Description

Technical Field

[0001] The utility model relates to the field of wiring terminal blocks, in particular to an improved wiring terminal block. Background Art

[0002] Terminal block refers to a solid device composed of an insulating base and one or more live parts. Each conductive part can be used as a connection point for two or more conductors (wires), and also as a tool for connecting or disconnecting conductors (wires) individually. When connecting a wire to a terminal, the insulation of one end of the wire is generally removed, and the conductive wire cluster of the wire is placed in the terminal. By turning the bolt to tighten the conductive wire cluster, the connection between the conductor and the terminal block is completed.

[0003] The existing terminal blocks and conductors need to be regularly inspected and maintained, so the staff need to reciprocately disassemble and assemble the conductors in a short period of time. Since the threaded structure between the two is prone to loosening after multiple disassembly and assembly, it will affect the stability of subsequent conductor connections. It is very easy to have poor contact for a long time, reducing the overall service life of the device.

[0004] In summary, the threaded structure between the two of the above structure is prone to loosening after multiple disassembly and assembly during use, which will affect the stability of subsequent conductor connections, and it is very easy to cause poor contact for a long time, reducing the overall service life of the device. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an improved terminal block to solve the technical problem that the threaded structure between the two is prone to loosening after multiple disassembly and assembly, thereby affecting the stability of subsequent conductor connections, and is prone to poor contact for a long time, thereby reducing the overall service life of the device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an improved terminal block, comprising a shell, one side of the shell is provided with an array of sockets, the top of the shell penetrates into the shell and a bolt assembly is rotatably arranged, and guide pillars are elastically and symmetrically arranged in the shell, one side of the guide pillar and the bottom end of the bolt assembly are both arranged in an arc shape, one side of the guide pillar is connected to a U-shaped rod, and a pressure foot is installed at the other end of the U-shaped rod.

[0007] By adopting the above technical solution, the guide posts on both sides will be squeezed by the bolt assembly during the sliding process, so that the guide posts drive the presser foot to slide to both sides through the U-shaped rod. At this time, the staff can insert the conductor through the socket, and then reverse the bolt assembly to make it slide upward. In this process, the guide post is driven to reset and slide under the action of the reset spring, so that the presser foot can limit the inserted conductor. In this process, the bolt assembly plays a role of up and down adjustment, and shaking during long-term use will not affect the limiting of the conductor.

[0008] The utility model is further configured that the side walls of the guide pillars are all provided with connecting rods, the other ends of the connecting rods are installed with sealing plates, and the inner side of the sealing plates is arranged in an arc shape.

[0009] By adopting the above technical solution, when the guide column slides to both sides, the sealing plate will be driven to move with it, thereby releasing the sealing work of the socket. During the subsequent resetting process of the guide column, the sealing plate will also slide with the resetting to seal the socket again, effectively preventing external dust and impurities from infecting the device through the socket, thereby increasing the overall service life of the device. At the same time, the arc-shaped setting of the sealing plate facilitates the support of the inserted conductor and improves the stability of the conductor in the shell.

[0010] The utility model is further configured that a threaded cylinder matched with the bolt assembly is arranged in the shell.

[0011] By adopting the above technical solution, the bolt assembly itself is prevented from violently sliding up and down due to vibration under the action of the threaded barrel, thereby improving the stability of the bolt assembly in the threaded barrel.

[0012] The utility model is further configured that a return spring is symmetrically arranged in the shell, and a guide column is connected to the other end of the return spring.

[0013] By adopting the above technical solution, when the bolt assembly slides downward, the guide posts on both sides will be driven to move. During this process, the reset spring itself will be in a compressed state. Then, when the bolt assembly resets and slides upward, the reset spring itself will release the limiting work, and the guide posts will be driven to move by the reset force of the reset spring.

[0014] The utility model is further configured such that the socket is configured in an opening shape.

[0015] By adopting the above technical solution, the open-shaped socket facilitates the guidance of the insertion of the conductor, and at the same time allows the dust accumulated at the inclined part of the socket to slide to one side, effectively preventing the accumulation of dust at the socket.

[0016] The utility model is further configured that the inner wall of the sealing plate is provided with a protective sleeve, and the protective sleeve itself is provided in a rough shape.

[0017] By adopting the above technical solution, the protective cover can prevent the sealing plate from directly contacting the outer wall of the conductor. The protective cover can protect the outer wall of the conductor and effectively prevent it from being worn. The rough setting increases the sliding friction between the protective cover and the conductor, preventing the conductor from reciprocating and extending at the socket.

[0018] The utility model is further configured that the outer wall of the shell is provided with an array of mounting holes.

[0019] By adopting the above technical solution, the setting of the installation holes makes it easier for subsequent staff to install the device in a designated area.

[0020] The utility model is further configured that the connection between the sealing plate and the shell is a sealing arrangement.

[0021] By adopting the above technical solution, the sealing arrangement effectively prevents external dust and impurities from penetrating into the shell through the gap between the sealing plate and the shell.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] 1. The utility model elastically arranges a guide post in the shell. When the staff rotates the bolt assembly through a tool to make it slide downward, since one side of the guide post and the bottom end of the bolt assembly are both arranged in an arc shape, the bolt assembly will squeeze the guide posts on both sides during the sliding process, so that the guide posts drive the presser foot to slide to both sides through the U-shaped rod. At this time, the staff can insert the conductor through the socket, and then reverse the bolt assembly to make it slide upward. In this process, the guide post is driven to reset and slide under the action of the reset spring, so that the presser foot can limit the inserted conductor. In this process, the bolt assembly plays a role of up and down adjustment, and the shaking during long-term use will not affect the limiting of the conductor.

[0024] 2. The utility model provides a connecting rod on one side of the guide column. When the guide column slides to both sides, the sealing plate will be driven to move with it, thereby releasing the sealing work of the socket. During the subsequent resetting of the guide column, the sealing plate will also slide with the resetting to seal the socket again, effectively preventing external dust and impurities from infecting the device through the socket, thereby increasing the overall service life of the device. At the same time, the sealing plate can also support the inserted conductor, improving the stability of the conductor in the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] Embodiment 1

[0033] An improved terminal block, such as Figure 1-Figure 4 As shown, it includes a shell 1, a socket 3, a limiting mechanism, a sliding mechanism and a sealing mechanism. An array of mounting holes is provided on the outer wall of the shell 1. The setting of the mounting holes facilitates subsequent staff to install the device in a designated area. Then the staff rotates the bolt assembly 2 on the top of the shell 1 with a handheld tool. At this time, the bolt assembly 2 itself slides toward the bottom of the shell 1, and a threaded barrel 5 matched with the bolt assembly 2 is provided in the shell 1. The bolt assembly 2 itself is prevented from violently sliding up and down due to vibration under the action of the threaded barrel 5, thereby improving the stability of the bolt assembly 2 in the threaded barrel 5. Since guide pillars 6 are elastically and symmetrically provided in the shell 1, and the guide pillars 6 are One side and the bottom end of the bolt assembly 2 are both arranged in an arc shape, a U-shaped rod 10 is connected to one side of the guide column 6, and a presser foot 7 is installed at the other end of the U-shaped rod 10. Therefore, the bolt assembly 2 will squeeze the guide columns 6 on both sides during the sliding process, so that the guide columns 6 drive the presser foot 7 to slide to both sides through the U-shaped rod 10. At this time, the staff can insert the conductor through the socket 3, and then reverse the bolt assembly 2 to make it slide upward. In this process, the guide column 6 is driven to reset and slide under the action of the elastic component, so that the presser foot 7 can limit the inserted conductor. In this process, the bolt assembly 2 plays a role of up and down adjustment, and the shaking caused by long-term use will not affect the limiting of the conductor.

[0034] See also Figure 2A return spring 8 is symmetrically arranged in the shell 1, and the other end of the return spring 8 is connected to a guide column 6. When the bolt assembly 2 slides downward, the guide columns 6 on both sides will be driven to move. During this process, the return spring 8 itself will be in a compressed state. Then, when the bolt assembly 2 returns to slide upward, the return spring 8 itself will release the limit work, and the guide column 6 will be driven to move by the return force of the return spring 8.

[0035] Embodiment 2

[0036] like Figure 3 An improved terminal block is shown, and its overall structure is similar to that of the first embodiment, wherein the side walls of the guide column 6 are all provided with connecting rods 9, and a sealing plate 4 is installed at the other end of the connecting rod 9, and the inner side of the sealing plate 4 is arranged in an arc shape. When the guide column 6 slides to both sides, the sealing plate 4 will be driven to move with it, thereby releasing the sealing work of the socket 3. During the subsequent resetting process of the guide column 6, the sealing plate 4 will also follow the resetting and slide, and seal the socket 3 again, effectively preventing external dust and impurities from infecting the device through the socket 3, thereby improving the overall service life of the device. At the same time, the arc-shaped setting of the sealing plate 4 facilitates the support of the inserted conductor and improves the stability of the conductor in the shell 1.

[0037] See also Figure 3 The inner wall of the sealing plate 4 is provided with a protective cover, and the protective cover itself is rough. The protective cover can prevent the sealing plate 4 from directly contacting the outer wall of the conductor. The protective cover can protect the outer wall of the conductor and effectively prevent it from being worn. The rough setting increases the sliding friction between the protective cover and the conductor, preventing the conductor from reciprocating and telescoping at the socket.

[0038] The working principle of the utility model is as follows: when in use, the staff rotates the bolt assembly 2 through a tool, and the bolt assembly 2 slides downward. Since the contact surfaces of the bolt assembly 2 and the guide column 6 are both arranged in an arc shape, the guide column 6 will be driven to slide to both sides during the downward sliding process of the bolt assembly 2. During this process, the presser foot 7 will also slide. At this time, the staff can insert the conductor through the socket 3 at one end of the shell 1, and then reverse the bolt assembly 2 through a tool, so that the bolt assembly 2 slides upward and resets. At this time, the guide column 6 is driven to reset following the action of the reset spring 8, thereby driving the presser foot 7 to limit the inserted conductor. During this process, the shaking of the bolt assembly 2 itself will not affect the overall stability of the device, thereby further improving the overall service life.

[0039] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
