Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically to a push-button connector. Background Technology

[0002] During electromechanical construction and maintenance, wires often need to be spliced. The existing splicing method mainly uses wrapping splicing and wrapping the splice with tape for protection. This method is prone to poor contact, high resistance at the connection point, and heat generation. Moreover, the tape is prone to aging and damage after long-term use. At the same time, this splicing method is prone to loosening at the splice when the wire is subjected to axial tension, which affects the safety and stability of power transmission.

[0003] Meanwhile, there are also terminal blocks on the market, which involve inserting the ends of the wires to be connected into the input and output terminals of the terminal block, and then pressing and fixing the ends of the wires with screws and washers. In actual installation, when overtightened, the wire cores of the terminal block are easily damaged or broken, resulting in poor wiring. At the same time, the wires are easily disturbed around the terminal block during use, and are more likely to break or loosen under the vibration of mechanical and electrical equipment.

[0004] Based on the above problems, the present invention proposes a push-button type connector. Summary of the Invention

[0005] To address the problems mentioned above in the technical background, the present invention aims to provide a press-type connector. By setting an elastic wire clamp, it can satisfy the need to press and fix wires of various diameters, and can also adjust the elastic pressing force to avoid excessive compression and damage to the wire core. At the same time, through the linkage design of the housing and the elastic wire clamp, the circuit is connected when the housing is closed, and the wires to be connected on both sides are clamped and fixed. This solves the problems mentioned in the background art, such as poor wiring, loosening under force, and excessive tightening of the connector to fix the wire end, which can cause damage to the wire core and breakage due to disturbance.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A push-button connector includes a terminal block and a cover. The terminal block is U-shaped, and elastic wire clamps are symmetrically slidably installed inside the terminal block. The cover is connected to the elastic wire clamps on both sides by two drive rods. When the cover moves downward, the drive rods push the elastic wire clamps on both sides to slide towards each other. Male and female connectors are respectively installed on the facing surfaces of the elastic wire clamps on both sides. When the cover is fastened to the terminal block, the male and female connectors are connected. A telescopic part is installed on the elastic wire clamp. When the elastic wire clamp slides towards the center, the telescopic part retracts downward. An elastic compression part with adjustable elasticity is slidably installed on the telescopic part. A wire core is inserted between the elastic compression part and the elastic wire clamp. When the telescopic part retracts downward, the elastic compression part fixes the wire core. Wire clamps for preventing wire displacement are symmetrically installed on both sides of the cover.

[0008] In the above technical solution, the wire cores to be connected are inserted into the elastic wire clamps on both sides. The clamping force of the elastic clamping part is adjusted according to the different diameters of the wire cores. When the cover is closed, the cover pushes the elastic wire clamps on both sides to slide towards each other through the drive rods on both sides. During the process of pushing the elastic wire clamps on both sides to slide towards each other, the telescopic part slides downward. The telescopic part pushes the elastic clamping part to elastically clamp and fix the wire cores. During the fastening process, the clamping parts on both sides of the cover clamp the wires on both sides to prevent slippage and avoid the impact caused by wire vibration or axial force. After the fastening is completed, the male and female heads on the facing surfaces of the elastic wire clamps on both sides are electrically connected. This achieves elastic clamping and fixing of wire cores with different diameters, and the clamping force can be adjusted. This method is simple to install and remove, the connection is safe, stable and reliable, and avoids wire core damage caused by excessive clamping. At the same time, it makes the wiring adaptable to different working environments.

[0009] Furthermore, the terminal block is symmetrically provided with first sliding grooves on both sides along the middle, and the bottom of the first sliding groove is connected to a second sliding groove that passes through the inner side. The two sliding wings included in the elastic wire clamp are respectively inserted into the second sliding grooves on both sides. The two traction shafts included in the elastic wire clamp are respectively inserted into the second sliding grooves and the first sliding grooves on both sides. The bottom end of the drive rod is inserted into the first sliding groove and rotatably mounted on the traction shaft. The terminal block base plate is symmetrically provided with third sliding grooves along the middle, and the front and rear groove surfaces of the third sliding groove are recessed with inclined sliding grooves. The top surface of the inclined sliding grooves is inclined towards the middle of the terminal block. The bottom end of the telescopic part is installed in the third sliding groove and the inclined sliding grooves on both sides.

[0010] Furthermore, the elastic wire clamping seat also includes a sliding seat. The traction shaft is symmetrically installed at one end of the sliding seat near the middle of the terminal block, and the sliding wing is symmetrically installed at the other end of the sliding seat. The middle of the sliding seat has a wire clamping groove and a through groove connected from top to bottom. The column included in the telescopic part is installed through the wire clamping groove and the through groove, and the diameter of the column is equal to the diameter of the through groove. The bottom end of the column is connected to a fixed shaft, and the two ends of the fixed shaft are respectively inserted into the inclined sliding grooves on both sides. At the same time, the two ends of the fixed shaft are symmetrically installed with rotating wheels.

[0011] In the above technical solution, the stability of the horizontal sliding of the sliding seat is increased by setting a sliding wing, so as to avoid the situation where the male and female heads are misaligned due to the end being tilted up by the force.

[0012] Furthermore, multiple anti-slip strips are installed in a ring on the sliding seat at the bottom of the wire pressing groove. One side of the wire pressing groove is connected to the first wire inlet groove that passes through the other end of the sliding seat. The other side of the wire pressing groove is recessed with an L-shaped copper plate groove. The inner end of the sliding seat is symmetrically provided with insertion plate grooves. An insertion plate is inserted into the inner end of the sliding seat. One side of the insertion plate is inserted into the two insertion plate grooves through an L-shaped insertion block. The middle of the insertion plate is provided with a positioning hole for installing the male or female connector. A copper plate for connecting the male or female connector is installed in the copper plate groove. An elastic extrusion part is installed above the column to extrude and fix the wire core installed in the wire pressing groove.

[0013] Furthermore, a cross groove is provided on the top of the column, the cross groove is coaxial with the column, and the top of the cross groove is connected to a threaded hole penetrating the top of the column. The elastic compression part includes a compression part, an elastic element, and a compression adjustment part. The compression adjustment part is installed on the threaded hole, the elastic element is installed in the cross groove below the threaded hole, and the compression part is slidably installed on the cross groove below the elastic element. At the same time, the top of the operating rod included in the compression part penetrates the elastic element and the compression adjustment part. During the downward contraction of the column, the compression adjustment part pushes and compresses the elastic element, and finally the elastic element pushes the compression part to compress the wire core. The compression adjustment part is used to adjust the compression force of the elastic element when the male and female heads are connected.

[0014] In the above technical solution, the height of the top of the elastic element is adjusted by the extrusion adjustment part. During the process of the column moving from one side to near the middle of the terminal block, the spatial extension height of the column is fixed, that is, the spatial extension height of the extrusion part is fixed. Before contraction, the height of the elastic element is controlled to be lowered by the extrusion adjustment part. After contraction at the fixed height between the column and the extrusion part, it is equivalent to increasing the extrusion deformation length of the elastic element when it is closed and installed, thereby increasing the extrusion pressure, and conversely, decreasing the extrusion pressure.

[0015] Furthermore, the compression adjustment part includes a threaded cylinder installed on the threaded hole, the top end of the threaded cylinder is provided with a nut, the bottom end of the threaded cylinder is provided with a compression pad, and the bottom surface of the compression pad compresses the top end of the elastic element.

[0016] Furthermore, the extrusion part includes an extrusion ring, and a cross slider is connected to the inner side of the extrusion ring. The cross slider is slidably installed in the cross groove. Multiple lower anti-slip strips are evenly provided on the bottom surface of the extrusion ring. An operating rod is connected to the center of the top surface of the cross slider. The top end of the operating rod passes through the elastic element, the extrusion pad, the threaded cylinder and the nut in sequence. A rod cap is installed on the top end of the operating rod.

[0017] In the above technical solution, the operation lever and lever cap are designed to facilitate the installation of the wire core. By manually lifting the operation lever, the cross slider and the extrusion ring are raised, thereby increasing the space between the extrusion ring and the bottom of the wire groove, which facilitates the winding and insertion of the wire core.

[0018] Furthermore, the cover includes a U-shaped main cover plate, with both ends of the main cover plate inserted into both ends of the terminal block. Symmetrically arranged second wire inlet grooves are provided on both sides of the main cover plate. Symmetrically arranged upper anti-slip teeth with upward-pointing angles are provided on the inner side of the side plates on both sides of the second wire inlet grooves. Symmetrically arranged unlocking blocks are provided on the outer side of the side plates on both sides of the second wire inlet grooves. Lower anti-slip teeth are provided below both ends of the terminal block, engaging with the upper anti-slip teeth. Lifting the unlocking blocks at both ends opens the two sides of the main cover plate, thereby separating the lower anti-slip teeth from the upper anti-slip teeth. Side guard plates are symmetrically installed on the front and rear sides of the main cover plate, with both ends of the side guard plates extending beyond the sides of the main cover plate. Limiting protrusions are provided on the inner sides of both ends of the front and rear side guard plates. Rotating seats are symmetrically arranged at the four corners of the inner top plate of the main cover plate, with the top ends of the four drive rods rotatably mounted on the rotating seats.

[0019] Furthermore, the front and rear side guard plates are symmetrically provided with guide rail grooves, and the front and rear sides of the terminal block are symmetrically provided with guide rails. When the cover is fastened onto the terminal block, the guide rails are inserted into the corresponding guide rail grooves.

[0020] In the above technical solution, in order to avoid tilting of the main cover plate during the fastening process, the cover body is stably and parallelly fastened to the terminal block by setting guide rails and guide rail grooves during the fastening process of the terminal block, which improves the accuracy and stability of the connection.

[0021] Furthermore, the clamping part is installed on the inner side of the side plate on both sides of the second wire inlet groove. The clamping part includes two clamping blocks symmetrically installed on both sides of the second wire inlet groove. The two clamping blocks are symmetrically provided with multiple rubber teeth facing each other, and the tooth angles of the rubber teeth face the center of the main cover plate.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] This invention features symmetrically slidably mounted elastic wire clamps within a terminal block. Two drive rods connect the elastic wire clamps on both sides of the cover. When the cover moves downwards, the drive rods push the elastic wire clamps on both sides to slide towards each other. Male and female connectors are respectively mounted on the facing surfaces of the elastic wire clamps. When the cover is fastened to the terminal block, the male and female connectors connect. A telescopic part is mounted on the elastic wire clamp. When the elastic wire clamp slides towards the center, the telescopic part retracts downwards. An adjustable elastic compression part is slidably mounted on the telescopic part. A wire core is inserted between the elastic compression part and the elastic wire clamp. When the telescopic part retracts downwards, the elastic compression part secures the wire core. symmetrically mounted wire clamps on both sides of the cover prevent wire displacement.

[0024] Insert the wire cores of the wires to be connected into the elastic clamping seats on both sides. Adjust the clamping force of the elastic clamping part according to the diameter of the wire cores. When closing the cover, the cover pushes the elastic clamping seats on both sides to slide towards each other via the drive rods on both sides. During the sliding of the elastic clamping seats towards each other, the telescopic part slides downward, pushing the elastic clamping part to elastically clamp and fix the wire cores. During the fastening process, the clamping parts on both sides of the cover provide anti-slip clamping for the wires on both sides, avoiding the impact caused by wire vibration or axial force. After fastening, the male and female connectors on the facing surfaces of the elastic clamping seats on both sides are electrically connected. This achieves elastic clamping and fixing of wire cores with different diameters, and the clamping force can be adjusted. This method is simple to install and remove, the connection is safe, stable and reliable, and avoids wire core damage caused by excessive clamping. At the same time, it makes the wiring adaptable to different working environments. Attached Figure Description

[0041] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0042] like Figure 1-12 As shown, a push-button connector includes a terminal block 100 and a cover 300. Both the terminal block 100 and the cover 300 are made of rigid PVC, enhancing safety. The terminal block 100 is U-shaped, with symmetrically slidably mounted elastic wire clamps 200 inside. The cover 300 has two drive rods 600 connecting the elastic wire clamps 200 on each side. When the cover 300 moves downwards, the drive rods 600 push the elastic wire clamps 200 to slide towards each other. Male connectors 400 and female connectors 500 are respectively mounted on the facing surfaces of the elastic wire clamps 200. When the cover 300 is fastened onto the terminal block 100, the male connectors 400 and 500 are connected. During fastening, the four drive rods 600 rotate and retract into the first sliding grooves 101 symmetrically provided on the side plates of the terminal block 100. The elastic wire clamps 200... The cover 300 is equipped with a telescopic part. When the elastic wire clamp 200 slides towards the center, the telescopic part retracts downward. An elastic compression part with adjustable elasticity is slidably installed on the telescopic part. A wire core is inserted between the elastic compression part and the elastic wire clamp 200. When the telescopic part retracts downward, the wire core is fixed by the elastic compression part. The cover 300 is symmetrically equipped with wire clamping parts on both sides to prevent the wires from moving outward. During the fastening process, the wire clamping parts on both sides of the cover anti-slip clamps the wires on both sides to avoid the impact caused by wire vibration or axial force. When the cover 300 is snapped onto the terminal block 100 to complete the installation, the two drive rods 600 on both sides push the two elastic wire clamps 200 to the center of the terminal block 100 respectively. At the same time, the male connector 400 and the female connector 500 are inserted. The telescopic part drives the elastic compression part to retract, thereby realizing the closed linkage to connect the circuit while squeezing and fixing the wire cores on both sides.

[0043] In this embodiment, the wire cores to be connected are inserted into the elastic wire clamps 200 on both sides. The clamping force of the elastic clamping part is adjusted according to the different diameters of the wire cores. When the cover 300 is installed, the cover 300 pushes the elastic wire clamps 200 on both sides to slide towards each other through the drive rods 600 on both sides. During the process of pushing the elastic wire clamps 200 on both sides to slide towards each other, the telescopic part slides downward. The telescopic part pushes the elastic clamping part to elastically clamp and fix the wire cores. During the fastening process, the clamping parts on both sides of the cover 300 clamp the wires on both sides to prevent slippage and avoid the impact caused by wire vibration or axial force. After the fastening is completed, the male and female heads on the facing surfaces of the elastic wire clamps on both sides are electrically connected. This achieves elastic clamping and fixing of wire cores with different diameters, and the clamping force can be adjusted. This method is simple to install and remove, the connection is safe, stable and reliable, and avoids wire core damage caused by excessive clamping. At the same time, it makes the wiring adaptable to different working environments.

[0044] like Figure 6-8As shown, the terminal block 100 has symmetrical first sliding grooves 101 on both side plates along the middle. The bottom of the first sliding groove 101 is connected to the second sliding groove 102 that passes through the inner side. The first sliding groove 101 and the second sliding groove 102 are set to ensure the stability of the sliding of the elastic wire clamp 200. The two sliding wings 220 included in the elastic wire clamp 200 are respectively inserted into the second sliding grooves 102 on both sides. The two traction shafts 230 included in the elastic wire clamp 200 are respectively inserted into the second sliding grooves 102 and the first sliding groove 101 on both sides. The bottom end of the drive rod 600 is inserted into the first sliding groove 101 and rotatably mounted on the traction shaft 230. During the folding and fastening process of the cover 300, the bottom end of the drive rod 600 is pushed to retract and fold into the first sliding groove 101 in the middle. At the same time, the drive rod 600 pushes the elastic wire clamp 200 to move in the middle. On the one hand, it realizes the function of driving the male connector 400 and the female connector 500 to make an electrical connection. On the other hand, it provides power for the extension and retraction of the telescopic part.

[0045] The base plate of the terminal block 100 is symmetrically provided with a third slide groove 103 from the middle to both sides. The front and rear surfaces of the third slide groove 103 are recessed with inclined slide grooves 104. The top surface of the inclined slide grooves 104 is inclined to the middle of the terminal block 100. The bottom end of the telescopic part is installed in the third slide groove 103 and the inclined slide grooves 104 on both sides. As the telescopic part slides towards the middle along with the elastic wire pressing seat 200, it is restricted by the pressure of the top inclined surface of the inclined slide groove 104 and contracts to the bottom, thereby achieving the contraction function.

[0046] like Figure 6-8 As shown, the elastic wire clamping seat 200 also includes a sliding seat 210. A traction shaft 230 is symmetrically installed at one end of the sliding seat 210 near the middle of the terminal block 100. A sliding wing 220 is symmetrically installed at the other end of the sliding seat 210. A wire clamping groove 211 and a through groove 212 are provided in the middle of the sliding seat 210 from top to bottom. The column 260 included in the telescopic part is installed through the wire clamping groove 211 and the through groove 212. The diameter of the column 260 is equal to the diameter of the through groove 212. A fixed shaft 261 is connected to the bottom end of the column 260. The two ends of the fixed shaft 261 are respectively inserted into the inclined sliding grooves 104 on both sides. At the same time, a rotating wheel 262 is symmetrically installed at both ends of the fixed shaft 261. The sliding resistance is reduced by setting the rotating wheel 262.

[0047] By setting the sliding wing 220, the stability of the horizontal sliding of the sliding seat 210 is increased, and the situation that the male head 400 and female head 500 are not aligned due to the inner end being lifted by force is avoided.

[0048] like Figure 9 , 10As shown, multiple lower anti-slip strips 240 are installed in a ring on the sliding seat 210 at the bottom of the wire pressing groove 211 to increase the anti-slip performance of the pressed wire core. One side of the wire pressing groove 211 is connected to the first wire inlet groove 214 that passes through the other end of the sliding seat 210. The wire core is inserted through the first wire inlet groove 214. The other side of the wire pressing groove 211 is recessed with an L-shaped copper plate groove 213. The inner end of the sliding seat 210 is symmetrically provided with insertion plate grooves 215. An insert plate 250 is inserted into the inner end of the 10. One side of the insert plate 250 is inserted into two insert plate slots 215 through an L-shaped insert block 251. The middle of the insert plate 250 is provided with a positioning hole 252 for installing a male connector 400 or a female connector 500. A copper sheet 253 for connecting the male connector 400 or the female connector 500 is installed in the copper sheet slot 213. An elastic extrusion part is installed above the column 260 to extrude and fix the wire core installed in the wire pressing slot 211.

[0049] The sliding insert plate 250 facilitates the disassembly and maintenance of the male connector 400 or the female connector 500. At the same time, the L-shaped insert block 251 and the insert plate groove 215 design increase the stability of the installation. Meanwhile, the main cover plate 310 can hold the top of the insert plate 250 to prevent it from falling out when it is installed, thereby increasing the safety and stability of the installation.

[0050] like Figure 11 , 12 As shown, a cross groove 263 is provided above the column 260. The elastic extrusion part is installed by setting the cross groove 263 to increase the uniformity and stability of its sliding extrusion. The cross groove 263 is coaxial with the column 260. The top of the cross groove 263 is connected to the threaded hole 264 that passes through the top of the column 260. The elastic extrusion part includes an extrusion part, an elastic element 280 and an extrusion adjustment part. The elastic element 280 is a spring or an elastic rubber cylinder. The extrusion adjustment part is installed on the threaded hole 264. The elastic element 280 is installed in the cross groove 263 below the threaded hole 264. The extrusion part is slidably installed on the cross groove 263 below the elastic element 280. At the same time, the top of the operating rod 292 included in the extrusion part passes through the elastic element 280 and the extrusion adjustment part. During the downward contraction of the column 260, the extrusion adjustment part pushes the extrusion elastic element 280 to extrude. Finally, the elastic element 280 pushes the extrusion part to extrude the wire core. The extrusion adjustment part is used to adjust the extrusion force of the elastic element 280 when the male head 400 and the female head 500 are connected.

[0051] The height of the top of the elastic element is adjusted by the compression adjustment part. During the process of the column 260 moving from one side to near the middle of the terminal block 100, the spatial extension height of the column 260 is fixed, that is, the spatial extension height of the compression part is fixed. Before contraction, the height of the elastic element 280 is controlled to be lowered by the compression adjustment part. After contraction at the fixed height of the column 260 and the compression part, it is equivalent to increasing the compression deformation length of the elastic element 280 when it is closed and installed, thereby increasing the compression pressure, and conversely decreasing the compression pressure.

[0052] like Figure 11 , 12 As shown, the compression adjustment unit includes a threaded cylinder 270 installed on the threaded hole 264. The top end of the threaded cylinder 270 is provided with a nut 271, and the bottom end of the threaded cylinder 270 is provided with a compression pad 272. The bottom surface of the compression pad 272 compresses the top end of the elastic member 280. The height of the compression pad 272 at the bottom end of the threaded cylinder 270 is controlled by rotating the nut 271, thereby controlling the total deformation of the elastic member 280.

[0053] like Figure 11 As shown, the extrusion section includes an extrusion ring 290, a cross slider 291 connected to the inner side of the extrusion ring 290, the cross slider 291 being slidably installed in the cross groove 263, a plurality of lower anti-slip strips 294 being evenly provided on the bottom surface of the extrusion ring 290, an operating rod 292 being connected to the center of the top surface of the cross slider 291, the top of the operating rod 292 passing through an elastic element 280, an extrusion pad 272, a threaded cylinder 270 and a nut 271 in sequence, and a rod cap 293 being installed on the top of the operating rod 292;

[0054] The operation lever 292 and lever cap 293 are designed to facilitate the installation of the wire core. By manually lifting the operation lever 292, the cross slider 291 and the compression ring 290 are raised, thereby increasing the space between the compression ring 290 and the bottom surface of the wire pressing groove 211, which facilitates the winding and insertion of the wire core.

[0055] like Figure 1-5 As shown, the cover 300 includes a U-shaped main cover plate 310, with both ends of the main cover plate 310 inserted into both ends of the terminal block 100. Symmetrically arranged second wire inlet grooves 311 are provided on both side plates of the main cover plate 310. Symmetrically arranged upper anti-slip teeth 330 with upward-pointing teeth are provided on the inner side of the side plates on both sides of the second wire inlet grooves 311. Symmetrically arranged unlocking blocks 312 are provided on the outer side of the side plates on both sides of the second wire inlet grooves 311. Lower anti-slip teeth 120 are provided below both ends of the terminal block 100, engaging with the upper anti-slip teeth 330. Through this tooth design, a... On the one hand, it is easy to insert, and on the other hand, it can be disengaged when unlocking. By lifting the unlocking blocks 312 at both ends, the two side plates of the main cover plate 310 are opened, thereby separating the lower anti-slip teeth 120 and the upper anti-slip teeth 330. The main cover plate 310 is symmetrically equipped with side guard plates 350 on the front and rear sides. The two ends of the side guard plates 350 extend out of the two sides of the main cover plate 310. The two ends of the front and rear side guard plates 350 are provided with limiting protrusions 352 facing inward. By setting the limiting protrusions 352, damage to the structure caused by excessive lifting angle at the end of the main cover plate 310 is avoided.

[0056] The inner top plate of the main cover plate 310 is symmetrically provided with rotating seats 320 at the four corners, and the top ends of the four drive rods 600 are rotatably mounted on the rotating seats 320 one by one.

[0057] like Figure 1-4As shown, guide rail grooves 351 are symmetrically provided on the front and rear side guard plates 350, and guide rails 110 are symmetrically provided on the front and rear sides of the terminal block 100. When the cover 300 is fastened onto the terminal block 100, the guide rails 110 are inserted into the guide rail grooves 351 respectively. In order to avoid the main cover plate 310 tilting during the fastening process, the guide rails 110 and guide rail grooves 351 are set to ensure that the cover 300 can be stably and parallelly fastened onto the terminal block 100, thereby improving the accuracy and stability of the connection.

[0058] like Figure 4 , 5 As shown, a wire clamping part is installed on the inner side of the side plates on both sides of the second wire inlet groove 311. The wire clamping part includes two clamping blocks 340 symmetrically installed on both sides of the second wire inlet groove 311. The two clamping blocks 340 are symmetrically provided with multiple rubber teeth 341 facing each other. The bottom of the multiple rubber teeth 341 on both sides is provided with a bucket-shaped bevel to facilitate the insertion of the wire during clamping. The tooth angle of the rubber teeth 341 faces the center of the main cover plate 310. With this tooth angle setting, when the wire slides towards the center, it squeezes the multiple rubber teeth 341 on both sides to deform towards the center and inward. The multiple rubber teeth 341 will not affect the movement of the wire. When the wire is subjected to an axial force on the outside after installation, the multiple rubber teeth 341 will not deform towards the center due to friction to prevent the wire from coming out. It can effectively protect and prevent the influence of axial force and vibration on the wire core crimping.
