[0024] The present invention will be further described in detail below with reference to specific embodiments:

[0025] like Figure 1 As shown, the connector socket housing structure includes a main housing 2, the internal space of which is divided into several sub-chambers 3 by a partition 1, combined with an attached... Figure 2 As shown, each sub-chamber 3 is provided with a limiting ring 5, which is integrally connected with the inner wall of the main housing 2 and the side wall of the partition plate 1 to form a limiting solid structure. The mounting hole 4, sub-chamber 3, limiting ring 5, and partition plate 1 are all in the same length direction as the main housing 2. The terminal 8 is assembled inside the main housing 2 along the mounting hole 4 and is limited and fixed by the limiting ring 5.

[0026] Specifically, as shown in the attached document Figure 3 As shown, the partition plate 1 includes a base 13, a first extension 11 and a second extension 12. The base 13 is disposed inside the main housing 2 and is integrally connected with the limiting ring 5, thereby increasing the strength of the main housing 2 and making it less prone to deformation.

[0027] In the direction extending vertically from the main housing 2, reference platforms 6 are formed on both end faces of the limiting ring 5, and the reference platforms 6 are parallel to the two end faces of the base 13. A boss ring 7 is provided around the mounting hole 4 on the surface of the reference platform 6. The boss ring 7 limits the assembly of the terminal 8, preventing the terminal from moving back and forth and improving the stability of the terminal assembly.

[0028] The first extension 11 and the second extension 12 are disposed at both ends of the base 13 and extend distally along the length of the main housing 2, respectively. (See attached diagram.) Figure 4 As shown, when the terminal 8 is assembled in the main housing 2, due to the spacing between the first extension 11 and the second extension 12, there is a larger creepage distance between adjacent terminals 8, and the extension length of the first extension 11 and the second extension 12 is positively correlated with the size of the creepage distance between the terminals.

[0029] Within the length range of the main housing 2, the lengths of the first extension 11 and the second extension 12 are maximized to increase the creepage distance. For example, in one embodiment or other embodiments, the sum of the lengths of the first extension 11, the second extension 12, and the base 13 along the same straight line along the extension direction of the main housing 2 is not less than two-thirds of the length of the terminal 8.

[0030] Even if leakage occurs, the current is more easily blocked by the insulating material spacer 1 and will not directly contact the low potential area. The longer creepage distance means that the connector has higher electrical safety performance.

[0031] In detail, the first extension part 11 is on the same side of one end of the terminal 8, and the length of the first extension part 11 is greater than the length of the second extension part 12, thereby improving the safety of the terminal insertion end. The first extension part 11 and the second extension part 12 can be configured in any shape in the terminal assembly direction to increase the creepage distance.

[0032] In one embodiment or other embodiments, reference is made to the accompanying Figure 4 The spacer plate 1 comprises a base 13, and a pair of first extension parts 11 and second extension parts 12 are arranged at two ends of the base 13, and the first extension part 11 is on the same side of the terminal 8 insertion end.

[0033] In the second embodiment or other embodiments, as shown in the accompanying Figure 5 Two first extension parts 11 or second extension parts 12 are arranged side by side on the same side of the base 13, the first extension part 11 is on the same side, and the second extension part 12 is on the other same side end. A groove structure is formed between adjacent first extension parts 11 or adjacent second extension parts 12, which plays a guiding role when connecting the terminal 8 to the opposite terminal, and the "interlocking" connection mode is more stable.

[0034] In the third embodiment or other embodiments, reference is made to the accompanying Figure 6 Two first extension parts 11 or second extension parts 12 are arranged side by side on the same side of the base 13, and the lengths of the first extension part 11 and the second extension part 12 on the same side are inconsistent, so that the base 13 becomes a special-shaped structure, and the staggered height difference effect increases the creepage distance.

[0035] The utility model belongs to the field of electric connector, and relates to connector socket shell structure, realizes copper piece and electric connector shell fixed, and terminal opposite connection is applied to unmanned plane, AI robot and other fields. Through setting up spacer plate, the strength of main shell is increased, and deformation is not easy, and the creepage distance between terminals can be increased, so that the electrical performance is more safe and stable.

[0036] The above-mentioned embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model. For those skilled in the art, obviously, the utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model, therefore, no matter from which point, the embodiments should be regarded as exemplary and non-limiting, and the scope of the utility model is defined by the appended claims instead of the above-mentioned description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
