Description
Technical field
The present invention relates to a kind of electrical socket, in particular for the electrical socket of electric warming bag, it has reliable operation, the characteristics that maintain easily.
Background technology
The electrical socket of prior art; Such as Chinese patent 99208427.X " general-using type electrical socket "; It is many jacks mobile socket common in our daily life; It connects each parts with screw, because the flexibility and the particularity of electric warming bag bag body, directly grafting at the electric warming bag bag on one's body obviously and be not suitable for.It is the socket coupler of contact pin that Chinese patent 00202330.X " electric warming bag " discloses electric contact piece, and it is called fixing with being connected of bag body.Chinese patent 200620058490.1 " attaching plug of electric warm water bag ", then the product with listing already is the same, discloses the electric warming bag socket with cover plate.The Chinese patent 200620053880.X electric warming bag socket of structure " improve " discloses being connected to glued joint and adding screens between the part of socket, and the water filling stopple of electric warming bag is hidden by pedestal; Chinese patent 02223120.X " explosion-proof electric hot-water bottle " discloses the shutoff chamber of perfusion fluid sealant; Chinese patent 200820064772.1 " a kind of device for plugging that is used for flexible electric warming bag " discloses and has been fixed with the conical plug that small end is the mushroom barb on the lead, leans on it to fill in dried wet soft interface opening and comes the structure of leak stopping.
Usually the bag body is flexible, if the parts that link to each other with the bag body in the socket are hard, it is that high strength is non-leakage that its connecting portion is difficult at high temperature realize, low-cost again.Therefore, in fact the enforcement of the overwhelming majority is, these parts use the identical or close material manufacture of performance with bag stature material, use the PVC lining such as the bag body, and then these parts are also used the soft pvc material, links into an integrated entity with HF hot melt again, and this is that cost is the most cheap; If a bag body use rubber, then these parts are also used rubber, and at the mid-raw rubber of faying face, it is cooked technology such as to vulcanize again, their are refined strike up partnership.Parts that should link to each other with the bag body are called soft separator, but its double as container also holds socket coupler and other element, and it is with liquid in the bag and its isolation.The socket coupler, it is connected with soft separator because soft material is stressed yielding, can't be directly fixing with other simple and direct mechanical connection manner of check bayonet socket or screw or the like effectively, therefore, the prior art employing to be that the embedding colloid connects fixing.In addition, electric components such as thermostat are housed usually in the soft separator, the stress deformation of soft material makes that external force was applied to and is prone to cause damage on the electric component when electric warming bag used, and the bond of embedding colloid and soft separator is not high yet, and the socket coupler is drawn out easily.The problem of bringing thus is: assembly technology is loaded down with trivial details, and product quality is not high; Can only dismantle with destructiveness after the moulding, have fault to keep in repair, scrappage is high.
The electric heating body that lead connected is immersed in works in the liquid; This liquid can be the water of conduction; Therefore; No matter lead passes the dried interface entering liquid that wets of soft separator still is that the electric heating body port passes dried district of the dried wet interface entering of isolation seat, and this all can produce the dried wet sealing problem of soft interface opening on the electrical safety aspect.Practice shows that the space of lead internal copper heart yearn also might become the passage of leak of liquid.Glued joint by embedding design in order to connect fixing for prior art; Because each parts in the socket are very low to the soft pvc adhesion without special processing such as epoxy glue to the difference of the affinity degree height of colloid, so; Faying face is can not the everywhere all fine and close to link to each other; Can only get it and design desirable affixed effect, produced not outside its purpose, have the sealing effectiveness on the actual electric safe floor face, especially its unspecial sealing of wet soft interface opening of doing and handle.Then under high temperature or external force effect, can lose efficacy very soon by the dried wet soft interface opening of the stifled sealing of plug.Electric teapot, electric heater are hard electrothermal tube and the hard encapsulation process structure of doing wet interface opening: and electrical socket of electric heating bag be soft and or low elasticity, the yielding encapsulation process of doing wet interface opening of being heated, what reality it can not get and effectively uses for reference from electric teapot, electric heater there.And the sealing of ordinary hot water bag water filling port does not relate to the electrical safety aspect, thus less demanding, there is drainage to take place also the time in actual the use.The enforcement product of prior art, the actual product that has gone on the market; Antiseep is the problem that expectation solves always better, and the seepage of electric warming bag liquid makes electric elements sparking in the socket, and the severe patient thermostat is by broken ring; Cause bag to split cruelly, the actual life of product is very short.
In addition, known technology is informed: working of plastics uses metal insert usually for increasing its connecting portion intensity, like the attaching nut of screw.Metal nuts is everlasting and the mating surface place annular knurl of plastics is processed to improve bond strength; When injection moulding, be placed in the mould; This plastic material performance must be hard in normality; So-called hard, be exactly that it has sufficiently high modulus of elasticity and tension and compression, bending strength, can be consolidated in the plastic during part completion.Then being difficult to implement for soft plastics should technology.
