Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal block technology, and specifically to a terminal block with a connector designed to prevent breakage. Background Technology
[0002] Terminal blocks are critical components in electrical connections, used to safely and reliably connect wires and prevent loosening, short circuits, or breakage.
[0003] Currently, when the terminal block clamps and fixes the wire core, the contact area between the terminal block and the wire core is not comprehensive enough. During the clamping process, the wire core cannot be fully wrapped. The direct pressing method will cause the wire core to be flattened. If the clamping force is too large, the wire core is easy to be crushed and broken. In addition, it lacks a tensile resistance function, and external tension can easily cause the wire core to break. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a connector that prevents breakage. With replaceable clamping plates, it can adapt to wire cores of different diameters, thereby fully wrapping the wire core, dispersing stress, and reducing the probability of breakage, thus solving the problems mentioned in the background art.
[0005] This utility model is achieved through the following technical solution: a connector anti-breakage terminal block, including a lower clamping seat and an upper clamping seat, the lower clamping seat and the upper clamping seat are arranged parallel to each other, and clamping grooves are provided on the opposite surfaces of the lower clamping seat and the upper clamping seat. Clamping plates are provided at both ends of the clamping grooves, and clamping channels are formed between the clamping plates. Wiring grooves are installed at both ends of the lower clamping seat, and the middle of the wiring grooves is bent to form a buffer part. Spring pieces are installed at both ends of the upper clamping seat, and the other end of the spring pieces is bent to form a downward pressure post, which extends into the buffer part.
[0006] As a preferred technical solution, the clamping plates are all arranged in an arc shape, and the outer ring surface of the clamping plates all protrudes to form a limiting part. The inner wall surface of the clamping groove is provided with a limiting groove at the position opposite to the limiting part, and the limiting part is inserted into the limiting groove.
[0007] As a preferred technical solution, both the lower clamping seat and the upper clamping seat are provided with through holes at the middle, and bolts are inserted into the corresponding through holes. One end of the bolt is threaded with a nut that presses the lower clamping seat and the upper clamping seat together.
[0008] As a preferred technical solution, multiple hinges are installed on one side of the upper clamping seat and the lower clamping seat. Multiple positioning parts are protruded on the end face of the upper clamping seat facing the lower clamping seat, and multiple positioning grooves are provided on the end face of the lower clamping seat facing the upper clamping seat. The positioning parts are all inserted into the corresponding positioning grooves.
[0009] As a preferred technical solution, the clamping plates are all made of brass.
[0010] As a preferred technical solution, the vertical cross-section of the wiring trough is designed with a "U" shape.
[0011] As a preferred technical solution, the spring is a metal elastic sheet.
[0012] The beneficial effects of this utility model are: the utility model has a simple structure, and the replaceable clamping plate can adapt to wire cores of different diameters, so that the clamping channel formed by the clamping plate matches the diameter of the wire core, which can fully wrap the wire core, disperse stress, and reduce the probability of breakage. The wire can bend into the buffer part and be pressed by the pressure column. When it is pulled by the outside, it can stretch the wire, and the wire can rise and squeeze the pressure column and the spring. The elasticity of the spring can play a buffering role and reduce the probability of being pulled off. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a connector anti-breakage terminal block, comprising a lower clamping seat 1 and an upper clamping seat 2. The lower clamping seat 1 and the upper clamping seat 2 are arranged parallel to each other, one above the other, and clamping grooves are provided on the opposite surfaces of the lower clamping seat 1 and the upper clamping seat 2. Clamping plates 7 are provided at both ends of the clamping grooves, and clamping channels are formed between the clamping plates 7. Wiring grooves 3 are installed at both ends of the lower clamping seat 1, and the middle of the wiring grooves 3 is bent to form a buffer part 4. Spring pieces 5 are installed at both ends of the upper clamping seat 2, and the other end of the spring pieces 5 is bent to form a downward pressing post 6, which extends into the buffer part 4.
[0023] In this embodiment, the clamping plates 7 are all arranged in an arc shape, and the outer ring surface of the clamping plates 7 is protruding to form a limiting part 12. The inner wall surface of the clamping groove is provided with a limiting groove 10 opposite to the limiting part 12, and the limiting part 12 is inserted into the limiting groove 10.
[0024] The clamping plate is positioned by the limiting part and the limiting groove, which prevents the clamping plate from moving laterally. After the clamping plates come together, they can be pressed together, which further ensures the stability of the clamping plate.
[0025] In this embodiment, a through hole is vertically provided at the middle of both the lower clamping seat 1 and the upper clamping seat 2. A bolt 8 is inserted into the opposite through hole, and a nut 9 is threadedly connected to one end of the bolt 8 to press the lower clamping seat 1 and the upper clamping seat 2 together.
[0026] In this embodiment, multiple hinges are installed on one side of the upper clamping seat 2 and the lower clamping seat 1. Multiple positioning parts are formed on the end face of the upper clamping seat 2 facing the lower clamping seat 1. Multiple positioning grooves 11 are provided on the end face of the lower clamping seat 1 facing the upper clamping seat 2. The positioning parts are all inserted into the corresponding positioning grooves 11.
[0027] The upper and lower clamping seats can be connected together by a hinge, which avoids the separation of the two after opening; the side of the positioning part is provided with a guide part, so that the positioning part can be smoothly inserted into the positioning groove.
[0028] In this embodiment, the clamping plates 7 are all made of brass. The upper clamping seat and the lower clamping seat are also made of brass, which enables the clamping plates to have good conductivity with the lower clamping seat and the upper clamping seat, and also gives the clamping plates a certain degree of elasticity, which can better reduce the occurrence of wire core breakage.
[0029] In this embodiment, the vertical cross-section of the wiring trough 3 is arranged in a "U" shape. After the wire enters the wiring trough, it can be blocked by the two sides of the wiring trough, thus preventing it from falling out of the wiring trough.
[0030] In this embodiment, the spring 5 is a metal elastic sheet, which gives the spring good elasticity and can better protect the wire and the core.
[0031] As attached Figure 4 As shown, during installation, unscrew the nut and pull out the bolt. After the bolt is removed, the upper clamp can be opened, and the clamping channel is also open. The wire core can be put into the clamping plate, and the wire can be bent into the wiring channel. The wire bends into the buffer part at the point where it is aligned with the buffer part. After the upper clamp covers the lower clamp with the hinge as the center, the positioning part can be inserted into the positioning groove, and the clamping plate can wrap around the outside of the wire core. The movement of the upper clamp drives the spring and the lower pressure post. The lower pressure post can fully press the bent part of the wire into the buffer part, and the bolt can pass through the through hole and lock the upper clamp and the lower clamp together with the nut. This also allows the clamping plate to press the wire core tightly and fix it.
[0032] When subjected to external pulling, the tension will act on the wire, straightening it. During the straightening process, the wire can squeeze the pressure post and the spring. The elasticity of the spring can play a buffering role, reducing the sudden tension and the probability of the wire core breaking.
[0033] The clamping plate is positioned in the clamping groove by the limiting part. After the upper clamping seat and the lower clamping seat are opened, the clamping plate can be taken out and clamping plates of different thicknesses can be installed. This allows the inner diameter of the clamping channel to be changed to accommodate wire cores of different diameters, so that the clamping plate can make full contact with the wire core, disperse stress, and reduce the probability of breakage.
[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
