Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration compressors, in particular to a fireproof relay cover component with a wire clamp. Background Art

[0002] Existing refrigerator compressors need to be installed with relays and starters when in use. In order to improve safety, they need to be equipped with relay covers. The relay covers cover the relays and starters internally for protection. Both the relays and starters are equipped with wiring to be led out from the relay cover to the outside. However, the relay covers currently used in compressors are mostly made of plastic parts. The fireproof function of plastic relay covers is poor. When the two devices or wiring harnesses catch fire due to abnormal factors, they cannot truly achieve the flame retardant effect, and the plastic parts may also be burned and melted. There are also metal relay cover assemblies, but the metal relay covers are only without wire clips, which cannot fix the position of the wiring harness. The shaking process will cause the wiring to loosen, and the metal relay cover also needs to be equipped with additional cover cards for installation and fixation. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a fireproof relay cover assembly with a wire clamp.

[0004] The specific scheme of the utility model is: a fireproof relay cover assembly with a wire clamp, comprising a relay cover A made of insulating material and a relay cover B made of metal material, the relay cover B outer cover and the outer side of the relay cover A, one side of the relay cover A is provided with a wire outlet, the same side of the relay cover B is provided with a wire outlet, the outer side of the relay cover B is provided with a connecting terminal below the wire outlet, the connecting terminal is provided with a screw hole, the connecting terminal is used to install the wire clamp, and the wire clamp is connected to the connecting terminal by screws.

[0005] Furthermore, the outer wall surface of the relay cover A is provided with a limiting protrusion, and the inner wall surface of the relay cover B is provided with a clamping groove corresponding to the limiting protrusion.

[0006] Furthermore, the shape of the connecting terminal is L-shaped, and a through hole is provided on the relay cover B corresponding to the connecting terminal.

[0007] Furthermore, a buckle matching the protective frame is provided in the relay cover A.

[0008] Furthermore, the wire clamp is made of insulating plastic material.

[0009] Compared with the prior art, the utility model has the following advantages: 1. By arranging a metal relay cover to cover the plastic relay cover and providing connecting terminals, it is convenient to install the wire clamp, thereby preventing the fire of the two devices from spreading outward and fixing the wire harness through the wire clamp to prevent the wire harness from loosening; 2. There is no need to fix the relay cover assembly through the cover clip, and it can be directly installed on the protective frame of the compressor through the buckle inside the relay cover A, which is more convenient to install.

[0017] See also Figure 1-6 The present embodiment provides a fireproof relay cover assembly with a wire clamp 3, including a relay cover A1 made of insulating material and a relay cover B2 made of metal. The relay cover B2 is covered with an outer shell of the relay cover A1. A wire outlet 5 is provided on one side of the relay cover A1, and a wire outlet 5 is provided on the same side of the relay cover B2. A connecting terminal 22 is provided on the outer side of the relay cover B2 below the wire outlet 5. The connecting terminal 22 is provided with a screw 4 hole. The connecting terminal 22 is used to install the wire clamp 3. The wire clamp 3 is connected to the connecting terminal 22 by a screw 4.

[0018] Furthermore, the connection terminal 22 is L-shaped, and a through hole 23 is provided on the relay cover B2 corresponding to the connection terminal 22. The collector cover B in this embodiment is made of stainless steel, and the L-shaped connection terminal 22 is formed by punching.

[0019] Furthermore, a limiting protrusion is provided on the outer wall surface of the relay cover A1, and a slot 21 is provided on the inner wall surface of the relay cover B2 corresponding to the limiting protrusion. The relay cover B2 is assembled by moving horizontally along the opening toward the relay cover A1. When the slot 21 passes over the limiting protrusion, it is installed in place. At this time, the relay cover A1 and the relay cover B2 become a whole.

[0020] Furthermore, a buckle 6 matching the protective frame is provided in the relay cover A1, and installation and fixation are achieved by the cooperation between the buckle 6 and the protective frame of the compressor.

[0021] Furthermore, the wire clamp 3 is made of insulating plastic material, which is the same as the wire clamp 3 of the prior art. When the compressor is installed, the two devices are installed on the protective frame, and then the relay cover assembly of the utility model is installed, and the buckle 6 in the relay cover A1 is connected and fixed to the protective frame, and the wire harnesses of the two devices are led out from the outlet 5 and fixed through the wire clamp 3. If the two devices catch fire due to a fault, even if the internal plastic material relay cover A1 is burned, the external relay cover B2 can still play a fire prevention role, and the wire clamp 3 is located on the outside of the relay cover B2, so the wire clamp 3 will not be burned.
