DETAILED DESCRIPTION

[0032] The L-shaped coaxial connector 10 according to the present disclosure is described below with reference to the accompanying drawings. For ease of explanation, the figures illustrate orthogonal X-axis, Y-axis, and Z-axis directions. The X-axis direction indicates the direction in which the coaxial cable 40 extends. The Z-axis direction indicates the direction in which the housing 16, bushing 12, and socket 14 overlap in the L-shaped coaxial connector 10 and is the direction in which the L-shaped coaxial connector 10 is inserted and removed from the mating connector 20. The Y-axis direction is orthogonal to the X-axis and Z-axis directions.

[0033] 〔Coaxial connector assembly〕

[0034] Figure 1 2 is a perspective view of the coaxial connector assembly 1 according to the present disclosure.

[0035] like Figure 1 As shown, the coaxial connector assembly 1 includes an L-shaped coaxial connector (coaxial connector) 10 and a counterpart connector 20. The L-shaped coaxial connector 10 is configured to be pluggable and removable with respect to the counterpart connector (receptacle) 20 in the Z-axis direction. Figure 1In the illustrated coaxial connector assembly 1, the L-shaped coaxial connector 10 and the mating connector 20 are positioned facing each other, and the mating connector 20 is moved in the Z-axis direction toward the mating connector 20, thereby mating the L-shaped coaxial connector 10 and the mating connector 20. The L-shaped coaxial connector 10 is connected to the coaxial cable 40 by riveting, while the mating connector 20 is mounted on a circuit board (not shown).

[0036] Coaxial cable

[0037] like Figure 9 As shown, the coaxial cable 40 connected to the L-shaped coaxial connector 10 is composed of a center conductor 41, an insulator 42, an outer conductor 43, and an outer coating 44. As the center conductor 41, for example, a single wire or a stranded wire made of soft copper, tinned soft copper, copper alloy, aluminum, aluminum alloy, CP wire (copper-clad iron wire), etc. can be used.

[0038] Insulator 42 is provided around center conductor 41. Insulator 42 is made of a resin material, such as polymethylpentene, having a relative dielectric constant of 2 to 2.3 and a Rockwell hardness of 50 to 100. This material has a high hardness, making it resistant to deformation caused by riveting and preventing a negative impact on characteristic impedance. The Rockwell hardness (HR) in this disclosure is measured according to the method specified in ASTM-D785, and the measured value is expressed on the R scale.

[0039] The outer conductor 43 is provided around the insulator 42. As the outer conductor 43, for example, a structure having a metal layer on the outer periphery of soft copper, tin-plated soft copper, aluminum alloy, or synthetic resin fiber can be used.

[0040] The outer coating 44 is provided around the outer conductor 43. The outer coating 44 may be made of, for example, vinyl chloride resin, fluororesin, polyethylene, polypropylene, olefin resin such as propylene-ethylene copolymer, ethylene-propylene rubber, butadiene rubber or the like.

[0041] like Figure 7 As shown, at the end of the coaxial cable 40, the outer coating 44 is removed to expose the outer conductor 43. Also, at the end of the coaxial cable 40, the outer conductor 43 is removed to expose the insulator 42.

[0042] [Connector on the other side]

[0043] like Figure 1 As shown, the counterpart connector 20 includes a counterpart internal terminal (center pin) 24 , a counterpart external terminal 26 , and a counterpart insulating member (resin mold) 22 disposed between the counterpart internal terminal 24 and the counterpart external terminal 26 .

[0044] The counterpart internal terminal 24 is connected to a signal pad portion of a circuit board (not shown) and is electrically insulated from the counterpart external terminal 26 by the counterpart insulating member 22 .

[0045] The mating internal terminal 24 is formed from a conductive member, such as a single metal plate made of a copper alloy. Nickel and gold plating is applied to the surface of the mating internal terminal 24. The mating internal terminal 24 is integrated with the mating insulating member 22, for example, by insert molding. This structure allows for accurate positioning of the mating insulating member 22 and the mating internal terminal 24.

[0046] The counterpart internal terminal 24 includes a counterpart internal contact portion 24a and a counterpart internal mounting portion (not shown). The counterpart internal terminal 24 is bent in an L-shape in cross-sectional view.

[0047] The mating internal contact portion 24a extends in the Z-axis direction and is formed into a generally cylindrical male (pin-shaped) shape. The mating internal contact portion 24a contacts the internal contact portion 14a of the internal terminal 14 of the L-shaped coaxial connector 10, thereby forming an electrical connection. The mating internal mounting portion is electrically connected to a signal pad portion of a circuit board (not shown) via a conductive member such as solder.

[0048] The mating external terminal 26 is connected to a ground pad on the circuit board (not shown). The mating external terminal 26 is made of a conductive member, for example, a single metal plate such as a copper alloy. Nickel and gold plating is applied to the surface of the mating external terminal 26. The mating external terminal 26 is integrated with the mating insulating member 22 by insert molding. This structure allows for accurate positioning of the mating insulating member 22 and the mating external terminal 26.

[0049] The counterpart external terminal 26 includes a counterpart external mounting portion 26a and a counterpart second external connecting portion 26b. The counterpart external mounting portion 26a is electrically connected to a ground pad portion of a circuit board (not shown) via a conductive member such as solder.

[0050] The second external connection portion 26b on the other side is generally cylindrical and extends in the Z-axis direction. It is coaxially arranged with the internal contact portion 24a on the other side. The second external connection portion 26b on the other side contacts the second external connection portion 16b of the external terminal 16 of the L-shaped coaxial connector 10, thereby forming an electrical connection. A mating recess 26h is formed on the outer peripheral surface of the second external connection portion 26b on the other side. When the L-shaped coaxial connector 10 is mated to the mating connector 20, the mating recess 26h of the second external connection portion 26b on the other side engages with the mating protrusion 16h of the second external connection portion 16b.

[0051] L-shaped coaxial connector

[0052] like Figures 2 to 8 As shown, the L-shaped coaxial connector 10 includes an insulating member (bushing) 12 , an internal terminal (socket) 14 , and an external terminal (housing) 16 .

[0053] The internal terminal 14 is connected to the central conductor 41 of the coaxial cable 40 . The internal terminal 14 is electrically insulated from the external terminal 16 by the insulating member 12 .

[0054] Internal terminal 14 is made of a conductive member, such as a single metal plate made of a copper alloy. Nickel and gold plating is applied to the surface of internal terminal 14. Internal terminal 14 is integrated with insulating member 12 through insert molding. This structure allows for accurate positioning of insulating member 12 and internal terminal 14. Details of internal terminal 14 will be described below.

[0055] like Figure 7 As shown, the external terminal 16 is connected to the external conductor 43 of the coaxial cable 40. The external terminal 16 is made of a conductive member, for example, a single metal plate such as a copper alloy material. The surface of the external terminal 16 is plated with nickel and gold.

[0056] The external terminal 16 includes a base portion 16a, a cylindrical portion (second external connection portion) 16d, and a connecting portion 16f. The base portion 16a and the cylindrical portion (second external connection portion) 16d are connected by the connecting portion 16f provided on the side opposite to the side where the coaxial cable 40 is arranged.

[0057] The cylindrical portion (second external connection portion) 16d extends in the Z-axis direction and, when viewed from the Z-axis direction, forms an arc shape formed by forming a notch in a portion of the circumferential shape on the side close to the coaxial cable 40 (the opposite side of the connecting portion 16f). When viewed from the Z-axis direction, the cylindrical portion 16d has an opening on the side where the coaxial cable 40 is provided, that is, on the side opposite to the connecting portion 16f. The mating protrusion 16h of the cylindrical portion 16d is configured to mate with the mating recess 26h of the counterpart external terminal 26 of the counterpart connector 20. The internal insulating portion 12a of the insulating member 12 passes through the opening of the cylindrical portion 16d and is inserted into the cylindrical portion 16d to form an assembly. The internal contact portion 14a of the internal terminal 14 is located on the inner side of the cylindrical portion 16d. At this time, the cylindrical portion 16d is positioned coaxially with the internal contact portion 14a.

[0058] The base portion 16a has a plate shape extending from the connecting portion 16f in the X-axis direction. In the assembled state, the base portion 16a is positioned along the upper surfaces of the insulating member 12 and the coaxial cable 40 to hold the insulating member 12 and the coaxial cable 40.

[0059] The base portion 16a includes, in order from the cylindrical portion (second external connection portion) 16d side, a caulking engagement portion (first external connection portion) 16c, an external conductor caulking portion 16s, and an external covering caulking portion 16t.

[0060] Although details will be described below, the caulking engagement portion 16c is caulked while surrounding the insulator 42 of the coaxial cable 40, thereby electrically connecting the internal terminal 14 to the center conductor 41 of the coaxial cable 40. The outer conductor caulking portion 16s is caulked while surrounding the outer conductor 43 of the coaxial cable 40, thereby electrically connecting to the outer conductor 43. The outer sheath caulking portion 16t is caulked while surrounding the electrically insulating outer sheath 44 of the coaxial cable 40, thereby being fixed to the outer sheath 44.

[0061] The insulating member 12 is disposed between the internal terminal 14 and the external terminal 16. The insulating member 12 is made of an electrically insulating resin (eg, liquid crystal polymer) and electrically insulates the internal terminal 14 and the external terminal 16 from each other.

[0062] The insulating member 12 can be made of a resin material having a relative dielectric constant of 2 to 2.3 and a Rockwell hardness of 50 to 100. This prevents deformation of the insulating member 12 when the L-shaped coaxial connector 10 is riveted to the coaxial cable 40. Therefore, even with relatively low riveting force, the first mounting portion 14f and the second mounting portion 14m can retain the center conductor 41. The resin material comprising the insulating member 12 is, for example, polymethylpentene. This allows the insulating member 12 to be easily formed even with a complex shape.

[0063] like Figure 7 As shown, the insulating member 12 includes an inner insulating portion 12a, a central conductor holding portion 12b, and an insulating connecting portion 12d. The inner insulating portion 12a and the central conductor holding portion 12b of the insulating member 12 are configured to branch into two branches in the Y-axis direction starting from the insulating connecting portion 12d and can be opened and closed.

[0064] When viewed from the Z-axis, the internal insulating portion 12a is approximately circular in the closed position and approximately semicircular in the open position. The internal insulating portion 12a is sized to fit within the opening of the cylindrical portion 16d and fit within the cylindrical portion 16d in the Z-axis direction. Within the internal insulating portion 12a, the internal contact portion 14a of the internal terminal 14 bulges out in the Z-axis direction. The internal contact portion 14a is coaxial with the internal insulating portion 12a.

[0065] The center conductor holding portion 12b extends from the internal insulating portion 12a toward the coaxial cable 40 in the general X-axis direction. When viewed from the Z-axis direction, the center conductor holding portion 12b has a generally rectangular shape. The center conductor holding portion 12b includes a receiving recess 12c. The receiving recess 12c is configured to accommodate the connecting arm portions 14b and 14c and the mounting portions 14f and 14m of the internal terminal 14.

[0066] [Implementation Method 1]

[0067] In the L-shaped coaxial connector 10 according to the first embodiment, Figure 7 As shown, the internal terminal 14 includes an internal contact portion 14a, a first connecting arm portion 14b, a second connecting arm portion 14c, a first mounting portion 14f, and a second mounting portion 14m. The internal contact portion 14a is connected to the first connecting arm portion 14b and the second connecting arm portion 14c via a connecting portion 14d.

[0068] The internal contact portion 14a is female (socket-shaped), extends in the Z-axis direction, and has a substantially C-shaped shape with a partially notched circumferential portion. The internal contact portion 14a electrically contacts the mating internal contact portion 24a of the mating internal terminal 24 of the mating connector 20.

[0069] The internal terminal 14 is divided into two branches, namely the first connecting arm portion 14b and the second connecting arm portion 14c, with the connecting portion 14d as the base point. The first connecting arm portion 14b and the second connecting arm portion 14c are arranged to face each other in the Y-axis direction. The first connecting arm portion 14b and the second connecting arm portion 14c are configured to be movable along the surface (i.e., the XY plane) on which the base portion 16a of the external terminal 16 extends, with the connecting portion 14d as the fulcrum. As a result, the dimension of the internal terminal 14 in the Z-axis direction, which is orthogonal to the surface on which the base portion 16a extends, i.e., the dimension of the internal terminal 14 in the height direction, becomes smaller, thereby enabling the L-shaped coaxial connector 10 to be made low-profile.

[0070] The first connecting arm portion 14b and the second connecting arm portion 14c are plate-shaped portions extending generally in the X-axis direction. In the X-axis direction, the first connecting arm portion 14b is longer than the second connecting arm portion 14c. The first connecting arm portion 14b has a first mounting portion 14f midway toward the coaxial cable 40. The first mounting portion 14f is bent in an L-shape toward the second connecting arm portion 14c and extends generally in the Y-axis direction. This allows the movement of the first connecting arm portion 14b to facilitate insertion of the first mounting portion 14f into the coaxial cable 40.

[0071] The first mounting portion 14f has a U-shaped portion formed at its distal end. Specifically, the first mounting portion 14f has a first slit 14g formed therein. The first slit 14g is configured to receive the center conductor 41 of the coaxial cable 40.

[0072] The second connecting arm 14c includes a second mounting portion 14m midway toward the coaxial cable 40. The second mounting portion 14m bends in an L-shape toward the first connecting arm 14b and extends substantially in the Y-axis direction. This allows the movement of the second connecting arm 14c to be utilized for inserting the second mounting portion 14m into the coaxial cable 40.

[0073] The second mounting portion 14m has a U-shaped notch formed at the distal end thereof. Specifically, the second mounting portion 14m has a second slit 14n formed therein. The second slit 14n is configured to receive the center conductor 41 of the coaxial cable 40.

[0074] When viewed from the direction in which the coaxial cable 40 extends (i.e., the axial direction of the coaxial cable 40, i.e., the X-axis direction), the first mounting portion 14f and the second mounting portion 14m face each other. Thus, the first mounting portion 14f and the second mounting portion 14m can clamp the center conductor 41 of the coaxial cable 40. Furthermore, the angle formed between the first mounting portion 14f and the second mounting portion 14m is 180 degrees. Thus, the first mounting portion 14f and the second mounting portion 14m can clamp the center conductor 41 of the coaxial cable 40 from both sides.

[0075] The first mounting portion 14f is located closer to the coaxial cable 40 than the second mounting portion 14m. In other words, the first mounting portion 14f and the second mounting portion 14m are positioned differently in the direction of extension of the coaxial cable 40 (i.e., in the X-axis direction). Furthermore, due to the staggered arrangement of the first slit 14g and the second slit 14n in the extension direction, the center conductor 41 of the coaxial cable 40 is free to bend and plastically deform. This allows the first mounting portion 14f and the second mounting portion 14m to clamp the center conductor 41 of the coaxial cable 40 at different locations.

[0076] The caulking engagement portion 16c extends from the side end portion of the base portion 16a in the Z-axis direction. The caulking engagement portion 16c is composed of a pair of plate-shaped portions formed to face each other in the Y-axis direction.

[0077] By bending and riveting the rivet engagement portion 16c, the first connecting arm 14b and the second connecting arm 14c of the internal terminal 14 move closer together in the Y-axis direction, forcibly pressing the insulator 42 of the coaxial cable 40 against the first mounting portion 14f and the second mounting portion 14m of the internal terminal 14. The first mounting portion 14f and the second mounting portion 14m each form a notch in the insulator 42 of the coaxial cable 40, forcing the center conductor 41 into the first slit 14g and the second slit 14m, thereby exposing the center conductor 41 covered by the insulator 42. The exposed center conductor 41 is inserted into the first slit 14g and the second slit 14m, contacting the first mounting portion 14f and the second mounting portion 14m. This electrically connects the first mounting portion 14f to the center conductor 41 at the first connection point, and the second mounting portion 14m to the center conductor 41 at the second connection point.

[0078] like Figure 8 As shown, the first mounting portion 14f and the second mounting portion 14m have different positions in the extension direction of the coaxial cable 40 (i.e., the positions in the X-axis direction). Therefore, the first mounting portion 14f and the second mounting portion 14m are electrically connected to the center conductor 41 at two different connection positions, namely the first connection position and the second connection position.

[0079] Therefore, two different connection positions are provided, namely a first connection position between the center conductor 41 and the first mounting portion 14f and a second connection position between the center conductor 41 and the second mounting portion 14m, thereby achieving connection redundancy. Therefore, the connection stability between the center conductor 41 of the coaxial cable 40 and the mounting portions 14f and 14m of the internal terminal 14 can be improved.

[0080] [Implementation Method 2]

[0081] Reference Figure 10 and Figure 11 The internal terminal 14 and the insulating member 12 of the L-shaped coaxial connector 10 according to the second embodiment will be described.

[0082] like Figure 10 As shown, in the internal terminal 14, the first connecting arm portion 14b and the second connecting arm portion 14c are configured to be movable in the Z-axis direction with the connecting portion 14d as a fulcrum. The structure of the insulating member 12 is modified to match this internal terminal 14. The following description focuses on the differences from the L-shaped coaxial connector 10 according to the first embodiment described above.

[0083] like Figure 10As shown, the internal terminal 14 includes an internal contact portion 14a, a first connecting arm portion 14b, a second connecting arm portion 14c, a first mounting portion 14f, and a second mounting portion 14m. The internal contact portion 14a is connected to the second connecting arm portion 14c, and the first connecting arm portion 14b is connected to the second connecting arm portion 14c via a connecting portion 14d.

[0084] The internal contact portion 14a extends in the Z-axis direction and is formed into a substantially C-shaped female (socket-type) with a partially notched circumferential portion. The internal contact portion 14a electrically contacts the counterpart internal contact portion 24a of the counterpart internal terminal 24 of the counterpart connector 20.

[0085] The internal terminal 14 is divided into two branches, a first connecting arm 14b and a second connecting arm 14c, with the connecting portion 14d as the base point. The first connecting arm 14b and the second connecting arm 14c are arranged to face each other in the Z-axis direction. The first connecting arm 14b and the second connecting arm 14c are configured to be movable in the Z-axis direction with the connecting portion 14d as the fulcrum.

[0086] The first connecting arm portion 14b and the second connecting arm portion 14c are plate-shaped portions extending generally in the X-axis direction. The first connecting arm portion 14b is longer in the X-axis direction than the second connecting arm portion 14c. The first connecting arm portion 14b has a first mounting portion 14f midway toward the coaxial cable 40. The first mounting portion 14f is bent in an L-shape toward the second connecting arm portion 14c and extends generally in the Y-axis direction. This allows the movement of the first connecting arm portion 14b to facilitate insertion of the first mounting portion 14f into the coaxial cable 40.

[0087] The first mounting portion 14f has a U-shaped portion formed at the distal end thereof. Specifically, the first mounting portion 14f has a first slit 14g formed therein. The first slit 14g is configured to receive the center conductor 41 of the coaxial cable 40.

[0088] The second connecting arm 14c includes a second mounting portion 14m midway toward the coaxial cable 40. The second mounting portion 14m bends in an L-shape toward the first connecting arm 14b and extends substantially in the Y-axis direction. This allows the movement of the second connecting arm 14c to be utilized for inserting the second mounting portion 14m into the coaxial cable 40.

[0089] The second mounting portion 14m has a U-shaped notch formed at the distal end thereof. Specifically, the second mounting portion 14m has a second slit 14n formed therein. The second slit 14n is configured to receive the center conductor 41 of the coaxial cable 40.

[0090] When viewed from the direction in which the coaxial cable 40 extends (i.e., the axial direction of the coaxial cable 40, i.e., the X-axis direction), the first mounting portion 14f and the second mounting portion 14m face each other. Thus, the first mounting portion 14f and the second mounting portion 14m can clamp the center conductor 41 of the coaxial cable 40. Furthermore, the angle formed between the first mounting portion 14f and the second mounting portion 14m is 180 degrees. Thus, the first mounting portion 14f and the second mounting portion 14m can clamp the center conductor 41 of the coaxial cable 40 from both sides.

[0091] The first mounting portion 14f is located closer to the coaxial cable 40 than the second mounting portion 14m. In other words, the first mounting portion 14f and the second mounting portion 14m are positioned differently in the direction of extension of the coaxial cable 40 (i.e., in the X-axis direction). Furthermore, due to the offset arrangement of the first slit 14g and the second slit 14n in the extension direction, the center conductor 41 of the coaxial cable 40 is free to bend and plastically deform. Consequently, the first mounting portion 14f and the second mounting portion 14m can clamp the center conductor 41 of the coaxial cable 40 at different positions.

[0092] Insulating member 12 includes a central conductor holding portion 12b having an internal insulating portion 12a and corresponding to second connecting arm portion 14c, and a central conductor holding portion 12b corresponding to first connecting arm portion 14b, which are formed separately. The central conductor holding portion 12b includes a receiving recess 12c configured to accommodate second connecting arm portion 14c and second mounting portion 14m. The central conductor holding portion 12b includes a receiving recess 12c configured to accommodate first connecting arm portion 14b and first mounting portion 14f.

[0093] The rivet engagement portion 16c of the external terminal 16 is bent and riveted, causing the first and second connecting arms 14b, 14c of the internal terminal 14 to move closer together in the Z-axis direction, forcibly pressing the coaxial cable 40 against the first and second mounting portions 14f, 14m of the internal terminal 14. The first and second mounting portions 14f, 14m each form cutouts in the insulator 42 of the coaxial cable 40, forcing the center conductor 41 into the first and second slits 14g, 14n, respectively. This exposes the center conductor 41, previously covered by the insulator 42. The exposed center conductor 41 is inserted into the first and second slits 14g, 14n, and contacts the first and second mounting portions 14f, 14m. This electrically connects the first mounting portion 14f to the center conductor 41 at the first connection point, and the second mounting portion 14m to the center conductor 41 at the second connection point.

[0094] like Figure 11As shown, the first mounting portion 14f and the second mounting portion 14m have different positions in the extension direction of the coaxial cable 40 (i.e., the positions in the X-axis direction). Therefore, the first mounting portion 14f and the second mounting portion 14m are electrically connected to the center conductor 41 at two different connection positions, namely the first connection position and the second connection position.

[0095] Therefore, two different connection positions are provided, namely a first connection position between the center conductor 41 and the first mounting portion 14f and a second connection position between the center conductor 41 and the second mounting portion 14m, thereby achieving connection redundancy. Therefore, the connection stability between the center conductor 41 of the coaxial cable 40 and the mounting portions 14f and 14m of the internal terminal 14 can be improved.

[0096] [Implementation Method 3]

[0097] Reference Figure 12 and Figure 13 The internal terminal 14 and the insulating member 12 of the L-shaped coaxial connector 10 according to the third embodiment will be described.

[0098] like Figure 12 and Figure 13 As shown, in the internal terminal 14, the first connecting arm portion 14b has a first mounting portion 14f and a second mounting portion 14m at different positions in the extending direction of the coaxial cable 40, and the first slit 14g is configured such that the first direction A1 and the second slit 14n are different in the second direction A2. The structure of the insulating member 12 is modified to match this internal terminal 14. The following description focuses on the differences from the L-shaped coaxial connector 10 according to the first embodiment described above.

[0099] like Figure 12 As shown, the internal terminal 14 includes an internal contact portion 14a, a first connecting arm portion 14b, a first mounting portion 14f, and a second mounting portion 14m. The internal contact portion 14a is connected to the first connecting arm portion 14b.

[0100] The first connecting arm portion 14b is a plate-shaped portion extending generally in the X-axis direction. The first connecting arm portion 14b has a first mounting portion 14f and a second mounting portion 14m midway toward the coaxial cable 40. The first mounting portion 14f is located closer to the coaxial cable 40 than the second mounting portion 14m. In other words, the first mounting portion 14f and the second mounting portion 14m are located at different positions in the direction in which the coaxial cable 40 extends, that is, in the X-axis direction.

[0101] The first mounting portion 14f and the second mounting portion 14m bend in an L-shape from the first connecting arm portion 14b and extend generally upward in the Z-axis direction. The distal end of the first mounting portion 14f is notched, giving the first mounting portion 14f a U-shape. Specifically, a first slit 14g is formed in the first mounting portion 14f. The first slit 14g is configured to receive the center conductor 41 of the coaxial cable 40 and extends in the first direction A1.

[0102] The second mounting portion 14m has a U-shaped notch formed at its distal end. Specifically, the second mounting portion 14m has a second slit 14n formed therein. The second slit 14n is configured to receive the center conductor 41 of the coaxial cable 40 and extends in the second direction A2.

[0103] like Figure 13 As shown, the first direction A1 of the first slit 14g relative to the first connecting arm portion 14b is different from the second direction A2 of the second slit 14n relative to the first connecting arm portion 14b. For example, the first slit 14g is inclined to the right relative to the first connecting arm portion 14b, and the second slit 14n is inclined to the left relative to the first connecting arm portion 14b. The offset angle a formed by the first direction A1 and the second direction A2 is, for example, greater than 1 degree and less than 15 degrees, preferably greater than 2 degrees and less than 10 degrees. In other words, the first mounting portion 14f and the second mounting portion 14m are arranged at an offset angle relative to the first connecting arm portion 14b. Moreover, corresponding to the arrangement of the first slit 14g and the second slit 14n at the offset angle, the center conductor 41 of the coaxial cable 40 is free to bend and plastically deform. Thus, the center conductor 41 of the coaxial cable 40 can be smoothly inserted into each of the first slit 14g and the second slit 14n, and the first mounting portion 14f and the second mounting portion 14m can clamp the center conductor 41 of the coaxial cable 40 at different positions.

[0104] In the insulating member 12, one central conductor holding portion 12b, which includes a semi-cylindrical inner insulating portion 12a, and another central conductor holding portion 12b, which also includes a semi-cylindrical inner insulating portion 12a, are connected by an insulating connecting portion 12d. Each of the first and second central conductor holding portions 12b, 12b, has a receiving recess 12c configured to accommodate the first connecting arm portion 14b, the first mounting portion 14f, and the second mounting portion 14m. The receiving recess 12c is open upward in the Z-axis direction, exposing the first mounting portion 14f and the second mounting portion 14m.

[0105] The rivet engagement portion 16c of the external terminal 16 is bent and rivet-engaged, forcibly pressing the coaxial cable 40 against the first mounting portion 14f and the second mounting portion 14m of the internal terminal 14. The first mounting portion 14f and the second mounting portion 14m are formed by cutting into the insulator 42 of the coaxial cable 40 and pressing the center conductor 41 into the first slit 14g and the second slit 14n, respectively. This exposes the center conductor 41, which is covered by the insulator 42. The exposed center conductor 41 is inserted into the first slit 14g and the second slit 14n and contacts the first mounting portion 14f and the second mounting portion 14m. This electrically connects the first mounting portion 14f to the center conductor 41 at the first connection point, and the second mounting portion 14m to the center conductor 41 at the second connection point.

[0106] like Figure 13 As shown, the first slit 14g extends in a first direction A1 that is different from the second direction A2 that is different from the second slit 14n. As a result, the first mounting portion 14f and the second mounting portion 14m are electrically connected to the center conductor 41 at two different connection locations, namely the first connection location and the second connection location, achieving connection redundancy. This improves the connection stability between the center conductor 41 and the first mounting portion 14f and the second mounting portion 14m.

[0107] Therefore, two different connection positions are provided, namely a first connection position between the center conductor 41 and the first mounting portion 14f and a second connection position between the center conductor 41 and the second mounting portion 14m, thereby achieving connection redundancy. Therefore, the connection stability between the center conductor 41 of the coaxial cable 40 and the mounting portions 14f and 14m of the internal terminal 14 can be improved.

[0108] Although specific embodiments of the present disclosure have been described, the present disclosure is not limited to the above-described embodiments and can be implemented with various modifications within the scope of the present disclosure.

[0109] In the above-described embodiment, a resin material (e.g., polymethylpentene) having a relative dielectric constant of 2 to 2.3 and a Rockwell hardness of 50 to 100 is exemplified as the insulating member 12 and the insulator 42. However, for example, a porous body or foam made of a vinyl chloride resin such as polyvinyl chloride, or an olefin resin such as polyethylene, polypropylene, or a propylene-ethylene copolymer may be used as the insulating member 12 and the insulator 42.

[0110] In the above-described embodiment, the internal terminal 14 is shown as having multiple mounting portions, namely, a first mounting portion 14f and a second mounting portion 14m. However, to further achieve connection redundancy, the internal terminal 14 may also have three or more mounting portions. For example, in Embodiments 1 and 2, the first connecting arm 14b may also have a third mounting portion on the side of the second connecting arm 14c's second mounting portion 14m closer to the insulating coupling portion 12d. Furthermore, in Embodiments 1 and 2, in addition to the third mounting portion, the second connecting arm 14c may also have a fourth mounting portion on the side of the third mounting portion of the first connecting arm 14b closer to the insulating coupling portion 12d. Therefore, in Embodiments 1 and 2, the positions of the first mounting portion 14f, the second mounting portion 14m, the third mounting portion, and the fourth mounting portion in the direction in which the coaxial cable 40 extends may be different.

[0111] Furthermore, in the third embodiment, the first connecting arm portion 14b may further include a third mounting portion on the side of the insulating coupling portion 12d relative to the second mounting portion 14m, comprising a third slit extending in the same direction A1 as the first slit 14g. Furthermore, in the third embodiment, the first connecting arm portion 14b may further include a fourth mounting portion on the side of the insulating coupling portion 12d relative to the third mounting portion, comprising a fourth slit extending in the same direction A2 as the second slit 14n. Therefore, in the third embodiment, the first direction A1 of the first slit 14g, the second direction A2 of the second slit 14n, the third direction of the third slit, and the fourth direction of the fourth slit may all be different.

[0112] In the third embodiment, the first slit 14g is exemplified as follows: Figure 13 The second direction A2 of the second slit 14n is tilted to the right side and directed Figure 13 However, as long as the first direction A1 and the second direction A2 do not point to the same direction, they may also point to the left. Figure 13 In addition, it can also be that either the first direction A1 or the second direction A2 is tilted at a different angle to point to the right or left side. Figure 13 Point in the Z direction and any other direction Figure 13 Tilt to either the right or left side while pointing this way.

[0113] In the first and third embodiments, the two internal insulating portions 12a, 12a constituting the insulating member 12 are connected by the insulating connecting portion 12d, but the two internal insulating portions 12a, 12a can be configured as separate and independent components. In the second embodiment, the insulating member 12 has two separate and independent internal insulating portions 12a, 12a, but the two internal insulating portions 12a, 12a can also be configured as being connected by the insulating connecting portion 12d.

[0114] The present disclosure and embodiments can be summarized as follows.

[0115] The coaxial connector 10 according to one embodiment of the present disclosure comprises: an internal terminal 14 connected to the center conductor 41 of the coaxial cable 40; an external terminal 16 having a base portion 16a, the base portion 16a being formed with a rivet engaging portion 16c connected to the outer conductor 43 of the coaxial cable 40; and an insulating member 12 arranged between the internal terminal 14 and the external terminal 16 and accommodating the internal terminal 14.

The coaxial connector 10 is characterized in that the internal terminal 14 has a central conductor 41 connected to the coaxial cable 40; and an external terminal 16 having a central conductor 41 connected to the outer conductor 43 of the coaxial cable 40. 0, the connecting arm portion 14b has a first mounting portion 14f and a second mounting portion 14m on the coaxial cable 40 side, and a first slit 14g and a second slit 14n for receiving the center conductor 41 are formed on the first mounting portion 14f and the second mounting portion 14m, respectively.

[0129] Furthermore, in the coaxial connector 10 according to one embodiment, a misalignment angle a between the first direction A1 and the second direction A2 is greater than or equal to 1 degree and less than or equal to 15 degrees.

[0130] According to the above embodiment, the center conductor 41 of the coaxial cable 40 can be smoothly inserted into each of the first slit 14g and the second slit 14n, and the first mounting portion 14f and the second mounting portion 14m can clamp the center conductor 41 of the coaxial cable 40 at different positions.
