The invention relates to a connector for being connected with a storage battery terminal. The connector comprises a clip body, the clip body comprises an insulating plate, at least one surface of theinsulating plate is plated with a conductive layer, and the head end of the insulating plate is provided with a clamping part. The connector is low in manufacturing cost, simple in manufacturing process and suitable for being connected to the storage battery terminal for a long time; after both surfaces of an insulating layer are provided with conductive layers, during the contact between the conductive layers and the storage battery terminal, two contact points are formed between the conductive layers and the storage battery terminal, and the connector has an absolute effect on the precisionof a detection result of a storage battery.
