DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of a connector assembly 1 and a back shell 100 of the present invention will be described with reference to the drawings. In addition, the same parts are given the same reference numerals in each drawing.

[0017] Embodiment 1 First, the basic configuration of a connector connection body 1 and a back shell 100 in the first embodiment will be described with reference to Figs. 1 and 2. Fig. 1 is a partial cross-sectional view showing a cross section of the back shell 100 included in the connector connection body 1 according to the first embodiment, together with a conduit 300 and a conduit joint 400. Fig. 2 is an exploded view showing the respective parts of Fig. 1 in an exploded state. Note that the conduit 300 is a protective member that houses a cable, and is also called an electric conduit.

[0018] [composition] The back shell 100 has a connector 10 attached to one end and a conduit joint 400 attached to the other end, and is configured to cover a cable 200 connected to the connector 10. The connector 10 to which the cable 200 can be connected and the back shell 100 attached to the connector 10 and covering the cable 200 constitute a connector assembly 1. The conduit joint 400 is provided at an end of a conduit 300 that houses the cable 200. Note that only a portion of the conduit 300 near the conduit joint 400 is shown in the figure.

[0019] Connector 10 has a shell 11 on its front side that has contacts for making contact with a mating connector, and a connection portion 12 on its rear side to which a signal line included in cable 200 is connected. Connector 10 is a circular connector that has shell 11 with a circular cross section. An end of the connecting portion 12 is provided with ring-shaped teeth 13 that mesh with teeth 113 provided on the back shell 100. The outer circumferential surface of the connecting portion 12 is provided with a threaded portion 14 that screws into a threaded portion 114 provided on the back shell 100.

[0020] The conduit joint 400 mainly has a cylindrical first joint portion 410 that is connected to the backshell 100 and that houses the cable 200 , and a cylindrical second joint portion 420 that is connected to the conduit 300 . The first joint part 410 is provided with a cylindrical internal space for passing the cable 200 therethrough, a threaded part 408 used when connecting to the backshell 100, and a cable support part 440 for holding the cable 200. The second joint part 420 is provided with a cylindrical internal space for receiving the conduit 300, and a conduit fixing part 430 for fixing the conduit 300 with a claw-shaped protrusion.

[0021] The back shell 100 mainly has a first cylindrical portion 110 and a second cylindrical portion 120. The first cylindrical portion 110 and the second cylindrical portion 120 are configured to have at least a portion having a cylindrical shape in order to maintain a fixed connection state at any angle among any rotation angles. One end of the first cylindrical portion 110 is attached to the connector 10, and the other end is connected to one end of the second cylindrical portion 120. The first cylindrical portion 110 and the second cylindrical portion 120 are connected at an arbitrary rotation angle along the same axial direction. The first cylindrical portion 110 and the second cylindrical portion 120 are configured to receive the cable 200 housed in the conduit 300 via the conduit joint 400 and cover the periphery of the cable 200 from the conduit joint 400 to the connector 10.

[0022] The first cylindrical portion 110 is configured with one end 111a and the other end 111b. On the one end 111a side of the first cylindrical portion 110, there are provided ring-shaped teeth 113 that mesh with teeth 13 provided on the end of the connector 10, a threaded portion 114 that screws into a threaded portion 14 provided on the connector 10, and a fastener screw hole 116 used for attaching the connector 10. In the first cylindrical portion 110, the ring-shaped teeth 113 and the threaded portion 114 may be provided according to the configuration of the connector 10. The first tubular portion 110 is configured to maintain the attachment state with the connector 10 by the second fastening portion 132 via the fastening portion screw hole 116. Although a specific example using a fastening screw is illustrated as the second fastening portion 132, various locking mechanisms and latching mechanisms can be used according to the configuration of the connector 10.

[0023] The other end 111b of the first cylindrical portion 110 is configured to be connected to one end 121a of the second cylindrical portion 120. Here, a state in which the first cylindrical portion 110 has a small diameter and the second cylindrical portion 120 has a large diameter and overlaps with each other is illustrated, but the small diameter and the large diameter may be reversed, or the ends may be connected to each other with the same diameter. One of the first and second cylindrical portions 110 and 120 is provided with a screw hole 126 for a stopper that is used when connecting the first and second cylindrical portions 110 and 120 at an arbitrary rotation angle along the same axial direction. The first and second cylindrical portions 110 and 120 are configured to maintain a connected state fixed at any one of the arbitrary rotation angles by a first stopper 131 via the screw hole 126 for the stopper. Although a specific example using a set screw is illustrated as the first stopper 131, various lock mechanisms and latch mechanisms that are rotatable and can limit rotation can be used depending on the configuration of the first and second cylindrical portions 110 and 120.

[0024] The second cylindrical portion 120 is configured to have one end 121a and the other end 121b. The one end 121a of the second cylindrical portion 120 is configured to be connected to the other end 111b of the first cylindrical portion 110. In the example shown in Fig. 1 and Fig. 2, the other end 111b of the first cylindrical portion 110 is accommodated in a cylindrical space of the one end 121a of the second cylindrical portion 120, and the first cylindrical portion 110 and the second cylindrical portion 120 are configured to have an arbitrary rotation angle.

[0025] The other end 121b of the second cylindrical portion 120 is provided with an attachment surface 122 for attaching the conduit joint 400 and a threaded portion 128 that screws into a threaded portion 408 provided on the conduit joint 400. The attachment surface 122 is formed based on a surface d that is inclined at an angle θ with respect to a surface v perpendicular to the axial direction, based on an angle determined according to the angle between the back shell 100 and the conduit joint 400. The surface v corresponds to an end surface where the angle θ=0, that is, there is no inclination. The threaded portion 128 is provided on an inner cylindrical surface that is formed perpendicular to the attachment surface 122. The angle θ is greater than 0° and less than 180°. In reality, the angle θ is often about 30° to 90°.

[0026] [Connection Procedure] A specific example in which backshell 100 in the first embodiment is used to connect a plurality of devices with cable 200 housed in conduit 300 will be described below. The connector 10, the backshell 100, the cable 200, the conduit 300, and the conduit joint 400 are connected and adjusted according to the following steps (a) to (f). Among the steps (a) to (f), the steps (c) to (e) can be performed in any order.

[0027] (a) The cable 200 housed in the conduit 300 is pulled out, and the pulled out cable 200 is passed through the inside of the conduit joint 400 and the back shell 100. (b) The internal signal lines are taken out from the cable 200 and connected to the contacts provided in the connection portion 12 of the connector 10. (c) One end of the back shell 100 is attached to the connector 10 by screwing the threaded portion 14 provided on the connector 10 into the threaded portion 114 provided on the back shell 100. Furthermore, the attachment state of the connector 10 and the back shell 100 is maintained by the second fastening portion 132. (d) Using the claw-like protrusions of the conduit fixing portion 430, the end of the conduit 300 is fixed to the conduit joint 400. (e) The threaded portion 128 of the back shell 100 is screwed into the threaded portion 408 provided on the conduit joint 400, and the conduit joint 400 is attached to the mounting surface 122 of the back shell 100. (f) The conduit 300 and the conduit joint 400 are adjusted so as to face in a desired direction. Furthermore, the angle between the first tubular portion 110 and the second tubular portion 120 is fixed by the first stopper portion 131, and the connection state between the first tubular portion 110 and the second tubular portion 120 is maintained.

[0028] [Appearance Configuration] Here, the appearance of the backshell 100 in the first embodiment during use will be described with reference to Figs. 3 and 4. Fig. 3 is a perspective view showing a first state of the connector connection body 1, the conduit 300, and the conduit joint 400 according to the first embodiment. Fig. 4 is a perspective view showing a second state of the connector connection body 1, the conduit 300, and the conduit joint 400 according to the first embodiment. Note that Figs. 3 and 4 only show a portion of the cable 200 and the conduit 300 near the conduit joint 400.

[0029] 3 and 4, the direction from backshell 100 toward connector 10 (leftward on the paper) is the X-axis, the direction in which conduit coupling 400 would extend if it were assumed that there was no inclination at all in mounting surface 122 (rightward on the paper) is the -X-axis, the direction toward the front of the paper is the Y-axis, and the direction upward on the paper is the Z-axis.

[0030] [First state] The first state shown in Fig. 3 will be described. The connector connection body 1, the conduit 300, and the conduit joint 400 are integrated by the above-mentioned steps (a) to (e). Then, the conduit 300 and the conduit joint 400 are adjusted to face the desired direction by the above-mentioned step (f). Furthermore, the angle between the first tubular portion 110 and the second tubular portion 120 is fixed by the first stopper portion 131, and the connection state between the first tubular portion 110 and the second tubular portion 120 is maintained. As described above, the connector connection body 1, the conduit 300, and the conduit joint 400 are integrated by the above-mentioned steps (a) to (e) and (f). 3, the connector connection body 1 faces the X-axis, and the mounting surface 122 faces a direction inclined from the -X-axis toward the Z-axis by an angle θ. Then, the conduit joint 400 and the conduit 300 extend in a direction inclined from the -X-axis toward the Z-axis by an angle θ in accordance with the inclination of the mounting surface 122.

[0031] [Second state] The second state shown in Fig. 4 will be described. The connector connection body 1, the conduit 300, and the conduit joint 400 are integrated by the above-mentioned steps (a) to (e). Then, the conduit 300 and the conduit joint 400 are adjusted to face the desired direction by the above-mentioned step (f). Furthermore, the angle between the first tubular portion 110 and the second tubular portion 120 is fixed by the first stopper portion 131, and the connection state between the first tubular portion 110 and the second tubular portion 120 is maintained. As described above, the connector connection body 1, the conduit 300, and the conduit joint 400 are integrated by the above-mentioned steps (a) to (e) and (f). 4, the connector connection body 1 faces the X-axis, and the mounting surface 122 faces a direction inclined from the -X-axis toward the Y-axis by an angle θ. Then, the conduit joint 400 and the conduit 300 extend in a direction inclined from the -X-axis toward the Y-axis by an angle θ in accordance with the inclination of the mounting surface 122.

[0032] [Change from 1st state to 2nd state] A description will be given of a case where the first state in Fig. 3 is changed to the second state in Fig. 4. That is, a procedure will be described for changing the connector connection body 1, the conduit 300, and the conduit joint 400 in the first state shown in Fig. 3 to the second state shown in Fig. 4. It is assumed that the connector connection body 1, the conduit 300, and the conduit joint 400 are in the first state through the above-mentioned steps (a) to (f). The conduit 300 and the conduit joint 400 extend in a direction at an angle θ from the -X axis toward the Z axis (see FIG. 3). First, when changing from the first state to the second state, the first fastening portion 131 is loosened. Then, the second cylindrical portion 120 is rotated about the X-axis without moving the first cylindrical portion 110. By rotating the second cylindrical portion 120, the conduit 300 and the conduit joint 400, which extend in a direction at an angle θ from the -X axis toward the Z axis, are tilted in a direction at an angle θ from the -X axis toward the Y axis (see FIG. 4). Then, the angle between the first cylindrical portion 110 and the second cylindrical portion 120 is fixed by the first stopper portion 131, and the connected state between the first cylindrical portion 110 and the second cylindrical portion 120 is maintained. In this manner, the change from the first state to the second state is completed. Furthermore, when changing from the first state to the second state, it is only necessary to rotate the second tubular portion 120 relative to the first tubular portion 110 without making any changes to the attachment between the connector 10 and the first tubular portion 110, which provides good operability for changing and adjusting the state.

[0033] In addition to those shown in Figures 3 and 4, the first tubular portion 110 and the second tubular portion 120 can be connected at any rotation angle along the same axial direction to orient the conduit 300 and the conduit joint 400 in any direction. Also, depending on the installation environment, it is sufficient to provide the second tubular portion 120 with an installation surface 122 having an inclination determined according to the angle between the back shell 100 and the conduit joint 400, and there is no need to modify the first tubular portion 110. Therefore, even when changing the inclination of the installation surface 122, it is sufficient to modify only the second tubular portion 120 without modifying the first tubular portion 110, which reduces costs compared to manufacturing the entire back shell 100 from scratch.

[0034] [Effects obtained by the embodiment] The backshell 100 described in the above embodiment is a backshell 100 including a first tubular portion 110 and a second tubular portion 120, and covering a cable 200 connected to a connector 10.

Therefore, when connecting multiple devices with the cable 200 housed in the conduit 300, it is possible to reliably connect the connector 10 and the conduit joint 400 at any angle, and it is easy to change or adjust to any direction and angle.

[0038] In the backshell 100 according to this embodiment, one end side of the first tubular portion 110 is further provided with a second fastening portion for maintaining the attachment state with the connector 10. Therefore, when connecting a plurality of devices with the cable 200 housed in the conduit 300, it becomes possible to reliably connect the connector 10 and the conduit joint 400 at any angle while reliably attaching the connector 10 to the backshell 100.
