Abstract
A seal structure of a cable and a case body belongs to the cable seal connecting device technical field. The seal structure comprises a cable and an upper cover and a base which are in seal fit, and is characterized in that: both sides of the base are respectively connected with a pored column which is communicated with the cavity of the base; a cable passes through the pored column and extends into the base; and the head of the cable is in seal connection with the internal wall of the pored column through waterproof adhesive. The seal structure has a reasonable structure and excellent waterproof and sealing performance because the head of the cable is in seal connection with the internal wall of the pored column through waterproof adhesive. Moreover, the cable which extends into the base can be provided with a retainer ring and a seal ring so as to squeeze the waterproof adhesive into the gap between the pored column and the cable during pulling back the cable; and the retainer ring has stop function during pulling back the cable, which ensures simple operation. The seal structure ensures that an intact sealing ring is formed on a sealing surface; meanwhile, because the degree of protection of the case body reaches to IP65, the case body has excellent waterproof and sealing effect and can withstand the attack of sunlight, wind, rain, hail and heavy snow; therefore, the case body can be used outdoors for a long time along with high safety and reliability.
Description
Technical field
The utility model belongs to cable seal jockey technical field, is specially the hermetically-sealed construction of a kind of cable and box body.
Background technology
At present, electronic equipments such as the AC/DC transducer of decorative lamp or controller (as adopting AC/DC transducer or the controller of light-emitting diode) as the decorative lamp of light-emitting component, use out of doors because of long-term, stand solar radiation, expose to wind and rain and the attack of hail, heavy snow, the shell protection grade need reach IP44.For this reason, common way is that electronic equipment is placed in the plastic box body, the anti-drawing of bound rubber cable, anti-bending performance, and painting water-proof adhesive sealing on rubber sleeve reaches waterproof sealing effect with loam cake, box body together with the cable welding with the ultrasonic plastic welding machine again.But adopt above-mentioned this connection hermetically-sealed construction owing to all use the ultrasonic plastic welding machine to finish on cable and the sealing of whole box body, so be easy to cause the Plastic Welding face to bear very big stress, can slowly crack in the weakest place of fracture toughness, final box body can be intake because of explosion, cause being sealed in the circuit malfunction of electronic equipments such as interior AC/DC transducer of box body or controller, jeopardize people's life and property safety, have serious potential safety hazard.
Summary of the invention
At the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme of the hermetically-sealed construction that good cable of a kind of waterproof sealing and pedestal are provided, and can significantly improve the waterproof sealing of box body.
The hermetically-sealed construction of described a kind of cable and box body, comprise cable and the loam cake that is sealed and matched, pedestal, it is characterized in that the pedestal both sides connect the Kong Zhu that setting is communicated with its cavity respectively, cable passes Kong Zhu and stretches in the pedestal, and cable head and hole column wall are tightly connected by marine glue.
The hermetically-sealed construction of described a kind of cable and box body is characterized in that the cable inner end is equipped with back-up ring, sealing ring.
The hermetically-sealed construction of described a kind of cable and box body is characterized in that being equipped with in the pedestal positioning hole collumn, relative set alignment pin in the loam cake.
The hermetically-sealed construction of described a kind of cable and box body is characterized in that hole post and the socket of cable outer wall are provided with cable cover(ing).
The hermetically-sealed construction of described a kind of cable and box body is characterized in that being covered with the limit, lower edge, and the external annulus on limit, lower edge and the internal ring wall of pedestal are tightly connected by marine glue.
The hermetically-sealed construction of described a kind of cable and box body is characterized in that loam cake, pedestal seal welding.
The hermetically-sealed construction of described a kind of cable and box body is characterized in that described sealing ring is O RunddichtringO or cardboard circle.
The hermetically-sealed construction of above-mentioned a kind of cable and box body, rational in infrastructure, cable head and hole column wall are tightly connected by marine glue, and its waterproof sealing is good.Also can be equipped with back-up ring, sealing ring on the cable of base interior stretching into, marine glue is clamp-oned in the process that cable is pulled back in the slit between the Kong Zhuyu cable, back-up ring plays position-limiting action in cable is pulled back process, simple to operate.Adopt above-mentioned hermetically-sealed construction, sealing surface has formed complete closed-loop, and the degree of protection of its box body reaches IP65, waterproof sealing is effective, can stand solar radiation, expose to wind and rain and the attack of hail, heavy snow, can use out of doors for a long time, and safe in utilization, reliable.
