Description

[Technical Field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] A connector such as that described in Patent Document 1 is known. This connector includes a movable housing that is displaceable relative to an attachment object, and terminals that electrically connect the attachment object and a connection object. The terminals have a displacement portion formed with a contact portion that contacts the connection object. The displacement portion is fixed to the movable housing, and is configured to displace integrally with the movable housing. In such a connector, when connecting to an object to be connected, the movable housing and the displacement portion can be displaced in accordance with the positional deviation of the object to be connected.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-98160 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the above-described connector is used in a vibration environment, such as in an automobile, the movable housing and the displacement part are displaced by inertial force, causing the contact part formed on the displacement part to repeatedly slide against the connection object, or even if the contact part does not slide, the elastically deformable intermediate deformation part connected to the displacement part may repeatedly elastically deform. Such repeated sliding and elastic deformation may cause wear of the contact part or breakage of the intermediate deformation part. In particular, if the frequency of vibrations from an automobile engine or road vibrations matches the resonant frequency of the displacement part of a connector when connected to an object, the displacement part will vibrate violently together with the object, increasing the risk of wear and tear as described above. For this reason, in recent years, there has been a demand to increase the resonant frequency of the displacement part of a connector when connected to an object, so that the frequency (natural frequency) of the connector's displacement part does not match the frequency of vibrations from an automobile engine or road vibrations.

[0005] However, in the connector described above, the displacement portion of the terminal is fixed to the movable housing, so when the displacement portion is displaced, the movable housing also displaces integrally with the displacement portion. Therefore, the mass of the portion that displaces integrally with the displacement portion is large. This tends to increase the inertial force acting on the integrally displaced portion and lower the resonant frequency. As a result, the above demands could not be fully met.

[0006] An object of the present disclosure is to provide a connector having a movable housing that can suppress repeated sliding between a contact portion and a connection object. [Means for solving the problem]

[0007] In this disclosure, when describing the structure and shape of an object, the X direction, Y direction, and Z direction are used, which are directional concepts relative to the object and perpendicular to each other.

[0008] The connector according to the first aspect is a connector that can be attached to an attachment object, and includes a movable housing that can be displaced relative to the attachment object in an X direction, which is a direction perpendicular to the connection direction of the connection object to the connector, and a terminal that electrically connects the attachment object and the connection object, wherein the terminal has a contact portion that comes into contact with the connection object and a displacement portion that can be displaced in the X direction relative to the attachment object, and the displacement portion is displaceable relative to the movable housing.

[0009] In the above aspect, the connector includes a movable housing that is displaceable in the X direction, which is a direction perpendicular to the connection direction, relative to the attachment object, and a terminal that electrically connects the attachment object and the connection object. The terminal has a displacement portion that is displaceable in the X direction relative to the attachment object. The displacement portion is formed with a contact portion that comes into contact with the connection object. In this way, since both the movable housing and the displacement portion can be displaced in the X direction relative to the attachment object, when connecting the connector to the connection object, the movable housing and the displacement portion can be displaced to match the positional deviation of the connection object in the X direction.

[0010] Furthermore, in the above aspect, the displacement portion is displaceable relative to the movable housing. Therefore, unlike the prior art (wherein, when the displacement portion is displaced, the movable housing is displaced integrally with the displacement portion), the mass of the portion that displaces integrally with the displacement portion when the displacement portion is displaced is small, and as a result, repeated sliding between the contact portion and the connection object (including repeated elastic deformation of the intermediate deformation portion if the terminal has such a portion) can be suppressed.

[0011] In the connector of the second aspect, in the first aspect, the movable housing has a movable side limiting portion, and the movable side limiting portion is configured so that when the movable housing is displaced in the X direction, the movable side limiting portion abuts against the displacement portion, thereby limiting the position of the displacement portion in the X direction relative to the movable housing within a predetermined range.

[0012] Since the displacement portion is displaceable relative to the movable housing, when the movable housing is displaced relative to the attachment object, the displacement portion is displaced relative to the movable housing. In the above aspect, the movable housing has a movable-side limiting portion that is configured to abut against the displacement portion when the movable housing is displaced in the X direction, thereby limiting the position of the displacement portion in the X direction relative to the movable housing within a predetermined range. Therefore, for example, by displacing the movable housing in accordance with the positional misalignment of the connection object in the X direction prior to contact between the connection object and the terminal, the displacement section can be displaced in advance in accordance with the positional misalignment of the connection object in the X direction before the connection object and the terminal are brought into contact. As a result, the distance of the positional misalignment that can be accommodated can be made longer compared to an embodiment in which the positional misalignment of the connection object is accommodated only by the terminal structure.

[0013] A third aspect of the connector is the first or second aspect, wherein the movable housing cannot be displaced in a Y direction, which is a direction perpendicular to both the connecting direction and the X direction, relative to the attachment object.

[0014] In the above embodiment, the movable housing cannot be displaced in the Y direction relative to the attachment object. Therefore, there is no need to provide a structure for displacing the movable housing in the Y direction, and as a result, for example, the connector can be made smaller in size in the Y direction.

[0015] A fourth aspect of the connector is the third aspect of the connector, wherein the connector comprises a fixed housing fixed to the attachment object, the fixed housing having a fixed side limiting portion, and the fixed side limiting portion is configured to abut against the displacement portion when the displacement portion is displaced in the Y direction, thereby limiting the Y direction position of the displacement portion relative to the fixed housing within a predetermined range.

[0016] In the above aspect, the connector includes a fixed housing fixed to an attachment object, and the fixed housing has a fixed-side limiting portion, which limits the position of the displacement portion in the Y direction relative to the fixed housing within a predetermined range. Therefore, in the manufacturing process of the connector, the position of the displacement portion relative to the fixed housing is determined to some extent before the movable housing is assembled to the fixed housing, facilitating assembly of the movable housing.

[0017] A connector according to a fifth aspect is the connector of any one of the first to fourth aspects, wherein the contact portion contacts the object to be connected so as to sandwich the object to be connected in the X direction.

[0018] In the above aspect, the contact portion comes into contact with the connection object so as to sandwich the connection object in the X direction, which makes it easy to make the displacement portion follow the positional deviation of the connection object in the X direction.

[0019] The connector of the sixth aspect is any one of the first to fifth aspects, wherein the displacement portion has an elastic deformation portion that elastically deforms when the connection object is connected, and a deformation limiting portion that abuts against the elastic deformation portion to limit the amount of deformation of the elastic deformation portion.

[0020] In the above aspect, the displacement portion has an elastic deformation portion that elastically deforms when the connection object is connected, so that the contact portion can be brought into elastic contact with the connection object. However, since the displacement portion is displaceable relative to the movable housing, it is difficult to limit the deformation of the elastic deformation portion with the movable housing. Therefore, the displacement portion further includes a deformation limiting portion that abuts against the elastic deformation portion to limit the amount of deformation of the elastic deformation portion. Therefore, the deformation limiting portion limits excessive deformation of the displacement portion, preventing plastic deformation of the elastic deformation portion.

[0021] A seventh aspect of the connector is any of the first to sixth aspects, wherein the displacement portion includes a first side plate and a second side plate, both of which have their thickness directions oriented in the Y direction and which face each other in the Y direction, and a connecting plate, whose thickness direction is oriented in the X direction and which connects the first side plate and the second side plate in the Y direction, and which contacts the connection object from one side in the X direction, a contact piece base extending from the first side plate toward the second side plate, and a contact piece extending from the contact piece base and elastically contacting the connection object from the other side in the X direction, wherein a limiting hole is formed in the second side plate, and the tip of the contact piece base is positioned in the limiting hole, thereby limiting the deformation amount of the contact piece base.

[0022] In the above aspect, the limiting hole is formed in the second side plate, and the tip of the contact piece base is disposed in the limiting hole, thereby limiting the deformation amount of the contact piece base. This realizes, with a simple configuration, a deformation limiting portion that limits the deformation amount of the elastic deformation portion that includes the contact piece base and the contact piece.

[0023] In an eighth aspect of the connector, in the first aspect, the movable housing has a movable-side limiting portion, and the movable-side limiting portion is configured so that when the movable housing is displaced in the X direction, the movable-side limiting portion abuts against the displacement portion, thereby limiting the position of the displacement portion in the X direction relative to the movable housing to a predetermined range, and the displacement portion has a first side plate and a second side plate, both of which have their plate thickness directions oriented in the Y direction and which face each other in the Y direction, and a plate thickness direction of the displacement portion is oriented in the X direction, and the first side plate and the second side plate are configured so that the displacement portion abuts against the displacement portion in the Y direction a connecting plate that connects the first and second side plates by connecting the first and second side plates in such a manner that the connecting plate comes into contact with the connection object from one side in the X direction, a contact piece base that extends from the first side plate toward the second side plate, and a contact piece that extends from the contact piece base and elastically comes into contact with the connection object from the other side in the X direction, wherein both the end of the first side plate on the other side in the X direction and the end of the second side plate on the other side in the X direction are configured to be able to abut on the movable-side limiting portion, and the end of the first side plate on the other side in the X direction is located on one side in the X direction of the end of the second side plate on the other side in the X direction.

[0024] In the above aspect, the contact piece base extends from the first side plate, and the contact piece extends from the contact piece base, and the end of the first side plate on the other side in the X direction is located on one side in the X direction with respect to the end of the second side plate on the other side in the X direction. Therefore, when the displacement portion is made by cutting and bending a plate material, the width dimension of the contact piece can be made large. In addition, both the end of the first side plate on the other side in the X direction and the end of the second side plate on the other side in the X direction are configured to be able to abut against the movable-side limiting portion, which prevents the displacement portion from losing its posture due to the movable-side restricted portion abutting against the displacement portion.

[0025] The connector according to the ninth aspect is any one of the first to eighth aspects, wherein the terminal has an avoidance portion extending from the displacement portion, the avoidance portion extending in a direction away from the connection axis of the connection object.

[0026] In a mode in which the portion of the terminal extending from the displacement portion extends, for example, parallel to the connection axis of the connection object, there is a risk that this portion may collide with the tip of the connection object. Therefore, in the above aspect, the terminal has an avoidance portion that extends from the displacement portion in a direction away from the connection axis of the connection object, thereby preventing the above-mentioned collision.

[0027] The connector according to a tenth aspect is based on any one of the first to ninth aspects, and is configured such that the movable housing is supported by contacting the attachment object or a support member that does not displace relative to the attachment object.

[0028] In the first mode, since the displacement portion is displaceable relative to the movable housing, the movable housing cannot be properly supported by the displacement portion. Therefore, in the above aspect, the movable housing is supported by contacting the attachment object or the support member that does not displace relative to the attachment object, thereby making it possible to properly support the movable housing.

[0029] In the embodiments described below, the support member is a fixed housing, but the support member is not limited to this. For example, the support member may be a portion of the terminal that does not move relative to the attachment object.

[0030] The connector of the 11th aspect is any one of the first to ninth aspects, in which the movable housing is supported by contacting a support member that does not displace relative to the attachment object, and the movable housing and the support member are in a state in which one clamps the other.

[0031] In the above-described embodiment, the movable housing and the support member are in a state in which one clamps the other. This prevents the movable housing from rattling relative to the support member. Preventing rattling of the movable housing prevents, for example, the movable housing from rattling and striking a connection object or terminal in a connected state, which could result in the contact points between the terminal and the connection object sliding and being scraped.

[0033] A connector 10 according to an embodiment of the present disclosure will be described below.

[0034] For ease of explanation, the X direction shown in each drawing may be referred to as the front-to-rear direction, the Y direction as the width direction (left-to-right direction), and the Z direction as the up-to-down direction. These terms indicating directions are directional concepts based on connector 10, and do not limit the installation direction or posture of connector 10 when in use.

[0035] 1 to 4 show a connector 10. The connector 10 includes a plurality of (five) terminals 20, a fixed housing 30, a movable housing 40, and a plurality of mounting fittings 50.

[0036] 4, the connector 10 is configured to be mountable to a substrate 90, which is an "object to be mounted." In this embodiment, the connector 10 is mounted to the substrate 90 by soldering a plurality of terminals 20 and a plurality of mounting brackets 50 to the substrate 90.

[0037] The connector 10 is configured to be connectable to mating terminals 80 (see FIGS. 11 to 13) as "connection objects." In this embodiment, it is configured to be connectable to a plurality (five) of mating terminals 80. The mating terminals 80 can be connected from above. In other words, the connection direction of the mating terminals 80 to the connector 10 is downward (-Z direction).

[0038] (Terminal 20) 5 and 6 show the terminal 20. The terminal 20 is made of a conductive material and electrically connects the substrate 90 and the mating terminal 80.

[0039] The terminal 20 has a board connecting portion 21, a held portion 22, an intermediate deformation portion 23, and a displacement portion 24 in this order.

[0040] The board connection portion 21 is a portion that is connected to the board 90. The board connection portion 21 is surface-mounted on the board 90 by soldering.

[0041] The held portion 22 is a portion that is held by the fixed housing 30. The held portion 22 is press-fitted into the fixed housing 30 and is thereby held by the terminal holding portion 31 of the fixed housing 30. The held portion 22 is press-fitted into the fixed housing 30 from above. The plate thickness direction of the held portion 22 is oriented in the front-to-rear direction.

[0042] The intermediate deformation portion 23 is located between the held portion 22 and the displacement portion 24, and is a portion that is formed to be easily elastically deformed.

[0043] The displacement portion 24 is a portion that can be displaced relative to the board connecting portion 21 and the held portion 22. The displacement of the displacement portion 24 is achieved by deformation of the intermediate deformation portion 23. The displacement portion 24 is formed with contact portions 24c1 and 24f1 that come into contact with the mating terminal 80.

[0044] The intermediate deformation portion 23 has, in this order, an upward portion 23a, a first front portion 23b, a downward portion 23c, a second front portion 23d, and an inclined portion 23e (avoidance portion). The upward portion 23a extends linearly upward from the held portion 22. The upward portion 23a is located at the same position as the held portion 22 in the front-rear direction. The first front portion 23b extends linearly forward from a curved portion formed on the upper side of the upper portion 23a. The first front portion 23b is located above a lower bead 24c1, which will be described later. The downward portion 23c extends linearly downward from a curved portion formed on the front side of the first front portion 23b. The second front portion 23d extends linearly in the front direction from a curved portion formed on the lower side of the downward portion 23c. The inclined direction portion 23e extends in a straight line obliquely forward and upward from a curved portion formed on the front side of the second front direction portion 23d. The angle formed between the extension direction of the inclined direction portion 23e and the up-down direction is less than 45 degrees. The lower end of the inclined direction portion 23e is located below the lower end of the displacement portion 24, and the upper end of the inclined direction portion 23e is located above the lower end of the displacement portion 24.

[0045] The intermediate deformation portion 23 is formed by bending a plate material in the plate thickness direction. The plate thickness direction of the intermediate deformation portion 23 is oriented in a direction perpendicular to the Y direction (direction in the ZX plane) over its entire range.

[0046] As described above, in the intermediate deformation section 23 of this embodiment, the portion connecting the upward section 23a and the downward section 23c is configured with the first front section 23b and a pair of curved portions in front and behind the first front section 23b. With this configuration, stress generated in the intermediate deformation section 23 can be dispersed more effectively than in an embodiment in which the portion connecting the upward section 23a and the downward section 23c is configured to be curved so as to form a semicircular shape in side view.

[0047] The displacement portion 24 has a first side plate 24a, a second side plate 24b, and a connecting plate 24c. The first side plate 24a and the second side plate 24b face each other in the width direction, with the plate thickness direction of both plates facing the width direction. The connecting plate 24c has its thickness oriented in the front-rear direction and connects the rear ends of the first side plate 24a and the second side plate 24b in the width direction. The lower end of the connecting plate 24c is connected to the intermediate deformation portion 23. The connecting plate 24c has beads 24c1 formed in two locations that extend in the width direction and protrude forward. The beads 24c1 function as first contact portions 24c1 that contact the mating terminal 80 from one side in the X direction (the -X direction side in this embodiment).

[0048] A through hole 24d is formed in the vertical middle of the curved portion formed between the first side plate 24a and the connecting plate 24c, and a through hole 24d is also formed in the vertical middle of the curved portion formed between the second side plate 24b and the connecting plate 24c. The formation of these through holes 24d reduces rigidity, allowing the curved portion to be formed with a small force.

[0049] The displacement portion 24 also has a contact piece base portion 24e and a contact piece 24f. The contact piece base 24e extends from the first side plate 24a and extends in the width direction toward the second side plate 24b. The tip of the contact piece base 24e is disposed in a restricting hole 24g formed in the second side plate 24b. In a free state, the contact piece base 24e extends toward the tip side substantially parallel to the Y direction, but more specifically, extends in a direction slightly inclined relative to the Y direction toward the connecting plate 24c (the -X direction). The contact piece 24f extends upward from the contact piece base 24e. The contact piece 24f has a mountain-shaped contact portion 24f1 at the tip and an elastic support portion 24f2 that supports the mountain-shaped contact portion 24f1. The mountain-shaped contact portion 24f1 is bent into a mountain shape so that it protrudes toward the mating terminal 80. The apex of the mountain-shaped contact portion 24f1 is located between the two beads 24c1 of the connecting plate 24c in the vertical direction. The width of the elastic support portion 24f2 is smaller than the width of the mountain-shaped contact portion 24f1. The terminal 20 is configured to contact the mating terminal 80 at three points: the two beads 24c1 of the connecting plate 24c as the first contact portion 24c1, and the mountain-shaped contact portion 24f1 as the second contact portion. Furthermore, the two beads 24c1 of the connecting plate 24c as the first contact portion 24c1 and the angle-shaped contact portion 24f1 as the second contact portion are formed so that their width dimension is larger than the width dimension of the mating terminal 80. As a result, the displacement portion 24 is configured so that the mating terminal 80 and the contact portions 24c1, 24f1 come into appropriate contact with each other even if the mating terminal 80 is misaligned in the Y direction.

[0050] The first side plate 24a has a front edge 24a1 that extends in the vertical direction. When the displacement portion 24 is displaced forward relative to the movable housing 40, the front edge 24a1 of the first side plate 24a abuts against the movable housing 40. The first side plate 24a has a smaller front-to-rear dimension at its lower part than at its upper part. A contact piece base 24e extends from the front edge of the lower part of the first side plate 24a via a curved portion. The front edge 24a1 is the front edge of the upper part of the first side plate 24a. The length (vertical length) of the front edge 24a1 exceeds 50% of the vertical dimension of the first side plate 24a.

[0051] The second side plate 24b has a front edge 24b1 that extends in the vertical direction. The front edge 24b1 of the second side plate 24b abuts against the movable housing 40 when the displacement portion 24 is displaced forward relative to the movable housing 40. Unlike the first side plate 24a, the second side plate 24b has a constant front-to-rear dimension in the up-down direction. A front edge 24b1 of the second side plate 24b is formed from the lower end to the upper end of the second side plate 24b. A front edge 24b1 of the second side plate 24b is located further forward than a front edge 24a1 of the first side plate 24a.

[0052] The first side plate 24a has a lower edge 24a2 extending in the front-rear direction. When the displacement portion 24 is displaced downward relative to the fixed housing 30, the lower edge 24a2 of the first side plate 24a abuts against the fixed housing 30. The second side plate 24b has a lower edge 24b2 extending in the front-rear direction. When the displacement portion 24 is displaced downward relative to the fixed housing 30, the lower edge 24b2 of the second side plate 24b abuts against the fixed housing 30. The lower edge 24a2 of the first side plate 24a and the lower edge 24b2 of the second side plate 24b are formed at the same position in the vertical direction. The lower edge 24a2 of the first side plate 24a and the lower edge 24b2 of the second side plate 24b are located below the upper end of the inclined direction portion 23e of the intermediate deformation portion 23 and above the lower end of the inclined direction portion 23e.

[0053] The first side plate 24a has an upper edge 24a3 extending in the front-rear direction. When the displacement portion 24 is displaced upward relative to the movable housing 40, the upper edge 24a3 of the first side plate 24a abuts against the lower surface 41b (see FIG. 11) of the top wall 41 of the movable housing 40. The second side plate 24b has an upper edge 24b3 extending in the front-rear direction. When the displacement portion 24 is displaced downward relative to the movable housing 40, the upper edge 24b3 of the second side plate 24b abuts against the lower surface 41b of the top wall 41 of the movable housing 40. An upper edge 24a3 of the first side plate 24a and an upper edge 24b3 of the second side plate 24b are formed at the same position in the up-down direction.

[0054] A carrier cutting portion 24h protrudes upward from the upper end of the connecting plate 24c. The carrier cutting portion 24h is a connecting portion between the terminal 20 and the carrier when the terminal 20 is formed by progressive processing. The upper end of the carrier cutting portion 24h is located above the upper edge 24a3 of the first side plate 24a and the upper edge 24b3 of the second side plate 24b. Above the position where the carrier cutting portion 24h is located on the movable housing 40, a recess 41d (see FIG. 11) recessed upward is formed. This prevents the carrier cutting portion 24h from coming into contact with the movable housing 40 even when the displacement portion 24 is displaced upward.

[0055] (Fixed housing 30) The fixed housing 30 is integrally formed from an insulating material such as synthetic resin.

[0056] The fixed housing 30 is fixed to the substrate 90 and does not move relative to the substrate 90. Specifically, the fixed housing 30 is attached to the substrate 90 via a plurality of terminals 20 and a plurality of mounting brackets 50.

[0057] The fixed housing 30 has a terminal holding portion 31 that holds the held portion 22 of the terminal 20 . 8, the terminal holding portion 31 has a plurality of (six) press-fit walls 31a. The press-fit walls 31a are arranged side by side in the terminal arrangement direction (Y direction). The held portion 22 of the terminal 20 is press-fitted between adjacent press-fit walls 31a. The terminal holding portion 31 also has a connecting wall 31b. The connecting wall 31b connects the multiple press-fit walls 31a in the terminal arrangement direction. The connecting wall 31b is formed on the outer side in the front-rear direction (the rear side, the -X direction side in this embodiment) of the multiple press-fit walls 31a.

[0058] The terminal 20 is assembled to the fixed housing 30 in a downward direction. Therefore, when the held portion 22 of the terminal 20 is press-fitted between the press-fit walls 31a of the fixed housing 30, the board connecting portion 21 of the terminal 20 interferes with the connecting wall 31b. Therefore, in this embodiment, when the terminal 20 is assembled to the fixed housing 30, the board connecting portion 21 of the terminal 20 is not formed, and the portion that will become the board connecting portion 21 extends straight downward from the held portion 22. After the held portion 22 of the terminal 20 is press-fitted between the press-fit walls 31a of the fixed housing 30, the portion that will become the board connecting portion 21 is bent, and the terminal 20 is completed.

[0059] The fixed housing 30 has a mounting bracket holding portion 32 that holds the mounting bracket 50 . The mounting bracket holding portions 32 are formed at outer positions in the width direction of the fixed housing 30. A total of four mounting bracket holding portions 32 are formed. Two of the four mounting bracket holding portions 32 are formed on the front side of the center position of the fixed housing 30 in the front-to-rear direction, and the other two are formed on the rear side of the center position of the fixed housing 30 in the front-to-rear direction.

[0060] The fixed housing 30 has a reinforcing portion 33 formed between the front mounting bracket holding portion 32 and the rear mounting bracket holding portion 32. A positioning boss 33a is formed on the underside of the reinforcing portion 33. As shown in Figure 3, a side surface 33b of the reinforcing portion 33 is located widthwise outward of the tip (widthwise outer end) of the tail portion of the mounting bracket 50. A downwardly recessed recess 33c is formed on the upper surface of the reinforcing portion 33.

[0061] The fixed housing 30 has a pair of tail protection portions 34. As shown in Fig. 3, the plurality of board connection portions 21 of the plurality of terminals 20 are arranged between the pair of tail protection portions 34.

[0062] 7, the fixed housing 30 has an arrangement space 35 in which the displacement portion 24 of the terminal 20 and movable-side limiting portions 42, 43 (described later) are arranged. A plurality of (five) arrangement spaces 35 are formed to match the number of terminals 20.

[0063] The arrangement space 35 is formed by an arrangement bottom surface 35a, a pair of arrangement side surfaces 35b, and an arrangement rear surface 35c.

[0064] The arrangement bottom surface 35a is configured to be in contact with the displacement portion 24 displaced downward. Specifically, the arrangement bottom surface 35a is configured to be in contact with both lower ends 24a2, 24b2 of the pair of side plates (first side plate 24a and second side plate 24b) of the displacement portion 24 displaced downward at the same time. When connecting the mating terminal 80 to the connector 10, the displacement portion 24 receives a downward force from the mating terminal 80, displaces downward, and abuts against the arrangement bottom surface 35a (not shown). Then, the displacement portion 24 does not displace downward any further, and the mating terminal 80 is connected to the displacement portion 24. The arrangement bottom surface 35a is a flat surface with its normal direction facing upward.

[0065] In addition, when the connector 10 and the mating terminal 80 are connected, the displacement portion 24 is basically not in contact with the arrangement bottom surface 35a. Due to some cause (such as vertical vibration of the mating terminal 80), the mating terminal 80 may be temporarily displaced downward relative to the connector 10. When the mating terminal 80 is temporarily displaced downward relative to the connector 10, the mating terminal 80 is inserted deeper into the displacement portion 24 of the terminal 20. When the temporary downward displacement of the mating terminal 80 is released and the mating terminal 80 returns to its normal position, the displacement portion 24 displaces upward together with the mating terminal 80. Immediately after connecting the mating terminal 80 to the connector 10, the displacement portion 24 may be in contact with the arrangement bottom surface 35a, but due to the phenomenon described above, in the connected state, the displacement portion 24 is basically not in contact with the arrangement bottom surface 35a.

[0066] The arrangement side surface 35b is configured to abut against the displacement portion 24 displaced in the width direction. Specifically, the arrangement side surface 35b is configured to abut against the widthwise outer surfaces of the pair of side plates (first side plate 24a and second side plate 24b) of the displacement portion 24 displaced in the width direction. The arrangement side surface 35b is a flat surface whose normal direction is oriented in the width direction. In a normal connection state, the displacement portion 24 is not in contact with the arrangement side surface 35b.

[0067] The plurality of arrangement side surfaces 35b and the plurality of arrangement rear surfaces 35c that form the plurality of arrangement spaces 35 are constituted by a pair of side walls 36 and a plurality (four) of partition walls 37 of the fixed housing 30. The top surface 36 a of the side wall 36 is in contact with the top wall 41 of the movable housing 40 . Each of the plurality of partition walls 37 is disposed between adjacent displacement portions 24 among the plurality of displacement portions 24. Each of the plurality of partition walls 37 has the same structure. An upper surface 37a of the partition wall 37 is flush with the upper surface 36a of the side wall 36. A guide protrusion 37b protruding upward is formed on the upper surface 37a of the partition wall 37. A portion of the upper surface 37a of the partition wall 37 located in front of the guide protrusion 37b is in contact with the top wall 41 of the movable housing 40.

[0068] A confirmation hole 35a1 is formed in the arrangement bottom surface 35a. The confirmation hole 35a1 is a hole that makes the displacement portion 24 of the terminal 20 visible from the lower side of the connector 10. By checking the displacement portion 24 through the confirmation hole 35a1, it is possible to check the connection state between the displacement portion 24 and the connection object 80. Note that the confirmation hole 35a1 is formed to be large enough to make it possible to check the connection state between the displacement portion 24 and the connection object 80 even when the displacement portion 24 is displaced to the limit of its displacement.

[0069] The fixed housing 30 has housing front abutment portions that abut when the movable housing 40 is displaced forward, thereby limiting the range of forward movement of the movable housing 40 relative to the fixed housing 30. In this embodiment, the pair of side walls 36 function as the housing front abutment portions.

[0070] The fixed housing 30 has a housing rear abutment portion that abuts against the movable housing 40 when the movable housing 40 is displaced rearward. This limits the range of rearward movement of the movable housing relative to the fixed housing 30. In this embodiment, the pair of side walls 36 and the multiple partition walls 37 function as the housing rear abutment portion. Specifically, rear arrangement surfaces 35c formed on the pair of side walls 36 and the multiple partition walls 37 function as the housing rear abutment portion. The rear arrangement surface 35c abuts against the second abutment wall 43 of the movable housing 40.

[0071] The fixed housing 30 has a pair of clamping portions 38. The pair of clamping portions 38 are portions that clamp the movable housing 40. The pair of clamping portions 38 are configured so that the distance between the pair of clamping portions 38 can be slightly increased. Specifically, each of the pair of clamping portions 38 is formed in the shape of a cantilever beam extending upward. The clamping portions 38 clamp the movable housing 40 at their tip ends (free ends). The clamping portion 38 is formed with a through hole 38a that passes through the clamping portion 38 in the width direction. This makes the clamping portion 38 more easily deformable and also enables a locked portion 46c of the movable housing 40, which will be described later, to be locked. An inclined guide surface 38b is formed on the clamping portions 38. This makes it easier for the movable housing 40 to enter between the pair of clamping portions 38.

[0072] (movable housing 40) The movable housing 40 is integrally formed from an insulating material such as synthetic resin.

[0073] The movable housing 40 has a top wall 41 that forms the upper portion of the movable housing 40 . The movable housing 40 has a plurality of insertion openings 44 into which the mating terminals 80 are inserted. The mating terminals 80 come into contact with the terminals 20 inside the insertion openings 44, ensuring dustproofness. The insertion openings 44 penetrate the top wall 41 in the vertical direction.

[0074] As shown in Fig. 3, when viewed from the Z direction, which is the connection direction, the insertion opening 44 has a rectangular shape with its short side in the X direction and its long side in the Y direction. The X direction dimension of the insertion opening 44 is slightly larger than the X direction dimension of the mating terminal 80, for example, 1.05 to 1.15 times (see Fig. 13). The Y direction dimension of the insertion opening 44 is at least twice the Y direction dimension of the mating terminal 80. The cross-sectional shape of the mating terminal 80 is square. As a result, the insertion opening 44 has a dimension that allows for a small margin relative to the mating terminal 80 in the direction in which the movable housing 40 can be displaced (X direction), and a dimension that allows for a large margin relative to the mating terminal 80 in the direction in which the movable housing 40 cannot be displaced (Y direction).

[0075] The movable housing 40 has inclined surfaces 45a and 45b, which are formed to correspond to the multiple insertion openings 44, respectively. The inclined surfaces 45a and 45b include an X-direction inclined surface 45a and a Y-direction inclined surface 45b. The X-direction inclined surfaces 45a are formed on both the +X-direction side and the −X-direction side of the insertion opening 44. The X-direction inclined surfaces 45a are planes whose normal direction is inclined in the X-direction toward the +Z direction. For example, as shown in FIG. 11 , if a mating terminal 80 is inserted while misaligned in the −X direction with respect to the insertion opening 44, the tip of the mating terminal 80 abuts against the X-direction inclined surface 45a on the −X-direction side of the insertion opening 44. If the insertion continues, the movable housing 40 receives a −X-direction force from the mating terminal 80 via the X-direction inclined surface 45a. This force displaces the movable housing 40 in the −X direction. In other words, the X-direction inclined surface 45a functions to eliminate misalignment in the X direction between the movable housing 40 and the mating terminal 80. The Y-direction inclined surface 45b is an inclined surface that facilitates removal of the mold used to form the insertion opening 44 during resin molding of the movable housing 40. The Y-direction dimension of the Y-direction inclined surface 45b is smaller than the X-direction dimension of the X-direction inclined surface 45a, specifically, is 0.4 times or less. The inclined surfaces 45a and 45b are formed to connect the upper surface 41a of the top wall 41 and the upper end of the insertion opening 44.

[0076] The movable housing 40 has upward contact surfaces 41b and 41c (see FIG. 9) that come into contact with the fixed housing 30 from above. The upward contact surfaces 41b, 41c are flat surfaces whose normal direction faces downward. The upward contact surfaces 41b, 41c are the lower surfaces of the top wall 41. The upward contact surfaces 41b, 41c include a pair of first upward contact surfaces 41b located outward in the width direction from the plurality of first abutment walls 42 and the plurality of second abutment walls 43, and a plurality (four) of second upward contact surfaces 41c located between adjacent first abutment walls 42. The first upward contact surface 41b contacts the upper surfaces 36a of the pair of side walls 36 of the fixed housing 30. The second upward contact surface 41c contacts the upper surfaces 37a of the partition walls 37 of the fixed housing 30. The upper surfaces 36a of the pair of side walls 36 and the upper surfaces 37a of the plurality of partition walls 37 are in contact with the movable housing 40, thereby stabilizing the orientation of the movable housing 40 relative to the fixed housing 30.

[0077] The movable housing 40 has movable-side limiting portions 42 and 43. The movable-side limiting portions 42 and 43 are configured so that when the movable housing 40 is displaced in the X direction, the movable-side limiting portions 42 and 43 come into contact with the displacement portion 24, thereby limiting the position of the displacement portion 24 in the X direction relative to the movable housing 40 within a predetermined range. This allows the displacement portion 24 to follow the movable housing 40 to some extent when the movable housing 40 is displaced in the front-to-rear direction.

[0078] The movable-side limiting portions 42 and 43 are configured from a plurality of first contact walls 42 and a plurality of second contact walls 43 . A plurality of second abutment walls 43 are located behind each of the plurality of first abutment walls 42. A displacement portion 24 is disposed behind the first abutment walls 42 and in front of the second abutment walls 43. Between the first abutment wall 42 and the second abutment wall 43, the displacement portion 24 is displaceable to a certain extent in the front-rear direction.

[0079] As shown in Fig. 10, the first abutment wall 42 has a general rear surface 42a. The general rear surface 42a of the first abutment wall 42 is a flat surface with a normal direction facing rearward. The general rear surface 42a of the first abutment wall 42 is configured to be able to abut against the second side plate 24b of the displacement portion 24. As shown in Fig. 11, the general rear surface 42a faces the contact piece 24f in the front-rear direction.

[0080] The first abutment wall 42 has a protruding rear surface 42b1. The protruding rear surface 42b1 is configured to be able to abut against the first side plate 24a of the displacement portion 24. The protruding rear surface 42b1 is a flat surface with its normal direction facing rearward. The protruding rear surface 42b1 is located rearward of the general rear surface 42a. The gap in the front-to-rear direction between the protruding rear surface 42b1 and the first side plate 24a of the displacement portion 24 is the same as the gap in the front-to-rear direction between the general rear surface 42a and the second side plate 24b of the displacement portion 24. The first abutment wall 42 is formed with a protruding portion 42b that protrudes rearward beyond the general rear surface 42a. The protruding portion 42b is formed at the right end of the first abutment wall 42. The protruding portion 42b is formed across from the upper end to the lower end of the first abutment wall 42. The protruding rear surface 42b1 is formed on the protruding portion 42b.

[0081] 9, the second contact wall 43 has a front surface 43a. The front surface 43a of the second contact wall 43 is configured to be able to come into contact with the connecting plate 24c of the displacement portion 24. A groove 43c is formed on the front surface 43a side of the second abutment wall 43, extending vertically through the center of the width direction of the front surface 43a. The groove 43c functions as a space for burrs to escape if any remain on the carrier cutting portion 24h. That is, if burrs come into contact with the movable housing 40 (the front surface 43a of the second abutment wall 43) during assembly of the movable housing 40, shavings may be generated from the movable housing 40, but this groove 43c prevents this generation. The upper side of the groove 43c is connected to the recess 41d.

[0082] 10 , the second abutment wall 43 has a rear surface 43b. When the movable housing 40 is displaced rearward, the rear surface 43b of the second abutment wall 43 abuts against the rear arrangement surface 35c of the fixed housing 30. This limits the range of movement of the movable housing 40 in the rear direction relative to the fixed housing 30.

[0083] The movable housing 40 has a pair of side walls 46. The pair of side walls 46 are walls that protrude downward from the lower surface 41b of the top wall 41, and are formed on both outer sides in the width direction at the rear of the movable housing 40. A front surface 46a (see FIG. 9) of the side wall 46 abuts against the side wall 36 of the fixed housing 30 when the movable housing 40 is displaced forward. This limits the range of forward movement of the movable housing 40 relative to the fixed housing 30.

[0084] The movable housing 40 has a rear wall 47. The rear wall 47 connects the rear ends of the pair of side walls 46 together in the width direction.

[0085] The movable housing 40 has a pair of clamped portions 46b. The pair of clamped portions 46b are portions that are clamped by the clamping portions 38 of the fixed housing 30 from the outer sides in the width direction. The sandwiched portion 46b protrudes outward in the width direction relative to the side wall 46. The sandwiched portion 46b is located in the middle of the side wall 46 in the front-rear direction, and is formed over the entire side wall 46 in the up-down direction.

[0086] The movable housing 40 has a pair of locked portions 46c. The pair of locked portions 46c are portions that are locked by the clamping portions 38 of the fixed housing 30. This prevents the movable housing 40 from coming off the fixed housing 30 in the upward direction. The locked portions 46c are formed below the clamped portions 46b and protrude outward in the width direction relative to the clamped portions 46b. The locked portions 46c are formed with inclined surfaces that make it easier to push the pair of locked portions 46c into the pair of clamping portions 38 of the fixed housing 30.

[0087] (Connection behavior) Next, the operation of the connector 10 when the mating terminal 80 is connected will be described.

[0088] 11, when connection is made with the mating terminal 80 misaligned in the −X direction, the tip of the mating terminal 80 abuts against the X-direction inclined surface 45a of the movable housing 40. This causes the movable housing 40 to displace in a direction (−X direction) that eliminates the misalignment. When the displacement of the movable housing 40 is relatively large, the movable-side limiting portions 42, 43 (specifically, the first abutment wall 42) of the movable housing displacing in the -X direction come into contact with the displacement portion 24 of the terminal 20, and the displacement portion 24 is displaced in the same direction (-X direction). As a result, the displacement portion 24 remains within a positional range (a positional range relative to the movable housing 40) in which it can be connected to the mating terminal 80 inserted from the insertion opening 44.

[0089] 12 shows the state at the moment when the displacement of the movable housing 40 is completed and the mating terminal 80 comes into contact with the displacement portion 24 of the terminal 20. In this state, the displacement portion 24 is in contact with the first abutment wall 42 of the movable housing 40.

[0090] As the connection proceeds further, the displacement portion 24 separates from the first abutment wall 42 of the movable housing 40 as the mating terminal 80 is connected. Then, the displacement portion 24 is no longer in contact with either the first abutment wall 42 or the second abutment wall 43 of the movable housing 40, and the connection process is completed (see FIG. 13). In this way, the structure of the connector 10, including the insertion port 44 and the movable side limiting portions 42, 43, is determined so that the displacement portion 24 is not in contact with the movable side limiting portions 42, 43 of the movable housing 40 when the connection work is completed.

[0091] Although the above description has been given for the case of misalignment in the -X direction, the same operation occurs in the case of misalignment in the +X direction.

[0092] <Action and effect> Next, the effects of this embodiment will be described.

[0093] 4, in this embodiment, the connector 10 includes a movable housing 40 that is displaceable in the X direction, which is a direction perpendicular to the connection direction, relative to the attachment object 90, and a terminal 20 that electrically connects the attachment object 90 and the connection object 80. The terminal 20 has a displacement portion 24 that is displaceable in the X direction relative to the attachment object 90. The displacement portion 24 is formed with contact portions 24c1 and 24f1 that come into contact with the connection object 80. In this way, since both the movable housing 40 and the displacement portion 24 can be displaced in the X direction relative to the attachment object 90, when connecting the connector 10 and the connection object 80, the movable housing 40 and the displacement portion 24 can be displaced to match the positional deviation of the connection object 80 in the X direction.

[0094] Furthermore, in this embodiment, the displacement portion 24 is displaceable relative to the movable housing 40 . Therefore, unlike the prior art (in which, when the displacement portion is displaced, the movable housing also displaces integrally with the displacement portion), the mass of the portion that displaces integrally with the displacement portion 24 is small. This reduces the inertial force acting on the portion that displaces integrally. Furthermore, the resonant frequency of the displacement portion 24 of the connector 10 when connected to the connection object 80 can be increased, making it easier to prevent the frequency (natural frequency) of the displacement portion 24 of the connector 10 from coinciding with the frequencies of automobile engine vibrations, road vibrations, and the like. As a result, wear of the contact portions 24c1 and 24f1 and breakage of the intermediate deformation portion 23 can be prevented.

[0095] Since the displacement portion 24 is displaceable relative to the movable housing 40 , when the movable housing 40 is displaced relative to the attachment object 90 , the displacement portion 24 is displaced relative to the movable housing 40 . In this embodiment, the movable housing 40 has movable-side limiting portions 42 and 43. The movable-side limiting portions 42 and 43 are configured so that when the movable housing 40 is displaced in the X direction, the movable-side limiting portions 42 and 43 come into contact with the displacement portion 24, thereby limiting the position of the displacement portion 24 in the X direction relative to the movable housing 40 within a predetermined range. Therefore, for example, by displacing the movable housing 40 in accordance with the positional deviation of the connection object 80 in the X direction prior to contact between the connection object 80 and the terminal 20 (see FIG. 12), the displacement portion 24 can be displaced in advance in accordance with the positional deviation of the connection object 80 in the X direction before contact between the connection object 80 and the terminal 20. As a result, the distance of the positional deviation that can be accommodated can be made longer compared to an embodiment in which the positional deviation of the connection object 80 is accommodated only by the structure of the terminal 20.

[0096] Furthermore, in this embodiment, the movable housing 40 cannot be displaced in the Y direction, which is the arrangement direction of the multiple displacement portions 24. Therefore, there is no need to provide a structure for displacing the movable housing 40 in the Y direction, and as a result, for example, the connector 10 can be made smaller in size in the Y direction. In addition, in this embodiment, the Y-direction dimension of the insertion opening 44 is at least twice the Y-direction dimension of the mating terminal 80. Therefore, even if the mating terminal 80 is misaligned in the Y direction, the mating terminal 80 can enter the insertion opening 44. Furthermore, in this embodiment, the displacement portion 24 is configured so that the mating terminal 80 and the contact portions 24c1, 24f1 come into appropriate contact with each other even if the mating terminal 80 is misaligned in the Y direction. Therefore, the displacement portion 24 can accommodate misalignment of the mating terminal 80 in the Y direction without being displaced in the Y direction. As described above, the positional deviation of the mating terminal 80 in the Y direction can be accommodated by the insertion opening 44 having a large Y-direction dimension and the displacement portion 24 having a large Y-direction dimension. Since the displacement in the Y direction can be accommodated without displacing the displacement portion 24 in the Y direction, deformation of the intermediate deformation portion 23 that displaces the displacement portion 24 in the Y direction is unlikely to occur. If the intermediate deformation portion 23 does not need to deform to absorb positional misalignment in the Y direction, the stress generated by such deformation (deformation required for displacement of the displacement portion 24 in the Y direction) is reduced, so the amount of elastic deformation in the X direction of the intermediate deformation portion 23 during the connection work (displacement amount of the displacement portion) and the amount of elastic deformation in the Z direction of the intermediate deformation portion 23 after connection (displacement amount of the displacement portion) can be set large. Furthermore, in this embodiment, the thickness direction of the intermediate deformation portion 23 is oriented in a direction (direction within the ZX plane) perpendicular to the direction (Y direction) in which the movable housing 40 cannot be displaced over its entire range. Therefore, the deformation of the intermediate deformation portion 23 is mainly in the thickness direction, and damage to the intermediate deformation portion 23 is prevented.

[0097] In this embodiment, the connector 10 includes a fixed housing 30 that is fixed to the attachment object 90, and the fixed housing 30 has fixed-side limiting portions 36, 37 (side wall 36 and partition wall 37 of the fixed housing 30). That is, the fixed-side limiting portions 36, 37 of the fixed housing 30 limit the position of the displacement portion 24 in the Y direction relative to the fixed housing 30 within a predetermined range. Therefore, in the manufacturing process of the connector 10, the position of the displacement portion 24 relative to the fixed housing 30 is determined to some extent before the movable housing 40 is assembled to the fixed housing 30, making assembly of the movable housing 40 easier.

[0098] Furthermore, in this embodiment, the contact portions 24c1 and 24f1 contact the connection object 80 so as to sandwich the connection object 80 in the X direction. This makes it easy to make the displacement portion 24 follow the positional deviation of the connection object 80 in the X direction.

[0099] In the present embodiment, the displacement portion 24 has elastic deformation portions 24e, 24f (contact piece base portion 24e, contact piece 24f) that are elastically deformed when the connection object 80 is connected. Therefore, the contact portion 24f1 can be brought into elastic contact with the connection object 80. However, since the displacement portion 24 is displaceable relative to the movable housing 40, it is difficult for the movable housing 40 to restrict the deformation of the elastic deformation portions 24e, 24f. Therefore, the displacement portion 24 further includes a deformation limiting portion 24g that abuts against the elastic deformation portions 24e, 24f when the elastic deformation portions 24e, 24f are deformed, thereby limiting the amount of deformation of the elastic deformation portions 24e, 24f. Therefore, the deformation limiting portion 24g limits excessive deformation of the elastic deformation portions 24e, 24f, preventing the elastic deformation portions 24e, 24f from undergoing plastic deformation. Furthermore, because the deformation limiting portion 24g limits excessive deformation of the elastic deformation portions 24e, 24f (particularly the contact piece base portion 24e), a decrease in contact pressure with the connection object 80 is prevented, and the contact pressure is stabilized.

[0100] In this embodiment, the second side plate 24b is formed with a limiting hole 24g, and the tip of the contact piece base 24e is disposed in the limiting hole 24g, thereby limiting the deformation amount of the contact piece base 24e. This realizes the deformation limiting portion 24g, which limits the deformation amount of the elastic deformation portions 24e, 24f, with a simple configuration.

[0101] 6, in the present embodiment, the contact piece base 24e extends from the first side plate 24a, and the contact piece 24f extends from the contact piece base 24e, and the end 24a1 on the other side in the X direction of the first side plate 24a is located on one side in the X direction of the end 24b1 on the other side in the X direction of the second side plate 24b. Therefore, when the displacement portion 24 is produced by cutting and bending a plate material, the width dimension of the contact piece 24f can be increased. Furthermore, both the end 24a1 of the first side plate 24a on the other side in the X direction and the end 24b1 of the second side plate 24b on the other side in the X direction are configured to be able to abut against the movable-side limiting portions 42, 43 (specifically, the first abutment wall 42). Therefore, the abutment of the movable-side limiting portions 42, 43 against the displacement portion 24 prevents the posture of the displacement portion 24 from being distorted.

[0102] However, in a case where the portion of the terminal 20 extending from the displacement portion 24 extends, for example, parallel to the connection axis AX (see Figure 13) of the connection object 80, there is a risk that the portion may collide with the tip of the connection object 80 when the displacement portion 24 is displaced. Therefore, in this embodiment, the terminal 20 has the avoidance portion 23e (inclined portion 23e) extending from the displacement portion 24, which is the avoidance portion 23e extending in a direction away from the connection axis AX of the connection object 80. This prevents the above-mentioned collision. The structure of the avoidance portion extending in a direction away from the connection axis AX of the connection object 80 is not limited to the structure of the avoidance portion 23e of this embodiment (a structure extending diagonally downward and rearward from the displacement portion 24). For example, the avoidance portion may have a structure that first extends rearward from the displacement portion 24 and then extends downward via a curved portion (a structure that forms a so-called crank shape together with the second front portion 23d).

[0103] Furthermore, in this embodiment, since the displacement portion 24 is displaceable relative to the movable housing 40, the movable housing 40 cannot be properly supported by the displacement portion 24. Therefore, in this embodiment, the movable housing 40 is supported by contacting the support member 30 (fixed housing 30) which does not displace relative to the attachment object 90. Therefore, the movable housing 40 can be supported appropriately.

[0104] In this embodiment, the support member 30 (fixed housing 30) is in a state where the movable housing 40 is sandwiched between the pair of clamping portions 38. This prevents the movable housing 40 from rattling relative to the support member 30. The pair of clamping portions 38 may be structured so that one of them elastically presses into contact with the movable housing 40, and the other receives the pressed movable housing 40. Alternatively, the pair of clamping portions may be formed on the movable housing, and the movable housing may clamp a support member (for example, a fixed housing).

[0105] 〔supplementary explanation〕 It should be noted that the present disclosure is not limited to the above-described embodiment, but the following will provide additional information.

[0106] In the above embodiment, an example has been described in which the movable housing 40 has a structure (X-direction inclined surface 45a) that displaces the movable housing in accordance with a positional deviation of the connection object 80. However, the movable housing of the present disclosure is not limited to this, and does not necessarily have to have such a structure.

[0107] Furthermore, in the above embodiment, an example has been described in which the connector 10 includes the fixed housing 30, but the connector of the present disclosure is not limited to this.

[0108] Furthermore, in the above embodiment, an example was described in which the movable housing 40 is displaceable in the X direction, which is one of the directions perpendicular to the connection direction, but is not displaceable in the Y direction, which is one of the directions perpendicular to the connection direction. However, the movable housing of the present disclosure is not limited to this. The movable housing of the present disclosure may be displaceable in both the X direction and the Y direction. In this case, the movable housing may have a movable-side limiting portion in the Y direction. The movable-side limiting portion in the Y direction refers to a portion configured to abut against the displacement portion when the movable housing is displaced in the Y direction, thereby limiting the position of the displacement portion in the Y direction relative to the movable housing within a predetermined range. Furthermore, in the above embodiment, an example has been described in which the direction perpendicular to the connection direction in which the movable housing 40 can be displaced (X direction) is the direction perpendicular to the terminal arrangement direction, and the direction perpendicular to the connection direction in which the movable housing 40 cannot be displaced (Y direction) is the terminal arrangement direction, but the present disclosure is not limited to this. The direction perpendicular to the connection direction in which the movable housing 40 can be displaced (X direction) may be the terminal arrangement direction, and the direction perpendicular to the connection direction in which the movable housing 40 cannot be displaced (Y direction) may be the direction perpendicular to the terminal arrangement direction. In other words, in the above embodiment, an example has been described in which the "X direction" is the direction perpendicular to the terminal arrangement direction, but the "X direction" in the present disclosure may be the terminal arrangement direction.

[0109] In the above embodiment, an example has been described in which the connector 10 includes a plurality of mounting brackets 50. However, the connector of the present disclosure is not limited to this, and does not necessarily need to include mounting brackets.

[0110] In the above embodiment, the connector 10 is described in which the connection object 80 is connected from above (in the +Z direction) to the mounting surface of the substrate 90 as the attachment object. However, the connector of the present disclosure is not limited to this, and the connection object may be connected from a direction parallel to the mounting surface of the substrate, or may be connected from below to the mounting surface of the substrate.

[0111] In the above embodiment, an example has been described in which the movable housing 40 has the movable-side limiting portions 42 and 43. However, the movable housing of the present disclosure is not limited to this, and may not have any movable-side limiting portions. Even if the movable housing does not have a movable-side limiting portion, the fact that the movable housing is displaceable has the following practical benefits: Since the movable housing having the insertion opening formed therein is displaceable, it is possible to accommodate misalignment of the object to be connected without having to enlarge the insertion opening and thereby impairing dustproofness.

[0112] In the above embodiment, an example has been described in which one terminal 20 electrically connecting an attachment object and a connection object is composed of a single member integrally formed from a conductive material. However, the terminal of the present disclosure is not limited to this, and may be composed of a combination of two or more members. In this case, the terminal does not need to have an intermediate deformation portion.

[0113] In the above embodiment, the terminal 20 is described in which the displacement of the displacement portion 24 is achieved by the deformation of the intermediate deformation portion 23. However, the terminal of the present disclosure is not limited to this. For example, if the terminal is configured by combining two or more members, the displacement of the displacement portion can be achieved even if the terminal does not have an intermediate deformation portion.

[0114] In the above embodiment, an example has been described in which the connecting plate 24c connects the rear ends of the first side plate 24a and the second side plate 24b (i.e., an example in which the "one side in the X direction" of the seventh aspect is the -X direction). However, the connecting plate of the present disclosure is not limited to this, and may connect the front ends of the first side plate and the second side plate. In other words, the "one side in the X direction" may be the +X direction. Even in the above case, as in the above embodiment, the avoidance part may extend from the connecting plate of the displacement part. In this case, the avoidance part may be configured to extend diagonally downward (-Z direction) and forward (+X direction, i.e., to one side in the X direction).

[0115] In the above embodiment, it has been explained that the displacement portion 24 is basically not in contact with the arrangement bottom surface 35a when the connector 10 and the mating terminal 80 are connected. However, the displacement portion 24 may be in contact with the arrangement bottom surface 35a when the connector 10 and the mating terminal 80 are connected. This is because even in such a state, the effect of suppressing repeated sliding between the contact portion and the connection object can be obtained to a certain extent. [Explanation of symbols]
