Abstract
The utility model relates to a security-protection alarming electromagnetic device, in particular to a security-protection alarming large and small-head electromagnetic device, which comprises a framework, a strip-shaped magnet, a coil and a capacitor, wherein the framework is sleeved on the strip-shaped magnet, the coil is wound on the framework, and both ends of the coil are connected in parallel with the capacitor. The security-protection alarming large and small-head electromagnetic device is characterized in that: one end of the strip-shaped magnet is integrally provided with a large-head magnet, so that the whole magnet is formed into a structure with a large head and a small head; the strip-shaped magnet and the large-head magnet are respectively made of a manganese-zinc material; the framework is made of an ABS (Acrylonitrile Butadiene Styrene) material; and the capacitor is a CBB11-type polypropylene-film capacitor. Because the volume of the whole magnet is enlarged through the large-head magnet, the Q value of the whole magnet is increased, the Q value of the electromagnetic device is also increased therewith, the alarming distance of the electromagnetic device on access control is longer, the security-protection effect is better, and the requirements of a client are met.
Description
Technical field
The utility model is a kind of security alarm calutron, particularly a kind of security alarm concentric reducer calutron.
Background technology
Existing security alarm calutron as shown in Figure 1, it comprises skeleton 1, bar-shaped magnet 2, coil 3 and capacitor 4, be socketed with skeleton 1 on the bar-shaped magnet 2, be wound with coil 3 on the skeleton 1, the two ends of coil 3 also are connected to capacitor 4, because bar-shaped magnet 2 is elongated strips, so cause calutron Q value low, alarm distance is near, can not satisfy client's demand.
Summary of the invention
The purpose of this utility model is in order to overcome the low near defective of alarm distance of existing security alarm calutron Q value, to invent a kind of security alarm concentric reducer calutron that Q value and alarm distance all is improved by the change to magnet structure.
The purpose of this utility model realizes as follows: described security alarm concentric reducer calutron, comprise skeleton, bar-shaped magnet, coil and capacitor, be socketed with skeleton on the bar-shaped magnet, be wound with coil on the skeleton, the two ends of coil also are connected to capacitor, it is characterized in that: an end of described bar-shaped magnet is provided with the major part magnet integratedly, thereby allows whole magnet form a big little structure.
Described bar-shaped magnet and major part magnet are by the MnZn material.
Described skeleton is by the ABS material.
Described capacitor is poly-third membrane capacitance of CBB11 type.
Good effect of the present utility model is as follows: because the major part magnet enlarges the volume of whole magnet, the Q value of whole magnet is improved,, make its alarm distance on the gate inhibition farther so the Q value of calutron also improves thereupon, the security protection effect is better, has satisfied client's demand.
Description of drawings
Fig. 1 is existing security alarm calutron structural drawing
Fig. 2 is the utility model structural drawing
Among the figure: 1 skeleton, 2 bar-shaped magnets, 3 coils
4 capacitors, 5 major part magnets
Embodiment
As shown in Figure 2, described security alarm concentric reducer calutron, comprise skeleton 1, bar-shaped magnet 2, coil 3 and capacitor 4, be socketed with skeleton 1 on the bar-shaped magnet 2, be wound with coil 3 on the skeleton 1, the two ends of coil 3 also are connected to capacitor 4, it is characterized in that: an end of described bar-shaped magnet 2 is provided with major part magnet 5 integratedly, thereby makes whole magnet form a big little structure.
Described bar-shaped magnet 2 and major part magnet 5 are by the MnZn material.
Described skeleton 1 is by the ABS material.
Described capacitor 4 is poly-third membrane capacitance of CBB11 type.
Because the major part magnet enlarges the volume of whole magnet, the Q value of whole magnet is improved, so the Q value of calutron also improves thereupon, make its alarm distance on the gate inhibition farther, the security protection effect is better, has satisfied client's demand.
