Description

Technical Field

[0001] This utility model relates to the field of distribution box terminal technology, specifically to a wire harness terminal plug-in structure for distribution cabinets. Background Technology

[0002] Terminals are components that connect a battery to an external conductor. In electrical engineering, terminals often refer to wiring terminals, also called wire terminals. Types include single-hole, double-hole, plug-in, and hook types. Materials include silver-plated copper, zinc-plated copper, copper, aluminum, and iron. Their primary function is to transmit electrical signals or conduct electricity.

[0003] Chinese utility model patent application number 202322512002.6 provides a terminal block structure for high and low voltage distribution cabinets. The rotating structure can drive the threaded rod to rotate. Each cylindrical block drives two threaded sleeves to move in opposite directions. The two threaded sleeves drive the first insertion rod and the second insertion rod to move in opposite directions from the through hole through the first moving rod and the second moving rod, thereby removing the terminal block body from the mounting plate and taking it out of the distribution cabinet body for easy maintenance.

[0004] However, during the use of the above equipment, it was found that when a single terminal malfunctions, the entire terminal block needs to be disassembled for repair. This process requires disconnecting all the wires connecting the terminals, which takes a lot of time. After the fault is repaired, reinstalling the entire terminal block also takes a lot of time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wire harness terminal plug-in structure for power distribution cabinets, which solves the problem mentioned in the background technology that when a single terminal fails, the entire terminal block needs to be disassembled for repair, and a lot of time is spent in the process of disassembling and installing wires.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire harness terminal plug-in structure for a power distribution cabinet, comprising a cabinet box, an installation frame installed inside the cabinet box, an installation plate provided on one side of the installation frame, an installation groove provided on the installation plate, the installation groove being adapted to an installation block, the installation block being fixed to the bottom of a connection terminal, a limiting block connected to the bottom of the installation block, the limiting block being inverted T-shaped, a drive assembly provided inside the installation plate, the drive assembly including a rotating shaft, limiting rods fixedly installed on both sides of the top of the rotating shaft, the limiting rods being L-shaped, the rotating shaft rotating in a rotating groove, the rotating groove being located at the bottom of the installation groove.

[0007] Preferably, the drive assembly includes a drive groove, which is disposed at the bottom of the rotating groove, and a worm gear is rotatably mounted on one side inside the drive groove.

[0008] Preferably, a handle is fixedly installed at one end of the worm gear, and a slot is opened on one side of the handle. The slot on the handle is located on the outside of the mounting plate.

[0009] Preferably, a worm wheel is meshed with one side of the worm, the worm wheel is rotatably disposed in the drive groove, and the top of the worm wheel is fixedly connected to the rotating shaft.

[0010] Preferably, the rotating shaft is adapted to the rotating groove, and the limiting rods on both sides of the top of the rotating shaft are arranged in a rotationally symmetrical manner.

[0011] Preferably, the limiting block has two layers, upper and lower, and the distance between the limiting rods on both sides is the same as the width of the limiting block. The upper layer of the limiting block is cylindrical, and the distance between the bottom of the limiting rod beam and the rotating shaft is the same as the height of the lower layer of the limiting block.

[0012] This utility model provides a wire harness terminal plug-in structure for power distribution cabinets. It has the following advantages:

[0013] (1) This utility model uses the limit rod in the drive assembly to limit the limit block at the bottom of the connecting terminal to complete the installation. When a single terminal fails, the drive assembly can be operated to release the limit rod from the limit block of the faulty terminal, and the faulty terminal can be quickly disassembled, which greatly shortens the maintenance time.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-5 A wiring harness terminal plug-in structure for a power distribution cabinet includes a cabinet box 1. A mounting frame 2 is installed inside the cabinet box 1. A mounting plate 21 is provided on one side of the mounting frame 2. A mounting groove 22 is provided on the mounting plate 21. The mounting groove 22 is adapted to the mounting block 31. The mounting block 31 is fixed to the bottom of the connecting terminal 3. A limit block 32 is connected to the bottom of the mounting block 31. The limit block 32 is inverted T-shaped. A drive assembly 4 is provided inside the mounting plate 21. The drive assembly 4 includes a rotating shaft 44. Limit rods 45 are fixedly installed on both sides of the top of the rotating shaft 44. The limit rods 45 are L-shaped. The rotating shaft 44 rotates in a rotating groove 46. The rotating groove 46 is opened at the bottom of the mounting groove 22.

[0025] The rotating shaft 44 is adapted to the rotating groove 46, and the limiting rods 45 on both sides of the top of the rotating shaft 44 are arranged in a rotationally symmetrical manner.

[0026] The limiting block 32 has two layers, and the distance between the limiting rods 45 on both sides is the same as the width of the limiting block 32. The upper layer of the limiting block 32 is cylindrical, and the distance between the bottom of the limiting rod 45 crossbeam and the rotating shaft 44 is the same as the height of the lower layer of the limiting block 32.

[0027] Specifically, when installing the connecting terminal 3, align the mounting block 31 at the bottom of the connecting terminal 3 with the mounting groove 22 on the mounting plate 21. Since the mounting groove 22 and the mounting block 31 are compatible, this ensures that the connecting terminal 3 can enter the mounting plate 21 in the correct direction when inserted. At the same time, during the insertion process, the inverted T-shaped limiting block 32 at the bottom of the mounting block 31 also enters the mounting groove 22. At this time, since the rotating shaft 44 in the drive assembly 4 is in the initial position (not rotated), the limiting rod 45 will not obstruct the limiting block 32. When the connecting terminal 3 is fully inserted into the mounting groove 22, the upper layer (cylindrical part) of the limiting block 32 is located between the crossbeams of the limiting rods 45 on both sides, controlling the rotating shaft 44 to rotate. When the rotating shaft 44 rotates, it drives the limiting rods 45 on both sides of the top to rotate synchronously. Since the distance between the bottom of the limit rod 45 crossbeam and the rotating shaft 44 is the same as the height of the lower layer of the limit block 32, when the limit rod 45 rotates at a certain angle, the crossbeam of the limit rod 45 will be stuck above the lower layer of the limit block 32 and perpendicular to the limit block 32, thereby fixing the limit block 32 and thus realizing the fixed installation of the connecting terminal 3.

[0028] When it is necessary to disassemble the connecting terminal 3, the reverse rotation of the rotating shaft 44 causes the limiting rod 45 to rotate in the opposite direction, causing the crossbeam of the limiting rod 45 to disengage from the upper part of the lower layer of the limiting block 32, thus releasing the restriction on the limiting block 32. Since the limiting block 32 is no longer fixed by the limiting rod 45, the connecting terminal 3 can be pulled vertically upward out of the mounting slot 22. During the pulling process, the mounting block 31 and the limiting block 32 also move out of the mounting slot 22, thereby completing the disassembly of the connecting terminal 3.

[0029] Each connection terminal 3 can be individually fixedly mounted on the mounting plate 21 via the drive assembly 4. If a single connection terminal 3 malfunctions, simply operate the limit rod 45 via the drive assembly 4 to release the restriction on the limit block 32 of the malfunctioning terminal, and the malfunctioning terminal can be directly pulled out. The entire process involves few steps and is straightforward, requiring no operation on other normal terminals, thus saving time and avoiding unnecessary waste.

[0030] Example 2:

[0031] To ensure the stability of the connection terminal 3 installation, please refer to [link / reference]. Figures 1-5 Based on embodiment 1, the drive assembly 4 includes a drive groove 47, which is located at the bottom of the rotating groove 46, and a worm gear 42 is rotatably mounted on one side inside the drive groove 47.

[0032] A handle 41 is fixedly installed at one end of the worm gear 42. A slot is opened on one side of the handle 41, and the slot on the handle 41 is located on the outside of the mounting plate 21.

[0033] A worm gear 43 is meshed with one side of the worm 42. The worm gear 43 is rotatably disposed in the drive groove 47, and the top of the worm gear 43 is fixedly connected to the rotating shaft 44.

[0034] Specifically, when it is necessary to drive the rotating shaft 44 to rotate, the operator inserts a tool into the slot on the handle 41 and uses the tool to control the rotation of the handle 41. Since one end of the worm 42 is fixedly connected to the handle 41, the rotational motion of the handle 41 is directly transmitted to the worm 42, causing the worm 42 to start rotating at the rotation position on one side inside the drive groove 47. As the worm 42 rotates, because the worm 42 and the worm wheel 43 are meshed, according to the transmission principle of the worm wheel 43 and worm 42, the worm 42 will drive the worm wheel 43 to rotate in the drive groove 47. Since the top of the worm wheel 43 is fixedly connected to the rotating shaft 44, when the worm wheel 43 rotates, the rotational motion of its top is directly transmitted to the rotating shaft 44, thereby realizing the rotation of the rotating shaft 44, which in turn facilitates the rotation of the limit rod 45.

[0035] Due to the self-locking characteristics of the worm gear 42 and worm 43, even if there is vibration or external interference during the movement of the equipment, the worm gear 43 can be prevented from driving the worm 42 in the opposite direction, thereby avoiding the limit rod 45 from accidentally loosening its restriction on the limit block 32 and ensuring the stability of the installation state of the connection terminal 3.

[0036] Working Principle: When using the equipment, first align the mounting block 31 at the bottom of the connecting terminal 3 with the mounting groove 22 on the mounting plate 21. This alignment guides the connecting terminal 3 into the mounting plate 21 in the correct direction. Simultaneously, the inverted T-shaped limiting block 32 at the bottom of the mounting block 31 enters the mounting groove 22 along with the mounting block 31. At this point, the rotating shaft 44 of the drive assembly 4 is in its initial position, and the limiting rod 45 does not obstruct the limiting block 32. After the connecting terminal 3 is fully inserted into the mounting groove 22, the operator uses a tool to insert into the slot of the rotating handle 41 and rotates the handle 41. The rotating handle 41 drives the worm gear 42, which is fixed to it, to rotate within the drive groove 47. The rotation of the worm gear 42 drives the meshing worm wheel 43 to rotate within the drive groove 47. Since the top of the worm wheel 43 is fixedly connected to the rotating shaft 44, the rotation of the worm wheel 43 causes the rotating shaft 44 to rotate. The rotating shaft 44 then drives the rotationally symmetrical limiting rods 45 on both sides to rotate synchronously. Since the distance from the bottom of the limit rod 45 crossbeam to the rotating shaft 44 is the same as the height of the lower layer of the limit block 32, after the limit rod 45 rotates at a certain angle, its crossbeam is stuck above the lower layer of the limit block 32, fixing the limit block 32 and completing the fixed installation of the connecting terminal 3.

[0037] When it is necessary to disassemble the connecting terminal 3, the operator uses a tool to rotate the handle 41 in the opposite direction. The handle 41 drives the worm gear 42 to rotate in the opposite direction, and the worm gear 42 drives the worm wheel 43 to rotate in the opposite direction, which in turn causes the rotating shaft 44 to drive the limit rod 45 to rotate in the opposite direction. The limit rod 45 crossbeam disengages from the lower layer above the limit block 32, releasing the restriction on the limit block 32.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
