[0002] A contactor is an "automatic switch" that uses a smaller current to control a larger current and plays roles such as automatic regulation, safety protection, and circuit conversion in a circuit. As a type of contactor, a DC contactor is mainly applied to DC circuits. With the continuous development of power technology, in industries such as new energy vehicles, construction machinery, solar energy, and wind energy equipment, DC power supply systems with DC contactors have been widely used. For example, in the DC charging circuit of new energy vehicles, a high-voltage DC contactor has become an important power distribution control device in this circuit.

[0003] In order to improve the use efficiency and available charging power of the charging system, a matrix switch is generally used in the charging system to control the flexible combined parallel output of charging modules. When the contactor installation method is mainly for the switch assembly during installation, it is necessary to set reserved holes on the installation plate, align the reserved holes with the installation holes at the four corners of the plastic shell switch, and install them with screws. However, when installing this existing installation structure, it is necessary to align the reserved holes and the installation holes, which requires a high degree of accuracy. During installation, it is necessary to continuously calibrate and align the reserved holes and the installation holes, which is rather troublesome and the installation speed is slow.

[0018] As Figure 1 and Figure 2 shown,

[0019] As an optional embodiment,

[0020] A power distribution switch assembly includes a first mounting base 1. First sliders 2 are mounted on opposite sides of the first mounting base 1. An installation bar 4 is mounted between the two first sliders 2. First chutes are formed on the front and rear sides of the installation bar 4. An electric control switch 5 is provided on the first installation bar 4. A sleeve 10 is provided between the electric control switch 5 and the installation bar 4. The sleeve 10 is fixedly connected to the electric control switch 5. Two springs 11 are installed inside the sleeve 10. A pull rod 9 is inserted through the two springs 11. A limiting piece 8 that cooperates with the first chute is mounted at the end of the pull rod 9.

[0021] Specifically, to facilitate the rapid assembly of the electric control switch 5, the above installation method is selected. Among them, the first mounting seat 1 is fixedly installed in the electric control cabinet body. When the power needs to be adjusted later, the corresponding equipment can be stopped by controlling the electric control switch 5 to facilitate centralized power supply, and the output power can be adjusted according to requirements to meet different electricity consumption needs. In addition, in order to ensure that the electric control switch 5 can be quickly connected to the first mounting seat 1, an installation strip 4 and a connecting component cooperating with the installation strip 4 are designed. The connecting component includes a sleeve 10, two springs 11, two pull rods 9 and two limit pieces 8. Among them, the sleeve 10 is installed on the electric control switch 5 between the installation strip 4 and the electric control switch 5. The two pull rods 9 can slide relative to the sleeve 10. A limit piece 8 is installed at the end of each pull rod 9. When the upper and lower two pull rods 9 are pulled away from each other later, the two springs 11 are compressed, and the distance between the two limit pieces 8 increases, and then they are snapped into the first chute. After the external force disappears, the compressed springs 11 are relied on to push the distance between the two limit pieces 8 to shorten, so as to lock the limit pieces 8 in the first chute, thus realizing the connection work. It should be noted that a leftward or rightward acting force can also be applied to drive the electric control switch 5 to displace on the installation strip 4 so as to adjust the installation position of the electric control switch 5, so as to reasonably optimize the internal space of the first mounting seat 1.

[0022] As Figure 1 shown, the connection between the first slider 2 and the first mounting seat 1 is as follows: a first through hole is opened at the center of the top of the first slider 2, and at least two first threaded holes 101 cooperating with the first through hole are opened on the first mounting seat 1. A first threaded rod 3 cooperating with the first threaded hole 101 is installed in the first through hole. By passing the first threaded rod 3 through the first through hole of the first slider 2 and then threadedly connecting it in the first threaded hole 101 of the first mounting seat 1, the first slider 2 can be ensured to be fixed on the first mounting seat 1. And a plurality of first threaded holes 101 are opened on the first mounting seat 1, so the position of the first slider 2 can be adjusted later. Subsequently, the distance between the front and rear two installation strips 4 can be changed by changing the positions of the left and right two first sliders 2.

[0023] As Figure 1 shown, a lifting and adjusting structure is also designed to adjust the distance between the installation strip 4 and the bottom of the groove of the first mounting seat 1. It is selected that a side plate 6 is installed on the side of the first slider 2, and a second threaded hole is opened on the side plate 6. A second threaded rod 7 threadedly cooperating with it is installed in the second threaded hole. The end of the second threaded rod 7 is rotatably connected to the installation strip 4. Subsequently, under the cooperation of the second threaded rod 7 and the second threaded hole of the side plate 6, the second threaded rod 7 vertically displaces in the second threaded hole, and further the bottom end of the second threaded rod 7 can be rotatably connected to the installation strip 4 to vertically displace synchronously, and finally the distance between the installation strip 4 and the bottom of the groove of the first mounting seat 1 is changed.

[0024] Regarding the above-mentioned "connection part between the second threaded rod 7 and the mounting bar 4", it is as follows: a bearing seat is fixedly connected to the mounting bar 4 and located below the second threaded rod 7, and the end of the second threaded rod 7 is fixedly connected to the center of the bearing seat. When the second threaded rod 7 rotates subsequently, it can better drive the mounting bar 4 to rise and fall. A slot is provided at the bottom of the first slider 2, and the slot is clamped in the side of the first mounting seat 1 to limit the left and right shaking of the first slider 2.

[0025] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
