Abstract
The utility model relates to a contact terminal comprising a contact surface and a welding surface. A plurality of grooves are arranged on the welding surface and are staggered mutually to form a grid pattern. Therefore, the welding area is enlarged during the welding process, thereby enhancing the conductive performance. Besides, the grooves in the grid mode play a role in positioning, so that the contact terminal can be prevented from disengagement 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, comprises contact-making surface and solder side, and described solder side is provided with many grooves, and described groove is interlaced to be latticed.
Described groove is that two horizontal strokes two are perpendicular interlaced.
Contact described in the utility model, comprise contact-making surface and solder side, described solder side is provided with many grooves, described groove is interlaced to be latticed, so that solder side bonding area when welding increases, strengthen electric conductivity, latticed groove plays positioning action, 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, groove.
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 many grooves 3, and groove 3 is interlaced to be latticed.Described groove is interlaced to be latticed, so that solder side bonding area when welding increases, strengthens electric conductivity, and latticed groove 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 groove 3 is that two horizontal strokes two are perpendicular interlaced.The quantity of this design groove 3 is neither too much nor too little, and cost is lower, and plays preferably the effect of the firm contact in location.Certainly, also can be transformed to three horizontal three perpendicular groove or four horizontal four perpendicular grooves.
The utility model is not limited to above embodiment and conversion.
Claims (2)
1. a contact comprises contact-making surface (1) and solder side (2), and it is characterized in that: described solder side is provided with many grooves (3), and described groove (3) is interlaced to be latticed.
2. a kind of contact according to claim 1 is characterized in that: described groove (3) is two horizontal two perpendicular interlaced.
