Detailed implementation manner
[0025] In this embodiment, with reference to Figures 1-9 , an automotive turn signal 2PIN power vehicle specification connector includes a rubber base 1, a rubber shell 2, a positioning auxiliary part 3, a male terminal 4 and a female terminal 5. The rubber base 1 is inserted into the rubber shell 2. The male terminal 4 and the female terminal 5 are inserted into each other in the two terminal holes 10 of the rubber base 1 to achieve electrical connection. Contact surfaces 11 are provided on both sides of the rubber base 1, and the two contact surfaces 11 are opposite to the two terminal holes 10. Two plugging grooves 14 are arranged in the front-back direction between the two contact surfaces 11, and limiting holes are provided on the contact surfaces 11, and the limiting holes communicate with the terminal holes 10. The positioning auxiliary part 3 extends outwards on both sides with contact wings 31 that match the contact surfaces 11, and the positioning auxiliary part 3 is buckled on the rubber base 1 by covering the contact wings 31 on the contact surfaces 11. Plugging parts 32 and contact parts 35 are respectively arranged at positions on the bottom surface of the positioning auxiliary part 3 opposite to the plugging grooves 14 and the limiting holes. The positioning auxiliary part 3 is fixedly plugged with the rubber base 1 by inserting the plugging parts 32 into the plugging grooves 14, and the contact part 35 is inserted into the limiting hole to abut against the female terminal 5 to improve the stability of the female terminal 5. A convex buckle 37 and a pressing part 38 are provided on the positioning auxiliary part 3, and a buckling hole 21 is provided on the rubber shell 2. After the positioning auxiliary part 3 is inserted into the rubber shell 2 together with the rubber base 1, it is locked and fixed with the rubber shell 2 by buckling the convex buckle 37 into the buckling hole 21. By pressing the pressing part 38, the convex buckle 37 is disengaged from the buckling hole 21, so that the entire connector can be disassembled.
[0026] Snap grooves 15 are respectively arranged at the front and rear ends between the two contact surfaces 11 of the rubber base 1, and snap arms 33 are respectively arranged at the front and rear end positions in the middle of the bottom surface of the positioning auxiliary part 3. After the positioning auxiliary part 3 is fixedly plugged with the rubber base 1, the two snap arms 33 are respectively buckled into the two snap grooves 15 to buckle the rubber base 1 from the front and rear ends, further improving the combination stability with the rubber base 1.
[0027] A buckle 16 is provided on the groove wall of the buckle groove 15, and a buckle hole 34 is provided on the buckle arm 33. After the buckle arm 33 is inserted into the buckle groove 15, each buckle hole 34 buckles the corresponding buckle 16, so that the positioning auxiliary member 3 is not easily detached from the rubber seat 1.
[0028] Referring to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , the cross-section of the rubber seat 1 has a structure similar to an "eight" shape, its two terminal holes 10 are in different planes, and the two abutting surfaces 11 are inclined surfaces facing outward and downward, forming an angle of about 150-170 degrees. The two abutting wings 31 of the positioning auxiliary member 3 also present an inclined structure corresponding to the two abutting surfaces 11. In addition to adapting to the structure of the installation part, this non-flat structure can also reduce the distance between the two terminal holes, so as to minimize the lateral dimension of the entire connector while maintaining sufficient strength, which is beneficial to miniaturization.
[0029] A raised first anti-fooling rib 12 and a second anti-fooling rib 13 are respectively provided on the outer sides of the two abutting surfaces 11 of the rubber seat 1. The raised height of the first anti-fooling rib 12 is greater than that of the second anti-fooling rib 13. After the positioning auxiliary member 3 is inserted and fixed to the rubber seat 1, the two abutting wings 31 are blocked inside by the first anti-fooling rib 12 and the second anti-fooling rib 13. This can raise both sides, play a role in preventing collision, and also prevent the positioning auxiliary member 3 from tilting to both sides and being completely unlocked in the state of a single lock. A section of anti-fooling extension 22 is provided on the side of the rubber housing 2 corresponding to the first anti-fooling rib 12, so that the height of this side inside the rubber housing 2 is greater than that of the other side. After the rubber seat 1 and the positioning auxiliary member 32 are inserted into the rubber housing together, the first anti-fooling rib 12 abuts against the inside of the anti-fooling extension 22. This structure with one high and one low can play an anti-fooling effect when being inserted into the rubber housing 2, improving the accuracy and efficiency of assembly.
[0030] Reinforcing ribs 36 are provided at positions on both sides of the positioning auxiliary member 3 where the convex buckle 37 and the pressing part 38 are located, and a side blocking structure for the convex buckle 37 and the pressing part 38 is formed by the reinforcing ribs 36. It can not only prevent the weak part from breaking, but also play a role in anti-collision; the tail of the reinforcing rib 36 is formed with an upper rear blocking part 39, and a rear blocking structure for the pressing part 38 is formed by the rear blocking part 39, which can prevent the convex buckle 37 from breaking beyond the threshold, and at the same time play a role in preventing the convex buckle 37 from being accidentally unlocked due to collision.
[0031] As Figure 9As shown, a limiting member 51 is provided inside the female terminal 5. After the male terminal 4 is inserted into the female terminal 5, it is inserted into the limiting member 51. A protruding limiting portion 52 is provided at the top of the limiting member 51. The limiting hole includes a first limiting hole 17, and a locking platform 18 protruding towards the terminal hole 10 is provided in the first limiting hole 17. By abutting the limiting portion 52 against the locking platform 18, the female terminal 5 can be prevented from retreating, improving the stability during terminal docking.
[0032] On both sides of the limiting portion 52, a primary locking member 53 extending downward is provided. At a position corresponding to the primary locking member 53 on the side wall of the female terminal 5, a locking groove 54 is provided. The primary locking member 53 is snapped into the locking groove 54 to lock the limiting member 51 inside the main body of the female terminal 5.
[0033] A secondary locking member 55 is provided behind the limiting portion 52. The limiting hole further includes a second limiting hole 19. At a position corresponding to the second limiting hole 19 on the bottom surface of the positioning auxiliary member 3, an abutting member 35 is provided. The abutting member 35 is inserted from the second limiting hole 19 to abut above the female terminal 5 and behind the secondary locking member 55, providing a secondary blocking effect on the female terminal 5. A limiting channel 110 is provided in the partition portion between the first limiting hole 17 and the second limiting hole 19. Both ends of the limiting channel 110 and one side adjacent to the terminal hole 10 are open. A protruding limiting piece 56 is provided beside the limiting portion 52 of the female terminal 5. After the female terminal 5 is inserted into the terminal hole 10, the limiting piece 56 is snapped into the limiting channel 110 to form a strengthened limiting structure for the female terminal 5, improving the stability of the female terminal 5.
[0034] At the tail of the terminal hole 10, the position corresponding to the tail wiring portion of the female terminal 5 is provided with a circular arc bottom surface. The arc portion of the wiring portion of the female terminal 5 is arranged on the circular arc bottom surface of the terminal hole 10, which is beneficial to further stabilizing the female terminal 5.
