Here, if the portion along the surface of the held portion is adjacent to the elastic portion, the portion along the surface of the housing is held when the displaced portion is displaced with respect to the held portion and the elastic portion is elastically deformed. There is a concern that a load will be applied to the portion to be held and the portion along the surface of the held portion will be peeled off from the housing.

Therefore, in this aspect, the portion along the surface adjacent to the elastic portion has a peeling direction covering surface. The peeling direction covering surface means a surface coated on the housing, and the peeling direction component of the normal of the surface is a positive surface.
Therefore, when a force for peeling the portion along the surface (that is, a force in the peeling direction) is applied to the portion along the surface, the peeling direction covering surface of the portion along the surface acts as a normal force from the housing in the peeling direction. Receives forces with opposite components. As a result, the portion along the surface is suppressed from peeling from the housing.

The terminal has a fixed-side held portion held in the fixed housing by insert molding, and a movable-side held portion that is configured to be displaceable with respect to the fixed-side held portion and is held in the movable housing. It has an elastically deformable intermediate elastic portion located between the fixed side held portion and the movable side held portion, and the fixed side held portion extends along the surface of the fixed housing. A portion that is present and is configured to include a surface along a surface that has a surface exposed from the fixed housing, and the surface along the portion is a surface that is adjacent to the intermediate elastic portion and is covered by the fixed housing. Therefore, it has a peeling direction covering surface in which the peeling direction component of the normal of the surface is a positive surface.

In this aspect, the connector includes a fixed housing configured to be fixed to a fixed object such as a substrate, a movable housing configured to be displaceable to the fixed housing, and terminals. The terminal is elastically deformable located between the fixed side held portion held by the fixed housing, the movable side held portion held by the movable housing, and the fixed side held portion and the movable side held portion. It has an intermediate elastic portion. Due to the elastic deformation of the intermediate elastic portion, the movable side held portion is displaced with respect to the fixed side held portion.

Further, the fixed-side held portion is configured to include a portion along the surface. The surface-aligned portion means a portion extending along the surface of the fixed housing and having a surface exposed from the fixed housing.
Here, if the portion along the surface of the fixed side held portion is adjacent to the intermediate elastic portion, when the movable side held portion is displaced with respect to the fixed side held portion and the intermediate elastic portion is elastically deformed, Of the fixed housing, a load is applied to the portion along the surface where the portion along the surface is held, and there is a concern that the portion along the surface of the fixed side held portion may peel off from the fixed housing.

Therefore, in this aspect, the portion along the surface adjacent to the intermediate elastic portion has a peeling direction covering surface. The peeling direction coated surface means a surface coated on the fixed housing, and the peeling direction component of the normal of the surface is a positive surface.
Therefore, when a force that peels off the portion along the surface (that is, a force in the peeling direction) is applied to the portion along the surface, the covering surface in the peeling direction along the surface acts as a normal force from the fixed housing in the peeling direction. Receives a force that has a component in the opposite direction. As a result, the portion along the surface is suppressed from peeling from the fixed housing.

The connector according to the third aspect is a wall in which the fixed housing holds the fixed side held portion and forms a storage space in which all or a part of the movable housing is housed in the second aspect. It has a terminal holding wall, the portion along the surface extends along the inner surface which is the surface of the terminal holding wall facing the accommodation space, and the fixed side held portion is only the portion along the surface. Consists of.

In this aspect, the fixed housing has a terminal holding wall, which is a wall that holds the fixed side held portion and forms a storage space in which all or part of the movable housing is housed.
Then, the portion along the surface extends along the inner surface (the surface facing the accommodation space) of the terminal holding wall, and the fixed-side held portion is composed of only the portion along the surface. That is, the fixed-side held portion is composed of only the portion along the surface extending along the inner surface of the terminal holding wall.
Therefore, only the portion near the inner side surface of the terminal holding wall is responsible for holding the fixed side held portion. Therefore, the wall thickness of the terminal holding wall can be reduced while maintaining the holding force of the fixed side held portion.

The connector according to the fourth aspect, in the second or third aspect, the fixed housing holds the fixed side held portion and forms a storage space in which all or a part of the movable housing is housed. It has a terminal holding wall which is a wall to be formed, and a portion along the surface extends along an inner surface surface of the terminal holding wall facing the accommodation space, and the terminal serves as the fixing object. It has a horizontal portion configured along the substrate and a curved portion connecting the horizontal portion and the surface-along portion.

In this aspect, the fixed housing has a terminal holding wall, which is a wall that holds the fixed side held portion and forms a storage space in which all or part of the movable housing is housed.
Then, the portion along the surface extends along the inner surface (the surface facing the accommodation space) of the terminal holding wall, and the fixed-side held portion is composed of only the portion along the surface. That is, the fixed-side held portion is composed of only the portion along the surface extending along the inner surface of the terminal holding wall.

Further, the terminal has a horizontal portion configured along the substrate as a fixing object and a curved portion connecting the horizontal portion and the surface-along portion.
Therefore, the horizontal portion and the curved portion of the terminal come into contact with or close to the surface of the substrate, and can be used for soldering to the substrate. Then, since the curved portion of the terminal is formed near the inner side surface of the terminal holding wall in a plan view (viewed from the direction perpendicular to the substrate), the terminal is soldered to the substrate close to the accommodation space. It becomes possible. As a result, the mounting strength of the connector can be improved.

It has a terminal holding wall that is a wall forming a space, the portion along the surface extends along the inner surface of the terminal holding wall facing the accommodation space, and the fixed side held portion extends. The terminal is composed of only the portion along the surface, and the terminal has a horizontal portion configured along the substrate as the object to be fixed, and a curved portion connecting the horizontal portion and the portion along the surface. However, a part of the horizontal portion protrudes from the terminal holding wall on the side opposite to the accommodation space when viewed from a direction perpendicular to the substrate.

In this aspect, a part of the horizontal portion protrudes from the terminal holding wall on the side opposite to the accommodation space when viewed from the direction perpendicular to the substrate.
Therefore, it is easy to confirm whether or not the connector is properly mounted.

In the connector according to the sixth aspect, in any of the second to fifth aspects, the intermediate elastic portion approaches the first extending portion extending in a direction away from the substrate as the fixing object and the substrate. It has a second extending portion extending in a direction and a folded portion connecting the first extending portion and the second extending portion, and both the first extending portion and the along-plane portion are described above.

It has a folded portion that connects the portions.

Then, both the first extending portion and the along-plane portion extend linearly in the direction perpendicular to the substrate and are linearly connected to each other.
For this reason, in a connector that requires miniaturization, it is necessary to arrange the intermediate elastic portion of the terminal in a limited space, but the intermediate elastic portion of the terminal (the first extending portion or the folded portion that is a part of the terminal) Can be efficiently arranged by utilizing the space above the portion of the fixed housing that holds the fixed-side held portion.
However, since there is no bent terminal between the portion along the surface of the fixed side held portion and the folded portion of the intermediate elastic portion, if the intermediate elastic portion is elastically deformed, the portion along the surface A large load is likely to be applied to the portion where the is held. However, in this aspect, as described in the description of the first aspect, since the portion along the surface has a peeling direction covering surface, the peeling of the portion along the surface is suppressed.

In any of the second to sixth aspects, the connector according to the seventh aspect has the movable side held portion held in the movable housing by insert molding, and the movable side held portion is held in the movable housing. The portion along the surface extending along the surface of the movable housing, including the portion along the surface having the surface exposed from the movable housing, and the portion along the surface of the movable side held portion is adjacent to the intermediate elastic portion. At the same time, it has a peeling direction covering surface which is a surface covered by the movable housing and in which the peeling direction component of the normal of the surface is a positive surface.

The surface-lined portion means a portion extending along the surface of the movable housing and having a surface exposed from the movable housing.
Here, if the portion along the surface of the movable side held portion is adjacent to the intermediate elastic portion, when the movable side held portion is displaced with respect to the fixed side held portion and the intermediate elastic portion is elastically deformed, Of the movable housing, a load is applied to the portion along the surface where the portion along the surface is held, and there is a concern that the portion along the surface of the movable side held portion may peel off from the movable housing.

Therefore, in this aspect, the portion along the surface of the movable side held portion has a peeling direction covering surface. The peeling direction covering surface means a surface coated on the movable housing, and the peeling direction component of the normal of the surface is a positive surface.
Therefore, when a force for peeling the portion along the surface (that is, a force in the peeling direction) is applied to the portion along the surface, the peeling direction covering surface of the portion along the surface acts as a normal force from the movable housing in the peeling direction. Receives a force that has a component in the opposite direction. As a result, the portion along the surface of the movable side held portion is suppressed from peeling from the movable housing.

It has a pair of horizontal contact surfaces to limit, and the portion along the surface of the fixed side held portion is exposed to the horizontal contact surface of the fixed housing and along the surface of the movable side held portion. The portion is exposed to the horizontal contact surface of the movable housing.

In this aspect, the fixed housing and the movable housing have a pair of horizontal contact surfaces that limit the range of motion along the substrate as the object of fixation of the movable housing to the fixed housing by abutting against each other.
The portion along the surface of the fixed side held portion is exposed to the horizontal contact surface of the fixed housing, and the portion along the surface of the movable side held portion is exposed to the horizontal contact surface of the movable housing.
Therefore, the movable housing can be displaced with respect to the fixed housing to a position where the portion along the surface of the fixed side held portion and the portion along the surface of the movable side held portion come into contact with each other. It is possible to secure a large range of motion in the direction in which the contact surfaces face each other.

According to the present invention, in a connector having a structure in which a terminal having an elastic portion is held in a housing by insert molding, a held portion (a portion held by the housing) is configured including a portion along a surface adjacent to the elastic portion.

The curved portion 34B and the inner portion 34C of the movable side held portion 34 are held by the first movable housing 50 so that the entire circumference (planes in four directions) thereof is covered with resin. On the other hand, as shown in FIG. 30, the lower portion 34A of the movable side held portion 34 has an outer surface (exposed surface 37A) in the inter-row direction exposed from the resin and other surfaces (inner in the inter-row direction and pitch direction). It is held by the first movable housing 50 so that the surfaces in three directions with both sides) are covered with the resin.

The intermediate elastic portion 33 is configured to be elastically deformable. As a result, displacement of the movable housings 50 and 60 with respect to the fixed housing 20 is allowed.
Specifically, as shown in FIG. 12, the intermediate elastic portion 33 includes a first straight portion 33A extending upward from the fixed-side held portion 32 and a first curved portion bent so as to be convex upward. It has 33B, a second straight portion 33C extending downward and inward in the inter-row direction in an oblique direction, and a second curved portion 33D that bends the other end 30S side downward from the second straight portion 33C in this order.

Further, the terminal 30 has a contact portion 36 that comes into contact with the mating terminal 70 of the mating connector 10 (FIGS. 5 and 14) inserted from above the connector. The contact portion 36 is located on the other end 30S side of the movable side held portion 34. The contact portion 36 has a curved shape that is convex inward in the inter-row direction, and the convex portion of this curved shape contacts the mating connector 10.

Further, the terminal 30 has a tip elastic portion 35 for making the contact portion 36 displaceable with respect to the movable housings 50 and 60.
The tip elastic portion 35 elastically deforms when the mating connector 10 comes into contact with the contact portion 36. The tip elastic portion 35 is located between the movable side held portion 34 and the contact portion 36. The tip elastic portion 35 first extends inward in the inter-row direction from one end 30K side to the other end 30S side, and then extends substantially upward (upward and diagonally inward in the inter-row direction).

Further, the terminal 30 has a curved portion 36M between the contact portion 36 and the tip elastic portion 35 so that the contact portion 36 projects inward in the inter-row direction.

(Fixed side member)
The fixed housing 20 and the reinforcing metal fittings formed of the resin constitute the fixed side members 20 and 40.

As shown in FIG. 2, the fixed side members 20 and 40 have peripheral walls 21 and 22.
The peripheral walls 21 and 22 are composed of a pair of pitch direction walls 22 located on both sides in the pitch direction and a pair of interrow direction walls 21 located on both sides in the interrow direction.

A storage space 26 in which a part of the movable housings 50 and 60 is housed is formed inside the peripheral walls 21 and 22 so as to be surrounded by the peripheral walls 21 and 22 (see FIG. 24). A part of the movable housings 50 and 60 is constrained in the accommodation space 26 of the fixed side members 20 and 40, so that the range of motion of the movable housings 50 and 60 in the XY directions (horizontal connector direction, direction along the substrate) is increased. Is regulated. The accommodation space 26 is open downward.

As shown in FIGS. 12, 13, and 30, the fixed-side held portion 32 of the terminal 30 is held in a buried state in the inter-row direction wall 21.
The thickness of the lower portion 21L of the inter-row direction wall 21 is increased so as to project inward in the inter-row direction with respect to the upper portion 21U of the inter-row direction wall 21. Then, the fixed side held portion 32 of the terminal 30 is held in the lower portion 21L of the inter-row direction wall 21. As a result, the lower portion of the first straight line portion 33A of the intermediate elastic portion 33 of the terminal 30 is located inside the upper portion 21U of the inter-row direction wall 21 in the inter-row direction.

The upper end of the inter-row direction wall 21 is formed below the upper end (first curved portion 33B) of the intermediate elastic portion 33. As a result, when the movable housings 50 and 60 are displaced in the inter-row direction and the intermediate elastic portion 33 of the terminal 30 is deformed, the intermediate elastic portion 33 is prevented from interfering with the inter-row direction wall 21.

The upper end of the pitch direction wall 22 is formed above the upper end of the inter-row direction wall 21. By forming the pitch direction wall 22 high, the strength of the fixed housing 20 is improved.

The upper end of the pitch direction wall 22 is formed below the upper end (first curved portion 33B) of the intermediate elastic portion 33 of the terminal 30. As a result, the length of the intermediate elastic portion 33 is secured, and the expansion of the vertical dimension of the fixed housing 20 is suppressed.

As shown in FIG. 2, a vertical groove 23 extending in the vertical direction is formed on the outer surface of the pitch direction wall 22 in the pitch direction. The upper and lower grooves 23 are formed with the inside in the pitch direction as the depth direction. A part of the reinforcing metal fitting 40 is exposed from the portion of the pitch direction wall 22 where the upper and lower grooves 23 are formed. The width of the vertical groove 23 (dimension in the inter-row direction) is larger than the width of the carrier cutting portion 46 (dimension in the inter-row direction) described later.

As shown in FIG. 1, two reinforcing metal fittings 40 are provided for one connector 100. One reinforcing metal fitting 40 is located on one side of the fixed housing 20 in the pitch direction, and the other reinforcing metal fitting 40 is located on the other side of the fixed housing 20 in the pitch direction. The two reinforcing metal fittings 40 have the same structure as each other.

The reinforcing metal fitting 40 is manufactured by subjecting a plate material to punching and bending, and includes a flat plate-shaped portion and a bent portion (bent portion).
Specifically, as shown in FIGS. 17 and 18, the reinforcing metal fittings 40 are the flat plate-shaped first flat plate portion 40A, the second flat plate portion 40B, the third flat plate portion 40C, and the fourth flat plate portion 40D. It has a first curved portion 41A, a second curved portion 41B, and a third curved portion 41C connecting the flat plate portions 40A, 40B, 40C, and 40D. Each of the curved portions 41A, 41B, and 41C is a portion that is bent by approximately 90 degrees in the plate thickness direction.

The first flat plate portion 40A constitutes a part of the pitch direction wall 22 of the fixed side members 20 and 40.

The second curved portion 41B is bent inward in the pitch direction, and the third flat plate portion 40C is located inward in the pitch direction with respect to the first flat plate portion 40A.

The third flat plate portion 40C constitutes a part of the pitch direction wall 22 and the inter-row direction wall 21 of the fixed side members 20 and 40. The plate thickness direction of the third flat plate portion 40C is directed to the row-to-row direction. The entire third flat plate portion 40C is buried in the fixed housing 20 and is not exposed from the fixed housing 20.

The width (dimension in the pitch direction) of the third flat plate portion 40C is expanded so that the outer end portion of the third flat plate portion 40C in the pitch direction is located outside in the pitch direction at the lower end thereof. Therefore, the width (dimension in the pitch direction) of the third flat plate portion 40C is larger at the lower end than at the same height as the second curved portion 41B. As shown in FIG. 20, the outer end in the pitch direction at the lower end of the third flat plate portion 40C is located outside the pitch direction of the outer surface 40A1 of the first flat plate portion 40A in the pitch direction.

The height of the upper end of the C-shaped portion 47 is lower than the height of the inter-row direction wall 21 of the fixed side members 20 and 40, but the height of the upper end of the extension portion 48 is between the rows of the fixed side members 20 and 40. It is higher than the height of the direction wall 21.

Since the reinforcing metal fitting 40 is integrated with the fixed housing 20 by insert molding, it does not have a means (protrusion for press fitting) for being press-fitted into the fixed housing 20.

At the time of insert molding, the reinforcing metal fitting 40 is connected to the carrier (in other words, the reinforcing metal fitting 40 is not separated from the material), and the reinforcing metal fitting 40 is separated from the carrier after insert molding.
Specifically, the tip of the long portion 45C of the second flat plate portion 40B of the reinforcing metal fitting 40 is a portion connected to the carrier. That is, the tip of the long portion 45C is the carrier cutting portion 46. The carrier cutting portion 46 refers to a portion formed when a portion connecting the reinforcing metal fitting 40 and the carrier is cut after insert molding.
Two carrier cutting portions 46 are formed for one reinforcing metal fitting 40. The two carrier cutting portions 46 are formed at positions symmetrical with respect to the center in the width direction (center in the inter-row direction) of the reinforcing metal fittings.

(Mother connector)
5 and 14 show the mating connector 10 as the “object to be connected”.
As shown in FIGS. 4 to 6, the mating connector 10 as the “object to be connected” fits into the connector 100. As shown in FIG. 14, the mating connector 10 includes a plurality of mating terminals 70 and a mating housing 80.

The mating housing 80 includes a base 81 arranged along a mating substrate (not shown), and an insertion portion 82 protruding from the base 81 toward the connector 100. The insertion portion 82 is inserted into the inserted portion 66 of the second movable housing 60. Arrangement grooves (not shown) in which the contact portion 73 of the mating terminal 70 is arranged are formed on one side of the insertion portion 82 in the inter-row direction and the other side in the inter-row direction. The arrangement groove extends linearly in the vertical direction of the connector.

The mating terminal 70 has a mounting portion 71, a first buried portion 72, a contact portion 73, and a second buried portion 74 from one end side to the other end side.

The mounting portion 71 is fixed to the surface of the mating board by soldering. The mounting portion 71 extends linearly inward in the inter-row direction from one end side to the other end side.

The first buried portion 72 is buried in the mating housing 80. A first curved portion 75A is formed between the mounting portion 71 and the first buried portion 72.

In the fifth curved portion 75E, the extending direction inside in the inter-row direction is bent toward the lower side of the connector. The tip surface (the surface formed by cutting the plate material) of the second buried portion 74 is exposed from the mating housing 80 toward the lower side of the connector.

The plurality of mating terminals 70 and mating housing 80 are integrated by insert molding. Therefore, the mating terminal 70 does not have a means (protrusion for press fitting) for press-fitting the mating terminal 70 into the mating housing 80.

The mating terminal 70 is made by subjecting a plate material to punching and bending. The mating terminal 70 has a plurality of bent portions of the plate material, but the plate thickness direction of the mating terminal 70 faces the direction in the plane (in the ZX plane) orthogonal to the pitch direction in all the portions of the mating terminal 70. ..

<Effect>
Next, the action and effect of this embodiment will be described.

In this embodiment, as shown in FIGS. 11 and 13, the connector 100 includes a fixed housing 20 as a “housing” and terminals 30. The terminal 30 is configured to be displaceable with respect to the fixed-side held portion 32 as a "held portion" held in the housing (fixed housing 20) by insert molding and the held portion (fixed-side held portion 32). The elastically deformable "elasticity" located between the movable side held portion 34 as the "displaced portion" and the held portion (fixed side held portion 32) and the displaced portion (movable side held portion 34). It has an intermediate elastic portion 33 as a portion.
Further, the held portion (fixed side held portion 32) includes a portion along the surface (upper portion 32A of the fixed side held portion 32). "Along the surface" means a portion extending along the surface of the housing and having a surface exposed from the housing.
Here, if the portion along the surface of the held portion (fixed side held portion 32) (upper portion 32A of the fixed side held portion 32) is adjacent to the elastic portion (intermediate elastic portion 33), the displacement portion (movable). When the side-held portion 34) is displaced with respect to the held portion (fixed side-held portion 32) and the elastic portion (intermediate elastic portion 33) is elastically deformed, the housing (fixed housing 20) is along the surface. A load is applied to the portion where the portion (upper portion 32A of the fixed side held portion 32) is held, and the portion along the surface of the held portion (fixed side held portion 32) (upper portion 32A of the fixed side held portion 32) is applied. ) May peel off from the housing (fixed housing 20).
Therefore, in the present embodiment, as shown in FIG. 30, the portion along the surface (the upper portion 32A of the fixed side held portion 32) adjacent to the elastic portion (intermediate elastic portion 33) has the peeling direction covering surface 37B. The "peeling direction coated surface" means a surface covered with a housing and a surface having a positive peeling direction component of the normal of the surface.
Therefore, a force that peels off the surface-side portion (upper portion 32A of the fixed-side held portion 32) (that is, a force in the peeling direction, a force inward in the inter-row direction in the present embodiment) is applied to the surface-side portion (fixed). When applied to the upper portion 32A of the side-held portion 32), the peeling direction covering surface 37B of the portion along the surface (the upper portion 32A of the fixed side-held portion 32) acts as a normal force from the housing (fixed housing 20). , Receives a force having a component in the direction opposite to the peeling direction. As a result, the portion along the surface (the upper portion 32A of the fixed side held portion 32) is suppressed from peeling from the housing (fixed housing 20).
From the viewpoint of suppressing peeling, the ratio of the width W2 of the exposed surface 37A to the width W1 of the side portion (upper portion 32A of the fixed side held portion 32) is preferably 90% or less, more preferably 80% or less. Is.

Further, in the present embodiment, the connector 100 includes movable housings 50 and 60 as "housings" and terminals 30. The terminal 30 can be displaced with respect to the movable side held portion 34 as a "held portion" held in the housing (movable housings 50 and 60) by insert molding and the held portion (movable side held portion 34). It is elastically deformable located between the fixed-side held portion 32 as a "displacement portion", the held portion (movable side held portion 34), and the displacement portion (fixed-side held portion 32). It has an intermediate elastic portion 33 as an "elastic portion".
Further, the held portion (movable side held portion 34) includes a portion along the surface (lower portion 34A of the movable side held portion 34). "Along the surface" means a portion extending along the surface of the housing and having a surface exposed from the housing.
Here, when the portion along the surface (lower portion 34A) of the held portion (movable side held portion 34) is adjacent to the elastic portion (intermediate elastic portion 33), the displacement portion (fixed side held portion 32) becomes. When the elastic portion (intermediate elastic portion 33) is elastically deformed due to displacement with respect to the held portion (movable side held portion 34), the portion along the surface (movable side covering) of the housings (movable housings 50 and 60) A load is applied to the portion where the lower portion 34A) of the holding portion 34 is held, and the portion along the surface (lower portion 34A) of the held portion (movable side held portion 34) is separated from the housing (movable housings 50 and 60). There is a concern that it will be done.
Therefore, in the present embodiment, the portion along the surface (lower portion 34A of the movable side held portion 34) adjacent to the elastic portion (intermediate elastic portion 33) has the peeling direction covering surface 37B. The "peeling direction coated surface" means a surface covered with a housing and a surface having a positive peeling direction component of the normal of the surface.
Therefore, a force (that is, a force in the peeling direction, a force outward in the inter-row direction in the present embodiment) that peels off the portion along the surface (the lower portion 34A of the movable side held portion 34) is the portion along the surface (movable). When joining the lower portion 34A of the side-held portion 34), the peeling direction covering surface 37B of the portion along the surface (lower portion 34A of the movable side-held portion 34) is perpendicular to the housing (movable housings 50 and 60). As a drag force, it receives a force having a component in the direction opposite to the peeling direction. As a result, it is suppressed that the portion along the surface (the lower portion 34A of the movable side held portion 34) is separated from the housing (movable housings 50 and 60).

Further, in the present embodiment, the fixed housing 20 in which the connector 100 is configured to be fixed to a fixed object such as a substrate, and the movable housings 50 and 60 to be displaced to the fixed housing 20 are used. A terminal 30 is provided. The terminal 30 includes a fixed side held portion 32 held by the fixed housing 20, a movable side held portion 34 held by the movable housings 50 and 60, and a fixed side held portion 32 and a movable side held portion 34. It has an elastically deformable intermediate elastic portion 33 located between the two. As the intermediate elastic portion 33 elastically deforms, the movable side held portion 34 is displaced with respect to the fixed side held portion 32.
Further, the fixed-side held portion 32 includes a portion along the surface (upper portion 32A).
Here, when the portion along the surface (upper portion 32A) of the fixed side held portion 32 is adjacent to the intermediate elastic portion 33, the movable side held portion 34 is displaced with respect to the fixed side held portion 32 and is intermediate. When the elastic portion 33 is elastically deformed, a load is applied to the portion of the fixed housing 20 that holds the portion along the surface (the upper portion 32A of the fixed side held portion 32), and along the surface of the fixed side held portion 32. There is a concern that the portion (upper portion 32A) may peel off from the fixed housing 20.
Therefore, in the present embodiment, the portion along the surface adjacent to the intermediate elastic portion 33 (the upper portion 32A of the fixed side held portion 32) has the peeling direction covering surface 37B.
Therefore, a force that peels off the surface-side portion (upper portion 32A of the fixed-side held portion 32) (that is, a force in the peeling direction, a force inward in the inter-row direction in the present embodiment) is applied to the surface-side portion (fixed). When joining the upper portion 32A of the side-held portion 32), the peeling direction covering surface 37B along the surface (upper portion 32A of the fixed side-held portion 32) acts as a normal force from the fixed housing 20 in the peeling direction. Receives a force that has a component in the opposite direction. As a result, the portion along the surface (the upper portion 32A of the fixed side held portion 32) is suppressed from peeling from the fixed housing 20.

Further, in the present embodiment, as shown in FIG. 13, the fixed housing 20 holds the fixed side held portion 32 and forms a storage space 26 in which all or a part of the movable housings 50 and 60 are housed. It has a terminal holding wall (inter-row direction wall 21) which is a wall.
Then, the portion along the surface (the upper portion 32A of the fixed side held portion 32) extends along the inner side surface 21N (the surface facing the accommodation space 26) of the terminal holding wall (inter-row direction wall 21) and is fixed. The side-held portion 32 is composed of only the portion along the surface (the upper portion 32A of the fixed side-held portion 32). That is, the fixed-side held portion 32 is composed of only a surface-side portion (upper portion 32A) extending along the inner side surface 21N of the terminal holding wall (inter-row direction wall 21).
Therefore, only the portion near the inner side surface 21N of the terminal holding wall (inter-row direction wall 21) is responsible for holding the fixed side held portion 32. Therefore, the wall thickness (left-right dimension in FIG. 13) of the terminal holding wall (inter-row direction wall 21) can be reduced while maintaining the holding force of the fixed-side held portion 32.

Further, in the present embodiment, the terminal 30 has a horizontal portion 31A configured along the substrate as a fixing object, a horizontal portion 31A, and a surface-side portion (upper portion 32A of the fixed side held portion 32). It has a curved portion 31B to be connected.
Therefore, the horizontal portion 31A and the curved portion 31B of the terminal 30 come into contact with or approach the surface of the substrate, and can be used for soldering to the substrate. That is, the solder fixing portion 31 is formed by the horizontal portion 31A and the curved portion 31B. The curved portion 31B of the terminal 30 is formed in the vicinity of the inner side surface 21N of the terminal holding wall (inter-row direction wall 21) in a plan view (viewed from the direction perpendicular to the substrate), and thus is a storage space. The terminal 30 can be soldered to the substrate up to the vicinity of 26. As a result, the mounting strength of the connector 100 can be improved.

Further, in the present embodiment, as shown in FIG. 13, a part of the horizontal portion 31A (the tip portion in the present embodiment) is formed on the terminal holding wall (inter-row direction wall 21) when viewed from the direction perpendicular to the substrate. On the other hand, it protrudes to the opposite side of the accommodation space 26. Therefore, it is easy to confirm whether or not the connector 100 is properly mounted.

Further, in the present embodiment, as shown in FIG. 13, the intermediate elastic portion 33 includes a first extending portion (first straight portion 33A) extending in a direction away from the substrate as a fixing object (+ Z direction) and a substrate. The second extending portion (second straight portion 33C and second curved portion 33D) extending in the direction approaching (-Z direction), the first extending portion (first straight portion 33A), and the second extending portion (second straight portion 33A). It has a folded-back portion (first curved portion 33B) that connects the two straight portions 33C and the second curved portion 33D).
The first extending portion (first straight portion 33A) and the portion along the surface (upper portion 32A) of the fixed side held portion 32 both extend linearly in the direction perpendicular to the substrate and are linear with each other. Be connected.
For this reason, in the connector 100 where miniaturization is required, where it is necessary to arrange the intermediate elastic portion 33 of the terminal 30 in a limited space, the first extension which is a part of the intermediate elastic portion 33 of the terminal 30 Space above the portion (terminal holding wall, inter-row direction wall 21) that holds the fixed side held portion 32 in the fixed housing 20 for the portion (first straight portion 33A) and the folded portion (first curved portion 33B)). Can be used efficiently for placement.
However, there is no portion where the terminal 30 is bent between the portion along the surface of the fixed side held portion 32 (upper portion 32A) and the folded portion (first curved portion 33B) of the intermediate elastic portion 33. Therefore, when the intermediate elastic portion 33 is elastically deformed, a large load is likely to be applied to the portion along the surface (the upper portion 32A of the fixed side held portion 32) is held. However, in the present embodiment, as described in the above description, since the surface-lined portion (upper portion 32A of the fixed-side held portion 32) has the peeling direction covering surface 37B, the surface-along portion (fixed-side held portion 32). The peeling of the upper portion 32A) of the above is suppressed.

Further, in the present embodiment, the movable side held portion 34 is also held by the movable housings 50 and 60 by insert molding, and includes a portion along the surface (lower portion 34A).
Here, when the portion along the surface (lower portion 34A) of the movable side held portion 34 is adjacent to the intermediate elastic portion 33, the movable side held portion 34 is displaced with respect to the fixed side held portion 32 and is intermediate. When the elastic portion 33 is elastically deformed, a load is applied to the portion of the movable housings 50 and 60 that holds the portion along the surface (the lower portion 34A of the movable side held portion 34), and the movable side held portion 34 There is a concern that the portion along the surface (lower portion 34A) may peel off from the movable housings 50 and 60.
Therefore, in the present embodiment, the portion along the surface (lower portion 34A) of the movable side held portion 34 has the peeling direction covering surface 37B.
Therefore, a force (that is, a force in the peeling direction, a force outward in the inter-row direction in the present embodiment) that peels off the portion along the surface (the lower portion 34A of the movable side held portion 34) is the portion along the surface (movable). When it joins the lower portion 34A) of the side-held portion 34, the peeling direction covering surface 37B along the surface (lower portion 34A of the movable side-held portion 34) acts as a normal force from the movable housings 50 and 60. It receives a force having a component in the direction opposite to the peeling direction. As a result, the portion along the surface (lower portion 34A) of the movable side held portion 34 is suppressed from being separated from the movable housings 50 and 60.

Further, in the present embodiment, the fixed housing 20 and the movable housings 50 and 60 are brought into contact with each other to limit the range of motion of the movable housings 50 and 60 with respect to the fixed housing 20 along the substrate as a fixing object. It has inter-row direction contact surfaces 20X and 50X as "horizontal contact surfaces".
The portion along the surface of the fixed side held portion 32 (upper portion 32A) is exposed to the horizontal contact surface (inter-row direction contact surface 20X) of the fixed housing 20, and the portion along the surface of the movable side held portion 34 (upper portion 32A). The lower portion 34A) is exposed to the horizontal contact surface (inter-row direction contact surface 50X) of the movable housings 50 and 60.
Therefore, the movable housing with respect to the fixed housing 20 up to a position where the surface-aligned portion (upper portion 32A) of the fixed-side held portion 32 and the surface-along portion (lower portion 34A) of the movable-side held portion 34 come into contact with each other. The 50s and 60s can be displaced, and a large range of motion in the direction in which the pair of horizontal contact surfaces (inter-row direction contact surfaces 20X and 50X) face each other can be secured.

<Other effects>
Next, the action and effect of this embodiment will be described from another viewpoint.

In the present embodiment, as shown in FIG. 11, the connector 100 includes a terminal 30 and movable housings 50 and 60 configured to be movable relative to the fixed side members 20 and 40 as “fixed side members”. To be equipped with. The terminal 30 includes a fixed-side held portion 32 held by the fixed-side member, a movable-side held portion 34 held by the movable housings 50 and 60, and a fixed-side held portion 32 and a movable-side held portion 34. It has an elastically deformable intermediate elastic portion 33 located between the two, and a contact portion 36 in contact with the mating connector 10. Therefore, the intermediate elastic portion 33 of the terminal 30 is elastically deformed, so that the movable housings 50 and 60 are allowed to move relative to the fixed side member.
Further, the movable housings 50 and 60 include a first movable housing 50 having a terminal holding portion 51 for holding the movable side held portion 34 of the terminal 30, and a second movable housing 60 integrated with the first movable housing 50. Has.
Therefore, the second movable housing 60 can be formed separately from the first movable housing 50 that holds the terminal 30. Therefore, the degree of freedom in the shape of the second movable housing 60 is improved. As a result, the degree of freedom in designing the movable housings 50 and 60 is improved.
In the above embodiment, the fixed side members 20 and 40 composed of the fixed housing 20 and the reinforcing metal fitting 40 correspond to the "fixed side member", but the "fixed side member" is not limited to this, and the substrate is, for example, a substrate. It may be another terminal.

Further, in the present embodiment, the terminal holding portion 51 of the first movable housing 50 is held by the insert molding with respect to the movable side held portion 34 of the terminal 30. Therefore, when manufacturing the connector 100, the step of press-fitting the terminal 30 into the first movable housing 50 becomes unnecessary.
It should be noted that the ability to form the second movable housing 60 separately from the first movable housing 50 that holds the terminals 30 is particularly advantageous when the movable housings 50 and 60 hold the terminals 30 by insert molding.
This is because when the terminal and the housing are integrally molded by insert molding, the housing must be molded while forming a space for arranging the portion of the terminal that is not held by the housing, so that the housing and the terminal can be freely designed. It is difficult to secure the degree. In particular, when the terminal 30 is integrally molded with the entire movable housing as in the present embodiment, a space is formed to allow displacement of the tip elastic portion 35 and the intermediate elastic portion 33 of the terminal 30 during insert molding. At the same time, since the movable housing must be molded, it is difficult to secure the degree of freedom in designing the movable housing and terminals.
However, according to the present embodiment, since the second movable housing 60 can be molded separately from the first movable housing 50 and the terminal 30, the degree of freedom in designing the second movable housing 60 can be ensured. The degree of freedom in the shape of the movable housing is greatly improved. Therefore, for example, in the connector 100 provided with a plurality of terminals 30, as in the present embodiment, the movable housing 50 has an intervening wall 62 interposed between the intermediate elastic portions 33 and the tip elastic portions 35 of the terminals 30 adjacent to each other in the pitch direction. It becomes easy to form in the second movable housing 60 which is a part of 60. Further, it becomes easy to reduce the gap in the pitch direction between the intervening wall 62 and the terminal 30. As a result, it becomes easy to obtain a connector that is miniaturized in the pitch direction while having an intervening wall 62.
The insert molding is performed by arranging (a part of) the terminals in the molding die and then filling the mold with the molten resin.

Further, in the present embodiment, the second movable housing 60 has an intervening wall 62 as an “intermediate intervening portion” interposed between the intermediate elastic portions 33 of the plurality of terminals 30.
Therefore, for example, contact between the intermediate elastic portions 33 of the plurality of terminals 30 is suppressed.

Further, in the present embodiment, the movable housings 50 and 60 have an inserted portion 66 into which the mating connector 10 is inserted. The opening edge of the inserted portion 66 is formed in the second movable housing 60 as the opening edge pitch extending portion 64.
Therefore, the opening edge of the inserted portion 66 can be formed separately from the first movable housing 50 that holds the terminal 30.

Further, in the present embodiment, as shown in FIG. 13, the first movable housing 50 constitutes the lower portion of the movable housings 50 and 60, and the inserted portion 66 is positioned so as to overlap the first movable housing 50 in the fitting direction. Is formed up to.
That is, in the present embodiment, the mating connector 10 can be inserted to a position where it overlaps with the first movable housing 50 constituting the lower portions of the movable housings 50 and 60 in the fitting direction.
Therefore, the connector 100 can be easily secured with an effective fitting length while reducing the height.

Further, in the present embodiment, as shown in FIG. 13, the terminal 30 has a tip elastic portion 35 for making the contact portion 36 displaceable with respect to the movable housings 50 and 60. Therefore, the contact portion 36 elastically contacts the mating connector 10.
Further, the second movable housing 60 has an inserted portion 66 and a terminal arrangement groove 66X1 as "accommodating portions" for accommodating the contact portion 36 in a displaceable manner. Therefore, the contact portion 36 of the terminal 30 is protected by the second movable housing 60.

Further, in the present embodiment, the movable housings 50 and 60 have an intervening wall 62 as a “tip intervening portion” interposed between the tip elastic portions 35 or the contact portions 36 of the plurality of terminals 30. Therefore, for example, contact between the tip elastic portions 35 and the contact portions 36 of the plurality of terminals 30 is suppressed.

Further, in the present embodiment, the plurality of terminals 30 are arranged between the plurality of first terminals 30A arranged side by side in the pitch direction and the plurality of first terminals arranged side by side in the pitch direction. It is configured to include a plurality of second terminals 30B arranged so as to sandwich the 10.
Further, as shown in FIG. 8, the first movable housing 50 includes a first terminal holding portion 51A that holds a plurality of first terminals 30A, a second terminal holding portion 51B that holds a plurality of second terminals 30B, and the like. It has a connecting portion 52 that connects the first terminal holding portion 51A and the second terminal holding portion 51B.
Therefore, the connecting portion 52 maintains the relative positional relationship between the first terminal holding portion 51A and the second terminal holding portion 51B, so that the first terminal holding portion 51A and the second terminal holding portion 51B are separated from each other. Compared with the above-mentioned embodiment, the first movable housing 50 and the second movable housing 60 can be easily integrated.

Further, in the present embodiment, the first terminal holding portion 51A and the second terminal holding portion 51B are arranged with a space in the inter-row direction. Further, the connecting portion 52 includes a one-sided connecting portion 52A that connects the ends of the first terminal holding portion 51A and the second terminal holding portion 51B on one side in the pitch direction, and the first terminal holding portion 51A and the second terminal holding portion. It has a connecting portion 52B on the other side that connects the ends on the other side in the pitch direction of 51B. Then, the mating connector 10 can be inserted into the space between the first terminal holding portion 51A and the second terminal holding portion 51B.
Therefore, the connector 100 can be easily secured with an effective fitting length while reducing the height. Further, of the first terminal holding portion 51A and the second terminal holding portion 51B, the portion where the one side connecting portion 52A and the other side connecting portion 52B are connected is the pitch of the first terminal holding portion 51A and the second terminal holding portion 51B. Since it is an end portion on one side and the other side in the direction, the space between the first terminal holding portion 51A and the second terminal holding portion 51B (and the space in which the mating connector 10 can be inserted) is in the pitch direction. The dimensions increase.
Further, in the present embodiment, the first movable housing 50 is coupled (welded, bonded, etc.) to the second movable housing 60 at the connecting portion 52 of the first movable housing 50. That is, the connecting portion 52 has a function of connecting with the second movable housing 60 in addition to the function of connecting the pair of terminal holding portions 51. Therefore, it is easier to secure the coupling force as compared with the embodiment in which the terminal holding portion 51 is coupled to the second movable housing 60 only. Further, since the coupling force can be secured, the need to increase the size of the terminal holding portion 51 is reduced.
Further, by coupling with the second movable housing 60 only at the connecting portion 52 of the first movable housing 50 and not at the terminal holding portion 51, the coupling work (welding work, bonding work) can be performed while ensuring the bonding force. You can do it easily.

Further, in the present embodiment, both the one-side connecting portion 52A and the other-side connecting portion 52B are formed with recesses 52Y recessed in the fitting direction for arranging a part of the mating connector 10.
Therefore, the effective fitting length can be lengthened while ensuring the strength of the first movable housing 50.

Further, in the present embodiment, a part of the tip elastic portion 35 is located in the space between the first terminal holding portion 51A and the second terminal holding portion 51B.
Therefore, the tip elastic portion 35 of the terminal 30 can be easily arranged by utilizing the space between the first terminal holding portion 51A and the second terminal holding portion 51B.

Further, in the present embodiment, the first movable housing 50 has a connecting portion 52 as a "first adjacent portion", and the second movable housing 60 has an extension portion 69 as a "second adjacent portion". , The connecting portion 52 and the extending portion 69 are adjacent to each other in a direction orthogonal to the fitting direction. That is, a part of the first movable housing 50 (first adjacent portion) and a part of the second movable housing 60 (second adjacent portion) are adjacent to each other in a direction orthogonal to the fitting direction. Then, the boundary portion X1 (see FIG. 34) between the first adjacent portion and the second adjacent portion faces the fitting direction.
Therefore, it is possible to perform an integration operation (for example, a laser welding operation by irradiating a laser) with respect to the boundary portion X1 exposed in the fitting direction from the fitting direction (lower side).

Further, in the present embodiment, as shown in FIG. 34, the boundary portion X1 between the first adjacent portion (connecting portion 52) and the second adjacent portion (extension portion 69) is fitted in the fitting direction by the fixed side members 20 and 40. Not covered from. This is because the accommodation space 26 (see FIG. 24) is also open downward. Therefore, even when the first movable housing 50 and the fixed housing 20 are already integrated, the integration work of the first movable housing 50 and the second movable housing 60 can be easily performed. Therefore, it is easy to integrate the first movable housing 50 and the second movable housing 60 after molding the fixed housing 20 and the first movable housing 50 using the terminal 30 as an insert product by insert molding.

Further, in the present embodiment, the pair of extension portions 69 (second adjacent portion) makes the protruding portion 59 (first adjacent portion) of the first movable housing 50 from the inter-row direction (direction orthogonal to the fitting direction). Arranged so as to sandwich. Therefore, the first movable housing 50 and the second movable housing 60 can be positioned in the inter-row direction (direction orthogonal to the fitting direction).
Further, an extension portion 69 formed on one side of the second movable housing 60 in the pitch direction (outer wall 61 in the pitch direction in the above example) and a portion of the second movable housing 60 on the other side in the pitch direction (pitch in the above example). The extension portion 69 formed on the outer wall 61) is arranged so as to sandwich the first movable housing 50 from the pitch direction (direction orthogonal to the fitting direction). Therefore, the first movable housing 50 and the second movable housing 60 can be positioned in the pitch direction (direction orthogonal to the fitting direction).

Further, in the present embodiment, of the first movable housing 50 and the second movable housing 60, an extension portion 69 extended toward the first movable housing 50 side (downward in the above modification) to the second movable housing 60. Although the example in which is formed is described, the “extension” of the present disclosure is not limited to this. For example, of the first movable housing 50 and the second movable housing 60, the first movable housing 50 may be formed with an extension portion 69 extending toward the second movable housing 60 side (for example, upward).

<Other effects>
Next, the action and effect of this embodiment will be described from yet another viewpoint.

In the present embodiment, the connector 100 includes fixed side members 20, 40 fixed to the substrate, movable housings 50, 60 configured to be relatively displaceable with respect to the fixed side members 20, 40, and fixed side members 20, A terminal 30 for connecting the 40 and the movable housings 50 and 60 is provided. The range of motion of the movable housings 50 and 60 is defined by the movable housings 50 and 60 abutting on the fixed side members 20 and 40.

Further, the fixed side members 20 and 40 include a fixed housing 20 made of resin and a reinforcing metal fitting 40 integrated with the fixed housing 20. By integrating the fixed housing 20 and the reinforcing metal fitting 40, the strength of the fixed side members 20 and 40 is ensured.
Further, the reinforcing metal fitting 40 and the fixed housing 20 are integrated by insert molding. Therefore, a press-fitting step is not required at the time of manufacturing, as compared with the mode in which the press-fitting is integrated.

Further, in the reinforcing metal fitting 40, one surface (outer surface 40A1 in the pitch direction) is covered with the fixed housing 20, and the other surface (inner surface 40A2 in the pitch direction) is exposed from the fixed housing 20 (“one-sided exposure”). Part 43K ”) is included. Therefore, the portion of the reinforcing metal fitting 40 can contribute to improving the strength of the fixed side members 20 and 40, and the resin can be prevented from being cured while the reinforcing metal fitting 40 is deformed.
That is, since one surface (the outer surface 40A1 in the pitch direction) of the one-sided exposed portion 43K of the reinforcing metal fitting 40 is covered with the fixed housing 20, the portion (the portion (the portion) as compared with the portion where both surfaces are exposed from the resin portion The single-sided exposed portion 43K) can effectively contribute to improving the strength of the fixed housing.
Further, during insert molding, the reinforcing metal fitting 40 can be supported by bringing the mold into contact with the other surface (the inner surface 40A2 in the pitch direction) of the one-sided exposed portion 43K of the reinforcing metal fitting 40. By supporting the reinforcing metal fitting 40, it is possible to prevent the molten resin from pushing the reinforcing metal fitting 40 and deforming the reinforcing metal fitting 40.

Further, in the present embodiment, the fixed side members 20 and 40 have peripheral walls 21 and 22. The peripheral walls 21 and 22 form a storage space 26 in which a movable housing is housed. Then, the other surface (inner surface 40A2 in the pitch direction) of the one-side exposed portion 43K is exposed to the accommodation space 26.
Therefore, as shown in FIG. 26, the other surface (inner surface 40A2 in the pitch direction) of the one-side exposed portion 43K is supported by the mold used to form the accommodation space 26 in which the movable housings 50 and 60 are accommodated. can do. Therefore, the connector 100 can be easily manufactured without complicating the mold.

Further, in the present embodiment, the reinforcing metal fitting 40 is configured to include a flat plate-shaped first flat plate portion 40A. The first flat plate portion 40A constitutes a part of the peripheral walls 21 and 22, and is arranged with the same direction as the wall thickness direction of the peripheral walls 21 and 22 as the plate thickness direction. The single-sided exposed portion 43K is a part of the first flat plate portion 40A.
Therefore, the peripheral walls 21 and 22 of the fixed side members 20 and 40 can be effectively reinforced by the first flat plate portion 40A whose plate thickness direction is the same as the wall thickness direction of the peripheral walls 21 and 22. Further, since insert molding can be performed while supporting the first flat plate portion 40A, deformation of the peripheral walls 21 and 22 in a high temperature environment can be suppressed.

Further, in the present embodiment, the reinforcing metal fitting 40 has a carrier cutting portion 46. The carrier cutting portion 46 refers to a portion formed when a portion connecting the reinforcing metal fitting 40 and the carrier is cut after insert molding. Further, the reinforcing metal fitting 40 has a connecting portion (first curved portion 41A and second flat plate portion 40B) in which a single-sided exposed portion 43K and a carrier cutting portion 46 are connected and at least a part thereof is embedded in the fixed housing 20. Then, the carrier cutting portion 46 is exposed to an external space which is an outer space of the peripheral walls 21 and 22. Therefore, within the limited thickness of the peripheral walls 21 and 22 of the fixed side members 20 and 40, the connecting portion (first curved portion 41A, second flat plate portion 40B) that connects the single-sided exposed portion 43K and the carrier cutting portion 46. ) Can be formed large.

Further, in the present embodiment, the reinforcing metal fitting 40 is a portion in which both sides of one surface (outer surface 40A1 in the pitch direction) and the other surface (inner surface 40A2 in the pitch direction) are exposed from the fixed housing 20. It is configured to include a double-sided exposed portion 43R which is a portion adjacent to the single-sided exposed portion 43K.
Therefore, as shown in FIG. 26, when the fixed housing 20 and the reinforcing metal fitting 40 are insert-molded, the one-sided exposed portion 43K of the reinforcing metal fitting 40 and the other surface (the inner surface 40A2 in the pitch direction) of the double-sided exposed portion 43R are formed. The reinforcing metal fitting 40 can be supported by contacting the mold and also contacting the mold with one surface (the outer surface 40A1 in the pitch direction) of the double-sided exposed portion 43R. By supporting the double-sided exposed portion 43R of the reinforcing metal fitting 40 from both sides, it is possible to more reliably suppress the reinforcing metal fitting 40 from being pushed by the molten resin and deforming the reinforcing metal fitting 40.

Further, in the present embodiment, as shown in FIG. 19, the fixed housing 20 includes an upper portion 20U located above the connector with respect to the reinforcing metal fitting 40. The upper portion 20U is configured to be able to come into contact with the movable housings 50 and 60 that are displaced below the connector. Therefore, even if the movable housings 50 and 60 move downward from the connector, the movable housings 50 and 60 abut on the fixed housing 20 and do not abut on the reinforcing metal fitting 40.
In particular, in the present embodiment, at the upper end of the reinforcing metal fitting 40, the fracture surface of the reinforcing metal fitting 40 (plate end surface 43R3, see FIG. 24) is directed upward, and the fracture surface is formed by the upper portion 20U of the fixed housing 20. And the movable housings 50 and 60 are prevented from coming into contact with each other. Therefore, damage to the movable housings 50 and 60 is suppressed.

Next, the action and effect of this embodiment will be described from another viewpoint.

In the present embodiment, the connector 100 includes fixed side members 20, 40 fixed to the substrate, movable housings 50, 60 configured to be relatively displaceable with respect to the fixed side members 20, 40, and terminals 30. Be prepared. The terminals 30 are the fixed side held portion 32 held by the fixed side members 20 and 40, the movable side held portion 34 held by the movable housings 50 and 60, and the fixed side held portion 32 and the movable side held portion 32. It has an intermediate elastic portion 33 located between the portions 34.
When the movable housings 50 and 60 are displaced relative to the fixed side members 20 and 40, the intermediate elastic portion 33 of the terminal 30 is deformed.

Further, the fixed side held portion 32 of the terminal 30 is held by integrally molding the fixed side members 20 and 40 and the terminal 30. Therefore, the stress remaining on the fixed side members 20 and 40 is suppressed as compared with the mode in which the holding is performed by press fitting.
If stress remains on the fixed side members 20 and 40, the fixed side members 20 and 40 are likely to be deformed when placed in a high temperature environment (particularly during reflow soldering). In particular, in a small connector, the resin wall of the fixed housing becomes thin, so that it is easily deformed greatly.
In the present embodiment, the stress remaining on the fixed side members 20 and 40 is suppressed, so that the connector can be easily miniaturized.

Further, in the present embodiment, the pulling force when pulling out the mating connector 10 is smaller than the maximum elastic force in the elastic range of the intermediate elastic portion 33 of the terminal 30. In connection with this, in the present embodiment, the connector 100 does not have a means for defining the range of motion of the movable housings 50 and 60 in the removal direction (upward of the connector) by abutting on the movable housings 50 and 60. Therefore, a space for providing the means is unnecessary, and the connector 100 can be miniaturized.

As shown in FIG. 36, a convex portion 32N projecting outward in the inter-row direction is formed on the outer surface of the fixed-side held portion 32 in the inter-row direction so as to correspond to the concave portion 32M of the fixed-side held portion 32. Will be done.

One end side surface 32K1 (FIG. 35) of the fixed side convex portion 32K is covered with the fixed housing 20, but the other end side surface 32K2 is not covered with the fixed housing 20.

Further, the terminal 30 is formed with a pair of convex portions (movable side convex portions 34K) projecting outward in the plate width direction (pitch direction). The movable side convex portion 34K is formed in a terminal 30 extending from one end 30K side to the other end 30S side in a part of a section when one end 30K to the other end 30S is regarded as the entire section. By forming the movable side convex portion 34K, the plate width of the terminal 30 is expanded in the formed section. The section in which the movable side convex portion 34K is formed is a section from the start point of the movable side held portion 34 to the middle of the movable side held portion 34. Of the terminals 30, a section in which the movable side convex portion 34K is formed (that is, a section in which the plate width is expanded) is defined as the movable side enlarged width portion 34L.

A recess 34M recessed inward in the inter-row direction is formed on the outer surface of the movable side enlarged width portion 34L in the inter-row direction. A pair of recesses 34M are formed in the central portion in the extending direction and the outer portion in the inter-row direction in the movable side enlarged width portion 34L. Each of the pair of recesses 34M is a substantially rectangular parallelepiped space.

As shown in FIG. 35, of the outer surface of the movable side enlarged width portion 34L in the inter-row direction, the portion where the recess 34M is formed is covered with the first movable housing 50, and the portion where the recess 32M is not formed is covered. , Exposed from the first movable housing 50.

Further, in the above embodiment, the downward range of motion of the movable housings 50 and 60 is defined by the pitch direction overhang portion 67Y of the second movable housing 60 coming into contact with the pitch direction wall 22 of the fixed housing 20. However, the present disclosure is not limited to this. The lower surface of the first movable housing 50 may come into contact with the substrate, so that the downward range of motion of the movable housings 50 and 60 may be defined.

Further, in the above embodiment, the terminal holding portion 51 of the first movable housing 50 is held by the movable side held portion 34 of the terminal 30 by integrally molding the terminal 30 and the first movable housing 50. However, this disclosure is not limited to this. The terminal holding portion 51 of the first movable housing 50 may be held by press fitting with respect to the movable side held portion 34 of the terminal 30. The degree of freedom in designing the movable housing is reduced even when the movable housing is used for holding not only by insert molding but also by press fitting, for example. Therefore, the degree of freedom in designing the movable housing can be improved by forming a part of the movable housing in a second movable housing different from the first movable housing that holds the terminals by press fitting.

Further, in the above embodiment, all the terminals 30 included in the connector 100 are held in the first movable housing 50, and the second movable housing 60 does not hold even one terminal. However, the second movable housing of the present disclosure is not limited to this. For example, the connector may include a plurality of terminals, some of which may be held in the second movable housing. In this case, of the plurality of terminals, the terminal that is not held by the second movable housing but is held by the first movable housing corresponds to the "terminal" of the present disclosure.

Further, in the above embodiment, the terminal 30 as the "terminal" is held by the first movable housing 50, but is not held by the second movable housing 60. Therefore, when forming the second movable housing 60, it is not necessary to consider the function of holding the terminal 30.
However, the "terminal" of the present disclosure is not limited to this. For example, the terminals may be held in the first movable housing as well as in the second movable housing. That is, the second movable housing may play a part of the function of holding the terminals. Even in such a mode, the degree of freedom regarding the shape of the second movable housing is improved as compared with the mode in which the second movable housing bears all the functions of holding the terminals, and as a result, the design of the movable housing is improved. The degree of freedom is improved.

Further, in the present embodiment, an example in which the contact portion 36 of the terminal is formed in a portion different from the movable side held portion 34 has been described, but the contact portion of the present disclosure is a part of the movable side held portion. May be formed as.

Further, in the above embodiment, as shown in FIG. 13, the fixed side held portion 32 and the movable side held portion 34 of the terminal 30 are formed at positions where they overlap in the vertical direction. As a result, the length of the intermediate elastic portion 33 of the terminal 30 was secured. However, this disclosure is not limited to this. For example, the movable side held portion 34 of the terminal 30 may be formed at a position above the fixed side held portion 32 in the vertical direction. Thereby, for example, the lower surface of the first movable housing 50 can be formed at a high position with respect to the substrate, and the contact between the first movable housing 50 and the substrate can be suppressed.

Further, in the above embodiment, an example in which the fixed housing 20 and the first movable housing 50 are molded by one insert molding in the work-in-process manufacturing process has been described. However, the insert molding in the work-in-process manufacturing process of the present disclosure is not limited to this. For example, the insert molding in the work-in-process manufacturing process may be performed in two steps, an insert molding for molding the fixed housing 20 and an insert molding for molding the first movable housing 50.

Further, in the above embodiment, an example in which the movable housings 50 and 60 are composed of the first movable housing 50 and the second movable housing 60 separately formed has been described, but the “movable housing” of the present disclosure is the same. Not limited to. The movable housing of the present disclosure may be integrally molded as a whole.

Further, regarding the structure, shape, etc. of the peeling direction covering surface 37B of the fixed side held portion 32 and the movable side held portion 34, those of the above-described embodiment and the above comparative example have been described, but the "peeling direction covering surface" of the present disclosure has been described. Is not limited to this.
For example, when the terminal 30 is created, the fracture surface (see FIG. 37) formed by punching the material may function as a “peeling direction covering surface”.

Further, in the above embodiment, between the tip elastic portion 35 of the terminal 30 and the lower portion 34A (along the surface) of the movable side held portion 34, the curved portion 34B or the inner portion of the movable side held portion 34. Due to the location of 34C, the tip elastic portion 35 is not "adjacent" to the lower portion 34A (along the plane). Therefore, even if the tip elastic portion 35 is elastically deformed, a large load is not applied to the portion holding the lower portion 34A (the portion along the surface). Therefore, the tip elastic portion 35 of the above embodiment does not correspond to the "elastic portion adjacent to the surface-lined portion" of the present disclosure.
However, the "elastic portion adjacent to the portion along the surface" of the present disclosure is not limited to the intermediate elastic portion 33. The tip elastic portion for relative displacement of the contact portion in contact with the object to be connected may also correspond to the "elastic portion adjacent to the surface-along portion" of the present disclosure as long as it is adjacent to the surface-along portion.
