Abstract
The utility model relates to a photovoltaic junction box with an improved cable line locking structure. The photovoltaic junction box comprises a box body, wherein a screw cap connector is arranged on the box body; a cable line is connected with a junction terminal inside the box body; the cable line penetrates through the screw cap connector and is locked through the screw cap; a locking jacket is also arranged inside the screw cap connector; the locking jacket is tubular and one end of the locking jacket is provided with a plurality of lamelliform clamping heads which surround to form an elastic clamping ring; the cable line penetrates through the locking jacket; and the elastic clamping ring is arranged outwards. With the adoption of the locking jacket, the pulling-out force resistance of the cable line and the junction box is increased; and the sealing property is increased by arranging a sealing inner jacket additionally.
Description
Technical field
The utility model relates to a kind of photovoltaic junction box.
Background technology
In the photovoltaic junction box, cable is through nut locking, but in concrete use, cable is firm inadequately with being connected of terminal box, gets loose easily.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of photovoltaic junction box that can improve the architecture advances of cable and terminal box coupling mechanism force.
The technical scheme that the utility model solves its technical problem is:
The improved photovoltaic junction box of a kind of cable locking mechanism comprises box body, and the nut interface is set on the described box body; Stube cable line on the binding post in the described box body, described cable wear described nut interface and through nut locking, also are provided with lock sleeve in the described nut interface; Described lock sleeve is tubular; And the one of which end is provided with some flap clamping heads around forming the elastic clip collar, and described cable is located in the lock sleeve, and described elastic clip collar is provided with outwardly.
As preferably, also be provided with the sealing inner plug cover in the lock sleeve.
Lock sleeve is set in nut, after cable passes the nut interface, also wears lock sleeve; And the sealing inner plug cover is set in the lock sleeve, and then plug sleeve in the tight contact seal of cable is locked through nut again; In the nut locking process, the elastic clip collar on the lock sleeve is further tightened, thus the clamping cables line; Sealing inner plug cover in the lock sleeve increases sealing property, and lock sleeve has increased the anti-slip power of cable and terminal box.
The beneficial effect of the utility model is: the utility model has increased the anti-slip power of cable and terminal box through being provided with of lock sleeve, has also increased sealing property through setting up the sealing inner plug cover.
