Abstract
The invention discloses an anti-electric-shock joint used for a discharge test of a small-capacity storage battery pack. The anti-electric-shock joint comprises a discharging instrument wiring terminal and a storage battery wiring terminal. The discharging instrument wiring terminal comprises an outer insulation sleeve and an inner insulation sleeve. The storage battery wiring terminal also comprises an outer insulation sleeve and an inner insulation sleeve. Each outer insulation sleeve and the corresponding inner insulation sleeve are matched in a sleeved mode. An annular interlayer cavity exists in the discharging instrument wiring terminal, and an insulation bevel plug forms on the storage battery wiring terminal. A storage battery end conductive tube is sleeved inside the inner insulation sleeve of the storage battery end. A discharging instrument end conductive tube and the storage battery end conductive tube are respectively connected to corresponding conductive wires. According to the joint of the invention, use of an insulating housing on the outside of a conductor avoids the occurrence of a spark when a clip is secured to a fuse pedestal and prevents the occurrence of an electric shock. Internal conductors of two joints are circular conductors. The contact area of each conductor is large, thereby guaranteeing good contact of the conductors. Through mutual engagements of the two joints in a concave and convex mode, shaking of the joints in a butt joint process is avoided. The processing technology is simple; the cost is relatively low; the installation and maintenance is convenient; and personal safety is guaranteed.
