A lockable high current pin jack assembly

Abstract

The invention belongs to the field of electrical contact and relates to a lockable large current pin jack assembly. A lockable high current pin socket assembly of the present invention includes a socket with an annular projection and a pin with an annular slot. The needle end of the pin is provided with an annular groove, the left side surface of the groove and the right side surface of the grooveare conical surfaces; The insertion end of the insertion hole of the invention is slotted to open the insertion end of the insertion hole into n lobes, and the inner hole of the insertion end is provided with an inward annular protrusion, which is in contact with the annular groove arranged on the pin head to form the contact of the conical surface of the 2n lobes. When the socket assembly of theinvention is in use, the socket and the pin are inserted into the position to have a feeling of hand and have a locking function; and when the socket assembly of the invention is in use, the socket and the pin are inserted into the position. The inner hole of the socket is provided with an inward annular protrusion, which is in contact with the outer diameter annular groove arranged on the pin head to form surface contact, has large contact area and strong through-load capacity, solves the problem of large current load, and is suitable for operation of narrow space due to short separation distance when pulling out.

Description

technical field [0001] The invention belongs to the field of electric contact, and relates to a lockable high-current pin socket assembly. Background technique [0002] Open jacks are used with pins. The open socket adopts the method of mechanical processing. Firstly, the hole is drilled (the diameter of the hole is slightly larger than the diameter Фd of the pin), slotted, and then closed, so that the front end of the socket is deformed inward, and then the final shape of the open socket is obtained. shape. When the pin is inserted, the front end of the opening jack cooperates with the outer diameter of the pin to conduct current. The open socket forms a four-point contact with the contact pin, the contact area is small, and the ability to conduct current is limited. In addition to the limited conductivity, due to the characteristics of the open socket, the positive pressure is large, the insertion force is large, and it is easy to wear; and in the case of a narrow opera...
