Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to an electrical plug-in connector for electrical engineering. Background Art

[0002] Electrical connection plays a vital role in many fields such as electronics, electrical engineering, and industrial production. In a broad sense, it refers to the collection of all electrical circuits in electrical products, including power connection components, power cords, internal wires, internal connection components, etc., while in a narrow sense, electrical connection refers to all ways to connect different conductors inside the product.

[0003] The patent with patent announcement number CN217215129U discloses an electrical plug-in connector, which clamps and fixes the cables to be connected through the cooperation of the wire seat and the wire pressing block in the guide groove, ensuring the stability of the cables when they are temporarily connected. After the two cables are fixed to the corresponding wire seats, the two wire seats are connected through the engagement of connector one and connector two, so that the cable ends in the wire seats are connected, and the wire pressing block that clamps the cable is limited by the spring limit pin to prevent the cable from falling off between the wire pressing block and the wire groove, thereby ensuring the stability during connection, and there is no need to cut the cable, so that the cable maintains its original length after temporary connection, so that it can be conveniently used for temporary wiring again.

[0004] However, during the implementation of the above solution, the staff is required to pull out the two limit pins and then manually push the two wire pressing blocks to move. It is troublesome to pull out the limit pins. When the cable is hard, it is also difficult to manually push the wire pressing blocks. In addition, the two wire holders are fixed by snap-fitting, which may easily lead to the loss of one of the wire holders during normal storage. Utility Model Content

DETAILED DESCRIPTION

[0018] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0019] Embodiment: An electrical plug-in connector for electrical engineering, such as Figure 1-Figure 4 As shown, it includes a U-shaped mounting plate 1, a fixing block 2, a cover plate 3, a limiting assembly and an extrusion assembly. The fixing blocks 2 are fixed to the U-shaped mounting plate 1 in a front-to-back staggered manner by bolts. The two fixing blocks 2 are respectively separated from the U-shaped mounting plate 1 into two staggered channels for inserting cables. The two channels are connected at the middle of the U-shaped mounting plate 1. A cover plate 3 is fixed between the tops of the two fixing blocks 2 by bolts. A limiting assembly for limiting and fixing the cable is arranged between the U-shaped mounting plate 1 and the cover plate 3. An extrusion assembly for extruding the end of the cable is arranged between the U-shaped mounting plate 1 and the limiting assembly.

[0020] like Figure 2 , Figure 3 and Figure 4As shown, the limiting assembly includes a U-shaped sliding rod 41, a limiting block 42, a trapezoidal block 43, a guide rod 44, a slider 45, an L-shaped push plate 46, a first fixed seat 47, a first screw rod 48 and a worm 49. The U-shaped mounting plate 1 is slidably connected to the front right side and the rear left side with the U-shaped sliding rod 41. The ends of the U-shaped sliding rod 41 are welded and fixed with the limiting block 42. The middle parts of the two U-shaped sliding rods 41 are welded and fixed with the trapezoidal block 43. The top of the cover plate 3 is welded and fixed with two guide rods 44 in a front-to-back offset manner. The two guide rods 44 are slidably connected with sliders 45. The two sliders 45 are welded and fixed with L-shaped push plates 46 on the side walls that are away from each other in the left and right directions. The two L-shaped push plates 46 are close to each other. One side of the adjacent trapezoidal block 43 is chamfered to facilitate the extrusion and pushing of the trapezoidal block 43. A first fixing seat 47 is symmetrically welded and fixed to the top of the cover plate 3. The two first fixing seats 47 are rotatably connected to the first screw rods 48. A worm 49 is welded and fixed between the ends of the two first screw rods 48. Since the worm 49 is fixedly connected between the two first screw rods 48, the two first screw rods 48 can only rotate synchronously. The two first screw rods 48 respectively penetrate the adjacent sliders 45 and cooperate with their threads. The threads on the two first screw rods 48 are set in reverse. In this way, when the two first screw rods 48 rotate synchronously, they can only push the two sliders 45 to move closer to or away from each other.

[0021] like Figure 2 and Figure 3 As shown, the extrusion assembly includes a slide rod 51, an extrusion block 52, a second fixed seat 53, a second screw rod 54, a worm gear 55 and a connecting rod 56. The slide rod 51 is symmetrically slidably arranged in the middle of the U-shaped mounting plate 1. The ends of the two slide rods 51 close to each other are welded and fixed with the extrusion block 52. The second fixed seat 53 is symmetrically welded and fixed in the middle of the top of the cover plate 3. The second screw rod 54 is rotatably connected between the two second fixed seats 53. The middle part of the second screw rod 54 is fixed with a worm gear 55 by a key connection. The worm gear 55 and the worm 49 are meshed with each other. The ends of the two slide rods 51 away from each other are welded and fixed with the connecting rod 56. The two ends of the second screw rod 54 respectively pass through the upper parts of the two connecting rods 56 and are respectively threaded with the two connecting rods 56.

[0022] First, the staff peels off a small section of the foreskin of the ends of the two cables to be connected to expose the metal wires of the cables, and then inserts the two cables into the two channels 31 of the connector respectively, ensuring that the ends of the exposed metal wires of the two cables are close to each other. Next, the staff rotates the first screw rod 48 by hand-tightening the nut, and the two first screw rods 48 respectively drive the two sliders 45 to slide along the two guide rods 44 in the direction away from each other, thereby driving the two L-shaped push plates 46 to approach the adjacent trapezoidal blocks 43, and gradually squeeze the two trapezoidal blocks 43, thereby pushing the two U-shaped sliding rods 41 to slide in the direction of the inside of the U-shaped mounting plate 1, so that the two cables are fixed at two points by the two limit blocks 42, so that The two cables are not easily pulled out. During the rotation of the two first screw rods 48, the worm 49 rotates along with the two first screw rods 48. Since the worm 49 is meshed with the worm wheel 55, the worm wheel 55 drives the second screw rod 54 to rotate. The second screw rod 54 then drives the two connecting rods 56 to move toward each other, thereby driving the two sliding rods 51 to also follow the two connecting rods 56 to move toward each other. In this way, the two extrusion blocks 52 respectively extrude the exposed ends of the metal wires of the two cables, so that the metal wire parts of the two cables can fit tightly together, thereby achieving a stable electrical connection. The two cables can be docked by simply rotating the first screw rod 48 by hand-tightening the nut, which saves time and effort.

[0023] like Figure 3 As shown, a partition plate 6 is also included. The partition plate 6 is clamped and fixed between the two fixing blocks 2, and the partition plate 6 is a metal plate.

[0024] By setting up the partition plate 6, when the two extrusion blocks 52 squeeze the ends of the exposed metal wires of the cables, the metal wires at the ends of the two cables will respectively fit into the partition plate 6. Since the partition plate 6 is a metal plate, the two cables can be electrically connected through the partition plate 6, and the metal wires at the ends of the two cables will not be entangled together, thereby facilitating the subsequent pulling out and separation of the two cables.

[0025] like Figure 3 As shown, a return spring 7 is also included, and a return spring 7 is connected between the two U-shaped sliding rods 41 and the U-shaped mounting plate 1.

[0026] By setting the return spring 7, when the two L-shaped push plates 46 move away from each other and gradually squeeze the trapezoid, the return spring 7 is gradually compressed. When the L-shaped push plate 46 releases the squeeze on the trapezoidal block 43, under the reset action of the return spring 7, the two U-shaped sliding rods 41 and the two trapezoidal blocks 43 can automatically move outward and reset, so as to facilitate the next cable docking.

[0027] like Figure 1 and Figure 4As shown, a protective shell 8 is also included, and the protective shell 8 is fixed between the U-shaped mounting plate 1 and the outer wall of the cover plate 3 by bolts.

[0028] By providing the protective housing 8, the first screw rod 48, the slider 45, the worm gear 55 and other components are surrounded and protected, so that these components can be prevented from being damaged by external factors, thereby improving the reliability and service life of the connector.

[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
