Description

Technical Field

[0001] The present invention relates to a connector, and more particularly to a connector including a terminal having a spring portion that supports a contact portion.

Background Art

[0002] There is known a connector including a terminal having a spring portion that supports a contact portion and has high spring characteristics and can suppress a decrease in high-frequency transmission characteristics. This type of connector is disclosed in, for example, Patent Document 1.

[0003] Referring to FIGS. 14 and 15, a terminal 90 of the connector disclosed in Patent Document 1 has a connector contact portion 901, a press-fitting fixing portion 903, a spring portion 905, a board connection portion (contact point) 907, and a loop contact portion 909.

[0004] As shown in FIGS. 14 and 15, the spring portion 905 supports the board connection portion 907. The spring portion 905 is elastically deformable. Due to the elastic deformation of the spring portion 905, the board connection portion 907 is movable in the vertical direction and also movable in the lateral direction orthogonal to the vertical direction. The spring portion 905 has high spring characteristics by having a U-shaped configuration.

[0005] As understood from FIGS. 14 and 15, in the process of connecting a connector (not shown) to a module board (not shown), the board connection portion 907 of the terminal 90 is pressed against a pad (not shown) of the module board by the repulsive force of the spring portion 905 and slides on the pad. Thereby, even when natural oxide films are formed on the respective surfaces of the board connection portion 907 and the pad, those natural oxide films are broken, and the board connection portion 907 and the pad are electrically connected.

[0006] [[ID=2,7]] As can be seen from Figures 14 and 15, during the process of connecting the connector (not shown) to the module board (not shown), the loop contact portion 909 of the terminal 90 contacts the portion between the spring portion 905 and the press-fit fixing portion 903. This shortens the transmission distance from the connector contact portion 901 to the board connection portion 907 compared to the case where the transmission goes through the spring portion 905. As a result, the high-frequency transmission characteristics of the terminal 90 are improved compared to the case where the transmission goes through the spring portion 905.

[0007] [Patent Document 1] Japanese Patent Publication No. 2017-92020 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] The connector described in Patent Document 1 has the problem that when connected to a module board (mating connector), sliding may not occur due to friction between the board connection portion (contact point) 907 and the pad, resulting in poor contact reliability.

[0009] The present invention aims to provide a connector that can improve contact reliability by ensuring that the contact parts slide smoothly when the connector is connected to the mating connector. [Means for solving the problem]

[0010] As can be seen from Figures 14 and 15, in the terminal 90 of the connector of Patent Document 1, the loop contact portion 909 contacts a bent portion located between the spring portion 905 and the press-fit fixing portion 903 when connection with the module board (mating connector, not shown) begins. As the loop contact portion 909 moves along the bent portion, the board connection portion (contact point) 907 moves laterally on the pad (not shown). However, when the loop contact portion 909 reaches the straight portion located directly below the press-fit fixing portion 903, the board connection portion (contact point) 907 does not move laterally on the pad. Therefore, in the connector of Patent Document 1, there is a risk that the board connection portion (contact portion) 907 may not be able to properly wipe (slide) against the pad (mating contact portion) when connected to the module board (mating connector).

[0011] Taking the above points into consideration, the present invention provides a connector that can reliably slide its contact portion when the connector is connected to the mating connector, thereby improving contact reliability.

[0012] Specifically, the present invention provides a first connector that can be connected to a mating connector along the vertical direction, The aforementioned connector is equipped with terminals, The aforementioned mating connector is equipped with mating terminals, The terminal has a receiving portion, an elastically deformable first support portion extending from the receiving portion, a contact portion supported by the first support portion, a second support portion extending from the contact portion, and a stop portion supported by the second support portion. The aforementioned contact portion contacts the mating terminal when the connector connects to the mating connector. During the connection process between the connector and the mating connector, the abutment portion begins contact with the receiving portion at a first position on the receiving portion and slides on the receiving portion until it reaches a second position on the receiving portion when the connection between the connector and the mating connector is completed. The second position is further from the contact portion in the vertical direction than the first position, and further from the first support portion in the lateral direction perpendicular to the vertical direction than the first position. The receiving portion intersects the vertical direction and the horizontal direction at least at the second position. We provide connectors.

[0013] Furthermore, the present invention provides a second connector, which is the first connector, The receiving portion intersects the vertical direction and the horizontal direction between the first position and the second position. We provide connectors.

[0014] Furthermore, the present invention also includes a third connector, which is a first or second connector, The aforementioned connector further comprises a cam section, The first support portion is provided with a cam receiving portion, The cam receiving portion is located between the cam portion and the contact portion in the vertical direction. The cam receiving portion overlaps with the cam portion at least partially in the lateral direction. The contact portion is located between the cam receiving portion and the abutment portion in the lateral direction. During the connection process between the connector and the mating connector, the cam receiving portion abuts against the cam portion, thereby deforming the first support portion to forcibly move the contact portion in the lateral direction. We provide connectors.

[0015] Furthermore, the present invention also includes a fourth connector, which is a third connector, The connector further comprises a retaining member for holding the terminals, The cam portion is provided on the retaining member. We provide connectors.

[0016] Furthermore, the present invention provides a connector, which is the third or fourth connector as a fifth connector, where the first support portion has a recess recessed toward the abutting portion in the lateral direction, the cam receiving portion is provided in a part of the recess, and the cam portion is at least partially located in the recess in a state before the connector is connected to the mating connector. A connector is provided.

Advantages of the Invention

[0017] In the process of connecting the connector and the mating connector, the abutting portion slides on the receiving portion from the first position to the second position. In particular, even when the abutting portion slides near the second position, since the receiving portion intersects at least in the vertical direction and the lateral direction at the second position, the contact portion continues to move in the lateral direction. Thus, the connector of the present invention can reliably slide the contact portion on the mating contact portion, and high contact reliability can be achieved.

[0019] (First Embodiment) Referring to Figures 1 and 2, the connector 30 according to the first embodiment of the present invention, together with the mating connector 50, constitutes a connector assembly 10. When in use, the connector 30 and the mating connector 50 are connected, for example, to a circuit board (not shown) and the mating circuit board (not shown) They are installed in each of them.

[0020] As can be seen from Figures 3 and 4, connector 30 is connectable to mating connector 50 along the vertical direction. 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 1 and 2, the connector 30 comprises a plurality of terminals 32 and a housing (retaining member) 34. The mating connector 50 comprises a plurality of mating terminals 52 and a mating housing 54. The mating terminals 52 correspond one-to-one with the terminals 32 of the connector 30. However, the present invention is not limited to this. The connector 30 only needs to have at least one terminal 32. The housing 34 is not necessarily required. Similarly, the mating connector 50 only needs to have at least one mating terminal 52. The mating housing 54 is not necessarily required.

[0022] Referring to Figures 7 to 9, the connector 30 further comprises a pair of magnets 36 and a pair of yokes 38. The magnets 36 and yokes 38 are attached to the housing 34. On the other hand, the mating connector 50 further comprises a pair of magnetic bodies 56. The magnetic bodies 56 are attached to the mating housing 54. In this embodiment, the connector 30 and the mating connector 50 are connected to each other by an attractive force acting between the magnets 36 and the magnetic bodies 56. However, the present invention is not limited thereto. The mating connector 50 may have magnets instead of magnetic bodies 56. Alternatively, the connector 30 and the mating connector 50 may be connected to each other by another means, such as mating.

[0023] As can be seen from Figures 1 and 2, the housing 34 has a substantially rectangular parallelepiped shape. The housing 34 is elongated in the front-to-back direction perpendicular to the vertical direction, and shorter in the lateral direction perpendicular to both the vertical and front-to-back directions. In this embodiment, the front-to-back direction is the X direction, and the lateral direction is the Y direction. The housing 34 also has a receiving portion 341 that partially receives the mating housing 54. The receiving portion 341 opens downwards. The housing 34 is formed, for example, by injection molding using an insulating resin. However, the present invention is not limited thereto. The shape of the housing 34 is not particularly limited and can be designed arbitrarily.

[0024] As can be seen from Figures 1 and 2, the mating housing 54 has a substantially rectangular parallelepiped shape. The mating housing 54 is smaller than the housing 34 in the front-to-back, lateral, and vertical directions, respectively. In other words, the mating housing 54 is sized to be at least partially accommodated in the receiving portion 341 of the housing 34. The mating housing 54 is formed, for example, by injection molding using an insulating resin. However, the present invention is not limited thereto. The shape of the mating housing 54 is not particularly limited and can be designed arbitrarily. The mating housing 54 only needs to realize the connection between the mating terminal 52 and the corresponding terminal 32.

[0025] As shown in Figures 1 and 2, the terminals 32 are arranged in two rows, forming two terminal rows. The two terminal rows are arranged laterally. In each terminal row, the terminals 32 are arranged at predetermined intervals. The terminals 32 are held in the housing 34. However, the present invention is not limited thereto. The terminals 32 may be arranged in one row or in three or more rows.

[0026] As shown in Figure 8, the magnets 36 are located on both sides of the terminal row in the front-to-back direction. The yokes 38 correspond to each of the magnets 36. As shown in Figures 8 and 9, each of the yokes 38 covers the upper surface of the corresponding magnet 36.

[0027] As shown in Figures 1 and 2, the mating terminals 52 are arranged to correspond to the terminals 32 of the connector 30. More specifically, the mating terminals 52 are arranged in two rows, forming two rows of mating terminals. The two rows of mating terminals are arranged horizontally. In each of the rows of mating terminals, the mating terminals 52 are arranged at predetermined intervals. The mating terminals 52 are held in the mating housing 54.

[0028] As shown in Figure 8, the magnetic material 56 is positioned on both sides of the mating terminal row in the front-to-back direction, corresponding to the magnets 36 of the connector 30. As shown in Figure 9, the magnetic material 56 has an inverted U shape when viewed along the front-to-back direction. However, the present invention is not limited to this. The magnetic material 56 may have a shape other than an inverted U shape, for example, a flat plate.

[0029] Referring to Figures 5 and 6, the two terminals 32 arranged horizontally are rotationally symmetric with respect to an axis extending vertically. Similarly, the two mating terminals 52 arranged horizontally are also rotationally symmetric with respect to an axis extending vertically. Furthermore, as can be seen from Figures 1 and 2, in this embodiment, the two terminal rows of connector 30 are rotationally symmetric with respect to an axis extending vertically. Similarly, the two mating terminal rows of mating connector 50 are rotationally symmetric with respect to an axis extending vertically.

[0030] As shown in Figures 5 and 6, each mating terminal 52 has a fixing portion 521, a holding portion 523, and a mating contact portion 525. The fixing portion 521 extends laterally. The holding portion 523 extends upward from one end of the fixing portion 521. The mating contact portion 525 extends laterally from one end of the holding portion 523. The mating contact portion 525 extends away from the fixing portion 521. The mating terminal 52 is formed, for example, by punching and bending a metal plate. The mating terminal 52 is also held in the mating housing 54, for example, by insert molding.

[0031] As shown in Figures 5 and 6, the terminal 32 has a receiving portion 321, an elastically deformable first support portion 323 extending from the receiving portion 321, a contact portion 325 supported by the first support portion 323, a second support portion 327 extending from the contact portion 325, and a stop portion 329 supported by the second support portion 327. The terminal 32 further has a fixing portion 331 and a holding portion 333. The terminal 32 is formed, for example, by punching and bending a metal plate. The terminal 32 is also held in the housing 34, for example, by press-fitting.

[0032] As shown in Figures 5 and 6, the fixing portion 331 of the terminal 32 extends laterally. The holding portion 333 extends downward in the vertical direction from one end of the fixing portion 331. The receiving portion 321 extends generally diagonally downward from one end of the holding portion 333. Laterally, the receiving portion 321 extends away from the fixing portion 331. The first support portion 323 extends upward, laterally, downward, and further diagonally downward from one end of the receiving portion 321. The first support portion 323 extends in a roughly rectangular shape. The first support portion 323 supports the contact portion 325 at one end. The second support portion 327 extends diagonally upward from the contact portion 325. Laterally, the contact portion 325 extends towards the fixing portion 331. The second support portion 327 supports the abutment portion 329 at one end. The abutment portion 329 faces the receiving portion 321 in both the vertical and horizontal directions.

[0033] As can be seen from Figures 5 and 6, the contact portion 325 of terminal 32 contacts the mating terminal 52 when connector 30 connects to mating connector 50. During the connection process between connector 30 and mating connector 50, the contact portion 325 slides (wipes) over the mating contact portion 525. Meanwhile, during the connection process between connector 30 and mating connector 50, the abutment portion 329 begins contact with the receiving portion 321 at a first position 335 on the receiving portion 321 and slides on the receiving portion 321 until it reaches a second position 337 on the receiving portion 321 when the connection between connector 30 and mating connector 50 is completed.

[0034] As can be seen from Figures 5 and 6, the abutment portion 329 is positioned diagonally above the first position 335 such that it remains in contact with the second position 337 from the first position 335 to the second position 337 on the receiving portion 321. More specifically, the second position 337 is further from the contact portion 325 than the first position 335 in the vertical direction, and further from the first support portion 323 than the first position 335 in the lateral direction perpendicular to the vertical direction. In addition, the receiving portion 321 intersects with both the vertical and lateral directions at least at the second position 337. In this embodiment, the receiving portion 321 intersects with both the vertical and lateral directions between the first position 335 and the second position 337. Since the receiving portion 321 intersects both the vertical and horizontal directions at least at the second position 337, the contact portion 325 continues to move horizontally on the mating contact portion 525 even when the abutment portion 329 slides near the second position 337.

[0035] As shown in Figures 5 and 6, in this embodiment, the receiving portion 321 extends diagonally away from the first support portion 323. This allows the abutment portion 329 to slide on the receiving portion 321 without resisting the spring properties of the first support portion 323, and further allows the contact portion 325 to slide appropriately on the mating contact portion 525. Also, since the abutment portion 329 slides on the receiving portion 321 during the connection process, the length of the movable portion of the second support portion 327 does not change. Therefore, the spring constant of the second support portion 327 does not change, and the contact force of the abutment portion 329 with respect to the receiving portion 321 can be stabilized.

[0036] As shown in Figures 5 and 6, the connector 30 further includes a cam portion 343. In this embodiment, the cam portion 343 is provided on the housing (retaining member) 34. The cam portion 343 is not strictly necessary, but by including the cam portion 343... , as described below This allows for improved contact reliability between connector 30 and the mating connector 50.

[0037] As can be seen from Figures 5 and 6, the first support portion 323 of the terminal 32 is provided with a cam receiving portion 3233. In this embodiment, the first support portion 323 has a recess 3231 that is recessed toward the abutment portion 329 in the lateral direction, and the cam receiving portion 3233 is provided in a part of the recess 3231. The recess 3231 is not necessarily required, but having the recess 3231 allows the length of the first support portion 323 to be increased. This further improves the springiness of the first support portion 323. In addition, the space provided in the housing 34 for accommodating the terminal 32 can be effectively utilized. In other words, the springiness of the first support portion 323 can be improved without increasing the size of the connector 30.

[0038] As shown in Figures 5 and 6, the cam receiving portion 3233 is located between the cam portion 343 and the contact portion 325 in the vertical direction. In the horizontal direction, the cam receiving portion 3233 overlaps with the cam portion 343 at least partially. In this embodiment, the cam portion 343 is located at least partially within the recess 3231 before the connector 30 is connected to the mating connector 50. In the horizontal direction, the contact portion 325 is located between the cam receiving portion 3233 and the abutment portion 329.

[0039] As can be seen from Figures 5 and 6, when connector 30 connects to the mating connector 50, the cam receiving portion 3233 comes into contact with the cam portion 343. This also occurs when there is a large amount of friction between the abutment portion 329 and the receiving portion 321, making it difficult for the abutment portion 329 to slide on the receiving portion 321. When the cam receiving portion 3233 comes into contact with the cam portion 343, the first support portion 323 begins to partially deform in such a way that it moves the contact portion 325 laterally. As a result, the contact portion 325 is forced to move laterally. In this way, the contact portion 325 begins to slide (wipe) on the mating contact portion 525. Consequently, the abutment portion 329 begins to slide on the receiving portion 321. In this way, the connection between connector 30 and the mating connector 50 is achieved.

[0040] As described above, in the connection process between the connector 30 and the mating connector 50 of this embodiment, the abutment portion 329 of the connector 30 slides on the receiving portion 321 from the first position 335 to the second position 337. And while the abutment portion 329 is sliding on the receiving portion 321, the contact portion 325 continues to move laterally. In this way, since the contact portion 325 slides on the mating contact portion 525, the natural oxide film on the contact portion 325 and the mating contact portion 525 can be reliably removed, and high contact reliability between the contact portion 325 and the mating contact portion 525 can be achieved. In particular, even when the abutment portion 329 slides on the receiving portion 321 near the second position 337, the contact portion 325 also moves laterally on the mating contact portion 525. In other words, the contact portion 325 slides over the mating contact portion 525 near the position where it ultimately stops when the connector 30 and the mating connector 50 are connected. In this way, high contact reliability between the contact portion 325 and the mating contact portion 525 can be reliably achieved.

[0041] (Second Embodiment) Referring to Figure 10, the connector 30A according to the second embodiment of the present invention comprises a terminal portion 32A and a pair of cover portions 40. The terminal portion 32A and the cover portions 40 are integrally formed using a single metal plate. The cover portions 40 partially surround the terminal portion 32A.

[0042] As can be seen from a comparison between Figure 5 and Figure 12, the terminal portion 32A of connector 30A is substantially identical to the terminal 32 of connector 30 according to the first embodiment, except that it does not have a fixing portion 331. Therefore, a description of the terminal portion 32A will be omitted.

[0043] As can be seen from Figure 11, each of the cover portions 40 has a main plate portion 42 and a sub-plate portion 44. The main plate portion 42 is a substantially rectangular flat plate perpendicular to the front-rear direction. In the lateral direction, the size of the main plate portion 42 is larger than the size of the terminal portion 32A. Also in the lateral direction, one edge of the main plate portion 42 is connected to the front plate portion 333A of the terminal portion 32A. Here, the front plate portion 333A of the terminal portion 32A corresponds to the holding portion 333 of the terminal 32 in the first embodiment (see Figure 5 or Figure 6).

[0044] As shown in Figure 11, each sub-plate portion 44 of the cover portion 40 is a substantially rectangular flat plate perpendicular to the lateral direction. The sub-plate portion 44 is long in the vertical direction and short in the front-to-back direction. The sub-plate portion 44 extends forward or backward from the other edge of the main plate portion 42 in the lateral direction. In this embodiment, the forward direction is the +X direction and the backward direction is the -X direction.

[0045] As shown in Figure 10, a cam portion 441 is formed on each of the subplate portions 44. The cam portion 441 is formed by cutting and bending a part of the subplate portion 44. The cam portion 441 protrudes laterally toward the terminal portion 32A. The cam portion 441 is not strictly necessary, but by providing the cam portion 441, the contact reliability between the connector 30A and the mating connector (not shown) can be further improved.

[0046] As can be seen from Figures 12 and 13, in this embodiment as well, during the connection process between connector 30A and mating connector (not shown), the abutment portion 329 of connector 30A slides along the receiving portion 321 from the first position 335 to the second position 337. And while the abutment portion 329 is sliding along the receiving portion 321, the contact portion 325 continues to move laterally. In this way, the natural oxide film formed on the contact portion 325 and the mating contact portion (not shown) can be reliably removed, and high contact reliability between the contact portion 325 and the mating contact portion can be achieved. In particular, even when the abutment portion 329 slides along the receiving portion 321 near the second position 337, the contact portion 325 also moves laterally along the mating contact portion. In other words, the contact portion 325 moves laterally near the position where it finally stops when connector 30A and the mating connector are connected. Contact area It slides on top. In this way, the contact point 325 and the mating side Contact area This ensures high contact reliability between the parts. Furthermore, the cam portion 441 assists in initiating the sliding of the abutment portion 329.

[0047] Although the present invention has been described above with reference to embodiments, the present invention is not limited to the above embodiments, and various modifications and changes are possible without departing from the spirit of the present invention. For example, the shape of the first support portion 323 of the terminal 32 is not limited to the above embodiments, and may extend in a manner that roughly forms a triangle or a circle.
