Abstract
The invention relates to an LVDS connector. The LVDS connector comprises an insulation body, a plurality of conductive terminals accommodated in the insulation body and a metal housing wrapping the insulation body. The insulation body comprises a base portion and a lingual portion protruding forwards from the base portion. The conductive terminals comprise a plurality of difference signal terminals and a plurality of grounding terminals, each conductive terminal comprises a contact portion arranged on the lingual portion, and the metal housing is provided with an elastic arm abutting against the grounding terminals in a punching mode to enable a grounding loop to be formed between the metal housing and the grounding terminals, such that the impedance of the LVDS connector is reduced, and the high-frequency transmission quality is improved.
Description
Technical field
The present invention relates to a kind of LVDS cable-assemblies, more particularly to a kind of LVDS connectors with metal shell.
Background technology
Low-voltage differential signal（Low Voltage Differentical Signal, abbreviation LVDS）Interface standard, has
The high anti-interference ability with high-speed transfer, extensively using the transmission signal of liquid crystal display.At present, it is many using soft on the market
Flat wire, LVDS connectors composition LVDS connectors, with low cost and easy to manufacture characteristic, increasingly by each manufacturer with
The welcome of consumer.However, the good high frequency performance to ensure LVDS connectors, the metal shell of LVDS connectors generally with it is flat
The screen layer conducting of horizontal line, reaches earth-return circuit, however, the impedance of LVDS connectors is still higher, have impact on the product of high-frequency transmission
Matter.
Thus, it is necessary to design a kind of new LVDS connectors to solve above-mentioned technical problem.
The content of the invention
Object of the present invention is to provide a kind of have the low-impedance LVDS connectors of drop.
To realize object defined above, the present invention is adopted the following technical scheme that：A kind of LVDS connectors, it include insulating body,
The some conducting terminals being contained in insulating body and the metal shell of coated insulation body, the insulating body include base portion and
From the tongue that base portion is protruded out forward, the conducting terminal includes some difference signal terminals and some ground terminals, each conduction
Terminal includes the contact site being arranged on tongue, and the metal shell punching is provided with the elastic arm being connected on ground terminal.
LVDS style metal shell of connector of the present invention punching is provided with the elastic arm being connected on ground terminal so that metal shell with
Ground terminal forms earth-return circuit, advantageously reduces the impedance of LVDS connectors, improves the quality of high-frequency transmission.
