Abstract

In a socket connector and a connector set having a floating structure, a shielding effect against electromagnetic waves is obtained. A connector (1) is formed by fitting a socket connector (10) and a plug connector (100) together. The socket connector (10) includes a fixed-side housing (20), a movable-side housing (40) that is fitted to the plug connector (100), socket contacts (60) that contact the plug connector (100), a shielding member (70), and a grounding sheet (80, 90) having elastic sheet portions (83a-c, 93a-c) that are elastically deformed by pressing a shielding plate (73, 74). In a state in which the movable-side housing (40) is attached to the fixed-side housing (20), a fitting portion (43) moves relative to short-side side walls (21, 22) and long-side side walls (23, 24). In conjunction with this, the elastic sheet portions (83a-c, 93a-c) press the shielding plate (73, 74) by a pressing force corresponding to a horizontal distance from the shielding plate (73, 74).

Description

Technical Field

[0001] This invention relates to a socket connector having a floating structure and a connector assembly. Background Technology

[0002] In the prior art, there are connectors with a floating structure, which are substrate-to-substrate connectors that allow connectors to be positioned and fitted together, and a portion of the connector housing is movable relative to the housing body. In this type of connector, in order to suppress noise caused by electromagnetic waves generated from the connector or by external electromagnetic waves, a specific area of ​​the connector housing is covered with a metal shield.

[0003] As a connector having the aforementioned general floating structure and covering a specific area of ​​the housing with a shield, a general floating connector is known (for example, see Patent Document 1), which includes: a movable side housing having a mating portion formed therefor engaging with a counterpart connector; a fixed side housing supporting the movable side housing relatively movable; a contact being supported across the movable side housing and the fixed side housing, and contacting the counterpart contact of the counterpart connector when engaged with the counterpart connector; and a shielding shell being mounted across the movable side housing and the fixed side housing. This floating connector is configured such that the contact is supported across the movable side housing and the fixed side housing. In the aforementioned state, the shielding shell is elastically deformed in a specific direction orthogonal to the aforementioned fitting direction, so that the aforementioned movable side shell can move relative to the aforementioned fixed side shell in the aforementioned specific direction. The shielding shell includes: a movable side shell portion, which is fixed to the aforementioned movable side shell and covers at least a portion of the outer surface of the aforementioned movable side shell; a fixed side shell portion, which is fixed to the aforementioned fixed side shell and covers at least a portion of the outer surface of the aforementioned fixed side shell; and an elastic shell portion, which connects the aforementioned movable side shell portion and the aforementioned fixed side shell portion. The aforementioned elastic shell portion is configured to follow the relative movement of the aforementioned movable side shell relative to the aforementioned fixed side shell in the aforementioned specific direction and elastically deform in the aforementioned specific direction.

[0004] In the connector disclosed in Patent Document 1, a shielding shell capable of elastic deformation is used as a shield. The shielding shell is fixed to both the movable side shell and the fixed side shell. When the movable side shell moves relative to the fixed side shell, the elastic shell portion connecting the movable side shell portion and the fixed side shell portion becomes elastically deformable.

[0007] [Patent Document 1] Japanese Patent No. 6785184 Summary of the Invention

[0008] [The problem the invention aims to solve]

[0009] However, in the aforementioned connector, because it employs a configuration where "when the movable side housing moves relative to the fixed side housing, the elastic shell portion within the shielding shell elastically deforms in a specific direction," it is necessary to form the elastic shell portion with a narrower width compared to the area surrounding it within the shielding shell. As a result, the area of ​​the shielding shell covering the connector becomes smaller, potentially leading to insufficient suppression of noise caused by electromagnetic waves generated from the connector or by external electromagnetic waves, thus failing to achieve the desired shielding effect.

[0010] Furthermore, in the aforementioned connector, since the shielding shell is fixed to both the movable side shell and the fixed side shell, when the movable side shell moves relative to the fixed side shell, the shielding shell will also move accordingly. Therefore, the shielding shell may not be able to adequately cover the area around the connector, and there is a possibility that it may not be able to adequately suppress noise caused by electromagnetic waves generated from the connector or by external electromagnetic waves, thus failing to achieve the shielding effect.

[0011] This invention was made to solve this problem, and its purpose is to provide a connector that can fully exert the shielding effect on electromagnetic waves in a connector having a floating structure.

[0012] [Methods used to solve problems]

[0013] To achieve the aforementioned objective, the socket connector of the present invention is configured as follows: It comprises a box-shaped fixed-side housing having a pair of first sidewall portions facing each other along its long side and a pair of second sidewall portions facing each other along its short side; and a movable-side housing having a fitting portion, a protruding portion, and a pair of flat, supported portions. The fitting portion is inserted into the opening space formed by the pair of first sidewall portions and the pair of second sidewall portions, and engages with the other connector. The protruding portion extends within the fitting portion and protrudes along its long side. The pair of flat, supported portions... The support portion extends horizontally outward from the short side of the aforementioned mating portion and is supported by the upper surfaces of the aforementioned pair of second sidewall portions; the contact portion has one end held at one of the aforementioned second sidewall portions and the other end held at the aforementioned protruding portion, and contacts the opposing contact of the aforementioned opposing connector; the shielding member includes a first shielding portion, a second shielding portion, and a third shielding portion, the first shielding portion being fixed to the aforementioned fixed side housing and covering the aforementioned pair of first sidewall portions, the second shielding portion being fixed to the aforementioned fixed side housing and covering the aforementioned pair of second sidewall portions. The third shielding portion is connected to the aforementioned first and second shielding portions and covers the aforementioned supported portion; and a pair of grounding plates, each having a pair of horizontal plate portions, a first elastic plate portion, a vertical plate portion, and a second elastic plate portion. The pair of horizontal plate portions are provided at the aforementioned pair of supported portions of the aforementioned movable side housing. The first elastic plate portion is provided at the end of one of the aforementioned horizontal plate portions in the short side direction and elastically deforms by pressing one of the aforementioned second shielding portions. The vertical plate portion covers the inner surface of the aforementioned fitting portion and is formed with an opening, and is positioned relative to the front... The horizontal plate portion is vertically connected to the other end in the short side direction. The second elastic plate portion is provided at the other end in the short side direction of the horizontal plate portion and is elastically deformed in a way that protrudes from the vertical plate portion. When the movable side housing is installed on the fixed side housing, the fitting portion moves relative to the pair of first side wall portions and the pair of second side wall portions in the opening space. Along with this, the first elastic plate portion presses the second shielding portion by a pushing force corresponding to the horizontal distance from the second shielding portion.

[0014] When the movable side housing moves relative to the fixed side housing, and elastic displacement of the shielding plate is required, it is necessary to configure the elastic displacement portion to be more elongated than the surrounding parts in order to facilitate the displacement of the elastic displacement portion. However, in the socket connector of the present invention, when the movable side housing moves relative to the fixed side housing, the contact between the grounding plate and the shielding member is maintained because the grounding plate elastically deforms in a specific direction. Therefore, it is not necessary to provide a movable elastic displacement portion at the shielding member itself. Thus, the situation of "providing a movable elastic displacement portion at the shielding member, causing the elastic displacement portion to shift and failing to adequately cover the area around the socket connector" does not occur, and the shielding effect against electromagnetic waves can be achieved.

[0015] Furthermore, in the socket connector of the present invention, since the shielding member is fixed to the fixed side housing, the shielding member is not movable when the movable side housing is movable and floating. Therefore, the situation where "the shielding member itself is movable, thus preventing the socket connector from being adequately covered by the shielding member" does not occur, and the shielding effect against electromagnetic waves can be achieved.

[0016] In the socket connector configured as described above, it can also be configured such that the aforementioned grounding piece has a plurality of the aforementioned first elastic pieces corresponding to the number of contact pins constituting the aforementioned contacts.

[0017] From the viewpoint of shielding effect, it is ideal to increase the area covered by the shielding member or grounding plate if the number of contact pins constituting the contact increases. The socket connector of the present invention, by employing a configuration where increasing the number of contact pins results in a greater number of first elastic portions in the grounding plate, increases the area covered by the shielding plate or grounding plate. Therefore, it can adequately cover the area around the socket connector, thereby achieving a shielding effect against electromagnetic waves.

[0018] In the aforementioned socket connector, it can also be configured such that: the movable side housing has a movable side retaining groove for retaining one end of the aforementioned contact, and the fixed side housing has a fixed side retaining groove for retaining the other end of the aforementioned contact.

[0019] With this configuration, the socket connector of the present invention, by providing a movable-side retaining groove on the movable-side housing and a fixed-side retaining groove on the fixed-side housing, can stably retain both ends of the contact, thereby stabilizing the electrical connection of the socket connector.

[0020] In the connector assembly of the present invention, it can also be configured as follows: having a socket connector and a plug connector that engages with the aforementioned socket connector, and the aforementioned socket connector and the aforementioned plug engaging with each other, characterized in that: the aforementioned socket connector has: a box-shaped fixed side housing having a pair of first sidewall portions facing each other in the long side direction and a pair of second sidewall portions facing each other in the short side direction; a movable side housing having a fitting portion, a protruding portion and a pair of flat supported portions, the fitting portion being inserted into the opening space formed by the aforementioned pair of first sidewall portions and the aforementioned pair of second sidewall portions, and engaging with the other connector, the protruding portion extending within the aforementioned fitting portion. The pair of flat, supported portions, which are protruding in the long-side direction, extend horizontally outward from the short-side direction of the mating portion and are supported by the upper surfaces of the second sidewall portions of the pair; a contact, wherein the end of one of the contacts is held at one of the second sidewall portions and the end of the other is held at the protruding portion, and contacts the contact of the opposite contact of the opposite connector; a shielding member, comprising a first shielding portion, a second shielding portion, and a third shielding portion, wherein the first shielding portion is fixed to the fixed-side housing and covers the first sidewall portions of the pair, and the second shielding portion is fixed to the fixed-side housing and covers the pair The second sidewall portion, the third shielding portion is connected to the aforementioned first shielding portion and the aforementioned second shielding portion, and covers the aforementioned supported portion; and a pair of grounding plates, each having a pair of horizontal plate portions, a first elastic plate portion, a vertical plate portion and a second elastic plate portion. The pair of horizontal plate portions are provided at the aforementioned pair of supported portions of the aforementioned movable side housing. The first elastic plate portion is provided at one end of the aforementioned horizontal plate portion in the short side direction and is elastically deformed by pressing one of the aforementioned second shielding portions. The vertical plate portion covers the inner surface of the aforementioned fitting portion and is vertically connected to the other end of the aforementioned horizontal plate portion in the short side direction. The second elastic plate portion... The elastic plate is located at the end opposite to the short side of the aforementioned horizontal plate and is elastically deformed by protruding from the aforementioned vertical plate. When the aforementioned movable side housing is installed on the aforementioned fixed side housing, the aforementioned fitting portion moves relative to the aforementioned pair of first side wall portions and the aforementioned pair of second side wall portions within the aforementioned opening space. Accompanyingly, the aforementioned first elastic plate portion presses the aforementioned second shielding portion by a pushing force corresponding to the horizontal distance from the aforementioned second shielding portion. The aforementioned plug connector includes: a plug housing that fits into the aforementioned movable side housing; and a plug contact that is held by the aforementioned plug housing and contacts the aforementioned socket contact.The plug shield is fixed to the aforementioned plug housing and covers a specific area of ​​the aforementioned plug housing. The aforementioned grounding plate is configured to elastically deform in a specific direction and maintain contact with the aforementioned plug shield when the aforementioned movable side housing moves relative to the aforementioned fixed side housing.

[0021] When the movable side housing moves relative to the fixed side housing, and elastic displacement of the shielding member is required, it is necessary to configure the elastic displacement portion to be more elongated than the surrounding parts in a way that facilitates its displacement. However, in the connector assembly of the present invention, when the movable side housing moves relative to the fixed side housing, the grounding piece elastically deforms in a specific direction, maintaining contact with the shielding member and the plug shielding plate. Therefore, it is not necessary to provide a movable elastic displacement portion at the shielding member and the socket shielding plate themselves. Thus, the situation of "providing a movable elastic displacement portion at the shielding member and the plug shielding member, causing the elastic displacement portion to shift and failing to adequately cover the area around the connector assembly" does not occur, and the shielding effect against electromagnetic waves can be achieved.

[0022] Furthermore, in the connector assembly of the present invention, since the shielding member is fixed to the fixed side housing, the shielding plate is not movable when the movable side housing is movable and floating. Therefore, the situation where "the shielding member itself is movable, thus preventing the connector assembly from being adequately covered by the shielding member" does not occur, and the shielding effect against electromagnetic waves can be achieved.

[0071] The following is for reference. Figures 1-12 The connector 1 of this embodiment will now be described. First, the configuration of connector 1 will be described.

[0072] Figure 1 This is a three-dimensional view of connector 1. The directions of the mutually orthogonal 3D coordinate axes x, y, and z, as shown in this figure, are the same in the following figures. The z-axis direction is also referred to as the up-down direction, and the direction parallel to the xy-plane is referred to as the horizontal direction. Connector 1 includes a socket connector 10 and a plug connector 100 that is fitted into and conductive with the socket connector 10. Connector 1 functions, for example, as a substrate-to-substrate connector that electrically connects a pair of parallel circuit boards to each other.

The socket connector 10 includes a fixed-side housing 20, a movable-side housing 40, a contact 60, a shielding member 70, and grounding plates 80 and 90 (see reference). Figure 8 , 9The socket connector 10 is configured such that the contact 60 contacts the contact of the plug connector 100 (described later), and thus it is fitted together with the plug connector 100, which is the other connector, to form connector 1.

[0075] (Fixed side housing)

[0076] Figure 3 This is a perspective view illustrating the fixed-side housing 20, which is part of the housing of the socket connector 10. The mutually orthogonal 3D coordinate axes x-axis, y-axis, and z-axis are shown in the figure. The fixed-side housing 20 is a box-shaped housing and includes short-side sidewalls 21 and 22 facing each other in the x-axis direction, and long-side sidewalls 23 and 24 facing each other in the y-axis direction.

[0077] The fixed-side housing 20 forms the negative z-axis direction of the connector 1, that is, the lower side, and is mounted on the external substrate S (see reference). Figure 14 The fixed side housing 20 is fixed in place and supported in a manner that allows it to move relative to the movable side housing 40, which will be described later. The fixed side housing 20 is, for example, made of a synthetic resin such as liquid crystal polymer (LCP).

[0078] An opening 25 is formed in the space surrounded by the short-side side walls 21, 22 and the long-side side walls 23, 24, which are the side walls of the fixed-side housing 20.

Foot 21g is positioned opposite to substrate S and supports fixed side housing 20. Foot 21h is disposed below shielding engagement portion 21c3 and forms part of the lower end of short side wall 21. Foot 21h is positioned opposite to substrate S and supports fixed side housing 20.

[0084] Short side wall 22 Figure 3 It is positioned opposite the short side wall 21 in the x-axis direction and forms part of the wall surface of the fixed side housing 20.

[0085] The upper surface portion 22a forms the positive z-axis direction of the short side wall 22, that is, the upper side surface. The upper surface portion 22a is covered by the shielding member 70 described later. The side surface portion 22e forms the negative y-axis direction of the short side wall 22, that is, the front side surface of the paper. The side surface portion 22e is covered by the shielding member 70. The side surface portion 22f forms the opposite side of the side surface portion 22e in terms of the y-axis. The side surface portion 22f is covered by the shielding member 70. The lower surface portion 22b, which forms the negative z-axis direction of the short side wall 22, that is, the lower side surface, becomes the surface opposite to the external substrate S.

[0086] The outer surface 22c forms the negative x-axis direction of the short side wall 22, that is, the outer surface. The outer surface 22c is covered by the shielding member 70. At a position (not shown) on the lower part near the center of the outer surface 22c, opposite to the shielding engagement portion 21c1 in the x-axis direction, a shielding engagement portion 22c2 that engages with the shielding member 70 is provided. At both ends of the short side wall 22 in the y-axis direction, at positions opposite to the shielding engagement portions 21c2 and 21c3 in the x-axis direction, shielding engagement portions 22c2 and 22c3 that engage with the shielding member 70 are respectively provided.

[0087] In this embodiment, although each shielding latch 22c2 and 22c3 is set as described above, the position and number of shielding latches are not limited, and other configurations may be adopted.

[0088] The inner surface portion 22d forms the positive direction of the x-axis of the short side wall 22, that is, the inner surface. The inner surface portion 22d, together with the inner surface portion 21d and the inner surfaces of the long side wall 23 and the long side wall 24 described later, delineate the opening portion 25.

[0089] A foot 22g is disposed below the shielding engagement portion 22c2 and forms part of the lower end of the short side wall 22. The foot 22g is positioned opposite to the substrate S and supports the fixed side housing 20. A foot (not shown) is disposed below the shielding engagement portion 22c3 and forms part of the lower end of the short side wall 22. The foot is positioned opposite to the substrate S and supports the fixed side housing 20.

[0090] Long side sidewall 23 Figure 3 It is positioned opposite the long side wall 24 along the y-axis and forms part of the wall of the fixed side housing 20. The long side wall 23 is formed by the two ends 26 and 27 and the central part 28.

[0091] Both ends 26 are connected to the short side wall 22, and both ends 27 are connected to the short side wall 21. Two ends 26 and two ends 27 are respectively provided on both sides of the central portion 28 in the x-axis direction. In this embodiment, the two ends 26 and two ends 27 have the same shape, but they may also have different shapes.

[0092] The upper surface 26a forms the positive direction of the z-axis of both ends 26, that is, the upper side surface. The upper surface 26a serves to support the movable side housing 40, which will be described later, in a way that allows for relative movement. The lower surface 26b forms the negative direction of the z-axis of both ends 26, that is, the lower side surface. The lower surface 26b is the part that is mounted and fixed to the external substrate S. Both ends 26 have feet 26b1 formed in a slightly cuboid shape at the lower surface 26b and fixed to the external substrate S. The feet 26b1 in the lower surface 26b of both ends 26 do not contact the substrate S, and a gap is formed between them and the substrate S.

[0093] The lower part 26b protrudes outward in the negative direction of the y-axis, that is, outward, and has a shielding engagement part 26b2 between itself and the outer surface part 26c, which can insert and engage a part of the shielding member 70 described later in the z-axis direction, that is, in the vertical direction.

[0094] The outer surface 26c forms the negative direction of the y-axis of both ends 26, that is, the outer surface. The outer surface 26c is covered by the shielding member 70 described later. The inner surface 26d, which forms the positive direction of the y-axis of both ends 26, that is, the inner surface, together with the inner surface 27d and 28d described later, forms part of the wall surface that defines the opening 25.

[0095] The upper surface 27a forms the positive z-axis direction of both ends 27, that is, the upper side surface. The upper surface 27a serves to support the movable side housing 40, which will be described later, in a way that allows for relative movement. The lower surface 27b forms the negative z-axis direction of both ends 27, that is, the lower side surface. The lower surface 27b forms the surface opposite to the external substrate S. Both ends 27 have feet 27b1 formed in a slightly cuboid shape at the lower surface 27b that are in contact with the external substrate S. There is a gap between the lower surface 27b of both ends 27 and the substrate S because the portion of the lower surface 27b without feet 27b1 does not have feet 27b1.

[0096] The lower part 27b protrudes outward in the negative direction of the y-axis, that is, outward, and has a shielding engagement part 27b2 between itself and the outer surface part 27c, which can insert and engage a part of the shielding member 70 described later in the z-axis direction, that is, in the vertical direction.

[0097] The outer surface 27c forms the negative direction of the y-axis of both ends 27, that is, the outer surface. The outer surface 27c is covered by the shielding member 70 described later.

[0194] (Plug contacts)

[0195] The plug contact 120 is held in the contact holding groove and contact holding groove 114d of the long side wall 113. When the plug contact 110 is engaged with the socket contact 10 as described later, the plug contact 120 contacts the socket contact 60 held in the contact holding groove 44a of the protruding part 44.

[0196] (Plug shielding)

[0197] Figure 12 (a) is from and Figure 10 (a) A perspective view of the plug shield 130 taken from the same side. Figure 12 (b) is a perspective view taken from the opposite side. The plug shield 130 is equipped with the same features as the plug shield 140 (see reference). Figure 10 The plugs have the same shape and size and are symmetrically arranged at the plug housing 110. The plug shields 130 and 140 are fixed to the plug housing 110 and cover the sides of the plug housing 110. The plug shields are made of, for example, copper alloy or SUS.

[0198] The plug shield 130 includes a flat plate portion 131, a base cover portion 132, mounting plates 133 and 134, and shielding latching plates 135 to 138. The flat plate portion 131 is a flat plate-shaped member provided to cover the long side wall 113. The base cover portion 132 is a cover member provided to cover the base portion 113c that protrudes outward, and is formed by bending.

[0199] The mounting pieces 133 and 134 are paired pieces located at the lower ends of the plug shield 130 in the x-axis direction. They are bent horizontally at the lower end of the flat plate portion 131 to form contact portions that contact the external substrate S. These contact portions constitute part of the conduction path of the connector 1, which is a substrate-to-substrate connector. Mounting piece 133 is located on the positive x-axis side, and mounting piece 134 is located on the negative x-axis side.

[0200] Shielding latches 135, 136, 137, and 138 are tabs provided on the upper part of the plug shield 130, extending from one end to the other along the x-axis, and engage with engaging portions 111a, 112a, 113a, and 113b of the plug housing 110.

[0204] The following is for reference. Figures 13-17 The function of connector 1 in this embodiment will be explained. Figure 13 yes Figure 1 A top view of connector 1 in its current state. Figure 14 It is along in Figure 13 A cross-sectional view of connector 1 in section AA. Figure 13 as well as Figure 14 The connector in the state is to enable Figure 2 The socket connector 10 in the state of Figure 10 (b) The connector 100 in state (b) is engaged.

[0205] Connector 1, in Figure 14 In the state shown, the fixed-side housing 20 and the movable-side housing 40 of the socket connector 10 are aligned in the y-axis direction, that is, in the horizontal direction. Hereinafter, the position of the movable-side housing 40 in this state will be referred to as the reference position.

[0206] The connector 1 in this embodiment is configured such that the movable housing 40 can move relative to the connector 20 of the socket connector 10 in the horizontal direction. With this configuration, even when there is a misalignment between the substrates S or a misalignment in the mating position between the socket connector 10 and the plug connector 100, which is the counterpart connector, the misalignment can be absorbed, and the connector can function as a floating connector.

[0207] The movable side housing 40 at connector 1 restricts horizontal movement by having its outer wall surface 43b and outer wall surface 43c of the fitting portion 43 of the movable side housing 40 contact the inner surface portion 28d of the central portion 28 of the long side side wall 23 and the inner surface portion 32d of the central portion 32 of the long side side wall 24 of the fixed side housing 20.

[0208] exist Figure 14 At the reference position shown, the horizontal distance between the outer wall surface 43b and the inner surface portion 28d is L1, and the horizontal distance between the outer wall surface 43c and the inner surface portion 32d is L2. The outer wall surfaces 43b and 43c do not contact each other with the inner surface portions 28d and 32d, but are provided with specific gaps. At the reference position, L1 = L2.

[0209] At this time, the elastic portions 83a, 83b, and 83c of the grounding plate 80 press the shielding plate 73 towards the left in the figure and make contact with it through pushing force. Similarly, the elastic portions 93a, 93b, and 93c of the grounding plate 90 on the opposite side press the shielding plate 74 towards the right in the figure and make contact with it through pushing force.

[0210] Furthermore, the elastic portions 85a, 85b, 85c, and 85d of the grounding plate 80 press and make contact with the flat portion 131 of the plug shield 130 of the plug connector 100 in the right direction in the figure through pushing force. Similarly, the elastic portions 95a, 95b, 95c, and 95d of the grounding plate 90 on the opposite side press and make contact with the flat portion 141 of the plug shield 140 of the plug connector 100 in the left direction in the figure through pushing force.

[0211] In this way, at the reference position, the contact between the grounding plate 80 and the shielding member 70 and the plug shields 130, 140 is maintained.

[0212] The socket connector 10 is fixed to the external substrate S by soldering or the like. The plug connector 100 is fixed to the external substrate S' by soldering or the like. One end of the contact pin 61 on the socket side has a wire portion 61e that contacts the substrate S. The other end of the contact pin 61 has a contact portion 61a that contacts one end of the plug contact 120 on the plug side. The other end of the plug contact 120 contacts the external substrate S'. In this way, the connector 1 forms a substrate-to-substrate connector, ensuring a conductive path from the substrate S to the substrate S'.

[0213] Next, use Figure 15 The following describes a situation where there is a positional offset between the socket connector 10 and the plug connector 100 from the aforementioned reference position at connector 1. Figure 15 (a), for in Figure 13 The diagram illustrates a state where the connector 1 is in its current position and the movable housing 40 has moved to the left from its reference position. At this time, the horizontal distance between the outer wall surface 43b and the inner surface portion 28d is approximately zero. On the other hand, the horizontal distance between the outer wall surface 43c and the inner surface portion 32d is L3, which, compared to L1 at the reference position, is L3 > L1, meaning L3 is larger than L1.

[0214] At this time, the elastic portions 83a, 83b, and 83c of the grounding plate 80 press the shielding plate 73 towards the left in the figure and make contact with it through pushing force. Similarly, the elastic portions 93a, 93b, and 93c of the grounding plate 90 on the opposite side press the shielding plate 74 towards the right in the figure and make contact with it through pushing force. Figure 15 In state (a), since the movable side housing 40 has moved to the left compared to the reference state, the horizontal displacement of the elastic plates 83a, 83b, and 83c is greater than that in the reference state. On the other hand, the horizontal displacement of the elastic plates 93a, 93b, and 93c on the opposite side is smaller than that in the reference state.

[0215] Furthermore, regarding the horizontal displacement of the elastic portions 85a, 85b, 85c, 85d of the grounding plate 80 and the elastic portions 95a, 95b, 95c, 95d of the grounding plate 90, since the relative positions between the grounding plates 80 and 90 and the plug shields 130 and 140 will not change even if the movable side housing 40 moves, there will be no change.

[0216] Figure 15 (b), for in Figure 13The diagram shows the connector 1 in its current state, with the movable housing 40 moved to the right from its reference position. At this time, the horizontal distance between the outer wall surface 43c and the inner surface portion 32d is approximately zero. On the other hand, the horizontal distance between the outer wall surface 43b and the inner surface portion 28d is L3, which, compared to L2 at the reference position, is L3 > L2, meaning L3 is larger than L2.

[0217] At this time, the elastic portions 83a, 83b, and 83c of the grounding plate 80 press the shielding plate 73 towards the left in the figure and make contact with it through pushing force. Similarly, the elastic portions 93a, 93b, and 93c of the grounding plate 90 on the opposite side press the shielding plate 74 towards the right in the figure and make contact with it through pushing force. Figure 15 In state (b), since the movable side housing 40 has moved to the right compared to the reference state, the horizontal displacement of the elastic plates 83a, 83b, and 83c is smaller than that in the reference state. On the other hand, the horizontal displacement of the elastic plates 93a, 93b, and 93c on the opposite side is larger than that in the reference state.

[0218] In this way, Figure 15 In connectors 1 in states (a) and (b), the contact between the grounding plates 80 and 90 and the shielding member 70 and the plug shields 130 and 140 is maintained, similar to the situation in the reference position. Furthermore, although the figures are omitted, in addition to the reference position... Figure 15 In states other than (a) and (b) (for example, in the case of...) Figure 15 (a) where L3 is set to half the distance), similarly, the contact between the grounding plates 80, 90 and the shielding member 70 and the plug shields 130, 140 is maintained.

[0219] Furthermore, with the movable side housing 40 installed on the fixed side housing 20, the fitting portion 43 moves relative to the short side walls 21 and 22 and the long side walls 23 and 24 within the opening 25. Simultaneously, the elastic plates 83a, 83b, and 83c press against the shielding plates 73 and 74 with a pushing force corresponding to a horizontal distance from the shielding plates 73 and 74. Additionally, the grounding plates 80 and 90, during relative movement with the movable side housing 40 relative to the fixed side housing 20, elastically deform and maintain contact with the plug shields 130 and 140.

[0220] Figure 16 as well as Figure 17This is a perspective view used to illustrate the contact state between the grounding plates 80 and 90 and the shielding member 70 and the plug shields 130 and 140 at the aforementioned reference positions.

[0221] Figure 16 For in Figure 13 A perspective view of the AA cross-section of the socket connector and plug connector in their mating state is shown. In this mating state, the elastic piece 83a is in contact with the shielding plate 73, and the grounding piece 80 is in contact with the shielding member 70.

[0222] Figure 17 For in Figure 13 A perspective view of the BB cross-section of the socket connector and plug connector in their mating state is shown. In this state, the elastic piece 85a is in contact with the flat plate 131, and it can be seen that the grounding piece 80 is in contact with the plug shield 130.

[0223] In this way, the connector 1 of this embodiment can maintain contact with the shielding member 70 and the plug shields 130 and 140 by elastically deforming a part of the grounding piece 80. Even without a deformable part at the shielding member 70, it can fully cover the area around the connector, thereby improving the shielding effect.

[0224] As described above, the connector 1 of this embodiment includes a socket connector 10 and a plug connector 100 that engages with the socket connector 10, and the socket connector 10 and the plug connector 100 are mutually engaged. The socket connector 10 includes: a box-shaped fixed-side housing 20, having short-side side walls 21 and 22 facing each other in the long-side direction, and long-side side walls 23 and 24 facing each other in the short-side direction; and a movable-side housing 40, having a fitting portion 43, a protruding portion 44, and a flat-shaped supported portion 41 and 42. The fitting portion 43 is inserted into the opening 25 formed by the short-side side walls 21 and 22 and the long-side side walls 23 and 24, and engages with the plug connector 100. The connector 100 is engaged, and the protruding part 44 is protruding in the long side direction extending within the engagement part 43. A pair of flat, supported parts 41 and 42 extend horizontally outwards from the short side direction of the engagement part 43 and are supported by the upper surfaces of the long side sidewalls 23 and 24. A socket contact 60 is provided, with one end held at one of the long side sidewalls 23 and 24 and the other end held at the protruding part 44, and in contact with the plug contact 120 of the plug connector 100. A shielding member 70 includes shielding plates 71 and 72, shielding plates 73 and 74, and shielding plate 75. The shielding plates 71 and 72... The shielding plates 73 and 74 are fixed to the fixed side housing 20 and cover the short side side walls 21 and 22. The shielding plates 73 and 74 are fixed to the fixed side housing 20 and cover the long side side walls 23 and 24. The shielding plate 75 is connected to the shielding plates 71 and 72 and the shielding plates 73 and 74 and covers the supported parts 41 and 42. The grounding plates 80 and 90 have horizontal plate parts 81 and 91, elastic plate parts 83a-83c and 93a-93c, vertical plate parts 82 and 92, and elastic plate parts 85a-85d and 95a-95d. The horizontal plate parts 81 and 91 are provided at the supported parts 41 and 42 of the movable side housing 40. The elastic plate parts 83a-85d and 95a-95d are provided at the supported parts 41 and 42 of the movable side housing 40. 3c, 93a-93c are provided at one end of the short side of the horizontal plate portions 81, 91 and are elastically deformed by pressing the shielding plates 73, 74. The vertical plate portions 82, 92 cover the inner surface of the fitting portion 43 and are formed with openings 84a-84d, 94a-94d, and are vertically connected to the other end of the horizontal plate portions 81, 91 in the short side direction. The elastic sheet portions 85a-85d, 95a-95d are provided at the other end of the horizontal plate portions 81, 91 in the short side direction and are elastically deformed by protruding from the openings 84a-84d, 94a-94d.

[0225] Furthermore, in the state where the movable side housing 40 is installed on the fixed side housing 20, the fitting part 43 moves relative to the short side side walls 21, 22 and the long side side walls 23, 24 within the opening 25. Accompanying this, the elastic sheet parts 83a-83c, 93a-93c press the shielding plates 73, 74 with a pushing force corresponding to the horizontal distance from the shielding plates 73, 74.

[0226] Furthermore, the plug connector 100 includes a plug housing 110 that engages with the movable side housing 40, a plug contact 120 that is held at the plug housing 110 and contacts the socket contact 60, and plug shields 130 and 140 that are fixed at the plug housing 110 and cover a specific area of ​​the plug housing 110. When the movable side housing 40 moves relative to the fixed side housing 20, the grounding plates 80 and 90 become elastically deformed in a specific direction and maintain contact with the plug shields 130 and 140.

[0227] When the movable housing 40 moves relative to the fixed housing 20, and the shielding member 70 needs to be elastically displaced, it is necessary to configure the elastic displacement portion to be more elongated than the surrounding parts in a way that facilitates the displacement of the elastic displacement portion. However, in the connector 1 of this embodiment, when the movable housing 40 moves relative to the fixed housing 20, the grounding plates 80 and 90 elastically deform in the horizontal direction, and the contact between them and the shielding member 70 is maintained. Therefore, it is not necessary to provide a movable elastic displacement portion at the shielding member 70 itself. Thus, the situation of "providing a movable elastic displacement portion at the shielding member 70, causing the elastic displacement portion to shift and failing to adequately cover the area around the connector" does not occur, and the shielding effect against electromagnetic waves can be achieved.

[0228] Furthermore, in this embodiment of the connector 1, since the shielding member 70 is fixed to the fixed-side housing 20, the shielding member 70 is not movable when the movable-side housing 40 is movable and floating. Therefore, the situation where "the shielding member 70 itself is movable, thus preventing the connector's surroundings from being adequately covered by the shielding member 70" does not occur, and the shielding effect against electromagnetic waves can be achieved.

[0229] Furthermore, the connector 1 of this embodiment is configured such that its grounding plates 80 and 90 have a plurality of elastic plates 83a-83c and 93a-93c corresponding to the number of contact pins 61 constituting the aforementioned socket contact 60.

[0230] From the viewpoint of shielding effect, it is ideal to increase the number of contact pins constituting the contacts, thereby increasing the area covered by the shielding members or grounding plates. In the connector 1 of this embodiment, because it employs a configuration that increases the number of elastic portions 83a-83c, 93a-93c of the grounding plate 80 in relation to the number of contact pins 61 constituting the socket contacts 60, the area covered by the shielding members 70 or the grounding plates 80, 90 can be increased. Therefore, the area around the connector 1 can be sufficiently covered, thereby achieving a shielding effect against electromagnetic waves.

[0231] Furthermore, the connector 1 in this embodiment is configured as follows: a movable side housing 40 having a contact retaining groove 44a for retaining one end of the socket contact 60, and a fixed side housing 20 having a contact retaining groove for retaining the other end of the socket contact 60.

[0232] With this configuration, the connector 1 of this embodiment has a contact retaining groove 44a provided at the movable side housing 40 and a contact retaining groove provided at the fixed side housing 20. Therefore, both ends of the socket contact 60 can be stably retained, thereby stabilizing the electrical connection of the connector 1.

[0233] Furthermore, the technical scope of the connector of the present invention is not limited to the above-described embodiments, but also includes various modifications to the constituent elements described in the claims.

[0234] As described above, the socket connector and connector assembly of the present invention have the effect of "fully exerting the shielding effect on electromagnetic waves in connectors with a floating structure", and are useful for various connectors.
