Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.

As shown in Fig. 1 and Fig. 2A, Fig. 2 B, a kind of novel USB interface charger multichannel ATE test of the utility model is set It is standby, including a upper mold test fixture 11, comprising: pressure plate 2, has multiple AC at the socket 4 with multiple AC standard sockets The measurement circuit plate 5 of measurement circuit is held, the pressure plate 2 has multiple hole locations passed through for trial product plug to be measured.The survey It is fixedly connected between examination wiring board 5 and socket 4 by being set to the column of quadrangle, is led between the pressure plate 2 and socket 4 Cross the connection of compressed spring 3 for being set to two edges of boards edge.In being further provided with inner guiding post 14 in compressed spring 3 on socket, press Entrance hole corresponding with inner guiding post is set on flitch 2, and effect is for upper mold test fixture molding (insertion) guiding, correcting socket Relative position effect between plate and pressure plate.Further, limited block 13 there are two also setting up in pressure plate 2, can prevent Defective work piece is excessively pressed between socket and pressure plate.

The test equipment further includes lower die circulation jig combination 12, including the survey with multiple accommodating trial products 6 to be measured Try station board 7, and the pinboard 8 with multiple ends DC test PCB circuit board.Wherein corresponding each AC standard up and down is inserted Seat, the end AC measurement circuit, DC sections of measurement circuit pcb boards and trial product to be measured 7 form multiple TCH test channels.

Preferably, the pressure plate 2 side opposite with the test station plate 7 is also spirally connected there are two first guide rod 1, described First guide rod is set to binder board ends, the adjustable in length of first guide rod 1, protrude from the length of 6 side of test station plate according to The difference of trial product to be measured can be adjusted correspondingly, and can prevent pressure plate from directly excessively pressing with test station plate, damage Bad trial product to be measured.

A kind of course of work of the novel USB interface charger multichannel ATE test equipment of the utility model embodiment are as follows: When producing USB interface charger, the trial product to be measured 6 after artificial ageing is placed in lower die circulation through automatic assembly line and controls On the test station plate 7 of tool, then lower die circulation jig, which is moved to, is automatically positioned and is tested below upper mold test fixture.

As shown in Fig. 3,4, after upper mold test fixture and lower die circulation jig completion positioning, first guide rod 1 is pressed in advance Trial product 7 to be measured highly adjusts, and then declines together with pressure plate 2 together and pushes down and fix trial product to be measured, realizes first segment Molding.Then, socket 4 and measurement circuit plate 5 are slowly fallen by spring-compressed 3 and inner guiding post 14, slowly contact to The pin of test product avoids damage product, realizes second segment molding, when molding, only pin can be led by pressure plate 2 Body cannot the main body of trial product to be measured cannot pass through pressure plate 2.Limited block 13 prevents socket by external force, and continuing to push causes to press Bad jig and product limit pressure plate down stroke and distance.Pinboard 8 can also connect the end DC, then carry out simultaneously more Channel product test.The utility model can test a variety of USB interface charger pins as shown in Figure 5.

After the completion of test, 4 plate of socket can slowly be risen by compressed spring 3, separated with test product, realized first Section demoulding, the fixed product of pressure plate prevent from taking up when demoulding.Then pressure plate 2 and first guide rod 1 also can then rise, and realize second Section demoulding, defective products can be picked away, and an ATE and Hi-pot test are completed.ATE and Hi-pot test can be real before assembling product Existing modular detection, including output voltage, output electric current, power, the parameters such as overcurrent protection, after avoiding assembling product from completing Due to repair conditions caused by part of module cisco unity malfunction.

Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
