Safety joint for experimental wire connection

Abstract

A safety joint for experimental wire connection comprises a lantern-typed plug matched with a conductive metal hole and a connecting wire for connecting the lantern-typed plug. The safety joint for experimental wire connection further comprises an external insulating cylinder, a spring and an internal insulating cylinder. The external insulating cylinder is located outside the lantern-typed plug and is integrally formed with the lantern-typed plug, the internal insulating cylinder wraps the lantern-typed plug exposed outside the external insulating cylinder and is arranged in the inner cavity of the external insulating cylinder, the internal insulating cylinder can slide along the inner cavity of the external insulating cylinder, the spring is arranged between the upper end face of the internal insulating cylinder and the external insulating cylinder, a slide is arranged in the inner cavity of the external insulating cylinder, and a bead matched with the slide is arranged on the outer wall of the internal insulating cylinder. The joint is safe and reliable in use and can totally avoid the damage of short out to a circuit caused by careless operation, and a connection hole button which has existed in a circuit board dose not need to be modified, so that the safety joint for experimental wire connection is low in cost for popularization and use, and easy to achieve, improves the utilization rate of experimental equipment, and reduces the maintenance charge of the equipment.

Description

technical field [0001] The invention relates to circuit experiment connection lines, in particular to a safety connector for experiment connection lines. Background technique [0002] In many experimental circuits, in order to allow students to recognize the appearance of electronic devices and facilitate testing, many experimental circuit boards deliberately install components and conductive metal hole buttons (hereinafter referred to as hole buttons) for wiring plugs. On the top of the circuit board, students can observe and learn various circuit functions by connecting these different hole buttons with wires. For the convenience of connection operation, the common conductive metal columnar plugs for connecting wires are directly exposed. A little carelessness in operation will cause accidental short circuit events. The most common accidental short circuit has three situations: first, a single metal plug accidentally touches two conductive points on the circuit board at ...
