Description

Bent connector

Technical Field

The invention relates to the field of connectors, in particular to a bent connector.

Background

In the connector field, the main design points of connectors for transmitting digital signals are transmission loss, characteristic impedance, near-end crosstalk. In some special use cases, the connection direction and the incoming line direction of the connector must be bent in consideration of space limitation, namely, a common bent connector.

In digital circuits, one feature of the use of connectors is the need to make a plug, which multiple plugs means that the connector has no locking mechanism. In the existing bent connector, interference fit is generally carried out between a contact pin and an insertion hole, after the contact pin is fixed, the straight pin is inserted down, and then the straight pin is bent by a bending tool. In general, the pins are exposed, and for aesthetic reasons, a designer may design a baffle to block the pins.

However, the bent connector adopts an interference fit, and when the bent connector is connected, the contact pin is deformed under the action of external force due to the action of external force, and is mutually extruded with the external baffle, so that the contact pin is damaged, and the connection performance is reduced. Because the interference fit mode is adopted, the single contact pin cannot be replaced, and only the connector can be replaced integrally, so that the service life of the connector is reduced, and the maintenance of the connector is not facilitated.
