Description
Technical field
The utility model relates to a kind of insulation of cable intermediate joint to be quickly converted protective shell with straight-through.
Background technique
With the fast development that urban electric power cable run is built, among the high pressure connected between realization power cable
Connector has been widely used, and insulation intermediate connector is frequently encountered in the application of transition joint changes and do in straight-through indirectly
The case where head is used, traditional way are carried out and are connect, the connection of this kind of mode in outside using earth cable crimping ground terminal
It is unreliable, and sealing waterproof difficult to realize.
Utility model content
The utility model solves the deficiencies in the prior art and provides a kind of structure simple, easy for installation, at low cost electricity
Cable transition joint insulation is quickly converted protective shell with straight-through.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of insulation of cable intermediate joint is quickly converted protective shell with straight-through, including for being sleeved on cable intermediate joint
The first shell and second shell in outside, the first shell are connected with second shell by insulated connecting piece, the first shell
Body includes the first cylinder and the first earthing rod for connecting with the first cylinder, the second shell include the second cylinder and with second
The second earthing rod and third earthing rod of body connection.The present apparatus is mounted on the outside of cable intermediate joint, when needs are as in insulation
Between connector in use, only one of earthing rod on the second cylinder need to be blocked with insulation sealing cap, by the first cylinder and
After coaxial ground cable or the crimping of common earth cable grounding connection pipe is respectively adopted in other two earthing rod on second cylinder
Extraction；When need as straight-through transition joint in use, only needing on the first earthing rod and the second cylinder on the first cylinder
One of them in two earthing rods is attached with bend pipe or earth cable, then by another earthing rod on the second cylinder with general
Logical earth cable is drawn after being crimped with grounding connection pipe, to simply and easily realize in insulation intermediate connector and lead directly to
Conversion between transition joint.Present apparatus structure is simple, easy to use, substantially increases joint efficiency, and not in conversion
It will affect the leakproofness of structure.
Further, the insulated connecting piece be on the outside of first shell and second shell by way of injection molding or rotational moulding at
One layer of insulating sheath of type.
Further, first earthing rod is welded on the first cylinder, second earthing rod, the welding of third earthing rod
On the second cylinder.
Further, the connecting flange for connecting with other protective shells is also welded on second cylinder.To side
Just the connection of adjacent protective shell.
Further, it is equipped with seal groove at the joint face of the connecting flange, is equipped in the seal groove and uses O-shaped sealing
Circle.
Due to using said mechanism, the present apparatus can easily turn between insulation intermediate connector and straight-through transition joint
Change, when need as insulation intermediate connector in use, only need to by one of earthing rod on the second cylinder insulate sealing cap into
Row blocks, and coaxial ground cable or common earth cable is respectively adopted in other two earthing rod on the first cylinder and the second cylinder
With extraction after the crimping of grounding connection pipe；When need as straight-through transition joint in use, only needing first on the first cylinder
Earthing rod is attached with one of them on the second cylinder in two earthing rods with bend pipe or earth cable, then by the second cylinder
Another upper earthing rod is drawn after being crimped with common earth cable grounding connection pipe.
In conclusion the utility model can realize being quickly converted for insulation intermediate connector and straight-through transition joint, structure letter
It is single, easy for installation, at low cost.

Specific embodiment
The utility model in order to better understand is made utility model further detailed with reference to the accompanying drawing and embodiment
Describe in detail bright, but the embodiments of the present invention is not limited only to this, and the protection scope of the utility model is also related to art technology
Personnel according to the utility model design it is conceivable that equivalent technologies mean.
As shown in Figs. 1-5, a kind of cable intermediate joint insulation is quickly converted protective shell, including first shell 1 with straight-through
With 3 two parts of second shell；The first shell 1 includes the first cylinder 11 and the first earthing rod connecting with the first cylinder 11
12, it is attached by the way of welding between the first cylinder 11 and the first earthing rod 12；The second shell 3 includes second
Body 31 and the second earthing rod 33, third earthing rod 34, the connecting flange 32 connecting with the second cylinder 31, the second cylinder connect with second
Ground column 33, third earthing rod 34 and connecting flange 32 are attached by the way of welding；Outside first shell 1 and second shell 3
Side forms one layer of insulating sheath 2 by way of injection molding or rotational moulding, plays insulation protection to first shell 1 and second shell 3 and makees
With, and first shell 1 and second shell 3 are connected into an entirety；
