The interface 100 may be a USB interface.
A method of assembling the interface 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 10.
As shown in fig. 1 to 10, the interface 100 includes a metal base 1 and a connection terminal 2, the metal base 1 defines a plugging cavity 11 therein, the connection terminal 2 is disposed in the plugging cavity 11, the connection terminal 2 includes a plurality of metal terminals 21 and a rubber base 22, and the rubber base 22 is disposed around the plurality of metal terminals 21 to divide each metal terminal 21 into a plugging portion 211 and a pin portion 212. The rubber base 22 can fix the metal terminal 21, the plug portion 211 can be plugged with an external plug, and the pin portion 212 can be connected with an electronic device inside a mobile terminal such as a mobile phone.
As shown in fig. 1 to 10, the method for assembling the interface 100 according to the embodiment of the present invention includes the following steps:
firstly, inserting the connection terminal 2 into the plugging cavity 11 from the front end (the front end shown in fig. 2) of the plugging cavity 11 and making the pin parts 212 of the plurality of metal terminals 21 extend out of the plugging cavity 11 so as to facilitate the connection of the pin parts 212 with electronic devices inside the mobile terminal such as a mobile phone;
then, the waterproof glue 3 is injected between the outer peripheral wall of the glue seat 22 and the inner peripheral wall of the plugging cavity 11, and the waterproof glue 3 can effectively improve the waterproofness and the insulativity of the interface 100, so that the reliability of the interface 100 is effectively improved, the service life of the interface 100 is prolonged, and the use cost is reduced;
finally, a part of the rear end of the metal base 1 is bent to abut against the rear end face of the rubber base 22, whereby the connection terminal 2 can be prevented from moving backward (backward as shown in fig. 2) in the plug cavity 11. When the plug is inserted into the plugging cavity 11 and connected with the metal terminal 21, the plug can apply a backward force to the metal base 1, and at this time, the bent part at the rear end of the metal base 1 abuts against the rear end face of the rubber base 22, so that the rubber base 22 can be prevented from moving backward in the plugging cavity 11, and the reliability of connection between the plug and the metal terminal 21 is ensured.
According to the assembling method of the interface 100 of the embodiment of the invention, not only the connection between the connection terminal 2 and the external plug and the electronic device inside the mobile terminal are facilitated, but also the reliability of the connection between the connection terminal 2 and the external plug and between the connection terminal 2 and the electronic device inside the mobile terminal can be improved. And simultaneously, the waterproof performance of the interface 100 can be improved, so that the working reliability of the interface 100 is improved.
In some embodiments of the present invention, as shown in fig. 2 and 5, a portion of each of the left and right sides of the metal base 1 is bent to define a side abutting member abutting on the rear end surface of the rubber base 22. For example, in the example shown in fig. 2 and 5, the side abutment may be defined by a portion of the metal holder 1 being cut apart from the remaining portion and then bent toward the center of the rubber holder 22. Therefore, the situation that the abutting piece is arranged independently can be avoided, and the abutting piece is connected to the metal base 1 through welding or threaded fasteners, so that the machining procedure of the metal base 1 can be simplified, the assembly time is saved, and the production efficiency is improved. Meanwhile, the side stopper may block the rubber seat 22 from moving backward, so that when the plug is connected to the connection terminal 2 by plugging, the reliability of connection between the metal terminal 21 and the plug may be improved.
As shown in fig. 2 and 5, the side stopping member includes four sub stopping members 12, and two sub stopping members 12 are disposed at the rear end of the left side wall and the rear end of the right side wall of the metal base 1. Therefore, the limiting effect of the stop member on the rubber seat 22 can be further enhanced, the rubber seat 222 is effectively prevented from moving backwards in the plugging cavity 11, and the reliability of connection between the metal terminal 21 and the plug can be improved when the plug is plugged and connected with the connecting terminal 2.
Further, as shown in fig. 2 and 5, the free ends of the two sub abutments 12 located on the same side extend obliquely toward each other. Therefore, in the direction from the end of the sub abutting part 12 connected with the metal base 1 to the free end of the sub abutting part 12, the distance between the two sub abutting parts 12 is gradually reduced, so that on one hand, the structural strength of the sub abutting part 12 can be improved, on the other hand, the contact area between the sub abutting part 12 and the rear end face of the rubber base 22 can be increased, and the limiting effect of the abutting part 12 on the rubber base 22 is enhanced.
In some embodiments of the present invention, as shown in fig. 2 and 5, a part of the top of the metal base 1 is bent downward to stop against the rear end face of the rubber base 22. Therefore, the part can play a certain limiting role on the rubber base 22 on the rear end face of the rubber base 22, and the rubber base 22 is prevented from moving backwards in the plugging cavity 11, so that when the plug is plugged and connected with the connecting terminal 2, the reliability of connection between the metal terminal 21 and the plug can be improved.
For example, in the example shown in fig. 2 and 5, the rear end surface of the top wall of the metal base 1 is provided with the top abutting piece 13, the top abutting piece 13 extends on the top wall of the metal base 1 in the left-right direction, at this time, the top abutting piece 13 extends backwards from the rear end surface of the top wall of the metal base 1, and when the connection terminal 2 is installed in the plugging cavity 11, the top abutting piece 13 can be pulled to extend downwards, so that the top abutting piece 13 abuts on the rear end surface of the rubber base 22 to limit the rubber base 22.
Of course, the present invention is not limited to this, and a part of the bottom of the metal base 1 may be bent upward to stop against the rear end face of the rubber base 22.
In some embodiments of the present invention, as shown in fig. 2 and 5, the rear end surface of the glue holder 22 is provided with a glue injection boss 221 protruding rearward. Specifically, the glue injection boss 221 may be formed in a ring shape. In the assembling process, the waterproof glue 3 may be filled between the glue injection boss 221 and the glue holder 22.

After being equipped with waterproof step 23, can block that the water on the terminal surface of gluing seat 22 towards grafting portion 211 flows to grafting surface 2111, from this, can prevent that grafting surface 2111 from meeting the rusty condition of water appearance, can also avoid metal terminal 21 to take place the short circuit simultaneously to improve the reliability of metal terminal 21 work, and then improve the reliability of the work of connecting terminal 2 of interface 100.
Note that, the height of the waterproof step 23 in the front-rear direction (the front-rear direction shown in fig. 6) is not limited as long as the waterproof step blocks water on the front end surface of the rubber seat 22 from flowing to the insertion surface 2111 of each metal terminal 21.
In some embodiments of the present invention, as shown in fig. 6-8, the plurality of pins 212 includes two ground pins 2121, with the two ground pins 2121 being defined by the same metal plate. For example, in the example shown in fig. 6 and 7, the rear end (rear end shown in fig. 7) of the metal terminal 21 located on the left side (left side shown in fig. 7) is provided with a partition hole 2122, the partition hole 2122 penetrates the metal terminal 21 in the thickness direction and the partition hole 2122 extends to the rear end face (rear end face shown in fig. 7) of the metal terminal 21 to define two ground pins 2121. Therefore, the two grounding pins 2121 are connected to the ground line to form a large-current charging loop, which effectively increases the load current of the metal terminal 21, reduces heat generation, avoids burning the charging circuit, and improves the reliability of the connection terminal 2 of the interface 100. In addition, the two grounding pins 2121 are defined by the same metal plate, so that the space of the interface 100 is fully utilized, the width of the metal terminal 21 is effectively increased, the cross-sectional area of the metal terminal 21 can be effectively increased, the charging resistance is reduced, the charging current is increased, the charging efficiency is improved, and the charging time is saved.
In some embodiments of the present invention, as shown in fig. 6-8, the plurality of pin portions 212 includes two power pins 2123, the two power pins 2123 being defined by the same metal plate. For example, in the example shown in fig. 6 and 7, the rear end (rear end shown in fig. 7) of the metal terminal 21 located on the right side (right side shown in fig. 7) is provided with a through hole 2124, the through hole 2124 penetrates the metal terminal 21 in the thickness direction and the through hole 2124 extends to the rear end surface (rear end surface shown in fig. 7) of the metal terminal 21 to define two power supply pins 2123. Therefore, the interface 100 can divide the power signal received from the power line into multiple paths through the two power pins 2123 to form a large-current charging loop, so that the load current of the metal terminal 21 is effectively increased, heat generation is reduced, the charging circuit is prevented from being burnt, and the reliability of the interface 100 is improved. In addition, the two power pins 2123 are defined by the same metal plate, so that the space of the interface 100 is fully utilized, the width of the metal terminal 21 is effectively increased, the cross-sectional area of the metal terminal 21 can be effectively increased, the charging resistance is reduced, the charging current is increased, the charging efficiency is improved, and the charging time is saved.
