In the L-type coaxial connector of patent document 1, when the insulating member is attached to the external terminal, the circular rear surface portion of the insulating member passes through the opening of the cylindrical portion of the external terminal. Therefore, the back surface portion is configured to have an outer diameter smaller than an inner diameter of the cylindrical portion.

Patent document 1: japanese patent application laid-open No. 2010-80262
In the L-type coaxial connector of patent document 1, since the outer diameter of the back surface portion is smaller than the inner diameter of the cylindrical portion, there are gaps in the X-axis direction and the Y-axis direction between the outer surface portion of the back surface portion and the inner surface portion of the cylindrical portion. Therefore, the outer surface portion of the back surface portion does not contact the inner surface portion of the cylindrical portion. Further, the L-type coaxial connector of patent document 1 does not disclose how to position the rear surface portion of the insulating member with respect to the cylindrical portion of the external terminal in the X-axis direction and the Y-axis direction.

[ coaxial connector component ]
Fig. 4 is a plan view of the coaxial connector assembly 30 after the L-shaped coaxial connector 10 is fitted to the mating connector 20. Fig. 5 is a sectional view taken along line V-V of fig. 4.
As shown in fig. 4 and 5, the coaxial connector assembly 30 includes an L-shaped coaxial connector 10 and an opposite connector 20 that is fitted to the L-shaped coaxial connector 10 so as to be insertable and removable in an insertion/removal direction (Z-axis direction). The coaxial connector assembly 30 of fig. 5 is shown in a state in which the L-type coaxial connector 10 and the mating connector 20 are fitted to each other by moving the mating connector 20 in the insertion and extraction direction (Z-axis direction) toward the L-type coaxial connector 10 in a state in which the mating connector 20 is opposed to the L-type coaxial connector 10. The L-shaped coaxial connector 10 is connected to the coaxial cable 40, and the mating connector 20 is mounted on a circuit board not shown.
[ L-shaped coaxial connector ]
Fig. 1 is a plan view of an L-shaped coaxial connector 10 constituting the coaxial connector assembly 30 shown in fig. 4 and 5. Fig. 2 is a perspective view of the L-shaped coaxial connector 10 shown in fig. 1. Fig. 3 is a sectional view taken along the line III-III of fig. 1.
As shown in fig. 1 to 3, the L-type coaxial connector 10 includes an insulating member (bushing) 12, an inner terminal (center socket) 14, and an outer terminal (housing) 16. As for the electrical connection components, the L-shaped coaxial connector 10 is configured such that: the center conductor connecting portion 14b and the inner contact portion 14a have substantial symmetry with respect to a virtual center line O connecting the center conductor connecting portion 14b and the inner contact portion 14a, which will be described later, when viewed in the axial direction (Z-axis direction).
The inner terminal 14 is a terminal connected to the center conductor 42 of the coaxial cable 40. The inner terminal 14 is electrically insulated from the outer terminal 16 by the insulating member 12.
The internal terminal 14 is made of a conductive member. The internal terminal 14 is made of, for example, one metal plate such as a copper alloy material, and its surface is plated with nickel and gold. The inner terminal 14 is integrated with the insulating member 12 by insert molding. With this configuration, the insulating member 12 and the inner terminal 14 can be accurately positioned.
The inner terminal 14 includes an inner contact portion 14a and a center conductor connecting portion 14 b. As shown in fig. 3, the inner terminal 14 is bent in an L shape in a cross-sectional view.
The inner contact portion 14a extends in the insertion/removal direction (Z-axis direction) which is an axial direction orthogonal to the extending direction of the coaxial cable 40. The inner contact portion 14a is formed in a substantially cylindrical shape partially notched in the circumferential direction.
The internal contact portion 14a is in electrical contact with the counterpart internal contact portion 24a of the counterpart internal terminal 24 of the counterpart connector 20. The inner contact portion 14a shown in fig. 2 and 3 is configured as a female type (socket type) having a contact surface on an inner peripheral portion. On the other hand, the mating inner contact portion 24a of the mating connector 20 is configured as a male type (pin type) having a contact surface on the outer peripheral portion.
The center conductor connecting portion 14b extends in a transverse direction (X-axis direction) perpendicular to the extending direction of the coaxial cable 40, i.e., the inserting and extracting direction. The center conductor connecting portion 14b is a plate-like terminal portion extending in the lateral direction from the inner contact portion 14 a. The center conductor connecting portion 14b is electrically connected to the center conductor 42 of the coaxial cable 40 in the assembled state shown in fig. 1 to 3. A bifurcated portion 14s is formed at the end of the center conductor connecting portion 14b on the coaxial cable 40 side. The branch portion 14s and the center conductor 42 are fixed and electrically connected by soldering.
The external terminal 16 is a terminal connected to the external conductor 41 of the coaxial cable 40. The external terminal 16 is made of a conductive material. The external terminal 16 is made of, for example, a single metal plate such as a copper alloy material, and the surface thereof is plated with nickel and gold.
The external terminal 16 includes an external conductor connecting portion 16a, an external contact portion 16b, a caulking engagement portion 16c, a rotation restricting portion 16d, and a stopper portion 16 e.
The outer conductor connecting portion 16a extends in a transverse direction (X-axis direction) from the outer contact portion 16b and has a plate shape. The outer conductor connecting portion 16a is provided along the insulating member 12 and the coaxial cable 40 in the assembled state shown in fig. 1 to 3, and holds the insulating member 12 and the coaxial cable 40. The outer conductor connecting portion 16a is formed with an outer contact portion 16b, a caulking engagement portion 16c, a rotation restricting portion 16d, and a stopper portion 16 e.
The external contact portion 16b is cylindrical and is fitted to the counterpart external terminal 26 of the counterpart connector 20. The external contact portion 16b extends in the axial direction, i.e., the plug-and-play direction (Z-axis direction). The external contact portion 16b has an opening on one side of the coaxial cable 40 as viewed in the axial direction, i.e., the insertion/removal direction (Z-axis direction). The internal holding portion 12a of the insulating member 12 is inserted into the external contact portion 16b through the opening of the external contact portion 16b and attached thereto. According to this configuration, compared to the case where the plurality of spring pieces are formed in the cylindrical portion of the external terminal by the plurality of slits extending in the axial direction, the external contact portion 16b is less likely to be deformed, and therefore stable fitting can be achieved. In the assembled state shown in fig. 1 to 3, the inner contact portion 14a of the inner terminal 14 is located inside the outer contact portion 16 b. At this time, the outer contact portion 16b is positioned coaxially with the inner contact portion 14 a.
The external contact portion 16b is substantially cylindrical and has a cut-out portion formed by cutting one side of the coaxial cable 40 in the circumferential direction into an arc shape. The central conductor holding portion 12b of the insulating member 12 is inserted and attached through the notch portion.
The caulking engaging portion 16c extends from the outer conductor connecting portion 16a in the axial direction, i.e., the insertion and extraction direction (Z-axis direction). The caulking engagement portion 16c is formed of a pair of plate-like members formed to face each other in the width direction (Y-axis direction). The caulking engaging portion 16c is bent toward the imaginary center line O and caulked to contact the outer conductor 41 of the coaxial cable 40. Thereby, the external terminal 16 is electrically connected to the external conductor 41, and the coaxial cable 40 is held and fixed to the external terminal 16.
The retaining portion 16e is provided in a side extension portion 16g extending from the external contact portion 16b to one side of the coaxial cable 40. The retaining portion 16e extends from the side extension portion 16g in the axial direction, i.e., the insertion/removal direction (Z-axis direction). The retaining portion 16e is formed of a pair of plate-like members formed to face each other in the width direction (Y-axis direction). The distal end of the retaining portion 16e is engaged with the retaining recess 12e of the center conductor holding portion 12b by bending and caulking the retaining portion 16e toward the imaginary center line O. According to this configuration, the central conductor holding portion 12b of the insulating member 12 is prevented from coming off in the axial direction, i.e., the plug-in direction (Z-axis direction) by the coming-off prevention portion 16e, and the insulating member 12 is held and fixed to the external terminal 16.
The rotation restricting portion 16d is provided on a side extending portion 16g of the external terminal 16 on the opposite side of the external contact portion 16b, and is configured to abut against a side portion of the center conductor holding portion 12 b. The rotation restricting portion 16d is located on the side of the coaxial cable 40 with respect to the stopper portion 16 e. The stopper portion 16e is located between the external contact portion 16b and the rotation restricting portion 16 d. With this configuration, the rotation restricting portion 16d can restrict the rotation of the center conductor holding portion 12b about the inner contact portion 14 a. The rotation restricting portion 16d is preferably located on the side of the coaxial cable 40 as far as possible, and is located farther from the inner contact portion 14 a.
The end of the side extending portion 16g extends to extend outward in the width direction (Y-axis direction), and abuts against the inner surface of the caulking engaging portion 16 c. That is, when viewed from the axial direction, i.e., the insertion and extraction direction (Z-axis direction), the end of the side extension portion 16g extends so as to extend outward in the width direction (Y-axis direction) along the branch portion 14s of the center conductor connection portion 14 b. With this configuration, the distance between the branch portion 14s in the width direction (Y-axis direction) and the end of the side extension portion 16g can be kept substantially equal, and the electric field and the capacitive coupling therebetween can be prevented from becoming non-uniform, so that unnecessary reflection in a high frequency band (for example, a megahertz band or a gigahertz band) can be reduced.
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 (e.g., liquid crystal polymer) and electrically insulates the internal terminal 14 and the external terminal 16 from each other.
The insulating member 12 includes an inner holding portion 12a and a central conductor holding portion 12 b.
The internal holding portion 12a is substantially circular when viewed from the axial direction, i.e., the insertion and extraction direction (Z-axis direction). The internal holding portion 12a is configured to have a dimension that can be attached to the inside of the external contact portion 16b in the axial direction, i.e., the plug-and-play direction (Z-axis direction), through the opening of the external contact portion 16 b. In the internal holding portion 12a, the internal contact portion 14a of the internal terminal 14 bulges in the axial direction, i.e., the plug-in direction (Z-axis direction). The inner contact portion 14a is integrated with the inner holding portion 12a so as to be coaxial with the inner holding portion 12 a. For example, the inner contact portion 14a is integrated with the inner holding portion 12a, and a part of the center conductor connecting portion 14b is integrated with the inner holding portion 12a by insert molding. With this configuration, the insulating member 12 and the inner terminal 14 can be accurately positioned.
The center conductor holding portion 12b extends from the inner holding portion 12a toward the coaxial cable 40. The center conductor holding portion 12b is substantially rectangular when viewed from the axial direction, i.e., the insertion/removal direction (Z-axis direction). The remaining portion of the central conductor connecting portion 14b is embedded in the central conductor holding portion 12b and exposed from the central conductor holding portion 12 b. The exposed end of the center conductor connection portion 14b is electrically connected to the center conductor 42 as the branch portion 14 s. A pair of retaining recesses 12e are formed in the upper surface portion of the center conductor holding portion 12b in the width direction (Y-axis direction).

The target internal terminal 24 is a terminal connected to a signal pad portion of a circuit board, not shown. The target internal terminal 24 is electrically insulated from the target external terminal 26 by the target insulating member 22.
The target internal terminal 24 is made of a conductive material. The counterpart internal terminal 24 is made of a single metal plate such as a copper alloy material, for example, and the surface thereof is plated with nickel or gold. The target inner terminal 24 is integrated with the target insulating member 22 by insert molding. With this configuration, the target insulating member 22 and the target internal terminal 24 can be accurately positioned.
The target internal terminal 24 includes a target internal contact portion 24a and a target internal mounting portion 24 b. As shown in fig. 5, the counterpart internal terminal 24 is bent in an L-shape in a cross-sectional view.
The object side inner contact portion 24a extends in the axial direction, i.e., the plug-in direction (Z-axis direction). The target-side inner contact portion 24a has a substantially cylindrical shape. The counterpart inner contact portion 24a is in contact with and electrically connected to the inner contact portion 14a of the inner terminal 14 of the L-type coaxial connector 10. The target internal contact portion 24a shown in fig. 4 and 5 is configured as a male type (pin type) having a contact surface on the outer peripheral portion. The target internal mounting portion 24b is electrically connected to a signal pad portion of a circuit board, not shown, via a conductive member such as solder.
The target external terminal 26 is a terminal connected to a ground pad portion of a circuit board, not shown. The target external terminal 26 is made of a conductive material. The target external terminal 26 is made of, for example, a single metal plate such as a copper alloy material, and the surface thereof is plated with nickel and gold. The target external terminal 26 is integrated with the target insulating member 22 by insert molding. With this configuration, the target insulating member 22 and the target external terminal 26 can be accurately positioned.
The target external terminal 26 includes a target external mounting portion 26a and a target external contact portion 26 b. The target 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.
The counterpart external contact portion 26b extends in the axial direction, i.e., the insertion and extraction direction (Z-axis direction). The target external contact portion 26b has a substantially cylindrical shape. The target outer contact portion 26b is arranged coaxially with the target inner contact portion 24 a. The counterpart external contact portion 26b is in contact with and electrically connected to the external contact portion 16b of the external terminal 16 of the L-type coaxial connector 10. A fitting recess 26h is formed in the outer peripheral surface of the target external contact portion 26 b. When the L-shaped coaxial connector 10 is fitted to the mating connector 20, the fitting concave portion 26h of the mating external contact portion 26b is fitted to the fitting convex portion 16h of the external contact portion 16 b.
[ positioning of insulating Member ]
As shown in fig. 1 to 3, 5, and 7, the positioning portion 17 is disposed on the inner surface portion 16j of the external contact portion 16b of the external terminal 16. The positioning portion 17 is a convex portion (e.g., a hemispherical shape) that protrudes radially inward from the inner surface portion 16j toward the outer surface portion 12j of the internal holding portion 12 a. The positioning portion 17 protrudes radially inward from the inner edge of the outer contact portion 16b toward the outer surface portion 12 j. The positioning portion 17 is located between the fitting convex portion 16h and the bottom portion of the external conductor connecting portion 16a in the axial direction, i.e., the plug-and-play direction (Z-axis direction). The positioning portion 17 is configured to abut against the outer surface portion 12j of the internal holding portion 12 a. According to this structure, the convex positioning portion 17 functions as a reinforcement, and therefore the external contact portion 16b of the external terminal 16 is not easily deformed.
As shown in fig. 1, the four positioning portions 17 are arranged substantially line-symmetrically with respect to a virtual center line O connecting the center conductor connection portion 14b and the inner contact portion 14a when viewed from the axial direction, that is, the insertion and extraction direction (Z-axis direction). The four positioning portions 17 may be arranged equally in the circumferential direction. According to this configuration, since the positioning portion 17 can prevent the electric field and the capacitive coupling from becoming uneven, unnecessary reflection in a high frequency band (for example, a megahertz band or a gigahertz band) can be reduced.
The positioning portion 17 may be formed of three pieces, and may be arranged substantially line-symmetrically with respect to the virtual center line O as viewed in the axial direction, i.e., the insertion/removal direction (Z-axis direction). In this case, one positioning portion 17 is located on the imaginary center line O and on the opposite side of the center conductor connecting portion 14b, and the other two positioning portions 17 are arranged substantially line-symmetrically with respect to the imaginary center line O as viewed from the axial direction, that is, the inserting and extracting direction (Z-axis direction). One positioning portion 17 of the three positioning portions 17 may be located on the imaginary center line O and on the opposite side of the center conductor connecting portion 14b, and the three positioning portions 17 may be arranged in a regular triangle and uniformly in the circumferential direction when viewed from the insertion and extraction direction (Z-axis direction), which is the axial direction. According to this configuration, since the positioning portion 17 can prevent the electric field and the capacitive coupling from becoming uneven, unnecessary reflection in a high frequency band (for example, a megahertz band or a gigahertz band) can be reduced.
The positioning portion 17 may be formed in such a manner that one circular arc-shaped convex portion is positioned on the opposite side of the center conductor connecting portion 14b and extends in a length capable of positioning in the X-axis direction and the Y-axis direction. The positioning portion 17 may extend in an arc shape at an angle of about 45 degrees to about 300 degrees, for example. As described above, the positioning portion 17 may be in a form capable of positioning in two orthogonal directions (X-axis direction and Y-axis direction) orthogonal to the axial direction (Z-axis direction) of the inner contact portion 14 a.
The positioning portion 17 disposed in the external contact portion 16b can position the internal holding portion 12a in two orthogonal directions (X-axis direction and Y-axis direction) orthogonal to the axial direction (Z-axis direction) of the internal contact portion 14 a.
As described above, the rotation restricting portion 16d is provided on the side of the coaxial cable 40 of the center conductor holding portion 12b (on the opposite side of the internal holding portion 12 a). The rotation restricting portion 16d restricts the rotation of the center conductor holding portion 12b about the inner contact portion 14a by abutting against the side portion of the center conductor holding portion 12 b. That is, the rotation restricting portion 16d can restrict the rotation of the internal holding portion 12a in the θ direction around the internal contact portion 14 a.
According to the above configuration, the positioning portion 17 performs positioning of the internal holding portion 12a in two orthogonal directions (X-axis direction and Y-axis direction) orthogonal to the axial direction (Z-axis direction) of the internal contact portion 14a, and the rotation restricting portion 16d restricts rotation of the center conductor holding portion 12b about the internal contact portion 14 a. Therefore, the insulating member 12 can be accurately positioned with respect to the external terminal 16. That is, the internal holding portion 12a of the insulating member 12 (the internal contact portion 14a of the internal terminal 14) and the external contact portion 16b of the external terminal 16 can be arranged coaxially.
[ modified example ]
A modified example of the positioning structure of the insulating member 12 in the L-type coaxial connector 10 will be described with reference to fig. 8 to 10. Fig. 8 is a plan view of the L-shaped coaxial connector 10 according to the modification. Fig. 9 is a bottom view of the coaxial connector assembly 30 after the mating connector 20 is fitted to the L-shaped coaxial connector 10 of fig. 8. Fig. 10 is a sectional view taken along line X-X of fig. 9.
As shown in fig. 10, the L-type coaxial connector 10 includes a positioning portion 17 on one side of an internal holding portion 12a of an insulating member 12. A positioning portion 17 is disposed on the outer surface portion 12j of the internal holding portion 12 a. The positioning portion 17 is a convex portion (e.g., a hemispherical shape) that protrudes from the outer surface portion 12j toward the inner surface portion 16j of the outer contact portion 16b, i.e., outward in the radial direction. The positioning portion 17 protrudes further toward the inner surface portion 16j, i.e., radially outward than the inner edge of the outer contact portion 16 b. The positioning portion 17 is located between the upper and lower portions of the internal holding portion 12a in the axial direction, i.e., the plug-in direction (Z-axis direction). The positioning portion 17 is configured to abut against the inner surface portion 16j of the external contact portion 16 b.
As shown in fig. 8, the four positioning portions 17 are arranged substantially line-symmetrically with respect to a virtual center line O connecting the center conductor connection portion 14b and the inner contact portion 14a, as viewed in the axial direction, i.e., the insertion and extraction direction (Z-axis direction). The four positioning portions 17 may be arranged equally in the circumferential direction. According to this configuration, since the positioning portion 17 can prevent the electric field and the capacitive coupling from becoming uneven, unnecessary reflection in a high frequency band (for example, a megahertz band or a gigahertz band) can be reduced.
The positioning portion 17 may be formed of three parts, and arranged substantially line-symmetrically with respect to the virtual center line O when viewed from the axial direction, i.e., the insertion/removal direction (Z-axis direction). In this case, one positioning portion 17 is located on the imaginary center line O and on the opposite side of the center conductor connecting portion 14b, and the two positioning portions 17 are arranged substantially line-symmetrically with respect to the imaginary center line O when viewed from the axial direction, that is, the inserting and extracting direction (Z-axis direction). One positioning portion 17 of the three positioning portions 17 may be located on the imaginary center line O and on the opposite side of the center conductor connecting portion 14b, and the three positioning portions 17 may be provided so as to form an equilateral triangle when viewed from the axial direction, that is, the insertion and extraction direction (Z-axis direction). According to this configuration, since the positioning portion 17 can prevent the electric field and the capacitive coupling from becoming uneven, unnecessary reflection in a high frequency band (for example, a megahertz band or a gigahertz band) can be reduced.
The positioning portion 17 may be formed in such a manner that one circular arc-shaped convex portion is positioned on the opposite side of the center conductor connecting portion 14b and extends in a length capable of positioning in the X-axis direction and the Y-axis direction. The positioning portion 17 may extend in an arc shape at an angle of about 45 degrees to about 300 degrees, for example. As described above, the positioning portion 17 may be in a form capable of positioning in two orthogonal directions (X-axis direction and Y-axis direction) orthogonal to the axial direction (Z-axis direction) of the inner contact portion 14 a.
The positioning portion 17 disposed in the internal holding portion 12a can position the internal holding portion 12a in two orthogonal directions (X-axis direction and Y-axis direction) orthogonal to the axial direction (Z-axis direction) of the internal contact portion 14 a.
As shown in fig. 8 and 10, the insulating member 12 is configured to be dividable into two parts in the Y-axis direction along a dividing line 19. The dividing line 19 extends on the imaginary center line O. The insulating member 12 is provided with an internal terminal installation space in which the internal terminal 14 is installed. The insulating member 12 is composed of two substantially equally divided insulating portions, i.e., one insulating portion 12s and the other insulating portion 12 t. The one insulating portion 12s and the other insulating portion 12t have fitting structures (convex portions and concave portions) for mechanical fitting, respectively.
