Description

A low contact resistance rivet type electrical contact

technical field

The utility model belongs to an electric contact connecting two electric components.

Background technique

Due to the small contact area of the existing electric contacts, poor contact is easy to occur, and the cross-sectional area of the contacts is small due to the small size of the contacts, so that the resistance of the contacts is extremely large and the loss of electric energy is large.

Contents of the invention

The purpose of the utility model is to provide a rivet type electric contact with low contact resistance for the existing electric contacts which are prone to poor contact and large resistance.

The utility model is achieved through the following technical solutions:

A low contact resistance rivet-type electrical contact, including a rivet-type conductor, has a plurality of raised cylinders on the conductor, and a contact is integrally connected to the upper end of each cylinder, and the upper end of each cylinder The contacts are all coated with a silver contact layer, and the lower end of each column is connected to a rivet-shaped conductor through a metal conductive elastic device. There are at least three pillars, and each pillar is distributed in an array. Each of the contacts is a spherical or hemispherical structure. The metal conductive elastic device is a metal conductive shrapnel or a metal conductive spring.

Beneficial effects of the utility model: the utility model is simple in structure, adopts a plurality of contact points to contact with the object to be contacted, so that the contact area is increased, the resistance is small, and the design of multiple contacts is designed as an elastic auxiliary structure so that it does not Poor contact will occur, strong practicability.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with embodiment the utility model is further described.

Example

As shown in Figure 1, a low contact resistance rivet-type electrical contact, including a rivet-type conductor 1, has a plurality of raised columns 2 on the conductor 1, and the upper ends of each column 2 are uniformly connected There is a contact 3, and the contact 3 on the upper end of each cylinder 2 is coated with a silver contact layer 4, and the lower end of each cylinder 2 is connected to the rivet type conductor 1 through a metal conductive elastic device 5. There are at least three columns 2, and each column 2 is distributed in an array. Each of the contacts is a spherical or hemispherical structure. The metal conductive elastic device is a metal conductive shrapnel or a metal conductive spring. When in use, the contacted object is in contact with each contact, and the contacted object has a downward pressure on each contact, and at the same time, the column presses down on the metal conductive elastic device, so that the metal conductive elastic device has an upward force on the column. Push force, so that each contact can be in good contact with the contacted object without poor contact.

The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the description is only to illustrate the principle of the utility model. Simple modifications and replacements by ordinary technicians are within the protection scope of the present utility model.
