Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a connector tail protection component, a connector, a circuit system, and a vehicle. Background Technology

[0002] With the advent of the Internet of Vehicles era and the popularization of intelligent driving, the electrical systems used in vehicles are becoming increasingly complex. Based on their operating voltage, electrical connectors can be divided into low-voltage connectors and high-voltage connectors. Low-voltage connectors are used to transmit low-voltage current and signals, and are therefore commonly used to connect battery management systems (BMS), air conditioning systems, and lighting. When low-voltage connectors are used in battery management systems, due to their low position, a plastic sheath is typically used to protect the connector's tail end to prevent water from splashing onto it when the vehicle is wading through water. However, the plastic sheath restricts the routing of the wiring harness to some extent, resulting in low versatility. This necessitates the selection of different plastic sheaths for different wiring harness routes, indirectly increasing the cost of use.

[0003] Therefore, a wire harness passing rubber component is proposed in the related technology. The wire harness passing rubber component has a rubber component body and a corrugated tube is threadedly connected to the rubber component body. By setting the corrugated tube, the wire harness passing rubber component can be used for wire harnesses with different directions. However, the gap between the corrugated tube and the wire harness cannot be completely eliminated by laying, and there is still a possibility of water leakage, which in turn significantly increases the risk of vehicles wading through water.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] This invention provides a connector comprising a connector body and a connector tail protector. The connector body includes a male and a female connector, which are mated together to achieve electrical connection and / or data transmission. It is understood that one of the male and female connectors is connected to a device via a wiring harness, while the other is integrated into another device. These two devices may include, but are not limited to, two devices in a vehicle's electrical system requiring electrical or signal connection; for example, one device may be a battery pack, and the other a lamp or battery control unit. Of course, the connector can also be used for electrical connections between two devices that may be exposed to water or in humid environments. The connector tail protector is fitted onto the male or female connector connected to the wiring harness to prevent water from entering the connector body. The following description uses the example of the connector tail protector being fitted onto the female connector connected to the wiring harness to illustrate the specific structure of the connector tail protector.

[0030] refer to Figures 1-4 As shown, the connector tail protection component includes a protective body 9, a bellows 1, and a sealing component 2. The protective body 9 is fixedly sleeved on the female connector and can abut against the device where the male connector is located, such as a battery pack. The bellows 1 is connected to the protective body 9 so that the wire harness connected to the female connector can pass through. The sealing component 2 is connected to the end of the bellows 1 away from the protective body 9 and is interference-fitted with the wire harness.

[0031] The aforementioned connector tail protection component, by incorporating a corrugated tube 1, allows the connector tail protection component to extend or bend to a certain extent, thereby adapting to various wire harness arrangements, achieving high versatility, and indirectly reducing usage costs; moreover, the sealing component improves the sealing performance between the connector tail protection component and the wire harness, thereby enhancing the waterproof performance of the entire connector tail protection component and the connector.

[0032] Specifically, the sealing component 2 includes a limiting sleeve and a cement-resistant layer. The limiting sleeve is a cylindrical structure with an inner diameter not exceeding the minimum inner diameter of the corrugated pipe 1. The cement-resistant layer is arranged around the inner wall of the limiting sleeve and is interference-fitted with the wire harness. The cement-resistant layer has high tensile strength and good water and weather resistance. Compared with directly filling the corrugated pipe 1 with the cement-resistant layer, the limiting sleeve reduces the amount of cement-resistant layer used to form the cement-resistant layer, thus reducing manufacturing costs.

[0033] In this embodiment, the length of the corrugated tube 1 can be adjusted according to the length of the end where the wire harness is connected to the female connector. Furthermore, in order to adapt to the shape of the end where the wire harness is connected to the female connector, the cross-sectional area of ​​the corrugated tube 1 gradually decreases from the end connected to the protective body 9 to the other end.

[0034] Optionally, the protective body 9, the corrugated pipe 1, and the limiting sleeve are integrally injection-molded rubber parts, which can utilize their own elasticity to compress the wiring harness and further improve the waterproof effect. In order to fully contact the battery pack and improve the waterproof effect, the protective body 9 is provided with a tapered opening that gradually widens from the end connected to the corrugated pipe 1 to the end away from the corrugated pipe 1.

[0035] refer to Figure 1 As shown, to improve the structural strength of the connector tail protection component, a reinforcing rib 3 is provided on the protective body 9. The reinforcing rib 3 extends axially along the outer wall of the protective body 9. The reinforcing rib 3 also reduces the deformation of the protective body 9 when the connector tail protection component is assembled with the connector body, facilitating overall installation. Specifically, multiple reinforcing ribs 3 are provided circumferentially on the protective body 9, and any reinforcing rib 3 extends from one end of the protective body 9 connected to the bellows 1 to the other end.

[0036] refer to Figure 3 As shown, the protective body 9 is provided with annular waterproof ribs 4 inside. At least two waterproof ribs 4 are arranged at intervals along the axial direction of the corrugated pipe 1. The waterproof ribs 4 abut against the outer wall of the female head to further prevent water from flowing from one end of the corrugated pipe 1 to the connector body.

[0037] When a vehicle is driving through water, the wiring harness is easily impacted by water, causing the connector tail protector to detach from the female connector. Therefore, the protective body 9 has a limiting protrusion 7 inside that mates with a groove on the connector body. The limiting protrusion 7 conforms to the shape of the groove and is engaged within it, thus preventing the connector tail protector from detaching from the female connector. Understandably, the limiting protrusion 7 also improves the installation accuracy of the connector tail protector when it is installed on the connector body, ensuring that the connector tail protector is properly installed. It should be emphasized that the limiting protrusion 7 is located at the end of the waterproof rib 4 furthest from the corrugated pipe 1.

[0038] refer to Figure 4 As shown, the protective body 9 is also provided with a foolproof guide structure 5 to prevent incorrect installation when mounted on the connector body. Specifically, the guide structure 5 is a conformal insertion port on the protective body 9 that follows the shape of the connector body, through which the connector body is inserted into the protective body 9.

[0039] When external equipment is submerged in water for an extended period, the sealing component 2 may fail, inevitably leading to water accumulation inside the connector's tail protective component. To ensure timely drainage of water from the protective body 9 and prevent water buildup at the tail of the connector, a drain outlet 6 is provided on the protective body 9. Specifically, the drain outlet 6 is located at the bottom of the protective body 9, and is positioned on the side of the waterproof rib 4 near the corrugated pipe 1, preventing water entering the protective body 9 through the drain outlet 6 from flowing towards the connection between the male and female connectors. It is understood that because the drain outlet 6 is located at the bottom of the protective body 9, even if water enters the protective body 9 through the drain outlet 6, it will be promptly drained from the drain outlet 6 after the vehicle passes through the accumulated water.

[0040] Continue to refer to Figure 3 As shown, the connector tail protection also includes mounting ears 8. Multiple mounting ears 8 are circumferentially spaced on the outer wall of the protective body 9, and protrude from the protective body 9. After the male and female connectors of the connector body are inserted and mated, external force is applied to the protective body 9 through the mounting ears 8, causing the protective body 9 to be fitted onto the male and female connectors. Specifically, four mounting ears 8 are provided.

[0041] This invention also proposes a circuit system and a vehicle. The circuit system includes two devices and the aforementioned connector, with the two devices electrically connected via the connector. The vehicle includes the aforementioned circuit system, and vehicles using this circuit system exhibit high water wading safety performance.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
