Description

Quick attaching water-proof connector

Technical field

The utility model plant equipment, the transmission technique field of communication, be energized field and new equipment signal, refers to a kind of attaching water-proof connector fast especially.

Background technology

Along with the development of modern science and technology art, requirement is set up to the cable in the systems such as communication, radar, electronic countermeasures, unlimited conductance boat more and more higher, especially in electrical property.And the raising of the standard along with cable assembly required by user, makes radio frequency connector design in every respect more rigorous.We have carried out breakthrough reform with regard to this direction of air-tightness.

At present, N series connector is a kind of middle low power connector with threaded connection according to U.S. army mark MIL-C-39012 development and production, is widely used in wireless device and is connected radio frequency cable use in instrument.This is a maturation, conventional connector, and it has, and shock resistance is strong, reliability is high, machinery and the feature of excellent electrical properties.When connector uses out of doors, usually have watertight requirement, in existing connector industry, conventional connecting cable watertight product generally has three kinds of structures, (see Fig. 1, Fig. 2, Fig. 3).Product shown in Fig. 1, complex structure, part is many, and cost is higher, and various parts machining tolerance can affect product watertightness performance, assembles loaded down with trivial details, inefficiency simultaneously.Product shown in Fig. 2, this structure be screw thread revolve with time by sealed ring deformation extruding screen to realize watertightness performance.But the compression ratio of sealing ring is difficult to control, easily causes sealing ring to extrude tension, especially have a strong impact on when high band and affect standing wave performance; Or extruding too pine, do not reach waterproof requirement.Product shown in Fig. 3 is cable welding structure, and this structure necessarily requires the cable insulation selected to be necessary for polytetrafluoroethylene or the cable of leading as copper pipe outward.Low loss cable conventional in communication can not adopt this welding manner.This structural disadvantages is that efficiency is low simultaneously, cannot reprocess, greatly increase production cost after welding.

Utility model content

The purpose of this utility model is to provide a kind of attaching water-proof connector fast, and this component can solve the problem, and simplifies the structure, and greatly reduces part and cost of labor, simultaneously good sealing effect.

To achieve these goals, the utility model have employed following technical scheme: attaching water-proof connector fast, comprise shell, coordinate the wire clamp of clamping cables screen with shell, outer annular groove is had outside described shell, inside described wire clamp, have interior cannelure, in described interior cannelure and outer annular groove, be equipped with sealing ring.

The beneficial effects of the utility model are: after adopting said structure, reduce product parts, simplified structure, only realize the watertightness performance of product with 2 sealing rings, fast install, and greatly reduce part and cost of labor.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment technical scheme, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only that the utility model is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below the accompanying drawing used required in p-embodiment or description of the prior art is briefly described, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is internal water-proofing structure schematic diagram in conventional art;

Fig. 3 welds waterproof construction schematic diagram in conventional art;

Fig. 4 is structural representation of the present utility model.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Quick attaching water-proof connector as shown in Figure 4, comprise shell (1), coordinate the wire clamp (2) of clamping cables screen with shell (1), outer annular groove is had outside described shell (1), have interior cannelure in described wire clamp (2) inner side, in described interior cannelure and outer annular groove, be equipped with sealing ring (3).

Wire clamp (2) and shell (1) are two independent individuals, after connecting cable, cable shield enters gap between shell (1) and wire clamp (2), by frock, wire clamp (2) cylindrical is pressed into six sides with clamping cables again, now sealing ring (3) also crimp, product meets watertight requirement.This product simplification structure, reduces product parts, only realizes the watertightness performance of product with 2 sealing rings (3), fast installs, and greatly reduces part and cost of labor.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.

Claims (1)

1. quick attaching water-proof connector, it is characterized in that, comprise shell (1), coordinate the wire clamp (2) of clamping cables screen with shell (1), outer annular groove is had outside described shell (1), have interior cannelure in described wire clamp (2) inner side, in described interior cannelure and outer annular groove, be equipped with sealing ring (3).
