A kind of brushing needle contact, including male end component and female end component, male end component and female end component include casing, insert
Needle, contact pin is inside by six roots of sensation beryllium copper silk around, and an intermediate beryllium copper silk direction arbitrarily forms, and the beryllium copper silk of male end component stretches out set
Pipe；The beryllium copper silk of female end component is located in casing,
The contact portion of adjacent beryllium copper silk is provided with the first guide groove on the male end component, and adjacent beryllium copper silk upper two
One guide groove forms second guide groove；
The internal surface of sleeve pipe of the female end component, which is equipped with, plugs together area, and described plug together is uniformly arranged there are six third guide groove in area,
The surface of third guide groove is coated with slip coating.
The working principle of the utility model are as follows: during plug, radial and axial elastic deformation, mother all occur for beryllium copper silk
Beryllium copper silk on the component of end is uniformly interted by the guiding of the second guide groove on male end component, avoids the interspersed middle hair of beryllium copper silk
Bending deformation is sent, non-uniform problem is interted；Beryllium copper silk is closely contacted with each other to form electricity under the constraint of casing after mutually interting
Gas connection, wherein slided in the third guide groove for plugging together area that beryllium copper silk is scheduled on gradient and casing with one, the surface of third guide groove applies
There is slip coating, reduce frictional force, reduces the spoilage of beryllium copper silk.
The utility model has the following advantages and benefits:
1, the contact portion of a kind of brushing needle contact of the utility model, the adjacent beryllium copper silk on male end component is equipped with first
Guide groove, the first guide groove on adjacent beryllium copper silk form the second guide groove；In inserting process, the beryllium copper silk on female end component is by
Two guide grooves guiding is also able to maintain good contact after repeatedly interting so that beryllium copper silk uniformly interts.
2, a kind of brushing needle contact of the utility model, plugging together on the female end component are evenly arranged with seven on the inner wall in area
A third guide groove, the coating that the surface of third guide groove is coated with convenient for sliding；Frictional force is reduced, in inserting process, beryllium copper silk is with one
Fixed gradient is slided in the inner wall of casing, and frictional force is small, is hardly damaged beryllium copper silk.
