The grooves 201 are provided with wiring terminals 210, and the openings of the grooves 201 are provided with protective covers 120 that can be opened and closed and are used to protect the wiring terminals 210. The wiring shell 200 is provided with a detachable installation component 130 for installing the filter body 100.

[0026] In this embodiment, the filter body 100 has a housing, and a filter circuit composed of a capacitor, an inductor, and a resistor is arranged in the housing, which are all existing structures and are not described in detail here; wherein, the wiring components 110 at both ends of the filter body 100 form an input end and an output end, and can be used to better connect with the connecting wire, so that the filter is connected between the power supply and the load device to process the power supply signal of the load device;

[0027] In actual use, the lower side of the filter body 100 protrudes outward at both ends to form a mounting plate 101. By setting the mounting plate 101, the filter body 100 can be better fixed on the mounting surface, wherein the mounting surface can be a load device, that is, the filter can be installed on the load device through the mounting plate 101.

[0028] The terminal housing 200 can be made of plastic injection molding, and is fixed to the filter body 100 by bonding. A groove 201 for installing the terminal 210 is provided thereon. The terminal 210 adopts a commonly used model in the prior art, and the specific model is not limited again. They are all connected to the filter circuit in the filter body 100.

[0029] Combination Figure 2 As shown, the groove 201 in this embodiment has openings on both sides, one opening is arranged in a direction away from the filter body 100, and the other opening is arranged above the filter body 100; wherein, by the arrangement of the protective cover 120, the protective cover 120 can block the upper opening of the groove 201, that is, the protective cover 120 can protect the terminal block 210 in the groove 201 at the upper opening of the groove 201, and the upper opening of the groove 201 can be opened by rotating the protective cover 120 upward, so that it is convenient to screw the screws on the terminal block 210 to fix the connecting wire to the terminal block 210. By utilizing the above structure, the protective cover 120 can protect the terminal block 210 and the connecting wire connected to the terminal block 210 at the upper opening of the groove 201 to avoid the influence of the external environment, thereby effectively extending the service life of the filter.

[0030] Combination Figure 3 As shown, in this embodiment, a step groove 202 is provided on the side wall opposite to the groove 201 and at the upper opening; the protective cover 120 includes a horizontal plate portion 310 overlapped on the step groove 202 for covering the upper opening of the groove 201 and a vertical plate portion 320 blocking the outer opening of the groove 201, and the groove 201 is provided with a mounting shaft 203 passing through the horizontal plate portion 310 and located at the innermost end of the groove 201, and a fixed shaft 204 located at the lower end of the mounting shaft 203, and an elastic rope (not shown in the figure) is provided between the fixed shaft 204 and the corresponding horizontal plate portion 310, and the elastic rope is used to pull the protective cover 120 to overlap the step groove 202.

[0031] In this embodiment, the protective cover 120 is L-shaped, and has a horizontal plate portion 310 and a vertical plate portion 320. When the horizontal plate portion 310 is overlapped on the step groove 202, the protective cover 120 can be preferably arranged at the upper opening of the groove 201, that is, the wiring terminal 210 therein is protected at the upper opening. At this time, the vertical plate portion 320 is located at the front opening of the groove 201, and is used to protect the inside of the groove 201 at the front opening of the groove 201, that is, the protective effect of the protective cover 120 is better.

[0032] Among them, by installing the shaft 203 through the horizontal plate portion 310 and being located at the innermost end of the groove 201, the rotation connection of the protective cover 120 in the corresponding groove 201 is preferably realized, so that the protective cover 120 can rotate, so that it can rotate upward at the upper opening of the groove 201 to open and close the upper opening of the groove 201;

[0033] Among them, by setting the fixed shaft 204 and the elastic rope, in a natural state, the elastic rope can be used to pull the horizontal plate portion 310 to always overlap the step groove 202, so that the protective cover 120 always blocks and protects the upper opening of the groove 201. By utilizing the elastic force of the elastic rope, after the protective cover 120 is rotated upward and opened under the action of external force, after the external force is removed, the elastic rope can reset and drive the protective cover 120 to automatically reset and overlap the step groove 202, so that it automatically protects the inside of the groove 201, which is convenient for use.

[0034] Combination Figure 4 As shown, in this embodiment, the mounting component 130 includes a baffle 410 disposed at the outer opening of the groove 201, and both sides of the baffle 410 are bent to form a first mounting portion 411 that cooperates with the side wall of the wiring shell 200. A movable fixing plate 420 is provided on the baffle 410, and the lower end of the fixing plate 420 is bent to form a second mounting portion 421.

[0035] In this embodiment, the baffle 410 can shield the front opening of the groove 201, so that it can shield and protect the groove 201 at the front side of the groove 201, that is, prevent the external environment from affecting the wiring terminal 210 and the connecting wire fixedly connected to the wiring terminal 210 through the front opening of the groove 201, so that it is better protected. When it is actually used, a gap is formed between the vertical plate portion 320 and the baffle 410 for the connecting wire to extend into the groove 201, wherein the two sides of the baffle 410 are bent to form a first mounting portion 411, and the baffle 410 can be preferably mounted on the corresponding side wall of the wiring shell 200 by screws, that is, the installation of the baffle 410 on the wiring shell 200 is realized;

[0036] Among them, through the arrangement of the fixing plate 420 and the second mounting portion 421, the second mounting portion 421 can be fixed on the mounting surface by bolts, so that the fixing plate 420 is fixedly connected to the mounting surface, so that after the filter body 100 is fixed on the mounting surface by the mounting plate 101, it can be further fixed on the mounting surface by the mounting component 130, so that the installation of the filter on the mounting surface is more stable.

[0037] In this embodiment, the fixed plate 420 is provided with a slide groove 422 parallel to its moving direction, and the baffle 410 is provided with a threaded column 412 penetrating the corresponding slide groove 422, and the threaded column 412 is threadedly connected with a nut 413 for fixing the fixed plate 420 to the baffle 410.

[0038] Through the structure in this embodiment, the fixation between the fixing plate 420 and the baffle 410 can be released by loosening the nut 413, so that the fixing plate 420 can move along the baffle 410, thereby effectively adjusting the position of the second mounting portion 421, that is, adjusting the support height of the mounting component 130, so that the filter can be installed on different mounting surfaces, thereby improving the applicability of the filter.

[0039] In this embodiment, the second mounting portion 421 protrudes outward to form a positioning portion 423 that matches with the lower side surface of the baffle 410 .

[0040] By setting the positioning portion 423 in this embodiment, the positioning portion 423 can abut against the lower end surface of the baffle 410, preferably improving the matching strength between the baffle 410 and the fixing plate 420 when abutting, so that the filter can be installed better.

[0041] Working principle: First, install the filter body 100 on the load device through the mounting plate 101, then connect the mounting component 130 to the corresponding wiring shell 200 through the first mounting portion 411, and then adjust the position of the fixing plate 420 by screwing the nut 413 so that the second mounting portion 421 thereon fits with the load device, and fix it to the load device by bolts, so that the installation of the filter on the load device is more stable, and then rotate the protective cover 120 upwards, and fix the connecting wire to the terminal 210 by screwing the screw on the terminal 210, so that the filter is better connected between the power supply and the load device, and better enables it to process the power signal of the load device.
