(Composition of coaxial connector Refer to Figure 1 to Figure 4)

Hereinafter, the coaxial connector 10 as an embodiment will be described with reference to the drawings. Further, the direction in which the casing 12, the bushing 14, and the socket 16 in the coaxial connector 10 are overlapped is set to the z-axis direction, and the positive direction thereof is from the casing 12 toward the socket 16. Further, the direction in which the coaxial cable 220 extends is referred to as the x-axis direction, and the direction orthogonal to the x-axis direction and the z-axis direction is referred to as the y-axis direction. The positive direction of the x-axis direction is from the direction of the coaxial cable 220 toward the socket 16. The x-axis direction is orthogonal to the z-axis direction.

As shown in FIGS. 1 and 2, the coaxial connector 10 includes a housing 12, a bushing 14, and a socket 16. Further, as shown in FIGS. 3 and 4, the coaxial connector 10 can be detachably attached to the socket 230 having the outer conductor 232 and the center conductor 234.

As shown in FIG. 2, the coaxial cable 220 is composed of an insulating film 221, an outer conductor 222, an insulator 223, and a center conductor 224. The insulator 223 is disposed around the center conductor 224 and has elasticity. The outer conductor 222 is disposed around the insulator 223. The insulating film 221 is provided around the outer conductor 222 and has elasticity. Further, the coaxial cable 220 is exposed in the order of the insulator 223 and the outer conductor 222 from the front end thereof.

The casing 12 is made of a single metal plate (for example, phosphor bronze for spring), and as shown in FIG. 2, the cylindrical portion 20, the lid portion 22, the holding portion 23, and the fixing portion 24 are included.

The cylindrical portion 20 has a cylindrical shape having a central axis extending in the z-axis direction. Therefore, the cylindrical portion 20 has an opening on the positive side and the negative side in the z-axis direction. However, a part of the cylindrical portion 20 (a portion on the negative side in the x-axis direction) is cut away. Thereby, when the cylindrical portion 20 is viewed from the z-axis direction, it is C-shaped. The central axis of the cylindrical portion 20 is orthogonal to the direction in which the coaxial cable 220 extends, and is preferably in the range of 90 ° ± 5 °.

The fixing portion 24 is for clamping and fixing a plate-like portion of the bushing 14 having a surface parallel to the x-axis and the z-axis from both sides in the y-axis direction. Further, the fixing portion 24 extends from the portion where the cylindrical portion 20 is cut toward the direction in which the coaxial cable 220 extends, that is, the negative direction side in the x-axis direction. Here, as described above, the cylindrical portion 20 is C-shaped by being cut. Therefore, the cylindrical portion 20 has two end portions. The fixing portion 24 extends from the respective end portions toward the negative side in the x-axis direction. Further, since the flat fixing portion 24 extends from each end portion of the C-shaped cylindrical portion 20, the connecting portion J is formed to be retracted.

Further, the fixing portion 24 is provided with a bent portion 33. The curved portion 33 is formed by bending one portion of the fixing portion 24 toward the positive side or the negative side in the y-axis direction.

The lid portion 22 is a plate-shaped member that covers the opening of the cylindrical portion 20 on the negative side in the z-axis direction. The following bushing 14 is placed on the lid portion 22. Further, since the lid portion 22 is formed by bending the same metal plate as the cylindrical portion 20, the portion of the cylindrical portion 20 on the positive side in the x-axis direction is connected by the bent portion Q. Further, both ends of the lid portion 22 in the y-axis direction are bent toward the positive side in the z-axis direction. Further, the bent portion can be divided into the diameter expansion suppressing portion 25 and the first pressing portion 26 depending on the position thereof.

The diameter expansion suppressing portion 25 is provided along the arc from the arc of the cylindrical portion 20 in the y-axis direction toward the negative side in the x-axis direction.

The first pressing portion 26 is a portion adjacent to the diameter expansion suppressing portion 25 on the negative side in the x-axis direction. In addition, the first crimping portion 26 largely extends toward the positive side in the z-axis direction from the diameter expansion suppressing portion 25 in a state before the assembly of the coaxial connector 10. Further, when the coaxial connector 10 is assembled, the first pressing portion 26 is folded toward the inner side of the casing 12, and the first pressing portion 26 is wound around the fixing portion 24 and the insulator 223 of the coaxial cable 220. around. Thereby, the first crimping portion 26 is pressed against the fixing portion 24 and the insulator 223. At this time, the fixing portion 24 and the insulator 223 are pressed against the first pressing portion 26 and are pressed against the bushing 14 . That is, the fixing portion 24 and the pressing portion 26 hold the bushing 14. Therefore, the first pressing portion 26 functions to fix the bushing 14, the socket 16, and the coaxial cable 220 to the casing 12.

As shown in FIG. 2, the holding portion 23 is a plate-like member that extends along the coaxial cable 220. Moreover, the holding portion 23 is connected to the end portion of the lid portion 22 on the negative side in the x-axis direction. Further, the holding portion 23 can be divided into the second pressing portion 27 and the third pressing portion 28. Further, the second pressing portion 27 and the third pressing portion 28 are sequentially arranged from the positive side in the x-axis direction toward the negative side.

The second crimping portion 27 and the third crimping portion 28 are U-shaped when viewed from the negative side in the x-axis direction in a state before assembly of the coaxial connector 10. Further, when the coaxial cable 220 is attached to the coaxial connector 10, the coaxial cable 220 is pressed into the bottom of the U-shape, and the second pressing portion 27 and the third pressing portion 28 are wound around the coaxial cable 220. The method is bent, whereby the coaxial cable 220 is fixed to the casing 12. At this time, the second crimping portion 27 is in contact with the outer conductor 222 of the coaxial cable 220, and the third crimping portion 28 is in contact with the insulating coating 221 . Further, a groove G orthogonal to the x-axis direction is formed on the inner circumferential surface of the second crimping portion 27 and the third crimping portion 28 that is in contact with the coaxial cable 220, The fall of the coaxial cable 220 is prevented.

The bushing 14 is composed of an insulator made of a resin (for example, a liquid crystal polymer), and functions to insulate the casing 12 from the socket 16. The bushing 14 is attached to the casing 12, and as shown in FIG. 2, is composed of a circular portion 36 and a holding portion 38.

The circular portion 36 functions to hold the socket 16, and is composed of a rear surface portion 39 and a cylindrical portion 41 as shown in Fig. 2 . The back surface portion 39 is a plate-like member that is circular when viewed in plan from the z-axis direction in the fitting direction. Further, the back surface portion 39 is a portion that is housed in the cylindrical portion 20 when the bushing 14 is attached to the casing 12.

As shown in FIG. 2, the cylindrical portion 41 is provided on the surface of the back surface portion 39 on the positive side in the z-axis direction, and has a central axis extending in the z-axis direction. Further, the central axis of the cylindrical portion 41 of the bushing 14 substantially coincides with the central axis of the cylindrical portion 20 of the housing 12.

The holding portion 38 functions to hold the socket 16 and is configured by the back surface portion 42 and the pressing portion 46. The back surface portion 42 is a plate-like member that extends from the back surface portion 39 of the circular portion 36 toward the negative side in the x-axis direction. Further, both ends of the back surface portion 42 in the y-axis direction are bent toward the positive side in the z-axis direction. Therefore, the cross section 42 has a U-shaped cross section. Here, in the portion of the back surface portion 42 which is bent toward the positive side in the z-axis direction, the side wall 38a which is a portion near the end portion on the negative side in the x-axis direction extends longer than the other portions in the z-axis direction. Further, a groove extending in the extending direction of the back surface portion 42 is formed substantially at the center of the side wall 38a in the z-axis direction. Further, when the first crimping portion 26 is bent to attach the coaxial cable 220 to the coaxial connector 10, the first crimping portion 26 is bent from the groove portion, and the side wall 38a is sandwiched between the insulator 223 and the first pressing portion 26. Thereby, the insulation of the coaxial connector 10 and the coaxial cable 220 can be improved.

The pressing portion 46 is a plate-shaped member perpendicular to the x-axis direction, and is to be coaxially When the cable 220 is assembled to the coaxial connector 10, the portion touched by the front end of the coaxial cable 220. Here, a gap Sp is provided between the end portion on the negative side in the z-axis direction of the pressing portion 46 and the surface on the positive side in the z-axis direction of the back surface portion 42. Similarly, a gap Sp is also provided between the cylindrical portion 41 and the surface of the back surface portion 42 on the positive side in the z-axis direction. Thereby, the space on the negative side in the x-axis direction of the pressing portion 46 communicates with the internal passage gap Sp of the cylindrical portion 41.

Further, the bushing 14 can be separated into two. Specifically, the bushing 14 is divided into one half of the positive side in the y-axis direction and one half of the negative side in the y-axis direction in a V shape. Thereby, the socket 16 described below can be attached to the bushing 14.

The socket 16 is made of a metal plate (for example, phosphor bronze for spring), as shown in FIG. 1, attached to the bushing 14, and insulated from the casing 12 by the bushing 14. Moreover, as shown in FIG. 2, the socket 16 is comprised by the cylindrical part 48, the back surface part 50, and the mounting part 52.

The cylindrical portion 48 is connected to the positive side in the x-axis direction of the back surface portion 50, and has a shape in which one of the annular portions is cut away when viewed in plan from the z-axis direction. The radius of the cylindrical portion 48 is smaller than the radius of the cylindrical portion 41 of the bushing 14. Further, when the coaxial connector 10 is assembled, as shown in FIG. 1, the cylindrical portion 48 is housed in the cylindrical portion 41. Further, the cylindrical portion 48 is located at the center of the cylindrical portion 20 when viewed from the direction in which the central axis of the cylindrical portion 20 extends (z-axis direction).

As shown in FIG. 3 and FIG. 4, the back surface portion 50 is a plate-like member that extends in the negative direction of the x-axis direction from the cylindrical portion 41 so as to pass through the gap Sp. The mounting portion 52 is provided at an end portion on the negative side in the x-axis direction of the back surface portion 50 by being bent perpendicularly to the positive side in the z-axis direction, and is connected to the center conductor 224 of the coaxial cable 220. Specifically, the attachment portion 52 is composed of two pieces of cutting sheets 52a and 52b that are arranged in a predetermined gap. Further, the crimping portion 26 is formed by sandwiching the center conductor 224 of the coaxial cable 220 between the cutting sheets 52a and 52b. The coaxial cable 220 is pressed against the cutting sheets 52a and 52b from the positive side in the z-axis direction to the negative side. Thereby, the cutting pieces 52a and 52b are crimped to the insulator 223 of the coaxial cable 220 by the force from the pressing portion 26. Then, the cutting pieces 52a and 52b cut (destroy) one of the insulators 223 of the coaxial cable 220 and connect them to the center conductor 224.

(assembly of coaxial connector)

The coaxial connector 10 constructed as above is assembled by the steps described below.

First, the socket 16 is attached to the bushing 14. Specifically, the socket portion 16 is sandwiched by the bushing 14 from both sides in the y-axis direction so that the cylindrical portion 48 is housed in the cylindrical portion 41 and the back surface portion 50 is accommodated in the gap Sp.

Next, the bushing 14 is attached to the housing 12. Specifically, the circular portion 36 is housed in the cylindrical portion 20, and the holding portion 38 is accommodated between the fixing portions 24, and the bushing 14 is press-fitted into the casing 12 from the positive side in the z-axis direction to be mounted. .

Next, the coaxial cable 220 in a state in which the outer conductor 222 and the insulator 223 are exposed is placed on the mounting portion 52. At this time, the center conductor 224 is not exposed. Then, the coaxial cable 220 is placed on the socket 16 such that the insulator 223 is placed on the mounting portion 52, the outer conductor 222 is positioned on the second pressing portion 27, and the insulating film 221 is positioned on the third pressing portion 28.

After the coaxial cable 220 is placed, the compacting of the coaxial cable 220 to the coaxial connector 10 is performed. First, the insulator 223 is pressed against the cutting sheets 52a and 52b by bending the first pressing portion 26. Thereby, one portion of the insulator 223 is cut by the cutting sheets 52a and 52b, and the cutting sheets 52a and 52b are connected to the center conductor 224.

Next, the second crimping portion 27 is bent so as to be wound around the outer conductor 222. Further, the third pressing portion 28 is bent so as to be wound around the insulating film 221. After the above steps, The coaxial connector 10 is in a state of being connected to the coaxial cable 220 as shown in FIG.

(Installation of coaxial connector to socket) Refer to Figure 3 and Figure 4)

Next, the attachment and detachment of the coaxial connector 10 to the socket 230 will be described. As shown in FIG. 3, the socket 230 is composed of an outer conductor 232 and a center conductor 234. The outer conductor 232 is a cylindrical electrode. The center conductor 234 is an electrode that protrudes toward the negative side in the z-axis direction from the center of the outer conductor 232.

When the coaxial connector 10 is fitted to the socket 230, as shown in FIG. 3, the outer conductor 232 is housed in the cylindrical portion 20. Thereby, the inner circumferential surface of the cylindrical portion 20 is in contact with the outer circumferential surface of the outer conductor 232, and the outer conductor 222 of the coaxial cable 220 and the outer conductor 232 of the socket 230 are electrically connected through the casing 12.

Further, while the outer conductor 232 is housed in the cylindrical portion 20, the center conductor 234 is inserted into the cylindrical portion 48 of the socket 16 as shown in FIG. Thereby, the outer peripheral surface of the center conductor 234 is in contact with the inner peripheral surface of the cylindrical portion 48, and the center conductor 224 of the coaxial cable 220 and the center conductor 234 of the socket 230 are electrically connected through the socket 16.

(effect)

According to the coaxial connector 10 configured as described above, the reduction in the fitting force with the socket 230 can be suppressed. Specifically, when the coaxial connector 10 is fitted to the socket 230, the cylindrical portion 20 of the coaxial connector 10 is enlarged by the outer conductor 232 of the socket 230. As a result, the shape of the cylindrical portion 20 collapses, and the fitting force with the socket 230 becomes weak. However, in the coaxial connector 10, as shown in FIG. 2, a diameter expansion suppressing portion 25 is provided around the cylindrical portion 20. Thereby, before the cylindrical portion 20 is expanded and plastically deformed, the cylindrical portion 20 is applied with a restoring force in the direction toward the center of the cylindrical portion 20 by the diameter expansion suppressing portion 25. Therefore, the coaxial connector 10 can suppress collapse due to the shape of the cylindrical portion 20. The resulting fitting force with the socket 230 is weakened.

Further, in the casing 12 of the coaxial connector 10, since the flat-shaped fixing portion 24 extends from each end portion of the C-shaped cylindrical portion 20, the connecting portion J thereof is retracted. The connecting portion J is disposed at a position intermediate the bent portion Q and the pressing portion 26. Further, since the end portions of the C-shaped cylindrical portion 20 are retracted in this manner, the connecting portion J is easily deformed when the coaxial connector 10 is fitted to the socket 230. Here, in the casing 12 of the coaxial connector 10, the diameter expansion suppressing portion 25 is provided along the arc from the arc of the cylindrical portion 20 in the y-axis direction toward the negative side in the x-axis direction. In other words, the diameter expansion suppressing portion 25 is also provided around the connecting portion J. Therefore, in the coaxial connector 10, the diameter expansion suppressing portion 25 is provided around the easily deformable portion of the casing 12, so that the collapse of the shape of the cylindrical portion 20 can be more effectively suppressed, thereby suppressing the socket 230. The chimerism is weakened. Further, the diameter expansion suppressing portion 25 may be provided in contact with the cylindrical portion 20 without being fitted into the socket 230. Alternatively, the diameter expansion suppressing portion 25 may be provided so as to be closest to the outer side of the cylindrical portion 20 with the connection portion J connected to the cylindrical portion 20 in a state where the socket 230 is not connected, or the diameter expansion suppressing portion 25 may be It is set only in the way of the connection portion J. It is preferable that two diameter expansion suppressing portions 25 are provided at a position symmetrical with respect to the line on the x-axis, and the pair of diameter expansion suppressing portions 25 arranged in line symmetry are provided. In the case where a pair of line-symmetric arrangement-inhibiting portions 25 are provided, the restoring force applied by the diameter-enlargement suppressing portion 25 acts symmetrically on the cylindrical portion 20 by being arranged in line symmetry with respect to the x-axis. Plastic deformation of the cylindrical portion 20 due to stress concentration can be suppressed.

(First Modification) Referring to FIG. 5)

The coaxial connector 10A according to the first modification is different from the coaxial connector 10 as an embodiment in the shape of the diameter expansion suppressing portion 25. In the coaxial connector 10A as the first modification In the middle, the diameter expansion suppressing portion 25 is provided only around the arc of the cylindrical portion 20 in the y-axis direction. Specifically, when the coaxial connector 10 is viewed from the z-axis direction, the diameter expansion suppressing portion 25 is provided so that the angle α formed by the line segment L1 and the line segment L2 is substantially 90°, and the line segment L1 connects the center of the cylindrical portion 20 and The center of the diameter expansion suppressing portion 25 in the x-axis direction, the line segment L2 is connected to the center of the cylindrical portion 20, and the extension line of the center conductor 224 of the coaxial cable 220 when the coaxial cable 10A is connected to the coaxial connector 10A is the center line. The intersection with the cylindrical portion 20. Even if the diameter expansion suppressing portion 25 has such a shape, the diameter expansion suppressing portion 25 is located around the cylindrical portion 20, so that the fitting force with the socket 230 due to the collapse of the shape of the cylindrical portion 20 can be suppressed.

(Second modification, see Fig. 6)

The coaxial connector 10B according to the second modification is different from the coaxial connector 10A as the first modification in that the angle α is approximately 100°. In the cylindrical portion 20, substantially from the bent portion Q on the positive side in the x-axis direction to the lid portion 22, the closer to the middle portion of the pressing portion 26 and the bent portion Q fixed to the lid portion 22 The easier it is to deform. Therefore, by setting the angle α to 100° greater than 90°, it is possible to suppress the deformation of the bent portion Q corresponding to the fixed end and the portion farther from the pressing portion 26 . In other words, the coaxial connector 10B according to the second modification can more effectively suppress the collapse of the shape of the cylindrical portion 20 than the coaxial connector 10A of the first modification, and can suppress the insertion with the socket 230. The joint force weakens.

(Third Modification) Referring to FIG. 7)

The coaxial connector 10C according to the third modification is different from the coaxial connector 10A as the first modification in that the angle α is approximately 120°. Thereby, the line segment of the diameter expansion suppressing portion 25 and the bent portion Q which are provided on both sides of the cylindrical portion 20 in the y-axis direction are respectively formed in an equilateral triangle. Further, the cylindrical portion 20 is well oriented from the three apexes thereof toward the center of the cylindrical portion 20. Balance the application of restoring force. Therefore, by setting the angle α to 120°, it is possible to satisfactorily suppress the collapse of the shape of the cylindrical portion 20, and it is possible to suppress the weakening of the fitting force with the socket 230.

(Fourth Modification) Referring to FIG. 8)

The coaxial connector 10D according to the fourth modification is different from the coaxial connector 10 as an embodiment in the shape of the diameter expansion suppressing portion 25. Specifically, the shape of the diameter expansion suppressing portion 25 of the coaxial connector 10D according to the fourth modification is a combination of the diameter expansion suppressing portion 25 of the coaxial connector 10A as the first modification and the coaxial connector as the third modified example. The diameter expansion suppressing portion 25 of 10C has a shape in which a plurality of diameter expansion suppressing portions 25 are provided on one side of the cylindrical portion 20 in the y-axis direction. As shown in FIG. 8, a plurality of pairs of line-symmetric arrangement of the diameter expansion suppressing portion 25 that is disposed in line symmetry with respect to the first pair of the connecting portions J and the diameter expanding suppressing portion 25 that is disposed in line symmetry with respect to the second pair are provided on the basis of the x-axis. The diameter expansion suppressing portion 25. Even if the diameter expansion suppressing portion 25 has such a shape, the diameter expansion suppressing portion 25 is located around the cylindrical portion 20, so that the fitting force with the socket 230 due to the collapse of the shape of the cylindrical portion 20 can be suppressed. By arranging the plurality of pairs of the line-diameter-disposed diameter expansion suppressing portions 25, the stress acting on the diameter-enlargement suppressing portion 25 can be reduced, and the deformation of the diameter-expanding suppressing portion 25 itself can be suppressed. It is preferable that the distance between the cylindrical portion 20 in the state in which the socket is not inserted and the diameter expansion suppressing portion 25 in which the first pair is line-symmetrically arranged is shorter than the distance between the cylindrical portion 20 and the diameter expansion suppressing portion 25 in which the second pair is diagonally arranged. .
