[0018] In the following, the present application will be further described in combination with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0019] As Figs. 1-3As shown, an easy-to-assemble center conductor includes a base 1, a rod body 2 fixedly arranged on the top of the base 1, and a terminal 3 movably arranged on the upper part of the rod body 2, characterized in that the upper part of the rod body 2 is provided with a threaded part 21, a nut 4 is rotatably arranged on the threaded part 21, and the terminal 3 is sleeved on the outer side of the rod body 2 and in contact with the top of the nut 4; a first limiting groove 22 is arranged on the outer wall of the rod body 2, a plurality of second limiting grooves 31 are arranged on the inner wall of the terminal 3, and a third limiting groove 40 is arranged on the inner wall of the nut 4; when the first limiting groove 22, the third limiting groove 40, and any one of the second limiting grooves 31 are in a state of mutual communication, a limiting rod 5 is inserted into the first limiting groove 22, the third limiting groove 40, and the corresponding second limiting groove 31.

[0020] During assembly, the nut 4 is first rotated downward, then the terminal 3 is sleeved on the rod body 2, the height of the nut 4, i.e. the angle of the terminal 3, is adjusted, so that the terminal 3 is in a state of being about to be connected with a to-be-connected part, the positions of the nut 4 and the terminal 3 are finely adjusted, so that the first limiting groove 22 on the rod body 2 and the third limiting groove 40 on the nut 4 are aligned with the closest second limiting groove 31 on the terminal 3, at this time, the limiting rod 5 is inserted into the first limiting groove 22, so that one side of the limiting rod 5 is located in the first limiting groove 22, and the other side of the limiting rod 5 is located in the second limiting groove 31 and the third limiting groove 40, thereby connecting the rod body 2, the nut 4, and the terminal 3 into an integral whole, ensuring the accuracy during installation and the stability during use, and further ensuring that the center conductor can be in a reliable working state.

[0021] The second limiting groove 31 and the third limiting groove 40 are in communication with each other in the vertical direction, and the first limiting groove 22 and the second limiting groove 31 and the first limiting groove 22 and the third limiting groove 40 are in communication with each other in the horizontal direction, so that the limiting rod 5 can be located in the first limiting groove 22, the third limiting groove 40, and the corresponding second limiting groove 31 at the same time, ensuring the reliable limiting effect of the limiting rod 5 on the nut 4 and the terminal 3.

[0022] The top of the first limiting groove 22 is in communication with the top of the rod body 2, and the bottom of the first limiting groove 22 passes through the threaded part 21 and is located below the threaded part 21, that is, the limiting rod 5 can be conveniently inserted into the first limiting groove 22 from the top of the first limiting groove 22, improving the insertion efficiency and facilitating blind operation by installers.

[0023] The terminal 3 is in the form of a clamp and is locked by a bolt 32. A plurality of second limiting grooves 31 are arranged at intervals along the inner wall of the terminal 3 and penetrate the terminal 3. After the bolt 32 locks the terminal 3, the terminal 3 can tightly clamp the outer wall of the rod body 2, thereby improving the connection tightness of the terminal 3 and the rod body 2.

[0024] The top of the terminal 3 is provided with a plurality of clamping grooves 33, and the clamping grooves 33 are respectively and one-to-one communicated with the top of the second limiting grooves 31. The top of the limiting rod 5 is provided with a clamping block 51 which is adapted to be arranged in the clamping groove 33. When the clamping block 51 is clamped into the clamping groove 33, the limiting rod 5 cannot be moved, thereby achieving the limiting effect of the limiting rod 5 and ensuring that the limiting rod 5 can be simultaneously located in the first limiting groove 22, the second limiting groove 31 and the third limiting groove 40, thereby playing a limiting effect on the rod body 2, the terminal 3 and the nut 4 and ensuring that the terminal 3 will not be loose during installation and use.

[0025] The top of the limiting rod 5 is provided with a handle 52 which is used to pull the limiting rod 5 and the clamping block 51. The handle 52 is arranged to facilitate the installation personnel to take and place the limiting rod 5, thereby further improving the installation efficiency.
