The jack base is cylindrical, and the claw spring leaf is installed in the contact port. The spring leaf can be fixed in the cylinder by its own elasticity or pressed into the cylinder. The elastic force of the spring leaf depends on the width, number, arc size and material of the elastic claw. This type of jack is characterized by multiple contact points, soft plugging and unplugging, and high mechanical life. It is widely used in aviation plugs of small and medium-sized connectors.

[0003] For example, the Chinese authorized patent with announcement number CN210779094U (a kind of elastic spring claw socket): includes a rear sleeve and a spring claw assembled in the socket of the rear sleeve, the socket of the rear sleeve is provided with a limiting step I for limiting the tail end of the spring claw and a trapezoidal limiting step II cooperating with the waisted part in the middle of the spring claw, the spring claw includes an end band and a plurality of elastic spring leaves connected to the end band and arranged at intervals, the middle part of the spring leaf is waisted, the tail end of the spring leaf expands outward relative to the waisted part in the middle of the spring leaf, the waisted part in the middle of the spring leaf is also provided with a protrusion protruding outward for increasing the reliability of the electrical connection between the spring claw and the rear sleeve, the tail end of the spring leaf is limited between the limiting step I and the trapezoidal limiting step II, the waisted part in the middle of the spring leaf is surrounded by the trapezoidal limiting step II and is limited by the trapezoidal limiting step II to prevent the spring claw from falling out when plugging and unplugging with the pin, so as to realize efficient assembly of the spring claw, save assembly time, and improve the plugging and unplugging life of the socket while meeting the reliability of electrical connection.

[0004] However, the spring claw socket in the above-mentioned prior art makes the hole opening elastic by punching a hole at the socket end, opening a piece and then closing the hole opening to achieve the purpose of connecting with the pin. In order to ensure the elasticity of the hole opening, the opening piece needs to have a certain length, which makes it difficult to reduce the volume of the product, affecting its practicality. Therefore, it does not meet the existing needs. In this regard, we propose a rear sleeve welding column spring claw socket with good contact. Utility Model Content
