Detailed Description
Example one
The structure of the embodiment is shown in fig. 1-9, and the secondary contact mounting structure of the drawer unit of the low-voltage cabinet comprises two groups of secondary terminal assemblies which are arranged on the right side plate of the drawer in a side-by-side and front-and-back position mode. The secondary terminal assembly comprises a secondary terminal moving part 1-1 and a secondary terminal moving part 1-2 which are arranged on a drawer right side plate moving part 1, and a secondary terminal fixing part 2-1 and a secondary terminal fixing part 2-2 which are arranged on a drawer right side plate fixing part 2. The front and the rear groups of terminals are installed through the secondary terminal moving part clamping grooves 1-1-1 and the secondary terminal moving part clamping grooves 1-2-1 which are designed by the front and the rear groups of terminals, and can be fixed without self-tapping screws. The moving part 1 and the fixed part 2 of the right side plate of the drawer are both provided with an opening 3 matched with the shape of a slot of the secondary terminal assembly. Opening 3's below is equipped with the trompil 4 in advance the same rather than external profile, and trompil 4 is the hole structure that can knock off in advance, and drawer right side board removes partial sheet metal component when the design, and 2 secondary terminals of group can be installed to the trompil part, and the hole structure that can knock off is designed to the lower part, presets two sets of installation space, can knock off according to the project demand. After knocking, 4 groups of secondary contacts can be installed on a single drawer. The moving parts of the two sets of secondary terminals after being installed protrude out of the right side plate of the drawer moving part 1, and a height difference exists between the two protruding sets of secondary terminals. The height difference is gradually reduced along the moving direction of the drawer. The secondary terminal moving part and the fixed part are structurally provided with two clamping grooves, the sizes of the holes formed in the mounting plate are different according to the different positions of the secondary terminal clamping grooves, a height difference of 11mm exists in the right side protruding part of the right side plate of the drawer moving part 1 after the secondary terminal moving part is mounted, the secondary terminal mounted on the side plate is different in clamping position through the difference of the front fixed terminal hole and the rear fixed terminal hole on the side plate, and the secondary terminal mounted on the side plate can be ensured not to be at the same height when mounted on the side plate. In the drawer cabinet, a drawer right side plate fixing plate is arranged on the cabinet body and does not move along with the drawer. The secondary terminal fixing part is arranged on the right side plate fixing plate of the drawer, and the secondary terminal fixing part 2-1 and the secondary terminal fixing part 2-2 are also arranged side by side and at the front and back positions. The front and the rear groups of terminals are installed through self-designed clamping grooves 2-1-1 and 2-2-1, can be fixed without self-tapping screws, and have a height difference at a left protruding part of a fixing part of a right side plate of the drawer after the installation is finished. The same secondary terminal is different according to draw-in card position and mounting panel trompil size, has a difference in height of 8.5mm after secondary terminal fixed part installation is accomplished, and secondary terminal fixed part left side protrusion size before being close to the cabinet will be little than the secondary terminal protrusion size behind the cabinet, is to avoid the secondary terminal moving part of fore-and-aft position to move the in-process and bump with it at the drawer. Drawer right side board fixed part sheet metal component structure according to 4 secondary terminals of mountable of actual design demand, goes up two sets ofly and two sets of down, but the sheet metal structure lower part is the structure of pounding. And selecting whether to knock off or not according to different requirements. The fixed parts of the two sets of secondary terminals after installation protrude out of the left side of the right side plate of the drawer fixed part 2, and a height difference exists between the two protruding sets of secondary terminals. The height difference is gradually increased along the moving direction of the drawer. When the drawer is pulled out and pushed in, because the secondary terminal moving part and the secondary terminal fixing part have a height difference relationship, the drawer can not be contacted in the pushing and pulling processes, and the drawer can be stably pulled out. The matching mode of the movable plug-in and the static plug-in of the secondary terminal assembly is the plug-in matching, the flaky copper sheets are contacted, the contact surface is large, and the electrification is ensured to be more stable.
The secondary terminal assembly is arranged on the right side of the drawer, self-tapping screws are not needed for installation, at most 4 groups of secondary contacts can be installed, the structure is divided up and down, installation space is saved, and space is saved for installing more components in the drawer. According to the difference of the structures of the mounting plate and the contacts, the same contacts have height difference after being mounted at different positions in the front and the back, when the drawer is pulled out and pushed in, because the secondary terminal moving part 1 and the secondary terminal fixing part 2 have the height difference, the contact cannot be generated in the pushing and pulling processes, the situation that the pulling and pushing of the drawer are not influenced after the plurality of groups of contacts are mounted is ensured, and the drawer can be pulled out and pulled out stably. The mounting structure is simple, and automatic snap-in formula saves time and does not occupy the drawer inner space, and the mounted position is multiple, and is different according to the different secondary contact mounted position of mounting panel trompil size. Meanwhile, the secondary terminal moving part and the fixed part are contacted through the sheet copper sheet, so that the contact surface is large, and the electrification is ensured to be more stable.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
