Description
Technical field
The present invention relates to a kind of cradle, is specifically a kind of waterproof cradle.
Background technology
Cradle is a kind of for electrical equipment charging accessories, it is widely used in electric tool, torch etc., its structure generally comprises cradle body, described cradle body comprises holder, positive terminal and the negative pole shell fragment that insulating materials is made, one end of described holder is connected with charging circuit board, the other end of holder is provided with charging socket, described positive terminal is fixedly connected in holder, and the tail end of positive terminal contacts with charging circuit board, the free end of positive terminal is arranged in the charging socket of holder; The tail end of described negative pole shell fragment is fixedly connected on holder, and holder is provided with one to stretch into opening in holder for negative pole shell fragment free end; The cradle of this structure does not possess water-proof function, and water can enter in charging circuit board along the charging socket of holder through opening, thus damages circuit board.Also there is the cradle of some waterproof at present, as the chargeable flashlight of Chinese patent 2005100489235, cradle in technical scheme disclosed in it is fixed on cylindrical shell by subterminal position, and barrel tip is releasably connected with end cap, when charging, end cap is backed out, end cap is tightened when not charging, end cap plays the effect of isolated water, there is certain water-proof function, but end cap to be taken off when charging, and the end cap taken off easily is lost again, operation is very inconvenient like this, and waterproof effect is poor.The and for example flashlight with waterproof charging device of Chinese patent 200420066855, in technical scheme disclosed in it, during charging, charhing unit is plugged in flashlight body, make the transfer point of charhing unit contact flashlight body exposes and charges with the charging part that flashlight body seals, charhing unit is taken off after charging terminates, because charging part that flashlight body exposes and flashlight body seal, therefore this flashlight has water-proof function; But must charhing unit be loaded onto when charging, therefore operate cumbersome, and its production cost be higher, be not easy to large-scale popularization and use.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defect of above prior art, easy to operate when providing a kind of charging, the low and waterproof cradle of good water-proof effect of production cost.
Technical solution of the present invention is, there is provided a kind of waterproof cradle with following structure: it comprises the holder made with insulating materials, positive terminal and negative pole shell fragment, the tail end of described negative pole shell fragment is fixedly connected on holder, and holder is provided with the opening that a confession negative pole shell fragment free end stretches into holder endoporus, described holder is arranged with a protective sleeve made with conductive material, the two ends of described protective sleeve are all tightly connected with holder outer circle wall, and opening and negative pole shell fragment are positioned at protective sleeve, described negative pole shell fragment contacts with the inwall of protective sleeve.
After adopting above structure, waterproof cradle of the present invention compared with prior art, have the following advantages: this waterproof cradle adopts dexterously and be arranged with a protective sleeve made with conductive material on holder, the two ends of described protective sleeve are all tightly connected with holder outer circle wall, and opening and negative pole shell fragment are positioned at protective sleeve, described negative pole shell fragment contacts with the inwall of protective sleeve, this protective sleeve makes the opening on holder and negative pole shell fragment seal, thus make water can not enter inner charging circuit board through opening from the charging socket of holder, thus protect the safety of circuit board, this charging socket structure is simple, easy to make and there is good waterproof effect, directly by the charging socket of power connection connection fixing base during charging, operation is very easy, and the low price of protective sleeve, make the cost of this cradle low, be therefore convenient to large-scale popularization and use and torch, hand-operated tools etc.
As preferably, described protective sleeve is copper protective sleeve.Because negative pole shell fragment contacts with the inwall of protective sleeve, therefore protective sleeve plays the effect connecting negative pole.
As preferably, the wall thickness of described protective sleeve is 0.5 millimeter ~ 5 millimeters.
As preferably, the wall thickness of described protective sleeve is 1.5 millimeters.
