The invention discloses a test device for testing wear and degradation of contact parts in an electrical connector, belonging to the field of electrical connectors. The test device for testing the wear and degradation of the contact parts in the electrical connector comprises a three-dimensional R-axis sliding table, a contact force sensor, a wire spring clamp, a pin clamp, a force sensor group, an electromagnetic vibration table and a base; the three-dimensional R-axis sliding table and the electromagnetic vibration table are fixed on the base; the contact force sensor is fixed on the three-dimensional R-axis sliding table; the wire spring clamp is fixed on the contact force sensor; a wire spring is fixed on the wire spring clamp; the force sensor group is fixed on the electromagnetic vibration table; the pin clamp is fixed on the force sensor group; a pin is fixed to the pin clamp; and the pin is placed above the wire spring and reciprocates along the axial direction of the pin withthe electromagnetic vibration table. According to the invention, the pin is driven by the electromagnetic vibration table to move at a certain amplitude and frequency, so as to obtain a mechanical environment close to the use of a wire spring type electrical connector, which is closer to the real condition of the parts.
