Description
Technical field
The invention belongs to electrical connection technical field, the many monomers integral type electric wire switching device being specifically related to a kind of electric wire switching device monomer for the wiring hole by being wired to electrical circuitry equipment or electronic product and being made up of it.
Background technology
Existing electrical circuitry equipment or electronic product, when connecting power line, take wiring hole to coordinate the mode of housing pin to set up electrical connection between wire and internal circuit usually.As shown in Figure 8 and Figure 9, the connecting line construction of electrical circuitry equipment or electronic product generally comprises housing wiring hole 10 ＇, housing pin 20 ＇ and binding post 30 ＇, wherein: binding post 30 ＇ is for connecting internal circuit and External cable, housing pin 20 ＇ is for being pressed to binding post 30 ＇ by wire, housing wiring hole 10 ＇ is used for through and holds wire; Described terminals 30 ＇ is provided with for coordinating screwed hole 301 ＇ of housing pin 20 ＇ and terminal connections hole 302 ＇ for grafting cable, the position of described terminal connections hole 302 ＇ and the position of housing wiring hole 10 ＇ just right.
There is following point in above-mentioned connecting line construction:
1, interface should not mate.Owing to needing the wire gauge difference connected, the diameter of wire rod varies, and the syndeton of various electrical circuitry equipment or electronic product trends towards standardization, also be, a certain series products only provides a kind of cable connecting interface usually, to be difficult to adapt on market and the line demand of different size cable in application, practice often to occur the situation that thick cable connects thin wiring hole or Thin cable and connects thick wiring hole---be that wiring efficiency or quality of connection all can be affected; Moreover owing to needing the diameter of the wire rod connected different, the area of its electric connection of setting up or quality of connection also therefore show larger difference---thin wire electrical-contact area is little, and heavy gauge wire electrical connection area is large.
2, when the cable needing to connect is rope-lay strand, due to the effect of housing screw and/or twisting when assembling, hinged stranded conductor is very easy to scatter, and then causes the electrical connection between cable and binding post to lose efficacy.
3, line is hindered.Housing pin directly compresses wire, likely can damage wires, causes Joint failure.
4, easily there is couple corrosion in copper aluminium contact position.The binding post of existing electrical circuitry equipment and electronic product generally adopts metallic copper material.And for the consideration of cost or weight aspect, commercially available cable generally adopts the aluminium material that density is less, electric conductivity is not poor yet.When copper aluminium directly connects, because the current potential of two kinds of metals is different, the conduction power of junction is caused to decline because of there is electrochemical corrosion between copper aluminium possibly.This point is even more serious in wet environment, and copper-aluminium transition place often has obvious visible powdered alumina to occur.
Above-mentioned various problem is single, partly or entirely integrate, and the quality of connection of joint can be caused undesirable, once repeatedly occurred the situation of wiring point heating or even burning apparatus or wire in application.
For solving the problem, technically can improve the connecting line construction of power equipment or electronic product, but, connecting line construction is improved to the external structure that simultaneously can relate to power equipment or electronic product, many-sided variations such as inner connection, cost is higher, cycle is longer, existing application demand can not be adapted to, can not solve put into production use there is connecting line construction as shown in Figure 8 and Figure 9 or there is the power equipment of similar connecting line construction (such as binding post being only provided with screwed hole or more screwed hole) or the practical difficulty of electronic product.
Summary of the invention
The object of the present invention is to provide a kind of electric wire switching device monomer, to solve, above-mentioned interface does not mate, couple corrosion may occur in copper aluminium junction and directly by the problem easily damaged electric wire or cause stranded conductor to scatter during housing pin line ball, the technical scheme taked is:
