Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a conductive connector and a connector terminal. Background Technology

[0002] In the field of charging docks, a drum spring structure is usually added to the connection terminal. In the existing technology, some solutions adopt the assembly method of directly fitting the drum spring onto the surface of the connection terminal. Although this method has the advantages of simple structure and convenient assembly, it has obvious defects: the connection area between the drum spring and the connection terminal is small. In the case of transportation and handling, the drum spring is prone to vibration due to bumps and collisions, which may cause the drum spring to fall off the connection terminal.

The channel is opened along the axial direction of the conductive element, and the multiple limiting holes are spaced apart on the outer surface of the conductive element. The connecting element includes a first fixing plate, a second fixing plate, multiple contact plates, and multiple limiting claws. The first fixing plate and the second fixing plate are both sleeved on the conductive element. The two ends of the contact plates are respectively connected to the first fixing plate and the second fixing plate, and the contact plates protrude from the first fixing plate and the second fixing plate in a direction away from the conductive element. The multiple contact plates are spaced apart, and the multiple limiting claws are respectively connected to the first fixing plate and the second fixing plate, and the multiple limiting claws are movably disposed in the multiple limiting holes. The limiting claw has a guide slope, which is opened towards the center of the connecting member.

[0005] According to one embodiment of the present invention, the connecting member has a notch, and multiple limiting claws are located at the notch.

[0006] According to one embodiment of the present invention, the conductive element includes a conductor and a plurality of spring pieces. The conductor has a channel, and the plurality of spring pieces are arranged at intervals around one end of the conductor. A first fixing piece and a second fixing piece are both sleeved on the outside of the conductor.

[0007] According to one embodiment of the present invention, the conductive component has a first supporting curved surface, and a first fixing piece and a second fixing piece are both sleeved on the outside of the first supporting curved surface.

[0008] According to one embodiment of the present invention, the conductive component further includes a first limiting block and a second limiting block disposed on the first supporting curved surface. The first limiting block is located on the side of the first fixing piece away from the second fixing piece, and the second limiting block is located on the side of the second fixing piece away from the first fixing piece.

[0009] The present invention discloses a connection terminal, including the aforementioned conductive connector, sealing element, and assembly. The sealing element is sleeved on the conductive element and blocks the communication between the channels on both sides of the sealing element. The assembly is sleeved on the outside of the conductive element.

[0010] According to one embodiment of the present invention, the assembly includes a sleeve, multiple support plates and multiple first limiting plates. The conductive element has a second supporting curved surface. The sleeve is sleeved on the second supporting curved surface and the outer surface of the multiple spring plates. The sleeve has multiple spaced-apart first through holes. The multiple support plates are respectively disposed in the multiple first through holes. The multiple support plates abut against the multiple spring plates respectively.

[0013] According to one embodiment of the present invention, there are two second through holes, which are disposed opposite to each other on the conductor and the second support surface.

[0014] The beneficial effect of this utility model is that, by setting the guide slope of the limiting claw, the connecting component can be installed more smoothly when assembling the connecting component and the conductive component.

[0017] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model.

[0019] Example 1 like Figures 1-5 As shown, Figure 1 A three-dimensional structural diagram of a conductive connector; Figure 2 This is a schematic diagram of another three-dimensional structure of a conductive connector; Figure 3 This is a schematic diagram showing the disassembled structure of the conductive connector; Figure 4 A three-dimensional structural diagram of the connecting component 2; Figure 5This is a top view of the connector 2. The conductive connector includes a conductive element 1 and a connector 2, with the connector 2 sleeved on the outer surface of the conductive element 1. The conductive element 1 has a channel 11, which is opened along the axial direction of the conductive element 1. External pins and cables can be inserted into the channel 11 and come into contact with the conductive element 1.

[0020] The conductive component 1 includes a conductor 12 and multiple spring contacts 13. A channel 11 is formed in the conductor 12, and the multiple spring contacts 13 are spaced apart at one end of the conductor 12. The connecting component 2 is sleeved on the end of the conductor 12 away from the spring contacts 13. Specifically, after the multiple spring contacts 13 are spaced apart along the edge of the end of the conductor 12, the multiple spring contacts 13 together form a socket (not shown in the figure). The socket communicates with the channel 11. The external pin is first inserted into the socket, and then inserted into the channel 11 from the socket. The multiple spring contacts 13 abut against the external pin, improving the connection effect between the conductive connector and the external pin, thereby ensuring the smooth conduction of current.

[0021] The conductive element 1 has a first supporting curved surface 14, which is disposed on the upper part of the channel 11 and located at the end of the conductor 12. The connecting element 2 is sleeved on the outside of the first supporting curved surface 14 and the conductor 12. In this embodiment, the conductor 12, multiple spring pieces 13, and the first supporting curved surface 14 are an integral structure. In practice, the conductive element 1 is integrally formed by a stamping process, and then the conductive element 1 is rolled up to obtain the corresponding structure.

[0022] The connecting element 2 includes a first fixing piece 21, a second fixing piece 22, and multiple contact pieces 23. The first fixing piece 21 and the second fixing piece 22 are both sleeved on the outside of the first supporting curved surface 14 and the conductor 12. The multiple contact pieces 23 are spaced apart between the first fixing piece 21 and the second fixing piece 22, and both ends of the contact pieces 23 are connected to the first fixing piece 21 and the second fixing piece 22, respectively. Specifically, the contact pieces 23 gradually protrude from their ends towards the center, moving away from the conductor 12. In other words, the outer diameter of the circle formed by the multiple contact pieces 23 is larger than the outer diameter of the circle formed by the first fixing piece 21 and / or the second fixing piece 22. In use, the multiple contact pieces 23 abut against the holes in the circuit board, enabling connection and current conduction.

[0023] The connector 2 also includes multiple limiting claws 25, which are respectively connected to the first fixing plate 21 and the second fixing plate 22. The limiting claws 25 extend towards the center of the circle formed by the first fixing plate 21, the second fixing plate 22, or the multiple contact plates 23. Each limiting claw 25 also has a guide slope 251 located on its outer surface. During the installation of the connector 2 onto the conductive component 1, the guide slope 251 contacts the first supporting curved surface 14 and slides along the outer surface of the first supporting curved surface 14, thereby causing the entire connector 2 to expand and contract outwards, ultimately fitting onto the outer surface of the first supporting curved surface 14. The guide slope 251 provides a guiding effect for the installation of the connector 2, reducing the resistance during installation between the connector 2 and the conductive component 1. In this embodiment, there are four limiting claws 25. One limiting claw 25 is connected to each end of the first fixing plate 21, and one limiting claw 25 is connected to each end of the second fixing plate 22.

[0024] Furthermore, the connector 2 also has a notch 24, which is opened along the axial direction of the connector 2, and multiple limiting claws 25 are located in the area of ​​the notch 24. In this embodiment, the first fixing piece 21, the second fixing piece 22, and multiple contact pieces 23 are all made by stamping. After being made, they are rolled up to form the corresponding structure. During the rolling process, the connector 2 is not a closed structure. Taking the first fixing piece 21 as an example, when the first fixing piece 21 is rolled up, there is a gap between the two ends of the first fixing piece 21; similarly, there is also a gap between the two ends of the second fixing piece 22. The gaps between the first fixing piece 21 and the second fixing piece 22 are axially connected, thus forming the notch 24. The notch 24 facilitates the installation and disassembly of the connector 2 and the conductive piece 1. In this embodiment, the connector 2 is made entirely of a material with high conductivity and high yield strength.

[0025] To further explain, since the limiting claw 25 is provided with a guide slope 251, the radial dimension of the notch 24 can be made smaller, thereby increasing the contact area between the connector 2 and the first support curved surface 14 after they are fitted together. In other words, the connector 2 will fit more tightly with the first support curved surface 14, which helps to prevent the connector 2 from easily falling off the first support curved surface 14.

[0026] Correspondingly, the first supporting curved surface 14 has multiple limiting holes 16, which are spaced apart. When the connecting member 2 is fitted onto the first supporting curved surface 14, multiple limiting claws 25 are respectively located within the multiple limiting holes 16, and the limiting claws 25 can move within a certain range within the limiting holes 16. Through the cooperation of the limiting claws 25 and the limiting holes 16, the connecting member 2 can be further limited, preventing the connecting member 2 from having large-scale linear movement in the axial direction. At the same time, it can also limit the large-scale rotation of the connecting member 2 relative to the conductive member 1, further improving the connection stability between the connecting member 2 and the conductive member 1. In this embodiment, the number of limiting holes 16 is the same as the number of limiting claws 25, that is, the number of limiting holes 16 is four. The limiting holes 16 communicate with the channel 11.

[0027] Preferably, the conductive element 1 further includes a first limiting block 17, which is located on the outer surface of the first supporting curved surface 14. The first limiting block 17 is disposed on the side of the first fixing piece 21 away from the second fixing piece 22, and restricts the movement of the connecting piece 2 away from the second fixing piece 22. Specifically, there are multiple first limiting blocks 17, which are spaced apart and limit multiple areas of the first fixing piece 21. Furthermore, the conductive element 1 also includes a second limiting block 18, which is located on the outer surface of the first supporting curved surface 14. The second limiting block 18 is disposed on the side of the second fixing piece 22 away from the first fixing piece 21, and restricts the movement of the connecting piece 2 away from the first fixing piece 21. Specifically, the second limiting block 18 is opened circumferentially along the first supporting curved surface 14 to increase the contact area with the second fixing piece 22, thereby achieving a better limiting effect.

[0028] In practical applications, the connecting element 2 is made of a material with high conductivity and high yield strength, such as copper.

[0029] In summary, by setting the guide slope 251 of the limiting claw 25, the connector 2 can be installed more smoothly when it is assembled with the conductive component 1. Based on this, the connection area between the connector 2 and the conductive component 1 can be increased, thereby making the connection between the connector 2 and the conductive component 1 more stable and preventing the connector 2 from easily detaching from the conductive component 1. If a traditional structure is used, if the contact area between the connector 2 and the conductive component 1 is increased, it will be impossible to press the connector 2 into the outer surface of the conductive component 1 during assembly.

[0030] Example 2 like Figure 6 and Figure 7 As shown, Figure 6 This is a three-dimensional structural diagram of the connecting terminals; Figure 7This is a cross-sectional view of the connection terminal. The connection terminal includes a conductive connector, a sealing element 3 disposed on the conductive connector, and an assembly 4. The conductive connector adopts the structure in Embodiment 1, which will not be described again. The structure described in Embodiment 1 will be directly referenced below. The sealing element 3 is used to prevent external liquid from flowing into the interior, thus avoiding short circuits in the product; the assembly 4 acts on the conductive element 1, providing a certain degree of support for the conductive element 1.

[0031] In practical applications, the conductive element 1 also has a second supporting curved surface 15. Both the first supporting curved surface 14 and the second supporting curved surface 15 are located on the upper part of the channel 11. The first supporting curved surface 14 and the second supporting curved surface 15 are located at the two ends of the conductor 12, respectively. The fitting 4 is sleeved on the outside of the second supporting curved surface 15 and the multiple spring pieces 13. The sealing element 3 is located between the first supporting curved surface 14 and the second supporting curved surface 15. In this embodiment, the conductor 12, the multiple spring pieces 13, the first supporting curved surface 14, and the second supporting curved surface 15 are an integral structure. In practice, the conductive element 1 is integrally formed by a stamping process, and then the conductive element 1 is rolled up to obtain the corresponding structure.

[0032] The sealing element 3 is fitted over the conductor 12 and also fills a portion of the channel 11. This effectively blocks the channels 11 on both sides of the sealing element 3, preventing external liquid from flowing into the interior and causing a short circuit. In this embodiment, the sealing element 3 is formed using injection molding. This means that the fluid-state sealing element 3 is injected into the channel 11 and the outer surface of the conductor 12 through injection molding. After the fluid-state sealing element 3 cools and solidifies, it forms a structure that encloses the conductor 12 and fills the channel 11.

[0033] The assembly 4 includes a sleeve 41, multiple support plates 42, and multiple first limiting plates 43. The sleeve 41 is sleeved on the outside of the conductor 12, the second supporting curved surface 15, and multiple spring pieces 13. The sleeve 41 has multiple spaced first through holes 411. The multiple support plates 42 are respectively disposed in the multiple first through holes 411, and the multiple support plates 42 abut against the multiple spring pieces 13. The support plates 42 provide support for the spring pieces 13. When the external pin is inserted, the supporting force of the support plates 42 on the spring pieces 13 can effectively increase the positive force between the spring pieces 13 and the external pin, thereby improving the current conduction effect between the two. In addition, the support of the spring pieces 13 by the support plates 42 can effectively prevent the spring pieces 13 from being easily crushed, thereby extending the service life of the spring pieces 13. Multiple first limiting pieces 43 are spaced apart at one end of the sleeve 41 away from the connecting member 2. The first limiting pieces 43 are hooked inward to the spring piece 13. Specifically, the first limiting pieces 43 are bent inward and abut against the inner wall surface of the spring piece 13.

[0034] Furthermore, the second supporting curved surface 15 has a second through hole 151 communicating with the channel 11. The assembly 4 also includes a second limiting piece 44, which passes through the second through hole 151 and abuts against the inner wall of the channel 11. That is, the second limiting piece 44 extends into the channel 11 through the second through hole 151, then bends and abuts against the inner wall of the channel 11. Specifically, there are two second limiting pieces 44, which are symmetrically arranged and located on opposite sides of the second through hole 151. Preferably, there are two second through holes 151, which are opposite to each other, and each second through hole 151 contains two corresponding second limiting pieces 44. In this embodiment, one second through hole 151 is located on the second supporting curved surface 15, and the other second through hole 151 is located on the conductor 12. The cooperation between the second limiting piece 44 and the second through hole 151 can further improve the fixing effect of the assembly 4.
