Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrophoresis technology for automobile leaf springs, and in particular relates to an electrophoresis conductive connecting device. Background Art
[0002] During the production and processing of automobile leaf springs, it is necessary to perform electrophoresis on the automobile leaf springs. Specifically, an electrophoretic protective layer is formed on the surface of the spring through electrophoresis. The formation of the electrophoretic protective layer can protect the automobile leaf springs, such as increasing the antioxidant properties of the automobile leaf springs, improving the corrosion resistance of the automobile leaf springs, and improving the wear resistance of the automobile leaf springs.
[0003] At present, in the production and processing process, the electrophoresis line conductive device of the leaf spring is usually installed on the guide rail connecting plate using a U-shaped copper gasket. Due to the small stiffness of the U-shaped copper gasket, when the amplitude is too large, the copper gasket cannot fully contact with the fixed conductive copper plate, and the charge cannot be conducted to the hanger, and the electrophoresis quality cannot be guaranteed.
[0004] At the same time, during the electrophoresis process, as the end of the electrophoresis device is constantly in contact with the charged copper plate, friction is generated during the contact process. With long-term friction contact, the end of the electrophoresis device and the charged copper plate are worn out, which in turn causes the gap between the end of the electrophoresis device and the charged copper plate to gradually become too large, and the large gap leads to poor electrical contact. In severe cases, electric sparks are easily generated during the electrophoresis process, and the formation of electric sparks greatly increases the risk of electrophoresis work, such as igniting working equipment.
[0005] Therefore, in the actual working process, in order to ensure the quality of electrophoresis, it is necessary to design a conductive structure with greater rigidity and the ability to automatically adjust the gap. Utility Model Content
[0006] Based on the above background, the purpose of the utility model is to provide an electrophoretic conductive connection device.
[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:
[0008] An electrophoretic conductive connection device comprises a conductive end mechanism, wherein the conductive end mechanism is slidably assembled and connected with a conductive base mechanism;
[0009] The conductive base mechanism comprises a conductive base plate, and a guide tube is fixedly connected to the top of the conductive base plate;
[0010] The conductive end mechanism also includes a conductive end, the conductive end is integrally formed with a sliding column body slidably connected in the guide tube, an upper spring is sleeved on the sliding column body, and two ends of the upper spring are respectively fixedly connected to the bottom of the conductive end and the top of the guide tube;
[0011] The conductive base plate is connected to the track connecting plate through a spring structure.
[0012] Preferably, the guide tube comprises a lower tube portion fixedly connected to the center position of the top of the conductive base plate, and the lower tube portion is integrally formed with a convex tube portion;
[0013] The outer diameter of the convex tube portion is smaller than the outer diameter of the lower tube portion;
[0014] The sliding column is slidably connected in the tube cavity of the convex tube part.
[0015] Preferably, the left and right ends of the conductive base plate are respectively connected to the track connecting plate through spring structure assembly.
[0016] Preferably, the spring structure comprises a screw rod slidably assembled and connected to the conductive base plate;
[0017] The screw rod is threadedly connected to the track connecting plate.
[0018] Preferably, a lower spring is sleeved on the screw rod, the top of the lower spring is fixedly connected to the top position of the conductive base plate, and the bottom of the lower spring is fixedly connected to the top position of the track connecting plate.
[0019] Preferably, the conductive end is equipped with a resilient electrical contact mechanism.
[0020] Preferably, the elastic electrical contact contact mechanism comprises an electrical contact contact;
[0021] The bottom of the electrical contact is fixedly connected with a sliding column protrusion which is slidably connected to the conductive end;
[0022] A plurality of elastic metal plates are fixedly connected to the conductive end, and the elastic metal plates elastically contact the sliding column protrusion.
[0023] Preferably, a plurality of convex seats are fixedly connected to the sliding column convexly, and the upper end of the elastic metal plate abuts against the bottom position of the convex seat.
[0024] Preferably, the lower end of the elastic metal plate is welded to the top position of the conductive terminal.
[0025] The utility model has the following beneficial effects:
[0026] 1. During the working process, the rail connecting plate and the conductive base plate are first connected by a lower spring-screw structure. Therefore, during the working process, the conductive base plate can be kept elastically lifted and lowered in a certain space, thereby ensuring that the conductive end can be elastically contacted with the conductive copper plate.
[0027] 2. The conductive end is assembled in the guide tube through the sliding column and the upper spring structure, so that it can be further abutted against the conductive copper plate by elastic abutment. In this way, during the electrophoresis process, the entire electrophoresis device can be elastically abutted against the conductive copper plate. Under the elastic abutment, the electrical contact is very good. When the conductive copper plate and the conductive end are worn, poor electrical contact or even electric sparks will not occur due to excessive spacing.
[0028] 3. Through the design of the electrical contact contact and the elastic metal plate, during the working process, the operator rotates the electrical contact contact until the convex seat on the electrical contact contact corresponds to the position of the elastic metal plate. At this time, the electrical contact contact is plugged into the conductive end. When the electrophoresis device electrically contacts the conductive copper plate, the electrical contact contact is pressed onto the conductive copper plate. Under the action of the contact pressure, the elastic metal plate bends. After bending, an elastic driving force is generated, which pushes the convex seat, thereby maintaining the electrical contact contact in full electrical contact with the conductive copper plate.

[0039] Example 1
[0040] like Figure 1-5 As shown, an electrophoresis conductive connection device includes a conductive end mechanism 2, and the conductive end mechanism 2 is slidably assembled and connected with a conductive base mechanism. Specifically, the conductive base mechanism includes a conductive base plate 3, and a guide tube 22 is fixedly connected to the top of the conductive base plate 3.
[0041] The conductive terminal mechanism 2 also includes a conductive terminal 21 (the conductive terminal 21 is in direct electrical contact with the conductive copper plate during operation), and the conductive terminal 21 is integrally formed with a sliding column 211 that is slidably connected to the guide tube 22, and an upper spring 221 is sleeved on the sliding column 211, and the two ends of the upper spring 221 are respectively fixedly connected to the bottom of the conductive terminal 21 and the top of the guide tube 22.
[0042] The shape of the guide tube 22 is as follows: the guide tube 22 includes a lower tube portion fixedly connected to the top center position of the conductive base plate 3, and the lower tube portion is integrally formed with a convex tube portion 221; the outer diameter of the convex tube portion 221 is smaller than the outer diameter of the lower tube portion; correspondingly, the sliding column 212 is slidably connected in the tube cavity of the convex tube portion 221.
[0043] The conductive base plate 3 is connected to the track connecting plate 3 through a spring structure. Specifically, the left and right ends of the conductive base plate 3 are respectively connected to the track connecting plate 3 through spring structures. The spring structure includes a screw 24 that is slidably assembled and connected to the conductive base plate 3; the screw 24 is threadedly connected to the track connecting plate 3.
[0044] At the same time, in order to maintain elastic contact, a lower spring 25 is sleeved on the screw rod 24 , the top of the lower spring 25 is fixedly connected to the top position of the conductive base plate 3 , and the bottom of the lower spring 25 is fixedly connected to the top position of the track connecting plate 3 .
[0045] During the working process, first, the rail connecting plate 3 and the conductive base plate 3 are connected by the lower spring 25-screw 24 structure. Therefore, during the working process, the conductive base plate 3 can be kept elastically lifted and lowered in a certain space, thereby ensuring that the conductive end 21 can be in elastic contact with the conductive copper plate 1.
[0046] Similarly, since the conductive end 21 is assembled in the guide tube 22 through the sliding column 212 and the upper spring 221 structure, it is further elastically abutted against the conductive copper plate 1 in this way. In this way, during the electrophoresis process, the entire electrophoresis device can be elastically abutted against the conductive copper plate 1. Under the elastic abutment, the electrical contact is very good. When the conductive copper plate 1 and the conductive end 21 are worn, poor electrical contact or even electric sparks will not occur due to excessive spacing.
[0047] Example 2
[0048] like Figure 1-5 As shown, based on the structure of Example 1, in order to further increase the ability of the conductive terminal 21 to elastically contact and press on the conductive copper plate 1, the conductive terminal 21 is equipped with an elastic electrical contact mechanism 4. Specifically, the elastic electrical contact mechanism 4 includes an electrical contact 41 (the transverse cross-section of the electrical contact 41 is circular).
[0049] At the same time, the bottom of the electrical contact 41 is fixedly connected with a sliding column convex 411 that is slidably connected to the conductive terminal 21 (correspondingly, an adaptive sliding groove is provided on the conductive terminal 21). In addition, to achieve elastic resistance, a plurality of elastic metal plates 43 are fixedly connected to the conductive terminal 21 (the elastic metal plates 43 are made of copper alloy material with excellent electrical conductivity and elasticity, and the lower end of the elastic metal plates 43 is welded to the top of the conductive terminal 21), and the elastic metal plates 43 elastically resist against the sliding column convex 411.
[0050] Correspondingly, a plurality of bosses 42 are fixedly connected to the sliding column boss 411 , and the upper end of the elastic metal plate 43 abuts against the bottom position of the boss 42 .
[0051] During the operation, the operator rotates the electrical contact contact 41 until the protrusion 42 on the electrical contact contact 41 corresponds to the position of the elastic metal plate 43. At this time, the electrical contact contact 41 is plugged into the conductive terminal 21. When the electrophoresis device electrically contacts the conductive copper plate 1, the electrical contact contact 41 is pressed onto the conductive copper plate 1. Under the action of the contact pressure, the elastic metal plate 43 bends. After bending, an elastic driving force is generated, which pushes the protrusion 42, thereby achieving the electrical contact contact 41 being kept in full electrical contact with the conductive copper plate 1 in this way.
[0052] When it is not necessary to use the electrical contact 41 to elastically abut against the conductive copper plate 1, the conductive copper plate 1 is rotated to stagger the positions of the protrusion 42 and the elastic metal plate 43, and at this time, the free state abutment is maintained.
[0053] The above method further adopts an elastic structure design to elastically press the additionally designed electrical contact contact 41 against the conductive copper plate 1 to solve the problem that when the distance between the conductive end 21 and the conductive copper plate 1 is too large during operation, the electrical contact contact 41 with an additional elastic structure design is used to elastically contact the conductive copper plate 1 again.
[0054] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
