Description

Technical Field

[0001] This utility model relates to a terminal fastening component. Background Technology

[0002] In the prior art, some electric vehicles have terminal fastening components installed on the bolt-type terminals of their battery packs. These terminal fastening components include an electrically insulating body, a conductive plate embedded in the body with one end exposed from the front of the body, and a cover rotatably connected to one side of the body via a hinge, which covers the exposed portion of the conductive plate.

[0003] The cover can be switched between two states by rotation: a closed state where the exposed portion is covered, and an open state where the exposed portion is not covered. Additionally, hooks and blocks are provided on both the cover and the main body to maintain the closed state of the cover.

[0004] When switching the cover to the closed state, the hook needs to pass over the locking block and engage with it. However, the operation of making the hook pass over the locking block is difficult and time-consuming, resulting in low efficiency in closing the cover. Utility Model Content

[0005] In view of the above situation, the purpose of this utility model is to provide a terminal fastening component that can improve the efficiency of closing the cover.

[0006] As a technical solution to the above-mentioned technical problems, this utility model provides a terminal fastening component. The terminal fastening component includes an electrically insulating body, a conductive plate embedded in the body with one end of its front surface protruding from the front of the body to the outside, and a cover rotatably connected to one side of the body via a hinge and capable of covering the exposed portion of the conductive plate. The cover can switch between a closed state with the exposed portion covered and an open state without covering the exposed portion. Hooks and blocks for maintaining the closed state of the cover are respectively provided on the cover and the body. The hooks are frame-shaped and elastically deformable from their roots, with their inner corners at the front end being chamfered. The blocks are protrusions that can be embedded in the inner opening of the hooks and are positioned on the body corresponding to the hooks.

[0007] Based on the above-described structure of this utility model, during the process of switching the cover from an open state to a closed state, the chamfer formed at the inner corner of the front end of the hook will contact the corner of the protruding front end of the locking block. At this time, the load pressing the cover to close it will change direction, thereby allowing the hook to bend and deform from its root and pass over the protrusion that serves as the locking block. After passing over the protrusion, the hook returns to its original shape, while the protrusion is embedded in the inner opening of the hook, thus firmly maintaining the closed state of the cover. That is, during the process of switching the cover from an open state to a closed state, the hook can easily pass over the locking block and engage with it, thereby improving the operational efficiency of closing the cover.

[0008] In addition, in the terminal fastening component of the present invention, it is preferable that the corner of the front side of the main body of the card block is chamfered.

[0009] Based on this structure, the hook can more easily pass over the block and engage with it. Attached Figure Description

[0018] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0019] Figure 1 is a front view of the terminal fastening member of this embodiment, Figure 2 is a view along the direction of arrow (2) in Figure 1, Figure 3 is a view along the direction of arrow (3) in Figure 1, and Figure 4 is a view along the direction of arrow (4) in Figure 1.

[0020] As shown in Figures 1 and 2, the terminal fastening component 1 of this embodiment includes a main body 2, a conductive plate 3, and a cover 4. Here, both the main body 2 and the cover 4 are made of an electrically insulating material (such as synthetic resin).

[0021] The main body 2 is provided with a mounting plate 21 for fixing the terminal fastening member 1 to a designated position. The mounting plate 21 is provided with a through hole 21a for inserting a bolt or screw (not shown) for installation.

[0022] The conductive plate 3 is made of a conductive material (such as copper) and is embedded in the main body 2. The conductive plate 3 has a strip-shaped portion 31, the lower end of the front side of which (equivalent to "one end" in this utility model) protrudes to the outside from the opening window 22 of the main body 2. The opening window 22 is configured to be recessed in the lower part of the front side of the main body 2 toward the back side of the main body 2.

[0023] The cover 4 is rotatably connected to one side of the main body 2 via a hinge 5. The cover 4 can cover the portion (exposed portion 33) of the strip-shaped part 31 of the conductive plate 3 that is exposed from the opening window 22. The hinge 5 is made of an electrically insulating material (such as synthetic resin).

[0024] More specifically, the cover 4 includes a rectangular plate-shaped cover body 41 and upright wall portions 42 provided on the four sides of the cover body 41. The size of the cover body 41 is set to cover the exposed portion 33. By rotating the cover 4, the cover 4 can be switched between two states: a closed state that covers the exposed portion 33 of the conductive plate 3 (see Figures 5-7), and an open state that does not cover the exposed portion 33 (see Figures 1-4).

[0025] As shown in Figure 2, a through hole 23 is provided on the main body 2, and a through hole 34 is provided on the conductive plate 3. These two through holes (23, 34) are connected and aligned in the thickness direction of the main body 2 (the direction perpendicular to the paper in Figure 1). That is, through holes 23 and 34 extend from the exposed portion 33 on the front side of the strip portion 31 of the conductive plate 3 to the back side of the main body 2.

[0026] Although not illustrated here, after the bolt-type terminal of the battery pack mounted on the electric vehicle is inserted into the through hole 23 and through hole 34, the front end of the bolt-type terminal protruding from the through hole 34 is screwed into the nut through a washer made of conductive material, thereby making the bolt-type terminal electrically connected to the conductive plate 3.

[0027] The front end portion, the washer, and the nut of the bolt-type terminal block can all be covered by the cover body 4. To avoid interference with the front end portion of the bolt-type terminal block, a terminal clearance portion 44 is provided in the middle portion of the cover body 41.

[0028] At the other end of the strip portion 31 of the conductive plate 3, that is, the end opposite to the exposed portion 33, a bent portion 32 is formed. As shown in FIG3, the bent portion 32 bends 90° toward the back side of the main body 2 together with the main body 2, and a bolt terminal 24 is fixedly connected to its top, and the bolt terminal 24 is electrically connected to the conductive plate 3.

[0029] More specifically, the bolt terminal 24 is connected to the bent portion 32 of the conductive plate 3 in a state where it protrudes outward from the body 2 perpendicular to the central axis of the through hole 23 of the body 2 and the through hole 34 of the conductive plate 3 (or the bolt-type terminal block).

[0030] In addition, while a hook 43 is provided on the cover 4, a locking block 25 is provided on the main body 2. The hook 43 and the locking block 25 are used to keep the cover 4 in the closed state.

[0031] In this embodiment, the hook 43 is configured as a frame and can be elastically deformed by bending from the root. The hook 43 is provided on a side 42a (i.e., the lower side in FIG1) of the cover 4 that is perpendicular to the pivot of the hinge 5.

[0032] The latch 25 is configured as a protrusion that can be inserted into the inner opening of the frame-shaped latch 43, and is set on the main body 2 at a position corresponding to the latch 43, that is, at the bottom below the opening window 22 of the main body 2.

[0033] Furthermore, in this embodiment, as shown in FIG4, the inner corner of the front end of the frame-shaped hook 43 and the corner near the hinge are both machined into chamfers 45. The chamfer 45 is, for example, a slope.

[0034] Furthermore, in this embodiment, as shown in FIG8 described later, the corners on the front side of the main body of the card block 25 are also chamfered 26. This chamfer 26 is, for example, a slope.

[0035] Next, referring to Figures 5-8, the operation steps for closing the cover 4 will be explained. Figure 5 is a diagram showing the closed state of the cover 5 of the terminal fastening component 1, Figure 6 is a view along the direction of arrow (5) in Figure 5, Figure 7 is a view along the direction of arrow (6) in Figure 5, and Figure 8 is a diagram showing the intermediate state of the cover 5 of the terminal fastening component 1 during the process of switching from the state shown in Figure 1 to the state shown in Figure 7.

[0036] First, for example, after the terminal fastening component 1 is installed on the bolt-type terminal (not shown), as indicated by the hollow arrows in Figures 2 and 4, the cover 4 of the terminal fastening component 1 is rotated from the open state shown in Figures 1-4, with the hinge 5 as the fulcrum, toward the main body 2.

[0037] During the rotation, it will reach the state shown in Figure 8. At this time, the back of the cover body 41 of the cover body 4 is pressed further towards the body 2.

[0038] Thus, as shown in Figures 6 and 7, the cover 4 can close the opening window 22 of the main body 2 while covering the exposed portion 33 of the conductive plate 3 from the outside.

[0039] During the process of rotating the cover 4 to switch from the open to the closed state, the chamfer 45 of the hook 43 contacts the chamfer 26 of the protrusion that serves as the locking block 25, thus allowing it to be smoothly guided. Furthermore, as the cover 4 is pressed towards the closing direction, the direction of the load changes, causing the hook 43 to bend and deform from its base away from the protrusion (locking block 25) and smoothly pass over the protrusion that serves as the locking block 25. After passing over the protrusion, the hook 43 returns to its original shape, and the protrusion that serves as the locking block 25 is embedded in the inner opening of the frame-shaped hook 43. Thus, the closed state of the cover 4 can be securely maintained.

[0040] As described above, based on the structure of the terminal fastening component 1 of the above embodiment of the present invention, during the process of switching the cover 4 from the open state to the closed state, the hook 43 can easily pass over the locking block 25 and engage with the locking block 25, thereby improving the operational efficiency of closing the cover 4.

[0041] However, this utility model is not limited to the embodiments described above, and various applications and modifications can be implemented.

[0042] For example, in the above embodiment, the corner of the front side of the protrusion of the card block 25 is described as being chamfered 26. However, the present invention is not limited to this and the corner of the card block 25 may not be chamfered.

[0043] In addition, in the above embodiment, the chamfer 45 of the hook 43 and the chamfer 26 of the block 25 are configured as slopes, but the present invention is not limited to this, and the chamfer 45 and the chamfer 26 can also be configured as curved surfaces.
