[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-4 The utility model discloses an easy-to-produce banana plug connector structure, including a banana plug 1, the banana plug 1 including a plug body 11 and a copper tube terminal 2, the bottom of the plug body 11 is provided with a circle of plug springs 12, the bottom of the plug body 11 is provided with a plug pin 13, the copper tube terminal 2 is sleeved on the plug pin 13, and the bottom of the copper tube terminal 2 is provided with a wire pressing groove 21 for crimping the wire.
[0022] Specifically, a first pressing ear 22 and a second pressing ear 23 are provided on both sides of the wire crimping groove 21. The wire is placed inside the wire crimping groove 21, and the first pressing ear 22 and the second pressing ear 23 are bent and pressed against the wire using crimping pliers to fix the wire. There is no need to use welding equipment, and the working environment is safer. At the same time, it also avoids the problem of wire deformation and wire conductor melting during high-temperature welding, thereby increasing the service life of the wire.
[0023] Specifically, a plurality of bevel teeth 24 are provided on one side of the first pressing ear 22 and the second pressing ear 23. The setting of the bevel teeth 24 can hook the wire to further prevent it from falling off, and further ensure the stability of the wire after crimping.
[0024] Specifically, a threaded portion 25 is provided at the top of the copper tube terminal 2, and a threaded groove 14 is provided at the bottom of the plug body 11 for threaded sleeve engagement with the threaded portion 25. The copper tube terminal 2 and the plug body 11 are connected and fixed by threaded sleeve engagement. During the plugging and unplugging action, the copper tube terminal 2 will not be separated from the plug pin 13, and the connection is more stable.
[0025] Specifically, the top of the copper tube terminal 2 is provided with a flare 26 , and the bottom end of the plug pin 13 is provided with a tapered surface. The cooperation between the tapered surface and the flare 26 facilitates the insertion of the plug pin 13 into the interior of the copper tube terminal 2 .
[0026] Specifically, a plurality of connection grooves 27 are provided inside the copper tube terminal 2 , and a terminal spring piece 28 is bent at the top of the inner wall of the connection groove 27 . The provision of the terminal spring piece 28 ensures the contact area between the plug pin 13 and the copper tube terminal 2 .
[0027] Specifically, a spring 29 is provided inside the copper tube terminal 2. When the copper tube terminal 2 is threadedly connected to the plug body 11, the spring 29 is compressed and continuously contacts the end of the plug pin 13. This design can reduce the situation where the copper tube terminal 2 rotates and becomes loose from the plug body 11, and the connection is more stable.
[0028] In summary, the banana plug connector structure, which is easy to produce, is crimped with the wire through the copper tube terminal 2, so the wire will not melt, has a longer service life, and has a significantly improved tensile strength compared to a direct welding structure.
