Embodiment 1

[0023] A high-safety hot-swappable low-voltage power supply interface, installed on the housing of the power supply equipment, such as figure 1 As shown, this embodiment includes a hot-swappable plug and a socket. The hot-swappable plug includes an insulating sleeve 12, metal contacts and outgoing wires 11, and the metal contacts are connected to the outgoing wires 11. The metal contacts and the outgoing wires 11 are installed on On the insulating sleeve 12, the socket includes an insulating shell 21, a metal contact sleeve 22 and a stem 25. The front part of the metal contact sleeve 22 is processed with a contact cavity for accommodating metal contacts. One end of the contact cavity is open and the other end is closed. The outer wall of the metal contact sleeve 22 is The insulating shell 21 is fixedly connected, the rear part of the metal contact sleeve 22 passes through the insulating shell 21, the second end of the stem 25 is fixedly connected to the closed end of the contac...

Embodiment 2

[0028] This embodiment is further improved on the basis of the first embodiment, and further improves the security of the power supply interface. Such as Figure 4 As shown, in this embodiment, the metal contact head 13 is processed with a charging locking groove 14, the metal contact sleeve 22 also includes a charging locking device, and the metal contact sleeve 22 is processed with a locking hole corresponding to the charging locking groove 14, The locking hole runs through the side wall of the metal contact sleeve 22, and the insulating shell 21 is processed with a cavity for accommodating the live locking device. The live locking device can be a signal relay or an electromagnet.

[0029] The live locking device includes a mounting ring 31, a spring 32, a pin 33, a pin cap 34, a magnetic ring 35, a resistor R1, a resistor R2, a capacitor C and a diode D1. The mounting ring 31 is concentric with the locking hole and is fixedly installed on the metal contact sleeve 22 On th...

Abstract

The invention relates to the technical field of power supply equipment, in particular to a high-safety hot-plug low-voltage power supply interface. The interface is installed on a power supply equipment shell, and is characterized in that the interface comprises a hot plug and a socket; the hot plug comprises an insulating sleeve, a metal contact and an outgoing wire; the metal contact and the outgoing wire are both installed on the insulating sleeve; the socket comprises an insulating shell, a metal contact sleeve and a core column; a contact cavity for accommodating the metal contact is formed in the front part of the metal contact sleeve; the second end of the core column is fixedly connected with the closed end of the contact cavity, a core hole matched with the core column is machinedin the metal contact, the first end of the core column is flush with the open end of the contact cavity, the metal contact and the contact cavity are conical, the rear portion of the metal contact sleeve is connected with power supply voltage, and a wire outlet wire of the hot plug outputs electric energy. The invention has the substantial effects that the safety of the power supply interface isimproved through the core column; the hot-plug plug can be prevented from being pulled out by mistake in an electrified state through the electrified locking device, and the reliability of the power supply interface is improved.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a high-safety hot-swappable low-voltage power supply interface. Background technique [0002] In the practice of power distribution, it is often necessary to temporarily connect power supply equipment, such as power maintenance, temporary site power supply, or short-term expansion of the distribution station area. For example, in an area with a relatively developed tea-growing economy, there are a large number of users who plant tea trees. Every time the tea is fried, the electricity consumption of these users will increase significantly, and the high load will be concentrated between 7:00 and 12:00 in the evening. In the non-fried tea season, the user's load level returned to a lower level. The cost of upgrading the capacity of transformers in the Taiwan area is very high, and most of the capacity of the transformed transformers in the Taiwan area is wasted durin...
