Description

Technical Field

[0001] The present application relates to the technical field of wiring terminals, and in particular to a two-wire European-style terminal. Background Art

[0002] Euro-style terminals, also known as European-style wiring terminals, are electronic components primarily used to connect electrical circuits and equipment. Their primary function is to connect wires to electrical equipment, thereby providing signal connections. Euro-style terminals typically feature a pluggable design, allowing for quick and easy removal and replacement of wires, facilitating maintenance and upgrades. Euro-style terminals are also suitable for connecting multiple wires, including single-core, dual-core, and multi-core wires.

[0003] In the related art, there is a two-wire European-style terminal, which mainly includes an insulating sheath and a conductive member fixed on the insulating sheath at one end. The end of the insulating sheath away from the conductive member is formed with an inlet for inserting two wires at the same time.

[0004] For the above-mentioned two-wire European-style terminal, since the wire inlet is an open structure, when two wires are inserted into the insulating sheath at the same time, there will inevitably be a gap between the cable and the inner wall of the wire inlet. External rainwater can easily flow into the insulating sheath through the gap between the two, thereby greatly reducing the waterproof sealing performance of the insulating sheath.

[0023] The present application is further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the present application discloses a two-wire European-style terminal.

[0025] Reference Figure 1 、 Figure 2 The double-wire European terminal includes a conductive part 2 and an insulating sheath 1 injection-molded at the end of the conductive part 2. An end of the insulating sheath 1 away from the conductive part 2 is formed with an inlet for multiple wires to be inserted into the insulating sheath 1 at the same time.

[0026] like Figure 2 、 Figure 3 As shown, the insulating sheath 1 also includes a sealing cover 3 for covering the wire inlet. The sealing cover 3 is made of plastic or rubber with a certain degree of elastic deformation. The shape of the sealing cover 3 is adapted to the shape of the wire inlet of the insulating sheath 1. The sealing cover 3 has two threading holes 30 through which the power wires are respectively inserted into the insulating sheath 1.

[0027] like Figure 2 、 Figure 3 As shown, a limiting ring 31 is integrally formed on the circumferential outer wall of the sealing cover 3, and a limiting groove 10 for inserting the limiting ring 31 is provided on the circumferential inner wall of the insulating sleeve 1, and the shape of the limiting groove 10 is adapted to the shape of the limiting ring 31; the limiting ring 31 inserted into the limiting groove 10 is interference fit with the insulating sleeve 1, and the sealing cover 3 can be stably and firmly fixed on the insulating sleeve 1 through the mutual plug-in cooperation of the limiting ring 31 and the limiting groove 10. At this time, the sealing cover 3 can seal the line inlet of the insulating sleeve 1.

[0028] like Figure 2 、 Figure 3 As shown, a fixing groove 300 is coaxially provided on the circumferential inner sidewall of the threading hole 30. A sealing ring 4 is mounted on the sealing cover 3 through the fixing groove 300. The sealing ring 4 is coaxially arranged with the fixing groove 300 and is fixed in its respective fixing groove 300. The sealing ring 4 is made of elastically deformable rubber. By threading the wires through the sealing ring 4, the inner sidewall of the sealing ring 4 will abut and contact the outer sidewall of the wires. The sealing ring 4 can further enhance the waterproof sealing performance of the threading hole 30, preventing rainwater from entering the insulating sheath 1 along the wires.

[0029] like Figure 2、 Figure 3 As shown, a baffle 32 is coaxially integrally formed on the circumferential outer wall of the sealing cover 3. When the sealing cover 3 is installed on the insulating sheath 1, the baffle 32 will be located outside the insulating sheath 1, and the baffle 32 will fit together with the outer wall where the opening surface of the insulating sheath 1 is located. The baffle 32 can further improve the waterproof sealing of the opening of the insulating sheath 1.

[0030] like Figure 2 、 Figure 3 As shown, a first guide slope 11 is circumferentially provided on the inner side wall of the opening surface of the insulating sheath 1; when the sealing cover 3 is installed on the insulating sheath 1, the first guide slope 11 is used to contact the limiting ring 31 and guide the limiting ring 31 to be inserted into the insulating sheath 1 more smoothly.

[0031] like Figure 2 、 Figure 3 As shown, a second guide slope 12 is also circumferentially arranged on the inner wall of the insulating sheath 1. The second guide slope 12 is connected to the conductive part 2 on the side away from the opening surface of the insulating sheath 1. The second guide slope 12 is used to guide the wire core inserted into the insulating sheath 1 to be inserted into the conductive part 2 more smoothly.

[0032] like Figure 2 、 Figure 3 As shown, an anti-slip groove 13 is integrally formed on the inner wall of the insulating sheath 1 in a circumferential direction, and the circumferential outer wall of the end of the conductive part 2 is inserted into the anti-slip groove 13. By mutual plug-in cooperation between the anti-slip groove 13 and the end of the conductive part 2, the structural strength of the connection between the insulating sheath 1 and the conductive part 2 can be further improved, so that the end of the conductive part 2 is more stably and firmly arranged on the insulating sheath 1.

[0033] The implementation principle is: insert the wire into the insulating sheath 1 through the sealing ring 4, and at this time cover the wire inlet of the insulating sheath 1 through the sealing cover 3, so as to greatly reduce the probability of rainwater entering the insulating sheath 1 from the wire inlet of the insulating sheath 1, thereby improving the waterproof sealing of the insulating sheath 1, and also improving the safety during use.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
