Description

Technical Field

[0001] The utility model belongs to the technical field of connecting terminals, in particular to a half-moon ring metal wire connecting terminal. Background Art

[0002] A terminal assembly is usually composed of a wire and a terminal connected to the wire; the wire and the terminal not only need to form a stable connection structure, but also need to form an electrical connection, so as to transmit electrical signals such as data to another connector connected to the terminal assembly; in order to form a reliable electrical connection between the wire and the terminal, the existing metal wire connection terminal usually connects one end of the metal wire to the first terminal first, and then connects the other end of the metal wire to the second connection terminal during the connection process; specifically, the metal wire and the terminal are connected together by a riveting process.

[0003] There are two disadvantages of this terminal block and wiring method. First, the wiring efficiency is low, and each metal wire needs to be connected to the terminal block through two riveting operations. Second, the connection between the metal wire and the terminal block is not stable enough. The conventional riveting method is to make the surface contact between the metal wire and the crimping part, but when the diameter of the metal wire is very thin, this surface contact is very unstable. The metal wire is not easy to slip off the crimping part.

[0004] Based on the above problems, there is a method in the prior art that can realize the rapid fixing of the terminal and the metal wire, such as the Chinese patent document "CN109786994A, a back-to-back metal wire connection terminal, assembly and wiring method of the assembly"; point contact connection with the metal wire is achieved by riveting, and the terminal is divided into two after one riveting, so that two terminals can be quickly formed;

[0005] However, the fixed parts of the terminals are connected by connecting parts, which cannot be removed during cutting, resulting in partial protrusion of the formed terminals, which not only causes waste but also poses a safety hazard. In addition, in actual applications, the fixed parts of the terminals do not need to be in a closed shape, which undoubtedly increases processing costs. Utility Model Content

[0013] Beneficial effects of the utility model:

Specifically, after the annular fixing portion 1 is cut, two independent terminals are formed, and both terminals are open and respectively connected to the first riveted portion 2 and the second riveted portion 3; through such an arrangement, the use is not affected, and the connection portion will not protrude like the prior art, and the manufacturing cost is lower. Of course, the fixing portion 1, the first riveted portion 2 and the second riveted portion 3 are an integrated structure.

[0025] The usage based on the above structure is as follows:

[0026] S1: placing a metal wire on the fixing portion 1, the first riveted portion 2 and the second riveted portion 3 at the same time; and curling the first riveted portion 2 and the second riveted portion 3 under the action of an external force until the metal wire is tightly pressed;

[0028] S3: Repeat the above two steps for many times until a predetermined number of n half-moon ring metal wire connection terminals are connected in series on the metal wire, and then cut the fixing portion 1 into two semicircles to obtain n-1 sections of metal wire.

[0029] The closed annular fixing portion 1 described in the present embodiment may be in the shape of a Chinese character "U", an elliptical ring, etc., preferably a circular ring. When the fixing portion 1 is cut, an open half-moon structure can be formed.

[0030] In this embodiment, after the metal wire is placed in the half-moon ring metal wire connecting terminal, the first riveted part 2 and the second riveted part 3 are operated simultaneously by riveting, and after the metal wire is connected to the two riveted parts at the same time, the fixed part 1 is cut, so that one riveted part is connected to the end of the previous section of the metal wire, and the next riveted part is connected to the front end of the next section of the metal wire; the entire wiring process is efficient; and the riveted part and the metal wire adopt a multi-point contact method, so the connection is more stable.

When in use, the plurality of third metal sheets 33 are curled and pressed against the metal wire by external force, and the curled staggered respectively squeeze the metal wire. Since the contact area between each third metal sheet 33 and the metal wire is small, a "W"-shaped layout fixing method is formed at the same time to achieve multi-point contact.
