As industrial automatization more and more higher and Industry Control requirement are increasingly stricter, accurate, the consumption of binding post gradually on
Rise, with the development of electronics industry, the use scope of binding post is more and more, and species is also more and more.Use at present
Most widely in addition to pcb board terminal, also hardware terminal, nut terminal, spring terminal etc.；Line terminals are to lead for convenience
The connection of line and apply, it is exactly one section of sheet metal for being enclosed in inside ambroin in fact, and two ends have hole may be inserted into lead
Line, has screw to be used to fasten or unclamp, such as two wires, it is sometimes desirable to connect, and needs to disconnect again sometimes, at this moment just can be with
They are connected with terminal, and can be disconnected at any time, it is very square without they are welded or are intertwined
Just it is quick.And it is adapted to substantial amounts of wire interconnection, just there is special terminal block in power industry, terminal box is wiring entirely above
Terminal, individual layer, double-deck, electric current, voltage, common, can break etc..Certain compression joint area is in order to which ensure can
It is abutted against tactile, and guarantees by enough electric currents.
But, it is generating, power supply, most held with electric transmission channel in binding post and the junction that electric power connection line road is connected
Accident-prone position, study carefully itself main reason is that：The contact area of connection is small, loose contact, so that when causing load current
Generate heat and occur accident, and existing binding post can not be powered off in time when breaking down, and security performance is low.
Utility model content
The purpose of this utility model is to provide a kind of safety-type binding post, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of safety-type binding post, including master
Body, described main body one end is provided with terminal hole, and the main body other end sets wire barrel, and the body side face sets radiating group
Part, another side is electrical contact area, is provided with current transformer.
It is preferred that, the current transformer includes iron core, armature winding and secondary windings, and the iron core is U-shaped including two
Iron core, each U-shaped iron core has crossbeam and lateral column, two U-shaped iron cores window staggered relatively to form the iron core；The primary
Winding passes through the window of iron core and is embedded in inside skeleton or is placed in below skeleton；The secondary windings passes through the window of iron core simultaneously
It is wrapped on the lateral column of at least one in two U-shaped iron cores.
It is preferred that, the radiating subassembly includes being provided with least one radiating in heat sink body, the heat sink body
Thin slice, the heat sink body lower end, which is provided between heat-conducting layer, the radiating thin slice, has gap.
It is preferred that, distance is 2mm-3mm between the radiating thin slice.
It is preferred that, the terminal hole is " W " type structure.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model novel in structural design, using W type terminal holes, by increasing capacitance it is possible to increase contact area, improves wiring
Firmness.
(2) in the utility model, the current transformer installed in electrical contact area has high current, low profile and small size
The characteristics of, its security performance is high, when breaking down, being capable of deenergization immediately.
(3) the radiating subassembly heat dispersion that the utility model is used is superior, can quickly disperse the heat in main body.
