The electric connector pulling and inserting mechanism comprises a transmission component 51, an ejection component 52 and a detection component 53, wherein the transmission component 51 can be driven by hand or a motor, when the electrical performance of the product needs to be tested, the transmission assembly 51 can be driven, so that the transmission assembly 51 moves along the first linear direction, the movement of the transmission assembly 51 in the first linear direction can drive the ejection assembly 52 to move in the first linear direction, the transmission assembly 51 and the driving assembly can be connected through a bearing, the transmission assembly 51 can rotate relative to the ejection assembly 52, when the transmission assembly 51 rotates in a first rotating direction, the transmission assembly 51 moves relative to the frame 2 in the direction of the frame 2, thereby pushing the ejection assembly 52 to move in the first linear direction; the ejecting assembly 52 and the detecting assembly 53 may be connected by a cam, and when the ejecting assembly 52 moves along the first linear direction, the cam may eject the detecting assembly 53, so that the detecting assembly 53 moves along the second linear direction, and the detecting assembly 53 may be connected with the product to detect the electrical property of the product.

When the electrical performance of the product is detected, the transmission assembly 51 can be rotated against the first rotation direction, so that the transmission assembly 51 can move along the direction opposite to the first linear direction, that is, the transmission assembly 51 moves relative to the vehicle frame 2 in the direction away from the vehicle frame 2, at this time, the transmission assembly 51 drives the ejection assembly 52 to move along the direction opposite to the first linear direction, and the detection assembly 53 moves along the direction opposite to the second linear direction due to gravity, so that the detection of the product is finished.

The arrangement has the advantages that the positioning structure 3 is connected with the frame 2, so that the positioning structure 3 can be fixed relative to the frame 2, when a product to be detected is hung over the frame 2, the product is inserted into the positioning structure 3, and whether the product meets the specification is detected by judging whether the insertion between the positioning structure 3 and the product is smooth; the limiting block 4 can be fixed by connecting a limiting hole formed in the limiting block 4 with the positioning structure 3, the limiting block 4 is detachably connected with the positioning structure 3, the limiting block 4 can be detached when the product needs to be detected, and the limiting block 4 can be installed on the limiting hole for fixing the product when the product needs to be transported; the transmission assembly 51 is driven to enable the ejection assembly 52 to translate, so that the detection assembly 53 is driven to move towards the direction of the product to be detected, the product is inserted, and the electrical performance of the product can be detected.

As shown in fig. 3, the transmission assembly 51 includes a driving portion 511 and a transmission portion 512, the driving portion 511 is mounted on the frame 2, the driving portion 511 is in screw transmission connection with the transmission portion 512, the transmission portion 512 is movably connected with the ejection assembly 52, and the driving portion 511 is configured to convert the rotation of the transmission portion 512 into the movement of the ejection assembly 52 along the first linear direction.

It should be noted that the driving portion 511 may be provided with a first opening, a circumferential direction of the first opening may be provided with a thread surface, the transmission portion 512 is provided with a spiral structure matched with the thread surface, and the rotation motion of the transmission portion 512 is converted into the linear motion through matching between the spiral and the thread surface. One end of the transmission part 512 may be connected to the ejection assembly 52 through a bearing, the bearing may include an inner bearing, an outer bearing and a ball, one end of the inner bearing may be fixedly connected to the ejection assembly 52, one end of the outer bearing is connected to the transmission part 512, the ball is installed between the inner bearing and the outer bearing, the outer bearing may rotate relative to the inner bearing, when the transmission part 512 rotates relative to the driving part 511, the transmission part 512 moves relative to the driving part 511 along the first linear direction, the transmission part 512 simultaneously pushes the ejection assembly 52 to move along the first linear direction through the ball, and the ball is used for reducing friction between the transmission part 512 and the ejection assembly 52 when the transmission part 512 rotates relative to the ejection assembly 52.

When the cam structure 521 moves in the direction opposite to the first linear direction, the inclined guide groove may pull back the detection assembly 53 protruding out of the frame 2 in the direction opposite to the second linear direction, so that the detection assembly 53 is disconnected from the product, and the detection state of the product is released.

Optionally, the included angle of the inclined guide groove with respect to the frame 2 may be larger than the included angle with the perpendicular to the frame 2, when the cam moves along the first linear direction, the distance that the cam structure 521 moves along the first linear direction is smaller than the distance that the detection assembly 53 moves along the second linear direction, so that the detection assembly 53 can extend outwards with respect to the frame 2 and detect the product, and the time for inserting the detection assembly 53 into the product is saved; the inclined guide groove can be smaller than the included angle of the vertical line of the frame 2 relative to the included angle of the frame 2, the distance of the cam structure 521 moving along the first straight line direction is larger than the distance of the detection component 53 moving along the second straight line direction, the detection component 53 can be slowly inserted into the product, and whether the insertion between the detection component 53 and the product is smooth or not can be more conveniently observed due to the fact that the detection component 53 is slowly inserted into the product.

This is advantageous in that the coupling part 532 is guided by the guide hole while the sensing part 533 coupled to the coupling part 532 is coupled to the product, thereby sensing the product.

As shown in fig. 6 and 7, the vehicle frame 2 includes a limiting plate 21, the limiting plate 21 is provided with a through hole, the detecting portion 533 is inserted into the through hole, and the through hole is used for guiding the detecting portion 533 to move along the second linear direction.

It should be noted that the electrical plug 5331 can detect products within a certain error range, and when the products have a certain error, the electrical plug 5331 can move relative to the housing 5332 and can be used for detecting products within a certain error range. A spring 5333 can be installed between the housing 5332 and the electrical plug 5331, when a product is detected, the electrical plug 5331 is buffered, the electrical plug 5331 is connected to the product, the spring 5333 is compressed, the electrical plug 5331 moves along the opening direction of the accommodating groove, in the process of compressing the spring 5333, the electrical plug 5331 completes position alignment and is inserted into the product, and the movement direction of the spring 5333 can be the same as the movement direction of the electrical plug 5331 relative to the housing 5332. One end of the spring 5333 may abut against an inner side wall of the housing 62, the other end of the spring 5333 may abut against the electrical plug 5331, and the electrical plug 5331 may move in the opening direction of the receiving groove relative to the housing 5332.

This has the advantage that the spring 5333 mounted between the electrical plug 5331 and the housing 5332 prevents the electrical plug 5331 from making hard contact with the product during product testing, thereby causing damage to the electrical plug 5331.

As shown in fig. 5, the detecting assembly 53 further includes a pin 534, the housing 5332 and the connecting portion 532 have mounting holes matching with each other, and the pin 534 is adapted to pass through the mounting holes of the housing 5332 and the connecting portion 532 simultaneously to fix the connecting portion 532 and the housing 5332.
