Example 1

The utility model provides a waterproof test stopper that surface coating has sealing material, as shown in fig. 1-5, including stopper main part 1, the centre of stopper main part 1 is equipped with counter bore 10, stopper main part 1 includes top stopper 11, is equipped with end stopper 12 under top stopper 11, is equipped with a plurality of excessive cock bodies 13 between end stopper 12 and the top stopper 11 regularly, reduces in proper order from the external diameter of a plurality of excessive cock bodies 13 that distribute down, is equipped with center post 2 in the counter bore 10, evenly scribbles on the side outer wall of stopper main part 1 and is equipped with sealing coating 3.

In this embodiment, integrated into one piece has spacing collar 111 on the top lateral wall of top stopper 11, and the external diameter of spacing collar 111 is greater than the external diameter of top stopper 11, makes spacing collar 111 durable firm, difficult fracture or drop, avoids stopper main part 1 to plug in the jack of electronic equipment in through spacing collar 111 and is difficult to extract completely.

In this embodiment, the top plug 11, the bottom plug 12 and the plurality of excessive plug bodies 13 are integrally formed, and the number of the excessive plug bodies 13 is at least one, so that the plug body 1 has a compact and stable overall structure, high density and good sealing performance.

Specifically, the plug main body 1 is made of high-quality latex, is soft and elastic in material, wear-resistant and durable, good in sealing performance and insulating, and improves safety in the testing process of electronic equipment.

In this embodiment, the heights of the plurality of excessive plugs 13 are equal, the outer side wall of the excessive plug 13 is in a semicircular arc shape, so that the excessive plug 13 has a uniform structure and the outer side wall is smooth and flat, and when the size of the jack is smaller than the outer diameter of the bottom plug 12 and larger than the outer diameter of the top plug 11, the outer side of at least one excessive plug 13 can be tightly plugged into the jack after being deformed due to stress, so that the jack can be plugged.

Further, the height of the transition plug body 13 is smaller than that of the top plug 11, the height of the transition plug body 13 is smaller than that of the bottom plug 12, and when the aperture of the jack is equal to the outer diameter of the top plug 11 or the bottom plug 12, the top plug 11 or the bottom plug 12 can completely block the jack; when the aperture value of the jack is between the outer diameter values of the top plug 11 and the bottom plug 12, the small-height excessive plug body 13 is more prone to stress deformation and is plugged into the jack, and the situation that the elasticity of the excessive plug body 13 is affected due to the fact that the height of the excessive plug body is too large is avoided.

Specifically, the outer diameter of the topmost transition plug body 13 is smaller than or equal to the outer diameter of the top plug 11, and the outer diameter of the bottommost transition plug body 13 is larger than or equal to the outer diameter of the bottom plug 12, so that the top plug 11 can be more uniformly and finely transited to the bottom plug 12.

In this embodiment, the counter bore 10 sequentially penetrates through the top plug 11 and the plurality of excessive plug bodies 13 and then extends into the bottom plug 12, so that the middles of the top plug 11, the bottom plug 12 and the plurality of excessive plug bodies 13 can be in contact with the central column 2 to some extent, the firmness of each layer of plug bodies is increased through the central column 2, and the deformation degree of each layer of plug bodies is reduced.

Further, the depth of the counter bore 10 is smaller than the height of the plug main body 1, so that the central column 2 is prevented from penetrating through the whole plug main body 1, and the phenomenon of water leakage at the joint between the central column 2 and the plug main body 1 is avoided.

In this embodiment, the central column 2 includes a column 21, the diameter of the column 21 is equal to the bore diameter of the counterbore 10, and the height of the column 21 is greater than or equal to the depth of the counterbore 10, so as to avoid the situation that the column 21 is completely inserted into the plug body 1, which may cause excessive deformation of the top end of the plug 11.

Further, the cylinder 21 is in clamping fit with the counterbore 10, and the inner side wall of the counterbore 10 is fused and fixed on the outer side wall of the cylinder 21, so that the cylinder 21 is tightly and stably connected with the plug main body 1 and is not easy to fall off.

Furthermore, a pull ring 22 is welded and fixed at the top end of the cylinder 21, and the plug body 1 can be easily plugged into or pulled out of the jack by pinching the pull ring 22; if the plug body 1 is lost, the plug body 1 can be tied to an electronic device by using the pull ring 22 with a string.

Specifically, center post 2 adopts high-quality aluminum alloy to make, and its material is light pleasing to the eye, hard firm, the performance is firm, non-deformable, can effectively avoid stopper main part 1 to receive external force excessive deformation, probably influences its leakproofness.

In this embodiment, seal coat 3 passes through the glue adhesion to be fixed on the side outer wall of stopper main part 1, makes seal coat 3 firm, be difficult for droing.

Specifically, the sealing coating 3 that involves in this embodiment can adopt the polyurethane that the production of the confession water gentamics rubber and plastic goods limited provided to meet water inflation stagnant water glue, and its material viscidity is good, the stable performance meets water inflation, has good dual sealing stagnant water function, has further improved the waterproof nature and the leakproofness of test stopper.

The waterproof test stopper that the surface coating of this embodiment has sealing material is when using, at first take the electronic equipment that awaits measuring, and take rather than jack size assorted test stopper, hold between the fingers pull ring 22 on center post 2 top and closely plug stopper main part 1 in the jack, plug into the in-process of jack with stopper main part 1, still can rotate pull ring 22 gently, make the inside wall fully contact chucking of side outer wall of stopper main part 1 and jack, then carry out waterproof test to electronic equipment according to conventional flow can, in the test process, if carelessly there is a little water when overflowing between stopper main part 1 and the jack, sealing coating 3 meets water inflation, further block up the gap between stopper main part 1 and the jack, avoid the further infiltration of the water yield, improve waterproof test's success rate, improve the accuracy of test result.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
