Description

Technical Field

[0001] This utility model relates to the field of electrical connection device technology, and in particular to a connector mainly used in automotive turn signals and other devices to achieve electrical connections. Background Technology

[0002] A common type of connector typically includes a rubber base, a rubber shell, and female terminals, and is used in automotive applications such as 2-pin power connectors for turn signals. These connectors require high stability; otherwise, they are prone to loosening, affecting the normal operation of the equipment. For example, Chinese utility model patent CN201821200392.6 discloses a novel connector that uses a spring-loaded latch to strengthen the connection and prevent the connector from falling off; it also includes a baffle and a rear wall to prevent the connector from loosening and shaking, ensuring a stable connection. However, connectors that rely primarily on spring-loaded latches, baffles, and rear walls for fixation and stabilization still have insufficient structural strength, stability, and anti-loosening performance, especially when used as automotive-grade connectors in equipment with high vibration, where loosening and poor contact are still relatively common. Utility Model Content

[0003] This invention addresses the shortcomings of existing automotive turn signal connectors in terms of structural strength and stability by providing a 2-pin automotive-grade power connector for automotive turn signals that features a more rational structural design, higher combined strength, and better stability and reliability.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a 2-pin automotive-grade power connector for automotive turn signals, comprising a base, a housing, a positioning auxiliary component, a male terminal, and a female terminal. The base is inserted into the housing, and the male and female terminals are interlocked in two terminal holes of the base.

[0008] Furthermore, a first anti-mistake rib and a second anti-mistake rib are respectively provided on the outer sides of the two abutting surfaces of the rubber base. The protrusion height of the first anti-mistake rib is greater than that of the second anti-mistake rib. After the positioning auxiliary component is inserted and fixed to the rubber base, the first anti-mistake rib and the second anti-mistake rib will block the two abutting wings on the inner side. An anti-mistake extension is provided on the side of the rubber shell corresponding to the first anti-mistake rib so that the height of this side inside the rubber shell is greater than the height of the other side. After the rubber base and the positioning auxiliary component are inserted into the rubber shell together, the first anti-mistake rib abuts against the inner side of the anti-mistake extension.

[0009] Furthermore, reinforcing ribs are provided on both sides of the positioning auxiliary component at the positions of the protrusion and the pressing part, forming a side blocking structure for the protrusion and the pressing part; the tail of the reinforcing rib forms a rear blocking part, forming a rear blocking structure for the pressing part.

A protruding limiting piece is provided next to the limiting part of the female terminal. After the female terminal is inserted into the terminal hole, it is engaged with the limiting channel by the limiting piece to form a reinforced limiting structure for the female terminal, thereby improving the stability of the female terminal.

[0013] Preferably, the tail end of the terminal hole is provided with an arc-shaped bottom surface corresponding to the tail end wiring part of the female terminal, and the arc-shaped part of the wiring part of the female terminal is provided on the arc-shaped bottom surface of the terminal hole.

[0014] This invention provides good tightness and strength by providing an abutment surface on the rubber base, and abutment wings and multiple independent plug-in parts on the positioning auxiliary component.

Detailed Implementation

[0025] In this embodiment, refer to Figures 1-9 A 2-pin automotive-grade power connector for automotive turn signals includes a base 1, a housing 2, a positioning auxiliary component 3, a male terminal 4, and a female terminal 5. The base 1 is inserted into the housing 2. The male terminal 4 and the female terminal 5 are inserted into each other in two terminal holes 10 of the base 1, achieving electrical connection. Abutment surfaces 11 are provided on both sides of the base 1, opposite to the two terminal holes 10. Two insertion grooves 14 are provided between the two abutment surfaces 11 along the front-rear direction. Limiting holes are provided on the abutment surfaces 11, communicating with the terminal holes 10. The positioning auxiliary component 3 extends to both sides with abutment wings 31 that mate with the abutment surfaces 11. The abutment wings 31 cover the abutment surfaces 11, thus securing the positioning auxiliary component 3. On the base 1, a connector 32 and abutment 35 are respectively provided on the bottom surface of the positioning auxiliary component 3, opposite to the insertion groove 14 and the limiting hole. The positioning auxiliary component 3 is inserted into the insertion groove 14 by the connector 32 to fix the positioning auxiliary component 3 to the base 1. The abutment 35 is inserted into the limiting hole to abut against the female terminal 5 to improve the stability of the female terminal 5. A protruding buckle 37 and a pressing part 38 are provided on the positioning auxiliary component 3. A buckle hole 21 is provided on the housing 2. After the positioning auxiliary component 3 is inserted into the housing 2 together with the base 1, it is locked and fixed to the housing 2 by the protruding buckle 37 snapping into the buckle hole 21. By pressing the pressing part 38, the protruding buckle 37 is disengaged from the buckle hole 21, so that the entire connector can be disassembled.

[0026] A snap-fit ​​groove 15 is provided at both the front and rear ends between the two abutting surfaces 11 of the rubber base 1. A snap-fit ​​arm 33 is provided at the front and rear ends of the bottom surface of the positioning auxiliary component 3. After the positioning auxiliary component 3 is inserted and fixed to the rubber base 1, the two snap-fit ​​arms 33 are respectively snapped into the two snap-fit ​​grooves 15 to achieve the snap-fit ​​of the rubber base 1 from both the front and rear ends, further improving the stability of the connection 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 buckled 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] Refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown in, 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 have 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, thereby minimizing the lateral dimension of the entire connector while maintaining sufficient strength, which is beneficial to miniaturization.

[0029] On the outer sides of the two abutting surfaces 11 of the rubber seat 1, a raised first anti-fooling rib 12 and a second anti-fooling rib 13 are respectively provided. 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, playing a role in anti-collision, and can also prevent the positioning auxiliary member 3 from tilting to both sides and being completely unlocked in the state of the first lock. On one side of the rubber shell 2 corresponding to the first anti-fooling rib 12, a section of anti-fooling extension 22 is provided, so that the height of this side inside the rubber shell 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 shell 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 shell 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 forms an upward 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 anti-collision.

[0031] Such as Figure 9As shown, a limiting member 51 is provided inside the female terminal 5. After the male terminal 4 and the female terminal 5 are inserted into each other, the male terminal 4 is inserted into the limiting member 51. A protruding limiting part 52 is provided on the top of the limiting member 51. The limiting hole includes a first limiting hole 17. A locking platform 18 protruding into the terminal hole 10 is provided in the first limiting hole 17. By the locking platform 18 abutting against the limiting part 52, the female terminal 5 can be prevented from moving back, thereby improving the stability of the terminal connection.

[0032] A primary locking member 53 extending downward is provided on both sides of the limiting part 52. A locking groove 54 is provided on the side wall of the female terminal 5 at the position corresponding to the primary locking member 53. The primary locking member 53 is inserted into the locking groove 54 to block the limiting member 51 inside the main body of the female terminal 5.

[0033] A secondary locking member 55 is provided behind the limiting part 52. The limiting hole also includes a second limiting hole 19. An abutment member 35 is provided on the bottom surface of the positioning auxiliary member 3 at a position corresponding to the second limiting hole 19. The abutment member 35 is inserted from the second limiting hole 19 and abuts against the top of the female terminal 5 and the rear of the secondary locking member 55, thus providing a secondary stop for the female terminal 5. A limiting channel 110 is provided in the partition between the first limiting hole 17 and the second limiting hole 19. The two ends of the limiting channel 110 and one side adjacent to the terminal hole 10 are open. A protruding limiting piece 56 is provided next to the limiting part 52 of the female terminal 5. After the female terminal 5 is inserted into the terminal hole 10, it is locked into the limiting channel 110 by the limiting piece 56 to form a reinforced limiting structure for the female terminal 5, thereby improving the stability of the female terminal 5.

[0034] The tail end of the terminal hole 10 is set with an arc-shaped bottom surface corresponding to the tail end wiring part of the female terminal 5. The arc-shaped part of the wiring part of the female terminal 5 is set on the arc-shaped bottom surface of the terminal hole 10, which helps to further stabilize the female terminal 5.

[0035] It should be noted that the terms "front," "back," "left," "right," "up," "down," "top," and "bottom," etc., used in this utility model to refer to directions or positions, are specific to this utility model. Figures 1-8 The illustrated embodiment uses a specific viewpoint, with the left side representing the front, the right side the back, the top the ceiling, and the bottom the ceiling. As the angle of the view changes, the corresponding direction and position may also change.

The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
