Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model discloses a connection terminal for an automotive wire harness with stability, including a first wire harness end 1. The left side of the first wire harness end 1 is inserted with a second wire harness terminal 2. A sealing mechanism 3 is installed at a position corresponding to the left and right of the second wire harness terminal 2 and the first wire harness end 1. Limiting mechanisms 4 are arranged at the upper and lower positions on the right side of the first wire harness end 1. Rectangular boxes 5 are installed on the limiting mechanisms 4, and the opposite side faces of the upper and lower rectangular boxes 5 are both open structures. The rectangular boxes 5 cover the first wire harness end 1 and the second wire harness terminal 2. Protection mechanisms 6 are arranged on the inner walls of the rectangular boxes 5. First buckling mechanisms 7 are arranged between the left side faces of the rectangular boxes 5 and the second wire harness terminals 2. Second buckling mechanisms 8 are arranged between the front and rear side faces of the rectangular boxes 5, and the second buckling mechanisms 8 connect and fix the upper and lower rectangular boxes 5.

[0021] Specifically, the sealing mechanism 3 includes a retaining ring 301 and a sealing rubber ring 302. The retaining ring 301 is fixedly installed on the outer surface of the second wire harness terminal 2. A sealing rubber ring 302 is fixedly installed on the right side face of the retaining ring 301, and the right side face of the sealing rubber ring 302 is attached to the left side face of the first wire harness end 1.

[0022] In this implementation scheme, the retaining ring 301 is used to fix the sealing rubber ring 302, and the sealing rubber ring 302 makes the sealing effect between the left side face of the first wire harness end 1 and the right side face of the second wire harness terminal 2 better.

[0023] Specifically, the limiting mechanism 4 includes a limiting pin 401 and a long slot 402. Limiting pins 401 are arranged near the front and rear positions on the right side of the rectangular box 5, and long slots 402 are opened on the right side of the rectangular box 5 corresponding to the limiting pins 401. The rectangular box 5 is installed on the limiting pins 401 through the long slots 402.

[0024] In this implementation scheme, the limiting pin 401 is used to limit the rectangular box 5 so that the rectangular box 5 will not detach from the first wire harness end 1. The rectangular box 5 moves up and down along the limiting pin 401 through the long slot 402.

[0025] Specifically, a semi-circular hole 9 is opened at a position corresponding to the first wire harness end 1 on the right side wall of the rectangular box 5, and a rectangular notch 10 is opened at a position corresponding to the second wire harness terminal 2 on the left side wall of the rectangular box 5.

[0026] In this implementation scheme, the semi-circular holes 9 on the right side walls of the upper and lower rectangular boxes 5 are used for the display and passage installation of the first wire harness end 1, and the rectangular notch 10 on the upper rectangular box 5 is used for the passage and installation of the second wire harness terminal 2.

[0027] Specifically, the protection mechanism 6 includes a shielding film 601 and an insulating rubber layer 602. The shielding film 601 and the insulating rubber layer 602 are fixedly pasted on the inner wall of the rectangular box 5 in sequence from the inside to the outside.

[0028] In this implementation scheme, the shielding film 601 and the insulating rubber layer 602 enhance the anti-signal interference and insulation performance between the first wire harness end 1 and the second wire harness terminal 2.

[0029] Specifically, the first snap mechanism 7 includes an elastic block 701 and a snap ring 702. The elastic block 701 is fixedly installed on the upper surface of the second wire harness terminal 2, and a snap ring 702 is installed on the left side surface of the upper rectangular box 5 corresponding to the elastic block 701. The elastic block 701 is snap-fitted into the snap ring 702. The second snap mechanism 8 has the same structure as the first snap mechanism 7.

[0030] In this implementation scheme, the elastic blocks 701 on the upper and lower sides of the second wire harness terminal 2 are snap-fitted into the snap rings 702 on the left side surfaces of the upper and lower rectangular boxes 5 to realize the connection and fixation between the second wire harness terminal 2 and the upper and lower rectangular boxes 5. Similarly, the second snap mechanism 8 snap-connects and fixes the front and rear side surfaces of the upper and lower rectangular boxes 5.

[0031] During use, insert the second wire harness terminal 2 into the first wire harness end 1. At this time, the retaining ring 301 in the sealing mechanism 3 is used to fix the sealing rubber ring 302. The sealing rubber ring 302 makes the sealing effect between the left side surface of the first wire harness end 1 and the right side surface of the second wire harness terminal 2 better, increasing the sealing and waterproof performance between the docking surfaces of the first wire harness end 1 and the second wire harness terminal 2, effectively preventing rainwater from entering and causing a short circuit. Then, fit the opposite side surfaces of the upper and lower rectangular boxes 5 together. During the process of the upper and lower rectangular boxes 5 moving towards each other, the elastic clamping blocks 701 on the upper and lower side surfaces of the second wire harness terminal 2 in the first clamping mechanism 7 are clamped and installed in the clamping rings 702 on the left side surface of the upper and lower rectangular boxes 5, realizing the connection and fixation between the second wire harness terminal 2 and the upper and lower rectangular boxes 5. Similarly, the second clamping mechanism 8 makes the front and rear side surfaces of the upper and lower rectangular boxes 5 clamped and connected and fixed, so that the upper and lower rectangular boxes 5 cover and limit the first wire harness end 1 and the second wire harness terminal 2. The inner walls around the upper and lower rectangular boxes 5 are in contact with the outer surfaces of the first wire harness end 1 and the retaining ring 301, making the connection between the first wire harness end 1 and the second wire harness terminal 2 more stable, not easily detached, and safer to use. Through the shielding film 601 and the insulating rubber layer 602 in the protection mechanism 6 in the upper and lower rectangular boxes 5, the anti-signal interference and insulation performance between the first wire harness end 1 and the second wire harness terminal 2 are increased, ensuring stable information transmission.

[0032] In summary, this stable connection terminal for automotive wire harnesses makes the connection between the first wire harness end 1 and the second wire harness terminal 2 more stable, not easily detached, and safer to use. At the same time, it increases the sealing and waterproof performance between the two, effectively preventing rainwater from entering and causing a short circuit, and increases the anti-signal interference function between the two, ensuring stable information transmission.
