[0028] Example 1

[0029] Combination Figure 1-Figure 6 To illustrate the present embodiment, a new type of measurement and control unit profile chassis disclosed in the present embodiment includes an upper profile cover plate 1, a lower profile cover plate 2, a left side plate 3, a right side plate 4 and a front panel 5. The left side plate 3 and the right side plate 4 are respectively fixed on both sides of the upper profile cover plate 1 and the lower profile cover plate 2 to form a rectangular frame. The fixing method can be detachable fixing with screws, for example, countersunk screws are used, which do not protrude from the plane and can also ensure that the surface is smooth, simple and beautiful.

[0030] like Figure 1 and Figure 2As shown, the upper profile cover plate 1 and the lower profile cover plate 2 have the same structure, which is used to realize the interchange of the two covers, that is, the same mold can be used for production, and there is no need to distinguish the mold of the upper profile cover plate 1 and the mold of the lower profile cover plate 2 separately. The upper profile cover plate 1 and the lower profile cover plate 2 are both provided with a plurality of mutually parallel guide grooves 6, and the guide grooves 6 are divided into a plurality of groups, and each adjacent group of guide grooves 6 is left empty for reserving positions for the electronic components on the printed board. That is to say, when the printed board is inserted into the guide groove 6, the electronic components fixed on the printed board are located in the empty position, on the one hand, it is avoided that the electronic components interfere with each other after the two relatively arranged printed boards are inserted into the guide groove 6, resulting in damage to the electronic components or circuits, and on the other hand, the number of grooves of the mold is reduced, thereby improving the yield rate of the upper and lower profile cover plates, and the width of each guide groove 6 is adapted to the width of the printed board. The printed board adopts the rear plug-in type, and the plug-in board is inserted from the rear through the guide groove 6, which is convenient for plugging in the European-style terminal on the end face of the printed board. Since a plurality of guide grooves 6 are provided on both the upper profile cover plate 1 and the lower profile cover plate 2, the front panel 5 may have nowhere to be fixed. Therefore, threads are provided in the guide grooves 6 where the front panel 5 needs to be fixed, thereby forming threaded fixing holes with the guide grooves 6 for fixing the front panel 5. This eliminates the need for separately opening fixing holes and can utilize the already formed guide grooves 6, thus killing two birds with one stone.

[0031] like Figure 3 As shown, the guide groove 6 is a groove opened on the upper profile cover plate 1. Alternatively, the guide groove 6 can also be a groove formed by adding a protrusion on the upper profile cover plate 1. Both sides of the guide groove 6 on the upper profile cover plate 1 and the lower profile cover plate 2 are provided with a protruding fixing portion 7, which is higher than the two sides of the groove. The left side plate 3 and the right side plate 4 are symmetrical structures. The left side plate 3 and the right side plate 4 are fixedly connected to the upper profile cover plate 1 and the lower profile cover plate 2 through the protruding fixing portion 7 to form a rectangular frame. The guide groove 6 and the protruding fixing portion 7 are both integrally formed structures.

[0032] The novel measurement and control unit profile chassis further includes a left hanging ear 8 and a right hanging ear 9, wherein the left hanging ear 8 is fixed on the left side plate 3, and the right hanging ear 9 is fixed on the right side plate 4. The left hanging ear 8 and the right hanging ear 9 are symmetrical structures, and both the left hanging ear 8 and the right hanging ear 9 are L-shaped, one side of which is fixed on the left side plate 3 or the right side plate 4, and the other side is used to fix the entire measurement and control unit profile chassis.

[0033] like Figure 6 As shown, the new measurement and control unit profile chassis also includes a busbar mounting bar, and the busbar mounting bars are 2, including an upper busbar mounting bar and a lower busbar mounting bar, which are respectively fixed on the upper profile cover plate 1 and the lower profile cover plate 2.

[0034] like Figure 4 and Figure 5 As shown, the busbar mounting strip is fixed to the back of the chassis, and the upper profile cover plate 1 and the lower profile cover plate 2 are provided with busbar mounting strip fixing holes in the vertical direction of the guide groove 6. The upper busbar mounting strip and the lower busbar mounting strip are both L-shaped, and fixing holes are provided on both sides of the L-shaped strip. The upper busbar mounting strip is fixed to one side edge of the upper profile cover plate 1 through the fixing holes, and the lower busbar mounting strip is fixed to one side edge of the lower profile cover plate 2 through the fixing holes.

[0035] If the upper profile cover plate 1 and the lower profile cover plate 2 are both axisymmetric structures, the time to open the fixing holes of the busbar mounting strip does not affect the interchangeability of the upper and lower covers, that is, the fixing holes of the busbar mounting strip are also axisymmetrically arranged, or the fixing holes are opened after assembly; if the upper profile cover plate 1 and the lower profile cover plate 2 are not axisymmetric structures, one of the covers needs to be horizontally rotated 180 degrees to correspond to the other cover plate, and then a fixing hole is opened according to the position where the busbar mounting strip needs to be fixed, so as to fix the busbar mounting strip. That is, the fixing holes of the busbar mounting strip should be opened after assembly.
