Description

Technical Field

[0001] This application relates to the technical field of electronic device connector devices, and specifically to a Type-C interface. Background Art

[0002] Because the Type-C connection interface has the advantages of being convenient without the need to distinguish between the front and back, and more functions, the Thunderbolt protocol and USB4 with higher transmission bandwidths also adopt the Type-C connection interface. As an interface for transmitting data and daily charging, the Type-C connection interface is becoming more and more popularly applied to various electronic products.

[0003] In addition to the terminal pins with basic charging functions, the Type-C connection interface also has more than a dozen other terminal pins with other functions for connecting and transmitting signals. The Type-C interface, like the power-on / off and lock screen buttons on electronic products, is frequently used by users daily and is prone to wear and failure. Especially when users connect the Type-C male head and the Type-C female socket at random angles, it is also easy to cause deformation of the Type-C interface and short circuit due to the overlapping of terminal pins. Therefore, the structural strength inside the Type-C interface is particularly important. Especially because of the development and strength of the electronic device CUP chip, for example, many users have changed from the frequency of replacing mobile phones every 2 or 3 years to about 5 years, and it is even more necessary for the Type-C interface to have a long service life to avoid the burden on users to repair and replace the Type-C interface.

[0004] In the prior art, as disclosed in a patent document with the patent application number CN202123368937.9, an improved high-speed electrical connector is designed such that the connector housing 1 is integrated with the grounding ends of the upper row of terminals 2, the lower row of terminals 4, and the middle clip 3. In fact, due to the difficulty in constantly ensuring that the manufacturing tolerances of micro-components reach the standard values, please refer to the accompanying drawings of the specification Figure 1 ., the terminal pins on the upper row of terminals 2 and the lower row of terminals 4 will make electrical connections with the middle clip 3 through a plurality of continuously spaced holes A, resulting in a short circuit.

[0007] Wherein, the rubber-coated housing is connected by rubber-coated injection molding to cover and enclose the first terminal connection plate, the second terminal connection plate, the first clamping connection piece, and the second clamping connection piece, and both ends of the clamping hook portion and the plurality of terminal pins extend out of the rubber-coated housing, and the plastic flow of the rubber-coated housing fills the long-strip connection holes and the fixing holes.

[0008] Further, both the first clamping connection piece and the second clamping connection piece are made of metal and are electrically connected to the ground terminal pins among the plurality of terminal pins.

[0029] Please refer to Figure 2 - Figure 8, this embodiment provides a Type-C interface, including a first terminal connection plate 1, a second terminal connection plate 2, a first clamping connection piece 3, a second clamping connection piece 4, and a rubber-coated housing 5; both the first terminal connection plate 1 and the second terminal connection plate 2 are provided with a plurality of terminal pins 6 connected by clamping; both the first clamping connection piece 3 and the second clamping connection piece 4 are arranged between the first terminal connection plate 1 and the second terminal connection plate 2, fixedly connected to the first terminal connection plate 1 and the second terminal connection plate 2, and distributed at the left and right sides; the first clamping connection piece 3 and the second clamping connection piece 4 have the same structure and are symmetrically arranged, and there is no contact between them; both the first terminal connection plate 1 and the second terminal connection plate 2 are provided with through long-strip connection holes 150; the contour area of the long-strip connection hole avoids the contour area where the first clamping connection piece and the second clamping connection piece are located; one end of both the first clamping connection piece 3 and the second clamping connection piece 4 is provided with a clamping hook portion 350 extending out of the outer contour of the first terminal connection plate 1 and the second terminal connection plate 2; and both the first clamping connection piece 3 and the second clamping connection piece 4 are provided with through fixing holes 360 adjacent to the clamping hook portion 350.

[0030] Among them, the rubber-coated housing 5 is connected by rubber-coated injection molding to wrap and enclose the first terminal connection plate 1, the second terminal connection plate 2, the first clamping connection piece 3, and the second clamping connection piece 4, and both ends of the clamping hook portion 350 and the plurality of terminal pins 6 extend out of the rubber-coated housing 5. The plastic flow of the rubber-coated housing 5 fills the long-strip connection hole 150 and the fixing hole 360, firmly fixing the first terminal connection plate 1, the second terminal connection plate 2, the first clamping connection piece 3, and the second clamping connection piece 4 as a whole.

[0031] The Type-C interface can also be called a Type-C female socket. The clamping hook portion 350 is used to cooperate with the clamping structure in the Type-C plug, which can also be called a Type-C male head, to stably connect the Type-C interface and the Type-C plug.

[0032] By designing the long-strip connection holes 150 of the first terminal connection plate 1 and the second terminal connection plate 2 as long-strip connection holes, compared with the prior art where they are designed as several consecutive spaced holes A, it is easier to process in both machining and injection molding, easier to control tolerances, the dimensions are more accurate, and the plastic flow of the rubber-coated housing 5 fills the long-strip connection hole 150 more fully, making the connection with the first terminal connection plate 1 and the second terminal connection plate 2 more stable.

[0033] By avoiding the contour area of the long strip-shaped connection hole 150 from the contour areas where the first clamping connection piece 3 and the second clamping connection piece 4 are located, it is possible to prevent short circuits caused by the connection of the terminal pins 6 located in the long strip-shaped connection hole 150 to the first clamping connection piece 3, the second clamping connection piece 4, and the battery cells.

[0034] Preferably, both the first clamping connection piece 3 and the second clamping connection piece 4 are made of metal and are electrically connected to the ground terminal pins among the plurality of terminal pins 6.

[0035] Please refer to Figure 6 and Figure 8 , both the first terminal connection plate 1 and the second terminal connection plate 2 are provided with clamping grooves 160, and the clamping grooves 160 clamp and accommodate a plurality of the terminal pins 6; the clamping grooves 160 are provided on the end face sides of the first terminal connection plate 1 and the second terminal connection plate 2 away from the first clamping connection piece 3 and the second clamping connection piece 4.

[0036] This structure can effectively separate each terminal pin 6, prevent electrical connection caused by short circuits, and fully fix the terminal pins 6.

[0037] At the same time, the risk of short circuits of the terminal pins 6 in the first terminal connection plate 1 and the second terminal connection plate 2 is avoided.

[0038] Please refer to Figure 8 , the long strip-shaped connection hole 150 is provided in the middle of the first terminal connection plate 1 and the second terminal connection plate 2.

[0039] This structural position is reasonably designed, so that the middle parts of the first terminal connection plate 1 and the second terminal connection plate 2 are filled with the plastic flow of the encapsulation housing 5, forming a connection with high structural strength and stability. In addition, the first terminal connection plate 1 and the second terminal connection plate 2 are also provided with additional through holes for the plastic flow of the encapsulation housing 5 to fill.

[0040] In addition, this setting can greatly increase the distance between the terminal pins 6 in the long strip-shaped connection hole 150 and the first clamping connection piece 3 and the second clamping connection piece 4, avoiding short circuits and improving insulation and withstand voltage problems caused by the relatively short distance.

[0041] Please refer to Figure 6 and Figure 7 , the opposite end faces of the first terminal connection plate 1 and the second terminal connection plate 2 are provided with a plugging convex column 170 and a plugging concave hole 180 for matching plugging connection.

[0042] This structure is easy to process and manufacture, and is convenient for assembly.

[0043] Please refer to Figure 5Both the first clamping connection piece 3 and the second clamping connection piece 4 are provided with positioning holes 370 through which the plug-in convex posts 170 pass.

[0044] Preferably, at least two positioning holes 370 are provided on each of the first clamping connection piece 3 and the second clamping connection piece 4.

[0045] With this structure, the first clamping connection piece 3 and the second clamping connection piece 4 can be fully fixed, preventing loosening and displacement when they are connected to the plug.

[0046] Please refer to Figure 5 and Figure 6 , the plug-in convex posts 170 and the plug-in concave holes 180 corresponding to the positioning holes 370 are arranged alternately.

[0047] This structure means that instead of all the plug-in convex posts 170 being provided on the first terminal connection plate 1 and all the plug-in concave holes 180 being provided on the second terminal connection plate 2, both the first terminal connection plate 1 and the second terminal connection plate 2 are provided with plug-in convex posts 170 and plug-in concave holes 180.

[0048] Please refer to Figure 1 and Figure 2 , including a stamped metal shell 7, the stamped metal shell 7 covering the rubber-coated housing 5.

[0049] By means of the stamped metal shell 7, the structural strength of the Type-C interface can be enhanced.
