Description
Technical field
The invention belongs to be electrically connected technical field, and in particular to one kind is used to that electrical circuitry equipment or electromechanics will to be wired to
The electric wire switching device monomer of the wiring hole of product and the more monomer integral type electric wire switching devices being made up of it.
Background technology
The mode that wiring hole coordinates housing pin is usually taken when connecting power line in existing electrical circuitry equipment or electronic product
The electrical connection established between wire and internal circuit.As shown in Figure 8 and Figure 9, the connecting line construction one of electrical circuitry equipment or electronic product
As include the ＇ of housing wiring hole 10, the ＇ of housing pin 20 and the ＇ of binding post 30, wherein：The ＇ of binding post 30 is used to connect internal circuit
And External cable, the ＇ of housing pin 20 are used to wire being pressed to the ＇ of binding post 30, the ＇ of housing wiring hole 10 is used for through and held
Receive wire；The ＇ of screwed hole 301 for coordinating the ＇ of housing pin 20 is provided with ＇ of terminals 30 and for grafting cable
The ＇ of terminal connections hole 302, the position of the ＇ of terminal connections hole 302 and the ＇ of housing wiring hole 10 position face.
Following point be present in above-mentioned connecting line construction：
1st, interface should not match.Because the wire gauge for needing to connect is different, the diameter of wire rod varies, and various electricity
Power is equipped or the attachment structure of electronic product is intended to standardize, that is, certain a kind of product generally only provides a kind of cable connection
Interface, it is difficult to adapt to the line demand of different size cable in the market and application, often occur that thick cable connects in practice
Thin wiring hole either Thin cable connect thick wiring hole situation --- either wiring efficiency or quality of connection all can be by shadow
Ring；Furthermore the diameter of wire rod due to needing to connect is different, the area or quality of connection of its electric connection established are also therefore
And showing larger difference --- thin wire electrical-contact area is small, and heavy gauge wire electrical connection area is big.
2nd, when it be rope-lay strand to need the cable that connects, due to housing screw effect and/or assembling when twisting, cut with scissors
The stranded conductor being connected together is very easy to scatter, and then causes the electrical connection between cable and binding post to be failed.
3rd, line is hindered.Housing pin directly compresses wire, it is possible to meeting damage wires, causes Joint failure.
4th, couple corrosion easily occurs for copper aluminium contact position.The binding post of existing electrical circuitry equipment and electronic product typically uses
Metal copper material.And for cost or weight in terms of consideration, commercially available cable is typically using density is smaller, electric conductivity is not also poor
Aluminium material.When copper aluminium is directly connected to, because the current potential of two kinds of metals is different, it is likely that can be because electrification occurs between copper aluminium
Learn corrosion and cause the conductive power of junction to decline.This point is even more serious in wet environment, often has at copper-aluminium transition bright
Aobvious 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, application
In once repeatedly there is the situation of wiring point heating even burning apparatus or wire.
To solve the above problems, the connecting line construction of power equipment or electronic product can be technically improved, however,
Connecting line construction is improved while can be related to many-sides such as the external structure of power equipment or electronic product, internal connections
Variation, cost is higher, and the cycle is longer, it is impossible to adapts to existing application demand, can not solve the tool to have put into production use
Have connecting line construction as shown in Figure 8 and Figure 9 or with similar connecting line construction (such as be only provided with binding post a screwed hole or
More screwed holes) power equipment or electronic product practical difficulty.
The content of the invention
It is an object of the invention to provide a kind of electric wire switching device monomer, is mismatched with solving above-mentioned interface, copper aluminium connects
The place of connecing may occur couple corrosion and easily damage electric wire or cause stranded conductor to scatter during directly with housing pin line ball
