[0039] In some embodiments, as Figures 1 to 3 The utility model provides a kind of Type-C connector of short-circuit or high-voltage bad prevention, it includes: shell 100, inner shell 200, plastic main body 300, upper terminal row 400, lower terminal row 500, first middle clamping piece 600 and second middle clamping piece 700. Wherein, the upper terminal row 400 and the lower terminal row 500 are respectively arranged on the end face and bottom surface of the plastic main body 300;The inner shell 200 is sleeved on the plastic main body 300;The shell 100 is sleeved on the inner shell 200;The first middle clamping piece 600 is located between the negative pole terminal of the upper terminal row 400 and the lower terminal row 500 and is exposed to one side of the plastic main body 300;The second middle clamping piece 700 is located between the negative pole terminal of the upper terminal row 400 and the lower terminal row 500 and is exposed to the other side of the plastic main body 300.

[0040] Specifically, the waterproof Type-C connector is female seat, and in some embodiments, the Type-C connector is horizontal Type-C connector. The inner shell 200 has a cavity with two ends communicating, and the plastic main body 300 is accommodated in the cavity of the inner shell 200. The upper terminal row 400 and the lower terminal row 500 are respectively distributed on the upper end face and the lower end face of the plastic main body 300, and the upper terminal row 400 and the lower terminal row 500 realize the same function, so that the Type-C connector can realize positive and negative insertion.

[0041] The first middle clamping piece 600 and the second middle clamping piece 700 are located between the upper terminal row 400 and the lower terminal row 500 and are located at two sides of the plastic main body 300 respectively, and the first middle clamping piece 600 and the second middle clamping piece 700 are provided with a hook structure. One end of the inner shell 200 forms an interface part of a Type-C connector, and when a female seat of the Type-C connector is connected with a male head of the Type-C connector, the hook structure on the first middle clamping piece 600 and the second middle clamping piece 700 can be connected with a hook of the male head of the Type-C connector, so as to enhance the connection stability, and the terminal row of the female seat of the Type-C connector can be connected with the terminal row of the male head of the Type-C connector, so as to realize data transmission or charging.

[0042] It needs to be understood that according to the definition of the Type-C connector interface, the outermost terminal row is a negative terminal, the shell 100 is usually connected with the negative terminal, and the middle clamping piece is in contact with the shell 100, so the middle clamping piece is indirectly connected with the negative terminal of the terminal row. In order to prevent the middle clamping piece from causing the positive terminal of the upper terminal row 400 and the lower terminal row 500 to be in contact with the middle clamping piece and cause short circuit, the utility model divides the traditional middle clamping piece into two parts, that is, the first middle clamping piece 600 and the second middle clamping piece 700, and the two parts are distributed at two sides of the plastic main body 300. In this way, not only the function of the middle clamping piece itself can be realized, but also the positive terminal of the upper terminal row 400 and the lower terminal row 500 is avoided, that is, even if the upper terminal row 400 and the lower terminal row 500 are in contact with the first middle clamping piece 600 or the second middle clamping piece 700 due to process problems, only the negative terminal of the upper terminal row 400 and the lower terminal row 500 is in contact with the first middle clamping piece 600 or the second middle clamping piece 700, and the short circuit of the positive terminal and the negative terminal of the upper terminal row 400 and the lower terminal row 500 can be avoided, so that the product can be protected from damage. In addition, by avoiding the positive terminal of the upper terminal row 400 and the lower terminal row 500 from the middle clamping piece, the problem of high-voltage failure (the positive terminal of the upper terminal row 400 and the lower terminal row 500 is very close to the middle clamping piece, which may cause an electric spark problem) causing the plastic main body of the Type-C connector to be burned out is also avoided.

[0043] In some embodiments, referring to Figure 1 , one end of the inner shell 200 protrudes from the shell 100; the Type-C connector for preventing short circuit or high-voltage failure further comprises a waterproof rubber ring 800; the waterproof rubber ring 800 is arranged on the one end of the inner shell 200 protruding from the shell 100.
