact portion in the fitted state. A connector assembly is provided.

[0017] In addition, the present invention provides, as a seventh connector assembly, any one of the first to sixth connector assemblies, where, in a state where the first locking portion is in contact with the second locking portion and the restricted portion is in contact with the restricting portion, a first angle, which is an angle formed by a tangent line at the contact position between the first locking portion and the second locking portion and the width direction, is larger than a second angle, which is an angle formed by a tangent line at the contact position between the restricted portion and the restricting portion and the width direction. A connector assembly is provided.

Effects of the Invention

[0018] In the connector assembly of the present invention, the first contact portion, first locking portion, and restricted portion of the first terminal of the first connector are supported by a spring portion. The restricted portion is located below the restricting portion of the first retaining member and faces the restricting portion. When separating the first connector and the second connector from each other in a mated state, the second locking portion of the second terminal pushes the first locking portion of the first terminal upward. At this time, the restricted portion of the first terminal also tries to move upward, but the restricting portion of the first retaining member restricts this movement. As a result, a retaining force greater than the retaining force dependent on the elastic force of the spring portion can be obtained. On the other hand, the insertion force is the insertion force dependent on the elastic force of the spring portion. Thus, the connector assembly of the present invention can increase the retaining force without increasing the insertion force. [Brief explanation of the drawing]

[Figure 18] This is a cross-sectional view of the connector assembly described in Patent Document 1. The first connector and the second connector are in a mated state, with the two connectors engaged with each other. [Modes for carrying out the invention]

[0020] Referring to Figures 1 and 2, a connector assembly 10 according to one embodiment of the present invention comprises a first connector 12 and a second connector 14. In this embodiment, the first connector 12 and the second connector 14 are matable along the vertical direction. In the mated or matable state, the first connector 12 is located below the second connector 14 in the vertical direction. In this embodiment, the first connector 12 is a receptacle, and the second connector 14 is a plug. In this embodiment, the "vertical direction" is the Z direction. The +Z direction is upward, and the -Z direction is downward.

[0021] As shown in Figures 3 and 4, the first connector 12 comprises a plurality of first terminals 20 and a first retaining member 30. Each of the first terminals 20 is formed, for example, by punching and bending a metal plate. The first retaining member 30 is made of, for example, an insulating resin. The first retaining member 30 holds the first terminals 20. In this embodiment, the first terminals 20 are press-fitted into and held in the first retaining member 30. However, the present invention is not limited thereto. The first terminals 20 may be held in the first retaining member 30 by another method such as insert molding.

[0022] As shown in Figures 3 and 4, in this embodiment, there are 16 first terminals 20. The first terminals 20 are arranged in two rows. However, the present invention is not limited to this. The number of first terminals 20 can be one or more. Also, the first terminals 20 may be arranged in one row or three or more rows.

[0023] As can be seen from Figures 5 to 7, in this embodiment, two adjacent first terminals 20 in the lateral direction perpendicular to the vertical direction are arranged facing the same direction. Also, two adjacent first terminals 20 in the front-to-back direction perpendicular to both the vertical and width directions are arranged facing opposite directions. However, the present invention is not limited to this. Two adjacent first terminals 20 in the lateral direction may be facing opposite directions. Also, two adjacent first terminals 20 in the front-to-back direction may be facing the same direction. In this embodiment, the lateral direction is the Y direction, and the front-to-back direction is the X direction.

[0024] As shown in Figure 6, each of the first terminals 20 has a fixed portion 201, a held portion 203, a connecting portion 205, a first additional contact portion 207, a spring portion 209, a first contact portion 217, a first recess 219, a first locking portion 221, and a restricted portion 225. The fixed portion 201 extends laterally. The fixed portion 201 is the part that is fixed to an object (not shown), such as a circuit board, when the first connector 12 is mounted on such an object. The held portion 203 extends upward from one end of the fixed portion 201. The held portion 203 is the part that is held by the first holding member 30. The connecting portion 205 extends in an arc from one end of the held portion 203. The connecting portion 205 connects the held portion 203 and the spring portion 209. The spring portion 209 extends from one end of the retained portion 203 in a C-shape, then extends in an arc, and further extends diagonally downward.

[0025] As shown in Figure 6, the first additional contact portion 207 is located between the held portion 203 and the spring portion 209. In other words, the first additional contact portion 207 is provided at the boundary between the held portion 203 and the spring portion 209. However, the first additional contact portion 207 is not essential in this invention. Nevertheless, the first additional contact portion 207 is effective in improving the reliability of the electrical connection between the first terminal 20 and the corresponding second terminal 40.

[0026] As shown in Figure 6, the spring portion 209 has a main spring portion 211, an arc-shaped portion 213, and a tip portion 215. The first contact portion 217, the first recess 219, the first lock portion 221, and the restricted portion 225 are supported by the spring portion 209. More specifically, the first contact portion 217 and the restricted portion 225 are provided on the outer circumferential surface of the arc-shaped portion 213. The first contact portion 217 is located closer to the tip portion 215 than the restricted portion 225. In the lateral direction, the first contact portion 217 faces the first additional contact portion 207. In the vertical direction, the restricted portion 225 is located above the first contact portion 217. The first recess 219 is located between the arc-shaped portion 213 and the tip portion 215. The first recess 219 is recessed upward in the vertical direction and outward in the lateral direction. The first locking portion 221 is located between the arc-shaped portion 213 and the first recess 219, and is adjacent to the first recess 219.

[0027] As can be seen from Figures 13 and 14, the spring portion 209 is elastically deformable. Due to the elastic deformation of the spring portion 209, the first contact portion 217, the first recess 219, the first lock portion 221, and the restricted portion 225, which are supported by the spring portion 209, are movable in the lateral and vertical directions.

[0028] As shown in Figure 1, the first retaining member 30 has a pair of long walls 301, a pair of short walls 303, an island-shaped portion 305, and a bottom portion 307. A connector receiving portion 309 that partially receives the second connector 14 is formed around the island-shaped portion 305.

[0029] As can be seen from Figures 1, 6, and 7, each of the long walls 301 is alternately provided with a first storage section 311 and a second storage section 321 along the front-to-back direction. Furthermore, the island-shaped section 305 is provided with a second storage section 321 and a first storage section 311, corresponding to the first storage section 311 and second storage section 321 provided on the long walls 301.

[0030] As can be seen from Figures 6 and 7, the first housing section 311 houses at least the retained section 203 and a part of the connecting section 205. The second housing section 321 houses at least a part of the arc-shaped section 213 of the spring section 209.

[0031] As shown in Figures 6 and 7, the first retaining member 30 has a restricting portion 313 that defines a part of the second housing portion 321. The restricting portion 313 has an inclined surface 315 that intersects obliquely in both the vertical and width directions. In the vertical direction, the restricting portion 313 is located at least partially above the circular-shaped portion. In addition, in the width direction, the position of the inclined surface 315 of the restricting portion 313 partially overlaps with the arc-shaped portion 213. As a result, the restricting portion 313 faces the restricted portion 225 of the first terminal 20 at a distance. In other words, the restricted portion 225 of the first terminal 20 is located below the restricting portion 313 in the vertical direction and faces the restricting portion 313.

[0032] Referring to Figures 8 and 9, the second connector 14 comprises a plurality of second terminals 40 and a second retaining member 50. The second retaining member 50 holds the second terminals 40. Each of the second terminals 40 is formed, for example, by punching and bending a metal plate. The second retaining member 50 is made of, for example, an insulating resin.

[0033] As shown in Figures 8 and 9, the second retaining member 50 has an upper plate 501, a pair of long walls 503, and a pair of short walls 505. In this embodiment, the second terminal 40 is press-fitted into a housing groove formed in the long wall 503 and held by the second retaining member 50. However, the present invention is not limited thereto. The second terminal 40 may be held by the second retaining member 50 by another method, such as insert molding.

[0034] As can be seen from Figures 10 to 12, the second terminals 40 are arranged to correspond to the first terminals 20 of the first connector 12. More specifically, in this embodiment, two adjacent second terminals 40 in the lateral direction are arranged facing the same direction. Also, two adjacent second terminals 40 in the front-to-back direction are arranged facing opposite directions. However, the present invention is not limited thereto. The number and arrangement of the second terminals 40 only need to correspond to the number and arrangement of the first terminals 20.

[0035] As shown in Figure 11, each of the second terminals 40 has a fixed portion 401 and a U-shaped portion 403. The U-shaped portion 403 has an insertion end 411, a first straight portion (additional straight portion) 413, a second recess 415, and a second straight portion (straight portion) 417. The first straight portion 413 extends upward from one end of the insertion end 411 and is connected to one end of the fixed portion 401. The fixed portion 401 extends laterally. The second recess 415 is located between the other end of the insertion end 411 and the second straight portion 417. The second recess 415 is recessed laterally toward the first straight portion 413. The second straight portion 417 extends upward from the second recess 415. The insertion end 411 is located at the lower end of the second terminal 40.

[0036] As shown in Figure 11, the U-shaped portion 403 is provided with a second additional contact portion 419, a second contact portion 421, and a second locking portion 423. In other words, the second terminal 40 has an insertion end portion 411 and a second recess 415, as well as a second additional contact portion 419, a second contact portion 421, and a second locking portion 423. The second additional contact portion 419 is provided on the first straight portion 413 and faces outward in the lateral direction. The second contact portion 421 is provided on the second straight portion 417 and is located above the second recess 415. The second contact also faces outward in the lateral direction. The second additional contact portion 419 and the second contact face in opposite directions. The second locking portion 423 is located between the second recess 415 and the insertion end portion 411, and the second recess 415 is adjacent to the second locking portion 423.

[0037] As can be seen from Figures 13 and 14, when the first connector 12 and the second connector 14 are mated, the second terminals 40 are received by the connector receiving portion 309 of the first connector 12. Each of the second terminals 40 is then inserted between the first contact portion 217 and the first additional contact portion of the corresponding first terminal 20. Laterally, the distance between the first contact portion 217 and the first additional contact portion of the first terminal 20 is smaller than the width of the second connector 14 defined by the straight portion 417 and the additional straight portion 413 of the second terminal 40. The spring portion 209 of the first terminal 20 elastically deforms when the second terminal 40 is inserted, receiving the second terminal 40 between the first contact portion 217 and the first additional contact portion.

[0038] As can be seen from Figures 14 and 15, the spring portion 209 is elastically deformed, allowing the second locking portion 423 to move downward in the vertical direction relative to the first locking portion 221. The fact that the first locking portion 221 is located near the first contact portion 217 rather than near the first additional contact portion 207 makes it easy to reduce the insertion force in the connector assembly 10. In other words, the fact that the first locking portion 221 is located at the tip side of the spring portion 209 rather than the base side makes it easy to reduce the insertion force in the connector assembly 10.

[0039] As shown in Figure 14 or Figure 15, in the mated state, the first locking portion 221 and the second locking portion 423 are located between the first recess 219 and the second recess 415 in the width direction. Also, in the mated state, the first locking portion 221 and the second locking portion 423 face each other in the vertical direction. The correspondence between the first locking portion 221 and the second locking portion 423 generates the retaining force in the connector assembly 10 of this embodiment.

[0040] As shown in Figure 14 or Figure 15, in the mated state where the first connector 12 and the second connector 14 are mated, the first contact portion 217 contacts the second contact portion 421, and the first additional contact portion 207 contacts the second additional contact portion 419. Having two contacts improves the connection reliability of the connector assembly 10 in this embodiment.

[0041] As can be seen from Figures 15 and 16, when the mated second connector 14 is moved upward relative to the first connector 12, the second locking portion 423 abuts against the first locking portion 221. If the second connector 14 is moved further upward, the second locking portion 423 pushes the first locking portion 221 upward. As a result, the arc-shaped portion 213 moves upward, and the restricted portion 225 abuts against the restricting portion 313. In other words, the restricting portion 313 restricts the upward movement of the restricted portion 225. Here, the restricting portion 313 has a slope 315, which also restricts the lateral movement of the arc-shaped portion 213. However, the restricting portion 313 does not prevent the lateral movement of the arc-shaped portion 213.

[0042] As can be seen from Figures 16 and 17, when the second connector 14 is moved further upward relative to the first connector 12 while the restricting portion 313 is restricting the upward movement of the restricted portion 225, the second locking portion 423 pushes the first locking portion 221 away from the first additional contact portion. As a result, the second locking portion 423 can move upward relative to the first locking portion 221 in the vertical direction. In this way, the second connector 14 can be separated from the first connector 12.

[0043] As can be seen from Figures 14 to 17, when the first connector 12 and the second connector 14 are mated, the restricting portion 313 does not restrict the downward movement of the arc-shaped portion 213. On the other hand, when the first connector 12 and the second connector 14 are separated from each other, the restricting portion 313 restricts the upward and lateral movement of the arc-shaped portion 213. As a result, the connector assembly 10 of this embodiment can have a greater holding force than the insertion force. That is, the holding force of the first connector 12 to the second connector 14 can be increased without increasing the insertion force of the second connector 14 to the first connector 12.

[0044] To appropriately set the insertion force and holding force of the connector assembly 10, as shown in Figure 6, the first locking portion 221 has a first intersecting surface 223 that intersects with the vertical direction. Also, as shown in Figure 11, the second locking portion 423 has a second intersecting surface 425 that intersects with the vertical direction. Here, the first intersecting surface 223 and the second intersecting surface 425 may each be flat or curved. However, it is preferable that at least one of the first intersecting surface 223 and the second intersecting surface 425 is flat. This is because it is possible to avoid a sudden decrease in holding force when separating the first connector 12 and the second connector 14 from each other. In this embodiment, both the first intersecting surface 223 and the second intersecting surface 425 are flat.

[0045] In addition, in order to appropriately set the insertion force and holding force of the connector assembly 10, the relationship between the first locking part 221 and the second locking part 423, and the relationship between the restricted part 225 and the restricting part 313 are set as follows. First, consider the state shown in Figure 16. In this state, the first locking part 221 is in contact with the second locking part 423, and the restricted part 225 is in contact with the restricting part 313. In this state, the angle between the tangent at the contact position between the first locking part 221 and the second locking part 423 and the width direction (first angle) is made greater than the angle between the tangent at the contact position between the restricted part 225 and the restricting part 313 (second angle). In particular, in this embodiment, since both the first intersecting surface 223 and the second intersecting surface 425 are planar, they can be set as follows. As shown in Figure 14, let α be the angle between the second intersecting surface 425 of the second locking part 423 and the width direction. Furthermore, let β be the angle between the tangent at the contact point between the restricted portion 225 and the restricting portion 313 and the width direction. In this case, if the angle θ between the first intersecting surface 223 of the first locking portion 221 and the width direction is θ ≤ α, then assuming there is no friction, β should be set such that α > β. Increasing β will increase the holding force. However, in reality, there is an effect of friction, so if there is not a certain difference between β and α, the displacement of the spring portion will be difficult or impossible. Therefore, by setting β such that α > β while considering the effect of friction, the holding force of the connector assembly 10 can be appropriately set. On the other hand, if both the first intersecting surface 223 and the second intersecting surface 425 are not planar, then, in the state where the first locking portion 221 is in contact with the second locking portion 423 and the restricted portion 225 is in contact with the restricting portion 313, the first and second angles described above must be identified and set so that the first angle is larger than the second angle. Therefore, from a design perspective, it is preferable that both the first intersecting surface 223 and the second intersecting surface 425 are planar.

[0046] Although the present invention has been described above with reference to embodiments, the present invention is not limited to the embodiments described above, and various modifications and changes are possible without departing from the spirit of the present invention. For example, in the above embodiment, the restricted portion 225 was provided on the arc-shaped portion 213 of the spring portion 209, but the restricted portion 225 may be provided on the main spring portion 211. However, providing the restricted portion 225 on the arc-shaped portion 213 makes it easier to reduce the widthwise size of the first connector 12 than providing it on the main spring portion 211.

[0047] Furthermore, in the above embodiment, the surface of the second straight portion 417 on which the second contact portion 421 is provided is flat from the second recess 415 to the tip, but it may also have a flat surface having a predetermined length in the vertical direction. However, if the surface of the second straight portion 417 is flat to the tip, a stable contact pressure can be obtained, resulting in higher contact reliability.

[0048] The connector assembly of the present invention may further have a first additional locking part (not shown) and a second additional locking part (not shown) corresponding to the first locking part 929 and the second locking part 949 of the connector assembly 90 (see Figure 18) described in Patent Document 1. In that case, the connector assembly of the present invention can increase the holding force without increasing the insertion force compared to the connector assembly 90 of Patent Document 1.
