DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1

[0023] In one embodiment, Figure 1-Figure 3As shown, an anti-loosening connection terminal includes a first protective shell 101 and a second protective shell 201, wherein a first electric wire 104 is provided at one end of the first protective shell 101, a first protective sleeve 103 is provided at the connection between the first electric wire 104 and the first protective shell 101, a connector 102 is provided at the other end of the first protective shell 101, a second electric wire 203 is provided at one end of the second protective shell 201, a second protective sleeve 202 is provided at the connection between the second electric wire 203 and the second protective shell 201, the second protective sleeve 202 is rotatably connected to the second protective shell 201, a limiting mechanism is provided on the second protective sleeve 202 to prevent the second protective shell 201 from rotating, so as to prevent the second protective shell 201 from rotating and affecting the connection, and a thread is provided at the other end of the second protective shell 201 for conveniently cooperating with the thread of the connector 102, so as to facilitate the first protective shell 101 and the second protective shell 201 to be screwed and fixed.

[0024] A female connector 105 is provided in the connector 102, and the female connector 105 is electrically connected to the first wire 104. A male connector 204 is provided in the second protective shell 201, and the male connector 204 is electrically connected to the second wire 203. The female connector 105 can be plugged in and matched with the male connector 204 to realize information transmission.

[0025] The limiting mechanism includes a fixed plate 302, which is fixedly arranged on the second protective sleeve 202. A spring 304 is fixedly arranged on the side of the fixed plate 302 close to the second protective shell 201. The elastic force of the spring 304 drives the movable plate 301 to approach the second protective shell 201, so as to facilitate the cooperation between the plug-in rod 303 and the sliding groove. The other end of the spring 304 is fixedly connected to the movable plate 301, and the movable plate 301 is slidably connected to the second protective sleeve 202. A sliding groove is provided on the movable plate 301. Through the cooperation between the plug-in rod 303 and the sliding groove, the second protective shell 201 is limited to prevent the second protective shell 201 from loosening during use.

[0026] A plug-in rod 303 is fixedly provided at a position corresponding to the sliding groove on the second protective shell 201 and the movable plate 301, and can prevent the second protective shell 201 from rotating after cooperating with the sliding groove.

[0027] Example 2

[0028] Different from the first embodiment, a sponge pad is fixedly provided inside the second protective shell 201 to protect the male connector 204 and prevent the male connector 204 inside the second protective shell 201 from being damaged by collision.

[0029] A rubber ring is provided at the connection between the second protective shell 201 and the second protective sleeve 202 to seal and prevent water from entering from the connection between the second protective shell 201 and the second protective sleeve 202 .

[0030] The size of the plug-in rod 303 corresponds to the size of the sliding slot, so that the plug-in rod 303 and the sliding slot can be slidably matched.

[0031] Working principle: When in use, the second protective shell 201 is placed corresponding to the first protective shell 101, so that the male connector 204 is aligned with the female connector 105, and the movable plate 301 is moved to separate the plug-in rod 303 from the movable plate 301, and then the second protective shell 201 is rotated to tighten the second protective shell 201 and the first protective shell 101, and at the same time, the male connector 204 and the female connector 105 are tightly plugged. After the second protective shell 201 and the first protective shell 101 are correctly tightened, the movable plate 301 is then loosened, and the elastic force of the spring 304 drives the movable plate 301 to move in the direction close to the second protective shell 201, and the plug-in rod 303 slides with the sliding groove to limit the second protective shell 201, thereby preventing the second protective shell 201 from rotating and causing the connector to loosen.

[0032] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
