[0032] To enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please refer to Figures 1 to 3 , Figure 1 which is the structural schematic diagram of the connector assembly 1000 provided in the embodiment of the present application; Figure 2 is Figure 1 the front view of Figure 3 is Figure 1 the structural schematic diagram of the connector 100 of the connector assembly 1000 in

[0034] The connector assembly 1000 in this embodiment includes a connector 100. The connector 100 is as shown in Figure 3 . The connector 100 includes a plug 101 and a connection wire harness 102 connected to the plug 101. The connector 100 can be connected to a mating docking device (not shown in the figure). The docking device and the connector 100 are in a male - female mating relationship. Figure 3The plug connector 101 of the connector 100 in [description] has a plug end, which specifically includes a plurality of pins 1012. The pins 1012 can be docked with the docking interface of the docking device to achieve electrical connection. For example, if the connector assembly 1000 is a female plug, the adapted docking device is a male plug. One end of the connecting wire harness 102 of the connector 100 of the connector assembly 1000 is internally connected to the pins 1012 inside the plug connector 101, and the other end of the connecting wire harness 102 can be connected to other electrical devices. The connecting wire harness 102 can include multiple cables 1021, and the multiple cables 1021 can be wrapped in a wire harness sleeve 1022.

[0035] As Figure 1 shown, the connector assembly 1000 in this embodiment further includes a protective sleeve 200. The protective sleeve 200 includes a sleeve head 201 and a sleeve tail 202. The sleeve head 201 wraps the plug connector 101, that is, the entire plug connector 101 is located inside the sleeve head 201. Of course, the sleeve head 201 has an open end to allow the plug end of the plug connector 101 to be exposed so as to achieve electrical connection with the docking device. The sleeve tail 202 wraps at least a part of the connecting wire harness 102, Figure 1 and in [description], the sleeve tail 202 wraps a section where the connecting wire harness 102 is connected to the plug connector 101.

[0036] In addition, the sleeve tail 202 has a corrugated section 2021, and at least a part of the connecting wire harness 102 is located inside the corrugated section 2021. The corrugated section 2021 has the ability to expand and contract in the length direction, so that the corrugated section 2021 has better elasticity and flexibility, and thus has the characteristic of being resistant to bending. It can adapt to the vibration and deformation of the connecting wire harness 102 during use. For example, if the connector assembly 1000 is applied to an automobile, vibrations and deformations are likely to occur during the driving of the automobile. The corrugated section 2021 can improve and even eliminate the influence on the connector 100 caused by vibrations and deformations. In addition, the corrugated shape of the corrugated section 2021 helps to disperse stress and friction, so that it can better adapt to and disperse stress when the connector 100 is bent or twisted, which is beneficial to preventing the protective sleeve 200 from cracking or falling off, and can also increase the anti-wear and anti-tensile capabilities of the connecting wire harness 102, thereby reducing the damage to the connecting wire harness 102 of the plug connector.

[0037] It can be seen that the protective sleeve 200 in this embodiment can protect the plug 101 of the connector 100 and the position where the plug 101 is connected to the connecting wire harness 102, preventing the intrusion of rainwater, dust, etc., thus being protected from external environmental interference, reducing the failure rate of the connector 100, increasing the service life of the connector 100 and other electronic devices, and reducing the maintenance cost. The waterproof and dustproof performance of the connector assembly 1000 under extreme working conditions can also be improved, and it can also not affect the normal use of the connector 100 under extreme working conditions, improving the utilization rate of the connector 100. Moreover, when there is a risk of electric leakage due to multiple pluggings and unpluggings of the connector 100, the protective sleeve 200 can also play a protective role, improving the safety factor. In addition, as described above, due to the setting of the corrugated pipe section 2021, the connecting wire harness 102 of the connector 100 can also be further protected, reducing damage. Moreover, such a protective sleeve 200 and connector 100 are also applicable to the connection of electrical appliances and wire harnesses of various vehicles, and can meet the requirements of different application scenarios.

[0038] Reference may continue to Figure 1 , the connector assembly 1000 in this embodiment further includes a cable tie component 300, and the tail 202 of the protective sleeve is tightened to the connecting wire harness 102 through the cable tie component 300. By tightening with the cable tie component 300, it can prevent the protective sleeve 200 and the connector 100 from separating, and can also prevent the connecting wire harness 102 of the connector 100 from loosening, getting disordered or being damaged. On this basis, the structure of the cable tie component 300 is relatively simple.

[0039] The cable tie component 300 includes a cable tie 302 and a clamping seat 301. The cable tie 302 can be set to have a serrated structure on its surface, and the clamping seat 301 can be provided with a cable tie hole 301a, and the hole wall of the cable tie hole 301a is also provided with a serrated structure. One end of the cable tie 302 is connected to the clamping seat 301, for example, and the other end surrounds the connecting wire harness 102 and then is inserted into the cable tie hole 301a. The serrated structure of the cable tie 302 and the serrated structure of the cable tie hole 301a can form self-locking, that is, the cable tie 302 can be pulled along the tightening direction, but along the loosening direction, the serrated structure of the cable tie 302 and the serrated structure on the hole wall of the cable tie hole 301a will be stuck to each other to form self-locking. In this way, the cable tie component 300 can provide a more firm fixing effect on the connecting wire harness 102 and the protective sleeve 200.

[0040] Specifically, as Figure 2 shown, the tail 202 of the protective sleeve 200 includes an anti-disengagement pipe section 2022. The anti-disengagement pipe section 2022 is connected to the corrugated pipe section 2021, and the corrugated pipe section 2021 is connected to the head 201 of the protective sleeve, that is, the corrugated pipe section 2021 is located between the protective pipe section and the head 201 of the protective sleeve. The outer surface of the anti-disengagement pipe section 2022 may have an annular recess 2022a. Figure 2Compared to the corrugated tube section 2021, the center portion of the anti-detachment tube section 2022 is recessed inward (i.e., recessed toward the connecting harness 102), forming an annular recess 2022a. This allows the cable tie 302 of the cable tie assembly 300 to be embedded within the annular recess 2022a. During use, the cable tie 302 can be wrapped around the annular recess 2022a. When the cable tie 302 is then passed through the cable tie hole 301a and tightened, the cable tie 302 gradually tightens within the annular recess 2022a, preventing the cable tie 302 from easily separating from the protective cover 200. This allows the anti-detachment tube section 2022 and the connecting harness 102 to be more securely fastened together.

[0041] For example, the inner surface of the anti-slip tube section 2022 can also be provided with textures, which can increase the roughness of the inner surface of the anti-slip tube section 2022, thereby further increasing the friction between the anti-slip tube section 2022 and the connecting harness 102, thereby better ensuring the locking of the anti-slip tube section 2022 and the connecting harness 102. The anti-slip tube section 2022 can also be provided with perforations, through which the cable tie 302 can pass, thereby further ensuring the locking effect with the anti-slip tube section 2022 and preventing the cable tie 302 from separating from the protective cover 200. More specifically, the anti-slip tube section 2022 can be provided with radially protruding lugs, and the lugs are provided with perforations, through which the cable tie 302 passes, thereby maintaining connection with the cable tie 302.

[0042] In this embodiment, the holder 301 of the strap component 300 may be provided with a mounting portion 3011. When the connector assembly 1000 is applied to a car, the mounting portion 3011 is used to fix to the car body. In this way, the connector assembly 1000 can be fixed more reliably.

[0043] like Figures 4 to 6 As shown, Figure 4 Schematic diagram of the structure of the connector assembly 1000 in the embodiment of the present application installed on the electrical inlet 2000 from a first viewing angle; Figure 5 for Figure 4 Schematic diagram of the structure under the second viewing angle; Figure 6 for Figure 4 Schematic diagram of the structure from a third-person perspective.

[0044] The connector assembly 1000 can be installed on the electric inlet 2000 of the car. Specifically, the card holder 301 can be installed on the electric inlet 2000. For example, a bracket 2001 (shown in FIG. 2 ) can be provided on the electric inlet 2000. Figure 5 ), the bracket 2001 has a reserved fixing hole (not shown in the figure), and the mounting portion 3011 of the socket 301 can be inserted into the fixing hole to complete the installation and fixation. The bracket 2001 is not limited to being set on the power input 2000, for example, it can be directly set on the vehicle body or on other structures fixed to the vehicle body.

[0045] The protective sleeve 200 in this embodiment can be entirely made of an insulating material, such as a plastic or rubber sleeve. While maintaining insulating properties, the plastic or rubber sleeve also possesses good flexibility to enhance protection and provide deformability. Furthermore, due to its flexibility, the protective sleeve 200 and connector 100 are easily installed and removed. The protective sleeve 200 can also be configured such that its inner surface comprises an insulating layer, meaning that at least the inner surface of the protective sleeve 200 is constructed of an insulating material. This configuration effectively isolates the connector 100 from the external environment, improving the insulation performance of the connector 100 and reducing the risk of leakage and short circuits.

[0046] The protective cover 200 in this embodiment is an integrated structure, that is, the protective cover head 201 and the protective cover tail 202 are an integrated structure. Figure 2 As shown, the cross-sectional size of the sheath head 201 of the protective sheath 200 is larger than the cross-sectional size of the sheath tail 202, which is mainly adapted to Figure 3 In the structure of the connector 100 shown, the cross-sectional dimensions of the plug connector 101 of the connector 100 are relatively large, and the cross-sectional dimensions of the connection harness 102 of the connector 100 are relatively small. The sheath head 201 generally includes a constant diameter portion 2011 and a reduced diameter portion 2012. The tail portion of the plug connector 101 of the connector 100 is tapered toward the connection harness 102, and the reduced diameter portion 2012 of the sheath head 201 corresponds to the tapered tail portion of the plug connector 101.

[0047] When installing the protective cover 200, the connecting wire harness 102 can be passed from the cover head 201 to the cover tail 202 until the plug connector 101 is inserted into the cover head 201. Most of the connecting wire harness 102 is passed outside the protective cover 200, and the section where the connecting wire harness 102 and the plug connector 101 are connected is located in the cover tail 202, which mainly protects the plug connector 101 and the position where the plug connector 101 and the connecting wire harness 102 are connected.

[0048] like Figure 2 As shown, the end surface of the open end of the sheath head 201 can be provided with an elastic gasket 2013, and the elastic gasket 2013 can be integrally provided with the sheath head 201. With this arrangement, when the connector 100 and the matching dock are connected, the elastic gasket 2013 can be in close contact with the corresponding dock, playing a role of sealing protection. In particular, when the connector 100 is plugged and unplugged multiple times and the dock may have a poor connection, which may cause leakage, this arrangement can improve the safety of use.

[0049] Please continue to refer to Figure 2 、 3, the connector 100 in this embodiment is provided with a buckle 1011 for locking with a mating docking connector, and the docking connector is correspondingly provided with a slot. Figure 2 There is a certain gap between the sheath head 201 of the protective sleeve 200 and the plug 101 in Figure 2 . After the connector assembly 1000 is plugged into the mating docking connector, a part of the docking connector will be located in this gap, and the slot of the docking connector and the buckle 1011 will be engaged with each other, thereby completing the locking of the docking connector and the connector assembly 1000 in the plugging direction. When it is necessary to separate the docking connector and the connector assembly 1000, it is necessary to press the sheath head 201 externally. The pressing force is transmitted to the inner side of the protective sleeve 200, thereby acting on the buckle 1011 to unlock the buckle 1011 and the slot, and then the docking connector and the connector assembly 1000 can be disassembled. The setting of the buckle 1011 is beneficial to improving the reliable connection between the docking connector and the connector assembly 1000 and preventing the loosening of their connection due to vibration or other reasons.

[0050] In addition, reference can be continued to Figure 2 and 3 , the outer wall of the connector 100 in this embodiment is provided with a guiding notch or a guiding protrusion 1013 for aligning with a mating docking connector, that is, only when the guiding protrusion 1013 of the connector 100 and the guiding notch of the docking connector are aligned in the plugging direction, or only when the guiding notch of the connector 100 and the guiding protrusion 1013 of the docking connector are aligned in the plugging direction, can the connector 100 and the docking connector be plugged together to ensure that the connector assembly 1000 and the docking connector are reliably connected together in the required orientation. Generally speaking, different types of connectors 100 will also have different sockets due to different shapes and the number of pin feet. It can be seen that such a setting can play a role in preventing misconnection during the plugging of the connector assembly 1000 and the docking connector.

[0051] When the connector assembly 1000 is docked with and disassembled from the corresponding docking connector, the steps are as follows:

[0052] One push: Push the connector assembly 1000 to make the connector assembly 1000 and the mating docking connector be plugged and connected, and the buckle 1011 is in the locked state;

[0053] Two presses: Press the buckle 1011 of the connector assembly 1000 with a finger to release the locked state of the connector 100;

[0054] Three pulls: While pressing the buckle 1011, pull the connector 100 outward to disconnect it from the mating docking connector.

[0055] All these operations can be performed outside the protective sleeve 200, making the installation and disassembly of the connector 100 easier, without the need to rely on complex tools and operations, thereby improving work efficiency.

[0056] An embodiment of the present application further provides an automobile, including the connector assembly 1000 described in any of the above embodiments, which has the same technical effects as the connector assembly 1000 and will not be elaborated herein.

[0057] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
