Abstract
The utility model relates to a contact that comprises a contact surface and a welding surface. The contact includes a contact segment and a welding segment, wherein the two segments are connected into one; and the end surface of the contact segment is the contact surface and the end surface of the welding segment is the welding surface. Besides, the contact segment has a cylindrical shape. The welding segment is in a horn mouth shape with one end large and one end small; the big end of the horn mouth shape corresponds to the welding surface and the small end of the horn mouth shape corresponds to the contact segment. Therefore, compared with area of the welding surface in the prior art, the area of the welding surface is enlarged, so that firmness is realized during the welding; and the electric switch has a long service life. The electric conductivity of the contact is good after the welding due to the large welding area.
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 the sound contact, and the point that the sound contact is in contact with one another is commonly referred to as the contact, is also referred to as the 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 the contact comprises contact-making surface and solder side, and the contact is welded on the body of sound contact by solder side.
The area of existing contact solder side generally all is the same with contact-making surface large, bonding area is less during welding, not very firm after the welding, so that the contact easily comes off when colliding with, cause appliance switch to be affected, the appliance switch life-span is shorter, because area is less, welding can make its electric conductivity be affected.
The utility model content
Problem to be solved in the utility model is to improve the problem that the contact easily comes off in the background technology.
In order to overcome the above problems, the utility model provides a kind of contact, comprise contact-making surface and solder side, described contact comprises contact-segment and the welding section that connects as one, and the end face of described contact-segment is contact-making surface, and the end face of described welding section is solder side, described contact-segment is cylindricality, described welding section is the little toroidal of the large end of an end, and a larger end of described toroidal is corresponding to solder side, and a less end of described toroidal is corresponding to contact-segment.
Described contact-segment is cylindrical, and described welding section is the toroidal of the little circle of the large end of an end.
Contact described in the utility model, comprise contact-making surface and solder side, described contact comprises contact-segment and the welding section that connects as one, the end face of described contact-segment is contact-making surface, the end face of described welding section is solder side, described contact-segment is cylindricality, described welding section is the little toroidal of the large end of an end, a larger end of described toroidal is corresponding to solder side, and a less end of described toroidal is corresponding to contact-segment, so that increased in the relative prior art of the area of solder side, more firm during welding, the appliance switch life-span is longer, because bonding area is larger, its conductivity is still good after the welding.
Description of drawings
Accompanying drawing 1 is contact described in the utility model schematic diagram
Accompanying drawing 2 is schematic diagrames of another angle of contact described in the utility model
1, contact-making surface; 2, solder side; 3, contact-segment; 4, welding section.
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 the present embodiment, as shown in Figure 1, the contact of the present embodiment, comprise contact-making surface 1 and solder side 2, the contact comprises contact-segment 3 and the welding section 4 that connects as one, and the end face of contact-segment 3 is contact-making surface 1, and the end face of welding section 4 is solder side 2, contact-segment 3 is cylindricality, welding section 4 is the little toroidal of the large end of an end, and a larger end of toroidal is corresponding to solder side 2, and a less end of toroidal is corresponding to contact-segment 3.So that increased in the relative prior art of the area of solder side, more firm during welding, the appliance switch life-span is longer, because bonding area is larger, its conductivity is still good after the welding.
In the present embodiment, described contact-segment 3 is cylindrical, and welding section 4 is the toroidal of the little circle of the large end of an end.This design is so that the contact is convenient to processing more, and is also more attractive in appearance.
The utility model is not limited to above embodiment and conversion.
