[0014] As shown in FIG. 1, a connector assembly 500 according to an embodiment of the present disclosure can be attached and fixed to a device 600 such as a motor. One end (not shown) of a cable is connected to the connector assembly 500, and power can be supplied from the cable to the device 600 such as a motor through the connector assembly 500. In this specification, the "connector assembly" corresponds to a combination of two or more connectors and can also be referred to as a connector unit.

[0015] As shown in FIGS. 2A to 2F, a connector assembly 500 according to an embodiment of the present disclosure includes a first connector 100 and a second connector 200. The first connector 100 can be configured to be connectable to one end of a cable. The first connector 100 and the second connector 200 can be integrally connected to each other by two different connection mechanisms having different connection forms described below.

[0016] Further, this embodiment is premised on the fact that the cable can be pulled out in the horizontal direction (corresponding to the direction along the longitudinal extension direction of the housing of a device 600 (see FIG. 1) such as a motor to which the connector assembly 500 is attached).

[0017] (First Connector) As shown in FIGS. 5A to 6, the first connector 100 includes a first outer housing 140 in which a first contact 180 connectable to a cable can be installed inside.

[0018] Specifically, the first outer housing 140 has an internal space 141 (see FIG. 5F) with an opening on the side connected to the second connector in its main body portion 146. An internal housing 190 capable of accommodating the first contact 180 is installed and attachable inside this internal space 141. Further, the first connector 100 has a pair of lock members 160, 170 attached to face each other on the outer surface 143 side of the outer housing 140.

[0019] The first connector 100 has a cylindrical portion 142 with an opening for a cable for inserting the cable in the first outer housing 140. A screw portion is formed on the outer periphery of this cylindrical portion 142. Further, in addition to the first outer housing 140, the first connector 100 includes a cylindrical clamp rubber 130 (functioning as a waterproof rubber) that can be inserted into the inner peripheral side of the cylindrical portion 142, a cable clamp 120, and a cap 110 having a screw portion on its inner periphery that can be connected to the screw portion on the outer periphery of the cylindrical portion 142.

[0020] The cable is attached so as to pass through these clamp levers 130, the cable clamp 120, and the inside of the cap 110, and can be connected to the first contact 180 installed in the internal space 141 of the first outer housing 140.

[0021] As the pair of locking members 160 and 170 described above, for example, those having the following configuration can be used. Hereinafter, the locking member 160 will be mainly described, but the locking member 170 arranged opposite thereto can also have a similar configuration.

[0022] The locking member 160 has a leaf spring shape as a whole, and includes a base portion 161, a folded-back portion (or inner curved portion) 162, and a press-fitting portion 163 press-fitted into the first outer housing 141. The base portion 161 extends in the fitting direction (vertical direction) of both connectors, and has a locking hole 166 for locking to the second connector 200 downward.

[0023] On this base portion 161, above the locking hole 166, a protruding portion protruding outward from the first connector 100 in the direction of the plate thickness is provided. This protruding portion is for transmitting the feel of the locking member to the finger when the operator pinches the locking member with a finger from the left and right, and informing the operator of the position of the locking member. This base portion 161 can be arranged on the outer wall surface provided at a predetermined interval from the outer surface of the first outer housing 141.

[0024] The folded-back portion 162 can be hooked on a hooking portion 147 provided at a predetermined interval from the outer surface of the first outer housing 141. The folded-back portion 162 is continuous with the upper part of the base portion 161, faces in the direction opposite to the fitting direction (upward), curves inward, and is a portion facing the fitting direction (downward).

[0025] The press-fitting portion 163 is continuous with the portion of the folded-back portion 162 after folding back, extends in a direction intersecting the fitting direction (the direction in which the cable can extend from the first connector 100), and is a portion press-fitted into the first outer housing 141. With such a configuration, while the locking member 160 maintains the spring property as a leaf spring as a whole, even if it receives an unintended force, the force is not transmitted to the press-fitting portion 163.

[0026] In the press-fitting portion 163, a first bulging portion 167 that bulges inward of the first connector 100 in the direction of the plate thickness is formed. This first bulging portion 167 can strongly interfere with the first outer housing 140 so as to bite into the first outer housing 140. Also, in the folded-back portion 162 of the locking member 160, at the portion that folds back and faces the fitting direction (downward), a second bulging portion 168 that bulges inward of the first connector 100 in the direction of the plate thickness is formed. This second bulging portion 168 can also strongly interfere with the first outer housing 140 so as to bite into the first outer housing 140, similar to the first bulging portion 167.

[0027] (Second connector) As shown in FIGS. 3A to 4, the second connector 200 includes a second connector base portion 230 that can internally install a second contact 250 capable of contacting the above-described first contact 180 and has a second fitting portion 232 capable of fitting with the first outer housing 140. In the illustrated form, the second contact 250 of the second connector 200 can be a male type, and the first contact 180 provided on the first connector 100 can be a female type. However, it is not limited to this, and the second contact 250 of the second connector 200 can be a female type, and the first contact 180 provided on the first connector 100 can be a male type.

[0028] Specifically, the second fitting portion 232 of the second connector base portion 230 has a configuration in which one side is open so that the second contact 250 can contact the first contact, and the other side is also open so that the second contact 50 can contact the contact within a device 600 (see FIG. 1) such as a motor. That is, as shown in FIG. 4, the second fitting portion 232 has a penetrated internal space 233.

[0029] An internal housing 240 capable of accommodating the second contact 250 is installed and attachable within this internal space 233. Further, the second fitting portion 232 has an enclosing portion 234 extending in the fitting direction of the two connectors. When the first external housing 140 and the second fitting portion 232 are fitted, the outer surface 235 of the enclosing portion 234 of the second fitting portion and the inner surface 144 (see FIG. 5F) of the first external housing 140 can be arranged to face each other.

[0030] The second connector base portion 230 has a pair of hook members 231 positioned to face each other outside the second fitting portion 232 described above. Each hook member 231 has, on its inner side, a protruding portion 236 that can be locked with the locking holes 166 and 176 of the respective locking members 160 and 170 in the first connector 100.

[0031] With such a configuration, a pair of locking members 160 and 170 attached to the outer surface of the first external housing 140 can be respectively locked to the pair of hook members 231 of the second connector base portion 230. As described above, based on the locking mechanism using the pair of locking members 160 and 170 and the pair of hook members 231 of the second connector base portion 230, the first external housing 140 can be fitted and connected to the second connector base portion 230. That is, the first connector 100 can be fitted and connected to the second connector 200.

[0032] In order to improve the sealing performance when the second connector 200 is fitted with the first external housing 140 and the second fitting portion 232, the second connector 200 has a seal member 220 that contacts the surrounding portion 234 of the second fitting portion and can also contact the first external housing 140. Further, in order to improve the sealing performance when the second connector base portion 230 of the second connector 200 is connected to a device 600 such as a motor (see FIG. 1), the second connector 200 also has a seal member 260 in a groove provided on the main surface of the second connector base portion 230 on the side opposite to the formation location of the second fitting portion 232.

[0033] In addition, the second connector base portion 230 has a plurality of through holes 237. When the shape of the second connector base portion 230 is rectangular in a top view, the through holes 237 can be arranged at each corner portion of the rectangular second connector base portion 230. A connecting member 210 such as a screw member is inserted into each through hole 237, and finally, the second connector base portion 230, that is, the second connector 200 can be interconnected with a device 600 such as a motor (see FIG. 1).

[0034] Here, the connector assembly 500 of the present disclosure is characterized in that not only a locking mechanism using a pair of lock members 160 and 170 and a pair of hook members 231 of the second connector base portion 230, but also the first external housing 140 and the second connector base portion 230 can be mutually connected by a connecting member 150 as follows.

[0035] According to such a feature, the first external housing 140 and the second connector base portion 230 can be integrally connected by the mutual connection by the connecting member 150 in addition to the mutual locking of the pair of lock members 160 and 170 and the pair of hook members 231. That is, in the present disclosure, the first external housing 140 and the second connector base portion 230 can be integrally connected by two or more connection mechanisms having different connection forms.

[0036] Thus, even if a minute clearance is required to smoothly connect between the two connectors 100 and 200, the first external housing 140 and the second connector base portion 230 can be more suitably interconnected with each other as compared with the case where they are integrally connected by the mutual locking of a pair of lock members 160 and 170 and a pair of hook members 231.

[0037] As a specific aspect of interconnecting the first external housing 140 and the second connector base portion 230 with each other by the connecting member 150, the following aspect can be adopted (see FIGS. 4 and 6, etc.).

[0038] Specifically, the first external housing 140 has a through hole 145 formed on the outer surface side of the main body portion 146 and extending in the fitting direction of the first connector 100 and the second connector 200. Although not particularly limited, the number of through holes 145 may be one.

[0039] Further, the second connector base portion 230 extends in the fitting direction, is formed outside the second fitting portion 232, and has a space 238 (or 239) with an opening that can communicate with the through hole 145. Then, in the present disclosure, the connecting member 150 can be inserted in a state where the through hole 145 of the first external housing 140 communicates with the space 238 (or 239) with an opening of the second connector base portion 230. Thereby, the first external housing 140 and the second connector base portion 230 can be interconnected with each other by the connecting member 150. As the connecting member 150, for example, a screw member can be used.

[0040] Regarding the space with an opening of the second connector base portion 230 above, if the first external housing 140 and the second connector base portion 230 can be interconnected with each other by the connecting member 150, it is not always necessary to adopt the form of a through hole as compared with the through hole 145 of the first external housing 140. From the viewpoint of production efficiency and the like, the space with an opening of the second connector base portion 230 may also adopt the form of a through hole.

[0041] The second connector base portion 230 may have a pair of spaces 238, 239 with openings that are disposed opposite to each other with the second fitting portion 232 therebetween. Then, either one of the space 238 with an opening and the other space 239 with an opening is in communication with the through hole 145 of the first outer housing 140.

[0042] Although not particularly limited, from the viewpoint of improving connection reliability in a portion where the above locking mechanism is not disposed, in the second connector base portion 230, the direction X in which a pair of hook members 231 disposed opposite to each other with the second fitting portion 232 therebetween is disposed, and the direction Y in which the above pair of spaces 238, 239 with openings is disposed preferably intersect with each other, and the above pair of spaces 238, 239 with openings is disposed (see FIG. 3B). When the shape of the second connector base portion 230 is rectangular in a top view, on each of the four continuous sides, the hook member 231, the space 238 with an opening, the hook member 231, and the space 239 with an opening may be provided in this order.

[0043] In this way, since the through hole 145 of the first outer housing 140 can communicate with either one of the space 238 with an opening and the other space 239 with an opening, two options for inserting the connection member 150 are provided. Thereby, in a state where the second connector base portion 230 is connected to a device 600 such as a motor (see FIG. 1), considering a desired cable drawing direction or the like, the position of the through hole 145 of the first outer housing 140 is overlapped with the position of either the space 238 with an opening or the other space 239 with an opening so that the cable drawing direction in the first connector 100 becomes a predetermined horizontal direction or a direction opposite to the predetermined horizontal direction.

[0044] That is, when using the first connector 100 with the same structure, it is possible to select a pattern that connects the through hole 145 of the first outer housing 140 to either one of the space 238 with an opening and the space 239 with an opening. As a result, by simply changing the arrangement of the first connector 100 with the same structure, it becomes possible to provide two cable extraction patterns in the horizontal direction (see FIGS. 2A and 7). Therefore, in the embodiments related to FIGS. 1 to 7, it is possible to easily increase the degree of freedom in cable extraction in the horizontal direction.

[0045] In the pattern of extracting the cable in the horizontal direction, the direction in which the cable (not shown) is pulled out from the first connector 100 and the insertion direction of the connection member 150 can be different from each other. In other words, the direction in which the cable is pulled out from the first connector 100 and the fitting direction of the two connectors can be different from each other. For example, the direction in which the cable is pulled out intersects, preferably perpendicularly intersects, the insertion direction of the connection member 150 (or the fitting direction of the two connectors).

[0046] In the embodiments related to FIGS. 1 to 7 above, for example, the first contact, the second contact, the lock member, and the connection member (such as a screw member) can be made of a metal material. On the other hand, the components of the first connector 100 and the second connector 200 other than these can be made of a resin material. Note that it is not limited to this, and the outer housing of the connector can be made of a resin material and / or a metal material.

[0047] Also, as an exemplary embodiment shown in the figures, it is based on the case where two caps 110 attached to the first outer housing 140 are arranged in parallel adjacent to each other. However, it is not limited to this, and the number of caps 110 may be one, or may be three or more.

[0048] As described above, the connector assembly of the present disclosure is used to ensure an electrical path between a cable and a device. When two or more electrical paths are required, between a cable and a device such as a motor, (1) an electrical path for supplying a power supply voltage for driving or braking the device to the device, and (2) a sensor (equivalent to an encoder) for detecting rotational information or the like of the device It may be used to secure an electrical path for signal transmission from. In some cases, further, (3) it may be used to further secure an electrical path for signal transmission to a component (equivalent to a brake) for stopping the operation of the device.

[0049] In this case, it is preferable to appropriately adjust the number of internal housings 240 attached in the internal space 233 of the second connector base portion 230, the arrangement pattern of the second contacts used when securing two or more electrical paths, and the like. Similarly, it is preferable to appropriately adjust the number of internal housings 190 attached in the internal space 141 (see FIG. 5F) of the first external housing 140, the arrangement pattern of the first contacts that can contact the second contacts used when securing two or more electrical paths, and the like.

[0050] Also, for a cable electrically connected to a device such as a motor, one cable may include two or more internal cables. Each internal cable may be composed of a conductive wire such as a pure copper wire or a tin-plated copper wire, and an insulating internal cable coating surrounding the outer periphery of the conductive wire. Then, the tip of this internal cable and the contact housed in the internal housing of the connector can be connected to each other.

[0051] In one example, as exemplarily illustrated in the present disclosure, an embodiment in which two or more cables can be connected as a whole may be adopted. In this case, for example, the first cable includes a first internal cable bundle composed of a plurality of first internal cables of the same type, a conductive cable shield surrounding the first internal cable bundle, and an insulating covering member surrounding the cable shield. Further, the second cable includes a second internal cable bundle composed of second internal cables different from the first internal cables, a conductive cable shield surrounding the second internal cable bundle, and an insulating covering member surrounding the cable shield. For example, the insulating covering member surrounding the cable shield may be formed from polyvinyl chloride (PVC), polypropylene, fluoropolymers, polyethylene, and / or polymers of the same type as them.

[0052] In another example, as a whole, a single composite cable having different types of internal cables therein may be used. Taking as an example the case where a single composite cable has different first and second internal cables therein, the outer surface of the composite cable itself having these internal cables therein may be composed of a conductive cable shield and an insulating covering member surrounding the same. Note that a plurality of internal cables of the same type are bundled together, while between the different first internal cable and the second internal cable, they are further separated by a conductive cable shield and an insulating covering member surrounding the same.

[0053] Hereinafter, with reference to FIGS. 8A to 8F, still another embodiment of the present disclosure will be described. In this embodiment, from the viewpoint of avoiding duplication of description, the description will focus on the differences compared with the embodiments related to FIGS. 1 to 7.

[0054] FIG. 8A is a perspective view schematically showing a connector assembly according to still another embodiment of the present disclosure. FIG. 8B is a top view schematically showing a connector assembly according to still another embodiment of the present disclosure. FIG. 8C is a front view schematically showing a connector assembly according to still another embodiment of the present disclosure. FIG. 8D is a rear view schematically showing a connector assembly according to still another embodiment of the present disclosure. FIG. 8E is a side view schematically showing a connector assembly according to still another embodiment of the present disclosure. FIG. 8F is a bottom view schematically showing a connector assembly according to still another embodiment of the present disclosure.

[0055] The embodiment related to FIGS. 8A to 8F is different in that a first connector having a different structure is used, in which the direction in which the cable is pulled out is vertical, as compared with the embodiment related to FIGS. 1 to 7. In this case, as shown in FIGS. 8B, 8C, and 8E, the direction in which the cable is pulled out from the first connector 100B and the insertion direction of the connection member 150B can be substantially the same. In other words, the direction in which the cable is pulled out from the first connector 100B and the fitting direction of the two connectors can be substantially the same.

[0056] Further, in the embodiment related to FIGS. 1 to 7, since the cable can be pulled out in the horizontal direction, the cylindrical portion 142 of the first outer housing 140 (the cylindrical portion with a cable opening for inserting the cable) or the cap 110 attached to the cylindrical portion 142 (see FIG. 6) can be located above one of the two open spaces of the second connector base portion 230.

[0057] This fact can become prominent when the above-mentioned cylindrical portion 142 or cap 110 are arranged adjacent to each other in two in parallel. Due to the above structure, in addition to the two locking points by the locking mechanism, the number of connection points between the first outer housing 140 and the second connector base portion 230 using a connection member (such as a screw member) can be one.

[0058] On the other hand, in the embodiment related to FIGS. 8A to 8F, since the cable can be drawn out in the vertical direction, the cylindrical portion of the first external housing 140B or the cap 110B attached to the cylindrical portion can be prevented from being located above either of the two open spaces of the second connector base portion 230.

[0059] Due to the above structure, by adjusting to avoid interference between the outer surface of the first external housing 140B and the connecting member 150B (such as a screw member), in addition to the two locking points by the locking mechanism, it is possible to make the number of connection points between the first external housing 140B and the second connector base portion 230 using the connecting member 150B two.

[0060] As described above, in the embodiment related to FIGS. 8A to 8F, since the number of connection points between the first external housing 140B and the second connector base portion 230 by the connecting member 150B is two, compared with the embodiment related to FIGS. 1 to 7, even if a minute clearance is required to smoothly connect between the two connectors 100B and 200, it is possible to more preferably interconnect the two connectors 100B and 200.

[0061] The connector assembly of the present disclosure is not limited to the above embodiment. Within the scope of the present disclosure, modifications may be made as appropriate.

[0062] The connector assembly of the present disclosure may adopt the following aspects. <1> A first connector connectable to one end of a cable, and a second connector engageable with the first connector. The first connector includes a first external housing in which a first contact connectable to the cable can be installed inside, and the second connector includes a second connector base portion in which a second contact capable of contacting the first contact can be installed inside and which has a second fitting portion engageable with the first external housing. One of the first connector and the second connector base portion has a pair of locking members, and the other has a pair of hook members that can be mutually locked with the pair of locking members, and the first external housing and the second connector base portion can be mutually connected by a connecting member.
