Description

Communication line electric interfaces

Technical field

This utility model relates to fire communication technical field, particularly relates to a kind of order wire being applied to fire communication command system Road electric interfaces.

Background technology

Along with communication technology, the fast development of computer technology, fire communication command system plays in urban fire control works The most important effect, especially at fire accidents rescue site, needs formation trans-regional, many, many fire fighting trucks to work in coordination with Fighting, fire communication command system is most important.When China's fire fighting truck dispatches from the factory and designs at present, mostly do not reserve communication interface, On-the-spot at fire rescue, fire communication command system mainly uses communication, fire fighting truck communication to rely primarily on transmitter receiver, There is efficiency of transmission low, capacity of resisting disturbance is weak, transmits not smooth, the shortcomings such as definition is the highest, and signal is single.

Summary of the invention

For overcoming the deficiencies in the prior art, this utility model is that fire communication command system provides a kind of communication line and electrically connects Mouthful, it is achieved fire fighting truck and command car communication line are electrically efficient, connect accurately.

To achieve these goals, this utility model realizes by the following technical solutions:

A kind of communication line electric interfaces, including public access hands, female catcher, protection cap and waterproof back-up ring, described public access hands is by flat Side's guide pillar and public plug body are constituted, and female catcher is made up of female body, flat type hole guide pillar, shell fragment；Described protection cap is arranged on Public access hands, female catcher are outside；Described waterproof shield ring sleeve uses interference fits on hand at public access, and gear is in the boss front end of protection cap； During use, the flat type hole guide pillar that the flat guide pillar of public access hands inserts mother's catcher contacts realization electrical connection with shell fragment.

The internal one end of described protection cap is provided with and female catcher external screw thread fixing female thread in mating connection；The other end be provided with Waterproof back-up ring fixing boss in mating connection；Outside is provided with anti-skidding projection.Described public access hands, the plug body of female catcher are exhausted Edge portion uses ceramic material.Described female flat type hole guide pillar of catcher and the flat guide pillar of public access hands are multiple, arrangement mode For linear type, it is shaped as flat rectangular.

Compared with prior art, the beneficial effects of the utility model are:

1) fire fighting truck uses wire transmission mode with command car communication, and efficiency of transmission is high, capacity of resisting disturbance is strong, signal is polynary,

Image, word, video also can be received, it is simple to fire fighting truck adds fire communication net in addition to sound.

2) insulator uses ceramic material, and it is strong that pottery has high temperature resistant, corrosion-resistant, ageing resistance, and insulation effect is good

Characteristic, can effectively stop line signal to interfere, and clarity of signal is high, stable signal transmission.

3) the flat hole guide pillar of the flat guide pillar of public access hands and female catcher is shaped as deltiod, adds the compactness of contact,

It is not easy to loosen；Use linear type arrangement mode, compare circular arrangement mode and be directed at easily, connect quickly.

4) setting of protection cap and waterproof back-up ring not only can be with waterproof and dustproof, it is also possible to prevent catcher loose because of External Force Acting

Dynamic, depart from.

Detailed description of the invention

Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.

Embodiment: see Fig. 1, Fig. 2, a kind of communication line electric interfaces, mother take over 9, public access hands 10, protection cap 4, Waterproof back-up ring 14 forms, and female catcher 9 is made up of female body 1, flat type hole guide pillar 12, shell fragment 3, and public access hands 10 is by flat Side's guide pillar 13 and public plug body 5 are constituted.The internal one end of described protection cap 4 arranges boss 22, first protection cap 4 is enclosed within public affairs On catcher 10, after waterproof back-up ring 14 is enclosed within public plug body 5 position as shown in Figure 2, waterproof back-up ring 14 and public access hands 10 Use interference fits, gear before boss 22, flat guide pillar 13 (being connected with wire 7) is inserted flat type hole guide pillar 12 with Shell fragment 3 (connecting with wire 7) contacts formation path and realizes electrical connection.The internal other end of protection cap 4 arranges female thread 2, With the external screw thread 8 of female body 1 in mating connection fixing after, the axial displacement of public access hands 10 is i.e. limited, meanwhile The axial displacement of female catcher 9 is also limited, thus prevents public access hands 10 and female catcher 9 from loosening because of External Force Acting, departing from. Described protection cap 4 and waterproof back-up ring 14 are arranged on public access hands 10 and female catcher 9 is outside, play dust-proof, waterproof effect.

Described public plug body 1 and female body 5 insulated part use ceramic material to make.The flat of described public access hands 10 is led Post 13 totally 6 with the flat type hole guide pillar 12 of female catcher 9 totally 6 use straight line arrangement mode, be divided into two rows, often row 3, It is shaped as flat rectangular.Described waterproof back-up ring 14 uses water proofing property, elastic preferably the third quality of rubber materials to make.Described Protection cap 4 is outside is provided with anti-skidding projection, increases the frictional force of hand and protection cap 4, play anti-skidding when turning protection cap 4 Effect.

Seeing Fig. 3, female catcher 9 of this utility model a kind of communication line electric interfaces 17 is arranged on fire fighting truck 15, fire-fighting Be equipped with the communication apparatus such as information terminal processor 19, display screen 20, Mike 21, loudspeaker 16 on car 15, and with mother Catcher 9 is connected by wire 18.The flat guide pillar 13 of command car communication line electric interfaces 17 public access hands 10 is inserted and disappears The flat type hole guide pillar 12 of the female catcher 9 of anti-car 15 communication line electric interfaces 17 contacts with shell fragment 3, forms path, fire-fighting Communication i.e. set up by car 15 and command car.

The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model does not limit to In this, any those familiar with the art is in the technical scope that this utility model discloses, according to this utility model Technical scheme and utility model conceive equivalent or change in addition, all should contain protection domain of the present utility model it In.
