Description
Technical field
The present invention relates to the casing joint structure of a kind of casing joint structure, particularly a kind of electronic installation.
Background technology
People use electronic installation miscellaneous through regular meeting in daily life, for example power-supply adapter, transformer, power supply unit and power connector etc.Therefore these electronic installations all can utilize housing that these electronic building bricks and circuit are coated owing to electronic building brick on its internal circuit carrier and circuit need be done suitable isolation and protection, contact to avoid direct and extraneous.Because casing joint structure design and juncture can have influence on outward appearance, structural strength and the electrical characteristic of electronic installation, the casing joint structure that therefore how to design suitable electronic installation just becomes considerable research and development problem.
See also Fig. 1, it is for showing the casing joint structure schematic diagram of traditional electronic devices.As shown in Figure 1, the casing joint structure of traditional electronic devices mainly comprises upper shell 1 and lower house 2, wherein upper shell 1 is all box body structure with lower house 2, and upper shell 1 has junction surface 11, lower house 2 has corresponding engagement portion 21, be bonded with each other by the junction surface 11 of upper shell 1 and the junction surface 21 of lower house 2, can make upper shell 1 and lower house 2 finish combination.
See also Fig. 2, it is the structure enlarged drawing at the junction surface of upper and lower casing in the structure shown in Figure 1.As shown in Figure 2, the junction surface 11 of upper shell 1 forms first protuberance 112, first groove 113 and second protuberance 114 in regular turn from its lateral surface 110 to medial surface 111 directions.In addition, the junction surface 21 of lower house 2 forms first recess 212, first protuberance 213 and second recess 214 in regular turn from its lateral surface 210 to medial surface 211 directions, and first protuberance 112, first groove 113 with junction surface 11 is relative with second protuberance 114 respectively.In addition, has a fin 215 on first protuberance 213 at junction surface 21, and the width of first protuberance 213 at junction surface 21 is slightly less than the width of first groove 113 at junction surface 11, when upper shell 1 engaged with lower house 2, first protuberance 213 at junction surface 21 just can be placed in first groove 113 at junction surface 11 thus.
See also Fig. 3 (a)～3 (b), it is the schematic diagram of the juncture of demonstration structure shown in Figure 2.Shown in Fig. 3 (a), when desiring to carry out the housing joint, at first with first protuberance 112 at the junction surface 11 of upper shell 1, first groove 113 and second protuberance 114 respectively with first recess 212 at the junction surface 21 of lower house 2, first protuberance 213 is relative with second recess 214, utilize the ultrasonic waves fusion techniques then, directly on housing, produce the sound wave vibrations of ultra-high frequency by the soldering tip (Horn) of ultrasonic waves plastically welding machine, make, lower house 1,2 produce violent friction each other after, make fin 215 on first protuberance 213 at junction surface 21 fuse into the inwall of first groove 113 at junction surface 11 in moment, shown in Fig. 3 (b), thus with on reaching, lower house 1,2 purposes that engage.
Yet, in traditional casing joint structure, after upper and lower casing 1,2 engaged, 11,21 the formed electric creepage distances in its junction surface still fell short of comparatively speaking, therefore the situation that has electric electric leakage produces, and affects indirectly the electrical characteristic of electronic installation.In addition, upper shell 1 is not good with the bond strength of lower house 2, it is lower to make electronic installation bear the ability of external force collision, and therefore the junction surface 11 that need increase upper shell 1 for head it off usually simultaneously and the thickness at the junction surface 21 of lower house 2 can increase material cost to for example more than about 3mm.In addition, in traditional casing joint structure in order to increase electric creepage distance, second protuberance, 114 length at the junction surface 11 of upper shell 1 can't reduce, so when external force when clashing into perpendicular to the direction of junction surface 11,21 lateral surfaces, second protuberance 114 causes upper shell 1 to separate with lower house 2 easily because of fragile structure ruptures even destroy casing joint structure.
Therefore, how to avoid the disappearance of above-mentioned known technology, and develop a kind of casing joint structure that can after shell combination, increase the electronic installation of electric creepage distance and reinforcement housing bond strength, real in pressing for the problem of solution at present.
Summary of the invention
Main purpose of the present invention can increase electric creepage distance and improve the housing bond strength for a kind of casing joint structure of electronic installation is provided after shell combination, thus to increase the structural strength and the electrical characteristic of electronic installation.
