[0004] [Patent document 1] Japanese unexamined patent application JP 2005-317267A

[0005] The subsequently published EP 3 726 667 A1 discloses a connector for high-frequency transmissions in the automotive sector, an impedance enhancer element, a connection arrangement, and a method for impedance enhancement in a connector. The application shows a connector for high-frequency transmissions in the automotive sector comprising a contact element arranged in an interior of the connector and suitable for making contact with an electrical connection element such as a cable or a mating connector, wherein the connector further comprises an impedance enhancer element arranged on one side of the electrical connection element, the impedance enhancer element comprising a receiving channel through which the contact element extends and a deformation section adapted to be deformed, at least either radially or axially.Furthermore, a connection assembly is disclosed comprising a connector and a cable attached to the connector, wherein the deformation section seals and / or retains a dielectric insulation of the cable (14). A method for improving the impedance in a connector with a contact element is also disclosed, wherein an impedance improvement element is used, the impedance improvement element comprising a receiving channel for the contact element and a deformation section that can be deformed.

[0006] EP 0 006 343 A1 discloses a coaxial connector for use as an insert in a first connector housing, comprising a first generally cylindrical outer shell, a socket centered on the axis of the shell and a sleeve made of electrically insulating material between the socket and the shell.The front end of the insulating sleeve extends beyond the front end of the socket and has circumferential regions defining a first male frustoconical or other convex surface. It is used in combination with a coaxial socket connector as an insert in a second connector housing and has a second, generally cylindrical, outer shell dimensioned to fit the first outer shell, a contact pin centered on the axis of the second shell, and an insulating sleeve whose front end is recessed behind the front end of the contact pin and has regions forming complementary frustoconical surfaces to those at the front end of the connector. In use, the convex surface of the connector helps prevent misalignment between the plug and socket during mating of the first and second connector housings. [SUMMARY OF THE INVENTION][Problem to be solved by the invention]

[0007] Generally, the characteristic impedance is set to a predefined value to perform impedance matching in a transmission line for transmitting high-frequency signals. Therefore, impedance matching is performed between the coaxial cable, the inner conductor, and the core wire terminal of the connector. However, a gap can be created in the connector described above between the leads of the female connector and the male connector if the female and male connectors are coupled. If this occurs, there is no ground connection between the core wire terminal and the electrically grounding element in the gap between the leads, and the relative permittivity in the gap changes, resulting in a high impedance.This can cause an impedance mismatch in the gap, resulting in a reflection of transmission signals and potentially lowering or reducing transmission efficiency.

[0008] The technology for suppressing an impedance change is revealed herein. [Means to solve the problem]

[0009] A connector as described herein comprises a socket module and a plug module that connects to the socket module. The socket module includes an electrically conductive inner conductor, an insulating outer conductor, and an electrically conductive outer conductor. The outer conductor connects to the socket's inner conductor via the socket's outer conductor. The plug module includes an electrically conductive inner conductor, an insulating outer conductor, and an electrically conductive outer conductor.The outer conductor on the plug side receives the inner conductor on the plug side via the plug-side connection and is connected to the outer conductor on the socket side when the socket and plug modules are coupled. The socket-side connection includes a socket-side mating section. The plug-side connection includes a plug-side mating section. When the socket and plug modules are coupled in a coupling direction, the socket-side mating section and the plug-side mating section are fitted to each other in the coupling direction with a recess and protrusion. The inner conductor on the plug side includes a receiving or plug connection section.The plug connection section extends further than the plug-side mating section towards the socket terminal module. When the socket terminal module and the plug terminal module are coupled, the plug connection section is inserted into the socket-side mating section and connected to the socket-side inner conductor. The socket-side termination has a socket-side front termination with a socket-side body section. The rear end section of the socket-side body section is compressed in an upward-downward direction and fixed to a connection section of an electrical wire by crimping a socket-side front outer conductor of the socket-side outer conductor.

[WAYS OF IMPLEMENTING THE INVENTION][Description of embodiments according to the present disclosure]

[0011] First, embodiments according to the present disclosure will be listed and described.

[0012] (1) A connector comprises a socket module and a plug module, which is to be coupled to the socket module. The socket module comprises an electrically conductive inner conductor, an insulating conductor, and an electrically conductive outer conductor. The outer conductor receives the inner conductor via the outer conductor. The plug module comprises an electrically conductive inner conductor, an insulating conductor, and an electrically conductive outer conductor.The plug-side outer conductor receives the plug-side inner conductor via the plug-side lead and is connected to the socket-side outer conductor when the socket and plug modules are coupled. The socket-side lead includes a socket-side mating section. The plug-side lead includes a plug-side mating section. When the socket and plug modules are coupled in a coupling direction, the socket-side mating section and the plug-side mating section are fitted to each other in the coupling direction by a fit of a recess and a projection. The plug-side inner conductor includes a plug connection section.The plug connection section extends further than the plug-side mating section towards the socket connector module. When the socket connector module and the plug connector module are coupled together, the plug connection section is inserted into the socket-side mating section and connected to the socket-side inner conductor.

[0013] When the connector section, which projects from the plug-side fitting section, is inserted into the socket-side fitting section and connected to the socket-side inner conductor after coupling the socket connection module and the plug connection module, the socket-side fitting section and the plug-side fitting section are fitted to each other in the coupling direction with the alignment of a recess and protrusion. Therefore, at least the plug-side fitting section or the socket-side fitting section is arranged around the connector connection section.

[0014] Accordingly, the relative permittivity is less likely to change in the connector section, thus keeping the impedance change small. Therefore, the reflection loss of high-frequency signals can be minimized, and the transmission frequency is less likely to be attenuated or reduced.

[0015] (2) One mating section of the socket-side mating section and the plug-side mating section is a protruding member and includes a first tapered surface, and another mating section of the socket-side mating section and the plug-side mating section is a recessed member and includes a second tapered surface. The first tapered surface is inclined to be closer to an axis of the plug-connection section as it extends closer to the other mating section. The second tapered surface is inclined to be closer to the axis of the plug-connection section as it extends farther away from the first mating section, and the second tapered surface extends along the first tapered surface.

[0016] Generally, a space is provided between a distal end of the plug-side mating section and a distal end of the socket-side mating section in a section where the plug connection section is inserted into the socket-side mating section. This prevents the plug-side mating section from contacting or striking the socket-side mating section in the coupling direction and ensures that the mating of the mating sections does not fail.

[0017] For example, if one mating section of the plug-side mating section and the socket-side mating section has a circular column-like shape, and another mating section of the mating sections includes a circular column-like recess, a space created around the outer circumference of the connector near a recessed bottom of the recess has a diameter that is the same as the inner diameter of the recess. Therefore, the impedance change tends to be large in the connector.

[0018] However, according to the configuration above, one fitting section is the projecting or raised member, which includes the first tapered surface, and the other fitting section is the recessed or offset member, which has the second tapered surface.

[0019] Specifically, the other fitting section, which is the recessed element, has an interior space that decreases as it approaches the recessed base. This reduces the space around the outer circumference of the receiving or connector section near the recessed base of the other fitting section. Consequently, the impedance change in the connector section can be significantly reduced, and the reflection loss of high-frequency signals in the connector section can be further decreased. Even if a first tapered surface and a second tapered surface are not fully in contact, the space between them can be uniform, and a local impedance change is less likely to occur.

[0020] (3) The first tapered surface is formed in a conical shape which tapers towards a distal end, and the second tapered surface is formed in a conical shape whose diameter is reduced as it extends closer to a recessed or depressed base of the recessed segment.

[0021] The other mating section, which is the recessed element, has a smaller space around the plug-connection section and near the recessed base due to the second tapered surface. Therefore, the space between the plug-side mating section and the socket-side mating section can be made smaller compared to a configuration that includes a second tapered surface in one section of the other mating section. Consequently, the impedance change can be made much smaller, and the reflection loss of high-frequency signals can be further reduced.

[0022] (4) The first tapered surface and the second tapered surface are or will be in close or direct contact with each other when the socket connector module and the plug connector module are or will be coupled together.

[0023] The direct and close contact between the first tapered surface and the second tapered surface further reduces the space between the socket-side mating section and the plug-side mating section. Consequently, the impedance change can be significantly reduced, and the reflection loss of high-frequency signals can be further minimized.

[0024] (5) The connector further comprises a socket housing in which the socket connection module is arranged and a plug housing in which the plug connection module is arranged and which can be coupled to the socket housing. [Detail of an embodiment according to the present disclosure]

[0025] Embodiments of the connector according to the present disclosure will be described with reference to the drawings. The present disclosure is not limited to these embodiments. All modifications or variations within the technical scope of the claimed invention and equivalents thereto may be included within the technical scope of the present disclosure. <Erste Ausführungsform>

[0026] A first embodiment according to the present disclosure is described with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 will be described.

[0027] A connector 10 according to this embodiment serves to connect or link electrical devices which are installed in a vehicle and to transmit high frequency electrical signals. [Connector 10]

[0028] As this is in Fig. 1 and Fig. As illustrated in Figure 2, connector 10 comprises a plug connector 20 and a socket connector 60. Plug connector 20 is to be connected to one end of a shielded electrical wire W. Socket connector 60 is to be connected to one end of a shielded electrical wire W and coupled to plug connector 20. In the following description, a front side is defined with reference to a coupling direction, in which a corresponding plug connector 20 and socket connector 60 are coupled to each other. [Shielded electrical wire W]

[0029] As this is in Fig. As illustrated in Figure 2, the shielded electrical wire W is a coaxial cable comprising a core wire W1, a stranded conductor W2, and an outer cover W3. The outer circumference of the core wire W1 is covered by the braided conductor W2, and the outer circumference of the stranded conductor W2 is covered by the outer cover W3. The stranded conductor W2 and the outer cover W3 are removed from the shielded electrical wire W in the front end section, and the insulating conductor is also removed, exposing the core wire W1. Only the outer cover W3 is removed from the shielded electrical wire W in the section behind the exposed core wire W1, exposing the stranded conductor W2. [Connector 20]

[0030] As this is in Fig. 1 and Fig. As illustrated in Figure 2, the connector 20 includes a connector housing 21 and a connector connection module 30. [Connector housing 21]

[0031] The connector housing 21 is a tubular element made of an insulating synthetic resin. The connector housing 21 can receive the connector module 30 from its rear side. The connector housing 21 contains a stop, which is not illustrated. When the connector module 30 reaches the correct position within the connector housing 21, it stops against this stop. Thus, the connector module 30 is held within the connector housing 21 to prevent it from slipping out. [Connector module 30]

[0032] As this is in Fig. As illustrated in Figure 2, the plug connector module 30 includes a plug-side inner conductor 31, a plug-side outgoing conductor 40 and a plug-side outer conductor 50. [Inner conductor on the plug side 31]

[0033] The inner conductor 31 on the connector side is formed by machining an electrically conductive metal plate. How this is done in Fig. 2, Fig. 3 and Fig. As illustrated in Figure 8, the plug-side inner conductor 31 includes a plug connection section 32 and a connection section of an electrical wire 33, which lies behind the plug connection section 32.

[0034] The plug connection section 32 has a pin shape that extends in the forward-backward direction. The plug connection section 32 is connected to a socket-side inner conductor 71, which is arranged in a socket-side derivation 80 of the socket connector 60, which will be described later when the plug connector 20 and the socket connector 60 are coupled together.

[0035] As this is in Fig. As illustrated in Figure 8, the connecting section of the electrical wire 33 is crimped onto and fixed to the cable core wire W1, which is exposed at a distal end of the shielded electrical wire W. In this way, the connector-side inner conductor 31 is electrically connected to the cable core wire W1 of the shielded electrical wire W. [Plug-side derivation 40]

[0036] As this is in Fig. 2 and Fig. As illustrated in Figure 3, the plug-side derivation 40 is a tubular element made of an insulating synthetic resin or plastic which has a predetermined relative dielectric constant.

[0037] The connector-side termination 40 accommodates the exposed core wire W1 and the connector-side inner conductor 31. The exposed core wire W1 extends forward from the insulator and the stranded conductor W2. The connector-side inner conductor 31 is, or will be, connected to the exposed core wire W1. The connector-side termination 40 includes a front termination 41 and a rear termination 48, which lies behind the front termination 41.

[0038] As this is in Fig. As illustrated in Figures 3 and 5 to 7, the connector-side front extension 41 has a tube-like shape, which is elongated or elongated in the forward-backward direction. The connector-side front extension 41 comprises a connector-side body section 42 and a connector-side fitting section 44, which extends forward from or through the connector-side body section 42.

[0039] The plug-side body section 42 has a circular tube shape extending in the forward-backward direction. The plug-side body section 42 can accommodate the connecting section of the electrical wire 33 of the plug-side inner conductor 31 within it.

[0040] The plug-side fitting section 44 projects forward from a front end of the plug-side body section 42.

[0041] The connector connection section 32 is inserted forward through the connector-side fitting section 44 in a forward-backward direction, so that it protrudes from the connector-side fitting section 44. The connector-side fitting section 44 has a first tapered or inclined surface 45 and a distal end surface 46.

[0042] The first tapered surface 45 is inclined to have a conical shape and is inclined closer to an axis of the plug-side fitting section 44 as it extends forward from the front end of the plug-side body section 42. The first tapered surface 45 extends around a full circumference of the plug-connect section 32 to surround the plug-connect section 32 when the plug-connect section 32 is inserted through the plug-side fitting section 44.

[0043] The distal end surface 46 is located at the anterior end section of the first tapered surface 45 and has a circular ring shape when viewed from the front, such that the distal end surface 46 extends perpendicularly to the axis of the connector-side fitting section 44. When the receiving or connector-connecting section 32 is inserted through the connector-side fitting section 44, the connector-connecting section 32 projects forward from the distal end surface 46.

[0044] As this is in Fig. As illustrated in Figure 2, the connector-side rear conductor 48 is fitted onto the outer circumference of the cable core wire W1, which is exposed by the stranded element W2 in the shielded electrical wire W and extends from it. A connector-side outer conductor 50, which will be described later, is fitted onto the outer circumference of the connector-side rear conductor 48 and pressed into place such that the connector-side rear conductor 48 is arranged around the outer circumference of the cable core wire W1 and surrounds its entire circumference. A space is provided between the cable core wire W1 and the connector-side rear conductor 48 for adjusting the impedance. [Outer conductor on the plug side 50]

[0045] The outer conductor 50 on the connector side is formed by machining an electrically conductive metal plate. How this is done in Fig. 2 and Fig. As illustrated in Figure 4, the plug-side outer conductor 50 includes a plug-side front outer conductor 51 and a plug-side rear outer conductor 58, to which the plug-side front outer conductor 51 is fitted from the outside.

[0046] The connector-side rear outer conductor 58 has a tubular shape and extends in the outer circumferential area, which ranges from the exposed stranded wire W2 to the front end section of the outer cover W3 of the shielded electrical wire W. The front section of the connector-side rear outer conductor 58 is crimped onto and fixed to the stranded wire W2 to be electrically connected to it. The rear section of the connector-side rear outer conductor 58 is crimped onto and fixed to the outer cover W3 and is also fixed to the shielded electrical wire W.

[0047] As this is in Fig. As illustrated in Figure 2, the connector-side front outer conductor 51 is a tubular element with a diameter almost equal to that of the connector-side rear outer conductor 58. The connector-side front outer conductor 51 extends in the outer circumferential region from the front end section of the connector-side rear outer conductor 58 to the middle section or cross-section of the connector-side inner conductor 31 in the forward-backward direction. The rear end section of the connector-side front outer conductor 51 is a conductor crimp section 54 of a drum shape, and the conductor crimp section 54 is crimped onto the front end section of the connector-side rear outer conductor 58. The conductor crimp section 54 is crimped onto the connector-side rear outer conductor 58 such that the connector-side front outer conductor 51 and the connector-side rear outer conductor 58 are integrally connected.are configured or constructed as a single piece, with the plug-side outer conductor 50.

[0048] The connector-side front outer conductor 51 includes a central crimp section 55 in a central section or cross-section relative to the forward-backward direction. The central crimp section 55 is crimped onto the outer circumference of the connector-side rear termination 48. The central crimp section 55 has a smaller inner diameter to avoid subjecting the connector-side rear termination 48 to excessive pressure during crimping (so that the space between the cable core wire W1 and the connector-side rear termination 48 is not reduced).

[0049] As this is in Fig. 2 and Fig. As illustrated in Figure 3, the front end section of the connector-side front outer conductor 51 is a tubular section of the connection 56, which is a circular tube. The tubular section of the connection, or connection tube section 56, is arranged to surround the outer circumferences of the connector-side front conductor 41 and the connector connection section 32, and to contain the section that extends from the rear end section of the connector-side front conductor 41 to the middle section of the connector connection section 32 in the forward-backward direction.

[0050] Therefore, as this is covered in Fig. As illustrated in Figure 2, the plug-side outer conductor 50 extends the section which extends from the middle section of the plug connection section 32 in the forward-backward direction to the front end section of the outer cover W3, while being connected to the stranded element W2 of the shielded electrical wire W. [Buckle connector 60]

[0051] As this is in Fig. 1 and Fig. As illustrated in Figure 2, the receiving or socket connector 60 includes a receiving or socket housing 61 and a receiving or socket connection module 70. [Socket housing 61]

[0052] The receiving or socket housing 61 is a tubular element made of an insulating synthetic resin or plastic. The socket housing 61 can receive the socket connection module 70 from its rear side. The socket housing 61 includes a stop, which is not illustrated. When the socket connection module 70 reaches the correct position within the socket housing 61, it stops against the stop. Thus, the socket connection module 70 is held in the socket housing 61 to prevent it from slipping out. [Socket connection module 70]

[0053] As this is in Fig. 1 and Fig. As illustrated in Figure 2, the socket connector module 70 is coupled to the plug connector module 30 when the plug connector 20 and the socket connector 60 are coupled together. Therefore, the socket connector module 70 and the plug connector module 30 are configured or constructed as a section of the connector 10. As shown in Figure 2, the socket connector module 70 and the plug connector module 30 are configured as a single section of the connector 10. Fig. As illustrated in Figure 2, the socket connection module 70 includes a socket-side inner conductor 71, a socket-side derivation 80 and a socket-side outer conductor 90. [Inner conductor on the socket side 71]

[0054] The inner conductor 71 on the socket side is formed by machining an electrically conductive metal plate. How this is done in Fig. 2, Fig. 3 and Fig. As illustrated in Figure 12, the inner conductor 71 on the socket side includes an elastic connecting section 72 and a connecting section of an electrical wire 73, which lies behind the elastic connecting section 72.

[0055] As this is in Fig. 9 and Fig. As illustrated in Figure 13, the elastic connecting section 72 comprises two elastic pieces 72A, which are positioned opposite each other. The elastic pieces 72A are elastically movable to be separated from each other. The plug connecting section 32 is inserted from a front side into a space between the elastic pieces 72A during the coupling process of the plug connector 20 and the socket connector 60. After the plug connector 20 and the socket connector 60 are coupled, as shown in Figure 13, the elastic connecting section 72 is inserted into a space between the elastic pieces 72A. Fig. As illustrated in Figure 3, the elastic pieces 72A are elastically contacted with the plug connection section 32, and the socket-side inner conductor 71 and the plug-side inner conductor 31 are electrically connected.

[0056] As this is in Fig. As illustrated in Figure 13, the connecting section of the electrical wire 73 is crimped onto and fixed to the cable core wire W1, which is exposed at a distal end of the shielded electrical wire W. In this way, the socket-side inner conductor 71 is electrically connected to the cable core wire W1 of the shielded electrical wire W. [Socket-side derivation 80]

[0057] As this is in Fig. 2 and Fig. As illustrated in Figure 3, the socket-side connection 80 is a tubular element extending in the forward-backward direction and made of an insulating synthetic resin with a predefined relative permittivity. The socket-side connection 80 receives the cable core wire W1 and the socket-side inner conductor 71 within it. The exposed cable core wire W1 extends forward from the stranded element W2. The socket-side inner conductor 71 is connected to the exposed cable core wire W1. The socket-side connection 80 includes a socket-side front connection 81 and a socket-side rear connection 87, which lies behind the socket-side front connection 81.

[0058] As this is in Fig. As illustrated in Figures 3 and 10 to 12, the bushing-side front extension 81 has a tubular shape, which is elongated or elongated in the forward-backward direction. The bushing-side front extension 81 includes a bushing-side body section 82 and a bushing-side fitting section 84.

[0059] The socket-side body section 82 has a smaller diameter in its front and rear end sections than in its middle section, relative to the forward-backward direction. The socket-side body section 82 receives the elastic connecting section 72 of the socket-side inner conductor 71 in the region extending from the front end section to the middle section, relative to the forward-backward direction. The socket-side body section 82 receives the connecting section of the electrical wire 73 of the socket-side inner conductor 71 in its rear end section. As shown in Fig. As illustrated in Figure 2, the rear end section of the socket-side body section 82 is compressed or compacted in an upward-downward direction and fixed or secured to the connection section of the electrical wire 73 by crimping a socket-side front outer conductor 91 of the socket-side outer conductor 90.

[0060] As this is in Fig. As illustrated in Figures 3 and 10 to 12, the bushing-side fitting section 84 has a circular tube shape projecting forward from the front end section of the bushing-side body section 82. The bushing-side fitting section 84 includes a recess or depression having an inner surface of a conical shape or form, such that the inner diameter of the depression decreases as the inner surface extends toward a recessed or offset bottom (rearward). Therefore, the interior of the bushing-side fitting section 84 becomes smaller as it approaches the rearward section. The inner surface of the bushing-side fitting section 84 is a second tapered surface 85, which is inclined closer to an axis of the bushing-side fitting section 84 as it extends toward the rear from the front.

[0061] The inclination angle of the second tapered surface 85 is the same as the inclination angle of the first tapered surface 45 of the connector-side fitting section 44 of the connector-side derivation 40. In this description, the configuration in which the inclination angle of the second tapered surface 85 is the same as the inclination angle of the first tapered surface 45 includes a configuration in which the inclination angle of the second tapered surface 85 is the same as the inclination angle of the first tapered surface 45, and a configuration in which the inclination angle of the second tapered surface 85 is not the same as the inclination angle of the first tapered surface 45, but is considered to be substantially the same as the inclination angle of the first tapered surface 45.

[0062] The plug-side fitting section 44 of the plug-side extension 40 is inserted into the socket-side fitting section 84 from a front side during the coupling process of the plug connector 20 and the socket connector 60. After the coupling of the plug connector 20 and the socket connector 60, as shown in Fig. 2 and Fig. As illustrated in Figure 3, the first tapered surface 45 of the plug-side mating section 44 is in close or direct contact with the second tapered surface 85 of the socket-side mating section 84 over its entire circumference. Specifically, since the first tapered surface 45 and the second tapered surface 85 are in direct contact over their entire circumferences, there is no gap or distance between them. Because the socket-side mating section 84 has a smaller volume when extending into the rear section, the space S generated in the rear section of the socket-side mating section 84 is small when the plug connector 20 and the socket connector 60 are coupled.

[0063] As this is in Fig. As illustrated in Figure 2, the socket-side rear conductor 87 is fitted to the outer circumference of the exposed cable core wire W1, which extends from the stranded element W2 into the shielded electrical wire W. A socket-side outer conductor 90, which will be described later, is fitted to the outer circumference of the socket-side rear conductor 48 and pressed in such a way that the socket-side rear conductor 87 is arranged around the outer circumference of the cable core wire W1 and surrounds the entire circumference of the cable core wire W1. A space is provided between the cable core wire W1 and the socket-side rear conductor 87 for adjusting the impedance. [Outer conductor on the socket side 90]

[0064] The outer conductor 90 on the socket side is formed by machining an electrically conductive metal plate. How this is done in Fig. 1, Fig. 2 and Fig. As illustrated in Figure 9, the socket-side outer conductor 90 includes a socket-side front outer conductor 91, a socket-side middle outer conductor 95 and a socket-side rear outer conductor 97.

[0065] The socket-side rear outer conductor 97 has a tubular shape and extends in the outer circumferential area, which ranges from the exposed stranded wire W2 to the front end section of the outer cover W3 of the shielded electrical wire W. The front section of the socket-side rear outer conductor 97 is crimped onto the stranded wire W2 and fixed thereto in order to be electrically connected to the stranded wire W2. The rear section of the socket-side rear outer conductor 97 is crimped onto the outer cover W3 and fixed to the shielded electrical wire W.

[0066] As this is in Fig. 2 and Fig. As illustrated in Figure 9, the socket-side middle outer conductor 95 is a tubular element with a diameter nearly equal to that of the socket-side rear outer conductor 97. The socket-side middle outer conductor 95 extends in the outer circumferential region from the front end section of the socket-side rear connection 87 to the front end section of the socket-side rear outer conductor 97. The front section of the socket-side middle outer conductor 95 is crimped onto the socket-side rear connection 87 to avoid subjecting the socket-side rear connection 87 to excessive pressure. The rear section of the socket-side middle outer conductor 95 is crimped onto the front section of the socket-side rear outer conductor 97 to electrically connect it to the socket-side rear outer conductor 97.

[0067] As this is in Fig. 2 and Fig. As illustrated in Figure 9, the socket-side front outer conductor 91 is a tubular element with a diameter almost equal to that of the socket-side middle outer conductor 95. The socket-side front outer conductor 91 extends in the outer circumferential region from the front end section of the socket-side middle outer conductor 95 to the front end section of the socket-side branch 80. The rear end section of the socket-side front outer conductor 91 is a tubular crimp section 92, which is crimped onto the front end section of the socket-side middle outer conductor 95 and the rear end section of the socket-side front branch 81. The tubular crimp section 92 is crimped onto the socket-side front branch 81 such that the socket-side front branch 81 is fixed to the socket-side inner conductor 71.The tubular crimp section 92 is crimped onto the socket-side middle outer conductor 95 such that the socket-side front outer conductor 91 and the socket-side middle outer conductor 95 are electrically connected. Accordingly, the socket-side front outer conductor 91, the socket-side middle outer conductor 95, and the socket-side rear outer conductor 97 are integrally configured as a single piece to form the socket-side outer conductor 90.

[0068] As this is in Fig. 2 and Fig. As illustrated in Figure 3, the front section of the socket-side front outer conductor 91, which is located on a front side relative to the middle section in the forward-backward direction, is a section of a large-diameter connection, or a large-diameter connection section 93. The section 93 of the large-diameter connection has a tubular shape and extends through the front end of the tubular crimp section 92. The section 93 of the large-diameter connection receives the front section of the socket-side front conductor 81, which is located on a front side relative to the middle section in the forward-backward direction.

[0069] Therefore, the socket-side outer conductor 90, which is connected to the stranded element W2 of the shielded electrical wire W, covers the area which extends from the elastic connecting section 72 of the socket-side inner conductor 71 to the front end section of the outer cover W3.

[0070] Namely, or in particular, are or will be, as stated in Fig. Figure 2 illustrates the plug connector 20 and the socket connector 60, which are coupled to each other, with the plug-side outer conductor 50, which has a substantially uniform diameter in the forward-backward direction, and the socket-side outer conductor 90, which has a substantially uniform diameter in the forward-backward direction.

[0071] As this is in Fig. 1 and Fig. As illustrated in Figure 9, section 93 of the large-diameter connection includes slots 93A extending in the forward-backward direction and elastic connection sections 94 located between the slots 93A. The elastic connection sections 94 are elastically deformable outwards in a radial direction.

[0072] As this is in Fig. 2 and Fig. As illustrated in Figure 3, the tubular section of the connection, or the tubular connecting section 56 of the plug-side outer conductor 50, can be inserted into a space between the section 93 of the large-diameter connection and the socket-side front lead 81. The tubular connecting section 56 is inserted into the space between the section 93 of the large-diameter connection and the socket-side front lead 81 when the plug connector 20 and the socket connector 60 are coupled together. When the tubular connecting section 56, which is inserted into the section 93 of the large-diameter connection 93, is electrically connected to the flexible connecting sections 94, the socket-side outer conductor 90 and the plug-side outer conductor 50 are electrically connected together. [Operations and advantageous effects of connector 10]

[0073] This embodiment includes the configuration and actuations described above, and the advantageous effects of the connector 10 will be described next.

[0074] In general, the characteristic impedance is set or fixed to a predefined value in order to perform impedance matching in a transmission line for the transmission of high-frequency signals.

[0075] As this is in Fig. As illustrated in Figure 15, for example, in a connector 1, which includes a receiving (socket) connector 2 and a receiving (plug) connector 6, the socket connector 2 and the plug connector 6 are coupled. The socket connector 2 includes an outer conductor 3 on the socket side, which receives an inner conductor 5 on the socket side via a socket-side lead 4. The plug connector 6 includes an outer conductor 7 on the plug side, which receives an inner conductor 9 on the plug side via a plug-side lead 8. After coupling, the socket-side lead 4 and the plug-side lead 8 are opposite each other in the coupling direction, and a plug-side inner conductor 9, which projects forward from the plug-side lead 8, is inserted into the socket-side lead 4.is connected to the inner conductor 5 on the socket side.

[0076] However, a space S may be provided between the socket-side lead 4 and the plug-side lead 8 to prevent direct contact between them, or due to manufacturing or assembly tolerances. When space S is created between the socket-side lead 4 and the plug-side lead 8, the plug-side inner conductor 9 includes an outer circumferential section where no lead 4 or 8 is present. This changes the relative dielectric constant of the section of the plug-side inner conductor 9 located within space S, and the impedance in the plug-side inner conductor becomes high. As a result, an impedance mismatch occurs in space S, and transmission signals are reflected, which can reduce transmission efficiency.

[0077] As a result of a serious review by the present inventors to solve the above problems, they have arrived at the configuration of this embodiment. This embodiment relates to the connector 10, which includes the socket terminal module 70 and the plug terminal module 30, which is to be coupled to the socket terminal module 70. The socket terminal module 70 includes the electrically conductive inner conductor 71 on the socket side, the insulating socket-side lead 80, and the electrically conductive socket-side outer conductor 90. The socket-side outer conductor 90 receives the socket-side inner conductor 71 via the socket-side lead 80. The plug terminal module 30 includes the electrically conductive plug-side inner conductor 31, the insulating plug-side lead 40, and the electrically conductive plug-side outer conductor 50. As shown in Fig. 2 and Fig. As illustrated in Figure 3, the plug-side outer conductor 50 receives the plug-side inner conductor 31 via the plug-side lead 40. The plug-side outer conductor 50 is, or becomes, connected to the socket-side outer conductor 90 when the socket connection module 70 and the plug connection module 30 are coupled together. The socket-side lead 80 includes the socket-side mating section 84, and the plug-side lead 40 includes the plug-side mating section 44.

[0078] When the socket connection module 70 and the plug connection module 30 are coupled together, as shown in Fig. 2 and Fig. As illustrated in Figure 3, the socket-side fitting section 84 and the plug-side fitting section 44 are fitted together with a recess and protrusion in the coupling direction in which the socket connection module 70 and the plug connection module 30 are coupled. The plug-side inner conductor 31 includes the plug connection section 32, and the plug connection section 32 extends further forward than the plug-side fitting section 44 and towards the socket connection module 70. When the socket connection module 70 and the plug connection module 30 are coupled together, as shown in Figure 3, the socket connection module 70 and the plug connection module 30 are connected. Fig. As illustrated in Figure 2, the plug connection section 32 is inserted into the socket-side fitting section 84 and connected to the socket-side inner conductor 71.

[0079] According to this embodiment, when the plug-connection section 32, which projects from the plug-side fitting section 44, is inserted into the socket-side fitting section 84 and connected to the socket-side inner conductor 71 after coupling the socket connection module 70 and the plug connection module 30, the socket-side fitting section 84 and the plug-side fitting section 44 are fitted to each other in the coupling direction with the fitting of a recess and protrusion.

[0080] Therefore, at least the plug-side fitting section 44 or the socket-side fitting section 84 is arranged around the plug-connection section 32. Accordingly, the relative dielectric constant is less likely to change in the plug-connection section 32, thus maintaining a small impedance change. Therefore, the reflection loss of high-frequency signals can be minimized, and the transmission efficiency is less likely to be reduced in the connector 10.

[0081] The plug-side mating section 44, which is one of the socket-side mating sections 84 and the plug-side mating section 44, is a raised or projecting element that includes the first tapered surface 45. The socket-side mating section 84, which is another of the mating sections, is a recessed or offset element that has the second tapered surface 85. The first tapered surface 45 is inclined closer to the axis of the plug-connection section 32 as it extends forward (toward the other mating section), and the second tapered surface 85 is inclined closer to the axis of the plug-connection section 32 as it extends away from the plug-side mating section 44, and the second tapered surface 85 extends along the first tapered surface 45.

[0082] Generally, a gap is provided between a distal end of the plug-side mating section and a distal end of the socket-side mating section in a section where the plug connection section is inserted into the socket-side mating section. This prevents the distal end of the plug-side mating section from contacting or striking the distal end of the socket-side mating section in the coupling direction, thus ensuring proper mating of the mating sections.

[0083] For example, if one mating section of the plug-side mating section and the socket-side mating section has a circular, columnar shape, and another mating section of the mating sections has a circular, columnar recess, the space created around the outer circumference of the connector near a recessed bottom of the recess has a diameter that is the same as the inner diameter of the recess. Therefore, the impedance change tends to be large in the connector.

[0084] However, according to this embodiment, the plug-side fitting section 44, which is one fitting section, is the raised or projecting member which includes the first tapered or inclined surface 45, and the socket-side fitting section 84, which is the other fitting section, is the recessed or offset member which includes the second tapered surface 85.

[0085] In particular, or rather, it shows how this is in Fig. As illustrated in Figure 3, the socket-side fitting section 84, which is the recessed or offset element, has an inner space that decreases as it approaches the recessed base. This reduces the space S around the outer circumference of the connector connection section 32 near the recessed base of the socket-side fitting section 84. Consequently, the impedance change in the connector connection section 32 can be significantly reduced, and the reflection loss of high-frequency signals in the connector connection section 32 can be further lowered.

[0086] As this is in Fig. 5, Fig. 6 to Fig. As illustrated in Figure 7, the first tapered surface 45° is inclined and formed in a conical shape, tapering towards a distal end. As shown in Fig. 10, Fig. 11 to Fig. As illustrated in Figure 12, the second tapered surface 85 extends to form a conical shape, the diameter of which is reduced as or when it extends towards the recessed bottom of the depression.

[0087] In particular, the socket-side fitting section 84, which is the recessed element, has a smaller space around the plug-connection section 32 and near the recessed bottom due to the second tapered surface 85. Therefore, as shown in Fig. As illustrated in Figure 3, the space between the plug-side mating section 44 and the socket-side mating section 84 can be made smaller compared to a configuration that includes a second tapered surface in a section of the socket-side mating section. Accordingly, the impedance loss can be made much smaller and the reflection loss of high-frequency signals can be further reduced.

[0088] As this is in Fig. As illustrated in Figure 3, the first tapered surface 45 and the second tapered surface 85 are in close or direct contact with each other when the socket connector module 70 and the plug connector module 30 are coupled together. In particular, the direct contact between the first tapered surface 45 and the second tapered surface 85 reduces the space between the socket-side fitting section 84 and the plug-side fitting section 44. Consequently, the impedance change can be significantly reduced, and the reflection loss of high-frequency signals can be further minimized.

[0089] As described above, according to this embodiment, at least the socket-side lead 80 or the plug-side lead 40 is arranged around the outer circumference of the plug-connection section 32, and a small space is provided between the plug-side fitting section 44 and the socket-side fitting section 84. Specifically, in this embodiment, the impedance change in the plug-connection section 32 can be suppressed to be small, the reflection loss of high-frequency signals can be reduced, and the transmission efficiency is less likely to be lowered. <Andere Ausführungsformen>

However, a shielded electrical wire may comprise several cable core wires, and a plug-side termination may comprise several plug-side mating sections, and a socket-side termination may comprise several socket-side mating sections.

[0092] (2) In the above embodiment, the socket-side lead 80 includes two leads and the plug-side lead 40 includes two leads. However, each of the socket-side lead and the plug-side lead can include a single lead.

[0093] (3) In the above embodiment, the socket-side outer conductor 90 comprises three outer conductors and the plug-side outer conductor 50 comprises two outer conductors. However, each of the socket-side outer conductor and the plug-side outer conductor may comprise a single outer conductor.

[0094] (4) In the above embodiment, the socket-side fitting section 44, which projects in a conical shape and includes the first tapered surface, and the socket-side fitting section 84, which includes a conical recess and the second tapered surface 85, are fitted to one another by a recess and protrusion in the forward-backward direction. However, a socket-side fitting section may project in a conical shape, and a plug-side fitting section may include a conical recess. The socket-side fitting section may include a recess having a polygonal pyramidal shape, and the plug-side fitting section may have a protrusion having a polygonal pyramidal shape.

[0095] As this is in Fig.Figure 14, which represents a non-inventive embodiment, illustrates that a plug-side extension 140 can include a plug-side fitting section 144, which has a protrusion or projection of a circular column-like shape, and a socket-side extension 180 can include a socket-side fitting section 184, which has a recess or indentation of a circular column-like shape. The plug-side fitting section 144 and the socket-side fitting section 184 can be fitted to one another with a recess and protrusion in the forward-backward direction. In such a configuration, even if a first tapered surface and a second tapered surface are not fully in contact with each other, a space between the first tapered surface and the second tapered surface can be uniformly filled.It will be uniform and it is less likely that a local change in impedance will be caused.
