Fasteners are generally standard components, including common screws, nuts, rivets, pull rivets, pre-tensioned adjustable clamp nuts, pre-tensioned locking nuts, and self-tapping screws. There are also specialized fastening screws (such as most low-pressure cabinets imported from abroad use specialized fastening screws). Technical features: shaped by fixtures, positioned by jigs, and pressure washers are added as needed; riveting usually requires drilling, and pre-plated parts must prevent the plating from being damaged; for components processed with precision or specialized equipment, such as when the connecting hole diameters and fastener diameters can maintain a slight gap, assembly without fixtures can be done for one-time forming; for the fastening of guide and positioning parts, specialized gauges should be used for initial positioning, followed by standard tooling for inspection.

The technical features of the drawer-type low-voltage cabinet are: (1) The fixed and removable parts must have a unified reference standard; (2) The relevant parts must be adjusted to position, and a special standard tooling should be used during adjustment, including standard cabinets and drawers; (3) The error of critical dimensions cannot exceed the tolerance; (4) The interchangeability of drawers of the same type and specification must be reliable. Regarding the connection methods: (1) Welding: Its advantages are convenient processing and reliable strength; disadvantages include large errors, easy deformation, difficult adjustment, and lack of aesthetics, and the workpieces are generally not pre-plated. Additionally, certain requirements are placed on the welding fixture: ① It must be rigid and not affected by workpiece deformation; ② The outer dimensions should be slightly larger than the nominal dimensions of the workpiece to compensate for the shrinkage after welding; ③ It should be flat, simple, and easy to operate, with a minimum of rotating mechanisms to avoid jamming; ④ To prevent welding corrosion and facilitate inspection and adjustment, a suitable workpiece support should be chosen, and anti-welding corrosion pads should be added. The deformation of the workpiece after welding is caused by the expansion of molecules at the welding point due to heating, resulting in microscopic displacement when compressed, and the inability to return to its original position after cooling due to stress. To overcome the effects of deformation, the shaping process must be considered.

The closing stroke does not include the pre-compression range of the closing spring; it is actually the second compression stroke of the closing spring. The closing speed and average closing speed mainly affect the electrical erosion of the contacts. If the closing speed is too low, the pre-breakdown time is long, the arc exists for a longer period, the surface erosion of the contacts is significant, and it may even cause the contacts to weld and stick together, reducing the electrical lifespan of the arc extinction chamber. However, if the speed is too high, it is prone to produce a closing bounce, and the output work of the operating mechanism also needs to be increased, resulting in a large mechanical impact on the arc extinction chamber and the entire machine, affecting the product's reliability and mechanical lifespan. The average closing speed is usually around 0.6 m/s.
