Disclosed in an apparatus for measuring positively-sensed force of an electrical connector, comprising: a base plate; at least one L-shaped pads, the two L-shaped pads being each affixed to the base plate at an upper end thereof in such an arrangement that ends thereof oppose each other; an elastically deformable sheet provided between the two L-shaped pads, the elastically deformable sheet being affixed to the base plate and formed with a projective measuring region at end thereof; and at least one strain gauge inertly affixed to the elastically deformable sheet, the strain gauge beingconnected to a signal transmitting device that outputs strain value of the strain gauge to a signal amplifying device for display purpose in response to deformation of the elastically deformable sheet. While implementing this invention in measuring positively-sensed clamping force of terminals of an electrical connector, bottom ends of the two L-shaped pads and the projective measuring region of the elastically deformable sheet are inserted between the connector terminals. Since the two L-shaped pads each have a thickness being equal to a thickness of a circuit board into which terminals are inserted and accommodating width of the connector terminals, and since the circuit board has a thickness being less than the thickness of the two L-shaped pads and a transverse gap formed between the connector terminals, the elastically deformable sheet is thus deformed while experiencing lateral pressure exerted by the connector terminals. Strain of the deformed sheet is thus measured by the strain gauges provided thereon. Strain signals are transmitted to the signal amplifying device through the signal transmitting device to acquire the positively-sensed clamping force of the connector terminals effected to the circuit board.
