Footpath is usually more than 65mm.
Alternatively, micro-compressor can be vertical compressor.Certainly, those skilled in the art are appreciated that micro-
Type compressor can also be horizontal compressor (not shown).In the application explained below, with micro-compressor
For illustrating as a example by vertical compressor.
As depicted in figs. 1 and 2, the upper shell 100 for micro-compressor of embodiment according to a first aspect of the present invention,
Including: roof 1 and the first side wall 2, the first side wall 2 is arranged around the periphery of roof 1.For example, referring to 1 and Fig. 2,
Upper shell 100 can be formed as the bowl structure of open at its lower end, but is not limited to this.
Specifically, roof 1 is formed with the binding post installing hole portion 11 that through at least two is circular, say, that
The quantity in binding post installing hole portion 11 can be two or more, and for example, referring to Fig. 3, binding post is pacified
Dress hole portion 11 can be three, and three binding post installing hole portions 11 can be distributed on roof 1 in product shape.
With reference to Fig. 1, in binding post installing hole portion 11, insulating part 6 such as pottery, glass etc., terminals can be provided with
Son 7 is arranged in binding post installing hole portion 11 by insulating part 6.Such as, binding post 7 can be sintered in insulation
In part 6, insulating part 6 can be sintered in binding post installing hole portion 11, thus, it is possible to improve micro-compressor
The inner space utilization rate of upper shell 100, and simple in construction, easy to process.
Specifically, the sidewall in each binding post installing hole portion 11 is provided with flange 111, roof 1 and flange 111 it
Between chamfering 12 transition, by the first arc surface 13 between the side surface towards overbending direction and the roof 1 of flange 111
Connect.It is to say, a side surface of the central axis away from binding post installing hole portion 11 of flange 111 is (outside i.e.
Surface) it is connected by the first arc surface 13 with between roof 1.Wherein, chamfering 12 can be by binding post installing hole
The sidewall in portion 11 is directed away from the direction of the central axis in binding post installing hole portion 11 and tilts to extend formation, flange 111
Can extend up or down from the sidewalls vertical in binding post installing hole portion 11.

The aperture in binding post installing hole portion 11 is d, and the height of flange 111 is h, wherein the height h of flange 111, first
The radius r of arc surface 13, the maximum gauge t of flange 111, the thickness T of roof 1 and binding post installing hole portion 11
Aperture d meet: t≤h≤r+d*T/t.Thus, by the relevant chi in appropriate design binding post installing hole portion 11
Very little, insulating part 6 can be sintered in binding post installing hole portion 11 easily, and drastically increase insulating part 6
Structural strength, thus improve the reliability of upper shell 100.Additionally, also significantly reduce difficulty of processing, fall
Low processing cost.
The upper shell 100 for micro-compressor according to embodiments of the present invention, by appropriate design binding post installing hole
The relative dimensions in portion 11 so that the radius r of the first arc surface 13, the maximum gauge t of flange 111, the thickness of roof 1
Degree T, the aperture d in binding post installing hole portion 11, the height h of flange 111 meet: t≤h≤r+d*T/t, thus,
Easily insulating part 6 can be sintered in binding post installing hole portion 11, and drastically increase the knot of insulating part 6
Structure intensity, thus improve the reliability of upper shell 100.Additionally, also significantly reduce difficulty of processing, reduce
Processing cost.
According to some embodiments of the present invention, the maximum gauge t of flange 111, the thickness T of roof 1 meet: 0.35T
≤t≤T.Its concrete numerical value can adjusted design according to the actual requirements.Such as, t and T can meet further: t=0.5T
Deng.Thus, it is effectively improved the structural strength of flange 111, and create a further reduction difficulty of processing.
