Abstract
The utility model relates to the technical field of electromagnetic coils, in particular to a surge current prevention electromagnetic coil which comprises a framework and insulation rubber tape. A varnished wire coil is wound in the framework, and moreover the insulation rubber tape wraps the outer side of the varnished wire coil. The framework is provided with a magnetic head, a needle seat is arranged on the right side of the magnetic head, an inserting needle is arranged on the needle seat, and an insulation rubber layer covers the outer side of the magnetic head and the outer side of the needle seat. Insulation materials are adopted in the surge-current resistant electromagnetic coil, so that exposed wires can not be easily broken, the reliability of products is guaranteed, and the insulation materials are used at positions where the needle is exposed, so that tolerable instant 4000V surge currents between poles are guaranteed, the process is simple, operation is easy, and under the premise of not greatly increasing cost, the quality of the products is improved.
Description
Technical field
The utility model relates to solenoid technical field, especially a kind of Antisurge current solenoid.
Background technology
The situation that solenoid sometimes needs to bear high voltage in the process of using, current solenoid can not prevent that leakage switch is in actual application environment lightning protection etc., lower purpose of breaker failure, and cause the damage of personnel and equipment.
Utility model content
In order to overcome existing solenoid can not prevent from the leaking electricity deficiency of surge, the utility model provides a kind of Antisurge current solenoid.
The utility model solves the technical scheme that its technical problem adopts: a kind of Antisurge current solenoid, comprise skeleton and insulating tape, in described skeleton, be wound with enameled wire loop and enameled wire loop outside and be enclosed with insulating tape, described skeleton is provided with magnetic head, the right side of described magnetic head is provided with needle stand, described needle stand is provided with contact pin, and described magnetic head and needle stand outside adopt insulation glue-line to cover.
The beneficial effects of the utility model are, this Antisurge current solenoid employing adds insulating material and has guaranteed that exposed line is not easy to fracture, guaranteed the reliability of product, at exposed pin, place adds insulating material, thereby guaranteed to tolerate between the utmost point and the utmost point surge current of instantaneous 4000V, adopted this kind of technique simple, easy to operate, do not increasing under the prerequisite of very large cost, improving the quality of product.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure 1, skeleton, 2, contact pin, 3, needle stand, 4, magnetic head, 5, insulating tape.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of Antisurge current solenoid, comprise skeleton 1 and insulating tape 5, in described skeleton 1, be wound with enameled wire loop and enameled wire loop outside and be enclosed with insulating tape 5, described skeleton 1 is provided with magnetic head 4, the right side of described magnetic head 4 is provided with needle stand 3, and described needle stand 3 is provided with contact pin 2, and described magnetic head 4 and needle stand 3 outsides adopt insulation glue-line to cover.
This Antisurge current solenoid is installed magnetic head 4 and needle stand 3 on skeleton 1, and use insulation glue-line to cover, guaranteed to tolerate between the utmost point and the utmost point surge current of instantaneous 4000V, and employing adds insulating material and has guaranteed that exposed line is not easy to fracture, having guaranteed the reliability of product, is respond well.
