Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to a wiring harness connector terminal plugging device used in automobile wiring harness production. Background Art

They are key components of electrical connections, connecting the wires in the wiring harness to the electronic system of the car. Existing connectors generally use a snap-on structure, but with the popularity of new energy vehicles, the design requirements for wiring harness connectors are getting higher and higher.

[0003] The Chinese patent discloses "an automotive wiring harness connector" with application number 202321229399.1, which includes a plug, a socket and a connecting wire, as well as a sealing structure and a dustproof structure.

DETAILED DESCRIPTION

[0030] See also Figures 1 to 8 The present invention provides a technical solution: a wiring harness connector terminal plug-in device for automobile wiring harness production, comprising a male terminal 1 and a female terminal 3, and a fourth round rod 14 symmetrically arranged inside the male terminal 1, and also comprising:

[0031] The locking mechanism includes a second rotating rod 27 and a second tension spring 29 symmetrically mounted on the inner wall of the female terminal 3. A one-way gear 26 is mounted on the second rotating rod 27 away from the female terminal 3. A sixth round rod 31 fixedly connected to the second tension spring 29 is mounted on the inner wall of the second rotating rod 27. The second tension spring 29 contracts and drives the second rotating rod 27 to rotate through the sixth round rod 31, and the second rotating rod 27 drives the one-way gear 26 to abut against the outer wall of the fourth round rod 14.

[0032] The clamping mechanism includes a conical block 11 and two rollers 24. The conical block 11 is arranged above the fourth round rod 14. The first slide bars 19 are symmetrically rotatably installed on both sides of the roller 24. The first slide bar 19 has an inclined surface 20 on the side away from the roller 24. A first groove 101 is opened at the inner wall of the male terminal 1 corresponding to the inclined surface 20. The inner wall of the first groove 101 is rotatably installed with a first round rod 102 abutting against the lower side of the inclined surface 20. When the conical block 11 squeezes the roller 24, the roller 24 drives the inclined surface 20 to squeeze the first round rod 102 through the first slide bar 19, so that the first round rod 102 drives the male terminal 1 to descend.

[0033] Further, such as Figure 3 As shown, the third round rod 13 is installed on the upper end surface of the fourth round rod 14, the second round rod 9 is installed on the upper end surface of the third round rod 13, the outer wall of the third round rod 13 is sleeved with a first tension spring 12, the two ends of the first tension spring 12 are respectively installed on the fourth round rod 14 and the conical block 11, the conical block 11 is slidably installed on the second round rod 9, and the upper end surface of the second round rod 9 is installed on the male terminal 1;

[0034] Further, such as Figure 3 and Figure 4 As shown, a spring telescopic rod 10 is symmetrically installed on the upper end surface of the conical block 11, and a sealing cover 15 is installed on the upper end surface of the spring telescopic rod 10 through the male terminal 1. A third groove 17 is opened on the upper end surface of the sealing cover 15, and a pull ring 16 is rotatably installed on the inner wall of the third groove 17. A second groove 8 is opened on the upper end surface of the male terminal 1 corresponding to the sealing cover 15;

[0035] When the spring telescopic rod 10 contracts, it drives the sealing cover 15 to close the second groove 8 to prevent water and dust from entering;

[0036] Pulling the pull ring 16 can drive the spring telescopic rod 10 to rise, and the spring telescopic rod 10 drives the conical block 11 to rise;

[0037] Further, such as Figures 6 to 8 As shown, a first fixing block 28 is rotatably mounted on the outer wall of the second rotating rod 27, and the lower end surface of the first fixing block 28 is mounted on the female terminal 3. A stopper 30 is abutted on one side of the second rotating rod 27, and the lower end surface of the stopper 30 is mounted on the female terminal 3. The second tension spring 29 is mounted on the female terminal 3 away from the sixth round rod 31.

[0038] When the second rotating rod 27 rotates, it rotates with the first fixed block 28 as the center, and the stopper 30 limits the second rotating rod 27;

[0039] Further, such as Figure 6 and Figure 7 As shown, a partition 6 is symmetrically installed on the upper end surface of the female terminal 3, dividing the female terminal 3 into three cavities, a plurality of power transmission sleeves 5 are installed in the middle cavity, and second slide bars 21 are symmetrically slidably installed in the cavities on both sides, and the lower end surface of the second slide bar 21 is installed on the first slide bar 19;

[0040] When the first slide bar 19 moves, it drives the second slide bar 21 to slide on the partition 6 and the inner wall of the female terminal 3;

[0041] Further, such as Figure 2 As shown, a conductive column 7 is installed at the inner wall of the male terminal 1 corresponding to the power transmission sleeve 5, and a wire 2 is installed on the outer walls of the male terminal 1 and the female terminal 3;

[0042] The conductor 2 is connected to the conductive column 7 through the conductive sleeve 5;

[0043] Further, such as Figure 6 As shown, the outer wall of the female terminal 3 is sleeved with a sealing gasket 4, and a through hole 18 is opened at the outer wall of the female terminal 3 corresponding to the first sliding rod 19;

[0044] The sealing gasket 4 keeps the male terminal 1 and the female terminal 3 sealed;

[0045] Further, such as Figure 7 and Figure 8 As shown, the first rotating rod 23 is symmetrically mounted on the outer wall of the first sliding rod 19, a sliding groove 25 is provided on the outer wall of the first rotating rod 23, the outer wall of the first rotating rod 23 abuts against the sixth round rod 31, and the inner wall of the sliding groove 25 is slidably mounted with a fifth round rod 22, and the two ends of the fifth round rod 22 are respectively mounted on the female terminal 3 and the partition 6;

[0046] When the first sliding rod 19 moves, it drives the first rotating rod 23 to move, and the first rotating rod 23 drives the slide groove 25 to move on the sixth round rod 31 and rotate with the sixth round rod 31 as the center of the circle;

[0047] Further, such as Figure 8 As shown, a second fixing block 32 is installed on the inner wall of the first slide bar 19, a spring 33 is installed on the outer wall of the second fixing block 32, and the spring 33 is installed on the inner wall of the female terminal 3 away from the second fixing block 32;

[0048] The spring 33 drives the first slide bar 19 to return to its original position through the second fixing block 32;

[0049] Furthermore, the elastic coefficient of the spring 33 is greater than that of the second tension spring 29, and the elastic coefficient of the first tension spring 12 is greater than that of the spring telescopic rod 10 and the spring 33;

[0050] Furthermore, the overall length of the fourth round rod 14, the third round rod 13 and the second round rod 9 is smaller than the distance between the male terminal 1 and the female terminal 3, and the length of the power transmission sleeve 5 and the conductive column 7 is smaller than the distance between the male terminal 1 and the female terminal 3; they will not prevent the male terminal 1 and the female terminal 3 from approaching each other.

[0051] Working principle: Step 1: Align the male terminal 1 with the female terminal 3, and then press them together. At this time, the conductive column 7 is inserted into the power transmission sleeve 5. As the male terminal 1 descends, the conical block 11 is driven to descend. When the conical block 11 abuts against the outer wall of the roller 24, the roller 24 drives the second slide bar 21 to move away from the conical block 11 through the first slide bar 19. The first slide bar 19 compresses the spring 33 through the second fixed block 32. At the same time, the inclined surface 20 of the first slide bar 19 will penetrate the through hole 18 and abut against the inner wall of the male terminal 1. At this time, the roller 24 will no longer move, and the conical block 11 will stretch the first tension spring 12;

[0052] Step 2: When the first slide bar 19 moves, it drives the first rotating bar 23 to move, and the first rotating bar 23 drives the slide groove 25 to slide on the outer wall of the fifth round bar 22, and the first rotating bar 23 rotates with the fifth round bar 22 as the center. The sixth round bar 31 is no longer squeezed below the first rotating bar 23, and the second tension spring 29 will contract, and the second rotating bar 27 is driven to rotate with the first fixed block 28 as the center through the sixth round bar 31. At this time, the second rotating bar 27 drives the one-way gear 26 to rotate toward the side of the fourth round bar 14, and the one-way gear 26 will abut against the outer wall of the fourth round bar 14. At this time, the second tension spring 29 stops contracting, and the one-way gear 26 rotates on the outer wall of the fourth round bar 14;

[0053] Step 3: As the male terminal 1 descends, when the first groove 101 is aligned with the first slide bar 19, the first slide bar 19 will slide into the first groove 101, and the inclined surface 20 on the first slide bar 19 will abut against the top of the first round rod 102. At this time, the first tension spring 12 contracts, so that the conical block 11 always abuts against the outer wall of the roller 24. Since the elastic coefficient of the first tension spring 12 is greater than that of the spring telescopic rod 10 and the spring 33, the spring telescopic rod 10 will pull the sealing cover 15 downward to abut against the second groove 8 to complete the closure;

[0054] Step 4: Since the first tension spring 12 is in an extended state at this time, when the sealing gasket 4 is used for a period of time and becomes deflated or hardened, in a static state, the first tension spring 12 will shrink downward, driving the conical block 11 to descend, and the conical block 11 squeezes the roller 24, and the roller 24 drives the first slide bar 19 to move away from the conical block 11. Since the inclined surface 20 of the first slide bar 19 abuts against the first round rod 102, the inclined surface 20 squeezes the first round rod 102, and the first round rod 102 drives the male terminal 1 to descend as a whole, squeezing the sealing gasket 4. Even if the sealing gasket 4 becomes deflated, the male terminal 1 and the sealing gasket 4 are always abutted to keep closed. At the same time, the male terminal 1 drives the fourth round rod 14 to move downward on the one-way gear 26;

[0055] When vibrating, the male terminal 1 and the female terminal 3 will follow the vibration, and the conical block 11 will follow the vibration. When the conical block 11 vibrates downward, it will squeeze the roller 24, and the roller 24 will drive the first slide bar 19 to move. The inclined surface 20 will increase the squeezing force on the first round rod 102. At this time, the male terminal 1 squeezes the sealing gasket 4 with greater force, so that the sealing gasket 4 fits the male terminal 1 more closely to keep it closed. The male terminal 1 drives the fourth round rod 14 to move downward on the one-way gear 26. When the conical block 11 vibrates upward, since the one-way gear 26 can only rotate in one direction, the one-way gear 26 will clamp the fourth round rod 14, and the fourth round rod 14 will not move upward, so the male terminal 1 and the female terminal 3 will not be separated during vibration.

[0056] The sixth step: when the sealing gasket 4 needs to be replaced and the sealing cover 15 needs to be separated, the sealing cover 15 is pulled upwards through the pull ring 16, and the sealing cover 15 drives the conical block 11 to rise through the spring telescopic rod 10 and stretches the first tension spring 12, and the conical block 11 no longer squeezes the roller 24, and the spring 33 is stretched out at this time, and drives the first sliding rod 19 to move toward the first groove 101 side through the second fixed block 32, and at this time, the first sliding rod 19 drives the first rotating rod 23 to move, and the first rotating rod 23 drives the slide groove 25 to move on the fifth round rod 22, and rotates with the fifth round rod 22 as the center of the circle, and the sixth round rod 31 will be squeezed under the first rotating rod 23, and the sixth round rod 31 drives the second rotating rod 27 to rotate in the opposite direction with the first fixed block 28 as the center of the circle until it abuts against the stopper 30, and at this time, the second rotating rod 27 drives the one-way gear 26 away from the fourth round rod 14, and at this time, the fourth round rod 14 can move upward, and the separation of the male terminal 1 and the female terminal 3 is completed.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
