Dual overheating protection safety type connector

Abstract

The invention relates to the technical field of connectors, and discloses a dual overheating protection safety type connector which comprises a rack, a mounting frame is fixedly connected to the bottom of the rack, a power line is fixedly connected to the end, away from the rack, of the mounting frame, and a connecting mechanism is movably connected to the interior of the rack. A trigger mechanism is movably connected to the interior of the side wall, close to the mounting frame, of the rack, a protective resistor is placed in the mounting frame, a connecting mechanism comprises a metal sheet, a sliding groove is formed in the side face, close to the metal sheet, of the rack, a sliding frame is slidably connected to the interior of the sliding groove, and an electromagnetic rod and a magnetic block repel each other. A telescopic rod on the upper side of the sliding frame stretches, a metal contact on the lower side of the sliding frame makes contact with a contact on the lower side of the sliding frame, and a protective resistor on the lower side of the mounting frame is powered on, so that the effects that the protective resistor can be replaced in time when one protective resistor is fused, dual protection is achieved, and equipment damage caused by sudden power failure is avoided are achieved.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a double overheat protection safety connector. Background technique [0002] When the connector can connect the electrical appliance with the external power supply, it supplies power to the inside of the electrical appliance. In order to avoid damage to the electrical appliance caused by the voltage change of the external power supply, a protective resistor is generally installed inside the connector, and the electrical appliance can be protected by a fuse resistor when it is overloaded. Internal electronics are protected. [0003] However, there is only one internal protective resistor in the current connector, and it cannot be automatically replaced when one protective resistor is blown, causing the electrical appliance to be directly powered off, causing greater damage to the electrical components inside the electrical appliance, and at the same time, it cannot be connected...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a dual overheating protection safety connector, which is equipped with automatic replacement of resistors, avoids direct power failure of electrical appliances, and at the same time warns the outside world when all internal protection resistors are blown, reducing inspection steps and improving work efficiency and other advantages, it solves the problem of direct power failure of electrical appliances, causing greater damage to electrical components inside the appliance, and at the same time, it cannot warn the outside world when the internal protection resistor of the connector is blown, which increases the steps for the staff to check the circuit and reduces the workload. efficiency problem
