Description

Technical Field

[0001] This utility model belongs to the field of surge protector technology, and in particular relates to a full-mode surge protector for railway signals with status indication. Background Technology

[0002] The railway signaling system is the "brain" and "nerve center" of modern railway transportation. It is responsible for directing train operation, controlling switch switching, ensuring the clearing of sections, implementing block signaling, and providing train operation permits. As the railway signaling system becomes increasingly digital, networked, and intelligent, and the equipment integration is higher, the requirements for surge protection are becoming increasingly stringent. It is recognized that differential mode surges are ubiquitous and destructive in signal transmission lines, especially in scenarios with long-distance cables and potential differences between different grounding bodies. In order to protect these critical signaling devices from surge damage, surge protectors must be installed at their connections with the external environment (power lines, signal lines, communication lines, rails, etc.).

[0003] The third paragraph: Referring to the aforementioned existing technologies, identify the shortcomings of these technologies (write your own explanation). Therefore, we provide a full-mode surge protector for railway signals with status indication to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a full-mode surge protector for railway signals with status indication. By using indicator lights, the status of the indicator lights can be used to directly determine whether the protector body is damaged. At the same time, the movable cooperation between the upper and lower mounting plates facilitates the disassembly of the base plate for subsequent replacement or repair of the structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a full-mode surge protector for railway signals with status indication, including a base plate and multiple protector bodies that are attached to each other inside the recesses of the base plate; an interface two is opened in the middle of the lower end face of the base plate, and an interface one is opened at the position of each group of protector bodies on the upper end face of the base plate. An indicator light is set on the upper end face of the base plate behind each group of interface one. An upper hanging plate is bolted to the upper part of the rear end face of the base plate, and a lower hanging plate is symmetrically arranged above and below the upper hanging plate on the lower part of the rear end face of the base plate. A locking plate is bolted to the base plate directly below the lower hanging plate. A spring is set between the lower hanging plate and the locking plate. Multiple abutment holes are opened on the front end face of the base plate, which are respectively connected to the interior of the corresponding interface one and interface two. Each abutment hole is spirally provided with a progressive screw.

[0007] The present invention is further configured such that an insertion interface is provided on the upper and lower surfaces of the substrate recess at the positions corresponding to the protector body, and an insulating strip that slides in the insertion interface is fixed on the upper and lower surfaces of the protector body. An electric contact strip that slides in the insertion interface is fixed on the upper and lower surfaces of each group of protector bodies located behind the insulating strip.

[0008] The present invention is further configured such that a plurality of dispensing ports are opened inside the substrate located above the protector body, each dispensing port being connected to the interior of the interface, and each dispensing port being connected to the interior of the corresponding plug-in interface, and each dispensing port being provided with a current-distributing piece that is electrically connected to the contact strip.

[0009] The present invention is further configured such that a general assembly port is provided inside the substrate located below the protector body, which is connected to the interior of the second interface, and the general assembly port is connected to the interior of the corresponding multiple plug interfaces. The interior of the general assembly port is provided with a general electrical piece that is electrically connected to multiple contact strips.

[0010] The present invention is further configured such that an insertion interface is provided on the upper surface of the substrate located directly behind each interface, an annular groove is provided on the inner wall of the insertion interface, an electrical socket is fixed on the lower end of the indicator light and inserted into the position inside the insertion interface, and a rubber ring is fixed on the surface wall of the electrical socket in the annular groove.

[0011] The present invention is further configured such that each plug-in interface has a vertical hole at its bottom that communicates with the interior of the corresponding dispensing port, and a metal rod is provided inside the vertical hole, one end of which is inserted into the electrical socket, and the other end of the metal rod is electrically connected to the distributor plate.

[0012] The present invention is further configured such that a pull plate is provided on the lower end face of the locking plate, and through holes are provided on the upper end face of the locking plate at the positions corresponding to the springs. A moving rod is fixed on the lower end face of the lower hanging plate, passing through the springs and the through holes, and the lower end of the moving rod is connected to the pull plate by bolts.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model inserts the electrical socket at the lower end of the indicator light into the corresponding socket, so that the metal rod is inserted into the electrical socket. Therefore, after the distributor is powered on, the indicator light will also be powered on. Thus, when the device is powered on and working normally, the indicator light used in it will be lit normally. When the single protector body is damaged, the indicator light connected to it will also lose power and cannot light up. This allows the protector body to be directly judged as damaged based on the status of the indicator light.

[0015] 2. This utility model controls the lower hanging plate to move away from the upper hanging plate, thereby increasing the distance between the lower hanging plate and the upper hanging plate. When the distance between the lower hanging plate and the upper hanging plate is greater than the external track, the lower hanging plate and the upper hanging plate can be removed from the external track, which facilitates the disassembly of the base plate and the replacement or repair of the subsequent structure.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Please see Figures 1 to 8 This utility model is a full-mode surge protector for railway signals with status indication. By using the indicator light 4, the status of the indicator light 4 can be used to directly determine whether the protector body 2 is damaged. At the same time, the movable cooperation between the upper hanging plate 5 and the lower hanging plate 6 facilitates the disassembly of the base plate 1 for subsequent replacement or repair of the structure.

[0030] Specifically, the substrate 1 and multiple protector bodies 2 are attached to the recesses inside the substrate 1; an interface 2 103 is provided in the middle of the lower end face of the substrate 1, and an interface 1 101 is provided on the upper end face of the substrate 1 corresponding to the position of each group of protector bodies 2. An indicator light 4 is provided on the upper end face of the substrate 1 behind each group of interface 1 101. Multiple dispensing ports 106 are provided inside the substrate 1 above the protector bodies 2, each dispensing port 106 is connected to the interior of the interface 1 101, and each dispensing port 106 is connected to the interior of the corresponding insertion port 104. Each dispensing port 106 is provided with a current distribution piece 7 that is electrically connected to the contact strip 202. A general assembly port 108 is provided inside the substrate 1 below the protector bodies 2, which is connected to the interior of the interface 2 103. The assembly port 108 is connected to the interior of the corresponding multiple plug-in interfaces 104. The interior of the assembly port 108 is provided with a main electrical piece 8 that is electrically connected to multiple contact strips 202. The upper and lower surfaces of the recess of the substrate 1 are provided with plug-in interfaces 104 at the positions corresponding to the protector body 2. The upper and lower surfaces of the protector body 2 are fixed with insulating strips 201 that slide in the plug-in interfaces 104. The upper and lower surfaces of each group of protector bodies 2 located behind the insulating strips 201 are fixed with contact strips 202 that slide in the plug-in interfaces 104. The lower end face of the indicator light 4 is fixed with an electrical socket 401 that is inserted into the interior of the plug-in interface 104. The interior of the vertical hole 107 is provided with a metal rod 102 that is inserted into the electrical socket 401 at one end, and the other end of the metal rod 102 is electrically connected to the distributor piece 7.

[0031] The operation process of this embodiment is as follows: Using the above-described structure, multiple protector bodies 2 are installed in the recessed position of the substrate 1. This causes the insulating strip 201 and contact strip 202 on each protector body 2 to move into the corresponding insertion interface 104. At this time, the contact strip 202 on the protector body 2 will abut against the corresponding main electrical piece 8 and the corresponding branch electrical piece 7. Therefore, the cable is inserted into the corresponding interface 101 and interface 203, which energizes the protector body 2, thereby energizing the main electrical piece 8 and the branch electrical piece 7. When power is supplied, the electrical socket 401 at the lower end of indicator light 4 is inserted into the corresponding plug interface 104, and the metal rod 102 is inserted into the electrical socket 401. Therefore, after the power distribution piece 7 is powered on, indicator light 4 will also be powered on. Thus, when the device is powered on and working normally, the indicator light 4 used in it is in a normal lit state. When the single protector body 2 is damaged, the indicator light 4 connected to it will also lose power and cannot light up. It can be realized that the state of indicator light 4 can be used to directly determine whether the protector body 2 is damaged.

[0032] An upper hanging plate 5 is bolted to the upper part of the rear end face of the substrate 1, and a lower hanging plate 6 is symmetrically arranged above and below the upper hanging plate 5 at the lower part of the rear end face of the substrate 1. A locking plate 601 bolted to the substrate 1 is arranged directly below the lower hanging plate 6, and a spring 603 is arranged between the lower hanging plate 6 and the locking plate 601.

[0033] With the above-described structure, when installing the substrate 1, the upper hanging plate 5 and the lower hanging plate 6 are hung on the corresponding external rails. This allows for the installation of the substrate 1. When it is necessary to quickly remove the substrate 1 from the external rails, the lower hanging plate 6 can be moved away from the upper hanging plate 5, thereby increasing the distance between the lower hanging plate 6 and the upper hanging plate 5. When the distance between the lower hanging plate 6 and the lower hanging plate 6 is greater than the external rails, the lower hanging plate 6 and the upper hanging plate 5 can be removed from the external rails, facilitating the disassembly of the substrate 1 and subsequent replacement or repair of the structure. When the lower hanging plate 6 moves, it compresses the spring 603. Therefore, when the upper hanging plate 5 and the lower hanging plate 6 are hung on the external rails, the upper hanging plate 5 is directly hung on the external rails, while the lower hanging plate 6 is pushed by the spring 603 to connect with the bottom of the external rails, thus ensuring that the substrate 1 is stably installed on the external rails.

[0034] Furthermore, the front end face of the substrate 1 is provided with a plurality of abutment holes 109 that are respectively connected to the interior of the corresponding interface 101 and interface 2 103. Each abutment hole 109 is spirally provided with a progressive screw 3. In order to ensure that the cable is stably in the interface 101 and interface 2 103, the progressive screw 3 can be controlled to rotate in the abutment hole 109, so that the progressive screw 3 clamps the cable in the interface 101 and interface 2 103, ensuring that the cable is stably connected to the distributor plate 7 and the main plate 8.

[0035] Example 2

[0036] Please see Figure 2 and Figure 3 Based on Example 1, the lower hanging plate 6 is moved by the pull plate 604, which facilitates the control of the lower hanging plate 6.

[0037] Specifically, a pull plate 604 is provided on the lower end face of the locking plate 601, and through holes 602 are provided on the upper end face of the locking plate 601 at the positions corresponding to the spring 603. A moving rod 605 is fixed on the lower end face of the lower hanging plate 6, passing through the spring 603 and the through hole 602, and the lower end of the moving rod 605 is connected to the pull plate 604 by bolts.

[0038] The operation process of this embodiment is as follows: With the above structure, in order to facilitate the control of the movement of the lower hanging plate 6, the user can control the pull plate 604 to move downward. The pull plate 604 will slide in the through hole 602 through the moving rod 605, and then the moving rod 605 will control the lower hanging plate 6 to move towards the locking plate 601.

[0039] Example 3

[0040] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8 Based on Example 1, the rubber ring 402 is used to hold the indicator light 4 in the ring groove 105 to ensure that the indicator light 4 is stably assembled on the upper end face of the substrate 1.

[0041] Specifically, each of the substrates 1 located directly behind each interface 101 has an insertion interface 104 on its upper surface. The inner wall of the insertion interface 104 has an annular groove 105. The surface of the electrical socket 401 is fixed with a rubber ring 402 in the annular groove 105. Each insertion interface 104 has a vertical hole 107 at its bottom that communicates with the interior of the corresponding dispensing port 106.

[0042] The operation process of this embodiment is as follows: When the electrical socket 401 is inserted into the corresponding plug interface 104 through the above structure, the rubber ring 402 on the surface of the electrical socket 401 will be stuck in the ring groove 105. The ring groove 105 limits the rubber ring 402, thereby ensuring that the indicator light 4 is stably assembled on the upper surface of the substrate 1.
