[0031] The power rail socket provided in this embodiment is applied, and the power rail socket includes a seat 10 and a junction box 20. The conductive cable 12 of the seat 10 is arranged in the cable accommodating cavity 111 of the shell 11, so that the conductive cable 12 can extend along the length direction of the shell 11.

In order to ensure that the conductive cable 12 in the seat 10 can be connected with the external power supply cable, a junction box 20 is arranged at one end of the shell 11 along its length direction, and the shell 21 of the junction box 20 is covered on the bottom plate 22, and a cable interface 211 is arranged on the side wall of the shell 21 facing the seat 10, so that the conductive cable 12 in the seat 10 can be inserted into the cable interface 211 and connected to the junction box 20. A carrier 221 is provided on the bottom plate 22 in the junction box 20, and a conductive member 23 is provided on the carrier 221. One of the carrier 221 and the conductive member 23 is provided with a positioning recess 24, and the other of the carrier 221 and the conductive member 23 is provided with a positioning protrusion 25. The positioning protrusion 25 is installed in the positioning recess 24, so that the conductive member 23 can be positioned and installed on the carrier 221, and when the conductive cable 12 is inserted into the cable interface 211, it is electrically connected to the first end of the conductive member 23, and the power supply cable connection portion 28 at the second end of the conductive member 23 is electrically connected to the external power supply cable, so that the external The power supply cable transmits electrical energy to the conductive member 23.

[0035] like Figure 3 As shown, the limiting groove 261 includes a first groove section 2611 and a second groove section 2612 that are connected. The first groove section 2611 is arranged above the second groove section 2612. The cross-sectional size of the first groove section 2611 gradually decreases from top to bottom. The conductive member 23 extends into the second groove section 2612 and is interference fit with the side wall of the second groove section 2612. By adopting the above structure, by setting the first groove section 2611 and the second groove section 2612, the cross-sectional size of the first groove section 2611 gradually decreases from top to bottom, so that the inner wall of the first groove section 2611 can be an inclined surface, so that when the conductive part 23 is installed in the limiting groove 261, the first groove section 2611 can be used to guide the conductive part 23, and the side wall of the second groove section 2612 can be interference fit with the conductive part 23, so that the second groove section 2612 can be used to clamp the conductive part 23, so that the limiting groove 261 can not only guide the conductive part 23, but also play a role in limiting and clamping.

With the above structure, by providing at least two carrier sub-platforms 2211, the interval between two adjacent carrier sub-platforms 2211 along the length direction of the junction box 20 forms a positioning recess 24, so that it is convenient to position and install the conductive member 23 through the interval between the two adjacent carrier sub-platforms 2211, and each carrier sub-platform 2211 is provided with a limiting groove 261, so that when both ends of the conductive member 23 are installed on the two carrier sub-platforms 2211, both ends of the conductive member 23 are guided and limited, thereby ensuring the stability of the limiting structure of the conductive member 23 and the carrier 221.

[0037] It should be noted that the number of the bearing sub-platforms 2211 is set correspondingly according to the number of the conductive cables 12. In this embodiment, the conductive cables include live cables, ground cables and neutral cables, and the corresponding cable interfaces 211 on the housing 21 of the junction box 20 are set to three, and the corresponding conductive members 23 are set to three, and each conductive member 23 is installed and limited by two bearing sub-platforms 2211, so that the live cables, ground cables and neutral cables can be electrically connected through the conductive members 23, ensuring that the external power supply cables can be electrically connected to the electric wire cables.

[0038] like Figures 4 to 6As shown, the conductive member 23 includes a first plate segment 231, a second plate segment 232, a third plate segment 233, a fourth plate segment 234, a fifth plate segment 235 and a sixth plate segment 236 which are connected in sequence.

[0040] It should be noted that the clamping portion 27 includes a first clamping jaw and a second clamping jaw that are arranged opposite to each other, and there is an installation gap between the first clamping jaw and the second clamping jaw, so that one end of the conductive cable 12 can be clamped by the first clamping jaw and the second clamping jaw. Since the installation gap between the first clamping jaw and the second clamping jaw is smaller than the size of the conductive cable 12, the first clamping jaw and the second clamping jaw can move relative to each other to ensure that the conductive cable 12 is clamped. Since the first clamping jaw and the second clamping jaw are elastic, the conductive cable 12 can be clamped after being reset. In order to ensure that the conductive member 23 is electrically connected to the conductive cable 12, the clamping portion 27 is made of copper.

[0041] like Figure 3As shown, two positioning plates 2212 are provided on the side of the carrier 221 facing the base 10, and there is an installation interval between the two positioning plates 2212.

[0043] It should be noted that the external power supply cable is sleeved on the first fastener through the circular terminal. When the first fastener is passed through the connecting hole 281 and threadedly connected with the threaded hole 2213, this can ensure that the circular terminal abuts against the conductive member 23, thereby enabling electrical connection.

[0044] Among them, the bottom plate 22 is provided with L, N, E marks, which facilitates the identification of the installation positions of the live cable, the neutral cable and the ground cable.
