It may be constituted by the body.

  FIG. 6 is a front view of the cable unit 10 as viewed from the plugs 21 and 31 side. In addition, since the adhesive agents 51 and 52 described with reference to FIG. 5 are thinner than the elastic bodies 50A to 50D, they are not illustrated in FIG. The attachment 40 has a first fitting hole 41 consisting of a first upper recess 40Aa of the upper case 40A and a first lower recess 40Ba of the lower case 40B, and a second upper recess 40Ab of the upper case 40A and a second of the lower case 40B.

The adhesive (52) of the outer surface 50b of the first lower elastic body 50C is fixed to the lower inner wall surface 41b of the first fitting hole 41. The size of the gaps X11 and X12 is, for example, 0.5 mm. Although the thickness of the first upper elastic body 50A and the first lower elastic body 50C before compression is, for example, 0.8 mm, in the state shown in FIG. 6, the thickness is compressed to the same thickness as the size of the gaps X11 and X12.

The sizes of the gaps X13 and X14 are set in consideration of dimensional tolerances of the first connection cable 20 and the attachment 40. Specifically, even if the maximum error occurs in the dimensions of the first connection cable 20 and the attachment 40, for example, the plug body 22 can be translated and rotated in the first fitting hole 41 as described later. The size is set to about 0.2 to 0.3 mm. Of course, the size of the gaps X13 and X14 may be larger than this.

  FIG. 7 is a horizontal cross-sectional view of the cable unit 10 and the electronic device 100, and is a view schematically showing the cable unit 10 and the electronic device 100 in a connected state. The plug 21 of the first connection cable 20 is inserted into the first connector 113 disposed in the first outlet 111. The plug 31 of the second connection cable 30 is inserted into the second connector 114 disposed in the second outlet 112.

  Here, the arrangement intervals of the plurality of connectors of the electronic device may not be as designed, due to dimensional tolerances and the like of the constituent members of the electronic device. Even in the prior art, there is an attachment for integrally holding a plurality of connection cables, but in the case of the conventional attachment, since the structure for strongly restraining the plurality of connection cables is used, the arrangement spacing of the connectors is as designed. If it is not the interval, the resistance at the time of cable insertion and removal increases, and there is a possibility that the pluggability is deteriorated, a heavy load is applied to the cable, and furthermore, the cable insertion and removal itself can not be performed.

  In the present embodiment, the above problem is solved by the structure described with reference to FIG. Hereinafter, the operation and effects of the cable unit 10 of the present embodiment will be described.

  FIG. 8 is a view for explaining the operation and effects of the cable unit 10 of the present embodiment. FIG. 8 shows the first connection cable 20 as a representative of the plurality of connection cables. Although the second connection cable 30 is not particularly described, the same operation and effect as the first connection cable 20 can be obtained.

  FIG. 8A is a view showing the cable unit 10 in an initial state in which the cable unit 10 is not connected to the electronic device 100. FIG. The left and right walls of the first fitting hole 41 of the attachment 40 are omitted. As described above, the upper outer wall surface 22a and the lower outer wall surface 22b of the plug body 22 of the first connection cable 20 are the first upper surfaces of the upper inner wall surface 41a and the lower inner wall surface 41b of the first fitting hole 41 of the attachment 40. It is fixed via the elastic body 50A and the first lower elastic body 50C. In FIG. 8, the first upper elastic body 50A and the first lower elastic body 50C are indicated by springs. In the state where the cable unit 10 is not connected to the electronic device 100, the plug body 22 of the first connection cable 20 is an elastic member of the first upper elastic body 50A and the first lower elastic body 50C in the first fitting hole 41. The force is held in a balanced neutral position.

  FIG. 8B is a diagram showing the cable unit 10 connected to the electronic device 100. FIG. 8B shows an example in which the first connector 113 of the electronic device 100 is inclined and displaced within the range of tolerance. Here, in order to insert the plug 21 of the first connection cable 20 into the first connector 113, the plug body 22 of the first connection cable 20 is guided by the inner wall of the first connector 113 into the first connector 113. In the present embodiment, the plug body 22 is supported in the first fitting hole 41 through the elastically deformable first upper elastic body 50A and the first lower elastic body 50C. Therefore, translational movement and rotational movement of the plug body 22 become possible. In addition, even when there is a positional deviation due to a tolerance in the arrangement position or the like of the first connector 113, the plug 21 of the first connection cable 20 can be inserted into the first connector 113. Further, the plug body 22 performs translational motion and rotational motion, thereby alleviating an increase in resistance at the time of cable insertion and removal, and smooth cable insertion and removal becomes possible. Further, it is possible to suppress that a large load is applied to the first connection cable 20 and the first connector 113 at the time of cable insertion and removal, and that the cable insertion and removal itself can not be performed.

  When the cable unit 10 is pulled out of the electronic device 100, the first upper elastic body 50A and the first lower elastic body 50C are restored to the initial shape of FIG. The first fitting hole 41 is returned to the initial position of FIG.

  Here, assuming that no adhesive is present on the outer surfaces 50a and 50b of the first upper elastic body 50A and the first lower elastic body 50C, the first upper elastic body 50A and the first lower elastic body 50C are removed at the time of cable insertion and removal. The attachment 40 may slip relative to the upper inner wall surface 41a and the lower inner wall surface 41b of the attachment 40 or the upper outer wall surface 22a and the lower outer wall surface 22b of the plug body 22 to cause positional deviation. In this case, the plug body 22 may not return to the initial position in the first fitting hole 41 of the attachment 40 even if the elastic bodies 50A and 50C are restored to the initial shape after the cable is pulled out. If the plug body 22 does not return to the initial position and a large positional deviation occurs, there is a possibility that the cable unit can not be connected to the electronic device 100 next. However, in the cable unit 10 according to the present embodiment, the presence of the adhesive on the outer surfaces 50a and 50b of the first upper elastic body 50A and the first lower elastic body 50C suppresses the positional deviation as described above. Ru.

  In addition, when the electronic device is a wearable electronic device, an irregular force accompanying the behavior of the user is repeatedly applied to the connection portion between the connector and the plug of the connection cable, but the connection cable is integrally held by the attachment. If this is not the case, the irregular force mentioned above can cause the connecting cable to tip off gradually. However, in the present embodiment, the irregular force as described above is applied by the two connecting cables 20 and 30 being integrally held and restrained by the attachment 40 via the elastic bodies 50A to 50D. Even in this case, the elasticity of the elastic bodies 50A to 50D causes the plugs 21 and 31 of the connection cables 20 and 30 to be in close contact with the connectors 113 and 114, so that detachment due to inclination or the like does not easily occur. Therefore, the convenience of the user in the case where the electronic device 100 is a wearable electronic device is improved.
