Description

[Technical field]

[0001] One technique revealed by this description relates to a connection module and a connector. [State of the art]

[0002] A high-frequency connector, which is to be connected to one end of a shielded cable, in which the outer circumference of a sheathed or coated wire, having a core covered by an insulating inner sheath, is covered by a stranded wire and an insulating outer sheath, is known, for example, from Japanese patent publication JP 2011-253724 A. This high-frequency connector includes a terminal of an inner conductor, which is to be connected to the core exposed by stripping or pulling back the shielded cable, an insulating dielectric for receiving the terminal of the inner conductor in a cavity provided inside, a terminal of an outer conductor for covering the dielectric from the outside, and a connector housing for receiving the terminal of the outer conductor. The shielded cable contains...The stranded wire, exposed by peeling back or removing the insulating outer sheath, is electrically connected to the inner circumferential surface of the outer conductor, and the core of the sheathed wire, which has just been pulled forward from the stranded wire and the insulating outer sheath, is inserted into the terminal of the inner conductor and electrically connected to the core. Further connectors are known from publications US 2018 / 0026402 A1, JP 2000-208214 A, US 2013 / 0164979 A1, and US 2017 / 0332525 A1. [Summary of the invention][Problem that the invention seeks to solve]

[0003] In this type of connector, depending on the structure of the outer conductor, the center of axis of the sheathed wire emerging from the inner conductor and the center of axis of the sheathed wire emerging from the stranded wire and the insulating outer sheath may not be axially aligned and may be misaligned. If the center of axis of the sheathed wire emerging from the inner conductor and the center of axis of the sheathed wire emerging from the stranded wire and the insulating outer sheath are misaligned, the sheathed wire emerging from the dielectric material containing the inner conductor may be bent sharply. If the sheathed wire is bent sharply, there is a risk of reduced communication quality due to signal reflection. Furthermore,Because the sheathed wire has to be assembled with the inner conductor and the outer conductor while it is strongly bent, assembly handling and processing become more difficult.

[0004] A technique for suppressing the deterioration of assembly handling and suppressing a reduction in communication quality is revealed in this description. [Means to solve the problem]

[0005] The technology disclosed by this description relates to a connection module with a shielded cable comprising at least one sheathed or coated wire, a conductive shielding section for covering or sheathing an outer circumference of the sheathed wire, and a covering section for covering an outer circumference of the shielding section, an inner conductor to be connected to the sheathed wire, an insulating, terminal-receiving element for receiving an end part of the sheathed wire together with the inner conductor, and an outer conductor to be fixed while electrically connected to the shielding section when the terminal-receiving element is or is received into the outer conductor, wherein an axis center or center point of a shield-side extension section is provided for pulling out or removing the outer conductor.-guiding of the sheathed wire in the shielding section relative to an axis center or center of axis of a pull-out section on the side of the inner conductor for pulling out the sheathed wire in the inner conductor is radially displaced, and a wire insertion path is formed in a part of a wall section of the connecting element, which is directed towards a side in whose direction the axis center or center of axis of the shield-side pull-out section is displaced, and a connecting or coupling section of the sheathed wire, which is arranged between the pull-out section on the side of the inner conductor and the shield-side pull-out section, can be inserted into the wire insertion path.

[0006] Furthermore, the technology disclosed by this description is directed towards a connector with the above connection module and a housing for receiving the connection module.

[0007] If, for example, the wire insertion path is not formed in the receiving element, the connecting or coupling section of the sheathed or coated wire, which is pulled out or guided from the pull-out section on the inner conductor side, is located along an inner wall surface of the receiving element and is bent very sharply towards the pull-out section on the shielding side after being pulled out of the receiving element. A signal is easily reflected due to this drastic bending, and the sheathed wire can be damaged due to bending stress in the connecting section.

[0008] However, according to the cable with a connector configured as described above, the connecting section of the sheathed wire can be gently inclined without being sharply bent, by inserting the connecting section into the wire insertion path of the receiving link. In this way, bending stress on the connecting section of the sheathed wire can be suppressed, and a reduction in communication quality caused by signal reflection due to bending of the sheathed wire can be suppressed. Furthermore, since the connecting section of the sheathed wire can be routed while slightly inclined, the deterioration in assembly handling and workability can be suppressed compared to the case where the sheathed wire is assembled with the inner and outer conductors while sharply bent.

[0009] The connection module revealed by this description can be configured as follows.

[0010] A covering link for covering an outer circumference of the connecting section can be mounted on the connecting section of the sheathed wire, and the connecting section covered by the covering link can be inserted into the wire insertion path.

[0011] According to this configuration, it is made difficult for the connecting section to bend by mounting or arranging the covering element on the connecting or coupling section.

[0012] According to this configuration, since the connecting section, which is covered by the covering element, can be inserted into the wire insertion path, bending stress or strain on the connecting section can be suppressed, and a reduction in communication quality caused by signal reflection due to bending of the sheathed wire can be suppressed by inserting the connecting section into the wire insertion path.

[0013] The connecting member can include a first member having a first wall section, wherein the inner conductor and an end part of the sheathed wire are arranged on the first wall section, and a second member having a second wall section for covering the inner conductor and the end part of the sheathed wire from one side opposite the first wall section of the first member, and the wire insertion path can be configured by specifying or adjusting that one of the first and second wall sections is shorter in an extending direction of the sheathed wire than the other.

[0014] For example, if one of the first wall sections of the first link and the second wall section of the second link are cut to form a wire insertion path, the rigidity of the wall section formed by the wire insertion path is reduced. Therefore, there are concerns that the link or element formed by the wire insertion path may be damaged due to contact with another link when the first and second links are assembled with the inner conductor and the sheathed wire.

[0015] However, according to this configuration, since the wire insertion path is formed by setting or specifying that one of the first wall section of the first member and the second wall section of the second member is shorter than the other, the wire insertion path can be formed while suppressing a reduction in the rigidity or stiffness of the first and second members. [Effect of the invention]

[0016] According to the technique revealed by this description, it is possible to suppress the deterioration of assembly handling and to suppress a reduction in communication quality.

[Embodiments of the invention]<Ausführungsform>

[0017] An embodiment of the technology disclosed in this description is described with reference to Fig. 1 to 22 described.

[0018] A connector 10 for communication, to be installed in a vehicle, such as an electric vehicle or hybrid vehicle, and arranged in a wired communication path, for example between an electrical component in the vehicle (vehicle navigation system, ETC, monitor or the like) in the vehicle and an external device (camera or the like) or between electrical components in the vehicle, is illustrated in this embodiment.

[0019] As this is in Fig. As shown in Figures 1 to 4, the connector 10 includes a shielded cable 11, a plurality of inner conductors 20 which are to be connected to a front end of the shielded cable 11, a connection receiving element or connection receiving element 30 for receiving the plurality of inner conductors 20, an outer conductor 50 which is to be connected to the shielded cable 11 while covering the outer circumference of the connection receiving element 30, and a housing 70 for receiving the outer conductor 50.

[0020] The shielded cable 11 comprises a plurality of coated or sheathed wires 12, a shielding section 15, which is formed by a stranded wire for covering the outer circumferences of the plurality of sheathed wires 12, and a covering or sheathing section 16, which is formed by an insulating coating or sheathing for covering the outer circumference of the shielding section 15. In the shielded cable 11 of this embodiment, two sheathed wires 12 are covered jointly by the shielding section 15.

[0021] Each sheathed wire 12 is configured such that a conductive core 13 is covered by an insulating coating or sheath 14. The two sheathed wires 12 are twisted together in a state covered by the shielding section 15, and the sheathing section 16 is removed at a front end of the shielded cable 11 to expose the untwisted two sheathed wires 12 and the shielding section 15.

[0022] The shielding section 15 is formed by braiding a plurality of conductive thin metal wires into a tube. The shielding section 15, which is exposed at one end of the sheathing section 16, is folded onto an end part of the sheathing section 16 to cover the outer circumference of the end part of the sheathing section 16, and this folded part of the shielding section 15 serves as a folded section 15A. As shown in Fig. As shown in Figures 3 and 15 to 18, the two sheathed wires 12 are pulled forward from or out of the folded section 15A and a part of the folded section 15A, where the sheathed wires 12 are pulled out, serves as a shield-side extension section 19 or extension section on the shielding side.

[0023] A front end portion of each sheathed wire 12, which is pulled forward from the folded section 15A, has the insulating coating 14 further removed or stripped to expose the core 13, and the inner conductor 20 is or is electrically connected to the exposed core 13.

[0024] The inner conductor 20 is formed by processing a conductive metallic sheet material using a press or similar device. The inner conductor 20 includes a connecting tube section 22 in the form of a rectangular or right-angled tube, into which a pin-like connector (not illustrated) is inserted for connection. A wire connection section 24, which is to be crimped onto and thus connected to the ends of the core 13 and the insulating coating 14, is formed behind and continuously connected to the connecting tube section 22. Furthermore, a portion crimped onto the insulating coating 14 at a rear end of the wire connection section 24 serves as a pull-out section 25 on the side of the inner conductor, from which the sheathed wire 12 is pulled out backwards.

[0025] A part of the sheathed wire 12, which is arranged between the extension section 25 on the side of the inner conductor and the extension section 19 on the side of the shield, serves as a connecting or coupling section 17, and an adjusting element 80 for adjusting an impedance in the connecting section 17 is or will be mounted on the connecting section 17.

[0026] The adjusting element 80 is formed by processing a conductive metal sheet material using a press or the like. The adjusting element 80 comprises two adjusting bodies 82, each of which is to be mounted on the outer circumferences of the connecting sections 17 in the sheathed wires 12, and a coupling section 85, which couples the two adjusting bodies 82.

[0027] Each adjusting body 82 is formed in a substantially hollow cylindrical shape for covering the outer circumferential surface of the connecting section 17 in a circumferential direction. The adjusting body 82 is mounted in a substantially central part of the connecting section 17 in a forward-backward direction, and the length in the forward-backward direction of the adjusting body 82 is slightly shorter than that of the connecting section 17.

[0028] The coupling section 85 is curved to arch upwards and couples the two adjusting bodies 82 in a lateral direction. Furthermore, as shown in Fig. As shown in Figures 16 to 18, the coupling section 85 is designed to be laterally wider in its anterior portion than in its posterior portion. Similarly, the adjusting element 80 is laterally wider in its anterior portion than in its posterior portion.

[0029] The connecting element 30 is made of a synthetic or artificial resin and, as is shown in Fig. Figures 4 to 11 show the shape of a rectangular or right-angled parallelepiped, which is long in the forward-backward direction.

[0030] Cavities 32, extending in the forward-backward direction, are formed side by side in the lateral direction on one side of the receiving member 30 in front of a central or middle part in the forward-backward direction. As shown in Fig. 3 and Fig. As shown in Figure 22, the inner conductors 20, which are connected to the sheathed wires 12, can be placed in the respective cavities 32.

[0031] A rear part of the connecting element 30 serves as a large receiving or receiving section 33 for receiving the connecting sections 17, which are pulled out or guided backwards from the extension sections 25 on the side of the inner conductor of the two inner conductors 20, together with the adjusting element 80.

[0032] Furthermore, as this is shown in Fig. Figures 4 to 8 show that the connecting element 30 is configured by assembling a lower element or element 35, which is to be arranged in a lower part, and an upper element or element 40, which is to be arranged in an upper part, in a vertical direction.

[0033] As this is in Fig. As shown in Figures 4 to 8 and 11, the lower member 35 comprises a bottom wall 35D, which forms a bottom wall 31D of a wall section 31 of the member 30 receiving the connection, and a pair of locking pieces 36, which are provided on both side edges of the bottom wall 35D. The bottom wall 35D is in the form of a substantially rectangular plate, which is long in the forward-backward direction, and the two inner conductors 20 are arranged side by side in the lateral direction on the bottom wall 35D.

[0034] The pair of locking pieces 36 is configured to extend upwards from a rear end portion of the bottom wall 35D, and each locking piece 36 includes a substantially rectangular locking or locking hole 36A passing through it in the lateral direction.

[0035] As this is in Fig. As shown in Figures 4 to 10, the upper member 40 includes a ceiling wall 40U, which represents or forms an upper wall 31U of the member 30 receiving the connection, a front wall 42, which is provided on a front end part of the ceiling wall 40U, and side walls 44, which are provided on both lateral side edges of the ceiling wall 40U.

[0036] The ceiling wall 40U is in the form of a substantially rectangular or right-angled flat plate, which is long in the forward-backward direction, and is dimensioned to cover the inner conductors 20 and the end parts of the sheathed wires 12 from one side opposite the bottom wall 35D of the lower member 35. A partition wall 45, extending downwards from the ceiling wall 40U, is formed in a substantially central part in the lateral direction of the ceiling wall 40U. The partition wall 45 is arranged to be adjacent to the bottom wall 35D of the lower member 35 and is oriented perpendicular to it, and two cavities 32 for receiving the inner conductors 20 are formed or configured in the connection-receiving member 30 when the upper member 40 and the lower member 35 are assembled.

[0037] The front wall 42 is in the form of a plate which extends downwards from the front end edge of the ceiling wall 40U and is provided with insertion openings 42A into which the plug connections are or will be inserted.

[0038] The pair of side walls 44 each extends downwards from the ceiling wall 40U and is connected to both lateral side edges of the front wall 42.

[0039] A fitting recess 44, into which the locking element 36 of the lower member 35 is fitted when the upper member 40 and the lower member 35 are assembled, is formed in a substantially central part in the forward-backward direction of each side wall 44. The fitting recess 44A is cut vertically from a lower end portion of the side wall 44 to the top wall 40U, and a locking projection 46, which projects outwards, is formed on a side edge of the top wall 40U that faces the fitting recess 44A.

[0040] The locking projections or extensions 46 are fitted into the locking holes 36A of the locking pieces 36 to hold the upper link 40 and the lower link 35 in an assembled state, as shown in Fig. 17 and Fig. Figure 18 shows when the upper link 40 and the lower link 35 are assembled and the locking pieces 36 of the lower link 35 are fitted into the fitting recesses 44A.

[0041] As this is in Fig. As shown in Figures 20 to 22, the outer conductor 50 consists of a first outer conductor 51 for covering the outer perimeter of the connecting element 30 and a second outer conductor 60, which is to be assembled with the first outer conductor 51 to cover the outer perimeters of the first outer conductor 51 and the folded section 15A of the shielded cable 11.

[0042] The first outer conductor 51 is formed by processing a conductive metal sheet material using a press or similar device. How this is done in Fig. 3 and Fig. As shown in Figure 22, the first outer conductor 51 includes a tubular section 52 for receiving the connection receiving element 30 and a shielding connection section 53, which is provided on the rear end edge of the tubular section 52.

[0043] As this is in Fig. As shown in Figures 12 to 14, the tubular section 52 is in the form of a rectangular or right-angled tube, which has a substantially rectangular or right-angled shape or form in a front view, and the connecting element 30 is or is inserted into the tubular section 52 from the rear and received therein.

[0044] The section connecting the shielding or shielding connection section 53 includes a connecting or coupling piece 54, which extends obliquely to a lower rear side from the rear end edge of a lower side of the tubular section 52, and a tongue piece 55, which extends straight rearward from the rear end edge of the connecting piece 54.

[0045] The tongue piece 55 is in the form of a substantially rectangular or right-angled plate. When the connecting element 30 is inserted into the tubular section 52, the tongue piece 55 is or will be arranged below the folded section 15A in the shielded cable 11, as shown in Fig. 3 and Fig. 22 is shown.

[0046] The second outer conductor 60 is formed by processing a conductive metal sheet material using a press or the like. As this is described in Fig. As shown in Figures 19 to 22, the second outer conductor 60 includes a ceiling plate 61, which extends from the tubular section 52 to the position of the folded section 15A of the shielded cable 11, a pair of fixing or securing drums 62, which are provided on a front part of the ceiling plate 61, and a pair of connecting drums 63, which are provided on a rear part of the ceiling plate 61.

[0047] The ceiling plate 61 is dimensioned to cover a region from a rear part of the tubular section 52 to the folded section 15A from above, and a lance hole 61A, which passes through in the vertical direction, is provided in the front part of the ceiling plate 61.

[0048] The pair of fixing drums 62 is provided on both lateral side edge edges in the front part of the ceiling plate 61, and is crimped onto the rear part of the tubular section 52 in such a way as to wind or wrap around the tubular section 52 from both lateral sides.

[0049] The pair of connecting drums 63 is provided on the two lateral side edges in the rear part of the ceiling plate 61 in such a way as to be connected or attached behind the pair of fixing drums 62.

[0050] One of the pair of connecting drums 63 includes a side plate 64, which is to be arranged along a lateral side part of the folded section 15A, and a fixing or fastening piece 65, which is provided on the upper end of the shielding section 64, and the other includes a shielding section 64, which is to be arranged along the other lateral side part in the folded section 15A, and two fixing pieces 65, which are provided on the upper end of the shielding section 64.

[0051] As this is in Fig. 3 and Fig. As shown in Figure 22, the respective fixing pieces 65 are crimped and fixed in order to wind around the tongue piece 55 of the first outer conductor 51, which is arranged below the folded section 15A, and a lower part of the folded section 15A.

[0052] Furthermore, when the respective fixing pieces 65 are crimped onto and fixed to the folded section 15A and the tongue piece 55, the folded section 15A is pulled towards the tongue piece 55, which is arranged below it, and the tongue piece 55 extends along the lower outer circumferential surface of the folded section 15A, and an axis center β of the shield-side extension section 19 is displaced radially downwards relative to the axis centers α of the extension sections 25 on the inner conductor side in the inner conductors 20, as shown in Fig. 3 and Fig. 22 is shown.

[0053] Furthermore, a tip part of each fixing piece 65 is folded inwards to form a hook section 66.

[0054] The hook section 66 is hooked onto one of the two lateral edges of the tongue piece 55 to secure the fixing piece 65, so that the fixing piece 65 is not detached or separated from the shielding section 15 when each fixing piece 65 is crimped. In this way, the outer conductor 50, which consists of the first outer conductor 51 and the second outer conductor 60, is electrically connected to and fixed to the shielding section 15 of the shielded cable 11.

[0055] The housing 70 is made of a synthetic or artificial resin and includes a module-receiving section 72 for receiving a connection module 68, which is formed by mounting the inner conductors 20, the connection-receiving element 30 and the outer conductor 50 on the end of the shielded cable 11, as shown in Fig. 3 is shown.

[0056] The module-accommodating section 72 is in the form of a rectangular or right-angled tube, which is hollow in the forward-backward direction, and a locking lance 73, which can be locked onto an edge portion of the lance hole 61A in the outer conductor 50 of the connection module 68, is provided in the module-accommodating section 72. The locking lance 73 is fitted into the lance hole 61A, and the connection module 68 is held in the housing 70 by the locking of the locking lance 73 and the edge portion of the lance hole 61A, as shown in Fig. Figure 3 shows when the connection module 68 is mounted at a suitable or corresponding mounting position of the section 72 that receives the module.

[0057] A wire insertion path 34, into which the connecting or coupling sections 17 of the sheathed wires 12 can be inserted, is formed in the lower wall 31D (wall section 31 on a lower side in the direction towards which the center of axis β of the shield-side extension section 19 is shifted relative to the centers of axis α of the extension sections 25 on the side of the inner conductor) of the wall section 31, which represents or forms the connection-receiving element 30, as shown in Fig. 3 and Fig. 22 is shown.

[0058] As this is in Fig. 3, Fig. 17, Fig. 18 and Fig. As shown in Figure 22, the wire insertion path 34 is represented or formed by a rear end edge part 31D1 of the lower wall 31D and upper end edge parts 31W1 in rear parts of the side walls 31W, which are arranged on both lateral sides, by adjusting the lower wall 31D to be shorter in the forward-backward direction than the upper wall 31U in the rear part of the connector receiving member 30, and the large receiving or receiving section 33 is open downwards due to the wire insertion path 34.

[0059] In other words, the bottom wall 35D of the lower member 35 is designed to be shorter in the forward-backward direction than the top wall 40U of the upper member 40. When the lower member 35 and the upper member 40 are assembled, the wire insertion path 34 is formed by the rear end edge portion 35D1 in the bottom wall 35D of the lower member 35 and the lower end edge portions 44B in the side walls 44 on the two lateral sides of the upper member 40.

[0060] Furthermore, a width L1 in the lateral direction of the wire insertion path 34 is set or fixed to be greater than a width L2 in the lateral direction of the adjusting link 80, so that the connecting sections 17, which have the adjusting link 80 mounted on them, can be inserted into the wire insertion path 34.

[0061] Accordingly, as stated in Fig. 3 and Fig. 22 shows the connecting sections 17 of the sheathed wires 12, which extend obliquely while being slightly inclined towards the shield-side extension section 19, which is arranged on an oblique lower rear side of the extension sections 25 on the side of the inner conductor, laid in the wire insertion path 34, with the adjusting element 80 mounted thereon.

[0062] The embodiment is configured as described above. Next, an example assembly procedure for connector 10 for communication is briefly described, followed by a description of the functions and effects of connector 10.

[0063] First, the sheath section 16 of the shielded cable 11 is stripped or removed to expose the ends of the two sheathed wires 12 and the shield section 15, and the shield section 15 is folded onto the outer surface of the sheath section 16 to form the shield section 15A. Furthermore, the insulating coatings or sheaths 14 of the front end parts of the two sheathed wires 12 are removed to expose the cores 13, and, as shown in Fig. As shown in Figure 15, the inner conductors 20 are connected or attached to the exposed cores 13 by crimping the wire connection sections 24.

[0064] The adjusting element 80 is then mounted on the connecting sections 17 of the two sheathed wires 12 of the shielded cable 11. In a disassembled or unassembled state, before being mounted on the connecting sections 17, the upper parts, which constitute the adjusting bodies 82, are open at the top, as shown in Fig. As shown in Figure 4, the connecting or coupling sections 17 of the sheathed wires 12 are arranged on the adjusting link 80 with the open adjusting bodies 82, and the adjusting bodies 82 are crimped to wind or wrap around the connecting sections 17, thereby fixing the adjusting link 80 to the connecting sections 17.

[0065] The following explains how this is done in Fig. As shown in Figure 16, the two inner conductors 20 are mounted or arranged on the ceiling wall 40U of the vertically inverted upper member 40, and the lower member 35 is assembled with the upper member 40 from above. In this way, the inner conductors 20 are received into the member 30 receiving the connection, as shown in Figure 16. Fig. 17 and Fig. 18 is shown.

[0066] Here, when the lower link 35 is assembled with the upper link 40, the wire insertion path 34 is formed by the rear end edge part 35D1 in the bottom wall 35D of the lower link 35 and the lower end edge parts 44B in the side walls 44 on the two lateral sides of the upper link 40, since the bottom wall 35D of the lower link 35 is designed to be shorter in the forward-backward direction than the top wall 40U of the upper link 40. In this way, as shown in Fig. 17 and Fig. As shown in Figure 18, the large receiving section 33 of the connecting element 30 is open at the top and the connecting sections 17, which have the adjusting element 80 mounted on it, are exposed through the wire insertion path 34.

[0067] The following explains how this is done in Fig. Figure 19 shows that the connecting element 30 is inserted into the tubular section 52 in the first outer conductor 51 of the outer conductor 50 from the rear and the second outer conductor 60 is assembled with the first outer conductor 51.

[0068] The second outer conductor 60 is assembled by mounting the cover plate 61 of the second outer conductor 60 onto the first outer conductor 51 from above, such that the tongue piece 55 of the first outer conductor 51 is located on a lower side, and the fixing drums 62 are crimped to wrap around the tubular section 52. Furthermore, the respective fixing pieces 65 of the connecting drums 63 are crimped to wrap around the tongue piece 55 and the shielding section 15.

[0069] When the respective fixing pieces 65 are crimped, the folded section 15A is pulled towards the tongue piece 55, which is located on the lower side, and it extends as shown in Fig. 22 shows the outer circumferential surface of the lower side of the folded section 15A along the tongue piece 55 and the axis center β of the shield-side extension section 19 is radially downwards relative to the axis centers α of the extension sections 25 on the inner conductor side in the inner conductors 20.

[0070] Then the connecting sections 17 of the sheathed wires 12, which extend from the pull-out sections 25 on the side of the inner conductor towards the shield-side pull-out section 19, are inserted obliquely downwards into a wire insertion section while being slightly inclined.

[0071] Furthermore, once the respective fixing pieces 65 are crimped, the hook sections 66 of the fixing pieces 65 are hooked onto the side edges of the tongue piece 55, as shown in Fig. Figures 20 to 22 show that the fixing pieces 65 are fixed in order not to be detached or removed from the tongue piece 55 and the shielding section 15, and the connection module 68, in which the inner conductors 20, the connection receiving element 30 and the outer conductor 50 are mounted on the end of the shielded cable 11, is completed.

[0072] Finally, the connection module 68 is inserted from the rear into the module-receiving section 72 of the housing 70. When the connection module 68 reaches the appropriate or suitable receiving position, the locking lance 73 is fitted into the lance hole 61A of the outer conductor 50, and the connection module 68 is retained and held in the housing 70, as shown in Fig. Figure 3 shows that connector 10 is now ready for communication.

[0073] Next, the functions and effects of connector 10 for communication will be described.

[0074] If the axis centers α of the extension sections 25 on the inner conductor side of the inner conductors 20 and the axis center β of the extension section 19 on the shielding side cannot be aligned coaxially and are radially misaligned as in this embodiment, there is concern that the connecting or coupling sections 17 of the sheathed wires 12, which are routed between the extension sections 25 on the inner conductor side and the extension section 19 on the shielding side, will be or become severely bent, and signals in the sheathed wires 12 will be easily reflected due to the sharply bent connecting sections 17. Furthermore, the sheathed wires 12 can be damaged by bending stresses or loads that are generated or produced in the connecting sections 17.

[0075] Accordingly, the present inventors carefully investigated the above problem and, as a result, arrived at the configuration of this embodiment. That is, in the connector 10 for communication of this embodiment, the connection module 68 includes the shielded cable 11, which has at least one sheathed wire 12, the conductive shielding section 15 for covering the outer circumferences of the sheathed wires 12, and the sheathing section 16 for covering the outer circumference of the shielding section 15, the inner conductors 20, which are to be connected to the sheathed wires 12, the insulating, terminal-receiving element 30 for receiving the inner conductors 20 and the end parts of the sheathed wires 12, and the outer conductor 50, which is to be fixed while electrically connected to the shielding section 15 when...Since the connection-receiving element 30 is received in the outer conductor 15, the center of axis β of the shield-side extension section 19 for pulling out or guiding the sheathed wires 12 in the shielding section 15 is radially displaced relative to the centers of axis α of the extension sections 25 on the inner conductor side for pulling out the sheathed wires 12 in the inner conductors 20, and the wire insertion path 34, into which the connecting sections 17 of the sheathed wires 12 can be inserted between the extension sections 25 on the inner conductor side and the shield-side extension section 19, is formed in the wall section (of the lower wall 31D) 31 on the lower side of the wall section 31 of the connection-receiving element 30, in the direction of which the center of axis β of the shield-side extension section It has been postponed to 19.

[0076] That is, it is possible, as this is in Fig. 3 and Fig. As shown in Figure 22, the connecting sections 17 of the sheathed wires 12 are laid while slightly inclined, without being sharply bent, by inserting the connecting sections 17 into the wire insertion path 34 of the connector 30. In this way, bending stresses on the connecting sections 17 of the sheathed wires 12 can be suppressed, and a reduction in communication quality caused by signal reflection due to bending of the sheathed wires 12 can be suppressed. Furthermore, since the connecting sections 17 of the sheathed wires 12 can be laid while slightly inclined, the deterioration in assembly handling or workability can be suppressed, for example, compared to the case where sheathed wires with inner conductors and an outer conductor are assembled with strongly bent connecting sections.become.

[0077] Furthermore, the adjusting element (covering element) 80 is or will be mounted on the connecting sections 17 of the sheathed wires 12 to cover the outer circumferences of the connecting sections 17, and the wire insertion path 34 is dimensioned to have a width L1 such that the connecting sections 17, which are covered by the adjusting element 80, can be inserted into the wire insertion path 34.

[0078] In this embodiment, the connecting sections 17 cannot be bent when the adjusting element 80 is mounted or arranged on the connecting sections 17. Since the wire insertion path 34 of this embodiment is designed such that the connecting sections 17, which are covered by the adjusting element 80, can be inserted into it, the connecting sections 17 can be inserted into the wire insertion path 34, bending stresses on the connecting sections 17 can be suppressed, and a reduction in communication quality caused by signal reflection due to bending of the sheathed wires 12 can be suppressed.

[0079] Furthermore, it includes how this is in Fig. As shown in Figures 4 to 8, the connecting element 30 is the lower element (first element) 35, which has the bottom wall 35D (first wall section) on which the inner conductors 20 and the end parts of the sheathed wires 12 are arranged, and the upper element (second element) 40, which has the top wall 40U (second wall section) for covering the inner conductors 20 and the end parts of the sheathed wires 12 from the side opposite the lower element 35, and the wire insertion path 34 is formed by specifying that one of the bottom wall 35D and the top wall 40U is shorter in the forward-backward direction, which is an extending direction of the sheathed wires 12, than the other.

[0080] For example, if a bottom wall of a lower member and a top wall of an upper member are cut to form a wire insertion path, the rigidity or stiffness of the wall section formed with the wire insertion path is reduced, and the member formed with the wire insertion path may break, for example, due to contact with another member when the lower member and the upper member are assembled relative to an inner conductor and a sheathed wire.

[0081] However, according to this embodiment, since the wire insertion path 34 is formed by setting or defining one of the bottom wall 35D and the ceiling wall 40U to be shorter in the forward-backward direction than the other, the wire insertion path 34 can be formed while preventing a reduction in the rigidity of the lower member 35 and the upper member 40. <Andere Ausführungsformen>

[0082] The technology disclosed in this description is not limited to the embodiment described and illustrated above and includes, for example, the following different types. (1) In the above embodiment, the adjusting element 80 is mounted on the connecting or coupling sections 17. However, without limitation, no adjusting element may be mounted on the connecting section(s) if impedance adjustment is not necessary. (2) In the above embodiment, the wire insertion path 34 is formed by making the bottom wall 35D of the lower member 35 shorter in the forward-backward direction than the top wall 40U of the upper member 40. However, without limitation, the rigidity of a lower member and an upper member can be increased, and the bottom wall of the lower member can be cut to form a wire insertion path. (3) In the above embodiment, the inner conductors 20, which are represented or formed by receiving or socket terminals, are received into the receiving element 30, which consists of the lower element 35 and the upper element 40. However, without being limited to how this is done in Fig. 23 and Fig.As shown in Figure 24, inner conductors 120, which are represented or formed by connectors or plug connections, are received into a connector 130, which consists of a lower connector 135 and an upper connector 140.
