The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a contact connector for a DC power distribution drawer, such as Figure 1-4 As shown, it includes a plug 1 and a socket 2, the plug 1 is located on one side of the socket 2, and a mounting plate 3 is integrally formed at the central position of the outer wall of one side of the plug 1, a guide block 4 is integrally formed on the outer wall of one side of the plug 1 adjacent to the mounting plate 3, and a contact 5 is arranged on the outer wall of the other side of the plug 1, a plug-in platform 6 is arranged at the central position of the inner wall of one side of the socket 2, a contact hole 7 is opened on the outer wall of one side of the plug-in platform 6, the contact 5 and the contact hole 7 match and fit with each other, and a miniature gas spring 8 is fixedly connected to the inner wall of the side of the socket 2 adjacent to the plug-in platform 6 by screws, and a total of sixteen miniature gas springs 8 are arranged, and the sixteen miniature gas springs 8 are symmetrically arranged on the inner wall of the socket 2 in groups of four, a limiting plate 9 is arranged at one end of the miniature gas spring 8, a guide plate 10 is integrally formed on the outer wall of one side of the limiting plate 9, and a guide cover 11 is arranged on the outer wall of one side of the limiting plate 9 adjacent to the guide plate 10, and a DC distribution drawer 12 is fixedly connected to the outer wall of one side of the mounting plate 3 by bolts.

[0022] It should be noted that, since the existing DC distribution drawers are prone to connectors colliding with the cabinet sheet metal parts and causing damage, thus posing a safety hazard, this embodiment guides the plug 1 inserted into the socket 2 through the limit plate 9 and the guide plate 10, so that the plug 1 is gradually guided to the middle position during insertion, thereby reducing the friction during contact, thereby preventing the DC distribution drawer 12 from shaking left and right when pushed in with force, causing misalignment and damage due to impact, and the guide cover 11 is used to limit the guide block 4 to ensure a certain degree of firmness after insertion, thereby preventing the plug 1 and the socket 2 from loosening after insertion.

[0023] Specifically, in this embodiment, this scheme mainly includes a plug 1 and a socket 2. When in use, the mounting plate 3 is fixedly installed on the outer wall of the DC distribution drawer 12, and the socket 2 is installed on the inner side of the switch cabinet, so that when the DC distribution drawer 12 is inserted into the switch cabinet, the plug 1 and the socket 2 can be plugged in. When the plugging operation is performed, the DC distribution drawer 12 is pushed to move, and the plug 1 on the DC distribution drawer 12 moves synchronously. The plug 1 contacts the guide plate 10. Due to the inclination of the guide plate 10 and under the limiting guidance of the micro gas spring 8, the guide plate 10 drives the limiting plate 9 to move in the vertical direction after being subjected to the horizontal extrusion force, and the four limiting plates 9 are expanded. At this time, the plug 1 can be fully inserted between the four limiting plates 9. After limiting, the guide block 4 is embedded in the guide cover 11 to complete the positioning of the plug 1 after being inserted into the socket 2, and to ensure that the plug-in has a certain firmness. The contact 5 is inserted into the contact hole 7 on the plugging platform 6 to realize the plug-in of the plug 1 and the socket 2.

[0024] In a further preferred embodiment of the present invention, Figure 1-4 As shown, one side end of the guide block 4 is provided with a round chamfer, and the other side end of the guide block 4 is provided with an inclined surface, the cross-section of the guide cover 11 is an arc-shaped structure, and a rectangular through groove is opened on the outer wall of one side of the limit plate 9 near the guide cover 11.

[0025] In this embodiment, the inclined surface on the guide block 4 can reduce the contact area between the guide block 4 and the guide plate 10, reduce resistance, and the chamfered guide block 4 can be embedded in the guide cover 11 to complete the positioning of the plug 1 after being inserted into the socket 2, and ensure that the plug-in has a certain firmness.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the cross section of the plug 1 is a "cross" shaped structure.

[0027] In this embodiment, four guide blocks 4 may be provided to guide the plug 1 in the horizontal and vertical directions when it is inserted.

[0028] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the angle between the limiting plate 9 and the guide plate 10 is 150 degrees.

[0029] In this embodiment, the inclined guide plate 10 can be used to guide the plug 1 during insertion.
