[0020] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0021] Embodiment 1:

[0022] As Figures 1-2As shown, the Type-C electric connector of the embodiment includes an insulating main body 1 and a plurality of terminals 2 embedded in the insulating main body 1, wherein the terminals 2 include a mating portion 21, and the insulating main body 1 is bare, i.e. the insulating main body 1 is not provided with a shell. The Type-C electric connector further includes an outer frame 3 for improving the strength of the insulating main body 1, and the outer frame 3 is integrally processed with the insulating main body 1 by an injection molding process. By providing the outer frame 3, when a connector male head is inserted, the connector male head contacts the outer frame 3, thereby protecting the insulating main body 1 when the connector male head is inserted. In the embodiment, one outer frame 3 is provided on each side of the insulating main body 1. The outer frame 3 is integrally processed with the insulating main body 1 by an injection molding process. The outer frame 3 is processed by powder metallurgy or forging, and the strength of the outer frame 3 is very high.

[0023] In the embodiment, the insulating main body 1 includes a signal end 11 and a fixed end 13, and the outer frame 3 includes a middle section 31 embedded in the insulating main body 1, a front section 32 extending from one end of the middle section 31 towards the signal end 11 and not being completely wrapped by the signal end 11, and a tail section 33 extending from the other end of the middle section 31 towards the outside of the fixed end 13 and used for fixing to a PCB. By fixing the tail section 33 to the PCB, the connection between the Type-C electric connector and the PCB can be more firm. Further, the tail section 33 is used for electrically connecting to the PCB, so that the outer frame 3 serves as a ground terminal of the Type-C electric connector. In the embodiment, the front section 32 is provided outside the signal end 11, and all surfaces of the front section 32 are bare except for a surface that is in contact with the side surface of the signal end 11. In this way, the outer frame 3 is convenient to use as a terminal, for example, as a ground terminal, so that the number of other terminals can be reduced, and the strength of the outer frame can be further increased. Since the front section 32 is provided outside the signal end 11, when a connector male head is inserted, the front section 32 can protect the signal end 11 of the insulating main body 1. The tail section 33 is electrically connected to the PCB, so that the outer frame 3 serves as a ground terminal of the Type-C electric connector.

[0024] In the embodiment, the tail section 33 extends from the side surface 131 of the fixed end 13.

[0025] In the embodiment, the front section 32 is provided with a clamping protrusion 39, and the clamping protrusion 39 is used for clamping a connector male head inserted into the Type-C electric connector.

[0026] In the embodiment, the upper surface of the front section 32 is higher than the upper surface 111 of the signal end 11, so that the outer frame 3 is also used as a terminal.

[0027] In the embodiment, the Type-C electrical connector further comprises a crossbeam 5 connecting the front sections 32 of the two outer frame members 3. By arranging the crossbeam 5, the overall rigidity of the Type-C electrical connector can be further improved. The crossbeam 5 is integrally formed with the two outer frame members 3, so that the Type-C electrical connector is more convenient to process.

[0028] In the embodiment, the crossbeam 5 is inlaid at the front end of the signal end 11.

[0029] By arranging the outer frame member, the strength of the Type-C electrical connector can be greatly improved, the Type-C electrical connector can be saved from the metal shell and the middle steel sheet for holding the male connector, the structure of the Type-C electrical connector is simplified, the outer frame member can also be used as a grounding terminal, a pair of grounding terminals can be saved, and since the outer frame member is made of metal with high density, the center of gravity tends to the rear part when there is no shell, which is beneficial to the balance of the product during welding. By arranging the crossbeam and inlaying the crossbeam at the front end of the signal end, the damage to the Type-C electrical connector caused by the insertion of the male connector in a skewed position can be prevented, thereby playing a role in protecting the Type-C electrical connector from misinsertion.

[0030] As a simple modification of the embodiment, the Type-C electrical connector can also not be provided with the crossbeam 5 connecting the front sections 32 of the two outer frame members 3.

[0031] Embodiment 2:

[0032] As shown in Figure 3 The Type-C electrical connector of the embodiment has an insulating body 91, a terminal 92 and an outer frame member, which are the same as those of Embodiment 1. The difference between the embodiment and Embodiment 2 is that the inner side surface of the front section 932 of the outer frame member is provided with a groove 9321, and the signal end 911 of the insulating body 91 is embedded in the groove 9321. During injection molding, the plastic liquid forming the insulating body 91 will flow into the groove 9321, so that the signal end 911 of the insulating body 91 is embedded in the groove 9321. By arranging the groove 9321, the insulating body 91 and the outer frame member can be combined more firmly. In the embodiment, the groove 9321 extends a distance towards the middle section of the outer frame member.

[0033] As a simple modification of Embodiment 2, the front section is arranged on the outer side of the signal end, the inner side surface of the front section is provided with a protrusion, and the protrusion is embedded in the outer side surface of the signal end. In this way, the insulating body and the outer frame member can be combined more firmly.

[0034] The above merely describes preferred embodiments of the present application, but is not intended to limit the scope of the present application, and any equivalent changes and modifications made according to the present application are intended to fall within the scope of the present application, and are not listed one by one here.
