Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the connection/connection relations referred to in the patent do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection auxiliary components according to specific implementation conditions. The utility model discloses each technical feature in the creation can the interactive combination under the prerequisite that does not contradict conflict each other.

Referring to fig. 1, a Type-C changes waterproof Type adapter of power source, includes plastic casing 1, the female seat of Type-C, PCB board 4 and round needle 5, the female seat of Type-C, PCB board 4 and contact pin all set up in plastic casing 1, still be provided with the waterproof construction who carries out the protection to the female seat of Type-C and PCB board 4 on the plastic casing 1. Waterproof construction sets up on tip that the plastic can and plastic casing 1, carries out waterproof sealing to the exposed part in 1 parcel spaces of plastic casing, makes power adapter use under the environment of humidity, increases power adapter's security.

Referring to fig. 2 and 3, the Type-c female socket comprises a metal shell 2, a Type-c female socket terminal 3 and a resistance component 6, wherein the Type-c female socket terminal 3 and the resistance component 6 are located in the metal shell 2. Female seat terminal 3 of Type-c is including arranging needle, terminal pad and 5 pads of round pin, the row's of female seat terminal 3 of Type-c pin leg is concentrated to the inboard and is arranged, concentrates the terminal leg of arranging to the inboard and can save the welding space in the metal-back, reduces power adapter's whole size, makes power adapter carry more convenient. The terminal pads are arranged in the center, and the round pin 5 pads are arranged on two sides, so that the size of the adapter can be reduced.

The adapter welded by the metal shell 2 can keep the communication of the internal circuit, and the metal shell 2 is arranged in the plastic shell 1 to block the circuit, so that people can be prevented from contacting with the current in the use process. When the metal shell 2 is installed in the plastic housing 1, it is difficult to maintain the stability of the connection by the friction connection between the two. Therefore, the metal shell 2 is further provided with an inverted structure 21, the plastic shell 1 is provided with a slot 11 matched with the inverted structure 21, and the inverted structure 21 is arranged at one end of the metal shell 2 close to the soldering leg of the female terminal. The reversing structure 21 is a bending block arranged at the end part of the metal shell 2, the bending block is arranged at the end part of the metal shell 2 in a reverse inclined mode, and the bending block is reversely inserted into the slotted hole 11. When the number of pieces of outer shells is inserted from the tail part of the plastic shell 1, the obliquely arranged bending block is pressed by the inner wall of the plastic shell 1 to generate slight elastic deformation. When the metal shell 2 is pushed into the slot hole 11 of the plastic shell 1, the end of the bending block extends into the slot hole 11, the elastic deformation returns, the end of the bending block is not clamped in the slot hole 11, and the back-off locking of the metal shell 2 and the plastic shell 1 is completed. The stability of being connected between metal casing 2 and the plastic casing 1 has been increased in the setting of back-off structure 21, has increased the quality of connecting the dress.

The slotted holes 11 are arranged on two long sides of the plastic shell 1, and the bending blocks are arranged on two sides of the end part of the metal shell 2. The slotted hole 11 arranged on the long side of the plastic shell 1 is a through groove, therefore, the waterproof rubber ring 8 is arranged outside the plastic shell 1, and the waterproof rubber ring 8 is positioned outside the slotted hole 11 on the plastic shell 1. The setting of waterproof rubber ring 8 can seal slotted hole 11, prevents that the human body from contacting the metal back-off in the slotted hole 11, can also prevent that water smoke etc. from entering into plastic casing 1 when using under the special circumstances in, avoids the damage of the connector internal circuit because of intaking and causing. Waterproof construction is still including setting up epoxy glue 7 at 1 afterbody of plastic casing, epoxy glue 7 sets up in plastic casing 1 after inserting the female seat of Type-c. After the welding of the relevant part of the female seat of Type-c was accomplished, longer round needle 5 can stretch out the scope of plastic casing 1, consequently adopts the mode that glue was filled when sealing up plastic casing 1, directly pours epoxy glue 7 into at the installation and 1 afterbody of plastic casing after the welding was accomplished, treats that glue solidifies, has just accomplished the waterproof sealing to the connector.

While the preferred embodiments of the present invention have been described, the present invention is not limited to the above embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
