Abstract
Description
Technical Field
[0001] The utility model relates to a new type of grounding contact. Background Art
[0002] Grounding contacts are important components used to achieve the grounding function in electrical systems. They are usually connected to grounding wires or grounding plates to ensure the safety and stability of electrical equipment. During actual use, the original grounding contacts were used to connect to a long strip-shaped grounding copper bar to achieve the required effect. However, the length of the grounding copper bar needs to be preset in advance and cannot be adjusted according to the actual application scenario, thus limiting the application of the product. Moreover, the design of the original grounding copper bar and grounding contacts requires a certain amount of copper raw material, thereby increasing the cost. Therefore, designing a grounding contact that saves costs, is flexibly adjustable, and is suitable for various application scenarios is the research direction of the present utility model.

[0005] A new type of grounding contact includes a first contact, with first contact ends provided at both ends thereof. A first fixed end is formed between the two first contact ends. First holes are opened on both sides of the first fixed end near the first contact ends.
[0006] A second contact, with a second contact end provided at one end thereof, a second fixed end connected to the second contact end, and second holes equidistantly spaced on the second fixed end.
[0007] Wherein, the first contact and the second contact can be combined and spliced, so as to form a grounding contact of any length.
[0008] As a further improvement, the shapes of the first contact end and the second contact end are trapezoidal, square or rectangular.
[0009] As a further improvement, both the first contact end and the second contact end are trapezoidal.
[0010] As a further improvement, both the first contact and the second contact are made of copper.
[0011] As a further improvement, the conductivity of the copper-made first contact and second contact is 54% MS / m or less than or equal to 100% MS / m.
[0012] As a further improvement, transverse bolt holes are provided on both the first contact end and the second contact end, and the bolt holes correspond to each other, so that the first contact end and the second contact end are locked and fixed transversely by bolts.

[0028] Embodiment 1:
[0029] Referring to Figure 1-2 As shown, a new type of grounding contact includes a first contact 1, with first contact ends 11 provided at both ends thereof. A first fixed end 10 is formed between the two first contact ends 11. First holes 12 are provided at both ends of the first fixed end 10 on the side close to the first contact ends 11.
[0030] A second contact 2, with a second contact end 21 provided at one end thereof, a second fixed end 20 connected to the second contact end 21, and second holes 22 equally spaced and provided on the second fixed end 20.
[0031] Among them, the first contact 1 and the second contact 2 can be combined and spliced, so as to form a grounding contact of any length.
[0032] The shapes of the first contact end 11 and the second contact end 21 are trapezoidal, square or rectangular. In one of the embodiments, both the first contact end 11 and the second contact end 21 are trapezoidal. The advantage of such a design is that it can save the amount of copper used and save a certain cost.
[0033] The first contact 1 and the second contact 2 are both made of copper; the conductivity of the first contact 1 and the second contact 2 made of copper is 54% MS / m or less than or equal to 100% MS / m.
[0034] Transverse bolt holes (not shown in the figure) are provided on both the first contact end 11 and the second contact end 21, and the bolt holes correspond to each other, so that the first contact end 11 and the second contact end 21 are locked and fixed transversely by bolts.
[0035] Further, the bolts are installed transversely (horizontally) in the bolt holes to connect and fix the first contact end 11 and the second contact end 21, and bolts are vertically connected to the first fixed end 10 and the second fixed end 20 to fix the product. Among them, the combination of horizontal and vertical bolts can provide a more stable connection and reduce the risk of connection loosening caused by single-direction stress.
[0036] A new type of grounding contact also includes an installation process flow, which is as follows:
[0037] S1. Prepare the required first contact 1 and second contact 2, and equip fixing parts, materials such as bolts, nuts or gaskets;
[0038] S2. Combine the actual application scenario, connect the two ends or three sections of the grounding contacts, and connect the first contact 1 and the second contact 2 with materials such as bolts;
[0039] S3. Clean the installation site to ensure that the installation area is clean and free of obstacles for convenient construction operations;
[0040] S4. Perform positioning and marking at the predetermined position according to the construction drawings or design requirements;
[0041] S5. Connect the grounding wire to the grounding contact to ensure the reliability of the electrical connection;
[0042] S6. Conduct a resistance test on the grounding system to ensure that the grounding resistance value meets the specification requirements;
[0043] S7. Mark the grounding contact for easy identification and maintenance;
[0044] S8. After completion of the installation, conduct a careful inspection to ensure that all connections meet the design and safety specifications, and then conduct acceptance;
[0045] S9. Record the key information during the installation process, including material usage, installation location, test results, etc., for subsequent maintenance and inspection.
[0046] Among them, in step S2, if the grounding contact is installed on the shell of the electrical equipment, it can be directly fixed by bolts to ensure electrical safety; further, in step S2, if the grounding contact is installed inside the electrical equipment, in order to avoid the grounding contact occupying too much space, the length of the grounding contact can be adjusted according to actual needs, and then connected to the circuit board or other components. Therefore, in the actual application process, the grounding contact can be adjusted according to the change of space to increase the application environment.
[0047] It should be noted that in this case, the original separate grounding contact is combined with the grounding copper bar 3 to form a new type of grounding contact, and the new type of grounding contact is divided into multiple segments. In actual application, the length can be adjusted according to the actual situation. At the same time, in order to better distinguish the existing products from the original ones, the copper consumption of the new type of grounding contact is defined as C.
[0048] Comparative Example 1:
[0049] Refer to Figure 3-4 , the difference from Embodiment 1 is that the third contact 4 includes a third fixed end 40 and a third contact end 41. The third fixed end 40 is installed on the grounding copper bar 3 through a fixing member 5 and a third hole 42, and the grounding copper bar 3 is connected to the electrical equipment or the ground through a bolt hole 30; the grounding contact and the grounding copper bar 3 are two separate entities, so the copper consumption is relatively high. Therefore,
[0050] define the copper consumption of the third contact 4 as A, the copper consumption of the grounding copper bar 3 as B, and C < A + B. Thus, it can reduce the copper consumption for the factory and save a certain amount of cost.
[0051] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
