Description

Technical Field

[0001] The invention belongs to the technical field of electric protection devices, and in particular relates to a surge protector. Background Art

[0002] Surge protector, also called lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other equipment in the circuit. It is currently widely used in the fields of power, communication, data, industry, medical treatment, transportation, etc.

[0003] The surge protector includes a protector body and a base. When in use, the protector body needs to be installed on the base, and then the base is electrically connected to the device. In actual use, once the protector body is installed on the base, it is difficult to manually unplug it. Specific tools are required to disassemble the protector body, which is not convenient for repair and inspection of the protector body. In addition, since the protector body lacks a corresponding fixing structure in the plug-in and unplug direction, when impacted by external force, the protector body and the base are still prone to looseness. Since the direction of the external force and the plug-in and unplug direction are not completely consistent, the installation structure between the protector body and the base may also be damaged. Summary of the invention

[0004] The existing surge protector is not easy to remove directly from the base, and when subjected to external force, the protector body and the base are prone to looseness, affecting normal use. To solve the above problems, the following invention is proposed:

[0005] A surge protector comprises a protector body and a base, wherein the base is provided with a mounting groove for inserting the protector body, a prying plate extending horizontally is respectively provided on both sides of the protector body, a rotating plate is movably installed on both sides of the base, and the rotating plate is provided with a prying groove located below the prying plate. After the protector body is inserted into the mounting groove, the prying groove is pressed downward by the prying plate to drive the rotating plate to rotate. After the rotating plate rotates, the prying groove is engaged with the upper part of the prying plate to prevent the protector body from moving vertically upward. After the rotating plate rotates downward, the prying groove contacts the prying plate upward to drive the protector body to leave the mounting groove.

[0006] Furthermore, a guiding inclined surface extending obliquely upward is provided at the bottom of the pry plate. When the protector body is inserted into and removed from the mounting groove, the guiding inclined surface conflicts with the pry groove, thereby improving the efficiency of inserting the protector body into the mounting groove.

[0007] Furthermore, a sliding plate is provided on the rotating plate, and engaging grooves are provided on both sides of the protector body. After the sliding plate moves and fits into the engaging groove, the rotating plate is prevented from rotating, thereby improving the stability of the rotating plate.

[0008] Furthermore, the rotating plate is provided with a slide groove, the sliding plate includes a push plate and a clamping plate, the push plate is provided with a slider and a slot, the slider is movably inserted into the slide groove, and the clamping plate is provided with a plug column that is inserted into the slot.

[0009] Furthermore, a pushing portion is provided on the push plate, and a plurality of spaced protrusion structures are provided on the pushing portion; a pad is also provided on the base, and after the rotating plate rotates until the protector body is separated from the mounting groove, the pad contacts the rotating plate.

[0010] Furthermore, a first combination groove and a first combination plate matching the first combination groove are respectively provided on both sides of the base, a limiting groove is provided on the inner side of the first combination groove, and a limiting block is provided on the outer side of the first combination plate. After the first combination plate matches the first combination groove, the limiting block is inserted into the limiting groove to realize the mutual combination of multiple bases.

[0011] Furthermore, a second combination groove perpendicular to the first combination groove and a second combination plate perpendicular to the first combination plate are respectively provided on both sides of the protector body. The second combination groove cooperates with the second combination plate to realize the mutual combination of multiple protector bodies, and constitutes a restraining relationship with the combination on the base to prevent the protector body or the base from being separated from each other due to force.

[0012] Furthermore, the base includes a front seat cover and a rear seat cover, both of which are provided with axle seats, and connecting shafts are provided on both sides of the rotating plate, and the connecting shafts are movably inserted into the axle seats to rotatably install the rotating plate on the base.

[0013] The present invention proposes a surge protector, which has the beneficial effect that, by arranging pry plates on both sides of the protector body, rotating plates on both sides of the base, and pry grooves on the rotating plates, after the protector body is installed on the base, the pry plates press the rotating plates downward, and the rotating plates drive the pry grooves to rotate, and the rotated pry grooves are blocked above the pry plates to prevent the protector body from being separated from the base, thereby improving the stability of the installation of the protector body; after the rotating plate is rotated downward, the pry grooves rotate downward and resist the pry plates upward until the protector body moves upward to partially separate from the base, at which time the protector body can be quickly removed from the base, which is more convenient and efficient.

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with embodiments.

[0022] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of protection of this application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0024] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0025] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0026] like Figure 1-Figure 3 As shown, it is a preferred embodiment of the present invention, a surge protector, including a protector body 1 and a base 2, the protector body 1 is provided with guide grooves 18 located on both sides and contact pins extending from the bottom, the base 2 is provided with a mounting groove 21, the mounting groove 21 is provided with a guide block 25 and a contact pin socket matching the guide groove 18, the protector body 1 is inserted into the mounting groove 21 through the guide groove 18, and the contact pin is inserted into the contact pin socket to electrically connect the protector body 1 and the base 2.

[0027] A horizontally extending pry plate 11 is provided on both sides of the protector body 1, and a guide slope 12 extending obliquely upward is provided at the bottom of the pry plate 11. A movable rotating plate 3 and a pad 26 are provided on both sides of the base 2. The rotating plate 3 is located on the side of the pry plate 11 and one side of the rotating plate 3 is provided with a pry groove 32 located below the pry plate 11, and the other side is always located above the pad 26.

[0028] When the protector body 1 is not inserted into the installation groove 21, the rotating plate 3 is horizontally arranged and contacts the pad 26, and the opening of the prying groove 32 extends vertically upward. In the process of inserting the protector body 1 downward into the installation groove 21, the protector body 1 is first partially inserted into the installation groove 21 through the guide block 25, and then the protector body 1 is continued to be moved, and the guide slope 12 partially contacts the prying groove 32. The prying groove 32 rotates downward after being pressed, and the rotating plate 3 rotates upward as a whole until the protector body 1 is completely inserted into the installation groove 21. At this time, the rotating plate 3 rotates to a vertical state, and the prying groove 32 becomes a cover on the prying plate 11, when it is pulled upward, it will be blocked by the cover and cannot move, thereby improving the stability and reliability of the connection between the protector body 1 and the base 2 when the protector body 1 or the base 2 is subjected to external force; when the protector body 1 needs to be removed from the base 2, the rotating plate 3 is rotated to both sides, and after rotation, the rotating plate 3 upwardly contacts the guide inclined surface 12 of the pry plate 11 through the pry groove 32, and the two sides of the protector body 1 are pressed and move upward and disengage from the mounting groove 21. When the rotating plate 3 is rotated to contact with the pad 26, the protector body 1 is released from the mounting groove 21. At this time, the protector body 1 can be easily pulled out of the mounting groove 21.

[0029] Specifically, the base 2 also includes a front seat cover 5 and a rear seat cover 6, each of which is provided with an axle seat 22, and connecting shafts 31 are provided on both sides of the rotating plate 3. After the front seat cover 5 and the rear seat cover 6 are horizontally combined, the connecting shaft 31 is movably inserted into the axle seat 22 to rotatably install the rotating plate 3 on the base 2.

[0030] Furthermore, if Figure 4 and Figure 5 As shown, a sliding plate 4 is also provided on the rotating plate 3, and a snap-fitting groove 13 with an opening facing each other is respectively provided on both sides of the protector body 1. The shape of the snap-fitting groove 13 matches one end of the sliding plate 4. After the protector body 1 is fully inserted into the mounting groove 21, the sliding plate 4 rotates to a vertical state with the rotation of the rotating plate 3. At this time, the bottom of the sliding plate 4 is just located directly above the opening of the snap-fitting groove 13. After the sliding plate 4 slides downward, its bottom is inserted into the snap-fitting groove 13 to prevent the rotating plate 3 from rotating, thereby further improving the stability of the installation of the protector body 1.

[0031] Specifically, the sliding plate 4 includes a push plate 42 and a locking plate 41. A sliding groove 33 is provided on the rotating plate 3. A slider 43 is provided on one side of the push plate 42, and a pushing portion 46 is provided on the other side. The slider 43 is movably inserted into the sliding groove 33. A plurality of spaced protrusions are provided on the pushing portion 46. A slot 44 is also provided on the slider 43. A plug 45 is provided on the locking plate 41 to be inserted into the slot 44 to fix the locking plate 41 and the push plate 42. After pushing the pushing portion 46, the push plate 42 drives the locking plate 41 to move relative to the rotating plate 3. After the locking plate 41 moves, it is inserted into or out of the locking groove 13. It should be particularly noted that the locking groove 13 is spaced apart from the pry plate 11, and the pry plate 11 extends horizontally outward for a longer distance to prevent the locking groove 13 from hindering the cooperation between the pry groove 32 and the pry plate 11.

[0032] In actual use, it is often necessary to combine multiple surge protectors together. Currently, most of them are implemented by a plate-like structure that is snapped onto the bottom of the base 2, rather than combining the surge protectors themselves, which has poor stability. Figure 1-Figure 3As shown, first combination grooves 14 and first combination plates 15 are respectively vertically provided on both sides of the base 2, the first combination plates 15 and the first combination grooves 14 match each other, a limiting groove 16 is provided on the inner side of the first combination groove 14, and a limiting block 17 is provided on the outer side of the first combination plate 15. When the bases 2 of two different surge protectors need to be matched, the first combination plate 15 on one base 2 is downwardly matched and inserted into the first combination groove 14, and the limiting block 17 is also matched and inserted into the limiting groove 16 to combine and connect the bases 2, and the bases 2 can only be separated by vertical movement, thereby improving the stability of the combined surge protector.

[0033] Furthermore, second combination slots 23 and second combination plates 24 are horizontally provided on both sides of the protector body 1, and the second combination plate 24 can be directly moved horizontally to be inserted into the second combination slot 23. After multiple surge protectors that need to be used in combination are combined with each other on the base 2, their protector bodies 1 are combined with each other in this way and are inserted into the corresponding bases 2 in sequence. The protector bodies 1 are blocked by the limit blocks 17 and the limit slots 16 and cannot move in the horizontal direction, and the base 2 is blocked by the second combination slots 23 and the second combination plates 24 and cannot be separated from each other at any angle. To release the combined state between the surge protectors, the protector body 1 must be unplugged from the base 2 first, and the unplugging of the protector body 1 is blocked by the prying slot 32 and cannot be carried out. Compared with the existing surge protectors, the present invention has higher stability when used in combination.

[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
