Description

Technical Field

[0001] This invention relates to the field of line connection technology, and in particular to a line connection component. Background Technology

[0002] With the development and popularization of new energy vehicles, the innovative design of new energy battery packs and related products has also evolved. During the design, manufacturing, and testing of new energy batteries and related products, frequent connection and disconnection of circuits is required. Furthermore, the circuit connections and tests involved in new energy batteries mostly involve safe voltages that will not harm the human body. However, using traditional wire stripping and wrapping methods for connection and disconnection is cumbersome. Moreover, using insulating tape for stabilization can easily expose the inner core of the wires when pulled, reducing circuit safety and affecting connection stability. Existing connection equipment has low resistance to pulling during use, often requires auxiliary tools, is cumbersome, occupies a large space, has low application flexibility, and results in low circuit connection stability.

[0003] Patent document CN112038819A discloses a quick connection device for electrical engineering circuits, including a male terminal and a female terminal; both the male and female terminals include: an insulation section clamping assembly; a conductive medium section clamping assembly; and a slide assembly for driving the insulation section clamping assembly to clamp the insulation section of the conductor and simultaneously driving the conductive medium section clamping assembly to clamp the conductive medium section; the male terminal also includes: a conductive component A for conducting current in the conductor; the female terminal also includes: a conductive component B for conducting current in the conductor; and a male-female clamping assembly for making electrical contact between the conductive component A and the conductive component B, and for making the male terminal and the female terminal detachably connected.

[0004] It connects lines via male and female terminals, offering fast, safe, and stable connections, and allows for easy connection and disconnection. However, it also has drawbacks: 1. It has a relatively complex structure and high manufacturing costs; 2. It requires male and female terminals to be used together, resulting in multiple production steps; 3. It has a large size and occupies a significant amount of space; 4. It requires additional tools and has poor application flexibility.

[0005] Patent document CN114899660A discloses a quick connection device for electrical engineering circuits, including a device body, a stabilizing component, and a second stabilizing component. Stabilizing components are fixedly connected to the top two sides of the inside of the device body, and second stabilizing components are fixedly connected to the bottom two sides of the inside of the device body. Stabilizing rods are fixedly connected to the front two sides of the device body. A hollow column is fixedly connected to the middle right side of the stabilizing component. A threaded rod is threaded through the middle of the inside of the hollow column. A pressing circular plate is fixedly connected to the middle bottom of the threaded rod. A device wire is movably connected to the bottom of the pressing circular plate. The device wire is pressed and fixed, and then a limiting rod passes through the top of the two threaded rods, and a limiting nut further stabilizes both sides of the limiting rod.

[0006] This design achieves tight wire connections, making the device more stable and facilitating the stabilization of wires of varying thicknesses. The bottom of the base provides stable support for the main body of the device. However, it also has drawbacks: a more complex structure, higher manufacturing costs, the need for male and female components, a larger structural volume, greater space requirements, the need for additional tools, and less application flexibility.

[0007] Therefore, it is evident that in reality, there is a need for a line connection component that is simple in structure, easy to operate, can provide good insulation protection for the connected wires, can be used at both ends of the wire connection, has high application flexibility, occupies little space, requires no additional tools when connecting stripped wires, has strong tensile strength, and improves the stability of the wire connection.

[0042] The embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] like Figure 1-8 As shown, the present invention discloses a line connection assembly 100, including a housing 10, including a wire inlet 11 for wire entry and a cavity 12 for placing a clamping assembly 20; the housing 10 is made of an insulating material, such as insulating plastic, and the housing 10 has sufficient strength to support the clamping assembly 20 placed in the cavity 12.

[0044] The clamping assembly 20 is used to squeeze the stripping feed line entering the cavity 12, so that the stripping feed line contacts the connecting plate 40 and extends into one end of the cavity 12. The side of the clamping assembly 20 that contacts the stripping feed line can be made of a metal material or hard plastic with a certain strength, forming a sufficient compression of the stripping feed line, so that the stripping feed line is in full contact with one end of the connecting plate 40. There are many possible structures for the clamping assembly 20, and the following embodiment 1 introduces one of them.

[0045] The clamping frame 30 is sleeved on the outside of the housing 10, covering the clamping component 20, and is used to fix the position of the clamping component 20 in the housing 10. The clamping frame 30 is made of insulating material and has a certain strength, such as plastic or hard rubber. The clamping frame 30 clamps and fixes the clamping component 20, causing the clamping component 20 to squeeze the stripping wire, so that the stripping wire is in full contact with the connecting plate 40.

[0046] The connecting plate 40 is made of a metal material with a certain strength, such as copper. One end of the connecting plate 40 extends into the cavity 12 and forms an insertion gap with the wall of the cavity 12 for inserting another connecting component 100. The connecting plate 40 is located at the outer end of the housing 10. This invention requires the combined use of two connecting components 100. After one end of the connecting plate 40 of one connecting component 100 is inserted into the other connecting component 100, it makes full contact with the connecting plate 40 of the other connecting component 100, thereby forming an electrical connection between the two connecting components 100. This requires leaving a splicing plate cavity at the connection between the connecting plate 40 and the housing 10, so that the connecting plates 40 of the two connecting components 100 can make contact with each other.

[0047] In use, first prepare the wires, strip the wires at the inlet so that the part of the wire entering the housing 10 is bare wire, and the wires on the outside of the housing 10 have an insulating sheath. The stripped wire enters the cavity 12 through the inlet 11. The bare part is squeezed by the clamping component 20 and makes full contact with the end of the connecting plate 40 located inside the housing 10 to form an electrical connection. The end of the connecting plate 40 located inside the housing 10 forms an insertion gap with the housing 10. A clamping frame 30 is fitted on the outside of the housing 10 and the clamping component 20 to fix the clamping component 20 and maintain a stable connection between the stripped wire and the connecting plate 40. Combine the two connected components 100. The connecting plates 40 of the two connected components 100 are inserted into the pre-reserved splicing plate cavity of each other. The two connecting plates 40 in the splicing plate cavity are in surface contact to realize the electrical connection between the two connected components 100.

[0048] This invention is mainly applicable to environments where safe voltage is used. The exposed connecting plate 40 of the connecting component 100 will not cause harm to the operator. The housing 10 and the clamping frame 30 are made of insulating material, which can form good insulation protection for the connected wires and prevent short circuits.

[0049] The connecting component 100 adopts a symmetrical structure, and the same connecting component 100 can be used at both ends of the wire connection. Compared with the connection combination of male and female parts, it can reduce the production process and improve the application flexibility of the connecting component 100.

[0050] The connector 100 is easy to use. Connecting stripped wires requires no tape, screwdrivers, or other tools, making it simple to operate and highly practical.

[0051] Furthermore, when the conductor is pulled, the compression component 20 is insufficient to resist the pull of the stripped wire, resulting in the stripped part of the wire being exposed on the outside of the housing 10, which reduces the safety of the wire and affects its practicality. In order to improve the tensile strength of the wire, a wire fixing component 50 is installed at the wire inlet 11 to fix the wire and improve the tensile strength of the wire.

[0052] Specifically, the fixed wiring assembly 50 can adopt... Figure 6 The structure shown includes a circular tube 51 and two semi-circular clips 52 used in combination. The wire is placed between the two semi-circular clips 52. When the two semi-circular clips 52 are joined together, they squeeze the wire, and the wire forms a strong friction with the inner surface of the two semi-circular clips 52. The joined two semi-circular clips 52 are inserted into the circular tube 51, and the two semi-circular clips 52 are fixed by the circular tube 51, thereby fixing the wire at the inlet 11 and improving the wire's tensile strength.

[0053] Preferably, an elastic pad 52b is provided on the inner surface of the two semi-circular buckles 52. The elastic pad 52b can be made of rubber or soft plastic elastic material. Providing the elastic pad 52b can increase the contact surface between the two semi-circular buckles 52 and the wire. The two semi-circular buckles 52 tightly cover the outside of the wire, and the friction between the two is stronger, which further improves the tensile strength of the wire.

[0054] Specifically, the round tube 51 secures the two semi-circular buckles 52 as follows: Figure 1 , 6 As shown, at least two arc-shaped stops 51a are evenly connected at intervals on the inner surface of the circular tube 51. Arc-shaped stops 52a are connected to one end of two combined semi-circular buckles 52 inserted into the circular tube 51. The number and position of the arc-shaped stops 51a and the arc-shaped stops 52a correspond. Each semi-circular buckle 52 is connected to at least one arc-shaped stop 52a. The connected arc-shaped stops 52a should preferably avoid the joint between the two semi-circular buckles 52. The arc width of the arc-shaped stop 52a is smaller than the arc width between the two arc-shaped stops 51a. After the wires are fixed inside the two semi-circular buckles 52, they are inserted into the round tube 51. The arc-shaped buckle 52a enters the round tube 51 along the gap between the two arc-shaped stops 51a. The two semi-circular buckles 52 are inserted into the round tube 51, and the position of the arc-shaped buckle 52a extends beyond the inner end face of the arc-shaped stop 51a. At this time, the two semi-circular buckles 52 are rotated so that the arc-shaped buckle 52a is blocked by the inner end face of the arc-shaped stop 51a, so that the two semi-circular buckles 52 are fixed inside the round tube 51.

[0055] It should be noted that the outer shape of the housing 10 of the present invention can take various forms, for example... Figure 1-8 The rectangular shell 10 shown can also be cylindrical or other shapes. In this case, only the shapes of the clamping assembly 20, the connecting plate 40 and the clamping frame 30 need to be adjusted accordingly. Under the guidance of this invention, those skilled in the art can achieve this without additional intellectual labor. The following focuses on the structure of the rectangular shell 10.

[0056] Example 1: As Figure 3 , 4As shown, the housing 10 is rectangular in shape, and its six sides are side 10a, side 210b, side 310c, side 410d, end 110e, and end 210f. Side 10a, side 210b, side 310c, and side 410d are the four sides of the housing 10, and end 110e and end 210f are the two end faces of the housing 10. Correspondingly, the clamping frame 30 matches the shape of the housing 10 and is cylindrical, that is, the clamping frame 30 is open at the end face 110e and end face 210f of the housing 10.

[0057] End face 10e has an inlet port 11, and end face 20f has a slot 13 for inserting the connecting plate 40; side face 10a has two through holes 14 for passing through the compression spring 22, and the outer wall of side face 10a also has a plate groove 15 for placing the outer clamping plate 21 of the housing 10; the inner wall of side face 30c has a plate groove 26 for placing the connecting plate 40 of another connecting component 100; the plate groove 216 and the connecting plate 40 together form a splicing plate cavity; side face 20b is an opening to facilitate observation of the internal connection of the housing 10; side face 40d is a solid surface.

[0058] The clamping assembly 20 includes two parallel outer clamping plates 21b and an inner clamping plate 21a. The two clamping plates 21 have similar shapes, and the outer clamping plate 21b has the same shape as the plate groove 15. Two compression springs 22 are connected between the two clamping plates 21. The two compression springs 22 pass through two through holes 14 opened on the side 10a, and the two clamping plates 21 are located on both sides of the side 10a. The inner clamping plate 21a is connected to the positioning post 23, and the outer clamping plate 21b is connected to the positioning post sleeve 24. The compression springs 22 are sleeved on the outside of the positioning post 23 and the positioning post sleeve 24.

[0059] The connecting plate 40 is Z-shaped. The end plate 40a of the Z-shaped connecting plate 40 is inserted into the housing 10 through the slot 13 and abuts against the side 10c. The length of the end plate 40a is close to the length of the side 10c. The length of the end plate 40a is greater than the length of the end plate 40b. The end plate 40a can be glued to the inner side of the side 10c. The middle plate 40c of the Z-shaped connecting plate 40 can also be glued to the outer side of the end face. The Z-shaped connecting plate 40 achieves a firm connection with the housing 10. The end plate 40a and the slot 16 form a splicing cavity. The splicing cavity is used to accommodate the end plate 40b of another connecting component. The bending structure of the Z-shaped connecting plate 40 can make the two connecting components 100 coplanar when they are combined, forming a regular appearance, reducing the space occupied by the two connecting components 100 after combination, and also ensuring that the two connecting components 100 are not easily scratched and maintain a stable connection.

[0060] The end face 10e inlet 11 is connected to the round tube 51. After the two semi-circular buckles 52 press the wire, they are inserted into the round tube 51. The two semi-circular buckles 52 and the round tube 51 are firmly connected by the arc-shaped stop block 51a blocking the arc-shaped buckle 52a, so that the wire maintains a strong tensile strength.

[0061] When in use, pulling the outer clamping plate 21b separates the inner clamping plate 21a from the end plate 40a. The stripped wire extends between the inner clamping plate 21a and the end plate 40a, squeezing the outer clamping plate 21b. The inner clamping plate 21a is then pressed by the elastic force of the compression spring 22, thereby achieving a tight connection between the stripped wire and the end plate 40a. The positioning post 23 is squeezed and slides within the positioning post sleeve 24, positioning the two clamping plates 21 to prevent them from shifting due to the compression of the compression spring 22. After the outer clamping plate 21b is pressed, it is placed in the plate groove 15. At this time, the clamping frame 30 is pushed to fix the clamping assembly 20.

[0062] Furthermore, such as Figure 3 , 8 As shown, the end of the clamping frame 30 near the housing 10 is provided with an inclined end face 30a, which makes it easy for the clamping frame 30 to slide and be fitted on the outside of the housing 10. Similarly, a chamfer 17 is provided on the end face 10e of the housing 10 near the clamping frame 30, which makes it easy for the clamping frame 30 to slide and be fitted on the outside of the housing 10.

[0063] Furthermore, such as Figure 4 As shown, end face 10f is offset towards the inside of housing 10 to form a misaligned groove 18. The space of the misaligned groove 18 formed by end face 10f is used to place the middle plate 40c, which can make the two connecting components 100 fit together more tightly.

[0064] Furthermore, such as Figure 6 As shown, the two combined semi-circular buckles 52 are provided with snap-fit ​​blocks 52c and snap-fit ​​grooves 52d for splicing. The two semi-circular buckles 52 are snapped together by snap-fit ​​blocks 52c and snap-fit ​​grooves 52d, making it difficult for them to slide against each other, which facilitates the insertion of the round tube 51. At the same time, it makes the two semi-circular buckles 52 fit together more tightly and has a better fastening effect on the wire.

[0065] Furthermore, such as Figure 6 As shown, the semi-circular buckle 52 and the arc-shaped buckle 52a are integrally manufactured to improve the overall strength of the semi-circular buckle 52.
