Description

[TECHNICAL FIELD]

[0001] The technology disclosed herein relates to a connection module comprising an electrical wire with a terminal and a connector. [STATE OF THE ART]

[0002] For example, a shielded connector described in JP 2013-229255A was known as a shielded connector that is connected to one end of a shielded electrical wire. The shielded electrical wire comprises shielded wires obtained by covering or sheathing inner conductive elements with insulating protective covers or sheaths, and the outer circumferences of the shielded wires are further covered or sheathed with a shielding foil and a covering. The connector terminals are electrically connected to the ends of the inner conductive elements of the shielded wires.

[0003] EP 3 496 213 A1 describes an electrically conductive part for ensuring an matching of the electrical impedance when connecting connectors to a cable comprising at least one pair of twisted electrical wires, with a front part whose shape has a continuous outer profile and which defines at least two recesses inside, each suitable for receiving the unstripped part of a cable wire, and a rear part extending from the front part, whose shape has a discontinuous outer profile bounded by ribs whose shape is complementary to that of the unstripped part of the wire of a cable. [SUMMARY OF THE INVENTION][Problem to be solved by the invention]

[0004] The shielding foil and sheathing must be removed from the end of the shielded electrical wire to electrically connect the terminals to the respective ends of the shielded wires in this type of connector. This creates a section that is not covered or sheathed by the shielding foil at the end of the shielded electrical wire, and the impedance at this unsheathed section changes from the impedance at the section covered or sheathed by the shielding foil. At this point of impedance change, signals can be reflected, and communication quality can be reduced or weakened.

[0005] The description reveals the technology for suppressing a decrease or reduction in communication quality. [Means to solve the problem]

[0006] The technical problem underlying the invention is solved by a connection module comprising an electrical wire with a terminal and a connector with the features of the independent claims. Further embodiments are defined in the dependent claims.

[0007] A technology described herein is a connection module comprising an electrical wire with a terminal, which includes a shielded electrical wire and a terminal. The shielded electrical wire includes a covered or sheathed wire, which contains a core wire through which a signal for communication is transmitted, and an insulating cover which has insulating properties and covers or sheaths the core wire, a shielding section which has electrically conductive properties and covers or sheaths an outer circumference of the covered wire, and a sheath or casing which covers an outer circumference of the shielded section. The terminal is or is connected to the sheathed wire.The sheathed wire has an end section close to the terminal, and this end section is an unsheathed section that is not covered or sheathed by the sheathing and the shielding section. The unsheathed section is or will be covered by an impedance matching element that has electrically conductive properties.

[0008] According to the connection module comprising an electrical wire with a terminal having such a configuration, the unshielded or uncovered section of the shielded or covered wire is covered or sheathed by the impedance adjusting element, which has electrically conductive properties. The unshielded section of the shielded wire that protrudes from and is exposed to the shielding section is sheathed by the electrically conductive element, and the electrically conductive element extends to cover or sheath the unshielded section of the shielded wire that protrudes from the shielding section immediately before the end section to be connected to the terminal.With this configuration, the impedance is less likely to change between the sheathed wire, which is enclosed by the shielding section, and the unsheathed section. This prevents a reduction or decrease in the communication quality of the sheathed wire.

[0009] The sheathed wire of the shielded electrical wire includes sheathed wires, each of which has the unsheathed section, and the impedance adjusting element includes adjusting body sections which have a tubular shape or form and are mounted on and along an outer circumferential surface of the unsheathed section of each of the sheathed wires.

[0010] In such a configuration, since the unshielded sections of the sheathed wires protruding from the shielding section are each independently covered or sheathed by the adjustment element sections, each adjustment element section can independently suppress any change in the impedance of the corresponding unshielded section of the sheathed wires. Therefore, the impedance is even less likely to change at the unshielded section compared to a configuration in which the unshielded sections of the sheathed wires are sheathed or covered together with an impedance adjustment element.

[0011] The adjustment body sections can each contain slots that extend in a circumferential direction.

[0012] With this configuration, the area of ​​the adjustment body section covering the unshielded section can be easily changed by altering the size of the slot. Therefore, the impedance in the unshielded section can be easily adjusted, and the accuracy of impedance adjustment in this section can be improved. This further suppresses signal reflection between the shielded wire (which is sheathed or covered by the shielding section of the shielded electrical wire) and the unshielded section, thus minimizing any reduction in communication quality.

[0013] The impedance adjustment element also includes a connecting section that links the adjustment body sections.

[0014] Since the adjustment body sections are connected or connected through the connecting section, the number of components contained in the impedance adjustment element is reduced compared to a configuration which includes adjustment body sections, each of which is or will be prepared separately for each of the unjacketed sections.

[0015] The connection module further includes a connection receiving element or connection housing element in which the connections are arranged. The connection section connects the adjustment body sections such that the distance between the sheathed wires is essentially equal to the distance between the connections in the connection receiving element. The configuration in which the distances are essentially equal includes a configuration in which the distance between the sheathed wires is the same as the distance between the connections, a configuration in which the distance between the sheathed wires is not exactly the same as the distance between the connections, and a configuration in which the distances are slightly different.

[0016] According to the connection module, which has such a configuration, the connecting section of the impedance adjusting element can adjust the distance between the sheathed wires to match the distance between the terminals in the receiving element or terminal housing element. This improves the ease of mounting the terminals in the receiving element compared to a configuration in which each terminal is positioned and mounted in each of the mounting positions in the receiving element.

[0017] The terminal receiving element includes a section receiving an adjustment element, in which the impedance adjustment element is located. The terminal receiving element includes a position error detection section between a section in which the terminals are located and the adjustment element receiving section. The position error detection section is, or becomes, contacted with the impedance adjustment element if the impedance adjustment element is not mounted in a correct position relative to the unshielded section.

[0018] For example, if the impedance adjuster is mounted in an incorrect position relative to the unshielded sections of the sheathed wires, the impedance cannot be effectively adjusted in these sections, and communication quality may be reduced. If the impedance adjuster is mounted closer to the terminals, the terminals may come into contact with the adjuster, potentially causing a short circuit.

[0019] However, according to such a configuration, if the impedance adjuster is mounted in an incorrect position and closer to the front face relative to the unshielded sections, the following problems can occur. The adjusting body sections of the impedance adjuster can contact the position error detection section if the impedance adjuster is mounted in the adjustment receiving element or the adjustment housing element. Therefore, the impedance adjuster, which is in the incorrect position, cannot be mounted in the adjustment receiving element. Consequently, communication quality is less likely to be reduced due to incorrect positioning of the impedance adjuster, and a short circuit between the terminals cannot occur.Furthermore, the impedance adjustment element cannot be moved forward relative to the unshielded sections due to vibration or oscillation.

[0020] The position error detection section can be a partition that separates the connections from each other in the element receiving the connection.

[0021] According to such a configuration, incorrect positioning of the impedance adjustment element can be detected by the partition that defines each of the cavities in the connector receiving element. Therefore, a separate detection section for incorrect positioning does not need to be provided within the connector receiving element, and the shape or design of the connector receiving element is less likely to become complex.

[0022] The technology described herein includes the connection module, an outer conductive element which encloses or covers an outer circumference of the connection module, and a housing in which the connection module, which is covered with the outer conductive element, is arranged. [Advantageous effects of the invention]

[0023] According to the technology described herein, it is less likely that communication quality will be reduced or lowered.

[0024] An embodiment according to the technology described herein is described with reference to Fig. 1 to 23 are described.

[0025] In the present embodiment, a connector 10, which serves for communication and is mounted or arranged in vehicles, such as an electric vehicle or a hybrid vehicle, will be described as an example. For example, the connector 10 is arranged in a wired communication network between electrical devices installed in a vehicle (such as a vehicle navigation system, an ETC system, and a monitor) and an external device (such as a camera).

[0026] As this is in Fig. As illustrated in Figures 1 to 4, the connector 10 comprises a shielded electrical wire 11, internal conductive elements 20 (an example of a connection) connected to a front end of the shielded electrical wire 11, a connection receiving element 30 in which the internal conductive elements 20 are arranged, an outer conductive element 50 connected to the shielded electrical wire 11 while sheathing or covering an outer circumference of the connection receiving element 30, and a housing 70 in which the outer conductive element 50 is arranged.

[0027] The shielded electrical wire 11 comprises sheathed or covered wires 12, a shielding section 15, and an outer casing 16. The shielding section 15 is formed from stranded wires and jointly encases the outer circumferences of the sheathed wires 12. The outer casing 16 is formed from an insulating cover and encases or covers an outer circumference of the shielding section 15. In the shielded electrical wire 11 of the present embodiment, the two sheathed wires 12 are covered or encased together with the shielding section 15.

[0028] Each of the sheathed wires 12 comprises an electrically conductive core wire 13 and an insulating cover or sheath 14 with which the core wire 13 is sheathed or covered. The two sheathed wires 12, which are sheathed with the shielding section 15, are twisted together. The sheath 16 is removed from the front end section of the shielded electrical wire 11, the two sheathed wires 12 are untwisted, and the shielding section 15 is stripped of its outer sheath.

[0029] The insulating cover 14 is removed from the front end section of each sheathed wire 12 that protrudes from the end of the sheath 16, and the core wires 13 are stripped of their sheathing. The stripped or unsheathed core wires 13 are or are electrically connected to or attached to the respective inner conductive elements 20.

[0030] The shielding section 15 is formed from electrically conductive thin metallic wires twisted or braided into a tubular shape. The portion of the shielding section 15 that projects from the end of the sheath 16 is folded backward onto the outer circumference of the end section of the sheath 16 and is configured as a folded section 15A. The folded section 15A covers the outer circumference of the end section of the sheath 16.

[0031] Each of the inner conductive elements 20 is formed by pressing a metal plate that has electrically conductive properties. Each of the inner conductive elements 20 is a so-called receiving or socket connection and comprises a tubular connecting section 22 and a wire connecting section 24. The tubular connecting section 22 has a square, tubular shape, and a pin or prong of a receiving or plug connection (not illustrated) is inserted into the tubular connecting section 22 and connected to it. The wire connecting section 24 then extends backward from the tubular connecting section 22 and is crimped onto the core wire 13 and thus connected to it.

[0032] The connecting element 30 is made of a synthetic or artificial resin and has a rectangular or right-angled square shape, which is extended in a forward-backward direction, as shown in Fig. 20 is illustrated.

[0033] As this is in Fig. 3 and Fig. As illustrated in Figure 22, the connecting element 30 includes cavities 31 in a front section or cross-section thereof relative to a middle cross-section in the forward-backward direction. The cavities 31 are arranged in a right-left direction, and each cavity 31 extends in the forward-backward direction. Each cavity 31 can receive the inner conductive element 20, which is connected to the sheathed wire 12.

[0034] The connecting element 30 includes a large receiving or housing section 32 at a rear cross-section thereof. The sheathed wires 12, which extend rearward from the respective cavities 31, are or will be arranged together in the large receiving section 32.

[0035] As this is in Fig. 19 and Fig. As illustrated in Figure 20, the connecting member 30 comprises a lower member or element 33, which is arranged in a lower cross-section, and an upper member or element 40, which is arranged in an upper cross-section. The lower member 33 and the upper member 40 are fitted together in the upward-downward direction.

[0036] As this is in Fig. 4 and Fig. As illustrated in Figure 4, the lower member 33 includes a bottom wall 33D and two stop pieces 34. The bottom wall 33D is configured as a lower wall 30D of the member 30 that receives the connection. The lower member 33 includes the two stop pieces 34 on two side edges of the bottom wall 33D. The bottom wall 33D is a rectangular plate that extends in the forward-backward direction. The two inner conductive members 20 are arranged on the bottom wall 33D in the right-left direction.

[0037] The stop pieces 34 extend upwards from rear edge or side sections of the bottom wall 22D and each of the stop pieces 34 includes a square stop hole 34A which extends through the stop piece 34 in the right-left direction.

[0038] As this is in Fig. 4, Fig. 8 and Fig. As illustrated in Figure 16, the upper member 40 includes a ceiling wall 40U, a front wall 42 at a front edge of the ceiling wall 40U, and side walls 44 at two side edges of the ceiling wall 40U in the right-left direction. The ceiling wall 40U is configured or constructed as an upper wall 30U of the member 30 receiving the connection.

[0039] The ceiling wall 40U is a rectangular panel that extends in the forward-backward direction. The ceiling wall 40U includes a partition 45 at a central cross-section relative to the right-left direction. The partition 45 extends downwards from the ceiling wall 40U. The partition 45 is located close to and opposite the bottom wall 33D of the lower member 33 in the upward-downward direction when the upper member 40 and the lower member 33 are fitted together. In this way, the two inner conductive members 20 are separated by the partition 45 in the member 30 that receives the connection.

[0040] The front wall 42 is a panel that extends downwards from the front edge of the ceiling wall 40U. The front wall 42 includes insertion holes 42A through which the plug connectors are to be inserted.

[0041] The side walls 44 extend downwards from the ceiling wall 40U and are adjacent to the respective two side edges of the front wall 42 relative to the right-left direction.

[0042] Each of the side walls 44 includes a fitting recess 44A at a central cross-section in the forward-backward direction. The stop pieces 34 of the lower member 33 are fitted into the respective fitting recesses 44A when the upper member 40 and the lower member 33 are fitted together. The fitting recess 44A has an opening edge in the side wall 44, which extends from its lower edge to the top wall 40U in the upward-downward direction. The fitting recess 44A includes a fitting projection 46 on the side edge of the top wall 40U. The fitting projection 46 extends outwards from the side edge of the top wall 40U.

[0043] As this is in Fig. As illustrated in Figure 22, the fitting projections 46 are inserted into the respective stop holes 34A of the stop pieces 34 when the upper link 40 and the lower link 33 are fitted together and the stop pieces 34 of the lower link 33 are fitted into the respective fitting recesses 44A. In this way, the upper link 40 and the lower link 33 are held in the fitted state.

[0044] As this is in Fig. 3 and Fig. As illustrated in Figure 4, the outer conductive element 50 comprises a first outer conductive element 51 and a second outer conductive element 60. The first outer conductive element 51 covers an outer circumference of the connecting element 30. The second outer conductive element 60 is fitted onto the first outer conductive element 51 to cover or encase an outer circumference of the folded section 15A of the shielded electrical wire 11.

[0045] The first outer conductive element 51 is formed by pressing an electrically conductive metal plate and includes a tubular section 52 and a shielding connection section 53 at a rear end of the tubular section 52. The connection receiving element 30 is arranged in the tubular section 52.

[0046] The tubular section 52 has a square tubular shape, which appears as a rectangular shape in an elevation view. The housing 30, which receives the connection, is inserted from the rear of the tubular section 52 and arranged within it.

[0047] As this is in Fig. As illustrated in Figure 3, the shielding connection section 53 comprises a connection section 54 and a plate section 55. The connection section 54 extends obliquely towards a rear lower side from a lower rear end of the tubular section 52. The plate section 55 extends straight rearward from a rear end of the connection section 54.

[0048] The plate piece 55 is a square plate and is arranged along the lower outer circumferential surface of the folded section 15A of the shielded electrical wire 11 when the connection receiving element 30 is arranged in the tubular section 52.

[0049] The second outer conductive element 60 is formed by pressing an electrically conductive metal plate. How this is done in Fig. 3 and Fig. As illustrated in Figure 4, the second outer conductive member or element 60 comprises a ceiling plate 61, a pair of fixing or fastening drums 62, and a pair of connecting drums 63. The ceiling plate 61 extends along the tubular section 52 and the folded section 15A of the shielded electrical wire 11. The fixing or fastening drums or sleeves 62 extend from a front section of the ceiling plate 61. The connecting drums or sleeves 63 extend from a rear section of the ceiling plate 61.

[0050] The ceiling plate 61 has a surface that covers the rear section of the tubular section 52 and the folded section 15A from an upper side. The ceiling plate 61 includes a lance hole 61A in a front section thereof, and the lance hole 61A extends vertically through the ceiling plate 61.

[0051] The two securing drums 62 extend from the right and left side edges of the front section of the ceiling plate 61. The securing drums 62 are crimped onto the rear section of the tubular section 52 from the right and left sides and wrapped around it.

[0052] The two connecting drums 63 are provided continuously or adjacently on a rear side of the fixing drums 62 and extend from a right and left side edge of the rear section of the ceiling panel 61. The connecting drums 63 are crimped onto the folded section 15A from the right and left sides and wrapped around it.

[0053] One of the connecting drums 63 includes a side plate 64 and a fixing or securing piece 65. The side plate 64 extends along one of the right and left side sections of the folded section 15A. The fixing or securing piece 65 extends upwards from an upper edge of the side plate 64. Another of the connecting drums 63 includes a side plate 64 extending along another of the right and left side sections of the folded section 15A, and two fixing or securing pieces 65 extending upwards from an upper edge of the side plate 64.

[0054] The fixing pieces 65 are crimped onto and wrapped around the folded section 15A and the plate piece 55, which is positioned on the upper surface of the folded section 15A. Each of the fixing pieces 65 includes a hook section 66 at a distal end thereof, and the distal end is folded backwards and inwards to be configured or constructed as the hook section 66.

[0055] When the fixing pieces 65 are crimped, one of the right and left side edges of the plate piece 55 is hooked by the hook section 66 in such a way that the fixing pieces 65 are fixed so as not to be released by the shielding section 15. Accordingly, as shown in Fig. Figure 3 illustrates the outer conductive element 50, which includes the first outer conductive element 51 and the second outer conductive element 60, electrically connected to and fixed to the shielding section 15 of the shielded electrical wire 11.

[0056] The housing 70 is made of a synthetic or artificial resin and includes a cross-section 72 accommodating the outer conductive element, in which the outer conductive element 50, which is connected to the shielded electrical wire 11, is or will be arranged.

[0057] The cross-section 72 receiving the outer conductive element has a square, tubular shape, extending in the forward-backward direction. The cross-section 72 receiving the outer conductive element contains a lance 73, which is to be fitted into the lance hole 61A and held or stopped by an edge of the lance hole 61A of the outer conductive element 50. When the outer conductive element 50 is in a correct arrangement position, the lance 73 is fitted into the lance hole 61A and stopped or held by the edge of the lance hole 61A, and the outer conductive element 50 is held within the housing 70.

[0058] The rear sections of the two covered or sheathed wires 12 extend backwards from the respective cavities 31 of the connecting element 30. As shown in Fig. As illustrated in Figures 12 to 20, the rear sections of the two sheathed wires 12 are unsheathed or uncovered sections 17, which are not covered or sheathed by the covering 16 of the shielded electrical wire 11, and an impedance adjusting element 80 is or is fixed or arranged on the unsheathed sections 17.

[0059] The impedance adjusting element 80 is formed by pressing a metal plate that has electrically conductive properties. The impedance adjusting element 80 comprises adjusting body sections 82 and a connecting section 85. The adjusting body sections 82 are fixed to the outer circumferences of the uninsulated sections 17 of the insulated wires 12. The connecting section 85 connects the adjusting body sections 82. The two adjusting body sections 82, which are fixed to the respective two uninsulated sections 17 of the two insulated wires 12, are connected to each other by the connecting section 85 and are thus configured as the impedance adjusting element 80 of the present embodiment.

[0060] Each of the adjusting body sections 82 has a substantially circular, tubular shape extending along the outer circumferential surface of the unclad section 17 to cover approximately three-quarters of the outer circumferential surface of the unclad section 17 relative to the circumferential direction. A side opening 83 is provided between the opposing adjusting body sections 82, and the side opening 83 is open in a radial direction. Each of the adjusting body sections 82 has a slot 84 at a central portion of an opening edge of the side opening 83 relative to the forward-backward direction. The slot 84 extends in the circumferential direction.

[0061] The adjusting body sections 82 are fixed to the middle sections of the respective unclad sections 17 relative to the forward-backward direction. The length dimension of the adjusting body section 82 relative to the forward-backward direction is slightly smaller than the length dimension of the unclad section 17 relative to the forward-backward direction.

[0062] Therefore, a front section and a rear section of the unclad section 17 project slightly from the adjusting body section 82 and are not covered by it. Approximately one quarter of the unclad section 17 in the circumferential direction is exposed by the side opening 83, which opens in the radial direction of the adjusting body section 82, and is not covered or clad by the adjusting body sections 82.

[0063] The connecting section 85 connects the two adjustment body sections 82 relative to the right-left direction, such that the opening edges of the side opening 83 of the respective adjustment body sections 82 are opposite each other in the right-left direction. The connecting section 85 is curved or bent to project upwards.

[0064] As this is in Fig. As illustrated in Figure 13, the connecting section 85 is wider in the front section than in the rear section relative to the right-left direction. As shown in Fig. 16 and Fig. As illustrated in Figure 17, the connecting section 85 is designed such that the distance between the adjusting body sections 82, which connect to the front end section of the connecting section 85, is essentially equal to the distance between the inner conducting elements 20, which are arranged in the element 30 receiving the connection.

[0065] In other words, the connecting section 85 connects the two adjusting body sections 82 such that the distance between the two sheathed wires 12, to which the respective adjusting body sections 82 are fixed, is substantially equal to the distance between the inner conductive elements 20, which are arranged in the connecting element 30. The configuration in which the distances are substantially equal includes a configuration in which the distance between the sheathed wires 12 is the same as the distance between the inner conductive elements 20, and also a configuration in which the distance between the sheathed wires 12 is not directly the same as the distance between the inner conductive elements 20.

[0066] As this is in Fig. As illustrated in Figure 17, the large receiving or housing section 32 of the terminal receiving element or terminal housing element 30 can accommodate the unshielded sections 17 of the two sheathed wires 12 and the impedance adjusting element 80 therein. The large receiving section 32, which accommodates the impedance adjusting element 80, is provided in a region of the terminal receiving element 30, and the width of the front end of the region for the large receiving section 32 is greater than the width of a region for the two cavities 31.

[0067] Each of the right and left side walls 30A of the receiving element 30 includes a body position detection section 47 (an example of a position error detection section) on a portion thereof between the cavity area 31 and the large receiving section 32. The body position detection section 47 projects toward an area in which the sheathed wires 12 are arranged. The body position detection sections 47 are located upstream of the adjusting body sections 82 when the impedance adjusting element 80, which is fixed to the unsheathed sections 17, is located in the large receiving section 32.

[0068] The partition 45, which separates the two inner conductive elements 20 from each other in the connection receiving element 30, includes a center position detection section 48, or a detection section of a central or mid-position (an example of a position error detection section), at a rear end section thereof. The center position detection section 48 is arranged upstream of the connecting section 85 when the impedance adjusting element 80, which is fixed to the unshielded sections 17, is arranged in the large housing section 32.

[0069] As this is in Fig. As illustrated in Figures 17 to 19, if the impedance adjusting element 80 is fixed in the correct position on the unshielded sections 17, the body position detection sections 47 and the detection section 48 of the central position allow the impedance adjusting element 80 to be arranged in the large receiving or housing section 32. On the other hand, if the impedance adjusting element 80 is fixed in an incorrect position on the unshielded sections 17 and is displaced forward from the correct position, the adjusting body sections 82 are contacted with the body position detection sections 47, or the connecting section 85 is contacted with the detection section 48 of the central position, as shown in Figures 17 to 19. Fig. Figure 23 illustrates this. Therefore, the impedance adjusting element 80 cannot be inserted into the element 30 that receives the connection.

[0070] The present embodiment has the configuration described above. Next, an example of the assembly steps for connector 10 for communication will be described, and the processes, actions, and effects of connector 10 will be further described.

[0071] First, a section of the sheath 16 of the shielded electrical wire 11 is removed to expose the end sections of the two sheathed wires 12 and the shielding section 15. The exposed, or unsheathed, shielding section 15 is folded back onto the outer surface of the sheath 16 to form the folded section 15A. The leading end sections of the insulating covers 14 of the two sheathed wires 12 are removed to expose the core wires 13. As shown in Fig. As illustrated in Figure 9, the wire connection sections 24 are crimped onto the uninsulated or exposed core wires 13 to connect the inner conductive elements 20 to the sheathed wires 12.

[0072] Next, the impedance adjusting element 80 is set on the unshielded sections 17 of the two sheathed wires 12 of the shielded electrical wire 11.

[0073] As this is in Fig. As illustrated in Figures 5 to 7, the impedance-adjusting element 80, which is in an unfolded state before being fixed to the unclad or exposed sections 17, comprises the connecting section 85, two bottom sections 82A, and extending pieces 82B. The bottom sections 82A are each adjacent to or continuous with the side edges of the connecting section 85. The extending pieces 82B are continuous with the side edges of the respective bottom sections 82A that are opposite the connecting section 85. Each of the connecting section 85 and the bottom sections 82A is slightly wider at the front than at the rear.

[0074] When the impedance adjusting element 80 is set at the unshielded sections 17 of the two shielded wires 12, as shown in Fig. As illustrated in Figure 11, the uninsulated sections 17 of the insulated wires 12 are placed on the two respective bottom sections 82A, and the extending pieces 82B and the respective uninsulated sections 17 are crimped and wound or wrapped around them. Accordingly, as shown in Fig. As illustrated in Figures 12 to 16, the adjusting body sections 82 of the impedance adjusting element 80 are fixed to the outer circumferences of the respective unshielded sections 17. In this way, an electrical wire with a terminal 25 is completed.

[0075] If the impedance adjusting element 80 is fixed to the unshielded sections 17 of the two shielded wires 12, the distance between the two shielded wires 12, to which the respective adjusting element sections 82 are fixed, is essentially equal to the distance between the inner conductive elements 20, which are to be arranged in the connecting element 30.

[0076] As this is in Fig. As illustrated in Figure 16, the two inner conductive elements 20 of the completed electrical wire are or will be mounted with a connection 25 on the ceiling wall 40U of the upper element 40 of the element 30 receiving the connection, which is or will be arranged with the top facing downwards.

[0077] When the inner conductive elements 20 are mounted in their respective correct mounting positions on the ceiling wall 40U of the upper element 40, the inner conductive elements 20 must be positioned relative to these positions. In the present embodiment, the distance between the two sheathed wires 12 is essentially equal to the distance between the inner conductive elements 20, which are to be arranged in the connection-receiving element 30. Therefore, the inner conductive elements 20 do not need to be positioned relative to their respective correct mounting positions on the ceiling wall 40U of the upper element 40, and the two inner conductive elements 20 can be mounted in their respective correct mounting positions as shown in [reference to figure]. Fig. 17 and Fig. 18 is illustrated by simply arranging the electrical wire with a terminal 25 on the ceiling wall 40U of the upper member 40 from the top side.

[0078] The lower link 33 is mounted on the upper link 40 from the top, after the electrical wire with a terminal 25 is mounted on the ceiling wall 40U of the upper link 40. As shown in Fig. As illustrated in Figures 20 to 22, a connection module 49 is completed by fixing the connection receiving element 30 to the electrical wire with a connection 25.

[0079] Next, the receiving element 30 of the connection module 49 is inserted from the rear into the tubular section 52 of the first outer conductive element 51 of the outer conductive element 50 to fix the first outer conductive element 51 to the outer circumference of the receiving element 30 of the connection module 49. Then, the second outer conductive element 60 is fixed to the first outer conductive element 51.

[0080] The second outer conductive link 60 is fixed to the first outer conductive link 51 as follows. The first outer conductive link 51 is positioned on the top plate 61 of the second outer conductive link 60 such that the plate section 55 of the first outer conductive link 51 is located on its upper side. The fixing drums 62 are crimped onto and wrapped around the tubular section 52, and the fixing or fixing pieces 65 of the respective connecting drums 63 are crimped onto and wrapped around the plate section 55 and the shielding section 15. Then, the hook section 66 of the fixing piece 65 is hooked onto the side edge of the plate section 55 in such a way that the fixing piece 65 is not released from the plate section 55 and the shielding section 15.

[0081] Next, the connection module 49, to which the outer conductive element 50 is attached, is inserted from the rear into the receiving or housing cross-section 72 of the housing 70. When the outer conductive element 50 reaches the correct receiving or housing position, as shown in Fig. As illustrated in Figure 3, the lance 73 is fitted into the lance hole 61A of the outer conductive element 50 in such a way that the outer conductive element 50 is held in the housing 70 so that it cannot be released or detached from the housing 70. In this way, the connector 10 is completed for communication.

[0082] Next, the processes, actions, and effects of connector 10 for communication will be described.

[0083] To connect the inner conductive elements 20 to the sheathed wires 12 of the shielded electrical wire 11, the sheath 16 at the end of the shielded electrical wire 11 must be removed and the shielding section 15 must be folded back. In such a configuration, signal reflection can occur in the unsheathed sections 17 of the sheathed wires 12, which are not covered or sheathed by the shielding section 15 at the end of the shielded electrical wire 11, and this can reduce or lower the communication quality.

[0084] As a result of the inventors' serious investigations into solving the problems mentioned above, they devised the configuration and structure of the present embodiment. The connector 10 for communication of the present embodiment comprises the shielded electrical wire 11 and the inner conductive elements 20 (a terminal). The shielded electrical wire 11 comprises at least one sheathed wire 12, the shielding section 15, which has electrically conductive properties, and the sheath 16. The sheathed wire 12 comprises the core wire 13, through which communication signals are transmitted, and the insulating cover 14, which has insulating properties and covers the core wire 13. The shielding section 15 covers an outer circumference of the sheathed wire 12.The sheath 16 covers or encases an outer circumference of the shielding section 15. The inner conductive element 20 is or will be connected to the sheathed wire 12. The sheathed wire 12 includes an end section near the inner conductive element 20 (a front face), which projects from the sheath 16 and the shielding section 15 and is not covered by them, and is configured or constructed as the unsheathed or exposed section 17. As shown in . Fig. As illustrated in Figures 12 to 15, the unclad section 17 is covered or cladding with the impedance adjusting element 80, which has an electrically conductive property.

[0085] According to the present embodiment, the unshielded section 17 of the sheathed wire 12 is sheathed or covered by the impedance-adjusting element 80, which has electrically conductive properties. The unshielded section of the sheathed wire 12, which projects from and is exposed by the shielding section 15, is covered by the electrically conductive element, and the electrically conductive element extends to cover or enclose the unshielded section of the sheathed wire 12 that projects from the shielding section 15 immediately before the end section, in order to be connected to the inner conductive element 20. According to such a configuration, it is less likely that the impedance will change between the sheathed wire 12, which is covered or encased by the shielding section 15, and the unshielded section 17.This prevents a decrease in the communication quality of the sheathed wire 12.

[0086] The shielded electrical wire 11 includes the sheathed wires 12, and the impedance adjusting element 80 includes the adjusting body sections 82, which have a tubular shape. The adjusting body sections 82 are fitted onto the respective unsheathed sections 17 and arranged along the outer circumferential surfaces of the unsheathed sections 17.

[0087] Since the unshielded sections 17 of the sheathed wires 12, which protrude from the shielding section 15, are each covered by the adjustment element sections 82 independently of one another, each adjustment element section 82 can independently suppress a change in the impedance of the corresponding unshielded section 17 of the sheathed wires 12. Therefore, the impedance is less likely to change at the unshielded section 17 compared to a configuration in which the unshielded sections 17 of the sheathed wires 12 are covered or sheathed together with an impedance adjustment element.

[0088] The adjusting body section 82 has the slot 84, which extends in the circumferential direction, and the area of ​​the adjusting body section 82 that covers or encloses the unclad section 17 can be easily changed by altering the size of the slot 84. Therefore, the impedance in the unclad section 17 can be easily adjusted.

[0089] Specifically, the accuracy of impedance adjustment in the unshielded section 17 can be improved. This further suppresses signal reflection between the shielded wire 12, which is sheathed in the shielding section 15, and the unshielded section 17, and thus further prevents a decrease or reduction in communication quality.

[0090] The impedance adjustment element 80 further includes the connecting section 85, which connects the adjustment body sections 82. With such a configuration, the number of components contained in the impedance adjustment element 80 is reduced compared to a configuration which includes adjustment body sections, each of which is prepared separately for each of the unshielded sections.

[0091] As this is in Fig. As illustrated in Figures 20 to 22, the connector 10 for communication further includes the connection receiving element or connection housing element 30, in which the inner conductive elements 20 are arranged. The connecting section 85 connects the adjusting body sections 82 such that the distance between the sheathed wires 12 is essentially equal to the distance between the inner conductive elements 20, which are to be arranged in the connection receiving element 30.

[0092] In particular, the connecting section 85 of the impedance adjusting element 80 can adjust the distance between the sheathed wires 12 to match the distance between the inner conductive elements 20 in the terminal receiving element 30. This improves the ease of mounting the inner conductive elements 20 in the terminal receiving element 30 compared to a configuration in which each of the inner conductive elements 20 is positioned and mounted in each of the cavities 31.

[0093] The receiving element 30 includes the large receiving or housing section 32 (a receiving element section or receiving element housing section) in which the impedance adjusting element 80 is or will be arranged. The receiving element 30 includes the body position detection sections 47 and the detection section 48 of the central position (the position error detection section) between the cavities 31 for receiving the inner conductive elements 20 and the large receiving section 32. The impedance adjusting element 80 is or will be contacted with the body position detection sections 47 and the detection section 48 of the central position if the impedance adjusting element 80 is or will not be mounted or arranged in the correct position relative to the unencased sections 17.

[0094] For example, if the impedance adjusting element 80 is mounted in an incorrect position relative to the unshielded sections 17 of the sheathed wires 12, the impedance cannot be effectively adjusted in the unshielded sections 17, and the communication quality may be reduced. If the impedance adjusting element 80 is mounted closer to the inner conductive elements 20, the inner conductive elements 20 may not be able to make contact with the impedance adjusting element 80, and a short circuit may occur between the inner conductive elements 20.

[0095] In the connector 30 of the present embodiment, if the impedance adjusting element 80 is mounted in an incorrect position and closer to the front face relative to the unshielded sections 17, the following problems can occur. As this is shown in Fig. As illustrated in Figure 23, the adjusting body sections 82 of the impedance adjusting element 80 can be contacted with the body position detection section 47, or the connecting section 85 can be contacted with the detection section 48 of the central position, when the impedance adjusting element 80 is mounted in the large receiving section 32. Therefore, the impedance adjusting element 80, which is in the incorrect position, cannot be mounted in the large receiving section 32.

[0096] In particular, according to the present embodiment, the communication quality is less likely to be negatively affected by incorrect positioning of the impedance adjusting element 80 relative to the unshielded sections 17, and a short circuit cannot occur between the inner conductive elements 20. Furthermore, the impedance adjusting element 80 cannot be moved forward relative to the unshielded sections 17 due to vibration or oscillation.

[0097] The detection section 48 of the central position is defined as the partition 45, which separates the inner conductive elements 20 from each other in the connection receiving element 30. In particular, the incorrect positioning of the impedance adjustment element 80 can be detected by the partition 45, which defines each of the cavities 31 in the connection receiving element 30. Therefore, a separate detection section for an incorrect position does not need to be provided in the connection receiving element 30, and the shape of the connection receiving element 30 is less likely to become complicated. <Andere Ausführungsformen>
