Abstract
The utility model relates to a waterproof electric plugging connector used for an electric heating floor. The waterproof electric plugging connector comprises a male connecting plug and a female connecting plug. The male connecting plug and the female connecting plug are provided with a pair of a negative electrode and a positive electrode which are suitable for plugging connection; the negative electrode and the positive electrode are injected in the shell; a male connecting plug shell is an injection molding body with a plug hole at the front end thereof; a female connecting plug shell is an injection molding body with a convex-shaped plugging part at the front end thereof; the plug hole of the male connecting plug shell matches with the convex-shaped plugging part of the female connecting plug shell and are in a plugging connection structure; and the surface of the plugging part is provided with two convex loops. The outer diameters of the convex loops are a little larger than the inner diameter of the plug hole of the male connecting plug shell. The waterproof electric plugging connector has the beneficial effects that the plug hole wall of the male connecting plug is a flexible body; the female connecting plug is provided with the convex loops, so that the connection of the male connecting plug and the female connecting plug can guarantee that the male connecting plug and the female connecting plug are firmly connected and are not easy to fall off; and the waterproof electric plugging connector has seal waterproof properties.
Description
Technical field
The utility model relates to a kind of for the water-proof type electrical connectors on electric heating floor.
Background technology
The electric heating floor that people use is comprised of the splicing of N module unit electric heating floor, and the electric wire between each unit electric heating floor need interconnect, and electric wire tie point is completed by electrical connectors.At present conventional electrical connectors in use exists following point: 1, without waterproof sealing structure, design, on floor, can not avoid water may be penetrated in floor, in this case, water may enter in electrode by the gap at male and female connection-peg interface place, if now energising, can produce serious electric leakage; 2, the connection of the electrical connectors in electric wire is insecure, and after electric wire tension, male and female connection-peg is easily thrown off, and causes circuit breaker, and the circuit on floor is underground, once there is electric leakage, cannot repair in time, usually can only damage floor and just can address this problem.
Summary of the invention
The object of the invention is to overcome the problems referred to above, provide a kind of simple in structure, simple installation, water proofing property better and tension difficult drop-off electrical connectors.
The technical solution adopted in the utility model is: a kind of for the water-proof type electrical connectors on electric heating floor, comprise male plug joint and female plug joint, it is characterized in that: male plug joint with in female plug joint, be provided with a pair of yin, yang electrode that is suitable for pegging graft and is connected, yin, yang electrode is injection-moulded in housing, and male plug termination casing is the injection molding body that a front end is provided with spliced eye; Female plug joint housing is the injection molding body that a front end is provided with " protruding " shape interpolating unit; " protruding " shape interpolating unit of the spliced eye of male plug termination casing and female plug joint housing matches, and is connected structure.
Further, for preventing male plug joint and the rear difficult drop-off of female plug joint grafting and having water-tight performance, described interpolating unit appearance is provided with twice bulge loop circle, and this bulge loop circle outside dimension is slightly larger than male plug termination casing spliced eye internal diameter size.
Further, for the bulge loop circle in female plug joint housing can conveniently be inserted in the spliced eye of male plug joint, and after guaranteeing to peg graft, both can firmly connect difficult drop-off, and the grafting hole wall of described male plug joint is flexible body, has elasticity, and material is nylon.
Further, for meeting the multiple interfaces of circuit line between each unit electric heating floor, described male and female connection-peg can be designed to tandem interface, also can be designed to parallel interface.
The beneficial effects of the utility model are: because the grafting hole wall of male plug joint is flexible body, on female plug joint, with bulge loop circle, such male and female connection-peg is plugged in together, can guarantee both peg graft after firmly connection, difficult drop-off and there is water-tight performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is electric heating floor circuit connection diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, Fig. 2, embodiment of the present utility model is described in further detail:
A kind of for the water-proof type electrical connectors on electric heating floor, comprise male plug joint 1 and female plug joint 2, it is characterized in that: male plug joint 1 with in female plug joint 2, be provided with a pair of anode 11 and negative electrode 21 that is suitable for pegging graft and is connected, anode and cathode is injection-moulded in respectively in housing 12 and 22, and male plug termination casing 12 is injection molding bodies that a front end is provided with spliced eye 121; Female plug joint housing 22 is injection molding bodies that a front end contains stair-stepping " protruding " shape interpolating unit 221; The spliced eye 121 of male plug termination casing 12 matches with " protruding " shape interpolating unit 221 of female plug joint housing 22, is connected structure.
Further, for preventing male plug joint 1 with the female plug joint rear difficult drop-off of 2 grafting and thering is water-tight performance, described female plug joint housing 22 appearances are provided with twice bulge loop circle 222, and the outside dimension of this bulge loop circle 222 is slightly larger than the internal diameter size of male plug termination casing spliced eye 121.
Further, for the bulge loop circle 222 of female plug joint 2 can conveniently be inserted in the spliced eye 121 of male plug joint 1, and after guaranteeing to peg graft, both can firmly connect difficult drop-off, and the wall of the spliced eye 121 of described male plug joint 1 is flexible body, has elasticity, and material is nylon.
Further, for meeting the multiple interfaces of circuit line between each unit electric heating floor 3, described male and female connection-peg (1,2) can be designed to tandem interface 4, also can be designed to parallel interface 5.
