Description

Technical Field

[0001] The utility model relates to the technical field of cable connectors, in particular to a quick two-way connector. Background Art

[0002] In the existing electrical equipment such as switch cabinets, when the cables are connected, cable quick plugs are usually installed on the two cable ends that need to be connected, and correspondingly, a quick two-way connector used for plugging the two cable quick plugs is involved, that is, the two cable ends are respectively connected to the cable quick plugs, and then the conductive plugs of the cable quick plugs are respectively plugged into one end of the quick two-way connector, so as to realize the electrical connection between the two cable ends.

[0003] The existing quick two-way connector realizes electrical transmission through the conductive plug contacting the wall of the conductive tube inside the quick two-way connector after being plugged in with the conductive plug of the cable quick plug. However, in actual use, if the operator uses the quick two-way connector due to operating habits or improper operation, the following situations may occur: causing tilted installation (i.e., the conductive plug of the cable quick plug is not fully inserted or inserted crookedly), there is a probability that there is only point contact or a very small contact surface between the conductive plug and the wall of the conductive tube, which is easy to cause poor internal contact; although some solutions provide a spring sheet in the conductive tube, the spring sheet has a thin structure and general resilience. After frequent plugging and unplugging of the conductive plug, the elastic force of the spring sheet will weaken or even fail, so the electrical conductivity performance is still affected.
