Pass through technique scheme, it is filled with the seal made by soft material and extrusion in wiring skeleton frame on casing lateral wall, after electric wire passes through the wiring hole entrance casing on seal, the driving assembly effect extrusion being placed on extrusion is allowed to deform upon, thus lateral compression seal with reduce the aperture of wiring hole so that wiring hole laminating electric wire, stop rainwater to enter in casing along wiring hole, thus reach waterproof sealing effect.

Preferably, described driving assembly includes the bolt being arranged on extrusion, and described bolt includes head and screw rod, and threaded on described screw rod have nut, and described head and nut are conflicted respectively on the both sides end face of extrusion.

Pass through technique scheme, head and nut are placed on the both sides end face of extrusion, the both sides that nut on adjusting screw rod makes head and nut constantly compress extrusion are allowed to deform upon, thus lateral compression seal reduces wiring hole aperture, make wiring hole laminating electric wire, eliminate the connection gap of electric wire and seal.

Preferably, described driving assembly also includes being located at the first pad on the end face of extrusion both sides and the second pad, and described first pad is placed between extrusion and head, and described second pad is placed between nut and extrusion.

By technique scheme, during adjusting nut, the first pad and the second pad wind are not fitted on the both sides sidewall of extrusion, and the first pad and the second pad can be uniformly dispersed the pressure suffered by extrusion, and preventing from excessively compressing makes extrusion damage.

Preferably, it is provided with sealing ring between described first pad and head.

By technique scheme, sealing ring can slow down the abrasion between head and the first pad and prevent rainwater from penetrating in extrusion from its junction, makes extrusion accelerated ageing.

Preferably, described wiring skeleton frame includes the pedestal being located on box inside wall and is fixedly connected on pedestal and extends to the compressing member outside casing, described compressing member is provided with locking member, described locking member is arranged in pedestal and its end thread is connected with fixture, and described fixture is conflicted with pedestal and is connected.

Pass through technique scheme, it is positioned at the compressing member outside casing to be sheathed on the pedestal of box inside by the locking member which is provided with, the threaded locking member of fixture, make wiring skeleton frame be fixed on casing, improve the steadiness of wiring skeleton frame, change in time during convenient damage.

Preferably, described casing being hinged with case lid, described casing is provided with the protruding frame for case lid of fitting, and described case lid is provided with the sealing strip with protruding frame fitted seal casing.

By technique scheme, during case lid Guan Bi casing, sealing strip on protruding frame laminating case lid, make case lid can seal box house.

Preferably, described protruding frame is provided with the flange for gluing, sealing bar away from the end of casing.

By technique scheme, flange increases the contact area of protruding frame and sealing strip, improves sealing property.

In sum, what the utility model in contrast to prior art has the beneficial effect that this junction box's sealing means is simple, good seal performance, and can regulate wiring hole pore size according to the thickness accessing electric wire, effectively prevents rainwater from penetrating in junction box.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, junction box is made up of casing 4 and 1 two parts of case lid, the side of case lid 1 is articulated with on casing 4, casing 4 is provided with protruding frame 6, and protruding frame 6, away from the end flange 13 of casing 4, increases the contact area with case lid 1, case lid 1 is provided with the sealing strip 5 for fitting with flange 13, the width of sealing strip 5 is more than the width of flange 13, the fully wrapped around firmly flange 13 of energy, reaches to seal water-proof function.

As shown in figures 1 and 3, it is connected with wiring skeleton frame 3 on the lateral wall of casing 4, wiring skeleton frame 3 includes pedestal 10 and compressing member 11, pedestal 10 is placed in inside casing 4, compressing member 11 is placed in outside casing 4, the threaded compressing member of fixture 12 11 being provided with by pedestal 10, thus pedestal the 10th, casing 4 and compressing member 11 three are fixed.
