Description

Technical Field

[0001] This utility model relates to the field of automotive electronic connector technology, specifically a stable connector for automotive wiring harness mating. Background Technology

[0002] Automotive wiring harness terminal connectors are key components of automotive electrical systems. Although small, they are the "lifeline" of automotive electrical systems, responsible for electrical connections, signal transmission, and providing protection and safety functions.

[0003] The prior art (Chinese patent publication number CN213692430U, publication date 2021-07-13) discloses a terminal hole structure for an automotive connector, including female terminals, female connectors, male connectors, and male terminals. The female connector has two rows of female terminals installed at intervals in the front and rear, each with a terminal hole at its lower end. The male connector has two rows of male terminals installed at intervals in the front and rear, each with a locking tongue at its upper end. The locking tongues of the male terminals match the terminal holes of the corresponding female terminals. The terminal holes of the front and rear rows of female terminals are staggered. Testing has shown that this structure can significantly reduce the connector insertion force by approximately 40%, demonstrating good improvement and low cost, and has significant potential for widespread application.

[0004] While existing technologies can reduce connector insertion force, most connectors rely solely on their own locking force for limiting the male and female ends during assembly, without providing secondary limiting. Consequently, the male and female ends are prone to detachment during normal use, resulting in poor stability.

[0005] Therefore, we propose a stable connector for automotive wiring harness mating to address the aforementioned issues. Summary of the Invention

[0006] The purpose of this invention is to provide a stable connector for automotive wiring harness assembly, in order to solve the problem mentioned in the background art that, when the male and female ends of the connector are assembled, they mostly rely on their own clamping force for limiting, and the male and female ends cannot be limited for secondary limiting. Under normal use, the male and female ends are prone to separation, resulting in poor stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stable connector for automotive wiring harness mating, comprising a female connector end and a male connector end for assembly and mating with it, wherein the male connector end is provided with an abutment mechanism on its side, the abutment mechanism including a deformable abutment piece, the deformable abutment piece being deformed by the mating action of the female connector end, thereby further abutting and limiting the assembly of the female connector end and the male connector end.

[0008] Furthermore, the male end of the connector is provided with a PIN protection plate inside to provide accurate positioning for terminal connection, and both the side of the male end and the side of the female end of the connector are slidably provided with locking keys for secondary locking of their assembly, while a sealing gasket is provided on the outside of the male end of the connector.

[0009] Furthermore, a pull rod groove is provided on the side of the female end of the connector, and a pull rod body is nested inside the pull rod groove, and a limit slider is fixedly connected to the inner side of the pull rod body.

[0010] Furthermore, the male end of the connector is provided with a guide groove on its side, and there are four sets of guide grooves and limit sliders. The guide groove is set with an inclined structure. The connector has two forms: 39 holes and 68 holes.

[0011] Furthermore, an abutment airbag is fixedly connected to the inner side of the guide groove, and an expansion airbag is fixedly connected to the side of the male end of the connector, and a connecting hose is connected through the expansion airbag and the abutment airbag.

[0012] Furthermore, a deformable abutment is fixedly connected to the side of the male end of the connector, and the deformable abutment is located on the side of the inflatable airbag, and the deformable abutment is arranged in an arc-shaped deformable structure.

[0013] Furthermore, the limiting slider forms a sliding structure through the pull rod body and the guide groove. When the connector female end and the connector male end are connected, the side of the deformable contact piece and the inner side of the connector female end are in contact with each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The connectors are available in 39-hole and 68-hole configurations. Different specifications of connectors can meet the needs of different usage conditions. Both the female and male connector ends are injection molded from glass fiber reinforced polyester, which has impact and vibration resistance characteristics and can provide fixed position support for terminal connection. In addition, the sides of both the female and male connector ends are provided with anti-misalignment grooves to ensure correct assembly with mating ends.

[0016] 2. The PIN protection plate set on the inner side of the male end of the connector can provide accurate positioning for the terminal connection. After the terminal connection is positioned, it can be locked a second time by the locking key, thereby ensuring the stability of high-frequency terminal insertion and removal. The sealing gasket can ensure the stability of electrical contact and also play a waterproof role between the sheet metal and the connector.

[0017] 3. After the initial docking of the female and male connector ends is completed, the limiting slider, which is located inside the pull rod body, is now on the outer side of the guide groove. Pushing the pull rod body inward causes it to slide stably along the inside of the pull rod groove, which in turn drives the limiting slider to slide stably along the inside of the guide groove. The limiting slider slides to the inner side of the guide groove, where it is then positioned to prevent it from slipping out. Through the cooperation between the limiting slider and the guide groove, the assembly of the female and male connector ends is limited, preventing them from becoming loose.

[0018] 4. As the limiting slider slides along the inside of the guide groove, it simultaneously compresses the expansion airbag. This causes the expansion airbag to deliver the gas stored inside to the interior of the contact airbag through the connecting hose, causing the contact airbag to expand. The expanded contact airbag then contacts the deformable contact piece, causing it to deform. The deformed contact piece then comes into contact with the inner wall of the connector female end, resulting in a tighter mating between the connector female end and the connector male end, thus improving the stability of the mating.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The technical solution shown herein provides the following technical solution: a stable connector for automotive wiring harness mating, which discloses: a female connector 1 and a male connector 2 that assembles and mates with it. The male connector 2 is provided with a PIN protection plate 13 inside to provide accurate positioning for terminal connection, and both the side of the male connector 2 and the side of the female connector 1 are slidably provided with locking keys 7 for secondary locking of their assembly. At the same time, a sealing gasket 12 is provided on the outside of the male connector 2.

[0029] The connector is available in 39-pin and 68-pin configurations, with different specifications to meet the needs of various usage conditions. Both the female connector 1 and the male connector 2 are injection molded from glass fiber reinforced polyester, providing impact and vibration resistance and offering fixed position support for the terminal connection. Anti-misalignment grooves are provided on the sides of both the female connector 1 and the male connector 2 to ensure correct assembly with the mating terminals. The PIN protection plate 13 inside the male connector 2 provides accurate positioning for the terminal connection. After the terminal connection is positioned, it can be locked a second time using the locking key 7, ensuring the stability of high-frequency terminal insertion and removal. The sealing gasket 12 ensures the stability of electrical contact and also provides waterproofing between the sheet metal and the connector.

[0030] Example 2: Figure 2 , Figure 3 , Figure 4 and Figure 6The technical solution shown herein provides the following technical solution: a stable connector for automotive wiring harness docking, comprising a pull rod body 3, wherein the movement of the pull rod body 3 can achieve assembly and positioning of the connector female end 1 and the connector male end 2: a pull rod groove 4 is provided on the side of the connector female end 1, and the pull rod body 3 is nested inside the pull rod groove 4, and a limiting slider 5 is fixedly connected to the inner side of the pull rod body 3; a guide groove 6 is provided on the end side of the connector male end 2, and four sets of both the guide groove 6 and the limiting slider 5 are provided; the guide groove 6 is set with an inclined structure; the connector has two forms: 39 holes and 68 holes; an abutment airbag 8 is fixedly connected to the inner side of the guide groove 6, and an expansion airbag 9 is fixedly connected to the side of the connector male end 2; and a connecting hose 10 is connected through the expansion airbag 9 and the abutment airbag 8.

[0031] After the initial docking of the female connector 1 and the male connector 2 is completed, the limiting slider 5, which is set inside the pull rod body 3, is located on the outer end of the guide groove 6. Pushing the pull rod body 3 inward, the pull rod body 3 slides stably along the inside of the pull rod groove 4, thereby further driving the limiting slider 5 to slide stably along the inside of the guide groove 6, so that the limiting slider 5 slides to the inside of the guide groove 6. At this time, the guide groove 6 can limit the limiting slider 5 to prevent the limiting slider 5 from slipping off. Through the mutual cooperation of the limiting slider 5 and the guide groove 6, the assembly of the female connector 1 and the male connector 2 is limited, preventing the female connector 1 and the male connector 2 from becoming loose.

[0032] Example 3: Figure 2 , Figure 4 and Figure 5 The present invention provides the following technical solution: a stable connector for automotive wiring harness docking, which discloses an abutment mechanism. The abutment mechanism can make the docking between the female connector 1 and the male connector 2 more tight through the deformation of the deformable abutment piece 11. The abutment mechanism is provided on the side of the male connector 2. The abutment mechanism includes a deformable abutment piece 11. The deformable abutment piece 11 is deformed by the docking action of the female connector 1, thereby further abutting and limiting the assembly of the female connector 1 and the male connector 2. The deformable abutment piece 11 is fixedly connected to the side of the male connector 2. The deformable abutment piece 11 is located on the side of the inflatable airbag 9. The deformable abutment piece 11 is set in an arc-shaped deformable structure. The limiting slider 5 forms a sliding structure through the pull rod body 3 and the guide groove 6. When the female connector 1 and the male connector 2 dock, the side of the deformable abutment piece 11 and the inner side of the female connector 1 are in contact with each other.

[0033] While the limiting slider 5 slides along the inside of the guide groove 6, it simultaneously squeezes the expansion airbag 9, causing the expansion airbag 9 to deliver the gas stored inside to the inside of the contact airbag 8 through the connecting hose 10. This causes the contact airbag 8 to expand, and the expanded contact airbag 8 can contact the deformable contact piece 11, causing the deformable contact piece 11 to deform. The deformed contact piece 11 can then contact the inner wall of the connector female end 1, making the connection between the connector female end 1 and the connector male end 2 tighter and improving the stability of the connection.
