Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically to a European-style terminal block. Background Technology

[0002] Traditional European-style terminals are suitable for manual wire threading and crimping. With the development of technology, wire threading and crimping can now be performed using automated equipment. However, using automated equipment to crimp traditional European-style terminals cannot solve the problem of frequent wire jamming during the threading process.

[0003] European-style terminals use a flared end of a copper tube to fit into the insulating sheath. During threading, loose multi-strand copper wires are compressed through the flared end and forced into the copper tube. An angle misalignment of the multi-strand wires during this process can cause wire obstruction. When manually threading, this obstruction can be corrected by readjusting the angle; however, automated equipment cannot adjust the angle multiple times, leading to malfunctions and shutdowns when wire obstruction occurs. Currently, this is addressed by increasing the flared end, but this increases the probability of copper tube wall breakage and does not completely solve the wire obstruction problem during automated threading. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a European-style terminal that is easy to assemble and has high production efficiency.

[0005] To address the above problems, the following technical solution is provided: A European-style terminal includes a copper tube and an insulating sleeve fitted onto one end of the copper tube. The copper tube has a through mounting hole in its axial direction, and the insulating sleeve has a through connecting hole in its axial direction. The end of the copper tube that mates with the insulating sleeve is the connecting end. The connecting end is flared to form a first flared portion. The first flared portion is flared towards the end of the insulating sleeve to form a second flared portion with a diameter larger than the first flared portion.

[0006] In the above structure, by setting the second flared part at the end of the first flared part, it is possible to avoid the tube wall between the first flared part and the copper tube being too thin and breaking. It can also further increase the diameter of one end of the copper tube, making it easier for the copper wire to pass through the connecting hole and enter the mounting hole of the copper tube for crimping and mating. This greatly reduces the probability of wire blockage, thereby improving the production efficiency of this utility model and reducing the scrap rate of this utility model.

[0007] The present invention is further provided that one end of the connecting hole is provided with a contraction opening adapted to the connecting end.

[0008] The above structure can improve the connection strength between the copper tube and the insulating sleeve, and facilitates the installation of the copper tube in the insulating sleeve for positioning, thereby improving the assembly efficiency of this utility model.

[0009] The present invention is further configured such that the insulating sleeve is bucket-shaped at one end of the connecting end.

[0010] The above structure can further cover the connection end and facilitate the insertion and mating of the present invention with its compatible terminals, thereby improving the reliability and ease of assembly of the present invention.

[0011] The present invention is further configured such that the connecting end is riveted inside the insulating sleeve.

[0012] In the above structure, the copper tube is riveted into the insulating sleeve through a special two-stage conical structure formed by the first flared part and the second flared part, thereby improving the connection strength between the copper tube and the insulating sleeve.

[0013] The present invention is further configured such that the second flared portion is located in the middle of the first flared portion near the insulating sleeve.

[0014] By adopting the above structure, the edge formed by the second flared part on the first flared part is far away from the edge formed by the first flared part on the copper tube, thereby avoiding affecting the wall thickness of the copper tube and improving the robustness of this utility model.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] like Figures 1 to 4 The European-style terminal shown includes a copper tube 1 and an insulating sleeve 2 sleeved on one end of the copper tube 1. The copper tube 1 has a through mounting hole 11 in the axial direction, and the insulating sleeve 2 has a through connecting hole 21 in the axial direction. The end of the copper tube 1 that mates with the insulating sleeve 2 is a connecting end 12. The connecting end 12 is flared to form a first flared portion 121. The first flared portion 121 is flared towards the end of the insulating sleeve 2 to form a second flared portion 122 with a diameter larger than the first flared portion 121.

[0023] In the above structure, by setting the second flared part 122 at the end of the first flared part 121, it is possible to avoid the pipe wall between the first flared part 121 and the copper pipe 1 being too thin and breaking. It can also further increase the diameter of one end of the copper pipe 1, making it easier for the copper wire to pass through the connecting hole 21, pass through the connecting end 12, and enter the mounting hole 11 of the copper pipe 1 for crimping and mating. This greatly reduces the probability of wire blockage, thereby improving the production efficiency of this utility model and reducing the scrap rate of this utility model.

[0024] In this embodiment, one end of the connecting hole 21 is provided with a contraction opening 22 that is adapted to the connecting end 12.

[0025] By adopting the above structure, the connection strength between the copper tube 1 and the insulating sleeve 2 can be improved, and the copper tube 1 can be easily installed in the insulating sleeve 2 for positioning, thereby improving the assembly efficiency of this utility model.

[0026] In this embodiment, the insulating sleeve 2 is located at one end of the connecting end 12 in the shape of a bucket.

[0027] The above structure can further cover the connection end 12 and facilitate the insertion and mating of the present invention with its compatible terminals, thereby improving the reliability and ease of assembly of the present invention.

[0028] In this embodiment, the connecting end 12 is riveted inside the insulating sleeve 2.

[0029] In the above structure, the copper tube 1 is riveted into the insulating sleeve 2 through a special two-stage conical structure formed by the first flared part 121 and the second flared part 122, thereby improving the connection strength between the copper tube 1 and the insulating sleeve 2.

[0030] In this embodiment, the second flared portion 122 is located in the middle of the first flared portion 121 near the insulating sleeve 2.

[0031] By adopting the above structure, the edge formed by the second flared part 122 on the first flared part 121 is far away from the edge formed by the first flared part 121 on the copper tube 1, thereby avoiding affecting the wall thickness of the copper tube 1 and improving the robustness of this utility model.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
