Title: Shielded terminal

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is based on and claims priority from Japanese Patent Application No. 2021-190337, filed on Nov. 24, 2021, with the Japan Patent Office, the disclosure of which is incorporated herein in its entirety by reference. 
     TECHNICAL FIELD 
     The present disclosure relates to a shielded terminal. 
     BACKGROUND 
     JP 2014-107140A discloses a shielded terminal that is called a connection terminal. The shielded terminal has a connection part and a terminal part, and has an L shape in a side view. The connection part has an external conductor crimp barrel part and an insulator surrounding part. The terminal part has a cylindrical terminal external conductor. The external conductor crimp barrel part, the insulator surrounding part, and the terminal external conductor constitute the outer conductor of the shielded terminal. The external conductor crimp barrel part is bent into a tubular shape when the external conductor (shield part) of a coaxial cable (shielded electrical wire) is crimped. This forms a gap at an inner corner part between the leading end of the external conductor crimp barrel part and the terminal external conductor. JP 2014-107139A, JP 9-120870A, and JP 8-153557A also disclose techniques related to shielded terminals. 
     SUMMARY 
     In the case of JP 2014-107140A, there is a concern that high-frequency signals may cause the outflow and inflow of noise through the gap at the inner corner part of the external conductor and deteriorate shielding performance. In addition, since the barrel shape of the external conductor crimp barrel part and the tubular shape of the terminal external conductor need to be formed into one external conductor, there arises a problem in which the degree of freedom in forming is limited. 
     In view of this, an object of the present disclosure is to provide a shielded terminal with which the shielding performance and the degree of freedom in forming can be increased. 
     The present disclosure relates to a shielded terminal including an outer conductor connected to a shield part of a shielded electrical wire, wherein the outer conductor includes a connection member and an attachment member that is separate from the connection member, the connection member includes a tubular part and an extension part that extends in a direction intersecting the tubular part, the attachment member includes a crimp part that is crimped to the shielded electrical wire with the extension part interposed therebetween while covering an outer surface of the extension part, and the extension part and the tubular part form an L shape in a side view, and are continuous with each other via an inner corner part formed between outer surfaces of the extension part and the tubular part. 
     According to the present disclosure, it is possible to provide a shielded terminal with which the shielding performance and the degree of freedom in forming can be increased. 
     The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.

     DETAILED DESCRIPTION 
     In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. 
     First, embodiments of the present disclosure will be listed and described. 
     (1) A shielded terminal of the present disclosure is a shielded terminal including an outer conductor connected to a shield part of a shielded electrical wire, wherein the outer conductor includes a connection member and an attachment member that is separate from the connection member, the connection member includes a tubular part and an extension part that extends in a direction intersecting the tubular part, the attachment member includes a crimp part that is crimped to the shielded electrical wire with the extension part interposed therebetween while covering an outer surface of the extension part, and the extension part and the tubular part form an L shape in a side view, and are continuous with each other via an inner corner part formed between outer surfaces of the extension part and the tubular part. 
     According to the foregoing configuration, the extension part and the tubular part are continuous with each other via the inner corner part and no gap is formed at the inner corner part, and thus it is possible to improve the shielding performance. Since the attachment member has the crimp part and the connection member has the tubular part, it is possible to improve the degree of freedom in forming of the crimp part and the tubular part in comparison to the case where the crimp part and the tubular part are formed in one external conductor. 
     (2) It is preferable that the crimp part includes a base part that is in contact with the outer surface of the extension part and a barrel that protrudes from the base part and surrounds the shielded electrical wire, and a side of the base part on which the barrel is positioned and a side of the base part on which the tubular part is positioned are opposite to each other. 
     According to the foregoing configuration, it is possible to avoid the interference between a die for deforming the barrel and the tubular part in the course of crimping of the crimp part to the shielded electrical wire. 
     (3) It is preferable that the connection member includes, separate to the extension part, an interposing part that is bent and connected to the tubular part and is sandwiched between the shielded electrical wire and the crimp part, and the crimp part includes a blocking part that closes a gap formed between the extension part and the interposing part. 
     According to the foregoing configuration, the gap between the extension part and the interposing part can also be closed by the blocking part of the attachment member, and thus the shielding performance can be further improved. 
     (4) It is preferable that an insulating dielectric body is disposed between the outer conductor and the inner conductor, the dielectric body includes an insertion part that is disposed inside the tubular part and a dielectric body part that extends in a direction intersecting the insertion part and is disposed along the extension part, the connection member includes an opposing extension part at a position opposing the extension part, the opposing extension part and the tubular part form an L shape in a side view and are continuous via an outer corner part formed between outer surfaces of the opposing extension part and the tubular part, and the opposing extension part is capable of pivoting to an open position and a closed position around the outer corner part with respect to the tubular part, the inside of the tubular part is open at the open position, and the dielectric body part is sandwiched between the opposing extension part and the extension part at the closed position. 
     According to the foregoing configuration, when the opposing extension part is at the open position, the insertion part of the dielectric body can be inserted into the tubular part and the dielectric body part can be supported by the extension part. When the opposing extension part is at the closed position, the dielectric body part is sandwiched between the opposing extension part and the extension part. Further, the crimp part is crimped to the shielded electrical wire so that displacement of the opposing extension part to the open position is regulated. At the same time, detachment of the dielectric body from the outer conductor is also regulated.

When the lower wall  19  of the dielectric body part  17  is open, the lower side of the insertion part  16  is open such that the counterpart inner conductor connection part  15  can be inserted into the insertion part  16  from below. 
     As shown in  FIG.  10   , a pair of rib-shaped engaging parts  21  extending in the front-rear direction are respectively provided at upper left and right corner parts of the dielectric body part  17 . Inclined surface parts  22  inclined by chamfering corner parts of the engaging parts  21  are formed on the outer surfaces of the engaging parts  21 , respectively. 
     Outer Conductor 
     The outer conductor  13  is integrally formed by bending one metal plate. As shown in  FIG.  1   , the outer conductor  13  has an L shape as a whole in a side view and has a connection member  23  and an attachment member  24 . The connection member  23  and the attachment member  24  are separate members that are separable from each other. 
     As shown in  FIG.  8   , the connection member  23  has an L shape in a side view at the later-described closed position, and has a cylindrical tubular part  25 , a plate piece-like extension part  26  intersecting and connected to the tubular part  25 , and an interposing part  27 . In the following description of the connection member  23 , the front-rear direction and the vertical direction are defined with reference to a state in which the connection member  23  is at the later-described closed position (the state shown in  FIG.  8   ) unless otherwise specified. 
     The tubular part  25  is disposed with the axial center thereof oriented in the vertical direction. The counterpart outer conductor of the counterpart shielded terminal (not shown) is inserted into the tubular part  25  from above. 
     An upper part  32  of the tubular part  25  is provided with a plurality of elastic contact parts  28  (only one is shown in  FIG.  8   ). The elastic contact parts  28  are arranged spaced apart from each other in a circumferential direction of the tubular part  25 . The elastic contact parts  28  are formed so as to be capable of bending and deforming between slits  29  on two sides thereof in the tubular part  25 . The elastic contact parts  28  each protrude to the inside of the tubular part  25  and have a contact point portion that is contactable with the counterpart outer conductor of the counterpart shielded terminal. A protrusion  75  shown in  FIG.  1    is formed on the front side of the upper part  32  of the tubular part  25 , below the elastic contact parts  28 . The protrusion  75  is cut and raised inward from a portion of the tubular part  25  and is inclined rearward while extending upward. The protrusion  75  can be fitted into the groove  74  of the dielectric body  12 . 
     As shown in  FIG.  3   , a lower part  31  of the tubular part  25  has an arc-shaped cross section, is open rearward at the closed position, and is open both rearward and downward at the later-described open position (the state shown in  FIG.  3   ). As shown in  FIGS.  3  and  4   , a pair of left and right engagement recessed parts  33  are formed between the lower part  31  of the tubular part  25  and the upper part  32  of the tubular part  25 . The engagement recessed parts  33  extend along the front-rear direction and are open rearward. The lower part  31  of the tubular part  25  is provided with a pair of left and right engagement parts  34 , below the engagement recessed parts  33 . The engagement parts  34  are capable of bending and deforming in the horizontal direction (inward and outward directions). The engagement parts  34  each have an open end  35  that extends along the vertical direction at the rear end thereof. 
     The extension part  26  is formed so as to be bent extending rearward from the lower rear end part of the upper part  32  of the tubular part  25 . The extension part  26  is disposed above the open ends  35  of the engagement parts  34 . As shown in  FIG.  8   , the upper part  32  of the tubular part  25  and the extension part  26  form an L shape in a side view and are continuously connected via an inner corner part  36  that is a corner part on the inner side of the L shape. The inner corner part  36  has an intersection angle in a side view α(0°&lt;α&lt;180°, preferably 80°&lt;α&lt;100°, more preferably α=90°) between the outer surface (upper surface) of the extension part  26  and the outer surface (rear surface) of the tubular part  25 . 
     As shown in  FIG.  3   , the interposing part  27  is integrally coupled to the lower end of the lower part  31  of the tubular part  25 . The interposing part  27  has an opposing extension part  37  that is bent so as extend rearward from the lower end of the lower part  31  at the closed position shown in  FIG.  8   . The opposing extension part  37  is disposed below the extension part  26  so as to oppose the extension part  26 . The dielectric body part  17  is disposed so as to be sandwiched between the opposing extension part  37  and the extension part  26 . 
     The opposing extension part  37  is disposed on the lower side relative to the open ends  35  of the engagement parts  34 . The opposing extension part  37  and the tubular part  25  form an L shape in a side view, and are continuously connected via an outer corner part  38  that is a corner part on the outer side of the L shape. The outer corner part  38  is formed between the outer surface (lower surface) of the opposing extension part  37  and the outer surface (front surface) of the tubular part  25 . 
     As shown in  FIGS.  3  and  4   , the interposing part  27  has a pair of side wall parts  39  that are bent so as to rise from left and right side edges of an intermediate part of the opposing extension part  37  in the front-rear direction. As shown in  FIG.  8   , the front ends of the side wall parts  39  are disposed along the vertical direction so as to oppose the open ends  35  of the engagement parts  34  in parallel at the closed position. A gap G 1  is formed between the upper ends of the side wall parts  39  and later-described lateral extension parts  41  and the left and right side edges of the extension part  26 . 
     The interposing part  27  also has a pair of the lateral extension parts  41  that respectively extend rearward from the rear ends of the side wall parts  39 . As shown in  FIGS.  3  and  4   , the lateral extension parts  41  include a pair of inclined parts  42  that are inclined so as to expand rearward, and a pair of electrical wire holding parts  43  that extend from the inclined part  42  to the rear end of the interposing part  27  spaced apart from each other by a certain distance in the horizontal direction. Similarly, as shown in  FIG.  8   , the extension part  26  and the opposing extension part  37  include a pair of inclined parts  42  that are inclined so as to expand rearward and a pair of electrical wire holding parts  43  that extend from the inclined parts  42  to the rear end of the interposing part  27  spaced apart from each other by a certain distance in the vertical direction. 
     The electrical wire holding parts  43  each have an arc-shaped cross section and are disposed along the outer peripheral surface of the shield part  93  of the shielded electrical wire  90 . As shown in  FIG.  9   , a virtual circle C 1  can be formed by joining the electrical wire holding parts  43 . The electrical wire holding parts  43  change the inner diameter of the virtual circle C 1  in response to bending and deforming of the extension part  26 , the opposing extension part  37 , and the lateral extension parts  41 . The virtual circle C 1  is reduced in diameter in the course of crimping of a later-described crimp part  59 . 
     As shown in  FIG.  4   , each electrical wire holding parts  43  has stopper holes  44  that have a rectangular cross section and are spaced apart in a circumferential direction while extending therethrough. The shield part  93  of the shielded electrical wire  90  can be locked by biting into the stopper holes  44 . The electrical wire holding part  43  of the opposing extension part  37  has a lock hole  45  with a rectangular cross section while extending therethrough. The lock hole  45  is formed rearward of the stopper holes  44  and has a larger opening diameter than the stopper holes  44 . Lock pieces  56  shown in  FIG.  6    can be fitted and locked to the lock hole  45 . 
     As shown in  FIG.  1   , the outer corner part  38  described above is formed at a pivot center part  46  that connects the interposing part  27  and the tubular part  25 . As shown in  FIGS.  3  and  4   , the pivot center part  46  has a flexible band shape. The interposing part  27  is capable of pivoting around the pivot center part  46  between the open position (the state shown in  FIGS.  3 ,  4 , and  7   ) and the closed position (the state shown in  FIGS.  1 ,  8 , and  9  to  11   ) with respect to the tubular part  25 . At the open position, the interposing part  27  is disposed along the vertical direction and the lower sides of the tubular part  25  and the extension part  26  are open. At the closed position, the interposing part  27  is disposed along the front-rear direction and the lower sides of the tubular part  25  and the extension part  26  are closed by the opposing extension part  37 . 
     Next, the attachment member  24  will be described. The attachment member  24  has a shape extending in the front-rear direction. As shown in  FIGS.  1  and  11   , the attachment member  24  is attached to the connection member  23  from above and is disposed so as to cover the outer surface of the extension part  26 . As shown in  FIGS.  5  and  6   , the attachment member  24  has a base part  47 , a pair of barrels  48 , a pair of sheath barrels  49 , and a pair of blocking parts  51 . 
     The base part  47  has a band plate shape extending in the front-rear direction. A flat surface part  52  is provided at the front part of the base part  47 . As shown in  FIG.  11   , the flat surface part  52  has a protruding piece part  53  formed by bending and raising a portion of the flat surface part  52 . The protruding piece part  53  is fitted into an un-shown recess of a housing that houses the shielded terminal  10 , and has the function of positioning the shielded terminal  10  in the housing. The flat surface part  52  has an opening part  54  formed by bending and raising the protruding piece part  53 . The protruding piece part  53  is disposed along the horizontal direction and shaped so as to rise from the front end of the opening part  54 . A reinforcement part  76  obtained by pushing out a portion of protruding piece part  53  from the opening part  54  side is provided on the front side of the lower end portion of the protruding piece part  53 . 
     A rearward base part  55  is formed at the rear part of the base part  47 . The barrels  48  each have a plate piece shape and respectively protrude downward from the left and right ends of the front part of the rearward base part  55 . As shown in  FIG.  1   , the barrels  48  are crimped to the shield part  93  of the shielded electrical wire  90  with the electrical wire holding parts  43  therebetween. The shield part  93  is electrically connected to the outer conductor  13  in a state of being sandwiched between the electrical wire holding parts  43  and the sleeve  95 . 
     The sheath barrels  49  each have a plate piece shape and respectively protrude downward from the left and right ends of the rear part of the rearward base part  55 . The sheath barrels  49  are crimped to the sheath  94  of the shielded electrical wire  90 . The sheath barrels  49  correspondingly have a recessed part  57  and a protruding part  58  at the leading ends thereof. In a state in which the sheath barrels  49  are connected to the sheath  94  of the shielded electrical wire  90 , the sheath barrels  49  and the rearward base part  55  form a tubular shape, and the recessed part  57  and the protruding part  58  are matched and engaged with each other. At the rear part of the attachment member  24 , the barrels  48 , the sheath barrels  49 , and the rearward base part  55  constitute the crimp part  59  in the present disclosure. 
     As shown in  FIG.  5   , the blocking parts  51  each have a plate piece shape and respectively protrude downward from the left and right side edges of the flat surface part  52 . As shown in  FIG.  11   , the blocking parts  51  cover the outer surfaces of the side wall parts  39  and the lateral extension parts  41  to close the gap G 1  (see  FIG.  8   ) formed between the extension part  26  and the interposing part  27 . The rear ends of the blocking parts  51  are coupled to the corresponding barrels  48 . A pair of embracing pieces  61  with a rectangular shape in a side view are respectively formed at the front sides of the blocking parts  51 . The embracing pieces  61  protrude downward more than the rear sides of the blocking parts  51  to close the gap G 2  (see  FIGS.  8  and  11   ) formed between the open ends  35  of the engagement parts  34  and the front ends of the side wall parts  39 . 
     Attachment Method and Operation of Shielded Terminal 
     First, in the connection member  23 , the interposing part  27  is brought to the open position with respect to the tubular part  25  (see  FIGS.  3  and  4   ). In this state, the dielectric body  12  is inserted into the connection member  23  from below in the drawings (actually, from above). In the course of inserting the dielectric body  12 , the protrusion  75  is positioned and fitted into the groove  74  (see  FIG.  1   ). Upon completion of insertion of the dielectric body  12 , the extension part  26  is positioned between the engaging parts  21  on the upper surface of the dielectric body part  17  and brought into contact therewith, and thus the operation of inserting the dielectric body  12  is stopped. 
     The lower wall  19  of the dielectric body part  17  is brought into the open state, and the inner conductor  11  is inserted into an inner conductor housing space  51  of the dielectric body  12  from below in the drawing (actually, from above). The inner conductor  11  is connected in advance to the terminal portion of the shielded electrical wire  90 . Once the inner conductor  11  has been inserted into the dielectric body  12 , the counterpart inner conductor connection part  15  is disposed inside the insertion part  16 , and the core wire crimp part  14  is disposed inside the dielectric body part  17 . Subsequently, the interposing part  27  is pivoted around the pivot center part  46  and brought to the closed position with respect to the tubular part  25  (see  FIGS.  8  to  10   ). 
     The attachment member  24  is overlaid on the outside of the connection member  23  and the crimp part  59  of the attachment member  24  is set in a crimping die (not shown). In this state, the barrels  48  are pressed and deformed inward by a movable die (not shown). The electrical wire holding parts  43  are pressed and deformed inward by the barrels  48 . Accordingly, the barrels  48  are crimped to the shield part  93  of the shielded electrical wire  90  via the electrical wire holding parts  43 . As a result, the outer conductor  13  is electrically connected to the shield part  93  of the shielded electrical wire  90  (see  FIGS.  1  and  11   ). The attachment member  24  is held to the connection member  23  by the barrels  48 . The interposing part  27  is held by the barrels  48  in the closed position with respect to the tubular part  25 . 
     Simultaneously with or before or after the crimping of the barrels  48 , the sheath barrels  49  are crimped directly to the sheath  94  of the shielded electrical wire  90  and thus mechanically connected thereto. Since the un-shown movable die is arranged on the side on which the barrels  48  and the sheath barrels  49  are positioned, it is easy to avoid interference with the tubular part  25 . 
     In the state in which the attachment member  24  is attached to the connection member  23  as described above, the gap G 1  between the extension part  26  and the interposing part  27  is covered by the blocking parts  51  and the crimp part  59 , and the gap G 2  between the tubular part  25  and the interposing part  27  is also covered by the blocking parts  51 . Since the extension part  26  and the tubular part  25  are continuous with each other in an L shape in a side view with the inner corner part  36  therebetween, no cut appears at the position of the inner corner part  36  (see  FIG.  1   ). Thus, according to the first embodiment, it is possible to suppress the leakage of noise from the shielded terminal  10  and the intrusion of noise to the shielded terminal  10 , thereby improving shielding performance. In particular, since the attachment member  24  is provided with the crimp part  59  and the connection member  23 , which is different from the attachment member  24 , is provided with the tubular part  25 , it is possible to increase the degree of freedom in forming of the crimp part  59  and the tubular part  25 . Accordingly, the barrels  48  of the crimp part  59  and the tubular part  25  can be disposed in proximity to each other in the front-rear direction, for example. 
     Second Embodiment 
     A shielded terminal  10 A in a second embodiment is connected to a shielded electrical wire  90 A that is smaller in diameter than the shielded electrical wire  90  in the first embodiment, as shown in  FIG.  12   . The shielded electrical wire  90 A does not include an equivalent to the sleeve  95  in the first embodiment. The shielded terminal  10 A in the second embodiment is different from the shielded terminal  10  in the first embodiment in that a crimp part  59 A of an attachment member  24 A is provided with second barrels  62  and the inclined parts  42  of the connection member  23  are inclined so as to be tapered toward corresponding electrical wire holding parts  43 . Otherwise, the second embodiment is the same as the first embodiment, and thus components identical or equivalent to those in the first embodiment are given identical reference signs, and redundant description thereof will be omitted. 
     A pair of the second barrels  62  of the crimp part  59 A are provided between the sheath barrels  49  and barrels  48 . The second barrels  62  form an open barrel shape similar to the sheath barrels  49  and the barrels  48 , and respectively protrude from left and right ends of the rearward base part  55 . 
     The second barrels  62  are directly crimped and electrically connected to the shield part  93  of the shielded electrical wire  90 A rearward of the connection member  23 . The diameter of the tubular shape of the second barrels  62 , more specifically, the diameter of a tubular shape formed by the second barrels  62  and the rearward base part  55  is made smaller than the diameters of tubular shapes formed by the barrels  48  and the sheath barrels  49 . 
     According to the second embodiment, since the second barrels  62  are directly crimped to the shield part  93  of the shielded electrical wire  90 A, it is possible to stably maintain the connection state between the shielded electrical wire  90 A and the outer conductor  13 .
