[0001] The utility model relates to the technical field of soft copper connection, in particular to an anti-corrosion soft copper connector. Background Technique

[0002] The copper busbar soft connection and the tinned copper braided wire soft connection are applicable to various high-voltage electrical appliances, vacuum electrical appliances, mine explosion-proof switches, and related products such as automobiles and locomotives for soft connection. They are made of bare copper wire or tinned copper braided wire (stranded wire) by cold pressing. The butt joint surface of the copper busbar soft connection is welded and formed at one time by molecular diffusion welding technology. The product has good quality, strong conductivity, large current-carrying capacity, small resistance value, and is durable, etc.

[0003] During the use of the existing soft copper connectors, in order to make the soft copper connectors have good corrosion resistance, a protective sleeve is wrapped outside the soft copper connectors. However, when the soft copper connectors are bent, the protective sleeve will shrink or warp at its port due to the bending, which may cause the connection between the soft copper braided wire and the connecting plate to be exposed and easily corroded.

Connecting plates 2 are fixedly welded to both ends of the flexible copper braid 1. A protective sleeve 3 is sleeved outside the flexible copper braid 1 and the connecting plates 2. It also includes a sleeve 4 fixedly embedded in the connecting plate 2; a positioning cover plate 5 for preventing displacement of the port of the protective sleeve 3. Two symmetrically distributed positioning cover plates 5 are installed outside the connecting plate 2.

[0022] Please refer to Figure 2 . A plurality of pressing teeth 7 distributed in an array are fixedly arranged on the side of the positioning cover plate 5 close to the connecting plate 2. The shape of the pressing teeth 7 is conical, and the connection method between the pressing teeth 7 and the protective sleeve 3 is movable plug connection. Through holes two 8 equal in number to the pressing teeth 7 are formed in the connecting plate 2 at positions corresponding to the plurality of pressing teeth 7. The through holes two 8 facilitate the connecting plate 2 to avoid the pressing teeth 7.

[0023] Please refer to Figure 2 . A positioning pin 9 with symmetrically distributed sides is fixedly welded to the lower end of the positioning cover plate 5. The positioning cover plate 5 and the connecting plate 2 can squeeze the protective sleeve 3, and the positioning pin 9 is close to the end of the positioning cover plate 5 away from the protective sleeve 3.

[0024] The working principle of preventing the port of the protective sleeve from shrinking: After the protective sleeve 3 is sleeved outside the flexible copper braid 1 and the connecting plates 2, the operator fixes the positioning cover plate 5 outside the connecting plate 2. A plurality of pressing teeth 7 on the side of the positioning cover plate 5 close to the connecting plate 2 will press on the protective sleeve 3, so that the positioning cover plate 5 can position the port of the protective sleeve 3 through the plurality of pressing teeth 7. When the flexible copper braid 1 is bent, shrinkage at the port of the protective sleeve 3 can be avoided, preventing the connection between the flexible copper braid 1 and the connecting plate 2 from being exposed, and making the protective effect of the protective sleeve 3 on the flexible copper connector better.

[0025] Embodiment Two

[0026] Please refer to Figure 3 . This embodiment further illustrates Embodiment One. Two symmetrically distributed positioning holes 10 are formed at the end of the connecting plate 2 away from the flexible copper braid 1. The cross-sectional shapes of the positioning pin 9 and the positioning holes 10 are both circular. The positioning pin 9 is connected to the connecting plate 2 through the positioning holes 10 by plugging and unplugging. Inserting the positioning pin 9 into the positioning holes 10 facilitates the quick alignment of the positioning cover plate 5 and the connecting plate 2. The positioning cover plate 5 and the connecting plate 2 are made of the same material.

[0027] In this embodiment: When installing the positioning cover plate 5, inserting the positioning pin 9 on the side of the positioning cover plate 5 close to the connecting plate 2 into the positioning holes 10 on the connecting plate 2 can quickly align the positioning cover plate 5 and the connecting plate 2, facilitating the assembly of the positioning cover plate 5 and the connecting plate 2.

[0030] In this embodiment: After aligning the two positioning cover plates 5 through the positioning pins 9 and the positioning holes 10, the outer part of the sleeve 4 located outside the positioning cover plate 5 is squeezed by two expansion rods distributed up and down. After the port of the sleeve 4 is squeezed by the expansion rods, it will break and open and press on the positioning cover plate 5, which is not only beneficial to fixing the positioning cover plate 5 and the connecting plate 2, but also beneficial to the connecting plate 2 to connect wires through the sleeve 4.
