[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0029] Reference Figures 1 to 5A TYPE-C female connector provided by an example of the utility model includes two terminal moldings 1, a middle clip 2, a secondary molding 3 and a shell 4. The middle clip 2 is arranged between the two terminal moldings 1. A positioning column 111 and a limiting hole 112 are arranged on one side of the two terminal moldings 1 close to the middle clip 2. The middle clip 2 is provided with two clamping parts 21. The two clamping parts 21 respectively accommodate two positioning columns 111 to be clamped. After the positioning column 111 on one terminal molding 1 is clamped into the clamping part 21, it enters the limiting hole 112 on the other terminal molding 1. After the two terminal moldings 1 and the middle clip 2 are assembled, the secondary molding 3 is obtained by injection molding. The two terminal moldings 1 and the middle clip 2 are embedded in the secondary molding 3, and the shell 4 is sleeved on the secondary molding 3. Therefore, the connection firmness of the two terminal moldings 1 and the middle clip 2 after assembly can be improved, and the phenomenon of components falling off during the turnover process can be avoided, thereby improving production efficiency and reducing product scrap rate.

[0030] Furthermore, the terminal molding 1 includes an injection molding body 11, a plurality of contact terminals 12 embedded in the injection molding body 11, a positioning column 111 and a limiting hole 112 are arranged on the injection molding body 11, one end of the plurality of contact terminals 12 extends out of the injection molding body 11, one side of the plurality of contact terminals 12 protrudes from the outer surface of the injection molding body 11, and after the two terminal moldings 1 are embedded in the secondary molding 3, one side of the plurality of contact terminals 12 protrudes from the outer surface of the secondary molding 3.

[0031] It can be understood that the portion of the contact terminal 12 extending from the injection molded body 11 can be conveniently connected to the device end, and the portion of the contact terminal 12 exposed from the secondary molding part 3 can be conveniently contacted with the terminal on the TYPE-C male connector.

[0032] It should be noted that the positioning column 111 , the limiting hole 112 and the injection molded body 11 are integrally formed, thereby improving production efficiency and the overall structural strength of the product.

[0033] Furthermore, the secondary molding component 3 includes a connecting portion 31 and a tongue portion 32, the connecting portion 31 is connected to the housing 4, the tongue portion 32 is located in the middle of the housing 4, and a space for accommodating the insertion of a TYPE-C male connector is formed between the tongue portion 32 and the housing 4, and one side surface of a plurality of contact terminals 12 protrudes from the outer surface of the tongue, thereby ensuring stability when mating with the TYPE-C male connector.

[0034] Furthermore, the injection molded body 11 is also provided with a through hole 113, and a gas avoidance hole 22 is provided in the middle of the middle clip 2. The through hole 113 is connected to the gas avoidance hole. When the two terminal moldings 1 and the middle clip 2 are assembled, injection molding is performed to obtain the secondary molding 3, so that the raw materials of the secondary molding 3 fill the through hole 113 on the injection molded body 11 and the gas avoidance hole 22 on the middle clip 2, thereby being able to wrap the injection molded body 11 and the middle clip 2 together to improve the overall firmness of the product.

[0035] In some preferred embodiments, the clamping portion 21 includes two symmetrically arranged clamping arms 211, which are in the shape of crab claws. The two clamping arms 211 are respectively used to clamp the two sides of the positioning column 111. When the positioning column 111 enters between the two clamping arms 211, the two clamping arms 211 expand outward, thereby clamping the positioning column 111 and improving the assembly firmness between the terminal molding 1 and the middle clip 2.

[0036] Specifically, the cross-section of the positioning column 111 is an arc portion 1111 and a plurality of convex ribs 1112 connecting the arc portion 1111. The plurality of convex ribs 1112 are symmetrically arranged along the symmetry center of the two clamping arms 211. A clamping space is formed between the two clamping arms 211. The clamping space is a rectangular structure and an arc structure connecting one side of the rectangular structure. The plurality of convex ribs 1112 are respectively interference fit with the three adjacent surfaces of the rectangular structure, and the arc portion 1111 is interference fit with the arc structure. Thus, the two clamping arms 211 and the positioning column 111 can be subjected to uniform force, and the wrapping strength of the two clamping arms 211 on the positioning column 111 is improved, thereby further improving the assembly firmness between the terminal molding 1 and the middle clip 2.

[0037] Furthermore, a guide portion 1113 is provided at the edge of the end of the positioning column 111. When the positioning column 111 enters between the two clamping arms 211, the two clamping arms 211 first abut against the guide portion 1113, and the two clamping arms 211 move along the inclined guide portion 1113 to the clamping surface of the positioning column 111, thereby facilitating the positioning column 111 to enter between the two clamping arms 211.

[0038] In some preferred embodiments, snap-fitting portions 23 are provided on both sides of the middle clip 2, and air avoidance grooves 33 are provided on both sides of the secondary molding part 3. The snap-fitting portions 23 protrude from the bottom of the air avoidance grooves 33. When the TYPE-C male connector is inserted, the buckle of the TYPE-C male connector is engaged with the snap-fitting portions 23, and the air avoidance grooves 33 can avoid the buckle of the TYPE-C male connector, thereby making the TYPE-C female socket and the TYPE-C male connector firmly connected.

[0039] In some preferred embodiments, at least one side of the secondary molding part 3 is provided with a groove 34, and the shell 4 is provided with at least two bending pieces 41, the two bending pieces 41 correspond to the groove 34, the two bending pieces 41 are folded into the groove 34 and limit the two sides of the groove 34 respectively, so that the shell 4 and the secondary molding part 3 can be assembled together, and the shell 4 and the secondary molding part 3 are firmly connected.
