[0010] [Explanation of Embodiments of the Invention] First, an embodiment of the present application will be explained.
[0011] The shield terminal of the present application, (1) has: an inner conductor connected to a front end portion of a shielded electric wire; a dielectric body that houses the inner conductor; a first outer conductor that receives the dielectric body; and a second outer conductor that is attached to the first outer conductor, the first outer conductor has a pair of first side walls that are opposed in a left-right direction and an opening portion formed between upper ends of the pair of first side walls, the second outer conductor has a cover wall that covers the opening portion from above, a pair of second side walls that are opposed in the left-right direction, and a crimping portion that is connected to a rear end portion of the cover wall, the crimping portion is crimped and connected to a shield portion of the shielded electric wire, the pair of first side walls each has a first opposed surface that faces rearward, the pair of second side walls each has a second opposed surface that is a front end surface and protrudes downward from the cover wall, and the second opposed surface is opposed to the first opposed surface.
[0012] According to the above (1), when the crimping portion of the second outer conductor is crimped to the shield portion of the shielded electric wire, the second opposed surface and the first opposed surface come into contact, and thus the crimping force is transmitted to each side wall, so that the second outer conductor can be prevented from being misaligned from the first outer conductor. In particular, since the second opposed surface is the front end surface of the second side wall, and is not a shape in which a portion of the outer conductor is largely cut out, the shielding performance can be maintained. Furthermore, the "opposed" includes a case in which the first opposed surface and the second opposed surface face each other with a spacing surface therebetween, and a case in which the first opposed surface and the second opposed surface face each other in a state of contact.
[0013] (2) In the shield terminal described in the above (1), it is preferable that the pair of first side walls each have a protruding portion that protrudes outward in the left-right direction, and the first opposed surface is a rear end surface of the protruding portion.
[0014] According to the above (2), the protruding amount of the protruding portion or the formation position of the protruding portion on the first side wall can be easily adjusted, and thus the design freedom of the first opposed surface is high.
[0015] (3) In the shield terminal described in the above (2), it is preferable that the protruding portion is disposed at a lower portion of each of the pair of first side walls.
[0016] According to the above (3), when the crimping portion of the second outer conductor is crimped to the shield portion of the shielded electric wire, the second opposed surface and the protruding portion that is away from the crimping portion come into contact, and thus the front end portion of the cover wall can be effectively prevented from being misaligned in a direction in which the front end portion is lifted with respect to the first outer conductor.
[0017] (4) In the shield terminal described in the above (3), it is preferable that the protruding portion has, in addition to a lower protruding portion that is disposed at the lower portion, an upper protruding portion that is disposed at an upper portion of each of the pair of first side walls, a rear end surface of the upper protruding portion also constitutes the first opposed surface that is opposed to the second opposed surface, and the first opposed surface of the upper protruding portion and the first opposed surface of the protruding portion are disposed on the same straight line in the up-down direction.
[0018] According to the above (4), in the process of mounting the second outer conductor to the first outer conductor, the second opposing surface of the second side wall can be made to follow the first opposing surface of the upper protrusion, and the first opposing surface of the upper protrusion can be used as a standard (reference) for determining the position of the front end of the second outer conductor. Thus, the mounting of the second outer conductor with respect to the first outer conductor can be easily performed.
[0019] (5) In the shield terminal according to any one of the above (1) to (4), it is preferable that the first opposing surface and the second opposing surface are both vertical surfaces extending in the up-down direction.
[0020] According to the above (5), the second outer conductor can be more reliably prevented from being misaligned from the first outer conductor when the crimping portion is crimped to the shield wire. [Details of Embodiments of the Invention] A specific example of an embodiment of the present application will be described below with reference to the drawings. Furthermore, the present application is not limited to this example, but is shown by the claims, and is intended to include all modifications within the meaning and range equivalent to the claims.
[0021] [Embodiment 1] Reference Figures 1 to 7 A specific example of Embodiment 1 of the present application will be described. As shown in Figure 1 , a shield terminal 10 is connected to a shield wire 11. As shown in Figure 2 , the shield terminal 10 has an inner conductor 12, a dielectric body 13, a first outer conductor 14, and a second outer conductor 15. The shield terminal 10 is housed in a housing that is not shown. A shield connector that is not shown is constituted by the shield terminal 10 and the housing. Furthermore, in Figure 1 , the X direction, the Y direction, and the Z direction respectively indicate the front direction, the left direction, and the up direction. In the following description, the up-down direction coincides with the height direction of the shield terminal 10. In addition, the left-right direction coincides with the width direction of the shield terminal 10. Furthermore, the reference of these directions does not necessarily coincide with the reference of the directions in the state in which the shield terminal 10 is mounted on a vehicle or the like that is not shown.
[0022] (The inner conductor 12 and the shield wire 11) The inner conductor 12 is made of an electrically conductive metal, and is not shown in detail, and has an overall shape that is elongated in the front-rear direction. As shown in Figure 1 , the inner conductor 12 has a tab 16 that protrudes in the front direction. The inner conductor 12 is connected to a core wire of the shield wire 11 that is not shown.
[0023] As shown in Figure 2 , the shield wire 11 has two covered wires 17 (in Figure 2The shield 19 is arranged between the sheath 18 and the covered electric wires 17. In the case of the present embodiment 1, the shield 19 is composed of a braided wire. The front end portion of the shield 19 is exposed by peeling of the sheath 18, and is folded back on a sleeve 48 arranged on the outer periphery side of the sheath 18. The sleeve 48 is arranged between the folded-back braided wire and the sheath 18, and receives the crimping force of a crimping portion 47 of the second outer conductor 15, which will be described later. In the case of the present embodiment 1, the two covered electric wires 17 are twisted pairs. The covered electric wires 17 are untwisted at positions exposed from the front end portion of the sheath 18. Although not shown, the front end portions of the covered electric wires 17 are exposed to the core wires by peeling of the insulating cover 20. The inner conductors 12 are connected to the exposed core wires. The inner conductors 12 are provided in two for each covered electric wire 17.
[0024] (Dielectric body 13) The dielectric body 13 is made of an insulating resin. As shown in Figure 3 , the dielectric body 13 is composed of a first dielectric body 21 and a second dielectric body 22. The second dielectric body 22 is arranged above the first dielectric body 21. The inner conductors 12 are arranged in the left-right direction and are housed between the first dielectric body 21 and the second dielectric body 22. The first dielectric body 21 has a side portion 23 protruding upward and retaining the second dielectric body 22.
[0025] The tab 16 of the shielded electric wire 11 is arranged protruding forward of the dielectric body 13. The covered electric wires 17 of the shielded electric wire 11 are arranged behind the dielectric body 13. An upper surface retaining portion 24, which is quadrangular in plan view, is recessed in the upper surface of the second dielectric body 22. As shown in Figure 2 , the upper surface retaining portion 24 is embedded and retained by the upper surface retaining portion 25 of the second outer conductor 15, which will be described later. As shown in Figure 3 , retaining portions 26, which are quadrangular in side view, are recessed in the left and right side surfaces of the second dielectric body 22. The retaining portions 26 can be embedded and retained by the retaining portions 27 of the first outer conductor 14, which will be described later.
[0026] In addition, a pair of stop portions 28 (only one is shown in Figure 3 ) extending in the up-down direction are provided protruding from the left and right side surfaces of the second dielectric body 22. As shown in Figure 6 , the stop portions 28 can abut against the rear end of the first outer conductor 14.
[0027] (First outer conductor 14) The first outer conductor 14 is made of an electrically conductive metal, and is formed by bending a metal plate by press working or the like. As shown in Figure 4As shown, the first outer conductor 14 has a bottom wall 29, an extension 30, a pair of first side walls 31, and a top wall 32. The bottom wall 29 is flat and extends in the front-back direction with the plate surface facing up and down. The extension 30 is strip-shaped and extends rearward from the left and right center portions at the rear end of the bottom wall 29.
[0028] Each first sidewall 31 is shaped to stand upright from the left and right ends of the bottom wall 29 so that the plate surface faces the left and right direction. Each first sidewall 31 and the bottom wall 29 have the same length in the front and back direction.
[0029] The upper wall 32 is flat and is positioned above the front portion of the bottom wall 29, opposite to the bottom wall 29. The upper wall 32 is connected between the upper ends of the front portions of each of the first side walls 31. The upper wall 32 has a side portion 33 extending from the upper end of one of the first side walls 31 toward the other, and another side portion 34 extending from the upper end of the other side toward one. The side portion 33 is longer than the other side portion 34 in the left-right direction.
[0030] One side portion 33 and the other side portion 34 are joined together at a position close to one side from the left and right center of the upper wall 32. The front portion of the bottom wall 29, the front portion of each of the first side walls 31, and the front portion of the upper wall 32 form a cylindrical portion 35 in the shape of a square tube. On each of the one side portion 33 and each of the first side walls 31, an elastic contact portion 36 is cut out and erected towards the inside of the cylindrical portion 35. Each elastic contact portion 36 is electrically connected to a square outer conductor (not shown) inserted into the inside of the cylindrical portion 35.
[0031] The first outer conductor 14 has a receiving space 37. The receiving space 37 is formed by the inner side of the cylindrical portion 35 and the space behind the cylindrical portion 35. The dielectric body 13 is received inside the receiving space 37. An opening 38 is formed between the upper ends of the first sidewalls 31. The opening 38 is formed in the portion between the upper ends of each of the first sidewalls 31, excluding the upper wall 32. The opening 38 is longer than the upper wall 32 in the front-back direction. Figure 1 As shown, the tab 16 of the inner conductor 12 protrudes and is disposed inside the cylindrical portion 35.
[0032] like Figure 4 As shown, each of the first sidewalls 31 has a pair of left and right locking portions 27, multiple locking portions 39, and a pair of left and right lower protrusions 40 (in Figure 4 (Only one side is shown in the diagram) and a pair of upper protrusions 41 on the left and right (in the diagram) Figure 4The locking portions 27 are formed by bending the plate portions arranged on the inner side of the cutout portions toward the accommodation space 37 at the rear end portions of the first side walls 31. The locking portions 27 extend while inclining from the rear end toward the front direction to the left and right directions, and are elastically deformable in the left and right directions. By inserting the dielectric body 13 into the accommodation space 37 from the rear, and by engaging the locking portions 27 with the locked portions 26 of the dielectric body 13, the dielectric body 13 is inhibited from falling out of the accommodation space 37 toward the rear. Further, by abutting the stop portions 28 against the rear end of the first outer conductor 14, the dielectric body 13 is inhibited from falling out of the accommodation space 37 toward the front.
[0033] The locked portions 39 are each arranged two in number between the elastic contact portions 36 and the locking portions 27, for example, in the front and rear directions with a space therebetween. The locked portions 39 each penetrate the first side wall 31 in the left and right directions (thickness direction). The locked portions 39 are each capable of locking the later-described locking portions 42 of the second outer conductor 15.
[0034] The lower and upper protruding portions 40 and 41 are portions corresponding to the protruding portions of the present application, and are arranged in the front portions of the first side walls 31, respectively. In the case of the present embodiment 1, the lower and upper protruding portions 40 and 41 are arranged between the elastic contact portions 36 and the locked portions 39 in the front and rear directions. The lower and upper protruding portions 40 and 41 are each formed by punching or beating processing such as louver processing, so as to protrude (bulge) to the outside in the left and right directions from a portion of the first side wall 31. In the case of the present embodiment 1, the lower and upper protruding portions 40 and 41 are each formed in the same shape and in the same size. The lower and upper protruding portions 40 and 41 each protrude by an amount of protrusion that is smaller than the thickness of the first side wall 31. Further, the lower and upper protruding portions 40 and 41 each protrude by an amount of protrusion that is smaller than the thickness of the later-described second side wall 43 of the second outer conductor 15. The lower protruding portions 40 are arranged lower than the upper protruding portions 41. The lower protruding portions 40 are arranged lower (lower portions) than the central portions in the up and down directions of the first side walls 31. The upper protruding portions 41 are arranged higher (upper portions) than the central portions in the up and down directions of the first side walls 31.
[0035] The lower and upper protruding portions 40 and 41 have first opposing surfaces 44 as end surfaces of the protruding portions. The first opposing surfaces 44 are, for example, cut surfaces cut at the time of louver processing, and are formed on the outer surfaces of the first side walls 31 along the cutting lines. The first opposing surfaces 44 are formed as vertical surfaces extending in the up and down directions. The first opposing surfaces 44 of the lower and upper protruding portions 40 and 41 are each arranged on the same straight line along the up and down directions (refer to FIG. 6). Figure 6The first opposing surface 44 corresponds to the rear end of the cylindrical portion 35. The first opposing surface 44 opposes a second opposing surface 45 of the second outer conductor 15 to be described later when the second outer conductor 15 is attached to the first outer conductor 14. The lower and upper protruding portions 40 and 41 gradually increase in size in the vertical direction from the front end toward the rear end (the first opposing surface 44) in side view. In the case of the present embodiment 1, the first opposing surface 44 is curved in rear view, and is edged by a straight line extending in the vertical direction and a circular arc curved outward in the lateral direction.
[0036] (Second outer conductor 15) The second outer conductor 15 is made of an electrically conductive metal and is formed by bending a metal plate by press working or the like. The second outer conductor 15 is attached to the first outer conductor 14 from above. As shown in FIG. 2, the second outer conductor 15 has a cover wall 46, a pair of second side walls 43, and a crimp portion 47. The cover wall 46 is flat and extends in the front-rear direction with the plate face facing in the vertical direction. Each of the second side walls 43 is flat and projects downward from the left and right ends of the cover wall 46 with the plate face facing in the lateral direction. Each of the second side walls 43 and the cover wall 46 have the same length in the front-rear direction. The crimp portion 47 is connected to the rear ends of the cover wall 46 and each of the second side walls 43. As shown in FIG. 2, the crimp portion 47 is crimped to the front end portion of the shielded electric wire 11 and is connected to the shield portion 19 folded back over the sleeve 48. As shown in FIG. 2, the crimp portion 47 has a base portion 49 connected to the cover wall 46 and each of the second side walls 43, and a pair of crimp pieces 50 (only one is shown) projecting downward from the base portion 49. Each of the crimp pieces 50 is disposed in opposition in the lateral direction. In the open state shown in FIG. 2, each of the crimp pieces 50 receives the shield portion 19 of the shielded electric wire 11, and after crimping, becomes a state of being wound around the outer peripheral surface of the shield portion 19. As shown in FIG. 2, the extension portion 30 is interposed between the tip end portion of each of the crimp pieces 50 and the shield portion 19. Figure 5 Figure 2 Figure 5 Figure 5 Figure 5 Figure 2
[0037] Figure 2
[0038] Figure 2 Figure 5 As shown, a housing locking portion 51 is formed at the front end of the cover wall 46. The housing locking portion 51 is positioned forward of the upper surface locking portion 25. The housing locking portion 51 is shaped to bulge upwards from a portion of the cover wall 46. The rear end of the housing locking portion 51 engages with a spear-shaped portion of the housing (not shown). Thus, the shielding terminal 10 is held in the housing.
[0039] like Figure 1 As shown, when the second outer conductor 15 is installed on the first outer conductor 14, each second sidewall 43 is arranged to cover each first sidewall 31 from the left and right sides of the first outer conductor 14. Figure 5 As shown, each of the second sidewalls 43 has a plurality of locking portions 42. Each locking portion 42 protrudes inward in the left-right direction of the second outer conductor 15. Each locking portion 42 is shaped such that a portion of each of the second sidewalls 43 bulges inward in the left-right direction. Each locking portion 42 is arranged at intervals in the front-back direction corresponding to each locked portion 39. Each locking portion 42 is configured to engage with each locked portion 39 of the first outer conductor 14.
[0040] Each second sidewall 43 has a second opposing surface 45 as its front end face. The second opposing surface 45 is a vertical surface extending in the vertical direction. The second opposing surface 45 is the foremost surface of the second outer conductor 15. When the second outer conductor 15 is mounted on the first outer conductor 14, the second opposing surface 45 is opposite to the first opposing surface 44.
[0041] (Function of shielding terminal 10) Next, an example of the assembly steps for the shielding terminal 10 will be described. When connecting the inner conductors 12 and the shielded wires 11, the two inner conductors 12 are connected to the core wires exposed at the front end of each shielded wire 17. Each inner conductor 12 is inserted into the second dielectric body 22. Then, the first dielectric body 21 is covered on the second dielectric body 22, and each inner conductor 12 is sandwiched and held between the first dielectric body 21 and the second dielectric body 22 (see reference). Figure 3 ).
[0042] The dielectric body 13, containing the inner conductor 12, is inserted into the receiving space 37 from behind the first outer conductor 14. The dielectric body 13 moves forward along the upper surfaces of the extension 30 and the bottom wall 29, respectively. When the dielectric body 13 is installed on the first outer conductor 14, each locking part 27 is inserted into each locking part 26, and each stop part 28 abuts against the rear end of the first outer conductor 14. At this time, the tabs 16 of each inner conductor 12 protrude and are disposed inside the cylindrical portion 35.
[0043] Next, the second opposing surface 45 of the second outer conductor 15 is arranged above the first opposing surface 44 of the upper protruding portion 41. Also, the first opposing surface 44 of the upper protruding portion 41 is used as a standard (reference) to move the second outer conductor 15 downward. During the installation of the second outer conductor 15, the second opposing surface 45 is made to follow the first opposing surface 44 (refer to the single-dot chain line). Thus, the position of the front end of the second outer conductor 15 can be determined. Therefore, the installation of the second outer conductor 15 to the first outer conductor 14 can be easily performed. Also, during the installation of the second outer conductor 15, the locking portion 42 comes into contact with the left and right outer surfaces of the first side wall 31, and the second side wall 43 is expanded outward in the left and right directions. Figure 6
[0044] When the second outer conductor 15 is installed to the first outer conductor 14, the opening portion 38 is covered by the covering wall 46. At this time, the crimping portion 47 is overlaid on the shielding portion 19 of the shielded electric wire 11 from above. The second side wall 43 is elastically returned, and the second outer conductor 15 is held in a state where it is inhibited from falling off with respect to the first outer conductor 14 by making the locking portion 42 engage with the locked portion 39. Then, the crimping portion 47 is crimped to the shielding portion 19 of the shielded electric wire 11. Specifically, the crimping portion 47 is arranged between a lower die and an upper die which are not shown, and the upper die which is lowered in the direction of the arrow B (refer to Figure 7 ) is pressed to the lower die, thereby being crimped in a manner of being wound around the shielding portion 19.
[0045] During the crimping of the crimping portion 47, the front end portion of the covering wall 46 is subjected to a force (refer to the arrow A of Figure 7 ) which tends to rotate in a direction of floating with respect to the first outer conductor 14 with the crimping portion 47 as a rotation axis. In particular, each lower protruding portion 40 is arranged at a lower portion of each first side wall 31, and the second opposing surface 45 is located at a position of the second outer conductor 15 which is farthest from the crimping portion 47. Therefore, the force which tends to rotate the second outer conductor 15 is greatly applied to the first opposing surface 44 which comes into contact with the second opposing surface 45. Thus, by the second opposing surface 45 of the second outer conductor 15 coming into contact with the first opposing surface 44 of the lower protruding portion 40, the second outer conductor 15 can be effectively inhibited from being misaligned in a direction of floating with respect to the first outer conductor 14. Also, since the second opposing surface 45 is a front end surface of the second side wall 43, and is not a shape which cuts the second side wall 43, the shielding performance can be maintained.
[0046] Further, since the locking portion 42 is fitted into the locked portion 39 and can be caught, displacement of the second outer conductor 15 from the first outer conductor 14 can be suppressed. However, a gap is formed between the locked portion 39 and the locking portion 42 after the locking portion 42 is fitted into the locked portion 39. Therefore, there is a possibility that the second outer conductor 15 is displaced from the first outer conductor 14 by the amount of the gap. In this regard, in the case of the present embodiment 1, the first opposing surface 44 and the second opposing surface 45 oppose each other with a gap smaller than the gap. Further, the position at which the second opposing surface 45 touches the first opposing surface 44 is close to the catching position of the locked portion 39 and the locking portion 42. As described above, by the second opposing surface 45 touching the first opposing surface 44, not only can the second outer conductor 15 be prevented from being displaced in the direction of floating with respect to the first outer conductor 14, but also the locked portion 39 and the locking portion 42 can be prevented from touching each other, so that the application of load to the catching portions of the locked portion 39 and the locking portion 42 can be prevented. In particular, in the case of the present embodiment 1, both the first opposing surface 44 and the second opposing surface 45 are vertical surfaces extending in the vertical direction. Therefore, the front end portion of the cover wall 46 can be reliably prevented from being displaced in the direction of floating with respect to the first outer conductor 14.
[0047] [Other Embodiments] It should be understood that the embodiments disclosed herein are illustrative only and not restrictive of the scope of the application. In the case of the above-described embodiment 1, the first opposing surface is the rear end surface of the lower protruding portion and the upper protruding portion. In contrast, according to another embodiment, instead of the lower protruding portion, a step can be formed in the first side wall, and the rear end surface of the step can be the first opposing surface. In the case of the above-described embodiment 1, the lower protruding portion and the upper protruding portion are formed in the same shape. In contrast, according to another embodiment, the lower protruding portion and the upper protruding portion can be formed in different shapes. In the case of the above-described embodiment 1, the protruding portion is protruded by an amount smaller than the thickness of the second side wall. In contrast, the protruding portion can be protruded by an amount larger than the thickness of the second side wall. In the case of the above-described embodiment 1, the protruding portion is formed by punching or beating processing such as louver processing. In contrast, the protruding portion can be formed by cutting out and standing up. Reference Signs
