Description

Technical Field

[0001] The present invention relates to the field of electrical connectors, and more particularly to an open crown spring socket structure. Background Art

[0002] The crown spring jack assembly is an important component, which is usually used to connect two mechanical parts and provide the necessary elasticity and support. The structure and performance of the crown spring jack assembly directly affect the working efficiency and reliability of mechanical equipment. In harsh working environments, such as humidity, corrosive gases and dust, the crown spring jack assembly is easily corroded by mud and salt water, resulting in its performance degradation or even failure. Therefore, preventing the corrosion of the crown spring jack assembly by mud and salt water is an important technical challenge.

[0003] Existing crown spring jack assemblies usually adopt a closed design to prevent mud and salt water from entering the jack. However, this design has the following problems. First, the closed design increases the size and weight of the jack, which is a disadvantage for some applications that require compact design and high precision. Second, the closed design increases manufacturing costs because more materials and more complex processing are required. Finally, the closed design may affect the heat dissipation performance of the jack, causing the jack to overheat, thereby affecting its performance and life. Summary of the invention

[0004] The present invention overcomes the deficiency of the prior art in preventing external pollution and erosion, and provides an open crown spring socket structure, in the hope of solving the problems existing in the prior art.

[0005] In order to solve the above technical problems, one embodiment of the present invention adopts the following technical solution:

[0006] An open crown spring jack structure, comprising: a crown spring, an outer cylinder;

[0007] The front end of the outer tube is provided with a crown spring mounting hole, a liquid guide groove is provided in the crown spring mounting hole, and a liquid leakage hole is provided at the bottom of the liquid guide groove;

[0008] The leakage hole communicates the inside and outside of the crown spring installation hole;

[0009] The crown spring is installed in the crown spring installation hole.

[0010] When muddy salt water or other fluid impurities enter the crown spring installation hole of the outer cylinder, the muddy salt water will gather in the liquid guide groove and eventually flow out from the leakage hole at the bottom of the liquid guide groove. When the crown spring socket is connected, the heat generated by the current can also be exchanged with the outside world through the leakage hole, thereby improving the heat dissipation effect.

[0011] A further technical solution is that the liquid guide groove is arranged on the side and bottom of the crown spring installation hole;

[0012] A liquid leakage hole is arranged at the bottom of each liquid guiding groove.

[0013] Liquid guide grooves and leakage holes are arranged on the side and bottom of the crown spring mounting hole. On the one hand, fluid impurities entering the crown spring socket can be discharged through leakage holes at different positions. On the other hand, it can also balance the air pressure in the crown spring mounting hole and facilitate the outflow of fluid.

[0014] A further technical solution is that a reed quick-change removal hole is provided on the outer cylinder;

[0015] The crown spring is formed by rolling a reed sheet, and the reed sheet has a certain curvature when unfolded, and the crown spring formed after rolling is in an hourglass shape.

[0016] When the crown spring is in use, it may fail due to corrosion and wear. In the prior art, when replacing the crown spring, it is usually necessary to first disassemble it and then replace it. The present application rolls the crown spring from the reed sheet, and when the crown spring needs to be replaced, the sheet-shaped crown spring can be pulled out from the reed sheet quick-change removal hole on the outer cylinder, and then a new reed sheet is put into the reed sheet quick-change removal hole to finally complete the installation.

[0017] A further technical solution is that the reed is divided into a curved portion and a flat portion;

[0018] The length of the central axis of the arc part is shorter than the length of the two sides of the arc part, and the cross section has a certain arc;

[0019] The flat parts are arranged on both sides of the curved part, and the flat parts have no curvature after being unfolded.

[0020] The curved portion of the reed can form an hourglass structure with two thick parts and a thin middle part after being rolled up, thereby realizing the main function of the crown spring, and the flat portion of the reed is mainly used for installation and fixation in the crown spring installation hole.

[0021] A further technical solution is that a honeycomb hole structure is provided on the arc portion;

[0022] The flat part is provided with convex points.

[0023] By designing the traditional strip crown spring into a honeycomb appearance, the contact area of ​​the crown spring can be significantly increased. Due to the larger contact area, the current carrying capacity can be increased, thereby improving the performance of the device, and improving stability and preventing deformation caused by vibration in the future.

[0024] Providing convex points on the flat part of the crown spring can further enhance the contact stability. The convex points can increase the friction between the crown spring and the contact surface, prevent sliding under stress, and thus improve the reliability and service life of the equipment.

[0025] A further technical solution is that the head and tail of the flattened portion are provided with anti-stack dislocation devices;

[0026] The anti-stack dislocation shapes of the head and tail are complementary.

[0027] Reeds need to be stacked during transportation and storage, and the misalignment of the stacking is mainly used to prevent the reeds from deforming due to misalignment between the springs during transportation.

[0028] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention effectively prevents mud and salt water from corroding the socket through the open crown spring socket structure, thereby improving the reliability and service life of the socket; at the same time, the open design enables the socket to better exchange heat with the external environment, thereby improving the heat dissipation performance. Furthermore, the present invention also discloses a honeycomb-type sheet crown spring, whose unique structure can effectively prevent mud and salt water and other fluids from entering the socket, and improves the contact effect and the convenience of replacing the crown spring.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] An open crown spring 1 socket structure, see Figure 1 , Figure 2 , including: crown spring 1, outer cylinder 2;

[0037] The front end of the outer tube 2 is provided with a crown spring 1 mounting hole, a liquid guide groove 21 is provided in the crown spring 1 mounting hole, and a liquid leakage hole 22 is provided at the bottom of the liquid guide groove 21;

[0038] In this embodiment, the liquid guide groove 21 is arranged on the side and bottom of the crown spring 1 mounting hole. Specifically, two liquid guide grooves 21 are arranged on the side of the crown spring 1 mounting hole, and a liquid guide groove 21 is arranged at the bottom of the crown spring 1 mounting hole. Each liquid guide groove 21 is arranged at the bottom with a liquid leakage hole 22.

[0039] The leakage hole 22 communicates the inside and outside of the installation hole of the crown spring 1;

[0040] The crown spring 1 is installed in the crown spring 1 installation hole.

[0041] The outer cylinder 2 is provided with a quick-change and removal hole for the reed 12; in the present embodiment, the quick-change and removal hole for the reed 12 is located at the top of the mounting hole of the crown spring 1 and is a continuous long strip-shaped hole.

[0042] The crown spring 1 is wound from a spring sheet 12, see Figure 3-Figure 5 The reed leaf 12 has a certain curvature when unfolded, and the crown spring 1 formed after winding is in the shape of an hourglass.

[0043] In this embodiment, the reed 12 is divided into a curved portion 13 and a flat portion 14;

[0044] The length of the central axis of the arc part 13 is shorter than the length of the two sides of the arc part 13, and the cross section has a certain curvature. A honeycomb hole structure is provided on the arc part 13; in this embodiment, the honeycomb hole is a regular hexagon.

[0045] The flat portion 14 is arranged at both sides of the curved portion 13 . The flat portion 14 has no curvature after being unfolded, and convex points are arranged on the flat portion 14 .

[0046] The head and tail of the flattened portion 14 are provided with anti-stack dislocation 15;

[0047] The anti-stack dislocation 15 of the head and tail are complementary in shape.

[0048] When in use, firstly, the reed sheet 12 is rolled into the crown spring 1, and the crown spring 1 is installed in the crown spring 1 installation hole at the front end of the outer tube 2. At this time, the flat part 14 of the reed sheet 12 is rolled into a cylinder and contacts with the crown spring 1 installation hole. There are convex points on the flat part 14, which contact with the crown spring 1 installation hole, increasing the friction between the crown spring 1 and the contact surface to prevent sliding under force.

[0049] If muddy salt water or other fluid impurities enter the installation hole of the crown spring 1 of the outer tube 2, the muddy salt water will gather in the liquid guide groove 21 and effectively guide the muddy salt water to be discharged from the socket through the leakage hole 22 to prevent its accumulation; and when the socket of the crown spring 1 is connected, the heat generated by the current can also be exchanged with the outside world through the leakage hole 22, thereby improving the heat dissipation effect.

[0050] As the crown spring 1 is used, it may fail due to corrosion and wear. When replacing, the reed 12 can be squeezed from the quick-change removal hole of the reed 12, and the squeezed crown spring 1 can be pulled out from the quick-change removal hole of the reed 12 on the outer tube 2, and then a new reed 12 can be put into the quick-change removal hole of the reed 12. Since the reed 12 itself has elasticity, it can be formed in the installation hole of the crown spring 1. If the shape needs to be adjusted, it can also be adjusted through the quick-change removal hole of the reed 12 with a tool, and finally the replacement and installation are completed.

[0051] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, it should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in the present application. More specifically, within the scope disclosed in the present application, multiple variations and improvements can be made to the components and / or layout of the subject combination layout. In addition to the variations and improvements made to the components and / or layout, other uses will also be apparent to those skilled in the art.
