Communication connector capable of detecting air tightness
Technical Field
The invention relates to the technical field of communication detection, in particular to a communication connector capable of carrying out airtightness detection.
Background
The connector is an indispensable component in an electronic device, and the connector form and structure are varied, and there are various different forms of connectors depending on the application object, frequency, power, application environment, and the like.
A telecommunications connector is disclosed in, for example, patent No. CN109921227A, which includes a fixed base, a conductive terminal mounted in the fixed base, a housing surrounding the fixed base, and a collar mounted on the housing and capable of floating up and down. When the communication connector is butted with a butting connector, the butting connector presses down the lantern ring and the conductive terminal, and the lantern ring can move downwards together with the conductive terminal through fracture design, so that the conductive terminal is protected. Meanwhile, the conductive terminal is compressed, so that a certain contact force can be formed with the butt joint terminal of the butt joint connector. The conductive terminals can be reliably contacted with the butt terminals through the structural design of the two aspects, so that the stability of signal transmission is improved.
For another example, patent No. CN104638437B discloses a communication connector including a transmission frame module, a housing body, a connection end housing, and a latch frame. The transmission frame module is provided with a plurality of pins which can form a connecting terminal part and a mounting terminal part. The cover sleeve body is provided with a top plate and two side plates extending from the top plate and used for covering the transmission frame module, one end of the cover sleeve body is a connecting end notch containing a first embedded part, and the side plates define a plate end notch in the direction of the mounting terminal part, so that the connecting terminal part and the mounting terminal part respectively extend out from the connecting end notch and the plate end notch. One end of the connecting end cover sleeve is provided with a second scarf joint part which is used for scarf joint with the first scarf joint part, and the connecting terminal part extends and passes through a cavity in the connecting end cover sleeve to be formed at the other end of the connecting end cover sleeve. The bolt frame piece can be simultaneously abutted and combined with the cover sleeve body and the connecting end cover sleeve to fix the connection between the connecting end cover sleeve and the cover sleeve body, thereby achieving the technical effect of enhancing the strength of the assembly structure.
However, the currently used connector is mainly of a splicing type combined structure, generally does not have an air tightness detection function, cannot automatically trigger and start a detection function in a plugging process, generally has a connection function, and does not have an auxiliary function of quick assembly and quick unlocking, so that the existing requirement is not met, and the communication connector capable of carrying out air tightness detection is provided.
