[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0025] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0026] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0027] like Figure 1-8 The utility model provides a riveted and solder-free shielding box, comprising a box body 1 and a plate body 2 connected to one side of the box body 1, the outer cover of the box body 1 is provided with a top crimping tool 3, and the outer cover of the plate body 2 is provided with a bottom crimping tool 4, so that when the box body 1 is connected to the plate body 2, the sides of the top crimping tool 3 and the bottom crimping tool 4 are abutted against each other; a plurality of snap rings 5 ​​are arranged at intervals along the edge on one side of the box body 1 close to the plate body 2, a plurality of bayonet holes 6 are arranged at intervals along the edge on one side of the plate body 2 close to the box body 1, and the snap rings 5 ​​match the bayonet holes 6, and the outer periphery of the snap ring 5 is an elliptical structure.

[0028] When the box body and the plate body are connected in this scheme, each clamp ring is aligned with each bayonet position in turn, so that one end of the clamp ring with an elliptical structure is against the bayonet for preliminary positioning, and then the box body is pressed by a press or other pressure equipment, so that several clamp rings are synchronously snapped into the bayonet, so that the other end of the clamp ring with an elliptical structure is snapped into the bayonet, thereby improving the stability of the connection between the box body and the plate body. Since the clamp ring does not need to be fixed with solder, the floating phenomenon between the box body and the plate body is avoided, and the convenience of disassembly between the box body and the plate body is also improved.

[0029] The inner side of the box body is a hollow structure to facilitate the placement of the workpiece to be tested, and the board body is made of PCB board.

[0030] Preferably, a hollow structure 7 is provided inside the clamp ring 5 .

[0031] Specifically, through the setting of the hollow structure, when the clamping ring is pressed relative to the bayonet, the clamping ring is more likely to deform toward the inner hollow structure to ensure that the clamping ring can pass through the bayonet position smoothly, and then restore the elliptical structure of the outer periphery of the clamping ring after passing the bayonet position, so as to ensure the stable clamping fit between the clamping ring and the bayonet.

[0032] Preferably, the width of one side of the snap ring 5 away from the box body 1 is smaller than the maximum width of the snap ring 5 , and the width of the connection between the snap ring 5 and the box body 1 is smaller than the maximum width of the snap ring 5 .

[0033] Specifically, the width of the side of the clamping ring away from the box body is smaller than the maximum width of the clamping ring, so that when the box body and the plate body are initially positioned, they can be positioned by pressing the side of the clamping ring away from the box body against the bayonet position; then after the clamping ring passes through the bayonet, the connection between the clamping ring and the box body is located on the inner side of the bayonet, and at this time the bayonet can be positioned by the maximum width position of the clamping ring.

[0034] Preferably, a side of the bottom crimping tool 4 close to the plate body 2 is provided with an avoidance groove 8 along the circumferential direction, and the avoidance groove 8 is arranged corresponding to the plurality of bayonet holes 6 .

[0035] Specifically, by setting the avoidance groove, after the plate body is installed to the inner side of the bottom crimping tooling, when the box body is crimped onto the plate body, the position of the clamping ring and the bayonet can be avoided through the avoidance groove, thereby avoiding interference between the clamping ring and the bottom crimping tooling when pressing.

[0036] Preferably, a mounting cavity 9 is opened inside the top crimping tool 3 , and the depth of the mounting cavity 9 is less than the thickness of the box body 1 , so that when the box body 1 is loaded in the mounting cavity 9 , the edge position of the box body 1 protrudes from the side of the mounting cavity 9 .

[0037] Specifically, when the box body and the plate body are crimped, the box body and the plate body are respectively loaded into the top crimping tooling and the bottom crimping tooling, so that the press and other pressure equipment will not cause pressing damage to the box body and the plate body. At the same time, since the depth of the installation cavity is less than the thickness of the box body, the edge position of the box body protrudes from the side of the installation cavity, thereby ensuring that the box body can be disassembled from the top crimping tooling.

[0038] Preferably, a limiting boss 10 is provided at the edge corner of the top crimping tool 3 , and when the box body 1 is loaded into the installation cavity 9 , the limiting boss 10 is flush with the edge of the box body 1 .

[0039] Specifically, by setting the limiting boss, when the press machine presses the top crimping tooling, the limiting boss can be used to press against the bottom crimping tooling to limit the pressing stroke between the box body and the plate body, thereby preventing the box body and the plate body from being deformed due to excessive pressure of the press.

[0040] Preferably, when the top crimping tool 3 and the bottom crimping tool 4 are against each other, a gap 11 is provided between the top crimping tool 3 and the bottom crimping tool 4 .

[0041] Specifically, due to the setting of the limiting boss, when the top crimping tooling and the bottom crimping tooling are against each other, gaps will appear on both sides of the limiting boss. Through the gap position, the top crimping tooling and the bottom crimping tooling can be easily disassembled and separated.

[0042] In one embodiment of the present scheme, a plurality of mounting cavities 9 are arranged in an array on the inner side of the top crimping tool 3, and a plurality of avoidance grooves 8 are arranged in an array on the inner side of the bottom crimping tool 4, so that a plurality of box bodies 1 and plate bodies 2 can be loaded between the top crimping tool 3 and the bottom crimping tool 4.

[0043] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
