Description

Technical Field

[0001] This utility model relates to the field of waterproof connector technology, specifically a waterproof guillotine-type power connector. Background Technology

[0002] Electric-assisted two-wheelers are a popular mode of transportation abroad, known for their energy efficiency and environmental friendliness. The battery is the core unit of electric assist, especially the lower tube battery, which is widely used. The connector is the carrier for transmitting battery kinetic energy, and among various connector types, the guillotine connector is widely used due to its compatibility with rotation angles. However, in the actual operating conditions of electric-assisted two-wheelers, the connector has the following problems:

[0003] 1. Guillotine connectors are mostly open structures, which results in poor waterproofing when male and female connectors are mated.

[0004] 2. The male connector prongs are exposed without structural protection and are easily damaged.

[0005] 3. Most female connectors on the market are wire-bonded structures, which are connected to the battery BMS protection board via power lines, resulting in higher costs.

[0006] 4. The separate structure of the male connector and mounting base leads to wasted assembly costs. Therefore, to address the above issues, we propose a waterproof guillotine-type power connector. Utility Model Content

[0007] The purpose of this utility model is to provide a waterproof guillotine-type power connector, which solves the problem that most guillotine-type connectors in the background art have an open structure, resulting in poor waterproofing when male and female connectors are mated.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a waterproof guillotine-type power connector, comprising a female connector and an integrated male panel, wherein power sockets are distributed on both sides of the female connector, and a plurality of signal terminals are provided in the middle of the female connector, wherein a male connector is provided at the upper end of the integrated male panel, and a power insert is provided at the upper end of the male connector, and a plurality of signal inserts are provided on the inner side of the power insert.

[0009] Optionally, the female connector is elliptical, and both ends of the female connector are provided with circular cavities, with mounting holes inside the circular cavities.

[0010] Optionally, the female connector is fitted with a waterproof sealing sleeve with a ribbed structure.

[0011] Optionally, the bottom of the female connector is provided with a bottom cover, and the bottom cover is ultrasonically welded to the bottom of the female connector.

[0012] Optionally, the upper surface of the integrated male end panel is provided with a first fitting fulcrum and a second fitting fulcrum, and the first fitting fulcrum and the second fitting fulcrum are arranged in a triangle.

[0013] Optionally, the middle part of the waterproof sealing sleeve is provided with radial waterproof ribs, the bottom of the waterproof sealing sleeve is provided with a second axial sealing rib, and the end face of the waterproof sealing sleeve is provided with a first axial sealing rib.

[0014] Optionally, the power terminals on both sides of the female connector are configured in a "U" shape.

[0015] Optionally, the tail of the signal terminal is in the shape of a letter, and the tail of the signal terminal is provided with a circular solder hole.

[0016] Optionally, the male connector has a plastic guard at the top of the insert terminal.

[0017] Optionally, the male connector's insert terminals are T-shaped with the plastic guard.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application forms a waterproof seal with the bottom axial waterproof ribs at the radial position and the bottom axial waterproof ribs, and forms an axial waterproof seal with the end face sealing ribs and the male end seal of the integrated mounting base, thereby ensuring that the battery and the vehicle frame base are mutually waterproof when they are fitted together.

[0020] The male connector prongs of the integrated mounting base have plastic guards covering the prong terminals for terminal protection. Furthermore, since the male connector and the vehicle frame mounting base are integrally injection molded, the assembly process of the male connector is reduced, saving assembly costs.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a waterproof guillotine-type power connector, including a female connector 1 and an integrated male panel 2. Power sockets 1-2 are distributed on both sides of the female connector 1, and several signal terminals 1-3 are arranged in the middle of the female connector 1. A male connector 2-1 is arranged at the upper end of the integrated male panel 2, and a power insert 2-2 is arranged at the upper end of the male connector 2-1. Several signal inserts 2-3 are arranged inside the power insert 2-2. A radial waterproof rib is provided in the middle portion of the waterproof sealing sleeve 1-4. The bottom of the waterproof sealing sleeve 1-4 is provided with a second axial sealing rib 1-42, and the end face of the waterproof sealing sleeve 1-4 is provided with a first axial sealing rib 1-41. The power terminals 1-2 on both sides of the female connector 1 are set in a "U" shape at the tail. The tail of the signal terminal 1-3 is in the shape of a "1" and the tail of the signal terminal 1-3 is provided with a circular solder hole 1-311. The top of the insert terminal of the male connector 2-1 is provided with a plastic fence 2-11, and the insert terminal of the male connector 2-1 and the plastic fence are in a "T" shape.
