Abstract
The utility model discloses a sealing element of a low-voltage cable branch box. The low-voltage cable branch box comprises a box body and a box door capable of being pivoted with the box body, and a circle of protruding shoulders is arranged at the position of a door frame of the box body. The sealing element is characterized by comprising sealing strips sleeved on the protruding shoulders and capable of being tightly attached to the box door when the box door is closed. Thereby, the sealing element is good in sealing effect and attractive and elegant in appearance.
Description
Technical field
The utility model relates to a kind of potted component of cable hut.
Background technology
Along with developing rapidly of State Grid's industry, cable hut is the power distribution equipment rapidly of a kind of development in recent years, it is widely used in outdoor AC three-phase 380V/220V, rated frequency 50Hz, rated current 800A and following low-voltage distribution electrical network, with cable to other user or devices allocation electric energy.Generally, multi-core controlled cable is used in the zone of concentrating from the control room to the field apparatus, and this multi-core controlled cable can connect on-the-spot cable hut, then is transferred to field apparatus from cable hut.Need not change at a distance cable like this when some core of certain root cable or cable goes wrong, process than being easier to.
The low-voltage cable hut that existing market occurs generally comprises the stainless steel casing and is pivotally mounted in chamber door on this casing.Because it is outer that this coupling box is exposed to, so for the needs of electrical safety, usually between casing and chamber door, potted component is set.The doorframe place that existing potted component is included on casing is provided with an outstanding convex shoulder outside of circle, and in the inboard of chamber door to pasting foam strip on the position of convex shoulder, when chamber door was closed, this foam strip can paste convex shoulder like this, thereby played sealing function.Yet there are the following problems for this sealing means: the one, and the easy oxidation of foam strip and being out of shape can cause the decline of sealing effectiveness, thereby can bring to the electric components in casing harmful effect after the use of a period of time; The 2nd,, foam strip pastes on chamber door by glue, can produce harmful effect to the overall aesthetics of coupling box.
The utility model content
The purpose of this utility model is for defects of the prior art, provides a kind of potted component of novel low-voltage cable hut, its good sealing effect and elegant in appearance.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme: a kind of potted component of low-voltage cable hut, described low-voltage cable hut comprises casing and is connected the chamber door that is connected with described casing phase pivot, be provided with a circle convex shoulder at the doorframe place of described casing, it is characterized in that: described potted component comprises sealing strip, described sealing strip is set on described convex shoulder and when described chamber door is closed, can be adjacent to described chamber door.
In addition, the utility model also proposes following attached technical scheme:
Described sealing strip is made by rubber.
Described sealing strip is provided with draw-in groove, and described draw-in groove can be buckled on described convex shoulder closely.
Than prior art, the utility model has the advantage of: establish sealing strip by directly blocking on the convex shoulder on casing, and the sealing bar can be adjacent to chamber door, can reach desirable sealing effectiveness, and its appearance looks elegant is generous.
Description of drawings
