The connector body has a first connecting end for connecting to an armature assembly and a second connecting end for connecting to a moving spring contact bridge at its longitudinal ends. The first connecting end is configured to be fixedly connected to the armature assembly at a first connecting position, and the second connecting end is configured to be fixedly connected to the moving spring contact bridge at a second connecting position.

Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a moving spring contact bridge connector, an armature moving spring mechanism, and a relay. Background Technology

[0002] Normally open pressure, also known as contact pressure or contact force, refers to the positive pressure exerted between the moving and stationary contacts of a relay when the normally open contacts are closed. Normally open pressure is one of the core parameters ensuring reliable relay operation, and its main functions are as follows: 1. Reducing contact resistance: Lower contact resistance means a smaller voltage drop across the contacts when energized, resulting in lower power loss, less heat generation, and higher energy efficiency; 2. Preventing contact bounce and momentary disconnection: Sufficient normally open pressure provides adequate friction and holding force, effectively suppressing contact bounce and vibration, ensuring stable contact connection, and avoiding unstable arcing or signal glitches; 3. Improving vibration and shock resistance: In harsh environments (such as industrial equipment and vehicles), equipment may continuously vibrate or be subjected to impacts. Insufficient contact pressure can cause momentary micro-separation between contacts, generating arcs, which can burn the contacts, generate electromagnetic interference, and even cause circuit malfunctions. Sufficient normally open pressure can firmly "lock" the contacts, resisting the effects of external mechanical forces.

[0003] Because the current carrying capacity of relay products is increasing, as shown in the attached... Figure 3 The existing armature moving spring mechanism shown in the figure has a structural limitation that the dynamic engagement pressure value of the relay product cannot be significantly improved due to the fact that the two ends of the moving spring contact bridge connector 1' are basically the same width. In high current carrying applications, the low dynamic engagement pressure and high contact resistance will lead to severe contact heating and cause relay failure risk. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dynamic spring contact bridge connector, which mainly solves the technical problem of poor dynamic engagement pressure value in existing relay products.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A movable spring contact bridge connector includes a connector body. The longitudinal ends of the connector body are respectively formed into a first connecting end for connecting with an armature assembly and a second connecting end for connecting with a movable spring contact bridge. The first connecting end is configured to be fixedly connected to the armature assembly at a first connecting position, and the second connecting end is configured to be fixedly connected to the movable spring contact bridge at a second connecting position. The lateral width of the first connecting end at the first connecting position is greater than the lateral width of the second connecting end at the second connecting position.

[0007] Furthermore, the lateral width of the connector body gradually narrows from the first connecting end to the second connecting end.

[0008] Furthermore, the connector body is generally in the form of a triangular sheet structure or a triangular sheet structure with rounded corners.

[0009] Furthermore, at the first connection position of the first connection end, several first connection points are arranged horizontally at intervals, and the horizontal width between the two farthest first connection points is defined as L1. At the second connection position of the second connection end, several second connection points are arranged horizontally at intervals, and the horizontal width between the two farthest second connection points is defined as L2. Then L1 > L2.

[0010] Furthermore, three first connection points are arranged horizontally at equal intervals at the first connection position of the first connection end, and two second connection points are arranged horizontally at the second connection position of the second connection end. The horizontal width between the two first connection points at the two ends in the first connection position is L1, and the horizontal width between the two second connection points in the second connection position is L2.

[0011] Furthermore, both the first and second connection points are riveted protrusion structures.

[0012] Based on the same inventive concept, this utility model also provides an armature moving spring mechanism, including an armature assembly, a moving spring contact bridge and the aforementioned moving spring contact bridge connector, wherein the armature assembly includes an armature and an insulating member connected to the driving end of the armature, the first connecting end of the moving spring contact bridge connector is connected to the insulating member, and the second connecting end of the moving spring contact bridge connector is connected to the moving spring contact bridge.

[0013] Furthermore, the insulating component is made of plastic, and the insulating component and the drive end of the armature are integrally molded by injection molding.

[0014] Based on the same inventive concept, this utility model also provides a relay, including the above-mentioned armature moving spring assembly.

[0015] Furthermore, the relay is an AC relay, a DC relay, a monostable relay, or a magnetic latching relay.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] In the moving spring contact bridge connector, armature moving spring mechanism, and relay described in this utility model, the lateral width of the first connecting end corresponding to the first connecting position is configured to be greater than the lateral width of the second connecting end corresponding to the second connecting position. In this way, by increasing the width of the first connecting end, the overall strength of the connector body can be effectively enhanced, thereby increasing the dynamic contact pressure between the contacts after the relay product is engaged, thereby reducing the contact resistance of the product. This makes it more suitable for high load current carrying applications and improves the defect problem of severe contact heating, which in turn helps to improve the stability and service life of the product.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0025] Please refer to the appendix. Figure 1 Appendix Figure 2An embodiment of this utility model provides a movable spring contact bridge connector, including a connector body 1. The longitudinal ends of the connector body 1 are respectively formed with a first connecting end 11 for connecting to an armature assembly 2 and a second connecting end 12 for connecting to a movable spring contact bridge 3. The first connecting end 11 is configured to be fixedly connected to the armature assembly 2 at a first connecting position, while the second connecting end 12 is configured to be fixedly connected to the movable spring contact bridge 3 at a second connecting position. The lateral width of the first connecting end 11 at the first connecting position is greater than the lateral width of the second connecting end 12 at the second connecting position. It is understood that, compared to the attached... Figure 3 The spring-loaded contact bridge connector structure shown has two ends with approximately equal width. In this embodiment, the lateral width of the first connecting end 11 at the first connecting position is configured to be greater than the lateral width of the second connecting end 12 at the second connecting position. Thus, by increasing the width of the first connecting end 11, the overall strength of the connector body 1 can be effectively enhanced, thereby increasing the dynamic contact pressure between the contacts after the relay product is engaged, thereby reducing the contact resistance of the product. This makes it more suitable for high-load current-carrying applications and improves the problem of severe contact heating, which in turn helps to improve the stability and service life of the product.

[0026] Please refer to the appendix. Figure 1 Appendix Figure 2 In one preferred embodiment, the lateral width of the connector body 1 gradually narrows from the first connecting end 11 to the second connecting end 12. The connector body 1 is generally a triangular sheet structure or a triangular sheet structure with rounded corners. However, those skilled in the art should understand that in other embodiments, the specific structure of the connector body 1 is not limited to the specific implementation disclosed in this embodiment, and those skilled in the art can also adaptively modify the specific shape of the connector body 1 while meeting the dynamic engagement pressure requirements.

[0027] Please refer to the appendix. Figure 1 Appendix Figure 2In one preferred embodiment, a plurality of horizontally spaced first connection points 111 are provided at the first connection position of the first connection end 11, and the horizontal width between the two farthest first connection points 111 is defined as L1. A plurality of horizontally spaced second connection points 121 are provided at the second connection position of the second connection end 12, and the horizontal width between the two farthest second connection points 121 is defined as L2. Therefore, L1 > L2. In this embodiment, by configuring L1 > L2, the width of the moving spring is increased, the dynamic engagement pressure of the product is increased, the contact resistance of the product is reduced, and heat generation is reduced, making it more suitable for high-current carrying applications. Preferably, the overall moving spring has an inverted triangular structure that gradually narrows, which also helps to ensure a uniform distribution of mechanical stress in the overall moving spring. Compared with the existing equal-width structure where stress is concentrated at the first connection end, the overall stress of the moving contact bridge connector in this embodiment is evenly distributed across the entire structure from the first connection end to the second connection end. Increased dynamic engagement pressure can solve the problem of severe heat generation and temperature rise under high current carrying caused by excessive relay contact resistance. Uniform mechanical stress distribution can reduce the risk of spring breakage during operation due to excessive local stress and the problem of severe force attenuation in areas of high stress at high temperatures.

[0028] Please refer to the appendix. Figure 1 Appendix Figure 2 In one preferred embodiment, three horizontally equidistant first connection points 111 are provided at the first connection position of the first connection end 11, and two horizontally equidistant second connection points 121 are provided at the second connection position of the second connection end 12. The horizontal width between the two first connection points 111 at the two ends in the first connection position is L1, and the horizontal width between the two second connection points 121 in the second connection position is L2. In this embodiment, compared with the attached... Figure 3The existing structure shown improves the two connection points of the first connection end to three connection points. Using three spaced connection points 111 reduces the local mechanical stress at the connection point between the moving spring contact bridge connector and the armature assembly 2 during relay operation, thereby reducing the risk of a significant drop in dynamic engagement pressure due to excessive stress causing thermal decay in the moving spring contact bridge connector. When the dynamic engagement pressure increases, the original connection structure using two connection points at the first connection end 11 will result in high local stress at the connection point, which can easily lead to the risk of breakage of the moving spring contact bridge connector during product use. This embodiment, by setting three first connection points 111 at the first connection end 11, can better disperse stress, reduce the stress level at the point of maximum mechanical stress during relay operation, and thus reduce the risk of breakage of the moving spring contact bridge connector. However, those skilled in the art should understand that in other embodiments, other numbers of connection points can be set at the first connection position of the first connection end 11 and the second connection position of the second connection end 12, and are not limited to the specific implementation disclosed in this embodiment.

[0029] Please refer to the appendix. Figure 1 Appendix Figure 2 In one preferred embodiment, both the first connection point 111 and the second connection point 121 are riveted protrusion structures. In addition, in other embodiments, welding connections can also be made through adaptive changes.

The armature assembly 2 includes an armature 21 and an insulating member 22 connected to the driving end of the armature 21. The first connecting end 11 of the moving spring contact bridge connector is connected to the insulating member 22, and the second connecting end 12 of the moving spring contact bridge connector is connected to the moving spring contact bridge 3. In this embodiment, preferably, the insulating member 22 is made of plastic, and the insulating member 22 and the driving end of the armature 21 are integrally molded as an insert.
