Electrical connector for circuit board and electrical connector assembly

Abstract

The present invention relates to an electrical connector for a circuit board and an electrical connector assembly. A housing has a plug-in / out direction limiting portion (21C) within the range of a terminal arrangement wall (21A) in the terminal arrangement direction (X) for determining the maximum depth position of a mating connector in the connector insertion / removal direction (Z), and a tilt limiting portion (12A) outside the range of the terminal arrangement wall in the terminal arrangement direction, which is spaced apart from a corresponding portion of the mating connector in the connector insertion / removal direction (Z) relative to the mating connector at the maximum depth position. When the mating connector is removed, if the mating connector is tilted so that one end portion of the mating connector in the terminal arrangement direction is lifted more than the other end portion in the connector insertion / removal direction, the other end portion of the mating connector abuts against the tilt limiting portion in the connector insertion / removal direction, thereby limiting the mating connector from tilting by more than a predetermined angle.

Description

Technical Field

[0001] The present invention relates to an electric connector for a circuit substrate and an electric connector assembly. Background Art

[0002] As an electrical connector for a circuit substrate, which is mounted on a circuit substrate and allows a target connector to be plugged in and out in a direction perpendicular to the mounting surface of the circuit substrate as a connector plugging and unplugging direction, there is known an electrical connector of the form disclosed in Patent Document 1. In Patent Document 1, a second connector as a target connector is connected to a first connector as an electrical connector for a circuit substrate. The first connector comprises: a terminal having a connection portion formed with a soldered connection to the mounting surface of the circuit substrate and a contact portion connected to the second connector; and a housing extending in a direction parallel to the mounting surface of the circuit substrate as a longitudinal direction and arranging and holding the terminals in the longitudinal direction as a terminal arrangement direction, the housing having an island-shaped terminal arrangement wall (referred to as an "island-shaped portion" in Patent Document 1) for arranging and holding the contact portions of the terminals.

[0003] The housing of the first connector has a first circumferential wall portion around the island-shaped terminal arrangement wall, forming an annular space between the first circumferential wall portion and the terminal arrangement wall. The cylindrical second circumferential wall portion of the second connector enters the annular space downward. The terminal arrangement wall has a recessed portion formed downward and tilted inward in the terminal arrangement direction on the lower half of the end face in the terminal arrangement direction. This recess allows the second circumferential wall portion of the second connector to tilt so that one end side in the terminal arrangement direction is located above the other end side (in the direction of pulling out the second connector) when the second connector is pulled out. That is, the lower part of the end wall portion on the other end side of the second circumferential wall portion of the second connector is accommodated toward the above-mentioned recessed portion when the second connector is tilted as described above. The lower end of the end wall on the other end side of the second circumferential wall portion of the second connector abuts against the bottom surface of the above-mentioned annular space, acting as a fulcrum during the above-mentioned tilting.

[0004] Patent Document 1: Japanese Patent Application Laid-Open No. 2019-192576

[0005] Connectors are often required to be miniaturized in the longitudinal direction of the connector. In Patent Document 1, the end walls of the first peripheral wall portion of the first connector and the second peripheral wall portion of the second connector are also made thinner. Therefore, when the second connector is pulled out and tilted to abut against the recess obliquely formed in the terminal arrangement wall of the first connector, the inner surface of the lower portion of the end wall of the second connector receives a large force from the end surface of the terminal arrangement wall of the first connector (the inner wall surface of the aforementioned recess) along the longitudinal direction of the connector (the terminal arrangement direction), that is, the thickness direction of the end wall. In addition, before the inclination angle of the second connector reaches its maximum, the inner surface of the end wall of the first peripheral wall portion of the first connector often receives a large force from the outer surface of the end wall of the second connector along the longitudinal direction of the connector. These forces in the longitudinal direction of the connector generate bending stress on the thin end wall, which may result in damage to the end wall. Summary of the Invention

[0006] The present invention is completed in view of the above situation, and its subject is to provide an electric connector for a circuit substrate and a connector assembly having the electric connector for a circuit substrate and a target connector. The above electric connector for a circuit substrate allows the target connector to tilt and prevents the target connector from tilting to become larger than a specified angle, thereby making it less likely to cause damage to the shell.

[0007] According to the present invention, the above-mentioned problems are solved by the following electric connector for a circuit board and an electric connector assembly including the electric connector for a circuit board and a mating connector.

[0008] <Electrical connectors for circuit boards>

[0009] The electric connector for a circuit substrate involved in the present invention is an electric connector that is installed on a circuit substrate and uses a direction at right angles to the mounting surface of the circuit substrate as a connector plugging and unplugging direction for an object connector. It comprises: a terminal, which is formed with a connecting portion that is soldered and mounted on the mounting surface of the above-mentioned circuit substrate and a contact portion that is connected to the object connector; and a shell, which arranges and holds the above-mentioned terminals in a direction parallel to the mounting surface of the above-mentioned circuit substrate as a terminal arrangement direction, and the above-mentioned shell has a terminal arrangement wall that arranges and holds the contact portions of the above-mentioned terminals.

[0010] In the above-mentioned electrical connector for a circuit board, the present invention is characterized in that the housing includes a plugging / extraction direction restricting portion, the plugging / extraction direction restricting portion being provided within the range of the terminal arrangement wall in the terminal arrangement direction, abutting against the mating connector in the connector plugging / extraction direction, and determining the maximum mating depth position of the mating connector. The housing or a component mounted on the housing includes a tilt restricting portion, the tilt restricting portion being provided outside the range of the terminal arrangement wall in the terminal arrangement direction, spaced apart from a corresponding portion of the mating connector in the connector plugging / extraction direction relative to the mating connector at the maximum mating depth position. The tilt restricting portion includes a first end tilt restricting portion and a second end tilt restricting portion, respectively located at opposite ends in the terminal arrangement direction. When the mating connector is removed, if the mating connector is tilted such that one end portion of the mating connector in the terminal arrangement direction is lifted more than the other end portion from the first end tilt restricting portion in the connector plugging / extraction direction, the other end portion of the mating connector abuts against the second end tilt restricting portion in the connector plugging / extraction direction, thereby restricting the mating connector from tilting by more than a predetermined angle.

[0011] In this circuit board electrical connector, when mated with the mating connector in a standard position and posture, the mating connector is not tilted but mated at right angles to the circuit board, and is at its maximum mating depth, where the mating connector abuts the insertion / extraction direction restricting portion. In this position, a gap is formed in the connector insertion / extraction direction between the tilt restricting portions located at both ends of the circuit board electrical connector in the terminal arrangement direction, namely, the one-end tilt restricting portion and the other-end tilt restricting portion, and the corresponding portions of the mating connector.

[0012] When unplugging the object connector, it is preferred to pull the object connector in a direction perpendicular to the circuit board. However, in practice, most of the time, the object connector is pulled up while being tilted so that one end side portion in the terminal arrangement direction is raised more than the other end side portion. This operation makes unplugging easier.

[0013] When the mating connector is tilted and then pulled upward for removal as described above, in the present invention, the mating connector is permitted to tilt by the gap in the connector insertion / removal direction between the corresponding portion of the mating connector and the tilt limiting portion of the circuit board electrical connector, and the maximum amount of tilt is limited by the mating connector abutting against the tilt limiting portion. Specifically, when the mating connector is removed, if one end portion of the mating connector in the terminal arrangement direction is tilted more than the other end portion in the connector insertion / removal direction from the one-end tilt limiting portion, the other end portion of the mating connector abuts against the other-end tilt limiting portion in the connector insertion / removal direction, thereby limiting the mating connector from tilting beyond a predetermined angle.

[0014] The direction in which this abutment force of the mating connector against the tilt limiting portion is generated is the connector insertion / removal direction. In an electrical connector for a circuit board, the end portion of the housing mating with the mating connector in the terminal arrangement direction is typically thicker in the connector insertion / removal direction than in the terminal arrangement direction, resulting in increased strength. Therefore, in the present invention, damage to the tilt limiting portion of the housing caused by abutment force in the connector insertion / removal direction is less likely to occur.

[0015] Assuming that the ends of the electrical connector for the circuit substrate and the object connector in the terminal arrangement direction have portions facing each other in the same direction, before the inclined end of the object connector abuts against the end of the electrical connector for the circuit substrate in the terminal arrangement direction, a gap is set in advance between the end of the electrical connector for the circuit substrate and the end of the object connector in the terminal arrangement direction so that the above-mentioned inclination limiting portion can be used to prevent the object connector from tilting more than a specified angle, thereby avoiding these ends from abutting against each other in the terminal arrangement direction.

[0016] In the present invention, the housing has two terminal arrangement walls parallel to each other and end walls connecting the two ends thereof, a peripheral wall is formed by the two terminal arrangement walls and the two end walls, a receiving space for receiving the object connector is formed within the peripheral wall, and the inner wall surface of the end wall forms an inclined surface in which the distance between the two end walls increases toward the side of the object connector in the connector plugging and unplugging direction, and the inclined surface can be used to allow the object connector to tilt until it abuts against the above-mentioned tilt limiting portion.

[0017] Thus, even if the housing of the circuit board connector has an end wall, the inner surface of the end wall is formed with two inclined surfaces whose distance between the end walls increases toward the mating connector in the connector insertion and removal direction. Therefore, these inclined surfaces allow the mating connector to tilt until the mating connector abuts the tilt restricting portion. Therefore, the provision of the end wall in the housing of the circuit board connector does not hinder the tilting of the mating connector.

[0018] In the present invention, the tilt limiting portion is preferably located outward of the mating connector in the terminal arrangement direction. Thus, when the mating connector is tilted, one end portion and the other end portion of the mating connector are more likely to be located within the range of the tilt limiting portion in the terminal arrangement direction. As the mating connector tilts further, the tilt limiting portion can effectively limit the tilt of the mating connector.

[0019] In the present invention, the tilt limiting portion may be formed on a metal component mounted on the housing. Forming the tilt limiting portion on the metal component improves its strength compared to forming the tilt limiting portion on a resin, a common material for the housing, thereby more effectively limiting the tilt of the mating connector.

[0020] <Connector assembly>

[0021] The electrical connector assembly involved in the present invention is characterized in that it has the above-mentioned circuit board electrical connector and a target connector that is mated and connected to the circuit board electrical connector, and the target connector has an inclined restricted portion that is opposite to the inclined restricted portion of the above-mentioned circuit board electrical connector in the connector insertion and removal direction.

[0022] According to the present invention, when the object connector is tilted and then pulled up to be removed, the object connector is allowed to tilt due to the gap in the connector plugging and unplugging direction formed between the object connector and the tilt limiting portion of the circuit board electrical connector, and its maximum tilting amount is limited by the object connector abutting against the tilt limiting portion. That is, the direction in which the abutting force of the object connector relative to the tilt limiting portion is generated is the connector plugging and unplugging direction. In the circuit board electrical connector, the end of the housing that mates with the object connector in the terminal arrangement direction is usually thicker in the connector plugging and unplugging direction than in the terminal arrangement direction, and therefore has high strength. Therefore, in the present invention, damage to the tilt limiting portion of the housing caused by the abutting force in the connector plugging and unplugging direction is not easily generated.

DETAILED DESCRIPTION

[0030] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0031] Figure 1 1 is a perspective view showing the appearance of the connector I and the mating connector II according to the present embodiment before being fitted together. Figure 2 Yes Figure 1 Cross-sectional view showing the terminal positions of connector I and mating connector II. Figure 2 yes Figure 1 The cross-sectional view of connector I and target connector II on the YZ plane is shown in the figure. Figure 3 (A) means Figure 1 A perspective view of a connector and each of a plurality of terminals of a mating connector. Figure 3 (B) means Figure 1 A perspective view of a connecting component on one side of a connector.

[0032] exist Figure 1 In the embodiment, connector I and counterpart connector II are electrical connectors for circuit boards, each mounted on a different circuit board (not shown), and are mated and connected with the surfaces of the circuit boards parallel to each other. In this embodiment, connector I is configured as a so-called receptacle connector having female terminals (terminals 30 described later), and connector II is configured as a so-called plug connector having male terminals (counterpart terminals 60 described later). In this embodiment, to facilitate understanding of directionality, the terminal arrangement direction parallel to the surface of the circuit board is designated as X (one side is X1, the other side is X2), the connector width direction parallel to the surface of the circuit board and perpendicular to the terminal arrangement direction X is designated as Y (one side is Y1, the other side is Y2), and the vertical direction perpendicular to both X and Y is designated as Z (upper is Z1, lower is Z2).

[0033] With the vertical direction Z as the connector insertion and removal direction, the counterpart connector II is fitted and connected to the connector I mounted on the circuit board (not shown) from the upper side Z1, that is, toward the lower side Z2.

[0034] The structures of the connector I and the counterpart connector II are described below in sequence.

[0035] like Figure 1 and Figure 2 As shown, the connector 1 of this embodiment comprises a housing (fixed housing 10 and movable housing 20, described later) made of an electrically insulating material such as resin, metal terminals 30, and a metal connecting member 40. The connector 1 has a generally rectangular shape with the terminal arrangement direction X as its longitudinal direction. It is disposed on a circuit board (not shown), with the terminals 30 and connecting member 40 soldered to corresponding portions of the circuit board. In this embodiment, the connector 1 is symmetrical in both the terminal arrangement direction X and the connector width direction Y.

[0036] The housing comprises two fixed housings 10 fixed to the circuit board via terminals 30 and connecting members 40, and a movable housing 20 movable relative to the fixed housings 10. The fixed housings 10 and movable housing 20 are manufactured as independent components. One fixed housing 10 is provided on either side of the movable housing 20 in the connector width direction Y, namely, on the Y1 side and the Y2 side. These fixed housings 10 are independent components, each located at a position separated from the movable housing 20 in the connector width direction Y and extending along the terminal arrangement direction X.

[0037] like Figure 1 As shown, each fixed housing 10 includes a relatively thin, rod-shaped intermediate portion 11 extending within the arrangement range of the terminals 30 in the terminal arrangement direction X, and connected portions 12 located on either side of the intermediate portion 11 in the terminal arrangement direction X and formed higher than the intermediate portion 11 in the vertical direction Z. In other words, each connected portion 12 forms an end portion of the fixed housing 10 in the terminal arrangement direction X, and its upper surface is located above the upper surface of the intermediate portion 11.

[0038] like Figure 2 As shown, the cross-section of the intermediate portion 11, which is perpendicular to the terminal arrangement direction X, is generally crank-shaped, formed by connecting an upper portion 11A located inwardly in the connector width direction Y and projecting upwardly (Z1), and a lower portion 11B located outwardly in the connector width direction Y and projecting downwardly (Z2). The upper portion 11A and the lower portion 11B of the intermediate portion 11 form a fixed-side retaining portion that is integrally molded (insert-molded) to retain a fixed-side connecting portion 34, described later, which forms one end portion (the lower end portion in the figure) of the terminal 30.

[0039] The dimension of the connected portion 12 in the vertical direction Z is larger than the dimension in the terminal arrangement direction X. The upper portion of the connected portion 12 is formed with a tilt limiting portion 12A for limiting the tilt of the target connector II greater than a predetermined angle. As will be described later, when the target connector II is pulled out, the tilt limiting portion 12A contacts the target connector II with the flat upper surface of the tilt limiting portion 12A when the target connector II tilts as the target connector II rotates around the Y axis extending in the connector width direction Y, thereby limiting the tilt of the target connector II greater than a predetermined angle (see Figure 4 and Figure 5 (B)). The connected portion 12 and the tilt restricting portion 12A are in the connector mating state at the standard mating position (see Figure 5 (A)) is located outward of the outer end surface (a surface perpendicular to the terminal arrangement direction X) of the end wall 50B of the mating connector II in the terminal arrangement direction X. In this embodiment, the tilt restricting portion 12A located on the X1 side in the terminal arrangement direction X is referred to as the "one end side tilt restricting portion 12A," and the tilt restricting portion 12A located on the X2 side is referred to as the "other end side tilt restricting portion 12A," as needed. When the distinction between the two is not necessary, they are collectively referred to simply as the "tilt restricting portion 12A."

[0040] like Figure 1 and Figure 2 As shown, the movable housing 20 includes a fitting portion 21 constituting an upper half and a support portion 22 constituting a lower half.

[0041] like Figure 1 As shown, the fitting portion 21 is in the shape of a square tube with a bottom opening upward Z1, and has two side walls 21A extending along the terminal arrangement direction X as terminal arrangement walls, two end walls 21B extending along the connector width direction Y and connecting the two end portions of the two side walls 21A, and a bottom wall 21C (see FIG. 1 ) that closes the lower portion of the peripheral wall formed by the two side walls 21A and the two end walls 21B. Figure 2 ).like Figure 2 As shown, the fitting portion 21 holds the terminal 30 with the side walls 21A and the bottom wall 21C. The space surrounded by the peripheral wall and the bottom wall 21C and open upward forms a receiving space 23 for receiving the central wall 50D (described later) as a corresponding portion of the mating connector II from above Z1.

[0042] like Figure 5 As shown in FIG. 1A , the inner surface of the end wall 21B is oriented upward (Z1) and tilted outward in the terminal arrangement direction X, forming an inclined surface 21B-1 in which the distance between the inner surfaces of the two end walls 21B (the distance in the terminal arrangement direction X) increases as the distance increases upward. As will be described later, the end wall 21B, due to the inclined surface 21B-1, allows the mating connector II to tilt until it abuts against the tilt limiting portion 12A of the fixed housing 10.

[0043] The bottom wall 21C is located within the same range as the side wall 21A in the terminal arrangement direction X, and its top surface is formed as a flat surface. When the connectors are mated, the bottom wall 21C abuts against the mating connector II from above (Z1) in the vertical direction Z, and functions as a plugging and unplugging direction restrictor that determines the maximum mating depth of the mating connector II. Specifically, when the mating connector II is mated to the connector I without tilting relative to the vertical direction Z, and the center wall 50D (described later) of the mating connector II is inserted into the receiving space 23 from above, the lower end surface of the center wall 50D contacts and abuts against the top surface of the bottom wall 21C, thereby determining the maximum mating depth of the mating connector II.

[0044] The support portion 22 includes a longitudinal central wall portion 22A and a longitudinal end wall portion 22B extending downwardly from the lower surface of the bottom wall 21C toward Z2, and a movable restricted portion 22C extending outwardly from the lower end of the longitudinal end wall portion 22B in the terminal arrangement direction X. The lower ends of the longitudinal central wall portion 22A and the longitudinal end wall portion 22B of the support portion 22 are located near the surface of a circuit board (not shown) but are not fixed to the circuit board. When subjected to external force, the terminals 30 elastically deform, thereby allowing the movable housing 20 as a whole to move in the terminal arrangement direction X, the connector width direction Y, and the vertical direction Z.

[0045] The longitudinal center wall portion 22A is located at the center of the bottom wall 21C in the connector width direction Y, extending downwardly Z2 from the lower surface of the bottom wall 21C, and extending over the entire length of the receiving space 23 in the terminal arrangement direction X. The longitudinal end wall portions 22B are located at the same positions in the terminal arrangement direction X as the end walls 21B of the fitting portion 21. In other words, the longitudinal end wall portions 22B are integrally formed with the longitudinal center wall portion 22A at both ends of the longitudinal center wall portion 22A in the same direction X, and extend in the connector width direction Y over the same range as the end walls 21B.

[0046] As described above, the movable restricted portion 22C extends outward from the lower end portion of the vertical end wall portion 22B in the terminal arrangement direction X. Figure 1 and Figure 5 As shown in FIG. (A), the movable restricted portion 22C is located below the intermediate bridge portion 41 of the connecting member 40 described later. The upper surface of the movable restricted portion 22C is in contact with the lower surface of the intermediate bridge portion 41 (see FIG. Figure 5 (A)). As a result, the upward movement of the movable housing 20 in the Z1 direction is restricted by the movable restricted portion 22C contacting the intermediate bridge portion 41 from below. Alternatively, the movable restricted portion 22C may be located at a position spaced apart from the intermediate bridge portion 41 in the vertical direction Z. In this case, the upward movement of the movable housing 20 in the Z1 direction is permitted only to the extent of the aforementioned space.

[0047] like Figure 2 As shown, the space surrounded by the bottom wall 21C, the longitudinal central wall portion 22A and the longitudinal end wall portion 22B is open toward the lower side Z2 and the outer side of the connector width direction Y, forming a lateral open space 24 for accommodating the later-described inner straight portion 33A and the middle straight portion 33C of the terminal 30.

[0048] like Figure 2 and Figure 3 As shown in (A), the terminal 30 is made by bending a metal flat strip in the direction of its plate thickness, and the width of the strip at right angles to the plate thickness is used as the terminal width. Figure 3 As shown in (A), the terminal width of the contact portion 32 described later is slightly wider than the terminal width of other parts, and the terminal width of the other parts is substantially the same width over the entire length. Figure 2 As shown, when the connector 1 is viewed along the terminal arrangement direction X, the terminal 30 includes: a connecting portion 31 formed at one end portion located on the lower Z2 side, a contact portion 32 formed at the other end portion located on the upper Z1 side, an elastic portion 33 extending in a substantially horizontal S-shape between the connecting portion 31 and the contact portion 32, a fixed-side connecting portion 34 connecting the connecting portion 31 and the elastic portion 33, and a movable-side connecting portion 35 connecting the contact portion 32 and the elastic portion 33 (see also FIG. 1 ). Figure 3 (A) The terminals 30 are symmetrically arranged in pairs in the connector width direction Y, and a plurality of such pairs are arranged in the terminal arrangement direction X.

[0049] like Figure 2 As shown, the connection portion 31 protrudes from the bottom surface of the middle portion 11 of the fixed housing 10 and extends outward along this bottom surface in the connector width direction Y. When the connector 1 is placed on the upper surface of a circuit board (not shown), the connection portion 31 is soldered to the corresponding circuit portion of the circuit board. The fixed-side connecting portion 34 extends upward Z1 from the inner end of the connection portion 31 in the connector width direction Y in a crank-like shape and is retained by the middle portion 11 of the fixed housing 10 through integral molding. A portion of the lower surface of the fixed-side connecting portion 34 is exposed due to support by the mold during integral molding.

[0050] like Figure 2As shown, the contact portion 32 extends linearly along the inner surface of the side wall 21A of the movable housing 20. Its upper end portion forms an inverted U-shaped upper curved portion 32A that curves outward in the connector width direction Y. The front end of the upper curved portion 32A is completely embedded within the side wall 21A, with the remainder of the portion remaining embedded within the side wall 21A, with only the upper surface exposed. The upper surface of the upper curved portion 32A, particularly the inner upper surface that is located inward in the connector width direction Y, protrudes slightly from the upper surface of the side wall 21A to form a surface approximately flush with the side wall 21A, serving as a guide surface for the mating connector II.

[0051] The linear portion of the contact portion 32, that is, the portion extending along the inner side surface of the side wall 21A, is embedded in the side wall 21A, with only the inner surface toward the receiving space 23 exposed. The inner surface of the linear portion protrudes slightly beyond the inner side surface of the side wall 21A and forms a contact surface with the mating terminal 60 of the mating connector II.

[0052] The movable side connecting portion 35 extends downward Z2 from the lower end of the contact portion 32 in a crank shape and is held by the bottom wall 21C of the movable housing 20 by integral molding. A portion of the lower surface of the movable side connecting portion 35 is exposed due to support by the mold during integral molding.

[0053] like Figure 2 As shown, the elastic portion 33 is formed into a shape that is curved in a generally horizontal S-shape when viewed from the terminal arrangement direction X, and connects the upper end of the fixed-side connecting portion 34 to the lower end of the movable-side connecting portion 35. The elastic portion 33 includes an inner linear portion 33A located on the inside in the connector width direction Y, an outer linear portion 33B located on the outside, an intermediate linear portion 33C located between these portions, a lower curved portion 33D connecting the inner linear portion 33A and the intermediate linear portion 33C at their lower ends, and an upper curved portion 33E connecting the intermediate linear portion 33C and the outer linear portion 33B at their upper ends.

[0054] When the terminal 30 is subjected to external force, the elastic portion 33 of this shape can be elastically displaced (elastically deformed) as a whole in the terminal arrangement direction X, the connector width direction Y, and the vertical direction Z. Therefore, when the movable housing 20 is positioned relative to the fixed housing 10, for example, in the connector width direction Y, and is offset from the standard mating position, the elastic displacement of the elastic portion 33 in the connector width direction Y is used to absorb this offset, thereby achieving so-called floating. In this case, if the movable housing 20 is offset, for example, to the Y1 side in the connector width direction Y, the elastic portion 33 of the terminal 30 located on the Y1 side is elastically displaced so as to be compressed in the connector width direction Y, while the elastic portion 33 of the terminal 30 located on the Y2 side is elastically displaced so as to be expanded in the same direction Y.

[0055] like Figure 3 As shown in (B), the connecting member 40 is formed in a form in which a metal strip-shaped member is bent in the plate thickness direction. Figure 3 (B) shows the connecting member 40 located on the X1 side of the terminal arrangement direction X, of the two connecting members 40 provided in the connector 1. The connecting member 40 located on the X2 side is Figure 3 The connecting member 40 shown in (B) is provided in a symmetrical posture in the terminal arrangement direction X.

[0056] The connecting component 40 is arranged on the outer side of the lower part of the movable shell 20 in the terminal arrangement direction X, and has: an intermediate bridge portion 41 parallel to the surface of the circuit substrate and extending along the connector width direction Y, a foot-shaped retained portion 42 bent at both ends of the intermediate bridge portion 41 in the connector width direction Y and extending toward the lower side Z2, and a fixed portion 43 bent at the lower end of the retained portion 42 and extending toward the outside in the connector width direction Y.

[0057] The intermediate bridge portion 41 is arranged with its plate thickness direction as the vertical direction Z, and extends across the range between the connected portions 12 of the two fixed housings 10 in the connector width direction Y. Furthermore, the intermediate bridge portion 41 is located directly above the movable restricted portion 22C of the movable housing 20 and is capable of abutting against the movable restricted portion 22C from above, functioning as a restricting portion that restricts the upward movement Z1 of the movable restricted portion 22C and, therefore, the movable housing 20.

[0058] The held portion 42 is integrally molded and embedded within the connected portion 12 of the fixed housing 10. The fixed portion 43 protrudes from and extends along the bottom surface of the connected portion 12 of the fixed housing 10. When the connector 1 is placed on the upper surface of a circuit board (not shown), the fixed portion 43 is fixed to a corresponding portion of the circuit board by soldering.

[0059] The connecting member 40 is held by the connected portions 12 of the two fixed housings 10, whereby these fixed housings 10 are connected to each other via the connecting member 40. In this embodiment, when the connector 1 is viewed along the up-down direction Z, the fixed housing 10 and the connecting member 40 cooperate to form a square frame shape surrounding the lower portion of the movable housing 20. Advantages of using the connecting member 40 to connect the two separately arranged fixed housings 10 include, in addition to strengthening the fixation of the two fixed housings 10 to the circuit substrate, miniaturization of the terminal arrangement direction X of the connector 1 and facilitation of manufacturing the fixed housings 10. Furthermore, as described above, when the intermediate bridge portion 41 of the connecting member 40 functions as a limiting portion that limits the movement of the movable housing 20 in the upward direction Z1, since the connecting member 40 is made of metal, advantages such as high strength and large limiting capacity can also be cited.

[0060] like Figure 1 As shown, the counterpart connector II includes a counterpart housing 50 made of an electrically insulating material such as resin and a counterpart terminal 60 made of a metal plate held by the counterpart housing 50. Figure 1 In FIG. 1 , the object connector II is shown facing downward Z2 and is connected to the connector I, and is mounted on the bottom side of the circuit board (not shown). Therefore, the fitting side of the object connector II faces downward Z2, so Figure 1 Not shown.

[0061] like Figure 1 As shown, the counterpart housing 50 has a rectangular parallelepiped shape with the terminal arrangement direction X as its longitudinal direction. The counterpart housing 50 comprises two side walls 50A extending in the terminal arrangement direction X, two end walls 50B extending in the connector width direction Y and connecting the two ends of the two side walls 50A, and a peripheral wall formed by the two side walls 50A and the two end walls 50B. Figure 1 The bottom wall 50C with a closed upper portion, and the central wall 50D extending downward from the bottom wall 50C in the peripheral wall (see Figure 2 and Figure 5 (A) Figure 5 (B)). The central wall 50D is in the shape of a plate extending in the terminal arrangement direction X at the central position in the connector width direction Y. It is surrounded by the peripheral wall, bottom wall 50C and central wall 50D and extends toward Figure 1 The annular space opened at the lower Z2 in the middle forms a mating side receiving space 51 for receiving the peripheral wall of the fitting portion 21 of the connector 1 from below (see Figure 2 and Figure 5 (A) Figure 5 (B)).

[0062] The dimension of the end wall 50B in the vertical direction Z is larger than the dimension in the terminal arrangement direction X. Figure 1 As shown, the lower end of the end wall 50B protrudes downward Z2 from the lower end of the side wall 50A to form an inclined restricted portion 50B-1 (see also FIG. Figure 5 (A) Figure 5 (B)). As will be described later, when the connector is pulled out, when the mating connector II is tilted relative to the vertical direction Z, that is, when it is tilted relative to the direction of rotation about the axis in the connector width direction Y, the tilt restricted portion 50B-1 abuts against the upper surface of the tilt restricting portion 12A of the connector I from above Z1, and tilting greater than a predetermined angle is restricted (see Figure 4 、 Figure 5 (B)). In this embodiment, as needed, the tilted restricted portion 50B-1 located on the X1 side in the terminal arrangement direction X is referred to as the "one end tilted restricted portion 50B-1," and the tilted restricted portion 50B-1 located on the X2 side is referred to as the "other end tilted restricted portion 50B-1." If there is no need to distinguish between the two, they are collectively referred to as simply the "tilted restricted portion 50B-1."

[0063] The lower end portion of the central wall 50D forms a portion 50D-1 in which the insertion and removal directions are restricted. Figure 5 As shown in FIG. 1A , when the mating connector II is brought downwardly toward Z2 without tilting relative to the vertical direction Z to the standard mating position with the connector I, the insertion / extraction direction restricted portion 50D-1 abuts against the bottom wall 21C, which serves as the insertion / extraction direction restricting portion of the connector I. As a result, the lower surface of the insertion / extraction direction restricted portion 50D-1 contacts the upper surface of the bottom wall 21C, and the maximum mating depth position of the mating connector II is determined.

[0064] The counterpart housing 50 is located in the standard mating position with the connector 1 (see Figure 5 (A)) When the housing of the connector 1 is used as described above, the housing has the following dimensional relationships (1) to (3) in the terminal arrangement direction X and the up-down direction Z.

[0065] (1) The counterpart housing 50 of the counterpart connector II is as follows Figure 5 As shown in FIG. 1A , the distance L2 between the outer surfaces of the end walls 50B on both sides in the terminal arrangement direction X is smaller than the distance L1 between the outer ends of the connected portions 12 at both ends of the fixed housing 10 of the connector 1 in the terminal arrangement direction X. The end wall 50B of the mating housing 50 is positioned within the range of the connected portion 12 in the terminal arrangement direction X. That is, in the terminal arrangement direction X, the inclined restricted portion 50B-1 forming the lower end of the end wall 50B is positioned within the range of the inclined restricted portion 12A forming the upper portion of the connected portion 12.

[0066] (2) Figure 5As shown in Figure (A), the end wall 50B of the mating housing 50 of the mating connector II protrudes downward Z2 by a distance corresponding to h1, beyond the insertion / extraction direction restricting portion 50D-1 of the central wall 50D. In other words, the insertion / extraction direction restricting portion 50D-1 is recessed upward Z1 by a distance corresponding to h1, beyond the lower end of the end wall 50B. Furthermore, a gap h2 is formed in the vertical direction Z between the tilt restricting portion 50B-1 of the end wall 50B and the tilt restricting portion 12A of the connected portion 12 of the fixed housing 10 of the connector I.

[0067] (3) A gap h3 is formed between the bottom surface (upper surface in FIG. 5A ) of the mating side receiving space 51 in the mating housing 50 of the mating connector II and the end wall 21B of the movable housing 20 of the connector I in the vertical direction Z.

[0068] like Figure 2 As shown, the target housing 50 is formed with a terminal groove 52 for accommodating the target terminal 60 described later. As described later, the target terminal 60 is made by punching the surface of a metal plate in the direction of the plate thickness. Figure 2 The terminal is received in the terminal groove 52 in a posture parallel to the paper surface (YZ plane).

[0069] like Figure 2 As shown, the terminal groove 52 has an outer receiving groove 52A, a press-in groove 52B and an inner receiving groove 52C. The outer receiving groove 52A extends from the middle position of the side wall 50A to the bottom surface of the bottom wall 50C in the vertical direction Z. Figure 2 The press groove 52B is formed to be open to the inner side and the upper side Z1 in the connector width direction Y within the range of the upper surface in the middle. Figure 2 The inner receiving groove 52C is formed in the vertical direction Z from the lower end of the central wall 50D to the bottom surface of the bottom wall 50C (Z2) below the outer receiving groove 52A. Figure 2 The terminal groove 52 is formed to be open to the outside and the upper Z1 in the width direction Y of the connector within the range of the upper surface in the middle. Figure 2 The groove width in a direction perpendicular to the paper surface (terminal arrangement direction X) is substantially equal to the plate thickness of the counterpart terminal 60 .

[0070] As described above, the counterpart terminal 60 is produced by punching out a metal plate in the plate thickness direction (a direction perpendicular to the plate surface) while maintaining the metal plate surface flat (see also FIG. Figure 3 ).like Figure 2As shown, the object terminal 60 has: a straight fixed arm portion 61 extending along the up-down direction Z, an extended arm portion 62 extending from the middle position of the fixed arm portion 61 in the up-down direction Z toward the inner side of the connector width direction Y, a contact arm portion 63 bent from the extended arm portion 62 and extending downward Z2, and a connecting portion 64 extending from the upper end portion of the fixed arm portion 61 toward the outer side of the connector width direction Y.

[0071] like Figure 2 As shown, the upper half of the fixed arm portion 61 is received in the outer receiving groove 52A, and the lower half is held in the press-in groove 52B by being pressed in. A press-in protrusion 61A is formed on the side edge of the lower half of the fixed arm portion 61. When the lower half is pressed from above into the press-in groove 52B to a predetermined position, the press-in protrusion 61A bites into the inner wall surface of the press-in groove 52B and is fixed, thereby preventing the target terminal 60 from falling out.

[0072] The contact arm portion 63 is accommodated in the inner receiving groove 52C except for the contact portion 63A described later. In the present embodiment, the contact arm portion 63 is located at a position with a small gap between it and the inner wall surface of the inner receiving groove 52C in the plate thickness direction (terminal arrangement direction X), and elastic displacement in the connector width direction Y is allowed. A contact portion 63A is provided at the lower end portion of the contact arm portion 63, which protrudes outward in the connector width direction Y and is located in the object side receiving space 51. The contact portion 63A is a portion for contacting the contact portion 32 of the terminal 30 of the above-mentioned connector I, and when the contact arm portion 63 is elastically displaced, the protruding top surface (plate thickness surface) of the contact portion 63A can contact the plate surface of the contact portion 32. When the connector II is arranged on a circuit substrate (not shown), the connecting portion 64 is Figure 2 The upper edge of the circuit board is soldered to the corresponding circuit portion of the circuit board.

[0073] The connector I of the present embodiment described above is used together with the counterpart connector II described above in the following manner.

[0074] First, connector I and mating connector II are each mounted on a corresponding circuit board (not shown). Specifically, connector I is mounted by soldering the connecting portion 31 of terminal 30 to the corresponding circuit portion of the circuit board, and by soldering the fixed portion 43 of connecting member 40 to the corresponding portion of the circuit board. Meanwhile, mating connector II is mounted by soldering the connecting portion 64 of mating terminal 60 to the corresponding circuit portion of another circuit board.

[0075] Next, if Figure 1 and Figure 2 As shown, the object connector II is provided with the object side receiving space 51 (refer to Figure 2) is positioned above the connector I with its opening facing downward Z2, and is in a state before being fitted. Then, the counterpart connector II is lowered without tilting relative to the vertical direction Z. As the counterpart connector II is lowered, the central wall 50D of the counterpart connector II enters the receiving space 23 in the fitting portion 21 of the connector I from above, and the fitting portion 21 of the connector I enters the mating side receiving space 51 of the counterpart connector II from below, and the connector I and the counterpart connector II are brought together. Figure 5 (A) shows the standard fitting position (standard fitting position) and is in the fitted state.

[0076] In this standard mating position, the lower end of the central wall 50D of the mating connector II, that is, the lower surface of the insertion and extraction direction restricted portion 50D-1, abuts against the insertion and extraction direction restricting portion of the mating portion 21 of the connector I, that is, the upper surface of the bottom wall 21C, thereby determining the mating connector II at the maximum depth position (see Figure 5 (A)). In this standard chimeric position, such as Figure 5 As shown in (A), only the insertion and removal direction restriction portion 50D-1 of the target connector II and the bottom wall 21C of the connector I, which serves as the insertion and removal direction restriction portion, abut in the vertical direction Z, and the other parts do not abut. Figure 5 As shown in (A), a gap h3 is formed in the vertical direction Z between the bottom wall 50C of the mating connector II and the end wall 21B of the connector I, and a gap h2 is formed in the vertical direction Z between the tilt restricted portion 50B-1 of the end wall 50B of the mating connector II and the tilt restricting portion 12A of the connector I.

[0077] When such a connector I and the target connector II are in the standard mating position, the contact portion 63A of the target terminal 60 of the target connector I contacts and electrically connects with the contact portion 32 of the terminal 30 of the connector I by means of contact pressure while the contact arm portion 63 is elastically displaced.

[0078] The counterpart connector II is not necessarily limited to being brought to the standard mating position relative to the connector I. For example, when the counterpart connector II is moved from the standard position to the Y1 side ( Figure 2 When the position of the terminal 30 (on the right side) starts to shift toward the connector 1, the movable housing 20 of the connector 1 receives the force from the counterpart housing 50 toward the Y1 side, and the elastic portion 33 of the terminal 30 elastically displaces (elastically deforms), thereby moving toward the Y1 side relative to the fixed housing 10. That is, the elastic displacement of the elastic portion 33 is used to absorb the shift. At this time, Figure 2In the embodiment, the elastic portion 33 of the terminal 30 on the Y1 side is elastically displaced so as to be compressed in the connector width direction Y, while the elastic portion 33 of the terminal 30 on the Y2 side is elastically displaced so as to be expanded in the connector width direction Y. In this way, even if the mating connector II is mated at a position deviated from the standard position, the elastic displacement of the elastic portion 33 can be used to cope with the deviation as long as the deviation is within the allowable range.

[0079] When removing the mating connector II fitted with the connector I from the connector I, the mating connector II can be removed by pulling it straight upward Z1 without tilting it relative to the vertical direction Z. However, sometimes the mating connector II can be removed by tilting it relative to the vertical direction Z. Figure 4 and Figure 5 As shown in (B), the counterpart connector II is often tilted around an axis extending in the connector width direction Y. Figure 4 and Figure 5 (B) shows a state in which one end side portion (X1 side portion) of the counterpart connector II in the terminal arrangement direction X is lifted larger than the other end side portion (X2 side portion).

[0080] Conventionally, when the mating connector is removed from the connector while tilting, a strong contact force in the terminal arrangement direction acts between the end wall of the connector and the end wall of the mating connector at the other end of the terminal arrangement direction. Typically, connectors are required to have a smaller diameter in the terminal arrangement direction, so the end wall in the same direction is often formed thinner. In such cases, the end wall may be damaged by this contact force.

[0081] In this embodiment, if Figure 5 As shown in (A), when the mating connector II is mated with the connector I in the standard mating position, the mating connector II is not tilted with respect to the vertical direction Z, and a gap a is formed between the end surface 50D-2 of the central wall 50D of the mating connector II in the terminal arrangement direction X and the inclined surface 21B-1 of the end wall 21B of the connector I. When the mating connector II is removed, the mating connector II is tilted so that the one end side of the mating connector II is lifted from the one end side tilt restricting portion 12A of the connector I by the inclination restricting portion 50B-1 on the one end side (X1 side) in the terminal arrangement direction X. Figure 5 As shown in (B), the inclination of the mating connector II is allowed by the gap a.

[0082] When the target connector II is tilted at a predetermined angle, Figure 5As shown in (B), at the other end side (X2 side) in the terminal arrangement direction X, the other end side tilt restricted portion 50B-1 of the end wall 50B abuts against the other end side tilt restricted portion 12A in the vertical direction of the connector 1 from above, and the tilting angle greater than the above-mentioned predetermined angle is restricted. In this embodiment, while the other end side tilt restricted portion 50B-1 abuts against the other end side tilt restricted portion 12A, as shown in Figure 5 As shown in FIG. 2B , on the other end side (X2 side) in the terminal arrangement direction X, the end surface 50D-2 of the center wall 50D of the mating connector II contacts and abuts the inclined surface 21B-1 of the end wall 21B of the connector I. In other words, in this embodiment, the contact between the end surface 50D-2 of the center wall 50D and the inclined surface 21B-1 of the end wall 21B also restricts the tilt of the mating connector II. With the other end side tilt restricted portion 50B-1 abutting the other end side tilt restricting portion 12A of the connector I, the mating connector II is removed from the connector I on one end side (X1 side). Then, it can be easily removed by lifting it straight up toward Z1.

[0083] In this embodiment, as described above, the other-end-side tilting restricted portion 50B-1 abuts the other-end-side tilting restricted portion 12A from above, thereby restricting the counterpart connector II from tilting at an angle greater than the aforementioned predetermined angle. Therefore, the abutment force between the other-end-side tilting restricted portion 50B-1 and the other-end-side tilting restricted portion 12A is generated in the vertical direction Z. The connected portion 12 of connector I, on which the other-end-side tilting restricted portion 12A is formed, and the end wall 50B of connector II, on which the other-end-side tilting restricted portion 50B-1 is formed, are larger in the vertical direction Z than in the terminal arrangement direction X, thereby increasing their strength. Therefore, the other-end-side tilting restricted portion 12A and the other-end-side tilting restricted portion 50B-1 can fully resist the aforementioned abutment force generated in the vertical direction Z. As a result, damage to the housing caused by the aforementioned abutment force is less likely to occur.

[0084] In addition, in this embodiment, Figure 5 (A) Figure 5 As shown in (B), the inclination limiting portion 12A of the connector I is located at a position farther outward than the end wall 50B of the target connector II in the terminal arrangement direction X. Therefore, when the target connector II is tilted, the other end side inclination limiting portion 50B-1 of the target connector II is easily located within the range of the other end side inclination limiting portion 12A in the terminal arrangement direction X. The inclination of the target connector II can be well limited by the other end side inclination limiting portion 50B-1.

[0085] In this embodiment, the tilt limiting portion 12A is formed in the fixed housing 10, but alternatively, the tilt limiting portion may be formed in the movable housing. Furthermore, in this embodiment, the terminal 30 is held by the fixed housing 10 and the movable housing 20, with the tilt limiting portion 12A formed in the fixed housing 10. However, alternatively, the housing holding the terminal and the housing having the tilt limiting portion may be constructed as separate components. Specifically, in such a configuration, the housing may include, in addition to the fixed and movable housings holding the terminal, a separate housing component having the tilt limiting portion formed therein.

[0086] In this embodiment, the housing of the connector 1 is a so-called floating type, separated into a fixed housing 10 and a movable housing 20. However, the present invention is not limited to this, and a type formed by a single housing may also be employed. Furthermore, the terminal arrangement wall of the housing may not be a side wall as shown in this embodiment, but may be a central upright wall located within the peripheral wall, or an upright wall not surrounded by the peripheral wall. Furthermore, the number of terminal arrangement walls may be single or multiple.

[0087] Furthermore, in this embodiment, the tilt limiting portion 12A is formed as part of the fixed housing 10 of the connector 1. However, the tilt limiting portion may also be formed on other components mounted on the housing, such as metal parts. This also applies when the connector 1 is a single housing with a fixed housing and a movable housing that are not separated. When the tilt limiting portion is formed as a metal part, the strength of the tilt limiting portion is improved compared to when the tilt limiting portion is formed from a resin, which is a common housing material, and the tilt of the mating connector can be more effectively limited. This also applies when the connector housing is not separated into a fixed housing and a movable housing.

[0088] In addition, in this embodiment, the plug-in / out direction limiting portion and the tilt limiting portion are provided on the connector I serving as the socket connector, and the plug-in / out direction limiting portion and the tilt limiting portion are provided on the object connector II serving as the plug connector. However, the form of the connector provided with each portion is not limited thereto. For example, the plug-in / out direction limiting portion and the tilt limiting portion may be provided on the plug connector, and the plug-in / out direction limiting portion and the tilt limiting portion may be provided on the socket connector.

[0089] In the present embodiment, the case where the object connector II is tilted in such a manner that the end portion on the X1 side of the object connector II in the terminal arrangement direction X is lifted when the object connector II is pulled out is described. However, in the case where the object connector II is tilted in such a manner that the end portion on the X2 side of the object connector II is lifted, the X2 side becomes one end side and the X1 side becomes the other end side, and the tilting of the object connector II greater than the prescribed angle is restricted due to the same principle as described in the present embodiment.

[0090] In this embodiment, the inclined surface 21B-1 of the end wall 21B of connector I is formed at such an angle of inclination (the angle of inclination relative to the vertical direction Z) that, when the tilted restricted portion 50B-1 of the mating connector II, which is in an inclined position, abuts against the tilted restricted portion 12A of connector I, the end surface 50D-2 of the central wall 50D of the mating connector II abuts (contacts) the inclined surface 21B-1. However, the angle of the inclined surface can also be formed at a larger angle. When the inclined surface is formed at such a large angle, when the tilted restricted portion of the mating connector abuts against the tilted restricted portion of the connector, the end surface of the central wall of the mating connector does not abut (contact) the inclined surface of the end wall of the connector, but rather a gap is formed between the end surface and the inclined surface in the terminal arrangement direction. That is, in this case, the tilt of the mating connector greater than the specified angle is restricted only by the tilted restricted portion of the connector, not by the inclined surface.
