[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Example 1, reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a tensile-resistant wiring harness connector that is easy to install and can prevent the cable 14 from being pulled. It includes a first connector 10, a second connector 11 is provided on the outside of the first connector 10, an elastic block 12 is provided on the first connector 10, and a limiting opening 13 that cooperates with the elastic block 12 is provided on the second connector 11. A plurality of cables 14 are provided on the first connector 10 and the second connector 11; an installation box 20 on the first connector 10 and the second connector 11, a U-shaped plate 21 is fixedly connected to the installation box 20, and the U-shaped plate 21 is fixedly connected to the installation box 20. A guide portion 22 for supporting the cable 14 is provided on the U-shaped plate 21, an elastic portion 23 for moving the guide portion 22 is provided on the U-shaped plate 21, a plurality of through-holes 24 are provided on the installation box 20, a display portion 25 for reflecting the degree to which the cable 14 is pulled is provided in the plurality of through-holes 24, and the U-shaped plate 21 is provided with a bearing portion 26 for cooperating with the display portion 25; a plurality of bayonet holes 30 are provided on the second connector 11, an extension portion 31 for cooperating with the bayonet hole 30 is provided in the display portion 25, and a receiving groove 32 connected to the bayonet hole 30 is provided on the second connector 11, and a protrusion portion 33 and a pressing portion 34 for resetting the extension portion 31 are provided in the receiving groove 32.

[0027] Specifically, when the elastic block 12 on the first connector 10 cooperates with the limit opening 13, the first connector 10 and the second connector 11 can be installed. Here, the outer ends of multiple cables 14 can be connected to new connectors or grounded, thereby achieving a grounding effect and protecting the safety of the entire circuit. This is the existing technology and will not be elaborated here. An insulating sleeve is also provided on the outer wall of the cable 14 to resist electromagnetic interference.

[0028] Furthermore, the guide portion 22 includes a guide opening 221 provided on the U-shaped plate 21 for the cable 14 to pass through, the guide opening 221 passes through the installation box 20, and a locking ring 222 is fixedly connected to the cable 14, the locking ring 222 is abutted against the bottom side wall of the U-shaped plate 21, and a semicircular ring 223 is provided in the U-shaped plate 21 for allowing the cable 14 to bend; the elastic portion 23 includes a slide plate 231 slidably connected to the U-shaped plate 21, the inner wall of the U-shaped plate 21 is provided with a guide groove 232, and a guide block matching the guide groove 232 is fixedly connected to the slide plate 231, and a square opening 233 passing through the U-shaped plate 21 and the installation box 20 is provided on the slide plate 231, and a push plate 234 is slidably connected in the square opening 233, and the push plate 234 is fixedly connected to the semicircular ring 223, and the slide plate 231 is elastically connected to the inner wall of the U-shaped plate 21 through a first spring 235.

[0029] Among them, the locking ring 222 here is against the bottom side wall of the U-shaped plate 21. When the cable 14 is pulled, the locking ring 222 is against the side wall of the U-shaped plate 21, preventing the cable 14 close to the first connector 10 from being pulled, thereby ensuring the stability of the connection between the first connector 10 and the cable 14. The setting of the semicircular ring 223 can push the middle part of the cable 14 to arch, so that a section of the cable 14 will remain in the installation box 20 to cope with the influence of thermal expansion and contraction on the cable 14, and further prevent the connection of the cable 14 from being pulled.

[0030] Preferably, the display portion 25 is provided on a display board 251 in the through-opening 24, and multiple display boards 251 are provided along the through-opening 24. A pair of support plates and a pair of carrying plates 252 are fixedly connected to the multiple display boards 251. The support plate on the right-end display board 251 is rotatably connected to the carrying plate 252 on the left-end support board through a rotating shaft 253, and the rotating shaft 253 is provided with a torsion spring 254; stickers 255 are provided on the side walls of the multiple display boards 251, and the colors of the multiple stickers 255 are different; an interlayer 256 is provided in the multiple display boards 251, and the interlayer 256 is filled with fluorescent powder. Transparent acrylic plates 257 are provided at the front and rear ends of the interlayer 256; the carrying portion 26 includes a strip opening 261 provided on the U-shaped plate 21, the strip opening 261 passes through the installation box 20, and a strip plate 262 cooperating with the display board 251 is slidably connected in the strip opening 261.

[0031] It should be noted that the strip plate 262 supports the display board 251, which can avoid the problem that the display board 251 cannot be moved due to the automatic deflection of the torsion spring 254 in the installation box 20. The setting of the sticker 255 can show the degree of pulling of the cable 14 according to different colors, thereby avoiding excessive pulling of the cable 14.

[0032] When in use, first allow the first connector 10 to be plugged into the second connector 11. After the plugging is completed, the elastic block 12 of the first connector 10 cooperates with the limit opening 13 to install the first connector 10 and the second connector 11. At this time, the cable 14 is supported by the semicircular ring 223, and the cable 14 in the U-shaped plate 21 is bent, so that a certain length is provided to cope with the influence of thermal expansion and contraction on the connection of the cable 14. Then, the end of the cable 14 is connected, and the cable 14 is pulled. After the cable 14 is pulled through During the process, the cable 14 slowly becomes vertical. At this time, the cable 14 exerts an extrusion force on the semicircular ring 223, driving the ring to move toward the through-opening 24, that is, toward the rear end of the installation box 20. When the semicircular ring 223 moves, it can drive the push plate 234 to move toward the through-opening 24, so that the display plate 251 is pushed out of the through-opening 24. During the process of the display plate 251 being pushed out, the display plate 251 and the strip plate 262 are against each other. At this time, the torsion spring 254 obtains elasticity. When a display plate 251 is pushed out, the display plate 251 and the strip plate 262 are pressed against each other. At this time, the torsion spring 254 obtains elasticity. After being fully pushed out, the display board 251 flips under the action of the torsional force, causing the display board 251 to fit against the rear wall of the installation box 20, thereby preventing the display board 251 from extending and colliding with other items. At the same time, after the display board 251 is flipped, the extent of the cable 14 being pulled can be determined by simply observing the color of the display board 251. Based on the color of the display board 251, it is determined whether the cable 14 should continue to be pulled, ensuring that sufficient length is reserved to cope with the effects of thermal expansion and contraction on the cable 14 connection. The provision of fluorescent powder here allows the color of the display board 251 to be observed through the acrylic plate 257 at night, without affecting the observation of the display board 251 due to dim light or darkness. It should be noted that in actual use, a mounting box 20 (not shown here) is provided on the second connector 11 to resist the pulling of the cable 14 on the second connector 11. At the same time, when the strip plate 262 moves, it will not pass through the mounting box 20, thereby not affecting the flipping of the display board 251.

[0033] In summary, by providing a tensile component, when the cable 14 is pulled, the semicircular ring 223 can be driven to move, so that the display board 251 moves to the outside of the installation box 20. The degree to which the cable 14 is pulled can be judged according to the color of the sticker 255 on the side wall of the display board 251. Therefore, when the cable 14 is installed, it is stopped in time when it is pulled to a certain extent, ensuring that there is sufficient reserved length to cope with the influence of thermal expansion and contraction on the pulling of the cable 14 connection. At the same time, the setting of the locking ring 222 can prevent the cable 14 connection from being pulled, so that the connection between the cable 14 and the first connector 10 is more stable.

[0034] Example 2, reference Figures 1 to 6 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a tensile-resistant wiring harness connector that is easy to install, and solves the problem of how to separate the first connector 10 and the second connector 11 when the cable 14 is pulled. It includes an extension portion 31, including a T-shaped slot 311 arranged in the outermost display plate 251, and a T-shaped block 312 that cooperates with the bayonet 30 is slidably connected in the T-shaped slot 311. The T-shaped block 312 is elastically connected to the inner wall of the T-shaped slot 311 by a second spring 313. The second connector 11 and the T-shaped block 312 are both provided with a bevel 314.

[0035] Specifically, the T-shaped block 312 cooperates with the bayonet 30 to limit the T-shaped slot 311, thereby preventing the first connector 10 and the second connector 11 from being separated. The bevel 314 here can prevent the T-shaped block 312 and the bayonet 30 from getting stuck.

[0036] During use, after the multiple display plates 251 extend out of the through-hole 24, the length of the multiple display plates 251 after flipping over also becomes longer. The elasticity of the torsion spring 254 here is greater than the elasticity of the second spring 313. Therefore, after the display plates 251 are flipped over, the second spring 313 is compressed. When the semicircular ring 223 reaches a certain position (this position is not fixed, it can be a position where the push plate 234 cannot move, or it can be a corresponding position when the cable 14 is straightened, and it is set as needed), the T-shaped block 312 is aligned with the bayonet 30 on the second connector 11. Under the action of the second spring 313, the T-shaped block 312 moves into the bayonet 30, strengthening the connection between the first connector 10 and the second connector 11, and preventing the first connector 10 and the second connector 11 from loosening due to the pulling of the cable 14.

[0037] In summary, by providing a reinforcing component, after the display board 251 is flipped over, the T-shaped block 312 can be inserted into the bayonet 30 to reinforce the connection between the first connector 10 and the second connector 11, thereby preventing the first connector 10 and the second connector 11 from loosening due to the cable 14 being pulled.

[0038] Example 3, reference Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a tensile-resistant wiring harness connector that is easy to install and solves the problem of how to conveniently disassemble the first connector 10 and the second connector 11. It includes a protruding portion 33, including a horizontal plate 331 arranged in a sliding connection with the accommodating groove 32, and a top block 332 that cooperates with the card block is provided on the horizontal plate 331; a pressing portion 34, including a communicating port 341 arranged in the accommodating groove 32, a T-shaped pressing block 342 is slidably connected in the accommodating groove 32, and the pressing block 342 and the horizontal plate 331 are provided with mutually cooperating inclined surfaces 343, and the horizontal plate 331 is elastically connected to the inner wall of the accommodating groove 32 by a third spring 344.

[0039] Specifically, the push block 332 cooperates with the T-shaped block 312 to push the T-shaped block 312 out of the bayonet 30 to facilitate disassembly between the first connector 10 and the second connector 11. The pressing block 342 and the inclined surface 343 provided on the cross plate 331 prevent the pressing block 342 from getting stuck with the cross plate 331. The pressing block 342 is T-shaped, which can prevent the pressing block 342 from detaching from the accommodating groove 32. A plurality of push blocks 332 are provided here, so that a plurality of T-shaped blocks 312 can be ejected.

[0040] During use, when multiple T-shaped blocks 312 need to be ejected, it is only necessary to squeeze the pressing block 342 so that the pressing block 342 moves and drives the horizontal plate 331 to move, so that the ejecting block 332 enters the bayonet 30 and ejects the T-shaped block 312, and then move the elastic card block 12 to disassemble the first connector 10 and the second connector 11.

[0041] In summary, by providing the ejection portion 33 and the pressing portion 34, when disassembling the first connector 10 and the second connector 11, it is only necessary to squeeze the pressing block 342 to disengage the T-shaped block 312 from the bayonet 30, and then to move the elastic card block 12 to complete the disassembly between the first connector 10 and the second connector 11, making the disassembly of the first connector 10 and the second connector 11 more convenient.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
