Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to transmit a large number of signals, a plurality of connectors as described above may be prepared and arranged in proximity on a substrate.

[0005] A first object of the present disclosure is to suppress displacement of the relative position between a terminal (first terminal) held by a first movable housing and a terminal (second terminal) held by a second movable housing when the first movable housing and the second movable housing are provided. A second object of the present disclosure is to suppress breakage of a restraint space forming portion in a connector in which a restraint space forming portion having a pair of side walls and a top wall is formed in a fixed housing. A third object of the present disclosure is to miniaturize a connector including a first movable housing and a second movable housing in the arrangement direction (the direction in which the first movable housing and the second movable housing are arranged).

Means for Solving the Problems

[0006] ≪First Aspect≫ A connector according to aspect 1-1 includes a fixed housing whose position relative to an attachment object is fixed, a first movable housing movable relative to the fixed housing, the first movable housing having a first fitting portion that can be fitted with a first connection object, a second movable housing movable relative to the fixed housing, the second movable housing having a second fitting portion that can be fitted with a second connection object, a first fixed-side held portion held by the fixed housing, a first movable-side held portion held by the first movable housing, and a connector positioned between the first fixed-side held portion and the first movable-side held portion. a first terminal having a first intermediate portion, a second terminal having a second fixed side held portion held by the fixed housing, a second movable side held portion held by the second movable housing, and a second intermediate portion located between the second fixed side held portion and the second movable side held portion, wherein the fixed housing has a first terminal holding portion that holds the first fixed side held portion of the first terminal, and a second terminal holding portion that holds the second fixed side held portion of the second terminal, and at least the first terminal holding portion and the second terminal holding portion of the fixed housing are integrally molded from resin.

[0007] In the above aspect, the connector comprises a fixed housing whose position relative to an attachment object (e.g., a substrate), a first movable housing movable relative to the fixed housing, the first movable housing having a first mating portion that can mate with a first connection object, and a second movable housing movable relative to the fixed housing, the second movable housing having a second mating portion that can mate with a second connection object. The connector also includes a first terminal and a second terminal. The first terminal has a first fixed-side held portion held by the fixed housing, a first movable-side held portion held by the first movable housing, and a first intermediate portion located between the first fixed-side held portion and the first movable-side held portion. The second terminal has a second fixed-side held portion held by the fixed housing, a second movable-side held portion held by the second movable housing, and a second intermediate portion located between the second fixed-side held portion and the second movable-side held portion. The fixed housing has a first terminal holding portion that holds the first fixed-side held portion of the first terminal and a second terminal holding portion that holds the second fixed-side held portion of the second terminal.

[0008] Here, if the portion of the fixed housing that holds the first terminal (the first terminal holding portion) and the portion of the fixed housing that holds the second terminal (the second terminal holding portion) are separate bodies, the relative positions of the first fixed-side held portion of the first terminal and the second fixed-side held portion of the second terminal may deviate from the predetermined positions. On the other hand, in the above aspect, since the portion of the fixed housing that holds the first terminal (the first terminal holding portion) and the portion of the fixed housing that holds the second terminal (the second terminal holding portion) are integrally formed of resin, the relative positions of the first fixed-side held portion of the first terminal and the second fixed-side held portion of the second terminal are suppressed from deviating from the predetermined positions.

[0009] In the connector according to the 1-2 aspect, in the 1-1 aspect, the fixed housing has an intermediate portion that connects the first terminal holding portion and the second terminal holding portion, and a gate trace is formed in the intermediate portion.

[0010] In the above aspect, a gate trace (a trace formed at a position corresponding to the gate through which the molten resin flows into the molding die) is formed in the intermediate portion that connects the first terminal holding portion and the second terminal holding portion. Therefore, when molding the fixed housing, the molten resin can be made to flow in from the portion located between the first terminal holding portion and the second terminal holding portion. As a result, the molten resin can flow efficiently within the molding die, preventing the strength of the fixed housing from decreasing or the shape of the fixed housing from becoming distorted. Note that it is preferable from the viewpoint of making the flow of the molten resin from the intermediate portion smooth that a press-fitting portion into which a fixing fitting is press-fitted is not formed in the intermediate portion of the fixed housing.

[0011] In the connectors according to the first to third aspects, in the first to first or first to second aspects, the fixed housing has an accommodation space that penetrates the fixed housing in the vertical direction and houses the first movable housing and the second movable housing, and an intermediate connecting portion that divides the accommodation space into a first accommodation space for housing the first movable housing and a second accommodation space for housing the second movable housing.

[0012] In the above aspect, the fixed housing has an accommodation space that penetrates the fixed housing in the vertical direction and houses the first movable housing and the second movable housing. The accommodation space is divided by an intermediate connecting portion of the fixed housing into a first accommodation space for housing the first movable housing and a second accommodation space for housing the second movable housing. Therefore, it is possible to suppress the resin constituting the fixed housing from shrinking during molding of the fixed housing and the fixed housing from deforming along with the shrinkage.

[0013] In the connectors according to the first to fourth aspects, in the first to third aspects, the intermediate connecting portion restricts upward movement of the first movable housing by contacting the first movable housing and restricts upward movement of the second movable housing by contacting the second movable housing.

[0014] In the above aspect, the intermediate connecting portion restricts upward movement of the first movable housing and restricts upward movement of the second movable housing by contacting the second movable housing. Therefore, the intermediate connecting portion can function effectively.

[0015] The connector according to the first to fifth aspects, in any of the first to fourth aspects, the fixed housing has a first upper limiting portion and a second upper limiting portion, the first movable housing has a first upper abutting portion that abuts against the first upper limiting portion to limit the upward movement of the first movable housing, the second movable housing has a second upper abutting portion that abuts against the second upper limiting portion to limit the upward movement of the second movable housing, the first movable housing and the second movable housing are arranged in a predetermined arrangement direction, and both the first upper abutting portion and the second upper abutting portion protrude in the arrangement direction.

[0016] In the above aspect, the upward movement of the first movable housing is restricted by the first upper abutting portion of the first movable housing abutting against the first upper limiting portion of the fixed housing, and the upward movement of the second movable housing is restricted by the second upper abutting portion of the second movable housing abutting against the second upper limiting portion of the fixed housing. Here, the first upper abutting portion and the second upper abutting portion protrude in the arrangement direction, which is the direction in which the first movable housing and the second movable housing are arranged. Therefore, in the direction perpendicular to the arrangement direction among the directions perpendicular to the vertical direction, it is easy to make the connector small.

[0017] A connector according to aspect 1-6 is a connector in any of aspects 1-1 to 1-5, wherein the fixed housing has an accommodating space that penetrates the fixed housing in the vertical direction and accommodates the first movable housing and the second movable housing, and an intermediate connecting portion that divides the accommodating space into a first accommodating space that accommodates the first movable housing and a second accommodating space that accommodates the second movable housing, the fixed housing has a first upper limiting portion and a second upper limiting portion, the first movable housing has a first upper abutting portion that abuts against the first upper limiting portion to limit the upward movement of the first movable housing, the second movable housing has a second upper abutting portion that abuts against the second upper limiting portion to limit the upward movement of the second movable housing, the first movable housing and the second movable housing are arranged in a predetermined arrangement direction, the first upper abutting portion and the second upper abutting portion both protrude in the arrangement direction, and the intermediate connecting portion functions as the first upper limiting portion and the second upper limiting portion.

[0018] <Second Aspect> The connector of aspect 2-1 is a connector comprising a fixed housing whose position relative to an attachment object is fixed, and a movable housing that is movable relative to the fixed housing, wherein the movable housing has a protruding portion that protrudes in a protruding direction that is perpendicular to the up-down direction, the fixed housing has a constraint space forming portion that forms a constraint space in which the protruding portion is constrained, the constraint space forming portion has a pair of side walls located on the sides of the protruding portion and a top wall located above the protruding portion, the top wall restricts the upward movement of the movable housing when the protruding portion abuts against the top wall, and the constraint space forming portion has a reinforcing wall located on the protruding direction side of the protruding portion, the reinforcing wall connecting the pair of side walls.

[0019] In the above aspect, the connector includes a fixed housing whose position with respect to the object to be attached is fixed, and a movable housing that is movable with respect to the fixed housing. The movable housing has a protruding portion that protrudes in a protruding direction, which is a direction perpendicular to the vertical direction. The fixed housing has a constraint space forming portion that forms a constraint space, which is a space where the protruding portion is constrained. The constraint space forming portion has a pair of side walls located on the side of the protruding portion and a top wall located above the protruding portion. The top wall restricts the upward movement of the movable housing when the protruding portion abuts against it.

[0020] Here, the constraint space forming portion is a reinforcing wall located on the protruding direction side with respect to the protruding portion, and has a reinforcing wall that connects the pair of side walls. Therefore, the reinforcing wall reinforces the vicinity of the top wall in the constraint space forming portion, and suppresses damage to the constraint space forming portion.

[0021] In the embodiment described later, the lower surface of the reinforcing wall is in the same plane as the lower surfaces of the pair of side walls, but the reinforcing wall in the above aspect is not limited to this. From the viewpoint of strength, it is preferable that the lower surface of the reinforcing wall is in the same plane as the lower surfaces of the pair of side walls, but the lower surface of the reinforcing wall may be formed above the lower surfaces of the pair of side walls. Also, in the embodiment described later, the upper end of the reinforcing wall is connected to the top wall, but the above aspect is not limited to this. For example, the reinforcing wall and the top wall may not be connected, and an opening may be formed between them. Also, in the embodiment described later, the reinforcing wall is made of resin and is integrally molded with the pair of side walls and the top wall, but the above aspect is not limited to this. For example, the reinforcing wall may be formed of metal. By arranging a metal reinforcing wall on the protruding direction side with respect to the protruding portion, the vicinity of the top wall in the constraint space forming portion can be reinforced without increasing the vertical dimension of the constraint space forming portion. Also, in the embodiment described later, the protruding portion of the movable housing can abut against the pair of side walls of the constraint space forming portion, but the above aspect is not limited to this.

[0022] In the second aspect, in the second aspect, even when the movable housing moves parallel to the protruding direction to the limit, the protruding portion does not contact the reinforcing wall.

[0023] In the above aspect, even when the movable housing moves parallel to the protruding direction to the limit, the protruding portion does not contact the reinforcing wall. Therefore, the strength required for the reinforcing wall itself can be low. Thus, the reinforcing wall can be made thinner and the fixed housing can be miniaturized.

[0024] The connector according to the second aspect is the connector according to the second aspect or the second aspect, wherein the protruding portion has a protruding end face facing the protruding direction side, and a gate trace is formed on the protruding end face.

[0025] In the above aspect, a gate trace is formed on the protruding end face of the protruding portion. In such a movable housing, when trying to secure the size of the gate for injecting the molten resin, there is a limit to the miniaturization of the protruding portion. As a result, a certain size is required for the restraining space in which the protruding portion is restrained. In order to lower the height of the restraining space forming portion of the fixed housing while accommodating the protruding portion with a miniaturization limit, it is conceivable to make the top wall thinner. However, if the top wall is thinned, there is a risk that the restraining space forming portion will be damaged near the thinned top wall when the movable housing abuts strongly against the fixed housing. Therefore, by providing a reinforcing wall, damage to the restraining space forming portion is suppressed. Therefore, the above aspect is effective when forming the restraining space forming portion low in a connector in which a gate trace is formed on the protruding end face of the protruding portion.

[0026] <<Third Aspect>> A connector according to aspect 3-1 is a connector comprising: a fixed housing whose position relative to an attachment object is fixed; a first movable housing movable relative to the fixed housing, the first movable housing having a first fitting portion that can be fitted with a first connection object; a second movable housing movable relative to the fixed housing, the second movable housing having a second fitting portion that can be fitted with a second connection object; a first terminal having a first fixed-side held portion held by the fixed housing, a first movable-side held portion held by the first movable housing, and a first intermediate portion located between the first fixed-side held portion and the first movable-side held portion; and a second terminal having a second fixed-side held portion held by the fixed housing, a second movable-side held portion held by the second movable housing, and a second intermediate portion located between the second fixed-side held portion and the second movable-side held portion, The second movable housing is arranged in a predetermined arrangement direction (e.g., a front-to-rear direction) that is a direction perpendicular to the vertical direction, the first movable housing has a first side protrusion that protrudes in a direction perpendicular to the vertical direction toward the second movable housing (e.g., a rearward direction), the second movable housing has a second side protrusion that protrudes in a direction perpendicular to the vertical direction toward the first movable housing (e.g., a forward direction), the fixed housing has a constraint space forming portion that forms a constraint space that is a space in which both the first side protrusion and the second side protrusion are constrained, the constraint space forming portion has a top wall located above the first side protrusion and the second side protrusion, and the top wall limits the upward movement of the first movable housing and the second movable housing by the abutment of the first side protrusion and the second side protrusion, and the constraint space has a common constraint space in which both the first side protrusion and the second side protrusion can be positioned.

[0027] In the above aspect, the connector comprises a fixed housing, a first movable housing having a first mating portion that can mate with a first connection object, a second movable housing having a second mating portion that can mate with a second connection object, a first terminal, and a second terminal. The first movable housing and the second movable housing are arranged in a predetermined arrangement direction (for example, the front-rear direction), which is a direction perpendicular to the vertical direction. The first movable housing has a first side protruding portion that protrudes in a direction perpendicular to the vertical direction and toward the second movable housing side (for example, the rear direction), and the second movable housing has a second side protruding portion that protrudes in a direction perpendicular to the vertical direction and toward the first movable housing side (for example, the front direction). Further, the fixed housing has a constraint space forming portion that forms a constraint space, which is a space where both the first side protruding portion and the second side protruding portion are constrained. The constraint space forming portion has a top wall located above the first side protruding portion and the second side protruding portion. When the first side protruding portion and the second side protruding portion come into contact, the top wall restricts the upward movement of the first movable housing and the second movable housing.

[0028] Here, the constraint space has a shared constraint space where both the first side protruding portion and the second side protruding portion can be located. Therefore, for example, when the first movable housing moves in a direction away from the second movable housing, the second protruding portion of the second movable housing can move into the space where the first side protruding portion was located before the movement. Also, for example, when the second movable housing moves in a direction away from the second movable housing, the first side protruding portion of the first movable housing can move into the space where the second side protruding portion was located before the movement. That is, at least a part of the constraint space is shared by the first side protruding portion and the second side protruding portion. For this reason, it is easy to miniaturize the connector in the arrangement direction.

[0029] Note that the first connection object and the second connection object may be configured not to displace relative to each other. For example, a mating connector as a connection object of the connector according to the above aspect may include the first connection object and the second connection object, and the mating connector may be configured such that the first connection object and the second connection object do not displace relative to each other. In this case, when the mating connector moves relative to the connector, the first movable housing and the second movable housing will move integrally.

[0030] In the embodiment described later, the entire fixed housing is integrally formed of resin. As a result, the portion of the fixed housing that holds the first terminal (first terminal holding portion) and the portion of the fixed housing that holds the second terminal (second terminal holding portion) are integrally formed of resin. However, the above aspect is not limited to this. For example, the first terminal holding portion and the second terminal holding portion may be formed separately, and the intermediate portion of the fixed housing in the embodiment described later may be composed of a metal member. In this case, a part of the metal member functions as a top wall.

[0031] In the connector according to the third aspect 2, in the third aspect 1, the distance in the arrangement direction (for example, the front-rear direction) between the first-side protruding portion and the second-side protruding portion in the normal state is 1 / 5 or less of the distance that the first movable housing can move in the direction approaching the second movable housing (for example, the rear direction) from the normal state, and 1 / 5 or less of the distance that the second movable housing can move in the direction approaching the first movable housing (for example, the front direction) from the normal state.

[0032] In the above aspect, in the normal state, the first-side protruding portion and the second-side protruding portion are close to each other in the arrangement direction (for example, the front-rear direction). Specifically, the distance in the arrangement direction (for example, the front-rear direction) between the first-side protruding portion and the second-side protruding portion in the normal state is 1 / 5 or less of the distance that the first movable housing can move in the direction approaching the second movable housing (for example, the rear direction) from the normal state, and 1 / 5 or less of the distance that the second movable housing can move in the direction approaching the first movable housing (for example, the front direction) from the normal state. Therefore, it is even easier to miniaturize the connector 1 in the arrangement direction.

Embodiments for Carrying Out the Invention

[0034] In the following description, the arrows X, Y, Z shown in each figure are directional concepts based on the connector and its components. The +X direction is the front direction of the connector, the +Y direction is one side of the width direction of the connector, and the +Z direction is the upward direction of the connector. Simply put, when referring to the front-rear direction, width direction, and up-down direction, it means the front-rear direction of the connector, the width direction of the connector, and the up-down direction of the connector.

[0035] <Schematic> The connector 1 is configured to be connectable to a mating connector with the up-down direction as the connection direction. A connector pair is formed by the connector 1 and a mating connector (not shown). The connector 1 is mounted on a substrate (not shown), and the mating connector is mounted on a mating substrate (not shown). In the state where the connector 1 and the mating connector are connected, the substrate and the mating substrate are arranged parallel to each other with the connector pair in between.

[0036] FIG. 1 is a perspective view of the connector 1, and FIG. 2 is an exploded perspective view of the connector 1.

[0037] The connector 1 includes a fixed housing 2, two movable housings 3, a plurality of terminals 4, and a plurality (four in this embodiment) of fixing brackets 5.

[0038] The fixed housing 2 and the movable housing 3 are formed of an insulator such as synthetic resin. The fixed housing 2 holds a part of the terminal 4 (the fixed-side held portion 4B, see FIG. 8). The fixed housing 2 is fixed to the substrate via the terminal 4 and becomes immovable with respect to the substrate. The movable housing 3 holds the other part of the terminal 4 (the movable-side held portion 4D). The movable housing 3 is movable with respect to the substrate and the fixed housing 2. Each of the plurality of terminals 4 has an intermediate elastic portion 4C between the fixed-side held portion 4B and the movable-side held portion 4D. By the elastic deformation of the intermediate elastic portion 4C, the movement of the movable housing 3 with respect to the fixed housing 2 is allowed.

[0039] Each of the plurality of fixing brackets 5 has a press-fitting portion 5A press-fitted into the fixed housing 2 and a substrate fixing portion 5B fixed to the substrate. The fixing bracket 5 is press-fitted into the fixed housing 2 from above. The fixing of the fixed housing 2 to the substrate is reinforced by the fixing bracket 5.

[0040] <Detailed Structure of Connector 1> The detailed structure of the connector 1 will be described.

[0041] ≪Terminal 4≫ The terminal 4 will be described with reference to FIG. 8 and the like.

[0042] The terminal 4 is manufactured by performing punching and bending processes on a sheet material.

[0043] The plurality of terminals 4 are composed of a plurality of terminals 4 arranged in the front-rear direction (pitch direction) on one side in the width direction (inter-column direction) and a plurality of terminals 4 arranged in the front-rear direction (pitch direction) on the other side in the width direction (inter-column direction). The terminals 4 on one side in the width direction and the terminals 4 on the other side in the width direction are arranged so that the contact portions 4F thereof face each other.

[0044] As shown in FIG. 2, the plurality of terminals 4 are composed of a plurality of first terminals 41 held by the first movable housing 31 and a plurality of second terminals 42 held by the second movable housing 32. The first terminal 41 and the second terminal 42 have the same shape.

[0045] (Configuration of Each Terminal) As shown in FIG. 8, terminal 4 integrally has a substrate fixing portion 4A, a fixed-side held portion 4B, an intermediate elastic portion 4C, a movable-side held portion 4D, a tip elastic portion 4E, and a contact portion 4F from one end to the other end.

[0046] The substrate fixing portion 4A is fixed to the substrate. The substrate fixing portion 4A extends inward in the width direction from one end side to the other end side.

[0047] The fixed-side held portion 4B is held by the fixed housing 2. The fixed-side held portion 4B extends upward and has press-fit protrusions on both sides in the front-rear direction which is the plate width direction. The fixed-side held portion 4B is press-fitted into the fixed housing 2 from below.

[0048] The intermediate elastic portion 4C is configured to be elastically deformable so that the movable-side held portion 4D can be displaced with respect to the fixed-side held portion 4B. The intermediate elastic portion 4C has a first curved portion 4C1, a straight portion 4C2, and a second curved portion 4C3. The first curved portion 4C1 is formed by bending the portion on the other end side of the fixed-side held portion 4B in the plate thickness direction. The straight portion 4C2 extends linearly in a direction inclined inward in the width direction downward. The second curved portion 4C3 is formed by bending the portion on the other end side of the straight portion 4C2 in the plate thickness direction. The second curved portion 4C3 connects the straight portion 4C2 and the movable-side held portion 4D.

[0049] The movable-side held portion 4D is held by the movable housing 3. The movable-side held portion 4D extends upward and has press-fit protrusions on both sides in the front-rear direction which is the plate width direction. The movable-side held portion 4D is press-fitted into the movable housing 3 from below.

[0050] The tip elastic part 4E elastically supports the contact part 4F so that the contact part 4F can be displaced relative to the movable housing 3. The tip elastic part 4E has a first extension part 4E1 on one end side and a second extension part 4E2 on the other end side. Both the first extension part 4E1 and the second extension part 4E2 extend in a direction inclined inward in the width direction upward, but the first extension part 4E1 has a larger inclination angle with respect to the upward direction than the second extension part 4E2.

[0051] The contact part 4F contacts the mating terminal of the mating connector as the "object to be connected". The contact part 4F curves so as to be convex toward the inside in the width direction. A curved part 4F1 is formed between the contact part 4F and the tip elastic part 4E so as to project the contact part 4F inward in the width direction.

[0052] ≪Fixed housing 2≫ The fixed housing 2 will be described with reference to FIGS. 9 to 12 and the like.

[0053] (Terminal holding part 2A) The fixed housing 2 has a terminal holding part 2A. The terminal holding part 2A holds a part (fixed-side held part 4B) of the terminal 4. The terminal holding part 2A has side walls 2A1. A plurality of press-fitting grooves extending in the vertical direction are formed on the inner surface in the width direction of the side walls 2A1. The fixed-side held parts 4B of the plurality of terminals 4 are press-fitted into these plurality of press-fitting grooves from below.

[0054] A plurality of terminal holding parts 2A are formed in the fixed housing 2. The plurality of terminal holding parts 2A are composed of a pair of first terminal holding parts 21A and a pair of second terminal holding parts 22A. The first terminal holding part 21A holds a plurality of first terminals 41, and the second terminal holding part 22A holds a plurality of second terminals 42. A first arrangement space 21S in which the first movable housing 31 is arranged is formed between the pair of first terminal holding parts 21A, and a second arrangement space 22S in which the second movable housing 32 is arranged is formed between the pair of second terminal holding parts 22A.

[0055] The terminal holding portion 2A has an upper wall 2A2 extending inward in the width direction from the upper end of the side wall 2A1. 7, the side wall 2A1 protects the middle elastic portion 4C of the terminal 4 from the outside in the width direction, and the top wall 2A2 protects the middle elastic portion 4C of the terminal 4 from above. The side wall 2A1 and the top wall 2A2 function as "protective walls" that protect the middle elastic portion 4C of the terminal 4.

[0056] The terminal holding portion 2A has a reinforcing portion 2A3 that reinforces the upper wall 2A2 (FIG. 10). The reinforcing portion 2A3 connects the top wall 2A2 and the side wall 2A1 at both ends in the extension direction of the terminal holding portion 2 A. The reinforcing portion 2A3 is formed inside the upper end of the side wall 2A1 in the width direction and below the top wall 2A2.

[0057] (middle part 2B) The fixed housing 2 has an intermediate portion 2B formed between the first terminal holding portion 21A and the second terminal holding portion 22A. The intermediate portion 2B has a side wall 2B1 on one side formed between the first terminal holding portion 21A on one side and the second terminal holding portion 22A on one side, a side wall 2B1 on the other side formed between the first terminal holding portion 21A on the other side and the second terminal holding portion 22A on the other side, and a top wall 2B2 ("intermediate connecting portion") connecting the side walls 2B1 on one side and the other side.

[0058] (front end 21C) The stationary housing 2 has a front end 21C. The front end portion 21C is formed forward of the pair of first terminal holding portions 21A, and connects the front end of the first terminal holding portion 21A on one side to the front end of the first terminal holding portion 21A on the other side.

[0059] (Rear end 22C) The stationary housing 2 has a rear end 22C. The rear end portion 22C is formed rearward of the pair of second terminal holding portions 22A, and connects the rear end of the second terminal holding portion 22A on one side to the rear end of the second terminal holding portion 22A on the other side.

[0060] The front end portion 21C and the rear end portion 22C have substantially the same configuration. Hereinafter, when explaining without particularly distinguishing between the front end portion 21C and the rear end portion 22C, they are referred to as the front and rear end portions 2C.

[0061] As shown in FIG. 10, in the fixed housing 2, a restraint space 6 in which a part (the protruding portion 36) of the movable housing 3 is restrained is formed. A plurality of restraint spaces 6 are formed in the fixed housing 2. The plurality of restraint spaces 6 are composed of a front restraint space 6A1, an intermediate restraint space 6B, and a rear restraint space 6A2. As shown in FIG. 6, in the front restraint space 6A1, the front protruding portion 36 of the first movable housing 31 is restrained. In the rear restraint space 6A2, the rear protruding portion 36 of the second movable housing 32 is restrained. In the intermediate restraint space 6B, the rear protruding portion 36 of the first movable housing 31 and the front protruding portion 36 of the second movable housing 32 are restrained.

[0062] The front restraint space 6A1 is formed in the front end portion 21C of the fixed housing 2. The rear restraint space 6A2 is formed in the rear end portion 22C of the fixed housing 2. The intermediate restraint space 6B is formed in the intermediate portion 2B of the fixed housing 2. The front end portion 21C, the rear end portion 22C, and the intermediate portion 2B function as a "restraint space forming portion" that forms the restraint space 6.

[0063] The front and rear end portions 2C have a pair of side walls 2C1 formed on both sides in the width direction and a top wall 2C2 connecting the pair of side walls 2C1. A restraint space 6 is formed below the top wall 2C2 between the pair of side walls 2C1.

[0064] The front and rear end portions 2C have a reinforcing wall 2C3. The reinforcing wall 2C3 constitutes the wall on the outer side in the front-rear direction of the restraint space 6. The lower surface of the reinforcing wall 2C3 is in the same plane as the lower surfaces of the pair of side walls 2C1 (FIG. 10).

[0065] (Press-fitting portion 2D for the fixing fitting 5) A press-fitting portion 2D into which a fixing fitting 5 is press-fitted is formed on each of a pair of side walls 2C1 at the front and rear end portions 2C. Note that the press-fitting portion 2D is not formed in the intermediate portion 2B. The fixing fitting 5 is press-fitted into the press-fitting portion 2D from above. In a state where the fixing fitting 5 is press-fitted into the press-fitting portion 2D, the substrate fixing portion 5B of the fixing fitting 5 does not protrude outward in the width direction beyond the outer surface in the width direction of the front and rear end portions 2C (FIG. 3).

[0066] (Bulging portion 2F) A bulging portion 2F is formed at the front and rear end portions 2C (FIG. 9). The bulging portion 2F is formed at the center in the width direction of the front and rear end portions 2C. At the position where the bulging portion 2F is formed, the height of the upper surface of the front and rear end portions 2C is slightly higher than that of other positions.

[0067] (Tail protection portion) The front and rear end portions 2C also function as a tail protection portion for protecting the substrate fixing portions 4A (tail portions) of the plurality of terminals 4. The front and rear end portions 2C protrude outward in the width direction with respect to the outer surface in the width direction of the terminal holding portion 2A. The outer surface in the width direction of the front end portion 21C and the outer surface in the width direction of the rear end portion 22C are formed on the same plane, and the substrate fixing portions 4A of the plurality of terminals 4 are accommodated inside the width direction with respect to this virtual plane (FIG. 3).

[0068] A boss 2G that is inserted into a hole formed in the substrate is formed at the front and rear end portions 2C.

[0069] (Intermediate portion) The intermediate portion 2B has a pair of side walls 2B1 formed on both sides in the width direction and a top wall 2B2 connecting the pair of side walls 2B1. An intermediate restraint space 6B is formed below the top wall 2B2 between the pair of side walls 2B1. The intermediate restraint space 6B is a space that is open downward and on both sides in the front and rear directions.

[0070] As shown in FIG. 9, the upper surfaces of the pair of side walls 2B1 of the intermediate portion 2B and the upper surface of the top wall 2B2 of the intermediate portion 2B form the same plane. The height of the upper surface of the intermediate portion 2B is the same as the height of the bulging portion 2F of the front and rear end portions 2C (FIG. 5).

[0071] Restricting surface The fixed housing 2 has a function of restricting the movable range of the movable housing 3 by abutting against the movable housing 3. That is, the fixed housing 2 is configured such that the movable housing 3 can abut against it, and has restricting surfaces 7 and 8 that restrict the movement of the movable housing 3 to a predetermined movable range (FIGS. 11 and 12).

[0072] The restricting surface 7 formed at the front and rear end portions 2C and the restricting surface 7 formed at the intermediate portion 2B are restricting surfaces 7 having substantially the same configuration. However, at the intermediate portion 2B, a restricting surface 7 facing forward and a restricting surface 7 facing rearward are formed. The restricting surface 7 facing forward can be abutted by the first movable housing 31, and the restricting surface 7 facing rearward can be abutted by the second movable housing 32.

[0073] Hereinafter, the specific configuration of the restricting surface 7 will be described.

[0074] The restricting surface 7 can be abutted by the lower portion 3C (including the protruding portion 36) of the movable housing 3.

[0075] As shown in FIG. 12, the restricting surface 7 has an upper restricting surface 71 against which the protruding portion 36 of the movable housing 3 abuts, a pair of width-direction restricting surfaces 72 against which the protruding portion 36 of the movable housing 3 abuts, and front-and-rear restricting surfaces 73 against which the lower portion 3C of the movable housing 3 abuts.

[0076] The upper restricting surface 71 is the lower surface of the top walls 2B2 and 2C2. The width-direction restricting surfaces 72 are the side surfaces of the pair of side walls 2B1 and 2C1. The front-and-rear restricting surfaces 73 are the end surfaces of the top walls 2B2 and 2C2.

[0077] (Front-and-rear restricting surface 73) As shown in FIG. 12, the front-and-rear restricting surface 73 has a central surface 73A, a pair of outer surfaces 73B, and a pair of concave surfaces 73C.

[0078] The central surface 73A is formed at the center in the width direction of the top walls 2B2 and 2C2. The central surface 73A is a plane with its normal direction oriented in the front-rear direction. When the movable housing 3 translates parallel in the front-rear direction from the normal position, the recess contact surface 39A (see FIG. 24) of the movable housing 3 contacts the central surface 73A.

[0079] The pair of outer surfaces 73B are formed at the outer ends in the width direction of the top walls 2B2 and 2C2. The pair of outer surfaces 73B are planes with their normal directions oriented inward in the front-rear direction. The positions of the outer surfaces 73B in the front-rear direction coincide with the central surface 73A. When the movable housing 3 translates parallel in the front-rear direction after translating parallel in either width direction from the normal position, the recess contact surface 39A of the movable housing 3 contacts either one of the pair of outer surfaces 73B and the central surface 73A (FIG. 24).

[0080] The concave surface 73C is formed between the central surface 73A and the outer surface 73B. The concave surface 73C is recessed in the front-rear direction (the direction in which the first arrangement space 21S or the second arrangement space 22S extends in the front-rear direction) with respect to the central surface 73A. The concave surface 73C enlarges the space through which the fitting portion 3B (upper portion 3B) of the movable housing 3 passes during connector manufacturing (see FIG. 20).

[0081] By forming the pair of concave surfaces 73C, a convex portion 2H that protrudes in the anti-protrusion direction (the direction approaching the main body portion 3A of the movable housing 3 in the front-rear direction) is formed between the pair of concave surfaces 73C.

[0082] As shown in FIG. 24, the concave surface 73C has a first surface 73C1 adjacent to the central surface 73A, a second surface 73C2 adjacent to the outer surface 73B, and a third surface 73C3 between the first surface 73C1 and the second surface 73C2. The first surface 73C1 faces outward in the width direction. The second surface 73C2 faces inward in the width direction and obliquely in the front-rear direction. The third surface 73C3 faces in the front-rear direction.

[0083] (Width direction limiting surface 72) The width direction limiting surface 72 has a pair of width direction surfaces 72A and a pair of inclined surfaces 72B.

[0084] The pair of width direction surfaces 72A of the width direction limiting surface 72 are surfaces located on the outer side in the width direction of the restraint space 6, and are planes with the normal direction facing the inner side in the width direction.

[0085] The pair of inclined surfaces 72B of the width direction limiting surface 72 are formed on the side closer to the terminal holding portion 2A than the pair of width direction surfaces 72A. The pair of inclined surfaces 72B obliquely connect the pair of width direction surfaces 72A and the inner side surface in the width direction of the side wall 2A1 of the terminal holding portion 2A. The pair of inclined surfaces 72B are planes with the normal direction facing the inner side in the width direction and the diagonal direction in the front-rear direction.

[0086] The inclined surface 72B of the width direction limiting surface 72 is located on the same plane as the second surface 73C2 of the concave surface 73C. As shown in FIG. 24, a recess is formed corresponding to the outer surface 73B between the inclined surface 72B of the width direction limiting surface 72 and the second surface 73C2 of the concave surface 73C. When the movable housing 3 moves parallel in any direction in the width direction after moving parallel in the front-rear direction after moving from the normal position, a part of the movable housing 3 enters this recess.

[0087] (Limiting surface 8 formed on the terminal holding portion 2A) As shown in FIG. 7, the limiting surface 8 is a limiting surface formed on the upper wall 2A2 of the terminal holding portion 2A, and the outer surface 3A2 in the width direction of the movable housing 3 can abut thereon.

[0088] ≪Movable housing 3≫ The movable housing 3 will be described with reference to FIGS. 13 to 17 and the like.

[0089] (Main body portion 3A) The movable housing 3 has a main body portion 3A. The main body portion 3A is substantially rectangular parallelepiped in shape, and has a pair of front and rear outer surfaces 3A1 with the normal direction facing outward in the front and rear direction, and a pair of widthwise outer surfaces 3A2 with the normal direction facing outward in the width direction. Further, the main body portion 3A has four connecting surfaces 3A3 that obliquely connect the front and rear outer surfaces 3A1 and the widthwise outer surfaces 3A2. The front and rear outer surfaces 3A1, the widthwise outer surfaces 3A2, and the connecting surfaces 3A3 each form the same plane over the entire vertical direction of the main body portion 3A. However, the front and rear outer surfaces 3A1 and the connecting surfaces 3A3 are formed only in the upper portion 3B of the movable housing 3 due to the influence of the formation of the entry recess 39.

[0090] An insertion space 3H into which a part (fitting portion) of the mating connector as the connection object is inserted is formed in the main body portion 3A. The insertion space 3H is opened upward. By forming the insertion space 3H in the main body portion 3A, a pair of front and rear walls 37 facing each other in the front and rear direction with the insertion space 3H interposed therebetween, and a pair of widthwise walls 33 facing each other in the width direction with the insertion space 3H interposed therebetween, are formed in the main body portion 3A.

[0091] The main body portion 3A has a first terminal arrangement portion 34 in which a part of the terminal 4 (movable-side held portion 4D, tip elastic portion 4E, contact portion 4F) is arranged. The first terminal arrangement portion 34 is composed of a terminal arrangement groove 34B formed on the inner surface in the width direction of the widthwise wall 33, and a terminal arrangement hole 34A penetrating in the vertical direction formed below the terminal arrangement groove 34B. The movable-side held portion 4D of the terminal 4 is arranged in the terminal arrangement hole 34A in a press-fitted and held state, and the tip elastic portion 4E and the contact portion 4F of the terminal 4 are arranged in the terminal arrangement groove 34B.

[0092] (Guide portion 35) The movable housing 3 has a pair of front and rear guide portions 35. The guide portion 35 guides the connection with the mating connector. The guide portions 35 project upward. A pair of guide portions 35 are formed in the front-rear direction. The guide portions 35 are formed at positions outside the insertion space 3H in the front-rear direction and are not formed at positions overlapping the insertion space 3H in the front-rear direction. On the other hand, the guide portions 35 are formed not only at positions overlapping the insertion space 3H in the width direction but also at positions outside the insertion space 3H in the width direction. The width dimension of the guide portions 35 matches the width dimension of the main body portion 3A of the movable housing 3. The guide portions 35 have a top surface 35A facing upward and inclined surfaces 35B connected to the side surfaces 3A1, 3A2, 3A3 of the main body portion 3A of the movable housing 3.

[0093] (Protrusion 36) The movable housing 3 has a pair of front-rear protrusions 36. The protrusion 36 (constrained portion) is a component for restricting the upward movement of the movable housing 3. The protrusion 36 is formed at the lower end of the movable housing 3. The protrusion 36 protrudes in a direction away from the main body portion 3A in the front-rear direction. Specifically, the front protrusion 36 protrudes with the front side as the protruding direction, and the rear protrusion 36 protrudes with the rear side as the protruding direction. The tip surface 36A of the protrusion 36 is located at a position away from the main body portion 3A in the front-rear direction compared to the outer surface 3A1 of the main body portion 3A in the front-rear direction. The protrusion 36 is disposed in the restraint space 6 of the fixed housing 2, and when the movable housing 3 moves upward, the upper surface 36B of the protrusion 36 abuts against the top walls 2B2, 2C2 of the fixed housing 2.

[0094] The tip surface 36A of the protrusion 36 is a surface formed at the end on the protruding direction side of the protrusion 36. A gate trace G is formed on the tip surface 36A.

[0095] The upper surface 36B of the protrusion 36 is a surface that abuts against the lower surface of the top walls 2B2, 2C2 when the movable housing 3 moves upward in parallel, and is a plane with the normal direction facing upward.

[0096] The lower surface 36C of the protrusion 36 is a surface that abuts against the substrate when the movable housing 3 moves downward in parallel, and is a surface with the normal direction facing downward.

[0097] The pair of side surfaces 36D of the protrusion 36 are surfaces that come into contact with the widthwise surface 72A formed by the side walls 2B1, 2C1 when the movable housing 3 moves parallel to the widthwise direction, and are flat surfaces whose normal direction faces outward in the widthwise direction. A curved surface 36E that smoothly connects the pair of side surfaces 36D and the tip surface 36A is formed between them.

[0098] (Entry recess 39) The movable housing 3 has an entrance recess 39 that forms an entrance space 9 into which a part of the fixed housing 2 (top walls 2B2, 2C2) can enter. By forming the entrance recess 39, the cross section (cross section perpendicular to the up-down direction) of the lower part 3C of the movable housing 3 is smaller than that of the upper part 3B of the movable housing 3.

[0099] In plan view, the entrance recess 39 forms a space (entrance space 9) on the side of the lower part 3C of the movable housing 3, which is inside in the front-rear direction and width direction from the side surfaces (front-rear outer side surface 3A1, width outer side surface 3A2, and connecting surface 3A3) of the main body 3A. The entrance recess 39 is formed on both front-rear sides of the movable housing 3.

[0100] The entrance recess 39 has a recess abutment surface 39A that abuts against the front and rear end portions 2C or the middle portion 2B (front and rear limiting surfaces 73) of the fixed housing 2 when the movable housing 3 moves in a direction perpendicular to the up and down direction.

[0101] The recess abutment surface 39A faces in a direction perpendicular to the up-down direction. The recess abutment surface 39A has a first surface 39A1, a pair of second surfaces 39A2, a pair of third surfaces 39A3, and a pair of fourth surfaces 39A4. The first surface 39A1 is a flat surface formed in the center of the movable housing 3 in the width direction and facing outward in the front-rear direction. The pair of second surfaces 39A2 are connected to the outer sides of the first surfaces 39A1 in the width direction. The pair of second surfaces 39A2 are flat surfaces facing outward in the width direction. The second surfaces 39A2 are flush with the side surfaces 36D of the protrusions 36. The pair of third surfaces 39A3 are formed on the outer sides in the width direction of the pair of second surfaces 39A2. The pair of third surfaces 39A3 are surfaces that face outward in the width direction and in a direction oblique to the front-rear direction. The pair of fourth surfaces 39A4 are connected to the outer sides of the pair of fourth surfaces 39A4 in the width direction. The pair of fourth surfaces 39A4 are surfaces facing the front-rear direction.

[0102] The front-to-rear dimension L3 of the lower part 3C of the movable housing 3 is smaller than the front-to-rear dimension L1 of the upper part 3B of the movable housing 3. On the other hand, the width dimension of the lower part 3C of the movable housing 3 is the same as the width dimension of the upper part 3B of the movable housing 3. However, the width dimension near the front end and near the rear end of the lower part 3C of the movable housing 3 (parts where the entrance recess 39 is formed) is smaller than the width dimension of the upper part 3B of the movable housing 3.

[0103] An upper surface 39B of the entry recess 39 is formed above the entry space 9. The upper surface 39B of the entry recess 39 is a plane having a downward normal direction. The upper surface 39B of the entry recess 39 is located below the bottom surface 3H1 of the insertion space 3H (FIG. 19). The entrance recess 39 is formed at a position that does not overlap with the entire vertical range of the pair of front-rear walls 37 that face each other in the front-rear direction with the insertion space 3H in between, thereby ensuring the strength of the front-rear walls 37.

[0104] (passing groove 38) The movable housing 3 has a passage groove 38 as a "recess." By forming the passing groove 38, when the upper part 3B of the movable housing 3 passes from bottom to top through the arrangement space 21S, 22S of the fixed housing 2 during manufacturing of the connector 1, a part of the fixed housing 2 (the convex part 2H) can pass through the passing groove 38 of the movable housing 3 (Figures 20 and 21).

[0105] The through groove 38 is formed on the outer surface 3A1 in the front-rear direction of the upper part 3B of the movable housing 3. The through groove 38 is located at the center in the width direction of the movable housing 3. The through groove 38 extends in the vertical direction with the front-rear direction as the groove depth direction and the width direction as the groove width direction. The cross-sectional shape perpendicular to the extending direction of the through groove 38 is rectangular. The through groove 38 is formed on both of the pair of outer surfaces in the front-rear direction of the movable housing 3.

[0106] As shown in FIG. 21, due to the formation of the through groove 38, the front-rear dimension L2 at the position (width direction position) where the through groove 38 of the upper part 3B of the movable housing 3 is formed is smaller than the front-rear dimension L1 of the upper part 3B of the movable housing 3. Therefore, although the front-rear dimension L1 of the upper part 3B of the movable housing 3 is larger than the front-rear distance D between the pair of upper walls 2B2 and 2C2 that one movable housing 3 abuts against, the upper part 3B (fitting part 3B) of the movable housing 3 can pass through the space between the pair of upper walls 2B2 and 2C2 in the vertical direction.

[0107] <Function and effect> Next, the function and effect of the present embodiment will be described.

[0108] ≪First aspect≫ In the present embodiment, the connector 1 includes a fixed housing 2, a first movable housing 31 having a first fitting part 3B that can be fitted with a first connection object (counter connector), and a second movable housing 32 having a second fitting part 3B that can be fitted with a second connection object (counter connector). Further, the connector 1 includes a first terminal 41 and a second terminal 42. The first terminal 41 has a first fixed-side held part 4B held by the fixed housing 2, a first movable-side held part 4D held by the first movable housing 31, and a first intermediate elastic part 4C located between the first fixed-side held part 4B and the first movable-side held part 4D. The second terminal 42 has a second fixed-side held part 4B held by the fixed housing 2, a second movable-side held part 4D held by the second movable housing 32, and a second intermediate elastic part 4C located between the second fixed-side held part 4B and the second movable-side held part 4D. The fixed housing 2 has a first terminal holding portion 21A that holds the first fixed side held portion 4B of the first terminal 41, and a second terminal holding portion 22A that holds the second fixed side held portion 4B of the second terminal 42.

[0109] Here, if the portion of the fixed housing 2 that holds the first terminal 41 (first terminal holding portion 21A) and the portion of the fixed housing 2 that holds the second terminal 42 (second terminal holding portion 22A) are separate, the relative positions of the first fixed side held portion 4B of the first terminal 41 and the second fixed side held portion 4B of the second terminal may shift from the predetermined position. In contrast, in this embodiment, the first terminal holding portion 21A and the second terminal holding portion 22A of the fixed housing 2 are integrally molded from resin, thereby preventing the relative positions of the first fixed side held portion 4B of the first terminal 41 and the second fixed side held portion 4B of the second terminal 42 from shifting from the predetermined position.

[0110] In addition, in this embodiment, a gate mark G (a mark formed at a position corresponding to the gate through which molten resin flows into the molding die) is formed in the intermediate portion 2B connecting the first terminal holding portion 21A and the second terminal holding portion 22A (Figure 11). Therefore, when molding the fixed housing 2, the molten resin can flow in from the portion located between the first terminal holding portion 21A and the second terminal holding portion 22A. This allows the molten resin to flow efficiently inside the molding die, preventing a decrease in the strength of the fixed housing 2 and distortion of the shape of the fixed housing 2. In particular, in this embodiment, the intermediate portion 2B of the fixed housing 2 does not have press-fit portions 2D into which the fixing metal fittings 5 are press-fitted, allowing the molten resin to flow smoothly from the intermediate portion 2B. Furthermore, since the fixing metal fittings 5 are arranged at the four corners of the fixed housing 2, the fixing of the fixed housing 2 to the substrate (mounting object) is sufficiently reinforced. It is preferable that the weld lines, which are the portions where the molten resins flowing inside the molding die collide with each other, be formed at the front and rear end portions 2C connecting the pair of terminal holding portions, because the front and rear end portions 2C have lower strength requirements than the terminal holding portion 2A.

[0111] Further, in the present embodiment, the fixed housing 2 has a housing space (a first arrangement space 21S and a second arrangement space 22S, FIG. 11) that penetrates the fixed housing 2 in the vertical direction and houses the first movable housing 31 and the second movable housing 32. The housing space (the first arrangement space 21S and the second arrangement space 22S) is divided by an intermediate connecting portion (the top wall 2B2 of the intermediate portion 2B) of the fixed housing 2 into a first housing space 21S that houses the first movable housing 31 and a second housing space 22S that houses the second movable housing 32. Therefore, it is possible to suppress the resin constituting the fixed housing 2 from shrinking during the molding of the fixed housing 2 and the fixed housing 2 from being deformed as a result of the shrinkage.

[0112] Further, in the present embodiment, the intermediate connecting portion (the top wall 2B2 of the intermediate portion 2B) restricts the upward movement of the first movable housing 31 and restricts the upward movement of the second movable housing 32 by contacting the second movable housing 32. Therefore, the intermediate connecting portion can function effectively.

[0113] Further, in the present embodiment, the upward movement of the first movable housing 31 is restricted by the first upper contact portion (the protruding portion 36) of the first movable housing 31 contacting the first upper restriction portion (the top walls 2B2 and 2C2) of the fixed housing 2, and the upward movement of the second movable housing 32 is restricted by the second upper contact portion (the protruding portion 36) of the second movable housing 32 contacting the second upper restriction portion (the top walls 2B2 and 2C2) of the fixed housing 2. Here, the first upper contact portion (the protruding portion 36) and the second upper contact portion (the protruding portion 36) protrude in the arrangement direction (the front-rear direction in the present embodiment), which is the direction in which the first movable housing 31 and the second movable housing 32 are arranged. Therefore, in the direction perpendicular to the arrangement direction among the directions orthogonal to the vertical direction (the width direction in the present embodiment), it is easy to make the connector 1 smaller.

[0114] <<Second aspect>> Next, the effects of the present embodiment will be described from other viewpoints.

[0115] In the present embodiment, as shown in FIG. 19, the connector 1 includes a fixed housing 2 and a movable housing 3. The movable housing 3 has a protruding portion 36 that protrudes in a protruding direction that is a direction perpendicular to the vertical direction. The fixed housing 2 has a constraint space forming portion (front and rear end portions 2C) that forms a constraint space 6 which is a space where the protruding portion 36 is constrained. The constraint space forming portion (front and rear end portions 2C) has a pair of side walls 2 C 1 located on the side of the protruding portion 36 and a top wall 2C2 located above the protruding portion 36. The top wall 2 C 2 restricts the upward movement of the movable housing 3 when the protruding portion 36 abuts thereon. Here, the constraint space forming portion (front and rear end portions 2C) is a reinforcing wall 2C3 located on the protruding direction side with respect to the protruding portion 36, and has a reinforcing wall 2C3 that connects the pair of side walls 2 C 1. Therefore, the reinforcing wall 2C3 reinforces the vicinity of the top wall 2C2 in the constraint space forming portion (front and rear end portions 2C), and suppresses damage to the constraint space forming portion (front and rear end portions 2C).

[0116] Also, in the present embodiment, even when the movable housing 3 moves parallel to the protruding direction (front and rear direction in the present embodiment) to the limit, the protruding portion 36 does not abut on the reinforcing wall 2C3 (FIG. 22). Therefore, the strength required for the reinforcing wall 2C3 itself can be low. Thus, the reinforcing wall 2C3 can be made thin, and the fixed housing 2 can be miniaturized.

[0117] Further, according to the present embodiment, it is effective when forming the constraint space forming portion (front and rear end portions 2C) low in the connector 1 in which a gate trace G (FIG. 13) is formed on the protruding end surface (tip end surface 36A) of the protruding portion 36. That is, in a movable housing 3 in which a gate mark G is formed on the protruding end surface 36A of the protruding portion 36, ensuring the size of the gate for injecting molten resin places a limit on how small the protruding portion 36 can be made. As a result, the constrained space 6 in which the protruding portion 36 is constrained also needs to be a certain size. One possible way to reduce the height of the constrained space forming portion (front and rear end portions 2C) of the fixed housing 2 while accommodating the protruding portion 36, which has a limit on how small it can be made, is to thin the top wall 2C2. However, if the top wall 2C2 is thinned, there is a risk that the constrained space forming portion will be damaged near the thinned top wall 2C2 if the movable housing 3 abuts hard against the fixed housing 2. Therefore, providing a reinforcing wall 2C3 suppresses damage to the constrained space forming portion.

[0118] <Third Aspect> Next, the effects of this embodiment will be described from another perspective.

[0119] In this embodiment, the connector 1 comprises a fixed housing 2, a first movable housing 31 having a first mating portion 3B that can be mated with a first connection object, a second movable housing 32 having a second mating portion 3B that can be mated with a second connection object, a first terminal 41, and a second terminal 42. The first movable housing 31 and the second movable housing 32 are arranged in a predetermined arrangement direction (front-rear direction) that is a direction perpendicular to the up-down direction. The first movable housing 31 has a first-side protrusion 36 (the rear protrusion 36 of the pair of front-rear protrusions 36 of the first movable housing 31) that protrudes in a direction perpendicular to the up-down direction and toward the second movable housing 32 (rear direction), and the second movable housing 32 has a second-side protrusion 36 (the front protrusion 36 of the pair of front-rear protrusions 36 of the second movable housing 32) that protrudes in a direction perpendicular to the up-down direction and toward the first movable housing 31 (front direction). The fixed housing 2 also has a constraint space forming portion (middle portion 2B) that forms a constraint space (intermediate constraint space 6B) that is a space in which both the first side protrusion 36 and the second side protrusion 36 are constrained. The constraint space forming portion 2B has a top wall 2B2 located above the first side protrusion 36 and the second side protrusion 36, and the top wall 2B2 restricts the upward movement of the first movable housing 31 and the second movable housing 32 when the first side protrusion 36 and the second side protrusion 36 abut against it.

[0120] Here, the restraint space 6B has a common restraint space in which both the first side protrusion 36 and the second side protrusion 36 can be positioned. Therefore, for example, when the first movable housing 31 moves in a direction (forward) away from the second movable housing 32, the second side protrusion 36 of the second movable housing 32 can move into the space where the first side protrusion 36 was located before the movement. Also, for example, when the second movable housing 32 moves in a direction away from the first movable housing, the first side protrusion 36 of the first movable housing 31 can move into the space where the second side protrusion 36 was located before the movement. In other words, at least a part of the constraint space 6B is shared by the first side protrusion 36 and the second side protrusion 36. This makes it easy to reduce the size of the connector in the arrangement direction.

[0121] In addition, in the present embodiment, in the normal state (the state shown in FIGS. 5 and 6), the first side protrusion 36 and the second side protrusion 36 are close to each other in the arrangement direction (front-rear direction). Specifically, the interval in the arrangement direction (front-rear direction) between the first side protrusion 36 and the second side protrusion 36 in the normal state is smaller than the distance that the first movable housing 31 can move in the direction (rear direction) in which the first movable housing 31 approaches the second movable housing 32 from the normal state, and is also smaller than the distance that the second movable housing 32 can move in the direction (front direction) in which the second movable housing 32 approaches the first movable housing 31 from the normal state. More specifically, the interval in the arrangement direction (front-rear direction) between the first side protrusion 36 and the second side protrusion 36 in the normal state is 1 / 5 or less of the distance that the first movable housing 31 can move in the direction (rear direction) in which the first movable housing 31 approaches the second movable housing 32 from the normal state, and is also 1 / 5 or less of the distance that the second movable housing 32 can move in the direction (front direction) in which the second movable housing 32 approaches the first movable housing 31 from the normal state. Therefore, it is even easier to miniaturize the connector 1 in the arrangement direction. In the present embodiment, the mating connector (not shown) as the connection object of the connector 1 includes a first fitting portion (not shown) as the first connection object and a second fitting portion (not shown) as the second connection object, and the mating connector is configured so that the first fitting portion and the second fitting portion do not displace relative to each other. In addition, in the present embodiment, as shown in FIG. 6, when the interval in the arrangement direction (front-rear direction) between the first side protrusion 36 and the second side protrusion 36 in the normal state is d, d>0, but d = 0 may also be possible. That is, in the normal state, the first side protrusion 36 and the second side protrusion 36 may be in contact with each other in the arrangement direction.

[0122] ≪Other aspects≫ Next, the effects of the present embodiment will be described from other viewpoints.

[0123] In the present embodiment, the connector 1 includes a fixed housing 2 and a movable housing 3. The movable housing 3 has an upper portion 3B and a lower portion 3C (FIGS. 14 and 15). The fixed housing 2 has portions (ceiling walls 2B2 and 2C2 as entry portions) disposed on the side of the lower portion 3C of the movable housing 3.

[0124] Here, the lower part 3C of the movable housing 3 is configured such that an access space 9 located below the upper part 3B is formed on the side of the lower part 3C. Then, when the movable housing 3 moves in a direction perpendicular to the vertical direction (the front-rear direction in this embodiment), the access parts (the top walls 2B2 and 2C2) can enter the access space 9 (FIG. 22). Therefore, different from the connector where the space located below the upper part 3B of the movable housing 3 and where a part of the fixed housing 2 can enter when the movable housing 3 moves in a direction perpendicular to the vertical direction is not formed on the side of the lower part 3C, while ensuring the size of the upper part 3B of the movable housing 3, the movable range of the movable housing 3 in the horizontal direction (the direction perpendicular to the vertical direction) can be increased. Note that in this embodiment, the upper part 3B of the movable housing 3 is the fitting part 3B, but it goes without saying that the above effect is not limited to the case where the upper part 3B is the fitting part 3B.

[0125] Also, in this embodiment, the movable housing 3 has a protruding part 36 that protrudes in the protruding direction, which is a direction perpendicular to the vertical direction. And the access parts (the top walls 2B2 and 2C2) are "upper limit parts" that limit the upward movement of the movable housing 3 when the protruding part 36 abuts against the access parts (the top walls 2B2 and 2C2). Therefore, according to this embodiment, in the connector 1 in which the fixed housing 2 has an "upper limit part" for limiting the upward movement of the movable housing 3, while ensuring the size of the upper part 3B of the movable housing 3, the displacement amount of the movable housing 3 in the horizontal direction can be increased.

[0126] Also, in this embodiment, the fixed housing 2 has an opposing part (the top walls 2B2 and 2C2) that opposes the access part (the top walls 2B2 and 2C2) in the protruding direction. A passage space (arrangement spaces 21S and 22S) is formed between the access part (the top walls 2B2 and 2C2) and the opposing part (the top walls 2B2 and 2C2), and the passage space (arrangement spaces 21S and 22S) is configured such that the upper part 3B of the movable housing 3 can pass through in the vertical direction. Therefore, in the connector 1 where it is necessary to pass the passage spaces (arrangement spaces 21S and 22S) formed by the fixed housing 2 through the upper portion 3B of the movable housing 3, the horizontal displacement amount of the movable housing 3 can be increased while ensuring the size of the upper portion 3B of the movable housing 3.

[0127] Also, in the present embodiment, the entry portions (ceiling walls 2B2 and 2C2) have convex portions 2H protruding in the first direction inward (a direction perpendicular to the vertical direction and approaching the center side of the movable housing 3). The upper portion 3B of the movable housing 3 has a concave portion (passage groove 38) recessed inward in the first direction. The concave portion (passage groove 38) is configured such that the convex portion 2H can pass through in the vertical direction. Since the convex portion 2H of the entry portions (ceiling walls 2B2 and 2C2) functions as an "upper limit portion", the upward movement of the movable housing 3 is more reliably restricted. And the convex portion 2H passes through the concave portion (passage groove 38) of the upper portion 3B of the movable housing 3 during connector assembly and can enter the entry space 9 after assembly (FIGS. 20 and 21). Furthermore, although the upper portion 3B of the movable housing 3 has a concave portion (passage groove 38), a portion where the concave portion (passage groove 38) is not formed remains, so the size (first direction dimension) of the upper portion 3B of the movable housing 3 can be ensured. In particular, in the present embodiment, the thickness of the peripheral wall (especially the front-rear direction wall 37) can be increased while ensuring the size of the insertion space 3H formed in the upper portion 3B (fitting portion 3B) of the movable housing 3, so the strength of the peripheral wall can be improved.

[0128] Also, in the present embodiment, when the movable housing 3 moves to the limit in the anti-protrusion direction, the protruding portion 36 faces only the convex portion 2H of the entry portions (ceiling walls 2B2 and 2C2) in the vertical direction (FIG. 23). For this reason, the movable range of the movable housing 3 in the anti-protrusion direction can be increased. From the perspective of increasing the movable range of the movable housing 3 in the anti-projecting direction, it is not always necessary for the protruding portion 36 to face only the convex portion 2H in the vertical direction when the movable housing 3 moves to the limit in the anti-projecting direction. For example, when the protruding portion 36 and the entry portion (the top walls 2B2, 2C2) are projected onto a plane perpendicular to the vertical direction, it means that more than 80% of the overlapping portion of the two is the overlapping portion of the protruding portion 36 and the convex portion 2H when projected onto a plane perpendicular to the vertical direction. However, it is more preferable that 100% of the overlapping portion of the protruding portion 36 and the entry portion (the top walls 2B2, 2C2) when projected onto a plane perpendicular to the vertical direction is the overlapping portion of the protruding portion 36 and the convex portion 2H when projected onto a plane perpendicular to the vertical direction.

[0129] 〔Supplementary Explanation〕 In the above embodiment, an example (so-called parallel connection) where the substrate and the mating substrate are arranged in parallel with each other with the connector pair therebetween in the connected state of the connector 1 and the mating connector has been described, but the present disclosure is not limited thereto. For example, a vertical connection or a horizontal connection may be used.

[0130] Also, in the above embodiment, the housing holds the terminals by press-fitting, but holding by insert molding may also be used.

[0131] Also, in the above embodiment, the intermediate portion of the terminal is an intermediate elastic portion, but the intermediate portion of the present disclosure is not limited thereto. For example, the terminal may be separately configured by a first portion having a fixed-side held portion and a second portion having a movable-side held portion, and the contacting portion between the first portion and the second portion may be the "intermediate portion".

[0132] Also, in the above embodiment, the connector includes two movable housings, but the present disclosure is not limited thereto. The number of movable housings included in the connector may be one or three or more.

[0133] In the above-described embodiments, the housings 2 and 3 are integrally molded from resin, but the housings of the present disclosure are not limited to this. For example, the housings may be made of a combination of resin and metal. Specifically, the upper limiting portion of the fixed housing may be made of a metal member.

[0134] In addition, in the above embodiment, the passage grooves 38 as recesses are formed on both of the pair of front-rear direction outer surfaces of the movable housing 3, but the present disclosure is not limited to this. For example, the recesses may be formed only on one of the front-rear direction outer surfaces 3A1 of the movable housing 3.

[0135] In addition, in the above embodiment, a plurality of terminals are held in one movable housing, but the present disclosure is not limited to this. One movable housing may hold only one terminal.

[0136] Furthermore, in the above embodiment, the intermediate portion 2B has an intermediate connecting portion (top wall 2B2 of the intermediate portion 2B), but it is not necessary to have an intermediate connecting portion. [Explanation of symbols]
