Description

[Technical field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] Patent Document 1 discloses a connector including a shielded electric wire, an inner conductor called a first contact means, an outer conductor called a second contact means, and a sleeve called a ferrule. The inner conductor is connected to the inner conductor of the shielded electric wire. The outer conductor is connected to a shielding member such as a braided wire that is the outer conductor of the shielded electric wire. The sleeve is disposed on the inner periphery side of the outer conductor and on the outer periphery side of the shielded electric wire. The shielding member is folded back on the sleeve via a folded back portion and disposed from the inner periphery side to the outer periphery side of the sleeve. When the outer conductor is compressed toward the center (inner periphery side) in the radial direction by a crimping tool, the shielding member is sandwiched and held between the outer conductor and the sleeve.

[0003] Patent Document 2 discloses a connector in which a member equivalent to a sleeve is disposed on the inner periphery of a shielding member, and a recess is formed in the member. When the outer conductor is compressed to the inner periphery, the shielding member enters the recess and is locked in place. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-168440 A [Patent Document 2] JP 2008-66149 A Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, for example, when the shielded electric wire is pulled in the direction of removal, the folded-back portion of the shielding member may strongly interfere with the sleeve, causing the shielding member to be damaged. In response to this, it is possible to apply the technology of Patent Document 2 and provide a protruding portion (a portion corresponding to the "recess" in Patent Document 2) on the inner periphery of the sleeve. By compressing the inner periphery of the shielding member with the protruding portion of the sleeve, the inner periphery of the shielding member is sandwiched and held between the sleeve and the insulating coating, and it is expected that the positional deviation in the direction of removal of the shielding member is restricted. However, there is a concern that the insulating coating may be significantly deformed toward the center in the radial direction due to the protruding portion of the sleeve, causing the coaxial structure of the shielded electric wire to collapse. If the coaxial structure collapses, it may cause impedance mismatching and deteriorate the signal transmission quality.

[0006] In view of the above, an object of the present disclosure is to provide a connector that is capable of regulating positional deviation of a shielding member while ensuring transmission quality. [Means for solving the problem]

[0007] The present disclosure relates to a connector comprising: a shielded wire in which an outer periphery of an insulating coating that covers a central conductor is surrounded by a shielding member; an outer conductor connected to the shielding member; an inner conductor connected to the center conductor; a tubular sleeve arranged on the outer periphery of the insulating coating and on the inner periphery of the outer conductor; and an inner shield portion provided on the shielding member and arranged between the sleeve and the insulating coating, wherein the sleeve has a convex portion that extends in a circumferential direction and protrudes toward the inner periphery, the inner shield portion has a concave portion on its outer periphery surface on the outer periphery side that corresponds to the convex portion, and a corresponding portion of the inner shield portion that corresponds to the concave portion on the inner periphery surface on the inner periphery side is configured to protrude toward the inner periphery by an amount smaller than the depth of the concave portion, or to have a zero amount of protrusion. Effect of the Invention

[0010] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) A shielded electric wire comprising an insulating coating that covers a central conductor and is surrounded by a shielding member, an outer conductor connected to the shielding member, an inner conductor connected to the central conductor, a cylindrical sleeve arranged on the outer peripheral side of the insulating coating and on the inner peripheral side of the outer conductor, and an inner shield part provided on the shielding member and arranged between the sleeve and the insulating coating, wherein the sleeve has a convex part that extends in a circumferential direction and protrudes toward the inner peripheral side, and the inner shield part has a concave part on its outer peripheral surface on the outer peripheral side that corresponds to the convex part, and a corresponding portion of the inner shield part that corresponds to the concave part on the inner peripheral surface on the inner peripheral side protrudes toward the inner peripheral side by an amount of protrusion that is smaller than the depth of the concave part, or the amount of protrusion is zero.

[0011] The concave portion of the inner shield portion receives the convex portion of the sleeve, thereby preventing the inner shield portion from being misaligned with respect to the sleeve. The corresponding portion of the inner surface of the inner shield portion does not protrude toward the inner circumference, or if it does protrude, it is kept small. This prevents the insulating coating from being strongly compressed by the inner shield portion, and the coaxial structure of the shielded wire can be maintained. As a result, impedance fluctuations can be suppressed, and signal transmission quality can be ensured.

[0012] (2) In the connector described in (1) above, it is preferable that the shielding member is folded over from the inner side to the outer side of the sleeve, has the inner shielding portion on the inner side of the sleeve, and has an outer shielding portion on the outer side of the sleeve that is positioned between the outer conductor and the sleeve. A folded-back portion of the shielding material is provided between the inner and outer shielding portions. In this configuration, the concave portion receives the convex portion, thereby preventing the inner shielding portion from shifting out of position. Therefore, even if a pulling force is applied to the shielded electric wire in the direction of removal, the folded-back portion can be prevented from strongly interfering with the sleeve.

[0013] (3) In the connector described in (1) or (2) above, it is preferable that the sleeve has mating portions at both ends in the circumferential direction that fit in an uneven manner, and the convex portions are positioned in a position that does not overlap with the mating portions in the circumferential direction of the sleeve. When the mating portion is subjected to the compressive force of the outer conductor and fits together in an uneven manner, the convex portion is positioned so that it does not overlap with the mating portion in the circumferential direction. This prevents the insulating coating from being compressed by both the mating portion and the convex portion, and properly maintains the coaxial structure of the shielded wire.

[0014] (4) In the connector according to any one of (1) to (3) above, it is preferable that a cross section of the protrusion taken in a direction perpendicular to the circumferential direction has a curved shape. The concave portion of the inner shield portion receives the curved portion of the convex portion, thereby effectively preventing the inner shield portion from being strongly compressed toward the inner circumference.

[0015] (5) In the connector described in any one of (1) to (4) above, it is preferable that the shielding member has a braided wire including the inner shielding portion and a metal foil covering the outer periphery of the insulating coating on the inner side of the inner shielding portion. The metal foil reduces the compressive force transmitted from the inner shield portion to the insulating coating, thereby more properly maintaining the coaxial structure of the shielded wire.

[0016] [Details of the embodiment of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. Note that 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.

[0017] <Embodiment 1> As shown in FIG. 1, the connector 10 according to the first embodiment of the present disclosure includes an inner conductor 20, an outer conductor 30, a sleeve 60, a dielectric 80, and a shielded electric wire 90. The inner conductor 20, the outer conductor 30, and the sleeve 60 are all conductive and are formed, for example, by pressing a metal plate. The dielectric 80 is made of an insulating material such as a synthetic resin. In the following description, the left side of FIG. 1, which is the tip side of the shielded electric wire 90, is the front side in the front-rear direction. In FIG. 1, the front side is represented by an arrow F. In this specification, the axial direction corresponds to the front-rear direction and corresponds to the length direction of the shielded electric wire 90. The radial direction corresponds to the radial direction of the shielded electric wire 90 and means a direction perpendicular to the axial direction. The inner peripheral surface of each member is a surface facing the center side in the radial direction, and the outer peripheral surface of each member is a surface facing the outside in the radial direction.

[0018] (Shielded wire) As shown in FIG. 1 and FIG. 2, the shielded electric wire 90 is configured by arranging a central conductor 91, an insulating coating 92, a shielding member 93, and a sheath 94 in this order from the center side in the radial direction. The shielded electric wire 90 has a coaxial structure with the central conductor 91 at the center. The central conductor 91 is conductive and is configured by, for example, a core wire made of a plurality of twisted wires. The central conductor 91 is a conductor that transmits signals such as high-frequency signals. The insulating coating 92 is an insulating coating that covers the outer periphery of the central conductor 91. The shielding member 93 is a conductor that constitutes the shielding layer of the shielded electric wire 90 and has a role of shielding electromagnetic waves. In the case of the present embodiment 1, the shielding member 93 is configured by having a metal foil 93A and a braided wire 93B. The metal foil 93A is a conductor made of copper foil, aluminum foil, or the like wound around the outer periphery of the insulating coating 92. The braided wire 93B is a conductor in which metal wires such as copper wires and aluminum wires are braided into a net shape. The sheath 94 is an insulating coating that covers the outer periphery of the shield member 93 .

[0019] At the front end of the shielded electric wire 90, the insulating coating 92 and the sheath 94 are removed by stripping. At the front end of the shielded electric wire 90, the central conductor 91 and the shielding member 93 are exposed in stages from the tip side.

[0020] 1, the braided wire 93B is folded back with the sleeve 60 sandwiched therebetween. The braided wire 93B is configured to have an outer circumferential shield part 95 arranged so as to cover the outer circumferential side of the sleeve 60 at the front end part of the shielded electric wire 90, an inner circumferential shield part 96 arranged on the inner circumferential side of the sleeve 60, and a folded back part 97 connecting the inner circumferential shield part 96 and the outer circumferential shield part 95.

[0021] The outer shield part 95 is sandwiched between the outer conductor 30 and the sleeve 60 in the radial direction. The outer peripheral surface of the outer shield part 95 contacts the inner peripheral surface of a body part 34 (described later) of the outer conductor 30, and the inner peripheral surface of the outer shield part 95 contacts the outer peripheral surface of the sleeve 60. The inner shield part 96 is sandwiched between the sleeve 60 and the insulating coating 92 (metal foil 93A) in the radial direction. The outer peripheral surface of the inner shield part 96 contacts the inner peripheral surface of the sleeve 60, and the inner peripheral surface of the inner shield part 96 contacts the outer peripheral surface of the metal foil 93A. The folded part 97 is disposed in contact with or adjacent to the front end face of the sleeve 60.

[0022] (inner conductor, dielectric and outer conductor) 1 and 2, the inner conductor 20 is formed so as to be elongated and extend in the front-rear direction. A pair of mating connection parts 21 that are elastically deformable in the radial direction are provided at the front end of the inner conductor 20. Each mating connection part 21 is connected to a mating terminal fitting (not shown). An open barrel-shaped conductor crimping part 22 is provided at the rear end of the inner conductor 20. A central conductor 91 exposed by stripping an insulating coating 92 is crimped and connected to the conductor crimping part 22. 1, the dielectric body 80 has an accommodating hole 81 penetrating therethrough in the front-rear direction. The inner conductor 20 is inserted into the accommodating hole 81 of the dielectric body 80 from the rear and accommodated therein.

[0023] The outer conductor 30 is configured to have a front member 30A and a rear member 30B. The front member 30A is a cylindrical conductor that surrounds the outer periphery of the dielectric 80. The rear member 30B is a cylindrical conductor that surrounds the outer periphery of the outer shield part 95 of the shielded electric wire 90. The front member 30A and the rear member 30B are both formed into a cylindrical shape by bending a flat metal plate. The front end of the rear member 30B is fitted inside the rear end of the front member 30A. The front end of the rear member 30B and the rear end of the front member 30A are connected by a joining means such as welding.

[0024] The front end of the rear member 30B is provided with a tapered portion 31 tapered over the entire circumference toward the center in the radial direction. The rear end of the rear member 30B is provided with a recess 32 tapered partially toward the center in the radial direction. In addition, the rear end of the rear member 30B is provided with a locking portion 33 that fits into the recess 32 to maintain the cylindrical shape of the rear member 30B.

[0025] A trunk portion 34 having a diameter larger than the constricted portion 31 and the recess 32 is provided at the intermediate portion in the front-rear direction of the rear member 30B. The trunk portion 34 extends with the same diameter in the front-rear direction. The inner peripheral surface of the trunk portion 34 has a circular cross section and contacts the outer peripheral shield portion 95 so as to be conductive. The trunk portion 34 functions as a compression portion that compresses the outer peripheral shield portion 95 toward the center in the radial direction. A fixing portion 35 having a diameter larger than the recess 32 is provided at the rearmost end portion of the rear member 30B. The fixing portion 35 is fixed to the outer peripheral surface of the sheath 94 by being crimped.

[0026] (sleeve) The sleeve 60 is formed into a cylindrical shape by bending a band-shaped metal plate. As shown in Fig. 1, the sleeve 60 is disposed on the inner peripheral side of the body portion 34 of the outer conductor 30. The drawn portion 31 is disposed in front of the sleeve 60. The recess 32 and the locking portion 33 are disposed in the rear of the sleeve 60. The sleeve 60 is a member that receives a compressive force acting from the outer conductor 30 toward the center in the radial direction. The outer peripheral shield portion 95 is sandwiched between the body portion 34 of the outer conductor 30 and the sleeve 60, and maintains a connected state with the outer conductor 30.

[0027] 3 and 4, the sleeve 60 has a constant width in the width direction (front-rear direction). At both ends in the circumferential direction of the sleeve 60, mating portions 61, 62 are provided. The mating portions 61, 62 are constituted by a first mating portion 61 formed at one end of the circumferential ends of the sleeve 60 and a second mating portion 62 formed at the other end.

[0028] The first mating portion 61 is recessed in the center of the width direction of one end, and has a depth in the circumferential direction of the sleeve 60. Specifically, the first mating portion 61 has a bottom surface 63 along the width direction, and has a trapezoidal cross-sectional shape whose width dimension gradually decreases toward the bottom surface 63.

[0029] The second mating portion 62 protrudes from the center in the width direction of the other end. The second mating portion 62 has a top surface 64 along the width direction, and has a trapezoidal cross-sectional shape whose width dimension gradually decreases toward the top surface 64. In short, the second mating portion 62 has a shape that fits with the first mating portion 61. As shown in FIG. 3, when the sleeve 60 is molded into a cylindrical shape, the second mating portion 62 fits into the first mating portion 61. The concave-convex fit of the mating portions 61, 62 restricts the sleeve 60 from being misaligned in the axial direction.

[0030] The sleeve 60 has a plurality of protrusions 65 protruding toward the inner periphery (the radially inner side). Each protrusion 65 is formed by pressing the outer periphery of the sleeve 60 by press working. The outer periphery of the sleeve 60 has recesses 66 formed together with each protrusion 65 at positions corresponding to each protrusion 65.

[0031] Each of the protrusions 65 is formed in a rib shape extending in the circumferential direction on the inner peripheral surface of the sleeve 60. In the case of the first embodiment, each of the protrusions 65 is arranged in parallel with two protrusions 65 spaced apart in the width direction on the inner peripheral surface of the sleeve 60. As shown in FIG. 4, the interval S1 between the front end of the sleeve 60 and the front protrusion 65, the interval S2 between the rear end of the sleeve 60 and the rear protrusion 65, and the interval S3 between the protrusions 65 are set to be the same. However, the interval S3 may be set to be different from each of the intervals S1 and S2. Moreover, the intervals S1, S2, and S3 may all be set to be different from each other.

[0032] One circumferential end of each protrusion 65 is adjacent to the bottom surface 63 of the first mating portion 61, and is disposed away in the other circumferential direction from the first mating portion 61. The other circumferential end of each protrusion 65 is adjacent to a base portion 69 of the second mating portion 62, and is disposed away in the other circumferential direction from the second mating portion 62. In short, each protrusion 65 is disposed at a position that does not overlap with the mating portions 61, 62 in the circumferential direction.

[0033] 1, each of the protrusions 65 has a cross section cut along the width direction of the sleeve 60, i.e., a side cross section, which is a curved surface that curves downward. In the case of the first embodiment, the side cross section of each of the protrusions 65 has an arc shape such as a semicircle.

[0034] Since the inner shield part 96 is in close contact with the inner peripheral side of the sleeve 60, a plurality of recesses 98 are formed on the outer peripheral surface of the inner shield part 96 at positions corresponding to the respective protrusions 65. In other words, each recess 98 is a portion that is pressed and compressed by each protrusion 65. Each recess 98 is formed on the outer peripheral surface of the outer shield part 95 at positions spaced apart in the front-to-rear direction so as to extend in the circumferential direction.

[0035] Each recess 98 has a concave shape that can fit with each protrusion 65, and extends in the circumferential direction to a depth corresponding to the protrusion amount of each protrusion 65. The depth of each recess 98 is smaller than the radial distance between the inner circumferential surface of the sleeve 60 and the outer circumferential surface of the insulating member, and is kept within the thickness range of the inner circumferential shield part 96. Corresponding portions 99 (portions on the opposite side of the inner circumferential shield part 96 in the thickness direction from each recess 98) corresponding to each recess 98 on the inner circumferential surface of the inner circumferential shield part 96 do not deform even when pressed by each protrusion 65, and maintain a shape that continues with the same diameter in the front-rear direction.

[0036] (Connector Function) Next, an example of a procedure for assembling the connector 10 will be described. First, the sheath 94 is stripped from the front end of the shielded electric wire 90, and then the insulating coating 92 is stripped. A cylindrical sleeve 60 is inserted into the outer periphery of the braided wire 93B of the shielding member 93 that is exposed by removing the sheath 94. Next, as shown in Fig. 2, the braided wire 93B is folded back, and a folded back portion 97, an inner shield portion 96, and an outer shield portion 95 are formed via the sleeve 60.

[0037] Next, the inner conductor 20 is inserted and housed in the dielectric 80. Furthermore, the dielectric 80 is inserted and housed in the front member 30A of the outer conductor 30. At this time, the rear member 30B of the outer conductor 30 has an open seam along the axial direction. An outer peripheral shield part 95 is disposed inside the rear member 30B.

[0038] Next, a crimping jig (not shown) is applied to the rear member 30B. The rear member 30B is compressed and deformed toward the center in the radial direction by the crimping jig. The outer peripheral shield part 95 is sandwiched and fixed between the rear member 30B and the sleeve 60. A part of the outer peripheral shield part 95 receives the compressive force of the outer conductor 30 and enters each recessed part 66 of the sleeve 60, and the axial positional deviation with respect to the sleeve 60 is restricted.

[0039] The projections 65 of the sleeve 60 bite into the outer peripheral surface of the inner shield part 96 by the compressive force of the outer conductor 30, forming embossed recesses 98. The inner shield part 96 is sandwiched and fixed between the sleeve 60 and the insulating coating 92 (metal foil 93A) by the locking action of the projections 65 and the recesses 98. In this manner, the shield member 93 is connected to the outer conductor 30, and the connector 10 is assembled.

[0040] For example, when the connector 10 is mounted on a vehicle (not shown) or after the connector 10 is mounted on the vehicle, if an external force acts to pull the shielded wire 90 rearward, a rearward displacement force is applied to the inner shield part 96. If the inner shield part 96 is displaced rearward, the folded-back part 97 may interfere with the front end of the sleeve 60, causing the braided wire 93B to be damaged. However, in the case of the first embodiment, as described above, the inner shield part 96 is engaged with each of the protrusions 65 and fixed to the sleeve 60. Therefore, displacement of the inner shield part 96 with respect to the sleeve 60 is restricted, and the folded-back part 97 may not interfere with the front end of the sleeve 60.

[0041] In the first embodiment, the depth of each recess 98 is kept small in correspondence with the protrusion of each protrusion 65. Therefore, the inner surface of the inner shield part 96 is not easily affected by the compressive force of the outer conductor 30, and can maintain a circular shape (perfect circular shape) concentric with the central conductor 91 over the entire circumference. In other words, the corresponding portions 99 corresponding to each recess 98 on the inner surface of the inner shield part 96 have zero protrusion toward the inner circumference. Therefore, it is possible to prevent the outer surface of the insulating coating 92 from being pressed against the corresponding portions 99 and being recessed, and the coaxial structure of the shielded electric wire 90 can be maintained.

[0042] As described above, according to the first embodiment, the recesses 98 of the inner circumferential shield part 96 receive the protrusions 65 of the sleeve 60, thereby restricting misalignment of the inner circumferential shield part 96 with respect to the sleeve 60. Therefore, even if a pulling force is applied to the shielded electric wire 90 in the removal direction, it is possible to prevent the folded-back part 97 from strongly interfering with the sleeve 60. On the other hand, the corresponding portion 99 on the inner surface of the inner shield part 96 does not have a portion that protrudes toward the inner circumference side, and is configured not to strongly compress the insulating coating 92. This makes it possible to maintain the coaxial structure of the shielded electric wire 90. As a result, it is possible to suppress the fluctuation of impedance, and to ensure the transmission quality of signals such as high-frequency signals.

[0043] In addition, when the mating portions 61, 62 are subjected to the compressive force of the outer conductor 30 and engage in an uneven manner, the respective convex portions 65 are positioned so as not to overlap with the mating portions 61, 62 in the circumferential direction. This prevents the insulating coating 92 from being compressed by both the mating portions 61, 62 and the respective convex portions 65, and more properly maintains the coaxial structure of the shielded wire 90.

[0044] Furthermore, since the side cross section of each convex portion 65 has a curved shape, each concave portion 98 can receive the curved portion of each convex portion 65, effectively preventing the inner shield portion 96 from being strongly compressed toward the inner circumference.

[0045] Furthermore, in the case of the first embodiment, the shielding member 93 is configured to include a braided wire 93B including an inner shield portion 96, and a metal foil 93A covering the outer periphery of the insulating coating 92 on the inner periphery side of the inner shield portion 96. With this, the metal foil 93A relieves the compressive force transmitted from the inner shield portion 96 to the insulating coating 92, so that the coaxial structure of the shielded wire 90 can be maintained more appropriately.

[0046] [Another embodiment of the present disclosure] The above-described first embodiment disclosed herein should be considered as illustrative in all respects and not restrictive. In the case of the above-mentioned embodiment 1, the corresponding portion 99 on the inner peripheral surface of the inner peripheral shield part 96 was set so that the amount of protrusion toward the inner peripheral side was zero. In contrast, according to another embodiment, as shown in Fig. 5, the corresponding portion 99A on the inner peripheral surface of the inner peripheral shield part 96 may be pressed by the convex portion 65 and protrude toward the inner peripheral side with an amount of protrusion that is smaller than the depth of the concave portion 98.

[0047] In the case of the above-mentioned embodiment 1, the shielding member 93 has the metal foil 93A, and the metal foil 93A is disposed so as to surround the outer periphery of the insulating coating 92 of the shielded electric wire 90. In contrast, according to other embodiments, the shielding member may not have the metal foil, and the inner peripheral shield portion may be in direct contact with the outer periphery surface of the insulating coating. In the case of the above-mentioned embodiment 1, two protrusions 65 are formed at intervals in the front-rear direction on the inner circumferential surface of the sleeve 60. In contrast to this, according to other embodiments, only one protrusion may be formed on the inner circumferential surface of the sleeve, or three or more protrusions may be formed at intervals in the front-rear direction on the inner circumferential surface of the sleeve. In the case of the above-mentioned embodiment 1, both circumferential ends of the protrusion 65 are disposed apart with the mating portions 61, 62 therebetween. In contrast, according to another embodiment, the protrusion may be formed continuously around the entire circumference of the inner peripheral surface of the sleeve. It is preferable that the recesses are formed on the outer peripheral surface of the inner peripheral shield part in a number and shape corresponding to the protrusions. [Explanation of symbols]
