It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0035] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] See Figure 1-9 The present invention provides an electrical power transmission component, comprising a first cable 11 and a second cable 31 arranged in a row, and a first terminal 13 and a second terminal 32 respectively electrically connected to the ends of the first cable 11 and the second cable 31. The other ends of the first terminal 13 and the second terminal 32 are connected to each other to realize the conductive connection between the first cable 11 and the second cable 31.

[0037] Furthermore, a fixing bolt 14 is inserted inside the first terminal 13, and a locking bolt 35 is inserted inside the second terminal 32. The fixing bolt 14 is threaded to the inner wall of the corresponding first terminal 13, and a locking hole 141 is provided axially inward at the end of the fixing bolt 14 facing the locking bolt 35. The end of the locking bolt 35 facing the fixing bolt 14 is inserted into the locking hole 141 and threaded to the inner wall of the locking hole 141. The external threads of the fixing bolt 14 and the locking bolt 35 have opposite directions of rotation. (Obviously, in other scenarios, when the fixing bolt is inserted inside the second terminal and the locking bolt is inserted inside the first terminal, the fixing bolt is threaded to the inner wall of the corresponding second terminal.)

[0038] During assembly, the first cable 11, the first terminal 13, the second terminal 32, and the second cable 31 can be fixedly connected in one go by the locking bolt 35, saving time and effort in product assembly. At the same time, the external threads of the fixing bolt 14 and the locking bolt 35 are opposite, which can make the fixing bolt 14 tend to continue to tighten when the locking bolt 35 is turned, preventing the fixing bolt 14 from loosening. The two work together to achieve a self-tightening effect.

[0039] Specifically, in the embodiments provided by this utility model, such as Figure 5-9As shown, based on the assembly environment requirements and the predetermined assembly sequence, both the first terminal 13 and the second terminal 32 are provided with holes, namely the first connecting hole 15 and the second connecting hole 33, respectively. The fixing bolt 14 is inserted into the hole of the first terminal 13, i.e. the first connecting hole 15, and is threadedly connected to the inner wall of the hole of the first terminal 13, i.e. the first connecting hole 15. The locking bolt 35 is inserted into the hole of the second terminal 32, i.e. the second connecting hole 33, and the end of the locking bolt 35 facing the fixing bolt 14 is connected to the locking hole 141 of the fixing bolt 14.

[0040] To prevent contact with the first terminal 13 when not assembled, such as Figure 7-9 As shown, in this embodiment, a protective sleeve 17 is provided in the first connection hole 15 on the side of the first terminal 13 facing the second terminal 32. The protective sleeve 17 protrudes from the end face of the first terminal 13 and can be inserted into the hole of the second terminal 32, i.e., the second connection hole 33. An avoidance hole 172 is provided through the protective sleeve 17 along the axial direction. The end of the locking bolt 35 facing the fixing bolt 14 passes through the avoidance hole 172 and is connected to the locking hole 141 of the fixing bolt 14.

[0041] In order to position the anti-touch sleeve 17, a stop structure is provided between the outer wall of the anti-touch sleeve 17 and the inner wall of the hole of the first terminal 13, i.e., the first connecting hole 15, to prevent the anti-touch sleeve 17 from coming out of the hole of the first terminal 13, i.e., the first connecting hole 15. The end of the fixing bolt 14 in the hole of the first terminal 13, i.e., the first connecting hole 15, abuts against the end of the anti-touch sleeve 17.

[0042] Specifically, in this embodiment, such as Figure 9 As shown, the blocking structure includes a first stop 151 disposed on the inner wall of the hole in the first terminal 13, i.e., the first connecting hole 15, and a second stop 171 disposed on the outer wall of the anti-contact sleeve 17. The first stop 151 and the second stop 171 are axially blocked to prevent the anti-contact sleeve 17 from coming out of the hole in the first terminal 13, i.e., the first connecting hole 15.

[0043] In other embodiments, the above-mentioned blocking structure may also be a snap-fit ​​structure provided between the outer wall of the anti-collision sleeve and the inner wall of the hole of the first terminal, i.e., the first connecting hole. For example, the inner wall of the hole of the first terminal, i.e., the first connecting hole, is provided with a groove, and the outer wall of the anti-collision sleeve is provided with a boss. The boss and the groove form a snap-fit ​​structure that can be engaged.

[0044] Both the first cable 11 and the second cable 31 are rigid cables. To facilitate the connection of the first cable 11 and the second cable 31 to the first terminal 13 and the second terminal 32, respectively, the ends of the first cable 11 and the second cable 31 are respectively provided with a first fixing hole and a second fixing hole 34. The fixing bolt 14 and the locking bolt 35 pass through the first fixing hole and the second fixing hole 34, respectively, and then pass through the first terminal 13 and the second terminal 32, respectively, and are screwed together. After the fixing bolt 14 passes through the first fixing hole and enters the first terminal 13, the fixing bolt 14 fixes and electrically connects the first cable 11 and the first terminal 13. At this time, the locking bolt 35 can pass through the second fixing hole 34 and the second terminal 32 and connect to the locking hole 141, thereby fixing and electrically connecting the second cable 31 and the second terminal 32, and simultaneously achieving the fixed connection of the first cable 11, the first terminal 13, the second terminal 32, and the second cable 31 in one operation.

[0045] like Figure 4-7 As shown, in this embodiment, considering the layout position of the first cable 11, the first terminal 13 can correspond to the position of the second terminal 32. The end of the first cable 11 is fixedly connected to the first adapter terminal 12. The first adapter terminal 12 is provided with a third fixing hole 16. Since the first adapter terminal 12 and the first cable 11 are fixedly connected to each other as an integral structure by welding or other means, the third fixing hole 16 is actually equivalent to the first fixing hole mentioned above. The fixing bolt 14 passes through the third fixing hole 16 and then passes into the first terminal 13.

[0046] In other embodiments, taking into account the layout position of the second cable, the end of the second cable is fixedly connected to a second adapter terminal. The second adapter terminal is provided with a fourth fixing hole, which is actually equivalent to the second fixing hole mentioned above. The locking bolt passes through the fourth fixing hole and then through the second terminal. It can be understood that the first adapter terminal and the second adapter terminal mentioned above can coexist or be selected to coexist according to the actual layout needs.

[0047] The first terminal 13 and the second terminal 32 are both made of copper / copper alloy. The first adapter terminal 12 is made of copper / copper alloy, and the second adapter terminal 12 is also made of copper / copper alloy. The locking bolt 35 and the fixing bolt 14 are both made of iron / iron alloy. The locking bolt 35 and the fixing bolt 14 made of iron / iron alloy can achieve a firm connection and prevent the connection performance from being affected by the softness of the material and easy deformation.

[0048] The conductor portion of the first cable 11 is made of aluminum / aluminum alloy, and the first adapter terminal 12 is welded and fixed to the conductor portion at the end of the first cable 11.

[0049] The first adapter terminal 12 can be pre-riveted or welded to the first terminal 13, or it can be directly fixed by the fixing bolt 14. In this embodiment, the first adapter terminal 12 and the first terminal 13 are directly fixed by the fixing bolt 14. The second cable 31 and the second terminal 32 can be pre-corresponded but not fixedly connected, and then fixed together by the locking bolt 35. Alternatively, the second terminal 32 and the second cable 31 can be pre-riveted or welded to each other. In the case where the second cable 31 and the second terminal 32 are pre-corresponded but not fixedly connected, the locking bolt 35 can complete the fixed connection of the first adapter terminal 12, the first terminal 13, the second terminal 32 and the second cable 31 in one go, which is particularly effective. In this embodiment, the second cable 31 and the second terminal 32 are pre-corresponded but not fixedly connected, and then the first adapter terminal 12, the first terminal 13, the second terminal 32 and the second cable 31 are fixedly connected in one go by the locking bolt 35.

[0050] An embodiment of this utility model also provides a connector, such as... Figure 1-3 As shown, it includes a plug 1 and a socket 3 for plugging and connecting. The plug 1 and socket 3 are located on the inner and outer sides of the mounting panel 2, respectively. It also includes the power transmission component as described above, wherein the first terminal 13 and the second terminal 32 are located in the plug 1 and the socket 3, respectively. The end of the first cable 11 passes through the plug 1 and is electrically connected to the first terminal 13. The end of the second terminal 32 opposite to the first terminal 13 extends out of the socket 3 and is electrically connected to the end of the second cable 31.

[0051] During assembly, first, open the housing of plug 1 and insert the first terminal 13 and the first cable 11. Then, pass the fixing bolt 14 through the third fixing hole 16 and into the first connecting hole 15 to securely connect the first adapter terminal 12 and the first terminal 13. Next, plug 1 into socket 3, at which point the first terminal 13 and the second terminal 32 correspond. Then, pass the locking bolt 35 sequentially through the second fixing hole 34 and the second connecting hole 33 until the end of the locking bolt 35 facing the fixing bolt 14 is inserted into the locking hole 141 and threadedly connected to the inner wall of the locking hole 141. At this point, the locking bolt 35 secures the second cable 31 and the second terminal 12. 2. The first terminal 13 and the first adapter terminal 12 are fixedly connected, that is, the second cable 31, the second terminal 32, the first terminal 13, and the first cable 11 are fixedly connected and can conduct electricity. Thus, the first cable 11, the first terminal 13, the second terminal 32, and the second cable 31 can be fixedly connected in one go by the locking bolt 35, which saves time and effort in assembly. At the same time, since the external threads of the fixing bolt 14 and the locking bolt 35 are opposite, when the locking bolt 35 is tightened, the fixing bolt 14 tends to continue to tighten, preventing the fixing bolt 14 from loosening. The two work together to achieve a self-tightening effect, and there will be no problem of loose connection.
