[0030] 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.

[0031] Reference Figures 1 to 4 An example of the utility model provides an insert molded part, which includes a hook part 1, a terminal component, an EMC component and a shell 4.

[0032] Structurally, the terminal assembly includes two terminal moldings 2 , which are clamped on the upper and lower sides of the hook member 1 . The terminal moldings 2 include a first colloid 21 , a terminal 22 embedded in the first colloid 21 , and slide rails 211 are provided on both sides of the first colloid 21 .

[0033] The EMC assembly includes two EMC molded parts 3, which are arranged on a side of the terminal molded part 2 away from the hook part 1. The EMC molded part 3 includes a second colloid 31 and an EMC spring 32 embedded in the second colloid 31. Slide grooves 311 are arranged on both sides of the second colloid 31, and a limiting block 312 is arranged on one side of the slide groove 311.

[0034] During assembly, the two terminal moldings 2 are first clamped on the upper and lower sides of the hook member 1, and then the two slide rails 211 on the first colloid 21 are respectively inserted into the two slide grooves 311 on the second colloid 31, and the first colloid 21 and the second colloid 31 are connected by a snap-on assembly, so that the two EMC moldings 3 are respectively connected to the two terminal moldings 2, and finally, the shell 4 is covered on the outer periphery of the two EMC moldings 3, thereby improving the assembly firmness of the parts, preventing the scattering of parts caused by the turnover of semi-finished products, reducing the scrap rate of products, and improving production efficiency.

[0035] Moreover, a connection port 41 is disposed at one end of the shell 4, and an insertion port 42 is disposed at the other end of the shell 4. The insertion port 42 is used to be inserted into a Type-C female connector (not shown in the drawings).

[0036] In some preferred embodiments, the snap-on assembly includes a snap 212 and a slot 313. The snap 212 is arranged on the first colloid 21, and the slot 313 is arranged on the second colloid 31. The snap 212 is snapped into the slot 313. During assembly, the first colloid 21 and the second colloid 31 can be connected together without using tools, thereby improving the convenience of assembly.

[0037] Reference Figure 2 and Figure 5 Specifically, the buckle 212 is a right-angled trapezoidal structure, and a guide groove 314 is provided on the second colloid 31. The guide groove 314 has a guide inclined surface 3141, and the guide inclined surface 3141 corresponds to the inclined surface of the right-angled trapezoidal structure. When the slide rail 211 is inserted into the slide groove 311, the inclined surface in the buckle 212 abuts against the guide inclined surface 3141, and a force is applied to the guide inclined surface 3141, so that the second colloid 31 is elastically deformed, thereby facilitating the buckle 212 to be inserted into the slot 313.

[0038] Furthermore, the slot 313 is located at a section of the second colloid 31 close to the connection port 41 , so that the section of the second colloid 31 close to the connection port 41 bulges outwards, and accordingly, the section of the housing 4 close to the connection port 41 widens outwards along the outer circumference.

[0039] In some preferred embodiments, the first colloid 21 is provided with a positioning column 213 , and the hook member 1 is provided with a positioning hole 11 for accommodating the positioning column 213 to pass through, thereby facilitating the positioning between the hook member 1 and the terminal molding 2 .

[0040] Furthermore, the first colloid 21 is also provided with a positioning groove 214, wherein a positioning column 213 on one first colloid 21 passes through the positioning hole 11 and then cooperates with the positioning groove 214 on the other first colloid 21, thereby connecting the two first colloids 21 together, further improving the firmness of product assembly.

[0041] The two ends of the terminal 22 respectively have a first contact point sequence 221 and a second contact point sequence 222. The first contact point sequence 221 is located at the connecting port 41. The first contact point sequences 221 of the two terminals 22 respectively contact the upper and lower surfaces of the PCB board (not shown in the drawings), and the second contact point sequences 222 of the two terminals 22 respectively contact the upper and lower surfaces of the tongue in the Type-C female connector.

[0042] Specifically, the first contact point sequence 221 is a wavy structure, and the opposite sides of the two first contact point sequences 221 have two protrusions 2211, and the two protrusions 2211 are in contact with the PCB board, thereby increasing the solder contact area, enhancing the soldering firmness of the PCB board, and effectively reducing the incidence of cold soldering and false soldering defects, as well as the stress separation and fracture of the solder joints of the PCB board and the terminal 22 caused by unstable welding, thereby reducing the incidence of defects and reducing defect costs.

[0043] Furthermore, the second colloid 31 is provided with a plurality of terminal grooves 315, and the plurality of terminal grooves 315 respectively accommodate the ends of the second contact point sequences 222. When the tongue piece in the Type-C female connector is inserted between two second contact point sequences 222, the two second contact point sequences 222 will undergo elastic deformation, and the plurality of terminal grooves 315 can avoid the elastic deformation of the second contact point sequences 222.

[0044] Reference Figure 3 and Figure 4 Furthermore, hooks 12 extend outward on both sides of one end of the hook member 1, and connecting feet 13 extend outward on both sides of the other end of the hook member 1. The two hooks 12 are respectively located on both sides of the second contact point sequence 222, and the two connecting feet 13 are respectively located on both sides of the first contact point sequence 221. The two second colloids 31 form accommodating grooves 316 for accommodating both sides of the hook member 1, and one side of the connecting foot 13 protrudes from the accommodating groove 316 and contacts with the inner wall of the shell 4.

[0045] On the one hand, when the tongue in the Type-C female connector is inserted between the two second contact point sequences 222, the two hooks 12 respectively clamp the two sides of the tongue in the Type-C female connector, thereby improving the firmness of the Type-C male connector and the Type-C female connector when used together; on the other hand, the accommodating groove 316 protrudes from one side of the connecting pin 13 and abuts against the inner wall of the shell 4, which can fix the hook member 1, the terminal assembly, the EMC assembly and the shell 4 together to prevent the parts from loosening and improve the assembly firmness.

[0046] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
