Description

Wire bundle testing apparatus

Technical field

The utility model is about a kind of proving installation, refers to especially a kind of whether Wire bundle testing apparatus of normally of wire harness that is used for testing.

Background technology

About such as vehicle, in or the machines such as large-scale transaction machine, weeder, boats and ships or stacker, owing to be arranged at and have not very short distance between the stream oriented device in these machines, for example: all have such distance between current enter and the light fixture or between control end and the motor (or engine), therefore must therebetween be electrically connected a wire harness.

As shown in Figure 1, these wire harness 1 comprise a plurality of lead units 11 of bringing together each other together, respectively an end of this lead unit 11 and the other end are electrically connected with respectively at least one the first Wiring harness connector 111 and at least one the second Wiring harness connector 112, and first and second Wiring harness connector 111,112 is provided with not shown electrical contact pin.For respectively this lead unit 11 of testing these wire harness 1 normally whether all, therefore be designed with test board 2 as shown in Figure 1, be pasted with the distribution drawing 21 corresponding to this wire harness 1 on this test board 2, by the wiring diagram of joining for this wire harness 1 on the distribution drawing 21, and be installed with a plurality of tools 22 in the mode that is permanently fixed, respectively this tool 22 has a base 221 and (is provided with the electrical jack corresponding with described electrical contact pin, not shown), described wire harness 1 these first, two wire harness connectors 111,112 electrically are plugged in the base 221 of these tools 22 accordingly one by one.

See also Fig. 2, describe as an example of one of them lead unit 11 of described wire harness 1 example.As shown in Figure 2, (in fact the back side of this test board 2 be electrically connected with a plurality of the first connecting lines 91 and a plurality of the second connecting line 92 according to the wiring diagram of joining on the described distribution drawing 21 with being permanently fixed, these are first years old, two connecting

lines

91,92 should be smooth in the back side of test board 2), these are first years old, two connecting

lines

91,92 bases 221 that are electrically connected at these tools 22 be arranged at being connected between the row 23 of place, described test board 2 tops, then be electrically connected with a plurality of the 3rd connecting lines 93 between this connection row 23 and one test machine 9, in other words, connect into the loop of following order: the first Wiring harness connector 111 of this lead unit 11, the base 221 of left end tool 22, this second connecting line 92, be connected in the 3rd connecting line 93 that connects row 23 left sides, test machine 9, be connected in the 3rd connecting line 93 that connects row 23 the right, the first connecting line 91, the base 221 of right-hand member tool 22, and the second Wiring harness connector 112 of this lead unit 11, because this test machine 9 has been set with many group conducting loop sets, therefore, as long as respectively the link position of this lead unit 11 is correct, just can be connected and can tests whether all normally of this lead unit 11 with a conducting loop sets wherein.

But, illustrate with the wire harness that is used in vehicle, same car money also has different variation designs, in addition must there be a lot of car moneys in same depot, in other words, the difference of different car moneys changes design, the wire harness 1 of mending required connection in it is difference to some extent just, therefore, difference for each different car money changes design, just must make an aforesaid test board 2, also described tool 22 and first, two connecting

lines

91,92 are permanently secured to again on these test boards 2 and can't change fully, and causing to have a plurality of bulk storage plants to deposit the no small test board 2 of these sizes.In addition, the cost of each piece test board 2 is about NT $ 20, more than 000, a wire harness manufacturing company is in order to do test to wire harness 1, just must spend quite high cost on manufacturing test plate 2, even also can be because of the car money more and more, or increasing the variation designed, and make test board 2 also more and more, cause also must spending to hire a warehouse or build the warehouse, this point does not obviously meet economic benefit, early by the dirty disease of wire harness manufacturing company for a long time, and never overcome for a long time, before fixing each tool 22, also must hole to test board 2 still more, with first of tool 22, two connecting

lines

91,92 back sides of moving test board 2 to are also fixed, and with first, two connecting

lines

91,92 are electrically connected to connection row 23, and these operations very bother and be time-consuming, take a lot of work.

Therefore, how to design a kind of Wire bundle testing apparatus that can improve above-mentioned the deficiencies in the prior art fully, can test for different wire harness with same Wire bundle testing apparatus, this is the large problem that those skilled in the art desire most ardently solution.
