Detailed Description
The following description of a preferred embodiment of the present invention will be made in conjunction with the accompanying drawings. However, the scope of the present invention is not limited to the following embodiments, and all simple equivalent changes and modifications made by the claims and the contents of the specification are still included in the scope of the present invention.
Referring to fig. 1-5, for a main contact external connection mechanism of high voltage direct current relay, including a pair of main contact 2 of locating on high voltage direct current relay 1, be equipped with mounting hole 21 on the outer terminal surface of this main contact 2, there is terminal rod 3 through the threaded fixation in this mounting hole 21, is equipped with installation locating hole 31 on the outer terminal surface of this terminal rod. This installation locating hole 31 can be hexagon socket head cap locating hole, or a word locating hole, or cross locating hole etc. the utility model discloses do not specifically prescribe a limit to.
The periphery of the junction pole 3 is also provided with threads, and the upper end of the junction pole is externally provided with an anti-slip nut 4 through thread meshing. The slip-preventing nut 4 includes a nut body 41 and a slip-preventing piece 42 provided on one end face of the nut body. The anti-skid member 42 is cylindrical, a threaded hole is formed in the center of the anti-skid member and is consistent with the nut body, anti-skid teeth 43 in the same direction are arranged at intervals on the edge of one side surface far away from the nut body, and an included angle is formed between the anti-skid teeth 43 and the radius of the anti-skid member 41.
This main contact external connection mechanism is when installation copper bar 5 or binding post (using the copper bar as an example), place copper bar 5 and anti-skidding nut 4 on main contact 2's up end in proper order earlier, the mounting hole that sets up on the copper bar 5, the center of anti-skidding nut 4 corresponds with mounting hole 21 on the main contact 2, then correspond the lower extreme of binding post 3 and penetrate the mounting hole, because binding post 3 has set up installation locating hole 31, consequently can install the binding post through the instrument, and not only easy operation, and the installation is firm. During the installation, owing to the antiskid tooth 43 that sets up on the antiskid nut 4, further inject copper bar 5, the copper bar slides when preventing the installation, further ensures the reliability of connecting.
Therefore, the main contact external wiring mechanism can reliably install and connect the copper bar or the wiring terminal by means of the tool through the installation positioning hole arranged on the wiring rod, and further ensures the installation reliability by means of the anti-slip nut, and has the advantages of simple structure, convenience in installation, stable and reliable connection, difficulty in occurrence of defects such as thread sliding and the like.
