Description

Technical Field

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

[0002] The wire harness connecting sleeve and wire harness connecting structure disclosed in CN221227027U include an insulating sleeve body and an electrical connection part. An annular sealing area is provided on the outer peripheral surface of the insulating sleeve body. The insulating sleeve body includes a first end and a second end, which are respectively disposed on both sides of the annular sealing area. The insulating sleeve body is used for a single wire harness to pass through and to form a sealed fit with the single wire harness. The electrical connection part is used for connecting wire harness terminals, and the electrical connection part is connected to the first end or the second end of the insulating sleeve body.

[0003] It separates the three-phase wires, with one connector sleeve corresponding to one wire harness. The creepage distance is longer and safer compared to the traditional integrated quick-connect connector. At the same time, the outer periphery of the wire harness connector sleeve can form a sealed fit with the housing to prevent oil leakage.

[0004] However, when the phase wire exits from the wire harness connector sleeve, it is affected by the change in the connection position, causing the phase wire to bend. The connector sleeve lacks buffer, resulting in excessive bending and damage to the phase wire. Furthermore, when the phase wires are connected, the connector sleeve at the connection point lacks a connection structure and protection, making disassembly and assembly inconvenient. This solution provides low protection for the phase wire and is inconvenient for disassembly and assembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wire harness connecting sleeve and a wire harness connecting structure, which solves the problems of phase wire bending caused by changes in connection position when exiting the wire harness connecting sleeve, the lack of internal buffering in the connecting sleeve leading to excessive bending and damage of the phase wire, and the lack of a connecting structure and protection at the connection point when the phase wires are connected, resulting in inconvenience in disassembly and assembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire harness connecting sleeve and a wire harness connecting structure, including an L-shaped base, wherein a through hole is provided on the surface of the L-shaped base, and a rubber sleeve for wire harnessing is sleeved inside the through hole, and a connecting component for wire connection protection is provided at one end of the rubber sleeve.

[0007] In a specific embodiment, the connecting assembly includes a first short section disposed at one end of the rubber sleeve, and a second short section is inserted into one end of the first short section. A plurality of first springs are fixedly connected in a circular array on the surface of one end of the first short section, and triangular plates are fixedly connected in an axially symmetrical manner on both sides of the first springs. A positioning plate is movably connected inside the triangular plate, and a triangular block is disposed on one side of one end of the positioning plate. A positioning ring is disposed at one end of the second short section, and the positioning ring is engaged with the surface of the triangular block.

[0008] In one specific embodiment, a positioning sleeve is provided inside one end of the second short section, and the positioning sleeve is made of flexible rubber.

[0009] In one specific embodiment, the rubber sleeve has a cavity inside, and a second spring for cushioning is provided inside the cavity.

[0010] In one specific embodiment, the other end of the rubber sleeve is provided with a conical cap, and the conical cap has a threading hole for threading.

[0011] In one specific embodiment, a positioning hole is provided on one side of the L-shaped base, and a threaded cap for connection and fixing is provided inside the positioning hole.

[0012] Compared with the prior art, the present invention provides a wire harness connecting sleeve and a wire harness connecting structure, which has the following advantages:

[0013] In the technical solution disclosed in this utility model, by utilizing the setting of the connecting component, when the phase wires are connected, one end of the phase wire can be passed through the inside of the rubber sleeve, and the other phase wire can be passed through the inside of the second short section, and the two phase wires can be connected. After the connection is completed, the second short section can be inserted into one end of the first short section. At the same time, the positioning plate and the triangular block on the surface of one end of the first short section are compressed by the positioning ring to compress the first spring until the triangular block hooks the positioning ring, thereby completing the fixation and providing protection for the connection of the phase wires, and improving the convenience of subsequent disassembly and maintenance.

[0014] The rubber sleeve of this invention has an internal cavity, and a second spring for buffering is installed inside the cavity. The second spring can buffer and protect the phase wire from bending, prevent the phase wire from being damaged due to excessive bending, and improve the protection effect of the phase wire.

A through hole 2 is provided on the surface of the L-shaped base 1, and a rubber sleeve 3 for wire harnessing is sleeved inside the through hole 2. A connecting component 4 for wire connection protection is provided at one end of the rubber sleeve 3.

[0023] The specific problem addressed in this embodiment is: when the phase wire exits from the wire harness connecting sleeve, it is affected by changes in the connection position, causing the phase wire to bend. The lack of internal cushioning in the connecting sleeve leads to excessive bending and damage of the phase wire. Furthermore, when the phase wires are connected, the connecting sleeve at the connection point lacks a connection structure and protection, resulting in inconvenience in disassembly and assembly. This utility model utilizes the connecting component 4. When the phase wires are connected, one end of the phase wire can pass through the inside of the rubber sleeve 3, and the other phase wire can pass through the inside of the second short section 42, connecting the two phase wires. After connection, the second short section 42 can be inserted into one end of the first short section 41. Simultaneously, the positioning plate 45 and the triangular block 46 on one end of the first short section 41 are compressed by the positioning ring 421, compressing the first spring 43 until the triangular block 46 hooks onto the positioning ring 421, thus completing the fixation and providing protection at the phase wire connection point, while also improving the convenience of subsequent disassembly and maintenance.

[0024] The second short section 42 has a positioning sleeve inside one end, and the positioning sleeve is made of flexible rubber.

[0025] The connecting component 4 includes a first short section 41 disposed at one end of the rubber sleeve 3, and a second short section 42 inserted into one end of the first short section 41. A plurality of first springs 43 are fixedly connected in a circular array on the surface of one end of the first short section 41, and triangular plates 44 are fixedly connected symmetrically on both sides of the first springs 43. A positioning plate 45 is movably connected inside the triangular plate 44, and a triangular block 46 is disposed on one side of one end of the positioning plate 45. A positioning ring 421 is disposed at one end of the second short section 42, and the positioning ring 421 engages with the surface of the triangular block 46. In this specific embodiment, a cavity 5 is formed inside the rubber sleeve 3, and a second spring 6 for buffering is disposed inside the cavity 5. The second spring 6 can buffer and protect the phase wire from bending, preventing excessive bending and damage to the phase wire, and improving the protection effect of the phase wire.

[0026] In this specific embodiment, a conical cap 7 is provided at the other end of the rubber sleeve 3, and a threading hole for threading is provided inside the conical cap 7. A positioning hole is provided on one side of the L base 1, and a threaded cap for connection and fixing is provided inside the positioning hole.
