Further, wire comprises the first wire be connected between power input terminal and second source lead-out terminal, and is connected to the second wire between second source lead-out terminal and the first power output terminal.
Further, the common port of the first wire and the second wire is connected on the contact pin of needle stand formula connector of described second source lead-out terminal, and the junction of this connection is wrapped up by described insulation filler.
Further, the insulation crust of second source lead-out terminal is rubber ring or plastic ring.
Further, the insulation filler of second source lead-out terminal is PUR.
Further, second source lead-out terminal is printed circuit connector.
Present invention also offers a kind of circuit board testing system, comprise circuit board and above-mentioned alternating-current electric connecting line, it is characterized in that, described circuit board comprises power input port and transformer, the first input end of described alternating-current electric connecting line is connected with AC power, described first output is connected with the power input port of described circuit board, and described second output is connected with the input of described transformer.
The invention has the beneficial effects as follows: can be two load supplyings simultaneously, with low cost, safe, reliable, and do not have Danger Electric shock risk, and do not have the situation of loose contact.
Accompanying drawing explanation
Fig. 1 is the structural representation of the AC power connecting line of the embodiment of the present invention one.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, for embodiment of the present invention alternating-current electric connecting line comprises power input terminal 20, first power output terminal 30 that is connected with wire 10 and second source lead-out terminal 40, first power output terminal 30 is in parallel with second source lead-out terminal 40.
The power input terminal 20 of this alternating-current electric connecting line is the connector plug being applicable to arbitrarily alternating current transmission, first power output terminal 30 is the plug of printed circuit connector, conveniently coordinate with the needle stand on circuit board, second source lead-out terminal 40 comprises insulation crust, fluid sealant and needle stand formula connector from outside to inside, needle stand formula connector is placed in insulation crust, filling with sealant between needle stand formula connector and insulation crust, play effect that is fixing, that seal and insulate, this needle stand preferred is VH series needle stand, and sealing glue is PUR.
Wire 10 comprises the first wire 11 of being connected between power input terminal 20 and second source lead-out terminal 40 and is connected to and the second wire 12 between second source lead-out terminal 40 and the first power output terminal 30.First wire 11 and the second wire 12 common port be jointly connected on second source lead-out terminal 40, in the present embodiment, its connected mode is that the first wire 11 and the second wire 12 are welded on the round needle of the needle stand of second point power output terminal 40, with fluid sealant, weld parcel is covered again, play the effect of reinforcing and insulating.
The AC power connecting line that the embodiment of the present invention provides can be two load supplyings simultaneously, and because printed circuit connector is all with shell fragment and buckle structure, connects the reliability coordinated higher, not easily occur the phenomenon such as loose contact, electric leakage.
Present invention also offers a kind of circuit board testing system, circuit board is the control board in electric equipment further.This circuit board comprises power input port and transformer, when circuit board normally uses, power input port access power supply, is generally 220V or 380V alternating current, by this port, electric energy is supplied transformer again, each electronic devices and components after transformer transformation on supply circuit plate.
But when testing circuit board, need test the electric property of the power interface of circuit board and transformer, then need to access power supply respectively.During test, by the power input terminal 20 incoming transport power supply of alternating-current electric connecting line, the first power output terminal 30 is connected with the power input port of described circuit board, and second source lead-out terminal 40 is connected with the input of described transformer.
Power input on circuit board is needle stand formula socket, is connected with the printed circuit connector formula plug as the first power output terminal 30; As the needle stand formula socket of second source lead-out terminal 40, be connected with the printed circuit connector formula plug on transformer inputs lead-out wire.Connection like this, what wire can be made to connect is reliable and stable, does not have Danger Electric shock risk, and can realize powering for while circuit board power source interface and transformer input interface, convenient test, quick, safety.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
