Description

Technical Field

[0001] The invention relates to the technical field of connector locking and safety, and in particular to a miniaturized connector locking and safety device with a novel adapting boss structure. Background Art

[0002] Connectors are key components for realizing automotive electrical connections. In order to prevent the lock from being unlocked due to accidental contact, which may reduce the stability of the connector fixation and cause poor electrical contact or failure, connector locking insurance is added to connectors involved in key functions and safety functions of the vehicle to ensure the reliability of the connector electrical connection.

[0003] Traditional connector locking insurance is usually in the shape of a "mountain". Due to its structural characteristics, this type of connector locking insurance usually occupies a row of space alone or occupies a row of space together with the cavity hole, such as Fig.11 The figure shows a schematic diagram of a "mountain" shaped connector locking safety 6 occupying a row of space alone, wherein the "mountain" shaped connector locking safety 6 and the cavity hole 5 occupy a row of space respectively; Fig.12 The figure shows a schematic diagram of a "mountain"-shaped connector locking safety 6 and a cavity hole 5 occupying a row of space together.

[0004] The above-mentioned "mountain"-shaped connector locking safety needs to occupy a row of space or occupy a row of space together with the cavity holes in terms of spatial arrangement. The connector locking safety is not arranged in a row with the cavity holes, which is not conducive to the miniaturization of the entire connector locking safety device. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a miniaturized connector locking safety device with a novel adapter boss structure, which solves the technical problem that the existing "mountain"-shaped connector locking safety is not arranged in a row with the cavity hole, which is not conducive to the miniaturization of the entire connector locking safety device.

[0006] The technical solution of the present invention is achieved as follows: a miniaturized connector locking safety device with a new type of adapter boss structure includes a locking safety component, a female connector component and a male connector component that are plugged in and matched in sequence. When the locking safety component, the female connector component and the male connector component are matched, the locking safety component is located on the side of the female connector component and is arranged in a row with the cavity holes of the locking safety component and the female connector component.

[0007] Preferably, an elastic cantilever is provided on the side wall of the female connector assembly, a boss is provided on the elastic cantilever, and a hanging hole is provided on the male connector assembly; the locking safety assembly includes a limit plate, a guide unit is provided on the limit plate, and the guide unit is adjustably connected to the female connector assembly. When the locking safety assembly, the female connector assembly and the male connector assembly are matched, the boss of the female connector assembly and the hanging hole of the male connector assembly are matched to complete the primary locking, and the boss is pressed into the hanging hole by squeezing the elastic cantilever through the limit plate of the locking safety assembly to complete the secondary locking.

[0008] Preferably, the elastic cantilever is obliquely arranged on the female connector assembly.

[0009] Preferably, the guide unit comprises a fixed wedge, and a fixed gap is provided on the female connector assembly, and the fixed wedge is slidably matched with the fixed gap.

[0010] Preferably, an elastic hanging point is provided on the fixed wedge, and a hanging hole is provided along the fixed gap. The elastic hanging point is matched with the hanging hole and the position of the elastic hanging point in the hanging hole is adjustable.

[0011] Preferably, a positioning unit is provided on the limiting plate, a blocking platform is provided on the female connector assembly, and the positioning unit is engaged with the blocking platform.

[0012] Preferably, the positioning unit comprises a blocking cantilever, the bottom of which is connected to a blocking block, and when the locking safety assembly is plugged into the female connector assembly, the bottom surface of the blocking block is engaged with the top surface of the blocking platform.

[0013] Preferably, a trigger cantilever is connected to the blocking cantilever, and the top of the blocking cantilever and the top of the trigger cantilever are both connected to the limit plate, and a blocking block is connected to the bottom of the blocking cantilever. When the locking safety assembly and the female connector assembly are plugged in, the bottom surface of the blocking block is blocked and matched with the top surface of the blocking platform. When the locking safety assembly, the female connector assembly and the male connector assembly are plugged in sequentially, the trigger cantilever is interference-fitted with the inner wall of the male connector assembly, so that the bottom surface of the blocking block passes over the top surface of the blocking platform, and the limit plate is blocked and matched with the elastic cantilever.

[0014] Preferably, the top of the trigger cantilever is vertically connected to the limit plate, and the bottom of the trigger cantilever is bent to form an L shape. When the locking safety assembly, the female connector assembly and the male connector assembly are plugged in sequence, the bent end of the trigger cantilever has an interference fit with the inner wall of the male connector assembly.

[0015] Preferably, the bent end of the trigger cantilever is adapted to the hanging hole. When the locking safety assembly, the female connector assembly and the male connector assembly are matched, the bent end of the trigger cantilever slides into the hanging hole, and the top surface of the blocking block is blocked and matched with the bottom surface of the blocking platform.

[0016] Beneficial effects of the present invention: The locking safety component of the present invention is located on the side of the female connector component and is arranged in a row with the locking safety component and the cavity hole of the female connector component. There is no need for multiple rows, which is conducive to miniaturized arrangement in a narrow space and miniaturization of the entire connector locking safety device.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1, a novel miniaturized connector locking safety device with an adaptable boss structure, such as Figure 1 , Figure 2 , Figure 7 and Fig.10 As shown, it includes a locking safety component 1, a female connector component 2 and a male connector component 3 that are plugged in and matched in sequence. When the locking safety component 1, the female connector component 2 and the male connector component 3 are matched, the locking safety component 1 is located on the side of the female connector component 2 and is arranged in a row with the cavity hole 5 of the locking safety component 1 and the female connector component 2. The locking safety component 1 of the present invention is located on the side of the female connector component 2 and is arranged in a row with the cavity hole 5 of the locking safety component 1 and the female connector component 2. There is no need for multiple rows, which is conducive to the miniaturized arrangement in a narrow space. The volume of the corresponding male connector component 3 is also reduced accordingly, which is conducive to the miniaturization of the entire connector locking safety device, and solves the technical problem that the existing "mountain"-shaped connector locking safety is not arranged in a row with the cavity hole, which is not conducive to the miniaturization of the entire connector locking safety device.

[0033] Embodiment 2, based on embodiment 1, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 1 , Figure 2 , Figure 7 and Fig.10As shown, the side wall of the female connector assembly 2 is provided with an elastic cantilever 2.1, the elastic cantilever 2.1 is provided with a boss 2.5, and the male connector assembly 3 is provided with a hanging hole 3.1; the locking and safety assembly 1 includes a limit plate 1.1, the limit plate 1.1 is provided with a guide unit, and the guide unit is connected to the female connector assembly 2 in an adjustable position. When the locking and safety assembly 1, the female connector assembly 2 and the male connector assembly 3 are matched, the boss 2.5 of the female connector assembly 2 and the hanging hole 3.1 of the male connector assembly 3 are hung and matched to complete the primary locking, and the limit plate 1.1 of the locking and safety assembly 1 squeezes the elastic cantilever 2.1 to press the boss 2.5 into the hanging hole 3.1 to complete the secondary locking. The primary locking realizes the clamping of the female connector assembly 2 and the male connector assembly 3, and the purpose of the secondary locking is to ensure the stability of the clamping of the female connector assembly 2 and the male connector assembly 3.

[0034] Embodiment 3, based on embodiment 2, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown, the elastic cantilever 2.1 is tiltedly arranged on the female connector assembly 2. The elastic cantilever 2.1 is tiltedly arranged on the female connector assembly 2, which facilitates the plugging and mating of the female connector assembly 2 and the male connector assembly 3, and the tilted elastic cantilever 2.1 increases the difficulty of the boss 2.5 to be separated from the hanging hole 3.1, thereby improving the retention force of the mating connection between the female connector assembly 2 and the male connector assembly 3.

[0035] Example 4, based on Example 3, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 3 , Figure 4 and Figure 6 As shown, the guide unit includes a fixed wedge 1.2, and a fixed gap 2.3 is provided on the female connector assembly 2. The fixed wedge 1.2 and the fixed gap 2.3 are slidably matched. The sliding match between the fixed wedge 1.2 and the fixed gap 2.3 realizes the position movement of the entire locking and safety assembly 1 on the female connector assembly 2, and the fixed wedge 1.2 plays a guiding role in the position movement of the entire locking and safety assembly 1 on the female connector assembly 2.

[0036] Example 5, based on Example 4, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 3 , Figure 4 and Figure 6As shown, the fixed wedge 1.2 is provided with an elastic hanging point 1.3, and a hanging hole 2.4 is provided along the fixed gap 2.3. The elastic hanging point 1.3 is matched with the hanging hole 2.4 and the position of the elastic hanging point 1.3 is adjustable in the hanging hole 2.4. The elastic hanging point 1.3 is matched with the hanging hole 2.4 and the position of the elastic hanging point 1.3 is adjustable in the hanging hole 2.4. That is, the elastic hanging point 1.3 is provided on the fixed wedge 1.2, so that the moving distance of the entire locking safety component 1 under the guidance of the fixed wedge 1.2 is controlled, and the moving distance of the locking safety component 1 is the distance that the elastic hanging point 1.3 can move in the hanging hole 2.4. At the same time, the elastic hanging point 1.3 is hung in the hanging hole 2.4 to ensure that the locking safety component 1 cannot be easily withdrawn from the female connector component 2.

[0037] Embodiment 6, based on any one of Embodiments 2 to 5, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the limit plate 1.1 is provided with a positioning unit, the female connector assembly 2 is provided with a blocking platform 2.2, and the positioning unit and the blocking platform 2.2 are engaged with each other. The positioning unit and the blocking platform 2.2 are arranged to limit the position of the locking insurance assembly 1 on the female connector assembly 2, and the locking cooperation between the positioning unit and the blocking platform 2.2 further increases the stability of the locking insurance assembly 1 connected to the female connector assembly 2.

[0038] Embodiment 7, based on embodiment 6, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the positioning unit includes a blocking cantilever 1.6, and a blocking block 1.4 is connected to the bottom of the blocking cantilever 1.6. When the locking and insurance component 1 is plugged into the female connector component 2, the bottom surface of the blocking block 1.4 is blocked and matched with the top surface of the blocking platform 2.2. The bottom surface of the blocking block 1.4 is blocked and matched with the top surface of the blocking platform 2.2 to limit the position of the locking and insurance component 1 inserted into the female connector component 2, thereby distinguishing the shipping position and the working position of the locking and insurance component 1. When the locking and insurance component 1 is in the shipping position, the bottom surface of the blocking block 1.4 is blocked and matched with the top surface of the blocking platform 2.2.

[0039] Embodiment 8, based on embodiment 7, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, the blocking cantilever 1.6 is connected to a trigger cantilever 1.5, the top of the blocking cantilever 1.6 and the top of the trigger cantilever 1.5 are both connected to the limit plate 1.1, and the bottom of the blocking cantilever 1.6 is connected to a blocking block 1.4. When the locking insurance component 1 is plugged into the female connector component 2, the bottom surface of the blocking block 1.4 is blocked and matched with the top surface of the blocking platform 2.2. When the locking insurance component 1, the female connector component 2 and the male connector component 3 are plugged in sequence, the trigger cantilever 1.5 is interference-fitted with the inner wall of the male connector component 3, so that the bottom surface of the blocking block 1.4 passes over the top surface of the blocking platform 2.2, and the limit plate 1.1 is blocked and matched with the elastic cantilever 2.1. When the locking safety component 1 is plugged into the female connector component 2, the bottom surface of the blocking block 1.4 is engaged with the top surface of the blocking platform 2.2, and the locking safety component 1 is in the shipping position; when the female connector component 2 equipped with the locking safety component 1 is plugged into the male connector component 3, the trigger cantilever 1.5 is interference-fitted with the inner wall of the male connector component 3, so that the bottom surface of the blocking block 1.4 passes over the top surface of the blocking platform 2.2, and the limit plate 1.1 is engaged with the elastic cantilever 2.1, and the locking safety component 1 is in the working position.

[0040] That is, the blocking block 1.4 on the locking safety component 1 hits the blocking platform 2.2 on the female connector component 2 to ensure that the locking safety component 1 cannot easily move from the shipping position to the working position. When the female connector component 2 and the male connector component 3 are plugged into each other, the upper inner wall of the hanging hole 3.1 on the male connector component 3 will touch the trigger cantilever 1.5 on the locking safety component 1. After the trigger cantilever 1.5 moves, the blocking block 1.4 moves along with it. The blocking block 1.4 moves from the top surface of the blocking platform 2.2 to the bottom surface, and the locking safety component 1 can be switched to the working position state.

[0041] Embodiment 9, based on embodiment 8, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the top of the trigger cantilever 1.5 is vertically connected to the limit plate 1.1, and the bottom of the trigger cantilever 1.5 is bent to form an L shape. When the locking and insurance component 1, the female connector component 2 and the male connector component 3 are plugged in sequence, the bent end of the trigger cantilever 1.5 is interference-fitted with the inner wall of the male connector component 3. That is, when the female connector component 2 and the male connector component 3 are plugged in, the inner wall above the hanging hole 3.1 on the male connector component 3 will touch the bent end of the trigger cantilever 1.5 on the locking and insurance component 1, thereby causing the trigger cantilever 1.5 to deform and move. After 1.5 moves, the blocking block 1.4 moves with it, and the blocking platform 2.2 no longer blocks the blocking block 1.4, and the locking and insurance component 1 can be switched to the working state.

[0042] Example 10, based on Example 9, a new type of miniaturized connector locking safety device with an adaptable boss structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the bent end of the trigger cantilever 1.5 is matched with the hanging hole 3.1. When the locking and insurance component 1, the female connector component 2 and the male connector component 3 are matched, the bent end of the trigger cantilever 1.5 slides into the hanging hole 3.1, and the top surface of the blocking block 1.4 is blocked and matched with the bottom surface of the blocking platform 2.2. When the locking and insurance component 1 is switched to the working state, the trigger cantilever 1.5 moves into the hanging hole 3.1, and the trigger cantilever 1.5 is no longer subjected to the force of the inner wall of the male connector component 3, and the trigger cantilever 1.5 rebounds, and the blocking platform 2.2 is blocked and matched with the blocking block 1.4 again, ensuring that the locking and insurance component 1 cannot be easily switched back to the shipping state.

[0043] Among them, the bending angle of the bottom of the trigger cantilever 1.5 is greater than 90° and less than 150°, and the preferred bending angle of the bottom of the trigger cantilever 1.5 is 120°. This arrangement makes it easier for the bent end of the trigger cantilever 1.5 to be squeezed and deformed by the male connector component 3 when the female connector component 2 and the male connector component 3 are matched, which is conducive to realizing the movement generated by the deformation of the trigger cantilever 1.5.

[0044] When implementing Example 10, first, the locking safety component 1 is plugged into the female connector component 2. At this time, the fixed wedge 1.2 and the fixed gap 2.3 are slidably matched, the elastic hanging point 1.3 is adapted to the hanging hole 2.4 and the elastic hanging point 1.3 moves in the hanging hole 2.4, and after the locking safety component 1 is pressed down, the bottom surface of the blocking block 1.4 and the top surface of the blocking platform 2.2 are blocked and matched, so that the locking safety component 1 is in the shipping position state. When the locking safety component 1 needs to be switched to the working position state, the locking safety component 1 and the female connector component 2 in the shipping position state are plugged into the male connector component 3 as a whole, and the boss 2.5 of the female connector component 2 and the hanging hole 3.1 of the male connector component 3 are hung and matched to complete a locking operation; at this time, the bent end of the trigger cantilever 1.5 is interference-fitted with the inner wall of the male connector component 3, and under the extrusion of the inner wall of the male connector component 3, the trigger cantilever 1.5 is deformed and displaced. After 1.5 moves, the blocking block 1.4 moves along with it, and the blocking platform 2.2 is disengaged from the blocking block 1.4. At this time, the locking insurance component 1 is continued to be pressed down, and the blocking block 1.4 moves downward from the top surface of the blocking platform 2.2 to the bottom surface of the blocking platform 2.2, and at the same time, the cantilever 1.5 is triggered to move into the hanging hole 3.1, and the cantilever 1.5 is no longer subjected to the force of the inner wall of the male connector component 3, and the cantilever 1.5 is triggered to rebound, and the blocking platform 2.2 is again separated from the blocking block 1.4. The stopper 1.4 cooperates with the stopper 1.4, and when the stopper 1.4 moves downward, it drives the limit plate 1.1 to move downward. When the cantilever 1.5 is triggered to move into the hanging hole 3.1, the limit plate 1.1 just moves to the back of the elastic cantilever 2.1 and squeezes the elastic cantilever 2.1. The limit plate 1.1 squeezes the elastic cantilever 2.1 to press the boss 2.5 into the hanging hole 3.1. The squeezing of the limit plate 1.1 makes it impossible for the boss 2.5 to withdraw from the hanging hole 3.1, thus completing the secondary locking.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
