Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and particularly relates to an electrode spring and an endoscope. BACKGROUND

[0002] Generally, the electrode spring commonly used by an endoscope processor is connected with a light guide part of a scope in a point-to-surface form, and the elastic deformation of the electrode spring ensures the reliable connection of the contact surface of the electrode spring and the light guide part of the scope. Therefore, when the contact surface of the light guide part of the scope has a displacement or vibration at a certain angle with the elastic deformation direction of the electrode spring, it is difficult to ensure the reliable connection of the circuit between the electrode spring and the light guide part of the scope, which is not conducive to the stability of the circuit system. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the purpose of the present application is to overcome the deficiencies in the prior art, and provide an electrode spring and an endoscope, which can adapt to the position of the light guide part of the scope by improving the electrode spring, and improve the reliability and stability of the circuit connection between the two.

[0004] The present application provides the following technical solutions:

[0005] In a first aspect, an electrode spring is provided, which comprises at least two spring parts and a base part, the base part has a first direction, the at least two spring parts and the base part are connected, and the at least two spring parts are arranged in parallel and spaced apart in the first direction; wherein the spring part and the base part have an included angle A, and A<90° is satisfied.

[0006] In some embodiments of the first aspect, the spring part has an arc-shaped section and a contact section, one end of the arc-shaped section is connected with the base part, and the arc-shaped section and the contact section are connected at one end close to each other.

[0007] In some embodiments of the first aspect, the contact section has a contact point, the contact point is located on a side of the contact section away from the base part, and the contact point is protrudingly arranged.

[0008] In some embodiments of the first aspect, the contact point is arranged to extend along the extension direction of the contact section.

[0009] In some embodiments of the first aspect, in the first direction, the height of the contact point protruding from the contact section shows a trend of first increasing and then decreasing.

[0010] In some embodiments of the first aspect, in the first direction, the contact point is located in the middle part of the contact section.

[0011] In some embodiments of the first aspect, one end of the contact section away from the arc-shaped section is bent towards the base part.

[0012] In some embodiments of the first aspect, all the spring portions and the base portion are integrally arranged, and an end of the base portion away from the spring portions is arranged as a connecting portion for connecting a circuit.

[0013] In the second aspect, the application further provides an endoscope comprising a mirror body light guide portion and the electrode spring sheet as in any one of the above embodiments, the mirror body light guide portion having a conductive end face for abutting against all the spring portions.

[0014] In some embodiments of the second aspect, the conductive end face is arranged as a planar structure.

[0015] Embodiments of the application have the following advantages:

[0016] The application provides an electrode spring sheet, and an included angle A of less than 90 degrees between the spring portions and the base portion enables the spring portions to contact the mirror body light guide portion at a certain inclination angle. This inclined contact increases the contact area and allows the spring portions to adapt to the position changes (such as displacement or vibration) of the mirror body light guide portion through their own elastic deformation, thereby maintaining stable electrical contact. The at least two spring portions are arranged side by side and spaced apart in the first direction, providing multiple contact points. Even if a certain contact point temporarily fails, other contact points can still maintain circuit connectivity, increasing the redundancy and reliability of the system. This is particularly suitable for medical devices that require high reliability, such as endoscopes. Due to the existence of the included angle A between the spring portions and the base portion, the spring portions can automatically adjust the contact state when facing slight mechanical movement or vibration, ensuring that the contact pressure is evenly distributed on the contact surface. This design avoids the problem of poor contact or premature wear caused by excessive local pressure, and also helps to disperse the current density, reducing the risk of local heating.

Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically defined.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the template herein are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] In the related art, the electrode spring is a commonly used element in various electronic devices, which functions to quickly switch the on-off of the power of the detachable electronic accessories of the electronic device, and to ensure that when the electronic accessories are installed, they can realize reliable circuit connection through the electrode spring.

[0036] The electrode contact terminal can be roughly divided into rigid connection and elastic connection. The rigid connection is to connect two conductive elements by welding, threaded connection and other methods, which is reliable, but cannot realize quick on-off of power. The elastic connection is to connect the electrode spring with a certain elasticity to reliably connect another conductive element in a certain direction. Among them, the endoscope processor is connected with the light guide part of the scope by an elastic connection mode to obtain the image signal of the scope.

[0037] Generally, the electrode spring commonly used by the endoscope processor is connected with the light guide part of the scope in a point-to-surface form, and the elastic deformation of the electrode spring ensures the reliable connection of the spring and the contact surface of the light guide part of the scope. Therefore, when the contact surface of the light guide part of the scope has a displacement or vibration with a certain angle with the elastic deformation direction of the electrode spring, it is difficult to ensure the reliable connection of the circuit between the electrode spring and the light guide part of the scope, which is not conducive to the stability of the circuit system.

[0038] As Figure 1 andFigure 2 To solve the above technical problems, the electrode spring 100 provided by the embodiments of the present application includes at least two spring parts 110 and a base part 120, the base part 120 has a first direction X, the at least two spring parts 110 and the base part 120 are connected, and the at least two spring parts 110 are arranged side by side and spaced apart in the first direction X; wherein the spring part 110 and the base part 120 have an included angle A, and A < 90° is satisfied.

[0039] In these embodiments, the purpose of the design of the new electrode spring 100 is to improve the connection reliability between the electrode spring 100 and the light guide part of the scope in the endoscope processor. The traditional point-to-surface contact mode may not be able to maintain stable connection when facing vibration or displacement, thereby affecting the stability of the circuit system.

[0040] The electrode spring 100 includes at least two spring parts 110 and a base part 120. The base part 120 serves as the basic structure of the electrode spring 100 and has an axis defined as the first direction X. This base part 120 plays a supporting and connecting role, and can also be used to fix the electrode spring 100 to the endoscope processor or other equipment.

[0041] The spring part 110 includes at least two spring parts 110, which are connected to the base part 120 and arranged side by side and spaced apart in the first direction X of the base part 120. Each spring part 110 is designed to have a certain elasticity and can deform when subjected to external force, so that all spring parts 110 can be in contact with the light guide part of the endoscope.

[0042] In addition, there is an included angle A between the spring part 110 and the base part 120, which is less than 90 degrees. The design of this angle allows the spring part 110 to contact the light guide part of the scope at a certain inclination angle, rather than vertically. That is, the spring part 110 can elastically deform to approach or move away from the base part 120. This inclined contact increases the contact area, and allows the spring part 110 to maintain good contact by deforming itself when facing the position change (such as displacement or vibration) of the light guide part of the scope.

[0043] For example, in this embodiment, the number of spring parts 110 is 2. Of course, in other embodiments, the number of spring parts 110 can be 3, 4, 5, 6, 7, etc.

[0044] For example, the included angle between the spring part 110 and the base part 120 can be 30°, 35°, 40°, or 45°, etc.

[0045] When the light guide portion of the scope changes position, the spring portion 110 can adapt to the new position by bending or stretching due to the presence of the included angle A between the spring portion 110 and the base portion 120, thereby maintaining stable electrical contact. The multiple spring portions 110 arranged side by side provide multiple-point contact, enhancing the redundancy and reliability of the connection, so that even if one or several contact points 111 fail, the electrical continuity of the circuit can still be ensured. The elastic design of the spring portion 110 ensures that good contact with the light guide portion of the scope is maintained even in the case of continuous slight vibrations, improving the overall stability of the system.

[0046] For example, when the conductive end face of the conductive terminal of the endoscope light guide portion undergoes an up-down displacement as shown in Figure 3 , the spring portion 110 can compensate for the up-down displacement and ensure reliable connection of the spring portion 110 with the conductive terminal. Among them, multiple spring portions 110 and conductive terminals form multiple-point contact, which increases the actual contact area of the spring portion 110, helps to reduce resistance, and improves the stability of electrical connection.

[0047] For example, as shown in Figure 3 and Figure 4 , the number of spring portions 110 is taken as an example of two. As shown in Figure 3 , when the conductive terminal undergoes clockwise lifting, since two or more spring portions 110 have a certain span in the horizontal direction of the figure, the distance between the left spring portion 110 and the conductive terminal is less than that of the right elastic portion. As shown in Figure 4 , the same applies when the conductive terminal undergoes counterclockwise lifting. Obviously, it is beneficial to reduce the displacement compensation required by the traditional single-touch electrode spring 100, and to improve the contact reliability when the conductive terminal is lifted.

[0048] Obviously, not only does it solve the problem of instability of traditional point-to-surface contact due to mechanical movement, but also improves the anti-interference ability of the system through multiple-point contact and adaptive design.

[0049] As shown in Figure 1 , in some embodiments, the spring portion 110 has an arc segment 113 and a contact segment 112, one end of the arc segment 113 is connected to the base portion 120, and the other end of the arc segment 113 and the contact segment 112 close to each other is connected.

[0050] In these embodiments, each spring portion 110 of the electrode spring 100 is composed of an arc segment 113 and a contact segment 112. The design of these two parts aims to optimize the electrical connection between the electrode spring 100 and the light guide portion of the scope, while improving the stability and reliability of the system.

[0051] The arc segment 113 is curved in shape, with one end connected to the base 120. It provides the ability to elastically deform, so that the spring section 110 can accommodate small angular displacements or vibrations of the scope light guide. Through its curvature design, it can generate appropriate restoring force when subjected to external forces, ensuring that the contact segment 112 can maintain stable contact pressure.

[0052] The contact segment 112 is located near one end of the arc segment 113 and is designed to directly contact the scope light guide. It ensures good electrical contact with the scope light guide, optionally including a specific surface treatment (such as gold plating) to reduce contact resistance. Alternatively, it has a flat surface or a special shape (such as micro-protrusions, grooves, etc.) to increase the contact area and improve the contact quality.

[0053] The arc segment 113 is firmly connected to the base 120 at one end, ensuring the structural integrity of the entire spring section 110. The arc segment 113 and the contact segment 112 are connected to each other at their ends closest to each other, forming a continuous whole. This connection allows the arc segment 113 to deform when subjected to external mechanical stress, while the contact segment 112 remains relatively stable in position, ensuring good contact with the scope light guide.

[0054] When the scope light guide is displaced or vibrates, the arc segment 113 can compensate for these changes through its elastic deformation, allowing the contact segment 112 to maintain a stable position and contact pressure, thereby maintaining reliable electrical connection. The presence of multiple spring sections 110 provides the possibility of multi-point contact. Even if one contact point 111 temporarily loses contact, other contact points 111 can still maintain circuit connectivity, increasing system redundancy and reliability.

[0055] Of course, in other embodiments, the arc segment 113 can be replaced by a V-shaped segment.

[0056] As shown in Figure 1 some embodiments, the contact segment 112 has contact points 111 located on the side of the contact segment 112 facing away from the base 120, and the contact points 111 are protrudingly arranged.

[0057] In these embodiments, the contact segment 112 of the electrode spring 100 is designed with specific contact points 111, which are located on the side of the contact segment 112 facing away from the base 120, and are arranged in a protruding manner. This design further optimizes the electrical connection quality between the electrode spring 100 and the scope light guide.

[0058] The contact points 111 are located on the side of the contact segment 112 facing away from the base 120, ensuring that the contact points 111 directly face and contact the scope light guide. The contact points 111 are designed as protruding structures, which can be dome-shaped, conical, or other geometric shapes that help enhance the contact effect.

[0059] The protruding contacts 111 are capable of generating concentrated pressure upon contact, ensuring stable electrical contact even in the presence of slight vibrations or displacements. This design helps to reduce contact resistance and improve signal transmission efficiency. The design of multiple protruding contacts 111 provides more contact points 111, increasing the redundancy of the circuit connection. Even if a contact 111 temporarily fails, other contacts 111 can still maintain reliable connection, improving the overall reliability of the system.

[0060] Furthermore, the protruding contacts 111 can better adapt to the slight unevenness of the mirror light guide surface, compensating for these differences through their own elastic deformation, ensuring that each contact 111 can be in close contact with the light guide.

[0061] As shown in some embodiments, the contacts 111 are arranged along the extension direction of the contact section 112. Figure 1

[0062] In these embodiments, the contacts 111 of the electrode spring 100 are designed to extend along the extension direction of the contact section 112. This design further optimizes the electrical connection quality between the electrode spring 100 and the mirror light guide, increasing the stability and reliability of the connection by increasing the contact length and area.

[0063] In this embodiment, the contacts 111 can be linear protruding structures, such as long strips or elongated protrusions similar to bristles. By arranging the contacts 111 along the extension direction of the contact section 112, the total area of contact with the mirror light guide is increased, thereby improving the reliability and stability of the electrical connection. Greater contact area helps to reduce the current density per unit area, reducing the likelihood of local heating.

[0064] For example, the spring section 110 is made of a metal sheet structure, and the contacts 111 are made by sheet metal stamping process. Of course, the contacts 111 can also be formed by solid structures provided on the spring section 110.

[0065] As shown in some embodiments, in the first direction X, the height of the contacts 111 protruding from the contact section 112 increases first and then decreases. Figure 1

[0066] In these embodiments, the contacts 111 of the electrode spring 100 are designed with a unique height variation feature: in the first direction X (i.e. the extension direction of the base 120), the height of the contacts 111 protruding from the contact section 112 increases first and then decreases. This design aims to optimize the contact quality between the electrode spring 100 and the mirror light guide, and to enhance the stability and reliability of the connection.

[0067] ​​In other words, along the first direction X, the contact 111 gradually rises from one end of the contact segment 112, reaches a maximum height, and then gradually decreases. This height variation can form a wave-like or mountain-like profile of the contact 111, so that the contact 111 has different protrusion heights at different positions.

[0068] By varying the height of contact point 111, lower pressure can be applied initially, gradually increasing with depth to ensure gentleness during initial contact and stability after deeper contact. This progressive contact method helps reduce potential damage to the surface of the light guide section and minimizes friction during insertion and removal of the light guide section.

[0069] The varying heights of the contacts 111 allow for better adaptation to minor unevenness or deformation on the surface of the light guide section of the mirror, ensuring good contact even on surfaces that are not perfectly flat. The highest contact 111 makes initial contact and establishes a preliminary connection first.

[0070] like Figure 1 As shown, in some embodiments, in the first direction X, the contact 111 is located in the middle of the contact segment 112.

[0071] In these embodiments, the contacts 111 are concentrated in the middle of the contact segment 112, specifically in the central region of the contact segment 112 along the first direction X (extension direction) of the base 120. This design allows the contacts 111 to be evenly distributed within a relatively concentrated area, rather than being scattered across the entire contact segment 112. Concentrating the contacts 111 in the middle of the contact segment 112 ensures that the pressure during contact is concentrated in the most effective area, thereby improving contact efficiency and stability. This concentrated contact helps reduce unnecessary lateral forces and avoids signal transmission problems caused by uneven contact.

[0072] Furthermore, since the contact 111 is located in the middle, when the light guide part of the lens body undergoes slight displacement or vibration (the light guide part 200 of the lens is tilted), the arc segment 113 can compensate for these changes through its own elastic deformation. At the same time, the contact 111 in the middle and the edge of the spring part 110 can still maintain a stable contact position with the light guide part 200 of the lens, forming a triangular support, which is more stable.

[0073] like Figure 1 As shown, in some embodiments, the end of the contact segment 112 away from the arc segment 113 is bent towards the base 120.

[0074] In these embodiments, the contact segment 112 of the electrode spring 100 is designed to be bent towards the base 120 at its end away from the arc segment 113. This design further optimizes the electrical connection quality between the electrode spring 100 and the light guide of the mirror, and enhances the stability and reliability of the connection.

[0075] The end of the contact segment 112 (i.e. the end away from the arc segment 113) is bent towards the base 120. This bent design causes the contact segment 112 to form a structure similar to a hook or L shape, increasing the angle and manner of contact between the contact segment 112 and the light guide of the mirror. By bending the end of the contact segment 112 towards the base 120, the angle of contact between the contact segment 112 and the light guide of the mirror is changed, thereby providing more contact points 111 or tighter contact. This helps to increase the contact area and contact quality, reducing contact resistance.

[0076] The bent design enhances the mechanical stability of the contact segment 112, allowing it to maintain stable contact even in the case of slight vibration or displacement. The bent part of the end of the contact segment 112 can better resist lateral forces, avoiding poor contact caused by external forces.

[0077] For example, the angle of the end of the contact segment 112 away from the arc segment 113 is bent at 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc.

[0078] In some embodiments, all spring segments 110 and the base 120 are integrally arranged, and the end of the base 120 away from the spring segments 110 is arranged as a wiring portion 130 for connecting the circuit.

[0079] In these embodiments, all spring segments 110 and the base 120 of the electrode spring 100 are integrally arranged, and the end of the base 120 away from the spring segments 110 is arranged as a wiring portion 130 for connecting the circuit. This integrated design not only simplifies the manufacturing process, but also enhances the stability and reliability of the structure.

[0080] All spring segments 110 and the base 120 are integrally formed from the same material, forming a continuous and integral structure. This means that there are no additional welding points or connecting parts, reducing potential failure points. The end of the base 120 away from the spring segments 110 extends a specially designed wiring portion 130, which can be directly connected to an external circuit, such as by welding, plugging, etc.

[0081] Clearly, the integrated design reduces assembly steps, lowers production cost, and improves production efficiency and consistency. For mass production, this is a significant advantage. Since the spring portions 110 and the base portion 120 are integrated structure, there is no weak point at the segmented connection, the overall structure is more solid, and can withstand greater mechanical stress without being easily damaged. The integrated design reduces the contact resistance between different components, provides a more direct current path, and thus improves the electrical performance. This helps to reduce signal loss and improve transmission efficiency.

[0082] The current is directly conducted from the terminal portion 130 to the base portion 120, and then transmitted to the mirror body light guide portion through each spring portion 110, respectively. Since the entire structure is integrated, the current path is very short, reducing energy loss. Despite the integrated design, the spring portions 110 still retain sufficient elasticity, which can automatically adjust when facing slight mechanical movement or vibration, and maintain the best contact effect.

[0083] Exemplarily, the metal spring is bent to form the base portion 120 and the spring portions 110. Of course, in other embodiments, the base portion 120 can also be connected to the spring portions 110 by welding.

[0084] As shown in Figure 2 , Figure 3 and Figure 4 , in some embodiments, the present application also provides an endoscope, which comprises a mirror body light guide portion and the electrode spring 100 as described in any of the above embodiments, and the mirror body light guide portion has a conductive end face for abutting against all the spring portions 110.

[0085] In these embodiments, the present application also provides an endoscope, which comprises a mirror body light guide portion and the electrode spring 100 as described in any of the above embodiments. In particular, the mirror body light guide portion has a conductive end face for abutting against all the spring portions 110.

[0086] The light guide portion of the scope is a critical part of the endoscope, and the electrode spring 100, with the design described in any of the preceding embodiments, ensures good contact between it and the light guide portion of the scope. The conductive end face of the light guide portion of the scope directly contacts all the spring portions 110 of the electrode spring 100, providing a very short and efficient current path, reducing energy loss, and improving signal transmission efficiency. Since each spring portion 110 can form an independent contact point 111 with the conductive end face, even if a certain contact point 111 fails, other contact points 111 can still maintain reliable circuit connection, increasing the redundancy and reliability of the system. The direct contact between the conductive end face and the spring portions 110 ensures stable contact pressure, reduces contact resistance, and improves the quality of electrical connection. The design of the spring portions 110 allows them to adapt to changes in the position of the light guide portion of the scope (such as slight vibration or displacement), and maintain a stable contact state through their own elastic deformation.

[0087] When the electrode spring 100 is assembled with the light guide portion of the scope, the conductive end face will be in close contact with all the spring portions 110, ensuring efficient conduction from the electrode spring 100 to the light guide portion of the scope. Since the spring portions 110 of the electrode spring 100 have a certain elasticity, they can automatically adjust the contact state when faced with slight mechanical movement or vibration, maintaining optimal contact effect and ensuring that the quality of signal transmission is not affected.

[0088] As shown in FIG. 1, in some embodiments, the conductive end face is provided in a planar structure. Figure 2

[0089] In these embodiments, the conductive end face of the light guide portion of the scope of the endoscope is provided in a planar structure. This design choice aims to optimize the quality of electrical connection and ensure stable contact between the electrode spring 100.

[0090] The conductive end face is a flat surface without obvious protrusions or depressions. Exemplarily, materials with good electrical conductivity and wear resistance, such as gold-plated copper, stainless steel, etc., are usually chosen.

[0091] The planar structure of the conductive end face provides a simple and consistent contact interface, allowing all the spring portions 110 of the electrode spring 100 to be uniformly contacted, reducing problems caused by uneven contact. The flat conductive end face can ensure that all the spring portions 110 are contacted at the same level, thereby improving the consistency and reliability of the contact. Even with slight mechanical movement or vibration, the planar structure can maintain a stable contact state.

[0092] ​Obviously, as a flat structure, the contact area can be maximized, the current density per unit area can be reduced, the possibility of local heating can be reduced, and the signal transmission efficiency can be improved. For the electrode patch 100 with multiple contacts 111, the flat conductive end face can form good contact with all the contacts 111 at the same time, enhancing the redundancy and reliability of the system.

[0093] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not limiting, and thus other examples of the example embodiments can have different values.

[0094] It should be noted that like reference numerals and letters refer to like items in the several views of the drawings, and as a result, once an item is defined in one view, it need not be further defined and explained in subsequent views.

[0095] The above-described embodiments are merely illustrative of several embodiments of the present application, and the description is relatively specific and detailed, but should not be construed as limiting the scope of the present application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
