Description

Technical Field

[0001] This utility model relates to the field of wire harness terminal technology, and in particular to a convenient terminal structure with quick plug-in / plug-out function. Background Technology

[0002] Wire harness terminals are conductive components that can form circuits with corresponding conductive components. Terminals include both pins and sockets, which serve as electrical connections and are used for power supply and signal transmission of equipment. The materials used are copper and its alloys, which are good conductors. Their surfaces are plated with silver, gold, or tin to improve corrosion resistance, oxidation resistance, and rust prevention. Wire harness terminals are widely used in the electronics field.

[0003] As shown in the reference case "A Quick-Plug-in Terminal Block" (publication number CN219534923U), when the corresponding limit plate one and limit plate two are pulled outward by the pull ring, the terminal block is engaged with the terminal block. This design allows for quick plugging and unplugging, is simple to follow, and meets the user's needs.

[0004] However, existing structures generally use elastic blocks or snap-fit ​​limiting plates for fixation. During repeated insertion and removal, the limiting plate and the terminal plug rub against each other repeatedly. Long-term use will cause slight deformation of the metal surface, resulting in a decrease in locking force.

[0005] Therefore, a convenient terminal structure with quick plug-in / plug-out function is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a convenient terminal structure with quick insertion and removal function to solve the above problems. It improves the problem that the existing structure generally uses elastic blocks or snap-fit ​​limiting plates for fixation. During multiple insertion and removal processes, the limiting plate and the terminal plug rub against each other repeatedly. Long-term use will cause slight deformation of the metal surface, resulting in a decrease in locking force.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a convenient terminal structure with quick insertion and removal function, comprising: a first connecting terminal and a second connecting terminal; and an insertion and removal mechanism for quickly inserting and removing the first connecting terminal and the second connecting terminal. The insertion and removal mechanism includes two connecting slots on one side of the second connecting terminal, and a quick-connect component is provided between the two connecting slots and the first connecting terminal. A limiting component is provided on the outer side of the first connecting terminal. During use, the first connecting terminal and the second connecting terminal can be quickly connected via the quick-connect component. Since the quick-connect component is fixed by sliding connection and locking, it eliminates the need for traditional snap-fit ​​elastic deformation and forceful insertion and removal, making the insertion and removal process smoother. The sliding connection and locking structure reduces direct friction between metal terminals, reduces material fatigue, and improves terminal durability. After the quick-connect component is connected, the terminal structure can be limited by the limiting component, which is very convenient.

[0008] Preferably, a fixing block is fixedly installed on one side of each of the two connecting slots, and a slider is slidably installed on one side of each of the two fixing blocks. An insert block is fixedly connected to the adjacent side of each of the two sliders. Two connecting plates are fixedly installed on one side of the first connecting terminal. The two connecting plates are respectively located between the two sliders, and two insertion holes are opened on the opposite side of each of the two connecting plates. The two insertion blocks of the slider are locked and connected to the two insertion holes of the adjacent connecting plates. When the second connecting terminal is close to the first connecting terminal, the slider can be moved to one side of the two connecting plates by the two fixing blocks. At this time, the two sliders are respectively located on one side of the two connecting plates. The insertion block on one side of the slider is slidably connected to the insertion hole. Since the connection process is a sliding connection and limit locking, the elastic deformation and jamming friction of the traditional snap-fit ​​plug-in terminal are avoided, effectively reducing the wear of the metal terminal surface.

[0009] Preferably, the surface of the connecting plate has two guide grooves, one end of each guide groove extends out of the connecting plate, and the other end of each guide groove is connected to two insertion holes respectively. After the slider moves the insertion block close to the connecting plate, the two insertion blocks move into the interior of the two guide grooves respectively. Through the guide grooves, the insertion blocks can move along a fixed path during the insertion process, ensuring that there is no offset or skew during the insertion process, and avoiding unstable terminal connection.

[0010] Preferably, two guide blocks are fixedly installed on both sides of the first connecting terminal. The guide blocks on the same side are respectively located on both sides of the connecting plate. The adjacent side of the guide blocks is set as an inclined surface. Both sides of the fixing block are set as inclined surfaces. The fixing block slides in contact with the two adjacent guide blocks. When the two guide blocks on both sides are inserted, the guide blocks can form a sliding contact with the fixing blocks, gradually correcting the insertion direction, improving the accuracy and consistency of the connection, and reducing the risk of insertion failure.

[0011] Preferably, a gasket is fixedly installed on one side of the guide block, and the other side of the gasket abuts against the inner wall of the connecting groove. When the first connecting terminal and the second connecting terminal are connected to each other, the guide block presses the gasket against the inside of the connecting groove. The gasket acts as a buffer layer, providing a buffering effect between the guide block and the inner wall of the connecting groove, reducing frictional loss caused by direct metal contact during insertion and removal, and improving the service life of the terminal.

[0012] Preferably, the limiting component includes a movable frame fixedly installed on the surface of the slider, the surface of the movable frame is provided with a positioning groove, a positioning block is provided on one side of the connecting plate, the positioning block is rotatably installed on the surface of the first connecting terminal, and one side of the positioning block is slidably connected to the positioning groove. After the slider is slidably connected to the connecting plate, the slider can be limited by rotating the positioning block to connect with the positioning groove, so as to prevent the terminal from loosening or displacing under the action of external force.

[0013] Preferably, a movable block is slidably installed inside the socket, and a spring is fixedly installed between the movable block and the socket. The movable block is located on one side of the socket and abuts against the socket. When the positioning block rotates and separates from the positioning groove, the spring pushes the movable block to move upward and push the socket out of the socket. At this time, the slider also separates from the corresponding connecting plate simultaneously, thereby achieving rapid separation.

[0014] The beneficial effects of this utility model are:

[0015] 1. During use, the first and second connecting terminals can be quickly connected using the quick-connect assembly. Since the quick-connect assembly is fixed by sliding connection and locking, there is no need for traditional snap-fit ​​elastic deformation, forceful insertion and removal, etc., making the insertion and removal process smoother. The sliding connection and locking structure can reduce direct friction between metal terminals, reduce material fatigue, and improve terminal durability. After the quick-connect assembly is connected, the terminal structure can be limited by the limiting component, which is very convenient.

[0016] 2. After the slider and the connecting plate are slidably connected, the slider can be limited by the rotation of the positioning block and the connection with the positioning groove to prevent the terminal from loosening or displacement under the action of external force. When the positioning block rotates and separates from the positioning groove, the spring pushes the moving block to move upward and push the insertion block out of the insertion hole. At this time, the slider is also separated from the corresponding connecting plate at the same time, so as to achieve rapid separation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a convenient terminal structure with quick plug-in / plug-out function includes: a first connecting terminal 1 and a second connecting terminal 2; a plug-in / plug-out mechanism 3 for quickly plugging and unplugging the first connecting terminal 1 and the second connecting terminal 2; wherein, the plug-in / plug-out mechanism 3 includes two connecting slots 31 opened on one side of the second connecting terminal 2, a quick-connect component 32 is provided between the two connecting slots 31 and the first connecting terminal 1, and a limiting component 33 is provided on the outer side of the first connecting terminal 1. In use, the first connecting terminal 1 and the second connecting terminal 2 can be quickly connected through the quick-connect component 32. Since the quick-connect component 32 is fixed by sliding connection and locking, there is no need for traditional snap-fit ​​elastic deformation, forceful plugging and unplugging, etc., making the plugging and unplugging process smoother. The sliding connection and locking structure can reduce direct friction between metal terminals, reduce material fatigue, and improve terminal durability. After the quick-connect component 32 is connected, the terminal structure can be limited by the limiting component 33, which is very convenient.

[0024] When the insertion / removal mechanism 3 is in use, it only guides the first connecting terminal 1 and the second connecting terminal 2 to move closer together. The connection process of the first connecting terminal 1 and the second connecting terminal 2 is improved and optimized without affecting their normal use or the original usage process of the first connecting terminal 1 and the second connecting terminal 2.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, a fixing block 321 is fixedly installed on one side of each of the two connecting slots 31, and a slider 322 is slidably installed on one side of each of the two fixing blocks 321. An insert block 323 is fixedly connected to the adjacent side of each slider 322. Two connecting plates 324 are fixedly installed on one side of the first connecting terminal 1, respectively located between the two sliders 322. Two insertion holes 326 are provided on the opposite sides of each connecting plate 324. The two insertion blocks 323 of the slider 322 are locked into the two insertion holes 326 of the adjacent connecting plate 324. When the first connecting terminal 1 and the second connecting terminal 2 are quickly connected, when the second connecting terminal 2 is close to the first connecting terminal 1, the two fixing blocks 321 can drive the slider 322 to move to one side of the two connecting plates 324. This allows the two sliders 322 to... Located on one side of the two connecting plates 324, the insert 323 on one side of the slider 322 is slidably connected to the socket 326. Since the connection process is a sliding connection and limit locking, the elastic deformation and jamming friction of the traditional snap-fit ​​plug-in terminal are avoided, effectively reducing the wear of the metal terminal surface. The surface of the connecting plate 324 has two guide grooves 325. One end of each guide groove 325 extends out of the connecting plate 324, and the other end of each guide groove 325 is connected to the two sockets 326 respectively. After the slider 322 drives the insert 323 to approach the connecting plate 324, the two inserts 323 move into the interior of the two guide grooves 325 respectively. Through the guide grooves 325, the insert 323 can move along a fixed path during the insertion process, ensuring that there is no offset or skew during the insertion process, and avoiding unstable terminal connection.

[0026] Two guide blocks 327 are fixedly installed on both sides of the first connecting terminal 1. The guide blocks 327 on the same side are located on both sides of the connecting plate 324. The adjacent sides of the guide blocks 327 are all set as bevels. Both sides of the fixing block 321 are also set as bevels. The fixing block 321 slides in contact with the two adjacent guide blocks 327. When the two guide blocks 327 on both sides are inserted, the guide blocks 327 can form a sliding contact with the fixing block 321, gradually correcting the insertion direction, improving the accuracy and consistency of the connection, and reducing the risk of insertion failure. A gasket 328 is fixedly installed on one side of the guide block 327. The other side of the gasket 328 abuts against the inner wall of the connecting groove 31. When the first connecting terminal 1 and the second connecting terminal 2 are connected to each other, the guide block 327 presses the gasket 328 against the inside of the connecting groove 31. The gasket 328 acts as a buffer layer, providing a buffering effect between the guide block 327 and the inner wall of the connecting groove 31, reducing frictional loss caused by direct metal contact during insertion and removal, and improving the service life of the terminal.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the limiting component 33 includes a movable frame 331 fixedly mounted on the surface of the slider 322. A positioning groove 332 is formed on the surface of the movable frame 331. A positioning block 333 is provided on one side of the connecting plate 324. The positioning block 333 is rotatably mounted on the surface of the first connecting terminal 1. One side of the positioning block 333 is slidably connected to the positioning groove 332. After the slider 322 is slidably connected to the connecting plate 324, the positioning block 333 rotates and connects to the positioning groove 332, thus limiting the slider 322 and preventing it from shifting. When the insert is loosened or displaced under external force, a moving block 334 is slidably installed inside the insertion hole 326. A spring 335 is fixedly installed between the moving block 334 and the insertion hole 326. The moving block 334 is located on one side of the insertion block 323 and abuts against the insertion block 323. When the positioning block 333 rotates and separates from the positioning groove 332, the spring 335 pushes the moving block 334 upward to push the insertion block 323 out of the insertion hole 326. At this time, the slider 322 also separates from the corresponding connecting plate 324 simultaneously, thereby achieving rapid separation.

[0028] In use, when the second connecting terminal 2 approaches the first connecting terminal 1, the two fixing blocks 321 can drive the slider 322 to move to one side of the two connecting plates 324. At this point, the two sliders 322 are respectively located on one side of the two connecting plates 324. The insertion block 323 on one side of the slider 322 then slides into the insertion hole 326. Because the connection process involves sliding connection and limit locking, it avoids the elastic deformation and jamming friction of traditional snap-fit ​​terminals, effectively reducing wear on the metal terminal surface. After the slider 322 drives the insertion block 323 closer to the connecting plate 324, the two insertion blocks 323 then... Do not move into the interior of the two guide grooves 325. The guide grooves 325 allow the insert block 323 to move along a fixed path during the insertion process. After the slider 322 is slidably connected to the connecting plate 324, the positioning block 333 rotates and connects with the positioning groove 332 to limit the slider 322 and prevent the terminal from loosening or displacing under external force. When the positioning block 333 rotates and separates from the positioning groove 332, the spring 335 pushes the moving block 334 upward to push the insert block 323 out of the insertion hole 326. At this time, the slider 322 also separates from the corresponding connecting plate 324 simultaneously, thus achieving rapid separation.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
