Abstract
The utility model relates to a waterproof plug and socket comprising a socket housing, a plug housing, a convex ring connected on the outer surface of the socket housing with a sealed state, and a sealing ring. When pins are inserted into the insertion holes, the sealing ring is subjected to radial pressing, such that the convex ring and the socket housing are connected in the sealed state. A plurality of insertions holes are arranged in the socket housing. A plurality of pins are arranged on the socket housing. The insertion holes are positioned in a space formed by the convex ring. According to the waterproof plug socket provided by the utility model, the sealing effect of the plug and socket and the connection effect of the plug and socket are independent of each other. During an existing waterproof work of a connection place of a plug and a socket, with the reducing of the connection force of the plug and the socket, a phenomenon of poor sealing is caused; and with the reaction force of the sealing ring to the plug socket, the connection force of the plug and socket is reduced, and a problem of connection loosening between the plug and socket is accelerated. With the utility model, the problems are solved.
Description
Technical field
The utility model relates to plugs and sockets, relates in particular to a kind of waterproof plug socket.
Background technology
Generally, plugs and sockets can only use in anhydrous environment.But in actual operating position, plugs and sockets touches water sometimes, as places such as engineering, outdoor, toilet, kitchens.In order to guarantee the Electrical Safety in these environment, just need have the plugs and sockets of water-proof function.
Be 2011201601553 in China Patent No., Granted publication day be November 16 in 2011 day, be called in the patent document of " a kind of waterproof plug " and disclose a kind of plug with water-proof function, plug in this patent document comprises plug casing, be arranged at the latch of plug casing and be connected electrically in the electric wire of latch the inner, the face of plugging together at plug casing is provided with sealing ring, and latch is positioned at the space that sealing ring surrounds.When plug is inserted on the socket, sealing ring with the plugs and sockets face of plugging together be sealed connected together, anti-sealing enters from the plugs and sockets junction.More than waterproof is carried out in the plugs and sockets junction mode have the following disadvantages: owing to rely on sleeve in the socket chucking power (connecting power hereinafter referred to as plugs and sockets) of the latch in the plug to be kept the strain of sealing ring, be easy to generate the poor sealing phenomenon Gu connect the reduction of power along with plugs and sockets, sealing ring can reduce plugs and sockets connection power and accelerate to produce between the plugs and sockets the loosening phenomenon of connection the reaction force of plugs and sockets.
The utility model content
The utility model provides a kind of sealing function of plugs and sockets with the connection effect of plugs and sockets waterproof plug socket independent of each other, has solved existingly the existing reduction that connects power along with plugs and sockets in the process of waterproof is carried out in the plugs and sockets junction to be easy to generate poor sealing phenomenon, sealing ring and can to reduce plugs and sockets to the reaction force of plugs and sockets and connect power and accelerate to produce between the plugs and sockets problem that connects loosening phenomenon.
Above technical problem solves by following technical proposal: a kind of waterproof plug socket, the sealing ring that is subjected to radial compression when comprising Socket casing, plug casing, be sealedly attached to the bulge loop on the described Socket casing outer surface and be used in described latch is inserted in described jack and described bulge loop and plug casing are sealed connected together, described Socket casing is provided with some jacks, described plug casing is provided with some latches, and described jack is positioned at the space that described bulge loop surrounds.During use, plug makes latch insert jack along moving axially of sealing ring, plug casing cooperates bulge loop along the radial compression sealing ring of sealing ring, sealing ring produces strain and plug casing and bulge loop is sealed connected together, and makes water to enter plug and socket through the junction of plugs and sockets.Since the direction that is squeezed of sealing ring be sealing ring radially and the direction that plug inserts be sealing ring axially, keeping of sealing ring sealing function is to rely on bulge loop mated plug housing but not dependence plugs and sockets connection power, Gu the sealing function of plugs and sockets is independent of one another with the connection effect of plugs and sockets.Bulge loop can be realized with the sealing of Socket casing affixed by bonding mode.
As preferably, described sealing ring sealing is fixed in described plug casing.In the plug insertion process, when sealing ring all contacted with bulge loop, then sealing ring can produce the effect that plug inserts that hinders.This is established technical scheme and makes that in the plug insertion process, the inhibition that sealing ring produces is little, and the convenience during insertion is good.
As preferably, described plug casing outer surface is provided with the O-ring seal mounting groove, and described sealing ring sealing is connected in the described sealing ring mounting groove.Convenient during the installing/dismounting sealing ring.
Preferred as another, described sealing ring sealing is fixed in described bulge loop.
As preferably, described bulge loop is arranged with the sealing ring gland, and described sealing ring gland is provided with in-flanges, and described sealing ring is pressed and sealed by described in-flanges and is connected on the described bulge loop end face.Unclamp the sealing ring gland to the chip hold down of sealing ring, namely can easily sealing ring be taken out between in-flanges and bulge loop, convenient during the dismounting sealing ring.The sealing ring gland can by be threaded, mode such as tight fit is fixed on the bulge loop, also can be connected on the Socket casing by screw or button bit.
As preferably, described sealing ring gland is with being interference fit between the described bulge loop.Simple in structure and compactedness good, can not make sealing ring produce displacement in the process of fixed seal ring gland.
As preferably, when being provided with in described latch is inserted in described jack, the outer surface of described plug casing is connected to together annular protrusion with the inner peripheral surface sealing of described sealing ring, and described projection is sealed connected together with described plug casing.In the process of plug plug, just can influence plug, the convenience when having improved the plug plug when having only projection to contact with sealing ring.
As preferably, described projection is structure as a whole with described plug casing.Convenient during making.
As preferably, described bulge loop is structure as a whole with described Socket casing.Convenient during making.
The utility model also comprises the waterproof cover that covers on described bulge loop.When plug is not inserted on the socket, covers at bulge loop by waterproof cover and to prevent that sealing enters jack.When will inserting socket, plug then waterproof cover is removed.
The utlity model has following advantage: the reduction that plugs and sockets connects power can not exert an influence, neither can cause when sealing ring seals plugs and sockets plugs and sockets to connect the reduction of power, can not accelerate to produce between the plugs and sockets loosening phenomenon yet the sealing effectiveness of sealing ring.
