Description

[Technical Field]

[0001] The present disclosure relates to a shield receiving member and a shield connector. [Background technology]

[0002] The connector described in Patent Document 1 includes a shield receiving member (referred to as a wiring portion in Patent Document 1) that contacts the shield portion of the shielded electric wire (referred to as a shield wire in Patent Document 1). The shield receiving member sandwiches the shield portion between itself and the crimping member, and receives the fastening force of the crimping member. This shield receiving member is cylindrical and has a recess on its outer circumferential surface. The shield portion fits into the recess when the crimping member is crimped. This type of shield receiving member is also disclosed in Patent Documents 2-6. [Prior art documents] [Patent documents]

[0004] In Patent Document 1, if the shield receiving member is not continuous around the entire circumference and is bent so that both circumferential ends face each other, there is a concern that the recess will be largely interrupted in the circumferential direction between both circumferential ends. If the recess is largely interrupted in the circumferential direction in this way, the shield portion may enter the recess, and the expected improvement in wire retention force may not be achieved.

[0005] Therefore, an object of the present disclosure is to provide a shield receiving member and a shield connector that can improve the wire holding force. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The shield receiving member of the present disclosure comprises: (1) A plate-shaped main body portion extends in a circumferential direction and has both ends in the circumferential direction opposed to each other, the main body portion having an outer peripheral surface in contact with a shield portion of an electric wire and an inner peripheral surface in contact with an outer sheath of the electric wire, one end of the both ends in the circumferential direction of the main body portion has a recessed portion recessed in the circumferential direction, and the other end has a protruding portion protruding in the circumferential direction and disposed inside the recessed portion, the main body portion has a first locking portion and a second locking portion bent from the outer peripheral surface side to the inner peripheral surface side, the first locking portion and the second locking portion are , each extending in the circumferential direction from one end on the one end side to the other end on the other end side, and arranged side by side in an axial direction intersecting the circumferential direction, one end of the first locking portion being located on the bottom side of the recess, the other end of the first locking portion being located on the tip side of the protrusion, one end of the second locking portion being located closer to the opening end of the recess than the one end of the first locking portion, and the other end of the second locking portion being located closer to the base end of the protrusion than the other end of the first locking portion.

[0010] According to the above configuration, the shield portion of the electric wire can fit into the first locking portion and the second locking portion, respectively. Furthermore, the first locking portion and the second locking portion can bite into the outer sheath of the electric wire, respectively. This allows the shield receiving member to hold the electric wire. Furthermore, with the above configuration, when the protrusion is disposed inside the recess between both circumferential ends of the main body, the other end of the first locking portion and the one end of the second locking portion can be discontinuous or continuous without a significant break in the circumferential direction when viewed in the axial direction. Therefore, the above configuration can reduce or eliminate breaks in the wire retention force between both axial ends of the main body, thereby improving the wire retention force.

[0011] (2) The second locking portions are preferably disposed on both sides of the first locking portion in the axial direction. According to the above configuration, the first locking portion and each second locking portion can hold the electric wire firmly and stably.

[0012] (3) The second locking portion may have a flat surface along the axial direction on the inner peripheral surface side, and the first locking portion may have a pointed or curved protruding surface on the inner peripheral surface side. With the above configuration, the shield section can be easily inserted into the second locking section, and since the second locking sections are disposed on both sides of the first locking section in the axial direction, the shield section is stably held in the second locking section. Furthermore, the protruding surfaces of the first locking sections can firmly bite into the outer sheath, preventing the outer sheath (electric wire) from shifting position relative to the shield receiving member.

[0013] (4) The width dimension of the first locking portion in the axial direction may be smaller than the width dimension of the second locking portion in the axial direction. According to the above configuration, even if the main body portion is made smaller in the axial direction, sufficient separation space can be secured between the first locking portion and the second locking portion within the axial width of the main body portion, resulting in excellent space efficiency.

[0014] (5) The recess has the bottom in the center of the axial direction at one end of the main body, the open ends at both ends of the axial direction at one end of the main body, and is shaped to connect the bottom and the open end with a concave slope; the convex portion has the tip in the center of the axial direction at the other end of the main body, the base ends at both ends of the axial direction at the other end of the main body, and is shaped to connect the tip and the base end with a convex slope; one end of the second engaging portion is positioned in a position overlapping the concave slope when viewed from the axial direction, and the other end of the second engaging portion is positioned in a position overlapping the convex slope when viewed from the axial direction. According to the above configuration, the first locking portion and each second locking portion are arranged with good space efficiency within the axial width of the main body portion, which can contribute to making the main body portion smaller in the axial direction.

[0015] (6) A shielded connector may include a shield receiving member according to any one of (1) to (5) above, an inner conductor terminal connected to a core wire of the electric wire, a dielectric that houses the inner conductor terminal, and an outer conductor terminal that is arranged on the outer periphery of the dielectric, wherein the outer conductor terminal has a crimping portion that crimps the shield portion between the outer conductor terminal and the shield receiving member, and the first locking portion and the second locking portion are covered by the crimping portion.

[0016] According to the above configuration, the securing force of the crimping portion causes the shield portion to fit into the first and second locking portions, respectively, and the first and second locking portions can bite into the outer jacket. Therefore, even if the main body is made smaller in the axial direction, the wire retention force can be improved, which in turn contributes to making the outer conductor terminal smaller in the axial direction.

[0017] [Details of the embodiments of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. However, the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0018] <Embodiment 1> The shield receiving member 10 of the first embodiment of the present disclosure is a cylindrical member that receives and supports the shield portion 92 of the electric wire 90 and is commonly referred to as a "sleeve." The shield receiving member 10 constitutes a part of the shielded connector 60. In the following description, the left side of each drawing except for FIG. 5 is referred to as the front side with respect to the front-rear direction. The front-rear direction corresponds to the length direction of the electric wire 90 and is sometimes referred to as the axial direction. The up-down direction is based on the up-down direction in FIGS. 1 to 4. This up-down direction does not necessarily coincide with the vertical direction when the shielded connector 60 is mounted on a vehicle or the like. The circumferential direction is a direction that intersects (specifically, is perpendicular to) the axial direction and refers to the circumferential direction of the shield receiving member 10 unless otherwise specified. In the drawings, the symbol "X" indicates the front-rear direction (axial direction), and the symbol "Y" indicates the circumferential direction.

[0019] (Electric wire) The electric wire 90 is a shielded electric wire, and as shown in Fig. 1, includes a plurality of conductor wires 91, a shield portion 92 that collectively surrounds each of the conductor wires 91, and an insulating outer sheath 93 that covers the outer periphery of the shield portion 92. An insulating member 94 is disposed between each of the conductor wires 91 and the shield portion 92. In the case of the first embodiment, two conductor wires 91 are twisted together to form a twisted pair wire. Each conductor wire 91 is a coated electric wire in which a core wire 95 is covered with an insulating coating 96.

[0020] The front end portion of each conductor 91 is exposed and not covered with the shield portion 92, the outer sheath 93, and the insulating member 94. At the front end portion of each conductor 91, the insulating coating 96 is stripped away, exposing the core wire 95.

[0021] In the first embodiment, the shield portion 92 is a braided wire made by weaving conductive wires into a cylindrical shape. The front end portion of the shield portion 92 is folded back toward the outer periphery of the outer jacket 93 to form a shield tip portion 97. As shown in FIG. 2 , a shield receiving member 10 is interposed between the shield tip portion 97 and the outer jacket 93.

[0022] (shielded connector) 1, the shielded connector 60 includes a shield receiving member 10, an inner conductor terminal 50, a dielectric 40, and an outer conductor terminal 30. The structure of the shield receiving member 10 will be described in detail later.

[0023] The inner conductor terminals 50 are made of conductive metal and provided in pairs corresponding to the two conductor wires 91. The inner conductor terminals 50 are electrically connected to the core wires 95 of the conductor wires 91 and mechanically connected to the insulating coatings 96 of the conductor wires 91. The inner conductor terminals 50 also have rectangular cylindrical box portions 51 that are electrically connected to a mating inner conductor terminal (not shown).

[0024] The dielectric 40 is made of synthetic resin and is composed of a detachable first dielectric 41 and a second dielectric 42. The first dielectric 41 is disposed above the second dielectric 42 and has cavities (not shown) on both the left and right sides for accommodating the inner conductor terminals 50. The second dielectric 42 is a lid-like member that closes each of the cavities that are open downward. The dielectric 40 serves to maintain an insulating state between the inner conductor terminals 50 and the outer conductor terminal 30.

[0025] The outer conductor terminal 30 is made of a conductive metal and includes a first outer conductor terminal 31 and a second outer conductor terminal 32 disposed below the first outer conductor terminal 31. The second outer conductor terminal 32 has an enclosing portion 33 that encloses the outer periphery of the dielectric 40 and a strip-shaped extending portion 34 that extends rearward from the rear end of the lower wall of the enclosing portion 33. The enclosing portion 33 is electrically connected to a mating outer conductor terminal of a mating shielded connector (not shown). As shown in FIG. 3, the extending portion 34 is disposed on the outer periphery side of the shield tip portion 97.

[0026] As shown in Fig. 2, the first outer conductor terminal 31 has an attachment portion 35 attached to the rear portion of the second outer conductor terminal 32, and a crimping portion 36 connected to the rear of the attachment portion 35. The crimping portion 36 has a base portion 37 extending continuously from the attachment portion 35, and a plurality of barrel pieces 38 protruding from both the left and right sides of the base portion 37. As shown in Fig. 3, the barrel pieces 38 are arranged alternately in the front-to-rear direction, with three pieces arranged side by side, at each of the left and right ends of the base portion 37. The crimping portion 36 is bent into a cylindrical shape during the crimping process. The barrel pieces 38 are wrapped around the outer peripheral surfaces of the shield tip portion 97 and the extension portion 34, respectively, during the crimping process.

[0027] 1, a plurality of claws 39 are formed in a row in the circumferential direction at the rear end of the crimping portion 36. As shown in Fig. 2, each claw 39 is bent radially inward from the rear end of the base 37, and is disposed facing the shield receiving member 10 from behind.

[0028] (Shield support member) The shield receiving member 10 is made of conductive metal and has a main body 11 (see FIG. 4) that has been bent into a cylindrical shape. The main body 11 is strip-shaped and has a constant width in the front-to-rear direction. One of the two circumferential ends of the main body 11 (the left-to-right length direction in the unfolded state) has a recess 12 that is triangular in shape when viewed from the radial direction, and the other end has a protrusion 13 that is triangular in shape when viewed from the radial direction.

[0029] In a state where the main body portion 11 has been bent into a cylindrical shape, both circumferential ends face each other, and the protrusions 13 are disposed inside the recesses 12, as shown in Fig. 4. As shown in Fig. 3, the inner circumferential surface of the main body portion 11 is disposed along the outer sheath 93 of the electric wire 90 and is capable of contacting the outer sheath 93. The outer circumferential surface of the main body portion 11 is disposed along the shield tip portion 97 of the electric wire 90 and is capable of contacting the shield tip portion 97.

[0030] 5, the recess 12 has a bottom 14 at the center in the front-to-rear direction (axial direction, width direction of the main body 11) at one end of the main body 11, and has open ends 15 at both ends in the front-to-rear direction at one end of the main body 11. The recess 12 has a pair of inclined recessed surfaces 16 that extend tapered from the open ends 15 to the bottom 14.

[0031] The protruding portion 13 has a tip 17 in the center in the front-rear direction at the other end of the main body 11, and base ends 18 at both ends in the front-rear direction at the other end of the main body 11. The protruding portion 13 has a pair of convex inclined surfaces 19 that extend tapered from the respective base ends 18 to the tip 17. The opening angle of each convex inclined surface 19 and the opening angle of each concave inclined surface 16 are set to be the same.

[0032] As shown in Fig. 4, the main body 11 has a tip striking surface 21 on the outer peripheral surface of the tip 17 side of the convex portion 13, which is inclined in a direction in which the thickness decreases toward the tip 17. The main body 11 also has an opening end striking surface 22 on the outer peripheral surface of each opening end 15 side of the concave portion 12, which is inclined in a direction in which the thickness decreases toward the opening end 15. By having the opening end striking surface 22 and the tip striking surface 21 on the main body 11, the elastic reaction force at one end and the other end of the main body 11 is suppressed, making it easier to maintain the cylindrical shape of the main body 11.

[0033] The main body 11 has a first locking portion 23 and a second locking portion 24 arranged side by side in the front-to-rear direction. The second locking portions 24 are arranged in pairs on the main body 11, on both the front and rear sides of the first locking portion 23. The first locking portion 23 extends in the circumferential direction and has a serration shape (rib shape) that bends from the outer peripheral surface side to the inner peripheral surface side (radially inward) of the main body portion 11, as shown in Fig. 3. As shown in Fig. 5, the first locking portion 23 has one end 23A as a closed end at a position close to the bottom 14 of the recess 12 on one end side of the main body portion 11 in the circumferential direction. As shown in Fig. 4, the one end 23A of the first locking portion 23 is disposed circumferentially adjacent to the tip striking surface 21 on the outer peripheral surface of the main body portion 11. The first locking portion 23 has a closed end 23B at a position close to the tip 17 of the protrusion 13 on the other circumferential end side of the main body 11. As shown in FIG. 5, the other end 23B of the first locking portion 23 has a triangular convex shape when viewed from the radial direction on the inner circumferential surface side of the main body 11 so as to correspond to the tip 17 of the protrusion 13. The first locking portion 23 extends continuously and without interruption in the circumferential direction from the one end 23A to the other end 23B. As shown in FIG. 3, the first locking portion 23 has a triangular (V-shaped) cross section and has a protrusion 25 that protrudes sharply radially inward on the inner circumferential surface of the main body 11.

[0034] Similar to the first locking portion 23, the second locking portion 24 extends in the circumferential direction and has a serration shape (rib shape) that bends from the outer circumferential surface side to the inner circumferential surface side of the main body portion 11, as shown in Fig. 3. As shown in Fig. 5, the second locking portion 24 has one end 24A as a closed end located closer to the open end 15 of the recess 12 on one end side of the main body portion 11 than one end 23A of the first locking portion 23. As shown in Fig. 4, the one end 24A of the second locking portion 24 is positioned so as to overlap the recessed slope 16 when viewed in the axial direction. As shown in FIG. 5, the second locking portion 24 has a closed end 24B at a position closer to the base end 18 of the convex portion 13 on the other end side of the main body 11 than the other end 23B of the first locking portion 23. As shown in FIG. 4, the other end 24B of the second locking portion 24 is positioned so as to overlap the convex slope 19 when viewed in the axial direction. As shown in FIG. 5, the one end 24A and the other end 24B of the second locking portion 24 are inclined relative to the front-to-rear direction on the inner circumferential surface of the main body 11 so as to be parallel to the concave slope 16 and the convex slope 19, respectively. The second locking portion 24 extends continuously and seamlessly in the circumferential direction from the one end 24A to the other end 24B. As shown in FIG. 3, the second locking portion 24 has a trapezoidal (angled U-shaped) cross section and has a flat surface 26 that is horizontal along the front-to-rear direction on the inner circumferential surface of the main body 11.

[0035] 5, the front-to-rear width of the first locking portion 23 is set to be smaller than the front-to-rear width of the second locking portion 24. Within the front-to-rear width of the main body 11, uniform or nearly uniform spacing spaces 27 that exceed the front-to-rear width of the second locking portion 24 are formed between the first locking portion 23 and the second locking portion 24 and between the front and rear ends of the main body 11 and the second locking portion 24.

[0036] (Action of the shield receiving member and shield connector) When assembling the shielded connector 60, the main body 11 of the shield receiving member 10 is disposed on the outer periphery of the outer sheath 93, as shown in FIG. 4. The main body 11 is bent into a cylindrical shape and disposed so that the protrusion 13 fits inside the recess 12. In the cylindrical main body 11, the bottom 14 of the recess 12 and the tip 17 of the protrusion 13 face each other, and the concave slope 16 and the convex slope 19 are disposed so as to contact each other in an oblique direction intersecting the axial direction. As shown in FIG. 6, one end 23A and the other end 23B of the first locking portion 23 are disposed circumferentially at a distance L1. Furthermore, one end 24A and the other end 24B of the second locking portion 24 are disposed circumferentially at a distance L2. On the other hand, the other end 23B of the first locking portion 23 and one end 24A of the second locking portion 24 are disposed at a distance L3 in the circumferential direction when viewed in the axial direction, which is sufficiently smaller than the distances L1 and L2.

[0037] 4, the front end portion of the shield portion 92 is folded back, and a shield tip portion 97 is disposed on the outer peripheral surface of the main body 11. Furthermore, the crimping portion 36 of the first outer conductor terminal 31 is crimped onto the outer peripheral surface of the shield tip portion 97. As shown in FIG. 3, at the lower end side of the shielded connector 60, the extending portion 34 of the second outer conductor terminal 32 is disposed on the outer peripheral surface of the shield tip portion 97, and each barrel piece 38 of the crimping portion 36 is crimped onto the outer peripheral surface of the extending portion 34.

[0038] 3, the shield tip portion 97 crimped to the crimping portion 36 fits into the recess that opens into the outer peripheral surface of the main body 11 in each of the first locking portion 23 and each of the second locking portions 24. In particular, each second locking portion 24 has a larger opening width than the first locking portion 23, corresponding to the front-to-rear width of the flat surface 26, and therefore the shield tip portion 97 can enter a larger amount. Therefore, even if a rearward pulling force or the like acts on the shield tip portion 97, the shield tip portion 97 is prevented from slipping out from between the crimping portion 36 and the shield receiving member 10.

[0039] Furthermore, the protruding surface 25 of the first locking portion 23 and the flat surface 26 of each second locking portion 24 are arranged to bite into the outer sheath 93 of the electric wire 90. In particular, the protruding shape of the protruding surface 25 of the first locking portion 23 arranged in the center in the front-to-rear direction of the main body 11 allows it to firmly bite into the outer sheath 93. Therefore, even if a pulling force or the like acts on the outer sheath 93 in the rearward direction, the outer sheath 93 (electric wire 90) is prevented from slipping out from inside the main body 11.

[0040] As described above, when viewed from the axial direction with main body 11 bent into a cylindrical shape and protrusion 13 disposed inside recess 12, circumferential distance L3 between other end 23B of first locking portion 23 and one end 24A of second locking portion 24 is made sufficiently smaller than distance L1 between both circumferential ends of first locking portion 23 and distance L2 between both circumferential ends of second locking portion 24 (see FIG. 6). Therefore, the serration shape formed by first locking portion 23 and each second locking portion 24 is discontinuous in the circumferential direction as a whole, but appears to be continuous without any significant breaks.

[0041] Even if a gap occurs between the recess 12, the concave inclined surface 16, and the convex inclined surface 19 of the protruding portion 13, the serration shape is formed almost continuously in the circumferential direction, so that the wire 90 can be reliably prevented from slipping out of the shielded connector 60, thereby improving the wire holding force.

[0042] Furthermore, according to the first embodiment, the second locking portions 24 are arranged in pairs on both the front and rear sides of the first locking portion 23, so that the electric wire 90 can be held firmly and stably.

[0043] Moreover, since each second locking portion 24 has a flat surface 26 along the front-rear direction on its inner circumferential surface, the shield tip portion 97 is stably held by the second locking portion 24. Furthermore, the first locking portion 23 has a sharp protruding surface 25 on its inner circumferential surface, and this protruding surface 25 can bite into the outer sheath 93, so that displacement of the outer sheath 93 (electric wire 90) relative to the shield receiving member 10 is reliably restricted.

[0044] Furthermore, since the front-to-back width of the first locking portion 23 is smaller than the front-to-back width of the second locking portion 24, even if the front-to-back width of the main body portion 11 becomes smaller, sufficient separation space 27 can be secured within the front-to-back width of the main body portion 11.

[0045] Furthermore, since the other end 23B of the first locking portion 23 is positioned to overlap the convex slope 19 when viewed in the axial direction, and one end 24A of the second locking portion 24 is positioned to overlap the concave slope 16 when viewed in the axial direction, the first locking portion 23 and each second locking portion 24 are positioned in a space-efficient manner within the front-to-rear width of the main body 11, which can contribute to the miniaturization of the main body 11. If the main body 11 can be made smaller, the first outer conductor terminal 31 can also be made smaller, which reduces material costs and provides excellent versatility.

[0046] [Another embodiment of the present disclosure] The first embodiment disclosed herein should be considered to be illustrative in all respects and not restrictive. In the first embodiment, one first locking portion is disposed in the center of the front and rear of the main body. In contrast to this, in other embodiments, a plurality of first locking portions may be disposed in the center of the front and rear of the main body. In the first embodiment, a pair of second locking portions is disposed on both the front and rear sides of the first locking portion on the main body. In contrast, in other embodiments, multiple pairs of second locking portions may be disposed on both the front and rear sides of the first locking portion on the main body. In the first embodiment, the convex portions are formed in a triangular convex shape when viewed from the radial direction, and the concave portions are formed in a triangular concave shape when viewed from the radial direction. In contrast, in other embodiments, the convex portions may be formed in a square convex shape or a curved convex shape when viewed from the radial direction, and the concave portions may be formed in a square concave shape or a curved concave shape when viewed from the radial direction. In the first embodiment, the projecting surface of the convex portion is formed in a sharp point shape, whereas in other embodiments, the projecting surface of the convex portion may be formed in a curved shape. In the first embodiment, one recess is disposed at one end of the main body, and one protrusion is disposed at the other end of the main body. In contrast, in other embodiments, multiple recesses may be arranged side by side at one end of the main body, and multiple protrusions may be arranged side by side at the other end of the main body. In the first embodiment, a circumferential distance L3 is formed between the other end of the first locking portion and one end of the second locking portion. In contrast, in other embodiments, the distance L3 is not formed, and the other end side of the first locking portion and the one end side of the second locking portion may be positioned to overlap when viewed from the axial direction.
