Description

Technical Field

[0002] There are many electrical connections inside the car, and some connectors are often used, and these connectors need to be tested for polarity, such as Fig. 9 The connector shown has an overall cylindrical structure and terminals are provided at the bottom. During polarity detection, the connector needs to be plugged in and out. At present, most polarity detections are for connectors with small size, and the plug-in detection is performed after the connectors are individually fixed. When a large number of connectors need to be detected, the efficiency of individual detection is low, and the efficiency can be improved by cooperating with automated equipment. However, since the product is a cylindrical part, especially for turntable-type detection equipment, it is difficult to ensure that the cylindrical positioning carrier is facing the detection plug during assembly. Therefore, plug-in errors often occur during operation, resulting in broken pins. In addition, for some products of slightly different sizes, the terminal part at the bottom of the product extends into the carrier at different lengths, and the carrier needs to be replaced, which is cumbersome.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figure 1 , Figure 2 As shown, the present invention proposes a connector plugging device for polarity testing equipment, comprising

[0030] The turntable 1 has a plurality of bearing seats 2 arranged on the circumference thereof. The bearing seats 2 are used to position the plug 15 to be tested. A reducer is connected to the lower part of the turntable 1 to drive the turntable 1 to rotate indexingly. The bearing seats 2 are evenly distributed on the circumference of the turntable 1. Specifically: Figure 7 As shown, the bearing seat 2 includes a circular carrier plate, a lower protrusion 25 is provided at the lower part of the circular carrier plate 24, a hole is provided on the turntable 1, the lower protrusion 25 passes through the hole and extends to the lower part of the disc, a placement hole 27 is provided in the center of the circular carrier plate 24, a groove 28 is provided on the side wall, and a square support edge 26 is provided at the bottom of the lower protrusion 25. The square support edge can position the edge of the product placed therein to prevent it from rotating on the carrier plate, and the joint to be tested is facing the outside of the groove.

[0031] There are also corresponding square grooves on the carrier. The detection position of the product is the main joint. There is a point on the cylindrical side wall above the main joint that needs to be detected, so a specially designed square groove is used to facilitate docking.

[0032] like Figure 2 As shown, at least one group of clamping and plug-in components 3 is arranged on the side of the turntable 1. In order to improve the efficiency, multiple groups can be arranged. One group of clamping and plug-in components 3 corresponds to one group of floating plug-in components 6. The clamping and plug-in components 3 are located on the side of the turntable 1. The clamping and plug-in components 3 include a frame 4. The frame 4 is provided with a pressing component 5 and a lifting floating component. The pressing component 5 is located above the supporting seat 2. The pressing component 5 uses a cylinder, and a pressure block is connected to the output end of the cylinder. The pressure block is pressed down on the top of the product to be tested. First, the product on the carrier is positioned. Due to the characteristics of the product, a pressure block is set to press the top of the product with a small area for better stability.

[0033] Then the product is connected to the side plug 15 for testing. The terminal of the plug 15 is connected to an external testing device (not shown in the figure). In order to ensure the accuracy of the plug 15 connecting to the product, a floating plug assembly 6 is specially provided.

[0034] like Figure 3 to Figure 6 As shown, the floating plug-in assembly 6 includes a base 7, a pressure plate 8 and an insert 9 located on the pressure plate 8, the base 7 and the pressure plate 8 are connected by a plurality of guide pillars 10, a rotating cam 12 is provided on the base 7, a fixed cam 11 is provided on the pressure plate 8, the fixed cam 11 is pressed on the rotating cam 12, and the fixed cam 11 and the rotating cam 12 are provided with continuous protrusions arranged in an annular manner on the opposite surfaces, a toggle rod 13 is connected to the rotating cam 12, the protrusions of the fixed cam 11 and the rotating cam 12 are both arranged on the radial surface, and the protrusions are all arranged continuously and gently, and the upper rotating cam 12 When the raised position coincides with the lower fixed cam 11, the upper fixed cam 11 and the upper base 7 and other components are lifted up, and when the raised and non-raised positions are pressed together, the upper fixed cam 11 and the base 7 and other components are lowered to a certain height, thereby ensuring that the plug-in part 9 can be adjusted a certain distance in the height direction to solve the problem that when there are slight differences in product size, the downward length of the terminal at the bottom of the product is small, resulting in the product not being in place. The height can be adjusted by adjusting the lower rotating cam 12, and the toggle rod 13 connected to the rotating cam 12 can be manually adjusted or connected to a power component such as a cylinder or an oil cylinder for pull adjustment.

[0035] like Figure 5As shown, the plug-in component 9 includes a pushing component 14, which is a cylinder. At least one group of plugs 15 are connected to the output end of the pushing component 14. The plug 15 includes multiple groups of pins inside for conducting and connecting with the connector. After the position is adjusted in the vertical direction, there may be errors in the horizontal direction, which makes it difficult to plug in. Therefore, a horizontal floating component is connected to the lower part of the plug 15. The horizontal floating component is used to adjust the plug-in position between the plug 15 and the product to be tested. Specifically, the horizontal floating component includes a fixed plate 16, and a trumpet-shaped slot 17 is provided on the fixed plate 16. A floating block 18 is rotatably connected in the trumpet-shaped slot 17. Elastic members 19 are provided on both sides of the floating block 18 and the trumpet-shaped slot 17. The elastic member 1 9 can be made of spring or soft silicone. The plug 15 is fixedly connected with the floating block 18 and points to the bearing seat 2. The inner angle of the end of the trumpet-shaped slot 17 is an arc angle. The end of the floating block 18 is a chamfer 20. The floating block 18 is connected to the fixed block through a rotating pin 21. The floating block 18 is connected to the fixed block through elastic members 19 arranged on both sides. When plugging in, since the mouth 22 of the plug 15 is arc-shaped, when the push assembly 14 pushes the plug 15 to the product, when the plug 15 is plugged in, the arc-shaped mouth 22 can guide the plugging position and adjust it through the spring. In addition, a second pin is fixedly connected above the floating block 18, which can follow the floating angle of the floating block 18 to facilitate docking with the terminal on the cylindrical shell. The device can simultaneously realize the position adjustment in the horizontal direction and the vertical direction, which greatly improves the stability of the detection of plugging.
