It should be noted that the descriptions of these embodiments are used to help understand the present application and do not constitute limitations on the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0020] Referring to Figure 1 and Figure 2 , a bidirectional plug-in terminal wire includes a male terminal group 1 arranged on a circuit board, and a terminal connecting wire 2 for connecting the male terminal group 1 of two circuit boards, the terminal connecting wire 2 includes a wire harness 21, female terminals 22 arranged at both ends of the wire harness 21, the female terminals 22 are inserted into the male terminal group 1, the male terminal group 1 includes a male terminal body 11, a plurality of buckle plates 12 are arranged symmetrically along the central axis of the male terminal body 11, one end of the buckle plate 12 is rotatably connected with the male terminal body 11, the other end of the buckle plate 12 is provided with an elastic pin 13, and the female terminal 22 is provided with a pin hole 221 for embedding the elastic pin 13.

[0021] The present application can effectively prevent the female terminal 22 from being separated from the male terminal body 11 due to external forces such as irregular vibration, avoid signal transmission interruption, and further cause equipment failure and other problems by rotating the buckle plate 12 and embedding the elastic pin 13 in the pin hole 221.

[0022] Specifically, the buckle plate 12 includes a first connecting part 121 and a second connecting part 122, the first connecting part 121 and the second connecting part 122 are connected in an L shape, the first connecting part 121 is rotatably connected with the male terminal body 11 through a pivot 14, the second connecting part 122 is provided with an installation slot 123, and a baffle 16 for plugging the installation slot 123 is connected, the elastic pin 13 is in a T shape, one end of the elastic pin 13 extends out of the baffle 16, and the installation slot 123 is provided with a spring 15 abutting against the rear end of the elastic pin 13.

[0023] Specifically, the baffle 16 is connected to the second connecting part 122 by screws, and the above structure facilitates the assembly of the telescopic elastic pin 13 and the buckling plate 12, and the spring 15 keeps the one end of the telescopic elastic pin 13 in the state of extending out of the baffle 16. The other end of the telescopic elastic pin 13 is connected with the pull rope 18, and the other end of the pull rope 18 is knotted through the second connecting part 122, so that the other end of the pull rope 18 is kept extending out of the second connecting part 122.

[0024] The male terminal body 11 is provided with a plug 111, and the outer periphery of the plug 111 is provided with a plurality of sealing rings 17. The female terminal 22 is provided with a plug hole 222 for inserting the plug 111. The bottom of the plug hole 222 is provided with a plurality of conductive tabs 23, and the plug 111 is provided with a conductive hole 112 for embedding the conductive tabs 23. The specific connection structure of the conductive hole 112 arranged on the male terminal body 11 and the conductive tabs 23 arranged on the female terminal 22 belongs to the prior art.

[0025] The diameters of the sealing rings 17 along the direction from the outer end to the inner end of the plug 111 are sequentially increased. Therefore, when the plug 111 is inserted into the plug hole 222, the deformation amount of the sealing ring 17 at the inner end is greater than that of the sealing ring 17 at the outer end, so that the sealing degree is sequentially increased, and the sealing effect is improved.

[0028] When the male terminal body 11 needs to be detached from the female terminal 22, the pull rope 18 is pulled to overcome the deformation of the spring 15, then the telescopic elastic pin 13 is disengaged from the pin hole 221, and then the first connecting part 121 is rotated around the rotating shaft 14 to realize the detachment of the male terminal body 11 and the female terminal 22, which is simple and convenient to operate.
