Description

Technical Field

[0001] This utility model relates to an electrical connector, and more particularly to an electrical connector for underwater vehicles. Background Technology

[0002] With the deepening of marine exploration and development activities, the performance and reliability of submersibles, as important underwater operational equipment, are becoming increasingly critical. In the design of submersibles, the electrical connection between the battery and the controller is one of the core components ensuring the normal operation of the entire system. Traditional electrical connection methods often employ direct welding or simple plug-in structures. While these methods can meet basic power transmission requirements, they have some significant shortcomings in practical applications.

[0003] Due to the unique operating environment of underwater vehicles, they often face complex hydrological conditions such as high pressure and corrosive seawater. These factors place higher demands on the protection of electrical connections, and traditional connection methods are insufficient to provide adequate waterproofing and moisture protection, easily leading to short circuits or poor contact. Especially during long-term use, vibration and impact may cause solder joints to break or connectors to loosen, further exacerbating the risk of poor electrical contact.

[0004] Therefore, there is an urgent need to develop an electrical connector for underwater vehicles that reduces the probability of poor electrical contact by optimizing the electrical connection mechanism between the battery and the controller. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an electrical connector for submarines that reduces the probability of poor electrical contact by optimizing the electrical connection mechanism between the battery and the controller.

[0006] An electrical connector for a submersible includes a battery base, battery bodies, a central locking socket, a battery upper socket, a female connector, a control board, and a male connector. The battery base houses four battery bodies for power supply. A central locking socket is provided at the connection point between the battery bodies. A battery upper socket is connected between the tops of the battery bodies. A female connector is installed on the top of the battery upper socket. A control board is installed above the female connector. A male connector is provided at the bottom of the control board and is inserted into the female connector.

[0007] As an improvement to the above solution, a limiting plate is also included, with a ring-shaped limiting plate provided on the male end after the female end and the male end are inserted.

[0008] As an improvement to the above solution, a limiting plate is placed above the female head.

[0009] As an improvement to the above solution, a separator assembly is also included. A separator assembly is provided between the battery mount and the control board. The separator assembly includes an L-shaped retaining plate, a first separator, an isolation seat, a second separator, fastening screws, and threaded sleeves. The inner side of the female connector is provided with an L-shaped retaining plate. The first separator is slidably connected between the L-shaped retaining plates. An isolation seat is symmetrically provided on the top of the first separator. The second separator is placed on top of the isolation seat. A fastening screw is inserted into the second separator. The fastening screw is above the isolation seat. Threaded sleeves are symmetrically provided on the top of the battery mount. The threaded sleeves are below the fastening screws. By screwing the fastening screws through the isolation seat and into the threaded sleeves, the first separator and the second separator can be fixed between the battery mount and the control board.

[0010] As an improvement to the above scheme, the ends of the L-shaped card plate are semi-circular.

[0011] As an improvement to the above solution, the edge of the first partition is provided with the same number of U-shaped grooves as the L-shaped clamping plates. The inner side of the U-shaped groove is provided with a slot between the L-shaped clamping plates. The first partition slides between the L-shaped clamping plates through the slot and is secured to the outside of the female head through the U-shaped groove.

[0012] This invention transmits power to the control board via a female and male connector on the battery body. The female and male connectors enable plug-in electrical connection, which reduces the probability of poor electrical contact between the battery and the controller. The first and second partitions are fixed between the battery holder and the control board to isolate the control board and the battery body, preventing interference between them.

The battery base 1 has four battery slots, and four battery bodies 2 for power supply are installed inside the battery base 1. The central locking connector 3 is provided at the connection point of the battery bodies 2, which covers the connection point of the battery bodies 2 to prevent the connection point of the battery bodies 2 from being exposed and causing accidents. The upper battery mount 4 is connected between the top of the battery bodies 2, covering the upper part of the battery bodies 2 and connecting the battery bodies 2. The female connector 5 is installed on the top of the upper battery mount 4, and the control board 6 is installed above the female connector 5. The male connector 7 is provided at the bottom of the control board 6 and is inserted into the female connector 5. When the submersible is working, the battery bodies 2 transmit power to the control board 6 through the female connector 5 and the male connector 7.

The first partition 92 is slidably connected between the L-shaped retaining plates 91. The edge of the first partition 92 has the same number of U-shaped grooves 93 as the L-shaped retaining plates 91. The inner side of the U-shaped grooves 93 is provided with slots 94 between the L-shaped retaining plates 91. The first partition 92 slides between the L-shaped retaining plates 91 through the slots 94. The first partition 92 is secured to the outside of the female connector 5 via a U-shaped groove 93. A symmetrical isolation seat 95 is provided on the top of the first partition 92. A second partition 96 is placed above the isolation seat 95. A fastening screw 97 is inserted into the second partition 96, which is above the isolation seat 95.
