Problems solved by technology
However, in today's relays, in order to prevent the connected high-voltage components from being short-circuited due to air breakdown, the distance between the terminals is usually elongated.
However, this method will undoubtedly cause the relay to be too large and bloated, which is not conducive to use

The invention relates to the technical field of electric control, and concretely relates to an insulation isolation type electromagnetic relay. The relay comprises a shell, an electromagnetic unit, a control unit and a plurality of contact units, the electromagnetic unit, the control unit and the contact units are arranged on the shell, each contact unit comprises a switching-on assembly and two static contacts, the static contacts are connected with terminals, the terminals protrude out of the shell, the electromagnetic unit is used for driving the control unit to act, and the control unit is used for driving the switching-on assembly to act so that the switching-on assembly can abut against or be separated from the two static contacts. An isolation block is arranged between every two adjacent terminals, and the isolation blocks are arranged on the outer wall of the shell. The relay is simple in structure, the isolation blocks are additionally arranged between the adjacent terminals and used for isolating the adjacent terminals, so that air breakdown type short circuit caused by too close high-voltage parts connected with the terminals is avoided, and the use safety of the relay can be guaranteed while the compact structure of the relay is kept.
Description
technical field [0001] The invention relates to the technical field of electric control, in particular to an insulating and isolating electromagnetic relay. Background technique [0002] At present, the casing of the relay is usually made of insulating material, and the terminals connected with the moving contacts protrude out of the casing for connection with high-voltage components. However, in today's relays, in order to prevent the connected high-voltage components from being short-circuited due to air breakdown, the distance between the terminals is usually lengthened. However, this method will undoubtedly cause the relay to be too large and bloated, which is not conducive to use. Contents of the invention [0003] Aiming at the problems in the prior art, the invention provides an insulating and isolating electromagnetic relay, which can isolate adjacent terminals, ensures compact structure and avoids short circuit between adjacent terminals. [0004] In order to so...
