Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle wiring harnesses, and in particular to an aluminum alloy new energy vehicle cable harness. Background Art

[0002] The automotive wiring harness is the main body of the automotive circuit network. Its main function is to connect the power supply with electrical appliances and switches to ensure the reliable transmission of current or signals. The number of cable harnesses used in new energy vehicles far exceeds that of traditional fuel vehicles. Due to the presence of a large number of battery modules and cable harnesses, the body of new energy vehicles is often heavier. Therefore, many new energy vehicles currently use aluminum alloy materials for the main body of the body and even the main body of the cable harness to reduce weight.

[0003] However, the cable harnesses currently used in new energy vehicles still use traditional connectors, which makes it difficult to inspect and repair each branch line on the entire harness. Once a branch line fails, the entire cable harness can only be replaced, which greatly increases the cost. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an aluminum alloy new energy vehicle cable harness in view of the above-mentioned technical deficiencies, which can easily perform individual inspection and replacement of each branch line on the cable harness to reduce costs.

[0005] The technical solution adopted by the present invention is: to provide an aluminum alloy new energy vehicle cable harness, comprising a plurality of branch line bodies, the ends of the plurality of branch line bodies are connected through a plug assembly;

[0006] The plug assembly comprises a plug shell arranged along the front-to-back direction; an external socket is evenly embedded in the front end of the plug shell; a mounting groove is provided at the rear end of the plug shell; a connecting plate is slidably inserted in the mounting groove along the front-to-back direction; the connecting plate is an elastic steel sheet structure; first sliding grooves are provided at both upper and lower ends of the rear of the plug shell along the front-to-back direction; the first sliding groove is connected to the mounting groove; the rear end of the first sliding groove passes through the rear end of the plug shell; second sliding grooves are provided at both left and right ends of the rear of the plug shell along the front-to-back direction; the second sliding groove is connected to the mounting groove; paddles are fixed at both upper and lower ends of the connecting plate; the connecting plate Slide bars are fixed on both ends of the connecting plate; the paddles slide through the first slide slot one by one; the slide bars slide through the second slide slot one by one; a stopper is fixed on the end of the slide bar away from the connecting plate; a plurality of terminal blocks are evenly distributed on the rear side of the connecting plate; the terminal blocks and the connecting plate are connected through a detachable module; the rear end of the terminal block is connected to the end of the branch line body one by one; when the paddle abuts against the front end of the first slide slot, the front end of the terminal block is connected to the rear end of the external plug sleeve one by one; a limiting component for positioning the paddle at the front end of the first slide slot is provided on the plug housing;

[0007] The limiting component includes a limiting plate placed on the upper end of the plug shell; an alignment slot is opened on the limiting plate; the alignment slot is correspondingly plugged into the paddle on the upper end of the connecting plate; a blocking angle is fixed to the rear part of the upper end of the plug shell; the blocking angle is used to block the rear end and left and right ends of the connecting plate; the front part of the upper end of the plug shell is used to block the front end of the limiting plate.

[0008] To further optimize the technical solution, the detachable module of the aluminum alloy new energy vehicle cable harness includes a conductive column fixed at the front end of the terminal block; the conductive column is threadedly connected to the connecting plate; when the paddle abuts against the front end of the first slide groove, the front end of the conductive column is inserted into the corresponding external socket.

[0009] To further optimize the technical solution, extended retaining frames are fixed on the left and right ends of the limiting plate of the aluminum alloy new energy vehicle cable harness; when the alignment slots and the paddles are correspondingly plugged in, the extended retaining frames block the slide bar at the front end of the second slide groove one by one.

[0010] To further optimize the technical solution, a supporting rubber sleeve is inserted into the rear end of the installation slot of the aluminum alloy new energy vehicle cable harness; limiting holes are distributed on the supporting rubber sleeve; the limiting holes are plugged into the terminal blocks in a one-to-one correspondence.

[0011] The beneficial effects of the present invention are:

[0012] 1. By slidingly connecting the connecting plate and the mounting groove, the connecting plate can be easily controlled to slide in the mounting groove by sliding the paddle through the first sliding groove and the slide bar through the second sliding groove, and the terminal block can be easily removed from the mounting groove, which is convenient for the inspection of each branch line body. The connecting plate is an elastic steel sheet structure, and the rear end of the first sliding groove passes through the rear end of the plug shell. The end of the slide bar away from the connecting plate is fixed with a stopper. By moving the paddle out of the rear end of the first sliding groove and limiting the slide bar in the second sliding groove through the stopper, the connecting plate can be bent into an arc, so that the terminal blocks on the connecting plate can be spread out separately, and the spacing is increased, which is more conducive to the inspection operation.

[0013] 2. Through the alignment slot on the limiting plate and the plug-in, combined with the blocking angle and the plug shell blocking the limiting plate, it can ensure that the connecting plate is stable in the plug shell when the plug shell is installed, ensuring that the cable harness can work normally.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, the aluminum alloy new energy vehicle cable harness includes a plurality of branch line bodies 1, and the ends of the plurality of branch line bodies 1 are connected through a plug assembly (in order to facilitate the display of the plug assembly, the figure shows the truncated branch line body 1);

[0021] like Figure 1 , Figure 4 As shown, the plug assembly includes a plug shell 2 arranged along the front-to-back direction; an external socket 3 is evenly embedded inside the front end of the plug shell 2; a mounting groove 4 is opened at the rear end of the plug shell 2; a connecting plate 5 is slidably inserted in the mounting groove 4 along the front-to-back direction; the connecting plate 5 is an elastic steel sheet structure; the upper and lower ends of the rear part of the plug shell 2 are both provided with a first slide groove 6 along the front-to-back direction; the first slide groove 6 is connected with the mounting groove 4; the rear end of the first slide groove 6 passes through the rear end of the plug shell 2; the left and right ends of the rear part of the plug shell 2 are both provided with a second slide groove 7 along the front-to-back direction; the second slide groove 7 is connected with the mounting groove 4; paddles 8 are fixed at the upper and lower ends of the connecting plate 5; the connecting plate Slide bars 9 are fixed on both the left and right ends of 5; the paddles 8 slide through the first slide slots 6 one by one; the slide bars 9 slide through the second slide slots 7 one by one; a stopper 10 is fixed on the end of the slide bars 9 away from the connecting plate 5; a plurality of terminal blocks 11 are evenly distributed on the rear side of the connecting plate 5; the terminal blocks 11 are connected to the connecting plate 5 through a detachable module; the rear end of the terminal block 11 is connected to the end of the branch line body 1 one by one; when the paddle 8 abuts against the front end of the first slide slot 6, the front end of the terminal block 11 is connected to the rear end of the external plug sleeve 3 one by one; a limiting component for positioning the paddle 8 at the front end of the first slide slot 6 is provided on the plug housing 2;

[0022] like Figure 1 As shown, the limiting component includes a limiting plate 12 placed on the upper end of the plug shell 2; an alignment slot 13 is opened on the limiting plate 12; the alignment slot 13 is correspondingly plugged with the paddle 8 on the upper end of the connecting plate 5; a blocking angle 14 is fixed to the rear part of the upper end of the plug shell 2; the blocking angle 14 is used to block the rear end and the left and right ends of the connecting plate 5; the front part of the upper end of the plug shell 2 is used to block the front end of the limiting plate 12.

[0023] When the cable harness fails, in the present technical solution, the cable harness is inspected as a whole by unplugging the plug housing 2 from the external connector. When a branch line 1 is faulty, there is no need to replace the entire cable harness, only the faulty branch line 1 needs to be replaced, thereby reducing costs.

[0024] The terminal blocks 11 connected to each branch line body 1 on the traditional cable harness are fixed in the plug housing 2 and cannot be removed, so the branch line body 1 connected to the terminal block 11 is not easy to be removed separately. In the present technical solution, by removing the limiting plate 12, the connecting plate 5 is driven to move toward the rear end of the installation slot 4 by the paddle 8, and the terminal block 11 can be driven out of the installation slot 4 by the connecting plate 5. In addition, the blocking of the stopper 10 on the slide bar 9 by the second slide slot 7 and the elastic bending characteristics of the elastic steel sheet structure of the connecting plate 5 itself can be combined to continue to move the paddle 8 out from the rear end of the first slide slot 6, and bend the connecting plate 5 into an arc shape, such as Figure 2 As shown, the terminal blocks 11 on the connection plate 5 can be spread out separately, and the spacing is increased, which is more conducive to maintenance operations.

[0025] After the faulty branch line body 1 is inspected and repaired, the corresponding terminal block 11 can be removed through the detachable module, and the branch line body 1 can be replaced separately without replacing the entire cable harness, which greatly saves costs.

[0026] like Figure 4 As shown, the detachable module includes a conductive column 15 fixed to the front end of the terminal block 11; the conductive column 15 is threadedly connected to the connecting plate 5; when the paddle 8 abuts against the front end of the first slide groove 6, the front end of the conductive column 15 penetrates and is plugged into the corresponding external socket 3.

[0027] When removing a branch line 1, the conducting column 15 can be removed from the connecting plate 5 by screwing the terminal block 11, which is convenient to operate. The conducting column 15 is inserted into the external socket 3 to ensure that after the external socket 3 is connected to the external connector, each branch line 1 can be connected to the external connector normally, thereby improving the reliability of use.

[0028] like Figure 1 , Figure 3 As shown, the left and right ends of the limiting plate 12 are respectively fixed with extended retaining frames 16; when the alignment slots 13 are correspondingly plugged with the paddles 8, the extended retaining frames 16 correspondingly block the slide bars 9 at the front ends of the second slide slots 7. After the limiting plate 12 limits the paddles 8, the extended retaining frames 16 also limit the slide bars 9, further improving the installation stability of the connecting plate 5.

[0029] like Figure 3-4As shown, a supporting rubber sleeve 17 is inserted into the rear end of the installation slot 4; the supporting rubber sleeve 17 is provided with limiting holes 18; the limiting holes 18 are plugged into the terminal blocks 11 one by one. The supporting rubber sleeve 17 can, on the one hand, play a supporting and limiting role for each terminal block 11, so that when the new energy vehicle is driving, the connection of each terminal block 11 is ensured to be stable; on the other hand, it can also block the internal space of the installation slot 4, effectively prevent dust, and improve the long-term durability of the plug assembly.
