Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily, it is clear that described embodiment is the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
As shown in Figures 1 to 6, the present invention provides a kind of wire clamp insulating sheaths for low-voltage customer wiring, main
Purpose is by while saving material cost, realizing the full mistake of wiring for the integrated design of wire-clamping device and insulating shield
Journey is dielectrically separated from protection, and main feature is as follows:
The wire clamp insulating sheath includes wire-clamping device 1 and the insulating shield 2 protected to wire-clamping device 1, clamp dress
It is electro-insulating rubber material that 1, which is set, with insulating shield 2.Insulating shield 2 includes the main sheath 201 for wire-clamping device 1 to be fixedly mounted,
The electrical verification earthing rod 202 connecting with main 201 inside wire-clamping device 1 of sheath is provided on main sheath 201, it can be without main sheath
201 directly implement electrical verification or ground connection operation from external electrical verification earthing rod 202, simplify program, improve working efficiency.
Wiring cover board 203 is connected on the main sheath 201, the secondary shield of suit electrical verification ground connection on the electrical verification earthing rod 202
Set 204 can prevent the mistake due to operator from touching, or be collided, and unnecessary casualties or equipment is caused to damage
It is bad.
Preferably, it is connected by a snap between main sheath 201 and wiring cover board 203, and main sheath 201 and wiring cover board
Adsorption magnet 218 is provided between 203 contact face.When completing an operation every time, using adsorption magnet 218 by main shield
Set 201 is temporarily adsorbed with wiring cover board 203, operating personnel's electric shock during preventing, and after the completion of all wiring work, then is covered and is connect
The buckle of line cover board 203 is locked completely.
Wire-clamping device 1 is fixed in main sheath 201 mainly using two ways: first way, wire-clamping device 1 pass through one
Body formed connection type is connected in the cavity being equipped with inside main sheath 201, and such mode structure is simple, saves material；The
Two kinds of modes are fixedly installed with clamp system 205 in the cavity of main sheath 201, and it is fixed that wire-clamping device 1 passes through clamp system 205
In main sheath 201, the wire-clamping device 1 of such mode can dismantle installation or replacement at any time, be applicable in various types of
The fixed installation of wire-clamping device 1.
Wiring cover board 203 and electrical verification are grounded when secondary sheath 204 is dismantled and lose in order to prevent, it is preferred that wiring cover board 203 with
It is connected between main sheath 201 by the first connecting band 206, electrical verification is grounded between secondary sheath 204 and main sheath 201 to be connected by second
Tape splicing 207 connects.
As preferred embodiment: when wiring, if wire-clamping device 1 is mounted on main sheath in a manner of integrally connected
In 201, then directly toward 1 internal wiring of wire-clamping device, if wire-clamping device 1 is fixed in main sheath 201 by clamp system 205,
Wire-clamping device 1 is then sleeved on to the inside of the clamp system 205 of main sheath 201 first, peels off wire insulation later, toward clamp
The inside of device 1 connects main line and subordinate line, quickly covers the wiring cover board 203 of main sheath 201 later, completes wiring, this
Process may be implemented wiring overall process and be dielectrically separated from protection, ensure the safety of operator.
When electrical verification and ground connection, the secondary secondary sheath 204 of 204 electrical verification of sheath ground connection of electrical verification ground connection is unpluged first and passes through the second connecting band
207 connect with main sheath 201, prevent from losing, and carry out electrical verification or the operation of ground connection later, remove ground connection after completing service work
Line finally puts on electrical verification and is grounded secondary sheath 204, completes work.
For clamp system 205 for the clamping to wire-clamping device 1, main includes being set to main 201 cavity bottom wall surrounding of sheath
Four locating pieces 208, locating piece 208 is configured to the arc towards the wire-clamping device 1, the outside of the locating piece 208
It is provided with mobile sliding block 209, the cavity bottom wall of the main sheath 201, which corresponds on the position of the mobile sliding block 209, to be provided with
The inside of the sliding slot 210 matched with mobile sliding block 209, the sliding slot 210 is equipped with compressed spring 211, the compressed spring 211
Both ends be separately connected 210 cell wall of sliding slot and the mobile sliding block 209.
When needing to install wire-clamping device 1, four locating pieces 208 are broken into two with one's hands toward outside first, later put wire-clamping device 1
It is placed in the centre of locating piece 208, under the pressuring action of compressed spring 211, is moved on sliding block 209 along the promotion of sliding slot 210
Locating piece 208 compresses wire-clamping device 1, prevents its lateral displacement.
Meanwhile upper and lower displacement, the lower surface of wiring cover board 203 occur during clamping for wire-clamping device 1 in order to prevent
It is provided with and compresses the insulation of 1 upper surface of wire-clamping device and rise part 212.The part 212 that rises has flexible elasticity, can be on wire-clamping device 1
Surface forms extruding force.
It is cylindrical structure that electrical verification, which is grounded secondary sheath 204 with electrical verification earthing rod 202, and electrical verification is grounded secondary sheath 204 and is connected to
The outside of electrical verification earthing rod 202；It is considered that the secondary sheath 204 of electrical verification ground connection may be insecure due to contacting with electrical verification earthing rod 202
And it falls off.The inner wall that electrical verification is grounded secondary sheath 204 is provided with undercut 213, and the low wall of undercut 213 passes through adjustable spring 214
It is connected with ball 215, the outer wall of electrical verification earthing rod 202 is provided with towards intramedullary expansion for limiting the limited ring groove of ball 215
216。
If wire-clamping device 1 is directly connected to electrical verification earthing rod 202, dust and other impurities may directly pass through electrical verification earthing rod
202 channel enters the inside of wire-clamping device 1, causes the pollution of route, even will cause fault when serious.Therefore it is pressing from both sides
It is connected between line apparatus 1 and the inner end of electrical verification earthing rod 202 by electrical verification earth lead 217.Make electrical verification earthing rod 202 and clamp
Device 1 is indirectly connected with by electrical verification earth lead 217.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
