Description

  The present invention relates to a movable connector, and more particularly to an additional member attached to a housing of a movable connector and a movable connector including the same.

  As a connector that is electrically connected to a connection target, for example, a movable connector as disclosed in Patent Document 1 is known. In this conventional technique, the movable connector includes a fixed housing, a movable housing movable with respect to the fixed housing, and a terminal that is held by the fixed housing and the movable housing and has an elastic portion (movable portion) that is elastically deformable. ing. The movable connector cooperates with each other on the fixed housing side and the movable housing side to form a restricting means for limiting a range of elastic deformation of the elastic portion in the connector fitting direction.

JP-A-2017-212025, FIG. 3 (B)

  However, in such a movable connector, when an external force such as vibration or impact is applied during transportation before starting use, the movable housing vibrates relative to the fixed housing, and the movable portion of the terminal is also elastically deformed. If this vibration is repeated, the movable part may accumulate fatigue and be damaged. Also, the durability of the movable part may be reduced even when the terminal is not damaged before the use of the movable connector. If the durability of the movable part is reduced, the movable part may be damaged at the time of fitting connection with the connection object or after starting use.

  The present invention has been made on the background of the above conventional technology. It is an object of the present invention to prevent a movable connector from being deteriorated or damaged before use.

  In order to achieve the above object, the present invention is configured as having the following features.

  That is, the present invention includes a housing, and a terminal held by the housing, wherein the housing has a first housing and a second movable member movable within a predetermined movable range with respect to the first housing. The movable connector further includes an additional member attached to the housing, and the additional member regulates a relative movement of the second housing with respect to the first housing to be smaller than the movable range. It has a regulation part.

  According to the present invention, since the movable connector includes the additional member having the restricting portion, the movement of the second housing with respect to the first housing is restricted. For this reason, even if external force such as vibration or impact is applied to the movable connector during transportation before starting use, the amplitude of the terminal can be suppressed to a small value. Alternatively, vibration of the terminal can be prevented. Therefore, it is possible to provide a movable connector having terminals that are not easily damaged by fatigue.

  Here, "regulating to be smaller than the movable range" includes the case where the second housing is regulated so as not to be relatively movable with respect to the first housing.

  The restriction portion may be configured to be disposed in a gap between the first housing and the second housing.

  According to the present invention, since the restricting portion is disposed in the gap formed as the movable region of the second housing, the restricting portion itself makes the gap directly small, and thereby the second portion with respect to the first housing. The moving range of the housing can be reliably narrowed. Further, since the regulating portion is arranged in the gap, the space occupied by the regulating portion can be accommodated in the gap, and the size of the movable connector on which the additional member is mounted can be reduced.

  The additional member can be configured to be detachable from the movable connector.

  ADVANTAGE OF THE INVENTION According to this invention, an additional member can be attached to a housing at the time of manufacture of a movable connector. The additional member can be removed from the movable connector after transportation. When the movable connector is mounted on the board or the like, the additional member can be detached from the movable connector, so that the space occupied by the movable connector on the board can be reduced, and other electronic components mounted on the board can be removed. It can be kept out of the way of the parts.

  The restriction portion may be configured to be a first engagement portion that engages with the first housing.

  According to the present invention, the movement of the second housing with respect to the first housing can be restricted by the first engagement portion of the additional member. Therefore, the space occupied by the first engaging portion can be effectively used as the regulating portion. Furthermore, according to the present invention, since the restricting portion engages with the first housing, the additional member can be attached and detached so as not to be caught by the second housing. Therefore, it is possible to prevent the second housing from being displaced in an undesired direction with respect to the first housing, or from being excessively displaced.

  The additional member can be configured to have a first engagement portion that engages with the first housing.

  According to the present invention, since the additional member has the first engagement portion, the additional member can be engaged with the first housing. Therefore, since the additional member is integrated with the first housing, the additional member itself does not vibrate under external force and does not collide with the surrounding movable connector. Furthermore, according to the present invention, since the additional member is engaged with the first housing, the additional member can be attached and detached without being caught by the second housing.

  The restriction portion may be configured to be a second engagement portion that engages with the second housing.

  According to the present invention, the movement of the second housing with respect to the first housing can be restricted by the second engagement portion of the additional member. Therefore, the space occupied by the second engaging portion can be effectively used as the regulating portion. Further, since the additional member is engaged with the second housing, it is easy to prevent the additional member from being enlarged, which can contribute to downsizing of the movable connector to which the additional member is attached.

The additional member may be configured to have a second engagement portion that engages with the second housing.

  According to the present invention, since the additional member has the second engaging portion, the additional member can be engaged with the second housing. Therefore, it is easy to avoid increasing the size of the additional member, for example, by arranging the second engagement portion in a gap formed as a movable region of the second housing. It can contribute to miniaturization.

  ADVANTAGE OF THE INVENTION According to the movable connector of this invention, when receiving external force, such as a vibration and an impact, at the time of the transportation before starting use, it prevents the 2nd housing from vibrating with respect to a 1st housing, and a terminal deform | transforms elastically. Can be prevented. Therefore, according to the movable connector of the present invention, it is possible to prevent the terminal from being deteriorated or damaged before use.

On the other hand, the movable housing 5 has a movable range of a distance d5 toward the right in the X direction between the right surface 52r of the displacement regulating protrusion 52 and the right surface 44r of the displacement regulating receiving portion 44.

Terminal 3

  The plurality of terminals 3 are formed by bending a conductive metal piece, and all have the same shape. Each terminal 3 includes, in order from the base end to the distal end, a board connecting portion 30, a fixed portion 31 for a fixed housing, a movable portion 32, a fixed portion 33 for a movable housing, and a contact portion 34. . When the terminal 3 is attached to the movable connector 1, the plate width is mainly arranged in the X direction and the plate thickness (plate surface) is arranged in the Z direction.

  The terminals 3 are fixed to three places of the substrate, the fixed housing 4 and the movable housing 5, respectively. The board connecting part 30 is a part for electrically connecting the terminal 3 to the board, and is fixed with conductivity by soldering or the like so that the plate surface of the board connecting part 30 contacts the board. The fixed housing fixing portion 31 has a wider plate width than the front and rear portions. The fixed housing fixing portion 31 is a portion for fixing the terminal 3 to the fixed housing 4, and is press-fitted into the groove-shaped terminal fixing portion 45. The movable housing fixing portion 33 has a wider plate width than the front and rear portions. The movable housing fixing portion 33 is a portion for fixing the terminal 3 to the movable housing 5 and is press-fitted into a groove-shaped terminal fixing portion 45.

The contact portions 34 are formed near both upper and lower ends of the terminal 3 and are formed in a mountain (valley) shape that curves in a direction approaching each other. The contact portion 34 is configured to be electrically connected to a connection target inserted into the connection chamber 50 by being pressed and contacted with a predetermined contact pressure so as to be sandwiched from above and below in the Z direction.

Additional member 6

  The movable connector 1 further includes an additional member 6. The additional member 6 is configured as a “cap body” detachable from the housing 2. The additional member 6 has a regulating part 60. The restricting section 60 has a function of restricting the relative movement of the movable housing 5 with respect to the fixed housing 4 so as to be smaller than the movable range.

  Since the movable connector 1 includes the additional member 6 having the restricting portion 60, the movement of the movable housing 5 with respect to the fixed housing 4 is restricted. For this reason, even when external force such as vibration or impact is applied to the movable connector 1 during transportation before the start of use, the amplitude of the terminal 3 can be suppressed small, or vibration of the terminal 3 can be prevented in the first place. . Therefore, it is possible to provide the movable connector 1 including the terminals 3 that are not easily damaged by fatigue. Further, since the vibration of the terminal 3 is suppressed, the movable connector 1 can be stored for a long time. The additional member 6 also has the effect of preventing foreign matter from entering the movable connector 1.

  Here, "regulating to be smaller than the movable range" includes a case where the movable housing 5 is regulated to be immovable relative to the fixed housing 4.

  As shown in FIG. 1, the additional member 6 includes a top plate 61, upper and lower longitudinal restriction pieces 62, 62 in the Z direction, and left and right shorter restriction pieces 63, 63 in the X direction. It has left and right engagement portions 64, 64 as "engagement portions" and left and right protection portions 65, 65.

  The top plate 61 has a function as a base for the additional member 6. The top plate 61 is formed in a rectangular flat plate shape having a long side in the X direction and a short side in the Z direction, and is arranged so that the plate surface is perpendicular to the Y direction. The top plate 61 is formed so that the width (length) in the X direction is longer (wider) than the width of the fixed housing 4. Various portions of the additional member 6 are arranged mainly on the rear surface of the top plate 61 in the Y direction.

  The engagement portion 64 has a function of fixing the additional member 6 to the movable connector 1. As shown in FIG. 3, the engagement portion 64 has a configuration in which a fixing destination of the additional member 6 is the fixed housing 4. The engaging portion 64 extends in a cantilever manner rearward from the top plate 61 along the Y direction. The engaging portion 64 is formed in a flat plate shape having a plate surface along the YZ plane. Thus, the engaging portion 64 is configured to be elastically bent in the X direction at the rear end in the Y direction. That is, the engagement portion 64 is formed as an “elastic engagement piece” having an engagement protrusion (an engagement protrusion 64p described later) at the tip of the elastic arm. The pair of engaging portions 64 on the left and right sides are respectively disposed near both outer sides in the X direction of the top plate 61 corresponding to the width (length) between the side wall portions 42 on the fixed housing 4. ing.

  The engagement portions 64, 64 are provided with engagement protrusions 64p, 64p that protrude closer to each other on the inner plate surface in the X direction. The engagement protrusions 64p, 64p are configured to enter into the engagement grooves 47, 47 to the inclined surfaces 48, 48 of the fixed housing 4 when the additional member 6 is attached to the fixed housing 4, respectively. Since the additional member 6 has such engaging portions 64, 64, the additional member 6 can be engaged with the fixed housing 4. When the additional member 6 is relatively pulled forward with respect to the fixed housing 4 in the Y direction, the engagement protrusions 64p, 64p are caught on the inclined surfaces 48, 48, and the additional member 6 is fixed to the fixed housing 4. It is configured to be difficult to fall out of.

  However, when removing the additional member 6 after the movable connector 1 is mounted on the board, the additional member 6 can be removed by strongly pulling the additional member 6 forward in the Y direction relative to the fixed housing 4. At this time, the additional members 6 can be easily removed from the movable connector 1 with fingers or the like by using the grip portions on both outer sides in the X direction of the protection portions 65 of the top plate 61 in the X direction.

  When the elastic modulus of the engaging portions 64 is large, the removal holes 66 penetrating the top plate 61 in the Y direction may be formed. As shown in FIG. 3, the removal holes 66 are arranged inside the engagement portions 64 in the X direction. When the elasticity of the engaging portions 64 is small, when the additional member 6 is pulled forward with respect to the fixed housing 4 in the Y direction, the rear ends of the engaging portions 64 are deformed in the X direction. And is easily removed. However, when the elastic modulus of the engaging portions 64, 64 is large, the rear ends of the engaging portions 64, 64 are difficult to deform, so that the additional member 6 is difficult to remove from the fixed housing 4. Even in such a case, the additional member 6 can be easily removed from the fixed housing 4 by inserting and removing a removal member such as a flathead screwdriver into the removal holes 66, 66.

  A pair of left and right protection parts 65, 65 are provided on the outside of the engagement parts 64, 64 in the X direction and above and below in the Z direction, respectively. The protection portions 65, 65 may be damaged by the operator's fingers or the like, causing the engagement portions 64, 64 to be damaged, or the additional member 6 attached to the fixed housing 4 to come off. It has a function to prevent The protection portions 65, 65 are each formed in the shape of a rectangular tube around the engagement portions 64, 64, and extend rearward from the top plate 61 along the Y direction to the positions of the rear ends of the engagement portions 64, 64. are doing.

  Each of the protection portions 65, 65 is missing about half of the inner side in the X direction and about half of the rear side in the Y direction, and is formed in an L shape in plan view. The L-shaped configuration of the protection portions 65, 65 corresponds to the corners of the front ends of the side walls 42, 42 of the fixed housing 4. As described above, the protection portions 65 have a function of positioning when the additional member 6 is attached to the fixed housing 4. When the additional member 6 is attached to the fixed housing 4, the engagement portion 64 is prevented from being fitted obliquely so that a large force is applied, particularly in the X direction. Therefore, the protection portions 65 and 65 have a function of preventing the engagement portion 64 from being damaged when the additional member 6 is mounted on the fixed housing 4.

  The long side restriction piece 62 is formed in a rectangular flat plate shape having a long side in the X direction and a short side in the Y direction. The upper and lower longitudinal restriction pieces 62 project from the upper and lower ends in the Z direction near the center of the plate surface of the top plate 61 in the X direction and rearward in the Y direction. The short side restricting piece 63 is formed in a rectangular flat plate shape having a long side in the Z direction and a short side in the Y direction. The left and right short side regulating pieces 63, 63 protrude rearward in the Y direction from the plate surface of the top plate 61 at positions at the left and right ends of the upper and lower longitudinal side regulating pieces 62, 62, respectively.

  The left and right short side restriction pieces 63, 63 are adjacent to the left and right protection portions 65, 65 on both outer sides in the X direction. The protruding (rear) ends of the left and right short side restricting pieces 63, 63 are flush with the lateral rear end surfaces of the left and right protective portions 65, 65, which are missing in an L shape in side view. Then, the protruding ends of the left and right short side regulating pieces 63, 63 and the rear ends of the L-shaped portions of the left and right protection portions 65, 65 each have a π-shaped protruding rear surface 63b in rear view, 63b is formed (see FIG. 1). The protruding rear surfaces 63b, 63b are configured to contact the front surfaces 42f, 42f of the side walls 42, 42 of the fixed housing 4 when the additional member 6 is attached to the fixed housing 4. The additional member 6 is attached to the fixed housing 4 so as not to rattle by being sandwiched between the above-described engaging projections 64p, 64p and the protruding rear surfaces 63b, 63b.

  The upper and lower longitudinal regulation pieces 62, 62 have longitudinal regulation inner surfaces 62i, 62i facing each other, respectively. Further, the left and right short side regulating pieces 63, 63 have short side regulating inner side surfaces 63i, 63i facing each other. The top plate 61 has a regulated inner bottom surface 61i extending in a direction intersecting with the longer regulated inner surfaces 62i, 62i and the shorter regulated inner surfaces 63i, 63i.

  The upper and lower longitudinal regulation pieces 62, 62 and the left and right shorter regulation pieces 63, 63 are formed in a frame shape in rear view. The movable connector 1 has a movable housing with respect to the fixed housing 4 formed by five surfaces of the long side regulating inner side surfaces 62i, 62i, the short side regulating inner side surfaces 63i, 63i, and the regulating inner bottom surface 61i formed inside the frame. 5 is configured to be restricted. That is, the upper and lower longitudinal side restricting pieces 62, the left and right shorter side restricting pieces 63, 63, and the top plate 61 constitute the restricting portion 60. The movable connector 1 is configured such that when the additional member 6 is mounted, the front portion of the movable housing 5 is accommodated in the regulating portion 60. At this time, the upper surface 5t, the lower surface 5u, the side surfaces 5s, 5s, and the front surface 5f of the movable housing 5 are respectively connected to the long side regulating inner side surfaces 62i, 62i, the short side regulating inner side surfaces 63i, 63i, and the regulating inner bottom surface 61i of the additional member 6. Will be opposed.

  When the movable housing 5 is displaced upward in the Z direction, the upper surface 5t comes into contact with the upper longitudinal side regulating inner side surface 62i of the additional member 6 before hitting the lower surface 40u of the top wall portion 40 of the fixed housing 4. On the other hand, when the movable housing 5 is displaced downward in the Z direction, the lower surface 5u comes into contact with the lower longitudinal side inner side surface 62i of the additional member 6 before the lower end of the displacement restricting projection 52 hits the substrate. Further, when the movable housing 5 is displaced forward in the Y direction, before the front surface 52f of the displacement restricting projection 52 contacts the front surface 44f of the displacement restricting receiving portion 44, the front surface 5f hits the restricting inner bottom surface 61i of the additional member 6. .

  Similarly, when the movable housing 5 is displaced to the left in the X direction, before the left surface 521 of the displacement restricting projection 52 hits the left surface 441 of the displacement restricting receiving portion 44, the side surface 5s is positioned on the left side of the additional member 6 on the short side. The inner surface 63i will be hit. On the other hand, when the movable housing 5 is displaced rightward in the X direction, before the right surface 52r of the displacement restricting projection 52 hits the right surface 44r of the displacement restricting receiving portion 44, the side surface 5s is positioned on the right side of the additional member 6 on the short side. The inner surface 63i will be hit.

  In the regulating portion 60, the upper and lower longitudinal side regulating pieces 62, 62 are arranged in a gap (movable gap) between the fixed housing 4 and the movable housing 5. As described above, since the restricting portion 60 is disposed in the gap formed as the movable region of the movable housing 5, the restricting portion 60 reduces the gap, thereby ensuring the movable range of the movable housing 5 with respect to the fixed housing 4. Can be narrowed down to Further, since the regulating portion 60 is arranged in the gap, the space occupied by the regulating portion 60 can be accommodated in the gap, and the movable connector 1 on which the additional member 6 is mounted can be reduced in size.

  The long side regulating pieces 62, 62 are configured to have extended portions 62e, 62e so as to project, for example, twice as long as the short side regulating pieces 63, 63. That is, the long side regulating inner side surfaces 62i, 62i have an area twice as large as the short side regulating inner side surfaces 63i, 63i by having the extension portions 62e, 62e, respectively. The long-side restricted inner side surfaces 62i, 62i receive a large area of the impact received by the additional member 6 when the movable housing 5 is displaced, and prevent the movable connector 1 particularly the movable housing 5 from being damaged. Is configured.

  In the right angle type movable connector 1 as in the present embodiment, there is a possibility that the movable portion 32 is plastically deformed by the weight of the movable housing 5 and the terminal 3 during transportation. However, since the long-side restricting pieces 62, 62 are configured to have the extended portions 62e, 62e extending longer in the rear in the Y direction, it is possible to effectively prevent the movable portion 32 from being plastically deformed. it can.

  As shown in FIG. 2, the movable housing 5 has a movable range of a distance d6 upward in the Z direction between the upper surface 5t and the upper longitudinal inner side surface 62i of the additional member 6. . On the other hand, the movable housing 5 has a movable range of a distance d7 downward in the Z direction between the lower surface 5u and the lower longitudinal inner side surface 62i on the lower side of the additional member 6. FIG. 2 shows an example in which the distance d6 is smaller than the distance d1 and the distance d7 is smaller than the distance d2. However, the movable connector 1 is configured such that at least the sum of the distance d6 and the distance d7 is smaller than the sum of the distance d1 and the distance d2. That is, the additional member 6 regulates the relative movement of the movable housing 5 in the vertical direction in the Z direction with respect to the fixed housing 4 so as to be smaller than a predetermined movable range.

  Further, as shown in FIG. 2, the movable housing 5 has a movable range of a distance d8 forward in the Y direction between the front surface 5f and the regulated inner bottom surface 61i of the additional member 6. The movable connector 1 is configured such that the distance d8 is smaller than the distance d3. That is, the additional member 6 regulates the relative movement of the movable housing 5 in the forward direction in the Y direction with respect to the fixed housing 4 so as to be smaller than a predetermined movable range.

  Similarly, as shown in FIG. 3, the movable housing 5 has a movable range of a distance d9 toward the left in the X direction between the side surface 5s and the left-side restricted inner side surface 63i of the additional member 6. have. On the other hand, the movable housing 5 has a movable range of a distance d10 toward the right in the X direction between the side surface 5s and the right-hand side restricted inner side surface 63i of the additional member 6. FIG. 3 shows an example in which the distance d9 is smaller than the distance d4 and the distance d10 is smaller than the distance d5. However, the movable connector 1 is configured such that at least the sum of the distance d9 and the distance d10 is smaller than the sum of the distance d4 and the distance d5. That is, the additional member 6 regulates the relative movement of the movable housing 5 relative to the fixed housing 4 in the left-right direction in the X direction so as to be smaller than a predetermined movable range.

  The additional member 6 here is formed separately from the fixed housing 4 and the movable housing 5 of the movable connector 1. In other words, the additional member 6 is configured to be detachable from the movable connector 1. Thereby, the additional member 6 can be attached to the housing 2, here the fixed housing 4 at the time of manufacturing the movable connector 1, and the additional member 6 can be removed from the movable connector 1 after transportation. When the movable connector 1 is mounted on a substrate or the like, the additional member 6 can be removed from the movable connector 1. Therefore, the occupied space around the movable connector 1 on the board can be reduced, and it can be prevented that other electronic components mounted on the board are obstructed.

  On the other hand, the additional member 6 may be attached to the fixed housing 4 or the movable housing 5 of the movable connector 1 by a hinge or the like, and may not be removable. Thereby, the trouble of disposing of the removed additional member 6 can be saved.

  When the additional member 6 is removed from the movable connector 1, it is preferable that the connection with the movable housing 5 is first released and then the additional member 6 is removed from the fixed housing 4. As a result, when the additional member 6 is detached from the movable connector 1, the movable housing 5 is hooked and a force is applied, and the movable portion 32 of the terminal 3 is deformed in an undesired direction or excessively deformed. Is prevented.

  In the present embodiment, in a configuration in which the fixing destination of the additional member 6 is the fixed housing 4, the engaging portions 64, 64 as “first engaging portions” are provided in the gap between the fixed housing 4 and the movable housing 5. An example of not being placed is shown. However, the engaging portions 64, 64 may be arranged in a gap (movable gap) between the fixed housing 4 and the movable housing 5. This can be realized, for example, by forming a configuration corresponding to the engagement grooves 47, 47 and the inclined surfaces 48, 48 of the fixed housing 4 on the inner surface side of the fixed housing 4.

  That is, the restricting portion 60 is constituted by the “first engaging portion” that engages with the fixed housing 4. According to this configuration, the movement of the movable housing 5 with respect to the fixed housing 4 can be restricted by the “first engagement portion” of the additional member 6. Therefore, the space occupied by the “first engagement portion” can be effectively used as the restriction portion 60. Further, according to this configuration, since the restricting portion 60 is engaged with the fixed housing 4, the attachment and detachment of the additional member 6 can be performed without being caught by the movable housing 5. Therefore, it is possible to prevent the movable housing 5 from being displaced in an undesired direction with respect to the fixed housing 4 and from being excessively displaced.

Second embodiment (FIGS. 4 to 6)

  Hereinafter, a movable connector 101 as a second embodiment of the “movable connector” of the present invention will be described mainly with reference to the drawings, mainly with respect to a portion different in configuration from the above-described movable connector 1. That is, the movable connector 101 can exhibit the same effects as those of the above-described movable connector 1 unless otherwise specified.

Movable connector 101

  The movable connector 101 of the present embodiment includes a housing 102 and terminals 3 held by the housing 102. As shown in FIGS. 5 and 6, the movable connector 101 has, as the housing 102, a fixed housing 104 as a “first housing” and a movable housing 105 as a “second housing”. I have. The terminal 3 is the same for the movable connector 1 and the movable connector 101.

Fixed housing 104

  As shown in FIG. 6, the fixed housing 104 has a pair of side walls 142, 142 located on the left and right sides in the X direction. The side walls 142, 142 are different from the side walls 42, 42 of the first embodiment in that the engagement grooves 47, 47 and the inclined surfaces 48, 48 are not formed on the outer surfaces. Other than this, the fixed housing 104 is configured similarly to the fixed housing 4.

Movable housing 105

  As shown in FIG. 5, the movable housing 105 has an upper surface 105t and a lower surface 105u. In the upper surface 105t and the lower surface 105u, at the center in the X direction, a pair of engagement grooves 157 and 157 recessed inward in the Z direction extend from the rear ends of the upper surface 105t and the lower surface 105u along the Y direction. Is formed. On the front side of the upper surface 105t and the lower surface 105u, a pair of inclined surfaces 158 and 158 that are inclined from the upper surface 105t and the lower surface 105u toward the engagement grooves 157 and 157, respectively, are formed. In this manner, the upper surface 105t and the lower surface 105u are different from the upper surface 5t and the lower surface 5u of the first embodiment in that the engagement grooves 157 and 157 and the inclined surfaces 158 and 158 are formed respectively. Other than this, the movable housing 105 is configured similarly to the movable housing 5.

  The movable housing 105 is configured to be relatively movable with respect to the fixed housing 104 within a predetermined movable range. That is, as shown in FIG. 6, the movable housing 105 is movable between the side surface 105s of the movable housing 105 and the inner side surface 142i of the side wall portion 142 of the fixed housing 104 by a distance d11 toward the left in the X direction. Have a range. On the other hand, the movable housing 105 has a movable range of a distance d12 toward the right in the X direction between the side surface 105s and the inner side surface 142i of the side wall portion 142.

Additional member 106

  The movable connector 101 further includes an additional member 106. The additional member 106 is also configured as a “cap body” detachable from the housing 102. The additional member 106 has a regulating part 160. Similarly to the restricting portion 60, the restricting portion 160 also has a function of restricting the relative movement of the movable housing 105 with respect to the fixed housing 104 so as to be smaller than the movable range.

  As shown in FIG. 4, the additional member 106 includes a top plate 61, upper and lower longitudinal side restriction pieces 162 and 162 in the Z direction, left and right shorter side restriction pieces 63 and 63 in the X direction, and a “second And upper and lower engaging portions 164 and 164 as "engaging portions". The additional member 106 does not have a configuration corresponding to the left and right protection portions 65.

  The top plate 61 is formed to have a width (length) in the X direction shorter (narrower) than the width of the fixed housing 104. The top plate 61 of the movable connector 101 only needs to be at least wider than the movable housing 105 and does not depend on the width of the fixed housing 104. Therefore, in the second embodiment, the amount of material used for the top plate 61 can be reduced, and costs can be suppressed.

  As shown in FIG. 5, the engagement portion 164 in the second embodiment has a configuration in which the movable member 105 is fixed to the additional member 106. The engagement portion 164 extends rearward from the top plate 61 along the Y direction in a cantilever shape. The engaging portion 164 is formed in a flat plate shape having a plate surface along the XY plane. Thus, the engaging portion 164 is configured to be elastically bent in the Z direction at the rear end in the Y direction. That is, the engagement portion 164 is formed as an “elastic engagement piece” having an engagement protrusion (an engagement protrusion 164p described later) at the tip of the elastic arm. The pair of upper and lower engaging portions 164 and 164 are located above and below the top plate 61 in the Z direction near the center in the X direction corresponding to the height between the upper surface 105t and the lower surface 105u of the movable housing 105. It is arranged near each side.

  The engagement portions 164, 164 are provided with engagement protrusions 164p, 164p that protrude closer to each other on the inner plate surface in the Z direction. The engagement protrusions 164p and 164p are configured to enter the engagement grooves 157 and 157 through the inclined surfaces 158 and 158 of the movable housing 105 when the additional member 106 is attached to the movable housing 105, respectively. Since the additional member 106 has such engaging portions 164 and 164, the additional member 106 can be engaged with the movable housing 105. When the additional member 106 is relatively pulled forward with respect to the movable housing 105 in the Y direction, the engagement protrusions 164p and 164p are caught on the inclined surfaces 158 and 158, and the additional member 106 is moved by the movable housing 105. It is configured to be difficult to fall out of.

  However, when the additional member 106 is removed after the movable connector 101 is mounted on the board, the additional member 106 can be removed by being strongly pulled forward in the Y direction relative to the movable housing 105. .

  The additional member 106 may be provided with holes 166 and 166 that penetrate the top plate 61 in the Y direction. As shown in FIG. 5, the removal holes 166 and 166 are arranged inside the engagement portions 164 and 164 in the Z direction.

  As shown in FIG. 4, the long-side restricting piece 162 is formed in a rectangular flat plate shape having a long side in the X direction and a short side in the Y direction, similarly to the long-side restricting piece 62. The upper and lower longitudinal restriction pieces 162 protrude rearward in the Y direction from the upper and lower ends in the Z direction near the center of the plate surface of the top plate 61 in the X direction. The upper and lower longitudinal regulation pieces 162, 162 and the left and right shorter regulation pieces 63, 63 are formed in a frame shape in rear view. Like the long-side restriction piece 62, the long-side restriction piece 162 has an extended portion 62e that projects rearward in the Y direction from the left and right short-side restriction pieces 63, 63.

  The upper and lower longitudinal side restriction pieces 162, 162 have engagement escape portions 162c, 162c, which are respectively formed in a groove shape toward the lower side and the upper side in the Z direction, on the opposing surface side near the center in the X direction. . The above-described engagement portions 164 and 164 are arranged corresponding to the engagement escape portions 162c and 162c, respectively. As a result, the engaging portions 164 and 164 are located inside the frame shape of the upper and lower longitudinal side restriction pieces 162 and 162 and the left and right shorter side restriction pieces 63 and 63.

  The engagement escape portion 162c has a function similar to that of the protection portion 65 of the first embodiment.

  Thus, when the additional member 106 is mounted, the movable connector 101 houses the front portion of the movable housing 105 on the inner peripheral side of the frame formed by the upper and lower longitudinal regulation pieces 162, 162 and the left and right shorter regulation pieces 63, 63. It is configured to be. At this time, the engagement protrusions 164p and 164p of the additional member 106 are in an engagement state sandwiching the engagement grooves 157 and 157 to the inclined surfaces 158 and 158 of the movable housing 105, respectively. Therefore, the additional member 106 is configured to be integrated with the movable housing 105 by being attached to the movable connector 101. At this time, the upper and lower longitudinal regulation pieces 162, 162 and the left and right shorter regulation pieces 63, 63 are arranged in a gap (movable gap) between the fixed housing 104 and the movable housing 105.

  Further, in the movable connector 101, as shown in FIG. 5, the engagement portions 164 and 164 are also arranged in a gap (movable gap) between the fixed housing 104 and the movable housing 105. As described above, since the engaging portions 164 and 164 are arranged in the gap formed as the movable area of the movable housing 105, the engaging portions 164 and 164 themselves directly reduce the gap. Thus, the range of relative movement of the movable housing 105 with respect to the fixed housing 104 can be reliably reduced. Further, since the engaging portions 164 and 164 are arranged in the gap, the space occupied by the engaging portions 164 and 164 can be accommodated in the gap, and the size of the movable connector 101 to which the additional member 106 is mounted can be reduced. .

  On the outer peripheral side of the frame formed by the long side regulating pieces 162, 162 and the left and right short side regulating pieces 63, 63, there are long side regulating outer surfaces 162o, 162o and short side regulating outer surfaces 63o, 63o, respectively. Is formed. The movable connector 101 is configured such that the displacement of the movable housing 105 with respect to the fixed housing 104 is restricted by four surfaces, namely, the long side outer side surfaces 162o, 162o and the short side outer side surfaces 63o, 63o. Then, the upper long side restricted outer surface 162o and the left and right short side restricted outer surfaces 63o, 63o of the integrated additional member 106 are respectively connected to the lower surface 40u of the ceiling wall portion 40 and the left and right side wall portions 142 of the fixed housing 104. It faces the inner side surfaces 142i and 142i. Further, the lower longitudinal side outer surface 162o of the additional member 106 is opposed to the substrate.

  As shown in FIG. 5, when the integrated movable housing 105 is displaced upward in the Z direction, the movable housing 105 is displaced upward with respect to the lower surface 40 u of the fixed housing 104 with a shorter displacement than the upper surface 105 t hits. The side regulating outer surface 162o comes into contact. Similarly, as shown in FIG. 6, when the movable housing 105 is displaced to the left in the X direction, the movable housing 105 is moved to the left inner side surface 142i of the fixed housing 104 before the left side surface 105s hits. 63o will be hit. On the other hand, when the movable housing 105 is displaced rightward in the X direction, the right short side restricted outer surface 63o hits the right inner side surface 142i before the right side surface 105s hits.

  As shown in FIG. 5, the movable housing 105 extends a movable range of a distance d13 upward in the Z direction between the upper longitudinal side outer surface 162o of the additional member 106 and the lower surface 40u of the fixed housing 104. Have. The distance d13 is smaller than the distance d1 that is the upward movable range in the Z direction when the movable connector 101 does not attach the additional member 106. On the other hand, the movable housing 105 has a movable range of a distance d2 downward in the Z direction between the lower end of the displacement restricting projection 52 and the lower end of the fixed leg 46 of the fixed housing 104. This is constant regardless of the presence or absence of the additional member 106. Therefore, the additional member 106 regulates the relative movement of the movable housing 105 in the vertical direction in the Z direction with respect to the fixed housing 104 so as to be smaller than a predetermined movable range.

  Here, if the movable housing 105 does not have the displacement regulating protrusion 52 as shown in FIG. 5, the movable housing 105 is disposed between the lower longitudinal side outer surface 162 o of the additional member 106 and the substrate. Has a movable range of a distance d14 downward in the Z direction. On the other hand, a configuration may be adopted in which the lower longitudinal side restricting piece 162 of the additional member 106 extends below the bottom wall 41 of the fixed housing 104. With this configuration, the movable connector 101 can further narrow the movable range of the movable housing 105 with respect to the fixed housing 104 downward in the Z direction.

  Similarly, as shown in FIG. 6, the movable housing 105 is disposed between the left side short-side restricted outer surface 63o of the additional member 106 and the inner side surface 142i of the left side wall 142 of the fixed housing 104 in the X direction. Has a movable range of a distance d15 toward the left. On the other hand, the movable housing 105 has a distance toward the right in the X direction between the right short side regulating outer surface 63o of the additional member 106 and the inner side surface 142i of the right side wall 142 of the fixed housing 104. It has a movable range of d16. FIG. 6 shows an example in which the distance d15 is smaller than the distance d11 and the distance d16 is smaller than the distance d12.

  However, the movable connector 101 is configured such that at least the sum of the distance d15 and the distance d16 is smaller than the sum of the distance d11 and the distance d12. That is, the additional member 106 regulates the relative movement of the movable housing 105 relative to the fixed housing 104 in the X direction in the left-right direction so as to be smaller than a predetermined movable range.

  When the movable housing 105 is displaced rearward in the Y direction with respect to the fixed housing 104, the additional member 106 does not have to contact the fixed housing 104. However, the surface of the additional member 106 that contacts the fixed housing 104 (corresponding to the protruding rear surface 63b of the first embodiment (see FIGS. 1 and 3)) may be configured to extend rearward in the Y direction (FIG. 11). The length corresponding to the distance d20 is shortened.) In this way, when the movable housing 105 is displaced rearward in the Y direction, the additional member 106 comes into contact with the fixed housing 104 before the displacement regulation protrusion 52 comes into contact with the displacement regulation receiving portion 44. That is, the additional member 106 regulates the relative movement of the movable housing 105 in the rear direction in the Y direction with respect to the fixed housing 104 so as to be smaller than a predetermined movable range.

Since the movable connector 201 is a straight type, although the fixed housing 204 has a different orientation from the fixed housing 4, the structures are similar to each other, and the front wall portion 240 and the rear wall portion 241 are connected to the top of the fixed housing 4. It corresponds to the wall 40 and the bottom wall 41.

  The rear wall portion 241 is different from the bottom wall portion 41 in that there is no portion missing vertically in the Z direction. Further, as shown in FIGS. 8 and 9, a pair of displacement restriction members, each of which has a rectangular column shape and is downwardly downward in the Z direction, are formed on the inner surfaces of the side wall portions 242 and 242, except for the front ends of the side wall portions 242 and 242. Receiving parts 244 and 244 are formed. The displacement regulation receiving portion 244 has a different extension direction from the displacement regulation receiving portion 44 of the fixed housing 4. The pair of fixed leg portions 246, 246 differ from the fixed leg portions 46, 46 in that they project downward in the Z direction along the Z direction in which the front wall 240 extends. Except for the above points, the fixed housing 204 is configured similarly to the fixed housing 4.

Movable housing 205

  Like the fixed housing 204, the movable housing 205 has a different orientation from the movable housing 5, but has a similar structure. The movable housing 205 is different from the movable housing 5 in that the movable housing 205 has displacement regulating protrusions 252 instead of the displacement regulating protrusions 52. As shown in FIGS. 8 and 9, the pair of displacement restricting projections 252 protrude downward in the Z direction from the rear end of the movable housing 205 and both outer sides in the X direction. The displacement restricting projection 252 has a function of restricting excessive displacement of the movable housing 205 by contacting the displacement restricting receiving portions 244 and 244 in the X direction and the Y direction and contacting the substrate in the downward direction in the Z direction. ing.

  As shown in FIG. 8, the movable housing 205 has a movable range of a distance d17 toward the front in the Y direction between the front surface 252f of the displacement regulation protrusion 252 and the front surface 244f of the displacement regulation receiving portion 244. I have. On the other hand, the movable housing 205 has a movable range of a distance d18 toward the rear in the Y direction between the rear surface 252b of the displacement restricting projection 252 and the rear surface 244b of the displacement restricting receiving portion 244. Further, the movable housing 205 has a movable range of a distance d2 downward in the Z direction between the lower end of the displacement regulation protrusion 252 and the lower end of the fixed leg 246 of the fixed housing 204. On the other hand, as shown in FIG. 9, the movable housing 205 moves the movable range of the distance d3 upward in the Z direction between the upper surface 252t of the displacement restricting protrusion 252 and the upper surface 244t of the displacement restricting receiving portion 244. Have.

  Then, as shown in FIG. 9, the movable housing 205 moves the movable range of the distance d4 toward the left in the X direction between the left surface 252l of the displacement regulating protrusion 252 and the left surface 244l of the displacement regulating receiving portion 244. Have. On the other hand, the movable housing 205 has a movable range of a distance d5 toward the right in the X direction between the right surface 252r of the displacement control protrusion 252 and the right surface 244r of the displacement control receiving portion 244.

Terminal 203

  The terminal 203 is configured in the same manner as the terminal 3 except that the orientation of the board connection part 230 is different from that of the board connection part 30.

Additional member 206

  The movable connector 201 further includes an additional member 206. The additional member 206 is also configured as a “cap body” detachable from the housing 202. The additional member 206 has a regulating part 260. Like the restricting portion 60, the restricting portion 260 also has a function of restricting the relative movement of the movable housing 205 with respect to the fixed housing 204 so as to be smaller than the movable range.

  As shown in FIG. 7, the additional member 206 includes a top plate 61, front and rear long side restriction pieces 262 and 262 in the Y direction, left and right short side restriction pieces 63 and 63 in the X direction, and a “first It has left and right engagement portions 64, 64 as "engagement portions" and left and right protection portions 265, 265.

As described above, in particular, in the straight type movable connector 201 in which the movable portion 32 is not easily plastically deformed by the weight of the movable housing 205 and the terminal 203, the longitudinal side restricting pieces 262 and 262 do not have the extended portions 62e and 62e. You can also.

  As shown in FIG. 8, the movable housing 205 has a movable range of a distance d6 toward the front in the Y direction between the front surface 205f and the front longitudinal inner side surface 262i of the additional member 206. . On the other hand, the movable housing 205 has a movable range of a distance d7 toward the rear in the Y direction between the rear surface 205b and the rear longitudinal inner side surface 262i of the additional member 206. FIG. 8 shows an example in which the distance d6 is smaller than the distance d17 and the distance d7 is smaller than the distance d18. However, the movable connector 201 is configured such that at least the sum of the distance d6 and the distance d7 is smaller than the sum of the distance d17 and the distance d18. That is, the additional member 206 regulates the relative movement of the movable housing 205 in the front-rear direction in the Y direction with respect to the fixed housing 204 so as to be smaller than a predetermined movable range.

  Further, as shown in FIGS. 8 and 9, the movable housing 205 has a movable range of a distance d8 upward in the Z direction between the upper surface 205t and the regulated inner bottom surface 61i of the additional member 206. I have. The movable connector 201 is configured such that the distance d8 is smaller than the distance d3, as shown in FIG. That is, the additional member 206 regulates the upward relative movement of the movable housing 205 with respect to the fixed housing 204 in the Z direction so as to be smaller than a predetermined movable range.

  On the other hand, the movable range of the distance d2 between the lower end of the displacement regulating protrusion 252 and the lower end of the fixed leg 246 of the fixed housing 204, that is, the downward direction d2 in the Z direction is related to the presence or absence of the additional member 206. Is constant. Therefore, the additional member 206 regulates the relative movement of the movable housing 205 in the vertical direction in the Z direction with respect to the fixed housing 204 so as to be smaller than a predetermined movable range.

  Similarly, as shown in FIG. 9, the movable housing 205 has a movable range of a distance d9 toward the left in the X direction between the side surface 205 s and the left-hand side restricted inner side surface 63 i of the additional member 206. have. On the other hand, the movable housing 205 has a movable range of a distance d10 to the right in the X direction between the side surface 205s and the right-hand side restricted inner side surface 63i of the additional member 206. FIG. 9 shows an example in which the distance d9 is smaller than the distance d4 and the distance d10 is smaller than the distance d5. However, the movable connector 201 is configured such that at least the sum of the distance d9 and the distance d10 is smaller than the sum of the distance d4 and the distance d5. That is, the additional member 206 regulates the relative movement of the movable housing 205 in the X direction with respect to the fixed housing 204 in the X direction so as to be smaller than a predetermined movable range.

  In the additional member 206, the longitudinal regulation pieces 262 and 262 and the left and right short regulation pieces 63 and 63 constituting the regulation section 260 are not arranged in the gap between the fixed housing 204 and the movable housing 205. However, also in the movable connector 201, the additional member 206 regulates the relative movement of the movable housing 205 with respect to the fixed housing 204 so as to be smaller than a predetermined movable range. Therefore, the movable connector 201 can be configured so that the restricting portion 260 is not disposed in the gap (movable gap) between the fixed housing 204 and the movable housing 205.

  In a configuration in which the restricting portion 260 does not enter the gap between the fixed housing 204 and the movable housing 205, positioning of the additional member 206 on the movable connector 201 is particularly difficult in the front and rear directions in the Y direction. Therefore, as shown in FIG. 7, the left and right protection portions 265 and 265 may be formed with protruding rear surfaces 265 b and 265 b that protrude downward in the Z direction from the short-side regulating pieces 63 and 63. Correspondingly, the fixing housing 204 may have a recess for positioning.

Except for this, the fixed housing 404 is configured similarly to the fixed housing 204.

Additional member 406

  The movable connector 401 further includes an additional member 406. The additional member 406 is also configured as a “cap body” detachable from the housing 402. The additional member 406 has a regulating portion 460. Like the restricting portion 60, the restricting portion 460 also has a function of restricting the relative movement of the movable housing 305 with respect to the fixed housing 404 so as to be smaller than the movable range. In particular, the restricting portion 460 has a function of restricting the movable housing 305 with respect to the fixed housing 404 so as not to be relatively movable.

  As shown in FIG. 13, the additional member 406 includes a top plate 61, front and rear long side restriction pieces 262 and 262 in the Y direction, and left and right short side restriction pieces 63 and 63 in the X direction.
