Description

Waterproof column

This creation relates to a waterproof column, and in particular to a waterproof column for providing waterproof protection of electronic parts on a circuit board.

With the improvement of people's living standards, electronic products are increasingly used in life. However, electronic products are most afraid of being short-circuited by electronic components, which affects the use of electronic products and is even more susceptible to damage. Therefore, some waterproof design will be done in the electronic products, generally using coating or potting, especially designing a waterproof column applied to the circuit board, and the circuit board is equipped with a variable resistor (VARIABLE RESISTOR), in order to protect the variable The resistor will be provided with a waterproof column on the variable resistor to prevent water from seeping into the part.

Referring to the first figure, the conventional waterproof column 10 is composed of a tube body 11 combined with a plug 12, which is connected to the variable resistor 13 through one end of the tube body 11, and the other end of the tube body 11 is combined with the plug head 12. The missing of the conventional waterproof column 10 is that the plug 12 is easy to generate a gap when it is combined with the tube body 11, and moisture is easily infiltrated into the tube body 11 by the plug head 12, and the waterproof effect is not good. Moreover, the plug head 12 has no positioning design. And it is easy to loosen.

In view of this, the creator is devoted to research and design, and can provide a waterproof column with better waterproof effect, and can make the waterproof plug not easy to loosen, which is the creation of the creative research. Motivator.

The main purpose of this creation is to provide a waterproof column with better waterproof effect and to position the waterproof plug without loosening.

In order to achieve the above object, the present invention is a waterproof column, comprising: a hollow cylinder, the inner wall of the hollow cylinder is provided with a positioning portion; and a waterproof plug, the outer wall of the waterproof plug is provided with at least one waterproof ring protruding outwardly And a positioning ring; the waterproof plug is plugged into the hollow cylinder, the at least one waterproof ring is in close contact with the inner wall of the hollow cylinder, and the positioning ring is correspondingly engaged with the positioning portion of the hollow cylinder. Thereby, the waterproof effect is better, and the waterproof plug can be positioned without being loosened.

In order to further understand the features, features and technical contents of the present invention, please refer to the following detailed description of the present invention and the accompanying drawings, which are only for reference and description, and are not intended to limit the present invention.

Please refer to FIG. 2 and FIG. 3 , which are respectively an exploded perspective view and a cross-sectional view of the first embodiment of the present invention. The waterproof column 30 includes: a hollow cylinder 31 having a positioning on the inner wall of the hollow cylinder 31 . And a waterproof plug 22, the outer wall of the waterproof plug 22 is provided with at least one waterproof ring 221 and a positioning ring 222 protruding outward; the waterproof plug 22 is plugged in the hollow cylinder 31, the at least one waterproof The ring 221 is in close contact with the inner wall of the hollow cylinder 31, and the positioning ring 222 is correspondingly engaged with the positioning portion 211 of the hollow cylinder 31. The positioning portion 211 forms a stepped drop with the inner wall of the hollow cylinder 31. Thereby, the waterproof ring 221 of the waterproof column 30 closely abuts against the inner wall of the hollow cylinder 31, so that moisture does not easily penetrate into the hollow cylinder 31, so that the waterproof effect is better. As a result, the positioning ring 222 of the waterproof plug 22 is correspondingly engaged with the positioning portion of the hollow cylinder 31, so that the waterproof plug 22 is positioned and is not easily loosened.

Please refer to FIG. 4 to FIG. 6 , which are respectively an exploded perspective view, a combined perspective view and a cross-sectional view of the second embodiment of the present invention. The outer wall of the hollow cylinder 21 of the waterproof column 20 is provided with at least one step portion 212 (eg As shown in Fig. 6, there is provided a class portion 212) which is provided with at least one waterproof groove 213 which is an annular groove. Thereby, the water-proof gas is retained in the waterproof groove 213 by the waterproof groove 213 of the hollow cylinder 21, so that the waterproof column 20 has a better waterproof effect.

Please refer to FIG. 7 , which is a schematic diagram of the application of the second embodiment of the present invention, which can be assembled into an electronic product when applied, for example, when applied to the power supply casing 16 to be waterproof or glued, the The waterproof plug 22 is plugged into the hollow cylinder 21, and the hollow cylinder 21 is sleeved on the variable resistor 13 of the circuit board 14 to fill the exterior of the waterproof column 20 and pass through at least one of the waterproof plugs 22. The waterproof ring 221 (please refer to FIG. 6) and a positioning ring 222 (please refer to FIG. 6), the waterproof ring 221 of the waterproof column 20 is closely abutted against the inner wall of the hollow cylinder 21, so that moisture is not easily penetrated. The hollow cylinder 21 can have a better waterproof effect, and can effectively prevent water from directly penetrating into the variable resistor 13 of the circuit board 14. Since the variable resistor 13 actually needs to be adjusted, the resistance is adjusted. At the time of value, the waterproof plug 22 can be opened to facilitate adjustment of the resistance. Therefore, the waterproof column 20 is sleeved with the variable resistor 13 to achieve waterproofing and easy to adjust the resistance. Further, the waterproof groove 213 of the step portion 212 is an annular groove. By using the waterproof groove 213 of the hollow cylinder 21, the moisture is retained in the waterproof groove 213, so that the waterproof effect of the waterproof column 20 is enhanced.

Referring to FIG. 8, which is a cross-sectional view of a third embodiment of the present invention, a plurality of step portions 212 are disposed on an outer wall of the hollow cylinder 21 of the waterproof column 20, and each of the class portions 212 is provided with at least one waterproof groove. The groove 213, the waterproof groove 213 is an annular groove. Thereby, the water-proof gas is retained in the waterproof groove 213 by the waterproof groove 213 of the hollow cylinder 21, so that the waterproof column 20 has a better waterproof effect.

The characteristics of this creation:

1. The waterproof ring and the waterproof groove of the hollow cylinder prevent water from directly penetrating into the inner part of the hollow cylinder, and the waterproof effect is good.

2. The outer wall of the waterproof plug is provided with a positioning ring protruding outward, so that the waterproof plug is positioned and not easily loosened.

The above description is only a preferred and feasible embodiment of the present invention, and thus does not limit the scope of the patents of the present invention. The equivalent structural changes that are made by using the present specification and the contents of the drawings are all included in the scope of the present creation. , combined with Chen Ming.
