Abstract
The utility model discloses a contact device comprising a moving contact and a static contact, wherein the moving contact (1) is provided with a bare tip part (2); and the static contact (11) is provided with a sharp-angled notch (12) adaptive to the bare tip part (2). By adopting the moving contact and the static contact in the above structure, the contact area between the moving contact and the static contact is obviously increased during connection, therefore, the electricity conductivity is improved.
Description
The utility model relates to a kind of contact making device that is used for switch, relay and contactor.
Background technology
Existing conductive contact, its shape mostly are that two spheres are relative or two planes are relative; No matter be that two spheres are relative or two planes are relative, its contact area is all very limited.Because limited contact area has caused its resistance to increase the electric conductivity of influencing contactor.
Summary of the invention
The utility model provides a kind of contact making device that conducts electricity very well at above-mentioned deficiency.
The utility model is achieved in that a kind of contact making device, comprises moving contact and fixed contact, and described moving contact is provided with bald tip, and described fixed contact is provided with the pointed shape recess that adapts with this bald tip.
Adopt the moving contact and the fixed contact of said structure, when connecting, can improve the contact area between them significantly, thereby improve its electric conductivity.
Description of drawings
Fig. 1 is the structural representation of the utility model contact making device;
The vertical view of fixed contact among Fig. 2 Fig. 1;
Fig. 3 is the structural representation after contact making device shown in Figure 1 closes up.
Embodiment
Below in conjunction with accompanying drawing the utility model execution mode is described in further detail.
As shown in Figure 1 to Figure 3, contact making device comprises moving contact and fixed contact, and described moving contact 1 is provided with bald tip 2, and described fixed contact 11 is provided with the pointed shape recess 12 that adapts with this bald tip 2.Because the contact-making surface of above-mentioned moving contact 1 and fixed contact 11 is made into ramped shaped, can improve the contact area between them so significantly, thereby improve its electric conductivity.
Claims (1)
1. a contact making device comprises moving contact and fixed contact, it is characterized in that: described moving contact (1) is provided with bald tip (2), and described fixed contact (11) is provided with the pointed shape recess (12) that adapts with this bald tip (2).
