DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [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) The outer conductor is cylindrical and is crimped to an end of a cable having a core. The outer conductor is divided into two in the circumferential direction: a first region and a second region. The outer conductor has a fixed contact portion provided in the first region, whose position is fixed with respect to the first region and which contacts the peripheral surface of the mating outer conductor, and an elastic contact portion provided in the second region and which elastically contacts the peripheral surface of the mating outer conductor.

[0010] With this configuration, the elastic contact portion of the second region elastically contacts the circumferential surface of the mating outer conductor, thereby maintaining the fixed contact portion of the first region in contact with the circumferential surface of the mating outer conductor, making it easier to determine the radial positions of the mating outer conductor and the outer conductor.

[0011] (2) The elastic contact parts are partitioned by slits formed in the second region, and multiple elastic contact parts are arranged side by side in the circumferential direction. Adjacent elastic contact parts preferably face a single common slit. With this configuration, adjacent elastic contact parts are partitioned by a single slit, so that the dimension between adjacent elastic contact parts can be easily narrowed, and the area of ​​the slit can be reduced. Therefore, it is easy to reduce the difference in impedance between the part with the slit and the part without the slit in the axial direction of the outer conductor.

[0012] (3) In (2), it is preferable that the outer conductor is inserted into the mating outer conductor and the slit is surrounded by the mating outer conductor. With this configuration, since the slit is surrounded by the mating outer conductor, it is possible to prevent electromagnetic noise from leaking from the slit and improve the shielding performance.

[0013] (4) The dielectric is disposed inside the outer conductor. The radial thickness of the dielectric at a portion facing the inner surface of the first region is preferably greater than the radial thickness of the dielectric at a portion facing the inner surface of the second region. With this configuration, the impedance on the first region side can be reduced to approach the impedance on the second region side, thereby allowing the overall impedance in the radial direction to approach a desired value.

[0014] (5) In (4) which directly or indirectly cites (2), the second region is provided with a connecting slit which separates the end of the elastic contact portion in the axial direction of the core wire from the outer conductor and is connected to the slit, and is provided with an inner conductor into which a mating tab is inserted, and the exposed portion of the tab exposed from the inner conductor is accommodated in the dielectric, and it is preferable that the position of the connecting slit in the axial direction of the core wire is different from the exposed portion of the tab. The position where the slit is formed in the outer conductor and the exposed portion of the tab are portions where impedance tends to be high. Therefore, if these positions are aligned in the axial direction of the core wire, the impedance at that position becomes excessively high. Therefore, according to this configuration, these positions are made different, so that it is possible to prevent the occurrence of portions where the impedance becomes excessively high.

[0015] (6) It is preferable that a deflection space is formed inside the second region into which the elastic contact portion can enter when it is elastically deformed. With this configuration, it is possible to make it difficult for the deflection space to hinder the elastic deformation of the elastic contact portion.

[0016] [Details of the embodiment of the present disclosure] [Embodiment 1] A first embodiment of the technology disclosed in this specification will be described with reference to Figures 1 to 9. In the following description, the right side in Figure 1 is defined as the front, and the left side as the rear. The front is the direction in which the mating connector 60 is located relative to the connector 10.

[0017] [Connector configuration] As shown in Fig. 1, the connector 10 includes a sleeve 11, an inner conductor 13, a dielectric 14, and an outer conductor 15. The connector 10 is attached to an end of a shielded electric wire W. The outer conductor 15 includes a first outer conductor 15A and a second outer conductor 15B. The sleeve 11, the first outer conductor 15A, the inner conductor 13, and the second outer conductor 15B are made of metal. The dielectric 14 is made of synthetic resin. The connector 10 is electrically connected to a mating connector 60 (see Fig. 7).

[0018] The shielded electric wire W, which is a cable, is a so-called coaxial wire. The shielded electric wire W has a conductive core wire 51 formed by twisting together a plurality of elemental wires, an insulating coating 52 surrounding the outer periphery of the core wire 51, a conductive braided wire 53 surrounding the outer periphery of the coating 52 and formed by weaving the elemental wires into a net shape, and an insulating sheath surrounding the outer periphery of the braided wire 53. The core wire 51 has a function of transmitting high-frequency signals. The braided wire 53 has a function of shielding electromagnetic waves. The shielded electric wire W has a form in which the core wire 51 and the braided wire 53 are exposed in this order from the tip side by stripping off the sheath and the coating 52.

[0019] The sleeve 11 is annular. The sleeve 11 is disposed to surround the outer periphery of the braided wire 53, and the outer surface of the sleeve 11 is covered by the folded-back front end of the braided wire 53. The sleeve 11 has a function of receiving a crimping load.

[0020] The inner conductor 13 is formed by bending a metal plate, etc. The inner conductor 13 is configured by connecting a mating connection portion 13A, a cylindrical portion 13B, and a central conductor crimping portion 13C in this order from the front side to the rear side.

[0021] The tubular portion 13B has a cylindrical shape that is elongated in the front-rear direction. The mating connection portion 13A is composed of a pair of elastic pieces 13D that protrude forward from the tubular portion 13B (see FIG. 2). The elastic pieces 13D are arranged opposite each other across the axis of the tubular portion 13B. The tab 64 of the mating inner conductor 61 is inserted into the mating connection portion 13A. When the tab 64 of the mating inner conductor 61 is inserted between the elastic pieces 13D, the elastic pieces 13D open to guide the tab 64 and sandwich the tab 64 from the radial direction (see FIG. 8). The central conductor crimping portion 13C has an open barrel shape and is connected to the rear end of the tubular portion 13B. The exposed core wire 51 of the shielded electric wire W is inserted into the central conductor crimping portion 13C. The central conductor crimping portion 13C is crimped to the core wire 51, whereby the inner conductor 13 and the core wire 51 are connected to each other.

[0022] The dielectric 14 is cylindrical and has an inner conductor insertion hole 14A with a circular cross section that penetrates in the front-rear direction. A thick portion 14B is provided at the front end of the dielectric 14, where the inner diameter of the inner conductor insertion hole 14A is made smaller. The thick portion 14B has a thickness in the radial direction from the axis of the core wire 51 that is greater than other portions of the dielectric 14. The inner conductor 13 is inserted into the inner conductor insertion hole 14A of the dielectric 14 from the rear. The inner conductor 13 is provided with a stopper portion 13E, which abuts against a front end of a stopper receiving portion 14C formed in the inner conductor insertion hole 14A from the rear, so that the inner conductor 13 is stopped at the front with respect to the dielectric 14.

[0023] 1 and 2, the front side in the axial direction of the dielectric 14 is formed so that one side in the circumferential direction is thicker than the other side. The thickness in the radial direction of the front side in the axial direction of the dielectric 14 is formed so as to gradually become thicker from the other side (the lower side in FIG. 2) toward one side (the upper side in FIG. 2) (see FIG. 2).

[0024] The first outer conductor 15A is formed into a cylindrical shape by bending a metal plate or the like. As shown in FIG. 1, the first outer conductor 15A has a first cylindrical portion 15C and a second cylindrical portion 15D located forward of the first cylindrical portion 15C. The first cylindrical portion 15C and the second cylindrical portion 15D are arranged coaxially. The outer diameter of the first cylindrical portion 15C is larger than that of the second cylindrical portion 15D. A reduced diameter portion 15E is formed between the first cylindrical portion 15C and the second cylindrical portion 15D. The outer diameter of the reduced diameter portion 15E is smaller than that of the first cylindrical portion 15C and the second cylindrical portion 15D. The first cylindrical portion 15C surrounds the sleeve 11 covered by the front end of the folded back braided wire 53. The second cylindrical portion 15D is located forward of the first cylindrical portion 15C and at the end of the coating 52 of the shielded electric wire W. The first outer conductor 15A is connected to the shielded electric wire W by being crimped to the sheath of the shielded electric wire W. The rear end of the dielectric 14 is disposed adjacent to the tip of the second tubular portion 15D. The rear end of the dielectric 14 surrounds the core wire 51.

[0025] The second outer conductor 15B is formed into a cylindrical shape by bending a metal plate or the like. The second outer conductor 15B has a third cylindrical portion 15F and a fourth cylindrical portion 15G located forward of the third cylindrical portion 15F. The third cylindrical portion 15F and the fourth cylindrical portion 15G are arranged coaxially. The outer diameter of the third cylindrical portion 15F is larger than the outer diameter of the fourth cylindrical portion 15G. The second cylindrical portion 15D of the first outer conductor 15A is fitted into the third cylindrical portion 15F. The fourth cylindrical portion 15G is located forward of the third cylindrical portion 15F. The fourth cylindrical portion 15G is divided into a first region 15K and a second region 15L (see FIG. 2). The first region 15K is one of the regions obtained by dividing the second outer conductor 15B into two in the circumferential direction (see FIG. 2). The second region 15L is the other region obtained by dividing the second outer conductor 15B into two in the circumferential direction (see FIG. 2). The first region 15K and the second region 15L are each in the shape of a semicircle.

[0026] As shown in Figs. 2, 3, and 4, the fourth cylindrical portion 15G is provided with three fixed contact portions 15H and three elastic contact portions 15J. The three fixed contact portions 15H are provided only in the first region 15K (see Fig. 2). These fixed contact portions 15H extend in the axial direction of the second outer conductor 15B and are formed so as to protrude in radial directions from the axis of the second outer conductor 15B (see Figs. 2 and 3). These fixed contact portions 15H are arranged in the first region 15K at equal intervals in the circumferential direction (see Fig. 2). The positions of these fixed contact portions 15H are fixed with respect to the first region 15K. In other words, the fixed contact portions 15H do not displace relative to the second outer conductor 15B.

[0027] The three elastic contact portions 15J are provided in the second region 15L (see FIG. 2). That is, the fourth cylindrical portion 15G of the second outer conductor 15B is divided in the circumferential direction into one first region 15K and one second region 15L. These elastic contact portions 15J are partitioned by slits 15M formed in the second region 15L and are arranged side by side in the circumferential direction of the second outer conductor 15B.

[0028] The slit 15M is formed by four partition slits 15N extending in the axial direction of the second outer conductor 15B and a connecting slit 15P extending in the circumferential direction and connecting the front ends of the partition slits 15N (see FIG. 4). The connecting slit 15P is formed in the second region 15L. The connecting slit 15P is continuous with each partition slit 15N (see FIG. 4). The connecting slit 15P separates the front end of the elastic contact portion 15J in the axial direction of the core wire 51 from the fourth cylindrical portion 15G of the second outer conductor 15B (see FIG. 4). The position of the connecting slit 15P in the axial direction of the core wire 51 is different from the position of the thick portion 14B of the dielectric 14 (see FIG. 1).

[0029] The three elastic contact portions 15J are disposed between adjacent partition slits 15N, and are elastically deformable in the radial direction with the rear end as a fulcrum. Each elastic contact portion 15J is formed so as to gradually widen outward (away from the axis of the fourth cylindrical portion 15G) from the rear end to the front end, and the front end is bent inward (toward the axis of the fourth cylindrical portion 15G). Each elastic contact portion 15J is formed in a mountain shape that protrudes outward. In the fourth cylindrical portion 15G, the front end of each elastic contact portion 15J is located closer to the third cylindrical portion 15F (rearward) than the front end of the fixed contact portion 15H (see FIG. 1). At the top of the mountain shape of each elastic contact portion 15J, a bead 15Q is formed that protrudes outward in a rounded manner. In the fourth cylindrical portion 15G, each bead 15Q is located closer to the third cylindrical portion 15F (rearward) than the front end of the elastic contact portion 15J, and is located closer to the third cylindrical portion 15F (rearward) than the front end of the fixed contact portion 15H (see FIG. 1). The elastic contact portions 15J adjacent in the circumferential direction face a common partition slit 15N (see FIG. 4).

[0030] As shown in FIG. 2, the three fixed contact portions 15H and the three beads 15Q are arranged at equal intervals in the circumferential direction. One fixed contact portion 15H and one bead 15Q are arranged on the opposite side across the axis of the fourth tubular portion 15G of the second outer conductor 15B. When the second outer conductor 15B is inserted into the mating outer conductor 65, the three fixed contact portions 15H come into contact with the inner surface, which is the circumferential surface, of the mating outer conductor 65. At the same time, the three beads 15Q come into elastic contact with the inner surface, which is the circumferential surface of the mating outer conductor 65 (see FIG. 8). As a result, the three fixed contact portions 15H and the three beads 15Q of the second outer conductor 15B can be reliably contacted with the mating outer conductor 65 by maintaining a constant positional relationship (i.e., a coaxial positional relationship) in the radial direction.

[0031] The dielectric 14 is inserted into the second outer conductor 15B from the rear. That is, the dielectric 14 is disposed inside the second outer conductor 15B. As shown in Fig. 5, the third cylindrical portion 15F of the second outer conductor 15B is provided with a protruding portion 15R that protrudes inward. This protruding portion 15R abuts against the rear end of the recessed portion 14D formed on the outer surface of the dielectric 14 from the front, so that the dielectric 14 is stopped at the front with respect to the second outer conductor 15B.

[0032] As shown in Fig. 2, at the front side in the axial direction of the dielectric 14, one side portion 14E formed to be thick in the radial direction is disposed adjacent to the inner surface of the first region 15K of the second outer conductor 15B. At the front side in the axial direction of the dielectric 14, the other side portion 14F formed to be thin in the radial direction is disposed adjacent to the inner surface of the second region 15L of the second outer conductor 15B. That is, the dielectric 14 is disposed inside the first region 15K and the second region 15L. The radial thickness of the portion of the dielectric 14 facing the inner surface of the first region 15K is thicker than the radial thickness of the portion of the dielectric 14 facing the inner surface of the second region 15L.

[0033] The gap between the inner surface of the second region 15L and the outer surface of the dielectric 14 located on this inner surface is wider than the gap between the inner surface of the first region 15K and the outer surface of the dielectric 14 located on this inner surface. A deflection space R into which the elastic contact portion 15J elastically deformed inward can enter is formed between the inner surface of the second region 15L and the outer surface of the dielectric 14 located on this inner surface. In other words, the deflection space R is formed inside the second region 15L.

[0034] The second cylindrical portion 15D of the first outer conductor 15A is fitted into the third cylindrical portion 15F of the second outer conductor 15B, and the outer surface of the second cylindrical portion 15D is in contact with the inner surface of the third cylindrical portion 15F (see FIG. 1). The second cylindrical portion 15D of the first outer conductor 15A and the third cylindrical portion 15F of the second outer conductor 15B are connected by, for example, spot welding.

[0035] [Configuration of the mating connector] 6, the mating connector 60 includes a sleeve 66, a mating inner conductor 61, a first outer conductor 63, a mating outer conductor 65, and a mating dielectric 62. The mating connector 60 is attached to an end of a shielded electric wire W that is different from the shielded electric wire W to which the connector 10 is attached. The sleeve 66 has a similar structure to the sleeve 11. The first outer conductor 63 has a similar structure to the first outer conductor 15A.

[0036] The mating inner conductor 61 is made of metal. The mating inner conductor 61 is connected to the core wire 51 of the shielded electric wire W by crimping, and has a tab 64 protruding forward. The mating outer conductor 65 is made of metal and has a cylindrical shape. The second tube portion 15D of the first outer conductor 63 is fitted into the base end portion of the mating outer conductor 65. The mating outer conductor 65 and the first outer conductor 63 are connected by, for example, spot welding. The mating outer conductor 65 surrounds the entire mating inner conductor 61.

[0037] The mating dielectric 62 is made of synthetic resin. The mating dielectric 62 is disposed between the mating inner conductor 61 and the mating outer conductor 65. The mating dielectric 62 surrounds the mating inner conductor 61 except for its tip portion (tab 64).

[0038] [About connecting with the other connector] The operation of the connector 10 when connecting the connector 10 to the mating connector 60 will be described. Specifically, the tip of the fourth cylindrical portion 15G of the second outer conductor 15B of the connector 10 is brought into opposition to the tip of the mating outer conductor 65 of the mating connector 60. At the same time, the mating outer conductor 65 and the second outer conductor 15B are butted together so as to be coaxial.

[0039] Then, the fourth cylindrical portion 15G of the second outer conductor 15B is inserted into the mating outer conductor 65. Then, first, the three fixed contact portions 15H come into contact with the inner surface of the mating outer conductor 65. Next, the front ends of the three elastic contact portions 15J come into contact with the inner surface of the mating outer conductor 65.

[0040] Furthermore, when the insertion of the fourth cylindrical portion 15G of the second outer conductor 15B into the mating outer conductor 65 is continued, the three elastic contact portions 15J are elastically deformed by being pressed inward by the mating outer conductor 65. At this time, the three elastic contact portions 15J enter the deflection space R formed between the dielectric 14 and the second outer conductor 15B while being in elastic contact with the inner surface of the mating outer conductor 65 (see FIG. 7).

[0041] Next, the beads 15Q provided on each of the three elastic contact portions 15J come into contact with the inner surface of the mating outer conductor 65. In this way, the three fixed contact portions 15H and the beads 15Q provided on each of the three elastic contact portions 15J come into contact with the inner surface of the mating outer conductor 65 (see FIG. 8).

[0042] At the same time, the tab 64 of the mating inner conductor 61 is inserted into the mating connecting portion 13A of the inner conductor 13. When the fourth tubular portion 15G of the second outer conductor 15B is further inserted into the mating outer conductor 65, the front end of the dielectric 14 comes into surface contact with the tip of the mating dielectric 62 (see FIG. 7). In this way, the connecting operation for electrically connecting the connector 10 and the mating connector 60 is completed. As a result, the two shielded electric wires W are electrically connected via the inner conductor 13 and the mating inner conductor 61, and a signal conductive path is formed between the connector 10 and the mating connector 60. The thick portion 14B of the dielectric 14 accommodates an exposed portion 64A of the tab 64 that is exposed from the inner conductor 13 (see FIG. 7). The exposed portion 64A of the tab 64 is located at a different position from the connecting slit 15P in the axial direction of the core wire (see FIG. 7).

[0043] The three fixed contact portions 15H come into contact with the inner surface of the mating outer conductor 65, so that the mating outer conductor 65 and the fourth tubular portion 15G of the second outer conductor 15B are positioned coaxially (see FIG. 8). The three elastic contact portions 15J come into elastic contact with the inner surface of the mating outer conductor 65, so that the three fixed contact portions 15H can be maintained in contact with the inner surface of the mating outer conductor 65 (see FIG. 8). In other words, the three elastic contact portions 15J and the three fixed contact portions 15H maintain the mating outer conductor 65 and the fourth tubular portion 15G of the second outer conductor 15B in a coaxial arrangement state.

[0044] 9, the second outer conductor 15B is adapted to be inserted into the mating outer conductor 65. When viewed from a direction perpendicular to the axis of the second outer conductor 15B in a state in which the second outer conductor 15B is inserted into the mating outer conductor 65, the slit 15M formed in the fourth cylindrical portion 15G of the second outer conductor 15B is surrounded by the mating outer conductor 65. This prevents electromagnetic noise from being emitted to the outside via the slit 15M.

[0045] Next, the effects of the first embodiment will be described.

[0046] The connector 10 of the present disclosure includes a cylindrical outer conductor 15 that is crimped to an end of a shielded electric wire W having a core wire 51. The outer conductor 15 is divided into two parts, a first region 15K and a second region 15L, in the circumferential direction. The outer conductor 15 has a fixed contact portion 15H and a resilient contact portion 15J. The fixed contact portion 15H is provided in the first region 15K, is fixed in position relative to the first region 15K, and contacts the inner surface of the mating outer conductor 65. The resilient contact portion 15J is provided in the second region 15L and resiliently contacts the inner surface of the mating outer conductor 65. According to this configuration, the elastic contact portion 15J of the second region 15L elastically contacts the inner surface of the mating outer conductor 65, thereby maintaining the fixed contact portion 15H of the first region 15K in contact with the inner surface of the mating outer conductor 65, making it easier to determine the radial positions of the mating outer conductor 65 and the outer conductor 15.

[0047] The elastic contact portion 15J of the connector 10 of the present disclosure is partitioned by slits 15M formed in the second region 15L, and multiple elastic contact portions 15J are arranged side by side in the circumferential direction. Adjacent elastic contact portions 15J face a common partition slit 15N. With this configuration, adjacent elastic contact portions 15J are partitioned by a single partition slit 15N, so that the dimension between adjacent elastic contact portions 15J can be easily narrowed, and the area of ​​the slit 15M can be reduced. Therefore, in the axial direction of the outer conductor 15, it is easy to keep the impedance difference small between the portion where the slit 15M is formed and the portion where the slit 15M is not formed.

[0048] In the connector 10 of the present disclosure, the outer conductor 15 is inserted into the mating outer conductor 65, and the slit 15M is surrounded by the mating outer conductor 65. According to this configuration, since the slit 15M is surrounded by the mating outer conductor 65, it is possible to prevent electromagnetic noise from leaking from the slit 15M, and improve the shielding performance.

[0049] The connector 10 of the present disclosure includes a dielectric 14 disposed inside an outer conductor 15. The radial thickness of the dielectric 14 at a portion facing the inner surface of the first region 15K is greater than the radial thickness of the dielectric 14 at a portion facing the inner surface of the second region 15L. With this configuration, the impedance on the first region 15K side can be reduced to approach the impedance on the second region 15L side, thereby allowing the overall impedance in the radial direction to approach a desired value.

[0050] In the second region 15L of the connector 10 of the present disclosure, a connecting slit 15P is formed which separates the end of the elastic contact portion 15J in the axial direction of the core wire 51 from the outer conductor 15 and is connected to the partition slit 15N. The connector 10 includes an inner conductor 13 into which a mating tab 64 is inserted, and an exposed portion 64A of the tab 64 exposed from the inner conductor 13 is accommodated in the dielectric 14, and the position of the connecting slit 15P in the axial direction of the core wire 51 is different from the exposed portion 64A of the tab 64. The position where the connecting slit 15P is formed in the outer conductor 15 and the exposed portion 64A of the tab 64 are portions where impedance tends to be high. For this reason, if these positions are aligned in the axial direction of the core wire 51, the impedance at that position becomes excessively large. Therefore, according to this configuration, these positions are made different, so that it is possible to prevent the occurrence of a portion where the impedance becomes excessively large.

[0051] In the connector 10 of the present disclosure, a deflection space R into which the elastic contact portion 15J can enter when it is elastically deformed is formed inside the second region 15L. With this configuration, the deflection space R can make it difficult to prevent the elastic deformation of the elastic contact portion 15J.

[0052] [Other embodiments] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is not limited to the embodiments disclosed herein, but is indicated by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0053] Unlike the first embodiment, the number of each of the fixed contact portions and the elastic contact portions may be four or more. The number of each of the fixed contact portions and the elastic contact portions may be different. Also, a configuration may be provided in which a plurality of fixed contact portions and one elastic contact portion are provided.

[0054] Unlike the first embodiment, a configuration may be adopted in which no connecting slits are formed. In this case, the elastic contact portions are defined only by the defining slits.

[0055] Unlike the first embodiment, a connecting slit may be disposed so as to connect the rear ends of the partitioning slits to each other.

[0056] Unlike the first embodiment, the fixed contact portion and the elastic contact portion may be formed to protrude inward and come into contact with the outer surface, which is the circumferential surface, of the mating outer conductor. [Explanation of symbols]
