Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As an embodiment of the present invention, a coupler shield, see fig. 1 and 2, comprises an upper shield 1, a lower base 2 and two side sealing plates 3, wherein the lower base 2 comprises a left plate 2-1, a bottom plate 2-2 and a right plate 2-3. The left plate 2-1 and the bottom plate 2-2 and the right plate 2-3 and the bottom plate 2-2 are connected in an integral bending way. Two ends of the upper shield 1 are respectively positioned on the left plate 2-1 and the right plate 2-3, and the edges of the left plate 2-1 and the right plate 2-3 are connected with a fixing plate 2-4 vertical to the left plate 2-1, the right plate 2-3 and the bottom plate 2-2. The side sealing plate 3 comprises a longitudinal plate 3-1 and a transverse plate 3-2, the longitudinal plate 3-1 is fixed on the fixing plate 2-4, and the transverse plate 3-2 is connected to the top of the longitudinal plate 3-1 and is lower than the bottom of the upper shield 1. The middle section of the coupler is placed in a space between the lower base 2 and the upper protective cover 1, two ends of the coupler extend out of two end openings of the upper protective cover 1, and the lower base 2 and the upper protective cover 1 are connected to form a closed space for the coupler.
