The application belongs to the technical field of new energy automobile charging, and particularly relates to a direct-current split type charging host, aiming at the problems of inconvenient transportation of the existing split type host, and poor protection effect on the charging terminal, and the following scheme is proposed, which comprises a mounting box, a base is fixedly installed at the bottom of the mounting box, two movable doors are hingedly connected to one side of the mounting box, and a storage bin is fixedly installed at the top of the mounting box; a first charging terminal and a second charging terminal are arranged on the two sides of the mounting box, in the application, the split type charging host can be combined and installed with at most two charging terminals, the split type charging host can be conveniently transported, and the use of the charging state is not affected, and meanwhile, when the charging terminals are installed on the two sides of the charging host, the charging terminals can be continuously shielded, the tarpaulin for shielding can be synchronously extended with the extension of the terminals, and the long-term use of the charging terminals is facilitated.

A contact mechanism of double-contact circuit breaker. Mainly solve the current double-contact circuit breaker using two dynamic contact pieces to set two dynamic contacts to realize breaking, the problem of low synchronization rate. Its characterized in that: the static contact piece includes the main piece, the main piece is provided with the first piece and the second piece integrally manufactured, the static contact point includes the first static contact point arranged on the first piece and the second static contact point arranged on the second piece; the dynamic contact piece includes the piece body, the dynamic contact point includes the first dynamic contact point and the second dynamic contact point arranged on the piece body, the first dynamic contact point and the second dynamic contact point are provided with the gap groove, the first dynamic contact point is arranged opposite to the first static contact point, and the second dynamic contact point is arranged opposite to the second static contact point. The utility model provides a kind of contact mechanism of double-contact circuit breaker, and two dynamic contacts are set on one dynamic contact piece, and the synchronization rate is high, and two static contacts are arranged oppositely, two arcs are generated when breaking, and the energy of single arc is reduced.

The utility model relates to the technical field of arc opening punch forming, in particular to an arc opening punch forming machine for a headrest rod, which comprises a support plate and a lower press plate, two groups of lower templates are arranged at the upper end of the support plate and positioned on two sides of the upper end of the support plate, the lower press plate is arranged above the support plate, and the lower press plate is arranged on the support plate. The lower end of the lower pressing plate is provided with upper mold plates, the upper mold plates are arranged above the lower mold plates in a one-to-one correspondence mode, the lower mold plates and the upper mold plates are pressed to form headrest rod positioning grooves, the upper end of one side of each lower mold plate is provided with an adjusting rail, and the adjusting rail is provided with a headrest rod positioning adjusting block which is assembled with the adjusting rail in a sliding mode. A locking piece is arranged on the side wall of the headrest rod positioning adjusting block; and the punch forming mechanisms are arranged at the upper end of the supporting plate, and the punch forming mechanisms are arranged on one sides of notches of the headrest rod positioning grooves in a one-to-one correspondence mode.
