Problems solved by technology

In the outdoor antenna feeder system used for mobile communication base stations, the main method used to protect the connector from the corrosion of the aqueous solution of acidic and alkaline substances is to wrap the connector with mastic tape, but this method is not effective. The connector cannot be well protected, causing the connector to seep frequently during use and cause damage to the equipment

Embodiment 1

[0023] Embodiment one, such as figure 1 and figure 2 As shown, the connector includes a metal shell 3 and a screw sleeve 4; the protective shell 1 has a trumpet-shaped structure, and the opening faces the screw sleeve 4 and the opening is relatively large; the tail of the metal shell 3 is provided with a section of external thread, so The inner wall of the shell at the tail of the protective shell 1 is provided with an internal thread matching the above-mentioned external thread, and a rubber sealing ring 2 is also embedded in the end of the protective shell 1 . When the present invention is connected, one end of the cable 5 is put into the connector through the connecting hole 6 on the protective shell, and then the protective shell 1 is tightened by threaded connection, so that the sealing ring 2 is axially deformed and wrapped around the cable 5, so that the water cannot flow with it. Cable 5 enters the connector tail. The protective casing 1 described in this example i...

Embodiment 2

[0027] Embodiment two, such as Figure 5 , Figure 6 As shown: on the basis of Embodiment 1, an annular groove 71 is formed on the open end surface of the front housing 7 , and protrusions 72 are formed on the top and bottom of the front end of the groove 71 .

[0028] When the front shell 7 is connected with the protective shell 1, the open end of the protective shell 1 is inserted into the annular groove 71 of the open end of the front shell and tightly connected with the protrusion 72 in the groove;

[0029] In order to better improve the waterproof performance, the rear end of the front housing 7 is in contact with the flange surface of the mating connector 9 .

[0030] The design principle of the present invention is to use the opening end of the protective shell to insert into the groove of the front case, and its end face is against the end face of the groove of the front case, and produces axial deformation; the two protrusions in the groove and The inner and outer d...

Abstract

The invention relates to the technical field of cable connectors, in particular to a cable connecting system. The cable connecting system comprises a connector, a mating connector, a protective shell and a front shell, wherein the protective shell is connectedly sleeved on the connector, a sealing ring is embedded into a joint of the tail end of the protective shell and the connector, the front shell is connectedly sleeved on the mating connector, and an opening of the front shell and an opening of the protective shell are opposite to each other and are hermetically and fittingly connected with each other. The cable connecting system well achieves that the connector is protected from being corroded by aqueous solution of acid and alkaline substances in an outdoor antenna feed system, is simple in structure, low in price and high in practical value and can be widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of cable connectors, in particular to a waterproof cable connection system. Background technique [0002] In mobile communication base stations or indoor coverage systems, it is indispensable to use connectors to transmit high-frequency signals and power. One-piece crimp connectors are mainly divided into two categories: one is one-piece crimp connectors with ordinary cables; the other is one-piece crimp connectors with ultra-flexible RF coaxial cables. In the outdoor antenna feeder system used for mobile communication base stations, the main method used to protect the connector from the corrosion of the aqueous solution of acidic and alkaline substances is to wrap the connector with mastic tape, but this method is not effective. The connector cannot be well protected, resulting in frequent water seepage of the connector during use and damage to the equipment. Contents of the invention [0003] In order ...
