Abstract
Description
Technical Field
[0001] The present application relates to the technical field of wiring terminals, and in particular to a reliable incoming line European-style terminal. Background Art
[0002] At present, European terminals are also called European wiring terminals. They are electronic components mainly used to connect electrical circuits and equipment. Its main function is to connect wires to electrical equipment, thereby playing the role of signal connection. European terminals usually adopt a pluggable design, so the line can be easily and quickly removed and replaced, making maintenance and upgrade work more convenient. European terminals can also be used for the connection of multiple wires, including single-core wires, double-core wires, multi-core wires, etc.
[0003] In the related art, there is a European-style terminal, whose main structure includes an insulating sheath and a conductive part fixedly mounted on the insulating sheath at one end. An inlet for inserting the power line is formed at the end of the insulating sheath away from the conductive part. The inner diameter of the inlet is usually larger than the outer diameter of the wire to be installed. After inserting the wire from the inlet into the insulating sheath, it is necessary to ensure that the core of the wire is inserted into the conductive part, and finally the conductive part is squeezed by a wire crimping pliers, and finally the core of the wire will be pressed and fixed in the conductive part, thereby completing the wiring work.
[0004] However, when the wire core has not been pressed and fixed in the conductive member, the wire is very easy to be separated from the insulating sheath when pulled by external force, which will have a certain impact on the subsequent wire fixing and make it inconvenient to carry out the smooth wire fixing work.

[0008] By adopting the above technical solution: after the wire fixing piece is plugged and fixed in the wire inlet of the insulating sheath, the wire is inserted from one side of the wire threading hole, and then passed through the limiting hole into the insulating sheath.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.
[0024] The embodiment of the present application discloses a reliable incoming line European-style terminal.
[0025] Reference Figure 1 , Figure 2 The reliable European-style terminal includes a conductive plug 2 and an insulating sheath 1 injection-molded at one end of the conductive plug 2. The end of the insulating sheath 1 away from the conductive plug 2 is formed with an inlet for inserting a power line.
[0026] like Figure 2 , Figure 3 As shown, it also includes a wire fixing member 3 for being inserted and fixed in the wire inlet of the insulating sheath 1. A threading hole 30 for the power line to be inserted into the insulating sheath 1 is passed through the central axis of the wire fixing member 3. A plurality of pressing plates 31 located in the insulating sheath 1 are integrally formed on the outer wall of the wire fixing member 3 away from the wire inlet of the insulating sheath 1. Each pressing plate 31 is evenly spaced around the central axis of the threading hole 30 and is arranged around the threading hole 30 in a circumferential direction. One end of the pressing plate 31 is integrally formed on the outer wall of the wire fixing member 3, and the other end of the pressing plate 31 extends in a direction close to the central axis of the threading hole 30 and is inclined in a direction away from the threading hole 30. A limiting hole 32 for the power line to be passed through is formed around the ends of each pressing plate 31 close to each other. The pressing plate 31 is made of plastic with a certain elastic deformation ability. The limiting hole 32 is used to limit and fix the wire in the insulating sheath 1.
[0027] like Figure 2 , Figure 3 As shown, the side wall of the wire fixing member 3 facing the insulating sheath 1 is circumferentially provided with slots 33, the slots 33 are coaxially arranged with the threading hole 30, and the slots 33 are used for inserting the end outer wall of the insulating sheath 1 into the wire fixing member 3. When the wire fixing member 3 is installed, the end outer wall of the insulating sheath 1 is aligned and inserted into the slots 33, and the wire fixing member 3 can be fixed on the insulating sheath 1 in a limited position.
[0028] like Figure 2 , Figure 3 As shown, a stop ring 10 for inserting into the slot 33 is integrally formed on the circumferential outer wall of the insulating sheath 1 close to the wire fixing member 3, and the stop ring 10 inserted into the slot 33 contacts the inner wall of the slot 33. The connection reliability between the wire fixing member 3 and the insulating sheath 1 is further enhanced by the mutual plug-in cooperation between the stop ring 10 and the slot 33, and the installation is convenient and quick.
[0029] like Figure 2 , Figure 3 As shown, a drainage surface 34 located outside the insulating sheath 1 is integrally formed on the circumferential outer wall of the wire fixing member 3 away from the wire inlet of the insulating sheath 1, and the drainage surface 34 is inclined inwardly toward the direction close to the central axis of the insulating sheath 1. When rainwater flows toward the wire fixing member 3 along the outer wall of the insulating sheath 1, the drainage surface 34 can drain the flowing rainwater, so that the rainwater can be discharged from the wire fixing member 3 as soon as possible, effectively preventing the accumulation of rainwater on the wire fixing member 3.
[0030] like Figure 2 , Figure 3 As shown, a guide slope 11 is integrally formed on the inner wall of the wire inlet of the insulating sheath 1 , and the guide slope 11 is inclined toward the direction close to the central axis of the insulating sheath 1 . The guide slope 11 is used to guide the wire fixing piece 3 to be inserted into the insulating sheath 1 more smoothly.
[0031] like Figure 2 , Figure 3 As shown, a lead wire slope 12 is integrally formed on the inner wall of the insulating sheath 1 near the conductive plug 2, one side of the lead wire slope 12 is connected to the conductive plug 2, and the lead wire slope 12 is inclined in the direction close to the conductive plug 2. After the wire is inserted into the insulating sheath 1, the lead wire slope 12 can guide the wire core to be inserted into the conductive plug 2 more smoothly.
[0032] like Figure 2 , Figure 3 As shown, a limiting groove 13 connected to one side of the lead bevel 12 is integrally formed on the inner wall of the insulating sheath 1, and the outer wall of the end of the conductive plug 2 is inserted into the limiting groove 13, and the shape of the limiting groove 13 is adapted to the shape of the end of the conductive plug 2. The mutual plug-in cooperation between the limiting groove 13 and the outer wall of the end of the conductive plug 2 can further enhance the connection reliability of the connection between the insulating sheath 1 and the conductive plug 2.
[0033] The implementation principle is: after the wire fixing piece 3 is plugged and fixed in the wire inlet of the insulating sheath 1, the wire is inserted from one side of the wire threading hole 30, and then passed through the limiting hole 32 into the insulating sheath 1. At this time, the wire can be stably and firmly fixed in the insulating sheath 1 under the limitation of the surrounding pressure plate 31, thereby effectively preventing the wire from escaping from the insulating sheath 1 and ensuring the connection reliability of the incoming line.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
