Description

Technical Field

[0001] This utility model relates to the field of cold-pressed terminal technology, and specifically to a cold-pressed terminal that is easy to install. Background Technology

[0002] Cold-pressed terminals include electronic connectors and air connectors. They are accessory products used to achieve electrical connections and are classified as connectors in the industry. Circular pre-insulated terminals are one type of cold-pressed terminal specification. With increasing industrial automation and more stringent and precise industrial control requirements, the use of terminal blocks is gradually increasing. The front end of a ring-shaped cold-pressed terminal is a closed metal ring with standard diameter holes (such as M3 / M4 / M5), which is fixed to the terminal block of the equipment using a nut.

[0003] For example, Chinese Patent Publication No. CN218940185U discloses a novel cold-pressed terminal, the structure of which includes a connector, a first insulating sleeve, and a second insulating sleeve. The second insulating sleeve is located at the lower end of the first insulating sleeve. The bottom of the connector penetrates the first insulating sleeve and extends into the second insulating sleeve. A conductive element is movably installed inside the second insulating sleeve. A wire is connected to the second insulating sleeve and connected to a positioning plate. The positioning plate transmits current to the connector by cutting the conductive rod. Then the connector is connected to the electrical equipment. When a fault occurs and the connection needs to be disconnected, a gloved worker can first press the second insulating sleeve firmly. The second insulating sleeve deforms, and the positioning plate in the interlayer drives the cutting element to move towards the cutting conductive rod and make contact. This allows the cutting element to cut the cutting conductive rod through the cutting groove, interrupting the current transmission, and then proceeding with the subsequent disconnection from the electrical equipment, effectively preventing dangerous situations from occurring.

[0004] However, when installing cold-pressed terminals, as mentioned above, it is usually necessary to completely unscrew the nut on the terminal block, fit the annular mounting part on the terminal block onto the terminal block, and then screw the nut onto the terminal block and tighten it to lock the mounting part onto the terminal block, resulting in low efficiency during operation.

[0005] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0006] The present invention provides a cold-pressed terminal that is easy to install, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cold-pressed terminal that is easy to install includes a cold-pressed terminal body. The cold-pressed terminal body includes a mounting part and a wiring part. The mounting part also includes an arc-shaped part integrally formed on the top and a semi-annular sleeve hinged to one side of the arc-shaped part. A spring sheet is embedded on one side of the rear part of the arc-shaped part. A connecting groove is opened on one side of the rear part of the semi-annular sleeve. One end of the spring sheet is disposed in the connecting groove. A slot is opened on the other side of the arc-shaped part. A locking block is provided on the other side of the semi-annular sleeve. The locking block is locked into the slot.

[0009] Preferably, the wiring portion is covered with an insulating sleeve.

[0010] Preferably, one side of the arc-shaped portion is provided with a hinge portion one, and one side of the semi-annular sleeve is provided with a hinge portion two that cooperates with the hinge portion one.

[0011] Beneficial effects

[0012] The above-mentioned technical solutions of one or more of the cold-pressed terminals that are easy to install provided by this utility model embodiment have at least one of the following technical effects:

[0013] This utility model, through the above-described technical solution, allows for installation by rotating the semi-circular sleeve to one side to open it, causing the spring plate to deform and store energy. This allows the terminal to enter the mounting part through the gap between the semi-circular sleeve and the arc-shaped part. When the semi-circular sleeve is released, the spring plate releases its elastic energy, causing the semi-circular sleeve to rotate and reset. Tightening the nut locks the mounting part onto the terminal, completing the installation. For disassembly, loosening the nut and pulling the cold-pressed terminal body causes the semi-circular sleeve to rotate to one side, allowing the terminal to be removed through the gap between the semi-circular sleeve and the arc-shaped part. This eliminates the need to completely unscrew the nut from the terminal when installing or disassembling the cold-pressed terminal, thus improving operational efficiency.

[0024] like Figure 1-4 As shown, it is a structural schematic diagram of a preferred embodiment of the present invention, which is an easy-to-install cold-pressed terminal.

[0025] In this embodiment, a cold-pressed terminal body 1 is included. The cold-pressed terminal body 1 includes a mounting part 2 and a wiring part 3. The wiring part 3 is used to connect to a wire, and the mounting part 2 is used to connect to a terminal block. The mounting part 2 also includes an arc-shaped part 4 integrally formed at the top and a semi-annular sleeve 5 hinged to one side of the arc-shaped part 4. The arc-shaped part 4 and the semi-annular sleeve 5 are used to cooperate with the terminal block. A spring plate 6 is embedded on one side of the rear of the arc-shaped part 4, and a connecting groove 7 is opened on one side of the rear of the semi-annular sleeve 5. One end of the spring plate 6 is disposed in the connecting groove 7. The spring plate 7 is used to provide elastic force between the arc-shaped part 4 and the semi-annular sleeve 5 to reset the semi-annular sleeve 5. A slot 8 is opened on the other side of the arc-shaped part 4, and a locking block 9 is provided on the other side of the semi-annular sleeve 5. The locking block 9 is inserted into the slot. Within 8, the semi-circular sleeve and the arc-shaped part 4 are positioned and limited by the cooperation of the locking block 9 and the locking groove 8. During installation, the semi-circular sleeve 5 is rotated to one side to open, and the spring plate 6 deforms and stores energy, allowing the terminal to enter the mounting part 2 through the gap between the semi-circular sleeve 5 and the arc-shaped part 4. At that time, the semi-circular sleeve 5 is released, and the spring plate 6 releases elastic energy to drive the semi-circular sleeve 5 to rotate and reset. Tightening the nut locks the mounting part 2 onto the terminal to complete the installation. During disassembly, the nut is loosened, and the cold-pressed terminal body 1 is pulled to make the semi-circular sleeve 5 rotate to one side to open. At that time, the terminal can be taken out from the gap between the semi-circular sleeve 5 and the arc-shaped part 4. Thus, when installing and disassembling the cold-pressed terminal, it is not necessary to completely unscrew the nut from the terminal, which improves the operation efficiency.

[0026] In this embodiment, the wiring part 3 is covered with an insulating sleeve 10 to provide insulation protection for the wiring part 3.

[0027] In this embodiment, a hinge part 11 is provided on one side of the arc-shaped part 4, and a hinge part 2 12 is provided on one side of the semi-annular sleeve 5 to cooperate with the hinge part 11. The hinge part 11 and the hinge part 2 12 are hinged together to realize that the semi-annular sleeve 5 is hinged to one side of the arc-shaped part 4, so that the semi-annular sleeve 5 can be rotated and opened.

[0028] The present invention provides a cold-pressed terminal that is easy to install. Its installation method, connection method, or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.
