Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, and more specifically, it relates to a grounding terminal. Background Technology

[0002] In automotive electrical systems, the grounding of the grounding harness (commonly known as "grounding") is crucial, providing a reference zero point and current loop for various electrical devices (such as sensors, actuators, and control units). Currently, grounding harnesses are often fixed to a fixed point using horizontal grounding terminals. However, using horizontal grounding terminals to fix the grounding harness to the battery's positive fuse box makes wiring cumbersome, causing excessive bending and occupying too much installation space. Summary of the Invention

[0003] The purpose of this invention is to provide an automotive grounding terminal to overcome the problem of cumbersome wiring when grounding harnesses are fixed to the positive battery fuse box via horizontal grounding terminals in the prior art.

[0004] This utility model is achieved using the following technical solution: a grounding terminal, comprising a horizontal plate and a vertical plate connected to the horizontal plate; the horizontal plate has a fixing hole and a downwardly extending anti-rotation rod is also installed on the horizontal plate; the vertical plate is provided with an upper clamping part, a middle clamping part and a lower clamping part at intervals from top to bottom; the upper clamping part includes upper clamping plates arranged opposite to each other on both sides, and the two upper clamping plates are respectively connected to the left and right ends of the vertical plate; the middle clamping part includes lower clamping plates arranged opposite to each other on both sides, and the two lower clamping plates are respectively connected to the left and right ends of the vertical plate; the lower clamping part includes a sleeve, the upper end of which is connected to the vertical plate; a clamping threaded hole is provided on the circumferential surface of the sleeve, and a clamping bolt is installed in the clamping threaded hole.

[0005] Furthermore, the anti-rotation rod is fixedly connected to the front end of the cross plate.

[0006] Furthermore, the upper clamping plates on both sides are connected to the vertical plate by bending; the lower clamping plates on both sides are connected to the vertical plate by bending.

[0007] Furthermore, the distance D1 between the upper clamping plates on both sides is less than the distance D2 between the lower clamping plates on both sides.

[0008] Furthermore, the length L1 of the upper clamping plate is greater than the length L2 of the lower clamping plate.

[0009] Furthermore, a clamping nut is welded to the inside of the clamping threaded hole of the sleeve.

[0010] Furthermore, the horizontal and vertical plates are connected by bending.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by designing the grounding terminal in an L-shape, simplifies the grounding harness installation process by requiring only the upper, middle, and lower clamping parts to fix it to the vertical plate. This makes wiring easier, reduces the space occupied by the grounding harness, and eliminates the need for bending at the end of the grounding harness near the battery's positive fuse box. In existing technology, when the grounding harness is fixed to the battery's positive fuse box using a horizontal grounding terminal, one end of the grounding harness needs to be close to the horizontal fixing hole in this utility model. This often results in excessive bending of the grounding harness, a problem effectively solved by this utility model.

[0013] 2. This utility model provides a very secure fixation for the grounding wire harness by having an upper clamping part, a middle clamping part, and a lower clamping part arranged sequentially from top to bottom on the vertical plate. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0018] A grounding terminal includes a horizontal plate 1, which is bent downward to form a vertical plate 2, and the horizontal plate 1 and the vertical plate 2 have an L-shaped structure.

[0019] The horizontal plate 1 is used to fix the present invention to the positive terminal fuse box of the battery. The horizontal plate 1 has a fixing hole 3 and a downwardly extending anti-rotation rod 4 is also installed on the horizontal plate 1. The anti-rotation rod 4 is fixedly connected to the front end of the horizontal plate 1.

[0020] In application, the battery positive terminal fuse box is provided with a fixing threaded hole that mates with the fixing hole 3 and an anti-rotation hole that mates with the anti-rotation rod 4. When fixing the horizontal plate 1, first insert the anti-rotation rod 4 on the horizontal plate 1 into the anti-rotation hole of the battery positive terminal fuse box, then align the fixing hole 3 with the fixing threaded hole on the battery positive terminal fuse box, and finally insert the bolt into the fixing hole 3 and the fixing threaded hole and tighten it.

[0021] The vertical plate 2 is provided with an upper clamping part, a middle clamping part and a lower clamping part at intervals from top to bottom.

[0022] The upper clamping part includes upper clamping plates 5 arranged opposite to each other on both sides. The upper clamping plates 5 on both sides are connected to the left and right ends of the vertical plate 2, and the upper clamping plates 5 on both sides are connected to the vertical plate 2 by bending. The upper clamping part of this utility model is used to press the stripped copper wire of the grounding wire bundle. When fixing, the upper clamping plates 5 on both sides are bent inward to press the stripped copper wire of the grounding wire bundle.

[0023] The intermediate clamping part includes two opposing lower clamping plates 6, which are connected to the left and right ends of the vertical plate 2, respectively, and are connected to the vertical plate 2 by bending. The lower clamping part of this invention is used to press the outer sheath of the grounding wire harness. During fixing, the two lower clamping plates 6 are bent inwards to press the outer sheath of the grounding wire harness.

[0024] The lower clamping part includes a sleeve 7, the upper end of which is connected to the vertical plate 2. A clamping threaded hole is formed on the circumferential surface of the sleeve 7, and a clamping bolt 8 is installed in the clamping threaded hole. A clamping nut 9 is welded to the inner side of the clamping threaded hole on the sleeve 7, and the internal thread of the clamping nut 9 communicates with the clamping threaded hole. The clamping bolt 8 and the sleeve 7 of this utility model are used to further fix the grounding wire harness, effectively preventing the grounding wire harness from being pushed outward by the upper and lower clamping parts during the later fixing process. Secondly, the clamping bolt 8 and the sleeve 7 also have a good pre-clamping effect, making it more convenient to bend the upper clamping plate 5 and the lower clamping plate 6 on both sides laterally.

[0025] The process of using this utility model is as follows: First, place the horizontal plate 1 on the positive terminal fuse box of the battery. Then, insert the anti-rotation rod 4 on the horizontal plate 1 into the anti-rotation hole of the positive terminal fuse box of the battery. Align the fixing hole 3 with the fixing threaded hole on the positive terminal fuse box of the battery. Then, insert the bolt into the fixing hole 3 and the fixing threaded hole and tighten it.

[0026] Next, insert the stripped ground wire harness through the sleeve 7 between the lower clamping plates 6 and the upper clamping plates 5 on both sides, ensuring the stripped copper wire at the front end of the ground wire harness is between the upper clamping plates 5. Then, pass the clamping bolt 8 through the sleeve 7 and the clamping nut 9, and clamp the ground wire harness with the clamping bolt 8, which serves as a pre-tightening measure. Then, bend the lower clamping plates 6 inwards to press the outer sheath of the ground wire harness tightly, and bend the upper clamping plates 5 inwards to press the stripped copper wire of the ground wire harness tightly. This completes the fixing of the ground wire harness.
