A button battery electrical connector

Abstract

The invention discloses a button battery electrical connector, which includes a protective cover and a connector main body; the protective cover includes an end cover, an annular retaining ring, a screw sleeve, an annular elastic washer, a cap, a conductive sealing pad, an insulating cover, and screws; The main body of the connector consists of a nut, a shell, an annular coil, an insulating base, an intermediate base, a conductive seal mounting rubber pad, a set screw, a positive contact, a negative contact, an insulator, and a fixed screw sleeve; the button of the present invention The battery connector has the features of preventing accidental disassembly of the protective cover, integrating battery replacement tools, electromagnetic shielding and sealing of the installation interface, which improves the electromagnetic shielding and interface sealing effect of the chassis, avoids power failure of the system caused by accidental removal of the protective cover, and is convenient battery replaced.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a button battery electrical connector. Background technique [0002] The invention patent with application number CN201510645514.7 discloses a battery connector, including a locking cover and a connector body. The locking platen in the locking cover and the locking screw sleeve are riveted and fixed together to form an integral body that cannot rotate relative to the axial direction. The rubber pad is bonded on the locking cover and cannot rotate relative to the axial direction. When the locking cover is put on the connector body, the rubber pad will rub against the battery negative terminal surface, which will easily wear out the rubber pad and produce excess, and will increase the locking and separating torque between the locking cover and the connector body , It is not convenient to replace the battery. The shell of the connector main body has no shielding structure, so ...

AI Technical Summary

Problems solved by technology

When the locking cover is put on the connector body, the rubber pad will rub against the battery negative terminal surface, which will easily wear the rubber pad to produce excess, and will increase the locking and separating torque between the locking cover and the connector body , not easy to replace the battery

The shell of the connector body has no shielding structure and cannot shield the battery, which will cause battery voltage fluctuations

The spring contact used is assembled from three parts, and the structure is too complicated

Since the battery connector is generally used to supply power to the system, an unexpected power failure will cause the system to be powered off, resulting in accidents

The battery connector does not have a redundant design to prevent accidental disassembly of the battery, and there is a risk that the battery will fall off due to the removal of the locking cover, resulting in an accidental power failure of the system

Therefore, the battery connector cannot be used in applications that require electromagnetic shielding and prevent accidental power failure risks, and has certain application limitations
