Description
Technical field
The utility model relates to a kind of annex of electronic equipment, is meant a kind of sealing flexible glue plug that is used on the electronic equipment expansion mouth especially.
Background technology
Modern electronic product all develops towards direction more and more lighter, thin, short, that be convenient for carrying, has become instrument important in people's daily life like portable products such as mobile phone, cameras.Mobile phone, camera or the like electronic product often is carried into outdoor use by people; And out of doors in the activity; Unavoidably be in the husky adverse circumstances of high humidity or many dirt, so the sealing of this electronic product and waterproof ability are for guaranteeing that safety of products turns round and the life-span just seems most important.
The husky approach that gets into electronic product of moisture and dirt generally has two kinds: a kind of is that because the shell of electronic equipment is to be formed by a plurality of component compositions, the formed slit of the joint of each member can become the approach that moisture and dust infiltrate; Another kind, owing on the housing of electronic equipment, need offer expansion interface, for connecting power supply or external equipment, these expansion interfaces also are the infiltration approach of moisture and dust.
Being the problem of the housing gap sealing that solves electronic equipment, generally is through strengthening the engaging force between each member, and it is tightr to make that joint cooperates, and filling with sealant, sealing gasket or the like prevent that further moisture, dust from getting at place, housing slit.Yet this waterproof construction is to belong to semi-permanent waterproof, is under the situation that the housing of electronic equipment can't be disassembled arbitrarily, to keep fire resistance characteristic.
Because the expansion interface of offering on the housing of electronic equipment also is one of route of entry of dust and moisture; Therefore when the expansion interface place can't waterproof; Aforesaid housing gap sealing is just meaningless, so the sealing at expansion interface place is most important for the sealing of complete machine.Through in expansion mouthful, being provided with and realizing by easy-to-dismount sealing flexible glue plug, seal expansion interface to the sealing at expansion interface place, and can when needs use the expansion mouth, will seal the flexible glue plug and take off by sealing flexible glue plug.
Like Fig. 1, shown in 2; Be existing sealing flexible glue plug, it comprises the cock body that is complementary with expansion interface, for preventing because of the little problem of losing easily of cock body volume; People have been wholely set intercell connector on cock body, with intercell connector with screw fixings around corresponding expansion interface on the shell body.The above-mentioned this mode that intercell connector is set on cock body not only can prevent that effectively moisture, dust from getting into electronic equipment internal through expansion interface and corroding electronic devices and components by cock body; Can also utilize the intercell connector that is arranged on the cock body a kind of mode of operation easily to be provided to people; Do not worry that plug loses, therefore by widespread on the expansion interface of some mobile electronic devices.Water door like number of patent application 200910110093.2 disclosed a kind of portable electric appts is a kind of representative prior art.Yet existing this sealing flexible glue plug is when cooperating with expansion interface, and sealing flexible glue intercell connector and the syndeton between the expansion interface beyond the Great Wall still exists a series of technological deficiency, as:
At first; Be connected fastening between the intercell connector of sealing flexible glue plug and the shell body through screw; This connected mode is cumbersome when mounted, wastes time and energy, and when screw pin is connected in intercell connector and the corresponding connecting hole of shell body; Can't judge between intercell connector and the shell body whether be locking state from the front of screw; Continue under the locking state to tighten the connecting hole explosion that screw makes shell body easily if be in,, and can't realize good waterproof effect if the non-locking state of screw can make between two parts seal bad again;
Secondly; Because said intercell connector be and the integrated flexible glue bar of said cock body, so utilize screw with its pin joint on shell body the time, need tighten the intercell connector that screw makes ailhead process for the flexible glue bar and apply the precompressed amount; Play the effect of sealing gasket; Thereby realize the sealing thread hole, yet the precompressed amount that screw applies said intercell connector has determined the seal degree of screwed hole, that is to say; If the precompressed quantity not sufficient that screw applies said intercell connector; The sealing leak just easily appears in the connecting hole between said intercell connector and the shell body, and said cock body also can pull intercell connector and make it that deformation take place in dismounting, when installing, thereby influences the sealing property of said connection screw thread hole;
At last,, influence the attractive in appearance of complete machine, and metallic screw can make the inside and outside conducting of housing of equipment, the antistatic effect of reduction complete machine because the screw long term exposure in air, is easy to corrosion.
More than be the existing in the specific implementation major technique defective of conditional electronic equipment waterproof sealing method of testing, be the utility model the subject matter that will research and solve.
