Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically to a wire harness with a sealed structure. Background Technology

[0002] Currently, waterproof products require wiring holes to be made in the outer casing. When encountering rainy weather, the outer casing is easily penetrated by rainwater, causing short circuits in the wires inside the waterproof product. Therefore, most waterproof products now require waterproofing measures to prevent rainwater from seeping into them when wiring.

[0003] A search revealed that, for example, patent CN212137249U discloses a wire harness technology patent, which discloses a wire harness with a sealing structure, including a wire harness body and a sealing structure. The sealing structure includes a column and an elastic filler sleeve. One end of the column is integrally formed with an upper end cap, which has a slot. The column has a through hole through which the wire harness body passes. A rigid sleeve is fixed to the inner wall of the through hole, and the inner wall of the sleeve has an annular gap with the outer circumferential surface of the wire harness body. The filler sleeve is located within the gap, and the outer wall of the filler sleeve is threadedly connected to the sleeve. The inner wall of the filler sleeve is tightly fitted to the outer circumferential surface of the wire harness body. This patent uses a threaded connection to seal the wire harness, but under dynamic conditions, the threaded connection may gradually loosen, thus affecting the sealing performance and the stability of the wire harness. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a wire harness with a sealed structure.

[0005] The technical solution of this utility model is implemented as follows: A wire harness with a sealed structure includes a column and a wire harness body. One end of the column is fixedly connected to an upper end cap, and the other end of the column is fixedly connected to a connecting shell. A movable block is sleeved on the outside of the wire harness body. A sealing sleeve is provided inside the movable block. A fixing claw is fixedly connected inside the movable block. A protrusion is provided on the outside of the movable block. A ball is movably connected to the protrusion. A second push block is slidably connected inside the protrusion. A fixing block is fixedly connected to one end of the second push block. A first push block is fixedly connected inside the fixing block. A sliding groove is opened inside the column and the connecting shell. A circular groove is opened inside the sliding groove on the column. A sealing gasket is provided at one end of the connecting shell. A support block is fixedly connected to one end of the movable block.

[0006] Preferably, the upper end cap has a slot on its outside, and a silicone sealing ring is provided inside the slot on the upper end cap, and the upper end cap is elastic.

[0007] Preferably, the fixing claw is elastic, and the thickness of the end of the first push block away from the fixing block is greater than that of the end near the fixing block.

[0008] Preferably, the end of the second pusher corresponding to the ball is an inclined surface, and the circular groove on the cylinder fits snugly with the ball.

[0009] Preferably, one end of the connecting shell has a groove, a connecting block is fixedly connected to one side of the fixing block, a square hole is opened at the top of the connecting block, an annular plate is slidably connected inside the connecting shell, a locking block is fixedly connected inside the annular plate, a connecting seat is fixedly connected inside the connecting shell and the annular plate, and a spring is provided inside the connecting seat.

[0010] Preferably, the end of the card block near the connecting block is a slope.

[0011] Preferably, the annular plate has anti-slip grooves on its outer surface.

[0012] This utility model has the following beneficial effects:

[0013] 1. This wire harness with a sealing structure works by inserting a protrusion on a movable block into a groove on a connecting shell, aligning the ball bearings on the protrusion with the circular groove on the column. Then, pushing a fixed block causes a second pusher block to slide within the protrusion. The inclined surface of the second pusher block pushes the ball bearings to move, causing some of the ball bearings to extend out of the movable block and fit against the circular groove on the column, thus fixing the movable block to the column. Simultaneously, the fixed block causes a first pusher block to insert between the movable block and the fixed claw. The first pusher block then pushes the fixed claw to compress the sealing sleeve, causing the sealing sleeve to fit tightly against the wire harness body and fixing the wire harness body in place. This allows for quick sealing of the wire harness, avoiding the use of threaded connection structures to prevent loosening of the wire harness, thereby ensuring sealing performance and wire harness stability.

[0014] 2. This wire harness with a sealed structure uses a fixing block to drive a connecting block into a groove on the connecting shell. The connecting block then contacts the inclined surface of the locking block, and the connecting block pushes the locking block to move through the inclined surface. The locking block then drives the annular plate to slide on the connecting shell. The annular plate compresses the spring through the connecting seat. When the square hole on the connecting block moves to the locking block area, the spring pushes the annular plate and the locking block back to their original positions, and the locking block inserts into the square hole on the connecting block, thus fixing the fixing block to the connecting shell. If the wire harness body is damaged and needs to be replaced, the annular plate is rotated, which allows the locking block to leave the square hole on the connecting block. The fixing block can then move away, the second push block stops pushing the ball, the moving block can leave the column, and the wire harness body can be pulled out from the moving block. This facilitates the replacement of the wire harness. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, the wire harness with a sealed structure provided in this embodiment includes a column 1 and a wire harness body 6. One end of the column 1 is fixedly connected to an upper end cap 2, and the other end of the column 1 is fixedly connected to a connecting shell 4. A movable block 7 is sleeved on the outside of the wire harness body 6. A sealing sleeve 8 is provided inside the movable block 7. A fixing claw 9 is fixedly connected inside the movable block 7. A protrusion 24 is provided on the outside of the movable block 7. A ball bearing 10 is movably connected to the protrusion 24. A second push block 13 is slidably connected inside the protrusion 24. A fixing block 11 is fixedly connected to one end of the second push block 13. A first push block 12 is fixedly connected inside the fixing block 11. A sliding groove 17 is opened inside the column 1 and the connecting shell 4. A circular groove 18 is opened inside the sliding groove 17 on the column 1. A sealing gasket 16 is provided at one end of the connecting shell 4. A support block 23 is fixedly connected to one end of the movable block 7.

[0024] Furthermore, the upper end cap 2 has a slot 3 on its outside, and a silicone sealing ring is provided inside the slot 3 of the upper end cap 2, making the upper end cap 2 elastic.

[0025] By adopting the above technical solution, the upper end cap 2 is inserted into the thread hole of the waterproof product, and the slot 3 on the upper end cap 2 matches the thread hole of the waterproof product, so that the column 1 is installed on the waterproof product. The silicone sealing ring in the slot 3 on the upper end cap 2 can prevent rainwater from seeping in.

[0026] Furthermore, the fixing claw 9 is elastic, and the thickness of the end of the first push block 12 away from the fixing block 11 is greater than that of the end near the fixing block 11.

[0027] By adopting the above technical solution, the first push block 12 is inserted between the moving block 7 and the fixed claw 9 by the fixed block 11. The first push block 12 then pushes the fixed claw 9 to squeeze the sealing sleeve 8, so that the sealing sleeve 8 is tightly attached to the wire harness body 6.

[0028] Furthermore, the second pusher 13 has an inclined surface at one end corresponding to the ball 10, and the circular groove 18 on the cylinder 1 fits snugly with the ball 10.

[0029] By adopting the above technical solution, the ball bearing 10 is pushed to move by the inclined surface of the second pusher 13, and part of the ball bearing 10 extends out of the moving block 7. The extended part of the ball bearing 10 fits into the circular groove 18 on the column body 1, thereby fixing the moving block 7 on the column body 1.

[0030] Furthermore, a groove 19 is provided at one end of the connecting shell 4, a connecting block 14 is fixedly connected to one side of the fixing block 11, a square hole 15 is provided at the top of the connecting block 14, an annular plate 5 is slidably connected inside the connecting shell 4, a locking block 20 is fixedly connected inside the annular plate 5, a connecting seat 21 is fixedly connected inside the connecting shell 4 and the annular plate 5, and a spring 22 is provided inside the connecting seat 21.

[0031] Furthermore, the end of the card block 20 near the connecting block 14 is a slope.

[0032] By adopting the above technical solution, the connecting block 14 contacts the inclined surface of the locking block 20, and the connecting block 14 can push the locking block 20 to move through the inclined surface of the locking block 20.

[0033] Furthermore, the annular plate 5 has anti-slip grooves 17 on its outer surface.

[0034] By adopting the above technical solution, the friction is increased by the anti-slip groove 17 on the annular plate 5, so that the annular plate 5 can be rotated conveniently.

[0035] Working principle: Insert the upper end cap 2 into the thread hole of the waterproof product. The slot 3 on the upper end cap 2 mates with the thread hole of the waterproof product, thus installing the column 1 onto the waterproof product. Next, insert the support block 23 on the movable block 7 into the connecting shell 4, and then insert the protrusion 24 on the movable block 7 into the sliding groove 17 on the connecting shell 4. After it is fully inserted, the ball bearing 10 on the protrusion 24 aligns with the circular groove 18 on the column 1, while the support block 23 also abuts against the upper end cap 2 from the inside, preventing the upper end cap 2 from deforming inward. Then, push... When the fixed block 11 is moved, it causes the second push block 13 to slide within the protrusion 24. The inclined surface of the second push block 13 then pushes the ball bearing 10 to move, causing part of the ball bearing 10 to extend out of the moving block 7. The extended part of the ball bearing 10 then fits into the circular groove 18 on the column body 1, thus fixing the moving block 7 onto the column body 1. At the same time, the fixed block 11 causes the first push block 12 to insert between the moving block 7 and the fixing claw 9. The first push block 12 then pushes the fixing claw 9 to squeeze the sealing sleeve 8, causing the sealing sleeve 8 to fit tightly against the wire harness body 6 and secure the wire harness. The main body 6 is fixed in place. When the fixing block 11 moves, the fixing block 11 also drives the connecting block 14 to insert into the groove 19 on the connecting shell 4. The connecting block 14 then contacts the inclined surface of the locking block 20. The connecting block 14 pushes the locking block 20 to move through the inclined surface of the locking block 20. The locking block 20 then drives the annular plate 5 to slide on the connecting shell 4. The annular plate 5 then compresses the spring 22 through the connecting seat 21. When the square hole 15 on the connecting block 14 moves to the area of ​​the locking block 20, the spring 22 pushes the annular plate 5 and the locking block 20 to reset. The locking block 20 is inserted into the square hole 15 on the connecting block 14, which fixes the fixing block 11 on the connecting shell 4. At the same time, the sealing gasket 16 between the connecting shell 4 and the fixing block 11 is also squeezed by the fixing block 11. If the wire harness body 6 is damaged and needs to be replaced, simply rotate the annular plate 5 to make the locking block 20 leave the square hole 15 on the connecting block 14, and the fixing block 11 can be moved away. The second push block 13 will no longer push the ball 10, and the moving block 7 can leave the column 1. The wire harness body 6 can then be pulled out from the moving block 7.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
