[0056] In order to facilitate the understanding of the present application, the present application will be described in more detail below in combination with the drawings and specific embodiments.

[0057] The embodiment of the present application provides a Type-C female connector. Please refer to Figures 1 to 9 , the Type-C female connector 10 includes upper terminals 110 and lower terminals 120. Define the height direction and the width direction, the height direction and the width direction are perpendicular to the plugging direction of the Type-C female connector 10, in an embodiment, as shown in Figure 3 , the height direction, the width direction and the plugging direction correspond to the Y direction, the X direction and the Z direction of the space coordinate system respectively. Referring to Figure 3 , the upper terminals 110 and the lower terminals 120 are arranged at intervals along the height direction (Y direction). Referring to Figure 5 , the upper terminals 110 and the lower terminals 120 each include a plurality of terminals arranged at intervals along the width direction. Since the upper terminals 110 and the lower terminals 120 are similar in structure, the structure of the terminal in the embodiment of the present application will be described by taking the upper terminal 110 as an example. As shown in Figure 7 , the terminal has double contacts, Figure 7 a1, a2 in the terminal. The structure of forming double contacts on the terminal in the embodiment of the present application is not limited to Figure 7The structure shown only needs to form two contacts sequentially arranged along the height direction on the terminal. Figure 7 As shown, the double contacts are formed by bending the terminals. In other embodiments, the double contacts can also be formed by other forms, such as Figure 8 As shown, the double contacts are formed by designing the terminal to be forked at the front end. Any Type-C connector structure in which the terminal is designed to have a double-layer structure and each layer of terminals (110, 120) is designed to have two contacts arranged sequentially along the height direction is within the scope of protection of this application.

[0058] As described in the background technology, traditional Type-C female connectors are all single-layer structures. When the connector is loose, the male connector 20 may only contact one row of terminals of the female connector 10 and be separated from the other row of terminals, resulting in a momentary disconnection. In this application, the traditional single-layer terminal structure of the Type-C female connector 10 is innovatively changed to a double-layer terminal structure, and the upper row of terminals and the lower row of terminals traditionally integrated on a layer of tongue plate are separated into two independent terminal structures, and each layer of terminals (110, 120) is designed as a double-contact structure. Even if the male connector 20 is disconnected from one of the contacts of the terminals (110, 120), there is still another contact in contact. Therefore, each layer of terminals (110, 120) can always be in contact with the male connector 20, avoiding the situation of disconnection, eliminating the phenomenon of momentary disconnection, and improving the connection reliability.

[0059] refer to Figure 7 , the front end of the terminal along the plugging direction is defined as the contact end 110a, and the rear end along the plugging direction is defined as the fixed end 110b. Figure 7 As shown, the contact end 110a is set to a bent structure bent along the height direction, and the two surfaces (a1, a2) of the bent contact end 110a facing each other are contacts for contacting an external connector. Figure 14 The two contacts a1 and a2 contact with the clip of the Type-C male connector 20 to form a double-contact contact.

[0060] That is to say, each layer of terminals of the Type-C female connector 10 has two contacts a1 and a2 that contact the Type-C male connector 20, which increases the connection reliability. Even if the connector becomes loose and one of the two contacts separates from the Type-C male connector 20, there is still another contact to contact, thus avoiding momentary disconnection.

[0061] In other embodiments, Figure 8 As shown, double-point contact can also be achieved by setting the contact end 110a of the terminal 110 to a bifurcated structure to form two contact pieces 1101. Figure 8As shown, the contact end 110a of the terminal 110 is divided into two contact pieces 1101 by the bifurcation, and the two faces of the two contact pieces 1101 facing away from each other are the contact points, or the two opposite faces of the two contact pieces 1101 are the contact points. Specifically, as shown in Figure 15 As shown, the two faces of the two contact pieces 1101 facing away from each other are the contact points, Figure 15 As shown, the two faces of the two contact pieces 1101 facing away from each other are the contact points, Figure 16 As shown, the two opposite faces of the two contact pieces 1101 are the contact points, Figure 16 As shown, the two opposite faces of the two contact pieces 1101 are the contact points.

[0062] Figure 14 As shown, the bifurcation of the front end of the terminal 110 to form double contact points makes the front end of the terminal 110 a circular arc surface, which is more conducive to guiding the female seat 20, thereby making the insertion smoother.

[0063] As shown in Figure 15 As shown in Figure 16 As shown in the bifurcation of the front end of the terminal 110 to form two contact points, although the bending guiding effect is not as good as the first embodiment, an arc guiding surface can be formed at the front end of each contact piece 1101 to guide the female seat 20, thereby ensuring the smoothness of the insertion.

[0064] As shown in Figure 7 In an embodiment, the contact end 110a of the terminal is bent into a U-shaped structure. The mouth of the U-shaped structure faces the fixed end of the terminal, and the bottom of the U-shaped structure faces the insertion end of the female seat. The two sides of the U-shaped structure are the contact points, specifically, the two faces of the two sides of the U-shaped structure facing away from each other are the contact points. As shown in Figure 7 As shown in

[0065] As shown in Figure 7 As shown, the contact end 110a is bent to form a bent portion 110aa and a main body portion 110ab, and the bent portion 110aa is parallel to the main body portion 110ab. In combination with Figure 14 The parallelism of the bent portion 110aa and the main body portion 110ab makes the connection of the terminal (110, 120) and the female seat 20 more stable.

[0066] As shown in Figure 5 As shown, the contact ends of the upper terminal 110 and the lower terminal 120 are bent towards each other. That is, the upper terminal 110 is bent downward, and the lower terminal 120 is bent upward.

[0067] It has been verified that the connection of the terminal after bending and the female seat has the same transmission effect compared with the traditional single contact point contact, and does not affect the signal transmission efficiency and other performances.

[0068] In an embodiment, as shown in Figure 3 and Figure 5 , the Type-C female connector 10 further comprises an insulating piece 130. Referring to Figure 5 , the insulating piece 130 comprises a base 130a, an upper tongue 130b and a lower tongue 130c. The upper tongue 130b and the lower tongue 130c are both extended forward from the base 130a along the insertion direction, and the upper tongue 130b and the lower tongue 130c are arranged in a vertical manner. The upper terminals 110 and the lower terminals 120 are respectively embedded in the upper tongue 130b and the lower tongue 130c, and the contact points are exposed. Specifically, the fixed ends 110b of the upper terminals 110 and the fixed ends of the lower terminals 120 are both fixed in the base 130a, the contact ends 110a of the upper terminals 110 are embedded in the upper tongue 130b and the contact points are exposed, and the contact ends of the lower terminals 120 are embedded in the lower tongue 130c and the contact points are exposed. The portions of the terminals that need to be insulated are covered and insulated by the insulating piece 130, and the contact points are exposed to contact the male seat 20. Meanwhile, as shown in Figure 3 , the ends of the fixed ends of the terminals are also exposed, and the ends of the fixed ends are used for welding with the circuit board.

[0069] In an embodiment, as shown in Figure 2 , the Type-C female connector 10 further comprises a metal shell 140. The metal shell 140 is sleeved on the outside of the insulating piece 130. The metal shell 140 is grounded. Specifically, as shown in Figure 2 , the bottom of the metal shell 140 is provided with a soldering leg 141, which is inserted into the circuit board and welded, that is, the metal shell 140 is connected to the ground wire of the circuit board, so as to realize grounding. As shown in Figure 1 , the metal shell 140 is further sleeved with a plastic shell 150, and the plastic shell 150 is provided with a clamping position 151, so as to be clamped with the male seat 20 through the clamping position 151 on the plastic shell 150.

[0070] In combination with Figure 4 and Figure 5 , the Type-C female connector 10 further comprises an upper shielding sheet 161 and a lower shielding sheet 162. The upper shielding sheet 161 and the lower shielding sheet 162 are respectively embedded in the upper tongue 130b and the lower tongue 130c. As shown in Figure 5 , among the plurality of terminals of the upper terminals 110, the upper ground terminals 111 and other types of terminals, such as communication terminals, are included. The upper shielding sheet 161 is in contact with the upper ground terminals 111 and the metal shell 140, so as to form a ground loop.

[0071] Similarly, the plurality of terminals of the lower layer terminal 120 includes a lower layer ground terminal 121 and other types of terminals, such as communication terminals. The lower layer shielding sheet 162 is in contact with the lower layer ground terminal and the metal shell 140, thereby forming a ground loop.

[0072] Specifically, as shown in Figure 3 , after the upper layer shielding sheet 161 and the lower layer shielding sheet 162 are embedded in the tongue plate, the shielding sheet on both sides in the width direction has an exposed grounding point 161a of the insulating member 130. When the metal shell 140 is sleeved on the insulating member 130, the grounding point 161a of the shielding sheet is in abutment with the metal shell 140, thereby realizing the connection between the shielding sheet and the metal shell 140.

[0073] The connection between the ground terminal and the shielding sheet also adopts a direct abutment mode. In combination with Figure 7 and Figure 9 , the upper layer shielding sheet 161 is arranged between the main body part 110ab and the bent part 110aa of the upper layer terminal 110, and the lower layer shielding sheet 162 is arranged between the main body part and the bent part of the lower layer terminal 120. In combination with Figure 9 and Figure 9 , the front end of the upper layer shielding sheet 161 along the insertion direction is provided with a first through hole 1611, and the front end of the lower layer shielding sheet 162 along the insertion direction is provided with a second through hole 1621. As shown in Figure 9 , the contact end of the upper layer ground terminal 111 passes through the first through hole 1611 and is bent, and the front end H of the bent part is in abutment with the front side wall of the first through hole 1611. As shown in Figure 9 , similarly, the contact end of the lower layer ground terminal 121 passes through the second through hole 1621 and is bent, and the front end of the bent part is in abutment with the front side wall of the second through hole 1621.

[0074] The arrangement of the shielding sheet between the main body part 110ab and the bent part 110aa of the corresponding terminal not only facilitates the abutment between the ground terminal and the shielding sheet, but also facilitates the reduction of the thickness of the tongue plate. By arranging the shielding sheet between the main body part 110ab and the bent part 110aa of the terminal, the shielding sheet is placed in the bending space, which is more conducive to making the tongue plate thinner than placing the shielding sheet outside the terminal, such as on the upper side or the lower side of the terminal.

[0075] As shown in Figure 9 , the ground terminal is shorter than other terminals in the insertion direction. The ground terminal refers to the upper layer ground terminal 111 and the lower layer ground terminal 121. As shown in Figure 6The front end of the upper layer ground terminal 111 is obviously more backward than other terminals in the upper layer terminal 110, that is, shorter than other terminals in the upper layer terminal 110, which is more conducive to passing the upper layer ground terminal 111 through the first through hole on the upper layer shielding sheet 161 and abutting against the upper layer ground terminal 111, and other terminals can be directly bent to the lower side of the upper layer shielding sheet 161 due to being longer, and other terminals are not in contact with the upper layer shielding sheet 161. Similarly, the lower layer ground terminal is also shorter. At the same time, the ground terminal is shorter, which is also conducive to distinguishing the ground terminal from other terminals.

[0076] In the embodiment of the application, the shielding sheet can also not be arranged. Since the terminal in the embodiment of the application adopts a double-layer structure, the traditional upper row of terminals and the lower row of terminals integrated in one layer are divided into two independent layers, the double-layer terminals are spaced apart in the height direction and are far apart, so they almost do not interfere with each other, and the shielding sheet can be cancelled. Of course, the shielding sheet can also be arranged, so that the shielding effect is better.

[0077] As shown in Figure 6 , the insulating piece 130 includes a first insulating piece 131, a second insulating piece 132, and a third insulating piece 133. The first insulating piece 131 and the second insulating piece 132 are both "7" shaped. As shown in Figure 10 , the first insulating piece 131 includes a first plate portion 1311 and a first base portion 1312 perpendicular to each other. The second insulating piece 132 includes a second plate portion 1321 and a second base portion 1322 perpendicular to each other. The first insulating piece 131 and the second insulating piece 132 are stacked, and then integrally injection molded to form the third insulating piece 133. Specifically, referring to Figure 10 , the molding process of the Type-C male connector 20 is as follows:

[0078] The upper layer terminal 110 and the upper layer shielding sheet 161 are installed on the first insulating piece 131, the fixed end 110b of the upper layer terminal 110 is inserted into the first base portion 1312 of the first insulating piece 131, the contact end 110a of the upper layer terminal 110 is supported on the first plate portion 1311 of the first insulating piece 131, the first shielding sheet is inserted into the first insulating piece 131, and the upper layer shielding sheet 161 is located at the bottom of the first plate portion 1311. At this step, the upper layer terminal 110 is not bent yet, and the upper layer terminal 110 is bent after the second insulating piece 132 is combined with the first insulating piece 131;

[0079] Continuing to refer to Figure 10The lower layer terminal 120 is fixed on the second insulating member 132, the fixed end of the lower layer terminal 120 is inserted into the second base 1322 of the second insulating member 132, the contact end of the lower layer terminal 120 extends forward along the insertion direction, and the lower layer terminal 120 is located below the second plate 1321 at a distance, the lower layer shielding sheet 162 is inserted into the second base 1322, and the lower layer shielding sheet 162 is located below the second plate 1321 at a distance, and the lower layer terminal 120 is bent, wherein the ground terminal 121 of the lower layer terminal 120 is bent through the second through hole 1621 on the lower layer shielding sheet 162.

[0080] As shown in Figure 6 , the second insulating member 132 is stacked with the first insulating member 131 to form an integral whole, the second plate 1321 of the second insulating member 132 abuts against the bottom of the first plate 1311 of the first insulating member 131, the upper layer shielding sheet 161 is clamped between the second plate 1321 and the first plate 1311, and the second base 1322 of the second insulating member 132 abuts against the front side of the first base 1312 of the first insulating member 131, the upper layer terminal 110 is bent downward, and the ground terminal 111 of the upper layer terminal 110 is bent through the first through hole 1611 on the upper layer shielding sheet 161 when bent.

[0081] The assembled first insulating member 131 and second insulating member 132 are integrally injection molded, that is, the third insulating member 133 in Figures 11 to 13 is formed, and after integrally injection molding, the first insulating member 131, the second insulating member 132, the upper layer terminal 110, the lower layer terminal 120, the upper layer shielding sheet 161, and the lower layer shielding sheet 162 form an integral whole.

[0082] In the above structure, the "7" shaped structure of the first insulating member 131 and the second insulating member 132 is beneficial to the positioning between the two, and is also beneficial to the positioning between the upper layer terminal 110 and the lower layer terminal 120, thereby ensuring the fixation of the relative positions between the two layers of terminals.

[0083] In the above structure, the first base 1312 of the first insulating member 131 and the second base 1322 of the second insulating member 132 are stacked together to form the base of the insulating member 130, the first plate 1311 of the first insulating member 131 and the second plate 1321 of the second insulating member 132 are stacked together to form the upper layer tongue plate 130b of the insulating member 130, and then the lower layer tongue plate 130c of the insulating member 130 and the insulating filling part connecting the parts into an integral whole and other parts requiring insulation are formed by integrally injection molding.

[0084] The embodiment of the present application also discloses a Type-C male connector. The Type-C male connector is applied to the above-mentioned Type-C female connector 10. Figure 13 As shown, the Type-C male connector 20 includes an upper clip 210 and a lower clip 220. The upper clip 210 is suitable for clamping the upper terminal 110 of the above-mentioned Type-C female connector 10, as shown in FIG. Figure 11 As shown, the upper clip 210 includes two clip arms 211 arranged opposite to each other in the height direction, and the two clip arms 211 respectively contact the two contacts of the upper terminal 110. The lower clip 220 is suitable for clamping the lower terminal 120 of the above-mentioned Type-C female connector 10. Similarly, the lower clip 220 includes two clip arms arranged opposite to each other in the height direction, and the two clip arms respectively contact the two contacts of the lower terminal 120.

[0085] The Type-C male connector 20 is configured as a double-layer clip structure, which can clamp the Type-C female connector 10 having a double-layer terminal structure, where each layer of the terminal structure has two upper and lower contacts, thereby ensuring the reliability of the connection and avoiding momentary disconnection.

[0086] like Figure 12 and Figure 11 As shown, the Type-C male connector 20 further includes a front shell 230 and a rear shell 240. The front shell 230 is provided on the outside of the clips (210, 220) and can protect the clips (210, 220) and also serve as a guide during insertion. Figure 17 As shown, the rear shell 240 is arranged at one end of the front shell 230 away from the female base 10, and a buckle 241 is provided on the rear shell 240. Figure 1 As shown, the buckle 241 on the rear shell 240 can be engaged with the buckle position 151 on the female plastic shell 150, thereby fixing the male socket 20 and the female socket 10. Figure 11 As shown, a positioning surface H is provided on the female plastic housing 150. ​ As shown, the front end of the rear shell 240 of the male socket 20 is provided with a positioning surface R that cooperates with the positioning surface H of the female socket 10.
