Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steering systems, in particular to a planar bearing anti-escape structure of an electric signal transmission plug for assembly line production. Background Art
[0002] With the change of automobile electronics and intelligence, a large number of electronic chip circuits are used in automobile parts for assisted driving. Software transmission and import and power-on testing are required in automobile production and assembly, so signal transmission plugs are increasingly used in automobile production.
[0003] This type of plug consists of a single socket or multiple sockets. All sockets need to have a certain degree of floatation to accommodate errors in manufacturing and clamping. Most plugs usually use a mechanism similar to a plane bearing to ensure a certain degree of floatation. However, in daily use, it is found that when the plug has a large offset, the steel ball holding the nylon will have a large offset from the upper and lower planes and cannot be restored, causing the steel ball to escape, reducing the floating performance of the plug, and ultimately causing the plug to collide with parts and become scrapped. Summary of the invention
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a planar bearing anti-escape structure for an electrical signal transmission plug for assembly line production. The structure adopts a simple design for easy adjustment and has little effect on the size of the plug. During use, the structure can prevent the steel ball from gradually shifting to maintain the nylon sheet, which eventually causes the steel ball to fall off, resulting in a decrease in the floating effect of the plug and causing collision with parts to produce defective products.
[0005] In order to achieve the above-mentioned purpose, a planar bearing anti-escape structure of an electrical signal transmission plug for assembly line production is designed, including a floating mechanism, characterized in that: the floating mechanism is composed of an upper part of the floating mechanism and a lower part of the floating mechanism, and the upper part of the floating mechanism is fixedly connected to a limiting bolt; the bottom surface of the upper part of the floating mechanism is an upper plane of the floating mechanism, the top surface of the lower part of the floating mechanism is a lower plane of the floating mechanism, and a steel ball retaining nylon sheet is provided between the upper plane of the floating mechanism and the lower plane of the floating mechanism; tension springs are respectively provided on the left and right sides of the limiting bolt, one end of the tension spring is connected to the upper part of the floating mechanism, and the other end of the tension spring passes through the steel ball retaining nylon sheet and is connected to the lower part of the floating mechanism.
[0006] A plurality of steel balls are arranged on the steel ball retaining nylon sheet located between the upper plane of the floating mechanism and the lower plane of the floating mechanism.
[0007] The rod of the limiting bolt is a cylindrical structure, and the upper outer edge of the limiting bolt is provided with a thread; the upper part of the limiting bolt is connected to the upper part of the floating mechanism through a thread.
[0008] One end of the tension spring is connected to the upper part of the floating mechanism, the other end of the tension spring is connected to the lower part of the floating mechanism, and the other end of the tension spring is positioned by a positioning pin.
[0009] There are at least two tension springs.
[0010] Compared with the prior art, the utility model provides a planar bearing anti-escape structure for an electrical signal transmission plug for assembly line production. It adopts a simple design for easy adjustment and has little effect on the size of the plug. During use, it can prevent the steel ball from gradually offsetting the nylon sheet, which eventually causes the steel ball to fall off, resulting in a decrease in the floating effect of the plug and causing collision with parts to produce defective products.

[0015] The utility model is further described below with reference to the accompanying drawings.
[0016] Figure 1 This is the overall schematic diagram of the plug structure. Figure 2 The internal structure of the plug. Figure 3 This is a cross-sectional view of the plug, in which the position of the limiting bolt 3 in the floating mechanism can be seen. Figure 4 It is a partially enlarged schematic diagram, and it can be seen that a limit bolt 3 is installed in the middle of the plane floating mechanism. The limit bolt 3 can limit the steel ball retaining nylon sheet 4 to a certain extent. Cooperating with the tensioning spring 5 of the plane floating mechanism, it can reduce the excessive deviation of the steel ball retaining nylon sheet, thereby causing the sliding steel ball to fall off and affecting the smoothness of the plane floating mechanism.
[0017] Specific as Figure 4As shown, the floating mechanism consists of a floating mechanism upper part 1 and a floating mechanism lower part 2, and the floating mechanism upper part 1 is fixedly connected to a limiting bolt 3; the bottom surface of the floating mechanism upper part 1 is a floating mechanism upper plane 1-1, the top surface of the floating mechanism lower part 2 is a floating mechanism lower plane 2-1, and a steel ball retaining nylon sheet 4 is provided between the floating mechanism upper plane 1-1 and the floating mechanism lower plane 2-1; tension springs 5 are provided on the left and right sides of the limiting bolt 3, one end of the tension spring 5 is connected to the floating mechanism upper part 1, and the other end of the tension spring 5 passes through the steel ball retaining nylon sheet 4 and is connected to the floating mechanism lower part 2.
[0018] A plurality of steel balls are arranged on the steel ball retaining nylon sheet 4 located between the upper plane 1 - 1 of the floating mechanism and the lower plane 2 - 1 of the floating mechanism.
[0019] The rod of the limiting bolt 3 is a cylindrical structure, and the upper outer edge of the limiting bolt 3 is provided with a thread; the upper part of the limiting bolt 3 is connected to the upper part 1 of the floating mechanism through a thread.
[0020] One end of the tension spring 5 is connected to the upper part 1 of the floating mechanism, and the other end of the tension spring 5 is connected to the lower part 2 of the floating mechanism, and the other end of the tension spring 5 is positioned by a positioning pin 6.
[0021] At least two tension springs 5 are provided.
[0022] like Figure 4 As shown, the floating mechanism comprises an upper floating mechanism portion 1, a lower floating mechanism portion 2, a steel ball in the middle which holds a nylon sheet 4 and the steel ball, and the upper and lower surfaces are pulled by a tension spring 5 to ensure that the steel ball in the middle is pressed between the upper plane 1-1 of the floating mechanism and the lower plane 2-1 of the floating mechanism, so that the upper and lower surfaces can float and slide.
[0023] A limit bolt 3 is screwed into the upper part 1 of the floating mechanism. The rod of the limit bolt 3 is a cylindrical part (without thread), and the limit bolt 3 passes through the upper and lower planes and the steel ball retaining nylon sheet 4. A suitable gap (maximum floating requirement) is maintained between the cylinder and the steel ball retaining nylon sheet 4, so that the steel ball retaining nylon sheet 4 will be limited by the middle limit bolt 3 and two tension springs 5 to ensure that the steel ball retaining nylon sheet 4 will not deviate too much and cause the steel ball to fall off.
[0024] The utility model adopts a simple design that is easy to adjust and has little effect on the size of the plug. During use, it can prevent the steel ball from gradually shifting and holding the nylon sheet, which eventually causes the steel ball to fall off, causing the floating effect of the plug to decrease, resulting in collision with parts and producing defective products. It can effectively increase the life of the floating mechanism of the plug, increase the service life of the plug, reduce product scrapping, and reduce the cost of use.
