Abstract

An object of the present invention is to reduce the influence of a movable connector in which a movable housing is displaced on fluctuations in the size of a movable gap in which the movable housing is displaced. A fixed housing 3 has a top wall 3a (first restricting portion) that abuts the movable housing 4 in the direction in which the mating terminal 2a is removed, and a fixed housing 3 that contacts the movable housing 4 in the insertion direction of the mating terminal 2a. And a bottom wall 3b (second restricting portion) in contact therewith. Since the top wall 3a and the bottom wall 3b are both part of the molded body of the fixed housing 3, the distance between them does not vary depending on the mounting effect due to the amount of solder when the fixed housing 3 is fixed to the substrate. That is, the variation in the displacement amount of the movable housing 4 can be kept within the tolerance range of the fixed housing 3 and the movable housing 4. [Selection] Figure 11

Description

  The present invention relates to a connector that is mounted on a substrate and is in electrical contact with a connection object.

  A connector having a movable part on the terminal so that the terminal of the connector can be surely brought into conductive contact with the connection object even if the connection object is misaligned when the connection object is fitted to the connector. Is used. This movable part is arrange | positioned between the board | substrate connection part mounted in a board | substrate in a terminal, and the contact part which carries out electrical contact with the connection target object. When a displacement occurs in the insertion state of the connection object when the connector is fitted, the movable portion is elastically deformed to absorb the displacement, and the contact portion and the connection object can be brought into conductive contact.

  Such connectors include, for example, a fixed housing that is fixed to a terminal board connection portion of a terminal, and a movable housing that is locked in a state of being relatively displaceable with respect to the fixed housing and that holds a contact portion of the terminal. is there. If a displacement occurs when the connection object is fitted, the movable part is elastically deformed, so that the movable housing is relatively displaced with respect to the fixed housing, and the contact part follows the connection object and continues to be in conductive contact. Yes (see Patent Document 1).

  Further, a connector is proposed in which the displacement of the movable housing in the insertion direction of the connection object is regulated by the substrate, and the displacement of the movable housing in the removal direction of the connection object is regulated by contact with the fixed housing (patent) Reference 1, FIG. 2). In such a connector, a first movable gap is formed between the movable housing and the substrate, a second movable gap is formed between the movable housing and the fixed housing, and the movable housing is disposed inside each movable gap. It can be elastically displaced to maintain the conductive contact between the contact portion and the connection object. The first movable gap is held so that the movable housing is lifted from the substrate and floats by a terminal in which a substrate connecting portion provided at one end is mounted on the substrate and the other end is held by the movable housing. It is formed by that. The second movable gap is formed by disposing the fixed housing on the upper side (the side away from the substrate) with respect to the movable housing.

JP2012-129109A

  By the way, the size of the first movable gap varies depending on the amount of solder used when the connector is mounted on the board, the degree of warpage of the board, and the like. Further, it varies depending on differences in assembly accuracy, such as the depth of press-fitting of terminals with respect to the fixed housing and the movable housing, and the fixed position. As described above, the first movable gap and the second movable gap largely fluctuate not only due to the tolerances of individual parts constituting various connectors but also due to the effects related to the assembly of components and the mounting on the board. Therefore, in order to sufficiently secure the first movable gap and the second movable gap while assuming such a fluctuation amount, it is necessary to provide each movable gap in advance.

  However, if each movable gap is increased, the maximum elastic deformation amount of the movable part increases, so that when the movable housing is greatly displaced due to the insertion force of the connection object when the connection object is fitted, a large burden is placed on the movable part. It takes. As a result, there are problems such as the movable part being easily plastically deformed and easily damaged. Further, there is a disadvantage that the entire connector is enlarged by providing a large movable gap.

  The present invention has been made against the background of the prior art as described above. The purpose is to reduce the influence of the connector in which the movable housing is displaced on the variation in the size of the movable gap in which the movable housing is displaced.

  In order to achieve the above object, the present invention is configured as follows.

  The present invention includes a fixed housing fixed to a substrate, a movable housing which is held so as to be displaceable with respect to the fixed housing and has an insertion port for a connection object, and a contact portion with the connection object. In the connector including one terminal side held by the fixed housing and the other end side held by the movable housing, the fixed housing abuts against the movable housing in the removal direction of the connection object. And a second restricting portion that contacts the movable housing in the insertion direction of the connection object.

  Both the first restricting portion and the second restricting portion are integrally provided as a configuration of the fixed housing. Therefore, the distance between the first restricting portion and the second restricting portion does not vary depending on the mounting effect due to the amount of solder when the fixed housing is fixed to the substrate, and is constant. That is, the variation in the displacement amount of the movable housing remains within the tolerance range of the fixed housing and the movable housing. For this reason, unlike the prior art, it is not necessary to set the movable gap large in advance. As a result, even if the movable housing is displaced due to the insertion force of the connection object, even if the movable portion of the terminal is repeatedly elastically deformed, it is possible to suppress a situation in which the elastic deformation greatly causes plastic deformation or damage. it can. In addition, since it is not necessary to set a large movable gap, the connector can be made smaller than the prior art while ensuring the necessary movable gap.

  As described above, when the fixed housing and the movable housing have a structure that can contact in the insertion direction and the removal direction of the connection object, it is difficult to dispose the movable housing inside the fixed housing in the insertion direction. A method is conceivable in which the movable housing is disposed inside by integrally cutting the fixed housing and the movable housing and then cutting off the connecting portion between the fixed housing and the movable housing. However, in this method, the mold structure is very complicated, and it is difficult to cut the connecting portion. In this respect, in the present invention, as described later, the fixed housing has a horizontal cylindrical shape in which the cylindrical axis direction intersects the insertion direction and the extraction direction, and the fixed housing has a configuration having an insertion opening. Even when the fixed housing and the movable housing are in contact with each other in the insertion / extraction direction, the movable housing can be arranged inside the fixed housing.

  The fixed housing has a horizontal cylindrical shape, and may have a storage chamber for the movable housing therein.

  According to this, the movable housing is displaced in the insertion / removal direction by housing the movable housing in the housing chamber of the horizontal cylindrical fixed housing, and the horizontal cylindrical wall body of the fixed housing covers the periphery of the movable housing. Can be brought into contact with the fixed housing. Thereby, the displacement of a movable housing can be suppressed reliably.

  The first restricting portion is a top wall of the fixed housing facing the top surface of the movable housing, and the second restricting portion has an inner surface facing the bottom surface of the movable housing and an outer surface facing the substrate. It can be the bottom wall of the stationary housing.

  According to this, the top surface of the movable housing can be brought into contact with the top wall of the fixed housing, and the bottom surface of the movable housing can be brought into contact with the bottom wall of the fixed housing. Thereby, the displacement of the movable housing in the insertion / extraction direction can be easily and reliably suppressed. The movable housing is displaced between the top wall and the bottom wall of the fixed housing. For this reason, it is possible to set the movable gap of the movable housing considering only the tolerance of the fixed housing and the movable housing, and it is not necessary to consider the influence of other component tolerances, assembly, and mounting on the setting of the movable gap. Also good.

  The fixed housing has an insertion opening for the movable housing.

  Accordingly, the movable housing can be easily inserted into the fixed housing through the insertion opening. Further, when the fixed housing is in the shape of a horizontal cylinder as described above, at least one side end of the fixed housing can be used as the insertion opening. According to this, the movable housing can be easily inserted from the insertion opening along the cylinder axis direction of the fixed housing. For example, by providing a retaining wall at the other end, it is possible to prevent the movable housing from falling off the fixed housing when assembling the connector, and it is movable by the retaining wall. It is also possible to protect the housing. The insertion opening may be provided not only at one end but also at the other end. According to this, the movable housing can be inserted without worrying about restrictions on the insertion direction.

  In the movable part of the present invention, the load that elastically deforms in at least one of the insertion direction and the removal direction of the connection object to the fixed housing is a normal contact between the contact part and at least one of the connection objects. The load can be smaller than the load displaced in the insertion / extraction direction from the position.

  By carrying out like this, when a connection target object displaces with respect to a contact part in the insertion / extraction direction or the extraction direction, a movable part elastically deforms before position-shifting with respect to a contact part. Therefore, since the contact part of a terminal does not shift | deviate with respect to a connection target object by fine sliding, generation | occurrence | production of the peeling of a plating of a connection target object can be suppressed, Therefore Connection reliability can be maintained.

  According to the connector of the present invention, the influence factor for the size of the movable gap in which the movable housing is displaced can be kept within the tolerance between the fixed housing and the movable housing, and the influence factor can be reduced as compared with the prior art. Therefore, the connector of the present invention can be made a connector having excellent durability because it is difficult to cause plastic deformation or damage even if the movable part is repeatedly elastically deformed. Further, the influencing factor for the movable gap is the tolerance between the fixed housing and the movable housing, and it is not necessary to provide a large movable gap in advance in consideration of other influencing factors. In this respect, the entire connector can be made smaller than the prior art, and the occupied area of the board and the occupied space on the board can be reduced.

  Hereinafter, an embodiment of a connector of the present invention will be described with reference to the drawings.

In the present specification, claims, and drawings, the width direction along the arrangement direction of the terminals 5 of the connector 1 is the X direction, the front-rear direction is the Y direction, and the height direction is the Z direction. Further, the plane side in the height direction Z is referred to as “upper side”, and the bottom side is referred to as “lower side”. Such specification of the vertical direction does not limit the mounting direction and usage direction of the connector of the present invention.
In addition, about the connector 1, since a rear view is represented as the same thing as a front view, description is abbreviate | omitted. Moreover, since the left side view is represented as being bilaterally symmetrical with the right side view, the description is omitted.

First Embodiment [FIGS. 1 to 12]:
The connector 1 is mounted on the substrate C, and conducts and connects the substrate pattern of the substrate C and the mating connector 2 as a “connection object”. As shown in FIGS. 1 to 6, the connector 1 includes a fixed housing 3, a movable housing 4, a plurality of terminals 5, and two fixed members 6.

[Fixed housing]
The fixed housing 3 is formed of a molded body of insulating resin, and is formed as a horizontal cylindrical shape or a substantially rectangular parallelepiped tunnel shape. 1 to 6, the fixed housing 3 includes a top wall 3a, a bottom wall 3b, a front wall 3c, a back wall 3d, a housing chamber 3e of the movable housing 4, and an integral resin molded body. Have

  The top wall 3a has an XY plane and has a plurality of insertion ports 3a1 through which the mating terminals 2a of the mating connector 2 are inserted. A plurality of insertion ports 3a1 are arranged in parallel along the width direction X, and two rows of the insertion ports 3a1 are provided along the front-rear direction Y. A lead-in portion 3a2 for inserting the terminal 5 of the mating connector 2 is provided above the insertion port 3a1. In addition, the top wall 3a is formed shorter in the width direction X than the bottom wall 3b. As a result, an insertion opening 3e1 to be described later becomes large, so that the movable housing 4 can be easily inserted into the accommodation chamber 3e.

  The bottom wall 3b is disposed to face the top wall 3a via the storage chamber 3e. At the center of the bottom wall 3b, there is a terminal insertion portion 3b1 for inserting the terminal 5. The terminal insertion portion 3b1 is sized to allow all the terminals 5 to be inserted, and the bottom wall 3b is formed at a position where the movable housing 4 can be supported from the bottom surface side. Specifically, the length of the terminal insertion portion 3 b 1 in the width direction X is shorter than the length of the movable housing 4 in the width direction X. Therefore, the movable housing 4 is supported by the protrusions 4d disposed on both ends in the width direction X of the movable housing 4 being disposed on the bottom wall 3b. A fixing hole 3b2 for fixing a fixing member 6 to be described later is formed on each of both end sides in the width direction X of the bottom wall 3b.

  The front wall 3c and the back wall 3d are arranged to face each other with the movable housing 4 interposed therebetween, and are connected to the top wall 3a and the bottom wall 3b. Fixing grooves 3c1 and 3d1 for press-fitting a housing fixing portion 5b of a terminal 5 described later are formed below the front wall 3c and the back wall 3d.

  The storage chamber 3e is formed by a top wall 3a, a bottom wall 3b, a front wall 3c, and a back wall 3d. Further, at both ends in the width direction X, insertion openings 3e1 for inserting the movable housing 4 into the storage chamber 3e are formed.

[Movable housing]
The movable housing 4 is a molded body of an insulating resin and is formed in a substantially rectangular parallelepiped shape. The movable housing 4 includes an insertion port 4a1 provided in the top surface 4a, a fitting chamber 4b, a terminal insertion portion 4c, and a protruding portion 4d.

  The top surface 4 a forms the upper surface of the movable housing 4. A plurality of insertion openings 4a1 are provided in parallel on the top surface 4a. In particular, in the present embodiment, two rows of the insertion ports 4 a 1 along the width direction X are formed along the front-rear direction Y corresponding to the insertion ports 3 a 1 of the fixed housing 3. Each insertion port 4a1 and the insertion port 3a1 of the fixed housing 3 are disposed along the height direction Z in a state in which the movable housing 4 is disposed at the regular storage position P2 in the storage chamber 3e of the fixed housing 3.

  The fitting chamber 4b is formed in the movable housing 4 so as to communicate with the insertion port 4a1, and the contact portion 5e of the terminal 5 and the mating terminal 2a of the mating connector 2 are in conductive contact within the mating chamber 4b. .

  The terminal insertion portion 4 c is provided at the lower end of the movable housing 4 so as to communicate with the fitting chamber 4 b. A contact portion 5e of the terminal 5 described later is inserted into the fitting chamber 4b from the terminal insertion portion 4c.

  The protrusions 4d are formed on the lower side of the movable housing 4 so as to protrude toward both ends in the width direction X and both ends in the front-rear direction Y.

(Terminal)
The terminal 5 is formed by punching a conductive metal plate and bending it. As shown in FIG. 7, the terminal 5 includes a substrate connecting portion 5a, a housing fixing portion 5b, a movable portion 5c, a base end portion 5d, and a contact portion 5e.

  The board connecting part 5 a is disposed on one end side of the terminal 5. The terminal 5 is connected to a circuit contact (not shown) of the substrate C by soldering the substrate connecting portion 5a to the substrate C.

  The housing fixing portion 5b is connected to the board connecting portion 5a, and projecting portions 5b1 that are engaged with and fixed to the fixing housing 3 are formed on both ends in the width direction X.

  The movable portion 5c is a thin-shaft spring piece that is connected to the housing fixing portion 5b and has a substantially inverted U shape. The movable portion 5c can be elastically deformed in any of the width direction X, the front-rear direction Y, and the height direction Z.

  The base end portion 5d is connected to the movable portion 5c and extends along the height direction Z. On both ends of the base end portion 5d in the width direction X, projecting portions 5d1 that engage with the inner wall of the fitting chamber 4b of the movable housing 4 are formed. As a result, the base end portion 5 d is fixed to the movable housing 4.

  The contact portion 5e is connected to the base end portion 5d, and includes an elastic arm 5e1 and a contact portion 5e2 elastically supported on the distal end side of the elastic arm 5e1. Particularly in the present embodiment, the contact portion 5e has two elastic arms 5e1 and two contact portions 5e2. The two contact portions 5e2 are in conductive contact with the mating terminal 2a of the mating connector 2 so as to be sandwiched from both sides in the front-rear direction Y.

[Fixing member]
The fixing member 6 is a metal piece obtained by punching a flat metal plate, and is fixed one by one to the fixing holes 3b2 provided on both end sides in the width direction X of the bottom wall 3b. The fixing member 6 includes a substrate fixing portion 6a that is soldered to the substrate C, and a regulation plate 6b that protrudes from the upper surface of the bottom wall 3b. Two substrate fixing portions 6a are provided along the front-rear direction Y.

[Description of assembly method]
As shown in FIG. 8, the movable housing 4 is inserted into the accommodation chamber 3 e from the insertion opening 3 e 1 of the fixed housing 3. At that time, one fixing member 6 may be fixed to the fixed housing 3 in advance. Thereafter, the other fixing member 6 is fixed to the fixed housing 3 in a state where the movable housing 4 is inserted into the accommodation chamber 3e. Thereby, dropping of the movable housing 4 from the fixed housing 3 can be prevented.

  Subsequently, the terminal 5 is fixed to the movable housing 4. First, a jig (not shown) is inserted from the insertion opening 3 e 1 between the lower surface 3 a 3 of the top wall 3 a of the fixed housing 3 and the top surface 4 a of the movable housing 4. This jig is for restricting the displacement of the movable housing 4 when the terminal 5 is fixed to the movable housing 4. Next, as shown in FIG. 9, the contact portion 5 e of the terminal 5 is inserted from the terminal insertion portion 3 b 1 provided on the bottom wall 3 b of the fixed housing 3 and the terminal insertion portion 4 c provided on the bottom surface side of the movable housing 4. And the base part 5d is fixed inside the fitting chamber 4b by making the protrusion 5d1 provided in the base end part 5d engage with the inner wall of the fitting chamber 4b. Thus, when the contact portion 5e and the base end portion 5d are inserted into the fitting chamber 4b, the movable housing 4 tends to be displaced upward by the insertion force of the base end portion 5d, but the top surface 4a is not shown. , The upward displacement is regulated, and the base end portion 5d is directly press-fitted into the fitting chamber 4b. Thus, the fixing of the contact portion 5e and the base end portion 5d of the terminal 5 to the movable housing 4 is completed.

  As described above, the top surface 4a of the movable housing 4 is in contact with the lower surface 3a3 of the top surface wall 3a of the fixed housing 3 through the jig uniformly over the length direction. For this reason, it is possible to make the insertion amount of the base end portion 5 d of each terminal 5 into the fitting chamber 4 b uniform over the longitudinal direction of the movable housing 4. That is, as a connector of the prior art, there is known a connector having protrusions protruding laterally at both end portions in the longitudinal direction of the movable housing. In this connector, the protrusion is brought into contact with the fixed housing to stop the displacement of the movable housing. However, as the length of the movable housing increases, the fixed housing and the protrusions at both ends contacting the fixed housing The central part of the housing that is not in contact may be warped. When the base end portion 5d of the terminal 5 is inserted from the bottom surface side, the insertion amount is appropriate at both end sides of the movable housing, but the insertion amount becomes shorter toward the center portion that is warped from there. Thus, if the amount of insertion is not uniform for each terminal 5 in the initial state of assembly, a load is applied to the movable portion 5c from the beginning, and fatigue durability is inferior. However, in the connector 1 of the present embodiment, as described above, the top surface 4a of the movable housing 4 is brought into contact with the above-described jig (not shown) over the length direction, so that the terminal is not assembled. Even if 5 is press-fitted, the movable housing 4 does not warp. Therefore, the base end portion 5d of each terminal 5 can be uniformly inserted into the fitting chamber 4b in the initial state of assembly, so that the fatigue durability of the terminal 5 is not impaired.

  Further, in order to prevent the movable housing 4 from warping when the mating terminal 2 a is removed, the top surface 4 a of the movable housing 4 is not necessarily in contact with the bottom surface 3 a 3 of the top wall 3 a of the fixed housing 3. Instead, it is also possible to discretely provide contact portions that contact the top surface 4a at a plurality of locations in the longitudinal direction including both end sides and the central portion.

  Thereafter, the housing fixing portion 5b of the terminal 5 is press-fitted into the fixing grooves 3c1 and 3d1 of the front wall 3c and the rear wall 3d of the fixed housing 3 and fixed. In this way, the fixing of the housing fixing portion 5b of the terminal 5 to the fixed housing 3 is completed. Thus, the assembly of the connector 1 is completed.

[Explanation of usage]
The mating terminal 2 a of the mating connector 2 is inserted from the insertion port 3 a 1 of the fixed housing 3. The mating terminal 2a is inserted into the fitting chamber 4b from the insertion port 4a1 of the movable housing 4 as it is, and is brought into contact with the contact portion 5e of the terminal 5. The mating terminal 2a widens the gap between the contact portions 5e2. At this time, the movable portion 5c is elastically deformed by the pressing of the mating terminal 2a against the contact portion 5e, so that the movable housing 4 becomes the bottom wall 3b of the fixed housing 3. Displacement toward In a state where the movable housing 4 is in contact with the bottom wall 3b and the downward movement is restricted, the mating terminal 2a further widens the gap between the contact portions 5e2, and the mating terminal 2a is inserted therebetween. At that time, the contact portion 5e2 and the counterpart terminal 2a are displaced from each other. Thereafter, the insertion of the mating terminal 2a into the mating chamber 4b is stopped, and the mating operation is completed in a state where the mating terminal 2a is in conductive contact with the contact portion 5e2 of the terminal 5 at the regular contact position P1 (FIG. 10, see FIG.

  The movable housing 4 is accommodated in the accommodating chamber 3e, and the displacement along the width direction X is restricted by the two restricting plates 6b. However, the interval between the two regulating plates 6b is longer than the length along the width direction X of the movable housing 4, and a movable gap S1 is formed between the movable housing 4 (see FIGS. 10 and 12). Therefore, the movable housing 4 can be displaced along the width direction X by the length of the movable gap S1 within the accommodation chamber 3e. Therefore, when a displacement occurs when the board C is fitted in the direction along the width direction X, the movable portion 5c of the terminal 5 is elastically deformed in the width direction X, so that the movable housing 4 is movable with respect to the fixed housing 3. The inside of S1 is elastically displaced in the width direction X.

  Further, the displacement along the front-rear direction Y is regulated by the front wall 3c and the back wall 3d of the fixed housing 3 while the movable housing 4 is housed in the housing chamber 3e. However, the distance L1 between the front wall 3c and the back wall 3d is longer than the length in the front-rear direction Y of the movable housing 4 (particularly the length of the protruding portion 4d in the present embodiment). S2 is formed (see FIGS. 11 and 12). Therefore, the movable housing 4 can be displaced along the front-rear direction Y by the length of the movable gap S2 in the accommodation chamber 3e. Therefore, when a displacement occurs when the board C is fitted in the direction along the front-rear direction Y, the movable portion 5 c of the terminal 5 is elastically deformed in the front-rear direction Y, so that the movable housing 4 is movable with respect to the fixed housing 3. The inside of S2 is elastically deformed in the front-rear direction Y.

  Further, in a state where the movable housing 4 is accommodated in the accommodating chamber 3e, the displacement along the height direction Z, that is, the insertion direction in which the mating terminal 2a of the mating connector 2 is inserted into the connector 1 toward the board C, The displacement in the removal direction in which a certain mating terminal 2a is removed from the connector 1 so as to be away from the board C is regulated by the top wall 3a and the bottom wall 3b. However, the distance L2 between the top wall 3a and the bottom wall 3b is longer than the length of the movable housing 4 in the height direction Z, and a second movable gap S4 is provided between the movable housing 4 and the top wall 3a. A first movable gap S3 is provided between the movable housing 4 and the bottom wall 3b (see FIG. 11). Therefore, the movable housing 4 can be displaced along the height direction Z by the total length of the first movable gap S3 and the second movable gap S4 in the accommodation chamber 3e. For this reason, when the substrate C is displaced in the height direction Z, the movable portion 5c of the terminal 5 is elastically deformed in the height direction Z, so that the movable housing 4 has the movable gaps S3 and S4 with respect to the fixed housing 3. The inside is elastically deformed in the height direction Z.

  Since the top wall 3a and the bottom wall 3b are provided as a part of the fixed housing 3 formed of a single insulating resin molding, the interval L2 along the height direction Z is constant within a tolerance range. Therefore, the total length of the first movable gap S3 and the second movable gap S4 is, for example, the amount of solder used when the fixed housing 3 is soldered to the substrate C, the warpage of the substrate C, the fixed housing. 3 does not fluctuate depending on the amount of press-fitting of the terminal 5 into the fitting groove 4b of the movable housing 4 or the fixed position. Therefore, since the maximum elastic displacement amount in the height direction Z of the movable housing 4 in the accommodation chamber 3e can be easily controlled, the movable housing 4 is moved in the height direction with respect to the fixed housing 3 on the assumption of such fluctuation. It is not necessary to provide a large space between the top wall 3a and the bottom wall 3b in advance so that it can be sufficiently elastically deformed along Z. Therefore, it is possible to make it difficult to cause a situation in which the movable portion 5c is elastically deformed excessively repeatedly and the movable portion 5c is plastically deformed or damaged. Further, the influential factor for the first movable gap S3 and the second movable gap S4 is the tolerance between the fixed housing and the movable housing, and it is not necessary to provide a large gap between the top wall 3a and the bottom wall 3b. Can be reduced, and the occupied area of the substrate C and the occupied space on the substrate C can be reduced as compared with the conventional case.

  Moreover, the fixed housing 3 of this embodiment is a horizontal cylinder shape or a tunnel shape, and accommodates the movable housing 4 in the accommodation chamber 3e. Therefore, the distance L1 along the front-rear direction Y between the front wall 3c and the back wall 3d is also constant within a tolerance range. Therefore, the situation that the length of the movable gap S2 varies depending on the fixed position of the terminal 5 to the fixed housing 3 or the movable housing 4 as described above does not occur. Therefore, since the maximum elastic displacement amount in the front-rear direction Y of the movable housing 4 in the accommodation chamber 3e can be easily controlled, the movable part 5c is elastically deformed excessively and repeatedly, so that the movable part 5c is plastically deformed. It can be made difficult to cause damage or damage.

  Further, for the movable portion 5c of the terminal 5, a load that elastically deforms the mating terminal 2a of the mating connector 2 in the insertion direction and the withdrawal direction (the height direction Z in the present embodiment) of the mating connector 2 is applied to the contact portion 5e and the mating terminal 2a. Is set smaller than the load that is displaced in the insertion / extraction direction from the normal contact position P1. Therefore, when the mating terminal 2a is displaced with respect to the contact portion 5e in the insertion / extraction direction or the removal direction, the movable portion 5c is elastically deformed before being displaced with respect to the contact portion 5e. Therefore, the contact portion 5e can be reliably kept in conductive contact at the regular contact position P1 without being slightly displaced with the counterpart terminal 2a. Therefore, even if the connector 1 is displaced along the insertion / extraction direction of the mating terminal 2a, the occurrence of peeling of the plating of the contact portion 5e of the terminal 5 can be suppressed. Therefore, the connector 1 with high connection reliability can be obtained.

Variations:
In the present embodiment, the fixed housing 3 has a tunnel shape, and the top wall 3 a covers the top surface 4 a of the movable housing 4. On the other hand, other shapes may be used as long as the top wall 3a can regulate the displacement of the movable housing 4 in the removal direction in the insertion / extraction direction as the “first restriction portion”. For example, the top wall 3 a is provided so as to be biased to only one end in the front-rear direction Y or only one end in the width direction X and covers only a part of the top surface 4 a of the movable housing 4. It may be.

  In the present embodiment, the top wall 3a provided above the movable housing 4 as the “first restricting portion”, and the bottom wall provided below the movable housing 4 as the “second restricting portion”. An example with 3b was shown. On the other hand, for example, a locking portion configured to sandwich a structure that protrudes outward in the width direction X or outward in the front-rear direction Y, such as the protruding portion 4 d of the movable housing 4, is referred to as “first restriction”. Part "or" second restricting part ". Such a configuration can also restrict the displacement of the movable housing 4 in the direction in which the mating connector 2 is removed or inserted.

  In this embodiment, the example which has the insertion opening part 3e1 in the both ends in the width direction X of the storage chamber 3e which the fixed housing 3 has was shown. On the other hand, it is good also as a structure which has the insertion opening part 3e1 only in any one, and the other is obstruct | occluded by the wall body for prevention, and the movable housing 4 cannot be inserted. Such a retaining wall may be a part integrally formed with the fixed housing 3 or may be attached to the fixed housing 3 as a separate part. Thereby, the displacement of the movable housing 4 to the side where the retaining wall is formed in the width direction X can be reliably regulated by the retaining wall. Further, it is possible to make it difficult for the movable housing 4 to fall off the fixed housing 3 when the connector 1 is assembled.
