[0032] Example

[0033] Please refer to Figures 1-6 This embodiment provides an explosion-proof junction box for a pipeline refueling vehicle, comprising: a junction box body 1, the junction box body 1 being a hollow structure, and having a wire inlet 2 and a plurality of wire outlets 3 for passing wires;

[0034] The distribution board 4 includes a base 401, a power supply terminal 402 electrically connected to the power supply, and a plurality of power supply terminals 403. The base 401 is arranged in the junction box body 1, and the power supply terminal 402 and the plurality of power supply terminals 403 are all arranged on the base 401, and the plurality of power supply terminals 403 are respectively electrically connected to the power supply terminal 402.

[0035] In this embodiment, the junction box body 1 is hoisted onto a pipeline refueling truck and is used to accommodate and install a distribution board 4. Transmission wires are routed through the sidewalls of the junction box body 1, facilitating power supply to various auxiliary electrical devices. Specifically, the cable inlet 2 is used to route wires from the pipeline refueling truck's battery to the power transmission terminal 402, while the cable outlet 3 is used to route wires from the auxiliary electrical devices to the power transmission terminal 402. This facilitates the neat and orderly arrangement of transmission wires, facilitating maintenance and the installation of additional auxiliary electrical devices.

[0036] In this embodiment, the distribution board 4 is used to distribute the power drawn from the battery to various auxiliary electrical devices. The wires of each auxiliary electrical device are sequentially crimped to the distribution board 4, meeting the needs of multiple auxiliary electrical devices in simultaneous use and improving the efficiency of wire usage. While branching the wires, the distribution board 4 ensures that the power drawn by each auxiliary electrical device is stable, avoiding power instability caused by excessive loads simultaneously crimped to the battery connectors.

[0037] Please refer to Figure 1-Figure 5 In some implementations of this embodiment, the above-mentioned junction box body 1 includes a bottom groove 101 and a cover body 102. The bottom groove 101 is used to connect to the pipeline refueling truck. The cover body 102 is covered at the mouth of the bottom groove 101. A water retaining plate 5 is circumferentially arranged around the mouth of the bottom groove 101. The abutting end of the cover body 102 and the bottom groove 101 is located on the inner side of the water retaining plate 5.

[0038] In this embodiment, the bottom trough 101 and the cover 102 can be enclosed to form a closed structure, which prevents dust and moisture from entering. When repairing, the cover 102 can be removed to facilitate the repair of the distribution board 4, thereby improving the convenience of repair.

[0039] In this embodiment, the above-mentioned water retaining plate 5 is used to prevent water from entering the interior of the junction box body 1. During installation, the plane where the mouth of the bottom trough 101 is located is perpendicular to the ground, and rainwater will impact the top of the connecting surface between the bottom trough 101 and the cover body 102. The water retaining plate 5 blocks the vertically falling rainwater, preventing the rainwater from impacting the bottom trough 101.

[0040] Furthermore, the water retaining plate 5 is used for aligning and installing the cover 102 and the bottom trough 101, so as to facilitate the rapid docking of the bottom trough 101 and the cover 102 and improve the convenience of installation.

[0041] Please refer to Figure 5 and Figure 6 In some implementations of this embodiment, a sealing strip 6 is provided between the bottom groove 101 and the cover body 102. A receiving groove (not marked in the figure) is circumferentially opened on one side of the bottom groove 101 close to the cover body 102. The sealing strip 6 is arranged in the receiving groove, and the cover body 102 abuts against the sealing strip 6.

[0042] In this embodiment, the above-mentioned sealing strip 6 is used to increase the sealing effect of the docking gap between the cover body 102 and the bottom groove 101. It should be noted that after the above-mentioned cover body 102 and the bottom groove 101 are docked, screws are inserted through the top of the cover body 102 into the side wall of the bottom groove 101 to install the junction box, so that the mouth of the cover body 102 continuously squeezes the sealing strip 6 installed at the mouth of the bottom groove 101, which greatly improves the waterproof and dustproof level of the junction box body 1.

The locking spring 804 is respectively connected to the substrate 801 and the locking buckle 803.

[0047] In this embodiment, the above-mentioned substrate 801 is connected to the base 401 by screws, and there are two positioning buckles 802, which are symmetrically arranged on both sides of the substrate 801. The above-mentioned positioning buckle 802 is provided with a first groove for accommodating the edge of the guide rail 7, and the above-mentioned locking buckle 803 has a second groove adapted to the edge of the guide rail 7. During installation, the second groove of the locking buckle 803 is aligned with the edge of the guide rail 7, and the edge of one side of the guide rail 7 is clamped into the second groove.
