Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an anti - detachment sealed terminal and a compressor. Background Art

[0002] At present, most refrigerator compressors are connected to a starter and a protector by an external power supply, and then the starter and the protector are connected to the compressor sealed terminal by insertion. The compressor sealed terminal usually consists of a glass body surrounding a cylindrical guide post, so as to insulate the inside and outside of the compressor. Since the three guide posts of the existing sealed terminal are cylindrical, when the starter and the protector are connected to the sealed terminal, the problem that the starter and the protector become loose often occurs due to insufficient insertion and extraction force, resulting in the abnormal operation of the refrigerator compressor. Summary of the Invention

[0003] The purpose of the utility model is to solve the problems existing in the above - mentioned prior art, and provide an anti - detachment sealed terminal and a compressor.

[0004] The specific scheme of the utility model is as follows: an anti - detachment sealed terminal includes a substrate, three mounting holes are provided on the substrate, a guide post is installed in each mounting hole, a glass body is provided between the guide post and the mounting hole, and a section of conical body is provided at the outer end of the guide post, and the diameter of the end of the conical body facing the substrate is larger than that of the other end; the conical body is used to increase the insertion and extraction force between the starter and / or the protector and the guide post.

[0005] Further, the maximum diameter of the conical body is larger than the jack of the starter and / or the protector, so as to limit the insertion depth of the starter and / or the protector.

[0006] Further, the side wall of the conical body is provided with an inward - concave arc surface.

[0007] Further, the head of the conical body is provided with a transition fillet.

[0008] The utility model also provides a compressor, which includes a housing, and the above - mentioned anti - detachment sealed terminal is installed on one side of the housing.

[0009] The utility model has the following advantages compared with the prior art: 1. By arranging a conical body at the outer end of the guide post, it can better fit the connection buckle of the starter and the protector, thereby increasing the insertion and extraction force, avoiding the problem that the starter and the protector become loose and causing the abnormal operation of the refrigerator compressor, and improving the reliability of the compressor.

[0010] 2. The conical body can also limit the insertion depth of the starter and the protector, avoid scratching the glass body and damaging the insulation property, and improve the reliability of the compressor. Brief Description of the Drawings

[0015] See Figures 1-3 , this embodiment provides an anti-detachment sealed terminal, including a substrate 1, three mounting holes are provided on the substrate 1, a guide post 3 is installed in each mounting hole, a vitreous body 2 is provided between the guide post 3 and the mounting hole, and a section of cone 4 is provided at the outer end of the guide post 3, and the diameter of the end of the cone 4 facing the substrate 1 is greater than the other end; the cone 4 is used to increase the insertion and extraction force between the starter and / or protector and the guide post 3.

[0016] Further, the maximum diameter of the cone 4 is greater than the jack of the starter and / or protector, thereby limiting the insertion depth of the starter and / or protector.

[0017] Further, the side wall of the cone 4 is provided with an inwardly concave arc surface.

[0018] Further, the head of the cone 4 is provided with a transition fillet, so that the starter and / or protector can be smoothly inserted into the guide post 3. This embodiment also provides a compressor, including a housing, and the above anti-detachment sealed terminal is installed on one side of the housing. The outer ring of the substrate 1 of the sealed terminal is welded to the corresponding mounting hole of the housing. By increasing the cone 4, the diameter of the guide post 3 is increased, so that the cooperation between the guide post 3 and the jack of the starter or protector is tighter, thereby realizing the improvement of the insertion and extraction force and avoiding the detachment of the starter and / or protector.
