Description

a curved connector

technical field

The present invention relates to a curved connector.

Background technique

At present, the connectors applied to outdoor communication equipment can be divided into straight connectors, hose transfer connectors and curved connectors according to the structure of the cable protection part.

The structure of the straight connector 102 connected to the outdoor communication equipment 101 is shown in FIG. 1. When wiring the cable 103, the cable 103 is first bent at a certain angle at the end of the straight connector 102, and then the wiring is performed. Due to the limitation of the bending radius of the cable 103 itself, the wiring space H1 required by the straight connector 102 is relatively large, which is not suitable for high _- density wiring requirements.

The structure of the hose adapter connector 202 connected to the outdoor communication equipment 201 is shown in FIG. 2 . When the cable 203 is wired, the cable 203 and the hose of the hose adapter connector 202 are first bent at a certain angle, After wiring, due to the limitation of the bending radius of the cable 203 and the hose, the wiring space _H2 required by the hose adapter 202 is large, which is not suitable for high-density wiring requirements.

The structure of the curved connector 302 connected to the outdoor communication device 301 is shown in FIG. ₃ , when the cable 303 is wired, the cable 303 does not need to be bent, and the wiring space H3 required by the curved connector 302 is small, which is suitable for High density wiring requirements.

Due to the curved arrangement of the plug housing of the angled connector, it is difficult to install the ferrule component. In order to solve the above problems, the Chinese invention patent application with the application publication number CN106384906A discloses a curved connector, which includes a connector housing, and the connector housing includes a plug-in terminal housing and a terminal housing. The terminal housing It is connected with the plug-in terminal housing at a set angle, the terminal housing is provided with a cable sealing structure, the rear end of the connector housing is provided with an opening, and a tail cover adapted to its shape is installed on the opening. The tail cover includes an upper part whose axis coincides with the axis of the plug-in terminal housing and a lower part whose axis is parallel to the axis of the terminal housing and whose cross section is a sector-shaped ring; the abutment surface between the tail cover and the opening is provided with gasket.

In order to ensure the sealing performance of the above-mentioned curved connector, it is not only necessary to set a sealing gasket between the butt surface of the tail cover and the opening, but also to set a cable sealing structure on the terminal shell, which not only improves the sealing performance of the curved connector. It is not easy to guarantee, and the assembly of the bent connector is complicated, which affects the production efficiency.
