Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the power detection wiring device 100 of some embodiments of this application includes a terminal block 110, a receiving cylinder 120, and a plug-in assembly 130. The receiving cylinder 120 is mounted on the terminal block 110, and the central axis of the receiving cylinder 120 is a first axis P. The plug-in assembly 130 includes a plurality of conductive components 131, which are disposed inside the receiving cylinder 120. The plurality of conductive components 131 are circumferentially spaced around the first axis P. Each conductive component 131 includes a conductive element 132 and an elastic element 133. The elastic element 133 elastically abuts against the conductive element 132 and the receiving cylinder 120 along the radial direction of the receiving cylinder 120. A plug-in space 1311 for accommodating a wire 200 is formed between the plurality of conductive elements 132. The conductive element 132 is used to abut against the surface of the wire 200 under the elastic action of the elastic element 133.

[0030] like Figure 2 As shown, the wire 200 includes a conductive wire 220 and an insulating layer 210 wrapped around the outside of the conductive wire 220. A section of the conductive wire 220 is stripped from the end of the wire 200 to expose the conductive wire 220, so that the wire 200 can be electrically connected to the conductive component 132. Different specifications of the wire 200 refer to changes in the outer diameter of the wire 200 and the diameter of the conductive wire 220.

[0031] The number of conductive components 131 is three, and the three conductive elements 132 are arranged circumferentially; the number of conductive components 131 can also be two, four, five, etc.

[0032] The power detection wiring device 100 of this application embodiment includes a plurality of conductive components 131. Each conductive component 131 includes a conductive element 132 and an elastic element 133. The plurality of conductive elements 132 are arranged circumferentially and are arranged together to hold the wire 200. Under the action of the elastic element 133, they elastically abut against the surface of the conductive wire 220 of the wire 200. It can adapt to wires 200 of different specifications and still have good conductive contact when the specifications of the wire 200 change, thereby ensuring good conductivity and improving the accuracy of power detection data.

[0033] The terminal block 110 is made of a conductive material, such as copper or aluminum. The thickness of the terminal block 110 extends along the first direction X, the length extends along the second direction Y, and the height extends along the third direction Z. The first direction X is parallel to the first axis P. The terminal block 110 has mounting holes, and the receiving cylinder 120 is installed in the mounting holes. Together with the plug-in assembly 130 and the fixing assembly 140 described below, they form a power detection connector 160.

[0034] The number of power detection connectors 160 can be multiple, for example, four power detection connectors 160 are arranged at intervals along the second direction Y; the number of power detection interfaces can also be one, two, five, etc.

[0035] The terminal block 110 is also connected to an output wire 111, which is electrically connected to the terminal block 110.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the outer surface of the conductive element 132 is provided with a movable rod 134, and the inner surface of the receiving cylinder 120 is provided with a sleeve 1214. The movable rod 134 and the sleeve 1214 are inserted into each other to achieve radial sliding cooperation between the conductive element 132 and the receiving cylinder 120.

[0037] The receiving cylinder 120 includes a cylinder body 121 and an end wall 122. The axial direction of the cylinder body 121 is a first axis P, and the radial direction is R. The cylinder body 121 has an inner surface 1211 and an outer surface 1212. The inner surface 1211 protrudes inward along the direction R to form a sleeve 1214. The conductive element 132 includes a sliding surface 1321 and a conductive surface 1322 on both sides along the direction R. The sliding surface 1321 is located on the outer side of the conductive element 132, and the conductive surface 1322 is located on the inner side of the conductive element 132. The sliding surface 1321 protrudes outward along the direction R to form a moving rod 134.

[0038] The cylinder 121 has a first receiving cavity corresponding to the conductive element 132. When the conductive element 132 moves outward along the direction R, the first receiving cavity is used to receive the conductive element 132.

[0039] Multiple moving rods 134 can be provided. For example, three moving rods 134 are provided on the sliding surface 1321. The three moving rods 134 are spaced apart along the first axis P. Three sleeves 1214 are provided on the inner surface 1211 of the cylinder. The sleeves 1214 are provided in a one-to-one correspondence with the moving rods 134. Alternatively, only one moving rod 134 can be provided.

[0040] This configuration allows the conductive element 132 to move along direction R, so that it can elastically abut against the surface of the wire 200 along direction R, ensuring electrical contact performance.

[0041] In other embodiments, a slide rail assembly may be provided on the end face of the first axis P of the conductive element 132, which restricts the movement of the conductive element 132 along the direction R by slidingly engaging with the end wall 122 of the receiving cylinder 120.

[0042] like Figure 3 As shown, in some embodiments of this application, the elastic element 133 is sleeved on the sleeve 1214.

[0043] The moving rod 134 is inserted into the sleeve 1214. The elastic element 133 is a straight spring. The elastic element 133 is sleeved on the outside of the sleeve 1214. The elastic element 133 abuts against the sliding surface 1321 and the inner surface 1211 of the cylinder in the direction R, so as to push the conductive element 132 to elastically abut against the wire 200 in the direction R.

[0044] This configuration allows for the installation of the elastic element 133 using the sleeve 1214, simplifying the construction of the receiving sleeve 120 and the conductive element 132.

[0045] In other embodiments, the elastic element 133 may also be set independently of the sleeve 1214, and the elastic element 133 may be assembled by a spring seat.

[0046] like Figure 2 As shown, in some embodiments of this application, the conductive component 131 further includes a wire 135 for conductively connecting the conductive element 132 and the terminal block 110.

[0047] With this configuration, the conductive component 132, the wire 135, and the terminal block 110 form a stable conductive path, ensuring the current transmission efficiency between the wire 200 and the terminal block 110, reducing the resistance that may be generated in the intermediate connection links, and improving the accuracy of power detection data.

[0048] like Figure 2 and Figure 6As shown, in some embodiments of this application, the receiving cylinder 120 includes a cylinder 121 and an end wall 122. The cylinder 121 has openings at both ends along the first axis P. The end wall 122 closes the rear opening of the cylinder 121. The end wall 122 is provided with a wire hole 1221. One end of the wire 135 is electrically connected to the conductive member 132, and the other end passes through the wire hole 1221 and is electrically connected to the terminal block 110.

[0049] The cylindrical body 121 includes a front opening 1213 and a rear opening at both ends along the first axis P. The front opening 1213 is used for inserting the power supply line 200, and the rear opening is closed by the end wall 122. The end wall 122 is provided with a plurality of wire holes 1221, and the wire holes 1221 correspond one-to-one with the wires 135 of each conductive element 132.

[0050] With this configuration, the wire hole 1221 provides a dedicated channel for the wire 135, reducing the risk of wear caused by direct contact between the wire 135 and the receiving cylinder 120. At the same time, it makes the arrangement of the wire 135 more regular, reducing the risk of circuit breakage caused by the wire 135 being tangled or compressed.

[0051] In other embodiments, the wire hole 1221 may also be provided on the cylinder 121.

[0052] like Figure 2 As shown, in some embodiments of this application, the front end of the conductive member 132 is provided with a guide portion 1323 to guide the wire 200 into the insertion space 1311.

[0053] The front end of the conductive element 132 refers to the side of the conductive element 132 near the front opening 1213. The conductive element 132 has a conductive surface 1324 on the side near the front opening 1213, and the conductive surface 1324 extends in a direction away from the first axis P in the direction near the front opening 1213.

[0054] This configuration allows for the formation of a flared structure at the front end of the plug-in assembly 130, which guides the wire 200 smoothly into the receiver cylinder 120 and into conductive contact with the conductive element 132. This reduces the risk of the end of the wire 200 rubbing against the conductive element 132 during insertion and improves wiring efficiency.

[0055] In other embodiments, a guide structure may be formed at the front opening 1213 to guide the wire 200 into the receiving tube 120.

[0056] like Figure 2 , Figure 4 and Figure 6As shown, in some embodiments of this application, the power detection wiring device 100 further includes a fixing component 140 and a locking nut 150. The fixing assembly 140 includes a plurality of locking blocks 141, which are disposed inside the receiving cylinder 120. The plurality of locking blocks 141 are circumferentially spaced around the first axis P. The outer surface of the receiving cylinder 120 is provided with a locking opening 1215. The locking blocks 141 slide in cooperation with the receiving cylinder 120 along the radial direction. The locking blocks 141 include a locking surface 1411 and a mating surface 1412. The locking surface 1411 is used to abut against the wire 200, and the mating surface 1412 is correspondingly disposed with the locking opening 1215. The locking nut 150 is sleeved on the receiving cylinder 120. The locking nut 150 is configured to be able to move along the first axis P to the locking position. When the locking nut 150 is in the locking position, the locking nut 150 acts on the mating surface 1412 through the locking opening 1215 so that the locking surface 1411 abuts against the wire 200.

[0057] The locking surface 1411 is used to abut against the insulation layer 210 of the wire 200 along the direction R. Multiple locking blocks 141 together circumferentially clamp the wire 200 to fix the position of the wire 200 and prevent the wire 200 from falling off or loosening. The locking block 141 slides with the receiving cylinder 120 along the direction R. The locking block 141 includes a locking surface 1411 and a mating surface 1412 on both sides along the direction R. The locking surface 1411 is set facing the insertion space 1311, and the mating surface 1412 is set correspondingly to the locking opening 1215.

[0058] The number of locking blocks 141 is five, and the five locking blocks 141 are spaced apart around the first axis P; the number of locking blocks 141 can also be three, four, six, etc.

[0059] The cylinder 121 has a second receiving cavity corresponding to the locking block 141. When the locking block 141 moves outward along the direction R, the second receiving cavity is used to receive the locking block 141.

[0060] By setting the fixing component 140, the wire 200 can be quickly fixed after being inserted into the plug space 1311. This not only improves wiring efficiency but also avoids poor contact caused by pulling the wire 200, ensuring the reliability of the conductive contact of the wire 200.

[0061] like Figure 4 As shown, in some embodiments of this application, the mating surface 1412 extends obliquely along the first axis P.

[0062] Specifically, the mating surface 1412 includes a first edge 1413 and a second edge 1414 on both sides of the first axis P. The second edge 1414 is provided corresponding to the locking position. The mating surface 1412 extends from the first edge 1413 to the second edge 1414 and extends obliquely away from the first axis P.

[0063] With this configuration, the mating surface 1412 of the locking block 141 forms an inclined surface. When it mates with the inner surface of the locking nut 150, it can convert the rotational force of the locking nut 150 into the radial tightening force of the locking block 141, thus enabling the wire 200 to be fixed simply and reliably.

[0064] In other embodiments, the mating surface 1412 may also be designed in other shapes to fit with the lock nut 150.

[0065] like Figure 2 and Figure 6 As shown, in some embodiments of this application, the receiving cylinder 120 further includes a limiting boss 123, which is used to abut against the locking nut 150 along the first axis P to restrict the locking nut 150 to the locked position.

[0066] The limiting boss 123 protrudes from the outer surface 1212 of the cylinder and extends circumferentially around the first axis P. The limiting boss 123 is located at the front end of the cylinder 121. The locking nut 150 moves forward along the first axis P until it abuts against the limiting boss 123.

[0067] The conductive element 132 and the locking block 141 are spaced apart along the first axis P, with the locking block 141 positioned closer to the limiting boss 123 than the conductive element 132.

[0068] This configuration limits the maximum screw-in depth of the locking nut 150, ensuring that the squeezing action of the locking nut 150 on the locking block 141 is within an effective range, thus improving the safety and stability of the locking action.

[0069] In some embodiments of this application, the locking nut 150 is threadedly engaged with the receiving sleeve 120.

[0070] The outer surface 1212 of the receiving cylinder 120 is provided with external threads, and the locking nut 150 is provided with internal threads. The locking nut 150 rotates around the first axis P to engage with the threaded connection of the receiving cylinder 120, and moves along the first axis P to the locking position.

[0071] With this configuration, the internal and external threads are matched, which can improve the tightness and stability of the assembly between the locking nut 150 and the receiving cylinder 120. During rotation, the locking nut 150 is not easy to slip off. The high-precision movement of the locking block 141 is controlled by the thread transmission, thereby realizing the high-precision clamping action of the control wire 200.

[0072] In other embodiments, the locking nut 150 and the receiving sleeve 120 can also be assembled by snap-fit.

[0073] like Figure 2 and Figure 7 As shown, in some embodiments of this application, each locking block 141 is slidably mounted on the receiving cylinder 120 radially via a slider assembly 143.

[0074] The receiving cylinder 120 has a groove 124 corresponding to each slider assembly 143. The slider assembly 143 includes a slider 1431, a slide rail 1432 and a spring 1433. The slide rail 1432 is installed in the corresponding groove 124. The slider 1431 is slidably disposed on the slide rail 1432 along the direction R. The slider 1431 is fixedly connected to the locking block 141. The spring 1433 abuts against the abutting surface 1241 of the groove 124 and the slider 1431 along the direction R, and is used to provide a force to the slider 1431 away from the first axis P.

[0075] This configuration allows the locking block 141 to move along direction R, thereby reliably securing the wire 200.

[0076] Furthermore, each locking block 141 is slidably engaged with the receiving cylinder 120 along the direction R via a slider assembly 143 on both sides of the first axis P, so that the locking block 141 is subjected to balanced force.

[0077] like Figures 1 to 7 As shown, the working principle of the power detection wiring device 100 in this application embodiment is as follows:

[0078] After the insulation layer 210 of the end of the wire 200 is stripped to expose the conductive wire 220, it is inserted into the inner cavity of the receiving tube 120.

[0079] During insertion, the wire 200 pushes the conductive element 132 to move outward along the direction R and compresses the elastic element 133. The reaction force of the elastic element 133 pushes the conductive element 132 to fit tightly against the surface of the wire 200, and the conductive surface 1324 makes conductive contact with the conductive wire 220.

[0080] Rotate the locking nut 150 to move it toward the limiting boss 123. The inner surface of the locking nut 150 presses against the mating surface 1412 of the locking block 141, causing the locking block 141 to move inward along the direction R and compress the spring 1433. The locking surface 1411 of the locking block 141 abuts against the insulation layer 210 of the wire 200. Multiple locking blocks 141 move together toward the first axis P until the wire 200 is tightly held. At this time, the locking nut 150 moves to the locking position and abuts against the limiting boss 123.

[0081] Conduct power testing;

[0082] After the power test is completed, rotate the locking nut 150 in the opposite direction to release the wire 200, which can then be pulled out.

[0083] In the above process, the plug-in component 130 can reliably and quickly achieve conductive connection under the action of the elastic element 133, and the fixing component 140 can reliably and quickly lock the wire 200 and release the wire 200 under the action of the locking nut 150. The whole process does not require additional tools, and the operation is efficient and convenient. It has good conductivity for wires 200 of different specifications, which improves the data accuracy and operation efficiency of power detection.

[0084] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0085] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
