Although 22 is made up of a better solution to the electrical properties of the early layer of elastic material, the invention is not limited to 20 200903931 with any suitable layer structure. In the embodiment of the present invention, the two-layer processing method of the U-stress control layer in the adapter 2 of the prior art is solved by using the above-mentioned single-layer elastic material layer with stress control. Accordingly, the 5 adapter 1 2 of the present invention is simple in manufacturing and significantly reduces the manufacturing cost of the adapter 2. In this embodiment, the adapter 2 is injection molded or compression molded. Since the above-mentioned injection molding or compression molding step is used privately, the adapter 2 is molded one by one in the production process, so that the yield is greatly increased. The present invention is not limited thereto, and the adapter 2 can be formed by other suitable manufacturing methods. Figure 3 is an illustration of the adapter 2 of the present invention placed after the support core 3〇2. The towel is an open adapter, 3G2 is a support rope, 3〇3. The cable is inserted into the cavity, and 304 is the core rope withdrawal end. As shown in FIG. 3, the support core rope 3〇2 is a hollow structure, the soybean meal has a predetermined rigidity of 15 and its length is longer than the expanded adapter 3〇1 to form an electric slow insertion space in the core cord 302. The cavity 3〇3 is pinched to be larger than the electric (4) 11 1 material diameter, so that the electric environment is inserted into the electric cable insertion cavity 303 when the adapter is in the open state. Referring to Figure 3, the length of the core cord withdrawal end 3〇4 is sufficient for the operator to pull the cord take-up end 3〇4 after the cable is installed in the adapter after being opened.

C 15 20 An injection or molded adapter 2〇1 is expanded over the support core 3〇2; then the cable is inserted into the adapter in the expanded state and inserted into the cavity 303; Then, the adapter 2〇1 in the open state is mounted into the electric iron connection cavity 107 of the τ-shaped connector rail sleeve, thereby mounting the adapter 201 to the 连接 connector rail sleeve Finally, by pulling the core rope withdrawal end 3〇4' to pull the support core rope from the state of engagement with the adapter, pull down f. Since the adapter is composed of a layer of elastic material, it automatically shrinks by its own elastic function and is attached to the cable with a maintained radial pressing force, so that the type of adapter can cover several cables. section. 4 is a schematic diagram of the structure of the τ-shaped connector and the electro-optical connection of the present invention. In the figure, the terminal is connected to the terminal, and the operation is an electric thin conductor, which is completely screwed into a cold-shrinked adapter, and 405 is an adapter. Electrical I insulator, 406 vertical 'outer shield, 4G7 is the grounding wire, the gamma is the electric shield copper shield, and the electric galvanized. ...

Electrical and Cable Insulators 12 200903931 • The electron mirror conductor 402 is shorter than the length of the inner semiconductive shield 1 () 5 . Cable The -end of the body 402 (the upper end in Figure 4) is connected to the wishing terminal. The inside of the dust terminal 40 is a deep hole. The outer diameter of the electric material tearing is better than that of the sub-401. The aperture is small. From the cymbal, during the installation process, the electric magic conductor 402 is easily inserted into the crimp terminal 4Qi. The length of the cable conductor is longer than the hole depth of the waste terminal 401, so that the electrical conductor can be exposed therefrom after being mounted in the crimp terminal 401. The reference numeral 4〇4 in 10 15^4 indicates the cold-retracted adapter. As before, the adapter 2 has a hollow structure including a battery and an adapter connecting the cavity tearing and core, and sealing the cavity 203. As shown in FIG. 4, after the adapter 2 is connected to the τ-shaped connecting wire sleeve 1 to form a Τ-shaped connector, the money-filled adapter 4〇4 is electrically rotated to form a position where the cavity 2〇3 is located. (4) The end. See the end of the 0 4 adapter exposed from the vertical cavity portion of the τ-shaped main insulating sleeve 1〇2. In the embodiment shown in FIG. 4, the cable seal cavity 203 in the installed adapter 4〇4 corresponds to the position of the metal shield layer 408, such as the copper shield layer 4〇8. At this time, a sealant is applied to the space between the cable sealing cavity 203 of the adapter and the metal shield layer 4〇8, thereby achieving sealing of the τ-shaped connector. The outer diameter of the electrical insulator 405 is larger than the inner diameter 2 of the unopened adapter 201 so that it can form a tight fit with the adapter after the cable is installed in the adapter. In the cold-shrinkable integrated T-shaped cable connector shown in US Pat. No. 2,050,022, 722 (A1), since the adapter is not provided, the thickness of the crimping terminal matched thereto becomes larger as the cable cross section increases. ° When the cable cross section exceeds a certain range, due to the increase of the thickness of the crimping terminal 13 200903931, the τ-shaped connector of the invention is electrically connected to the electron mirror insulator 405 which is unable to disk the inner cavity (for example, the voltage level is 8.7/1) The dielectric mirror has an insulation thickness of 4.5 mm) and is in contact with the outer shield 4〇6, which does not provide sufficient insulation strength for the cable. In the present invention, however, since the adapter is provided, 5 the adapter is composed of a layer of elastic material and has a predetermined thickness, for example, 9 mm, which can be adapted to fit a cable having a wider cross-section. After the adapter 4〇4 is connected to the cable 409 by the above-mentioned “cold shrinkage” method, the boundary between the cable outer shield 406 and the cable insulator 4〇5 should be located in the middle of the cold-shrinkable adapter 404, so that It is more effective to realize the lateral insulation of the cable from the outside. Then, the assembled combination of the adapter 4〇4, the cable 409 and the crimp terminal 401 is inserted into the cable connection cavity 107 in the τ connector shoe cover i to form the butt connection in the present invention. The unit is connected to the cable and the component 4 is connected. In addition, referring to Fig. 4, a grounding hole 1?6 is further provided on the outside of the T-shaped connector shoe.

The T-shaped main body, the sleeve S 1 is formed by the electrical device connecting member 506 and the insulating plug 504 5 to form a threaded connection cavity 5〇2. The connection screw 5〇1 and the coupling nut thin 503 are located in the bolt connection cavity 5()2. The connector terminal of the connector and the cable connecting assembly of the item 4 is fixed to the electrical device connecting member 506 through the screwing member. In an embodiment, the threaded connection element comprises: a connection screw 5 连接 a connection bolt passing through the other 10 end of the crimp terminal 4 ' 'the end is screwed with the external electrical equipment connection part; and the connection nut 503 A coupling nut is used to fasten the crimp terminal 4〇1 to the external electrical device connecting member 506. The insulating plug 504 has an insert 5041 and an insert 5 〇 42 inside. The insert 5〇42 is embedded in the first end of the insulating plug (the left end in Fig. 5), has a 15 threaded hole in the inside, and is threadedly engaged with the other end of the connecting bolt 501, thereby inserting the insulating plug through the insert 5042 504 is connected to the connecting bolt 5〇1. The insert C; 5041 is embedded in the second end of the insulating plug 504 opposite the first end (right end in Fig. 5). When the insulating plug 504 is installed, the insert 5041 functions as an operating member. The operator mounts the insulating plug 504 into the insulating plug cavity 103 of the τ-shaped main flange 1 by twisting the insert 5041. The semiconductive shield tail plug 505 is mounted on the insert 5〇41 of the insulating plug 5〇4 and the insert 5041 of the insulating plug 504 is connected to the outer semiconductive shield 101 of the stirrup connector rail 1.
