Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a high-strength terminal connector. Background Art

[0002] In the field of modern electrical connections, terminal connectors play a vital role. Terminal connectors are used to connect cables to electrical equipment or between different cables. The connection stability of the terminals is directly related to the reliability of the entire electrical system. When the existing equipment is in use, when the cable encounters a sudden external large pulling force, the cable end is easy to slide or separate from the terminal, affecting the continuity of the electrical connection and the stable operation of the system.

[0003] Referring to the Chinese patent document with announcement number CN119029623B and the name of a new type of terminal connector, it includes a plug-in mechanism, a drive group and a card-release unit are installed on the plug-in mechanism, the drive block on the drive group can drive the spring 1, the matching block, the rectangular plate, the spring rod 2 and the card-release plate on the card-release unit to clamp the terminal, and the drive group can drive the push circular plate on the card-release unit to press against the terminal in the front-to-back direction. When in use, by pushing the circular plate to press against the terminal in the front-to-back direction and correspondingly clamping the terminal in the left-to-right direction with the two card-release plates, the tight plug-in between the terminal and the connection seat can be ensured, and the problem of loose terminal and connection seat causing poor contact can be prevented.

[0004] Referring to the above technical solution, when the terminal is subjected to external tension, the movement of the driving block drives a series of components such as springs and plates to move, thereby tightening the connection between the terminal and other objects. The characteristic structure is often relatively complex. When the cable suddenly encounters external tension, the driving block on the driving component is required to urgently tighten the terminal at the cable connection. The operation is relatively complicated and easily brings additional burden to personnel. Summary of the invention

[0005] In view of this, the present application provides a high-strength terminal connector, which is mainly used to solve the problem of complex structural features of realizing the clamping function in traditional technologies.

[0006] In order to solve the above technical problems, the present application provides a high-strength terminal connector, including a base plate, a terminal and a cable, wherein a sliding plate one and a sliding plate two are installed on the base plate for horizontal sliding, the sliding plate one is set as an L-shaped plate, the sliding plate two is set at the inner corner of the L-shaped plate, the terminal is fixedly installed on the sliding plate two and is located directly above the sliding plate one, the terminal is connected to the cable, an extrusion block is penetrated through the side wall of the terminal housing, a fixed shaft for clamping the extrusion block is fixedly installed on the sliding plate one, a V-shaped pressure plate is installed on the base plate by rotating through the shaft, two V-shaped pressure plates are set, and a pushing shaft for applying pressure to the V-shaped pressure plate is installed on the sliding plate two.

[0007] By adopting the above technical solution, the sliding plate 1 slides laterally under the action of external force, which can drive the fixed shaft to move synchronously. The fixed shaft can squeeze the extrusion block to ensure that the connection between the sub-terminal and the female terminal inside the terminal is clamped and fixed. The sliding plate 2 slides laterally under the traction of the sudden external force of the cable, which can drive the pushing shaft to move. The pushing shaft can rotate the V-shaped pressure plate so that the V-shaped pressure plates on both sides clamp and fix the cable, thereby improving the fixing strength of the cable end and preventing the cable end from loosening or separating from the terminal.

[0008] Optionally, a guide shaft 1 is vertically installed on the sliding plate 1, and a guide shaft 2 is vertically installed on the sliding plate 2, and the cable passes through the terminal, the guide shaft 2 and the guide shaft 1 in sequence.

[0009] By adopting the above technical solution, the cable passes through the terminal, guide shaft 2 and guide shaft 1 in sequence. When the cable encounters external tension, guide shaft 2 approaches guide shaft 1 and releases part of the cable, which can buffer the sudden tension.

[0010] Optionally, a plurality of slots are provided on the sliding plate, and a spring piece which is locked in the slots is provided on the bottom plate.

[0011] By adopting the above technical solution, the spring sheet is set as a foldable spring sheet. When the sliding plate 1 slides horizontally, the spring sheet can be transformed into different card slots. When the traction force of the sliding plate 1 disappears, the sliding plate 1 can be ensured to slowly slide to the left and reset, which can reduce excessive vibration force on the cable and the terminal, and prevent looseness between the female terminal and the sub-terminal, and the cable and the terminal.

[0012] Optionally, a support block 1 is installed on the sliding plate 1, a support block 2 located on the right side of the support block 1 is installed on the bottom plate, a support shaft 1 penetrating the support block 2 is fixedly installed on the support block 1, and a return spring 1 is connected between the support blocks 1 and 2.

[0013] By adopting the above technical solution, when the external traction force cancels the traction on the sliding plate 1, the elastic force of the reset spring 1 is released, so that the sliding plate 1 can be reset.

[0014] Optionally, a support block three is installed on the bottom plate, a support block four located on the right side of the support block three is installed on the sliding plate two, a support shaft two penetrating the support block four is fixedly installed on the support block three, and a reset spring two is connected between the support block three and the support block four.

[0015] By adopting the above technical solution, when the cable loses traction on the sliding plate 2, the elastic force of the reset spring 2 is released, so that the sliding plate 2 can be reset.

[0016] Optionally, a limit plate is installed on the bottom plate, and the limit plate is used to limit the rotation angle of the V-shaped pressure plate.

[0017] By adopting the above technical solution, the limiting plate can limit the rotation angle of the V-shaped pressure plate to prevent the two V-shaped pressure plates from excessively squeezing the cables.

[0018] Optionally, a protective shell for covering the terminals is installed on the bottom plate.

[0019] By adopting the above technical solution, the protective shell covers the top of the terminal, which can prevent the terminal from being hit by external components and protect the stability of the terminal connection.

[0020] Optionally, a protective cover is installed on the bottom plate, and a connecting card plate is provided on the protective cover.

[0021] By adopting the above technical solution, the protective cover can protect the cable from dust, and the connecting card can connect two or more groups of terminals together.

[0022] In summary, compared with the prior art, the present application has at least one of the following beneficial technical effects: 1. When the cable is suddenly subjected to external tension, the two linked V-shaped pressure plates can clamp and fix the cable to prevent the loosening of the connection between the cable and the terminal. At the same time, the rotation angle of the V-shaped pressure plate is limited to prevent the V-shaped pressure plates on both sides from clamping the cable excessively and preventing the cable from being damaged. The structural design is simple and effective, and can prevent the loosening of the connection between the cable and the terminal in time.

[0023] 2. By displacing the two fixed axes, the clamping and fixing of the connection between the female terminal and the sub-terminal on the terminal can be easily completed to prevent the loosening of the connection on the terminal.

[0024] 3. The cable bending and winding design cleverly utilizes the physical properties of the cable itself. Through the pre-set bending path, the impact of external sudden traction on the connector is effectively buffered, reducing the risk of cable ends sliding due to direct force.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 6 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 The present embodiment provides a high-strength terminal connector, including a bottom plate 1, a terminal 2, a cable 3, a clamping and fixing component 4, a tension buffer component 5, and a reset component 6. The clamping and fixing component 4 includes a sliding plate 1 41 and a sliding plate 2 44, the terminal 2 is placed on the sliding plate 2 44, the cable 3 is connected to the terminal 2, the clamping and fixing component 4 can clamp and limit the connection between the female terminal and the sub-terminal on the terminal 2, and can also clamp and limit the connection between the terminal 2 and the cable 3. When the cable 3 is suddenly subjected to external tension, the tension buffer component 5 can buffer the influence of the external sudden traction force on the connection between the terminal 2 and the cable 3 through a specific bending path, and the reset component 6 can drive the sliding plate 1 41 and the sliding plate 2 44 to reset after sliding.

[0029] Reference Figure 3 and Figure 4 A protective shell 21 and a protective cover 11 are installed on the bottom plate 1, and a connecting card board 12 is installed on the protective cover 11. The protective shell 21 covers the terminal 2 to protect the terminal 2 and prevent the parts from colliding with the terminal 2. The protective cover 11 covers the entire terminal connector, and the connecting card board 12 is set as a hook-type card board to facilitate the connection of the entire terminal connector with other connectors.

[0030] Reference Figure 3 and Figure 4The clamping and fixing assembly 4 includes a sliding plate 2 44, a rotating shaft, a V-shaped pressure plate 45, a pushing shaft 46 and a limiting plate 47. The sliding plate 2 44 is installed on the bottom plate 1 for transverse sliding and is arranged in a rectangular shape. The sliding plate 2 44 is installed with a terminal 2. The cable 3 connected to the terminal 2 can drive the sliding plate to slide to the left when encountering an external tension. The bottom plate 1 is vertically installed with a rotating shaft located at the connection between the cable 3 and the terminal 2. There are two rotating shafts and they are arranged symmetrically front and back. A V-shaped pressure plate 45 is sleeved and installed on the rotating shaft. The V-shaped pressure plate 45 can clamp the cable 3 during the rotation process. The pushing shaft 46 is arranged as two fixedly installed on the sliding plate 2 44, which is used to rotate one side plate of the V-shaped pressure plate 45. The limiting plate 47 is vertically installed on the bottom plate 1, which can limit the rotation angle of the V-shaped pressure plate 45 to prevent the two V-shaped pressure plates 45 from excessively squeezing the cable 3.

[0031] During use, when the cable 3 encounters an external pulling force, the sliding plate 2 44 can slide to the left, and the pushing shaft 46 contacts one side plate of the V-shaped pressure plate 45 and pushes the V-shaped pressure plate 45 to rotate around the rotating shaft, so that the V-shaped pressure plates 45 on both sides squeeze the cable 3 to prevent the connection between the cable 3 and the terminal 2 from loosening when the cable 3 encounters an external pulling force, thereby ensuring the stability of the connection. When one edge of the V-shaped pressure plate 45 contacts the limit plate 47, the V-shaped pressure plate 45 can stop rotating. At this time, the sliding plate 2 44 stops sliding, which can prevent the V-shaped pressure plate 45 from excessively squeezing the cable 3 and preventing the cable 3 from being damaged.

[0032] Reference Figure 3 , Figure 4 and Figure 5 The clamping and fixing assembly 4 also includes a sliding plate 41, an extrusion block 42, a fixed shaft 43, a slot 411 and a spring 412. The sliding plate 41 is installed on the bottom plate 1 for transverse sliding and is set as an L-shaped plate. The L-shaped plate includes a short side plate and a long side plate. The sliding plate 44 is set at the inner corner of the L-shaped plate. The sliding plate 41 is pushed by an external driving force. The terminal 2 is placed transversely on the sliding plate 44 and is located above the short side plate of the L-shaped plate.

[0033] The front and rear sides of the terminal 2 are symmetrically provided with through holes, and an extrusion block 42 is installed on the through holes through a torsion spring. The extrusion block 42 is set to be in a rectangular shape, one side of which is set to an inclined surface, and the fixed shaft 43 is set to be two, both of which are fixedly installed on the short side plate of the sliding plate 41 and are respectively located on the front and rear sides of the terminal 2. When the fixed shaft 43 slides following the sliding plate 41, the fixed shaft 43 contacts the inclined surface of the extrusion block 42 and drives the extrusion block 42 to press toward the inside of the terminal 2. The card slot 411 is set to be opened on the sliding plate 41 in multiple arrays, and there is a certain gap between the bottom of the sliding plate 41 and the top of the bottom plate 1. The spring sheet 412 is installed on the bottom plate 1 and is set to two, and a single spring sheet 412 corresponds to a single card slot 411 respectively. The spring sheet 412 is set to be a foldable spring sheet 412. When the sliding plate 41 slides horizontally, the spring sheet 412 can be transformed into different card slots 411. The spring sheet 412 is set to be two to enhance the stability of the sliding plate 41 when it slides.

[0034] When in use, the sliding plate 41 slides to the right under the external push, and the fixed shaft 43 slides synchronously with the sliding plate 41. The fixed shaft 43 moves one end of the extrusion block 42 toward the inside of the terminal 2 along the inclined surface of the extrusion block 42, so that the extrusion block 42 clamps and limits the connection between the female terminal and the sub-terminal inside the terminal 2 to prevent the female terminal and the sub-terminal from loosening. Synchronously, the spring piece 412 installed on the bottom plate 1 of the sliding plate 41 can change its position in different slots 411. When the external driving force of the sliding plate 41 disappears, under the limit of the spring piece 412 and the slot 411, the sliding plate 41 slowly slides to the left and resets, thereby reducing the excessive vibration force on the connection between the cable 3 and the terminal 2.

[0035] Reference Figure 3 The tension buffer assembly 5 includes a guide shaft 1 51 and a guide shaft 2 52. The guide shaft 1 51 is vertically fixedly installed at the right end of the long side plate of the sliding plate 1 41, and the guide shaft 2 52 is vertically fixedly installed at the right end of the sliding plate 2 44, and the guide shaft 2 52 is located on the right side of the guide shaft 1 51. The guide shaft 1 51 and the guide shaft 2 52 are both sleeved with a rotating shell. The cable 3 passes through the terminal 2, the guide shaft 2 52 and the guide shaft 1 51 in sequence. When the cable 3 suddenly encounters external tension, the guide shaft 2 52 and the cable 3 on the guide shaft 1 51 can buffer the tension. When the cable 3 rotates, the rotating shell can reduce the friction between the rotating shell and the cable 3 to prevent the cable 3 from being damaged too quickly.

[0036] When in use, the cable 3 is passed around the guide shaft 2 52 and the guide shaft 1 51 in turn, and one end of the cable 3 is connected to the terminal 2. When the cable 3 encounters external tension, the cable 3 rotates on the rotating shell on the guide shaft 2 52 and the guide shaft 1 51, and the rotating shell rotates synchronously to reduce the friction between the cable 3 and the rotating shell. The cable 3 passed around the guide shaft 2 52 and the guide shaft 1 51 buffers the tension to prevent the connection between the cable 3 and the terminal 2 from being directly affected by the tension.

[0037] Reference Figure 5 The reset assembly 6 includes a support block 1 61, a support block 2 62, a support shaft 1 63 and a reset spring 1 64. The support block 1 61 is installed at the bottom of the sliding plate 1 41, the support block 2 62 is installed at the top of the bottom plate 1, the support block 2 62 is located on the right side of the support block 1 61, the support shaft 1 63 is fixedly installed on the support block 1 61, the support block 2 62 is provided with a through hole, the support shaft 1 63 penetrates the through hole of the support block 2 62, a reset spring 1 64 is connected between the support block 1 61 and the support block 2 62, and the reset spring 1 64 surrounds the support shaft 1 63. After the sliding plate 1 41 slides to the right, when the external thrust disappears, the sliding plate 1 41 can be reset under the drive of the support block 1 61, the support block 2 62, the support shaft 1 63 and the reset spring 1 64.

[0038] Reference Figure 6 , the reset assembly 6 also includes a support block 3 65, a support block 4 66, a support shaft 2 67 and a reset spring 2 68. The support block 4 66 is installed at the bottom of the sliding plate 2 44, the support block 3 65 is installed at the top of the bottom plate 1, the support block 4 66 is located on the right side of the support block 3 65, the support shaft 2 67 is fixedly installed on the support block 3 65, the support block 4 66 is also provided with a through hole, the support shaft 2 67 runs through the through hole of the support block 4 66, the reset spring 2 68 is connected between the support block 3 65 and the support block 4 66, and the reset spring 2 68 surrounds the support shaft 2 67. After the sliding plate 2 44 slides to the left, when the pulling force of the cable 3 disappears, the sliding plate 2 44 can be reset under the drive of the support block 1 61, the support block 2 62, the support shaft 1 63 and the reset spring 1 64.

[0039] When in use, the sliding plate 41 slides to the right when it is pushed by an external force, the support block 61 approaches the support block 2 62, and the return spring 64 is compressed. When the external force disappears, the elastic force of the return spring 64 is released, pushing the support block 61 to slide to the left, so that the sliding plate 41 is reset. Similarly, when the sliding plate 41 slides to the left due to the pulling force of the cable 3, the support block 4 66 approaches the support block 3 65, and the return spring 2 68 is compressed. When the pulling force of the cable 3 disappears, the elastic force of the return spring 2 68 is released, pushing the support block 4 66 to slide to the right, so that the sliding plate 2 44 is reset.

[0040] The implementation principle of a high-strength terminal connector in the embodiment of the present application is: When using the device, firstly connect the female terminal and the sub-terminal on the terminal 2, and connect one end of the terminal 2 to the cable 3, so that the cable 3 passes through the second guide shaft 52 and the first guide shaft 51 in sequence.

[0041] Then, an external thrust is used to slide the sliding plate 41 to the right, and the fixed shaft 43 on the sliding plate 41 slides to the right synchronously. The fixed shafts 43 on both sides squeeze the extrusion block 42, so that the extrusion block 42 clamps and fixes the connection between the female terminal and the sub-terminal inside the terminal 2. When the cable 3 suddenly encounters external tension, the cable 3 on the guide shaft 51 and the guide shaft 2 52 buffers the tension. Then, the tension exerted on the cable 3 drives the sliding plate 2 44 to slide to the left, so that the pushing shaft 46 contacts one side plate of the V-shaped pressure plate 45, and the V-shaped pressure plate 45 rotates on the rotating shaft. The V-shaped pressure plates 45 on both sides clamp and limit the cable 3 to prevent the wire tension from generating excessive pulling force on the connection between the cable 3 and the terminal 2, and prevent the connection between the cable 3 and the terminal 2 from loosening.

[0042] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
