[0041] The present application proposes a TYPE-C electrical connector 10.

[0042] Please refer to Figures 1 to 5In the first embodiment of the present application, a TYPE-C electrical connector 10 is provided, which includes a tongue plate 11, a housing 12, an upper row of pins 13 and a lower row of pins 14. The housing 12 is shaped by a metal shield, which internally surrounds a receiving cavity, and the second fixing portion 121 is integrally formed in the receiving cavity. The tongue plate 11 is a part of an insulator, which is forwardly overhangingly arranged in the receiving cavity along the insertion direction. The upper row of pins 13 is arranged on the upper side of the tongue plate 11, and the lower row of pins 14 is arranged on the lower side of the tongue plate 11 away from the upper row of pins 13. The tongue plate 11 is provided with the first fixing portion 111 along the side edge in the width direction shown in the drawings, and the first fixing portion 111 is located in the middle region between the upper row of pins 13 and the lower row of pins 14. It can be understood that the first fixing portion 111 is located between the upper row of pins 13 and the lower row of pins 14, which means that the first fixing portion 111 is located in the tongue plate 11, rather than protruding from the tongue plate 11.

[0043] During assembly, the tongue plate 11 with the upper row of pins 13 and the lower row of pins 14 is pushed into the receiving cavity of the housing 12 from the rear to the front along the insertion direction, and the first fixing portion 111 located between the upper row of pins 13 and the lower row of pins 14 is in transverse abutment with the second fixing portion 121. The second fixing portion 121 integrally formed with the housing 12 supports and increases the strength of the tongue plate 11 through the first fixing portion 111.

[0044] Preferably, the second fixing portion 121 includes a clamping plate 122 and a middle clamping grounding sheet 123. The clamping plate 122 is integrally connected with the housing 12, which provides electrical connection and strong mechanical support for the second fixing portion 121. The middle clamping grounding sheet 123 is arranged on the side of the clamping plate 122 facing the tongue plate 11, and is integrally connected with the clamping plate 122. The first fixing portion 111 is provided as a fixing groove, which extends along the insertion direction and is located in the middle region between the upper row of pins 13 and the lower row of pins 14. One end of the clamping plate 122 along the insertion direction of the tongue plate 11 is provided with a lead-in chamfer to provide a flexible lead-in and stable pre-tightening during assembly and use. During assembly, the tongue plate 11 with the upper and lower rows of pins 14 is led into the receiving cavity of the housing 12 from the rear to the front along the insertion direction, and the middle clamping grounding sheet 123 is controllably embedded in the fixing groove and forms a surface contact or a line-surface composite contact with the clamping surfaces on both sides of the fixing groove by means of the lead-in chamfer. In the final state of assembly, the middle clamping grounding sheet 123 provides rigid support for the tongue plate 11; the clamping plate 122 abuts against the side of the tongue plate 11 to provide pre-tightening and support for the middle clamping grounding sheet 123.

[0045] Optionally, the first fixing part 111 can be a regular, irregular, continuous, continuous, through the tongue plate 11 and not through the tongue plate 11 slot, but also can be through or not through the tongue plate 11 hole and other structures that can cooperate with the second fixing part 121 to strengthen the strength of the tongue plate 11. The card plate 122 can be adjusted according to the specific structure of the first fixing part 111. When the first fixing part 111 is an irregular structure, the card plate 122 is also an irregular structure, which can provide more favorable friction in the plug-in direction to prevent the tongue plate 11 from breaking. When the first fixing part 111 is a structure that penetrates the tongue plate 11, the card plate 122 is also a structure that penetrates the tongue plate 11. The card plate 122 that penetrates the tongue plate 11 can not only provide strong mechanical support to increase the strength of the tongue plate 11, but also effectively shield electromagnetic interference. When the second fixing part 121 is a structure that does not penetrate the tongue plate 11, a middle plate 15 can also be provided in the tongue plate 11, and the middle plate 15 is connected to the shell 12. It can be understood that the second fixing part 121 is integrally formed with the shell 12, and the middle plate 15 is also connected to the second fixing part 121. The middle plate 15 cooperates with the second fixing part 121 to shield electromagnetic interference while achieving the common purpose of enhancing the mechanical strength of the tongue plate 11.

[0046] In order to further enhance the strength of the tongue plate 11 and increase the service life of the tongue plate 11, a buffer block 16 is provided at one end of the tongue plate 11 along the plug-in direction. The buffer block 16 is located at the transition position of the tongue plate 11 and the plug-in area, and the front edge is provided with a lead-in chamfer or round corner. The buffer block 16 is provided with a fixed slot along the side edge in the width direction shown in the drawing, which is in communication with the fixed slot on the tongue plate 11 and is consistent in position. When assembling, the middle grounding sheet 123 is first inserted into the fixed slot on the buffer block 16. The setting of the buffer block 16 disperses the impact of plugging, reduces the stress concentration and wear of the tongue plate 11, enables the tongue plate 11 to obtain better bending and side swing resistance without increasing the overall thickness, and improves the service life of the tongue plate 11.

[0047] The accommodating cavity is provided with an upper grounding plate 125 and a lower grounding plate 126 covering the tongue plate 11 in the width direction, and the upper grounding plate 125 and the lower grounding plate 126 are integrally formed with the shell 12. The upper grounding plate 125 and the lower grounding plate 126 are located on the upper and lower sides of the tongue plate 11 respectively. The second fixing part 121 is located at both ends of the upper grounding plate 125 and the lower grounding plate 126 in the width direction. The upper grounding plate 125, the lower grounding plate 126 and the two second fixing parts 121 form a closed ring, and the tongue plate 11 passes through the ring. The upper grounding plate 125, the lower grounding plate 126 and the two second fixing parts 121 form a ring-shaped continuous grounding surface, which provides a stable electromagnetic environment for the differential pair, and provides rigid support for the tongue plate 11 through the second fixing part 121 at the end of the upper grounding plate 125 and the lower grounding plate 126, which takes into account mechanical reinforcement and electromagnetic interference shielding.

[0048] The inner partition plate 127 is integrally formed with the shell 12, and separates the tongue plate 11 from the insulator behind the tongue plate 11, and prevents the tongue plate 11 from being pulled out of the shell 12 when the plug is inserted. The upper grounding plate 125 and the lower grounding plate 126 are integrally formed on the inner partition plate 127, and the second fixing part 121 is integrally formed on the inner partition plate 127. It can be understood that the inner partition plate 127 provides support and electrical connection for the upper grounding plate 125, the lower grounding plate 126 and the second fixing part 121. The first through hole 128 is formed on the inner partition plate 127; the first through hole 128 is located between the upper grounding plate 125 and the lower grounding plate 126, and the tongue plate 11 is fixed in the first through hole 128. Specifically, during assembly, the tongue plate 11 with pins is introduced from back to front along the insertion and extraction direction, so that the outer edge of the tongue plate 11 is positioned in cooperation with the first through hole 128, and the tongue plate 11 is suspended in the accommodation cavity along the insertion and extraction direction.

[0049] The second fixing part 121 further includes a buckle 124 arranged on the side of the clamping plate 122 away from the tongue plate 11, and the buckle 124 is used to cooperate with the TYPE-C male head to prevent the TYPE-C male head from falling off the TYPE-C electrical connector 10 during use. In order to improve the yield of the integral molding process of the shell 12, a second through hole 129 is formed on the inner partition plate 127, and the second through hole 129 is located on the outer side of the second fixing part 121. It can be understood that the second fixing part 121 is integrally formed with the inner partition plate 127, and the second through hole 129 is located on the side of the second fixing part 121 away from the tongue plate 11. The second through hole 129 is adjacent to the clamping plate 122, and the width of the second through hole 129 is not less than the thickness of the buckle 124; that is, in the width direction, the projection length of the second through hole 129 is greater than the projection length of the buckle 124, so that the demolding process after the shell 12 is cast and formed will not damage the shell, thereby improving the yield.

[0050] In summary, the present application provides a TYPE-C electrical connector, which comprises: a tongue plate, the tongue plate is provided with a first fixing part on the side edge in the width direction; a shell, the shell has an accommodation cavity, and the accommodation cavity is provided with a second fixing part integrally formed with the shell; an upper row of pins, the upper row of pins is arranged on the upper side of the tongue plate; a lower row of pins, the lower row of pins is arranged on the lower side of the tongue plate; the first fixing part is located between the upper row of pins and the lower row of pins; wherein the first fixing part cooperates with the second fixing part to strengthen the strength of the tongue plate.
