Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for coaxial cables.

In conventional connectors, when connecting a coaxial cable to the connector body, the shield wire of the coaxial cable is connected to the ring K.
The structure is such that the ring is soldered and fixed to the connector body by screwing a tightening ring through a rubber washer. This soldering process is complicated and difficult, as it involves carefully unraveling the net-like shield wire and attaching it uniformly to the outside of the ring.Moreover, the tensile force exerted by the coaxial cable acts on the entire coaxial cable. The purpose of this structure is to improve mechanical strength and reduce electrical troubles such as poor contact.

The coaxial cable connector of the present invention includes a connector main body, a split ring made up of a plurality of rig pieces disposed around a seam and a dower that are folded back to the outside of an external insulating material at the end of the coaxial cable; A tightening ring is screwed into the connector body to press the split ring to the coaxial cable, and the outer peripheral surface of the split ring is formed with a tapered surface that becomes thinner on the opposite side from the end of the coaxial cable. %1 that the ring has a pressure contact surface that presses against the tapered surface of the ring.

1:J＼μ Below, to explain the embodiment of the present invention in detail, in the first and second figures, 1 is a connector, 2 is the same
fIk-pull, and this coaxial cable 2 is
= The connector 1 is composed of a core wire 21 of the river center, an internal insulating material 22 arranged concentrically around it, a mesh shield wire 23, and an external insulating material 24; A split ring 4 consisting of a plurality of ring pieces 41 arranged around the shield wire 23 folded back to the outside of the external insulating material 24 at the end of the coaxial cable 2; 4 to the coaxial cable 2. The split ring 4 has a coaxial cable 2 on its outer peripheral surface.
The tapered surface C is tapered on the side opposite to the end of the coaxial cable 2, and a thread groove-like uneven surface 43 is formed on the inner circumferential surface to press the end of the coaxial cable 2, and the tightening 95 is The inner peripheral surface of the tip has a pressure contact surface 51 that presses against the Qi Ji 42 of the split ring 4, and the outer peripheral surface has a screw 52 that is screwed into the screw hole 31 of the connector Fp, hs.

'i Connector with the configuration of coaxial cable 2-;
When connecting to a cable, first, as shown in FIGS. 3 to 5, the outer insulating material 2 at the end of the coaxial cable 2 is
4 to match the length of the split ring 4, expose the shield wire 23, fold it back to the outside of the external insulating material 24, and then peel off the internal insulating material 22 to match the connector body 3. Solder the pin 6 to the core wire 21 (Fig. 3). After performing the above processing, as shown in the figure, after passing the tightening ring 5 through the coaxial cable 2, the coaxial cable 2 is wrapped around the shield wire 23 with the ring pieces 41, 41 of the split ring 4. 5, and while pressing it lightly with your fingertips, pull the tightening ring 5 toward the outside of the split ring 4, as shown in FIG.

Insert the split ring 4 and the tip into the screw hole 31 of the connector body 3 and screw in the tightening ring 5.
By forming a pannier on the connector body 3 and the tightening ring and tightening the pannier hooks 32 and 53, the wedge 4 is pushed in the axial direction by a wedge effect, and the coaxial The cable 2 and the shield wire 23 are tightly tightened.

In the connector 1 attached to the coaxial cable 2 in this way, the tapered surface 42 of the split ring 4 is connected to the pressure contact surface 5 of the tightening ring 5.
1 and as the tightening ring 5 is screwed into the connector body 3, the split ring 4 is pushed in the axial direction, so the coaxial cable 2 is firmly tightened, and the coaxial cable 2 once fixed is tightened. At the same time, the force acts strongly,
Even if a large tensile force is applied to the coaxial cable 2, the radial component of the force acts in a direction that increases the tightening force.
Able to withstand large amounts of tension.

As described above, according to the present invention, the first complement I-
The cable can be simply and easily connected to the connector body, and after connection, the coaxial cable has a multi-pulsing force that acts on the entire coaxial cable, which improves mechanical strength. It is possible to reduce the occurrence of electric horse mackerel failure.
