Description

A wiring harness terminal plug-in device for a power distribution cabinet

Technical Field

The invention relates to the technical field of power distribution cabinet assembly, in particular to a wiring harness terminal plug-in device for a power distribution cabinet.

Background Art

The distribution cabinet is an important part of the power system, used to receive, distribute and control electrical energy. It is usually installed on construction sites, commercial or residential buildings to ensure efficient and safe transmission of electricity. Various electronic components for assisting in the control of electrical energy are installed in the distribution cabinet, such as circuit breakers, relays, mutual inductors and indicating instruments. Such electronic components are usually connected through wiring harness cables. The main connection method is to plug the two ends of multiple wiring harnesses into the corresponding terminal blocks respectively, and then connect them between the corresponding two components through the terminal blocks.

At present, when performing the plug-in operation of the wiring harness terminals, the main method is to manually plug one end of the multiple wiring harnesses into each terminal on the corresponding terminal row, and then manually tighten the screws on the terminal to complete the fixing and pressing of all the wiring harnesses. Then, the other end of the wiring harness is cut according to the required connection distance between the two components, and then the above plug-in process is repeated to complete the plug-in operation of the other end of the wiring harness. However, when the number of wiring harnesses required to be plugged in is large, the overall plug-in process is cumbersome, time-consuming and labor-intensive, and the plug-in efficiency is low. At the same time, when the insertion and release of multiple wiring harnesses are not guided and controlled, it is easy to have the problem that some wiring harnesses are not effectively plugged in, which requires manual adjustment, further reducing the overall plug-in efficiency.

In view of the above problems, solutions have also been proposed in the prior art. For example, a Chinese invention patent with publication number CN118249162B discloses a wiring harness terminal plug-in device for an energy storage distribution cabinet. The device limits and fixes the wiring harness located in the placement groove through a placement unit, so that the axis of the wiring harness is colinear with the axis of the semicircular segment of the placement groove. The wiring harness is center-limited by a limit group, and the guide column is plugged in with the corresponding mounting hole, so that the wiring harness is aligned with the corresponding socket on the terminal row for guidance control.

However, the above-mentioned plug-in device is only applicable to the plug-in operation of a single end of the same wire harness. When facing the double-end plug-in operation of the same wire harness, the entire process of the single-end plug-in operation needs to be repeated, which reduces the overall operation efficiency; secondly, whether it is a single-end or double-end plug-in operation, the wire harness cannot be axially straightened during the plug-in process of the wire harness and the terminal block. At the same time, in the double-end plug-in operation, the length between the terminal blocks at both ends is difficult to control in advance, and it is easier for the wire harness to be too long or too short; furthermore, after the plug-in is completed, it is difficult to quickly disassemble and separate the placement unit from the wire harness, which will further affect the overall efficiency.

DETAILED DESCRIPTION

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

As shown in FIG1 , a wiring harness terminal plug-in device for a power distribution cabinet comprises: a platform bracket 1, wherein a transverse groove is provided on the lower end surface of the platform bracket 1, and two left-right symmetrical L-shaped frames 2 are provided in the transverse groove for sliding left and right, and the horizontal sections of the two L-shaped frames 2 are arranged opposite to each other, and a fixing unit 3 for fixing the terminal row is provided on the L-shaped frame 2.

As shown in Figures 1, 2, 3 and 7, the platform bracket 1 is provided with a plug-in mechanism 4, which includes a T-shaped plate 40, a T-shaped plate 40 located between the two L-shaped frames 2 is slidably arranged in the transverse groove, a wire clamping assembly 41 is fixedly arranged on the lower end surface of the T-shaped plate 40, a receiving groove is provided on the right end surface of the horizontal section of the T-shaped plate 40, a movable plate 420 with its right end tilted upward from left to right is slidably arranged in the receiving groove, and a hinged plate 421 is hingedly connected to the inclined surface of the movable plate 420, and the hinged plate 4 A rectangular plate 422 is fixedly provided on the lower end surface of 21, and a wire clamping assembly 41 is also clamped and installed on the rectangular plate 422. The wire clamping assembly 41 includes a fixing plate 410 and a mounting plate 411 that are relatively arranged. The fixing plate 410 in the wire clamping assembly 41 on the T-shaped plate 40 is fixedly connected to the vertical section of the T-shaped plate 40. Both fixing plates 410 are provided with a wire pressing group for implementing wire clamping and a guide unit 44 for guiding the wiring harness plug-in. The guide unit 44 includes a guide column 440 that cooperates with the mounting holes on both sides of the terminal block.

As shown in FIG. 1 and FIG. 3 , the T-shaped plate 40 is provided with an adjusting unit 5 for adjusting the length of the patch cord by adjusting the extended length of the movable plate 420 . The adjusting unit 5 includes a bolt 50 for locking the movable plate 420 and the hinged plate 421 .

It should be noted that the platform bracket 1 is fixedly arranged on an existing external base, so that there is more working space under the platform bracket 1. When working, the staff first places the two terminal rows that need to be plugged into the wiring harness on the L-shaped frame 2 respectively, and clamps and fixes the terminal rows through the fixing unit 3 to facilitate subsequent plug-in installation. After that, the staff places the wiring harness that needs to be plugged in between the fixed plate 410 and the mounting plate 411 in the wire clamping assembly 41 on the T-shaped plate 40, and uses the corresponding wire pressing group to make the fixed plate 410 and the mounting plate 411 cooperate with each other to clamp and limit the multiple wire harnesses, and then clamps the other end of the wire harness between the fixed plate 410 and the mounting plate 411 in another wire clamping assembly 41, and limits it through the corresponding wire pressing group.

Move the movable plate 420 and the hinged plate 421 so that the distance between the right end of the hinged plate 421 and the T-shaped plate 40 is equal to the length of the required wiring harness minus the length required for plug-in (i.e., the length required for insertion into the terminal), and lock the position of the movable plate 420 through bolts 50, and then the fixed plate 410 in the other wire clamping assembly 41 is clamped to the rectangular plate 422 by plug-in and clamping. In this process, the fixed plate 410 and the mounting plate 411 in the wire clamping assembly 41 are moved while the wiring harness is straightened. Then, the hinged plate 421 is rotated and locked by the adjustment unit 5. Finally, the hinged plate 421 and the movable plate 420 are parallel. At this time, the two wire clamping assemblies 41 are distributed left and right and the wiring harness is horizontally stretched, as shown in the lower side view in Figure 7.

Move the T-shaped plate 40 so that the left end of the wiring harness is inserted into the terminal on the left. The staff locks the wiring harness by tightening the screws on the terminal. Then, move the left L-shaped frame 2 and the T-shaped plate 40 at the same time so that the right end of the wiring harness is inserted into the right terminal. Tighten the bolts on the right terminal to lock the wiring harness. Finally, take out the wiring harness and the terminal to complete the plug-in operation. Secondly, in the above process, the wiring harness plug-in operation is guided by inserting the guide column 440 in the guide unit 44 into the mounting hole on the adjacent terminal row.

As shown in Figures 1 and 2, the fixing unit 3 includes a fixing block 30, and two front-to-back symmetrical fixing blocks 30 are fixedly arranged on the upper end surface of the horizontal section of the L-shaped frame 2. A clamping rod 31 with an axis extending from front to back is slidably installed on the fixing block 30 and penetrates through it. A clamping plate 32 is fixedly arranged on the opposite surfaces of the two front-to-back opposite clamping rods 31, and a spring 33 mounted on the corresponding clamping rod 31 is fixedly arranged between the clamping plate 32 and the fixing block 30. The two clamping plates 32 on the same L-shaped frame 2 are symmetrical front-to-back, and the front clamping plate 32 is a straight section and an inclined section inclined forward from left to right from left to right.

When working, the terminal row is placed on the horizontal section of the L-shaped frame 2 in a state parallel to the horizontal section of the L-shaped frame 2, and the terminal rows on the two L-shaped frames 2 are symmetrical. During the placement process, the terminal row first contacts the inclined section of the clamping plate 32, and the two front and rear opposite clamping plates 32 are moved away from each other by squeezing the inclined section of the clamping plate 32, and the spring 1 33 is compressed. When the terminal row moves to contact the straight section of the clamping plate 32, the elastic force generated by the deformation of the spring 1 33 makes the clamping plate 32 press against the terminal row, and the terminal row is elastically clamped, which is convenient for the subsequent plug-in of the wiring harness and also convenient for the quick removal of the terminal row after the plug-in is completed, thereby improving the overall plug-in efficiency.

As shown in Figure 3, the wire pressing group located on the T-shaped plate 40 includes a bolt 43. The lower end surface of the fixed plate 410 corresponding to the wire pressing group is fixed with two bolts 43 that are symmetrical front and back and have vertical axes. The bolts 43 pass through the corresponding mounting plate 411. The threads on the bolts 43 are matched with nuts 430 that are matched with the threads and are used to clamp the wiring harness.

As shown in Figures 3 and 4, the wire pressing group corresponding to the wire clamping assembly 41 on the rectangular plate 422 includes a hinged column 431, and the left end face of the corresponding fixed plate 410 is hinged with two front-to-back symmetrical hinged columns 431 with horizontal axes, and the front and rear end faces of the corresponding mounting plate 411 are both provided with clamping grooves, and a mounting block 432 is provided on the hinged column 431 for left and right sliding sleeves, and the mounting block 432 and the left end face of the hinged column 431 are fixed together with a spring 2 433 through a connecting block.

As shown in FIG. 4 , the opposite surfaces of the fixing plate 410 and the corresponding mounting plate 411 are fixedly provided with a plurality of triangular strips 45 made of rubber and distributed equidistantly along the width direction of the fixing plate 410 .

During operation, the staff will sequentially place the multiple wiring harnesses that need to be plugged in between the fixing plate 410 and the mounting plate 411 corresponding to the T-shaped plate 40, and arrange the wiring harnesses equidistantly from front to back, and then manually tighten the nut 430, so that the mounting plate 411 presses the wiring harness onto the fixing plate 410 through the cooperation between the nut 430 and the corresponding bolt 43, thereby completing the wire pressing operation of the wire clamping assembly 41, pressing and fixing the left side of the multiple wiring harnesses, and at this time, the parts of the multiple wiring harnesses located on the right side of the vertical section of the T-shaped plate 40 are free to face vertically downward, and then work The personnel place the fixed plate 410 and the mounting plate 411 in another wire clamping assembly 41 on the left and right sides of the wiring harness respectively, and the fixed plate 410 is located on the right side of the wiring harness, and rotate the hinge column 431 so that the hinge column 431 is clamped into the corresponding clamping groove. During this process, the mounting block 432 is away from the fixed plate 410, and the spring 2 433 is compressed. When the hinge column 431 is perpendicular to the fixed plate 410, the elastic force generated by the compression of the spring 2 433 causes the mounting block 432 to push the mounting plate 411, and finally the mounting plate 411 and the fixed plate 410 press the corresponding wiring harness.

Secondly, during the wire pressing process of the above-mentioned mounting plate 411 and the fixing plate 410, the mounting plate 411 and the fixing plate 410 press the wire harness and cause the triangular bar 45 to deform. Therefore, the friction between the fixing plate 410, the mounting plate 411 and the wire harness is increased by deforming multiple triangular bars 45, thereby improving the limiting effect of the wire harness.

After completing the wiring harness plug-in process, the mounting plate 411 in the wire clamping assembly 41 on the T-shaped plate 40 can be disassembled after removing the nut 430, and the corresponding mounting plate 411 in the other wire clamping assembly 41 can be disassembled by rotating the hinge column 431. Therefore, the above method ensures the limit clamping of the two ends of the wiring harness while facilitating the subsequent disassembly process, thereby improving the plug-in efficiency and facilitating the subsequent resetting and re-plugging of the wiring harness.

As shown in Figures 1, 5 and 6, the plug-in mechanism 4 also includes a plug-in column 46, and the left end face of the rectangular plate 422 is penetrated by a plug-in groove 460 with an axis extending from left to right. The plug-in groove 460 is rectangular segment one, circular segment and rectangular segment two from front to back. The right end face of the fixed plate 410 in the wire clamping assembly 41 corresponding to the rectangular plate 422 is rotatably provided with a plug-in column 46 with an axis extending from left to right, and two front-to-back symmetrical limit blocks 461 are fixedly provided on the plug-in column 46.

As shown in Figures 1 and 3, the adjustment unit 5 includes a connecting groove 51, and the front end surface of the horizontal section of the T-shaped plate 40 is provided with a connecting groove 51 connected to the accommodating groove. There are two bolts 50 and the bolts 50 are fixedly arranged on the movable plate 420. After the front end of the bolt 50 passes through the connecting groove 51, a nut 510 for locking the movable plate 420 is threadedly installed.

As shown in Figures 2, 3 and 6, the adjustment unit 5 also includes an L-shaped plate 52, the upper end surface of the horizontal section of the T-shaped plate 40 is fixedly provided with the L-shaped plate 52, the right end surface of the horizontal section of the L-shaped plate 52 is provided with a support groove 520, the right end surface of the hinged plate 421 is rotatably provided with a support column 521, two front-to-back symmetrical support blocks 522 are fixedly provided on the support column 521, a volute spring 523 is fixedly provided between the support column 521 and the hinged plate 421, and an avoidance groove 524 for avoiding the L-shaped plate 52 is provided in the vertical section of the right side L-shaped frame 2.

During operation, after both wire clamping assemblies 41 have completed the wire pressing operation, the fixed plate 410 and the mounting plate 411 corresponding to the plug-in column 46 as a whole and the wiring harness portion located on the right side of the mounting plate 411 corresponding to the T-shaped plate 40 are naturally hung, and the hinge plate 421 is rotated to keep the hinge plate 421 in a horizontal state, and the movable plate 420 and the hinge plate 421 are moved according to the required length of the plug-in wiring harness, and the distance between the right end of the horizontal hinge plate 421 and the vertical section of the T-shaped plate 40 is equal to the length of the wiring harness after deducting the necessary plug-in length, and then the staff tightens the nut 510 to the corresponding The bolt 50 is mounted on the movable plate 420 through the cooperation between the two bolts 50 and the nuts, and then the hinge plate 421 is loosened, and the hinge plate 421 returns to its initial vertical state. The plug-in column 46 is moved by manually holding the plug-in column 46 and the clamping column is inserted from left to right into the plug-in groove 460 on the rectangular plate 422. When the limit block 461 moves to the right side of the rectangular plate 422, the plug-in column 46 is rotated so that the two limit blocks 461 are staggered with the rectangular segment 1 and the rectangular segment 2 of the plug-in groove 460 respectively, so that the corresponding fixed plate 410 is plugged and installed on the rectangular plate 422.

It should be noted that the distance between the limit block 461 on the plug-in column 46 and the corresponding fixing plate 410 is the same as the length of the plug-in slot 460. By rotating the hinge plate 421, the fixing plate 410 on the rectangular plate 422 and the fixing plate 410 on the T-shaped plate 40 are located on the same horizontal plane.

Afterwards, the staff rotates the hinge plate 421, and the hinge plate 421 rotates to a horizontal state. The rectangular plate 422 drives the corresponding fixed plate 410 to rotate synchronously, and finally the two wire clamping assemblies 41 are distributed left and right. In the above process, the hinge plate 421 drives the support column 521 thereon to move synchronously. Before the support column 521 drives the support block 522 to pass through the support groove 520, the support column 521 is rotated so that the support block 522 can pass through the support groove 520. At the same time, the volute spring 523 is deformed. After the support block 522 passes through the support groove 520, the volute spring 523 is deformed and reset so that the two support blocks 522 are restored to the front and back distribution state. Therefore, the support block 522 and the L-shaped plate 52 cooperate to keep the hinge plate 421 horizontal (see Figure 7) for the subsequent wiring harness plug-in. Finally, the right end of the wiring harness is cut according to the required plug-in length on the right side of the wiring harness.

It should be noted that the distance from the support block 522 to the hinged plate 421 is the same as the vertical distance from the L-shaped plate 52 to the upper end surface of the movable plate 420; the avoidance groove 524 is opened to prevent the L-shaped frame 2 and the L-shaped plate 52 from being stuck with each other and unable to move during the subsequent rectangular plate 422 driving the corresponding wiring harness to perform right-side plug-in.

As shown in Figures 2, 3 and 4, the guide unit 44 also includes a sliding column 441. The sliding columns 441 are fixedly arranged at both the front and rear ends of the fixed plate 410. A rectangular block 442 is fixedly sleeved on the sliding column 441. The lower end surface of the rectangular block 442 corresponding to the T-shaped plate 40 and the left end surface of the other rectangular block 442 are fixedly connected to the corresponding guide column 440, and the axis of the guide column 440 extends along the width direction of the corresponding fixed plate 410. A locking column 443 with a diameter the same as the inner diameter of the mounting hole is fixedly sleeved on the guide column 440.

As shown in Figures 2, 3 and 4, the guiding unit 44 also includes a limiting arc plate 444. The left end face of the fixed plate 410 corresponding to the T-shaped plate 40 and the upper end face of the other fixed plate 410 are fixedly provided with a plurality of limiting arc plates 444 equidistantly distributed front to back, and the opening of the limiting arc plate 444 faces the corresponding mounting plate 411. The inner arc surface of the limiting arc plate 444 on the fixed plate 410 corresponding to the rectangular plate 422 is fixedly provided with a plurality of circumferentially distributed limiting strips 445, and the limiting strips 445 gradually approach the axis of the limiting arc plate 444 from bottom to top, and the limiting arc plate 444 and the limiting strips 445 are both made of rubber.

During operation, after the two wire clamping assemblies 41 are distributed left and right and kept horizontal, the T-shaped plate 40 is manually moved so that the two wire clamping assemblies 41 drive the wiring harness to move left synchronously. During the left movement, the T-shaped plate 40 drives the guide column 440 to move left and insert it into the mounting hole on the terminal block through the corresponding fixed plate 410. As the left movement continues, the positioning column 443 on the guide column 440 is inserted into the mounting hole. Then the T-shaped plate 40 is continuously moved so that the left end of the wiring harness is inserted into the plug-in hole on the terminal block. The staff locks the wiring harness by tightening the screws on the upper end face of the terminal block. Then the staff pushes the left L-shaped frame 2 and the T-shaped plate 40 at the same time, so the T-shaped plate 40 drives the rectangular plate 422 and the wire clamping assembly 41 thereon to repeat the above operation, inserts the right end of the wiring harness into the right terminal block, and manually tightens the screws to complete the overall wiring harness plug-in operation, and finally manually removes the terminal block and the wiring harness.

It should be noted that when the wiring harness is placed between the fixed plate 410 and the mounting plate 411 in the wire clamping assembly 41 corresponding to the T-shaped plate 40, the staff will pass each wiring harness through the limiting arc plate 444 on the fixed plate 410 in turn, and limit and guide the left end portion of the wiring harness through the limiting arc plate 444 to facilitate the insertion of the wiring harness into the terminal row on the left, and then lock and fix this part of the wiring harness through the wire pressing group in the wire clamping assembly 41. After completing the above operations, the wiring harness is horizontal in the left section and vertical in the right section. When assembling another wire clamping assembly 41, the staff will hold the fixed plate 410 in the wire clamping assembly 41 and make the opening of the limiting arc plate 444 on the fixed plate 410 align with the right side portion of the wiring harness on the T-shaped plate 40. The fixing plate 410 is pressed down so that the multiple wiring harnesses are all inserted into the limiting arc plate 444 on the fixing plate 410, and then the mounting plate 411 in the wire clamping assembly 41 is installed; secondly, in the process of plugging the plug-in column 46 with the rectangular plate 422 and adjusting the hinged plate 421, the friction between the limiting strip 445 and the wiring harness is used to make the limiting arc plate 444 on the fixing plate 410 corresponding to the plug-in column straighten the wiring harness, so as to avoid the problem that the wiring harness is too long and affects the use of the subsequent terminal row and causes waste. Secondly, the limiting strip 445 arranged circumferentially presses the wiring harness to limit and fix the wiring harness, and at the same time helps to keep the wiring harness between the two fixing plates 410 in a straight state, which is beneficial to improve the efficiency and quality of wiring harness plug-in.
