In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figure 1As shown, an embodiment of the present invention provides a cable system including a cold-shrink cable terminal and a cable 10, one end of which is inserted into the cold-shrink cable terminal. The cable 10 can operate at 66kV, and correspondingly, the cold-shrink cable terminal is suitable for a 66kV voltage environment. Of course, the cold-shrink cable terminal can also be used in operating environments of the cable 10 such as 48kV, 35kV, and 27.5kV.

[0039] like Figure 1 As shown, the cold-shrink cable terminal includes a first terminal body 100 and a second terminal body 200. Specifically, the first terminal body 100 and the second terminal body 200 are manufactured separately, and the cold-shrink cable terminal is assembled from at least the first terminal body 100 and the second terminal body 200. It can be understood that manufacturing the first terminal body 100 and the second terminal body 200 separately is less difficult than molding the entire cable terminal as a single piece.

[0040] Furthermore, the first terminal body 100 is provided with a first cable channel 101, and the second terminal body 200 is provided with a second cable channel 201. The first terminal body 100 is connected to the second terminal body 200 and the first cable channel 101 is connected to the second cable channel 201.

[0041] Specifically, the first cable channel 101 passes through both ends of the first terminal body 100 along the axial direction, and the second cable channel 201 passes through both ends of the second terminal body 200 along the axial direction. The first terminal body 100 and the second terminal body 200 are connected axially so that the first cable channel 101 and the second cable channel 201 are connected, and the cable 10 can be inserted into the first cable channel 101 and the second cable channel 201.

[0042] It should be noted that, for the cold shrink cable terminal, before it is installed on the cable 10, the first cable channel 101 and the second cable channel 201 are filled with a support core strip. When the cold shrink cable terminal needs to be installed on the cable 10, the support core strip can be pulled out, and then the cable 10 can be inserted into the first cable channel 101 and the second cable channel 201. The first terminal body 100 and the second terminal body 200 can be shrunk and fitted onto the cable 10.

[0043] It is understood that the first terminal body 100 is longer than the second terminal body 200. The first terminal body 100 includes a first insulating portion 110 with a first cable channel 101 and a first umbrella skirt 120 disposed outside the first insulating portion 110. The first insulating portion 110 and the first umbrella skirt 120 are integrally molded from insulating rubber, which is elastic. Furthermore, the first terminal body 100 also includes a stress cone 130 disposed inside the first insulating portion 110. During the manufacturing of the first terminal body 100, the stress cone 130 can be molded first, and then the stress cone 130 can be placed into a mold to inject insulating rubber to form the first insulating portion 110 and the first umbrella skirt 120. The second terminal body 200 includes a second insulating portion 210 with a second cable channel 201 and a second umbrella skirt 220 disposed outside the second insulating portion 210. The second insulating portion 210 and the second umbrella skirt 220 are integrally molded from insulating rubber, and the second terminal body 200 is elastic. After the support core strip is inserted into the first cable channel 101 and the second cable channel 201, the diameter of the first cable channel 101 and the second cable channel 201 is enlarged. After the support core strip is removed, the diameter of the first cable channel 101 and the second cable channel 201 is reduced by the elasticity of the first terminal body 100 and the second terminal body 200, respectively.

[0044] Combination Figure 1 and Figure 2 Furthermore, the first terminal body 100 has a first connection end 102; the second terminal body 200 has a second connection end 202, the second connection end 202 is connected to the first connection end 102 and the second cable channel 201 is connected to the first cable channel 101.

[0045] It is understood that the first connecting end 102 is one end of the first terminal body 100 along the axial direction of the first terminal body 100, and the second connecting end 202 is one end of the second terminal body 200 along the axial direction of the second terminal body 200. The first connecting end 102 and the second connecting end 202 are connected together, so that the first terminal body 100 and the second terminal body 200 are axially connected, and the first cable channel 101 and the second cable channel 201 are connected.

[0046] Furthermore, the first connecting end 102 and the second connecting end 202 are connected by interlocking. In other words, the first connecting end 102 is sleeved on the outside of the second connecting end 202, or the second connecting end 202 is sleeved on the outside of the first connecting end 102.

[0047] Along the radial direction of the cold-shrink cable terminal, the first connecting end 102 is provided with a first sealing part 103 on the side near the second connecting end 202, and the second connecting end 202 is provided with a second sealing part 203 that seals and cooperates with the first sealing part 103 on the side near the first connecting end 102.

[0048] like Figure 2 As shown, in some embodiments, the second connecting end 202 is sleeved outside the first connecting end 102. The outer sidewall of the first connecting end 102 is provided with a first sealing portion 103, and the inner sidewall of the second connecting end 202 is provided with a second sealing portion 203. The second sealing portion 203 and the first sealing portion 103 are in a sealing fit, thereby improving the sealing performance of the connection position between the first terminal body 100 and the second terminal body 200. Further, the first sealing portion 103 is a first sealing protrusion ring disposed on the outer sidewall of the first connecting end 102. The first sealing protrusion ring extends circumferentially along the cold-shrink cable terminal; in other words, the first sealing protrusion ring extends circumferentially along the first connecting end 102, and the first sealing protrusion ring is coaxially disposed with the first cable channel 101. The second sealing portion 203 is a first annular groove disposed on the inner sidewall of the second connecting end 202. The first annular groove extends circumferentially along the cold-shrink cable terminal; in other words, the first annular groove extends circumferentially along the second connecting end 202. Furthermore, the first annular groove is coaxially arranged with the second cable channel 201; after the second connecting end 202 is sleeved onto the first connecting end 102, the first sealing protrusion is embedded in the first annular groove. This improves the sealing performance of the connection between the first terminal body 100 and the second terminal body 200. Additionally, the embedding of the first sealing protrusion in the first annular groove reduces the risk of axial separation between the first terminal body 100 and the second terminal body 200, thus improving the reliability of the connection between them. Of course, in other embodiments, the first sealing part 103 can be a first annular groove located on the outer sidewall of the first connecting end 102, and the second sealing part 203 can be a first sealing protrusion located on the inner sidewall of the second connecting end 202.

[0049] You can refer to Figure 2In other embodiments, the first connecting end 102 is sleeved outside the second connecting end 202. The inner wall of the first connecting end 102 is provided with a first sealing portion 103, and the outer wall of the second connecting end 202 is provided with a second sealing portion 203. Further, the first sealing portion 103 is a first sealing protrusion ring disposed on the inner wall of the first connecting end 102, extending circumferentially along the end of the cold-shrink cable. In other words, the first sealing protrusion ring extends circumferentially along the first connecting end 102, and is coaxially disposed with the first cable channel 101. The second sealing portion 203 is a first annular groove disposed on the outer wall of the second connecting end 202, extending circumferentially along the end of the cold-shrink cable. In other words, the first annular groove extends circumferentially along the second connecting end 202. Furthermore, the first annular groove is coaxially arranged with the second cable channel 201; after the first connecting end 102 is sleeved onto the second connecting end 202, the first sealing protrusion is embedded in the first annular groove. This improves the sealing performance of the connection between the first terminal body 100 and the second terminal body 200. Additionally, the embedding of the first sealing protrusion in the first annular groove reduces the risk of axial separation between the first terminal body 100 and the second terminal body 200, thus improving the reliability of the connection. Of course, in other embodiments, the first sealing part 103 can be a first annular groove located on the inner wall of the first connecting end 102, and the second sealing part 203 can be a first sealing protrusion located on the outer wall of the second connecting end 202.

[0050] like Figure 2 As shown, in some embodiments, there are multiple first sealing portions 103, which are spaced apart axially along the first connecting end 102; there are also multiple second sealing portions 203, which are spaced apart axially along the second connecting end 202; the multiple first sealing portions 103 and the multiple second sealing portions 203 are sealed and fitted in a one-to-one correspondence. This further improves the sealing performance of the connection between the first terminal body 100 and the second terminal body 200, and further reduces the risk of axial separation between the first terminal body 100 and the second terminal body 200.

[0051] Combination Figure 3 and Figure 4 The second terminal body 200 has a third connection end 204 disposed opposite to the second connection end 202; in other words, the end of the second terminal body 200 closer to the first terminal body 100 is the second connection end 202, and the end farther away from the first terminal body 100 is the third connection end 204.

[0052] The cold shrink cable terminal also includes a sealing cap 300, a sealing sleeve 400, and a terminal block 500. One end of the sealing cap 300 is sleeved on the outside of the third connection end 204, and the other end of the sealing cap 300 extends to the side of the second terminal body 200 away from the first terminal body 100. One end of the sealing sleeve 400 is sleeved on the other end of the sealing cap 300, and the other end of the sealing sleeve 400 extends away from the sealing cap 300. The terminal block 500 passes through the sealing sleeve 400.

[0053] It is understandable that the connection between the terminal 500 and the second terminal body 200 can be achieved by means of the sealing cap 300 and the sealing sleeve 400, and the sealing of the connection position between the terminal 500 and the second terminal body 200 is guaranteed by the sealing cap 300 and the sealing sleeve 400.

[0054] Specifically, the sealing cap 300 and the sealing sleeve 400 can also be made of insulating rubber and have elasticity. One end of the sealing cap 300 can be tightly fitted onto the third connecting end 204, and the other end of the sealing cap 300 can be tightly fitted onto one end of the sealing sleeve 400.

[0055] Furthermore, the end of the cable 10 has an exposed core 11. The cable 10 passes through the first cable channel 101 and the second cable channel 201, and the core 11 passes through and is connected to the terminal 500. The terminal 500 can be a bolt-type terminal, and the terminal 500 uses a breakable screw structure with constant torque to fix the terminal 500 to the core 11 of the cable 10.

[0056] Furthermore, the outer wall of the third connecting end 204 is provided with a third sealing part 205, and the inner wall of one end of the sealing cap 300 is provided with a fourth sealing part 301. The third sealing part 205 and the fourth sealing part 301 are sealed together. In this way, the sealing performance of the connection between the sealing cap 300 and the second terminal body 200 can be improved.

[0057] The third sealing part 205 is a second sealing protrusion ring disposed on the outer side wall of the third connecting end 204. The second sealing protrusion ring extends circumferentially along the end of the cold-shrink cable. In other words, the second sealing protrusion ring extends circumferentially along the end of the third connecting end 204, and the second sealing protrusion ring is coaxially disposed with the second cable channel 201. The fourth sealing part 301 is a second annular groove disposed on the inner side wall of one end of the sealing cap 300. The second annular groove extends circumferentially along the end of the cold-shrink cable. In other words, the second annular groove extends circumferentially along the sealing cap 300, and the second annular groove is coaxially disposed with the sealing cap 300. After one end of the sealing cap 300 is sleeved on the third connecting end 204, the second sealing protrusion ring is embedded in the second annular groove. In this way, the sealing performance of the connection position between the sealing cap 300 and the second terminal body 200 can be improved. In addition, the second sealing protrusion ring being embedded in the second annular groove can also reduce the risk of axial separation between the sealing cap 300 and the second terminal body 200, and improve the reliability of the connection between the sealing cap 300 and the second terminal body 200. Of course, in other embodiments, the third sealing part 205 may be a second annular groove provided on the outer side wall of the third connecting end 204, and the fourth sealing part may be a second sealing protrusion provided on the inner side wall of one end of the sealing cap 300.

[0058] Furthermore, there are multiple third sealing portions 205, which are spaced apart axially along the third connecting end 204. Similarly, there are multiple fourth sealing portions, which are spaced apart axially along the sealing cap 300. The multiple third sealing portions 205 and the multiple fourth sealing portions are fitted together in a one-to-one sealing manner. This further improves the sealing performance of the connection between the sealing cap 300 and the second terminal body 200, and further reduces the risk of axial separation between the sealing cap 300 and the second terminal body 200.

[0059] Furthermore, a third sealing protrusion 302 is provided on the outer wall of the other end of the sealing cap 300. The third sealing protrusion 302 extends circumferentially along the sealing cap 300, and one end of the sealing sleeve 400 is press-fitted with the third sealing protrusion 302. In this way, the sealing performance at the connection between the sealing cap 300 and the sealing sleeve 400 can be improved, and the risk of axial separation between the sealing cap 300 and the sealing sleeve 400 can be reduced.

[0060] Furthermore, there are multiple third sealing protrusions 302, which are spaced apart along the axial direction of the sealing cap 300.

[0061] In the cable system of this utility model, after the second connecting end 202 of the second terminal body 200 is sleeved with the first connecting end 102 of the first terminal body 100, the first sealing protrusion is embedded in the first annular groove. In this way, the sealing performance of the connection position between the first terminal body 100 and the second terminal body 200 can be improved. In addition, the first sealing protrusion embedded in the first annular groove can also reduce the risk of axial separation between the first terminal body 100 and the second terminal body 200, and improve the reliability of the connection between the first terminal body 100 and the second terminal body 200.
