Description

Technical Field

[0001] This utility model belongs to the field of railway signal cable termination technology, specifically relating to a compact railway signal cable termination box. Background Technology

[0002] Currently, when outdoor armored cables are introduced into indoor equipment rooms in the railway system, the internal steel strip layer and aluminum sheath layer of the outdoor armored cable need to be terminated separately at the entry point, i.e., for safety grounding. However, some railway equipment rooms do not have installation space for primary termination at the entry point, so cable termination can only be performed outdoors (by leading the cable from the cable well to the surface for termination). However, there are situations where the reserved length of outdoor armored cables in the cable well is insufficient, making it impossible to lead the cable to the ground for termination; termination must be performed inside the cable well.

[0003] Utility model patent CN202020732646.X discloses a railway signal cable termination and splicing cabinet. When terminating cables, it is usually necessary to introduce the cable from the bottom of the cabinet and then lead it out from the top.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0026] Example 1: Please refer to Figures 1-3 As shown, Embodiment 1 of this utility model provides a compact cable termination box 100 for railway signaling. This termination box 100 is mainly used for termination operations of outdoor armored cables for railway lines in cable wells (please refer to the structure after the armored cables are installed). Figure 4 As shown in the figure, the steel strip layer and aluminum sheath layer inside the outdoor armored cable are terminated once to ensure the armored cable is safely grounded, and then the armored cable is introduced into the indoor equipment room.

[0027] The termination box 100 mainly consists of a termination box 10 and a box cover 20. The number of termination boxes 10 is not limited and can be one, two, three, etc. In this embodiment, the number of termination boxes 10 is one. The top of the termination box 10 is open, and the box cover 20 is used to close the top of the termination box 10. The termination box 10 and the box cover 20 together form a closed termination space, so that the various components inside are in a closed space and are not disturbed by the outside.

[0028] It should be noted that the orientations "up," "down," "left," "right," "front," and "back" in this embodiment are relative positions, not absolute positions. They can be defined according to actual needs, and their orientation can also change accordingly as the installation position and orientation of the terminal box 100 change. For ease of description, this embodiment defines the orientations "up," "down," "left," "right," "front," and "back" as follows: Figure 3 For example, in this embodiment, the up and down direction is... Figure 3 The vertical direction in the middle, and the horizontal direction in this embodiment are... Figure 3 In this embodiment, the left-right direction is perpendicular to the paper surface, while the front-back direction is perpendicular to the paper surface.

[0029] The specific structures of the end box 10 and the box cover 20 will be discussed in detail below.

[0030] Please combine Figure 5 , Figure 6 As shown, the termination box 10 mainly consists of a box body 110 and several cable management racks 140, with the cable management racks 140 installed on the box body 110. Generally speaking, the height of the box body 110 is not high, and it is best to form no more than three layers of cables inside the box body 110, such as one layer, two layers, or three layers.

[0031] The structure of the box 110 is not limited. For example, the box 110 includes a frame and a sealing plate 144, a base frame and a vertical frame, with the vertical frame mounted on the base frame. The bottom and corresponding positions around the frame are closed by the sealing plate 144. Of course, the box 110 can also be assembled from several panels.

[0032] Please combine Figure 7 As shown, the housing 110 is provided with a cable management channel 111, which runs through the cable management channel in the front-to-back direction. Cables are passed through the cable management channel 111 and can pass through it in the front-to-back direction. Furthermore, the opening of the cable management channel 111 faces upward, that is, the longitudinal cross-section of the cable management channel 111 is approximately U-shaped, allowing cables to be inserted into the cable management channel 111 from the open end.

[0033] The front and rear ends of the cable management channel 111 are sealed by cable management racks 140. The number of cable management racks 140 is not limited, but it is best to seal both ends of the cable management channel 111. Of course, it is also possible for several cable management racks 140 to seal part of both ends of the cable management channel 111, while the other part of the cable management channel 111 is sealed by other structures.

[0034] Please combine Figure 8 As shown, each cable management rack 140 includes two independent units. Each unit has a corresponding latch that connects to form an end hole 141. For example, each cable management rack 140 may have an upper unit 145 and a lower unit 146. The upper unit 145 has an upper latch, and the lower unit 146 has a lower latch. The upper unit 145 is located above the lower unit 146, with the upper latch opening downwards and the lower latch opening upwards. The upper and lower latches are opposite each other and connect to form a complete hole, which is the end hole 141. The shape of the end hole 141 is not limited; it can be a square hole, a round hole, a hexagonal hole, etc., but a round hole is preferred. Of course, the upper unit 145 and the lower unit 146 may not overlap, or they may partially overlap. If the upper unit 145 and the lower unit 146 partially overlap, then the upper and lower latches partially overlap. Both the upper and lower latches can be U-shaped and connect to form a circular hole.

[0035] Each unit is detachably connected to the housing 110 at both ends. The detachable connection between the unit and the housing 110 is not limited, such as snap-fit ​​or fastening. In this embodiment, the unit and the housing 110 are detachably connected by threaded fasteners.

[0036] The termination box 10 forms a termination cavity. Within this cavity, cable termination operations are performed, and various cables need to be combined. Therefore, the termination box 10 can be divided into two chambers: a termination chamber 120 and a junction chamber 130. The termination chamber 120 is used to install the main cable circuit, and the junction chamber 130 is used to install the auxiliary bypass circuit. The termination chamber 120 and the junction chamber 130 are arranged side-by-side, and they can be connected or separated.

[0037] Cable management channel 111 and cable management rack 140 form a termination chamber 120, where workers can perform termination operations and install steel tape busbars 121, aluminum sheathed busbars 122, etc. Cable termination and the installation of steel tape busbars 121 and aluminum sheathed busbars 122 are common knowledge, and will not be elaborated upon here. This setup standardizes cable termination, ensuring consistent spacing, height, and level at each cable termination point, resulting in a neater and more standardized appearance, facilitating maintenance.

[0038] The junction box 130 has outlet holes facing different directions around its perimeter, for example, with Figure 3 Taking the orientation as an example, the junction box 130 is equipped with outlet holes in the front, back and left directions. The number of outlet holes in each direction is unlimited, and can be one, two or three, etc. The staff can decide the outlet direction according to the actual situation to avoid the situation of wire tangling. Unused outlet holes can be sealed or left unsealed with plates or other materials.

[0039] Of course, in other embodiments, the end chamber 120 may also be a single chamber.

[0040] Accordingly, the junction box 130 is equipped with a steel strip main bus 131, an aluminum sheath main bus 132, a safety grounding bus 133, and a data acquisition sensor. The steel strip main bus 131 needs to be electrically connected to multiple steel strip bus 121, the aluminum sheath main bus 132 needs to be electrically connected to multiple aluminum sheath bus 122, the safety grounding bus 133 is used to connect to the grounding wire, and the data acquisition sensor is used to collect various data from the cable to promptly understand the status of the cable termination. The structure, style, and connection method of the steel strip main bus 131, aluminum sheath main bus 132, safety grounding bus 133, and data acquisition sensor can all adopt existing technologies and will not be elaborated here. Of course, the use of the steel strip main bus 131 and aluminum sheath main bus 132 can be selected based on the site conditions.

[0041] Separating the main cable circuit and the auxiliary bypass circuit can avoid mutual interference and facilitate installation and identification.

[0042] The termination box 100 in this embodiment can be installed on the ground or on a wall. In order to fix the termination box 100 after the cable is terminated, a connecting hole plate 112 can be provided at the bottom of the termination box 10. The connecting hole plate 112 is provided with through holes, which can be various styles such as round holes, square holes, and oblong holes. Threaded fasteners such as bolts and screws can be inserted into the through holes. The connecting hole plate 112 is configured to be fixed to the ground or wall by threaded fasteners, that is, the threaded fasteners pass through the through holes and are fixed to the ground or wall.

[0043] Generally speaking, the thickness of a single unit is usually not too large, which results in the edge of the termination hole 141 being relatively sharp. If the termination hole 141 bears the weight of the cable, the edge of the termination hole 141 may tear the cable. Therefore, in this embodiment, the following solutions can be adopted, but are not limited to: the termination box 10 also includes an auxiliary frame 142, which is used to support the cable.

[0044] The auxiliary frame 142 can be any shape, such as a strip, a rod, or a strip with this side. The auxiliary frame 142 is detachably mounted laterally within the housing 110. It is adjacent to the cable management rack 140, and the top surface of the auxiliary frame 142 corresponds to the lower end of the termination hole 141. The top surface of the auxiliary frame 142 can be equal to, slightly higher than, or slightly lower than the lower end of the termination hole 141. This means that after the cable enters the termination cavity through the termination hole 141, the bottom of the cable is supported by the auxiliary frame 142. This arrangement ensures that the cable passing through the termination box 100 is primarily supported by the auxiliary frame 142, preventing the cable from being scratched by the edge of the termination hole 141.

[0045] Since the number of cables in each cable well is unlimited, for example, if the number of cables is less than the number of termination holes 141, it may not be necessary to use all of the termination holes 141. To prevent mice or debris from entering the termination box 100, it is preferable to seal the unused termination holes 141. Therefore, in this embodiment, the cable management rack 140 also includes several sealing plates 143. The sealing plates 143 are detachably connected to the unit and are used to seal the termination holes 141. Of course, in other embodiments, it is also possible not to provide sealing plates 143.

[0046] The shape of the sealing plate 143 is not limited, such as a circular plate or a square plate. The installation position of the sealing plate 143 is not limited, as long as it can close the end hole 141. In this embodiment, the cable management rack 140 includes a lower unit 146 and an upper unit 145. The adjacent ends of the lower unit 146 and the upper unit 145 are staggered and stacked. The sealing plate 143 is attached to the lower unit 146 and partially embedded in the slot of the upper unit 145.

[0047] The connection method between the sealing plate 143 and the unit is not limited. For example, it can be connected by magnetic adsorption, or the unit can be provided with a slot and the sealing plate 143 can be inserted into the slot. In this embodiment, at least two mounting holes are provided around the end hole 141. The sealing plate 143 and the unit are detachably connected by threaded fasteners, that is, the threaded fasteners pass through the sealing plate 143 and the mounting holes and fix the sealing plate 143 and the unit.

[0048] Furthermore, since the number of cables in each cable well is unlimited, that is, the number of layers after passing through the termination box 100 is unlimited, such as one, two, or three layers, in order to reduce the number of termination boxes 10 or termination boxes 100, each termination box 10 is usually equipped with two, three, or four layers of cable management racks 140. If the number of cables is small, only some of the cable management racks 140 may be used. The unused part can be sealed by the sealing plate 144. The sealing plate 144 and the box body 110 are detachably connected. The detachable connection method is not limited, such as snap-fit ​​or connection by threaded fasteners. The sealing plate 144 and the cable management rack 140 are stacked together, and the sealing plate 144 and the cable management rack 140 together seal both ends of the cable management channel 111. The number of sealing plates 144 and cable management racks 140 is unlimited and can be used according to actual needs. Both ends of the cable management channel 111 have at least one layer of cable management racks 140. This arrangement reduces the number of unused end holes 141 and eliminates the need to install too many sealing plates 143, making installation simpler and more convenient.

[0049] In some embodiments, to make the connection between the upper and lower cable management frames 140 more accurate and convenient, a connecting flange 147 can be provided at the far end of each of the two individual units of the same cable management frame 140. For example, the bottom end of the lower unit 146 is provided with a connecting flange 147, and the top end of the upper unit 145 is provided with a connecting flange 147, so that the connecting flange 147 of the lower unit 145 can abut against the connecting flange 147 of the upper unit 146.

[0050] Since the cable termination box 100 can be installed on the ground or on a wall, the opening direction of the cable management channel 111 is not fixed. In this embodiment, "the cable management channel 111 runs through the front and back and opens upward" means that the cable termination box 10 is installed on the ground. If the cable termination box 10 is installed on a wall, its through direction and opening direction will change accordingly.

[0051] The style of the lid is not limited, such as a thin plate structure or a thin plate structure with folded edges, etc., and the connection method between the lid and the end box 100 is not limited, such as snap-fit, plug-in, or connection by threaded fasteners, etc.

[0052] The termination box 100 provided in this embodiment typically needs to be used in conjunction with a surface monitoring system. After the cables are terminated, the lead-out wires need to be connected to the surface monitoring system, and the data sensor leads need to be connected to the data acquisition module of an external device, enabling the transmission of detected data to the external device. The underground termination mechanism, i.e., the termination box 100 after cable installation, collects data and introduces it into the surface termination control system. The data acquisition module then transmits the data to the intelligent control host. The intelligent control host can upload the processed signals to a touch screen for maintenance personnel to monitor, or it can upload them to the railway monitoring system for railway personnel to check the termination status, ensuring system operational safety. Of course, the surface monitoring system and its connection and cooperation with the terminated termination box 100 are relatively mature technologies and will not be elaborated upon here.

[0053] The method of using the terminal box 100 provided in this embodiment is as follows: Separate the terminal box 10 and the cover 20, and then fix the terminal box 10 to the ground or wall. If the cable well is deep, the terminal box 100 can also be installed on a rack. Install the lower unit 146 of the cable management bracket 140 at both ends of the cable management channel 111 onto the box 110, with the opening of the lower unit 146 facing upwards. The armored cable is placed in the cable management channel 111, and the armored cable passes through the two cable management racks 140 at both ends of the cable management channel 111 and is supported on the auxiliary rack 142. The termination operation for armored cables includes stripping, cutting, grounding, installing the termination box 10, and sealing with glue. This step is common knowledge in the field and will not be described in detail here. Following the steps described above, the armored cables on the same layer are terminated sequentially. Steel strip busbar 121, aluminum sheath busbar 122, data acquisition sensor leads, etc. are installed at the end of the same row; The upper unit 145 of the cable management rack 140 at both ends of the cable management channel 111 is installed on the box 110. The opening of the upper unit 145 is downward. The openings of the upper unit 145 and the lower unit 146 together form the end hole 141. The armored cable is passed through the end hole 141. Following the steps described above, terminate the armored cables of different layers in sequence. Connect multiple steel strip busbars 121 to the main steel strip busbar 131 in the manifold 130, connect multiple aluminum sheath busbars 122 to the main aluminum sheath busbar 132 in the manifold 130, and connect multiple data acquisition sensor leads to the data acquisition sensors in the manifold 130. If one termination box 10 cannot accommodate all the armored cables, then another termination box 10 is stacked on top of the termination box 10, and then the two termination boxes 10 are connected and fixed. Continue the above steps until all the armored cables are terminated. After all armored cables have been terminated, if the two ends of the cable management channel 111 are still not completely closed, the sealing plate 144 is connected to the box 110; if some of the termination holes 141 of the cable management rack 140 are not used, the excess termination holes 141 are closed by the sealing plate 143. Based on the actual situation, determine the outgoing direction of the line in the junction box 130, and lead the line out from the outgoing hole in the corresponding direction; The cover 20 is placed on top of the termination box 10, thereby forming a relatively enclosed space in the termination box 100 to prevent the termination part of the armored cable, the steel strip busbar 121, the data acquisition sensor, etc. from being affected by the outside world.

[0054] The above steps can be added, removed, modified, or their order adjusted as needed. For example, depending on the actual site conditions, it can be decided whether to use the steel strip main busbar 131, aluminum sheath main busbar 132, etc. If not used, the corresponding steps can be cancelled.

[0055] Example 2: Please refer to Figure 9 , Figure 10 As shown, Embodiment 2 of this utility model provides an end-forming box 100. This embodiment is an improvement on Embodiment 1, and the improvements are in the number of end-forming boxes 10 and the structure of the end-forming holes 141.

[0056] Generally, the height of the termination box 10 in the termination box 100 provided in this embodiment is not too large. If the termination box 10 is too tall, the cable management channel 111 will be too tall, making it difficult for cables to enter the channel from the top and be arranged in multiple layers. Furthermore, if the termination box 10 is too tall but the number of cables is small, only a portion of the termination box 100 can be used, resulting in a larger space occupied by the termination box 100. Therefore, in this embodiment, the number of termination boxes 10 is at least two, such as two, three, or four; three is used as an example.

[0057] Three termination boxes 10 are stacked vertically, and adjacent termination boxes 10 are detachably connected. The upper opening of the lower termination box 10 is closed by the upper termination box 10, and the upper opening of the top termination box 10 is closed by the cover 20. This arrangement allows cables to easily enter the cable management channel 111, and the number of termination boxes 10 can be determined according to the actual number of cables. The detachable connection method between two adjacent end boxes 10 is not limited, such as snap-fit. In this embodiment, the following scheme can be adopted, but is not limited to: a plurality of connection hole plates 112 are respectively provided at the upper and lower ends of the end box 10, and the corresponding connection hole plates 112 of two adjacent end boxes 10 abut against each other and are connected by threaded fasteners.

[0058] In addition, since the thickness of a single unit is generally small, usually a few millimeters, the edge of the clamp is relatively sharp, while the outer sheath of the armored cable is usually a relatively soft rubber layer. Therefore, the clamp may cut the outer sheath of the armored cable, resulting in leakage and other problems.

[0059] To improve the above problems, the following solutions can be adopted, but are not limited to: Please combine Figure 11 As shown, the bayonet is provided with an inwardly bent anti-cut edge 148. The inner side of the anti-cut edge 148 is a flat or curved surface and is configured to contact the cable. If the inner side of the anti-cut edge 148 is flat, it increases the contact area between the cable and the termination hole 141, thereby preventing the edge of the termination hole 141 from cutting the cable. If the inner side of the anti-cut edge 148 is curved, although the contact area between the cable and the termination hole 141 is still small, the edge of the termination hole 141 is not sharp and is less likely to cut the cable. Of course, in some embodiments, it is also possible not to provide an inwardly bent anti-cut edge 148 on the inner side of the bayonet.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
