[0057] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers refer to the same elements throughout the drawings. The following exemplary embodiments are not intended to represent all implementations consistent with the present application. Rather, they are merely examples consistent with some aspects of the present application as detailed in the appended claims.

[0058] The terms "first", "second", "third", "fourth" and the like in the description and in the claims of the present application, and above-mentioned drawings, if any, are used to distinguish between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of the terms so construed can be interchanged, where appropriate, to describe the embodiments of the present application described herein in other than the order described. Furthermore, the terms "comprise" and "include", and any variation thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or apparatus that comprises a list of steps or units can not necessarily be limited to those steps or units that are clearly recited, but can include other not explicitly recited steps or units inherent to such process, method, product or apparatus.

[0059] As mentioned in the background section, the wire slot end is generally equipped with a gland or rubber sheath at the wire hole to seal the cable and the wire hole, and the hole diameter of the wire hole matches the outer diameter of the corrugated pipe. During the field wiring process, the number of wires out of the wire slot end may need to be temporarily increased, but the number of wire holes on the existing end plate is determined. In the case of full wiring inside the corrugated pipe, it is not possible to pass the newly added cable, and a larger size corrugated pipe needs to be selected. At this time, it is necessary to re-drill or re-bore, and the existing wire slot needs to be returned to the factory for processing, which affects the wiring progress. In addition, after re-drilling or re-boring, the original sealing element cannot be matched and needs to be reconfigured.

[0060] In view of the above problems existing in the prior art, the present application provides a wire slot structure and a locomotive. The wire slot structure provided by the present application comprises a wire slot assembly, at least one wire fixing member and at least one compression assembly. An installation cavity is arranged in the wire slot assembly to accommodate the cable, and a first installation opening is formed in the end portion of the wire slot assembly and communicates with the installation cavity. The wire fixing member is inserted into the first installation opening, and a second installation opening is formed in the wire fixing member to allow the cable to enter and exit the installation cavity. The compression assembly is connected to the wire slot assembly, and at least part of the compression assembly is arranged in the first installation opening. The wire fixing member is compressed by the compression assembly, and the first installation opening is closed by the wire fixing member and the compression assembly. By increasing or decreasing the number of wire fixing members, the arrangement requirements of more or fewer cables can be met, which is beneficial to standardized and modularized production and facilitates field wiring.

[0061] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described in detail in some examples.

[0062] Please refer to Figures 1-4 The wire slot structure provided by the embodiments of the present application comprises a wire slot assembly 100, at least one wire fixing member 200 and at least one compression assembly 300.

[0063] The wire slot assembly 100 has a mounting cavity 101 for accommodating the cable, and the wire slot assembly 100 has a first mounting opening 102 at the end thereof, which is in communication with the mounting cavity 101.

[0064] The wire fixing part 200 is inserted into the first mounting opening 102, and the wire fixing part 200 has a second mounting opening 201, which is used for the cable to enter and exit the mounting cavity 101.

[0065] The compression assembly 300 is connected to the wire slot assembly 100, and at least part of the compression assembly 300 is located in the first mounting opening 102.

[0066] The compression assembly 300 is configured to compress the wire fixing part 200 and jointly seal the first mounting opening 102 with the wire fixing part 200.

[0067] The cable in the embodiment can be a power line, a communication line, a signal line, etc., which usually has a single core or multiple cores and a protective layer on the outer layer.

[0068] The wire slot assembly 100 in the embodiment is used for placing the cable and related components, and has a generally long and strip-shaped shell structure, which can be spliced by multiple plates or integrally formed. One side of the wire slot assembly 100 can be connected to a wall, a cabinet, etc. by screwing, clamping, bonding, etc. such as the side wall in a vehicle.

[0069] The wire slot assembly 100 has a mounting cavity 101, which is convenient for placing the cable. The wire slot assembly 100 has a first mounting opening 102 at the end thereof, which is a long slot opening. The first mounting opening 102 is in communication with the mounting cavity 101, and the cable can be inserted into and out of the first mounting opening 102 to be electrically connected to the nearby electrical equipment. The first mounting opening 102 is also convenient for mounting a part for fixing and sealing the cable.

[0070] The wire fixing part 200 in the embodiment is used for positioning the cable or the protective sleeve, and can have a block or plate structure. The wire fixing part 200 has a second mounting opening 201, which is a circular opening and is used for inserting the cable. The second mounting opening 201 can be made into various specifications according to different thicknesses of the cable. On the one hand, the cable can be directly inserted into the second mounting opening 201, and the sealing is ensured by the tight fit therebetween. On the other hand, the protective sleeve can be first inserted into the second mounting opening 201, and then the cable is inserted into the protective sleeve, and the sealing is ensured by the tight fit between the protective sleeve and the second mounting opening 201.

[0071] The compression assembly 300 in the embodiment is used to compress the wire fixing part 200, which is to prevent the wire fixing part 200 from moving freely and to seal the first mounting port 102. The compression assembly 300 can be composed of an assembly with a telescopic function, which is connected to the wire slot assembly 100, and at least part of the compression assembly 300 is located in the first mounting port 102.

[0072] Specifically, as shown in Figure 1 the wire slot assembly 100 is fixed first, one wire fixing part 200 is inserted into the first mounting port 102, or a plurality of wire fixing parts 200 are inserted side by side into the first mounting port 102, according to the number of cables, and then the cables are inserted into the second mounting port 201 and the mounting cavity 101 correspondingly. The cable part outside the wire slot assembly 100 is electrically connected to the electrical equipment, and the compression assembly 300 is adjusted to compress the wire fixing part 200 to prevent it from moving freely and loosening. At the same time, the compression assembly 300 and the wire fixing part 200 jointly seal the first mounting port 102, which plays a sealing role.

[0073] It can be understood that, compared with the aperture, number and position of the existing wire slot end through-hole, the application of the wire slot structure in the embodiment can meet the arrangement requirements of more or less cables by increasing or reducing the number of wire fixing parts 200, can select the wire fixing part 200 with a corresponding aperture according to the thickness of the cable, and can appropriately adjust the position of the wire fixing part 200 in the first mounting port 102, so as to balance the flexible wiring and sealing requirements, facilitate standardized and modular production, and make wiring more convenient.

[0074] Therefore, the wire slot structure provided in the embodiment of the application includes a wire slot assembly 100, at least one wire fixing part 200 and at least one compression assembly 300. The mounting cavity 101 is arranged in the wire slot assembly 100 to accommodate the cable, the first mounting port 102 is arranged at the end of the wire slot assembly 100 and communicates with the mounting cavity 101, the wire fixing part 200 is inserted into the first mounting port 102, the second mounting port 201 is arranged on the wire fixing part 200 to allow the cable to enter and exit the mounting cavity 101, the compression assembly 300 is connected to the wire slot assembly 100, and at least part of the compression assembly 300 is arranged in the first mounting port 102. The wire fixing part 200 is compressed by the compression assembly 300, and the first mounting port 102 is jointly sealed by the compression assembly 300 and the wire fixing part 200. The number of wire fixing parts can be increased or reduced to meet the arrangement requirements of more or less cables, which facilitates standardized and modular production and makes on-site wiring more convenient.

[0076] The slider 320 is slidingly arranged on the support 310. The driving slider 320 moves towards the wire fixing part 200 and abuts against the wire fixing part 200, so that the support 310, the slider 320 and the wire fixing part 200 jointly seal the first installation opening 102.

[0077] Specifically, as shown in Figure 3 The support 310 is used for mounting the slider 320, which can be a block, a shell or the like. The support 310 is arranged in the first installation opening 102 and abuts against part of the inner wall of the first installation opening 102.

[0078] The slider 320 is used for sliding to realize the expansion and contraction of the whole compression assembly 300, which can be a block, a plate or the like. The slider 320 can be slidingly connected to the support 310 through other components, or directly connected to the support 310.

[0079] It should be noted that when the slider 320 slides to the maximum limit position, it is possible not to be separated from the support 310, so as to avoid forming a gap and not playing a sealing role. In addition, the cavity between the slider 320 and the support 310 can be sealed by part of the inner wall of the first installation opening 102.

[0080] Further, in the embodiment, the support 310 includes a mounting plate 311 and at least one baffle 312. The baffle 312 is connected to the mounting plate 311.

[0085] Further, in the embodiment, the support 310 further comprises a protruding part 313, which is connected to the mounting plate 311 on the side away from the baffle 312.

[0086] The wire slot assembly 100 has a positioning hole 103 matched with the protruding part 313, and the protruding part 313 is inserted into the positioning hole 103.

[0087] The mounting plate 311 has a first mounting hole 3111 matched with the fastener 330, and the first mounting hole 3111 penetrates the protruding part 313.

[0088] The fastener 330 is inserted into the first mounting hole 3111 and extends out of the wire slot assembly 100.

[0089] Specifically, as shown in Figure 2 , Figure 3 The protruding part 313 can be a square structure, which is connected to the mounting plate 311 on the side away from the baffle 312.

The fastener 330 has matching external threads, and the fastener 330 is screwed with the first mounting hole 3111. The end of the fastener 330 is rotationally connected with the sliding block 320 or abuts against the sliding block 320. When the fastener 330 is rotated, such as around the X-axis, the fastener 330 can push the sliding block 320 to slide, such as along the X-axis. Figure 1 Figure 1
