When connecting wires, the main probe 32 is provided with the proper auxiliary probe 33, the position of the probe module 3 is adjusted, and then the plate-shaped detection sample is clamped by the pair of movable clamping plates 2, so that the detection wire connector is pushed forward until the front end of the probe contacts with the wiring points. The front part of the sub-probe 33 may be formed in a needle shape, or may be connected to a plug of a different shape to be suitable for a different connection socket on the sample. If the area of the connection point is larger than the front end area of the main probe 32, the main probe 32 may be directly contacted with the connection point without using the auxiliary probe 33, or the auxiliary probe 33 with a plate-shaped front end may be used to increase the contact area between the probe and the connection point as much as possible, increase the current passing efficiency, and improve the detection accuracy.

The prefabricated secondary probe 33 can be reused for a plurality of times, the installation is very simple, and the fixing of the connector base with the detection sample through the movable clamping plate 2 is very quick and convenient, so that the plate-shaped detection sample can be helped to be connected with wires quickly.

In this embodiment, the auxiliary probe 33 is provided with a spindle-shaped elastic tail handle 331, and the spindle-shaped elastic tail handle is composed of a plurality of arc-shaped elastic pieces 332 which are uniformly distributed at intervals along the circumference;

The slot 321 is a straight slot, and the maximum diameter of the spindle is slightly larger than the diameter of the straight slot. The installation of the auxiliary probe 33 requires that the elastic tail handle 331 is inserted into the slot 321, and the arc-shaped elastic sheet 332 is extruded and deformed during insertion, so that the auxiliary probe 33 is not easy to fall off from the slot 321 under the elastic action, and the current conduction between the main probe 32 and the auxiliary probe 33 is not affected.

When the probe contacts the wiring point, the extension spring 34 forces the front end of the probe to be in close contact with the wiring point, so that the front end and the wiring point are prevented from being separated during the detection process. In addition, the extension spring 34 also forms buffer protection for the detection point in the process of pushing the detection connector to enable the probe to contact with the detection point.

In this embodiment, the connector base 1 has a multi-layer board body, which sequentially includes a front end plate 11, a clamping plate 12 and a rear end plate 13 in the front-rear direction, and a straight through slot 14 extending in the left-right direction is formed in the multi-layer board body;

The function of the spring plate 315 is to push the spring plate 315 forward when the probe module 3 is in the adjusted position, so that it is squeezed between the probe module 3 and the wall of the straight through slot 14 formed by the rear end plate 13, and to limit the movement of the probe module 3 by increasing friction. The pulling piece 3151 is used for conveniently pulling out the spring piece 315, and the probe module 3 can be laterally adjusted again after the spring piece 315 is pulled out. The wings serve to guide the sliding movement of the spring plate 315 and to limit the movement of the spring plate 315 away from the probe module 3.
