[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) The connector comprises a first outer conductor, a second outer conductor, and an overlapping portion. The first outer conductor is cylindrical and is crimped to the front end of the cable. The second outer conductor is cylindrical and is fitted coaxially around the front end of the first outer conductor, extending forward of the first outer conductor. The overlapping portion is a portion formed by the front end of the first outer conductor and the rear end of the second outer conductor that overlaps the front end of the first outer conductor. The overlapping portion has an auxiliary portion that assists in assembling the connector.

[0010] According to this configuration, by providing the auxiliary portion in the overlapping portion, the first outer conductor and the second outer conductor can be easily assembled.

[0011] (2) It is preferable that the auxiliary portion has a first protruding portion provided on the first outer conductor and protruding radially outward, and a locking portion provided on the second outer conductor and locking with the first protruding portion. With this configuration, the first protruding portion locks with the locking portion, which makes it easier to stabilize the relative positions of the first outer conductor and the second outer conductor, and makes it easier to assemble the first outer conductor and the second outer conductor.

[0012] (3) In (2), it is preferable that a slit extending forward from the rear end of the second outer conductor is formed on each of both circumferential sides of the locking portion. With this configuration, when the second outer conductor is fitted onto the end of the first outer conductor, the locking portion can be elastically deformed outward, making it easier for the locking portion to be locked onto the first protruding portion.

[0013] (4) The connector further includes a housing into which the second outer conductor is inserted, and the second outer conductor is inserted into the housing from the rear. Preferably, the auxiliary portion has a second protrusion provided on the second outer conductor, protruding radially outward, to prevent the second outer conductor from being inserted beyond the correct insertion position relative to the housing. This configuration allows the second outer conductor to be provided with the second protrusion while the first outer conductor ensures the shielding function of the overlapping portion, so the shape of the second protrusion can be determined without considering the shielding function. This allows for greater flexibility in the shape of the second protrusion.

[0014] (5) In (4), the auxiliary portion is provided on the second outer conductor and has a third protrusion protruding radially outward, and the third protrusion and the second protrusion are arranged side by side in the circumferential direction of the second outer conductor. The housing preferably has accommodating portions that are recessed to correspond to the third protrusion and the second protrusion and accommodate the third protrusion and the second protrusion, respectively. This configuration makes it possible to prevent components provided with protrusions other than the second protrusion and the third protrusion (i.e., components provided with protrusions that do not correspond to the accommodating portions) from being inserted into the housing.

[0015] (6) In (5), which indirectly cites (3), it is preferable that the second and third protrusions are formed by cutting and raising the second outer conductor radially outward, and that at least one of the second and third protrusions faces the slit. This configuration makes it possible to provide auxiliary parts with various functions while reducing the number of slits, thereby ensuring an area used to connect the first and second outer conductors in the overlapping part. In addition, it is easy to simplify the shape of the auxiliary parts.

[0016] [Details of the embodiments 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 8. In the following description, the right side in Figure 1 is defined as the front, and the left side as the rear. The top side in Figure 1 is defined as the top, and the bottom side as the bottom.

[0017] Configure Connector As shown in Fig. 1, the connector 10 includes a sleeve 11, an inner conductor 13, a dielectric 14, a first outer conductor 15A, a second outer conductor 15B, an overlapping portion 20, and a housing 16. The connector 10 is attached to the end of a shielded electric wire W. 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 and the housing 16 are made of synthetic resin.

[0018] The shielded wire W, which is a cable, is a so-called coaxial wire. The shielded wire W has a conductive core wire 51 made of multiple strands twisted together, an insulating coating 52 surrounding the core wire 51, a conductive braided wire 53 surrounding the coating 52 and made by weaving the strands into a mesh, and an insulating sheath 54 surrounding 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 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 54 and the coating 52.

[0019] The sleeve 11 is annular. The sleeve 11 is disposed so as to surround the outer periphery of the braided wire 53, and the outer surface thereof is covered by the tip end of the folded back braided wire 53. The sleeve 11 has a function of bearing 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-to-rear direction. The mating connection portion 13A is composed of a pair of elastic pieces 13D that protrude forward from the tubular portion 13B. The elastic pieces 13D are arranged opposite each other across the axis of the tubular portion 13B. When a tab (not shown) of a mating inner conductor is inserted between the elastic pieces 13D from the front, the elastic pieces 13D expand to guide the tab and sandwich it. The center 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 center conductor crimping portion 13C. The center conductor crimping portion 13C is crimped to the core wire 51, thereby connecting the inner conductor 13 and the core wire 51.

[0022] The dielectric 14 is cylindrical and has an inner conductor insertion hole 14A with a circular cross section that penetrates in the front-to-rear direction. The inner conductor 13 is inserted into the inner conductor insertion hole 14A of the dielectric 14 from the rear. As shown in Fig. 3, the inner conductor 13 is provided with a stopper portion 13E, which abuts against the front end of a stopper receiving portion 14C formed in the inner conductor insertion hole 14A from the rear, causing the inner conductor 13 to stop at the front with respect to the dielectric 14.

[0023] The first outer conductor 15A is formed into a cylindrical shape by bending a metal plate or the like. As shown in FIG. 4, the first outer conductor 15A has a first cylindrical portion 15C and a second cylindrical portion 15D. 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 that covers the tip end of the folded-back braided wire 53 (see FIG. 1). 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 wire W. The first outer conductor 15A is connected to the front end of the shielded wire W by being crimped onto the front end of the shielded wire W (see FIG. 1). The rear end of the dielectric 14 is disposed adjacent to the tip of the second tubular portion 15D (see FIG. 1).

[0024] The second cylindrical portion 15D of the first outer conductor 15A is provided with a pair of first protrusions 15S that protrude radially outward. These first protrusions 15S are arranged on opposite sides of the axis of the second cylindrical portion 15D. These first protrusions 15S are formed by cutting and raising a portion of the second cylindrical portion 15D. These first protrusions 15S are inclined rearward so that the distance between them increases. The rear ends of these first protrusions 15S are raised in a direction perpendicular to the axial direction.

[0025] The second outer conductor 15B is formed into a cylindrical shape by bending a metal plate or the like. As shown in Fig. 5, the second outer conductor 15B has a third cylindrical portion 15F and a fourth cylindrical portion 15G. 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 (see Fig. 1). The fourth cylindrical portion 15G is located forward of the third cylindrical portion 15F.

[0026] The rear end of the third cylindrical portion 15F of the second outer conductor 15B is provided with a pair of locking portions 15T, multiple slits 15W, a second protrusion 15U, and a third protrusion 15V. The pair of locking portions 15T are disposed on opposite sides of the axis of the third cylindrical portion 15F. Each of these locking portions 15T is formed by a pair of slits 15W. In other words, in the third cylindrical portion 15F, a slit 15W is formed on each of both circumferential sides of the locking portion 15T.

[0027] Each slit 15W is formed to extend forward from the rear end of the third tubular portion 15F. The locking portion 15T is a portion sandwiched between a pair of slits 15W. Each locking portion 15T has a through hole 15X formed therethrough in the plate thickness direction. Each locking portion 15T is elastically deformable radially outward with the front end (rear end) of the slit 15W as a fulcrum.

[0028] The second protrusions 15U are provided at the portions where the ends of the metal plates are butted together to form the second outer conductor 15B. Specifically, the second protrusions 15U are formed by cutting and raising a portion of each of the ends of the butted metal plates so that they rise radially outward in one and the other circumferential directions, and are adjacent to each other in the circumferential direction.

[0029] The third protrusion 15V is provided contiguous with one of the locking portions 15T. The third protrusion 15V is formed by cutting and raising a portion of the third tubular portion 15F so that it faces radially outward and rises in the circumferential direction. The third protrusion 15V rises radially outward from one circumferential side of one of the locking portions 15T. The third protrusion 15V faces the slit 15W. In other words, the outer shape of one of the locking portions 15T and the outer shape of the third protrusion 15V face a common single slit 15W.

[0030] The second protrusion 15U and the third protrusion 15V are arranged side by side in the circumferential direction on the third cylindrical portion 15F of the second outer conductor 15B. The second protrusion 15U and the third protrusion 15V are arranged on one side of the third cylindrical portion 15F divided in half in the circumferential direction by the pair of locking portions 15T. The thickness of the second protrusion 15U in the circumferential direction of the third cylindrical portion 15F is greater than the thickness of the third protrusion 15V. The fourth cylindrical portion 15G is provided with a plurality of contact portions 15H that come into contact with the inner surface of a cylindrical mating outer conductor (not shown).

[0031] The dielectric 14 is inserted into the second outer conductor 15B from the rear (see FIG. 1). As shown in FIG. 6, a protrusion 15R that protrudes inward is provided on the third tubular portion 15F of the second outer conductor 15B. This protrusion 15R abuts from the front against the rear end of a recess 14D formed on the outer surface of the dielectric 14, thereby preventing the dielectric 14 from reaching the front of the second outer conductor 15B. The second outer conductor 15B is coaxially connected to the front end of the first outer conductor 15A and is arranged to extend forward of the shielded wire W (see FIG. 1).

[0032] 6 and 7, the overlapping portion 20 is a portion in which the second outer conductor 15B is fitted over the front end portion of the first outer conductor 15A, and is formed by the front end portion of the first outer conductor 15A and the rear end portion of the second outer conductor 15B overlapping the front end portion of the first outer conductor 15A. The overlapping portion 20 has an auxiliary portion 20A that assists in assembling the connector 10. The auxiliary portion 20A has the above-mentioned pair of first protrusions 15S, a pair of locking portions 15T, a second protrusion 15U, and a third protrusion 15V. A slit 15W is formed on each of both circumferential sides of the locking portion 15T in the overlapping portion 20 (see FIG. 6).

[0033] The overlapping portion 20 is formed by fitting the second cylindrical portion 15D of the first outer conductor 15A into the third cylindrical portion 15F of the second outer conductor 15B. At this time, the pair of locking portions 15T of the third cylindrical portion 15F ride on the first protruding portions 15S of the second cylindrical portion 15D and elastically deform radially outward. Then, each of the elastically deformed locking portions 15T returns to its original position when the rear end of each of the first protruding portions 15S enters the through hole 15X of each of the locking portions 15T (see FIG. 7). In this way, the first protruding portions 15S are locked to the locking portions 15T. By engaging the first protrusion 15S with the engaging portion 15T, the second outer conductor 15B is coaxially connected to the front end of the first outer conductor 15A and extends forward of the shielded wire W, and the outer surface of the second tubular portion 15D and the inner surface of the third tubular portion 15F are kept in contact with each other.

[0034] The first outer conductor 15A and the second outer conductor 15B are connected by spot welding at a plurality of different positions in the overlapping portion 20 where the locking portions 15T, the slits 15W, the second protrusions 15U, and the third protrusions 15V are not formed. Here, the regions of the overlapping portion 20 where the locking portions 15T, the slits 15W, the second protrusions 15U, and the third protrusions 15V are not formed are regions of the overlapping portion 20 where the third tubular portion 15F and the second tubular portion 15D are both maintained in a cylindrical shape. In this way, the first protrusions 15S and the locking portions 15T function as auxiliary portions 20A that assist in assembling the first outer conductor 15A and the second outer conductor 15B.

[0035] As shown in Figure 1, the housing 16 is formed in the shape of a block that extends long in the front-to-rear direction and has a cavity 16A that penetrates it in the front-to-rear direction. The housing 16 is designed to be matable with a mating housing (not shown). A lock arm 16B is provided on the top surface of the housing 16 in an elastically deformable manner. The lock arm 16B elastically engages with a locking portion of the mating housing (not shown) and has the function of maintaining the housing 16 and the mating housing in a mated state.

[0036] As shown in FIG. 2, the housing 16 has a storage portion 16C. The storage portion 16C has a first groove 16D that communicates with the cavity 16A and extends in the front-rear direction, and a second groove 16E that communicates with the cavity 16A and extends in the front-rear direction (see FIGS. 3 and 8). The first groove 16D and the second groove 16E are recessed in a direction away from the axis of the cavity 16A. The first groove 16D and the second groove 16E are arranged side by side in the circumferential direction on the upper side of the inner surface of the cavity 16A. The width of the first groove 16D in the circumferential direction of the inner surface of the cavity 16A is greater than the width of the second groove 16E.

[0037] The front ends of the first groove 16D and the second groove 16E are closed at the center of the housing 16 in the front-rear direction (see FIGS. 3 and 8). The rear ends of the first groove 16D and the second groove 16E are open to the rear surface of the housing 16 (see FIG. 2). In the front-rear direction, the front ends of the first groove 16D and the second groove 16E are aligned.

[0038] The shielded wire W, to which the sleeve 11, inner conductor 13, dielectric 14, first outer conductor 15A, and second outer conductor 15B are attached, is inserted from the rear into the cavity 16A of the housing 16. At this time, the second outer conductor 15B is inserted into the cavity 16A of the housing 16 from the rear of the housing 16. Then, the second protrusion 15U is inserted from the rear into the first groove 16D, and the third protrusion 15V is inserted from the rear into the second groove 16E. In other words, the accommodating portion 16C is recessed to correspond to the third protrusion 15V and the second protrusion 15U, and accommodates the third protrusion 15V and the second protrusion 15U, respectively.

[0039] 1, a lance 16F that protrudes forward in a cantilevered manner is provided on the lower wall of cavity 16A of housing 16. Lance 16F has a locking projection 16G at its tip (front end) that protrudes into cavity 16A. The front end of locking projection 16G forms locking surface 16H that rises steeply in the vertical direction.

[0040] A retainer insertion hole 16J that opens in a direction intersecting (orthogonal to) the cavity 16A is formed through the lower wall of the housing 16 around the lance 16F. A retainer (not shown) is inserted into the retainer insertion hole 16J from below.

[0041] [Inserting the shielded wire into the housing] The operation of inserting the shielded wire W, which has the sleeve 11, inner conductor 13, dielectric 14, first outer conductor 15A, and second outer conductor 15B attached thereto, into the housing 16 will be described. First, the shielded wire W is placed at the rear of the housing 16 so that the tip of the fourth cylindrical portion 15G of the second outer conductor 15B abuts against the tip. At this time, the cavity 16A of the housing 16 and the second outer conductor 15B are coaxially placed, and the second protrusion 15U is placed behind the first groove 16D, and the third protrusion 15V is placed behind the second groove 16E.

[0042] Then, the fourth cylindrical portion 15G of the second outer conductor 15B is inserted into the cavity 16A of the housing 16. As the insertion of the second outer conductor 15B into the cavity 16A progresses, the second protrusion 15U is inserted into the first groove 16D from the rear, and the third protrusion 15V is inserted into the second groove 16E from the rear (see FIG. 2). As the insertion of the second outer conductor 15B into the cavity 16A progresses, the second protrusion 15U moves forward within the first groove 16D. Then, the third protrusion 15V moves forward within the second groove 16E.

[0043] As a result, the front end of the third tubular portion 15F comes into contact with the locking projection 16G of the lance 16F. The lance 16F is pushed downward by the third tubular portion 15F and elastically deforms. When the rear end of the third tubular portion 15F reaches a position forward of the locking surface 16H of the locking projection 16G, the elastically deformed lance 16F returns to its original position (see FIG. 1).

[0044] As the second outer conductor 15B is further inserted into the cavity 16A, the second protrusion 15U abuts against the front end of the first groove 16D, and the third protrusion 15V abuts against the front end of the second groove 16E (see FIGS. 3 and 8). Thus, the second protrusion 15U and the third protrusion 15V are stopped by the first groove 16D and the second groove 16E, preventing the second outer conductor 15B from being inserted beyond the correct insertion position into the housing 16. In other words, the second protrusion 15U and the third protrusion 15V function as an auxiliary portion 20A that assists in assembling the connector 10 by preventing the second outer conductor 15B from being inserted beyond the correct insertion position into the housing 16. The second outer conductor 15B is then retained by the lance 16F.

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

[0046] The connector 10 of the present disclosure includes a first outer conductor 15A, a second outer conductor 15B, and an overlapping portion 20. The first outer conductor 15A is cylindrical and is crimped to the front end of the shielded wire W. The second outer conductor 15B is cylindrical and is coaxially fitted around the front end of the first outer conductor 15A, extending forward of the first outer conductor 15A. The overlapping portion 20 is composed of the front end of the first outer conductor 15A and a rear end of the second outer conductor 15B that overlaps the front end of the first outer conductor 15A. The overlapping portion 20 has an auxiliary portion 20A that assists in assembling the connector 10. With this configuration, the provision of the auxiliary portion 20A in the overlapping portion 20 makes it easy to assemble the first outer conductor 15A and the second outer conductor 15B.

[0047] The auxiliary part 20A of the connector 10 of the present disclosure has a first protruding part 15S provided on the first outer conductor 15A and protruding radially outward, and a locking part 15T provided on the second outer conductor 15B and locking with the first protruding part 15S. With this configuration, the first protruding part 15S locks with the locking part 15T, which makes it easier to stabilize the relative positions of the first outer conductor 15A and the second outer conductor 15B, and allows the first outer conductor 15A and the second outer conductor 15B to be easily assembled.

[0048] In the connector 10 of the present disclosure, a slit 15W extending forward from the rear end of the second outer conductor 15B is formed on each of both circumferential sides of the locking portion 15T. With this configuration, when the second outer conductor 15B is fitted onto the end of the first outer conductor 15A, the locking portion 15T is elastically deformed outward, making it easier for the locking portion 15T to be locked onto the first protruding portion 15S.

[0049] The connector 10 of the present disclosure further includes a housing 16 into which the second outer conductor 15B is inserted, and the second outer conductor 15B is inserted into the housing 16 from the rear. The auxiliary portion 20A is provided on the second outer conductor 15B and protrudes radially outward. The auxiliary portion 20A has a second protrusion 15U that prevents the second outer conductor 15B from being inserted beyond the correct insertion position into the housing 16. With this configuration, the shielding function of the overlapping portion 20 is ensured by the first outer conductor 15A, while the second outer conductor 15B can be provided with the second protrusion 15U. This allows the shape of the second protrusion 15U to be determined without considering the shielding function. This allows for greater flexibility in the shape of the second protrusion 15U.

[0050] Auxiliary portion 20A of connector 10 of the present disclosure is provided on second outer conductor 15B and has third protrusion 15V protruding radially outward, with third protrusion 15V and second protrusion 15U arranged side by side in the circumferential direction of second outer conductor 15B. Housing 16 has accommodating portions 16C formed to be recessed corresponding to third protrusion 15V and second protrusion 15U, and accommodating third protrusion 15V and second protrusion 15U, respectively. This configuration makes it possible to prevent components provided with protrusions other than second protrusion 15U and third protrusion 15V (i.e., components provided with protrusions that do not correspond to accommodating portions 16C) from being inserted into housing 16.

[0051] The second protrusion 15U and the third protrusion 15V of the connector 10 of the present disclosure are formed by cutting and raising the second outer conductor 15B radially outward, with the third protrusion 15V facing the slit 15W. This configuration makes it possible to provide auxiliary portions 20A with various functions while limiting the number of slits 15W, thereby ensuring an area in the overlapping portion 20 used to connect the first outer conductor 15A and the second outer conductor 15B. In addition, the shape of the auxiliary portions 20A can be easily simplified.

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

[0053] Unlike the first embodiment, the second protrusion may be provided continuously with one of the locking portions, and the third protrusion may be provided by utilizing the portion where the ends of the metal plates are butted together to form the second outer conductor.

[0054] The number of locking portions and first protrusions is not limited to that in the first embodiment, and may be one, or three or more.

[0055] Unlike the first embodiment, the third protrusion may be provided continuously with one of the locking portions, and the second protrusion may be provided continuously with the other locking portion. In other words, the second protrusion may have the same configuration as the third protrusion, and the second protrusion and the third protrusion may face the slit.

[0056] Unlike the first embodiment, a twisted pair wire or the like may be used instead of the shielded wire. [Explanation of symbols]
