Abstract
The utility model discloses a waterproof connector, which consists of an external conductor, an internal conductor, an insulation support, a cable clip, a sealing ring and a rear threaded sleeve. Theutility model is characterized in that a groove is arranged on the insulation support and the sealing ring is inlaid in the groove. The sealing ring can effectively fill the gap between the insulationsupport and the external conductor and the gap between the insulation support and the internal conductor so as to prevent water and dust from entering the connector. The rear support structure is stable and the waterproof performance is excellent. The waterproof connector is suitable for various radio-frequency connectors which are connected with radio-frequency coaxial cables and can prevent water and moisture from entering the connector.
Description
Technical field
The utility model relates to a kind of radio frequency (RF) coaxial connector that connects radio frequency coaxial-cable, specifically a kind of waterproof, damp-proof radio frequency (RF) coaxial connector.
Background technology
In the prior art, the structure of connector is seen Fig. 1, and connector is made up of outer conductor 11, inner wire 12, insulation support 13, cable clip 14, sealing ring 15, rear thread sleeve 16.Because connector is in outdoor application, if connector is exposed in a humid environment, water may infiltrate connector inside along the slit between insulator and the inner and outer conductor, influence the normal use of connector.
The waterproof measure of taking at present is: after connector is installed, twine sealing with the cable junction with clay, adhesive tape at connector joint and connector, connector and external environment condition are completely cut off, reach waterproof, damp-proof purpose.There is following defective in this structure: 1) the price comparison height of clay, adhesive tape, cause the rising of engineering cost; 2) owing to be subjected to the restriction in project installation space, the winding of clay, adhesive tape is very inconvenient; 3) clay, adhesive tape belong to rubber, and the external environment condition of long term exposure is easily aging, thereby loses fire resistance characteristic.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this utility model provides a kind of simple installation, cost is low, reliability is high water-proof connector.This water-proof connector can prevent connector in use water infiltrate connector inside along the slit between insulator and the inner and outer conductor, influence the normal use of connector.
The purpose of this utility model is achieved through the following technical solutions:
A kind of water-proof connector comprises outer conductor, inner wire, insulation support, cable clip, sealing ring and rear thread sleeve, it is characterized in that: be provided with groove on insulation is supported, be inlaid with sealing ring in groove.
The utility model is equipped with groove on the contact-making surface of insulation support and outer conductor and inner wire, all be inlaid with sealing ring in groove.Sealing ring can effectively be filled up the gap between insulation support and outer conductor, the inner wire, anti-sealing, dust infiltration connector inside.
Described sealing ring is the O RunddichtringO.The material of described sealing ring is transformable, can be made by silicon rubber or the non-conductive nonmetallic materials of other rubber-like.
The utility model increases groove on insulation is supported, sealing ring is embedded in the groove, fills up the gap between insulation support and the inner and outer conductor, and anti-sealing, humidity enter connector inside, guarantee water resistance.The utility model is a kind of waterproof, damp-proof connector.
Compared with prior art, the utility model has the advantages that: 1) on-the-spot easy for installation, no longer be subjected to spatial limitation; 2), reduced the cost of engineering owing to inapplicable clay, adhesive tape; 3) stable performance of product, dependable performance.
The utility model is applicable in the various radio frequency (RF) coaxial connectors that connect radio frequency coaxial-cable, is used for anti-sealing, the moist connector inside of infiltrating.
Description of drawings
Fig. 1 is the structural representation of connector in the prior art;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Specify the utility model below in conjunction with accompanying drawing.
A kind of 7/16 interface water-proof connector described in the utility model is seen Fig. 2, and this water-proof connector comprises outer conductor 1, inner wire 2, insulation support 3, cable clip 6, sealing ring 7 and rear thread sleeve 8.On the contact-making surface of insulation support 3 and outer conductor 1 and inner wire 2, be equipped with groove 4, in groove 4, all be inlaid with sealing ring 5.Sealing ring 5 can effectively fill up insulation support 3 with outer conductor 1, inner wire 2 between the gap, anti-sealing, dust infiltration connector inside.
Sealing ring 5 is the O RunddichtringO.The material of sealing ring 5 is transformable, and in the present embodiment, sealing ring 5 is made by silicon rubber, and sealing ring 5 also can be made by the non-conductive nonmetallic materials of other rubber-like.
The utility model is filled up the gap of insulating between support and the inner and outer conductor by the sealing ring that is embedded in the groove, and anti-sealing, humidity enter connector inside, and water resistance is good.
