[0002] Some existing connectors do not have waterproof and dustproof functions, or use relatively complex inner and outer mold structures to achieve waterproof and dustproof functions. However, with the development and progress of current technology, increasingly fierce competition, and downstream manufacturers and consumers putting forward higher requirements for products, waterproof and dustproof functions are necessary. The traditional means is to design inner and outer molds to achieve such functions.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or components / elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] Figure 1 It is a three-dimensional diagram of a perforated anti-condensation sheath provided by an embodiment of the utility model; Figure 2 1 is a three-view diagram of a perforated anti-condensation sheath provided by an embodiment of the utility model, wherein Figure 2 (a) is the front view, Figure 2 (b) is the left view, 2(c) is the top view; Figure 3 FIG. 1 is a schematic diagram of the assembly of a perforated anti-condensation sheath provided by an embodiment of the utility model. Figure 1-3 As shown, the perforated anti-condensation sheath comprises: a soft rubber sheath 1, a front section assembly port 2 connected to one end of the soft rubber sheath 1, a threading hole 3 connected to the other end of the soft rubber sheath 1, and a wire harness anti-slip tongue 4 connected to the threading hole 3; wherein the soft rubber sheath 1, the front section assembly port 2, the threading hole 3 and the wire harness anti-slip tongue 4 are integrally formed.

[0020] Specifically, the material of the soft rubber sheath 1 can be rubber, specifically, oil-exhausted EPDM 60A rubber; the use environment of this material is -40~120℃, the rubber with tensile strength ≥10MPa and elongation at break of 600-900% is placed in an aging box with an ozone concentration of 80±5pphm and a constant temperature of 40±2° for 24 hours and then taken out without cracking. It should be noted that the elongation at break of the soft rubber / rubber needs to meet the requirements so that the material can be expanded by 4 times to prevent the threading hole 3 from breaking.

[0021] The method of using the perforated anti-condensation sheath of the present application is: after the wiring harness and the circuit board of the connector are welded, the perforated anti-condensation sheath is inserted from one end of the connector to cover the entire circuit board and expose the connector; before inserting, the threading hole 3 needs to be opened, and after inserting, the sheath naturally shrinks due to the elasticity of the rubber, thereby covering the circuit board; when the threading hole 3 is opened, it can be enlarged by an expander.

[0022] In addition, the wire harness anti-slip tongue piece 4 is used to wrap it with tape so that it is covered together with the wire material, thereby preventing the sheath from slipping out.

[0023] According to the perforated anti-condensation sheath of the utility model, the sheath of soft glue or rubber makes it possible for a variable connector structure to use one sheath to achieve the functions of dustproof, waterproof and anti-condensation. The sheath has a simple structure, straight-through assembly, and convenient installation, which reduces the assembly time and can reduce production and R&D costs.

[0024] According to an embodiment of the utility model, an anti-skid boss 5 is provided at the threading hole 3 , and the anti-skid boss 5 is integrally formed with the soft rubber sheath 1 .

[0025] According to an embodiment of the present utility model, a second anti-slip boss 6 is provided at the outer end of the wire harness anti-slip tongue piece 4 , and the second anti-slip boss 6 is integrally formed with the anti-slip tongue piece 4 .

[0026] Specifically, the anti-skid boss 5 and the second anti-skid boss 6 are used to prevent the adhesive tape from slipping out after being wrapped.

[0027] According to an embodiment of the utility model, the soft rubber sheath 1 is in the shape of a trapezoidal platform; the wide end of the trapezoidal platform is connected to the front section assembly opening 2, and the narrow end is connected to the threading hole 3.

[0028] According to an embodiment of the present utility model, the front assembly opening 2 is rectangular, and the threading hole 3 is circular.

[0029] Specifically, the current mainstream connector is rectangular and the wiring harness is circular. The sheath is designed to have a corresponding shape so that it can fit tightly and ensure reliable waterproof and dustproof properties.

[0030] The above embodiments are preferred implementation schemes of the present application. In addition, the present application may also be implemented in other ways. Any obvious replacement without departing from the concept of the present application is within the protection scope of the present application.
