Description

Technical Field

[0001] This utility model belongs to the technical field of terminal blocks and their accessories, and in particular relates to a terminal block with a dustproof structure. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. Terminal blocks include types such as plug-in type, spring type, barrier type, and rail type. In particular, plug-in type is the most widely used due to its extremely simple structure and operation. Currently, terminal blocks mainly consist of three parts: an insulating shell, contacts, and a fixing structure. The contacts are embedded in multiple wire holes in the insulating shell, while the fixing structure is installed at the top of the wire holes and is positioned opposite to the contacts. Thus, the fixing structure fixes the wires inserted into the wire holes to the contacts.

[0003] Patent application CN223007042U discloses a terminal block comprising a housing, a conductive block, a mounting block, and a dust cover. The housing is open, and the conductive block is mounted on the housing. The mounting block is connected to the conductive block, and the dust cover is connected to the housing and covers the conductive block. This application improves the dustproof performance of the terminal block.

[0004] The aforementioned terminal block has multiple conductive blocks inside its housing, and a dust cover is installed on the top of the conductive blocks and on the outer wall of the housing. However, there are large gaps between the front and rear sides of the dust cover and the housing, allowing dust to completely enter the housing through these gaps, thus essentially negating the dustproof effect of the dust cover. Furthermore, the conductive blocks have input and output terminals at their upper and lower ends, respectively, both composed of threaded fasteners and locking elements made of contact pieces. The dust cover also obstructs the wires, hindering wiring operations. Therefore, we provide a terminal block with a dustproof structure to solve the aforementioned problems. Utility Model Content

The end of the first cylinder is fixed to the side wall of the slot, and the end of the second cylinder is fixed to the side wall of the slider.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a dustproof component. The upper end and front sidewall of the insulating shell are provided with outer grooves. A dustproof component is installed within these grooves. The dustproof component includes a rotating plate covering the outer groove, with a rotating rod inserted into the end of the rotating plate. Return springs are installed at both ends of the rotating rod, which is connected to the inner wall of the outer groove via the return springs. A slot is provided at the outer end of the rotating plate, and a crescent-shaped inner plate is installed within the slot. A rubber rack is adhered to the inner ring sidewall of the inner plate. Sliding blocks are slidably mounted at both ends of the slot, and sliding plates are fixed to both sides of the sliding blocks. A second rubber rack is adhered to the outer wall of the sliding plate, and the sliding blocks are connected to the slot via an elastic rod. The racks of the first and second rubber racks are interlocked. When not in use, the torque of the return spring drives the rotating rod to rotate towards the insulating shell, ensuring that the rotating plate and the sliding plate at its end cover the outer groove of the insulating shell. When the rotating plate and the sliding plate are covered in the outer groove, first press down on the outer end of the sliding plate and... When the pressure is applied, the elastic rod is compressed, and the slider slides in the slot of the rotating plate. The sliding plate is temporarily pushed into the rotating plate. After the rotating plate is fully inserted into the outer groove, the pressure on the sliding plate is released. At this time, the elastic rod loses its pressure and pushes the sliding plate to move outward of the rotating plate until the outer end of the sliding plate is inserted into the outer groove of the outer groove. This creates a positioning dustproof component, which covers the outer groove of the insulating shell and prevents dust from the external environment from entering the insulating shell through the outer groove used for wiring. When wiring, the sliding plate is pressed so that its outer end is disengaged from the outer groove. Then the rotating plate is flipped open, and the wire used for wiring is inserted between rubber rack one and rubber rack two. At this time, the outer wall of the wire is pressed down by rubber rack one and rubber rack two, and the outer wall of the wire contacts rubber rack one and rubber rack two, which also seals the groove. Then the wire end is connected to the wiring component, and the rotating plate is closed.

[0017] 2. This utility model, through the setting of a wiring assembly, has multiple terminal bodies arranged at equal intervals inside the insulating shell. Wiring grooves are formed in the upper and front side walls of the terminal bodies, and wiring blocks are embedded in the inner walls of the wiring grooves. Mounting grooves are formed in the left and right side walls, and wiring components are installed in the mounting grooves. Each wiring component includes a mounting plate fixed in the mounting groove, a sliding pin inserted into the mounting plate, a pull ring fixed at the upper end of the sliding pin, and a pressure strip fixed at the lower end. The pressure strip is horizontally positioned directly above the wiring block. A connecting spring is also sleeved on the sliding pin, with the upper end connected to the bottom side wall of the mounting plate and the lower end connected to... The upper side wall of the pressure strip is connected. During use, after the stripped end of the wire passes through the dustproof component and enters the insulating shell, hold the pull ring and pull upward. At this time, the connecting spring is compressed, and the pressure strip moves upward as well. At this time, the distance between the pressure strip and the terminal block of the terminal body increases. Then, the stripped end is wrapped around the pressure strip. After the wrapping is completed, the pull ring is released. At this time, the connecting spring loses its pressure constraint and returns to its initial state, pushing the sliding plug and the pressure strip at its lower end to move downward. Finally, the pressure strip contacts the terminal block of the terminal body through the stripped wire wrapped around its outer wall, thus completing the wiring operation.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Please see Figure 1-3 This utility model is a terminal block with a dustproof structure, including an insulating shell 1 and a dustproof component 3. The dustproof component 3 can effectively prevent dust when the terminal block is not in use or when it is in use.

[0028] Specifically, the insulating housing 1 has a terminal slot 101 inside, and an outer slot 102 is provided on the upper end and the front side wall of the terminal slot 101. Mounting screws 2 are installed on both the left and right ends of the insulating housing 1. A dustproof component 3 is installed in the outer slot 102. The dustproof component 3 includes a rotating plate 301 installed in the outer slot 102. A rotating rod 302 is inserted into the end of the rotating plate 301, and a return spring 302a is installed at both ends of the rotating rod 302. The end of the rotating rod 302 is connected to the inner wall of the outer slot 102 through the return spring 302a.

[0029] Furthermore, a slot 301a is provided at the outer end of the rotating plate 301, and an inner plate 303 is installed in the slot 301a. The inner plate 303 is crescent-shaped, and a rubber toothed rack 303a is bonded to the inner ring sidewall of the inner plate 303. A sliding plate 304 is also slidably disposed in the slot 301a of the rotating plate 301. A rubber toothed rack 304a is bonded to the outer wall of the side of the sliding plate 304 facing the inner plate 303. Two pieces of rubber toothed rack 304a are fixed on the outer walls of both ends of the sliding plate 304. A slider 304b is provided and is slidably connected to a slot 301a. An elastic rod 305 is also installed on the slider 304b. The elastic rod 305 includes a first cylinder 305a and a second cylinder 305b slidably inserted into the end of the first cylinder 305a. A traction spring 305c is also provided inside the first cylinder 305a. The end of the first cylinder 305a is fixed to the side wall of the slot 301a, and the end of the second cylinder 305b is fixed to the side wall of the slider 304b.

[0030] The operation process of this embodiment is as follows: When not in use, the torque of the return spring 302a drives the rotating rod 302 to rotate towards the insulating shell 1, ensuring that the rotating plate 301 and the sliding plate 304 at its end cover the outer groove 102 of the insulating shell 1. When the rotating plate 301 and the sliding plate 304 cover the outer groove 102, first press the outer end of the sliding plate 304 and squeeze it. At this time, the elastic rod 305 is compressed, and the slider 304b slides in the slot 301a of the rotating plate 301. That is, the sliding plate 304 is temporarily pushed into the rotating plate 301. After the rotating plate 301 is completely inserted into the outer groove 102, release the hand pressing the sliding plate 304. At this time, the elastic rod 305 loses its pressure and pushes the sliding plate 304 to move outward from the rotating plate 301 until the sliding plate 304... The outer end of the wire is inserted into the outer groove of the outer slot 102 to form a positioning dustproof component 3, so that the dustproof component 3 covers the outer groove 102 of the insulating shell 1, which prevents dust in the external environment from entering the insulating shell 1 through the outer groove 102 used for wiring. When wiring, the sliding plate 304 is pressed to make its outer end disengage from the outer groove 102, and then the rotating plate 301 is flipped outward, and the wire used for wiring is inserted between the rubber toothed rack 1 303a and the rubber toothed rack 2 304a. At this time, the outer wall of the wire is pressed down by the rubber toothed rack 1 303a and the rubber toothed rack 2 304a and bends elastically. The outer wall of the wire contacts the rubber toothed rack 1 303a and the rubber toothed rack 2 304a, which also seals the groove. Then the wire end is connected to the wiring component 3, and the rotating plate 301 is closed.

[0031] Example 2

[0032] Please see Figure 4Based on embodiment 1, a wiring assembly 4 is also provided, which enables a quick and stable connection of the wires.

[0033] Specifically, the wiring assembly 4 includes a fixing frame 402 disposed in the terminal slot 101, and a terminal body 401 is installed in the fixing frame 402. Wiring slots 401a are provided in the upper side wall and the front side wall of the terminal body 401, and a wiring block 401b is embedded in the inner wall at the center of the wiring slot 401a. Mounting slots 401c are also provided on the inner walls on the left and right sides of the wiring slot 401a.

[0034] Furthermore, a connector 403 is installed in the mounting slot 401c. The connector 403 includes a mounting plate 403a fixed in the mounting slot 401c, and a sliding post 403b is slidably inserted into the mounting plate 403a. A pull ring 403d and a pressure strip 403e are fixedly installed at the upper and lower ends of the sliding post 403b, respectively. A connecting spring 403c is also sleeved on the sliding post 403b. The upper end of the connecting spring 403c is connected to the bottom side wall of the mounting plate 403a, and the lower end is connected to the upper side wall of the pressure strip 403e. The pressure strip 403e is also horizontally positioned above the connector 401b.

[0035] The operation process of this embodiment is as follows: When in use, after the end of the wire with the stripped insulation passes through the dustproof component 3 and enters the insulating shell 1, the pull ring 403d is held and pulled upward. At this time, the connecting spring 403c is compressed, and the pressure bar 403e also moves upward. At this time, the distance between the pressure bar 403e and the terminal block 401b of the terminal body 401 increases. Then, the stripped end is wrapped around the pressure bar 403e. After the wrapping is completed, the pull ring 403d is released. At this time, the connecting spring 403c loses its pressure constraint and returns to its initial state, pushing the sliding plug 403b and the pressure bar 403e at its lower end to move downward. Finally, the pressure bar 403e contacts the terminal block 401b of the terminal body 401 through the stripped wire wrapped around its outer wall, thereby completing the wiring operation.
