[0014] As Figure 1 shown, a connector assembly 500 according to an embodiment of the present disclosure can be mounted and fixed to a device 600 such as a motor. At one end (not shown) of the connector assembly 500 to which a cable is connected, power can be supplied from the cable to the device 600 such as a motor via the connector assembly 500. In this specification, the so-called "connector assembly" corresponds to a combination of two or more connectors and may also be referred to as a connector unit.

[0015] As Figures 2A to 2F shown, 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 connection structures with different connection forms described below.

[0016] In addition, this embodiment is premised on the cable being able to be led out in the horizontal direction (corresponding to the direction extending along the long side of the housing of the device 600 (refer to Figure 1 ) to which the connector assembly 500 is mounted).

[0017] (First Connector) As Figures 5A to 6 shown, the first connector 100 includes a first outer housing 140 capable of internally providing a first contact portion 180 connectable to a cable.

[0018] Specifically, the first outer housing 140 has an internal space 141 (refer to Figure 5F ) that is open on the side connected to the second connector in its main body portion 146. An inner housing 190 capable of accommodating the above-mentioned first contact portion 180 can be provided and installed in the internal space 141. In addition, the first connector 100 has a pair of locking members 160, 170 mounted on the outer surface 143 side of the outer housing 140 so as to face each other.

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

[0020] The cable is installed in such a way that it passes through the inside of these clamp rubber 130, cable clamp 120, and cap 110, and can be connected to the first contact portion 180 provided in the internal space 141 of the first outer housing 140.

[0021] As the pair of locking members 160, 170, for example, components having the following configuration can be used. Hereinafter, the locking member 160 will be mainly described, but the same configuration can also be adopted for the opposed locking member 170.

[0022] The locking member 160 has a leaf spring shape as a whole, and has a base portion 161, a folded-back portion (or inner bent portion) 162, and a press-fitting portion 163 that is press-fitted into the first outer housing 141. The base portion 161 extends along the fitting direction (vertical direction) of the two connectors, and has a locking hole 166 at the lower part for locking to the second connector 200.

[0023] In the base portion 161, a protrusion protruding outward from the first connector 100 in the plate thickness direction is provided above the locking hole 166. This protrusion is a component for transmitting the touch feeling of the locking member to the fingers when the operator pinches the locking member with the fingers from left and right, so that the operator can know the position of the locking member. The 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 locked to a locking portion 147 provided at a predetermined interval from the outer surface of the first outer housing 141. The folded-back portion 162 is a portion that is continuous with the upper part of the base portion 161 and advances in the direction opposite to the fitting direction (upward direction), bends inward, and then advances in the fitting direction (downward direction).

[0025] The press-fitting portion 163 is a portion that is continuous with the portion after the folded-back portion 162 is folded back, extends in a direction intersecting the fitting direction (the direction in which the cable can extend from the first connector 100), and is press-fitted into the first outer housing 141. With the involved configuration, the locking member 160 as a whole maintains the elasticity of a leaf spring, and at the same time, even if an accidental force is applied, the force will not be transmitted to the press-fitting portion 163.

[0026] A first bulging portion 167 that bulges inward of the first connector 100 in the plate thickness direction is formed in the pressing portion 163. The first bulging portion 167 can strongly interfere with the first outer housing 140 in a manner of being recessed into the first outer housing 140. Further, in the folded-back portion 162 of the locking member 160, a second bulging portion 168 that bulges inward of the first connector 100 in the plate thickness direction is formed in a portion that is folded back and advances in the fitting direction (downward direction). The second bulging portion 168 can also strongly interfere with the first outer housing in a manner of being recessed into the first outer housing 140, similarly to the first bulging portion 167.

[0027] (Second Connector) As Figures 3A to 4 shown, the second connector 200 includes a second connector base portion 230 having a second fitting portion 232. The second fitting portion 232 can internally provide a second contact portion 250 that can contact the first contact portion 180 described above, and can be fitted with the first outer housing 140. In the illustrated manner, the second contact portion 250 of the second connector 200 can be male, and the first contact portion 180 provided in the first connector 100 can be female. However, it is not limited thereto, and the second contact portion 250 of the second connector 200 can be female, and the first contact portion 180 provided in the first connector 100 can be male.

[0028] Specifically, the second fitting portion 232 of the second connector base portion 230 is configured such that one side is open for the second contact portion 250 to contact the first contact portion, and the other side is also open for the second contact portion 250 to contact a contact portion in a device 600 such as a motor (refer to Figure 1 ). That is, as Figure 4 shown, the second fitting portion 232 has a through internal space 233.

[0029] An internal housing 240 that can accommodate the second contact portion 250 can be provided and installed in the internal space 233. Further, the second fitting portion 232 has a fence portion 234 that extends in the fitting direction of the two connectors. When the first outer housing 140 and the second fitting portion 232 are fitted, the outer surface 235 of the fence portion 234 of the second fitting portion and the inner surface 144 of the first outer housing 140 (refer to Figure 5F ) can be configured to face each other.

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

[0031] With the configurations involved, a pair of locking members 160 and 170 mounted on the outer surface of the first outer housing 140 can be respectively latched to a pair of hook members 231 of the second connector base portion 230. In this way, based on the latching structure 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 outer 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] To improve the sealing performance when the first outer housing 140 and the second fitting portion 232 are fitted, the second connector 200 has a sealing member 220 that can be in contact with the fence portion 234 of the second fitting portion and also with the first outer housing 140. In addition, to improve the sealing performance when the second connector base portion 230 is connected to a device 600 such as a motor (refer to Figure 1 ), the second connector 200 also has a sealing member 260 in a groove provided on the main surface of the second connector base portion 230 on the side opposite to the formation portion 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 the respective corner portions of the rectangular second connector base portion 230. By inserting a connecting member 210 such as a threaded member into each through hole 237, the second connector base portion 230, that is, the second connector 200, can be finally connected to a device 600 such as a motor (refer to Figure 1 ).

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

[0035] According to the features involved, the first outer housing 140 and the second connector base portion 230 can be integrally connected not only by the mutual latching of the pair of locking members 160 and 170 and the pair of hook members 231, but also by the mutual connection using the connecting member 150. That is, in the present disclosure, the first outer housing 140 and the second connector base portion 230 can be integrally connected by two or more connection structures with different connection forms.

[0036] Thus, even if a minute gap is required for smooth connection between the two connectors 100 and 200, the two connectors 100 and 200 can be more appropriately connected to each other as compared with the case where the first outer housing 140 and the second connector base portion 230 are integrally connected by the engagement of a pair of locking members 160 and 170 and a pair of hook members 231 with each other.

[0037] As a specific solution for connecting the first outer housing 140 and the second connector base portion 230 to each other by the connecting member 150, the following solution can be adopted (refer to Figure 4 and Figure 6 etc.).

[0038] Specifically, the first outer 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. There is no particular limitation, but the number of through holes 145 may be one.

[0039] In addition, the second connector base portion 230 has an opening portion-containing space 238 (or 239) that extends in the fitting direction, is formed outside the second fitting portion 232, and can communicate with the through hole 145. On this basis, in the present disclosure, the connecting member 150 can be inserted in a state where the through hole 145 of the first outer housing 140 and the opening portion-containing space 238 (or 239) of the second connector base portion 230 communicate with each other. Thus, the first outer housing 140 and the second connector base portion 230 can be connected to each other by the connecting member 150. As the connecting member 150, for example, a threaded member can be used.

[0040] Regarding the opening portion-containing space of the second connector base portion 230, if the first outer housing 140 and the second connector base portion 230 can be connected to each other by the connecting member 150, it is not necessarily required to adopt a through hole method as compared with the through hole 145 of the first outer housing 140. In addition, from the viewpoint of production efficiency or the like, the opening portion-containing space of the second connector base portion 230 may also adopt a through hole method.

[0041] The second connector base portion 230 may have a pair of opening portion-containing spaces 238 and 239 that are disposed opposite to each other with the second fitting portion 232 interposed therebetween. On this basis, any one of one opening portion-containing space 238 and the other opening portion-containing space 239 and the through hole 145 of the first outer housing 140 can communicate with each other.

[0042] Although not particularly limited, from the viewpoint of improving the connection reliability of the portion where the above-described locking structure is not provided, it is preferable that the pair of hook members 231 disposed across the second fitting portion 232 in the second connector base portion 230 and the pair of open space portions 238, 239 are arranged in such a manner that the direction X in which the pair of hook members 231 are arranged intersects the direction Y in which the pair of open space portions 238, 239 are arranged (see Figure 3B ). When the shape of the second connector base portion 230 is rectangular in a top view, the hook members 231, the open space portion 238, the hook member 231, and the open space portion 239 may be provided in this order on each of the four continuous sides.

[0043] In this way, through the through-hole 145 of the first outer housing 140, it is possible to communicate with either one of the one open space portion 238 and the other open space portion 239, and two options for inserting the connecting member 150 can be provided. Thus, in a state where the second connector base portion 230 is connected to a device 600 such as a motor (see Figure 1 ), considering the desired cable lead-out direction and the like, the position of the through-hole 145 of the first outer housing 140 is overlapped with the position of either the one open space portion 238 or the other open space portion 239 so that the lead-out direction of the cable at the first connector 100 becomes a predetermined horizontal direction or a direction opposite to the predetermined horizontal direction.

[0044] That is, in the case of using the first connector 100 having the same structure, it is possible to select a mode in which the through-hole 145 of the first outer housing 140 communicates with either one of the one open space portion 238 and the other open space portion 239. Thereby, it is possible to provide two lead-out modes of the cable in the horizontal direction only by changing the arrangement of the first connector 100 having the same structure (see Figure 2A and Figure 7 ). Therefore, in the Figures 1 to 7 related embodiment, it is possible to improve the freedom of lead-out of the cable in the horizontal direction by a simple method.

[0045] In the mode of leading out the cable in the horizontal direction, the direction in which the cable (not shown) is led out from the first connector 100 and the insertion direction of the connecting member 150 may be different from each other. In other words, the direction in which the cable is led out from the first connector 100 and the fitting direction of the two connectors may be different from each other. For example, the direction in which the cable is led out and the insertion direction of the connecting member 150 (or the fitting direction of the two connectors) intersect, and preferably intersect perpendicularly.

[0046] In the above Figures 1 to 7In related embodiments, for example, the first contact portion, the second contact portion, the locking member, and the connecting member (such as a threaded member) may be made of a metal material. On the other hand, the constituent elements of the first connector 100 and the second connector 200 other than these may be made of a resin material. In addition, without being limited thereto, the outer housing of the connector may be made of a resin material and / or a metal material.

[0047] In addition, as an exemplary illustrated solution, it is based on the case where the covers 110 mounted on the first outer housing 140 are adjacent to each other and two are arranged side by side. However, without being limited thereto, the number of the covers 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. In the case where two or more electrical paths are required, it is sometimes used between a cable and a device such as a motor to ensure the following electrical paths: (1) an electrical path for supplying a power voltage for driving or braking the device to the device; and (2) an electrical path for transmitting a signal from a sensor (equivalent to an encoder) that detects rotational information of the device. Depending on the situation, it is sometimes further used to ensure the following electrical path: (3) an electrical path for transmitting a signal 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 the inner housings 240 installed in the inner space 233 of the second connector base portion 230, the arrangement pattern of the second contact portions used when ensuring two or more electrical paths, and the like. Similarly, it is preferable to appropriately adjust the number of the inner housings 190 installed in the inner space 141 (refer to Figure 5F ) of the first outer housing 140, the arrangement pattern of the first contact portions that can contact the second contact portions used when ensuring two or more electrical paths, and the like.

[0050] In addition, for a cable electrically connected to a device such as a motor, one cable may include two or more inner cables. Each inner cable may be composed of a wire such as a pure copper wire or a tinned copper wire, and an insulating inner cable film surrounding the outer periphery of the wire. On this basis, the front end of the inner cable and the contact portion accommodated in the inner housing of the connector may be connected to each other.

[0051] In one example, as illustrated in the present disclosure, a solution capable of connecting two or more cables as a whole can 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 sheath surrounding the first internal cable bundle, and an insulating covering member surrounding the cable sheath. In addition, the second cable includes a second internal cable bundle composed of second internal cables of a type different from the first internal cables, a conductive cable sheath surrounding the second internal cable bundle, and an insulating covering member surrounding the cable sheath. For example, the insulating covering member surrounding the cable sheath can be formed of polyvinyl chloride (PVC), polypropylene, fluoropolymer, polyethylene, and / or polymers similar thereto.

[0052] In another example, one composite cable having different types of internal cables inside can be used as a whole. Taking as an example the case where one composite cable has different types of first and second internal cables inside, the outer surface of the composite cable itself having these internal cables inside can be composed of a conductive cable sheath and an insulating covering member surrounding it. In addition, a plurality of internal cables of the same type are bundled into a bundle, and on the other hand, the different types of first internal cables and second internal cables are further separated by a conductive cable sheath and an insulating covering member surrounding it.

[0053] Hereinafter, using Figures 8A to 8F , another embodiment of the present disclosure will be described. In addition, in this embodiment, from the viewpoint of avoiding repeated description, the description will be centered on aspects different from the embodiment Figures 1 to 7 related to.

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

[0055] Figures 8A to 8F The embodiment related to Figures 1 to 7Compared with the related embodiments, the different aspect lies in: using a first connector with another structure configured in such a way that the direction of the lead-out cable becomes the vertical direction. In this case, as Figure 8B , Figure 8C and Figure 8E show, the direction in which the cable is led out from the first connector 100B and the insertion direction of the connecting member 150B can become substantially the same. In other words, the direction in which the cable is led out from the first connector 100B and the fitting direction of the two connectors can become substantially the same.

[0056] In addition, in the Figures 1 to 7 related embodiment, in order to lead out the cable 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 cover 110 mounted on the cylindrical portion 142 (refer to Figure 6 ) can be located above one of the two spaces with openings in the second connector base portion 230.

[0057] This situation can become significant when the above-mentioned cylindrical portion 142 or the cover 110 is arranged adjacent to and side by side in two. Due to the above structure, in addition to the two locking points using the locking structure, the number of connection points between the first outer housing 140 and the second connector base portion 230 using the connecting member (such as a threaded member) can become one.

[0058] On the other hand, in the Figures 8A to 8F related embodiment, since the cable can be led out in the vertical direction, the cylindrical portion of the first outer housing 140B or the cover 110B mounted on the cylindrical portion can be located above neither of the two spaces with openings in the second connector base portion 230.
