And the fixing seat W 2:!% is shaped and pressed against the fixing ring wall of the ring base 511, and the coupling ring wall (2) on the concave section 323 of the ring soil is tightly fitted by the fixing seat 200812163 52 Combined with the concave ring segment 323 of the base 3, the electric clamp ring 51 can be mounted on the base 3. After the cable clamp ring 51 is mounted and adjacent to the insertion portion 3 11 of the assembly lane 31. See Figures 5 and 6. When the joint of the embodiment is assembled, the metal jacket 42 is loaded into the center socket 4U of the center guide W, and the center guide 41 and the insulating seats 43 and 44 are mounted together on the assembly lane 31 by the joint 45. The cable clamp ring 5 is mounted on the bottom edge of the base 3 by the fixing base 52. After the mounting, the jaw 512 of the cable clamp ring 51 protrudes toward the radially inner end and is adjacent to the insertion portion 311. When the connector of the embodiment is in use, the wire end 2 of the cable 2 is inserted by the insertion portion 311 of the base 3. When inserted, the center wire 21 of the cable 2 passes through the insertion channel of the insertion tube 34. 341, the insulating pair hole 441 of the lower insulating seat 44 is finally inserted into the center insertion hole 411 of the center guide 41, because the metal is disposed in the center insertion hole 411 The sleeve 42 and the metal jacket 42 are surrounded by a plurality of clips 421, so that the center wire 21 of the cable 2 can be placed at the radially outer end of the cable 2 during assembly so as to be centered by the metal jacket 42 The guide member 41 is correctly abutted against the center wire 21. At the same time, the inner sleeve 22 of the cable 2 also extends into the insertion projection 34 of the base 3, and the insertion projection 34 is used to surround the inner sleeve. The surrounding wire 23 of the 22 is externally supported, that is, the aforementioned peripheral wire 23 is thus abutted against the outer surface of the insertion tube 34, since the mounting ring 33 and the pedestal ring 33 of the base 3 and the surrounding wall 32 are both The metal material is manufactured, and therefore, the aforementioned insertion operation can ensure that the surrounding wire 23 and the metal base 3 abut against each other for grounding purposes. At the same time, when the plug is inserted, the sleeve 24 also passes through the inner diameter due to the cable 2 10 200812163 The pawl 512 is smaller than the outer diameter of the outer sleeve 24, so that during the insertion process, the outer sleeve 24 pushes the rearward inner end of the claw 512 into the assembly ball and internally. The state of the card is stable, and the electricity is embedded in the electricity. 2. That is, the connector of the present invention is used as long as it is used. The wire end of the second end is inserted into the insertion portion 311 of the assembly path 31, so that the work of the group skirt can be easily performed, and the assembly is not only simple, but also the product is not known, and the solder is not required at all. And complying with the requirements of environmental protection. Referring to Figure 7, the second preferred embodiment of the connector of the present invention also includes a base 3, a central guiding unit U, and a μ unit 5, wherein the base 3 and the fixed base 5 The configuration is substantially the same as that of the first embodiment, and will not be described again, and the center guiding unit 4 also includes a center guide 41. An insulating seat not shown in the drawing, and a member for mounting the aforementioned components on the base 3. The joint 45 is different from the first embodiment in that the center guide 41 is a solid = rod-shaped body, and the joint 45 is rotatably mounted on the base 3; The change in the form of the order % 4 allows the connector to be used with a variety of different types of sockets. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made in accordance with the scope of the invention and the description of the invention. All remain within the scope of the invention patent.
