[0028] [Description of embodiments of this disclosure]

[0029] First, embodiments of this disclosure will be described and illustrated.

[0030] The shielding terminal disclosed herein,

[0031] (1) An outer conductor connected to the shielding portion of a shielded wire, the outer conductor having a connecting member and a mounting member independent of the connecting member, the connecting member having a cylindrical portion and an extension portion extending in a direction intersecting the cylindrical portion, the mounting member having a crimping portion covering the outer surface of the extension portion and crimping it to the shielded wire through the extension portion, the extension portion and the cylindrical portion being L-shaped in side view and being continuous by an inner corner portion formed between the outer surfaces of the extension portion and the cylindrical portion respectively.

[0032] According to the above structure, since the extension and the cylindrical portion are continuous through the inner corner portion, no gap is formed at the inner corner portion, thus improving the shielding performance. Furthermore, since the mounting member has a crimping portion and the connecting member has a cylindrical portion, the forming freedom of the crimping portion and the cylindrical portion is increased compared to the case where a crimping portion and a cylindrical portion are formed on a single outer conductor.

[0033] (2) Preferably, the crimping portion has: a base that contacts the outer surface of the extension; and a tube that protrudes from the base and surrounds the shielded wire, wherein the side of the tube relative to the base and the side of the tube relative to the base are opposite to each other.

[0034] Based on the above structure, during the crimping process of the crimping part relative to the shielded wire, interference between the mold that deforms the cylinder and the cylinder part can be avoided.

[0035] (3) Preferably, the connecting member has an interfacing portion that is independent of the extension portion and is bent to be connected to the cylindrical portion and sandwiched between the shielded wire and the crimping portion. The crimping portion has a shielding portion that closes the gap formed between the extension portion and the interfacing portion.

[0036] According to the above structure, since the gap between the extension and the intermediate part is also closed by the shielding part of the mounting member, the shielding performance can be further improved.

[0037] (4) Preferably, an insulating dielectric is disposed between the outer conductor and the inner conductor, the dielectric having: an insertion portion disposed inside the cylindrical portion; and a dielectric body portion extending in a direction intersecting the insertion portion and disposed along the extension portion, the connecting member having an opposing extension portion at a position opposite to the extension portion, the opposing extension portion and the cylindrical portion forming an L-shape in side view, continuous by an outer corner portion formed between the outer surfaces of the opposing extension portion and the cylindrical portion respectively, the opposing extension portion being configured to be rotatable relative to the cylindrical portion to an open position and a closed position with the outer corner portion as the center, the inner side of the cylindrical portion being open in the open position, and the dielectric body portion being sandwiched between the extension portion and the cylindrical portion in the closed position.

[0038] According to the above structure, when the opposing extension is in the open position, the insertion part of the dielectric can be inserted into the inside of the cylindrical portion, and the dielectric body is supported on the extension. When the opposing extension is in the closed position, the dielectric body is sandwiched between the opposing extension and the extension. Furthermore, the crimping part is crimped onto the shielded wire, thereby restricting the opposing extension from shifting to the open position. At the same time, it also prevents the dielectric from detaching from the outer conductor.

[0039] [Details of the embodiments of this disclosure]

[0040] Specific examples of this disclosure are described below with reference to the accompanying drawings. Furthermore, the invention is not limited to these examples, but rather, as shown by the claims, includes all modifications within the meaning and scope equivalent to the claims.

[0041] <Implementation Method 1>

[0042] like Figure 1 As shown, the shielding terminal 10 of Embodiment 1 of this disclosure includes a conductive inner conductor 11, an insulating dielectric 12, and a conductive outer conductor 13. The dielectric 12 is disposed between the inner conductor 11 and the outer conductor 13, providing electrical insulation between the inner conductor 11 and the outer conductor 13. The shielding terminal 10 is connected to the end of a shielded wire 90. Furthermore, in the following description, regarding the front-to-back direction, [the following will be used]. Figure 1 The left side is designated as the front side. The front side is the top edge of the shielded wire 90 along its length, indicated by reference numeral F in the figure. The rear side is the opposite side of the front side, indicated by reference numeral R in the figure. Regarding the vertical direction, [the following is a partial translation of the original text, which is not translated here]. Figure 1 The upper side is designated as the upper side. The upper side is the connection side to the shielded terminal of the other party (not shown), indicated by reference numeral U in the figure. The lower side is the opposite side of the upper side, indicated by reference numeral D in the figure. These directions are determined solely for illustrative purposes and do not limit the manner of use.

[0043] <Shielded wire>

[0044] Shielded wire 90 is a coaxial cable, such as Figure 1 As shown, the shielded wire 90 includes a core wire 91, a sheath 92, a shield 93, and a sheath (outer jacket) 94. The core wire 91 is a conductor that transmits high-frequency signals. The sheath 92 is a sheath made of insulating resin that covers the outer periphery of the core wire 91. The shield 93 is a braided wire that covers the outer periphery of the sheath 92. The shield 93 can also be a structure obtained by adding metal foil such as copper foil, gold foil, or aluminum foil to the braided wire. The sheath 94 is a sheath made of insulating resin that covers the outer periphery of the shield 93. At the end of the shielded wire 90, the shield 93 is exposed by removing the sheath 94, and the core wire 91 is exposed by further removing the sheath 92. A cylindrical conductive sleeve 95 is inserted between the exposed shield 93 and the sheath 92.

[0045] <Inner conductor>

[0046] The inner conductor 11 is integrally formed by bending a metal plate, etc. For example... Figure 1 As shown, the inner conductor 11 is L-shaped in side view, with a core wire crimping portion 14 on the rear side and a parallel inner conductor connecting portion 15 extending vertically on the front side. The core wire crimping portion 14 is crimped to the core wire 91 of the shielded wire 90 for electrical connection. The parallel inner conductor connecting portion 15 contacts the parallel inner conductor of the parallel shielding terminal (not shown) for electrical connection.

[0047] <Dielectric>

[0048] Dielectric 12 is made of synthetic resin and has an L-shape when viewed from the side, such as Figure 1 and Figure 2 As shown, the device has an insertion portion 16 extending vertically and a dielectric body portion 17 extending longitudinally. The insertion portion 16 is cylindrical and houses the inner conductor 11 and its corresponding inner conductor connection portion 15 inside. The insertion portion 16 has a lower portion 71 on the lower side, an upper portion 72 on the upper side, and a stepped portion 73 between the upper portion 72 and the lower portion 71. The upper portion 72 has a smaller diameter than the lower portion 71 due to the stepped portion 73. A groove 74 extending vertically is formed on the outer peripheral surface of the lower portion 71. The upper end of the groove 74 opens at the stepped portion 73. The dielectric body portion 17 is cylindrical and houses the core wire crimping portion 14 of the inner conductor 11 inside. The front portion of the dielectric body portion 17 is connected to the rear portion of the insertion portion 16. Figure 1 As shown, the inner sides of the dielectric body portion 17 and the insertion portion 16 are interconnected, forming an inner conductor storage space S1 that is L-shaped in side cross-section.

[0049] like Figure 2As shown, the lower wall 19 of the dielectric body 17 is connected to the lower front end of the insertion part 16 via the hinge part 18, and can be opened and closed with the hinge part 18 as the center. When the lower wall 19 of the dielectric body 17 is in the open state, the lower part of the insertion part 16 is open, and the inner conductor connection part 15 can be inserted into the inside of the insertion part 16 from below.

[0050] like Figure 10 As shown, rib-shaped engaging portions 21 extending in the front-rear direction are formed in pairs at the left and right corners on the upper side of the dielectric body portion 17. An inclined beveled portion 22 is formed on the outer surface of the engaging portion 21 by chamfering the corners.

[0051] <External Conductor>

[0052] The outer conductor 13 is integrally formed by bending a metal plate, etc. For example... Figure 1 As shown, the outer conductor 13 is L-shaped in side view and has a connecting member 23 and a mounting member 24. The connecting member 23 and the mounting member 24 are separate parts and can be separated from each other.

[0053] In the closed position described later, the connecting member 23, as... Figure 8 As shown, the component has an L-shape when viewed from the side, and includes a cylindrical section 25 and a plate-shaped extension 26 and an intersecting section 27 that are connected to the cylindrical section 25 at an intersection. Furthermore, in the following description of the connecting member 23, unless otherwise specified, the references for the front-to-back and vertical directions are based on the closed position described later. Figure 8 The state shown is used as a reference.

[0054] The cylindrical portion 25 is arranged with its axis oriented vertically. The outer conductor of the opposite shielding terminal (not shown) is inserted from above into the inner side of the cylindrical portion 25.

[0055] Multiple elastic contact portions 28 are formed in the upper part 32 of the cylindrical portion 25. Figure 8 (Only one is shown in the figure). Each elastic contact portion 28 is arranged circumferentially spaced in the cylindrical portion 25. Furthermore, each elastic contact portion 28 is flexibly formed between the slits 29 on both sides of the cylindrical portion 25. Each elastic contact portion 28 has a contact portion that protrudes inwards from the cylindrical portion 25 and can contact the outer conductor of the opposing shielding terminal. Additionally, a [missing information - likely a typo, should be inserted here] is formed on the front side of the upper portion 32 of the cylindrical portion 25, below each elastic contact portion 28. Figure 1 The protrusion 75 is shown. The protrusion 75 is cut inward from a portion of the cylindrical portion 25 and has a shape that slopes backward as it moves upward. The protrusion 75 can engage with the groove 74 of the dielectric 12.

[0056] The lower part 31 of the cylindrical part 25 is as follows Figure 3 As shown, the cross-section is arc-shaped, opening at the rear from the closed position, and in the open position described later ( Figure 3 The state shown is open both at the back and the bottom. (As indicated) Figure 3 and Figure 4 As shown, a pair of left and right engaging recesses 33 are formed between the lower part 31 and the upper part 32 of the cylindrical portion 25. Each engaging recess 33 extends in the front-rear direction and opens at the rear. A pair of left and right engaging portions 34 are formed below each engaging recess 33 in the lower part 31 of the cylindrical portion 25. Each engaging portion 34 can flex and deform in the left-right direction (inside-outside direction). Each engaging portion 34 has an open end 35 at its rear end that extends in the up-down direction.

[0057] The extension 26 is formed by bending backward from the lower rear end of the upper portion 32 of the cylindrical portion 25. The extension 26 is positioned above the open end 35 of each engaging portion 34. Figure 8 As shown, the upper part 32 of the cylindrical portion 25 and the extension 26 are L-shaped in side view, and are continuously connected by the inner corner portion 36, which is the inner corner of the L. The inner corner portion 36 has an angle of α (0°<α<180°, preferably 80°<α<100°, particularly preferably α=90°) between the outer surface (upper surface) of the extension 26 and the outer surface (rear surface) of the cylindrical portion 25 in side view.

[0058] like Figure 3 As shown, the intermediate portion 27 is integrally connected to the lower end of the lower portion 31 of the cylindrical portion 25. The intermediate portion 27 has a... Figure 8 The closed position shown shows an opposing extension 37 that bends backward from the lower end of the lower portion 31. The opposing extension 37 is disposed below the extension 26 and opposite to the extension 26. The dielectric body portion 17 is disposed between the opposing extension 37 and the extension 26.

[0059] The opposing extension 37 is positioned below the open end 35 of each engaging portion 34. The opposing extension 37 and the cylindrical portion 25 are L-shaped in side view and are continuously connected by an outer corner portion 38, which is the outer corner of the L. The outer corner portion 38 is formed between the outer surface (lower surface) of the opposing extension 37 and the outer surface (front surface) of the cylindrical portion 25.

[0060] like Figure 3 and Figure 4 As shown, the interfacing portion 27 has a pair of sidewall portions 39 that bend and stand upright from the left and right ends of the front and rear middle portions of the opposing extension portion 37. Figure 8 As shown, the front ends of each sidewall portion 39 are arranged vertically in the closed position, parallel to the open ends 35 of each engaging portion 34. A gap G1 is formed between the upper ends of each sidewall portion 39 and each lateral extension 41 (described later) and the left and right side ends of the extension 26.

[0061] Additionally, the interfacing portion 27 has a pair of lateral extensions 41 extending rearward from the rear end of each sidewall portion 39. For example... Figure 3 and Figure 4 As shown, each lateral extension 41 has: a pair of inclined portions 42 that are inclined in a manner that expands rearward; and a pair of wire holding portions 43 that extend from each inclined portion 42 at intervals in the left-right direction to the rear end of the interfacing portion 27. Similarly, as Figure 8 As shown, the extension 26 and the opposing extension 37 also have: a pair of inclined portions 42 that are inclined in a manner that expands toward the rear; and a pair of wire holding portions 43 that extend from each inclined portion 42 at intervals in the vertical direction to the rear end of the interfacing portion 27.

[0062] Each wire retaining part 43 is formed with an arc-shaped cross-section and is arranged along the outer periphery of the shielding part 93 of the shielded wire 90. For example... Figure 9 As shown, an imaginary circle C1 can be formed by interconnecting the wire holding portions 43. The inner diameter of the imaginary circle C1 is changed by the bending deformation of each wire holding portion 43 through the extension portion 26, the opposing extension portion 37, and the side extension portion 41. The imaginary circle C1 shrinks in diameter during the crimping process of the crimping portion 59, which will be described later.

[0063] In addition, such as Figure 4 As shown, rectangular stop holes 44 are formed circumferentially at intervals in each wire holding portion 43. The shielding portion 93 of the shielded wire 90 can engage with and lock into each stop hole 44. A rectangular locking hole 45 is formed through the wire holding portion 43 of the opposing extension 37. The locking hole 45 is formed with a larger diameter than the stop hole 44, located behind it. Figure 6 The locking piece 56 shown can be inserted into the locking hole 45 and locked therein.

[0064] like Figure 1 As shown, the outer corner portion 38, as already described, is formed at the rotation center portion 46 connecting the intermediate portion 27 and the cylindrical portion 25. Figure 3 and Figure 4 As shown, the rotation center portion 46 is in the shape of a flexible band. The intermediate portion 27 can rotate relative to the cylindrical portion 25 to an open position with the rotation center portion 46 as the center. Figure 3 , Figure 4 as well as Figure 7 (as shown) and closed position ( Figure 1 , Figure 8 , Figures 9-11 (As shown in the diagram). In the open position, the access portion 27 is arranged in the vertical direction, and the lower parts of the cylindrical portion 25 and the extension portion 26 are each open. In the closed position, the access portion 27 is arranged in the front-back direction, and the lower parts of the cylindrical portion 25 and the extension portion 26 are each closed by the opposing extension portion 37.

[0065] Next, the mounting member 24 will be described. The mounting member 24 has a shape that extends in the front-to-back direction, such as... Figure 1 and Figure 11 As shown, it is mounted from above on the connecting member 23 in a manner that covers the outer surface of the extension 26. Figure 5 and Figure 6 As shown, the mounting component 24 has a base 47, a pair of cylinders 48, a pair of sheaths 49, and a pair of shielding parts 51.

[0066] The base 47 is a strip-shaped portion extending in the front-rear direction. A flat planar portion 52 is formed at the front of the base 47. Figure 11 As shown, a protruding tab 53 is formed in a bent and upright manner on the flat portion 52. The protruding tab 53 fits into a recess (not shown) of a housing that houses the shielding terminal 10, serving to position the shielding terminal 10 within the housing. An opening 54 is formed in the flat portion 52 due to the bent and upright nature of the protruding tab 53. The protruding tab 53 is arranged in a left-right direction and is shaped to stand upright from the front end of the opening 54. A reinforcing portion 76 is formed on the front side of the lower end of the protruding tab 53, extending from the opening 54 side.

[0067] A rear base 55 is formed at the rear of the base 47. Each cylinder 48 is a plate-like structure protruding downwards from both the left and right ends of the front portion of the rear base 55. Figure 1 As shown, each sleeve 48 clamps the wire holding part 43 in the middle and presses it against the shielding part 93 of the shielded wire 90. The shielding part 93 is electrically connected to the outer conductor 13 in a state where it is clamped between the wire holding part 43 and the sleeve 95.

[0068] Each sheath 49 is formed as a plate-like shape protruding downwards from both ends of the rear portion of the rear base 55. Each sheath 49 is crimped onto the sheath 94 of the shielded wire 90. A recess 57 and a protrusion 58 are formed at the top of each sheath 49. When each sheath 49 is connected to the sheath 94 of the shielded wire 90, each sheath 49 and the rear base 55 are formed into a cylindrical shape, and the recess 57 and the protrusion 58 engage and lock together. Furthermore, at the rear of the mounting member 24, each cylinder 48, each sheath 49, and the rear base 55 constitute the crimping portion 59 of this disclosure.

[0069] like Figure 5 As shown, each shielding portion 51 is formed as a plate-like structure protruding downwards from the left and right sides of the planar portion 52. (As shown...) Figure 11 As shown, each shielding portion 51 covers the outer surface of each side wall portion 39 and each side extension portion 41, and covers the gap G1 formed between the extension portion 26 and the interfacing portion 27 (see reference). Figure 8The shielding portion 51 is closed. The rear end of each shielding portion 51 is connected to each cylinder 48. A pair of holding pieces 61, which are rectangular in shape when viewed from the side, are formed on the front side of each shielding portion 51. Each holding piece 61 protrudes significantly downwards and further from the rear side of each shielding portion 51, closing the gap G2 (see reference) formed between the open end 35 of each engaging portion 34 and the front end of each side wall portion 39. Figure 8 and Figure 11 ) Closed.

[0070] Assembly method and function of shielding terminals

[0071] First, in the connecting member 23, the intermediate portion 27 is open relative to the cylindrical portion 25 in an open position (see reference). Figure 3 and Figure 4 In this state, the dielectric 12 is inserted into the inside of the connecting member 23 from below (actually above) as shown in the figure. During the insertion of the dielectric 12, the protrusion 75 engages with the groove 74 in a positioning state (see reference). Figure 1 Furthermore, when the insertion of the dielectric 12 is completed, the extension 26 contacts each of the engaging portions 21 on the upper surface of the dielectric body 17 in a positioning state, and the insertion of the dielectric 12 stops.

[0072] The lower wall 19 of the dielectric body 17 is opened to the open state, and the inner conductor 11 is inserted into the inner conductor storage space S1 of the dielectric body 12 from below (actually above) as shown in the figure. The inner conductor 11 is pre-connected to the end of the shielded wire 90. When the inner conductor 11 is inserted into the inside of the dielectric body 12, the outer inner conductor connection part 15 is disposed inside the insertion part 16, and the core wire crimping part 14 is disposed inside the dielectric body 17. Then, the dielectric part 27 rotates around the rotation center part 46 and closes relative to the cylindrical part 25 in the closed position (see reference). Figures 8-10 ).

[0073] With the mounting members 24 overlapping and arranged on the outside of the connecting members 23, and the crimping portion 59 of the mounting members 24 provided in a crimping mold (not shown), each cylinder 48 is pressed inward by a movable mold (not shown). Each wire holding portion 43 is also pressed inward by each cylinder 48. Thus, each cylinder 48 is crimped to the shielding portion 93 of the shielded wire 90 via each wire holding portion 43. As a result, the outer conductor 13 is electrically connected to the shielding portion 93 of the shielded wire 90 (see reference). Figure 1 and Figure 11 Additionally, the mounting member 24 is held to the connecting member 23 by each cylinder 48. Furthermore, the interfacing portion 27 is held in a closed position relative to the cylinder portion 25 by each cylinder 48.

[0074] Each sheath 49 and each cylinder 48 are crimped simultaneously or directly onto the sheath 94 of the shielded wire 90, thus mechanically connecting them. Furthermore, the movable mold (not shown) is located on one side where each cylinder 48 and each sheath 49 are located, thus easily avoiding interference with the cylinder portion 25.

[0075] With the mounting member 24 installed on the connecting member 23 as described above, the gap G1 formed between the extension 26 and the intermediate portion 27 is covered by the shielding portion 51 and the crimping portion 59, and the gap G2 formed between the cylindrical portion 25 and the intermediate portion 27 is also covered by the shielding portion 51. Furthermore, the extension 26 and the cylindrical portion 25 are continuously formed in an L-shape in side view via the inner corner portion 36, so there is no break at the position of the inner corner portion 36 (see reference). Figure 1 Therefore, according to Embodiment 1, noise leakage from the shielding terminal 10 and noise intrusion into the shielding terminal 10 can be suppressed, thereby improving shielding performance. In particular, since the crimping portion 59 is formed on the mounting member 24 and the cylindrical portion 25 is formed on the connecting member 23 which is independent of the mounting member 24, the forming freedom of the crimping portion 59 and the cylindrical portion 25 can be increased. Therefore, for example, the cylindrical portions 48 and 25 of the crimping portion 59 can be arranged close together in the front-rear direction.

[0076] <Implementation Method 2>

[0077] like Figure 12 As shown, in Embodiment 2, the shielding terminal 10A is connected to the shielding wire 90A, which has a smaller diameter than the shielding wire 90 in Embodiment 1. The shielding wire 90A does not have the structure of the sleeve 95 as in Embodiment 1. The shielding terminal 10A in Embodiment 2 differs from Embodiment 1 in that the second cylinder 62 is formed in the crimping portion 59A of the mounting member 24A, and in that each inclined portion 42 of the connecting member 23 is inclined in a way that it narrows toward each wire holding portion 43. Other aspects are the same as in Embodiment 1, so the same reference numerals are used for the same or equivalent parts as in Embodiment 1, and repeated descriptions are omitted.

[0078] The second cylinder 62 of the crimping part 59A is formed in pairs between each sheath cylinder 49 and each cylinder 48. Each second cylinder 62, like the sheath cylinder 49 and the cylinder 48, is an open cylinder and protrudes from the left and right ends of the rear base 55.

[0079] Each second cylinder 62 is directly pressed into the shielding part 93 of the shielded wire 90A and electrically connected to it, located behind the connecting member 23. The diameter of the cylinder shape of each second cylinder 62 is smaller than the diameter of the cylinder shape of each cylinder 48 and the sheath cylinder 49.

[0080] According to this embodiment 2, since each of the second cylinders 62 is directly pressed into the shielding portion 93 of the shielded wire 90A, the connection between the shielded wire 90A and the outer conductor 13 can be stably maintained.

[0081] [Other embodiments of this disclosure]

[0082] The embodiments disclosed herein should be considered illustrative in all respects, and not restrictive.

[0083] In embodiments 1 and 2, a pair of lateral extensions are formed in the connecting member. However, in other embodiments, at least one of the pair of lateral extensions may be omitted from the connecting member.

[0084] In embodiments 1 and 2, a shielding portion is formed in the connecting member. However, in other embodiments, the shielding portion may be omitted from the connecting member.

[0085] In embodiments 1 and 2, a sheath is formed on the mounting member. However, as another embodiment, the sheath may be omitted from the mounting member. For example, the sheath may also be formed on the connecting member.

[0086] In embodiments 1 and 2, the inner corner portion is a right-angled connecting tube portion and extension portion. However, in other embodiments, the inner corner portion may also be a curved connecting tube portion and extension portion.
