Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of power fittings technology, and more specifically, to a wear-resistant power fitting. Background Technology
[0002] Power fittings are metal components used in power systems to connect, secure, and protect conductors and cables, as well as support electrical equipment. They are widely used in transmission and distribution lines, substations, and other applications to ensure the safe and stable operation of power systems.
[0003] Traditional power fittings have the following shortcomings: A portion of traditional power fittings consists of power fitting clamps used to secure wires. Currently, most clamps on the market are based on a fixed arc groove design. While this design can accommodate various cable sizes and eliminates the need for frequent tool changes, in harsh weather conditions such as rainwater penetration or snow cover, if there are tiny gaps between the clamp and the wire, rainwater may penetrate and accelerate material aging. After the rainwater seeps in, it freezes and expands, causing bulging or even cracking, and also leading to corrosion of the steel core. Therefore, improvements are needed. Utility Model Content

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] like Figures 1-8As shown, a wear-resistant electrical fitting according to an embodiment of the present disclosure is illustrated, including a clamp 1, a clamp 2 below the clamp 1, a clamping groove 6 at the bottom of the clamp 1, a clamping groove 5 at the top of the clamp 2, a semi-annular groove 17 at the front end of both the clamp 1 and the clamp 2, a movable groove 18 at the bottom of the semi-annular groove 17, slots 19 evenly distributed on the inner side of the movable groove 18, a connecting plate 22 movably installed inside the semi-annular groove 17, and locking blocks 24 fixedly installed on the outer sides of both ends of the connecting plate 22, the locking blocks 24 corresponding to the slots 19, and a baffle 23 fixedly installed on the outer side of the connecting plate 22, the baffle 23 extending to the outer side of the clamp 1.
[0034] In some examples, when securing the wire, the wire is first placed inside the clamping groove 5, then clamp 1 is covered, and clamp 1 and clamp 2 are secured by inserting bolts into the round hole 4. Then, push rod 7 is pressed down to secure the wire, clamp 1 is released to allow it to remain stationary in its natural state, baffle 23 is pressed inward to move it into the semi-annular groove 17, thereby disengaging the locking block 24 from the slot 19. Then, baffle 23 is rotated above clamp 1 in its natural state, and locking block 24 is inserted into the slot 19 to secure it, thus blocking rainwater through baffle 23.
[0035] By adjusting the position of the baffle 23 when the clamp 1 is stationary, it is positioned above the clamp 1, thereby shielding the clamping slots 5 and 6. Compared with traditional power fittings, this wear-resistant power fitting uses the baffle 23 to shield rainwater, preventing rainwater from entering the gap between the clamping slots 5 and 6 and the wire, thus effectively reducing rainwater penetration, improving the service life of the clamps 1 and 2, and enhancing its overall practicality.
[0036] like Figures 1-8 As shown, a wear-resistant power fitting according to another embodiment of the present disclosure is illustrated. A clamping block 8 is movably installed inside the clamping groove 2 6. A push rod 7 penetrating the clamp 1 is fixedly installed above the clamping block 8. A bottom ring block 9 located outside the push rod 7 is fixedly installed above the clamp 1. An elastic connecting block 10 is fixedly installed above the bottom ring block 9. An elastic ring 11 is fixedly installed above the elastic connecting block 10. An outer ring block 12 is fixedly installed outside the bottom ring block 9. A threaded ring 14 is movably installed inside the outer ring block 12. A retaining ring 15 is fixedly installed below the threaded ring 14.
[0037] In some examples, after the wire is fixed by the clamping block 8, the knob 16 is rotated, causing the knob 16 to drive the threaded ring 14 to rotate. The threaded ring 14 rotates and moves downward inside the threaded groove 13, thereby causing the retaining ring 15 to rotate and move downward. At this time, the retaining ring 15 squeezes the inclined surface of the elastic ring 11, causing the elastic ring 11 to deform. The elastic ring 11 contracts inward to fix the push rod 7, and at the same time, it also blocks the gap at the connection between the push rod 7 and the clamp 1.
[0038] By rotating the knob 16, the elastic ring 11 contracts inward to fix the push rod 7, and at the same time, it covers the gap at the connection between the push rod 7 and the clamp 1. Compared with traditional power fittings, this wear-resistant power fitting can fix the push rod 7 by rotating the knob 16, which is convenient for fixing the wire through the push rod 7. At the same time, it can effectively prevent rainwater penetration and improve the service life of the push rod 7.
[0039] like Figures 1-8 As shown, a wear-resistant electrical fitting is provided in another embodiment of the present disclosure, wherein a push plate 20 located at the bottom of a connecting plate 22 is movably mounted inside a movable groove 18, and a telescopic spring 21 is elastically mounted between the inner side of the push plate 20 and the inner side of the movable groove 18.
[0040] In some examples, when the baffle 23 is pressed inward, the push plate 20 is subjected to a squeezing force and moves inward to squeeze the telescopic spring 21, causing the telescopic spring 21 to deform. The telescopic spring 21 releases its elastic potential energy to assist in the installation of the locking block 24.
[0041] like Figures 1-8 As shown, it illustrates a wear-resistant power fitting in another embodiment of the present disclosure, wherein mounting plates 3 are fixedly installed on both sides of clamp 1 and clamp 2, and the surface of the mounting plates 3 is provided with round holes 4.
[0042] In some examples, the mounting plates 3 are secured by stacking clamp 1 and clamp 2 together and then inserting bolts into the round hole 4.
[0043] like Figures 1-8 As shown, it illustrates a wear-resistant electrical fitting in another embodiment of the present disclosure, wherein a threaded groove 13 is provided on the inner side of the top end of the outer ring block 12, and the threaded groove 13 corresponds to the threaded ring 14.
[0044] In some examples, the threaded ring 14 rotates inside the threaded groove 13, thereby causing the threaded ring 14 to move up and down inside the threaded groove 13.
[0045] like Figures 1-8As shown, a wear-resistant electrical fitting is provided in another embodiment of the present disclosure, wherein a knob 16 is fixedly mounted above a threaded ring 14, and the knob 16 is located above an outer ring block 12.
[0046] In some examples, rotating the knob 16 causes the threaded ring 14 to rotate inside the threaded groove 13, thereby causing the retaining ring 15 to move up and down around the outer side of the elastic ring 11.
[0047] like Figures 1-8 As shown, it illustrates a wear-resistant electrical fitting in another embodiment of the present disclosure, having a total of six slots 19, with each pair of adjacent slots 19 corresponding to a block 24.
[0048] In some examples, the connecting plate 22 is secured by mounting the card block 24 inside the card slot 19, thereby allowing the baffle 23 to block rainwater.
[0049] like Figures 1-8 As shown, it illustrates a wear-resistant electrical fitting in another embodiment of the present disclosure, wherein the cross-section of the elastic ring 11 is a right trapezoid, the cross-section of the retaining ring 15 is an inverted right triangle, and the inclined surface of the elastic ring 11 corresponds to the inner side of the retaining ring 15.
[0050] In some examples, the inclined surface of the retaining ring 15 presses against the inclined surface of the elastic ring 11, causing the elastic ring 11 to contract inward and fix the push rod 7.
[0051] like Figures 1-8 As shown, it illustrates a wear-resistant power fitting in another embodiment of the present disclosure, wherein the arc surface of the clamping block 8 corresponds to the arc surface of the clamping groove 5, and there are two clamping grooves 5 in total.
[0052] In some examples, two clamping slots (5) are provided to facilitate the fixing of two wires and make them easier to use.
[0053] like Figures 1-8 As shown, it illustrates a wear-resistant electrical fitting in another embodiment of the present disclosure, wherein the width of the semi-annular groove 17 corresponds to the baffle 23, and the baffle 23 corresponds to the connecting plate 22.
[0054] In some examples, the position of the locking block 24 is adjusted by pressing the baffle 23 inward, causing it to move into the interior of the semi-annular groove 17.
[0055] Working principle and usage process of this utility model:
[0056] When fixing the wire, first place the wire inside the clamping groove 5, then cover the clamp 1, and fix the clamp 1 and clamp 2 by inserting the bolt into the round hole 4. Then press down the push rod 7 to fix the wire. Then release the clamp 1 and let it rest in its natural state. Then press the baffle 23 inward to move the baffle 23 into the semi-annular groove 17, so that the locking block 24 is disengaged from the slot 19. Then rotate the baffle 23 above the clamp 1 in its natural state, and then insert the locking block 24 into the slot 19 to fix it, thereby blocking rainwater through the baffle 23.
[0057] After the wire is fixed by the clamping block 8, rotate the knob 16 to make the knob 16 drive the threaded ring 14 to rotate. The threaded ring 14 rotates and moves downward inside the threaded groove 13, thereby causing the retaining ring 15 to rotate and move downward. At this time, the retaining ring 15 squeezes the inclined surface of the elastic ring 11, causing the elastic ring 11 to deform. The elastic ring 11 contracts inward to fix the push rod 7, and at the same time, it also blocks the gap at the connection between the push rod 7 and the clamp 1.
