Description

Technical Field

[0001] The present invention relates to the technical field of automotive wire harness assemblies, and particularly to an automotive wire harness assembly with quick connectors. Background Art

[0002] In the era of the booming development of the current automotive industry, the intelligent and electrified processes of automobiles are accelerating continuously, and automotive electronic systems have become increasingly complex and diverse. From basic lighting and audio systems to advanced autonomous driving assistance systems and battery management systems for new energy vehicles, the operation of numerous electronic devices depends on efficient and stable circuit connections. As the "neural network" of the automotive circuit, the importance of the automotive wire harness assembly is self-evident. The automotive wire harness assembly is responsible for connecting electronic components in various parts of the vehicle to achieve power transmission and signal transmission, ensuring the normal operation of various functions of the vehicle. With the increasing richness of automotive functions, the number of in-vehicle electronic devices has increased sharply, and the requirements for the wire harness assembly have also become higher and higher.

[0003] For example, the Chinese invention patent with the application number 202321201555.3 discloses an automotive wire harness assembly that is easy to disassemble and assemble. By setting a wire harness plug connector, a wire harness connection head, and a disassembly-friendly positioning mechanism, when the user needs to connect the wire harness plug connector and the wire harness connection head, they only need to align the right side of the wire harness plug connector with the left side of the wire harness connection head, and then perform a sliding clamping through the sliding components on the right side of the wire harness plug connector and the sliding components inside the left side of the wire harness connection head. During this process, due to the tension inside the sliding components, the wire harness plug connector will be clamped inside the wire harness connection head, and after the sliding components are pushed in place, the elastic clamping components outside the sliding components will be clamped inside the wire harness connection head. However, there are still certain defects in its device; After the wire harness plug connector and the connection head are connected, there is a gap between the two, and there is no protection mechanism for the existing gap. Once dust enters the wire harness through the gap, it will gradually accumulate on the metal contact parts of the plug connector and the connection head. Over time, an insulating dirt layer will be formed, hindering the smooth transmission of current, resulting in an increase in resistance, and then causing the circuit to heat up. In severe cases, it may even cause a fire.

[0004] Therefore, we propose an automotive wire harness assembly with quick connectors to solve the problems raised above. Summary of the Invention

[0005] The object of the present invention is to provide an automotive wiring harness assembly with a quick connector, so as to solve the problem proposed in the above background technology that there is a gap between the wiring harness plug connector and the connector after connection in the current market, and there is no protection mechanism for the existing gap. Once dust enters the wiring harness through the gap, it will gradually accumulate on the metal contact parts of the plug connector and the connector. Over time, an insulating dirt layer will be formed, hindering the smooth transmission of current, resulting in an increase in resistance, and then causing the circuit to heat up. In severe cases, it may even cause a fire.

[0006] To achieve the above object, the present invention provides the following technical solution: An automotive wiring harness assembly with a quick connector, including a first wiring harness connector, a second wiring harness connector, a clamping groove, a clamping block, an elastic positioning ball, a threaded rod, a limit nut, a bearing seat, an adjusting bolt, a positioning frame, an arc groove, a rectangular groove, a protection frame, a U-shaped groove, a threaded sleeve, a limit frame and a positioning bolt.

A clamping block is installed on the left side of the second wiring harness connector. Elastic positioning balls are installed on both the upper and lower sides inside the clamping groove. Threaded rods are installed on both the upper and lower sides of the first wiring harness connector; Adjusting bolts are installed on both the front and rear sides of the first wiring harness connector through bearing seats, and positioning frames are installed on the adjusting bolts. Arc grooves are opened on both the upper and lower sides of the clamping block, and rectangular grooves are opened on both the front and rear sides of the clamping block. A protection frame is sleeved on the second wiring harness connector, and U-shaped grooves are opened on both the upper and lower sides on the left side of the protection frame.

[0007] Preferably, the clamping block is clamped with the clamping groove, and the clamping block is fixedly connected with the second wiring harness connector.

[0013] Preferably, the positioning frame is clamped with the rectangular groove, and the elastic positioning ball is clamped with the arc groove.

[0014] With the above structural design, the elastic positioning ball is initially positioned when the clamping block is inserted, preventing it from easily coming out; the positioning frame further limits the position, providing double protection for the stability of the connection between the first wire harness connector and the second wire harness connector, greatly improving the reliability of the wire harness connection, and reducing the risk of circuit failures caused by connection loosening.

[0015] Preferably, the protective frame forms a sliding connection structure with both the first wire harness connector and the second wire harness connector.

[0016] With the above structural design, it is convenient for the protective frame to slide on the two wire harness connectors, and can conveniently cover the gap existing when the first wire harness connector and the second wire harness connector are connected, effectively blocking impurities such as dust and water vapor from entering, preventing damage to the circuit caused by the accumulation of impurities, extending the service life of the wire harness assembly, and improving the safety and stability of the automotive electrical system.

[0017] Preferably, a threaded sleeve is installed on the right side of the protective frame, a limiting frame is installed on the second wire harness connector, and a positioning bolt is installed on the limiting frame, and the positioning bolt is threadedly connected with the threaded sleeve.

[0018] With the above structural design, when the protective frame is not needed, it can be moved and fixed by the positioning bolt.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The automotive wire harness assembly with a quick connector: 1. Good protection performance: The design of the protective frame effectively blocks impurities such as dust and water vapor from entering the connection gap of the wire harness connector, avoiding potential safety hazards such as increased resistance, wire heating, and even fire caused by the accumulation of impurities, extending the service life of the wire harness assembly, and improving the safety and stability of the automotive electrical system; 2. Stable and reliable connection: Through the clamping cooperation of the clamping groove and the clamping block, as well as the double positioning structures of the elastic positioning ball and the arc groove, and the positioning frame and the rectangular groove, the connection stability between the first wire harness connector and the second wire harness connector is greatly enhanced, reducing the problem of connection loosening caused by reasons such as vehicle vibration, ensuring the reliability of the automotive circuit connection, and guaranteeing the normal operation of automotive electronic devices; 3. Simple and flexible operation: By adjusting the settings of the adjusting bolt, limit nut, and positioning bolt, the connection and fixation operations of the wire harness connector are relatively simple. Workers do not need to rely on complex tools and can complete the operations through simple rotation and sliding, improving the work efficiency of wire harness installation and maintenance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 6, the present invention provides a technical solution: an automotive wire harness assembly with a quick connector, including a first wire harness connector 1, a second wire harness connector 2, a clamping groove 3, a clamping block 4, an elastic positioning ball 5, a threaded rod 6, a limit nut 7, a bearing seat 8, an adjusting bolt 9, a positioning frame 10, an arc-shaped groove 11, a rectangular groove 12, a protective frame 13, a U-shaped groove 14, a threaded sleeve 15, a limit frame 16 and a positioning bolt 17. A second wire harness connector 2 is arranged on the right side of the first wire harness connector 1. A clamping groove 3 is formed on the right side of the first wire harness connector 1. A clamping block 4 is installed on the left side of the second wire harness connector 2. The clamping block 4 is clamped with the clamping groove 3. The clamping block 4 is fixedly connected with the second wire harness connector 2. When performing wire harness connection operation, the clamping block 4 on the second wire harness connector 2 is aligned with the clamping groove 3 on the right side of the first wire harness connector 1 and inserted. Elastic positioning balls 5 are installed on both the upper and lower sides inside the clamping groove 3. Threaded rods 6 are installed on both the upper and lower sides of the first wire harness connector 1. Limit nuts 7 are installed on the threaded rods 6. The diameter of the threaded rod 6 is smaller than the width of the U-shaped groove 14. After the connection is completed, the protective frame 13 is pushed and slid to the left to cover the connection part of the first wire harness connector 1 and the second wire harness connector 2. At this time, the U-shaped grooves 14 on both the upper and lower sides on the left side of the protective frame 13 are sleeved on the threaded rods 6, and then the limit nuts 7 are rotated to move on the threaded rods 6 and abut against the protective frame 13, thereby fixing the position of the protective frame 13 and preventing it from sliding randomly.

[0024] On both the front and rear sides of the first wire harness connector 1, adjusting bolts 9 are installed through bearing seats 8, and positioning frames 10 are installed on the adjusting bolts 9. The positioning frames 10 penetrate through the front and rear sides of the first wire harness connector 1, and the positioning frames 10 are slidably connected to the first wire harness connector 1. By rotating the adjusting bolts 9, the adjusting bolts 9 will drive the positioning frames 10 to move towards the inside of the first wire harness connector 1, so that the positioning frames 10 slide into the rectangular grooves 12 on the clamping blocks 4, further limiting the clamping blocks 4, enhancing the stability of the connection between the first wire harness connector 1 and the second wire harness connector 2, and preventing loosening of the connection due to vibrations and other factors during vehicle driving. The positioning frames 10 are clamped with the rectangular grooves 12, and the elastic positioning balls 5 are clamped with the arc grooves 11. During the insertion process, the clamping blocks 4 squeeze the elastic positioning balls 5, causing a certain elastic deformation of the elastic positioning balls 5. When the clamping blocks 4 are inserted in place, the elastic positioning balls 5 recover their deformation and snap into the arc grooves 11 to achieve preliminary positioning, preventing the clamping blocks 4 from easily slipping out of the clamping grooves 3. Arc grooves 11 are provided on both the upper and lower sides of the clamping blocks 4, and rectangular grooves 12 are provided on both the front and rear sides of the clamping blocks 4. A protective frame 13 is sleeved on the second wire harness connector 2. The protective frame 13 forms a sliding connection structure with both the first wire harness connector 1 and the second wire harness connector 2. The protective frame 13 can slide on the first wire harness connector 1 and the second wire harness connector 2, facilitating the covering of the gap existing when the first wire harness connector 1 and the second wire harness connector 2 are connected. U-shaped grooves 14 are provided on both the upper and lower sides on the left side of the protective frame 13. A threaded sleeve 15 is installed on the right side of the protective frame 13. A limiting frame 16 is installed on the second wire harness connector 2, and a positioning bolt 17 is installed on the limiting frame 16. The positioning bolt 17 is threadedly connected to the threaded sleeve 15. When the protective frame 13 is not needed, move the protective frame 13 until the threaded sleeve 15 on its right side abuts against the limiting frame 16, and then rotate the positioning bolt 17. The positioning bolt 17 is connected to the threaded sleeve 15, thus facilitating the limiting of the protective frame 13.

[0025] Working principle: When using the automotive wire harness assembly with a quick connector, first, when performing wire harness connection operations, align the clamping blocks 4 on the second wire harness connector 2 with the clamping grooves 3 on the right side of the first wire harness connector 1 and insert them. During the insertion process, the clamping blocks 4 squeeze the elastic positioning balls 5, causing a certain elastic deformation of the elastic positioning balls 5. When the clamping blocks 4 are inserted in place, the elastic positioning balls 5 recover their deformation and snap into the arc grooves 11 to achieve preliminary positioning, preventing the clamping blocks 4 from easily slipping out of the clamping grooves 3. After being initially in place, rotate the adjusting bolts 9. The adjusting bolts 9 will drive the positioning frames 10 to move towards the inside of the first wire harness connector 1, so that the positioning frames 10 slide into the rectangular grooves 12 on the clamping blocks 4, further limiting the clamping blocks 4, enhancing the stability of the connection between the first wire harness connector 1 and the second wire harness connector 2, and preventing loosening of the connection due to vibrations and other factors during vehicle driving.

[0026] After the connection is completed, push the protective frame 13 and slide it to the left so that it covers the connection part of the first wire harness connector 1 and the second wire harness connector 2. At this time, the U-shaped grooves 14 on the upper and lower sides on the left of the protective frame 13 are sleeved on the threaded rod 6, and then rotate the limit nut 7 so that it moves on the threaded rod 6 and abuts against the protective frame 13, thereby fixing the position of the protective frame 13 and preventing it from sliding randomly. Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
