Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, and in particular to a cable harness connector that is easy to assemble and disassemble. Background Technology

[0002] Wire harness connectors, also known as wire harness plugs, are a type of terminal. Connectors, also called plugs, consist of a plug and a socket. Most existing wire harness connectors use interference-fit or threaded rotary connections, which are inconvenient to operate and prone to jamming.

[0003] The technical solution disclosed in Chinese Patent No. CN220510284U involves setting a rotatable sleeve on the first terminal, with an "L"-shaped slot on the inner wall of the sleeve. A locking block adapted to the slot is set on the second terminal. In use, the second terminal is inserted into the first terminal, and the locking block can be inserted into the slot. After the sleeve is rotated in a certain direction, it forms a locking and limiting structure, completing the insertion control between the first and second terminals, which is convenient for quick connection. When disassembly is required, the sleeve is rotated in the opposite direction, so that the locking block loses its constraint control, and the second terminal can be easily separated from the first terminal. Thus, the effect of quick and convenient disassembly and assembly is achieved while protecting the terminal pin structure.

[0004] However, the device still has shortcomings: the conductor and cable lack a detachable structure, which is not conducive to subsequent installation or replacement. In addition, the device uses a rotating snap-fit ​​connection, which can easily cause the structure to rotate automatically when the cable vibrates with the load mechanical equipment, thus causing the joint to separate.

[0027] Example 1

[0028] like Figures 1-6As shown, this utility model proposes a conveniently assembled and disassembled wire harness connector, including a female plug 1, a main cable 4, a retainer 5, a male plug 6, a branch cable 9, a pin 10, and a locking assembly 12. The female plug 1 is provided with a first limiting groove 101, within which a first battery cell 2 slides along its inner diameter. The first battery cell 2 is provided with several power connection holes 201 and several first wire clamping assemblies 3. Each first wire clamping assembly 3 includes a first countersunk screw and a first voltage-conducting plate. Several non-cylindrical main wire core insertion holes are provided on the end face of the first battery cell 2, and several first countersunk holes 202 are provided on the arc surface of the first battery cell 2. Each first voltage-conducting plate is located within the corresponding main wire core insertion hole and is slidably connected to its inner wall. The first countersunk screw is located within the first countersunk hole 202 and is rotatably connected to the first battery cell 2. The first countersunk screw is spirally connected to the first voltage-conducting plate. One end of the main cable 4 is inserted into the female connector 1, and each main core of the main cable 4 is inserted into the corresponding main core socket. A retainer 5 is connected to the female connector 1, and the retainer 5 has a retaining hole 51 communicating with its inner cavity. A second limiting groove 61 is provided on the male connector 6, and a second battery core 7 is provided within the second limiting groove 61, sliding radially therein. The second battery core 7 has several connecting rods 71, is electrically connected to the first battery core 2, and has several second wire clamping assemblies 8. The second wire clamping assembly 8 includes a second countersunk screw and a second conductive plate. Several non-cylindrical branch core sockets are provided on the end face of the second battery core 7, and several second countersunk holes 72 are provided on the arc surface of the second battery core 7. Each second conductive plate is located within the corresponding branch core socket and is slidably connected to its inner wall. The second countersunk screw is located within the second countersunk hole 72 and is rotatably connected to the second battery core 7. The second countersunk screw is screwed to the second conductive plate. One end of the branch cable 9 is inserted into the male connector 6, and each branch core of the branch cable 9 is inserted into the corresponding branch core socket. The pin 10 is connected to the male connector 6, and a spring rod is provided inside the pin 10. The movable end of the spring rod is connected to the wedge-shaped locking block 11. When the pin 10 is inserted into the locking sleeve 5, the wedge-shaped locking block 11 pops out and locks into the locking hole 51. One set of locking components 12 is connected to the female connector 1, and the other set of locking components 12 is connected to the male connector 6. The locking components 12 include a connecting tube 121. The two connecting tubes 121 are integrally connected to the female connector 1 and the male connector 6, respectively. A knob 122 is screwed onto the connecting tube 121 and is connected to it. The knob 122 is connected to a movable sleeve 124. The movable sleeve 124 has a groove with an inner diameter the same as the outer diameter of the connecting tube 121, and a wire hole coaxial with the groove is provided on the movable sleeve 124. The inner diameter of the wire hole is the same as the inner diameter of the connecting tube 121. The second sealing ring 126 is disposed in the slide groove and coaxial with it, and the two ends of the second sealing ring 126 abut against the inner wall of the slide groove and the end face of the connecting pipe 121, respectively.

[0029] In this embodiment, after the cable is damaged, the knob 122 is first loosened. At this time, the inner diameter of the second sealing ring 126 gradually increases, thereby releasing the locking state of the cable. Then, the cable is pushed to push out the first battery cell 2 or the second battery cell 7. The countersunk screw of the knob loosens the conductive plate, and the wire core of the cable is in a movable state. At this time, the cable can be directly separated from the battery core. After replacing the cable, the battery core is re-inserted into the female plug 1 or the male plug 6, and the knob 122 is tightened. The knob 122, together with the end face of the connecting tube 121, squeezes the second sealing ring 126, thereby using the second sealing ring 126 to deform inward and squeeze and lock the cable. The second sealing ring 126 fills the gap between the cable sheath and the interactive sleeve 124, effectively playing the role of waterproofing, dustproofing and leakage prevention. When connecting the female plug 1 and the male plug 6, align the power connection rod 71 on the second battery cell 7 with the power connection hole 201 on the first battery cell 2 and gradually insert it into place. At this time, the pin 10 is inserted into the inner cavity of the sleeve 5. After the male plug 6 and the female plug 1 are connected in place, the wedge-shaped locking block 11 automatically pops out and locks the two together. When it is necessary to separate them, simply press the wedge-shaped locking block 11 to make it retract, and then pull the male plug 6 or the female plug 1 horizontally to separate the two.

[0030] Example 2

[0031] like Figure 6 As shown, the present invention proposes a conveniently assembled and disassembled wire harness connector. Compared with Embodiment 1, the knob 122 is coaxially connected to the slip ring 123, and the movable sleeve 124 is provided with a second annular groove 125. The slip ring 123 is inserted into the second annular groove 125 and slidably connected to its inner wall. A third annular groove is provided on the arc surface of the second sealing ring 126, which is coaxial with it, and the inner diameter of the second sealing ring 126 is the same as the inner diameter of the wire hole.

[0032] In this embodiment, the movable sleeve 124 is coaxially rotatably connected to the knob 122, which avoids the second sealing ring 126 from rubbing against the cable sheath and causing wear after the second sealing ring 126 comes into contact with the cable and the knob 122 is turned. This effectively improves the service life of the second sealing ring 126. In addition, this structure can avoid excessive direct friction between the second sealing ring 126 and the cable surface, which would make it more difficult to rotate the knob 122.

[0033] Example 3

[0034] like Figure 2 and Figure 4 As shown, the present invention proposes a conveniently assembled and disassembled wire harness connector. Compared with Embodiment 1, the female connector 1 is provided with a first annular groove 102, and a first limiting groove 101 is located inside the first annular groove 102. The male connector 6 is provided with a first sealing ring 62, which is inserted into the first annular groove 102 and slidably connected to its inner wall.

[0035] In this embodiment, with the female plug 1 and male plug 6 locked, the first sealing ring 62 and the first annular groove 102 work together to effectively prevent dust and water from entering the first battery cell 2 and the second battery cell 7.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
