Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.
It should be noted that the terms of orientation such as left, right, up, down, etc. in the present embodiment are only relative concepts or reference to the normal use state of the product, and should not be considered as limiting.
As shown in fig. 1 to 3, the waterproof earphone jack of the present invention includes a plastic body 10, a terminal 20, a back cover 30, and a FPCB circuit board, and is fabricated by the process of fabricating the waterproof earphone jack provided by the present invention, as shown in fig. 4, the process of fabricating the waterproof earphone jack includes
Step S10: placing the plastic body 10 and the rear cover 30 into an oven for baking;
step S20: inserting the terminal 20 into the dried plastic body 10, and covering the dried rear cover 30 on the plastic body 10 to cover the terminal 20;
step S30: dispensing glue between the plastic body 10 and the terminal and between the plastic body 10 and the rear cover 30 and solidifying the glue into a sealing glue block 40 to form a finished waterproof earphone base;
step S40: and welding the FPCB circuit board with the extending end of the terminal 20 in the finished waterproof earphone seat.
After the plastic body 10 and the rear cover 30 are injection molded and before the plastic body 10 and the rear cover 30 are assembled, the plastic body 10 and the rear cover 20 are baked to convert all water absorbed by the plastic body 10 and the rear cover 30 into gas to be released, then the plastic body 10, the terminal 20 and the rear cover 30 are assembled, glue is dispensed and sealed at the joints between the plastic body 10 and the rear cover 30, between the plastic body 10 and the extending end of the terminal 20 and between the rear cover 30 and the extending end of the terminal 20 (after glue dispensing is finished, a layer of sealing glue block 40 is formed on the rear cover 30), and then the extending end of the terminal 20 is connected with the FPCB through welding, so that the assembly of the waterproof earphone seat is finished. Because toast plastic body 10 and back lid 30 earlier before carrying out the equipment assembly work, the moisture of plastic body 10 and back lid 30 has been got rid of, therefore can not produce gas again and lead to between plastic body 10 and back lid 30 when welding the FPCB circuit board, the sealed gluey piece 40 of the junction between the end that stretches out between plastic body 10 and terminal 20 and the end that stretches out between back lid 30 and terminal 20 is broken, or plastic body 10 produces great gap owing to shrink after being heated after the welding, lead to the impaired problem of waterproof performance of waterproof earphone seat, waterproof function is qualified promptly.
In order to stabilize the sealing effect between the sealing rubber block 40 formed by the glue and the plastic body 10, a stepped structure is formed on the inner side wall of the plastic body 10, and after the glue drops on the stepped structure, the glue forms a sealing structure matched with the stepped structure so as to better seal the joint of the glue and the plastic body 10.
Preferably, the FPCB circuit board and the terminal 20 are soldered using a solder-reflow soldering method.
In the manufacturing process of the waterproof earphone jack of the present invention, in the step S10, the temperature of the baked plastic body 10 and the rear cover 30 is controlled to be 110 ℃ to 120 ℃, and preferably, the plastic body 10 and the rear cover 30 are baked at 118 ℃ to remove moisture.
After step S10 is completed and before step S20 is performed, the plastic body 10 and the rear cover 30 are cooled to the normal temperature of the predetermined indoor environment (the predetermined indoor environment is the environment of the workshop for producing the waterproof earphone seat, and the normal temperature in the workshop is generally set to be between 20 ℃ and 25 ℃). Can avoid the staff to be scalded by plastic body 10 or back lid 30 after toasting at the in-process of assembly like this, also be favorable to preventing simultaneously that plastic body 10 or back lid 30 from producing the thermal stress error and leading to waterproof function not good when the equipment.
Of course, the above manufacturing process is not limited to be applied to the production of waterproof earphone sockets, and is also applicable to waterproof connector products with other similar process structures.
As shown in fig. 1 to 4, according to another aspect of the present invention, a waterproof earphone jack is provided. In the present invention, the waterproof earphone jack includes a plastic body 10, a terminal 20, a back cover 30 and a FPCB circuit board, and the plastic body 10, the terminal 20, the back cover 30 and the FPCB circuit board are manufactured by the manufacturing process of the waterproof earphone jack. The waterproof earphone seat is manufactured by the manufacturing process, and the sealing rubber blocks 40 at the joints between the plastic body 10 and the rear cover 30, between the plastic body 10 and the extending end of the terminal 20 and between the rear cover 30 and the extending end of the terminal 20, which are broken by gas formed when the FPCB and the terminal 20 are subjected to reflow soldering by moisture, are eliminated, so that the waterproof performance of the waterproof earphone seat is more excellent.
According to another aspect of the present invention, there is provided a mobile terminal including the waterproof earphone jack described above, wherein the waterproof earphone jack is connected to an earphone, so that a waterproof function is achieved, and a user can listen to songs, receive calls, and the like even under water.
