[0001] The present application relates to the field of terminal blocks, and more particularly to a dust-proof housing and a terminal block. Background Art

[0002] Terminal blocks play a crucial role in electrical connections. To ensure the stability and safety of electrical connections, the dust-proof function becomes particularly important.

[0003] In the related art, a terminal block includes a body and a dust-proof housing. Among them, the dust-proof housing includes a housing body and a cover. Installation holes are formed on both sides of the housing body. The rotating shafts on both sides of the cover are respectively rotatably connected to the two installation holes. By rotating the cover, the housing body can be in an open state to facilitate the installation of the body into the housing body. At the same time, by rotating the cover, the housing body can be in a closed state to play a dust-proof role for the body.

[0004] Among them, the housing body is formed by injection molding with a mold, and a core-pulling structure is required to form the installation holes of the housing body. The mold structure with a core-pulling structure is complex and the production cost is high, resulting in a relatively high production cost of the housing body. Therefore, improvement is needed.

[0013] Preferably, clamping posts are provided on both sides of the cover body, and clamping grooves are provided on both sides of the top of the housing. Each of the clamping posts is clamped and limited in each of the clamping grooves.

[0014] By adopting the above technical solution, by providing the clamping posts and the clamping grooves, when each of the clamping posts is clamped and limited in each of the clamping grooves, the rotation of the cover body is restricted to ensure the dust-proof effect of the dust-proof housing.

[0015] Preferably, the perimeter of the clamping groove is smaller than the perimeter of the clamping post, and the perimeter of the clamping groove is greater than half of the perimeter of the clamping post.

[0018] By adopting the above technical solution, by providing the chamfers, it is convenient for the clamping post to be clamped and limited in the clamping groove.

[0019] Preferably, a plurality of limiting grooves are provided in the housing, and the bottom of the rotated cover body abuts against the groove side walls of each of the limiting grooves.

[0020] By adopting the above technical solution, by providing a plurality of limiting grooves, the rotated cover body is limited, thereby facilitating the installation of the main body.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above description of the drawings are intended to cover non-exclusive inclusion.

[0034] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] The following is combined with the attachedFigures 1-4 A further detailed description of the present application will be given.

[0036] An embodiment of the present application discloses a terminal block.

[0037] Referring to Figure 1 , the terminal block includes a plurality of bodies 1 and a dust-proof housing, and the plurality of bodies 1 are installed in the dust-proof housing.

[0038] Referring to Figure 1 and Figure 2 , specifically, the dust-proof housing includes a housing 2, the housing 2 is arranged in a rectangular frame shape, and outer grooves 21 are recessed on both outer side walls of the housing 2. The outer grooves 21 are arranged vertically and extend downward to the bottom of the housing 2, so that the outer grooves 21 communicate with the outside of the housing 2. At the same time, inner grooves 22 are recessed on both inner side walls of the housing 2. The inner grooves 22 are arranged vertically and are in the same straight line as the outer grooves 21. The upper ends of the inner grooves 22 extend to the top of the housing 2, so that the inner grooves 22 communicate with the outside of the housing 2. The two outer grooves 21 are respectively communicated with the two inner grooves 22, and mounting holes 23 are formed between the upper ends of the respective outer grooves 21 and the lower ends of the respective inner grooves 22.

[0039] During the production process of the housing 2, since the outer grooves 21 are arranged vertically and extend to the bottom of the housing 2, the lower die of the mold can directly form the outer grooves 21. Since the inner grooves 22 are arranged vertically and extend to the top of the housing 2, the upper die of the mold can directly form the inner grooves 22, and the mounting holes 23 are formed between the upper ends of the outer grooves 21 and the lower ends of the inner grooves 22. Thus, there is no need to use a core-pulling structure to process the mounting holes 23, which can effectively reduce the production cost of the mold, thereby reducing the production cost of the housing 2.

[0040] The dust-proof housing further includes a cover body 3. Two sides at one end of the cover body 3 protrude to form rotating shafts 31. The rotating shafts 31 are arranged in a cylindrical shaft shape. The two rotating shafts 31 are respectively inserted into the two mounting holes 23 to realize that the two rotating shafts 31 are respectively rotatably connected to the two mounting holes 23. The body 1 is inserted into the housing 2. By rotating the cover body 3, the cover body 3 is covered on the top of the housing 2, so that the housing 2 is in a closed state to play a dust-proof role for the body 1. At the same time, by rotating the cover body 3, the cover body 3 is separated from the top of the housing 2, so that the housing 2 is in an open state, facilitating the installation of the body 1 into the housing 2.

[0041] Referring to Figure 3, in some embodiments, reinforcing blocks 32 are formed protruding on both sides of the cover body 3. The reinforcing blocks 32 are arranged in the shape of rectangular blocks. One end of the rotating shaft 31 far from the mounting hole 23 is connected to both the reinforcing block 32 and the cover body 3 at the same time. Since the thickness of the cover body 3 is small, the reinforcing block 32 can thicken the connection part of the rotating shaft 31, so that the connecting area of the rotating shaft 31 is larger, thereby improving the connection strength of the rotating shaft 31 and thus improving the stability of the use of the rotating shaft 31.

[0042] Referring to Figure 1 and Figure 2 , in some embodiments, clamping posts 33 are also formed protruding on both sides of the cover body 3. The clamping posts 33 are cylinders. Correspondingly, clamping grooves 24 are formed sunken at the top of the housing 2. Rotate the cover body 3 to the horizontal state so that each clamping post 33 is respectively clamped and limited in each clamping groove 24 to realize the fixation of the cover body 3, thereby restricting the rotation of the cover body 3 and thus improving the stability of the cover body 3 covering the housing 2, and further ensuring the dust-proof effect of the dust-proof shell on the body 1.

[0043] In some embodiments, the perimeter of the clamping groove 24 is smaller than the perimeter of the clamping post 33, and the perimeter of the clamping groove 24 is larger than half of the perimeter of the clamping post 33. Press the clamping post 33 into the clamping groove 24 so that the clamping post 33 is more tightly clamped and limited in the clamping groove 24 to improve the clamping stability of the clamping post 33 and further ensure the dust-proof effect of the dust-proof shell on the body 1.

[0044] In some embodiments, chamfers 25 are provided on both sides of the housing 2 at the upper end of the clamping groove 24. When pressing the clamping post 33, the clamping post 33 contacts the chamfer 25 to facilitate the opening of the opening of the clamping groove 24, so as to facilitate clamping and limiting the clamping post 33 in the clamping groove 24.

[0045] Referring to Figure 2 and Figure 4 , in some embodiments, a plurality of limiting grooves 26 are formed in the housing 2. Disconnect each clamping post 33 from each clamping groove 24 and rotate the cover body 3 so that the cover body 3 rotates a certain angle, and the bottom of the cover body 3 abuts against the groove side wall of the limiting groove 26, so that the cover body 3 is limited in a plurality of limiting grooves 26, and the rotation of the cover body 3 under the action of gravity is avoided as much as possible, so as to facilitate the installation of the body 1 in the housing 2.

[0046] It should be noted that a guiding groove 27 is provided at the upper end of the inner groove 22 of the housing to facilitate the insertion of the rotating shaft 31 into the mounting hole 23.

[0047] The implementation principle of this embodiment is as follows: During the production process of the housing 2, since the outer groove 21 is vertically arranged and extends to the bottom of the housing 2, the lower die of the mold can directly form the outer groove 21. Since the inner groove 22 is vertically arranged and extends to the top of the housing 2, the upper die of the mold can directly form the inner groove 22, and an installation hole 23 is formed between the upper end of the outer groove 21 and the lower end of the inner groove 22. In this way, there is no need to use a core-pulling structure to process the installation hole 23, which can effectively reduce the production cost of the mold, thereby reducing the production cost of the housing 2.

[0048] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
