Abstract
The utility model relates to a contact terminal for a switch. The contact terminal comprises a contact surface and a welding surface. A circular recessed structure is arranged on the welding surface. The circular recessed structure enables the welding surface to be enlarged during the welding process, so that the conductivity is enhanced. Besides, the circular recessed structure can play a role in positioning, so that the disengagement of the contact terminal can be prevented when the contact terminal is knocked and thus the electric switch has a long service life.
Description
Technical field
The utility model relates to a kind of contact.
Background technology
All be provided with switching device in a lot of electrical equipment.Especially itself realize switch control, such as circuit breaker, its switch generally is comprised of dynamic/static contact, and the point that dynamic/static contact is in contact with one another is commonly referred to as the contact, is also referred to as contact.This contact is generally made by silver and some other metal materials, has to conduct electricity very well, and is not easy to cause the advantage of electric spark.The shape of contact generally is exactly a dot, and contact comprises contact-making surface and solder side, and contact is welded on the body of dynamic/static contact by solder side.
Existing contact solder side all is level generally, and bonding area is less and too level and smooth during welding, so that contact comes off when colliding with easily, causes appliance switch to be affected, and the appliance switch life-span is shorter.
The utility model content
Problem to be solved in the utility model is to improve the problem that contact comes off easily in the background technology.
In order to overcome the above problems, the utility model provides a kind of contact for switch, comprises contact-making surface and solder side, and described solder side is provided with the circular depressed structure.
Described circular depressed number of structures is one, the center of circle of circular depressed structure be positioned at the center of solder side.
Described solder side is circular, and the center of circle of described circular depressed structure is positioned at the center of circle of solder side.
A kind of contact for switch described in the utility model, comprise contact-making surface and solder side, described solder side is provided with the circular depressed structure, the circular depressed structure is so that solder side bonding area increase when welding, strengthen electric conductivity, the circular depressed structure plays positioning action, and contact is not easy to come off when colliding with, and the appliance switch life-span is longer.
Description of drawings
Accompanying drawing 1 is contact schematic diagram described in the utility model
Accompanying drawing 2 is schematic diagrames of another angle of contact described in the utility model
1, contact-making surface; 2, solder side; 3, circular depressed structure.
Embodiment
Below in conjunction with accompanying drawing a kind of contact of the utility model is described further.
As shown in Fig. 1, Fig. 2, the contact of present embodiment comprises contact-making surface 1 and solder side 2, and solder side is provided with circular depressed structure 3.Described circular depressed structure 3 strengthens electric conductivity so that solder side bonding area when welding increases, and circular depressed structure 3 plays positioning action, and contact is not easy to come off when colliding with, and the appliance switch life-span is longer.
In the present embodiment, described circular depressed structure 3 quantity are one, and the center of circle of circular depressed structure 3 is positioned at the center of solder side 2.This design is so that processing circular depressed structure 3 quantity are few, and processing cost is lower.Described circular depressed structure 3 can be one, also can two even a plurality of.
In the present embodiment, described solder side 2 is circular, the center of circle of circular depressed structure 3 be positioned at the center of circle of solder side 2.This design is so that contact processing is more reasonable, and shape is more attractive in appearance.
The utility model is not limited to above embodiment and conversion.
Claims (3)
1. a contact that is used for switch comprises contact-making surface (1) and solder side (2), and it is characterized in that: described solder side is provided with circular depressed structure (3).
2. a kind of contact for switch according to claim 1, it is characterized in that: described circular depressed structure (3) quantity is one, the center of circle of described circular depressed structure (3) is positioned at the center of solder side (2).
3. a kind of contact for switch according to claim 2 is characterized in that: described solder side (2) is for circular, and the center of circle of described circular depressed structure (3) is positioned at the center of circle of solder side (2).
