Description

Antenna feeder system connector protection device

technical field

The invention belongs to the field of antenna feeder system connectors, in particular to a protection device for an antenna feeder system connector.

Background technique

In the communication industry, in order to ensure the firm connection of cables, connectors are required. The fixed part of the existing antenna feeder system connector usually adopts a blue-shaped cable clamp structure. This structure has limited clamping force and small friction with the cable surface. When working outdoors, it will be affected by external forces such as wind. , so that the cable and the connector fall off, affecting its normal working performance.

In order to improve the protective performance of the connector, there are also plans to design a protective box outside the connector, such as the Chinese patent announcement number: CN201450094U, which discloses a 3G antenna feeder system connector protective box, which is composed of an upper box body and a lower box body , fixed lock and gel, there is a semi-arc connector placement groove at one end of the upper box body and the lower box body, and a hinge is provided between the upper box body and the lower box body. There is a fixed lock on the side, and the fixed gel is injected into the protective box. However, since the upper and lower boxes are fixed with fixed gel pressure injection, when disassembling, the protective box can only be removed by violent removal. The protective box will inevitably be damaged and cannot be used repeatedly. Also more inconvenient.

The internal thread of the external connection part can cooperate with the external thread on the internal connection part, so that the A-end cap body is threadedly connected with the A-end sealing plug body, and the B-end cap body is threadedly connected with the B-end sealing plug body. In addition, the A-end sealing plug body and the B-end sealing plug body are also connected through threads. In order to ensure the tightness between the A-end sealing plug body and the B-end sealing plug body, a sealing ring is set between the A-end sealing plug body and the B-end sealing plug body. When the A-end sealing plug body and the B-end sealing plug body are tightened Make sure both are sealed. The outer end of the inner connecting part is provided with several clamping petals 4 arranged in the circumferential direction, and gaps are provided between adjacent clamping petals. The outer periphery of the cap body at the A end and the outer periphery of the cap body at the B end are provided with a plurality of protrusions arranged at intervals, and a plurality of anti-slip stripes are provided between adjacent protrusions.

Since the connection structure between the A-end cap body and the A-end sealing plug body is the same as the connection method between the B-end cap body and the B-end sealing plug body, the connection between the B-end cap body and the B-end sealing plug body is taken as an example. As shown in Fig. 2, an annular groove is provided inside the inner connecting part, a sealing body 5 is arranged in the annular groove, and a cavity 5a is arranged in the sealing body, both the sealing body and the cavity are annular, and the cavity is coaxially arranged in the sealing body. The inner connecting part is provided with a positioning part 16 extending to the bottom of the sealing body, and a chute 16a is arranged inside the locating part, and the chute and the inner connecting part are axially arranged in parallel, and a sliding block 18 is arranged in the chute, and the sliding block can move along the The chute moves back and forth relative to the sealing body, the end of the slider close to the sealing body is provided with a piston rod 19, the end of the sealing body is provided with a through hole communicating with the cavity, the through hole is sealed with the piston rod, and one end of the piston rod passes through the through hole Entering the cavity, the other end of the piston rod is fixedly connected with the slider. When the slider approaches the sealing body, it drives the piston rod to pressurize and expand the cavity of the sealing body, and when the slider moves away from the sealing body, it drives the piston rod to leave or extend into the cavity.
