Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a technical solution:

the utility model provides a compact jack contact, includes contact 1, and 1 outside has been offered jack 3 for shell 2 and inside for contact 1, mounting hole 4 has been seted up at 3 tops of jack, 4 inner wall both sides tops of mounting hole are all fixed and are provided with turn over strake 5, the inside activity of mounting hole 4 is provided with reed 6, and the mounting hole 4 matches grafting and the 4 degree of depth of mounting hole is higher than reed 6 height with reed 6 size, and reed 6 includes sharp end 601, cambered surface 602 and shell fragment 603.

The diameter of the jack 3 is smaller than that of the mounting hole 4, the top of the jack 3 is communicated with the bottom of the mounting hole 4, and the contact pin is inserted into the jack 3 through the mounting hole 4.

The junction of the jack 3 and the mounting hole 4 is in a step shape, so that the reed 6 can be conveniently mounted in the mounting hole 4 and cannot fall into the jack 3.

The size of the mounting hole 4 is matched with that of the reed 6, the mounting hole 4 is inserted and connected, and the depth of the mounting hole 4 is higher than that of the reed 6, so that the reed 6 is completely installed in the mounting hole 4.

The reed 6 comprises a linear end 601, an arc surface 602 and elastic sheets 603, the linear end 601 is arranged at each of the two ends, the arc surface 602 is arranged in the middle, the plurality of elastic sheets 603 are uniformly arranged on the surface of the arc surface 602, and the direction of the elastic sheets 603 is the same as the direction of the arc surface 602, so that a pin can be conveniently and fixedly clamped with the pin through the elastic sheets 603 when the pin is inserted.
