Technical Field

[0001] The utility model relates to the field of high-voltage cable installation, and in particular to a T-shaped cable terminal installation device. Background Art

[0002] In the railway manufacturing industry, control lines and 110V / 400V busbars are laid in cable ducts and connected to various devices along the cable ducts. In the laying of cables, terminals or connectors are usually used to disconnect and connect the lines for convenient maintenance and functional control. However, for high-voltage cables connected to the high-voltage power grid, they pass through the end wall to reach the roof of the vehicle, and a breakpoint is added at the end wall. At the same time, the insulation of the high-voltage cable must be ensured at the end of the high-voltage cable to prevent discharge and ensure personal safety and equipment safety. However, commonly used connectors cannot meet this requirement. In order to prevent discharge at the end of the high-voltage cable, a T-type cable terminal is used to connect and transmit the cable. For this purpose, a T-type cable terminal installation device is proposed to achieve reliable and stable installation of the T-type cable terminal on the end wall. Summary of the invention

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0036] The frame 4 fixes the T-type cable terminal 2;

[0037] The protective cover 5 covers the locked T-type cable terminal 2.

[0038] Combination Figure 1As can be seen, after the frame 4, the protective cover 5 and the high-voltage cable 1 are assembled on the end wall 3, the T-type cable terminal 2 is firmly fixed on the end wall 3 by the frame 4, so that it is firmly installed on the end wall 3; the position where the high-voltage cable 1 is connected to the T-type cable terminal 2 is exposed through the semicircular through hole 512 set on the protective cover 5, and the rest of the T-type cable terminal 2 is completely covered by the protective cover 5, which can completely prevent maintenance personnel from stepping on the T-type cable terminal 2, thereby ensuring the safety and reliability of the T-type cable terminal 2.

[0039] Reference Figure 3 and Figure 4 In order to achieve a stable installation of the T-type cable terminal 2 on the end wall 3, the frame 4 in this embodiment includes: a bracket 41 fixed on the end wall 3 and a fixed pipe clamp 42 installed on the bracket 41;

[0040] The T-shaped cable terminal 2 is fixed on the fixed pipe clamp 42.

[0041] The fixed pipe clamp 42 can be set to multiple according to the needs. Figure 3 and Figure 4 From the perspective of the embodiment, there are three fixed pipe clamps 42, two of which are installed at the ends of the bracket 41, and one is installed in the middle of the bracket 41; wherein, flanges 4121 extend from the two side ends of the bracket 41, and a support plate 44 is fixed to the middle of the bracket 41 by welding, and arc grooves matching the outer shape design of the fixed pipe clamp 42 are formed on the top of the flange 4121 and the support plate 44, and then, the fixed pipe clamp 42 is connected to the flange 4121 and the support plate 44 by welding.

[0042] In addition, the width of each fixed pipe clamp 42 can be designed differently according to the needs. Figure 5 From the perspective of the embodiment, the width of the fixed pipe clamp 42 located in the middle is set to be wider, and its contact area in the middle position of the T-type cable terminal 2 is larger, thereby enhancing the installation stability of the T-type cable terminal 2.

[0043] In order to fix the T-type cable terminal 2 on the frame 4, as shown in FIG. Figure 5 and Figure 6 In this embodiment, each fixed pipe clamp 42 includes: a first arc-shaped pipe clamp 421 and a second arc-shaped pipe clamp 422 which are arranged opposite to each other. The T-shaped cable terminal 2 extends into the installation groove formed between the first arc-shaped pipe clamp 421 and the second arc-shaped pipe clamp 422. The first arc-shaped pipe clamp 421 and the second arc-shaped pipe clamp 422 are locked together by the first fastener 423 to fix the T-shaped cable terminal 2.

[0044] The first fastener 423 is a bolt or a T-bolt, and a welding nut 4211 connected to the first fastener 423 is pre-installed on the first arc-shaped pipe clamp 421. When installing the T-shaped cable terminal 2, the T-shaped cable terminal 2 is first placed on each first arc-shaped pipe clamp 421, and after being placed in place, each second arc-shaped pipe clamp 422 is sequentially installed on the corresponding first arc-shaped pipe clamp 421 through the first fastener 423.

[0045] In order to achieve a stable fixation of the bracket 41 on the end wall 3, refer to Figure 3 The bracket 41 in this embodiment includes: a fixing plate 411 attached to and fixed on the end wall 3, a mounting plate 412 connected to the fixing plate 411 at a preset angle, and a reinforcing plate 413 connecting the fixing plate 411 and the mounting plate 412; the fixed pipe clamp 42 is installed on the fixing plate 411.

[0046] The fixing plate 411 is provided with mounting holes. When installing, the fixing plate 411 is attached to the mounting member 6 welded on the end wall 3, so that the mounting holes of the fixing plate 411 and the holes on the mounting member 6 are aligned, and then the fixing plate 411 and the mounting member 6 are fixed by fasteners. In this embodiment, the fixing plate 411 and the mounting plate 412 are integrally formed.

[0047] from Figure 3 From the perspective of FIG. 4 , the fixing plate 411 and the mounting plate 412 are arranged at 90°.

[0048] The reinforcing plate 413 is welded between the fixing plate 411 and the mounting plate 412 to increase the strength and stability of the fixing plate 411 and the mounting plate 412 .

[0049] In addition, the edges of each fixed pipe clamp 42 are polished into rounded corners to prevent the edges from scratching the cables and operators during the production process.

[0050] The aforementioned frame 4 is made of stainless steel and is manufactured by sheet metal processing and welding processing. By relying on the frame 4, the T-shaped cable terminal 2 is fastened and fixed.

[0051] In order to prevent maintenance personnel from stepping on the T-shaped cable terminal 2 when climbing on the roof to check the high-voltage cable 1, a protective cover 5 is installed after the high-voltage cable 1 is installed and fixed on the T-shaped cable terminal 2. Figure 7 and Figure 8 The protective cover 5 in this embodiment includes: a first cover plate 51 and a second cover plate 52; the first cover plate 51 is fixed on the end wall 3, and the second cover plate 52 is fixed on the first cover plate 51; the first cover plate 51 and the second cover plate 52 jointly cover the T-type cable terminal 2; the first cover plate 51 is also provided with a through hole 512 for the high-voltage cable to extend out.

[0052] The first cover plate 51 is provided with a mounting hole, through which the second fastener 43 passes and is screwed and fixed to the mounting member 6 .

[0053] In order to reduce the weight of the protective cover 5, the first cover plate 51 and the second cover plate 52 are both made of aluminum plate material and are manufactured through sheet metal processing and welding processing.

[0054] In addition, after the second cover plate 52 is welded and fixed on the first cover plate 51 , the upper sides of the first cover plate 51 and the second cover plate 52 are both sloped.

[0055] Reference Figure 7 A weight-reducing hole 511 is provided on the first cover plate 51 .

[0056] The T-type cable terminal of this embodiment can realize the insulation and discharge of the breakpoints of the high-voltage cable 1 and the cable at the breakpoints during the production. The T-type cable terminal 2 installation device realizes the reliable and stable installation of the T-type cable terminal 2.
