Ring baffle is provided on face, the open slot is arranged in parallel with water conservancy diversion guard plot；The bottom of the sealing cover is provided with circle
Bottom plate is provided with externally threaded wall surface in the circular bottom plate, is provided centrally with positioning column；External screw thread on the wall surface with
Internal screw thread matches.
The open slot is rectangle, and the length is L1, width 10mm, the length of the internal screw thread is L2, described anti-
The length for protecting bracket is L, wherein L=L1+10mm, L1=L2+10mm.
The water conservancy diversion guard plot is chamfer triangle body structure, and the length on protective stent outer wall is 10mm, tiltedly
Face and protective stent outer wall form 5~10 ° of angle, and surface width is 10 mm.
3 solder joints are evenly arranged on the ring baffle of the protective stent.
Externally threaded length is L2 on the wall surface.
The shape of the positioning column is cylindrical body, cone, any in cuboid.
Compressor connecting wire block can be fixed in technical solution provided by the utility model, it is avoided to loosen,
It falls off, while can effectively solve cannot be effective due to there are gap between existing compressor case and protective stent
The problem of waterproof, promotes compressor electrical safety reliability.

Specific embodiment
1-6 and specific embodiment are described in further detail the utility model with reference to the accompanying drawing:
A kind of protective device of freezer compressor connecting terminal, the protective device is by protective stent 2 and 1 group of sealing cover
At the sealing cover 1 is fixed on protective stent 2 by the external screw thread of wall surface 12 and matching for 2 internal screw thread 24 of protective stent
On one end face, the protective stent 2 is the cylindrical body of both ends open, is stamped with open slot 25 on the post jamb of the cylindrical member at one end
With internal screw thread 24；It is stamped with water conservancy diversion guard plot 26 outside the post jamb of the other end, ring baffle 22, the opening are stamped on end face
Slot 25 is arranged in parallel with water conservancy diversion guard plot 26；
The bottom of the sealing cover 1 is stamped with circular bottom plate 11, is stamped in the circular bottom plate 11 with externally threaded wall
Face 12, center are stamped with positioning column 13；
The open slot 25 is rectangle, and the length is L1, width 10mm, the length of the internal screw thread 24 is L2, institute
The length for stating protective stent 2 is L, wherein L=L1+10mm, L1=L2+10mm.
The water conservancy diversion guard plot 26 is chamfer triangle body structure, and the length on 2 outer wall of protective stent is 10mm,
Inclined-plane and 2 outer wall of protective stent form -7 ° of angle, and surface width is 10 mm.
Externally threaded length is L2 on the wall surface 12.
