Abstract
The invention provides a multimeter pen and a multimeter with the pen. A slot is arranged in the socket of a multimeter body. A positive wiring terminal and a negative wiring terminal are arranged in the slot. The multimeter pen is provided with a connector which can integrally arrange a positive pen line and a negative pen line. A positive conducting layer and a negative conducting layer which are isolated through an insulating layer are arranged in the insulating shell of the connector. The positive conducting layer and the negative conducting layer are respectively connected with the positive pen line and the negative pen line. The front end of the connector is a socket-connecting end. A positive conducting electrode and a negative conducting electrode which can be electrically connected with the positive wiring terminal and the negative wiring terminal in the slot in a contact way are arranged on the socket-connecting end. By ingeniously improving the structures of the multimeter and the multimeter pen, the connecting structure between the multimeter and the multimeter pen is simplified and the multimeter pen can be used for measurement after one-step socket connection only; and since the two pen lines are integrally arranged, the two pen lines can be prevented from being twisted with each other and even being knotted with each other, and the two pen lines are also convenient to collect.
