Description
Technical Field
[0001] This utility model relates to the field of wire harness connector technology, specifically to a wire harness mounting connector for electric vehicles. Background Technology
[0002] Electric vehicles use wiring harness connectors to connect key components of electrical wiring harnesses between different systems, such as the motor control system, battery management system, and charging system, to ensure stable electrical connections between these systems and guarantee normal vehicle operation.
[0003] The wire harness connector consists of a male and a female terminal. The wire harness is connected to the male terminal, and then the male terminal is inserted into the female terminal to achieve an electrical connection. During the connection process, in order to ensure the firmness of the connection between the male and female terminals, plastic clips are used to limit the connection between the male and female terminals. The use of plastic clips mainly relies on their own elastic restoring force to achieve connection limiting and release. Although this improves the convenience of use, the clips are often damaged due to excessive force. Moreover, the clips only provide one-way limiting, making it difficult to maintain the stability of the connection between the male and female terminals when the electric vehicle is traveling on bumps.
[0004] Therefore, there is an urgent need for a wiring harness mounting connector for electric vehicles to solve the above problems. Utility Model Content

[0006] The fixing component includes a mounting hole formed on the side wall of the mounting sleeve, a fixing plate slidably connected to the mounting hole, an annular fixing groove formed on the side wall of the female end, the annular fixing groove being matched with the fixing plate, and a driving component for driving the fixing plate and a reset component for resetting after driving.
[0007] The fixing plate has a first inclined surface on the side near the mother end.
[0008] Multiple fixing components are provided, and each fixing component is arranged at equal intervals.
[0009] The reset assembly includes connecting plates fixedly connected to two opposite side walls of the fixing plate. Reset tubes are fixedly connected to the two connecting plates near the mounting sleeve. Reset rods are slidably connected to the two reset tubes. One end of each reset rod is connected to the mounting sleeve, and the other end of each reset rod is located inside the reset tube and fixedly connected to a reset plate. Springs are sleeved on the inner side walls of the two reset rods inside the reset tubes. The two ends of each spring are respectively connected to the reset plate and the inner wall of the reset tube.
[0010] The drive assembly includes a drive sleeve fitted onto the male end sidewall. Multiple drive plates are fixedly connected to the side of the drive sleeve near each fixed plate. Each fixed plate has a second inclined surface on the side near the drive plate, and each second inclined surface is arranged opposite to the drive plate.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Example 1
[0023] Please see Figures 1-6 The figure shows a vehicle wiring harness mounting connector for an electric vehicle, including a male end 101 and a female end 102. Wiring harnesses are connected to the sides of the male end 101 and the female end 102 that are far apart from each other. The figure also includes a mounting sleeve 3 disposed on the side of the male end 101 near the female end 102. The mounting sleeve 3 is provided with a fixing component for connecting and fixing the female end 102.
[0024] The fixing component includes a mounting hole 202 formed on the side wall of the mounting sleeve 3, a fixing plate 203 slidably connected to the mounting hole 202, an annular fixing groove 204 formed on the side wall of the female end 102, the annular fixing groove 204 being matched with the fixing plate 203, the male end 101 being provided with a driving component for driving the fixing plate 203 and a reset component for resetting after driving, and a first inclined surface 205 formed on the side of the fixing plate 203 near the female end 102;
[0025] It should be noted that, through the setting of the fixing components, with the cooperation of the reset component and the drive component, while ensuring the insertion limit and easy disassembly of the male end 101 and the female end 102, the fixing components are less likely to be damaged or deformed during use compared to conventional buckle locking. At the same time, multiple fixing components set at equal intervals provide uniform and multi-directional clamping force at the connection between the male end 101 and the female end 102, thereby improving the stability of the connection between the male end 101 and the female end 102 when the electric vehicle is traveling on bumps.
[0026] It is worth noting that the electric vehicle wiring harness connector is a key component in the electric vehicle's electrical system, used to connect various electrical devices and lines to ensure reliable transmission of electrical energy and signals. It acts like a transportation hub, tightly connecting numerous components such as the battery, motor, controller, and sensors, enabling the electric vehicle to operate normally. When the male terminal 101 and female terminal 102 are plugged into each other, current can be transmitted from one wiring harness to another through pins and sockets. The same applies to signal transmission, except that signal current is usually smaller, emphasizing connection stability and anti-interference capabilities. For example, in the connection between the electric vehicle's sensors and controller, weak signals are transmitted accurately through the connector to ensure the controller can accurately control the vehicle's operating status based on sensor feedback. As this is existing technology, it will not be elaborated upon further here.
[0027] Please see Figures 1-4 The diagram shows multiple fixed components, which are arranged at equal intervals.
[0028] It should be noted that multiple equally spaced fixing components provide uniform and multidirectional clamping force at the connection between the male end 101 and the female end 102, thereby improving the stability of the connection between the male end 101 and the female end 102 when the electric vehicle is traveling on bumps.
[0029] Please see Figure 5 The reset assembly shown in the figure includes connecting plates 401 fixedly connected to the two opposite side walls of the fixing plate 203. Reset tubes 402 are fixedly connected to the side of the two connecting plates 401 near the mounting sleeve 3. Reset rods 403 are slidably connected to the two reset tubes 402. One end of the two reset rods 403 is connected to the mounting sleeve 3. The other end of the two reset rods 403 is located inside the reset tubes 402 and is fixedly connected to a reset plate 404. Springs 405 are sleeved on the inner side wall of the two reset rods 403 inside the reset tubes 402. The two ends of the two springs 405 are respectively connected to the reset plate 404 and the inner wall of the reset tube 402.
[0030] It should be noted here that the reset component is used to guide and limit the movement of the fixed plate 203.
[0031] Working principle: When connecting electrical wiring harnesses between different systems of an electric vehicle, male end 101 and female end 102 are first pre-installed at the connection ends of the two wiring harnesses to be connected. Then, male end 101 and female end 102 are pushed to move closer to each other. During the process of male end 101 and female end 102 being plugged into each other, the side wall of female end 102 will abut against multiple fixing plates 203 on the side wall of mounting sleeve 3. Then, under the interaction force of the first inclined surface 205 on each fixing plate 203 and the guiding action of the reset component, each fixing plate 203 is pushed away from female end 102.
[0032] As the male end 101 and the female end 102 are continuously inserted into each other, when the male end 101 and the female end 102 are in place, each fixing plate 203 will engage with the annular fixing groove 204 on the side wall of the female end 102. Then, under the elastic action of the reset component, each fixing plate 203 is pushed into the annular fixing groove 204 and abuts against the bottom wall of the annular fixing groove 204. Thus, under the abutting action of each fixing plate 203, the connection and fixation of the male end 101 and the female end 102 after insertion are achieved. This ensures the convenience of the insertion limit of the male end 101 and the female end 102, and reduces the probability of damage or deformation of the fixing components during use compared with conventional buckle locking. At the same time, multiple fixing components arranged at equal intervals provide uniform and multi-directional abutting force at the connection between the male end 101 and the female end 102, thereby improving the stability of the connection between the male end 101 and the female end 102 when the electric vehicle is traveling on bumps.
[0033] Example 2
[0034] Please see Figure 4 and Figure 5 This embodiment further illustrates Example 1. The driving assembly shown in the figure includes a driving sleeve 501 sleeved on the side wall of the male end 101. A plurality of driving plates 502 are fixedly connected to the side of the driving sleeve 501 near each fixed plate 203. A second inclined surface 503 is provided on the side of each fixed plate 203 near the driving plate 502. Each second inclined surface 503 is disposed opposite to the driving plate 502, and the end of each driving plate 502 away from the driving sleeve 501 is slidably connected to the second inclined surface 503.
[0035] It should be noted that when it is necessary to release the connection between the male end 101 and the female end 102, the drive sleeve 501 can be pushed closer to the female end 102, thereby causing each drive plate 502 to slide on the second inclined surface 503 on the side wall of each fixed plate 203. Under the interaction force between each drive plate 502 and the second inclined surface 503 and the guiding action of the reset component, each fixed plate 203 is pushed away from the female end 102, thereby causing each fixed plate 203 to move out of the annular fixed groove 204. At this time, the connection between the male end 101 and the female end 102 is released. The electrical connection between the two can be released by moving the male end 101 and the female end 102 away from each other.
[0036] Example 3
[0037] Please see Figure 4 This embodiment is a further explanation of other embodiments. In the figure, the male end 101 is fixedly connected to the side wall of the sleeve 6, and the sleeve 6 is located on the side of the drive sleeve 501 away from the mounting sleeve 3.
[0038] It should be noted here that the setting of the retaining sleeve 6 is used to limit the position of the drive sleeve 501, so as to prevent the drive sleeve 501 from being in an excessive sliding state on the side wall of the male end 101.
[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
