Abstract
The invention relates to a connector and a connector system. In a terminal used in a conventional socket connector for connecting substrates to each other, a mounting portion for mounting the terminal to the substrate is provided at a position distant from an embedded portion into which the terminal of a plug connector on a side to be connected is embedded in a short-side direction of the connector. Therefore, in the receptacle connector in which the terminals are arranged so as to face each other symmetrically in the short side direction of the connector, there is almost no room for narrowing the width in the short side direction, which hinders miniaturization of the connector. Provided is a receptacle connector configured such that the length of a terminal is shortened and the width of the connector in the short side direction is narrowed by providing an installation part at a position of the terminal far from an inserted part on a surface of the inserted part on the substrate side.
Description
Technical Field
The present invention relates to a connector for connecting substrates, and more particularly, to a connector suitable for high-speed transmission of electrical signals. More specifically, the present invention relates to a terminal structure capable of reducing a connector width, which is a distance from an end of one terminal to an end of another terminal, arranged to face each other in a direction (short-side direction) perpendicular to an axis in a longitudinal direction of the connector, to be smaller than a conventional connector.
Background
As a connector in which a plurality of terminals are arranged and held in a housing by integral molding or the like to connect substrates, for example, there is a connector disclosed in japanese patent application laid-open No. 2017-069133 (patent document 1). The connector is a receptacle-side connector (receptacle connector) to which a plug-side connector (plug connector) is connected, and includes a rectangular housing in which a plurality of terminals are aligned and held in a longitudinal direction.
The receptacle connector and the plug connector can be provided on a printed wiring board, a flexible flat cable, or the like. The substrates can be connected to each other by fitting a receptacle connector provided on the printed wiring board by surface mounting or the like and a plug connector provided at an end portion of the flexible flat cable to each other.
Fig. 16 shows an example of a terminal used in a conventional connector. The terminal 900 is a terminal of a plug connector, the terminal 1000 is a terminal of a receptacle connector, and the shape of each terminal is a shape viewed from the longitudinal direction of the connector. The terminal 900 includes a mounting portion 901, a contact portion 902, an insertion tip portion 903, and a contact portion 904. The mounting portion 901 of the terminal 900 is soldered and mounted on a printed circuit board, a flexible flat cable, or the like. By fitting the fitting tip 903 to the fitted portion 1003 between the contact portion 1001 and the contact portion 1004 of the terminal 1000 on the mating side, the contact portion 902 and the contact portion 904 can be brought into contact with the contact portion 1001 and the contact portion 1004 of the terminal 1000, respectively.
The terminal 1000 includes a contact portion 1001, a spring portion 1002, an embedded portion 1003, a contact portion 1004, a U-shaped bent portion 1005, an extension portion 1006, and an attachment portion 1007. The mounting portion 1007 of the terminal 1000 is soldered and mounted on a printed circuit board, a flexible flat cable, or the like. When the fitting tip 903 of the mating terminal 900 is fitted between the contact portion 1001 and the contact portion 1004 of the terminal 1000, the contact portion 1001 is pressed against the contact portion 902 of the mating terminal 900 by the elastic force of the spring portion 1002, and the contact portion 1001 and the contact portion 1004 can be brought into contact with the contact portion 902 and the contact portion 904, respectively.
Patent document 1: japanese patent laid-open publication No. 2017-069133
In recent years, with the miniaturization and high functionality of electronic devices such as smartphones and mobile terminals, high-density mounting of components such as elements and connectors for connecting substrates on printed wiring boards has been advanced, and miniaturization of the connectors themselves, which are components, has been demanded. However, the housing of the connector can be reduced only to the extent that the terminal can be held, and there is a limit to the miniaturization of the connector. For example, as shown in fig. 16, since the terminals 1000 included in the receptacle connector have a shape in which the mounting portions 1007 are provided at positions distant from the contact portions 1002 and 1004, if the terminals 1000 are arranged symmetrically opposite to each other in the short side direction of the connector as in the conventional connector (see patent document 1), the connector width from the end of one terminal to the end of the other terminal cannot be narrowed.
In other words, since the terminal 1000 of the receptacle connector includes the mounting portion 1007 at a position separated in the short direction (X-axis direction) of the connector from the side having the fitted portion 1003 into which the terminal 900 on the target side is fitted, via the contact portion 1004, the U-shaped bent portion 1005, and the extension portion 1006, it is difficult to shorten the length of the terminal 1000 in the short direction (X-axis direction). Therefore, in the conventional receptacle connector including the terminals 1000 symmetrically in the short side direction (X-axis direction) and facing each other, there is almost no room for narrowing the width in the short side direction (X-axis direction), and miniaturization cannot be achieved.

Each embodiment is described independently, but does not exclude a case where the connector is configured by combining the components of each other.
Fig. 1 shows a connector (receptacle connector) and an object-side connector (plug connector) according to an embodiment of the present invention. The connector of the present invention can be used as an internal component in a small electronic device such as a mobile phone, a smartphone, a digital camera, and a notebook computer. Here, the short-side direction of the connector is set as the X-axis direction, the long-side direction of the connector is set as the Y-axis direction, and the fitting direction of the connector is set as the Z-axis direction. In fig. 1, some of the terminals of the receptacle connector 100 and the plug connector 200 are denoted by the reference numeral "10" or "20", and other reference numerals indicating terminals having the same shape are omitted.
The receptacle connector 100 is mounted on a substrate 1 indicated by a dotted line, and the plug connector 200 is mounted on a substrate 2 indicated by a dotted line. In the embodiment shown in fig. 1, the substrate 1 is a printed wiring substrate, and the substrate 2 is a flexible flat cable, but the present invention is not limited to this embodiment. Here, a component to which a connector such as a printed wiring board and a flexible flat cable is mounted is simply referred to as a "board".
The receptacle connector 100 includes a convex fitting projection 32 extending in a longitudinal direction (Y-axis direction) in a central portion of a rectangular housing 30, and side wall portions 33 supporting the plurality of terminals 10 on both sides in a short-side direction (X-axis direction) of the fitting projection 32. The side wall portions 33 are formed so as to face the fitting convex portions 32 and are arranged in the longitudinal direction (Y-axis direction) of the receptacle connector 100. An end of the plug connector 200 as the counterpart connector is fitted between the fitting convex portion 32 and the side wall portion 33And (5) a seed 20. The fitting convex portion 32 of the receptacle connector 100 is fitted into the fitting concave portion 44 (see fig. 6) of the plug connector 200. On the subject connector side (Z) at both ends of the housing 30 in the longitudinal direction (Y-axis direction)2Side) is provided with a guide 34 in an inclined shape. When the plug connector 200 is fitted to the receptacle connector 100, the housing 40 of the plug connector 200 can be guided to a correct position by the guide portions 34.
The housing 30 of the receptacle connector 100 is made of a resin such as a Liquid Crystal Polymer (LCP), and can hold the plurality of terminals 10 by the fitting convex portion 32, the side wall portion 33, and the resin therebetween by integral molding. The plurality of terminals 10 have the same U-shape and are arranged at equal intervals along the longitudinal direction (Y-axis direction). The plurality of terminals 10 arranged in the longitudinal direction (Y-axis direction) can be provided in 2 rows with a space in the short-side direction (X-axis direction). One U-shaped portion (inner leg 11, see fig. 2) of each terminal 10 is supported by the fitting projection 32, and the other U-shaped portion (outer leg 15, see fig. 2) of each terminal 10 is supported by the side wall 33, and the side wall 33 is arranged in the longitudinal direction (Y-axis direction) with the notch 31 formed by removing a part of the side wall interposed therebetween.
In the embodiment of fig. 1, the side wall portions 33 supporting the terminals 10 are provided with the notch portions 31 on both sides in the longitudinal direction (Y-axis direction), respectively, but the present invention is not limited thereto. For example, the side wall portion 33 supporting each terminal 10 may be provided with a notch portion 31 formed by removing the side wall on at least one side in the longitudinal direction (Y-axis direction).
The plug connector 200 includes a concave fitting recess 44 (see fig. 6) extending in the longitudinal direction (Y-axis direction) in the central portion of the rectangular housing 40, and side wall portions 43 for supporting the terminals 20 on both sides in the short-side direction (X-axis direction) of the fitting recess 44. The side wall portions 43 are arranged in 2 rows along the longitudinal direction (Y-axis direction) of the plug connector 200, and the fitting recesses 44 are formed between the 2 rows of the side wall portions 43.
The housing 40 of the plug connector 200 is integrally molded with a plurality of terminals 20 of the same shape, which are arranged in 2 rows in the longitudinal direction (Y-axis direction) at equal intervals and have an L shape, so that the plurality of terminals 20 can be held. The terminal 20 is soldered to the substrate 2 by the mounting portion 21. The terminal 20 is in contact with the contact portion 16 (see fig. 2) of the target terminal 10 via the contact portion 22, and can be locked to the contact portion 16 (see fig. 2) of the target terminal 10 via the lock portion 23.
In the embodiment of fig. 1, the rows of the terminals in the longitudinal direction (Y-axis direction) of the receptacle connector 100 are 2 rows, but the present invention is not limited thereto, and may be 1 row, for example. The number of terminals of the receptacle connector 100 is 6, but the number is not limited thereto and may be 1 or more. The same applies to the plug connector 200 with respect to the terminal rows and the number of terminals.
Fig. 2 is a view showing only the plurality of terminals 10 in a state of being held by the housing 30 of the receptacle connector 100 shown in fig. 1. The terminal 10 is a U-shaped terminal made of metal such as phosphor bronze and having an inner leg 11 and an outer leg 15. The inner leg 11 includes a contact portion 12 facing the outer leg 15. The fitted portion 13 is a curved portion between the inner leg 11 and the outer leg 15, and has a mounting portion 14 for mounting to a substrate by soldering or the like on a surface opposite to a surface (i.e., a substrate side (Z1 side)) for receiving the terminal 20 of the plug connector 200 as a target connector.
The outer leg 15 includes a contact portion 16 protruding toward the inner leg 11, and a support surface 17, which is a surface opposite to the surface on the inner leg 12 side, is supported by the side wall 33 of the case 30. Further, the portion of the outer leg 15 located at the front end of the contact portion 16 is bent outward in the short direction (X-axis direction) of the connector (X1 or X2 direction), and a top portion 18 is provided between the contact portion 16 and the end portion 19. The end 19 of the outer leg 15 faces outward (in the X1 or X2 direction).
The plurality of terminals 10 are arranged in 1 set of 2, symmetrically opposed in the short side direction (X axis direction) of the housing 30, and arranged along the long side direction (Y axis direction) of the housing 30. In other words, the 2 terminals 10 of the 1-group are arranged such that the inner leg 11 of one terminal 10 and the inner leg 11 of the other terminal 10 are opposed to each other.
Fig. 3 is a view of the receptacle connector according to the embodiment of the present invention as viewed from the substrate side (Z1 side). The housing 30 includes a groove 35 on a surface (bottom surface) on the substrate side for each terminal 10, the groove exposing the mounting portion 14 of the terminal 10. When the connector 100 is mounted on the substrate 1, the groove portion 35 can cover the periphery of the bent mounting portion 14 without a gap so that solder does not enter the inside of the housing 30 from between the mounting portion 14 and the groove portion 35.
Fig. 4 is a view showing only the plurality of terminals 20 in a state of being held by the housing 40 of the plug connector 200 shown in fig. 1. The terminal 20 is made of metal such as phosphor bronze, and has a mounting portion 21 formed by bending outward (X1 or X2 direction) in the short side direction (X axis direction) of the connector and an L-shaped terminal having an insertion portion 24 in the fitting direction (Z axis direction) of the connector.
The end 27 of the mounting portion 21 faces outward in the lateral direction (X-axis direction) (X1 or X2 direction). The fitting portion 24 includes a contact portion 22 on a side toward which the end portion 27 faces, and a contact portion 25 on an opposite side. The contact portion 22 is formed to be recessed from the surface of the fitting portion 24, and the boundary between the surface of the fitting portion 24 and the contact portion 22 recessed from the surface functions as a locking portion 23 capable of locking the contact portion 16 of the terminal 10 of the counterpart connector.
The plurality of terminals 20 are arranged in 1 set of 2, symmetrically opposed in the short side direction (X axis direction) of the housing 40, and arranged along the long side direction (Y axis direction) of the housing 40. In other words, the terminals 20 of the 2 to 1 group are arranged such that the embedded portion 24 (contact portion 25) of one terminal 20 and the embedded portion 24 (contact portion 25) of the other terminal 20 are opposed to each other.
Fig. 5 and 6 are views of the plug connector viewed from the substrate side (Z2 side) and the opposite side (Z1 side). The periphery of the mounting portion 21 is filled with resin forming the case 40 by integral molding without a gap. The support portion 42 extending outward in the short-side direction (X-axis direction) from the side wall portion 43 can support a portion of the L-shaped terminal 20 from the bent portion to the end portion 27. When the mounting portion 21 is mounted on the substrate 2 by soldering, the inclined portion 41, which is the inclined portion of the support portion 42, can prevent the solder from being transferred from the mounting portion 21 to the fitting portion 24.
The housing 40 includes a fitting recess 44 between side wall portions 43 to which the terminals 20 are aligned, and the fitting recess 44 is configured to be fitted to a fitting projection 32 provided at a central portion of the housing 30 of the mating connector.
Fig. 7 is a side view of the receptacle connector and the plug connector shown in fig. 1 as viewed from a short side direction (X-axis direction), and lines a-a and B-B in fig. 7 indicate cut positions of the cross-sectional views shown in fig. 8 and 9. Fig. 8 is a sectional view of the receptacle connector 100 and the plug connector 200, taken along line a-a in fig. 7, of a portion of the terminals 10 included in the receptacle connector 100 and a portion of the terminals 20 included in the plug connector 200. Fig. 9 is a sectional view of the receptacle connector 100 and the plug connector 200 taken along line B-B in fig. 7, the cut-out portion 31 of the housing 30 of the receptacle connector 100 and the side wall portion 43 of the housing 40 of the plug connector 200.
When referring to the sectional view shown in fig. 8 and the sectional view shown in fig. 9, the 2 terminals 10 of the receptacle connector 100 are held by the housing 30 so as to be opposed to each other with the fitting convex portion 32 as the center and so as to be symmetrical in the left-right direction. The 2 terminals 20 of the plug connector 200 are held by the housing 40 so as to be opposed to each other with the fitting recess 44 as the center and so as to be symmetrical in the left-right direction.
The inner leg 11 of each of the 2 terminals 10 is supported on the surface opposite to the surface on which the contact portion 12 is present, by the side surface of the fitting projection 32 provided at the central portion of the housing 30. The outer leg 15 of the terminal 10 has a support surface 17 facing outward in the lateral direction (X-axis direction) and supported by the side wall 33. The 2 terminals 20 are supported by covering the bent portion between the mounting portion 21 and the embedding portion 24 with resin.
The contact portion 16 of the terminal 10 projects from the surface of the side wall portion 33 toward the fitting projection 32, while the contact portion 22 of the terminal 20 projects from the outer surface of the side wall portion 43 toward the outside in the short direction (X-axis direction). The surface of the contact portion 12 of the terminal 10 is coplanar with the surface of the fitting projection 32, and the surface of the contact portion 25 of the terminal 20 is also coplanar with the surface of the inside of the side wall 43. The contact portion 16 protrudes toward the contact portion 12, and the distance between the outer leg 15 and the inner leg 11 is the narrowest between the contact portion 16 and the contact portion 12.
Fig. 10 is a cross-sectional view showing a state in which the receptacle connector and the plug connector according to the embodiment of the present invention are fitted to each other. The cross-sectional view is a cut-away view of the receptacle connector 100 and the plug connector 200 at a portion corresponding to the line a-a in fig. 7. When the fitting tip portion 26 of the terminal 20 is made to enter the fitted portion 13 of the terminal 10, the outer leg portion 15 of the terminal 10 is pressed outward in the short direction (X-axis direction) and deformed because the outer leg portion 15 has elasticity. In other words, the lateral leg 15 can be displaced in a direction away from the medial leg 11. At this time, the side wall portion 33 is also pressed by the support surface 17 of the outer leg portion 15 and is expanded and deformed outward in the short direction (X-axis direction).
The outer leg 15 can maintain the electrical connection between the terminals by pressing the contact portion 16 against the contact portion 22 of the terminal 20 with a force to return to the original state. When a force is applied to the receptacle connector 100 in a direction (Z1 direction) away from the plug connector 200 or when an unintended force is applied to the plug connector 200 in a direction (Z2 direction) away from the receptacle connector 100, the lock portions 23 protruding from the surfaces of the contact portions 22 catch the contact portions 16, and the electrical connection can be prevented from being easily released.
The fitting portion 24 is pressed toward the fitting convex portion 32 by the force of the outer leg portion 15 and the side wall portion 33 to return to the original shape, and the contact portion 25 is pressed against the contact portion 12, whereby electrical connection can be performed. The inner leg portions 11 of the 2 terminals 10 are pressed inward (toward the fitting projection 32), but the fitting projection 32 is applied with substantially uniform force from both sides, so that the inner leg portions 11 are supported by the fitting projection 32 without being deformed.
Fig. 11 shows a connector (receptacle connector) and an object-side connector (plug connector) according to another embodiment of the present invention. The basic structure of both connectors is the same as in the case shown in fig. 1. The receptacle connector 700 includes a convex fitting projection 72 extending in the longitudinal direction (Y-axis direction) at the center of the rectangular housing 70, and side walls 73 supporting the terminals 50 at both ends of the fitting projection 72 in the longitudinal direction (Y-axis direction).
The terminals 60 of the plug connector 800 as the mating connector are fitted between the fitting convex portion 72 and the side wall portion 73. The fitting projection 72 of the receptacle connector 700 is fitted into the fitting recess 84 (see fig. 13) of the plug connector 800. Guide portions 75 are provided in an inclined shape at both side edge portions in the longitudinal direction (Y-axis direction) of the housing 70. When the plug connector 800 is fitted to the receptacle connector 700, the guide portions 75 can guide the housing 80 of the plug connector 800 to a correct position.
The housing 70 of the receptacle connector 700 is made of a resin such as Liquid Crystal Polymer (LCP), and is integrally molded with a plurality of terminals 50 of the same shape in a U shape having 2 rows arranged in the longitudinal direction (Y-axis direction) at equal intervals, so that the plurality of terminals 50 can be held. One U-shaped portion (inner leg 51, see fig. 13) of each terminal 50 is supported by the fitting projection 72, and the other U-shaped portion (outer leg 55, see fig. 13) of each terminal 50 is supported by the side wall 73, and the side wall 73 is arranged in the longitudinal direction (Y-axis direction) with the notch 71 formed by removing a part of the side wall interposed therebetween. The side wall portion 73 can be provided with a thin portion 74 formed by reducing the thickness of the wall on the surface opposite to the surface supporting the outer leg portion 55 (i.e., the outer side in the short direction (X-axis direction)).
The plug connector 800 includes a concave fitting recess 84 (see fig. 14) extending in the longitudinal direction (Y-axis direction) in the central portion of the rectangular housing 80, and side wall portions 83 for supporting the plurality of terminals 60 at both ends in the longitudinal direction (Y-axis direction) of the fitting recess 84.
The housing 80 of the plug connector 800 is integrally molded with a plurality of terminals 60 of the same shape in an L shape arranged in 2 rows in the longitudinal direction (Y-axis direction) at equal intervals, and can hold the plurality of terminals 60. The support portion 82 extending outward in the short-side direction (X-axis direction) from the side wall portion 83 can support the portion of the L-shaped terminal 60 from the bent portion to the end portion 67. The terminal 60 is soldered to a substrate (not shown) via a mounting portion 61. When the mounting portion 61 is mounted on the substrate by soldering, the inclined portion 81 as the inclined portion of the support portion 82 can prevent the solder from being transferred from the mounting portion 61 to the inside having the fitting recess 84 (see fig. 13). The terminal 60 can be brought into contact with the contact portion 56 (see fig. 13) of the target terminal 50 through the contact portion 62.
Fig. 12 is a side view of the receptacle connector and the plug connector shown in fig. 11 as viewed from the short side direction, and lines a-a and B-B in fig. 12 indicate cut positions of the cross-sectional views shown in fig. 13 and 14. Fig. 13 is a sectional view of the receptacle connector 700 and the plug connector 800, taken along line a-a in fig. 12, of a portion of the terminals 50 included in the receptacle connector 700 and a portion of the terminals 60 included in the plug connector 800. Fig. 14 is a sectional view of receptacle connector 700 and plug connector 800 taken along line B-B in fig. 12, where cut-out portion 71 of housing 70 of receptacle connector 700 and side wall portion 83 of housing 80 of plug connector 800 are partially cut.
When referring to the sectional view shown in fig. 13 and the sectional view shown in fig. 14, the 2 terminals 50 of the receptacle connector 700 are held by the housing 70 so as to be relatively bilaterally symmetrical about the fitting projection 72. The 2 terminals 60 of the plug connector 800 are held by the housing 60 so as to be symmetrical with respect to each other about the fitting recess 84.
The inner leg 51 of each of the 2 terminals 50 is supported on the surface opposite to the surface having the contact portion 52 by the side surface of the fitting projection 72 provided at the central portion of the housing 70. The outer leg 55 of the terminal 50 has a support surface 57 facing outward in the lateral direction (X-axis direction) and supported by the side wall 73. The 2 terminals 60 are supported by covering the bent portions between the mounting portions 61 and the embedded portions 64 with resin.
The contact portion 56 may have a recess in at least a part of a surface facing the contact portion 51. As shown in fig. 13, the contact portion 56 of the terminal 50 may include a contact recess 58 having a concave surface. In the case where the contact recess 58 is provided with a projection (not shown) projecting from the surface of the contact portion 62 of the terminal 60, the contact recess 58 can be locked with the projection on the contact portion 62 when the connector is fitted. The surface of the contact portion 56 is coplanar with the surface of the side wall portion 63.
The housing 70 may include a covering portion 77 filled with resin and covering the fitted portion 53 between the fitting convex portion 72 and the side wall portion 73. The covering portion 77 covers the embedded portion 53 without a gap by not covering the contact portion 56, the contact recess 58, and the contact portion 52, whereby the terminal 50 is firmly fixed to the housing 70. The fitted portion 53 is a curved portion between the inner leg 51 and the outer leg 55, and has a mounting portion 54 for mounting to a board by soldering or the like on a surface opposite to a surface (i.e., a surface on the substrate side (Z1 side)) for receiving the terminal 60 of the plug connector 800 as a target connector.
The side wall portion 73 is provided with the thin portion 74 on the outer side in the short side direction (X-axis direction), and is configured to be easily expanded outward. When the fitting tip portion 66 of the terminal 60 is made to enter the fitted portion 53 of the terminal 50, the outer leg portion 55 of the terminal 50 is pressed outward in the short direction (X-axis direction) and deformed because the outer leg portion 55 has elasticity. In other words, the lateral leg 55 can be displaced in a direction away from the medial leg 51. At this time, the side wall portion 73 including the thin portion 74 is also pressed by the support surface 57 of the outer leg portion 55, and is deformed to expand outward in the short direction (X-axis direction). Thus, the thin portion 74 can promote deformation of the side wall portion 73 at the time of fitting of the connector.
Fig. 15 is a view of the receptacle connector and the plug connector shown in fig. 10 as viewed from the substrate side (Z1 side) of the receptacle connector. The housing 70 is arranged for each longitudinal direction (Y-axis direction) of the terminal 50, and has a groove portion 76 that exposes the mounting portion 54 of the terminal 50 on the substrate-side surface (bottom surface). When the connector 700 is mounted on a substrate, the groove portion 76 can cover the periphery of the bent mounting portion 54 without a gap so that solder does not enter the housing 70 from between the mounting portion 54 and the groove portion 76.
As described above, according to the present invention, in each of the exemplary embodiments, the mounting portion which is conventionally provided at a position distant from the fitted portion of the terminal in the short direction (X-axis direction) of the connector is provided on the surface of the fitted portion on the substrate side, and thus the width in the short direction can be reduced to downsize the connector. The embodiments of the present invention are not independent, and can be combined and appropriately implemented.
[ industrial applicability ]
The connector according to the present invention can be used for connecting boards by flat cables in electronic devices such as smart phones and mobile phones that perform high-speed transmission of electric signals.
