In order to solve the technical problems, the utility model provides a terminal pull-out force detection tool of a three-pin connector, which comprises a first tool and a second tool;
the first tool comprises a cylindrical base which is vertically arranged, a slot matched with the connector housing is formed in the upper side of the base, a limiting structure matched with the connector housing is arranged in the slot, a linear notch which radially penetrates through the base is formed in the lower side of the base, and the upper side of the linear notch is communicated with the slot;
the second frock include the block of a vertical arrangement, the block upside is equipped with three vertical blind hole of controlling interval arrangement, the bottom in every vertical blind hole all is equipped with the lower dog with vertical blind hole assorted, lower dog upside is equipped with the spring of vertical arrangement, the spring upside is equipped with the last dog the same with lower dog specification, the upside department that corresponds last dog on the block upper portion position is equipped with one along the horizontal continuous logical groove that runs through three blind hole, be equipped with one with logical inslot assorted horizontal spacer pin, the upside of last dog in the three vertical blind hole all offsets with horizontal spacer pin, correspond every blind hole department on the block bottom position and all be equipped with one along vertical jack that runs through blind hole and block lower part.
For the sake of simple explanation, the tool for detecting the pulling-out force of the terminal of the three-pin connector according to the present utility model is hereinafter referred to as the present tool.
The using method of the tool comprises the following steps: firstly, placing a first tool on a tensile and compressive test bed, placing an opening of a connector to be detected upwards in a slot of the first tool, leading a wire harness at the tail of the connector from top to bottom to pass through the slot and led out from a linear notch, and placing a shell of the connector on a limiting structure in the slot, wherein the upper part of the shell of the connector exceeds the upper side of the slot; and then taking the second tool as an opposite plug structure of the connector to be detected and plugging the connector to be detected, respectively and correspondingly inserting three contact pins in the connector into three jacks at the bottom of the block, starting a pull-pressure test stand power supply, setting the upper limit alarm value of the test stand as the minimum pull-off force value required by the contact pins of the connector, then controlling a pressing column to press the second tool and continuously pressing until the pull-pressure test stand alarms, removing the first tool and the second tool, taking out the detected connector, checking whether the contact pins of the connector have the pull-down movement, and judging whether the minimum pull-off force of the contact pins of the connector reaches the standard.
The tool has the advantages that: the tool adopts the method of pressing the terminals to detect, does not damage the wire harness, has high efficiency, and is suitable for batch production and detection one by one.
