Description
Technical field
The utility model relates to memory device field, particularly relates to a kind of SD card with water-proof function.
Background technology
SD card is widely used on mancarried device, such as digital camera, personal digital assistant, multimedia player, smart mobile phone etc., SD card in current mancarried device seldom considers its waterproof effect, and be inserted with the mancarried device of SD card once accidentally intake or fall into the water, the chip of SD card is easy to into water, the data causing SD card to lose efficacy or to store in SD card is lost, thus causes irremediable consequence.
Utility model content
For solving the problems of the technologies described above; the utility model provides a kind of SD card with water-proof function; silica gel boss is enclosed at the end of the matrix of SD card and the matrix one-body molded of SD card; after making SD card insert SD draw-in groove, silica gel boss and SD draw-in groove form interference fit; thus play the effect of water proof and dust proof, protect the chip of SD card and strengthen its fail safe.
For achieving the above object, the utility model by the following technical solutions:
The utility model discloses a kind of SD card with water-proof function, the end of the matrix of described SD card is provided with a circle groove, in described groove, injection mo(u)lding has a circle silica gel boss, and wherein said silica gel boss protrudes 0.3 ~ 0.4mm than the surface of the matrix of described SD card.
Preferably, multiple excessive glue hole is also provided with in described groove.
Preferably, the spacing of overflowing between glue hole described in each is 1.5 ~ 2.0mm.
Preferably, the degree of depth of described groove is 0.3 ~ 0.4mm.
Preferably, the width of described groove is 0.5 ~ 0.6mm.
The utility model beneficial effect is compared with prior art: the method for what the utility model provided the have SD card of water-proof function, silica gel boss is enclosed at the end of the matrix of SD card and the matrix one-body molded of SD card, silica gel boss protrudes 0.3 ~ 0.4mm than the surface of the matrix of SD card, make the SD card after an one-body molded circle silica gel boss can insert SD draw-in groove easily, and silica gel boss and SD draw-in groove form interference fit, thus play the effect of water proof and dust proof, protect the chip of SD card and strengthen its fail safe; And on the matrix of SD card, be provided with a circle groove, one deck glue can also be coated with in groove before injection mo(u)lding silica gel, make the matrix of silica gel and SD card in conjunction with effective, and be not limited to the material of matrix of SD card, the material of the matrix of SD card can select plastic cement and/or metal, can also powder metallurgy be selected, can be combined closely with silica gel equally, make the product after injection moulding silica gel have the function of water proof and dust proof.
In preferred scheme, by designing excessive glue hole in a groove, when can prevent on the one hand gluing in groove, unnecessary glue can overflow the surface of glue to product, and avoid the accumulation of glue, when injection mo(u)lding silica gel, the silica gel of groove upper and lower surface can be sticked together by glue hole of overflowing by silica gel well on the other hand, be conducive to the matrix of SD card and the combination of silica gel, and strengthen the durability with the SD card of water-proof function.
Accompanying drawing explanation
Fig. 1 is the matrix schematic diagram of the SD card of the utility model preferred embodiment;
Fig. 2 is the SD card schematic diagram with water-proof function of the utility model preferred embodiment.
Embodiment
Below contrast accompanying drawing and combine preferred embodiment the utility model is described in further detail.
The SD card with water-proof function of the present utility model, the end of the matrix of SD card is provided with a circle groove, and in groove, injection mo(u)lding has a circle silica gel boss, and wherein silica gel boss protrudes 0.3 ~ 0.4mm than the surface of the matrix of SD card.
As shown in Figure 1, be the schematic diagram of matrix 11 of SD card; As can be seen from the figure the end of the matrix 11 of SD card is provided with a circle groove 111, and the width of groove is 0.5 ~ 0.6mm, and the degree of depth is 0.3 ~ 0.4mm; On groove 111, be also provided with multiple excessive glue hole 112, these excessive glue hole 112 equidistant arrangement, spacing is 1.5 ~ 2.0mm.The matrix 11 of SD card designs groove 111 and excessive glue hole 112, be very helpful to making the SD card with water-proof function, wherein, overflowing glue hole 112 can toward making the unnecessary glue in groove 111 flow out from this in groove 111 during gluing, and avoids allowing glue be deposited in and even spill in groove 111 surface of the matrix 11 of SD card.If overflow, the line space design in glue hole 112 is 1.5 ~ 2.0mm is due to the too near of glue hole 112 line space design that overflow on the one hand, the complexity of the matrix 11 of SD card can be increased, on the other hand, if overflow the too far away of glue hole 112 line space design, adhesive-spill-preventing poor effect, namely during gluing, glue is easily piled up, and has glue to overflow to the risk on matrix 11 surface of SD card.
In a specific embodiment, the width of the groove 111 of the matrix 11 of SD card is 0.5mm, length is 12.4mm, 5 excessive glue holes 112 are also offered in groove 111, be evenly distributed in groove 111, in groove 111, during cementing, can prevent glue from overflowing to the surface (matrix surface of SD card to have glue in manufacturing process) of the matrix of SD card, such painting glue is out attached to two side and the bottom surface of the groove of the matrix of SD card equably, greatly increases the yields of product; In addition, the whole circle of groove 111 all injection moulding silica gel time, the silica gel of groove upper and lower surface can be sticked together by glue hole of overflowing by silica gel, be conducive to the matrix of SD card and the combination of silica gel, and enhancing has the durability of the SD card of water-proof function.
As shown in Figure 2; it is SD card 1 schematic diagram with water-proof function; in the groove of the end of the matrix 11 of SD card, injection mo(u)lding has a circle silica gel boss 12; silica gel boss 12 protrudes 0.3 ~ 0.4mm than the surface of the matrix 11 of SD card; make the SD card 1 formed can insert SD draw-in groove easily, and silica gel boss 12 and SD draw-in groove form interference fit, thus play the effect of water proof and dust proof; wherein classification of waterproof reaches IPX7 ~ IPX8, protects the chip of SD card better and strengthens its fail safe.
The SD card with water-proof function of the present utility model, the material of the matrix of SD card can select plastic cement and/or metal, can also select powder metallurgy, can be combined closely equally with silica gel, makes the SD card after injection moulding silica gel have the function of water proof and dust proof.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; some equivalent to substitute or obvious modification can also be made, and performance or purposes identical, all should be considered as belonging to protection range of the present utility model.
