[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0014] like Figure 1-2 The illustrated quick-connect emergency socket includes a front plug 1 and a rear plug 2 arranged in a T-shape. Figure 1 As shown, the T-shaped front plug 1 and rear plug 2 have interface structures at both ends, and quick-release heads are connected at the bottom. The quick-release plug and protective shell 6 structure facilitates disassembly and connection. The interface structures at the top can be quickly and easily connected to each other through the connecting hardware 5 to meet various usage needs.

[0015] Furthermore, as described above, the front plug 1 and rear plug 2 of this embodiment include a molded sheath 11 and an insulating potting layer 12. The molded sheath 11 is provided with a filling hole 9 for pouring in liquid resin that solidifies to form the insulating potting layer 12. During production, the molded sheath 11 is clamped by tooling to form an insulating cavity. Then, the prepared cross-linked material or insulating resin material is poured in and allowed to solidify to form an insulating potting layer 12 that covers the internal electrical terminals 4. The outer side is also covered by the molded sheath 11. The structure is stable and durable and easy to produce.

[0016] As described above, in this embodiment, the electrical terminals 4 are fixedly installed in the front plug 1 and rear plug 2 by material fixation. The electrical terminals 4 on the front plug 1 and rear plug 2 are fitted with double-ended bolts 3. During connection, the double-ended bolts 3 pass through the pre-drilled connection holes on the electrical terminals 4 to connect to the sleeve hole 15 or the interface 21 and the rear interface 22. The two double-ended bolts 3 are electrically connected by connecting fittings 5, forming a structure as shown above. Figure 1 The usage and matching state is shown.

[0017] As a further feature of the above solution, the front plug 1 includes a sleeve hole 15 and a rear interface 22. The rear plug 2 is provided with a mating interface 21 and a rear interface 22, which are correspondingly plugged into each other. The front plug 1 and the rear plug 2 are also provided with plug caps 8, which are matched with the rear interface 22. The mating interface 21 and the rear interface 22 are matched and sleeved together. During connection, the double-ended bolts 3 installed on the electrical terminals 4 are connected end to end by connecting hardware 5 to transmit signals and current. It is worth noting that at the end of the connection, the plug caps 8 can be used to seal the front plug 1 and the rear plug 2, which can play a role in dust prevention and protection.

[0018] As a further provision of the above solution, in this embodiment, the lower end of the electrical terminal 4 extends out of the front plug 1 and the rear plug 2 and is provided with a connection port 7. The front plug 1 and the rear plug 2 are provided with a quick-release plug housing 6 opposite to the connection port 7. The quick-release plug housing 6 includes a mounting part 69 and a plug protective shell 62. The mounting part 69 is provided with a ball bearing 63 and a radial limiting ring 61. The radial limiting ring 61 is provided with a return spring that is axially telescopically movable relative to the front plug 1 and the rear plug 2. The mounting part 69 is provided with a slot that matches the ball bearing 63. The plug protective shell 62 is provided with a corresponding limiting groove 66. The radial limiting ring 61 is provided with an axial limiting cover 65. The plug protective shell 62 includes a plug post 67, which is inserted into the slot of the connection port 7. Figure 2 As shown, in this embodiment, the quick-release plug housing 6 has a ball bearing 63 that is engaged in the groove of the mounting part 69. When the plug housing 62 is inserted, the operator needs to move the radial limiting ring 61 towards the groove. Figure 2The upward push causes the radial limiting ring 61 behind the ball 63 to shift away from the inner wall, allowing the ball 63 to move outward. This allows the maximum diameter of the plug protective shell 62 to be inserted. Meanwhile, the spring 64 continuously exerts its restoring force, pushing the radial limiting ring 61 downward. However, because the ball 63 moves outward and is held in place by the plug protective shell 62, the ball 63 obstructs the axial movement of the radial limiting ring 61. When the protective shell 62 is inserted into the limiting groove 66 and aligned with the ball 63, the ball 63 can move inward, thereby releasing the axial obstruction of the radial limiting ring 61. The radial limiting ring 61 moves downward based on the elastic force of the spring 64. After the ball 63 is inserted into the limiting groove 66, the radial limiting ring 61 abuts against the outer side of the ball 63, thus limiting the axial movement of the plug protective shell 62. During disassembly, the radial limiting ring 61 can be pushed upward and the plug protective shell 62 can be pulled outward to remove it quickly.

[0019] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
