Background technique

The most popular signal transmission specification for computer equipment today is Universal Serial Bus (USB for short). and so on, it is immediately measured by the computer and used immediately.

At present, both the USB socket and the USB connector are one-way electrical connection. In order to ensure that the USB socket can be electrically connected when inserted into the USB socket, the two have a fool-proof design on the docking, that is, when the USB socket is inserted backwards, it cannot be inserted. It will be inserted in another direction, and the direction will be correct to insert, so as to ensure that there is an electrical connection after insertion.

At present, there are two specifications of USB 2.0 and 3.0. Please refer to FIG. 1 and FIG. 2. It is the existing USB 2.0 specification and has a plate type connector. The disk 1 is provided with a plastic base 10 and a circuit board. 15. The rear section of the circuit board 15 is covered by the plastic base body 10 , and only one surface of the front section of the circuit board 15 is exposed outside the plastic base body 10 , and the board surface is provided with a row of four contacts 16 .

Please refer to FIG. 3 , which is an electrical connection socket 20 of the existing USB2.0 specification, which is provided with a metal shell 25 and a tongue piece 22 . A connection groove 21 is formed in the metal shell 25 , and the tongue piece 22 is located in the The groove is on the upper side, and only the lower part of the tongue is provided with a row of four contacts 23 .

Please refer to FIG. 4 , in use, the USB flash drive 1 must be inserted into the connecting slot 21 with the contacts 16 facing upwards to be electrically connected to a row of contacts 23 located under the tongue 22 , and the four elastic pieces 24 are pressed against the disc body Disc 1: If the disc body disc 1 is inserted into the connection slot 21 on the reverse side, it cannot be electrically connected. The user usually inserts it randomly, so the probability of not inserting it is 1/2, so it is often inserted twice, which causes inconvenience in use.

For the convenience of use, it is still necessary to use both positive and negative electrical connections to better meet the requirements. Therefore, the applicant has developed an electronic device with double-sided electrical connection function. To function, the connector must be designed with two rows of contacts. However, in use, the spring piece 24 of the electrical connection female base may contact the contacts of the other board surface and cause a short circuit, so this problem must be overcome.

The applicant of the present invention has devoted himself to researching the double-sided plug-in design of the above-mentioned products, and finally proposes an improved product structure to overcome the above-mentioned potential problems.

In order to make the examination smooth, the description of the embodiments of independent claims 1-12 is mainly implemented in the embodiments of Fig. 14-15, Fig. 22-24, and Fig. 25-32, etc.; -18, claim 3 combined application Figures 111-116, claim 4 combined application Figure 75-77, 96, 97, claim 5 combined application Figure 17-18, claim 6 combined application Figure 58-59, claim 7 Combined application Figures 49-51, 56-58, claim 8 combined application Figure 49-51, 56-59 implemented, claim 9 combined application Figure 61-63, 69-71, 111-116, claim 10 combined application Figures 75-77, claim 11 is applied in combination with Figures 111-116, and claim 12 is applied in combination in Figures 9, 47-48.
