Description

Technical Field

[0001] This disclosure relates to a connector capable of detecting the assembly status of a corresponding connector. Background Technology

[0002] Patent document 1 discloses a connector in which a plate-shaped terminal block for connection to a device such as an inverter is stored in a housing. This type of connector is commonly referred to as a high-voltage connector.

[0003] Patent Document 1: JP2020-187918A Summary of the Invention

[0004] Connectors in related fields, such as high-voltage connectors, as described above, can be designed to detect the assembly status between the connector and its counterpart from a safety perspective. For example, a small U-shaped terminal block (so-called short-circuit terminal) is embedded in the housing, and during assembly, the short-circuit terminal is brought into contact with the paired electrodes in the corresponding connector to form a short circuit, so that the assembly status can be detected. However, when excessive positional deviation occurs between the short-circuit terminal and the electrodes of the corresponding connector due to connector manufacturing tolerances, it may be difficult to connect the short-circuit terminal to the electrodes of the corresponding connector even if the assembly itself is performed properly.

[0005] The purpose of this disclosure is to provide a connector in which short-circuit terminals can be easily aligned.

[0006] This disclosure provides a connector comprising: a terminal connector; a wire connected to the terminal connector; a first housing wherein the terminal connector is stored, the first housing constituting an assembly portion for assembly with a corresponding connector; a sealing assembly portion disposed around the outer periphery of the first housing; a front retainer mounted on the first housing to prevent the sealing assembly portion from detaching from the first housing; and a second housing including a short-circuit terminal configured to allow detection of an assembly state with a corresponding connector, wherein the second housing is attached to the first housing and held by the front retainer in a state in which the second housing can be displaced in an orientation with the short-circuit terminal facing the corresponding connector in a direction intersecting with the assembly direction of the corresponding connector.

[0007] The present disclosure has been briefly described above. Furthermore, the details of the present disclosure will be further clarified by referring to the accompanying drawings and reading through the embodiments of the invention described below. Attached Figure Description

[0017] <Example>

[0018] In the following description, connector 1 according to an embodiment of the present disclosure will be described with reference to the accompanying drawings. Figure 1 The connector 1 shown acts as a relay connector, electrically connecting the paired wires 20 of connector 1 to the corresponding connector (not shown) to be assembled into connector 1. Connector 1 includes a short-circuit terminal 90 (see [link to documentation]). Figure 1 , 3 The short-circuit terminal 90 is configured to allow detection of the assembly status with the corresponding connector. The specific function of the short-circuit terminal 90 will be described later.

[0019] For ease of description, the following is as follows: Figure 1 As shown, the "front-back direction," "vertical direction," and "width direction" are defined. The "front-back direction," "vertical direction," and "width direction" are orthogonal to each other. The front-back direction is consistent with the assembly direction of connector 1 and the corresponding connector, and "front" and "rear" correspond to the forward and backward sides of the assembly of connector 1 and the corresponding connector, respectively.

[0020] like Figure 1 and 2As shown, connector 1 includes a pair of terminal connectors 10, a pair of wires 20 connected to the pair of terminal connectors 10, a first housing 30 for storing the pair of terminal connectors 10, a shielding housing 40 mounted on the first housing 30 from the rear, a protective cover 50 covering the shielding housing 40 and the pair of wires 20, an encapsulation assembly portion 60 mounted on the first housing 30 from the front, a front retainer 70, a second housing 80, and a short-circuit terminal 90 mounted on the second housing 80. Each assembly portion constituting connector 1 will be described sequentially below.

[0021] First, the terminal connector 10 and the wire 20 will be described. The terminal connector 10 is formed by pressing, bending, etc., on a metal plate and has a shape extending in the front-rear direction. The terminal connector 10 generally includes a terminal portion 11 in the shape of an elongated flat plate extending in the front-rear direction (see...). Figure 1 , 2 , 8, etc.), and connecting part 12 (see Figure 8 The connecting portion 12 is located at the rear end of the terminal portion 11. The end of the wire 20 is connected to the connecting portion 12.

[0022] like Figure 8 As shown, the wire 20 includes a conductor core 21 made of metal and an insulating sheath 22 covering the conductor core 21. At the end of the wire 20, the insulating sheath 22 is removed to expose the conductor core 21, and the connection portion 12 of the terminal connector 10 is crimped and secured to the exposed conductor core 21. Thus, the wire 20 connected to the terminal connector 10 extends rearward from the connection portion 12 of the terminal connector 10.

[0023] Next, the first housing 30 will be described. The first housing 30 is a resin molded article. Figure 2 , 7 As shown in Figures 8, the first housing 30 has a tubular shape extending in the front-rear direction and a flat shape elongated in the width direction when viewed in the front-rear direction. A radially outwardly projecting flange portion 31 is formed on the entire outer periphery of the central portion of the first housing 30 in the front-rear direction. A portion of the first housing 30 on the front side of the flange portion 31 constitutes a mounting portion 32, which is inserted into and mounted to a corresponding tubular mounting portion (not shown) of a corresponding connector, and a portion of the first housing 30 on the rear side of the flange portion 31 constitutes an insertion portion 33, which is inserted into the shielding housing 40 (see Figure 8). Figure 7 and 8 ).

[0024] In the first housing 30, the paired terminal insertion holes 34, the paired terminal storage chambers 35, and the paired package assembly storage portions 36 are formed sequentially from front to rear at corresponding paired positions arranged at intervals in the width direction, so as to communicate with each other in the front-rear direction. The front end of the terminal insertion hole 34 leads to the front end of the first housing 30 (the front end of the assembly portion 32), and the rear end of the package assembly storage portion 36 leads to the rear end of the first housing 30 (the rear end of the insertion portion 33).

[0025] The terminal portion 11 of the terminal connector 10 is inserted into the terminal insertion hole 34, the connecting portion 12 of the terminal connector 10 is stored in the terminal storage chamber 35, and the encapsulation assembly portion 93 covering the outer periphery of the paired wires 20 (see Figure 8 (As will be described below) is stored in the packaging assembly storage section 36 (see Figure 8 ).

[0026] A forward-opening and rearward-recessed recessed portion 37 is formed in the lower portion of the paired terminal insertion hole 34 in the assembly portion 32 of the first housing 30 (see...). Figures 7 to 9 The protruding portion 82 of the second housing 80 (see...) Figure 3 (etc., as described below) is inserted into the recessed portion 37 (see Figures 7 to 9 ).

[0027] Next, the shielding housing 40 will be described. For example... Figure 1 , 2 As shown in Figures 7 and 8, the shielding housing 40, made of metal, has a tubular shape extending in the front-rear direction so as to be externally inserted into the insertion portion 33 of the first housing 30. The shielding housing 40 is mounted to the insertion portion 33 of the first housing 30 from the rear and has the function of preventing electromagnetic noise from being transmitted to the paired wires 20 located inside the first housing 30.

[0028] Next, the protective cover 50 will be described. For example... Figure 1 As shown in Figure 2, the rubber protective cover 50 has a tubular shape extending in the front-rear direction, and generally includes a large-diameter portion 51 covering the outer periphery of the shielding housing 40, a small-diameter portion 52 covering the outer periphery of the paired wires 20 extending rearward from the shielding housing 40, and a connecting portion 53 connecting the large-diameter portion 51 and the small-diameter portion 52. The protective cover 50 has the function of protecting the paired wires 20 extending rearward from the shielding housing 40.

[0029] The aforementioned paired terminal connectors 10, paired wires 20, first housing 30, shielding housing 40, and protective cover 50 constitute sub-assembly part 2 (see...). Figure 2 Subassembly part 2 is part of connector 1. Subassembly part 2 is assembled according to the following steps.

[0030] First, the paired wires 20 are inserted into the protective cover 50 and the shielding housing 40 by sequentially inserting the ends of the paired wires 20 from the rear into the hollow portions of the protective cover 50 and the shielding housing 40. Next, the paired wires 20 are inserted through the retainer 94 (see...). Figure 7 and 8 Paired through holes 95 (see) Figure 8 The wires 20 are formed in a retainer 94 made of resin so as to be spaced apart from each other in the width direction. The pair of wires 20 are inserted through the retainer 94 by inserting the ends of the wires 20 from the rear into the pair through-holes 95. Next, each of the pair of wires 20 is inserted through an annular encapsulation assembly portion 93 made of rubber (see...). Figure 8 Next, the connection portion 12 of the terminal connector 10 is crimped and secured to the exposed conductor core 21 at the end of each wire 20.

[0031] Next, the paired terminal connectors 10 to which the paired wires 20 are connected are stored in the first housing 30. Therefore, each terminal connector 10 is inserted into the first housing 30 from the rear. Thus, the terminal portion 11 is inserted into the corresponding terminal insertion hole 34, and the connecting portion 12 is stored in the corresponding terminal storage chamber 35. With the terminal connector 10 fully inserted, the front portion of the paired terminal portion 11 protrudes forward from the front end of the first housing 30 (the front end of the assembly portion 32) (see [reference]). Figure 2 And the paired wires 20, extending rearward from the paired terminal connector 10, extend rearward from the rear end of the first housing 30 (the rear end of the insertion portion 33). Figure 8 As shown, when the terminal connector 10 is fully inserted, the locking hole 11a provided in the terminal portion 11 engages with the locking protrusion 34a provided in the terminal insertion hole 34, thereby preventing the terminal connector 10 from disengaging from the first housing 30 to the rear side.

[0032] Next, the paired wires 20 are inserted through the paired encapsulation assembly portion 93 and moved forward relative to the paired wires 20 stored in the paired encapsulation assembly portion storage portion 36 of the first housing 30, and the paired wires 20 are inserted through the retainer 94 and moved forward relative to the paired wires 20 mounted on the rear end (rear end of the insertion portion 33) of the first housing 30. With the encapsulation assembly portion 93 fully stored, the encapsulation assembly portion 93 is pressed and clamped between the outer peripheral surface of the wires 20 and the inner peripheral surface of the encapsulation assembly portion storage portion 36 (see...). Figure 8 It also has the function of sealing the gap between the wire 20 and the storage portion 36 of the encapsulation assembly part. When the retainer 94 is fully installed, as... Figure 8As shown, the locking hole 96 provided in the retainer 94 engages with the locking protrusion 33a provided on the outer periphery of the insertion portion 33, thereby preventing the retainer 94 from falling off the first housing 30 to the rear side. The retainer 94 is configured to be adjacent to the paired sealing assembly portion 93 on the rear side in order to prevent the paired sealing assembly portion 93 from falling off the first housing 30 to the rear side.

[0033] Next, the paired wires 20 are inserted through the shielding housing 40 and installed from the rear into the insertion portion 33 of the first housing 30. Therefore, the shielding housing 40 is externally inserted into the insertion portion 33 of the first housing 30. Figure 7 As shown, when the shielding housing 40 is fully installed, the locking assembly part 41 provided in the shielding housing 40 engages with the locking hole 33b provided in the outer periphery of the insertion part 33, thereby preventing the shielding housing 40 from falling from the first housing 30 to the rear side.

[0034] Next, the protective cover 50 through which the paired wires 20 are inserted is moved forward relative to the paired wires 20, and the large-diameter portion 51 of the protective cover 50 is mounted on the outer periphery of the shielding housing 40. Therefore, the installation of the protective cover 50 is completed, and the assembly sub-assembly part 2 is completed, thus obtaining... Figure 2 The sub-assembly part 2 shown in the diagram.

[0035] Next, the package assembly part 60 will be described. For example... Figure 2 As shown, the rubber-encapsulated assembly part 60, made of rubber, has a tubular shape extending in the front-rear direction, and a flat shape corresponding to the outer periphery of the assembly part 32 of the first housing 30, which extends in the width direction when viewed in the front-rear direction. The encapsulated assembly part 60 is mounted from the front onto the outer periphery of the assembly part 32 of the sub-assembly assembly part 2 (see...). Figure 1 (e.g., 7, etc.). When connector 1 and the corresponding connector are assembled such that the tubular corresponding assembly portion of the corresponding connector is externally inserted into the assembly portion 32, the encapsulation assembly portion 60 mounted on the assembly portion 32 is pressed and clamped between the outer peripheral surface of the assembly portion 32 and the inner peripheral surface of the corresponding assembly portion. This provides the function of sealing the gap between the assembly portion 32 and the corresponding assembly portion.

[0036] Next, the second housing 80 and the short-circuit terminal 90 will be described. The second housing 80 is a resin molded product and has the function of holding the short-circuit terminal 90, which provides the function of detecting the assembly status with the corresponding connector. Figure 3 As shown, the short-circuit terminal 90 generally includes a flat base portion 91 extending in the front-back direction and the up-down direction, and a pair of rod-shaped terminal portions 92 extending forward from the upper and lower ends of the front end of the base portion 91.

[0037] like Figures 3 to 5 As shown, the second housing 80 includes a rectangular tubular body portion 81 extending in the front-rear direction. The body portion 81 opens to the front and closes to the rear by a rear wall (not shown). When connector 1 and its corresponding connector are assembled together, an assembly protrusion for assembly detection (not shown) of the corresponding connector is inserted into the interior space of the body portion 81.

[0038] The main body portion 81 is integrally provided with a protruding portion 82 that protrudes rearward from the rear wall of the main body portion 81. The protruding portion 82 includes a central protruding portion 83 that protrudes rearward in the width direction and extends vertically from the center portion of the rear wall of the main body portion 81; and a pair of flat plate portions 84 that extend laterally in the width direction from the center portion of the central protruding portion 83 in the vertical direction and extend forward from the rear wall of the main body portion 81. A cantilevered elastic mounting portion 85 extending in the front-rear direction is integrally formed at the outer edge of each flat plate portion 84 in the width direction. The positions of the fixed end and free end of the elastic mounting portion 85 on one side in the width direction and the positions of the fixed end and free end of the elastic mounting portion 85 on the other side in the width direction are opposite to each other in the front-rear direction. A downwardly protruding protrusion 85a is formed at the free end of each elastic mounting portion 85. The main body 81 has a pair of flat flange portions 86, which are continuous from the rear wall of the main body 81, protrude to both sides in the width direction, and extend in the vertical direction.

[0039] A press-fit recessed portion 83a is formed within the central protrusion 83, opening to the front and recessed to the rear (see...). Figure 9 The press-fit recessed portion 83a communicates with the internal space of the main body portion 81 in the front-rear direction. The base portion 91 of the short-circuit terminal 90 (see...) Figure 3 The short-circuit terminal 90 is press-fitted into the press-fit recess 83a from the front side. Therefore, the short-circuit terminal 90 is fixed to the second housing 80, such that the paired terminal portions 92 protrude forward from the rear wall of the main body portion 81 and are positioned in the internal space of the main body portion 81.

[0040] The second housing 80 is mounted on the first housing 30 by inserting the protrusion 82 (central protrusion 83 and paired flat plate portions 84) from the front into the recess 37 of the first housing 30 in the sub-assembly assembly part 2 (see [link]). Figures 7 to 9 With the protruding portion 82 inserted into the recessed portion 37 of the first housing 30, as... Figures 7 to 9As shown, a gap H is formed around the side of the protrusion 82, allowing the protrusion 82 (i.e., the second housing 80) to be displaced relative to the recess 37 (i.e., the first housing 30) in any direction perpendicular to the front-rear direction. When the second housing 80 moves downward relative to the first housing 30 with the protrusion 82 inserted into the recess 37 of the first housing 30, the protrusions 85a of the paired elastic fitting portions 85 contact the bottom wall of the recess 37. When the second housing 80 is pressed downward from this state, the paired elastic fitting portions 85 elastically deform upward by the upward force received from the bottom wall of the recess 37 by the paired protrusions 85a, and the second housing 80 is pushed back upward by the downward elastic restoring force of the paired elastic fitting portions 85.

[0041] Next, the front retainer 70 will be described. The front retainer 70 functions to prevent the encapsulation assembly portion 60 and the second housing 80 from falling off the first housing 30 to the front side. The front retainer 70 is a resin molded article and includes, as... Figure 2 The tubular portion 71 is shown. The tubular portion 71 has a tubular shape extending in the front-rear direction and, when viewed in the front-rear direction, a flat shape corresponding to the outer periphery of the mounting portion 32 of the first housing 30, extending in the width direction. A rectangular notch 71a, recessed from the front end of the tubular portion 71 toward the rear side, is formed in the center portion of the 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 retainer 70.

[0042] In the tubular portion 71, a flat partition wall 72 is formed at the front side of the center of the tubular portion 71 in the front-rear direction to divide the internal space of the tubular portion 71 into front and rear spaces. A slit 73 (through hole) extending in the width direction is formed in the partition wall 72, into which the terminal portions 11 of the paired terminal connectors 10 are inserted. A rectangular recess 74 is formed in the partition wall 72 at the center of the lower portion of the slit 73 in the width direction. The upper end of the recess 74 communicates with the slit 73, and the lower end of the recess 74 communicates with the recess 71a. Similar to the recess 71a, a recess 74 is also provided to prevent interference between the main body portion 81 of the second housing 80 and the front retainer 70.

[0043] With the encapsulation assembly portion 60 and the second housing 80 mounted on the sub-assembly assembly portion 2, the front retainer 70 is mounted from the front on the outer periphery of the assembly portion 32, such that the terminal portions 11 of the paired terminal connectors 10 are inserted through the slit 73 and the main body portion 81 of the second housing 80 passes through the recess 74 (see...). Figure 1 , 7 wait).

[0044] With the front retainer 70 fully installed, the front portions of the terminal portions 11 of the paired terminal connectors 10 and the front portions of the main body portion 81 of the second housing 80 protrude forward from the partition wall 72 of the front retainer 70. In other words, the paired terminal portions 11 and the paired terminal portions 92 of the short-circuit terminals 90 fixed to the second housing 80 are exposed forward. With the front retainer 70 fully installed, as... Figure 7 As shown, the locking hole 32a provided on the outer periphery of the assembly part 32 and the locking protrusion 75 provided on the front retainer 70 engage with each other to prevent the front retainer 70 from disengaging from the first housing 30 to the front side.

[0045] from Figure 8 It is understood that, with the front retainer 70 fully installed, the tubular portion 71 is positioned adjacent to the front side of the encapsulation assembly portion 60 to prevent the encapsulation assembly portion 60 from falling from the first housing 30 to the front side; and the paired flange portions 86 of the second housing 80 are clamped in the front-rear direction by the front end of the first housing 30 (the front end of the assembly portion 32) and the partition wall 72 of the front retainer 70 to prevent the front retainer 70 from falling from the first housing 30 to the front side. As described above, after the front retainer 70 is installed, the connector 1 is assembled and obtained. Figure 1 The connector 1 is shown. The assembly parts constituting connector 1 have been described above.

[0046] In the assembled state of connector 1, even when the second housing 80 is displaced relative to the first housing 30 in any direction perpendicular to the front-rear direction within the aforementioned gap H (see... Figures 7 to 9 The main body portion 81 of the second housing 80 does not interfere with the edge portion of the notch 71a and the edge portion of the notch 74 of the front retainer 70 (see...). Figure 6 In other words, the second housing 80, which is attached to the mounting portion 32 (recessed portion 37) of the first housing 30, can be displaced relative to the first housing 30 in any direction perpendicular to the front-back direction within the gap H, while maintaining the orientation of the paired terminal portions 92 of the short-circuit terminal 90 facing the corresponding connector.

[0047] The assembled connector 1 is assembled to the corresponding connector. To assemble connector 1 and the corresponding connector to each other, the tubular corresponding assembly portion of the corresponding connector is externally inserted into the assembly portion 32 of connector 1. When the corresponding assembly portion is externally inserted into the assembly portion 32, the assembly protrusion for assembly detection, provided on the corresponding assembly portion, is inserted into the internal space of the main body portion 81 of the second housing 80. Paired female terminals (not shown) corresponding to the paired terminal portions 92 of the short-circuit terminal 90 are stored in the assembly protrusion for assembly detection. The paired female terminal portions are connected to a signal circuit for assembly detection provided in the corresponding connector. When the paired female terminal portions are not respectively connected to the paired terminal portions 92 of the short-circuit terminal 90, the signal circuit for assembly detection is disconnected.

[0048] When connector 1 and its corresponding connector are assembled together, the assembly protrusion of the corresponding connector for assembly detection is inserted into the internal space of the main body portion 81, so that the paired terminal portion 92 of the short-circuit terminal 90 is electrically connected to the paired female terminal portion. Therefore, the signal circuit for assembly detection is connected. In this way, by electrically detecting the transition of the signal circuit for assembly detection from disconnection to connection, the assembly of connector 1 and its corresponding connector is detected.

[0049] Here, as described above, in connector 1, the second housing 80 storing the short-circuit terminal 90 can be displaced relative to the first housing 30 in any direction perpendicular to the front-rear direction within the gap H relative to the first housing 30 (assembly portion 32). Therefore, when connector 1 and the corresponding connector are assembled together, even if a positional deviation (positional deviation in the direction perpendicular to the front-rear direction) occurs between the terminal portion 92 of the short-circuit terminal 90 and the female terminal portion of the corresponding connector due to manufacturing tolerances of connector 1, manufacturing tolerances of the corresponding connector, etc., the positional deviation can be absorbed by moving the second housing 80 relative to the first housing 30 (assembly portion 32) in the direction in which the positional deviation disappears.

[0050] Furthermore, if the corresponding connector does not have a signal circuit for assembly detection (including assembly protrusions and paired female terminals for assembly detection), the connector 1 can be modified to have a structure that does not include the short-circuit terminal 90 by simply omitting the attachment of the second housing 80 to the first housing 30 that stores the short-circuit terminal 90 without changing the shape of other assembly parts constituting the connector 1.

[0051] <Functions and Effects>

[0052] As described above, in the connector 1 according to this embodiment, the second housing 80, having a short-circuit terminal 90, is attached separately to the first housing 30, which constitutes the assembly portion (assembly part 32) to be assembled to the corresponding connector. The second housing 80 is attached to the first housing 30 in a state where it is displaced in a direction intersecting the assembly direction of the mating connector with the short-circuit terminal 90 facing the corresponding connector. Therefore, the displacement of the second housing 80 can absorb positional displacement caused by manufacturing tolerances, etc. Therefore, in the connector 1 according to this embodiment, alignment of the short-circuit terminal 90 is easy.

[0053] Furthermore, the protruding portion 82 of the second housing 80 is inserted into the recessed portion 37 of the first housing 30, and a displacement gap (gap H) exists between the protruding portion 82 and the inner wall of the recessed portion 37, allowing the second housing 80 to be displaced in a direction intersecting the assembly direction. Therefore, the second housing 80 can be attached to the first housing 30 in a displaceable manner.

[0054] Furthermore, the second housing 80 is attached to the assembly portion (assembly portion 32) of the first housing 30, which allows the connector 1 to be smaller in size compared to the case where the second housing 80 is attached to another location of the first housing 30.

[0055] (Other embodiments)

[0056] This invention is not limited to the above embodiments, and various modifications can be made within the scope of this invention. For example, this disclosure is not limited to the above embodiments, and can be appropriately modified, improved, etc. In addition, the materials, shapes, sizes, quantities, and arrangement positions of the constituent assembly parts in the above embodiments are optional and not limited, as long as the purpose of this disclosure can be achieved.

[0057] In the above embodiment, with the protruding portion 82 of the second housing 80 inserted into the recessed portion 37 of the first housing 30, a gap H is formed around the side of the protruding portion 82, allowing the second housing 80 to be displaced relative to the first housing 30 in any direction perpendicular to the front-rear direction. In this respect, as long as the second housing 80 can be displaced relative to the first housing 30 in any direction perpendicular to the front-rear direction, the second housing 80 can be attached to the first housing 30 by any structure.

[0058] Furthermore, in the above embodiment, the second housing 80 is attached to the assembly portion (assembly portion 32) of the first housing 30. Alternatively, the second housing 80 may be attached to a portion of the first housing 30 that is different from the assembly portion (assembly portion 32).

[0065] A front retainer (70) is mounted on the first housing (30) to prevent the sealing assembly part (60) from detaching from the first housing (30); and

[0066] The second housing (80) includes a short-circuit terminal (90) configured to allow detection of the assembly status with the corresponding connector.

[0067] In the case where the second housing (80) is displaced in a posture with the short-circuit terminal (90) facing the corresponding connector in a direction intersecting with the assembly direction of the corresponding connector, the second housing (80) is attached to the first housing (30) and held by the front retainer (70).

[0068] According to the connector with this configuration [1], the second housing with short-circuit terminals is separately attached to the first housing, and the first housing constitutes an assembly portion for assembly with the corresponding connector. The second housing is attached to the first housing in a state where it is displaced in a direction intersecting the assembly direction of the mating connector with the short-circuit terminals facing the corresponding connector. Therefore, the displacement of the second housing can absorb positional displacement caused by manufacturing tolerances, etc. Therefore, in this connector configuration, alignment of the short-circuit terminals is easy.

[0069] [2] According to connector (1) of [1], where,

[0070] The second housing (80) includes a protrusion (82) that projects in a direction away from the corresponding connector.

[0071] The first housing (30) has a recess (37) for inserting the protrusion (82).

[0072] The inner walls of the protruding portion (82) and the recessed portion (37) define a displacement gap (H) between them, and

[0073] The displacement gap (H) allows the second housing (80) to be displaced in a direction intersecting the assembly direction.

[0074] According to the connector having the configuration [2], the protruding portion of the second housing is inserted into the recessed portion of the first housing, and the displacement gap is defined between the protruding portion and the inner wall of the recessed portion, so that the second housing can be displaced in a direction intersecting the assembly direction. Therefore, the second housing can be attached to the first housing in a displaceable manner.

[0075] [3] According to connector (1) of [1] or [2], wherein,

[0076] The second housing (80) is attached to the assembly portion (32) of the first housing (30).

[0077] According to the connector with configuration [3], the second housing is attached to the assembly portion of the first housing, which reduces the overall size of the connector compared to the case where the second housing is attached to another portion.
