Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-stability connector terminal connection structure. Background Technology

[0002] Connectors, often called circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. As a type of motor system, electronic connectors provide a separable interface to connect two secondary electronic systems. Simply put, they are components that complete the electrical connection between circuits or electronic machines, acting as a bridge between them.

[0003] Patent CN113922156B discloses a quick-connect terminal connection structure and connector. The structure includes a base frame, a substrate disposed on the bottom surface of the base frame with one end extending out of the base frame, and a top cover mounted on and hinged to the base frame. An upwardly curved elastic sheet is fixedly connected to the top surface of the substrate near the hinge point. The top cover has a pushing block for pressing the elastic sheet with a push wire. An elastic guide frame for guiding the wire through is fixedly connected to the side of the substrate away from the hinge point. The top cover also has a clamping assembly for pushing the guide frame to elastically deform and clamp the wire. An opening for the wire to pass through is provided on the base frame. Several latches are fixedly connected to the side of the top cover away from the hinge point. Slots that engage with these latches are provided on the base frame. This invention increases the contact area between the pushing block and the wire by providing an elastic layer at the bottom of the pushing block, reducing the possibility of the wire slipping out of the base frame, thereby improving the stability of the connection between the wire and the base frame.

[0004] However, the terminal connection structure of the above connector still has defects. This structure uses the compression of the elastic sheet and elastic guide frame when the top cover is connected to the bottom frame to clamp and limit the wires, so as to improve the connection stability and prevent them from falling off. However, this method will cause the substrate to be subjected to compressive stress for a long time. After long-term use, it is easy to cause the substrate to deform, crack or material to age. Moreover, the effect of fixing and preventing the wires from falling off is not satisfactory. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a highly stable connector terminal connection structure to solve the technical problem that the current connector terminal connection structure causes damage to the substrate due to the squeezing force, and has poor guiding, fixing and anti-loosening effect.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A high-stability connector terminal connection structure includes a base frame, a top cover on the top of the base frame, a wire inlet hole at one end of the base frame, a base plate with one end penetrating one side of the base frame at the bottom of the base frame, a connecting mechanism on the top of the base plate, and a fixing component connecting the top cover and the base frame. The connecting mechanism includes a guide plate disposed on the top of the top cover near the wire inlet hole. Rectangularly distributed adjustment grooves are provided on corresponding portions of the base plate and the bottom of the base frame. A movable block connected to the guide plate is slidably installed in the adjustment groove. A guide post is symmetrically provided at the end of the movable block away from the guide plate. The inner wall of the adjustment groove at the bottom of the base frame is symmetrically provided with rail grooves adapted to the guide post.

[0009] As an improved technical solution, the connecting mechanism further includes a first spring plate, which is fixedly installed in an adjustment groove opened at the bottom of the bottom frame, and the first spring plate is located on the opposite outer side of the moving block. A pressure block is fixedly installed at the bottom of the top cover corresponding to the guide plate.

[0010] As an improved technical solution, the connecting mechanism further includes a second spring sheet, which is disposed on the top of the substrate away from the guide sheet. Lower extrusion blocks are symmetrically arranged on both sides of the second spring sheet. A first sliding groove adapted to the lower extrusion block is symmetrically opened on the top of the substrate. A second sliding groove is opened at the bottom of the bottom frame corresponding to the position of the first sliding groove. A slider is slidably installed in the second sliding groove and is fixedly connected to the lower extrusion block. A push block is provided above the second spring sheet and fixedly connected to the bottom of the top cover. Rubber blocks are symmetrically arranged on the bottom of the top cover outside the push block. Upper extrusion blocks adapted to the lower extrusion block are symmetrically arranged on both sides of the push block.

[0011] As an improved technical solution, the guide plate is elastic, and both the guide plate and the second spring plate are bent into an inverted U-shape. The bottom surface of the push block is a curved surface that is concave towards the top cover, and the inner wall of the push block is provided with a rubber pad.

[0012] As an improved technical solution, the bottom of each rubber block is provided with an inclined rubber strip, and the rubber strips installed at the bottom of the two rubber blocks are inclined in opposite directions. The lower extrusion block and the upper extrusion block are both right-angled trapezoids, and the slider is a convex structure.

[0013] As an improved technical solution, a guide groove is provided on the top of the second spring sheet, and a rubber layer is provided inside the guide groove.

[0014] As an improved technical solution, the fixing component includes a connecting frame, which is symmetrically arranged on the top of the bottom frame. Both ends of the top cover are symmetrically provided with slots that are adapted to the connecting frame. A storage groove is provided on one side wall of the slot. An inclined metal spring is fixedly installed in the storage groove. A locking block is fixedly connected to one end of the metal spring, and the end of the locking block away from the metal spring passes through the connecting frame.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model, through a connecting mechanism, allows the wire to pass through the inlet hole, be guided by the guide plate, and then laid on the second spring plate. The top cover is then installed on the bottom frame. Under the squeezing action of the pressure block, push block, and upper extrusion block, and through transmission, the guide plate moves downward to squeeze the wire, and the second spring plate squeezes the wire upward, thereby tightly clamping and fixing the wire, improving the connection and fixing effect and the wire's anti-detachment effect, making the connection more stable. Furthermore, the stress generated by the deformation of the second spring plate and guide plate is applied to the bottom frame, preventing the substrate from being subjected to long-term pressure and thus avoiding damage. This makes it more practical.

[0017] 2. The fixing component of this utility model can easily connect and fix or separate the top cover and the bottom frame, and the connection between the two is more secure. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0034] like Figure 1 - Figure 4 and Figure 5 - Figure 7 As shown in the figure, this embodiment provides a high-stability connector terminal connection structure, including a bottom frame 1, a top cover 2 on the top of the bottom frame 1, a wire inlet hole at one end of the bottom frame 1, a base plate 5 with one end penetrating one side of the bottom frame 1 at the bottom of the bottom, a connection mechanism 3 on the top of the base plate 5, and a fixing component 4 connecting the top cover 2 and the bottom frame 1; the connection mechanism 3 includes a guide plate 301, which is disposed on the top of the top cover 2 near the wire inlet hole, and rectangular adjustment grooves 302 are provided in corresponding portions of the bottom of the base plate 5 and the bottom of the bottom. A moving block 303 connected to the guide plate 301 is slidably installed in the adjustment groove 302, and a guide post 304 is symmetrically provided at the end of the moving block 303 away from the guide plate 301. The inner wall of the adjustment groove 302 at the bottom of the bottom of the bottom frame 1 is symmetrically provided with rail grooves 305 adapted to the guide post 304.

[0035] In this example, the connecting mechanism 3 also includes a first spring plate 306, which is fixedly installed in the adjustment groove 302 opened at the bottom of the bottom frame 1. The first spring plate 306 is located on the opposite side of the moving block 303. A pressure block 307 is fixedly installed at the bottom of the top cover 2 corresponding to the guide plate 301. When the top cover 2 is connected to the bottom frame 1, the pressure block 307 can press down on the guide plate 301, causing the guide plate 301 to deform under force. This causes the lower end of the guide plate 301 to drive the moving block 303 and the guide post 304 to move towards the side of the first spring plate 306, so that the moving block 303 squeezes the first spring plate 306 to deform until the lower end of the moving block 303 passes over the first spring plate 306. After that, the moving block 303 will continue to move away from the guide plate 301 in the adjustment groove 302. At the same time, the middle position of the guide plate 301 will gradually move downward, thereby pressing and limiting the guide.

[0036] In this example, the connecting mechanism 3 also includes a second spring sheet 308. The second spring sheet 308 is disposed on the top of the substrate 5 away from the guide sheet 301. Lower extrusion blocks 309 are symmetrically arranged on both sides of the second spring sheet 308. A first sliding groove 311 adapted to the lower extrusion block 309 is symmetrically opened on the top of the substrate 5. A second sliding groove 312 is opened at the bottom of the bottom frame 1 corresponding to the position of the first sliding groove 311. A slider 310 is slidably installed in the second sliding groove 312, and the slider 310 is fixedly connected to the lower extrusion block 309. A push block 313 fixedly connected to the bottom of the top cover 2 is provided above the second spring sheet 308. Rubber blocks 315 are symmetrically arranged on the outside of the push block 313 at the bottom of the top cover 2. Upper extrusion blocks 314 adapted to the lower extrusion block 309 are symmetrically arranged on both sides of the push block 313, so that the push block 313 presses down on the lower wire and presses down on the second spring sheet 308, causing the second spring sheet 308 to... When the spring 308 deforms, the push block 313 also moves the upper extrusion block 314 downward, so that the inclined surface at the lower end of the upper extrusion block 314 fits against the inclined surface at the upper end of the lower extrusion block 309. This squeezes the lower extrusion block 309, causing the slider 310 to slide along the second groove 312. This causes the lower extrusion blocks 309 on both sides of the second spring sheet 308 to move inward, thereby squeezing and deforming the second spring sheet 308. This causes the middle part of the second spring sheet 308 to bend and concave towards the push block 313, thus pushing the wire to fit tightly against the push block 313. This further improves the restriction and fixation effect on the wire, making the connection more stable and improving the wire's anti-detachment effect. At the same time, the force generated by the guide plate 301 and the second spring sheet 308 acts on the base frame 1, preventing the force generated from acting on the substrate 5 for a long time, which could lead to damage.

[0037] In this example, the guide plate 301 is elastic, and both the guide plate 301 and the second spring plate 308 are bent into an inverted U-shape. The bottom surface of the push block 313 is a curved surface that is concave towards the top cover 2. The inner wall of the push block 313 is provided with a rubber pad so as to increase the friction between the push block 313 and the wire, thereby improving the limiting and fixing effect on the wire.

[0038] In this example, the bottom of each rubber block 315 is provided with an inclined rubber strip, and the rubber strips installed at the bottom of the two rubber blocks 315 are inclined in opposite directions. The lower extrusion block 309 and the upper extrusion block 314 are both right-angled trapezoids, and the slider 310 has a convex structure so that the rubber strip can guide the wire in one direction, thereby improving the stability of the wire adjustment.

[0039] In this example, the top of the second spring sheet 308 is provided with a guide groove, and a rubber layer is provided in the guide groove to increase the friction between it and the wire.

[0040] like Figure 1 - Figure 2 and Figure 4 - Figure 5As shown, in this example, the fixing component 4 includes a connecting frame 404, which is symmetrically arranged on the top of the bottom frame 1. Both ends of the top cover 2 are symmetrically provided with slots that fit the connecting frame 404. A storage slot 402 is provided on one side wall of the slot. An inclined metal spring 401 is fixedly installed in the storage slot 402. A locking block 403 is fixedly connected to one end of the metal spring 401. The end of the locking block 403 away from the metal spring 401 passes through the connecting frame 404 to facilitate quick connection or disassembly between the bottom frame 1 and the top cover 2.

[0041] In use, the wire is inserted into the bottom frame 1 through the inlet hole and guide plate 301, and laid on the second spring plate 308. Then, the top cover 2 is connected to the bottom frame 1. By pressing the locking block 403 into the storage slot 402 and squeezing the metal spring plate 401, the top cover 2 can be installed on the top of the bottom frame 1. When the locking block 403 is aligned with the connecting frame 404, the locking block 403 will reset under the elastic force of the metal spring plate 401, thereby allowing the locking block 403 to pass through the locking block 408. 03, which fixes the connection between the top cover 2 and the bottom frame 1; while the top cover 2 is being installed, the pressure block 307 at the bottom of the top cover 2 will press down on the guide plate 301, causing the guide plate 301 to deform. This causes the moving blocks 303 connected at both ends to move the guide post 304 away from the guide plate 301. At the same time, the lower end of the moving block 303 will compress and deform the first spring plate 306, causing the moving block 303 to gradually move above the first spring plate 306 and gradually move towards the first spring plate 306. When the moving block 303 moves to the side away from the guide plate 301, after the first spring plate 306 moves away from the guide plate 301, the moving block 303 will drive the guide post 304 to continue sliding along the adjusting groove 302 and the rail groove 305, causing the middle part of the guide plate 301 to move downward, thereby pressing down on the guide and thus fixing it. At the same time, the push block 313 will also cooperate with the second spring plate 308 to squeeze the guide. At the same time, the lower ends of the upper extrusion blocks 314 on both sides of the push block 313 will also contact the lower extrusion block 309, thereby squeezing and pushing the lower extrusion block 309 to move closer to the second spring plate 308. At the same time, the lower extrusion block 309 will drive the slider 310 to slide along the second sliding groove 312. Simultaneously, the lower extrusion block 309 will squeeze the second spring plate 308 to deform, causing the middle part of the second spring plate 308 to bulge towards the push block 313, thereby increasing the squeezing force on the wire, further improving the clamping and fixing effect on the wire, thereby improving the wire anti-detachment effect, making the connection more stable, and more practical.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
