[0001] This application relates to the technical field of connectors, and more particularly to a hose clamp finger connector. Background Technology

[0002] With the rapid development of ultra-high voltage (UHV) technology, intercity high-speed railways and urban rail transit, as well as new energy vehicle charging piles, the demand for high-voltage connection technology will see significant growth, indicating a broad market prospect. High-voltage transmission technology plays a crucial role in UHV power transmission in smart grids, maglev train operation, new energy storage and fast charging, directly affecting the safety, reliability, and advancement of the system. Currently, power transmission and distribution equipment is evolving towards miniaturization, lightweighting, and high integration. This not only requires electrical connectors to have stronger high-voltage resistance but also needs to consider environmental adaptability, compact structure, lightweighting, and ease of installation.

[0003] However, existing contact types on the market, such as spring contacts, clover contacts, and watch strap contacts, generally face problems such as high assembly difficulty, complex structural design, and insufficient current carrying capacity, and urgently need innovation and improvement. Utility Model Content

[0004] The purpose of this application is to provide a hose clamp finger connector that, while meeting the electrical performance requirements of high voltage and high current, adopts a compact and miniaturized structure, reducing assembly space to adapt to more application scenarios.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On one hand, a hose clamp finger connector is provided, comprising: a connecting spring and at least two finger members, each finger member comprising a main body, a contact plate, a fixing part, and a contact foot. The main body has a first end and a second end. The contact plate is arc-shaped and connected to the second end. The contact foot is capsule-shaped and disposed at the first end. The fixing part is disposed between the first end and the second end. The upper and lower ends of the connecting spring are provided with fixing positions that can cooperate with the fixing part. The left and right ends of the connecting spring are connected to form a ring structure. The finger members are divided into two groups arranged vertically and horizontally. The contact plates of the two groups of finger members are arranged opposite to each other. The fixing parts of the finger members in the same group are correspondingly connected to the fixing positions on the same side.

[0007] Furthermore, both the fixing part and the contact foot part protrude from the main body part, and the protrusion height of the contact foot part is greater than the protrusion height of the fixing part.

[0008] Furthermore, the fixing part consists of two cylinders protruding from the main body, and the fixing position consists of two cylindrical holes, with the cylinders riveted into the cylindrical holes.

[0009] Furthermore, the connecting spring includes a main body and multiple separate parts. The left and right ends of the main body are spaced apart to form connection ports. The separate parts are disposed at the connection ports and are respectively connected to the left and right ends of the main body to expand the inner diameter of the connecting spring.

[0010] Furthermore, one end of the main body has a first snap-fit ​​position and the other end has a first snap-fit ​​part. One end of the split part has a second snap-fit ​​part that engages with the first snap-fit ​​position, and the other end has a second snap-fit ​​position that engages with the first snap-fit ​​part.

[0011] Furthermore, the connecting spring includes multiple bases and multiple deformable parts. The multiple bases are divided into two groups, one above the other, and the bases in each group are spaced apart. The bases in one group are spaced apart from the two bases in the other group. The fixing position is located on the base. The two ends of the deformable parts are respectively connected to the upper and lower bases, and a gap is left between two adjacent deformable parts.

[0012] Furthermore, the annular structure formed by the connecting spring has an inward protrusion at the middle position and outwards at both ends.

[0013] Furthermore, the middle position of the annular structure formed by the connecting spring protrudes outward, while both ends are arranged inward.

[0014] Furthermore, the main body, the contact plate, the fixing part, and the contact foot are integrated into one piece.

[0015] Furthermore, the contact finger is made of copper alloy; and / or the connecting spring is made of elastic stainless steel.

[0016] The beneficial effects of this application are as follows: The contact finger includes a main body, a contact plate, a fixing part, and a unique capsule-shaped contact foot. The main body has a first end and a second end. The contact plate is arc-shaped and connected to the second end for forming conductive contact with the corresponding conductor. The capsule-shaped contact foot is located at the first end, designed to ensure smooth sliding during insertion and mating while maintaining good contact with the contact wall, thereby reducing contact resistance. The fixing part is located between the first and second ends of the main body for fixed connection with the connecting spring. The connecting spring has fixing positions at both its upper and lower ends, which can cooperate with the fixing part of the contact finger. The left and right ends of the connecting spring connect to form a ring structure, a design that allows the contact fingers to be stably connected together. The contact fingers are divided into two groups arranged vertically and horizontally, with the contact plates of the two groups facing each other to form a tight and elastically adjustable connection structure. The fixing parts of the contact fingers in the same group are connected to the fixing positions on the same side, thereby ensuring the stability and reliability of the entire connector.

[0017] During operation, when the hose clamp contact finger connector is installed in the conductive circuit of high-voltage switchgear, the contact portion contacts the corresponding conductor and forms a good conductive connection. Simultaneously, the capsule-shaped contact feet ensure smooth sliding during insertion and mating, reducing installation difficulty. The connecting spring provides the necessary elasticity, allowing the contact fingers to adapt to different installation conditions and pressure changes, maintaining a stable conductive connection.

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0031] like Figures 1-8As shown, this embodiment provides a hose clamp finger connector, including: a connecting spring 1 and at least two finger members 2. Each finger member 2 includes a main body 201, a contact plate 202, a fixing part 203, and a contact foot 204. The main body 201 has a first end and a second end. The contact plate 202 is arc-shaped and connected to the second end. The contact foot 204 is capsule-shaped and disposed at the first end. The fixing part 203 is disposed between the first end and the second end. The upper and lower ends of the connecting spring 1 are provided with fixing positions 108 that can cooperate with the fixing part 203. The left and right ends of the connecting spring 1 are connected to form a ring structure. The finger members 2 are divided into two groups arranged vertically and horizontally. The contact plates 202 of the two groups of finger members 2 are arranged opposite each other. The fixing parts 203 of the finger members 2 in the same group are correspondingly connected to the fixing positions 108 on the same side.

[0032] A hose clamp contact finger connector is a device component designed for electrical connections in high-voltage, high-current environments. It mainly consists of a connecting spring 1 and at least two contact fingers 2, which are further subdivided into a body part 201, a contact part 202, a fixing part 203, and a contact foot part 204.

[0033] During operation, the main body 201 of the contact finger 2 serves as a support structure, with its first and second ends respectively supporting the contact foot 204 and the contact plate 202. The contact plate 202 is designed in an arc shape to better match and contact the contact wall of the mating component (such as another connector or conductive element). The contact foot 204 is designed in a capsule shape. This special shape not only facilitates smooth sliding during mating but also ensures a tight fit with the contact wall, thereby reducing contact resistance.

[0034] The connecting spring 1 serves to fix and connect the contact fingers 2 together. It has fixing positions 108 at both its upper and lower ends, which can cooperate with the fixing part 203 of the contact fingers 2 to achieve a stable connection. The left and right ends of the connecting spring 1 connect to form a ring structure, which not only enhances the overall stability of the connector but also provides a reliable support frame for the contact fingers 2.

[0035] When the mating component is inserted into the connector, the contact portion 202 of the contact finger 2 first contacts its contact wall. As insertion deepens, the contact foot portion 204 gradually conforms to the contact wall, further enhancing the reliability of the electrical connection. Simultaneously, the annular structure of the connecting spring 1 adapts to the shape and size of the mating component, ensuring a stable electrical connection throughout operation.

[0036] Overall, the hose clamp finger connector, through its carefully designed finger piece 2 and connecting spring 1, ensures reliable electrical connections under high voltage and high current environments. The arc-shaped design of the contact piece 202 and the capsule-shaped design of the contact foot 204 together reduce contact resistance and improve electrical transmission efficiency. The connector's overall structure is compact, and the rational layout of the finger piece 2 and connecting spring 1 makes the entire connector easier to install. This compact structure also allows the connector to adapt to more application scenarios, improving its flexibility and versatility. Crucially, the capsule-shaped design of the contact foot 204 not only provides smooth sliding during mating but also ensures a tight fit with the contact wall, enabling the connector to maintain a stable electrical connection during long-term operation and reducing the risk of electrical failures due to poor contact. Furthermore, the hose clamp finger connector, through its rational structural design and high-quality material selection, ensures high reliability and long lifespan in harsh working environments. The annular structure of the connecting spring 1 and the robust connection of the finger piece 2 allow the connector to withstand significant mechanical stress and temperature changes, thus guaranteeing its long-term stable electrical performance.

[0037] Furthermore, both the fixing part 203 and the contact part 204 protrude from the main body part 201, and the protrusion height of the contact part 204 is greater than that of the fixing part 203. The higher protrusion of the contact part 204 relative to the fixing part 203 allows for better contact with the contact wall surface, thereby enhancing the tightness and stability of the contact. When the connector is subjected to external forces (such as insertion / removal operations), the high protrusion design of the contact part 204 helps maintain good contact between the connector and the contact wall surface, reducing poor contact caused by vibration or displacement. The capsule-shaped design of the contact part 204 not only increases the contact surface area but also allows for a more even distribution of pressure when subjected to force, avoiding wear or deformation caused by excessive local stress. Moreover, the capsule shape also gives the contact part 204 a certain degree of elasticity, enabling it to adapt to minor unevenness of the contact wall surface to a certain extent, further reducing contact resistance.

[0038] Optionally, the fixing part 203 consists of two cylinders protruding from the main body 201, and the fixing position 108 consists of two cylindrical holes, with the cylinders riveted into the cylindrical holes. Two protruding cylinders are designed as fixing parts 203 on the main body 201 of the contact finger 2. The riveting process first ensures that the cylinders of the contact finger 2 are precisely aligned with the cylindrical holes of the connecting spring 1. Then, pressure is applied to the ends of the cylinders using a riveting tool, causing the material to undergo plastic deformation and fill the cylindrical holes, ultimately forming a rivet head structure, achieving a tight and secure connection. This connection method not only provides high-strength mechanical support, resisting mechanical stress and temperature changes in harsh working environments, but also ensures that the contact piece 202 and contact foot 204 of the contact finger 2, supported by the connecting spring 1, form reliable electrical contact with the mating components, meeting the electrical connection requirements under high voltage and high current environments. From a beneficial perspective, this riveting fixing method significantly improves the overall stability and connection strength of the connector, reducing the risk of electrical failures caused by loosening or breakage. Simultaneously, the riveting process simplifies the assembly process, reduces the use of fasteners, lowers assembly costs and time, and improves production efficiency and product quality. Furthermore, this design enhances the connector's electrical performance, reduces contact resistance, and improves electrical transmission efficiency. More importantly, the standardized design of the contact fingers 2 and connecting springs 1 allows for interchangeability and combination, improving the connector's versatility and flexibility, enabling it to adapt to more application scenarios, and reducing spare parts costs and inventory pressure.

[0039] It is worth noting that there are strict requirements for the retaining force after riveting, the stability of the contact finger 2, and the integrity of the connecting spring 1. Specifically, the retaining force after riveting must reach or exceed 100N to ensure that the contact finger 2 will not fall off under extreme conditions, and the connecting spring 1 must not crack or break during the stress process. To meet these requirements, the connector adopts several measures in its design and manufacturing process:

[0040] Riveting process optimization: High-quality rivets and riveting tools are selected to ensure accuracy and stability during the riveting process. Riveting parameters (such as riveting force and riveting time) are strictly controlled to ensure consistent and reliable riveting quality. Advanced riveting techniques, such as vibration riveting or hot riveting, are employed to improve riveting strength and holding force.

[0041] The matching design of the contact finger 2 and the connecting spring 1: The cylinder of the contact finger 2 and the cylindrical hole of the connecting spring 1 are precisely matched in size and shape to reduce assembly gaps and stress concentration. Both the contact finger 2 and the connecting spring 1 are made of high-strength, corrosion-resistant materials to improve their fatigue and corrosion resistance. Precise manufacturing processes and strict quality control ensure the dimensional accuracy and surface quality of the contact finger 2 and the connecting spring 1.

[0042] Performance Testing and Verification: Rigorous tensile testing is performed on the connectors to ensure that the retaining force after riveting meets or exceeds the requirement of 100N. Vibration and shock tests are conducted to evaluate the stability and durability of the connectors under dynamic loads. Environmental simulation tests (such as high temperature, low temperature, humidity, etc.) are used to check the electrical and mechanical properties of the connectors under different environments.

[0043] In some embodiments, the connecting spring 1 includes a main body 101 and a plurality of separate parts 102. The main body 101 has connecting ports spaced apart at its left and right ends. The separate parts 102 are disposed at the connecting ports and connected to the left and right ends of the main body 101 respectively, thereby increasing the inner diameter of the connecting spring 1. The main body 101, as the main structural part of the connecting spring 1, undertakes the dual tasks of electrical connection and mechanical support. The separate parts 102 are cleverly disposed at the left and right ends of the main body 101 and connected to it through the connecting ports. This design allows the separate parts 102 to expand or contract relative to the main body 101 to a certain extent when needed, thereby flexibly adjusting the inner diameter of the connecting spring 1. The placement of the connecting ports is key to this design. They not only provide space for the separate parts 102 to connect with the main body 101 but also ensure the stability and reliability of the separate parts 102 during the connection process. By precisely controlling the size and shape of the connector, a tight fit between the split component 102 and the main component 101 can be ensured, preventing loosening or poor contact during electrical connection. The split component 102 further enhances the adaptability and flexibility of the connecting springs 1. They can adjust the inner diameter by expanding or contracting according to the actual electrical connection requirements, thus adapting to mating components of different sizes. This design not only improves the connector's versatility but also enables it to more flexibly handle various complex electrical connection scenarios.

[0044] Specifically, one end of the main body 101 has a first snap-fit ​​position 103, and the other end has a first snap-fit ​​portion 104. One end of the split component 102 has a second snap-fit ​​portion 105 that engages with the first snap-fit ​​position 103, and the other end has a second snap-fit ​​position that engages with the first snap-fit ​​portion 104. The left and right ends of the main body 101 are cleverly designed to have different snap-fit ​​functions. One end has a first snap-fit ​​position 103, which is a structure specifically designed to engage with the split component 102, ensuring that the split component 102 can be firmly connected to the main body 101. The other end has a first snap-fit ​​portion 104, which is an outwardly protruding structure used to engage with the second snap-fit ​​position on another split component 102, thereby realizing the series connection between multiple split components 102. One end of the split component 102 has a second snap-fit ​​portion 105 that engages with the first snap-fit ​​position 103 on the main body 101. The shape and size of this snap-fit ​​part match the first snap-fit ​​position 103, ensuring that the two can be tightly snapped together, preventing loosening or detachment during electrical connection. The other end of the split part 102 has a second snap-fit ​​position that engages with the first snap-fit ​​part 104 on the main body 101. This second snap-fit ​​position also has precise dimensions and shape for a secure snap-fit ​​connection with the first snap-fit ​​part 104. Through this snap-fit ​​method, a tight and stable connection is established between the main body 101 and the split part 102, as well as between the split parts 102 themselves. This connection can withstand electrical loads under high voltage and high current conditions, and also resist mechanical stress and temperature changes in harsh working environments. Furthermore, due to the snap-fit ​​structure, the connecting spring 1 maintains overall stability and reliability when adjusting the inner ring diameter.

[0045] Furthermore, this snap-fit ​​design makes the assembly and disassembly of the connecting spring 1 much easier. Users can easily connect the split component 102 to the main component 101, or connect multiple split components 102 in series, through a simple snap-fit ​​operation. Similarly, when it is necessary to disassemble the connecting spring 1, it can be achieved by releasing the snap-fit ​​structure. This design not only improves the ease of use of the connector, but also reduces maintenance costs and time.

[0046] In the further innovative design of the hose clamp contact finger connector, the structure of the connecting spring 1 has been further refined, particularly with the design of multiple bases 106 and deformable parts 107. This not only improves the flexibility and adaptability of the connecting spring 1 but also significantly enhances its stability and reliability during electrical connection. Specifically, the connecting spring 1 consists of multiple bases 106 and multiple deformable parts 107. These bases 106 are cleverly divided into upper and lower groups, and the bases 106 in each group are spaced apart. In particular, the bases 106 in one group are arranged to correspond to the spacing between the two bases 106 in the other group. This layout makes the connecting spring 1 more compact and flexible in structure. Fixing positions 108 are carefully set on the bases 106. These fixing positions 108 are not only used to connect the contact finger 2 but also ensure the stability and accuracy of the connecting spring 1 during electrical connection. Through the firm connection between the fixing positions 108 and the contact finger 2, the connecting spring 1 can reliably transmit electrical signals and current while resisting various mechanical stresses and temperature changes. The deformable portion 107, as the core part of the connecting spring 1, is connected to the upper and lower bases 106 at both ends. This connection method allows the deformable portion 107 to elastically deform under external force, thereby adapting to mating parts of different sizes. Simultaneously, gaps are left between adjacent deformable portions 107. These gaps not only provide sufficient deformation space for the deformable portion 107 but also avoid excessive stress concentration during deformation, thus extending the service life of the connecting spring 1. Moreover, this design also gives the connecting spring 1 better contact performance during electrical connection. The elastic deformation of the deformable portion 107 ensures good electrical contact between the contact finger 2 and the mating part, reducing contact resistance and the risk of electrical failure. Furthermore, due to the gaps between the deformable portions 107 and the spacing of the bases 106, the connecting spring 1 has better overall heat dissipation performance, effectively dissipating the heat generated during electrical connection and maintaining stable operation of the connector.

[0047] It should be noted that the connecting spring 1 has an overall serpentine structure, and the deformable part 107 is designed to be streamlined, so that the connecting spring 1 has a certain degree of tensile strength, further increasing the tolerance range and reducing the assembly difficulty.

[0048] In some embodiments, such as Figure 1As shown, the annular structure formed by the connecting spring 1 has an inwardly protruding middle section and outwardly extending ends. This unique shape allows the connecting spring 1 to fit tightly against the female end or corresponding assembly position during assembly. When the hose clamp contact connector is assembled onto the female end, the connecting spring 1 bends inward, and the entire connector is assembled within the groove of the female end. This design ensures the stability and accuracy of the connector during assembly. The contact portion 204 achieves elastic contact with the inner wall of the sleeve, meaning that the contact portion 204 can flexibly adapt to changes in the shape and size of the inner wall of the sleeve when the connector is mated with the mating component. When the contact portion 202 is pressed down, the contact portion 204 slides axially along the inner wall of the sleeve. During this process, the connecting spring 1 is compressed and undergoes elastic deformation. Through the anti-deformation force of the connecting spring 1, sufficient positive pressure can be generated between the contact portion 202 and the mating male pin, thereby ensuring good elastic contact between them. This design not only improves the stability and reliability of the electrical connection but also reduces the risk of contact resistance and electrical failure.

[0049] As an optional specific implementation plan, such as Figure 2 As shown, the annular structure formed by the connecting spring 1 has a protrusion at the middle and inwards at both ends. The assembly method is similar to the above scheme, but the specific shape of the hose clamp contact connector is different. When the hose clamp contact connector is assembled on the male end, the connecting spring 1 bends towards the male end, and the hose clamp contact connector is assembled in the male end groove; the contact foot 204 contacts the inner wall of the male end groove. During insertion, the contact piece 202 presses down, and the contact foot 204 slides axially along the cylindrical wall of the male end, squeezing the connecting spring 1 to cause elastic deformation. The deformation resistance of the connecting spring 1 provides positive pressure for the contact between the contact piece 202 and the sleeve to maintain good elastic contact.

[0050] Preferably, the main body 201, the contact plate 202, the fixing part 203, and the contact foot 204 are integrated as a single piece. This integrated design means there are no additional connection points or interfaces between these parts, thus reducing potential points of failure. During electrical connection, any connection point or interface can be a source of electrical faults or poor contact. By designing these parts as a single piece, these potential problems can be minimized, improving the electrical connection stability and reliability of the connector. Furthermore, the integrated design enhances the mechanical strength of the connector. When dealing with dynamic loads such as vibration and shock, the various parts of the connector need to work together to absorb and disperse the stress generated by these loads. By designing the main body 201, contact plate 202, fixing part 203, and contact foot 204 as a single piece, it can be ensured that these parts can deform and recover as a whole when subjected to external forces, thereby improving the durability and service life of the connector.

[0051] Optionally, the contact finger 2 is made of copper alloy. Due to the high conductivity and high strength of the copper alloy contact finger 2, the number of contact fingers 2 can be reduced while maintaining the same current carrying capacity, thereby simplifying the connector structure and reducing costs. And / or the connecting spring 1 is made of elastic stainless steel. The elastic stainless steel connecting spring 1 can provide sufficient mechanical support to ensure good contact and electrical connection between the contact finger 2 and the mating part.
