[0020] For the convenience of understanding by those skilled in the art, the following further describes the present utility model in combination with the embodiments and the drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0021] As Figures 1 to 4 shown, a type-c connector provided by the present utility model includes a metal housing 1, a rubber core 2, a positive terminal 3, a negative terminal 4 and two hooks 5. The metal housing 1 is sleeved outside the rubber core 2. Slots 6 are opened on two opposite side walls of the metal housing 1. Latching blocks 7 are provided on two opposite outer side walls of the rubber core 2. The latching blocks 7 are latched with the slots 6. Limiting portions 8 are provided on both sides of the middle of the rubber core 2. The limiting portions 8 are used to abut against one end of the metal housing 1. An insertion slot 9 is concavely provided at one end of the rubber core 2 close to the metal housing 1. Two terminal slots 10 are concavely provided at one end of the rubber core 2 far from the metal housing 1. The two terminal slots 10 are both communicated with the insertion slot 9. The positive terminal 3 and the negative terminal 4 are respectively inserted into the two terminal slots 10. The inner ends of the positive terminal 3 and the negative terminal 4 are both located in the insertion slot 9. The outer end of the positive terminal 3 is provided with a positive electrode pad 11. The outer end of the negative terminal 4 is provided with a negative electrode pad 12. The positive electrode pad 11 and the negative electrode pad 12 are both exposed outside the rubber core 2. Insertion grooves 13 are provided on both sides of the rubber core 2. The insertion grooves 13 are communicated with the insertion slot 9. The limiting portion 8 is provided with a through hole 14. The through hole 14 is correspondingly communicated with the insertion groove 13. The hook 5 passes through the through hole 14 and is inserted into the insertion groove 13. The inner end of the hook 5 extends into the insertion slot 9. The outer end of the hook 5 is located outside the through hole 14 and is exposed outside the rubber core 2. The positive terminal 3 and the negative terminal 4 are located between the two hooks 5.

[0022] In practical applications, during assembly, the positive terminal 3 and the negative terminal 4 are inserted into the two terminal slots 10 of the rubber core 2. The inner ends of the positive terminal 3 and the negative terminal 4 are located in the insertion slot 9. The two hooks 5 are respectively inserted into the corresponding through holes 14 and insertion slots 13. The inner ends of the hooks 5 extend into the insertion slot 9. Then, the metal shell 1 is sleeved outside the rubber core 2. When the end face of the shell abuts against the limiting part 8, the clamping groove 6 just engages with the clamping block 7 to realize the clamping connection between the metal shell 1 and the rubber core 2, so as to complete the assembly of the type-c connector. Since the positive electrode pad 11 and the negative electrode pad 12 are exposed outside the rubber core 2 and are used for welding with external wires and the like, it is convenient for this type-c connector to be electrically connected to external electronic products. The utility model realizes the modular assembly of the type-c connector, which can be used after assembly, simplifies the structure of the type-c connector, reduces the number of parts, has low production cost, and improves the assembly efficiency.

[0023] In this embodiment, the positive electrode pad 11 is perpendicular to the outer end of the positive terminal 3; the negative electrode pad 12 is perpendicular to the outer end of the negative terminal 4. A limiting step 15 is provided in the middle of the rubber core 2; both the positive electrode pad 11 and the negative electrode pad 12 abut against the limiting step 15. This structural design facilitates the forming of the positive electrode pad 11 and the negative electrode pad 12, and is beneficial to the positioning and assembly of the positive terminal 3, the negative terminal 4 and the rubber core 2 when assembling the positive terminal 3 and the negative terminal 4.

[0024] In this embodiment, a limiting protrusion 16 is convexly provided at the outer end of the hook 5, and the limiting protrusion 16 is used to abut against the outer port of the through hole 14. By the limiting abutment of the limiting protrusion 16 and the outer port of the through hole 14, it is prevented that the hook 5 is inserted into the through hole 14 excessively, and the position accuracy and stability of the assembly of the hook 5 are improved.

[0025] In this embodiment, both the positive terminal 3 and the negative terminal 4 are provided with a first interference contact position 17, and the first interference contact position 17 abuts against the inner wall of the terminal slot 10. After the positive terminal 3 and the negative terminal 4 are respectively inserted into the corresponding terminal slots 10, the first interference contact position 17 abuts against the inner wall of the terminal slot 10, preventing the positive terminal 3 or the negative terminal 4 from disengaging from the terminal slot 10, and improving the stability of the positive terminal 3 and the negative terminal 4 after assembly.

[0026] In this embodiment, the hook 5 is provided with a second interference contact position 18, and the second interference contact position 18 abuts against the inner wall of the through hole 14. After the hook 5 is inserted into the through hole 14 and the insertion slot 13, the second interference contact position 18 abuts against the inner wall of the through hole 14, preventing the hook 5 from disengaging from the through hole 14 and the insertion slot 13, and improving the stability of the hook 5 after assembly.

[0027] In this embodiment, two oppositely arranged clamping elastic pieces 19 are provided at the inner ends of the positive terminal 3 and the negative terminal 4, and a clamping cavity 20 is formed between the two clamping elastic pieces 19. The external terminals are clamped and contacted by the two clamping elastic pieces 19 to maintain the stability of the connection.

[0028] Specifically, a clamping bump 21 protrudes from one side of the clamping elastic piece 19 located in the clamping cavity 20, and the external terminals are clamped and contacted by the two clamping bumps 21 to further maintain the stability of the connection.

[0029] All the technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiment is a preferred implementation solution of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
