Description
Technical field
The present invention relates to power cable connection areas, and in particular to one kind will be for that will be wired to electrical circuitry equipment or electromechanics
The electric wire switching device of product.
Background technology
The mode of wiring hole cooperation housing pin is usually taken when connecting power line in existing electrical circuitry equipment or electronic product
Establish the electrical connection between conducting wire and internal circuit.As is illustrated by figs. 11 and 12, the connecting line construction of electrical circuitry equipment or electronic product
Shell wiring hole 111, connecting terminal 112 and housing pin 113 are generally comprised, wherein：Connecting terminal 112 is for connecting internal electricity
Road and External cable, housing screw 113 are used to conducting wire being pressed to connecting terminal, and shell wiring hole 111 is used for across and holds
Receive conducting wire；The threaded hole 122 for coordinating housing pin and the end for grafting cable are provided on the connecting terminal 112
Sub- wiring hole 121（Figure 12）, the position in the terminal connections hole 121 and the position of shell wiring hole 111 are corresponding.
There are following points for above-mentioned connecting line construction：
1, interface mismatches.Since the wire gauge for needing to connect is different, the diameter of wire rod varies, and various electric power
The connection structure of equipment or electronic product is intended to standardize（It is connect that is, certain a kind of product usually only provides a kind of cable connection
Mouthful）, it is difficult to adapt to the line demand of different size cable in the market and in application, it is thin that thick cable connection is often will appear in practice
Wiring hole either Thin cable connect thick wiring hole the case where --- either wiring efficiency or quality of connection can all be affected；
Furthermore the diameter of wire rod due to needing to connect is different, the area or quality of connection of the electric connection established also therefore and
Showing larger difference --- thin wire electrical-contact area is small, and it is big that heavy gauge wire is electrically connected area.
2, when it is rope-lay strand to need the cable that connects, due to housing screw effect and/or assembly when twisting, hinge
The stranded conductor being connected together is very easy to scatter, and then the electrical connection between cable and connecting terminal is caused to be failed.
3, hinder line.Housing pin directly compresses conducting wire, it is possible to which meeting damage wires cause Joint failure.
4, couple corrosion easily occurs at copper-aluminium transition.The connecting terminal of existing electrical circuitry equipment and electronic product generally uses gold
Belong to copper material.And the considerations of in terms of cost or weight, commercially available cable generally use that density is smaller, electric conductivity is not also poor
Aluminium material.When copper aluminium is directly connected to, since the current potential of two kinds of metals is different, it is likely that can be because electrochemistry occurs between copper aluminium
Corrode and the conductive power of junction is caused to decline.This point is even more serious in wet environment, often has at copper-aluminium transition apparent
Visible powdered alumina occurs.
Above-mentioned various problems are single, partly or entirely integrate, and the quality of connection of joint can be caused undesirable, apply
In once repeatedly there is wiring point fever even burning apparatus or the case where conducting wire.
To solve the above problems, the connecting line construction of power equipment or electronic product can be technically improved, however,
The various aspects such as the external structure to power equipment or electronic product, internal connection are improved while can be related to connecting line construction
Variation, cost is higher, and the period is longer, does not adapt to existing application demand, can not solve the tool to have put into production use
There is connecting line construction as is illustrated by figs. 11 and 12 or with similar connecting line construction（For example only there are one threaded holes for setting on connecting terminal
Or multiple threaded holes）Power equipment or electronic product practical difficulty.
