Abstract
The utility model relates to a contact comprising a contact surface and a welding surface. The contact includes a contact segment, a middle segment and a welding segment, wherein the three segments are successively connected; 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 middle segment is cylindrical. The contact segment and the welding segment are in horn mouth shapes with one ends large and one ends small; the big end of the contact segment corresponds to the contact surface and the big end of the welding segment corresponds to the welding surface. 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, interlude and the welding section that links to each other successively, and the end face of described contact-segment is contact-making surface, and the end face of described welding section is solder side, described interlude is cylindricality, described contact-segment and welding section are the little toroidal of the large end of an end, and a larger end of described contact-segment is corresponding to contact-making surface, and a larger end of described welding section is corresponding to solder side.
Described interlude is cylindrical, and described contact-segment and welding section all are the horn mouth 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 the contact-segment that links to each other successively, interlude and welding section, the end face of described contact-segment is contact-making surface, the end face of described welding section is solder side, described interlude is cylindricality, described contact-segment and welding section are the little toroidal of the large end of an end, a larger end of described contact-segment is corresponding to contact-making surface, a larger end of described welding section is corresponding to solder side, so that increased in the relative prior art of the area of solder side and contact-making surface, more firm during welding, the appliance switch life-span is longer, because the area of welding and contact is larger, its conductivity is still good after the welding, interlude cross-sectional area less, make its economical with materials, cost.
Description of drawings
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, interlude; 5, 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, the contact of the present embodiment comprises contact-making surface 1 and solder side 2, and the contact comprises contact-segment 3, interlude 4 and the welding section 5 that links to each other successively, the end face of contact-segment 3 is contact-making surface 1, the end face of welding section 5 is solder side 2, and interlude 4 is cylindricality, and contact-segment 3 and welding section 5 are the little toroidal of the large end of an end, a larger end of contact-segment 3 is corresponding to contact-making surface 1, and a larger end of welding section 5 is corresponding to solder side 2.So that increased in the relative prior art of the area of solder side and contact-making surface, more firm during welding, the appliance switch life-span is longer, because the area of welding and contact is larger, its conductivity is still good after the welding, interlude cross-sectional area less, make its economical with materials, cost.
In the present embodiment, described interlude 4 is cylindrical, and contact-segment 3 and welding section 5 all are the horn mouth 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.
Claims (2)
