The width of second segment 222 is less than load platform 300 close to the width of the end of bottom wall 100.Second segment 222 is deployed into Where bottom wall when plane, side wall 200 is not interfered with load platform 300.
Although being limited to existing inventors have found that cost is relatively low for the existing shell processed by the way of plate stamping Processing method, 200 notch of housing sidewall at load platform 300 is bigger than normal, and it is less to what is used to influence electrical property.Further , why the processing of existing plate stamping can the notch expansion shape bigger than normal for being mainly constrained to plate at load platform 300 Shape interferes, and is mainly reflected in: the two side walls 200 adjacent with load platform 300 are launched into plate Shi Huiyu load platform 300 interference.
Accordingly, inventor devises a kind of microwave isolator cavity 100, and the side wall 200 of cavity, bottom wall 100 and load are flat Platform 300 is formed by same plate stamping, such processing method compared to powder metallurgy, machining can reduce cost, It improves efficiency, there is outstanding economic benefit.Meanwhile loading notch 220 includes first segment 221 interconnected and second segment 222;First segment 221 is located remotely from one end of bottom wall 100 close to one end of bottom wall 100, second segment 222;The width of first segment 221 More than or equal to load platform 300 close to the width of the end of bottom wall 100;The width of second segment 222 is less than load platform 300 and leans on The width of the end of nearly bottom wall 100.First segment 221 can ensure that the adjacent two side walls 200 of load platform 300 are launched into plate Shi Buhui and load platform 300 are interfered, and have ensured going on smoothly for punching press movement;The width of second segment 222 is less than load platform 300 close to the end of bottom wall 100 width, then reduce load notch 220 width, ensured microwave isolator cavity 100 With outstanding electrical property.
From this figure it can be seen that above-mentioned bottom wall 100 is cylindrical body in the present embodiment of the utility model;Side wall 200 Along cylindrical body periphery annular spread.Therefore, side wall 200 is also arc-shaped to match with bottom wall 100.
And in the present embodiment, the edge of above-mentioned load notch 220 symmetrically is located at the two sides of load platform 300. Meanwhile above-mentioned second segment 222 is straight rectangular aperture.
Further, above-mentioned from bottom wall 100 to close to 222 edge of second segment in the present embodiment of the utility model Direction, first segment 221 seamlessly transit the tapering width so that first segment 221.The mode of smooth transition has ensured first segment 221 stability connecting with second segment 222 have ensured the stability of load opening structure, and what is seamlessly transitted in this way opens Mouth is more suitable for fabricating.
Optionally, in the present embodiment of the utility model, above-mentioned 221 straight transitions of first segment, so that 221 shape of first segment At horn-like.
Specifically, load 220 bottom of notch (first segment 221) size is kept to be greater than or equal to 300 width of load platform Under the premise of, notch size is gradually reduced, when 200 part of side wall and 300 part of load platform for narrowing down to expansion plate are not interfered Stop reducing, straight small size notch (second segment 222) is shaped to upwards, to reduce the face of notch herein on the whole Product, to improve the electrical property of isolator.
In the present embodiment of the utility model, above-mentioned load platform 300 is parallel to each other with bottom wall 100;Or load platform 300 are generally aligned in the same plane with bottom wall 100.The mode being arranged in this way be conducive to ensure load platform 300 connect with bottom wall 100 it is steady It is qualitative, ensure the load stress-bearing capability of load platform 300.
The situation that load platform 300 and bottom wall 100 are generally aligned in the same plane is all illustrated in Fig. 2 and Fig. 3.
Optionally, in the present embodiment, above-mentioned load platform 300 includes convex to the rectangle extended far from 100 direction of bottom wall It rises, and the interconnecting piece that rectangular preiection is connect with bottom wall 100.
Further, in the present embodiment of the utility model, have between above-mentioned first notch 210 and bottom wall 100 One pre-determined distance.It is arranged such and has ensured that multiple connection pins of center conductor can easily stretch out from the first notch 210.
It should be noted that first segment 221 is not limited to straight transitions and forms loudspeaker in the case of first segment 221 seamlessly transits Shape, in the other embodiments of the utility model, first segment 221 can also be arc transition etc., here only one show Example.
Embodiment 2
Referring to figure 4., Fig. 4 be the utility model the present embodiment provides a kind of structures of microwave isolator cavity 100 to show It is intended to, is substantially the same with the microwave isolator cavity 100 of embodiment 1, the difference is that:
In the present embodiment of the utility model, above-mentioned first segment 221 is rectangular aperture, and the width of rectangular aperture bottom is big In or equal to load platform 300 close to the end of bottom wall 100 width.
Under the premise of ensureing that the bottom size of first segment 221 is greater than or equal to 300 width of load platform, so that expansion plate When 222 side wall of second segment, 200 fractional load of material and 300 part of load platform are not interfered.And second segment 222 is still small The rectangular aperture of size, to reduce the area for loading notch 220 herein on the whole, to improve the electrical property of isolator.
The technical solution of the utility model embodiment is at least had the following advantages and beneficial effects:
The side wall 200 of microwave isolator cavity 100, bottom wall 100 and load platform 300 are formed by same plate stamping, Such processing method can reduce cost compared to powder metallurgy, machining, improve efficiency, with outstanding economic effect Benefit.Meanwhile loading notch 220 includes first segment 221 interconnected and second segment 222;First segment 221 is close to bottom wall 100 One end, second segment 222 are located remotely from one end of bottom wall 100;It is close that the width of first segment 221 is greater than or equal to load platform 300 The width of the end of bottom wall 100;The width of second segment 222 is less than load platform 300 close to the width of the end of bottom wall 100.The Can ensure for one section 221 will not interfere when the adjacent two side walls 200 of load platform 300 are launched into plate with load platform 300, Going on smoothly for punching press movement is ensured;The width of second segment 222 is less than load platform 300 close to the width of the end of bottom wall 100 Degree then reduces the width of load notch 220, has ensured that microwave isolator cavity 100 has outstanding electrical property.
