Description

Technical Field

[0001] This utility model relates to the field of mechatronics, and more specifically to a connector and a vehicle including the connector. Background Technology

[0002] In electric two-wheelers, small electric tricycles, and light logistics electric vehicles, the circuit connection system often requires unsealed connectors due to limitations in installation space, heat dissipation requirements, and lightweight design goals for the hub motor. These connectors eliminate the need for additional sealing rings or waterproof housings, fitting the compact assembly environment of the motor compartment while reducing overall structural weight and manufacturing costs. However, as the core power source of the vehicle, the hub motor generates continuous mechanical vibration during operation. Furthermore, when the vehicle travels on bumpy roads such as unpaved urban roads and rural roads, the impact force is directly transmitted to the motor and connecting components through the suspension system, placing far higher demands on the vibration resistance of unsealed connectors than on ordinary automotive components. However, for commonly used unsealed connectors, only a portion of the terminals is fixed. Especially for wires with small diameters, the wiring area of ​​the terminals and the wires connected to them experience significant movement, causing unsealed connectors to only meet lower vibration test standards. This means that under prolonged driving on bumpy roads, unsealed connectors may disconnect due to their poor vibration resistance, leading to vehicle malfunctions.

[0003] Therefore, there is an urgent need to provide a connector with high vibration resistance, simple structure and low cost. Utility Model Content

[0030] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0031] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0032] See Figures 1 to 7 This utility model discloses a connector 1000 and a vehicle including the connector 1000 (not shown in the figure).

[0033] The connector 1000 includes: a housing 100, three terminals 200 electrically connected to three wires 300 respectively, and a reinforcing member 400. However, those skilled in the art should understand that the present invention is not limited thereto, and the number of terminals 200 and wires 300 can be set according to actual needs.

[0034] The housing 100 is provided with a connection channel 110 extending along a first direction D1 (also referred to as the "longitudinal direction"). In this embodiment, the three terminals 200 are a positive terminal, a negative terminal, and a ground terminal, respectively. The three terminals 200 are at least partially fixed in the three connection channels 110, and include a connection end 210 located in the connection channel 110 for electrical connection with a mating terminal (not shown in the figure) (see...). Figure 4 The device includes a terminal 220 for fixing to and electrically connecting to three wires 300 respectively. In this embodiment, the three wires 300 are a positive wire, a negative wire, and a ground wire. These three wires 300 can be fixed to the terminal 220 of a corresponding terminal 200 by any suitable method such as crimping or soldering, and are electrically connected to that terminal 200. The reinforcement 400 is fixed to the housing 100 and is provided with a reinforcement channel 410 extending along the first direction D1 (see [reference]). Figure 5 See also Figures 5 to 7 The reinforcement member 400 is provided with three reinforcement channels 410 and a spacer wall 450 that separates two adjacent reinforcement channels 410. The reinforcement channel 410 is configured to at least partially fix at least one of the wire 300 and the terminal 220 therein in a form-fit manner, such that the terminal 220 and / or the wire 300 is fixed to the housing 100 by the reinforcement member 400, thereby improving the vibration resistance of the connector 1000 in certain application scenarios (e.g., when the vehicle is driven on a bumpy road for a long time or even in the event of an impact), preventing the wire 300 and the terminal 220 from shaking relative to the housing 100 during vehicle vibration, which could lead to failure of the electrical connection between the terminal 200 and the mating terminal and between the wire 300 and the terminal 220, thereby improving the reliability of the connector 1000, reducing the risk of vehicle failure due to deterioration of the electrical performance of the connector 1000, and improving vehicle safety.

[0035] Despite Figures 1 to 7In one embodiment, the terminal 220 of terminal 200 is located outside the connection channel 110 while the connection end 210 is located inside the connection channel 110. However, those skilled in the art should understand that the present invention is not limited thereto. In other embodiments, the terminal 220 may also be located inside the connection channel 110. In this case, the reinforcing channel 410 is configured to at least partially fix the wire 300 therein in a form-fit manner, such that the wire 300 is fixed to the housing 100 by the reinforcing member 400. In this case, the terminal 220 located inside the connection channel 110 is indirectly fixed to the housing 100 by fixing it to the wire 300, and the reinforcing member 400 is only used to fix the wire 300. In another embodiment, the terminal 220 may also be fixed to the connection channel 110 in a form-fit manner or any other suitable manner, such that the terminal 220 is fixed inside the housing 100, and the wire 300 is simultaneously fixed to the terminal 220 inside the housing 100 and inside the reinforcing member 400.

[0036] See Figure 4 and 5 The conductor 300 includes an insulating sheath 310, and the reinforcing channel 410 includes a first reinforcing section 411 configured to form-fit the insulating sheath 310 therein to prevent the conductor 300 from wobbling relative to the housing 100 and the reinforcing member 400. The conductor 300 also includes a conductive core (not shown) extending from the insulating sheath 310 and fixed to the terminal 220. The reinforcing channel 410 also includes a second reinforcing section 412 configured to form-fit at least partially fix the terminal 220 extending from the connection channel 110 therein to prevent the terminal 220 from causing the conductor 300 to wobble relative to the housing 100 and the reinforcing member 400. Although Figure 4 The diagram shows the entire terminal 220 fixed in the second reinforcing section 412. However, those skilled in the art should understand that the present invention is not limited thereto. As long as the terminal 220 does not wobble relative to the housing 100 and the reinforcing member 400, the terminal 220 can also be partially fixed in the second reinforcing section 412.

[0037] Further, see Figure 5 The diameter of the first reinforcing section 411 is larger than that of the second reinforcing section 412, making the entire reinforcing channel 410 convex. However, those skilled in the art should understand that the present invention is not limited thereto. Depending on the different dimensions of the terminal 220 and the insulating sheath 310, the diameter of the first reinforcing section 411 may also be equal to or smaller than the diameter of the second reinforcing section 412.

[0038] See Figures 4 to 7The reinforcement member 400 has an interface 420 at one end facing the housing 100. The interface 420 includes a groove 421 extending circumferentially along the reinforcement member 400 inside the interface 420 and adjacent to the reinforcement channel 410 along the first direction D1. The housing 100 has a first ridge 120 extending circumferentially along the outer side of the housing 100 (see...). Figure 3 The first ridge 120 is configured to be fixed in the groove 421 in a form-fit manner, thereby securing the reinforcement 400 to the housing 100. The arrangement of the first ridge 120 and the groove 421 greatly simplifies the operation of fixing the reinforcement 400 to the housing 100.

[0039] Further, see also Figures 4 to 7 The interface 420 also includes an inwardly radially projecting flange 422 extending circumferentially along the reinforcement 400 and adjacent to the groove 421 along the first direction D1. The housing 100 also has a second ridge 130 extending circumferentially along its outer side and spaced apart from the first ridge 120 (see...). Figure 3 The flange 422 is configured to be fixed between the first ridge 120 and the second ridge 130 in a form-fit manner (see [reference]). Figure 2 This further secures the reinforcement member 400 to the housing 100. The arrangement of the first ridge 120, the second ridge 130, and the flange 422 further simplifies the operation of securing the reinforcement member 400 to the housing 100. See also Figure 4 One end of the terminal 220 abuts against the insulating skin 310, and the other end of the terminal 220 extends along the first direction D1 to the boundary of the groove 421 adjacent to the flange 422. However, those skilled in the art should understand that the present invention is not limited thereto, and the length of the terminal 220 can be set according to actual needs.

[0040] See Figure 2 , 6 7. The reinforcement 400 is configured as a two-part device, comprising a first part 430 and a second part 440 mated together to define the reinforcement channel 410. The first part 430 has a first protrusion 431 on one side along a second direction D2 (also referred to as the "lateral direction") orthogonal to the first direction D1. The second part 440 has a second arm 442 extending toward the first part 430 on the same side as the first protrusion 431. The second arm 442 has a second through hole 4421 at its free end. The first protrusion 431 is configured to be fixed in the second through hole 4421 in a form-fit manner, such that the first part 430 and the second part 440 are fixed together when mated together.

[0041] See also Figure 6 and 7 The first part 430 is provided with a first stop 433 extending toward the first protrusion 431 along the first direction D1 on the same side as the first protrusion 431. The first stop 433 is configured to abut against the second arm 442 after the second arm 442 moves away from the first protrusion 431 along the second direction D2 under the action of external force, so that the first protrusion 431 disengages from the second through hole 4421 to unlock the first part 430 and the second part 440 that are fixed together, so as to prevent the second arm 442 from moving further along the second direction D2, and avoid the second arm 442 from being over-deformed due to the second arm 442 moving further along the second direction D2, and the resulting inability of the second arm 442 to reset or even breakage.

[0042] Further, see Figure 7 The first portion 430 has a first arm 432 extending toward the second portion 440 on the other side along the second direction D2, and the first arm 432 has a first through hole 4321 at its free end. See also Figure 4 and 5 The second part 440 has a second protrusion 441 on the same side as the first arm 432. The second protrusion 441 is configured to be fixed in the first through hole 4321 in a form-fit manner, so that the first part 430 and the second part 440 are fixed together when they are joined together.

[0043] See also Figure 4 and 5 The second portion 440 has a second stop 443 extending toward the second protrusion 441 along the first direction D1 on the same side as the second protrusion 441. The second stop 443 is configured to be located on the first arm 432 (see...). Figure 7 The second protrusion 441 moves away from the second protrusion 441 along the second direction D2, causing the second protrusion 441 to disengage from the first through hole 4321. After the first part 430 and the second part 440 are unlocked and fixed together, they abut against the first arm 432 to prevent the first arm 432 from moving further along the second direction D2. This avoids excessive deformation of the first arm 432 due to further movement of the first arm 432 along the second direction D2, and the resulting inability of the first arm 432 to reset or even breakage.

[0044] See Figure 6 and 7 The first part 430 and the second part 440 have the same structure as each other (see Figure 7The first part 430, after rotating 180° clockwise, is identical to the second part 440. It is then joined and fixed together along a third direction D3 (also referred to as the "vertical direction") orthogonal to the first direction D1 and the second direction D2. This two-part structure of the reinforcement 400 greatly facilitates its installation onto and removal from the housing 100. Since the first part 430 and the second part 440 have identical structures, both parts constituting the reinforcement 400 can be produced using a single mold, significantly reducing the structural complexity and production cost of the reinforcement 400. This is beneficial for the industrialization and widespread application of the reinforcement 400 and the connector 1000.

[0045] See Figure 1 and 5 The reinforcement member 400 is provided with a first observation hole 4111 extending from its outer side along the third direction D3 into the first reinforcement section 411 and a second observation hole 4121 extending from its outer side along the third direction D3 into the second reinforcement section 412. The user can observe through the first observation hole 4111 whether the wire 300 is located in the first reinforcement section 411 and can observe through the second observation hole 4121 whether the terminal 220 is located in the second reinforcement section 412, facilitating the user's visual installation of the terminal 200 and wire 300 in the reinforcement member 400.

[0046] Those skilled in the art will understand that the embodiments described above are exemplary and can be improved upon. The structures described in the various embodiments can be freely combined without causing any conflict in structure or principle.

[0047] After a detailed description of the preferred embodiments of the present invention, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the appended claims, and that the present invention is not limited to the embodiments described in the specification.
