[Detailed ways]

As shown in Figure 1 and Figure 2, a flexible cord switch housing includes a housing composed of a bottom shell 1 and a face shell 2, and bottom shell connecting posts 3 and face shell connecting posts 4 arranged at the four corners of the shell. There are also corresponding wire grooves and button holes 6 in the body, and through holes 7 that are respectively provided at both ends of the housing to supply power lines in and out. The connecting column 3 of the bottom case is provided with a hollow hole 31, and the wall of the hollow hole 31 is provided with a The clamping hole 32, the face shell connecting column 4 is arranged in the above-mentioned hollow hole 31, the face shell connecting column 4 is provided with a barb 41, and the outer end of the barb 41 is stuck in the clamping hole 32 on the wall of the hollow hole 31, so that , the face case connecting column 4 is stuck in the bottom case connecting post 3, thereby playing the role of connecting the bottom case 1 and the face case 2.

In the utility model, the bottom shell 1 and the face shell 2 are made of plastic injection molding, the face shell connecting column 4 is a solid body, the face shell connecting column 4 is injection molded with the surface shell 2, and the bottom shell is connected The column 3 is also injection-molded with the bottom case 1 as a whole. When fastening, only the bottom case 1 and the face case 2 need to be aligned and pressed together, which is very convenient for installation.

As shown in Figures 3 and 4, the barb 41 has one, and the barb 41 is located at the lower end side of the connecting column 4 of the face shell. The outer end is on the cylindrical surface of the connecting column 4 of the face shell, so that the connecting column 4 of the face shell will not be affected by the barb 41 when it is inserted in the hollow hole 31 on the connecting column 3 of the bottom shell. The bottom of the hollow hole 31 is an arc-shaped inclined surface 310, and the lower end of the arc-shaped inclined surface is tangent to the edge of the lower part of the clamping hole 32. The inclined surface 310 is pressed against and bent, and the degree of bending is small. At this time, the outermost end of the barb 41 on one side of the lower end of the face shell connecting column 4 snaps into the clamping hole 32 on the wall of the hollow hole 31 on the same side, realizing The fastening between the connecting column 4 of the face shell and the connecting column 3 of the bottom shell has a simple structure and is convenient for fastening.

As shown in Fig. 5 and Fig. 6, there are two barbs 41, and the two barbs 41 are formed by making a gap on the two opposite sides of the face shell connecting column 4 respectively, and the outermost ends of the two barbs 41 are On the cylindrical surface of the connecting post 4 of the face shell, like this, the connecting post 4 of the face case will not be affected by the barb 41 when it is inserted into the hollow hole 31 on the connecting post 3 of the bottom case. The two barbs 41 are located on two opposite sides of the lower end of the face shell connecting column 4 , and the clamping hole 32 vertically penetrates through the column wall of the bottom shell connecting column 3 , thereby forming two opposite clamping holes on the wall of the hollow hole 31 . The bottom of the hollow hole 31 is provided with a tapered protrusion 311, and the bottom surface of the face shell connecting column 4 is provided with an inverted "V"-shaped groove 42. The tapered protrusion 311 is inserted in the groove 42 and squeezes the above-mentioned barb 41, so that The two barbs 41 are respectively snapped into two opposite snapping holes on the wall of the hollow hole 31 to realize the engagement of the connecting column 4 of the surface shell and the connecting column 3 of the bottom shell, and the fastening is also very convenient.

As shown in Fig. 7 and Fig. 8, there are two barbs 41, and the two barbs 41 are located on two opposite sides of the middle part of the connecting column 4 of the face shell, and the barbs 41 protrude from the cylindrical surface of the connecting column 4 of the face shell. The clamping hole 32 on the wall of the hollow hole 31 vertically penetrates the column wall of the connecting column 3 of the bottom shell, thereby forming two opposite clamping holes on the wall of the hollow hole 31. When the bottom shell 1 and the surface shell 2 are fastened together, the surface shell is connected. The outermost ends of the two barbs 41 on the upper part of the column 4 squeeze the inner wall of the hollow hole 31 on the connecting column 3 of the bottom shell. Since the connecting column 3 of the bottom shell and the connecting column 4 of the surface shell are both made of plastic, they have a certain deformation capacity. In this way, the two barbs 41 on the surface shell connecting column 4 slide down along the inner wall of the above-mentioned hollow hole 31 and snap into two opposite clamping holes formed on the wall of the hollow hole 31, thus realizing the connection between the surface shell connecting column 4 and the bottom shell connecting column. 3, the structure is simple, and the buckle is also very convenient.
