Specific meanings of the above terms in the embodiments of the present application can be understood in specific cases by those of ordinary skill in the art.
The embodiment of the application discloses binding post lid connection structure.
Referring to fig. 1 to 3, an embodiment of a connection structure of a terminal box cover includes: connecting the screw 1 and the terminal box cover 2; the connection screw 1 includes: a tip 11 and a threaded rod 12; the threaded rod 12 comprises a non-threaded section 121 and a threaded section 122, and the non-threaded section 121 is fixedly connected with the end head 11; the unthreaded section 121 is of equal length to the threaded section 122; the terminal box cover 2 is provided with a convex connecting block 22, a first connecting hole 21 and a second connecting hole 23; a cavity 24 is arranged in the connecting block 22; the first connecting hole 21 is arranged at the top of the connecting block 22 and communicated with the cavity 24; the first connecting hole 21 is provided with an internal thread for the connecting screw 1 to penetrate into the cavity 24; the second connecting hole 23 is arranged at the bottom of the connecting block 22, is communicated with the cavity 24 and is used for connecting the connecting screw 1 with the connecting terminal after penetrating out of the cavity 24; the length of the cavity 24 in the vertical direction is as long as the unthreaded section 121 and the threaded section 122.
Specifically, the length of the unthreaded section 121 and the length of the threaded section 122 are the same as the length of the cavity 24, so that the terminal box cover 2 can be taken down by unscrewing the connecting screw 1 until the threaded section 122 is in contact with the first connecting hole 21 during maintenance; and the unthreaded section 121 is in unthreaded contact with the first connecting hole 21, so that the torque required for screwing out the connecting screw 1 can be reduced, and meanwhile, a warning effect is provided for judging whether the threaded section 122 is in contact with the first connecting hole 21.
Correspondingly, a threaded hole for mounting the connecting screw 1 is formed in the position, corresponding to the second connecting hole 23, of the connecting terminal; the depth of the threaded bore may be as long as the length of the threaded section 122 or may be greater than the length of the threaded section 122.
Because the lengths of the unthreaded section 121, the threaded section 122 and the cavity 24 are the same, when the terminal box cover 2 is installed, the connecting screw 1 is screwed until the end 11 is contacted with the connecting block 22, and at the moment, the terminal box cover 2 is installed in place, the connecting screw 1 does not need to be screwed, so that the possibility of sliding teeth or damage of the connecting screw 1 caused by over-screwing of the connecting screw 1 and a threaded hole can be reduced; when the maintenance is needed, the connecting screw 1 is screwed to the threaded section 122 to be in threaded connection with the first connecting hole 21, and the connecting screw 1 does not need to be separated from the terminal box cover 2, so that the risk that the connecting screw 1 falls off is reduced.
Further, the head 11 is provided with a seal hole 111 for passing a wire through the locking coupling screw 1.
Specifically, a fixed through hole 252 may be provided at a position such as the terminal cover 2, and the wire may pass through the through hole and the seal hole 111 in sequence, so that the connection screw 1 cannot be completely removed before the wire is removed, thereby reducing the occurrence of electricity stealing behavior.
In an embodiment, the through hole 252 is disposed on the sealing ring 25 disposed on the terminal box cover, and is used for matching with the sealing hole 111 to lock the connection screw 1.
Further, the connection screw 1 is made of stainless steel, ensuring rigidity.
Further, the terminal box cover 2 is made of an insulating material, so that the risk of electric shock is reduced.
Although the present invention has been described in detail with reference to examples, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention.
