Description

Anti-loosening connector

Technical Field

The utility model relates to the technical field of connectors, in particular to an anti-loosening connector.

Background

Connectors, also known as connectors, plugs and sockets, generally refer to electrical connectors, i.e. devices that connect two active devices to transmit electrical current or signals. The function is important, namely, a bridge for communication is erected between the blocked or isolated circuits in the circuit, so that current flows, and the circuit realizes the preset function.

Connectors are indispensable components in electronic devices, and one or more connectors are always found along a path through which current flows, and the form and structure of the connectors are variously changed, and various types of connectors are provided according to the application object, frequency, power, application environment, and the like. For example, connectors for lighting on a court and connectors for a hard disk drive, and connectors for lighting a rocket are quite different. Whatever the connector, however, a smooth continuous and reliable flow of current is ensured. Therefore, the problem of enhancing the anti-loosening performance of the connector plug (plastic shell connector) and the socket (needle seat) is primarily solved.

In practical production and application, the connector often has different forms of failures, such as broken needle cores of the needle seats, few needles, the plastic shell of the needle seats, loose of the needle seats and the wire connector, and the hidden trouble of failure modes of the plastic shell of the needle seats, loose of the needle seats and the wire connector in the faults is larger, the contact resistance of the needle seats and the wire connector is increased due to poor contact, and the phenomena of ignition and burning are seriously likely to occur. After the assembly of the wire connector and the needle seat is completed, the probability of stress in the actual production turnover process is larger because the connector wire is longer, and if the retention force between the plastic shell and the needle core is smaller, the problem of loose connection can occur. Accordingly, one of ordinary skill in the art now proposes a loose-proof connector.
