[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", and "setting" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood in specific circumstances. In addition, in the description of the utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0018] Example 1, please refer to Figure 1-2 The utility model provides an embodiment: a data transmission terminal for smart grid, including a data transmission terminal body 1 and a cable 2. The specific structure of the data transmission terminal body 1 is the prior art and will not be described here. The data collected by the field instrument can be transmitted to the power monitoring center in real time to realize the unified monitoring and distributed management of the field instrument. The GPRS network can provide a simple and efficient communication transmission means for the field instrument system. The cable 2 can be used to connect an antenna or a power adapter. The two sides of the data transmission terminal body 1 are fixed with a mounting part 101, and the mounting part 101 is provided with a mounting hole, and the mounting part 101 can be fixed to the work place by bolts.

[0019] Furthermore, four limit posts 102 of the same length are arranged on the back of the data remote transmission terminal body 1. When assembled, the limit posts 102 abut against the installation plane, so that a gap is reserved between the back of the data remote transmission terminal body 1 and the installation plane to facilitate air flow and thus facilitate heat dissipation of the equipment.

[0020] A winding mechanism 3 for winding the cable 2 is provided on the side wall of the data remote transmission terminal body 1, and the winding mechanism 3 includes at least two support rods 301 fixed on the same side of the data remote transmission terminal body 1 and limit plates 302 respectively arranged at one end of the support rods 301 away from the data remote transmission terminal body 1, and the limit plates 302 are used to limit the cable 2. In this embodiment, two support rods 301 are provided, which are respectively arranged at the upper and lower ends of the same side of the data remote transmission terminal body 1. Winding the cable 2 on the two support rods 301 can reduce the overall volume.

[0021] In this embodiment, the support rod 301 is a columnar structure of fixed length, and a positioning mechanism 4 for fixing the cable 2 is provided on the data transmission terminal body 1 between the two support rods 301. The positioning mechanism 4 includes a threaded tube 401 fixed on the outer wall of the data transmission terminal body 1 and a threaded rod 402 threadedly connected to the threaded tube 401. One end of the threaded rod 402 extends to the outside of the threaded tube 401 and is fixed with a pressure plate 403. The pressure plate 403 is used to press the cable 2 wound on the winding mechanism 3 on the side wall of the data transmission terminal body 1 for fixation. The pressure plate 403 is rotated to move the threaded rod 402 inside the threaded tube 401. The distance between the pressure plate 403 and the side wall of the data transmission terminal body 1 is adjusted, so that the cable 2 can be pressed against the side wall of the data transmission terminal body 1, which plays a limiting role and prevents the cable 2 from spreading.

[0022] In this embodiment, two winding mechanisms 3 are provided, which are respectively arranged on both sides of the data remote transmission terminal body 1, so that two cables 2 can be wound up at the same time.

[0023] Example 2, please refer to Figure 3 The difference between this embodiment and embodiment 1 is that the support rod 301 includes an outer tube 3011 fixedly connected to the data remote transmission terminal body 1, an inner rod 3012 movably plugged into the outer tube 3011, a baffle 3014 fixed to one end of the inner rod 3012 and a return spring 3013 for pushing the inner rod 3012 into the outer tube 3011, the baffle 3014 is located inside the outer tube 3011, one end of the return spring 3013 abuts against the baffle 3014, and the other end abuts against the inner side wall of the outer tube 3011, and one end of the outer tube 3011 is penetrated by a through hole adapted to the inner rod 3012, and the size of the through hole is smaller than that of the baffle 3014. The size of the cable 2 is shown in FIG. 2 , one end of the inner rod 3012 extends to the outside through the through hole and is fixedly connected to the limit plate 302. After the cable 2 is connected to the data transmission terminal body 1, the excess length can be wound around the outside of the two support rods 301. The limit plate 302 plays a limiting role. After winding for multiple layers, the limit plate 302 is pushed to move outward, and then the baffle 3014 is driven to compress the return spring 3013 outward. Under the elastic support of the return spring 3013, the cable 2 is pressed tightly against the outer wall of the data transmission terminal body 1 to prevent the cable 2 from spreading. When in use, the cable 2 can also be wound around a single support rod 301, and multiple cables 2 can be stored at the same time.
