[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0022] It should be noted that in the embodiments of the utility model, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0023] In addition, the description of 'first','second' and the like in the embodiments of the utility model is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features.

[0024] The utility model embodiment provides a kind of cable SR waterproof structure of severe environment high temperature resistance, can protect cable, and this SR waterproof structure is simple and reliable, reduces the structure of waterproof in the interior, to reduce the structure of injection mold in the process of carrying out SR structure injection processing, so that production cost is reduced, and, avoid again processing waterproof silica gel.

[0025] Specifically, as shown in Figures 1-6 The utility model embodiment provides a kind of cable SR waterproof structure of severe environment high temperature resistance, including a wire harness 100, further including a SR body 200 and waterproof glue 300 for waterproof setting, specifically, SR body 200 is installed on wire harness 100, and first end 201 and second end 202 are provided along axis, first end 201 is provided with glue injection groove 210 along its thickness, the width size of glue injection groove 210 is greater than the linear size of wire harness 100, so that the both ends of glue injection groove 210 form glue injection through hole 211 on the both sides of wire harness 100, one end of glue injection groove 210 is provided with opening structure towards surrounding expansion, so that the upper end opening position of glue injection groove 210 forms descending step, waterproof glue 300 is injected along glue injection through hole 211, and the upper surface of waterproof glue 300 is located within the height range of descending step.

[0026] In the embodiment, the SR body 200 is injection molded on the wire harness 100 by injection molding processing. The first end 201 of the SR body 200 in the embodiment is provided with a glue injection groove 210, and the width of the glue injection groove 210 is greater than the diameter of the wire harness 100, so that the glue injection groove 210 is provided with glue injection through holes 211 penetrating the thickness of the second end 202 at both ends of the wire harness 100. The waterproof glue 300 is injected into the glue injection groove 210 through the two glue injection through holes 211, and the waterproof effect between the SR structure and the wire harness 100 is achieved after solidification. At this time, as shown in Figures 4-5 the opening structure of the glue injection groove 210 at one end is outwardly expanded, so that the opening of the glue injection groove 210 is formed with a descending step. When the waterproof glue 300 is injected, the upper surface of the waterproof glue 300 is within the height range of the descending step, so that the waterproof effect of the glue 300 can be avoided to be poor due to too little glue, and the appearance of the product can also be affected due to too much waterproof glue 300 injected into the glue injection groove 210.
