Description
Technical field
The utility model is related to Low Voltage Electrical Apparatus, especially a kind of RV electric wires definite purpose circuit breaker terminals.
Background technology
Low-voltage circuit breaker abbreviation breaker, it is a kind of existing manual switch effect, but can carry out automatically decompression, it is under-voltage,
The electric appliance of overload and short-circuit protection, breaker terminal on the market, which mostly uses, at present is wound on electric wire on bolt, and passes through spiral shell
The end of electric wire is mutually squeezed with sheet metal and is contacted by the extruding of bolt head, and sheet metal is electrically connected with circuit breaker internal, but
This mode have one disadvantage in that exactly need it is artificial electric wire is first wrapped on bolt, bolt is then tightened again, in this process
In, RV electric wires are easy to be detached from from bolt, it is sometimes desirable to which repeatedly winding could succeed；Also a kind of mode is to unscrew spiral shell
Electric wire end is directly inserted between stud base and sheet metal, then tightens bolt by bolt, the extruding provided by stud base
Power tight contacts between electric wire and sheet metal together, and sheet metal is electrically connected with circuit breaker internal, although this mode is relative to upper
A kind of mode is easier, but for RV electric wires, and the mode only squeezed can still have some copper wire not being extruded to,
It collectively constitutes, disperses between copper wire, mutually shifting one's position also is easy to cause script copper wire by tightly because electric wire is many copper wire
The state of extruding becomes less tight, extremely dangerous over time it is easy to appear loosening and generate spark phenomenon.
Utility model content
A kind of RV electric wires definite purpose circuit breaker terminals are proposed purpose of the utility model is to solve the above problem,
It can quickly realize winding of the RV electric wires on bolt and make wire termination connection more secured.
The technical solution that uses of the technical issues of the utility model solves for：Including bolt, bolt hole, metal wiring film,
The bolt includes disc bolt head, screw rod, and the screw rod is longitudinally divided into left pole-half and right half bar, the left side half
Bar to form central void with right being spaced apart for half bar, and the left pole-half includes upper end A and lower end A, and right half bar includes upper end B
With lower end B, the upper end A medial surface opposite with upper end B is mutually parallel, and the lateral surface of the upper end A and upper end B are to be equipped with
Externally threaded arcwall face, the lateral surface of the lower end A and lower end B be from the top down to the taper surface of contract, the lower end A with
Medial surface opposite lower end B is plane, and the lower end A is shorter than lower end B；The bolt hole is set to the shell upper end of breaker
Inside, including axle center is identical and is sequentially connected logical upper cylinder groove, lower cylinder groove and inverted conical grooves from the top down, it is described on
The open top of cylinder groove is in case top, and the diameter of the upper cylinder groove is more than lower cylinder groove, the diameter of lower cylinder groove is more than
The bottom surface circular diameter of conical grooves, the lower cylinder groove are provided with internal thread and are matched with the external screw thread of screw rod, the upper cylinder groove
Bottom, lower cylinder groove top perimeter be provided with metal wiring film, the metal wiring film is electrically connected with circuit breaker internal circuit
It connects, the upper cylinder groove side is connected with one end of a square groove, and the other end of the square groove is opened on the side of shell, described

Use process and principle：
One end of RV electric wires is exposed to suitably long metal wire, the end of metal wire is put into central hollow from screw rod bottom
Gap efficiently solves the problems, such as that RV electric wire multiply lamettas are difficult to control.Left pole-half is shorter than right half bar, is more advantageous to RV electricity
Line is put into from screw rod bottom.RV electric wires are put into central void and are pushed into bolt head bottom upwards, the external screw thread of screw rod is under
Cylinder groove internal thread matches, and screw rod is screwed into lower cylinder groove, because the bottom circular diameter of conical grooves is less than the straight of lower cylinder groove
Diameter, therefore when screw rod is during being screwed into, left pole-half and right half bar bottom are allowed to mutual because of the conical grooves that diameter becomes smaller
Close extruding force, such RV electric wires are further clamped in central void by left pole-half and right half bar, along with screw rod exists
When screwing in bolt hole, RV electric wires are wound with being rotated on screw rod for screw rod, and bolt head bottom and metal wiring film are by RV
Electric wire squeezes, and makes electric wire and metal wiring film rigid contact.
Because RV wire ends are sandwiched in central void, RV electric wires, RV electric wires are mutually squeezed between left pole-half and right half bar
It as the rotation of bolt is screwed into and is wrapped on screw rod, is then compressed between metal wiring film and bolt head so that RV
Electric wire be well secured and with the good firm contact of metal wiring film, eliminate in the prior art because RV electric wires have a multiply and band
The loosening hidden danger come.
The upper cylinder groove is used for the placement of bolt head, wire end and metal wiring film, realizes that bolt head is located at
Inside surface of shell, safety is increased.
Sometimes electric wire bare metal part can't be all wound on screw rod, and also part meeting is exposed outside, therefore sets
Square groove is set for storing wire end, avoids bare metal line potential threat caused by human body.
Wherein, preferred embodiment is：
The medial surface of the lower end A extends downwardly along upper end A medial surface bottom margin and is gradually distance from right half bar, it is described on
End B medial surfaces and lower end B medial surfaces are generally aligned in the same plane.
Opening is more than the distance between upper end A and upper end B between the lower end A and lower end B, is more advantageous to RV electric wires in this way
It is put into.
The square groove is provided with plastic cover plate with upper cylinder groove top movable, and the side of the cover board is articulated with the top of shell
Face.
The cover board makes terminals and extraneous good isolation, prevents from accidentally touching and water droplet splashes.
The cover board makes for transparent material.
The square groove and upper cylinder groove top movable are provided with electro-insulating rubber plug, the shape of the plug and square groove and upper
The cross-sectional shape of cylinder groove matches, and the plug is flexibly connected with outer casing top surface.
The plug is made of flame retardant rubber material.
The plug makes terminals and extraneous good isolation, prevents from accidentally touching and water droplet splashes.
The utility model has the beneficial effects that：(1) bolt uses the two-part mode in left and right, and RV wire ends are put into left and right
Bolt is then screwed in into bolt hole again among two parts so that the good winding with bolt disposably can be realized in RV wire ends；
(2) one is long and the other is short for left and right two parts bottom of bolt, and screw rod bottom opening is larger, and RV wire ends is more convenient for be put into bolt
Center；(3) bottom is provided with cone space in bolt hole, is more advantageous to after the bottom pyramidal end of bolt enters cone space,
RV wire ends are further clamped among bolt by squeezing together, are further functioned as fixed function by two parts of bolt；
(4) covering device is additionally provided on the outside of terminals, prevent from accidentally touching and splashed with water droplet, it is safer.
