Description

[0001] The utility model relates to the technical field of electrical connectors, and particularly relates to a conductive terminal, an electrical connection assembly and an electrical connector. Background Art

[0002] Electrical connectors are widely used in various industrial fields, such as vehicle connectors in automotive electronic and electrical architectures, and energy storage connectors for photovoltaic power generation systems, grid energy storage systems, and charging piles. An electrical connector generally includes a plastic housing and terminals installed in the housing. After the terminals are inserted into the housing, the front and rear ends are respectively electrically connected to other conductors through appropriate wiring techniques (for example, the front end of the terminal is inserted into a mating terminal, and the rear end of the terminal is crimped to a wire or connected by bolts).

[0003] Taking the terminal structure of an energy storage connector as an example, it generally includes a pin terminal 1 and a jack terminal 2 that are inserted into each other. Figure 1A Shows a pin terminal and its processing schematic diagram. Figure 1B Shows a jack terminal. In an application scenario of an electrical connector, the column structure ( Figure 1A the cylindrical end in ) of the plug-in terminal 1 can be inserted into the jack structure 21 of the jack terminal 2 for establishing an electrical connection.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein 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.

[0065] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0066] Embodiment 1

[0067] First, refer to Figure 2 、 Figure 3 and Figure 4 to describe the schematic structural diagram of the conductive terminal according to the embodiment of the present application.

[0068] As Figure 2 shown, the main body of the conductive terminal 100 for an electrical connector is a pipe, and the conductive terminal includes a sleeve 110. The sleeve has a flat portion 111 and a tubular portion 112 arranged at the head and tail.

[0069] In this embodiment, the sleeve 110 is used as the conductive connection member of the electrical connector, and it is made of a conductive metal material, such as metal materials such as copper and copper alloys, aluminum alloys, etc. The present invention does not limit the specific material of the conductive terminal.

[0070] It should be noted that the sleeve is a round pipe when it comes in, which is a metal pipe. It is preferably an extruded metal pipe, and extrusion molding is to extrude the material through a mold after heating and melting it. This type of metal pipe also does not require machining and does not waste raw materials. It is also possible to use a drawn metal pipe.

[0071] Among them, the flat part 111 is a stamping structure formed by stamping the end of the pipe of the sleeve, and the flat part of the sleeve is configured to be used in a manner similar to the flat end of the pin terminal 1 shown in Figure 1A Specifically, the flat part of the conductive terminal can be used to connect other components in the electrical connector, such as wires and cables, to achieve electrical connection. The flat part can also be used as a structural part for fixedly installing the electrical connector.

[0072] It should be noted that, as Figure 2 shown, the sleeve is divided into a first end and a second end along its own length direction. The first end of the sleeve forms a flat end through a stamping process.

[0073] In the well-known technology in this field, stamping is a metal processing method. By using a die on a punching press to apply pressure to a 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 has been widely used in industrial production. The flat part of the conductive terminal 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.

[0074] In a specific implementation, the flat part of the sleeve has a perforation for installation and connection. The perforation can be connected to other components or fixedly installed the conductive terminal through a bolt connection method.

[0075] In a preferred implementation, the conductive terminal further includes a riveting nut 130, and the riveting nut is riveted to the riveting hole opened in the flat part. The threaded hole of the riveting nut facilitates the use and fixation of the sleeve, etc.

[0076] Among them, the tubular part 112 is a tubular structure formed by expanding the diameter of a local pipe of the sleeve 110. The tubular part of the sleeve is configured to be used in a manner similar to the jack terminal 2 shown in Figure 1B Specifically, the tubular part of the conductive terminal is equivalent to the jack structure 21 of the jack terminal 2. The tubular part of the conductive terminal can be used to connect Figure 1A the pin terminal in, or other electrically connected components suitable for plugging and connecting, to achieve electrical connection.

[0077] It should be noted that, as Figure 4 shown, the local pipe at the second end of the sleeve forms a tubular end with an outer diameter larger than the sleeve itself through a diameter expansion process.

[0078] 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.

[0079] 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 sleeve 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 material utilization.

[0080] Based on the above description, it can be understood that by punching and expanding the ends of a sleeve of a tubular structure, the flat portion and the tubular portion of the sleeve are connected to form an integral structure through the original part of the sleeve. The width of the flat portion is greater than the outer diameter of the sleeve tube, and the outer diameter of the tubular portion is greater than the outer diameter of the sleeve tube.

[0081] The main body of the conductive terminal of the utility model is a sleeve 110, which uses a tubular structure and does not need to use a cutting process to generate waste materials, thereby improving material utilization and saving manufacturing costs. The flat portion is formed by stamping at the end of the sleeve tube. The stamping structure is used for connecting the wires. The flat portion of the present invention does not need to be formed by cutting a large amount of copper column material using a cutting process in the prior art. The tubular structure is formed by expanding the diameter of a part of the sleeve tube. The tubular portion formed by the expansion process can be processed and produced using a sleeve with a smaller outer diameter to obtain a specification size that meets the requirements, and relatively reduce the manufacturing materials.

[0082] The utility model adopts a sleeve 110, combines a stamping structure formed by stamping the sleeve and a tubular structure formed by expanding the diameter of the sleeve, 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 structures of existing electrical connectors.

[0083] In the first embodiment, the conductive terminal is used to form a jack terminal of an electrical connector through the tubular portion of the sleeve, that is, the conductive terminal can be used as a jack terminal in an electrical connector as shown in Figure 1B . The tubular portion of the conductive terminal is used to mate with and plug into the pin terminal of the electrical connector, and can also be used to mate with and plug into other electrical connection components.

[0084] In a preferred embodiment, as shown in Figure 3 , the conductive terminal 100 includes a crown spring 120, and the crown spring is connected inside the tubular portion of the sleeve.

[0085] In the technical field of electrical connectors, there is a type of electrical connector that sets a crown spring inside the jack of the electrical connector to achieve conductive connection between the jack of the electrical connector and the pin terminal through the use of the crown spring. 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, raised contact points are formed in the middle of the spring pieces and towards 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.

[0086] Embodiment 2

[0087] First, refer to Figure 5 , Figure 6 and Figure 7 to describe the schematic structural diagram of the conductive terminal according to the embodiment of the present application.

[0088] As shown in Figure 5 , the main body of the conductive terminal 110 for an electrical connector is a pipe, and the conductive terminal 100 includes a sleeve 110 and a conductive filling member 130. The sleeve 110 has a flat portion 111 and a tubular portion 112 arranged at the head and tail, and the conductive filling member 130 is connected inside the tubular portion 112 of the sleeve 110.

[0089] In this embodiment, the sleeve 110 and the conductive filling member 130 are electrical connection components of the electrical connector, and they are made of conductive metal materials, such as metal materials such as copper and copper alloys, aluminum alloys, etc. The present utility model does not limit the specific materials of the components of the conductive terminal.

[0090] It should be noted that the sleeve comes in the form of a round tube, which is a kind of metal pipe. Preferably, an extruded metal pipe is used. 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 cutting processing and does not waste raw materials. A drawn metal pipe can also be used.

[0091] Among them, the flat part is a stamping structure formed by stamping at the end of the pipe of the sleeve. The flat part of the sleeve is configured to be used in a manner similar to the flat end of the pin terminal 1 shown, specifically, the flat part of the conductive terminal can be used to connect other components in the electrical connector, such as wires and cables, to achieve electrical connection, and the flat part can also be used as a structural part for fixedly installing the electrical connector. Figure 1A As shown, the sleeve is divided into a first end and a second end along its own length direction. The first end of the sleeve forms a flat end through a stamping process.

[0092] It should be noted that, as Figure 4 shown, the sleeve is divided into a first end and a second end along its own length direction. The first end of the sleeve forms a flat end through a stamping process.

[0093] In the well-known technology in this field, stamping is a metal processing method. By using a mold on a punching press to apply 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 has been widely used in industrial production. The flat part of the conductive terminal in this embodiment is formed by stamping, and it does not require a large amount of cutting of copper column materials using the cutting process in the prior art, improving the material utilization rate.

[0094] In a specific implementation, the flat part of the sleeve 110 has a perforation for installation and connection. The perforation can be connected to other components or fixedly installed on the conductive terminal through bolt connection.

[0095] In a preferred implementation, the conductive terminal 110 further includes a press riveting nut 140, and the press riveting nut is riveted to the riveting hole opened in the flat part. The threaded hole of the press riveting nut facilitates the use and fixation of the sleeve, etc.

[0096] Among them, the tubular part 112 is a tubular structure formed by expanding the diameter of a local pipe of the sleeve. It should be noted that, as Figure 4 shown, the local pipe at the second end of the sleeve forms a tubular end with an outer diameter larger than the sleeve itself through a diameter expansion process.

[0097] In the publicly known technology in this field, 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. The diameter expansion process usually forms an obvious diameter change in a local part of the pipe, which can be judged by the following appearance features: (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. (2) Wall thickness of the pipe: 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 unexpanded part. Ultrasonic detection can be used: Ultrasonic waves can detect changes in the internal structure of materials, and the expanded part may have different acoustic wave reflection characteristics due to deformation.

[0098] In a specific implementation, the outer contour of the conductive filler 130 matches the lumen of the tubular part. The conductive filler is a pipe with a locally filled sleeve, and the length of the conductive filler can match the depth of the lumen of the tubular part to fully fill the entire tubular part. Of course, the length of the conductive filler can be less than the depth of the lumen of the tubular part to locally fill the tubular part.

[0099] In one implementation, the sleeve is generally cylindrical, and the tubular part of the sleeve is tubular with a circular cross-section. At this time, the conductive filler is a matching cylinder.

[0100] Specifically, the present utility model provides the following several ways to realize the assembly connection of the conductive filler in the sleeve:

[0101] In a specific implementation, the conductive filler is in transitional fit with the tubular part of the sleeve, and this transitional fit satisfies that the conductive filler is fastened in the tubular part. Realizing the assembly through transitional fit does not require any external equipment or material connection, and it is not only simple in structure but also low in cost.

[0102] It can be understood that the tolerance control of this transitional fit needs to reach between the sleeve and the conductive filler. Under normal conditions, the filling guide is fastened in the tubular part and will not break away from the sleeve. And under a certain external force, the filling conductive part will not have relative sliding.

[0103] In another specific implementation, the conductive filler is in interference fit with the tubular part of the sleeve.

[0104] In another specific implementation, the conductive filler is threadedly connected or welded to the tubular part of the sleeve.

[0105] In a preferred implementation, as Figure 5As shown, the conductive filler 130 has a threaded hole 131, and the threaded hole of the conductive filler is exposed on the outer surface of the end of the conductive terminal. It can be understood that after the conductive filler is assembled and connected to the sleeve, the conductive filler is exposed on the outer wall of one end of the sleeve, and the threaded hole can be directly observed through the end of the sleeve.

[0106] Among them, the conductive terminal can be threadedly connected to the electrical connector through the threaded hole of the conductive filler. In the installation structure of some electrical connectors, the conductive terminal needs to be fixed inside the electrical connector by bolts.

[0107] In the field of electrical connectors, the pin terminal has multiple usage scenarios. The first is to use the pin (column structure, such as Figure 1A the cylindrical end in) of the pin terminal to be inserted and mated with the jack terminal. Second, a threaded hole is provided at the end of the column structure of the pin terminal to provide an installation structure and is connected to the electrical connector by bolts and used as one of the conductive components of the electrical connector.

[0108] Based on the above description, for the conductive terminal of the second embodiment, the combined structure of the tubular part of the sleeve and the conductive filler is configured to be used in a manner similar to that of the pin terminal 1 shown in Figure 1A . Specifically, the combined structure is equivalent to the pin (column structure, such as Figure 1A the cylindrical end in) of the jack terminal 1. The tubular part of the conductive terminal can be used to connect Figure 1B the jack terminal in, or be fixed in the electrical connector as an installation structure to achieve electrical connection.

[0109] Embodiment Three

[0110] Embodiment Three provides a first electrical connection assembly for an electrical connector. The electrical connection assembly includes the conductive terminal in Embodiment One. The conductive terminal can be used as a kind of jack terminal in the electrical connection assembly and is adaptively inserted with the pin terminal.

[0111] Embodiment Three also provides a second electrical connection assembly for an electrical connector. The electrical connection assembly includes the conductive terminal in Embodiment Two. The conductive terminal can be used as a kind of pin terminal in the electrical connection assembly, can be used as a conductive component adapted to be connected to the jack terminal, and can also be used as a conductive component in the electrical connector.

[0112] This third embodiment also provides a third electrical connection assembly for an electrical connector, the electrical connection assembly includes a pin terminal and a socket terminal, the socket of the socket terminal and the pin of the pin terminal are adapted for plug-in connection. The socket terminal is the conductive terminal in the first embodiment, and the socket of the socket terminal is composed of the tubular portion of the conductive terminal in the first embodiment. The pin terminal is the conductive terminal in the second embodiment, and the pin terminal is composed of the tubular portion of the conductive terminal in the second embodiment and a conductive filler.

[0113] Embodiment 4

[0114] The fourth embodiment provides a fourth electrical connection assembly for an electrical connector, the electrical connection assembly comprising a pin terminal 200 and a socket terminal 300, the socket structure of the socket terminal and the column structure (pin) of the pin terminal being adapted for plug-in connection.

[0115] like Figure 8 As shown, the socket terminal is the conductive terminal described in the first embodiment, the socket terminal has a tubular portion, and the socket structure of the socket terminal is formed by the tubular portion. In a preferred implementation, a crown spring is connected inside the tubular portion.

[0116] like Figure 9 As shown, the pin terminal 200 has an elastic plug-in portion 210, and the pin terminal is used to plug and match with the tubular portion of the socket terminal through the elastic plug-in portion to form an electrical connection between the socket terminal and the pin terminal. The elastic plug-in portion has a plurality of spring pieces 211 distributed along the circumference of the pin terminal.

[0117] In a specific implementation, the end of the spring piece 311 is an outwardly curved structure.

[0118] Specifically, the structural design of the elastic plug-in portion is adopted to ensure that the pin terminal has good elasticity and meets the elasticity requirements. When in use, the elastic plug-in portion of the pin terminal will extend into the plug hole of the socket terminal. When the elastic plug-in portion of the pin terminal begins to pass through the tubular portion of the socket terminal, due to the limitation of the diameter of the lumen of the tubular portion, multiple spring pieces are pressed into the middle by the wall of the lumen and gathered. When the pin terminal is inserted to the depth of the plug-in position, the end of the spring piece forms a radial elastic load with the inner wall of the lumen in the lumen, forming a physical interference. One aspect of this interference is reflected in the restriction or suppression of the shaking, sliding, and separation of the pin terminal.
