This electronic product 10 includes casing 1 and waterproof button 2, be formed with at least one key hole 11 on the casing 1, every key hole 11 need correspond waterproof button 2 of installation, waterproof button 2 needs to realize circuit connection with the inside structure of electronic product 10 when using, in order to protect the normal use of electronic product 10 inner structure and electronic product, waterproof button 2 and the cooperation of key hole 11 of here need realize sealed water-proof effects. It should be understood that fig. 1 only shows the structure of the casing 1 and the waterproof button 2, and the electronic product 10 has other structures (such as an electronic product main board located in the casing 1, etc.), which are not shown here.
For the specific structure of the key hole 11, refer to a partial structure diagram of a key hole 11 on the casing 1 shown in fig. 2 and a top view of a key hole 11 on the casing 1 shown in fig. 3. As shown in fig. 2 and fig. 3, the key hole 11 is equivalent to a counter bore formed by sinking on the casing 1, and an opening 111 is formed at the bottom of the counter bore, where the opening 111 penetrates through the casing 1 to communicate with a built-in key of the electronic product 10 located in the casing 1; an annular groove a is formed in the key hole 11 around the opening 111, and the annular groove a is formed between the annular retaining wall 112 and the inner wall of the key hole 11. It should be understood that the shape of the key hole 11 is rectangular with arc-shaped chamfers, and the opening 111 is circular, which are only examples, and in the specific implementation, the shape may be appropriately modified according to the specification, shape and space of the product, for example, the opening 111 may be square, and the key hole 11 may be circular.
The key hole 11 is cut by a cutting plane a-a shown in fig. 3 to obtain a schematic sectional structure shown in fig. 4, and the structure of each part in the key hole 11 can be clearly seen from fig. 4; wherein, the annular groove S is formed between the annular retaining wall 112 and the inner wall of the key hole 11, and the top end of the annular retaining wall 112 is lower than the surface of the casing 1; the opening 111 extends downward from the annular wall 112 to penetrate through the casing 1, an annular projection 1111 is further formed inside the opening 111, and along the extending direction of the opening 111, the annular projection 1111 forms an inclined plane B towards one side of the annular groove S (i.e. the side where the annular wall 112 is disposed).
Please refer to fig. 5 to 7a for a structure of the waterproof button 2 matching the button hole 11 shown in fig. 2 to 4. Fig. 5 is a schematic perspective view of the waterproof button 2, and fig. 6 is a top view of the waterproof button 2; the waterproof key 2 comprises a base 21, wherein a conductive base 22 and an annular retaining ring 23 surrounding the conductive base 22 are convexly formed on one side (the side, which is upward from the base 21, shown in fig. 5) of the base 21, and the annular retaining ring 23 is equivalent to the edge formed on the base 21; of course, this is merely an example of a structure, and the annular retainer ring 23 may also be disposed inside the edge of the base 21, which is not illustrated here.
With reference to fig. 5 and fig. 6, since the waterproof key 2 is used to match the key hole 11 shown in fig. 2 to fig. 4, when the waterproof key 2 is installed in the key hole 11 in a matching manner, the annular retaining ring 23 may be in interference fit with the annular groove S in the key hole 11, the inner wall of the annular retaining ring 23 will abut against the outer wall of the annular retaining wall 112, and the outer wall of the annular retaining ring 23 will abut against the inner wall of the key hole 11.
It should be noted that the waterproof key 2 herein is made of a soft rubber material, such as thermoplastic polyurethane elastomer rubber or other materials, and when the waterproof key 2 is installed in the key hole 11 in a matching manner, the waterproof key 2 has a larger deformation space and can obtain a tight interference fit effect, thereby improving the waterproof effect.
And the conducting base 22 of the waterproof key 2 is used for stretching into the opening 111 of the key hole 11 to match with the built-in key, based on the structure of the key hole 11, a plug tail buckle 221 is further formed at the end part of the conducting base 22 far away from the base 21, and the plug tail buckle 221 can be clamped with the annular boss 1111 in the opening 111 to prevent the waterproof key 2 from falling off from the key hole 11. Here, the plug tail clip 221 is shown as an annular ridge that surrounds the conductive base 22.
In addition, as shown in fig. 5 and fig. 6, the base 21 is further formed with a supporting boss 24 around the conductive base 22, the supporting boss 24 can play a certain consolidation role for the conductive base 22, and meanwhile, when the waterproof key 2 is detached from the key hole 11, the connecting force between the conductive base 22 and the base 21 is increased, and the conductive base 22 is prevented from being damaged due to the clamping effect of the annular boss 1111.
The key hole 11 is cut by the cutting plane C-C shown in fig. 6 to obtain the schematic sectional structure shown in fig. 7a, and it can be seen that the cross section of the supporting boss 24 may be in the shape of a right trapezoid, and the right angle side of the right trapezoid is close to the conductive base 22 to provide a good support for the conductive base 22; alternatively, as shown in fig. 7b, the cross-section of the support boss 24 may be shaped as a right triangle, and of course, the right side of the right triangle also grips the conductive base 22. It should be noted that the structure in fig. 7b is only a simple example.
Referring to fig. 7a, the plug tail clip 221 is shown as an annular rib, wherein a side of the annular rib facing the base 21 forms a step with the conductive base 22, and a side of the annular rib away from the base 21 forms an inclined surface with the conductive base 22.
When the waterproof key 2 is installed in the key hole 11 of the casing 1, the structure of the waterproof key 2 and the key hole 11 is shown in fig. 8; it can be seen that the annular retaining ring 23 of the waterproof key 2 is in interference fit with the annular groove S of the key hole 11, the inner wall of the annular retaining ring 23 abuts against the outer wall of the annular retaining wall 112, and the outer wall of the annular retaining ring 23 abuts against the inner wall of the key hole 11, which is equivalent to forming two waterproof structures; the conductive base 22 passes through the opening 111 of the key hole 11 to be in butt joint fit with the built-in case 3 in the case 1, and an inclined plane B is formed on one side of the annular boss 1111 facing the annular retaining wall 112, so that the conductive base 22 can conveniently pass through the opening 111 from outside to inside; the tail-plugging buckle 221 on the conductive base 22 is clamped at the lower side of the annular boss 1111 in the opening 111, so that the waterproof key 2 can be prevented from falling off from the key hole 11.
To sum up, in the electronic product 10 provided by the embodiment of the present invention, the waterproof button 2 can be installed in the button hole 11 of the casing 1 from outside to inside in a fitting manner, and the waterproof button 2 and the annular groove S in the button hole 11 form two waterproof structures in an interference fit manner, so as to achieve a good waterproof effect; and, the waterproof button 2 cooperates simple structure, convenient dismantlement of key hole 11, and the processing cost is lower, is favorable to the production popularization.
