[0022] The following describes the method used for implementation.

[0023] [Description of embodiments of the present invention]

[0024] [1] One aspect of the present invention relates to a multi-core cable with a connector, comprising: a multi-core cable; and a connector having an axial direction along the length of the multi-core cable and connected to one end of the multi-core cable, the connector having: a first outer portion having a cylindrical peripheral wall portion having an opening at one end in the axial direction; and

[0025] The second outer part, connected to the first end, has: a first wall portion having a first through hole for inserting the multi-core cable; a first fixing portion connected to the first wall portion and inserted into the first wall portion; and a second fixing portion connected to the first wall portion, opposite to the first fixing portion, and inserted into the first wall portion. The connector has: a first snap-fit ​​mechanism for snapping the first fixing portion and the peripheral wall portion together; and a second snap-fit ​​mechanism for snapping the second fixing portion and the peripheral wall portion together. When viewed in a cross-section perpendicular to the axial direction, the multi-core cable is positioned between the first fixing portion and the second fixing portion. The first fixing portion supports the multi-core cable at two points, and the second fixing portion supports the multi-core cable at two points.

[0026] The connector has a first outer portion and a second outer portion. The second outer portion has a first wall portion with a first through hole for inserting a multi-core cable. Therefore, it can be configured such that flexibility is ensured by the second outer portion and strength is ensured by the first outer portion. Furthermore, the peripheral wall portion of the first outer portion and the first fixing portion of the second outer portion are engaged with each other by a first snap-fit ​​mechanism, and the peripheral wall portion of the first outer portion and the second fixing portion of the second outer portion are engaged with each other by a second snap-fit ​​mechanism, thus firmly connecting the first and second outer portions. Therefore, even if stress is applied to the multi-core cable in the direction of pull-out from the connector, separation between the first and second outer portions can be suppressed. Moreover, the first fixing portion supports the multi-core cable at two points, and the second fixing portion supports the multi-core cable at two points, thus suppressing displacement of the multi-core cable within the connector. Therefore, even when bending stress is applied to multi-core cables, it can suppress wire breakage and other issues within the connector.

[0027] [2] In [1], the first snap-fit ​​mechanism may have: a first protrusion disposed on the peripheral wall portion; and a first recess disposed on the first fixing portion for the first protrusion to be inserted. In this case, the first protrusion of the peripheral wall portion is inserted into the first recess of the first fixing portion, and the peripheral wall portion and the first fixing portion are securely joined.

[0028] [3] In [1], the first snap-fit ​​mechanism may have: a first recess disposed on the peripheral wall portion; and a first protrusion disposed on the first fixing portion and embedded in the first recess. In this case, the first protrusion of the first fixing portion is embedded in the first recess of the peripheral wall portion, and the peripheral wall portion and the first fixing portion are firmly joined.

[0029] [4] In [1] to [3], the second snap-fit ​​mechanism may have: a second protrusion disposed on the peripheral wall portion; and a second recess disposed on the second fixing portion for the second protrusion to be inserted. In this case, the second protrusion of the peripheral wall portion is inserted into the second recess of the second fixing portion, and the peripheral wall portion and the second fixing portion are firmly joined.

[0030] [5] In [1] to [3], the second snap-fit ​​mechanism may have: a second recess disposed on the peripheral wall portion; and a second protrusion disposed on the second fixing portion and embedded in the second recess. In this case, the second protrusion of the second fixing portion is embedded in the second recess of the peripheral wall portion, and the peripheral wall portion and the second fixing portion are firmly joined.

[0031] [6] In [1] to [5], when viewed in a cross-section perpendicular to the said axis, the first fixing part and the second fixing part may have a U-shaped shape. In this case, the first fixing part can easily support the multi-core cable at two points, and the second fixing part can easily support the multi-core cable at two points.

[0032] [7] In [1] to [6], the opening may be blocked by the first wall portion. In this case, it is possible to prevent foreign objects or the like from entering the connector from the outside.

[0033] [8] In [1] to [7], the connector may have a substrate disposed within the first outer casing and connected to one end of the multi-core cable. In this case, signals transmitted via the multi-core cable can be routed on the substrate.

[0034] [9] In [1] to [8], the first outer part may have a second wall portion connected to the other end of the peripheral wall portion, and have a second through hole, and the connector has an insertion terminal that is inserted into the second through hole. In this case, the connector can be inserted into an external device, etc., via the insertion terminal.

[0035]

[10] In [1] to [9], the first elastic modulus of the first material of the first outer part may be higher than the second elastic modulus of the second material of the second outer part. In this case, excellent strength can be obtained through the first outer part, and excellent flexibility can be obtained through the second outer part.

[0036]

[11] Another aspect of the invention relates to a multi-core cable with a connector comprising: a multi-core cable; and a connector having an axial direction along the length of the multi-core cable and connected to one end of the multi-core cable, the connector comprising: a protective cover having a cylindrical peripheral wall portion and a second wall portion, the cylindrical peripheral wall portion having an opening at one end in the axial direction, the second wall portion being connected to the other end of the peripheral wall portion and having a second through hole; a strain relief portion connected to the one end; and an insertion terminal inserted into the second through hole, wherein the first elastic modulus of a first material of the protective cover is higher than the second elastic modulus of a second material of the strain relief portion, the strain relief portion having: a first wall portion having a first through hole for insertion of the multi-core cable. A through hole is provided to block the opening; a first fixing part is connected to the first wall portion and inserted into the first wall portion; and a second fixing part is connected to the first wall portion, opposite to the first fixing part, and inserted into the first wall portion. The peripheral wall portion has a first protrusion and a second protrusion. The first fixing part has a first recess for the first protrusion to be inserted into, and the second fixing part has a second recess for the second protrusion to be inserted into. When viewed in a cross-section perpendicular to the axial direction, the multi-core cable is disposed between the first fixing part and the second fixing part. The first fixing part and the second fixing part have a U-shaped form. The first fixing part supports the multi-core cable at two points, and the second fixing part supports the multi-core cable at two points.

[0037] In this configuration, flexibility is ensured by the strain relief section, and strength is ensured by the protective cover. Furthermore, the protective cover and the strain relief section can be securely joined. Therefore, even if stress is applied to the multi-core cable in the direction of pull-out from the connector, separation between the protective cover and the strain relief section can be suppressed. Moreover, positional displacement of the multi-core cable within the connector can be suppressed. Therefore, even if bending stress is applied to the multi-core cable, breakage of the multi-core cable within the connector can be suppressed. Additionally, the entry of foreign objects from the outside into the connector can be prevented, and the connector can be inserted into external devices via the insertion terminals.

Furthermore, in this specification and accompanying drawings, structural elements that have substantially the same functional structure are labeled with the same reference numerals, and sometimes repeated descriptions are omitted.

[0046] [Structure of the protective cover]

[0047] Next, the structure of the protective cover 100 will be described. The protective cover 100 of the second connector 4 has the same structure as the protective cover 100 of the first connector 3, except for the direction based on the multi-core cable 2. Therefore, the structure of the protective cover 100 of the first connector 3 will be described in detail here, and the description related to the structure of the protective cover 100 of the second connector 4 will be omitted. Figure 3 This is a perspective view of the protective cover 100. Figure 4 This is a side view of the protective cover 100. Figure 5 and Figure 6 This is a cross-sectional view of the protective cover 100. Figure 4 This is a side view obtained from a side view taken from the rear (B). Figure 5 It is along Figure 3 and Figure 4 A cross-sectional view of the VV line. Figure 6 It is along Figure 3 and Figure 4A sectional view along line VI-VI.

[0048] like Figures 4-6 As shown, the protective cover 100 has a cylindrical peripheral wall portion 110, which has an opening 110X at its rear B-side end in the FB direction. The protective cover 100 also has a front wall portion 120, which is connected to the other end of the peripheral wall portion 110. The front wall portion 120 has a through hole 120X for insertion of the connector plug 6. The FB direction is an axial example. The front wall portion 120 is an example of a second wall portion. The through hole 120X is an example of a second through hole. The connector plug 6 is an example of an insertion terminal.

[0049] The peripheral wall portion 110 has a first sidewall 111 perpendicular to the RL direction, a second sidewall 112 perpendicular to the RL direction, a third sidewall 113 perpendicular to the UD direction, and a fourth sidewall 114 perpendicular to the UD direction. The second sidewall 112 is located to the left (L side) of the first sidewall 111, and the fourth sidewall 114 is located below the third sidewall 113 (D side). The first sidewall 111 is connected to the third sidewall 113 and the fourth sidewall 114. The second sidewall 112 is connected to the third sidewall 113 and the fourth sidewall 114.

[0050] A first protrusion 131 is provided on the inner wall surface 111A of the first sidewall 111. The first protrusion 131 has a wedge shape, and the wedge shape has an inclined surface 131A that is inclined relative to the inner wall surface 111A. The inclined surface 131A is inclined in such a way that it gets closer to the inner wall surface 111A the further back B is.

[0051] A second protrusion 132 is provided on the inner wall surface 112A of the second sidewall 112. The second protrusion 132 has a wedge shape, and the wedge shape has an inclined surface 132A that is inclined relative to the inner wall surface 112A. The inclined surface 132A is inclined in such a way that it gets closer to the inner wall surface 112A the further back B is.

[0052] The first protrusion 131 and the second protrusion 132 are provided, for example, near the end of the peripheral wall portion 110 on the rear B side.

[0053] The through hole 120X can have a rounded rectangular shape when viewed from the front F. That is, for example, the planar shape of the through hole 120X when viewed from the front F can include two parallel line segments and two outwardly protruding semicircles connecting these two line segments.

[0054] [Structure of the strain relief section]

[0055] Next, the structure of the strain relief section 200 will be described. The strain relief section 200 of the second connector 4 has the same structure as the strain relief section 200 of the first connector 3, except for the direction based on the multi-core cable 2. Therefore, the structure of the strain relief section 200 of the first connector 3 will be described in detail here, and the description related to the structure of the strain relief section 200 of the second connector 4 will be omitted. Figure 7 This is a perspective view showing the strain relief section 200. Figure 8 This is a side view showing the strain relief section 200. Figure 9 This is a cross-sectional view showing the strain relief section 200.

[0056] Figure 8 This is a side view obtained by observing from the left (L). Figure 9 It is along Figure 7 and Figure 8 A cross-sectional view of the IX-IX line.

[0057] like Figures 7-9 As shown, the strain relief section 200 has a rear wall portion 250, which has a through hole 250X for inserting a multi-core cable 2. The strain relief section 200 also has a first fixing portion 210 connected to the rear wall portion 250 and a second fixing portion 220 connected to the rear wall portion 250. The second fixing portion 220 is located to the left (L) of the first fixing portion 210, opposite to the first fixing portion 210. The first fixing portion 210 and the second fixing portion 220 are inserted into the peripheral wall portion 110 of the protective cover 100. The rear wall portion 250 is an example of the first wall portion. The through hole 250X is an example of the first through hole.

[0058] When viewed in a cross-section perpendicular to the FB direction, the first fixing part 210 has a U-shaped shape. For example, the first fixing part 210 includes: a horizontal plate part 211 extending in the FB direction with its normal pointing towards the RL direction; an upper plate part 212 connected to the upper U-side end of the horizontal plate part 211 with its normal pointing towards the UD direction; and a lower plate part 213 connected to the lower D-side end of the horizontal plate part 211 with its normal pointing towards the UD direction. The upper plate part 212 and the lower plate part 213 extend to the left (L-side) from the horizontal plate part 211. A first recess 231 is provided on the right (R-side) side surface 211A of the horizontal plate part 211. The first recess 231 has an inclined surface 231A that is inclined relative to the side surface 211A. The inclined surface 231A is inclined such that it gets closer to the side surface 211A the further back (B-side). The first protrusion 131 is embedded into the first recess 231, and the inclined surface 131A is in contact with the inclined surface 231A.

[0059] When viewed in a cross-section perpendicular to the FB direction, the second fixing part 220 has a U-shaped shape. For example, the second fixing part 220 includes: a horizontal plate part 221 extending in the FB direction with its normal pointing towards the RL direction; an upper plate part 222 connected to the upper U-side end of the horizontal plate part 221 with its normal pointing towards the UD direction; and a lower plate part 223 connected to the lower D-side end of the horizontal plate part 221 with its normal pointing towards the UD direction. The upper plate part 222 and the lower plate part 223 extend to the right R side from the horizontal plate part 221. A second recess 232 is provided on the left L-side side surface 221A of the horizontal plate part 221. The second recess 232 has an inclined surface 232A that is inclined relative to the side surface 221A. The inclined surface 232A is inclined such that it gets closer to the side surface 221A the further back B is. The second protrusion 132 is embedded into the second recess 232, and the inclined surface 132A contacts the inclined surface 232A.

[0060] For example, the front end 212A on the left L side of the upper plate 212 and the front end 222A on the left L side of the upper plate 222 are opposite to each other, and the front end 213A on the left L side of the lower plate 213 and the front end 222A on the right R side of the lower plate 223 are opposite to each other.

[0061] [Connector Structure]

[0062] Next, the structure of the connector will be described. The second connector 4 has the same structure as the first connector 3, except for the direction relative to the multi-core cable 2. Therefore, the structure of the first connector 3 will be described in detail here, while descriptions related to the structure of the second connector 4 will be omitted. Figure 10 This is a perspective view of connector 3. Figure 11 and Figure 12 This is a cross-sectional view showing the first connector 3. Figure 11 It is along Figure 10 A cross-sectional view of the XI-XI line. Figure 12 It is along Figure 10 A sectional view of line XII-XII in the diagram.

[0063] like Figures 10-12 As shown, the first protrusion 131 of the first sidewall 111 is inserted into the first recess 231 of the first fixing part 210, and the first fixing part 210 and the peripheral wall part 110 are engaged with each other. The second protrusion 132 of the second sidewall 112 is inserted into the second recess 232 of the second fixing part 220, and the second fixing part 220 and the peripheral wall part 110 are engaged with each other. The rear wall part 250 contacts the rear B-side end of the peripheral wall part 110, and the opening 110X of the peripheral wall part 110 is blocked by the rear wall part 250. The first protrusion 131 and the first recess 231 are included in the first locking mechanism 31. The second protrusion 132 and the second recess 232 are included in the second locking mechanism 32.

[0064] A substrate 5 is disposed inside the protective cover 100. A multi-core cable 2 passes through the through hole 250X. The front F-side end of the multi-core cable 2 is located inside the protective cover 100. Inside the protective cover 100, the outer sheath of the multi-core cable 2 is peeled off, and at the peeled-off portion, the arrangement of the plurality of wires 21 contained in the multi-core cable 2 is organized by the molding part 22. Furthermore, the plurality of wires 21 are connected to the substrate 5 on the front F-side of the molding part 22.

[0065] The first connector 3 has a connector plug 6 inserted into a through hole 120X in the front wall portion 120. The connector plug 6 is connected to the substrate 5 within the protective cover 100.

[0066] The substrate 5 has: a plurality of first pads (not shown) that are connected to a plurality of wires 21; second pads (not shown) that are connected to a connector plug 6; and wiring that connects the plurality of first pads and the plurality of second pads.

[0067] On side B behind the molding section 22, the multi-core cable 2 is as follows: Figure 12 As shown, when viewed in a cross-section perpendicular to the FB direction, it is positioned between the first fixing part 210 and the second fixing part 220. Furthermore, the multi-core cable 2 is supported near the front end 212A of the upper plate 212, near the front end 213A of the lower plate 213, near the front end 222A of the upper plate 222, and near the front end 223A of the lower plate 223. That is, when viewed in a cross-section perpendicular to the FB direction, the first fixing part 210 supports the multi-core cable 2 at two locations, and the second fixing part 220 supports the multi-core cable 2 at two locations.

[0068] An adhesive may be provided between the first fixing part 210 and the peripheral wall part 110, or between the second fixing part 220 and the peripheral wall part 110. Alternatively, an adhesive may be provided between the front ends 212A, 213A, 222A, and 223A and the multi-core cable 2.

[0069] For example, polycarbonate (PC) can be used as the material for the protective cover 100. For example, polyvinyl chloride (PVC) or thermoplastic elastomer can be used as the material for the strain relief section 200. Preferably, the first elastic modulus of the material of the protective cover 100 is higher than the second elastic modulus of the material of the strain relief section 200. The purpose is that the strain relief section 200 is more easily deformable than the protective cover 100 and can easily follow the deformation of the multi-core cable 2.

[0070] In this embodiment, the first connector 3 and the second connector 4 each have a protective cover 100 and a strain relief portion 200. The strain relief portion 200 has a rear wall portion 250 with a through hole 250X for inserting a multi-core cable 2. Therefore, it is possible to ensure flexibility through the strain relief portion 200 and ensure strength through the protective cover 100. Furthermore, the peripheral wall portion 110 of the protective cover 100 and the first fixing portion 210 of the strain relief portion 200 are engaged with each other by a first snap-fit ​​mechanism 31, and the peripheral wall portion 110 and the second fixing portion 220 are engaged with each other by a second snap-fit ​​mechanism 32. Therefore, the protective cover 100 and the strain relief portion 200 can be securely joined. Thus, even if stress is applied to the multi-core cable in the direction of pull-out from the connector, separation between the protective cover 100 and the strain relief portion 200 can be suppressed. Furthermore, the first fixing part 210 supports two points of the multi-core cable 2, and the second fixing part 220 supports two points of the multi-core cable 2. Therefore, positional displacement of the multi-core cable 2 within the first connector 3 and the second connector 4 can be suppressed. Therefore, even if bending stress is applied to the multi-core cable 2, breakage of the multi-core cable 2 within the first connector 3 and the second connector 4 can be suppressed.

[0071] A first protrusion 131 and a second protrusion 132 are provided in the peripheral wall portion 110, a first recess 231 is provided in the first fixing portion 210, and a second recess 232 is provided in the second fixing portion 220. Therefore, the peripheral wall portion 110 and the first fixing portion 210 and the second fixing portion 220 are firmly joined together.

[0072] When viewed in a cross-section perpendicular to the FB direction, the first fixing part 210 and the second fixing part 220 have a U-shaped form. Therefore, the first fixing part 210 can easily support the multi-core cable at two points, and the second fixing part 220 can easily support the multi-core cable at two points.

[0073] The opening 110X of the peripheral wall portion 110 is blocked by the rear wall portion 250, thereby preventing foreign objects from entering the first connector 3 and the second connector 4 from the outside.

[0074] A substrate 5, which is connected to one end of the multi-core cable 2, is provided inside the protective cover 100, so that signals transmitted via the multi-core cable 2 can be routed on the substrate 5.
