[0041] like Figure 4~Figure 5 As shown, Figure 4 This is a schematic diagram of the structure of the upper housing 1 in the embodiment of the present application; Figure 5 It is a schematic diagram of the structure of the lower shell 2 in the embodiment of the present application.

[0042] In some embodiments of the present application, the upper shell 1 includes a first side panel and a second side panel connected to each other, the upper mortise structure 11 is arranged at the end of the first side panel away from the second side panel, and the upper tenon structure 12 is arranged at the end of the second side panel away from the first side panel.

[0043] In some embodiments of the present application, the lower shell 2 includes a third side panel and a fourth side panel connected to each other, the lower mortise structure 22 is arranged at the end of the third side panel away from the fourth side panel, and the lower tenon structure 21 is arranged at the end of the fourth side panel away from the third side panel.

[0044] In this embodiment, the first side panel is the right side panel, and the second side panel is the top panel. The downward edge of the first side panel has one or more recessed notches, namely, an upper mortise structure 11, and the inner contour of the notch is wide at the top and narrow at the bottom. The left edge of the second side panel has one or more protruding bumps, namely, an upper tenon structure 12, and the outer contour of the bumps is narrow at the top and wide at the bottom.

[0045] The third side panel is the left side panel and the fourth side panel is the bottom panel. The upward edge of the third side panel has one or more recessed notches, namely the lower mortise structure 22, and the inner contour of the notches is wide at the top and narrow at the bottom. The right edge of the fourth side panel has one or more protruding bumps, namely the lower tenon structure 21, and the outer contour of the bumps is narrow at the top and wide at the bottom.

[0046] The inner contour of the upper mortise structure 11 matches the outer contour of the lower mortise structure 21 , the outer contour of the upper mortise structure 12 matches the inner contour of the lower mortise structure 22 , the lower mortise structure 21 is embedded with the upper mortise structure 11 , and the upper mortise structure 12 is embedded with the lower mortise structure 22 .

[0047] In some embodiments of the present application, the first side panel and the second side panel are perpendicular to each other, the third side panel and the fourth side panel are perpendicular to each other, and the second side panel and the fourth side panel are arranged opposite to and in parallel.

[0048] In some embodiments of the present application, the printed circuit board 3 and the second side plate and the fourth side plate are parallel to each other.

[0049] In this embodiment, the first side plate, the second side plate, the third side plate and the fourth side plate form a cubic structure with two ends open, and the printed circuit board 3 is arranged in an I-shape between the top plate and the bottom plate.

[0050] In some embodiments of the present application, the lower shell 2 also includes two limit retaining walls 23, and the two limit retaining walls 23 are respectively arranged on both sides of the fourth side panel. The width of the first side panel in the upper shell 1 is greater than the width of the second side panel. There is a step-shaped limit interface 13 at the junction of the first side panel and the second side panel, and the second side panel is embedded between the two limit retaining walls 23.

[0051] In this embodiment, the mortise and tenon structure mainly provides the limit in the height direction. The limit retaining wall 23 is embedded in the limit interface 13, that is, the two limit retaining walls 23 surround the second side plate, and the lower shell 2 at least partially wraps the upper shell 1, which can achieve the limit in the width direction.

[0052] Only two parts are needed to achieve the limited fixed assembly effect between the two shells, saving costs; the mortise and tenon connection is easy to install and disassemble, and can be disassembled and assembled multiple times without affecting the effect. The device can be modularized and standardized in design, and can be used in a variety of scenarios and structures through reasonable layout.

[0053] In some embodiments of the present application, the edge of the second side panel has a soldering platform avoidance gap 14, and the soldering platform avoidance gap 14 extends along the length direction of the second side panel, and the length of the soldering platform avoidance gap 14 is less than the length of the second side panel.

[0054] In this embodiment, a welding platform avoidance notch 14 is provided on the second side plate to prevent the welder or welding robot from directly contacting the welding platform with the notch or raised portion of the workpiece during the welding operation, thereby preventing uneven welding or damage to the workpiece.

[0055] In some embodiments of the present application, the fourth side panel has a first interface groove 24 and a second interface groove 25, the first interface groove 24 and the second interface groove 25 extend along the length direction of the fourth side panel, the length of the first interface groove 24 is less than the length of the fourth side panel, the length of the second interface groove 25 is equal to the length of the fourth side panel, and the first interface groove 24 and the second interface groove 25 are respectively connected to the female interface 5 and the male interface 4.

[0056] In some embodiments of the present application, the male interface 4 and the female interface 5 both have metal pins, and the male interface 4 and the female interface 5 are electrically connected to the printed circuit board 3 through their respective metal pins.

[0057] In this embodiment, the first interface slot 24 and the second interface slot 25 of different lengths are arranged on the fourth side plate, corresponding to the female interface 5 and the male interface 4 respectively, which is a foolproof design to prevent the male interface 4 and the female interface 5 from being reversed and the lines from being connected incorrectly.

[0058] In some embodiments of the present application, the upper mortise structure 11 and the lower mortise structure 22 are recessed notches, the inner contour of the notches is trapezoidal, and the upper tenon structure 12 and the lower tenon structure 21 are protruding bumps, the outer contour of the bumps is trapezoidal.

[0059] In this embodiment, the inner contour of the notch is narrow at the opening and wide at the bottom. For example, if the first side plate in the upper shell 1 is inverted and the notch is recessed upward, the inner contour is wide at the top and narrow at the bottom. If the third side plate in the lower shell 2 is upright and the notch is recessed downward, the inner contour is narrow at the top and wide at the bottom.

[0060] Correspondingly, the outer contour of the protrusion is wider toward the inside and narrower toward the outside. Here, the inside and outside are based on the center of the two shells after alignment. For example, if the second side plate in the upper shell 1 is inverted and the protrusion is facing downward to the inner side of the shell, the outer contour is narrow at the top and wide at the bottom, while the fourth side plate in the lower shell 2 is upright and the protrusion is facing upward to the inner side of the shell, then the outer contour is wide at the top and narrow at the bottom.

[0061] The wider end of the protrusion is embedded in the bottom of the notch. Since the wider end of the protrusion cannot pass through the opening of the notch, the mortise and tenon structure completes the interlocking between the two shells in the height direction.

[0062] Compared with the prior art, the application of the embodiment of the present application can at least achieve the following beneficial effects: the embodiment of the present application designs mortise and tenon structures on the upper shell 1 and the lower shell 2 respectively, and the upper and lower shells 2 are installed with the mortise and tenon structures. The mortise and tenon do not require other fasteners, and the assembly is simple and reliable. The adapter device in this embodiment has a simple structure, and only requires the mortise and tenon structures of the upper and lower shells 2 to cooperate. It is easy to install and disassemble, does not require any structural fasteners, can improve production and installation efficiency, and is easy to maintain. The male interface 4 and the female interface 5 are connected together through the printed circuit board 3, and the male interface 4 and the female interface 5 can be completely fixed by aligning the upper and lower shells 2. By reasonably arranging and installing the mortise and tenon structure, the loosening and deformation problems of the structural parts of the serial port adapter device are effectively solved, and the structure is simple, the connection is reliable, and it is easy to realize modular standard design and mass production, reduce production costs, and fill the product gap on the market.
