Abstract
The utility model discloses a waterproof junction box and relates to the technical field of electric power wiring tools. The junction box comprises a box body and wire inserting holes. Positions, which are corresponding to the wire inserting holes, inside the box body are each provided with a glue pouring baffle plate; each glue pouring baffle plate comprises two side plates and an end plate; the two ends of each end plate are in sealing connection with one end of each side plate; the other ends of the two side plates are in sealing connection with the inner wall of the box body at the two sides of each wire inserting hole; the bottom of each glue pouring baffle plate is in sealing connection with the base plate of the box body; and each end plate is also provided with an axial line, and a through hole which has an axial line superposed with the axial line of a corresponding wire inserting hole and has the same diameter as the corresponding wire inserting hole. The glue pouring baffle plates are additionally arranged between cables and the box body of the junction box so that when a silica gel is filled in the baffle plates for sealing, the connection positions of the cables and the box body of the junction box can be sealed, moisture is prevented from entering the inside of the junction box along a sealing line, the junction box is prevented from being burnt and damaged, and the service life of the junction box is prolonged.
Description
Technical field
The utility model relates to electrical power wiring frock technical field.
Background technology
The cable of existing junction box for photovoltaic module and terminal box body are connected with two kinds of modes, and a kind of is by fastening nuts mode, and cable is penetrated to terminal box inside afterwards by nut check cable and box body; Another kind is by ultrasonic bonding mode, is about to cable and penetrates behind terminal box inside, and upper lower lock block is connected cable by ultrasonic bonding with box body.During ultrasonic bonding, the phenomenon that can not combine completely while being prone to lower lock block welding, thereby cause and between lower lock block, have gap, moisture enters terminal box inside along gap, when terminal box is arranged on assembly normal work, there is electric spark, burn terminal box, and then burn whole assembly, there is serious quality accident.More and more use in the market ultrasonic bonding mode fixed cable and terminal box body, terminal box quality is crucial.The concrete mode of connection of the two is: nut check mode, and be about to cable and penetrate behind terminal box inside, by nut check cable and box body, between nut and cable, be added with waterproof apron, reach both contact position waterproof sealings.Ultrasonic bonding mode, is about to cable and penetrates behind terminal box inside, and upper lower lock block is connected cable, seal with box body after by ultrasonic bonding, reaches waterproof sealing.When but assembly normal mounting is worked out of doors, no matter be nut check mode or ultrasonic bonding mode, all there is hidden danger in the waterproof sealing effect of the contact position of cable and box body, while raining, moisture all easily enters terminal box inside along cable, assembly is when normal work, electric current, by occurring electric spark, burns terminal box, even burns whole assembly.
So need now a kind of terminal box, can finely play the effect of waterproof, the gap sealing that can be fine cable be entered to terminal box when inner and between terminal box by plug wire hole is good, guarantees not can rain to enter into the inside of terminal box.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of waterproof junction box, this terminal box can finely play the effect of waterproof, the gap sealing that can be fine cable be entered to terminal box when inner and between terminal box by plug wire hole is good, guarantees not can rain to enter into the inside of terminal box.
For addressing the above problem the technical scheme that the utility model takes, be: a kind of waterproof junction box, comprise box body, plug wire hole, it is characterized in that being equipped with one group of encapsulating baffle plate at inner corresponding each plug wire hole of box body, described encapsulating baffle plate comprises two side plates and an end plate, the two ends of described end plate are all tightly connected with one end of side plate, the inboard wall of cartridge of the other end of two side plates and plug wire hole both sides is tightly connected, the bottom of described encapsulating baffle plate and the base plate of box body are tightly connected, and are also provided with dead in line and the identical through hole of radius of axis and plug wire hole on end plate.
Preferred described two side plates are all connected with end plate is vertical.
Preferred described two side plates all with vertical connection of inboard wall of cartridge of plug wire hole both sides.
The bottom of preferred described encapsulating baffle plate is connected with the base plate of box body is vertical.
The beneficial effect that adopts technique scheme to produce is: between cable and terminal box body position, increase encapsulating baffle plate, in the inside of baffle plate, pouring into silica gel seals, cable and terminal box body link position are sealed, stop moisture to enter terminal box inside along potted line, prevent that terminal box from burning, increase terminal box useful life.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail: this terminal box comprises box body 1, plug wire hole 2, at inner corresponding each plug wire hole 2 of box body 1, be equipped with one group of encapsulating baffle plate, described encapsulating baffle plate comprises two side plates 3 and an end plate 4, the two ends of described end plate 4 are all tightly connected with one end of side plate 3, the other end of two side plates 3 is connected with box body 1 inner wall sealing of plug wire hole 2 both sides, the base plate 5 of the bottom of described encapsulating baffle plate and box body 1 is tightly connected, on end plate 4, be also provided with the dead in line of axis and plug wire hole 2, and the through hole 6 that radius is identical.Described two side plates 3 are all connected with end plate 4 is vertical.Described two side plates 3 all with vertical connection of box body 1 inwall of plug wire hole 2 both sides.The vertical connection of base plate 5 of the bottom of described encapsulating baffle plate and box body 1.
At plug wire hole 2 places with box body 1 internal communication, be provided with an encapsulating cavity being formed by encapsulating baffle plate that can carry out encapsulating, the structure that forms a U-shaped by means of three blocks of plates, then by 5 sealings of the base plate of the bottom of three blocks of plates and terminal box inside, the inner wall sealing of the open end of opposite side and box body 1, so just, formed a cavity, when using, first cable is inserted in plug wire hole 2, and through the through hole 6 on end plate 4, inside toward cavity pours into silica gel again, after solidifying by the gap sealing between cable and plug wire hole 2, guaranteed that rainwater can not enter into the inside of terminal box.
The beneficial effect that adopts technique scheme to produce is: between cable and terminal box body position, increase encapsulating baffle plate, in the inside of baffle plate, pouring into silica gel seals, cable and terminal box body link position are sealed, stop moisture to enter terminal box inside along potted line, prevent that terminal box from burning, increase terminal box useful life.
