The present invention relates to a kind of cable cutting heads, including the cable core being made of more copper wires and outer insulation jacket, interior insulation set is provided on the outer surface of each cable core, the outside of the interior insulation set is provided with tape for cables, to returning spring plate, polyvinyl chloride set, copper wire armored layer and spring knitmesh is disposed between outer insulation jacket on the outside of the tape for cables, it is respectively fixedly connected between the returning spring plate, polyvinyl chloride set, copper wire armored layer and spring knitmesh.The present invention can improve the restoring force of cable, effectively under the action of returning spring plate in this way by setting returning spring plate convenient for the Quick-return of cable；Pass through setting polyvinyl chloride set, copper wire armored layer and spring knitmesh, cable is under the action of polyvinyl chloride set, copper wire armored layer and spring knitmesh in this way, the mechanical tensile strength of cable in the construction process can effectively be increased, extend the safety in utilization of cable, it is ensured that the normal work of equipment.
Description
Technical field
The present invention relates to field of cable technology more particularly to a kind of cable cutting heads.
Background technique
The function of charging pile is similar to the fuel charger inside gas station, can be fixed on ground or wall, be installed on public
It builds in (public building, market, Public Parking etc.) and residential area parking lot or charging station, it can be according to different voltage
Grade is that the electric car of various models charges.The input terminal of charging pile is directly connected to AC network, and output end, which is equipped with, to be filled
Plug is used to charge for electric car.Charging pile generally provides two kinds of charging modes of normal charge and quick charge, Ren Menke
It is used with using specific recharged card to swipe the card on the man-machine interactive interface that charging pile provides, carries out corresponding charging side
Operation, the charging pile display screens such as formula, charging time, cost data printing can show the data such as charge volume, expense, charging time.
Charging pile (bolt) is able to achieve timing, meter electric degree, meter amount of money charging, can be used as citizen's power purchase terminal.It is filled simultaneously for raising is public
The efficiency and practicability of electric stake (bolt) will increase the function that one (bolt) is filled more and charged for electric bicycle successively from now on.
Cable is usually every group by several or the cable of similar rope that several groups of conducting wires (every group at least two) are twisted
Mutually insulated between conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.
Currently, cable cutting head machinery tensile strength when charging to automobile is inadequate, it is easy to lead when automobile starts suddenly
The fracture of cable is sent a telegraph, and is easily deformed when cable is squeezed, the service life of cable is influenced.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of cable cutting head.
The present invention is achieved through the following technical solutions:
A kind of cable cutting head, including the cable core being made of more copper wires and outer insulation jacket, each described cable
It is provided with interior insulation set on the outer surface of core, the outside of the interior insulation set is provided with tape for cables, outside the tape for cables
Side is to being disposed with returning spring plate, polyvinyl chloride set, copper wire armored layer and spring knitmesh between outer insulation jacket, and described time
It is multiple to be respectively fixedly connected between latch plate, polyvinyl chloride set, copper wire armored layer and spring knitmesh.
As the preferred technical solution of the present invention, polyvinyl chloride set with a thickness of 2mm~3mm.
As the preferred technical solution of the present invention, the copper wire cross sectional shape in the copper wire armored layer is round or flat.
As the preferred technical solution of the present invention, it is fixedly connected between the spring knitmesh and outer insulation jacket.
Compared with prior art, it the beneficial effects of the present invention are: the present invention is by setting returning spring plate, is returning in this way
The restoring force of cable can be improved under the action of multiple latch plate, effectively convenient for the Quick-return of cable；By the way that polychlorostyrene second is arranged
Alkene set, copper wire armored layer and spring knitmesh, such cable under the action of polyvinyl chloride set, copper wire armored layer and spring knitmesh,
The mechanical tensile strength of cable in the construction process can effectively be increased, extend the safety in utilization of cable, it is ensured that equipment
It works normally.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1, Fig. 1 is the structural diagram of the present invention.
A kind of cable cutting head, including the cable core 1 being made of more copper wires and outer insulation jacket 8, each described electricity
Interior insulation set 2 is provided on the outer surface of cable core 1, the outside of the interior insulation set 2 is provided with tape for cables 3, the cable
The outside of band 3 is to being disposed with returning spring plate 4, polyvinyl chloride set 5, copper wire armored layer 6 and spring between outer insulation jacket 8
Knitmesh 7 is respectively fixedly connected with, in this way between the returning spring plate 4, polyvinyl chloride set 5, copper wire armored layer 6 and spring knitmesh 7
The restoring force of cable can be improved, effectively under the action of returning spring plate 4 convenient for the Quick-return of cable.
Wherein polyvinyl chloride set 5 with a thickness of 2mm~3mm, such polyvinyl chloride set 5 can play preferable fire-retardant
Effect, and the copper wire cross sectional shape in the copper wire armored layer 6 is round or flat, the spring knitmesh 7 and outer insulation jacket 8
Between to be fixedly connected.Cable, can be effective under the action of polyvinyl chloride covers 5, copper wire armored layer 6 and spring knitmesh 7 in this way
Increase cable mechanical tensile strength in the construction process, extend the safety in utilization of cable, it is ensured that the normal work of equipment.
In the description of the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ",
" fixation " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integral；It can be machinery
Connection, is also possible to be electrically connected；It can be directly connected, two elements can also be can be indirectly connected through an intermediary
The interaction relationship of internal connection or two elements.It for the ordinary skill in the art, can be with concrete condition
Understand the concrete meaning of above-mentioned term in the present invention.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
