Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector back cover with a wire clamp. Background Technology

[0002] To meet the practical needs of improving cable reliability and protection levels, cable clamps effectively secure cables, preventing terminal loosening or cable damage caused by vibration or pulling, ensuring the stability of signal and power transmission. At the same time, they enhance the sealing of the interface, resist environmental corrosion such as dust and moisture, and extend the service life of connectors. They are widely used in harsh environments such as automotive, industrial and outdoor equipment.

[0003] Currently, the back cover of connectors with wire clamps on the market is usually a separate plastic or metal part, which is fixed to the tail of the connector by screwing or snapping. The main feature is a rigid wire clamp or plastic wire clamp fixed to the cover.

[0004] For connectors that need to transmit high current, such as fast charging and device power, overheating can lead to connector failure, cable aging, or even safety accidents. Furthermore, the wire clips connected to the back cover are generally fixed and have a limited orientation, requiring the wire to be adjusted to fit the direction of the clip. Therefore, a connector back cover with wire clips is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a connector back cover with a wire clamp, which aims to improve the problem of connectors being prone to overheating in the prior art.

[0011] 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.

[0012] Reference Figures 1-3 The present invention provides an embodiment of a connector back cover with a wire clamp, comprising two housings 1. The two housings 1 serve as the main structure and play a basic role in wrapping and fixing the connector. A wire port 20 is fixedly connected between the two housings 1. The wire port 20 is a channel for the line. The wire port 20 is located at the bottom of the two housings 1. A heat dissipation component is installed at the bottom of the housings 1. A wire clamp component is installed on the outside of the housings 1. The heat dissipation component includes a metal plate 12, which is the main heat conduction and heat dissipation channel. The metal plate 12 is fixedly connected inside the housing 1. Fins 2 are fixedly connected to the bottom of the metal plate 12. The fins 2 greatly increase the heat dissipation area in contact with the air. The fins 2 are located at the bottom of the housing 1 and outside the wire port 20. The fins 2 can directly and efficiently dissipate heat from the root of the line that generates heat when transmitting current, thereby effectively reducing the overall temperature of the connector and improving the stability and service life of the equipment.

[0013] Reference Figure 2 and Figure 3The cable clamp assembly includes a base 13, which securely integrates the cable clamp with the housing 5. The base 13 is fixedly connected to the outside of the housing 1. A damping shaft 18 is rotatably connected to the side of the base 13 away from the housing 1. A base plate 19 is fixedly connected to the side of the damping shaft 18 away from the base 13. A base plate 9 is fixedly connected to the side of the base plate 19 away from the damping shaft 18. The housing 5 is fixedly connected to the outside of the base plate 9. By easily rotating the housing 5 to a suitable angle, and releasing it, the damping shaft 18 will immediately and stably fix it in that position, providing great flexibility while ensuring stability and reliability during use.

[0014] Reference Figures 4-6 One housing 1 has a mounting plate 3 fixedly connected to its outer side, and another housing 1 has a mounting plate 11 fixedly connected to its outer side. Both mounting plates 3 and 11 have bolts 4 installed inside. Bolts 4 ensure that they will not shift or loosen during use, ensuring reliable connection and more stable wiring. A fixing plate 7 is fixedly connected to the outer side of housing 5. Bolts 8 are installed inside both fixing plate 7 and base plate 9. Memory foam 6 is fixedly connected inside housing 5. Memory foam 6 provides cushioning and shock absorption and can accommodate wiring of various sizes. A protective layer 15 is fixedly connected inside housing 1. The protective layer 15 has internal... A rubber ring 14 is fixedly connected to the connector. The rubber ring 14 can prevent dust from entering the interior and make it waterproof. The protective layer 15 can ensure that the internal connector is stable even in a shaking environment. A rubber strip 16 is fixedly connected inside one housing 1. The rubber strip 16 has a dustproof and waterproof effect. A groove 17 is opened inside the other housing 1. The rubber strip 16 and the groove 17 are interlocked to prevent external dust and moisture from entering the interior. A magnet 10 is fixedly connected to the outside of the housing 1. The magnet 10 can easily allow the connector to be temporarily attached to the metal surface for easy operation.

[0015] Working principle: First, the wires at the tail of the connector are passed through the wire port 20, and the connector body is tightly fitted to the inside of the housing 1. Then, the mounting plates 11 and 3 on both sides of the housing 1 are tightly fixed together by bolts 4. The internal protective layer 15 will be tightly fitted to the connector body. The rubber strip 16 will also be embedded in the groove 17 and cooperate with the rubber ring 14 to prevent moisture from entering the inside of the housing 1, making the inside completely sealed. When the internal circuit carries a high-power current that causes the connector to heat up, the heat will be transferred to multiple fins 2 through the bottom metal plate 12, improving the heat dissipation efficiency.

[0016] The base 13 on the outside of the housing 1 is connected to the chassis 19 via the damping pivot 18, which allows the base plate 9 to be adjusted to any angle on the outside of the housing 1. The memory foam 6 inside the housing 5 can accommodate wires of various thicknesses. The wires are passed through the inside of the memory foam 6, and then the fixing plate 7 and the base plate 9 are fixed together by bolt 2 8, which can stably fix the wires inside the memory foam 6. Then, it can be manually adjusted to a suitable angle. The damping pivot 18 can be fixed at any angle. The magnet 10 on the outside of the housing 1 can allow the connector to be directly attached to the surface of metal objects such as equipment and tables.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
