DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector having an outer conductor for coupling at one end and a coaxial cable fixing member at the other ten ends.

The object of the present invention is to provide a structure in which the coaxial cable can be extremely easily fastened to the above-mentioned fastening member, and furthermore, the structure is simple and the handling operation is as simple as possible. The aim is to provide a connector for

The drawings showing the embodiments of the present application will be described below.

Reference numeral 1 indicates a base body, which is usually made of an insulating material such as plastic.

Reference numeral 2 indicates an outer conductor made of a conductive material, the base of which is fitted into the base 1 as shown in FIG.

The center conductor 3 located at the center of this is made by protruding the core wire 8 of the coaxial cable,
In practice, the hollow conductor 3 may be made to protrude from the base 1 in advance, and the core wire 8 of the coaxial cable may be inserted and fitted into the hollow part of the base of the conductor 3. 4 is a hole through which the core wire 8 is inserted.

Reference numeral 5 indicates a cylindrical hole for fixing the outer conductor, and a portion of the deep part of the hole is penetrated and opened to the opposite side.

As shown in Figure T, a large number of conductive pieces 2b having elastic force extend from the base part 2a of the outer 90 conductor 2, and these conductive pieces penetrate the base body as shown in Figure 4 to the right side in the figure. It is designed to stand out. Next, the fastening member 9 has a large number of clamping pieces 6, a female threaded ring 10, and the above-mentioned conductive piece 2b. The clamping pieces 6 are each attached to the base body 1 with a base portion 6a having a thin wall, and a tip 6b having a thick wall. The number arrangement of these conductive pieces 2b is the same as that of the conductive pieces 2b, but the numbers do not necessarily have to be the same, and in the state shown in FIG. It is sufficient that the conductive pieces 2b match. The reference numeral 1b on the outer periphery of the base body 1 indicates a protruding part that can be easily placed with a finger, and 1a indicates a part that protrudes so that the end edge 11a of the waterproof cap 11 shown in FIG. shows the tapered part. Incidentally, the protrusion 1c formed on this slope is an engaging member that supports a position slightly closer to the base 11b than the tip of the waterproof cap, that is, a portion approximately indicated by the reference numeral 11c, to prevent it from abnormally deforming inward. It is. The outer conductor has slots 12 as shown in Figure 7.
The conductive piece 2b is made of a well-known conductive elastic material whose diameter can be varied to some extent, and which provides the elasticity of the conductive piece 2b. The base body 1 is also as shown in FIG. 7, and the clamping piece 6 is made of a material that can elastically contract toward the center and is integrally formed as a whole. Also, this base 1 has a seventh
The engaging piece 13 shown in the figure is provided protrudingly, and when the cap shown in FIG. 8 is mounted as shown in FIG. The engaging piece is inserted into the cap 11 to prevent the cap 11 from being accidentally removed. In addition, the inner diameter of the base portion 11b of the cap is made to correspond to the outer diameter of the cable 7 in order to obtain a watertight effect (
If the cable is large in diameter, cut the end appropriately to create a large diameter hole). Next, the dimensional relationship between the base body 1 and the fastening member 9 will become clear through the operating means described later, but it is also clear from the illustrated relationships in FIGS. 3, 5, and 6. The outer diameter at the B end face position is the smallest, and then the ring 10
The dimensional relationship is determined in order such that the inner diameter of the clamping piece 6 at the next C-C position is the largest, and the outer diameter of the clamping piece 6 at the C-σ position is the largest. When the clamping pieces 6 are elastically compressed toward the center, the inner diameter of the ring 10 is smaller than the inner diameter of the ring 10, and is approximately equal to the outer diameter of the B-B end face. Furthermore, the mutual relationship between the D and D positions in FIG. 3 is such that the ring will not come off in the right direction, and in this position, the clamping piece 6 can be compressed toward the center. The operating method for a certain device having the above configuration will be explained.

In manufacturing, the members shown in FIGS. 7 and 8 are first formed, and then the ring 10 is assembled in the state shown in FIG.
move to the left. In this case, if the clamping piece 6 is compressed to reduce the outer diameter of the C-C end face, the positional relationship as shown in FIG. 1 can be easily achieved. Prior to this work, the outer conductor 2 shown in FIG. 7 is installed in the ring-shaped hole 5 in the base, and the positional relationship between the two is configured as shown in FIG. 1. Next, move the coaxial cable 7 whose tip is stepped to the direction indicated by the arrow 1 in Fig. 1.
When it is moved in seven directions, it enters from the planned space 7a, resulting in the positional relationship shown in FIG. That is, the center conductor 8 of the coaxial cable is located at the center of the outer conductor 2 and serves as the center conductor 3 of the outer conductor, and the reticular outer conductor 7' of the coaxial cable is located inside the conductive piece 2b continuous with the outer conductor 2. Next, when the ring 10 is moved in the direction of arrow 18 to the state shown in FIG. will be blocked. In that case, the ring 10 is further advanced in the direction of the arrow 18 by rotating the ring 10, that is, by using the internal thread formed on the inner surface of the ring. This function is because the outer periphery of the clamping piece 6 is made of plastic, so the internal threads on the inner surface of the ring engage and force the ring to advance in the direction of arrow 18. In the state shown in FIG. 4, the conductive piece 2b is pressed in the direction of the strengthened outer conductor 7 and the insulating material 7 by the clamping piece 6, and electrical continuity becomes possible. Next, the cap 8 as shown in FIG. 8 is placed in the state shown in FIG. 3. In this case, when the groove 14 of the cap is aligned with the engaging piece 13 and the cap is pushed forward, the cap is then rotated, the engaging piece 13 engages with the engaging part 15 and the cap is fixed. This cap is made of a resilient material such as rubber or plastic, so that it can be resiliently attached to the base. As described above, in this invention, the free ends of the plurality of clamping pieces 6, 6...6 are given elasticity in the radial direction, so that the ring 10 can be clamped. When trying to attach it to the base side of the piece, use the free end 6b.
, 6b . . . 6b has the advantage that it can be made smaller than that shown in FIG. 5, making it easier to attach the ring 10. Furthermore, with the above configuration, the subsequent ring 10 will not have any problems. It has the advantage that the ring 10 can be fixed in a state that it will not come off as shown in Figure 1 without any special effort, and the ring 10 will not be lost during transportation.Furthermore, the free end of the clamping piece is normally in an expanded state. Because of this, when inserting the coaxial cable toward the center as shown in Fig. 2, the inner surface of the clamping piece acts as a funnel-shaped guide, and the insertion of the coaxial cable tips 8, 7' becomes easy. There are also features that make it easier.

Furthermore, according to the present invention, the inner surface of the ring 10 is provided with a female thread, while the outer periphery of the plurality of clamping pieces 6, 6...6 allows the female thread to be inserted, and the free end is Since it is expanded, it has the advantage of being able to change from the state shown in FIG. 2 to the state shown in FIG. 3 and fix the part 7' of the cable. This has the advantage that it can be used even if the outer diameter of the tip 7' of the coaxial cable to be inserted is thick or thin. There is also the effect of reducing man-hours as there is no need to form a thread groove corresponding to .
