[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 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 coaxially fitted around the front end of the first outer conductor and extends 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 overlapping 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 with which the first protruding portion is locked. With this configuration, the first protruding portion is locked to the locking portion, which makes it easier to stabilize the relative positions of the first outer conductor and the second outer conductor, and the first outer conductor and the second outer conductor can be easily assembled.

[0012] (3) In (2), it is preferable that a slit extending forward from a 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 of the housing. The auxiliary portion preferably has a second protrusion provided on the second outer conductor, protruding radially outward, and preventing the second outer conductor from being inserted beyond a normal insertion position relative to the housing. With this configuration, the second protrusion can be provided on the second outer conductor while the shielding function in the overlapping portion is ensured by the first outer conductor, so that the shape of the second protrusion can be determined without considering the shielding function. This makes it easier to give freedom to the shape of the second protrusion.

[0014] (5) In (4), the auxiliary portion has a third protrusion provided on the second outer conductor and 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. It is preferable that the housing has accommodating portions formed to be recessed corresponding to the third protrusion and the second protrusion, and each of the third protrusion and the second protrusion is accommodated therein. With this configuration, it is possible to prevent a component provided with a protrusion other than the second protrusion and the third protrusion (i.e., a component provided with a protrusion that does not correspond to the accommodating portions) from being inserted into the housing.

[0015] (6) In (5) which indirectly quotes (3), it is preferable that the second and third protrusions are formed by cutting and raising the second outer conductor radially outward, and at least one of the second and third protrusions faces the slit. With this configuration, it is possible to provide auxiliary parts having various functions while reducing the number of slits, so that an area used for connecting the first and second outer conductors in the overlapping part can be secured. In addition, it is easy to simplify the shape of the auxiliary parts.

[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 Figs. 1 to 8. In the following description, the front and rear directions are the same as those in Fig. 1. left In front, right Regarding the up-down direction, the upper side in Fig. 1 is defined as the upper side, and the lower side is defined as the lower side.

[0017] [Connector configuration] 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 an 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 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 in a net shape, and an insulating sheath 54 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 is configured such that 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 to surround the outer periphery of the braided wire 53, and the outer surface of the sleeve 11 is covered by the tip of the folded back 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 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. The elastic pieces 13D are arranged opposite each other across the axis of the tubular portion 13B. When a tab (not shown) of the mating inner conductor is inserted between the elastic pieces 13D from the front, the elastic pieces 13D open to guide the tab and sandwich the tab. The central conductor crimping portion 13C has an open barrel shape and is connected to the rear end of the tubular portion 13B. An 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, 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-rear direction. The inner conductor 13 is inserted from the rear into the inner conductor insertion hole 14A of the dielectric 14. As shown in Fig. 3, 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] 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 covered by the tip portion of the folded back braided wire 53 (see FIG. 1). The second cylindrical portion 15D is arranged 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 front end of the shielded electric wire W by being crimped (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 protruding portions 15S protruding radially outward. These first protruding portions 15S are disposed on opposite sides of the axis of the second cylindrical portion 15D. These first protruding portions 15S are formed by cutting and raising a part of the second cylindrical portion 15D. These first protruding portions 15S are inclined toward the rear so that the distance between them increases. The rear ends of these first protruding portions 15S are steeply erected 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] A pair of locking portions 15T, a plurality of slits 15W, a second protrusion 15U, and a third protrusion 15V are provided at the rear end of the third cylindrical portion 15F of the second outer conductor 15B. 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 extending 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 is formed with a through hole 15X penetrating 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 protruding portion 15U is provided at a portion where the ends of the metal plates are butted together to form the second outer conductor 15B. Specifically, the second protruding portions 15U are formed by cutting and raising a part of each of the ends of the butted metal plates so as to 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 continuously with one of the locking portions 15T. The third protrusion 15V is formed by cutting and raising a part of the third tubular portion 15F so as to face outward in the radial direction and rise in the circumferential direction. The third protrusion 15V rises outward in the radial direction from one side in the circumferential direction in 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 mating outer conductor (not shown) formed in a cylindrical shape.

[0031] The dielectric 14 is inserted into the second outer conductor 15B from the rear (see FIG. 1). As shown in FIG. 6, a protruding portion 15R protruding inward is provided on the third tubular portion 15F of the second outer conductor 15B. This protruding portion 15R abuts from the front against the rear end of the recessed portion 14D formed on the outer surface of the dielectric 14, so that the dielectric 14 is stopped at the front with respect to the second outer conductor 15B. The second outer conductor 15B is arranged so as to be coaxially connected to the front end portion of the first outer conductor 15A and 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 onto the front end portion of the first outer conductor 15A, and which is constituted 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. The slits 15W are formed on both sides of the locking portion 15T in the circumferential direction of the overlapping portion 20 (see FIG. 6).

[0033] The overlapping portion 20 is formed by fitting the second tubular portion 15D of the first outer conductor 15A into the third tubular portion 15F of the second outer conductor 15B. At this time, the pair of locking portions 15T of the third tubular portion 15F ride on the first protruding portion 15S of the second tubular portion 15D and are elastically deformed 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 portion 15S with the engaging portion 15T, the second outer conductor 15B is coaxially connected to the front end portion of the first outer conductor 15A and extends forward of the shielded wire W, and a state in which the outer surface of the second tubular portion 15D and the inner surface of the third tubular portion 15F are in contact with each other is maintained.

[0034] The first outer conductor 15A and the second outer conductor 15B are connected to each other by spot welding at different positions in the overlapping portion 20 where the locking portion 15T, the slit 15W, the second protruding portion 15U, and the third protruding portion 15V are not formed. Here, the area in the overlapping portion 20 where the locking portion 15T, the slit 15W, the second protruding portion 15U, and the third protruding portion 15V are not formed is the area in the overlapping portion 20 where the third tubular portion 15F and the second tubular portion 15D are both maintained in a cylindrical shape. Thus, the first protruding portion 15S and the locking portion 15T function as an auxiliary portion 20A that assists in assembling the first outer conductor 15A and the second outer conductor 15B.

[0035] As shown in Fig. 1, the housing 16 is shaped like a block that extends long in the front-rear direction and has a cavity 16A that penetrates the housing 16 in the front-rear direction. The housing 16 can be fitted into a mating housing (not shown). A lock arm 16B is provided on the upper surface of the housing 16 so as to be elastically deformable. 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 fitted 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 larger 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 in the front-rear direction of the housing 16 (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, the inner conductor 13, the dielectric 14, the first outer conductor 15A, and the 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. That is, the accommodation portion 16C is formed to be recessed corresponding to the third protrusion 15V and the second protrusion 15U, and accommodates each of the third protrusion 15V and the second protrusion 15U.

[0039] 1, a lance 16F that protrudes forward in a cantilever shape is provided on the bottom wall of the cavity 16A of the housing 16. The lance 16F has a locking projection 16G at its tip (front end) that protrudes into the cavity 16A. The front end of the locking projection 16G forms a 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 penetrating 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] [About inserting the shielded wire into the housing] The operation of inserting the shielded wire W, to which the sleeve 11, the inner conductor 13, the dielectric 14, the first outer conductor 15A, and the second outer conductor 15B are attached, into the housing 16 will be described. First, the fourth cylindrical portion 15G of the second outer conductor 15B is arranged so that the tip of the fourth cylindrical portion 15G faces the rear of the housing 16. At this time, the cavity 16A of the housing 16 and the second outer conductor 15B are arranged coaxially, and the second protruding portion 15U is arranged behind the first groove 16D, and the third protruding portion 15V is arranged 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 proceeds, 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 proceeds, the second protrusion 15U moves forward within the first groove 16D. Then, the third protrusion 15V moves forward within the second groove 16E.

[0043] Then, 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. Then, 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] Further, when the second outer conductor 15B is inserted further 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, and the second outer conductor 15B is prevented from being inserted beyond the correct insertion position relative to the housing 16. In other words, the second protrusion 15U and the third protrusion 15V function as an auxiliary part 20A that assists in assembling the connector 10 by preventing the second outer conductor 15B from being inserted beyond the correct insertion position relative to the housing 16. The second outer conductor 15B is prevented from coming off 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 electric wire W. The second outer conductor 15B is cylindrical and is coaxially fitted around the front end of the first outer conductor 15A and extends forward of the first outer conductor 15A. The overlapping portion 20 is composed of the front end of the first outer conductor 15A and the rear end of the second outer conductor 15B overlapping 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. According to this configuration, the first outer conductor 15A and the second outer conductor 15B can be easily assembled by providing the auxiliary portion 20A to the overlapping portion 20.

[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 is locked with the locking part 15T, so that the relative positions of the first outer conductor 15A and the second outer conductor 15B are easily stabilized, and the first outer conductor 15A and the second outer conductor 15B can 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 can be elastically deformed outward, making it easier for the locking portion 15T to be locked to 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 of the housing 16. The auxiliary portion 20A has a second protruding portion 15U that is provided on the second outer conductor 15B and protrudes radially outward to prevent the second outer conductor 15B from being inserted beyond a normal insertion position into the housing 16. With this configuration, the second protruding portion 15U can be provided on the second outer conductor 15B while the shielding function in the overlapping portion 20 is ensured by the first outer conductor 15A, so that the shape of the second protruding portion 15U can be determined without considering the shielding function. This makes it easy to give freedom to the shape of the second protruding portion 15U.

[0050] The auxiliary part 20A of the connector 10 of the present disclosure has a third protrusion 15V provided on the second outer conductor 15B and protruding radially outward, and the third protrusion 15V and the second protrusion 15U are arranged side by side in the circumferential direction of the second outer conductor 15B. The housing 16 has a receiving section 16C formed to be recessed corresponding to the third protrusion 15V and the second protrusion 15U, and receiving each of the third protrusion 15V and the second protrusion 15U. This configuration makes it possible to prevent a component provided with a protrusion other than the second protrusion 15U and the third protrusion 15V (i.e., a component provided with a protrusion that does not correspond to the receiving section 16C) from being inserted into the 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, and the third protrusion 15V faces the slit 15W. With this configuration, it is possible to provide the auxiliary portion 20A having various functions while reducing the number of slits 15W, so that it is possible to secure an area used for connecting the first outer conductor 15A and the second outer conductor 15B in the overlapping portion 20. In addition, it is easy to simplify the shape of the auxiliary portion 20A.

[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 second protrusion may be provided contiguous to one of the locking portions, and a 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 protruding portions is not limited to the number in the first embodiment, and may be one, or three or more.
