The multifunctional relay case is combined with a relay main body to form a relay, and the relay main body part comprises a substrate part and an electromagnetic part. Due to the fixing habit in the industry, the housing body 100 is generally connected to the base plate portion of the relay body by a snap spring. Specifically, the two clamp springs are respectively disposed outside the two length direction walls 120 of the housing main body 100; one end of the snap spring is fixed to the base plate portion of the relay main body portion, and the other end of the snap spring presses the top wall 140, thereby fixing the case main body 100 to the relay main body portion. Certainly, the root of the housing main body 100 and the relay main body part form a sleeving, clamping and combining mode, and the housing main body 100 is limited to be separated from the relay main body part in a direction parallel to the relay main body part; however, this makes it possible to operate only from the direction perpendicular to the relay body portion if the housing body 100 is to be attached or detached, and the clamp spring is set to have a large fastening force for fixing the housing body 100, which limits smooth attachment and detachment of the housing body 100.

In the present invention, a chamfer structure 150 is provided between at least one of the longitudinal walls 120 and the top wall 140, i.e. the chamfer structure 150 lacks a part of corner angle, so that the process of mounting or dismounting the housing main body 100 is smoother. Specifically, taking the case that the chamfer structure 150 is arranged on the outer side between one of the two length direction walls 120 and the top wall 140, in the process of installing the housing main body 100, the clamp spring without the chamfer structure 150 side is held and broken off, the housing main body 100 is pressed into the relay main body part, and at this time, the clamp spring with the chamfer structure 150 side can be conveniently inserted into the position through the chamfer structure 150 to press the top wall 140; the clamp spring on the side without the chamfered structure 150 is released and can also press the top wall 140. In the process of disassembling the housing body 100, the clamp spring without the chamfer structure 150 side is held and broken off, the housing body 100 is pulled out from the relay body part, and the clamp spring with the chamfer structure 150 side can be conveniently separated from the top wall 140 through the chamfer structure 150, so that the housing body 100 can be smoothly taken down. It should be noted that, in the present embodiment, a chamfer structure 150 is provided between one of the two longitudinal walls 120 and the top wall 140 on the outer side, and one of the two snap springs can completely ensure the fixing effect on the top wall 140.
