Description

Wall-penetrating type watertightness cable connector

Technical field

The present invention relates to technical field of electric connectors.

Background technology

In all kinds of electronic systems, electric connector is electrically connected and the signal transmission between device and device, assembly and assembly, system and system, is to consist of the necessary base components of holonomic system.At present at deep water and marine field, electric connector is used less, the relative vacancy of technology in this respect, and the watertightness cable connector not only requires to have the waterproof sealing function under certain depth condition, more require under certain hydraulic condition keeping system working properly.

The generic connectivity device is not because Butt Section and tail end are all taked seal approach, so can't use under water.And Sealed casing pipe or sealing gasket are adopted in present existing water-proof connector butt end, and tail end adopts the form of sealing shroud to make connector reach integral sealing effect, can guarantee to use normally under certain depth condition, can't use but darker condition is next under water.

Summary of the invention

The object of the present invention is to provide a kind of wall-penetrating type watertightness cable connector, make the electric connector can installation through walls and darker condition lower connector is inner for sealing state and bear certain hydraulic pressure under water, keep the working signal transmission normal, but and socket install after two ends banjo all.

For achieving the above object, the present invention adopts following scheme:

Described wall-penetrating type watertightness cable connector, formed by plug and socket, wherein plug comprises swivel nut, plug sealing gasket, plug body, jack, Plug base component, jack places the Plug base component plug body of packing into, swivel nut is sleeved on the plug body butt end, and the plug sealing gasket is installed on corresponding end-faces between swivel nut and the plug body butt end; Described socket comprises jack housing, socket seal pad, two socket base components, contact pin, the contact pin two ends suits socket base component jack housing of packing into, between jack housing and the two socket base component end faces, one socket seal pad is installed respectively, the cable of described plug body tail end is the plastic packaging cable, embedding fluid sealant between the described two socket base components.

Described plug body butt end outer ring surface is provided with annular groove, and plug O RunddichtringO is housed in this annular groove; The end face of described jack housing outer ring surface and middle bench is respectively equipped with an annular groove, and socket O RunddichtringO a, socket O RunddichtringO b are housed respectively in the described annular groove.

After adopting the said structure scheme, that watertightness cable connector through walls of the present invention has is simple in structure, effect is good, characteristics stable and reliable for performance are applicable to the application scenario that electric connector needs through walls and waterproof sealing requirement, can satisfy the user demand of novel device.

Embodiment

Below in conjunction with the accompanying drawing example watertightness cable connector through walls of the present invention is described in further detail:

Described wall-penetrating type watertightness cable connector, formed by plug and socket, wherein plug comprises swivel nut 1, plug sealing gasket 3, plug body 4, jack 5, Plug base component 6, jack 5 places Plug base component 6 plug body 4 of packing into, swivel nut 1 is sleeved on the plug body butt end, and plug sealing gasket 3 is installed on corresponding end-faces between swivel nut 1 and plug body 4 butt ends; Described socket comprises jack housing 8, socket seal pad 9, two socket base components 12, contact pin 14, contact pin 14 two ends suits socket base component 12 jack housing 8 of packing into, between jack housing 8 and two socket base components, 12 end faces, one socket seal pad 9 is installed respectively, the cable of described plug body 4 tail ends is plastic packaging cable 7, embedding fluid sealant 13 between the described two socket base components 12, embedding fluid sealant 13 is the fluid sealant of one or both different densities between the described two socket base components 12.

Described plug body 4 butt end outer ring surfaces are provided with annular groove, and plug O RunddichtringO 2 is housed in this annular groove; The end face of described jack housing 8 outer ring surfaces and middle bench is respectively equipped with an annular groove, and socket O RunddichtringO a10, socket O RunddichtringO b11 are housed respectively in the described annular groove.

In the such scheme, the plug tail end adopts plastic packaging cable 7, manufacturing process is to pass through the injection mo(u)lding of mould HTHP after carrying out the plug cable, described plastic packaging cable 7 bears after the extraneous normal pressure tightr under water, guarantee that its sealing is reliable, the plug butt end adopts the structure of O shape circle 2 and sealing gasket 3 can guarantee that working signal is normal transmission on contact at certain hydraulic condition lower connector inner sealing.

12 of the two pedestal components of socket take the mode of embedding fluid sealant 13 can reach the function that two ends seal each other, fluid sealant 13 can guarantee in the situation of socket one end inefficacy, hydraulic pressure can not be delivered to the other end by fluid sealant 13, thereby improved the fail safe of plug and socket, the socket butt end adopts the structure of sealing gasket 9 to guarantee under certain hydraulic condition, working signal is normal transmission on contact, O-ring seals 10 and O-ring seals 11 is set in the mounting panel position simultaneously can guarantees to have the water-stop function after socket is installed.

The present invention's watertightness cable connector body through walls is installed by mounting panel 15, locking nut 16.As shown in Figure 3, O RunddichtringO 10 (end face seal) and O RunddichtringO 11 (radial seal) were compressed filling groove after socket was installed, stop its fluid-encapsulated flowing, like this with after the arbitrary end docking of plug and socket, anti-sealing is penetrated into the other end from installation panel when guaranteeing its sealing, guarantees that the facilities such as the components and parts of connector tail end and cable can not be subject to the impact of external water pressure.

The socket two ends of watertightness cable connector through walls of the present invention all can be docked with plug, after the plug and socket docking, plug body 4 compression socket seal pads 9, plug O RunddichtringO 2 is subject to jack housing 8 compressions and fills annular groove, simultaneously jack housing 8 front ends compression plug sealing gasket 3, the flowing of fluid that has stoped its sealing, and the elastic compensating of rubber manufacturing and fit tolerance, the elastic memory of its material internal is to keep the important means of sealing.
