However, a corresponding testing device is not available on site, and at present, the pulling force can be only pulled by hands, so that the pulling force is difficult to ensure to be the required force, and the testing effect cannot be achieved if the force is too small, so that the installation effect is difficult to ensure; excessive force tends to pull the pin out, requiring labor and time to re-install. If the wiring harness contact pin is not installed in place in the inspection stage, the contact pin can be retracted when the plug is installed, so that open circuit or virtual connection is caused, and system faults are caused.

The force application metering member 10 includes a housing 11 and a gauge 12 disposed in the housing 11. The housing 11 comprises an upper shell 112, a lower shell 113 and a watch case 111, the upper shell 112 and the lower shell 113 forming a receptacle for receiving the meter 12 and a part of the clamping member 20, with the other part of the clamping member 20 protruding from the housing 11 for clamping the connector harness pins. The case 111 is accommodated in the upper case 112 to cover and protect the display 121 of the meter 12.
As shown in fig. 3, the grip member 20 is a scissor-type member extending longitudinally from a trailing end to a leading end, the scissor-type member including a grip portion 21, a force application portion 22, and an operation portion 23, the rotation shaft 26 dividing the grip member 20 into the grip portion 21 and the force application portion 22, the operation portion 23 being connected to the force application portion 22 for operating the force application portion 22.
The clamping portion 21 includes a clamping end 55 at a top end thereof, a pair of cylindrical collets 59 connected to the clamping end 55, the cylindrical collets 59 extending in an extending direction of the connector harness pins for clamping the connector harness pins. The clamp portion 21 can be closed and opened by the force applying portion 22 so that the pair of columnar clamps 59 can clamp and release the connector harness. The force application portion 22 extends from the grip portion 21 in the longitudinal direction for opening and closing the grip portion 21. The operating portion 23 is connected to the force applying portion 22 to apply an opening force to open the clamp portion 21 and a closing force to close the clamp portion 21 to the force applying portion 22.
The connecting member 30 connects the urging portion 22 of the clamping member 20 to the urging force measuring member 10, causes the urging force measuring member 10 to apply a detection force for verifying the mounting force to the connector harness through the clamping portion 21, and measures the magnitude of the detection force. As can be seen from fig. 3, the meter 12 is mounted in the housing 11, and the force application portion 22 and a part of the clamping portion 21 of the clamping member 20 are longitudinally slidably accommodated in the housing 11.
As shown in fig. 3 and 4, the clamp member 20 includes a pair of levers 25, and the pair of levers 25 are connected together by a rotating shaft 26 at a crossing overlapping portion of the pair of levers 25 so that the levers 25 can pivot about the rotating shaft 26. Each lever 25 includes a grip lever section 56 formed at the grip portion 21, a force application lever section 57 formed at the force application portion 22, an operation lever section 58 formed at the operation portion 23, and a rotation shaft hole 54 formed between the grip lever section 56 and the force application lever section 57. The operation lever section 58 applies an opening force and a closing force to the force application lever section 57, and the force application lever section 57 is opened and closed.

Thus, after the pair of columnar clamps 59 clamp the connector harness pins, the connector harness pins can be pulled outward in the longitudinal direction by the pair of levers 25, thereby measuring whether the mounting force of the connector harness pins is satisfactory.
To open a pair of columnar collets 59 to insert a connector harness pin between the pair of columnar collets 59, the lever section 58 of the operating portion 23 extends from the force application lever section 57 at a position near the rear end of the force application lever section 57 in a direction opposite to the gripping direction of the corresponding gripping lever section 56 to the button end 51 of the lever section 58, i.e., the lever section 58 extends from the force application lever section 57 near one side of the housing 11 generally transversely to the longitudinal direction toward the other side of the housing 11 and extends the button end 51 of the lever section 58 out of the housing 11 so as to press the button end 51 inwardly outside the housing 11.

The operating portion 23 further includes a compression spring 27, the compression spring 27 being disposed between the pair of engagement ends 53 of the pair of operating lever segments 58 and having a biasing force due to compression, so that the biasing force of the compression spring 27 acts on the urging lever segment 57 through the operating lever segment 58, so that the urging lever segment 57 is pivoted inward, whereby the clamp lever segment 56 is in the clamped state. When an external pressing force acts on the button end 51, the external pressing force acts on the urging rod segment 57 through the operation rod segment 58 against the biasing force of the compression spring 27, so that the urging rod segment 57 pivots outward, whereby the clamp rod segment 56 is in the open state.
As shown in fig. 5 and 6, to facilitate gripping of the connector harness pins, the gripping surfaces of the cylindrical collets 59 that grip the connector harness pins are configured to have a profile that corresponds to the profile of the connector harness pins. Preferably, the clamping portion 21 further comprises a clamping sleeve 28 covering at least the clamping surface of the cylindrical clamping head 59, the clamping sleeve 28 is made of rubber, and the clamping surface of the clamping sleeve 28 is textured to generate a large friction force.

The flexible cable 38 is configured such that the force application lever section 57 can pivot relative to the rotary shaft 26 when the clamp lever section 56 is opened and closed, and when the clamp lever section 56 is in the clamped state, the detection force applied to the force application gauge member 10 is transmitted to the clamp member 20 through the flexible cable 38, and at the same time, the display 121 displays the reading of the detection force.
As shown in fig. 2 and 3, windows are provided on both sides of the housing 11, through which the lever section 58 protrudes from the inside of the housing 11, so that the lever section 58 can move inward with respect to the housing 11. The top end of the housing 11 is provided with an opening so that at least a portion of the clamping bar segment 56 can protrude out of the housing 11 through the opening, whereby the clamping bar segment 56 can open and close about the rotary shaft 26 and clamp the connector harness pins.
As such, when it is desired to detect the mounting force of the connector harness pins, the following operations may be performed:
1) holding the upper housing 112 and the lower housing 113 by hand;
