Brief description of the drawings

Fig. 1 is the structural representation of the embodiment of the utility model test equipment one；

1 is battery, and 2 be battery connector, and 3 be empty pin test board, and 4 be test machine.

Realization, functional characteristics and the advantage of the utility model purpose will be described further referring to the drawings in conjunction with the embodiments.

Embodiment

It should be appreciated that specific embodiment described herein is not used to limit this only to explain the utility model Utility model.

A kind of empty pin test board of the utility model offer, reference picture 1, in one embodiment, the sky pin test board 3, including Connectivity port and test port, the connectivity port are used to be connected with battery connector 2, and the test port is used for and test machine 4 connections, the pin of the test port include all pins corresponding with battery connector：Power pins, empty pin and work( Can pin, in test port, the empty equal short circuit one of pin on battery connector with the non-conterminous function of sky pin Pin, not short circuit between the empty pin.

The power pins are the pin for being connected with power supply, and the empty pin is also not transmit any signal over the ground Or the pin as voltage pin, the functional pin are the pin in addition to power pins or empty pin.

When being tested using the empty pin test board of the present embodiment battery connector, if the empty pin on battery connector With adjacent pin short circuit（Two empty pins on battery connector are non-conterminous）, due to the empty pin and function of test port Pin（It is different from above-mentioned adjacent pin）Short circuit again, then test port test power pins and functional pin function whether When normal（As whether voltage/current/resistance is normal）When, there are following two situations：

1st, the power pins of test port are shorted to by the empty pin on battery connector with the power pins short circuit Test port is abnormal with the data on the functional pin of the sky pin short circuit, causing to test out, thus can determine whether that the sky draws Pin is short-circuited in battery connector；

2nd, the functional pin of test port is shorted to by the empty pin on battery connector with the functional pin short circuit Test port is abnormal with the data on the functional pin of the sky pin short circuit, causing to test out, thus can determine whether that the sky draws Pin is short-circuited in battery connector；

For example：Battery connector is provided with eight pins, is divided into four rows of one row of pin two and sets, a row be P+, NC1, TH, P-, another row are P+, ID, NC2, P-, and wherein NC1, NC2 is empty pin, and P+, P- are power pins, and TH, ID are work( Energy pin, then need whether the P+ for testing battery connector occurs short circuit with NC1, TH and NC1, ID and NC2, P- and NC2：
