[0029] like Figures 1 to 6As shown, a grounding terminal comprises a terminal body 1, on which a connection hole 11 is provided; at least one side of the terminal body 1 is provided with a first protruding structure 21, and the end of the first protruding structure 21 away from the terminal body 1 is provided with a sharp portion 211 that can pierce the surface insulation layer of the electrical device.
[0030] When wiring, it is only necessary to connect the grounding terminal to the electrical device with a connector and press the grounding terminal. The first protruding structure 21 of the grounding terminal can prevent the grounding terminal and the electrical device from loosening, and the sharp portion 211 on the first protruding structure 21 can pierce the insulating layer on the surface of the electrical device, so that the grounding terminal is directly connected to the conductive part of the electrical device to achieve "grounding". Using the grounding terminal in the utility model for grounding is conducive to reducing the parts used for grounding, simplifying the grounding operation, and improving work efficiency.
[0031] In some specific embodiments, reference Figure 1 , first protrusion structures 21 are provided on both sides of the terminal body 1.
[0032] Both sides of the terminal body 1 are provided with a first protrusion structure 21. When performing the grounding operation, there is no need to distinguish the front and back sides of the grounding terminal. Regardless of the front and back sides, there are corresponding sharp portions 211 that can pierce the insulating layer on the surface of the electrical device, which is conducive to further simplifying the grounding operation and further improving the grounding efficiency.
[0033] In addition, a first protruding structure 21 is provided on both sides of the terminal body 1, so that the grounding terminal can not only pierce the insulating layer on the surface of the electrical device through the sharp portion 211, but the first protruding structure 21 on the other side of the grounding terminal can also contact the connecting piece used to tighten the grounding terminal, thereby increasing the friction between the connecting piece and the grounding terminal, preventing the connecting piece and the grounding terminal from loosening, and improving the wiring quality.
[0034] In some other embodiments, the first protruding structure 21 is disposed on only one side of the terminal body 1 , and when grounded, the first protruding structure 21 on the terminal body 1 faces the surface of the electrical device.
[0035] In some other embodiments, a first protrusion structure 21 is provided on one side of the terminal body 1, and a second protrusion structure is provided on the other side. The second protrusion structure is different from the first protrusion structure 21 in that: the second protrusion structure is not provided with a sharp portion 211 that can pierce the insulating layer on the surface of the electrical device, and the second protrusion structure is only used to increase the friction between the connector and the grounding terminal. When grounding, the first protrusion structure 21 of the terminal body 1 faces the surface of the electrical device, and the second protrusion structure faces the connector.
[0036] In some specific embodiments, reference Figure 1A tooth plate 2 is provided on the peripheral side of the terminal body 1, and both ends of the tooth plate 2 protrude from both sides of the terminal body 1 respectively. The portion of the tooth plate 2 protruding from the terminal body 1 is called a first protruding structure 21, and both ends of the tooth plate 2 are provided with sharp portions 211.
[0037] The tooth plate 2 protrudes from the terminal body 1 to form "teeth" for increasing the friction between the electrical device and the connector in contact with the ground terminal, and can pierce the insulating layer on the surface of the electrical device.
[0038] In some other embodiments, the first protrusion structure 21 may be directly disposed on the side of the terminal body 1 , such as a welding metal protrusion, and the end of the metal protrusion away from the terminal body 1 is a pointed end.
[0039] In some specific embodiments, reference Figure 1 The tooth plate 2 is relatively inclined to the terminal body 1 , and the sharp portion 211 includes an edge or vertex on the tooth plate 2 away from the terminal body 1 .
[0040] The tooth plate 2 is inclined to the terminal body 1, forming "teeth" similar to the saw teeth on a serrated gasket. Since the tooth plate 2 is inclined to the terminal body 1, when the connector presses the grounding terminal against the surface of the electrical device, the edge or vertex on the tooth plate 2 away from the grounding terminal will first contact the electrical device. The edges and vertices on the tooth plate 2 are relatively sharp parts, which are conducive to effectively piercing the insulating layer on the surface of the electrical device. Moreover, in the process of the connector pressing the grounding terminal against the surface of the electrical device, the edge or vertex on the tooth plate 2 away from the grounding terminal will move a distance and scrape on the surface of the electrical device, which is conducive to fully scraping the insulating layer of the electrical device, exposing the metal conductive part of the electrical device, so that the grounding terminal and the metal conductive part of the electrical device are fully in contact, ensuring the grounding quality.
[0041] In this embodiment, an existing structure on the tooth plate 2 is used as the sharp portion 211, so that the sharp portion 211 is not easy to fall off, which is beneficial to making the grounding terminal structure more stable and prolonging the service life of the grounding terminal.
[0042] Specifically, the sharp portion 211 is an edge of the tooth plate 2 away from the terminal body 1. Compared with using the vertex of the tooth plate 2 away from the terminal body 1 as the sharp portion 211, the edge has the advantage of slower wear, which is conducive to extending the service life of the grounding terminal.
[0043] The setting of the tooth plate 2 in this embodiment is as follows: first, the tooth plate 2 is placed against the side of the terminal body 1, and the tooth plate 2 is set parallel to the terminal body 1, and then the tooth plate 2 is rotated up and down, so that the upper and lower ends of the tooth plate 2 protrude from the upper and lower sides of the terminal body 1 respectively, until the tooth plate 2 and the terminal body 1 form an angle of 45°, and finally the tooth plate 2 is fixed to the terminal body 1 by welding or other fixing methods.
[0044] The angle formed between the tooth plate 2 and the terminal body 1 can be of other sizes and can be adjusted according to the situation.
[0045] In some other embodiments, a pointed or sharp object may be provided on the tooth plate 2 as the pointed portion 211 , such as a small blade.
[0046] In some specific embodiments, reference Figure 1 A plurality of tooth plates 2 are provided on the peripheral side of the terminal body 1 , and the plurality of tooth plates 2 are arranged in sequence around the circumference of the terminal body 1 .
[0047] The multiple tooth plates 2 are provided to further increase the friction between the grounding terminal and the connection piece and the surface of the electrical device, which is beneficial to improving the grounding stability and also beneficial to strengthening the contact between the grounding terminal and the metal conductive part inside the electrical device.
[0048] refer to Figure 1 , with the direction a indicated in the figure as the clockwise direction, the tooth plate 2 extends from bottom to top in the clockwise direction so that it is inclined with respect to the terminal body 1. The direction and inclination angle of each tooth plate 2 are consistent.
[0049] The utility model also provides a grounding structure, comprising the above-mentioned grounding terminal.
[0050] In some specific embodiments, reference Figures 1 to 3 ,and Figure 5 The connecting hole 11 is a non-circular hole. The grounding structure further includes a rivet 4. The rivet 4 includes a nail body 42. The nail body 42 is matched with the connecting hole 11 to limit the rotation of the rivet 4 after the rivet 4 is inserted into the connecting hole 11.
[0051] The rivet 4 in this embodiment is the above-mentioned connecting member. The rivet 4 and the connecting hole 11 restrict the rotation of the rivet 4, so that the grounding terminal is not easy to rotate, and the grounding stability is further improved.
[0052] In some other embodiments, the grounding structure includes screws and nuts, as long as the grounding terminal can be pressed tightly against the electrical device.
[0053] In some specific embodiments, reference Figure 1 and Figure 3 The connecting hole 11 is provided with two straight edges 111 and two arcuate edges 112 on its circumferential side. The two straight edges 111 and the two arcuate edges 112 are arranged alternately and connected end to end to enclose the connecting hole 11; the nail body 42 includes two planes 421 and two arcuate surfaces 422. The two planes 421 and the two arcuate surfaces 422 are arranged alternately and connected end to end to form the outer circumferential surface of the nail body 42.
[0054] Since the rivet bodies 42 of most rivets 4 on the market are cylindrical, to obtain the rivet 4 in this embodiment, it is only necessary to cut two planes 421 parallel to the axial direction of the rivet body 42 and to each other on the rivet body 42 of the original rivet 4. Correspondingly, the edge of the connecting hole 11 is also formed by two straight edges 111 and two arc edges 112 arranged alternately and connected end to end.
[0055] In some other embodiments, the cross-sectional shape of the shank 42 of the rivet 4 is rectangular, square, elliptical, diamond or other non-circular shapes, and the shape of the connecting hole 11 matches the shape of the shank 42 as long as the rotation of the rivet 4 can be restricted.
[0056] The utility model also provides a lamp, comprising the above-mentioned grounding structure, wherein one end of the grounding terminal is connected to a grounding wire 3 .
[0057] In some specific embodiments, reference Figures 4 to 6 The lamp also includes a lamp body 5, which is provided with a grounding hole 511. The grounding hole 511 is a non-circular hole matching the connecting hole 11, and the connecting hole 11 is directly opposite to the grounding hole 511; the grounding structure also includes a rivet 4, which includes a nail head 41, a nail body 42 and a nail tail 43. The nail body 42 is matched with the connecting hole 11, and the nail body 42 is passed through the connecting hole 11 and the grounding hole 511. The nail head 41 and the nail tail 43 are used to press the grounding terminal onto the lamp body 5.
[0058] like Figure 5 As shown, “51” in the figure refers only to the portion of the lamp body 5 that needs to be grounded, which is called the grounding portion 51 .
[0059] Before installation, the rivet 4 only has a rivet head 41 and a rivet body 42. After the rivet body 42 is inserted into the connection hole 11 and the grounding hole 511, the rivet 4 is tightened with a rivet pliers or other rivet 4 installation tools to form a rivet tail 43. The rivet head 41 and the rivet tail 43 clamp the grounding terminal and the grounding portion 51 of the lamp body 5 between them, completing the grounding operation.
[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
