1 is a bottom plan view showing the coaxial cable connector 1 of the present invention to which the coaxial cable 10 is wired, and FIG. 2 is an exploded perspective view showing the coaxial cable connector 1. The coaxial cable connector 1 has a bilaterally symmetrical shape sandwiching the HH center axis of FIG. 1 and mainly includes a conductive terminal 20, an insulating outer cover 40 integrally formed with the terminal 20, and at least a part of the cover outer cover 40. An outer conductor housing 70 of at least a portion of the coaxial cable 10. Further, since the terminal 20 and the outer cover 40 are integrally formed, they cannot be actually disassembled. However, in Fig. 2, for the sake of convenience, the state in which they are disassembled is illustrated. When the coaxial cable connector 1 is assembled, the terminal 20, the cover 40, or the coaxial cable 10 are pressed from the bottom side of the coaxial cable connector 1 to the upper side in the direction of the arrow "β" shown in the figure. The outer conductor casing 70 is disposed in this order and is fixed to the outer conductor casing 70.

The coaxial cable 10 has the same structure as the conventional coaxial cable, that is, from the outermost casing to the center, has an insulating coating 11, an outer conductor 12, an insulator 13, and a core wire 14. This structure is well known and therefore will not be described in detail.

The terminal 20 has a predetermined length along the axial direction α of the coaxial cable 10. A step portion 25 is provided in the vicinity of the middle of the main body portion 26. By the step portion 25, in the integrally formed outer cover 40, the rear end side (24) of the terminal 20 can be made closer to the coaxial side than the front end side (22). The cable 10, on the other hand, has a front end side (22) of the terminal 20 that is closer to the face 78 of the outer conductor housing 70 than the rear end side (24). At the rear end side (24) of the terminal 20, a connecting portion 24 is formed in contact with the core wire 14 of the coaxial cable 10, and at the connecting portion 24, when the coaxial cable connector 1 is assembled, a coaxial cable is disposed. The core 14 of the wire 10. Further, a contact portion 22 that is in contact with a center terminal (not shown) of the target connector is provided on the front end side (22) of the terminal 20. The contact portion 22 is provided in a state of standing toward the contact side with the target connector, and is a method in which the center terminal of the target connector is clamped to the elastic displacement portion 22' formed by the center. And was formed. Needless to say, it is not necessary to form the elastic contact portion 22', and for example, it may be formed by simply inserting a hole.

3 is a bottom side perspective view of the outer cover 40 integrally formed with the terminal 20, and FIG. 4 is a front side oblique view thereof. Fig. 4 is also a perspective view showing the bottom side of the outer conductor casing 70, which is changed to an angle different from that of Fig. 2. also, Figure 5 is a cross-sectional view taken along line A-A of Figure 1.

The outer cover 40 mainly includes a main body portion 46, a cylindrical portion 42 provided on the tip end side of the main body portion 46, and a cable fixing portion (41, 50, etc.) provided on the rear end side of the main body portion 46.

These parts are integrally formed with the terminal 20 by resin molding. However, a part of the terminal 20 remains exposed to the outside after the integral molding. The exposed portion of the terminal 20 of course includes the connecting portion 24, and further includes a portion of the elastic displacement portion 22' of the contact portion 22 of the bottom portion of the contact portion 22 and a peripheral portion thereof, or a portion of the upper surface side of the contact portion 22, that is, A portion of the opposite side (the upper surface side) of the contact portion 22 of the terminal 20 in the thickness direction of the terminal 20 and the opposite side of the outer conductor casing 70. Further, a part of the upper side of the contact portion 22 is also exposed, which is caused by a problem unique to the integral molding. That is, in order to suppress the sway of the terminal 20 against the flow of the resin at the time of integral molding, it is necessary to press a part of the terminal 20 by the mold, but at this time, the elastic displacement portion 22' of the bottom side which is originally required to be exposed is required. It is effective to press with the mold on the upper side of the elastic displacement portion 22'. However, the portion pressed by the mold will remain as the exposed portion 27 due to the through hole 48 of the resin. Therefore, the exposed portion 27 of the terminal 20 may include the contact with the terminal 20 in the thickness direction of the terminal. The person positioned on the opposite side of the portion 22.

The body portion 46 has a substantially cubic shape as a whole, but has a protruding portion 47 that protrudes toward the approaching side of the object connector. The protrusion 47 can serve as a slightly cylindrical portion 72 of the outer conductor housing 70. The discontinuous portion 73 is used to complement the portion.

The cylindrical portion 42 on the tip end side of the main body protrudes from the upper surface portion 45 toward the contact side with the target connector, and the contact portion 22 of the terminal 20 is disposed at the center thereof. When the target connector is fitted, the cylindrical portion 42 is inserted into the cylindrical casing of the target connector, and at the same time, the contact portion 22 disposed at the center of the cylindrical portion 42 is disposed in the circle. The center terminal (not shown) at the center of the cartridge case is inserted and brought into contact. The three projections 44 extending from the upper surface portion 45 of the cylindrical portion 42 toward the tip end side and the left and right sides are required to position the outer cover 40 to the outer conductor case 70.

A cable fixing portion (41, 50, etc.) on the rear end side of the main body portion is provided with an installation surface 41 for arranging the core wire 14 of the coaxial cable 10. After the terminal 20 and the outer cover 40 are integrally molded, the connection portion 24 of the terminal 20 is exposed from the installation surface 41. Further, the installation surface 41 is slightly flat, but may be designed in a state in which the connection portion 24 is protruded or recessed from the installation surface 41. Thereby, the contact between the terminal 20 and the core wire 14 becomes true. In the illustrated example, the recess 43 is designed.

In order to fix the core wire 14, a pair of crimping pieces 50A, 50B are provided in the cable fixing portions (41, 50, etc.). The pair of crimping pieces 50A and 50B are supported by only one side 53 on each side opposed to each other with the installation surface 41 interposed therebetween, and are supported toward the core wire 14 around the respective support portions 53A and 53B. Set the setting surface 41 and bend it.

The outer conductor case 70 is formed by punching and zigzag a piece of sheet metal. The outer conductor casing 70 mainly includes an arrangement surface 85 on which the outer cover 40 or the coaxial cable 10 is disposed, and is disposed in the outer conductor casing 70 The slightly cylindrical portion 72 on the tip end side of the surface 85 is provided with a plurality of caulking portions 80, 83, and 84. The slightly cylindrical portion 72 is a portion that is connected to a cylindrical casing (not shown) of the target connector when it is fitted to the target connector. The tip end side of the arranging surface 85 has a shovel shape as a whole, and the slightly cylindrical portion 72 is surrounded by the standing portion 74 constituting one of the spoon portions, and the strength of the slightly cylindrical portion 72 is strengthened.

As illustrated in detail in FIG. 4, the outer cover 40 is attached to the opposing surface 45 of the outer conductor housing 70 and has a raised portion 49 that bulges toward the outer conductor housing 70. The ridge portion 49 has, for example, a cross shape as a whole, and the through hole 48 in which the exposed portion 27 of one of the terminals 20 is exposed is an intersection point, and is formed by two straight portions having a predetermined width, in particular, on one straight line. The portion extends from the front end side of the terminal 20 to the length of the step portion 25 or more along the axial direction α of the coaxial cable 10. The raised portion 49 of the outer cover 40 is provided with a cross-shaped recessed surface on the surface 78 facing the surface 45 of the outer cover 40, which is recessed toward the opposite side to the one side of the outer cover 40. The recessed portion 79. The ridge portion 49 is provided with the ridge portion 49 and the recess portion 79 that can be accommodated in the recess portion 79, and when the outer cover 40 is disposed on the outer conductor casing 70, the terminal 20 and the outer cover 40 can be formed. The exposed portion 27 of the terminal 20 due to the generated through hole 48 is separated from the outer conductor case 70, and the insulation distance between the exposed portion 27 and the outer conductor case 70 can be increased. Therefore, the terminal 20 can be surely insulated from the outer conductor casing 70 with a simple structure, and the connector can be made short. Further, by providing the ridge portion 49 and the recess portion 79, when the outer cover 40 is disposed on the outer conductor casing 70, it is concave. The ridges 49 are embedded in the recesses 79, and the outer cover 40 can be easily positioned at a predetermined position on the outer conductor casing 70. Further, the shape of the ridge portion 49 or the recess portion 79 is not limited to a cross, and may be, for example, a triangular shape or a quadrangular shape. Moreover, the degree of the depression of the depressed portion 79 with respect to the raised portion 49 can also be large. In addition, the raised portion 49 does not necessarily have to be completely covered around the edge of the through hole 48, but the raised portion 49 may not be provided near the edge of the through hole 48, only in the embodiment shown in FIG. The ridge is provided away from the edge. It is important that the exposed portion 27 is separated from the outer conductor casing 70 by the ridge portion 49 and the recess portion 79. For example, the cross portion may be discontinuously formed. In particular, since the outer conductor casing 70 is formed of a plate-like metal, the recessed portion 79 can be easily formed by press working, and the manufacturing cost can be lowered. Further, the recessed portion 79 also has a role of reinforcing the strength of the outer conductor casing 70.

The slightly cylindrical portion 72 is coupled to the arrangement surface 85 in a state in which the bent portion 72' is bendable. When the outer cover 40 is placed at a predetermined position on the outer conductor casing 70, the substantially cylindrical portion 72 is bent toward the arrangement surface 85. 1 and 5 are all diagrams showing a state in which the slightly cylindrical portion 72 is bent. When the slightly cylindrical portion 72 is bent, the left and right protrusions extending from the front surface portion 45 of the cylindrical portion 42 between the notch 71 of the substantially cylindrical portion 72 and the surface 78 of the outer conductor casing 70 facing the outer cover 40 The 44 series are respectively sandwiched, whereby the outer cover 40 can be simply fixed to the outer conductor case 70. Similarly, the projection engaged with the front projection 44' is provided on the inner surface of the bent portion 72' of the outer conductor casing 70.

The caulking portion is a side opposite to each other with the arrangement surface 85 interposed therebetween The paired caulking portions are respectively configured to be formed. Here, a total of three sets are provided along the axial direction α of the coaxial cable 10, that is, the front side caulking portion 80, the intermediate caulking portion 83, and the rear side caulking portion 84. The front side caulking portions 80A and 80B are mainly required to caulk the pair of crimping pieces 50A and 50B from the outside, and the intermediate caulking portions 83A and B are mainly required to caulk the outer conductor 12, and the rear side caulking portion is required. The 84A and B series are mainly required for caulking the insulating coating 11.

The assembly work of the coaxial cable connector 1 will be described with reference to Figs. 6 to 9 . In addition, both FIG. 8 and FIG. 9 show the state after completion of assembly, but in FIG. 8, for convenience, one part of the front side crimping part 80 is removed, and the state of the crimping piece 50A, 50B is shown.

As shown in FIG. 6, after the outer cover 40 is attached to the outer conductor casing 70, as shown in FIG. 7, the coaxial cable 10 is positioned on the outer cover 40 or the outer conductor outer casing 70. At this time, the core wire 14 of the coaxial cable 10 is disposed on the installation surface 41 of the outer cover 40, and the outer conductor 12 of the coaxial cable 10 is disposed at a corresponding position of the intermediate caulking portion 83, and a coaxial cable The insulating coating 11 of 10 is disposed at a corresponding position of the rear side caulking portion 84.

Next, as shown in FIGS. 8 and 9, the front side caulking portions 80A and 80B, the intermediate caulking portion 83, and the rear side caulking portion 84 are respectively caulked to the outer cover 40 or the coaxial cable 10. At this time, the respective crimping pieces 50A and 50B are bent to the mounting surface 41 by the contact with the front side caulking portions 80A and 80B. As a result, the core wire 14 of the coaxial cable 10 is sandwiched between the crimping pieces 50A, Between 50B and the setting surface 41, it is fixed by it. If based With this configuration, the core wire 14 of the coaxial cable 10 can be held and fixed at the same time as the caulking operation of the front side caulking portions 80A and 80B, so that the work can be simplified. Further, the insulator 13 of the coaxial cable 10 is covered only by the extended portions 56, 57 of the pair of crimping pieces 50A, 50B when the pair of crimping pieces 50A, 50B are bent, so that the crimping portion It won't be special.

When the intermediate crimping portion 83 is caulked to the outer conductor 12, the outer conductor casing 70 is in contact with the outer conductor 12 through the intermediate caulking portion 83, and is electrically connected to the outer conductor 12. As a result, when the coaxial cable connector 1 is fitted to the target connector, the substantially cylindrical portion 72 of the outer conductor casing 70 is connected to the cylindrical casing of the target connector, and the outer conductor 12 and the object of the coaxial cable 10 are connected. The cylindrical housing of the connector is electrically connected. In the same manner, the rear side caulking portion 84 is caulked to the insulating coating 11, but of course, no qualitative connection occurs here. Further, as can be seen from FIG. 7 and the like, even after the assembly of the coaxial cable connector 1, the substantially cylindrical portion 72 is in the cylindrical direction of the substantially cylindrical portion 72 (the arrow "β" direction in FIG. 2), and Since the coaxial cable 10 does not overlap, the size of the outer conductor casing 70 and the outer cover 40 does not become large, so that the connector can be shortened.

Next, the configuration of the intermediate caulking portion 83 and the rear side caulking portion 84 will be described in more detail with reference to Figs. 10 and 13 . FIG. 10 is a cross-sectional view taken along line E-E of FIG. 1, FIG. 11 is a cross-sectional view taken along line E-E of FIG. 1, FIG. 12 is a cross-sectional view taken along line F-F of FIG. 1, and FIG. 13 is a cross-sectional view taken along line G-G of FIG. In addition, Figure 10 to Figure 13 are especially Although the cross section of the intermediate caulking portion 83 is shown, it can be seen from FIG. 1 to FIG. 9 or its description that the rear side caulking portion 84 can also be considered to be the same.

As described above, the intermediate caulking portion 83 is formed by caulking the coaxial cable 10, in particular, the outer conductor 12 and the rear side caulking portion 84, respectively, by insulating the insulating sheath 11. . In the present configuration, in order to increase the crimping strength of the intermediate crimping portion 83 or the rear side crimping portion 84 with respect to the coaxial cable 10, the caulking portions 83 and 84 are provided with convex portions and concave portions formed by pressing. . In the direction of α in Fig. 10, the convex portion 83a and the concave portion 83b are provided with the arrangement surface 85 interposed therebetween. Further, in Figs. 11 to 13, the intermediate caulking portion 83 is provided with at least one convex portion extending in the plane in contact with the coaxial cable 10 in a plane slightly orthogonal to the coaxial cable 10. Similarly to at least one recess 83b extending in the same direction, the rear caulking portion 84 is provided with the same at least the contact surface with the coaxial cable 10 in a plane slightly orthogonal to the coaxial cable 10. One convex portion 84a and at least one concave portion 84b. For example, regarding the intermediate caulking portion 83, a contact portion with the coaxial cable 10 in the cross section of Fig. 11 is provided with a convex portion 83a at which the arrangement surface 85 of the outer conductor casing 70 is positioned, and a bilaterally symmetric position thereof. The two concave portions 83b are provided with a concave portion 83b positioned at the arrangement surface 85 of the outer conductor casing 70 and two convex portions located at the left and right symmetrical positions in the contact surface with the coaxial cable 10 in the cross section of Fig. 12 . The portion 83a in contact with the coaxial cable 10 in the cross section of Fig. 13 is provided with a convex portion 83a positioned at the arrangement surface 85 of the outer conductor casing 70, and located therein, in the same manner as in the cross section of Fig. 11 Two concave portions 83b at the left and right symmetrical positions. The convex portion 83a at the arrangement surface 85 The side of the concave portion 83b is formed to be approximately equal in length, and the portion other than the arrangement surface of the respective caulking portions is such that the length of the convex portion 83a and the concave portion 83b is such that the concave portion 83b is formed relatively long. Further, the recess 83a' which appears on the opposite side of the convex portion 83a in the thickness direction is an indentation due to the formation of the convex portion 83a. By providing these convex portions and concave portions, when the intermediate caulking portion 83 or the rear side caulking portion 84 is caulked to the coaxial cable 10, the convex portions and the concave portions that are in contact with the coaxial cable 10 can be used. The coaxial cable 10 obtains the difference in bending height, and as a result, the crimp strength of the coaxial cable 10, particularly the crimp strength in the axial direction α of the coaxial cable 10, can be improved.

The convex portion and the concave portion have an excellent effect of improving the pressure-bonding strength to the coaxial cable 10, but on the other hand, due to the degree of bending of the coaxial cable 10, the impedance is disturbed. The impedance disorder generally occurs in a plane slightly orthogonal to the coaxial cable 10 as the distance between the outer conductor 12 and the core wire 14 in the radial direction changes, but in the present invention, the coaxial cable In the slightly orthogonal plane of 10, the concave portion and the convex portion are arranged in groups, whereby the change can be cancelled.

For example, as shown in Figs. 11 and 13, by providing the convex portion 83a on the arrangement surface 85, the outer conductor 12 of the coaxial cable 10 is pressed in the radial direction toward the center side, and the distance between the outer conductor 12 and the core wire 14 becomes In the case of a small case, the impedance tends to be low. However, in the present configuration, the convex portions 83a corresponding to the arrangement surface 85 are symmetrically arranged in a bilateral direction by the respective sides facing each other across the arrangement surface 85. The recessed portion 83b diffuses the outer conductor 12 of the coaxial cable 10 in the radial direction from the center side to the outside, and increases the distance between the outer conductor 12 and the core wire 14 in these portions. On, the impedance will become higher. As described above, the convex portion 83a and the concave portion 83b are provided in a plane slightly orthogonal to the coaxial cable 10, whereby the impedance of the "low" tendency and the impedance of the "high" tend to cancel each other. Maintaining the crimp strength while reducing the degradation of impedance.

As shown in FIG. 10, the concave portion and the convex portion may be alternately arranged along the axial direction α of the coaxial cable 10 to form the above-described cancellation relationship. For example, in the intermediate caulking portion 83, three sets of concave portions and convex portions are provided along the axial direction α, and two sets of concave portions and convex portions are provided in the rear side caulking portion 84. By alternately arranging the plurality of pairs in the axial direction α, the crimp strength of the coaxial cable can be further improved, and the impedance can be adjusted more easily.

Further, the impedance is affected by the strength of the caulking caused by the caulking portion. However, in the present configuration, the outer conductor casing 70 has the opposing faces disposed on the disposition surface 85 on which the coaxial cable 10 is placed. The pair of caulking portions 83A, B, 84A, and B are disposed on the side. Therefore, by caulking the pair of caulking portions, the force on the left and right sides can be easily adjusted, and the impedance can be easily performed. Adjustment.

Of course, the present invention is not limited to the above-described embodiments, and various modifications can of course be made. Therefore, the scope of the claims of the present invention includes various modifications that are commonly performed by the practitioner. For example, the number of recesses and projections in the plane slightly orthogonal to the coaxial cable 10 or the number of pairs in the axial direction α is not limited. Further, the terminal 20 and the outer cover 40 are not necessarily integrally formed, and the terminal 20 may be provided in the outer cover 40.

[Possibility of industrial use]

Since it has a general effect of improving the crimp strength and performing impedance adjustment, it can be widely used in a coaxial cable connector.
