Referring to fig. 6 and 7, it can be appreciated that in the above embodiment, in order to avoid the contact of the fastening member with the terminal 310 when the fastening member is inserted into the connection hole 123, a protection plate 230 may be further disposed inside the terminal cover 200, and the protection plate 230 separates the fastening member from the terminal 310, so that the fastening member can be prevented from contacting the terminal 310, which is beneficial to further improving the safety of the refrigeration apparatus.
Referring to fig. 2 and 7, it can be understood that in the above embodiment, the connecting hole 123 may be disposed at one end of the first boss 121 near the bottom plate 110, when the terminal cover 200 is covered on the terminal box 100, the first boss 121 abuts against the inner wall of the terminal box 100, and at this time, the fastening member may be disposed through the connecting hole 123 and the mating hole 220, so that the terminal cover 200 is further fixed on the terminal box 100, which is beneficial to preventing the terminal box 100 from being separated from the terminal box 100 under the action of external force such as vibration, and improving the stability of the terminal cover 200 mounted on the terminal box 100.
Referring to fig. 2, in the above embodiment, since the connection hole 123 occupies a part of the area of the first boss 121, the first boss 121 is abutted against the inner wall surface of the terminal cover 200 by its surface to fix the terminal cover 200 to the terminal box 100.
In some embodiments of the present invention, in order to increase the contact area between the first boss 121 and the inner wall of the terminal cover 200, the other end of the first boss 121 opposite to the connection hole 123 may be further provided with an extension portion 124, and the extension portion 124 extends in a direction away from the bottom plate 110, so that the contact area between the first boss 121 and the inner wall of the terminal cover 200 may be increased, which is beneficial to improving the stability of mounting the terminal cover 200 to the terminal box 100.
A refrigeration unit (not shown) according to an embodiment of the fourth aspect of the present invention includes a compressor according to an embodiment of the third aspect of the present invention. Specifically, the refrigerating device may be a refrigerating device such as an air conditioner or a refrigerator.
The refrigeration apparatus according to the fourth aspect of the present invention includes the compressor according to the third aspect of the present invention, in which the terminal cover 200 is mounted on the terminal box 100 by providing the housing assembly, and the terminal box 100 is provided with the first boss 121 and the second boss 131, so that when the terminal cover 200 is mounted on the terminal box 100, only the terminal cover 200 needs to be covered on the terminal box 100, so that the first boss 121 and the second boss 131 abut against the inner wall of the terminal cover 200, and the terminal cover 200 is mounted on the terminal box 100, which is convenient and quick to mount.
When the terminal cover 200 is detached, only the terminal cover 200 is lifted slightly by force along the direction deviating from the bottom plate 110, so that the inner wall of the terminal cover 200 is separated from the first boss 121 and the second boss 131, the terminal cover 200 is detached from the terminal box 100, the operation is very convenient, the disassembly and assembly efficiency of the refrigerating device is improved, the terminal box 100 is simple in structure, the processing is more convenient, and the processing cost of the refrigerating device is reduced.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
