Abstract
The utility model provides an integral wall bushing, includes insulating base member, insulating base member middle part outer wall fixedly connected with ring flange, insulating base member is provided with a plurality of threading pipes along the even interval of circumferencial direction, insulating base member middle part both sides form first mounting groove and second mounting groove respectively, be provided with the spacer that is located the threading pipe outside on the insulating base member, seted up a plurality of spacing grooves between spacer and each threading pipe. The utility model discloses simple structure, fail safe nature are strong, mechanical strength is high, simple to operate.
Description
Technical Field
The utility model belongs to the technical field of electrical connection, especially, relate to an integral wall bushing.
Background
The wall bushing is also called a wall bushing, a waterproof bushing and a wall embedded pipe, and the waterproof bushing is divided into a rigid waterproof bushing and a flexible waterproof bushing. The ac wall bushing used for electric conduction is classified into a dry capacitive ac wall bushing and a ceramic insulating ac wall bushing, which are called a silicone rubber bushing and a ceramic bushing for short. The bus chamber on the switch cabinet needs to be provided with a wall bushing for connecting electrical inlet and outlet wires between cabinets or functional compartments. The existing wall bushing usually adopts a split structure, is inconvenient to install, is easy to loosen after being used for a long time, and has great potential safety hazard.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide a simple structure, fail safe nature is strong, mechanical strength is high, simple to operate's integral wall bushing.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides an integral wall bushing, includes insulating base member, insulating base member middle part outer wall fixedly connected with ring flange, insulating base member is provided with a plurality of threading pipes along the even interval of circumferencial direction, insulating base member middle part both sides form first mounting groove and second mounting groove respectively, be provided with the spacer that is located the threading pipe outside on the insulating base member, seted up a plurality of spacing grooves between spacer and each threading pipe.
A stepped hole is formed in each threading pipe, and the diameter of the threading pipe positioned on the inner side is larger than that of the threading pipe positioned on the outer side.
The connecting surface of the stepped hole in each threading pipe is in arc transition.
And a plurality of umbrella skirts are arranged on the outer wall of the spacer sleeve.
The first mounting groove and the second mounting groove are of wedge-shaped groove structures.
The insulating base body, the flange plate, the threading pipe and the spacer bush are all made of insulating materials through integral pressing.
Adopt above-mentioned technical scheme, the utility model discloses well insulating substrate, ring flange, threading pipe and spacer all adopt insulating material an organic whole suppression to form, form a whole, simple to operate, and mechanical strength is high, and is reliable and stable, and the insulating problem between installation component and the conductive part has been solved in setting up of spacer, has both realized the miniaturization, has practiced thrift the cost, and mechanical strength is high moreover, and insulating properties is good.
