[0029] [Description of embodiments of this disclosure]

[0030] First, the implementation methods of this disclosure are listed and explained.

[0031] The connector disclosed herein,

[0032] (1) The device comprises: a terminal component for connection to the front end of an electrical wire; and a housing having a terminal receiving portion, wherein the electrical wire extends from the rear surface of the housing to the outside of the housing when the terminal component and the front end of the electrical wire are received in the terminal receiving portion. The terminal receiving portion is configured to include a retaining portion forming a U-shaped cross-section and a cover portion formed by a component integral with the retaining portion. The cover portion includes: a plate-shaped covering portion covering the opening of the retaining portion; and an elastically compressed portion protruding from the plate-shaped covering portion into the interior of the terminal receiving portion, which can be elastically deformed by pressure from the electrical wire. According to the structure of this disclosure, when the electrical wire in the retaining portion shifts towards the cover portion, the elastically compressed portion elastically deforms by pressure from the electrical wire, so the stress generated in the cover portion is distributed to the plate-shaped covering portion and the elastically compressed portion. If the deformation of the cover portion becomes large, the cover portion may detach from the retaining portion. In view of this, by dispersing the stress generated in the cover portion, the maximum deformation of the cover portion is suppressed, so the cover portion remains in a state of being installed in the retaining portion. According to this disclosure, it is possible to prevent the cover from detaching from the retaining part due to the pressing pressure exerted on the cover by the wire.

[0033] (2) Preferably, the retaining portion has a base opposite to the plate-shaped cover portion and a pair of sidewall portions extending from both sides of the base portion toward the plate-shaped cover portion. The elastically pressable portion is arranged along the sidewall portions, and when the elastically pressable portion is elastically deformed by the pressing force from the wire, the elastically pressable portion presses against the sidewall portions. According to this structure, when the pressing force from the wire acts on the elastically pressable portion, the cover portion is pressed away from the base portion, but the frictional resistance generated between the elastically pressable portion and the sidewall portions prevents the cover portion from shifting away from the base portion.

[0034] (3) In (2), preferably, the contact area of ​​the wire in the elastic pressure-bearing part is formed by an inclined surface that is inclined relative to the direction orthogonal to the plate-shaped covering part. According to this structure, when the wire shifts in the direction orthogonal to the plate-shaped covering part and presses against the inclined surface, a portion of the pressing force exerted by the wire on the elastic pressure-bearing part is transformed into a component force in the direction toward the side wall by the inclination of the inclined surface. The greater the displacement of the wire, the greater the elastic deformation of the elastic pressure-bearing part. However, when the elastic deformation of the elastic pressure-bearing part increases to a certain extent, the elastic pressure-bearing part abuts against the side wall, so the elastic deformation of the elastic pressure-bearing part does not increase further. Therefore, the stress generated in the elastic pressure-bearing part can be suppressed.

[0035] (4) In (2) or (3), preferably, while the elastically pressed portion is pressed against the sidewall portion, the wire remains in a state where it is not in contact with the plate-shaped covering portion. According to this structure, because the pressing force from the wire does not directly act on the plate-shaped covering portion, the stress generated in the plate-shaped covering portion is reduced, and the elastic deformation of the plate-shaped covering portion is suppressed. Because the deformation of the plate-shaped covering portion is suppressed, the cover is less likely to fall off.

[0036] (5) Preferably, when viewed from the rear, the elastic pressure-bearing portion forms a wedge shape with a narrow width at its apex in the protruding direction protruding from the plate-shaped cover. According to this structure, the component of the stress generated in the elastic pressure-bearing portion during pressure from the wire, in the direction orthogonal to the protruding direction of the elastic pressure-bearing portion near the contact point with the wire, is smaller at the base end of the protruding direction than at the apex. Therefore, the component of the force generated by the plate-shaped cover at the base end of the protruding direction of the elastic pressure-bearing portion is also suppressed, preventing the cover from falling off due to deformation of the plate-shaped cover.

[0037] (6) Preferably, when viewed from the rear, the pair of elastic pressure-bearing portions are arranged symmetrically about an imaginary axis of symmetry orthogonal to the plate-shaped cover. When the wire moves towards the plate-shaped cover, if the wire's movement path deviates towards one of the elastic pressure-bearing portions or the wire twists, the load on the connection to the terminal component may increase. As a countermeasure, the pair of elastic pressure-bearing portions are symmetrical about the imaginary axis of symmetry, preventing the wire from approaching one of the elastic pressure-bearing portions or twisting. This suppresses the load on the connection between the terminal component and the wire.

[0038] [Details of the embodiments of this disclosure]

[0039] [Example 1]

[0040] Reference Figures 1-9 Embodiment 1, which embodies this disclosure, is described below. Furthermore, the invention is not limited to these illustrations, but is shown by the claims, encompassing all modifications within the meaning and scope of the claims. In this embodiment 1, regarding the front-back direction, Figures 1-4 The positive direction of the X-axis is defined as forward. Regarding the left and right directions, [the following is a separate section:] Figures 1-3 In equations 5-9, the positive direction of the Y-axis is defined as the right. The left-right direction and the width direction are used synonymously. Regarding the up-down direction, ... Figures 1-9 The positive direction of the Z-axis is defined as upward. The vertical and vertical directions are used synonymously.

[0041] In this embodiment 1, connector A has a shielding function, relative to the opposite connector B (see figure) mounted on the lower surface of the circuit board (not shown). Figure 1 It fits from below. The counterpart connector B has a shielding function, with a counterpart housing H and multiple counterpart shield terminals T.

[0042] Connector A connects a housing 10 (refer to) Figure 1 and Figure 2 Multiple (six in this embodiment 1) shielding terminals 50, 51 (refer to) Figure 3 ) and an unshielded terminal 66 (see reference) Figure 3 The housing 10 is constructed by assembling an outer housing 11 and an inner housing 12 made of synthetic resin. Figure 2 As shown, the outer casing 11 is a single component having a frame portion 13 and a plurality of cylindrical fitting portions 24 disposed adjacent to the front of the frame portion 13. The frame portion 13 has a horizontal upper wall portion 14 that oriented in the vertical direction in the thickness direction, and a pair of outer wall portions 15 extending downward from the left and right side edges of the upper wall portion 14.

[0043] like Figure 5 As shown, the central portion of the upper wall portion 14 in the width direction functions as a plate-shaped first base portion 16 with the thickness direction being vertical. The upper wall portion 14 has three first side wall portions 17 arranged in the width direction with the thickness direction facing the width direction. The three first side wall portions 17 are shaped to protrude downward from the central position in the width direction of the first base portion 16 and the two ends in the width direction. A pair of first side wall portions 17 located on both sides in the width direction are connected to the inner surface of the outer wall portion 15 to form a pair of first step portions 18. A first retaining portion 19 is formed by a part of the first base portion 16 and two adjacent first side wall portions 17 on the left and right. The frame portion 13 has a pair of first retaining portions 19, and the pair of first retaining portions 19 share a first side wall portion 17 located in the center in the width direction, arranged on the left and right sides.

[0044] A second step 20 is formed at the center of the inner side surface of the left and right outer wall portions 15 in the height direction. For example... Figure 5 As shown, the second step portion 20 is located below the first step portion 18 and is recessed towards the outer wall portion 15 compared to the first step portion 18. First locking holes 21 are formed on both the left and right outer wall portions 15 (see reference). Figure 2 , Figure 5 ), second keyhole 22 (refer to) Figure 2 , Figure 6 ) and the third keyhole 23 (refer to Figure 2 , Figure 7 ).

[0045] Multiple cylindrical fitting portions 24 form a cylindrical shape with the axis pointing vertically. The multiple cylindrical fitting portions 24 are arranged in both the front-to-back and left-to-right directions. For example... Figure 4As shown, the lower end of the internal space of each cylindrical fitting portion 24 communicates with the internal space of the frame portion 13. The plurality of cylindrical fitting portions 24 fit into the opposite side housing H of the opposite side connector B from below.

[0046] The inner shell 12 is made of synthetic resin, such as Figure 2 , 4 As shown in Figure 7, the upper component 25, the lower component 30, and the cover 40 are assembled in an overlapping manner. The inner shell 12 is assembled to the outer shell 11 in a state of being housed within the frame portion 13.

[0047] The upper member 25 is a single component having a second base 26 and three second sidewall portions 27. The second base 26 is plate-shaped with its thickness direction oriented vertically. The three second sidewall portions 27 are arranged with their thickness direction oriented horizontally and are spaced apart in the horizontal direction. The three second sidewall portions 27 protrude downward from the center position and both ends of the second base 26 in the width direction. A second retaining portion 28 is formed by a portion of the second base 26 and two adjacent second sidewall portions 27 on the left and right sides. The upper member 25 has a pair of second retaining portions 28, which share a second sidewall portion 27 and are arranged horizontally. A pair of upper locking protrusions 29 are formed on the left and right outer surfaces of the upper member 25.

[0048] The lower member 30 is a single component having a wide base 31, a narrow base 32 narrower than the wide base 31, three thick-walled sidewall portions 33, and one thin-walled sidewall portion 34. The wide base 31 and the narrow base 32 form a plate with the thickness direction oriented vertically. The wide base 31 extends in the width direction from the left end of the lower member 30 to a position slightly to the right of the center of the lower member 30 in the width direction. The narrow base 32 extends in the width direction from the right end of the wide base 31 to the right end of the lower member 30. The narrow base 32 is positioned lower than the wide base 31.

[0049] Three thick-walled sidewall portions 33 and one thin-walled sidewall portion 34 form a plate shape with the thickness direction facing left and right, and are arranged at intervals in the left and right direction. The thin-walled sidewall portion 34 is disposed between the thick-walled sidewall portion 33 at the left end and the thick-walled sidewall portion 33 at the center in the left and right direction. The three thick-walled sidewall portions 33 protrude downward from both ends of the wide-width base 31 in the width direction and from the right end of the narrow-width base 32. The thin-walled sidewall portion 34 protrudes downward from the center of the wide-width base 31 in the width direction. The wide-width base 31 is the region between the thick-walled sidewall portion 33 at the left end and the thick-walled sidewall portion 33 at the center in the left and right direction. The narrow-width base 32 is the region between the thick-walled sidewall portion 33 at the center in the left and right direction and the thick-walled sidewall portion 33 at the right end.

[0050] like Figures 5-9 As shown, a wide-width retaining portion 35 is formed by a portion of the wide-width base 31 and a thick-walled sidewall portion 33 and a thin-walled sidewall portion 34 protruding from the wide-width base 31. The lower member 30 has a pair of wide-width retaining portions 35, which share a thin-walled sidewall portion 34 and are arranged left and right. A narrow-width retaining portion 36 is formed by a narrow-width base 32, a thick-walled sidewall portion 33 protruding from the right end of the wide-width base 31, and a thick-walled sidewall portion 33 protruding from the right end of the narrow-width base 32. The right-side wide-width retaining portion 35 and the narrow-width retaining portion 36 are arranged left and right in a manner that share the right-side thick-walled sidewall portion 33. A pair of lower locking protrusions 37 are formed on the left and right outer surfaces of the lower member 30.

[0051] The cover 40 is a single component having a cover portion 41 and a pair of left and right locking retaining walls 46. The cover portion 41 is formed by a plate-shaped covering portion 42 and three pairs of elastic pressure-bearing portions 43 protruding upward from the plate-shaped covering portion 42. The plate-shaped covering portion 42 is formed into a flat plate with its thickness direction oriented vertically. The plate-shaped covering portion 42 extends across the entire width of the cover 40 from the left end to the right end. The pair of locking retaining walls 46 are plate-shaped extending upward from the left and right side edges of the plate-shaped covering portion 42. Cover-side locking protrusions 47 are formed on the outer surfaces of the two locking retaining walls 46.

[0052] like Figure 2 As shown, the elastic pressure-receiving portion 43 is formed in the form of a slender rib in the front-to-back direction and is disposed at the rear end of the cover 40. The rear end face of the elastic pressure-receiving portion 43 and the rear end face of the cover 40 are flush and connected. Figure 8 , 9 As shown, when viewed from the rear, the elastic pressure-bearing portion 43 is a right-angled triangle, i.e., a wedge shape whose width gradually decreases towards the protruding direction from the plate-shaped cover portion 42. The elastic pressure-bearing portion 43 has a friction surface 44 and a pressure-bearing surface 45. The friction surface 44 is a vertical plane, i.e., a plane parallel to the thickness direction of the plate-shaped cover portion 42. The pressure-bearing surface 45 is a flat, inclined plane extending in a direction inclined relative to the vertical direction, i.e., a plane inclined relative to the thickness direction of the plate-shaped cover portion 42. When the elastic pressure-bearing portion 43 is subjected to a downward (inclined relative to the pressure-bearing surface 45) pressing force on the pressure-bearing surface 45, it elastically deforms by tilting towards the friction surface 44. Because the elastic pressure-bearing portion 43 forms a wedge shape that narrows upwards, the elastic deformation of the elastic pressure-bearing portion 43 is greatest at its upper end and decreases towards its lower end. The lower end of the elastically compressed part 43 exhibits almost no elastic deformation.

[0053] A pair of elastically compressed portions 43 are housed in the wide-width retaining portion 35. A pair of elastically compressed portions 43 are also housed in the narrow-width retaining portion 36. The two pairs of elastically compressed portions 43 are arranged in a positional relationship that is spaced apart in the width direction. When viewed from the rear, the pair of elastically compressed portions 43 are symmetrical about an imaginary axis V (see reference) parallel to the thickness direction of the plate-shaped covering portion 42. Figure 9 The shape is symmetrical from left to right. Pairs of elastic pressure-bearing parts 43 are arranged such that the pressure-bearing surfaces 45 are opposite each other in the width direction. Three pairs of elastic pressure-bearing parts 43 are arranged in the width direction.

[0054] like Figure 3 , 4 As shown, the plurality of shielding terminals 50, 51 form an L-shaped bend when viewed from the side. The plurality of shielding terminals 50, 51 includes three large-diameter shielding terminals 50 and three small-diameter shielding terminals 51. The shielding terminals 50, 51 have an inner conductor 52 bent into an L-shape, a dielectric body 53 housing the inner conductor 52, and an outer conductor 54 surrounding the dielectric body 53. The outer conductor 54 is formed by combining a first shell 55 forming an L-shape and a second shell 56 having a crimping portion 57.

[0055] The large-diameter shielded terminal 50 is electrically connected to the front end of the large-diameter shielded wire 60, which is made of coaxial cable. The small-diameter shielded terminal 51 is electrically connected to the front end of the small-diameter shielded wire 61, which is made of coaxial cable. The large-diameter shielded wire 60 and the small-diameter shielded wire 61 have a core wire 62, an insulating sheath 63 surrounding the core wire 62, a shielding layer 64 surrounding the insulating sheath 63, and a sheath 65 surrounding the shielding layer 64. The rear end of the core wire 62 is fixedly mounted with an inner conductor 52. The shielding layer 64 has a crimped portion 57 electrically fixedly mounted with an outer conductor 54.

[0056] like Figure 3 As shown, the unshielded terminal 66 forms an L-shaped bend when viewed from the side. The unshielded terminal 66 is electrically connected to the front end of the unshielded sheathed wire 67. Figure 8 , 9 As shown, the sheathed wire 67 has a core wire 68 and an insulating sheath 69 that surrounds the core wire 68.

[0057] The assembly steps of connector A in this embodiment 1 are explained. First, two large-diameter shielded terminals 50 are installed on the outer housing 11, which is in a state where the inner housing 12 is not assembled. At this time, the upward-facing front end of the large-diameter shielded terminal 50 is housed in the cylindrical fitting portion 24, and the portion of the large-diameter shielded terminal 50 surrounded by the second housing 56 is housed in the first holding portion 19.

[0058] Next, the upper member 25 is assembled into the frame portion 13 from below the outer casing 11. The upper member 25 is locked in the assembled state by having the left and right ends of the second base portion 26 abut against the first step portion 18 and the upper locking protrusion 29 engage with the first locking hole 21. When the upper member 25 is assembled into the outer casing 11, the opening on the lower surface of the first retaining portion 19 is closed by the second base portion 26, thereby forming a pair of left and right first terminal storage portions 71 (see reference). Figure 4 , 6 The front end of the large-diameter shielded terminal 50 and the large-diameter shielded wire 60 are housed in the first terminal housing 71. The large-diameter shielded wire 60 extends rearward and outward from the rear surface of the housing 10.

[0059] Next, a large-diameter shielding terminal 50 and a small-diameter shielding terminal 51 are installed on the housing 11 and the upper member 25. At this time, the upward-facing front ends of each shielding terminal 50, 51 are housed in the cylindrical fitting portion 24, and the portions of each shielding terminal 50, 51 that are surrounded by the second housing 56 are housed in the second holding portion 28.

[0060] Next, the lower member 30 is assembled into the frame portion 13 from below the outer casing 11. The lower member 30 is locked in the assembled state by having the left end of the wide base 31 and the right end of the narrow base 32 abut against the second step portion 20, and the lower locking protrusion 37 engage with the second locking hole 22. When the lower member 30 is assembled into the outer casing 11, the opening on the lower surface of the second retaining portion 28 is closed by the wide base 31, thereby forming a pair of left and right second terminal storage portions 72 (see reference). Figure 4 , 6 The first second terminal housing 72 houses the front ends of the large-diameter shielded terminal 50 and the large-diameter shielded wire 60. The large-diameter shielded wire 60 extends rearward and outward from the rear surface of the housing 10. The second second terminal housing 72 houses the front ends of the small-diameter shielded terminal 51 and the small-diameter shielded wire 61. The small-diameter shielded wire 61 extends rearward and outward from the rear surface of the housing 10.

[0061] Next, two small-diameter shielded terminals 51 and one unshielded terminal 66 are installed on the housing 11 and the lower member 30. At this time, the upward-facing front ends of the small-diameter shielded terminals 51 and the unshielded terminal 66 are housed in the cylindrical fitting portion 24. The portion of the small-diameter shielded terminal 51 surrounded by the second housing 56 is housed in the wide-width retaining portion 35. The unshielded terminal 66 is housed in the narrow-width retaining portion 36.

[0062] Next, the cover 40 is assembled from below onto the housing 11, and the plate-shaped covering portion 42 of the cover 40 closes the opening on the lower surface of the frame portion 13. The assembled cover 40 is locked in the assembled state relative to the housing 11 by abutting against the lower surface of the lower member 30 and by engaging the cover-side locking protrusion 47 with the third locking hole 23. When the cover 40 is installed on the housing 11, the assembly of connector A is completed.

[0063] When the cover 40 is assembled onto the outer casing 11, the opening on the lower surface of the wide-width retaining portion 35 is closed by the plate-shaped covering portion 42, thereby forming a pair of wide-width terminal storage portions 73 on the left and right (see reference). Figure 8 , 9 The front ends of the small-diameter shielded terminal 51 and the small-diameter shielded wire 61 are housed within the wide-width terminal housing 73. The small-diameter shielded wire 61 extends rearward and outward from the rear surface of the housing 10. The opening on the lower surface of the narrow-width retaining portion 36 is closed by the plate-shaped cover portion 42, thereby forming the narrow-width terminal housing 74 (see reference). Figure 8 , 9 The unshielded terminal 66 and the front end of the covered wire 67 are housed within the narrow-width terminal housing 74. The covered wire 67 extends rearward and outward from the rear surface of the housing 10.

[0064] With the cover 40 assembled onto the outer casing 11, a pair of resilient pressure-bearing portions 43 are housed within each of the two wide retaining portions 35 and one narrow retaining portion 36. Within the two wide retaining portions 35, one resilient pressure-bearing portion 43 is arranged along the thick-walled sidewall portion 33, and the other resilient pressure-bearing portion 43 is arranged along the thin-walled sidewall portion 34. The portion of the small-diameter shielded wire 61 housed within the wide retaining portions 35 and the portion extending towards the rear of the casing 10 are straight and not bent, as shown in the image. Figure 8 As shown, the small-diameter shielded wire 61 and the elastic compression portion 43 are positioned apart by a gap rather than in contact with each other. Therefore, the elastic compression portion 43 does not elastically deform. The small-diameter shielded wire 61 and the plate-shaped covering portion 42 are also positioned apart by a gap rather than in contact with each other. In the free state where the elastic compression portion 43 does not elastically deform, the friction surface 44 of the elastic compression portion 43 is positioned opposite to the thick-walled sidewall portion 33 and the thin-walled sidewall portion 34 in the width direction with a slight gap between them.

[0065] Within the narrow-width retaining portion 36, a pair of elastically compressed portions 43 are arranged along the thick-walled sidewall portion 33. In a straight line state, where the portion of the covered wire 67 housed within the narrow-width retaining portion 36 and the portion extending rearwards towards the outside of the housing 10 are not bent, the covered wire 67 and the elastically compressed portions 43 are positioned apart by a gap rather than in contact. Therefore, the elastically compressed portions 43 do not elastically deform. The covered wire 67 and the plate-like covering portion 42 are also positioned apart by a gap rather than in contact. In the free state where the elastically compressed portions 43 are not elastically deformed, the friction surfaces 44 of the elastically compressed portions 43 are positioned opposite each other in the width direction, maintaining a slight gap relative to the thick-walled sidewall portion 33.

[0066] like Figure 4 As shown, when the small-diameter shielded wire 61 extending from the wide-width terminal storage section 73 is stretched downwards and bent, as... Figure 9 As shown, the small-diameter shielded wire 61 is in contact with the pressure-receiving surfaces 45 of the left and right elastic pressure-receiving portions 43. When the small-diameter shielded wire 61 moves further downward from this state, the downward pressing force from the small-diameter shielded wire 61 acts on the cover 40. Here, the pressure-receiving surfaces 45 are set to an inclined orientation relative to the pressing direction of the pressing force, so a portion of the downward pressing force from the small-diameter shielded wire 61 becomes a component force in the left and right directions relative to the elastic pressure-receiving portions 43. Through this component force, the elastic pressure-receiving portions 43 elastically deform in the width direction. In the state of elastic deformation of the elastic pressure-receiving portions 43, the small-diameter shielded wire 61 is not in contact with the upper surface of the plate-shaped cover portion 42. Therefore, the stress generated in the cover portion 41 is not concentrated in the plate-shaped cover portion 42, but is dispersed to the elastic pressure-receiving portions 43.

[0067] When the elastically compressed portion 43 elastically deforms in the width direction, the friction surface 44 presses against the thick-walled sidewall portion 33 and the thin-walled sidewall portion 34, thus generating frictional resistance between the friction surface 44 and the thick-walled sidewall portion 33, and between the friction surface 44 and the thin-walled sidewall portion 34. This frictional resistance is the force that counteracts the downward pressing pressure exerted on the cover portion 41 by the small-diameter shielded wire 61, thus inhibiting the plate-shaped cover portion 42 from moving downward or elastically deforming in a downward bulging manner. With the friction surface 44 pressing against the thick-walled sidewall portion 33 and the thin-walled sidewall portion 34, the small-diameter shielded wire 61 does not contact the upper surface of the plate-shaped cover portion 42.

[0068] Compared to the thick-walled sidewall 33, the thin-walled sidewall portion 34 has lower rigidity relative to external forces in the left-right direction, and therefore may deform in a retracting manner relative to the pressing force in the width direction received from the elastically compressed portion 43. However, a pair of elastically compressed portions 43 exist on both sides of the thin-walled sidewall portion 34, clamping it between them. When the two small-diameter shielded wires 61 extending from the two large width-holding portions 35 are bound together, for example, with other wires 60 and 67, the two small-diameter shielded wires 61 move downward as a single unit. Therefore, the thin-walled sidewall portion 34 is pressed down by the pair of elastically compressed portions 43 from the left and right sides, and thus does not deform in the width direction.

[0069] Furthermore, similar to the case of the small-diameter shielded wire 61, when the covered wire 67, which is extended from the narrow-width terminal housing 74, is stretched downwards, the downward pressing force from the covered wire 67 acts on the cover 40. Because a portion of the downward pressing force from the covered wire 67 becomes a component force in the left-right direction relative to the elastic pressure portion 43, the elastic pressure portion 43 elastically deforms in the width direction. In the state of elastic deformation of the elastic pressure portion 43, the covered wire 67 does not contact the upper surface of the plate-shaped cover portion 42. Therefore, the stress generated in the cover portion 41 is dispersed. When the elastic pressure portion 43 elastically deforms in the width direction, the friction surface 44 presses against the thick-walled sidewall portion 33, generating frictional resistance between the friction surface 44 and the thick-walled sidewall portion 33. Through this frictional resistance, the downward displacement of the plate-shaped cover portion 42 or its elastic deformation in a downward bulging manner can be suppressed. With the friction surface 44 pressed against the thick-walled sidewall portion 33, the covered wire 67 does not contact the upper surface of the plate-shaped covering portion 42.

[0070] The connector A of this embodiment 1 includes: a small-diameter shielded terminal 51 connected to the front end of a small-diameter shielded wire 61; an unshielded terminal 66 connected to the front end of a covered wire 67; and a housing 10 having a wide-width terminal receiving portion 73 and a narrow-width terminal receiving portion 74. With the small-diameter shielded terminal 51 and the front end of the small-diameter shielded wire 61 housed in the wide-width terminal receiving portion 73, the small-diameter shielded wire 61 extends from the rear surface of the housing 10 to the outside of the housing 10. With the unshielded terminal 66 and the front end of the covered wire 67 housed in the narrow-width terminal receiving portion 74, the covered wire 67 extends from the rear surface of the housing 10 to the outside of the housing 10.

[0071] The wide-width terminal receiving portion 73 is configured to include a wide-width retaining portion 35 with a U-shaped cross-section and a cover portion 41 composed of a component separate from the wide-width retaining portion 35. The cover portion 41 is mounted on the wide-width retaining portion 35. The narrow-width terminal receiving portion 74 is configured to include a narrow-width retaining portion 36 with a U-shaped cross-section and a cover portion 41 composed of a component separate from the narrow-width retaining portion 36. The cover portion 41 includes a plate-shaped covering portion 42 and an elastically pressure-bearing portion 43. The cover portion 41 is mounted on the narrow-width retaining portion 36. The plate-shaped covering portion 42 covers the openings on the lower surfaces of the wide-width retaining portion 35 and the narrow-width retaining portion 36. The elastically pressure-bearing portion 43 protrudes from the plate-shaped covering portion 42 into the interior of the wide-width terminal receiving portion 73 or the narrow-width terminal receiving portion 74, and can be elastically deformed by pressure from the small-diameter shielded wire 61 or from the sheathed wire 67.

[0072] According to the above structure, when the small-diameter shielded wire 61 in the wide-width retaining portion 35 shifts towards the cover portion 41, the pressing pressure from the small-diameter shielded wire 61 causes the elastic pressure-bearing portion 43 to elastically deform, thus dispersing the stress generated in the cover portion 41 to the plate-shaped covering portion 42 and the elastic pressure-bearing portion 43. When the covered wire 67 in the narrow-width retaining portion 36 shifts towards the cover portion 41, the pressing pressure from the covered wire 67 causes the elastic pressure-bearing portion 43 to elastically deform, thus dispersing the stress generated in the cover portion 41 to the plate-shaped covering portion 42 and the elastic pressure-bearing portion 43. This suppresses stress concentration in the cover portion 41 caused by the pressing pressure from the small-diameter shielded wire 61 or the covered wire 67. When stress in the cover portion 41 is concentrated at a specific location, the elastic deformation of that location increases, and therefore the cover-side locking protrusion 47 of the cover portion 41 may detach from the third locking hole 23 of the outer casing 11. At this time, a pressing force from the small-diameter shielded wire 61 is applied to the cover 41, which may cause the cover 41 to detach from the wide-width retaining portion 35 and the narrow-width retaining portion 36. As a countermeasure, the stress generated in the cover 41 is dispersed to suppress the maximum deformation of the cover 41, so the cover 41 is kept in the state of being installed in the wide-width retaining portion 35 and the narrow-width retaining portion 36. Therefore, according to this embodiment 1, it is possible to prevent the cover 40 from detaching from the outer casing 11 (wide-width retaining portion 35 and narrow-width retaining portion 36) due to the downward pressing force exerted on the cover 41 by the small-diameter shielded wire 61.

[0073] The wide-width retaining portion 35 has a wide-width base 31 opposite to the plate-shaped cover portion 42, and a pair of sidewall portions (thick-walled sidewall portion 33 and thin-walled sidewall portion 34) extending from both sides of the wide-width base 31 toward the plate-shaped cover portion 42. The elastic pressure-bearing portion 43 is arranged along the thick-walled sidewall portion 33 or the thin-walled sidewall portion 34. When the elastic pressure-bearing portion 43 is elastically deformed by the pressing force from the small-diameter shielded wire 61, the elastic pressure-bearing portion 43 presses against the thick-walled sidewall portion 33 or the thin-walled sidewall portion 34. When the pressing force from the small-diameter shielded wire 61 acts on the elastic pressure-bearing portion 43, the cover portion 41 is pressed away from the wide-width base 31, but the frictional resistance generated between the elastic pressure-bearing portion 43 and the thick-walled sidewall portion 33 or the thin-walled sidewall portion 34 prevents the cover portion 41 from shifting away from the wide-width base 31.

[0074] The narrow-width retaining portion 36 has a narrow-width base 32 opposite to the plate-shaped cover portion 42, and a pair of thick-walled sidewall portions 33 extending from both sides of the narrow-width base 32 toward the plate-shaped cover portion 42. The elastic pressure-bearing portion 43 is arranged along the thick-walled sidewall portions 33. When the elastic pressure-bearing portion 43 is elastically deformed by the pressing force from the covered wire 67, the elastic pressure-bearing portion 43 presses against the thick-walled sidewall portions 33. When the pressing force from the covered wire 67 acts on the elastic pressure-bearing portion 43, the cover portion 41 is pressed away from the narrow-width base 32, but the frictional resistance generated between the elastic pressure-bearing portion 43 and the thick-walled sidewall portions 33 prevents the cover portion 41 from shifting away from the narrow-width base 32.

[0075] The pressure-receiving surface 45, which serves as the contact area between the small-diameter shielded wire 61 and the covered wire 67 in the elastic pressure-receiving part 43, is formed by an inclined surface that is tilted relative to the vertical direction orthogonal to the plate-shaped covering part 42. According to this structure, when the small-diameter shielded wire 61 or the covered wire 67 shifts downwards orthogonal to the plate-shaped covering part 42 and presses against the pressure-receiving surface 45, a portion of the pressing force exerted by the small-diameter shielded wire 61 or the covered wire 67 on the elastic pressure-receiving part 43 becomes a component force in the width direction toward the thick-walled sidewall part 33 or the thin-walled sidewall part 34 due to the inclination of the pressure-receiving surface 45. During the shifting process of the small-diameter shielded wire 61 or the covered wire 67, the elastic pressure-receiving part 43 can be reliably pressed against the thick-walled sidewall part 33 or the thin-walled sidewall part 34. Furthermore, as the downward displacement of the small-diameter shielded wire 61 increases, the elastic deformation of the elastic compression portion 43 in the left-right direction also increases. However, when the elastic deformation of the elastic compression portion 43 increases to a certain extent, the elastic compression portion 43 abuts against the thick-walled sidewall portion 33 and the thin-walled sidewall portion 34, so the elastic deformation of the elastic compression portion 43 does not increase further. Therefore, the stress generated in the elastic compression portion 43 can be suppressed.

[0076] With the elastically compressed portion 43 pressed against the thick-walled sidewall portion 33 or the thin-walled sidewall portion 34, the small-diameter shielded wire 61 or the covered wire 67 remains in a state where it does not contact the plate-shaped covering portion 42. According to this structure, the pressing force from the small-diameter shielded wire 61 or the covered wire 67 does not directly act on the plate-shaped covering portion 42, thus reducing the stress generated in the plate-shaped covering portion 42 and suppressing the elastic deformation of the plate-shaped covering portion 42. Because the deformation of the plate-shaped covering portion 42 is suppressed, the cover portion 41 is less likely to detach from the wide-width retaining portion 35 and the narrow-width retaining portion 36.

[0077] When viewed from the rear, the pair of resilient pressure-bearing portions 43 are arranged symmetrically about an imaginary axis of symmetry V orthogonal to the plate-shaped cover portion 42. When the small-diameter shielded wire 61 moves towards the plate-shaped cover portion 42, and its movement path deviates towards one of the resilient pressure-bearing portions 43 or it twists, the load on the connection between the small-diameter shielded wire 61 and the crimping portion 57 of the small-diameter shielded terminal 51 may increase. Similarly, when the covered wire 67 moves towards the plate-shaped cover portion 42, and its movement path deviates towards one of the resilient pressure-bearing portions 43 or it twists, the load on the connection between the covered wire 67 and the unshielded terminal 66 may also increase. As a countermeasure, the pair of resilient pressure-bearing portions 43 are arranged in a symmetrical shape and configuration about the imaginary axis of symmetry V to prevent the small-diameter shielded wire 61 or the covered wire 67 from approaching or twisting towards one of the resilient pressure-bearing portions 43. Therefore, it is possible to suppress the load generated at the connection between the small-diameter shielded terminal 51 and the small-diameter shielded wire 61, or at the connection between the unshielded terminal 66 and the covered wire 67.

[0078] When viewed from the rear, the elastic pressure-bearing portion 43 forms a wedge shape with a narrow width at its tip protruding from the plate-shaped cover portion 42. According to this structure, when pressure from the small-diameter shielded wire 61 or the covered wire 67 acts on the elastic pressure-bearing portion 43, the stress generated in the elastic pressure-bearing portion 43 is uneven. That is, the component of the stress generated in the elastic pressure-bearing portion 43 in the direction orthogonal to the protruding direction (left-right direction) is smaller than the component of the stress on the protruding tip side (upper end side) of the contact portion of the small-diameter shielded wire 61 or the covered wire 67 compared to the component on the protruding tip side (upper end side). Therefore, the stress generated in the plate-shaped cover portion 42 connected to the protruding base end of the elastic pressure-bearing portion 43 is also suppressed, preventing the cover portion 41 from detaching from the wide-width retaining portion 35 and the narrow-width retaining portion 36 due to deformation of the plate-shaped cover portion 42.
