[0037] Please refer to Figures 1 to 7 as shown, which shows the specific structure of the preferred embodiment of the present utility model, including an insulating body 10, a terminal group 20 and an outer shell 30.

[0038] The insulating body 10 has a plugging cavity 101 with an opening facing forward. A plurality of terminal slots 102 are formed inside the insulating body 10, and the plurality of terminal slots 102 communicate with the plugging cavity 101. In this embodiment, the insulating body 10 is provided with a fixing slot 103, and a convex portion 104 protrudes from the surface of the insulating body 10. In addition, a groove 105 is formed on the inner side wall of the rear end of the terminal slot 102. Specifically, the insulating body 10 includes a rubber core 11 and a rear plug 12. The aforementioned plugging cavity 101 and the plurality of terminal slots 102 are formed on the rubber core 11, and the rear plug 12 is arranged at the rear end of the rubber core 11.

[0039] The terminal group 20 includes a plurality of first terminals 21. The plurality of first terminals 21 are all arranged inside the insulating body 10. The plurality of first terminals 21 each include a first contact portion 211, a first main body portion 212, and a first welding portion 213 that are integrally formed and connected in sequence. The first contact portion 211 is located in the corresponding terminal slot 102 and protrudes out of the plugging cavity 101. The first main body portion 212 is located in the corresponding terminal slot 102. A clamping point 214 protrudes from the side surface of the first main body portion 212. The clamping point 214 has a guiding slope 2141, and the height of the guiding slope 2141 gradually increases from front to back. The clamping point 214 is embedded in the insulating body 10 on the side wall surface of the terminal slot 102. The first welding portion 213 protrudes out of the insulating body 10. In this embodiment, the terminal group 20 further includes a plurality of second terminals 22. The plurality of second terminals 22 are all arranged inside the insulating body 10. The plurality of second terminals 22 and the plurality of first terminals 21 are arranged alternately. Specifically, the plurality of second terminals 22 each include a second contact portion 221, a second main body portion 222, a bending portion 223, and a second welding portion 224 that are integrally formed and connected in sequence. The second contact portion 221 is located in the corresponding terminal slot 102 and protrudes out of the plugging cavity 101. The second main body portion 222 is located in the corresponding terminal slot 102. The bending portion 223 is bent and extended upward at the rear end of the second main body portion 222. The second welding portion 224 protrudes out of the insulating body 10 and is located above the first welding portion 213.

[0040] The housing 30 is sleeved on the insulating body 10. In this embodiment, a fixing portion 31 extends from the housing 30, and the fixing portion 31 is inserted into the fixing slot 103 for fixing. In addition, a card hole 32 is formed on the housing 30, and the card hole 32 is in snap-fit connection with the convex portion 104 for fixing.

[0041] The manufacturing process of this embodiment is described in detail as follows:

[0042] First, the rubber core 11 is injection molded, and then the first terminal 21 and the second terminal 22 are inserted into the rubber core 11. When the first main body 212 enters the terminal groove 102, the card point 214 contacts the front inner wall surface of the groove 105 and squeezes and deforms it. The design of the groove 105 can reduce the resistance of the first terminal 21 to the plastic of the rubber core 21, which is more conducive to the assembly of the first terminal 21. Subsequently, the card point 214 enters the terminal groove 102 and is embedded in the plastic of the rubber core 11. The height of the guide slope 2141 gradually increases from front to back, so that when the first terminal 21 is inserted forward, the first terminal 21 is subjected to a downward pressure, so that the first terminal 21 is inserted forward and downward, so that the bottom of the first terminal 21 can better adhere to the lower inner wall of the terminal groove 102, thereby improving the consistency and stability of the finished product.

[0043] The design focus of this utility model is:

[0044] By protruding a card point on the side of the first main body, the card point is embedded in the insulating body on the side wall of the terminal groove, so that the first terminal and the insulating body are assembled more firmly and reliably. In addition, the card point has a guide slope, and the height of the guide slope gradually increases from front to back, so that when the first terminal is inserted into the insulating body, the first terminal will be subjected to a downward pressure, so that the bottom of the first terminal can better adhere to the lower inner wall of the terminal groove. After the assembly is completed, the first terminal will not tilt up and down, thereby improving the consistency and stability of the finished product.

[0045] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
