Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a relay and an electrical box. Background Art

[0002] In the prior art, at least two installation parts are often set in the same electrical box, and each installation part is respectively installed with a relay for controlling different back-end devices or terminals with different functions. Specifically, a signal control unit with multiple signal output ends is used to connect multiple controlled loads through multiple relays, that is, each signal output part is electrically connected to one of the relays, and the relay is then electrically connected to the corresponding controlled load, so that the signal control unit can finally control the controlled load. Since each relay often has the same function, and sometimes even the same or similar model, each relay often has a similar or even identical appearance, shape and structure. Therefore, when each relay is installed, an installation error often occurs, which causes an error in the control signal sent by the signal control unit to control the controlled load through the relay. For example, a controlled load that should not be turned off is turned off by mistake, or a controlled load that should not be turned on is turned on by mistake, or a controlled load that should be turned off is not turned off correctly, or a controlled load that should be turned on is not turned on correctly. Especially in some high-speed vehicles, such control errors may have fatal consequences. In addition, when only a few relays, such as one relay, need to be installed in the electrical box, it is also very important to install the relays on the corresponding installation parts when the electrical box has multiple installation parts. Once the relay is installed on the wrong installation part, the above-mentioned problem will also occur. Therefore, how to install the relays in the electrical box on the correct installation part is an urgent problem to be solved. Utility Model Content
