Description

Technical Field

[0001] The utility model relates to the technical field of connector terminals, in particular to a connector terminal with high stability. Background Art

[0002] Connector terminals, also known as terminal blocks, are accessories used to achieve electrical connections. They primarily transmit electrical signals or conduct electricity, making wire connections more convenient and quick.

[0003] Existing connector terminals typically secure wires to their wiring slots with screws or clamps. However, these screws or clamps reduce the contact area between the wire core and the conductive sheet within the wiring slot, resulting in unstable wire transmission and poor performance. Furthermore, during connection, the wire is easily affected by external forces and may fall out of the wiring slot, resulting in poor installation stability. Therefore, a highly stable connector terminal has been proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a connector terminal with high stability.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a highly stable connector terminal is designed, comprising a terminal housing, with a plurality of pairs of receiving slots being provided on both sides of the terminal housing, a connecting shaft being rotatably connected to one end of the top of each receiving slot, a connecting block being mounted on the side of each connecting shaft, one end of the connecting block extending above the receiving slot, a pressing plate being mounted on the top of each connecting block, the pressing plate covering the top opening of the receiving slot;

A locking screw is provided inside each mounting hole. A plurality of threaded holes are opened on the top of the terminal housing. The bottom of each locking screw extends into the corresponding threaded hole and engages with the thread of the threaded hole.

[0007] A first conductive sheet is installed at the bottom of each receiving groove, and the first conductive sheets in each pair of receiving grooves are electrically connected. A second conductive sheet is installed at the bottom of each pressure plate. A conductive tooth block is installed at the bottom of each second conductive sheet and the top of each first conductive sheet, and two adjacent conductive tooth blocks are staggered.

[0008] A plurality of second mounting plates are installed at both ends of the terminal housing, and the second mounting plates are located at the bottom of the corresponding receiving grooves, and a first mounting plate is installed at one end of each pressure plate, and a pair of fixing blocks are installed on the adjacent surfaces of each first mounting plate and the corresponding second mounting plate, and each pair of fixing blocks is connected by a cross bar, and the side of each cross bar is rotatably connected to a clamping plate, and the end of the clamping plate extends to one end of the receiving groove;

[0009] Elastic gaskets are installed on adjacent surfaces of the first mounting plate and the second mounting plate, and one side of the elastic gaskets is fixed on the side surface of the clamping plate.

[0010] Preferably, when the pressing plate covers the top opening of the accommodating groove, the distance between the proximal ends of two adjacent conductive tooth blocks is smaller than the size of the wire core.

[0011] Preferably, the edge of the pressing plate is loosely matched with the top edge of the accommodating groove.

[0012] Preferably, when the elastic gasket is not compressed and deformed, the distance between the adjacent ends of two adjacent card plates is smaller than the diameter of the wire.

[0017] By installing staggered conductive tooth blocks on the surfaces close to the first conductive sheet and the second conductive sheet, the core wire of the wire can be squeezed when the core wire is installed, so that the core wire is bent, increasing the contact area between the core wire and the first conductive sheet and the second conductive sheet, thereby increasing the connection stability and improving the use effect.

[0018] The elastic gasket can make the proximal ends of two adjacent clamping blocks abut against both sides of the wire, fix the wire in the accommodating groove, prevent the wire from falling off, and improve the installation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5 A high-stability connector terminal includes a terminal housing 1, and several pairs of accommodating grooves 9 are opened on both sides of the terminal housing 1. One end of the top of each accommodating groove 9 is rotatably connected to a connecting shaft 15. A connecting block 17 is installed on the side of each connecting shaft 15. One end of the connecting block 17 extends above the accommodating groove 9. A pressing plate 2 is installed on the top of each connecting block 17. The pressing plate 2 covers the top opening of the accommodating groove 9. The pressing plate 2 can rotate along the connecting shaft 15. After the core wire at the end of the wire is placed in the accommodating groove 9, the wire can be fixed in the accommodating groove 9 by rotating the pressing plate 2 to a horizontal position.

[0027] It should be noted that the edge of the pressing plate 2 is loosely matched with the top edge of the accommodating groove 9 , so that when the pressing plate 2 rotates along the connecting shaft 15 , the edge of the pressing plate 2 will not collide with the terminal housing 1 .

[0028] like Figure 1 and Figure 2 As shown, each pressure plate 2 is installed with a fixing plate 4 on both sides of one end away from the connecting block 17, a mounting hole 18 is provided on the top of the fixing plate 4, and a locking screw 8 is provided inside each mounting hole 18. A plurality of threaded holes 13 are provided on the top of the terminal housing 1, and the bottom of each locking screw 8 extends to the corresponding threaded hole 13 and is threadedly engaged with the threaded hole 13. In actual use, when the pressure plate 2 is rotated to a horizontal position, the mounting hole 18 is aligned with the corresponding threaded hole 13, and then one end of the locking screw 8 is passed through the mounting hole 18 and screwed into the threaded hole 13 to fix the pressure plate 2 on the terminal housing 1, so that the pressure plate 2 fixes the wire in the accommodating groove 9.

[0029] like Figure 2 and Figure 5 As shown, a first conductive sheet 14 is installed at the bottom of each accommodating groove 9, and the first conductive sheets 14 in each pair of accommodating grooves 9 are electrically connected, a second conductive sheet 19 is installed at the bottom of each pressure plate 2, and a conductive tooth block 10 is installed at the bottom of each second conductive sheet 19 and the top of each first conductive sheet 14, and the two adjacent conductive tooth blocks 10 are staggered. In actual use, when the pressure plate 2 is rotated to a horizontal position, the two adjacent conductive tooth blocks 10 will squeeze the core wire of the wire, thereby increasing the contact area between the core wire and the first conductive sheet 14 and the second conductive sheet 19, thereby improving the connection stability.

[0030] It should be noted that when the pressure plate 2 covers the top opening of the receiving groove 9, the distance between the adjacent ends of the two conductive tooth blocks 10 is smaller than the size of the wire core, so that the conductive tooth blocks 10 will squeeze the core wire of the wire. Figure 5 As shown, the core wire of the conductor will be wavy in the receiving groove 9, which can increase the contact area between the core wire and the first conductive sheet 14 and the second conductive sheet 19 (as shown in FIG. Figure 5 middle shadow area) to improve the connection effect.

[0031] like Figure 1 and Figure 4 As shown, several second mounting plates 6 are installed at both ends of the terminal housing 1, and the second mounting plates 6 are located at the bottom of the corresponding accommodating grooves 9, and a first mounting plate 5 is installed at one end of each pressing plate 2, and a pair of fixing blocks 12 are installed on the adjacent surfaces of each first mounting plate 5 and the corresponding second mounting plate 6. Each pair of fixing blocks 12 is connected by a cross bar 11, and the side of each cross bar 11 is rotatably connected to a card plate 7, and the end of the card plate 7 extends to one end of the accommodating groove 9. In actual use, the card plate 7 can be clamped on the upper and lower sides of the wire. When the wire falls off, the two adjacent card plates 7 will rotate relative to each other due to the tension of the wire, so that the distance between the adjacent ends of the two adjacent card plates 7 is reduced, and the wire can be tightly clamped and fixed to prevent the wire from falling off.

[0032] like Figure 3 and Figure 4 As shown, elastic gaskets 16 are installed on the adjacent surfaces of the first mounting plate 5 and the second mounting plate 6, and one side of the elastic gasket 16 is fixed to the side of the card plate 7. When the elastic gasket 16 is not compressed and deformed, the distance between the adjacent ends of the two adjacent card plates 7 is less than the diameter of the wire. Under the elastic force of the elastic gasket 16, one end of the card plate 7 can be tightly pressed against the side of the wire to fix the wire.

[0033] Specifically, when installing the present invention, the staff puts the core wire of the conductor into the receiving groove 9, then rotates the pressure plate 2 to a horizontal position, and then moves the locking screw 8 through the mounting hole 18 and into the threaded hole 13, and tightens the locking screw 8 to fix the pressure plate 2 on the terminal housing 1. At the same time, the conductive tooth block 10 on the second conductive sheet 19 cooperates with the conductive tooth block 10 on the first conductive sheet 14 to squeeze the core wire of the conductor (such as Figure 5 The core wire is fully in contact with the first conductive sheet 14 and the second conductive sheet 19, and the connection is firm. When the pressing plate 2 is rotated to a horizontal position, the proximal ends of the clamping plate 7 at the bottom of the first mounting plate 5 and the corresponding clamping plate 7 at the top of the second mounting plate 6 will both rest on the upper and lower sides of the wire to fix the wire. When the guide is fallen off by an external force, the two clamping plates 7 will be driven by the wire to rotate relative to each other, thereby reducing the distance between the proximal ends of the two clamping plates 7, thereby increasing the clamping force on the wire and preventing the wire from falling off.

[0034] Furthermore, a buffer rubber pad is provided at one end of the card plate 7 away from the cross bar 11 , and the buffer rubber pad can buffer the contact portion between the card plate 7 and the wire to prevent the wire surface from being damaged by the card plate 7 .

[0035] Furthermore, Figure 1 As shown, a reinforcing rib is installed on the top of each first mounting plate 5, which can increase the connection strength between the first mounting plate 5 and the pressure plate 2, and prevent the first mounting plate 5 from being deformed by force and affecting the fixing effect of the clamping plate 7.

[0036] Furthermore, Figure 1 As shown, a handle 3 is installed on the top of each locking screw 8, and the outer surface of the handle 3 is provided with anti-slip grooves. During the actual installation process, the staff can drive the locking screw 8 to rotate by turning the handle 3, thereby reducing the difficulty of tightening the locking screw 8.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
