At this time, the outer surfaces of the two stoppers 205 are in the situation where the connection terminal body 5 penetrates into the terminal box body 1 and contacts and squeezes the two contact plates 306. Under the condition that there is no external shielding, the two groups of multiple first springs 202 will push the two stoppers 205 to move outwards respectively under the action of elastic reset, so that the two stoppers 205 will block the front side of the terminal body 5 under the reset condition. At the same time, the external force on the terminal body 5 is released, and the rebound force of the two groups of multiple second springs 303 will push the push block 305, so that the front surfaces of the two contact plates 306 will tightly contact the rear surface of the terminal body 5, so that it is fixed in the two symmetrical installation grooves 4, which plays a role in rapid installation, and pulls the connecting blocks 208 corresponding to the two positions so that they pass The fixing rod 206 drives the corresponding block 205, so that the two blocks 205 can shrink and avoid into the two first installation boxes 201 under the action of pulling force, so that personnel can quickly take out the terminal body 5. By respectively opening limit grooves 207 at the top and bottom of the block 205, the inner surface of the first installation box 201 is symmetrically fixed with the limit block 203, so that when the block 205 slides outward, the limit block 203 will slide in the limit groove 207 synchronously, which plays a role of limiting, preventing the block 205 from sliding out of the installation groove 4 as a whole without obstruction, affecting the normal installation of the terminal body 5, and having high practicality.
