Description

A crown spring hole socket connection device

technical field

The invention relates to a crown spring hole socket connection device, which belongs to the technical field of connectors.

Background technique

Connectors are one of the key technologies for signal transmission, and there are many types of common connectors. Some types of connectors have problems such as complex structure, bulky size, and high cost. In connector products that have strict requirements on product volume and product cost (such as connectors used in complex chassis and individual cells in battery packs) connectors used between batteries) are not suitable.

The crown spring hole connector is a new type of connector developed on the basis of the existing slotted hole of the same type. This type of connector makes up for the problems of complicated processing of the slotted hole connection and burrs in the slot. However, the existing crown spring socket connectors need to use equipment to shrink the slot, and the separation force of the socket through the slot shrinkage is uneven, and at the same time, another component, the protective tube, is required to be crimped together to form the socket joint. Parts, in the process of slotting, shrinking, and crimping into socket fittings, there are quality problems caused by many uncertain factors and pain points of unstable performance.

Contents of the invention

The object of the present invention is to provide a crown spring hole socket connection device with simple structure, convenient manufacture and low cost, so as to overcome the deficiencies in the prior art.

The technical solution of the present invention: a crown spring hole socket connection device, including an insulating base and jacks opened on the insulating base, the jacks are stepped holes, and pins are pressed into each jack , A mounting hole is opened on the pin, a crown spring is pressed into the mounting hole, and a limiting part is set at the mouth of the mounting hole.

Further, the limiting part is a circle of arc-shaped protrusions, constrictions or flanges arranged on the inner wall of the installation opening.

Further, two rows of jacks are arranged on the insulating base.

Further, the crown spring is in an interference fit with the mounting hole.

Further, the lower end of the insulating base is fixedly connected to the insulating plate through screws, and the lower end of the pin protrudes from the through hole on the insulating plate.

Due to the adoption of the above technical solution, the advantages of the present invention are: the pins and the crown springs of the present invention are produced in batches, and the size is uniform, the force is uniform, and the crown spring is prevented from loosening by the limit part after the socket is loaded into the crown spring , and the limit part has a simple structure and reliable performance; and the crown spring can make the separation force of the pins uniform, reliable contact, low cost, no burr, higher performance index and reliability, suitable for aviation, aerospace, national defense and other fields .
