Description

Description Title of the invention: CONNECTOR technical field The present invention relates to a connector capable of detecting a connection state with a homologous connector. TECHNOLOGICAL BACKGROUND Patent document 1 discloses a connector in which a plate-shaped terminal fitting, which can be connected to a device such as an inverter, is housed in a casing. Such a connector is generally called a high-voltage connector. Patent Document 1: JP2020-187918A SUMMARY OF THE INVENTION A connector such as the prior art high-voltage connector described above can be designed to detect a connection state between the connector and a safety-compliant or analogous peer connector. For example, a small U-shaped terminal fitting (called a short terminal) is integrated into the housing, and the short terminal is brought into contact with a pair of electrodes in the peer connector at the moment of connection to form a short circuit, so that the connection state can be detected. However, when excessive positional deviation occurs between the short terminal and the peer connector electrodes due to a manufacturing tolerance or similar characteristic of the connector, it may become difficult to connect the short terminal to the peer connector electrodes even if the connection itself is made properly. One purpose of this disclosure is to provide a connector in which a short terminal can be easily aligned. This disclosure provides a connector comprising: a terminal fitting; an electrical wire connected to the terminal fitting; a first housing in which the terminal fitting is stored, the first housing forming a connection portion with a corresponding connector; a sealing element arranged to surround an outer perimeter of the first housing; a front support mounted on the first housing to prevent the sealing element from protruding from the first housing; and a second housing comprising a short terminal, the short terminal being configured to detect a connection state with the corresponding connector, wherein the second housing is fixed to the first housing and retained by the front support in a state where the second housing is movable in a direction intersecting a connection direction with the corresponding connector in a position where the The short terminal faces the corresponding connector. This disclosure is briefly described as above. Further details of this disclosure will be clarified by examining an embodiment of the present invention described below with reference to the accompanying drawings.

DESCRIPTION OF IMPLEMENTATION METHODS <Mode de réalisation> In the following, a connector 1 according to an embodiment of this disclosure will be described with reference to the drawings. The connector 1 shown in [Fig. 1] functions as a relay connector that electrically connects a pair of wires 20 of connector 1 and a corresponding connector (not shown) to be connected to connector 1. Connector 1 includes a short terminal 90 (see Figures 1, 3, etc.) configured to detect a connection state with a corresponding connector. A specific function of the short terminal 90 will be described later. In the following, to facilitate description, as shown in [Fig. 1], etc., a "front-to-back direction," a "top-to-bottom direction," and a "width direction" are defined. The "front-to-back direction," the "top-to-bottom direction," and the "width direction" are orthogonal to each other. The front-to-back direction coincides with the interlocking direction of connector 1 and its counterpart connector, and "front" and "back" correspond respectively to a forward and a backward side of the connection between connector 1 and its counterpart connector. As shown in Figures 1 and 2, the connector 1 comprises a pair of terminal fittings 10, a pair of electrical wires 20 connected to the pair of terminal fittings 10, a first housing 30 in which the pair of terminal fittings 10 is stored, and a shielding envelope 40 mounted on the first housing 30 from a On the rear side, a bellows 50 covering the shielding envelope 40 and the pair of electrical wires 20, a trim 60 mounted on the first housing 30 from a front side, a front support 70, and a second housing 80, and a short terminal 90 mounted on the second housing 80. In the following, each element constituting the connector 1 will be described in order. First, the terminal fitting 10 and the electrical wire 20 will be described. The terminal fitting 10 is formed by pressing, bending, and similar processes on a metal plate and has a shape extending in the front-to-back direction. The terminal fitting 10 comprises an elongated, flat, plate-shaped terminal portion 11 (see Figures 1, 2, 8, etc.) extending in the front-to-back direction, and a connecting portion 12 (see [Fig. 8]) located at a rear end portion of the terminal portion 11. An end portion of the electrical wire 20 is connected to the connecting portion 12. As shown in [Fig.8], the electrical wire 20 comprises a central conductor wire 21 made of metal and an insulating sheath 22 covering the central conductor wire 21. At the end of the electrical wire 20, the insulating sheath 22 is removed to expose the central conductor wire 21, and the connection portion 12 of the terminal fitting 10 is crimped and fixed to the exposed central conductor wire 21. Thus, the electrical wire 20 connected to the terminal fitting 10 extends backwards from the connection portion 12 of the terminal fitting 10. Next, the first housing 30 will be described. The first housing 30 is a resin-molded product. As shown in Figures 2, 7, 8, etc., the first housing 30 has a tubular shape extending in the front-to-back direction and an elongated flat shape in its width when viewed from the front-to-back direction. A rim portion 31, projecting radially outward, is formed on the outer periphery of a central portion of the first housing 30 in the front-to-back direction around its entire periphery.A portion of the first housing 30 on the front side of the rim portion 31 constitutes a connecting portion 32 which is inserted into and connected to a corresponding tubular connecting portion (not shown) of the corresponding connector, and a portion of the first housing 30 on the rear side of the rim portion 31 constitutes an insertion portion 33 which is inserted into the shielding envelope 40 (see figures 7 and 8). In the first housing 30, a pair of terminal insertion holes 34, a pair of terminal storage chambers 35, and a pair of trim storage parts 36 are formed in that order from the front side to the rear side at respective pairs of positions arranged at intervals in the width direction so as to communicate with each other in the front-to-rear direction. A front end of the terminal insertion hole 34 opens onto a front end of the first housing 30 (a front end of the connecting part 32), and a rear end of the trim storage part 36 opens onto a rear end of the first housing 30 (a rear end of the insertion part 33). The terminal parts 11 of the terminal fittings 10 are inserted into the terminal insertion holes 34, the connecting parts 12 of the terminal fittings 10 are stored in the terminal storage chambers 35, and trims 93 (see [Fig.8]), which will be described later, covering the outer peripheries of the pair of electrical wires 20, are stored in the trim storage parts 36 (see [Fig.8]). A recessed portion 37, opening forwards and recessed rearwards, is formed in the lower parts of the pair of terminal insertion holes 34 in the connection portion 32 of the first housing 30 (see Figures 7 to 9). A projecting portion 82 (see [Fig. 3] and similar) of the second housing 80, which will be described later, is inserted into the recessed portion 37 (see Figures 7 to 9). Next, the shielding enclosure 40 will be described. As shown in Figures 1, 2, 7 and 8, the metal shielding enclosure 40 has a tubular shape extending in the front-to-back direction so as to be inserted externally into the insertion portion 33 of the first housing 30. The shielding enclosure 40 is mounted onto the insertion portion 33 of the first housing 30 from the rear side, and its function is to prevent the transmission of electromagnetic noise to the pair of electrical wires 20 located inside the first housing 30. Next, the bellows 50 will be described. As shown in Figures 1 and 2, the rubber bellows 50 has a tubular shape extending in the front-to-back direction and comprises a large-diameter portion 51 that covers an outer periphery of the shielding sheath 40, a small-diameter portion 52 that covers the outer peripheries of the pair of electrical wires 20 extending rearward from the shielding sheath 40, and a connecting portion 53 that links the large-diameter portion 51 and the small-diameter portion 52. The bellows 50 serves to protect the pair of electrical wires 20 extending rearward from the shielding sheath 40. The pair of terminal fittings 10, the pair of electrical wires 20, the first housing 30, the shielding envelope 40, and the bellows 50 described above constitute a subassembly 2 (see [Fig.2]), which forms part of the connector 1. The subassembly 2 is assembled according to the following procedure. First, by inserting the end portions of the pair of electrical wires 20 into hollow portions of the bellows 50 and the shielding casing 40 in that order from the rear side, the pair of electrical wires 20 is inserted into the bellows 50 and the shielding casing 40. Then, the pair of electrical wires 20 is inserted through A support 94 (see Figures 7 and 8). A pair of through holes 95 (see [Fig. 8]) is formed in the resin support 94 so as to be spaced apart widthwise. By inserting the end portions of the pair of electrical wires 20 into the pair of through holes 95 from the rear, the pair of electrical wires 20 is inserted through the support 94. Next, each of the pair of electrical wires 20 is inserted through the annular rubber fittings 93 (see [Fig. 8]). Then, the connecting portions 12 of the terminal fittings 10 are crimped and secured to the exposed central conductor wires 21 at the end portions of each of the electrical wires 20. Next, the pair of terminal connectors 10 to which the pair of electrical wires 20 is connected is stored in the first housing 30. Thus, each terminal connector 10 is inserted into the housing 30 from the rear side. As a result, the terminal parts 11 are inserted into the respective terminal insertion holes 34, and the connecting parts 12 are stored in the respective terminal storage chambers 35. In a state in which the terminal connectors 10 are fully inserted, the front parts of the pair of terminal parts 11 protrude forward from the front end of the first housing 30 (the front end of the connecting part 32) (see [Fig. 2]), and the pair of electrical wires 20 extending backward from the pair of terminal connectors 10 extends backward from the rear end of the first housing 30 (the rear end of the insertion part 33).In the state in which the terminal fittings 10 are fully inserted, as shown in [Fig.8], a locking hole 1a provided in the terminal part 11 and a locking projection 34a provided in the terminal insertion hole 34 are engaged with each other, so that the terminal fittings 10 are prevented from coming out towards the rear side from the first housing 30. Next, the pair of trims 93 through which the pair of electrical wires 20 is inserted is moved forward relative to the pair of electrical wires 20 to be stored in the pair of trim storage parts 36 of the first housing 30, and the support 94 through which the pair of electrical wires 20 is inserted is moved forward relative to the pair of electrical wires 20 to be mounted on the rear end of the first housing 30 (the rear end of the insertion part 33). In a state in which the trims 93 are fully stored, the trims 93 are pressed and clamped between the outer peripheral surfaces of the electrical wires 20 and the inner peripheral surfaces of the trim storage parts 36 (see [Fig. 8]), and serve to seal a gap between the electrical wires 20 and the trim storage parts 36.In a state in which the bracket 94 is fully mounted, as shown in [Fig.8], a locking hole 96 is provided in the bracket 94 and a . The locking projection 33a provided on an outer periphery of the insertion part 33 are engaged with each other, so that the support 94 is prevented from falling rearward from the first housing 30. The support 94 is arranged adjacent to the pair of trims 93 on the rear side, so as to prevent the pair of trims 93 from falling rearward from the first housing 30. Next, the shielding sleeve 40, through which the pair of electrical wires 20 is inserted, is mounted on the insertion portion 33 of the first housing 30 from the rear. Therefore, the shielding sleeve 40 is inserted externally into the insertion portion 33 of the first housing 30. In a fully mounted state, as shown in [Fig. 7], a locking piece 41 provided in the shielding sleeve 40 and a locking hole 33b provided in an outer periphery of the insertion portion 33 engage with each other, preventing the shielding sleeve 40 from falling out of the first housing 30. Next, the bellows 50 through which the pair of electrical wires 20 is inserted is moved relatively forward with respect to the pair of electrical wires 20, and the large diameter part 51 of the bellows 50 is mounted on the outer periphery of the shielding envelope 40. As a result, the mounting of the bellows 50 is completed, and the assembly of subassembly 2 is completed, so that subassembly 2 re- shown in [Fig.2] is obtained. Next, the seal 60 will be described. As shown in [Fig. 2], the rubber seal 60, made of rubber, has a tubular shape extending in the front-to-back direction and an elongated flat shape in the width direction, corresponding to an outer peripheral shape of the connecting part 32 of the first housing 30 when viewed from the front-to-back direction. The seal 60 is mounted on an outer periphery of the connecting part 32 of subassembly 2 from the front side (see Figures 1, 7, etc.).In a state where the tubular connecting portion of the corresponding connector is inserted externally into the connecting portion 32 by joining connector 1 and the corresponding connector, the gaskets 60 mounted on the connecting portion 32 are pressed and clamped between an outer peripheral surface of the connecting portion 32 and an inner peripheral surface of the corresponding connecting portion. This ensures a sealing function for a gap between the connecting portion 32 and the corresponding connecting portion. Next, the second housing 80 and the short terminal 90 will be described. The second housing 80 is a resin-molded product and its function is to hold the short terminal 90, which performs a connection state detection function with the corresponding connector. As shown in [Fig. 3], the short terminal 90 includes inte- gralement a base part in the form of a flat plate 91 extending in the front-back and top-down directions, and a pair of terminal parts in the form of a rod 92 extending forward from the upper and lower ends of a front end of the base part 91. As shown in Figures 3 to 5, the second housing 80 comprises a rectangular tubular main body portion 81 extending in the front-to-back direction. The main body portion 81 opens towards the front side, and the rear side is closed by a rear wall (not shown). When the connector 1 and the counterpart connector are connected to each other, a connection protrusion for connection detection (not shown) of the counterpart connector is inserted into an internal space in the main body portion 81. The main body part 81 is integrally provided with the projecting part 82 which projects rearward from a rear wall of the main body part 81. The projecting part 82 comprises a central projecting part 83 which projects rearward from a central part of the rear wall of the main body part 81 in the width direction and extends in the top-down direction, and a pair of flat plate parts 84 which extend both sides in the width direction from a central part of the central projecting part 83 in the top-down direction and extend forward from the rear wall of the main body part 81. A cantilevered elastic part 85 extending in the front-back direction is integrally formed at an outer end edge in the width direction of each flat plate part 84.Fixed and free end positions of the elastic part 85 on one side in the width direction and of the elastic part 85 on the other side in the width direction are opposite each other in the front-back direction. A downward projection 85a is formed at the free end of each elastic part 85. The main body part 81 is formed of a pair of flat, plate-shaped flange parts 86 which are continuous from the rear wall of the main body part 81, project outwards on both sides in the width direction, and extend in the top-down direction. A press-fitted hollow portion 83a, opening towards the front and hollow towards the rear, is formed inside the central projecting portion 83 (see [Fig. 9]). The press-fitted hollow portion 83a communicates with the internal space of the main body part 81 in the front-to-rear direction. The base portion 91 (see [Fig. 3]) of the short terminal 90 is press-fitted into the press-fitted hollow portion 83a from the front. Thus, the short terminal 90 is fixed to the second housing 80 such that the pair of terminal portions 92 project forward from the rear wall of the main body part 81 and are positioned within the internal space. of the main body part 81. The second housing 80 is mounted on the first housing 30 by inserting the protruding part 82 (the central protruding part 83 and the pair of flat plate parts 84) into the recessed part 37 of the first housing 30 in subassembly 2 from the front side (see Figures 7 to 9). In a state in which the protruding part 82 is inserted into the recessed part 37 of the first housing 30, as shown in Figures 7 to 9, a space H is formed around a lateral face of the protruding part 82, so that the protruding part 82 (i.e. the second housing 80) can be moved in any direction perpendicular to the front-to-back direction with respect to the recessed part 37 (i.e. the first housing 30).When the second housing 80 is moved downwards relative to the first housing 30 in a state where the protruding part 82 is inserted into the hollow part 37 of the first housing 30, the protrusions 85a of the pair of elastic parts 85 come into contact with a lower wall of the hollow part 37. When the second housing 80 is pushed downwards from this state, the pair of elastic parts 85 is elastically deformed upwards by an upward force received by the pair of protrusions 85a from the lower wall of the hollow part 37, and the second housing 80 is pushed upwards by a downward elastic restoring force of the pair of elastic parts 85. Next, the front support 70 will be described. The front support 70 serves to prevent the trim pieces 60 and the second housing 80 from falling towards the front side of the first housing 30. The front support 70 is a resin molded product and comprises a tubular portion 71 as shown in [Fig. 2]. The tubular portion 71 has a tubular shape extending in the front-to-back direction and an elongated flat shape in the width direction, corresponding to the outer peripheral shape of the connecting portion 32 of the first housing 30 when viewed from the front-to-back direction. A rectangular notch 71a, hollowed out towards the rear from a front end of the tubular portion 71, is formed in the central part of a lower portion of the tubular portion 71 in the width direction. The notch 71a is provided to prevent interference between the main body portion 81 of the second housing 80 and the front support 70. In the tubular section 71, a flat-plate partition wall 72 is formed at a position on the front side of the center of the tubular section 71 in the front-to-back direction to partition an internal space of the tubular section 71 into front and rear spaces. Slots 73 (through holes) extending in the width direction, through which the terminal portions 11 of the pair of end fittings 10 are inserted, are formed in the partition wall 72. A rectangular notch 74 is formed in the partition wall 72 at a central portion in the width direction of a lower portion of the slot 73. The upper end of the notch 74 communicates with the slots 73, and a lower end of the notch 74 communicates with the notch 71a. Like the notch 71a, the notch 74 is also provided to prevent interference between the main body part 81 of the second housing 80 and the front support 70. In a state where the fittings 60 and the second housing 80 are mounted on the sub-assembly 2, the front support 70 is mounted on the outer periphery of the connecting part 32 from the front side such that the terminal parts 11 of the pair of terminal fittings 10 are inserted through the slots 73 and the main body part 81 of the second housing 80 passes through the notch 74 (see figures 1, 7, etc.). In a fully mounted position, the front portions of the terminal sections 11 of the pair of end fittings 10 and a front portion of the main body portion 81 of the second housing 80 protrude forward from the partition wall 72 of the front support 70. In other words, the pair of terminal sections 11 and the pair of terminal sections 92 of the short terminal 90 attached to the second housing 80 are exposed at the front. In the fully mounted position, as shown in [Fig. 7], the locking hole 32a provided on the outer periphery of the connection portion 32 and the locking projection 75 provided on the front support 70 are engaged, so that the front support 70 is prevented from protruding forward from the first housing 30. As will be understood from [Fig. 8], in the state in which the front support 70 is fully mounted, the tubular portion 71 is positioned adjacent to the front side of the trim 60, so that the trim 60 is prevented from falling forward from the first housing 30; and the pair of flange portions 86 of the second housing 80 are clamped in the front-to-back direction by the front end of the first housing 30 (the front end of the connecting portion 32) and the separating wall 72 of the front support 70, so that the front support 70 is prevented from falling forward from the first housing 30. As described above, after the front support 70 is fully mounted, the assembly of the connector 1 is completed, and the connector shown in [Fig. 1] is obtained. The constituent elements of the connector 1 have been described above. In an assembled state of connector 1, even when the second housing 80 is moved in any direction perpendicular to the front-to-back direction relative to the first housing 30 within a range of the space H described above (see Figures 7 to 9), the main body portion 81 of the second housing 80 does not interfere with an edge portion of the notch 71a and an edge portion of the notch 74 of the front support 70 (see [Fig. 6]). In other words, the second housing 80, fixed to the connecting portion 32 (recessed portion 37) of the first housing 30, is movable within a any direction perpendicular to the front-to-back direction relative to the first housing 30 in the range of space H while maintaining a position in which the pair of terminal parts 92 of the short terminal 90 faces the counterpart connector. The assembled connector 1 is connected to the corresponding connector. To connect connector 1 and the corresponding connector, a tubular connecting portion of the corresponding connector is inserted externally into the connecting portion 32 of connector 1. When the connecting portion is inserted externally into the connecting portion 32, the connection protrusion for connection detection provided on the corresponding connecting portion is inserted into the internal space of the main body portion 81 of the second housing 80. A pair of female terminal portions (not shown) corresponding to the pair of terminal portions 92 of the short terminal 90 is placed in the connection protrusion for connection detection. The pair of female terminal portions is connected to a signal circuit for connection detection provided in the corresponding connector.In a state in which the pair of female terminal parts is not respectively connected to the pair of terminal parts 92 of the short terminal 90, the connection detection signal circuit is disconnected. When the connector and its counterpart are connected, the connection protrusion for connection detection of the counterpart connector is inserted into the internal space of the main body part 81, so that the pair of terminal parts 92 of the short terminal 90 and the pair of female terminal parts are electrically connected to each other. As a result, the signal circuit for connection detection is activated. In this way, by electrically detecting the transition from disconnection to connection of the connection detection signal circuit, the connection of the connector and its counterpart connector is detected. Here, as described above, in connector 1, the second housing 80, in which the short terminal 90 is stored, is movable relative to the first housing 30 in any direction perpendicular to the front-to-back direction within the range of space H relative to the first housing 30 (connecting part 32). Thus, when connector 1 and the counterpart connector are connected to each other, even if a positional deviation (a positional deviation in a direction perpendicular to the front-to-back direction) occurs between the terminal portions 92 of the short terminal 90 and the female terminal portions of the counterpart connector due to a manufacturing tolerance of connector 1, a manufacturing tolerance of the counterpart connector, or the like, the positional deviation can be absorbed by relatively displacing the second housing 80 with respect to the first housing 30 (the connecting part 32) within a direction in which the position gap disappears. Furthermore, in the case where the counterpart connector is not provided with the connection detection signal circuit (including the connection protrusion for connection detection and the pair of female terminal parts), the connector 1 can be changed into a structure which does not include the short terminal 90 by simply omitting the attachment of the second housing 80, in which the short terminal 90 is stored, to the first housing 30, without changing the shape or otherwise of the additional elements constituting the connector |. <Fonction et Effets> As described above, according to the connector in this embodiment, the second housing 80 with the short terminal 90 is attached to the first housing 30 separately from the first housing 30, which constitutes the connecting portion (connecting portion 32) to be connected to the corresponding connector. The second housing 80 is attached to the first housing 30 in a position where it can be moved in a direction intersecting the direction of connection with the corresponding connector, in which the short terminal 90 faces the corresponding connector. Therefore, a displacement of the second housing 80 can compensate for a positional displacement due to a manufacturing tolerance or similar. Thus, in the connector 1 according to this embodiment, alignment of the short terminal 90 is straightforward. Furthermore, the protruding portion 82 of the second housing 80 is inserted into the recessed portion 37 of the first housing 30, and there is a displacement gap (space H) between the protruding portion 82 and the inner wall of the recessed portion 37, such that the second housing 80 can be moved in the direction intersecting the connection direction. Thus, the second housing 80 can be fixed to the first housing 30 in a movable manner. In addition, the second housing 80 is fixed to the connecting part (connecting portion 32) of the first housing 30, so that the connector 1 can be reduced in size, compared to a case where the second housing 80 is fixed to another position of the first housing 30. <Autres Modes de réalisation> This disclosure is not limited to the above embodiment, and various modifications may be adopted within the scope of the present invention. For example, this disclosure is not limited to the above embodiment and may be modified, improved, or otherwise similar as appropriate. Furthermore, the materials, shapes, dimensions, numbers, arrangement locations, or similar features of the constituent elements in the above embodiment are optional and not limited to the extent that the purpose of this disclosure can be achieved. In the embodiment above, in the state in which the protruding part 82 of the second housing 80 is inserted into the recessed part 37 of the first housing 30, the space H is formed around the lateral face of the projecting part 82, such that the second housing 80 is movable in any direction perpendicular to the front-to-back direction relative to the first housing 30. In this regard, the second housing 80 can be fixed to the first housing 30 by any structure as long as the second housing 80 can be moved relative to the first housing 30 in any direction perpendicular to the front-to-back direction. Furthermore, in the above embodiment, the second housing 80 is fixed to the connecting part (connecting portion 32) of the first housing 30. Alternatively, the second housing 80 can be fixed to a part of the first housing 30 other than the connecting part (connecting portion 32). Here, connector 1 according to the embodiment of this disclosure described above will be briefly summarized and mentioned in [1] to [3] below. [1] Connector (1) comprising: a terminal fitting (10); an electrical wire (20) connected to the terminal fitting (10); a first housing (30) in which the terminal fitting (10) is stored, the first housing (30) constituting a connection part (32) with a corresponding connector; a sealing element (60) arranged to surround an outer periphery of the first housing (30); a front support (70) mounted on the first housing (30) so as to prevent the sealing element (60) from coming out of the first housing (30); and a second housing (80) comprising a short terminal (90), the short terminal (90) being configured to allow detection of a connection state with the counterpart connector, in which the second housing (80) is fixed to the first housing (30) and retained by the front support (70) in a state in which the second housing (80) is movable in a direction intersecting a connection direction with the counterpart connector in a position in which the short terminal (90) faces the counterpart connector. According to the connector with configuration [1], the second housing containing the short terminal is attached to the first housing separately from the first housing, which forms part of the connection with the corresponding connector. The second housing is attached to the first housing in such a way that it can be moved in a direction intersecting the connection direction with the corresponding connector, to a position where the short terminal faces the corresponding connector. Therefore, a displacement of the second housing can compensate for a positional displacement due to manufacturing tolerances or similar factors. Consequently, in the connector of this configuration, alignment of the short terminal is straightforward. [2] Connector {1) according to [1], wherein the second housing (80) comprises a protruding portion (82) projecting in a direction away from the corresponding connector, in which the first housing (30) has a hollowed-out portion (37) into which the protruding portion (82) is inserted, in which the projecting part (82) and an inner wall of the hollowed part (37) define a displacement space (H) between them, and in which the displacement space (H) allows the second housing (80) to be moved in a direction intersecting the connection direction. According to the connector with configuration [2], the protruding part of the second housing is inserted into the recessed part of the first housing, and the displacement space is defined between the protruding part and the inner wall of the recessed part, such that the second housing is movable in the direction intersecting the connection direction. Thus, the second housing can be fixed to the first housing 30 in a movable manner. [3] Connector (1) according to [1] or [2]. in which the second box (80) is fixed to the connecting part (32) of the first box (30).
