Description

Technical Field

[0001] This application relates to the technical field of connector detection, for example, it relates to an automotive connector detection device. Background Art

[0002] In the related art (Publication No.: CN220670913U), a strength detector for a lock device of a non-assisted automotive connector is disclosed, which includes a detector base. An adjusting mechanism is installed on the left side of the top end of the detector base. A plugging and unplugging mechanism is installed on the right side of the top end of the detector base. The plugging and unplugging mechanism includes a turntable, a sleeve, a plug rod, a sliding seat, a sliding rail, a button, a spring, a clamping block and a diamond-shaped block. Clamping mechanisms are installed on the top ends of both the adjusting mechanism and the plugging and unplugging mechanism.

[0003] In the process of implementing the above embodiments, it is found that at least the following problems exist in the related art:

[0004] For this strength detector for a lock device of a non-assisted automotive connector, through the cooperation of the button, the spring, the clamping block and the diamond-shaped block, the extending length of the plug rod from the sleeve can be adjusted, and then the movement position of the sliding seat relative to the sliding rail for one reciprocating movement can be changed, so as to detect connectors with different plugging and unplugging depths. However, limited by the distance between two adjacent card slots, the extending length of the plug rod from the sleeve changes stepwise as an integer multiple of the distance between two adjacent card slots. Therefore, it can only be used to detect connectors with multiple plugging and unplugging depths, and cannot be used for the detection work of connectors with different plugging and unplugging depths.

[0036] Combined with Figures 1 to 4As shown in the figure, an automotive connector detection device provided by an embodiment of the present disclosure includes a bracket 10, a third support plate 20, a fourth support plate 30, a motor 40, a turntable 50, a support 60, a spherical plain bearing 70, a connecting rod for spherical plain bearing 80, a tension and compression sensor 90, and a fixture 100. The bracket 10 includes a first support plate 11, a second support plate 12, and a first optical axis 13. The first optical axis 13 is installed between the opposite surfaces of the first support plate 11 and the second support plate 12 to determine the relative positions of the first support plate 11 and the second support plate 12. Along the height direction of the first optical axis 13, the first support plate 11 is located above the second support plate 12. The third support plate 20 is slidably sleeved on the first optical axis 13 and is located between the opposite surfaces of the first support plate 11 and the second support plate 12, and can slide along the first optical axis 13. The fourth support plate 30 is slidably sleeved on the first optical axis 13 and is located between the opposite surfaces of the second support plate 12 and the third support plate 20, and can also slide along the first optical axis 13. The motor 40 is installed on the bottom surface of the first support plate 11 to provide driving force to achieve rotational motion. The turntable 50 is installed on the rotating end of the motor 40 and makes a rotational motion under the drive of the motor 40. The support 60 is installed on the top surface of the third support plate 20 to drive the third support plate 20 to move. The spherical plain bearings 70 are respectively rotatably installed on the turntable 50 and the support 60, and can respectively rotate relative to the turntable 50 and the support 60.

[0037] For an automotive connector detection device provided by an embodiment of the present disclosure, after the connector plug and the connector socket are respectively clamped and fixed by the two fixtures 100, the motor 40 is controlled to work, which can drive the disc to make a rotational motion. Then, under the pulling or pushing of the connecting rod for spherical plain bearing 80, the support 60 can drive the third support plate 20 to reciprocally slide along the first optical axis 13. Thereby, the distance between the two fixtures 100 is changed, and the connector plug and the connector socket are repeatedly plugged and unplugged. During the unplugging process, the tension and compression sensor 90 can detect the magnitude of the unplugging force in real time. During the insertion process, the tension and compression sensor 90 can detect the magnitude of the insertion force in real time, thus completing the detection work. Moreover, by rotating the connecting rod for spherical plain bearing 80, the protruding length from the two spherical plain bearings 70 can be changed, and the protruding length of the connecting rod for spherical plain bearing from the two spherical plain bearings 70 changes linearly. Therefore, it can be applied to the detection work of connectors with different plugging and unplugging depths.
