Description

[Technical Field]

[0001] The present invention relates to a connector assembly including a first connector and a second connector that are matable with each other. [Background technology]

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

[0003] 18, a connector assembly 90 in Patent Document 1 includes a first connector 92 and a second connector 94 that can be fitted together in 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. Meanwhile, 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] 18, when first connector 92 and second connector 94 are mated, spring portion 923 of first terminal 921 elastically deforms, allowing U-shaped portion 943 of second terminal 941 to enter. As a result, first contact portion 925 and second contact portion 945 come into contact with each other, and first additional contact portion 927 and second additional contact portion 947 come into contact with each other.

[0006] 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 is spaced apart 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 is spaced apart from the second contact portion 945.

[0007] 18, when the first connector 92 and the second connector 94 are in a mated state, if the second connector 94 is moved in a direction to separate from the first connector 92, the second locking portion 949 abuts against the first locking portion 929. of First connector 92 from Separation requires a force that elastically deforms the spring portion 923, i.e., a removal force (>retention force), until the second locking portion 949 overcomes the first locking portion 929. Note that the first locking portion 929 and the second locking portion 949 also affect the force (insertion force) required to mate the first connector 92 and the second connector 94.

[0008] [Patent Document 1] JP 2019-46670 A Summary of the Invention [Problem to be solved by the invention]

[0009] In the connector assembly 90 of Patent Document 1, the second terminal 941 does not substantially elastically deform. Therefore, the insertion force and removal force (retention force) of 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 end side, and the first locking portion 929 is difficult to move. Therefore, if an attempt is made to increase the retention force by strengthening the lock provided by the first locking portion 929, the insertion force also increases. However, there is a demand for a connector assembly that has an increased retention force without increasing the insertion force.

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, in the present invention, the first additional contact portion 207 is not essential. However, 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 FIG. 6, the spring portion 209 has a spring main portion 211, an arc-shaped portion 213, and a tip portion 215. A first contact portion 217, a first recess 219, a first locking portion 221, and a 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 recess 219 extends upward in the vertical direction. width The first locking portion 221 is located between the arc-shaped portion 213 and the first recessed portion 219 and is adjacent to the first recessed portion 219.

[0027] 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 supported by the spring portion 209 are width It can move in both the forward and backward directions.

[0028] 1, the first holding 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.

Further, second storage sections 321 and first storage sections 311 are provided on the island-shaped section 305 so as to correspond to the first storage sections 311 and second storage sections 321 provided on the long wall 301, respectively.

[0030] 6 and 7, the first accommodating portion 311 accommodates at least the held portion 203 and a part of the connecting portion 205. The second accommodating portion 321 accommodates at least a part of the arc-shaped portion 213 of the spring portion 209.

[0031] 6 and 7, the first holding member 30 has a restricting portion 313 that defines a part of the second accommodating portion 321. The restricting portion 313 has an inclined surface 315 that intersects obliquely with both the vertical direction and the width direction. The restricting portion 313 is at least partially inclined in the vertical direction. arc shape part 213 In addition, the position of the inclined surface 315 of the restricting portion 313 partially overlaps with the arc-shaped portion 213 in the width direction. 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 up-down direction and faces the restricting portion 313.

[0032] 8 and 9, the second connector 14 includes a plurality of second terminals 40 and a second holding member 50. The second holding member 50 holds the second terminals 40. Each of the second terminals 40 is formed, for example, by stamping and bending a metal plate. The second holding member 50 is made of, for example, insulating resin.

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

[0034] 10 to 12, the second terminals 40 are arranged to correspond to the first terminals 20 of the first connector 12. width Two adjacent second terminals 40 in the front-rear direction are arranged facing the same direction. Also, two adjacent second terminals 40 in the front-rear direction are arranged facing in opposite directions. However, the present invention is not limited to this. The number and arrangement of the second terminals 40 may be any number that corresponds to the number and arrangement of the first terminals 20.

[0035] 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 portion 411, a first linear portion (additional linear portion) 413, a second recessed portion 415, and a second linear portion (straight portion) 417. The first linear portion 413 extends upward from one end of the insertion end portion 411 and is connected to one end of the fixed portion 401. The fixed portion 401 has width The second recess 415 is located between the other end of the insertion end 411 and the second linear portion 417. The second recess 415 is width The second linear portion 417 is recessed in the direction toward the first linear portion 413. The second linear portion 417 extends upward from the second recess 415. The insertion end portion 411 is located at the lower end of the second terminal 40.

[0036] 11, the U-shaped portion 403 is provided with a second additional contact portion 419, a second contact portion 421, and a second lock portion 423. In other words, the second terminal 40 has the second additional contact portion 419, the second contact portion 421, and the second lock portion 423 in addition to the insertion end portion 411 and the second recess 415. The second additional contact portion 419 is provided on the first linear portion 413, width The second contact portion 421 is provided on the second linear portion 417 and is located above the second recess 415. Section 421 teeth, width The second additional contact portion 419 and the second contact Section 421 The second locking portion 423 is located between the second recessed portion 415 and the insertion end portion 411, and the second recessed portion 415 is adjacent to the second locking portion 423.

[0037] 13 and 14, when the first connector 12 and the second connector 14 are mated, the second terminals 40 are received in the connector receiving portions 309 of the first connector 12. Then, each of the second terminals 40 is connected to the first contact portions 217 of the corresponding first terminals 20 and the first additional terminals 218. target Contact part 207 is inserted between width In the direction, the first contact portion 217 of the first terminal 20 and the first target Contact part 207 The distance between the first contact portion 217 and the additional straight portion 413 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. When the second terminal 40 is inserted, the spring portion 209 of the first terminal 20 is elastically deformed, and the distance between the first contact portion 217 and the additional straight portion 413 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. target Contact part 207 The second terminal 40 is received between the first terminal 40 and the second terminal 40 .

[0038] 14 and 15 , spring portion 209 elastically deforms, allowing second locking portion 423 to move downward in the vertical direction further than first locking portion 221. Providing first locking portion 221 near first contact portion 217 rather than near first additional contact portion 207 makes it possible to easily reduce the insertion force in connector assembly 10. In other words, providing first locking portion 221 on the tip side rather than the base side of spring portion 209 makes it possible to easily reduce the insertion force in connector assembly 10.

[0039] 14 or 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 up-down direction. The first locking portion 221 and the second locking portion 423 correspond to each other, thereby generating a holding force in the connector assembly 10 of this embodiment.

[0040] 14 or 15, in the mated state in which 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 can improve the connection reliability of the connector assembly 10 of this embodiment.

[0041] As can be seen from Figures 15 and 16, when the second connector 14 in the mated state is moved upward relative to the first connector 12, the second locking portion 423 abuts against the first locking portion 221. When an attempt is made to move the second connector 14 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 regulated portion 225 abuts against the regulating portion 313. In other words, the regulating portion 313 regulates the upward movement of the regulated portion 225. Here, the regulating portion 313 has an inclined surface 315, and the arc-shaped portion 213 width However, the restricting portion 313 restricts the movement in the direction of the arc-shaped portion 213. widthIt does not prevent movement in any direction.

[0042] As can be seen from FIGS. 16 and 17, when the second connector 14 is further moved upward relative to the first connector 12 while the restricting portion 313 restricts the upward movement of the restricted portion 225, the second locking portion 423 locks the first locking portion 221 against the first additional contact portion 225. 207 As a result, second locking portion 423 can be moved up and down above first locking portion 221. In this way, second connector 14 can be separated from first connector 12.

[0043] 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 downward movement of the arc-shaped portion 213. of Upward movement and width As a result, the connector assembly 10 of this embodiment can have a holding force that is greater than the insertion force. In other words, the holding force of the first connector 12 with respect to the second connector 14 can be increased without increasing the insertion force of the second connector 14 with respect to the first connector 12.

[0044] To appropriately set the insertion force and retention force of the connector assembly 10, as shown in FIG. 6, the first locking portion 221 has a first intersecting surface 223 that intersects with the vertical direction. Furthermore, as shown in FIG. 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 be flat. This is because a sudden decrease in retention force can be avoided when the first connector 12 and the second connector 14 are separated from each other. In this embodiment, both the first intersecting surface 223 and the second intersecting surface 425 are flat.

[0045] Additionally, to appropriately set the insertion force and retention force of the connector assembly 10, the relationship between the first locking portion 221 and the second locking portion 423 and the relationship between the regulated portion 225 and the restricting portion 313 are set as follows. First, assume the state shown in FIG. 16. In this state, the first locking portion 221 contacts the second locking portion 423, and the restricted portion 225 contacts the restricting portion 313. In this state, the angle (first angle) formed between a tangent at the contact position between the first locking portion 221 and the second locking portion 423 and the width direction is set to be larger than the angle (second angle) formed between a tangent at the contact position between the regulated portion 225 and the restricting portion 313 and the width direction. Particularly in this embodiment, since both the first intersecting surface 223 and the second intersecting surface 425 are flat, the relationship can be set as follows. As shown in FIG. 14, the angle formed between the second intersecting surface 425 of the second locking portion 423 and the width direction is set to α. Also, the angle formed by the tangent at the contact position between the restricted portion 225 and the restricting portion 313 and the width direction is defined as β. In this case, if the angle θ formed by the first intersecting surface 223 of the first locking portion 221 and the width direction is θ≦α, then β should be set so that α>β, assuming there is no friction. Increasing β increases the holding force. However, in reality, due to the influence of friction, it is necessary to provide a certain degree of difference between β and α in order to prevent the spring portion from 209 When the first intersecting surface 223 and the second intersecting surface 425 are not flat, the first and second angles must be specified and set so that the first angle is greater than the second angle when the first locking portion 221 contacts the second locking portion 423 and the regulated portion 225 contacts the regulating portion 313. Therefore, it is preferable from a design perspective that the first intersecting surface 223 and the second intersecting surface 425 are both flat.

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

[0047] In the above embodiment, the surface of second linear portion 417 on which second contact portion 421 is provided is flat from 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 second linear portion 417 is flat to the tip, stable contact pressure can be obtained, resulting in higher contact reliability.

[0048] The connector assembly of the present invention may further include a first additional locking portion (not shown) and a second additional locking portion (not shown) corresponding to the first locking portion 929 and the second locking portion 949 of the connector assembly 90 (see FIG. 18) described in Patent Document 1. In this 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.
