Detailed Description

In order to further explain the technical means and technical effects of the present invention, the following embodiments are combined to explain the present invention in detail.

The utility model discloses a jack is including the reed 2 that is located the fixing ring 1 at jack both ends and is located a plurality of intervals setting between two fixing rings, and a plurality of reed structures between two fixing rings are the same and arrange the same, and interval between two adjacent reeds can equal also can the inequality. The middle of the reed is sunken towards the inside of the jack to form a contact part I3 which is used for being in close contact with a contact pin so as to realize the electrical connection of the contact pin jack, and the contact part I can be in point contact or surface contact with the contact pin 4.

The two ends of each reed are respectively connected with the fixing rings, after the jack is installed in the jack shell 5, the two fixing rings are limited by the limiting step 6 at the end part of the jack shell to prevent the jack from being separated from the plug pin when the jack is plugged, the two fixing rings of the jack are respectively contacted with the jack shell to form a contact part II and a contact part III, the reeds between the contact part II and the contact part I and between the contact part III and the contact part I are both of a concave-convex alternative structure, and when the jack is plugged with the plug pin, the reeds elastically expand and deform under the extrusion effect of the plug pin to enable the convex part of the concave-convex alternative structure to. When the jack and the contact pin are not inserted oppositely, the convex part of the concave-convex alternating structure is not contacted with the jack shell.

The reed between II and I and between III and I of contact site all is provided with the unsmooth structure in turn of a set of or multiunit, and unsmooth structure quantity in turn between II and the I of contact site and unsmooth structure quantity in turn between III and the I of contact site can equal also can be inequality.

Taking fig. 2-4 as an example, the springs between the contact part ii and the contact part i and between the contact part iii and the contact part i have a set of concave-convex alternating structures, and the springs elastically expand and deform under the pressing action of the contact pin so that the convex parts of the concave-convex alternating structures between the contact part ii and the contact part i contact with the jack housing to form a contact part iv 9. And the convex part of the concave-convex alternating structure between the contact part III and the contact part I is contacted with the jack shell to form a contact part V10. In the jack shown in fig. 2, two contact points, namely a contact part iv and a contact part v, are arranged between each spring leaf and the jack housing, and a contact part i is arranged between each spring leaf and the contact pin; a plurality of reeds with the same structure are fixed between the two fixing rings according to the same arrangement sequence to form the jack of the utility model. Contactless between the reed of original jack and the jack casing, only the holding ring at reed both ends is used for transmission current with the contact of jack casing, compares original jack, the utility model discloses a also form electric contact between jack reed and the jack casing, increased the contact point between the jack is whole and the jack casing, can increase the area of contact of jack and jack casing, reduce connecting resistance, increase current transmission volume, realize heavy current transmission to guarantee the stability of electricity connection simultaneously.
