Description

Technical Field

[0001] The utility model relates to a connector, in particular to an electric connector with a structure for reducing the generation of corrosive substances when sweat invades. Background Art

[0002] See also Figures 10 to 12 , Figure 10 ' is a stereoscopic view of the tongue 10' in a USB TYPE-C female connector, wherein the tongue 10' includes an insulating terminal seat 70' and a terminal group 20' fixedly disposed inside the insulating terminal seat 70', wherein the terminal group 20' is provided with a plurality of terminals 21', wherein the terminals 21' are fixedly disposed in the insulating terminal seat 70', wherein the terminal group 20' does not include all pins, and the insulating terminal seat 70' forms a larger space s21' between the terminals 21' closest to the left and right sides and the terminals 21' next closest to the left and right sides, and the insulating terminal seat 70' extends to cover the space s21'. After sweat penetrates the electrical connector, the range of sweat flow is roughly within the front end of the tongue 10', that is, the area where the terminal 21' is exposed on the insulating terminal seat 70', and the surface of the space s21' is too flat, so that the path cr1' along the insulating surface between the terminal 21' closest to the left and right sides and the terminal 21' next closest to the left and right sides is short (that is, the creepage distance is small). As a result, when power is turned on, the electric field formed between the above two terminals 21' is strong, providing a strong driving force for the electrochemical reaction, which promotes the occurrence of corrosion and produces more corrosive products accumulated on the front end surface of the tongue 10', causing the electrical connector to be corroded and damaged.

[0003] Therefore, it is necessary to provide an electrical connector having a structure that reduces the generation of corrosion products when sweat invades. Summary of the Invention

[0004] The purpose of the present invention is to provide an electrical connector, comprising: an insulating terminal seat; a terminal group, wherein the terminal group is arranged in the insulating terminal seat and comprises a plurality of terminals, the plurality of terminals are fixed in the insulating terminal seat, and there is a first spacing space and a second spacing space between the plurality of terminals, the width of the first spacing space is greater than the width of the second spacing space; a plurality of insulating dummy terminals, wherein the insulating dummy terminals are spaced from each other and arranged in the first spacing space, and the rear ends of two adjacent insulating dummy terminals are merged to form a collecting portion, and the collecting portion extends backward to make the insulating dummy terminals present an inverted Y shape; the plug-in surface of the insulating dummy terminal and the plug-in surface of the terminal are coplanar.

[0005] In some embodiments, the insulating dummy terminal extends from the surface of the insulating terminal seat.

[0006] In some embodiments, the terminal closest to the left and right sides is separated from the terminal second closest to the left and right sides by the first spacing space, the terminal third closest to the left and right sides is separated from the adjacent terminal by the second spacing space, and a third spacing space is provided between the insulating dummy terminal and the adjacent terminal, and the width of the third spacing space is equal to that of the second spacing space.

[0007] In some embodiments, a fourth spacing space is provided between the insulating dummy terminals connected to the same collecting portion, and the fourth spacing space has the same width as the second spacing space.

[0008] As described above, the structure of the electrical connector of the present invention can lengthen the path along the insulating surface between the terminals located on the left and right sides of the missing pin position, thereby weakening the electric field formed between the two terminals when power is applied, thereby inhibiting corrosion caused by electrochemical reactions when sweat invades the electrical connector of the present invention, thereby reducing the generation of corrosive products and improving the corrosion resistance of the electrical connector of the present invention.

[0022] To explain in detail the technical content, structural features, objectives and effects of the electrical connector of the present invention, embodiments are given below with reference to the accompanying drawings.

[0023] See also Figures 1 to 4 The electrical connector 100 of the present invention is a USB TYPE-C receptacle connector and includes: a shield shell 60, a receiving space formed in the shield shell 60, a tongue 10 received in the receiving space, and a colloid 50 applied to the rear end of the tongue 10 to seal the gap between the tongue 10 and the shield shell 60. The tongue 10 includes: an insulated terminal block 70 manufactured by in-mold molding, a terminal block 20 in-mold bonded to the insulated terminal block 70, a center piece 30 disposed in the center of the terminal block 20, and two shielding pieces 40 disposed at the upper and lower ends of the rear edge of the tongue 10, respectively.

[0024] See also Figures 5 to 7 In this embodiment, the terminal assembly 20 includes a plurality of terminals 21 fixed in the insulating terminal block 70. The terminals 21 are spaced apart from each other and are only provided at pins A1, A4, A5, A6, A7, A8, A9, A12 and pins B1, B4, B5, B6, B7, B8, B9, B12, and lack terminal pins A2, A3, A10, A11, B2, B3, B10, B11, etc., which are used for high-speed signal transmission.

[0025] The insulating terminal block 70 is further provided with an insulating dummy terminal 11 at the aforementioned pins A2, A3, A10, A11, B2, B3, B10, and B11, which are missing terminals. The insulating dummy terminal 11 is raised from the surface of the insulating terminal block 70, and the rear ends of the insulating dummy terminals 11 adjacent to each other, such as the A2 and A3 pins, the A10 and A11 pins, the B2 and B3 pins, and the B10 and B11 pins, extend backward and merge into a collection portion 12, and the collection portion 12 extends backward. The external dimensions of the insulating dummy terminal 11 itself are roughly the same as those of the terminal 21, and the mating surface of the insulating dummy terminal 11 is located in the same plane as the mating surface of the terminal 21, thereby avoiding problems when the insulating dummy terminal 11 and the terminal 21 are plugged into the mating connector. Furthermore, the insulating dummy terminal 11 and the collecting portion 12 connected to the rear end of the insulating dummy terminal 11 protrude from the surface of the insulating terminal seat 70 to form an inverted Y shape.

[0026] See also Figures 6 and 7 A first spacing space s1 is defined between the terminals (A1, A12, B1, B12) located on the leftmost and rightmost sides of the terminal group 20 and the terminals (A4, A9, B4, B9) located next closest to the left and right sides, and a second spacing space s2 is defined between the terminals (A5, A10, B5, B10) located third closest to the left and right sides and the adjacent terminals (A4, A9, B4, B9). The width of the first spacing space s1 is greater than the width of the second spacing space s2. The insulating dummy terminal 11 is located within the first spacing space s1, and a third spacing space s3 is defined between the insulating dummy terminal 11 and the adjacent terminal 21. A fourth spacing space s4 is defined between the insulating dummy terminals 11 connected to the same converging portion 12. The widths of the second spacing space s2, the third spacing space s3, and the fourth spacing space s4 are equal.

[0027] See also Figures 7 to 9 When sweat penetrates the electrical connector 100 of the present invention, the insulating dummy terminals 11 disposed between the leftmost and rightmost terminals (A1, A12, B1, B12) and the next closest left and right terminals (A4, A9, B4, B9) lengthen the path cr1 along the insulating surface (i.e., extend the creepage distance), thereby weakening the electric field between the two terminals. This prevents the tongue 10 from being polarized when the two terminals are energized, thereby suppressing the electrochemical reaction and reducing the occurrence of corrosion, resulting in less corrosion products being deposited on the front surface of the tongue 10.

[0028] In summary, the electrical connector 100 of the present invention mitigates corrosion caused by electrochemical reactions when sweat intrudes into the electrical connector 100 by disposing the insulating dummy terminal 11 at the missing pin position of the tongue 10. The insulating dummy terminal 11 is raised from the surface of the insulating terminal block 70, and its dimensions are the same as those of the terminal 21. Furthermore, the spacing between the insulating dummy terminal 11 and the adjacent terminal 21 is the same as the spacing between the adjacent terminals 21 located near the inner side. Therefore, the insulating dummy terminal 11 can extend the path cr1 along the insulating surface between the terminals 21, reducing the electric field strength of the terminals 21 when power is applied, and reducing corrosion caused by electrochemical reactions when sweat intrudes into the electrical connector 100 of the present invention, ultimately improving the corrosion resistance of the electrical connector 100 of the present invention.

[0029] Although the present invention has been disclosed above with reference to the embodiments, they are not intended to limit the present invention. Anyone with ordinary skill in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
