Technical Field
[0001] The utility model relates to the field of plastic shells, in particular to a waterproof and breathable plastic shell. Background Art
[0002] A plastic housing is a device that insulates and secures terminals in place, ensuring connector intermateability and dimensional stability. It provides mechanical protection and support for the terminals, protecting them from potential corrosion in the operating environment. Data transmission between terminals generates heat during use, which, if not removed promptly, can affect data transmission efficiency. This heat removal must also ensure the housing's waterproof properties, necessitating a waterproof and breathable housing.
[0003] Most existing plastic shells are closed and lack a waterproof and breathable structure. This can cause the wires and terminals that transmit data to overheat during use, affecting not only the data transmission efficiency but also the service life of the terminals. In addition, the existing shell materials are flammable and have not undergone fireproofing treatment. If the terminal connection inside the shell is short-circuited during use, there is a risk of fire.
[0004] Therefore, those skilled in the art provide a waterproof and breathable plastic shell to solve the problems raised in the above background technology. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a waterproof and breathable plastic shell is proposed. Three parallel male plugs are fixedly arranged at the center of one side of the male shell wire end, female sockets are slidingly sleeved on the surfaces of the three male plug rods, a female shell wire end is fixedly arranged on the side of the female socket away from the male shell wire end, two rows of air holes are respectively provided on the upper end face and the lower end face of the female socket close to the female shell wire end, a cavity is provided at one end of the two rows of air holes away from the upper surface of the female socket, and a waterproof and breathable membrane is fixedly provided on the side of the cavity away from the air holes. The air holes can allow the heat generated when data is transmitted between the terminals to escape through the air holes. At the same time, the waterproof and breathable membrane can effectively prevent moisture from entering the interior of the electronic device through the air holes, protecting the internal components from being invaded by water vapor. Adding a flame retardant layer and a protective layer to the material structure of the shell not only prolongs the life of the shell, improves its durability, but also increases its safety performance.
[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: a waterproof and breathable plastic shell, comprising a male shell wire end, three male end plugs fixedly arranged in parallel at the center of one side of the male shell wire end, female end sockets slidingly sleeved on the surfaces of the three male end plugs, and a female shell wire end fixedly arranged on the side of the female end socket away from the male shell wire end;

The central axes of the female shell wire groove and the male shell wire groove are in the same straight line to ensure normal connection of the terminals.
[0017] Furthermore, the waterproof and breathable membrane is located at the upper and lower ends of the junction of the male shell wire groove and the female shell wire groove;
[0018] Through the above technical solution, after the plastic shell is fixed, the terminal connection is located at the junction of the male shell wire groove and the female shell wire groove.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0035] Reference Figure 1-6 The utility model provides an embodiment: a waterproof and breathable plastic shell, including a male shell wire end 1, three parallel male end plugs 13 are fixedly provided at the center of one side of the male shell wire end 1, and female end sockets 10 are slidingly provided on the surface of the shaft of the three male end plugs 13.

Before transmitting data, the wires of the installed terminals are fixed inside the male plastic shell and the female plastic shell, and then the male end plug 13 is aligned with the female end socket 10 and inserted to connect the internal terminals.
[0037] The material structure of the male shell wire end 1 is a protective layer 101, a flame retardant layer 102 and a base layer 103 from the outside to the inside. The material structure of the male end plug 13, the female end socket 10 and the female shell wire end 6 is the same as that of the male shell wire end 1;
[0038] Adding a protective layer 101 to the material of the plastic shell can reduce the wear of the shell, and adding a flame retardant layer 102 can improve the safety performance of the shell and avoid fire caused by short circuit.
[0039] Two rows of ventilation holes 5 are respectively formed on the upper and lower end surfaces of the female end socket 10 near the female shell wire end 6. A cavity 14 is formed on the end of the two rows of ventilation holes 5 away from the upper surface of the female end socket 10. A waterproof and breathable membrane 15 is fixedly provided inside the cavity 14 on the side away from the ventilation holes 5.
[0040] The vent holes 5 can allow the heat generated when the terminal connection is transmitting data to escape, while the waterproof breathable membrane prevents water flowing in through the vent holes 5 from entering the terminal connection.
[0041] A lock box 4 is fixedly provided at the center of the upper and lower end surfaces of the female socket 10 away from the female shell wire end 6. A lock hole 9 is opened on the lock box 4 away from the female socket 10. A lock tongue 2 is fixedly provided on the upper and lower end surfaces of the male shell wire end 1 on the side close to the male plug 13.

A lock block 3 is fixedly provided on the side of the lock tongue 2 close to the lock hole 9, and the lock block 3 is located inside the lock hole 9;
[0042] When the plastic shell is connected and fixed, the lock tongue 2 is inserted into the lock box 4, and the lock block 3 on the lock tongue 2 extends from the lock hole 9 of the lock box 4. The plastic shell is firmly fixed under the action of the support spring 16 between the lock tongue 2 and the male shell wire end 1.
[0043] A sealing groove 12 is provided at the edge of the male shell wire end 1 near the male plug 13. A protrusion 11 is fixedly provided at the edge of the female end socket 10 away from the female shell wire end 6. The protrusion 11 is located inside the sealing groove 12. The protective layer 101 is a polyurethane coating, the flame retardant layer 102 is made of brominated flame retardant, and the base layer 103 is nylon. A male shell wire groove 17 that continuously passes through the male shell wire end 1 and the male plug 13 is provided at the center of the side away from the male shell wire end 1 of the three male plugs 13. Three female housing wire grooves 7 are provided at the center of the side of the female housing wire end 6 away from the female end socket 10, which continuously pass through the female housing wire end 6 and the female end socket 10. The central axes of the male housing wire groove 17 and the female housing wire groove 7 are on the same straight line. The waterproof and breathable membrane 15 is located at the upper and lower ends of the junction of the male housing wire groove 17 and the female housing wire groove 7. Drain holes 8 are provided at the connection between the inner walls of both sides of the cavity 14 and the waterproof and breathable membrane 15. A direction indicator is provided near the connection between the female end socket 10 and the male housing wire end 1.
[0044] When the plastic shell is fixed, the protrusion 11 and the sealing groove 12 are connected by mortise and tenon, which ensures that water and dust will not enter the interior of the plastic shell from the connection when the plastic shell is connected. A layer of polyurethane coating is added to the outermost layer of the plastic shell material. Polyurethane has good wear resistance, elasticity and chemical corrosion resistance, and provides high mechanical strength. Brominated flame retardant is selected as the flame retardant layer 102 because brominated flame retardant has good thermal stability under high temperature conditions and can provide long-lasting flame retardant effect. Nylon is selected as the main material of the plastic shell because nylon has high strength and toughness and can withstand the mechanical stress generated during the plastic shell extraction process. Before transmitting data, fix the wire on the terminal, and then insert the terminal through the male shell wire groove 17 and the female shell wire groove 7 respectively. Inserted and fixed inside the plastic shell, the central axes of the female shell wire groove 7 and the male shell wire groove 17 are in the same straight line to ensure normal connection of the terminals. After the plastic shell is fixed, the terminal connection is located at the junction of the male shell wire groove 7 and the female shell wire groove 17. The heat generated when transmitting data between the terminals will dissipate outward from the junction of the male shell wire groove 7 and the female shell wire groove 17, dissipate to the cavity 14 through the waterproof breathable membrane 15, and finally be discharged from the air vent 5. External water may enter from the air vent 5 and accumulate in the cavity 14. A drainage hole 8 is opened between the cavity 14 and the waterproof breathable membrane 15 to allow the accumulated water in the cavity 14 to flow out. When connecting the plastic shell, align the direction marks on the female end socket 10 and the male shell wire end 1 to ensure correct connection of the terminals.
[0045] Working principle: Before using the plastic shell, first insert the wire with the terminal into the male shell wire groove 17 and the female shell wire groove 7, then insert the male end plug 13 into the female end socket 10, and at the same time, insert the lock tongue 2 on the male shell wire end 1 into the lock box 4 of the female end socket 10, and the lock block 3 on the lock tongue 2 extends from the lock hole 9 on the lock box 4. The support spring 16 under the lock tongue 2 ensures that the lock block 3 will not fall off from the lock hole 9, making the plastic shell more firmly fixed. The heat generated when the terminal connection in the plastic shell transmits data will be discharged from the air vent 5. At the same time, the waterproof and breathable membrane 15 ensures that the moisture entering from the air vent 5 will not affect the inside of the plastic shell. A protective layer 101 and a flame retardant layer 102 are added to the outside of the plastic shell. The protective layer 101 can reduce the wear of the plastic shell, and the flame retardant layer 102 can improve the safety performance of the plastic shell and avoid fire caused by short circuit.
[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
