The fuse holder is a protection circuit device with a wide range of applications, easy installation and high precision, and is accepted by the majority of users! The fuse holder is divided into two modes: one is printed circuit board soldering and linear cable terminal soldering, and the other is composed of control board drilled screws.
Have you encountered the deformation of the fuse holder? What if I encounter it?
In the development of different automation industries, there is a relatively large differentiation. Various factors should be considered comprehensively when selecting a fuse holder for circuit protection components. Here are the main factors to consider.
1. Vibration resistance and stability: Stability refers to the performance without self-excited vibration under given operating conditions; anti-vibration characteristics refer to the module's ability to accept forced vibration and shock.
2. The rigidity of the fuse holder is particularly important for precision machinery and instruments. The deformation of the module includes the deformation of the guide rail body and the contact extrusion deformation of the guide rail pair.
3. Motion Sensitivity and Positioning Accuracy The motion sensitivity of a linear guide is the minimum stroke that the moving part can achieve. Positioning accuracy refers to the ability of the moving part to stop at a specified position as needed. Motion sensitivity and positioning accuracy are related to factors such as track type, friction characteristics, motion speed, transmission stiffness, and quality of moving parts.
4. Thermal deformation of fuse holder bracket, etc. The choice of raw materials of fuse directly affects the working stability of the product, and the parts are easily deformed and fall off due to the materials that are not resistant to high temperature.
5. The motion stability of the motion stability module is the performance that the guide rail does not crawl at low speed or slight movement. The stability is related to the structure and other factors of the guide rail.
Fuse holder name:
Fuseholders are designed and developed for better installation and replacement of individual fuses, which are known in the industry as fuseholders. Of course, there are also fuse boxes, fuse clips, fuse sleeves, fuse holders and other products of the same type.
Classification of fuse holders:
From a few years ago to now, fuse holders can be divided into: panel mount fuse holders, printed circuit board (hard) board fuse holders, automatic plug-in fuse holders and plug-in fuse holders.
Electrical characteristics of fuse holder:
The fuse holder should include the requirements of withstand current, voltage, high temperature and fire rating. These factors mainly depend on the quality of the plastic and metal parts of the fuse holder. The better the quality, the higher the temperature resistance coefficient. Since the fuse holder 3C is not mandated to be certified, some fuse holders are basically not certified by 3C!
Fuse holder material:
The fuse box is more troublesome in the production and manufacturing process. The market price is much higher than the price of fuses, fuses and fuse holders. Same thing. When the plastic parts and hardware raw materials are of good quality, the price is also relatively high. Now they can generally be divided into plastic parts, phenolic nylon PA66, polypropylene material, plastic, hardware, brass nickel plated, silver plated or brass. The preferred material is tin copper tin silver electroplating.
Fuseholder transient and leakage currents for ESD currents of circuit board integrated circuits data lines. Electrostatic discharge transitions for electrical equipment reduce the electrostatic discharge current directly into the chip through the data lines of the protected data line substrate integrated circuit. ESD suppressors for electronics clamp transients, thereby limiting the ESD current to the chip.
