The existing wire harness conduction test is usually used for testing a single wire harness, but the mode of testing the single wire harness is only suitable for wire harnesses with larger diameters, but cannot be used for the terminal wire harness 3, because the wire harness diameter of the terminal wire harness 3 is smaller, the test on the single terminal wire harness 3 cannot ensure that the terminal wire harness 3 can be stably fixed, and because the terminal wire harness 3 is generally in a cluster shape, the quantity is larger, the test workload on the single terminal wire harness 3 is larger, and the accuracy of a test result cannot be ensured. So to the terminal pencil 3 of finished product, the interface at terminal pencil 3 both ends is connected with test equipment respectively usually, and the process of connecting all needs the manual work to operate, the interface of terminal pencil 3 tip needs to guarantee the parallel and level state before being connected with the interface on the test equipment, and can't guarantee the structure of terminal pencil 3 tip and the interface on the test equipment can accomplish when being connected and be in the parallel and level state during manual test, just so can appear wearing and tearing when connecting, the interface that leads to test equipment appears not hard up condition after long-time test, and then leads to test equipment to connect the malfunctioning condition, finally leads to test result to appear the deviation.

In order to avoid the above-mentioned situation, the testing device is further improved, the abrasion of the interface of the end part of the terminal wire harness 3 to the interface of the testing device is reduced when the interface is connected, during the test, the terminal wire harness 3 is sequentially pushed into the supporting groove 21 from the opening end of the supporting groove 21, the terminal wire harness 3 is not a single wire harness but is composed of a plurality of wire harnesses, and two ends of the plurality of wire harnesses are respectively arranged on two interfaces, namely, the terminal wire harness 3 tested at the place is in the state of the terminal wire harness 3 in the finished product state. The upper interface and the lower interface of the terminal wire harness 3 are respectively positioned at the upper part and the lower part of the supporting groove 21, the rated number of terminal wire harnesses 3 can be accommodated in the supporting groove 21, and after the rated number of terminal wire harnesses 3 are sequentially pushed into the supporting groove 21, test equipment is started, and the test equipment comprises an upper connecting seat 4 positioned at the upper part of the bracket 2 and a lower connecting seat 5 positioned at the lower part of the bracket 2.

When the upper connecting seat 4 is connected with the upper interface of the terminal wire harness 3, the pressing rod 231 also moves along the horizontal direction, and it is worth noting that when the terminal wire harness 3 is pushed into the supporting groove 21 in sequence at the beginning of the test, the pressing rod 231 is located at one side of the supporting groove 21, so that the terminal wire harness 3 can smoothly move along the extending direction of the supporting groove 21, after the terminal wire harness 3 is placed, the pressing rod 231 located at one side of the supporting groove 21 starts to move, the pressing rod 231 moves along the horizontal direction towards the extending plate 22, during the moving process of the pressing rod 231, the pressing rod 231 sequentially passes through the second gap and the first gap, and generally a plurality of single wire harnesses in the terminal wire harness 3 can be in a mutually staggered state, if the wire harnesses are not straightened during the test, the situation that the connection of the terminal wire harness 3 and the interface of the terminal wire harness 3 appears at the time of the test. The pressing rod 231 can avoid the situation, when the pressing rod 231 moves along the horizontal direction, the pressing rod 231 passes through between adjacent single wire harnesses in the terminal wire harness 3, the extending plate 22 arranged on one side of the terminal wire harness 3 is used for supporting the single wire harnesses, if the adjacent single wire harnesses in the terminal wire harness 3 have bending phenomenon, and when the extending plate 22 is not arranged on one side of the terminal wire harness 3, the single wire harnesses bent in the horizontal wire harness 3 can be pushed open by the pressing rod when the pressing rod 231 moves horizontally towards the terminal wire harness 3, and after the extending plate 22 is arranged, the single wire harnesses in the horizontal wire harness 3 are blocked by the extending plate 22, so that the pressing rod 231 can pass through between the adjacent single wire harnesses, namely, the pressing rod 231 can pass through the second gap smoothly. At this time, the pressing bar 231 located in the second gap is located at the upper end of the single wire harness, and then the pressing bar 231 moves from top to bottom in the vertical direction, the pressing bar 231 moves from top to bottom in the second gap, the length of the terminal wire harness 3 is the rated size, the descending distance of the pressing bar 231 is the same as the rated length of the terminal wire harness 3, and when the pressing bar 231 descends to the lowest position, the terminal wire harness 3 can be completely straightened.
