[0004] In the case of the structure of Patent Document 1, in order to facilitate the insertion of each side plate portion between each side wall portion, the outer dimensions of a pair of side plates (the distance between the left and right outer surfaces of each side plate portion) are preferably set smaller than the inner dimensions of each side wall portion (the distance between the left and right inner surfaces of each side wall portion). However, if such dimension setting is adopted, due to assembly deviation, it is possible to manufacture shielding terminals in which the side wall portion and the side plate portion are in contact and shielding terminals in which they are not in contact, and there is a concern that the transmission performance of the signal in the shielding terminal will vary.
[0005] Therefore, an object of the present invention is to provide a shielding terminal which can suppress the deviation of signal transmission performance and improve the signal transmission performance. Solutions to Solve Problems

The first outer conductor includes a bottom plate portion, a pair of left and right first side plate portions extending upward from the bottom plate portion, and an opening portion formed between upper ends of the first side plate portions. The second outer conductor includes a cover portion covering the opening and a pair of left and right second side plate portions extending downward from the cover portion. Each of the second side plates has a curved portion, which is disposed above the bottom plate and between the first side plates and is curved outward in the left-right direction from the upper end to the lower end. The lower end portions of the bent portions are in contact with the upper surface of the bottom plate portion in a mutually abutting state. The middle portion of each of the bent portions in the extending direction of each of the second side plate portions is in contact with the opposing inner surfaces of each of the first side plate portions.

[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. (1) A shield terminal comprising a first outer conductor and a second outer conductor that can be connected to each other, The first outer conductor includes a bottom plate portion, a pair of left and right first side plate portions extending upward from the bottom plate portion, and an opening portion formed between upper ends of the first side plate portions. The second outer conductor includes a cover portion covering the opening and a pair of left and right second side plate portions extending downward from the cover portion. Each of the second side plates has a curved portion, which is disposed above the bottom plate and between the first side plates and is curved outward in the left-right direction from the upper end to the lower end. The lower end portions of the bent portions are in contact with the upper surface of the bottom plate portion in a mutually abutting state. The middle portion of each of the bent portions in the extending direction of each of the second side plate portions is in contact with the opposing inner surfaces of each of the first side plate portions.
[0010] The shield terminal of (1) can make the second outer conductor elastically contact with the first outer conductor by the bent portion, so that the contact state between the first outer conductor and the second outer conductor can be achieved and maintained with high reliability regardless of dimensional variations or assembly variations of the components.
[0011] (2) In the shield terminal described in (1), each of the bent portions forms an air layer between at least one of the center conductors of the shielded electric wire disposed between dielectric bodies disposed between the pair of second side plate portions.
[0012] The shield terminal of (2) can increase the impedance of the bent portion by forming an air layer, so that the impedance of the bent portion can be easily adjusted.
[0013] (3) In the shield terminal described in (1) or (2), the lower end portion of each of the second side plate portions extends in the front-rear direction, A protrusion that protrudes downward from other parts except for the part is provided at a part in the front-rear direction of the lower end of each of the second side plates, The protrusions are butted against each other and are located at the lower end of the bent portion.
[0014] The shield terminal of (3) is provided with a protrusion protruding downward more than other parts except a part at a part of the lower end part extending in the front-back direction of each second side plate part, so when the lower end parts of a pair of second side plate parts are butted together using a crimping machine, the pressing force of the crimping machine is easily concentrated on the protrusion parts, so that a bent part is formed at the position of the protrusion part (i.e., a part). Therefore, by changing the position of a part of the lower end part of the second side plate part, it is easy to set the position of the bent part at a desired position in the front-back direction.
[0015] [Details of Embodiments of the Invention] <Implementation Method 1> Reference Figures 1 to 6 Embodiment 1 of the shield terminal 1 of the present invention will be described. In the figure, "front side", "rear side", "upper side", "lower side", "right side" and "left side" are represented by "F", "B", "U", "D", "R" and "L", respectively. In addition, the reference of the direction is defined for convenience and may not be consistent with the direction of the connector including the shield terminal 1 when it is mounted on a vehicle or the like. For example, the up and down direction is not limited to the direction of gravity.
[0016] [Structure of shield terminal] like Figure 1 As shown in FIG. 1 , the shield terminal 1 includes an inner conductor 10, a first dielectric body 11, a first outer conductor 12, a second outer conductor 13, a second dielectric body 14 as a dielectric body, and a shielded electric wire 70. The inner conductor 10 is formed by stamping a metal plate and has a shape that is elongated in the front-to-back direction as a whole. The inner conductor 10 includes a cylindrical main body 10A, a pair of elastic contact portions 10B that extend forward in a cantilevered manner from the main body 10A, and an open cylindrical crimping portion 10C that protrudes rearward from the main body 10A.
[0017] The first dielectric body 11 is made of synthetic resin and has a cylindrical shape with its axis oriented in the front-rear direction. The main body 10A and the elastic contact part 10B of the inner conductor 10 are accommodated in the first dielectric body 11. The crimping part 10C protrudes backward from the rear end surface of the first dielectric body 11.
[0018] The first outer conductor 12 is formed by stamping a metal plate and has an overall shape that is elongated in the front-to-back direction. Figure 2 As shown in FIG. 1 , the first outer conductor 12 includes a cylindrical shield portion 12A, a connection shield portion 12B, and a crimping shield portion 12C. The cylindrical shield portion 12A constitutes the front end portion of the first outer conductor 12 and is cylindrical in shape with its axis oriented in the front-rear direction. The main body portion 10A and the elastic contact portion 10B of the inner conductor 10 and the entire first dielectric body 11 are accommodated in the cylindrical shield portion 12A (see FIG. 1 ). Figure 1 ).
[0019] The connection shielding portion 12B includes a front wall portion 12D, a pair of first side plate portions 12E connected to both ends of the front wall portion 12D in the left-right direction and in a symmetrical flat plate shape, and a pair of stabilizing portions 12F in the left-right direction and in asymmetrical shape with different lengths in the front-back direction. The front wall portion 12D is connected to the lower half of the rear end edge of the cylindrical shielding portion 12A and extends from the outer periphery of the cylindrical shielding portion 12A in a flange shape. The lower end portion of the front wall portion 12D extends in the left-right direction (not shown). The left-right side edges of the front wall portion 12D extend in the up-down direction.
[0020] The pair of first side plate portions 12E are arranged in parallel and separated in the left-right direction with the plate thickness direction facing the left-right direction. The front end edge of each first side plate portion 12E is connected to both side edges of the front wall portion 12D in the left-right direction. The stabilizing portion 12F is formed so as to protrude upward from the front end portion of the upper end edge of each first side plate portion 12E and be folded back toward the left-right direction.
[0021] A connection space R defined by a pair of first side plate portions 12E is formed on the inner side of the connection shield portion 12B in the left-right direction. The crimping portion 10C of the inner conductor 10 is accommodated in the connection space R (see Figure 1 ). The upper surface of the connection shield 12B is formed as an opening portion that opens the connection space R to the outside and upward of the connection shield 12B, that is, the first opening 12G. The first opening 12G is formed between the upper ends of the pair of first side plates 12E. The first opening 12G is open over the entire area of the connection shield 12B in the front-rear direction.
[0022] The lower surface of the connection shield 12B is a second opening 12H that opens the connection space R to the outside and downward of the connection shield 12B. The connection shield 12B passes through the connection space R, the first opening 12G, and the second opening 12H, and is in a state of penetrating in the up-down direction. The opening range of the second opening 12H in the front-to-back direction is a region from a position behind the front end of the connection shield 12B to a position in front of the rear end of the connection shield 12B. That is, the opening size of the second opening 12H in the front-to-back direction is smaller than the opening size of the first opening 12G in the front-to-back direction.
[0023] A front bottom plate portion 12J and a rear bottom plate portion 12K as a bottom plate portion are provided on the lower surface of the connection shield portion 12B. The front bottom plate portion 12J is formed to extend in the left-right direction with the plate thickness direction facing the up-down direction. The front bottom plate portion 12J forms the front edge of the opening edge of the second opening portion 12H. The front end edge of the front bottom plate portion 12J is connected to the lower edge of the front wall portion 12D. Both ends of the front bottom plate portion 12J in the left-right direction are connected to the front end portion of the lower edge portion of each first side plate portion 12E. The front bottom plate portion 12J forms a right angle with each first side plate portion 12E. The front bottom plate portion 12J is formed in a form that is bridged between a pair of first side plates 12E (not shown).
[0024] The rear bottom plate portion 12K is formed in the same manner as the front bottom plate portion 12J, with the plate thickness direction oriented in the up-down direction and extending in the left-right direction. The rear bottom plate portion 12K forms the rear edge of the opening edge of the second opening portion 12H. Both ends of the rear bottom plate portion 12K in the left-right direction are vertically connected to the rear end portions of the lower edge portions of each first side plate portion 12E. The rear bottom plate portion 12K is formed in a form spanned between a pair of first side plate portions 12E. In other words, a pair of first side plate portions 12E extend upward from the rear bottom plate portion 12K. The rear bottom plate portion 12K also has the function of causing the protrusion 13H of the second outer conductor 13 described later to abut. The interval between the rear end edge of the front bottom plate portion 12J and the front end edge of the rear bottom plate portion 12K is the opening dimension of the second opening portion 12H in the front-to-back direction (refer to Figure 1 ).
[0025] The crimping shielding portion 12C includes a bottom wall portion 12L, a pair of left-right symmetrical supporting wall portions 12M, a pair of left-right shielding tightening pieces 12N, and a pair of left-right sheath tightening pieces 12P. The bottom wall portion 12L is connected to the rear end of the rear bottom plate portion 12K and extends rearward from the rear bottom plate portion 12K. The supporting wall portion 12M is connected to the rear end edge of each first side plate portion 12E and extends rearward from each first side plate portion 12E. The lower edge of the supporting wall portion 12M is connected to the front end portion of both side edges in the left-right direction of the bottom wall portion 12L. The rear end portion of each first side plate portion 12E, the rear bottom plate portion 12K, the front end portion of the bottom wall portion 12L, and each supporting wall portion 12M are box-shaped and open in two directions, upward and in the front-back direction.
[0026] The shielding clamping piece 12N extends upward from the front-to-back center of both left and right edges of the bottom wall 12L. The sheathing clamping piece 12P extends upward from the rear end of both left and right edges of the bottom wall 12L.
[0027] The second outer conductor 13 is formed by stamping a metal plate. Figure 3 As shown, the second outer conductor 13 includes a connection portion surrounding portion 13A whose lower surface and both front and rear surfaces are open, a shielding surrounding portion 13B, and a connection piece portion 13C.
[0028] In the second outer conductor 13 before being assembled to the first outer conductor 12, the connecting portion surrounding portion 13A includes a covering portion 13D with the plate thickness direction oriented in the up-down direction, and a pair of second side plate portions 13E that are separated from each other and extend downward from the left and right side edges of the covering portion 13D and are symmetrical to each other. The lower end portion of each second side plate portion 13E extends in the front-to-back direction. A locking hole 13F that penetrates in the plate thickness direction is formed in each second side plate portion 13E. A recess 13G that is recessed toward the covering portion 13D side is formed in the front-to-back center portion of the lower end portion (the protruding edge protruding from the covering portion 13D) of each second side plate portion 13E.
[0029] A protrusion 13H protruding downward (in a direction away from the covering portion 13D) is formed at the rear end of the lower end (protruding edge protruding from the covering portion 13D) of each second side plate portion 13E (i.e., a portion of the lower end of the second side plate portion 13E in the front-rear direction). The protrusion 13H protrudes downward more than the portion other than the rear end of the lower end (protruding edge protruding from the covering portion 13D) of each second side plate portion 13E (i.e., the portion other than a portion of the second side plate portion 13E).
[0030] The dimension of each second side plate 13E in the front-to-back direction is smaller than the opening dimension of the first opening 12G in the front-to-back direction (not shown). The opening dimension of the first opening 12G in the front-to-back direction is the dimension between the rear end of the cylindrical shielding portion 12A and the front end of the shielding clamping piece 12N (see Figure 1 ). The dimension of each second side plate portion 13E in the front-to-back direction is larger than the opening dimension of the second opening portion 12H in the front-to-back direction (not shown). The opening dimension of the second opening portion 12H in the front-to-back direction is the dimension between the rear end of the front bottom plate portion 12J and the front end of the rear bottom plate portion 12K (refer to Figure 1 ).
[0031] The shielding surrounding portion 13B is connected to the rear end of the covering portion 13D and extends rearward from the connecting portion surrounding portion 13A. In the second outer conductor 13 assembled before the first outer conductor 12, the shielding surrounding portion 13B is in an open cylindrical shape, and has a base 13J connected to the covering portion 13D and a pair of tightening portions 13K extending from the left and right side edges of the base 13J. The connecting piece 13C is in an arc shape, formed in a posture with the inner surface facing downward and the axis facing the front-back direction, and is arranged in front of the covering portion 13D and above the covering portion 13D. The rear end of the connecting piece 13C is connected to the connecting portion 13L extending upward from the front end edge of the covering portion 13D.
[0032] The second dielectric body 14 is made of synthetic resin and has the same shape as the connecting portion surrounding portion 13A. Figure 4 As shown in the figure, the second dielectric body 14 has an upper surface portion 14A in a horizontal plate shape and a pair of left and right side portions 14B extending downward from both side edges of the upper surface portion 14A in the left and right directions. The upper surface portion 14A overlaps with the lower surface of the cover portion 13D, and each side portion 14B overlaps with the inner surface of each second side plate portion 13E in the left and right directions. The second dielectric body 14 is maintained in a state of being assembled to the second outer conductor 13 by locking the locking protrusion 14C provided on the outer surface of the side portion 14B in the locking hole 13F of the second outer conductor 13.
[0033] like Figure 1 As shown, the shielded electric wire 70 is an electric wire of a known type, and includes a center conductor 71, a cylindrical insulator 72 surrounding the center conductor 71, a cylindrical shield layer 73 composed of a braided wire arranged along the outer periphery of the cylindrical insulator 72, and a sheath 74 surrounding the shield layer 73. At the front end of the shielded electric wire 70, the sheath 74 is removed, the front end of the shield layer 73 is exposed in a state of overlapping with the outer periphery of the cylindrical insulator 72, and the center conductor 71 protrudes forward in a state of being exposed from the front end of the cylindrical insulator 72.
[0034] [Example of assembling procedure of shield terminal] Next, an example of the assembly process of the shield terminal 1 is described. The first dielectric body 11 and the first outer conductor 12 are assembled in a state of surrounding the inner conductor 10. Figure 1 As shown in the figure, in the state where the first dielectric body 11 and the first outer conductor 12 are assembled, the inner conductor 10 is accommodated in the cylindrical shielding portion 12A, and the crimping portion 10C of the inner conductor 10 protrudes rearward from the first dielectric body 11 and is accommodated in the connection space R of the first outer conductor 12. Before and after the assembly process of the inner conductor 10 and the first outer conductor 12, the front end portion of the shielded electric wire 70 and the crimping shielding portion 12C of the first outer conductor 12 are connected. At this time, the shield clamping piece 12N is crimped and fastened to the outer periphery of the shield layer 73 of the shielded electric wire 70, and the sheath clamping piece 12P is crimped and fastened to the outer periphery of the sheath 74.
[0035] In the state where the shielded electric wire 70 and the first outer conductor 12 are connected, the center conductor 71 protruding forward from the cylindrical insulator 72 is accommodated in the connection space R. In the connection space R, the crimping portion 10C of the inner conductor 10 is tightly crimped to the center conductor 71. The crimping process of the center conductor 71 and the crimping portion 10C is performed by causing an anvil (not shown) and a crimper (not shown) of a crimping machine (not shown) to enter the connection space R from the first opening 12G and the second opening 12H, respectively.
[0036] After the first dielectric body 11, the inner conductor 10, and the shielded wire 70 are assembled to the first outer conductor 12, the second outer conductor 13 assembled with the second dielectric body 14 is assembled to the first outer conductor 12. The first outer conductor 12 and the second outer conductor 13 can be connected to each other. Figure 4 As shown, when the second outer conductor 13 is assembled to the first outer conductor 12, each second side plate portion 13E is made to extend downward from the covering portion 13D, and the connecting portion surrounding portion 13A is inserted into the first opening portion 12G from above the first outer conductor 12. Furthermore, the protrusion 13H of each second side plate portion 13E is made to abut against the upper surface of the rear bottom plate portion 12K. At this time, the outer sides of a pair of second side plate portions 13E in the left-right direction are smaller in size than the inner sides of a pair of first side plate portions 12E in the left-right direction. At this time, the second dielectric body 14 is adjacent to the front of the cylindrical insulator 72 (refer to Figure 1 ).
[0037] Next, in the connection space R, the second side plate portion 13E of the second outer conductor 13 and the side surface portion 14B of the second dielectric body 14 are punched into a shape surrounding the connection portion between the inner conductor 10 and the center conductor 71. This punching is performed by causing a die of a crimping machine (not shown) to enter the connection space R from the first opening 12G and the second opening 12H, respectively, and pressing the connection portion surrounding portion 13A from the top and bottom directions.
[0038] like Figure 5 As shown, when the press processing of the crimping machine is performed, each second side plate portion 13E is deformed in such a way that its lower end portion approaches each other toward the inner side in the left-right direction. Specifically, in each second side plate portion 13E, each protrusion 13H contacts the upper surface of the rear bottom plate portion 12K while approaching toward the inner side in the left-right direction, and then the lower end edges of each protrusion 13H are butted against each other.
[0039] The rear end of each second side plate portion 13E of the portion where the protrusion 13H is formed in the front-back direction is deformed in a manner that the central portion in the up-down direction bulges toward the left-right direction outer side, and elastically contacts the left-right direction inner surface of a pair of first side plate portions 12E. In this way, the curved portion 13M is formed at the rear end of each second side plate portion 13E, and the curved portion 13M is arranged above the rear bottom plate portion 12K and between each first side plate portion 12E, and is curved toward the right direction outer side from the upper end to the lower end. That is, each second side plate portion 13E has a curved portion 13M. The curved portion 13M is formed at the rear end of each second side plate portion 13E.
[0040] The protrusion 13H is located at the lower end of each curved portion 13M. The lower end of each curved portion 13M (the lower edge of the protrusion 13H) elastically contacts the upper surface of the rear bottom plate portion 12K in a mutually butted state. The middle portion of each curved portion 13M in the extending direction (up and down direction) of each second side plate portion 13E elastically contacts the inner surface (opposing inner surface) of each first side plate portion 12E in the left and right direction. The covering portion 13D covers the first opening portion 12G in a manner of covering it from above.
[0041] The other part of the second side plate 13E in the front-to-back direction except for the part where the protrusion 13H is provided (the part of the second side plate 13E that is forward of the protrusion 13H) is deformed by the press working of the crimping machine so as to be tilted downward toward the inner side in the left-right direction (see Figure 6 ).
[0042] The side surface 14B of the second dielectric body 14 is pressed inwardly in the left-right direction by the second side plate 13E. Therefore, the side surface 14B is deformed in the entire front-to-back direction so that the lower ends thereof approach each other inwardly in the left-to-right direction, and the lower ends thereof butt against each other. Thus, the central conductor 71 protruding forwardly from the cylindrical insulator 72 is surrounded by the second dielectric body 14.
[0043] Each bent portion 13M is separated from the side surface portion 14B of the second dielectric body 14 disposed between the pair of second side plate portions 13E (see Figure 5 An air layer 13N is formed between the inner surface of each curved portion 13M in the left-right direction and the outer surface of each side portion 14B in the left-right direction (see Figure 5 ).
[0044] The shield surrounding portion 13B of the second outer conductor 13 surrounds the shield clamping piece 12N and the bottom wall portion 12L fastened to the outer periphery of the shield layer 73, and is crimped to the outer periphery of the shield clamping piece 12N and the bottom wall portion 12L (see FIG. Figure 1 The connecting piece 13C is in elastic contact with the outer periphery of the rear end of the cylindrical shielding portion 12A from above (see Figure 1 ).
[0045] Next, the operation of the first embodiment will be described.
[0046] The shield terminal 1 includes a first outer conductor 12 and a second outer conductor 13 that can be connected to each other. The first outer conductor 12 includes a rear bottom plate portion 12K, a pair of left and right first side plates 12E extending upward from the rear bottom plate portion 12K, and a first opening portion 12G formed between the upper ends of the first side plates 12E. The second outer conductor 13 includes a covering portion 13D covering the first opening portion 12G and a pair of left and right second side plates 13E extending downward from the covering portion 13D. Each second side plate portion 13E includes a bent portion 13M, which is disposed above the rear bottom plate portion 12K and between the first side plates 12E, and is bent outward in the left-right direction from the upper end to the lower end. The lower end of each bent portion 13M has a portion that contacts the upper surface of the rear bottom plate portion 12K in a mutually butted state. The middle portion of each bent portion 13M in the extending direction of each second side plate portion 13E has a portion in contact with the opposing inner surface of each first side plate portion 12E.
[0047] According to this structure, the second outer conductor 13 can be brought into elastic contact with the first outer conductor 12 by the bent portion 13M, so that the contact between the first outer conductor 12 and the second outer conductor 13 can be achieved and maintained with high reliability regardless of dimensional and assembly variations of the components.
[0048] Each bent portion 13M forms an air layer 13N between the second dielectric body 14 disposed between the pair of second side plate portions 13E. According to this configuration, the impedance of the bent portion 13M can be increased by forming the air layer 13N, so that the impedance of the bent portion 13M can be easily adjusted.
[0049] The lower end of each second side plate portion 13E extends in the front-to-back direction, and a protrusion 13H that protrudes downward more than other parts except a part is provided in a part of the lower end of each second side plate portion 13E in the front-to-back direction, and each protrusion 13H is butted against each other and is located at the lower end of the bent portion 13M. According to this structure, since a protrusion 13H that protrudes downward more than other parts except a part is provided in a part of the lower end of each second side plate portion 13E extending in the front-to-back direction, when a pair of lower ends of the second side plate portions 13E are butted against each other by a press process using a crimping machine, the pressing force of the crimping machine is easily concentrated on the protrusions 13H, so that the bent portion 13M is formed at the position (i.e., a part) of the protrusion 13H. Therefore, by changing the position of a part of the lower end of the second side plate portion 13E, it is easy to set the position of the bent portion 13M at a desired position in the front-to-back direction.
[0050] <Other Implementation Methods> The embodiments disclosed herein are illustrative in all aspects and should not be construed as restrictive. 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 equivalent to the claims.
[0051] Unlike the first embodiment, the second dielectric body may not be provided. In this case, each bent portion is separated from the central conductor of the shielded wire disposed between the pair of second side plates to form an air layer. In addition, the second dielectric body may be disposed in the front-back direction so as to overlap with a portion of the bent portion. In this case, the bent portion forms an air layer between the dielectric body disposed between the pair of second side plates and between the central conductor of the shielded wire disposed between the pair of second side plates.
[0052] Unlike the first embodiment, a protrusion may be provided at the front end of the second side plate and the protrusion may be brought into contact with the upper surface of the front bottom plate and pressed to form a bent portion at the front end of the second side plate.
