Embodiment
For above-mentioned technical proposal, now lift a preferred embodiment and be specifically described with reference to diagram.Referring to Fig. 1 to Fig. 3,
Fuse box of the present utility model, including shell body, inner housing, wherein.
Inner housing 1, using being integrally formed.Inner housing includes the cavity of accommodating high breaking fuse, is opened in the bottom of cavity
Provided with multiple open-works as heat emission hole 11.Both sides in interior shell cavity respectively integrally formed with accommodating hole, inner housing with
After shell body assembles, the upper end of accommodating hole is located in shell body cavity.Hollow both ends open is provided with accommodating hole
Conducting metal sleeve 12, conducting metal sleeve typically use the preferable brass wire of electric conductivity.
Internal thread is offered in conducting metal sleeve.The both ends of conducting sleeve are concordant with the both ends of accommodating hole or slightly prominent.
The conducting connecting part 18 of one c-type structure is arranged on the outside of accommodating hole, coats side and its upper and lower ends of accommodating hole, i.e., this is led
The upper and lower ends of electrical connector are respectively overlay in the upper and lower ends of accommodating hole, and conductive gold is corresponded in the upper and lower ends of conducting connecting part
Belong to and offer corresponding screwed hole at the internal thread hole of sleeve.Conducting connecting part material is red copper.Screw 13, which is each passed through, to be located at
The screwed hole of the c-type conducting connecting part at conducting metal set both ends, is then locked in the internal thread of conducting metal sleeve.In inner casing
The open-work passed through for battery circuit connecting end is offered on body cavity body sidewall.In assembling, battery terminal connections pass through open-work, attach
C-type conducting connecting part lower end outside at the conducting metal sleeve end face in inner housing, screw 13 connect through battery
End and conducting connecting part are locked in conducting sleeve one end, so as to which battery terminal connections and conducting connecting part, conducting sleeve are conductive
Connection.The gusset piece of fuse is located at the outside of the conducting connecting part of the conducting metal sleeve upper end surface in shell body, screw
It is locked at after through gusset piece, conducting connecting part in conducting metal sleeve.By the locking of the screw of conducting metal sleeve upper end,
So as to which the gusset piece of fuse and battery terminal connections are passed through into c-type conducting connecting part and screw, conducting metal sleeve, two kinds of screw
Connected mode is conductively connected.The connection of the gusset piece and battery terminal connections of fuse relies primarily on c-type conducting connecting part company
Connect, and red copper electric conductivity is better than brass conductive performance, therefore, by increasing c-type conducting connecting part, can strengthen fuse with
The conduction property of battery terminal connections, reduce connection resistance.For convenience, battery terminal connections can be arranged to connecting contact pin shape,
Connecting contact pin is fixed on to the outside of conducting connecting part by screw, is then provided with socket on battery circuit, during assembling, only
Connecting contact pin need to be plugged in socket can be such that battery circuit is connected with fuse gusset piece.After fuse damages, it is only necessary to
Shell body is opened, backs out screw, changes fuse, it is not necessary to take whole housing apart replacing.
In inner housing end face, the cavity of inner housing and conducting metal sleeve periphery form the company contacted with battery bag fitting
Junction.Screw 14 is offered respectively on four angles of joint face.One end of screw 14 extends to below joint face and sealed
Close, form the enclosed type screw of one end open.In the periphery of screw 14 neck spaced apart for offering a ring shape,
Sealing ring 15 is provided with the neck.
Shell body 2, profile are hat-shaped, are raised up formed with cavity, after assembling, the conducting metal of inner housing
One end of sleeve is then in the cavity of shell body.In the cavity periphery of shell body, the joint face of corresponding inner housing, also form
Corresponding joint face.On the joint face of outer shell cavity periphery side, a circle neck is offered around cavity, is set in neck
It is equipped with a circle sealing ring 21.On the joint face positioned at the outside of sealing ring 21, the position of the screw 14 of corresponding inner housing, accordingly open
Screw provided with corresponding connection.In assembling, inner housing joint face is attached on the inwall C in battery bag, and shell body connects
Junction is attached on the outer wall outside battery bag, and bolt 16 locks shell body and inner housing through the screw on shell body and inner housing
Fasten in battery bag.Due to being provided with a circle sealing ring in the cavity periphery of shell body, therefore, after assembling, water without
Method enters shell body cavity hence into battery bag by joint face.Set in addition due to being set in the screw periphery of inner housing
There is the sealing ring sealed for connecting screw hole, and the screw of the connection on inner housing is the closure spiral shell of one end closing
Hole, therefore, even if water is entered in screw by the gap between screw and bolt, due to having the presence of screw periphery sealing ring, water
Also will not be entered by the gap at the joint face between inner housing and battery bag inwall in battery bag.In order to further improve resistance
Sealing enters battery bag, can open up neck in the screw periphery of connection at outer housing connection surface, and sealing is set in neck
Circle, while be provided with sealing ring on the contact surface that bolt contacts with end surface of screw hole and block water out of screw and bolt-clearance entrance
In screw at housing, the security performance of Fuse box is further improved.
Fuse box of the present utility model makes to melt by the structure design of conducting metal sleeve, conducting connecting part and screw
More convenient, the reduction maintenance cost of the more transformation of disconnected device.By increasing c-type conducting connecting part, enhancing fuse is connected with battery
The conduction property at end, reduce connection resistance；By Double-insurance sealing, water has been blocked to enter the passage of battery bag, pole from every side
Big degree improves the security performance after Fuse box installation.
