Description

[0001] The present disclosure relates to a first connector, a second connector and a connector arrangement.

[0002] Conventionally, wiring or cabling comprising a wire and a connector mounted or arranged on an end of the wire is known as wiring for installation in a vehicle, such as a hybrid or electric vehicle. The connector includes a terminal made of metal and connected to the end of the wire, and a connector housing for holding the terminal (see, for example, Japanese unexamined patent publication JP 2020-080 269 A).

[0003] However, if vibration is applied to the aforementioned connector, the connector housing can move relative to a mating or matched connector, and the terminal held within the connector housing can also move relative to a mating or matched terminal. If the terminal moves relative to its mating terminal, a problem arises: the contact point between the terminal and its mating terminal will wear out.

[0004] US 2019 / 0044267A1 discloses a high-current electrical connector with a multi-point contact spring. The high-current electrical connector comprises an electrical socket and a contact spring. The electrical socket is configured to accept an electrical plug and is made from a single piece of electrically conductive material. The electrical socket has a first side wall and a second side wall. The second side wall defines a distal end, a proximal end, and a mid-range. The first side wall is opposite and parallel to the distal end of the second side wall. The contact spring is made from a single piece of electrically conductive material and is positioned between the first and second side walls. The contact spring defines a plurality of opposing pairs of contact bars.Each of the opposing contact bar pairs has a plurality of external contact points and a plurality of internal contact points. The multiple external contact points are in contact with the female electrical terminal, and the multiple internal contact points are in contact with opposite sides of the male electrical terminal. Contact is established between the contact bar, the female electrical terminal, and the male electrical terminal at at least four separate points.

[0005] US 2013 / 0252474A1 discloses an electrical connector system in which an electrical connection assembly comprises a first connector including a first electrical contact surrounded by a first connector wall defining a first connector cavity. The first connector wall includes a plurality of ribs extending into the first connector cavity. A second connector is pluggable along a mating axis with the first connector and includes a second electrical contact that is electrically connected to the first electrical contact when the first connector is mated with the second connector. The second connector includes a second connector body surrounding the second electrical contact.

[0006] WO 2020 / 100 731 A1 describes a connector for engaging and disengaging a line-side connector, comprising: a terminal element comprising an electrically conductive terminal body forming a wide, flat plate shape, and a terminal protection part attached to the terminal body 20; and a housing separate from the terminal element comprising a terminal retention part that holds the terminal element. The terminal protection part includes a pair of lateral edge cover parts that longitudinally cover portions of both side faces of the terminal body. A terminal insertion recess part, into which the terminal element is inserted and fitted, is arranged on the terminal retention part.In a state where the connecting element is inserted into the connecting insertion recess part and assembled with the connecting retaining element, the side edge cover parts are attached to the connecting insertion recess part in such a way that they can come into contact with the connecting retaining element.

[0007] EP 2 795 740 B1 describes an electrical connector arrangement comprising a first connector with a first and a second contact, a second connector with a first and a second contact, a first locking contact and a second locking contact arranged in the first connector, wherein the first and the second connectors are designed to be inserted into and separated from each other along a mating axis between an unmounted position and a mounted position in order to connect the first contacts to each other, the second contacts to each other and the locking contacts to each other, wherein the second connector comprises a locking system designed to lock the first and the second connectors in an intermediate position when the first and the second connectors are separated, wherein in the intermediate position the first contacts are connected to each other.the second contacts are connected to each other and the locking contacts are separated from each other, the second connector comprising a locking system designed to secure the first and second connectors in the intermediate position.

[0008] DE 10 2015 214 284 A1 discloses an electrical connector with a vibration-resistant short-circuit bridge and an electrical plug connection. The electrical connector for connection with a complementary mating connector in one insertion direction is described. The connector housing has a receptacle in which a short-circuit bridge, held stationary in its insertion position, is received, with two short-circuit contacts accessible from outside the connector in the opposite direction to the insertion direction. Furthermore, an electrical plug connection with such an electrical connector and a mating electrical connector is described. In the described electrical connector, the short-circuit bridge is movably mounted in the receptacle with play around the insertion position.In the described electrical connector, in a plug-in position the short-circuit contacts of the short-circuit bridge are electrically and motion-transmittingly connected to the opposite short-circuit contacts of the electrical mating connector, but are mechanically decoupled from a movement of the electrical connector due to the receptacle of the short-circuit bridge being movable around the plug-in position.

[0009] US 8,298,022 B2 describes a connector and a connector assembly. The connector has a receptacle mounted in a connector housing. The connector housing has a tube surrounding the receptacle. The tube is spaced from a conductive portion of the connector so that a finger cannot be inserted between the tube and the connector. A female connector adapter can be inserted between the tube and the male connector, allowing the female connector to make contact with the conductive portion of the male connector. An insulating coating is formed by molding a resin onto a front end of the male connector to prevent impacts.

[0010] US 7,789,690 B1 describes a connector assembly with a multi-stage locking sequence, comprising a housing, a power supply contact, a locking circuit contact, a lever subassembly, and a lever lock. The lever subassembly is pivotally connected to the housing and includes a handle and a gripping end that engages the mating connector to move the housing relative to the mating connector when the handle is rotated. The handle is rotated to sequentially disengage the locking circuit contact from its matching locking contact before disengaging the power supply contact from its matching power contact.The lever lock is connected to the housing and prevents the power supply contact from being disconnected from the counter-current contact before the locking circuit contact and the counter-locking contact are disconnected, before the power supply contact is disconnected from the counter-current contact, and after the locking circuit contact has been disconnected from the counter-locking contact by blocking the rotation of the lever assembly.

[0011] The present disclosure aims to provide a first connector and a connector arrangement capable of suppressing the wear of contact points.

[0012] This subject matter is solved according to the invention by the features of the independent claims. Particular embodiments of the invention are the subject of the dependent claims.

[0013] According to one aspect, a first connector is provided which can be fixed to and detached from a second connector, and which includes one or more, in particular a plurality, first connecting members, each having pointed parts extending in a first direction, and a first connector housing for holding the one or more, in particular the plurality, first connecting members, wherein the first connector housing includes a pair of first walls, each having a pointed part extending in the first direction, wherein the first walls are connected to each other via a plurality of coupling walls, and the first walls include a first fitting section, which is to be convexly-concave fitted to, or form-fitted to, or engaged with a second fitting section provided in the second connector.and the first fitting section is brought into engagement with the second fitting section in a second direction which intersects or crosses an assembly direction of the first and second connectors when the first connector is connected or assembled with the second connector.

[0014] According to another aspect, a connector arrangement is provided which includes a first connector according to the above aspect and a second connector which can be fixed to and removed from the first connector.The second connector is removable, wherein the second connector comprises one or more, in particular a plurality, second connecting elements, an inner housing for receiving the one or more, in particular the plurality, second connecting elements, and an outer housing for at least partially receiving the inner housing, wherein the inner housing is a component separate from the outer housing, the inner housing comprises at least one second fitting section which is to be fitted convexly-concave or form-fitted to a first fitting section which is provided in the first connector, and the second fitting section is to be brought into engagement with the first fitting section in a second direction which intersects or crosses an assembly direction of the first and second connectors. According to the above, it is possible to achieve an effect of suppressing wear at contact points.

[0015] Further special embodiments are listed and described as follows: In particular, a first connector, which is fixable to and detachable from a second connector, comprises a plurality of first connecting members having pointed parts extending in a first direction, and a first connector housing for holding the plurality of first connecting members, wherein the first connector housing comprises a first wall having a pointed part extending in the first direction, the first wall comprising a first fitting section which is to be fitted convexly-concave to a second fitting section provided in the second connector, and the first fitting section being brought into engagement with the second fitting section in a second direction which intersects an assembly direction of the first and second connectors.

[0016] According to this configuration, the first connector housing is provided with the first fitting section to be convexly-concave fitted to the second fitting section, which is provided in the mating or matched second connector, and to engage with the second fitting section in the second direction, which intersects the assembly direction of the first and second connectors. The engagement of this first fitting section with the second fitting section restricts movement of the first connector housing in the second direction. Thus, even if vibration is applied to the first connector, which is assembled with the second connector, it is possible to suppress relative movement of the first connector housing with respect to the second connector in the second direction.In this way, it is possible to suppress relative movements of the first connecting elements, which are held in the first connector housing, with respect to the second connecting elements, which are provided in the second connector. As a result, wear at the contact points between the first and second connecting elements can be effectively suppressed.

[0017] Furthermore, in particular, the first fitting section includes a first projection or extension which extends from the first wall along a third direction which intersects or crosses the first and second directions and projects towards the first connecting member, the first connecting member has a first surface which is directed towards the first projection in the third direction, and a shortest distance L1 between a tip of the first projection and the first surface of the first connecting member in the third direction is a first distance.

[0018] According to this configuration, the shortest distance L1 between the tip of the first projection or extension extending in the third direction from the first wall and the first surface of the first connecting member is set or defined as the first distance. Here, the first distance is a distance in the range of approximately 3 mm and / or more and approximately 15 mm or less. Preferably, the first distance is a distance in the range of approximately 6 mm or more and / or approximately 12 mm or less, more preferably a distance in the range of approximately 6 mm or more and / or 9 mm or less. By setting or defining the shortest distance L1 as the first distance, it is possible to prevent a worker's finger from entering a gap or space between the tip of the first projection and the first surface of the first connecting member.In this way, it can be suppressed that the worker's finger contacts the first connecting element through the distance or free space between the tip of the first projection and the first surface of the first connecting element.

[0019] Here, "directed or oriented towards each other" in this description means that surfaces or elements are positioned in front of each other. This includes not only cases where the two are perfectly aligned, but also cases where they are partially aligned. Furthermore, "directed or oriented towards each other" in this description also includes cases where another element is present between the two parts, as well as cases where nothing is present between them.

[0020] Furthermore, the first surface of the first connector is a connection surface that is to be connected to a second connector provided in the second connector. According to this configuration, it is possible to prevent a worker's finger from entering a gap between the tip of the first projection and the connection surface of the first connector. In this way, it is possible to prevent the worker's finger from contacting the connection surface of the first connector through the gap between the tip of the first projection and the connection surface of the first connector.

[0021] Furthermore, the first connector has a second surface which is provided on one side opposite the first surface in the third direction; the first connector housing includes a second wall which has a pointed part extending in the first direction; the second wall is provided on one side substantially opposite the first wall transversely across the first connector in the third direction; the second wall has a third surface which is directed towards the second surface of the first connector in the third direction; and a shortest distance L2 between the third surface of the second wall and the second surface of the first connector in the third direction and the shortest distance L1 satisfy a relationship of L2 ≤ L1. According to this configuration, the following applies:The shortest distance L2 between the third surface of the second wall and the second surface of the first connecting element is set to be equal to or shorter than the shortest distance L1, i.e., equal to or shorter than the first distance. This prevents a worker's finger from entering a gap between the third surface of the second wall and the second surface of the first connecting element. It also prevents the worker's finger from contacting the first connecting element through the gap between the third surface of the second wall and the second surface of the first connecting element.

[0022] Furthermore, the majority of first connection members are arranged essentially side by side along the third direction, and the pair of first walls is arranged between the majority of first connection members in the third direction. According to this configuration, the first fitting section is arranged on the first wall located between the majority of first connection members. In this way, the first fitting section can be located close to the majority of first connection members. Therefore, relative movements of the first connection members located close to the first fitting section can be suitably suppressed.

[0023] Furthermore, the assembly direction is specifically a direction parallel to the first direction, and the first connector housing includes a protective section for covering the first connecting members, except for parts in the second direction in directions orthogonal to the first direction, a first opening which is open in the first direction in the protective section, and a second opening which is open in the second direction in the protective section. According to this configuration, the second opening is open in the second direction in which the first and second fitting sections engage. In other words, the first and second fitting sections engage with each other in the second direction in which the second opening is open.In the case of including the second opening, which is open in the second direction and intersects the assembly direction of the first and second connectors, the first connector housing moves slightly relative to the second connector housing in the second direction in which the second opening is open when the second connector is assembled with the first connector. Accordingly, the first fitting section is designed to engage with the second fitting section in the second direction in the configuration described above, thus appropriately suppressing any relative movement of the first connector housing relative to the second connector in the second direction.

[0024] Furthermore, the protective section includes, in particular, a pair of side walls that form the second opening. One of the first walls of this pair is also a side wall, and the first projection extends from an inner surface of one of the side walls towards the first connecting member. According to this configuration, the first fitting section is located on the inner surface of the side wall that forms the protective section and surrounds the outer circumferences of the first connecting members. In this way, the first fitting section can be positioned close to the first connecting members. Therefore, relative movements of the first connecting members located close to the first fitting section can be effectively suppressed.

[0025] Furthermore, the majority of first connecting elements, in particular, includes two first connecting elements essentially adjoining or adjacent to each other in the third direction; the protective section includes a first protective section for protecting one of the two first connecting elements and a second protective section for protecting the other of the two first connecting elements; the first fitting section includes the first projection provided on the first protective section and a second projection provided on the second protective section; the first projection projects from an inner surface of one of the first walls of the pair of first walls, which is provided between the two first connecting elements in the third direction, towards the first first connecting element of the first protective section.The second projection extends towards the other first connecting member from an inner surface of a side wall, which is at least partially located between the two first connecting members in the third direction, and from the second protective section. According to this configuration, the first and second protective sections are provided for the individual protection of the two first connecting members.

[0026] Furthermore, the first fitting section includes, in particular, the first projection or extension provided on the first protective section and the second projection or extension provided on the second protective section. In other words, the first fitting sections are provided on both the first and the second protective section. Thus, the first fitting sections can be positioned close to the two first connecting elements. Therefore, relative movements of the two first connecting elements can be effectively suppressed.

[0027] Furthermore, the first fitting section includes, in particular, the first projection and a first recess or indentation, which is recessed or set off from a projecting end surface of the first projection. The first projection has at least one first inclined surface, which is inclined relative to a plane orthogonally to the assembly direction, and the first inclined surface guides at least one third projection of the second fitting section into the first recess when the second connector is assembled with the first connector. According to this configuration, the first projection has the first inclined surface for guiding the third projection of the second fitting section of the second connector into the first recess or indentation when the second connector is assembled with the first connector.In this way, the first and second fitting sections can be easily fitted convexly-concave when the second connector is assembled with the first. This allows the second connector to be easily assembled with the first.

[0028] Furthermore, the first recess or indentation has at least one second inclined surface, which is inclined orthogonally to the assembly direction relative to the plane, and this second inclined surface guides the third projection of the second fitting section into the first recess when the second connector is assembled with the first connector. According to this configuration, the first recess has the second inclined surface for guiding the third projection of the second fitting section of the second connector into the first recess when the second connector is assembled with the first connector. In this way, the first and second fitting sections can be easily fitted convexly-concave when the second connector is assembled with the first connector.

[0029] Furthermore, the first connector housing includes, in particular, at least one base section for holding the base end parts of the first connecting members, the first wall projecting from the base section in the first direction, and at least one reinforcing section coupling a base end part of the first wall and the base section. According to this configuration, the base section of the first connector housing and the base end part of the first wall are coupled by the reinforcing section. This prevents the first wall from vibrating when vibration is applied to the first connector, compared to a configuration that does not include the reinforcing section. In this way, relative movement of the first connector housing and, consequently, relative movement of the first connecting members can be suppressed.

[0030] According to another particular embodiment, a second connector, which is fixable to and detachable from a first connector, comprises a plurality of second connecting elements, an inner housing for at least partially receiving the plurality of second connecting elements, and an outer housing for receiving the inner housing, wherein the inner housing is a component separate from the outer housing, the inner housing comprises a second fitting section which is to be fitted convexly-concave to a first fitting section which is provided in the first connector, and the second fitting section is engaged with the first fitting section in a second direction which intersects an assembly direction of the first and second connectors.

[0031] According to this configuration, the inner housing is provided with the second fitting section to be convexly-concave fitted to the first fitting section, which is provided in the mating or tuned first connector, and to engage with the first fitting section in the second direction, which intersects the assembly direction of the first and second connectors. The engagement of this second fitting section with the first fitting section restricts movement of the inner housing in the second direction. Thus, even if oscillation or vibration is applied to the second connector, which is assembled with the first connector, it is possible to suppress relative movement of the inner housing with respect to the first connector in the second direction.In this way, the movement of the second connecting elements, which are housed in the inner casing, relative to the first connecting elements, which are provided in the first connector, can be suppressed. As a result, wear at the contact points between the first and second connecting elements can be effectively reduced.

[0032] In particular, the inner housing comprises a base section and at least one connector-receiving section or connector-receiving section extending from the base section. The connector-receiving section at least partially receives one or more second connectors inside, and the second fitting section is provided on an outer surface of the connector-receiving section. According to this configuration, the second fitting section on the outer surface of the connector-receiving section or connector-receiving section is designed to receive the second connectors inside. In this way, the second fitting section can be located close to the second connectors. Therefore, relative movements of the second connectors located close to the second fitting section can be suitably suppressed.

[0033] Furthermore, the majority of second connection elements are essentially arranged side by side or adjacent to each other along a third direction, which intersects or crosses the second direction; if the connection-receiving section includes a first connection-receiving section and a second connection-receiving section, which is located away from the first connection-receiving section in the third direction; if the first connection-receiving section has a first facing surface, which is directed towards the second connection-receiving section in the third direction.In this configuration, the second fitting section has a second facing surface directed towards the first facing surface, and the second fitting section includes a third projection extending substantially towards the second facing surface from the first facing surface, and a fourth projection extending towards the first facing surface from the second facing surface. According to this configuration, the second fitting section includes the third projection or extension provided on the first facing surface of the first fitting section and the fourth projection or extension provided on the second facing surface of the second fitting section.In other words, the second fitting sections are provided on both the first and the second connecting section. Thus, the second fitting sections can be located near the second connecting member that is received in the first connecting section, and near the second connecting member that is received in the second connecting section. Therefore, relative movements of the second connecting members located near the second fitting sections can be suitably suppressed. Furthermore, the third and fourth projections are provided to be oriented towards each other in the third direction. Thus, when the second connector is assembled with the first connector, the first fitting section of the first connector is located between the third and fourth projections in the third direction. Therefore,The third and fourth projections of the second fitting sections are fitted convexly-concave to the first fitting section from both sides in the third direction. In this way, relative movement of the inner housing with respect to the first connector can be more effectively suppressed, and relative movements of the second connecting members can also be more effectively suppressed.

[0034] Furthermore, the second fitting section includes, in particular, the third projection and a second recess or indentation, which is recessed or set off from a projecting end surface of the third projection in the direction of the first facing surface. The third projection has at least one third inclined surface, which is inclined orthogonally to the assembly direction relative to a plane, and the third inclined surface guides a first projection of the first fitting section into the second recess when the second connector is assembled with the first connector. According to this configuration, the third projection has the third inclined surface for guiding the first projection of the first fitting section of the first connector into the second recess or indentation when the second connector is assembled with the first connector.In this way, when the second connector is assembled with the first connector, the first and second fitting sections can be fitted together in a slightly convex-concave manner. This allows the second connector to be easily assembled with the first connector.

[0035] Furthermore, the second recess has at least a fourth inclined surface, which is inclined orthogonally to the assembly direction relative to the plane, and this fourth inclined surface guides the first projection of the first fitting section into the second recess when the second connector is assembled with the first connector. According to this configuration, the first recess has the fourth inclined surface for guiding the first projection of the first fitting section of the first connector into the second recess when the second connector is assembled with the first connector. Thus, when the second connector is assembled with the first connector, the first and second fitting sections can be easily fitted in a convex-concave manner. In this way, the second connector can be easily assembled with the first connector.

[0036] Furthermore, the second connector includes an inner link that is mounted on the outer housing, and this inner link supports the inner housing within the outer housing. According to this configuration, the inner housing is supported by the inner link within the outer housing. In this way, even when vibration is applied to the second connector, vibration of the inner housing within the outer housing can be suppressed, compared to a configuration that does not include the inner link. Thus, relative movement of the inner housing can be suppressed, and consequently, relative movements of the second connector link can also be suppressed.

[0037] Furthermore, in particular the first and second connection-receiving sections are formed integrally or in one piece by the base section, and the inner link supports the inner housing by contacting the base section.

[0038] According to this configuration, the first and second connection-receiving sections are integrally formed, or rather, formed in one piece, by the base section. This reduces the number of components compared to cases where the first and second connection-receiving sections are configured or constructed as separate components. Furthermore, both the first and second connection-receiving sections can be supported by the contact of the inner link with the base section. This simplifies the structure of the inner link compared to cases where separate structures are provided for supporting the first and second connection-receiving sections.

[0039] According to another particular embodiment, a connector arrangement comprises a first connector and a second connector, which can be fixed to and removed from the first connector.is removable, wherein the first connector includes one or more, in particular a plurality, first connecting members having pointed parts extending in a first direction, and a first connector housing for holding or positioning the one or more, in particular the plurality, of first connecting members, the first connector housing includes at least one first wall having a pointed part extending substantially in the first direction, the first wall includes at least one first fitting section which is to be fitted or form-fitted convexly-concave to a second fitting section provided in the second connector, and the first fitting section engages or can be engaged with the second fitting section in a second direction which intersects or crosses an assembly direction of the first and second connector.

[0040] According to this configuration, the first connector housing is provided with the first fitting section, which is designed to fit convexly-concavely onto the second fitting section provided in the second connector and engage with the second fitting section in the second direction, which intersects the assembly direction of the first and second connectors. The engagement of this first fitting section with the second fitting section restricts movement of the first connector housing in the second direction. Thus, even if vibration is applied to the first connector, which is assembled with the second connector, it is possible to suppress relative movement of the first connector housing with respect to the second connector in the second direction.In this way, it is possible to suppress relative movements of the first connecting elements, which are held in the first connector housing, with respect to the second connecting elements, which are provided in the second connector. As a result, wear at the contact points between the first and second connecting elements can be effectively suppressed.

(Total configuration of the connector arrangement 10)

[0043] As this is in Fig. 1 and Fig. As shown in Figure 2, a connector arrangement 10 includes a first connector 20 and a second connector 70, which can be fixed to and detached from the first connector 20.

[0044] Specifically, the connector arrangement 10 is to be provided in a vehicle. For example, the vehicle contains a plurality of devices located within the vehicle, such as a high-voltage battery and an inverter. The plurality of devices located within the vehicle are or will be connected or connected via wiring or a wiring harness. The connector arrangement 10 is provided, for example, at the end components of the device located within the vehicle and the wiring.

[0045] The first and second connectors 20, 70 are to be assembled together along an assembly direction D1. It should be noted that the assembly direction D1 indicates a relative assembly direction of the second connector 70 with the first connector 20, and that the first connector 20 is not restricted to a fixed side. Furthermore, a vertical direction in any figure does not necessarily indicate the positions or orientations of the first and second connectors 20, 70 during use. (Configuration of the first connector 20)

[0046] As this is in Fig. 3 and Fig. As shown in Figure 4, the first connector 20 includes one or more (two in this embodiment) first connecting element(s) 21, a first connector housing 30 for holding and / or positioning the first connecting elements 21, and in particular one or more (two in this embodiment) sliding elements 60. The sliding elements 60 are held in the first connector housing 30. (Configuration of the first connection elements 21)

[0047] As this is in Fig. As shown in Figure 5, each first connecting element 21 includes at least one first connection 22 (which is made in particular of a conductive material, such as a metal) and a protective element 25.

[0048] The first connection 22 comprises a base section 23 and a connecting section 24, which extends substantially in a first direction X1 from the base section 23. A tip portion of the connecting section 24, i.e., a tip portion of the first connection 22, extends substantially in the first direction X1 from the base section 23. In this embodiment, the extending direction of the tip portion of the first connection 22 is referred to as the first direction X1, and a direction opposite to the first direction X1 is referred to as the first opposite direction X2. It should be noted that the first direction X1 and the first opposite direction X2 of this embodiment are directions parallel to the assembly direction D1.

[0049] The first connection 22, for example, is a single component in which the base section 23 and the connecting section 24 are formed continuously and integrally or in one piece.

[0050] The first connection 22 is formed, for example, by pressing a metal plate material made of copper, a copper alloy, aluminum, an aluminum alloy or the like.

[0051] As this is in Fig. As shown in Figure 3, the connecting section 24 is essentially in the form of a flat plate. Specifically, an axial direction of the connecting section 24 extends essentially along the first direction X1. A lateral direction of the connecting section 24 extends essentially along a second direction Y1 orthogonal to the first direction Z1. A thickness direction of the connecting section 24 extends essentially along a third direction Z1, which intersects (or is orthogonal to) both the first and second directions X1, Y1. One end surface in the lateral direction of the connecting section 24 is oriented essentially in the second direction Y1, and the other end surface in the lateral direction of the connecting section 24 is oriented essentially in a second, opposite direction Y2, which is a direction opposite to the second direction Y1.One end surface in the thickness direction of the connecting section 24 is essentially directed in the third direction Z1, and the other end surface in the thickness direction of the connecting section 24 is essentially directed in a third opposite direction Z2, which is a direction opposite to the third direction Z1.

[0052] Of the two end surfaces in the thickness direction of the connecting section 24, one end surface is a connecting surface 24A, which is connected to a second connecting member 71 (see Fig. 1) of the second connector 70 is to be connected, and the other end surface is a non-connecting surface 24B, which is not to be connected to the second connector 71.

[0053] The connecting surface 24A is formed, in particular, on a substantially flat surface extending parallel to the first direction X1. The non-connecting surface 24B is formed, in particular, on a substantially flat surface extending parallel to the first direction Z1. It should be noted that the protective element 25 in one of the two first connecting elements 21 is not in Fig. 3 is shown.

[0054] As this is in Fig. As shown in Figure 5, the first two terminals 22 are essentially arranged side by side along the third direction Z1. The first two terminals 22 are, or will be, arranged such that the two connection surfaces 24A are essentially oriented towards each other in the third direction Z1.

[0055] The protective element 25 is, or is, mounted, arranged, provided, or made available, particularly on the tip portion of the connecting section 24. The protective element 25 is designed to at least partially cover the tip surface of the connecting section 24. The protective element 25 is, for example, made of an insulating resin or plastic material. (Configuration of the first connector housing 30)

[0056] As this is in Fig. As shown in Figure 3, the first connector housing 30 includes, for example, a base section 31, a circumferential wall section 32 extending substantially in the first direction X1 from the base section 31, and / or a protective section 40 extending substantially in the first direction X1 from the base section 31, particularly within the circumferential wall section 32. The first connector housing 30 is, for example, a single component in which the base section 31, the circumferential wall section 32, and / or the protective section 40 are integrally or integrally formed. The first connector housing 30 is, for example, made of an insulating resin or plastic material. (Configuration of base section 31)

[0057] The base section 31 holds the one or more base section(s) 23 (see Fig. 5) of one or more first connections (connections) 22. The base section 31 includes, for example, a fixing or securing section 31A, which projects further outwards than the circumferential wall section 32. The fixing or securing section 31A is to be fixed, for example, to a housing of the device located in the vehicle (not illustrated). (Configuration of perimeter wall section 32)

[0058] The circumferential wall section 32 is specifically designed in a partially cut ring shape. For example, the circumferential wall section 32 is essentially in the form of a rectangular or right-angled ring extending in the first direction X1. The circumferential wall section 32 is formed, for example, by cutting a side in the first direction X1 and a surface in the second direction Y1 of the right-angled ring. The circumferential wall section 32 jointly surrounds the outer circumferences of the two first connecting members 21.

[0059] Here, "ring" in this description means a ring-like structure that is continuous without any interruption, i.e., an endless structure with a starting point and an endpoint that coincide. Furthermore, "ring" in this description means any arbitrary closed shape or form that has an outer border or edge connected by straight and / or curved lines, such as a circular ring with a circular outer border, a ring with an elliptical or oval outer border, a polygonal ring with a polygonal outer border, or a ring with a rounded polygonal outer border.The "ring" is a shape that has a through-hole in a top view, and the shape of an outer rim or edge and an inner circumferential shape of the through-hole may be the same or different. The "ring" may be a ring that has a specific (predetermined or determinable) length along an axial direction along which a central axis, passing through a center of the through-hole, extends, and this length is not essential. Furthermore, in this description, the "ring" is to be considered only as a ring in its entirety and may be a ring that has a cut, a slot, or the like in one part, such as a C-shape. (Configuration of the protective section 40)

[0060] The protective section 40 includes one or more, in particular two, protective sections 40A, 40B for (in particular individual) protection of one or more (e.g. two) first connection element(s) 21. Each protective section 40A, 40B substantially surrounds the outer perimeter of each first connection element 21.

[0061] The protective section 40A essentially surrounds the outer circumference of the first connecting member 21, which is arranged on one side in the third direction Z1, i.e. the connecting member 21 on a left side in Fig. 3, of the first two connecting members 21.

[0062] The protective section 40B essentially surrounds the outer circumference of the first connecting member 21, which is arranged on one side in the third opposite direction Z2, i.e. the connecting member 21 on a right side in Fig. 3, of the first two connecting members 21.

[0063] Each protective section 40A, 40B is in the form of a partially cut ring. Each protective section 40A, 40B is, for example, in the form of a rectangular or right-angled ring extending in the first direction X1.

[0064] Each protective section 40A, 40B is configured to essentially cover the first connecting member 21, with the exception of a portion in the second direction Y1, in directions orthogonal to the first direction X1. Each protective section 40A, 40B is formed by cutting a side in the first direction X1 of a surface in the second direction Y1 of the right-angled ring. By this configuration, each protective section 40A, 40B includes, in particular, a first opening 41 that opens in the first direction X1 and a second opening 42 that is open in the second direction Y1. The tip of each protective section 40A, 40B projects further in the first direction X1 than the tip of the first connecting member 21.

[0065] Each protective section 40A, 40B comprises one or more, in particular a pair, side walls 43, 44, a lower wall 45, and / or an upper wall 46. The side walls 43, 44 are substantially oriented towards each other in the third direction Z1. The inner surface of side wall 43 is substantially oriented towards the connecting surface 24A of the connecting section 24. The inner surface of side wall 44 is substantially oriented towards the non-connecting surface 24B of the connecting section 24. The lower wall 45 is a circumferential wall on the side in the second direction Y1 in each protective section 40A, 40B in the form of a right-angled ring. The upper wall 46 is a circumferential wall on the side in the second opposite direction Y2 in each protective section 40A, 40B, in particular substantially in the form of a right-angled ring. The second opening 42 is provided in the lower wall 45.The second opening 42 is formed by cutting a side in the first direction X1 of the lower wall 45. The second opening 42 is, in particular, essentially surrounded by the pair of side walls 43, 44 and the lower wall 45.

[0066] The two protective sections 40A, 40B are arranged essentially side by side or adjacent to each other along the third direction Z1. In this embodiment, both the side wall 43 of protective section 40A and the side wall 43 of protective section 40B are located essentially between the two first connecting members 21 in the third direction Z1. The side wall 43 of protective section 40A and the side wall 43 of protective section 40B are formed, for example, integrally or in one piece by a coupling wall 47. (Configuration of the first fitting sections 50)

[0067] As this is in Fig. As shown in Figure 6, the first connector 20 includes, for example, one or more first fitting section(s) 50. The one or more first fitting section(s) 50 is / are designed to fit convexly-concavely to one or more respective second fitting section(s) 100 of the second connector 70. The first fitting section(s) 50 is / are to engage with the second fitting section(s) 100 in a direction that intersects the assembly direction D1 of the first and second connectors 20, 70. The first fitting section(s) 50 is / are, for example, engaged with the second fitting section(s) 100 in the second direction Y1, which is an opening direction of the second opening 42. In other words,The first fitting section 50, provided in the first connector 20, engages with the second fitting section 100, provided in the second connector 70, in a direction (Y1 in the example shown) that intersects the assembly direction D1, when the first and second connectors 20, 70 are properly aligned or joined. Specifically, a contour of the first fitting section (50) substantially coincides with or corresponds to a contour of the second fitting section (100). Accordingly, the first fitting section (50) and the second fitting section (100) interlock when the first and second connectors 20, 70 are properly joined.

[0068] The one or more first fitting section(s) 50 is / are provided in the first connector housing 30. The one or more first fitting section(s) 50 is / are provided, for example, on the perimeter wall(s) of the protective section(s) 40A, 40B.

[0069] The one or more first fitting section(s) 50 is / are, for example, on the inner surface(s) of the side wall(s) 43, which is / are directed essentially towards the connecting surface(s) 24A of the first connection(s) 22, from the circumferential wall(s) of the protective section(s) 40A, 40B.

[0070] The first fitting sections 50 of this embodiment are specifically provided on the inner surface of the side wall 43 of one protective section 40A and on the inner surface of the side wall 43 of the other protective section 40B. That is, the first connector housing 30 of this embodiment includes, in particular, two first fitting sections 50.

[0071] As this is in Fig. As shown in Figure 4, each first fitting section 50 includes one or more projections 51 (seven in this embodiment) and one or more recesses 52 (six in this embodiment). In each first fitting section 50, the seven projections 51 and the six recesses 52 are arranged alternately, substantially side by side, in the second direction Y1.

[0072] As this is in Fig. As shown in Figure 7, each projection 51 projects substantially in the direction of the connecting surface 24A of the first terminal 22 from the bottom surface of each depression 52. For example, each projection 51 projects substantially to extend along the third direction Z1 or the third opposite direction Z2 from the bottom surface of each depression 52. For example, each projection 51 projects substantially to extend along the third direction Z1 orthogonally to the second direction Y1 in which the second opening 42 is open.

[0073] In this embodiment, the projections 51 (first projection) which are provided on the side wall 43 of the protective section 40A and the projections 51 (second projection) which are provided on the side wall 43 of the protective section 40B project, in particular in directions substantially opposite to each other.

[0074] Specifically, the projections 51, which are provided on the side wall 43 of the protective section 40A, project substantially in the third direction Z1 from the inner surface of the side wall 43, and the projections 51, which are provided on the side wall 43 of the protective section 40B, project substantially in the third opposite direction Z2 from the inner surface of the side wall 43.

[0075] Each projection 51 extends substantially along the first opposite direction X2, in particular from a tip portion of the side wall 43. An axial direction of each projection 51, in which a central or midline axis of each projection 51 extends, is substantially parallel to the first direction X1.

[0076] Specifically, each projection 51 has a projecting end surface 51A, a pair of side surfaces 51B, and an end surface 51C. Each projecting end surface 51A is located at the position furthest from the bottom surface of the recess 52 in the third direction Z1 of the end surfaces of each projection 51. In other words, each projecting end surface 51A is located at the position closest to the first terminal 22 of the end surfaces of each projection 51.

[0077] The (in particular each) projecting end surface 51A is oriented substantially towards the first terminal 22. The projecting end surface 51A widens, in particular in the first direction X1 and / or in the second direction Y1. The (in particular each) side surface 51B widens, in particular in the first direction X1 and / or in the third direction Z1. Each side surface 51B forms the inner side surface of the recess 52.

[0078] The end surface 51C is a surface in the first direction X1 in the projection 51. The end surface 51C is designed, for example, to be flush with the tip surface of the side wall 43. Each end surface 51C and the tip surface of the side wall 43 are connected to the second connector 70 (see Fig. 6) directed in the first direction X1.

[0079] The (in particular each) recess 52 is designed to be recessed or set off from the projecting end surface 51A of each projection 51. The (in particular each) recess 52 extends substantially along the first opposite direction X2 from the tip surface of the side wall 43.

[0080] The bottom surface of each recess 52 is, for example, substantially directed towards the connection surface 24A of the first terminal 22. A tip portion of each recess 52, i.e., an end portion in the first direction X1 of each recess 52, is, in particular, for example, open in the first direction X1 parallel to the assembly direction D1.

[0081] Accordingly, when the first and second connectors 20, 70 are properly fitted together, the projection(s) 51 on the side wall 43 is (in particular completely) inserted into (a) recess(s) 102 of the second connector 70, which is described below, and / or a projection(s) 101 of the second connector 70, which is described below, is (in particular completely) inserted into the recess(s) 52, so that as a result the one or more first fitting section(s) 50 are convexly-concave fitted to or form-fitted with the one or more respective second fitting section(s) 100 of the second connector 70, or interlock with or engage with each other.

[0082] As this is in Fig. As shown in Figure 8, a tip portion of each projection 51, i.e., an end portion in the first direction X1 of each projection 51, includes in particular at least one guiding section 53, which is substantially formed in a tapered shape. The guiding section 53 is, for example, configured to become narrower towards the end surface 51C of the projection 51. The guiding section 53 is provided on or near a front face in the assembly direction D1. The guiding section 53 has in particular at least one inclined surface 54, which is provided on the projecting end surface 51A, and / or one or more inclined surface(s) 55, which are provided on the respective side surfaces 51B.

[0083] The inclined surface 54 is provided, in particular, on the projecting end surface 51A on the tip portion of the projection 51. The inclined surface 54 is, in particular, substantially inclined to approach the central axis of the projection 51 in the direction of the end surface 51C of the projection 51. The inclined surface 54 is substantially inclined relative to a plane orthogonally to the assembly direction D1.

[0084] Furthermore, the inclined surface 54 is inclined, in particular, substantially relative to a plane parallel to the assembly direction D1. The inclined surface 54 is formed, for example, by chamfering a corner section between the end surface 51C and the projecting end surface 51A. The chamfer can be an R-chamfer or a C-chamfer. The inclined surface 54 of this embodiment is formed by applying a C-chamfer to the corner section between the end surface 51C and the projecting end surface 51A.

[0085] The inclined surface 55 is provided on the side surface 51B at or near the tip portion of the projection 51. The inclined surface 55 is, in particular, substantially inclined to approach the central axis of the projection 51 in the direction of the end surface 51C of the projection 51. The inclined surface 55 is substantially inclined relative to a plane orthogonal to the assembly direction D1.

[0086] Furthermore, the inclined surface 55 is inclined, in particular, substantially relative to a plane parallel to the assembly direction D1. The inclined surface 55 is formed to widen an opening width along the second direction Y1 of the recess 52 in the tip portion of the recess 52. The inclined surface 55 is formed, for example, by applying an R-chamfer or C-chamfer to the corner portion between the end surface 51C and the side surface 51B. The inclined surface 55 of this embodiment is formed by applying a C-chamfer to the corner portion between the end surface 51C and the side surface 51B.

[0087] The bottom surface of each recess 52 has, in particular, an inclined surface 56, which is provided in the apex of the recess 52. The inclined surface 56 is, in particular, substantially inclined to approach the coupling wall 47 in the direction of the apex surface of the side wall 43. The inclined surface 56 is, or is, substantially formed to widen an opening width along the third direction Z1 of the recess 52 in the apex of the recess 52. The inclined surface 56 is inclined orthogonally to the assembly direction D1 relative to a plane.

[0088] Furthermore, the inclined surface 56 is inclined, in particular, substantially relative to a plane parallel to the assembly direction D1. The inclined surface 56 is formed, for example, by applying an R-chamfer or a C-chamfer to a corner portion between the tip surface of the side wall 43 and the bottom surface of the recess 52. The inclined surface 56 of this embodiment is formed by applying a C-chamfer to the corner portion between the tip surface of the side wall 43 and the bottom surface of the recess 52.

[0089] The leading or guiding section 53, i.e. the inclined surface(s) 54, 55 and / or 56, in particular has a function of guiding a projection 101 (see Fig. 12) of the second fitting section 100 into the recess 52 when the second connector 70 is assembled with the first connector 20.

[0090] As this is in Fig. As shown in Figure 5, a shortest distance L1 between the projecting end surface 51A of the projection 51 and the connecting surface 24A of the first connection 22 is set or defined as a first distance in a projecting direction of the projection 51 towards the first connection 22, in particular in the third direction Z1 or the third opposite direction Z2. Here, the first distance is in particular a distance in the range of approximately 3 mm or more and / or 15 mm or less. In other words, the shortest distance L1 between the projecting end surface 51A and the connecting surface 24A is set or defined, for example, to a distance in the range of approximately 3 mm or more and approximately 15 mm or less in a cross-section which includes the projecting end surface 51A and the connecting surface 24A and is normal to a central axis of the projecting section 40. It should be noted thatIt should be noted that the first distance is preferably in the range of about 6 mm or more and / or about 12 mm or less, more preferably in the range of about 6 mm or more and / or 9 mm or less. By setting or defining the shortest distance L1 as the first distance in this way, it is possible to prevent a worker's finger from entering a gap or space between the projection 51 and the first terminal 22. In this way, it is suitable to prevent the worker's finger from contacting the connection surface 24A of the first terminal 22. It should be noted that the shortest distance L1 is set or will be set to such a distance that the second terminal 71 (see . Fig. 1), which is provided in the second connector 70, can be used.

[0091] Furthermore, in the third direction Z1, a shortest distance L2 between the inner surface (third surface) of the side wall 44 and the non-connecting surface 24B (second surface) of the first connection 22 is set or determined, in particular to a distance equal to or shorter than the shortest distance L1 (L2 ≤ L1). In other words, the shortest distance L2 between the inner surface of the side wall 44 and the non-connecting surface 24B is set or determined, in particular to a distance equal to or shorter than the shortest distance L1 in the cross-section that includes the projecting end surface 51A and the connecting surface 24A and is perpendicular to the central axis of the projecting section 40. By setting or determining this distance, the shortest distance L2 between the inner surface of the side wall 44 and the non-connecting surface 24B is set or determined, in particular to a distance equal to or shorter than the shortest distance L1 in the cross-section that includes the projecting end surface 51A and the connecting surface 24A and is perpendicular to the central axis of the projecting section 40.By setting the shortest distance L2 in this way, it is suitable to prevent a worker's finger from entering a gap between the inner surface of the side wall 44 and the first connection 22. This also suitablely prevents the worker's finger from contacting the non-connecting surface 24B of the first connection 22. The shortest distance L2 of this embodiment is shorter than the shortest distance L1. That is, the first connection element 21 is located closer to the side wall 44, from the side walls 43, 44, in the third direction Z1 inside the protective section 40.

[0092] As this is in Fig. As shown in Figure 3, the first connector housing 30 specifically includes one or more reinforcing section(s) 33, which couple(s) in particular the side walls 43, which have the first fitting sections 50, and the base section 31. The reinforcing section 33 is provided inside the (in particular each) protective section 40A, 40B.

[0093] The reinforcing section 33, for example, couples a base end part of the side wall 43, i.e., an end part in the first opposite direction X2 of the side wall 43, and the base section 31, which is exposed in the protective section 40A, 40B.

[0094] The reinforcing section 33 extends essentially in the second direction Y1. The reinforcing section 33 is not, and will not be, coupled to the lower wall 45 and the upper wall 46, for example. As shown in Fig. 5 and Fig. As shown in Figure 7, the reinforcing section 33 extends in the first direction X1 from the base section 31.

[0095] The reinforcing section 33 extends in particular from the base section 31 to an intermediate position in a longitudinal direction of the side wall 43 along the first direction X1. The base section 33 has a specific (predetermined or determinable) thickness in the third direction Z1.

[0096] The reinforcing section 33 integrates in particular the base end part of the side wall 43 and the base section 31. By providing this reinforcing section 33, the rigidity or stiffness of the side wall 43 can be increased. (Configuration of the sliding links 60)

[0097] As this is in Fig. As shown in Figure 3, the (in particular each) sliding or sliding element 60 is mounted or arranged in the (in particular each) protective section 40A, 40B.

[0098] The (especially each) sliding element 60 is from a closing position (see Fig. 1) for substantially closing the second opening 42 to an opening position (see Fig. 3) Displaceable or slidable in the first opposite direction X2. Here, the closing position for closing the second opening 42 only needs to be a position where the second opening 42 can be closed to such an extent that a finger cannot reach the first connection 22 through the second opening 42, and the sliding element 60 does not necessarily have to seal the second opening 42 at the closing position. Furthermore, the opening position is a position for opening the second opening 42.

[0099] The sliding element 60, for example, is made of an insulating resin or plastic material. (Configuration of the second connector 70)

[0100] As this is in Fig. As shown in Figure 1, the second connector 70 includes one or more (two in this embodiment) second connecting element(s) 71, which is / are made of a conductive material, such as a metal, and a second connector housing 80 for holding or positioning the second connecting element(s) 71.

[0101] In this embodiment, two connecting members 71 are held in the second connector housing 80, while they are arranged essentially along the third direction Z1.

[0102] The second connector housing 80 can be fixed to and detached from the first connector housing 30. It should be noted that directions, including the third direction Z1, in the second connector 70 are based on a state where the second connector 70 is connected to the first connector 20. (Configuration of the second connection members 71)

[0103] A tip portion of every second terminal 71 extends substantially in the second, opposite direction Y2. The second terminal 71 is formed, for example, by pressing a metal plate material made of copper, a copper alloy, aluminum, an aluminum alloy, or the like.

[0104] As this is in Fig. As shown in Figure 9, the plurality of second connection elements 71 are provided to correspond to the plurality of first connections 22. A tip portion of each second connection element 71 includes a connecting section 72, which is to be connected to the connection surface 24A of each first connection 22. The connecting section 72 of each second connection element 71 contacts the connection surface 24A of the first connection 22 and is electrically connected to it when the second connector 70 is assembled with the first connector 20.

[0105] The second connecting members 71 are specifically arranged to pass through the second openings 42 of the protective sections 40A, 40B when the second connector 70 is connected to the first connector 20. (Configuration of the second connector housing 80)

[0106] As this is in Fig. As shown in Figure 10, the second connector housing 80 includes an inner housing 81 for at least partially receiving one or more second connecting elements 71 and an outer housing 110 for at least partially covering the inner housing 81. The inner housing 81 and the outer housing 110 are separate components. (Configuration of the inner case 81)

[0107] The inner housing 81 includes, for example, a base section 82 and / or a connection-receiving section 90, which projects essentially in the second, opposite direction Y2, particularly from the base section 82. The inner housing 81 is made, for example, of an insulating resin or plastic material.

[0108] As this is in Fig. As shown in Figure 11, the base section 82 is provided, in particular, on an end part in the second direction Y1 of the inner housing 81. The base section 82 is, in particular, essentially formed in a ring shape.

[0109] The base section 82 includes, for example, one or more through-holes 82X through which one or more wires 75, which are to be electrically connected to the respective second connecting element(s) 71, are passed. Specifically, the base section 82 includes two through-holes 82X through which two wires 75 are passed individually. Each through-hole 82X passes through the base section 82 in the second direction Y1.

[0110] Specifically, the base section 82 includes, in particular, a partition 83 which at least partially separates or divides the two passage holes 82X. The partition 83 is provided between the two passage holes 82X in the third direction Z1. The partition 83 is provided, for example, in a central part in the third direction Z1 of the base section 82. The partition 83 extends, for example, substantially over the entire length of the base section 82 in the second direction Y1.

[0111] As this is in Fig. As shown in Figure 12, the single-connection section 90 accommodates the two second connection elements 71. The single-connection section 90 includes, for example, two single-connection sections 90A, 90B for individually accommodating the two second connection elements 71. The two single-connection sections 90A, 90B are, in particular, coupled together with a base section 82. In other words, the two single-connection sections 90A, 90B are formed integrally or integrally by the base section 82.

[0112] Each connection-receiving section 90A, 90B is essentially, for example, in the form of a box extending along the second opposite direction Y2 from the base section 82. In other words, each connection-receiving section 90A, 90B is in the form of a ring with a bottom, which has a bottom wall 91. The bottom wall 91 is, in particular, formed by a circumferential wall in the second opposite direction Y2 in the connection-receiving section 90A, 90B.

[0113] An internal or interior space of each section 90A, 90B receiving a connection communicates in particular with the (in particular each) through-hole 82X (see Fig. 11) of basic section 82.

[0114] The second connecting element 71 is to be at least partially accommodated within the interior of each section 90A, 90B receiving a connection. Each section 90A, 90B receiving a connection includes an insertion hole 92 into which the first connecting element 21 of the first connector 20 is at least partially inserted.

[0115] Specifically, each insertion hole 92 is configured to pass through a circumferential wall 93 in the first opposite direction X2 of each connection-receiving section 90A, 90B. Each insertion hole 92 passes through the circumferential wall 93 along the first direction X1 parallel to the assembly direction D1. Each insertion hole 92 communicates with the interior of each connection-receiving section 90A, 90B. Each connection-receiving section 90A, 90B holds the second connection element 71, with the connecting section 72 of each second connection element 71 being exposed in the interior of each connection-receiving section 90A, 90B.

[0116] Furthermore, the two connection sections 90A and 90B are specifically designed to be essentially adjacent to each other along the third direction Z1. The two connection sections 90A and 90B are positioned far apart from each other in the third direction Z1. That is, a gap or free space is provided between the two connection sections 90A and 90B.

[0117] The single-termination section 90A has, in particular, a facing surface 94A which is substantially directed towards the single-termination section 90B. The facing surface 94A is a surface in the third opposite direction Z2 in the single-termination section 90A. The single-termination section 90B has a facing surface 94B which is substantially directed towards the single-termination section 90A.

[0118] As this is in Fig. As shown in Figure 6, the second connector housing 80 includes one or more second fitting section(s) 100, which is to be fitted or form-fitted convexly-concave to the first fitting sections 50 of the first connector 20.

[0119] Specifically, the second fitting sections 100 are to engage with the first fitting sections 50 in a direction that intersects or crosses the assembly direction D1. The second fitting sections 100 are provided in the inner housing 81.

[0120] As this is in Fig. As shown in Figure 12, one or more second fitting sections 100 are provided, for example, on the facing surface 94A of the section 90A receiving a connection and / or on the facing surface 94B of the section 90B receiving a connection. That is, the second connector housing 80 of this embodiment specifically includes two second fitting sections 100.

[0121] As this is in Fig. As shown in Figure 9, each second fitting section 100 includes one or more projections 101 (six in this embodiment) and one or more recesses 102 (seven in this embodiment). Specifically, in each second fitting section 100, the multiple (e.g., six) projections 101 and the multiple (e.g., seven) recesses or indentations 102 are arranged alternately, essentially side by side, in the second direction Y1. The multiple (six) projections 101 are to be fitted to the multiple (six) recesses 52. The multiple (seven) recesses 102 are to be fitted to the multiple (seven) projections 51.

[0122] When the second connector 70 is assembled with the first connector 20, the projections 51 of the first fitting section 50 and the projections 101 of the second fitting section 100 engage at least partially with each other in the second direction Y1.

[0123] When the second connector 70 is connected to the first connector 20, the side walls 43 of the two protective sections 40A, 40B and the coupling wall 47 are at least partially fitted into a free space or gap between the facing surfaces 94A and 94B of the two connection-receiving sections 90A, 90B. In this embodiment, the two second fitting sections 100 are convex-concave fitted to the two first fitting sections 50, which are provided on the two side walls 43, (in particular from both sides) in the third direction Z1 and / or the third opposite direction Z2.

[0124] Specifically, the second fitting section 100, which is provided on the facing surface 94A, is fitted convexly-concave to the first fitting section 50, which is provided on the side wall 43 of the protective section 40A, and / or the second fitting section 100, which is provided on the facing surface 94B, is fitted convexly-concave to the first fitting section 50, which is provided on the side wall 43 of the protective section 40B. In other words, in a state in which the first and second connectors 20, 70 are properly fitted together, the projection(s) 51 of the first fitting section 50 is (in particular completely) inserted into the recess(s) 102 of the second fitting section 100, and / or the second fitting section 100 is fitted convexly-concave to the first fitting section 50, which is provided on the side wall 43 of the protective section 40B.The projection(s) 101 of the second fitting section 100 (in particular completely) are inserted or fitted into the recess(s) 52 of the first fitting section 50, so that as a result the one or more first fitting section(s) 50 are convex-concave fitted to the one or more respective second fitting section(s) 100 of the second connector 70 or are form-fitted to it or interlock with it.

[0125] More specifically, the one or more projections 101 (third projection) provided on the facing surface 94A are to be fitted to the one or more recesses 52 (first recess) provided in the side wall 43 of the protective section 40A. Furthermore, the one or more recesses 102 (second recess) provided on the facing surface 94A are to be fitted to the projection(s) 51 (first projection) provided on the side wall 43 of the protective section 40A.

[0126] Similarly, the one or more projections 101 (fourth projection) provided on the facing surface 94B are to be fitted to the one or more recesses 52 provided in the side wall 43 of the protective section 40B. Furthermore, the one or more projections 51 (second projection) provided on the side wall 43 of the protective section 40B are to be fitted to the one or more recesses 102 provided in the facing surface 94B.

[0127] In this embodiment, the two first fitting sections 50 are enclosed, in particular in a sandwich-like manner, by the two second fitting sections 100 in the third direction Z1, so that, as a result, the first fitting sections 50 are convexly-concave fitted or form-fitted with the second fitting sections 100 of the second connector 70 or interlock with them as soon as the first and second connectors 20, 70 are properly aligned or connected to each other.

[0128] Each projection 101 in one of the two second fitting sections 100 projects in the direction of the projection 101 in the other second fitting section 100. For example, each projection 101 provided on the facing surface 94A projects from the bottom surface of each recess 102 provided in the facing surface 94A in the direction of the facing surface 94B. For example, each projection 101 provided on the facing surface 94B projects from the bottom surface of each recess 102 provided in the facing surface 94B in the direction of the facing surface 94A. For example, each projection 101 essentially extends along the third direction Z1 or the third opposite direction Z2 from the bottom surface of each depression 102.

[0129] As this is in Fig. As shown in Figure 12, each projection 101 projects substantially along the first direction Z1 from an end surface 93A in the first opposite direction X2 of the circumferential wall 93. An axial direction of each projection 101, in which a central axis of each projection 101 substantially extends, is parallel to the first direction X1.

[0130] The (in particular each) projection 101 has a projecting end surface 101A, one or more side surfaces 101B (in particular a pair thereof) and / or an end surface 101C. The (each) projecting end surface 101A is an end surface which is provided at a position furthest away from the bottom surface of the recess 102 in the third direction Z1 of the end surfaces of each projection 101.

[0131] The projecting end surface 101A in one of the two second fitting sections 100 is substantially oriented towards the projecting end surface 101A in the other second fitting section 100. The projecting end surface 101A widens particularly in the first direction X1 and widens in the second direction Y1. The (each) side surface 101B widens particularly in the first direction X1 and / or in the third direction Z1.

[0132] Each side surface 101B specifically represents or forms the inner side surface of the recess 102. The end surface 101C is a surface in the first opposite direction X2 of the projection 101.

[0133] Specifically, each recess 102 is designed to be recessed or set off from the projecting end surface 101A of each projection 101. Each recess 102 extends substantially along the first direction X1 from the end surface 93A of the circumferential wall 93. For example, the bottom surface of each recess 102 in one of the two second fitting sections 100 is substantially directed towards the bottom surface of each recess 102 in the other second fitting section 100. A tip portion of each recess 102, i.e., an end portion in the first opposite direction X2 of each recess 102, is substantially open, for example, in the first opposite direction X2 parallel to the assembly direction D1.

[0134] As this is in Fig. As shown in Figure 13, a tip portion of each projection 101, i.e., an end portion in the first opposite direction X2 of each projection 101, includes in particular at least one leading or guide section 103, which is in particular designed in a tapered shape. The (in particular, each) leading section 103 is provided on an end portion of the (each) projection 101 closest to the first connector 20 (see Figure 13). Fig. 6) Each leading section 103 is designed, for example, to become narrower towards the end surface 93A of the circumferential wall 93. Specifically, each leading section 103 has at least one inclined surface 104 provided on one end surface 101C, and / or one or more inclined surface(s) 105 provided on the respective side surfaces 101B.

[0135] Specifically, the inclined surface 104 is inclined to approach the bottom surface of the recess 102 in the direction of the end surface 93A of the circumferential wall 93. The inclined surface 104 is provided, in particular, over the entire end surface 101C. The inclined surface 104 is, in particular, inclined substantially relative to a plane orthogonal to the assembly direction D1. Furthermore, the inclined surface 104 is, in particular, inclined substantially relative to a plane parallel to the assembly direction D1.

[0136] In particular, the inclined surface 105 is provided on the side surface 101B on a tip portion of the projection 101. The inclined surface 105 is, in particular, substantially inclined to approach a central axis of the projection 101 in the direction of the end surface 101C of the projection 101. The inclined surface 105 is, in particular, substantially inclined relative to a plane orthogonal to the assembly direction D1.

[0137] The inclined surface 105 is inclined, in particular, substantially relative to a plane parallel to the assembly direction D1. The inclined surface 105 is specifically designed to widen an opening width or opening width along the second direction Y1 of the recess 102 in the apex of the recess 102. The inclined surface 105 is formed, for example, by applying an R-chamfer or C-chamfer to a corner portion between the end surface 101C and the side surface 101B. The inclined surface 105 of this embodiment is formed by applying a C-chamfer to the corner portion between the end surface 101C and the side surface 101B.

[0138] The bottom surface of each recess 102 has, in particular, an inclined surface 106, which is provided in the apex of the recess 102. The inclined surface 106 is, in particular, substantially inclined to be separated from the projecting end surface 101A in the direction of the end surface 93A of the circumferential wall 93. The inclined surface 106 is, in particular, substantially designed to widen an opening width along the third direction Z1 of the recess 102 in the apex of the recess 102. The inclined surface 106 is inclined relative to a plane orthogonal to the assembly direction D1. The inclined surface 106 is, in particular, substantially inclined relative to a plane parallel to the assembly direction D1.

[0139] The inclined surface 106 is formed, for example, by applying an R-chamfer or a C-chamfer to a corner portion between the end surface 93A of the circumferential wall 93 and the bottom surface of the recess 102. In this embodiment, the inclined surface 106 is formed by applying a C-chamfer to the corner portion between the end surface 93A of the circumferential wall 93 and the bottom surface of the recess 102. A portion of the inclined surface 106 is, for example, formed continuously and integrally or in one piece with the inclined surface 104.

[0140] The leading section 103, i.e. the inclined surface(s) 104, 105 and / or 106, has a function of leading the projection 51 (see Fig. 7) of the first fitting section 50 into the recess 102 when the second connector 70 is assembled with the first connector 20. (Outer casing configuration 11)

[0141] As this is in Fig. 10 and Fig. As shown in Figure 14, the outer housing 110 at least partially surrounds the outer circumference of the inner housing 81. In other words, the inner housing 81 is or will be at least partially contained within the outer housing 110.

[0142] Specifically, the outer casing 110 is essentially in the form of a ring with a base, which has a base wall 111. For example, the outer casing 110 is in the form of a ring with a base, which is open in the second direction Y1 and has an opening in the second opposite direction Y2, which is closed by the base wall 111.

[0143] The outer housing 110 includes an opening 112 for at least partially exposing the circumferential walls 93 of the connection-receiving sections 90A, 90B. The opening 112 is provided, in particular, in a circumferential wall 113 in the first opposite direction X2 of the outer housing 110. The opening 112 is provided, in particular, on an end portion in the second opposite direction Y2 of the circumferential wall 113, i.e., an end portion of the circumferential wall 113 on the side of the bottom wall 111. The opening 112 passes, in particular, through the circumferential wall 113 substantially along the first direction X1 parallel to the assembly direction D1. The opening 112 communicates, in particular, with an interior of the outer housing 110.

[0144] One or more engaging section(s) 120 (four in this embodiment) is / are provided on the outer circumferential surface of the outer housing 110. The one or more engaging section(s) 120 is / are provided, for example, on the outer surface of the circumferential wall 113 on an end part in the second direction Y1.

[0145] As this is in Fig. As shown in Figure 10, one or more (two) engaging section(s) 120 are provided on the outer surface of the circumferential wall 113 on the end part in the second direction Y1. The one or more (two) engaging section(s) 120 are, for example, spaced apart from each other in the third direction Z1. The (each) engaging section 120 is, for example, configured to project radially outwards from the outer surface of the circumferential wall 113 away from the outer housing 110. As shown in Figure 10, one or more (two) engaging section(s) 120 are provided on the outer surface of the circumferential wall 113 on the end part in the second direction Y1. The one or more (two) engaging section(s) 120 are, for example, provided spaced apart from each other in the third direction Z1. The (each) engaging section 120 is, for example, configured to project radially outwards from the outer surface of the circumferential wall 113 away from the outer housing 110. Fig. As shown in Figure 1, two interlocking sections 120 are provided in a similar manner on a circumferential wall in the first direction X1 of the outer housing 110. (Configuration of the second connector 70)

[0146] As this is in Fig. As shown in Figure 14, the second connector 70 includes, for example, an inner member 130 for supporting the inner housing 81. The second connector 70 includes, for example, one or more annular sealing member(s) 140 (two in this embodiment), which is to be fitted into the interior of the inner member 130, and / or at least one annular sealing member 150, which is to be fitted onto the inner member 130 from the outside. (Configuration of inner link 130)

[0147] The inner link 130 is to be mounted on an end part in the second direction Y1 of the outer housing 110. The inner link 130 is, for example, a component separate from the inner housing 81. Part of the inner link 130 is, in particular, to be accommodated inside the outer housing 110.

[0148] The inner link 130 supports, in particular, the inner housing 81 inside the outer housing 110. The inner link 130 supports the inner housing 81, for example, by pressing or pushing the inner housing 81 towards the inner surface of the bottom wall 111 inside the outer housing 110.

[0149] As this is in Fig. As shown in Figure 15, the inner member 130 comprises at least one body section 131, at least one projecting section 132 which projects substantially in the second opposite direction Y2 from an end surface of the body section 131 in the second opposite direction Y2, and / or one or more engaging section(s) 133 (four in this embodiment). The inner member 130 is, for example, a single component in which the body section 131, the projecting section 132, and the engaging sections 133 are formed integrally or in one piece. The inner member 130 is, for example, made of an insulating resin or plastic material.

[0150] Body section 131 is specifically designed in a ring shape. Body section 131 is specifically in the form of a rectangular or right-angled ring overall. Body section 131 includes, for example, one or more (e.g., two) through-holes 131X, through which one or more (e.g., two) wires 75 pass (see Fig. 10) is / are individually guided through. One or more (e.g., two) sealing element(s) 140 is / are individually fitted into the respective one or more (two) passage holes 131X. Each passage hole 131X passes through the body section 131 in the second direction Y1. The passage hole 131X is, for example, designed to have a rectangular top view when viewed from one direction of penetration.

[0151] Body section 131 includes at least one partition 134, which at least partially separates or subdivides the plurality of (two) passage holes 131X. The partition 134 is provided between the adjacent (two) passage holes 131X in the third direction Z1.

[0152] The partition 134 is provided, for example, in a central or middle part in the third direction Z1 of the body section 131. The partition 134 extends, for example, over the entire length in the second direction Y1 of the body section 131.

[0153] The body section 131 includes one or more limiting walls 135 (four in this embodiment), which are provided on the inner circumferential surface of each passage opening 131X. Each limiting wall 135 is configured to project radially inward from the inner circumferential surface of the passage opening 131X at an end face in the second opposite direction Y2. For example, each limiting wall 135 extends substantially from a central or intermediate part in the second direction Y1 of the body section 131 to an end face in the second opposite direction Y2 of the body section 131.

[0154] At least one groove section 136, in which the sealing element 150 is specifically mounted or arranged, is provided in the outer circumferential surface of the body section 131. The groove section 136 is specifically provided in the outer circumferential surface of the body section 131 on the end part in the second, opposite direction Y2. The groove section 136 is specifically designed to be recessed or set off radially inward from the outer circumferential surface of the body section 131. The groove section 136 is specifically continuous or continuous over the entire circumference in one circumferential direction of the body section 131.The groove section 136 extends essentially, for example, from the central or intermediate part in the second direction Y1 of the body section 131 to or in the direction of the end surface in the second opposite direction Y2 of the body section 131.

[0155] The projecting section 132 extends, for example, in the second opposite direction Y2 from an end surface in the second opposite direction Y2 of the partition wall 134. For example, the projecting section 132 extends in the first direction X1 and / or has a certain (predetermined or determinable) thickness in the third direction Z1.

[0156] As this is in Fig. As shown in Figure 14, the projecting section 132 at least partially contacts the partition 83 of the base section 82 when the inner member 130 is mounted on the outer housing 110. The tip surface of the projecting section 132, i.e., an end surface in the second opposite direction Y2 of the projecting section 132, in particular contacts an end surface in the second direction Y1 of the partition 83. The projecting section 132 supports the inner housing 81 inside the outer housing 110, for example by contacting the partition 83 and pressing the inner housing 81 towards the bottom wall 111.

[0157] One or more (e.g., four) engaging section(s) 133 are provided to correspond to the one or more (e.g., four) engaging section(s) 120 of the outer housing 110. Each engaging section 133 is configured, for example, to project in the second opposite direction Y2 from an end part in the second direction Y1 of the body section 131. Each engaging section 133 is positioned away from the outer circumferential surface of the body section 131 in the first direction X1. Each engaging section 133 is in the form of a projecting element, which has a base end part connected to the body section 131 as a fixed end and a tip part on one side opposite the base end part in the second direction Y1 as a free end. Each engaging section 133 is configuredThe section 133 is designed to be deflectable in the first direction X1 by being deformed or reshaped in a way that allows it to return to its original position. Each engaging section 133 includes an engaging hole 133X with which the engaging section 120 engages. The engaging hole 133X extends, for example, in the second direction Y1. The engaging sections 133 and 120 engage with each other, for example, by means of a snap-fit ​​mechanism. By bringing the engaging sections 133 and 120 into engagement with each other, the inner link 130 is fixed to the outer housing 110. (Configuration of sealing elements 140, 150)

[0158] The two sealing elements 140 are each designed to correspond to the two wires 75. The two sealing elements 140 are mounted or arranged on the outer circumferential surfaces of the two wires 75. Each sealing element 140 is fitted inside each passage hole 131X. Each sealing element 140 is in the form of a ring, having an outer circumferential surface along the inner circumferential surface of the passage hole 131X. Each sealing element 140 includes a passage hole 141 through which each wire 75 passes. The inner circumferential surface of the passage hole 141 is shaped substantially in accordance with the outer circumferential surface of the wire 75. Each sealing element 140 is specifically configured to be resiliently deformable. Each sealing element 140 is, or rather...is, for example, in direct contact with the outer circumferential surface of the wire 75 and the inner circumferential surface of the passage hole 131X. The sealing element 140 (each) seals, in particular, between the outer circumferential surface of the wire 75 and the inner circumferential surface of the inner element 130. It should be noted that an end surface in the second opposite direction Y2 of the sealing element 140 (each) is in contact with the confining walls 135, which are located in . Fig. As shown in Figure 15, the sealing element 140 is located inside the passage hole 131X. The contact of each sealing element 140 with the confining walls 135 limits the extent to which the sealing element 140 can be inserted into the passage hole 131X. In other words, the confining walls 135 act to position each sealing element 140 inside the passage hole 131X.

[0159] As this is in Fig.As shown in Figure 14, the sealing element 150 is to be mounted, in particular, on the outer circumferential surface of the inner element 130. The sealing element 150 is, for example, mounted or arranged on the bottom surface of the grooved section 136 of the body section 131. The sealing element 150 is, in particular, provided inside the outer housing 110. The sealing element 150 is, in particular, in the form of a ring that extends around the entire circumference of the inner element 130 in one circumferential direction.

[0160] The outer circumferential surface of the sealing element 150 is shaped, in particular, substantially in accordance with the inner circumferential surface of the outer housing 110. The inner circumferential surface of the sealing element 150 is shaped, in particular, substantially in accordance with the outer circumferential surface of the inner element 130.

[0161] The sealing element 150 is configured and designed to be resilient and deformable. For example, the sealing element 150 is to be in direct or close contact with the outer circumferential surface of the inner element 130 and the inner circumferential surface of the outer housing 110. The sealing element 150 seals, in particular, between the outer circumferential surface of the inner element 130 and the inner circumferential surface of the outer housing 110.

[0162] The sealing elements 140, 150 are, for example, made of rubber. For instance, nitrile rubber, silicone rubber, urethane rubber, acrylic rubber, butyl rubber, ethylene propylene rubber, and the like can be used as the material for the sealing elements 140, 150.

[0163] Next, the functions and effects of this embodiment will be described. (1) The first connector housing 30 includes, in particular, one or more first fitting sections 50, designed to be or become convexly-concave fitted onto one or more second fitting sections 100, which are provided in the matching or aligned second connector 70, and to engage with the second fitting section(s) 100 in the second direction Y1, which intersects the assembly direction D1 of the first and second connectors 20, 70. By bringing the first fitting section(s) 50 into engagement with the second fitting section(s) 100, movement of the first connector housing 30 in the second direction Y1 is restricted. In this way, even if a vibration or oscillation is applied to the first connector 20, the movement of the first connector housing 30 in the second direction Y1 is limited.By exerting a force on the first connector housing 30, which is assembled with the second connector 70, a relative movement of the first connector housing 30 relative to the second connector housing 70 is restricted in the second direction Y1. In this way, it is possible to restrict the relative movement of the first connecting element(s) 21, which is / are held in the first connector housing 30, relative to the second connecting element(s) 71, which is / are provided in the second connector 70. As a result, wear at contact points between the first connecting element(s) 21 and the second connecting element(s) 71 can be suitably suppressed. (2) The first fitting section 50 includes, in particular, the one or more projections 51, which extend substantially along the third direction Z1 from the inner surface of the side wall 43 and project towards the first connecting member 21. The first connecting member 21 has, in particular, the connecting surface 24A, which is oriented substantially towards the projections or extensions 51 in the third direction Z1. The shortest distance L1 between the projecting end surface(s) 51A of the projection(s) 51 and the connecting surface 24A of the first connecting member 21 in the third direction Z1 is set or is defined as the first distance. Here, the first distance is, in particular, a distance in the range of approximately 3 mm or more and approximately 15 mm or less.The first distance is preferably in the range of approximately 6 mm or more and approximately 12 mm or less, more preferably in the range of approximately 6 mm or more and approximately 9 mm or less. By setting the shortest distance L1 as the first distance, it is possible to prevent a worker's finger from entering the space between the tips of the projections 51 and the contact surface 24A of the first connecting member 21. This prevents the worker's finger from contacting the contact surface 24A of the first connecting member 21 through the space between the tips of the projection(s) 51 and the contact surface 24A of the first connecting member 21. In this way, wear at the contact point can be suppressed, while simultaneously preventing electric shock. (3) The first connector housing 30 includes, in particular, the side wall 44, which is provided on the side opposite the side wall 43, which is provided with the first fitting section 50, transversely across the first connecting member 21 in the third direction Z1. The shortest distance L2 between the inner surface (third surface) of the side wall 44 and the non-connecting surface 24B (second surface) of the first connecting member 21 in the third direction Z1 is, in particular, equal to or shorter than the shortest distance L1, i.e., equal to or shorter than the first distance. In this way, it is possible to prevent the worker's finger from entering the gap between the inner surface of the side wall 44 and the non-connecting surface 24B of the first connecting member 21.In this way, it can be suppressed that the worker's finger contacts the first connecting element 21 through the free space between the inner surface of the side wall 44 and the non-connecting surface 24B of the first connecting element 21. (4) The first fitting sections 50 are provided, in particular, on the side walls 43, which are located between the majority of first connecting members 21. In this way, the first fitting sections 50 can be located close to the majority of first connecting members 21. Therefore, relative movements of the first connecting members 21 located close to the first fitting sections 50 can be suitably suppressed. (5) The first and second fitting sections 50, 100 engage with each other, in particular in the second direction Y1, in which the second openings 42 of the protective section 40 are open. In the case of the inclusion of the second openings 42, which are open in the second direction Y1 and intersect the assembly direction D1, the first connector housing 30 moves slightly relative to the second connector 70 in the second direction Y1 when the second connector 70 is assembled with the first connector 20. In this respect, the first fitting section(s) 50 engage with the second fitting section(s) 100 in the second direction Y1 in the above configuration, thus appropriately suppressing any relative movement of the connector housing 30 relative to the second connector 70 in the second direction Y1. (6) The first fitting section 50 is provided, in particular, on the inner surface of the side wall 43, which forms the protective section 40 surrounding the outer circumference of the first connecting member 21. In this way, the first fitting section 50 can be located close to the first connecting member 21. Therefore, any relative movement of the first connecting member 21, which is located close to the first fitting section 50, can be suitably suppressed. (7) The protective section 40 includes, in particular, the two protective sections 40A, 40B for individually protecting the two first connecting elements 21. Furthermore, the first fitting sections 50 include the one or more projections 51 (first projection) provided on the protective section 40A, and the one or more projections 51 (second projection) provided on the protective section 40B. In other words, the first fitting sections 50 are provided, in particular, on both of the two protective sections 40A, 40B. Thus, the first fitting section 50 can be located near each of the two first connecting elements 21. Therefore, relative movements of the two first connecting elements 21 can be suitably suppressed. (8) The first fitting section 50 includes, in particular, the one projection or projections 51 and the one or more recesses 52, which are recessed by the projecting end surface(s) 51A of the projection(s) 51. The projection 51 has, in particular, the one or more inclined surface(s) 54, 55 (first inclined surface) for guiding the projection 101 of the second fitting section 100 of the second connector 70 into the recess 52 when the second connector 70 is assembled with the first connector 20. In this way, when the second connector 70 is assembled with the first connector 20, the first and second fitting sections 50, 100 can be easily fitted convex-concave. This allows the second connector 70 to be easily assembled with the first connector 20. (9) The recess 52 has, in particular, the inclined surface 56 (second inclined surface) for guiding the projection 101 of the first fitting section 100 of the second connector 70 into the recess 52 when the second connector 70 is assembled with the first connector 20. In this way, when the second connector 70 is assembled with the first connector 20, the first and second fitting sections 50, 100 can be easily fitted convex-concave. This allows the second connector 70 to be easily assembled with the first connector 20. (10) The first connector housing 30 includes, in particular, one or more reinforcing sections 33, which couple(s) the base section 31 and the base end section(s) of the side wall(s) 43, which are provided with the first fitting section(s) 50. In this way, compared to a configuration that does not include the reinforcing section(s) 33, pivoting or oscillating movements of the side walls 43 can be suppressed when oscillation or vibration is applied to the first connector 20. In this way, relative movement of the first connector housing 30 can be suppressed, and correspondingly, relative movements of the first connecting members 21 can be suppressed. (11) The second connector 70 includes, in particular, one or more second fitting sections 100, designed to fit convexly-concave with one or more first fitting sections 50, which are provided in the matching first connector 20, and to engage with one or more first fitting sections 50 in the second direction Y1, which intersects the assembly direction D1 of the first and second connectors 20, 70. The one or more second fitting sections 100 are provided, in particular, in the inner housing 81 for at least partially receiving the second connecting elements 71. By bringing the second fitting section(s) 100 into engagement with the first fitting section(s) 100, respectively,Movement of the inner housing 81 in the second direction Y1 is restricted. Thus, even if a vibration is applied to the second connector 70, which is assembled with the first connector 20, relative movement of the inner housing 81 with respect to the first connector 20 in the second direction Y1 can be suppressed. In this way, it is possible to suppress relative movements of the second connecting element(s) 71, which is / are held in the inner housing 81, with respect to the first connecting element(s) 21, which is / are provided in the first connector 20. As a result, wear of the contact points between the first connecting elements 21 and the second connecting elements 71 can be effectively suppressed. (12) The inner housing 81 includes, in particular, the base section 82 and the connection receiving section or connection receiving section 90, which extends from the base section 82. The second fitting sections 100 are provided, in particular, on the outer surface of the connection receiving section 90 for at least partially receiving the second connection members 71 inside, from, or out of the inner housing 81. In this way, the second fitting section(s) 100 can be located near the second connection member(s) 71. Therefore, relative movements of the second connection member(s) 71, which is / are located near the second fitting section(s) 100, can be suitably suppressed. (13) The connection receiving section 90 includes, in particular, one or more connection receiving section(s) 90A, 90B for individually receiving one or more (e.g., two) second connection element(s) 71. The connection receiving section 90A has, in particular, the facing surface 94A, which is directed towards the connection receiving section 90B in the third direction Z1, and the connection receiving section 90B has, in particular, the facing surface 94B, which is directed towards the facing surface 94A. The one or more second fitting section(s) 100 includes, in particular, the one projection or the several projections 101 (third projection), which is provided on the facing surface 94B.are, and the one or more projections 101 (fourth projection) which is / are provided on the facing surface 94B. In other words, the second fitting sections 100 are provided, in particular, on both of the two connection-receiving sections 90A, 90B. In this way, the second fitting section(s) 100 can be provided near the second connection element(s) 71, which is / are received in the respective connection-receiving section(s) 90A, 90B. Therefore, relative movements of the second connection element(s) 71, which is / are provided near the second fitting section(s) 100, can be suitably suppressed. (14) The one or more projections 101 (third projection) provided on the facing surface 94A and the one or more projections 101 (fourth projection) provided on the facing surface 94B are specifically designed to be oriented towards each other in the third direction Z1. Thus, when the second connector 70 is assembled with the first connector 20, the (e.g., two) first fitting sections 50 of the first connector 20 are sandwiched together on both sides in the third direction Z1 by the (e.g., two) second fitting sections 100. Therefore, the two second fitting sections 100 are specifically convex-concave fitted or form-fitted to the two first fitting sections 50 on both sides in the third direction Z1.In this way, movements of the first connector housing 30 and the inner housing 81 in the second direction Y1 and the third direction Z1 can be suitably suppressed. As a result, relative movements of the first connector housing 30 and the inner housing 81 can be more suitably suppressed, and relative movements of the first and second connecting elements 21, 71 can be more suitably suppressed. (15) The second fitting section 100, which is provided on the facing surface 94A, includes in particular the one projection or projections 101 (third projection) and the one or more recesses 102 (second recess), which are recessed in the direction towards the facing surface 94A from the projecting end surface(s) 101A of the projection(s) 101. Similarly, the second fitting section 100, which is provided on the facing surface 94B, includes in particular the one projection or projections 101 and the one or more recesses 102, which are recessed in the direction towards the facing surface 94B from the projecting end surface(s) 101A of the projection(s) 101.The projection 101 (in particular each projection) has, in particular, the inclined surfaces 104, 105 (third inclined surface) for guiding the projection 51 of the first fitting section 50 of the first connector 20 into the recess 102 when the second connector 70 is assembled with the first connector 20. Thus, when the second connector 70 is assembled with the first connector 20, the first and second fitting sections 50, 100 can be easily fitted convexly-concave or form-fitted. In this way, the second connector 70 can be easily assembled with the first connector 20. (16) The recess 102 has, in particular, at least one inclined surface 106 (fourth inclined surface) for guiding the projection 51 of the first fitting section 50 of the first connector 20 into the recess 102 when the second connector 70 is assembled with the first connector 20. In this way, when the second connector 70 is assembled with the first connector 20, the first and second fitting sections 50, 100 can be easily fitted convexly-concave or form-fitted. This allows the second connector 70 to be easily assembled with the first connector 20. (17) The second connector 70 includes, in particular, the inner link 130 for supporting the inner housing 81 inside the outer housing 110. In this way, compared to a configuration that does not include the inner link 130, vibration of the inner housing 81 inside the outer housing 110 can be suppressed when a vibration is applied to the second connector 70. Thus, relative movement of the inner housing 81 can be suppressed, and consequently, relative movements of the second connector 70 can be suppressed. (18) The connection-receiving sections 90A, 90B are formed integrally or in one piece by the base section 82. In this way, the number of components can be reduced compared to the case where the connection-receiving sections 90A, 90B are configured or constructed as separate components. Furthermore, the two connection-receiving sections 90A, 90B can be supported or carried by the contact of the inner member 130 with the base section 82. In this way, the structure of the inner member 130 can be simplified compared to the case where structures for supporting the connection-receiving sections 90A, 90B are provided individually.
