Description
Technical field
The utility model relates to cable joint technology, in particular for the water-tight joint of plastic cement cable, is specifically related to integrated cable waterproof and breathable joint.
Background technology
Cable joint claims again cable end or cable fixing head.After cable laying is good, in order to become a continuous circuit, it is as a whole that each section of line must connect, and these tie points are just called cable joint.The cable joint of cable line middle part is called transition joint, and the cable joint of circuit two ends is called terminals.Its Main Function is to make circuit unobstructed, makes the whole space at cable joint place keep sealing, and ensures the class of insulation of all components and parts in the space at cable joint place, and it is moved safely and reliably.If poor sealing, can leak and invade moisture, gently make decreasing insulating, heavy cause damaging all components and parts.If but complete hermetic words, in the casing of electrical connection position, can generate heat because of power, cause that inner when gases are heated, they expand and cannot discharge, internal pressure increases life-span and the safety that may affect electric elements, the stability of operation is bad, even likely causes the damage of components and parts in connecting portion casing; If pressure is excessive, air also may use picture to mould the sealing outside exhaust in position by other, and unexpected cooling rear air also can enter in casing by same position, and water and moisture can be followed and enter in casing simultaneously, thereby accelerate picture and mould the aging of sealing position, the safety that simultaneously threatens components and parts in casing.
Conventionally adopt independent perforate on the casing that is electrically connected position that waterproof and breathable plug is set, this waterproof and breathable plug adopts ventilative but fluid-tight ventilated membrane can be breathed freely airtight space, but simultaneously can waterproof and moisture immersion.But, because waterproof and breathable plug is independent setting, take up room larger, affect the aesthetic feeling of overall appearance, and also more time-consuming in the process of installing in processing simultaneously, also likely can have influence on the bulk strength of electric connecting part.Wherein ventilated membrane belong to prior art, air can see through but water cannot get through.
In prior art, in order to prevent the generation of above-mentioned situation, some products offer separately air-vent at top connection body side surface, realize respiratory function by this air-vent; But this structure need to additionally arrange film guard ring and by press seal circle, ventilated membrane is fixed on ventilative through hole, and it is more that this structure relates to part, assembling process need to carry out that screw thread is fixed or ultrasonic processing; If anabolic process is not closely sealed good, in use procedure, sealing ring and film guard ring easily occur looseningly, can cause the ventilated membrane problem that comes off.
Utility model content
For the problems referred to above, it is fast and convenient that the utility model aims to provide a kind of installation, and conserve space can effectively realize the integrated cable waterproof and breathable joint of respiratory function.
For realizing this technical purpose, scheme of the present utility model is: integrated cable waterproof and breathable joint, comprise top connection body, lower contact body, seal, box nut and nut, top connection body and lower contact body are combined into one by welding or rivet or being spirally connected, the described top connection body lower end box nut that is spirally connected, the lower contact body upper end nut that is spirally connected, seal is arranged between described top connection body and box nut, on interval between the upper end of the external thread structure of described top connection body and top connection body, be provided with air-vent, described top connection body inner side has been provided with annular gas permeable film on the position corresponding with air-vent, described lower contact body combines ventilated membrane fixing and locking on inner side corresponding to air-vent with top connection body by welding or rivet or being spirally connected.
As preferably, when hex nut structure that described top connection body is plastic cement, described ventilative through hole is four, is the symmetrical side that is opened in top connection body; When hex nut structure that described top connection body is metal, described ventilative through hole is six, is the symmetrical side that is opened in top connection body.
As preferably, between lower contact body and ventilated membrane, be provided with the each sealing ring of size.
As preferably, on described seal, also install plastic cement and claim cover.
As preferably, between described nut and lower contact body, be also equipped with joint sealing circle.
The beneficial effects of the utility model, on interval between the upper end of the external thread structure of top connection body and top connection body, be provided with air-vent, inner side is fixed with annular gas permeable film, make the joint not only can water-tight, and can be in time the Bas Discharged in seal or by the air intake of outside, so that the pressure in seal is consistent with local air pressure all the time, realize " respiratory function " of cable joint; The design adopts air-vent and the integrated design of top connection body, has reduced independently fixed structure of ventilated membrane, and more simple and fast is installed, and owing to being fixed on top connection body inner side, is also difficult for occurring the phenomenon that ventilated membrane comes off in use procedure.
