[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, a compact power distributor comprises a compact power distributor 1; a receiving head 2 is fixedly connected to the bottom end of the compact power distributor 1; a plurality of output heads 3 are installed on the top end of the compact power distributor 1; a plurality of heat sinks 4 are fixedly connected to the side ends of the compact power distributor 1; a heat dissipation groove 6 is provided inside the heat sink 4; a plurality of heat dissipation holes 5 are provided inside the heat sink 4, and the heat dissipation holes 5 are communicated with the heat dissipation groove 6.

[0021] After the receiving head 2 and the output head 3 are connected during operation, the compact power distributor 1 will continue to generate heat during operation. If the heat cannot be dissipated in time, it will affect the normal operation. The heat sink 4 is made of a good heat-absorbing material. Multiple groups of heat sinks 4 can absorb the heat of the compact power distributor 1 and cooperate with the external airflow for heat dissipation. The airflow can enter the internal flow of the heat dissipation groove 6 to take away the heat of the heat sink 4. The heat dissipation holes 5 can make the airflow flow, thereby improving the heat dissipation effect of the heat sink 4, thereby improving the heat dissipation effect of the compact power distributor 1 and reducing the damage of the components of the compact power distributor 1 due to heat.

[0022] A positioning plate 8 is installed inside the compact power distributor 1; an output head 3 is fixedly connected to the top of the positioning plate 8; a positioning groove is opened inside the positioning plate 8; a pull rod 9 is slidably connected inside the compact power distributor 1; a slide rod 10 is fixedly connected to the side end of the pull rod 9; a limit plate 13 is fixedly connected inside the compact power distributor 1, and the slide rod 10 is slidably connected inside the limit plate 13; a positioning plug plate 12 is fixedly connected to the side end of the slide rod 10, and the positioning plug plate 12 corresponds to the positioning groove; a positioning spring 11 is fixedly connected to the side end of the limit plate 13, and a slide rod 10 is provided inside the positioning spring 11.

[0023] When the output head 3 is damaged, the pull rod 9 can be pulled to slide. The sliding of the pull rod 9 causes the slide bar 10 to slide. The sliding of the slide bar 10 causes the positioning plate 12 to slide and the positioning spring 11 to contract. At this time, the positioning plate 8 is released for replacement. Then, the new positioning plate 8 is installed inside the compact power distributor 1. The positioning plate 12 is inserted into the positioning groove inside the positioning plate 8 through the elasticity of the positioning spring 11. The position of the positioning plate 8 is fixed by the positioning plate 12, which facilitates the replacement of the output head 3.

[0024] A slide groove 14 is provided inside the compact power distributor 1 ; a positioning L-plate 15 is slidably connected to the slide groove 14 ; a connecting groove is provided inside the output head 3 , and the connecting groove corresponds to the positioning L-plate 15 .

[0025] When the new output head 3 is installed on the compact power distributor 1, the positioning L plate 15 on the sliding groove 14 is inserted into one end of the positioning L plate 15 into the connecting groove inside the output head 3. The position of the output head 3 is limited by the positioning L plate 15, and the positioning plug plate 12 is used to improve the fixity of the position of the output head 3, which also facilitates the replacement of the output head 3.

[0026] A heat dissipation cavity is provided inside the compact power distributor 1 ; a plurality of heat collecting plates 7 are fixedly connected inside the heat dissipation cavity.

[0027] There are heat dissipation cavities at both ends of the compact power distribution machine 1, and the external air flow can enter the heat dissipation cavity and flow. The heat collecting plate 7 can absorb the heat of the compact power distribution machine 1. The heat collecting plate 7 cooperates with the heat sink 4 to improve the heat dissipation effect of the compact power distribution machine 1, and multiple surfaces of the compact power distribution machine 1 can be heat-dissipated.

[0028] A magnet sheet No. 1 is fixedly connected to the side end of the positioning L plate 15 ; an output head 3 is connected to one side of the magnet sheet No. 1.

[0029] When one end of the positioning L-plate 15 is inserted into the connecting slot of the output head 3, the second magnet sheet of the positioning L-plate 15 is attracted to the connecting slot by magnetic attraction, preventing the positioning L-plate 15 from sliding out of the connecting slot at will during operation, thereby improving the fixation of the positioning L-plate 15 on the position of the output head 3.

[0030] The side end of the positioning plug plate 12 is fixedly connected to a second magnet sheet, and the side end of the second magnet sheet is connected to a positioning plate 8 .

[0031] When the positioning plug plate 12 is inserted into the positioning groove through the positioning spring 11, the No. 1 magnet sheet at the side end of the positioning plug plate 12 absorbs the positioning plate 8 through magnetic attraction, thereby improving the connection stability between the positioning plug plate 12 and the positioning plate 8.

[0032] The working principle of the utility model: after the receiving head 2 and the output head 3 are connected during operation, the compact power distributor 1 will continue to generate heat during operation. If the heat cannot be dissipated in time, it will affect the normal operation. The heat sink 4 is made of a good heat-absorbing material. Through multiple groups of heat sinks 4, the heat of the compact power distributor 1 can be absorbed. The heat is dissipated in conjunction with the external airflow. The airflow can enter the internal flow of the heat dissipation groove 6 to take away the heat of the heat sink 4. The heat dissipation hole 5 can make the airflow flow, improve the heat dissipation effect of the heat sink 4, and thus improve the heat dissipation effect of the compact power distributor 1. The compact power distributor 1 has a heat dissipation cavity at both ends, and the external airflow can flow into the heat dissipation cavity. The heat collecting sheet 7 can absorb the heat of the compact power distributor 1. The heat collecting sheet 7 cooperates with the heat sink 4 to improve the heat dissipation effect of the compact power distributor 1, and the compact power distributor 1 can be heat-dissipated on multiple surfaces. When the output head 3 is damaged, the pull rod 9 can be pulled to slide, and the sliding of the pull rod 9 causes the sliding rod 10 to slide, and the sliding of the sliding rod 10 causes the sliding of the positioning plate 12 and the contraction of the positioning spring 11. At this time, the positioning plate 8 is released for replacement, and then the new positioning plate 8 is installed inside the compact power distributor 1, and then the positioning plug plate 12 is inserted into the positioning groove inside the positioning plate 8 by the elasticity of the positioning spring 11, and the position of the positioning plate 8 is fixed by the positioning plug plate 12, so as to facilitate the replacement of the output head 3; when the positioning plug plate 12 is inserted into the positioning groove by the positioning spring 11, the No. 1 magnet sheet at the side end of the positioning plug plate 12 absorbs the positioning plate 8 by the magnetic attraction, thereby improving the connection stability between the positioning plug plate 12 and the positioning plate 8; when the new output head 3 is installed to the compact power distributor 1 After the machine 1 is installed, the positioning L-plate 15 on the sliding groove 14 is inserted into the connecting groove inside the output head 3. The position of the output head 3 is limited by the positioning L-plate 15, and the positioning plug plate 12 is used to improve the fixation of the position of the output head 3, which is also convenient for replacing the output head 3; when one end of the positioning L-plate 15 is inserted into the connecting groove of the output head 3, the No. 2 magnet sheet of the positioning L-plate 15 is adsorbed into the connecting groove through the magnetic attraction, which prevents the positioning L-plate 15 from sliding out of the connecting groove at will during operation, thereby improving the fixation of the output head 3 position by the positioning L-plate 15.

All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
