This application claims priority to Chinese Patent Application No. 202120517862.7 filed Mar. 11, 2021 and Chinese Patent Application No. 202110265487.6 filed Mar. 11, 2021, the disclosures of which are incorporated herein by reference in their entireties.
The present disclosure relates to the technical field of data transmission and, in particular, to a method for manufacturing a data transmission apparatus and a data transmission apparatus.
A universal serial bus (USB) type-C joint is a connector that can be plugged into a docking connector and electrically connected to the main circuit board to provide an electrical connection between the two electrical devices. Specifically, one end of the joint is a USB interface while the other end of the joint is a type-C interface.
In the related art, when a USB type-C joint is manufactured, an encapsulation housing is prepared first. A conductive terminal is then inserted into the encapsulation housing. One end of the conductive terminal is embedded into the upper surface of one end of the encapsulation housing while the other end of the conductive terminal extends outward from the other end of the encapsulation housing. A printed circuit board (PCB) is subsequently secured to the other end of the encapsulation housing and electrically connected to the other end of the conductive terminal. The type-C jack is finally connected to the end of the PCB facing away from the encapsulation housing.
It can be seen that the technique for manufacturing the USB type-C joint in the related art is relatively complex, and the finished USB type-C joint is relatively large in size.
An object of the present disclosure is to provide a method for manufacturing a data transmission apparatus and a data transmission apparatus. This method enables the data transmission apparatus to be simply-manufactured and to be shorter and smaller.
As conceived above, the present disclosure provides the solutions below.
A method for manufacturing a data transmission apparatus includes the steps below.
In S1, a first connecting finger is formed at a first end of a printed circuit board.
In S2, a second connecting finger is formed at a second end of the printed circuit board.
In S3, a type-C female base is secured to the second end of the printed circuit board and electrically connected to the second connecting finger.
In S4, a conductive contact is attached to the first connecting finger.
In S5, an internal mold is encased around the printed circuit board and the type-C female base, and the conductive contact is exposed out of the internal mold.
In S6, a metal housing is sleeved on one end of the internal mold facing away from the type-C female base, a socket is formed by the metal housing and the internal mold, and the conductive contact is exposed in the socket.

The present embodiment provides a method for manufacturing a data transmission apparatus for manufacturing the data transmission apparatus. The manufacturing process is relatively simple.
As shown in
In S1, a first connecting finger 33 is formed at a first end of a printed circuit board 3.
One printed circuit board 3 is prepared first, the shape of which may be determined according to the needs of the data transmission apparatus. As shown in
In S2, a second connecting finger 32 is formed at the second end of the printed circuit board 3.
The second connecting finger 32 is formed at the second end of the printed circuit board 3. The second connecting finger 32 may be electrically connected to the first connecting finger 33 through the conductive wires inside the printed circuit board 3. The number and shape of the second connecting finger 32 are determined according to actual needs. For example, the number of the second connecting finger 32 is the same as the number of the contact terminal 52 on the type-C female base for electrical connection to the contact terminal 52. The printed circuit board 3 after the first connecting finger 33 and the second connecting finger 32 are formed is shown in
It is to be noted that the sequence of S1 and S2 may be adjusted according to actual situations. For example, the second connecting finger 32 is formed before the first connecting finger 33 is formed. Alternatively, the first connecting finger 33 and the second connecting finger 32 are formed at the same time. This is not limited in the present embodiment.
In S3, a type-C female base 5 is secured to the second end of the printed circuit board 3 and electrically connected to the second connecting finger 32.
After the second connecting finger 32 is formed, the type-C female base 5 is secured to the second end of the printed circuit board 3 such that the contact terminal 52 of the type-C female base 5 is electrically connected to the second connecting finger 32 so as to electrically connect the type-C female base 5 to the first connecting finger 33 through the second connecting finger 32 and the conductive wires inside the printed circuit board 3 for transmitting data or power.
In S4, a conductive contact 4 is attached to the first connecting finger 33.
After the first connecting finger 33 is formed, the conductive contact 4 may be attached to the first connecting finger 33 for electrical connection to other structures through the conductive contact 4. A plurality of conductive contacts 4 and a plurality of first connecting fingers 33 are provided. The plurality of conductive contacts 4 are in one-to-one correspondence with the plurality of first connecting fingers 33. Each of the plurality of conductive contact 4 of is attached to a corresponding one of the plurality of first connecting fingers 33.
It is to be noted that the conductive contact 4 may be instantly formed on the first connecting finger 33 after the first connecting finger 33 is formed to reduce the time of the first connecting finger 33 exposed outside.
In S5, an internal mold 11 is encased around the printed circuit board 3 and the type-C female base 5, and the conductive contact 4 is exposed out of the internal mold 11.
After the type-C female base 5 is secured to the printed circuit board 3, the insulating internal mold 11 is needed to encase around the printed circuit board 3 and the type-C female base 2 to improve the stability of the connection between the type-C female base 5 and the printed circuit board 3. Exemplarily, the internal mold 11 is injection molded around part of the printed circuit board 3 and part of the type-C female base 5. As shown in
In S6, a metal housing 2 is sleeved on one end of the internal mold 11 facing away from the type-C female base 5, a socket is formed by the metal housing 2 and the internal mold 11, and the conductive contact 4 is exposed in the socket.
After the internal mold 11 is formed, as shown in
Optionally, in S6, the metal housing 2 is tin soldered to the internal mold 11 so as to improve the robustness of the connection between the metal housing 2 and the internal mold 11.
In the method for manufacturing a data transmission apparatus provided by the present embodiment, with the configuration in which the first connecting finger 33 and the second connecting finger 32 are formed at both ends of the printed circuit board 3, the type-C female base 5 can be electrically connected to the printed circuit board directly through the second connecting finger 32. Compared with the manner of electrical connection by use of a conductive terminal, a smaller space is occupied so that the data transmission apparatus is shorter and smaller and so that the development of the data transmission apparatus is facilitated. Compared with the method in which a contact is disposed on an encapsulation housing in the related art, the configuration in which the conductive contact 4 is directly disposed on the first connecting finger can reduce the space occupied by the encapsulation housing, making the data transmission apparatus further smaller in size and facilitating manufacturing of the data transmission apparatus.
Further, after S6, the method for manufacturing a data transmission apparatus further includes a step below.
In S7, an external mold 12 is encased around the type-C female base 5 and the metal housing 2.
The external mold 12 may encase the rest parts except the interface of the type-C female base 5 to fully protect the type-C female base 5 so as to prevent electric leakage and other situations. As shown in
In the present embodiment, before the preceding S3, the method for manufacturing a data transmission apparatus further includes steps as follows. The second end of the printed circuit board 3 is provided with a plughole 31, and in S3, a pin 51 on the type-C female base 5 is inserted into the plughole 31 so as to connect the type-C female base 5 to the second end of the printed circuit board 3. Exemplarily, the inner wall of the plughole 31 may have a conductive structure. At the time, the type-C female base 5 may be electrically connected to the printed circuit board 3 through the pin 51 and the plughole 31, thereby improving the reliability of the connection between the type-C female base 5 and the printed circuit board 3.

The present embodiment further provides a data transmission apparatus that is manufactured by the preceding method for manufacturing a data transmission apparatus.
As shown in
The metal housing 2 is connected to one end of the internal mold 11. A socket is formed by the metal housing 2 and the internal mold 11. The printed circuit board 3 is disposed inside the internal mold 11. A conductive contact 4 is attached to a first connecting finger 33 at a first end of the printed circuit board 3, and the conductive contact 4 is exposed in the socket. The type-C female base 5 is electrically secured to a second end of the printed circuit board 3 and electrically connected to a second connecting finger 32 at the second end of the printed circuit board 3. The type-C female base 5 is electrically connected to the conductive contact 4 through the printed circuit board 3.
In the data transmission apparatus provided by the present embodiment, the socket for connection to the USB interface is formed by the insulating housing 1 and the metal housing 2, and the conductive contact 4 located in the socket is directly disposed at the first end of the printed circuit board 3. Compared with the method in which a contact is disposed on an encapsulation housing in the related art, the preceding configuration can reduce the space occupied by the insulating housing 1. Compared with the manner of electrical connection by use of a conductive terminal, the type-C female base 5 is directly secured to the second end of the printed circuit board 3. In this manner, a smaller space is occupied so that the data transmission apparatus shorter and smaller and so that the development of the data transmission apparatus is facilitated.

The pin 51 and the contact terminal 52 are disposed on the other surface of the stepped structure, and the second end of the printed circuit board 3 is lap joined on the stepped structure.
In the present embodiment, as shown in
Further, one side surface of the stepped surface is flush with one side of the female base body 53, and one side of the printed circuit board 3 not in contact with the stepped structure can be flush with the other side of the female base body 52 or located under the other side of the female base body 52, so that the direct connection between the printed circuit board 4 and the type-C female base 5 does not increase the thickness of the data transmission apparatus, making the data transmission apparatus smaller.
The second length of the data transmission apparatus provided by the present embodiment is about 20.2 mm, about 10 mm smaller than the second length of the data transmission apparatus in the related art, which is conducive for making the data transmission apparatus smaller.
