[0019] It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs.

[0020] For ease of description, spatially relative terms such as "above," "above," "on the upper surface of," and "upper" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in a drawing is inverted, a device described as "above" or "on top of" another device or structure would then be positioned as "below" or "below" the other device or structure. Thus, the exemplary term "above" can include both the "above" and "below" orientations. The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0021] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for clarity, the thickness of layers and regions is exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0022] Please refer to Figures 1 to 6. An embodiment of the present invention provides a new signal trackside box, including: a box support 1 and a box 2. The box 2 is arranged on the box support 1.

[0023] Specifically, the box support 1 includes a base 11 and a back plate 12 vertically connected to the upper rear side of the base 11. The base 11 is fixed to the prefabricated cement foundation on the ground by a first bolt 3. The rear side of the box 2 is mounted on the upper front side of the back plate 12 by a second bolt 5.

[0024] A cable lock 4 is provided at the bottom of the box 2, and a grounding gasket 104, a connector 105, a ground wire 106 and an equipment grounding terminal 107 are provided inside the box 2; the cable lock 4 includes a cable terminal 102 and two gland locking nuts 103, the two gland locking nuts 103 are located inside the box 2, the cable terminal 102 is located inside and outside the box 2, a grounding gasket 104 is provided between the two gland locking nuts 103, the grounding gasket 104 is connected to the ground wire 106 through the connector 105, the ground wire 106 is connected to the equipment grounding terminal 107, and the equipment grounding terminal 107 is located on the inner wall of the box 2.

[0025] The ground wire 106 is a 2.5 mm² ground wire.

[0026] The new signal railside box of the present invention fixes the base 11 of the box bracket 1 to the prefabricated cement foundation on the ground through four pre-buried first bolts 3, and the box 2 is connected to the back plate 12 of the box bracket 1 through four second bolts 5. The iron-sheathed cable 101 is pulled apart and inserted into the box 2. The cable is about 5 cm long at the cable lock 4, and only the outer insulating sheath is pulled apart to retain the steel belt. After the cable lock 4 is tightened, the box 2 can achieve IP65 waterproof and dustproof grade. After the cable lock 4 is tightened, the grounding gasket 104 is tightly connected to the steel belt. The grounding gasket 104 is led to the equipment grounding terminal 107 in the box 2 through a 2.5mm² ground wire 106. The equipment grounding terminal 107 is connected to the section through-grounding through a 25mm² ground wire, completing the grounding of the signal railside box.

[0027] As can be seen from the above examples, the novel signal trackside box provided by the present invention uses cable glands to replace the traditional box's cable termination, protective tube fixing, ground wire connection, and glue filling processes, simplifying the installation process, shortening construction time, and improving installation efficiency. The use of grounding gaskets within the cable glands replaces the traditional box grounding method, reducing installation difficulty, improving connection security, and enhancing the box's sealing performance.
