The terms used herein in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0054] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the embodiments and features in the following embodiments can be combined with each other.

[0055] Embodiment 1

[0056] First, refer to Figure 2 , Figure 3 and Figure 4 to describe the structural schematic diagram of the conductive terminal according to the embodiment of the present application.

[0057] AsFigure 2 As shown, the main body of the conductive terminal 100 for an electrical connector is a 90-degree elbow terminal structure, and the conductive terminal includes a first conductive member and a second conductive member. Among them, the first conductive member is an integral structure formed by stamping a metal pipe. The first conductive member has a flat portion and a tubular portion arranged at the head and tail. The flat portion is a stamping structure formed by stamping at the end of the pipe of the first conductive member, and the second conductive member is welded to the flat portion of the first conductive member.

[0058] In this embodiment, the first conductive member and the second conductive member are used as the conductive connection components of the electrical connector, and they are made of metal materials, such as metal materials like copper and copper alloys, aluminum alloys, etc. The present utility model does not limit the specific materials of the conductive terminal.

[0059] It should be noted that the first conductive member is a round pipe when it comes in, which is a kind of metal pipe. It is preferably an extruded metal pipe. Extrusion molding is to heat and melt the material and then extrude it through a mold. This type of metal pipe also does not require machining and does not waste raw materials. A drawn metal pipe can also be used.

[0060] Among them, the flat portion 111 is a stamping structure formed by stamping at the end of the metal pipe of the first conductive member. The flat portion of the first conductive member is configured as a structural part for welding the second conductive member, and the second conductive member is welded on the outer surface of the flat portion.

[0061] It should be noted that as Figure 4 shown, the first conductive member is divided into a head end and a tail end along its own length direction. The head end of the first conductive member forms a flat end through a stamping process.

[0062] In the well-known technology in this field, stamping is a metal processing method. By using a mold on a punching press and applying pressure to the metal material, plastic deformation is generated to obtain a workpiece with the required shape and size. The stamping process has the advantages of high production efficiency, low cost, and stable quality, so it is widely used in industrial production. The flat portion of the first conductive member in this embodiment is formed by stamping, and it does not require a large amount of copper column material to be cut by the cutting process in the prior art, improving the material utilization rate.

[0063] In a specific implementation, the flat portion of the first conductive member may be provided with a stamping groove, and the stamping groove does not penetrate the flat portion. The second conductive member can be embedded in the stamping groove for welding to improve the welding stability.

[0064] In a preferred implementation, the tubular portion is a tubular structure formed by expanding the diameter of a partial pipe of the first conductive member; alternatively, the tubular portion is a tubular structure formed by expanding the diameter of a partial pipe of the first conductive member, and an external thread is provided on the outer peripheral surface of the tubular portion.

[0065] In one example, Figure 8 As shown, the external thread of the tubular portion is used for connection, and the first conductive member can be threadedly connected to other conductive components in the electrical connector. On the other hand, the external thread of the tubular portion can also be used for installation and assembly, and the first conductive member can be threadedly connected to the threaded installation structure of the electrical connector.

[0066] The tubular portion 112 is a tubular structure formed by expanding the diameter of a local tube of the first conductive member 110. The tubular portion of the first conductive member is configured to be used in a manner similar to a socket terminal in the art. Specifically, the tubular portion of the first conductive member is equivalent to a socket structure of a socket terminal, and can be used to plug and connect a pin terminal in the art, or other electrical connection components adapted for plugging, to achieve electrical connection.

[0067] It should be noted that if Figure 4 As shown, the local tube at the end of the first conductive member 110 is expanded through a diameter expansion process to form a tubular end portion having an outer diameter greater than the original outer diameter of the tube of the first conductive member itself.

[0068] In the known technology in this field, diameter expansion refers to a process of increasing the local diameter of a pipe by mechanical processing. There are two main types of diameter expansion processes: mechanical diameter expansion and hydraulic diameter expansion. Mechanical diameter expansion is the expansion of a pipe by using a special mechanical tool, such as an expander or an expansion die. Hydraulic diameter expansion is the expansion of a pipe by using the pressure generated by a hydraulic device. The diameter expansion process usually causes a significant change in the diameter of the pipe, which can be judged by the following appearance characteristics: (1) Diameter change: The diameter of the expanded part is usually larger than that of other parts, and there may be obvious expansion marks at the transition point. (2) Pipe wall thickness: During the diameter expansion process, the wall thickness of the expanded part may change, and the wall thickness of the expanded part may be slightly thinner than that of the non-expanded part. Ultrasonic detection can be used: Ultrasonic waves can detect changes in the internal structure of the material, and the expanded part may have different sound wave reflection characteristics due to deformation.

[0069] The tubular portion 112 of the conductive terminal 100 of the present embodiment is a tubular structure formed by expanding the diameter of a local tubular material of the first conductive member 110. The conductive terminal structure has a high material utilization rate. The diameter expansion process can maximize the use of raw materials during the processing process and reduce the generation of waste, thereby improving material utilization and ensuring the integrity of the structure. The diameter expansion process allows the tubular portion to be uniformly deformed: the diameter expansion process allows the tube to be uniformly stressed during the diameter expansion process, which can effectively avoid stress concentration and improve the mechanical properties of the tubular portion. The flat portion is formed by stamping, and does not require the use of a large amount of copper column material by cutting technology in the prior art, thereby improving the material utilization rate.

[0070] Based on the above description, it can be understood that by respectively stamping and expanding the diameters of the head and tail end portions of the first conductive member of a metal pipe structure, the flat portion and the tubular portion of the first conductive member are joined into an integral structure through the original part of the pipe of the first conductive member. The width of the flat portion is greater than the outer diameter of the pipe of the first conductive member, and the outer diameter of the tubular portion is greater than the outer diameter of the original pipe of the first conductive member.

[0071] The main body of the conductive terminal of the present utility model is a first conductive member 110. By using a pipe structure, it is not necessary to adopt processes such as cutting to generate waste materials, thereby improving the material utilization rate and saving manufacturing costs. Through the flat portion formed by stamping at the pipe end of the first conductive member, this stamping structure is used for the connection of wires. The flat portion of the present invention does not need to be formed by a large amount of cutting of copper column materials in the prior art. Through the tubular structure formed by expanding the diameter of a local pipe of the first conductive member, the tubular portion formed by the diameter expansion process can be processed and produced using a first conductive member with a smaller outer diameter to obtain the required specifications and dimensions, relatively reducing the manufacturing materials.

[0072] The present utility model adopts the first conductive member 110, combines the stamping structure formed by stamping the first conductive member and the tubular structure formed by expanding the diameter of the first conductive member, and finally forms a conductive terminal structure, which can greatly reduce the manufacturing materials, and there is no cutting waste, improving the material utilization rate. This cannot be achieved by the terminal structure of the existing electrical connectors.

[0073] In a specific implementation, the second conductive member is a metal pipe structure or a stamping structure formed by stamping a metal pipe.

[0074] Among them, the second conductive member has a tubular connecting portion, and the second conductive member is welded to the outer surface of the flat portion of the first conductive member through the tubular connecting portion; among them, the first conductive member and the second conductive member are fixedly connected by high-frequency welding, ultrasonic welding or laser welding.

[0075] It can be understood that the second conductive member has a tubular end portion, and this tubular end portion is specifically used for welding the first conductive member. Specifically, the axis of the tubular connecting portion of the second conductive member is perpendicular to the outer surface of the flat portion of the first conductive member, and the second conductive member and the first conductive member are welded to form a conductive terminal with a ninety-degree elbow structure.

[0076] In the specific implementation technology of the present utility model, regarding the second conductive member, this patent provides two specific implementation manners:

[0077] In the first implementation, the second conductive member 120 is a metal pipe structure. It can be understood that when the second conductive member comes in, it is a hollow circular pipe with both ends penetrating, which is a kind of metal pipe.

[0078] Specifically, such as Figure 5 、Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 A second conductive member structure as shown. The second conductive member is an overall hollow circular tube structure that penetrates through both ends. Specifically, the second conductive member has an upper end portion 121 and a lower end portion 122. The upper end portion of the second conductive member is a tubular connection portion for welding to the flat portion of the first conductive member.

[0079] In a specific implementation, as Figure 7 shown, an external thread is provided on the outer peripheral surface of the lower end portion of the second conductive member.

[0080] In one example, the external thread on the lower end portion of the second conductive member is for connection, and the second conductive member can be threadedly connected to other conductive components in the electrical connector. On the other hand, the external thread on the lower end portion of the second conductive member can also be used for installation and assembly, and the conductive terminal can be threadedly connected to the threaded installation structure of the electrical connector through the second conductive member.

[0081] In another specific implementation, as Figure 5 and Figure 6 shown, the lower end portion of the second conductive member is a tubular structure formed by locally expanding the diameter of the second conductive member's pipe.

[0082] In one example, the lower end portion of the second conductive member is a tubular structure, which is configured to be used in a manner similar to a jack terminal in the art. Specifically, the lower end portion of the second conductive member is equivalent to the jack structure of the jack terminal, and the tubular structure can be used to plug and connect a pin terminal in the art, or other electrically connected components suitable for plugging, to achieve electrical connection.

[0083] In the well-known technology in the art, diameter expansion refers to a process of increasing the local diameter of a pipe through mechanical processing methods. There are mainly two ways of diameter expansion process: mechanical diameter expansion and hydraulic diameter expansion. Mechanical diameter expansion is to expand the pipe by using special mechanical tools, such as a diameter expander or a diameter expansion die. Hydraulic diameter expansion is to expand the pipe by using the pressure generated by a hydraulic device.

[0084] In a specific application scenario, the wire can be inserted into the tubular structure of the lower end portion of the second conductive member, and the second conductive member can be fixedly connected to the wire by means of pressing or welding.

[0085] In another specific implementation, as Figure 9 and Figure 10 shown, a crown spring is connected inside the cavity of the second conductive member, and the crown spring inside the cavity is exposed at the lower end opening of the second conductive member.

[0086] In one example, the lower end portion of the second conductive member is a tubular structure, which is configured to be used in a manner similar to a jack terminal in the art. Specifically, the lower end portion of the second conductive member is equivalent to the jack structure of the jack terminal, and the tubular structure can be used to plug and connect a pin terminal in the art, or other electrical connection members adapted for plugging, so as to achieve electrical connection.

[0087] In the technical field of electrical connectors, there is a type of electrical connector in which a crown spring is provided in the jack of the electrical connector, and the conductive connection between the jack of the electrical connector and the pin terminal is achieved by using the crown spring. In the present technology, a crown spring is provided at the lower end portion of the second conductive member. The crown spring is generally formed in a cylindrical shape, and rectangular spring pieces are provided between the connection bands at both ends thereof. And, a convex contact point is formed at the middle portion of the spring piece, facing the inner axis of the cylinder, and electrical contact with the pin terminal is made through these contact points to play a role in conducting the circuit.

[0088] In the second embodiment, as Figure 2 、 Figure 3 shown, the second conductive member is a stamping structure formed by stamping a metal pipe.

[0089] Specifically, the upper end portion of the second conductive member is a tubular structure, and the upper end portion of the second conductive member is welded to the outer surface of the flat portion of the first conductive member; the lower end portion of the second conductive member is flat, and the lower end portion of the second conductive member is a stamping structure formed by stamping the pipe end of the second conductive member. Specifically, the lower end portion of the second conductive member is used for electrical connection.

[0090] It should be noted that the tubular connection portion is a part of the original metal pipe, and the lower end portion is a flat plate-like structure formed by stamping and deforming a partial pipe of the metal pipe. It can be understood that the second conductive member in this embodiment is a circular pipe when it comes in, which is a kind of metal pipe, and can be made by stamping a part of the circular pipe.

[0091] In the electrical connection application scenario of the conductive terminal, the lower end portion of the second conductive member can be used to connect other components in the electrical connector, such as wires and cables to achieve electrical connection, and the lower end portion of the second conductive member can also be used as a structural part for fixedly installing the conductive terminal in the electrical connector.

[0092] In the specific application scenarios of the installation and electrical connection of the electrical connector, a perforation structure is provided at the lower end portion of the second conductive member, and the perforation structure is configured to be an installation structure for fixedly connecting other components by the conductive terminal. In other embodiments, such as Figure 11 、 Figure 12As shown, a perforation structure is provided at the lower end of the second conductive member. The conductive terminal includes a riveting nut 140, and the riveting nut is riveted and fixed in the perforation structure at the lower end of the second conductive member. The threaded hole of the riveting nut facilitates the use and fixation of the conductive terminal, etc.

[0093] In the above specific implementation, the first conductive member is an integral structure formed by stamping a metal pipe, and the second conductive member is a metal pipe structure or a stamping structure formed by stamping a metal pipe; wherein, the wall thickness of the pipes of the first conductive member and the second conductive member is 1-10 mm.

[0094] This embodiment also provides a first type of electrical connector, and the electrical connector includes the above-mentioned conductive terminal.

[0095] In the present utility model, an electric connector is a device for realizing electrical connection and disconnection, and is widely used in various electronic devices and systems. Its main function is to provide a pluggable connection point for signal transmission and power supply. There are various types of electric connectors, which can be divided into multiple types according to different application scenarios, structural forms and functional requirements. For example, vehicle connectors in the electrical architecture of new energy vehicles, as well as energy storage connectors for photovoltaic power generation systems, grid energy storage systems, and charging piles.

[0096] In this field, it is a special connector for the electrical systems of electric vehicles (EV) and hybrid electric vehicles (HEV). These connectors are used to connect power batteries, charging devices, electric motors and various control modules to ensure efficient transmission of power and signals. Due to the special requirements of new energy vehicles, these connectors need to have higher electrical performance, safety and environmental adaptability. An energy storage connector is an electric connector specifically designed for energy storage systems, and is usually applied to battery systems, renewable energy systems such as solar energy and wind energy, and other devices that require electrical energy storage and conversion. Energy storage connectors play a key role in these systems to ensure efficient transmission of electrical energy, safe connection and reliable operation of the system.

[0097] The electric connector defined by the present utility model may also be an electric connector used in other industries, and is not limited to the above-mentioned electric connector.

[0098] For other structures of the conductive terminal and the electrical connector in this embodiment, refer to the prior art.

[0099] The above are only preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Therefore, any modifications, equivalent changes and decorations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the scope of the technical solution of the present utility model.
