Description

Technical Field

[0001] The utility model belongs to the technical field of wiring terminals, and in particular relates to a wire wiring terminal. Background Art

[0002] Terminal blocks are a device used for electrical connections, mainly used to achieve safe and reliable connections between wires. They are widely used in electrical equipment, circuit boards, control cabinets and other fields.

[0003] The connection part of the existing terminal block is usually in a round tube structure. The round tube is flattened to clamp the wire for fixation. Usually, the round tube is pressed to cause uneven force. Usually, only a small section contacts to clamp the wire, and the connection is not reliable. After pressing evenly, the wire is still only subjected to the friction force of the round tube. In the case that the wire is relatively smooth, it is still easy to cause the wire to partially fall off or even completely fall off when pulled. Summary of the invention

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a wire connection terminal.

[0005] The technical solution of the utility model is as follows: a wire connection terminal, comprising a joint part and a connection part integrally connected to the joint part, the joint part is provided with a mounting hole, the connection part is integrally provided with a plurality of upper and lower bow parts that are arched outward and can be pressed to deform, the arching directions of the upper and lower bow parts are opposite, the connection part comprises a gap for passing the wire with the arched parts of each of the upper and lower bow parts facing inward, the upper and lower bow parts are sequentially arranged on the connection part along the wire access direction, the adjacent upper bow parts are arranged at intervals, and the adjacent lower bow parts are arranged at intervals.

[0006] By adopting the above technical solution, a plurality of upper and lower arched portions arched in opposite directions are provided, and the upper and lower arched portions are pressed inwardly, each of the upper and lower arched portions can not only contact with the wire to provide friction resistance, but further, the pressure acts on the wire to make the wire tilt in the direction of the corresponding notch, and there are adjacent upper and lower arched portions, and the inclination in opposite directions causes the wire to form a curved section, and the curved section of the wire contacts and is clamped by the side walls of the upper and lower arched portions, and is subjected to a corresponding supporting force opposite to the wire escape direction, thereby greatly increasing the connection stability of the wire, and the overall structure is simple, and at the same time, adjacent upper and lower arched portions are spaced apart, which reduces the use of materials and saves costs.

[0007] A further configuration of the utility model is that each of the upper arched portion and the lower arched portion is alternately arranged on the wiring portion.

[0008] With the above further settings, the alternately arranged upper bow portion and lower bow portion increase the number of inclined bending segments of the wire, increasing the contact area between the inclined bending part of the wire and the side walls of the upper bow portion and the lower bow portion, and increasing the number of clamping segments, greatly increasing the maximum supporting force of the side walls of the upper bow portion and the lower bow portion on the wire, and making the connection more stable.

[0009] A further setting of the present utility model: The notch extends towards the wire extraction direction to one end of the wiring portion to form an opening.

[0010] With the above further setting, the notch extends to the outside, causing the wiring portion to form an opening, and the opening facilitates the insertion of the wire into the notch without having to bypass the bottom end of the wiring portion, making the wire fixing convenient and fast.

[0011] A further setting of the present utility model: The notch is integrally in a rectangular through-hole structure.

[0014] With the above further setting, the insulating layer can ensure the safety of electrical connections, can block current conduction, and avoid accidental contact between wires or between wires and other conductive components, thereby ensuring the normal operation of the entire electrical system.

[0015] A further setting of the present utility model: The material of the insulating layer includes insulating materials that are heat-resistant and corrosion-resistant.

[0016] With the above further setting, the wiring terminal has the functions of flame retardancy and corrosion prevention, isolates external moisture, reduces conductor oxidation, increases the service life of the terminal, and the flame retardant property can prevent fires to a certain extent and increase the electrical safety.

[0023] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0024] It should be noted that in the description of the present utility model, all directional indications (such as up, down, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0025] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present utility model, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] As Figures 1-5 shown, a wire terminal includes a connection head 1 and a wiring part 2 integrally connected to the connection head 1. The connection head 1 and the wiring part 2 are integrally in a plate-like structure. The connection head 1 is provided with a mounting hole 4. On the wiring part 2, three upper bow parts 21 that arch upward above the upper end face of the wiring part 2 and three lower bow parts 22 that arch downward below the lower end face of the wiring part 2 are integrally provided. The wiring part 2 includes notches 3 that face inwardly and oppositely at the arching parts of each upper bow part 21 and lower bow part 22. The notches 3 can pass a wire. The number of notches 3 can be one, or multiple notches 3 that are connected to each other through the outside. It only needs to meet that there are notches 3 on the wiring part 2 where the orthographic projections of each upper bow part 21 and lower bow part 22 are located for passing a wire. After wire cutting the wiring part 2, the parts between adjacent wire cuttings can be pressed and bent in different directions to form the upper bow part 21, the lower bow part 22, and the notch 3. Or after cutting through holes in the wiring part 2 to form the notches 3, the upper bow part 21 and the lower bow part 22 in the shape of an arc are welded in opposite directions. The overall structure is simple and the processing cost is low. Each upper bow part 21 and lower bow part 22 can be pressed so that the arching part deforms toward the corresponding notch 3 on the inner side, for squeezing and connecting the wire installed here;

[0027] There is a notch 3 on the inner side of the arching part of each upper arch part 21 and lower arch part 22, so that the wire inclines towards the corresponding notch 3 after being squeezed. Each upper arch part 21 and lower arch part 22 are alternately arranged in sequence along the wire access direction on the wiring part 2, and there are intervals between adjacent upper arch parts 21 and between adjacent lower arch parts 22. When processing or cutting, some extra materials can be left, and at the same time, more waste materials are cut to ensure the cutting quality and surface finish of the processed parts, reduce the processing materials used, and save costs.

[0028] When the wire extends into the notch 3, press the upper arch part 21 and the lower arch part 22 inward on both sides. It can be directly seen from the outside whether the upper arch part 21 and the lower arch part 22 are pressed, so as to ensure that each upper arch part 21 and lower arch part 22 can be in pressing contact with the wire, thereby providing frictional resistance to the wire; and the upper arch part 21 and the lower arch part 22 provide opposite pressure on the wire, making the wire tilt and bend towards the corresponding notch 3. Therefore, the bent part of the wire contacts the side walls of the upper arch part 21 and the lower arch part 22 and is clamped. When pulling the wire outward, the wire can receive a supporting force opposite to the pulling direction, greatly increasing the connection stability of the wire.

[0029] Furthermore, the three alternately arranged upper arch parts 21 and three lower arch parts 22 increase the number of bent segments of the wire, increase the contact area between the inclined and bent part of the wire and the sides of the upper arch part 21 and the lower arch part 22, and increase the number of clamped segments, greatly increasing the maximum supporting force of the upper arch part 21 and the lower arch part 22 on the wire, enabling it to withstand a greater pulling force and making the connection more stable.

[0030] The notch 3 extends reversely along the wire access direction to one end of the wiring part 2 to form an opening, and the opening facilitates the insertion of the wire into the notch 3 without having to detour, making the installation convenient and fast.

[0031] The notch 3 can be a rectangular through-hole as a whole, which is convenient to be cut from a metal plate, with a simple structure and low processing cost.

[0032] The wiring part 2 is coated with an insulating layer. The insulating layer can ensure the safety of electrical connection, can block current conduction, avoid accidental contact between wires or between wires and other conductive components, thereby ensuring the normal operation of the entire electrical system. The material of the insulating layer includes insulating materials that are resistant to high temperature and corrosion. Specifically, PEEK or PU materials can be used. At the same time, functional materials with flame retardant and anti-corrosion functions are adopted, which can isolate external moisture, reduce conductor oxidation, increase the service life of the terminal, and the flame retardant property can prevent fires to a certain extent and increase the electrical safety.

[0033] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
