[0021] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1 to 7 The utility model provides a technical solution: a distribution box with an anti-interference structure, including an outer top cover 1, the four corners of the bottom of the outer top cover 1 are snap-connected to the top of the inner top cover 2, the bottom of the inner top cover 2 is plugged into the inner wall of the box body 3, the bottom wall of the inner wall of the box body 3 is provided with a metal partition 4, the top of the metal partition 4 is provided with a metal baffle 5, the bottom of the box body 3 is provided with a plurality of through holes 6, the four corners of the bottom of the box body 3 are provided with a mounting base 7, the inside of the mounting base 7 is fixedly installed with a shock-absorbing spring 8, and a heat dissipation hole 9 is opened on the outer wall of one side of the box body 3.
[0023] In this embodiment, Figure 1 and Figure 3 As shown, a metal mesh is provided in the middle layer between the outer top cover 1 and the inner top cover 2; it should be noted that, because a metal mesh is provided between the outer top cover 1 and the inner top cover 2, the material of the metal mesh is conductive metal, when other electronic components in the power distribution box are started to work, an electric field will be formed between different electronic components, and the metal mesh provided between the outer top cover 1 and the inner top cover 2 can destroy the electric field formed by the electronic components through the short-circuit effect of the conductive metal, thereby effectively resisting interference.
[0024] In this embodiment, Figure 3 , Figure 5 and Figure 7As shown, four protrusions 101 are provided at the four corners of the bottom of the outer top cover 1, and four grooves 201 corresponding to the protrusions 101 are provided at the four corners of the top of the inner top cover 2; it should be noted that the lengths of the four protrusions 101 provided at the four corners of the bottom of the outer top cover 1 are consistent with the grooves 201 provided at the four corners of the top of the inner top cover 2, so the protrusions 101 can be fully inserted into the corresponding grooves 201 and tightly engaged with them, so that the outer top cover 1 and the inner top cover 2 are combined into a whole, and the metal mesh provided between the outer top cover 1 and the inner top cover 2 will be firmly fixed between the two top covers without falling off, and after a period of use, the internal metal mesh can also be replaced by disassembling the outer top cover 1 and the inner top cover 2.
[0025] In this embodiment, Figure 3 and Figure 4 As shown, the metal partition 4 is composed of several detachable plug-ins; it should be noted that before the outer top cover 1 and the inner top cover 2 are combined into a whole and completely closed with the box body 3, a metal partition 4 will be provided on the bottom wall of the inner wall of the box body 3. The material of the metal partition 4 is lead plate, because there will be multiple groups of different electrical components inside the automobile distribution box, and when these electrical components are started and connected, these electronic devices are gathered together, and electromagnetic interference will be generated between them, thereby affecting the use of the entire distribution box. Therefore, a metal partition 4 is needed to separate them, and the metal partition 4 is composed of several detachable plug-ins. Therefore, the composition position of the plug-ins can be determined according to the placement and size of different electronic components, so that all electronic components can be well separated, and the metal partition 4 and the metal baffle 5 on its top can be combined into several complete shielding spaces, which effectively prevents electromagnetic interference between the various electronic components.
[0026] In this embodiment, Figure 2 , Figure 3 and Figure 5 As shown in the figure, a sealing rubber ring is provided between the metal baffle 5 and the metal partition 4; it should be noted that when the metal baffle 4 is used to combine into a metal baffle 4 of a fixed shape according to the size and placement of different electronic components, the four sides of the electronic components are completely separated from each other. At this time, it is only necessary to completely cover the metal baffle 5 on the top of the metal baffle 4 to form a number of complete shielding spaces, and a layer of sealing rubber ring is also bonded between the metal baffle 4 and the metal baffle 5, which can not only connect the metal baffle 4 and the metal baffle 5 as a whole, but also effectively prevent different electromagnetic fields from being affected by the gap between the two.
[0027] In this embodiment, Figure 5 and Figure 6As shown, a layer of dustproof net 901 is fixedly connected to the connection between the heat dissipation hole 9 and the box body 3; it should be noted that when the electronic components in the automobile distribution box are started and connected to the corresponding parts of the automobile, a large amount of heat will be generated, and overheating of the equipment will also affect or damage the use of the entire device. Therefore, it is necessary to provide heat dissipation holes 9 inside the box body 3 to reduce heat accumulation during the use of the equipment, and a layer of dustproof net 901 is also fixedly connected at the connection between the heat dissipation hole 9 and the box body 3 to prevent external dust from entering the equipment through the heat dissipation hole 9 during daily use, thereby damaging some internal electronic components, thereby affecting the use of the entire equipment and reducing the service life of the equipment.
[0028] The use method and advantages of the utility model: When the distribution box with anti-interference structure is used, the working process is as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, firstly, the metal mesh is placed in the middle layer between the outer top cover 1 and the inner top cover 2, and then the four protrusions 101 provided at the four corners of the bottom of the outer top cover 1 are completely inserted into the corresponding grooves 201 provided at the four corners of the top of the inner top cover 2, so that the protrusions 101 at the corresponding positions are tightly engaged with the grooves 201, so that the outer top cover 1 and the inner top cover 2 are combined into a whole, and the metal mesh provided between the outer top cover 1 and the inner top cover 2 will be firmly fixed between the two top covers without falling off, and after using for a period of time, the outer top cover can also be 1 and the inner top cover 2 are disassembled to replace the internal metal mesh. Because the material of the metal mesh is conductive metal, when other electronic components in the power distribution box are started to work, an electric field will be formed between different electronic components, and the metal mesh can destroy the electric field formed by the electronic components through the short-circuit effect of the conductive metal, thereby effectively resisting interference. Before the outer top cover 1, the inner top cover 2 and the box body 3 are closed, because there are multiple groups of different electrical components inside the automobile power distribution box, and these electronic devices are gathered together, electromagnetic interference will be generated between each other, thus affecting the entire distribution box. The use of the electrical box, therefore, a metal partition 4 is provided on the bottom wall of the inner wall of the box body 3. The material of the metal partition 4 is lead plate, which can separate various electronic components, and the metal partition 4 can determine the composition position of the plug board according to the placement and size of different electronic components, so that all electronic components can be well separated. At the same time, a metal baffle 5 is also provided on the top of the metal partition 4, and a layer of sealing rubber ring is also bonded between the metal partition 4 and the metal baffle 5. The sealing rubber ring can not only connect the metal partition 4 and the metal baffle 5 as a whole, but also effectively prevent the gap between the two from affecting different electromagnetic fields, so that the metal partition 4 and the metal baffle 5 on the top are combined into several complete shielding spaces, which effectively prevents the electronic components placed in each shielding space from electromagnetic interference, and the through hole 6 provided at the bottom of the box body 3 allows the connecting wire to pass through it and connect to the automobile equipment, so as not to destroy the shielding space. The assembled automobile distribution box is firmly installed on the automobile through the mounting base 7 at the bottom of the box body 3.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments.
