[0027] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. In order to make the purposes, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. The present application can be implemented without some of the specific details for those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0028] It should be noted that, in this paper, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0029] It should be understood that when describing the structure of a component, when one layer, one region is referred to as being located "on" or "above" another layer, another region, it can be directly located above the other layer, another region, or other layers or regions are included between it and the other layer, another region. And if the component is turned over, the layer, the region will be located "under" or "below" the other layer, another region.

[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0031] The connector body 100 in the prior art is easily displaced inside the waterproof sheath 200, resulting in poor products after glue pouring, which is specifically manifested as: after the connector body 100 is loaded into the waterproof sheath 200, before the glue is cured, axial movement occurs due to external force (such as vibration, transportation), resulting in position deviation after glue pouring, affecting the electrical contact performance or sealing effect. The present application realizes precise pre-positioning of the connector body 100 before glue pouring through the mechanical cooperation of the limiting structure 220 and the elastic sheet movable groove 110, fundamentally solving the displacement problem.

[0032] As Figure 1 and Figure 2As shown, the application proposes a waterproof connector, including a connector body 100 and a waterproof sheath 200, the connector body 100 is provided with a spring movable slot 110; the waterproof sheath 200 has a cavity 210 accommodating the connector body 100, the cavity 210 is provided with a limiting structure 220 corresponding to the spring movable slot 110, and the limiting structure 220 cooperates with the spring movable slot 110 to limit the movement of the connector body 100 in the disengagement direction.

[0033] As shown, Figure 2 As shown in one of the embodiments, the limiting structure 220 corresponds to the spring movable slot 110 on the lower surface of the connector body 100, and is arranged on the bottom wall of the cavity 210.

[0034] As shown, Figure 2 As shown in one of the embodiments, the lower surface of the connector body 100 is provided with two spring movable slots 110, and each spring movable slot 110 corresponds to a set of limiting structures 220. The two spring movable slots 110 are symmetrically distributed, cooperate with the two sets of limiting structures 220, form four-point support, uniformly disperse the weight and external force of the connector body 100, and reduce the risk of inclination or deformation.

[0035] As shown, Figure 7 As shown in one of the embodiments, each set of limiting structures 220 includes two clamping points 221, and each clamping point 221 is just clamped at the front end of the same spring movable slot 110. The two clamping points 221 are clamped into the two sides of the front end of the spring movable slot 110, form a "clamping" effect, and limit the axial (disengagement direction) movement at the same time.

[0036] As shown, Figure 2 As shown in one of the embodiments, the free end of the clamping point 221 is provided with a guide inclined surface 222. The guide inclined surface 222 at the front end of the clamping point 221 guides the connector body 100 to be smoothly loaded.

[0037] As shown, Figure 3 As shown in one of the embodiments, a glue reduction groove 230 is arranged in the waterproof sheath 200. The arrangement of the glue reduction groove 230 makes the wall thickness of the waterproof sheath 200 uniform, avoids the injection molding defects such as shrinkage and depression caused by the local wall thickness being too thick, and enhances the overall rigidity and anti-deformation ability of the sheath.

[0038] As shown, Figure 3 As shown in one of the embodiments, the two sides of the cavity 210 are respectively provided with a protruding rib 240 extending along the length direction, and the protruding rib 240 is used for preventing the left and right deviation when the connector body 100 is loaded into the cavity 210 of the waterproof sheath 200. The protruding rib 240 extends along the length direction of the cavity 210, cooperates with the gap between the two sides of the connector body 100, forms a physical guide rail, forces the connector body 100 to move linearly along the axial direction, and avoids the left and right skew.

[0039] As Figure 2 shown, in one embodiment, the connector body 100 and the waterproof sheath 200 are positioned by the limiting structure 220 and the spring-leaf movable slot 110, then the gap between the two is filled with epoxy resin glue 300, and the epoxy resin glue 300 forms a sealing layer after curing to achieve waterproof sealing and fixed connection. The mechanical clamping (providing initial positioning) of the limiting structure 220 and the spring-leaf movable slot 110 and the adhesive force of the epoxy resin glue 300 (forming rigid connection after curing) work together to form double fixation.

[0040] The assembly process of the connector body 100 and the waterproof sheath 200 in the embodiment is as follows:

[0041] The manufactured connector body 100 is aligned with the opening of the cavity 210 of the waterproof sheath 200, and under the guidance of the convex ribs 240 on both sides of the cavity 210, the connector body 100 is smoothly inserted into the cavity 210 of the waterproof sheath 200.

[0042] When the spring-leaf movable slot 110 on the lower surface of the connector body 100 approaches the limiting structure 220 (clamping point 221) of the bottom wall of the cavity 210, the guide slope 222 of the free end of the clamping point 221 begins to work, guiding the clamping point 221 to smoothly clamp into the front end of the spring-leaf movable slot 110, achieving the pre-positioning of the connector body 100 in the waterproof sheath 200 and preventing it from moving in the disengagement direction.

[0043] After the connector body 100 and the waterproof sheath 200 are positioned by the limiting structure 220 and the spring-leaf movable slot 110, the epoxy resin glue 300 is injected into the gap between the two using a glue injection device to ensure that the glue uniformly fills each gap. The assembly filled with glue is placed in a suitable environment, and the epoxy resin glue 300 is cured under certain temperature and humidity conditions to form a sealing layer.
