Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a spring and a connector. Background Art

[0002] The spring is a key component in connectors. Its elastic design provides stable mechanical contact for the electrical connection between the male and female pins. Traditional spring-type connectors typically consist of a male pin, a female pin, a spring, and a gland. The female pin has an opening within it, into which the spring is inserted. The gland secures the spring in place within the female pin. When the male pin is inserted into the female pin, the spring's elastic tension grips the male pin, establishing electrical continuity between the two pins.

[0003] However, the contact area between the existing reed and the male pin is too small, which easily generates relatively high contact resistance. Moreover, after the male pin is plugged in and out multiple times, the reed is easily worn, resulting in poor electrical contact with the pin and a short service life. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a reed, aiming to solve the problem of how to increase the service life of the reed and reduce the contact resistance.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0027] See also Figures 1 to 3 The embodiment of the present application provides a reed 100 and a connector having the same. The reed 100 can be detachably connected to a pin to achieve electrical conduction.

[0028] The spring 100 includes an end ring 101 for inserting the pin and a rib 102 with elastic restoring force. It is understandable that the end ring 101 and the rib 102 are both made of conductive material, which can be a metal conductive material, such as copper alloy.

[0029] See also Figures 1 to 3Two end rings 101 are disposed opposite each other. The two end rings 101 are coaxially disposed along the axial direction of the pin, and both end rings 101 have a shrinkage notch 1013 formed at the same position along the axial direction of the pin. It can be understood that by providing the shrinkage notch 1013, the end ring 101 also has a certain elastic restoring force along its radial direction, so that when the pin is inserted into the end ring 101, the end ring 101 can appropriately expand outward. The two ends of the rib 102 are respectively connected to the two end rings 101. The rib 102 has an electrical contact surface 1023. The rib 102 is partially protruded toward the pin, and the electrical contact surface 1023 abuts the peripheral side surface of the pin. Multiple ribs 102 are arranged at intervals along the circumference of the end ring 101, and each electrical contact surface 1023 abuts the peripheral side surface of the pin. A through groove 103 is formed between any two adjacent ribs 102.

[0030] See also Figures 1 to 3 It can be understood that when the pin is inserted into the end ring 101, the pin will squeeze the ribs 102 outward, and the ribs 102 will undergo elastic deformation and under the reaction force, the electrical contact surfaces 1023 will all abut against the peripheral side of the pin; after the pin is separated from the spring 100, the ribs 102 will return to their original shape under the action of the elastic restoring force.

[0031] The spring 100 provided in the embodiment of the present application includes an end ring 101 and a plurality of ribs 102. When a pin is inserted into the two end rings 101, there is surface-to-surface contact between any rib 102 and the pin, thereby increasing the electrical contact area 1023 between the spring 100 and the pin and reducing the contact resistance. In addition, the surface-to-surface contact between the rib 102 and the pin can reduce the wear of the pin on the rib 102, thereby increasing the plugging and unplugging service life of the spring 100, and can also provide sufficient clamping force for the pin, so that the pin is stably clamped in the spring 100.

[0032] It is understandable that the reduction of contact resistance can reduce the temperature rise of the reed 100 during use, thereby preventing the temperature from being too high.

[0033] See also Figures 1 to 3 Optionally, the elastic restoring force of rib 102 allows electrical contact surfaces 1023 of rib 102 to stably contact the side surface of the pin, ensuring reliable electrical contact when the pin is inserted. The electrical contact surfaces 1023 are distributed along the side surface of the pin, further increasing the number of contact points and thereby enhancing the stability and reliability of the electrical contact between reed 100 and the pin.

[0034] It can be understood that the two end rings 101 of the spring 100 are coaxially arranged, and both end rings 101 have a shrinkage notch 1013, which can provide shrinkage space when the pin is inserted, reduce the plugging and unplugging force, and improve the plugging and unplugging life of the connector and its ease of use.

[0035] See also Figures 1 to 3 Optionally, the two ends of the rib 102 are connected to the two end rings 101, forming a closed mechanical structure as a whole, which helps to improve the overall mechanical strength of the reed 100 and prevent deformation and loosening. The elastic restoring force of the rib 102 ensures that the pin is tightly fixed after insertion.

[0036] See also Figures 1 to 3 In some embodiments, the rib 102 includes an abutting portion having the electrical contact surface 1023 and protruding toward the pin, and a positioning portion 1022 connected to the end ring 101. There are two positioning portions 1022, and the two positioning portions 1022 are respectively connected to the two end rings 101, and the two positioning portions 1022 are respectively located at both ends of the abutting portion.

[0037] See also Figures 1 to 3 Optionally, the centerline of the abutment end ring 101 is raised, allowing the electrical contact surface 1023 to precisely contact the pin surface, providing stable electrical contact force and reducing the possibility of poor electrical contact. This refined design can effectively improve the quality of electrical connections, especially for applications requiring high-frequency signals or low resistance.

[0038] The positioning portion 1022 is connected to the end ring 101 to ensure a tight connection between the rib 102 and the end ring 101 , thereby enhancing the fixation of the rib 102 and preventing the rib 102 from being separated or loosened during long-term use, thereby extending the service life of the entire reed 100 .

[0039] See also Figures 1 to 3 In some embodiments, the abutting portion and the positioning portion 1022 are both in the shape of long strips, and the length direction of the abutting portion is staggered with the length direction of the positioning portion 1022.

[0040] Optionally, the abutment portion and the positioning portion 1022 are in the shape of long strips and are staggered, so that the rib 102 is in the shape of a bow as a whole, so that the force applied by the pin to the rib 102 is along the radial direction of the end ring 101, and an interaction force between the surfaces is generated, which can improve the clamping of the pin and effectively alleviate the damage caused by stress concentration during the plugging and unplugging process, thereby improving the plugging and unplugging life.

[0041] See also Figures 1 to 3 In some embodiments, the positioning portion 1022 and the abutting portion are integrally formed, and both the positioning portion 1022 and the abutting portion are made of conductive metal materials, so that they can be integrally formed through a stamping process.

[0042] See also Figures 1 to 3In some embodiments, and / or the rib 102 is integrally formed with the end ring 101, and the rib 102 and the end ring 101 are both made of conductive metal materials, so that they can be integrally formed through a stamping process.

[0043] Optionally, in this embodiment, the end ring 101 and the rib 102 are both made of copper alloy. Copper alloy is a metal with good electrical conductivity. Copper alloy is usually plated with gold or silver to improve contact performance and oxidation resistance.

[0044] Copper alloys also possess excellent machinability and can be processed through methods such as stamping, drawing, and cutting. Their ductility and plasticity allow them to deform during cold working without fracturing. Their high toughness and low fracture tendency allow stamped products to have smooth surfaces and precise shapes.

[0045] Optionally, the integral molding of the abutting portion and the positioning portion 1022 as well as the rib 102 and the end ring 101 reduces the number of assembly steps between components and simplifies the manufacturing process.

[0046] Optionally, the rib 102 may also be connected to the end ring 101 through a welding process, which is not limited here and can be selected according to actual conditions.

[0047] See also Figures 1 to 3 In some embodiments, each of the ribs 102 is arranged along the axial direction of the pin, that is, the length direction of the rib 102 is parallel to the axial direction of the pin.

[0048] See also Figures 1 to 3 In some embodiments, each of the ribs 102 is arranged along a predetermined direction, and the predetermined direction is staggered with the axial direction of the pin. The length direction of the rib 102 has an angle with the plane determined by the end ring 101, and the angle is less than ninety degrees, that is, each rib 102 is tilted relative to the end ring 101.

[0049] Optionally, the design of arranging the ribs 102 along the axial direction of the pin or obliquely arranging them along a predetermined direction provides a flexible arrangement that can be adjusted according to different connectors and application scenarios.

[0050] See also Figures 1 to 3 In some embodiments, the electrical contact surface 1023 is configured as a concave arc surface, and the side surface of the pin is configured as a convex arc surface.

[0051] Optionally, the electrical contact surface 1023 is a concave arc surface, which can form a larger contact area with the peripheral side surface of the pin, thereby helping to reduce contact resistance, improve current transmission efficiency, and ensure stable electrical performance.

[0052] The concave arc-shaped electrical contact surface 1023 can effectively disperse the mechanical friction during plugging and unplugging, reduce local wear, improve the durability of the rib 102, and extend the service life of the entire connector.

[0053] See also Figures 1 to 3 In some embodiments, the end ring 101 includes a ring body 1011 and an electrical connection protrusion 1012 provided on the ring body 1011 , and the electrical connection protrusion 1012 is located on the outer surface of the ring body 1011 .

[0054] Optionally, the height of the electrical bump may be 0.1 mm.

[0055] Optionally, the electrical connection protrusion 1012 on the ring body 1011 can contact the hole wall of the receiving hole when the spring 100 is placed in the receiving hole of the housing, so that the end ring 101 maintains good electrical contact with the housing.

[0056] The electrical contact protrusion 1012 increases the contact points between the end ring 101 and the housing, thereby preventing the spring 100 from being displaced when the connector is subjected to external vibration, thereby improving the vibration resistance of the overall structure.

[0057] See also Figures 1 to 3 In some embodiments, a plurality of the electrical connection protrusions 1012 are arranged at intervals along the circumference of the ring body 1011 .

[0058] Optionally, a plurality of electrical connection protrusions 1012 are arranged at intervals along the circumference of the ring body 1011 to ensure that the end ring 101 forms electrical contact with the housing at multiple points, thereby providing more uniform electrical connection.

[0059] See also Figures 1 to 3 In some embodiments, the electrical connection protrusions 1012 are arranged in sequence at equal intervals.

[0060] Optionally, the electrical connection protrusions 1012 are arranged at equal intervals to ensure that the electrical connection protrusions 1012 are evenly stressed during the plugging and unplugging process, thereby avoiding deformation and wear caused by excessive local stress, ensuring smooth plugging and unplugging, and improving the durability and stability of the reed 100.

[0061] It is understood that after the spring 100 is assembled to the housing hole, since the electrical contact bumps and the housing are made of copper alloy, which has a certain hardness and elasticity, the end ring 101 and the housing hole have an interference fit, so that through extrusion, each electrical contact bump undergoes elastic deformation and forms a thin film effect, so that each electrical contact bump can form a continuous contact with the wall of the housing hole after assembly, that is, the entire outer surface of the end ring 101 is in contact with the wall of the housing hole.

[0062] See also Figure 4It can also be understood that by setting the electrical contact bumps, the outer diameter of the ring body 1011 is increased. After the ring body 1011 is assembled into the receiving hole, the ring body 1011 can produce a greater elastic deformation, thereby increasing the pressure applied to the electrical contact bumps. The greater the pressure at the contact point per unit area, the smaller the contact resistance between the electrical contact bumps and the wall of the receiving hole.

[0063] See also Figure 5 The reed 100 can be formed by stamping a copper alloy plate into the shapes of the ribs 102 and the electrical bumps 1012 , and then bending the copper alloy plate to form the reed 100 .

[0064] See also Figure 4 The present invention also proposes a connector, which includes a reed 100. The specific structure of the reed 100 refers to the above embodiment. Since the reed 100 adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0065] See also Figures 2 to 4 In some embodiments, the connector further includes a shell and a pin, the shell having a receiving hole, the reed 100 is disposed in the receiving hole, and the pin is detachably inserted into the reed 100 .

[0066] Optionally, through the combination of the reed 100, the housing and the pin, the entire connector can provide an efficient and stable electrical connection. The surface-to-surface contact between the reed 100 and the pin effectively reduces the contact resistance and improves the reliability and anti-plugging performance of the electrical connection.

[0067] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
