DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0023] See Figures 1 to 6 , a connector for an automotive wire harness assembly, comprising: A connector body 1, in which a wire hole 11 is formed, and a cable 10 is slidably installed in the wire hole 11; A connection unit 2, slidably connected to the surface of the connector body 1 and communicating with the wire hole 11, for cooperating with the wire hole 11 to realize the rotation of the cable 10; A sealing unit 3, installed on the inner wall of the connector body 1, snap-fitted to the surface of the cable 10, and slidably connected to the surface of the connection unit 2, for cooperating with the connection unit 2 to realize the sealing of the surface of the cable 10; An adjusting unit 4, rotatably connected to the connector body 1 and slidably connected to the connection unit 2, for driving the connection unit 2 to slide on the surface of the connector body 1; A winding unit 5, installed on the side surface of the connector body 1, and a driving unit 6 is installed on the side surface, and the driving unit 6 is used to drive the winding unit 5 to rotate, so as to realize the winding and wrapping of the surface of the cable 10.

[0024] In an embodiment of the present invention, when the adjusting unit 4 is rotated, the connection unit 2 can slide on the surface of the connector body 1 under the action of the adjusting unit 4. When the connection unit 2 communicates with the wire hole 11, two groups of cables 10 are respectively inserted into the wire hole 11 and the connection unit 2. After the adjusting unit 4 is released, the connection unit 2 can slide reversely under the action of the adjusting unit 4, so that the two groups of cables 10 can be fixed under the action of the connection unit 2. The sealing unit 3 can be inflated and expanded in cooperation with the connection unit 2, so that the sealing unit 3 can be in close contact with the surface of the cable 10, improving the sealing performance of the cable 10 in the connector body 1, and making the cable 10 have the advantages of waterproof and dustproof during connection.

[0025] In an embodiment of the present invention, as Figure 1 and Figure 4 shown, the connection unit 2 includes: A sliding frame 21, slidably connected to the surface of the connector body 1, with at least seven groups of clamping holes 22 formed on the surface, and the clamping holes 22 communicate with the wire hole 11; An arc-shaped frame 23, fixed to the inner wall of the wire hole 11, and the surface is slidably connected inside the clamping hole 22; A connecting frame 24, connected to the two side surfaces of the sliding frame 21.

[0026] In this embodiment, when connecting the cable 10, the end of a group of cables 10 is inserted into the wire hole 11, and the end of the other group of cables 10 is inserted into the clamping hole 22 on the surface of the sliding frame 21 until the ends of the two groups of cables 10 come into contact inside the clamping hole 22.

[0027] Activate the adjusting unit 4. The adjusting unit 4 can drive each group of sliding frames 21 to slide outward on the surface of the connector body 1 (in the direction away from the center of the circle of the connector body 1) by connecting with each group of sliding frames 21 respectively. When the sliding frame 21 slides, it can drive the clamping hole 22 to slide synchronously, so that the distance between the inner wall of the clamping hole 22 and the inner wall of the arc-shaped frame 23 will decrease until the inner wall of the clamping hole 22 contacts the surface of the cable 10, enabling the two groups of cables 10 to be clamped and fixed under the action of the inner wall of the clamping hole 22 and the arc-shaped frame 23, thereby improving the stability of the cable 10 inside the connector body 1.

[0028] In one embodiment of the present invention, as Figure 4 and Figure 5 shown, the sealing unit 3 includes: An airbag ring 31, installed on the inner wall of the clamping hole 22; An inflating frame 32, fixed on the surface of the connector body 1, and the sliding frame 21 is slidably connected between the two groups of inflating frames 32; An air chamber 33, opened inside the inflating frame 32, with a piston member 34 slidably connected inside. The numbers of the air chamber 33, the airbag ring 31, the clamping hole 22, and the wire hole 11 are the same; An air tube 321, with one end communicating with the airbag ring 31 and the other end communicating with the inside of the air chamber 33; A sliding rod 35, slidably connected inside the inflating frame 32. The piston member 34 is installed on the surface of the sliding rod 35, and the end of the sliding rod 35 is slidably connected with the surface of the connecting frame 24.

[0029] In this embodiment, when the sliding frame 21 slides outward on the surface of the connector body 1, the sliding frame 21 can drive the connecting frame 24 on its surface to slide synchronously. Since the end of the sliding rod 35 is slidably connected with the connecting frame 24, the sliding rod 35 will slide outward inside the inflating frame 32 under the push of the connecting frame 24. Furthermore, the sliding rod 35 will drive the piston member 34 to slide in the air chamber 33 in the direction away from the center of the circle of the connector body 1 ( Figure 5Sliding upward (above), when the piston member 34 slides upward in the air chamber 33, the space formed between the upper side of the piston member 34 and the air chamber 33 will decrease. Thus, the gas in this space will be pushed by the piston member 34 through the air pipe 321 into the interior of the airbag ring 31, causing the airbag ring 31 to expand, achieving close contact between the airbag ring 31 and the surface of the cable 10, improving the sealing performance of the cable 10 within the connector body 1, and enhancing the waterproof and dustproof properties of the cable 10.

[0030] Further, the lower side ( Figure 5 below) of the air chamber 33 is communicated with the outside through a ventilation pipe. When the piston member 34 slides upward in the air chamber 33, since the lower side of the air chamber 33 is communicated with the outside through the ventilation pipe, the stability of the air pressure within the space formed between the lower side of the piston member 34 and the air chamber 33 is maintained.

[0031] In an embodiment of the present invention, as Figure 3 and Figure 4 shown, the adjusting unit 4 includes: An adjusting rod 41, rotatably connected to the connector body 1, with a runner 42 mounted on its surface; A sliding column 43, fixed to the side of the sliding frame 21; An inclined frame 44, mounted on the surface of the runner 42, and each group of sliding columns 43 is slidably connected to the side of the corresponding inclined frame 44; An elastic member 45, connected between the end of the sliding frame 21 and the inner wall of the connector body 1.

[0032] In this embodiment, when the adjusting rod 41 is rotated clockwise (in the clockwise direction as shown in 3), the adjusting rod 41 can drive the inclined frame 44 to rotate synchronously through the runner 42. Since the sliding connection exists between the side of the inclined frame 44 and the sliding column 43, the sliding column 43 will drive the sliding frame 21 to slide inward (towards the center of the connector body 1) on the surface of the connector body 1 under the push of the inclined frame 44. When the sliding frame 21 slides, it can drive the clamping hole 22 to slide synchronously, making the clamping hole 22 and the wire hole 11 completely communicate. At the same time, when the sliding frame 21 slides, it can stretch the elastic member 45 at its end.

[0033] Since the clamping hole 22 and the wire hole 11 are completely communicated at this time, two groups of cables 10 can be respectively inserted into the wire hole 11 and the clamping hole 22 through both sides of the connector body 1 until the ends of the two groups of cables 10 contact inside the clamping hole 22.

[0034] Release the adjusting rod 41, so that each sliding frame 21 will slide on the surface of the connector body 1 in the direction away from the center of the connector body 1 under the elastic force of the corresponding elastic member 45, so that the two groups of cables 10 can be clamped and fixed under the action of the inner wall of the clamping hole 22 and the arc-shaped frame 23, improving the stability of the cable 10 in the connector body 1. The elastic member 45 can be a spring or elastic rubber, which is convenient for pulling the sliding frame 21 to slide outward on the surface of the connector body 1.

[0035] When the sliding frame 21 slides outward on the surface of the connector body 1, the sliding frame 21 can drive the connecting frame 24 to slide synchronously. The sliding rod 35 will slide outward in the inflating frame 32 under the push of the connecting frame 24. Furthermore, the sliding rod 35 will drive the piston member 34 to slide in the air chamber 33 in the direction away from the center of the connector body 1, causing the airbag ring 31 to expand, improving the sealing performance of the cable 10 in the connector body 1.

[0036] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the winding unit 5 includes: A support 51, installed on the side of the connector body 1; A gear ring 52, slidably connected inside the support 51, and an opening 521 is provided on the gear ring 52; A winding roller 53, fixed on the side of the gear ring 52, and at least two groups of winding rollers 53 are installed.

[0037] In this embodiment, when it is necessary to tighten the cable 10, after passing multiple groups of cables 10 through the opening 521 and into the inside of the gear ring 52 in sequence, winding tapes (or winding films) are respectively installed on the two winding rollers 53, and the ends of the winding tapes (or winding films) are fixed on the surface of the cable 10.

[0038] Start the driving unit 6. The driving unit 6 can drive the gear ring 52 to rotate inside the support 51. During the rotation of the gear ring 52, the winding tapes (or winding films) can be driven to rotate synchronously by the two winding rollers 53, so that the winding tapes (or winding films) on the surfaces of the two winding rollers 53 can wind the surfaces of multiple groups of cables 10, preventing the multiple groups of cables 10 from being disorderly and loose together. And by pulling the cable 10, the two winding tapes (or winding films) can continuously wind the surface of the cable 10, which has the advantage of being more efficient compared with manual winding.

[0039] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the driving unit 6 includes: A driving member 61, installed on the side of the support 51; The drive shaft 62 is rotatably connected within the support 51, and there are two sets of drive shafts 62 installed. One end of one set of drive shafts 62 is connected to the output end of the driving member 61. Gears are installed on the surfaces of both sets of drive shafts 62, and both sets of the gears are meshed with the gear ring 52; The transmission belt 63 is connected to the end surfaces of both sets of drive shafts 62.

[0040] In this embodiment, when the driving member 61 is turned on, the output end of the driving member 61 can drive one set of drive shafts 62 connected thereto to rotate within the support 51. This set of drive shafts 62 can drive the other set of drive shafts 62 to rotate through the transmission belt 63. Thus, both sets of drive shafts 62 can drive the gears on their surfaces to rotate synchronously. Since both sets of gears are meshed with the gear ring 52, the gear ring 52 will rotate within the support 51 under the action of both sets of gears.

[0041] Because an opening 521 is formed on the gear ring 52, when the opening 521 rotates to the surface of one set of gears, since the opening 521 cannot continue to be driven under the action of this set of gears, the gear ring 52 will continue to be driven under the action of the other set of gears at this time, improving the continuity of the rotation of the gear ring 52 within the support 51.

[0042] The driving member 61 can be a motor or a pneumatic motor, as long as it is convenient to drive the drive shaft 62 to rotate stably within the support 51.

[0043] The working principle of the present invention is: Rotate the adjusting rod 41 clockwise. The adjusting rod 41 can drive the inclined frame 44 to rotate synchronously through the runner 42. The sliding column 43 will drive the sliding frame 21 to slide inwards on the surface of the connector body 1 under the push of the inclined frame 44. When the sliding frame 21 slides, it can drive the clamping hole 22 to slide synchronously. When the clamping hole 22 and the wire hole 11 are completely communicated, the two sets of cables 10 are respectively inserted into the wire hole 11 and the clamping hole 22 from both sides of the connector body 1 until the ends of the two sets of cables 10 contact inside the clamping hole 22.

[0044] Release the adjusting rod 41. Thus, each sliding frame 21 will slide away from the center of the connector body 1 on the surface of the connector body 1 under the elastic force of the corresponding elastic member 45, so that the two sets of cables 10 can be clamped and fixed under the action of the inner wall of the clamping hole 22 and the arc-shaped frame 23, improving the stability of the cables 10 within the connector body 1.

[0045] When the sliding carriage 21 slides outwards on the surface of the connector body 1, the sliding carriage 21 can drive the connecting frame 24 to slide synchronously. The sliding rod 35 will slide outwards in the inflating frame 32 under the push of the connecting frame 24. Further, the sliding rod 35 will drive the piston member 34 to slide in the air chamber 33 away from the center of the connector body 1, so that the airbag ring 31 expands, improving the sealing performance of the cable 10 in the connector body 1 and enhancing the waterproof and dustproof performance of the cable 10.

[0046] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection, an electrical connection or a connection capable of mutual communication; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
