Description

Technical Field

[0001] The present application relates to the technical field of connection devices, and in particular to a spring clip that is easy to plug and unplug and has stable connections with multiple contact surfaces. Background Art

[0002] Shrapnel, also known as spring sheet, is a metal sheet element with good elasticity and fatigue resistance. It is usually made of stainless steel, elastic alloy steel and other materials, with high hardness and wear resistance. The main feature of the shrapnel is that it can produce a certain elastic deformation under the action of external force, and can quickly return to its original shape when the external force is removed.

[0003] In the field of machinery and vehicles, springs are often used in buffering and shockproof devices and relay delay devices. They have various shapes and structural types, including rectangular, trapezoidal, triangular and step-shaped, and structural types include straight leaf springs and curved leaf springs. In the field of electronics, springs are widely used as electronic components in various electronic products and equipment, such as communication equipment, computers, home appliances, and automobiles.

[0004] In the prior art, in order to make the plugging and unplugging of the spring clip more convenient, the contact surface of the spring clip is usually reduced. However, reducing the contact surface will lead to poor stability during connection. Therefore, a spring clip with easy plugging and unplugging and stable connection with multiple contact surfaces is needed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present application is to provide a spring clip that is easy to plug and unplug and has stable connections on multiple contact surfaces to solve the above technical problems.

[0006] The above-mentioned purpose of the present application is achieved through the following technical scheme: a spring piece that is easy to plug and unplug and has stable multi-contact surface connections, including a spring piece body, the spring piece body including a plate-like base and a limiting portion, the plate-like base and the limiting portion are integrally formed, the connecting end of the plate-like base and the limiting portion is curved, a bending portion is fixedly provided on the end of the limiting portion, and a contact strip is fixedly provided on the end of the plate-like base away from the limiting portion.

[0007] By adopting the above technical solution, when the spring sheet body is inserted into the device, by pressing the two sides of the plate-like base and the limiting part, after the spring sheet body is inserted into the device, the pressing is stopped, and the bending part on the limiting part and the contact strip on the plate-like base will be stuck in the device, thereby ensuring its stability. When removing it, the two sides of the plate-like base and the limiting part will also be pressed. Since the bending part on the limiting part is arc-shaped, the friction with the device will be reduced, thereby making it more convenient to remove it.

[0008] Furthermore, two ends of the contact strip are in arc shape.

[0009] By adopting the above technical solution, when inserting, since both sides of the contact strip are curved, it does not require much effort to slide in, and when removing, the curved sides can also prevent getting stuck.

[0010] Furthermore, a straight insertion portion is fixedly provided at the end of the plate-like base, and both sides of the straight insertion portion are arc-shaped.

[0011] By adopting the above technical solution, during insertion, since the end is arc-shaped, it can fit more closely with the slot in the device, thereby playing a guiding role.

[0012] Furthermore, vertical plates fixedly connected to the plate-like base are arranged on both sides of the plate-like base, and a limiting horizontal plate is fixedly arranged on one end of the vertical plate away from the plate-like base.

[0013] By adopting the above technical solution, since the connection between the plate-like base and the limiting part is bent, in order to prevent the bending angle from being too large, which would require a lot of effort during the plug-in work, the bending angle can be limited by setting the vertical plate and the horizontal plate, thereby solving this technical problem.

[0014] Furthermore, a first arc portion is provided on one end of the plate-like base away from the vertical plate, and the first arc portion is concave inwardly toward the limiting portion.

[0015] By adopting the above technical solution, when removing, it is necessary to press the plate-like base and the limiting part first, and then pull it out. If the two sides of the shrapnel body are smooth, there will be no fulcrum for removal. The setting of the first arc portion will solve this technical problem. Put your hand into the first arc portion, and then press the plate-like base and the limiting part. The fingers will have a fulcrum to better remove the shrapnel body.

[0016] Furthermore, a contact pad is fixedly provided on the outer side of the first arc portion.

[0017] By adopting the above technical solution, considering that the hands of the staff may come into contact with other oily substances during removal, and the first arc portion of the spring body is smoothly arranged, which is not convenient for removal, the contact pad can increase the friction with the hand and better facilitate the removal work.

[0018] Furthermore, a second arc portion opened on the plate-shaped base is provided on one end of the first arc portion, and the second arc portion is concave in a direction away from the limiting portion.

[0019] By adopting the above technical solution, after the spring body is inserted, the second arc portion will become an additional contact surface, thereby increasing internal friction and improving stability.

[0020] Furthermore, the spring body is made of stainless steel.

[0021] By adopting the above technical solution, the stainless steel spring has good elasticity and corrosion resistance, and is suitable for scenes that need to withstand large deformation and repeated use. In addition, its high elastic limit, fatigue limit and impact toughness also make it perform well in a variety of applications.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When inserting the spring sheet body into the device, press both sides of the plate-like base and the limiting part. After the spring sheet body is inserted into the device, cancel the pressing, and the bending part on the limiting part and the contact strip on the plate-like base will be stuck in the device to ensure its stability. When removing it, press both sides of the plate-like base and the limiting part. Since the bending part on the limiting part is arc-shaped, it will reduce the friction with the device, making it more convenient to remove.

[0024] 2. Put your fingers into the first arc portion, and then press the plate-shaped base and the limit portion. Your fingers will have a force point to better remove the main body of the shrapnel. A contact pad is fixedly provided on the outside of the first arc portion. Considering that when removing the shrapnel, the hands of the staff may come into contact with other oily substances, and the main body of the shrapnel is a smooth first arc portion, which is not convenient for removal. Therefore, the contact pad can increase the friction with the hand and facilitate the removal work.

[0025] 3. A straight insertion portion is fixedly provided at the end of the plate-like base, and both sides of the straight insertion portion are arc-shaped. When inserting, since the end is arc-shaped, it can fit more closely with the groove in the device, thereby playing a guiding role. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Example, see Figure 1 as well as Figure 2A spring sheet with convenient plugging and unplugging and stable multi-contact surface connection includes a spring sheet body 1, the spring sheet body 1 includes a plate-like base 102 and a limiting portion 101, the plate-like base 102 and the limiting portion 101 are integrally formed, the connecting end of the plate-like base 102 and the limiting portion 101 is curved, a bending portion 103 is fixedly provided at the end of the limiting portion 101, and a contact strip 3 is fixedly provided at one end of the plate-like base 102 away from the limiting portion 101. When the spring sheet body 1 is inserted into the device, by pressing both sides of the plate-like base 102 and the limiting portion 101, the spring sheet body 1 is inserted into the device and then the spring sheet body 1 is removed. By pressing, the bent portion on the limiting portion 101 and the contact strip 3 on the plate-like base 102 will be stuck in the device to ensure its stability. When pulling out, the plate-like base 102 and both sides of the limiting portion 101 will also be pressed. Since the bent portion on the limiting portion 101 is arc-shaped, the friction with the device will be reduced, making it more convenient to pull out. At the same time, the two ends of the contact strip 3 are in an arc shape. When inserting, since the two sides of the contact strip 3 are arc-shaped, it does not take too much effort to slide in. When pulling out, the arc-shaped side can also prevent it from getting stuck.

[0031] In this embodiment, a straight insertion portion 302 is fixedly provided at the end of the plate-like base 102, and both sides of the straight insertion portion 302 are arc-shaped. When inserting, since the end is arc-shaped, it can fit more closely with the groove in the device, thereby playing a guiding role.

[0032] In this embodiment, vertical plates 201 fixedly connected to the plate-like base 102 are provided on both sides, and a limiting horizontal plate 202 is fixedly provided at one end of the vertical plate 201 away from the plate-like base 102. Since the connection between the plate-like base 102 and the limiting portion 101 is bent, in order to prevent the bending angle from being too large, which would require a lot of effort during the plug-in work, the bending angle can be limited by setting the vertical plate 201 and the horizontal plate, thereby solving this technical problem.

[0033] In this embodiment, a first arc portion 203 is provided on the end of the plate-like base 102 away from the vertical plate 201, and the first arc portion 203 is concave toward the direction of the limiting portion 101. When pulling out, it is necessary to press the plate-like base 102 and the limiting portion 101 first, and then pull it out. If both sides of the spring sheet body 1 are smooth, there will be no fulcrum for pulling out. The setting of the first arc portion 203 will solve this technical problem. Put your fingers into the first arc portion 203, and then press the plate-like base 102 and the limiting portion 101. The fingers will have a fulcrum to better pull out the spring sheet body 1. A contact pad 301 is fixedly provided on the outside of the first arc portion 203. Considering that when pulling out, the staff's hands may come into contact with other oily substances, and the first arc portion 203 with a smooth setting of the spring sheet body 1 is not convenient for pulling out, the contact pad 301 can increase the friction with the hand and better facilitate the pulling out work.

[0034] In this embodiment, a second arc portion 204 is provided on one end of the first arc portion 203 and is provided on the plate-like base portion 102. The second arc portion 204 is concave in the direction away from the limiting portion 101. After the spring body 1 is inserted, the second arc portion 204 will become an additional contact surface to increase internal friction and improve stability. The spring body 1 is made of stainless steel. The stainless steel spring has good elasticity and corrosion resistance and is suitable for scenes that need to withstand large deformation and repeated use. In addition, its high elastic limit, fatigue limit and impact toughness also make it perform well in a variety of applications.

[0035] Specific implementation process;

[0036] Before inserting the spring sheet body 1 into the device, align the spring sheet body 1 with the slot of the device, and insert the spring sheet body 1 into the device by pressing the plate-like base 102 and the two sides of the limiting part 101. Then, cancel the pressing, and the bending part on the limiting part 101 and the contact strip 3 on the plate-like base 102 will be stuck in the device, thereby ensuring its stability. When removing, the plate-like base 102 and the two sides of the limiting part 101 will also be pressed. Since the bending part on the limiting part 101 is arc-shaped, the friction with the device will be reduced, thereby making it more convenient to remove. At the same time, the two ends of the contact strip 3 are in an arc shape. When inserting, since the two sides of the contact strip 3 are arc-shaped, it does not require too much effort to slide in. When removing, the arc-shaped side can also prevent it from getting stuck.

[0037] The straight insertion portion 302 can play a guiding role during insertion. The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
